As of November 29, 1998, there were options outstanding to purchase 29.9 
million shares of the Company's common stock with a weighted-average 
exercise price of $15.29, which could potentially dilute basic earnings per 
share in the future, but which were not included in the computation of 
diluted earnings per share as their effect was antidilutive.  As of 
November 29, 1998, the Company also had outstanding $258.8 million of 
convertible subordinated notes, which are convertible into approximately 
6.0 million shares of common stock.  These notes were not assumed to be 
converted in the computation of diluted earnings per share because they 
were antidilutive in all periods presented.

Comprehensive Income:
- --------------------
Beginning in fiscal 1999, the Company adopted Statement of Financial 
Accounting Standards ("SFAS") No. 130, "Reporting Comprehensive Income," 
which establishes standards for reporting and display of comprehensive 
income and its components.  SFAS No. 130 requires the Company to include 
unrealized gains or losses on the Company's available-for-sale securities 
and minimum pension liability, which were previously reported as separate 
components of shareholder's equity, in other comprehensive income. 

The components of accumulated other comprehensive loss are as follows:

Note 2.	Short-term Borrowings
Included in short-term borrowings and current portion of long-term debt at 
November 29, 1998, is $10 million which the Company borrowed under its 
revolving credit agreement.  The borrowing bears interest at 7.75 percent 
and was repaid on November 30, 1998.

Note 3. 	Restructuring of Operations
In October 1998, the Company announced plans to consolidate its wafer 
manufacturing operations in Greenock, Scotland and to seek investors to 
acquire and operate the facility in Greenock as an independent foundry 
business.  This action was prompted by continued weakness in the 
semiconductor market, which has resulted in overall lower capacity 
utilization of the Company's manufacturing facilities.  The Company will 
close its 4-inch wafer fabrication facility ("Fab 1") and consolidate Fab 1 
manufacturing into its 6-inch wafer fabrication facility on the same site.  
The Company will also move some of the Greenock capacity to its 
manufacturing facility in Arlington, Texas.  This action will reduce the 
Greenock workforce by approximately 600 employees and is expected to be 
completed within 12 to 18 months.  The Greenock assets have been treated as 
assets to be held and used since they cannot be removed immediately from 
operations.  In connection with the closure of Fab 1, the Company recorded 
a restructuring charge of $21.3 million in its second quarter ended 
November 29, 1998.  The charge included $11.9 million for severance, $3.9 
million for costs associated with the dismantling of Fab 1 and 
approximately $5.5 million for other related exit costs.  Other costs 
associated with this action, which will be charged to future operations, 
include approximately $20-$25 million for process transfer costs and 
approximately $6-$8 million for retention bonuses.  The process transfer 
costs will be expensed as incurred and the retention bonuses will be 
expensed ratably as earned over the employees' service period.  In 
addition, accelerated depreciation on the Greenock assets of approximately 
$9.0 million per quarter will be incurred over the next 12 to 18 months.

Subsequently in December 1998, the Company engaged the services of an 
investment banker to assist in seeking a potential investor to acquire and 
operate the Greenock facility.  

The charge for consolidating Greenock was offset by an $8.8 million release 
of excess reserves related to certain prior restructure actions.  The 
release included $2.8 million of severance, $2.3 million of asset write-
offs and $3.7 million of other exit costs.  The release of excess reserves 
was prompted by the completion during the quarter of remaining actions 
associated with the closure of the Company's 5-inch and 6-inch wafer 
fabrication facilities in Santa Clara, California and a worldwide workforce 
reduction plan.  The timing of these actions was consistent with the 
timetable previously announced in April 1998.  In addition, the Company was 
able to sell or transfer to its other manufacturing facilities 
substantially all of the surplus assets from the 5-inch and 6-inch wafer 
fabrication facilities.  

The net restructure charge is reported as a special item in the statement 
of operations for the second quarter ended November 29, 1998.

Note 6.  One-Time Charge Associated with Contract Termination
On September 25, 1998, the Company announced that it had reached agreement 
with International Business Machines Corporation ("IBM") for termination of 
the wafer manufacturing and marketing agreement that previously existed 
between its Cyrix Corporation ("Cyrix") subsidiary and IBM.  Under terms of 
the agreement, the Company's Cyrix subsidiary has been relieved of its 
obligations to purchase wafers from IBM and IBM has ceased the competitive 
sale of Cyrix-designed processors to customers other than National.  In 
addition, Cyrix transferred ownership of certain assets to IBM that 
physically resided at an IBM facility.  As a result of the contract 
termination and asset transfers, the Company incurred a one-time charge of 
$48.6 million recorded in cost of sales in its second quarter ended 
November 29, 1998.  The one-time charge included $30.6 million for the 
write-off of manufacturing assets transferred to IBM and $18 million for the 
write-off of prepaid wafer purchases and other costs associated with 
terminating the original agreement.

Note 7.  Contingencies

In July 1996, the Company received notices of assessment from the Malaysian 
Inland Revenue Department totaling approximately 146.9 million Malaysian 
ringitts ($38.7 million).  In December 1998, the Company received 
additional notices of assessment totaling approximately 53.0 million 
Malaysian ringitts ($14.0 million).  The issues giving rise to the July 
1996 and December 1998 assessments primarily relate to intercompany 
transfer pricing for the Company's manufacturing operations in Malaysia for 
fiscal year 1985 through 1993.  The Company believes the assessments are 
without merit and has been contesting them administratively.  The Company 
believes it has adequate tax reserves to satisfy the ultimate resolution of 
the assessments.



ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
         AND RESULTS OF OPERATIONS

Overview	The Company recorded net sales of $510.1 million and $979.7 
million for the second quarter and first six months of fiscal 1999, 
respectively.  This represents a 29.1 percent and 28.8 percent decrease 
from net sales of $719.9 million and $1,376.6 million, respectively, for 
the same periods of fiscal 1998.  Lower sales were partially due to a 
general slowdown in new orders driven by continued economic uncertainties 
in the Asia Pacific region, which the Company experienced through the 
second quarter of fiscal 1999.  Also contributing to lower sales was 
continuing weak demand for network (formerly local area networks) products, 
due to the Company's delays in introducing key new network products.  And 
in the Company's processor business, significant price reductions were 
experienced in the Cyrix 6X86 line of products due to increased competition 
and availability of new higher speed processor products from competitors.

A net loss of $94.4 million and $199.2 million was recorded for the second 
quarter and first six months of fiscal 1999, respectively, compared to net 
income of $28.9 million and $91.5 million for the same periods of fiscal 
1998.   The net loss was primarily attributable to lower sales and margin 
erosion mainly due to lower factory utilization.  In addition, the Company 
recorded certain charges in the second quarter of fiscal 1999.  The charges 
included a $21.3 million charge for restructuring of operations related to 
the announced consolidation of its wafer manufacturing operations in 
Greenock, Scotland (See Restructuring of Operations).  This restructure 
charge was offset by an $8.8 million release of excess reserves related to 
certain prior restructure actions, which were substantially completed 
during the quarter.  The net restructure charge is reported as a special 
item in the statement of operations.  The Company also recorded a one-time 
charge of $48.6 million included in cost of sales for costs associated with 
the termination of a wafer manufacturing and marketing agreement between 
its Cyrix subsidiary and IBM.  Special items included in the comparable 
quarter of fiscal 1998 included a $2.5 million charge for in-process 
research and development ("R&D") related to the acquisition of Future 
Integrated Systems, Inc. ("FIS"), plus a $30.0 million charge related to 
certain merger and related expenses in connection with the Cyrix 
Corporation acquisition.

Sales	 The decline in sales was a result of lower volume combined with 
price erosion in most of the Company's product areas.  Sales for analog 
products declined in the second quarter and first six months of fiscal 1999 
by 23.9 percent and 23.3 percent, respectively, from sales for the same 
periods of fiscal 1998.  General weakness experienced by the Company in the 
personal computer and communications product related markets caused the 
overall decline in sales for the Company's analog products, as well as, 
sales for personal computer related peripheral products and wide area 
networks ("WAN") products.  Sales for network products declined 65.3 
percent and 67.1 percent in the second quarter and first six months of 
fiscal 1999, respectively, over sales for the same periods of fiscal 1998, 
as the Company continued to experience declining shipments and price 
erosion in its existing mature 10/100 megabit ethernet products.  The 
Company's failure to introduce key new network products during fiscal 1998 
was the primary cause of the sharp drop in fiscal 1999.  Despite 
significant improvement in unit sales of Cyrix M II products, competitive 
price pressure caused processor revenue to decline 6.0 percent and 16.6 
percent in the second quarter and first six months, respectively, from the 
same periods in fiscal 1998.  Sales of certain other personal computer 
related peripheral products declined by approximately 50 percent and 46 
percent in the second quarter and first six months of fiscal 1999, 
respectively, compared to the same periods of fiscal 1998.  Sales for  
WAN products (including application specific wireless communication 
products), a product area which had previously experienced continued growth, 
also declined.  WAN product sales declined 24.0 percent and 7.8 percent in 
the second quarter and first six months of fiscal 1999, respectively, from 
the same periods of fiscal 1998, reflecting lower unit shipments while unit 
prices generally remained flat.

Gross Margin  	Gross margin as a percentage of sales declined to 18.2 
percent and 15.1 percent for the second quarter and first six months of 
fiscal 1999, respectively, compared to 39.4 percent and 39.5 percent for 
the same periods in fiscal 1998.  Excluding the effect of the one-time 
charge related to the IBM contract termination, gross margin for the second 
quarter and first six months of fiscal 1999, was 27.8 percent and 20.1 
percent, respectively.  The primary factor contributing to the decline in 
gross margin continued to be lower factory utilization.  While the IBM 
action has enabled the Company to ramp-up its own microprocessor 
manufacturing and more fully utilize the capacity available in its 
0.35/0.25 micron wafer fabrication facility in Maine, factory utilization 
declined from 86 percent for the second quarter of fiscal 1998 to 62 
percent for the second quarter of fiscal 1999.  However, the Company has 
achieved sequential quarterly improvements in gross margin as factory 
utilization in the second quarter of fiscal 1999 increased over the rate of 
41 percent for the first quarter.  With the exception of Maine, the Company 
continued to run its other manufacturing facilities at reduced capacity 
utilization rates in order to manage inventory levels and control cost.  
The decline in gross margin also reflects continued price erosion, 
particularly in the Cyrix microprocessor products.

Research and Development	  Research and Development ("R&D") expense 
for the second quarter of fiscal 1999 decreased 6.3 percent from the 
comparable quarter of fiscal 1998, while year over year for the first six 
month period R&D expenses increased slightly by 1.0 percent.  R&D expenses 
for the second quarter and first six months of fiscal 1998 included a $2.5 
million special charge for in-process R&D related to the acquisition of 
FIS.  Excluding the effect of this special charge from the comparable 
periods in fiscal 1998, R&D expenses in the second quarter and first six 
months of fiscal 1999 decreased 4.3 percent and increased 2.1 percent, 
respectively.  The decrease in R&D expense quarter to quarter, reflects the 
Company's efforts to align its R&D spending with current business 
conditions.  Overall, the Company's R&D expenses continue to be heavily 
focused on advanced submicron CMOS process technology, which is consistent 
with one of the Company's stated strategic imperatives.  The Company has 
also invested resources in the development of Cyrix microprocessor-based 
products.  Its efforts have been focused on the development of new 
microprocessor cores and the integration of those cores with the Company's 
other technological capabilities in order to develop system-on-a-chip 
products.  The Company also continues to invest resources in the 
development of new analog and mixed-signal technology based products for 
applications in the personal systems, communications and consumer markets.  
R&D spending for fiscal 1999 for process technology continued to grow over 
the fiscal 1998 spending levels.  However, this growth was offset by a 
decline in spending for product development as part of management's 
alignment of spending with current business conditions.  Through the first 
six months of fiscal 1999, the Company devoted approximately 33 percent of 
its R&D effort towards the development of process technology and 67 percent 
towards new product development.

Selling, General and Administrative	  Selling, general and administrative 
("SG&A") expenses for the second quarter and first six months of fiscal 
1999 decreased by 13.2 percent and 14.0 percent, respectively, from the 
same periods in fiscal 1998.  The decrease reflects certain cost reduction 
actions taken by the Company to reduce its overall cost structure in 
response to weakened business conditions in both the current fiscal year 
and second half of fiscal 1998.  As a percentage of sales, SG&A expenses 
for the second quarter and first six months of fiscal 1999 remained nearly 
flat compared to the same periods of fiscal 1998.

Restructuring of Operations 	In October 1998, the Company announced plans 
to consolidate its wafer manufacturing operations in Greenock, Scotland and 
to seek investors to acquire and operate the facility in Greenock as an 
independent foundry business.  This action was prompted by continued 
weakness in the semiconductor market, which has resulted in overall lower 
capacity utilization of the Company's manufacturing facilities.  The 
Company will close its 4-inch wafer fabrication facility ("Fab 1") and 
consolidate Fab 1 manufacturing into its 6-inch wafer fabrication facility 
on the same site.  The Company will also move some of the Greenock capacity 
to its manufacturing facility in Arlington, Texas.  This action will reduce 
the Greenock workforce by approximately 600 employees and is expected to be 
completed within 12 to 18 months.  The Greenock assets have been treated as 
assets to be held and used since they cannot be removed immediately from 
operations.  In connection with the closure of Fab 1, the Company recorded 
a restructuring charge of $21.3 million in its second quarter ended 
November 29, 1998.  The charge included $11.9 million for severance, $3.9 
million for costs associated with the dismantling of Fab 1 and 
approximately $5.5 million for other related exit costs.  Other costs 
associated with this action, which will be charged to future operations, 
include approximately $20-$25 million for process transfer costs and 
approximately $6-$8 million for retention bonuses.  The process transfer 
costs will be expensed as incurred and the retention bonuses will be 
expensed ratably as earned over the employees' service period.  In 
addition, accelerated depreciation on the Greenock assets of approximately 
$9 million per quarter will be incurred over the next 12 to 18 months.

Subsequently in December 1998, the Company engaged the services of an 
investment banker to assist in seeking a potential investor to acquire and 
operate the Greenock facility.  

The charge for consolidating Greenock was offset by an $8.8 million release 
of excess reserves related to certain prior restructure actions.  The 
release included $2.8 million of severance, $2.3 million of asset write-
offs and $3.7 million of other exit costs.  The release of excess reserves 
was prompted by the completion during the quarter of remaining actions 
associated with the closure of the Company's 5-inch and 6-inch wafer 
fabrication facilities in Santa Clara, California and a worldwide workforce 
reduction plan.  The timing of these actions was consistent with the 
timetable previously announced in April 1998.  In addition, the Company was 
able to sell or transfer to its other manufacturing facilities 
substantially all of the surplus assets from the 5-inch and 6-inch wafer 
fabrication facilities.  The net restructure charge is reported as a 
special item in the statement of operations for the second quarter ended 
November 29, 1998.

Interest Income and Interest Expense	Net interest expense was $0.3 
million and $0.2 million for the second quarter and first six months of 
fiscal 1999, respectively, compared to net interest income of $3.4 million 
and $15.1 million for the same periods in fiscal 1998.  Net interest 
expense was attributable to less interest earned on lower cash balances 
combined with lower interest expense due to reduced debt balances.  
Capitalized interest associated with capital expansion projects had no 
effect on interest expense quarter to quarter.  For the first six months of 
fiscal 1999, the Company capitalized $0.2 million of interest associated 
with capital expansion projects, which was recorded in the first quarter.  
This compares to $5.4 million of interest capitalized for the first six 
months of fiscal 1998, which was also recorded in the first quarter.

Other Income/Expense, Net	Other expense, net was $8.3 million and $8.0 
million for the second quarter and first six months of fiscal 1999, 
respectively.  This compares to other income, net of $1.9 million and $9.3 
million for the same periods in fiscal 1998.  For the second quarter of 
fiscal 1999, other expense, net included $0.1 million of net intellectual 
property income and a $0.3 million gain on the sale of technology.  This 
was offset by a $7.0 million settlement of intellectual property rights and 
a $1.7 million net loss on equity investments primarily attributable to the 
write-down of an investment to net realizable value.  For the second 
quarter of fiscal 1998, other income, net included $1.9 million of net 
intellectual property income and a $1.8 million gain from the sale of stock 
from the Company's investment holdings.  This was offset by a $1.8 million 
loss from foreign exchange forward contracts.  Including the items 
previously described, other expense, net for the first six months of fiscal 
1999 included an additional $0.3 million of net intellectual property 
income for a total $0.4 million.  This compares to other income, net for 
the first six months of fiscal 1998, which included a $8.4 million net gain 
from the sale of stock from the Company's investment holdings and $2.7 
million of net intellectual property income, offset by a $1.8 million loss 
from foreign exchange forward contracts.

Income Tax Provision/Benefit	Income tax benefit for fiscal 1999 is based 
on the Company's expected effective tax rate of 25 percent. 

Financial Condition	During the first six months of fiscal 1999, cash 
and cash equivalents decreased by $39.7 million compared to a $181.0 
million decrease for the first six months of fiscal 1998.  A decrease in 
capital expenditures for fiscal 1999 from fiscal 1998 was a primary factor 
in the difference.  The Company expended $156.1 million for investment in 
property, plant and equipment in fiscal 1999 compared to a $366.3 million 
investment in fiscal 1998.  This was partially offset by less cash 
generated from operating activities of $107 million in fiscal 1999 compared 
to $178.7 million in fiscal 1998, as well as less cash generated from 
financing activities of $6.6 million in fiscal 1999 compared to $37.3 
million in fiscal 1998.  Operating cash was negatively impacted by the 
losses incurred in fiscal 1999, but was positively impacted by the 
Company's efforts to increase working capital.  The primary contributor to 
improved working capital trends was a significant reduction in inventories.  
The decline in cash generated from financing activities in fiscal 1999 was 
primarily due to less proceeds from the issuance of common stock under the 
Company's employee stock programs due to the decline in the Company's stock 
price.

Management foresees substantial cash outlays for plant and equipment 
throughout fiscal 1999 with primary focus on capacity expansion in the 
Maine 8-inch wafer fabrication facility, next generation process capability 
and implementation and expansion of in-house assembly and test capacity for 
Cyrix microprocessors.  In the second quarter of fiscal 1999, management 
increased the planned level of capital expenditure for the year from the 
level originally estimated in the first quarter.  However, total capital 
expenditures in fiscal 1999 are still expected to be significantly lower 
than in fiscal 1998.  Existing cash and investment balances, together with 
existing lines of credit, are expected to be sufficient to finance planned 
fiscal 1999 capital investments.

Outlook     The statements contained in this Outlook and in the Financial 
Condition section of Management's Discussion and Analysis are forward 
looking based on current expectations and management's estimates.  Actual 
results may differ materially from those set forth in these forward looking 
statements.  In addition to the risk factors discussed in the Financial 
Condition and Outlook sections of Management's Discussion and Analysis of 
Financial Condition and Results of Operations on pages 24 through 28 of the 
Company's 1998 Annual Report on Form 10-K for the fiscal year ended May 31, 
1998 filed with the Securities and Exchange Commission, the following 
factors may also affect the Company's operating results for fiscal 1999:

Business conditions for the semiconductor industry and the Company remained 
weak through the fall quarter, although the Company experienced improvement 
in order rates in the second quarter over the previous quarter.  In 
particular, orders for personal computer related products showed signs of 
seasonal improvement.  The Company also saw a very high order turns 
environment in the second quarter.  However, this higher turns rate of 
orders results in a lack of forward visibility into the post-Christmas 
period.  As a result, there is no assurance that the improvement in order 
rates is more than the seasonal pick-up typically experienced through the 
end of the calendar year.  Therefore, the Company continues to be cautious 
about its future outlook.  The Company also has traditionally faced the 
risk of a drop in order rates in the personal computer industry after the 
Christmas holiday.  While the Company may experience sequential growth in 
sales for the third quarter, based on current conditions, it expects to 
incur a loss for the third quarter of fiscal 1999.

The Company's focus also has shifted toward the consumer segment of the 
personal computer market since the acquisition of Cyrix.  As a result, the 
Company faces the risk that its overall business will be affected by the 
higher degree of seasonality associated with the consumer segment.  Based 
on a growing supply of microprocessor products in the PC industry, the 
Company anticipates a more aggressive pricing environment for its 
microprocessor business during calendar 1999.  The Company will also 
experience increased pressure to rapidly release new processors with higher 
operating speeds to respond to growing competition in the sub-$1,000 PC 
market.  The Company's inability to endure future price competition or to 
release new processors in a timely fashion will cause an unfavorable impact 
on future sales and results of operations.

The Company's future sales and results of operations may also be 
unfavorably affected by the following additional factors.  Since the spring 
quarter of fiscal 1998, the Company has devoted efforts to develop new 
network products based on digital signal processing technology in order to 
recover its market position in the networks business.  The Company 
anticipates the development of those products, which include the QuadPhyter 
and the MacPhyter to generate sample revenue beginning in the fourth 
quarter of fiscal 1999 and production revenue in the first quarter of 
fiscal 2000.  The effect of these new products to the Company's sales and 
results of operations is dependent on whether the Company encounters 
unforeseen obstacles or schedule delays, and receives acceptance by 
customers.  During the second quarter the Company also experienced 
increased order activity from its European and Korean customers for the 
Company's products that support mobile phone handsets.  There is a risk 
that this increased activity is seasonal or that these orders may be 
subsequently cancelled similar to a trend experienced by the Company last 
year.  

Unless new orders substantially improve from the rate of orders currently 
experienced, the Company will continue to run its manufacturing facilities 
at reduced capacity utilization rates to manage inventories and reduce 
cost.  Consequently, gross margin will continue to be adversely affected.  
The Company will continue to ramp-up wafer starts in its 8-inch wafer 
fabrication facility in Maine to support the Cyrix products.  It will also 
continue to aggressively transfer processes out of the 4-inch wafer 
fabrication facility in Greenock into the 6-inch wafer fabrication facility 
on the same site.  The Company will also move some of the capacity to its 
manufacturing facility in Arlington, Texas.  These actions are expected to 
improve future capacity utilization.  In the short-term, the Company will 
incur incremental transfer costs and accelerated depreciation related to 
the 4-inch wafer fabrication facility action.  As a result, the Company 
expects gross margin to improve just slightly over gross margin in the fall 
quarter.

In October 1998, the Company announced plans to consolidate its wafer 
manufacturing operations in Greenock, Scotland.  It also plans to seek 
investors to acquire and operate the facility in Greenock as an independent 
foundry business.  As a result, the Company will close its 4-inch wafer 
fabrication facility ("Fab 1") and consolidate Fab 1 manufacturing into the 
remaining 6-inch wafer fabrication facility on the same site.  This action 
will reduce the Greenock workforce by approximately 600 employees and is 
expected to be completed within 12 to 18 months.  In connection with this 
action, the Company recorded a restructure charge of $21.3 million in its 
second quarter ended November 29, 1998.  Other costs associated with this 
action, which will be charged to future operations, include approximately 
$20-$25 million for process transfers costs and approximately $6-$8 million 
for retention bonuses.  The process transfer costs will be expensed as 
incurred and the retention bonuses will be expensed ratably as earned over 
the employees' service period.  In addition, accelerated depreciation on 
the Greenock assets of approximately $9.0 million per quarter will be 
incurred over the next 12 to 18 months.  Future operating results may be 
unfavorably affected if the Company encounters unexpected delays or other 
problems related to these actions.  The Company may be unsuccessful in 
seeking investors to acquire the operations under terms acceptable to the 
Company.  Retention of the manufacturing operations may have an unfavorable 
impact on the Company's future operating results.  It is also difficult to 
predict the final impact on the Company's future operating results of the 
planned spinout, since the structure and timing have not yet been 
determined.

The following discussion supplements the discussion included in the Outlook 
section of Management's Discussion and Analysis of Financial Condition and 
Results of Operations in the Company's 1998 Annual Report on Form 10-K for 
the fiscal year ended May 31, 1998, related to the Company's efforts to 
undertake year 2000 projects.  To date the Company has devoted a 
substantial portion of its year 2000 efforts evaluating, modifying and 
testing its critical business applications, manufacturing tools and 
computer systems to be year 2000 ready by the beginning of calendar 1999.  
Failure to successfully complete year 2000 projects could cause significant 
disruption of operations.  Such disruptions may include, but are not 
limited to, interruption of manufacturing activities, and inability to 
process invoices, payments or other systematic business transactions.  The 
Company believes that the largest remediation effort and greatest risk from 
year 2000 issues arise from its manufacturing and logistics operations.  
Failure to successfully implement year 2000 modifications in manufacturing 
tools and related systems could result in the inability to manufacture and 
deliver products to customers.  Projects related to the Company's 
manufacturing processes are expected to be completed by May 1999.  The 
Company is also currently evaluating its exposure to contingencies related 
to the year 2000 issues for products it has sold.  The Company believes 
that its products do not directly contain specific calendar year functions.  
However, customers may use the Company's products in conjunction with 
customer supplied software over which the Company has no control that may 
perform non-compliant year 2000 date computations.  As a result, there is a 
risk of litigation associated with the use of such products by customers.  
Such risks include all the uncertainties and cost associated with 
litigation.  While there can be no assurance that unforeseen problems will 
not be encountered, the Company expects that all critical year 2000 
remediation projects will be completed on schedule.  Because of its focus 
in ensuring the remediation projects are on schedule, the Company has not 
yet fully developed contingency plans to address alternative solutions in 
the event the Company fails to successfully make any of its critical 
systems year 2000 ready.  The Company expects to begin the development of 
contingency plans around the beginning of calendar 1999.  At that time, the 
Company believes it will be better able to identify any deficiencies and 
appropriately develop specific contingency plans for further remediation 
efforts.

The forward looking statements discussed or incorporated by reference in 
this outlook section involve a number of risks and uncertainties.  Other 
risks and uncertainties include, but are not limited to, the general 
economy, regulatory and international economic conditions, the changing 
environment of the semiconductor industry, competitive products and 
pricing, growth in the personal computer and communications industries, the 
effects of legal and administrative cases and proceedings, and such other 
risks and uncertainties as may be detailed from time to time in the 
Company's SEC reports and filings.


ITEM 3.  QUANTITIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Reference is made to Part II, Item 7A, Quantitative and Qualitative 
Disclosures About Market Risk,  in the Company's Annual Report on Form 10-K 
for the year ended May 31, 1998 and to the subheading "Financial Market 
Risks" under the heading "Management's Discussion and Analysis of Financial 
Condition and Results of Operations" on page 28 of the Company's Annual 
Report on Form 10-K for the year ended May 31, 1998.

PART II. OTHER INFORMATION

Item 1.  Legal Proceedings
- --------------------------

Except as noted below, there have been no material developments in the 
legal proceedings reported in Item 3 in the Company's Annual Report on Form 
10-K for the year ended May 31, 1998.

On November 12, 1997, a class action lawsuit was filed in California State 
Court against the Company, Cyrix Corporation ("Cyrix"), Cyrix's Board of 
Directors and Cyrix's Chief Executive Officer by Goodman Epstein, 
individually and on behalf of Cyrix stockholders.  The complaint alleges 
that the named individual defendants breached their fiduciary duty to the 
stockholders of Cyrix in connection with their approval of Cyrix's merger 
with a subsidiary of the Company and that the Company further aided and 
abetted the alleged breach of fiduciary duty.  The complaint sought certain 
declaratory and injunctive relief, an accounting to the plaintiff and 
members of the class for the damages alleged to have been suffered, costs 
and fees.  An ex parte application filed by plaintiffs for a temporary 
restraining order, preliminary injunction and an expedited discovery order 
was scheduled to be heard on November 14, 1997, but was subsequently 
dropped by plaintiffs and was not heard.  In response to the demurrer filed 
by the defendants, plaintiff has filed its first amended complaint, adding 
as defendants the Company's directors, Donald Macleod, the Company's 
Executive Vice President, Finance and Chief Financial Officer, and Richard 
D. Crowley, Jr., the Company's Vice President and Controller.  The amended 
complaint alleged breach of fiduciary duty to the stockholders of Cyrix by 
the Company, Cyrix and the Cyrix individual defendants and violations of 
Sections 11 and 12(2) of the Securities Act of 1933 by all defendants and 
seeks certain declaratory and injunctive relief, an accounting to the 
plaintiff and class members for damages alleged to have been suffered, 
costs and fees.  The demurrer was granted in September 1998 with leave to 
amend, and a second amended complaint was filed in October 1998.  A motion 
to dismiss the second amended complaint is due to be heard on January 14, 
1999.  The Company believes the action is without merit and intends to 
contest it vigorously.

In July 1996, the Company received notices of assessment from the Malaysian 
Inland Revenue Department totaling approximately 146.9 million Malaysian 
ringitts ($38.7 million).  In December 1998, the Company received 
additional notices of assessment totaling approximately 53.0 million 
Malaysian ringitts ($14.0 million).  The issues giving rise to the July 
1996 and December 1998 assessments primarily relate to intercompany 
transfer pricing for the Company's manufacturing operations in Malaysia for 
fiscal year 1985 through 1993.  The Company believes the assessments are 
without merit and has been contesting them administratively.  The Company 
believes it has adequate tax reserves to satisfy the ultimate resolution of 
the assessments.
