  % CONVERTIBLE SUBORDINATED NOTES DUE 2005

   
The     %  Convertible  Subordinated  Notes  due  2005  (the  "Notes")  of  VLSI
Technology, Inc. ("VLSI" or the "Company") offered hereby will mature on October
1,  2005. Interest on the Notes is payable on April 1 and October 1 of each year
commencing April 1, 1996. The Notes are convertible into shares of Common Stock,
$.01 par value per share (the "Common Stock"), of the Company at any time on  or
before  the close of business on the  last trading day prior to maturity, unless
previously redeemed, at  a conversion price  of $        per  share, subject  to
adjustment in certain events as described herein.
    

   
The  Common  Stock  of the  Company  is  quoted on  the  Nasdaq  National Market
("Nasdaq") under the symbol "VLSI." On September 6, 1995, the last reported sale
price of the Common Stock on Nasdaq  was $34.375 per share. See "Price Range  of
Common Stock and Dividend Policy." The Company intends to apply for approval for
quotation of the Notes on the Nasdaq Stock Market under the symbol "VLSIG."
    

   
The Notes are subordinated in right of payment to all existing and future Senior
Debt  (as defined) of  the Company and effectively  subordinated to all existing
and future liabilities and obligations of the Company's subsidiaries. As of June
30, 1995, the total principal  amount of Senior Debt  of the Company would  have
been  approximately $64.2  million (not  including the  Company's 7% Convertible
Subordinated Debentures due 2012, which were converted or redeemed subsequent to
June  30,  1995)  and  other  liabilities  and  obligations  of  the   Company's
subsidiaries  (excluding intercompany indebtedness)  that would have effectively
ranked senior to  the Notes  would have  been approximately  $33.9 million.  The
Notes  are redeemable, in whole or in part,  at the option of the Company at any
time on or after October 3, 1997, at the redemption prices set forth herein plus
accrued interest, except that the Notes may not be redeemed prior to October  3,
1999  unless the  closing price  of the  Common Stock  is at  least 125%  of the
conversion price for at least 20 trading days within a period of 30  consecutive
trading  days ending on the fifth trading day prior to the notice of redemption.
No sinking fund is provided for the Notes. In addition, following the occurrence
of a Designated Event (i.e., a Change of Control or Termination of Trading (each
as defined)), each holder  has the right  to cause the  Company to purchase  the
Notes  at  101%  of their  principal  amount  together with  accrued  and unpaid
interest. See "Description of Notes."
    

SEE "RISK FACTORS" COMMENCING AT PAGE 7 FOR A DISCUSSION OF CERTAIN FACTORS THAT
SHOULD BE CONSIDERED BY PURCHASERS OF THE NOTES.

THESE SECURITIES HAVE  NOT BEEN APPROVED  OR DISAPPROVED BY  THE SECURITIES  AND
EXCHANGE  COMMISSION OR ANY  STATE SECURITIES COMMISSION  NOR HAS THE SECURITIES
AND EXCHANGE  COMMISSION OR  ANY  STATE SECURITIES  COMMISSION PASSED  UPON  THE
ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A
CRIMINAL OFFENSE.

products  and in bringing them to  market rapidly. VLSI's target markets include
the computing,  communications  and  consumer and  entertainment  markets.  VLSI
emphasizes  high  performance  applications  where  its  products  are  critical
elements of complex electronic systems. VLSI  targets key OEM customers who  are
leaders  in their respective  industries. The Company's  major customers include
Compaq, Apple, Ericsson, Hewlett-Packard, Silicon Graphics, Tellabs and Alcatel.

    VLSI produces a significant portion of its wafers (approximately 79% in  the
first   half  of  1995)  at  its   own  facilities  and  augments  its  internal
manufacturing  capacity  with   the  foundry  services   of  third-party   wafer
subcontractors.  The  Company  believes  that  this  strategy  improves quality,
cost-effectiveness, responsiveness to customers, access to capacity, ability  to
implement  leading edge  process technology and  time to market,  as compared to
semiconductor companies  that  lack fabrication  facilities.  The  semiconductor
industry   is,  however,   currently  facing   capacity  constraints   in  wafer
manufacturing and the availability of third-party wafer foundries has diminished
significantly. Due to this manufacturing capacity shortage, as well as increased
customer demand,  the  Company  is  seeking  to  accelerate  the  expansion  and
upgrading of its internal and external manufacturing capacity. The Company is in
the  process  of completing  the build-out  of its  fabrication facility  in San
Antonio, Texas in  order to  increase its internal  manufacturing capacity.  The
Company  has  taken  steps to  secure  deliveries of  long  lead-time equipment,
including steppers,  necessary  to  support  approximately  a  50%  increase  in
internal  wafer starts from the fourth quarter  of 1995 to the fourth quarter of
1996.

    Through its subsidiary,  COMPASS Design Automation,  Inc. ("COMPASS"),  VLSI
offers  an  integrated suite  of electronic  design automation  ("EDA") software
tools, foundry-flexible libraries and  support services for  use by systems  and
circuit  designers at other  semiconductor and systems companies,  as well as at
the Company, in creating complex integrated circuits.

    The Company's principal executive offices  are located at 1109 McKay  Drive,
San  Jose,  California  95131,  and  the  Company's  telephone  number  is (408)
434-3100.

                               RECENT DEVELOPMENT

    On August  25,  1995, Intel  Corporation  exercised  in full  a  warrant  to
purchase  2,677,604 shares of VLSI Common  Stock for an aggregate exercise price
of approximately $31.3 million. See "Risk  Factors -- Effect of Potential  Stock
Sales."

- ---------------
(1)  From 1990 through  1993, VLSI's fiscal  year end was  the last Saturday  of
     December.  In 1994,  the Company  changed its fiscal  year end  to the last
     Friday of December. The actual dates  of the Company's fiscal year ends  in
     the  table above  are December  29, 1990,  December 28,  1991, December 26,
     1992, December  25, 1993  and  December 30,  1994.  The fiscal  year  ended
     December  30, 1994 was a 53-week year. The current fiscal year is a 52-week
     year ending on December 29, 1995.

(2)  Includes a special charge of $12.8 million reflecting the estimated cost of
     corporate reorganization related to exiting the memory business.

(3)  Includes a special charge  of $22.5 million related  to the de-emphasis  of
     older  technologies,  costs  of streamlining  sales  distribution channels,
     costs of relocating certain offices, writedowns of nonperforming assets and
     costs associated with intellectual property matters.

(4)  Includes a  special charge  of  $1.0 million  representing a  write-off  of
     purchased  in-process  research  and development  expenses  related  to the
     acquisition of certain assets.

(5)  The six-month period  ended July  1, 1994 was  comprised of  27 weeks.  The
     six-month period ended June 30, 1995 was comprised of 26 weeks.

(6)  Includes  a  charge  of $19.4  million  relating to  litigation.  See "Risk
     Factors -- TI Litigation; Intellectual  Property Matters" and "Business  --
     Litigation."

(7)  EBITDA  is defined as  earnings before interest  income and other expenses,
     interest expense, taxes on income, depreciation and amortization. EBITDA is
     presented here  to  provide  additional  information  about  the  Company's
     ability  to meet its  future debt service,  capital expenditure and working
     capital requirements and should not be  construed as a substitute for or  a
     better  indicator of results of operations  or liquidity than net income or
     cash flow from operating activities  computed in accordance with  generally
     accepted  accounting principles. EBITDA  for the six  months ended June 30,
     1995 includes a charge of $19.4  million relating to litigation. See  "Risk
     Factors  -- TI Litigation; Intellectual  Property Matters" and "Business --
     Litigation."

(8)  Includes capitalized interest;  excludes additions to  property, plant  and
     equipment financed by capital leases.

(9)  The  ratio of earnings to fixed charges is computed by dividing (x) the sum
     of income  before  provision  for  income taxes  and  fixed  charges,  less
     capitalized  interest,  by  (y)  fixed charges.  Fixed  charges  consist of
     interest on all indebtedness, amortization of debt expense and discount  or
     premium  relating to indebtedness  and the estimated  interest component of
     rental expense.

(10) As a result of the loss incurred  for the years 1990 and 1992, the  Company
     was  unable  to  fully cover  fixed  charges.  The dollar  amounts  of such
     deficiencies in  1990  and  1992  were $12.7  million  and  $31.6  million,
     respectively.

(11) Pro forma as adjusted ratios assume (i) the redemption or conversion of the
     Company's   7%   Convertible   Subordinated   Debentures   due   2012  (the
     "Debentures") after June 30, 1995 as  if such redemption or conversion  had
     been  consummated as of  the first day  of each fiscal  period and (ii) the
     sale of the Notes offered hereby and receipt of the estimated net  proceeds
     (assuming  no exercise  of the  Underwriters' over-allotment  option) as if
     such actions  had been  consummated as  of  the first  day of  each  fiscal
     period.

(12) Gives effect to the conversion or redemption of all of the Debentures after
     June 30, 1995.

(13) Adjusted  to reflect the conversion or  redemption of all of the Debentures
     after June  30, 1995  and the  sale of  the Notes  offered hereby  and  the
     receipt   of  the  estimated  net   proceeds,  assuming  the  Underwriters'
     over-allotment option is not exercised.

                                  RISK FACTORS

   
    AN  INVESTMENT  IN  THE  NOTES  INVOLVES A  SIGNIFICANT  DEGREE  OF  RISK. A
PROSPECTIVE INVESTOR SHOULD CONSIDER CAREFULLY ALL OF THE INFORMATION  CONTAINED
IN  THIS  PROSPECTUS  BEFORE DECIDING  WHETHER  TO  PURCHASE THE  NOTES  AND, IN
PARTICULAR, SHOULD CONSIDER THE FOLLOWING FACTORS.
    

   
    FLUCTUATIONS IN OPERATING  RESULTS.   The Company believes  that its  future
operating  results will  be subject  to quarterly  variations based  upon a wide
variety of  factors, including  the cyclical  nature of  both the  semiconductor
industry  and the  markets addressed by  the Company's  products, price erosion,
competitive factors, fluctuations  in manufacturing  yields, the  timing of  new
product  introductions, changes in  product mix, the  availability and extent of
utilization  of  manufacturing   capacity,  product  obsolescence,   scheduling,
rescheduling  and  cancellation  of large  orders,  the ability  to  develop and
implement new  technologies,  changes  in effective  tax  rates  and  litigation
expenses.  The Company's  COMPASS subsidiary,  like other  companies in  the EDA
business, is particularly subject to significant fluctuations in revenues due to
limited backlog and its reliance on large orders placed late in the quarter. The
Company  increases  its   level  of   operating  expenses   and  investment   in
manufacturing  capacity in  anticipation of  future growth  in revenues.  To the
extent this revenue growth does not materialize, the Company's operating results
would be adversely affected. In circumstances where the Company is operating  at
less  than  full  capacity or  has  targeted  a market  segment  as  a long-term
strategic focus, the Company may choose, in the face of severe pricing pressure,
to manufacture products at low or no profitability. The Company's second quarter
financial results were adversely affected by a $19.4 million charge to  earnings
relating  to a May 1995  verdict against VLSI in  a patent infringement lawsuit.
See  "--  TI  Litigation;  Intellectual  Property  Matters"  and  "Business   --
Litigation."
    

    MANUFACTURING  CAPACITY LIMITATIONS.  The Company's manufacturing facilities
are operating at  capacity. As a  result, VLSI's growth  is constrained and  the
Company  has experienced difficulty  in meeting the  delivery dates requested by
customers. Although the Company intends to use the proceeds of this offering  to
increase  manufacturing  capacity,  there  can be  no  assurance  that  any such
increased capacity  will  be sufficient  to  satisfy demand  for  its  products.
Prolonged  inability of VLSI to deliver products in a timely manner could result
in the loss of customers and materially adversely affect results of  operations.
In addition, the Company is experiencing manufacturing inefficiencies associated
with the operation of its facilities at capacity while simultaneously working to
expand  or upgrade that  capacity. Significant lead time  is required to acquire
and install  additional wafer  fabrication  equipment. To  the extent  that  the
Company  is unable to procure and install such equipment in a timely manner, the
increase in wafer production capacity at its facilities would be delayed.

   
    In addition, available third-party wafer fabrication, assembly, testing  and
packaging  capacity has become very limited in recent months. The Company relied
on two outside suppliers for approximately  27% and 21% of its wafer  production
in  1994 and  the first  half of  1995, respectively.  Although the  Company has
ongoing relationships with these  suppliers, the Company  has only one  contract
for  guaranteed capacity.  The other supplier  has notified the  Company that it
will reduce its allocation of wafers to VLSI in the third quarter of 1995,  with
further  reductions from  the second quarter  of 1995 levels  through the second
quarter of 1996, and has indicated that  it does not intend to supply wafers  to
the  Company thereafter. There can  be no assurance that  such supplier will not
further reduce  its  allocation to  VLSI.  The  Company is  attempting  to  find
alternative  sources of wafer  supply. In addition, the  Company relies on three
suppliers  for  almost  all  assembly  operations.  Any  material  reduction  in
shipments  by the  Company's key  suppliers could  also have  a material adverse
effect on  the Company's  results of  operations. As  the Company  is  currently
unable  to  meet the  demands of  its  customers for  VLSI's products,  which is
adversely impacting the  businesses of the  Company's customers, some  customers
are  actively seeking to second source products currently obtained from VLSI. In
addition, VLSI's relationships with key customers may be negatively affected  by
the  Company's  inability to  meet  customer demands,  potentially  resulting in
material adverse impacts on the Company's future operating results.
    

    MANUFACTURING RISKS.  The fabrication of integrated circuits is an extremely
complex and  precise  process  consisting  of hundreds  of  separate  steps  and
requiring production in a highly controlled, clean

                                       7
<PAGE>
environment.  Minute impurities, errors in any  step of the fabrication process,
defects in the  masks used to  print circuits on  a wafer or  other factors  can
cause  a substantial percentage of wafers to be rejected or numerous die on each
wafer to  be nonfunctional.  The Company  may experience  problems in  achieving
acceptable  yields in the manufacture of wafers, particularly in connection with
any expansion of its capacity or change in its processing steps. For example, in
late 1992, the Company switched processes at one step in the manufacturing line,
which caused certain  VLSI chips  to fail.  The Company's  replacement of  these
chips  at no charge to the customers adversely affected results of operations in
the first quarter of 1993.

    In  addition  to  manufacturing  in  its  own  facilities,  VLSI  has  wafer
manufacturing  arrangements with two integrated circuit manufacturing companies.
These wafer subcontractors are  themselves subject to  all of the  manufacturing
risks  that are  applicable to  VLSI's own  wafer manufacturing  operations. The
Company also subcontracts virtually all of its integrated circuit packaging  and
a  significant portion of  its final testing to  third parties, principally ANAM
Industrial Company in Korea, ASE  Corporation in Taiwan, Advanced  Semiconductor
Assembly  Technology in Hong Kong and Mitsui Incorporated in Japan. In addition,
the Company's  foreign subcontract  manufacturing  arrangements are  subject  to
risks  such as changes in  government policies, transportation delays, increased
tariffs, fluctuations in foreign  exchange rates, and  export and tax  controls.
Any  problems experienced in obtaining acceptable  wafers from third party wafer
subcontractors on a timely basis to augment the Company's internal manufacturing
capacity or in the  integrated circuit packaging,  assembly and test  operations
performed  by subcontractors could delay shipments of the Company's products and
materially adversely affect the Company's results of operations.

    The Company's success  is also  dependent upon  its ability  to develop  and
implement  new  manufacturing  process  technologies.  Semiconductor  design and
process methodologies are subject to rapid technological change, requiring large
expenditures for research and  development. Most of  the Company's products  are
currently  manufactured using  sub-micron CMOS  processes. The  Company believes
that the transition to smaller  geometry process technologies will be  important
to  remaining  competitive.  The Company  is  in  the process  of  expanding and
upgrading  its  manufacturing  facility  in  San  Jose,  California  to  convert
production  to a 6-inch CMOS wafer  process. The Company's San Antonio facility,
which is  currently using  both 0.6-micron  and 0.8-micron  processes, is  being
converted to 100% 0.5-micron CMOS process capability and steps to facilitize the
third   and  fourth  modules  have  begun.   In  the  second  quarter  of  1995,
inefficiencies caused  by  the  work  associated with  the  conversions  of  the
manufacturing  facilities had a  negative effect on  the Company's overall gross
profit of approximately $2 million, or one percentage point of gross margin. The
work effort  associated with  the changes  to these  facilities will  negatively
affect  the Company's gross profit in the third quarter of 1995, could result in
further disruption to  manufacturing output as  well as wafer  yields and  could
have a material adverse impact on future operating results.

    The  Company is party  to a joint development  agreement with Hitachi, which
expires in 1997. Under such agreement, the Company and Hitachi work together  to
develop   advanced  sub-micron  processes  for  the  manufacture  of  integrated
circuits. In addition,  the Company is  dependent on Hitachi  for assistance  in
developing  other  state-of-the-art  manufacturing  processes.  Any  failure  or
disruption of the Company's joint  development activities could have a  material
adverse   effect  upon  the  Company's  ability  to  implement  state-of-the-art
manufacturing processes.

    The Company's San Jose  facility, which accounted  for approximately 41%  of
its  total internal production in the first  half of 1995, is located near major
earthquake faults and  in an area  that has  in the recent  past experienced  an
extended  drought.  Even though  the Company  utilizes  both of  its fabrication
plants and two subcontractors to manufacture  its wafers and has the ability  to
shift  manufacturing  from  one  plant  to another  for  many  of  its products,
disruption of operations at either of the Company's production facilities or  at
those  of its subcontractors for  any reason, such as  fire or earthquake, would
cause delays in shipments  until the Company could  shift the products from  the
affected facility or subcontractor to another facility.

    FUTURE CAPITAL NEEDS.  Semiconductor companies such as VLSI have substantial
ongoing  capital  requirements  to  obtain  internal  or  external manufacturing
capacity. In order  to remain  competitive, the  Company must  continue to  make
significant  investments in  capital equipment  and expansion  of facilities, as
well  as  in  research  and  development.  Development  and  implementation   of
sub-micron  manufacturing processes is particularly capital intensive, requiring
significant investments in new state-of-the-art equipment. The Company currently
has budgeted its capital expenditures for 1995 to be approximately $200 million.
The Company believes that the net proceeds of approximately $94 million from the
sale of the Common Stock in the Company's public offering in June 1995, together
with existing  cash balances,  cash flow  from operations,  available  equipment
financing and net proceeds of this Notes offering will be sufficient to meet the
Company's  liquidity and capital requirements through 1996. While the Company is
currently increasing  its  internal  manufacturing capacity  by  completing  the
build-out  of its  San Antonio  facility, the Company  believes it  will need to
further expand its internal capacity as  well as to explore methods to  increase
external  capacity. As a result,  the Company may be  required or choose to seek
additional equity or debt financing to fund further expansion of its internal or
external wafer fabrication capacity or for other purposes. The timing and amount
of such capital requirements cannot be precisely determined and will depend on a
number of factors,  including demand  for the Company's  products, product  mix,
changes  in semiconductor industry conditions and competitive factors. There can
be no assurance that such additional financing will be available when needed or,
if available, will  be on satisfactory  terms. The failure  to obtain  financing
would  hinder the  Company's ability  to make  continued investments  in capital
equipment and facilities, which could materially adversely affect the  Company's
results of operations.
    

   
    TI  LITIGATION; INTELLECTUAL PROPERTY MATTERS.   The Company is one of three
defendants in a major patent infringement suit brought by Texas Instruments with
respect to patents that have now expired, which suit resulted in a May 1995 jury
verdict against VLSI  for damages of  $19.4 million and  a determination by  the
jury  that the infringement  was intentional. As  a result of  such verdict, the
Company recorded a charge to earnings of $19.4 million in the second quarter  of
1995. However, in August 1995, the trial judge overturned and set aside the jury
verdict  and conditionally granted a  new trial on the  matter in the event that
his decision is reversed on  appeal. It is anticipated  that TI will appeal  the
judge's  reversal of  the jury verdict  and seek  enhanced damages, pre-judgment
interest and attorneys' fees.  In the event that  TI's appeal is successful  and
enhanced  damages  (which  by  statute  may  be  as  high  as  treble  damages),
pre-judgment interest and/or  attorneys' fees  are awarded,  the judgment  could
result  in a material reduction  in liquidity, as well  as an additional adverse
impact on  the  Company's  reported  results of  operations.  See  "Business  --
Litigation."
    

    The semiconductor industry is generally characterized by vigorous protection
and  pursuit  of  intellectual  property rights  and  positions,  which  have on
occasion resulted in  protracted litigation  that utilizes  cash and  management
resources,  which can  have a significant  adverse effect  on operating results.
There can be no assurance that additional intellectual property claims will  not
be  made against  the Company  in the  future or  that the  Company will  not be
prohibited from using the technologies subject to such claims or be required  to
obtain  licenses and make corresponding royalty payments for past or future use.
There can  be  no  assurance  that  any  such  licenses  could  be  obtained  on
commercially reasonable terms.

    DEPENDENCE  ON PERSONAL COMPUTER INDUSTRY.  The Company estimates that total
sales to the personal  computer market during  1994 and the  first half of  1995
represented   approximately  47%  and   46%  of  the   Company's  net  revenues,
respectively. With seven of the Company's top ten customers in the first half of
1995 operating in the  personal computer industry,  a deterioration of  business
conditions  in  the personal  computer industry  would  have a  material adverse
effect on VLSI's  operations. The personal  computer market is  volatile and  is
subject  to  significant  shifts  in demand  and  severe  pricing  pressures. In
addition,  the  market   for  the   Company's  personal   computer  devices   is
characterized  by  rapid  technological  change  and  product  obsolescence. The
Company's results in the personal computer market will also be dependent in part
on the Company's ability to respond quickly to new microprocessor  architectures
adopted  by  major  OEMs.  The Company's  need  to  anticipate  customer product
transitions also leads  to potential inventory  exposure, which could  adversely
affect the Company's financial results.

    CYCLICAL  NATURE OF THE SEMICONDUCTOR  INDUSTRY.  The semiconductor industry
has historically been characterized by  wide fluctuations in product supply  and
demand.  From  time  to  time, the  industry  has  also  experienced significant
downturns, often in connection with, or in anticipation of, declines in  general
economic  conditions. These downturns, which in  some cases have lasted for more
than a year, have  been characterized by  diminished product demand,  production
over-capacity  and subsequent accelerated  erosion of average  sales prices. The
Company historically  has  experienced  prolonged  over-capacity  for  sustained
periods  of time  and there can  be no  assurance that the  Company's efforts to
increase manufacturing capacity will not  result in future sustained periods  of
over-capacity.   The  Company,  like   other  semiconductor  manufacturers  with
fabrication facilities, has  high fixed costs  for its manufacturing  facilities
and  believes that its operating results were adversely affected by an industry-
wide downturn in the demand for semiconductors in 1990. This downturn  coincided
with  the recession in the U.S. economy and slower growth in various electronics
industries using semiconductors, including market segments in which the  Company
was engaged at the time.

    NEW  PRODUCT RISKS.  The Company's future  success depends on its ability to
continue to develop and introduce new  products that compete effectively on  the
basis  of  price and  performance and  that  satisfy customer  requirements. The
Company expects to  continue to invest  in the research  and development of  new
products  for all of its market segments during the balance of 1995. New product
development often requires long-term  forecasting of market trends,  development
and  implementation of  new processes  and technologies  and substantial capital
commitments. If the Company is unable to design, develop, manufacture and market
new products successfully and in a timely manner, its operating results will  be
materially  adversely affected.  No assurance  can be  given that  the Company's
product and process development efforts will be successful or that new  products
will  achieve market acceptance. For  example, the Company expended considerable
financial and  technical resources  during  1993 and  part  of 1994  toward  the
development  of its Polar  product, a device intended  for the handheld computer
market integrating  Intel's 386SL  microprocessor. Because  the handheld  market
developed  more slowly  than initial  expectations, the  Company and  Intel, its
partner in  the  Polar  development  effort,  canceled  the  Polar  project  and
terminated the amended July 8, 1992 Technology Agreement between the companies.

    COMPETITION.  The semiconductor industry in general and the markets in which
the  Company competes in  particular are intensely  competitive, exhibiting both
rapid technological change and ongoing price erosion as technologies mature. The
Company  competes  with   large  domestic  and   foreign  companies  that   have
substantially  greater financial, technical,  marketing and management resources
than the  Company, such  as AT&T,  IBM, Intel,  LSI, Motorola,  TI and  Toshiba.
Competition  is particularly intense in X86 core  logic chip sets where Intel, a
dominant supplier of microprocessors  to the PC industry,  has become the  major
supplier  of Pentium PC chip  sets, as well as  motherboards, which is likely to
cause increased pricing and margin pressure on such chip sets. Competition faced
by COMPASS  in the  EDA market  comes  primarily from  a few  large  established
vendors,  such as Cadence  and Mentor Graphics.  There is no  assurance that the
Company will be able to compete successfully in the future.

    CONCENTRATION OF CUSTOMER BASE.   Approximately two-thirds of the  Company's
net  revenues for the first half  of 1995 were derived from  sales to its top 20
customers, a large percentage of which are in the personal computer business. As
a  result  of  the  concentration  of  the  Company's  customer  base,  loss  or
cancellation  of business from any of these major customers, significant changes
in scheduled deliveries to any of these customers or decreases in the prices  of
products  sold to any  of these customers could  materially adversely affect the
Company's results  of  operations. These  risks  of customer  concentration  are
exacerbated by the fact that the Company's agreements with its customers for the
purchase  of products are generally terminable by such customers at any time and
permit customers to cancel orders  previously placed for the Company's  products
without  penalty.  For example,  in  the fourth  quarter  of 1993,  Apple, which
accounted for  19%  of 1993  net  revenues,  postponed and,  in  certain  cases,
canceled  approximately $20 million of shipments originally planned for delivery
in 1994, adversely  affecting VLSI's  1994 results of  operations. Shipments  to
another  customer, Compaq, accounted for 22% of  net revenues in 1994 and 11% of
net revenues in the first six months of 1995.

    SUBORDINATION OF NOTES.   The Notes  will be unsecured  and subordinated  in
right  of payment in full to all existing and future Senior Debt of the Company.
As a result of such subordination, in the event of

                                       10
<PAGE>
bankruptcy,  liquidation  or  reorganization  of   the  Company,  or  upon   the
acceleration  of any Senior Debt, the assets of the Company will be available to
pay obligations on the Notes only after  all Senior Debt has been paid in  full,
and  there may not be  sufficient assets remaining to pay  amounts due on any or
all of the  Notes then outstanding.  The Company  expects from time  to time  to
incur  indebtedness constituting  Senior Debt.  The Notes  are also structurally
subordinated to  the liabilities,  including trade  payables, of  the  Company's
subsidiaries.  The  Indenture  does  not prohibit  or  limit  the  incurrence of
additional  indebtedness,  including  Senior  Debt,   by  the  Company  or   its
subsidiaries and the incurrence of additional indebtedness by the Company or its
subsidiaries could adversely affect the Company's ability to pay its obligations
on  the Notes.  As of June  30, 1995,  the Company would  have had approximately
$64.2 million of Senior  Debt outstanding (not  including the Debentures,  which
were converted or redeemed subsequent to June 30, 1995) and the indebtedness and
all  other  liabilities of  the  Company's subsidiaries  (excluding intercompany
indebtedness) would have been approximately  $33.9 million. See "Description  of
Notes -- Subordination."

   
    LIMITATIONS ON REPURCHASE OF NOTES.  Upon a Designated Event, which includes
a  Change of Control and a Termination of Trading (each as defined), each holder
of Notes  will have  certain rights,  at  the holder's  option, to  require  the
Company  to repurchase all or a portion  of such holder's Notes. If a Designated
Event were to  occur, there  can be  no assurance  that the  Company would  have
sufficient  funds to  pay the  repurchase price  for all  Notes tendered  by the
holders thereof. In addition,  a Designated Event would  constitute an event  of
default  under the  Company's existing  credit agreement  and the  repurchase of
Notes as a result of a Designated Event would be prohibited by the terms of such
credit agreement  unless consented  to  by the  banks. Moreover,  the  Company's
repurchase  of Notes as a result of the  occurrence of a Designated Event may be
prohibited or limited  by, or create  an event  of default under,  the terms  of
agreements  related to  other borrowings which  the Company may  enter into from
time  to  time,  including  other  agreements  relating  to  Senior  Debt.   See
"Description  of  Notes --  Repurchase at  Option of  Holders Upon  a Designated
Event."
    

    AVAILABILITY OF RAW  MATERIALS.   Raw materials essential  to the  Company's
business  are  generally  available  from  multiple  sources.  However,  due  to
increased levels of demand, there may be an industrywide shortage of raw silicon
wafers. A  prolonged  inability  to  obtain silicon  wafers  or  any  other  raw
materials could have a material adverse impact on the Company's business.

    ENVIRONMENTAL  REGULATIONS.  The Company is subject to a variety of federal,
state and local governmental regulations related to the storage, use,  discharge
and  disposal of  toxic, volatile or  otherwise hazardous chemicals  used in its
manufacturing process.  Increasing  public attention  has  been focused  on  the
environmental  impact of  semiconductor manufacturing  operations. The Company's
San Jose, California facilities are located near residential areas, which  could
increase  the incidence of environmental complaints or investigations. There can
be no assurance that  changes in environmental regulations  will not impose  the
need  for additional capital equipment or other requirements. Any failure by the
Company to  control the  use of,  or adequately  to restrict  the discharge  of,
hazardous  substances under present or future  regulations could subject VLSI to
substantial  liability  or  could  cause  its  manufacturing  operations  to  be
suspended. Such liability or suspension of manufacturing operations could have a
material adverse effect on the Company's operating results.

   
    ABSENCE  OF PUBLIC MARKET FOR THE  NOTES.  The Notes will  be a new issue of
securities with no established trading market. The Underwriters have advised the
Company that  they  currently  intend  to  make  a  market  in  the  Notes.  The
Underwriters  are not obligated, however, to make a market in the Notes, and any
such market making may be discontinued at any time at the sole discretion of the
Underwriters without notice. While  the Company currently  intends to apply  for
approval  for the Notes to be quoted on the Nasdaq Stock Market, there can be no
assurance that a trading market  for the Notes will  develop or, if such  market
does develop, as to the liquidity of such market.
    

    VOLATILITY  OF STOCK PRICE.  The  Company's Common Stock has experienced and
can be expected  to experience  substantial price volatility.  In addition,  the
stock market in general has experienced

                                       11
<PAGE>
extreme  price  and volume  fluctuations, which  have particularly  affected the
market price of many technology companies and which have often been unrelated to
the operating performance of those companies.  See "Price Range of Common  Stock
and Dividend Policy."

    EFFECT OF POTENTIAL STOCK SALES.  Intel has the right to demand registration
of  2,677,604 shares  of VLSI  Common Stock  (the "Warrant  Shares") issued upon
exercise of a warrant in August 1995. Such registration rights may be  exercised
by  Intel at any time. In the event that Intel exercises its demand registration
rights, the  Company will  be required  to file  a registration  statement  with
respect to the Warrant Shares with the Securities and Exchange Commission within
30  days of Intel's notice to VLSI,  subject to certain conditions. There can be
no assurance  that Intel  will not  elect to  exercise its  demand  registration
rights  during or  shortly after this  offering, which  election could adversely
affect the market price of the Company's  Common Stock. In addition, as of  June
30,  1995, approximately 3.2 million vested and unvested shares of the Company's
Common Stock (the "Option Shares") were  subject to employee and director  stock
options  having exercise prices below the market price of the Common Stock shown
on the cover  page of  this Prospectus. Many  optionees may  choose to  exercise
their  options and sell  the Common Stock  acquired upon exercise  in the coming
months due to  the significant spread  between the exercise  prices and  current
market  prices. Sales of large  numbers of shares by  Intel, optionees or others
may have a depressing effect on the market price for the Company's Common Stock.
See "Capitalization."

                                USE OF PROCEEDS

    The net proceeds to the  Company from the sale  of Notes offered hereby  are
estimated  to be  approximately $146,000,000 ($167,937,500  if the Underwriters'
over-allotment option is exercised in full). The proceeds will be used primarily
for adding  internal and  external wafer  fabrication capacity  and for  general
corporate  purposes,  including  working  capital.  In  particular,  the Company
intends to  install  additional  manufacturing equipment  and  to  complete  the
build-out  of  its San  Antonio fabrication  facility to  increase manufacturing
capacity. Although the Company does not currently intend to use the proceeds  of
this  offering for the acquisition of  the business, products or technologies of
other  companies,  it  may  in  the  future  enter  into  agreements  for   such
acquisitions.  There  are  no  pending  agreements  or  arrangements  concerning
material acquisitions. Pending such uses, the Company intends to invest the  net
proceeds in investment grade securities and interest-bearing obligations.

                PRICE RANGE OF COMMON STOCK AND DIVIDEND POLICY

   
    The  Company's Common Stock  has been traded  on the over-the-counter market
under the Nasdaq symbol  "VLSI" since the Company's  initial public offering  in
1983.  The following table sets  forth, for the periods  indicated, the high and
low closing prices for the Common Stock on the Nasdaq National Market. The  last
reported  sale price for the Common Stock of the Company on September 6, 1995 as
reported by the Nasdaq National  Market is set forth on  the cover page of  this
Prospectus.  At August 31, 1995, the Company  had 1,489 holders of record of its
Common Stock  and  46,838,737 shares  outstanding.  See also  "Risk  Factors  --

    The  Company has never paid cash dividends  on its Common Stock. The Company
presently intends to retain all cash for  use in the operation and expansion  of
the  Company's business and does not anticipate paying any cash dividends in the
near future. Certain of VLSI's debt agreements prohibit the payment of dividends
without the lender's consent.

(1)  From 1990  through 1993, VLSI's  fiscal year  end was the  last Saturday of
    December. In  1994, the  Company changed  its fiscal  year end  to the  last
    Friday  of December. The actual  dates of the Company's  fiscal year ends in
    the table above are December 29, 1990, December 28, 1991, December 26, 1992,
    December 25, 1993 and December 30, 1994. The fiscal year ended December  30,
    1994 was a 53-week year. The current fiscal year is a 52-week year ending on
    December 29, 1995.

(2)  During 1994, the Company reclassified  costs associated with its Technology
    Centers from  research  and development  to  cost of  sales  and  marketing,
    general  and  administrative  in  order  to  make  the  presentation  of the
    Company's financial statements more comparable with the financial statements
    of its closest competitors and to better reflect the nature of these  costs.
    Amounts reclassified in 1990, 1991, 1992, 1993 and 1994 total $18.1 million,
    $18.8 million, $19.1 million, $18.4 million and $22.7 million, respectively.
    Cost  of sales were  increased $14.1 million,  $14.7 million, $14.9 million,
    $14.2 million  and  $17.9 million  for  1990,  1991, 1992,  1993  and  1994,
    respectively.  Marketing, general and administrative expenses were increased
    $4.0 million, $4.1 million, $4.2 million, $4.2 million and $4.8 million  for
    1990, 1991, 1992, 1993 and 1994, respectively.

(3)  The six-month  period ended  July 1,  1994 was  comprised of  27 weeks. The
    six-month period ended June 30, 1995 was comprised of 26 weeks.

(4) Represents a special charge of  $12.8 million reflecting the estimated  cost
    of corporate reorganization related to exiting the memory business.

(5)  Represents a special charge of $22.5  million related to the de-emphasis of
    older technologies, costs of streamlining sales distribution channels, costs
    of relocating certain offices, writedowns of nonperforming assets and  costs
    associated with intellectual property matters.

(6)  Represents  a special  charge  of $1.0  million  reflecting a  write-off of
    purchased in-process  research  and  development  expenses  related  to  the
    acquisition of certain assets.

   
(7)  Represents  a charge  of $19.4  million relating  to litigation.  See "Risk
    Factors -- TI  Litigation; Intellectual Property  Matters" and "Business  --
    Litigation."
    

   
(8)  EBITDA is  defined as earnings  before interest income  and other expenses,
    interest expense, taxes on income, depreciation and amortization. EBITDA  is
    presented here to provide additional information about the Company's ability
    to  meet its future  debt service, capital  expenditure, and working capital
    requirements and should  not be construed  as a substitute  for or a  better
    indicator of results of operations or liquidity than net income or cash flow
    from  operating activities  computed in  accordance with  generally accepted
    accounting principles.  EBITDA  for  the  six months  ended  June  30,  1995
    includes a charge of $19.4 million relating to litigation. See "Risk Factors
    --   TI  Litigation;   Intellectual  Property  Matters"   and  "Business  --
    Litigation."
    

(9) Includes capitalized  interest; excludes  additions to  property, plant  and
    equipment financed by capital leases.

(10)  The ratio of earnings to fixed charges is computed by dividing (x) the sum
    of income  before  provision  for  income  taxes  and  fixed  charges,  less
    capitalized  interest,  by  (y)  fixed  charges.  Fixed  charges  consist of
    interest on all indebtedness, amortization  of debt expense and discount  or
    premium  relating to indebtedness,  and the estimated  interest component of
    rental expense.

   
(11) As a result of the loss incurred  for the years 1990 and 1992, the  Company
    was  unable to fully cover fixed charges. The amount of such deficiencies in
    1990 and 1992 were $12.7 million and $31.6 million, respectively.
    

(12) Pro forma as adjusted ratios assume (i) the redemption or conversion of the
    Debentures after June 30, 1995 as if such redemption or conversion had  been
    consummated  as of the first day of each  fiscal period and (ii) the sale of
    the Notes offered hereby and receipt of the estimated net proceeds (assuming
    no exercise of the Underwriters'  over-allotment option) as if such  actions
    had been consummated as of the first day of each fiscal period.

                                    BUSINESS

   
    VLSI  is a  leader in  the design,  manufacture and  sale of  highly complex
application specific integrated circuits ("ASICs") -- custom chips designed  for
an  individual customer -- and  application specific standard products ("ASSPs")
- -- semi-custom chips designed  for a particular market  application that may  be
used  by several different customers. The Company targets high-volume markets in
which it has built significant expertise and can use its library of  proprietary
cells  and highly  integrated building blocks  to assist  customers in designing
products and in bringing them to  market rapidly. VLSI's target markets  include
the  computing,  communications  and consumer  and  entertainment  markets. VLSI
emphasizes  high  performance  applications  where  its  products  are  critical
elements  of complex electronic systems. VLSI  targets key OEM customers who are
leaders in their  respective industries. The  Company's major customers  include
Compaq, Apple, Ericsson, Hewlett-Packard, Silicon Graphics, Tellabs and Alcatel.
    

   
    VLSI  produces a significant portion of its wafers (approximately 79% in the
first  half  of  1995)  at  its   own  facilities  and  augments  its   internal
manufacturing   capacity  with   the  foundry  services   of  third-party  wafer
subcontractors. The  Company  believes  that  this  strategy  improves  quality,
cost-effectiveness,  responsiveness to customers, access to capacity, ability to
implement leading edge  process technology and  time to market,  as compared  to
semiconductor  companies  that  lack fabrication  facilities.  The semiconductor
industry  is,   however,  currently   facing  capacity   constraints  in   wafer
manufacturing and the availability of third-party wafer foundries has diminished
significantly. Due to this manufacturing capacity shortage, as well as increased
customer  demand,  the  Company  is  seeking  to  accelerate  the  expansion and
upgrading of its internal and external manufacturing capacity. The Company is in
the process  of completing  the build-out  of its  fabrication facility  in  San
Antonio,  Texas in  order to increase  its internal  manufacturing capacity. The
Company has  taken  steps to  secure  deliveries of  long  lead-time  equipment,
including  steppers,  necessary  to  support  approximately  a  50%  increase in
internal wafer starts from the fourth quarter  of 1995 to the fourth quarter  of
1996.
    

    Through  its subsidiary,  COMPASS Design Automation,  Inc. ("COMPASS"), VLSI
offers an  integrated suite  of electronic  design automation  ("EDA")  software
tools,  foundry-flexible libraries and  support services for  use by systems and
circuit designers at other  semiconductor and systems companies,  as well as  at
the Company, in creating complex integrated circuits.

BUSINESS STRATEGY

    VLSI's  objective is  to design  and manufacture  highly-integrated, complex
semiconductor devices that allow  its customers to develop  and bring to  market
higher value-added systems and products. Key elements in its strategy to achieve
this objective include:

    - TARGET  HIGH-VOLUME MARKETS. VLSI targets  high-volume markets in which it
      has built significant expertise and can utilize its library of proprietary
      cells and  high-level building  blocks to  assist customers  in  designing
      products  and in bringing them to  market rapidly. VLSI believes that this
      allows the Company  to offer more  value to the  customer at higher  gross
      margins for the Company.

    - FOCUS   ON  LARGE,  INDUSTRY-LEADING  OEM   CUSTOMERS.  VLSI  focuses  its
      manufacturing and research and development  resources on products for  OEM
      customers  that  are leaders  in their  respective industries.  During the
      first half of 1995, approximately two-thirds of the Company's net revenues
      were derived from sales to its top 20 customers, including Compaq,  Apple,
      Ericsson, Hewlett-Packard, Silicon Graphics, Tellabs and Alcatel.

    - EMPHASIZE  STANDARD CELL  ASICS AND  ASSPS. VLSI  emphasizes standard cell
      ASICs and ASSPs rather  than gate arrays  and other design  methodologies.
      The  Company  believes  that  the standard  cell  approach  is  a superior
      methodology for  satisfying the  size, performance  and power  consumption
      requirements  of  the  highly  complex products  that  form  VLSI's target
      markets.

                                       17
<PAGE>
    - LEVERAGE LIBRARY OF STANDARD  CELLS TO REDUCE  CUSTOMERS' TIME TO  MARKET.
      VLSI's Functional System Block ("FSB") library, an expanding collection of
      pre-designed  cells  and high-level  building blocks,  provides frequently
      used integrated circuit  functions. The  FSB library allows  VLSI and  its
      customers  to more rapidly design and integrate products, thereby reducing
      VLSI's customers' time to market. VLSI's library of FSBs includes Graphics
      Controllers (LCD  and  CRT),  a  DES  Encryption  FSB,  a  PCI  FSB,  SCSI
      Controllers, an ARM RISC-based microprocessor (low power, high performance
      embedded   control  applications),  and  a   variety  of  FSBs  for  power
      management, communications for standards such as DECT, GSM and PHS, signal
      conversion, forward  error  correction, digital  demodulation,  MPEG2  and
      digital signal processing.

    - PROVIDE  ENGINEERING DESIGN  SUPPORT. The  Company seeks  to differentiate
      itself from its competitors not only through the quality of its  products,
      but  also through the level of its technological support and service. VLSI
      operates a network  of geographically dispersed  Technology Centers  where
      experienced  engineers with a specific technical focus work with customers
      to develop designs for new  products and to provide continuing  after-sale
      customer support. In 1993, VLSI established a Customer Excellence program,
      which  is designed to foster relationships  with customers through the use
      of teams focused on elements such as customer satisfaction,  manufacturing
      competence and technical excellence.

   
    - EMPLOY  BOTH INTERNAL AND EXTERNAL MANUFACTURING CAPACITY. VLSI produces a
      significant portion of its wafers (approximately 79% in the first half  of
      1995)  at its own facilities  and augments internal manufacturing capacity
      with the foundry services of third-party wafer subcontractors. The Company
      believes  that   this  strategy   improves  quality,   cost-effectiveness,
      responsiveness  to  customers, access  to  capacity, ability  to implement
      leading edge  process  technology  and  time to  market,  as  compared  to
      semiconductor    companies   that   lack   fabrication   facilities.   The
      semiconductor industry is, however, currently facing capacity  constraints
      in wafer manufacturing and the availability of third-party wafer foundries
      has diminished significantly. Due to this manufacturing capacity shortage,
      as well as increased customer demand, the Company is seeking to accelerate
      the  expansion and  upgrading of  its internal  and external manufacturing
      capacity. The Company is in the process of completing the build-out of its
      fabrication facility  in  San Antonio,  Texas  in order  to  increase  its
      internal  manufacturing capacity.  The Company  has taken  steps to secure
      deliveries of long lead-time  equipment, including steppers, necessary  to
      support  approximately a  50% increase in  internal wafer  starts from the
      fourth quarter of 1995 to the fourth quarter of 1996.

LITIGATION

    In  July 1990, Texas  Instruments filed two actions  against the Company and
four other defendants, Analog Devices, Inc., Integrated Device Technology,  Inc.
("IDT"),  LSI  Logic  Corporation  and  Cypress  Semiconductor  Corporation (the
Company and  such other  defendants  are collectively  referred  to as  the  "TI
Defendants"). IDT settled its cases with TI in late December 1992.

    In  the action filed before the United States International Trade Commission
("ITC"), TI sought to exclude from importation into the U.S. all TI  Defendants'
products  manufactured  outside  the  U.S.  that  allegedly  utilize  a  plastic
encapsulation process described in U.S. Patent No. 4,043,027 (the "027 patent").
On October 15, 1991, the Administrative  Law Judge ("ALJ") found the 027  patent
to  be valid  and infringed  by the  Company's old  plastic encapsulation gating
process. However, a new plastic encapsulation gating process developed and  used
by the TI Defendants was found not to infringe the 027 patent. In December 1991,
the  full ITC determined that it would  not consider TI's appeal to overturn the
ALJ's decision on noninfringement of the new process. The United States Court of
Appeals for the Federal Circuit affirmed the ITC decision in March 1993. The 027
patent has since expired.

                                       19
<PAGE>
   
    TI also filed a patent infringement action against the TI Defendants in  the
United  States  District Court  for the  Northern District  of Texas  seeking an
injunction against the sale and/or manufacture by the TI Defendants of  products
that  allegedly  infringe the  027 patent.  The action  also sought  damages for
alleged past infringement  of the  027 patent and  now expired  U.S. Patent  No.
3,716,764.  A trial for this matter was held  in April 1995, which resulted in a
May 1995  jury  verdict  against  VLSI  for  damages  of  $19.4  million  and  a
determination  by the jury that the infringement was intentional. As a result of
such verdict, the Company recorded a charge to earnings of $19.4 million in  the
second  quarter of 1995. However, in August 1995, the trial judge overturned and
set aside the jury verdict and conditionally  granted a new trial on the  matter
in  the event his decision is reversed on appeal. It is anticipated that TI will
appeal the  judge's reversal  of the  jury verdict  and seek  enhanced  damages,
pre-judgment  interest and  attorneys' fees.  In the  event that  TI's appeal is
successful and  enhanced damages  (which by  statute may  be as  high as  treble
damages), pre-judgment interest and/or attorneys' fees are awarded, the judgment
could  result in  a material  reduction in liquidity,  as well  as an additional
adverse impact  on the  Company's reported  results of  operations. Due  to  the
uncertainty  as to the  final outcome of an  appeal or a  new trial, the Company
does not currently  intend to adjust  its reserves relating  to this  litigation
matter.

                              DESCRIPTION OF NOTES

   
    The  Notes will be issued under an indenture to be dated as of September   ,
1995 (the "Indenture") between the Company and Harris Trust and Savings Bank, as
trustee (the "Trustee"), a  copy of which  has been filed as  an exhibit to  the
Registration  Statement of which this Prospectus forms  a part. The terms of the
Notes will include those stated  in the Indenture and those  made a part of  the
Indenture  by reference  to the  Trust Indenture  Act of  1939, as  amended (the
"TIA"), as in effect on the date of the Indenture. The Notes will be subject  to
all  such terms, and holders of the Notes  are referred to the Indenture and the
TIA for a statement of such terms. The following is a summary of important terms
of the Notes and does  not purport to be complete.  Reference should be made  to
all  provisions of the  Indenture, including the  definitions therein of certain
terms and  all terms  made a  part of  the Indenture  by reference  to the  TIA.
Certain  definitions of terms used in the  following summary are set forth under
"-- Certain Definitions"  below. As used  in this section,  the "Company"  means
VLSI  Technology,  Inc., but  not any  of its  Subsidiaries, unless  the context
requires otherwise.
    

GENERAL

    The Notes will be general unsecured subordinated obligations of the Company,
will mature on October 1, 2005 (the "Maturity Date"), and will be limited to  an
aggregate  principal amount  of $150,000,000 ($172,500,000  if the Underwriters'
over-allotment option is exercised). The  Notes will be issued in  denominations
of  $1,000 and integral multiples of $1,000  in fully registered form. The Notes
are exchangeable  and  transfers  thereof will  be  registrable  without  charge
therefor,  but the Company may require payment  of a sum sufficient to cover any
tax or other governmental charge in connection therewith.

   
    The Notes will accrue interest at a rate of   % per annum from September   ,
1995, or from the most recent interest  payment date to which interest has  been
paid  or duly  provided for,  and accrued  and unpaid  interest will  be payable
semi-annually in arrears on April 1 and  October 1 of each year beginning  April
1,  1996.  Interest  will be  paid  to the  person  in  whose name  the  Note is
registered at the close of business on the March 15 or September 15  immediately
preceding  the relevant interest payment date (other than with respect to a Note
or portion thereof called for redemption on a redemption date, or repurchased in
connection with a Designated Event on a repurchase date, during the period  from
a  record date to (but excluding) the  next succeeding interest payment date (in
which case  accrued interest  shall  be payable  (unless  such Note  of  portion
thereof  is converted) to the holder of  the Note or portion thereof redeemed or
repurchased)). Interest  will  be  computed  on the  basis  of  a  360-day  year
comprised of twelve 30-day months.
    

    Principal  of, premium, if any, and interest on the Notes will be payable at
the office or  agency of  the Company  maintained for  such purpose  or, at  the
option  of the Company, payment  of interest may be made  by check mailed to the
holders of the Notes at their respective addresses set forth in the register  of
holders  of  Notes. Until  otherwise designated  by  the Company,  the Company's
office or agency  maintained for such  purpose will be  the principal  corporate
trust office of the Trustee.

CONVERSION

   
    The  holders of Notes will be entitled at any time on or before the close of
business on  the last  trading day  prior to  the Maturity  Date of  the  Notes,
subject  to prior  redemption or  repurchase, to  convert any  Notes or portions
thereof (in denominations of $1,000 or  multiples thereof) into Common Stock  of
the  Company, at the conversion price of $    per share of Common Stock, subject
to adjustment as described below  (the "Conversion Price"). Except as  described
below,  no  adjustment will  be made  on  conversion of  any Notes  for interest
accrued thereon or for dividends on any Common Stock issued. If Notes not called
for redemption are converted after a record date for the payment of interest and
prior to  the  next  succeeding  interest  payment  date,  such  Notes  must  be
accompanied  by funds equal to the  interest payable on such succeeding interest
payment date on the principal amount  so converted. The Company is not  required
to issue fractional shares of Common Stock upon conversion of Notes and, in lieu
thereof,  will pay a cash  adjustment based upon the  market price of the Common
Stock on the last
    

                                       21
<PAGE>
   
trading day prior to  the date of  conversion. In the case  of Notes called  for
redemption,  conversion  rights will  expire  at the  close  of business  on the
trading day preceding the date fixed for redemption, unless the Company defaults
in payment of  the redemption  price, in which  case the  conversion right  will
terminate  at the close  of business on the  date such default  is cured. In the
event any holder exercises  its repurchase right upon  a Designated Event,  such
holder's  conversion  right  will terminate.  See  "-- Repurchase  at  Option of
Holders Upon a Designated Event."
    

    The right of conversion attaching to any Note may be exercised by the holder
by  delivering  the  Note  at  the  specified  office  of  a  conversion  agent,
accompanied  by a duly signed and  completed notice of conversion, together with
any funds that  may be  required as described  in the  preceding paragraph.  The
conversion  date  shall be  the  date on  which the  Note,  the duly  signed and
completed notice of conversion, and any funds that may be required as  described
in  the preceding paragraph shall have been  so delivered. A holder delivering a
Note for conversion will not be required  to pay any taxes or duties payable  in
respect  of the  issue or delivery  of Common  Stock on conversion,  but will be
required to pay any tax or duty which may be payable in respect of any  transfer
involved  in the issue or delivery of the  Common Stock in a name other than the
holder of the Note. Certificates representing shares of Common Stock will not be
issued or delivered unless all taxes and  duties, if any, payable by the  holder
have been paid.

   
    The  Conversion Price is subject to  adjustment (under formulae set forth in
the Indenture) in certain events, including: (i) the issuance of Common Stock as
a dividend  or  distribution  on  Common Stock  of  the  Company;  (ii)  certain
subdivisions  and combinations  of the Common  Stock; (iii) the  issuance to all
holders of Common Stock of certain rights or warrants to purchase Common  Stock;
(iv) the dividend or other distribution to all holders of Common Stock of shares
of  capital  stock of  the Company  (other  than Common  Stock) or  evidences of
indebtedness of the Company of assets (including securities, but excluding those
rights, warrants, dividends  and distributions referred  to above and  dividends
and  distributions in connection with the liquidation, dissolution or winding up
of  the  Company  or  paid  exclusively   in  cash);  (v)  dividends  or   other
distributions  consisting  exclusively of  cash (excluding  any cash  portion of
distributions referred to in clause (iv)) to all holders of Common Stock to  the
extent  such  distributions,  combined  together  with  (A)  all  such  all-cash
distributions made  within  the preceding  12  months  in respect  of  which  no
adjustment  has been made plus  (B) any cash and the  fair market value of other
consideration payable in respect of any tender  offers by the Company or any  of
its  Subsidiaries for Common  Stock concluded within the  preceding 12 months in
respect of  which no  adjustment has  been made,  exceeds 15%  of the  Company's
market capitalization (being the product of the then current market price of the
Common Stock times the number of shares of Common Stock then outstanding) on the
record  date  for  such distribution;  and  (vi)  the purchase  of  Common Stock
pursuant to a tender offer made by the Company or any of its subsidiaries to the
extent that the aggregate consideration, together with (X) any cash and the fair
market value  of any  other  consideration payable  in  any other  tender  offer
expiring  within 12 months  preceding such tender  offer in respect  of which no
adjustment has been  made plus  (Y) the aggregate  amount of  any such  all-cash
distributions  referred to in  clause (v) above  to all holders  of Common Stock
within the 12 months preceding the expiration of such tender offer in respect of
which no  adjustments  have been  made,  exceeds  15% of  the  Company's  market
capitalization on the expiration of such tender offer.
    

    The  Indenture will provide that, in the  event of the occurrence of certain
events affecting the rights (the "Rights") distributed pursuant to the Company's
First Amended  and Restated  Stockholder Rights  Plan, as  amended (the  "Rights
Plan"), appropriate adjustments to the Conversion Price will be made. In lieu of
any  such adjustment, the Company may amend the Rights Plan to provide that upon
conversion of the  Notes the  holder thereof will  receive, in  addition to  the
Common  Stock issuable upon  such conversion, the Rights  which attached to such
shares of Common Stock or would have  attached to such shares if the Rights  had
not  become separated from  the Common Stock  pursuant to the  provisions of the
Rights Plan.

    In the case of  (i) any reclassification  or change of  the Common Stock  or
(ii)  a consolidation, merger or combination involving  the Company or a sale or
conveyance to another corporation of the property

                                       22
<PAGE>
and assets of the  Company as an  entirety or substantially  as an entirety,  in
each  case as  a result of  which holders of  Common Stock shall  be entitled to
receive stock, other securities, other property or assets (including cash)  with
respect  to or in exchange for such Common  Stock, the holders of the Notes then
outstanding will be entitled thereafter to convert such Notes into the kind  and
amount  of shares of stock, other securities  or other property or assets, which
they would have owned  or been entitled to  receive upon such  reclassification,
change,  consolidation, merger, combination,  sale or conveyance  had such Notes
been converted into  Common Stock  immediately prior  to such  reclassification,
change,  consolidation, merger, combination, sale  or conveyance (assuming, in a
case in which the Company's stockholders may exercise rights of election, that a
holder of Notes would not have exercised any rights of election as to the stock,
other securities or other property or assets receivable in connection  therewith
and  received per share the kind and amount received per share by a plurality of
non-electing shares). Certain  of the  foregoing events may  also constitute  or
result  in a Designated Event  requiring the Company to  offer to repurchase the
Notes. See "-- Repurchase at Option of Holders Upon a Designated Event."

    In the event of a taxable distribution to holders of Common Stock (or  other
transaction)  which  results  in any  adjustment  of the  Conversion  Price, the
holders of Notes  may, in certain  circumstances, be deemed  to have received  a
distribution subject to United States income tax as a dividend; in certain other
circumstances,  the  absence  of such  an  adjustment  may result  in  a taxable
dividend to  the  holders of  Common  Stock.  See "Certain  Federal  Income  Tax
Considerations."

    The  Company from time to  time may, to the  extent permitted by law, reduce
the Conversion Price of the  Notes by any amount for  any period of at least  20
days,  in which  case the Company  shall give at  least 15 days'  notice of such
decrease, if the Board of Directors has made a determination that such  decrease
would  be in  the best  interests of the  Company, which  determination shall be
conclusive. The  Company  may,  at  its option,  make  such  reductions  in  the
Conversion    Price,   in    addition   to    those   set    forth   above,   as
the Board of Directors deems  advisable to avoid or  diminish any income tax  to
holders of Common Stock resulting from any dividend or distribution of stock (or
rights  to  acquire stock)  or from  any event  treated as  such for  income tax
purposes. See "Certain Federal Income Tax Considerations."

    No  adjustment  in  the  Conversion  Price  will  be  required  unless  such
adjustment would require a change of at least 1% of the Conversion Price then in
effect; provided that any adjustment that would otherwise be required to be made
shall  be carried forward  and taken into account  in any subsequent adjustment.
Except as  stated above,  the Conversion  Price  will not  be adjusted  for  the
issuance  of Common Stock or any securities convertible into or exchangeable for
Common Stock or carrying the right to purchase any of the foregoing.

SUBORDINATION

    The payment of principal of, premium, if any, and interest on the Notes will
be subordinated in right of payment, as set forth in the Indenture, to the prior
payment in full  of all  Senior Debt,  whether outstanding  on the  date of  the
Indenture  or thereafter  incurred. Upon  any distribution  to creditors  of the
Company in  a liquidation  or dissolution  of the  Company or  in a  bankruptcy,
reorganization,  insolvency, receivership or similar  proceeding relating to the
Company or  its property,  an assignment  for the  benefit of  creditors or  any
marshalling  of the Company's assets and liabilities, the holders of Senior Debt
will be entitled to  receive payment in  full of all  obligations in respect  of
such  Senior Debt before  the holders of  Notes will be  entitled to receive any
payment with respect to the Notes.

   
    In the  event of  any  acceleration of  the Notes  because  of an  Event  of
Default,  the holders of any  Senior Debt then outstanding  would be entitled to
payment in full of  all obligations in  respect of such  Senior Debt before  the
holders  of the  Notes are  entitled to receive  any payment  or distribution in
respect thereof. The Indenture  will further require  that the Company  promptly
notify  holders of Senior Debt if payment of the Notes is accelerated because of
an Event of Default.
    

   
    The Company also may not make any payment upon or in respect of the Notes if
(i) a default in  the payment of  the principal of,  premium, if any,  interest,
rent or other obligations in respect of Senior Debt
    

                                       23
<PAGE>
occurs and is continuing beyond any applicable period of grace or (ii) any other
default  occurs and  is continuing with  respect to Designated  Senior Debt that
permits holders of the Designated Senior  Debt as to which such default  relates
to  accelerate its maturity and the Trustee receives a notice of such default (a
"Payment Blockage Notice") from  the Company or other  person permitted to  give
such  notice under the Indenture. Payments on the Notes may and shall be resumed
(a) in the case  of a payment default,  upon the date on  which such default  is
cured or waived and (b) in case of a nonpayment default, the earlier of the date
on  which such nonpayment default is cured or  waived or 179 days after the date
on which the applicable  Payment Blockage Notice is  received. No new period  of
payment  blockage may be  commenced unless and  until (i) 365  days have elapsed
since the effectiveness  of the  immediately prior Payment  Blockage Notice  and
(ii)  all scheduled payments of principal, premium,  if any, and interest on the
Notes that have come due have been  paid in full in cash. No nonpayment  default
that  existed or was continuing on the  date of delivery of any Payment Blockage
Notice to the Trustee shall be, or  be made, the basis for a subsequent  Payment
Blockage Notice.

    By  reason of the subordination provisions  described above, in the event of
the Company's  liquidation or  insolvency, holders  of Senior  Debt may  receive
more,  ratably, and  holders of  the Notes may  receive less,  ratably, than the
other creditors  of  the  Company.  Such  subordination  will  not  prevent  the
occurrences of any Event of Default under the Indenture.

    The  Notes are obligations exclusively of  the Company. Since the operations
of the Company are partially conducted  through Subsidiaries, the cash flow  and
the consequent ability to service debt, including the Notes, of the Company, are
partially  dependent upon the earnings of  its Subsidiaries and the distribution
of those  earnings  to, or  upon  loans or  other  payments of  funds  by  those
Subsidiaries  to, the Company. The payment of  dividends and the making of loans
and advances to the Company by its  Subsidiaries may be subject to statutory  or
contractual  restrictions, are dependent upon the earnings of those Subsidiaries
and are subject to various business considerations.

    Any right of the Company to receive  assets of any of its Subsidiaries  upon
their  liquidation or reorganization (and the consequent right of the holders of
the Notes to participate  in those assets) will  be effectively subordinated  to
the claims of that Subsidiary's creditors (including trade creditors), except to
the  extent  that  the  Company  is itself  recognized  as  a  creditor  of such
Subsidiary, in which case the claims  of the Company would still be  subordinate
to  any security interests in the assets of such Subsidiary and any indebtedness
of such Subsidiary senior to that held by the Company.

    As of  June  30,  1995,  the Company  had  approximately  $64.2  million  of
indebtedness  outstanding  that would  have  constituted Senior  Debt (excluding
accrued interest and Senior Debt constituting liabilities of a type not required
to be reflected as a liability on the balance sheet of the Company in accordance
with GAAP and  not including the  Debentures, which were  converted or  redeemed
subsequent  to June 30, 1995).  As of June 30,  1995, there was also outstanding
approximately  $33.9   million  of   indebtedness  and   other  obligations   of
Subsidiaries  of the Company (excluding intercompany liabilities and liabilities
of a type not required  to be reflected as a  liability on the balance sheet  of
such subsidiaries in accordance with GAAP) as to which the Notes would have been
structurally subordinated. The Indenture will not limit the amount of additional
indebtedness, including Senior Debt, which the Company can create, incur, assume
or  guarantee, nor will the Indenture limit the amount of indebtedness and other
liabilities which any Subsidiary can create, incur, assume or guarantee.

    In the event that, notwithstanding the foregoing, the Trustee or any  holder
of  Notes receives any payment  or distribution of assets  of the Company of any
kind in contravention of  any of the  terms of the  Indenture, whether in  cash,
property  or  securities, including,  without limitation  by  way of  set-off or
otherwise, in respect of the Notes before all Senior Debt is paid in full,  then
such  payment or  distribution will be  held by  the recipient in  trust for the
benefit of  holders  of  Senior Debt,  and  will  be immediately  paid  over  or
delivered   to  the   holders  of  Senior   Debt  or   their  representative  or
representatives to the extent  necessary to make payment  in full of all  Senior
Debt  remaining  unpaid,  after  giving  effect  to  any  concurrent  payment or
distribution, or provision therefor, to or for the holders of Senior Debt.

                                       24
<PAGE>
OPTIONAL REDEMPTION

   
    The Notes may be  redeemed at the  option of the Company,  in whole or  from
time to time in part, on and after October 3, 1997, on not less than 15 nor more
than  60 days' prior written notice to  the holders thereof by first class mail,
at the  following  redemption  prices (expressed  as  percentages  of  principal
amount)  if redeemed during the 12-month period beginning October 1 of each year
indicated (October 3 with respect to 1997), plus accrued and unpaid interest  to
the  date  fixed for  redemption; provided,  however, that  the Company  may not
redeem the Notes prior to October 3, 1999 unless the closing price of the Common
Stock on the principal  stock exchange or  market on which  the Common Stock  is
then  quoted or  admitted to  trading equals or  exceeds 125%  of the Conversion
Price for at least  20 trading days  within a period  of 30 consecutive  trading
days  ending on the fifth trading day prior to the date the notice of redemption
is first mailed to the holders of the Notes:

</TABLE>

    If less than all the Notes are to be redeemed, the Trustee will select Notes
for redemption  pro rata  or by  lot or  by any  other method  that the  Trustee
considers  fair and appropriate. The Trustee may select for redemption a portion
of the principal of any Note that  has a denomination larger than $1,000.  Notes
and  portions  thereof will  be redeemed  in  the amount  of $1,000  or integral
multiples of $1,000. The Trustee will make the selection from Notes  outstanding
and not previously called for redemption.

    Provisions  of the Indenture  that apply to the  Notes called for redemption
also apply to portions of the Notes called for redemption. If any Note is to  be
redeemed  in  part, the  notice  of redemption  will  state the  portion  of the
principal amount to be redeemed.  Upon surrender of a  Note that is redeemed  in
part  only,  the Company  will  execute and  the  Trustee will  authenticate and
deliver to the holder  a new Note  equal in principal  amount to the  unredeemed
portion of the Note surrendered.

    On  and after the redemption  date, unless the Company  shall default in the
payment of the redemption price, interest will cease to accrue on the  principal
amount  of the  Notes or  portions thereof called  for redemption  and for which
funds have been set apart for payment. In the case of Notes or portions  thereof
redeemed  on  a redemption  date which  is also  a regularly  scheduled interest
payment date, the interest payment due on such date shall be paid to the  person
in  whose name the Note  is registered at the close  of business on the relevant
record date.

REPURCHASE AT OPTION OF HOLDERS UPON A DESIGNATED EVENT

   
    Upon the occurrence of  a Designated Event, each  holder of Notes will  have
the  right to require the Company to repurchase all or any part (equal to $1,000
or an integral multiple  thereof) of such holder's  Notes pursuant to the  offer
described  below (the "Designated Event Offer") at  an offer price in cash equal
to 101%  of the  aggregate  principal amount  thereof  plus accrued  and  unpaid
interest  thereon  to the  date of  purchase  (the "Designated  Event Payment").
Within 20 days following any Designated Event, the Company will mail a notice to
each holder  describing  the transaction  or  transactions that  constitute  the
Designated  Event and  offering to repurchase  Notes pursuant  to the procedures
required by the Indenture and described in such notice.
    

   
    The Company  will comply  with  the requirements  of  Rule 14e-1  under  the
Exchange  Act and  any other securities  laws and regulations  thereunder to the
extent  such  laws  and  regulations  are  applicable  in  connection  with  the
repurchase  of the Notes as a result of a Designated Event. Rule 13e-4 under the
    

                                       25
<PAGE>
   
Exchange  Act  requires,  among  other  things,  the  dissemination  of  certain
information  to security holders in the event  of an issuer tender offer and may
apply in the event  that the repurchase option  becomes available to holders  of
the  Notes. The Company will  comply with this rule  to the extent applicable at
that time.
    

    On the  date specified  for payment  of the  Designated Event  Payment  (the
"Designated  Event Payment Date"),  the Company will, to  the extent lawful, (1)
accept for payment all Notes or  portions thereof properly tendered pursuant  to
the Designated Event Offer, (2) deposit with the paying agent an amount equal to
the  Designated Event  Payment in  respect of all  Notes or  portions thereof so
tendered and (3) deliver or  cause to be delivered to  the Trustee the Notes  so
accepted  together with an Officers' Certificate stating the aggregate principal
amount of Notes or portions thereof  being purchased by the Company. The  paying
agent  will promptly  mail to  each holder of  Notes so  accepted the Designated
Event Payment for  such Notes, and  the Trustee will  promptly authenticate  and
mail  (or cause to be transferred by book entry) to each holder a new Note equal
in principal amount to any unpurchased portion of the Notes surrendered, if any;
PROVIDED that each such new Note will be  in a principal amount of $1,000 or  an
integral multiple thereof.

   
    The  foregoing provisions would not necessarily  afford holders of the Notes
protection in the event of highly leveraged or other transactions involving  the
Company that may adversely affect holders.
    

   
    The  right  to require  the Company  to repurchase  Notes as  a result  of a
Designated Event could have  the effect of delaying,  deferring or preventing  a
Change  of Control or  other attempts to  acquire control of  the Company unless
arrangements have been made to enable the Company to repurchase all the Notes at
the repurchase  date. Consequently,  this  right may  render more  difficult  or
discourage  a merger, consolidation or tender offer (even if such transaction is
supported  by  the  Company's  Board  of  Directors  or  is  favorable  to   the
stockholders),  the assumption of  control by a  holder of a  large block of the
Company's shares and the removal of incumbent management.
    

    Except as described above with respect to a Designated Event, the  Indenture
does not contain provisions that permit the holders of the Notes to require that
the  Company  repurchase  or  redeem  the Notes  in  the  event  of  a takeover,
recapitalization or similar restructuring. Subject to the limitation on  mergers
and   consolidations  described  below,  the  Company,  its  management  or  its
Subsidiaries could in  the future,  enter into  certain transactions,  including
refinancings,  certain  recapitalizations,  acquisitions,  the  sale  of  all or
substantially all  of its  assets, the  liquidation of  the Company  or  similar
transactions,  that would not constitute a Designated Event under the Indenture,
but that would increase  the amount of Senior  Debt (or any other  indebtedness)
outstanding  at such  time or  substantially reduce  or eliminate  the Company's
assets. There are  no restrictions in  the Indenture on  the creation of  Senior
Debt   (or  any  other  indebtedness)  and,  under  certain  circumstances,  the
incurrence of  significant  amounts of  additional  indebtedness could  have  an
adverse  effect on the Company's ability  to service its indebtedness, including
the Notes.

   
    The Credit Agreement  currently prohibits  the Company  from purchasing  any
Notes  and also provides that a Designated Event as well as certain other change
of control  events  with respect  to  the  Company would  constitute  a  default
thereunder.  Any future credit agreements or other agreements relating to Senior
Debt to which the Company becomes  a party may contain similar restrictions  and
provisions. In the event a Designated Event occurs at a time when the Company is
prohibited  from purchasing  Notes, the  Company could  seek the  consent of its
lenders to the purchase  of Notes or could  attempt to refinance the  borrowings
that  contain such prohibition. If the Company does not obtain such a consent or
repay such  borrowings,  the Company  would  remain prohibited  from  purchasing
Notes.  In such  case, the  Company's failure  to purchase  tendered Notes would
constitute an  Event  of Default  under  the  Indenture which  would,  in  turn,
constitute  a further default under the Credit Agreement. In such circumstances,
the subordination provisions in the Indenture would likely restrict payments  to
the holders of Notes.
    

    A  "Designated  Event" will  be deemed  to  have occurred  upon a  Change of
Control or a Termination of Trading.

                                       26
<PAGE>
    A "Change of Control" will be deemed to have occurred when: (i) any "person"
or "group" (as such terms are used  in Sections 13(d) and 14(d) of the  Exchange
Act)  is or becomes the "beneficial owner"  (as defined in Rules 13d-3 and 13d-5
under the Exchange  Act) of shares  representing more than  50% of the  combined
voting  power of the  then outstanding securities entitled  to vote generally in
elections of  directors  of  the  Company ("Voting  Stock"),  (ii)  the  Company
consolidates  with or merges into any  other corporation, or conveys, transfers,
or leases all or  substantially all of  its assets to any  person, or any  other
corporation  merges into the Company, and, in  the case of any such transaction,
the outstanding Common Stock of the Company is changed or exchanged as a result,
unless the stockholders of the Company immediately before such transaction  own,
directly  or  indirectly  immediately  following such  transaction,  at  least a
majority of the combined  voting power of the  outstanding voting securities  of
the  corporation  resulting  from  such transaction  in  substantially  the same
proportion as  their  ownership of  the  Voting Stock  immediately  before  such
transaction,  or (iii)  any time  the Continuing  Directors do  not constitute a
majority of  the  Board  of Directors  of  the  Company (or,  if  applicable,  a
successor  corporation to the Company); PROVIDED  that a Change of Control shall
not be deemed to have occurred if either  (x) the last sale price of the  Common
Stock  for  any  five  trading  days during  the  ten  trading  days immediately
preceding the Change  of Control is  at least  equal to 105%  of the  Conversion
Price in effect on the date of such Change of Control or (y) at least 90% of the
consideration (excluding cash payments for fractional shares) in the transaction
or  transactions constituting the Change of Control consists of shares of common
stock that are, or  upon issuance will  be, traded on  a United States  national
securities  exchange  or  approved  for  trading  on  an  established  automated
over-the-counter trading market in the United States.

   
    The definition of Change of Control includes a phrase relating to the lease,
transfer or  conveyance of  "all or  substantially  all" of  the assets  of  the
Company. Although there is a developing body of case law interpreting the phrase
"substantially  all," there is  no precise established  definition of the phrase
under applicable law. Accordingly, the ability  of a holder of Notes to  require
the  Company  to repurchase  such  Notes as  a result  of  a lease,  transfer or
conveyance of less than all  of the assets of the  Company to another person  or
group may be uncertain.
    

    "Continuing Directors" means, as of any date of determination, any member of
the  Board of Directors  of the Company  who (i) was  a member of  such Board of
Directors on the date  of the Indenture  or (ii) was  nominated for election  or
elected  to  such Board  of Directors  with the  approval of  a majority  of the
Continuing Directors  who  were  members of  such  Board  at the  time  of  such
nomination or election.

   
    A  "Termination of Trading"  will be deemed  to have occurred  if the Common
Stock (or  other common  stock into  which the  Notes are  then convertible)  is
neither  listed for trading on a  United States national securities exchange nor
approved for trading on an established automated over-the-counter trading market
in the United States.
    

MERGER AND CONSOLIDATION

    The Indenture will  provide that the  Company may not  consolidate or  merge
with or into (whether or not the Company is the surviving corporation), or sell,
assign, transfer, lease, convey or otherwise dispose of all or substantially all
of  its properties  or assets  in one or  more related  transactions, to another
corporation, person or  entity as an  entirety or substantially  as an  entirety
unless  (a) the Company is the surviving corporation or the entity or the person
formed by  or surviving  any such  consolidation or  merger (if  other than  the
Company) or to which such sale, assignment, transfer, lease, conveyance or other
disposition  shall have been  made is a corporation  organized or existing under
the laws of the United  States, any state thereof  or the District of  Columbia;
(b) the entity or person formed by or surviving any such consolidation or merger
(if  other  than  the Company)  or  the entity  or  person to  which  such sale,
assignment, transfer, lease,  conveyance or  other disposition  shall have  been
made  assumes  all  the obligations  of  the  Company under  the  Notes  and the
Indenture pursuant to a supplemental indenture in a form reasonably satisfactory
to the Trustee; (c)  immediately after such transaction  no Default or Event  of
Default  exists; and (d) the Company or  such person shall have delivered to the
Trustee an officers' certificate  and an opinion of  counsel, each stating  that
such  transaction and the  supplemental indenture comply  with the Indenture and
that all conditions precedent in the Indenture relating to such transaction have
been satisfied.

                                       27
<PAGE>
    For purposes of the foregoing, the  transfer (by lease, assignment, sale  or
otherwise,  in  a  single  transaction  or series  of  transactions)  of  all or
substantially all of the properties or assets of one or more Subsidiaries of the
Company, the capital stock of which constitutes all or substantially all of  the
properties  and assets of the Company, shall be deemed to be the transfer of all
or substantially all of the properties and assets of the Company.

    Upon any such  consolidation, merger, sale,  assignment, conveyance,  lease,
transfer  or other disposition  in accordance with  the foregoing, the successor
person formed by such consolidation  or into which the  Company is merged or  to
which such sale, assignment, conveyance, lease, transfer or other disposition is
made  will succeed to, and be substituted  for, and may exercise every right and
power of,  the Company  under the  Indenture with  the same  effect as  if  such
successor  had been named as the Company  therein, and thereafter (except in the
case of a sale,  assignment, transfer, lease,  conveyance or other  disposition)
the  predecessor corporation  will be  relieved of  all further  obligations and
covenants under the Indenture and the Notes.

EVENTS OF DEFAULT AND REMEDIES

   
    An Event of  Default is defined  in the  Indenture as being  (i) default  in
payment  of the principal of,  or premium, if any, on  the Notes, whether or not
such payment is  prohibited by  the subordination provisions  of the  Indenture;
(ii) default for 30 days in payment of any installment of interest on the Notes,
whether or not such payment is prohibited by the subordination provisions of the
Indenture;  (iii)  default  by the  Company  for  60 days  after  notice  in the
observance or performance of any other covenants in the Indenture; (iv)  default
in  the payment of  the Designated Event Payment  in respect of  the Note on the
date therefor, whether or  not such payment is  prohibited by the  subordination
provisions  of  the  Indenture;  (v)  failure  to  provide  timely  notice  of a
Designated Event; (vi) failure of the Company or any Material Subsidiary to make
any payment at maturity,  including any applicable grace  period, in respect  of
indebtedness  for borrowed money of, or guaranteed or assumed by, the Company or
any Material Subsidiary which payment is  in an amount in excess of  $25,000,000
and  continuance of such failure for 30  days after notice; (vii) default by the
Company or any Material Subsidiary with respect to any such indebtedness,  which
default  results in the  acceleration of any  such indebtedness of  an amount in
excess of $25,000,000 without such  indebtedness having been discharged or  such
acceleration  having been cured, waived, rescinded or annulled for 30 days after
notice;  or   (viii)  certain   events  involving   bankruptcy,  insolvency   or
reorganization of the Company or any Material Subsidiary.
    

    If  an Event of Default (other than  an Event of Default specified in clause
(viii) above with respect to the Company) occurs and is continuing, then and  in
every such case the Trustee, by written notice to the Company, or the holders of
not  less than 25% in aggregate principal  amount of the then outstanding Notes,
by written  notice  to the  Company  and the  Trustee,  may declare  the  unpaid
principal of, premium, if any, and accrued and unpaid interest on, all the Notes
then  outstanding to  be due and  payable. Upon such  declaration such principal
amount, premium, if any, and accrued and unpaid interest will become immediately
due and  payable, notwithstanding  anything contained  in the  Indenture or  the
Notes  to the contrary, but subject to the provisions limiting payment described
in "-- Subordination." If any Event of Default specified in clause (viii)  above
occurs  with respect to  the Company, all  unpaid principal of,  and premium, if
any, and  accrued  and unpaid  interest  on,  the Notes  then  outstanding  will
automatically become due and payable, subject to the provisions described in "--
Subordination, " without any declaration or other act on the part of the Trustee
or any holder of Notes.

    Holders  of the Notes may  not enforce the Indenture  or the Notes except as
provided in the Indenture. Subject to  the provisions of the Indenture  relating
to the duties of the Trustee, the Trustee is under no obligation to exercise any
of  its rights or powers under the  Indenture at the request, order or direction
of any  of the  holders, unless  such holders  have offered  to the  Trustee  an
indemnity  satisfactory to it against any loss, liability or expense. Subject to
all provisions of the Indenture and applicable law, the holders of a majority in
aggregate principal  amount of  the then  outstanding Notes  have the  right  to
direct  the time, method and  place of conducting any  proceeding for any remedy
available to  the Trustee  or exercising  any trust  or power  conferred on  the
Trustee.    If   a    Default   or    Event   of    Default   occurs    and   is

                                       28
<PAGE>
continuing and is known  to the Trustee, the  Indenture requires the Trustee  to
mail  a notice of Default or  Event of Default to each  holder within 60 days of
the occurrence of such Default or Event of Default, PROVIDED, HOWEVER, that  the
Trustee  may withhold from the holders notice of any continuing Default or Event
of Default (except a Default or Event of Default in the payment of principal of,
premium, if any  or interest  on the Notes)  if it  determines that  withholding
notice  is in their interest.  The holders of a  majority in aggregate principal
amount of the Notes then  outstanding by notice to  the Trustee may rescind  any
acceleration of the Notes and its consequences if all existing Events of Default
(other than the nonpayment of principal of, premium, if any, and interest on the
Notes  which has  become due  solely by virtue  of such  acceleration) have been
cured or waived and if  the rescission would not  conflict with any judgment  or
decree  of any court of competent  jurisdiction. No such rescission shall affect
any subsequent  Default or  Event  of Default  or  impair any  right  consequent
thereto.

    In  the case  of any  Event of  Default occurring  by reason  of any willful
action (or inaction) taken (or  not taken) by or on  behalf of the Company  with
the intention of avoiding payment of the premium that the Company would have had
to  pay if  the Company  then had elected  to redeem  the Notes  pursuant to the
optional redemption provisions  of the  Indenture, an  equivalent premium  shall
also  become and be immediately  due and payable to  the extent permitted by law
upon the acceleration of the Notes. If  an Event of Default occurs prior to  any
date  on which the Company  is prohibited from redeeming  the Notes by reason of
any willful action (or  inaction) taken (or  not taken) by or  on behalf of  the
Company  with the  intention of  avoiding the  prohibition on  redemption of the
Notes prior to such date, then the premium specified in the Indenture shall also
become immediately  due and  payable to  the extent  permitted by  law upon  the
acceleration of the Notes.

    The  holders of a majority  in aggregate principal amount  of the Notes then
outstanding may, on  behalf of  the holders  of all  the Notes,  waive any  past
Default  or Event  of Default under  the Indenture and  its consequences, except
Default in the  payment of principal  of, premium,  if any, or  interest on  the
Notes (other than the non-payment of principal of, premium, if any, and interest
on  the Notes which has become due solely by virtue of an acceleration which has
been duly rescinded as provided above) or in respect of a covenant or  provision
of  the Indenture which cannot be modified or amended without the consent of all
holders of Notes.

    The Company  is required  to deliver  to the  Trustee annually  a  statement
regarding  compliance  with  the  Indenture and  the  Company  is  required upon
becoming aware of any Default or Event  of Default, to deliver to the Trustee  a
statement specifying such Default or Event of Default.

AMENDMENT, SUPPLEMENT AND WAIVER

    Except  as provided in the next  two succeeding paragraphs, the Indenture or
the Notes may be amended or supplemented  with the consent of the holders of  at
least  a majority in  principal amount of the  Notes then outstanding (including
consents obtained  in connection  with  a tender  offer  or exchange  offer  for
Notes),  and  any  existing default  or  compliance  with any  provision  of the
Indenture or  the Notes  may be  waived with  the consent  of the  holders of  a
majority  in principal amount of the  then outstanding Notes (including consents
obtained in connection with a tender offer or exchange offer for Notes).

   
    Without the consent of each holder affected, an amendment or waiver may  not
(with  respect to  any Notes  held by a  non-consenting holder):  (a) reduce the
principal amount of Notes whose holders must consent to an amendment, supplement
or waiver, (b) reduce the principal of or change the fixed maturity of any  Note
or,  other than as  set forth in  the next paragraph,  alter the provisions with
respect to the redemption  of the Notes,  (c) reduce the rate  of or change  the
time  for payment  of interest  on any Notes,  (d) waive  a Default  or Event of
Default in the payment of  principal of or premium, if  any, or interest on  the
Notes  (except a rescission  of acceleration of  the Notes by  the holders of at
least a majority in aggregate principal amount of the Notes and a waiver of  the
payment default that resulted from such acceleration), (e) make any Note payable
in  money other than  that stated in the  Indenture and the  Notes, (f) make any
change in the provisions of the  Indenture relating to waivers of past  Defaults
or  the rights of holders of Notes to receive payments of principal of, premium,
if any, or interest on the Notes, (g) waive a redemption payment with respect to
any   Note,   (h)   make   any   change   in   the   foregoing   amendment   and
    

                                       29
<PAGE>
   
waiver  provisions or  (i) except  as permitted  by the  Indenture, increase the
Conversion Price or, other than as set  forth in the next paragraph, modify  the
provisions  of the  Indenture relating  to conversion of  the Notes  in a manner
adverse to the holders thereof. In addition, any amendment to the provisions  of
Article  11 of  the Indenture (which  relate to subordination)  will require the
consent of the  holders of at  least 75%  in aggregate principal  amount of  the
Notes  then outstanding if  such amendment would adversely  affect the rights of
holders of Notes.
    

   
    Notwithstanding the foregoing, without the  consent of any holder of  Notes,
the  Company and the Trustee may amend  or supplement the Indenture or the Notes
to  (a)  cure  any   ambiguity,  defect  or   inconsistency,  (b)  provide   for
uncertificated  Notes  in addition  to or  in place  of certificated  Notes, (c)
provide for the assumption of the  Company's obligations to holders of Notes  in
the circumstances required under the Indenture as described under "-- Merger and
Consolidation," (d) provide for conversion rights of holders of Notes in certain
events  such as a consolidation,  merger or sale of  all or substantially all of
the assets of the Company, (e) reduce the Conversion Price, (f) make any  change
that  would provide any additional rights or benefits to the holders of Notes or
that does not adversely affect the legal rights under the Indenture of any  such
holder,  or (g) comply with requirements of the Commission in order to effect or
maintain the qualification of the Indenture under the TIA.
    

SATISFACTION AND DISCHARGE

    The Company may discharge  its obligations under  the Indenture while  Notes
remain  outstanding if (i) all outstanding Notes  will become due and payable at
their scheduled  maturity within  one year  or (ii)  all outstanding  Notes  are
scheduled  for redemption within one  year, and in either  case, the Company has
deposited with  the  Trustee an  amount  sufficient  to pay  and  discharge  all
outstanding  Notes on the date of their scheduled maturity or the scheduled date
of redemption.

GOVERNING LAW

    The Indenture will provide that the Notes will be governed by, and construed
in accordance with, the laws of the  State of New York without giving effect  to
applicable principles of conflicts of law.

TRANSFER AND EXCHANGE

   
    A  holder may transfer  or exchange Notes in  accordance with the Indenture.
The Registrar  and the  Trustee may  require a  holder, among  other things,  to
furnish  appropriate  endorsements and  transfer documents  and the  Company may
require a holder to pay any taxes and  fees required by law or permitted by  the
Indenture. The Company is not required to transfer or exchange any Note selected
for  redemption or repurchase. Also, the Company  is not required to transfer or
exchange any Note  for a period  of 15 days  before a selection  of Notes to  be
redeemed.
    

    The  registered holder of a Note will be  treated as the owner of it for all
purposes.

THE TRUSTEE

    The Indenture will provide that, except  during the continuance of an  Event
of  Default, the Trustee will  perform only such duties  as are specifically set
forth in the Indenture. In case an  Event of Default shall occur (and shall  not
be  cured) and holders of the Notes  have notified the Trustee, the Trustee will
be required  to exercise  its powers  with the  degree of  care and  skill of  a
prudent  person in  the conduct  of such person's  own affairs.  Subject to such
provisions, the Trustee is under no obligation to exercise any of its rights  or
powers under the Indenture at the request of any of the holders of Notes, unless
they  shall have offered  to the Trustee security  and indemnity satisfactory to
it.

    The Indenture and the TIA will contain certain limitations on the rights  of
the  Trustee, should it become  a creditor of the  Company, to obtain payment of
claims in certain cases or to realize on certain property received in respect of
any such claim as security or otherwise. Subject to the TIA, the Trustee will be
permitted to  engage  in  other  transactions, provided,  however,  that  if  it
acquires  any conflicting interest (as described  in the TIA), it must eliminate
such conflict or resign.

                   CERTAIN FEDERAL INCOME TAX CONSIDERATIONS

    The  following  is a  general discussion  of  certain United  States federal
income tax considerations relevant to holders  of the Notes. This discussion  is
based  upon the Internal Revenue Code of 1986, as amended (the "Code"), Treasury
Regulations, Internal Revenue Service ("IRS") rulings and judicial decisions now
in effect, all of which are subject to change (possibly with retroactive effect)
or different interpretations. This discussion does not purport to deal with  all
aspects  of  federal  income  taxation  that may  be  relevant  to  a particular
investor's decision to purchase the Notes, and  it is not intended to be  wholly
applicable  to all categories  of investors, some  of which, such  as dealers in
securities, banks, insurance companies, tax-exempt organizations and  non-United
States persons, may be subject to special rules. In addition, this discussion is
limited to persons that purchase the Notes in the offering and hold the Notes as
a "capital asset" within the meaning of Section 1221 of the Code.

    ALL PROSPECTIVE PURCHASERS OF THE NOTES ARE ADVISED TO CONSULT THEIR OWN TAX
ADVISORS REGARDING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES OF THE
PURCHASE, OWNERSHIP AND DISPOSITION OF THE NOTES AND THE COMMON STOCK.

CONVERSION OF NOTES INTO COMMON STOCK

    In  general, no gain or loss will be recognized for income tax purposes on a
conversion of the Notes into shares of Common Stock. However, cash paid in  lieu
of  a fractional share  of Common Stock  will likely result  in taxable gain (or
loss), which will be  capital gain (or  loss) to the extent  that the amount  of
such  cash exceeds (or is exceeded by) the  portion of the adjusted basis of the
Note allocable to such fractional share. The adjusted basis of shares of  Common
Stock  received  on  conversion  will  equal  the  adjusted  basis  of  the Note
converted, reduced by the portion of adjusted basis allocated to any  fractional
share  of Common Stock exchanged for cash.  The holding period of an investor in
the Common Stock received on conversion will include the period during which the
converted Notes were held.

   
    The conversion price  of the Notes  is subject to  adjustment under  certain
circumstances. See "Description of Notes -- Conversion." Section 305 of the Code
and  the Treasury  Regulations issued  thereunder may  treat the  holders of the
Notes as  having received  a constructive  distribution, resulting  in  ordinary
income  (subject  to a  possible  dividends received  deduction  in the  case of
corporate holders) to the extent of  the Company's current earnings and  profits
as of the end of the taxable year to which the constructive distribution relates
and/or  accumulated  earnings and  profits, if  and to  the extent  that certain
adjustments in  the conversion  price that  may occur  in limited  circumstances
(particularly  an adjustment to reflect a  taxable dividend to holders of Common
Stock) increase the  proportionate interest of  a holder of  Notes in the  fully
diluted  Common Stock, whether or not  such holder ever exercises its conversion
privilege. Moreover, if there is not  a full adjustment to the conversion  price
of  the  Notes  to  reflect  a stock  dividend  or  other  event  increasing the
proportionate interest of the holders of outstanding Common Stock in the  assets
or  earnings and profits of the Company, then such increase in the proportionate
interest of the  holders of  the Common  Stock generally  will be  treated as  a
distribution  to such holders, taxable as ordinary income (subject to a possible
dividends received deduction in the case of corporate holders) to the extent  of
the  Company's current earnings and profits as of the end of the taxable year to
which the  constructive distribution  relates  and/or accumulated  earnings  and
profits.
    

MARKET DISCOUNT

    Investors  acquiring Notes pursuant to this  Prospectus should note that the
resale of  those  Notes  may  be  adversely  affected  by  the  market  discount
provisions  of sections 1276 through 1278 of the Code. Under the market discount
rules, if a holder of a Note purchases  it at market discount (i.e., at a  price
below   its   stated   redemption   price   at   maturity)   in   excess   of  a
statutorily-defined DE  MINIMIS amount  and thereafter  recognizes gain  upon  a
disposition or retirement of the Note, then the lesser of the gain recognized or
the  portion of  the market  discount that  accrued on  a ratable  basis (or, if
elected, on  a  constant interest  rate  basis)  generally will  be  treated  as
ordinary income at the time of the disposition. Moreover, any market discount on
a  Note may be taxable to an investor  to the extent of appreciation at the time
of certain otherwise non-taxable transactions (e.g., gifts). Any accrued  market
discount not

                                       33
<PAGE>
previously  taken into income prior  to a conversion of  a Note, however, should
(under Treasury  Regulations not  yet issued)  carry over  to the  Common  Stock
received  on  conversion and  be treated  as ordinary  income upon  a subsequent
disposition of such Common Stock  to the extent of  any gain recognized on  such
disposition.  In  addition, absent  an election  to  include market  discount in
income as it  accrues, a  holder of  a market  discount debt  instrument may  be
required  to  defer a  portion of  any  interest expense  that otherwise  may be
deductible on any indebtedness incurred or maintained to purchase or carry  such
debt  instrument until the holder  disposes of the debt  instrument in a taxable
transaction.

SALE, EXCHANGE OR RETIREMENT OF NOTES

   
    Each holder of Notes  generally will recognize gain  or loss upon the  sale,
exchange, redemption, repurchase, retirement or other disposition of those Notes
measured  by the difference (if any) between (i) the amount of cash and the fair
market value of any property  received (except to the  extent that such cash  or
other property is attributable to the payment of accrued interest not previously
included  in income, which amount  will be taxable as  ordinary income) and (ii)
the holder's adjusted tax  basis in those Notes  (including any market  discount
previously  included in income by the holder).  Each holder of Common Stock into
which the Notes are converted, in general, will recognize gain or loss upon  the
sale,  exchange, redemption, or  other disposition of  the Common Stock measured
under rules similar to those described in the preceding sentence for the  Notes.
Special  rules may  apply to  redemptions of  Common Stock  which may  result in
different treatment. Any  such gain or  loss recognized on  the sale,  exchange,
redemption,  repurchase, retirement or  other disposition of a  Note or share of
Common Stock  should be  capital gain  or loss  (except as  discussed under  "--
Market Discount" above), and would be long-term capital gain or loss if the Note
or the Common Stock had been held for more than one year at the time of the sale
or  exchange. An investor's initial basis in a  Note will be the cash price paid
therefor.
    

BACKUP WITHHOLDING

    A holder of Notes or Common Stock may be subject to "back-up withholding" at
a rate of 31% with respect to certain "reportable payments," including  interest
payments, dividend payments and, under certain circumstances, principal payments
on  the Notes. These back-up withholding rules  apply if the holder, among other
things, (i)  fails  to  furnish  a social  security  number  or  other  taxpayer
identification  number  ("TIN") certified  under penalties  of perjury  within a
reasonable time after  the request  therefor, (ii) furnishes  an incorrect  TIN,
(iii)  fails to  report properly  interest or  dividends, or  (iv) under certain
circumstances, fails to provide a certified statement, signed under penalties of
perjury, that the TIN furnished  is the correct number  and that such holder  is
not  subject to back-up withholding.  A holder who does  not provide the Company
with its correct TIN also  may be subject to penalties  imposed by the IRS.  Any
amount  withheld from a payment to a  holder under the back-up withholding rules
is creditable against the  holder's federal income  tax liability, provided  the
required  information  is furnished  to the  IRS.  Back-up withholding  will not
apply, however,  with respect  to payments  made to  certain holders,  including
corporations,  tax-exempt  organizations and  certain foreign  persons, provided
their exemption from back-up withholding is properly established.

    The Company will report to the holders of Notes and Common Stock and to  the
IRS  the amount  of any  "reportable payments"  for each  calendar year  and the
amount of tax withheld, if any, with respect to such payments.

</TABLE>

    In the Underwriting Agreement, the Underwriters have agreed, subject to  the
terms and conditions set forth therein, that the obligations of the Underwriters
are  subject to certain  conditions precedent and that  the Underwriters will be
obligated to purchase the entire principal amount of the Notes offered hereby if
any Notes are purchased.

    The Company has been advised by the Underwriters that they propose to  offer
the  Notes directly to the public at the initial public offering price set forth
on the cover  of this Prospectus  and to certain  dealers at such  price less  a
concession  of not  more than     %  of the  principal amount of  the Notes. The
Underwriters may allow, and such dealers may reallow, a concession not in excess
of    % of the principal amount of the Notes. After the initial public  offering
of the Notes, the public offering price and such concessions may be changed.

   
    The  Underwriting  Agreement provides  that the  Company will  indemnify the
Underwriters against certain civil liabilities, including liabilities under  the
Securities  Act or contribute to payments  that the Underwriters may be required
to make in respect thereof.
    

   
    The Underwriters will reimburse the Company for certain expenses relating to
the offering.
    

    Except for certain exceptions pertaining to certain employee benefit  plans,
outstanding  options  and  warrants  to  purchase  Common  Stock  and securities
convertible into Common Stock, the Company has agreed that it will not,  without
the prior written consent of Salomon Brothers Inc, for a period of 90 days after
the   date  on  which  the  Underwriting  Agreement  is  executed,  directly  or
indirectly, offer to sell, sell, grant any  option for the sale of or  otherwise
dispose  of any  shares of  Common Stock or  any securities  convertible into or
exchangeable or exercisable  for any  shares of Common  Stock, or  any right  or
option  to acquire any  such shares or  securities. Sales by  the Company to the
Underwriters are exempt from such restriction.

   
    In connection  with the  offering, certain  Underwriters and  selling  group
members  who are  qualifying registered  market makers  on Nasdaq  may engage in
passive market making transactions in the  Common Stock on Nasdaq in  accordance
with  Rule 10b-6A  under the  Exchange Act  during the  two business  day period
before commencement of  offers or sales  of the Notes  in the offering.  Passive
market making transactions must comply with certain volume and price limitations
and  be identified as such.  In general, a passive  market maker may display its
bid at a price not  in excess of the highest  independent bid for the  security,
and  if all independent bids  are lowered below the  passive market maker's bid,
then such bid must be lowered when cetain purchase limits are exceeded.
    

   
    The Company intends to apply for approval for the Notes to be quoted on  the
Nasdaq  Stock Market. However, no assurance can be given that any market for the
Notes will  develop. See  "Risk Factors  --  Absence of  Public Market  for  the
Notes."

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

    The  Company has the power, pursuant to  Section 145 of the Delaware General
Corporation Law, to limit the liability of directors to the Company for  certain
breaches  of fiduciary duty  and to indemnify its  directors, officers and other
persons for certain acts. The  Company's Restated Certificate of  Incorporation,
as amended, includes the following provision:

    "11.   LIMITATION OF DIRECTORS' LIABILITY.   To the fullest extent permitted
    by the Delaware  General Corporation Law  as the  same exists or  as it  may
    hereafter  be amended, a director of the Corporation shall not be personally
    liable to  the Corporation  or  its stockholders  for monetary  damages  for
    breach  of fiduciary duty as a director. Neither any amendment nor repeal of
    this Article 11, nor  the adoption of any  provision of this Certificate  of
    Incorporation  inconsistent with this Article  11, shall eliminate or reduce
    the effect of this  Article 11 in  respect of any  matter occurring, or  any
    cause  of action, suit or claim that,  but for this Article 11, would accrue
    or arise, prior  to such amendment,  repeal or adoption  of an  inconsistent
    provision."

    Article  VI of  the Bylaws  of the Company  provides that  the Company shall
indemnify certain agents  of the Company  against judgments, fines,  settlements
and  other  expenses arising  from such  person's  agency relationship  with the
Company provided that  the standard  of conduct set  forth therein  is met.  The
effect  of Article VI is to require  that the Company provide indemnification to
such agents to the maximum extent permitted by the Delaware General  Corporation
Law. Agents covered by this indemnification provision include current and former
directors  and officers  of the  Company, as  well as  persons who  serve at the
request of the Company  as directors, officers, employees  or agents of  another
enterprise.

    In  addition, the Company  has entered into  indemnification agreements with
each  of  its  directors  and  certain  of  its  officers.  The  indemnification
agreements  are based on the  provisions of Section 145  of the Delaware General
Corporation Law and attempt to provide the directors and officers of the Company
with  the  maximum  indemnification  allowed  under  Delaware  law.  In  certain
instances,  they  may  result  in an  expansion  of  the  substantive protection
available to such  individuals under the  Restated Certificate of  Incorporation
and the Bylaws.

    The   Company  currently   maintains  directors'   and  officers'  liability
insurance, but  the policy  does not  provide coverage  for liabilities  arising
under the Securities Act.

    Reference  is also made to Section 8 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 of 1933, each filing of  the
Registrant's  annual report  pursuant to Section  13(a) or Section  15(d) of the
Securities Exchange  Act  of 1934  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
of 1933 may be permitted to  directors, officers and controlling persons of  the
Registrant  pursuant to provisions described in Item 15 hereof 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 of  1933 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 of whether
such  indemnification  by  it  is  against public  policy  as  expressed  in the
Securities Act of 1933 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
    of 1933, the information omitted from  the form of Prospectus filed as  part
    of this Registration Statement in reliance upon

                                      II-2
<PAGE>
    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 of 1933
    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  of  1933,  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 of such securities at  that
    time shall be deemed to be the initial bona fide offering thereof.

                                   SIGNATURES

   
    Pursuant  to the requirements of the Securities Act of 1933, the Registrant,

Ladies and Gentlemen:

    VLSI  Technology, Inc., a Delaware  corporation (the "Company"), proposes to
sell to  the  underwriters named  in  Schedule I  hereto  (the  "Underwriters"),
$150,000,000  principal amount of  its     % Convertible  Subordinated Notes Due
2005  (the  "Convertible  Notes"),  to   be  issued  under  an  indenture   (the
"Indenture")  to be dated as of           , 1995, between the Company and Harris
Trust and Savings Bank,  as trustee (the "Trustee").  The Securities (as  herein
defined)  are convertible into  shares of Common  Stock, $.01 par  value, of the
Company ("Common Stock"). The Company also proposes to grant to the Underwriters
an option to purchase up to an additional $22,500,000 aggregate principal amount
of Convertible  Notes (the  "Option Notes,"  and together  with the  Convertible
Notes,  the  "Securities"). Terms  not otherwise  defined  herein have  the same
meanings as set forth in the Indenture.

    1.  REPRESENTATIONS AND WARRANTIES.  The Company represents and warrants to,
and agrees with, each Underwriter as set forth below in this Section 1.  Certain
terms used in this Section 1 are defined in paragraph (c) hereof.

        (a)  The Company meets  the requirements for  use of Form  S-3 under the
    Securities Act of  1933 (the "Act")  and has filed  with the Securities  and
    Exchange Commission (the "Commission") a registration statement (file number
    33-62161)  on such Form, including a related preliminary prospectus, for the
    registration under the Act of the  offering and sale of the Securities.  The
    Company may have filed one or more amendments thereto, including the related
    preliminary  prospectus, each of which has previously been furnished to you.
    The Company will  next file with  the Commission one  of the following:  (i)
    prior  to effectiveness of such  registration statement, a further amendment
    to such registration statement, including the form of final prospectus, (ii)
    a final prospectus in  accordance with Rules 430A  and 424(b)(1) or (4),  or
    (iii)  a final prospectus in accordance with Rules 415 and 424(b)(2) or (5).
    In the case of  clause (ii), the Company  has included in such  registration
    statement,  as amended  at the Effective  Date, all  information (other than
    Rule 430A Information) required  by the Act and  the rules thereunder to  be
    included  in the Prospectus with respect  to the Securities and the offering
    thereof. As filed,  such amendment  and form  of final  prospectus, or  such
    final prospectus, shall contain all Rule 430A Information, together with all
    other  such required  information, with  respect to  the Securities  and the
    offering thereof and, except to the  extent the Underwriters shall agree  in
    writing  to a modification, shall be in all substantive respects in the form
    furnished to you prior to the Execution Time or, to the extent not completed
    at the Execution Time,
<PAGE>
    shall contain only  such specific additional  information and other  changes
    (beyond  that contained in the latest Preliminary Prospectus) as the Company
    has advised  you, prior  to the  Execution Time,  will be  included or  made
    therein. Upon the effectiveness of the Registration Statement, the Indenture
    will  be qualified under  the Trust Indenture  Act of 1939,  as amended (the
    "Trust Indenture Act"), and the respective rules thereunder.

        (b) On the Effective Date, the  Registration Statement did or will,  and
    when  the Prospectus  is first filed  (if required) in  accordance with Rule
    424(b) and on the Closing Date, the Prospectus (and any supplements thereto)
    will, comply in all  material respects with  the applicable requirements  of
    the  Act, the Securities Exchange  Act of 1934 (the  "Exchange Act") and the
    Trust Indenture Act and  the respective rules  thereunder; on the  Effective
    Date,  the Registration  Statement did  not or  will not  contain any untrue
    statement of a material fact or omit to state any material fact required  to
    be  stated therein or necessary in order  to make the statements therein not
    misleading; on the Effective Date and on the Closing Date the Indenture  did
    or  will comply in all material respects with the applicable requirements of
    the Trust Indenture  Act and  the rules  thereunder; and,  on the  Effective
    Date,  the Prospectus, if not filed pursuant to Rule 424(b), did not or will
    not, and  on the  date of  any filing  pursuant to  Rule 424(b)  and on  the
    Closing  Date, the  Prospectus (together  with any  supplement thereto) will
    not, include 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;
    PROVIDED,  HOWEVER, that the Company  makes no representations or warranties

    Statement  of  Eligibility  and  Qualification (Form  T-1)  under  the Trust
    Indenture Act of the Trustee or (ii) the information contained in or omitted

        (d) The documents incorporated by reference in the Prospectus, when they
    became effective or  were filed  with the Commission,  as the  case may  be,
    complied  in all material respects with the requirements of the Exchange Act
    and the rules  thereunder, and none  of such documents  contained an  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, in the light
    of the circumstances  under which  they were  made, not  misleading and  any
    further  documents so filed and incorporated  by reference in the Prospectus

    Underwriter specifically for inclusion in such documents.

        (e) No  order  preventing  or  suspending the  use  of  any  Preliminary
    Prospectus   has  been  issued  by  the  Commission,  and  each  Preliminary
    Prospectus, at the time of filing thereof, complied in all material respects
    with the requirements  of the Act  and the Exchange  Act and the  respective
    rules  thereunder, and  did not contain  any untrue statement  of a material
    fact or omit  to state  a material  fact required  to be  stated therein  or
    necessary  to make the statements therein, in the light of the circumstances
    under which  they were  made, not  misleading; PROVIDED,  HOWEVER, that  the
    Company  makes  no  representations  or  warranties  as  to  the information
    contained therein  or  omitted  therefrom  made  in  reliance  upon  and  in
    conformity  with information  furnished in writing  to the Company  by or on
    behalf of any Underwriter specifically for inclusion therein.

        (f)  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 in which it is chartered or organized, with full corporate
    power and  authority to  own  its properties  and  conduct its  business  as
    described  in the  Prospectus, and  is duly  qualified to  do business  as a
    foreign corporation  and  is  in  good  standing  under  the  laws  of  each
    jurisdiction  that  requires such  qualification wherein  it owns  or leases
    material properties or conducts material business, except for those failures
    to be so qualified or in good standing that will not in the aggregate have a
    material adverse effect on the Company and its subsidiaries considered as  a
    whole.

        (g)  All the outstanding shares of capital stock of each subsidiary have
    been duly  and  validly  authorized  and  issued  and  are  fully  paid  and
    nonassessable,  and, except  as otherwise set  forth in  the Prospectus, all
    outstanding shares of  capital stock of  the subsidiaries are  owned by  the
    Company  either directly  or through  wholly owned  subsidiaries (except for
    directors' qualifying shares or shares held  by nominees as required by  the
    laws  of certain  non-United States jurisdictions  and except  for shares of
    common  stock  of  COMPASS  Design  Automation,  Inc.  ("COMPASS")  held  by
    employees  or former employees of the Company  or COMPASS) free and clear of
    any perfected security  interest and any  other security interests,  claims,
    liens or encumbrances.

                                       3

        (h) The Company's authorized, issued and outstanding capital stock is as
    set  forth in the Prospectus;  the capital stock of  the Company conforms to
    the  description  thereof  contained  in  the  Registration  Statement;  the
    outstanding  shares of capital stock of the Company and options and warrants
    to purchase  capital  stock  of  the Company  have  been  duly  and  validly
    authorized  and issued  and the outstanding  shares of capital  stock of the
    Company are fully  paid and  nonassessable; and the  holders of  outstanding
    shares  of capital stock  of the Company  are not entitled  to preemptive or
    other similar rights to subscribe for the Securities.

        (i)  The consolidated financial statements of the Company, together with
    the notes thereto,  included in  the Registration  Statement and  Prospectus
    comply  in all material respects with the requirements of the Act and fairly
    present the financial condition of the Company as of the dates indicated and
    the results of operations and changes in cash flows for the periods  therein
    specified  in  conformity  with  generally  accepted  accounting  principles
    consistently applied throughout  the periods involved  (except as  otherwise
    stated  therein); and the supporting  schedules included in the Registration
    Statement present fairly the information  required to be stated therein.  No
    other  financial statements or schedules are  required to be included in the
    Registration Statement or Prospectus. Ernst & Young LLP, which has expressed
    its opinion with respect to the financial statements and schedules filed  as
    a  part  of  the Registration  Statement  and included  in  the Registration
    Statement and Prospectus, are independent public accountants as required  by
    the Act and the rules thereunder. The financial information appearing in the
    Prospectus  under the  captions "Prospectus Summary  -- Summary Consolidated
    Financial Data," "Capitalization" and "Selected Consolidated Financial Data"
    are fairly stated  in all  material respects  as of  the dates  and for  the
    periods indicated.

        (j)    No  holders  of  securities  of  the  Company  other  than  Intel
    Corporation have rights  to the  registration of such  securities under  the
    Registration  Statement. Except  as disclosed in  the Registration Statement
    and the Prospectus, there are no options, warrants, agreements, contracts or
    other rights in existence  to purchase or acquire  from the Company, or  any

    deliver  and perform its obligations under this Agreement, the Indenture and
    the  Securities  and  to  execute   and  deliver  all  other  documents   or
    certificates required or contemplated hereby or thereby. The Securities have
    been  duly authorized by the Company for  issuance and sale pursuant to this
    Agreement, and, when  issued, authenticated and  delivered pursuant to  this
    Agreement  and the Indenture against payment  of the consideration set forth
    herein, will constitute valid and legally binding obligations of the Company
    enforceable  in   accordance  with   their  terms,   except  (i)   as   such
    enforceability  may  be limited  by bankruptcy,  insolvency, reorganization,
    moratorium or other similar laws now  or hereafter in effect relating to  or
    affecting  enforcement  of creditors'  rights  generally and  (ii)  that the
    remedy of specific performance and  injunctive and other forms of  equitable
    relief  may be subject  to equitable defenses  and to the  discretion of the
    court  before  which  any  proceeding  therefor  may  be  brought;  and  the
    Securities  would be entitled to the benefits provided by the Indenture; the
    Indenture has been duly  authorized and, on the  Closing Date, will be  duly
    qualified  under the  Trust Indenture  Act and,  assuming due  execution and
    delivery by the  Trustee, when executed  and delivered by  the Company  will
    constitute   a  valid  and  legally   binding  obligation  of  the  Company,
    enforceable in accordance with its terms, except (i) as enforcement  thereof
    may  be  limited by  bankruptcy,  insolvency, reorganization,  moratorium or
    other similar  laws now  or hereafter  in effect  relating to  or  affecting
    enforcement  of  creditors' rights  generally and  (ii)  that the  remedy of
    specific performance and injunctive and other forms of equitable relief  may
    be  subject to equitable defenses and to  the discretion of the court before
    which any  proceeding  therefor  may  be brought;  the  Securities  and  the

                                       4

    Indenture  conform in all  material respects to  the descriptions thereof in
    the Prospectus; the Indenture complies as  to form in all material  respects

    thereunder.

        (m) The Securities are convertible into  Common Stock of the Company  in
    accordance  with  the terms  of the  Indenture. The  shares of  Common Stock
    initially  issuable  upon  conversion  of  the  Securities  have  been  duly
    authorized  and reserved  for issuance  and, when  the certificates therefor
    have been duly countersigned by  the Company's transfer agent and  delivered
    upon such conversion in accordance with the provisions of the Securities and
    the  Indenture, will be  validly issued, fully  paid and nonassessable, will
    not have been issued in violation of or subject to any preemptive or similar
    rights and will conform to the description of the Common Stock contained  in
    the Prospectus.

        (n)  The issue and  sale of the Securities,  the execution, delivery and
    performance  of  the  Indenture,  the  consummation  of  any  other  of  the
    transactions  herein  or therein  contemplated, and  the fulfillment  of the
    terms hereof  and thereof  will not  conflict with,  result in  a breach  or
    violation  of, or constitute a  default under (i) any  law (other than state
    blue sky laws, as to which the Company makes no representation) or (ii)  the
    charter  or by-laws of  the Company or  (iii) the terms  of any indenture or
    other material agreement or  instrument to which the  Company or any of  its
    subsidiaries  is a  party or  bound or  (iv) any  judgment, order  or decree
    applicable to  the  Company  or  any  of  its  subsidiaries  of  any  court,

    party  (whether acting in an individual, fiduciary or other capacity) or any
    court or governmental agency or body is  required for the issue and sale  of
    the Securities, the execution, delivery and performance of the Indenture, or
    the consummation of the transactions contemplated herein and therein, except
    (i)  such as have been obtained under the  Act, (ii) such as may be required
    under the blue sky laws of any jurisdiction in connection with the  purchase
    and   distribution  of  the  Securities   by  the  Underwriters,  (iii)  the
    qualification of the Indenture under the  Trust Indenture Act and (iv)  such
    other approvals as have been obtained.

        (p)  There is no pending or threatened action, suit or proceeding before
    any court  or  governmental agency,  authority  or body  or  any  arbitrator
    involving  the Company or any of its subsidiaries of a character required to
    be disclosed in the Registration Statement that is not adequately  disclosed
    in  the Prospectus, and there is no franchise, contract or other document of
    a character  required  to be  described  in the  Registration  Statement  or
    Prospectus,  or to be filed as an exhibit, that is not described or filed as
    required; and  the statements  in the  Prospectus under  the headings  "Risk
    Factors  -- TI Litigation;  Intellectual Property Matters"  and "Business --
    Litigation" fairly summarize the matters therein described.

    subsidiaries  holds, and is operating in compliance in all material respects
    with,  all  franchises,   grants,  authorizations,   licenses  (other   than

    with all applicable  federal, state,  local and  foreign laws,  regulations,

    subsidiaries  has transported, stored or  disposed of any hazardous material
    or substance in  a manner  that would give  rise to  any material  liability
    under  current law, and neither the Company  nor any of its subsidiaries has
    received any  inquiries from  any  governmental or  regulatory body  or  any
    claims  in any way relating to any  such liability for disposal of hazardous
    materials or substances.

        (r) Neither the Company nor any  of its subsidiaries is in violation  of
    its  respective charter or  bylaws or in  breach of or  otherwise in default

    of  any material obligation,  agreement or condition  contained in any bond,
    debenture, note, indenture, loan agreement  or any other material  contract,
    lease  or other  instrument to  which it is  subject or  by which  it may be
    bound, or to which any of the material property or assets of the Company  or
    any of its subsidiaries is subject, except for such breaches of contracts as
    would  not result  in a material  adverse effect on  the Company's business,

    such as do  not materially  affect the  value of  such property  and do  not
    interfere  with the use made and proposed to be made of such property by the
    Company and its  subsidiaries; any  real property and  buildings held  under
    lease  by the Company  and its subsidiaries and  any other material property
    held under lease by the Company and its subsidiaries are held by them  under
    valid,  subsisting  and enforceable  leases with  only such  exceptions with
    respect to any  particular lease as  are not material  and do not  interfere
    with  the use made and  proposed to be made of  such property by the Company
    and its subsidiaries.

    and/or  unpatentable  proprietary  or confidential  information,  systems or
    procedures) and  rights  necessary  for  the  conduct  of  its  business  as
    currently  carried on; except  as disclosed in the  Prospectus, no name that
    the Company or  any of  its subsidiaries  uses and  no other  aspect of  the
    business of the Company or any of its subsidiaries will involve or give rise
    to  any infringement of, or license or similar fees for, in either case that
    would have a material  adverse effect on the  Company and its  subsidiaries,
    considered as a whole, any patents, patent applications, trademarks, service
    marks,  tradenames,  trademark  registrations,  service  mark registrations,

    4.     OFFERING  BY  UNDERWRITERS.    It  is  understood  that  the  several
Underwriters propose to offer the Securities for sale to the public as set forth
in the Prospectus.

    5.  AGREEMENTS.  The Company agrees with the several Underwriters that:

        (a) The Company  will use  its best  efforts to  cause the  Registration
    Statement,  if  not  effective  at the  Execution  Time,  and  any amendment
    thereof, to become effective.  Prior to the termination  of the offering  of
    the  Securities, the Company will not file any amendment of the Registration
    Statement or supplement to the  Prospectus unless the Company has  furnished
    you  a copy  for your  review prior  to filing  and will  not file  any such
    proposed amendment or supplement to which you reasonably object. Subject  to
    the  foregoing sentence, if the Registration Statement has become or becomes
    effective pursuant to Rule  430A, or filing of  the Prospectus is  otherwise
    required  under Rule 424(b), the Company will cause the Prospectus, properly
    completed, and  any  supplement thereto  to  be filed  with  the  Commission
    pursuant  to the applicable paragraph of  Rule 424(b) within the time period
    prescribed and will  provide evidence  satisfactory to  the Underwriters  of
    such  timely filing. The  Company will promptly  advise the Underwriters (i)
    when the Registration Statement, if not effective at the Execution Time, and
    any  amendment  thereto,  shall  have   become  effective,  (ii)  when   the
    Prospectus,  and any supplement thereto, shall have been filed (if required)
    with  the  Commission  pursuant  to  Rule  424(b),  (iii)  when,  prior   to
    termination  of  the  offering  of  the  Securities,  any  amendment  to the
    Registration Statement shall have  been filed or  become effective, (iv)  of
    any  request  by  the  Commission  for  any  amendment  of  the Registration
    Statement or supplement to the Prospectus or for any additional information,
    (v) of  the issuance  by the  Commission of  any stop  order suspending  the
    effectiveness   of  the   Registration  Statement  or   the  institution  or
    threatening of any proceeding  for that purpose and  (vi) of the receipt  by
    the  Company  of any  notification  with respect  to  the suspension  of the
    qualification of  the  Securities  for  sale  in  any  jurisdiction  or  the
    initiation  or threatening of  any proceeding for  such purpose. The Company
    will use its best  efforts to prevent  the issuance of  any such stop  order
    and, if issued, to obtain as soon as possible the withdrawal thereof.

        (b)  If, at  any time  when a prospectus  relating to  the Securities is
    required to be  delivered under the  Act, any  event occurs as  a result  of
    which the Prospectus as then supplemented would include any untrue statement
    of  a material fact or omit to state any material fact necessary to make the
    statements therein in the light of  the circumstances under which they  were
    made  not misleading, or if it shall  be necessary to amend the Registration
    Statement or supplement the Prospectus to comply with the Act, the  Exchange
    Act  or  the  Trust  Indenture  Act  or  the  respective  rules  thereunder,

                                       8
<PAGE>
    the Company promptly will prepare and  file with the Commission, subject  to
    the  second sentence  of paragraph  (a) of this  Section 5,  an amendment or
    supplement  that  corrects  such  statement  or  omission  or  effects  such
    compliance.

        (c) As soon as practicable, the Company will make generally available to
    its  security  holders  and to  the  Underwriters an  earnings  statement or
    statements of  the  Company  and  its subsidiaries  that  will  satisfy  the
    provisions of Section 11(a) of the Act and Rule 158 under the Act.

        (d)  The Company will  furnish to counsel  for the Underwriters, without
    charge, a  signed copy  of the  Registration Statement  (including  exhibits
    thereto)  and  to  each Underwriter  a  copy of  the  Registration Statement
    (including exhibits thereto) and, so long as delivery of a prospectus by  an
    Underwriter  or dealer may  be required by  the Act, as  many copies of each
    Preliminary Prospectus and the Prospectus and any supplement thereto as  the
    Underwriters  may reasonably request.  The Company will  pay the expenses of
    printing or other production of all documents relating to the offering.

        (e) The Company will arrange for the qualification of the Securities for
    sale under the laws of such jurisdictions as the Underwriters may designate,
    will maintain such  qualifications in  effect so  long as  required for  the
    distribution  of  the  Securities  and  will pay  the  fee  of  the National
    Association of Securities Dealers,  Inc., in connection  with its review  of
    the offering.

        (f)   The Company waives, to the extent permitted by law, the use of any
    usury laws against any holder of Securities.

        (g) The Company will reserve, from time to time, a sufficient number  of
    shares of Common Stock to permit the issuance of shares of Common Stock upon
    the conversion of all of the outstanding Securities by the holders thereof.

        (h)  The Company will cause the  Securities to be included for quotation
    on the Nasdaq  Stock Market  within a reasonable  amount of  time after  the
    Closing Date.

        (i)   The  Company agrees  to notify the  Nasdaq National  Market of the
    shares of Common Stock issuable upon conversion of the Securities and to pay
    the fees required by Schedule D to the NASD By-Laws in connection therewith.

        (j)   The Company  will  not, for  a period  of  90 days  following  the
    Execution  Time, without the prior written  consent of Salomon Brothers Inc,
    offer, sell  or contract  to  sell, or  otherwise  dispose of,  directly  or
    indirectly, or announce the offering of, any other shares of Common Stock or
    any other securities convertible into, or exchangeable for, shares of Common
    Stock;  PROVIDED, HOWEVER, that the Company  may issue and sell Common Stock
    pursuant to any employee  or director stock option  or purchase plan of  the
    Company  in effect at the Execution Time, the Company may issue Common Stock
    as consideration in an acquisition of the stock or assets of another entity,
    and the  Company may  issue Common  Stock issuable  upon the  conversion  of
    securities or the exercise of warrants outstanding at the Execution Time.

        (k)  The  Company  will inform  the  Florida Department  of  Banking and
    Finance at any  time prior to  the consummation of  the distribution of  the
    Securities by the Underwriters if it commences engaging in business with the
    government  of Cuba or  with any person  or affiliate located  in Cuba. Such
    information will be provided within  90 days after the commencement  thereof
    or after a change occurs with respect to previously reported information.

the several Underwriters to purchase the Convertible Notes and the Option Notes,

    price, if such determination occurred at or  prior to 3:00 PM New York  City
    time  on such date or (ii) 12:00 Noon  on the business day following the day
    on which the  public offering  price was determined,  if such  determination
    occurred  after 3:00 PM  New York City time  on such date;  if filing of the
    Prospectus, or any supplement thereto, is required pursuant to Rule  424(b),
    the  Prospectus, and any  such supplement, will  be filed in  the manner and
    within the time period required by Rule 424(b); and no stop order suspending
    the effectiveness of the Registration  Statement shall have been issued  and
    no proceedings for that purpose shall have been instituted or threatened.

        (b)  The Company shall have furnished to the Underwriters the opinion of
    Wilson, Sonsini, Goodrich  & Rosati, Professional  Corporation, counsel  for
    the Company, dated the Closing Date, to the effect that:

            (i)  each of the Company and  COMPASS has been duly incorporated and
       is validly existing as a corporation  in good standing under the laws  of
       the  jurisdiction  in  which  it is  chartered  or  organized,  with full
       corporate power  and authority  to  own its  properties and  conduct  its
       business as described in the Prospectus;

           (ii)  the Company's authorized  capital stock is as  set forth in the
       Prospectus; the capital stock of the Company conforms to the  description
       thereof  contained  or  incorporated  by  reference  in  the Registration
       Statement; and the certificates for the Securities are in the form called
       for by the Indenture;

           (iii) this Agreement has been duly authorized, executed and delivered
       by the Company;

           (iv) the Indenture has been  duly authorized, executed and  delivered
       by  the Company, has  been duly qualified under  the Trust Indenture Act,
       and constitutes a  valid and binding  instrument enforceable against  the
       Company  in  accordance with  its terms;  the  Securities have  been duly
       authorized and, when  executed and authenticated  in accordance with  the
       provisions  of  the  Indenture  and  delivered to  and  paid  for  by the
       Underwriters pursuant  to  this  Agreement,  will  constitute  valid  and
       binding  obligations  of  the Company  entitled  to the  benefits  of the
       Indenture; the Indenture  complies as  to form in  all material  respects
       with   the  requirements  of  the  Trust  Indenture  Act  and  the  rules
       thereunder; the  Indenture and  the Securities  conform in  all  material
       respects  to the descriptions  thereof contained in  the Prospectus under
       "Description of Notes";

           (v) the shares of Common Stock  initially issuable as of the  Closing
       Date  upon conversion  of the  Securities have  been duly  authorized and
       reserved for  issuance upon  such conversion  and, if  issued as  of  the
       Closing  Date  upon  conversion  in  accordance  with  the  terms  of the
       Securities  and   the  Indenture   (without  regard   to  the   lack   of
       convertibility  as of such date), (a) would be validly issued, fully paid
       and nonassessable and (b) would conform to the description of the  Common
       Stock contained in the Prospectus;

           (vi) neither the issue and sale of the Securities, nor the execution,
       delivery  and  performance  of  the Indenture  by  the  Company,  nor the
       consummation of any other of the transactions herein contemplated nor the
       fulfillment of the terms hereof will conflict with, result in a breach or
       violation of, or constitute a default under (A) the charter or by-laws of
       the Company or (B) the terms of the Intel/VLSI Stock and Warrant Purchase
       Agreement dated July 8, 1992, the  Warrant dated August 25, 1992,  issued
       to  Intel Corporation, [or the Credit Agreement  dated as of June 6, 1994
       among the Company, the lenders  named therein and Continental Bank  N.A.,
       as  agent (the  "Credit Agreement"), or  the Loan  and Security Agreement
       dated  as  of  December  15,  1993  between  the  Company  and  the   CIT
       Group/Equipment  Financing, Inc.,] or (C) any material judgment, order or
       decree known to such counsel to  be applicable to the Company or  COMPASS
       of  any court, regulatory body,  administrative agency, governmental body
       or arbitrator having jurisdiction over the Company or COMPASS;

                                       10
<PAGE>
          (vii) no consent, approval, authorization or order of any third  party
       (whether  acting in an individual, fiduciary or other capacity) or of any
       court or governmental agency or body  is required for the issue and  sale
       of  the  Securities,  the  execution,  delivery  and  performance  of the
       Indenture or the  consummation of the  transactions contemplated  herein,
       except  such  as have  been obtained  under the  Act and  such as  may be
       required under the blue sky laws  of any jurisdiction in connection  with
       the  purchase  and  distribution  of  the  Securities  by  the Underwrit-
       ers and such  other approvals (specified  in such opinion)  as have  been
       obtained;

          (viii) the Company is not, and upon receipt and pending application of
       the  net  proceeds  from the  sale  of  the Common  Stock  in  the manner
       described in the Prospectus will  not be, an "investment company"  within
       the meaning of the Investment Company Act of 1940, as amended;

           (ix) the documents incorporated by reference in the Prospectus or any
       further amendment or supplement thereto made by the Company prior to such
       Closing  Date (other than the  financial statements and related schedules
       and other financial and statistical information contained therein, as  to
       which  such counsel need express no  opinion), when they became effective
       or were  filed with  the Commission,  as  the case  may be  (unless  such
       documents  have thereafter been amended, in  which case when so amended),
       complied as to form in all material respects with the requirements of the
       Exchange Act and the rules thereunder; and such counsel has no reason  to
       believe  that any such documents, when such documents became effective or
       were so filed,  as the  case may  be (or  if amended,  when so  amended),
       contained,  in the case  of documents that were  filed under the Exchange
       Act with  the Commission,  an  untrue statement  of  a material  fact  or
       omitted  to  state  a  material  fact  necessary  in  order  to  make the
       statements therein, in the  light of the  circumstances under which  they
       were  made when  such documents  were so  filed (or  if amended,  when so
       amended), not misleading; and

           (x) the Registration  Statement has become  effective under the  Act;
       any  required  filing of  the  Prospectus, and  any  supplements thereto,
       pursuant to Rule 424(b) has been made  in the manner and within the  time
       period required by Rule 424(b); to the best knowledge of such counsel, no
       stop order suspending the effectiveness of the Registration Statement has
       been  issued, no  proceedings for  that purpose  have been  instituted or
       threatened; and the Registration Statement and the Prospectus (other than
       the financial statements  and related schedules  and other financial  and
       statistical  information contained therein, as to which such counsel need
       express no opinion) comply as to  form in all material respects with  the
       applicable  requirements  of the  Act, the  Exchange  Act, and  the Trust
       Indenture Act and the respective rules thereunder.

            In addition,  such counsel  shall  state that  such counsel  has  no
    reason  to believe  that at  the Effective  Date the  Registration Statement
    contained any untrue statement  of a material fact  or omitted to state  any
    material  fact  required  to be  stated  therein  or necessary  to  make the
    statements therein not misleading or that the Prospectus, as of its date and
    as of  the Closing  Date, included  or includes  any untrue  statement of  a
    material fact or omitted or omits to state a material fact necessary to make
    the  statements therein, in the light  of the circumstances under which they
    were made, not misleading.

        (c) The Company shall have furnished to the Underwriters the opinion  of
    Thomas C. Tokos, Assistant General Counsel of the Company, dated the Closing
    Date, to the effect that:

            (i)  each of the Company, COMPASS and VLSI Tech. Gmbh ("VLSI Tech.")
       has been duly incorporated  and is validly existing  as a corporation  in
       good standing under the laws of the jurisdiction in which it is chartered
       or  organized,  with  full  corporate  power  and  authority  to  own its
       properties and conduct its business  as described in the Prospectus,  and
       is  duly qualified to do business as a foreign corporation and is in good
       standing  under  the  laws  of  each  jurisdiction  that  requires   such
       qualification  wherein it owns or  leases material properties or conducts
       material business, except for those failures to be so qualified that will
       not in the aggregate  have a material adverse  effect on the Company  and
       its subsidiaries considered as a whole;

                                       11
<PAGE>
           (ii)  all the outstanding shares of capital stock of COMPASS and VLSI
       Tech. have been duly and validly authorized and issued and are fully paid
       and nonassessable, and, except as otherwise set forth in the  Prospectus,
       all  outstanding shares  of capital stock  of COMPASS and  VLSI Tech. are
       owned by the Company either directly or through wholly owned subsidiaries
       (except for directors' qualifying  shares or shares  held by nominees  as
       required  by  the laws  of  certain non-United  States  jurisdictions and
       except for shares of common stock of COMPASS held by employees or  former
       employees  of the  Company or  COMPASS) free  and clear  of any perfected
       security interest  and,  to the  knowledge  of such  counsel,  after  due
       inquiry, any other security interests, claims, liens or encumbrances;

           (iii)  the Company's authorized capital stock  is as set forth in the
       Prospectus; the capital stock of the Company conforms to the  description
       thereof  contained in the Registration  Statement; the outstanding shares
       of capital stock  of the  Company and  options and  warrants to  purchase
       capital  stock of the  Company have been duly  and validly authorized and
       issued and the  outstanding shares of  capital stock of  the Company  are
       fully  paid and nonassessable; the certificates for the Securities are in
       the form called  for by  the Indenture;  and the  holders of  outstanding
       shares  of capital stock of the Company are not entitled to preemptive or
       other rights to subscribe for the Securities or the Common Stock issuable
       upon conversion of the Securities;

           (iv) to  the  knowledge of  such  counsel,  there is  no  pending  or
       threatened  in writing  action, suit  or proceeding  before any  court or
       governmental agency, authority  or body or  any arbitrator involving  the
       Company  or  any  of  its  subsidiaries of  a  character  required  to be
       disclosed in the Registration Statement that is not adequately  disclosed
       in  the Prospectus, and there is no franchise, contract or other document
       of a character required to be described in the Registration Statement  or
       Prospectus,  or to be filed as an exhibit, that is not described or filed
       as required;  and the  statements in  the Prospectus  under the  headings
       "Risk  Factors  --  TI  Litigation;  Intellectual  Property  Matters" and
       "Business -- Litigation" fairly summarize the matters therein described;

           (v) this Agreement has been  duly authorized, executed and  delivered
       by the Company;

           (vi) neither the issue and sale of the Securities, nor the execution,
       delivery  and  performance  of  the Indenture  by  the  Company,  nor the
       consummation of any  other of the  transactions herein contemplated,  nor
       the  fulfillment  of the  terms hereof  will conflict  with, result  in a
       breach or violation of, or constitute  a default under (A) any law  known
       to such counsel (other than state blue sky laws, as to which such counsel
       need  not express an opinion) or (B) the respective charter or by-laws of
       the Company  or  COMPASS or  (C)  the terms  of  any indenture  or  other
       material  agreement or instrument known to  such counsel and to which the
       Company or  any of  its  subsidiaries is  a party  or  bound or  (D)  any
       material judgment, order or decree known to such counsel to be applicable
       to  the Company or any of its subsidiaries of any court, regulatory body,
       administrative   agency,   governmental   body   or   arbitrator   having
       jurisdiction over the Company or any of its subsidiaries;

          (vii)  no  holders  of  securities of  the  Company  other  than Intel
       Corporation have rights to the registration of such securities under  the
       Registration Statement; and

          (viii)  the Registration Statement has become effective under the Act;
       any required  filing  of the  Prospectus,  and any  supplements  thereto,
       pursuant  to Rule 424(b) has been made  in the manner and within the time
       period required  by  Rule 424(b);  and  to  the best  knowledge  of  such
       counsel,  no stop order suspending  the effectiveness of the Registration
       Statement has been issued, and no proceedings for that purpose have  been
       instituted or threatened.

                                       12
<PAGE>
            In  addition,  such counsel  shall state  that  such counsel  has no
    reason to  believe that  at the  Effective Date  the Registration  Statement
    contained  any untrue statement of  a material fact or  omitted to state any
    material fact  required  to be  stated  therein  or necessary  to  make  the
    statements therein not misleading or that the Prospectus, as of its date and
    as  of the  Closing Date,  included or  includes any  untrue statement  of a
    material fact or omitted or omits to state a material fact necessary to make
    the statements therein, in the light  of the circumstances under which  they
    were made, not misleading.

            In  rendering the opinions required by  (b) or (c), such counsel may
    rely (A) as to matters involving the application of laws of any jurisdiction
    other than the  State of  California, the State  of Delaware  or the  United
    States,  to the extent they deem proper  and specified in such opinion, upon
    the opinion  of other  counsel of  good  standing whom  they believe  to  be
    reliable and who are satisfactory to counsel for the Underwriters and (B) as
    to  matters of  fact, to  the extent  they deem  proper, on  certificates of
    responsible officers of the Company and public officials. References to  the
    Prospectus  in paragraphs (b) and (c) include any supplements thereto at the
    Closing Date.

        (d) The Underwriters shall have received from Latham & Watkins,  counsel
    for the Underwriters, such opinion or opinions, dated the Closing Date, with
    respect  to  the issuance  and sale  of the  Securities, the  Indenture, the
    Registration  Statement,  the  Prospectus  (together  with  any   supplement
    thereto)  and other  related matters  as the  Representatives may reasonably
    require, and the Company shall have furnished to such counsel such documents
    as they request for the purpose of enabling them to pass upon such matters.

        (e) The Company shall have  furnished to the Underwriters a  certificate
    of  the Company,  signed by  the Chief  Executive Officer  and the principal
    financial or accounting officer of the  Company, dated the Closing Date,  to
    the  effect that the signers of such certificate have carefully examined the
    Registration Statement, the Prospectus, any supplement to the Prospectus and
    this Agreement and that:

            (i) the  representations  and  warranties of  the  Company  in  this
       Agreement  are true and correct in all material respects on and as of the
       Closing Date with the same effect as if made on the Closing Date and  the
       Company  has  complied  with all  the  agreements and  satisfied  all the
       conditions on its part to  be performed or satisfied  at or prior to  the
       Closing Date;

           (ii)  no stop order suspending  the effectiveness of the Registration
       Statement has been issued and no  proceedings for that purpose have  been
       instituted or, to the Company's knowledge, threatened; and

           (iii) since the date of the most recent financial statements included
       in  the Prospectus (exclusive of any  supplement thereto), there has been
       no material  adverse  change  in  the  condition  (financial  or  other),
       earnings,  business or  properties of  the Company  and its subsidiaries,
       whether or  not  arising from  transactions  in the  ordinary  course  of
       business,  except  as  set forth  in  or contemplated  in  the Prospectus
       (exclusive of any supplement thereto).

        (f)  At the Execution  Time and at the Closing  Date, Ernst & Young  LLP
    shall  have  furnished  to  the  Underwriters  a  letter  or  letters, dated
    respectively as of the Execution  Time and as of  the Closing Date, in  form
    and substance satisfactory to the Underwriters.

        (g)  Subsequent to the  Execution Time or,  if earlier, the  dates as of
    which information is given in  the Registration Statement (exclusive of  any
    amendment thereof) and the Prospectus (exclusive of any supplement thereto),
    there shall not have been (i) any change or decrease specified in the letter
    or  letters  referred to  in paragraph  (f) of  this Section  6 or  (ii) any
    change, or any development involving  a prospective change, in or  affecting
    the business or properties of the Company and its subsidiaries the effect of
    which,  in any  case referred  to in clause  (i) or  (ii) above,  is, in the
    judgment of  the  Underwriters,  so  material and  adverse  as  to  make  it
    impractical  or inadvisable to proceed with  the offering or delivery of the
    Securities as contemplated by the  Registration Statement (exclusive of  any
    amendment thereof) and the Prospectus (exclusive of any supplement thereto).

                                       13
<PAGE>
        (h) The Company shall have obtained and provided to the Underwriters, in
    form  and substance  satisfactory to the  Underwriters and  their counsel, a
    consent from the  lenders party  to the  Company's Credit  Agreement to  the
    transactions contemplated hereby and by the Indenture.

        (i)   Prior to the Closing Date, the Company shall have furnished to the
    Underwriters such  further information,  certificates and  documents as  the
    Underwriters may reasonably request.

    If  any of the  conditions specified in  this Section 6  shall not have been
fulfilled in all material respects when and as provided in this Agreement, or if
any of  the opinions  and  certificates mentioned  above  or elsewhere  in  this
Agreement  shall not be in all material respects reasonably satisfactory in form
and substance  to  the  Underwriters  and counsel  for  the  Underwriters,  this
Agreement  and all obligations of the Underwriters hereunder may be canceled at,
or at any time prior to, the Closing Date. Notice of such cancellation shall  be
given  to  the Company  in writing  or  by telephone  or telegraph  confirmed in
writing.

    7.  REIMBURSEMENT OF EXPENSES.

        (a) If the sale of the Securities provided for herein is not consummated
    because any condition to  the obligations of the  Underwriters set forth  in
    Section  6 hereof is  not satisfied, because of  any termination pursuant to
    Section 10 hereof  or because of  any refusal, inability  or failure on  the
    part  of the  Company to  perform any  agreement herein  or 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 proposed purchase and sale of the Securities.

        (b) The Underwriters  will reimburse the  Company for its  out-of-pocket
    expenses  relating to  the offering  of the Securities,  up to  a maximum of
    $150,000 ($172,500 if the over-allotment option is exercised in full).

    8.  INDEMNIFICATION AND CONTRIBUTION.

        (a) The Company agrees to indemnify and hold harmless each  Underwriter,
    the  directors, officers, employees and agents  of each Underwriter and each
    person who controls any Underwriter within the meaning of either the Act  or
    the Exchange Act against any and all losses, claims, damages or liabilities,
    joint  or several, to which they or any of them may become subject under the
    Act, the Exchange Act or other Federal or state statutory law or regulation,
    at common  law or  otherwise, insofar  as such  losses, claims,  damages  or
    liabilities  (or actions in respect thereof) arise  out of or are based upon
    any untrue  statement  or  alleged  untrue  statement  of  a  material  fact
    contained  in  the  registration  statement  for  the  registration  of  the
    Securities as  originally filed  or  in any  amendment  thereof, or  in  any
    Preliminary  Prospectus or  the Prospectus, or  in any  amendment thereof or
    supplement thereto,  or arise  out of  or  are based  upon 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,  and
    agrees  to reimburse each such indemnified party, as incurred, for any legal
    or  other  expenses   reasonably  incurred  by   them  in  connection   with
    investigating  or  defending  any  such loss,  claim,  damage,  liability or
    action; PROVIDED, HOWEVER, that the Company  will not be liable in any  such
    case to the extent that any such loss, claim, damage or liability arises out
    of or is based upon any such untrue statement or alleged untrue statement or
    omission or alleged omission made therein in reliance upon and in conformity
    with  written information furnished  to the Company  by or on  behalf of any
    Underwriter specifically  for inclusion  therein. This  indemnity  agreement
    will be in addition to any liability which the Company may otherwise have.

        (b) Each Underwriter severally agrees to indemnify and hold harmless the
    Company,  each of its directors, each of its officers, employees and agents,
    and each person who  controls the Company within  the meaning of either  the
    Act  or the Exchange Act, to the same extent as the foregoing indemnity from
    the Company  to  each  Underwriter,  but  only  with  reference  to  written
    information

                                       14
<PAGE>
    relating  to such Underwriter  furnished to the  Company by or  on behalf of
    such Underwriter specifically for inclusion in the documents referred to  in
    the foregoing indemnity. This indemnity agreement will be in addition to any
    liability  that any Underwriter may otherwise have. The Company acknowledges
    that the statements set forth in the last paragraph of the cover page and in
    the first, third and  sixth paragraphs under  the heading "Underwriting"  in
    any   Preliminary  Prospectus   and  the  Prospectus   constitute  the  only
    information furnished in writing by or on behalf of the several Underwriters
    for inclusion  in any  Preliminary  Prospectus or  the Prospectus,  and  you
    confirm that such statements are correct.

        (c)  Promptly after receipt by an indemnified party under this Section 8
    of notice of the commencement of any action, such indemnified party will, if
    a claim in  respect thereof  is to be  made against  the indemnifying  party
    under  this  Section 8,  notify  the indemnifying  party  in writing  of the
    commencement thereof; but the  failure so to  notify the indemnifying  party
    (i)  will not  relieve it  from liability under  paragraph (a)  or (b) above
    unless and to the extent it did not otherwise learn of such action and  such
    failure  results in the forfeiture by  the indemnifying party of substantial
    rights  and  defenses  and  (ii)  will  not,  in  any  event,  relieve   the
    indemnifying  party from any obligations to any indemnified party other than
    the indemnification obligation provided in  paragraph (a) or (b) above.  The
    indemnifying  party shall be entitled to appoint counsel of the indemnifying
    party's  choice  at  the  indemnifying  party's  expense  to  represent  the
    indemnified  party in  any action  for which  indemnification is  sought (in
    which case the indemnifying  party shall not  thereafter be responsible  for
    the  fees and expenses  of any separate counsel  retained by the indemnified
    party or parties except  as set forth below);  PROVIDED, HOWEVER, that  such
    counsel  shall be satisfactory to the indemnified party. Notwithstanding the
    indemnifying  party's  election   to  appoint  counsel   to  represent   the
    indemnified  party in an action, the  indemnified party shall have the right
    to employ separate counsel (including  local counsel), and the  indemnifying
    party  shall bear the  reasonable fees, costs and  expenses of such separate
    counsel if  (i) the  use of  counsel  chosen by  the indemnifying  party  to
    represent  the indemnified party would present  such counsel with a conflict
    of interest, (ii) the actual or potential defendants in, or targets of,  any
    such  action include both  the indemnified party  and the indemnifying party
    and the indemnified party shall have reasonably concluded that there may  be
    legal  defenses available  to it and/or  other indemnified  parties that are
    different from or additional to  those available to the indemnifying  party,
    (iii) the indemnifying party shall not have employed counsel satisfactory to
    the indemnified party to represent the indemnified party within a reasonable
    time after notice of the institution of such action or (iv) the indemnifying
    party  shall authorize the  indemnified party to  employ separate counsel at
    the expense  of the  indemnifying  party. An  indemnifying party  will  not,
    without  the prior  written consent  of the  indemnified parties,  settle or
    compromise or  consent to  the entry  of any  judgment with  respect to  any
    pending  or threatened claim, action, suit or proceeding in respect of which
    indemnification or contribution may be sought hereunder (whether or not  the
    indemnified parties are actual or potential parties to such claim or action)
    unless  such  settlement, compromise  or  consent includes  an unconditional
    release of each  indemnified party from  all liability arising  out of  such
    claim, action, suit or proceeding.

        (d)  In the event that the indemnity provided in paragraph (a) or (b) of
    this Section  8  is unavailable  to  or  insufficient to  hold  harmless  an
    indemnified  party for any reason, the Company and the Underwriters agree to
    contribute  to  the  aggregate  losses,  claims,  damages  and   liabilities
    (including  legal or other  expenses reasonably incurred  in connection with
    investigating or  defending  same)  (collectively  "Losses")  to  which  the
    Company  and  one  or  more  of the  Underwriters  may  be  subject  in such
    proportion as is appropriate  to reflect the  relative benefits received  by
    the  Company and  by the Underwriters  from the offering  of the Securities;
    PROVIDED, HOWEVER, that in no case  shall any Underwriter (except as may  be
    provided in any agreement among underwriters relating to the offering of the
    Securities)  be responsible  for any  amount in  excess of  the underwriting
    discount or  commission  applicable  to the  Securities  purchased  by  such
    Underwriter  hereunder.  If  the  allocation  provided  by  the  immediately
    preceding sentence  is  unavailable for  any  reason, the  Company  and  the
    Underwriters  shall  contribute  in  such proportion  as  is  appropriate to
    reflect not only such relative benefits  but also the relative fault of  the
    Company and of the Underwriters in

                                       15
<PAGE>
    connection  with the statements or omissions that resulted in such losses as
    well as any  other relevant equitable  considerations. Benefits received  by
    the  Company shall be deemed to be equal  to the total net proceeds from the
    offering  (before  deducting  expenses),   and  benefits  received  by   the
    Underwriters shall be deemed to be equal to the total underwriting discounts
    and  commissions,  in  each case  as  set forth  on  the cover  page  of the
    Prospectus. Relative fault shall be  determined by reference to whether  any
    alleged  untrue statement or omission relates to information provided by the
    Company or the Underwriters. The Company and the Underwriters agree that  it
    would  not be just and equitable if contribution were determined by pro rata
    allocation or any other method of  allocation that does not take account  of
    the   equitable  considerations  referred   to  above.  Notwithstanding  the
    provisions  of  this   paragraph  (d),  no   person  guilty  of   fraudulent
    misrepresentation  (within the meaning of Section 11(f) of the Act) shall be
    entitled to  contribution  from  any  person who  was  not  guilty  of  such
    fraudulent  misrepresentation. For purposes  of this Section  8, each person
    who controls an  Underwriter within  the meaning of  either the  Act or  the
    Exchange   Act  and  each  director,  officer,  employee  and  agent  of  an
    Underwriter shall have the same  rights to contribution as such  Underwriter
    and  each person who controls  the Company within the  meaning of either the
    Act or the Exchange Act, each officer  of the Company who shall have  signed
    the  Registration Statement and each director  of the Company shall have the
    same rights to  contribution as  the Company, subject  in each  case to  the
    applicable terms and conditions of this paragraph (d).

    9.   DEFAULT BY AN UNDERWRITER.  If  any one or more Underwriters shall fail
to purchase and pay  for any of  the Securities agreed to  be purchased by  such
Underwriter  or  Underwriters  hereunder  and  such  failure  to  purchase shall
constitute a default in the performance  of its or their obligations under  this
Agreement,  the remaining Underwriters  shall be obligated  severally to take up
and pay  for  (in  the  respective proportions  that  the  principal  amount  of
Securities  set forth  opposite their  names in Schedule  I hereto  bears to the
aggregate principal amount of Securities set forth opposite the names of all the
remaining Underwriters)  the  Securities  that  the  defaulting  Underwriter  or
Underwriters agreed but failed to purchase; PROVIDED, HOWEVER, that in the event
that   the  aggregate  principal  amount   of  Securities  that  the  defaulting
Underwriter or Underwriters agreed  but failed to purchase  shall exceed 10%  of
the aggregate principal amount of Securities set forth in Schedule I hereto, the
remaining  Underwriters shall have the  right to purchase all,  but shall not be
under  any  obligation  to  purchase  any,  of  the  Securities,  and  if   such
nondefaulting  Underwriters do not  purchase all the  Securities, this Agreement
will terminate  without  liability  to  any  nondefaulting  Underwriter  or  the
Company.  In the  event of  a default by  any Underwriter  as set  forth in this
Section 9, the Closing  Date shall be postponed  for such period, not  exceeding
seven  days, as you  shall determine in  order that the  required changes in the
Registration  Statement  and  the  Prospectus  or  in  any  other  documents  or
arrangements  may be effected. Nothing contained in this Agreement shall relieve
any defaulting Underwriter  of its  liability, if any,  to the  Company and  any
nondefaulting Underwriter for damages occasioned by its default hereunder.

    10.   TERMINATION.   This Agreement shall  be subject to  termination in the
absolute discretion of the Underwriters, by notice given to the Company prior to
delivery of and payment for the Securities, if prior to such time (i) trading in
the Company's Common Stock  shall have been suspended  by the Commission or  the
Nasdaq  National Market or trading in securities generally on the New York Stock
Exchange or the Nasdaq National Market  shall have been suspended or limited  or
minimum  prices shall have been  established on such Exchange  or Market, (ii) a
banking moratorium shall have been declared either by Federal or New York  State
authorities  or (iii)  there shall have  occurred any outbreak  or escalation of
hostilities, declaration by the United States of a national emergency or war  or
other  calamity or crisis the effect of which on financial markets is such as to
make it, in the judgment of the Representatives, impracticable or inadvisable to
proceed with the offering or delivery  of the Securities as contemplated by  the
Prospectus (exclusive of any supplement thereto).

    11.  REPRESENTATIONS AND INDEMNITIES TO SURVIVE.  The respective agreements,
representations,  warranties, indemnities and other statements of the Company or
its officers and  of the  Underwriters set  forth in  or made  pursuant to  this
Agreement  will remain in full force and effect, regardless of any investigation
made by or on behalf of any Underwriter  or the Company or any of the  officers,

    13.  SUCCESSORS.  This Agreement will inure to the benefit of and be binding
upon the  parties  hereto and  their  respective successors  and  the  officers,
directors,  employees, agents and  controlling persons referred  to in Section 8
hereof, and no other person will have any right or obligation hereunder.

    14.  APPLICABLE LAW.   This Agreement will be  governed by and construed  in
accordance with the laws of the State of New York.

Trustee shall act as such, and the Trustee shall initially act as such.
    

SECTION 2.04      PAYING AGENT TO HOLD MONEY IN TRUST.

      The Company shall require each Paying Agent (other than the Trustee, who
hereby so agrees), to agree in writing that the Paying Agent will hold in trust
for the benefit of holders of the Convertible Subordinated Notes or the Trustee
all money held by the Paying Agent for the payment of principal or interest on
the Convertible Subordinated Notes, and will notify the Trustee of any default
by the Company in respect of making any such payment.  While any such default
continues, the Trustee may require a Paying Agent to pay all money held by it to
the Trustee.  The Company at any time may require a Paying Agent to pay all
money held by it to the Trustee.  Upon payment over to the Trustee, the Paying
Agent (if other than the Company or a subsidiary of the Company) shall have no
further liability for the money.  If the Company or a subsidiary of the Company
acts as Paying Agent, it shall segregate and hold in a separate trust fund for
the benefit of the holders of the Convertible Subordinated Notes all money held
by it as Paying Agent.

SECTION 2.05      HOLDER LISTS.

      The Trustee shall preserve in as current a form as is reasonably
practicable the most recent list available to it of the names and addresses of
holders of Convertible Subordinated


                                        10
<PAGE>



   
Notes and shall otherwise comply with TIA Section 312(a).  If the Trustee
is Registrar, the Company shall furnish to the Trustee at least seven
business days before each Interest Payment Date and as the Trustee may
request in writing within fifteen (15) days after receipt by the Company of
any such request (or such lesser time as the Trustee may reasonably request
in order to enable it to timely provide any notice to be provided by it
hereunder) a list in such form and as of such date as the Trustee may
reasonably require of the names and addresses of holders of Convertible
Subordinated Notes.
    

SECTION 2.06      TRANSFER AND EXCHANGE.

   
      When Convertible Subordinated Notes are presented to the Registrar or a
co-registrar with a request to register a transfer or to exchange them for an
equal principal amount of Convertible Subordinated Notes for other
denominations, the Registrar shall register the transfer or make the exchange
if its requirements for such transactions are met.  To permit registrations
of transfers and exchanges, the Company shall issue and the Trustee shall
authenticate Convertible Subordinated Notes at the Registrar's request,
bearing registration numbers not contemporaneously outstanding.  No service
charge shall be made for any registration of transfer or exchange (except as
otherwise expressly permitted herein), but the Company may require payment of
a sum sufficient to cover any transfer tax or similar governmental charge
payable upon exchanges pursuant to Sections 2.10, 3.06, 9.05 or 12.02.
    

   
      The Company shall not be required (i) to issue, register the transfer
of or exchange Convertible Subordinated Notes during a period beginning at
the opening of business 15 days before the day of any selection of
Convertible Subordinated Notes for redemption under Section 3.02 and ending
at the close of business on the day of selection, (ii) to register the
transfer or exchange of any Convertible Subordinated Note so selected for
redemption in whole or in part, except the unredeemed portion of any
Convertible Subordinated Note being redeemed in part or (iii) to register the
transfer of any Convertible Subordinated Notes surrendered for repurchase
pursuant to Section 4.06.
    

   
      All Convertible Subordinated Notes issued upon any transfer or exchange
of Convertible Subordinated Notes in accordance with this Indenture shall be
the valid obligations of the Company, evidencing the same debt, and entitled
to the same benefits under this Indenture as the Convertible Subordinated
Notes surrendered upon such registration of transfer or exchange.
    

SECTION 2.07      REPLACEMENT CONVERTIBLE SUBORDINATED NOTES.

   
      If the holder of a Convertible Subordinated Note claims that the
Convertible Subordinated Note has been lost, destroyed or wrongfully taken,
the Company shall issue and the Trustee shall authenticate a replacement
Convertible Subordinated Note if the Trustee's requirements are met.  If
required by the Trustee or the Company as a condition of receiving a
replacement Convertible Subordinated Note, the holder of a Convertible
Subordinated Note must provide a certificate of loss and an indemnity and/or
an indemnity bond sufficient, in the judgment of both the Company and the
Trustee, to fully protect the Company, the Trustee, any Agent and any
authenticating agent from any loss, liability, cost or expense which any of
them may suffer or incur if the Convertible Subordinated Note is replaced.
The Company and the Trustee may charge the relevant holder for their expenses
in replacing any Convertible Subordinated Note.
    

   
      The Trustee or any authenticating agent may authenticate any such
substituted Convertible Subordinated Note, and deliver the same upon the
receipt of such security or indemnity as the Trustee, the Company and, if
applicable, such authenticating agent may require. Upon the issuance of any
substituted Convertible Subordinated Note, the Company may require the
payment of a sum sufficient to cover any tax or other governmental charge
that may be imposed in relation thereto and any other expenses connected
therewith. In case any Convertible Subordinated Note which has matured or is
about to mature, or has been called for redemption pursuant to Section 4.06
or is about to be converted into Common Stock shall become mutilated or be
destroyed, lost or stolen, the Company may, instead of issuing a substitute
Convertible Subordinated Note, pay or authorize the payment of or convert or
authorize the conversion of the same (without surrender thereof except in the
case of a mutilated Convertible Subordinated Note), as the case may be, if the
applicant for such payment or conversion shall furnish to the Company, to the
Trustee and, if applicable, to the authenticating agent such security or
indemnity as may be required by them to save each of them harmless for any
loss, liability, cost or expense caused by or connected with such
substitution, and, in case of destruction, loss or theft, evidence
satisfactory to the Company, the Trustee and, if applicable, any paying agent
or conversion agent of the destruction, loss or theft of such Convertible
Subordinated Note and of the ownership thereof.
    

      Every replacement Convertible Subordinated Note is an additional
obligation of the Company.

SECTION 2.08      OUTSTANDING CONVERTIBLE SUBORDINATED NOTES.

      The Convertible Subordinated Notes outstanding at any time are all the
Convertible Subordinated Notes properly authenticated by the Trustee except for
those cancelled by the Trustee, those delivered to it for cancellation, and
those described in this Section as not outstanding.

      If a Convertible Subordinated Note is replaced pursuant to Section 2.07,
it ceases to be outstanding unless the Trustee receives proof satisfactory to it
that the replaced Convertible Subordinated Note is held by a bona fide
purchaser.

   
      If Convertible Subordinated Notes are considered paid under Section
4.01 or converted under Article 12, they cease to be outstanding and interest
on them ceases to accrue.
    

      Subject to Section 2.09 hereof, a Convertible Subordinated Note does not
cease to be outstanding because the Company or an Affiliate of the Company holds
the Convertible Subordinated Note.

SECTION 2.09      WHEN TREASURY CONVERTIBLE SUBORDINATED NOTES DISREGARDED.

      In determining whether the holders of the required principal amount of
Convertible Subordinated Notes have concurred in any direction, waiver or
consent, Convertible Subordinated Notes owned by the Company or an Affiliate of
the Company shall be considered as though they are not outstanding except that
for the purposes of determining whether the Trustee shall be protected in
relying on any such direction, waiver or consent, only Convertible Subordinated
Notes which the Trustee knows are so owned shall be so disregarded.

SECTION 2.10      TEMPORARY CONVERTIBLE SUBORDINATED NOTES.

      Until definitive Convertible Subordinated Notes are ready for delivery,
the Company may prepare and the Trustee shall authenticate temporary Convertible
Subordinated Notes.  Temporary Convertible Subordinated Notes shall be
substantially in the form of definitive Convertible Subordinated Notes but may
have variations that the Company considers appropriate for temporary Convertible
Subordinated Notes.  If temporary Convertible Subordinated Notes are issued, the
Company will cause definitive Convertible Subordinated Notes to be prepared
without unreasonable delay.  After the preparation of definitive Convertible
Subordinated Notes, the temporary Convertible Subordinated Notes shall be
exchangeable for definitive Convertible Subordinated Notes upon surrender of the
temporary Convertible Subordinated Notes at any office or agency of the Company
designated pursuant to Section 2.03 without charge to the holder of the
Convertible Subordinated Note.  Upon surrender for cancellation of any one or
more temporary Convertible Subordinated Notes the Company shall execute and the
Trustee shall authenticate and deliver in exchange therefor a like principal
amount of definitive Convertible Subordinated Notes of authorized


                                        12
<PAGE>



denominations.  Until so exchanged, the temporary Convertible Subordinated Notes
shall in all respects be entitled to the same benefits under this Indenture as
definitive Convertible Subordinated Notes.

SECTION 2.11      CANCELLATION.

   
      The Company at any time may deliver Convertible Subordinated Notes to
the Trustee for cancellation.  The Registrar and Paying Agent shall forward
to the Trustee any Convertible Subordinated Notes surrendered to them for
registration of transfer, exchange or payment.  The Trustee and no one else
shall cancel Convertible Subordinated Notes surrendered for registration of
transfer, exchange, payment, replacement, conversion, redemption, repurchase
or cancellation and shall dispose of cancelled Convertible Subordinated Notes
as the Company directs, PROVIDED that the Trustee shall not be required to
destroy such Convertible Subordinated Notes.  The Company may not issue new
Convertible Subordinated Notes to replace Convertible Subordinated Notes that
it has paid, or that have been delivered to the Trustee for cancellation or
that any holder has converted pursuant to Article 12 hereof, redeemed
pursuant to Article 3 or repurchased pursuant to Section 4.06.
    

SECTION 2.12      DEFAULTED INTEREST.

      If the Company fails to make a payment of interest on the Convertible
Subordinated Notes, it shall pay such defaulted interest plus, to the extent
lawful, any interest payable on the defaulted interest.  It may pay such
defaulted interest, plus any such interest payable on it, to the persons who are
holders of Convertible Subordinated Notes on a subsequent special record date.
The Company shall fix any such record date and payment date.  At least 15 days
before any such record date, the Company shall mail to holders of the
Convertible Subordinated Notes a notice that states the record date, payment
date and amount of such interest to be paid.

SECTION 2.13      CUSIP NUMBER.

      The Company in issuing the Convertible Subordinated Notes may use a
"CUSIP" number, and if so, such CUSIP number shall be included in notices of
redemption or exchange as a convenience to holders of Convertible Subordinated
Notes; PROVIDED, HOWEVER, that any such notice may state that no
representation is made as to the correctness or accuracy of the CUSIP number
printed in the notice or on the Convertible Subordinated Notes and that reliance
may be placed only on the other identification numbers printed on the
Convertible Subordinated Notes.  The Company will promptly notify the Trustee of
any change in the CUSIP number.

                                  REDEMPTION

SECTION 3.01      NOTICES TO TRUSTEE.

   
      If the Company elects to redeem Convertible Subordinated Notes pursuant
to the optional redemption provisions of paragraph 5 of the Convertible
Subordinated Notes, it shall furnish to the Trustee, at least 15 (20 if less
than all of the then outstanding Convertible Subordinated Notes are to be
redeemed or if the Company requests the Trustee to give notice of redemption
pursuant to Section 3.03) days but not more than 60 days before a redemption
date (unless a shorter period shall be satisfactory to the Trustee), an
Officers' Certificate setting forth (i) the Section of this Indenture
pursuant to which the redemption shall occur, (ii) the redemption date, (iii)
the principal amount of Convertible Subordinated Notes to be redeemed (if
less than all) and (iv) the redemption price.
    

SECTION 3.02      SELECTION OF CONVERTIBLE SUBORDINATED NOTES TO BE REDEEMED.

   
      If less than all the Convertible Subordinated Notes are to be redeemed,
the Trustee shall select the Convertible Subordinated Notes to be redeemed by
lot or pro rata or by a method that complies with the requirements of any
exchange on which the Convertible Subordinated Notes are listed or quoted
that the Trustee considers fair and appropriate.  The Trustee shall make the
selection not more than 60 days and not less than 15 days before the
redemption date from Convertible Subordinated Notes outstanding not
previously called for redemption.  The Trustee may select for redemption
portions of the principal of Convertible Subordinated Notes that have a
denomination larger than $1,000 or integral multiple thereof. Convertible
Subordinated Notes and portions thereof will be redeemed in the amount of
$1,000 or integral multiples of $1,000.  Provisions of this Indenture that
apply to Convertible Subordinated Notes called for redemption also apply to
portions of Convertible Subordinated Notes called for redemption.  The
Trustee shall notify the Company promptly of the Convertible Subordinated
Notes or portions of Convertible Subordinated Notes to be called for
redemption.
    

SECTION 3.03      NOTICE OF REDEMPTION.

      At least 15 days but not more than 60 days before a redemption date, the
Company shall mail a notice of redemption to each holder whose Convertible
Subordinated Notes are to be redeemed.

      The notice shall identify the Convertible Subordinated Notes to be
redeemed and shall state:

            (1)   the redemption date;

            (2)   the redemption price;



                                        14
<PAGE>



            (3)   if any Convertible Subordinated Note is being redeemed in
      part, the portion of the principal amount of such Convertible Subordinated
      Note to be redeemed and that, after the redemption date, upon surrender of
      such Convertible Subordinated Note, a new Convertible Subordinated Note or
      Convertible Subordinated Notes in principal amount equal to the unredeemed
      portion will be issued;

            (4)   that Convertible Subordinated Notes called for redemption must
      be surrendered to the Paying Agent to collect the redemption price;

            (5)   that interest on Convertible Subordinated Notes called for
      redemption and for which funds have been set apart for payment, ceases to
      accrue on and after the redemption date (unless the Company defaults in
      the payment of the redemption price);

            (6)   the Paragraph of the Convertible Subordinated Notes pursuant
      to which the Convertible Subordinated Notes are being redeemed;

   
            (7)   the aggregate principal amount of Convertible Subordinated
      Notes (if less than all) that are being redeemed;
    

            (8)   the CUSIP number of the Convertible Subordinated Notes
      (PROVIDED that the disclaimer permitted by Section 2.13 may be made);

            (9)   the name and address of the Paying Agent;

            (10)  that Convertible Subordinated Notes called for redemption may
      be converted at any time prior to the close of business on the last
      trading day immediately preceding the redemption date and if not converted
      prior to the close of business on such date, the right of conversion will
      be lost; and

            (11)  that in the case of Convertible Subordinated Notes or portions
      thereof called for redemption on a date that is also an Interest Payment
      Date, the interest payment due on such date shall be paid to the person in
      whose name the Convertible Subordinated Note is registered at the close of
      business on the relevant Regular Record Date.

      At the Company's request, the Trustee shall give notice of redemption in
the Company's name and at its expense.

SECTION 3.04      EFFECT OF NOTICE OF REDEMPTION.

      Once notice of redemption is mailed, Convertible Subordinated Notes called
for redemption become due and payable on the redemption date at the redemption
price set forth in the Convertible Subordinated Note.


                                        15
<PAGE>



SECTION 3.05      DEPOSIT OF REDEMPTION PRICE.

      On or before the redemption date, the Company shall deposit with the
Trustee or with the Paying Agent money in immediately available funds sufficient
to pay the redemption price of and accrued interest on all Convertible
Subordinated Notes to be redeemed on that date.  The Trustee or the Paying Agent
shall return to the Company any money not required for that purpose.

   
       On and after the redemption date, unless the Company shall default in
the payment of the redemption price, interest will cease to accrue on the
principal amount of the Convertible Subordinated Notes or portions thereof
called for redemption and for which funds have been set apart for payment. In
the case of Convertible Subordinated Notes or portions thereof redeemed on a
redemption date which is also an Interest Payment Date, the interest payment
due on such date shall be paid to the person in whose name the Convertible
Subordinated Note is registered at the close of business on the relevant
Regular Record Date.
    

SECTION 3.06      CONVERTIBLE SUBORDINATED NOTES REDEEMED IN PART.

      Upon surrender of a Convertible Subordinated Note that is redeemed in
part, the Company shall issue and the Trustee shall authenticate for the holder
of a Convertible Subordinated Note at the expense of the Company a new
Convertible Subordinated Note equal in principal amount to the unredeemed
portion of the Convertible Subordinated Note surrendered.

   
SECTION 3.07    CONVERSION ARRANGEMENT ON CALL FOR REDEMPTION.

       In connection with any redemption of Convertible Subordinated Notes,
the Company may arrange for the purchase and conversion of any Convertible
Subordinated Notes by an arrangement with one or more investment bankers or
other purchasers to purchase such Convertible Subordinated Notes by paying to
the Trustee in trust for the holders, on or before the date fixed for
redemption, an amount not less than the applicable redemption price, together
with interest accrued to the date fixed for redemption, of such Convertible
Subordinated Notes. Notwithstanding anything to the contrary contained in
this Article 3, the obligation of the Company to pay the redemption price of
such Convertible Subordinated Notes, together with interst accrued to the
date fixed for redemption, shall be deemed to be satisfied and discharged to
the extent such amount is so paid by the purchasers. If such an agreement is
entered into, a copy of which will be filed with the Trustee prior to the
dated fixed for redemption, any Convertible Subordinated Notes not duly
surrendered for conversion by the holders thereof may, at the option of the
Company, be deemed, to the fullest extent permitted by law, acquired by such
purchasers from such holders and (notwithstanding anything to the contrary
contained in Article 12) surrendered by such purchasers for conversion, all
as of immediately prior to the close of business on the date fixed for
redemption (and the right to convert any such Convertible Subordinated Notes
shall be deemed to have been extended through such time), subject to payment
of the above amount as aforesaid. At the direction of the Company, the
Trustee shall hold and dispose of any such amount paid to it in the same
manner as it would monies deposited with it by the Company for the redemption
of Convertible Subordinated Notes. Without the Trustee's prior written
consent, no arrangement between the Company and such purchasers for the
purchase and conversion of any Convertible Subordinated Notes shall increase
or otherwise affect any of the powers, duties, responsibilities or
obligations of the Trustee as set forth in this Indenture, and the Company
agrees to indemnify the Trustee from, and hold it harmless against, any loss,
liability or expense arising out of or in conversion of any Convertible
Subordinated Notes between the Company and such purchasers to which the
Trustee has not consented in writing, including the costs and expenses
incurred by the Trustee in the defense of any claim or liability arising out
of or in connection with the exercise or performance of any of its powers,
duties, responsibilities or obligations under this Indenture.

      The Company shall pay the principal of and interest on the Convertible

Trustee or Paying Agent (other than the Company or a subsidiary of the
Company) holds as of 10:00 a.m. New York City time on that date immediately
available funds designated for and sufficient to pay all principal, interest,
the redemption price and the Designated Event Payment then due, PROVIDED,
HOWEVER, that money held by the Agent for the benefit of holders of Senior
Debt pursuant to the provisions of Article 11 hereof or the payment of which
to the holders of the Convertible Subordinated Notes is prohibited by Article
11 shall not be considered to be designated for the payment of any principal
of or interest on the Convertible Subordinated Notes within the meaning of
this Section 4.01.
    

      To the extent lawful, the Company shall pay interest (including
post-petition interest in any proceeding under any Bankruptcy Law) on (i)
overdue principal, at the rate borne by Convertible Subordinated Notes,
compounded semiannually; and (ii) overdue installments of


                                        16

review of the activities of the Company and its subsidiaries during the
preceding fiscal year has been made under the supervision of the signing
Officers with a view to determining whether the Company has fully performed
its obligations under this Indenture and further stating, as to each such
Officer signing such certificate, that to the best of his or her knowledge,
the Company is not in default in the performance or observance of any of the
terms and conditions hereof (or, if any Default or Event of Default shall
have occurred, describing all such Defaults or Events of Default of which he
or she may have knowledge) and, that to the best of his or her knowledge, no
event has occurred and remains in existence by reason of which payments on
account of the principal of or interest on the Convertible Subordinated Notes
are prohibited.
    

   
      The Company shall, so long as any of the Convertible Subordinated Notes
are outstanding, deliver to the Trustee, forthwith upon becoming aware of any
Default or Event of Default, an Officers' Certificate specifying such Default
or Event of Default.
    

SECTION 4.04      MAINTENANCE OF OFFICE OR AGENCY.

      The Company shall maintain or cause to be maintained the office or agency
required under Section 2.03.  The Company shall give prompt written notice to
the Trustee of the location, and any change in the location, of such office or
agency not maintained by the Trustee.  If at any time the Company shall fail to
maintain any such required office or agency or shall fail to furnish the Trustee
with the address thereof, presentations, surrenders, notices and demands with
respect to the Convertible Subordinated Notes may be made or served at the
Corporate Trust Office of the Trustee.

      The Company may also from time to time designate one or more other offices
or agencies where the Convertible Subordinated Notes may be presented or
surrendered for any or all such purposes and may from time to time rescind such
designation.

SECTION 4.05      CONTINUED EXISTENCE.

   
      Subject to Article 5, the Company shall do or cause to be done all
things necessary to preserve and keep in full force and effect its corporate
existence.
    

   
SECTION 4.06      REPURCHASE UPON DESIGNATED EVENT.

      Following a Designated Event (the date of each such occurrence being
the "Designated Event Date"), the Company shall notify the holders of
Convertible Subordinated Notes in writing of such occurrence and shall make
an offer (the "Designated Event Offer") to repurchase all Convertible
Subordinated Notes then outstanding at a repurchase price (the "Designated
Event Payment") equal to 101% of the principal amount thereof, plus accrued

<PAGE>

   

            (b)   the Company defaults in the payment (whether or not such
      payment is prohibited by the subordination provisions of Article 11 of
      this Indenture) of any installment of interest on the Convertible
      Subordinated Notes when due (including any interest payable in connection
      with a repurchase pursuant to Section 4.06 or in connection with any
      optional redemption payment pursuant to Article 3) and continuance of
      such default for more than 30 days; or

    

            (c)   the Company defaults (other than a default set forth in
      clauses (a) and (b) above) in the performance of, or breach of, any other
      covenant or warranty of the Company set forth in this Indenture or the
      Convertible Subordinated Notes and fails to remedy such default or breach

      Trustee or the holders of at least 25% in aggregate principal amount of
      the then outstanding Convertible Subordinated Notes; or

   

            (d)   the Company fails to provide notice of any Designated Event in
      accordance with Section 4.06; or

    

   

            (e)   failure of the Company or any Material Subsidiary to make any
      payment at maturity, including any applicable grace period, in respect of
      indebtedness for borrowed money of, or guaranteed or assumed by, the
      Company or any Material Subsidiary which payment in an amount in excess
      of $25,000,000 and continuance of such failure for 30 days after notice
      thereof from the Trustee or the holders of at least 25% in aggregate
      principal amount of the then outstanding Convertible Subordinated Notes;
      or

    

   
            (f)   default by the Company or any Material Subsidiary with respect
      to any indebtedness referred to in clause (e) above which default results
      in the acceleration of any such indebtedness of an amount in excess of
      $25,000,000 without such indebtedness having been paid or discharged or
      such acceleration having been cured, waived, rescinded or annulled for 30
      days after notice thereof from the Trustee or the holders of at least 25%
      in aggregate principal amount of the then outstanding Convertible
      Subordinated Notes; or

    

   
            (g)   the Company or any Material Subsidiary, pursuant to or within
      the meaning of any Bankruptcy Law:

    

                  (i)   commences a voluntary case,

                  (ii)  consents to the entry of an order for relief against it
            in an involuntary case,

                  (iii) consents to the appointment of a Custodian of it or for

                                        23
<PAGE>



                  (iv)  makes a general assignment for the benefit of its
            creditors; or

            (h)   a court of competent jurisdiction enters a judgment, order or
      decree under any Bankruptcy Law that:

                  (i)   is for relief against the Company or any Material
            Subsidiary in an involuntary case,

   

                  (ii)  appoints a Custodian of the Company or any Material
            Subsidiary, and the order or decree remains unstayed and in effect
            for 90 days.

    

                  (iii) orders the liquidation of the Company or any Material
            Subsidiary, and the order or decree remains unstayed and in effect
            for 90 days.

      The term "Bankruptcy Law" means title 11, U.S. Code or any similar Federal
or state law for the relief of debtors.  The term "Custodian" means any
receiver, trustee, assignee, liquidator or similar official under any Bankruptcy
Law.

            In the case of any Event of Default pursuant to the provisions of
this Section 6.01 occurring by reason of any willful action (or inaction) taken
(or not taken) by or on behalf of the Company with the intention of avoiding
payment of the premium which the Company would have had to pay if the Company
then had elected to redeem the Convertible Subordinated Notes pursuant to
Paragraph 5 of the Convertible Subordinated Notes of this Indenture, an
equivalent premium shall also become and be immediately due and payable to the
extent permitted by law, anything in this Indenture or in the Convertible
Subordinated Notes contained to the contrary notwithstanding.

   

            If an Event of Default occurs prior to any date on which the
Comapny is prohibited from redeeming the Convertible Subordinated Notes
pursuant to the optional redemption provisions of Article 3 of this Indenture
by reason of any wilful action (of inaction) taken (or not taken) by or on
behalf of the Company with the intention of avoiding the prohibition on
redemption of the Convertible Subordinated Notes prior to such date, then the
premium specified in this Indenture shall also become immediately due and
payable to the extent permitted by law upon the acceleration of the
Convertible Subordinated Notes.

    

SECTION 6.02      ACCELERATION.

      If an Event of Default (other than an Event of Default specified in
clauses (g) and (h) of Section 6.01) occurs and is continuing, then and in every
such case the Trustee, by written notice to the Company, or the holders of at
least 25% in aggregate principal amount of the then outstanding Convertible
Subordinated Notes, by written notice to the Company and the Trustee, may
declare the unpaid principal of and accrued interest on all the Convertible
Subordinated Notes to be due and payable.  Upon such declaration such principal
amount, premium, if any, and accrued and unpaid interest shall become
immediately due and payable, notwithstanding anything contained in this
Indenture or the Convertible Subordinated Notes to the contrary but subject to
the provisions of Article 11 hereof.  If any Event of Default with respect to
the Company specified in clauses (g) or (h) of Section 6.01 occurs, all unpaid
principal of and premium, if any, and accrued and unpaid interest on the
Convertible Subordinated Notes then outstanding shall become automatically due
and payable subject to


                                        24
<PAGE>



the provisions of Article 11 hereof, without any declaration or other act on the
part of the Trustee or any holder of Convertible Subordinated Notes.

   

      The holders of a majority in aggregate principal amount of the then
outstanding Convertible Subordinated Notes by notice to the Trustee may
rescind an acceleration of the Convertible Subordinated Notes and its
consequences if all existing Events of Default (other than nonpayment of
principal of or premium, if any, and interest on the Convertible Subordinated
Notes which has become due solely by virtue of such acceleration) have been
cured or waived and if the rescission would not conflict with any judgment or
decree of any court of competent jurisdiction.  No such rescission shall
affect any subsequent Default or Event of Default or impair any right
consequent thereto.

    

SECTION 6.03      OTHER REMEDIES.

      If an Event of Default occurs and is continuing, the Trustee may pursue
any available remedy by proceeding at law or in equity to collect the payment of
principal of or interest on the Convertible Subordinated Notes or to enforce the
performance of any provision of the Convertible Subordinated Notes or this
Indenture.  The Trustee may maintain a proceeding even if it does not possess
any of the Convertible Subordinated Notes or does not produce any of them in the
proceeding.  A delay or omission by the Trustee or any holder of a Convertible
Subordinated Note in exercising any right or remedy occurring upon an Event of
Default shall not impair the right or remedy or constitute a waiver of or
acquiescence in the Event of Default.  All remedies are cumulative to the extent
permitted by law.

SECTION 6.04      WAIVER OF PAST DEFAULTS.

      The holders of a majority in aggregate principal amount of the Convertible
Subordinated Notes then outstanding may, on behalf of the holders of all the
Convertible Subordinated Notes waive an existing Default or Event of Default and
its consequences, except a Default or Event of Default in the payment of the
principal of or interest on the Convertible Subordinated Notes (other than the
non-payment of principal of and premium, if any, and interest on the Convertible
Subordinated Notes which has become due solely by virtue of an acceleration
which has been duly rescinded as provided above), or in respect of a covenant or
provision of this Indenture which cannot be modified or amended without the
consent of all holders of Convertible Subordinated Notes.  When a Default is
waived, it is cured and stops continuing.  No waiver shall extend to any
subsequent or other Default or impair any right consequent thereon.

SECTION 6.05      CONTROL BY MAJORITY.

   

      The holders of a majority in principal amount of the then outstanding
Convertible Subordinated Notes may direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee or exercising
any trust or power conferred on it.  However, the Trustee may refuse to follow
any direction that conflicts with law or this


                                        25
<PAGE>

Indenture that the Trustee determines may be unduly prejudicial to the rights
of other holders of Convertible Subordinated Notes or that may involve the
Trustee in personal liability; PROVIDED, that the Trustee shall have no duty
or obligation (subject to Section 7.01) to ascertain whether or not such
actions of forebearances are unduly prejudicial to such holders; PROVIDED
FURTHER, that the Trustee may take any other action the Trustee deems proper
that is not inconsistent with such directions.

    

SECTION 6.06      LIMITATION ON SUITS.

      A holder of a Convertible Subordinated Note may not pursue any remedy with
respect to this Indenture or the Convertible Subordinated Notes unless:

            (1)   the holder gives to the Trustee notice of a continuing Event
      of Default;

            (2)   the holders of at least 25% in principal amount of the then
      outstanding Convertible Subordinated Notes make a request to the Trustee
      to pursue the remedy;

            (3)   such holder or holders offer and, if requested, provide to the
      Trustee indemnity satisfactory to the Trustee against any loss, liability
      or expense;

            (4)   the Trustee does not comply with the request within 60 days
      after receipt of the request and the offer and, if requested, the
      provision of indemnity; and

            (5)   during such 60-day period the holders of a majority in
      principal amount of the then outstanding Convertible Subordinated Notes do
      not give the Trustee a direction inconsistent with the request.

      A holder of a Convertible Subordinated Note may not use this Indenture to
prejudice the rights of another holder or to obtain a preference or priority
over another holder.

SECTION 6.07      RIGHTS OF HOLDERS TO RECEIVE PAYMENT.

   

      Subject to the provisions of Article 11 hereof, notwithstanding any
other provision of this Indenture, the right of any holder of a Convertible
Subordinated Note to receive payment of principal, premium, if any, and
interest on the Convertible Subordinated Note, on or after the respective due
dates expressed in the Convertible Subordinated Note, or to bring suit for
the enforcement of any such payment on or after such respective dates, or to
bring suit for the enforcement of the right to convert the Convertible
Subordinated Note shall not be impaired or affected without the consent of
the holder of a Convertible Subordinated Note.

    

SECTION 6.08      COLLECTION SUIT BY TRUSTEE.

      If an Event of Default specified in Section 6.01(a) or (b) occurs and is
continuing, the Trustee may recover judgment in its own name and as trustee of
an express trust against the Company for the whole amount of principal and
interest remaining unpaid on the Convertible Subordinated Notes and interest on
overdue principal and interest and such further amount as


                                        26
<PAGE>



shall be sufficient to cover the costs and, to the extent lawful, expenses of
collection, including the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel.

SECTION 6.09      TRUSTEE MAY FILE PROOFS OF CLAIM.

      The Trustee may file such proofs of claim and other papers or documents as
may be necessary or advisable in order to have the claims of the Trustee and the
holders of Convertible Subordinated Notes allowed in any judicial proceedings
relative to the Company, its creditors or its property.  Nothing contained
herein shall be deemed to authorize the Trustee to authorize or consent to or
accept or adopt on behalf of any holder of a Convertible Subordinated Note any
plan of reorganization, arrangement, adjustment or composition affecting the
Convertible Subordinated Notes or the rights of any holder thereof, or to
authorize the Trustee to vote in respect of the claim of any holder in any such
proceeding.

SECTION 6.10      PRIORITIES.

      If the Trustee collects any money pursuant to this Article, it shall pay
out the money in the following order:

            First: to the Trustee for amounts due under Section 7.07, including
      payment of all compensation, expenses and liabilities incurred, and all
      advances made, by the Trustee, and the costs and expenses of collection;

            Second: to holders of Senior Debt to the extent required by Article
      11;

   

            Third: to holders of Convertible Subordinated Notes for amounts due
      and unpaid on the Convertible Subordinated Notes for principal, premium,
      if any, and interest, ratably, without preference or priority of any
      kind, according to the amounts due and payable on the Convertible
      Subordinated Notes for principal, premium, if any, and interest,
      respectively; and

    

            Fourth: to the Company.

      Except as otherwise provided in Section 2.12, the Trustee may fix a record
date and payment date for any payment to holders of Convertible Subordinated
Notes.

SECTION 6.11      UNDERTAKING FOR COSTS.

      In any suit for the enforcement of any right or remedy under this
Indenture or in any suit against the Trustee for any action taken or omitted by
it as a Trustee, a court in its discretion may require the filing by any party
litigant in the suit, other than the Trustee, of an undertaking to pay the costs
of the suit, and the court in its discretion may assess reasonable costs,
including reasonable attorneys fees, against any party litigant in the suit,
having due regard to the merits and good faith of the claims or defenses made by
the party


                                        27

principal amount of the then outstanding Convertible Subordinated Notes.


                                   ARTICLE 7

SECTION 7.01      DUTIES OF THE TRUSTEE.

      (a)   If an Event of Default known to the Trustee has occurred and is
continuing, the Trustee shall exercise such of the rights and powers vested in
it by this Indenture and use the same degree of care and skill in their exercise
as a prudent person would exercise or use under the circumstances in the conduct
of his or her own affairs.

      (b)   Except during the continuance of an Event of Default known to the

            (1)   The duties of the Trustee shall be determined solely by the
      express provisions of this Indenture and the Trustee need perform only
      those duties that are specifically set forth in this Indenture and no
      others and no implied covenants or obligations shall be read into this
      Indenture against the Trustee; and

   

            (2)   In the absence of bad faith on its part, the Trustee may
      conclusively rely, as to the truth of the statements and the correctness
      of the opinions expressed therein, upon any statements, certificates or
      opinions furnished to the Trustee and conforming to the requirements of
      this Indenture. However, the Trustee shall examine the certificates and
      opinions to determine whether or not they conform to the form required by
      this Indenture.

facts or matters stated in any resolution, certificate, statement, instrument,
opinion, report, notice, request, consent, order, security or other document
unless requested in writing to do so by the holders of not less than a majority
in aggregate principal amount of the Convertible Subordinated Notes then
outstanding, PROVIDED that if the Trustee determines in its sole and absolute
discretion to make any such investigation, then it shall be entitled, upon
reasonable prior notice and during normal business hours, to examine the books
and records and the premises of the Company, personally or by agent or attorney,
and the reasonable expenses of every such examination shall be paid by the
Company or, if paid by the Trustee or any predecessor Trustee, shall be
reimbursed by the Company upon demand.

   
      (i)   The permissive rights of the Trustee to do things enumerated in
this Indenture shall not be construed as a duty and the Trustee shall not be
answerable for other than its negligence or willful misconduct.
    

   
     [(j)   Except for (i) a default under Sections [5.01(a) or (b)] hereof,
or (ii) any other event of which the Trustee has "actual knowledge" and which
event, with the giving of notice or the passage of time or both, would
constitute an Event of Default under this Indenture, the Trustee shall not be
deemed to have notice of an default or event unless specifically notified in
writing of such event by the Company or the holders of not less than 25% in
aggregate principal amount of the Convertible Subordinated Notes then
outstanding; as used herein, the term "actual knowledge" means the actual
fact or statement of knowing, without any duty to make any investigation with
regard thereto.]
    

   
      (k)   The Trustee shall not be responsible for the computation of any
adjustment to the Conversion Price or for any determination as to whether an
adjustment is required.
    

SECTION 7.03      INDIVIDUAL RIGHTS OF THE TRUSTEE.

   
      Subject to Sections 7.10 and 7.11, the Trustee in its individual or any
other capacity may become the owner or pledgee of Convertible Subordinated
Notes with the same rights it would have if it were not the Trustee and may
otherwise deal with the Company or an Affiliate and receive, collect, hold
and retain collections from the Company with the same rights it would have if
it were not Trustee.  Any Agent may do the same with like rights.
    

SECTION 7.04      TRUSTEE'S DISCLAIMER.

      The Trustee shall not be responsible for and makes no representation as to
the validity or adequacy of this Indenture or the Convertible Subordinated
Notes.  It shall not be accountable for the Company's use of the proceeds from
the Convertible Subordinated Notes or any money paid to the Company or upon the
Company's direction under any provision of this Indenture.  It shall not be
responsible for the use or application of any money received by any Paying Agent

recital herein or any statement in the Convertible Subordinated Notes or any
other document in connection with the sale of the Convertible Subordinated Notes
or pursuant to this Indenture other than its certificate of authentication.

SECTION 7.05      NOTICE OF DEFAULTS.

      If a Default or Event of Default occurs and is continuing and if it is
known to the Trustee, the Trustee shall mail to each holder of a Convertible
Subordinated Note a notice of the Default or Event of Default within 60 days
after it occurs.  A Default or an Event of Default shall not be considered known
to the Trustee unless it is a Default or Event of Default in the payment of
principal or interest when due under Section 6.01(a) or (b) or the Trustee shall
have received notice thereof, in accordance with this Indenture, from the
Company or from the holders of a majority in principal amount of the outstanding
Convertible Subordinated Notes.  Except in the case of a Default or Event of
Default in payment of principal of, premium, if any, or interest on any
Convertible Subordinated Note, the Trustee may withhold the notice if and so
long as a committee of its Trust Officers in good faith determines that
withholding the notice is in the interest of the holders of the Convertible
Subordinated Notes.

SECTION 7.06      REPORTS BY THE TRUSTEE TO HOLDERS.

      Within 60 days after the reporting date stated in Section 10.10, the
Trustee shall mail to holders of Convertible Subordinated Notes a brief report
not the dated as of such reporting date that complies with TIA Section 313(a)
described in TIA Section 313(a) has occurred within twelve months preceding the
reporting date, no report need be transmitted).  The Trustee also shall comply
(but if no event with TIA Section 313(b)(2).  The Trustee shall also transmit by
required by TIA Section 313(c).

      A copy of each report at the time of its mailing to holders of Convertible
Subordinated Notes shall be filed, at the expense of the Company, by the Trustee
with the Commission and each stock exchange or securities market, if any, on
which the Convertible Subordinated Notes are listed.  The Company shall timely
notify the Trustee when the Convertible Subordinated Notes are listed or quoted
on any stock exchange or securities market.

SECTION 7.07      COMPENSATION AND INDEMNITY.

      The Company shall pay to the Trustee from time to time and the Trustee
shall be entitled to reasonable compensation for its acceptance of this
Indenture and its services hereunder.  The Trustee's compensation shall not be
limited by any law on compensation of a trustee of an express trust.  The
Company shall reimburse the Trustee promptly upon request for all reasonable
disbursements, advances and expenses incurred or made by or on behalf of it in
addition to the compensation for its services.  Such expenses may include the
reasonable compensation, disbursements and expenses of the Trustee's agents,
counsel and other persons not regularly in its employ.

      The Company shall indemnify the Trustee against any loss, liability or
expense incurred by it arising out of or in connection with the acceptance or
administration of its


                                        31
<PAGE>



duties under this Indenture and the trusts hereunder, including the costs and
expenses of defending itself against or investigating any claim of liability in
the premises, except as set forth in the next paragraph.  The Trustee shall
notify the Company promptly of any claim for which it may seek indemnity.
Failure by the Trustee to so notify the Company shall not relieve the Company of
its obligations hereunder.  The Company shall defend the claim with counsel
designated by the Company, who may be outside counsel to the Company but shall
in all events be reasonably satisfactory to the Trustee, and the Trustee shall
cooperate in the defense.  In addition, the Trustee may retain one separate
counsel and, if deemed advisable by such counsel, local counsel, and the Company
shall pay the reasonable fees and expenses of such separate counsel and local
counsel.  The indemnification herein extends to any settlement, PROVIDED that
the Company will not be liable for any settlement made without its consent,
provided, further, that such consent will not be unreasonably withheld.

   
      The Company need not reimburse any expense or indemnify against any loss
or liability incurred by the Trustee through its own negligence or willful
misconduct.
    

      To secure the Company's payment obligations in this Section 7.07, the
Trustee shall have a Lien prior to the Convertible Subordinated Notes on all
money or property held or collected by the Trustee, except that held in trust to
pay principal and interest on Convertible Subordinated Notes.  Such Liens and
the Company's obligations under this Section 7.07 shall survive the satisfaction
and discharge of this Indenture.

   
      When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 6.01(g) or (h) occurs, the expenses and the
compensation for the services (including the fees and expenses of its agents and
counsel) are intended to constitute expenses of administration under any
Bankruptcy Law.
    

SECTION 7.08      REPLACEMENT OF THE TRUSTEE.

      A resignation or removal of the Trustee and appointment of a successor
Trustee shall become effective only upon the successor Trustee's acceptance of
appointment as provided in this Section 7.08.

      The Trustee may resign at any time and be discharged from the trust hereby
created by so notifying the Company.  The holders of a majority in principal
amount of the then outstanding Convertible Subordinated Notes may remove the
Trustee by so notifying the Trustee and the Company in writing and may appoint a
successor Trustee.  The Company may remove the Trustee if:

            (1) the Trustee fails to comply with Section 7.10;

            (2) the Trustee is adjudged a bankrupt or an insolvent or an order
      for relief is entered with respect to the Trustee under any Bankruptcy
      Law;

            (3) a Custodian or public officer takes charge of the Trustee or its
      property; or

            (4) the Trustee becomes incapable of acting.

      If the Trustee resigns or is removed or if a vacancy exists in the office
of Trustee for any reason, the Company shall promptly appoint a successor
Trustee.  Within one year after the successor Trustee takes office, the holders
of a majority in principal amount of the then outstanding Convertible
Subordinated Notes may appoint a successor Trustee to replace the successor
Trustee appointed by the Company.

      If a successor Trustee does not take office within 60 days after the
retiring Trustee resigns or is removed, the retiring Trustee, the Company or the
holders of at least 10% in principal amount of the then outstanding Convertible
Subordinated Notes may petition any court of competent jurisdiction for the
appointment of a successor Trustee.

      If the Trustee after written request by any holder of a Convertible
Subordinated Note who has been a holder for at least six months fails to comply
with Section 7.10, such holder may petition any court of competent jurisdiction
for the removal of the Trustee and the appointment of a successor Trustee.

      A successor Trustee shall deliver a written acceptance of its appointment
to the retiring Trustee and to the Company.  Thereupon the resignation or
removal of the retiring Trustee shall become effective, and the successor
Trustee shall have all the rights, powers and duties of the Trustee under this
Indenture.  The successor Trustee shall mail a notice of its succession to
holders of Convertible Subordinated Notes.  The retiring Trustee shall promptly
transfer all property held by it as Trustee to the successor Trustee, PROVIDED
that all sums owing to the retiring Trustee hereunder have been paid and subject
to the lien provided for in Section 7.07.  Notwithstanding the replacement of
the Trustee pursuant to this Section 7.08, the Company's obligations under
Section 7.07 shall continue for the benefit of the retiring Trustee.

      Upon request of any such successor Trustee, the Company shall execute any
and all instruments for more fully and certainly vesting in and confirming to
such successor Trustee all such rights, powers and trusts referred to in the
preceding paragraph.

SECTION 7.09      SUCCESSOR TRUSTEE BY MERGER, ETC.

      If the Trustee consolidates with, merges or converts into, or transfers
all or substantially all of its corporate trust business to, another corporation
or national banking association, the resulting, surviving or transferee
corporation or national banking association without any further act shall be the
successor Trustee with the same effect as if the successor Trustee had been
named as the Trustee herein.

SECTION 9.02      WITH THE CONSENT OF HOLDERS.

      Subject to Section 6.07, the Company and the Trustee may amend this
Indenture or the Convertible Subordinated Notes with the written consent of the
holders of at least a majority in principal amount of the then outstanding
Convertible Subordinated Notes (including consents obtained in connection with a

amount of the Convertible Subordinated Notes then outstanding may also waive
compliance in a particular instance by the Company with any provision of this
Indenture or the Convertible Subordinated Notes.

      However, without the consent of each holder of a Convertible Subordinated
Note affected, an amendment or waiver under this Section may not:

            (a)   reduce the principal amount of Convertible Subordinated Notes
      whose holders must consent to an amendment, supplement or waiver;

   
            (b)   reduce the principal of or premium on or change the fixed

            (d)   waive a Default or Event of Default in the payment of
      principal of or premium, if any, or interest on the Convertible
      Subordinated Notes (except a rescission of acceleration of the Convertible
      Subordinated Notes by the holders of at least a majority in aggregate
      principal amount of the Convertible Subordinated Notes then outstanding
      and a waiver of the payment default that resulted from such acceleration);

            (e)   make the principal of, or premium, if any, or interest on, any
      Convertible Subordinated Note payable in money other than as provided for
      herein and in the Convertible Subordinated Notes;

            (f)   waive a redemption payment with respect to any Convertible

      contained herein relating to conversion of the Convertible Subordinated
      Notes in a manner adverse to the holders thereof; or
    


                                        37

            (h)   make any change in provisions relating to waivers of defaults,
      or the rights of holders of Convertible Subordinated Notes to receive
      payments of principal of, premium, if any, or interest on the Convertible
      Subordinated Notes or the abilities of holders of Convertible Subordinated
      Notes to enforce their rights hereunder or the provisions of clauses (a)
      through (h) of this Section 9.02.

      To secure a consent of the holders of Convertible Subordinated Notes under
this Section, it shall not be necessary for such holders to approve the
particular form of any proposed amendment or waiver, but it shall be sufficient
if such consent approves the substance thereof.

      After an amendment or waiver under this Section becomes effective, the
Company shall mail to holders of Convertible Subordinated Notes a notice briefly
describing the amendment or waiver.

principal amount of Convertible Subordinated Notes then outstanding must consent

Convertible Subordinated Notes.

SECTION 9.03      COMPLIANCE WITH THE TRUST INDENTURE ACT.

      Every amendment to this Indenture or the Convertible Subordinated Notes
shall be set forth in a supplemental indenture that complies with the TIA as
then in effect.

SECTION 9.04      REVOCATION AND EFFECT OF CONSENTS.

      Until an amendment or waiver becomes effective, a consent to it by a
holder of a Convertible Subordinated Note is a continuing consent by the holder
and every subsequent holder of a Convertible Subordinated Note or portion of a
Convertible Subordinated Note that evidences the same debt as the consenting
holder's Convertible Subordinated Note, even if notation of the consent is not
made on any Convertible Subordinated Note.  However, any such holder or
subsequent holder may revoke the consent as to his or her Convertible
Subordinated Note or portion of a Convertible Subordinated Note if the Trustee
receives the notice of revocation before the date on which the Trustee receives
an Officers' Certificate certifying that the holders of the requisite principal
amount of Convertible Subordinated Notes have consented to the amendment or
waiver.

      The Company may, but shall not obligated to, fix a record date for the
purpose of determining the holders of Convertible Subordinated Notes entitled to
consent to any amendment or waiver.  If a record date is fixed, then
notwithstanding the provisions of the immediately preceding paragraph, those
persons who were holders of Convertible Subordinated Notes at such record date
(or their duly designated proxies), and only those persons, shall be entitled to
consent to such amendment or waiver or to revoke any consent


                                        38
<PAGE>



previously given, whether or not such persons continue to be holders after such
record date.  No consent shall be valid or effective for more than 90 days after
such record date unless consents from holders of the principal amount of
Convertible Subordinated Notes required hereunder for such amendment or waiver
to be effective shall have also been given and not revoked within such 90-day
period.

      After an amendment or waiver becomes effective it shall bind every holder
of a Convertible Subordinated Note, unless it is of the type described in
clauses (a) - (h) of Section 9.02.  In such case, the amendment or waiver shall
bind each holder of a Convertible Subordinated Note who has consented to it.

SECTION 9.05      NOTATION ON OR EXCHANGE OF CONVERTIBLE SUBORDINATED NOTES.

      Convertible Subordinated Notes authenticated and delivered after the
execution of any supplemental indenture pursuant to this Article 9 may, and
shall if required by the Trustee, bear a notation in the form approved by the
Trustee as to any matter provided for in such supplemental indenture.  If the
Company shall so determine, new Convertible Subordinated Notes so modified as to
conform, in the opinion of the Company and the Trustee, to any such supplemental
indenture may be prepared and executed by the Company and authenticated and
delivered by the Trustee in exchange for outstanding Convertible Subordinated
Notes.

SECTION 9.06      TRUSTEE PROTECTED.

      The Trustee shall sign any amendment or supplemental indenture authorized
pursuant to this Article 9 if such amendment or supplemental indenture does not
adversely affect the rights, duties, liabilities or immunities of the Trustee.
If it does, the Trustee may, but need not, sign it.  In signing such amendment
or supplemental indenture, the Trustee shall be entitled to receive, and shall
be fully protected in relying upon, an Officers' Certificate and an Opinion of
Counsel as conclusive evidence that such amendment or supplemental indenture is
authorized or permitted by this Indenture, that it is not inconsistent herewith,
and that it will be valid and binding upon the Company in accordance with its
terms.

duties imposed by TIA Section 318(c), such imposed duties shall control. If

of the TIA that may be so modified or excluded, the latter provision shall be
deemed to apply to this Indenture as so modified or to be excluded, as the
case may be.

institutions in the City of New York or the City of San Jose, California are
not required to be open, and a "business day" is any day that is not a Legal

may be made at that place on the next succeeding day that is not a Legal
Holiday, and no interest shall accrue for the intervening period.  If any

                                SUBORDINATION

SECTION 11.01     AGREEMENT TO SUBORDINATE.

            The Company agrees, and each holder of Convertible Subordinated
Notes by accepting a Convertible Subordinated Note agrees, that the indebtedness
evidenced by the Convertible Subordinated Note is subordinated in right of
payment, to the extent and in the manner provided in this Article 11, to the
prior payment in full of all Senior Debt (whether outstanding on the date hereof
or hereafter created, incurred, assumed or guaranteed), and that the
subordination is for the benefit of the holders of Senior Debt.

SECTION 11.02     LIQUIDATION; DISSOLUTION; BANKRUPTCY.

            Upon any distribution to creditors of the Company in a liquidation

receivership or similar proceeding relating to the Company or its property, in
an assignment for the benefit of creditors or any marshalling of the Company's
assets and liabilities:

   
            (1)   holders of Senior Debt shall be entitled to receive payment in
      full of all Obligations due in respect of such Senior Debt (including
      interest after the commencement of any such proceeding at the rate
      specified in the applicable Senior Debt) in cash or U.S. Government
      Obligations or other payment satisfactory to the holders of the Senior
      Debt before holders of Convertible Subordinated Notes shall be entitled to
      receive any payment with respect to the Convertible Subordinated Notes

      (i) securities that are subordinated to at least the same extent as the
      Convertible Subordinated Notes to (a) Senior Debt and (b) any securities
      issued in exchange for Senior Debt and (ii) payments and other
      distributions made from any trust created pursuant to Section 8.01
      hereof); and
    

   
            (2)   until all Senior Debt is paid in full in cash or U.S.
      Government Obligations or other payment satisfactory to the holders
      of the Senior Debt, any distribution to which holders of Convertible
      Subordinated Notes would be entitled but for this Article 11 shall be
      made to holders of Senior Debt (except that holders of Convertible
      Subordinated Notes may receive securities that are subordinated to at
      least the same extent as the
    

                                        44
<PAGE>



      Convertible Subordinated Notes to (a) Senior Debt and (b) any securities
      issued in exchange for Senior Debt), as their interests may appear.

SECTION 11.03     DEFAULT ON SENIOR DEBT AND/OR DESIGNATED SENIOR DEBT.

   
            The Company may not make any payment or distribution to the Trustee
or any holder of Convertible Subordinated Notes in respect of Obligations with
respect to the Convertible Subordinated Notes and may not acquire from the
Trustee or any holder of Convertible Subordinated Notes any Convertible
Subordinated Notes (other than, in each case, (i) securities that are
subordinated to at least the same extent as the Convertible Subordinated Notes
to (a) Senior Debt and (b) any securities issued in exchange for Senior Debt and
(ii) payments and other distributions made from any trust created pursuant to
Section 8.01 hereof) until all Senior Debt has been paid in full in cash or
U.S. Government Obligations or other payment satisfactory to the holders of
Senior Debt if:
    

            (i)   a default in the payment of any principal of, premium, if any,
      interest, rent or other Obligations in respect of Senior Debt occurs and
      is continuing beyond any applicable grace period in the agreement,
      indenture or other document governing such Senior Debt; or

   
            (ii)  a default, other than a payment default, on Designated Senior
      Debt occurs and is continuing that then permits holders of such Designated
      Senior Debt to accelerate its maturity and the Trustee receives a notice
      of the default (a "Payment Blockage Notice") from a person who may give it
      pursuant to Section 11.11 hereof.
    

   
                  If the Trustee receives any Payment Blockage Notice
      pursuant to Section 11.03 (ii) hereof, no subsequent Payment Blockage
      Notice shall be effective for purposes of such Section unless and until
      (i) at least 365 days shall have elapsed since the effectiveness of the
      immediately prior Payment Blockage Notice and (ii) all scheduled payments
      of principal, premium, if any, and interest on the Convertible
      Subordinated Notes that have come due have been paid in full in cash.
      No nonpayment default that existed or was continuing on the date of
      delivery of any Payment Blockage Notice to the Trustee shall be, or be
      made, the basis for a subsequent Payment Blockage Notice.

respect of the Convertible Subordinated Notes and may acquire them upon the
earlier of:

            (1)   the date upon which the default is cured or waived, or

            (2)   in the case of a default referred to in Section 11.03(ii)
      hereof, 179 days pass after notice is received if the maturity of such
      Designated Senior Debt has not been accelerated,

if this Article otherwise permits the payment, distribution or acquisition at
the time of such payment or acquisition.

SECTION 11.04     ACCELERATION OF CONVERTIBLE SUBORDINATED NOTES

   
            In the event of the acceleration of the Convertible Subordinated
Notes because of an Event of Default, the Company may not make any payment or
distribution to the Trustee or any holder of Convertible Subordinated Notes
in respect of Obligations with respect to Convertible Subordinated Notes and
may not acquire or purchase from the Trustee or any holder of any Convertible
Subordinated Notes (other than, in each case, (i) securities that are
subordinated to at least the same extent as the Convertible Subordinated
Notes to (a) Senior Debt and (b) any securities issued in exchange for Senior
Debt, and (ii) payments and other distributions made from any trust created
pursuant to Section 8.01 until all Senior Debt has been paid in full in cash
or U.S. Government Obligations or other payment satisfactory to the holders
of the Senior Debt or such acceleration is rescinded in accordance with the
terms of this Indenture. If payment of the Convertible Subordinated Notes is
accelerated because of an Event of Default, the Company shall promptly notify
holders of Senior Debt of the acceleration.
    

SECTION 11.05     WHEN DISTRIBUTION MUST BE PAID OVER.

   
            In the event that the Trustee or any holder of Convertible
Subordinated Notes receives any payment or any distributions of assets of
the Company of any kind with respect to the Convertible Subordinated Notes,
whether in cash, property or securities, including without limitation by way
of set-off or otherwise, at a time when payment or distribution is prohibited
by this Indenture, such payment shall be held by the Trustee or such holder,
in trust for the benefit of, and shall be paid forthwith over and delivered,
to the extent necessary to make payment in full of any Senior Debt remaining
unpaid, after giving effect to any concurrent payment or distribution to or
for the holders of Senior Debt; provided that the foregoing shall apply
to the Trustee only if the Trustee has actual knowledge (as determined in
accordance with Section 11.11) that such payment or distribution is
prohibited by this Indenture.
    

            With respect to the holders of Senior Debt, the Trustee undertakes
to perform only such obligations on the part of the Trustee as are specifically
set forth in this Article 11, and no implied covenants or obligations with
respect to the holders of Senior Debt shall be read into this Indenture against
the Trustee.  The Trustee shall not be deemed to owe any fiduciary duty to the
holders of Senior Debt, and shall not be liable to any such holders if the
Trustee shall pay over or distribute to or on behalf of holders of Convertible
Subordinated Notes or the Company or any other person money or assets to which
any holders of Senior Debt shall be entitled by virtue of this Article 11,
except if such payment is made as a result of the willful misconduct or gross
negligence of the Trustee.

SECTION 11.06     NOTICE BY COMPANY.

   
            The Company shall promptly notify the Trustee of any facts known
to the Company that would cause a payment of any Obligations with respect to
the Convertible Subordinated Notes or to the purchase of any Convertible
Subordinated Notes by the Company to violate this Article, but failure to
give such notice shall not affect the subordination of the Convertible
Subordinated Notes to the Senior Debt as provided in this Article.
    

SECTION 11.07     SUBROGATION.

            After all Senior Debt is paid in full and until the Convertible
Subordinated Notes are paid in full, holders of Convertible Subordinated Notes
shall be subrogated (equally and ratably with all other indebtedness pari passu
with the Convertible Subordinated Notes) to the rights of holders of Senior Debt
to receive distributions applicable to Senior Debt to the extent that
distributions otherwise payable to the holders of Convertible Subordinated Notes
have been applied to the payment of Senior Debt.  A distribution made under this
Article to holders of Senior Debt that otherwise would have been made to holders


                                        46
<PAGE>



of Convertible Subordinated Notes is not, as between the Company and holders of
Convertible Subordinated Notes, a payment by the Company on the Convertible
Subordinated Notes.

SECTION 11.08     RELATIVE RIGHTS.

            This Article defines the relative rights of holders of Convertible
Subordinated Notes and holders of Senior Debt.  Nothing in this Indenture shall:

            (1)   impair, as between the Company and holders of Convertible
      Subordinated Notes, the obligation of the Company, which is absolute and
      unconditional, to pay principal of and interest on the Convertible
      Subordinated Notes in accordance with their terms;

   
            (2)   affect the relative rights of holders of Convertible
      Subordinated Notes and creditors (other than with respect to Senior
      Debt) of the Company other than their rights in relation to holders of
      Senior Debt; or
    

            (3)   prevent the Trustee or any holder of Convertible Subordinated
      Notes from exercising its available remedies upon a Default or Event of
      Default, subject to the rights of holders and owners of Senior Debt to
      receive distributions and payments otherwise payable to holders of
      Convertible Subordinated Notes.

            If the Company fails because of this Article to pay principal of or
interest on a Convertible Subordinated Note on the due date, the failure is
still a Default or Event of Default.

SECTION 11.09     SUBORDINATION MAY NOT BE IMPAIRED BY COMPANY.

            No right of any holder of Senior Debt to enforce the subordination
of the indebtedness evidenced by the Convertible Subordinated Notes shall be
impaired by any act or failure to act by the Company or any holder of
Convertible Subordinated Notes or by the failure of the Company or any such
holder to comply with this Indenture.

SECTION 11.10     DISTRIBUTION OR NOTICE TO REPRESENTATIVE.

            Whenever a distribution is to be made or a notice given to holders
of Senior Debt, the distribution may be made and the notice given to their
Representative.

            Upon any payment or distribution of assets of the Company referred
to in this Article 11, the Trustee and the holders of Convertible Subordinated
Notes shall be entitled to rely upon any order or decree made by any court of
competent jurisdiction or upon any certificate of such Representative or of the
liquidating trustee or agent or other person making any distribution to the
Trustee or to the holders of Convertible Subordinated Notes


                                        47
<PAGE>



for the purpose of ascertaining the persons entitled to participate in such
distribution, the holders of the Senior Debt and other indebtedness of the
Company, the amount thereof or payable thereon, the amount or amounts paid or
distributed thereon and all other facts pertinent thereto or to this Article 11.

SECTION 11.11     RIGHTS OF TRUSTEE AND PAYING AGENT.

   

            Notwithstanding the provisions of this Article 11 or any other
provision of this Indenture, the Trustee shall not be charged with knowledge
of the existence of any facts that would prohibit the making of any payment
or distribution by the Trustee (other than pursuant to Section 11.04), and
the Trustee may continue to make payments on the Convertible Subordinated
Notes, unless the Trustee shall have received at least two business days
prior to the date of such payment or distribution written notice of facts
that would cause such payment or distribution with respect to the Convertible
Subordinated Notes to violate this Article.  Only the Company or a
Representative may give the notice.
    

   
            Nothing in this Article 11 shall impair the claims of, or
payments to, the Trustee under or pursuant to Section 7.07 hereof.
    

            The Trustee in its individual or any other capacity may hold Senior
Debt with the same rights it would have if it were not Trustee.  Any Agent may
do the same with like rights.

SECTION 11.12     AUTHORIZATION TO EFFECT SUBORDINATION.

            Each holder of a Convertible Subordinated Note by the holder's
acceptance thereof authorizes and directs the Trustee on the holder's behalf to
take such action as may be necessary or appropriate to effectuate the
subordination as provided in this Article 11, and appoints the Trustee to act as
the holder's attorney-in-fact for any and all such purposes.  If the Trustee
does not file a proper proof of claim or proof of debt in the form required in
any proceeding referred to in Section 6.09 hereof at least 30 days before the
expiration of the time to file such claim, the holders of any Senior Debt or
their Representatives are hereby authorized to file an appropriate claim for and
on behalf of the holders of the Convertible Subordinated Notes.

   
SECTION 11.13     ARTICLE APPLICABLE TO PAYING AGENTS.
    

   
            In case at any time any Paying Agent other than the Trustee shall
have been appointed by the Company and be then acting hereunder, the term
"Trustee" as used in this Article shall in such case (unless the context
otherwise requires) be construed as extending to and including such Paying
Agent within its meaning as fully for all intents and purposes as if such
Paying Agent were named in this Article in addition to or in place of the
Trustee; PROVIDED, HOWEVER, that the second and third paragraphs of Section
11.11 shall not apply to the Company or any Affiliate of the Company if it or
such Affiliate acts as Paying Agent.
    

   
SECTION 11.14     SENIOR DEBT ENTITLED TO RELY.
    

   
            The holders of Senior Debt shall have the right to rely upon this
Article 11, and no amendment or modification of the provisions contained
herein shall diminish the rights of such holders unless such holders shall
have agreed in writing thereto.
    

                                  ARTICLE 12

                 CONVERSION OF CONVERTIBLE SUBORDINATED NOTES

SECTION 12.01     RIGHT TO CONVERT.

   
      Subject to and upon compliance with the provisions of this Indenture,
each holder of Convertible Subordinated Notes shall have the right, at his or
her option, at any time prior to the close of business on the last trading
day prior to the Maturity Date (except that, with respect to any Convertible
Subordinated Note or portion of a Convertible Subordinated
    
                                        48
<PAGE>


   

Note which is called for redemption, such right shall terminate, except as
provided in the fourth paragraph of Section 12.02, at the close of business
on the last trading day prior to the date fixed for redemption of such
Convertible Subordinated Note or portion of a Convertible Subordinated Note
unless the Company defaults in the payment due upon redemption thereof and
such right shall terminate with respect to any Convertible Subordinated Note
or portion thereof subject to a duly completed election for repurchase unless
the Company defaults in the payment due upon repurchase or such holder elects
to withdraw the submission of such election to repurchase on or prior to the
close of business on the Designated Event Offer Termination Date) to convert
the principal amount of any Convertible Subordinated Note held by such
holder, or any portion of such principal amount which is $1,000 or an
integral multiple thereof, into that number of fully paid and non-assessable
shares of Common Stock (as such shares shall then be constituted) obtained by
dividing the principal amount of the Convertible Subordinated Note or portion
thereof surrendered for conversion by the Conversion Price in effect at such
time, by surrender of the Convertible Subordinated Note so to be converted in
whole or in part in the manner provided in Section 12.02.  A holder of
Convertible Subordinated Notes is not entitled to any rights of a holder of
Common Stock until such holder of Convertible Subordinated Notes has
converted his or her Convertible Subordinated Notes to Common Stock, and only
to the extent such Convertible Subordinated Notes are deemed to have been
converted to Common Stock under this Article 12.
    

SECTION 12.02     EXERCISE OF CONVERSION PRIVILEGE; ISSUANCE OF
                  COMMON STOCK ON CONVERSION; NO ADJUSTMENT FOR
                  INTEREST OR DIVIDENDS.

      To exercise, in whole or in part, the conversion privilege with respect to
any Convertible Subordinated Note, the holder of such Convertible Subordinated
Note shall surrender such Convertible Subordinated Note, duly endorsed, at an
office or agency maintained by the Company pursuant to Section 4.04, accompanied
by the funds, if any, required by the penultimate paragraph of this Section
12.02, and shall give written notice of conversion in the form provided on the
Convertible Subordinated Notes (or such other notice which is acceptable to the
Company) to the office or agency that the holder of Convertible Subordinated
Notes elects to convert such Convertible Subordinated Note or such portion
thereof specified in said notice.  Such notice shall also state the name or
names (with address or addresses) in which the certificate or certificates for
shares of Common Stock which are issuable on such conversion shall be issued,
and shall be accompanied by transfer taxes, if required pursuant to Section
12.07.  Each such Convertible Subordinated Note surrendered for conversion
shall, unless the shares issuable on conversion are to be issued in the same
name as the registration of such Convertible Subordinated Note, be duly endorsed
by, or be accompanied by instruments of transfer in form satisfactory to the
Company duly executed by, the holder of Convertible Subordinated Notes or his or
her duly authorized attorney.

   
      As promptly as practicable after satisfaction of the requirements for
conversion set forth above
    

                                        49
<PAGE>


   
the Company shall issue and shall deliver to such holder at the office or
agency maintained by the Company for such purpose pursuant to Section 4.04, a
certificate or certificates for the number of full shares of Common Stock
issuable upon the conversion of such Convertible Subordinated Note or portion
thereof in accordance with the provisions of this Article 12 and a check or
cash in respect of any fractional interest in respect of a share of Common
Stock arising upon such conversion, as provided in Section 12.03 (which
payment, if any, shall be paid no later than five business days after
satisfaction of the requirements for conversion set forth above).  In case
any Convertible Subordinated Note of a denomination of an integral multiple
greater than $1,000 is surrendered for partial conversion, and subject to
Section 2.02, the Company shall execute, and the Trustee shall authenticate
and deliver to the holder of the Convertible Subordinated Note so
surrendered, without charge to him or her, a new Convertible Subordinated
Note or Convertible Subordinated Notes in authorized denominations in an
aggregate principal amount equal to the unconverted portion of the
surrendered Convertible Subordinated Note.
    

      Each conversion shall be deemed to have been effected as to any such
Convertible Subordinated Note (or portion thereof) on the date on which the
requirements set forth above in this Section 12.02 have been satisfied as to
such Convertible Subordinated Note (or portion thereof), and the person in whose
name any certificate or certificates for shares of Common Stock are issuable
upon such conversion shall be deemed to have become on said date the holder of
record of the shares represented thereby; PROVIDED, HOWEVER, that any such
surrender on any date when the Company's stock transfer books are closed shall
constitute the person in whose name the certificates are to be issued as the
record holder thereof for all purposes on the next succeeding day on which such
stock transfer books are open, but such conversion shall be at the Conversion
Price in effect on the date upon which such Convertible Subordinated Note is
surrendered.

      Any Convertible Subordinated Note or portion thereof surrendered for
conversion during the period from the close of business on the record date for
any interest payment through the close of business on the trading day next
preceding such interest payment date shall (unless such Convertible Subordinated
Note or portion thereof being converted has been called for redemption on a date
in such period) be accompanied by payment, in funds acceptable to the Company,
of an amount equal to the interest otherwise payable on such interest payment
date on the principal amount being converted; PROVIDED HOWEVER, that no such
payment need be made if there exists at the time of conversion a default in the
payment of interest on the Convertible Subordinated Notes.  An amount equal to
such payment shall be paid by the Company on such interest payment date to the
holder of such Convertible Subordinated Note at the close of business on such
record date; PROVIDED, HOWEVER, that if the Company defaults in the payment of
interest on such interest payment date, such amount shall be paid to the person
who made such required payment.  Except as provided above in this Section 12.02,
no adjustment shall be made for interest accrued on any Convertible Subordinated
Note converted or for dividends on any shares issued upon the conversion of such
Convertible Subordinated Note as provided in this Article 12.

SECTION 12.03     CASH PAYMENTS IN LIEU OF FRACTIONAL SHARES.

   
      No fractional shares of Common Stock or scrip representing fractional
shares shall be issued upon conversion of Convertible Subordinated Notes.  If
more than one Convertible Subordinated Note shall be surrendered for conversion
at one time by the same holder, the number of full shares which shall be
issuable upon conversion shall be computed on the basis of the aggregate
principal amount of the Convertible Subordinated Notes (or specified portions
thereof to the extent permitted hereby) so surrendered for conversion.  If any
fractional share of stock otherwise would be issuable upon the conversion of any
Convertible Subordinated Note or Convertible Subordinated Notes, the Company
shall make an adjustment therefor in cash based upon the Current Market Price
of the Common Stock on the last trading day of conversion.
    

SECTION 12.04     CONVERSION PRICE.

      The conversion price shall be as specified in the form of Convertible
Subordinated Note attached as Exhibit A hereto, subject to adjustment as
provided in this Article 12.

SECTION 12.05     ADJUSTMENT OF CONVERSION PRICE.

      The Conversion Price shall be adjusted from time to time by the Company as
follows:

            (a)   If the Company shall hereafter pay a dividend or make a
      distribution to all holders of the outstanding Common Stock in shares of
      Common Stock, the Conversion Price in effect at the opening of business on
      the date following the date fixed for the determination of stockholders
      entitled to receive such dividend or other distribution shall be reduced
      by multiplying such Conversion Price by a fraction of which the numerator
      shall be the number of shares of Common Stock outstanding at the close of
      business on the Record Date (as defined in Section 12.05(g)) fixed for
      such determination and the denominator shall be the sum of such number of
      shares and the total number of shares constituting such dividend or other
      distribution, such reduction to become effective immediately after the
      opening of business on the day following the Record Date.  If any dividend
      or distribution of the type described in this Section 12.05(a) is declared
      but not so paid or made, the Conversion Price shall again be adjusted to
      the Conversion Price which would then be in effect if such dividend or
      distribution had not been declared.

   
            (b)   If the Company shall issue rights or warrants to all holders
      of its outstanding shares of Common Stock entitling them to subscribe for
      or purchase shares of Common Stock at a price per share less than the
      Current Market Price (as defined in Section 12.05(g)) on the Record Date
      fixed for the determination of


                                        51
<PAGE>



      stockholders entitled to receive such rights or warrants, the Conversion
      Price shall be adjusted so that the same shall equal the price determined
      by multiplying the Conversion Price in effect at the opening of business
      on the date after such Record Date plus the number of shares which the
      aggregate offering price of the total number of shares so offered would
      purchase at such Current Market Price, and of which the denominator shall
      be the number of shares of Common Stock outstanding on the close of
      business on the Record Date by a fraction of which the numerator shall
      be the number of shares of Common Stock outstanding at the close of
      business on the Record Date plus the total number of additional shares of
      Common Stock so offered for subscription or purchase.  Such adjustment
      shall become effective immediately after the opening of business on the
      day following the Record Date fixed for determination of stockholders
      entitled to receive such rights or warrants.  To the extent that shares of
      Common Stock are not delivered pursuant to such rights or warrants, upon
      the expiration or termination of such rights or warrants the Conversion
      Price shall be readjusted to the Conversion Price shall again be adjusted
      to be the Conversion Price which would then be in effect had the
      adjustments made upon the issuance of such rights or warrants been made on
      the basis of delivery of only the number of shares of Common Stock
      actually delivered.  If such rights or warrants are not so issued, the
      Conversion Price shall again be adjusted to be the Conversion Price which
      would then be in effect if such date fixed for the determination of
      stockholders entitled to receive such rights or warrants had not been
      fixed.  In determining whether any rights or warrants entitle the holders
      to subscribe for or purchase shares of Common Stock at less than such
      Current Market Price, and in determining the aggregate offering price of
      such shares of Common Stock, there shall be taken into account any
      consideration received for such rights or warrants, with the value of such
      consideration, if other than cash, to be determined by the Board of
      Directors.
    
            (c)   If the outstanding shares of Common Stock shall be subdivided
      into a greater number of shares of Common Stock, the Conversion Price in
      effect at the opening of business on the day following the day upon which
      such subdivision becomes effective shall be proportionately reduced, and,
      conversely, if the outstanding shares of Common Stock shall be combined
      into a smaller number of shares of Common Stock, the Conversion Price in
      effect at the opening of business on the day following the day upon which
      such combination becomes effective shall be proportionately increased,
      such reduction or increase, as the case may be, to become effective
      immediately after the opening of business on the day following the day
      upon which such subdivision or combination becomes effective.

   
            (d)   If the Company shall, by dividend or otherwise, distribute to
      all holders of its Common Stock shares of any class of capital stock of
      the Company (other than any dividends or distributions to which Section
      12.05(a) applies) or evidences of its indebtedness, cash or other assets
      (including securities, but excluding any rights or warrants of a type
      referred to in Section 12.05(b) and dividends and distributions paid
      exclusively in cash and excluding any


                                        52
<PAGE>



      capital stock, evidences of indebtedness, cash or assets distributed upon
      a merger or consolidation to which Section 12.06 applies) (the foregoing
      hereinafter in this Section 12.05(d) called the "Securities")), then, in
      each such case, the Conversion Price shall be reduced so that the same
      shall be equal to the price determined by multiplying the Conversion Price
      in effect immediately prior to the close of business on the Record Date
      (as defined in Section 12.05(g)) with respect to such distribution by a
      fraction of which the numerator shall be the Current Market Price
      (determined as provided in Section 12.05(g)) on such date less the fair
      market value (as determined by the Board of Directors, whose determination
      shall be conclusive and described in a resolution of the Board of
      Directors) on such date of the portion of the Securities so distributed
      applicable to one share of Common Stock and the denominator shall be such
      Current Market Price, such reduction to become effective immediately prior
      to the opening of business on the day following the Record Date;
      PROVIDED, HOWEVER, that in the event the then fair market value (as so
      determined) of the portion of the Securities so distributed applicable to
      one share of Common Stock is equal to or greater than the Current Market
      Price on the Record Date, in lieu of the foregoing adjustment, adequate
      provision shall be made so that each holder of Convertible Subordinated
      Notes shall have the right to receive upon conversion of a Convertible
      Subordinated Note (or any portion thereof) the amount of Securities such
      holder would have received had such holder converted such Convertible
      Subordinated Note (or portion thereof) immediately prior to such Record
      Date.  If such dividend or distribution is not so paid or made, the
      Conversion Price shall again be adjusted to be the Conversion Price which
      would then be in effect if such dividend or distribution had not been
      declared.  If the Board of Directors determines the fair market value of
      any distribution for purposes of this Section 12.05(d) by reference to the
      actual or when issued trading market for any securities comprising all or
      part of such distribution, it must in doing so consider the prices in such
      market over the same period used in computing the Current Market Price
      pursuant to Section 12.05(g) to the extent possible.
    


                                        53

      Rights or warrants distributed by the Company to all holders of
Common Stock entitling the holders thereof to subscribe for or purchase
shares of the Company's capital stock (either initially or under certain
circumstances), which rights or warrants, until the occurrence of a specified
event or events ("Trigger Event"): (i) are deemed to be transferred with such
shares of Common Stock; (ii) are not exercisable; and (iii) are also issued
in respect of future issuances of Common Stock, shall be deemed not to have
been distributed for purposes of this Section 12.05(d) (and no adjustment to
the Conversion Price under this Section 12.05(d) shall be required) until the
occurrence of the earliest Trigger Event, whereupon such rights and warrants
shall be deemed to have been distributed and an appropriate adjustment to the
Conversion Price under this Section 12.05(d) shall be made. If any such
rights (including the Rights), or warrants, including any such existing
rights or warrants distributed prior to the date of this Indenture (including
the Rights), are subject to subsequent events, upon the occurrence of each of
which such rights or warrants shall become exercisable to purchase different
securities, evidences of indebtedness or other assets, then the occurrence of
each such event shall be deemed to be such date of issuance and record date
with respect to new rights or warrants (and a termination or expiration of
the existing rights or warrants without exercise by the holder thereof).  In
addition, in the event of any distribution (or deemed distribution) of rights
or warrants (including the Rights), or any Trigger Event with respect
thereto, that was counted for purposes of calculating a distribution amount
for which an adjustment to the Conversion Price under this Section 12.05 was
made, (1) in the case of any such rights (including the Rights) or warrants
which shall all have been redeemed or repurchased without exercise by any
holders thereof, the Conversion Price shall be readjusted upon such final
redemption or repurchase to give effect to such distribution or Trigger
Event, as the case may be, as though it were a cash distribution, equal to
the per share redemption or repurchase price received by a holder or holders
of Common Stock with respect to such rights or warrants (assuming such holder
had retained such rights or warrants), made to all holders of Common Stock as
of the date of such redemption or repurchase, and (2) in the case of such
rights or warrants (including the Rights) which shall have expired or been
terminated without exercise by any holders thereof, the Conversion Price
shall be readjusted as if such rights and warrants had not been issued. In
lieu of any adjustment to the Conversion Price otherwise required by this
Section 12.05(d) as a result of a Trigger Event affecting rights (the
"Rights") distributed pursuant to the Company's First Amended and Restated
Stockholder Rights Plan, as amended (the "Rights Plan"), the Company may
amend such Rights Plan to provide that upon conversion of the Convertible
Subordinated Notes the holder thereof will receive, in addition to the Common
Stock issuable upon such conversion, the Rights which attached to such shares
of Common Stock or would have attached to such shares if the Rights had not
become separated from the Common Stock pursuant to the provisions of the
Rights Plan.
    

   
      Notwithstanding any other provision of this Section 12.05(d) to the
contrary, rights, warrants, evidences of indebtedness, other securities, cash
or other assets (including, without limitation, any rights distributed
pursuant to any stockholder rights plan) shall be deemed not to have been
distributed for purposes of this Section 12.05(d) if the Company makes proper
provision so that each holder of Convertible Subordinated Notes who converts
a Convertible Subordinated Note or any portion thereof) after the date fixed
for determination of stockholders entitled to receive such distribution shall
be entitled to receive upon such conversion, in addition to the shares of
Common Stock issuable upon such conversion, the amount and kind of such
distributions that such holder would have been entitled to receive if such
holder had, immediately prior to such determination date, converted such
Convertible Subordinated Note into Common Stock.

      For purposes of this Section 12.05(d) and Sections 12.05(a) and (b), any
dividend or distribution to which this Section 12.05(d) is applicable that also
includes shares of Common Stock, or rights or warrants to subscribe for or
purchase shares of Common Stock to which Section 12.05(b) applies (or both),
shall be deemed instead to be (1) a dividend or distribution of the evidences of
indebtedness, assets, shares of capital stock, rights or warrants other than
such shares of Common Stock or rights or warrants to which Section 12.05(b)
applies (and any Conversion Price reduction required by this Section 12.05(d)
with respect to such dividend or distribution shall then be made) immediately
followed by (2) a dividend or distribution of such shares of Common Stock or
such rights or warrants (and any further Conversion Price reduction required by
Sections 12.05(a) and [(b) with respect to such dividend or distribution shall
then be made, except that (a) the Record Date of such dividend or distribution
shall be substituted as "the date fixed for the determination of stockholders
entitled to receive such dividend or other distribution", "Record Date fixed for
such determination" and "Record Date" within the meaning of Section 12.05(a) and
as "the date fixed for the determination of stockholders entitled to receive
such rights or warrants", "the Record Date fixed for the determination of the
stockholders entitled to receive such rights or warrants" and "such Record Date"
within the meaning of Section 12.05(b)] and (b) any shares of Common Stock
included in such dividend or distribution shall not be deemed "outstanding at
the close of business on the date fixed for such determination" within the
meaning of Section 12.05(a).

      (e)   If the Company shall, by dividend or otherwise, distribute to all
holders of its Common Stock cash (excluding any cash that is distributed upon a
merger or consolidation to which Section 12.06 applies or as part of a
distribution referred to in Section 12.05(d)) in an aggregate amount that,
combined together with (1) the aggregate amount of any other such distributions
to all holders of its Common Stock made exclusively in cash within the 12 months
preceding the date of payment of such distribution, and in respect of which no
adjustment pursuant to this Section 12.05(e) has been made, and (2) the
aggregate of any cash plus the fair market value as determined by the Board of
Directors, whose determination shall be conclusive and described in a resolution
of the Board of Directors) of consideration payable in respect of any tender
offer by the Company or any of its subsidiaries for all or any portion of the
Common Stock concluded within the 12 months preceding the date of payment of
such distribution, and in respect of which no adjustment pursuant to Section
12.05(f) has ben made, exceeds 15% of the product of the Current Market Price
(determined as provided in Section 12.05(g)) on the Record Date with respect to
such distribution times the number of shares of Common Stock outstanding on such
date, then, and in each such case, immediately after the close of business on
such date, the Conversion Price shall be reduced so that the same shall equal
the price determined by multiplying the Conversion Price in effect immediately
prior to the close of business on such Record Date by a fraction (i) the
numerator of which shall be equal to the Current Market Price on the Record Date
less an amount equal to the quotient of (x) the excess of such combined amount
over such 15% and (y) the number of shares of Common Stock outstanding on the
Record Date and (ii) the denominator of which shall be equal to the Current
Market Price on such Record Date; PROVIDED, HOWEVER, that if the portion of
the cash so distributed applicable to


                                        55
<PAGE>



one share of Common Stock is equal to or greater than the Current Market Price
of the Common Stock on the Record Date, in lieu of the foregoing adjustment,
adequate provision shall be made so that each holder of Convertible Subordinated
Notes shall have the right to receive upon conversion of a Convertible
Subordinated Note (or any portion thereof) the amount of cash such holder would
have received had such holder converted such Convertible Subordinated Note (or
portion thereof) immediately prior to such Record Date.  If such dividend or
distribution is not so paid or made, the Conversion Price shall again be
adjusted to be the Conversion Price which would then be in effect if such
dividend or distribution had not been declared.  Any cash distribution to all
holders of Common Stock as to which the Company makes the election permitted by
Section 12.05(m) and as to which the Company has complied with the requirements
of such Section shall be treated as not having been made for all purposes of
this Section 12.05(e).

      (f)   If a tender offer made by the Company or any of its subsidiaries for
all or any portion of the Common Stock expires and such tender offer (as amended
upon the expiration thereof) requires the payment to stockholders (based on the
acceptance (up to any maximum specified in the terms of the tender offer) of
Purchased Shares (as defined below)) of an aggregate consideration having a fair
market value (as determined by the Board of Directors, whose determination shall
be conclusive and described in a resolution of the Board of Directors) that,
combined together with (1) the aggregate of the cash plus the fair market value
(as determined by the Board of Directors, whose determination shall be
conclusive and described in a resolution of the Board of Directors), as of the
expiration of such tender offer, of consideration payable in respect of any
other tender offers, by the Company or any of its subsidiaries for all or any
portion of the Common Stock expiring within the 12 months preceding the
expiration of such tender offer and in respect of which no adjustment pursuant
to this Section 12.05(f) has been made and (2) the aggregate amount of any
distributions to all holders of the Common Stock made exclusively in cash within
12 months preceding the expiration of such tender offer and in respect of which
no adjustment pursuant to Section 12.05(e) has been made, exceeds 15% of the
product of the Current Market Price (determined as provided in Section 12.05(g))
as of the last time (the "Expiration Time") tenders could have been made
pursuant to such tender offer (as it may be amended) times the number of shares
of Common Stock outstanding (including any tendered shares) on the Expiration
Time, then, and in each such case, immediately prior to the opening of business
on the day after the date of the Expiration Time, the Conversion Price shall be
adjusted so that the same shall equal the price determined by multiplying the
Conversion Price in effect immediately prior to close of business on the date of
the Expiration Time by a fraction of which the numerator shall be the number of
shares of Common Stock outstanding (including any tendered shares) on the
Expiration Time multiplied by the Current Market Price of the Common Stock on
the trading day next succeeding the Expiration Time and the denominator shall be
the sum of (x) the fair market value (determined as aforesaid) of the aggregate
consideration payable to stockholders based on the acceptance (up to any maximum
specified in the terms of the tender offer) of all shares validly tendered and
not withdrawn as of the Expiration Time (the shares deemed so accepted, up to
any such maximum, being referred to as the "Purchased Shares") and (y) the
product of the number of shares of Common Stock


                                        56
<PAGE>



outstanding (less any Purchased Shares) on the Expiration Time and the Current
Market Price of the Common Stock on the Trading Day next succeeding the
Expiration Time, such reduction (if any) to become effective immediately prior
to the opening of business on the day following the Expiration Time.  If the
Company is obligated to purchase shares pursuant to any such tender offer, but
the Company is permanently prevented by applicable law from effecting any such
purchases or all such purchases are rescinded, the Conversion Price shall again
be adjusted to be the Conversion Price which would then be in effect if such
tender offer had not been made.  If the application of this Section 12.05(f) to
any tender offer would result in an increase in the Conversion Price, no
adjustment shall be made for such tender offer under this Section 12.05(f).

      (g)   For purposes of this Section 12.05, the following terms shall have
the meaning indicated:

            (1)   "closing price" with respect to any securities on any day
      means the closing price on such day or, if no such sale takes place on
      such day, or, if no such sale takes place on such day, the average of the
      reported high and low prices on such day, in each case on The Nasdaq Stock
      Market or New York Stock Exchange, as applicable, or, if such security is
      not listed or admitted to trading on such national market or exchange, on
      the principal national securities exchange or quotation system on which
      such security is quoted or listed or admitted to trading, or, if not
      quoted or listed or admitted to trading on any national securities
      exchange or quotation system, the average of the high and low prices of
      such security on the over-the-counter market on the day in question as
      reported by the National Quotation Bureau Incorporated, or a similar
      generally accepted reporting service, or, if not so available, in such
      manner as furnished by any New York Stock Exchange member firm selected
      from time to time by the Board of Directors for that purpose, or a price
      determined in good faith by the Board of Directors, whose determination
      shall be conclusive and described in a resolution of the Board of
      Directors.

            (2)   "Current Market Price" means the average of the daily closing
      prices per share of Common Stock for the 10 consecutive trading days
      immediately prior to the date in question; PROVIDED, HOWEVER, that (1)
      if the "ex" date (as hereinafter defined) for any event (other than the
      issuance or distribution requiring such computation) that requires an
      adjustment to the Conversion Price pursuant to Sections 12.05(a), (b),
      (c), (d), (e) or (f) occurs during such 10 consecutive trading days, the
      closing price for each trading day prior to the "ex" date for such other
      event shall be adjusted by multiplying such closing price by the same
      fraction by which the Conversion Price is so required to be adjusted as a
      result of such other event, (2) if the "ex" date for any event (other than
      the issuance or distribution requiring such computation) that requires an
      adjustment to the Conversion Price pursuant to Section 12.05(a), (b), (c),
      (d), (e) or (f) occurs on or after the "ex" date for the issuance or
      distribution requiring such computation and prior to the day in question,
      the closing price for each trading day on and after the "ex" date for such
      other event shall be


                                        57
<PAGE>



      adjusted by multiplying such closing price by the reciprocal of the
      fraction by which the Conversion Price is so required to be adjusted as a
      result of such other event, and (3) if the "ex" date for the issuance or
      distribution requiring such computation is prior to the day in question,
      after taking into account any adjustment required pursuant to clause (1)
      or (2) of this proviso, the closing price for each trading day on or after
      such "ex" date shall be adjusted by adding thereto the amount of any cash
      and the fair market value (as determined by the Board of Directors in a
      manner consistent with any determination of such value for purposes of
      Sections 12.05(d) or (f), whose determination shall be conclusive and
      described in a resolution of the Board of Directors) of the evidences of
      indebtedness, shares of capital stock or assets being distributed
      applicable to one share of Common Stock as of the close of business on the
      day before such "ex" date.  For purposes of any computation under Section
      12.05(f), the Current Market Price on any date shall be deemed to be the
      average of the daily closing prices per share of Common Stock for such day
      and the next two succeeding trading days; PROVIDED, HOWEVER, that if the
      "ex" date for any event (other than the tender offer requiring such
      computation) that requires an adjustment to the Conversion Price pursuant
      to Section 12.05(a), (b), (c), (d), (e) or (f) occurs on or after the
      Expiration Time for the tender or exchange offer requiring such
      computation and prior to the day in question, the closing price for each
      trading day on and after the "ex" date for such other event shall be
      adjusted by multiplying such Closing Price by the reciprocal of the
      fraction by which the Conversion Price is so required to be adjusted as a
      result of such other event.  For purposes of this paragraph, the term "ex"
      date, (1) when used with respect to any issuance or distribution, means
      the first date on which the Common Stock trades regular way on the
      relevant exchange or in the relevant market from which the closing price
      was obtained without the right to receive such issuance or distribution,
      (2) when used with respect to any subdivision or combination of shares of
      Common Stock, means the first date on which the Common Stock trades
      regular way on such exchange or in such market after the time at which
      such subdivision or combination becomes effective, and (3) when used with
      respect to any tender or exchange offer means the first date on which the
      Common Stock trades regular way on such exchange or in such market after
      the Expiration Time of such offer.  Notwithstanding the foregoing,
      whenever successive adjustments to the Conversion Price are called for
      pursuant to this Section 12.05, such adjustments shall be made to the
      Current Market Price as may be necessary or appropriate to effectuate the
      intent of this Section 12.05 and to avoid unjust or inequitable results as
      determined in good faith by the Board of Directors.

            (3)   "fair market value" shall mean the amount which a willing
      buyer would pay a willing seller in an arm's length transaction.

            (4)   "Record Date" shall mean, with respect to any dividend,
      distribution or other transaction or event in which the holders of Common
      Stock have the right to receive any cash, securities or other property or
      in which the Common Stock (or other applicable security) is exchanged for
      or converted into any combination of cash,


                                        58
<PAGE>



      securities or other property, the date fixed for determination of
      stockholders entitled to receive such cash, securities or other property
      (whether such date is fixed by the Board of Directors or by statute,
      contract or otherwise).

            (5)   "trading day" shall mean (x) if the applicable security is
      listed or admitted for trading on the New York Stock Exchange or another
      national securities exchange, a day on which the New York Stock Exchange
      or another national securities exchange is open for business or (y) if the
      applicable security is quoted on The Nasdaq Stock Market, a day on which
      trades may be made thereon or (z) if the applicable security is not so
      listed, admitted for trading or quoted, any day other than a Saturday or
      Sunday or a day on which banking institutions in the State of New York are
      authorized or obligated by law or executive order to close.

      (h)   The Company may make such reductions in the Conversion Price, in
addition to those required by Sections 12.05(a), (b), (c), (d), (e) and (f), as
the Board of Directors considers to be advisable to avoid or diminish any income
tax to holders of Common Stock or rights to purchase Common Stock resulting from
any dividend or distribution of stock (or rights to acquire stock) or from any
event treated as such for income tax purposes.

      To the extent permitted by applicable law, the Company from time to time
may reduce the Conversion Price by any amount for any period of time if the
period is at least 20 days, the reduction is irrevocable during the period and
the Board of Directors has made a determination that such reduction would be in
the Company's best interests, which determination shall be conclusive and
described in a resolution of the Board of Directors.  Whenever the Conversion
Price is reduced pursuant to the preceding sentence, the Company shall mail to
the holders of Convertible Subordinated Note at his or her last address
appearing on the register of holders maintained for that purpose a notice of the
reduction at least 15 days prior to the date the reduced Conversion Price takes
effect, and such notice shall state the reduced Conversion Price and the period
during which it will be in effect.

      (i)   No adjustment in the Conversion Price shall be required unless such
adjustment would require an increase or decrease of at least 1% in such price;
PROVIDED, HOWEVER, that any adjustments which by reason of this Section
12.05(i) are not required to be made shall be carried forward and taken into
account in any subsequent adjustment.  All calculations under this Article 12
shall be made by the Company and shall be made to the nearest cent or to the
nearest one hundredth of a share, as the case may be.

      No adjustment need be made for a change in the par value or no par value
of the Common Stock.

      (j)   Whenever the Conversion Price is adjusted as herein provided, the
Company shall promptly file with the Trustee and any Conversion Agent other than
the Trustee an Officers' Certificate setting forth the Conversion Price after
such adjustment and setting forth a brief statement of the facts requiring such
adjustment.  Promptly after delivery of such


                                        59
<PAGE>



certificate, the Company shall prepare a notice of such adjustment of the
Conversion Price setting forth the adjusted Conversion Price and the date on
which each adjustment becomes effective and shall mail such notice of such
adjustment of the Conversion Price to each holder of Convertible Subordinated
Notes at his or her last address appearing on the register of holders maintained
for that purpose within 20 days of the effective date of such adjustment.
Failure to deliver such notice shall not affect the legality or validity of any
such adjustment.

      (k)   In any case in which this Section 12.05 provides that an adjustment
shall become effective immediately after a Record Date for an event, the Company
may defer until the occurrence of such event issuing to the holder of any
Convertible Subordinated Note converted after such Record Date and before the
occurrence of such event the additional shares of Common Stock issuable upon
such conversion by reason of the adjustment required by such event over and
above the Common Stock issuable upon such conversion before giving effect to
such adjustment.

      (l)   For purposes of this Section 12.05, the number of shares of Common
Stock at any time outstanding shall not include shares held in the treasury of
the Company but shall include shares issuable in respect of scrip certificates
issued in lieu of fractions of shares of Common Stock.  The Company shall not
pay any dividend or make any distribution on shares of Common Stock held in the
treasury of the Company.

      (m)   In lieu of making any adjustment to the Conversion Price pursuant to
Section 12.05(e), the Company may elect to reserve an amount of cash for
distribution to the holders of Convertible Subordinated Notes upon the
conversion of the Convertible Subordinated Notes so that any such holder
converting Convertible Subordinated Notes  will receive upon such conversion, in
addition to the shares of Common Stock and other items to which such holder is
entitled, the full amount of cash which such holder would have received if such
holder had, immediately prior to the Record Date for such distribution of cash,
converted its Convertible Subordinated Notes  into Common Stock, together with
any interest accrued with respect to such amount, in accordance with this
Section 12.05(m).  The Company may make such election by providing an Officers'
Certificate to the Trustee to such effect on or prior to the payment date for
any such distribution and depositing with the Trustee on or prior to such date
an amount of cash equal to the aggregate amount that the holders of Convertible
Subordinated Notes would have received if such holders had, immediately prior to
the Record Date for such distribution, converted all of the Convertible
Subordinated Notes into Common Stock.  Any such funds so deposited by the
Company with the Trustee shall be invested by the Trustee in U.S. Government
Obligations with a maturity not more than three (3) months from the date of
issuance.  Upon conversion of Convertible Subordinated Notes by a holder
thereof, such holder shall be entitled to receive, in addition to the Common
Stock issuable upon conversion, an amount of cash equal to the amount such
holder would have received if such holder had, immediately prior to the Record
Date for such distribution, converted its Convertible Subordinated Note into
Common Stock, along with such holder's pro-rata share of any accrued interest
earned as a consequence of the investment of such


                                        60
<PAGE>



funds.  Promptly after making an election pursuant to this Section 12.05(m), the
Company shall give or shall cause to be given notice to all holders of
Convertible Subordinated Notes of such election, which notice shall state the
amount of cash per $1,000 principal amount of Convertible Subordinated Notes
such holders shall be entitled to receive (excluding interest) upon conversion
of the Convertible Subordinated Notes as a consequence of the Company having
made such election.

SECTION 12.06     EFFECT OF RECLASSIFICATION, CONSOLIDATION, MERGER OR SALE.

      If any of the following events occur: (i) any reclassification or change
of the outstanding shares of Common Stock (other than a change in par value, or
from par value to no par value, or from no par value to par value, or as a
result of a subdivision or combination), (ii) any consolidation, merger or
combination of the Company with another corporation as a result of which holders
of Common Stock shall be entitled to receive stock, securities or other property
or assets (including cash) with respect to or in exchange for such Common Stock,
or (iii) any sale or conveyance of the properties and assets of the Company as,
or substantially as, an entirety to any other corporation as a result of which
holders of Common Stock shall be entitled to receive stock, securities or other
property or assets (including cash) with respect to or in exchange for such
Common Stock, then the Company or the successor or purchasing corporation, as
the case may be, shall execute with the Trustee a supplemental indenture (which
shall comply with the TIA as in force at the date of execution of such
supplemental indenture if such supplemental indenture is then required to so
comply) providing that the Convertible Subordinated Notes shall be convertible
into the kind and amount of shares of stock and other securities or property or
assets (including cash) receivable upon such reclassification, change,
consolidation, merger, combination, sale or conveyance by a holder of a number
of shares of Common Stock issuable upon conversion of the Convertible
Subordinated Notes  (assuming, for such purposes, a sufficient number of
authorized shares of Common Stock available to convert all such Convertible
Subordinated Notes) immediately prior to such reclassification, change,
consolidation, merger, combination, sale or conveyance assuming such holder of
Common Stock did not exercise his or her rights of election, if any, as to the
kind or amount of securities, cash or other property receivable upon such
consolidation, merger, statutory exchange, sale or conveyance (provided that, if
the kind or amount of securities, cash or other property receivable upon such
consolidation, merger, statutory exchange, sale or conveyance is not the same
for each share of Common Stock in respect of which such rights of election have
not been exercised ("non-electing share"), then, for the purposes of this
Section 12.06, the kind and amount of securities, cash or other property
receivable upon such consolidation, merger, statutory exchange, sale or
conveyance for each non-electing share shall be deemed to be the kind and amount
so receivable per share by a plurality of the non-electing shares).  Such
supplemental indenture shall provide for adjustments which shall be as nearly
equivalent as may be practicable to the adjustments provided for in this Article
12.  If, in the case of any such reclassification, change, consolidation,
merger, combination, sale or conveyance, the stock or other securities and
assets receivable thereupon by a holder of shares of Common Stock includes
shares of stock or other securities and assets of a corporation other than the


                                        61
<PAGE>



successor or purchasing corporation, as the case may be, in such
reclassification, change, consolidation, merger, combination, sale or
conveyance, then such supplemental indenture shall also be executed by such
other corporation and shall contain such additional provisions to protect the
interests of the holders of the Convertible Subordinated Notes as the Board of
Directors shall reasonably consider necessary by reason of the foregoing.

      The Company shall cause notice of the execution of such supplemental
indenture to be mailed to each holder of Convertible Subordinated Notes at his
or her address appearing on the register of holders for that purpose within 20
days after execution thereof.  Failure to deliver such notice shall not affect
the legality or validity of such supplemental indenture.

      The above provisions of this Section 12.06 shall similarly apply to
successive reclassifications, changes, consolidations, mergers, combinations,
sales and conveyances.

      If this Section 12.06 applies to any event or occurrence, Section 12.05
shall not apply.

SECTION 12.07     TAXES ON SHARES ISSUED.

      The issue of stock certificates on conversions of Convertible Subordinated
Notes shall be made without charge to the converting holder for any tax in
respect of the issue thereof.  The Company shall not, however, be required to
pay any tax which may be payable in respect of any transfer involved in the
issue and delivery of stock in any name other than that of the holder of any
Convertible Subordinated Note converted, and the Company shall not be required
to issue or deliver any such stock certificate unless and until the person or
persons requesting the issue thereof shall have paid to the Company the amount
of such tax or shall have established to the satisfaction of the Company that
such tax has been paid.

SECTION 12.08     RESERVATION OF SHARES; SHARES TO BE FULLY PAID;
                  LISTING OF COMMON STOCK.

      The Company shall provide, free from preemptive rights, out of its
authorized by unissued shares or sharers held in treasury, sufficient shares to
provide for the conversion of the Convertible Subordinated Notes from time to
time as such Convertible Subordinated Notes are presented for conversion.

      Before taking any action which would cause an adjustment reducing the
Conversion Price below the then par value, if any, of the shares of Common Stock
issuable upon conversion of the Convertible Subordinated Notes, the Company
shall take all corporate action which may, in the opinion of its counsel, be
necessary in order that the Company may validly and legally issue shares of such
Common Stock at such adjusted Conversion Price.



                                        62
<PAGE>



      The Company covenants that all shares of Common Stock issued upon
conversion of Convertible Subordinated Notes will be fully paid and
non-assessable by the Company and free from all taxes, liens and charges with
respect to the issue thereof.

      The Company further covenants that as long as the Common Stock is quoted
on the Nasdaq National market, or its successor, or all Common Stock issuable
upon conversion of the Convertible Subordinated Notes shall be eligible for such
quotation and if at any time the Common Stock is listed on the New York Stock
Exchange or any other national securities exchange, list and keep listed, all
Common Stock issuable upon conversion of the Convertible Subordinated Notes.

SECTION 12.09     RESPONSIBILITY OF TRUSTEE.

      The Trustee shall not at any time be under any duty of responsibility to
any holders of Convertible Subordinated Notes to determine whether any facts
exist which may require any adjustment of the Conversion Price, or with respect
to the nature or extent or calculation of any such adjustment when made, or with
respect to the method employed, or herein or in any supplemental indenture
provided to be employed, in making the same.  The Trustee shall not be
accountable with respect to the validity or value (or the kind or amount) of any
shares of Common Stock, or of any securities or property, which may at any time
be issued or delivered upon the conversion of any Convertible Subordinated Note;
and the Trustee makes no representations with respect thereto.  Subject to the
provisions of Section 7.01, the Trustee shall not be responsible for any failure
of the Company to issue, transfer or deliver any shares of Common Stock or stock
certificates or other securities or property or cash upon the surrender of any
Convertible Subordinated Note for the purpose of conversion or to comply with
any of the duties, responsibilities or covenants of the Company contained in
this Article 12.  Without limiting the generality of the foregoing, the Trustee
shall not have any responsibility to determine the correctness of any provisions
contained in any supplemental indenture entered into pursuant to Section 12.06
relating either to the kind or amount of shares of stock or securities or
property (including cash) receivable by holders of Convertible Subordinated
Notes upon the conversion of their Convertible Subordinated Notes after any
event referred to in such Section 12.06 or to any adjustment to be made with
respect thereto, but, subject to the provisions of Section 7.01, may accept as
conclusive evidence of the correctness of any such provisions, and shall be
protected in relying upon, the Officers' Certificate (which the Company shall be
obligated to file with the Trustee prior to the execution of any such
supplemental indenture) with respect thereto.

SECTION 12.10     NOTICE TO HOLDERS PRIOR TO CERTAIN ACTIONS.

      If

            (a)   the Company declares a dividend (or any other distribution) on
      its Common Stock (other than in cash out of retained earnings or other
      than a dividend


                                        63
<PAGE>



      that results in an adjustment in the Conversion Price pursuant to Section
      12.05 as to which the Company has made an election in accordance with
      Section 12.05(m)); or

            (b)   the Company authorizes the granting to the holders of its
      Common Stock of rights or warrants to subscribe for or purchase any share
      of any class of Common Stock or any other rights or warrants; or

            (c)   there is any reclassification of the Common Stock (other than
      a subdivision or combination of outstanding Common Stock, or a change in
      par value, or from par value to no par value, or from no par value to par
      value), or of any consolidation or merger to which the Company is a party
      and for which approval of any stockholders of the Company is required, or
      of the sale or transfer of all or substantially all of the assets of the
      Company; or

            (d)   there is any voluntary or involuntary dissolution, liquidation
      or winding-up of the Company;

then the Company shall cause to be filed with the Trustee and to be mailed to
each holder of Convertible Subordinated Notes at his or her address appearing on
the register maintained for that purpose as promptly as possible but in any
event at least 15 days prior to the applicable date hereinafter specified, a
notice stating (x) the date on which a record is to be taken for the purpose of
such dividend, distribution or rights or warrants, or, if a record is not to be
taken, the date as of which the holders of Common Stock of record to be entitled
to such dividend, distribution or rights are to be determined, or (y) the date
on which such reclassification, consolidation, merger, sale, transfer,
dissolution, liquidation or winding-up is expected to become effective or occur,
and the date as of which it is expected that holders of Common Stock of record
shall be entitled to exchange their Common Stock for securities or other
property deliverable upon such reclassification, consolidation, merger, sale,
transfer, dissolution, liquidation or winding-up.  Failure to give such notice,
or any defect therein, shall not affect the legality or validity of such
dividend, distribution, reclassification, consolidation, merger, sale, transfer,
dissolution, liquidation or winding-up.

      1.    INTEREST.  VLSI Technology, Inc., a Delaware corporation (the
"Company"), promises to pay interest on the principal amount of this
Convertible Subordinated Note at the rate per annum shown above.  The Company
will pay interest semiannually on April 1 and October 1 of each year.
Interest on the Convertible Subordinated Notes will accrue from the most

year composed of twelve 30-day months.
    

   
      2.    METHOD OF PAYMENT.  The Company will pay interest on the
Convertible Subordinated Notes (except defaulted interest) to the person in
whose name each Convertible Subordinated Note is registered at the close of
business on the March 15 or September 15 immediately preceding the relevant
interest payment date (each a "Regular Record Date") (other than with respect
to a Convertible Subordinated Note or portion thereof called for redemption
on a redemption date, or repurchased in connection with a Designated Event on
a repurchase date, during the period from the close of business on a Regular
Record Date to (but excluding) the next succeeding interest payment date (in
which case accrued interest shall be payable (unless such Convertible
Subordinated Note is converted) to the holder of the Convertible Subordinated
Note or portion thereof redeemed or repurchased in accordance with the
applicable redemption or repurchase provisions of the Indenture). Holder must

principal payments.  The Company will pay principal and interest in money of

public and private debts.  However, the Company may pay principal and
interest by check payable in such money, and may mail such check to the
holder's registered address.
    

   
      3.    PAYING AGENT AND REGISTRAR.  Harris Trust and Savings Bank
(together with any successor Trustee under the Indenture referred to below,
the "Trustee"), will act as Paying Agent and Registrar.  The Company may

Subject to certain limitations in the Indenture, the Company or any of its
subsidiaries may act in any such capacity.
    

   
      4.    INDENTURE.  The Company issued the Convertible Subordinated Notes
under an Indenture dated as of September ___, 1995 (the "Indenture") between
the Company and the Trustee.  The terms of the Convertible Subordinated Notes
include those stated in the Indenture and those made part of the Indenture by
reference to the Trust Indenture Act of 1939 (15 U.S. Code Sections
77aaa-77bbbb as in effect on the date of the Indenture (the "TIA").  The

terms, certain of which are summarized hereon, and holders are referred to
the Indenture and the TIA for a

                                        A-2
<PAGE>



statement of such terms.  The Convertible Subordinated Notes are unsecured
general obligations of the Company limited to (except as otherwise provided in
the Indenture) up to $150,000,000 in aggregate principal amount, unless an
election has been made as set forth in Article 2 of the Indenture to increase
such aggregate principal amount by an amount not to exceed $22,500,000.
Capitalized terms not defined below have the same meaning as is given to them in
the Indenture.
    

   
      5.    OPTIONAL REDEMPTION.  The Company shall not have the option to
redeem the Convertible Subordinated Notes prior to October 3, 1997.

Subordinated Notes, in whole or from time to time in part, at the following
redemption prices (expressed as percentages of principal amount), plus
accrued and unpaid interest to, but excluding, the date fixed for redemption

indicated (October 3 with respect to 1997); provided, however, that the
Company shall not have the option to redeem the Convertible Subordinated
Notes prior to October 3, 1999 unless the closing price of the Common Stock
on the principal stock exchange or market on which the Common Stock is then
listed or admitted to trading equals or exceeds 125% of the Conversion Price

ending on the fifth trading day prior to the date the notice of redemption is
first mailed to the holders of the Convertible Subordinated Notes:

      6.    NOTICE OF REDEMPTION.  Notice of redemption will be mailed at
least 15 days but not more than 60 days before the date fixed for redemption
to each holder of Convertible Subordinated Notes to be redeemed at his or her
registered address.  Convertible Subordinated Notes in denominations larger
than $1,000 may be redeemed in part but only in integral multiples of $1,000.
 In the event of a redemption of less than all of the Convertible
Subordinated Notes, the Convertible Subordinated Notes will be chosen for
redemption by the Trustee by lot or pro rata or, if required, in compliance
with the requirements of the


                                        A-3
<PAGE>



principal national securities exchange, if any, on which the Convertible
Subordinated Notes are listed.  On and after the redemption date interest ceases
to accrue on Convertible Subordinated Notes or portions of them called for
redemption (unless the Company defaults in the payment of the redemption price).
If this Convertible Subordinated Note is redeemed on a date which is also an
Interest Payment Date, the interest payment due on such date will be paid to the
person in whose name this Convertible Subordinated Note is registered at the
close of business on such record date.
    

   
      7.    DESIGNATED EVENT.  Upon a Designated Event, the Company shall
make a Designated Event Offer to repurchase all outstanding securities at a
price equal to 101% of the aggregate principal amount of the Convertible
Subordinated Notes, plus accrued and unpaid interest to, but excluding, the
date of repurchase, such offer to be made as provided in the Indenture.  To
accept the Designated Event Offer, the holder hereof must comply with the
terms thereof, including surrendering this Convertible Subordinated Note,
with the "Option of Holder to Elect Repurchase" portion hereof completed, to
the Company, a depositary, if appointed by the Company, or a Paying Agent, at
the address specified in the notice of the Designated Event Offer mailed to
holders as provided in the Indenture, prior to termination of the Designated
Event Offer.
    

   
      8.    SUBORDINATION.  The Company's payment of the principal of,
premium, if any, and interest on the Convertible Subordinated Notes
(including, without limitation, any amounts paid by the Company to purchase
or repurchase any Convertible Subordinated Notes) is subordinated to the
prior payment in full of the Company's Senior Debt as set forth in the
Indenture.  Each holder of Convertible Subordinated Notes by his or her
acceptance hereof covenants and agrees that all payments of the principal of,
premium, if any, and interest on the Convertible Subordinated Notes
(including, without limitation, any amounts paid by the Company to purchase
or repurchase any Convertible Subordinated Notes) by the Company shall be
subordinated in accordance with the provisions of Article 11 of the
Indenture, and each holder of Convertible Subordinated Notes accepts and
agrees to be bound by such provisions.
    

   
      9.    DENOMINATIONS, TRANSFER, EXCHANGE.  The Convertible Subordinated
Notes are in registered form without coupons in denominations of $1,000 and
integral multiples of $1,000.  The transfer of Convertible Subordinated Notes
may be registered and Convertible Subordinated Notes may be exchanged as
provided in the Indenture.  As a condition of transfer, the Registrar may
require a holder, among other things, to furnish appropriate endorsements and
transfer documents and the Company may require a holder to pay any taxes and
fees required by law or permitted by the Indenture.  The Registrar need not
exchange or register the transfer of any Convertible Subordinated Note or
portion of a Convertible Subordinated Note selected for redemption or
submitted for repurchase.  Also, it need not exchange or register the
transfer of any Convertible Subordinated Note for a period of 15 days before
a selection of Convertible Subordinated Notes to be redeemed.
    

      10.   PERSONS DEEMED OWNERS.  The registered holder of a Convertible
Subordinated Note may be treated as its owner for all purposes.

      11.   AMENDMENTS AND WAIVERS.  Subject to certain exceptions, the
Indenture or the Convertible Subordinated Notes may be amended with the consent
of the holders of at least a majority in principal amount of the then
outstanding Convertible Subordinated Notes and any existing default may be
waived with the consent of the holders of a majority in principal amount of the
then outstanding Convertible Subordinated Notes.
    

      Without the consent of any holder, the Indenture or the Convertible
Subordinated Notes may be amended to: (a) cure any ambiguity, defect or
inconsistency; (b) provide for uncertificated Convertible Subordinated Notes
in addition to or in place of certificated Convertible Subordinated Notes;
(c) provide for the assumption of the Company's obligations to holders of
Convertible Subordinated Notes in the event of consolidation, merger or sale
of all or substantially all of the assets of the Company; (d) provide for
conversion rights of holders of Notes in certain events such as a
consolidation, merger or sale of all or substantially all of the assets of
the Company; (e) reduce the Conversion Price; (f) make any change that would
provide any additional rights or benefits to the holders of Convertible
Subordinated Notes or that does not adversely affect the legal rights under
the Indenture of any such holder; or (g) comply with requirements of the
Commission in order to effect or maintain the qualification of the Indenture
under the TIA.

   
      Without the consent of each holder affected, amendment or waiver may
not (with respect to any Convertible Subordinated Notes held by a
non-consenting holder): (a) reduce the principal amount of Convertible
Subordinated Notes whose holders must consent to an amendment, supplement or
waiver; (b) reduce the principal or change the fixed maturity of any
Convertible Subordinated Note or [except as permitted pursuant to the
immediately preceding paragraph] alter the provisions with respect to the
redemption of the Convertible Subordinated Notes; (c) reduce the rate of
or change the time for payment of interest on any Convertible Subordinated
Notes; (d) waive a Default or Event of Default in the payment of principal or
premium, if any, or interest on the Convertible Subordinated Notes (except a
rescission of acceleration of the Convertible Subordinated Notes by the holders
of at least a majority in aggregate principal amount of the Convertible
Subordinated Notes and a waiver of the payment default that resulted from such
acceleration); (e) make any Convertible Subordinated Note payable in money
other than that stated in the Convertible Subordinated Notes; (f) make any
change in the provisions of the Indenture relating to waivers of past Defaults
or the rights of holders of Convertible Subordinated Notes to receive payments
of principal of, premium, if any, or interest on the Convertible Subordinated
Notes; (g) waive a redemption payment with respect to any Convertible
Subordinated Note; (h) make any change in the foregoing amendment and waiver
provisions or; (i) except as permitted by the Indenture, increase the
Conversion Price or [except as permitted pursuant to the immediately preceding
paragraph] modify the provisions of the Indenture relating to the conversion
of the Convertible Subordinated Notes in a manner adverse to the holders
thereof. In addition, any amendment to the provisions of Article 11 of the
Indenture (which relate to subordination) will require the consent of the
holders of at least 75% in aggregate principal amount of the Convertible
Subordinated Notes then outstanding if such amendment would adversely affect
the rights of holders of Convertible Subordinated Notes.
    

      12.    DEFAULTS AND REMEDIES.  An Event of Default is:  (a) default in
payment of the principal of, or premium, if any, on the Convertible
Subordinated Notes, whether or not such payment is prohibited by the
subordination provisions of the Indenture; (b) default for 30 days in payment
of any installment of interest on the Convertible Subordinated Notes, whether
or not such payment is prohibited by the subordination provisions of the
Indenture; (c) default by the Company for 60 days after notice in the
observance or performance of any other covenants in the Indenture; (d)
default in the payment of the Designated Event Payment in respect of the
Convertible Subordinated Note on the date therefor, whether or not such
payment is prohibited by the subordination provisions of the Indenture; (e)
failure to provide timely notice of a Designated Event; (f) failure of the
Company or any Material Subsidiary to make any payment at maturity, including
any applicable grace period, in respect of indebtedness for borrowed money
of, or guaranteed or assumed by, the Company or any Material Subsidiary which
payment is in an amount in excess of $25,000,000 and continuance of such
failure for 30 days after notice; (g) default by the Company or any Material
Subsidiary with respect to any such indebtedness, which default results in
the acceleration of such indebtedness in an amount in excess of $25,000,000
without such indebtedness having been discharged or such acceleration having
been cured, waived, rescinded, or annulled for 30 days after notice; or (h)
certain events involving bankruptcy, insolvency or reorganization of the
Company or any Material Subsidiary.  If an Event of Default occurs and is
continuing, the Trustee or the holders of at least 25% in principal amount of
the then outstanding Convertible Subordinated Notes may declare all the
Convertible Subordinated Notes to be due and payable immediately, except that
in the case of an Event of Default arising from certain events of bankruptcy
or insolvency, all outstanding Convertible Subordinated Notes become due and
payable without further action or notice.  Holders of Convertible
Subordinated Notes may not enforce the Indenture or the Convertible
Subordinated Notes except as provided in the Indenture.  The

                                        A-5
<PAGE>



Trustee may require an indemnity satisfactory to it before it enforces the
Indenture or the Convertible Subordinated Notes.  Subject to certain
limitations, holders of a majority in principal amount of the then outstanding
Convertible Subordinated Notes may direct the Trustee in its exercise of any
trust or power.  The Trustee may withhold from holders notice of any continuing
default (except a default in payment of principal or interest) if it determines
that withholding notice is in their interests.  The Company must furnish annual
compliance certificates to the Trustee.

      13.   TRUSTEE DEALINGS WITH THE COMPANY.  The Trustee or any of its
Affiliates, in their individual or any other capacities, may make or continue
loans to or guaranteed by, accept deposits from and perform services for the
Company or its Affiliates and may otherwise deal with the Company or its
Affiliates as if it were not Trustee.

      14.   NO RECOURSE AGAINST OTHERS.  No director, officer, employee or
stockholder, as such, of the Company shall have any liability for any
obligations of the Company under the Convertible Subordinated Notes or the
Indenture or for any claim based on, in respect of or by reason of such
obligations or their creation.  Each holder by accepting a Convertible
Subordinated Note waives and releases all such liability.  The waiver and
release are part of the consideration for the Convertible Subordinated Notes.

      15.   AUTHENTICATION.  This Convertible Subordinated Note shall not be
valid until authenticated by the manual signature of the Trustee or an
authenticating agent.

      16.   ABBREVIATIONS.  Customary abbreviations may be used in the name of a
holder or an assignee, such as: TEN CO = tenants in common, TEN ENT = tenants by
the entireties, JT TEN = joint tenants with right of survivorship and not as
tenants in common, CUST = Custodian and U/G/M/A = Uniform Gifts to Minors Act.

   
      17.   CONVERSIONS.  Subject to and upon compliance with the provisions
of the Indenture, the registered holder of this Convertible Subordinated Note
has the right at any time prior to the close of business on the last trading
day prior to October 1, 2005 (or in case this Convertible Subordinated Note
or any portion hereof shall be called for redemption prior to such date, then
on or prior to the close of business on the last trading day preceding the
date fixed for redemption), to convert the principal amount hereof, or any
portion of such principal amount which is $1,000 or an integral multiple
thereof, into that number of fully paid and nonassessable whole shares of
common stock of the Company ("Common Stock") obtained by dividing the
principal amount of the Convertible Subordinated Note or portion thereof to
be converted by the conversion price of $__.__ per share, as adjusted from
time to time as provided in the Indenture (the "Conversion Price"), upon
surrender of this Convertible Subordinated Note to the Company at the office
or agency maintained for such purpose (and at such other offices or agencies
designated for such purpose by the Company), accompanied by written notice of
conversion duly executed (and if the shares of Common Stock to be issued on
conversion are to be issued in any name other than that of the registered
holder of this Convertible
    

                                        A-6

Subordinated Note) by instruments of transfer, in form satisfactory to the
Company, duly executed by the registered holder or its duly authorized
attorney) and, in case such surrender shall be made during the period
starting after the close of business on the Regular Record Date immediately
preceding any Interest Payment Date through the close of business on the last
trading day preceding such Interest Payment Date (unless this Convertible
Subordinated Note or the portion thereof being converted is subject to
redemption on a redemption date in that period), also accompanied by payment
in funds acceptable to the Company of an amount equal to the interest
otherwise payable on such Interest Payment Date on the principal amount of
this Convertible Subordinated Note then being converted.  Subject to the
aforesaid requirement for a payment in the event of conversion after the
close of business on a Regular Record Date immediately preceding an Interest
Payment Date, no payment or adjustment shall be made on conversion for
interest accrued hereon or for dividends on Common Stock delivered on
conversion.  The right to convert this Convertible Subordinated Note is
subject to the provisions of the Indenture relating to conversion rights in
the case of certain consolidations, mergers, or sales or transfers of
substantially all the Company's assets.
    

      The Company shall not issue fractional shares or scrip representing
fractions of shares of Common Stock upon any such conversion, but shall make an
adjustment therefor in cash on the basis of the then current market value of
such fractional interest as provided in the Indenture.

   
      The Company will furnish to any holder upon written request and without
charge a copy of the Indenture.  Requests may be made to:  General Counsel,
VLSI Technology, Inc., 1190 McKay Drive, San Jose, CA 95131.

    Re:   VLSI Technology, Inc.
          Registration Statement on Form S-3
          -----------------------------------


Ladies and Gentlemen:

   
     At your request, we have examined the Registration Statement on Form S-3
(File No. 33-62161) (the "Registration Statement") filed by VLSI
Technology, Inc. (the "Company") with the Securities and Exchange
Commission (the "Commission") on August 28, 1995 together with Amendment
No. 1 thereto in the form in which it is proposed to be filed with the
Commission on or about September 7, 1995 (the "Amendment") in connection
with the registration under the Securities Act of 1933, as amended (the
"Act"), of the Company's $172,500,000 aggregate principal amount of ___%
Convertible Subordinated Notes due 2005 (the "Notes") (including
$22,500,000 in aggregate principal amount subject to an over-allotment option
to be granted to the Underwriters) and the Company's Common Stock, $0.01 par
value, into which the Notes may be converted (the "Common Stock") pursuant
to the proposed form of Indenture to be filed as an exhibit to the Amendment
(the "Indenture"), between the Company and Harris Trust and Savings Bank,
as Trustee.  The Notes are to be issued pursuant to the Indenture and sold
pursuant to an Underwriting Agreement (the "Underwriting Agreement") in
substantially the form filed as an exhibit to the Amendment.  The Notes and
the Common Stock are to be issued from time to time as set forth in the
Registration Statement, as amended by the Amendment, the Prospectus contained
therein (the "Prospectus") and the supplements to the Prospectus (the
"Prospectus Supplements"), if any.
    

   
     We have examined instruments, documents and records that we deemed
relevant and necessary for the basis of our opinion hereinafter expressed.
In such examination, we have assumed the following:  (a) the authenticity of
original documents and the genuineness of all signatures; (b) the conformity
to the originals of all documents submitted to us as copies; and (c) the
truth, accuracy and completeness of the information, representations and
warranties contained in the records, documents, instruments and certificates
we have reviewed.
    

     We are advised by the Company that its Common Stock is quoted on the
Nasdaq National Market, and we have relied on that fact in rendering our
opinions set forth below.  In addition, we express no opinion as to the
enforceability of the Notes and the Indenture at any future date if on such
date the Company no longer has any security quoted on the Nasdaq National
Market or if the Nasdaq


<PAGE>

National Market ceases to be certified by the California Commissioner of
Corporations pursuant to subdivision (o) of Section 25100 of the California
Corporations Code.

     Based on such examination, we are of the opinion that:

   
     1. When the issuance of the Notes has been duly authorized by
appropriate corporate action of the Company and the Notes, in the form filed
as an exhibit to the Registration Statement, have been duly completed,
executed, authenticated and delivered in accordance with the Indenture and
sold pursuant to the Underwriting Agreement and as described in the
Registration Statement, any amendment thereto, the Prospectus and any
Prospectus Supplement relating thereto, the Notes will be valid and binding
obligations of the Company, entitled to the benefits of such Indenture.
    

   
     2. When the issuance of the Common Stock has been duly authorized by
appropriate corporate action of the Company and the Common Stock has been
duly issued, sold and delivered in accordance with the Indenture and as
described in the Registration Statement, any amendment thereto, the
Prospectus and any Prospectus Supplement relating thereto, the Common Stock
will be legally and validly issued, fully paid and nonassessable.
    

   
     Our opinion that any document is valid and binding is qualified as to:
    

     (a) limitations imposed by bankruptcy, insolvency, reorganization,
arrangement, fraudulent conveyance, moratorium or other laws relating to or
affecting the rights of creditors generally; and

     (b) general principles of equity, including without limitation concepts
of materiality, reasonableness, good faith and fair dealing, and the possible
unavailability of specific performance or injunctive relief, regardless of
whether such enforceability is considered in a proceeding in equity or at law.

   
     We hereby consent to the filing of this opinion as an exhibit to the
above-referenced Registration Statement and Amendment and to the use of our
name wherever it appears in the Registration Statement, the Prospectus,
Prospectus Supplement and in any amendment or supplement thereto.  In giving
such consent, we do not believe that we are "experts" within the meaning of
such terms as used in the Act or the rules and regulations of the Securities
and Exchange Commission issued thereunder with respect to any part of the
Registration Statement, including this opinion as an exhibit or otherwise.
    


                                     Very truly yours,

under the Credit Agreement; and

    WHEREAS, the Borrower desires to incur new subordinated indebtedness.

   
    NOW,  THEREFORE,  in  consideration of  the  premises, and  intending  to be

meetings whenever requested in writing so to do by stockholders owning a

event such notice shall be given within the time and published as provided
for in the following Section 3.

quorum, may designate another member or other members of the Board of
Directors to act at such meeting, and any director or directors so designated
shall have the same powers, duties and compensation as regular members.  The
presence at the meeting of any director or directors so designated shall be
considered in determining whether a quorum is present.

SECTION 3.  VACANCIES.  Vacancies in the Board of Directors may be filled for
the unexpired term at a special meeting of the stockholders called for that
purpose.  Additionally, the Board of Directors pursuant to paragraph (5) of

other time, which may be a legal holiday, as the Board of Directors may
determine.  All such regular meetings shall be held at the offices of the

Board or the President may at any time designate, and in the event of such

the same to each director not later than five business days preceding the
date of the meeting, or by telegraphing the same to him or delivering the
same to him personally not later than the day previous to such meeting, but
save for any such notice of alternate meeting place, such regular meetings
shall be held without other notice than this bylaw. Special meetings may be
called by the Chairman of the Board, a Vice Chair of the Board or the
President or by or at a written request of any three directors.  Except to
the extent the time or method of giving notice is regulated by statute,
notice of any such meeting shall be given by mailing the same to each
director not later than five business days preceding the date of the meeting,
or by telegraphing the same to him or by delivering the same to him
personally not later than the day previous to such meeting.  Any director may
waive notice of any meeting by waiver signed either

these bylaws, neither the business to be transacted at nor the purpose of any
meeting need be specified in the notice or waiver.

constitute a quorum for the transaction of business at any meeting of the
Board of Directors, but less than a quorum shall have power to take a recess
or adjourn a meeting to another day or hour.

SECTION 6.  SECRETARY OF THE BOARD.  The Board of Directors may appoint a
Secretary of the Board other than the Secretary of the Bank as provided for

                                ARTICLE IV:  SEAL

of stock of the Bank upon assignment by such fiduciary, shall be made by the

                            ARTICLE VII:  AUDITS


SECTION 1.  SCOPE.  The scope of and the procedures or tests to be followed
in the auditing division in examining the books, assets, liabilities and
affairs of the Bank and reporting thereon to the Board of Directors, and the
extent and manner of coordinating such examination and report into or with
any audit report by certified public accountants, shall be such as may be
from time to time prescribed by the Board of Directors or by an Examining
Committee appointed from time to time by the Board of Directors and
consisting of at least two directors who are not officers of the Bank.

SECTION 2.  REPORTS.  The Auditor, or the officer designated by the Board as
responsible for the supervision of the auditing division, shall report under
seal to the Examining Committee appointed by the Board of Directors and, if
none is appointed, to the Board of Directors, itself, on the audit program
and internal controls in each quarter of the year and shall appear at any
time at the request of the Board of Directors or the Executive Committee at
any regular or special meetings thereof and report on the results of
examinations, the soundness of condition of the Bank and any other pertinent
information in connection therewith.  The Auditor, or officer designated by
the Board as responsible for the supervision of the auditing division, shall
have continuing responsibility to report promptly under seal to the Board of
Directors or the Executive Committee any material irregularities which in his
opinion are of sufficient importance to be brought to their attention before
his next quarterly report.


                        ARTICLE VIII:  INDEMNIFICATION


SECTION 1.  APPLICABILITY.  Every person now or heretofore or hereafter
serving as a director, officer or employee of the Bank or of a wholly owned
subsidiary of the Bank, and every officer or employee of the Bank or of any
such wholly owned subsidiary now, heretofore or hereafter serving as director
or officer of one or more other corporations or organizations, or as trustee,
executor, administrator, guardian or conservator or in a similar fiduciary
capacity, at the request of the Bank as evidenced by action of the Executive
Committee or the Board designating the situation as one entitled to the
benefit of this bylaw or to the benefit of a similar indemnifying resolution
of the Board, shall be indemnified or reimbursed by the Bank from and for
expenses, liabilities, fines, penalties and costs that may be imposed upon or
incurred by him, including by way of settlement, in connection with any
action, suit, or proceeding, civil or criminal, in which he may be or become
a party by reason of his being or having been such director, officer,
trustee, executor, administrator, guardian, conservator or other


<PAGE>

such fiduciary; provided, however, that no such person shall be entitled to
such indemnity or reimbursement.

     (a) in relation to matters as to which he shall be finally adjudged in
an action brought by the Bank directly or derivatively to be liable for
breach of a duty to or for nonpayment of a liability to the Bank; or

     (b) in relation to matters included in an action, suit or proceeding of
the kind referred to in the foregoing subparagraph (a) but which is settled
or disposed of without final adjudication on the merits except and unless the
Board or, as the case may be, the stockholders, shall make the same findings
as are provided for in the following subparagraph (c) as a condition
precedent to such indemnity or reimbursement; or

     (c) in relation to matters involved in an action, suit or proceeding
which is of a kind other than that referred to in the foregoing subparagraph
(a), unless such action, suit or proceeding is dismissed or otherwise
disposed of on the merits in favor of such person, or, if not so dismissed or
disposed of, unless the Board shall find that such person acted in good faith
for a purpose which he reasonably believed to be in the best interests of the
Bank, and in the case of criminal actions or proceedings, in addition had
good warrant to believe that his conduct was not unlawful.

SECTION 2.  FINDINGS.  The action by the Board called for in subparagraph (c)
of Section 1 hereof shall be at a meeting at which a quorum consisting of
directors who are not parties to such suit, action or proceeding is present;
and in taking such action no director involved shall be qualified to vote
thereon. In the absence of quorum, such finding shall nevertheless be
effective if made by resolution of the stockholders adopted at an annual
meeting or at a special meeting of the stockholders.  The right of
indemnification or reimbursement provided for by this Article shall not be
exclusive and shall not affect any right to indemnification or reimbursement
which any director, officer or employee might otherwise have as a matter of
law.

The term "Bank" as used in this Article shall be deemed to include the Bank
and the predecessor bank of the same name, all with the same effect as if the
Bank and said predecessor had at all times been one and the same corporation.

SECTION 3.  LEGAL EXPENSES.  Expenses incurred by a director, officer or
employee in defending a civil or criminal action, suit or proceeding may be
paid by the Bank in advance of the final disposition of such action, suit or
proceeding as authorized by the Board of Directors in a specific case upon
receipt of an undertaking by or on behalf of the director, officer or
employee to repay such amount unless it shall ultimately be determined that
he is entitled to indemnification as provided in this Article VIII.

                 ARTICLE IX:  MANAGEMENT SUCCESSION PROVISIONS


In the temporary absence of the Chairman of the Board, the Vice Chairs of the
Board and the President, certain Senior Executive Vice Presidents, Executive
Vice Presidents, Executives or Senior Vice Presidents shall have and exercise
all the powers and duties of the Chief Executive Officer until the Board of
Directors meets to provide for permanent succession, the order of precedence
having been set by the Board of Directors referring to this Article IX.  The
provisions of this paragraph are, however, subject to the right of the
stockholder, the Board of Directors and of the Executive Committee to appoint
the presiding officer of their respective meetings.


                        ARTICLE X:  AMENDMENT OR REPEAL


These bylaws, or any part hereof, may be amended, altered, changed, added to
or repealed, and others adopted in their place by the Board of Directors of
the Bank, at any regular or special meeting.
