AUREAL INC.
NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

1.   THE COMPANY

     Aureal Inc., together with our subsidiaries Crystal River Engineering, Inc.
and Aureal Limited, is a producer of digital audio semiconductor and board-level
products and advanced digital audio technologies primarily for the personal
computer market. Crystal River Engineering, which was founded in 1987 and which
we acquired in the second quarter of 1996, has been a pioneer in the development
of 3D audio technologies. We established Aureal Limited, located in Hong Kong,
in March 1998 as a sales, technical support and field engineering office. Our
business involves the development and sale of audio processing semiconductor
chips and audio-based add-in cards for use in PCs, as well as the licensing of
technology that is designed to define and develop advanced audio standards in
the marketplace. Our stock symbol on the OTC Bulletin Board is AURL.

2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

     Basis of Presentation

     We, the management of Aureal Inc., have prepared the following Interim
Condensed Consolidated Financial Statements without audit, pursuant to the rules
and regulations of the Securities and Exchange Commission. Certain information
and footnote disclosures normally included in the financial statements prepared
in accordance with generally accepted accounting principles have been omitted
pursuant to such rules and regulations. The disclosures included in the Interim
Condensed Consolidated Financial Statements should be read in conjunction with
our audited financial statements at January 3, 1999 and the financial footnotes
included in our 1998 Annual Report on Form 10-K.

     The preparation of financial statements in conformity with generally
accepted accounting principles and pursuant to the rules and regulations of the
Securities and Exchange Commission requires us to make estimates and assumptions
that affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of revenues and expenses during the reporting periods.
Actual results could differ from those estimates.

     The Interim Condensed Consolidated Financial Statements reflect, in our
opinion, all adjustments, which include only normal recurring adjustments,
necessary for a fair presentation of financial position, results of operations
and cash flows for such periods. The results of operations for the fiscal
quarter ended October 3, 1999 are not necessarily indicative of the results that
may be expected for the subsequent quarter or the entire fiscal year ending
January 2, 2000.

     Cash and Cash Equivalents and Short Term Investments

     We consider cash invested in highly liquid financial instruments with an
original maturity of three months or less to be cash equivalents. Cash
investments in highly liquid financial instruments with original maturities
greater than three months but not longer than fifteen months are classified as
short-term investments.

     Inventories

     Inventories are stated at the lower-of-cost-or-market value on a first-in
first-out basis. We do not consider any inventory to be raw material, since our
initial point of purchase is for fabricated silicon wafers. Net inventories at
October 3, 1999 and January 3, 1999 consisted of the following, in thousands:

</TABLE>



                                       6
<PAGE>   7

     Property and Equipment

     Property and equipment are stated at cost and depreciated utilizing the
straight-line method over their estimated useful lives (one and one-half to five
years). Leasehold improvements are amortized utilizing the straight-line method
over their estimated useful lives or the term of the lease whichever is shorter.
Maintenance and repairs are expensed as incurred.

     Revenue Recognition

Our major sources of revenue consist of sales of proprietary design, advanced
audio semiconductor chips and boards, and licensing of related audio
technologies. Revenue is recognized upon shipment for product sales. Licensing
revenues are recognized upon delivery of licensed product if a non-cancelable
contract has been signed, the fees are fixed and determinable, collection of the
recognized fees is probable, and there are no remaining significant obligations.

     Comprehensive income

     Statement of Financial Accounting Standards No. 130 requires that we
disclose all non-owner changes in equity, such as cumulative foreign currency
translation adjustments, certain minimum pension liabilities and gains and
losses on available-for-sale securities. During the first nine months of both
1999 and 1998, we had no significant elements of comprehensive income.

     Concentration of Financial Instrument Risks and Credit Risks

     Financial instruments which potentially subject us to concentration of
market risk consist primarily of our line of credit. Concentration of market
risk on the line of credit is related to changes in the prime lending rate, as
the majority of our debt bears interest at rates that fluctuate with changes in
the prime lending rate. Our credit risk consists primarily of trade receivables.
Some of these trade receivables are the result of sales to foreign companies. We
have established an allowance for doubtful accounts based on the credit risks of
the business in general.

     Valuation of Warrants

     In connection with the establishment of a credit facility in June 1998, we
issued warrants to purchase 1.35 million shares of our common stock. The fair
value of these warrants was estimated utilizing the Black-Scholes valuation
method as approximately $1.8 million. This value was being amortized over the
two-year term of the credit facility. These warrants were issued in
consideration of the Tranche B portion of this credit facility. When the Tranche
B portion of this credit facility was terminated in May 1999, the remaining
unamortized value of $0.9 million was expensed.

     Loss Per Share

     The Financial Accounting Standards Board has issued Statement of Financial
Accounting Standards No. 128, which requires that the calculation for basic
earnings per share exclude the dilutive effect of common stock equivalents in
the calculation for basic net income (loss) per share. Diluted earnings per
share under Statement of Financial Accounting Standards No. 128, is calculated
using the weighted average number of common shares and common stock equivalent
shares outstanding during the period. Common equivalent shares are computed
using the treasury stock method for outstanding warrants and stock options.
Common equivalent shares are excluded from the diluted earnings per share
computation only if their effect is anti-dilutive. No common stock equivalents
were included in the calculations for any fiscal period presented, as due to our
net loss position, any affect would be anti-dilutive.

     Accretion related to the beneficial conversion features of the series A
preferred stock and the series C preferred stock, and the dividend / accretion
rate of 8% on the series A, series B and series C preferred stock totaled $1.5
million during the first three quarters of 1999. These charges were recorded
directly to accumulated deficit and are included as a component of net loss per
share attributable to common stockholders.

     Loss per share figures for prior periods have been restated to reflect the
effect of the one-for-fifteen reverse stock split effected June 10, 1999.



                                       7

3.   CREDIT FACILITY

     Effective September 30, 1999, our existing line of credit was amended to
(1) increase the total availability to $25.0 million, (2) add PNC Bank, National
Association as an additional lender with Transamerica Business Credit
Corporation, and (3) reduce the interest rate on borrowings to prime plus 2%. In
addition, the amended line of credit provides for the issuance of standby
letters of credit up to a limit of $1.5 million. As part of this line expansion,
an affiliate of Oaktree Capital Management, LLC provided to the lenders a
guarantee, on behalf of Aureal, for up to $5.0 million of availability, which is
not subject to specific asset-based requirements. The lenders under the credit
facility hold a lien against substantially all of Aureal's assets. We are
subject to certain covenant restrictions under this facility. This agreement is
scheduled to terminate on July 2, 2001.

4.   EQUITY FUNDING

     During the second quarter of this year, we effected a capital restructuring
plan which included a subscription rights offering, the conversion of our
outstanding series B preferred stock to common stock and a one-for-fifteen
reverse stock split. Under the subscription rights offering, we offered for sale
$20 million of our common stock, at a price of $0.60 per share (pre-reverse
split). Stockholders of our common stock on April 22, 1999 were offered, on a
pro-rata basis, the opportunity to purchase new shares of our common stock. Our
two largest stockholders, Oaktree Capital Management LLC and TCW Special
Credits, agreed to purchase any unsubscribed shares of this rights offering up
to a maximum amount of $20 million. Oaktree and TCW, holders of all of our
series B preferred stock, converted their shares of series B preferred stock
into 20.5 million shares of common stock upon the closing of the rights
offering. In consideration of this conversion, we issued an additional 26.2
million shares of common stock to these holders. We did not register these
additional 26.2 million shares, but we granted standard demand and piggyback
registration rights to Oaktree and TCW. As a result of these actions, most of
our preferred stock converted to common stock. We also effected the
one-for-fifteen reverse stock split on June 10, 1999, at which point, we had
9,960,577 shares outstanding.

5.   INCOME TAXES

     We were not required to provide for income taxes in the first three
quarters of 1999 or 1998 due to our net operating losses. No tax benefit has
been recorded for the losses due to the uncertainty as to the realizability. At
January 3, 1999, we had available net operating loss carryforwards of
approximately $308 million to reduce future taxable income.

6.   INDUSTRY SEGMENTS AND MAJOR CUSTOMERS

     We operate in a single segment, which includes three product revenue
groups. During the third quarter of 1999, we generated $3.2 million in revenues
from the sale of semiconductor chips, $7.7 million from the sale of board-level
products and $0.3 million in revenues from licensing agreements. During the same
period in 1998, revenues from semiconductor chips were $5.7 million, with $1.7
million from board-level products and $0.1 million from licensing agreements and
miscellaneous audio revenues.

OVERVIEW

     Aureal Inc., together with our subsidiaries Crystal River Engineering, Inc.
and Aureal Limited, is a producer of digital audio semiconductor and board-level
products and advanced digital audio technologies for the personal computer
market. We contract with independent silicon manufacturers, which in the
semiconductor industry are called foundries, for production of our semiconductor
products, and thus we do not fabricate our own semiconductor products. The
foundry that manufactures the majority of our semiconductor products is one of
the three largest foundries in the world that manufactures products exclusively
for outside customers. Our objective is to be a leading provider of advanced
digital audio solutions for the personal computer market.

     To date in 1999, a number of significant events occurred for us:

- -    During September 1999, we announced and began shipping two new audio
     boards, the Vortex SQ1500 and the Vortex2 SQ2500, for the retail market. We
     are distributing these boards initially through a number of national
     electronics retailers as well as our e-commerce website.
- -    In August 1999, we moved our Fremont operations into a larger building,
     which we have leased for a minimum of two and one-half years. We have
     options to extend the lease, if the sub-lessor agrees, at the time of the
     extension.
- -    In June 1999, we completed a capital restructuring which included a $20
     million subscription rights offering of common stock, the conversion of all
     of our series B and C preferred stock and a one-for-fifteen reverse stock
     split.
- -    In May 1999, our stockholders voted to change our name from Aureal
     Semiconductor Inc. to Aureal Inc. We believe our new name more accurately
     reflects our focus as a digital audio imaging hardware and software
     company.
- -    Also in May 1999, we announced the introduction of the Vortex Advantage
     soundcard - a new, low-cost audio sub-system for systems integrators.
- -    In April 1999, we announced that Sony Electronics had begun shipping two
     new VAIO brand PCs incorporating our Vortex2 audio processors. With the
     introduction of these machines, Sony became the first manufacturer to
     design Vortex2 audio processors directly onto a PC motherboard.
- -    Also in April 1999, we announced the availability of a new digital audio
     accelerator for desktop and notebook PCs, the Vortex AU8810. This new chip
     is a low-cost, motherboard solution resulting from the integration of audio
     and modem capabilities.
- -    In March 1999, we released our A3D 2.0 software development kit, which
     enables the creation of interactive 3D audio content, to the general
     development community. This kit had previously only been available to
     selected game developers.
- -    Also in March 1999, we announced the formation of a partnership with
     Flatland Online, Inc. As part of this partnership, we have integrated our
     A3D 2.0 standard into Flatland's tools and web browser extension software
     providing easy-to-use positional audio for the 3D web enhanced by our
     Aureal Wavetracing technology.
- -    In February 1999, we received Computer Gaming World's prestigious Gaming
     Hardware of the Year award for our Vortex2 audio processor. This was the
     first time that the award was presented to an audio hardware company. Also
     in February, we began web-based distribution of our A3D Pro sound design
     software
- -    In January 1999, we began direct sales to systems integrators. We also
     announced an extension of our relationship with Compaq Computer
     Corporation, in which Compaq agreed to ship our Vortex sound card products
     in their new Presario 5600 desktop computer products.

     We are headquartered in Fremont, California and have offices in Austin,
Texas and Hong Kong. As of November 1, 1999, we employed 128 people. Of this
total, 78 were engaged in engineering functions, 34 were in sales and marketing
activities, and 16 were engaged in administrative support. In addition, we

RESULTS OF OPERATIONS

Third quarter and nine months of 1999 compared to the third quarter and nine
months of 1998

         Net sales

         Net sales for the third quarter of 1999 of $11.2 million increased 48%
over the $7.5 million generated in the same quarter of 1998. The sales increase
reflected increased volumes of products shipped to many of our OEM and system
integrator customers, as well as initial shipments of our Vortex SQ1500 and
Vortex2 SQ2500 audio boards to the retail market. Year-to-date revenues for 1999
of $31.8 million more than doubled the $14.6 million 1998 amount. The most
significant area of growth from 1998 to 1999 has been the emergence of Aureal's
board-level products. Board-level products accounted for 69% of our revenues in
the third quarter and 61% year-to-date, as compared to 22% for the same quarter
and 11% year-to-date in 1998. Audio boards, including an Aureal audio
semiconductor chip, generally have a higher average selling price than a direct
chip sale. All of our system integrator and retail revenues consist of
board-level sales, and our OEM revenues consist of both chip and board-level
sales. In addition, sales of audio chips to manufacturers of PC "motherboards"
are an increasing portion of our quarterly sales. Licensing revenue in all
periods discussed was not significant.

         Gross margin

         Gross margin for both the third quarter and year-to-date in 1999 was
36%. The gross margin on the sale of our products for any period is affected by
both the margins on the individual products and the mix of products sold during
the period. In addition, the market into which a product is sold, OEM, system
integrator or retail, can have an impact on the gross margin recognized on any
specific product. Gross margins for the third quarter and year-to-date in 1998
were 28% and 30%, respectively. Gross margins were adversely affected in 1998
due to costs incurred in the "start-up" phase of the AU8830 chip. We have
experienced some reductions in the cost of the chips and surrounding processing
as a result of the manufacturing maturity and increasing volumes of parts being
manufactured during 1999.

         Research and development

         Expenditures for research and development continue to be significant as
resources are allocated to create future audio products and technologies.
Spending in this area yields both short-term and long-term product developments
as we continue to bring new and improved products to the market. Research and
development expenses increased from $3.0 million in the third quarter of 1998 to
$5.3 million in the third quarter of 1999. During the third quarter of 1999, we
incurred significant expenditures for chip and audio technology development. In
addition, we invested in the development of new audio loudspeaker and internet
audio technologies. The Aureal Vortex Player, a software package designed to
provide full internet audio capabilities over time, began shipping with our
Aureal Vortex boards late in the third quarter of 1999. Year-to-date research
and development expenditures increased 44% from $8.5 million for the first nine
months of 1998 to $12.3 million for the first nine months of 1999. Certain
development efforts ended late in the third quarter and early fourth quarter of
1999. As a result, some reductions in force, both employees and outside
contractors and consultants, are being made during the fourth quarter to reduce
costs on certain programs going forward. We expect research and development to
continue to be a significant area of investment for us as we develop new audio
technologies and products.

         Sales and marketing

         During the third quarter of 1999, we continued our direct sales efforts
to expand our presence in the system integrator channel. In addition, toward the
end of the quarter we incurred expenses related to the introduction of our new
Vortex SQ1500 and Vortex2 SQ2500 audio boards in the retail market. This effort
included development of Aureal's own retail e-commerce website as well as
advertising and promotional expenditures that focused on Aureal's entry into the
retail audio board market. While year-to-date sales and marketing expenses
increased in absolute dollar terms from $4.5 million in 1998 to $7.7 million in
1999, these costs decreased as a percentage of net sales from 31% in 1998 to 24%
in 1999. As we expand our distribution model and revenues increase, we expect
sales and marketing expenses will continue to increase in absolute dollars in
the future.

         General and administrative

         General and administrative expenses for the third quarter of 1999
increased to $2.2 million from $1.2 million in 1998. The most significant
individual component of this increase was legal fees, as we prepared for the
scheduled November trial against Creative Technology Ltd. relative to alleged
patent infringement. For the first nine months of 1999, general and
administrative expenses increased to $6.0 million compared to $2.9 million for
the same period of 1998, again primarily as a result of increased legal costs.

         Interest expense

         Interest expense for the third quarter of 1999 decreased to $0.2
million from $0.3 million in the same period in 1998. Relatively low interest
costs in the third quarters of both years resulted from infusions of equity
capital in the second quarters of both years, and our subsequent paydowns of
debt in June of each year. On a year-to-date basis, interest expense declined
from $2.3 million in 1998 to $1.4 million in 1999, primarily due to the reduced
debt balances as a result of the equity capital infusions in both 1998 and 1999.

         Amortization of debt-related warrants

         In connection with the establishment of a credit facility in June 1998,
we issued warrants to purchase 1.35 million (pre-reverse split) shares of our
common stock. The fair value of these warrants was estimated utilizing the
Black-Scholes valuation method as approximately $1.8 million. This value was
being amortized over the original two-year term of the credit facility. These
warrants were issued in consideration for the Tranche B portion of this credit
facility. When the Tranche B portion of this credit facility was terminated in
May 1999; the remaining unamortized value of $0.9 million was expensed.

         In August 1997, in conjunction with the expansion and extension of our
prior line of credit, we issued warrants to purchase 3.15 million (pre-reverse
split) shares of our common stock to our lenders. Using the Black-Scholes
valuation method, the estimated fair value of the warrants was determined to be
$5.0 million. This value was amortized over the estimated life of the line of
credit at the rate of $0.75 million per quarter. When the line of credit was
converted to preferred stock in June 1998, the remaining unamortized deferred
costs related to the warrants were netted against the outstanding loan balance
and eliminated as a reduction of the conversion value of the series B preferred
shares.

         Income taxes

         We were not required to provide for income taxes in either the first
nine months of 1999 or 1998, respectively, due to our net operating losses. No
tax benefit has been recorded for the net operating loss carryforwards due to
the uncertainty as to their realizability.



                                       11

LIQUIDITY AND CAPITAL RESOURCES

         As of October 3, 1999, we had a working capital deficit of $2.0
million, classifying all outstanding balances under our line of credit as
current liabilities, and stockholders' equity of $1.2 million. We used $17.0
million of cash to support operations during the first nine months of 1999 as
compared to $21.0 million for the same period in 1998. While operating losses
were greater in 1999, investments in inventories, accounts receivable and other
current assets were reduced from the requirements for 1998.

         Financing for our 1999 year-to-date cash outlays was provided by a
combination of our line of credit and cash received from our June 1999 rights
offering. We expect that in the next twelve months we will need additional cash
to fund and expand our business and to finance additional inventory and accounts
receivable. It is extremely difficult to estimate the cash flows, and the timing
of these cash flows, due to our lack of significant sales and customer payment
history. We are working to increase revenues and control costs to provide for
positive cash flow operations in the future, however, we can make no assurances
that we will achieve such positive cash flow from operations within the near
future. We anticipate that our available line of credit will continue to provide
sufficient funding for the foreseeable future.

         On June 10, 1999, we completed a capital restructuring plan which
included a subscription rights offering, the conversion of our outstanding
series B preferred stock to common stock and a one-for-fifteen reverse stock
split. Under the subscription rights offering, we offered for sale $20 million
of our common stock, at a price of $0.60 per share (pre-reverse split).
Stockholders of our common stock on April 22, 1999 were offered, on a pro-rata
basis, the opportunity to purchase new shares of our common stock. Our two
largest stockholders, Oaktree Capital Management LLC and TCW Special Credits,
agreed to purchase any unsubscribed shares of this rights offering up to a
maximum amount of $20 million. Oaktree and TCW, holders of all of our series B
preferred stock, converted their shares of series B preferred stock into 20.5
million shares of common stock upon the closing of the rights offering. In
consideration of this conversion, we issued an additional 26.2 million shares of
common stock to these holders. We did not register these additional 26.2 million
shares, but we granted standard demand and piggyback registration rights to
Oaktree and TCW. As a result of these actions, most of our preferred stock was
converted to common stock.

         In connection with our second quarter 1999 capital restructuring, the
outstanding balance under our line of credit was re-paid and new terms were
agreed upon with Transamerica Business Credit Corporation. Effective September
30, 1999 our line of credit was amended to (1) increase the total availability
to $25.0 million, (2) add PNC Bank, National Association as an additional lender
with Transamerica Business Credit Corporation, and (3) reduce the interest rate
on borrowings to prime plus 2%. In addition, the amended line of credit provides
for the issuance of standby letters of credit up to a limit of $1.5 million. As
part of this line expansion, an affiliate of Oaktree Capital Management, LLC
provided to the lenders a guarantee, on behalf of Aureal, for up to $5.0 million
of availability, which is not subject to specific asset-based requirements. We
are subject to certain covenant restrictions under this facility. This agreement
is scheduled to terminate on July 2, 2001.

         At October 3, 1999, we had a $4.1 million outstanding balance under our
line of credit. Our unused borrowing availability under the line was $4.9
million.

DISCLOSURE REGARDING THE YEAR 2000

         Year 2000 Readiness Disclosure: Some computer, software, and other
equipment include computer code in which calendar year data is abbreviated to
only two digits. As a result of this design protocol, some of these systems
could fail to operate or fail to produce correct results if the year "00" is
interpreted to mean 1900 instead of 2000. These problems are widely expected to
increase in frequency and severity as the year 2000 approaches and are commonly
referred to as the "year 2000 problem."

Assessment:
         The year 2000 problem affects some of the computers, software and other
equipment that we use, operate or maintain for our operations. We have developed
a year 2000 readiness plan to assess our exposure to the year 2000 problem,
implement solutions and develop necessary contingency plans. This plan has been
reported to our board of directors and progress is reported to them on a regular
basis. To date we have obtained verification and validation from the majority of
our independent third party software and hardware suppliers of the year 2000
compliance of their products.



                                       12
<PAGE>   13

Internal infrastructure:
         Of the systems we are currently using, the components of our mission
critical software are year 2000 compliant as are the majority of the software
packages we employ as engineering tools.

         In addition to computers and software packages, some office equipment
such as fax machines, telephone switches, security systems and other common
devices may be affected by the year 2000 problem. Of these pieces of equipment,
we identified our voice mail system as having year 2000 issues, and upgraded it
in October 1999.

Products and software programs:
         We have tested our products for year 2000 problems. This testing was
completed during the first quarter of 1999. Our engineering staff performed
compliance testing on all A3D drivers, utilities and supporting software using
testing methods and measurements that specifically addressed potential risks to
seamless integration into the year 2000 environment. Our A3D product passed both
functional and usage tests without errors due to year 2000 non-compliance.

         We estimate the cost of completing any required modifications, upgrades
or replacements of our internal systems to not be significant. All systems that
we have tested to date are year 2000 compliant. We believe that the systems that
we have not tested can be replaced or modified in the normal course of business.

Suppliers:
         We are contacting our suppliers and checking the web sites of
third-party suppliers of components used in the manufacture of our products to
determine if these suppliers are certifying that the components they provide us
are year 2000 compliant. To date, we believe all critical components that we
obtain from third party suppliers are year 2000 compliant. We expect that we
will be able to resolve any significant year 2000 problems with any third-party
suppliers of components; however, there can be no assurance that these suppliers
will resolve any or all year 2000 problems before the occurrence of a material
disruption to the operation of our business. Any failure of these third parties
to timely resolve year 2000 problems with their systems could have a material
adverse effect on our business, operating results and financial condition.

Most likely consequences of year 2000 problems:
         We expect to identify and resolve all year 2000 problems before they
materially adversely affect our business operations; however, we believe that it
is not possible to determine with complete certainty that all year 2000 problems
affecting us have been identified or corrected. The number of devices that could
be affected and the interactions among these devices are simply too numerous. In
addition, no one can accurately predict how many year 2000 problem-related
failures will occur or the severity, duration, or financial consequences of
these perhaps inevitable failures. As a result, we believe that we could
experience a significant number of operational inconveniences and inefficiencies
for us, our contract manufacturers, and our customers that will divert
management's time and attention and financial and human resources from ordinary
business activities. We also believe that it is possible that there may be
business disputes alleging that we failed to comply with the delivery terms of
contracts.

Contingency plans:
         We will develop contingency plans to be implemented if our efforts to
correct identifiable year 2000 problems are not effective. Depending on the
systems identified as non-compliant, these plans could include: accelerated
replacement of affected equipment or software, short to medium-term use of
backup equipment and software; increased work hours for our personnel; and use
of contract personnel to correct on an accelerated schedule any year 2000
problems that arise or to provide manual workarounds for information systems.
Our implementation of any of these contingency plans could have a material
adverse effect on our business, operating results and financial condition.

Disclaimer:
         The discussion of our efforts and expectations relating to year 2000
compliance are forward-looking statements. Our ability to achieve year 2000
compliance and the level of incremental costs associated therewith, could be
adversely affected by, among other things, the availability and cost of
programming and testing resources, third party suppliers' ability to modify
proprietary software, and unanticipated problems identified in the ongoing
compliance review.

RISK FACTORS

         In addition to the other information in this report or incorporated in
this report by reference, you should consider carefully the following factors in
evaluating Aureal and our business:

WE HAVE SUSTAINED LOSSES IN THE PAST AND WE EXPECT TO SUSTAIN LOSSES IN THE
FUTURE

         We emerged from bankruptcy protection in December 1994. Since that
time, we have recorded an accumulated deficit of $191 million as of October 3,
1999. This deficit is comprised of $174 million of incurred losses and $17
million of accretion and dividends on our preferred stock. We generated the
majority of our revenues in 1997 and 1996 through technology licensing
transactions. The majority of our revenues in 1998 and the first three quarters
of 1999 were derived from the sale of advanced audio products. We expect that
the majority of our future revenues will be derived from the sale of advanced
audio products. However, we will not be profitable unless we sell significant
volumes of our advanced audio products in the future.

A DIRECTOR OF AUREAL HAS VOTING CONTROL OVER A SUBSTANTIAL AMOUNT OF OUR STOCK
AND MAY, THEREFORE, INFLUENCE OUR AFFAIRS

         As of October 3, 1999, Richard Masson, a director of Aureal, is deemed
to have voting control over approximately 77% of our common stock as a result of
his affiliations with Oaktree and TCW. Accordingly, Mr. Masson can be considered
to control all matters requiring approval by our stockholders, including the
election of directors and the approval of mergers or other business
combinations.

INVESTORS MAY FIND IT DIFFICULT TO TRADE OUR COMMON STOCK ON THE
OVER-THE-COUNTER ELECTRONIC BULLETIN BOARD

         Our common stock trades only on the Over-the-Counter Electronic
Bulletin Board. Because our common stock trades on the Bulletin Board, an
investor may find it very difficult to sell or to obtain accurate quotations as
to the market value of our common stock. Furthermore, because our common stock
is not listed on the NASDAQ National Market, trading in our common stock is also
subject to certain rules promulgated by the SEC under the Securities Exchange
Act of 1934. These rules require additional disclosure by broker-dealers in
connection with any trades involving a stock defined as a penny stock.
Generally, a penny stock is any non-NASDAQ National Market listed equity
security that has a market price of less than $5.00 per share, subject to
certain exceptions. The additional burdens imposed upon broker-dealers by such
requirements may discourage broker-dealers from affecting transactions in our
common stock and may limit the ability of purchasers of our common stock to
resell our common stock in the secondary market.

WE EXPECT THE AVERAGE SELLING PRICE OF OUR ADVANCED AUDIO PRODUCTS TO DECREASE,
WHICH MAY REDUCE GROSS MARGINS AND REVENUES

         Product prices in the audio technology industry generally decrease over
the life of a particular product. The willingness of prospective customers to
design our advanced audio products into their products depends to a significant
extent upon our ability to price our products at levels that are cost-effective
for these customers. As the markets for our products mature and competition
increases, we anticipate that prices for our advanced audio products will
decline over time. If we are unable to reduce our costs sufficiently to offset
declines in our product prices, or if we are unable to introduce new, higher
performance products with higher product prices, our gross margins and revenues
could decline.



                                       14
<PAGE>   15

WE DEPEND ON A CREDIT FACILITY TO FUND OUR BUSINESS OPERATIONS

         Because we have not been profitable to date, we have had to fund our
losses through a combination of equity and debt financings. Our current line of
credit provides for an aggregate maximum borrowing of $25.0 million. The
interest rate on the credit facility is generally the prime rate plus 2.0%.
Accordingly, while the credit facility provides us with needed working capital,
the high cost of servicing any borrowing under it could negatively affect our
liquidity. In addition, the credit facility may not be sufficient to meet our
working capital requirements. In the event we must secure capital in addition to
the line of credit, we cannot guarantee that capital will be available on
acceptable terms or at all. Our inability to secure future financing, if
necessary, would materially adversely affect our business, financial condition
and results of operations.

TO COMPETE EFFECTIVELY IN THE AUDIO TECHNOLOGY MARKET, WE NEED TO DEVELOP NEW
AUDIO TECHNOLOGIES THAT ARE WIDELY ACCEPTED BY OUR CUSTOMERS

         Our success depends on our ability to develop and market new audio
technologies aimed at advancing the level of audio quality in personal
computers. To be successful, we must timely develop new products that we can
sell at competitive prices to our customers who will design them into their
products. In order for our customers to design our advanced audio products into
their personal computers, we must:

          -    anticipate market trends;

          -    anticipate the performance and functionality requirements of our
               current and potential customers;

          -    develop and produce products that meet the timing and pricing
               requirements of our current and potential customers; and

          -    produce products that can be available in a timely manner
               consistent with our current and potential customers' development
               and production schedules.

         We have expanded our business model to provide for an increased number
of audio-related products, including audio cards and audio communications
combination cards. We anticipate continuing to increase the number of products
within our line to include additional audio cards as well as speaker products in
the future. We may require additional working capital funds for this expansion
to provide for incremental inventory and broader marketing programs. A number of
factors may limit the success of our expansion, and each could negatively impact
our business and results of operations. These factors include:

          -    the failure of the market for advanced audio products to grow;

          -    reduced demand for our products as a result of increased
               competition in this market;

          -    unforeseen technological change; and

          -    our potential failure to introduce new versions of products that
               our customers and the market accept.

         A failure to develop new audio technologies that will be accepted by
our customers could materially adversely affect our ability to generate
revenues.

NEW GENERATIONS OF MICROPROCESSORS AND OTHER NEW TECHNOLOGIES MAY DECREASE
DEMAND FOR OUR PRODUCTS

         New generations of microprocessors that are capable of performing
advanced audio functions may greatly reduce demand for our advanced audio
products. Each successive generation of microprocessors has provided increased
performance, which could, in the future, result in a microprocessor capable of
performing advanced audio functions to an extent that diminishes or eliminates
the need or preference for our products. In addition, each new generation of
technology, including digital audio technology, generally requires increased
processing power. The increased capabilities of microprocessors in the future
may lower demand for our products which will materially adversely affect our
business, financial condition and results of operations.

INTENSE COMPETITION IN THE MARKET FOR ADVANCE AUDIO PRODUCTS AND TECHNOLOGIES
COULD PREVENT US FROM INCREASING REVENUE AND ACHIEVING PROFITABILITY

         The markets for advanced audio products and technologies are intensely
competitive and are characterized by evolving industry standards that result in:

          -    short product life cycles,

          -    significant pressure to improve price and performance; and

          -    frequent new product introductions.



                                       15
<PAGE>   16

         We expect competition to increase from existing competitors and from
other companies that may enter the markets for advanced audio products with
devices that may be less costly or provide higher performance or additional
features than the products we currently offer. However, we are unable to predict
the timing and nature of any such competitive product offerings.

         In addition, we anticipate that we will compete for the development of
new technologies and for the sale of semiconductor products with a number of
companies who have more extensive resources, including financial, manufacturing,
technical, marketing and distribution. Furthermore, some of these competitors
have greater intellectual property rights, broader product lines and
longer-standing relationships with their customers than we do. In addition to
our established competitors, we may also face competition from a number of
emerging companies. To remain competitive, we believe we must, among other
things, invest significant resources in developing new products and enhancing
our current products and maintaining customer satisfaction. If we fail to do so,
our products will not compete favorably with those of our competitors and our
revenue could be materially adversely affected.

WE MAY NOT HAVE AN ADEQUATE SUPPLY OF OUR PRODUCTS BECAUSE WE DEPEND ON
FOUNDRIES AND FACTORIES TO PRODUCE OUR PRODUCTS AND OUR PRODUCTS ARE DIFFICULT
TO MANUFACTURE

         We do not manufacture our own products, and we depend on outside
manufacturing resources for production of all of our products. Currently, we
utilize one foreign semiconductor foundry and one contract manufacturer for
production of our board level products. These facilities have indicated to us
that they have the manufacturing availability to provide for our planned levels
of production of each of our products for the next 12 months; however, our
production relationship with them is based only upon purchase orders.
Consequently, they may not continue to adequately provide manufacturing capacity
to us for our current level of production or any potential increases in our
production levels. In the event that they cease to manufacture our products, we
would have to contract with alternative facilities. However, we may not be able
to timely contract with alternative facilities or to contract with them at all.
Such a situation could materially adversely affect our ability to sell products
to our customers, which in turn would materially adversely affect our financial
condition and results of operations.

         During September 1999, Taiwan sustained significant damage as a result
of a major earthquake and related aftershocks. The foundry we depend upon for
our semiconductor products is located in Taiwan. It sustained some damage and
was non-operational for a number of days due to power outages. While there was
some minor delay in the delivery of some chips in process at the time of the
earthquake, no significant impact to our chip delivery schedule is currently
expected as a result of the earthquake. Other factories that supply a number of
electronic components to the PC industry were impacted to various degrees by the
earthquake and resultant power outages. While we are not aware of any specific
product shortages that may adversely impact our products, as a result of the
earthquake, these shortages may occur. If the events in Taiwan impact the
availability of components for our products, the manufacture of our products
could be delayed, which could adversely impact our business.

         The manufacture of semiconductor products is a highly complex and
precise process. Minute levels of contaminants in the manufacturing environment,
defects in the masks used to print circuits on wafers, difficulties in the
fabrication process and other factors can cause a substantial percentage of
wafers to be rejected or a significant number of die on each wafer not to
function. Many of these problems are difficult to diagnose and potentially
time-consuming or expensive to remedy. The foundries that we employ may, in the
future, experience irregularities or adverse yield fluctuations in the
manufacturing processes of our products. In such event, our business, financial
condition and results of operations may be materially adversely affected.

OUR CHARTER DOCUMENTS AND DELAWARE LAW MAY INHIBIT A TAKEOVER OF AUREAL

         Provisions in our amended and restated certificate of incorporation and
bylaws may have the effect of delaying or preventing a change of control or
changes in our management. These provisions include, among others:

          -    the division of the board of directors into three separate
               classes;

          -    the right of the board to elect the director to fill a space
               created by the expansion of the board;

          -    the ability of the board to alter our bylaws; and

          -    the requirement that at least 10% of the outstanding shares are
               needed to call a special meeting of stockholders.

         Furthermore, because we are incorporated in Delaware, we are subject to
the provisions of section 203 of the Delaware General Corporation Law. These
provisions prohibit certain large stockholders, in particular those owning 15%
or more of the outstanding voting stock, from consummating a merger or
combination with a



                                       16
<PAGE>   17

corporation unless (1) 66 2/3% of the shares of voting stock not owned by this
large stockholder approve the merger or combination or (2) the board of
directors approves the merger or combination or the transaction which resulted
in the large stockholder owning 15% or more of our outstanding voting stock.

WE MAY NOT BE ABLE TO RETAIN OUR KEY ENGINEERING, MARKETING, SALES AND
MANAGEMENT PERSONNEL THAT WE NEED TO SUCCESSFULLY MANAGE OUR BUSINESS

         Our success depends to a significant extent upon the continued services
of key engineering, marketing, sales and management personnel. Our employees may
voluntarily terminate their employment with us at any time. We recognize the
value of the contributions of each of our employees, and we have developed
compensation programs, including stock programs open to all employees, designed
to retain our employees. However, competition for these employees is intense,
particularly in Silicon Valley, and the loss of the services of any one of these
employees could materially adversely affect our business, financial condition
and results of operations.

OUR PRODUCTS EMPLOY PROPRIETARY TECHNOLOGY AND THIS TECHNOLOGY MAY INFRINGE ON
THE INTELLECTUAL PROPERTY RIGHTS OF THIRD PARTIES

         Our ability to compete successfully will depend, in part, on our
ability to protect our proprietary technology. We rely on a combination of
patents, trade secrets, copyright and trademark laws, nondisclosure agreements
and other contractual provisions and technical measures to protect our
proprietary rights. Nevertheless, such measures may not be adequate or safeguard
the proprietary technology underlying our advanced audio products. In addition,
employees, consultants and others who participate in the development of our
products may breach their agreements with us regarding our intellectual
property, and we may not have adequate remedies for any such breach. We also
realize that our proprietary information and trade secrets may become known
through other means not currently foreseen by us. Moreover, notwithstanding our
efforts to protect our intellectual property, our competitors may be able to
develop products that are equal or superior to our products without infringing
on any of our intellectual property rights. In addition, we may not be able to
effectively protect our intellectual property rights in certain countries. Our
failure to protect our proprietary technology may materially adversely affect
our financial condition and results of operations.

         Although we do not believe that our products infringe the proprietary
rights of any third parties, third parties may still assert infringement or
invalidity claims, or claims for indemnification resulting from infringement
claims, against us. The assertion of these claims could materially adversely
affect our business, financial condition and results of operations. In addition,
irrespective of the validity or the successful assertion of any claims, we could
incur significant costs in defending against these claims. In defending claims
of alleged infringement, we could incur significant expenses and waste resources
that could have a material adverse affect on our business, financial condition
and results of operations.

WE ARE INVOLVED IN LAWSUITS WITH CREATIVE AND E-MU WHICH COULD NEGATIVELY IMPACT
OUR BUSINESS

         In February 1998, Creative Technology Ltd. and its subsidiary, E-Mu
Systems, Inc., served us with a lawsuit alleging patent infringement that
Creative and E-Mu filed in the U.S. District Court, Northern District of
California. The lawsuit asserts that our original Vortex product infringes on a
patent that describes a specific implementation for an electronic musical
instrument designed by E-Mu. Creative and E-Mu seek, among other things, a
preliminary and permanent injunction against alleged continuing acts of
infringement by us and an accounting of damages plus interest. In response, we
filed a motion for summary judgment. In August 1998, E-Mu and Creative filed a
motion for a preliminary injunction with respect to our original Vortex and
updated Vortex2 products. In October 1998, the court denied Creative's motion
for preliminary injunction. At that time, our motion for summary judgment was
also denied. We believe that the actions that Creative and E-Mu filed are
without merit, and we are vigorously defending against these actions. The case
is currently scheduled for trial in November 1999.

         In December 1998, we filed a lawsuit alleging patent infringement
against Creative and E-Mu. We believe that Creative and E-Mu have infringed on
two of our patents, Patent No. 5,596,644 entitled "Method and Apparatus for
Efficient Presentation of Hi-Quality 3-Dimensional Audio" and Patent No.
5,802,180 entitled "Method and Apparatus for Efficient Presentation of
3-Dimensional Audio Including Ambient Effects."

         Additional litigation may be necessary to resolve the claims asserted
by Creative and E-Mu and to resolve our claims against Creative and E-Mu and any
other claims asserted in the future to defend against claims of



                                       17

infringement or invalidity or to enforce and protect our intellectual property
rights. We cannot assure you that we will prevail in any litigation with either
of them. Also, any litigation, whether or not determined in our favor or settled
by us, would be costly and would divert the efforts and attention of our
management and technical personnel from normal business operations; this could
materially adversely affect our business, financial condition and results of
operations. Adverse determinations in litigation could result in the loss of our
proprietary rights, subject us to significant liabilities, require us to seek
licenses from third parties or prevent us from producing certain core products.
Any of these results could have a material adverse affect on our business,
financial condition and results of operations.

THE FAILURE OF OUR KEY SUPPLIERS AND CUSTOMERS TO BE YEAR 2000 COMPLIANT COULD
NEGATIVELY IMPACT OUR BUSINESS

         We use a number of computer software programs and operating systems in
our internal operations, including applications used in financial business
systems and various administration functions. To the extent that these software
applications contain source code that is unable to appropriately interpret the
upcoming calendar year 2000, some level of modification or even possible
replacement of such source code or applications could be necessary. Given the
current information, we currently do not anticipate that such year 2000 costs
will have a material impact upon us. We have requested and obtained information
regarding year 2000 compliance from suppliers and providers of all of our
mission critical software systems. Based on the information we currently have,
all mission critical systems appear to be year 2000 compliant. We are currently
contacting major vendors and customers to obtain year 2000 compliance
certificates. The failure of any of our key suppliers or customers to be year
2000 compliant could have a material adverse effect on our business, financial
condition and results of operations.

ITEM 3. QUALITATIVE AND QUANTITATIVE DISCLOSURE OF MARKET RISKS

     There has not been a material change in our exposure to interest rate and
foreign currency risks since the date of the 1998 Form 10-K.

Interest Rate Risk. Our expose to market risk for changes in interest rates
relate primarily to our borrowings under our line of credit and any cash
equivalents. Our line of credit calls for interest at the rate of prime plus 2%.
As of October 3, 1999, we did not hold any significant cash equivalents. During
much of the third quarter, and currently, we are a "net borrower" whereas we
utilized any daily positive cash flows to pay down our line of credit, and thus
did not hold any significant cash equivalent balances for any period of time.
Our line of credit balance as of October 3, 1999 was $4.1 million.

Foreign Currency Exchange Risk. We transact business with customers and
suppliers located in foreign countries. All of these transactions are
denominated in US dollars and therefore, we have no significant cash flows that
are transacted in foreign currencies.

PART II.  OTHER INFORMATION

ITEM 1.  LEGAL PROCEEDINGS

      In February 1998, Creative Technology Ltd. and its subsidiary, E-Mu
Systems, Inc., served us with a lawsuit alleging patent infringement that
Creative and E-Mu filed in the U.S. District Court, Northern District of
California. The lawsuit asserts that our original Vortex product infringes on a
patent that describes a specific implementation for an electronic musical
instrument designed by E-Mu. Creative and E-Mu seek, among other things, a
preliminary and permanent injunction against alleged continuing acts of
infringement by us and an accounting of damages plus interest. In response, we
filed a motion for summary judgment. In August 1998, E-Mu and Creative filed a
motion for a preliminary injunction with respect to our original Vortex and
updated Vortex2 products. In October 1998, the court denied Creative's motion
for preliminary injunction. At that time, our motion for summary judgment was
also denied. Creative appealed the denial of the preliminary injunction, and on
May 6, 1999, the Federal Court of Appeals affirmed the District Court's ruling
denying the preliminary injunction. The case is currently scheduled for trial in
November 1999. We believe that the actions that Creative and E-Mu filed are
without merit, and we are vigorously defending against these actions.

      In October 1998, Creative Labs, the U.S. based subsidiary of Creative,
filed a second lawsuit against us. This new lawsuit claims we have engaged in
"false advertising" and "unfair business practices." These complaints center
primarily on a comparison chart prepared by Aureal and published by third
parties on the world-wide-web. We believe that this action is without merit and
have commenced a vigorous defense of this action. We have filed a response
denying these allegations and filed counterclaims against Creative Labs.

      In December 1998, we filed a lawsuit alleging patent infringement against
Creative and E-Mu. We believe that Creative and E-Mu have infringed on two of
our patents, Patent No. 5,596,644 entitled "Method and Apparatus for Efficient
Presentation of Hi-Quality 3-Dimensional Audio" and Patent No. 5,802,180
entitled "Method and Apparatus for Efficient Presentation of 3-Dimensional Audio
Including Ambient Effects."

         AMENDMENT NUMBER ONE AND WAIVER TO LOAN AND SECURITY AGREEMENT


     THIS AMENDMENT NUMBER ONE AND WAIVER TO LOAN AND SECURITY AGREEMENT (this
"AMENDMENT") dated as of March ___, 1999, is entered into among AUREAL
SEMICONDUCTOR INC., a Delaware corporation ("Borrower"), on the one hand, and,
on the other hand, Agent (as hereinafter defined) and the financial institutions
(collectively, the "Lenders" and individually, a "Lender") that are signatories
to that certain Loan and Security Agreement, dated as of June 5, 1998 (as
amended, restated, supplemented, or otherwise modified from time to time, the
"Loan Agreement"), entered into between Borrower, Lenders, and TRANSAMERICA
BUSINESS CREDIT CORPORATION, a Delaware corporation, as agent (herein, in such
capacity, referred to as "Agent") for Lenders thereunder, in light of the
following:

                               W I T N E S S E T H

     WHEREAS, the Parties desire to amend the Loan Agreement, in accordance with
the amendment provisions of Section 16.1 thereof, as set forth herein;

     NOW, THEREFORE, for good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties agree to amend the
Loan Agreement, effective immediately, as follows:

1.   DEFINITIONS. Capitalized terms used herein and not otherwise defined herein
shall have the meanings ascribed to them in the Loan Agreement, as amended
hereby.

2.   AMENDMENTS TO LOAN AGREEMENT. Upon the effectiveness of this Amendment, the
parties hereby agree as follows:

     (a)  The Loan Agreement hereby is amended to add the following new Section
2.2(d):

               (d)  Anything to the contrary in the Agreement notwithstanding,
          Agent shall impose, and Borrower hereby consents to the establishment
          of, a reserve against the Maximum Tranche B Amount equal to 35% of the
          Maximum Tranche B Amount (i.e., $2,625,000.00). Agent may not change
          the amount of the reserve established under this subsection without
          the prior written consent of all of the Lenders.

     (b)  Section 2.11(b) of the Loan Agreement hereby is amended and restated
in its entirety to read as follows:

               (b)  Supplemental Origination Fee. A one-time supplemental
          origination fee in the amount of $200,000, such fee to be fully earned
          on the Effective Date and due and payable on the first anniversary of
          the Effective Date or such earlier date (if any) on which this
          Agreement is terminated; provided, however, if all of the Obligations
          owing to Goldman Sachs Credit Partners L.P., a Bermuda limited


                                      -1-

<PAGE>   2

          partnership ("Goldman"), have been paid in full, in cash, on or prior
          to March 31, 1999, and all of the Commitments of Goldman are
          terminated on or prior to March 31, 1999, then, in connection
          therewith, Goldman hereby agrees to waive Goldman's Pro-Rata Share of
          the supplemental origination fee.

     (c)  Section 3.6 of the Loan Agreement is hereby amended and restated in
its entirety to read as follows:

               3.6  EARLY TERMINATION BY BORROWER. Borrower has the option, at
          any time upon 5 days prior written notice to Agent to terminate this
          Agreement by paying to Agent, for the ratable benefit of the Lender
          Group, in cash, the Obligations, in full, together with a premium (the
          "Early Termination Premium") equal to $250,000; provided, however, if
          the Obligations owing to Goldman have been paid in full, in cash, on
          or prior to March 31, 1999, and all of the Commitments of Goldman are
          terminated on or prior to March 31, 1999, then, in connection
          therewith, Goldman hereby agrees to waive Goldman's Pro-Rata Share of
          the Early Termination Premium and surrender Goldman's Warrant to
          Borrower.

3.   WAIVERS OF EXISTING EVENTS OF DEFAULT. Upon the effectiveness of this
Amendment, Lender hereby waives each of the Events of Default existing as of the
date of this Amendment and identified on Schedule A attached to this Amendment
(each, a "Specified Event of Default"). Such waiver is specific in time and in
intent and does not constitute, nor should it be construed as constituting,
except to the extent expressly set forth herein, a waiver or modification of any
term of, or right, power, or privilege under, the Loan Agreement, the other Loan
Documents, or any agreement, contract, indenture, document, or instrument
mentioned therein. Such waiver does not preclude any exercise of any right,
power, or privilege under any Loan Document, based upon any Event of Default
other than the Specified Events of Default.

4.   CONDITION PRECEDENTS TO AMENDMENT. The satisfaction of each of the
following unless waived or deferred by Agent in its sole discretion, shall
constitute conditions precedent to the effectiveness of this Amendment and each
and every provision hereof:

     (a)  The representations and warranties in the Loan Agreement as amended by
this Amendment, and the other Loan Documents shall be true and correct in all
respects on and as of the date hereof, as though made on such date (except to
the extent that such representations and warranties relate solely to an earlier
date).

     (b)  No injunction, writ, restraining order, or other order of any nature
prohibiting, directly or indirectly, the consummation of the transactions
contemplated herein shall have been issued and remain in force by any
governmental authority against the Agent or Lenders.

     (c)  Agent shall have received fully executed counterpart signatures to
this Amendment.


                                      -2-

<PAGE>   3

     (d)  Agent shall have received fully executed counterpart signatures to
that certain Amendment Number Two to Put Agreement, dated as of the date hereof,

identified on Schedule 1 thereto and Goldman Sachs Credit Partners, L.P., a
Bermuda limited partnership.

     (e)  Agent shall have received fully executed counterpart signatures to
that certain Amendment Number Two to Put Agreement, dated as of the date hereof,

Delaware corporation.

5.   CONSTRUCTION. This Amendment shall be governed by and construed in
accordance with the laws of the State of New York without giving effect to its
conflicts-of-laws principles (other than any provisions thereof validating the
choice of the laws of the State of New York as the governing law).

6.   ENTIRE AMENDMENT. This Amendment, and terms and provisions hereof,
constitute the entire agreement among the parties pertaining to the subject
matter hereof and supersedes any and all prior or contemporaneous amendments
relating to the subject matter hereof. Except as expressly amended hereby, the
Loan Agreement and other Loan Documents shall remain unchanged and in full force
and effect. To the extent any terms or provisions of this Amendment conflict
with those of the Loan Agreement or other Loan Document, the terms and
provisions of this Amendment shall control. This Amendment shall be deemed part
of and is hereby incorporated into the Loan Agreement.

7.   COUNTERPARTS; TELEFACSIMILE EXECUTION. This Amendment may be executed in
any number of counterparts, all of which taken together shall constitute one and
the same instrument and any of the parties hereto may execute this Amendment by
signing any such counterpart. Delivery of an executed counterpart of this
Amendment by telefacsimile shall be equally as effective as delivery of an
original executed counterpart of this Amendment. Any party delivering an
executed counterpart of this Amendment by telefacsimile also shall deliver an
original executed counterpart of this Amendment, but the failure to deliver an
original executed counterpart shall not affect the validity, enforceability, and
binding effect of this Amendment.

8.   AMENDMENTS. This Amendment cannot be altered, amended, changed or modified
in any respect or particular unless each such alteration, amendment, change or
modification shall have been agreed to by each of the parties and reduced to
writing in its entirety and signed and delivered by each party.

9.   MISCELLANEOUS. (a) Upon the effectiveness of this Amendment, each reference
in the Loan Agreement to "this Agreement", "hereunder", "herein", "hereof" or
words of like import referring to the Loan Agreement shall mean and refer to the
Loan Agreement as amended by this Amendment.

          Tranche A Advances plus the aggregate undrawn amount of all
          outstanding Letters of Credit to exceed the lesser of the Borrowing
          Base and the Maximum Tranche A Amount or (ii) the aggregate

          (b) Unless otherwise previously agreed in writing by the Borrower and
          the Agent, the initial term of (i) any documentary Letter of Credit
          shall not exceed one hundred twenty (120) days from the date of
          issuance and (ii) any standby Letter of Credit shall not exceed one
          calendar year from the date of issuance, subject to automatic renewal
          unless notice to the contrary is given by the Agent or the Issuing
          Bank in writing by the applicable date specified in such Letter of
          Credit. Each Letter of Credit shall state that, except as otherwise
          provided therein, such Letter of Credit is governed by the Uniform
          Customs and Practice for Documentary Credits (as most recently
          published by the International Chamber of Commerce). Notwithstanding
          the purpose of any Letter of Credit or any reference therein or herein
          to a Subsidiary or Affiliate of the Borrower, each Letter of Credit
          shall be deemed issued for the account of the Borrower and the
          obligations arising in connection therewith shall be part of the
          Obligations.

          (c) Immediately upon issuance or amendment of any Letter of Credit in
          accordance with the procedures set forth in this Section 2.13, each
          Lender shall be deemed to have irrevocably and unconditionally
          purchased and received from the Agent, without recourse or warranty,
          an undivided interest and participation, to the extent of such
          Lender's Pro Rata Share, of the liability and obligations under and
          with respect to such Letter of Credit and the Letter of Credit
          Agreement (including, without limitation, all obligations of the
          Borrower with respect thereto) and any security therefor or guaranty
          pertaining thereto.

          (d) Whenever the Borrower desires the issuance of a Letter of Credit,
          the Borrower shall deliver to the Agent a written irrevocable request
          no later than 10:00 a.m. (California time) at least five (5) Business
          Days (or such shorter period as may be agreed to by the Agent) in
          advance of the proposed date of issuance. The transmittal by the
          Borrower of each such request shall be deemed to be a representation
          and warranty by the Borrower that the Letter of Credit may be issued
          in accordance with and will not violate any of the requirements of
          this Section 2.13. Prior to the date of issuance of each Letter of
          Credit, the Borrower shall provide to the Agent a precise


                                      -6-


<PAGE>   17

          description of the documents and the text of any certificate to be
          presented by the beneficiary of such Letter of Credit which, if
          presented by such beneficiary on or prior to the expiration date of
          such Letter of Credit, would require the Issuing Bank to make payment
          under such Letter of Credit. The Agent, in its reasonable judgment,
          may require changes in any such documents and certificates prior to
          the date of issuance of any such Letter of Credit. No Letter of Credit
          shall require payment against a conforming draft to be made thereunder
          prior to the second Business Day after the date on which such draft is
          presented.

          (e) In the event of any request for drawing under any Letter of
          Credit, (i) the Borrower shall be deemed to have timely given a
          borrowing request to the Agent to make Tranche A Advances on the date
          on which such drawing is honored in an amount equal to the amount of
          such drawing and (ii) without regard to satisfaction of the applicable
          conditions specified in Article 3 and the other terms and conditions
          of borrowings contained herein, the Lenders shall, on the date of such
          drawing, make Tranche A Advances in the amount of such drawing, the
          proceeds of which shall be applied directly by the Agent to reimburse
          the Issuing Bank for the amount of such drawing or payment. If for any
          reason, proceeds of Tranche A Advances are not received by the Agent
          on such date in an amount equal to the amount of such drawing, the
          Borrower shall reimburse the Agent, on the Business Day immediately
          following the date of such drawing, in an amount in same day funds
          equal to the excess of the amount of such drawing over the amount of
          such Advances, if any, which are so received, plus accrued interest on
          such amount at the rate applicable to Tranche A Advances.

          (f) As among the Borrower, the Agent and each Lender, the Borrower
          assumes all risks of the acts and omissions of the Agent and the
          Issuing Bank or misuse of the Letters of Credit by the respective
          beneficiaries of such Letters of Credit other than the gross
          negligence or willful misconduct of the Agent or the Issuing Bank as
          determined by a court of competent jurisdiction in a final
          nonappealable judgment. In furtherance and not in limitation of the
          foregoing, neither the Agent nor any of the Lenders shall be
          responsible (i) for the form, validity, sufficiency, accuracy,
          genuineness or


                                      -7-

<PAGE>   18

          legal effects of any document submitted by any party in connection
          with the application for and issuance of or any drawing honored under
          such Letters of Credit even if it should in fact prove to be in any or
          all respects invalid, insufficient, inaccurate, fraudulent or forged,
          (ii) for the validity or sufficiency of any instrument transferring or
          assigning or purporting to transfer or assign any such Letter of
          Credit, or the rights or benefits thereunder or proceeds thereof, in
          whole or in part, which may prove to be invalid or ineffective for any
          reason, (iii) for failure of the beneficiary of any such Letter of
          Credit to comply fully with conditions required in order to draw upon
          such Letter of Credit, (iv) for errors, omissions, interruptions or
          delays in transmission or delivery of any messages, by mail, cable,
          telegraph, telex, telecopy or otherwise, whether or not they be in
          cipher, (v) for errors in interpretation of technical terms, (vi) for
          any loss or delay in the transmission or otherwise of any document
          required in order to make a drawing under any such Letter of Credit,
          or of the proceeds thereof, (vii) for the misapplication by the
          beneficiary of any such Letter of Credit of the proceeds of any
          drawing honored under such Letter of Credit, and (viii) for any
          consequences arising from causes beyond the control of the Issuing
          Bank, the Agent or the Lenders. None of the above shall affect,
          impair, or prevent the vesting of any of the Agent's rights or powers
          hereunder. Any action taken or omitted to be taken by the Agent under
          or in connection with any Letter of Credit, if taken or omitted in the
          absence of gross negligence or willful misconduct, shall not create
          any liability of the Agent to the Borrower or any Lender.

          (g) The obligations of the Borrower to reimburse the Agent for
          drawings honored under the Letters of Credit and the obligations of
          the Lenders under this Section 2.13 shall be unconditional and
          irrevocable and shall be paid strictly in accordance with the terms of
          this Agreement under all circumstances including, without limitation,
          the following circumstances: (i) any lack of validity or
          enforceability of this Agreement, any Letter of Credit, any Letter of
          Credit Agreement or any other agreement or instrument relating
          thereto; (ii) the existence of any claim, setoff, defense or other
          right which the Borrower or any Affiliate of the Borrower may have at
          any time


                                      -8-

          any Persons or entities for whom any such beneficiary or transferee
          may be acting), the Agent, any Lender or any other Person, whether in
          connection with this Agreement, the other Loan Documents, the
          transactions contemplated herein or therein or any unrelated
          transaction; (iii) any draft, demand, certificate or other documents
          presented under any Letter of Credit proving to be forged, fraudulent,
          invalid or insufficient in any respect or any statement therein being
          untrue or inaccurate in any respect; (iv) the surrender or impairment
          of any security for the performance or observance of any of the terms
          of any of the Loan Documents; (v) payment by the Issuing Bank under
          any Letter of Credit against presentation of a demand, draft or
          certificate or other document which does not comply with the terms of
          such Letter of Credit; (vi) failure of any drawing under a Letter of
          Credit or any non-application or misapplication by the beneficiary of
          the proceeds of any drawing; or (vii) the fact that a Potential

together with TBCC, the "Lenders") and TBCC, as agent (in such capacity, the
"Agent") for the Lenders, is made as of September 30, 1999 among the Borrower,
the Lenders and the Agent.


                              W I T N E S S E T H :


     WHEREAS, the Borrower, TBCC and the Agent are parties to the Loan and
Security Agreement, dated as of June 5, 1998 (as heretofore amended, the "Loan
Agreement"; capitalized terms used herein shall have the meanings assigned to
such terms in the Loan Agreement unless otherwise defined herein); and

     WHEREAS, the parties hereto wish to amend the Loan Agreement to, among
other things, increase the maximum amount of the credit facility and include PNC
as a Lender under the Loan Agreement and the other Loan Documents.

     NOW, THEREFORE, in consideration of the foregoing and for other good and
valuable consideration, the parties hereto hereby agree as follows:

     1.   AMENDMENTS TO LOAN AGREEMENT. Effective as of the date hereof, and
subject to the satisfaction of the conditions to effectiveness set forth in
Section 3 hereof, the Loan Agreement is hereby amended as follows:

          (a)  The definition of "Maximum Amount" in Section 1.1 is amended and
restated as follows:

          "'Maximum Amount' means $25,000,000."

          (b)  The definition of "Maximum Tranche A Amount" in Section 1.1 is
amended and restated as follows:

          "'Maximum Tranche A Amount' means $25,000,000."

<PAGE>   29

          (d)  Section 1.1 is amended by adding the following definitions in
their proper alphabetical order:

          "'Eligible Equipment' means the Equipment of the Borrower located in
          the United States, which is free from any claim of title or Lien in
          favor of any Person (other than Liens in favor of the Agent) and with
          respect to which no event has occurred and no condition exists which
          could be reasonably expected to impair substantially the Borrower's
          ability to use such Equipment in the ordinary course of its business
          and which the Agent, in good faith, shall deem eligible to serve as
          collateral for Advances. No Equipment of the Borrower shall be
          Eligible Equipment unless the Agent has a perfected first priority
          Lien thereon. No Equipment of the Borrower shall be Eligible Equipment
          unless (i) it is located on property owned by the Borrower or (ii) it
          is located on property leased by the Borrower or in a contract
          warehouse which is subject to a Collateral Access Agreement executed
          by the mortgagee, lessor or contract warehouseman, as the case may be,
          and segregated or otherwise separately identifiable from goods of
          others, if any, stored on the premises."

          "'Orderly Liquidation Value of Equipment' means the orderly
          liquidation value of Eligible Equipment as determined from time to
          time by an appraiser selected by the Agent. The Orderly Liquidation
          Value of Equipment is equal to $624,120 on September 30, 1999, as such
          amount may be adjusted from time to time pursuant to Section 4.6."

          (e)  Section 2.1(a) is amended by deleting the phrase "80% of Eligible
Accounts (net of the Foreign Accounts Reserve), less the amount, if any, of the
Dilution Reserve" and substituting therefor "an amount equal to the sum of (i)
85% of Eligible Accounts (net of the Foreign Accounts Reserve), less the amount,
if any, of the Dilution Reserve plus (ii) 75% of the Orderly Liquidation Value
of Eligible Equipment."

          (f)  Section 2.6(a) is amended and restated as follows:

          "(a) Interest Rate. Except as provided in clause (c) below, all
          Obligations shall bear interest at a per annum rate of 2 percentage
          points above the Reference Rate."

          during the period commencing on July 1, 1999 and ending on the earlier
          to occur of June 30, 2000"; and

               (iii) by deleting "(z) during the period commencing on the first
          anniversary of the Effective Date and ending on the earlier to occur
          of the second anniversary of the Effective Date" and substituting
          therefor "(z) during the period commencing on July 1, 2000 and ending
          on the earlier to occur of June 30, 2001."

          (h)  Section 3.4 of the Loan Agreement is hereby amended by deleting
"June 5, 2000" and substituting therefor "July 2, 2001."
