                               PROSPECTUS SUMMARY

    THE  FOLLOWING SUMMARY  IS QUALIFIED  IN ITS  ENTIRETY BY  THE MORE DETAILED
INFORMATION, INCLUDING "RISK FACTORS," APPEARING ELSEWHERE IN THIS PROSPECTUS.

                                  THE COMPANY

    Burr-Brown is a leader in the  design, development, manufacture and sale  of
high  performance  analog and  mixed signal  integrated circuits.  The Company's
products are  used  in  a  variety of  electronic  systems  for  communications,
computing,  industrial process control, test  and instrumentation, digital audio
and imaging.  The  Company offers  over  1,000 high  performance  products  that
perform  signal processing functions such as the conditioning, amplification and
filtering  of   analog   signals,   and   mixed   signal   functions   such   as
analog-to-digital and digital-to-analog conversion. Within its targeted markets,
Burr-Brown  emphasizes  high  performance applications  where  its  products are
critical elements of complex systems.

    The Company sells its  products to a diverse  base of over 30,000  customers
worldwide,  with key  customers including  Alcatel, AT&T,  Allen-Bradley, Canon,
Conner Peripherals, General Electric,  Hewlett-Packard, Hughes Network  Systems,
Nokia,  Northern Telecom, Siemens,  Sony, Teradyne and  Toshiba. The Company has
maintained long-term  relationships  with  major  customers  in  the  industrial
process  control, instrumentation and  imaging markets, and  typically serves as
the sole supplier of  proprietary products. Recently,  Burr-Brown has pursued  a
strategy  of  leveraging its  strengths in  analog  signal processing  and mixed
signal design  to develop  a broad  line  of standard  products for  the  faster
growing  communications, computing and  digital audio markets.  As a result, the
Company has established key new customer relationships with leading companies in
the wireless and high speed communications industry. In addition, several of the
Company's products  have  also  achieved  significant  market  acceptance  among
certain major suppliers in the personal computer industry.

    Burr-Brown maintains major manufacturing and technical facilities in Tucson,
Arizona;   Atsugi,  Japan;   and  Livingston,  Scotland.   In  1994,  Burr-Brown
established business units in  these locations to bring  greater focus on  their
respective  served markets  and accelerate  new product  development. Analog and
mixed signal circuit design is highly dependent on the skills and experience  of
individual  design engineers,  and Burr-Brown believes  that its  team of design
engineers has  developed core  strengths in  high performance  analog and  mixed
signal  integrated  circuits.  Since  the beginning  of  1994,  the  Company has
introduced over 90 new high performance products.

    The Company  sells  and markets  its  products in  major  markets  worldwide
through   approximately   75   direct   sales   personnel,   40   manufacturers'
representatives and 20  distributors. The Company's  direct sales force  focuses
primarily on large corporate customers, while the Company's distributors service
the  needs of the Company's broad base  of smaller customers. In particular, the
direct sales force and field application engineers are focused on new design-ins
to enhance the Company's long-term revenue stream.

    Burr-Brown satisfies the majority  of its wafer requirements  (approximately
75%  in 1994) through its own wafer  fabrication facility in Tucson. The Company
is able to  utilize a range  of proprietary bipolar  manufacturing processes  to
optimize   product  performance,   minimize  manufacturing   cost  and  increase
production  flexibility.  The  Company   also  employs  proprietary   deposition
technology and computer-controlled laser trimming techniques to produce circuits
with the desired high precision. The Company augments its internal manufacturing
with wafer foundry and assembly services from third party subcontractors.

    The  Company is also a majority shareholder in two subsidiaries, Intelligent
Instrumentation Inc.,  which  provides  portable  data  collection  systems  and
software   and   signal   conditioning  accessories,   and   Power  Convertibles
Corporation, a supplier of DC-to-DC converter products, and battery chargers for
the cellular telephone market.

                                  RISK FACTORS

    THE FOLLOWING RISK FACTORS SHOULD BE CONSIDERED CAREFULLY IN ADDITION TO THE
OTHER  INFORMATION  CONTAINED IN  THIS PROSPECTUS  BEFORE PURCHASING  THE COMMON
STOCK OFFERED HEREBY.

    POTENTIAL FLUCTUATIONS IN  OPERATING RESULTS.   The Company's quarterly  and
annual  operating results are affected  by a wide variety  of factors that could
materially and adversely affect net sales, gross profit and profitability. These
factors include the volume and timing of orders received, changes in the mix  of
products  sold, market acceptance of the  Company's and its customers' products,
competitive pricing pressures, fluctuations in foreign currency exchange  rates,
the  Company's  ability  to meet  increasing  demand, the  Company's  ability to
introduce  new  products  on  a  timely   basis,  the  timing  of  new   product
introductions  by  the Company  or  its competitors,  the  timing and  extent of
research  and  development  expenses,  fluctuations  in  manufacturing   yields,
semiconductor   industry  cycles,  the  Company's  access  to  advanced  process
technologies,  and  the  timing  and   extent  of  process  development   costs.
Historically,   average  selling  prices  in  the  semiconductor  industry  have
decreased over the  life of  particular products. If  the Company  is unable  to
introduce new products with higher average selling prices or is unable to reduce
manufacturing  costs to offset decreases in the prices of its existing products,
the Company's operating  results will  be adversely affected.  In addition,  the
Company  is limited in  its ability to  reduce costs quickly  in response to any
revenue shortfalls. As a result of the foregoing or other factors, there can  be
no  assurance that the Company will not experience material adverse fluctuations
in future  operating  results on  a  quarterly  or annual  basis.  Although  the
Company's  profits have increased on an annual basis since 1991, there can be no
assurance that the Company  will be able  to maintain or  increase its level  of
profitability  in future periods.  See "Management's Discussion  and Analysis of
Financial Condition and Results of Operations."

    DEPENDENCE ON NEW PRODUCTS.  The Company's success depends upon its  ability
to develop new analog and mixed signal products for existing and new markets, to
introduce such products in a timely manner and to have such products gain market
acceptance.  The development of new products is highly complex, and from time to
time the  Company  has experienced  delays  in developing  and  introducing  new
products. Successful product development and introduction depends on a number of
factors,  including proper new  product definition, timely  completion of design
and testing of new products, achievement of acceptable manufacturing yields, and
market acceptance  of  the  Company's and  its  customers'  products.  Moreover,
successful  product design and development is dependent on the Company's ability
to attract,  retain and  motivate qualified  analog design  engineers, of  which
there  is a limited number.  There can be no assurance  that the Company will be
able to meet these challenges or adjust to changing market conditions as quickly
and cost-effectively as necessary to compete successfully. Due to the complexity
and variety  of products  manufactured by  the Company,  the limited  number  of
analog  circuit designers and the limited effectiveness of computer-aided design
systems in the design  of analog circuits,  there can be  no assurance that  the
Company  will be able  to successfully develop  and introduce new  products on a
timely basis.  Although the  Company  seeks to  design  products that  have  the
potential  to become broadly accepted for high volume applications, there can be
no assurance  that any  products introduced  by the  Company will  achieve  such
market  success. The  Company's failure  to develop  and introduce  new products
successfully could materially  and adversely affect  its business and  operating
results.  The Company has targeted new markets in which it has relatively little
experience, including  the  market  niches for  wireless  applications  for  the
communications   industry,  power  management  applications  for  the  computing
industry, and CD-ROM and PC sound  applications for the digital audio  industry.
There  can be no assurance that the  Company's products will adequately meet the
requirements of such new  markets, or that the  Company's products will  achieve
market acceptance.

    MANUFACTURING  RISKS.   The fabrication of  integrated circuits  is a highly
complex  and   precise  process.   Minute   impurities,  contaminants   in   the
manufacturing  environment, difficulties in the  fabrication process, defects in
the masks used to print circuits  on a wafer, manufacturing equipment  failures,
wafer  breakage or other factors can cause a substantial percentage of wafers to
be rejected or  numerous die  on each wafer  to be  nonfunctional. In  addition,
yields  are  impacted  by  defects  caused during  laser  trimming,  which  is a
difficult process  to manage.  Manufacturing  yields are  also impacted  by  die
handling  and assembly  and test  procedures. A  large portion  of the Company's
manufacturing costs  are  relatively  fixed and,  consequently,  the  number  of
shippable die per wafer for a given product is critical to the Company's results
of operations. To the extent the

                                       5
<PAGE>
Company  does not achieve acceptable manufacturing yields or experiences product
shipment delays,  its financial  condition and  results of  operations would  be
materially  and adversely affected. As is typical in the semiconductor industry,
the Company has  from time to  time experienced lower  than expected  production
yields,  which  have  delayed  product shipments  and  adversely  affected gross
margins. As the Company continues to  increase its manufacturing output and  its
use  of third party foundries,  there can be no  assurance that the Company will
not experience a  decrease in manufacturing  yields. Moreover, there  can be  no
assurance  that the  Company will be  able to  maintain acceptable manufacturing
yields in the future.

    To meet  anticipated  future  demand  and to  utilize  a  broader  range  of
fabrication  processes,  the  Company  intends  to  increase  its  manufacturing
capacity. Failure to  do so could  result in  a loss of  customers, which  could
materially  and adversely affect the Company's financial condition or results of
operations.  However,  given  the  complexity  and  expense  of  designing   and
constructing  a  significant  expansion of  a  semiconductor  fabrication plant,
during the  construction of  the additions  the Company's  manufacturing  yields
could  be materially and adversely impacted. Moreover, there can be no assurance
that the Company will be  able to achieve the goals  of the expansion, that  the
expansion  will be completed  in a timely  manner, or that,  when completed, the
Company's expanded fabrication facility will be capable of producing wafers of a
comparable manufacturing yield and  quality as those  currently produced by  the
Company.

    The  Company  currently manufactures  the majority  of  its products  at its
Tucson wafer fabrication  facility. Given  the complex nature  of the  Company's
products,  it  would be  difficult for  the Company  to arrange  for independent
manufacturing facilities to supply all such products. Any prolonged inability to
utilize the  Company's  manufacturing facility  as  a result  of  fire,  natural
disaster  or otherwise  would have  a material  adverse effect  on the Company's
financial condition and results of operations. As has occurred from time to time
in the past, during  periods of decreased demand,  high fixed wafer  fabrication
costs can result in decreased gross margins and thereby materially and adversely
affect  the Company's financial condition or results of operations. Furthermore,
the  Company  is  dependent  on  a  number  of  foundries  for  certain  of  its
manufacturing  processes not available  internally. The failure  of any of these
foundries to  perform  these  processes  on  a  timely  basis  could  result  in
manufacturing  delays, which could materially and adversely affect the Company's
results of operations.

    RISKS  OF  INTERNATIONAL  SALES.     Sales  to   Japan,  Europe  and   other
international markets in 1992, 1993, 1994 and the six-month period ended July 1,
1995  accounted for  approximately 61%, 64%,  62% and 66%,  respectively, of the
Company's net sales. The Company expects that international sales will  continue
to  represent a majority of net sales. The Company desires to continue to expand
its  operations  outside  of   the  United  States   and  to  enter   additional
international  markets, which will require  significant management attention and
financial resources and subject  the Company further to  the risks of  operating
internationally.   These   risks  include   unexpected  changes   in  regulatory
requirements, delays resulting from difficulty in obtaining export licenses  for
certain technology, tariffs and other barriers and restrictions, and the burdens
of  complying with  a variety of  foreign laws.  The Company is  also subject to
general geopolitical risks in connection with its international operations, such
as political  and  economic instability  and  changes in  diplomatic  and  trade
relationships. The Company cannot predict whether quotas, duties, taxes or other
charges  or restrictions will be imposed by  the United States, Japan, Taiwan or
other countries  upon the  import or  export of  the Company's  products in  the
future,  or what effect any  such actions would have  on its business, financial
condition or results of operations. In  addition, because most of the  Company's
international  sales are denominated in foreign  currencies, gains and losses on
the conversion  to U.S.  dollars  of accounts  receivable and  accounts  payable
arising  from  international operations  may contribute  to fluctuations  in the
Company's operating  results.  In  particular, the  Company's  recent  operating
results  have  been  favorably  impacted  by  fluctuations  in  foreign currency
exchange rates. Although the Company typically enters into hedging  transactions
when  products  are  shipped  in  order  to  reduce  exposure  to  currency rate
fluctuations, there  can be  no assurance  that such  hedging transactions  will
reduce  exposure to currency rate fluctuations  or that fluctuations in currency
exchange rates in the future  will not have an  adverse impact on the  Company's
results  of operations. Furthermore, fluctuations in currency exchange rates may
negatively impact the  Company's ability to  compete in terms  of price  against
products denominated in local currencies. In addition, there can be no assurance
that  regulatory, geopolitical and  other factors will  not adversely impact the
Company's operations in the future or require the Company to modify its  current
business practices.

                                       6
<PAGE>
    COMPETITION.   The  semiconductor industry  is intensely  competitive and is
characterized by  price erosion,  declining gross  margins, rapid  technological
change,  product obsolescence  and heightened international  competition in many
markets.  The  Company's  competitors  include  Analog  Devices,  Inc.,   Linear
Technology Corp., Maxim Integrated Products Inc. and, in some segments, National
Semiconductor  Corporation, Harris Corp., Motorola Inc., Texas Instruments Inc.,
Cirrus Logic Inc., Signal Processing Technologies, Sipex Corp., Unitrode  Corp.,
Asahi  Kasei  Micro, Sony  Electronics  Inc., Hitachi  America  Ltd., Matsushita
Electric Corp. of America, Mitsubishi Corp. and Philips Semiconductors. Many  of
these  competitors have  substantially greater  financial, technical, marketing,
distribution and  other resources,  broader product  lines and  longer  standing
relationships  with customers than  the Company. The  Company's competitors also
include emerging companies  attempting to sell  products to specialized  markets
such as those addressed by the Company. In the event of a downturn in the market
for  analog  circuits,  companies that  have  broader product  lines  and longer
standing customer relationships may be  in a stronger competitive position  than
the  Company. Competitors  with greater  financial resources  or broader product
lines also may have more resources than the Company to engage in sustained price
reductions in the Company's primary markets to gain market share. As is  typical
in  the semiconductor  industry, competitors of  the Company  have developed and
marketed products having similar  or identical design  and functionality as  the
Company's  products,  and the  Company expects  that this  will continue  in the
future. To the extent the Company's products do not achieve performance, size or
other advantages over products offered by competitors, the Company is likely  to
experience greater price competition with respect to such products.

    The  Company believes that its ability  to compete successfully depends on a
number of  factors both  within and  outside of  its control,  including  price,
product  quality, performance, success in  developing and timing of introduction
of new  products,  adequate  wafer  fabrication  capacity  and  sources  of  raw
materials,  efficiency  of production,  timing of  new product  introductions by
competitors,  protection  of  Company  products  by  effective  utilization   of
intellectual  property laws, and  general market and  economic conditions. There
can be no assurance that the Company will be able to compete successfully in the
future.

    TECHNOLOGICAL  CHANGE.    The  markets   for  the  Company's  products   are
characterized   by  rapid   technological  change   and  frequent   new  product
introductions. To remain competitive, the Company must develop or obtain  access
to  new  semiconductor  design  and process  technologies  to  reduce  die size,
increase die  performance and  functional complexity  and improve  manufacturing
yields.  Semiconductor  design and  process methodologies  are subject  to rapid
technological change, requiring large expenditures for research and development.
If the  Company  is  unable  to  develop or  obtain  access  to  advanced  wafer
processing  technologies as they become needed,  or is unable to define, design,
develop and introduce  competitive new products  on a timely  basis, its  future
operating  results will be  materially and adversely  affected. In addition, the
Company's ability to compete successfully depends on being able to use  advanced
analog  process  technologies  to  manufacture its  products.  There  can  be no
assurance that the analog process technologies utilized by the Company will  not
become obsolete.

    SEMICONDUCTOR  INDUSTRY.   The semiconductor industry  has historically been
cyclical and subject to significant economic downturns at various times, and has
been characterized from time to  time by diminished product demand,  accelerated
erosion of average selling prices and overcapacity. In addition, the end-markets
for systems that incorporate the Company's products are characterized by rapidly
changing  technology and evolving industry standards. Although the semiconductor
industry in  recent  periods has  experienced  increased demand  and  production
capacity  constraints, it is uncertain how  long these conditions will continue.
The Company  also may  experience substantial  period-to-period fluctuations  in
future  operating  results  due to  general  semiconductor  industry conditions,
overall  economic  conditions  or  other   factors.  The  Company,  like   other
semiconductor  manufacturers with  fabrication facilities, has  high fixed costs
for its manufacturing facilities and believes that its operating results may  be
adversely   affected   by  an   industry-wide   downturn  in   the   demand  for
semiconductors. Such downturns may coincide with a recession in the U.S. economy
and slower  growth  in  various  electronics  industries  using  semiconductors,
including market segments in which the Company is engaged at the time.

    DEPENDENCE  ON  KEY  EMPLOYEES; NEED  TO  HIRE  AND RETAIN  PERSONNEL.   The
Company's future  performance depends  in significant  part upon  the  continued
service  of its key technical  and senior management personnel.  The loss of the
services of one or more of the  Company's officers or other key employees  could
have  a material adverse effect on the Company's business, operating results and
financial condition. While many of the

                                       7
<PAGE>
Company's current employees have many years  of service with the Company,  there
can  be  no assurance  that  the Company  will be  able  to retain  its existing
personnel. If the Company is unable to retain and hire additional personnel, the
Company's business and results of  operations could be materially and  adversely
affected.  The  future success  of the  Company  is dependent,  in part,  on its
ability to attract,  assimilate and  retain additional,  including certain  key,
personnel.  The Company will continue to need a substantial number of personnel,
including those  with  specialized skills,  to  commercialize its  products  and
expand  all areas  of its  business in  order to  continue to  grow. The Company
intends to hire a significant number of additional personnel in 1995 and beyond.
Competition for such personnel  is intense, and there  can be no assurance  that
the  Company will  be able  to attract,  assimilate or  retain additional highly
qualified personnel.

    DEPENDENCE ON KEY SUPPLIERS.   The Company  has integrated circuit  assembly
operations  in Tucson and Scotland. In addition,  much of the assembly demand is
met by using contract  assembly companies located in  the United States,  Japan,
Taiwan,  Malaysia,  Korea and  the Philippines.  In  the event  that any  of the
Company's contract assembly companies were to experience financial, operational,
production or  quality  assurance  difficulties  resulting  in  a  reduction  or
interruption  in supply to the Company, the Company's operating results would be
adversely affected until alternate contract  assembly companies, if any,  became
available. The principal raw materials used by the Company in the manufacture of
its  monolithic integrated circuits are silicon wafers, chemicals and gases used
in processing  wafers, gold  wire and  ceramic, metal  and epoxy  packages  that
enclose  the chip and provide the  external connections for the circuit. Silicon
wafers and other raw materials may be obtained from several suppliers. From time
to time, particularly during periods of increased industry-wide demand,  silicon
wafers  and other materials have been in  short supply. A prolonged inability to
obtain silicon wafers or any other  raw materials could have a material  adverse
impact on the Company's business.

    PATENTS AND INTELLECTUAL PROPERTY.  The Company's success depends in part on
its  ability to obtain  patents and licenses and  to preserve other intellectual
property rights covering its  manufacturing processes, products and  development
and  testing tools. The Company seeks patent protection for those inventions and
technologies for which it believes such protection is suitable and is likely  to
provide  a competitive advantage to the Company. The Company currently holds 106
United  States  patents  on  semiconductor  devices  and  methods  with  various
expiration  dates, some  as early  as 1995. The  Company has  applications for 6
United States  patents currently  pending.  The Company  also holds  36  foreign
patents  and has 34 foreign patent  applications pending. The process of seeking
patent protection can be long and expensive  and there can be no assurance  that
its  current patents or any new patents that may be issued will be of sufficient
scope or  strength  to  provide  any meaningful  protection  or  any  commercial
advantage  to  the Company.  The  Company may  in the  future  be subject  to or
initiate interference  proceedings in  the United  States Patent  and  Trademark
office, which can demand significant financial and management resources.

    The  Company regards elements  of its manufacturing  process, product design
and equipment as proprietary and seeks to protect its proprietary rights through
a combination of  employee and third  party non-disclosure agreements,  internal
procedures  and  patent protection.  Notwithstanding  the Company's  attempts to
protect its proprietary  rights, the  Company believes that  its future  success
will  depend  primarily  upon  the  technical  expertise,  creative  skills  and
management abilities of its officers and key employees rather than on patent and
copyright ownership. The Company also relies substantially on trade secrets  and
proprietary  technology to  protect technology  and manufacturing  know-how, and
works actively to  foster continuing  technological innovation  to maintain  and
protect  its competitive position. There can  be no assurance that the Company's
competitors will not independently develop or patent substantially equivalent or
superior technologies.

    The semiconductor industry is characterized by frequent litigation regarding
patent and other intellectual  property rights. There can  be no assurance  that
any  patent  owned  by the  Company  will  not be  invalidated,  circumvented or
challenged,  that  the  rights  granted  thereunder  will  provide   competitive
advantages  to the Company or that any of the Company's pending or future patent
applications will be issued with the scope of the claims sought by the  Company,
if  at all. In addition, effective copyright  and trade secret protection may be
unavailable or limited in certain foreign countries. The Company is currently  a
plaintiff  in  certain  litigation  regarding  improper  use  of  the  Company's
proprietary information. A counter-claim has  been filed against the Company  in
connection  with such  litigation. In  addition, the  Company has  been sued for
patent infringement by a competitor.  While the claimed infringement relates  to
products    that    account   for    an    immaterial   level    of    its   net

                                       8
<PAGE>
sales and the Company believes it  has meritorious defenses to these claims  and
the counter-claim, patent litigation is inherently uncertain and there can be no
assurance that these matters or future intellectual property litigation will not
have a material adverse impact on the Company's business.

    As  is typical in the  semiconductor industry, the Company  has from time to
time received, and may in the future receive, communications from third  parties
asserting  patents, maskwork rights,  or copyrights on  certain of the Company's
products and technologies.  In the  event a  third party  were to  make a  valid
intellectual  property claim  and a  license was  not available  on commercially
reasonable terms,  the  Company's  operating results  could  be  materially  and
adversely  affected. Litigation, which  could result in  substantial cost to the
Company and diversion of its resources, may also be necessary to enforce patents
or other intellectual property  rights of the Company  or to defend the  Company
against  claimed infringement  of the  rights of  others. The  failure to obtain
necessary  licenses  or  the  occurrence   of  litigation  relating  to   patent
infringement  or  other  intellectual  property matters  could  have  a material
adverse effect on the Company's business and operating results. There can be  no
assurance  that  the steps  taken  by the  Company  to protect  its intellectual
property will be adequate  to prevent misappropriation or  that others will  not
develop competitive technologies or products.

    ENVIRONMENTAL  AND OTHER GOVERNMENTAL REGULATIONS.  Federal, state and local
regulations impose  various controls  on the  storage, handling,  discharge  and
disposal  of chemicals and gases used in the Company's manufacturing process and
on the facility leased by the Company. The Company believes that its  activities
conform to present governmental regulations applicable to its operations and its
current  facilities, including those related  to environmental, land use, public
utility utilization  and fire  code matters.  Increasing public  attention  has,
however,  been focused on  the environmental impact  of semiconductor operations
and the risk to neighbors of  chemical releases from such operations. There  can
be  no assurance that  future governmental regulations will  not impose the need
for additional capital equipment or other process requirements upon the  Company
or  restrict the  Company's ability  to expand  its operations.  The adoption of
future regulations  or any  failure by  the Company  to comply  with  applicable
existing  environmental and land use regulations or to restrict the discharge of
hazardous substances could  subject the  Company to future  liability and  could
cause its manufacturing operations to be curtailed or suspended.

    The  Company is  a named  party in a  toxic tort  case filed  in Pima County
Superior Court on January 13, 1992. The Company attempted informal  negotiations
with  the  plaintiffs  for  dismissal  that  were  ultimately  unsuccessful.  On
September 29,  1993, the  Company then  answered and  denied liability  for  the
nuisance,  trespass, negligence, strict liability,  and other alleged torts. The
Company is named in three other toxic tort cases filed in U.S. District Court on
September 20, 1991, August 7, 1992, and January 9, 1995, respectively, which are
consolidations of  individual lawsuits  that  sought damages  for  contaminating
ground  water which was then pumped from public wells and consumed. Injuries are
alleged to have resulted  from drinking the contaminated  water and one suit  is
asking  for future medical monitoring. Third  party complaints were filed by the
original defendant against five companies including Burr-Brown on September  30,
1993,  March 7,  1994, and February  16, 1995.  The complaints seek  to have the
other five  companies  share  in  whatever damages  are  imposed.  The  original
defendant/third  party claimant  and the  Company have  filed joint  motions for
dismissal of all claims against Burr-Brown without prejudice on the three  cases
filed in U.S. District Court, and are awaiting approval of the court.

    After  undertaking  extensive hydrological  investigations  and consultation
with independent  environmental consultants,  the Company  believes it  did  not
contribute  to the alleged contamination and,  therefore, is of the opinion that
the disposition of the claims in the four toxic tort cases described above  will
not  result in any material change in the Company's financial condition, results
of operations  or liquidity.  However,  environmental litigation  is  inherently
uncertain,  and there can  be no assurance  as to the  ultimate outcome of these
claims.

    CONTROL BY OFFICERS, DIRECTORS AND AFFILIATED ENTITIES.  Upon completion  of
this offering, Thomas R. Brown,
Jr.   and  the  Company's  other  directors,  executive  officers  and  entities
affiliated with such directors  as a group  will beneficially own  approximately
37.4%  and  2.8%, respectively,  of  the issued  and  outstanding shares  of the
Company's Common  Stock. Accordingly,  such  stockholders will  have  sufficient
voting  power  to control  the  outcome of  matters  (including the  election of
directors and any merger, consolidation or  sale of all or substantially all  of
the  Company's assets)  submitted to  the stockholders  for approval  and may be
deemed to have

                                       9
<PAGE>
effective  control  over  the  affairs  and  management  of  the  Company.  This
controlling  interest in the Company may also  have the effect of making certain
transactions  more  difficult  or  impossible,   absent  the  support  of   such
stockholders. Such transactions could include a proxy contest, mergers involving
the  Company, tender offers  and open market  purchase programs involving Common
Stock that could give stockholders of  the Company the opportunity to realize  a
premium over the then prevailing market price for their shares of Common Stock.

    STOCK PRICE VOLATILITY.  The trading price of the Company's Common Stock may
be  subject to wide fluctuations in response to quarter-to-quarter variations in
operating results, announcements of technological innovations or new products by
the Company  or its  competitors, general  conditions in  the semiconductor  and
electronic   components   industries,   changes   in   earnings   estimates   or
recommendations by analysts, or other events or factors. In future quarters,  if
the  Company's financial  performance falls  below the  performance predicted by
securities analysts, the Company's stock  price could decline. In addition,  the
public   stock  markets  have  experienced  extreme  price  and  trading  volume
volatility in  recent months.  This volatility  has significantly  affected  the
market  prices  of  securities of  many  high technology  companies  for reasons
frequently unrelated to  the operating  performance of  the specific  companies.
These  broad market  fluctuations may adversely  affect the market  price of the
Company's Common Stock.

    EFFECT OF  ANTI-TAKEOVER PROVISIONS.   The  Company has  taken a  number  of
actions that could have the effect of discouraging a takeover attempt that might
be  beneficial to stockholders  who wish to  receive a premium  for their shares
from a potential bidder. The Company has adopted a stockholder rights plan  that
would cause substantial dilution to a person who attempts to acquire the Company
on  terms  not approved  by the  Company's Board  of Directors.  The stockholder
rights plan may therefore have the  effect of delaying or preventing any  change
in  control  and  deterring  any  prospective  acquisition  of  the  Company. In
addition, the  Company's  Certificate  of  Incorporation  grants  the  Board  of
Directors  the authority to issue up to  2,000,000 shares of Preferred Stock and
to determine  the price,  rights,  preferences and  privileges of  those  shares
without  any further vote or action by the Company's stockholders. The rights of
the holders of Common Stock  will be subject to,  and may be adversely  affected
by,  the rights  of the  holders of any  shares of  Preferred Stock  that may be
issued in the future. While the Company has no present intention to issue shares
of Preferred  Stock, such  issuance, while  providing desirable  flexibility  in
connection  with possible acquisitions and  other corporate purposes, could have
the effect of making it more difficult  or less attractive for a third party  to
acquire  a  majority  of  the  outstanding voting  stock  of  the  Company. Such
Preferred Stock may also have other rights, including economic rights senior  to
the  Common Stock, and, as a result,  the issuance thereof could have a material
adverse  effect  on  the  market  value  of  the  Common  Stock.  The  Company's
Certificate  of  Incorporation  also  contains  a  "fair  price"  provision that
requires the approval of the holders of 90% of the Company's outstanding  voting
shares  as a condition to a merger or other "business combination" involving the
Company and any "related person," unless  the transaction is either approved  by
at  least a two-thirds vote of  disinterested directors or certain minimum price
and procedural requirements are met. Furthermore, the Company is subject to  the
anti-takeover provisions of Section 203 of the Delaware General Corporation Law,
which  prohibits the Company  from engaging in a  "business combination" with an
"interested stockholder"  for a  period of  three years  after the  date of  the
transaction  in  which the  person  first becomes  an  "interested stockholder,"
unless the  business  combination  is  approved  in  a  prescribed  manner.  The
application  of Section 203 also could have the effect of delaying or preventing
a change of control of the Company.

                                  THE COMPANY

    Burr-Brown Corporation ("Burr-Brown" or  the "Company") was incorporated  in
Arizona  in May 1956 as "Burr-Brown Research Corporation" and was reincorporated
in Delaware in January 1983 as "Burr-Brown Corporation." The Company's executive
offices are located at 6730 South  Tucson Boulevard, Tucson, Arizona 85706,  and
the Company's telephone number is (520) 746-1111.

    The  name "Burr-Brown"  and the  logo appearing  on the  cover page  of this
Prospectus are  registered  trademarks of  the  Company in  the  United  States.
"Intelligent  Instrumentation  Inc."  and "Power  Convertibles  Corporation" are
registered trademarks  of such  corporations. Trademarks  of corporations  other
than the Company are also referred to in this Prospectus.

                                USE OF PROCEEDS

    The  net proceeds to  the Company from  the sale of  the 1,750,000 shares of
Common Stock offered by the Company  hereby at an assumed public offering  price
of  $32.00  per  share  are  estimated to  be  $52,950,000  ($60,930,000  if the
Underwriters' over-allotment option is exercised in full).

    The Company intends to use the net proceeds for capital expenditures for the
expansion of manufacturing  capacity and general  corporate purposes,  including
working  capital. The Company anticipates that  its capital expenditures in 1995
and 1996 will aggregate approximately $80 million. Proceeds may also be used  to
acquire  companies,  products  or  technologies  that  complement  the Company's
business should such  opportunities arise.  No specific  acquisitions are  being
planned  or negotiated as of the date of this Prospectus. Pending such uses, the
net proceeds  will be  temporarily invested  in short-term  obligations such  as
certificates of deposit issued by banks, government obligations and money market
securities.

</TABLE>

    NET SALES.   Net  sales increased  over  the past  six quarters  from  $47.4
million  in the first quarter of 1994 to  $69.6 million in the second quarter of
1995. This increase, which primarily occurred in the first two quarters of 1995,
reflects  continued  sales  of  the   Company's  products  into  the  test   and
instrumentation  market  and  the  industrial and  process  control  market, and
increased sales into  the higher  growth communications,  computing and  digital
audio  markets. In addition, sales of the Company's products in Japan and Europe
increased as a percentage of total sales over these periods. The increase in the
Company's net sales also reflects  the performance of the overall  semiconductor
industry,  a favorable pricing  environment for the  Company's products, and the
favorable impact of changes in foreign currency exchange rates, particularly for
the Japanese Yen and the German Mark. Although unit volumes generally  increased
throughout  the four quarters of 1994,  average selling prices declined over the
period, primarily due to changes in product mix, contributing to the  relatively
slow  sequential growth in 1994.  Sales growth accelerated in  the first half of
1995 due  to accelerated  unit volumes  and modestly  increased average  selling
prices.

    GROSS PROFIT.  The Company's gross margins decreased from 48.3% in the first
quarter  of  1994  to  42.2%  in  the  fourth  quarter  of  1994.  Gross margins
subsequently increased to 47.3%  and 48.6% in the  first and second quarters  of
1995,  respectively.  The decreased  gross margins  in the  second half  of 1994
reflect, in part,  the Company's efforts  to manage its  inventory levels  while
continuing to increase its net sales. These inventory management efforts reduced
assembly  and test manufacture cycle times, which caused an overall reduction in
work in process  and finished goods  inventories. The combined  effect of  these
inventory  management practices allowed  the Company to  increase net sales over
the remainder of 1994 while decreasing manufacturing volumes during this period.
As a result, the  Company's fixed manufacturing costs  were allocated against  a
relatively smaller amount of manufactured goods in the third and fourth quarters
of  1994, resulting in  lower gross margins during  those periods. The Company's
gross margins  have  returned  to the  levels  of  the first  half  of  1994  as
manufacturing volumes have increased to meet increasing net sales.

    PRODUCT  DEVELOPMENT.    Product development  expenses  increased  from $4.9
million to $6.9  million over the  past six quarters  while fluctuating  between
approximately  10% and 12% of net sales over the period. The Company's long-term
strategy is to increase this spending level,  both in absolute dollars and as  a
percentage  of net sales. During the first half of 1995, the Company established
a separate technology development department  focused on process development  in
order to assist in this critical area.

                                       15
<PAGE>
    SELLING,  GENERAL AND  ADMINISTRATIVE.  Selling,  general and administrative
expense remained relatively constant between $13.5 million and $14.6 million  in
1994,  while increasing  to $15.6  million and  $16.8 million  in the  first and
second quarters  of 1995,  respectively. As  a percentage  of net  sales,  these
expense  items have generally decreased from 30.8%  in the first quarter of 1994
to 24.2% in the second quarter of  1995, largely reflecting the increase in  net
sales.  Part of  the percentage decrease  in the  first half of  1995 reflects a
consolidation of marketing resources  in Europe and an  overall increase in  the
percentage  of sales  made through  independent distributors  rather than direct
sales.

    NET INCOME.  Net income has ranged  between 2.1% and 9.8% of net sales  over
the  past  six  quarters,  generally  reflecting  the  combined  effect  of  the
above-described variables. The tax  rates over this  period have been  favorably
impacted  by  the expected  utilization  of net  operating  loss and  tax credit
carryforwards as well as  a greater increase in  United States profits than  the
increase  in profits from foreign operations, which have higher income tax rates
than the United States.

                                    BUSINESS

    Burr-Brown  is a leader in the  design, development, manufacture and sale of
high performance  analog and  mixed signal  integrated circuits.  The  Company's
products  are  used  in  a variety  of  electronic  systems  for communications,
computing, industrial process control,  test and instrumentation, digital  audio
and  imaging.  The  Company offers  over  1,000 high  performance  products that
perform signal processing functions such as the conditioning, amplification  and
filtering   of   analog   signals,   and   mixed   signal   functions   such  as
analog-to-digital and digital-to-analog conversion. Within its targeted markets,
Burr-Brown emphasizes  high  performance  applications where  its  products  are
critical elements of complex systems.

INDUSTRY BACKGROUND

    Integrated  circuits may  be divided into  three categories--analog, digital
and  mixed  signal.   Digital  circuits,  which   include  memory  devices   and
microprocessors,  use many repetitive  circuit elements that  can each represent
the two values ("1" and "0") required by the binary number system that serves as
a basis for most computation. Analog circuits, on the other hand, are capable of
representing infinite  numbers of  values,  with an  output  signal based  on  a
continuously varying input signal. These input signals typically represent "real
world"  phenomena such as temperature,  pressure, position, frequency, sound and
speed. Mixed signal circuits  are circuits that employ  both analog and  digital
signal  processing techniques. Analog and mixed signal circuits are used in most
electronic systems, with  major markets for  such circuits including  computing,
telecommunications  and  data  communications,  test  and  measurement,  medical
instrumentation, industrial process  control, manufacturing automation,  digital
audio  and  automotive  electronics.  Typical  analog  circuits  include  signal
amplifiers, instrumentation amplifiers, current transmitters, regulators, analog
multipliers and  isolation amplifiers.  Typical  mixed signal  circuits  include
analog-to-digital  and digital-to-analog converters.  Recently, the rapid growth
of  the  high  speed  and  wireless  communications,  multimedia  and   portable
computing,   and  digital  audio  markets  have  created  important  new  growth
opportunities for high  performance analog and  mixed signal products.  Industry
sources  estimate that analog and mixed signal  circuits will account for 14% of
the projected $125 billion market for semiconductors in 1995.

    The market for, and  design and production of,  analog circuits differ  from
the  market  for, and  design  and production  of,  digital circuits  in several
important ways. In general, the market for analog circuits is more diverse  than
for  digital  circuits,  with  each  application  requiring  different operating
specifications for resolution, processing linearity, speed, power and  amplitude
capability.  As  a result,  analog  circuits generally  have  relatively smaller
volume requirements per device.  The markets for  analog circuits are  generally
fragmented, and competition within those markets tends to depend less upon price
and  more  upon  performance,  functionality,  quality  and  reliability. Analog
circuits designed for  specific applications are  often characterized by  longer
life  cycles  and  more stable  pricing  compared to  typical  digital circuits.
Computer-aided  design  and  engineering  tools,  which  have  proliferated  and
enhanced  the design effort for digital  integrated circuits, are less effective
for analog devices.  Accordingly, analog circuit  design has traditionally  been
highly  dependent on the  skills and experience  of individual design engineers.
Also, in contrast  to digital circuits,  the performance of  analog circuits  is
more  dependent on  circuit design, circuit  layout and the  matching of circuit
elements than  on advanced  capabilities in  submicron manufacturing  processes.
Consequently,  the  production  of high  performance  analog  circuits typically
requires less  capital  investment  than the  production  of  highly  integrated
digital  circuits. Because analog circuits are found in most electronic systems,
the growth in the use  of digital systems across  a broad range of  applications
has in turn fueled a growth in the demand for analog integrated circuits.

<PAGE>
application specific standard products (ASSPs) that are developed to address the
unique requirements of  fast growing emerging  applications. Beginning in  1994,
Burr-Brown's  new  management team  developed a  plan  to enhance  the Company's
growth and profitability by employing the following strategies:

    STRENGTHEN LEADERSHIP IN THE COMPANY'S TRADITIONAL MARKETS.  Burr-Brown is a
leading  supplier  of  precision  high  performance  analog  and  mixed   signal
integrated  circuits to a  variety of markets,  including the industrial process
control, and  test  and instrumentation  markets,  and offers  over  1,000  high
performance  products to a  diverse base of over  30,000 customers worldwide. In
these markets, the  Company has  maintained long-term  relationships with  major
customers and typically serves as the sole supplier of proprietary products. The
Company  intends to enhance its leadership  position and expand its market share
in the design, manufacture and marketing of these products by offering optimized
standard products along with targeted high volume application-specific  standard
products.  The  Company  believes  that its  established  reputation  and strong
customer  relationships  will  continue  to   facilitate  entry  into  key   new
applications which include smart sensors and AC motor control.

    TARGET  HIGH  GROWTH MARKETS.    The Company  is  expanding its  presence in
certain high growth segments of the communications, computing, digital audio and
imaging markets in  which it can  capitalize on its  expertise in designing  and
manufacturing precision analog and mixed signal integrated circuits. The Company
seeks  to increase its presence in these markets by leveraging its existing core
competencies and understanding of customer needs into key market niches such  as
wireless basestations and High bit rate Digital Subscriber Line ("HDSL") for the
communications  market;  and  power  management,  CD-ROM,  PC-sound  and imaging
applications for the computing market.  Within its targeted markets,  Burr-Brown
emphasizes  high  performance  applications  where  its  products  are  critical
elements of complex systems.

    ACCELERATE  NEW  PRODUCT   DEVELOPMENT.    To   capitalize  on  the   growth
opportunities  in its targeted markets, the  Company seeks to expand its product
offerings while reducing  the time  required to  bring new  products to  market.
Since the beginning of 1994, the Company has introduced over 90 high performance
products,  including a  family of  low power,  high resolution analog-to-digital
converters for a broad range of applications; a group of high speed  operational
amplifiers delivering low noise and low distortion necessary for applications in
video  signal  processing and  high speed  communications;  a portfolio  of high
precision instrumentation  amplifiers that  offer leading  edge performance  for
applications  in  process control,  and test  and  measurement; and  several PCM
digital-to-analog converters  well-suited  for  multimedia,  CD-ROMs,  cable  TV
set-top   boxes,  video  phones   and  other  high   performance  digital  audio
applications.

    LEVERAGE WORLDWIDE SALES AND  DISTRIBUTION NETWORK.   The Company sells  its
products  in major markets  worldwide through an  approximately 75 person direct
sales force, 40 manufacturers' representatives and 20 distributors. The  Company
has  recently  reorganized  its  worldwide  sales  and  distribution  network by
focusing its direct sales force on large corporate customers while directing its
distributors to  service the  Company's  broad base  of smaller  customers.  The
Company believes this organizational realignment will increase the efficiency of
its selling efforts. In particular, the direct sales force and field application
engineers  are  focused on  new design-ins  to  enhance the  Company's long-term
revenue stream.

    IMPROVE COST CONTROLS.   The  Company is  implementing an  organization-wide
cost  reduction  program  to  increase product  margins  and  profitability. The
Company seeks to improve manufacturing  yields, reduce cycle times and  increase
direct  labor productivity, thereby increasing  manufacturing output and gaining
additional operating leverage  from fixed  manufacturing costs.  The Company  is
making  significant  investments in  more  advanced wafer  fabrication  and test
equipment to  support  these efforts.  Additionally,  the Company  is  migrating
labor-intensive  assembly  and test  operations  from higher  cost  domestic and
Japanese facilities to  more cost-effective Southeast  Asian locations.  Expense
growth  is  being  constrained  within the  sales,  marketing,  and  general and
administrative areas to improve operating margins as sales increase. As part  of
this  initiative,  the  Company  is working  to  improve  its  infrastructure by
investing in  a fully  integrated management  information system  that will  tie
together  sales and  distribution, finance and  materials management, production
planning, and  shop floor  control functions.  The Company  believes that,  once
completely  implemented, the system will  facilitate further cost reductions and
create improved organizational efficiencies.

    EMPLOY INTERNAL  AND  EXTERNAL MANUFACTURING.    The Company  believes  that
employing  both internal  and external manufacturing  capacity improves quality,
cost-effectiveness, responsiveness to customers, access to capacity, ability  to
implement  leading  edge  process technology  and  time to  market.  The Company
produces a majority of its wafers  at its bipolar wafer fabrication facility  in
Tucson,  Arizona and augments  internal manufacturing capacity  with the foundry
services of  third  party  wafer  subcontractors  for  processes  not  available
internally.  These third party processes include  CMOS, BiCMOS and other bipolar
processes. Because  the  semiconductor  industry is  currently  facing  capacity
constraints in wafer manufacturing and the availability of third party foundries
has  diminished  significantly, the  Company plans  to expand  significantly and
upgrade its Tucson wafer fabrication facility while simultaneously continuing to
use third party foundries for the manufacture of certain products.

    There  can  be  no  assurance   that  the  Company's  strategies,  even   if
successfully  implemented, will reduce  the risks associated  with the Company's
business. See "Risk Factors."

     LINEAR PRODUCTS DIVISION

    The  Company's  analog  circuits   include  operational  amplifiers,   power
amplifiers,  instrumentation amplifiers, programmable gain amplifiers, isolation
amplifiers, current transmitters and other analog signal processing  components.
Analog  signal processing integrated  circuits are used  to process and transmit
analog  information  prior  to  their  conversion  to  digital  signals.   These
components  are  used  in communications  equipment,  automatic  test equipment,
analytical instruments,  medical instruments  and systems,  military  equipment,
industrial controls, personal computing devices and computer peripherals.

                                       20

        OPERATIONAL  AMPLIFIERS.  Operational amplifiers  are used to detect and
    amplify weak (low level) analog signals and are included in many measurement
    and control systems. The operational  amplifier is the fundamental  building
    block in analog systems design. In addition to amplification, it can perform
    mathematical   functions  such  as   integration  and  differentiation.  The
    Company's high performance operational  amplifiers are generally capable  of
    amplifying  typical analog  signals in  the micro-volt  range up  to 100,000
    times and  provide  ultra-low  drift,  low bias  current,  low  noise,  high
    bandwidth  and fast settling  time. Certain models  provide high voltage and
    high current  operation for  special  applications. These  high  performance
    amplifiers are required to treat signals generated in numerous applications,
    including  scramblers for  satellite communications  systems, robotic vision
    systems and  magnetic resonance  and  computer-aided tomography  (CAT)  body
    scanning systems.

        OTHER   AMPLIFIERS.    The  Company   manufactures  a  number  of  other
    amplifiers,  including  instrumentation  amplifiers  and  programmable  gain
    amplifiers.  These products  perform a variety  of functions  related to the
    amplification of analog signals. Among  other uses, these components  permit
    the  measurement of  weak signals  in the  presence of  unwanted "noise" and
    protect sensitive instruments from the effects of transient  high-magnitude,
    potentially  damaging  voltages  caused  by  sources  such  as  lightning or
    switching of  high voltage  equipment.  These amplifiers  are used  in  many
    diverse  applications  ranging  from temperature  measurement  in industrial
    processes to the protection of sensitive medical instruments, and to isolate
    electrical power line disturbances and faults.

        OTHER  SIGNAL  PROCESSING  AND  TRANSMITTER  COMPONENTS.    The  Company
    manufactures   a  variety  of  other  analog  signal  processing  components
    including  mathematical   function   circuits,  current   transmitters   and
    voltage-to-frequency  converters.  Mathematical function  circuits  are used
    when  information  sought  can  be  effectively  derived  only  through  its
    mathematical  relationship  to  analog  signals.  Current  transmitters send
    analog signal information from  a process sensor  to measurement or  control
    equipment  in the form of a current on the same wires that produce the power
    to the  transmitter  and  sensor.  Voltage-to-frequency  converters  convert
    process signals to a frequency, making the signal immune to electrical noise
    and permitting more efficient storage and processing of the information.

    DATA CONVERSION PRODUCTS DIVISION

    The  Company's  Data Conversion  Products  Division focuses  on  the design,
manufacturing and marketing of integrated circuit devices used to convert analog
signals to digital  form ("A/D  converters") or  to convert  digital signals  to
analog  form ("D/A converters").  This conversion is  necessary in virtually all
applications in which digital  computers or processors  measure and control  the
analog signals from a physical, "real world" process.

        GENERAL  PURPOSE  CONVERSION PRODUCTS.   The  majority of  the Company's
    mixed signal  components  revenue  is  derived  from  moderate  speed,  high
    resolution  and high  accuracy converters. These  general purpose converters
    are  used  primarily  in  manufacturing  process  control   instrumentation,
    electronic  test instrumentation, automatic  test systems and communications
    systems. For example, in a robot  controller, the position of the robot  arm
    must  be precisely measured and manipulated. Analog signals from the robot's
    position sensors are converted by  an A/D converter for computer  processing
    and,  in turn, a D/A converter converts  the digital control signal from the
    computer to analog form to drive the actuators and servo motors to  position
    the robot arm accurately.

        HIGH  SPEED CONVERSION PRODUCTS.  In the early 1980's, the Company began
    developing high  speed, high  resolution A/D  and D/A  converters at  speeds
    substantially  greater than general purpose products. These products utilize
    a unique  combination  of  technologies  and  design  expertise  to  achieve
    state-of-the-art performance. High speed converters are used in a variety of
    applications  such as  image processing,  digital oscilloscopes, ultrasound,
    radar and sonar, as well as the front end of advanced systems using  digital
    signal  processing (DSP)  technology. The Company  believes that  due to the
    unique combination of technologies involved, the high speed, high resolution
    data converter products have limited competition.

    DIGITAL AUDIO PRODUCTS DIVISION (BURR-BROWN JAPAN)

    The Company's  Digital Audio  Products Division,  which is  operated by  the
Company's wholly-owned Japanese subsidiary, focuses on the design, manufacturing
and marketing of high precision, single chip digital-

                                       21
<PAGE>
to-analog  converters and  analog-to-digital for  the digital  audio market. The
Company believes  that Burr-Brown  was the  first company  to introduce  such  a
product  into  this marketplace  and is  currently one  of the  largest merchant
market suppliers of such devices worldwide. This product, a pulse-code-modulated
("PCM") conversion device,  plays an  essential role in  digital audio  systems,
such  as  compact disc  ("CD")  players, that  use  laser technology  to achieve
improved audio reproduction  performance. The Company's  component converts  the
digital  signals  for each  stereo channel  into  audio. Several  generations of
products of this  type have  been developed and  introduced for  use in  digital
audio  systems. Involvement  in the  CD market  also helped  the Company's early
entry into the digital  audio tape ("DAT") and  multimedia markets. The  Company
believes  that  the technology  developed for  its  digital audio  D/A converter
products enables the Company to develop products for other markets. Burr-Brown's
PCM converters have now been designed into musical instruments, computer  games,
automobile  sound systems, CD-ROMs  for multimedia applications  and set top box
tuners for cable and satellite TV.

    ISOLATION PRODUCTS DIVISION (BURR-BROWN LTD.)

    The Company's Isolation Products Division, which is operated by Burr-Brown's
wholly-owned  Scottish   subsidiary,  focuses   on  the   design,   development,
manufacturing,  and marketing  of isolation amplifiers,  isolated analog digital
converters, bus transceivers,  and DC-to-DC converters.  These products  provide
galvanic  isolation  of input  and output  signals  and thereby  achieve reduced
circuit noise interference and prevent harm  to people or equipment due to  high
voltage  transients  or  current  leakage. The  product  line  utilizes optical,
tranformer, and  capacitive  techniques  to produce  linear  transfer  functions
between  input and  output. In certain  products, isolated  digital couplers are
used in lieu  of opto-couplers in  the galvanic isolation  of data signals.  The
isolation products are used in industrial process control, communication, and in
medical instrumentation.

INTELLIGENT INSTRUMENTATION INC. (III)

    Intelligent  Instrumentation Inc. designs, manufactures  and markets a broad
line of  data  acquisition products,  including  plug-in boards,  portable  data
acquisition  systems, microterminals and  supporting software for IBM-compatible
PCs, as well as signal conditioning accessories for such systems. These products
are applied worldwide for a wide range of industrial and scientific applications
such as  inventory  control, package  tracking,  image pattern  recognition  and
electro-medical  systems. A key part of the data acquisition product line is the
Visual Designer-TM- software, a graphical development environment which  enables
users to design applications by connecting functional blocks, called icons, in a
flow  diagram. III also offers integrated  data collection systems that not only
collect data,  but format  and deliver  that data  to a  customer's  information
system  in real time.  Representative customers include  Mercedes Benz, Siemens,
Nikon Koden, Novellus Systems and Xerox.

POWER CONVERTIBLES CORPORATION (PCC)

    Power Convertibles Corporation focuses on the market for DC-to-DC conversion
and battery chargers. PCC  is one of  the leading suppliers  of low power  DC/DC
converters  as well as products to condition  and charge many types of batteries
including cellular  telephones.  Its  products are  supplied  worldwide  to  the
computer,  medical,  industrial,  telecommunications,  data  communications  and
instrumentation markets.  PCC also  designs,  manufactures and  markets  battery
chargers  for the cellular  telephone market. A  significant proportion of PCC's
revenues in recent  periods has been  generated from a  single customer in  this
market.  PCC  has  custom  design  capabilities  and  has  recently  established
independent marketing organization in an  effort to increase its customer  base.
Representative  customers include Ericsson,  AT&T, Medtronic, Allen-Bradley, SCI
and Johnson Controls.

    The Company  has from  time-to-time received  indications of  interest  with
respect to both III and PCC, and has considered, and may in the future consider,
the sale of its interest in these subsidiaries.

                          DESCRIPTION OF CAPITAL STOCK

    Upon  the  closing of  this offering,  the authorized  capital stock  of the
Company will consist of 40,000,000 shares  of Common Stock, $.01 par value,  and
2,000,000 shares of Preferred Stock, $.01 par value.

COMMON STOCK

    As   of  July  1,  1995,  there  were  14,423,696  shares  of  Common  Stock
outstanding, and there were approximately 3,640 holders of record of the  Common
Stock.  The holders of Common Stock are entitled to one vote for each share held
of record  on  all matters  submitted  to a  vote  of stockholders.  Subject  to
preferences that may be applicable to any outstanding shares of Preferred Stock,
the  holders of Common Stock are entitled  to receive ratably such dividends, if
any, as may be declared from time to time by the Board of Directors out of funds
legally available for the  payment of dividends. See  "Dividend Policy." In  the
event of a liquidation, dissolution or winding up of the Company, the holders of
Common Stock are entitled to share ratably in all assets remaining after payment
of  liabilities  and  liquidation  preferences  of  any  outstanding  shares  of
Preferred Stock. Holders of Common Stock have no preemptive rights or rights  to
convert their Common Stock into any other securities. There are no redemption or
sinking  fund provisions applicable to the  Common Stock. All outstanding shares
of Common Stock  are fully  paid and non-assessable,  and the  shares of  Common
Stock  to be  issued upon  completion of  this offering  will be  fully paid and
non-assessable.

PREFERRED STOCK

    Pursuant to the Company's Restated  Certificate of Incorporation, the  Board
of  Directors has the authority, without  further action by the stockholders, to
issue up to 2,000,000 shares of Preferred Stock in one or more series and to fix
the designations, powers, preferences,  privileges, and relative  participating,
optional  or special rights and  the qualifications, limitations or restrictions
thereof, including dividend rights, conversion  rights, voting rights, terms  of
redemption  and liquidation preferences, any or all of which may be greater than
the rights of  the Common  Stock. The  Board of  Directors, without  stockholder
approval, will be able to issue Preferred Stock with voting, conversion or other
rights  that could  adversely affect  the voting power  and other  rights of the
holders of Common Stock. Preferred Stock could thus be issued quickly with terms
calculated to  delay or  prevent a  change in  control of  the Company  or  make
removal   of  management   more  difficult.   See  "Risk   Factors--  Effect  of
Anti-takeover Provisions."  Additionally, the  issuance of  Preferred Stock  may
have  the effect of decreasing the market price of the Common Stock. At present,
the Company has no plans to issue any of the Preferred Stock.

TRANSFER AGENT AND REGISTRAR

    The transfer agent and registrar for the Company's Common Stock is Bank One,

    In general, the rules of the Commission will prohibit the Underwriters  from
making  a market in the  Company's Common Stock during  the "cooling off" period
immediately preceding the commencement of sales in the offering. The  Commission
has,  however, adopted  exemptions from these  rules that  permit passive market
making under certain conditions. These  rules permit an underwriter to  continue
to  make a  market subject  to the  conditions, among  others, that  its bid not
exceed the highest bid  by a market  maker not connected  with the offering  and
that  its net  purchases on  any one trading  day not  exceed prescribed limits.
Pursuant to these exemptions, the  Underwriters, selling group members (if  any)
or  their respective affiliates intend to engage in passive market making in the
Company's Common Stock during the cooling off period.

                                 LEGAL MATTERS

    The validity of the Common Stock offered hereby will be passed upon for  the

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

    Section  145 of the  Delaware General Corporation Law  authorizes a court to
award or  a  corporation's  Board  of  Directors  to  grant  indemnification  to
directors   and   officers  in   terms   sufficiently  broad   to   permit  such
indemnification  under   certain   circumstances  for   liabilities   (including
reimbursement  for expenses incurred) arising under  the Securities Act of 1933,
as amended  (the  "Act"). Article  VII  Section  6 of  the  Registrant's  Bylaws
provides  for  mandatory  indemnification  of  its  directors  and  officers and
permissible indemnification of employees and other agents to the maximum  extent
permitted  by the Delaware General Corporation Law. The Registrant's Certificate
of Incorporation provides that,  pursuant to Delaware  law, its directors  shall
not  be liable for monetary damages for  breach of the directors' fiduciary duty
as a  director  to  the Company  and  its  stockholder. This  provision  in  the
Certificate  of Incorporation does not  eliminate the directors' fiduciary duty,
and in appropriate circumstances equitable remedies such as injunctive or  other
forms  of  non-monetary  relief will  remain  available under  Delaware  law. In
addition, each director will continue to  be subject to liability for breach  of
the  director's duty of loyalty to the Company for acts or omissions not in good
faith or involving intentional  misconduct, for knowing  violations of law,  for
actions leading to improper personal benefit to the director, and for payment of
dividends  or approval  of stock  repurchases or  redemptions that  are unlawful
under  Delaware  law.  The   provision  also  does   not  affect  a   director's
responsibilities  under any  other law, such  as the federal  securities laws or
state  or  federal   environmental  laws.  The   Registrant  has  entered   into
indemnification agreements with its officers and directors which are intended to
provide  the Registrant's officers and directors with further indemnification to
the maximum extent permitted by the Delaware General Corporation Law. In certain
instances, the  indemnification agreements  may result  in an  expansion of  the
substantive  protection available to  such individuals under  the Certificate of
Incorporation  and  Bylaws.  Reference  is  also  made  to  Section  7  of   the
Underwriting  Agreement contained  in Exhibit 1.1  hereto, indemnifying officers
and directors of the Registrant against certain liabilities.

ITEM 17.  UNDERTAKINGS.

    The   undersigned  Registrant  hereby  undertakes   that,  for  purposes  of
determining  any  liability  under  the  Securities  Act,  each  filing  of  the
Registrant's  annual report  pursuant to Section  13(a) or Section  15(d) of the
Exchange Act that  is incorporated  by reference in  the Registration  Statement
shall  be deemed to be  a new registration statement  relating to the securities
offered therein,  and the  offering of  such securities  at that  time shall  be
deemed to be the initial bona fide offering thereof.

    Insofar  as indemnification for liabilities arising under the Securities Act
may  be  permitted  to  directors,  officers  and  controlling  persons  of  the
Registrant  pursuant  to  the  provisions  of  the  Registrant's  Certificate of
Incorporation and Bylaws, Delaware Corporation Law, the Underwriting  Agreement,
or  otherwise,  the Registrant  has  been advised  that  in the  opinion  of the
Securities and Exchange Commission such indemnification is against public policy
as expressed in  the Securities  Act and  is, therefore,  unenforceable. In  the
event  that a claim for indemnification against such liabilities (other than the
payment by the Registrant of expenses incurred or paid by a director, officer or
controlling person of the  Registrant in the successful  defense of any  action,
suit  or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the Registrant will,  unless
in  the  opinion of  its  counsel the  matter  has been  settled  by controlling
precedent, submit to a  court of appropriate  jurisdiction the question  whether
such  indemnification  by  it  is  against public  policy  as  expressed  in the
Securities Act and will be governed by the final adjudication of such issue.

    The undersigned Registrant hereby undertakes that:

(1) For purposes  of determining  any liability  under the  Securities Act,  the
    information  omitted  from the  form  of prospectus  filed  as part  of this
    Registration Statement in reliance upon Rule 430A and contained in a form of
    prospectus filed by  the Registrant  pursuant to  Rule 424(b)(1)  or (4)  or
    497(h)  under  the  Securities  Act  shall be  deemed  to  be  part  of this
    Registration Statement as of the time it was declared effective.

(2) For the purpose of determining any liability under the Securities Act,  each
    post-effective  amendment that contains a form of prospectus shall be deemed
    to be  a  new registration  statement  relating to  the  securities  offered
    therein,  and the offering  therein, and the offering  of such securities at
    that time shall be deemed to be the initial bona fide offering thereof.

Ladies and Gentlemen:

    Burr-Brown  Corporation, a Delaware corporation (herein called the Company),
proposes to  issue and  sell 1,750,000  shares of  its authorized  but  unissued
Common  Stock, $.01 par  value (herein called the  Common Stock) (said 1,750,000
shares of Common Stock being herein called the Underwritten Stock). The  Company
proposes  to grant  to the  Underwriters (as  hereinafter defined)  an option to
purchase up to  262,500 additional  shares of  Common Stock  (herein called  the
Option  Stock and  with the  Underwritten Stock  herein collectively  called the
Stock). The Common Stock is more  fully described in the Registration  Statement
and the Prospectus hereinafter mentioned.

    The Company hereby confirms the agreements made with respect to the purchase
of  the Stock  by the several  underwriters, for  whom you are  acting, named in
Schedule I hereto (herein collectively called the Underwriters, which term shall
also include any underwriter purchasing Stock pursuant to Section 3(b) hereof).

    1.  REGISTRATION STATEMENT.  The  Company has filed with the Securities  and
Exchange  Commission (herein called the  Commission) a registration statement on
Form S-3 (No. 33-      ), including the related preliminary prospectus, for  the
registration  under the  Securities Act of  1933, as amended  (herein called the
Securities Act) of the Stock. Copies of such registration statement and of  each
amendment thereto, if any, including the related preliminary prospectus (meeting
the  requirements of Rule 430A  of the rules and  regulations of the Commission)
heretofore filed by the Company with the Commission have been delivered to you.

    The term Registration Statement  as used in this  agreement shall mean  such
registration  statement,  including  all  documents  incorporated  by  reference
therein,  all  exhibits  and  financial  statements,  all  information   omitted
therefrom in reliance upon Rule 430A and contained in the Prospectus referred to
below,  in the form in which it became effective, and any registration statement

    (a)The Company hereby represents and warrants as follows:

           (i)
           Each of the Company  and its subsidiaries  identified below has  been
           duly  incorporated and is  validly existing as  a corporation in good
    standing under the laws of the  jurisdiction of its incorporation, has  full

    business  as described in the Registration  Statement and the Prospectus and

    good  standing in all  jurisdictions in which the  character of the property
    owned or  leased  or the  nature  of the  business  transacted by  it  makes
    qualification  necessary (except where the failure  to be so qualified would
    not have a material  adverse effect on  the business, properties,  financial
    condition  or results  of operations  of the  Company and  its subsidiaries,
    taken  as   a  whole).   The  Company   has  the   following   subsidiaries:

                                        .  None  of  the  foregoing subsidiaries

    revenues  or is  otherwise material  to the  business, properties, financial
    condition or results of operations of the Company.

           Since the respective dates  as of which information  is given in  the
           Registration  Statement and  the Prospectus,  there has  not been any
    materially adverse change in  the business, properties, financial  condition
    or  results of operations  of the Company  and its subsidiaries,  taken as a
    whole, whether or not  arising from transactions in  the ordinary course  of
    business,  other than  as set  forth in  the Registration  Statement and the
    Prospectus, and since such dates, except in the ordinary course of business,
    neither the Company  nor either  of its  subsidiaries has  entered into  any
    material  transaction not referred to in  the Registration Statement and the
    Prospectus.

         (iii)
           The Registration  Statement and  the Prospectus  comply, and  on  the

    fact  and did  not omit  to state  any material  fact required  to be stated
    therein or necessary in order to make the statements therein not misleading;

    material  fact necessary  in order  to make  the statements  therein, in the
    light of  the circumstances  under  which they  were made,  not  misleading;
    provided,  however, that none of the  representations and warranties in this
    subparagraph (iii)  shall apply  to statements  in, or  omissions from,  the
    Registration  Statement  or  the Prospectus  made  in reliance  upon  and in
    conformity with information herein or otherwise furnished in writing to  the
    Company  by or  on behalf  of the Underwriters  for use  in the Registration
    Statement or the Prospectus.

           governmental   proceeding  to  which  the   Company  or  any  of  its
    subsidiaries is a party or  to which any property of  the Company or any  of
    its  subsidiaries is subject or, to the knowledge of the Company, threatened
    against the  Company  or  any  of  its  subsidiaries  which,  if  determined
    adversely  to the Company or any of  its subsidiaries, would have a material
    adverse effect on the condition (financial or other), results of operations,
    business, properties or prospects of the Company and its subsidiaries, taken
    as a whole, or which is required to be disclosed in the Prospectus.

           (x)
           The Company has not  and will not take,  directly or indirectly,  any

    manipulation  of the price of  the shares of Common  Stock to facilitate the
    sale of the Stock.

           Except as  described  in  the  Prospectus or  as  validly  waived  or

        (xiii)
           To  the  best of  the Company's  knowledge,  neither the  Company nor

    governmental  rule  or regulation  (including, without  limitation, federal,
    state and local rules and regulations relating to environmental, safety  and
    labor  matters) or court decree to which it may be subject, the violation of
    any of which would materially  adversely affect the condition (financial  or
    other),  business  prospects,  net worth  or  results of  operations  of the
    Company and its subsidiaries, taken as a whole.

         (xiv)
           The Company and its  subsidiaries have good  and marketable title  to

          (xv)
           The Company  has  filed with  the  Commission and  the  Nasdaq  Stock
           Market,  Inc. all documents required to be filed under the Securities
    Exchange Act of 1934, as amended  (the "Exchange Act"); when so filed,  each
    such  document complied with  the Exchange Act and  the applicable rules and
    regulations of the  Commission thereunder;  and each such  document did  not
    contain  any untrue statement of a material fact or omit to state a material
    fact necessary in order to make the statements therein, in the light of  the
    circumstances under which they were made, not misleading.

    3.  PURCHASE OF THE STOCK BY THE UNDERWRITERS.

    (a)On  the basis  of the representations  and warranties and  subject to the
       terms and conditions herein  set forth, the Company  agrees to issue  and
sell  1,750,000 shares of the Underwritten Stock to the several Underwriters and
each of the  Underwriters agrees  to purchase  from the  Company the  respective
aggregate  number of shares of Underwritten Stock set forth opposite its name in
Schedule I. The price at which such  shares of Underwritten Stock shall be  sold
by  the Company and  purchased by the  several Underwriters shall  be $      per
share. In making this Agreement,  each Underwriter is contracting severally  and
not jointly; except as provided in paragraphs (b) and (c) of this Section 3, the
agreement  of  each Underwriter  is to  purchase only  the respective  number of
shares of the Underwritten Stock specified in Schedule I.

    (b)If for  any  reason either  of  the  Underwriters shall  fail  or  refuse
       (otherwise  than for  a reason sufficient  to justify  the termination of
this Agreement under the provisions  of Section 8 or  9 hereof) to purchase  and
pay  for  the number  of shares  of the  Stock  agreed to  be purchased  by such
Underwriter or Underwriters, the Company  shall immediately give notice  thereof
to  you, and the non-defaulting Underwriter shall have the right within 24 hours
after the receipt  by you of  such notice to  purchase, or procure  one or  more
other  Underwriters  to purchase,  in  such proportions  as  may be  agreed upon
between you and such purchasing Underwriter  or Underwriters and upon the  terms
herein  set  forth, all  or  any part  of  the shares  of  the Stock  which such
defaulting Underwriter  agreed to  purchase. If  the non-defaulting  Underwriter
fails  so to make such arrangements with respect to all such shares and portion,
the number  of shares  of  the Stock  which  the non-defaulting  Underwriter  is
otherwise  obligated  to purchase  under this  Agreement shall  be automatically
increased to  absorb  the remaining  shares  and portion  which  the  defaulting
Underwriter  agreed  to  purchase; provided,  however,  that  the non-defaulting
Underwriter shall not be obligated to purchase the shares and portion which  the
defaulting Underwriter agreed to purchase if the aggregate number of such shares
of  the Stock exceeds 10% of  the total number of shares  of the Stock which the
other Underwriter agreed to purchase hereunder. If the total number of shares of
the Stock which the defaulting Underwriter

                                       4
<PAGE>
agreed to purchase shall not be purchased or absorbed in accordance with the two
preceding sentences, the  Company shall  have the  right, within  24 hours  next
succeeding the 24-hour period above referred to, to make arrangements with other
underwriters  or purchasers satisfactory to you  for purchase of such shares and
portion on the  terms herein  set forth.  In any such  case, either  you or  the
Company shall have the right to postpone the Closing Date determined as provided
in  Section  5 hereof  for  not more  than seven  business  days after  the date
originally fixed as the Closing  Date pursuant to said  Section 5 in order  that
any necessary changes in the Registration Statement, the Prospectus or any other
documents or arrangements may be made. If neither the non-defaulting Underwriter
nor  the Company shall make arrangements within the 24-hour periods stated above
for the purchase of all the shares of the Stock which the defaulting Underwriter
agreed to purchase hereunder, this Agreement shall be terminated without further
act or  deed and  without  any liability  on  the part  of  the Company  to  any
non-defaulting  Underwriter and  without any liability  on the part  of any non-
defaulting Underwriter to  the Company. Nothing  in this paragraph  (b), and  no
action  taken hereunder, shall relieve any defaulting Underwriter from liability
in respect of any default of such Underwriter under this Agreement.

    (c)On the  basis of  the representations,  warranties and  covenants  herein
       contained,  and subject to the terms and conditions herein set forth, the
Company grants an option to the several Underwriters to purchase, severally  and
not  jointly, up to 262,500 shares in the aggregate of the Option Stock from the
Company at  the same  price per  share as  the Underwriters  shall pay  for  the
Underwritten  Stock. Said option may be  exercised only to cover over-allotments
in the sale of the Underwritten Stock  by the Underwriters and may be  exercised
in  whole or  in part  at any  time (but not  more than  once) on  or before the
thirtieth day  after the  date of  this Agreement  upon written  or  telegraphic
notice by you to the Company setting forth the aggregate number of shares of the
Option  Stock as  to which the  several Underwriters are  exercising the option.
Delivery of certificates for the shares  of Option Stock, and payment  therefor,
shall  be made  as provided  in Section 5  hereof. The  number of  shares of the
Option Stock to be purchased by each Underwriter shall be the same percentage of
the total number of shares  of the Option Stock to  be purchased by the  several
Underwriters  as such  Underwriter is purchasing  of the  Underwritten Stock, as
adjusted by you in such manner as you deem advisable to avoid fractional shares.

    4.  OFFERING BY UNDERWRITERS.

    (a)The terms of the public offering by  the Underwriters of the Stock to  be
       purchased  by  them  shall  be  as  set  forth  in  the  Prospectus.  The
Underwriters may from time  to time change the  public offering price after  the
closing  of the  public offering  and increase  or decrease  the concessions and
discounts to dealers as they may determine.

    (b)The information set forth in the  last paragraph on the front cover  page

business days preceding the Closing Date), and payment therefor (the "Closing"),

    (b)If the option  granted by Section  3(c) hereof shall  be exercised  after

the Closing Date, delivery of certificates  for the shares of Option Stock,  and
payment  therefor, shall be made  at the office of  Brobeck, Phleger & Harrison,

on the third business day after the exercise of such option.

    (c)Payment for the Stock shall be made to the Company or its order by one or

of  the  Option  Stock.  Such  certificates  will  be  made  available  to   the
Underwriters  for inspection,  checking and  packaging at  the offices  of Lewco

other  Underwriter, may  (but shall  not be  obligated to)  make payment  to the
Company for shares to  be purchased by the  other Underwriter whose check  shall
not  have been received  by you on the  Closing Date or any  later date on which
Option Stock is purchased for the account of such Underwriter. Any such  payment
by  either  of you  shall  not relieve  the other  Underwriter  from any  of its
obligations hereunder.

    6.  FURTHER AGREEMENTS OF THE  COMPANY. The Company covenants and agrees  as
follows:

    (a)The  Company will (i)  prepare and timely file  with the Commission under
       Rule 424(b) a Prospectus containing information previously omitted at the
time of effectiveness of the Registration Statement in reliance on Rule 430A and
(ii) not file any amendment to  the Registration Statement or supplement to  the
Prospectus  of which  you shall not  previously have been  advised and furnished
with a copy or to which you  shall have reasonably objected in writing or  which
is not in compliance with the Securities Act or the rules and regulations of the
Commission.

    (b)The Company will promptly notify each Underwriter in the event of (i) the
       request  by the Commission for amendment of the Registration Statement or
for supplement to  the Prospectus or  for any additional  information, (ii)  the
issuance by the Commission of any stop order suspending the effectiveness of the
Registration  Statement, (iii) the institution or notice of intended institution
of any action or proceeding for that purpose, (iv) the receipt by the Company of
any notification with  respect to  the suspension  of the  qualification of  the
Stock  for sale in any jurisdiction,  or (v) the receipt by  it of notice of the
initiation or threatening of any proceeding  for such purpose. The Company  will
make  every reasonable effort to prevent the  issuance of such a stop order and,
if such an order shall at any  time be issued, to obtain the withdrawal  thereof
at the earliest possible moment.

    (c)The  Company will  (i) on or  before the  Closing Date, deliver  to you a
       signed copy of the Registration Statement as originally filed and of each
amendment thereto filed  prior to  the time the  Registration Statement  becomes
effective  and,  promptly  upon  the  filing  thereof,  a  signed  copy  of each
post-effective amendment, if any, to the Registration Statement (together  with,
in  each case, all exhibits thereto unless previously furnished to you) and will
also deliver to you, for distribution  to the Underwriters, a sufficient  number
of  additional conformed copies of each  of the foregoing (but without exhibits)
so that  one copy  of  each may  be distributed  to  each Underwriter,  (ii)  as
promptly  as possible deliver  to you and  send to the  several Underwriters, at
such office or offices as you may

                                       6
<PAGE>
designate, as many copies of the  Prospectus as you may reasonably request,  and
(iii)  thereafter from time to  time during the period  in which a prospectus is
required by law to be  delivered by an Underwriter  or dealer, likewise send  to
the  Underwriters as many additional copies of the Prospectus and as many copies
of any supplement to the Prospectus and of any amended prospectus, filed by  the
Company  with the  Commission, as  you may  reasonably request  for the purposes
contemplated by the Securities Act.

    (d)If at any time during the period in which a prospectus is required by law
       to be delivered  by an  Underwriter or dealer  any event  relating to  or
affecting  the Company, or of  which the Company shall  be advised in writing by
you, shall occur as a result of which it is necessary, in the opinion of counsel
for the Company or of counsel for  the Underwriters, to supplement or amend  the
Prospectus  in order to make  the Prospectus not misleading  in the light of the
circumstances existing at the time it is delivered to a purchaser of the  Stock,
the  Company will forthwith prepare and file with the Commission a supplement to
the  Prospectus  or  an  amended  prospectus  so  that  the  Prospectus  as   so
supplemented or amended will not contain any untrue statement of a material fact
or  omit to state  any material fact  necessary in order  to make the statements
therein, in the light of the circumstances existing at the time such  Prospectus
is delivered to such purchaser, not misleading. If, after the public offering of
the  Stock by  the Underwriters and  during such period,  the Underwriters shall
propose to vary the terms  of offering thereof by  reason of changes in  general
market  conditions or otherwise, you  will advise the Company  in writing of the
proposed variation, and, if in the opinion either of counsel for the Company  or
of  counsel  for  the Underwriters  such  proposed variation  requires  that the
Prospectus be supplemented or  amended, the Company  will forthwith prepare  and
file with the Commission a supplement to the Prospectus or an amended prospectus
setting  forth such variation.  The Company authorizes  the Underwriters and all
dealers to whom any of the Stock may be sold by the several Underwriters to  use
the Prospectus, as from time to time amended or supplemented, in connection with
the  sale  of the  Stock in  accordance  with the  applicable provisions  of the
Securities Act  and the  applicable rules  and regulations  thereunder for  such
period.

    (e)Prior  to the filing thereof with the Commission, the Company will submit
       to you, for your information, a  copy of any post-effective amendment  to
the  Registration Statement and any supplement  to the Prospectus or any amended
prospectus proposed to be filed.

    (f)The Company  will  cooperate,  when  and as  requested  by  you,  in  the
       qualification  of the  Stock for offer  and sale under  the securities or
blue sky laws of such jurisdictions as you may designate and, during the  period
in  which a prospectus is  required by law to be  delivered by an Underwriter or
dealer, in keeping such qualifications in good standing under said securities or
blue sky laws;  provided, however, that  the Company shall  not be obligated  to
file  any  general consent  to service  of process  or to  qualify as  a foreign
corporation in any  jurisdiction in which  it is not  so qualified. The  Company
will,  from time to time,  prepare and file such  statements, reports, and other
documents as are or  may be required to  continue such qualifications in  effect
for  so long  a period  as you  may reasonably  request for  distribution of the
Stock.

    (g)During a  period of  five  years commencing  with  the date  hereof,  the
       Company  will furnish to you, and to  each Underwriter who may so request
in writing, copies of all periodic and special reports furnished to stockholders
of the Company  and of  all information, documents  and reports  filed with  the
Commission.

    (h)Not later than the 45th day following the end of the fiscal quarter first
       occurring  after the first anniversary of the Effective Date, the Company
will make generally available to its  security holders an earnings statement  in
accordance with Section 11(a) of the Securities Act and Rule 158 thereunder.

    (i)The  Company  agrees  to  pay  all costs  and  expenses  incident  to the
       performance of its obligations under this Agreement, including all  costs
and  expenses  incident to  (i) the  preparation, printing  and filing  with the
Commission and the National Association of Securities Dealers, Inc. ("NASD")  of
the  Registration Statement, any Preliminary Prospectus and the Prospectus, (ii)
the furnishing to the

                                       7
<PAGE>
Underwriters of  copies  of  any  Preliminary  Prospectus  and  of  the  several
documents  required by paragraph (c) of this Section 6 to be so furnished, (iii)
the  printing  of  this  Agreement  and  related  documents  delivered  to   the
Underwriters,  (iv) the preparation, printing and  filing of all supplements and
amendments to the Prospectus referred to in paragraph (d) of this Section 6, (v)
the furnishing  to you  and  the Underwriters  of  the reports  and  information
referred  to  in paragraph  (g)  of this  Section 6  and  (vi) the  printing and
issuance of stock certificates, including the transfer agent's fees.

    (j)The Company  agrees to  reimburse you,  for the  account of  the  several
       Underwriters,  for  blue sky  fees  and related  disbursements (including
counsel  fees  and  disbursements  and  cost  of  printing  memoranda  for   the
Underwriters) paid by or for the account of the Underwriters or their counsel in
qualifying  the Stock under state securities or  blue sky laws and in the review
of the offering by the NASD.

    (k)The Company  hereby agrees  that, without  the prior  written consent  of
       Hambrecht  & Quist  LLC on behalf  of the Underwriters,  the Company will
not, for a period of 90 days  following the commencement of the public  offering
of  the  Stock by  the Underwriters,  directly or  indirectly, (i)  sell, offer,
contract to sell, make any  short sale, pledge, sell  any option or contract  to
purchase,  purchase any option or  contract to sell, grant  any option, right or
warrant to purchase  or otherwise transfer  or dispose of  any shares of  Common
Stock  or any securities convertible into  or exchangeable or exercisable for or
any rights to purchase or  acquire Common Stock or (ii)  enter into any swap  or
other  agreement  that transfers,  in  whole or  in  part, any  of  the economic
consequences  or  ownership  of  Common  Stock,  whether  any  such  transaction
described  in clause (i)  or (ii) above is  to be settled  by delivery of Common
Stock or such  other securities, in  cash or otherwise.  The foregoing  sentence
shall not apply to (A) the Stock to be sold to the Underwriters pursuant to this
Agreement, (B) shares of Common Stock issued by the Company upon the exercise of
options  granted  under  the stock  option  plans  of the  Company  (the "Option
Plans"), all  as  described  in  footnote  1 to  the  table  under  the  caption
"Capitalization"  in  the Preliminary  Prospectus, and  (C) options  to purchase
Common Stock granted under the Option Plans.

    (l)The Company  agrees to  use  its best  efforts  to cause  all  directors,
       officers,  and  beneficial holders  of more  than  5% of  the outstanding
Common Stock to  agree that, without  the prior written  consent of Hambrecht  &
Quist  LLC on behalf of the Underwriters, such  person or entity will not, for a
period of 90 days following the commencement of the public offering of the Stock
by the Underwriters, directly or indirectly, (i) sell, offer, contract to  sell,
make  any short sale, pledge, sell any  option or contract to purchase, purchase
any option or contract to sell, grant  any option, right or warrant to  purchase
or otherwise transfer or dispose of any shares of Common Stock or any securities
convertible into or exchangeable or exercisable for or any rights to purchase or
acquire  Common  Stock or  (ii)  enter into  any  swap or  other  agreement that
transfers, in whole or in part, any of the economic consequences or ownership of
Common Stock, whether any such transaction described in clause (i) or (ii) above
is to be settled by delivery of  Common Stock or such other securities, in  cash
or otherwise.

    (m)The  Company  is familiar  with the  Investment Company  Act of  1940, as
       amended, and  has in  the past  conducted its  affairs, and  will in  the
future  conduct its affairs, in such a manner to ensure that the Company was not
and will  not  be  an "investment  company"  or  a company  "controlled"  by  an
"investment  company" within the meaning of  the Investment Company Act of 1940,
as amended, and the rules and regulations thereunder.

    7.  INDEMNIFICATION AND CONTRIBUTION.

    (a)The Company agrees to  indemnify and hold  harmless each Underwriter  and
       each  person (including each partner or officer thereof) who controls any
Underwriter within the  meaning of  Section 15 of  the Securities  Act from  and
against any and all losses, claims, damages or liabilities, joint or several, to
which  such indemnified  parties or  any of  them may  become subject  under the
Securities Act, the Securities Exchange Act  of 1934, as amended (herein  called
the  Exchange Act), or  the common law  or otherwise, and  the Company agrees to
reimburse each such Underwriter  and controlling person for  any legal or  other
expenses (including, except as otherwise hereinafter provided,

                                       8
<PAGE>
reasonable  fees  and  disbursements  of  counsel)  incurred  by  the respective
indemnified parties  in  connection  with defending  against  any  such  losses,
claims,  damages  or  liabilities or  in  connection with  any  investigation or
inquiry of, or  other proceeding which  may be brought  against, the  respective
indemnified  parties, in each case  arising out of or  based upon (i) any untrue
statement or  alleged untrue  statement  of a  material  fact contained  in  the
Registration  Statement (including the  Prospectus as part  thereof and any Rule
462(b)  registration  statement)   or  any   post-effective  amendment   thereto
(including  any Rule 462(b) registration statement),  or the omission or alleged
omission to  state therein  a material  fact required  to be  stated therein  or
necessary  to make  the statements  therein not  misleading, or  (ii) any untrue
statement or  alleged untrue  statement  of a  material  fact contained  in  any
Preliminary  Prospectus or the Prospectus (as  amended or as supplemented if the
Company shall have filed with the Commission any amendment thereof or supplement
thereto) or the omission  or alleged omission to  state therein a material  fact
necessary  in  order  to  make  the statements  therein,  in  the  light  of the
circumstances under which  they were  made, not  misleading; provided,  however,
that (1) the indemnity agreements of the Company contained in this paragraph (a)
shall  not apply to any such losses, claims, damages, liabilities or expenses if
such statement or  omission was  made in reliance  upon and  in conformity  with
information  furnished as herein stated or otherwise furnished in writing to the
Company by or on behalf of any Underwriter for use in any Preliminary Prospectus
or the Registration Statement or the Prospectus or any such amendment thereof or
supplement thereto and (2) the  indemnity agreement contained in this  paragraph
(a) with respect to any Preliminary Prospectus shall not inure to the benefit of
any Underwriter from whom the person asserting any such losses, claims, damages,
liabilities  or expenses purchased the Stock which is the subject thereof (or to
the benefit of any person  controlling such Underwriter) if  at or prior to  the
written  confirmation of the sale of such Stock a copy of the Prospectus (or the
Prospectus as amended or supplemented) was not sent or delivered to such  person
(excluding  the  documents incorporated  therein  by reference)  and  the untrue
statement  or  omission  of  a  material  fact  contained  in  such  Preliminary
Prospectus  was corrected  in the  Prospectus (or  the Prospectus  as amended or
supplemented) unless the failure is the  result of noncompliance by the  Company
with  paragraph (c) of Section 6 hereof. The indemnity agreements of the Company
contained in this paragraph  (a) and the representations  and warranties of  the
Company  contained in Section 2 hereof shall  remain operative and in full force
and effect  regardless  of  any  investigation  made by  or  on  behalf  of  any
indemnified party and shall survive the delivery of and payment for the Stock.

    (b)Each  Underwriter  severally agrees  to indemnify  and hold  harmless the
       Company, each of its officers who signs the Registration Statement on his
own behalf or pursuant to a power of attorney, each of its directors, each other
Underwriter and  each person  (including each  partner or  officer thereof)  who
controls the Company or any such other Underwriter within the meaning of Section
15  of the Securities Act, from and  against any and all losses, claims, damages
or liabilities, joint or  several, to which such  indemnified parties or any  of
them  may become  subject under  the Securities  Act, the  Exchange Act,  or the
common law or otherwise  and to reimburse  each of them for  any legal or  other
expenses  (including, except as otherwise  hereinafter provided, reasonable fees
and disbursements of counsel) incurred by the respective indemnified parties  in
connection   with  defending  against  any   such  losses,  claims,  damages  or
liabilities or in  connection with  any investigation  or inquiry  of, or  other
proceeding  which may be brought against, the respective indemnified parties, in
each case arising  out of  or based  upon (i)  any untrue  statement or  alleged
untrue  statement of  a material  fact contained  in the  Registration Statement
(including the  Prospectus as  part  thereof and  any Rule  462(b)  registration
statement)  or any post-effective  amendment thereto (including  any Rule 462(b)
registration statement) or the omission or  alleged omission to state therein  a
material  fact required to be stated therein or necessary to make the statements
therein not misleading or (ii) any untrue statement or alleged untrue  statement
of a material fact contained in the Prospectus (as amended or as supplemented if
the  Company  shall have  filed  with the  Commission  any amendment  thereof or
supplement thereto)  or the  omission or  alleged omission  to state  therein  a
material fact necessary in order to make the statements therein, in the light of
the  circumstances under which they were made, not misleading, if such statement
or omission  was  made in  reliance  upon  and in  conformity  with  information
furnished as

                                       9
<PAGE>
herein  stated or otherwise furnished in writing  to the Company by or on behalf
of such indemnifying Underwriter  for use in the  Registration Statement or  the
Prospectus  or any such  amendment thereof or  supplement thereto. The indemnity
agreement of  each Underwriter  contained  in this  paragraph (b)  shall  remain
operative  and in full force and effect  regardless of any investigation made by
or on behalf  of any indemnified  party and  shall survive the  delivery of  and
payment for the Stock.

    (c)Each  party indemnified under the provision  of paragraphs (a) and (b) of
       this Section  7 agrees  that, upon  the  service of  a summons  or  other
initial  legal process upon  it in any  action or suit  instituted against it or
upon  its  receipt  of   written  notification  of   the  commencement  of   any
investigation  or  inquiry of,  or proceeding  against, it  in respect  of which
indemnity may be sought on account of any indemnity agreement contained in  such
paragraphs,  it will promptly give written  notice (herein called the Notice) of
such service or notification to the  party or parties from whom  indemnification
may  be sought  hereunder. No  indemnification provided  for in  such paragraphs
shall be available  to any party  who shall fail  so to give  the Notice if  the
party  to  whom such  Notice  was not  given was  unaware  of the  action, suit,
investigation, inquiry or proceeding to which the Notice would have related  and
was  prejudiced by the failure to give the Notice, but the omission so to notify
such indemnifying party or parties of any such service or notification shall not
relieve such indemnifying party or parties  from any liability which it or  they
may  have to the indemnified party for contribution or otherwise than on account
of such indemnity agreement. Any indemnifying party shall be entitled at its own
expense to participate in the defense of any action, suit or proceeding against,
or investigation or  inquiry of,  an indemnified party.  Any indemnifying  party
shall be entitled, if it so elects within a reasonable time after receipt of the
Notice  by giving written  notice (herein called  the Notice of  Defense) to the
indemnified  party,  to  assume  (alone   or  in  conjunction  with  any   other
indemnifying  party  or  parties)  the  entire  defense  of  such  action, suit,
investigation, inquiry  or proceeding,  in  which event  such defense  shall  be
conducted,  at  the expense  of the  indemnifying party  or parties,  by counsel
chosen by such indemnifying party or parties and reasonably satisfactory to  the
indemnified  party or  parties; provided, however,  that (i)  if the indemnified
party or parties reasonably determine that  there may be a conflict between  the
positions  of the indemnifying party or parties  and of the indemnified party or
parties in conducting the defense  of such action, suit, investigation,  inquiry
or  proceeding or that there may be legal defenses available to such indemnified
party or  parties  different from  or  in addition  to  those available  to  the
indemnifying party or parties, then counsel for the indemnified party or parties
shall  be entitled to conduct the defense to the extent reasonably determined by
such counsel to be necessary to  protect the interests of the indemnified  party
or  parties and  (ii) in any  event, the  indemnified party or  parties shall be
entitled to have counsel chosen by such indemnified party or parties participate
in, but not conduct, the defense. If, within a reasonable time after receipt  of
the  Notice, an  indemnifying party  gives a Notice  of Defense  and the counsel
chosen by the indemnifying  party or parties is  reasonably satisfactory to  the
indemnified  party or  parties, the  indemnifying party  or parties  will not be
liable under paragraphs (a) through (c) of this Section 7 for any legal or other
expenses subsequently incurred by the indemnified party or parties in connection
with the  defense of  the action,  suit, investigation,  inquiry or  proceeding,
except that (A) the indemnifying party or parties shall bear the legal and other
expenses  incurred in connection with the conduct  of the defense as referred to
in clause (i) of the proviso to the preceding sentence and (B) the  indemnifying
party or parties shall bear such other expenses as it or they have authorized to
be  incurred by the indemnified  party or parties. If,  within a reasonable time
after receipt  of  the  Notice,  no  Notice  of  Defense  has  been  given,  the
indemnifying  party  or parties  shall  be responsible  for  any legal  or other
expenses incurred by  the indemnified party  or parties in  connection with  the
defense of the action, suit, investigation, inquiry or proceeding.

    (d)If  the indemnification provided for in  this Section 7 is unavailable or
       insufficient to hold harmless an indemnified party under paragraph (a) or
(b) of this  Section 7, then  each indemnifying party,  in lieu of  indemnifying
such  indemnified party, shall contribute to the  amount paid or payable by such
indemnified party as  a result  of the  losses, claims,  damages or  liabilities
referred  to in paragraph (a) or (b) of this Section 7 (i) in such proportion as
is appropriate to reflect  the relative benefits  received by each  indemnifying
party   from   the  offering   of   the  Stock   or   (ii)  if   the  allocation

                                       10
<PAGE>
provided by  clause  (i) above  is  not permitted  by  applicable law,  in  such
proportion  as is appropriate to reflect not only the relative benefits referred
to in clause (i) above but also the relative fault of each indemnifying party in
connection with  the  statements or  omissions  that resulted  in  such  losses,
claims,  damages or liabilities, or  actions in respect thereof,  as well as any
other relevant equitable considerations. The  relative benefits received by  the
Company  and  the Underwriters  shall be  deemed  to be  in the  same respective
proportions as the total net proceeds from the offering of the Stock received by
the Company and the total underwriting discount received by the Underwriters, as
set forth  in the  table  on the  cover  page of  the  Prospectus, bear  to  the
aggregate public offering price of the Stock. Relative fault shall be determined
by  reference  to, among  other  things, whether  the  untrue or  alleged untrue
statement of a  material fact or  the omission  or alleged omission  to state  a
material fact relates to information supplied by each indemnifying party and the
parties'  relative intent, knowledge,  access to information  and opportunity to
correct or prevent such untrue statement or omission.

    The parties agree that  it would not be  just and equitable if  contribution
pursuant  to this  paragraph (d)  were to be  determined by  pro rata allocation
(even if the Underwriters were treated as one entity for such purpose) or by any
other method  of allocation  which  does not  take  into account  the  equitable
considerations  referred to  in the  first sentence  of this  paragraph (d). The
amount paid by an indemnified party as  a result of the losses, claims,  damages
or liabilities, or actions in respect thereof, referred to in the first sentence
of  this paragraph (d)  shall be deemed  to include any  legal or other expenses
reasonably incurred by such indemnified party in connection with  investigation,
preparing  to  defend or  defending against  any  action or  claim which  is the
subject of this paragraph (d). Notwithstanding the provisions of this  paragraph
(d),  no Underwriter shall be required to contribute any amount in excess of the
underwriting discount applicable to the Stock purchased by such Underwriter.  No
person  guilty of  fraudulent misrepresentation  (within the  meaning of Section
11(f) of the Securities Act) shall  be entitled to contribution from any  person
who  was  not guilty  of  such fraudulent  misrepresentation.  The Underwriters'
obligations in this  paragraph (d) to  contribute are several  in proportion  to
their respective underwriting obligations and not joint.

    Each  party  entitled to  contribution  agrees that  upon  the service  of a
summons or other initial legal process upon it in any action instituted  against
it in respect of which contribution may be sought, it will promptly give written
notice  of such service  to the party  or parties from  whom contribution may be
sought, but the omission so to notify such party or parties of any such  service
shall  not  relieve the  party from  whom  contribution may  be sought  from any
obligation it may have hereunder  or otherwise (except as specifically  provided
in paragraph (c) of this Section 7).

    (e)No  indemnifying party  will, without the  prior written  consent of each
       indemnified party, settle or  compromise or consent to  the entry of  any
judgment  in  any pending  or threatened  claim, action,  suit or  proceeding in
respect of which indemnification  may be sought hereunder  (whether or not  such
indemnified  party or any person who  controls such indemnified party within the
meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act is
a party  to such  claim, action,  suit or  proceeding) unless  such  settlement,
compromise  or  consent includes  an unconditional  release of  such indemnified
party and each such  controlling person from all  liability arising out of  such
claim, action, suit or proceeding.

    8.   TERMINATION.  This Agreement may be terminated by you at any time prior
to the Closing Date by giving written notice to the Company if after the date of
this Agreement trading  in the  Common Stock shall  have been  suspended, or  if
there  shall have occurred (i) the engagement in hostilities or an escalation of
major hostilities by the United States or  the declaration of war or a  national
emergency by the United States on or after the date hereof, (ii) any outbreak of
hostilities  or other national or international  calamity or crisis or change in
economic or  political conditions  if  the effect  of such  outbreak,  calamity,
crisis or change in economic or political conditions in the financial markets of
the  United States  would, in  the Underwriters'  reasonable judgment,  make the
offering or delivery of the Stock impracticable, (iii) suspension of trading  in
securities  generally  or  a material  adverse  decline in  value  of securities
generally on  the New  York Stock  Exchange, the  American Stock  Exchange,  The
Nasdaq  Stock Market, or limitations on  prices (other than limitations on hours
or

                                       11
<PAGE>
numbers of days of  trading) for securities on  either such exchange or  system,
(iv)  the enactment, publication, decree or other promulgation of any federal or
state statute, regulation, rule or order  of, or commencement of any  proceeding
or  investigation by, any court, legislative  body, agency or other governmental
authority which in the Underwriters' reasonable opinion materially and adversely
affects or will materially or adversely affect the business or operations of the
Company, (v) declaration of a banking  moratorium by either federal or New  York
State  authorities or  (vi) the taking  of any  action by any  federal, state or
local government or agency in respect of its monetary or fiscal affairs which in
the Underwriters'  reasonable  opinion has  a  material adverse  effect  on  the
securities  markets in the United States.  If this Agreement shall be terminated
pursuant to this Section 8,  there shall be no liability  of the Company to  the
Underwriters  and no  liability of  the Underwriters  to the  Company; provided,
however, that  in  the event  of  any such  termination  the Company  agrees  to
indemnify and hold harmless the Underwriters from all costs or expenses incident
to  the  performance of  the obligations  of the  Company under  this Agreement,
including all  costs and  expenses referred  to  in paragraphs  (i) and  (j)  of
Section 6 hereof.

    9.  CONDITIONS OF UNDERWRITERS' OBLIGATIONS.  The obligations of the several
Underwriters  to  purchase  and  pay  for the  Stock  shall  be  subject  to the
performance by the Company of all  its obligations to be performed hereunder  at

    Option  Stock is  purchased at any  date after the  Closing Date, additional

    necessary  in  order  to  make  the  statements  therein,  respectively, not
    misleading, (ii)  since the  Effective  Date, no  event has  occurred  which
    should  have been set forth  in a supplement or  amendment to the Prospectus
    which has not been set forth in such a supplement or amendment, (iii)  since

    or  any development  involving a prospective  material adverse  change in or
    affecting the  business,  properties,  financial  condition  or  results  of
    operations of the Company and its subsidiaries, taken as a whole, whether or
    not arising from transactions in the ordinary course of business, and, since
    such  dates, except in the ordinary  course of business, neither the Company

    render  it  impracticable  in  your reasonable  judgment  to  make  a public
    offering of the  Stock, or a  material adverse change  in market levels  for
    securities  in general (or those of companies in particular) or financial or
    economic conditions which render it inadvisable to proceed.

       (e) You shall have received on the Closing Date and on any later date  on

    letter  delivered to you  concurrently with the  execution of this Agreement
    (herein called the Original Letter), but carried out to a date not more than
    three business days prior to  the Closing Date or  such later date on  which
    Option  Stock  is purchased  (i) confirming,  to the  extent true,  that the
    statements and conclusions set forth in the Original Letter are accurate  as
    of the Closing Date or such later date, as the case may be, and (ii) setting
    forth  any revisions  and additions  to the  statements and  conclusions set
    forth in the Original Letter which  are necessary to reflect any changes  in
    the  facts described in the  Original Letter since the  date of the Original
    Letter or to reflect the  availability of more recent financial  statements,
    data  or  information. The  letters shall  not disclose  any change,  or any
    development involving a prospective change, in or affecting the business  or
    properties  of the Company  or any of  its subsidiaries which,  in your sole
    judgment, makes it  impractical or  inadvisable to proceed  with the  public
    offering of the Stock or the purchase of the Option Stock as contemplated by
    the Prospectus.

       (g) You   shall  have  been  furnished   evidence  in  usual  written  or
           telegraphic form  from the  appropriate  authorities of  the  several
    jurisdictions,  or other evidence satisfactory  to you, of the qualification
    referred to in paragraph (f) of Section 6 hereof.

       (h) Prior to the Closing Date, the Stock shall have been duly  authorized
           for  listing by  the Nasdaq National  Market upon  official notice of
    issuance.

       (i) On or prior  to the Closing  Date, you shall  have received from  all
           directors,  officers and  beneficial holders of  more than  5% of the
    outstanding Common  Stock agreements,  in  form reasonably  satisfactory  to
    Hambrecht  & Quist  LLC stating  that without  the prior  written consent of
    Hambrecht & Quist LLC on behalf  of the Underwriters, such person or  entity
    will  not, for a period of 90  days following the commencement of the public
    offering of the Stock by the Underwriters, directly or indirectly, (i) sell,
    offer, contract to  sell, make any  short sale, pledge,  sell any option  or
    contract  to purchase,  purchase any option  or contract to  sell, grant any
    option, right or warrant to purchase or otherwise transfer or dispose of any
    shares of Common Stock or any securities convertible into or exchangeable or
    exercisable for or any  rights to purchase or  acquire Common Stock or  (ii)
    enter  into any swap or other agreement that transfers, in whole or in part,

                                       13
<PAGE>
    any of the economic consequences or  ownership of Common Stock, whether  any
    such  transaction described in clause (i) or  (ii) above is to be settled by
    delivery of Common Stock or such other securities, in cash or otherwise.

       (j) On or prior  to the Closing  Date, you shall  have received from  the
           Company's transfer agent a certificate, dated as of a recent date, as
    to the outstanding shares of the Company's Common Stock.

    All  the agreements, opinions,  certificates and letters  mentioned above or
elsewhere in  this  Agreement shall  be  deemed to  be  in compliance  with  the
provisions  hereof only  if Morrison &  Foerster, counsel  for the Underwriters,
shall be satisfied that they comply in form and scope.

    In case any  of the  conditions specified  in this  Section 9  shall not  be
fulfilled,  this Agreement  may be  terminated by  you by  giving notice  to the
Company. Any such termination shall be  without liability of the Company to  the
Underwriters and without liability of the Underwriters to the Company; provided,
however,  that  (i) in  the event  of  such termination,  the Company  agrees to
indemnify and hold harmless the Underwriters from all costs or expenses incident
to the  performance of  the obligations  of the  Company under  this  Agreement,
including  all  costs and  expenses referred  to  in paragraphs  (i) and  (j) of
Section 6 hereof, and (ii) if this Agreement is terminated by you because of any
refusal, inability  or  failure  on the  part  of  the Company  to  perform  any
agreement herein, to fulfill any of the conditions herein, or to comply with any
provision  hereof other than by reason of  a default by any of the Underwriters,
the Company  will  reimburse the  Underwriters  severally upon  demand  for  all
out-of-pocket  expenses (including reasonable fees and disbursements of counsel)
that shall  have been  incurred  by them  in  connection with  the  transactions
contemplated hereby.

    10.   CONDITIONS OF  THE OBLIGATION OF  THE COMPANY.   The obligation of the
Company to deliver the  Stock shall be  subject to the  conditions that (a)  the
Registration  Statement  shall  have  become effective  and  (b)  no  stop order
suspending the  effectiveness thereof  shall  be in  effect and  no  proceedings
therefor shall be pending or threatened by the Commission.

    In  case either of the conditions specified  in this Section 10 shall not be
fulfilled, this Agreement may be terminated  by the Company by giving notice  to
you.  Any such  termination shall  be without  liability of  the Company  to the
Underwriters and without liability of the Underwriters to the Company; provided,
however, that  in  the event  of  any such  termination  the Company  agrees  to
indemnify and hold harmless the Underwriters from all costs or expenses incident
to  the  performance of  the obligations  of the  Company under  this Agreement,
including all  costs and  expenses referred  to  in paragraphs  (i) and  (j)  of
Section 6 hereof.

    11.    REIMBURSEMENT  OF  CERTAIN  EXPENSES.    In  addition  to  its  other
obligations under Section  7 of  this Agreement,  the Company  hereby agrees  to
reimburse  on a  quarterly basis the  Underwriters for all  reasonable legal and
other expenses incurred in connection with investigating or defending any claim,
action, investigation, inquiry or other proceeding arising out of or based  upon
any  statement or omission,  or any alleged statement  or omission, described in
paragraph (a) of Section 7 of  this Agreement, notwithstanding the absence of  a
judicial determination as to the propriety and enforceability of the obligations
under this Section 11 and the possibility that such payments might later be held
to  be improper; provided, however,  that (i) to the  extent any such payment is
ultimately held  to  be improper,  the  persons receiving  such  payments  shall
promptly  refund them and (ii)  such persons shall provide  to the Company, upon
request, reasonable assurances of their ability  to effect any refund, when  and
if due.

    12.   PERSONS ENTITLED TO BENEFIT OF  AGREEMENT.  This Agreement shall inure
to the benefit of the Company and the several Underwriters and, with respect  to
the  provisions of  Section 7  hereof, the several  parties (in  addition to the
Company and the several Underwriters)  indemnified under the provisions of  said
Section  7,  and  their  respective  personal  representatives,  successors  and
assigns. Nothing in this Agreement is intended or shall be construed to give  to
any other person, firm or

                                       14
<PAGE>
corporation  any legal or equitable remedy or  claim under or in respect of this
Agreement or any provision herein  contained. The term "successors and  assigns"
as herein used shall not include any purchaser, as such purchaser, of any of the
Stock from any of the several Underwriters.

agreements  contained in this Agreement  and the representations, warranties and
covenants in this Agreement shall remain in full force and effect regardless  of
(a)  any termination  of this  Agreement, (b)  any investigation  made by  or on
behalf of any Underwriter or controlling person  thereof, or by or on behalf  of
the  Company or  their respective  directors or  officers, and  (c) delivery and
payment for the  Stock under  this Agreement;  provided, however,  that if  this
Agreement  is terminated prior to the Closing Date, the provisions of paragraphs
(k) and (l) of Section 6 hereof shall be of no further force or effect.

    This Agreement may be  executed in two or  more counterparts, each of  which
shall  be deemed an original, but all of which together shall constitute one and

                                    ANNEX A
                    MATTERS TO BE COVERED IN THE OPINION OF
                          BROBECK, PHLEGER & HARRISON,
                            COUNSEL FOR THE COMPANY

         (i)
       Each  of the Company and its  subsidiaries has been duly incorporated and
       is validly existing as a corporation  in good standing under the laws  of
the   jurisdiction  of  its  incorporation,  is  duly  qualified  as  a  foreign
corporation and in good standing in each  state of the United States of  America
in  which  its  ownership or  leasing  of property  requires  such qualification
(except where the failure to be so  qualified would not have a material  adverse
effect on the business, properties, financial condition or results of operations
of  the Company and its subsidiaries, taken  as a whole), and has full corporate
power and authority to own or lease  its properties and conduct its business  as
described  in the Registration Statement; all the issued and outstanding capital
stock of each of the  subsidiaries of the Company  has been duly authorized  and
validly  issued and is fully paid and  nonassessable and is owned by the Company
free and clear  of all liens,  encumbrances and security  interests; and to  the
best  of  such counsel's  knowledge,  no options,  warrants  or other  rights to
purchase, agreements or other  obligations to issue or  other rights to  convert
any  obligations into  shares of  capital stock  or ownership  interests in such
subsidiaries are outstanding;

        (ii)
       the authorized capital stock of the Company consists of 2,000,000  shares
       of  Preferred Stock,  $.01 par value,  of which there  are no outstanding
shares and 20,000,000 shares of Common Stock, $.01 par value, of which there are
outstanding 16,173,696 shares (including the Underwritten Stock plus the  number
of  shares  of  Option  Stock  issued  on  the  date  hereof;  proper  corporate
proceedings have been taken validly to authorize such authorized capital  stock;
all  of the outstanding shares of such capital stock (including the Underwritten
Stock and the shares of  Option Stock issued on the  Closing Date, if any)  have
been  duly and validly issued  and are fully paid  and nonassessable; any Option
Stock purchased after the  Closing Date, when issued  and delivered to and  paid
for  by the  Underwriters as provided  in the Underwriting  Agreement, will have
been duly and validly issued  and will be fully  paid and nonassessable; and  no
preemptive rights of, or rights of first refusal in favor of, stockholders exist
with  respect  to the  Stock, or  the issue  and sale  thereof, pursuant  to the
Certificate of Incorporation or Bylaws of  the Company and, to the knowledge  of
such  counsel, there  are no  contractual preemptive  rights that  have not been
waived, rights of first refusal or rights of co-sale which exist with respect to
the issue and sale of the Stock;

       (iii)
       the Registration Statement has become effective under the Securities  Act
       and,  to the best  of such counsel's knowledge,  no stop order suspending
the effectiveness of the Registration Statement or suspending or preventing  the
use of the Prospectus is in effect and no proceedings for that purpose have been
instituted or are pending or contemplated by the Commission;

        (iv)
       the Registration Statement and the Prospectus (except as to the financial
       statements  and schedules and other  financial data contained therein, as
to which such counsel need express no opinion) comply as to form in all material
respects with the requirements of the Securities Act, the Exchange Act and  with
the rules and regulations of the Commission thereunder;

         (v)
       such  counsel have no  reason to believe  that the Registration Statement
       (except as to the financial statements and schedules and other  financial
and statistical data contained or incorporated by reference therein, as to which
such  counsel need  not express  any opinion  or belief)  at the  Effective Date
contained any untrue statement of a material fact or omitted to state a material
fact required to be stated therein  or necessary to make the statements  therein
not  misleading, or that  the Prospectus (except as  to the financial statements
and schedules and other financial and statistical data contained or incorporated
by reference therein, as to which such  counsel need not express any opinion  or
belief) as of its date or at the Closing Date (or any later date on which Option
Stock  is purchased), contained  or contains any untrue  statement of a material
fact or omitted or omits to state a material fact necessary in order to make the
statements therein, in light  of the circumstances under  which they were  made,
not misleading;

        (vi)
       the information required to be set forth in the Registration Statement in
       answer  to Items 9 and 10 (insofar as it relates to such counsel) of Form
S-3 is to the best of such counsel's knowledge
<PAGE>
accurately and  adequately set  forth therein  in all  material respects  or  no
response  is  required with  respect to  such Items,  and, to  the best  of such
counsel's knowledge, the  description of  the Company's stock  option plans  set
forth  or  incorporated by  reference in  the  Prospectus accurately  and fairly
presents the information  required to be  shown with respect  to said plans  and
options  to  the  extent  required  by the  Securities  Act  and  the  rules and
regulations of the Commission thereunder;

       (vii)
       such counsel do not know of any franchises, contracts, leases,  documents
       or legal proceedings, pending or threatened, which in the opinion of such
counsel  are  of  a  character  required to  be  described  in  the Registration
Statement or the Prospectus  or to be  filed as exhibits  to or incorporated  by
reference  in the Registration  Statement, which are not  described and filed or
incorporated by reference as required;

      (viii)
       the  Underwriting  Agreement  has  been  duly  authorized,  executed  and
       delivered by the Company;

        (ix)
       the  issue and sale by the Company of the shares of Stock as contemplated
       by the Underwriting  Agreement will  not conflict  with, or  result in  a
breach  of, the Certificate of Incorporation or  Bylaws of the Company or any of
its subsidiaries or any agreement or  instrument known to such counsel to  which
the  Company or  any of  its subsidiaries is  a party  or any  applicable law or
regulation or so far as is known to such counsel, any order, writ, injunction or
decree, of any jurisdiction, court or governmental instrumentality;

         (x)
       all  holders  of  securities  of   the  Company  having  rights  to   the
       registration  of shares of Common Stock,  or other securities, because of
the filing of the Registration Statement by the Company have waived such  rights
or such rights have expired by reason of lapse of time following notification of
the Company's intent to file the Registration Statement;

        (xi)
       no consent, approval, authorization or order of any court or governmental
       agency  or  body is  required for  the  consummation of  the transactions
contemplated in the Underwriting  Agreement, except such  as have been  obtained
under  the Securities Act and such as  may be required under state securities or
blue sky laws in connection with the  purchase and distribution of the Stock  by
the Underwriters; and

       (xii)
       the  Stock will  be duly  authorized for  listing by  the Nasdaq National
       Market upon official notice of issuance.

    In addition to the matters set forth above, counsel rendering the  foregoing
opinion  shall also include a  statement to the effect  that nothing has come to
the attention of such counsel that  leads them to believe that the  Registration
Statement  (except  as  to  the financial  statements  and  schedules  and other
financial data contained or incorporated by reference therein, as to which  such
counsel  need not express any opinion or belief) at the Effective Date contained
any untrue statement  of a material  fact or  omitted to state  a material  fact
required  to be stated therein  or necessary to make  the statements therein not
misleading, or that the  Prospectus (except as to  the financial statements  and
schedules  and  other  financial  data contained  or  incorporated  by reference
therein, as to which such counsel need not express any opinion or belief) as  of
its  date or at  the Closing Date  (or any later  date on which  Option Stock is
purchased), contained or  contains any untrue  statement of a  material fact  or
omitted  or  omits to  state  a material  fact necessary  in  order to  make the
statements therein, in light  of the circumstances under  which they were  made,
not misleading.

    Re: Registration Statement on Form S-3

Ladies and Gentlemen:

    We  have examined the Registration Statement on Form S-3 filed by Burr-Brown
Corporation (the "Company")  with the  Securities and  Exchange Commission  (the
"Commission")  on even date herewith, as thereafter amended or supplemented (the
"Registration  Statement"),  in  connection  with  the  registration  under  the
Securities Act of 1933, as amended, of shares of the Company's Common Stock (the
"Shares").  The Shares include  an over-allotment option  to the Underwriters to
purchase additional shares of the Company's Common  Stock and are to be sold  to
the  Underwriters as described  in the Registration Statement  for resale to the
public. As your counsel  in connection with this  transaction, we have  examined
the proceedings taken and are familiar with the proceedings proposed to be taken
by you in connection with the sale and issuance of the Shares.

    It  is our opinion that,  upon conclusion of the  proceedings being taken or
contemplated by us, as your  counsel, to be taken prior  to the issuance of  the
Shares  and upon completion  of the proceedings  being taken in  order to permit
such transactions to be  carried out in accordance  with the securities laws  of
the  various states  where required,  the Shares,  when issued  and sold  in the
manner described  in the  Registration Statement,  will be  legally and  validly
issued, fully paid and nonassessable.

    We  consent to the  use of this  opinion as an  exhibit to said Registration
Statement, and further consent to the use of our name wherever appearing in said
Registration Statement, including  the prospectus constituting  a part  thereof,
and in any amendment or supplement thereto.

                                          Very truly yours,

                                          BROBECK, PHLEGER & HARRISON
