                              --------------------
     This  Prospectus  relates to 82,777 shares (the  "Shares") of Common Stock,
par value  $.001 per share  (the  "Common  Stock"),  of  Wonderware  Corporation
("Wonderware"  or  the  "Company").   The  Shares  may  be  offered  by  certain
stockholders  of the Company (the "Selling  Stockholders")  from time to time in
transactions on the Nasdaq National Market, in privately negotiated transactions
or a  combination  of such methods of sale, at fixed prices that may be changed,
at market  prices  prevailing  at the time of sale,  at prices  related  to such
prevailing market prices or at negotiated prices.  The Selling  Stockholders may
effect such transactions by selling the Shares to or through broker-dealers, and
such  broker-dealers  may  receive   compensation  in  the  form  of  discounts,
concessions or commissions  from the Selling  Stockholders  or the purchasers of
the Shares for whom such broker-dealers may act as agent or to whom they sell as
principal or both (which compensation to a particular  broker-dealer might be in
excess  of  customary  commissions).  See  "Selling  Stockholders"  and "Plan of
Distribution."

     None  of  the  proceeds  from  the  sale  of  the  Shares  by  the  Selling
Stockholders  will be  received by the  Company.  The Company has agreed to bear
certain  expenses in  connection  with the  registration  and sale of the Shares
being offered by the Selling  Stockholders.  The Company has agreed to indemnify
the  Selling  Stockholders   against  certain  liabilities,   including  certain
liabilities  under  the  Securities  Act of  1933,  as  amended.  See  "Plan  of
Distribution."

     The Common  Stock of the  Company is traded on the Nasdaq  National  Market
under the  Symbol  "WNDR." On  November  21,  1996,  the last sale price for the
Common Stock as reported by the Nasdaq National Market was $8.00 per share.

<PAGE>
                            THE COMPANY

     Wonderware  supplies  Microsoft  Windows-based  software  products  for the
industrial  automation  market. The Company was formed as a partnership in April
1987 and was  incorporated  in California  in June 1988 as  Wonderware  Software
Development  Corporation.  The Company  reincorporated in Delaware in July 1993.
Unless the context otherwise  requires,  "Wonderware" and the "Company" refer to
Wonderware Corporation,  a Delaware corporation,  and the Delaware corporation's
predecessor.  The  Company's  executive  offices are  located at 100  Technology
Drive, Irvine, California 92618, and its telephone number is (714) 727-3200.

     This Prospectus  includes tradenames and trademarks of companies other than
Wonderware.
                                  RISK FACTORS

     In  addition to the other  information  set forth in this  Prospectus,  the
following risk factors should be considered  carefully in evaluating the Company
and its business before purchasing any shares of Common Stock offered hereby.

Fluctuations in Quarterly Operating Results

     The Company has recently experienced significant  fluctuations in quarterly
operating results and expects to continue to experience significant fluctuations
in future quarterly  operating results.  Such fluctuations have been caused, and
in the future may be caused,  by a number of factors,  including,  among others:
competition  and pricing in the software  industry;  delays in  introduction  of
products  or product  enhancements  by the  Company,  its  competitors  or other
providers of hardware,  software and components  for the  industrial  automation
market;  customer  order  deferrals  in  anticipation  of new  products;  market
acceptance  of new  products;  reduction  in demand for  existing  products  and
shortening  of product  life  cycles as a result of new  product  introductions;
changes  in  operating  expenses;  the size and  timing  of  individual  orders;
software  "bugs" or other product  quality  problems;  seasonality  of revenues;
changes in Company strategy; personnel changes; foreign currency exchange rates;
mix of products sold; and general economic conditions.  As a result, the Company
believes that period-to-period comparisons of its results of operations are not
necessarily  meaningful  and should not be relied upon as  indications of future
performance.

     Because the Company  ships  software  products  within a short period after
receipt of an order,  the Company  typically does not have a material backlog of
unfilled  orders,  and  revenues in any quarter are  substantially  dependent on
orders booked in that quarter. The Company's expense levels are based in part on
its  expectations  as to future revenues and the Company may be unable to adjust
spending in a timely manner to compensate for any revenue shortfall.

                                       2.
<PAGE>

Accordingly,  operating  results  would be adversely  affected by a reduction in
revenues in that quarter since the majority of the Company's expenses are fixed.
Any  significant  weakening  in demand  would have an almost  immediate  adverse
impact on the  Company's  operating  results  and on the  Company's  ability  to
maintain  profitability.  In addition,  fluctuations  in operating  results have
resulted  in, and may in the future  result in,  volatility  in the price of the
Company's Common Stock.

Product Concentration

     The  Company's  current  products are limited in number,  and the Company's
product  revenues are derived  primarily  from the family of Wonderware  InTouch
products for industrial  automation  applications.  Revenues from the Wonderware
InTouch family of products  represent over 80% of the Company's  total revenues.
The Company  expects that revenues from these  products will continue to account
for a substantial portion of the Company's revenues in future periods,  but that
the share of revenues  derived from other products will increase as new products
are  introduced.  The life cycles of the  Company's  products  are  difficult to
estimate due in large measure to the recent  emergence of the Company's  market,
the future effect of product  enhancements and future  competition.  Declines in
demand for these  products,  whether as a result of  competition,  technological
change or otherwise, or price reductions would have a material adverse effect on
the Company's operating results.

Competition

     The market for the  Company's  products is  increasingly  competitive.  The
Company  expects  competition  to continue to increase,  which could result in a
decline in the Company's  market share as other companies  introduce  additional
and more competitive  Microsoft  Windows-based  products in this emerging market
segment.  Many  of  the  Company's  present  or  anticipated   competitors  have
substantially greater financial, technical, marketing and sales resources than
the Company.  There can be no assurance that the Company will be able to compete
successfully in the future.

Dependence on Microsoft Windows

     The Company's software development tools are designed for use with personal
computers  running in the Microsoft Windows  operating  environment,  and future
sales of the Company's  products are dependent upon continued use of Windows and
Windows NT. In addition,  changes to Windows (such as the release of Windows 95)
or Windows NT require  the Company to  continually  upgrade  its  products.  Any
inability to produce  upgrades or any material delay in doing so would adversely
affect the Company's  operating  results.  The  successful  introduction  of new
operating  systems or  improvements of existing  operating  systems that compete
with Windows or Windows NT also could  adversely  affect sales of the  Company's
products and have a material adverse effect on the
Company's operating results.

                                       3.
<PAGE>


Rapid Technological Change

     The  market  for  the  Company's   products  is   characterized   by  rapid
technological  advances,  evolving  industry  standards,   changes  in  end-user
requirements and frequent new product introductions and enhancements.  While the
Company to date has been  committed  to the  Microsoft  Windows  and  Windows NT
platforms,  the  introduction  of products  embodying new  technologies  and the
emergence of new industry standards could render the Company's existing products
and  products  currently  under  development  obsolete  and  unmarketable.   The
Company's  future  success  will  depend upon its ability to enhance its current
products  and to  develop  and  introduce  new  products  that  keep  pace  with
technological  developments,  respond  to  evolving  end-user  requirements  and
achieve market  acceptance.  Any failure by the Company to anticipate or respond
adequately  to  technological  developments  or  end-user  requirements,  or any
significant  delays in product  development or  introduction,  could result in a
loss of  competitiveness  or revenues.  In the past, the Company has experienced
delays in the introduction of new products and product  enhancements.  There can
be no assurance  that the Company will be successful in developing and marketing
new products or product  enhancements on a timely basis or that the Company will
not  experience  significant  delays in the future,  which could have a material
adverse effect on the Company's results of operations. In addition, there can be
no assurance that new products or product enhancements  developed by the Company
will achieve market acceptance.

Integration of Acquisitions

     In  July  1995,  the  Company   entered  into  an  Agreement  and  Plan  of
Reorganization with EnaTec Software Systems,  Inc., a developer of Windows-based
manufacturing  execution systems software ("EnaTec"),  pursuant to which a newly
formed,  wholly owned subsidiary of the Company was merged with and into EnaTec.
In August 1995, the Company entered into an Agreement and Plan of Reorganization
with Soft Systems Engineering,  Inc., a developer of batch manufacturing process
software  ("SSE"),  pursuant to which SSE was merged with another  newly formed,
wholly owned  subsidiary of the Company.  The integration of EnaTec and SSE into
the Company,  the  completion of the  development  of their  respective  product
offerings  and the  integration  of such product  offerings  into the  Company's
product offerings has diverted a significant portion of the Company's management
and  financial  resources and is expected to continue to do so for an indefinite
period of time.  There can be no assurance  that further  difficulties  will not
arise  in  integrating  the  operations  of  EnaTec  and  SSE,   completing  the
development of their  products or integrating  those products with the Company's
products.  The failure to accomplish  any of the goals of either  acquisition or
the failure to  successfully  integrate  the  operations of either EnaTec or SSE
would have a material  adverse  effect on the  Company's  operating  results and
financial  condition.  There can be no  assurance  that the Company will realize
increased  revenues or profits as a result of the acquisition of EnaTec and SSE.
In  particular,  the new  product  offerings  resulting  from such  acquisitions
address  new  markets  with  which  the  Company's  existing   distributors  are
relatively unfamiliar, and there can be no assurance that such distributors will
be able to successfully market and sell these new products.

                                       4.
<PAGE>

     In September  1996, the Company signed a letter of intent to acquire all of
the outstanding shares of capital stock of its software  distributor in Germany,
ICT-Wonderware GmbH  ("ICT-Wonderware").  It is the intention of the Company and
ICT-Wonderware  to consummate  the  acquisition no later than December 31, 1996.
There  can be no  assurance  that the  integration  of  ICT-Wonderware  into the
Company will not divert a significant  portion of the Company's  management  and
financial  resources  or that  difficulties  will not arise in  integrating  the
operations  of  ICT-Wonderware  into  the  Company.  Moreover,  there  can be no
assurance  that the  acquisition  of  ICT-Wonderware  will  result in  increased
revenues or profits.  The failure to accomplish the goals of the  acquisition of
ICT-Wonderware  could have a material adverse effect on the Company's  operating
results and financial condition.

Legal Proceedings
   
     On July 9, 1996,  the Company  filed a complaint in the  Superior  Court of
California for the County of Orange against Constantin S. Delivanis and Vladimir
Preysman,   formerly  the  Vice   President   and  Vice   President-Engineering,
respectively,  of the Company's  Cupertino  Development  Center.  This complaint
alleges fraud, negligent misrepresentation,  duress, securities fraud, breach of
the implied  covenant of good faith and fair  dealing,  and breach of  fiduciary
duty against Messrs.  Delivanis and Preysman.  The Cupertino  Development Center
was  established  upon the  Company's  acquisition  of EnaTec,  in which Messrs.
Delivanis and Preysman  owned a substantial  majority of the stock (see Note 12,
Acquisitions,  of Notes to  Consolidated  Financial  Statements  included in the
Company's  1995  Annual  Report  to  Stockholders   for  a  description  of  the
acquisition of EnaTec). The Company is seeking compensatory and punitive damages
with  respect to its claims,  as well as the costs  incurred  in pursuing  these
claims.  Mr.  Delivanis  and Mr.  Preysman's  employment  with the  Company  was
terminated.  Both Mr.  Delivanis  and Mr.  Preysman  answered the  complaint and
asserted  cross-claims  against  the  Company,   alleging  breach  of  contract,
termination  in  violation  of  public  policy,  defamation  (slander  per  se),
intentional infliction of emotional distress,  negligent infliction of emotional
distress,  negligence,  common law fraud and deceit, and civil conspiracy.  Both
requested relief in the form of compensatory and punitive damages as well as the
costs incurred in pursuing  their  cross-claims.  In addition,  on September 27,
1996,  Mr.  Delivanis,  Mr.  Preysman,  and the  Delivanis  Family Trust filed a
complaint   for   declaratory   judgment  and  specific   performance,   seeking
registration  of certain  Wonderware  stock.  The company  has  demurred to that
complaint. It is too early to determine the impact, if any, of these proceedings
on the Company or the results of the Company's operations.

                                       5.
<PAGE>
     On October  16,  1996,  the  Company  filed an action in the United  States
District  Court  for the  Central  District  of  California  against  Cyberlogic
Technologies,  Inc. ("Cyberlogic") and Intellution,  Inc.  ("Intellution").  The
complaint  alleges that Cyberlogic and Intellution  have infringed the copyright
in a particular  software  program which Cyberlogic  originally  developed under
contract  for  the  Company.  The  complaint  seeks  preliminary  and  permanent
injunctive  relief as well as actual and punitive  damages and attorneys'  fees.
There can be no  assurance  that  Cyberlogic  and  Intellution  will not  assert
counterclaims  against the Company and no assurance can be given  concerning the
ultimate outcome of this matter. In any event, even if the Company is successful
in such proceedings,  the legal and other costs associated with such proceedings
could be substantial.

Foxboro Litigation

     In 1995, The Foxboro Company ("Foxboro")  initiated  litigation against SSE
asserting  claims  with  respect  to  Foxboro's  ownership  interest  in certain
software  developed by SSE, which  interest is subject to a repurchase  right in
favor of SSE. There can be no assurance that the results of such litigation will
not  have a  material  adverse  effect  on the  Company.  There  also  can be no
assurance that SSE will be able to repurchase  Foxboro's  ownership interest or,
if such repurchase is  accomplished,  that it would be on terms favorable to the
Company.  Although it is too early to determine the ultimate outcome,  there can
be no  assurance  that,  if  such  repurchase  is  not  accomplished,  Foxboro's
ownership  interest or the exercise of Foxboro's  rights under  agreements  with
SSE,  would not have a material  adverse effect on the Company or the results of
the Company's operations.
     For further information concerning the Foxboro litigation proceedings,  see
the Company's  Annual  Report on Form 10-K for the year ended  December 31, 1995
and the Company's subsequent reports on Form 10-Q.

Management of Growth

     The  Company  has  recently  experienced  rapid  growth  in the  number  of
employees,  the scope of its operating and financial  systems and the geographic
area of its operations.  This growth has resulted in an increase in the level of
responsibility  for both existing and new  management  personnel.  To manage its
growth  effectively,  the Company will be required to continue to implement  and
improve its operating and financial systems and to expand,  train and manage its
employee base. There can be no assurance that the management  skills and systems
currently  in place will be  adequate  if the  Company  continues  to grow.  The
Company may make additional acquisitions in the future. The Company's management
has only limited  experience with  acquisitions,  which involve  numerous risks,
including difficulties in the assimilation of the operations and products of the
acquired companies,  the diversion of management's attention from other business
concerns and the potential loss of key employees of the acquired companies.

                                       6.

<PAGE>

Key Employees

     The  Company's  continued  success will depend upon its ability to retain a
number of key employees,  including Roy H. Slavin, the Company's Chairman of the
Board,  President and Chief Executive  Officer,  most of whom are not subject to
employment  agreements or agreements that restrict their ability to compete with
the Company  following the  termination of their  employment.  In addition,  the
Company  believes  that its  future  success  will  depend in large  part on its
ability to attract and retain highly skilled technical, managerial and marketing
personnel.  Competition  for such  personnel  is  intense,  and  there can be no
assurance  that the Company will be successful in attracting  and retaining such
personnel.  The loss of certain key  employees  or the  Company's  inability  to
attract  and retain  other  qualified  employees  could have a material  adverse
effect on the Company's business.

Reliance upon Distribution Channel

     The  Company  has  relied and  expects to  continue  to rely  primarily  on
independent  distributors  for the marketing and  distribution  of its products.
These distributors may also represent other lines of products, some of which may
be complementary to or competitive  with the Company's  products.  The Company's
distributors  are not within the control of the Company and are not obligated to
purchase   products  from  the  Company.   While  the  Company   encourages  its
distributors  to focus  primarily  on the  promotion  and sale of the  Company's
products, there can be no assurance that these distributors will not give higher
priority to the sale of other products, including products developed by existing
or potential  competitors.  A reduction in sales  efforts or  discontinuance  of
sales of the Company's  products by its distributors could lead to reduced sales
and could adversely affect the Company's  operating  results.  In addition,  the
Company has recently expanded its product offering to include software products,
such as its Wonderware InTrack product,  that address new markets with which the
Company's  existing  distributors  are  relatively  unfamiliar.  There can be no
assurance as to the continued  viability or financial stability of the Company's
distributors, the ability of the Company's existing distributors to successfully
market and sell the Company's new product  offerings,  the Company's  ability to
retain  its  existing   distributors  or  the  Company's   ability  to  add  new
distributors  in  the  future.   In  addition,   as  a  result  of  new  product
introductions  or pricing  actions  by the  Company  or  others,  the  Company's
distributors  or  end-users  may alter  the  expected  timing  of their  product
purchases,  thereby  exacerbating  the  possible  variability  of the  Company's
quarterly operating results.

                                       7.

Dependence on General Economic Conditions

     Based in part on the growth in the  overall  market  for and the  Company's
penetration  of the  industrial  automation  software  market,  as  well  as the
geographic  and  industry  diversity  of the  Company's  customers,  the Company
believes that general economic conditions have not had a material adverse effect
on the  Company's  results  of  operation  to date.  There can be no  assurance,
however, that economic conditions will not have a material adverse effect on the
Company in the future.

International Sales

     The Company  derived  approximately  $17.9  million (39%) and $16.3 million
(42%) of its total  revenues  from  international  sales  during  the first nine
months of 1995 and 1996,  respectively.  The Company expects that  international
sales will continue to represent a significant percentage of its total revenues.
The Company's  international  operations are subject to various risks, including
exposure  to  currency  fluctuations,  regulatory  requirements,  political  and
economic  instability and trade  restrictions.  Although the Company's sales are
typically made in U.S. dollars,  a weakening in the value of foreign  currencies
relative to the U.S.  dollar could have an adverse impact on the effective price
of the  Company's  products  in its  international  markets.  Delays in  foreign
language  translations  and other measures to "localize"  the Company's  product
offerings for  international  markets could also adversely impact the timing and
amount of  international  sales.  In  addition,  the  Company's  business may be
adversely affected by lower sales levels in Europe, which typically occur during
the summer months.

Dependence on Proprietary Rights

     The Company  regards its software as proprietary and attempts to protect it
with copyrights,  trademarks,  trade secret laws and restrictions on disclosure,
copying and  transferring  title.  However,  the  Company  has no  patents,  and
existing  copyright  laws  afford  only  limited  practical  protection  for the
Company's  software.  In  addition,  the laws of some  foreign  countries do not
protect the  Company's  proprietary  rights to the same extent as do the laws of
the United States.  The Company  licenses its products  primarily  under "shrink
wrap" license  agreements  that are not signed by licensees and therefore may be
unenforceable under the laws of certain foreign  jurisdictions.  In addition, in
some  instances the Company  licenses its products  under  agreements  that give
licensees  limited  access  to  the  source  code  of  the  Company's  products.
Accordingly,  despite  precautions taken by the Company,  it may be possible for
unauthorized third parties to copy certain portions of the Company's products or
to obtain and use information  that the Company  regards as proprietary.  As the
number of software  products in the industry  increases and the functionality of
these products  further  overlaps,  the Company believes that such software will
become  increasingly  the subject of claims  that such  software  infringes  the
rights of others.
                                       
                                       8.
<PAGE>

     Although the Company  does not believe  that its  products  infringe on the
rights  of  third  parties,  from  time  to time  third  parties  have  asserted
infringement claims against the Company and there can be no assurance that third
parties will not assert  infringement  claims against the Company in the future.
Moreover,  there can be no assurance that any such assertions will not result in
costly  litigation  or require the  Company to obtain a license to  intellectual
property  rights of such parties.  In addition,  there can be no assurance  that
such licenses will be available on  reasonable  terms,  or at all. In July 1995,
the Company and Touch  Technologies,  Inc.  entered into a Settlement  Agreement
pursuant  to which  the  Company  may  continue  to use the  marks  InTouch  and
Wonderware  InTouch in connection  with its business and products until December
31, 1998.

Potential Volatility of Stock Price

     The Company believes  factors such as quarterly  fluctuations in results of
operations,  management  changes,  delays in the introduction of new products or
product enhancements, and announcements of new products by the Company or by its
competitors  has caused and may continue to cause the market price of the Common
Stock to fluctuate substantially.  In addition, in recent years the stock market
in  general,  and  the  shares  of  technology  companies  in  particular,  have
experienced  extreme  price  fluctuations.   These  broad  market  and  industry
fluctuations  may  adversely  affect the market  price of the  Company's  Common
Stock.

Anti-Takeover  Effects of Certain Charter  Provisions,  Unissued  Preferred
Stock and Delaware Law

     The Company's  Board of Directors has the authority,  without action by the
Stockholders,  to fix the  rights  and  preferences  of and to issue  shares  of
Preferred  Stock.  In February 1996, the Board of Directors  adopted a Preferred
Share Purchase Rights Plan (commonly  known as a "poison pill"),  which may have
the effect of delaying or  preventing  a change in control of the  Company.  The
Company is also subject to the  anti-takeover  provisions  of Section 203 of the
Delaware  General  Corporation  Law.  Furthermore,  certain  provisions  of  the
Company's  Certificate of Incorporation and Bylaws may discourage  certain types
of  transactions  involving  an actual or  potential  change in  control  of the
Company,  including  transactions  in which  the  stockholders  might  otherwise
receive a premium for their shares over then current  prices,  and may limit the
ability  of the  stockholders  to approve  transactions  that they deem to be in
their best interest.

                              PLAN OF DISTRIBUTION

     The Company has been advised that the Selling  Stockholders may sell Shares
from  time  to  time  in  transactions  on  the  Nasdaq  National   Market,   in
privately-negotiated  transactions  or a combination of such methods of sale, at
fixed prices which may be changed,  at market  prices  prevailing at the time of
sale,  at prices  related  to such  prevailing  market  prices or at  negotiated
prices.  The Selling  Stockholders  may effect such  transactions by selling the
Shares  to or  through  broker-dealers,  and  such  broker-dealers  may  receive
compensation  in the form of  discounts,  concessions  or  commissions  from the
Selling   Stockholders   or  the   purchasers   of  the  Shares  for  whom  such
broker-dealers  may act as  agent or to whom  they  sell as  principal,  or both
(which  compensation  to a  particular  broker-dealer  might  be  in  excess  of
customary commission).

     The Selling  Stockholders and any broker-dealers who act in connection with
the sale of Shares hereunder may be deemed to be  "underwriters" as that term is
defined in the Securities Act of 1933, as amended (the  "Securities  Act"),  and
any  commissions  received  by them and  profit on any  resale of the  Shares as
principal might be deemed to be underwriting discounts and commissions under the
Securities Act.

     The  validity of the issuance of the Common  Stock  offered  hereby will be

Item 15.  Indemnification of Officers and Directors.

     Under Section 145 of the Delaware  General  Corporation Law, the Registrant
has broad powers to indemnify  its directors  and officers  against  liabilities
they may incur in such capacities,  including  liabilities  under the Securities
Act of  1933,  as  amended.  The  Registrant's  Bylaws  also  provide  that  the
Registrant will indemnify its directors and executive officers and may indemnify
its other  officers,  employees  and  other  agents to the  fullest  extent  not
prohibited by Delaware law.

     The Registrant's Amended and Restated Certificate of Incorporation provides
that the liability of its directors for monetary  damages shall be eliminated to
the fullest extent  permissible  under  Delaware law.  Pursuant to Delaware law,
this includes  elimination  of liability for monetary  damages for breach of the
directors' fiduciary duty of care to the Registrant and its stockholders.  These
provisions  do not  eliminate the  directors'  duty of care and, in  appropriate
circumstances,   equitable  remedies  such  as  injunctive  or  other  forms  of
non-monetary relief will remain available under Delaware law. In addition,  each
director will  continue to be subject to liability for breach of the  director's
duty of loyalty to the  Registrant,  for acts or omissions  not in good faith or
involving  intentional  misconduct,  for  knowing  violations  of  law,  for any
transaction from which the director derived an improper  personal  benefit,  and
for payment of dividends or approval of stock  repurchases or  redemptions  that
are unlawful under Delaware law. The provision also does not affect a director's
responsibilities  under any other laws,  such as the federal  securities laws or
state or federal environmental laws.

     The Registrant has entered into agreements with its directors and executive
officers that require the Registrant to indemnify such persons against expenses,
judgments, fines, settlements and other amounts actually and reasonably incurred
<PAGE>
(including  expenses of a derivative  action) in connection with any proceeding,
whether  actual or  threatened,  to which any such person may be made a party by
reason of the fact  that such  person is or was a  director  or  officer  of the
Registrant or any of its affiliated  enterprises,  provided such person acted in
good  faith and in a manner  such  person  reasonably  believed  to be in or not
opposed  to the best  interests  of the  Registrant  and,  with  respect  to any
criminal  proceeding,  had no reasonable cause to believe his or her conduct was
unlawful. The indemnification  agreements also set forth certain procedures that
will apply in the event of a claim for indemnification thereunder.

     At  present,  there is no pending  litigation  or  proceeding  involving  a
director  or  officer of the  Registrant  as to which  indemnification  is being
sought nor is the Registrant aware of any threatened  litigation that may result
in claims for indemnification by any officer or director.

Item 17.  Undertakings.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors,  officers, and controlling persons of the
Registrant  pursuant to the  provisions  described in Item 15 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
Act and is, therefore, unenforceable. In the

                                      II-2
<PAGE>
event that a claim for indemnification  against such liabilities (other than the
payment by the Registrant of expenses  incurred or paid by a director,  officer,
or controlling person of the Registrant in the successful defense of any action,
suit, or  proceeding)  is asserted by such  director,  officer,  or  controlling
person in connection with the securities being registered,  the Registrant will,
unless in the opinion of its counsel the matter has been settled by  controlling
precedent,  submit to a court of appropriate  jurisdiction  the question whether
such  indemnification by it is against public policy as expressed in the 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, a post-effective amendment to this registration statement:

                           (i) to include any  prospectus required by section
                  10(a)(3) of the Securities Act of 1933;

                           (ii) to reflect in the prospectus any facts or events
                  arising after the effective date of the registration statement
                  (or the most recent  post-effective  amendment thereof) which,
                  individually  or in the  aggregate,  represent  a  fundamental
                  change  in the  information  set  forth  in  the  registration
                  statement;

                           (iii)  to  include  any  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;

         provided,  however,  that  clauses  (i) and  (ii) do not  apply  if the
         information  required to be included in a  post-effective  amendment by
         these clauses is contained in periodic  reports filed by the Registrant
         pursuant to section 13 or section 15(d) of the Securities  Exchange Act
         of  1934  that  are  incorporated  by  reference  in  the  registration
         statement;

                  (2) that, for the purpose of determining  any liability  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; and

                  (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.

                                      II-3

<PAGE>
     The  undersigned   Registrant  hereby  undertakes  that,  for  purposes  of
determining  any liability  under the Securities Act of 1933, each filing of the
Registrant's  annual  report  pursuant to section  13(a) or section 15(d) of the
Securities  Exchange  Act of 1934  (and,  where  applicable,  each  filing of an
employee  benefit  plan's  annual  report  pursuant  to  Section  15(d)  of  the
Securities  Exchange  Act of 1934)  that is  incorporated  by  reference  in the
registration  statement  shall  be  deemed  to be a new  registration  statement
relating to the securities offered therein,  and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

The undersigned Registrant undertakes that:

                  (1) for  purposes  of  determining  any  liability  under  the
         Securities  Act of  1933,  the  information  omitted  from  the form of
         prospectus filed as part of the registration statement in reliance upon
         Rule  430A  and  contained  in the  form  of  prospectus  filed  by the
         Registrant  pursuant  to Rule  424(b)(1)  or (4) or  497(h)  under  the
         Securities Act shall be deemed to be part of the registration statement
         as of the time it was declared effective; and

                  (2) for the purpose of  determining  any  liability  under the
         Securities Act of 1933, each  post-effective  amendment that contains a
         form of prospectus shall be deemed to be a new  registration  statement
         relating to the securities  offered  therein,  and the offering of such
         securities  at that time  shall be deemed to be the  initial  bona fide
         offering thereof.

Statement  to be  signed  on its  behalf  by  the  undersigned,  thereunto  duly

Ladies and Gentlemen:

You have  requested  our opinion with respect to certain  matters in  connection
with the filing by Wonderware  Corporation  (the  "Company")  of a  Registration
Statement on Form S-3 (the  "Registration  Statement")  with the  Securities and
Exchange  Commission  covering the offer and sale of up to  eighty-two  thousand
seven hundred  seventy-seven  (82,777) shares of the Company's Common Stock, par
value $.001, by certain stockholders, as described in the Registration Statement
(the "Shares").

In connection with this opinion, we have examined the Registration Statement and
related Prospectus, your Certificate of Incorporation,  as amended, your Bylaws,
as amended and such other documents, records, certificates,  memoranda and other
instruments  as we deem  necessary as a basis for this opinion.  We have assumed
the genuineness and authenticity of all documents  submitted to us as originals,
the conformity to originals of all documents  submitted to us as copies thereof,
and the due  execution  and delivery of all  documents  where due  execution and

On the basis of the foregoing,  and in reliance  thereon,  we are of the opinion
that the Shares are validly issued, fully paid, and nonassessable.
