NATIONAL   SEMICONDUCTOR  PROVIDES  UPDATE  ON  STRATEGIC  ACTIONS  TO  INCREASE
PROFITABILITY FOR SHAREHOLDERS

o        Company on track to achieve $120 million annualized cost savings
o        Progressing on sale of Information Appliance business unit
o        Closing Cellular Baseband business

SANTA CLARA, CA - May 21, 2003 -- National Semiconductor  Corporation (NYSE:NSM)
today  announced  that it is on track in  implementing  a  series  of  strategic
profit-improvement  actions  that were  launched on  February  20,  2003.  These
actions  are  designed  to  streamline  National's  cost  structure  and enhance
shareholder   value  by  prioritizing  R&D  spending  on  higher-margin   analog
businesses.  Total cost savings  from these  profit-improvement  activities  are
expected to be  approximately  $30 million per quarter,  or  approximately  $120
million annually.

As part of that  plan,  the  company  had  indicated  it would  seek to sell its
Information  Appliance (IA) unit, which consists primarily of the GeodeTM family
of   microprocessor   products,   and  its  Cellular   Baseband  business  unit.
Approximately  $16 million of the $30 million  total  targeted  cost  savings is
related to the exit of the IA and baseband  business  units.  The Geode  product
family and  baseband  businesses  account for less than 5 percent of  National's
total revenue.

Since February, the company has conferred with several prospective buyers of the
IA business  unit and is actively  pursuing a sale.  In the  meantime,  National
continues to support existing customer programs. Although the company is engaged
in  discussions  with  potential  buyers,  it cannot give assurance that a sales
transaction will take place.


In addition, the company announced that effective immediately, it is closing its
cellular  baseband business unit. In connection with these steps, the company is
reducing its worldwide workforce by approximately 340 positions for the business
units   affected  and  related   support   functions  as  well  as  for  various
infrastructure    reductions    consistent    with   the    company's    overall
profit-improvement  objectives. Because of these actions, the company will incur
charges of  approximately  $25 to $30 million in the fourth quarter,  which ends
May 25, 2003, for severance and impairment of certain assets.

To date, under the profit-improvement  plan, the company has taken the following
steps:

o    Revised   its   technology   and   manufacturing   agreement   with  Taiwan
     Semiconductor Manufacturing Corporation (TSMC) in Q3.
o    Reduced its  workforce by 500 in Q3 and 340 in Q4, for a total of 8 percent
     of National's workforce.  After these actions are completed,  National will
     have approximately 9,200 employees.
o    Announced the closure of its cellular  baseband  business unit effective in
     Q4.

Approximately  $15 million of the $30 million in planned  quarterly cost savings
was achieved  through  actions  implemented  in the third  quarter.  The actions
announced  today will provide an  additional  $9 to $10 million  towards the $30
million  target.  The remainder would be achieved upon completion of the sale of
the Information Appliance business unit.

"We are moving  quickly to execute our plans to provide higher returns sooner to
shareholders,"  said Brian L. Halla,  National's  chairman,  president  and CEO.
"These  steps  increase our  operating  margins as we focus our  investments  in
National's  high-value,  high-margin  analog products such as power  management,
portable power, displays, audio and op amp solutions."

National  also  indicated  that it has not changed its revenue  guidance for the
fourth quarter.  The original  guidance in March was for fourth quarter revenues
to  increase  4 to 7 percent  from the  third  quarter,  equating  to a range of
approximately $420 to $432 million.

An update  about these  strategic  profit-improvement  actions will be available
June 5, when  National  Semiconductor  announces  fourth  quarter  and  year-end
financial results for its 2003 fiscal year.


This release contains forward-looking  statements dependent on a number of risks
and uncertainties.  These factors include, but are not restricted to, new orders
received and shipped during the remainder of the fourth  quarter,  the degree of
factory  utilization,  the successful  sale of existing  inventories at existing
prices, the ramp up of recently introduced  products,  and the timely completion
of the actions  updated above.  Other risk factors are included in the company's
10-Q for the third  quarter ended  February 23, 2003,  and the 10-K for the year
ended May 26,  2002 (see the  Outlook  section of  Management's  Discussion  and
analysis  of Results of  Operations  and  Financial  Conditions)  and the Annual
Report dated May 26, 2002.
