                                  COMMON STOCK


   
         This  Prospectus may be used only in connection  with the resale,  from
time to time, of up to 1,100,000  shares of Common Stock of Sigma Designs,  Inc.
("Sigma" or the "Company"), by the Selling Shareholders,  as listed in the table
on page 22 of this Prospectus.  All of the shares covered by this Prospectus are
to be sold by the Selling  Shareholders.  The Selling  Shareholders will receive
the shares  upon  conversion  of our Series A  Preferred  Stock and  exercise of
warrants.  This  Post-Effective  Amendment  No. 1 to the  Form S-3  Registration
Statement  is filed  to add KA  Investments  LDC as a  Selling  Shareholder.  KA
Investments  LDC  purchased  shares of  Series A  Preferred  Stock and  warrants

originally purchased Series A Preferred Stock and warrants directly from us in a
transaction  not  subject  to  registration  with the  Securities  and  Exchange
Commission. We will not receive any of the proceeds from the sale of the shares.
We will, however, pay the expenses incurred in registering the shares, including
legal and accounting fees.

         The shares  offered by this  Prospectus  may be offered and sold,  from
time to time,  by the  Selling  Shareholders,  or others who  receive the shares
pursuant  to a  valid  transfer.  Such  offers  and  sales  can  take  place  in
transactions  (including block  transactions) on the Nasdaq Stock Market (or any
other   exchange   on  which  our  Common   Stock  may  then  be   listed),   in
privately-negotiated   transactions,    broker-dealer   transactions,   exchange
transactions,  short sales, or other methods. Sales may be made at market prices
or  negotiated  prices.  The Selling  Shareholders  will pay for any  commission
expenses and brokerage fees.

         Our Common  Stock is traded on the Nasdaq Stock Market under the symbol
"SIGM."  On  December  4,  1998,  the last sale  price for our  Common  Stock as
reported on the Nasdaq Stock Market was $2.63 per share.

         You should  carefully  consider the risks described below before making
an investment decision. The risks and uncertainties  described below are not the
only ones facing our company.  Additional risks and  uncertainties not presently
known to us or that we currently  deem  immaterial  may also impair our business
operations.

         If any of the following risks actually occur,  our business,  financial
condition or results of operations could be materially  adversely  effected.  In
such case, the trading price of our Common Stock could decline, and you may lose
all or part of your investment.

         This Prospectus also contains  forward-looking  statements that involve
risks and  uncertainties.  Our actual results could differ materially from those
anticipated in these forward-looking  statements as a result of certain factors,
including  the  risks  faced  by  us  described  below  and  elsewhere  in  this
Prospectus.



<PAGE>


History of Operating Losses; Recent Significant Losses; Liquidity

         We incurred  significant  losses in fiscal 1995,  1996, 1998 and during
1999 and had substantial negative cash flow in fiscal 1995, 1996, 1997, 1998 and
during 1999.  Since our  introduction  of the REALmagic  Moving Picture  Experts
Group  ("MPEG")  product  line  in  November  1993,  we  have  made  significant
investments  in  marketing  and  technological   innovation  for  our  REALmagic
products.  As a result of our  investments,  we experienced  significant  losses
through fiscal 1996. Fiscal 1995, 1996 and 1998 also included significant losses
associated  with products other than those related to our REALmagic  technology.
Since our  inception  through July 31, 1998,  our total  accumulated  deficit is
$39,205,000.  We  cannot  assure  you  that we  will  continue  to sell  our new
REALmagic products in substantial  quantities or generate  significant  revenues
from  those  sales.  We cannot  assure  you that we will  return  to  profitable
operations in any future fiscal quarter or fiscal year. If profitable operations
are achieved, we cannot assure you that they will be sustained.

         We have an Amended and Restated  Business Loan  Agreement  with Silicon
Valley Bank,  dated  October 26, 1998.  Under the  Agreement we gave two secured
Promissory  Notes in total  principal  amounts of $12  million and $6 million to
Silicon  Valley  Bank.  Under this  Agreement  and the Notes,  we are subject to
certain covenants  relating to profitability  and financial ratios.  Since July,
1997, we have, on occasion, obtained waivers releasing us from our obligation to
meet these  covenants.  We have a waiver for the quarter ended October 31, 1998.
We expect to need another  waiver for the quarter  ending  January 31, 1999.  We
cannot assure you that Silicon Valley Bank will grant that waiver.  If we do not
meet these covenants,  and if we do not obtain another waiver,  the loans may be
in default.  If we are in default,  then the lender could accelerate payments on
the Notes and we could suffer serious harm to our business,  financial condition
and prospects.

Marketing  Risks;  Volatility  of  OEM  Customer  Sales;  Volatility  of  Resale
Distribution

         Our ability to  increase  sales,  achieve  profitability  and  maintain
REALmagic as a personal  computer ("PC") industry  multimedia  standard  depends
substantially  on our ability to achieve a sustained  high level of sales to new
Original Equipment  Manufacture  ("OEM") customers.  We have not executed volume
purchase  agreements with any of our customers.  Our customers are not under any
obligation  to  purchase  any  minimum  quantity  of our  products.  We have not
achieved  bundling  agreements  with many OEM customers to ensure the success of
our REALmagic  product line. Also, even if we achieve new design wins, we cannot
assure you that PC  manufacturers  will  purchase  our  products in  substantial
volumes.  Sales to any  particular  OEM  customer  are  subject  to  significant
variability   from  quarter  to  quarter  and  to  severe  price   pressures  by
competitors.  Based on our  experience  in the PC  industry,  we expect that our
actual sales to OEM customers will experience  significant  fluctuations.  Also,
estimates of future sales to any particular  customer or groups of customers are
inherently uncertain.

         Our  ability  to  achieve  sustained  profitability  also  depends on a
substantial  increase in the sales of REALmagic  products  through  domestic and
international  distributors for resale through corporate markets.  Sales to such
distributors are typically subject to contractual  rights of inventory


<PAGE>


rotation or price  protection.  The failure of distributors to achieve sustained
sell-through of REALmagic products could result in product returns or collection
problems. This could contribute to fluctuations in our results of operations. We
cannot assure you that we will be successful in maintaining a significant market
for our REALmagic products.

Technological Change; Uncertainty of Achievement of Technological Leadership

         The  market  for  multimedia  PC  products  is   characterized  by  the
following:  rapidly changing  technology and user preferences,  evolving formats
for compression of video and audio data, and frequent new product introductions.
Even though  REALmagic  products and related software titles have gained initial
market  acceptance,  our success depends,  among other things, on our ability to
achieve and maintain technological leadership and to remain competitive in terms
of price and product performance.

         To  have   technological   leadership,   we  must   continue   to  make
technological  advancements and research and development investments in the area
of MPEG video and audio decoding. These advancements include the following:

     o   compatibility with emerging standards and multiple platforms;
     o   improvements to the REALmagic architecture; and
     o   enhancements to the REALmagic application programming interface.

         We cannot assure you that we will be able to make these advancements to
our REALmagic  technology.  If we do make these  advances,  we cannot assure you
that we will be able to  achieve  and  maintain  technological  leadership.  Any
material failure by us or OEMs and software developers to develop or incorporate
any required  improvement could adversely affect the continued acceptance of our
technology  and the  introduction  and  sale of  future  products  based  on our
technology.  We cannot  assure you that  products or  technologies  developed by
others will not render  obsolete our  technology,  and the products based on our
technology.

         To be  competitive,  we must  anticipate  the needs of the  market  and
successfully  develop and introduce innovative new products in a timely fashion.
We cannot assure you that we will be able to successfully complete the design of
our new products,  have these products manufactured at acceptable  manufacturing
yields,  or  obtain  significant   purchase  orders  for  these  products.   The
introduction of new products may adversely affect sales of existing products and
contribute to  fluctuations  in operating  results from quarter to quarter.  Our
introduction  of new  products  also  requires  that  we  carefully  manage  our
inventory to avoid inventory obsolescence. In addition, new products, as opposed
to more mature products,  typically have higher initial  component  costs.  This
higher cost could result in downward pressures on our gross margins.

Competition

         The market for  multimedia  PC products is highly  competitive,  and is
driven by faster  processors  provided by Intel Corporation and other companies.
Intel   processors   have,  in  recent



<PAGE>


years,  included  increased  graphics  functionality.  Other companies with more
experience and financial  resources may develop a competitive product that could
inhibit future growth of our REALmagic technology.  Increased competition may be
generated from several major computer product  manufacturers that have developed
products and technologies that could compete directly with REALmagic products on
the PC platform. These competitors include:

     o   SGS Thompson Microelectronics;
     o   C-Cube Microsystems;
     o   IBM Corporation;
     o   Zoran Corporation; and
     o   LSI Logic.

         In addition, Intel processors are becoming more powerful, so that video
decoding could eventually be done in software.  Intel processors have, in recent
years, included increased graphics  functionality.  Most of our competitors have
substantial  experience and expertise in audio, video and multimedia  technology
and in producing and selling  consumer  products  through  retail  distribution.
These  companies  also have  substantially  greater  engineering,  marketing and
financial  resources  than we  have.  Our  competitors  could  form  cooperative
relationships that could present formidable  competition to us. We cannot assure
you that our REALmagic  technology  will achieve  commercial  success or that it
will compete effectively against other interactive multimedia products, services
and  technologies  that  currently  exist,  are  under  development,  or  may be
announced by competitors.

Reliance on a Single Line of Products;  Source of Net Sales;  Market  Demand for
Multimedia Products

         Our business strategy is, and has been, to focus on REALmagic  products
by  investing  heavily in  PC-based  MPEG  technology.  In the fiscal year ended
January 31, 1998 and the six months  ended July 31,  1998,  sales of  multimedia
products  accounted  for  virtually  all of our net  sales.  A decline in market
demand for multimedia  products will materially  adversely  affect our operating
results.  Our present reliance on REALmagic  products is further affected by the
fact that  multimedia  product  sales are  concentrated  in the PC  industry.  A
decline in demand for PCs could have a material  adverse effect on our operating
results and financial condition.

Variability of Operating Results; Seasonal Variations in Demand; DVD Technology

         Our operating  results have  fluctuated in the past and may continue to
fluctuate  in the  future.  This  fluctuation  is due to a  number  of  factors,
including the following and others:

     o   our new product introductions and our competitors;
     o   market acceptance of our products by OEMs,  software developers and end
         users;
     o   the success of our promotional programs;
     o   gains or losses of our significant customers;
     o   reductions in selling prices;



<PAGE>


     o   inventory obsolescence;
     o   an interrupted or inadequate supply of semiconductor chips;
     o   our ability to protect our intellectual property; and
     o   loss of our key personnel.

         In  addition,  sales  to  OEM  customers  are  subject  to  significant
variability from quarter to quarter.  This  variability  depends on OEMs' timing
and release of products that  incorporate our REALmagic  technology,  experience
with sales of these products and inventory levels.

         The  market for  consumer  electronics  products  is  characterized  by
significant  seasonal  swings in demand.  Demand  typically  peaks in the fourth
calendar quarter of each year. We expect to derive a substantial  portion of our
revenues from the sales of REALmagic  products in the future. The demand for our
products  will depend in part on the  success of digital  video  technology.  In
light of this, our revenues may vary with the availability of and demand for DVD
titles.  This demand may increase or decrease as a result of a number of factors
that cannot be predicted, such as consumer preferences and product announcements
by competitors.

         Announcements  of  directly  competing  products  will  likely  have  a
negative effect on our operating  results.  Based on our experience,  we believe
that a substantial  portion of our shipments  will occur in the third month of a
quarter,  with significant  shipments  completed in the latter part of the third
month.  This shipment pattern may cause our operating results to be difficult to
predict.  Currently,  we place noncancellable  orders to purchase  semiconductor
products from our foundries with a long lead time. Consequently, if, as a result
of inaccurate  forecasts or cancelled purchase orders, our anticipated sales and
shipments in any quarter do not occur when expected,  our inventory levels could
be disproportionately  high. This could require significant working capital, and
negatively affect our operating results.

Manufacturing  Risks;  Reliance on  Independent  Suppliers;  Forecasting  Risks;
Production Delay Risks

         Our REALmagic  products and  components are presently  manufactured  by
outside  suppliers or foundries.  We do not have long-term  contracts with these
suppliers.  We conduct  business with our suppliers on a written  purchase order
basis. Our reliance on independent suppliers subjects us to several risks. These
risks include:

     o   the absence of adequate capacity;
     o   the  unavailability  of, or interruptions in access to, certain process
         technologies; and
     o   reduced  control  over  delivery  schedules,  manufacturing  yields and
         costs.

We obtain some of our components from a single source.  Delays or  interruptions
have not occurred to date, but any delay or interruption in the supply of any of
the  components  required for the  production of our REALmagic  multimedia  card
currently  obtained from a single source could have a material adverse impact on
our sales of REALmagic products, and on our business.



<PAGE>


         We must provide our  suppliers  with  sufficient  lead time to meet our
forecasted  manufacturing  objectives.  Any  failure to properly  forecast  such
quantities  could materially  adversely affect our ability to produce  REALmagic
products  in  sufficient  quantities.  We cannot  assure you that our  forecasts
regarding new product demand will be accurate,  particularly because we sell our
REALmagic  products  on a purchase  order  basis.  Manufacturing  the  REALmagic
chipsets is a complex process, and we may experience short-term  difficulties in
obtaining  timely  deliveries.  This could  affect our ability to meet  customer
demand for our  products.  Any such delay in  delivering  products in the future
could materially and adversely affect our operating results. Also, should any of
our major  suppliers  become unable or unwilling to continue to manufacture  our
key  components  in  required  volumes,  we will have to  identify  and  qualify
acceptable  additional  suppliers.  This qualification  process could take up to
three months or longer and additional sources of supply may not be in a position
to satisfy our requirements on a timely basis.

         In  the  past,  we  have  experienced   production   delays  and  other
difficulties,  and we  could  experience  similar  problems  in the  future.  In
addition,  product defects may occur and they may escape  identification  at the
factory. This could result in unanticipated costs,  cancellations,  deferrals of
purchase orders, or costly recall of products from customer sites.
    

Dependence on Key Personnel

   
         Our future  success  depends in large part on the continued  service of
our  key  technical,  marketing,  sales  and  management  personnel.  Given  the
complexity  of REALmagic  technology,  we are dependent on our ability to retain
and  motivate  highly  skilled  engineers  involved in the ongoing  hardware and
software  development  of REALmagic  products.  These  engineers are required to
refine the existing hardware system and application programming interface and to
introduce  enhancements  in future  applications.  The multimedia PC industry is
characterized  by high level  employee  mobility and  aggressive  recruiting  of
skilled personnel.  Despite incentives we provide to them, our current employees
may not continue to work for us, and if additional  personnel  were required for
our operations,  we may not able to obtain the services of additional  personnel
necessary for our growth. We do not have "keyperson" life insurance  policies on
any of our employees.

Limited   Intellectual   Property   Protection;   Patents  and  Pending   Patent
Applications; Litigious Sector

         Our  ability to compete  may be  affected by our ability to protect our
proprietary  information.  We currently hold ten patents covering the technology
underlying the REALmagic products. We have filed certain patent applications and
are in the process of preparing  others.  We cannot  assure that any  additional
patents for which we have applied will be issued or that any issued patents will
provide meaningful  protection of our product  innovations.  Like other emerging
multimedia  companies,  we rely  primarily  on trade  secrets and  technological
know-how in the conduct of our business. We also rely, in part, on copyright law
to protect our proprietary rights with respect to REALmagic  technology.  We use
measures  such  as  confidentiality   agreements  to  protect  our  intellectual
property.  These  methods of  protecting  our  intellectual  property may not be
sufficient.



<PAGE>


         The  electronics  industry  is  characterized  by  frequent  litigation
regarding  patent and intellectual  property  rights.  Any such litigation could
result in significant  expense to us and divert the efforts of our technical and
management personnel.  In the event of an adverse result in any such litigation,
we could be required to expend  significant  resources to develop  noninfringing
technology or to obtain  licenses to the  technology  that is the subject of the
litigation,  and we may not be  successful in such  development  or in obtaining
such licenses on acceptable  terms,  if at all. In addition,  patent disputes in
the  electronics  industry  have  often  been  settled  through  cross-licensing
arrangements. Because we do not yet have a large portfolio of issued patents, we
may not be able to  settle  an  alleged  patent  infringement  claim  through  a
cross-licensing arrangement.

Risks of International  Operations;  Substantial Percentage of Net Sales Derived
From the Asia Pacific Region

         During the fiscal years ended January 31, 1998, 1997 and 1996, sales to
international  customers accounted for approximately 64%, 72% and 63% of our net
sales,  respectively.  We  anticipate  that  sales to  international  customers,
including  sales  of  REALmagic  products,   will  continue  to  account  for  a
substantial  percentage  of our net  sales.  Also,  some of the  foundries  that
manufacture our products and components are located in Asia.  Overseas sales and
purchases to date have been denominated in U.S. dollars.

         Due to the  concentration of international  sales and the manufacturing
capacity  in  Asia,  we  are  subject  to  the  risks  of  conducting   business
internationally.   These  risks   include   unexpected   changes  in  regulatory
requirements  and  fluctuations in the U.S. dollar that could increase the sales
price in local currencies of our products in international  markets,  or make it
difficult for the Company to obtain price  reductions from its foundries.  We do
not  currently  engage in any  hedging  activities  to reduce  our  exposure  to
exchange  rate  risks.  If  and  when  we  engage  in  transactions  in  foreign
currencies,  our results of operations  could be adversely  affected by exchange
rate fluctuations.

         We derive a substantial  portion of our revenues from sales to the Asia
Pacific  region.  This  region of the world is  subject to  increased  levels of
economic instability,  and this instability could have a material adverse effect
on our results of operations.
    

Volatility of Stock Price

   
         The  market  of our  Common  Stock  has  been  subject  to  significant
volatility.  This  volatility is expected to continue.  The  following  factors,
among others,  may have a  significant  impact on the market price of our Common
Stock:

     o   our announcement of the introduction of new products;
     o   our competitors' announcements of the introduction of new products;
     o   market conditions in the technology,  entertainment and emerging growth
         company sectors; and
     o   short sales by shareholders and others.



<PAGE>


         The  stock  market  has  experienced,  and is  currently  experiencing,
volatility that  particularly  affects the market prices of equity securities of
many high  technology  and  development  stage  companies,  such as those in the
electronics industry.  This volatility is often unrelated or disproportionate to
the operating  performance of such  companies.  These  fluctuations,  as well as
general economic and market conditions,  could adversely affect the price of our
Common Stock.

Potential for Dilution from Conversion of Series B Preferred Stock

         Series B Preferred  Stock. As of December 7, 1998,  2,250 shares of our
Series B Convertible Preferred Stock were issued and outstanding.  The shares of
Series B Preferred  Stock are convertible at the option of the holders into that
number of shares of Common Stock as is  generally  determined  by the  following
formula:

     o   Multiply the stated value ($1,000) by the number of outstanding  shares
         of Series B Preferred  Stock (under certain  circumstances,  this value
         may be increased by a premium  based on the number of days the Series B
         Preferred  Stock is held),  and divide the product by the then  current
         Conversion Price (set forth below).

     o   The Conversion  Price is based on the average of the lowest six trading
         prices of our Common  Stock in the twenty  trading  days ending one day
         prior to the date of conversion of the Series B Preferred Stock.  Thus,
         if the Series B Preferred  Stock was converted on December 7, 1998, the
         Conversion Price would have been $2.06.

         Based on this formula, if the remaining  outstanding Series B Preferred
Stock was  converted on December 7, 1998,  it would have been  convertible  into
approximately  1,092,233  shares of Common  Stock.  This  number can prove to be
significantly  greater in the event of a decrease  in the  trading  price of our
Common  Stock.  Purchasers  of our  Common  Stock  will  experience  substantial
dilution of their  investment upon  conversion of the Series B Preferred  Stock.
However,  in the event the price of our Common Stock falls below $3.26,  subject
to applicable  laws  restricting  our repurchase of stock, we have the option to
elect to pay cash (at a premium to the then  current  market price of our Common
Stock) to the  holders of Series B  Preferred  Stock in lieu of  converting  the
shares  of  Series B  Preferred  Stock.  In the  event  we  elect  to pay  cash,
purchasers  of our Common Stock will suffer less  dilution.  Our election to pay
cash,  however,  will come at the expense of diverting our available  cash funds
from  other  potential  uses.  The  shares of Series B  Preferred  Stock are not
registered  and may be sold only if registered  under the Securities Act or sold
in accordance with an applicable exemption from registration, such as Rule 144.

         As of December 7, 1998,  warrants to purchase  50,000  shares of Common
Stock issued to the purchasers of the Series B Preferred  Stock and  exercisable
for a period of three years following May 1, 1998 at a price of $5.16 (as may be
adjusted  from  time  to  time  under  certain  antidilution   provisions)  were
outstanding.



<PAGE>


         As of December 7, 1998,  5,854,398 shares of Common Stock were reserved
for issuance upon exercise of our  outstanding  warrants and options  (excluding
the warrants  issued to the  purchasers of the Series B Preferred  Stock) and an
additional  4,300,000  shares of Common Stock were  reserved  for issuance  upon
conversion  of the  preferred  stock and exercise of the warrants  issued to the
purchasers  of the Series B Preferred  Stock.  At October 31,  1998,  there were
13,514,735  shares of Common Stock  outstanding.  Of these  outstanding  shares,
13,492,952 were freely  tradable  without  restriction  under the Securities Act
unless held by affiliates who are subject to certain  limitations under Rule 144
of the Securities Act of 1933, as amended.
    

       

Impact of the Year 2000 Issue

   
         Year 2000  Compliance.  We are aware of the issues  associated with the
programming code in existing  computer systems as the year 2000 approaches.  The
"year 2000  problem"  is  pervasive  and  complex as  virtually  every  computer
operation  will be affected in some way by the  rollover of the  two-digit  year
value to 00. The issue is whether computer systems will properly  recognize date
sensitive  information  when  the year  changes  to  2000.  Systems  that do not
properly  recognize such  information  could generate  erroneous data or cause a
system to fail.

         We have tested our  products  and believe  our  products  are year 2000
compliant.  Our  management  has also  conducted a review of our exposure to the
year 2000 problem, including working with computer systems and software vendors.
We currently  believe that our internal  systems are year 2000 compliant.  We do
not expect to further  incur any  significant  operating  expenses  or invest in
additional computer systems to resolve issues relating to the year 2000 problem,
with  respect  to both  our  information  technology  and  product  and  service
functions.

         However,  significant uncertainty remains concerning the effects of the
year 2000 problem,  including  uncertainty regarding assurances made by vendors.
In addition, we have not investigated year 2000 compliance of other entities who
are not our  vendors  or who are  vendors  or  purchasers  of our  product.  For
example,  we do not  have  control  over  the  compliance  of our  distributors,
partners, banks, stock markets or systems in which our products are used.

         We cannot assume that third parties will be year 2000 compliant, and if
they  are  not,  we  cannot  assume  that we will  not be  subject  to  actions,
liabilities  or  damages  associated  with  these  failures.   We  will  develop
appropriate  contingency  plans in the event that a significant  exposure arises
relative to any such third parties.

                                   THE COMPANY

Overview

         The following  sections  regarding the Company contain  forward-looking
statements that involve risks and  uncertainties.  The Company's  actual results
could  differ  materially  from  those  anticipated  in  these   forward-looking
statements  as a result of certain  factors,  as discussed in this  Registration
Statement.

         We design,  manufacture  (using  subcontractors)  and market multimedia
products for use with personal computers. The emergence of multimedia technology
in the personal  computer (PC) market has dramatically  changed the way in which
users interact with computers. Multimedia integrates different elements, such as
sound and video,  to enhance the computing  experience  and deliver a heightened
sense of realism.  Through  its  REALmagic  product  line  incorporating  Moving
Picture  Experts Group (MPEG)  technology,  Sigma Designs has become a leader in
this emerging market.

         Prior to MPEG's introduction, video on personal computers suffered from
serious  drawbacks.  Motion pictures  appeared jerky,  and video was confined to
small window sizes. MPEG, a defined International  Standards  Organization (ISO)
standard  for  video   compression,   eliminated  many  of  those  problems  and
revolutionized  multimedia  on the PC platform.  For the first time,  MPEG users
could play back full-screen,  full-motion video combined with stereo audio, even
from a standard CD-ROM. A single CD-ROM using the MPEG compression technique can
store up to 74 minutes of full motion video and audio.

         With MPEG  technology,  producers  can create  (and users can enjoy) an
interactive,  television-like  experience  on a  desktop  PC.  The  result  is a
significant new visual impact, thereby opening possibilities for a wide range of
entertainment,  education,  training and business presentation applications.  In
April 1997, the Company  announced its entry into the Digital Video Disk ("DVD")
market. A key element of the DVD  specification is the use of MPEG-2 for digital
video  compression,  a  technology  in which  Sigma has  established  expertise.
Sigma's REALmagic EM8300,  EM8220 and EM8800 PC-based DVD and SVCD solutions are
extensions  of the  Company's  MPEG  expertise  and provide a  highly-integrated
solution for the PC-DVD and PC-SVCD markets.
    

The REALmagic MPEG Standard

         Since its first  shipment in November  1993,  REALmagic  technology has
received  support  from PC industry  leaders,  software  developers  and OEM and
retail customers.

Partnership with PC Industry Leaders

   
         Sigma has  developed  strategic  partnerships  to  develop  and  market
network  streaming video products with companies such as Hughes Network Systems,
IBM,  Microsoft  Corporation,   Oracle  Corporation,   Silicon  Graphics,  Inc.,
Starlight Networks, Sun Microsystems, OptiVision and FVC.com.
    

<PAGE>

   
Support from Software Developers

         Support for Sigma's  REALmagic  MPEG  standard  has grown to over 1,200
software developers. To further expand the list of developers,  Sigma has worked
directly with Microsoft on Microsoft's new streaming  standard for MPEG-2 called
DirectShow.  Sigma Designs is the first and currently the only company  shipping
drivers with DirectShow  support for streaming MPEG-2 video,  making it the only
recommended decoder for use with Microsoft's NetShow Theater video server.

         Using the DirectShow standard, software developers can create streaming
video applications with virtually any video  server-without any C programming at
all. This enables  universities  and corporations to get live video and video on
demand applications online very rapidly, which shortens the sales process.
    

Support from OEMs

   
         In the  United  States,  Dell  Computer  Corporation,  Compaq  Computer
Corporation, IBM, Hughes Network Systems and OptiVision have purchased REALmagic
cards for installation  inside their systems for streaming video.  Additionally,
Philips,  Sony, Panasonic Canada,  Matsushita,  Toshiba,  VideoLogic and several
other companies market DVD kits that include  REALmagic  Hollywood Plus playback
cards,  and several  vendors  base their DVD systems on  REALmagic  DVD playback
cards.

Acceptance by the Corporate Market

         REALmagic is the most  well-known  and most  recognized  brand name for
MPEG video on PCs. Sigma Designs has developed this brand name through marketing
campaigns and by building a reputation for delivering and supporting inexpensive
MPEG decoders with robust, powerful and flexible software drivers. This has made
Sigma  Designs'  REALmagic the de facto standard for corporate  market  projects
such as corporate-wide rollouts at Merrill Lynch, Smith Barney and Wal-Mart.

REALmagic Business Strategy
    

         Sigma's corporate  objective is to continue to be a leading provider of
MPEG multimedia products that enable full-screen,  full-motion,  TV-like quality
video on the standard  desktop and the notebook PC. To accomplish  this goal the
Company intends to promote widespread  acceptance of REALmagic  technology.  The
key parts of this strategy include:

<PAGE>

   
Win More OEM Partnerships and Further Penetrate the Corporate Market

         To  establish  REALmagic  for MPEG-2 as a standard,  the  Company  will
continue to seek design wins with major PC manufacturers worldwide, in which the
OEMs will  factory-install  REALmagic boards or chipsets inside their multimedia
PCs. On the retail  side,  the  Company's  systems  integration  sales team will
continue  to work with its network of national  distributors  and special  Value
Added Resellers  (VARs) to distribute its high-end  REALmagic  playback card. In
Europe and Asia Pacific,  the Company will  continue to expand its  relationship
with  distributors as well as OEMs and VARs. In addition,  the Company will seek
to sell  chipsets to add-on card  manufacturers  that will,  in turn,  market to
owners of Pentium PCs.

Introduce New Generations of REALmagic, Offer REALmagic products at Competitive
Prices and Continually Reduce Product Costs

         A significant  aspect of the Company's  product strategy is to increase
the sale of REALmagic  chipsets  while  continuing to develop newer versions and
generations  of  REALmagic  products,  including  chipsets  for both desktop and
notebook PCs. The Company seeks to continue to offer  consumers  better-featured
and lower-priced products over time.
    

REALmagic Products

   
         The Company  currently  offers a complete family of REALmagic  products
including:

     o   REALmagic Hollywood Plus-In April 1997, the Company announced its entry
         into the DVD market. The REALmagic  Hollywood Plus MPEG-2 playback card
         turns a PC into a  full-featured  DVD player that  exploits many of the
         digital video and digital surround sound capabilities of the DVD format
         and upcoming MPEG-2 interactive  titles.  The REALmagic  Hollywood Plus
         DVD/MPEG-2  playback card displays  flicker-free  video at  full-screen
         resolution,  making video watching on a PC a new experience. Movies can
         be simultaneously displayed on the PC monitor and on a large-screen TV.

     o   REALmagic  NetStream 2-In October 1997, the Company announced its entry
         into the MPEG-2  networked  video  market.  Products  in the  NetStream
         family include specialized hardware and software developed specifically
         for  delivering  video to  corporate  desktops and can be used for both
         video on demand and broadcast video playback.  NetStream 2 is an MPEG-2
         playback   card   offering   full  plug  and  play   installation   and
         compatibility with a broad range of third-party applications, including
         video  servers  for  video on  demand,  MPEG  encoders  for  stored  or
         real-time  playback,   satellite  delivery  systems,   streaming  video
         playback  systems  and  scores  of  customizable  interactive  training
         titles.

     o   REALmagic  EM8300-In March 1998, the Company announced the introduction
         of the EM8300 REALmagic  DVD/MPEG-2/MPEG-1  decoder  Integrated Circuit
         ("IC").  Integrating  virtually  all  functions of a DVD decoder on one
         chip,  the  EM8300 is  designed  to provide a highly  integrated,  cost
         effective vehicle for high-quality DVD. The EM8300 feature set draws on
         Sigma's  industry-leading  experience  in the  DVD/MPEG-2  market  with



<PAGE>


         earlier designs such as the REALmagic  Ventura and REALmagic  Hollywood
         decoder cards.  The result is a blend of performance and  affordability
         that can be key to gaining  market  share in the  rapidly  growing  DVD
         market.

     o   REALmagic  EM8220  DVD/MPEG-2 VGA Add-On Card-In June 1998, the Company
         announced  the  introduction  of  a  daughter  card  to  add  to  Intel
         i740-based 2D/3D Video Graphics Array ("VGA") graphics cards to quickly
         and  effectively  deliver   high-performance,   video-ready  multimedia
         systems.

     o   REALmagic  DVD/MPEG-2  Notebook  Module-Designed to connect directly to
         the VGA controller through the ZV-bus and to the system bus through the
         module's  Peripheral  Component  Interconnect  ("PCI")  interface,  the
         notebook module gives notebook users all of the power and impact of DVD
         performance with their go-anywhere systems.

     o   REALmagic  EM8800-In  October 1998, the Company announced the REALmagic
         EM8800  decoder IC, the first  single-chip  PC solution for China's new
         Super Video Compact Disk ("SVCD") standard.  Integrating  virtually all
         SVCD  decoding  functions on one chip,  the EM8800 can turn a PC into a
         full-featured  home  theater  video  player  that  fully  exploits  the
         improved video quality supported by the SVCD standard.
    

Marketing and Sales

   
         Sigma  Designs  currently  distributes  its products  through  sales to
national and regional  distributors,  value-added resellers and OEMs in the U.S.
and throughout the world. The Company's U.S.  distributors include Ingram Micro,
Inc. and Tech Data, and its OEMs include Sony,  Philips,  Panasonic Canada,  IBM
Canada,  Matsushita,  Toshiba, Kapok Computers,  Sidus/TigerDirect,  Inc., Royal
Computer,  ASE Technologies,  LungHwa  Electronics Co., Ltd., Formosa Industrial
Computing,   Labway   Corporation  and  others.   The  Company's   international
distributors are strategically located in many countries around the world.

         The Company generally  acquires and maintains products for distribution
through  corporate  markets based on forecasts rather than firm purchase orders.
Additionally,  the  Company  generally  acquires  products  for  sale to its OEM
customers  only after  receiving  purchase  orders  from such  customers,  which
purchase orders are typically  cancellable without substantial penalty from such
OEM customers.  The Company currently places  noncancellable  orders to purchase
semiconductor products from its suppliers on a twelve- to sixteen-week lead time
basis.  Consequently,  if,  as a result of  inaccurate  forecasts  or  cancelled
purchase  orders,  anticipated  sales and  shipments in any quarter do not occur
when expected,  expenses and inventory levels could be disproportionately  high,
requiring  significant  working  capital and resulting in severe pressure on the
Company's financial condition.

         Sales to distributors  are typically  subject to contractual  rights of
inventory  rotation and price protection.  Regardless of particular  contractual
rights,  the failure of one or more  distributors  or



<PAGE>


OEMs to achieve  sustained  sell-through  of REALmagic  products could result in
product returns or collection problems, contributing to significant fluctuations
in the Company's operating results.
    

Research and Development

   
         As of November  30,  1998 the  Company  had a staff of 31 research  and
development  personnel.  The research and development  personnel conduct all the
Company's product  development.  The Company is focusing its development efforts
primarily on MPEG multimedia  products,  including new and improved  versions of
REALmagic MPEG chipsets and cost reduction processes.

         To achieve and  maintain  technological  leadership,  the Company  must
continue to make technological advancements in the areas of MPEG video and audio
compression  and   decompression.   These   advancements   include   maintaining
compatibility   with   emerging   standards  and  multiple   platforms,   making
improvements to the REALmagic  architecture,  and developing enhancements to the
REALmagic Application Programming Interface (API).
    

         There can be no  assurance  that the  Company  will be able to make any
such  advancements  in the REALmagic MPEG  technology or, if they are made, that
the Company will be able to market such  advancements to maintain  profitability
and its technological leadership.

   
         During fiscal 1998, fiscal 1997 and fiscal 1996, the Company's research
and   development   expenses  were   $4,948,000,   $4,688,000  and   $4,499,000,
respectively.  The Company plans to continue to devote substantial  resources to
research and  development  of future  generations  of MPEG and other  multimedia
products.
    

Competition

   
         The  market  for  MPEG  multimedia   products  is  highly  competitive;
companies  such as C-Cube  Microsystems  have a high  profile  in the  industry.
Although the Company  does not believe  that any products  sold by a third party
are in direct competition with the REALmagic decoding card in terms of price and
performance,  the  possibility  that other  companies  with more  marketing  and
financial  resources  may  develop a  competitive  product  may inhibit the wide
acceptance  of REALmagic  technology.  The Company  believes  that many computer
product  manufacturers  are developing MPEG products that will compete  directly
with REALmagic products in the near future.

         The Company  believes  that the  principal  competitive  factors in the
market for MPEG  multimedia  hardware  products  include  time to market for new
product   introductions,   product  performance,   compatibility  with  industry
standards,  price and marketing and distribution resources. The Company believes
that it  competes  most  favorably  with  respect  to time  to  market,  product
performance and price of its REALmagic products.  Moreover, the Company believes
that the  acceptance of the  REALmagic API as an industry  standard for software
development could provide a



<PAGE>


significant  competitive  advantage  for the Company.  However,  there can be no
assurance that the REALmagic API will be established as an industry  standard or
that the Company's lead time in product introduction will be sustained.

Licenses, Patents and Trademarks

         The  Company is seeking  patent  protection  for certain  software  and
hardware  features in current  and future  versions  of  REALmagic.  The Company
currently has fifteen pending patent applications for its REALmagic  technology.
Ten patents have been issued to the Company. There can be no assurance that more
patents  will be issued or that  such  patents,  even if  issued,  will  provide
adequate  protection for the Company's  competitive  position.  The Company also
attempts to protect its trade secrets and other proprietary  information through
agreements with customers,  suppliers and employees and other security measures.
Although the Company intends to protect its rights  vigorously,  there can be no
assurance that these measures will be successful.
    

Manufacturing

   
         To  reduce   overhead   expenses,   along  with  capital  and  staffing
requirements,  the Company currently uses third-party contract  manufacturers to
fulfill  all of its  manufacturing  needs,  including  chipset  manufacture  and
board-level  assembly.  All of the chips  used by the  Company  to  develop  its
decoding products are manufactured by outside  suppliers and foundries.  Each of
these  suppliers  is a sole  source of supply to the  Company of the  respective
chips produced by such supplier.
    

         The Company's reliance on independent suppliers involves several risks,
including  the absence of adequate  capacity and reduced  control over  delivery
schedules,  manufacturing  yields and costs.  Any delay or  interruption  in the
supply  of any of the  components  required  for  the  production  of  REALmagic
products  could have a  material  adverse  impact on the sales of the  Company's
products and, thus, on the Company's operating results.

       

Backlog

   
         Since the Company's  customers  typically expect quick deliveries,  the
Company  seeks to ship  products  within a few weeks of  receipt  of a  purchase
order.  However,  the customer may reschedule delivery of products or cancel the
purchase order entirely without significant penalty. Historically, the Company's
backlog has not been  reflective of future sales.  The Company also expects that
in the near term,  its  backlog  will  continue to be not  indicative  of future
sales.
    

Employees

   
         As of  November  30,  1998,  the Company  had 71  full-time  employees,
including 31 in research and development, 15 in marketing, sales and support, 10
in operations, and 15 in finance and administration.
    



<PAGE>


         The Company's  future  success will depend,  in part, on its ability to
continue to attract, retain and motivate highly qualified technical,  marketing,
engineering  and management  personnel,  who are in great demand.  The Company's
employees are not represented by any collective bargaining unit, and the Company
has never  experienced a work stoppage.  The Company  believes that its employee
relations are satisfactory.

       

                                 USE OF PROCEEDS

   
         The  Company  will not  receive  any  proceeds  from the sale of shares
hereunder by the Selling Shareholders.


                              SELLING SHAREHOLDERS

         On June 25, 1997,  the Company  entered into a  Subscription  Agreement
with Banque Edouard Constant SA and RIC Entity Limited,  pursuant to which those
two  entities  purchased  certain  shares of Series A  Preferred  Stock that are
convertible  into Common  Stock of the  Company  (the  "Preferred  Stock") in an
aggregate  amount  of  $4,500,000,  and,  concurrent  with the  purchase  of the
Preferred  Stock,  such entities also received  warrants to purchase  additional
Common  Stock at an  exercise  price in  excess of the  conversion  price of the
Preferred Stock. The original Registration  Statement No. 333-33147 was filed by
the Company  pursuant to the  exercise of certain  registration  rights  granted
under the Subscription Agreement. In addition, the Company granted 10,000 shares
of Common  Stock to Gene Jung on behalf of Trinity  Capital  Advisors,  Inc.  in
consideration for his efforts in assisting with the sale of the Preferred Stock.

         On March 11, 1998, the Company, Banque Edouard Constant SA ("BEC"), and
KA Investments  LDC entered into an Assignment and  Assumption  Agreement  under
which KA Investments  LDC purchased from BEC 15,000 shares of Series A Preferred
Stock  convertible  into  shares  of the  Company's  Common  Stock and a Warrant
exercisable for 21,428 shares of the Company's Common Stock (the "Warrant"). The
Series A Preferred  Stock and Warrant now held by KA Investments  LDC is subject
to the terms of the June 25,  1997  Subscription  Agreement,  a  Certificate  of
Determination  of Preferences  filed in connection with the initial  issuance of
the Preferred Stock, and a Registration Rights Agreement.

         In  accordance  with  the  Assignment  and  Assumption  Agreement,   KA
Investments LDC obtained certain  registration  rights relating to the shares of
Series  A  Preferred  Stock  and  the  Warrant  under  the  Registration  Rights
Agreement.

position or office or had a material relationship with the Company or any of its
affiliates within the past three years.

                              PLAN OF DISTRIBUTION

   
         The Selling  Shareholders may, from time to time, sell all or a portion
of the shares on the Nasdaq Stock Market in privately negotiated transactions or
otherwise,  at fixed prices that may be changed,  at market prices prevailing at
the time of sale,  at prices  related  to such  market  prices or at  negotiated
prices. The shares may be sold by The Selling Shareholders by one or more of the
following methods,  without limitation:  (a) block trades in which the broker or
dealer so engaged  will attempt to sell the shares as agent but may position and
resell a portion of the block as principal to facilitate  the  transaction,  (b)
purchases by a broker or dealer as principal and resale by such broker or dealer
for its account  pursuant to this  Prospectus,  (c) an exchange  distribution in
accordance with the rules of such exchange,  (d) ordinary brokerage transactions
and  transactions  in  which  the  broker  solicits  purchasers,  (e)  privately
negotiated  transactions,  (f) short sales,  and (g) a  combination  of any such
methods of sale. In effecting sales,  brokers and dealers engaged by the Selling
Shareholders may arrange for other brokers or dealers to participate. Brokers or
dealers may receive commissions or discounts from the Selling  Shareholders (or,
if any such broker-dealer  acts as agent for the purchaser of such shares,  from
such  purchaser)  in amounts to be  negotiated  which are not expected to exceed
those customary in the types of transactions involved.  Broker-dealers may agree
with the Selling  Shareholders  to sell a  specified  number of such shares at a
stipulated price per share,  and, to the extent such  broker-dealer is unable to
do so acting as agent for a Selling  Shareholder,  to purchase as principal  any
unsold shares at the price required to fulfill the  broker-dealer  commitment to
such Selling  Shareholder.  Broker-dealers  who acquire  shares as principal may
thereafter  resell  such  shares  from time to time in  transactions  (which may
involve  block  transactions  and  sales to and  through  other  broker-dealers,
including  transactions of the nature described  above) in the  over-the-counter
market or otherwise at prices and on terms then  prevailing at the time of sale,
at  prices  then  related  to the  then-current  market  price or in  negotiated
transactions  and, in connection  with such resales,  may pay to or receive from
the  purchasers  of such shares  commissions  as  described  above.  The Selling
Shareholders  may also  sell the  shares in  accordance  with Rule 144 under the
Securities Act, rather than pursuant to this Prospectus.

         The  Selling   Shareholders  and  any  broker-dealers  or  agents  that
participate  with the Selling  Shareholders in sales of the shares may be deemed
to be  "underwriters"  withing the meaning of the  Securities  Act in connection
with such sales. In such event, any commissions  received by such broker-dealers
or agents and any profit on the  resale of the shares  purchased  by them may be
deemed to be underwriting commissions or discounts under the Securities Act.



<PAGE>


         From time to time the Selling  Shareholders  may engage in short sales,
short sales against the box, puts and calls and other transactions in securities
of the Company or  derivatives  thereof,  and may sell and deliver the shares in
connection  therewith  or in  settlement  of  securities  loans.  If the Selling
Shareholders engage in such transactions,  the Conversion Price may be affected.
From time to time the Selling  Shareholders  may pledge their shares pursuant to
the margin  provisions of their customer  agreements with their brokers.  Upon a
default by a Selling  Shareholder,  the  broker  may offer and sell the  pledged
shares from time to time.

         The Company is required  to pay all fees and  expenses  incident to the
registration  of the shares,  including  one half of any fees and  disbursements
(which half is not to exceed an  aggregate  of $5,000) of counsel to the Selling
Shareholders.  The Company  has agreed to  indemnify  the  Selling  Shareholders
against certain losses, claims,  damages and liabilities,  including liabilities
under the Securities Act.

Item 15.   Indemnification of Directors and Officers

         Section 317 of the California  Corporations  Code authorizes a court to
award or a corporation's  Board of Directors to grant indemnity to directors and
officers  in terms  sufficiently  broad to  permit  such  indemnification  under
certain  circumstances  for liabilities  (including  reimbursement  for expenses
incurred)  arising  under the  Securities  Act.  Article IV of the  Registrant's
Second Restated  Articles of  Incorporation  and Article VI of the  Registrant's
Bylaws provide for  indemnification  of its directors,  officers,  employees and
other  agents to the maximum  extent  permitted by the  California  Corporations
Code. In addition,  the Registrant has entered into  Indemnification  Agreements
with its officers and directors.

   
         Insofar as indemnification for liabilities arising under the Securities
Act  may  be  permitted  to  directors,  officers  or  persons  controlling  the
Registrant pursuant o the foregoing provisions, the Registrant has been informed
that  in  the  opinion  of  the   Securities  and  Exchange   Commission,   such
indemnification  is against public policy as expressed in the Securities Act and
is therefore unenforceable.

Item 17.   Undertakings

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

         The undersigned Registrant hereby undertakes:

         (1) To file, during any period in which offers or sales are being made,

material  information  with respect to the plan of  distribution  not previously
disclosed  in  the  Registration  Statement  or  any  material  change  to  such
information in the Registration Statement.

   
         (2)  That,  for the  purpose  of  determining  any  ability  under  the
Securities Act, each such  post-effective  amendment 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.
    

         (3) To remove from registration by means of a post-effective  amendment
any of the securities being registered which remain unsold at the termination of
the offering.

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

                       ASSIGNMENT AND ASSUMPTION AGREEMENT


         ASSIGNMENT AND ASSUMPTION  AGREEMENT  (this  "Agreement"),  dated as of
March 11, 1998, among Banque Edouard Constant, a Swiss corporation ("Assignor"),
KA  Investments  LDC,  a Cayman  Islands  corporation  ("Assignee"),  and  Sigma
Designs, Inc., a California corporation (the "Company").

         WHEREAS,  the Company and Assignor entered into a certain  Subscription
Agreement  (the  "Subscription  Agreement";   capitalized  terms  used  and  not
otherwise  defined  herein shall have the  respective  meanings set forth in the
Subscription Agreement), dated as of June 25, 1997;

         WHEREAS,  in  connection  with  the  transactions  contemplated  by the
Subscription  Agreement,  the Company  delivered  to Assignor  40,000  shares of
Series A Preferred  Stock (the  "Shares")  and a common stock  purchase  warrant
pursuant to which the Assignor is currently entitled to acquire 57,142 shares of
Common  Stock of the  Company  at an  exercise  price of  $9.425,  as set  forth
thereunder (the  "Warrant")  (the shares of Common Stock  underlying the Warrant
are referred to as the "Warrant Shares");

         WHEREAS,  the  Assignor  wishes to hereby  sell,  transfer,  convey and
assign to the Assignee its right, title and interest in 15,000 Shares (the "Sold
Shares") and 21,428 Warrant Shares (the "Sold Warrants,"  together with the Sold
Shares,  the  "Securities")  and to retain its right,  title and interest in the
remaining 8,000 Shares and the remaining 35,714 Warrant Shares;

         WHEREAS,  in  connection  with  the  transactions  contemplated  by the
Subscription  Agreement,  the Company granted the Assignor certain  registration

1997, the Company filed a registration statement on Form S-3 with the Securities
and Exchange Commission (the "SEC") covering the resale of the Underlying Shares
and Warrant Shares (the  "Registration  Statement")  and, in connection with the
closing of the transactions  contemplated hereunder, the Company will file a new
registration  statement (the "New Registration  Statement") in order to register
an  additional  900,000  shares of  Common  Stock  pursuant  to the terms of the
Registration Rights Agreement (the "Additional  Registrable  Securities") and to
include the  Assignee as a selling  shareholder  thereunder  with respect to its
Underlying Shares and Warrant Shares (the "Assignee's Underlying Share"); and

         WHEREAS,   the  Company  has  agreed  to  permit  the  sale,  transfer,
conveyance and assignment of the Securities, subject to the terms and conditions
set forth below.

                                       -1-

         NOW,  THEREFORE,  in  consideration  of the  promises and of the mutual
covenants  herein set forth and for other good and valuable  consideration,  the
receipt of which is hereby acknowledged, the parties hereto agree as follows:

         1.  Assignment of the  Securities.  Subject to the terms and conditions
set forth in this Agreement and the Escrow Agreement among the Company, Assignor
and  Assignee,  dated the date hereof (the  "Escrow  Agreement"),  the  Assignor
hereby sells,  transfers,  conveys and assigns to Assignee the  Securities,  the
Assignee accepts such sale, transfer, conveyance and assignment in reliance upon
the  Assignor's  representations  and warranties set forth in Schedule A and the
Company's representations and warranties set forth in Schedule B and the Company
agrees  to  permit  such  sale,  transfer,  conveyance  and  assignment  of  the
Securities in reliance upon the  Assignee's  representations  and warranties set
forth in Schedule C.

         2.  Purchase  Price.  The purchase  price for the  Securities  shall be
$1,500,000 (the "Purchase Price").

         3. Filing of the New Registration  Statement.  The Company acknowledges
and  confirms   that  within  five  (5)  business  days  of  its  receipt  of  a
fully-executed  copy of this Agreement (the "Filing Date"), it will file the New
Registration Statement to include the Additional Registrable Securities and name
the Assignee as a selling shareholder  thereunder with respect to the Assignee's
Underlying Shares, provided, however, that not less than three (3) business days
prior to the Filing Date,  the Company shall (i) furnish to the Assignee and its
counsel,  copies of all such documents  proposed to be filed in connection  with
the New Registration  Statement,  which documents (other than those incorporated
or deemed to be  incorporated by reference) will be subject to the review of the
Assignee and its counsel, and (ii) cause its officers and directors, counsel and
independent  certified public  accountants to respond to such inquiries as shall
be necessary, in the opinion of respective counsel to the Assignee, to conduct a
reasonable  investigation  within the meaning of the Securities Act. The Company
shall not file the New  Registration  Statement if the Assignee is reviewing the
New  Registration  Statement  and shall  reasonably  object  on a timely  basis.
Notwithstanding  anything to the contrary  contained  herein,  in the event that
either (i) the Company and the  Assignee  are unable to agree on the language to
be  used in the  New  Registration  Statement,  or  (ii)  the  New  Registration
Statement has not been filed with the SEC by the Filing Date, the Assignee shall
have the right to  terminate  this  Agreement  at any time after the Filing Date
(the "Assignee's Termination Right").

         4. Closing of the Sale of the Securities.

                  (a) The closing for the sale of the Securities (the "Closing")
shall, subject to the terms of the Escrow Agreement, take place two (2) business
days following the date on which the Escrow Agent has received a copy of the New
Registration  Statement,  together  with proof  reasonably  satisfactory  to the
Assignee that such New Registration Statement has been filed with the SEC.

                                       -2-

<PAGE>


                  (b) At the Closing,  the Escrow Agent,  in accordance with and
subject to the terms and conditions of the Escrow  Agreement,  shall deliver (i)
to the Assignee,  (x) a copy of the New  Registration  Statement  which has been
filed with the SEC, (y) now stock  certificate(s)  registered in the name of the
Assignee  reflecting the ownership of 15,000 shares of Series A Preferred  Stock
by the Assignee,  and (z) a new common stock purchase warrant  registered in the
name of the Assignee  (the  "Assignee  Warrant") in the form of the Warrant,  to
acquire 21,428 shares of Common Stock,  which Assignee Warrant shall contain the
same  terms as the  Warrant,  except  that the  exercise  price of the  Assignee
Warrant  shall be 130% of the average  closing bid price of the Common Stock for
the five days trading days  immediately  preceding May 1, 1998,  provided,  that
such  exercise  price shall not exceed  $9.425,  (ii) to the  Assignor,  (x) the
Purchase Price,  and (y) a new common stock purchase  warrant  registered in the
name of the Assignor (the "Assignor  Warrant"),  in the form of the Warrant,  to
acquire 35,714 shares of Common Stock,  which Assignor Warrant shall contain the
same terms as the  Assignee  Warrant,  (iii) to the  Company,  the old  warrant,
representing  the Warrant,  previously  delivered to the Assignor in  connection
with the Subscription  Agreement,  and (iv) to the party entitled  thereto,  all
other  documents,  instruments  and  writings,  if any,  required  to have  been
delivered  at or prior to such  Closing  by any party  hereto  pursuant  to this
Agreement or the Escrow Agreement.

         5.       Certain Agreements of the Company.

                  (a)  The  Company  acknowledges  and  confirms  that  (i)  the
Assignee is an intended  beneficiary hereof and shall be entitled to enforce all
of the rights and benefits of a Purchaser under the Purchase  Agreement as if it
were a party thereto, and (ii) the Assignee's  Underlying Shares shall be deemed
to  be  "Registrable   Securities"  (as  defined  in  the  Registration   Rights
Agreement),  and that the Assignee shall have the same registration  rights with
respect to the Assignee's  Underlying Shares as all other owners of "Registrable
Securities" have under the  Registration  Rights Agreement as if it were a party
thereto.

                  (b) The  Company  acknowledges  and  confirms  that if the New
Registration  Statement is not declared  effective by the SEC on or prior to the
60th day  following  the date of the  Closing  (the  "Effectiveness  Date")  the
Company  shall  pay  to  the  Assignee  $15,000  on the  Effectiveness  Date  as
liquidated  damages and not as a penalty.  Thereafter,  the Company shall pay to
the  Assignee,  as  liquidated  damages  and not as a  penalty,  $45,000 on each
monthly   anniversary   following  the  Effectiveness  Date  in  which  the  New
Registration  Statement  has  not  been  declared  effective  by  the  SEC.  The
Effectiveness  Date will be extended,  as applicable,  by the number of days, in
excess of two (2), during which the proposed registration statement was reviewed
by the Assignee and its counsel pursuant to Section 3 hereof.

                  (c) At the  Closing,  the Company  shall pay one half (1/2) of
the legal fees and  expenses of the  Assignee  incident to the  preparation  and
negotiation  of  documents  relating to the  transactions  contemplated  by this
Agreement, up to a maximum of $5,000.

                                       -3-

<PAGE>


                  (d) At the Closing,  the Company agrees to pay to the Assignor
accrued and unpaid  dividends up to and  including the date of the Closing and a
special  payment  of 1.5% of the  aggregate  Original  Issue  Price  of the Sold
Shares.

                  (e) The  Assignee  and the Company  agree that the  Assignee's
right to receive dividends on the Sold Shares shall begin on the day immediately
following the Closing.

         6.       Certain Agreements of the Assignee.

                  (a) The Assignee agrees that it will not exercise its right to
convert the Sold Shares into shares of Common  Stock prior to 90 days  following
the date of the Closing.

                  (b)  The  Assignee  agrees  further  that  until  the  day the
Assignee  validly  exercises its right to convert the Sold Shares into shares of
Common Stock (the  "Lock-up  Period"),  it will not,  without the express  prior
written  consent of the  Company,  offer,  sell,  make any short sale of,  loan,
encumber,  grant any option for the purchase of, or  otherwise,  dispose of (the
"Resale  Restrictions"),  any  securities of the Company  beneficially  owned or
otherwise  held by the Assignee as of the date hereof or  hereafter  acquired by
the Assignee (collectively,  the "Restricted Securities").  The foregoing Resale
Restrictions  are  expressly  agreed to  preclude  the holder of the  Restricted
Securities from engaging in any hedging or other  transaction  which may lead to
or result in a sale of Restricted  Securities during the Lock-up Period, even if
such  Restricted  Securities  would be sold by someone  other than the Assignee.
Such prohibited hedging or other transactions would include, without limitation,
any short sale  (whether or not against  the box),  any pledge or any  purchase,
sale or grant  of any  right  (including,  without  limitation,  any put or call
option)  with  respect  to  any  of  the  Restricted   Securities.   The  Resale
Restrictions  shall not apply to the  conversion  of the Sold Shares into Common
Stock as  contemplated  by this  Agreement  but shall apply to the Common  Stock
issued upon such  conversion.  The Assignee  agrees and consents to the entry of
stop transfer  instructions  with the transfer  agent for the  Company's  Common
Stock  against any  transfer  of shares of Common  Stock by the  undersigned  in
contravention of the Resale Restrictions.

                  (c) The  Assignee  agrees not to  effectuate  or cause a third
party to effectuate a sale of, offer for sale, or solicit a purchase or offer to
purchase  the Common  Stock with the  intention  of causing a  reduction  in the
Conversion Price.

         7.       Miscellaneous.

                  (a)  Authority.  Each of the  Company,  the  Assignor  and the
Assignee  hereby  represent and warrant to the other that each has the requisite
power  and  authority  to  enter  into  and  to  consummate   the   transactions
contemplated  by  this  Agreement,  that  the  execution  and  delivery  of this
Agreement and the  transactions  contemplated  by this  Agreement have been duly
authorized  by all  necessary  action,  that  this  Agreement  has been  validly
executed and delivered, and that this Agreement constitutes its valid, legal and
binding obligation,  enforceable against it in accordance with its terms, except
as such enforceability may be limited by applicable bankruptcy, insolvency,

reorganization,   moratorium,  liquidation  or  similar  laws  relating  to,  or
affecting  generally the  enforcement of,  creditors'  rights and remedies or by
other equitable principles of general application.

                  (b) Further  Assurances.  The parties  hereto agree to execute
such other documents and instruments as may be reasonably required to effectuate
the sale, transfer, conveyance and assignment contemplated by this Agreement.

                  (c) Amendment and Modification. This Agreement may be amended,
modified and supplemented  only in a written  agreement  executed by each of the
parties hereto.

                  (d) Successors and Assigns.  This Agreement shall inure to the
benefit of and be binding upon the respective  successors and permitted  assigns
of the parties hereto.  Assignment of the rights and obligations hereunder shall
be governed by the terms thereof set forth in the Registration Rights Agreement.
The  assignment by a party of this Agreement or any rights  hereunder  shall not
affect the obligations of such party under this Agreement.

                  (e)  Governing  Law. This  Agreement  shall be governed by and
construed in accordance  with the internal laws of the State of New York without
regard to conflicts of law principals thereof.

                  (f) Counterpart Signatures;  Facsimile.  This Agreement may be
executed in  counterparts,  which will, when taken  together,  be deemed for all
purposes  to be one and  the  same  Agreement.  For all  purposes,  a  signature
delivered by  facsimile  shall have the same force and effect as the original of
such signature.

         3.       Duties and Obligations of the Escrow Agent.

                  (a) The parties  hereto agree that the duties and  obligations
of the Escrow  Agent are only such as are herein  specifically  provided  and no
other.  The Escrow Agent's duties are as a depositary only, and the Escrow Agent
shall incur no liability  whatsoever,  except as a direct  result of its willful
misconduct.

                  (b) The Escrow  Agent may consult  with counsel of its choice,
and shall not be liable  for any  action  taken,  suffered  or  omitted by it in
accordance with the advice of such counsel.

                  (c) The  Escrow  Agent  shall  not be  bound in any way by the
terms of any other agreement to which the Company, the Assignee and the Assignor
are parties, whether or not it has knowledge thereof, and the Escrow Agent shall
not in any way be required to determine  whether or not any other  agreement has
been complied with by the Company,  the Assignee and the Assignor,  or any other
party  thereto.  The  Escrow  Agent  shall  not be  bound  by any  modification,
amendment,  termination,   cancellation,  rescission  or  supersession  of  this
Agreement unless the same shall be in writing and signed by each of the Company,
the Assignee and the Assignor, and agreed to in writing by the Escrow Agent.

                  (d) In the event that the Escrow  Agent shall be  uncertain as
to its  duties or rights  hereunder  or shall  receive  instructions,  claims or
demands  which,  in its opinion,  are in conflict with any of the  provisions of
this  Agreement,  it shall be entitled to refrain from taking any action,  other
than to keep  safely  all  Consideration  then  held in  escrow,  until it shall
jointly be directed  otherwise in writing by the Assignee and the Assignor or by
a final judgment of a court of competent jurisdiction.

                  (e) The Escrow Agent shall be fully  protected in relying upon
any written  notice,  demand,  certificate  or document which it, in good faith,
believes  to be  genuine.  The Escrow  Agent  shall not be  responsible  for the
sufficiency  or accuracy of the form,  execution,  validity  or  genuineness  of
documents  or  securities  now  or  hereafter  deposited  hereunder,  or of  any
endorsement  thereon,  or for  any  lack  of  endorsement  thereon,  or for  any
description  therein; nor shall the Escrow Agent be responsible or liable in any
respect on account of the identity, authority or rights of the persons executing
or delivering or purporting to execute or deliver any such document, security or
endorsement.

                  (f) The Escrow Agent shall not be required to institute  legal
proceedings  of any  kind  and  shall  not  be  required  to  defend  any  legal
proceedings   which  may  be  instituted   against  it  or  in  respect  of  the
Consideration.

                  (g) If the Escrow Agent at any time,  in its sole  discretion,
deems it necessary or advisable to relinquish  custody of the Consideration then
held by it,  it may do so by  delivering  the  same to any  other  escrow  agent
mutually agreeable to the Assignee and the Assignor and, if no such escrow agent
shall be selected  within three days of the Escrow Agent's  notification  to the
Assignee  and  the  Assignor  of its  desire  to so  relinquish  custody  of the
Consideration  then held by it,  then the Escrow  Agent may do so by  delivering
such Consideration (a) to any bank or trust company in the

                                       -4-

escrow agent  thereunder in place and instead of the Escrow Agent, or (b) to the
clerk or other  proper  officer of a court of competent  jurisdiction  as may be
permitted by law within the State,  County and City of New York.  The fee of any
such bank or trust company or court officer shall be borne by the Assignor. Upon
such  delivery,   the  Escrow  Agent  shall  be  discharged  from  any  and  all
responsibility  or liability with respect to the  Consideration and the Assignor
shall  promptly  pay to the Escrow Agent all monies which may be owed it for its
services  hereunder,  including,  but  not  limited  to,  reimbursement  of  its
out-of-pocket expenses pursuant to paragraph (i) below.

                  (h) This Agreement  shall not create any fiduciary duty on the
Escrow Agent's part to the Company, the Assignee or the Assignor, nor disqualify
the Escrow Agent from  representing  either party hereto in any dispute with the
other, including any dispute with respect to the Consideration.  The Company and
the  Assignor  understand  that  RSPA&B  has acted and will  continue  to act as
counsel to Assignor.

                  (i) The reasonable  out-of-pocket expenses paid or incurred by
the Escrow Agent in the administration of its duties hereunder,  including,  but
not  limited to, all counsel  and  advisors'  and agents'  fees and all taxes or
other governmental charges, if any, shall be paid by the Assignor.

         4. Indemnification. The Company, the Assignee and the Assignor, jointly
and  severally,  hereby  indemnify  and hold the Escrow Agent  harmless from and
against any and all losses, damages, taxes, liabilities and expenses that may be
incurred,  directly or  indirectly,  by the Escrow  Agent,  arising out of or in
connection  with its  acceptance of  appointment  as the Escrow Agent  hereunder
and/or the performance of its duties pursuant to this Agreement,  including, but

performance  hereunder  and the costs of  recovery  of amounts  pursuant to this
Section 4.

         2. Exercise or Exchange of Warrant.

                  (a) This Warrant may be exercised  by the Warrant  Holder,  in
whole or in part,  at any time  during  the life of this  Warrant  as  described
herein,  and from time to time by surrender of this  Warrant,  together with the
Exercise  Form (as defined  herein) at the end hereof  duly  executed by Warrant
Holder, together with the full Purchase Price (as defined in Section 1) for each
share of Common  Stock as to which this  Warrant is  exercised to the Company at
the address of the Company set forth in Section 13 hereof. In the event that the
Warrant is not exercised in full,  the number of Warrant Shares shall be reduced
by the number of such Warrant  Shares for which this Warrant is  exercised,  and
the Company,  at its expense,  shall  forthwith issue and deliver to or upon the
order of the  Warrant  Holder  a new  Warrant  of like  tenor in the name of the
Warrant  Holder or as the Warrant Holder may request,  reflecting  such adjusted
Warrant Shares.  Warrants may be exchanged for shares of Common Stock, the value

admitted to trading on any national  securities exchange or quoted on the Nasdaq
National Market or Small-Cap Market or traded  over-the-counter  and the average
price cannot be determined as contemplated  above,  the fair market value of the
Common Stock as reasonably  determined  in good faith by the Company's  Board of
Directors.

that the advance copy of the form of exercise  attached hereto as Exhibit A (the
"Exercise  Form"),  is sent by  facsimile  to the  Company,  provided  that  the
original Warrant and Exercise Form are received by the Company within reasonable
time thereafter. If the Warrant Holder has not sent advance notice by facsimile,
the Date of Exercise shall be the date the original Exercise Form is received by
the Company.

         3. Delivery of Stock Certificates.

                  (a) Subject to the terms and  conditions of this  Warrant,  as
soon as  practicable  after the exercise of this Warrant in full or in part, and
in any event  within  five (5)  business  days  thereafter,  the  Company at its
expense  (including,  without  limitation,  the payment by it of any  applicable
issue taxes) will cause to be issued in the name of and delivered to the Warrant
Holder,  or as  the  Warrant  Holder  may  lawfully  direct,  a  certificate  or
certificates  for the number of fully paid and  non-assessable  shares of Common
Stock to which the Warrant Holder shall be entitled on such  exercise,  together
with any other stock or other  securities  or property  (including  cash,  where
applicable)  to which the  Warrant  Holder is  entitled  upon such  exercise  in
accordance with the provisions hereof.

                  (b) This Warrant may not be exercised as to fractional  shares
of Common Stock.  In the event that the exercise of this Warrant,  in full or in
part, would result in the issuance of any fractional share of Common Stock, then
in such event the  Warrant  Holder  shall be  entitled to cash equal to the fair
market  value of such  fractional  share.  For purposes of this  Warrant,  "fair
market  value"  shall  equal the  closing  bid price of the Common  Stock on the
Nasdaq National Market or Small-Cap  Market,  the American Stock Exchange or the
New York Stock Exchange,  whichever is the principal  trading exchange or market
for the Common Stock (the "Principal  Market") on the date of determination  or,
if the  Common  Stock is not  listed or  admitted  to  trading  on any  national
securities exchange or quoted on the Nasdaq National Market or Small-Cap Market,
the closing bid price on the  over-the-counter  market as  furnished  by any New
York  Stock  Exchange  member  firm  which  makes a market in the  Common  Stock
reasonably  selected from time to time by the Company for that  purpose,  or, if
the Common Stock is not listed or admitted to trading on any national securities
exchange or quoted on the Nasdaq National  Market or Small-Cap  Market or traded
over-the-counter  and the average  price cannot be  determined  as  contemplated
above,  the  fair  market  value of the  Common  Stock  shall  be as  reasonably
determined in good faith by the Company's Board of Directors.

         4. Covenants of the Company.

                  (a) The  Company  shall use its  reasonable  best  efforts  to
insure that a  registration  statement  under the  Securities  Act  covering the
resale or other disposition  thereof of the Warrant Shares by the Warrant Holder
is effective to the extent provided by the Registration Rights Agreement.

                  (b) All Warrant Shares that may be issued upon the exercise of
the rights  represented by this Warrant will, upon issuance,  be validly issued,
fully paid and  nonassessable  and free from all taxes,  liens, and charges with
respect to the issue thereof.

                  (c)  The  Company   shall  take  all   necessary   action  and
proceedings  as may be  required  and  permitted  by  applicable  law,  rule and
regulation,  including,  without  limitation  the  notification  of  the  Nasdaq
National  Market,  for the legal  and valid  issuance  of this  Warrant  and the
Warrant Shares to the Warrant Holder.

<PAGE>


                  (d) From the date  hereof  through the last date on which this
Warrant is exercisable,  the Company shall take all steps  reasonably  necessary
and within its control to insure that the Common Stock remains  listed or quoted
on the Principal Market.

                  (e) The Company shall at all times reserve and keep available,
solely for  issuance and delivery as Warrant  Shares  hereunder,  such shares of
Common Stock as shall from time to time be issuable as Warrant Shares.

                  (f) The Warrant  Shares,  when issued in  accordance  with the
terms hereof, will be duly authorized and, when paid for or issued in accordance
with the terms hereof,  shall be validly issued,  fully paid and non-assessable.
The Company has  authorized  and reserved for issuance to the Warrant Holder the
requisite  number  of  shares of  Common  Stock to be  issued  pursuant  to this
Warrant.

                  (g) With a view to making  available to the Warrant Holder the
benefits of any rule or regulation  of the  Securities  and Exchange  Commission
(the "SEC"),  that may at any time permit the Warrant Holder to sell  securities
of the Company to the public without registration,  including without limitation
Rule 144, the Company agrees to use its reasonable  best efforts to (i) make and
keep public information available,  as those terms are understood and defined in
such rule or  regulation,  at all times;  and (ii) file with the SEC in a timely
manner  all  reports  and other  documents  required  of the  Company  under the
Securities Act and the Exchange Act.

                  (h) This Warrant will be binding upon any entity succeeding to
the Company by merger,  consolidation or acquisition of all or substantially all
of the Company's assets.

         5. Adjustment of Purchase Price and Number of Shares. The number of and
kind of  securities  purchasable  upon exercise of this Warrant and the Purchase
Price shall be subject to adjustment from time to time as follows:

                  (a)  Subdivisions,  Combinations and Other  Issuances.  If the
Company  shall at any time after the date hereof but prior to the  expiration of
this Warrant  subdivide its  outstanding  securities as to which purchase rights
under this Warrant exist, by split-up, or otherwise,  or combine its outstanding
securities as to which purchase  rights under this Warrant exist,  the number of
Warrant  Shares as to which this Warrant is  exercisable  as of the date of such
subdivision,   split-up,  or  combination  shall  forthwith  be  proportionately
increased in the case of a subdivision, or proportionately decreased in the case
of a  combination.  Appropriate  adjustments  shall also be made to the Purchase
Price,  so that after such  adjustments  the  aggregate  Purchase  Price payable
hereunder for the  increased  number of shares of Common Stock shall be the same
as the aggregate Purchase Price in effect immediately prior to such adjustments.

                  (b) Stock  Dividend.  If at any time after the date hereof the
Company  declares a dividend or other  distribution  on Common Stock  payable in
Common Stock or other securities or rights  convertible into or exchangeable for
Common Stock ("Common Stock Equivalents"),  without payment of any consideration
by holders of Common Stock for the additional shares of Common Stock or the

                                       -4-

<PAGE>


Common  Stock  Equivalents  (including  the  additional  shares of Common  Stock
issuable  upon  exercise or  conversion  thereof),  then the number of shares of
Common Stock for which this  Warrant may be  exercised  shall be increased as of
the record date (or the date of such dividend  distribution if no record date is
set) for determining  which holders of Common Stock shall be entitled to receive
such  dividends,  in  proportion  to the  increase in the number of  outstanding
shares (and shares of Common Stock  issuable upon  conversion of all such Common
Stock  Equivalents)  of  Common  Stock as a  result  of such  dividend,  and the
Purchase  Price shall be adjusted so that the aggregate  amount  payable for the
purchase of all the Warrant  Shares  issuable  hereunder  immediately  after the
record  date  (or on the  date of such  distribution,  if  applicable)  for such
dividend shall equal the aggregate  amount so payable before the record date (or
before the date of such distribution, if applicable).

                  (c) Other Distributions.  If at any time after the date hereof
the Company  distributes to holders of its Common Stock, other than as part of a
dissolution or  liquidation or the winding up of its affairs,  any shares of its
capital  stock,  any evidence of  indebtedness  or any of its assets (other than
cash,  Common Stock or Common Stock  Equivalents),  then, in any such case,  the
Warrant Holder shall be entitled to receive, upon exercise of this Warrant, with
respect to each  share of Common  Stock  issuable  upon such  exercise,  (i) the
amount of evidences of  indebtedness  or other  securities or assets  (excluding
cash and the Company's own Common Stock or Common Stock  Equivalents) which such
Warrant  Holder would have been entitled to receive as a result of the happening
of such event with  respect to each such share of Common  Stock  subject to this
Warrant had this Warrant been exercised  immediately prior to the record date or
other  date  determining  the  shareholders  entitled  to  participate  in  such
distribution (the "Determination Date") or (ii) in lieu thereof, if the Board of
Directors of the Company should so determine at the time of such distribution, a
lower Purchase Price reduced by the value of such distribution applicable to one
share  of  Common  Stock  (such  value  to be  determined  in good  faith by the
Company's Board of Directors).

                  (d) Merger, Consolidation,  etc. If at any time after the date
hereof there shall be a merger or  consolidation of the Company with or into, or
a transfer of all or substantially  all of the assets of the Company to, another
entity (a "Consolidation  Event"),  then the Warrant Holder shall be entitled to
receive upon such transfer, merger or consolidation becoming effective, and upon
payment of the aggregate  Purchase Price then in effect, the number of shares or
other securities or property of or cash or other  consideration from the Company
or of the successor corporation resulting from such merger or consolidation,  to
which such Warrant Holder would have been entitled to receive as a result of the
happening of such event with respect to each such share of Common Stock  subject
to this  Warrant  had this  Warrant  been  exercised  immediately  prior to such
transfer, merger or consolidation becoming effective or to the applicable record
date thereof, as the case may be. The Company shall not effect any Consolidation
Event unless the  resulting  successor or acquiring  entity (if not the Company)
assumes by written  instrument  the  obligation to deliver to the Warrant Holder
such shares of stock  and/or  securities  as the  Warrant  Holder is entitled to
receive had this  Warrant  been  exercised  in  accordance  with the  foregoing;
provided,  however,  that  if  as  of  the  third  business  day  prior  to  the
consummation  of the  Consolidation  Event the  closing  bid price of the Common
Stock shall be equal to at least 200% of the  Purchase  Price,  then the Warrant
shall  be   automatically   exchanged  on  the  date  of   consummation  of  the
Consolidation Event, as provided in Section 2 hereof.

<PAGE>


                  (e)  Reclassification,  Etc.  If at any  time  after  the date
hereof there shall be a reclassification  of any securities as to which purchase
rights  under  this  Warrant  exist,  into the  same or a  different  number  of
securities  of any  other  class or  classes,  then  the  Warrant  Holder  shall
thereafter  be entitled to receive  upon  exercise of this  Warrant,  during the
period  specified  herein and upon payment of the Purchase Price then in effect,
the  number  of  shares  or  other  securities  or  property  or cash  or  other
consideration  resulting from such  reorganization  or  reclassification,  which
would have been  received by the Warrant  Holder for the shares of stock subject
to this Warrant had this Warrant at such time been exercised.

                  (f) Purchase Price  Adjustment.  In the event that the Company
issues or sells any Common Stock or  securities  which are  convertible  into or
exchangeable for its Common Stock or any convertible securities, or any warrants
or other rights to subscribe  for or to purchase or any options for the purchase
of its Common Stock or any such convertible  securities  (other than issuance of
Preferred Stock or of shares of Common Stock upon conversion thereof,  shares or
options  issued or which may be issued to  employees,  directors or  consultants
pursuant to the  Company's  stock option or stock  purchase  plans listed in the
Public  Documents or shares issued upon exercise of options,  warrants or rights
outstanding on the date of the Agreement and listed in the Public  Documents) at
an effective purchase price per share which is less than the Purchase Price then
in effect and less than the fair market  value (as  hereinabove  defined) of the
Common Stock on the trading day next preceding such issue or sale,  then in each
such case, the Purchase Price in effect  immediately prior to such issue or sale
shall be  reduced  effective  concurrently  with such issue or sale to an amount
determined by multiplying  the Purchase Price then in effect by a fraction,  (x)
the  numerator  of which  shall be the sum of (1) the number of shares of Common
Stock outstanding  immediately prior to such issue or sale,  including,  without
duplication,  those  deemed  to have been  issued  under  any  provision  of the
Preferred  Stock and the Warrants  plus (2) the number of shares of Common Stock
which the aggregate  consideration  received by the Company for such  additional
shares  would  purchase  at such fair  market  value  then in effect and (y) the
denominator  of which  shall be the  number of  shares  of  Common  Stock of the
Company  outstand ing immediately  after such issue or sale  including,  without
duplication,  those  deemed  to have been  issued  under  any  provision  of the
Preferred Stock and Warrants;  provided, however, there shall be no reduction of
the  Purchase  Price for such  issuances or sales at any time from June 25, 1997
through the term of this Warrant in an  aggregate  (i.e.,  not per  transaction)
amount of up to  $4,500,000  provided that such issuance or sale is completed at
an effective  purchase  price per share of at least 85% of the fair market value
of the Common Stock on the trading day next  preceding  such issue or sale.  For
purposes of the foregoing  fraction,  Common Stock  outstanding  shall  include,
without limitation, any equity offer ings then outstanding,  whether or not they
are exercisable or convertible when such fraction is to be determined.

         The  number  of  shares  which  may be  purchased  hereunder  shall  be
increased  proportionately  to any reduction in Purchase  Price pursuant to this
paragraph  5(f), so that after such  adjustments  the aggregate  Purchase  Price
payable  hereunder for the  increased  number of shares of Common Stock shall be
the same as the aggregate  Purchase  Price in effect  immediately  prior to such
adjustments.

                                       -6-

<PAGE>


         Notwithstanding   anything  else  contained  in  this  Warrant  to  the
contrary,  there shall be no adjustment  of the Purchase  Price or the number of
shares of Common Stock issuable  pursuant to the exercise of this Warrant in the
event that during the term of this Warrant,  the Company issues shares of Common
Stock, or securities convertible into Common Stock to the Buyer.

                  (g) Adjustments:  Additional Shares,  Securities or Assets. In
the event that at any time, as a result of an  adjustment  made pursuant to this
Section 5, the Warrant  Holder  shall,  upon  exercise of this  Warrant,  become
entitled to receive shares and/or other  securities or assets (other than Common
Stock) then,  wherever  appropriate,  all references  herein to shares of Common
Stock  shall  be  deemed  to refer  to and  include  such  shares  and/or  other
securities  or assets;  and  thereafter  the number of such shares  and/or other
securities  or assets  shall be  subject  to  adjustment  from time to time in a
manner and upon terms as nearly  equivalent as  practicable to the provisions of
this Section 5.

         6. No Impairment. The Company will not, by amendment of its Articles of
Incorporation or through any reorganization,  transfer of assets, consolidation,
merger, dissolution,  issue or sale of securities or any other voluntary action,
avoid or seek to avoid the observance or performance of any of the terms of this
Warrant,  but will at all times in good faith  assist in the carrying out of all
such  terms  and in the  taking  of  all  such  action  as may be  necessary  or
appropriate  in order to  protect  the  rights  of the  Warrant  Holder  against
impairment.  Without  limiting the generality of the foregoing,  the Company (a)
will not increase the par value of any Warrant  Shares above the amount  payable
therefor  on  such  exercise,  and (b)  will  take  all  such  action  as may be
reasonably  necessary or  appropriate  in order that the Company may validly and
legally  issue fully paid and  nonassessable  Warrant  Shares on the exercise of
this Warrant.

         7. Notice of  Adjustments;  Notices.  Whenever  the  Purchase  Price or
number of Warrant Shares  purchasable  hereunder  shall be adjusted  pursuant to
Section 5 hereof,  the Company shall promptly execute and deliver to the Warrant
Holder a certificate  setting forth, in reasonable  detail,  the event requiring
the  adjustment,  the  amount  of the  adjustment,  the  method  by  which  such
adjustment   was  calculated  and  the  Purchase  Price  and  number  of  shares
purchasable hereunder after giving effect to such adjustment,  and shall cause a
copy of such certificate to be mailed (by first class mail,  postage prepaid) to
the Warrant Holder.

         8.  Rights As  Stockholder.  Prior to  exercise  of this  Warrant,  the
Warrant  Holder  shall not be  entitled  to any rights as a  stockholder  of the
Company with respect to the Warrant Shares,  including (without  limitation) the
right to vote such shares,  receive dividends or other distributions  thereon or
be notified of stockholder meetings.  However, in the event of any taking by the
Company of a record of the holders of any class of securities for the purpose of
determining  the holders thereof who are entitled to receive any dividend (other
than a cash  dividend)  or  other  distribution,  any  right to  subscribe  for,
purchase  or  otherwise  acquire  any  shares of stock of any class or any other
securities or property, or to receive any other right, the Company shall mail to
each Warrant  Holder,  at least 10 days prior to the date specified  therein,  a
notice  specifying  the date on which  any such  record  is to be taken  for the
purpose of such dividend, distribution or right, and the amount and character of
such dividend, distribution or right.

         9.  Replacement  of  Warrant.   Upon  receipt  of  evidence  reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of the
Warrant and, in the case of any such loss,  theft or destruction of the Warrant,
upon delivery of an indemnity  agreement or security reasonably satis factory in
form and  amount  to the  Company  or,  in the case of any such  mutilation,  on
surrender  and  cancellation  of such  Warrant,  the Company at its expense will
execute and deliver, in lieu thereof, a new Warrant of like tenor.

         10. Consent to Jurisdiction. Each of the Company and the Warrant Holder
(i) hereby irrevocably submits to personal  jurisdiction in any state or federal
court located in the State of California for the purposes of any suit, action or
proceeding arising out of or relating to this Warrant.

         11.  Entire  Agreement;  Amendments.  This  Warrant  and the  Agreement
contain  the entire  understanding  of the parties  with  respect to the matters
covered  herein and  therein.  No  provision  of this  Warrant  may be waived or
amended  other than by a written  instrument  signed by the party  against  whom
enforcement of any such amendment or waiver is sought.

         12. Restricted Securities.

         RE:      Sigma Designs, Inc. Registration Statement on Form S-3

Ladies and Gentlemen:

         We have examined  Post-Effective  Amendment  No. 1 to the  Registration
Statement  on Form  S-3 to be filed by you  with  the  Securities  and  Exchange
Commission on December 10, 1998 (the  "Registration  Statement"),  in connection
with the registration under the Securities Act of 1933, as amended, of 1,100,000
shares of your  Common  Stock,  no par value  (the  "Shares"),  all of which are
authorized  and will be issued to the  selling  shareholders  identified  in the
Registration  Statement  (the  "Selling  Shareholders").  The  Shares  are to be
offered by the Selling  Shareholders  for sale to the public as described in the
Registration Statement. As your counsel in connection with this transaction,  we
have examined the proceedings  taken and proposed to be taken in connection with
the sale of the Shares.

         It is our opinion that, upon completion of the proceedings  being taken
or contemplated to be taken prior to the  registration of the Shares,  including
such proceedings to be carried out in accordance with the securities laws of the
various states, where required,  the Shares, when sold in the manner referred to
in the Registration  Statement,  will be legally and validly issued,  fully paid
and nonassessable.

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

                                            Very truly yours,

                                            WILSON SONSINI GOODRICH & ROSATI
