INTRODUCTORY NOTE

        This Annual Report on Form 10-K contains certain forward-looking
statements within the meaning of Section 27A of the Securities Act of 1933, as
amended, and Section 21E of the Securities Exchange Act of 1934, as amended, and
the Company intends that such forward-looking statements are subject to the safe
harbors created thereby. These forward-looking statements include (i) the
existence and development of the Company's technical and manufacturing
capabilities, (ii) anticipated competition, (iii) potential future growth in
revenues and income, (iv) potential future decreases in costs, and (v) the need
for, and availability of, additional financing. For this purpose, any statements
contained in this Annual Report on Form 10-K except for historical information
may be deemed to be forward-looking statements. Without limiting the generality
of the foregoing, words such as "may", "will", "expect", "believe",
"anticipate", "intend", "could", "estimate" or "continue", or the negative or
other variations thereof, or comparable terminology are intended to identify
forward-looking statements.

        The forward-looking statements included herein are based on current
expectations that involve a number of risks and uncertainties. These
forward-looking statements are based on assumptions, regarding the Company's
business, which involve judgments with respect to, among other things, future
economic, competitive and market conditions, and future business decisions, all
of which are difficult or impossible to predict accurately and many of which are
beyond the control of the Company. Although the Company believes that the
assumptions underlying the forward-looking statements are reasonable, any of the
assumptions could prove inaccurate and, therefore, there can be no assurance
that the results contemplated in forward-looking statements will be realized. In
addition, the business and operations of the Company are subject to substantial
risks which increase the uncertainty inherent in such forward-looking statements
(see "ADDITIONAL FACTORS THAT MAY AFFECT FUTURE OPERATING RESULTS AND THE MARKET
PRICE OF OUR STOCK" in Item 1 and "ITEM 7. MANAGEMENTS DISCUSSION AND ANALYSIS
OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS"). In light of the significant
uncertainties inherent in the forward-looking information included herein, the
inclusion of such information should not be regarded as a representation by the
Company or any other person that the objectives or plans of the Company will be
achieved or that expectations will be realized.

ITEM 1. BUSINESS.

GENERAL

        DISC, Inc. ("DISC" or the "Company") was incorporated under the laws of
the State of California in 1986. The Company operates in one business segment,
the computer mass storage system business. The Company designs, manufactures,
and markets a family of high-end computer mass storage systems which use 5.25
inch rewritable, magneto optical disks (MO) and CD-ROM disks. The Company
believes it is the only supplier of information storage products currently
offering a range of storage capacities up to 5.2 terabytes in the 5.25 inch
optical disk libraries and up to 1,470 CD-ROM platters.

PRODUCTS

        The Company's products consist of a family of optical disk storage
libraries based on 5.25 inch magneto optical or CD media. Their capabilities
cover the spectrum of high performance, transaction-oriented information systems
such as archival storage, imaging, network file servers and video/multimedia
servers.

        DISC's modular automated library design houses a combination of optical
disks, disk drives and an advanced robotic picking mechanism. Each library
contains an array of cubes, each of which can hold either a group of disks or
one to two optical disk drives. The modular design of DISC's libraries allows
users to choose the configuration which best suits their needs. By adding more
cells of either optical disks or drives, users can easily expand the system as
storage requirements grow. The modular design of the system also caters to
various types of drives or media, allowing users the opportunity to easily
upgrade their systems as higher performance drives and media are introduced.
Software, developed by and proprietary to the Company, allows a user's computer
to communicate with the DISC library and command a high performance robotic
device to select a desired disk from the array and insert it into a drive. Once
in the drive, the information access time for optical disks is approaching that
of magnetic disks.


                                       3
<PAGE>   4

The Company is currently shipping four different sizes of frames for the arrays,
to allow for different sized applications in the user's operation. The 5.25 inch
optical disk libraries range from 130 to over 1,050 magneto optical disks stored
and up to 32 optical drives. The CD-ROM libraries range in capacity from 300 CDs
to 1,400 CDs and can handle up to 48 CD-ROM readers. As of December 31, 1999
list prices for the Company's products range from approximately $40,000 to
$140,000, not including the costs of media.

        All of the Company's products have been designed to meet high duty
cycles while achieving high levels of reliability and ease of serviceability.

MARKETING AND SALES

        Applications for the Company's products include federal and local
government and military applications and insurance, banking, legal, multimedia
and medical applications on a worldwide basis. Sales of the Company's initial
product line commenced in 1991 and have been primarily to distributors, value
added resellers (VARs), original equipment manufacturers (OEMs) and system
integrators (SIs), who combine DISC libraries with software and/or other
products and resell the combination to the end-user or other members of the
supply channel.

        The Company's products are installed and serviced by an international
network of maintenance technicians from Bell and Howell and Anacomp Inc.
Technical assistance and second level support is provided by the Company's
support staff located in Milpitas, California.

        The Company's sales offices are located in Milpitas, California; Boston,
Massachusetts; Washington, District of Columbia; and Chicago, Illinois. The
Company's sales staff currently consists of five professional salespersons. In
addition, the Company has an independent sales representative located in
Crowborough, East Sussex, England.

        The Company's quarterly revenue and operating results have been affected
by seasonal trends. These trends often result in lower revenue in the first
quarter of each fiscal year compared to the fourth quarter of the previous
fiscal year due to customer purchasing and budgetary practices.

COMPETITION

        The computer information storage industry is highly competitive and
price erosion is typical over the life of a product. The Company's products
compete directly with other data storage products, including optical media,
magnetic tape cartridges and magnetic disk subsystems. The Company's competitors
include Hewlett-Packard Co., Storage Technology Corporation, Advanced Digital
Information Corporation and Plasmon. Other companies, including computer
manufacturers and other peripheral manufacturers, could enter the market at any
time. Such competitors may compete with the Company's products with lower prices
for similar products or by introducing new products that provide greater
storage capacity, faster access time or other improved features, any of which
could reduce demand for the Company's products or require the Company to reduce
its prices. Such competition could have a materially adverse effect on the
Company's results of operations. Many of the Company's competitors have
significantly greater financial, technical, manufacturing and marketing
resources than the Company, as well as significant market shares and installed
customer bases in certain market areas addressed by the Company. As a result,
the Company may not have the ability to keep pace with rapid competitive
developments and technological advances to the same extent as its competitors.

        However, the Company maintains an active program of research and
development in an effort to keep pace with potential competition and the Company
has close relationships with companies developing new high density optical
storage technologies.

        The principal market requirements for the Company's products are large
storage capacity, high recording speeds, reliability, compact physical size and
low cost per megabyte of storage. While desired capabilities generally vary by
product family and end user application, the Company believes that, because of
its modular design, easy scalability, high performance and reliability, DISC
products will compete favorably with respect to the requirements of the
secondary mass data storage market.

        Further discussion relating to the competitive conditions in the
computer mass storage system industry and the Company's competitive position in
the marketplace may be found in "ADDITIONAL FACTORS THAT MAY AFFECT FUTURE
OPERATING RESULTS AND THE MARKET PRICE OF OUR STOCK" under the heading
"COMPETITION IN THE COMPUTER INFORMATION STORAGE MARKET MAY LEAD TO REDUCED
MARKET SHARE, DECLINING PRICES AND REDUCED PROFITS".

MANUFACTURING AND COMPONENTS

        The Company's manufacturing operations consist of final system assembly
and product test activities. The majority of the parts and subassemblies in the
DISC libraries are standard, off-the-shelf components or are fabricated to
DISC's manufacturing documentation. These include power supplies, castings,
motors, bearings, timing belts and electronic components. The Company's
proprietary components, such as the frame, backplate, printed circuit assemblies
and other machined and fabricated parts are subcontracted out to independent
vendors.

        Certain components used by the Company are purchased from a single
source of supply. Where it relies on single sources of supply, the Company
generally has been able to obtain supplies of these components in a timely
manner and maintains an adequate inventory of components to meet its needs. The
Company believes alternative supplies for several components are available on
reasonable terms. However, failure of sources of supply and the inability of the
Company to develop alternative sources of supply as required in the future could
have a material adverse effect on the Company's operations.

RESEARCH AND DEVELOPMENT

        The Company has an active program of research and development consisting
of nine full-time employees in the areas of mechanical and electrical
engineering and software design. The Company's research and development
activities include robotics design and mass storage drive and technology design
and development. The Company expended $1,111,000, $1,290,000 and $1,439,000 on
research and development for the years ended December 31, 1999, 1998 and 1997,
respectively. The Company has completed its major development efforts with
respect to its 5.25 inch optical and CD products. The Company intends to
continue to expand its research and development activities in order to conduct
on-going development of existing products and to develop new products similar to
its current products.

BACKLOG

        The Company's backlog at December 31, 1999 was approximately $75,000 as
compared to a backlog of approximately $300,000 at December 31, 1998. The
Company includes in backlog only orders for products which are believed to be
firm and which are due to be shipped within 12 months. The Company includes in
backlog orders that may be canceled by customers upon payment of cancellation
charges which vary depending on the scheduled shipment date of the order.
Because of the possibility of customer changes in delivery schedules or
cancellation of orders, the Company's backlog as of any particular date may not
be indicative of actual revenues for any specific future period. Although the
Company has never experienced material cancellation problems, no assurance can
be given that the Company will continue to avoid cancellation problems in the
future.

PATENTS AND OTHER INTELLECTUAL PROPERTY

        The Company has received U.S. patents covering various aspects of its
technology, including the overall system design of its products. There can be no
assurance that any subsequent patent applications will be granted. The Company
believes that ownership of such patents is an important factor in its business
and its success does depend in part on the ownership thereof. However, the
Company believes that the improvement of its existing products, reliance upon
trade secrets and copyrights and on unpatented proprietary know-how and
innovation in the development of new products are generally as important as
patent protection in establishing and maintaining the Company's technological
advantage. The Company believes that the value of its products is partly
dependent upon its confidentiality and invention assignment agreements with its
employees. While the Company believes that patent, copyright and trade secret
laws should afford adequate protection of its proprietary technology, there can
be no assurance that the Company's proprietary technology will remain a trade
secret or that others will not develop a similar technology and use such a
technology to compete with the Company. Such competition could have a material
adverse effect on the Company. In addition, policing unauthorized use of the
Company's technology, particularly in foreign countries, may be difficult. The
Company has not received claims from third parties alleging


                                       5
<PAGE>   6

that the Company's products infringe the proprietary rights of third parties or
seeking indemnification against such infringements and knows of no basis for any
such claims. However, there can be no assurance that such claims will not be
made in the future. Such claims, if asserted, may involve costly and protracted
litigation and the Company may be required to license proprietary rights from
third parties. There can be no assurance that the Company would be able to
obtain licenses from third parties on commercially reasonable terms.

ENVIRONMENTAL LAWS

        Compliance with U.S. federal, state and local laws enacted for the
protection of the environment has to date had no material effect upon the
Company's capital expenditures, earnings or competitive position. Although the
Company does not anticipate any material adverse effects in the future based on
the nature of its operations and the thrust of such laws, no assurance can be
given that such laws, or any future laws enacted for the protection of the
environment, will not have a material adverse effect on the Company.

EMPLOYEES

        As of February 15, 2000, the Company employed 53 people on a full-time
basis, including 7 employees in administration and accounting, 8 employees in
marketing and sales, 9 employees in engineering, 20 employees in manufacturing,
3 employees in quality assurance and 6 employees in customer support. The
Company's future success is dependent, in part, on its continued ability to
attract, retain and motivate highly skilled personnel. The Company believes that
its relations with all employees are satisfactory. None of the employees are
covered by a collective bargaining agreement.

OTHER MATTERS

        Commvault Systems Inc. accounted for 23% of the Company's total revenue
in 1999. No single customer accounted for 10% or more of the Company's total
revenue in 1998 or 1997.

        No material portion of the Company's business is subject to
renegotiation of profits or contract termination at the election of the United
States government.

ADDITIONAL FACTORS THAT MAY AFFECT FUTURE OPERATING RESULTS AND THE MARKET PRICE
OF OUR STOCK

        The Company's future operating results, and stock price, may be affected
by a number of factors, many of which are beyond the Company's control. These
factors include the following:

        OUR QUARTERLY REVENUES AND OPERATING RESULTS MAY FLUCTUATE FOR A NUMBER
OF REASONS, WHICH MAY CAUSE OUR STOCK PRICE TO FLUCTUATE. Our quarterly
operating results have varied in the past and are likely to vary significantly
in the future due to several factors, including:

- - the size and timing of significant customer orders;

- - shifts in product or distribution channel mix;

- - increased competition and pricing pressure;

- - timing of new product announcements and releases by us or our competitors;

- - new product developments by storage device manufacturers;

- - the rate of growth in the data storage market;

- - market acceptance of new and enhanced versions of our products;

- - timing and levels of our operating expenses;

- - gain or loss of significant customers or distributors; and

- - personnel changes

        Our quarterly revenue and operating results have been affected by
seasonal trends. These trends often result in lower revenue in the first quarter
of each fiscal year compared to the fourth quarter of the previous fiscal year
due to customer purchasing and budgetary practices.


                                       6
<PAGE>   7

        Operating results in any period should not be considered indicative of
the results investors can expect for any future period. We cannot assure you
that we will be able to increase or even sustain our recent levels of quarterly
revenue and net sales, as normalized for unusual or one-time items, or that we
will attain or maintain profitability in any future period. Any unfavorable
change in the factors described above or any other factors could adversely
affect our operating results for a particular quarter. In addition, it is likely
that in some future quarters our operating results will be below the
expectations of public market analysts and investors. In any of these events,
the price of our common stock would likely decline.


        OUR STOCK PRICE MAY BE EXTREMELY VOLATILE. The market price of our
common stock has experienced fluctuations and is likely to fluctuate
significantly in the future. Our stock price can fluctuate for a number of
reasons, including:

- - announcements about us or our competitors;

- - quarterly variations in operating results;

- - the introduction of new technologies or products;

- - changes in product pricing policies by us or our competitors;

- - comments regarding us and the data storage market made on Internet bulletin
  boards; and

- - changes in earnings estimates by analysts or changes in accounting policies.

In addition, stock markets have experienced extreme price and volume volatility
in recent years. This volatility has had a substantial effect on the market
prices of securities of many smaller public companies for reasons frequently
unrelated or disproportionate to the operating performance of the specific
companies. These broad market fluctuations may adversely affect the market price
of our common stock.

        IF OUR SECURITIES ARE DELISTED FROM NASDAQ, THE TRADING MARKET AND
PRICES OF OUR SECURITIES WOULD BE HARMED. The trading of our common stock on the
NASDAQ System is conditioned upon our meeting certain asset, revenues and stock
price tests. If we fail any of these tests, our common stock may be delisted
from trading on the NASDAQ System, which could materially adversely affect the
trading market and prices for those securities. In addition, low price stocks
are subject to additional risks including additional state regulatory
requirements and the potential loss of effective trading markets.

        COMPETITION IN THE COMPUTER INFORMATION STORAGE MARKET MAY LEAD TO
REDUCED MARKET SHARE, DECLINING PRICES AND REDUCED PROFITS. The markets for data
storage solutions are intensely competitive, fragmented and characterized by
rapidly changing technology and evolving standards. These conditions could
render our products less competitive or obsolete and could harm our business,
financial condition and ability to market our products. Some of our competitors
have significantly more financial, technical, manufacturing, marketing and other
resources than we have. As a result, our competitors may be able to respond more
quickly than we can to new or changing opportunities, technologies, standards or
customer requirements. Competitors may develop products and technologies that
are less expensive or technologically superior to our products. In addition, our
competitors may manufacture and market their products more successfully than we
do our products. Competition from computer companies and others diversifying
into the field is expected to increase as the market develops. We may face
substantial competition from new entrants in the industry and from established
and emerging companies in related industries. There is significant price
competition in the markets in which we compete, and we believe that pricing
pressures are likely to continue. Certain competitors may reduce prices in order
to preserve or gain market share. This pricing pressure could result in
significant price erosion, reduced gross profit margins and loss of market
share, any of which could negatively affect our business, financial condition
and operating results.

        THE STORAGE DEVICE MARKET IS CHARACTERIZED BY RAPID TECHNOLOGICAL
EVOLUTION, AND OUR SUCCESS DEPENDS ON OUR ABILITY TO DEVELOP NEW PRODUCTS. The
market for our products is characterized by rapidly changing technology and
evolving industry standards and is highly competitive with respect to timely
innovation. At this time, the data storage market is particularly subject to
change with the emergence of Fibre Channel protocol and new storage solutions
such as storage area networks, or SANs, and network attached storage, or NAS,
devices. The introduction of new products


                                       7
<PAGE>   8

embodying new or alternative technology or the emergence of new industry
standards could render our existing products obsolete or unmarketable. Our
future success will depend in part on our ability to anticipate changes in
technology, to gain access to such technology for incorporation into our
products and to develop new and enhanced products on a timely and cost-effective
basis. Risks inherent in the development and introduction of new products
include:

- - the difficulty in forecasting customer demand accurately;

- - the possibility that sales of new products may cannibalize sales of our
  current products;

- - delays in our initial shipments of new products;

- - competitors' responses to our introduction of new products; and

- - the desire by customers to evaluate new products for longer periods of time
  before making a purchase decision.

        In addition, we must be able to maintain the compatibility of our
products with significant future device technologies, and we must rely on
producers of new device technologies to achieve and sustain market acceptance of
those technologies. Development schedules for high-technology products are
subject to uncertainty, and we may not meet our product development schedules.
We have in the past experienced delays in the introduction of some new products.
If we are unable, for technological or other reasons, to develop products in a
timely manner or if the products or product enhancements that we develop do not
achieve market acceptance, our business will be harmed.

        WE HAVE A HISTORY OF LOSSES AND WE EXPECT TO INCUR FUTURE LOSSES. The
Company has experienced significant operating losses since its inception, and as
of December 31, 1999 had an accumulated deficit of $27,018,000. The Company
expects to continue to incur net losses for the foreseeable future, and the
Company's ability to sustain its operations for a significant period after
December 31, 2000 will depend on the Company's ability to significantly increase
sales or raise significant additional debt or equity financing. There can be no
assurance that the Company will be able to increase sales or that additional
financing will be available on acceptable terms, or at all.

        ANY INABILITY TO MEET OUR FUTURE CAPITAL REQUIREMENTS WOULD LIMIT OUR
ABILITY TO GROW. We may need, or could elect, to seek additional funding in the
future. In the event we need to raise additional funds, we may not be able to do
so on favorable terms, if at all. Further, if we issue equity securities,
shareholders may experience additional dilution or the new equity securities may
have rights, preferences or privileges senior to those of our existing
securities. If we cannot raise funds on acceptable terms, we may not be able to
develop or enhance our products, take advantage of future opportunities or
respond to competitive pressures or unanticipated requirements.

        CONCENTRATION OF OWNERSHIP AMONG OUR EXISTING EXECUTIVE OFFICERS,
DIRECTORS AND PRINCIPAL SHAREHOLDERS MAY PREVENT OTHER INVESTORS FROM
INFLUENCING SIGNIFICANT CORPORATE DECISIONS. As of March 15, 2000, our executive
officers, directors and principal shareholders will beneficially own, in the
aggregate, approximately 88% of our outstanding common stock and preferred
stock, on an as-if-converted basis. As a result, these shareholders, if acting
together, will be able to exercise control over all matters requiring
shareholder approval, including the election of directors and approval of
significant corporate transactions. This concentration of ownership could
disadvantage other shareholders with interests different from those of our
officers, directors and principal shareholders. For example, our officers,
directors and principal shareholders could delay or prevent an acquisition or
merger even if the transaction would benefit other shareholders.

        BECAUSE WE OPERATE WITH LITTLE BACKLOG, OUR OPERATING RESULTS COULD BE
ADVERSELY AFFECTED IF WE DO NOT ACCURATELY ANTICIPATE FUTURE SALES LEVELS.
Historically, we have operated with little order backlog and, due to the nature
of our business, do not anticipate that we will have significant backlog in the
future. Consequently, a large portion of our revenue in each quarter results
from orders placed during that quarter. Because of the relatively large dollar
size of orders from our distributors and customers, delay in the placing of a
small number of orders by a small number of purchasers could negatively affect
our operating results for a particular period. In addition, our operating
expense levels are, in the short term, largely fixed and are based, in part, on
expectations regarding future sales. Thus, our operating results could be
disproportionately affected if we do not receive the expected number of orders
in a given quarter and our net sales falls below our expectations.

        WE DEPEND ON CERTAIN KEY SUPPLIERS. We do not possess proprietary
optical disk, high-density disk or other storage technologies and, consequently,
we depend on a limited number of third-party manufacturers to supply us with the
devices that we incorporate into our products. In some cases, these
manufacturers are sole-source providers of the device technology. Our suppliers
have in the past been, and may in the future be, unable to meet our supply
needs, including our needs for timely delivery, adequate quantity and high
quality. We do not have long-term contracts with any of our significant
suppliers. If these suppliers were to decide to pursue the disc library market
directly, they may cease supplying us with disc drives and media, in which case
we may be unable to obtain adequate supplies of disc drives and media at
acceptable prices, if at all. The partial or complete loss of any of our
suppliers could result in significant lost sales, added costs and production
delays or may otherwise harm our business, financial condition, operating
results and customer relationships.

        WE HAVE A CONCENTRATED CUSTOMER BASE, AND THEREFORE THE LOSS OF A SINGLE
CUSTOMER COULD NEGATIVELY AFFECT OUR OPERATING RESULTS. The majority of our end
users purchase our products from distributors, value-added resellers, original
equipment manufacturers, and systems integrators. In fiscal 1999, Commvault
Systems Inc. accounted for 23% of our total revenue. We have no long-term orders
with any of our significant customers or distributors. Generally we sell
products pursuant to purchase orders. In addition, our distributors carry
competing product lines which they may promote over our products. A distributor
may not continue to purchase our products or market them effectively. Moreover,
certain of our contracts with our distributors contain "most favored nation"
pricing provisions which mandate that we offer our products to these customers
at the lowest price offered to other similarly situated customers. Our operating
results could be adversely affected if any of the following factors were to
occur relating to one or more of our significant resellers:

- - the reduction, delay or cancellation of orders or the return of a significant
  amount of products;

- - the loss of one or more of such resellers; or

- - any financial difficulties of those resellers that result in their inability
  to pay amounts owed to us.

        WE MAY BE SUED BY OUR CUSTOMERS FOR PRODUCT LIABILITY CLAIMS AS A RESULT
OF FAILURES IN OUR DATA STORAGE PRODUCTS. We face potential liability for
performance problems of our products because our end users employ our storage
technologies for the storage and backup of important data. Although we maintain
general liability insurance, our insurance may not cover potential claims of
this type or may not be adequate to indemnify us for all liability that may be
imposed. Any imposition of liability that is not covered by insurance or is in
excess of our insurance coverage could harm our business.

        A NUMBER OF KEY PERSONNEL ARE CRITICAL TO THE SUCCESS OF OUR BUSINESS.
Our future success depends in large part on our ability to retain certain key
executives and other personnel, some of whom have been instrumental in
establishing and maintaining strategic relationships with key suppliers and
customers. We do not have any employment agreements with our employees. Our
future growth and success will depend in large part on our ability to hire,
motivate and retain highly qualified management, technical, operations and sales
and marketing personnel. Competition for such personnel is intense in the
high-technology industry, particularly in the San Francisco Bay area. We may not
be able to retain our existing personnel or attract additional qualified
personnel in the future. In addition, companies in our industry whose employees
accept positions with competitors frequently claim that their competitors have
engaged in unfair hiring practices. We may receive such claims in the future as
we seek to hire qualified personnel, and such claims could result in litigation.
Regardless of the merits of these claims, we could incur substantial costs in
defending ourselves against these claims.

ITEM 2. PROPERTIES.

        The Company's executive offices and engineering/manufacturing operations
are located in approximately 17,000 square feet of space in Milpitas,
California. The Company leases the facility pursuant to a lease that will expire
on October 31, 2000. The Company believes that the lease can be renewed at
satisfactory terms and that this facility will be sufficient to support
operations for the foreseeable future. However, the Company believes that, if
necessary, additional space will be available in the area to house the Company's
operations.

        The closing price of the Company's common stock on March 24, 2000, as
reported by the NASDAQ Small Cap Market System was $6.50. As of March 24, 2000,
according to the records of the Company's transfer agent, the Company had
approximately 50 shareholders of record. Because many of the Company's shares
are held by brokers and other institutions on behalf of stockholders, the number
of record holders is not necessarily indicative of the total number of
stockholders. As of June 28, 1999 (the record date for the 1999 annual meeting
of the Company), the Company had over 500 shareholders, and the Company believes
that it presently has over 400 shareholders. The Company has never paid cash
dividends and has no present plans to pay dividends. See "LIQUIDITY AND CAPITAL
RESOURCES" in "ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
CONDITION AND RESULTS OF OPERATIONS" and Note 5 of Notes to Financial Statements

and convertible debentures during the last fiscal year were deemed to be exempt
from registration under the Securities Act in reliance on Section 4(2) of the
Securities Act, or Regulation D promulgated thereunder, as transactions by an
issuer not involving a public offering. The recipients of securities in each
such transaction represented their intention to acquire the securities for
investment only and not with a view to or for sale in connection with any

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS.

        This section and other parts of this Annual Report on Form 10-K contain
forward looking statements within the meaning of Section 27A of the Securities
Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934,
as amended, and the Company intends that such forward-looking statements are
subject to the safe harbors created thereby. See "INTRODUCTORY NOTE" on page 3
hereof. Forward-looking statements involve risks and uncertainties, and the
Company's actual results may differ significantly from the results discussed in
the forward-looking statements. Factors that might cause such differences
include, but are not limited to, those discussed in the subsection entitled
"ADDITIONAL FACTORS THAT MAY AFFECT FUTURE OPERATING RESULTS AND THE MARKET
PRICE OF OUR STOCK" in Item 1 above and elsewhere in this Annual Report on Form
10-K. The following discussion should be read in conjunction with the financial
statements and notes thereto included in Item 8 of this Form 10-K. All
information is based on the Company's fiscal calendar.

RESULTS OF OPERATIONS

        NET SALES. The Company had net sales of $9,746,000 in 1999, $9,145,000
in 1998 and $8,655,000 in 1997. In 1999, the number of units sold was relatively
flat as customers deferred spending on new information storage systems while
they completed their year 2000 testing activities. The increase in net sales in
1999 was primarily due to the Company's renewed emphasis on selling media along
with the Company's products. Management believes that the increase in sales in
1998 as compared to 1997 was due to an expanded customer base resulting from an
increase in the Company's direct sales personnel. The general sales cycles for
distribution of the Company's products are similar to those of most businesses
selling products designed for use as part of large systems, and range from three
to six months for Value Added Resellers (VAR) and small System Integrators and
from one to two years for Original Equipment Manufacturers (OEM), Product
Integrators and large System Integrators.

        COST OF SALES. Cost of sales, as a percentage of sales, was
approximately 75% in 1999, 76% in 1998 and 77% in 1997. The Company's relatively
low gross margins reflect the Company's low sales volumes, which have resulted
in unabsorbed manufacturing costs and high costs of materials due to the
inability to achieve purchasing economies of scale due to low sales volume. The
Company expects that, as product sales continue to increase, costs of sales per
unit of product will decrease because fixed manufacturing costs will be
distributed over the larger sales volume, and material costs will decrease as
the result of volume purchases. In addition, in 1999 gross margin was impacted
by product mix and pricing discounts for a high volume customer.

        RESEARCH AND DEVELOPMENT EXPENSES. Research and development expenses
were $1,111,000 in 1999, $1,290,000 in 1998 and $1,439,000 in 1997. Expenses
decreased in 1999 as compared to 1998 primarily due to a reduction in headcount
due to attrition. The primary reason for the decrease in expenses in 1998 as
compared to 1997 were decreases in expenses related to the Orion project, which
was substantially complete by the end of the


                                       11
<PAGE>   12

second quarter of 1998. The Company believes that research and development
expenses will increase moderately in 2000 due to current projects under
development.

        MARKETING AND SALES EXPENSES. Marketing and sales expenses were
$2,169,000 in 1999, $2,011,000 in 1998 and $1,960,000 in 1997. Expenses
increased in 1999 as compared to 1998 primarily due to an increased
participation in industry trade shows. The primary reason for the increase from
1997 to 1998 was the expansion of the Company's direct sales personnel. The
Company believes that in 2000 marketing and sales expenses will increase in
connection with the Company's continued efforts to broaden market acceptance of
its products. In particular, the Company intends to increase its sales force and
increase its spending on market awareness activities.

        GENERAL AND ADMINISTRATIVE EXPENSES. General and administrative expenses
were $1,085,000 in 1999, $1,030,000 in 1998 and $924,000 in 1997. The increase
in expenses in 1998 as compared to 1997 was primarily due to a return to the
employee headcount level of fiscal 1996. The Company believes that general and
administrative expenses will be remain relatively flat during 2000.

LIQUIDITY AND CAPITAL RESOURCES

        During 1999, 1998 and 1997, the Company used $1,149,000, $2,816,000 and
$2,530,000, respectively, primarily to fund operating losses. In fiscal 1999,
the Company raised $2,075,000 through the issuance of convertible preferred
stocks. At December 31, 1999, the Company had a cash balance of approximately
$1,126,000. In addition, the Company has a commitment from its largest investor
to invest up to $2,000,000, if needed. The Company believes this committed
future investment, together with borrowing from a credit line with a financial
institution, which allows it to borrow the lesser of $2,000,000 or 80% of
eligible receivables (see Note 4 to the Notes to Financial Statements for a
further description of the credit line), and cash generated from operations,
will be sufficient to meet its operating requirements at least through the end
of 2000, although the Company anticipates that it will continue to incur net
losses for the foreseeable future. The ability to sustain its operations for a
significant period after December 31, 2000, will depend on the Company's ability
to significantly increase sales or raise significant additional equity or debt
financing on terms acceptable to the Company. There is no assurance that any of
these conditions will be achieved. In particular, the Company expects to require
increasing amounts of cash to finance the Company's efforts to increase sales,
which the Company plans to achieve by increasing selling efforts to large system
integrators and OEMs, by hiring additional sales and sales support staff and by
making evaluation units available. In addition, the Company intends to expand
its current network of resellers. The Company may require cash to finance
purchases of inventory to satisfy anticipated increased sales as the Company's
products achieve market acceptance.

        Although the Company has not committed to make any material capital
expenditures as of December 31, 1999, the budget for capital equipment
expenditures for 2000 is approximately $275,000. The majority of these purchases
are expected to be in the areas of process and molding tooling to reduce cost
and improve producibility of the Company's products.

        The terms of the Series C Preferred Stock and outstanding warrants may
limit the availability of financing for the Company, particularly equity
financing. Holders of Series C Preferred Stock are entitled to receive
cumulative dividends in the amount of approximately $112,000 per year. The
Company has never paid cash dividends and has no present plans to pay dividends.

IMPACT OF YEAR 2000

        To date, we have not experienced any material Year 2000 issues with our
products or our internal computer systems. We are also not aware of any material
year 2000 problems with our vendors, or distribution partners. Accordingly, we
do not anticipate incurring material expenses or experiencing any material
operational disruptions as a result of any Year 2000 problems.

requires the Company's officers and directors, and persons who own more than ten
percent of a registered class of the Company's equity securities, to file
reports of securities ownership and changes in such ownership with the
Securities and Exchange Commission (the "SEC"). Officers, directors and greater
than ten percent shareholders also are required by rules promulgated by the SEC
to furnish the Company with copies of all Section 16(a) forms they file.

        Based solely upon a review of the copies of such forms furnished to the
Company, the absence of a Form 3 or Form 5 or written representations that no
Forms 5 were required, the Company believes that, during fiscal year 1999, its
officers, directors and greater than ten percent beneficial owners complied with
all applicable Section 16(a) filing requirements.

Directors, each non-employee director receives an initial grant of options to

non-employee director is granted an option to purchase 5,000 shares of the
Company's Common Stock during each year of service as a director commencing with
fiscal year 1995.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

        Frank T. Connors, Michael A. McManus, Jr. and F. Rigdon Currie comprised
the Board's Compensation Committee during fiscal 1999. Mr. Connors has been
Secretary of the Company since May 1990 and was the Chief Executive Officer of
the Company from May 1990 to December 1994. Neither Mr. McManus nor Mr. Currie
was during fiscal 1999 an officer or employee of the Company, and neither has
been an officer or employee of the Company. Please see "ITEM 13. CERTAIN
RELATIONSHIPS AND RELATED TRANSACTIONS" for a discussion of certain
relationships and transactions between Mr. Currie and the Company. During fiscal
year 1999, no executive officer of the Company (i) served as a member of the
compensation committee (or other board committee performing equivalent functions
or, in the absence of any such committee, the board of directors) of another
entity, one of whose executive officers served on the Company's Compensation
Committee, (ii) served as a director of another entity, one of whose executive
officers served on the Company's Compensation Committee, or (iii) served as a
member of the compensation committee (or other board committee performing
equivalent functions or, in the absence of any such committee, the board of
directors) of another entity, one of whose executive officers served as a
director of the Company.

ITEM 12. SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT.

        The following table sets forth certain information regarding the
beneficial ownership of Common Stock of the Company as of March 15, 2000, as to
(a) all directors, (b) the named executive officers identified in the Summary
Compensation Table located in Item 11, (c) all directors and executive officers
as a group, and (d) each person known to the Company to be the beneficial owner
of more than 5% of any class of the Company's voting securities.

<PAGE>   16

Each share of the Company's Series C, Series D, Series E and Series I through
Series O Preferred Stock is convertible into one share of Common Stock and is
entitled to one vote per share. Each share of the Company's Series F Preferred
Stock is convertible into two shares of Common Stock and is entitled to two
votes per share. Each share of Series G, Series H and Series P through Series W
Preferred Stock is convertible into ten shares of Common Stock and is entitled
to ten votes per share. Because the Company's outstanding Preferred Stock votes
together with and has the same rights to cumulative voting as the Common Stock,
the number of shares held by each beneficial owner includes all shares of Common
Stock and Preferred Stock on an as-if-converted basis, and "Percentage of Class"
represents the total of the Company's Common and Preferred Stock, on an
as-if-converted basis, issued and outstanding as of March 15, 2000. Except as
otherwise indicated, the Company believes, based on information furnished by
such owners, that the beneficial owners of the Common Stock and Preferred Stock
have sole investment and voting power with respect to such shares, subject to
applicable community property laws.

DISC, INC.
NOTES TO FINANCIAL STATEMENTS

NOTE 1 - THE COMPANY:

DISC, INC. ("the Company") is engaged in the marketing, development and
manufacturing of optical disk storage units.

Subsequent to year end, the Company received a commitment from its largest
investor for additional equity financing of up to $2,000,000, if necessary,
through the issuance of Preferred Stock. The Company believes that this cash,
together with cash generated from operations, will be sufficient to meet its
operating requirements at least through the end of 2000, although the Company
anticipates that it will continue to incur net losses for the foreseeable
future. The ability to sustain its operations for a significant period after
December 31, 2000, will depend on the Company's ability to significantly
increase sales or raise significant additional equity or debt financing.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

USE OF ESTIMATES

The preparation of the financial statements in accordance with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosures of contingent assets and liabilities at the date of the financial
statements and reported amounts of revenue and expenses during the reporting
period. Actual results could differ from those estimates.

CERTAIN RISKS AND CONCENTRATIONS

At December 31, 1999, substantially all of the Company's cash and cash
equivalents were invested with one financial institution.

The Company performs ongoing credit evaluations of its customers' financial
condition and, generally requires no collateral from its customers. At December
31, 1999, two customers represented 29% and 11%, respectively, of the accounts
receivable balance. At December 31, 1998, no customer represented 10% or more of
the accounts receivable balance. At December 31, 1997, one customer represented
22% of the accounts receivable balance. The Company maintains an allowance for
doubtful accounts receivable based upon the collectibility of all accounts
receivable.

In 1999, one customer accounted for 23% of net sales. No customer accounted for
more than 10% of net sales in fiscal 1998 and 1997.

FINANCIAL INSTRUMENTS

The carrying amount of the Company's financial instruments, including cash and
equivalents, accounts receivable, accounts payable and accrued expenses
approximate fair value due to their short maturities.

CASH AND CASH EQUIVALENTS

The Company considers all highly liquid investments with maturities of three
months or less at the time of purchase and money market funds to be cash
equivalents.

REVENUE RECOGNITION

Revenue from product sales is recognized upon shipment of the product when the
Company has no significant obligations remaining and collection of the resulting
receivable is probable.

                                       27
<PAGE>   28

INVENTORIES

Inventories are stated at the lower of cost or market, with cost being
determined on a first-in, first-out method.

PROPERTY AND EQUIPMENT

Property and equipment are stated at cost. Depreciation is computed using the
straight line method over the shorter of the estimated useful lives of the
assets, which range from three to five years, or the lease term of the
respective assets, if applicable.

RESEARCH AND DEVELOPMENT

Research and development costs are charged to expense as incurred.

STOCK COMPENSATION PLANS

The Company accounts for stock-based compensation arrangements using the
intrinsic value method as prescribed in Accounting Principles Board Opinion No.
25, "Accounting for Stock Issued to Employees" ("APB 25") and related
Interpretations thereof. Compensation cost for stock grants is measured as the
excess, if any, of the market price of the Company's stock at the date of grant
over the stock exercise price. The Company's policy is to grant stock options
with an exercise price equal to the quoted market price of the Company's stock
on the date of grant. Accordingly, the Company does not have compensation cost
related to its stock compensation plans. In addition, the Company complies with
the disclosure provisions of Statement of Financial Accounting Standard No. 123,
"Accounting for Stock-Based Compensation" ("SFAS 123").

INCOME TAXES

The Company accounts for income taxes in accordance with Statement of Financial
Accounting Standard No. 109, "Accounting for Income Taxes" ("SFAS 109"). SFAS
109 accounts for income taxes under an asset and liability approach, which
requires the recognition of deferred tax liabilities and assets for the expected
future tax consequences of timing differences between the carrying amounts and
the tax bases of assets and liabilities. Valuation allowances are established
when necessary to reduce deferred tax assets to the amount expected to be
realized.

COMPREHENSIVE INCOME (LOSS)

For the three years in the period ended December 31, 1999, there were no
elements of comprehensive income (loss), except for the net losses.

RECENT ACCOUNTING PRONOUNCEMENTS

In June 1998, the FASB issued Statement of Financial Accounting Standards No.
133, Accounting for Derivative Instruments and Hedging Activities. SFAS 133
establishes new standards of accounting and reporting for derivative instruments
and hedging activities. SFAS 133 requires that all derivatives be recognized at
fair value in the statement of financial position, and that the corresponding
gains or losses be reported either in the statement of operations or as a
component of comprehensive income, depending on the type of hedging relationship
that exists. SFAS 133 will be effective for fiscal years beginning after June
15, 2000. The Company currently does not hold derivative instruments or engage
in hedging activities.

NOTE 4 - DEBT:

The Company has had a line of credit agreement with a financial institution
since 1994 and which was amended in December 1999 to extend the expiration date
to December 2000. This agreement requires the Company to comply with certain
financial convenants. Borrowings under this facility are limited to the lesser
of $2,000,000 or 80% of eligible receivables. At December 31, 1999 and 1998,
$1,165,000 and $1,632,000, respectively, were outstanding under the line.
Borrowings under this facility bear interest at the bank's prime rate plus 2%
(10.50% at December 31, 1999) with a minimum of 9% and are secured by
substantially all of the assets of the Company. In addition, the agreement
requires a minimum interest charge of $9,000 per month. At December 31, 1999,
the Company was in compliance with the covenants.

The holders of Series C Preferred Stock are entitled to receive $0.30 per share
per annum cumulative dividends prior to and in preference to Common
Shareholders. Such dividends are cumulative whether or not declared by the Board
of Directors. The holders of Series D through W Preferred Stock are entitled to
receive, when and if declared by the Board of Directors, dividends in the same
amount per share as declared on the Company's Common Stock, with each share of
Preferred Stock being treated for this purpose as the number of shares of Common
Stock into which it is then convertible.

Each share of Preferred Stock has the number of votes equal to the number of
shares of Common Stock into which it is then convertible. The Company has
reserved sufficient shares of Common Stock to allow for the conversion of all
outstanding Preferred Stock.

Shares of Series H through W Preferred Stock were issued pursuant to an
agreement entered into in March 1996, as amended, with the Company's largest
shareholder whereby the Company agreed to sell and the shareholder agreed to
purchase subordinated convertible debentures. The conversion price of the
debentures is 85% of the lower of the average closing price of the Company's
Common Stock for the five trading days ended three days prior to the end of the
quarter or the closing bid price on the last day of the quarter in which the
convertible debentures are issued.

The Company issued Warrants in conjunction with the issuance of Preferred Stock.
The Warrants entitle the holders to purchase the Company's Common Stock.

NOTE 6 - STOCK OPTION PLAN:

At December 31, 1999, the Company had two stock-based compensation plans, which
are described below:

THE 1990 PLAN

Under the 1990 Stock Option Plan, as amended in 1999 (the "1990 Plan"),
employees, consultants and non-employee directors (prior to 1995) may be granted
options for up to 1,350,000 shares of Common Stock which vest over a four year
period from the date of grant. The options vest equally on a monthly basis
unless it is the employee's or consultant's first stock grant, in which case
vesting commences six months from the date of grant.

At December 31, 1999, 254,000 shares were available for grant under the 1990
Plan.

On May 20, 1996, the Company canceled options to purchase 72,600 shares of
Common Stock with exercise prices ranging from $4.25 to $6.25, previously
granted to employees and reissued all such options at an exercise price of
$3.88, the fair market value of the stock on that date. The reissued options
vest over a four year period from the date of reissuance.

On May 19, 1998 the Company canceled options to purchase 952,850 shares of
Common Stock with exercise prices ranging from $1.03 to $6.38 previously granted
to employees. The Company reissued all such options at an exercise price of
$0.75, the fair market value of the stock on that date. The reissued options
vest over a four year period from the date of reissuance.

THE NON-EMPLOYEE OPTION PLAN

In 1995, the Board of Directors adopted and the shareholders approved the 1995
Stock Option Plan for Non-Employee Directors (the "Non-Employee Option Plan").
The Company has reserved 150,000 shares of Common Stock for issuance under this
Plan. Under the Non-Employee Option Plan, each newly-elected non-employee
director of the Company will be granted a non-statutory option to purchase
25,000 shares of the Company's


                                       31
<PAGE>   32

Common Stock. This option vests over a three year period. In addition,
commencing in 1995, each non-employee director of the Company will be granted a
non-statutory option to purchase 5,000 shares of the Company's Common Stock
during each year of service as a director of the Company. These options vest
immediately upon grant and are immediately exercisable.

At December 31, 1999, 25,000 shares were available for grant under the
Non-Employee Option Plan.

On May 19, 1998, the Company canceled options to purchase 75,000 shares of
Common Stock with exercise prices ranging from $1.16 to $6.38 previously granted
to the non-employee directors. The Company reissued all such options at an
exercise price of $0.75, the fair market value of the stock on that date. The
reissued options vest immediately.

Under both plans, the options will be granted at prices equal to the fair market
value on the date of grant and expire five years from the date of grant.

The following table summarizes the combined activity of the 1990 Plan and the
Non-Employee Option Plan for the years ended December 31, 1999, 1998 and 1997:

The Company applies APB 25 and related Interpretations in accounting for its
stock option plans. Since all of the Company's stock options were granted at
fair market value at the date of grant, no compensation cost has been recognized
for its fixed stock option plans. Had compensation cost for the Company's two
stock-based compensation plans been determined consistent with SFAS 123, the
Company's net loss and net loss per share would have been increased to the pro
forma amounts indicated below:

The compensation cost calculated under SFAS 123 is based on options granted from
1995 through 1999, and because additional option grants are expected to be made
each year, the above pro forma disclosures are not representative of the pro
forma effects of option grants on reported net income for future years.

The fair value of each option grant is estimated on the date of grant using the
Black-Scholes option-pricing model with the following weighted-average
assumptions used for grants in 1999, 1998, and 1997: expected volatility of
144.5% for 1999, 112.9% for 1998 and 76.7% for 1997; dividend yield of 0% for
all years; risk-free interest rates for the last day of the month in which the
options were granted; and expected lives of 4 years for the 1990 Option Plan and
5 years for the Non-Employee Option Plan.

NOTE 7 - INCOME TAXES:

No provisions for federal or state income taxes were recorded for the years
ended December 31, 1999, 1998 and 1997 as the Company incurred net operating
losses during these years.

Significant components of the Company's deferred tax assets are as follows:

</TABLE>

Management believes that it is more likely than not that the deferred tax assets
will not be utilized. Accordingly, a full valuation allowance has been recorded.

At December 31, 1999, the Company had approximately $25,171,000 of federal and
$8,072,000 of state net operating loss carryforwards available to offset future
taxable income which expire in varying amounts beginning in 2000. Under the Tax
Reform Act of 1986, the amounts of and benefits from net operating loss
carryforwards may be impaired or limited in certain circumstances. Events which
cause limitations in the amount of net operating losses that the Company may
utilize in any one year include, but are not limited to, a cumulative ownership
change of more than 50% as defined, over a three year period.

The benefit for income taxes differed from the amount determined by applying
U.S. statutory income tax rates to income before income taxes. A reconciliation

NOTE 8 - COMMITMENTS

The Company occupies its facility under a non-cancelable operating lease
agreement which expires on October 31, 2000. The lease requires the Company to
pay property taxes and insurance.

The total minimum lease payments under the lease at December 31, 1999, excluding
insurance, normal maintenance and certain property taxes, are $134,000.

Total rental expense under operating leases, including month-to-month rentals,
was $159,000, $181,000 and $183,000 for the years ended December 31, 1999, 1998
and 1997, respectively.

NOTE 9 - NET LOSS PER SHARE

Options and Warrants to purchase shares, and Convertible Preferred Stock
outstanding totaling 11,109,059 were not included in the computation of diluted
net loss per share, as their effect was antidilutive for the periods presented.
Therefore, both the basic and diluted net loss per share computations resulted
in the same number and there were no reconciling items.

NOTE 10 - OPERATING SEGMENTS

The Company has adopted SFAS No. 131, "Disclosures about Segments of an
Enterprise and Related Information." This statement requires enterprises to
report information about operating segments in annual financial statements and
selected information about reportable segments in interim financial reports. It
also establishes standards for related disclosures about products, geographic
areas and major customers. The Company operates in one industry segment.

Enterprise-wide information is provided in accordance with SFAS 131.

The Company sells its products predominately in the United States. No other
geographic region accounted for more than 10% of net sales in fiscal 1999, 1998,
or 1997.

The Company has no long-lived assets outside the United States in any of the
years presented.

REPORT OF INDEPENDENT ACCOUNTANTS

TO THE BOARD OF DIRECTORS AND SHAREHOLDERS OF DISC, INC.

In our opinion, the accompanying balance sheet and the related statements of
operations, of shareholders' equity and of cash flows present fairly, in all

                                       OF
                            SERIES T PREFERRED STOCK
                                       OF
                                   DISC, INC.


      We, J. Richard Ellis and Henry Madrid, hereby certify that we are the
President and the Chief Financial Officer, respectively, of DISC, INC., a
corporation organized and existing under the General Corporation Law of the
State of California, and further, DO HEREBY CERTIFY:

      That pursuant to the authority conferred upon the Board of Directors by
the Articles of Incorporation of the said Corporation, the said Board of
Directors on March 31, 1999 adopted the following resolution creating a series
of 16,089 shares of Preferred Stock designated as Series T Preferred Stock, none
of which shares have been issued:

            "RESOLVED, that pursuant to the authority vested in the Board of
      Directors of the corporation by the Articles of Incorporation, the Board
      of Directors does hereby provide for the issuance of a series of Preferred
      Stock, no par value, of the Corporation, to be designated "Series T
      Preferred Stock," initially consisting of 16,089 shares and to the extent
      that the designations, powers, preferences and relative and other special
      rights and the qualifications, limitations and restrictions of the Series
      T Preferred Stock are not stated and expressed in the Articles of
      Incorporation, does hereby fix and herein state and express such
      designations, powers, preferences and relative and other special rights
      and the qualifications, limitations and restrictions thereof, as follows
      (all terms used herein which are defined in the Articles of Incorporation
      shall be deemed to have the meanings provided therein):


<PAGE>   2


            Section 1. Designation and Amount. The shares of such series shall
      be designated as "Series T Preferred Stock," no par value, and the number
      of shares constituting such series shall be 16,089.

            Section 2. Dividends and Distributions.

                    (A) Subject to the prior and superior right of the holders
      of any shares of Series C Preferred Stock ranking prior and superior to
      the shares of Series T Preferred Stock with respect to dividends, and pari
      passu with the rights of the holders of shares of Series D Preferred
      Stock, Series E Preferred Stock, Series F Preferred Stock, Series G
      Preferred Stock, Series H Preferred Stock, Series I Preferred Stock,
      Series J Preferred Stock, Series K Preferred Stock, Series L Preferred
      Stock, Series M Preferred Stock, Series N Preferred Stock, Series O
      Preferred Stock, Series P Preferred Stock, Series Q Preferred Stock,
      Series R Preferred Stock and Series S Preferred Stock with respect to
      dividends, subject to the rights of any series of Preferred Stock which
      may hereafter come into existence, the holders of shares of Series T
      Preferred Stock shall be entitled to receive when, as and if declared by
      the Board of Directors out of funds legally available for the purpose,
      dividends in the same amount per share as declared on the Common Stock,
      treating such number of shares of Series T Preferred Stock for this
      purpose as equal to the number of shares of Common Stock into which it is
      then convertible. In the event any dividends are declared or paid on the
      outstanding shares of any series of Preferred Stock with dividend rights
      ranking pari passu with the Series T Preferred Stock, dividends shall
      simultaneously be declared and paid on the outstanding shares of Series T
      Preferred Stock, pari passu with the shares of such other series of
      Preferred Stock with dividend rights ranking pari passu with the Series T
      Preferred Stock, based upon the number of shares of Common Stock into
      which shares of Series T Preferred Stock and such other series of
      Preferred Stock with dividend rights ranking pari passu with the Series T
      Preferred Stock are then convertible. In the event the Corporation shall
      at any time after the date of the filing of this Certificate of
      Determination of Preferences (the "Rights Declaration Date") (i) declare
      any dividend on Common Stock payable in shares of Common Stock, (ii)
      subdivide the outstanding Common Stock, or (iii) combine the outstanding
      Common Stock into a smaller number of shares, then in each such case, the
      amount of Common Stock or other consideration to which holders of shares
      of Series T Preferred Stock were entitled immediately prior to such event
      under the preceding sentences of this Section 2(A) shall be adjusted as
      set forth in Section 4(C) hereof.

                    (B) The Corporation shall declare a dividend or distribution
      on the Series T Preferred Stock as provided in paragraph (A) above prior
      to declaring a dividend payable on shares of Common Stock.

            Section 3. Voting Rights. The holders of shares of Series T
      Preferred Stock shall have the following voting rights:

                    (A) Each holder of Series T Preferred Stock is entitled to a
      number of votes equal to the number of shares of Common Stock into which
      the holder's Series T Preferred Stock is then convertible. In the event
      the Corporation shall at any time after the Rights Declaration Date (i)
      declare any dividend on Common Stock payable in shares of Common Stock,
      (ii) subdivide the outstanding Common Stock, or (iii) combine the
      outstanding Common Stock into a smaller number of shares, then in each
      such case the number of votes per share to which holders of shares of
      Series T Preferred Stock were entitled immediately prior to such event
      shall be adjusted as set forth in Section 4(C) hereof.

                    (B) Except as otherwise provided herein or by law, the
      holders of shares of Series T Preferred Stock and the holders of shares of
      Common Stock (and any authorized series of Preferred Stock convertible
      into shares of Common Stock and with voting rights equal to the number of
      shares of Common Stock into which such series of Preferred Stock is then
      convertible) shall vote together as one class on all matters submitted to
      a vote of shareholders of the Corporation.

                    (C) Except as required by law or under Section 8 hereof,
      holders of Series T Preferred Stock shall have no special voting rights
      and their consent shall not be required (except to the extent they are
      entitled to vote with holders of Common Stock as set forth herein) for
      taking any corporate action.


<PAGE>   3


            Section 4. Conversion Rights.

                    (A) Each holder of Series T Preferred Stock may, at any
      time, in such holder's sole discretion, convert all or any part of such
      holder's shares of Series T Preferred Stock into fully paid and
      nonassessable shares of Common Stock at the rate of ten (10) shares of
      Common Stock for each share of Series T Preferred Stock surrendered for
      conversion.

                    (B) Such conversion may be effected by surrender of such
      holder's certificate or certificates for the shares of Series T Preferred
      Stock to be converted, duly endorsed, at the principal office of the
      Corporation, with a written notice stating (i) that such holder elects to
      convert all or a specified number of shares of Series T Preferred Stock
      into shares of Common Stock, and (ii) the name in which such holder
      desires a certificate for the shares of Common Stock to be issued.
      Promptly thereafter, the Company shall issue and deliver to such holder a
      certificate for the number of shares of Common Stock to which such holder
      shall be entitled. Such conversion shall be deemed to have been made at
      the close of business on the date of such surrender, and such holder shall
      be treated for all purposes as the record holder of such shares of Common
      Stock on that date.

                    (C) In the event the Corporation shall at any time after the
      Rights Declaration Date (i) declare any dividend on Common Stock payable
      in shares of Common Stock, (ii) subdivide the outstanding Common Stock, or
      (iii) combine the outstanding Common Stock into a smaller number of
      shares, then, in each case, the number of shares of Common Stock issuable
      upon the conversion of each share of Series T Preferred Stock shall be
      adjusted by multiplying such amount by a fraction, the numerator of which
      is the number of shares of Common Stock outstanding immediately after such
      event and the denominator of which is the number of shares of Common Stock
      that are outstanding immediately prior to such event.

                    (D) In the event the Corporation shall at any time or from
      time to time after the Rights Declaration Date make or issue, or fix a
      record date for the determination of holders of Common Stock entitled to
      receive, a dividend or other distribution payable in securities of the
      Corporation or any of its subsidiaries, or of any other corporation or
      third party, other than in shares of Common Stock, then, in each such
      event, provisions shall be made so that the holders of Series T Preferred
      Stock shall receive, upon the conversion thereof, securities of the
      Corporation or any of its subsidiaries or of any other corporation or
      third party which they would have received had their stock been converted
      into Common Stock on the date of such event.

              Section 5. Reacquired Shares. Any shares of Series T Preferred
      Stock purchased or otherwise acquired by the Corporation in any manner
      whatsoever shall be retired and canceled promptly after the acquisition
      thereof. All such shares shall upon their cancellation become authorized
      but unissued shares of Preferred Stock and may be reissued as part of a
      new series of Preferred Stock to be created by resolution or resolutions
      of the Board of Directors, subject to the conditions and restrictions on
      issuance set forth herein.

            Section 6. Liquidation, Dissolution or Winding Up.

                    (A) Upon any liquidation (voluntary or otherwise),
      dissolution or winding up of the Corporation, following the first priority
      liquidation preference of the Series C Preferred Stock in the amount of
      $5.00 per share plus any declared but unpaid dividends, and pari passu
      with the liquidation preference of the Series D Preferred Stock in the
      amount of $5.00 per share plus any declared but unpaid dividends ("Series
      D Liquidation Preference"), the liquidation preference of the Series E
      Preferred Stock in the amount of $4.00 per share plus any declared but

      plus any declared but unpaid dividends ("Series T Liquidation

                  (C) Except as required by law or under Section 8 hereof,
      holders of Series U Preferred Stock shall have no special voting rights
      and their consent shall not be required (except to the extent they are
      entitled to vote with holders of Common Stock as set forth herein) for
      taking any corporate action.

            Section 4. Conversion Rights.

                  (A) Each holder of Series U Preferred Stock may, at any time,
      in such holder's sole discretion, convert all or any part of such holder's
      shares of Series U Preferred Stock into fully paid and nonassessable
      shares of Common Stock at the rate of ten (10) shares of Common Stock for
      each share of Series U Preferred Stock surrendered for conversion.

                  (B) Such conversion may be effected by surrender of such
      holder's certificate or certificates for the shares of Series U Preferred
      Stock to be converted, duly endorsed, at the principal office of the
      Corporation, with a written notice stating (i) that such holder elects to
      convert all or a specified number of shares of Series U Preferred Stock
      into shares of Common Stock, and (ii) the name in which such holder
      desires a certificate for the shares of Common Stock to be issued.
      Promptly thereafter, the Company shall issue and deliver to such holder a
      certificate for the number of shares of Common Stock to which such holder
      shall be entitled. Such conversion shall be deemed to

      have been made at the close of business on the date of such surrender, and
      such holder shall be treated for all purposes as the record holder of such
      shares of Common Stock on that date.

                  (C) In the event the Corporation shall at any time after the
      Rights Declaration Date (i) declare any dividend on Common Stock payable
      in shares of Common Stock, (ii) subdivide the outstanding Common Stock, or
      (iii) combine the outstanding Common Stock into a smaller number of
      shares, then, in each case, the number of shares of Common Stock issuable
      upon the conversion of each share of Series U Preferred Stock shall be
      adjusted by multiplying such amount by a fraction, the numerator of which
      is the number of shares of Common Stock outstanding immediately after such
      event and the denominator of which is the number of shares of Common Stock
      that are outstanding immediately prior to such event.

                  (D) In the event the Corporation shall at any time or from
      time to time after the Rights Declaration Date make or issue, or fix a
      record date for the determination of holders of Common Stock entitled to
      receive, a dividend or other distribution payable in securities of the
      Corporation or any of its subsidiaries, or of any other corporation or
      third party, other than in shares of Common Stock, then, in each such
      event, provisions shall be made so that the holders of Series U Preferred
      Stock shall receive, upon the conversion thereof, securities of the
      Corporation or any of its subsidiaries or of any other corporation or
      third party which they would have received had their stock been converted
      into Common Stock on the date of such event.

             Section 5. Any shares of Series U Preferred Stock purchased or
      otherwise acquired by the Corporation in any manner whatsoever shall be
      retired and canceled promptly after the acquisition thereof. All such
      shares shall upon their cancellation become authorized but unissued shares
      of Preferred Stock and may be reissued as part of a new series of
      Preferred Stock to be created by resolution or resolutions of the Board of
      Directors, subject to the conditions and restrictions on issuance set
      forth herein.

                   CERTIFICATE OF DETERMINATION OF PREFERENCES
                                       OF
                            SERIES V PREFERRED STOCK
                                       OF
                                   DISC, INC.

        We, J. Richard Ellis and Henry Madrid, hereby certify that we are the
President and the Chief Financial Officer, respectively, of DISC, INC., a
corporation organized and existing under the General Corporation Law of the
State of California, and further, DO HEREBY CERTIFY:

        That pursuant to the authority conferred upon the Board of Directors by
the Articles of Incorporation of the said Corporation, the said Board of
Directors on September 30, 1999 adopted the following resolution creating a
series of 66,038 shares of Preferred Stock designated as Series V Preferred
Stock, none of which shares have been issued:

               "RESOLVED, that pursuant to the authority vested in the Board of
        Directors of the corporation by the Articles of Incorporation, the Board
        of Directors does hereby provide for the issuance of a series of
        Preferred Stock, no par value, of the Corporation, to be designated
        "Series V Preferred Stock," initially consisting of 66,038 shares and to
        the extent that the designations, powers, preferences and relative and
        other special rights and the qualifications, limitations and
        restrictions of the Series V Preferred Stock are not stated and
        expressed in the Articles of Incorporation, does hereby fix and herein
        state and express such designations, powers, preferences and relative
        and other special rights and the qualifications, limitations and
        restrictions thereof, as follows (all terms used herein which are
        defined in the Articles of Incorporation shall be deemed to have the
        meanings provided therein):

               Section 1. Designation and Amount. The shares of such series
        shall be designated as "Series V Preferred Stock," no par value, and the
        number of shares constituting such series shall be 66,038.

               Section 2. Dividends and Distributions.

                      (A)  Subject to the prior and superior right of the
        holders of any shares of Series C Preferred Stock ranking prior and
        superior to the shares of Series V Preferred Stock with respect to
        dividends, and pari passu with the rights of the holders of shares of
        Series D Preferred Stock, Series E Preferred Stock, Series F Preferred
        Stock, Series G Preferred Stock, Series H Preferred Stock, Series I
        Preferred Stock, Series J Preferred Stock, Series K Preferred Stock,
        Series L Preferred Stock, Series M Preferred Stock, Series N Preferred

<PAGE>   2
        Stock, Series Q Preferred Stock, Series R Preferred Stock, Series S
        Preferred Stock, Series T Preferred Stock and Series U Preferred Stock
        with respect to dividends, subject to the rights of any series of
        Preferred Stock which may hereafter come into existence, the holders of
        shares of Series V Preferred Stock shall be entitled to receive when, as
        and if declared by the Board of Directors out of funds legally available
        for the purpose, dividends in the same amount per share as declared on
        the Common Stock, treating such number of shares of Series V Preferred
        Stock for this purpose as equal to the number of shares of Common Stock
        into which it is then convertible. In the event any dividends are
        declared or paid on the outstanding shares of any series of Preferred
        Stock with dividend rights ranking pari passu with the Series V
        Preferred Stock, dividends shall simultaneously be declared and paid on
        the outstanding shares of Series V Preferred Stock, pari passu with the
        shares of such other series of Preferred Stock with dividend rights
        ranking pari passu with the Series V Preferred Stock, based upon the
        number of shares of Common Stock into which shares of Series V Preferred
        Stock and such other series of Preferred Stock with dividend rights
        ranking pari passu with the Series V Preferred Stock are then
        convertible. In the event the Corporation shall at any time after the
        date of the filing of this Certificate of Determination of Preferences
        (the "Rights Declaration Date") (i) declare any dividend on Common Stock
        payable in shares of Common Stock, (ii) subdivide the outstanding Common
        Stock, or (iii) combine the outstanding Common Stock into a smaller
        number of shares, then in each such case, the amount of Common Stock or
        other consideration to which holders of shares of Series V Preferred
        Stock were entitled immediately prior to such event under the preceding
        sentences of this Section 2(A) shall be adjusted as set forth in Section
        4(C) hereof.

                      (B)  The Corporation shall declare a dividend or
        distribution on the Series V Preferred Stock as provided in paragraph
        (A) above prior to declaring a dividend payable on shares of Common
        Stock.

               Section 3. Voting Rights. The holders of shares of Series V
        Preferred Stock shall have the following voting rights:

                      (A)   Each holder of Series V Preferred Stock is entitled
        to a number of votes equal to the number of shares of Common Stock into
        which the holder's Series V Preferred Stock is then convertible. In the
        event the Corporation shall at any time after the Rights Declaration
        Date (i) declare any dividend on Common Stock payable in shares of
        Common Stock, (ii) subdivide the outstanding Common Stock, or (iii)
        combine the outstanding Common Stock into a smaller number of shares,
        then in each such case the number of votes per share to which holders of
        shares of Series V Preferred Stock were entitled immediately prior to
        such event shall be adjusted as set forth in Section 4(C) hereof.

                      (B)  Except as otherwise provided herein or by law, the
        holders of shares of Series V Preferred Stock and the holders of shares
        of Common Stock (and any authorized series of Preferred Stock
        convertible into shares of Common Stock and with voting rights equal to
        the number of shares of Common Stock into which such series of Preferred
        Stock is then convertible) shall vote together as one class on all
        matters submitted to a vote of shareholders of the Corporation.

                      (C)  Except as required by law or under Section 8 hereof,
        holders of Series V Preferred Stock shall have no special voting rights
        and their consent shall not be required (except to the extent they are
        entitled to vote with holders of Common Stock as set forth herein) for
        taking any corporate action.

               Section 4. Conversion Rights.

                      (A)  Each holder of Series V Preferred Stock may, at any
        time, in such holder's sole discretion, convert all or any part of such
        holder's shares of Series V Preferred Stock into fully paid and
        nonassessable shares of Common Stock at the rate of ten (10) shares of
        Common Stock for each share of Series V Preferred Stock surrendered for
        conversion.

                      (B)  Such conversion may be effected by surrender of such
        holder's certificate or certificates for the shares of Series V
        Preferred Stock to be converted, duly endorsed, at the principal office
        of the Corporation, with a written notice stating (i) that such holder
        elects to convert all or a specified number of shares of Series V
        Preferred Stock into shares of Common Stock, and (ii) the name in which
        such holder desires a certificate for the shares of Common Stock to be
        issued. Promptly thereafter, the Company shall issue and deliver to such
        holder a certificate for the number of shares of Common Stock to which
        such holder shall be entitled. Such conversion shall be deemed to have
        been made at the close of business on the date of such surrender, and
        such holder shall be treated for all purposes as the record holder of
        such shares of Common Stock on that date.

                      (C)  In the event the Corporation shall at any time after
        the Rights Declaration Date (i) declare any dividend on Common Stock
        payable in shares of Common Stock, (ii) subdivide the outstanding Common
        Stock, or (iii) combine the outstanding Common Stock into a smaller
        number of shares, then, in each case, the number of shares of Common
        Stock issuable upon the conversion of each share of Series V Preferred
        Stock shall be adjusted by multiplying such amount by a fraction, the
        numerator of which is the number of shares of Common Stock outstanding
        immediately after such event and the denominator of which is the number
        of shares of Common Stock that are outstanding immediately prior to such
        event.

                      (D)  In the event the Corporation shall at any time or
        from time to time after the Rights Declaration Date make or issue, or
        fix a record date for the determination of holders of Common Stock
        entitled to receive, a dividend or other distribution payable in
        securities of the Corporation or any of its subsidiaries, or of any
        other corporation or third party, other than in shares of Common Stock,
        then, in each such event, provisions shall be made so that the holders
        of Series V Preferred Stock shall receive, upon the conversion thereof,
        securities of the Corporation or any of its

                                       2

        subsidiaries or of any other corporation or third party which they would
        have received had their stock been converted into Common Stock on the
        date of such event.

        Stock purchased or otherwise acquired by the Corporation in any manner
        whatsoever shall be retired and canceled promptly after the acquisition
        thereof. All such shares shall upon their cancellation become authorized
        but unissued shares of Preferred Stock and may be reissued as part of a
        new series of Preferred Stock to be created by resolution or resolutions

        Series U Preferred Stock in the amount of $15.40 per share of series U
        Preferred Stock plus any declared but unpaid dividends (the "Series U

        of shares of stock ranking junior (either as to dividends or upon
        liquidation, dissolution or winding up) to the Series V Preferred Stock
        unless, prior thereto, the holders of shares of Series V Preferred Stock
        shall have received an amount equal to $10.60 per share of Series V

        if any, which rank on a parity with the Series V Preferred Stock, then
        such remaining assets shall be distributed ratably to the holders of
        such parity shares in proportion to their respective liquidation
        preferences.

                   CERTIFICATE OF DETERMINATION OF PREFERENCES
                                       OF
                            SERIES W PREFERRED STOCK
                                       OF
                                   DISC, INC.

     We, J. Richard Ellis and Henry Madrid, hereby certify that we are the
President and the Chief Financial Officer, respectively, of DISC, INC., a
corporation organized and existing under the General Corporation Law of the
State of California, and further, DO HEREBY CERTIFY:

     That pursuant to the authority conferred upon the Board of Directors by the
Articles of Incorporation of the said Corporation, the said Board of Directors
on December 31, 1999 adopted the following resolution creating a series of
30,201 shares of Preferred Stock designated as Series W Preferred Stock, none of
which shares have been issued:

          "RESOLVED, that pursuant to the authority vested in the Board of
     Directors of the corporation by the Articles of Incorporation, the Board of
     Directors does hereby provide for the issuance of a series of Preferred
     Stock, no par value, of the Corporation, to be designated "Series W
     Preferred Stock," initially consisting of 30,201 shares and to the extent
     that the designations, powers, preferences and relative and other special
     rights and the qualifications, limitations and restrictions of the Series W
     Preferred Stock are not stated and expressed in the Articles of
     Incorporation, does hereby fix and herein state and express such
     designations, powers, preferences and relative and other special rights and
     the qualifications, limitations and restrictions thereof, as follows (all
     terms used herein which are defined in the Articles of Incorporation shall
     be deemed to have the meanings provided therein):

          Section 1. Designation and Amount. The shares of such series shall be
     designated as "Series W Preferred Stock," no par value, and the number of
     shares constituting such series shall be 30,201.

          Section 2. Dividends and Distributions.

               Subject to the prior and superior right of the holders of any
     shares of Series C Preferred Stock ranking prior and superior to the shares
     of Series W Preferred Stock with respect to dividends, and pari passu with
     the rights of the holders of shares of Series D Preferred Stock, Series E
     Preferred Stock, Series F Preferred Stock, Series G Preferred Stock, Series
     H Preferred Stock, Series I Preferred Stock, Series J Preferred Stock,
     Series K Preferred Stock, Series L Preferred Stock, Series M Preferred
     Stock, Series N Preferred Stock, Series O Preferred Stock, Series P
     Preferred


<PAGE>   2


     Stock, Series Q Preferred Stock, Series R Preferred Stock, Series S
     Preferred Stock, Series T Preferred Stock, Series U Preferred Stock and
     Series V Preferred Stock with respect to dividends, subject to the rights
     of any series of Preferred Stock which may hereafter come into existence,
     the holders of shares of Series W Preferred Stock shall be entitled to
     receive when, as and if declared by the Board of Directors out of funds
     legally available for the purpose, dividends in the same amount per share
     as declared on the Common Stock, treating such number of shares of Series W
     Preferred Stock for this purpose as equal to the number of shares of Common
     Stock into which it is then convertible. In the event any dividends are
     declared or paid on the outstanding shares of any series of Preferred Stock
     with dividend rights ranking pari passu with the Series W Preferred Stock,
     dividends shall simultaneously be declared and paid on the outstanding
     shares of Series W Preferred Stock, pari passu with the shares of such
     other series of Preferred Stock with dividend rights ranking pari passu
     with the Series W Preferred Stock, based upon the number of shares of
     Common Stock into which shares of Series W Preferred Stock and such other
     series of Preferred Stock with dividend rights ranking pari passu with the
     Series W Preferred Stock are then convertible. In the event the Corporation
     shall at any time after the date of the filing of this Certificate of
     Determination of Preferences (the "Rights Declaration Date") (i) declare
     any dividend on Common Stock payable in shares of Common Stock, (ii)
     subdivide the outstanding Common Stock, or (iii) combine the outstanding
     Common Stock into a smaller number of shares, then in each such case, the
     amount of Common Stock or other consideration to which holders of shares of
     Series W Preferred Stock were entitled immediately prior to such event
     under the preceding sentences of this Section 2(A) shall be adjusted as set
     forth in Section 4(C) hereof.

                  (B)  The Corporation shall declare a dividend or distribution
     on the Series W Preferred Stock as provided in paragraph (A) above prior to
     declaring a dividend payable on shares of Common Stock.

          Section 3. Voting Rights. The holders of shares of Series W Preferred
     Stock shall have the following voting rights:

                  (A)  Each holder of Series W Preferred Stock is entitled to a
     number of votes equal to the number of shares of Common Stock into which
     the holder's Series W Preferred Stock is then convertible. In the event the
     Corporation shall at any time after the Rights Declaration Date (i) declare
     any dividend on Common Stock payable in shares of Common Stock, (ii)
     subdivide the outstanding Common Stock, or (iii) combine the outstanding
     Common Stock into a smaller number of shares, then in each such case the
     number of votes per share to which holders of shares of Series W Preferred
     Stock were entitled immediately prior to such event shall be adjusted as
     set forth in Section 4(C) hereof.

                  (B)  Except as otherwise provided herein or by law, the
     holders of shares of Series W Preferred Stock and the holders of shares of
     Common Stock (and any authorized series of Preferred Stock convertible into
     shares of Common Stock and with voting rights equal to the number of shares
     of Common Stock into which such series of Preferred Stock is then
     convertible) shall vote together as one class on all matters submitted to a
     vote of shareholders of the Corporation.

                  (C)  Except as required by law or under Section 8 hereof,
     holders of Series W Preferred Stock shall have no special voting rights and
     their consent shall not be required (except to the extent they are entitled
     to vote with holders of Common Stock as set forth herein) for taking any
     corporate action.

          Section 4. Conversion Rights.

                  (A)  Each holder of Series W Preferred Stock may, at any time,
     in such holder's sole discretion, convert all or any part of such holder's
     shares of Series W Preferred Stock into fully paid and nonassessable shares
     of Common Stock at the rate of ten (10) shares of Common Stock for each
     share of Series W Preferred Stock surrendered for conversion.

                  (B)  Such conversion may be effected by surrender of such
     holder's certificate or certificates for the shares of Series W Preferred
     Stock to be converted, duly endorsed, at the principal office of the
     Corporation, with a written notice stating (i) that such holder elects to
     convert all or a specified number of shares of Series W Preferred Stock
     into shares of Common Stock, and (ii) the name in which such holder desires
     a certificate for the shares of Common Stock to be issued. Promptly
     thereafter, the Company shall issue and deliver to such holder a
     certificate for the number of shares of Common Stock to which such holder
     shall be entitled. Such conversion shall be deemed to have been made at the
     close of business on the date of such surrender, and such holder shall be
     treated for all purposes as the record holder of such shares of Common
     Stock on that date.

                  (C)  In the event the Corporation shall at any time after the
     Rights Declaration Date (i) declare any dividend on Common Stock payable in
     shares of Common Stock, (ii) subdivide the outstanding Common Stock, or
     (iii) combine the outstanding Common Stock into a smaller number of shares,
     then, in each case, the number of shares of Common Stock issuable upon the
     conversion of each share of Series W Preferred Stock shall be adjusted by
     multiplying such amount by a fraction, the numerator of which is the number
     of shares of Common Stock outstanding immediately after such event and the
     denominator of which is the number of shares of Common Stock that are
     outstanding immediately prior to such event.

                  (D)  In the event the Corporation shall at any time or from
     time to time after the Rights Declaration Date make or issue, or fix a
     record date for the determination of holders of Common Stock entitled to
     receive, a dividend or other distribution payable in securities of the
     Corporation or any of its subsidiaries, or of any other corporation or
     third party, other than in shares of Common Stock, then, in each such
     event, provisions shall be made so that the holders of Series W Preferred
     Stock shall receive, upon the conversion thereof, securities of the
     Corporation or any of its


                                       2
<PAGE>   3
     subsidiaries or of any other corporation or third party which they would
     have received had their stock been converted into Common Stock on the date
     of such event.

          Section 5. Reacquired Shares. Any shares of Series W Preferred Stock
     purchased or otherwise acquired by the Corporation in any manner whatsoever
     shall be retired and canceled promptly after the acquisition thereof. All
     such shares shall upon their cancellation become authorized but unissued
     shares of Preferred Stock and may be reissued as part of a new series of
     Preferred Stock to be created by resolution or resolutions of the Board of
     Directors, subject to the conditions and restrictions on issuance set forth
     herein.

          Section 6. Liquidation, Dissolution or Winding Up.

                  (A)  Upon any liquidation (voluntary or otherwise),
     dissolution or winding up of the Corporation, following the first priority

     $5.00 per share plus any declared but unpaid dividends, and pari passu with

     $5.00 per share plus any declared but unpaid dividends ("Series D

                  (B)  In the event, however, that there are not sufficient
