Business Description

Quantum Corporation ("Quantum" or the "Company"), operating in a single business
segment, designs, develops, and markets information storage products, including
high-performance, high-quality hard disk drives, half-inch cartridge tape
drives, tape drive related products, and solid state disk drives. The half-inch
cartridge tape drives and solid state disk drives are manufactured by the
Company. The Company combines its engineering and design expertise with the
high-volume manufacturing capabilities of its exclusive manufacturing partner,
Matsushita-Kotobuki Electronics Industries, Ltd. ("MKE") of Japan, a subsidiary
of Matsushita Electric Industrial Co., Ltd., to produce high-quality hard disk
drives. Quantum is also involved in the manufacture of magnetoresistive ("MR")
recording heads that are used in hard disk drives produced for the Company.

The Company's strategy is to offer a diversified product portfolio that features
leading-edge technology and high-quality manufacturing for a broad range of
market applications. Inherent in this strategy is a focus on meeting and
anticipating customers' information storage needs and on the research and
development of storage product technology.

The Company markets its products worldwide to major original equipment
manufacturers ("OEMs"), a broad range of distributors, resellers, and systems
integrators.

The Company's information storage business currently includes the following four
components:

Desktop and Portable Storage Products. Quantum designs, develops, and
markets hard disk drives designed to meet the storage needs of desktop
systems. These products are designed for entry-level to high-end
desktop personal computers ("PCs") for use in both home and business
environments.

Workstation and Systems Storage Products. Quantum designs, develops,
and markets technologically advanced hard disk drives for the demanding
storage needs of network servers, work-stations, storage subsystems,
high-end desktop systems, and minicomputers. These products are
designed for storage-intensive applications, such as graphics, disk
arrays, desktop publishing systems, multimedia computing systems, and
networked data bases and file servers.

Specialty Storage Products. Quantum designs, develops, manufactures,
and markets half-inch cartridge tape drives and solid state disk
drives. The tape drives use advanced linear recording technology and a
highly accurate tape guide system to perform data backup for mid-range
and high-end computer systems. The solid state disk drives have the
high execution speeds required for applications such as imaging,
multimedia, video-on-demand, on-line transaction processing, material
requirements planning, and scientific modeling.

Recording Heads. Quantum is involved in the design, development, and
manufacture of MR recording heads used in the Company's products. The
Company believes that MR technology, which provides higher capacity per
disk than conventional thin-film heads, will replace thin-film heads as
the leading recording head technology. The Company does not currently
market thin-film or MR heads to other companies. For

2


most of fiscal 1998, the Company's involvement in the design,
development, and manufacture of recording heads will be through a 49%
ownership interest in a joint venture with MKE as discussed in the
Strategic Developments section.

Quantum operates in an industry characterized by rapid technological change. The
Company is currently concentrating its product development efforts on broadening
its existing disk and tape drive product lines through the introduction of new
products, including new high-capacity hard disk drive products to be
manufactured by MKE, as well as new products targeted specifically for the
increasing storage needs of the desktop market. The Company is also focusing its
efforts on applying its MR technology to new generations of disk drives.

Strategic Developments

Transition in High-Capacity Disk Drive Manufacturing. During fiscal 1997,
Quantum substantially completed the manufacturing transition, committed to in
January 1996, of its high-capacity disk drive products to its strategic partner,
MKE. As part of the transition, the Company discontinued its manufacture of
these products in fiscal 1997 and completed the shut-down of the related
facilities. The related manufacturing work force was terminated in fiscal 1997.
The Company closed, sold, or disposed of certain high-capacity manufacturing
facilities and equipment located in Penang, Malaysia; and Milpitas, California.
Facilities sold included the manufacturing building in Malaysia, which was sold
in the second quarter of fiscal 1997. Expenditures associated with the
transition have substantially been completed. As a result of this transition,
the Company anticipates that it will achieve significant benefits by leveraging
on the high-volume, high-quality manufacturing expertise of MKE.

Purchase of Minority Interest. In February 1997, Quantum acquired the 19%
minority ownership interest in Quantum Peripherals Colorado, Inc. ("QPC"), a
consolidated subsidiary involved in the development and manufacture of recording
heads. The minority ownership interest was acquired in exchange for $3.4 million
and the issuance of 90,000 shares of Redeemable Convertible Participating Series
B Preferred Stock, which were valued at $3.9 million as of the issuance date.

MKE/Quantum Recording Heads Joint Venture. On May 1, 1997, MKE and Quantum
announced the formation of a recording heads joint venture company. Pursuant to
the terms of the transaction, Quantum contributed certain recording heads assets
and operations, will transfer employees of the Company's recording heads
operations and leased certain premises to the joint venture in exchange for a
49% ownership interest in the joint venture; the joint venture assumed $51
million of debt payable to Quantum; and MKE paid Quantum $94 million and
contributed $110 million to the joint venture in exchange for a 51% controlling
ownership interest in the joint venture. The Company anticipates that the joint
venture will leverage Quantum's engineering and design expertise and MKE's
manufacturing expertise in order to fully realize the potential of the MR heads
operations to the benefit of both MKE and Quantum.

Renegotiated MKE Master Agreement. In May 1997, Quantum completed renegotiation
of its master agreement with MKE, which covers the general terms of the business
relationship. The agreement was extended for a period of 10 years. MKE currently
manufactures all of the hard disk drives developed and marketed by Quantum.
Quantum's relationship with MKE, which dates from 1984, is built on Quantum's
engineering and design expertise and MKE's high-volume, high-quality
manufacturing expertise. This agreement with MKE underscores the strong
commitment and working relationship developed with MKE.

speed of applications such as imaging, multimedia, video-on-demand,
on-line transaction processing, material requirements planning and
scientific modeling. In product development environments, the products
can substantially shorten time-to-market. Quantum's SSDs are used like
magnetic disks, however, they achieve near instantaneous access times
by eliminating the latency associated with disk rotation and head seek.
SSD drives include a unique and fully integrated data retention system
with continuous back-up to ensure that data is safely stored in the
event of a power interruption. The Company currently offers the Quantum
ESP5000 Series 5.25-inch form factor SSDs and the Quantum ESP3000
Series 3.5-inch form factor SSDs. Quantum's SSD drives did not
represent a significant amount of the Company's revenues in the fiscal
years ended March 31, 1997 and 1996.

For information regarding the percentage of total revenue contributed by any
class of similar products, refer to Part II, Item 8, Note 15 of the Notes to
Consolidated Financial Statements.

Product Development

For a discussion of product development, refer to Part II, Item 7, Results of
Operations - Research and Development Expenses; and Trends and Uncertainties -
Rapid Technological Change, New Product Development, and Qualification.

Manufacturing

The Company believes that its manufacturing strategies for hard disk drives,
half-inch cartridge disk drives, and solid state disk drives; and its
involvement in the manufacture of MR recording heads are key to its success.

For production of its hard disk drives, the Company depends exclusively on MKE.
MKE produces hard disk drives for Quantum in Japan, Singapore, and Ireland.
MKE's state-of-the-art manufacturing process is highly automated, employing
integrated computer networks and advanced control systems. For additional
discussion of the Company's dependence on MKE, refer to Part II, Item 7, Trends
and Uncertainties - Dependence on MKE Relationship. The Company's relationship
with MKE, which has been continuous since 1984, is currently governed by a
master agreement. The current agreement between the Company and MKE gives MKE
the exclusive worldwide right to manufacture, and the Company the exclusive
worldwide right to design and market, hard disk drives. The Company provides MKE
with forecasts of its requirements and places purchase orders approximately
three months prior to delivery. The Company has only a limited right to modify
these purchase orders. The Company's transactions with MKE are denominated in
U.S. dollars with prices for product purchases negotiated periodically,
generally on a quarterly basis. Thus, fluctuations in the exchange rate have no
material short term impact on Quantum's results of operations. However, such
fluctuations may impact future negotiated prices. For additional discussion of
the MKE master agreement, refer to Part I, Item 1, Strategic Developments -
Renegotiated MKE Master Agreement.

For production of its half-inch cartridge disk drives and solid state disk
drives, the Company operates a manufacturing facility in Colorado Springs,
Colorado; and a related research and development and preproduction facility in
Shrewsbury, Massachusetts.

The Company and its manufacturing partner, MKE, are dependent on suppliers for
components and sub-assemblies, which are essential to the manufacture of the
Company's products. For additional discussion of this dependence, refer to Part
II, Item 7, Trends and Uncertainties - Dependence on Suppliers of Components and
Sub-Assemblies; Component Shortages.

The Company's current hard disk drive product manufacturing relies on MR
recording head technology. The Company is involved in the manufacture of MR
recording heads through a joint venture with MKE. For additional discussion of
the MR recording heads and the joint venture, refer to Part I, Item 1, Strategic
Developments - MKE/Quantum Recording Heads Joint Venture, and Trends and
Uncertainties - MR Recording Heads Development and Manufacturing; and Part II,
Item 8, Note 18 of the Notes to Consolidated Financial Statements.

Sales and Marketing

The Company markets its products directly to desktop personal computer, notebook
and workstation manufacturers and to distributors, resellers and systems
integrators through its worldwide sales force. For additional discussion of
sales and customers, refer to Part II, Item 7, Results of Operations - Sales,
and Trends and Uncertainties - Customer Concentration.

Supporting international sales and operations, Quantum maintains a European
regional headquarters in Neuchatel, Switzerland; an Asia-Pacific regional
headquarters in Singapore; a Japanese headquarters in Tokyo and sales offices
throughout the world. International sales, which include sales to foreign
subsidiaries of United States companies, were 53%, 52% and 53% in fiscal 1997,
1996 and 1995, respectively. For additional information on foreign operations
refer to Part II, Item 8, Note 15 of the Notes to Consolidated Financial
Statements.

Warranty and Service

The Company generally warrants its products against defects for a period of one
to five years from the date of sale. Supporting warranty obligations, the
Company maintains in-house service facilities for refurbishment or repair of its
products in Milpitas, California; Dundalk, Ireland; and Penang, Malaysia. For
additional discussion of warranty, refer to Part II, Item 7, Trends and
Uncertainties - Warranty.

Backlog

The Company's six-month order backlog at May 30, 1997, was approximately $1.350
billion compared to approximately $870 million at June 13, 1996. The backlog
increased approximately 55% year-over-year, reflecting recent introductions of
high-end disk drives in the fourth quarter of fiscal 1997 and the first quarter
of fiscal 1998, stronger demand for half-inch cartridge tape products, and an
overall increase in sales levels.

Backlog includes only firm orders for which the customers have released a
specific purchase order and specified a delivery schedule. Lead time for the
release of purchase orders depends upon the scheduling practices of the
individual customer, and the rate of new order bookings varies from month to
month. For this reason, and the possibility of customer changes in delivery
schedules or cancellations of orders, Quantum's backlog as of any particular
date may not be representative of actual sales for any succeeding period. In
addition, it has been the Company's practice to permit customers to increase or
decrease (including canceling) orders for products with relatively short notice
to the Company. The Company believes that this practice enables customers to
improve the management of their inventory, minimizes the Company's exposure to
disputed accounts receivable and strengthens the Company's relationships with
customers.

Competition

For a discussion of competition, refer to Part II, Item 7, Trends and
Uncertainties - Intensely Competitive Industry.

Patents and Licenses

Quantum has been granted and/or owns by assignment 398 United States patents,
including patents originally issued to its former subsidiary Plus Development
Corporation, and patents originally issued to Digital Equipment Corporation. As
a general rule, these patents have 17-year terms from the date of issuance.
Quantum also has certain foreign patents and applications relative to certain of
the products and technologies. Although Quantum believes that its patents and
applications have significant value, the rapidly changing technology of the
computer industry makes Quantum's future success dependent primarily upon the
technical competence and creative skills of its personnel rather than on patent
protection. See also "Legal Proceedings."

Several companies and individuals have approached Quantum concerning the need
for a license under patented technology that Quantum has assertedly used, or is
assertedly using, in the manufacture and sale of one or more of Quantum's
products. Quantum conducts ongoing investigations into these assertions and
presently believes that any licenses ultimately determined to be required could
be obtained on commercially reasonable terms. However, there is no assurance
that such licenses are presently obtainable, or if later determined to be
required, could be obtained. See also "Legal Proceedings."

Quantum has signed several cross-licensing agreements with Hewlett-Packard, IBM,
Seagate Technology, and Terastor. These agreements enable Quantum to use certain
patents owned by these companies, and certain of these agreements enable these
companies to use certain patents owned by Quantum.

Plant and Equipment

The Company anticipates that it will acquire additional facilities in fiscal
1998 to support expansion of half-inch cartridge tape drive manufacturing,
research and development and other corporate activities.

Employees

At March 31, 1997, the Company had approximately 6,380 regular employees. In
connection with the MKE/Quantum recording heads joint venture, approximately
1,470 Quantum employees will become employees of the joint venture and will
cease to be employees of Quantum (refer to Part I, Item 1, Strategic
Developments -

9


MKE/Quantum Recording Heads Joint Venture; and Part II, Item 7, Trends and
Uncertainties - MR Recording Heads Development and Manufacturing; and Item 8,
Note 18 of the Notes to Consolidated Financial Statements).

In the advanced electronics industry, competition for highly skilled employees
is intense. Quantum believes that a great part of its future success will depend
on its continued ability to attract and retain qualified employees. None of the
Company's employees are represented by a trade union, and the Company has
experienced no work stoppages. Quantum believes that its employee relations are
favorable.


ITEM 2. Properties

The Company has its Corporate headquarters in a leased 37-acre, five-building
campus complex in Milpitas, California. The Company owns a 72-acre, two-building
complex in Shrewsbury, Massachusetts, used for research and development and
production of recording heads; a recording heads research and development
facility in Louisville, Colorado; a repair facility in Penang, Malaysia; and a
distribution and hard disk drive configuration facility in Dundalk, Ireland. The
Company leases a facility in Batam, Indonesia, for manufacturing recording
heads. The Company also leases manufacturing facilities in Colorado Springs,
Colorado. In conjunction with the transition of its high-capacity products
manufacturing to MKE, the Company completed the shut-down of the related
facilities in fiscal 1997. The Company closed the high-capacity manufacturing
operations in Milpitas, California, and in the second quarter of fiscal 1997,
sold the manufacturing plant in Malaysia. Additional warehouse and office space
is leased throughout the world, typically on a short-term basis. The Company
will supplement existing facilities during fiscal 1998 to support customer
requirements. Rent expense was approximately $26 million in fiscal 1997.

Properties associated with recording heads operations were leased to the
MKE/Quantum recording heads joint venture in May 1997. For additional

ITEM 7. Management's Discussion and Analysis of Financial Condition and Results
of Operations

Results of Operations

Fiscal 1997 Compared with Fiscal 1996

Sales. Sales in fiscal 1997 increased 20%, to $5.3 billion, compared with sales
of $4.4 billion in fiscal 1996. The increase reflected an increase in shipments
of disk drives, tape drives, and tape drive-related products, as well as an
increase in the average drive price. The increase in the average drive price
reflected a change in sales mix to more advanced, larger-capacity drives; market
demand; and the limited market availability of higher-capacity drives. Partially
offsetting the increase in sales was a decline (particularly in the first
through third quarters of fiscal 1997) in high-end disk drive sales. This
decline resulted from the transition of the manufacture of high-end disk drives
to MKE during fiscal 1997, with older products ceasing production in July 1996,
and new high-end drives not ramping until the third and fourth quarters of
fiscal 1997.

Sales to the Company's top five customers were 38% of sales in fiscal 1997,
compared with 44% in fiscal 1996. Sales to Compaq Computer, Inc. were $562
million, or 11% of sales, in fiscal 1997, compared with $522 million, or 12% of
sales, in fiscal 1996. Sales to Hewlett Packard were $562 million, or 11% of
sales, in fiscal 1997, and were less than 10% of sales in fiscal 1996. Sales to
Apple Computer, Inc. were less than 10% of sales in fiscal 1997, compared with
$473 million, or 11% of sales, in fiscal 1996.

The split of fiscal 1997 sales between OEMs and distribution channels was $3.3
billion and $2.0 billion, or 63% and 37% of sales, respectively, compared with
$3.1 billion and $1.3 billion, or 71% and 29% of sales, respectively, in fiscal
1996. Sales to the OEMs and the distribution channels were based on product
availability and demand.

Gross Margin Rate. The gross margin rate increased 2.2 percentage points to
14.5% in fiscal 1997, from 12.3% in fiscal 1996. The increase reflected a higher
proportion of tape drive and tape drive related product sales in fiscal 1997,
compared to fiscal 1996, as these products achieved a higher gross margin rate
than sales of other products of the Company. The 2.2 percentage point gross
margin rate increase in fiscal 1997 also reflected the impact of a resizing
charge in fiscal 1996 of $38 million, of which $36 million impacted the gross
margin. The fiscal 1996 gross margin rate would have been 13.1% without the
resizing charge.

Research and Development Expenses. In fiscal 1997, the Company's investment in
research and development was $291 million, or 5.5% of sales, compared with $239
million, or 5.4% of sales, in fiscal 1996. The $52 million increase in research
and development spending reflected higher expenses related to preproduction
activity for a number of new products for both the desktop and high-capacity
drive markets. Research and development spending also reflected management's
continuing focus on the development and timely introduction of new information
storage products and technologies. As a percentage of sales, research and
development expenses in fiscal 1998 are expected to be consistent with those of
fiscal 1997.

Sales and Marketing Expenses. Sales and marketing expenses in fiscal 1997 were
$149 million, or 2.8% of sales, compared with $142 million, or 3.2% of sales in
fiscal 1996. The fiscal 1997 decline in sales and marketing expenses as a
percentage of sales reflected the increase in sales and management imposed
spending constraints early in the year. As a percentage of sales, sales and
marketing expenses in fiscal 1998 are expected to be consistent with those of
fiscal 1997.

General and Administrative Expenses. General and administrative expenses in
fiscal 1997 were $87 million, or 1.6% of sales, compared with $65 million, or
1.5% of sales, in fiscal 1996. The increase in expenses in fiscal 1997 reflected
expansion of the Company's infrastructure. As a percentage of sales, general and
administrative expenses in fiscal 1998 are expected to be slightly above those
of fiscal 1997 to support business activities.

Interest and Other Income/Expense. Net interest and other income and expense in
fiscal 1997 was $41 million net expense, compared with $28 million net expense
in fiscal 1996, reflecting an increase in interest expense as a result

13


of an approximately $153 million increase in the average amount of debt
outstanding in fiscal 1997, compared with fiscal 1996. The debt was utilized to
finance operations.

Income Taxes. The effective tax rate in fiscal 1997 was 26%, compared with 36%
in fiscal 1996. The decrease in the effective tax rate was attributable
primarily to the benefit of foreign earnings taxed at less than the U.S. rate
and a reversal of the federal valuation allowance previously provided for
certain state-deferred tax assets. The federal valuation allowance was reversed
in fiscal 1997 as a result of the realization of the federal deferred tax assets
through tax planning. For financial reporting purposes, the Company has provided
a valuation allowance for certain deferred tax assets that are expected to
reverse over a 15 year period. The Company believes that the valuation allowance
is needed to reduce the deferred tax asset to an amount that is more likely than
not to be realized. The Company has concluded that taxable income expected to be
generated over future years, combined with the reversal of existing taxable
temporary differences, will be sufficient to realize the benefits of the
remaining deferred tax assets.

Net Income. After tax earnings increased to a net income of $148.5 million in
fiscal 1997, from a net loss of $90.5 million in fiscal 1996. The change to a
net income in fiscal 1997 from a net loss in fiscal 1996 reflects the impact of
the $209 million fiscal 1996 charge related to the transition of high-capacity
product manufacturing to MKE.


Fiscal 1996 Compared with Fiscal 1995

Sales. Sales in fiscal 1996 increased 31%, to $4.4 billion, compared with sales
of $3.4 billion in fiscal 1995. The increase reflected an increase in drive
shipments and a change in sales mix to more advanced, larger-capacity products.
The increase was partially offset by a decline in average drive prices for older
products. The increase in sales also reflected a full year's sale of products
acquired in the October 3, 1994, purchase of the Disks, Heads and Tapes
Businesses of the Storage Business Unit of Digital Equipment Corporation (the
"Acquired Businesses"). On a pro forma basis, the Company's sales in fiscal 1995
would have been $3.8 billion had the acquisition of the Acquired Businesses
occurred at the beginning of fiscal 1995.

Sales to the Company's top five customers were 44% of sales in fiscal 1996,
compared to 46% in fiscal 1995. Sales to Compaq Computer, Inc. were $522
million, or 12% of sales, in fiscal 1996, compared to $536 million, or 16% of
sales, in fiscal 1995. Sales to Apple Computer, Inc. were $473 million, or 11%
of sales, in fiscal 1996, compared with $404 million, or 12% of sales, in fiscal
1995.

The split of fiscal 1996 sales between OEMs and distribution channels was $3.1
billion and $1.3 billion, or 71% and 29% of sales, respectively, compared with
$2.5 billion and $0.9 billion, or 75% and 25% of sales, respectively, in fiscal
1995. Sales to distribution channels increased during fiscal 1996 as the Company
widened its customer base.

Gross Margin Rate. The gross margin rate decreased to 12.3% in fiscal 1996,
compared with 16.7% in fiscal 1995. The decrease in gross margin rate was
attributable to product qualification issues that contributed to higher costs
and lower-than-expected unit volumes in the high-capacity product line. In
addition, a $38 million resizing charge recorded in fiscal 1996 impacted the
gross margin by $36 million. Without this resizing charge, the gross margin rate
for fiscal 1996 would have been 13.1%.

Research and Development Expenses. In fiscal 1996, the Company invested $239
million, or 5.4% of sales, in research and development, compared with $169
million, or 5.0% of sales, in fiscal 1995. The increase in fiscal 1996 reflected
the impact of a full year of expenses for the Acquired Businesses, along with
higher expenses related to preproduction activity for a larger number of new
products.

Sales and Marketing Expenses. Sales and marketing expenses in fiscal 1996 were
$142 million, or 3.2% of sales, compared with $108 million, or 3.2% of sales, in
fiscal 1995. The increase in expenses in fiscal 1996 was due primarily to the
costs associated with supporting the Company's higher sales volume.

14


General and Administrative Expenses. General and administrative expenses in
fiscal 1996 were $65 million, or 1.5% of sales, compared with $52 million, or
1.5% of sales, in fiscal 1995. The increase in expenses in fiscal 1996 reflected
expansion of the Company's infrastructure.

Other Operating Charges. In fiscal 1996, the Company included in results of
operations a charge of $209 million related to the transition of manufacturing
for the high-capacity products to MKE. The charge was comprised of reduction in
work force of approximately $10 million; write-down of capital assets of
approximately $45 million; incremental inventory write-downs and excess purchase
commitment accruals of approximately $144 million; and other charges of
approximately $10 million. These amounts reflect the provision for closing the
manufacturing facilities in Penang, Malaysia, and Milpitas, California.

As a result of the acquisition of the Acquired Businesses in fiscal 1995, the
Company incurred a charge of $73 million, which included $68 million of
purchased in-process research and development and $5 million in related merger
costs. Merger costs comprised of incremental integration costs incurred through
the end of the quarter in which the acquisition was consummated.

Interest and Other Income/Expense. Net interest and other income and expense in
fiscal 1996 was $28 million net expense, compared with $16 million net expense
in fiscal 1995. The increase in net expense in fiscal 1996 resulted from
interest expense on higher levels of debt used to finance operations.

Income Taxes. The effective tax rate in fiscal 1996 was 36%, compared with 44%
in fiscal 1995. The decrease in the effective tax rate was attributable
primarily to the realization of deferred tax assets previously reserved and
lower overall state taxes, offset by a reduction in the benefit of foreign
earnings taxed at less than the U.S. rate.

Net Income/Loss. After tax earnings decreased to a net loss of $90.5 million in
fiscal 1996 from a net income of $81.6 million in fiscal 1995. The change to a
net loss in fiscal 1996 from a net income in fiscal 1995 reflected the impact of
the $209 million fiscal 1996 charge related to the transition of high-capacity
product manufacturing to MKE.

Liquidity and Capital Resources

The Company generated improved cash flow from operations, aggregating $313
million in fiscal 1997. At March 31, 1997, the Company had $345 million in cash
and cash equivalents, compared to $165 million at March 31, 1996. Cash was
provided by operating activities, primarily from net income and a decrease in
inventory, and was partially offset by an increase in accounts receivable. Cash
used in investing activities reflected investment in property and equipment.
Cash was also provided by financing activities as a result of proceeds from the
issuance of common stock (primarily from the Employee Stock Purchase Plan) and
from the mortgage arrangement, described below, partially offset by net pay-down
on the senior credit facility.

The Company has a senior credit facility that includes a $56.3 million term loan
and a $325 million revolving credit line with a $110 million outstanding balance
at March 31, 1997. The term loan, which began to amortize on December 31, 1996,
will amortize over six remaining quarterly payments.

The Company expects to spend approximately $200 million for capital equipment,
expansion of the Company's facilities, and leasehold improvements in fiscal
1998. These capital expenditures will support the tapes business, research and
development, general corporate operations, and the Company's involvement in the
recording heads operations. The Company believes that it will be able to fund
these capital requirements at least through fiscal 1998. Refer to the Future
Capital Needs section of the Trends and Uncertainties section for additional
discussion of capital.

The Company extended until September 1997 an $85 million unsecured Letter of
Credit facility with certain banks to issue standby letters of credit to MKE and
its affiliates.

15


In September 1996, the Company entered into a $42 million mortgage financing
related to certain domestic facilities at an effective interest rate of
approximately 10.1%. The term of the mortgage is 10 years, with monthly payments
based on a 20-year amortization period, and a balloon payment at the end of the
10-year term.

The Company believes that its existing capital resources, including credit
facilities and any cash generated from operations, will be sufficient to meet
all currently planned expenditures and sustain operations for the next fiscal
year. However, this belief assumes that operating results and cash flow from
operations will meet the Company's expectations, and actual results could vary
due to the factors described in the Trends and Uncertainties section which
follows.

Refer to Note 6 of the Notes to Consolidated Financial Statements for additional
information regarding debt.

Trends and Uncertainties

Operating in the information storage industry, Quantum is affected by numerous
trends and uncertainties, some of which are specific to the industry while
others relate more specifically to Quantum. These are discussed below.

Trends and Uncertainties - Information Storage Industry

The numerous trends and uncertainties inherent in the information storage
industry are summarized below. Following the summary is a discussion of how
these trends and uncertainties specifically impact the Company.

o Intense competition - The information storage products industry in
general, and the disk drive industry in particular, is characterized by
intense competition that results in rapid price erosion; short product
life cycles; and continuous introduction of new, more cost-effective
products offering increased levels of capacity and performance.

o Rapid technological change - Technology advancement in the information
storage industry is increasingly rapid.

o Customer concentration - High-purchase-volume customers for information
storage products are concentrated within a small number of computer
system manufacturers, distribution channels, and system integrators.

o Fluctuating product demand - The demand for hard disk drive products
depends on the demand for the computer systems in which hard disk
drives are used, which in turn is affected by computer system product
cycles and by prevailing economic conditions.

o Intellectual property conflicts - The hard disk drive industry has been
characterized by significant litigation relating to patent and other
intellectual property rights.

Intensely Competitive Industry. To compete within the information storage
industry, Quantum frequently introduces new products and transitions to newer
versions of existing products. Product introductions and transitions are
significant to the operating results of Quantum, and if they are not successful,
the Company would be materially and adversely affected. The hard disk drive
industry also tends to experience periods of excess product inventory and
intense price competition. If price competition intensifies, the Company may be
forced to lower prices more than expected, which could materially adversely
affect the Company. In addition, the Company's customers could commence the
manufacture of disk and tape drives for their own use or for sale to others. Any
such loss of customers could have a material adverse effect on the Company.

Quantum faces direct competition from a number of companies, including Seagate,
Western Digital, IBM (which recently increased its investment in its storage
business), Maxtor and Exabyte. In the event that the Company is unable to
compete effectively with these or any other company, the Company would be
materially adversely affected. The Company's information storage product
competition can be further broken down as follows:

16


Desktop Storage Products. In the market for desktop products, Quantum
competes primarily with Seagate, Western Digital, and Maxtor. Quantum and
its competitors have developed and are developing a number of products
targeted at particular segments of this market, such as business users and
home PC buyers, and factors such as time to market can have a significant
effect on the success of any particular product. The desktop market is
characterized by more competitors and shorter product life cycles than the
hard disk drive market in general.

Workstation and System Storage Products. The Company faces competition in
the high-capacity disk drive market primarily from Seagate and IBM.
Seagate has the largest share of the market for high-capacity disk drives.
Although the same competitive factors identified above as being generally
applicable to the overall disk drive industry apply to high-capacity disk
drives, the Company believes that the performance and quality of its
products are more important to the users in this market than to users in
the desktop market. The Company's success in the high-capacity market
during the foreseeable future is dependent on the successful development,
timely introduction, and market acceptance of key new products, as to
which there can be no assurance.

Specialty Storage Products. In the market for tape drives, the Company
competes with other companies that have tape drive product offerings. The
Company targets a market segment that requires a mission critical backup
system and competes in this segment based on the reliability and
durability of its tape drives. Although the Company has experienced
excellent market acceptance of its tape drive products, the market could
become significantly more competitive at any time during fiscal 1998 or
beyond. As a result, the Company could experience increased price
competition. If price competition occurs, the Company may be forced to
lower prices, in which case the Company could be materially adversely
affected.

Rapid Technological Change, New Product Development, and Qualification. The
combination of an environment of rapid technological changes, short product life
cycles and competitive pressures results in gross margins on specific products
decreasing rapidly. Accordingly, any delay in introduction of more advanced and
more cost-effective products can result in significantly lower sales and gross
margins. The Company's future is therefore dependent on its ability to
anticipate what customers will demand and to develop the new products to meet
this demand. The Company must also qualify new products with its customers,
successfully introduce these products to the market on a timely basis, and
commence volume production to meet customer demands. For example, during the
first quarter of fiscal 1998 the Company expects to introduce a new desktop
product that will account for a significant portion of the Company's sales.
There can be no assurance that the Company will successfully qualify this new
desktop product with its customers on a timely basis or that such product will
be produced in sufficient quantities to meet customer demand. Due to these
factors, the Company expects that sales of new products will continue to account
for a significant portion of its future sales and that sales of older products
will decline accordingly.

The Company is frequently in the process of qualifying new products with its
customers. The customer qualification process for disk drive products,
particularly high-capacity products, can be lengthy, complex, and difficult. In
addition, the Company transitioned the manufacturing of its high capacity
products to MKE during the first half of fiscal 1997, and MKE has only recently
begun volume production of such high-capacity products. In the event that the
Company is unable to obtain additional customer qualifications for new products
in a timely manner, or at all, or in the event that MKE is unable to continue to
manufacture such products in volume and with consistent high quality, the
Company would be materially adversely affected.

There can be no assurance that the Company will be successful in the development
and marketing of any new products and components in response to technological
change or evolving industry standards, that the Company will not experience
difficulties that could delay or prevent the successful development,
introduction and marketing of these products and components; or that the
Company's new products and components will adequately meet the requirements of
the marketplace and achieve market acceptance. In addition, technological
advances in magnetic, optical or other technologies, or the development of new
technologies, could result in the introduction of competitive products with
superior performance to and substantially lower prices than the Company's
products.

17


Further, the Company's new products and components are subject to significant
technological risks. If the Company experiences delays in the commencement of
commercial shipments of new products or components, the Company could experience
delays or loss of product sales. If the Company is unable, for technological or
other reasons, to develop and introduce new products in a timely manner in
response to changing market conditions or customer requirements, the Company
would be materially adversely affected.

Customer Concentration. In addition to the information storage industry and the
Company's customer base being concentrated, the customers generally are not
obligated to purchase any minimum volume of the Company's products, and the
Company's relationships with its customers are generally terminable at will by
its customers.

Sales of the Company's desktop products, which comprise a majority of its
overall sales, were concentrated with several key customers in fiscal 1997 and
1996. Sales to the top five customers of the Company represented 38% and 44% of
total sales in fiscal 1997 and 1996, respectively. In addition, the Company is
unable to predict whether or not there will be any significant change in demand
for any of its customers' products in the future. In the event that any such
changes result in decreased demand for the Company's products, whether by loss
of or delays in orders, the Company could be materially adversely affected.

Fluctuation in Product Demand. Fluctuation in demand for the Company's products
generally results in fluctuations in the Company's operating results. Demand for
computer systems-especially in the PC market segment, where the Company derives
a significant amount of its disk drive sales-has historically been subject to
significant fluctuations. Such fluctuations in end-user demand have in the past,
and may in the future, result in the deferral or cancellation of orders for the
Company's products, each of which could have a material adverse effect on the
Company. During the past several years, there has been significant growth in the
demand for PCs, a portion of which represented sales of PCs for use in the home.
However, many analysts predict that future growth may be at a moderately slower
rate than the rate experienced in recent years.

Sales of tape drives and tape drive-related products, although a less
significant component of sales for the Company than sales of disk drive
products, have tended to be more stable. The Company has experienced longer
product cycles for its tape drives and tape drive-related products, compared
with the short product cycles of disk drive products. However, there is no
assurance that this trend will continue.

The Company could experience decreases in demand for its products in the future,
which could have a material adverse effect on the Company.

The hard disk drive industry has also been subject, from time to time, to
seasonal fluctuations in demand. The Company has typically experienced
relatively flat demand in the quarter ending September 30 compared with the
quarter ending June 30, and increasing demand throughout the quarters ending
December 31 and March 31. The Company's shipments tend to be highest in the
third month of each quarter, and failure by the Company to complete shipments in
the final month could adversely affect the Company's operating results for that
quarter.

Intellectual Property Matters. From time to time, the Company is approached by
companies and individuals alleging Quantum's need for a license under patented
technology that Quantum assertedly uses. If required, there can be no assurance
that licenses to any such technology could be obtained or obtained on
commercially reasonable terms. Adverse resolution of any intellectual property
litigation could subject the Company to substantial liabilities and require it
to refrain from manufacturing certain products. In addition, the costs of
engaging in such litigation may be substantial, regardless of the outcome.

Trends and Uncertainties More Specific to Quantum

There are certain trends and uncertainties that relate more specifically to
Quantum and are not necessarily indicative of the information storage industry
as a whole. These trends and uncertainties include dependence on MKE for the
manufacture of the disk drives that Quantum develops and markets, costs
associated with the MR recording head development and manufacture, the recently
announced recording heads joint venture with MKE, dependence on suppliers,
component shortages, future capital needs, warranty costs, foreign
manufacturing, and price volatility of

18


Quantum common stock. For information regarding litigation refer to Note 13 of
the Notes to Consolidated Financial Statements.

Dependence on MKE Relationship. Quantum is dependent on MKE for the manufacture
of its disk drive products. Approximately 81% of the Company's fiscal 1997 sales
were derived from products manufactured by MKE. The transition of the
manufacturing of the Company's high-capacity products to MKE in fiscal 1997 has
resulted in an increased dependence on MKE. The Company's relationship with MKE
is therefore critical to the Company's business and financial performance.

The Company's dependence on MKE entails, among others, the following principal
risks:

Quality and Delivery. The Company relies on MKE's ability to bring new
products rapidly to volume production at low cost, to meet the Company's
stringent quality requirements, and to respond quickly to changing product
delivery schedules from the Company. This requires, among other things,
close and continuous collaboration between the Company and MKE in all
phases of design, engineering, and production. The Company's business and
financial results would be adversely affected if products manufactured by
MKE fail to satisfy the Company's quality requirements or if MKE is unable
to meet the Company's delivery commitments. In the event MKE is unable to
satisfy Quantum's production requirements, the Company would not have an
alternative manufacturing source to meet the demand without substantial
delay and disruption of the Company's operations. As a result, the Company
would be materially adversely affected.

Volume and Pricing. MKE's production schedule is based on the Company's
forecasts of its product purchase requirements, and the Company has only
limited rights to modify short-term purchase orders issued to MKE.
Further, the demand in the desktop business is inherently volatile, and
there is no assurance that the Company's forecasts are accurate. In
addition, the Company periodically negotiates pricing arrangements with
MKE. The failure of the Company to accurately forecast its requirements,
which could lead to inventory shortages or surpluses, or the failure to
reach pricing agreements reasonable to the Company would have a material
adverse effect on the Company.

Manufacturing Capacity and Capital Commitment. The Company believes that
MKE's current and committed manufacturing capacity should be adequate to
meet the Company's requirements at least through the end of fiscal 1998.
The Company's future growth will require, however, that MKE continue to
devote substantial financial resources to property, plant and equipment
and working capital to support manufacture of the Company's products, as
to which there can be no assurance. In the event that MKE is unable or
unwilling to meet the Company's manufacturing requirements, there can be
no assurance that the Company would be able to obtain an alternate source
of supply. Any such failure to obtain an alternative source would have a
material adverse effect on the Company.

MR Recording Heads Development and Manufacturing. Since the fiscal 1995
acquisition of MR recording heads technology as part of the acquisition of
certain businesses of the Storage Business Unit of Digital Equipment
Corporation, Quantum has made significant efforts to advance the development of
its MR recording heads capability. The Company believes that MR head technology,
which enables higher capacity per disk than conventional thin-film inductive
heads, will replace inductive heads as the leading recording head technology.
Although the Company currently obtains the majority of its MR heads from outside
sources, the Company believes that by manufacturing MR heads it has developed
in-depth knowledge of MR head technology. This knowledge is leveraged in the
research, development, and production of disk drive products that utilize MR
head technology. In addition, the Company believes that having a captive supply
of MR heads lowers the risk of MR head supply shortages that may occur in the
future as a result of increased requirements for disk drive products that
utilize MR recording heads. However, MR technology is relatively complex and, to
date, the Company's manufacturing yields for its MR heads have been lower than
would be necessary for cost effective production of MR recording heads.

As discussed in the Strategic Development section, MKE and Quantum agreed to
form a joint venture to partner in the research, development, and production of
MR heads and technology. Quantum believes that through MKE's manufacturing
expertise, the potential of the MR heads operations will be realized to the
benefit of both MKE and

19


Quantum. However, cost-effective production of MR recording heads is not
expected to be realized until late fiscal 1998 at the earliest. Until that time,
the Company will incur losses based on its pro rata ownership interest in the
new joint venture. However, there can be no assurance that the benefits of the
joint venture will be realized on a timely basis or at all. There is an
additional uncertainty associated with maintaining or increasing the supply of
MR recording heads used in the manufacture of disk drives. There are limited
alternative sources of supply for MR recording heads. In the event that current
sources of MR recording heads, which include Quantum's MR heads operations that
will become part of the joint venture, do not meet disk drive production
requirements, there can be no assurance that the Company will be able to locate
and obtain adequate supplies from alternative sources. A shortage of MR
recording heads would materially adversely affect the Company.

Dependence on Suppliers of Components and Sub-Assemblies; Component Shortages.
The Company and its manufacturing partner, MKE, are dependent on qualified
suppliers for components and sub-assemblies, including recording heads, media,
and integrated circuits, which are essential to the manufacture of the Company's
products. In connection with certain products, the Company and MKE qualify only
a single source for certain components and sub-assemblies, which can magnify the
risk of shortages. Component shortages have constrained the Company's sales
growth in the past, and the Company believes that the industry will periodically
experience component shortages. If such shortages occur, or if the Company
experiences quality problems with component suppliers, shipments of products
could be significantly delayed or costs significantly increased, which would
have a material adverse effect on the Company.

Future Capital Needs. The information storage business is capital-intensive.
Although the Company expects long-term capital requirements related to its
involvement in the development and manufacture of MR recording heads to decline
as a result of the announced joint venture with MKE, the Company believes that
it will need significant additional financial resources over the next several
years for capital expenditures, working capital, and research and development,
in order to remain competitive in the information storage business. The Company
believes that it will be able to fund these capital requirements at least
through fiscal 1998. However, if the Company decides to increase its capital
expenditures further or sooner than presently contemplated, or if results of
operations do not meet the Company's expectations, the Company will require
additional debt or equity financing. There can be no assurance that such
additional funds will be available to the Company or will be available on
favorable terms. The Company may also require additional capital for other
purposes not presently contemplated. If the Company is unable to obtain
sufficient capital, it could be required to curtail its capital equipment and
research and development expenditures, which could adversely affect the Company.

Warranty. Quantum generally warrants its products against defects for a period
of one to five years. A provision for estimated future costs relating to
warranty expense is recorded when products are shipped. The actual warranty
expenditures could have a material unfavorable impact on the Company if the
actual rate of unit failure or the cost to repair a unit is greater than what
the Company has used in estimating the warranty expense accrual.

Risks Associated with Foreign Manufacturing. Many of the Company's products are
currently manufactured outside the United States. As a result, the Company is
subject to certain risks associated with contracting with foreign manufacturers,
including obtaining requisite United States and foreign governmental permits and
approvals, currency exchange fluctuations, currency restrictions, political
instability, labor problems, trade restrictions, and changes in tariff and
freight rates.

Foreign Exchange Contracts. The Company manages the impact of foreign currency
exchange rate changes on certain foreign currency receivables and payables using
foreign currency forward exchange contracts. With this approach the Company
expects to minimize the impact of changing foreign exchange rates on the
Company's net income. However, there can be no assurance that all foreign
currency exposures will be adequately managed, and the Company could incur
material charges as a result of changing foreign exchange rates. Refer to Note 2
of the Notes to Consolidated Financial Statements for additional information
regarding foreign currency forward exchange contracts.

Volatility of Stock Price. The market price of the Company's common stock has
been, and may continue to be, extremely volatile. Factors such as new product
announcements by the Company or its competitors; quarterly

20


fluctuations in the operating results of the Company, its competitors, and other
technology companies; and general conditions in the computer market may have a
significant impact on the market price of the common stock. In particular, if
the Company were to report operating results that did not meet the expectations
of the analysts, the market price of the common stock could be materially
adversely affected.

QUANTUM CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS


Note 1: Summary of Significant Accounting Policies

Nature of Business: Quantum Corporation ("Quantum" or the "Company"), operating
in a single business segment, designs, develops, and markets information storage
products, including high-performance, high-quality hard disk drives, half-inch
cartridge tape drives, tape drive-related products, and solid state disk drives.
The half-inch cartridge tape drives and solid state disk drives are manufactured
by the Company. Quantum is also involved in the design, development, and
manufacture of magnetoresistive ("MR") recording heads that are used in the
Company's hard disk drives, which are manufactured by the Company's exclusive
manufacturing partner, Matsushita-Kotobuki Electronics Industries, Ltd. ("MKE")
of Japan (refer to Note 18 of the Notes to Consolidated Financial Statements).

Quantum's products meet the storage requirements of workstations, network
servers, disk arrays, high-end to entry-level desktop personal computers, and
minicomputers. The Company markets its products directly to major original
equipment manufactures (OEMs) and through a broad range of distributors,
resellers, and systems integrators worldwide.

Accounting Policies: The summary of significant accounting policies is presented
to assist the reader in understanding and evaluating the consolidated financial
statements. These policies are in conformity with generally accepted accounting
principles.

Financial Statement Presentation: The accompanying consolidated financial
statements include the accounts of the Company and its majority-owned
subsidiaries. All material intercompany accounts and transactions have been
eliminated. Certain amounts in prior periods have been reclassified to conform
to current presentation.

The preparation of the consolidated financial statements of the Company in
conformity with generally accepted accounting principles requires management to
make estimates and assumptions that affect the reported amount of assets and
liabilities at the date of the financial statements and the reported amount of
revenues and expenses during the period. These estimates are based on
information available as of the date of the financial statements. Actual results
may differ from the estimates and assumptions used in preparing the consolidated
financial statements.

Revenue Recognition: Revenue from sales of products is recognized on shipment to
customers, with provision made for estimated returns.

Foreign Currency Translation and Transactions: Assets, liabilities, and
operations of foreign offices and subsidiaries are recorded based on the
functional currency of the entity. For a majority of the Company's material
foreign operations, the functional currency is the U.S. Dollar. Although over
half of the Company's sales are made to customers in non-U.S. locations and all
of the Company's hard disk drive products are manufactured in Japan, Singapore
and Ireland by MKE, a majority of the Company's material transactions are
denominated in U.S. dollars. Accordingly, the application of Statement of
Financial Accounting Standards ("SFAS") No. 52, "Foreign Currency Translation,"
to the Company's historical financial statements has resulted in transaction or
translation gains or losses that are immaterial to the Company's consolidated
financial statements for any year presented. The effect of foreign currency
exchange rate fluctuations on cash flows was also immaterial for the years
presented. Assets and liabilities denominated in other than the functional
currency are remeasured each month with the remeasurement gain or loss recorded
in other income.

Foreign Exchange Contracts: The effect of foreign currency rate changes on the
remeasurement of certain assets and liabilities denominated in a foreign
currency are managed using foreign currency forward exchange contracts. Foreign
currency forward exchange contracts represent agreements to exchange the
currency of one country for the currency of another country at an agreed-upon
price, on an agreed-upon settlement date. Foreign currency forward exchange
contracts are accounted for by the fair value method. Foreign currency forward
exchange contracts are carried on the balance sheet at fair value, with changes
in that value recognized in other income.

27


Net Income (Loss) Per Share: Net income (loss) per share amounts are computed by
dividing income or loss amounts by the weighted average of common and common
equivalent shares (when dilutive) outstanding during the period. Primary net
income per share computations for fiscal 1997 and 1995 were computed based on
weighted average shares outstanding, including the dilutive impact of common
stock equivalents, which consist of outstanding stock options. Net income per
share computed on a fully diluted basis for fiscal 1997 and 1995 assumes
conversion of the Company's outstanding convertible subordinated debentures. The
primary and fully diluted net loss per share in fiscal 1996 was computed based
on the Company's simple weighted average shares outstanding for the fiscal year,
as the impact of stock options and convertible subordinated debt was
anti-dilutive.

During fiscal 1997, convertible subordinated debentures were converted into
14,644,000 shares of Common Stock. Had the debentures converted as of April 1,
1996, primary earnings per share for fiscal 1997 would have been $1.12.

In February 1997, the Financial Accounting Standards Board issued Statement No.
128, "Earnings per Share," which is required to be adopted in the Company's
fiscal quarter ending December 31, 1997. At that time, the Company will be
required to change the method currently used to compute earnings per share and
to restate all prior periods. Under the new requirements, primary earnings per
share is replaced by basic earnings per share, for which the dilutive effect of
stock options will be excluded. Under Statement 128, basic earnings per share
will exceed previously computed primary earnings per share in periods with net
income. The impact of Statement 128 on the calculation of fully diluted earnings
per share is not expected to be material.

Cash Equivalents and Marketable Securities: The Company considers all highly
liquid debt instruments with a maturity of three months or less from the date of
purchase to be cash equivalents.

The Company has classified its entire investment portfolio as
available-for-sale. Available-for-sale securities are carried at fair value,
with material unrealized gains and losses reported in shareholders' equity. The
amortized cost of debt securities is adjusted for amortization of premiums and
accretion of discounts to maturity. Such amortization is included in interest
income along with interest earned. Realized gains or losses and declines in
value judged to be other-than-temporary on available-for-sale securities are
reported as investment income or investment expense. The cost of securities sold
is based on the specific identification method.

Concentration of Credit Risk: The Company performs ongoing credit evaluations of
its customers' financial condition and generally requires no collateral from its
customers. The Company maintains reserves for potential credit losses, and such
losses have historically been within management's expectations.

The Company invests its excess cash in deposits with major banks and in money
market and short-term debt securities of companies with strong credit ratings
from a variety of industries. These securities generally mature within 365 days
and, therefore, bear minimal risk. The Company has not experienced any material
losses on its investments. The Company, by Corporate policy, limits the amount
of credit exposure to any one issuer and to any one type of investment.

Inventories: Inventories are carried at the lower of cost or market. Cost is
determined on a first-in, first-out basis.

Property, Plant, and Equipment: Property, plant, and equipment are carried at
cost, less accumulated depreciation and amortization computed on a straight-line
basis over the lesser of the estimated useful lives of the assets (generally
three to ten years for machinery, equipment, furniture, and leasehold
improvements; and twenty-five years for buildings) or the lease term.

Purchased Intangibles: Purchased intangible assets were acquired as a result of
acquisitions recorded using the purchase method of accounting. Under this method
of accounting, the purchase price is allocated to assets acquired and
liabilities assumed based on their estimated fair values at consummation. The
Company's purchased intangible assets include completed technology, work force
in place, a supply agreement, and customer lists. The assets are being amortized
over their estimated useful lives, which range from three to ten years. The
accumulated

28


amortization at March 31, 1997 and 1996, was $60.9 million and $39.8 million,
respectively. Intangible assets are reviewed for impairment whenever events or
circumstances indicate an impairment might exist, or at least annually.

Warranty Expense: The Company generally warrants its products against defects
for a period of one to five years. A provision for estimated future costs
relating to warranty expense is recorded when products are shipped and revenue
recognized.

Advertising Expense: The Company accrues for co-operative advertising as the
related revenue is earned, and other advertising expense is recorded as
incurred. Advertising expense for the years ended March 31, 1997, 1996 and 1995,
was $35.2 million, $25.1 million, and $19.8 million, respectively.

Stock-Based Compensation: Effective April 1, 1996, the Company adopted Statement
of Financial Accounting Standards No. 123, "Accounting for Stock-Based
Compensation" (SFAS No. 123), which was effective for fiscal years beginning
after December 15, 1995. SFAS No. 123 establishes the financial accounting and
reporting standards for stock-based compensation plans. The Company elected to
continue accounting for stock-based employee compensation plans in accordance
with Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to
Employees" and related Interpretations (APB Opinion No. 25), as SFAS No. 123
permits, and to follow the pro forma net income, pro forma earnings per share,
and stock-based compensation plan disclosure requirements set forth in SFAS No.
123.

Risks and Uncertainties: The Company's business entails a number of risks. As is
typical in the disk drive industry, a significant portion of the Company's
customer base is concentrated with a small number of OEMs, and the Company is
not able to predict whether there will be any significant change in the demand
for its customers' products. The loss of any one of the Company's more
significant customers could have a material adverse effect on the Company's
results of operations. A limited number of disk and tape drive storage products
make up a significant majority of the Company's sales, and due to rapid
technological change in the industry, the Company's future depends on its
ability to develop and successfully introduce new products. Quantum utilizes a
third party, MKE, to manufacture a substantial majority of the products it
sells. The Company relies on MKE's ability to bring new products rapidly to
volume production and to meet stringent quality standards. MKE manufactures
Quantum's drives in Japan, Singapore, and Ireland. If MKE were unable to satisfy
Quantum's production requirements, the Company would not have an alternative
source to meet the demand for its products without substantial delay and
disruption to its operations. The actual results with regard to warranty
expenditures could have a material unfavorable impact on the Company if the
actual rate of unit failure or the cost to repair a unit is greater than what
the Company has used in estimating the warranty expense accrual. In addition,
the Company is also subject to legal proceedings and claims that arise in the
ordinary course of its business (refer to Note 13 of the Notes to Consolidated
Financial Statements).


Note 2: Financial Instruments

Available-for-sale securities


The following is a summary of available-for-sale securities, all of which are
classified as cash equivalents:

The difference between the amortized cost of available-for-sale securities and
fair value was immaterial at March 31, 1997 and 1996, and therefore no gross
unrealized gains or losses were recorded in shareholders' equity. The estimated
fair value of available-for-sale securities is based on market quotations. There
were no sales of available-for-sale securities in fiscal 1997 or 1996. At March
31, 1997, the average available-for-sale portfolio duration was approximately 15
days and the securities had maturities of 90 days or less.

Derivative financial instruments

Trading
During the periods covered by the financial statements, the Company has not used
any derivative financial instrument for trading purposes.

Interest Rate Management
During the periods covered by the financial statements, the Company has not used
derivative financial instruments to manage interest rate fluctuations related to
interest-bearing investments or borrowings.

Foreign Exchange - Firm Commitments & Anticipated Transactions
During the periods covered by the financial statements, the Company has not
utilized derivative financial instruments to manage either foreign currency firm
commitments or anticipated foreign currency transactions.

Foreign Exchange - Asset and Liability Management
During the periods covered by the financial statements, the Company utilized
foreign currency forward exchange contracts to manage the effects of foreign
currency remeasurement arising from certain assets and liabilities denominated
in a foreign currency. The gains and losses from market rate changes on these
contracts, which are intended to offset the gains and losses on certain foreign
currency denominated assets and liabilities, are recorded monthly in other
income.

The following is a summary of foreign currency forward contracts held for asset
and liability management purposes:

March 31,
------------------------------------
(In millions except for forward rates) 1997 1996
------------------------------------

U.S. dollar notional amount $27.0 $36.2
U.S. dollar equivalent $26.5 $34.5
Fair value $ 0.5 $ 1.7

The fair values for foreign currency forward contracts represent the difference
between the contracted forward rate and the quoted fair value of the underlying
yen at the balance sheet dates. The Company generally does not require
collateral from the counterparties to foreign currency forward contracts.

Carrying amount and fair values of financial instruments

The carrying values of cash and cash equivalents and accounts receivable are
deemed to be reasonable estimates of their fair values.


The estimated fair value of the Company's borrowings are summarized as follows:

March 31,
--------------------------------------------------------------------------
(In millions) 1997 1996
--------------------------------------------------------------------------
Carrying Fair Carrying Fair
Amount Value Amount Value
------ ----- ------ -----


Convertible subordinated debt $ 241.4 $ 433.8 $ 374.3 $ 387.7

Term loan 56.3 56.3 - -
Mortgage loan 41.8 41.3 - -
Equipment loan 13.9 15.2 18.0 18.0


The fair values for the convertible subordinated debt are based on the quoted
market price at the balance sheet dates. Fair values for the revolving credit
agreement and term loan approximate their carrying amounts, since interest rates
on these borrowings are adjusted periodically to reflect market interest rates.
The fair value of the mortgage and equipment loans were based on the estimated
present value of the remaining payments, utilizing risk-adjusted market interest
rates of similar instruments at the balance sheet date.

Note 5: Credit Agreements

The Company has a one-year $85 million unsecured Letter of Credit facility with
certain banks to issue standby letters of credit to MKE and its affiliates,
which expires in September 1997. As of March 31, 1997, there was no outstanding
balance under this letter of credit facility.


Note 6: Long-Term Debt

The Company has a senior credit facility that includes a $325 million revolving
credit line that expires in September 1998, and in August 1996, the Company
obtained a $75 million term loan under this credit facility. The revolving
credit line is governed by a borrowing base of eligible accounts receivable and
inventory. The senior credit facility is secured by all the Company's domestic
assets and 66% of the Company's ownership of certain of its subsidiaries.
Borrowings under the senior credit facility, at the option of the Company, bear
interest at either LIBOR plus a margin or a base rate with option periods of one
to six months.

The term loan began to amortize on December 31, 1996, and the outstanding $56.3
million balance as of March 31, 1997, continues to amortize over six remaining
quarterly payments. As of March 31, 1997, outstanding borrowings under the
revolving credit line were $110 million with a weighted average interest rate of
7.8%. The maximum amount outstanding during the year under the senior credit
facility was $385 million and the average amount outstanding for the year was
approximately $281 million. The total weighted average interest rates on the
bank debt for the years ended March 31, 1997 and 1996, were 7.7% and 8.3%,
respectively. Financial covenants related to the senior credit facility include
but are not limited to an operating profitability ratio, quick ratio, and
leverage ratio. The Company's debt agreement currently prohibits the Company
from paying dividends while the debt is outstanding.

In February 1996, the Company issued approximately $241 million of 5%
convertible subordinated notes (the "Notes") in a privately placed offering. The
Notes are due March 1, 2003, and are subordinated to all existing and future
senior indebtedness of the Company. Each Note is convertible at the option of
the holder into the Company's common stock at a conversion price of $11.16 per
share. The Notes are redeemable at the Company's option on or after March 3,
1998, and prior to March 3, 2000, under certain conditions related to the price
of the Company's common stock. Subsequent to March 3, 2000, the Notes are
redeemable at the Company's option at any time. Redemption prices range from
103.571% of the principal to 100% at maturity.

In March 1996, the Company entered into an $18 million term loan facility to
finance certain capital equipment. The facility amortizes over three years at a
fixed interest rate of 7.63% and payments are made on a quarterly basis.
The facility is secured by specified capital equipment.

32


In September 1996, the Company entered into a $42 million mortgage financing
related to certain domestic facilities at an effective interest rate of
approximately 10.1%. The term of the mortgage is 10 years, with monthly payments
based on a 20-year amortization period, and a balloon payment at the end of the
10-year term. The debt is secured by specified real estate.

In December 1996, the Company called for redemption of all of the Company's
outstanding 6 3/8% convertible subordinated debentures due April 1, 2002, at a
redemption price of $1,057.38 per $1,000 principal amount of debenture. At the
time of the call for redemption, approximately $93 million of these debentures
were outstanding. Holders of the debentures exercised their option to convert
debentures held into 10,216,964 shares of the Company's common stock at a
conversion price of approximately $9.08 per share. The Company redeemed $40,000
of principal amount of debentures for $42,295 which includes redemption premium
and accrued interest.

Payments required on long-term debt outstanding at March 31, 1997, are $44.2
million in fiscal 1998, $136 million in fiscal 1999, $2.7 million in fiscal
2000, $1.1 million in fiscal 2001, $1.3 million in fiscal 2002 and $36.6 million
thereafter.


Note 7: Redeemable Preferred Stock and Acquisition of Minority Interest In
Quantum Peripherals Colorado, Inc.

In February 1997, the company issued 90,000 shares of Redeemable Convertible
Participating Series B Preferred Stock in conjunction with the acquisition of
the 19% minority ownership interest in Quantum Peripherals Colorado, Inc.
("QPC"), a consolidated subsidiary involved in the development and manufacture
of recording heads. The Series B preferred shares are manditorily redeemable for
$111.11 per share, plus declared but unpaid dividends, in the event of voluntary
or involuntary liquidation, dissolution, change in control, or sale of all or
substantially all the assets of the Company. Holders of the Series B preferred
shares have liquidation preference senior to that of holders of the Company's
common stock. Each Series B preferred share will convert to two shares of the
Company's common stock, adjusted for certain common stock actions, upon the
earlier to occur of 1) the Company's common stock closing at $35.00 per share,
adjusted for certain common stock actions, 2) April 1, 1999, or 3) written
notice of the holders of a majority of outstanding Series B preferred shares.
The holders of Series B preferred shares ratably participate on an
as-if-converted basis with holders of common stock, in declared cash and in-kind
dividends. The Series B preferred shares are nonvoting.

The QPC minority ownership interest was acquired in exchange for $3.4 million
and the issuance of the 90,000 shares of Series B preferred shares, which were
valued at $3.9 million as of the issuance date. The acquisition was recorded
using the purchase method of accounting. Under this method of accounting, the
purchase price is allocated to assets acquired and liabilities assumed based on
their estimated fair values at consummation. The entire purchase price was
assigned to purchased intangibles that were assigned a four-year life.


Note 8: Stock Incentive Plans

Long-Term Incentive Plan: The Company has a Long-Term Incentive Plan (the
"Plan") that provides for the issuance of stock options, stock appreciation
rights, stock purchase rights, and long-term performance awards (collectively
referred to as "options"). The Plan has available and reserved for issuance 11.8
million shares and allows for an annual increase in the number of shares
available for issuance, subject to a limitation. Available for grant as of March
31, 1997, were 1,240,000 shares. Options under the Plan expire no later than ten
years from the grant date and generally vest over four years. Restricted stock
granted under the Plan generally vests over two to three years. In fiscal 1997
and 1996, the Company recorded compensation expense of $1,916,000 and $899,000,
respectively, related to restricted stock granted pursuant to stock purchase
rights under the Plan. The number of shares of restricted stock granted under
the Plan were 354,290 and 596,000, in fiscal 1997 and 1996, respectively, at a
weighted average exercise price of $.01.

33


Stock Option Plans: The Company has Stock Option Plans (the "Plans") under which
an aggregate of 6.4 million shares of common stock have been reserved for future
issuance. Options under the Plans are granted at prices determined by the Board
of Directors, but at not less than the fair market value, and accordingly no
compensation accounting has been required at the original date of grant. Options
currently expire no later than ten years from the grant date and generally vest
ratably over one to four years. At March 31, 1997, options with respect to
600,000 shares were available for grant.

Expiration dates ranged from May 30, 1997 to March 19, 2007 for options
outstanding at March 31, 1997. Prices for options exercised during the two-year
period ended March 31, 1997, ranged from $0.01 to $13.94. Proceeds received by
the Company from exercises are credited to Common Stock and capital in excess of
par value.

34


Stock Purchase Plan: The Company has an employee stock purchase plan (the
"Purchase Plan") that allows for the purchase of stock at 85% of fair market
value at the date of grant or the exercise date, whichever value is less. The
Purchase Plan is qualified under Section 423 of the Internal Revenue Code. Of
the 17 million shares authorized to be issued under the plan, 1,574,000 shares
were available for issuance at March 31, 1997. Employees purchased 3,216,000 and
2,676,000 shares under the Purchase Plan in fiscal 1997 and 1996, respectively.
The weighted average exercise price of stock purchased under the Purchase Plan
was $5.41 and $5.98 in fiscal 1997 and 1996, respectively.

Pro forma information: Pro forma information regarding net income and earnings
per share is required by SFAS No. 123. This information is required to be
determined as if the Company had accounted for its employee stock options
(including shares issued under the Long-Term Incentive Plan, Stock Option Plans,
and the Stock Purchase Plan, collectively called "options") granted subsequent
to March 31, 1995, under the fair value method of that statement.


The fair value of options granted in fiscal 1997 and 1996 reported below has
been estimated at the date of grant using a Black-Scholes option pricing model
with the following weighted average assumptions:

Long-Term Incentive Plan and
Stock Option Plans Stock Purchase Plan
--------------------------------------- ---------------------------------------
Fiscal 1997 Fiscal 1996 Fiscal 1997 Fiscal 1996
- ---------------------------- ------------------- ------------------- ------------------- -------------------

Option life (in years) 2.9 2.8 0.8 1.1
Risk-free interest rate 6.0% 6.7% 6.0% 6.7%
Stock price volatility .50 .50 .50 .50
Dividend yield - - - -


The Black-Scholes option pricing model was developed for use in estimating the
fair value of traded options that have no vesting restrictions and are fully
transferable. In addition, option valuation models require the input of highly
subjective assumptions, including the expected stock price volatility. Because
the Company's options have characteristics significantly different from those of
traded options, and because changes in the subjective input assumptions can
materially affect the fair value estimate, in the opinion of management, the
existing models do not necessarily provide a reliable single measure of the fair
value of the options.


The following is a summary of weighted average grant date fair values:

Weighted Average Grant Date Fair Value
-----------------------------------------------
Fiscal 1997 Fiscal 1996
-------------------------- --------------------

Options granted under the Long-Term Incentive
Plan and Stock Option Plans $ 3.67 $ 3.30

Restricted stock granted under the Long-Term
Incentive Plan $14.28 $10.70

Shares granted under the Stock Purchase Plan $ 2.46 $ 2.66

35


For purposes of pro forma disclosures, the estimated fair value of the options
is amortized to expense over the option's vesting period. The Company's pro
forma net income and earnings per share follows:

Year Ended March 31
------------------------------------
1997 1996
------------------ -----------------
Net income (In thousands) $ 132,678 $ (101,600)
========= ===========

Net income (loss) per share:
Primary $ 1.08 $ (0.98)
========= ===========
Fully diluted $ 0.91 $ (0.98)
========= ===========


Since pro forma compensation cost relates to all periods over which the options
vest, the initial impact on pro forma net income may not be representative of
option expense in subsequent years, when the effect of the amortization of
multiple awards would be reflected.


Note 9: Common Stock and Shareholder Rights Plan

Effective April 28, 1997, the number of authorized shares of Common Stock
increased to 500,000,000 from 150,000,000.

On May 13, 1997, Quantum declared a two-for-one stock split to be effected as a
stock dividend of one share of Common Stock for every one share of Common Stock
outstanding. New stock was issued in June 1997, to shareholders of record on May
27, 1997. The share and per share amounts reported in the fiscal 1997
Consolidated Financial Statements reflect retroactive recognition of the
two-for-one stock split.

The Company has a shareholder rights plan (the "Rights Plan") that provides
existing shareholders with the right to purchase 1/200 preferred share for each
common share held in the event of certain changes in the Company's ownership.
The Rights Plan may serve as a deterrent to takeover tactics that are not in the
best interests of shareholders.


Note 10: Restructuring and Other Expenses

In the fourth quarter of fiscal 1996, the Company recorded a restructuring
charge of $209 million, pre-tax, associated with the transition of its
high-capacity products manufacturing to MKE. As part of the transition, the
Company discontinued its manufacture of these products and completed the
shut-down of the related facilities in fiscal 1997. The related manufacturing
work force was terminated in fiscal 1997. The Company closed, sold, or disposed
of certain high-capacity manufacturing facilities and equipment located in
Penang, Malaysia; and Milpitas, California, which as of March 31, 1996, were
carried at a fair value of approximately $30 million, net of estimated cost to
dispose. Facilities sold included the manufacturing building in Malaysia, which
was sold in the second quarter of fiscal 1997.

The restructuring charge provided for costs associated with employee termination
benefits for over 2,200 employees that were associated with the high-capacity
product manufacturing process; the difference between the carrying value and
estimated fair value on disposal of high-capacity manufacturing property and
equipment; and incremental impairments in the carrying value of certain
high-capacity product inventories and losses on supplier commitments arising
directly from the decision to stop manufacturing, as follows:

Employee termination benefits $ 10
Write-down of capital assets to fair value 45
Write-down of inventories to net realizable value and
losses on supplier commitments 144
Other exit costs 10
----
$209
====

The activities contemplated in the transition and related restructuring reserve
have been substantially completed at March 31, 1997, without a material change
in the estimated cost of such activities. There remains $5,983,000 of accrued
exit costs at March 31, 1997.


Note 11: Savings and Investment Plan

Substantially all of the regular domestic employees are eligible to make
contributions to the Company's 401(k) savings and investment plan. The Company
matches a percentage of the employee's contributions and may also make
additional discretionary contributions to the plan. Prior to October 1, 1994,
all of the Company's matching contributions were discretionary. Company
contributions were $5.2 million in fiscal 1997, $4.0 million in fiscal 1996, and
$1.1 million in fiscal 1995.

For financial reporting purposes, the Company has provided a valuation allowance
for certain deferred tax assets that are expected to reverse over a 15-year
period. The Company believes that the valuation allowance is needed to reduce
the deferred tax asset to an amount that is more likely than not to be realized.
The valuation allowance decreased approximately $1.1 million from fiscal 1995 to
fiscal 1996.

Pretax income from foreign operations was $241.2 million, $124.3 million, and
$113.6 million for the years ended March 31, 1997, 1996, and 1995, respectively.
U.S. taxes have not been provided for unremitted foreign earnings of $248.4
million. The residual U.S. tax liability if such amounts were remitted would be
approximately $61 million.

Note 13: Litigation

The Company and certain of its current and former officers and directors have
been named as defendants in two class-action lawsuits, one filed on August 28,
1996, in the Superior Court of Santa Clara County, California, and one filed on
August 30, 1996, in the U.S. District Court for the Northern District of
California. The plaintiffs in both class actions purport to represent a class of
all persons who purchased the Company's common stock between February 26, 1996,
and June 13, 1996. The complaints allege that the defendants violated various
federal securities laws and California statutes by concealing and/or
misrepresenting material adverse information about the Company and that
individual defendants sold shares of the Company's stock based on material
nonpublic information.

In the state court action, on October 23, 1996, the Company filed a demurrer
requesting dismissal of the state action, and on November 21, 1996, the Company
moved for a determination that the action not be permitted to proceed as a class
action. The court sustained the demurrer in large part, and deferred ruling on
the motion for determination that the action not proceed as a class action.
Plaintiffs recently amended their complaint. Defendants' demurrer to the amended
complaint, defendants' motion that the action not proceed as a class action, and
plaintiffs' motion for class certification are all set for hearing on June 5,
1997.

In the federal action, plaintiffs' motion for appointment of lead plaintiff was
granted on April 4, 1997. Defendants recently filed a motion to dismiss the
complaint. The motion to dismiss is currently set for hearing on July 8, 1997.

Certain of the Company's current and former officers and directors have also
been named as defendants in a derivative lawsuit, which was filed on November 8,
1996, in the Superior Court of Santa Clara County, California. The derivative
complaint is based on factual allegations substantially similar to those alleged
in the class-action lawsuits. On April 14, 1997, the court granted defendants'
demurrer, and dismissed the complaint in its entirety, with leave to amend.
Plaintiffs have not yet filed an amended complaint.

The Company believes that the pending actions are without merit and intends to
defend against them vigorously. Nevertheless, litigation is subject to inherent
uncertainties and thus there can be no assurance that these suits will be
resolved favorably to the Company or will not have a material adverse effect on
the Company's financial position, results of operations, or liquidity.

The Company is also subject to other legal proceedings and claims that arise in
the ordinary course of its business. While management currently believes the
amount of ultimate liability, if any, with respect to these actions will not
materially affect the financial position, results of operations, or liquidity of
the Company, the ultimate outcome of any litigation is uncertain. Were an
unfavorable outcome to occur, the impact could be material to the Company.

Note 14: Commitments

The Company leases its present facilities under non-cancelable operating lease
agreements for periods of up to 15 years. Some of the leases have renewal
options ranging from one to ten years and contain provisions for maintenance,
taxes, or insurance.

Rent expense was $26.4 million, $29.7 million, and $18.8 million for the years
ended March 31, 1997, 1996, and 1995, respectively.

Future minimum lease payments under operating leases are as follows:

(In thousands)
Year ended March 31,

1998 $ 23,570
1999 23,071
2000 20,056
2001 15,257
2002 13,098
Thereafter 56,314
----------
Total future minimum lease payments $ 151,366
==========

The Company licenses certain data storage technology that is used in its
products. As of March 31, 1997, future payments for the licensing of certain
data storage technology are as follows: $8.0 million, $5.7 million, $5.7
million, and $5.7 million to be paid in the fiscal years ending March 31, 1998,
1999, 2000, and 2001, respectively.

Quantum, operating in a single business segment, designs, develops, and markets
information storage products, including high-performance, high-quality 3.5-inch
hard disk drives; economical high-capacity 5.25-inch hard disk drives; half-inch
cartridge tape drives and libraries; tape drive-related products; and solid
state disk drives. The half-inch cartridge tape drives and libraries and solid
state disk drives are manufactured by the Company. Quantum is also involved in
the design, development, and manufacture of MR recording heads that are used in
the Company's hard disk drives, which are manufactured by the Company's
exclusive manufacturing partner, MKE (refer to Note 18 of the Notes to
Consolidated Financial Statements).

41


As a percentage of total sales in fiscal year 1997, 1996, and 1995, half-inch
cartridge tape drives and related product sales were 13%, 7% and 3%,
respectively. The rest of the sales resulted primarily from shipments of hard
disk drives.

One major customer accounted for 11%, 12%, and 16% of consolidated sales in
fiscal 1997, 1996, and 1995, respectively. In addition, another customer
accounted for 11% of consolidated sales in fiscal 1997, and another accounted
for 11% and 12% of consolidated sales in fiscal 1996 and 1995, respectively.

A significant percentage of the Company's sales is made to customers in non-U.S.
locations and a majority of the Company's products is manufactured by MKE in
Japan, Singapore, and Ireland. Quantum also operates a repair facility in
Malaysia, a repair and distribution center in Ireland, and a manufacturing plant
in Indonesia. As a result, the Company is subject to risks associated with
foreign operations, such as obtaining governmental permits and approvals,
currency exchange fluctuations, currency restrictions, political instability,
labor problems, trade restrictions, and changes in tariff and freight rates.

Export sales for fiscal 1997, 1996, and 1995 were less than 10% of consolidated
sales.

Information on operations by geographic area is presented in the preceding
tables. Transfers between geographic areas are accounted for at amounts that are
generally above cost and are eliminated in the consolidated financial
statements. Identifiable assets are those assets that can be directly associated
with a particular geographic location. Operating income (loss) by geographic
area does not include an allocation of general corporate expenses.


Note 16: Acquisition of Businesses from Digital Equipment Corporation

In fiscal 1995, Quantum acquired the Hard Disk Drive, Heads, and Tape Drives
Businesses of the Storage Business Unit of Digital Equipment Corporation ("the
Acquired Businesses"), in a transaction accounted for as a purchase. The
operating results of the Acquired Businesses have been included in the
consolidated statement of operations from the date of acquisition.

The purchase price which was finalized in the second quarter of fiscal 1996, was
$349.5 million.

A recap of finalized purchase price allocation follows (in millions):

Inventories $142.1
Property and equipment 103.2
Intangible assets 106.1
Accrual for exit costs (34.9)
Other assets/liabilities, net (34.2)
Purchased research and development 67.2
------
$349.5
======

Intangible assets include $79.5 million of completed technology and an aggregate
of $26.6 million for work force in place, a supply agreement, and customer
lists. Completed technology and work force in place were assigned four- year
lives, while the customer base was assigned a ten-year life. The supply
agreement was assigned a life equal to the terms of the contractual agreement.
Intangible asset amortization totaled $24.0 million, $26.5 million, and $13.4
million in fiscal 1997, 1996, and 1995, respectively. The decline in the
intangible asset amortization from fiscal year 1996 to 1997 reflected the fiscal
1997 write-off of high-capacity product manufacturing work force intangible
assets against the high-capacity product manufacturing transition restructuring
reserve recorded in fiscal 1996 (refer to Note 10 of the Notes to Consolidated
Financial Statements).

The accrual for exit costs included only those direct costs related to exiting
facilities and operations in Colorado acquired from Digital and did not include
any costs related to modifications of the previous Quantum business.

42


The components of the exit activities were as follows:

(In millions)

Non-cancelable lease commitments after closure
and costs to "make new" as required by the lease $11.4
Reduction in force 7.7
Retention bonuses 4.5
Write-off of capital assets resulting from closures 9.3
Other 2.0
-----
$34.9
=====

The activities contemplated in the $34.9 million accrual for exit costs have
been completed at March 31, 1997, without a material change in the estimated
cost of such activities.

The $67.2 million allocated to purchased research and development was expensed
in fiscal 1995 as required under generally accepted accounting principles.

The unaudited pro forma combined condensed results of operations of the Company
for the 12 months ended March 31, 1995, had the acquisition occurred at the
beginning of the period and that eliminate the non-recurring charges, are as
follows:

(In thousands except per share data)
Year Ended
Pro Forma March 31, 1995
- ------------------------------------------------- ------------------

Net sales $3,790,769
Net income (loss) $ 75,877
Net income (loss) per share:
Primary $ 0.80
Fully diluted $ 0.65

The unaudited pro forma results for the 12 months ended March 31, 1995, exclude
the effects of the charge for purchased research and development and other in
merger costs of $73 million, as such amounts are non-recurring. The pro forma
results for the twelve months ended March 31, 1995, reflect intangible asset
amortization, depreciation of acquired fixed assets, amortization of loan fees,
and interest expense on the new debt related to the acquisition.

The unaudited pro forma information is presented for illustrative purposes only
and is not necessarily indicative of the operating results that would have
occurred had the transaction been completed at the beginning of the period
indicated, nor is it necessarily indicative of future operating results.

(i) The results of operations for the fourth quarter in fiscal 1996 included
the effect of a $209 million charge related to the transition of
manufacturing for the Company's high-capacity products to MKE (refer to
Note 10 of the Notes to Consolidated Financial Statements).




Note 18. Subsequent Events - Unaudited

MKE/Quantum Joint Venture

On May 1, 1997, the Company agreed to sell a controlling interest in its
recording heads operations (RHO) to MKE. RHO designs, develops, and manufactures
MR recording heads used in the Company's disk drive products. The sale will be
achieved through MKE acquiring a 51% interest in a new joint venture (JV) entity
that will hold the operations, assets, and certain liabilities of RHO. The RHO
assets to be transferred to the JV are primarily comprised of inventory,
equipment, and intangibles. These assets had an approximately $206 million
aggregate carrying value at March 31,1997, and the liabilities totaled
approximately $24 million. In addition, the JV will lease certain premises from
Quantum, and RHO employees will become employees of the joint venture.

MKE and the Company will share pro rata in the capital requirements, if any, of
the JV. The Company plans to continue to utilize all of the recording heads
manufactured by the JV in its disk drive products.

Unaudited Pro Forma Information

Giving effect to the above-noted sale transaction as if it had occurred on April
1, 1996, the pro forma effect on the Company's consolidated balance sheet at
March 31, 1997, would not have been significant, and net income for fiscal 1997
would have been approximately $180 million or $1.23 per share, fully diluted.
This unaudited pro forma information is intended for information purposes only
and is not necessarily indicative of the future results of operations of the JV
or the results of the Company that would have occurred had the JV arrangement
been in effect for the full fiscal year presented.
