                       RISK FACTORS

     Investors should consider carefully the following
factors, in addition to the other information contained in
this Prospectus, before purchasing the shares of Common
Stock offered hereby.

     Fluctuations in Operating Results.  The Company's
operating expenses are partially based on its expectations
of future revenue.  The Company's results of operations may
be adversely affected if revenue does not materialize in a
quarter as expected.  Since expense levels are usually
committed in advance of revenues and because only a small
portion of expenses vary with revenue, the Company's
operating results may be impacted significantly by lower
revenue.  Based on the Company's operating history and
factors that may cause fluctuations in the quarterly
results, quarter to quarter comparisons should not be relied
upon as indicators of future performance.  Although the
Company's revenues are not generally seasonal in nature, the
Company from time to time has experienced decreases in first
quarter revenue versus the preceding fourth quarter which is
believed to result primarily from the capital purchase
cycles of the Company's customers.  Due in part to
restructuring charges incurred by the Company, the Company
experienced net losses in 1990, 1991 and 1993 of $9,348,000,
$22,403,000 and $12,779,000, respectively.

     Growth through Acquisitions.  Since May 1988, the
Company has participated in seven major mergers and
acquisitions.  These transactions have been motivated by a
number of factors, including the desire to obtain new
technologies, the desire to expand and enhance the Company's
product lines and the desire to attract key personnel.
Growth through acquisition has several identifiable risks,
including risks related to integration of the previously
distinct businesses into a single unit, the substantial
management time devoted to such activities, undisclosed
liabilities, the failure of anticipated benefits, such as
cost savings and synergies, to materialize and product
transition issues.  The Company believes that such risks
contributed to the Company's losses during 1990, 1991 and
1993.

     Key Personnel.  The Company is dependent upon the
efforts and abilities of its senior management, its research
and development staff and a number of other key management,
sales, support and technical personnel.  The success of the
Company will depend to a large extent upon its ability to
retain and continue to attract qualified technical and other
employees.  Competition for qualified personnel in the
software industry is intense, and the loss of key employees
could have a material adverse effect on the Company's
business, operating results and financial condition,
particularly if key personnel are subsequently employed by a
competitor.  The Company carries key man life insurance in
the amount of $5 million with respect to its President and
Chief Executive Officer, Joseph B. Costello.

     Technological Change and Development of New Products
and Services.  Because of rapid technological changes in the
electronic design automation ("EDA") industry, the Company's
future revenues will depend on its ability to develop or
acquire new products and enhance its existing products on a
timely basis to accommodate the latest technological
advances in computer software and hardware.  The Company's
products are designed for a narrow technology and are
dedicated to the design and manufacturing processes,
procedures, techniques and methods currently in use by
integrated circuit manufacturers.  The EDA software tools
currently licensed by the Company are usable primarily in
connection with current manufacturing processes.  Changes in
manufacturing technology or processes could render one or
more of the Company's software tools obsolete.  The
Company's EDA software tools currently have an estimated
life cycle of between two and seven years.  There can be no
assurance that the Company will be able to avoid
obsolescence of its products or that any new or enhanced
products it develops or markets will be competitive or
achieve market acceptance.  Moreover, any significant delays
in product development could result in a loss of
competitiveness of the Company's products and loss of
revenues.

     The Company has recently increased its focus on
offering professional services to its customers.  To the
extent that the Company is not able to recruit, train and
retain a skilled consulting force that is able to provide
services that satisfy customers' expectations, the Company's
business and operating results could be adversely affected.

     Competition.  The Company faces intense competition in
the EDA product market, which continues to be characterized
by aggressive pricing practices and new market entrants.
The Company competes with other companies that sell
competing products and with internal EDA software
development groups of potential customers.  Some of the
Company's competitors may have substantially greater
financial, marketing and technological resources than the
Company.  There can be no assurance that the Company will be
able to compete successfully.

     Because the EDA industry is labor intensive rather than
capital intensive, the number of potential competitors to
the Company is significant.  A potential competitor who
possesses the necessary knowledge of electronic circuit and
systems design, production and operation could develop EDA
tools using a moderately priced computer workstation and
bring such tools to market quickly.  If such an EDA software
tool were to surpass the technology of a tool of the
Company, the attention of customers might rapidly shift to
the new tool, resulting in a precipitous decline in the
sales of the Company's comparable product.

     The Company has in the past discounted EDA product
prices where deemed necessary for competitive reasons or in
connection with volume purchase agreements with major
customers.  In the past, discounts of up to 60% of the list
prices of the EDA products have been given.  Although the
Company is striving to reduce discounts, it anticipates that
it may be required to discount EDA product prices under
similar circumstances in the future.

     Intellectual Property Rights.  The Company relies
principally upon trade secrets and copyright laws to protect
its intellectual property rights.  In general, the Company
seeks to preserve its trade secrets by licensing (rather
than selling) its products, by using nondisclosure
agreements, by limiting access to confidential information
and through other security measures.  Despite these
precautions, it may be possible for third parties to copy
aspects of the Company's products or to obtain and use
information that the Company regards as proprietary.  The
Company has relatively few patents, and existing copyright
laws afford only limited protection.  There has been an
increase in the number of patents issued in the United
States relating to EDA software and, accordingly, the risk
of patent infringement in the industry can be expected to
increase.  In addition, the proprietary rights and laws of
certain countries do not protect the Company's products and
intellectual property rights to the same extent as do the
laws of the United States.
   
     International Revenues.  A large percentage of the
total revenues of the Company has been derived from
international sources, principally in Japan and Europe.
International sales have constituted approximately one-half
of the Company's total revenues for the years ended December
31, 1991, 1992, 1993 and 1994, and it is anticipated that
international revenues will continue to constitute a
significant portion of total revenues for the Company.
International revenues are subject to certain increased
risks normally associated with international operations,
including, among others, adoption and expansion of
government trade restrictions, currency conversion risks,
limitations on repatriation of earnings and reduced
protection of intellectual property rights.  In 1993 and to
a lesser extent in 1994, the Company generated reduced
levels of sales from Japan.  Although the Company has taken
certain steps to address the impact on its revenues of the
weak Japanese economy, such as reorganizing its direct sales
force in Japan, changing certain of its distribution
relationships and introducing new systems products to
address customer design needs, there can be no assurance
that these steps will strengthen the Company's revenue
volume in Japan.  Due to the January 1995 earthquake and
continuing weak business conditions in Japan, the Company
could continue to experience a reduced level of activity
from this important market.  A continued low level or
further reduction of orders from Japan could have a material
adverse impact on the Company's operating results.  Many of
the products offered by the Company are subject to
restrictions on export under the regulations of the United
States Department of Commerce and Department of State, and
changes in United States export policy, as well as changes
in the import restrictions of foreign countries, could have
an adverse effect on the Company's business.
    
     Volatility of Stock Prices.  The market price of the
Company's Common Stock has been and may continue to be
volatile.  This volatility may result from a number of
factors, including fluctuations in the Company's quarterly
revenues and net income, announcements of technical
innovations or new commercial products by the Company or its
competitors, and market conditions in the EDA,
semiconductor, telecommunications, computer hardware and
computer software industries.  In addition, the stock market
has experienced and continues to experience extreme price
and volume fluctuations which have affected the market
prices of securities, particularly those of technology
companies, and which have often been unrelated to the
operating performance of the companies.  These broad market
fluctuations, as well as general economic and political
conditions, may adversely affect the market price of the
Company's Common Stock.

    
                     RECENT DEVELOPMENTS

     The Company announced on January 24, 1995 its financial results
for the year ended December 31, 1994.  The Company intends to file
its Annual Report on Form 10-K for the year ended December 31, 1994
on or about March 31, 1995, which report will supersede the following
general discussion of the Company's financial results for such period.

     Revenue increased 16% for the year ended December 31, 1994 to
$429.1 million compared to $368.6 million for the year ended
December 31, 1993.  Product revenue increased approximately $28.9
million in 1994 as compared to 1993 due to increased sales volume
related to the Company's integrated circuit, automated test
engineering and Alta products as well as increased Spectrum Services
consulting revenue.  The Alta product revenue increase was a result
of a full year of revenue related to the Comdisco business included
in 1994 as compared to 1993, which included revenue only from the
date of acquisition forward.  Spectrum Services consulting revenue
increased in 1994 due to increased demand for this business.  
Maintenance revenue increased $31.6 million for the year ended
December 31, 1994 to $159.2 million as compared to $127.6
million for the year ended December 31, 1993.  This increase was
attributable to an increase in the Company's installed base of products
as well as the Company's continued effort toward obtaining customer
renewals of maintenance coverage.

     Cost of revenue increased $5.3 million to $94.6 million for the
year ended December 31, 1994 as compared to $89.4 million for the
year ended December 31, 1993.  This increase was due to increased costs
associated with the continued expansion of the Spectrum Services
consulting business and increased costs related to the Alta division,
which were offset by cost reductions in occupancy due to the Company's
purchase of previously leased facilities and reduced cost of maintenance.

     Operating expenses increased $2.7 million to $290.4 million for
the year ended December 31, 1994 as compared to $287.7 million for the
year ended December 31, 1993.  This increase was due primarily to 
increased expenses related to the Alta operations and employee related
costs, offset by cost savings attributable to lower occupancy costs 
as well as reduced expenses attributable to lower capital equipment costs.

     Net income increased to $36.6 million, or $0.84 per share, for
the year ended December 31, 1994 as compared to a net loss of $12.8
million, or $0.30 per share, for the year ended December 31, 1993.

      The Company's cash and cash investments increased $13.6 million
during the year ended December 31, 1994 to $75.0 million at December
31, 1994, and its total assets increased $21.7 million during the year
ended December 31, 1994 to $361.0 million at December 31, 1994.
Working capital at December 31, 1994 was $27.5 million compared with
$105.0 million at December 31, 1993.  This decrease in working capital
was primarily due to an increase in notes payable of $23.7 million
related to the purchase of corporate facilities, an increase in 
deferred revenue of $23.1 million due to increased maintenance billings
and a $23.3 million decrease in accounts receivable due to 
improved days sales outstanding.
    
                     SELLING STOCKHOLDERS

     The following table sets forth certain information
known to the Company with respect to beneficial ownership of
the Company's Common Stock as of March 10, 1995 by each
Selling Stockholder named below.  All of the Selling
Stockholders except for Comdisco Systems and James Cherry
(the "Redwood Selling Stockholders") acquired the shares of
Common Stock offered hereby in connection with the Company's
acquisition of Redwood, in which the Redwood Selling

                     PLAN OF DISTRIBUTION

Comdisco Systems

     In connection with the Company's acquisition of the
Comdisco Systems Business, Comdisco Systems and its parent
corporation, Comdisco, Inc., entered into the Comdisco
Agreement with the Company pursuant to which Comdisco
Systems was granted certain registration rights with respect
to the Comdisco Shares.  On February 15, 1995, the Company
repurchased some of the warrants that had been issued to
Comdisco Systems in connection with the Company's
acquisition of the Comdisco Systems Business.  In connection
with such repurchase, the Company entered into the Comdisco
Repurchase Agreement, pursuant to which it granted Comdisco
certain registration rights with respect to the remaining
300,000 Comdisco Warrants.  The Registration Statement of
which this prospectus forms a part has been filed pursuant
to the Comdisco Agreement, as supplemented by the Comdisco
Repurchase Agreement.  In the Comdisco Agreement, as
supplemented by the Comdisco Repurchase Agreement, Comdisco
Systems agreed to sell any of the Comdisco Shares and
Comdisco Warrants offered by them pursuant to this
prospectus in accordance with the manner of sale provisions
set forth in Rule 144(f) promulgated under the Securities
Act or otherwise in customary brokerage transactions on the
NYSE and involving the payment by Comdisco Systems of
customary brokers' commissions in connection with such
sales.  No assurance can be given that Comdisco Systems will
sell any of the Comdisco Shares or Comdisco Warrants or that
Comdisco Systems will not sell such Comdisco Shares or
Comdisco Warrants in private transactions, pursuant to Rule
144 promulgated under the Securities Act or pursuant to
other transactions that are exempt from the registration
requirements of the Securities Act.

     Rule 144(f) permits sales in "brokers' transactions"
(described below) or to market makers, and provides that the
person selling the shares may not (1) solicit or arrange for
the solicitation of orders to buy the shares in anticipation
of or in connection with such transaction, or (2) make any
payment in connection with the offer or sale of the shares
to any person other than the broker who executes the order
to sell the securities.  In general, "brokers' transactions"
are ones in which the broker merely executes the sell order,
receives no more than the customary commissions and does not
solicit orders to buy the shares.

     To the best of the Company's knowledge, Comdisco
Systems has not entered into any agreement, arrangement or
understanding with any particular broker or market maker
with respect to the shares offered by it hereby.  The
Company does not know the identity of the brokers or market
makers which will participate in the offering.

     Pursuant to the Comdisco Agreement, as supplemented by
the Comdisco Repurchase Agreement, Comdisco Systems may not
sell the Comdisco Shares or Comdisco Warrants pursuant to
this prospectus without first submitting a written request
to the Company (the "Takedown Request") to sell at least
50,000 of the Comdisco Shares or Comdisco Warrants (or, if
less, any remaining shares or warrants held by Comdisco
Systems and registered hereunder).  The Company must notify
Comdisco Systems promptly following the receipt of the
Takedown Request whether it believes this prospectus should
be supplemented or amended prior to use in connection with
such sale of stock or warrants in which case the Company is
obligated to use all reasonable efforts to effectuate such
update as soon as possible.  Once the prospectus is
available for use, Comdisco Systems will have 15 business
days following notice of its availability within which to
sell the shares specified in its Takedown Request.  Comdisco
Systems may not offer or sell any Comdisco Shares or
Comdisco Warrants hereunder pursuant to a Takedown Request
during the period commencing with the 20th day before the
end of a fiscal quarter and ending with the earlier of the
20th day of the following month or the second trading day
following the public announcement of the Company's earnings
for the fiscal quarter in which the period commenced.  Under
certain circumstances, the Company is permitted to postpone
for a period of time the filing of an update to this
Prospectus, which would thereby delay the sale of Comdisco
Shares or Comdisco Warrants hereunder by Comdisco Systems.
During the period commencing June 11, 1995 and ending June
30, 1996, Comdisco Systems may not make a Takedown Request
or sell Comdisco Shares or Comdisco Warrants hereunder if
Comdisco Systems has not sold the full amount of shares or
warrants that it is then permitted to sell under the volume
limitations of Rule 144(e), unless the number of Comdisco
Shares to be sold is in excess of the number of shares
Comdisco Systems is then permitted to sell under Rule
144(e).  Under the Comdisco Agreement, as supplemented by
the Comdisco Repurchase Agreement, Comdisco Systems is
entitled to sell the Comdisco Shares or Comdisco Warrants
pursuant to this prospectus during the period beginning on
the effective date of the Registration Statement of which
this prospectus is a part and ending on June 30, 1996.

Redwood

     In connection with the Company's acquisition of
Redwood, the Company and Redwood entered into the
Reorganization Agreement, which provides that the shares of
the Company's Common Stock issued in connection with the
Company's acquisition of Redwood may not be sold during the
first year after such acquisition.  In addition, the
Company, Redwood and the Redwood Selling Stockholders
entered into a Registration Rights Agreement in connection
with the Redwood Merger (the "Redwood Registration
Agreement") which contemplates the registration of the
Redwood Shares for sale by the Redwood Selling Stockholders
during the period beginning August 31, 1995 and ending
August 31, 1996.  The Registration Statement of which this
prospectus forms a part has been filed pursuant to the
Redwood Registration Agreement.  In the Redwood Registration
Agreement, the Redwood Selling Stockholders agreed to sell
any of the shares offered by them pursuant to this
prospectus in accordance with the manner of sale provisions
set forth in Rule 144(f) promulgated under the Securities
Act (described above) or otherwise in customary brokerage
transactions on the NYSE or other public market on which the
Company's shares of Common Stock are traded.  No assurance
can be given that the Redwood Selling Stockholders will sell
any of the shares that are subject to this prospectus or
that the Redwood Selling Stockholders will not sell such
shares in private transactions, pursuant to Rule 144
promulgated under the Securities Act or pursuant to other
transactions that are exempt from the registration
requirements of the Securities Act.

     To the best of the Company's knowledge, the Redwood
Selling Stockholders have not entered into any agreement,
arrangement or understanding with any particular broker or
market maker with respect to the shares offered by them
hereby.  The Company does not know the identity of the
brokers or market makers which will participate in the
Offering.

     Beginning August 31, 1995, the Redwood Selling
Stockholders will be permitted to sell their Redwood Shares
pursuant to this prospectus during any of four 20-day
selling windows that will be designated by Irwin Federman as
representative of the Redwood Selling Stockholders or his
successor representative (the "Representative").  One 20-day
selling window is permitted each quarter from August 31,
1995 until the earlier of August 31, 1996 or the date on
which all Redwood Shares have been sold or may be sold under
Rule 144.  It is contemplated that the Redwood Selling
Stockholders will be notified by the Representative prior to
the beginning of each selling window, and such Redwood
Selling Stockholders will be requested to indicate how many
of their Redwood Shares they reasonably expect to sell
during that window.  The Representative will then notify the
Company as to when the Representative wishes the selling
window to commence (which must be at least five business
days after such notice) and the number of Redwood Shares
reasonably expected to be sold during the selling window.
Subject to limited rights to defer the commencement of the
selling window and rights to repurchase the Redwood Shares
as described below, the Company must acknowledge the
Representative's notice by confirming that the Redwood
Selling Stockholders may sell their Redwood Shares during
the selling window.  In such case, the Company must then
promptly prepare and file with the Commission any necessary
supplement or amendment to the prospectus prior to its use
and must notify the Representative when the prospectus is
available for use.  The Company will be permitted to defer
the commencement of the selling window for certain periods
of time and under certain circumstances.  Within five
business days after receipt of the Representative's notice
and prior to the commencement of the selling window, the
Company will have the right to repurchase the Redwood Shares
covered by the notice at a repurchase price equal to the
average closing price of the Company's Common Stock during
the five business days preceding the notice.  If this right
is not exercised, then, once the selling window commences,
the Redwood Selling Stockholders will be entitled to sell
over the NYSE (or any other public market in which the
Company's Common Stock is then traded), in customary
brokerage transactions, any or all their Redwood Shares that
were included in the notice.

Parsec

     In connection with the Company's acquisition of Parsec,
the Company and James Cherry entered into a Registration
Rights Agreement (the "Parsec Registration Agreement") which
contemplates the registration of the Parsec Shares for sale
by Mr. Cherry during the period beginning April 30, 1995 and
ending August 31, 1996.  The Registration Statement of which
this prospectus forms a part has been filed pursuant to the
Parsec Registration Agreement.  Pursuant to the Parsec
Registration Agreement, Mr. Cherry agreed to sell any of the
shares offered by him pursuant to this prospectus in
accordance with the manner of sale provisions set forth in
Rule 144(f) promulgated under the Securities Act (described
above) or otherwise in customary brokerage transactions on
the NYSE or other public market on which the Company's
shares of Common Stock are traded.  No assurance can be
given that Mr. Cherry will not sell such shares in private
transactions, pursuant to Rule 144 promulgated under the
Securities Act or pursuant to other transactions that are
exempt from the registration requirements of the Securities
Act.

     To the best of the Company's knowledge, Mr. Cherry has
not entered into any agreement, arrangement or understanding
with any particular broker or market maker with respect to
the shares offered by him hereby.  The Company does not know
the identity of the brokers or market makers which will
participate in the Offering.

     Beginning after April 30, 1995, Mr. Cherry will be
permitted to sell his Parsec Shares pursuant to this
prospectus when either the Redwood Selling Stockholders are
authorized to sell under the Redwood Registration Agreement
or Comdisco Systems is authorized to sell under the Comdisco
Agreement.  The conditions under which the Redwood Selling
Stockholders and Comdisco Systems are authorized to sell
under such agreements are set forth above.  In the event
that the Company receives a notice from the Representative
under the Redwood Registration Agreement or a Takedown
Request from Comdisco Systems, the Company is obligated to
give Mr. Cherry written notice of such notice or Takedown
Request within two business days of the Company's receipt of
such notice or Takedown Request.  Mr. Cherry shall have the
right to participate in the sale of shares contemplated by
such notice or Takedown Request if he gives the Company
written notice of his desire to participate and specifies
the number of shares to be sold within five business days of
his receipt of such notice or Takedown Request.  With the
exceptions set forth in this paragraph, Mr. Cherry's
registration rights are otherwise subject to the same
restrictions and limitations imposed upon the Redwood
Selling Stockholders, as described above.

                     DESCRIPTION OF WARRANTS

     The Comdisco Warrants held by Comdisco Systems entitle
Comdisco Systems, and its authorized assignees, to purchase
300,000 shares of the Company's Common Stock at an exercise
price of $14.50 per share, which may be paid in cash, by
check or by net exercise.  The Comdisco Warrants must be
exercised in increments of at least 50,000 shares and expire
on June 10, 2003.  The Comdisco Warrants contain provisions
for the adjustment of the exercise price and the number of
shares subject to the warrants upon the occurrence of
certain events, including stock splits, stock dividends,
reorganizations, reclassifications and mergers.  The
Comdisco Warrants may be assigned only in whole but not in
part prior to June 10, 1996 and thereafter may be assigned
in whole or in part, provided that no partial assignment may
be made of the right to purchase fewer than 100,000 shares
of Common Stock.  Any transferee of the Comdisco Warrants
must agree to the terms and conditions of such warrants.

                          LEGAL MATTERS

     The validity of the issuance of the shares of Common
Stock offered hereby will be passed upon for the Company by
Fenwick & West, Two Palo Alto Square, Suite 800, Palo Alto,

ITEM 14.  Other Expenses of Issuance and Distribution.

     The estimated expenses to be paid by the Registrant in
connection with this offering are as follows:


                                                     

Securities and Exchange Commission registration fee    $11,903

Legal fees and expenses                                 30,000
Miscellaneous                                            2,097

                                               Total  $ 94,000



ITEM 15.  Indemnification of Directors and Officers.

     As permitted by Section 145 of the Delaware General
Corporation Law, the Registrant's Certificate of
Incorporation includes a provision that eliminates the
personal liability of its directors for monetary damages for
breach or alleged breach of their duty of care.  The
Registrant also maintains a limited amount of director and
officer insurance.  In addition, as permitted by Section 145
of the Delaware General Corporation Law, the Bylaws of the
Registrant provide that:  (i) the Registrant is required to
indemnify its directors, officers and employees, and persons
serving in such capacities in other business enterprises
(including, for example, subsidiaries of the Registrant) at
the Registrant's request, to the fullest extent permitted by
Delaware law, including those circumstances in which
indemnification would otherwise be discretionary; (ii) the
Registrant is required to advance expenses, as incurred, to
such directors, officers and employees in connection with
defending a proceeding (except that it is not required to
advance expenses to a person against whom the Registrant
brings a claim for breach of the duty of loyalty, failure to
act in good faith, intentional misconduct, knowing violation
of law or deriving an improper personal benefit); (iii) the
rights conferred in the Bylaws are not exclusive and the
Registrant is authorized to enter into indemnification
agreements with such directors, officers and employees; (iv)
the Registrant is required to maintain director and officer
liability insurance to the extent reasonably available; and
(v) the Registrant may not retroactively amend the Bylaw
provisions in a way that is adverse to such directors,
officers and employees.

     The Registrant's policy is to enter into indemnity
agreements with each of its executive officers and directors
that provide the maximum indemnity allowed to officers and
directors by Section 145 of the Delaware General Corporation
Law and the Bylaws, as well as certain additional procedural
protections.  In addition, the indemnity agreements provide
that officers and directors will be indemnified to the
fullest possible extent not prohibited by law against all
expenses (including attorney's fees) and settlement amounts
paid or incurred by them in any action or proceeding,
including any derivative action by or in the right of the
Registrant, on account of their services as directors or
officers of the Registrant or as directors or officers of
any other company or enterprise when they are serving in
such capacities at the request of the Registrant.  No
indemnity will be provided, however, to any director or
officer on account of conduct that is adjudicated to be
knowingly fraudulent, deliberately dishonest or willful
misconduct.  The indemnity agreements also provide that no
indemnification will be available if a final court
adjudication determines that such indemnification is not
lawful, or in respect of any accounting of profits made from
the purchase or sale of securities of the Registrant in
violation of Section 16(b) of the Exchange Act.
     
     The indemnification provision in the Bylaws, and the
indemnity agreements entered into between the Registrant and

ITEM 17.  Undertakings.

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

          (2)  That, for the purpose of determining any
liability under the Securities Act, each post-effective
amendment shall be deemed a new registration statement
relating to the securities offered therein, and the offering
of the 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 that
is incorporated by reference in this registration statement
shall be deemed to be a new registration statement relating
to the securities offered therein, and the offering of such
securities at that time shall be deemed to be the initial
bona fide offering thereof.

     Insofar as indemnification for liabilities arising
under the Securities Act may be permitted to directors,
officers and controlling persons of the Registrant pursuant
to the provisions described under Item 15 above, or
otherwise, the Registrant has been advised that in the
opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the
Securities Act and is, therefore, unenforceable.  In the
event that a claim for indemnification against such
liabilities (other than the payment by the Registrant of
expenses incurred or paid by a director, officer or
controlling person of the Registrant in the successful
defense of any action, suit or proceeding) is asserted by
such director, officer or controlling person in connection
with the securities being registered, the Registrant will,
unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed
in the Securities Act and will be governed by the final
adjudication of such issue.

SIGNATURES
   
     Pursuant to the requirements of the Securities Act, the
Registrant certifies that it has reasonable grounds to
believe that it meets all of the requirements for filing on
Form S-3 and has duly caused this Amendment No. 2 to the
Registration Statement to be signed on its behalf by the
undersigned, thereunto duly authorized, in the City of San
Jose, State of California, on the 27th day of March, 1995.
