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
<PAGE>

         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.

                                                                               3

         Quantum  DLT 7000.  Mass  production  of the DLT 7000 began in December
         1996.  The Quantum DLT 7000  provides  data storage and  retrieval  for
         demanding  data back-up,  archive,  and on-line  storage  applications.
         Assuming data compression,  this tape drive achieves a transfer rate of
         over 10 MB per  second and a  formatted  capacity  of 70 GB.  This tape
         drive provides  significant  performance  and capacity  advantages over
         other drives in its class.

         Quantum DLTTM Autoloaders:

         Quantum  DLT   2500XT/2700XT/4500/4700.   Quantum  DLT  half-inch  tape
         autoloaders  are  five- and  seven-cartridge  subsystems  designed  for
         high-capacity data backup  applications in the computer systems market.
         Ranging in capacity from 150 to 280 GBs, each autoloader consists of an
         elevator mechanism that provides random or sequential  cartridge access
         between  a tape  drive and  cartridge  magazines.  All are  appropriate
         table-top   solutions  or  can  be  configured  into  standard  19-inch
         equipment racks.

         Quantum DLTstorTM Tape Library:

         High-Performance  Cartridge Tape  Mini-Libraries,  the Quantum  DLTstor
         tape library subsystem is designed for use with Quantum's family of DLT
         7000,  4000 and 2000XT tape drives.  Equipped with two  seven-cartridge
         magazines  and up to  three  drives,  the  DLTstor  product  family  is
         available in native capacities of 490, 280 and 210 GBs.

         Quantum DLTtapeTM III, IIIXT,IV:

         The Quantum DLTtapeTM family of half-inch  cartridge tapes are designed
         and  formulated   specifically   for  Quantum  DLTTM  tape  drives  and
         libraries.  The capacity of the half-inch  cartridge  tapes is up to 35
         GBs, or 70 GBs in compressed  mode. By combining  both solid and liquid
         lubricants  in the tape binder  system,  tape and head wear are reduced
         while repelling  airborne  particles that could affect  read/write head
         performance.  In addition,  by using a uniform  particle shape, a dense
         binding system, a smooth coating surface, and a specially selected base
         film,  Quantum's  half-inch  cartridge  tapes take advantage of shorter
         wavelength  recording schemes to ensure read  compatibility with future
         generations of DLT brand tape drives.

         Quantum ESP5000 Series,  ESP3000 Series and  ESP3000/ESP5000  Table Top
         Series Solid State Disks:

         Quantum's solid state disks (SSDs) significantly  improve the execution
         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

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.

                                                                               8

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
information  regarding  the joint  venture,  refer to Part I, Item 1,  Strategic
Developments - MKE/Quantum  Recording Heads Joint Venture;  and Part II, Item 8,

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
<PAGE>

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
<PAGE>

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
<PAGE>

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
<PAGE>

      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
<PAGE>

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
<PAGE>

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
<PAGE>

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
<PAGE>

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).

<PAGE>

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:

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.

                                                                              30

</TABLE>

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
<PAGE>

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
<PAGE>

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.

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

(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.

</TABLE>

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

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:

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:

                                                                              36

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.

taxes currently payable as shown above by $11.1 million,  $8.5 million, and $1.6
million in fiscal 1997, 1996, and 1995, respectively. Such benefits are credited
to capital in excess of par value when realized.

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.

                                                                              38

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.

                                                                              39

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
<PAGE>

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

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  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:

   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

(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.

                                                                              44

                        Delaware General Corporation Law)


         QUANTUM CORPORATION, a corporation existing under the laws of the State
of  Delaware  (the  "Corporation"),  by  Michael  A.  Brown,  President  of  the
Corporation,  and Richard L. Clemmer, Secretary of the Corporation,  DOES HEREBY
CERTIFY as follows:

         1. That pursuant to Section 4 of the  Certificate of  Incorporation  of
the  Corporation,  the  Corporation is authorized to issue  4,000,000  shares of
Preferred  Stock,  par value $.01 per share,  and the Board of  Directors of the
Corporation is expressly  authorized to fix, to the extent  permitted by law and
said Section 4, the distinctive terms and  characteristics of any and all series
of Preferred Stock.

         2. That the Board of Directors of the Corporation, at a meeting thereof
held on January 31, 1997, duly adopted the following resolutions authorizing the
issuance  of a series of the  Corporation's  Preferred  Stock,  and  fixing  the
designations,  preferences and other rights and qualifications,  limitations and
restrictions thereof as follows:

         "WHEREAS,   the  Board  of  Directors  of  Quantum   Corporation   (the
"Corporation") is authorized,  within the limitations and restrictions stated in
the Certificate of Incorporation of the Corporation, to provide by resolution or
resolutions for the issuance of shares of its preferred stock par value $.01 per
share (the  "Preferred  Stock"),  and by filing a certificate of designations in
the manner  prescribed under the laws of the State of Delaware,  to fix or alter
the dividend rights, dividend rate, conversion rights, voting rights, rights and
terms of redemption  (including  sinking fund  provisions),  redemption price or
prices,  and  liquidation  preferences of any wholly unissued class or series of
Preferred  Stock,  and  the  number  of  shares  of any  such  series,  and  the
designation thereof, or any of them; and

         WHEREAS, the Board of Directors of the Corporation desires to authorize
and fix the  terms of a series  of  Preferred  Stock  and the  number  of shares
constituting such series;

         NOW, THEREFORE,  BE IT RESOLVED that a series of Preferred Stock on the
terms and with the provisions set forth below is hereby authorized:

                  1.  Designation.  The Preferred  Stock created and  authorized
         hereby shall be designated as the "Series B Preferred  Stock, par value
         $.01 per share" (the "Series B Preferred Stock").  The number of shares
         constituting  the Series B  Preferred  Stock  shall be ninety  thousand
         (90,000) and no more.

                                       1.

<PAGE>

                  2. Rank. The Series B Preferred  Stock shall,  with respect to
         rights on liquidation,  dissolution or winding up of the affairs of the
         Corporation,  rank prior to the common stock,  par value $.01 per share
         (the  "Common  Stock"),  of the  Corporation  and all  other  series of
         Preferred Stock of the Corporation (the Common Stock and all such other
         series  of   Preferred   Stock  are  herein   referred  to  as  "Junior
         Securities").  The Series B Preferred Stock shall be subordinate to any
         bank debt.

                  3.  Liquidation  Preference.  In the event of any voluntary or
         involuntary  liquidation,  dissolution,  change in control  (as defined
         below)  or  sale  of  all  or  substantially  all  the  assets  of  the
         Corporation,  the  holders of shares of Series B  Preferred  Stock then
         outstanding  shall  be  entitled  to be paid out of the  assets  of the
         Corporation  available for  distribution to its  stockholders an amount
         per share  equal to the sum of one  hundred  eleven  dollars and eleven
         cents ($111.11),  plus an amount equal to declared but unpaid dividends
         on each such share of Series B  Preferred  Stock,  before  any  payment
         shall be made or any assets  distributed  to the  holders of any of the
         Junior  Securities.  Except  as  provided  in the  preceding  sentence,
         holders  of  Series B  Preferred  Stock  shall not be  entitled  to any
         distribution in the event of liquidation,  dissolution or winding up of
         the affairs of the  Corporation.  If the assets of the  Corporation are
         not sufficient to pay in full the liquidation  payments  payable to the
         holders of the outstanding shares of the Series B Preferred Stock, then
         the holders of all such shares  shall share  ratably in such payment or
         distribution   of  assets.   A  "change  of  control"  shall  mean  any
         consolidation  or  merger  of the  Corporation  with or into any  other
         Corporation  or  other  entity  or  person,   or  any  other  corporate
         reorganization,   in  which  the   stockholders   of  the   Corporation
         immediately prior to such consolidation,  merger or reorganization, own
         less  than  fifty  percent  (50%)  of the  Corporation's  voting  power
         immediately after such consolidation, merger or reorganization.

                  4.  Conversion.  Each share of Series B Preferred  Stock shall
         convert into such number of fully paid, non-assessable shares of Common
         Stock as shall  equal  the then  current  Conversion  Rate (as  defined
         below)  upon the  earlier to occur of (i) the close of  business on the
         date the  Current  Fair Market  Value (as  defined  below) per share of
         Common Stock equals or exceeds the Conversion Price (as defined below),
         (ii) April 1, 1999 or (iii) such date as specified  by written  consent
         or  agreement  of the  holders  of a majority  of the then  outstanding
         shares of Series B Preferred  Stock after the date such written consent
         or  agreement is received by the  Corporation.  The  "Conversion  Rate"
         shall initially be one (1) and the  "Conversion  Price" shall initially
         be seventy dollars  ($70.00),  and each shall be adjusted in accordance
         with  Section 5. For the  purpose  of any  computation  hereunder,  the
         "Current  Fair  Market  Value" of a share of  Common  Stock on any date
         shall be deemed to be the  closing  price per share of Common  Stock on
         the Trading Day (as defined below)  immediately prior to such date. The
         closing  price for each day shall be the last sale price,  regular way,
         or, in case no such sale takes  place on such day,  the  average of the
         closing bid and asked  prices,  regular way, in either case as reported

         the Common  Stock is not listed or admitted to trading on any  national
         securities exchange or reported on the Nasdaq National Market, the last
         quoted price or, if not so quoted,  the average of the high bid and low

         date the  Common  Stock is not  quoted  by any such  organization,  the
         average  of  the  closing  bid  and  asked  prices  as  furnished  by a
         professional  market maker making a market in the Common Stock selected

         shall mean a day on which the principal national securities exchange on
         which the Common Stock is listed or admitted to trading is open for the
         transaction  of  business  or,  if the  Common  Stock is not  listed or
         admitted to trading on any  national  securities  exchange,  a day upon
         which trading  occurred on the Nasdaq National Market or, if the Common
         Stock is not listed on the Nasdaq National Market, any day other than a
         Saturday, a Sunday, or a day on which banking institutions in the State
         of California are authorized or obligated by law or executive  order to

         Shares  of  Series  B  Preferred  Stock  shall  be  convertible  at the
         principal office of the Corporation or the office of any transfer agent
         or at such other  office or offices,  if any, as the Board of Directors
         may designate.  In order to convert shares of Series B Preferred  Stock
         into shares of Common Stock,  the holder thereof shall surrender at any
         office hereinabove  mentioned the certificate or certificates  therefor
         duly endorsed or assigned to the  Corporation  or in blank and free and
         clear of all liens,  charges and encumbrances,  and give written notice
         to the Corporation at said office designating the number of such shares
         to be so converted  and, if any of the shares are to be registered in a
         name or names other than that in which the shares of Series B Preferred
         Stock surrendered are registered, specifying the name or names in which
         such shares are to be registered.  The  Corporation  shall,  as soon as
         practicable thereafter, issue and deliver at such office to such holder
         of Series B  Preferred  Stock,  or to the  nominee or  nominees of such
         holder,  a  certificate  or  certificates  for the  number of shares of
         Common Stock to which such holder shall be entitled as aforesaid.  Such
         conversion shall be deemed to have been made  immediately  prior to the
         close of business on the date of such  surrender of the share of Series
         B Preferred Stock to be converted,  and the person or persons  entitled
         to receive the shares of Common  Stock  issuable  upon such  conversion
         shall be treated for all  purposes  as the record  holder or holders of
         such shares of Common Stock as of such date.

                           (a) Stock Splits, Subdivisions, etc. In the event the
                  Corporation  should at any time or from time to time after the
                  date of the first  issuance of Series B Preferred  Stock fix a
                  record date for the  effectuation of a split or subdivision of
                  the outstanding  shares of Common Stock, or the  determination
                  of holders of Common  Stock  entitled to receive a dividend or
                  other  distribution  payable  in  additional  shares of Common
                  Stock,  or other  securities  or  rights  convertible  into or
                  entitling   the  holder   thereof  to  receive   directly   or
                  indirectly,  additional  shares of Common  Stock  (hereinafter
                  referred to as "Common Stock Equivalents")  without payment of
                  any  consideration by such holder for the additional shares of
                  Common Stock or the Common Stock  Equivalents  (including  the
                  additional  shares of Common Stock issuable upon conversion or
                  exercise  thereof),  then, as of such record date (or the date
                  of such  dividend  distribution,  split or  subdivision  if no
                  record  date is  fixed),  (i) the  Conversion  Price  shall be
                  appropriately  decreased  so  that  (A)  the  product  of  the
                  Conversion  Price  immediately  preceding such record date (or
                  the date of such dividend  distribution,  split or subdivision
                  if no record date is fixed) multiplied by the number of shares
                  of  Common  Stock and  Common  Stock  Equivalents  outstanding
                  immediately  preceding  such  record date (or the date of such
                  dividend distribution,  split or subdivision if no record date
                  is fixed)  equals (B)  product of the  Conversion  Price as so
                  decreased  multiplied  by the number of shares of Common Stock
                  and Common Stock Equivalents outstanding immediately following
                  such record date (or the date of such  dividend  distribution,
                  split or subdivision if no record date is fixed), and (ii) the
                  Conversion Rate shall be  appropriately  increased so that (A)
                  the product of the Conversion Rate as so increased  multiplied
                  by the  number  of shares of  Series B  Preferred  Stock  then
                  outstanding  equals (B) such number of shares of Common  Stock
                  as would have been obtained following such record date (or the
                  date of such dividend distribution, split or subdivision if no
                  record  date is fixed)  had the  shares of Series B  Preferred
                  Stock then  outstanding  converted  to shares of Common  Stock
                  immediately  preceding  such  record date (or the date of such
                  dividend distribution,  split or subdivision if no record date
                  is fixed) at the then current Conversion Rate.

                           (b) Stock  Combinations.  If the  number of shares of
                  Common  Stock  outstanding  at any time  after the date of the
                  first  issuance of Series B Preferred  Stock is decreased by a
                  combination of the outstanding  shares of Common Stock,  then,
                  following  the  record  date  of  such  combination,  (i)  the
                  Conversion   Price  shall  be   appropriately   increased   by
                  multiplying the then Conversion Price by the fraction obtained
                  by  dividing   (A)  the  number  of  shares  of  Common  Stock
                  outstanding  immediately preceding such record date by (B) the
                  number  of  shares of  Common  Stock  outstanding  immediately
                  following such record date, and (ii) the Conversion Rate shall
                  be appropriately  decreased by multiplying the then Conversion
                  Rate by the  fraction  obtained by dividing  (A) the number of
                  shares of Common Stock outstanding immediately

                                       4.
<PAGE>

                  following  such  record  date by (B) the  number  of shares of
                  Common Stock  outstanding  immediately  preceding  such record
                  date.

                           (c) Recapitalizations. If at any time or from time to
                  time there  shall be a  recapitalization  of the Common  Stock
                  (other than a  subdivision,  combination  or merger or sale of
                  assets transaction provided for elsewhere in this Section 5 or
                  Section  3),  provisions  shall be made so that the holders of
                  the Series B Preferred  Stock shall  thereafter be entitled to
                  receive upon  conversion  of the Series B Preferred  Stock the
                  number of shares of stock or other  securities  or property of
                  the Corporation or otherwise to which a holder of Common Stock
                  deliverable  upon conversion  would have been entitled on such
                  recapitalization.  In any such  case,  appropriate  adjustment
                  shall be made in the  application  of the  provisions  of this
                  Section 5 with  respect  to the  rights of the  holders of the
                  Series B Preferred Stock after the recapitalization to the end
                  that the provisions of this Section 5 (including adjustment of
                  the Conversion Price and Conversion Rate then in effect) shall
                  be applicable after that event as nearly  equivalent as may be
                  practicable.

                           (d)  No  Fractional  Shares  and  Certificate  as  to
                  Adjustments.

                                    (i) No  fractional  shares  shall be  issued
                           upon the  conversion of any share or shares of Series
                           B Preferred  Stock and the number of shares of Common
                           Stock to be issued  shall be rounded  to the  nearest
                           whole  share.  Whether or not  fractional  shares are
                           issuable upon such conversion  shall be determined on
                           the basis of the  total  number of shares of Series B
                           Preferred  Stock the holder is at the time converting
                           into Common  Stock and the number of shares of Common
                           Stock  issuable upon such aggregate  conversion.  The
                           Corporation  shall,  in  lieu of  issuing  fractional
                           shares,  pay to each Series B Preferred  Stockholder,
                           in cash,  the amount equal to the Current Fair Market
                           Value  of a  share  of  Common  Stock  on the  day of
                           conversion  multiplied  by the fraction of a share of
                           Common   Stock  to  which  such  Series  B  Preferred
                           Stockholder  would  have  been  entitled  but for the
                           provisions of this Section 5(d)(i).

                                    (ii) Upon the occurrence of each  adjustment
                           or   readjustment   of  the   Conversion   Price  and
                           Conversion  Rate of Series B Preferred Stock pursuant
                           to this Section 5, the  Corporation,  at its expense,
                           shall   promptly    compute   such    adjustment   or
                           readjustment  in accordance with the terms hereof and
                           prepare  and  furnish  to each  holder  of  Series  B
                           Preferred  Stock a  certificate  setting  forth  such
                           adjustment or readjustment  and showing in detail the
                           facts upon which such  adjustment or  readjustment is
                           based.

                           (e) Minimal Adjustments;  Rounding.  No adjustment in
                  the  Conversion  Rate or  Conversion  Price  shall be required
                  unless such  adjustment  would require an increase or decrease
                  of at least 1% in the Conversion Rate or Conversion  Price, as
                  the case may be; provided, however, that any adjustments which
                  by reason of this  Section  5(e) are not  required  to be made
                  shall be carried  forward  and taken into  account in the next
                  subsequent  adjustment.  All calculations under this Section 5
                  shall be made to the nearest one  one-thousandth of a share of
                  Series B  Preferred  Stock  (rounded up in the event of a five
                  ten-thousandth  of a  share),  in the  case of the  Conversion
                  Rate,  or to the  nearest  cent  (rounded up in the event of a
                  half-cent), in the case of the Conversion Price.

                           (f)  Reservation of Stock  Issuable Upon  Conversion.
                  The Corporation  shall at all times reserve and keep available
                  out of its  authorized  but unissued  shares of Common  Stock,
                  solely for the  purpose of  effecting  the  conversion  of the
                  shares of the Series B  Preferred  Stock,  such  number of its
                  shares  of  Common  Stock  as  shall  from  time  to  time  be
                  sufficient to effect the conversion of all outstanding  shares
                  of the Series B Preferred Stock; and if at any time the number
                  of authorized but unissued shares of Common Stock shall not be
                  sufficient to effect the  conversion  of all then  outstanding
                  shares of the Series B  Preferred  Stock,  in addition to such
                  other  remedies  as shall be  available  to the holder of such
                  Series B  Preferred  Stock,  the  Corporation  will  take such
                  corporate  action as may,  in the opinion of its  counsel,  be
                  necessary to increase its  authorized  but unissued  shares of
                  Common  Stock to such number of shares as shall be  sufficient
                  for such purposes, including, without limitation,  engaging in
                  best efforts to obtain the requisite  stockholder  approval of
                  any necessary amendment to these articles.

                           (g)  Status  of Common  Stock  Upon  Conversion.  All
                  shares of Common Stock which may be issued in connection  with
                  the conversion provisions set forth herein will, upon issuance
                  by  the  Corporation,   be  validly  issued,  fully  paid  and
                  nonassessable, not subject to any preemptive or similar rights
                  and free from all taxes, liens or charges with respect thereto
                  created or imposed by the Corporation.

                           (h) Transfer  Taxes.  The  Corporation  shall pay all
                  documentary,  stamp or other  transactional taxes attributable
                  to the issuance or delivery of shares of capital  stock of the
                  Corporation   upon  conversion  of  any  shares  of  Series  B
                  Preferred Stock; provided, however, that the Corporation shall
                  not be  required  to pay any  taxes  which may be  payable  in
                  respect to any  transfer  involved in the issuance or delivery
                  of any  certificate  for such shares in a name other than that
                  of the Series B Preferred Stockholder in respect of which such
                  shares of Series B Preferred Stock are being issued.

                                       6.

                           holders of shares of Series B  Preferred  Stock shall
                           be deemed  given if  deposited  in the United  States

                  6.  Voting  Rights.  Holders  of shares of Series B  Preferred
         Stock will not be entitled  to vote,  except as  otherwise  required by
         law,  with  respect  to  any  matters   submitted  to  a  vote  of  the
         stockholders.

                  7.  Dividends.  The  holders  of record of Series B  Preferred
         Stock shall be entitled to receive  ratably  with the holders of record
         of shares of Common Stock on an as-if-converted  basis, such dividends,
         payable in cash or otherwise (other than dividends payable in shares of
         Common  Stock or Common  Stock  Equivalents,  to which the  holders  of
         record of shares of Series B Preferred Stock shall not be entitled), as
         may be declared thereon by the Board of Directors from time to time out
         of assets or funds of the Corporation legally available therefor.

                  8. Reacquired  Shares.  Any shares of Series B Preferred Stock
         purchased  or  otherwise  acquired  by the  Corporation  in any  manner

         and  restrictions  on issuance set forth herein,  in the Certificate of

         StorageTek  hereby  represents  and  warrants to Quantum that as of the
date hereof:

         3.1  Organization  and  Standing.  StorageTek  is  a  corporation  duly
organized,  validly existing and in good standing under the laws of the State of
Delaware.  StorageTek has all requisite corporate power and authority to execute
and deliver this Agreement and the Letter Agreement,  to sell the Shares, and to
carry out the provisions of this Agreement and the Letter Agreement.  StorageTek
is duly  qualified and is authorized to do business and is in good standing as a
foreign  corporation in all  jurisdictions in which the nature of its activities
and  of  its  properties  (both  owned  and  leased)  makes  such  qualification
necessary,  except for those  jurisdictions  in which failure to do so would not
have a Material  Adverse Effect on StorageTek.  For purposes of this  Agreement,
"Material  Adverse  Effect"  means a  material  adverse  effect  on the  assets,
business, operations or financial condition of the business entity.


                                       2.
<PAGE>

         3.2  Power  and  Authorization.  All  corporate  action  on the part of
StorageTek,   its  directors,   officers  and  stockholders  necessary  for  the
authorization of this Agreement and the Letter Agreement, the performance of all
obligations of StorageTek  hereunder and thereunder and the sale and delivery of
the Shares pursuant hereto has been taken or will be taken prior to the Closing.
The Agreement and the Letter  Agreement,  when executed and  delivered,  will be
valid and binding obligations of StorageTek enforceable in accordance with their
respective  terms,  except as  limited  by  applicable  bankruptcy,  insolvency,
reorganization,  moratorium  or  other  laws of  general  application  affecting
enforcement of creditors'  rights.  The sale of the Shares to Quantum is not and
will not be subject to any  preemptive  rights or rights of first  refusal  that
have not been properly waived or complied with.

         3.3 No Violation or Conflict.  The execution,  delivery and performance
of  this  Agreement  and  the  Letter  Agreement  and  the  consummation  of the
transaction  contemplated  hereby and thereby by  StorageTek do not and will not
violate, conflict with, result in a breach of, or constitute a default or result
in or permit any acceleration of any obligation under, (a) any law, ordinance or
governmental  rule  or  regulation  to  which  StorageTek  is  subject,  (b) any
judgment,  order, writ, injunction,  decree or award of any court, arbitrator or
governmental  or regulatory  official,  body or authority which is applicable to
StorageTek,  (c)  its  certificate  of  incorporation  or  by-laws,  or (d)  any
mortgage, indenture,  agreement,  contract,  commitment, lease, license or other
instrument or document,  oral or written,  to which StorageTek is a party, or by
which any of the Shares may be bound, except where a waiver with respect thereto
has been obtained.

         3.4 Governmental Authorization. The execution, delivery and performance
by StorageTek of this  Agreement and the Letter  Agreement  does not require any
action by or in respect  of, or filing  with,  any  governmental  body,  agency,
official or  authority  other than:  (a) such filings as have been made prior to
the  Closing;  and  (b)  such  post-closing  filings  as may be  required  under
applicable  state  securities  laws,  which  will be  timely  filed  within  the
applicable periods therefor.

         3.5  Information.   StorageTek  confirms  that  it  has  had  the  full
opportunity  to make all inquiries and receive all  information  it desires with
respect to the business,  operations and financial  affairs of QPC (in regard to
StorageTek's  sales of the Shares) and the  business,  operations  and financial
affairs of Quantum (in regards to StorageTek's purchase of the Quantum Preferred
Shares).  StorageTek  has had the  opportunity  to ask  questions of and receive
answers from  Quantum and its  management.  StorageTek  has all  information  it
considers  necessary or appropriate for deciding  whether to execute and perform
this Agreement. StorageTek has been represented by its own counsel in connection
with the transactions set forth herein.

         3.6 Litigation.  There is no action, suit,  proceeding or investigation
pending or, to StorageTek's knowledge,  currently threatened against StorageTek,
that  questions  the validity of this  Agreement or the Letter  Agreement or the
right of StorageTek to enter into this Agreement or the Letter Agreement,  or to
consummate the transaction  contemplated  hereby,  nor is StorageTek  aware that
there is any basis for the foregoing.

                                       3.
<PAGE>

         3.7 Title to Shares; No Encumbrance.  Immediately prior to the purchase
and sale  contemplated  in Section 1 hereof,  StorageTek  owns and will own,  of
record and  beneficially,  good, valid and marketable title to the Shares,  free
and clear of any and all liens, security interests,  mortgage,  pledge,  charge,
claim or other encumbrance of any nature whatsoever ("Liens").  Upon delivery of
the Shares by  StorageTek  to Quantum at the  Closing,  and upon  payment of the
Purchase  Price  therefor,  good and  valid  title to such  Shares  will pass to
Quantum,  free and clear of all Liens,  other than  those  arising  from acts of
Quantum or its  affiliates.  Other  than this  Agreement  and the  Stockholders'
Agreement  by  and  among  Digital  Equipment  Corporation  (as  predecessor  to
Quantum), StorageTek, and Rock Mountain Magnetics, Inc. (the prior name of QPC),
dated  August  19,  1992 (the  "Stockholders'  Agreement"),  the  Shares are not
subject to any voting trust agreement or other contract, arrangement, commitment
or  understanding,  including but not limited to those  restricting or otherwise
relating to the voting, dividend rights or disposition of the Shares. Except for
the  Shares,  StorageTek  does not own,  directly  or  indirectly,  of record or
beneficially,  any  securities  of QPC,  and  StorageTek  has no  right of first
refusal,  right of  co-sale,  contractual  preemptive  right,  or other right to
acquire  any  unissued  securities  or other  property  of QPC or Quantum or any
issued and outstanding securities of QPC held by Quantum.

         3.8 Investment Representations. StorageTek understands that the Quantum
Preferred  Shares have not been registered  under the Securities Act of 1933, as
amended (the  "Securities  Act").  StorageTek also  understands that the Quantum
Preferred  Shares are being  offered  and sold  pursuant  to an  exemption  from
registration  contained in the  Securities  Act based in part upon  StorageTek's
representations  contained in this Agreement.  StorageTek  hereby represents and
warrants as follows:

                  (a) StorageTek Bears Economic Risk. StorageTek has substantial
experience  in  evaluating  and  investing  in  transactions  of  securities  in
companies  similar to Quantum so that it is capable of evaluating the merits and
risks of its  investment  in Quantum  and has the  capacity  to protect  its own
interests.   StorageTek   must  bear  the  economic  risk  of  this   investment
indefinitely  unless the Quantum Preferred Shares are registered pursuant to the
Securities  Act, or an exemption  from  registration  is  available.  StorageTek
understands  that Quantum has no present  intention of  registering  the Quantum
Preferred Shares or the shares of common stock,  $0.01 par value,  issuable upon
conversion of the Quantum  Preferred Shares the ("Quantum  Conversion  Shares").
StorageTek also  understands  that there is no assurance that any exemption from
registration  under the  Securities  Act will be  available  and  that,  even if
available,  such  exemption  may not allow  StorageTek  to  transfer  all or any
portion of the Quantum  Preferred Shares or Quantum  Conversion  Shares or under
the circumstances, in the amounts or at the times StorageTek might propose.

                  (b) Acquisition  for Own Account.  StorageTek is acquiring the
Quantum Preferred Shares and the Quantum  Conversion Shares for StorageTek's own
account for investment only, and not with a view towards their distribution.

                                       4.
<PAGE>

                  (c)  Investment  Experience.  StorageTek  represents  that  by
reason  of  its,  or of its  management's,  business  or  financial  experience,
StorageTek has the capacity to protect its own interests in connection  with the
transactions contemplated in this Agreement.

                  (d) Restricted Securities.  StorageTek acknowledges and agrees
that the Quantum  Preferred  Shares and Quantum  Conversion  Shares must be held
indefinitely unless they are subsequently registered under the Securities Act or
an exemption from such registration is available.

                  (g)  Legends.   Each  certificate   representing  the  Quantum
Preferred  Shares and Quantum  Conversion  Shares  shall be stamped or otherwise
imprinted with a legend  substantially  similar to the following (in addition to
any legend  required  under  applicable  state  securities  laws or as  provided
elsewhere in this Agreement):

                           THE  SECURITIES  REPRESENTED  HEREBY  HAVE  NOT  BEEN
                           REGISTERED  UNDER  THE  SECURITIES  ACT OF 1933  (THE
                           "ACT")  AND MAY  NOT BE  OFFERED,  SOLD OR  OTHERWISE
                           TRANSFERRED, ASSIGNED, PLEDGED OR HYPOTHECATED UNLESS
                           AND UNTIL  REGISTERED UNDER THE ACT OR UNLESS QUANTUM
                           HAS  RECEIVED AN OPINION OF COUNSEL  SATISFACTORY  TO
                           QUANTUM AND ITS COUNSEL THAT SUCH REGISTRATION IS NOT
                           REQUIRED.

Quantum shall be obligated to reissue  promptly  unlegended  certificates at the
request of any holder  thereof if the holder  shall have  obtained an opinion of
counsel  (which  counsel may be counsel to  Quantum)  reasonably  acceptable  to
Quantum  to the  effect  that the  securities  proposed  to be  disposed  of may
lawfully be so disposed of without  registration,  qualification or legend.  Any
legend endorsed on an instrument  pursuant to applicable  state  securities laws
and the  stop-transfer  instructions  with respect to such  securities  shall be
removed  upon  receipt  by  Quantum  of an  order  of the  appropriate  blue sky
authority authorizing such removal.

SECTION 4.  REPRESENTATIONS AND WARRANTIES OF QUANTUM.

Quantum,   its   directors,   officers  and   stockholders   necessary  for  the

of  this  Agreement  and  the  Letter  Agreement  and  the  consummation  of the
transaction  contemplated  hereby  and  thereby  by  Quantum do not and will not
violate, conflict with, result in a breach of, or constitute a default or result
in or permit any acceleration of any obligation under, (a) any law, ordinance or
governmental  rule or regulation to which Quantum is subject,  (b) any judgment,
order,  writ,  injunction,   decree  or  award  of  any  court,   arbitrator  or
governmental  or regulatory  official,  body or authority which is applicable to
Quantum,  (c) its certificate of incorporation or by-laws,  or (d) any mortgage,
indenture,  agreement,  contract, commitment, lease, license or other instrument
or  document,  oral or  written,  to which  Quantum is a party,  or by which the
Quantum Preferred Shares or the Quantum  Conversion Shares may be bound,  except
where a waiver with respect thereto has been obtained.

         4.5 Governmental Authorization. The execution, delivery and performance
by Quantum of this Agreement does not require any action by or in respect of, or
filing with, any governmental  body,  agency,  official or authority other than:

post-closing  filings as may be required under applicable state securities laws,
which will be timely filed within the applicable periods therefor.

         4.6 Litigation.  There is no action, suit,  proceeding or investigation
pending or, to Quantum's  knowledge,  currently  threatened against Quantum that
questions the validity of this


                                       6.
<PAGE>

Agreement  or the  Letter  Agreement  or the right of Quantum to enter into this

foregoing.

         4.7  Investment  Representations.  Quantum  confirms  that  as the  81%
stockholder  of QPC, it has all of the  information  it requires with respect to
the business,  management and financial affairs of QPC. Quantum understands that
