                                  THE COMPANY
 
     Media Vision Technology Inc. filed for protection under Chapter 11 of the
Bankruptcy Code in July 1994. A Plan of Reorganization (POR) was approved and
was declared effective in December 1994. The POR resulted in a new operating
entity. Prior to August 1995, the Company designed, developed, and marketed
 
                                        2
<PAGE>   5
 
   
multimedia add-in subsystems that added enhanced sound capabilities to personal
computers, through electronics retail and distributor channels. In August 1995,
the Company announced its intended divestiture of retail operations in order to
concentrate solely on the development of its audio semiconductor technology and
implement a business model based upon the sale of audio semiconductors and
licensing of semiconductor technology. In November 1995, the Company announced
that it was changing its name to Aureal Semiconductor and has been doing
business as Aureal Semiconductor since then. The Company changed its name to
Aureal Semiconductor Inc. on May 8, 1996 pursuant to a vote of its stockholders
at the 1996 Annual Meeting.
    
 
     Aureal designs, develops and markets advanced audio solutions for
multimedia desktop PC and add-in sound card manufacturers. Aureal believes it
will be one of the first suppliers of audio components that will offer advanced
audio synthesis and true positional 3-D audio for the PC marketplace. The
Company's initial products are expected to implement true positional 3-D audio,
Windows Direct Sound acceleration, digital mixing and a wide range of other
sound-processing effects and algorithms. Future products include mixed-signal,
multi-synth solutions which incorporate both wavetable synthesis and waveguide
physical modeling technologies. The Company intends to promote true positional
3-D audio and over time surpass current synthesis solutions and establish
waveguide physical modeling synthesis as a new standard in PC audio technology.
 
   
     Aureal was incorporated as Media Vision Inc. in California in May 1990 and
was reincorporated in Delaware as Media Vision Technology Inc. in November 1992.
The Company emerged from reorganization under Chapter 11 of the U.S. Bankruptcy
code on December 30, 1994 and in November 1995 changed its name to Aureal
Semiconductor Inc. The Company's stockholders approved the name change on May 8,
1996. Unless the context otherwise requires, "Aureal" and the "Company" refer to
Aureal Semiconductor Inc., a Delaware corporation, and its predecessor and
subsidiary. The Company's principal executive offices are located at 4245
Technology Drive, Fremont, California 94538, and its telephone number is (510)
252-4245. See "INFORMATION INCORPORATED BY REFERENCE."
    
 
   
                              RECENT DEVELOPMENTS
    
 
   
     On May 7, 1996, Aureal entered into an Agreement and Plan of Reorganization
with Crystal River Engineering, Inc., a California corporation ("CRE"), and
Aureal Acquisition Corporation, a California corporation and a wholly-owned
subsidiary of the Company ("Sub"), pursuant to which Sub was merged with and
into CRE (the "Merger"). CRE is a leading developer of true positional 3D audio
technology. The terms of the Merger provided that the Company purchase each
outstanding share of common stock of CRE at a price per share of $8.30 and
assume each outstanding and unexercised option for CRE common stock and convert
such option into an option to purchase shares of the Company's Common Stock. The
total cash payment by the Company for CRE stock was $2,879,967.00 and the total
number of shares reserved for conversion of CRE options into Aureal Common Stock
was 2,644,840. In addition, bonus and incentive payments totaling $846,000.00
have been paid, or are expected to be paid by the Company over the next 18
months to the former CRE shareholders. The Company filed the Reorganization
Agreement as Exhibit 5.1 to its Form 8-K on May 22, 1996.
    
 
   
     CRE, founded in 1987, develops and markets interactive, positional 3D audio
technology and related systems under the AudioRealty brand name. Using
conventional stereo speakers or headphones, CRE's technology allows sounds to be
dynamically positioned in the three-dimensional space surrounding a listener.
CRE's first product was the NASA-commissioned Convolvotron, the world's first
real-time 3D sound simulator. Since then, CRE's products have been installed in
many psycho-acoustic research labs, commercial flight and driving simulators,
and advanced virtual reality systems. Over the last 18 months, CRE has worked
with industry leaders to establish the standards and requirements that are
expected to bring advanced, interactive 3D audio from today's high-end
applications to mainstream Internet, multimedia and electronic gaming platforms.
    
 
   
     On June 11, 1996, the Company announced that it had signed a Common Stock
Purchase Agreement for the sale of 8,888,888 shares of Aureal Common Stock at a
price of $1.35 per share for total proceeds of
    
 
                                        3
<PAGE>   6
 
   
approximately $12 million. The participants in this private placement included
The TCW Group, Inc., DDJ Capital Management, LLC and Appaloosa Management, L.P.
The Company expects to use the proceeds from this private placement to pay down
its outstanding debt.
    
 
                          FORWARD LOOKING INFORMATION

herein, contains forward-looking statements within the meaning of Section 27A of

and 1993, the Company's retail products business operations generated
substantial losses, which in the aggregate exceeded $238 million. In August
1995, the Company announced its intended divestiture of retail operations in
order to concentrate solely on the development of its audio semiconductor
technology and to implement a business model based upon the sale of audio
semiconductors and on licensing of semiconductor technology. The Company expects
that for 1996, it will continue to sustain losses from its operations and does
not expect to be cash flow positive from operations during 1996. Losses of
$103.8 million sustained during 1995, including recognition of restructuring
charges of $61.6 million pursuant to the Company's decision to exit the retail
products business, generated stockholders' deficit of $23.8 million as of
December 31, 1995. The restructuring charge recognition included a write-down of
$30.5 million of the reorganization asset generated upon exit from Chapter 11
bankruptcy proceedings on December 30, 1994.
    
 
   
     In addition, at December 31, 1995, current liabilities exceeded current
assets by approximately $5.5 million. The Company anticipated funding the
shortfall through equity financings (received in February and March, 1996) as
well as potentially utilizing the $2.45 million remaining available under its
line of credit.
    
 
   
     In prior years, substantially all of the Company's revenues have been
generated from its retail products business. The Company now anticipates its
revenues to be derived from sales of products based upon, or licensing of the
Company's audio technologies, including True Positional 3D Audio and
parameterized physical modeling of sound. This is effectively a new business
venture for the Company with all the attendant risks associated thereto
including those discussed in further detail below. There can be no assurance
that the Company will be able to achieve profitability. See "INFORMATION
INCORPORATED BY REFERENCE."
    
 
DELIVERY OF PRODUCTS
 
     Although the Company has prototypes of its ASP301 chip which are
functional, it still has numerous technologically challenging silicon and
software obstacles to overcome in order to produce a viable product based on its
technology. The Company must complete the design and manufacture a custom PCI
interface chip which is required as part of the ASP301 chipset. In addition, the
Company must develop, either internally or through third party subcontracting,
various complete software device drivers, physical models and wavetable
synthesis as well as a variety of application interface software. The Company is
only in the design phase of its other products. There can be no assurance that
the Company will be successful in completion of these projects in a timely
manner, if at all. See "INFORMATION INCORPORATED BY REFERENCE."

NEW TECHNOLOGY
 
     Although audio physical modeling technology is becoming more widely used in
the music industry, no other semiconductor company has announced a product based
in large part on this technology. In addition, game and application developers
have not yet built capabilities within their applications to take advantage of
physical modeling technology. There can be no assurance that the Company will be
able to create a market for its form of advanced audio synthesis.
 
RETAIL BUSINESS LIABILITY
 
   
     In February 1996, the Company sold the Media Vision brand name and other
assets (primarily specific product trademarks, product designs and inventories
of certain products designated to fulfill warranty claims -- all of diminimus
book value) to a third party. The buyer is obligated to satisfy retail customer
service, warranty and technical support obligations arising subsequent to the
date of the agreement. The Company had entered into agreements related to
expenses associated with its prior retail business including minimum purchase
commitments for supplies, components and services. The Company believes it has
accrued adequate reserves for liabilities associated with those prior retail
obligations. On December 31, 1995 (as discussed in footnote 10 to the financial
statements in the Company's Form 10-K), the remaining reserves related to
exiting the retail products business totalled approximately $2.0 million. There
can be no assurance that the Company's estimates will be adequate to cover
liabilities which may arise from these obligations.
    
 
DEPENDENCE ON FOUNDRIES AND OTHER THIRD PARTIES
 
   
     The Company relies on independent foundries to manufacture all of its
semiconductor products. The Company has shifted its strategy to pursue a
business model focused entirely on the development and sales of audio solutions
including software and semiconductor products. The Company's success in
implementing this strategy will depend in large part upon its ability to
establish reliable arrangements with outside semiconductor manufacturers or
"foundries" for the manufacture of its semiconductor products. In recent
periods, a substantial majority of the Company's chip and chip set products have
been manufactured by one foundry. This foundry has indicated that it will
severely limit its production of these products in the near future. The Company
has arranged for this foundry to manufacture a limited number of prototypes of
certain of the Company's products under development. The Company has transferred
its designs from this foundry located in Taiwan to another foundry with a
similar fabrication process also located in Taiwan. This other Taiwanese foundry
has indicated it will be capable of meeting the Company's production
requirements for its future products; however, such arrangement is on a purchase
order basis and may be canceled at any time. The Company is engaged in
discussions with other foundries with respect to potential arrangements to
manufacture the Company's semiconductor products. There can be no assurance that
the Company will be able to obtain any such arrangement, or if it does obtain
such an arrangement, it does so on terms favorable to the Company. To the extent
the Company is unable to obtain suitable foundry arrangements, the Company's
business, financial condition and results of operations could be materially and
adversely affected. Further, to the extent the Company obtains an arrangement
with a foundry as a sole supplier of one or more of the Company's products, any
significant interruption in the supply of such product from the foundry could
have a material adverse effect on the Company's business, financial condition
and results of operations.
    
 
   
     Recent increases in semiconductor demand have reduced available foundry
capacity worldwide, which could adversely affect the Company's ability to meet
its manufacturing needs. To address foundry capacity constraints, other
semiconductor suppliers that rely on third party foundries have utilized various
arrangements, including equity investments in or loans to independent wafer
manufacturers in exchange for guaranteed production capacity, joint ventures to
own and operate foundries, or "take or pay" contracts that commit a company to
purchase specified quantities of wafers over extended periods. While the Company
is not currently a party to any such arrangements, it may be necessary or
advantageous for the Company to enter into such arrangements in the future and
there can be no assurance that it will be successful in this regard. Any such
arrangements could require the Company to commit substantial capital and grant
licenses to its technology. The need to commit substantial capital may require
the Company to seek additional debt or equity financing, which could result in
dilution to the Company's stockholders. There can be no assurance that such
    
 
                                        5
<PAGE>   8
 
additional financing, if required, will be available when needed or, if
available, on terms acceptable to the Company.
 
   
     The manufacture of semiconductors is a highly complex and precise process.
Minute levels of contaminants in the manufacturing environment, defects in the
masks used to print circuits on a wafer, difficulties in the fabrication process
or other factors can cause a substantial percentage of wafers to be rejected or
a significant number of die on each wafer to be nonfunctional. Many of these
problems are difficult to diagnose, time-consuming or expensive to remedy. The
Company's products are particularly complex and difficult to manufacture. Due to
its integration of both analog logic functions and digital logic function in its
semiconductor products, special fabrication processes are required to achieve
acceptable yields for mixed signal devices (devices integrating both analog and
digital components). There can be no assurance that the Company's foundries will
not experience irregularities or adverse yield fluctuations in their
manufacturing processes. Any yield or other production problems or shortages of
supply experienced by the Company or its foundries could have a material adverse
effect on the Company's business, financial condition and results of operations.
See "INFORMATION INCORPORATED BY REFERENCE."
    
 
DEPENDENCE ON SINGLE PRODUCT LINE AND PC INDUSTRY
 
   
     Most of the Company's initial products will be sold for use with multimedia
desktop PCs. Aureal's audio semiconductors are being designed to be used in
motherboards by multimedia PC original equipment manufacturers ("OEMs") or on
add-in sound cards manufactured by OEMs or PC peripheral suppliers. Therefore,
the Company is heavily dependent on the continued growth of the markets for
multimedia desktop PCs and multimedia applications utilizing high quality audio.
While the market for multimedia PCs has recently experienced substantial growth,
the overall PC industry has historically been cyclical, and there can be no
assurance that this growth will continue in future periods. A decline in demand
in the PC industry would result in a corresponding decline in demand for the
Company's products, which would have a material adverse effect on the Company's
business, financial condition and operating results. See "INFORMATION
INCORPORATED BY REFERENCE."
    
 
NEW MANAGEMENT TEAM; DEPENDENCE ON PERSONNEL
 
   
     Only one of the Company's current officers served as an officer of the
Company prior to March 1995. All of the Company's current Board of Directors
were elected subsequent to the Company's emergence from bankruptcy in December
1994. The Company's management team and Board of Directors face significant
challenges in delivering state of the art products in a cost effective and
profitable manner. Due to the short operating history of the Company's current
management and Board of Directors, there can be no assurance that the management
team and Board of Directors can successfully manage the Company's rapidly
evolving business.
    
 
   
     The Company's success also depends to a significant extent upon the
continued service of key engineering, marketing, sales and management personnel.
In connection with the Company's acquisition of CRE, the Company entered into an
employment agreement with Mr. Scott Foster, Aureal's new Chief Technology
Officer. The employment agreement provides that Mr. Foster shall be employed by
the Company for one year, and that in certain circumstances, if Mr. Foster's
employment with Aureal terminates, Mr. Foster will not compete with the Company
for a period of two years. The Company's other officers all have signed standard
confidentiality and nondisclosure agreements. The Company's employees may
voluntarily terminate their employment with the Company at any time. The
competition for such employees is intense, and the loss of the services of such
employees could have a material adverse effect on the Company's business,
financial condition and results of operations. See "INFORMATION INCORPORATED BY
REFERENCE."
    
 
POTENTIAL FLUCTUATIONS IN QUARTERLY RESULTS
 
   
     The Company's operating results are subject to quarterly and other
fluctuations due to a variety of factors, including the gain or loss of
significant customers, increased competitive pressures, the timing of new
product announcements and introductions by the Company or its competitors and
market acceptance of new or
    
 
                                        6
<PAGE>   9
 
   
enhanced versions of the Company's and its customers products. Other factors
include the availability of foundry capacity, fluctuations in manufacturing
yields, availability and cost of raw materials, changes in the mix of products
sold, the cyclical nature of both the semiconductor industry and the market for
PCs, seasonal customer demand, the timing of significant orders, potential
significant increases in expenses associated with the expansion of operations,
and changes in pricing policies by the Company, its competitors or its
suppliers. The Company's operating results could also be adversely affected by
economic conditions generally in various geographic areas where the Company or
its customers do business, or order cancellations or rescheduling. These factors
are difficult to forecast, and these or other factors could materially adversely
affect the Company's quarterly or annual operating results. There can be no
assurance as to the level of sales or earnings that may be attained by the
Company in any given period in the future. See "INFORMATION INCORPORATED BY
REFERENCE."
    
 
COMPETITION; PRICING PRESSURES
 
   
     The markets in which the Company competes are intensely competitive and are
characterized by rapid technological change, price declines and rapid product
obsolescence. The Company expects competition to increase in the future from
existing competitors and from other companies that may enter the Company's
existing or future markets with products that may be less costly or provide
higher performance or additional features. The Company competes with
semiconductor manufacturers offering multiple function chip solutions and single
chip solutions. The Company anticipates that it will continue to compete with
such third parties, and that competitors may offer more highly integrated
solutions in the future. The Company is unable to predict the timing and nature
of any such competitive product offerings. The announcement and commercial
shipment of competitive products could adversely affect sales of the Company's
products and may result in increased price competition that would adversely
affect the prices of the Company's products and margins. In general, product
prices in the semiconductor industry have decreased over the life of a
particular product. The markets for most of the applications for the Company's
products, particularly the PC market, are characterized by intense price
competition. The willingness of prospective customers to design the Company's
products into their products depends to a significant extent upon the ability of
the Company to price its products at a level that is cost-effective for such
customers. As the markets for the Company's products mature and competition
increases, the Company anticipates that prices for its products will continue to
decline. If the Company is unable to reduce its costs sufficiently to offset
declines in product prices or is unable to introduce new, higher performance
products with higher product prices, the Company's business, financial condition
and results of operations could be materially adversely affected.
    
 
   
     The Company's existing and potential competitors consist principally of
large domestic and international companies that have substantially greater
financial, manufacturing, technical, marketing, distribution and other
resources, greater intellectual property rights, broader product lines and
longer-standing relationships with customers than the Company. The Company's
competitors also include a number of emerging companies. The Company's principal
existing and potential competitors include, but are not limited to, Chromatic
Research, Cirrus Logic, Inc., Creative Technology Ltd., ESS Technology, Inc.,
OPTi, Inc. and Yamaha. Certain of the Company's current and potential
competitors maintain their own semiconductor foundries and may therefore benefit
from certain capacity, cost and technical advantages. The Company believes that
its ability to compete successfully depends on a number of factors, both within
and outside of its control, including the price, quality and performance of the
Company's and its competitors products, the timing and success of new product
introductions by the Company, its customers and its competitors, the emergence
of new multimedia PC standards, the development of technical innovations, the
ability to obtain adequate foundry capacity and sources of raw materials, the
efficiency of production, the rate at which the Company's customers design the
Company's products into their products, the number and nature of the Company's
competitors in a given market, the assertion of intellectual property rights and
general market and economic conditions. There can be no assurance that the
Company will be able to compete successfully in the future.

     Each successive generation of microprocessors has provided increased
performance, which could in the future result in a microprocessor capable of
performing audio functions, thereby eliminating the need for the Company's
products. In this regard, Intel Corporation has developed Native Signal
Processing ("NSP") capability for use in conjunction with its Pentium
microprocessors, and is promoting the processing power of the Pentium for data
and signal intensive functions such as graphics acceleration and other
multimedia functions. Intel's NSP's strategy involves executing such signal
processing on the host processor rather than allowing such processing of audio
or graphic functions to occur on a peripheral component such as the Company's
product. At this time the processing power required to execute high quality
video, graphics, and audio simultaneously and all the other functions which the
host processor does, has not been achieved by Intel's products. There can be no
assurance that the increased capabilities of microprocessors will not adversely
affect demand for the Company's products. See "INFORMATION INCORPORATED BY
REFERENCE."
    
 
IMPORTANCE OF NEW PRODUCTS AND TECHNOLOGICAL CHANGE
 
   
     The markets for the Company's products are characterized by evolving
industry standards, rapid technological change and product obsolescence. The
Company's success is highly dependent upon the successful development and timely
introduction of new products at competitive price and performance levels. The
success of new products depends on a number of factors, including timely
completion of product development, market acceptance of the Company's and its
customers new products, securing sufficient foundry capacity for volume
manufacturing of wafers, achievement of acceptable wafer fabrication yields by
the Company's independent foundries and the Company's ability to offer new
products at competitive prices. Incorporating the Company's new products into
its OEM customers new product designs requires the anticipation of market trends
and performance and functionality requirements of OEMs, the development and
productions of products that meet the timing and pricing requirements of OEMs
and that can be tested and be available in a timely manner consistent with the
OEM's development and production schedule. Accordingly, in selling to OEMs, the
Company can often incur significant expenditures in advance of volume sales of
new products, if any. There can be no assurance that the Company will be able to
successfully identify new product opportunities, develop and market new
products, achieve design wins or respond effectively to new technological
changes or product announcements by others. A failure in any of these areas
would have a material adverse effect on the Company's business, financial
condition and results of operation.
    
 
FACTORS INHIBITING TAKEOVER
 
   
     The Company is subject to the provisions of Section 203 of the Delaware
General Corporation Law, which imposes certain restrictions on the ability of a
third party to effect an unsolicited change in control of the Company. In
addition, the Company's Certificate of Incorporation does not provide for
cumulative voting in the election of directors, and certain provisions of the
Company's Certificate of Incorporation and By-Laws, including the provisions
which divide the Board into three separate classes, may have the effect of
delaying or preventing changes in control or management of the Company. While
the Company believes these restrictions are in the best interests of the Company
and its stockholders, these restrictions could adversely affect the market price
of the Company's Common Stock.
    
 
UNCERTAINTY OF TRADING MARKET FOR COMMON STOCK
 
     The Company's old common stock traded on the Nasdaq National Market from
November 11, 1992, the date of its initial public offering, until August 18,
1994, when it was listed on the Nasdaq Small Cap Market. The Old Common Stock
was delisted from the Nasdaq Small Cap Market on December 9, 1994 and was
canceled on December 30, 1994 pursuant to the Plan of Reorganization ("POR").
Since being issued pursuant to the POR, on December 30, 1994, the Common Stock
has only traded on Nasdaq's OTC Bulletin Board and the trading volume has been
very light. The Company does not currently meet the requirements of the Nasdaq
National Market or other national stock exchanges. There can be no assurance
that the Common Stock will meet these listing requirements and that it will be
accepted for trading on such national stock exchanges. There can be no assurance
as to the liquidity of any markets that may develop for the Common
 
                                        8

Stock. The trading price of the Common Stock may be influenced by the volume and
liquidity of the market for the Common Stock. In addition, the Common Stock
being offered pursuant to this Prospectus represents approximately seventy-one
percent (71%) of the Company's total outstanding securities. Offering such a
large percentage of the Company's total outstanding securities may have an
adverse effect on the market for the Company's securities. See "INFORMATION

                              PLAN OF DISTRIBUTION
 
   
     This public offering, which is not being underwritten, relates to
27,682,716 shares of Common Stock of the Company offered from time to time by
any or all of the Selling Stockholders who received such shares pursuant to (1)
a bankruptcy reorganization, (2) Common Stock Purchase Agreements, by and among
the Company and certain of the Selling Stockholders or (3) warrants issued by
the Company. The Selling Stockholders hold certain registration rights pursuant
to a Registration Rights Agreement by and among the Company and the Selling
Stockholders. All shares issued to date have been issued pursuant to an
exemption from the registration requirements of the Securities Act provided by
Section 4(2) thereof.
    
 
     The Company has been advised by the Selling Stockholders that they and any
person receiving shares from the Selling Stockholders in the form of a bona fide
gift or distribution to a limited partner of a Selling Stockholder (a "Donee")
intend to sell all or a portion of the shares offered hereby from time to time
in the over-the-counter market and that sales will be made at prices prevailing
at the times of such sales. The Selling Stockholders and any Donee may also make
private sales directly or through a broker or brokers, who may act as agent or
as principal. In connection with any sales, the Selling Stockholders, any Donee
and any brokers participating in such sales may be deemed to be underwriters
within the meaning of the Securities Act. The Company will receive no part of
the proceeds of sales made hereunder.
 
     Any broker-dealer participating in such transactions as agent may receive
commissions from the Selling Stockholders and any Donee (and, if they act as
agent for the purchaser of such shares, from such purchaser). Usual and
customary brokerage fees will be paid by the Selling Stockholders and any Donee.
Broker-dealers may agree with the Selling Stockholders to sell a specified
number of shares at a stipulated price per share, and, to the extent such a
broker-dealer is unable to do so acting as agent for the Selling Stockholders
and any Donee, to purchase as principal any unsold shares at the price required
to fulfill the broker-dealer commitment to the Selling Stockholders and any
Donee. Broker-dealers who acquire shares as principal may thereafter resell such
shares from time to time in transactions (which may involve crosses and block
transactions and which may involve sales to and through other broker-dealers,
including transactions of the nature described above) in the over-the-counter
market, in negotiated transactions or otherwise at market prices prevailing at
the time of sale or at negotiated prices, and in connection with such resales
may pay to or receive from the purchasers of such shares commissions computer as
described above.
 
     The Company has advised the Selling Stockholders that the anti-manipulative
Rules 10b-6 and 10b-7 under the Exchange Act may apply to their sales in the
market, has furnished each Selling Stockholder with a copy of these Rules and
has informed them of the need for delivery of copies of this Prospectus. The
Selling Stockholders or any Donee may indemnify any broker-dealer that
participates in transactions involving the sale of the shares against certain
liabilities, including liabilities arising under the Securities Act. Any
commissions paid or any discounts or concessions allowed to any such
broker-dealers, and any profits received on the resale of such shares, may be
deemed to be underwriting discounts and commissions under the Securities Act if
any such broker-dealers purchase shares as principal.
 
     Upon notification by a Selling Stockholder or any Donee to the Company that
any material arrangement has been entered into with a broker-dealer for the sale
of shares through a cross or block trade, to the extent required, a supplemental
prospectus will be filed under Rule 424(c) under the Securities Act setting
forth the name of the participating broker-dealer(s), the number of shares
involved, the price at which such shares were sold by the Selling Stockholder or
any Donee, the commissions paid or discounts or concessions allowed by the
Selling Stockholder or any Donee to such broker-dealer(s), and where applicable,
that such broker-dealer(s) did not conduct any investigation to verify the
information set forth in this Prospectus.
 
     Any securities covered by this Prospectus which qualify for sale pursuant
to Rule 144 under the Securities Act may be sold under that Rule rather than
pursuant to this Prospectus.
 
     There can be no assurance that any of the Selling Stockholders or any Donee
will sell any or all of the shares of Common Stock offered by them hereunder.

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     Section 145(a) of the Delaware General Corporation Law (the "DGCL")
provides in relevant part that "a corporation shall have power to indemnify any
person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative (other than an action by or in the
right of the corporation) by reason of the fact that he is or was a director,
officer, employee or agent of the corporation, or is or was serving at the
request of the corporation as a director, officer, employee or agent of another
corporation, partnership, joint venture, trust or other enterprise, against
expenses (including attorneys' fees), judgments, fines and amounts paid in
settlement actually and reasonably incurred by him in connection with such
action, suit or proceeding if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
corporation, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful." With respect to
derivative actions, Section 145(b) of the DGCL provides in relevant part that
"[a] corporation may indemnify any person who was or is a party or is threatened
to be made a party to any threatened, pending or completed action or suit by or
in the right of the corporation to procure a judgment in its favor [by reason of
his service in one of the capacities specified in the preceding sentence]
against expenses (including attorneys' fees) actually and reasonably incurred by
him in connection with the defense or settlement of such action or suit if he
acted in good faith and in a manner he reasonably believed to be in or not
opposed to the best interests of the corporation and except that no
indemnification shall be made in respect of any claim, issue or matter as to
which such person shall have been adjudged to be liable to the corporation
unless and only to the extent that the Court of Chancery or the court in which
such action or suit was brought shall determine upon application that, despite
the adjudication of liability but in view of all the circumstances of the case,
such person is fairly and reasonably entitled to indemnity for such expenses
which the Court of Chancery or such other court shall deem proper."
 
   
     Article SIXTH of the Company's Amended and Restated Certificate of
Incorporation (the "Certificate of Incorporation") provides generally that to
the fullest extent permitted by the DGCL, no director of the Company shall be
personally liable to the Company or its stockholders for monetary damages for
breach of fiduciary duty as a director, except for liability (a) for any breach
of the director's duty of loyalty to the Company or its stockholders, (b) for
acts or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (c) under Section 174 of the DGCL; or (d) for any
transaction from which the director derived any improper personal benefit. The
Certificate of Incorporation also provides that no amendment or repeal of such
provision shall apply to or have any effect on the right to indemnification
permitted thereunder with respect to claims arising from acts or omissions
occurring in whole or in part before the effective date of such amendment or
repeal whether asserted before or after such amendment or repeal. In
    
 
                                      II-1
<PAGE>   18
 
   
addition, Article VIII of the Company's Bylaws provides that the Company shall
indemnify its directors, officers, employees and agents to the fullest extent
permitted by the DGCL. The indemnification provided by the Company's Certificate
of Incorporation and Bylaws does not eliminate monetary liability of the
Company's officers, directors, employees and agents under the federal securities
laws.

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;
 
          (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 paragraphs 1(i) and 1(ii) do not apply if the
information required to be included in a post-effective amendment by those
paragraphs 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 of 1933, 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.
 
                                      II-2
<PAGE>   19
 
   
     4. 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.
    
 
     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 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 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 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.

     Re: Aureal Semiconductor Inc. Registration Statment on Form S-3
Registration No. 333-3870
    
 
   
Ladies and Gentlemen:
    
 
   
     This opinion is furnished to you in connection with a Registration
Statement on Form S-3 (the "Registration Statement"), filed with the Securities
and Exchange Commission (the "Commission") under the Securities Act of 1933, as
amended, for the registration of 27,682,716 shares of Common Stock (the "Common
Stock"), par value $0.001 per share (the "Shares"), of Aureal Semiconductor Inc.
(the "Company").
    
 
   
     We have acted as counsel for the Company in connection with the
registration of such Shares. We have examined signed copies of the Registration
Statement and all exhibits thereto as filed with the Commission.
    
 
   
     Based upon representations of certain officers of the Company as to the
receipt of full consideration and assuming the conversion of certain warrants in
accordance with their terms, we are of the opinion that the shares of Common
Stock to be registered will be validly issued, fully paid and non-assessable.
    
 
   
     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,
    
 
   
                                          /s/  Gray Cary Ware & Freidenrich

         2.       Closing Dates; Delivery.

                  2.1 Closing Date. The closing of the purchase and sale of the

standing under the laws of the State of Delaware and has all requisite corporate
power and authority to carry on its business as now conducted and as proposed to
be conducted. The Company is presently qualified, licensed or domesticated as a
foreign corporation or partnership in all jurisdictions in which the failure to

consequences to the Company or its business. Copies of the Company's Certificate
of Incorporation, Bylaws and minutes and consents of its stockholders and Board
of Directors will be provided to the Purchasers or their special counsel upon
request.

                  3.2 Corporate Power. The Company has now, or will have at the
Closing Date, all requisite legal and corporate power to enter into this
Agreement and all other agreements contemplated hereby, to sell the Securities
hereunder, and to carry out and perform its obligations under the terms of this
Agreement and all other agreements contemplated hereby. This Agreement and all

conveyance, moratorium, usury, reorganization, and other laws of general
application affecting the enforcement of creditors' rights.

                  3.3 Capitalization. The authorized capital stock of the
Company is 100,000,000 shares of Common Stock. The Company has reserved, up to
twenty percent (20%) of the then fully diluted Common Stock (including

there are issued and outstanding 30,000,000 shares of the Company's Common
Stock. All such issued and outstanding shares have been duly authorized and
validly issued, are fully paid and nonassessable and were issued in compliance
with all applicable state and federal laws concerning the issuance of
securities. Except for (i) 7,500,000 shares of Common Stock which are currently
reserved under the Company's 1994 Stock Option Plan and the Company's 1995 Stock

consultants and members of the Board of Directors of the Company (options for
approximately 6,005,162 shares are currently outstanding under the Plan), (ii)
options to purchase 2,644,845 shares of the Company's Common Stock which were
assumed pursuant to the acquisition of Crystal River Engineering, Inc., (iii) an
agreement between the Company and Hambrecht & Quist LLC ("H&Q") to issue to H&Q
a warrant to purchase 50,000 shares of the Company's Common Stock, and (iii) a
warrant to Financing For Science International to purchase 50,000 shares of the
Company's Common Stock, there are no outstanding rights, options, warrants,
conversion rights or agreements for the purchase or acquisition from the Company
of any shares of its capital stock. The Company is not a party or subject to any
agreement or understanding between any persons or entities which affects or
relates to the voting or giving of written consents with respect to any
securities or by any director of the Company.

                  3.4 Line of Credit. The Company has agreed to reduce its line
of credit with TCW from $22.0 million to $20.0 million effective upon the
closing of this transaction. All net proceeds from this transaction are
anticipated to be used to pay



                                        2

down the line of credit which will remain available for further reborrowing
through its current termination date of March 31, 1998.

                  3.5      Authorization.

                  (a) All corporate, federal and state action on the part of the
Company, its officers, directors and stockholders necessary for the sale and
issuance of the Securities pursuant hereto and the performance of the Company's
obligations hereunder or contemplated hereby has been taken or will be taken
prior to the Closing.

                  (b) The Securities, when issued in compliance with the
provisions of this Agreement, will be validly issued, fully paid and
nonassessable, and will be free of any liens or encumbrances; provided, however,
that the Securities may be subject to restrictions on transfer under state
and/or federal securities laws as set forth herein, and as may be required by
future changes in such laws.

                  (c) No person has any right of first refusal or any preemptive
rights in connection with the issuance of the Securities.

                  3.6 Patents, Trademarks, etc. Except as set forth in Exhibit
B, the Company owns and possesses or is licensed under all patents, patent
applications, licenses, trademarks, trade names, brand names, inventions,
processes, formulae and copyrights necessary for the operation of the business
of the Company as now conducted and as proposed to be conducted with no
infringement of or conflict with the rights of others. Except as contemplated in
this Agreement, there are no outstanding options, licenses, or agreements of any
kind relating to the foregoing, nor is the Company bound by or a party to any
other options, licenses or agreements of any kind with respect to the patents,
trademarks, service marks, trade names, copyrights, trade secrets, licenses,
information, proprietary rights and processes of any other person or entity. The
Company has not received any communications alleging that it has violated or, by
conducting its business as proposed, would violate any of the patents,
trademarks, service marks, trade names, copyrights or trade secrets or other
proprietary rights of any other person or entity. The Company is not aware that
any of its employees are obligated under any contract (including licenses,
covenants or commitments of any nature) or other agreement, or subject to any
judgment, decree or order of any court or administrative agency, that would
interfere with the use of his or her best efforts to promote the interests of
the Company or that would conflict with the Company's business as proposed to be
conducted or that would prevent any such employee from assigning inventions to
the Company. Neither the execution nor delivery of this Agreement, nor the
carrying on of the Company's business as proposed, will, to the best of the
Company's knowledge, conflict with or result in a breach of the terms,
conditions or provisions of, or constitute a default under, any contract,
covenant or instrument under which any of such employees is now obligated. The
Company does not believe that it is or will be necessary for the Company to
utilize any inventions of any of its employees (or people it currently intends
to hire) made prior to their employment by the Company.

its Certificate of Incorporation or Bylaws, nor is the Company in violation in
any material respect of any mortgage, indenture, contract, agreement,
instrument, judgment or decree, and to the best of the Company's knowledge, the
Company is not in violation of any order, statute, rule or regulation applicable
to the Company. The execution, delivery and performance of and compliance with
this Agreement and the other agreements contemplated hereby, and the issuance
and sale of the Securities pursuant hereto, will not result in (a) any such
violation, or (b) be in conflict with or constitute a default under any such
term, or (c) result in the creation of any mortgage, pledge, lien, encumbrance
or charge upon any of the properties or assets of the Company pursuant to any
such term. In addition, the execution, delivery and performance of and
compliance with this Agreement and the other agreements contemplated hereby, and
the issuance and sale of the Securities pursuant hereto, will not result in a
violation of any law, statute or regulation applicable to the Company.

                  3.8 Employees. Each officer and key employee of the Company
has executed an Employee Proprietary and Confidential Information Agreement, the
form of which has been provided to the Purchasers or their special counsel. The
Company, after reasonable investigation, is not aware that any of its employees
are in violation thereof, and the Company will use its best efforts to prevent
any such violation.

                  3.9 Litigation, etc. Except as set forth on Exhibit B, there
are no actions, proceedings or investigations pending against the Company or its
officers, directors, or shareholders, or to the best of the Company's knowledge,
against employees or consultants of the Company (or, to the best of the
Company's knowledge, any basis therefor or threat thereof): (1) which might
result in (a) any material adverse change in the business, prospects,
conditions, affairs or operations of the Company, or in any of their properties
or assets, or (b) any material impairment of the right or ability of the Company
to carry on its business as now conducted or as proposed to be conducted, or (c)
any material liability on the part of the Company; or (2) which questions the
validity of this Agreement or any action taken or to be taken in connection
herewith. The Company does not currently plan to initiate any litigation.

                  3.10 Governmental Consent, etc. No consent, approval or

valid execution and delivery of this Agreement; or (b) the offer, sale or
issuance of the Securities; or (c) the obtaining of the consents, permits and
waivers specified in subsection 5.1(c) hereof; or (d) the consummation of any

local governmental agencies or instrumentalities. The Company has paid or
established reserves for all income, franchise and other taxes due as reflected

Purchaser will be acquired for investment for the Purchaser's own account, for
investment and not with a view to, or for resale in connection with, any
distribution or public offering thereof within the meaning of the Securities Act
and the Law. The Purchaser has the full right, power and authority to enter into
and perform this Agreement and all other agreements contemplated hereby, and
this Agreement and all other agreements contemplated hereby constitute valid and
binding obligations of the Purchaser. The Purchaser acknowledges and understands

<PAGE>   6




                           (b)      The Purchaser will not sell, negotiate,
pledge or otherwise dispose of any of the Securities (other than in conjunction
with an effective registration statement for the Securities under the Act) in
the United States, its territories and possessions or any area subject to its
jurisdiction, or to any person who is a national or resident of the United
States (including any estate of such person or any corporation, partnership or
other entity created or organized therein) unless and until (i) the Purchaser
shall have notified the Company of the proposed disposition and shall have
furnished the Company with a statement of the circumstances surrounding the
proposed disposition, and (ii) the Purchaser shall have furnished the Company
with an opinion of counsel satisfactory in form and substance to the Company to
the effect that such disposition will not require registration under the
Securities Act.

                           (c)      The Purchaser has such knowledge and 
experience in financial and business matters as to be capable of evaluating the
merits and risks of the Purchaser's prospective investment in the Securities.
The Purchaser has the ability to bear the economic risks of the Purchaser's
prospective investment. The Purchaser has been furnished with and has had access
to such information as the Purchaser has considered necessary to make a
determination as to the purchase of the Securities together with such additional
information as is necessary to verify the accuracy of the information supplied.
The Purchaser has had all questions which have been asked by the Purchaser
satisfactorily answered by the Company. The Purchaser has not been offered the
Securities by any form of advertisement, article, notice or other communication
published in any newspaper, magazine, or similar media or broadcast over
television or radio, or any seminar or meeting whose attendees have been invited
by any such media.

                  4.2 Legends. Each certificate representing the Securities may
be endorsed with the following legends:

                           (a)      THE SECURITIES EVIDENCED BY THIS CERTIFICATE
HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY
NOT BE SOLD, TRANSFERRED, ASSIGNED OR HYPOTHECATED UNLESS THERE IS AN EFFECTIVE
REGISTRATION STATEMENT UNDER SUCH ACT COVERING SUCH SECURITIES, THE SALE IS MADE
IN ACCORDANCE WITH RULE 144 UNDER THE ACT, OR THE COMPANY RECEIVES AN OPINION OF
COUNSEL FOR THE HOLDER OF THESE SECURITIES REASONABLY SATISFACTORY TO THE
COMPANY, STATING THAT SUCH SALE, TRANSFER, ASSIGNMENT OR HYPOTHECATION IS EXEMPT
FROM THE REGISTRATION AND PROSPECTUS DELIVERY REQUIREMENTS OF SUCH ACT.

                           (b)      THE HOLDER WILL NOT SELL, HYPOTHECATE,
PLEDGE, OR OTHERWISE DISPOSE OF ANY INTEREST IN THE SHARES IN THE UNITED STATES,
ITS TERRITORIES AND POSSESSIONS OR ANY AREA SUBJECT TO ITS JURISDICTION, OR TO
ANY PERSON WHO IS A NATIONAL OR RESIDENT OF THE UNITED STATES (INCLUDING ANY
ESTATE OF SUCH



                                        6


<PAGE>   7



PERSON OR ANY CORPORATION, PARTNERSHIP OR OTHER ENTITY CREATED OR ORGANIZED
THEREIN) UNLESS SUCH SHARES HAVE BEEN EITHER REGISTERED UNDER THE SECURITIES ACT
OR ARE EXEMPT, IN THE OPINION OF THE COMPANY'S COUNSEL, FROM THE REGISTRATION
REQUIREMENTS OF THE SECURITIES ACT.

                           (c)      Any other legends required by the Law.

The Company need not register a transfer of legended Securities, and may also
instruct its transfer agent not to register the transfer of the Securities,
unless the conditions specified in each of the foregoing legends are satisfied.

                  4.3 Removal of Legend and Transfer Restrictions. Any legend
endorsed on a certificate pursuant to subsection 4.2(a) and 4.2(b) and the stop
transfer instructions with respect to such legended Securities shall be removed,
and the Company shall issue a certificate without such legend to the holder of
such Securities if such Securities are registered under the Securities Act and a
prospectus meeting the requirements of Section 10 of the Securities Act is
available or if such holder satisfies the requirements of Rule 144(k) and, where
reasonably deemed necessary by the Company, the holder provides the Company with
an opinion of counsel for such holder of the Securities, reasonably satisfactory
to the Company, to the effect that (i) such holder meets the requirements of
Rule 144(k) or (ii) a public sale, transfer or assignment of such Securities may
be made without registration.

                  4.4 Rule 144. The Purchaser is aware of the adoption of Rule
144 by the SEC promulgated under the Securities Act, which permits limited
public resales of securities acquired in a nonpublic offering, subject to the
satisfaction of certain conditions. The Purchaser understands that under Rule
144, the conditions include, among other things: the availability, under certain
conditions, of certain current public information about the issuer and the
resale occurring not less than two years after the party has purchased and paid
for the securities to be sold. The Company covenants that (i) the Company will
use its best efforts to comply with the current public information requirements
of Rule 144(c)(1) under the Securities Act; and (ii) at all such times as Rule
144 is available for use by the Purchaser, the Company will furnish the
Purchaser upon request with all information within the possession of the Company
required for the preparation and filing of Form 144.

                             SCHEDULE OF EXCEPTIONS

                            AUREAL SEMICONDUCTOR INC.

         Pursuant to Section 3 of the Common Stock Purchase Agreement dated June
10, 1996 (the "Agreement"), by and among Aureal Semiconductor Inc., a Delaware
corporation (the "Company"), and the Purchasers set forth on Exhibit A thereto,
Company hereby delivers this Schedule of Exceptions to the Company's
representations and warranties given in the Agreement. The section numbers in
this schedule correspond to the section numbers in the Agreement. Any
information disclosed herein under any section, however, shall be deemed to be
disclosed and incorporated in any other section of the Agreement where such
disclosure would be appropriate. Capitalized terms used in this schedule unless
otherwise specified have the same meanings given them in the Agreement.

         Section 3.3. On May 7, 1996, the Company entered into an Agreement and
Plan of Reorganization (the "Reorganization Agreement") with Aureal Acquisition
Corporation, a California corporation and a wholly-owned subsidiary of the
Company ("Sub") and Crystal River Engineering, Inc., a California corporation
("CRE") pursuant to which Sub was merged with and into CRE (the "Merger"). As
provided by the Reorganization Agreement, the Company paid $8.30 for each
outstanding share of CRE and assumed all of the outstanding options to acquire
CRE securities. The Merger closed on May 29, 1996, at which time the Company
assumed options to acquire, in the aggregate, 2,644,845 shares of the Company's
common stock.

         Section 3.6. As described in its 1995 Form 10-K, on August 23, 1995,
the Company announced it had been named as a defendant in a lawsuit brought by
Creative Technology Ltd. ("Creative"). In its lawsuit, Creative claims the
Company breached a 1992 agreement between the companies settling previous
litigation. The suit seeks any revenues realized by the Company from the sale of
certain products.

         As described in the Company's 1995 Form 10-K, Yamaha has aggressively
brought patent infringement actions against other companies which have developed
certain replacement FM synthesis chips. There can be no assurance that Yamaha
will not pursue the Company under similar theories.

         The Company has sold its Media Vision retail trade names to a third
party.

         The Company is in default of its agreement dated December 23, 1994,
with AT&T, its long distance carrier. The Company is attempting to renegotiate
the terms of its agreement with AT&T. The Company is also in default of the
terms of its Replication and Bundling Agreement with Compton's NewMedia. The
Company



                                       14


<PAGE>   15



believes it has recorded adequate reserves for any potential liability it may
have under the AT&T and Compton's agreements in its 1995 financial statements.

         Section 3.9. See Section 3.6.

         Section 3.13. The Company has entered into a Registration Rights
Agreement dated December 30, 1994 (the "Rights Agreement"), with TCW Special
Credits, as agent and nominee for the entities set forth on Schedule I to such
agreement. The Rights Agreement was amended on February 21, 1996 (the "Amendment
Number 1"), to grant equal registration rights to the purchasers of the
Company's common stock set forth on Exhibit A to the Common Stock Purchase
Agreement dated February 21, 1996 by and among the Company and such purchasers
(the "Purchasers"), and those holders of warrants to purchase shares of the
Company's common stock set forth in Schedule A on the Amendment Number 1.

                          REGISTRATION RIGHTS AGREEMENT

         THIS AMENDMENT NUMBER 2 (the "Amendment") to the Registration Rights
Agreement dated as of December 30, 1994, and Amendment Number 1 dated February
21, 1996 (the "Rights Agreement"), is made as of June 10, 1996, by and among
Aureal Semiconductor Inc., a Delaware corporation (the "Company"), TCW Special
Credits, a California general partnership as agent and nominee for the entities
set forth on Schedule I to the Rights Agreement, Appaloosa Management L.P., as
agent for the accounts listed on Schedule I hereto ("Appaloosa"), the Copernicus
Fund, L.P. ("Copernicus"), the Galileo Fund, L.P. ("Galileo"), and the
purchasers of Common Stock set forth on Exhibit A to the Common Stock Purchase
Agreement dated June 10, 1996 (the "Purchase Agreement"), by and among the
Company and such purchasers (the "Purchasers"). Unless specifically designated
otherwise, the capitalized terms herein shall have the same meanings given them
in the Rights Agreement.

                                    RECITALS

         A. The Company and TCW are parties to the Rights Agreement pursuant to
which the Company granted certain registration rights for the benefit of TCW.

         B. The Company, TCW, Appaloosa, Copernicus, and Galileo (TCW,
Appaloosa, Copernicus, and Galileo are collectively referred to herein as the
"Prior Holders") amended the Rights Agreement pursuant to Amendment Number 1 to
Registration Rights Agreement dated February 21, 1996, to grant equal
registration rights to all the Prior Holders and to make each of the Prior
Holders a party to the Rights Agreement.

         C. The Company and the Prior Holders now wish to amend the Rights
Agreement, as amended, in order to grant equal registration rights to the
Purchasers and to make each of the Purchasers a party to the Rights Agreement,
as amended.

                                    AGREEMENT

         NOW THEREFORE, in consideration of the mutual promises, covenants and
conditions hereinafter set forth, the parties hereto agree to amend certain
provisions of the Rights Agreement as set forth below:

                  1. Section 1 of the Rights Agreement shall be amended to
define the following terms as follows:

         Registrable Shares shall mean (i) all shares of New Common Stock
originally issued to or purchased in the future by TCW, (ii) all shares of
Common Stock issued 

 

                                        1


<PAGE>   2



to the Prior Holders pursuant to the Common Stock Purchase Agreement dated
February 21, 1996, by and among the Company, TCW, Appaloosa, Copernicus, and
Galileo, and (iii) all shares of Common Stock issued to the Purchasers pursuant
to the Purchase Agreement. As to any particular Registrable Shares, such shares
shall cease to be Registrable Shares when (A) such shares shall have been
transferred, new certificates for such shares not bearing a legend restricting
further transfer shall have been delivered by the Company and subsequent
disposition of such shares shall not require registration or qualification under
the Securities Act or any similar state law then in force, or (B) such shares
shall have ceased to be outstanding.

                  2. Section 4(a) of the Rights Agreement shall be amended and
restated in its entirety to provide as follows:

                  (a) On or prior to June 5, 1996, the Company shall prepare and
file with the SEC a Registration Statement for an offering to be made on a
continuous basis pursuant to Rule 415 covering all of the Registrable Shares
(the "Initial Shelf Registration"). The Initial Shelf Registration shall be on a
Form S-3 or another appropriate form permitting registration of such Registrable
Shares for resale by such holders in the manner or manners designated by them
(including, without limitation, one of more underwritten offerings). The Company
shall not permit any securities other than the Registrable Shares to be included
in the Initial Shelf Registration or any Subsequent Shelf Registration. The
Company shall use its best efforts to cause the Initial Shelf Registration to be
declared effective under the Securities Act on or prior to the 60th day
following the date on which the Initial Shelf Registration Statement is filed
and to keep the Initial Shelf Registration continuously effective under the
Securities Act until (i) all Registrable Shares covered by the Initial Shelf
Registration have been sold in the manner set forth and as contemplated in the
Initial Shelf Registration or (ii) a Subsequent Shelf Registration covering all
of the Registrable Shares has been declared effective under the Securities Act
(the "Effectiveness Period"). The Company shall use its best efforts to include
the Registrable Shares purchased by the Purchasers pursuant to the Purchase
Agreement in the Initial Shelf Registration.

                  3. Except as amended hereby, the Rights Agreement dated
November 30, 1994, as amended on February 21, 1996, remains in full force and
effect.

                  4. By their signatures hereto, each of the Purchasers becomes
a party to the Rights Agreement, as amended by this Amendment Number 2.
