ITEM 2.  ACQUISITION OR DISPOSITION OF ASSETS

         Aureal Semiconductor Inc. (the "Company"), Aureal Acquisition
Corporation, a California corporation and a wholly-owned subsidiary of the
Company ("Sub"), and Crystal River Engineering, Inc., a California corporation
("CRE"), have entered into an Agreement and Plan of Reorganization (the
"Reorganization Agreement"), dated as of May 7, 1996, whereby Sub will be merged
with and into CRE and CRE will become a wholly-owned subsidiary of the Company
(the "Acquisition"). Subject to the terms and conditions of the Reorganization
Agreement (including, without limitation, the consent of the shareholders of
CRE), upon the effective time of the Acquisition, each outstanding share of
Common Stock of CRE will be acquired by the Company at a price per share of
$8.30, and each outstanding and unexercised option for CRE Common Stock will be
assumed by the Company and converted into a option to purchase that number of
shares of the Common Stock of the Company ("Option Shares") determined by
multiplying the number of shares of CRE Common Stock purchasable under such
option by $8.30, with an exercise price per share of the Company's Common Stock
equal to the aggregate exercise price of the assumed CRE option by the Option
Shares. The Closing Date is anticipated to be on or about May 25, 1996. A copy
of the Reorganization Agreement is attached as Exhibit 1 and is incorporated
herein by reference.

         The per share price paid by the Company for CRE's Common Stock
represents the fair market value of such stock, as determined by arms-length
negotiations between the Company and CRE. The Company intends to use some of the
proceeds from its sale of 10,000,000 shares of Common Stock to certain investors
in February and March, 1996, to fund the Acquisition.

         In connection with the Acquisition, the Company will acquire the rights
to 3D audio software which CRE has developed. Prior to the Acquisition, the
Company had contracted with CRE to develop certain audio software.

         A copy of the press release announcing the execution of the
Reorganization Agreement is attached as Exhibit 2 and is incorporated herein by
reference.

         The Company will file the required financial statements and pro forma
financial information as an amendment to this Form 8-K as soon as practicable
but not later than sixty (60) days from the date of this Form.

conditions of this Agreement so that:

shall cease and CRE shall continue as the surviving corporation (sometimes
referred to herein as the "Surviving Corporation"), which shall succeed to and
assume all of the rights and obligations of Sub in accordance with the laws of
California.

                           (b) The Articles of Incorporation and Bylaws of CRE

incorporation and bylaws, respectively, of the Surviving Corporation after the
Effective Time unless and until further amended as provided by law.

                           (c) The directors and officers of Sub immediately
prior to the Effective Time shall be the directors and officers of the Surviving
Corporation after the Effective Time. Such directors and officers shall hold
their position until the election and qualification of their respective
successors or until their tenure is otherwise terminated in accordance with the

                           (b) At the Effective Time, each CRE Common Share
shall, by virtue of the Merger, and without further action on the part of any
holder thereof, be converted into the right to receive the CRE Common Share
Price in accordance with Sections .2.2 ("Cancellation of Shares; Delivery of
Consideration and Assumption of Options") and .2.3 ("Exchange Procedures");
provided, however, that the right to receive certain portions of such amounts or
to receive such amounts with respect to certain CRE Common Shares shall be

<PAGE>   11
Table of Contents, continued



                           (c) At the Effective Time, each share of capital
stock of Sub outstanding immediately prior to the Merger shall, by virtue of the
Merger, and without further action on the part of any holder thereof, continue
to be issued and shall be converted into one share of CRE common stock
outstanding after the Merger.

                           (d) At the discretion of CRE upon notice thereof to
Aureal on or before the Closing Date, the vesting of that portion of any Option
which would have vested after the Closing Date, but on or before September 30,
1996, shall be accelerated so that such vesting shall occur and be effective on
the Closing Date.

         2.3 EXCHANGE PROCEDURES .

                           (a) At the Effective Time, each holder of a
certificate or certificates (each a "Certificate" and collectively, the
"Certificates") representing shares of CRE capital stock issued and outstanding
immediately prior to the Effective Time shall surrender such certificate(s) to
an officer of CRE designated for such purpose. Each Certificate which
immediately before the Effective Time evidenced CRE capital stock shall, from
and after the Effective Time until such certificate is surrendered to CRE or its
transfer agent, be deemed, for all corporate purposes, to evidence the right to
receive the consideration described above; provided, however, that no dividend
or other distribution payable to the holder of such certificate after the
Effective Time shall be paid in respect of such certificate until such
certificate is so surrendered by such holder.

                           (b) At the Effective Time, Aureal shall make
available to each CRE shareholder such consideration as is set forth on Exhibit
A (the "Merger Consideration Schedule") and to each holder of a CRE Option who
has notified CRE in writing of his intent to exercise his Exercised Vested CRE
Option within fourteen (14) days of the date of this Agreement an amount equal
to the CRE Common Share Price multiplied by the number of CRE Shares for which
the Exercised Vested CRE Option was exercised, less the amount required to
exercise the Exercised Vested CRE Option (the amount required to exercise the
Exercised Vested CRE Option shall be paid by Aureal to CRE on the Closing Date);
provided, however, that the amount made available by Aureal to all CRE
shareholders and holders of Exercised Vested CRE Options shall not exceed the
Cash Consideration.

                           (c) Each Exercised Vested CRE Option that is
outstanding immediately prior to the Effective Time shall, by virtue of the
Merger and at the Effective Time, automatically and without further action on
the part of any holder thereof, be exercised by the CRE option holder for CRE
common stock and thereafter converted into the right to receive the CRE Common
Share Price in accordance with Sections .2.2 ("Cancellation of Shares; Delivery
of Consideration and Assumption of Options") and .2.3 ("Exchange Procedures");
provided, however, that such amount made available by Aureal to all CRE
shareholders and holders of 




                                       6
<PAGE>   12
Table of Contents, continued



Exercised Vested CRE Options shall not exceed the
Cash Consideration. In order to exercise a Vested CRE Option, a CRE option
holder shall notify CRE in writing within fourteen (14) days of the date of this
Agreement, including with such notice a form W-9, of his desire to exercise all
or any portion of such Vested CRE Option. Each person who has notified CRE in
writing within fourteen (14) days of the date of this Agreement of his intent to
exercise a Vested CRE Option shall be deemed a shareholder of CRE on the date of
such exercise, as to the number of shares exercised by such person, for all
purposes of this Agreement, including, without limitation, the indemnification
provisions of Section 12 ("Indemnification and Escrow").

                           (d) Each holder of an Unvested CRE Option or a Vested
CRE Option that is outstanding at the Effective Time shall, by virtue of the
Merger and at the Effective Time, have such Unvested CRE Option or Vested CRE
Option be assumed by Aureal and converted into an option (an "Aureal Option") to
purchase that number of shares of Aureal common stock (the "Aureal Option
Shares") determined by multiplying the number of shares of CRE common stock
purchasable under the Unvested CRE Option and Vested CRE Option immediately
prior to the Effective Time by the CRE Common Share Price, with an exercise
price per share of Aureal common stock purchasable under each such Aureal Option
equal to the aggregate exercise price by grant of the Unvested CRE Option and
Vested CRE Option divided by the Aureal Option Shares. After the Effective Time,
Aureal shall issue to those holders of an outstanding Unvested CRE Option or
Vested CRE Option a document evidencing the assumption by Aureal referenced
above. No fractional shares of Aureal common stock shall be issued in connection
with an Aureal Option. All fractional shares which would otherwise be issuable
shall be provided for in accordance with Section .2.4 hereof ("Fractional
Shares"). All of the other terms of each Unvested CRE Option and Vested CRE
Option assumed by Aureal including, without limitation, the vesting period, will
remain the same.

                           (e) Notwithstanding anything to the contrary in this
Section .2.3 ("Exchange Procedures"), no party hereto shall be liable to a
holder of shares of CRE capital stock for any amount properly paid to a public
official pursuant to any applicable abandoned property, escheat or similar law.

                           (f) In the event any Certificates evidencing CRE
capital stock shall have been lost, stolen or destroyed, Aureal shall issue in
exchange for such lost, stolen or destroyed certificates, the cash amount
otherwise issuable under Section .2.2 ("Cancellation of Shares; Delivery of
Consideration and Assumption of Options") upon the making of an affidavit of
that fact by the holder thereof, provided, however, Aureal may, in its
discretion and as a condition precedent to the issue thereof, require the owner
of such lost, stolen or destroyed Certificates to indemnify Aureal against any
claim that may be made against Aureal with respect to the Certificate alleged to
have been lost, stolen or destroyed.

                  2.4 FRACTIONAL SHARES . No fractional shares of Aureal common
stock will be issued in connection with the Merger, but in lieu thereof, a
holder of an Unvested CRE Option or 




                                       7
<PAGE>   13
Table of Contents, continued


Vested CRE Option who would otherwise be entitled to receive a fraction of a
share of Aureal common stock will receive from Aureal, promptly upon the
exercise of such option, an amount of cash equal to the CRE Common Share Price
multiplied by the fraction of a share of Aureal common stock to which such
holder would otherwise be entitled.

                  2.5 APPRAISAL RIGHTS . Any Dissenting Shares shall not receive

license will become effective only if Aureal materially breaches the
representations set forth in Section 4 ("Representations and Warranties of
Aureal and Sub"), breaches the covenants set forth in Sections 6 ("Preclosing
and Postclosing Covenants of Aureal and Sub") or 7 ("Mutual Covenants"), becomes

performance bonus or other additional compensation plan provided by Aureal for
the purpose of incentivising or rewarding employee performance.

                           (b) CRE employees who continue with CRE or Aureal
after the Closing Date shall also be entitled to the same benefits as are now
provided, or, from time to time, will be provided, generally to the employees of
Aureal, it being the intent of the Aureal that all employees of Aureal and CRE

Options issued under this Agreement in exchange for the Vested CRE Options and
Unvested CRE Options) as soon as practicable after the Effective Date.

                  6.6 FORM S-8 . Within thirty (30) days after the Closing,

approved a bonus plan (the "Bonus Plan") on the terms provided in this Section
6.8. The Bonus Plan shall consist of Five Hundred Three Thousand Dollars
($503,000) (the "Bonus Fund"). On or before the Closing, Aureal shall deposit
Two Hundred Forty Thousand Dollars ($240,000) of the Bonus Fund into an escrow
account at a financial institution reasonably acceptable to CRE and Aureal,
pursuant to escrow instructions to be agreed upon by CRE and Aureal prior to the

shall be paid to Aureal from time to time. The Bonus Fund shall be distributed
in three (3) equal payments, the 



                                       30
<PAGE>   36
Table of Contents, continued


three payments to be made to be made on the sixth, twelfth and eighteenth month
anniversaries of the Closing, respectively. The Bonus Plan shall be administered
by the CRE Shareholder Representative to employees who continue to serve as
employees of CRE or Aureal after the Closing; provided, however, that any such
designated employee who is terminated without good cause, as such term is
defined in the Employment Agreement (with respect to any Key Employee) or in the
employment policies of Aureal (with respect to any other designated employee)
may continue to receive an allocated portion of the Bonus Plan payments. The
allocation of the Bonus Funds shall be as set forth in Exhibit C. If a
designated employee is terminated for good cause or resigns from his position,
such designated employee's allocated portion of the Bonus Fund will be returned
to Aureal. The amounts in the Bonus Fund shall be used to satisfy any claims of
Aureal for indemnification, as provided in Section 12 of this Agreement. In the
event that Aureal has any claim for indemnification, Aureal shall notify the CRE
Shareholder Representative of the amount of such claim and such amount shall
thereupon be held in the Bonus Fund and not distributed until such claim has
been established by the agreement of Aureal and the CRE Shareholder
Representative or, in the absence of such agreement, by judicial determination.
At such time as an agreement or judicial determination is reached, then the
amount of the claim, together with any interest earned thereon, shall be paid
from the Bonus Fund to Aureal; if the claim is not valid, then such amount,
together with any interest earned thereon, shall be distributed to the employees
in accordance with the allocations set forth on Exhibit C. In the event that CRE
does not have sufficient cash on hand at the Closing to pay all or any portion
of the Merger Bonus, Aureal shall be obligated to fund the Merger Bonus at the
Closing, and such failure by CRE shall not constitute a breach of this
Agreement.

                  6.9 AUDIT . Aureal acknowledges that its accountants have
begun to conduct the Aureal Audit and shall use its best efforts to assure that
its accountants shall promptly conduct such review and investigation of the
books and records of CRE as may be necessary to establish whether CRE's
financial statements can be integrated into Aureal's financials so as to be in
compliance with the rules and regulations of the Commission.

                  6.10 RESERVATION, REGISTRATION AND ISSUANCE OF AUREAL COMMON
STOCK . Aureal shall reserve and make available for issuance in connection with
the Merger and in accordance with the terms of this Agreement the maximum number
of shares of common stock of Aureal to which the holders of Unvested CRE Options
and Vested CRE Options may be entitled upon exercise of such options. All such
shares will, when issued and delivered pursuant to and in accordance with the
terms of this Agreement be duly authorized, legally and validly issued, fully
paid and nonassessable. Aureal shall file and use its best efforts to cause to
be declared effective pursuant to the Securities Act one or more registration
statements covering all such shares and shall cause all such shares to be issued
in compliance with the Securities Act and in compliance with all applicable
state securities laws and regulations.

obligation to keep it confidential, which knowledge the Receiving Party shall

has the legal right to terminate or suspend any such pending negotiations and
agrees to indemnify Aureal, its representatives and agents from and against any
claims by any party to such negotiations based upon or arising out of the
discussion or any consummation of the Merger.

party cooperate with the other in the development and distribution of all news
releases and other public information disclosures with respect to the Merger and
this Agreement; provided that Aureal may, without the consent of CRE, make any
disclosure with regard to the Merger or this Agreement that it determines is

         12. INDEMNIFICATION .

                  12.1     SURVIVAL OF REPRESENTATIONS .

                           (a) The representations and warranties made by CRE
(including the representations and warranties set forth in Section .3
("Representations and Warranties of CRE") hereof and the representations and
warranties set forth in any certificate delivered by CRE in connection with this
Agreement) shall survive the Closing and shall remain in full force and effect
and shall survive until the end of the Indemnification Period and shall survive
thereafter only with respect to any claims made prior to the end of the
Indemnification Period. The representations and warranties made by Aureal and
Sub shall survive the Closing and shall remain in full force and effect and
shall survive until the end of the Indemnification Period.

                           (b) The representations, warranties, covenants and
obligations of CRE, and the rights and remedies that may be exercised by the
Indemnitees, shall not be limited or otherwise affected by or as a result of any
information furnished to, or any investigation made by or knowledge of, any of
the Indemnitees or any of their Representatives. Aureal shall deliver a



                                       38

Table of Contents, continued


certificate at the Closing certifying that it has no knowledge of any
information limiting or otherwise affecting the representations, warranties,
covenants and obligations of CRE other than that included in the CRE Disclosure
Schedule.

                           (c) For purposes of this Agreement, each statement or
other item of information set forth in the CRE Disclosure Schedule or in any
update to the CRE Disclosure Schedule accepted in writing by Aureal shall be
deemed to be a representation and warranty made by CRE in this Agreement.

         12.2 INDEMNIFICATION BY CRE SHAREHOLDERS .

                  (a) From and after the Closing Date (but subject to the
limitations in Sections .12.1(a) and .12.3 ("Threshold; Ceiling; Exclusivity"),
the shareholders of CRE (the "CRE Shareholders") shall hold harmless and
indemnify each of the Indemnitees from and against, and shall compensate and
reimburse each of the Indemnitees for, any Damages which are directly or
indirectly suffered or incurred by any of the Indemnitees or to which any of the
Indemnitees may otherwise become subject (regardless of whether or not such
Damages relate to any third-party claim) and which arise from or as a result of,
or are directly or indirectly connected with: (i) any inaccuracy in or breach of
any representation or warranty set forth in Section .3 ("Representations and
Warranties of CRE") hereunder or in any certificate delivered by CRE in
connection with this Agreement; (ii) any breach of any covenant or obligation of
CRE hereunder; or (iii) any Legal Proceeding relating to any inaccuracy, breach
or expense of the type referred to in clause "(i)" or "(ii)" above (including
any Legal Proceeding commenced by any Indemnitee for the purpose of enforcing
any of its rights under this Section .12, .12 if such Indemnitee is the
prevailing party in any such Legal Proceeding).

                  (b) If the Surviving Corporation suffers, incurs or otherwise
becomes subject to any Damages as a result of or in connection with any
inaccuracy in or breach of any representation, warranty, covenant or obligation,
then (without limiting any of the rights of the Surviving Corporation as an
Indemnitee) Aureal shall also be deemed, by virtue of its ownership of the stock
of the Surviving Corporation, to have incurred Damages as a result of and in
connection with such inaccuracy or breach.

         12.3 THRESHOLD; CEILING; EXCLUSIVITY .

                  (a) The CRE Shareholders shall not be required to make any
indemnification payment (including, without limitation, any payment from the
Bonus Fund), pursuant to Section .12.2 ("Indemnification by CRE Shareholders")
for any inaccuracy in or breach of any of the representations and warranties set
forth in Section .3 ("Representations and Warranties of CRE") hereof or in any
certificate delivered by CRE in connection with this Agreement until such time
as the total amount of all Damages (including the Damages arising 



                                       39
<PAGE>   45
Table of Contents, continued


from such inaccuracy or breach and all other Damages arising from any other
inaccuracies in or breaches of any representations or warranties) that have been
directly or indirectly suffered or incurred by any one or more of the
Indemnitees, or to which any one or more of the Indemnitees has or have
otherwise become subject, exceeds Fifty Thousand Dollars ($50,000) in the
aggregate.

                  (b) Other than with respect to fraudulent breaches or
misrepresentations, the CRE Shareholders' maximum aggregate liability under the
indemnification provisions of this Section 12, including any amounts paid from
the Bonus Fund (as provided in Section 12.4 below), shall be $2,000,000 (the
"Maximum Damages"). With respect to fraudulent breaches or misrepresentations,
there shall be no maximum liability under the indemnification provisions of this
Section 12.

                  (c) The sole and exclusive remedy for any and all Damages
suffered or incurred by an Indemnitee arising from or related to this Agreement
or the transactions contemplated herein shall be the indemnification rights set
forth in this Section 12. Notwithstanding the foregoing, each party to an
Employment Agreement shall have the rights and remedies arising from or related
to a breach or default under such Agreement as are available to such party under
law or in equity.

         12.4 SATISFACTION OF INDEMNIFICATION CLAIM . In the event the CRE
Shareholders shall have any liability (for indemnification or otherwise) to any
Indemnitee under this Section .12, .12, satisfaction of such liability shall
occur initially from the remaining proceeds in the Bonus Fund and then from the
CRE Shareholders, who shall be severally liable therefor, but in no case shall
such liability to any CRE Shareholder exceed such shareholder's pro rata share
of such liability (based on a fraction, (i) the numerator of which is the total
number of shares of CRE Common Stock owned by such shareholder at the Closing,
plus the number of shares of CRE Common Stock issuable upon exercise of any
Exercised Vested CRE Options of such shareholder, and (ii) the denominator of
which is the number of shares of CRE Common Stock outstanding at the Closing,
plus the number of shares of CRE Common Stock issuable upon exercise of the
Exercised Vested CRE Options.

         12.5 LIMITATION ON CLAIMS . In case any event shall occur which would
otherwise entitle an Indemnitee to assert a claim for indemnification hereunder,
the amount of Damages determined to have been sustained by such Indemnitee shall
be reduced by (a) any tax savings actually realized by such Indemnitee with
respect thereto after taking into account the effect for tax purposes of both
the event giving rise to such Damages and the receipt of the indemnification
payment, and (b) any proceeds received by such Indemnitee from any insurance
policies with respect thereto.

         12.6 NO CONTRIBUTION . The CRE Shareholders acknowledge and agree that




                                       40
<PAGE>   46
Table of Contents, continued



they shall not have and shall not exercise or assert (or attempt to exercise or
assert), any right of contribution, right of indemnity or other right or remedy
against the Surviving Corporation in connection with any indemnification
obligation or any other liability to which it may become subject under or in
connection with this Agreement or any certificate delivered by CRE in connection
with this Agreement.

         12.7 INTEREST . If the CRE Shareholders are required to hold harmless,
indemnify, compensate or reimburse any Indemnitee pursuant to this Section .12,
 .12 with respect to any Damages, then the CRE Shareholders shall also be liable
to such Indemnitee for interest on the amount of such Damages (for the period
commencing as of thirty (30) days after the date on which the CRE Shareholder
Representative first received notice of a claim for recovery by such Indemnitee
and ending on the date on which the liability to Indemnitee is fully satisfied
by such CRE Shareholder) at a floating rate equal to the rate of interest
publicly announced by Bank of America, N.T.& S.A. from time to time as its
prime, base or reference rate.

         12.8 DEFENSE OF THIRD PARTY CLAIMS . In the event of the assertion or
commencement by any Person of any claim or Legal Proceeding (whether against the
Surviving Corporation, against Aureal or against any other Person) with respect
to which CRE may become obligated to hold harmless, indemnify, compensate or
reimburse any Indemnitee pursuant to this Section .12, .12, the procedure set
forth below shall be followed.

                  (a) NOTICE. Aureal shall give prompt written notice of the
commencement of any such Legal Proceeding against Aureal or the Surviving
Corporation for which indemnity may be sought under Section .12, .12
("Indemnification and Escrow"); provided, however, that any failure on the part
of Aureal to so notify CRE shall not limit any of the obligations of CRE under
this Section .12, .12. The Indemnification Period shall be tolled solely with
respect to a particular claim for the period beginning on the date the
Indemnifying Party receives written notice of that claim until the final
resolution of such claim so long as such claim is made within the
Indemnification Period.

                  (b) DEFENSE OF CLAIM. The Indemnitee shall have the right to
be represented by counsel of its choice and to defend or otherwise control the
handling of any claim, or Legal Proceeding for which indemnity is sought.
Notwithstanding the foregoing, CRE may elect (by written notice by the CRE
Shareholder Representative to Aureal within fifteen (15) days after receipt of
written notice under Section .12.8 ("Defense of Third Party Claims")) to assume
the defense of or otherwise control the handling of any such claim including tax
audit for any year prior to the Closing or Legal Proceeding (other than for
matters relating to the intellectual property rights of Aureal (including CRE),
or claims by customers of Aureal) for which indemnity is sought, subject to the
limitations provided herein.




                                       41
<PAGE>   47
Table of Contents, continued



If the CRE Shareholders so elect to assume the defense of any such claim or
Legal Proceeding:

                           (i) the CRE Shareholders shall proceed to defend such
claim or Legal Proceeding in a diligent manner with counsel reasonably
satisfactory to the Indemnitee, and all expenses relating to the defense of such
claim or Legal Proceeding shall be borne and paid exclusively by the CRE
Shareholders;

                           (ii) the Indemnitee shall make available to the CRE
Shareholders any non-privileged documents and materials in the possession of the
Indemnitee that may be necessary to the defense of such claim or Legal
Proceeding;

                           (iii) the CRE Shareholders shall keep the Indemnitee
informed of all material developments and events relating to such claim or Legal
Proceeding;

                           (iv) the Indemnitee shall have the right to
participate in the defense of such claim or Legal Proceeding at its sole cost
and expense; and

                           (v) the CRE Shareholders shall not be entitled to
settle, adjust or compromise such claim or Legal Proceeding without the prior
written consent of the Indemnitee, so long as the Indemnitee has any
responsibility for such claim or Legal Proceeding or has the right to bring any
claim in response to such claim or Legal Proceeding.

If the CRE Shareholders do not (or cannot) elect to assume the defense of any
such claim or Legal Proceeding, the Indemnitee may proceed with the defense of
such claim or Legal Proceeding on its own. If the Indemnitee so proceeds with
the defense of any such claim or Legal Proceeding on its own:

                           (vi) all expenses relating to the defense of such
claim or Legal Proceeding (whether or not incurred by the Indemnitee) shall be
borne and paid exclusively by the CRE Shareholders;

                           (vii) the CRE Shareholders shall make available to
the Indemnitee any documents and materials in the possession or control of the
CRE Shareholders that may be necessary to the defense of such claim or Legal
Proceeding except for documents or materials which are sealed by a court order
or are subject to a nondisclosure agreement prohibiting disclosure by the CRE
Shareholders;

                           (viii) the Indemnitee shall keep the CRE Shareholders
informed of all material developments and events relating to such claim or Legal
Proceeding; and

                           (ix) the Indemnitee shall not have the right to
settle, adjust or 



                                       42
<PAGE>   48
Table of Contents, continued


compromise such claim or Legal Proceeding without the consent of the CRE
Shareholders; provided, however, that the CRE Shareholders shall not
unreasonably withhold such consent.

         12.9 EXERCISE OF REMEDIES BY INDEMNITEES OTHER THAN AUREAL . No
Indemnitee (other than Aureal or any successor thereto or assignee thereof)
shall be permitted to assert any indemnification claim or exercise any other
remedy under this Agreement unless Aureal (or any successor thereto or assign
thereof) shall have consented to the assertion of such indemnification claim or
the exercise of such other remedy.

         12.10 CRE SHAREHOLDER REPRESENTATIVE .

                  (a) Subject to the limitations on indemnification contained in
this Section 12, the Bonus Fund shall be available to compensate Aureal for any
Damages, to the extent of the amount of Damages that Aureal has incurred by
reason of the breach of CRE of any representation, warranty, covenant or
agreement of CRE contained herein, or by reason of any misrepresentation by CRE
made in or pursuant to Section 3 ("Representations and Warranties of CRE") of
this Agreement or in any certificate delivered by CRE pursuant to this
Agreement.

                  (b) By virtue of their approval of this Agreement, the
shareholders of CRE will be deemed to have irrevocably constituted and
appointed, effective as of the Effective Time, Scott Foster (together with his
permitted successors, the "CRE Shareholder Representative"), as their true and
lawful agent and attorney-in-fact to enter into any agreement in connection with
the transactions contemplated by this Agreement or amounts demanded from the
Bonus Plan to exercise all or any of the powers, authority and discretion
conferred on him under any such agreement, to waive any terms and conditions of
any such agreement to give and receive notices and communications, to agree to,
negotiate, enter into settlements and compromises of, and demand arbitration and
comply with orders of courts and awards of arbitrators with respect to such
claims, and to take all actions necessary or appropriate in the judgment of the
CRE Shareholder Representative for the accomplishment of the foregoing. No bond
shall be required of the CRE Shareholder Representative, and the CRE Shareholder
Representative shall receive no compensation for his services. Notices or
communications to or from the CRE Shareholder Representative shall constitute
notice to or from each of the CRE Shareholders. This power of attorney is
coupled with an interest and is irrevocable.

                  (c) The CRE Shareholder Representative shall not be liable for
any act done or omitted hereunder as CRE Shareholder Representative while acting
in good faith and not in a manner constituting gross negligence, and any act
done or omitted pursuant to the advice of counsel shall be conclusive evidence
of such good faith. The CRE Shareholders shall severally indemnify the CRE
Shareholder Representative and hold him harmless against any loss, liability or
expense incurred without gross negligence or bad faith on the part of the CRE
Shareholder Representative and arising out of or in connection with the
acceptance or administration of his 





                                       43
<PAGE>   49
Table of Contents, continued


duties hereunder. Notwithstanding anything contained in this Agreement to the
contrary, in no event shall Scott Foster, acting as the CRE Shareholder
Representative, have any liability arising from any act or omission as
representative in excess of the maximum indemnification amount he could be
responsible for pursuant to Section 12.3.

         13. MISCELLANEOUS .

                  13.1 GOVERNING LAWS . It is the intention of the parties
hereto that the internal laws of the State of California (irrespective of its
choice of law principles) shall govern the validity of this Agreement, the
construction of its terms, and the interpretation and enforcement of the rights
and duties of the parties hereto. The parties hereby agree that any suit to
enforce any provision of this Agreement or arising out of or based upon this
Agreement or the business relationship between any of the parties hereto brought
by CRE or Aureal shall be brought in the United States District Court for the
Northern District of California or the Superior or Municipal Court in and for
the County of Santa Clara, California. Each party hereby agrees that such
courts, as applicable, shall have in personam jurisdiction with respect to such
party, and such party hereby submits to the personal jurisdiction of such
courts.

                  13.2 BINDING UPON SUCCESSORS AND ASSIGNS . Subject to, and
unless otherwise provided in, this Agreement, each and all of the covenants,
terms, provisions, and agreements contained herein shall be binding upon, and
inure to the benefit of, the permitted successors, executors, heirs,
representatives, administrators and assigns of the parties hereto.

                  13.3 SEVERABILITY . If any provision of this Agreement, or the
application thereof, shall for any reason and to any extent be invalid or
unenforceable, the remainder of this Agreement and application of such provision
to other persons or circumstances shall be interpreted so as best to reasonably
effect the intent of the parties hereto. The parties further agree to replace
such void or unenforceable provision of this Agreement with a valid and
enforceable provision which will achieve, to the extent possible, the economic,
business and other purposes of the void or unenforceable provision.

                  13.4 ENTIRE AGREEMENT . This Agreement, the exhibits hereto,
the documents referenced herein, and the exhibits thereto, constitute the entire
understanding and agreement of the parties hereto with respect to the subject
matter hereof and thereof and supersede all prior and contemporaneous agreements
or understandings, inducements or conditions, express or implied, written or
oral, between the parties with respect hereto and thereto. The express terms
hereof control and supersede any course of performance or usage of the trade
inconsistent with any of the terms hereof.

                  13.5 COUNTERPARTS . This Agreement may be executed in any
number of counterparts, each of which shall be an original as against any party
whose signature appears 







                                       44
<PAGE>   50
Table of Contents, continued


thereon and all of which together shall constitute one and the same instrument.
This Agreement shall become binding when one or more counterparts hereof,
individually or taken together, shall bear the signatures of all of the parties
reflected hereon as signatories.

                  13.6 EXPENSES . Except as provided to the contrary herein,
each party shall pay all of its own costs and expenses incurred with respect to
the negotiation, execution and delivery of this Agreement and the exhibits
hereto.

                  13.7 OTHER REMEDIES . Except as otherwise provided herein, any
and all remedies herein expressly conferred upon a party shall be deemed
cumulative with and not exclusive of any other remedy conferred hereby or by law
on such party, and the exercise of any one remedy shall not preclude the
exercise of any other. Notwithstanding the foregoing, if the Closing occurs, the
sole and exclusive remedy of Aureal and Sub shall be as set forth in Section
 .12, .12 ("Indemnification and Escrow").

                  13.8 AMENDMENT AND WAIVERS . Any term or provision of this
Agreement may be amended, and the observance of any term of this Agreement may
be waived (either generally or in a particular instance and either retroactively
or prospectively) only by a writing signed by the party to be bound thereby. The
waiver by a party of any breach hereof for default in payment of any amount due
hereunder or default in the performance hereof shall not be deemed to constitute
a waiver of any other default or any succeeding breach or default.

                  13.9 SURVIVAL OF AGREEMENTS . Subject to Section .12.1(a), all
covenants, agreements, representations and warranties made herein shall survive
the execution and delivery of this Agreement and the consummation of the
transactions contemplated hereby notwithstanding any investigation of the
parties hereto.

                  13.10 NO WAIVER . The failure of any party to enforce any of
the provisions hereof shall not be construed to be a waiver of the right of such
party thereafter to enforce such provisions.

                  13.11 ATTORNEYS' FEES . Should suit be brought to enforce or
interpret any part of this Agreement, the prevailing party shall be entitled to
recover, as an element of the costs of suit and not as damages, reasonable
attorneys' fees to be fixed by the court (including, without limitation, costs,
expenses and fees on any appeal). The prevailing party shall be the party
entitled to recover its costs of suit, regardless of whether such suit proceeds
to final judgment. A party not entitled to recover its costs shall not be
entitled to recover attorneys' fees. No sum for attorneys' fees shall be counted
in calculating the amount of a judgment for purposes of determining if a party
is entitled to recover costs or attorneys' fees.

                  13.12 NOTICES . Any notice provided for or permitted under
this Agreement will

                              [AUREAL LETTERHEAD]




                              FOR IMMEDIATE RELEASE

             AUREAL SEMICONDUCTOR ACQUIRES CRYSTAL RIVER ENGINEERING


         FREMONT, CALIFORNIA -- MAY 8, 1996 -- (MVSN: OTC Bulletin Board) Aureal
Semiconductor announced today that it has entered into an agreement to acquire
Crystal River Engineering ("CRE"), a privately held, leading developer of True
Positional 3D audio technology. The acquisition was accomplished through a
merger of CRE with an existing Aureal subsidiary. Under the merger, Aureal will
incorporate CRE's technologies into Aureal's future product releases and will
continue to develop, market and promote CRE's existing product offering under
the CRE name. The financial terms of the transaction were not disclosed.

         "We are extremely excited about joining forces with CRE and providing
3D audio solutions beyond the level of existing products in the market today"
stated Kip Kokinakis, Aureal's President and CEO. "This merger strengthens our
existing licensing relationship and expands the capabilities of our respective
hardware and software technologies to provide a higher level of interactive
audio solutions for the PC and Home Entertainment market segments. We strongly
believe that CRE's positional 3D audio technology is the best available, and we
are committed to proliferating this technology through our worldwide sales and
marketing network," added Kokinakis.

         CRE, founded in 1987, develops and markets - interactive, positional
3D audio technology and related systems under the AudioReality(TM) 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(TM), 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.

         Both Aureal and CRE expect exciting market opportunities for positional
3D audio. This belief has been strengthened by the public statements by Apple
and Microsoft that they intend to provide support for 3D audio technologies in
their future operating systems; by the inclusion of positional 3D audio in VRML
(virtual reality modeling language - the specification for browsing 3D worlds on
the world wide web), by recently disclosed plans from Dolby Labs to bring
surround sound multi-dimensional sound tracks to PCs and other interactive
entertainment platforms, as well as by the emergence of affordable interactive
3D graphics solutions (the visual counterpart to positional 3D audio).

         "This combination of resources is much more valuable than the two
companies working separately," stated Scott Foster, CRE's Chairman and CEO. "The
merger with Aureal provides the environment which will allow us to continue our
research as well as significantly expand the market for our existing technology.
In addition, the integration of CRE's true positional 3D and Aureal's ongoing
advanced synthesis technology is intended to provide audio realism beyond
today's standards." Mr. Foster will become General Manager of Crystal River
Engineering and Vice President of Aureal.

         Forward-looking statements in this release are made pursuant to the
safe harbor provisions of the Private Securities Act of 1995. Investors are
cautioned that such forward-looking statements involve risks and uncertainties,
including, but not limited to, dependence on new technology, on foundry capacity
availability and reliability; on the PC industry and on a single product line;
dependence on a new management team; competition and pricing pressures; and
other risks detailed from time to time in the company's periodic reports filed

         Aureal Semiconductor designs, develops and markets advanced audio
solutions for the PC and Consumer markets The company's initial products are
targeted to implement Windows Direct Sound acceleration, digital mixing, True
Positional 3D audio, and a wide-range of other sound processing effects and
algorithms
