     THIS COMMON STOCK PURCHASE AGREEMENT is made as of June 10, 1996, by and 
among AUREAL SEMICONDUCTOR INC., a Delaware corporation (the "Company"), and 
the purchasers set forth on the Schedule of Purchasers attached hereto as

     WHEREAS, the Company desires to issue and sell to the Purchasers and the 
Purchasers desire to purchase shares of the Common Stock of the Company.

     NOW, THEREFORE, in consideration of the mutual promises, covenants and 
conditions hereinafter set forth, the parties hereby agree as follows:

     1.   SALE OF THE SECURITIES.

          1.1  SALE.  Subject to the terms and conditions hereof, the Company 
will issue and sell to the Purchasers and the Purchasers will purchase up to

     2.   CLOSING DATES; DELIVERY.

          2.1  CLOSING DATE.  The closing of the purchase and sale of the
Securities (the "Closing") shall be held at the offices of Gray Cary Ware &

          2.2  DELIVERY.  Subject to the terms of this Agreement, at the

<PAGE>

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 be so qualified, licensed or domesticated would result in material adverse 
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 other agreements contemplated hereby are valid and binding 
obligations of the Company, except as the same may be limited by bankruptcy, 
insolvency, fraudulent 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 
outstanding shares and all options and warrants to purchase Common Stock), 
for issuance under the Plans (as such term is defined below).  As of May 31, 
1996, 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 Option Plan (collectively, the "Plans") for future 
issuance to key employees, 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

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.

<PAGE>

          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.

          3.7  COMPLIANCE WITH OTHER INSTRUMENTS, NONE BURDENSOME, ETC.  
Except as set forth in EXHIBIT B, the Company is not in violation of any term 
of 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 



                                    3

<PAGE>

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 
authorization of or designation, declaration or filing with any governmental 
authority on the part of the Company is required in connection with: (a) the 
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 
other transaction contemplated hereby; except, if required, filings or 
qualifications under the Securities Act of 1933, as amended (the "Securities 
Act") and California Corporate Securities Law of 1968, as amended (the 
"Law"), which filings or qualifications, if required, will have been timely 
filed or obtained.

          3.11 OFFERING.  In reliance on the representations and warranties 
of the Purchasers in Section 4 hereof, the offer, sale and issuance of the 
Securities in conformity with the terms of this Agreement will not result in 
a violation of the requirements of Section 5 of the Securities Act or the 
qualification requirements of the Law.

          3.12 TAXES.  The Company has timely filed all tax returns that are
required to have been filed with appropriate federal, state, county and local

<PAGE>

governmental agencies or instrumentalities.  The Company has paid or 
established reserves for all income, franchise and other taxes due as 
reflected on said returns.  There is no pending dispute with any taxing 
authority relating to any of such returns and the Company has no knowledge of 
any proposed liability for any tax to be imposed upon the properties or 
assets of the Company for which there is not an adequate reserve reflected in 
the Financial Statements (as defined below).

          3.13 REGISTRATION RIGHTS.  Other than as set forth on EXHIBIT B, the
Company is not obligated to register any of its presently outstanding securities
or any of its securities which may hereafter be issued.

          3.14 DISCLOSURE.  Neither this Agreement and the exhibits hereto, 
nor any of the other statements or certificates furnished or to be furnished 
to the Purchasers pursuant hereto or in connection with the transactions 
contemplated hereby, including the Company's Annual Report on Form 10-K for 
the fiscal year ended December 31, 1995, and any amendments to date thereto, 
the Company's Proxy Statement for the 1996 Annual Meeting of Stockholders, 
and the Company's first quarter 1996 Report on Form 10-Q, contains any untrue 
statement of a material fact or omits to state any material fact necessary in 
order to make the statements contained herein and therein not misleading in 
light of the circumstances under which such statements were made.

     4.   REPRESENTATIONS, WARRANTIES AND COVENANTS OF THE PURCHASERS AND
RESTRICTIONS ON TRANSFER IMPOSED BY THE SECURITIES ACT OF 1933.

          4.1  REPRESENTATIONS,  WARRANTIES AND COVENANTS BY THE PURCHASERS. 
Each Purchaser represents, warrants and covenants to the Company as follows:

               (a)  The Securities to be received by the 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 that the Securities must be held indefinitely unless the 
Securities are subsequently registered under the Securities Act and qualified 
under the Law or an exemption from such registration and such qualification 
is available.

               (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 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.

                              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 believes it has

- - ---------------------------------------------  )    AND TOYOTA-TSUSHO CLAIM



      Media Vision Technology Inc. ("Debtor"), the Official Unsecured 
Creditors' Committee (the "Committee") and TCW Special Credits, as Agent and 
Nominee for the entities listed on Exhibit A ("TCW"), through their 
respective counsel of record, stipulate as follows with respect to the 
bankruptcy case of the Debtor:

     1. Pursuant to a transfer of claim, TCW is the holder of the secured 
Letter of Credit Claim ("Letter of Credit Claim") as defined in Debtor's 
Second Amended Joint Plan of 



<PAGE>

Reorganization ("Plan"). The Letter of Credit Claim is comprised of the 
Debtor's obligations to reimburse the holder of the Letter of Credit Claim 
for any payment the holder of such claim may make under letters of credit 
issued by Comerica in favor of Toyota-Tsusho Corporation ("Toyota-Tsusho") 
for the account of the Debtor under a pre-petition credit agreement. The Plan 
provided that the Letter of Credit Claim may not exceed the amount of 
$2,300,000, and sufficient shares were reserved in the Class 2 and Class 6 
Reserves (as defined in the Plan) to satisfy the Letter of Credit Claim. 
However, because the Fee Claim of TCW (as defined in the Plan) was allowed in 
an amount less than the amount for which shares were reserved for the Fee 
Claim, an additional 33,137 shares were reserved for the Letter of Credit Claim.

     2.  Pursuant to the terms of the Plan, the Letter of Credit Claim is 
contingent, and will not be allowed until such claim becomes noncontingent. A 
judgment was entered in state court litigation regarding the letter of credit 
in favor of Toyota-Tsusho in the full amount of the claim plus interest, 
which Toyota-Tsusho calculated to be in excess of $2,650,000 as of October 
1996. Comerica and TCW satisfied the judgment in accordance with a settlement 
agreement with Toyota-Tsusho.

     3.  Toyota-Tsusho filed Proof of Claim No. 694, an unsecured claim in 
the amount of $1,995,756.00 ("Claim No. 694"). Claim No. 694 arises in 
connection with amounts owed to Toyota-Tsusho from Debtor relating to the 
Letter of Credit Claim. Claim No. 694 was transferred to TCW.


                                     -2- 
<PAGE>

     4.  The Debtor and the Committee believe that they can have certain 
objections to the Letter of Credit Claim and Claim No. 694, and, therefore, 
filed an objection to Claim No. 694 ("Objection").  The Letter of Credit 
Claim could not be allowed so long as such claim was contingent.  In the 
interest of resolving their differences with TCW, both Debtor and the 
Committee are willing to stipulate that the Letter of Credit Claim should be 
allowed in a certain specified amount, Claim No. 694 shall be disallowed in 
its entirety, and the Objection withdrawn, and TCW is willing to release any 
claim to the 33,137 additional shares reserved for the Letter of Credit Claim.

     5.  Debtor, the Committee and TCW hereby stipulate as follows: a) The 
Letter of Credit Claim is allowed as a secured claim under the Plan in the 
total amount of $2,300,000.00, and shall receive New Common Stock, as defined 
in the Plan, based on a price of $4.00 per share for a total of 575,000 
shares of New Common Stock from the Class 2 and Class 6 Reserves, as defined 
in the Plan; (b) Claim No. 694 shall be disallowed in its entirety; c) The 
Objection shall be withdrawn; d) TCW hereby releases all claims to the 33,137 
shares reserved for the Letter of Credit Claim; and e) Except as set forth 
herein, TCW shall not be entitled to any shares of New Common Stock on 
account of the Letter of Credit Claim or Claim No. 694.  All parties shall 
bear their own costs.

     6.  Pursuant to paragraph 28 of the Order Confirming Debtor's Second 
Amended Joint Plan of Reorganization, objections to claim must be filed by 
January 18, 1995, or such later date as the Court may order.  Such date has 
passed, and no objections

                                       -3-

<PAGE>

have been filed to the claim by any third parties. Hence, it is appropriate 
the Debtor, the Committee and TCW are able to effectively stipulate to the 
allowed amount of the Letter of Credit Claim and Claim No. 694.

     7.  Pursuant to the Bankruptcy Court's Order Granting Application of 
Debtor and Committee for Authority to Compromise and Settle Controversies 
Regarding Objections to Certain Claims entered on March 20, 1995, this 
Stipulation will be deemed effective upon its execution by the parties and 
filing with the Court, without further hearing, notice, approval or order by 
the Court.

     THIS AMENDMENT NUMBER 2 (the "Amendment") to the Registration Rights
Agreement dated as of December 30, 1994, and Amendment Number 1 dated Febraury
21, 1996 (the "Rights Agreement"), is made as of June 10, 1996, by and among

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

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 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 


                                        1

<PAGE>


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.

provisions of this Agreement or the Warrants, as the case may be, will be 
validly issued, fully paid and nonassessable, and will be free of any liens 
or encumbrances; provided, however, that the Shares, Warrants and Warrant 
Shares 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

no known 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

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.

          3.6  COMPLIANCE WITH OTHER INSTRUMENTS, NONE BURDENSOME, ETC.  
Except as set forth in EXHIBIT C, the Company is not in violation of any term 
of 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 Shares, Warrants and 
Warrant Shares 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 Units and Warrants pursuant hereto, will not result 
in a violation of any law, statute or regulation applicable to the Company.

          3.7  EMPLOYEES.  Each officer and key employee of the Company has 
executed an Employee Proprietary and Confidential Information Agreement.  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.

          3.8  LITIGATION, ETC.  Except as set forth on EXHIBIT C, there are 
no actions, proceedings or investigations pending against the Company or its 
officers, directors, or stockholders, 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

taken in connection herewith.  The Company does not currently plan to 
initiate any litigation.

          3.10 OFFERING.  In reliance on the representations and warranties 
of the Purchasers in Section 4 hereof, the offer, sale and issuance of the

violation of the requirements of Section 5 of the Securities Act or the 
qualification requirements of the Law.

          3.11 TAXES.  The Company has timely filed all tax returns that are 
required to have been filed with appropriate federal, state, county and local

established reserves for all income, franchise and other taxes due as 
reflected on said returns.  There is no pending dispute with any taxing 
authority relating to any of such returns and the Company has no knowledge of 
any proposed liability for any tax to be imposed upon the properties or 
assets of the Company for which there is not an adequate reserve reflected in 
the Company's financial statements contained in the 10-Q or the Company's 
Annual Report on Form 10-K for the fiscal year ended December 29, 1996 (the 
"10-K").

Each Purchaser represents, warrants and covenants to the Company as follows:




                                           5

<PAGE>

               (a)  The Units to be received by the 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 that the Units must be held indefinitely unless the Units are 
subsequently registered under the Securities Act (see Section 6.2) and 
qualified under the Law or an exemption from such registration and such 
qualification is available.

               (b)  The Purchaser will not sell, negotiate, pledge or 
otherwise dispose of any of the Units (other than in conjunction with an 
effective registration statement for the Units under the Securities 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 
(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 Units.  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 Units together with such additional information as 
is necessary to verify the accuracy of the information supplied.  The 
Purchaser is fully aware of (i) the highly speculative nature of the 
investment in the Units; (ii) the financial hazards involved; (iii) the lack 
of liquidity of the Shares, Warrants and Warrant Shares, and the restrictions 
on the transferability of the Shares, Warrants and Warrant Shares; and (iv) 
the tax consequences of investment in the Units.  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 Units 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 or other instruments representing 
any of the Shares and Warrant Shares 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 




                                          6

<PAGE>

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 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 Shares, Warrants or Warrant
Shares, and may also instruct its transfer agent not to register the transfer of
the Shares, Warrants or Warrant Shares 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 or other instrument 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 Securities and Exchange Commission (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.

     Pursuant to Section 3 of the Unit Purchase Agreement dated August 6, 
1997 (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 July 25, 1994, the company and its then wholly-owned 
subsidiary, Pellucid, Inc. ("Pellucid") filed separate voluntary petitions in 
the United States Bankruptcy Court seeking protection under Chapter 11 of the 
United States Bankruptcy Code.  On December 19, 1994, the Bankruptcy Court 
confirmed the companies' Second Amended Joint Plan of Reorganization (the 
"Plan of Reorganization") which became effective December 30, 1994.  Pursuant 
to the Plan of Reorganization, certain shares of Common Stock were held in 
escrow for the final satisfaction of claims pending against the Company.  
There are currently approximately 48,000 shares of Common Stock held in 
escrow.  Pursuant to voting agreements between the Company and the escrow 
holders, the escrow holders have agreed to vote all such shares in each 
election of directors and with respect to other matters submitted to a 
stockholder vote in the same proportions as the votes cast by the outstanding 
shares of Common Stock not held in escrow.

     The Company may increase the reserves under the Plans and the Outside 
Director Stock Option Plan so that the reserves under such plans, in the 
aggregate, equal twenty percent (20%) of the then fully diluted Common Stock 
of the Company.

     SECTION 3.5.  As described in the Company's 1996 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. 

     SECTION 3.8.  See Section 3.5.

     THIS AMENDMENT NUMBER 3 (the "Amendment") to the Registration Rights 
Agreement dated as of December 30, 1994, as amended by Amendment Number 1 
dated February 21, 1996 and Amendment Number 2 dated June 10, 1996 (the 
"Rights Agreement"), is made as of August 6, 1997, by and among Aureal 
Semiconductor Inc., a Delaware corporation (the "Company"), the purchasers of 
Units set forth on Exhibit A to the Unit Purchase Agreement dated August 6, 
1997 (the "Purchase Agreement"), by and among the Company and such purchasers 
(the "Purchasers"), and the Prior Holders (as defined below).  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 (collectively, 
the "No. 1 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 No. 1 Prior Holders and to make each of 
the No. 1 Prior Holders a party to the Rights Agreement.

     C.   The Company, the No. 1 Prior Holders and the purchasers set forth 
on Exhibit A to the Common Stock Purchase Agreement dated June 10, 1996, 
amended the Rights Agreement pursuant to Amendment Number 2 to Registration 
Rights Agreement dated June 10, 1996 (such purchasers and the No. 1 Prior 
Holders are collectively referred to herein as the "No. 2 Prior Holders") to 
grant equal registration rights to the No. 2 Prior Holders and to make each 
of the No. 2 Prior Holders a party to the Rights Agreement.

     D.   The No. 1 Prior Holders and the No. 2 Prior Holders are 
collectively referred to herein as the Prior Holders and are set forth on 
SCHEDULE 1 hereto. 

     E.   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 



                                          1

<PAGE>


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 to the Prior Holders pursuant to the Common Stock 
Purchase Agreements dated February 21, 1996, and June 10, 1996, by and among 
the Company and such Prior Holders, (iii) all shares of Common Stock issued 
pursuant to the Purchase Agreement to the Purchasers, (iv) all Warrant Shares 
issued upon exercise of the Warrants (as defined in the Purchase Agreement) 
and (v) shares of Common Stock issuable upon exercise of warrants issued 
pursuant to the Second Amended and Restated Loan Agreement dated August 6, 
1997 (the "Loan Agreement") between the Company and TCW (including 470,455 
shares of Common Stock issuable upon exercise of warrants issued to B III 
Capital Partners as a participant under the Loan 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, as amended, shall be 
amended and restated in its entirety to provide as follows:

               (a)  The Company has registered the Registrable Shares, other 
than those described in Sections 1(iii), (iv) and (v) and certain of those 
described in Section 1(i) herein (collectively, the "UNREGISTERED REGISTRABLE 
SHARES"), on Form S-3 (No. 333-3870) (the "INITIAL SHELF REGISTRATION").  The 
Company will use its best efforts to include the Unregistered Registrable 
Shares in the Initial Shelf Registration.  If not included in the Initial 
Shelf Registration  within ninety (90) days after the Closing under the 
Purchase Agreement, the Company will file a Subsequent Shelf Registration 
within ninety (90) days after the Closing under the Purchase Agreement and 
will use its best efforts to have such Subsequent Shelf Registration declared 
effective by the SEC.  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 
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 and the Registrable Shares covered thereby have been sold in 
the manner set forth and as contemplated in such Subsequent Shelf 
Registration (the "EFFECTIVENESS PERIOD").   

          3.   Except as amended hereby, the Rights Agreement dated November 
30, 1994, as amended on February 21, 1996, and on June 10, 1996, remains in 
full force and effect.

          4.   By their signatures hereto, each of the Purchasers becomes a
party to the 


                                       2

Rights Agreement.

     IN WITNESS WHEREOF, the parties have executed this Amendment Number 3 as of
the day and year first above written.

     F.   The Company and the Prior Holders now wish to amend the Rights 
Agreement, as amended, in order to grant equal registration rights to the 
Series B Holders and to make each of the Series B Holders 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 to the Prior Holders pursuant to the Common Stock 
Purchase Agreements dated February 21, 1996, March 11, 1996 and June 10, 
1996, by and among the Company and such Prior Holders, (iii) all shares of 
Common Stock issued pursuant to the Unit Purchase Agreement dated August 6, 
1997 by and among the Company and such Prior Holders (the "Unit Purchase 
Agreement"), (iv) all Warrant Shares issued upon exercise of the Warrants (as 
defined in the Unit Purchase Agreement), (v) shares of Common Stock issuable 
upon exercise of warrants issued pursuant to the Second Amended and Restated 
Loan Agreement dated August 6, 1997 (the "Loan Agreement") between the 
Company and TCW (including 450,000 shares of Common Stock issuable upon 
exercise of warrants issued to B III Capital Partners as a participant under 
the Loan Agreement) and (vi) shares of Common Stock issuable upon conversion 
of the shares of the Company's Series B Preferred Stock issued to the Series 
B Holders pursuant to the Series B Agreement and Certificate of Designation 
for the Company's Series B Preferred Stock.  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, as amended, shall be
amended and restated in its entirety to provide as follows:

               (a)  The Company has registered the Registrable Shares, other 
than those described in Section 1(vi) and certain of those described in 
Section 1(i) herein (collectively, the "UNREGISTERED REGISTRABLE SHARES"), on 
Form S-3 (No. 333-3870) (the "INITIAL SHELF REGISTRATION").  The Company will 
use its best efforts to include the Unregistered Registrable Shares in the 
Initial Shelf Registration.  If not included in the Initial Shelf 
Registration  within ninety (90) days after the Closing under the Series B 
Agreement, the Company will file a Subsequent Shelf Registration within 
ninety (90) days after the Closing under the Series B Agreement and will use 
its best efforts to have such Subsequent Shelf 


                                      2

<PAGE>

Registration declared effective by the SEC.  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 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 and the Registrable Shares covered thereby 
have been sold in the manner set forth and as contemplated in such Subsequent 
Shelf Registration (the "EFFECTIVENESS PERIOD").   

          3.   Except as amended hereby, the Rights Agreement dated 
December 30, 1994, as amended on February 21, 1996, on June 10, 1996 and on
August 6, 1997, remains in full force and effect.

          4.   By its signature hereto, each of the Series B Holder becomes a 
party to the Rights Agreement.

     IN WITNESS WHEREOF, the parties have executed this Amendment Number 4 to 
the Registration Rights Agreement as of the day and year first above written.

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

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

any order, statute, rule or regulation applicable to the Company, including 
by not limited to the Securities Exchange Act of 1934 and the reporting 
obligations of the issuer with respect to Rule 144 under the Securities Act.  
The execution, delivery and performance of and compliance with this Agreement 
and the other agreements contemplated hereby, and the issuance and sale of 
the Series B Stock (and the issuance of the Common Stock issuable upon 
conversion of the Series B Stock) 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 Series B Stock pursuant 


                                       4

applicable to the Company, including Section 203 of the Delaware General 
Corporation Law.

no actions, proceedings or investigations pending against the Company or its 
officers, directors, or stockholders, 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.

          3.9  GOVERNMENTAL CONSENT, ETC.  No consent, approval or 
authorization of or designation, declaration or filing with any governmental 
authority or any other person on the part of the Company is required in

RESTRICTIONS ON TRANSFER IMPOSED BY THE SECURITIES ACT OF 1933.

          4.1  REPRESENTATIONS,  WARRANTIES AND COVENANTS BY THE PURCHASERS. 
Each Purchaser represents, warrants and covenants to the Company as follows:

               (a)  The Series B Stock and the Common Stock issuable upon 
conversion of the Series B Stock (collectively, for purposes of this Section 
4, the "Securities") to be received by the 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 that the Securities must be held indefinitely unless the 
Securities are subsequently registered under the Securities Act and qualified 
under the Law or an exemption from such registration and such qualification 
is available.

               (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 Securities Act 
or an exemption from registration under applicable federal securities laws).

               (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


                                       6

<PAGE>


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 is fully 
aware of (i) the highly speculative nature of the investment in the 
Securities; (ii) the financial hazards involved; (iii) the lack of liquidity 
of the Securities, and the restrictions on the transferability of the 
Securities; and (iv) the tax consequences of investment in the Securities.  
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 Series B Stock 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 or other instruments representing 
any of 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)  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 or other instrument 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 Securities and Exchange Commission (the "SEC") promulgated under the 
Securities Act,


                                       7

<PAGE>


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 one year 
(with certain restrictions) 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.

As described in the Company's 1996 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.

On February 27, 1998, Aureal was served with an action filed by Creative 
Technology Ltd., a Singapore corporation, and E-MU Systems, Inc., a 
California corporation, in federal district court in the Northern District of 
California, alleging patent infringement by Aureal. The plaintiffs claim that 
Aureal's Vortex 8820 PCI-based AC'97 Digital Audio Processor infringes United 
States Patent No. 5,342,990 entitled "Digital Sampling Instrument Employing 
Cache-Memory" which basically describes a specific implementation for a 
stand-alone music synthesizer circuit. The Company has reviewed the 
allegations in the omplaint and believes that the action is completely 
without merit and intends to vigorously pursue defense of this action.
                                          
Shiva Holdings Limited ("Shiva") filed a cross-complaint against the Company 
in December 1997 alleging breach of contract, breach of implied covenant of 
good faith and fair dealing, fraud and negligent misrepresentation in 
connection with the Agreement for Purchase of

Certain Assets entered into between Shiva and the Company in February 1996.  
The Company had filed an action against Shiva for breach of contract and 
specific performance in connection with the failure of Shiva to pay 
certain amounts due under the February 1996 agreement. Shiva alleges that 
the Company made certain misrepresentations in the sale of assets by the 
Company to Shiva and is seeking damages in excess of $1,000,000.  The
Company believes that the claims by Shiva are groundless and intends to 
defend them vigorously.

On or about September 4, 1997, Jonathan S. Abel, Ph.D., filed a Demand for 
Arbitration against the Company in the San Francisco office of the American 
Arbitration Association.  The demand asserts claims for declaratory relief 
and breach of contract.  It seeks general and compensatory damages of 
$16,770, together with additional damages according to proof, and a judicial 
determination that Dr. Abel has performed his contractual duties, has not 
misappropriated any Aureal trade secrets and that certain technology that Dr. 
Abel has developed does not belong to Aureal.  The Company believes that the 
claims by Dr. Abel are groundless and intends to defend them vigorously.

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