                          LINEAR TECHNOLOGY CORPORATION
                   NOTES TO 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 month
     periods ended January 2, 2005 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 27, 2004
     included in the  Company's  Annual  Report on Form 10-K.  The  accompanying
     balance  sheet at June 27, 2004 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  work  year,  ending on the Sunday
     nearest  June  30.  Fiscal  year  2005 is a  53-week  work  year,  with the
     additional  week falling in the three month  period ended  January 2, 2005.
     Fiscal 2004 was a 52-week year. Accordingly, the three months ended January
     2, 2005 and December 28, 2003 are 14 and 13-week periods, respectively.

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.    Stock-Based Compensation

As  permitted  by SFAS 148 and SFAS  123,  the  Company  continues  to apply the
accounting provisions of APB 25, and related interpretations, with regard to the
measurement of compensation  cost for options granted under the Company's equity
compensation plans. Compensation expense is recorded if on the date of grant the
current fair value per share of the underlying  stock exceeds the exercise price
per share.

During the first quarter of fiscal 2005, the Company issued  restricted stock to
certain  officers  and  employees  who have been with the Company at least three
years to encourage employee  retention.  Under this program,  the Company issued
1,578,440  restricted  shares with an  exercise  price of $0.001 per share and a
grant date fair value of $37.05  per share.  The right to sell the shares  vests
annually  at the rate of 1/3 per year  based  upon  continued  employment;  upon


                                       6


employee  termination  the Company has the right to buy back unvested  shares at
the exercise price. Pursuant to APB 25, the Company records compensation expense
for the difference between the grant date fair value and the exercise price on a
straight-line basis over the vesting period.

Had expense been  recognized for stock options  granted with a grant price equal
to the  current  fair  market  value of the stock at the date of grant using the
fair value method described in SFAS 123, using the Black-Scholes  option-pricing
model, the Company would have reported the following results of operations:

5.       Accumulated Other Comprehensive Income

Accumulated other  comprehensive  income consists of unrealized gains and losses
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:

6.       Product Warranty and Indemnification

The Company's  warranty policy provides for the replacement of defective  parts.
In certain large contracts,  the Company has agreed to negotiate in good faith a
warranty expense in the event that an epidemic failure of its parts were to take
place.  To  date  there  have  been  no  such   occurrences.   Warranty  expense
historically has been negligible.

The Company provides a limited indemnification of customers against intellectual
property  infringement  claims  related to the  Company's  products.  In certain
cases, there are limits on and exceptions to the Company's  potential  liability
for indemnification  relating to intellectual  property  infringement claims. To
date,  the Company has not incurred  any  significant  indemnification  expenses
relating to  intellectual  property  infringement  claims.  The  Company  cannot
estimate the amount of potential future payments, if any, that the Company might
be  required  to make as a result  of these  agreements,  and  accordingly,  the
Company has not accrued any amounts for its indemnification obligations.

7.       Recent Accounting Pronouncements

In March 2004,  the Financial  Accounting  Standards  Board (FASB)  approved the
consensus  reached on the Emerging Issues Task Force (EITF) Issue No. 03-1, "The
Meaning  of  Other-Than-Temporary  Impairment  and Its  Application  to  Certain
Investments." The objective of this Issue is to provide guidance for identifying
impaired  investments.  EITF 03-1 also provides new disclosure  requirements for
investments  that are deemed to be  temporarily  impaired.  In October 2004, the
FASB delayed the effective date of the  accounting  provisions of EITF 03-1. The
disclosure  requirements  are effective for annual periods ending after June 15,
2004.  The Company  believes  that the adoption of EITF 03-1 will not affect the
overall results of operations or financial position of the Company.

In  December  2004,  the  Financial  Accounting  Standard  Board  (FASB)  issued
Statement  of  Financial   Accounting   Standard   (SFAS)  123  (Revised  2004),
"Shared-Based  Payment".  Revised SFAS 123  addresses the  requirements  that an
entity measure the cost of employee  services received in exchange for awards of
equity  instruments based on the grant-date fair value of the award. The cost of
such award  will be  recognized  over the period  during  which an  employee  is
required  to provide  services in exchange  for the award.  The Company  will be
required to adopt this Statement during the first quarter of fiscal year 2006.

As  permitted  by SFAS 123,  the  Company  currently  accounts  for  share-based
payments by applying  the  accounting  provisions  of APB 25's  intrinsic  value
method and, as such, the Company  generally  recognizes no compensation cost for
employee  stock  options.  Accordingly,  the adoption of Revised SFAS 123's fair
value  method  will  have a  significant  impact  on the  Company's  results  of
operations,  although  it will  have no added  impact on its  overall  financial
position. The impact of adoption of Revised Statement 123 cannot be predicted at
this time because it will depend on the level of share-based payments granted in
the future.  However, had the Company adopted Revised SFAS 123 in prior periods,
the impact of that standard would have  approximated the impact of Statement 123
as described in the disclosure of pro-forma net income and earnings per share in
Note 4.

8.       Subsequent Event

On January 18, 2005, the Company  announced that it had  accelerated the vesting
of unvested  stock  options  awarded more than one year prior to  employees  and
officers under its stock option plans that had exercise  prices greater than the
current  price of the stock  January  18,  2005  ($37.04).  Unvested  options to
purchase  approximately 4.5 million  additional  shares became  exercisable as a
result of the vesting acceleration.  Typically, the Company grants stock options
that vest  equally  over a  five-year  period.  The  purpose of the  accelerated
vesting is to enable the Company to avoid  recognizing  in its income  statement
compensation  expense  associated  with these  options in future  periods,  upon
adoption of FASB  Statement  No. 123R  (Share-Based  Payment) in July 2005.  The
charge to the income  statement  to be  avoided  amounts  to  approximately  $75
million over the course of the  original  vesting  period,  of which $36 million
would have occurred in fiscal 2006.

Item 2. Management's  Discussion and Analysis of Financial Condition and Results
        of Operations

Critical Accounting Policies

The  Company's  financial  statements  have been  prepared  in  accordance  with
accounting  principles generally accepted in the United States, which require it
to make estimates and judgments that  significantly  affect the reported amounts
of  assets,  liabilities,  revenues  and  expenses  and  related  disclosure  of
contingent  assets  and  liabilities.  The  Company  regularly  evaluates  these
estimates,   including   those  related  to  inventory   valuation  and  revenue


                                       8


recognition.   These  estimates  are  based  on  historical  experience  and  on
assumptions  that  are  believed  by  management  to  be  reasonable  under  the
circumstances.  Actual results may differ from these estimates, which may impact
the carrying values of assets and liabilities.

The Company believes the following critical  accounting policies affect the more
significant  judgments and estimates  used in the  preparation  of  consolidated
financial statements.

Inventory Valuation

The  Company  values  inventories  at the lower of cost or market.  The  Company
records charges to write down inventories for unsalable,  excess or obsolete raw
materials,  work-in-process  and  finished  goods.  Newly  introduced  parts are
generally not valued until success in the market place has been  determined by a
consistent pattern of sales and backlog among other factors. The Company arrives
at the estimate for newly released parts by analyzing sales and customer backlog
against  ending  inventory on hand.  The Company  reviews the  assumptions  on a
quarterly  basis and makes  decisions  with regard to the  reserve  based on the
current business  climate.  If actual market  conditions are less favorable than
those projected by management,  additional inventory write-downs may be required
that could adversely affect our operating  results.  If actual market conditions
are more favorable,  the Company may have higher gross margins when products are
sold.  Sales to date of such products  have not had a significant  impact on our
gross  margin.  In  addition  to  writedowns  based on newly  introduced  parts,
statistical  and  judgmental   assessments  are  calculated  for  the  remaining
inventory based on salability,  obsolescence,  historical experience and current
business conditions.

Revenue Recognition

Revenue from product  sales made  directly to customers is  recognized  upon the
transfer of title, which generally occurs at the time of shipment.  Revenue from
the  Company's  sales to domestic  distributors  is generally  recognized  under
agreements  which provide for certain  sales price  rebates and limited  product
return  privileges.  As a result,  the Company defers  recognition of such sales
until the  domestic  distributors  sell the  merchandise.  The Company  relieves
inventory  and records a receivable  on the initial sale to the  distributor  as
title has passed to the  distributor  and payment is collected on the receivable
within normal trade terms.  The income to be derived from  distributor  sales is
recorded under current  liabilities on the balance sheet as "Deferred  income on
shipments to distributors"  until such time as the distributor  confirms a final
sale to its end customer.

The Company's  sales to  international  distributors  are made under  agreements
which  permit  limited  stock  return  privileges  but not sales price  rebates.
Revenue on these sales is  recognized  upon shipment at which time title passes.
The Company has reserves to cover expected product  returns.  If product returns
for a particular fiscal period exceed or are below expectations, the Company may
determine  that  additional  or less sales  return  allowances  are  required to
properly reflect its estimated exposure for product returns. Generally,  changes
to sales  return  allowances  have not had a  significant  impact  on  operating
margin.

         Net sales for the quarter ended January 2, 2005 were $250.1 million, an
increase of $64.1  million or 34% over net sales of $186.0  million for the same
quarter of the previous fiscal year. The increase in net sales was primarily due
to the Company selling more units into a wide variety of end-markets in response
to improving overall demand. The average selling price for the second quarter of
fiscal 2005 was relatively  unchanged at $1.42 per unit as compared to $1.39 per
unit in the second quarter of fiscal 2004.  Geographically,  international sales
were  $184.8  million  or 74% of net  sales,  an  increase  of $54.6  million as
compared to  international  sales of $130.2  million or 70% of net sales for the
same period in fiscal 2004.  Internationally,  sales to Rest of the World (ROW),
which is primarily Asia excluding  Japan,  represented  $107.2 million or 43% of
net sales,  while  sales to Europe  and Japan  were $42.6  million or 17% of net
sales and $35.0 million or 14% of net sales,  respectively.  Domestic sales were
$65.3 million or 26% of net sales in the second  quarter of fiscal 2005 compared
to $55.8  million  or 30% of net sales in the same  period in fiscal  2004.  The
decline in the  percentage  of domestic  sales and the  related  increase in the
percentage of international  sales primarily results from the Company's domestic
customers shifting more of their manufacturing operations overseas.

         Net sales for the six months ended January 2, 2005 were $503.1 million,
an  increase of $143.0  million or 40% over net sales of $360.1  million for the
same  period of the  previous  fiscal  year.  The  increase in net sales for the
six-month period was due to similar factors as the three-month  period discussed
above.  The average selling price for the first six-month  period of fiscal 2005
was relatively  unchanged at $1.42 per unit as compared to $1.39 per unit in the
same  period of fiscal  2004.  Geographically,  international  sales were $367.9
million or 73% of net sales for the first  six-month  period of fiscal 2005,  an
increase of $111.2 million as compared to international  sales of $256.7 million
or 71% of net sales for the same period in fiscal 2004.  Internationally,  sales
to ROW,  represented  $209.2 million or 42% of net sales,  while sales to Europe
and Japan were $87.2 million or 17% of net sales and $71.5 million or 14% of net
sales,  respectively.  Domestic sales were $135.2 million or 27% of net sales in
the first  six-month  period of fiscal 2005 compared to $103.4 million or 29% of
net sales in the same period in fiscal 2004.  The decline in the  percentage  of
domestic sales and the related increase in the percentage of international sales
primarily results from the Company's  domestic  customers shifting more of their
manufacturing operations overseas.

         The Company ends every fiscal  quarter on the Sunday  nearest  calendar
month-end.  Roughly,  every five years the Company  has a 53-week  rather than a
52-week  fiscal  year.  Fiscal 2005 is a 53-week year with the  additional  week
falling in the  three-month  period ending January 2, 2005. The extra week had a
minimal  affect on revenue as it occurred  during the final  holiday  week.  The
extra week resulted in slightly  higher  compensation  costs in the Research and
Development  and  Selling,  General  and  Administrative  lines  of  the  Income
Statement. The increase in compensation costs for Cost of Goods Sold was largely
offset by lower per unit  manufacturing  costs  resulting  from an extra week of
production  volume.  The  Company  received  a benefit  from the  extra  week in
Interest  Income  because it accrued an extra week of  interest  income from its
cash investment balance.

         Gross  profit was $196.2  million  and  $394.4  million  for the second
quarter and first six-month  period of fiscal 2005, an increase of $54.0 million
and $119.5 million, respectively, from the corresponding periods of fiscal 2004.
Gross profit as a percentage of net sales increased to 78.5% of net sales in the
second  quarter of fiscal  2005 as  compared  to 76.5% of net sales for the same
period in the previous  fiscal year.  Gross profit as a percentage  of net sales
increased to 78.4% of net sales for the first six-month period of fiscal 2005 as
compared to 76.3% of net sales for the same period of the previous  fiscal year.
The  increase  in gross  profit as a  percentage  of net sales for the three and
six-month  periods  was  primarily  due to the  favorable  effect of fixed costs
allocated across higher  production  volumes in support of higher net sales. Net
sales increased 34% and 40% for the three and six-month periods in fiscal 2005.

         Research and development ("R&D") expenses for the quarter ended January
2, 2005 were $32.4 million, an increase of $7.4 million or 30% over R&D expenses
of $25.0 million for the same period in the previous  fiscal year.  The increase
in R&D was  primarily  due to a $6.7  million  increase in  compensation  costs.
Compensation related to the extra week of labor, increased headcount, and annual
merit increases together totaled $2.4 million;  compensation  expense related to
restricted stock grants totaled $1.9 million;  and, since the Company had better
operating  results,  R&D profit sharing grew $1.7 million.  The related employer
taxes and other fringe costs on these increases was $0.7 million. In addition to
compensation costs, the Company had a $0.7 million increase in other R&D related
expenses such as supplies and test wafers.

         Research  and  development  expenses  for the  six-month  period  ended
January 2, 2005 were $63.0 million, an increase of $13.7 million or 28% over R&D
expenses of $49.3 million for the same period in the previous  fiscal year.  The
increase in R&D was primarily due to a $12.5  million  increase in  compensation
costs. The increase in compensation  expense related to the extra week of labor,
increased  headcount and annual merit increases  together  totaled $3.8 million;
the increase in compensation  expense related to restricted stock grants totaled
$3.3 million;  and, since the Company had better operating  results,  R&D profit
sharing grew $4.3 million.  The related employer taxes and other fringe costs on
these increases was $1.1 million. In addition to compensation costs, the Company
had a $1.2 million increase in R&D related expenses such as supplies, mask costs
and test wafers.

         Selling,  general and administrative  expenses ("SG&A") for the quarter
ended  January 2, 2005 were $26.3  million,  an increase of $7.1  million or 37%
over SG&A expenses of $19.2  million for the same period in the previous  fiscal
year.  The  increase in SG&A was  primarily  due to a $5.0  million  increase in
compensation.  Compensation  related  to the  extra  week  of  labor,  increased
headcount and annual merit increases together totaled $1.3 million; compensation
expense related to restricted stock grants totaled $2.1 million;  and, since the
Company had better operating results, SG&A profit sharing grew $1.2 million. The
related  employer  taxes  and other  fringe  costs on these  increases  was $0.4
million.  In  addition to  compensation  costs,  the Company had a $2.1  million
increase in expenses  related to advertising,  increases in foreign sales office
cost  resulting from the weakening of the dollar,  increases in commissions  for
the Company's independent sales representatives and travel costs.

         Selling,  general and administrative  expenses for the six-month period
ended  January 2, 2005 were $49.4  million,  an increase of $12.6 million or 34%
over SG&A expenses of $36.8  million for the same period in the previous  fiscal
year.  The  increase in SG&A was  primarily  due to a $9.7  million  increase in
compensation costs.  Compensation related to the extra week of labor,  increased
headcount and annual merit increases together totaled $2.5 million; compensation
expense related to restricted stock grants totaled $3.4 million;  and, since the
Company had better operating results, SG&A profit sharing grew $3.2 million. The
related  employer  taxes  and other  fringe  costs on these  increases  was $0.6
million.  In  addition to  compensation  costs,  the Company had a $2.9  million
increase in expenses  related to advertising,  increases in foreign sales office
cost resulting from the weakening of the dollar,  commissions  for the Company's
independent sales representatives and travel costs.

         Interest income,  net was $7.2 million and $12.7 million for the second
quarter and first  six-month  period of fiscal 2005, an increase of $0.6 million
and a decrease $1.1 million,  respectively,  from the  corresponding  periods of
fiscal 2004.  The increase for the  three-month  period is primarily  due to the
extra week of accrued interest income.  The decrease for the six-month period is
primarily  due to the  decrease  in the  average  interest  rate  earned  on the
Company's cash investment balance, partially offset by the extra week of accrued
interest income and higher average cash investment balances.

         The Company's effective tax rate was 29% and 30% for the second quarter
and first  six-month  period of fiscal 2005.  The Company  anticipates  that its
effective  tax rate for fiscal 2005 will be 30%. The  increase in the  effective
tax rate from 29% to 30% results primarily from the diminishing  percentage that
tax-exempt interest income is of total taxable 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 the
Company's 10-K for the fiscal year ended June 27, 2004.

         In the second quarter of fiscal 2005 the Company reported a 34% and 38%
increase in sales and  profits,  respectively,  over the similar  quarter in the
previous  fiscal  year.  The  quarter  ended  January 2, 2005 met the  Company's
expectations with sales and profits down slightly from the September quarter. It
has  been  a  challenging  business  environment  due to  inventory  corrections
throughout  the various  sales  channels and also due to some  moderation in the
rate of growth of end-user  demand.  However,  the Company  believes  its ending
on-hand inventory at distributors is lean, and inventory turn ratios are high by
historic  standards.  Also, the Company's  distributors are projecting  moderate
increases  in sales  volume in the March  quarter  and lead times have  remained
unchanged at 4 to 6 weeks.  Accordingly,  although these are difficult times for
the  Company  to  forecast,  based  upon these and other  factors,  the  Company


                                       11


forecasts  that  revenues  for the March  quarter  will be  similar to that just
achieved during the December quarter, while profits will be down slightly due to
the increase in the effective tax rate from 29% to 30%.

         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 if 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 factors
described  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 January 2, 2005, cash, cash  equivalents and short-term  investments
totaled $1,731.9 million, and working capital was $1,730.7 million.

         Accounts  receivable  totaled  $97.5  million  at the end of the second
quarter of fiscal 2005,  an increase of $18.4 million from the end of the fourth
quarter of fiscal 2004. The increase is primarily due to higher shipments.  Days
sales outstanding  increased  slightly from 30 days to 36 days at the end of the
second quarter of fiscal 2005.

         Income taxes  payable  totaled  $60.7  million at the end of the second
quarter of fiscal 2005, a decrease of $11.3  million from the fourth  quarter of
fiscal  2004.  The  decrease is due to the higher  income tax  payments  and tax
benefits from stock option  transactions  partially  offset by higher income tax
expense.

         During  the first six  months of fiscal  2005,  the  Company  generated
$230.6 million of cash from  operating  activities and $39.4 million in proceeds
from common stock issued under employee stock plans.

         During  the  first  six  months  of  fiscal  2005,   significant   cash
expenditures  included the repurchase of $109.3  million in common stock,  $95.4
million from net purchases of short-term investments,  payments of $49.8 million
in cash dividends to stockholders representing $0.08 per share, and purchases of
$34.0 million for capital assets.  In January,  the Company's Board of Directors
declared  an  increase to the  quarterly  cash  dividend to $0.10 per share from
$0.08 per  share.  The $0.10 per share  dividend  will be paid  during the March
quarter  of  fiscal  2005.  The  payment  of future  dividends  will be based on
quarterly financial performance.

         As of January 2, 2005 the Company had no  off-balance  sheet  financing
arrangements.

         Historically,  the Company has satisfied  its  liquidity  needs through
cash  generated  from  operations.  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  Company's  Form 10-K for the
fiscal  year ended June 27,  2004.  There have been no  material  changes in the
market risk  affecting the Company  since the filing of the Company's  Form 10-K
for fiscal 2004.  At January 2, 2005,  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 municipal  bonds,  federal
agency bonds, commercial paper, 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.

         The Company's  sales  outside the United States are  transacted in U.S.
dollars;  accordingly the Company's  sales are not impacted by foreign  currency
rate changes. To date,  fluctuations in foreign currency exchange rates have not
had a material impact on the results of operations.

Item 4.     Controls and Procedures

(a) Evaluation of disclosure controls and procedures

         The Company's management evaluated, with the participation of the Chief
Executive  Officer and the Chief Financial  Officer,  the  effectiveness  of the
Company's disclosure controls and procedures as of the end of the period covered
by this  Quarterly  Report on Form  10-Q.  Based on this  evaluation,  the Chief
Executive  Officer  and the Chief  Financial  Officer  have  concluded  that the
Company's  disclosure  controls  and  procedures  are  effective  to ensure that
information that the Company is required to disclose in reports that it files or
submits  under  the  Securities  Exchange  Act of 1934 is  recorded,  processed,
summarized  and reported  within the time periods  specified in  Securities  and
Exchange Commission rules and forms.

(b) Changes in internal controls over financial reporting

         There was no change in the Company's  internal  control over  financial
reporting  that  occurred  during  the second  quarter  of fiscal  2005 that has
materially affected,  or is reasonably likely to materially affect, its internal
control over financial reporting.
