                     % CONVERTIBLE SUBORDINATED NOTES DUE 2003
 
    HMT Technology Corporation ("HMT" or the "Company") hereby offers 4,000,000
shares of Common Stock (the "Common Stock Offering"), and $150,000,000 of   %
Convertible Subordinated Notes due 2003 (the "Note Offering"). The   %
Convertible Subordinated Notes due 2003 (the "Notes") are convertible into
shares of Common Stock at any time through maturity, unless previously redeemed
or repurchased, at a conversion price of $   per share, subject to adjustment in
certain events. Prior to the Note Offering, there has been no public trading
market for the Notes. The Notes are expected to be traded on the
over-the-counter market. The Company's Common Stock is traded on the Nasdaq
National Market under the symbol "HMTT." On May 24, 1996, the last reported sale
price for the Common Stock on the Nasdaq National Market was $26.00 per share.
 
    Interest on the Notes is payable on         and         , commencing
          , 1996. The Notes are not redeemable at the option of the Company
prior to           , 1998. At any time on or after such date, the Notes will be
redeemable on at least 20 but not more than 60 days' notice, at the option of
the Company, in whole or in part at any time, initially at     % and thereafter
at prices declining to 100% of the principal amount of the Notes at maturity,
together with accrued and unpaid interest to the redemption date, provided, that
the Company may not redeem the Notes prior to             , 1999 unless the
closing price of the Common Stock on the principal stock exchange or market on
which the Common Stock is then quoted or admitted to trading equals or exceeds
150% of the conversion price for at least 20 trading days within a period of 30
consecutive trading days ending on the fifth trading day prior to the date the
notice of redemption is first mailed to the holders of the Notes. In the event
of a Designated Event (as defined), each holder may require the Company to
repurchase all or a portion of such holder's Notes at 100% of the principal
amount thereof, plus accrued and unpaid interest. The Notes are unsecured and
are subordinated to all existing and future Senior Indebtedness (as defined) of
the Company. At March 31, 1996, the Company had outstanding approximately $8.5
million that would have constituted Senior Indebtedness. See "Description of the
Notes."
 
    The Common Stock Offering and the Note Offering are referred to collectively
as the "Offerings." Neither the closing of the Common Stock Offering nor the
closing of the Note Offering is conditioned on the closing of the other
offering.
                             ---------------------
 
   
     THE COMMON STOCK AND THE NOTES OFFERED HEREBY INVOLVE A HIGH DEGREE OF
RISK. UPON THE COMPLETION OF THE OFFERINGS AND BASED ON SHARES OUTSTANDING AT
MARCH 31, 1996, DIRECTORS, OFFICERS AND THEIR AFFILIATES WILL OWN APPROXIMATELY
62% OF THE OUTSTANDING COMMON STOCK AND WILL CONTROL MOST CORPORATE ACTIONS. SEE

                                    SUMMARY
 
     The following summary is qualified in its entirety by the more detailed
information, including "Risk Factors," and the Consolidated Financial Statements
and Notes thereto, appearing elsewhere in this Prospectus. This Prospectus is
being used by the Company to offer 4,000,000 shares of Common Stock and $150
million principal amount of the Notes. Neither the closing of the Common Stock
Offering nor the closing of the Note Offering is conditioned on the closing of
the other offering. This Prospectus contains forward-looking statements which
involve risks and uncertainties. The Company's actual results may differ
significantly from the results discussed in the forward-looking statements.
Factors that might cause such a difference include, but are not limited to,
those discussed in "Risk Factors."
 
                                  THE COMPANY
 
   
     HMT is an independent supplier of high-performance thin film disks for
high-end, high-capacity hard disk drives, which in turn are used in high-end
personal computers ("PCs"), network servers and workstations. The disks
currently being shipped by the Company are primarily for disk drives with
storage capacities ranging from 1.6 to 9 gigabytes (using three to 12 disks),
and all have coercivity levels of 1900 Oe or higher. Since March 1994, the
Company has focused on addressing the needs of this high-end, high-capacity
segment of the disk drive market. HMT believes that its recent operating results
reflect its success in meeting these needs and that its future growth and
success depend on its ability to continue to develop and market products that
enable its customers to produce high-performance disk drives for high-end data
storage applications. The Company provides a range of magnetic density points
(coercivities), glide heights and disk thicknesses to match the design and
performance requirements of each particular customer. The Company currently
focuses all of its production capacity on 3 1/2-inch disks, although it is
capable of producing disks in other standard form factors. In fiscal 1996, HMT
sold its disks to Maxtor Corporation, Western Digital Corporation, Micropolis
Corporation, Quantum Corporation, Iomega Corporation and Hewlett-Packard
Company. The Company has also recently begun shipping disks to Samsung
Electronics Company Limited.
    
 
     Market demand for disks and disk drives is growing rapidly, stimulated by
demand for new computers, upgrades to existing computers and the growing use of
sophisticated network servers. The combined demand from the PC and server
markets has resulted in strong growth in unit shipments of disk drives, which in
turn has stimulated the growth of the thin film disk market. According to Trend
Focus, the number of thin film disks produced in 1993 was 134 million, was 256
million in 1995 and is projected to reach 416 million in 1997. The worldwide
market for thin film disks is estimated to have been $3.3 billion in 1995.
 
     The most significant technological challenges facing disk manufacturers
today are associated with market demand for increased storage capacity and
durability. An effective implementation of thin film technology to meet these
challenges must address various performance-related characteristics, including
magnetics, glide height, durability and static friction ("stiction"). HMT
focuses on providing value added technological solutions that meet the demands
of the high-end, high-capacity disk drive market. The Company develops,
manufactures and sells technologically advanced products designed to provide
improved performance, principally through achieving higher coercivities and
lower glide heights. The Company seeks to be a supplier to disk drive
manufacturers with a proven record for technological leadership because these
customers have the greatest ability to fully exploit the value of
technologically superior disks.
 
     HMT believes that its internally developed proprietary manufacturing
processes and state-of-the-art equipment, to which it has made proprietary
modifications, combined with its extensive expertise, currently provide HMT with
a technological advantage over competing independent thin film disk
manufacturers. Particularly important to the Company's success are its unique
tribology approach, its commitment to developing disks for drives utilizing new
head technology and its ability to produce high-coercivity disks using
non-precious metal alloys.
 
     The key elements of HMT's strategy are as follows: establish and maintain
leadership in high-end product technology; develop collaborative relationships
with leading head manufacturers and disk drive manufacturers; develop advanced
manufacturing processes to support volume production; maintain strict quality
control of manufacturing process; and expand manufacturing capacity.
 
     The Company has recently announced plans to construct a new production
facility at its Fremont, California site, in which it plans to install up to 16
additional production scale sputtering lines. The Company has also recently
acquired an aluminum substrate manufacturing facility and related equipment
located in Eugene, Oregon, and has announced plans to enlarge that facility in
order to increase substrate production and to add nickel plating and polishing
capability.

(2) The ratio of earnings to fixed charges is computed by dividing (x) the sum
    of income before provision for income taxes, extraordinary items and fixed
    charges, less capitalized interest, by (y) fixed charges. Fixed charges
    consist of interest on all indebtedness, amortization of debt expense and
    discount or premium relating to indebtedness, including a one-time charge
    related to debt extinguishment of $1.1 million. Earnings were inadequate to
    cover fixed charges for all periods prior to fiscal 1996. The deficiencies
    of earnings were approximately $22.0 million, $17.6 million, $17.4 million
    and $8.9 million for fiscal 1992, 1993, 1994 and 1995, respectively.

                                  RISK FACTORS
 
     In addition to the other information in this Prospectus, the following risk
factors should be considered carefully in evaluating the Company and its
business before purchasing shares of the Common Stock offered hereby. This
Prospectus contains forward-looking statements which involve risks and
uncertainties. The Company's actual results may differ significantly from the
results discussed in the forward-looking statements. Factors that might cause
such a difference include, but are not limited to, those discussed below.
 
HISTORY OF OPERATING LOSSES
 
     The Company experienced operating losses for its fiscal years ending March
31, 1994 and 1995 of $11.3 and $2.0 million, respectively. Although the Company
has improved its operating results since its new management team was assembled
and has achieved an operating profit in five of the past six quarters, there can
be no assurance that the Company will be able to maintain profitability in the
future. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations."
 
FLUCTUATIONS IN OPERATING RESULTS
 
     The Company's operating results historically have been, and may continue to
be, subject to significant quarterly and annual fluctuations. For example,
during the eight quarters ended March 31, 1996, the Company's net sales, gross
profit (loss) and net income (loss) ranged from $14.8 million, $(2.6) million
and $(6.7) million, respectively, for the three months ended March 31, 1995 to
$65.0 million, $27.2 million and $11.6 million for the three months ended March
31, 1996. As a result, the Company's operating results in any quarter may not be
indicative of its future performance. Factors affecting operating results
include: market acceptance of new products; timing of significant orders;
changes in pricing by the Company or its competitors; timing of product
announcements by the Company, its customers or its competitors; order
cancellations, modifications and quantity adjustments and shipment
reschedulings; changes in product mix; manufacturing yields; the level of
utilization of the Company's production capacity; increases in production and
engineering costs associated with initial manufacture of new products; and
changes in the cost of or limitations on the availability of materials. The
impact of these and other factors on the Company's revenues and operating
results in any future period cannot be forecasted with certainty. The Company's
expense levels are based, in part, on its expectations as to future revenues.
Because the Company's sales are generally made pursuant to purchase orders that
are subject to cancellation, modification, quantity reduction or rescheduling on
short notice and without significant penalties, the Company's backlog as of any
particular date may not be indicative of sales for any future period, and such
changes could cause the Company's net sales to fall below expected levels. If
revenue levels are below expectations, operating results are likely to be
materially adversely affected. Net income, if any, and gross margins may be
disproportionately affected by a reduction in net sales because a
proportionately smaller amount of the Company's expenses varies with its
revenues. See "-- Dependence on Suppliers" and "Management's Discussion and
Analysis of Financial Condition and Results of Operations."
 
     The Company derives substantially all of its net sales from the sale of
thin film disks to a small number of customers. The Company typically supplies
disks in volume for a limited number of disk drive products at any one time, and
these products have an extremely short life cycle. Due to the rapid
technological change and frequent development of new disk drive products, it is
common in the industry for the relative mix of customers and products to change
rapidly, even from quarter to quarter. Generally, new products have higher
average selling prices than more mature products. Therefore, the Company's
ability to introduce new products in a timely fashion is an important factor in
its continued success. Moreover, manufacturing yields and production capacity
utilization impact the Company's operating results. New products often have
lower manufacturing yields and are produced in lower quantities than more mature
products. Manufacturing yields generally improve as the product matures and
production volumes increase. Manufacturing yields also vary depending on the
complexity and uniqueness of product specifications. The ability to adjust
manufacturing procedures to reduce costs and improve manufacturing yields and
productivity during a product's life is
 
                                        7
<PAGE>   10
 
limited, and many adjustments can only be implemented in connection with new
product introductions or upgrades. Small variations in manufacturing yields and
productivity can have a significant impact on operating results. Furthermore,
because the thin film disk industry is capital intensive and requires a high
level of fixed costs, operating results are also extremely sensitive to changes
in volume. Substantial advance planning and commitment of financial and other
resources is necessary for expansion of manufacturing capacity, while the
Company's sales are generally made pursuant to purchase orders that are subject
to cancellation, modification, quantity reductions or rescheduling without
significant penalties. The impact of any of the foregoing factors could have a
material adverse effect on the Company's business, operating results and
financial condition.
 
DEPENDENCE ON A LIMITED NUMBER OF CUSTOMERS; LENGTHY SALES CYCLE
 
     During fiscal 1995 and 1996, the Company shipped most of its thin film
disks to four customers: Maxtor Corporation ("Maxtor"), Western Digital
Corporation ("Western Digital"), Hewlett-Packard Corporation ("Hewlett Packard")
and Micropolis Corporation ("Micropolis"). Aggregate shipments to Maxtor,
Western Digital, Hewlett-Packard and Micropolis represented 73.7%, 5.9%, 0.0%
and 11.2%, respectively, of net sales in fiscal 1995 and 40.5%, 35.8%, 3.7% and
9.1%, respectively, of net sales during fiscal 1996. There are a relatively
small number of disk drive manufacturers, and the Company expects that its
dependence on a few customers will continue in the future. Loss of or a
reduction in orders from one or more of the Company's customers could result in
a substantial reduction in net sales. Because many of the Company's expense
levels are based, in part, on its expectations as to future revenues, decreases
in net sales may result in a disproportionately greater negative impact on
operating results. The Company's success will therefore depend on the success of
its key customers. For example, in fiscal 1994 the Company's operating results
were adversely affected by operating difficulties experienced by the Company's
then largest customer. One or more of the Company's customers could develop or
expand their ability to produce thin film disks internally and, as a result,
could reduce the level of purchases or cease purchasing from the Company or
could sell thin film disks in competition with the Company. For example, one of
the Company's customers, Western Digital, manufactures thin film disks for its
own use and an affiliate of another customer, Maxtor, has recently announced
plans to do so. There has also been a trend toward consolidation in the disk
drive industry, which the Company expects to continue. For example, in February
1996, two leading disk drive manufacturers, Seagate Technology, Inc. ("Seagate")
and Conner Peripherals, Inc., combined to form the world's largest disk drive
manufacturing company. If any of the Company's customers or competitors were to
combine and reduce suppliers and competitive product lines, the Company's
business, operating results and financial condition could be materially
adversely affected. See "Business -- Customers, Sales and Support."
 
   
     The Company has generally sold its products to customers pursuant to
purchase orders and similar short-term arrangements. In June 1996, the Company
entered into a long-term supply agreement with Maxtor covering the supply of
disks to Maxtor over the next five years. While this agreement contemplates a
significant increase in the purchases of disks by Maxtor from current levels, it
is subject to a number of conditions and qualifications; and there can be no
assurance that Maxtor will in fact remain a significant customer during the term
of the agreement.
    
 
     Qualifying thin film disks for incorporation into a new disk drive product
requires the Company to work extensively with the customer and the customer's
other suppliers to meet product specifications. Therefore, customers often
require a significant number of product presentations and demonstrations, as
well as substantial interaction with the Company's senior management, before
making a purchasing decision. Accordingly, the Company's products typically have
a lengthy sales cycle, which can range from six to 12 months, during which the
Company may expend substantial financial resources and management time and
effort with no assurance that a sale will result.
 
INTENSE COMPETITION
 
     The market for the Company's products is highly competitive, and the
Company expects competition to continue in the future. Certain of the Company's
competitors have significantly greater
 
                                        8
<PAGE>   11
 
financial, technical and marketing resources than the Company. There can be no
assurance that in the future the Company will be able to develop and manufacture
products on a timely basis with the quality and features necessary in order to
remain competitive. Competitors in the thin film disk industry fall into three
groups: U.S. non-captive manufacturers, Japan-based manufacturers and U.S.
captive manufacturers. Historically, each of these groups has supplied
approximately one-third of the worldwide thin film disk unit output. The
Company's primary U.S. non-captive competitors are Akashic Memories Corporation,
a subsidiary of Kubota, Inc. ("Akashic"), Komag, Incorporated ("Komag") and
StorMedia Incorporated ("StorMedia"). Japan-based competitors include Fuji
Electric Company, Ltd. ("Fuji"), Mitsubishi Kasei Corporation ("Mitsubishi"),
Showa Denko K.K. ("Showa Denko") and Hoya Corporation ("Hoya"). In addition,
U.S. captive manufacturers, which include certain computer manufacturers, as
well as disk drive manufacturers such as Seagate, an affiliate of Maxtor and
Western Digital, manufacture disks or plan to manufacture disks for their
internal use as part of their vertical integration programs. These companies
could increase their internal production and reduce or cease purchasing from
independent disk suppliers such as the Company. In the event of an oversupply of
disks, these customers are likely to utilize their internal capacity prior to
purchasing disks from independent suppliers such as the Company. Moreover, while
captive manufacturers have, to date, sold only nominal quantities of thin film
disks in the open market, there can be no assurance that such companies will not
in the future do so in direct competition with the Company. Furthermore, there
can be no assurance that other current and potential customers will not acquire
or develop capacity to produce thin film disks for internal use. Any such
changes could have a material adverse effect on the Company's business,
operating results and financial condition. Announcement or implementation of any
of the following by the Company's competitors could have a material adverse
effect on the Company's business, operating results and financial condition:
changes in pricing, product introductions, increases in production capacity,
changes in product mix and technological innovation. Specifically, the thin film
disk industry is characterized by intense price competition. The Company has
experienced pricing pressures in the past, and there can be no assurance that
the Company will not experience increased price competition in the future.
Pricing pressure has included, and may in the future include, demands for
discounts, long-term supply commitments and extended payment terms. Any increase
in price competition could have a material adverse effect on the Company's
business, operating results and financial condition. See
"Business -- Competition."
 
     The Company believes that certain of its competitors are currently engaged
in substantial efforts to increase disk manufacturing capacity in light of the
apparent imbalance between current levels of demand for disks and existing
industry capacity. These efforts should result in significant additional
capacity in the industry within the next one to two years. To the extent that
these efforts result in industry capacity in excess of levels of demand, the
Company could experience increased levels of competition, which could have a
material adverse effect on the Company's business, operating results and
financial condition.
 
DEPENDENCE ON INTENSELY COMPETITIVE AND CYCLICAL HARD DISK DRIVE INDUSTRY
 
     The Company's operating results are dependent on current and anticipated
demand for high-end, high-capacity hard disk drives, which in turn depend on the
demand for high-end PCs, network servers and workstations. The disk drive
industry is cyclical and historically has experienced periods of oversupply and
reduced production levels, resulting in significantly reduced demand for thin
film disks, as well as pricing pressures. The effect of these cycles on
suppliers, including thin film disk manufacturers, has been magnified by hard
disk drive manufacturers' practice of ordering components, including thin film
disks, in excess of their needs during periods of rapid growth, which increases
the severity of the drop in the demand for components during periods of reduced
growth or contraction. In recent years, the disk drive industry has experienced
significant growth, and the Company has expanded its capacity and expects to do
so further. There can be no assurance that such growth will continue, that the
level of demand will not decline, or that future demand will be sufficient to
support existing and future capacity. A decline in demand for hard disk drives
would have a material adverse effect on the Company's business, operating
results and financial condition. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations" and "Business -- Backlog."
 
                                        9
<PAGE>   12
 
Additionally, the hard disk drive industry is intensely competitive, and, in the
past, some disk drive manufacturers have experienced substantial financial
difficulties. To date, the Company has not incurred significant bad debt
expense. However, there can be no assurance that the Company will not face
greater difficulty in collecting receivables or be required to offer more
liberal payment terms in the future, particularly in a period of reduced demand.
Any failure to collect or delay in collecting receivables could have a material
adverse effect on the Company's business, operating results and financial
condition. See "Business -- Customers, Sales and Support."
 
RAPID TECHNOLOGICAL CHANGE
 
     The thin film disk industry has been characterized by rapid technological
development and short product life cycles. Product life cycles typically range
from nine to twelve months. As a result, the Company must continually
anticipate, and adapt its products to meet, demand for increased storage
capacity. Although the Company is continually developing new products and
production techniques, there can be no assurance that the Company will be able
to anticipate technological advances in disk drives and develop products
incorporating such advances in a timely manner or to compete effectively against
its competitors' new products. In addition, there can be no assurance that
customers will certify the Company's products for inclusion in new disk drive
products. The Company anticipates continued changes in the requirements of the
disk drive industry and thin film disk manufacturing technologies, and there can
be no assurance that the future technological innovations will not reduce demand
for thin film disks. The Company's business, operating results and financial
condition will be materially adversely affected if the Company's efforts are not
successful, if the technologies that the Company has chosen not to develop prove
to be competitive alternatives or if any trend develops toward technology that
would replace thin film disks as a storage medium. See "Business -- Industry
Background -- Challenges Facing the Disk Drive Industry" and "-- Products."
 
DEPENDENCE ON SUPPLIERS
 
     The Company relies on a limited number of suppliers for many materials used
in its manufacturing processes, including substrates, texturizers, plating
chemicals, abrasive tapes and slurries, certifier heads, sputter targets and
certain other materials. In general, the Company seeks to have two or three
suppliers for its requirements; however, there can be no assurance that the
Company can secure more than one source for all of its materials requirements in
the future or that its suppliers will be able to meet the Company's requirements
on a timely basis or on acceptable terms. Shortages have occurred in the past
and there can be no assurance that shortages will not occur in the future, or
that materials will be available without longer lead times. Moreover, changing
suppliers for certain materials, such as lube or buffing tape, would require
that the product be requalified with each customer. Requalification could
prevent an early design-in, or could prevent or delay continued participation in
disk drive programs for which the Company's products have been qualified. In
addition, long lead times are required to obtain many materials. Regardless of
whether these materials are available from established or new sources of supply,
these lead times could impede the Company's ability to quickly respond to
changes in demand and product requirements. Furthermore, a significant increase
in the price of one or more of these materials could adversely affect the
Company's business, operating results and financial condition. In addition,
there are only a limited number of providers for thin film disk manufacturing
equipment, such as sputtering machines, glide testers and certifiers, and
ordering additional equipment for replacement or expansion requires long lead
times, limiting the rate and flexibility of capacity expansion. Any limitations
on, or delays in, the supply of materials or equipment could disrupt the
Company's production volume and could have a material adverse effect on the
Company's business, operating results and financial condition. See
"Business -- Sources of Supply."
 
     While the Company has implemented procedures to monitor the quality of the
materials received from its suppliers, there can be no assurance that materials
will meet the Company's specifications and will not adversely impact
manufacturing yields or cause other production problems. Minor variations from
the Company's specifications could have a disproportionately adverse impact on
manufacturing yields. For example, in the quarter ended March 31, 1995, the
Company's operating results were materially adversely affected by chlorine
contamination of its thin film disk products that it believes
 
                                       10
<PAGE>   13
 
resulted from chlorine contamination of disk carriers provided by one of its
suppliers. See "Business -- Manufacturing and Quality -- Quality Assurance."
 
NEED FOR ADDITIONAL FINANCING
 
     The disk media business is capital intensive, and the Company believes that
in order to remain competitive, it will need significant additional financing
resources over the next several years for capital expenditures, working capital,
and research and development. Among other things, the Company's customers prefer
suppliers that can meet a substantial portion of their volume requirements, so
the Company will need to expand its manufacturing capacity to remain
competitive. The Company currently expects to spend in excess of $250 million on
capital expenditures directed toward expansion of production capacity over the
next eighteen months, of which in excess of $150 million are expected to be
incurred within the next 12 months. The Company believes that it will be able to
fund planned expenditures for at least the next twelve months from a combination
of the proceeds of the Offerings, funds available under its credit facilities,
cash flow from operations and existing cash balances. Assuming completion of the
Offerings and the application of the net proceeds therefrom, as of March 31,
1996, the Company would have had approximately $196.1 million in working
capital, including approximately $186.0 million in cash and cash equivalents. In
addition, the Company's operations generated cash flow of $50.4 million during
the year ended March 31, 1996. In order to accelerate or increase the scope of
its facilities expansion, the Company will require additional capital. The
Company intends to use approximately $106 million of the net proceeds of the
Offerings to prepay all of the subordinated promissory notes and redeem the
Company's Series A Preferred Stock, which amounts will not be available for
future operations. Upon completion of the Offerings, the Company will continue
to have significant future obligations and expects that it will require
additional capital to support future growth, if any. The Company may not be able
to obtain additional financing as needed on acceptable terms or at all. If the
Company is unable to obtain sufficient capital, it could be required to curtail
its capital expenditures and research and development expenditures, which could
materially adversely affect the Company's future operations and competitive
position. Moreover, the Company's need to raise additional capital through the
issuance of securities may result in additional dilution to earnings per share.
See "Use of Proceeds," "Capitalization," "Management's Discussion and Analysis
of Financial Condition and Results of Operations -- Liquidity and Capital
Resources" and "Certain Relationships and Related Transactions."
 
MANAGEMENT OF GROWTH
 
     The Company has recently experienced a period of rapid expansion in its
operations that has placed, and could continue to place, a significant strain on
the Company's management and other resources. In addition, through November
1995, some managerial functions were performed by Hitachi Metals, Ltd., and the
Company has only recently added additional resources necessary to enable it to
operate as an independent company. Although the Company's management team has
extensive industry experience, most of its members have only a limited history
with the Company, having joined the Company since February 1994, when Ronald L.
Schauer became Chief Executive Officer. Larry J. Anderson joined the Company as
Vice President, Marketing and Sales in January 1996, and Peter S. Norris joined
the Company as Chief Financial Officer upon completion of the Leveraged
Recapitalization in November 1995. Mr. Norris has subsequently hired additional
members of the finance and accounting organization and has begun to enhance the
reporting, financial controls and management information systems of the Company.
The Company's status as a public company since its March 1996 initial public
offering has placed additional demands on the Company's management, including
its finance and accounting organization. The Company's ability to manage its
expanding operations effectively will require it to continue to improve its
operational, financial, and management information systems, and to train,
motivate and manage its employees. If the Company's management is unable to
manage its operations effectively, the Company's business, operating results and
financial condition could be adversely affected. See "Management."
 
     Because the Company has been operating at close to full capacity, growth in
the Company's net sales depends on the successful expansion by the Company of
its manufacturing capacity. Although the
 
                                       11
<PAGE>   14
 
Company has increased its production capacity in its existing facility,
significant additional increases will depend on successfully developing a new
production facility at its Fremont, California site and on successfully
expanding aluminum substrate production, and establishing a nickel plating and
polishing capability, at its recently acquired facility in Eugene, Oregon.
Maintaining current production while concurrently pursuing expansion plans at
two sites will place additional strain on the Company's management resources.
There can be no assurance that the Company will be able to successfully increase
capacity and the failure to do so could have a material adverse effect on the
Company's business, operating results and financial condition.
 
INTELLECTUAL PROPERTY AND PROPRIETARY RIGHTS
 
     Although the Company attempts to protect its intellectual property rights
through patents, copyrights, trade secrets and other measures, there can be no
assurance that the Company will be able to protect its technology adequately or
that competitors will not be able to develop similar technology independently.
Patents may not be issued with respect to the Company's pending patent
applications, and its issued patents may not be sufficiently broad to protect
the Company's technology. No assurance can be given that any patent issued to
the Company will not be challenged, invalidated or circumvented or that the
rights granted thereunder will provide adequate protection to the Company's
products. In addition, the Company has only limited patent rights outside the
United States, and the laws of certain foreign countries may not protect the
Company's intellectual property rights to the same extent as do the laws of the
United States.
 
     The Company may from time to time be notified by third parties that it may
be infringing patents owned by such third parties. If necessary, the Company may
have to seek a license under such patent or modify its products and processes in
order to avoid infringement of such patents. There can be no assurance that such
a license would be available on acceptable terms, if at all, or that the Company
could so avoid infringement of such patents, in which case the Company's
business, operating results and financial condition could be materially
adversely affected.
 
     The Company and one of its customers have been contacted by Virgil L.
Hedgcoth concerning the use of certain disk preparation techniques allegedly
patented by Mr. Hedgcoth (the "Hedgcoth Patents"). The Company generally
provides its customers with indemnification for damages sustained by a customer
as a consequence of patent infringement claims arising out of use of the
Company's products and agrees to defend its customers against such claims. Based
on its review of the Hedgcoth Patents, the Company believes that it does not use
the techniques described in the Hedgcoth Patents. The Company is aware that
another manufacturer is currently litigating the validity of the Hedgcoth
Patents. Should they be upheld, there can be no assurance that Mr. Hedgcoth will
not make a claim against the Company, in which case the Company could be
required to defend its position.
 
     Litigation may be necessary to enforce the Company's patents, copyrights or
other intellectual property rights, to protect the Company's trade secrets, to
determine the validity and scope of the proprietary rights of others, or to
defend against claims of infringement or claims for indemnification resulting
from infringement claims by third parties. Such litigation, even if successful,
could result in substantial costs and diversion of resources and could have a
material adverse effect on the Company's business, operating results and
financial condition. See "Business -- Intellectual Property and Proprietary
Rights."
 
DEPENDENCE ON KEY PERSONNEL
 
     The Company's future operating results depend in significant part upon the
continued contributions of its officers and personnel, many of whom would be
difficult to replace. The Company does not have employment agreements with any
employee. The loss of its officers or other key personnel, who are critical to
the Company's success, could have a material adverse effect on the business,
operating results and financial condition of the Company. See "Management." In
addition, the Company's future operating results depend in part upon its ability
to attract, train, retain and motivate other qualified management, technical,
manufacturing, sales and support personnel for its operations. Competition for
such personnel is intense, especially since many of the Company's competitors
are located near the
 
                                       12
<PAGE>   15
 
Company's facilities in Fremont, California. Among the competitive factors in
attracting personnel are compensation and benefits, equity incentives and
geographic location. There can be no assurance that the Company will be
successful in attracting or retaining such personnel. The loss of the services
of existing personnel as well as the failure to recruit additional personnel
could materially adversely effect the Company's business, operating results and
financial condition. See "Business -- Employees."
 
DEPENDENCE ON FREMONT MANUFACTURING FACILITY; ENVIRONMENTAL ISSUES
 
     The Company's Fremont facility, which currently accounts for all of its
production of finished products, is located near major earthquake faults.
Disruption of operations at the Company's production facility for any reason,
including power failures, work stoppages or natural disasters such as fire,
floods or earthquakes, would cause delays in, or an interruption of, production
and shipment of products, which would materially adversely affect the Company's
business, operating results and financial condition. See
"Business -- Properties."
 
     The Company's operations and manufacturing processes are subject to certain
environmental laws and regulations, which govern the Company's use, handling,
storage, transportation, disposal, emission and discharge of hazardous materials
and wastes, the pre-treatment and discharge of process waste waters and its
emission of air pollutants. The Company has from time to time been notified of
minor violations of environmental laws and regulations, including its waste
water discharge permits, San Francisco Bay Area air quality regulations and
hazardous material regulations including releases of hazardous materials. There
can be no assurance that the Company's failure to comply with either present or
future laws or regulations, which may become more stringent, would not subject
the Company to significant compliance expenses, production suspension or delay,
restrictions on expansion or the acquisition of costly equipment. See
"Business -- Environmental Regulation."
 
RISKS OF INTERNATIONAL SALES
 
     In fiscal 1995 and 1996, substantially all of the Company's net sales
consisted of products delivered to customers in Asia, primarily foreign
subsidiaries of U.S. companies, and the Company anticipates that the substantial
majority of its products will be delivered to customers outside of the United
States for the foreseeable future. Accordingly, the Company's operating results
are subject to the risks of doing business in foreign jurisdictions, including
compliance with, or changes in, the law and regulatory requirements of foreign
jurisdictions, local content rules, taxes, tariffs or other barriers, and
transportation delays and other interruptions. Although presently all of the
Company's sales are made in U.S. dollars, there can be no assurance that future
international sales will not be denominated in foreign currency.
 
CONTROL BY EXISTING STOCKHOLDERS AND ANTI-TAKEOVER EFFECTS
 
     Upon the completion of the Offerings and based on shares outstanding at
March 31, 1996, directors, officers and holders of 5% or more of the outstanding
shares of Common Stock of the Company will own approximately 62% of the
outstanding shares of Common Stock (56% assuming exercise of all outstanding
options and warrants to purchase Common Stock). As a result, the directors,
officers and holders of 5% or more of the outstanding shares of the Company's
Common Stock, acting together, will have the ability to elect all of the
Company's directors and control most corporate actions. Certain provisions of
the Company's Amended and Restated Certificate of Incorporation, Bylaws and
Delaware law, including the provisions of Section 203 of the Delaware General
Corporation Law, which restrict the ability of a substantial stockholder to
acquire the Company, may also discourage certain transactions involving a change
in control of the Company. In addition to the foregoing, the ability of the
Board of Directors to issue "blank check" preferred stock without further
stockholder approval could have the effect of delaying, deferring or preventing
a change in control of the Company. See "Principal and Selling Stockholders" and
"Description of Capital Stock."
 
SUBORDINATION AND ABSENCE OF FINANCIAL COVENANTS
 
     The Notes will be unsecured and subordinated in right of payment in full to
all existing and future Senior Indebtedness of the Company. As a result of such
subordination, in the event of any insolvency,
 
                                       13
<PAGE>   16
 
liquidation or reorganization of the Company, or default on Senior Indebtedness,
the assets of the Company will be available to satisfy obligations on the Notes
only after all Senior Indebtedness has been paid in full, and there may not be
sufficient assets remaining to pay amounts due on any or all of the Notes then
outstanding. The Indenture does not prohibit or limit the incurrence of Senior
Indebtedness or the incurrence of other indebtedness and other liabilities by
the Company, and the incurrence of additional indebtedness and other liabilities
by the Company could adversely affect the Company's ability to satisfy its
obligations on the Notes. As of March 31, 1996, the Company had approximately
$8.5 million of outstanding indebtedness which would have constituted Senior
Indebtedness. The Company anticipates that from time to time it will incur
additional indebtedness, including Senior Indebtedness. Moreover, the cash flow
and consequent ability of the Company to service debt, including the Notes, may
become dependent in part upon the earnings from the business conducted by the
Company through subsidiaries and the distribution of those earnings, or upon
loans or other payments of funds by those subsidiaries, to the Company. See
"Description of Notes -- Subordination."
 
     The Indenture does not contain any financial performance covenants.
Consequently, the Company is not required under the Indenture to meet any
financial tests such as those that measure the Company's working capital,
interest coverage, fixed charge coverage or net worth in order to maintain
compliance with the terms of the Indenture.
 
LIMITATIONS ON REPURCHASE UPON A DESIGNATED EVENT
 
     No Notes may be repurchased at the option of holders upon a Designated
Event if there has occurred and is continuing an Event of Default (other than a
default in the payment of the repurchase price with respect to such Notes on the
repurchase date). If a Designated Event were to occur, there can be no assurance
that the Company would have sufficient financial resources, or would be able to
arrange financing, to pay the repurchase price for all Notes tendered by holders
thereof. The Company's credit agreement with respect to its senior bank
revolving credit facility prohibits the Company from repurchasing any Notes,
which would constitute an event of default under such credit agreement. Any
future credit agreements or other agreements relating to other indebtedness
(including other Senior Indebtedness) to which the Company becomes a party may
contain similar restrictions and provisions. If the Company does not obtain such
a consent or repay the Notes upon a Designated Event, the Company would remain
prohibited from repurchasing the Notes. Any failure by the Company to repurchase
the Notes when required following a Designated Event would result in an Event of
Default under the Indenture whether or not such repurchase is permitted by the
subordination provisions of the Indenture. Any such default may, in turn, cause
a default under Senior Indebtedness of the Company. Moreover, the occurrence of
a Designated Event may cause an event of default under Senior Indebtedness of
the Company. As a result, in each case, any repurchase of the Notes would,
absent a waiver, be prohibited under the subordination provisions of the
Indenture until the Senior Indebtedness is paid in full. See "Description of
Notes -- Repurchase at Option of Holders Upon a Designated Event."
 
VOLATILITY
 
     The trading price of the Company's Common Stock could be subject to wide
fluctuations in response to a variety of factors, including quarterly variations
in operating results, announcements of technological innovations or new products
by the Company, its customers or its competitors, developments in patents or
other intellectual property rights, general conditions in the computer or disk
drive industry, and general economic and market conditions. Additionally, the
stock market in general, and the market for technology stocks in particular, has
experienced extreme price volatility in recent years. This volatility has often
had a substantial effect on the market prices of many technology companies for
reasons unrelated or disproportionate to the operating performance of such
companies. Broad market fluctuations could have a significant impact on the
market price of the Common Stock. See "Underwriting."

SHARES ELIGIBLE FOR FUTURE SALE; REGISTRATION RIGHTS
 
   
     Sales of substantial amounts of the Company's Common Stock in the public
market after the Offerings could adversely affect the market price of the
Company's Common Stock and the Company's ability to raise additional capital at
a price favorable to the Company. Upon completion of the Offerings and based on
shares outstanding at March 31, 1996, there will be 43,979,178 shares of Common
Stock outstanding, of which 13,660,000 shares (assuming the issuance of the
4,000,000 shares offered hereby) will be eligible for immediate sale. 30,319,178
of the shares are subject to lockup agreements with the underwriters of the
Company's initial public offering. Such lockup agreements expire four days after
the announcement by the Company of its operating results for the three months
ending September 30, 1996 as to 8,153,000 restricted shares. Of these 8,153,000
restricted shares, 3,922,314 will be available for immediate sale pursuant to
Rule 144 and Rule 701, 146,382 may be available for immediate sale pursuant to
Rule 144 and Rule 701 based upon achievement of certain performance goals, and
the remaining 4,084,304 will be subject to rights of repurchase in favor of the
Company that expire at various dates through December 2004 pursuant to monthly
vesting, or earlier upon the achievement of certain performance goals, and may
not be resold until such rights expire. Such lockup agreements expire on March
13, 1997 as to the remaining 21,968,057 restricted shares. The holders of such
21,968,057 shares will be eligible to sell such shares pursuant to Rule 144 upon
the expiration of a two-year holding period from the date such shares were
acquired (in most cases November 30, 1995), subject to certain volume
limitations under Rule 144. The holders of 30,541,851 shares of Common Stock and
warrants to purchase shares of Common Stock are entitled to certain rights with
respect to registration of such shares of Common Stock for offer or sale to the
public beginning 180 days after the date of this Prospectus. In addition, the
Company has filed a registration statement covering an aggregate of 7,312,029
shares of Common Stock reserved for issuance under the Company's 1995 Stock
Option Plan, 1996 Equity Incentive Plan, 1996 Non-Employee Directors' Stock
Option Plan and Employee Stock Purchase Plan. As of May 31, 1996 options to
purchase approximately 459,883 of these shares were exercisable and immediately
saleable. The remainder of these shares will become exercisable and saleable at
various dates through April 2000 pursuant to monthly vesting. See
"Management -- Employee Benefit Plans," "Description of Capital
Stock -- Registration Rights," "Shares Eligible for Future Sale" and
"Underwriting."
    
 
ABSENCE OF PUBLIC MARKET FOR THE NOTES
 
     Prior to the Note Offering, there has been no trading market for the Notes.
The Company expects that the Notes will trade on the over-the-counter market.
However, there can be no assurance that an active trading market for the Notes
will develop or, if such market develops, as to the liquidity or sustainability
of such market. The Underwriters named on the cover page of this Prospectus have
advised the Company that they currently intend to make a market in the Notes,
but they are not obligated to do so and may discontinue such market making at
any time. There can be no assurance that an active market for the Notes will
develop and continue upon completion of the Note Offering or that the market
price of the Notes will not decline. Various factors such as changes in
prevailing interest rates or changes in perceptions of the Company's
creditworthiness could cause the market price of the Notes to fluctuate
significantly. The trading price of the Notes could also be significantly
affected by the market price of the Common Stock, which could be subject to wide
fluctuations in response to a variety of factors, including quarterly variations
in operating results, announcements of technological innovations or new products
by the Company, its customers or its competitors, developments in patents or
other intellectual property rights, general conditions in the computer or disk
drive industry and general economic and market conditions. Factors creating
volatility in the trading price of the Common Stock could have a significant
impact on the trading price of the Notes.

                                  THE COMPANY
 
     HMT Technology Corporation is an independent supplier of high-performance
thin film disks for high-end, high-capacity hard disk drives, which in turn are
used in high-end PCs, network servers and workstations. HMT was incorporated in
Delaware in 1988 as a subsidiary of Hitachi Metals, Ltd. ("Hitachi Metals") to
acquire certain assets and certain liabilities of the thin film division of
Xidex Corporation, which had been producing thin film disks since 1983. Since
completing the acquisition, the Company has continued to supply thin film disks
to manufacturers of hard disk drives. As used in this Prospectus, the terms
"Company" and "HMT" refer to HMT Technology Corporation, a Delaware corporation.
The Company's principal offices are located at 1055 Page Avenue, Fremont,
California 94538, and its telephone number is (510) 490-3100.
 
                           LEVERAGED RECAPITALIZATION
 
RECAPITALIZATION TRANSACTION
 
     On November 30, 1995 the Company effected a leveraged recapitalization (the
"Leveraged Recapitalization"). The Leveraged Recapitalization and related
transactions consisted of: (i) the repurchase by the Company from Hitachi Metals
of shares of Common Stock representing all the outstanding capital stock of the
Company for an aggregate purchase price of $52.1 million in cash; (ii) the
recapitalization of the Company through the issuance of 21,968,057 shares of
Common Stock for an aggregate purchase price of approximately $0.7 million,
5,900,000 shares of Series A Preferred Stock for an aggregate purchase price of
approximately $59.0 million, $47.0 million of subordinated promissory notes
("Subordinated Notes") and $60.0 million in senior debt with associated warrants
to purchase 701,344 shares of Common Stock at an exercise price of $0.0003 per
share. See "Description of Capital Stock -- Warrants." The purchasers of the
Company's securities in the Leveraged Recapitalization included certain
investment funds affiliated with Summit Partners, L.P. ("Summit Partners") and
certain other investment funds, the Company's management and employees and
Hitachi Metals. The terms of the Leveraged Recapitalization were determined
through negotiations between Hitachi Metals and Summit Partners, who, prior to
the Leveraged Recapitalization, did not have any affiliation with the Company.
Pursuant to these negotiations, the shares of Common Stock were valued at $0.03
per share. The Series A Preferred Stock was valued at $10.00 per share, and the
Subordinated Notes were valued at face value. The values of these securities
were confirmed by a third party appraisal. See "-- Third Party Appraisal."
 
     The Leveraged Recapitalization has been accounted for as a
recapitalization, and accordingly, no change in the accounting basis of the
Company's assets has been made.
 
     As of November 30, 1995 (immediately prior to the Leveraged
Recapitalization), the Company had $98.5 million in assets and $122.7 million in
liabilities. Immediately following the Leveraged Recapitalization, the Company
had $110.9 million in assets, $132.1 million in liabilities (including a $60.0
million senior bank term loan and $47.0 million of Subordinated Notes) and $59.0
million of Series A Preferred Stock. See "Certain Relationships and Related
Transactions -- Leveraged Recapitalization."
 
THIRD PARTY APPRAISAL
 
     The Company retained Willamette Management Associates ("Willamette") to
provide an opinion as to the fair market value of certain securities, including
Common Stock issued as of November 30, 1995 and January 9, 1996, to assist the
Company's Board of Directors in confirming the fair market value of the
Company's Common Stock for incentive stock options granted by the Company.
Willamette interviewed the Company's management, and was informed of the history
of the Company, of the various risk factors facing the Company, and of the
Company's expectation at the time of an initial public offering of the Common
Stock. Willamette's appraisal of the intrinsic value of the Common Stock on
those dates did not include the proceeds of any subsequent public offering.
 
                                       16
<PAGE>   19
 
Willamette's valuation methods included a prior transaction approach, a market
approach based on comparable publicly traded companies, and an income approach
based on discounted cash flows. Willamette's valuation analysis included an
assessment of all of the capital components issued in connection with the
Leveraged Recapitalization, including Common Stock, Series A Preferred Stock,
and the Subordinated Notes as well as consideration of the November 1995
redemption of the equity ownership of Hitachi Metals, which was an important
indication of the fair value of the Company's Common Stock. That transaction
occurred between a sophisticated financial buyer and seller and was similar to
prices under negotiation with other potential buyers of the business.
 
     Willamette concluded that the fair market value of the Common Stock at
November 30, 1995 was $0.03 per share and at January 9, 1996 was $0.09 per
share. With regard to the Series A Preferred Stock and the Subordinated Notes,
Willamette concluded that the stated values of the Series A Preferred Stock of
$10.00 per share and of the Subordinated Notes of face value were reasonable
estimations of their fair market values. Management is responsible for estimates
of the value of the Company's Common Stock for purposes of measuring in its
financial statements compensation attributable to stock options granted to
employees. In its valuation of the Company's Common Stock at January 9, 1996,
management considered, in addition to the appraiser's report, the Company's
forecasted earnings before depreciation, interest and taxes, and the likelihood
that the Company could successfully restructure its capitalization and provide
liquidity to holders of the Common Stock within the near term.
 
SUBSEQUENT FINANCING
 
     In March 1996, the Company completed its initial public offering of
8,400,000 shares of Common Stock at $10.00 per share. An additional 1,260,000
shares were sold in April 1996 upon exercise of the over-allotment option by the
underwriters of that offering. Of the net proceeds to the Company of
approximately $88.7 million, approximately $50.2 million was used to repay the
principal balance and interest then outstanding under the senior bank term loan
incurred in connection with the Leveraged Recapitalization.
 
     Upon the completion of the Offerings described in this Prospectus, the
Company intends to prepay the principal balance of the currently outstanding
Subordinated Notes ($47.0 million) and to redeem the currently outstanding
Series A Preferred Stock ($59.0 million), thereby retiring the last of the
Company's debt obligations that were incurred in connection with the Leveraged
Recapitalization. See "Use of Proceeds."

<PAGE>   20
 
                                USE OF PROCEEDS
 
     The net proceeds to the Company from the sale of the Common Stock offered
by the Company are estimated to be approximately $98.8 million based on an
assumed public offering price of $26.00 per share and after deducting
underwriting discounts and commissions and estimated offering expenses. The net
proceeds to the Company from the sale of the Notes offered hereby are estimated
to be approximately $145.6 million after deducting underwriting discounts and
commissions and estimated offering expenses ($167.5 million if the Underwriters'
over-allotment option is exercised in full). Neither the closing of the Common
Stock Offering nor the closing of the Note Offering is conditioned on the
closing of the other offering. The Company will not receive any proceeds from
the sale of Common Stock by the Selling Stockholders pursuant to the
over-allotment options granted to the Underwriters in the Common Stock Offering.
 
     The Company expects to use approximately $47.0 million of the net proceeds
of the Offerings to prepay the Subordinated Notes, together with all accrued but
unpaid interest, approximately $59.0 million of the net proceeds of the
Offerings to redeem the Series A Preferred Stock, and the remainder of the net
proceeds for capital expenditures, including investment in facilities and
equipment, working capital and other general corporate purposes. The currently
outstanding Subordinated Notes, which were incurred in connection with the
Leveraged Recapitalization, mature on December 31, 2005 and currently bear
interest at 12.0% per year. See "Certain Relationships and Related
Transactions -- Leveraged Recapitalization." The Company currently expects to
spend in excess of $250 million and $150 million on capital expenditures over
the next 18 months and 12 months, respectively. A portion of the net proceeds
may also be used to acquire businesses for the purpose of capacity expansion.
The Company has no present plans, agreements or commitments and is not currently
engaged in any negotiations with respect to acquisition of any business that
would be material to the Company. Pending such uses, the Company intends to
invest the net proceeds in short-term, interest bearing, investment grade
financial instruments. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations -- Liquidity and Capital Resources."
 
                                DIVIDEND POLICY
 
     The Company has never declared or paid cash dividends on its Common Stock.
The Company currently intends to retain all future earnings for use in its
business, and does not anticipate paying cash dividends on the Common Stock in
the foreseeable future. In addition, no dividends may be paid on Common Stock as
long as the Series A Preferred Stock remains outstanding, and the terms of the
Company's revolving credit facility prohibit the payment of dividends without
the banks' prior approval. See Notes 5 and 8 of Notes to Consolidated Financial
Statements.

     related to debt extinguishment. Earnings were inadequate to cover fixed
     charges for all periods prior to fiscal 1996. The deficiencies of earnings
     were approximately $22.0 million, $17.6 million, $17.4 million and $8.9
     million for fiscal 1992, 1993, 1994 and 1995.

                      MANAGEMENT'S DISCUSSION AND ANALYSIS
                OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
     This Management's Discussion and Analysis of Financial Condition and
Results of Operations and other parts of this Prospectus contain forward-looking
statements that involve risks and uncertainties. The Company's actual results
may differ significantly from the results discussed in the forward-looking
statements. Factors that might cause such a difference include, but are not
limited to, those discussed in "Risk Factors."
 
OVERVIEW
 
     The following discussion of the Company's financial condition and results
of operations should be read in conjunction with the Company's consolidated
financial statements and notes thereto included elsewhere in this Prospectus.
HMT Technology Corporation is an independent supplier of high-performance thin
film disks for high-end, high-capacity hard disk drives, which in turn are used
in high-end PCs, network servers and workstations. HMT was incorporated in 1988
as a subsidiary of Hitachi Metals for the purpose of acquiring certain assets
and certain liabilities of the thin film division of Xidex Corporation, which
had been producing thin film disks since 1983. Since completing the acquisition,
the Company has continued to supply thin film disks to manufacturers of hard
disk drives. On November 30, 1995, the Company effected the Leveraged
Recapitalization pursuant to which the Company repurchased from Hitachi Metals
all of the outstanding shares of Common Stock of the Company, and certain
investment funds, members of management and Hitachi Metals purchased Common
Stock, Series A Preferred Stock and Subordinated Notes. During March and April
1996, the Company sold 9,660,000 shares of Common Stock at $10.00 per share
(including exercise of the underwriters' over-allotment option) through its
initial public offering. The net proceeds (after underwriter's discounts and
commissions and other costs associated with the initial public offering) totaled
$88.7 million.
 
     Beginning in 1994, HMT's new management team refocused the strategy and
operations of the Company. The new management concentrated on the 3 1/2-inch
disk form factor, focused on the high-end, high-capacity segment of the disk
drive market and expanded the Company's customer base. In addition, HMT
implemented an extensive quality assurance program, developed proprietary
manufacturing processes and optimized production capacity utilization. These
changes resulted in higher production volumes, lower unit costs, and higher
average selling prices primarily associated with new high-end products. As a
result, the Company has increased sales and improved gross margins, achieving
net income of $46.4 million for the year ended March 31, 1996 compared with a
net loss of $8.9 million for fiscal 1995. The rate of improvement in the
Company's operating results experienced in fiscal 1996 is not expected to
continue in future periods.
 
     The Company derives substantially all of its sales from the sale of thin
film disks to a small number of customers. Loss of or a reduction in orders from
one or more of the Company's customers could result in a substantial reduction
in net sales. Because many of the Company's expense levels are based, in part,
on its expectations as to future revenues, decreases in net sales may result in
a disproportionately greater negative impact on operating results. Due to the
rapid technological change and frequent development of new disk drive products,
it is common in the industry for the relative mix of customers and products to
change rapidly, even from quarter to quarter. At any one time the Company
typically supplies disks in volume for fewer than ten disk drive products.
 
     The Company has recently experienced a period of rapid expansion in its
operations that has placed, and could continue to place, a significant strain on
the Company's management and other resources. In addition, through November
1995, some managerial functions were performed by Hitachi Metals, and the
Company has only recently added additional resources necessary for it to operate
as an independent company. Although the Company's management team has extensive
industry experience, most of its members have only a limited history with the
Company, having joined the Company since February 1994. The Company has recently
announced plans to construct a new production facility at
 
                                       21
<PAGE>   24
 
its Fremont, California site. In addition, the Company recently acquired an
aluminum substrate manufacturing facility and related equipment located in
Eugene, Oregon. See "Business -- Manufacturing and Quality -- Manufacturing
Facilities and Capability."
 
     In connection with the Leveraged Recapitalization, the Company issued
5,900,000 shares of Series A Preferred Stock. Beginning on January 1, 1998, the
shares of Series A Preferred Stock will begin to accrue cumulative dividends at
a rate of approximately $5.9 million a year. However, the Company is required to
accrete for accounting purposes the aggregate amount of dividends payable under
the terms of the Series A Preferred Stock through the mandatory redemption date.
Such accretion reduced earnings available for holders of Common Stock by $1.2
million for fiscal 1996. See Note 7 of Notes to Consolidated Financial
Statements. If the Series A Preferred Stock is redeemed prior to January 1,
1998, none of such accreted amounts will be payable by the Company. The Company
expects to use a portion of the net proceeds of the Offerings to redeem the
Series A Preferred Stock. Other assets at March 31, 1996 include approximately
$0.9 million of remaining unamortized deferred financing costs associated with
the Company's revolving credit facility.
 
     Due to the changes in ownership resulting from the Leveraged
Recapitalization, utilization of net operating losses is limited to
approximately $0.8 million per year over the loss carryforward period (expiring
between 2008 and 2010). The benefit from the net operating losses was recorded
in the quarter ended December 31, 1995. Had the Company been obligated to pay
taxes at the statutory rates for fiscal 1996, net income would have been $30.7
million.

</TABLE>
 
FISCAL YEARS ENDED MARCH 31, 1994, 1995 AND 1996
 
     Net Sales.  Net sales were $64.2 million in fiscal 1994, $72.9 million in
fiscal 1995 and $194.4 million in fiscal 1996. This represented an increase of
13.5% from fiscal 1994 to fiscal 1995, and 166.7% from fiscal 1995 to fiscal
1996. The increase in net sales in fiscal 1995 was a result of increased
production volumes due to improved manufacturing processes and higher unit
shipments, partially offset by a manufacturing disruption experienced in the
three months ended March 31, 1995. The increase in net sales in fiscal 1996 was
primarily attributable to an increase in manufacturing capacity and improved
utilization of existing capacity, improved manufacturing processes, and
increased yields, resulting in
 
                                       22
<PAGE>   25
 
higher production volume and unit shipments, as well as higher average selling
prices primarily associated with the sale of new high-end products.
Substantially all of the Company's net sales consist of products delivered to
customers in Asia, primarily foreign subsidiaries of U.S. companies.
 
     Gross Profit (Loss).  Gross margin was (5.3%) in fiscal 1994, 7.3% in
fiscal 1995 and 38.4% in fiscal 1996. The increases in gross margin in fiscal
1995 and fiscal 1996 were a result of decreased unit production costs, improved
utilization of manufacturing capacity, improved manufacturing processes,
increased yields and the absorption of fixed costs over higher unit production
volume effected by the refocusing of the strategy and operations of the Company.
The increase in gross margin in fiscal 1995 also reflected a partial offset by
the manufacturing disruption experienced during the three months ended March 31,
1995.
 
     Research and Development.  Research and development expenses were $2.8
million or 4.3% of net sales in fiscal 1994, $3.1 million or 4.3% of net sales
in fiscal 1995 and $3.8 million or 2.0% of net sales in fiscal 1996. Research
and development expenses increased in absolute dollars in fiscal 1995 and 1996
due to an increase in headcount related to the Company's new product
introductions. The decrease of research and development expenses as a percentage
of net sales in fiscal 1996 was primarily a result of the substantial increase
in net sales over the same period. The Company develops manufacturing processes
for new products directly on active production lines during the research and
development phase, avoiding the need for substantial capital investment in
dedicated research equipment. The Company anticipates that research and
development expenses will increase in absolute dollars in future periods,
although as a percentage of net sales, research and development expenses may
fluctuate.
 
     Selling, General and Administrative.  Selling, general and administrative
expenses were $5.1 million or 8.0% of net sales in fiscal 1994, $4.2 million or
5.8% of net sales in fiscal 1995 and $7.8 million or 4.0% of net sales in fiscal
1996. The decrease in fiscal 1995 was primarily a result of reduction in
headcount associated with a management reorganization and the associated
reduction in compensation expense. The fiscal 1996 increase in selling, general
and administrative expenses in absolute dollars reflected increased headcount
necessary to support higher production volume and unit shipments, while the
decline as a percentage of net sales primarily reflects the increase in net
sales over the same period. The Company anticipates that selling, general and
administrative expenses will continue to increase in absolute dollars as
headcount is increased to support anticipated higher levels of production volume
and unit shipments, as well as the demands of administering a stand-alone public
entity, although as a percentage of net sales, selling general and
administrative expenses may fluctuate.
 
     Recapitalization Expenses.  On November 30, 1995, the Company effected the
Leveraged Recapitalization, and recorded a $4.3 million charge for related
expenses for the quarter ending December 31, 1995.
 
     Interest Expense and Other, Net.  Interest expense and other, net was $6.0
million or 9.3% of net sales in fiscal 1994, $6.9 million or 9.4% of net sales
in fiscal 1995 and $8.6 million or 4.4% of net sales in fiscal 1996. The
increase in fiscal 1995 was primarily the result of increased short-term
borrowings. The fiscal 1996 increase in absolute dollars was primarily a result
of higher average debt balances and interest rates, as compared to fiscal 1995.
The Company anticipates interest expense and other, net may fluctuate in
absolute dollars, but will decline as a percentage of net sales as a result of
lower average debt balances and improved capital resources resulting from the
initial public offering in March 1996.
 
     Provision for Income Taxes.  The Company recorded an income tax provision
of $22,000, $20,000 and $2.6 million in fiscal 1994, 1995 and 1996,
respectively. During fiscal 1996, the Company assessed the recoverability of
deferred tax assets and, based on expectations about operating results for the
three months ending March 31, 1996 and the fiscal year ending March 31, 1997,
determined it was more likely than not that the entire balance of deferred tax
assets would be recovered. As the facts that supported the reduction of the
valuation allowance related to the period immediately following the
 
                                       23
<PAGE>   26
 
Leveraged Recapitalization, the Company reduced its income tax expense by
approximately $6.9 million to reflect the tax benefit associated with
recognition of deferred tax assets at December 31, 1995. The recognition of
deferred tax assets and the utilization of $12.7 million of net operating loss
carryforwards produced an effective tax rate of 5.2% for fiscal 1996. Due to
losses in fiscal 1994 and 1995, the Company required no federal income tax
provision. The income tax provision recorded during fiscal 1994 and 1995 was
based upon state income taxes of Hitachi Metals allocated to the Company. The
Company anticipates an effective tax rate of approximately 38% in future
periods.
 
     Extraordinary debt extinguishment costs, net of income taxes.  Pursuant to
the senior bank credit agreement, the Company repaid the balance of a senior
bank term loan incurred in connection with the Leveraged Recapitalization on
March 14, 1996, after completion of the initial public offering. As a result,
the Company recorded a one-time non-cash charge of $1.1 million, net of income
taxes, for the write-off of the portion of unamortized debt issue costs related
to the senior bank term loan.
 
ASSET PURCHASE
 
     During May 1996, the Company purchased an aluminum substrate manufacturing
facility and other related equipment in Eugene, Oregon for approximately $5.0
million. The acquisition will be accounted for as an asset purchase, and
acquisition related expenses are not expected to have a significant impact on
first quarter fiscal 1997 results.

QUARTERLY RESULTS OF OPERATIONS
 
     The following table sets forth certain unaudited quarterly consolidated
financial information for each of the Company's last eight quarters. The Company
believes that all necessary adjustments, including normal recurring accruals,
have been included in the amounts stated below to present fairly the selected
quarterly information when read in conjunction with the Consolidated Financial
Statements and Notes thereto included elsewhere in this Prospectus. The
operating results for any quarter are not necessarily indicative of results for
any future periods or for the entire fiscal year.
 
     The Company operates under thirteen- to fourteen-week quarters that end on
the Sunday closest to calendar quarter end. As a result, a fiscal quarter may
not end on the same day as the calendar quarter end. For convenience of
presentation, the following unaudited quarterly consolidated financial
information has been shown as ending on the last day of the calendar quarter.

     The Company's operating results historically have been, and may continue to
be, subject to significant quarterly and annual fluctuations. As a result, the
Company's operating results in any quarter may not be indicative of its future
performance. Factors affecting operating results include: market acceptance of
new products; timing of significant orders; changes in pricing by the Company or
its competitors; timing of product announcements by the Company, its customers
or its competitors; order cancellations, modifications and quantity adjustments
and shipment reschedulings; changes in product mix; manufacturing yields; the
level of utilization of the Company's production capacity; increases in
production and engineering costs associated with initial manufacture of new
products; and changes in the cost of or limitations on availability of
materials. The impact of these and other factors on the Company's revenues and
operating results in any future period cannot be forecasted with certainty. The
Company's expense levels are based, in part, on its expectations as to future
revenues. Because the Company's sales are generally made pursuant to purchase
orders that are subject to cancellation, modification, quantity reduction or
rescheduling on short notice and without significant penalties, the Company's
backlog as of any particular date may not be indicative of sales for any future
period, and such changes could cause the Company's net sales to fall below
expected levels. If revenue levels are below expectations, operating results are
likely to be materially adversely affected. Net income, if any, and gross
margins may be disproportionately affected by a reduction in net sales because a
proportionately smaller amount of the Company's expenses varies with its
revenues.

     During fiscal 1996, HMT increased its manufacturing capacity by balancing
manufacturing through addition of sputtering lines and other production
equipment, improving utilization of existing manufacturing capacity, and
improving manufacturing processes and yields. As a result, an increase in unit
shipments and, to a lesser extent, higher average selling prices associated with
new high-end products led to increased net sales in each quarter of fiscal 1996.
Gross margin also increased during this period primarily as a result of lower
unit production costs and higher average selling prices associated with new
high-end products.
 
     The Company experienced significantly decreased net sales and negative
gross margins for the three months ended March 31, 1995 primarily as a result of
a manufacturing disruption and the related return of a significant number of
disks. This disruption, which resulted from contaminated material from one of
the Company's suppliers, caused both lost production and sales and resulted in a
significant write-off of inventory that had been contaminated. See
"Business -- Sources of Supply."
 
     The decrease in gross margin for the three months ended December 31, 1994
was primarily the result of a large portion of shipments of an older product
with lower average selling prices.
 
     Research and development expenses have generally increased during the
periods presented, but have fluctuated quarterly depending primarily upon the
timing of additions to Company's engineering staff and the number and nature of
projects under development. In the three months ended March 31, 1995, research
and development expenses increased marginally in absolute dollars, but increased
significantly as a percentage of net sales, primarily a result of lower sales
during the same period.
 
     Selling, general and administrative expenses increased significantly as a
percentage of net sales in the three months ended March 31, 1995 primarily as a
result of lower sales during the same period, and increased in the three months
ended December 31, 1995 primarily as a result of increased legal and
environmental reserves. Selling, general and administrative expenses have
generally increased in absolute dollars over the past seven quarters as
headcount was increased to support expanding production volume and unit
shipments.
 
     During the three months ended December 31, 1995, the Company recorded
recapitalization expenses of $4.3 million in connection with the Leveraged
Recapitalization.
 
     During the three months ended March 31, 1996, the Company repaid the
balance of a senior bank term loan and recorded a one-time non-cash charge of
$1.1 million, net of income taxes, for the write-off of the portion of
unamortized debt issue costs related to the senior bank term loan.
 
     During the three months ended December 31, 1995, the Company reduced its
income tax expense to reflect a $6.8 million tax benefit associated with the
recognition of deferred tax assets and the utilization of $10.2 million of net
operating loss carryforwards, producing a net tax benefit of $6.0 million. The
income tax provision recorded during the three months ended March 31, 1996 was
$7.9 million, reflecting an effective tax rate of approximately 38%. The Company
anticipates an effective tax rate of approximately 38% in future periods.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     In fiscal 1994, the Company financed its cash requirements through cash
from investing activities, primarily the refinancing of $19.6 million in
equipment. In fiscal 1995, the Company financed its cash requirements primarily
through cash from operations. During fiscal 1996, the Company financed its cash
requirements primarily through cash from operating and financing activities.
 
     The Company's operations provided net cash of $8.7 million and $50.4
million for fiscal 1995 and 1996, respectively. Cash generated during fiscal
1996 reflects net income plus depreciation and amortization, as well as an
increase in liabilities, partially offset by increases in receivables and
deferred income taxes. Increased sales and improved margins contributed to the
positive cash flow provided by operations in each of the past two years.
 
                                       27
<PAGE>   30
 
     For fiscal 1995 and 1996, net cash used in investing activities was $7.3
million and $35.5 million, respectively. The Company invested $7.3 million and
$39.6 million in property, plant and equipment during fiscal 1995 and 1996,
respectively.
 
     For fiscal 1995 and 1996, net cash from financing activities was $(0.6)
million and $20.0 million, respectively. Cash provided by financing activities
for fiscal 1996 reflects the $76.9 million in cash generated from the sale of
common stock during the Company's initial public offering (before exercise of
the underwriters' over-allotment option, which was exercised after the
completion of fiscal 1996), partially offset by the repayment of the senior bank
term loan and the net cash used for the Leveraged Recapitalization, which was
effected on November 30, 1995, through a $60.0 million senior bank term loan and
an aggregate of $106.7 million in debt and equity financing provided by certain
investment funds, management and employees, and Hitachi Metals.
 
     As of March 31, 1996, the Company's principal sources of liquidity
consisted of $35.8 million in cash and cash equivalents, and a $30.0 million
revolving credit facility under which there were no borrowings. At March 31,
1996, the Company had indebtedness of $47.0 million in principal amount of
Subordinated Notes payable to existing stockholders that bear interest at 12.0%
(increasing by 1% per year commencing January 1, 1999) and begin to require
annual payments of principal on December 31, 2003. The Company also had $59.0
million of Series A Preferred Stock. The Company expects to use approximately
$47.0 million of the net proceeds of the Offerings to prepay the Subordinated
Notes, together with all accrued but unpaid interest, approximately $59.0
million of the net proceeds of the Offerings to redeem the Series A Preferred
Stock, and the remainder of the net proceeds for capital expenditures, including
investment in facilities and equipment, working capital and other general
corporate purposes. See Note 7 of Notes to the Consolidated Financial
Statements, "Description of Capital Stock" and "Use of Proceeds." The revolving
credit facility is secured by all of the Company's assets. Subsequent to March
31, 1996, the Company received an additional $11.7 million in cash for Common
Stock sold pursuant to the over-allotment option of the underwriters of the
Company's initial public offering. The Company expects to spend in excess of
$250.0 million on capital expenditures directed toward expansion of production
capacity over the next eighteen months.
 
     The Company believes existing cash balances, cash generated from
operations, and funds available under its credit facilities, together with the
proceeds of the Offerings, will provide adequate cash to fund its operations for
at least the next twelve months. While operating activities are expected to
provide cash in certain periods, continued expansion of the Company's
manufacturing capacity will require the Company to obtain additional sources of
financing. Additional sources of long-term liquidity could include cash
generated from operations and debt and equity financings. The Company continues
to have significant future obligations and expects that it will require
additional capital to support planned expansion of the Company's manufacturing
capacity and growth, if any. There can be no assurance that the Company will be
able to obtain alternative sources of financing on favorable terms, if at all,
at such time or times as the Company may require such capital.

     HMT is an independent supplier of high-performance thin film disks for
high-end, high-capacity hard disk drives, which in turn are used in high-end
PCs, network servers and workstations. The disks currently being shipped by the
Company are primarily for disk drives with storage capacities ranging from 1.6
to 9 gigabytes (using three to 12 disks), and all have coercivity levels of 1900
Oe or higher. Since March 1994, the Company has focused on addressing the needs
of this high-end, high-capacity segment of the disk drive market. HMT believes
that its recent operating results reflect its success in meeting these needs and
that its future growth and success depend on its ability to continue to develop
and market products that enable its customers to produce high-performance disk
drives for high-end data storage applications. The Company provides a range of
magnetic density points (coercivities), glide heights and disk thicknesses to
match the design and performance requirements of each particular customer. The
Company currently focuses all of its production capacity on 3 1/2-inch disks,
although it is capable of producing disks in other standard form factors. In
fiscal 1996, HMT sold its disks to Maxtor, Western Digital, Micropolis, Quantum,
Iomega Corporation ("Iomega"), and Hewlett-Packard Company ("Hewlett-Packard").
The Company has also recently begun shipping disks to Samsung Electronics
Company Limited ("Samsung").
 
INDUSTRY BACKGROUND
 
  The Disk Drive Market
 
     Market demand for disks and disk drives is growing rapidly, stimulated by
demand for new computers, upgrades to existing computers and the growing use of
sophisticated network servers. The introduction of increasingly powerful
microprocessors and more memory intensive software, combined with the
development and growth of multimedia computing applications and Internet usage,
have stimulated demand for PCs in both the home and business markets. According
to International Data Corporation ("IDC"), worldwide shipments of PCs were 39
million units in 1993 and 58 million units in 1995, and are projected to reach
approximately 104 million units in 1999. In addition, the PC server market,
driven by the trend toward networking applications and the expansion of the
Internet, is expected to grow substantially through the year 2000.
 
     The combined demand from the PC and server markets has resulted in strong
growth in unit shipments of disk drives. Worldwide shipments of hard disk drives
were 50 million units in 1993 and 89 million units in 1995 and are projected to
reach 144 million units in 1997. According to IDC, the worldwide market for hard
disk drives was $22 billion in 1995. Strong overall demand for disk drives has
also stimulated the growth of the thin film disk market. According to Trend
Focus, the number of thin film disks produced in 1993 was 134 million, in 1995
was 256 million and is projected to reach 416 million in 1997. The worldwide
market for thin film disks is estimated to have been $3.3 billion in 1995.
 
     The applications being developed for PCs require greater storage capacity
and, as a result, have sharply increased the demand for high-capacity disk
drives. Users purchasing newer PCs for business and home are commonly attracted
by the availability of greater processing power, larger databases, multimedia
and other memory intensive applications and more sophisticated operating
systems, such as Windows 95 or Windows NT. Increasing use of the Internet and
on-line data, including image storage and retrieval, have further stimulated the
demand for storage capacity. The disk drive industry has responded to this
demand with significant technology and product advances. As a result, mean
storage capacity per disk drive has increased from 213 megabytes ("MB") in 1993
to 690 megabytes in 1995. Meanwhile, the average number of disks per drive has
remained relatively constant at about 2.5 disks. While storage capacity has
grown, the cost per MB has fallen from $1.26 in 1993 to $0.32 in 1995. Today's
market continues to generate pressure for advances to facilitate these trends in
computing,
 
                                       29

especially at the high-end. Thus, the Company believes that success in the disk
drive market has depended and for the foreseeable future will depend on the
ability of the disk drive manufacturer, together with its suppliers of critical
components, such as thin film disks, to keep pace with these advances.
 
     Recently, removable-media storage devices, including removable hard disk
drives, have received increased attention in the data storage market. Removable
hard disk drives utilize cartridges incorporating thin film disks and combine
the high-capacity and rapid access of hard disk drives with the benefits of
removability. These devices can be used peripherally to increase the storage
capacity for PCs.
 
  Disk Drive Technology
 
     The basic elements of the disk drive, sized to fit various industry form
factors, have remained essentially the same since hard disk drives were first
introduced. The principal components of a hard disk drive are disks, heads,
spindle and actuator mechanics and electronics. Each disk drive typically
contains from one to ten disks that are attached to a spindle/motor assembly
within a sealed enclosure. The electronics control the spinning of the disk, the
positioning of the head and the writing and retrieval of data stored on the
disk. The recording head is a small magnetic transducer that, when the disk is
spinning, "flies" just above the disk surface. Data are written on
circumferential tracks on the disk when the electronic channel sends current
pulses to the head. The head converts these pulses to magnetic fields that cause
the magnetic layer within the disk and under the recording head to become
magnetized, oriented in the direction of the head's magnetic field. Reversing
the current in the head reverses the direction of the magnetic field on the
disk. During the read-back process, as the head scans over the disk, magnetic
flux from the disk's magnetic layer is picked up by the head and induces an
electrical current which is converted into voltage. The output signal voltage is
then transformed into digital data by the read channel electronics. The
following diagram illustrates the principal components of a typical hard disk
drive:
 
     Major improvements in disk drive performance have been based on
technological advances in the principal components. In a typical disk drive
today, the spindle/motor assembly rotates the disk at 4,500 to 7,200 revolutions
per minute. The head reads and writes data onto the spinning disk while flying
at a height of 2.0 microinches (.05 micron) at data transfer rates of 40 to 80
megabits per second. The combination of modern head and disk technologies
enables this drive to store data on 4,000 to 6,000 circumferential tracks per
radial inch on the disk with 75,000 to 110,000 bits of data per inch along each
track.
 
  Thin Film Disk Technology
 
     A thin film disk is composed of a substrate, generally aluminum, coated
with thin films capable of storing information in the form of magnetic patterns.
The manufacturing of thin film disks is a multi-step process using processes
similar to those used for the production of silicon wafers for semiconduc-
 
                                       30

tors. The manufacturing process involves the deposition of extremely thin,
uniform layers of magnetic film onto a substrate using a sputtering process, by
either a static or in-line system, similar to that used to coat silicon wafers.
The basic process consists of many interrelated steps and requires an extremely
clean environment. Minor deviations in the manufacturing process, minute
impurities in materials used, particulate contamination or other problems can
cause significant numbers of disks to be rejected, thereby causing significant
yield loss.
 
     The most significant technological challenges facing disk manufacturers
today are associated with market demand for increased storage capacity and
durability. An effective implementation of thin film technology to meet these
challenges must address various performance-related characteristics, including
magnetics, glide height, durability and static friction ("stiction").
 
     - Magnetics.  Coercivity, a measure of the magnetic strength of the disk,
       is expressed in Oersted ("Oe"). The magnetic strength of the disk is
       determined by the types of disk substrate and thin film materials used,
       substrate surface conditions before disk sputtering, and the conditions
       that exist during the sputtering process, including temperature, vacuum
       and possible sources of disk contamination. As areal density increases,
       higher coercivity is needed to permit sharper transitions between
       magnetized regions. This allows each bit of data to be stored in a
       smaller area, and therefore more data can be stored in the same disk
       area. Advanced drive designs currently require coercivities in the range
       of 1800 to 2200 Oe, compared to a range of 950 to 1200 Oe five years ago.
       The Company believes that most high-end disk drive manufacturers will
       require coercivities of 2000 to 2400 Oe by the end of 1996. HMT currently
       manufactures and sells disks in commercial quantities with coercivities
       ranging from 1900 to 2200 Oe, with more than 40% of the Company's
       revenues during the three months ended March 31, 1996 deriving from disks
       with coercivities of 2000 Oe and above. The Company is also currently
       producing small quantities of disks for use in customer development
       programs with coercivities of up to 2700 Oe.
 
     - Glide Height.  The glide height of the disk is the measure of the height
       at which the head can fly over the disk without hitting anything and is a
       standard used in the specification of the disk. The actual flying height
       of the head in the disk drive is higher than the glide height to provide
       a margin for safety. Glide height depends on the smoothness and flatness
       of the disk surface. The lower the disk head flies above the disk
       surface, the more accurately the head can read the magnetic signal,
       allowing a smaller magnetized region to store each bit of data and
       thereby contributing to increases in areal density. While the current
       industry standard glide height is 1.5 microinches, the Company expects
       that glide heights will decrease to 1.2 microinches during 1996. The
       Company currently manufactures and sells disks in commercial quantities
       with glide heights of 1.5 microinches and 1.2 microinches.
 
     - Durability Through Start/Stop Cycles.  In most hard disk drives, the head
       and disk come into contact when the disk drive is turned off and the head
       rests directly on the inner diameter of the disk. To prevent wear on the
       disk, a protective overcoat is deposited over the magnetic layer of the
       disk. However, the thickness of this overcoat must be minimized because
       this layer increases the distance of the head from the magnetic layer,
       thereby reducing the strength of the magnetic signal reaching the head.
       Customer specifications typically require 60,000 start/stop cycles for
       desktop PCs.
 
     - Stiction.  Stiction is the static friction that occurs when two smooth
       surfaces come into contact. In the case of hard disk drives, an extremely
       smooth disk surface enables lower glide heights and can enhance
       durability by reducing the friction which occurs when the head contacts
       the disk. However, if a disk is too smooth, stiction will cause the head
       to adhere to the disk surface when the drive is turned on and off,
       causing irreparable damage to the hard disk drive. Disk manufacturers
       minimize this problem primarily through texturizing the disk surface in a
       controlled manner.
 
                                       31
<PAGE>   34
 
     Disk manufacturers cannot simply address each performance characteristic
discretely because the interplay among characteristics significantly impacts the
overall performance of the disk. For example, a protective overcoat that yields
a highly durable disk may well reduce the disk's potential storage capacity.
 
  Challenges Facing the Disk Drive Industry
 
     Despite technological advances in components, including thin film disks,
and the prospects for continued data storage market growth, disk drive
manufacturers face a demanding marketplace. A strong competitive position is
best achieved through continual innovation. Improvements in product performance
characteristics, designed to meet the growing demands for increased storage
capacity, play an integral part in allowing the manufacturer to generate
acceptable gross margins. However, in the highly competitive disk drive
industry, other manufacturers have generally been able to develop comparable
products within a relatively short time. The likelihood of rapidly decreasing
profitability over the life cycle of any given product provides a strong
incentive for manufacturers to innovate. This results in extremely short product
cycles, currently estimated to be from nine to twelve months.
 
     Disk drive manufacturers participating in the high-end, high-capacity disk
drive market segment can realize higher gross margins by successfully addressing
the need for drives capable of supporting today's demand for high-performance,
value-added computing products. In this segment, which supplies products
incorporated into high-end PCs, network servers and workstations, users are less
price sensitive than typical home PC consumers because they have a more
compelling need for a value-added product. Because of the short product cycles
and the significant technology improvements incorporated into each new
generation of high performance disk drives, the need to be in the forefront of
technological advances is particularly great for companies competing in this
segment.
 
     Disk drive manufacturers can produce higher capacity products by putting
more disks in a drive or coupling a number of drives together in an array. These
approaches are limited by form factor constraints and technical complexity.
These are also relatively high cost solutions since the drive manufacturer is
adding more componentry. A more cost-effective solution is to develop a product
that can store more data using the same number of components. Thus, disk drive
manufacturers generally have relied on the development of new head technologies
and of thin film disks with improved areal density characteristics to support
generational advances in storage capacity and performance.
 
THE HMT APPROACH
 
     HMT focuses on providing value added technological solutions that meet the
demands of the high-end, high-capacity disk drive market. The Company develops,
manufactures and sells technologically advanced products designed to provide
improved performance, principally through achieving higher coercivities and
lower glide heights. The Company seeks to be a supplier to disk drive
manufacturers with a proven record for technological leadership because these
customers have the greatest ability to fully exploit the value of
technologically superior disks. By working with such high-end customers and
their head vendors, HMT can influence leading edge disk drive designs and earn a
strong position as a supplier of disks for these products.
 
STRATEGY
 
     The key elements of HMT's strategy are as follows:
 
     - Establish and Maintain Leadership in High-End Product Technology.  The
       Company focuses its development resources principally on performance
       improvements for disks sold to the high-end, high-capacity segment of the
       disk drive industry. In order to improve product performance
       characteristics, including magnetics, glide height, durability and
       stiction, HMT is continually engaged in efforts to enhance its
       proprietary technologies and processes. For example, efforts in the alloy
       and process development area, focusing largely on non-precious metal
       alloys, are directed toward improving disk coercivity above the 2500 Oe
       level.
 
                                       32
<PAGE>   35
 
     - Develop Collaborative Relationships with Leading Head and Disk Drive
       Manufacturers.  The Company works closely with head manufacturers
       developing new technologies, including TRI-PAD compatible and MR-head
       ready disks. This collaboration enables the parties to develop compatible
       products which can be effectively incorporated together into leading edge
       disk drives. HMT also seeks to establish strong relationships with its
       customers, enabling the Company to participate in establishing
       technological and design requirements for new products. The Company
       believes that close technical collaboration with its customers and their
       other suppliers during the design phase of new disk drives facilitates
       integration of the Company's products into new disk drives, improves the
       Company's ability to reach cost effective high volume manufacturing
       rapidly and enhances the likelihood that the Company will become a
       primary supplier of thin film disks for high performance disk drive
       products.
 
     - Develop Advanced Manufacturing Processes to Support Volume
       Production.  HMT develops advanced manufacturing processes directly on
       state-of-the-art production equipment. Developing manufacturing processes
       for new products directly on active production lines during the research
       and development phase increases the likelihood that the Company can
       quickly and efficiently transition to high volume commercial production
       of new products. The ability to implement new processes quickly also
       helps the Company meet its customers' increasingly rapid time-to-market
       demands and advances its goal of having its products designed into its
       customers' disk drives.
 
     - Expand Manufacturing Capacity.  Demand for the Company's thin film disks
       currently exceeds its manufacturing capacity. HMT has recently completed
       an expansion of manufacturing capacity in its current facility and
       announced plans to construct a new production facility at its Fremont,
       California site. In addition, the Company recently acquired an aluminum
       substrate manufacturing facility and related equipment located in Eugene,
       Oregon and has announced plans to enlarge that facility in order to
       increase substrate production and to add nickel plating and polishing
       capability. The Company expects that added capacity will enable it to
       improve its ability to meet the demands of current customers and position
       it to take advantage of additional market opportunities.
 
     - Maintain Strict Quality Control of Manufacturing Process.  HMT believes
       that its close attention to quality control results in a consistent
       product and high production yields and is key to its success. Attention
       to quality has the dual benefit of producing high performance disks and
       lowering the Company's cost of production. In addition, product quality
       is an essential factor in the supplier certification process of disk
       drive manufacturers. Two customers currently accept shipments of the
       Company's products directly to stock, which HMT believes indicates a high
       degree of customer confidence in HMT's ability to manufacture a
       consistently high quality product and which potentially reduces customer
       costs associated with disk supply.
 
PRODUCTS
 
     The Company provides a range of magnetic density points (coercivities),
glide heights and disk thicknesses. HMT currently manufactures and sells disks
in commercial quantities with coercivities ranging from 1900 to 2200 Oe and
glide heights of 1.5 microinches or less. The Company is also currently
producing small quantities of disks for use in customer development programs
with coercivities of up to 2700 Oe.
 
     The Company's product mix continually shifts as technological advances are
implemented in anticipation of demand for disks with improved performance
characteristics and the Company transitions production from less technologically
sophisticated disks still in active use. For example, during the three months
ended March 31, 1995, 1800 Oe and below products comprised 95.0% of total units
shipped. In the three months ended March 31, 1996, all products shipped were
1900 Oe and above, with more than 40% of the units shipped having coercivities
of 2000 Oe and above.
 
                                       33
<PAGE>   36
 
     The Company's disks are currently used by seven disk drive manufacturers in
nine different 3 1/2-inch disk drive products. Currently, these disks are
primarily used in disk drives with capacities ranging from 1.6 GB to 9 GB and
have storage capacity per disk ranging from 525 to 750 MB. The Company has the
technological capability to produce disks to fit standard form factors of
5 1/4-inches and below, although it currently produces only 3 1/2-inch disks.
 
MANUFACTURING AND QUALITY
 
     HMT believes that its internally developed proprietary and patented
manufacturing processes and state-of-the-art equipment, to which it has made
proprietary modifications, combined with its extensive expertise, currently
provide HMT with a technological advantage over competing independent thin film
disk manufacturers. HMT's expertise, processes and equipment also allow it to
develop new proprietary processes in response to customers' requirements for
improved product performance and to integrate new technologies into the
manufacturing process rapidly. The Company's production lines can be installed,
modified or expanded on a cost efficient basis. The use of a modular strategy
facilitates incremental capacity increases, efficient adaptation of
manufacturing equipment for new product processes and achievement of high volume
manufacturing capacity for new products on a timely basis.
 
  Manufacturing Process
 
     The Company's manufacturing process is briefly summarized as follows:
 
     Chamfer, Grind, Bake and Wash.  The initial input to the production of a
thin film disk is an aluminum blank that can be procured from a number of
sources. To create specialized aluminum alloy substrates, the manufacturer
chamfers the sharp inner and outer edges of the blank, rough grinds the blank to
achieve flatness, bakes the blank to bring out surface roughness, final grinds
to remove surface defects and improve surface finish, and then washes the blank
to remove particles. HMT manufactures a portion of its requirements for these
substrates, which must be flat, smooth and free of surface defects, and
purchases the balance of its requirements from independent vendors.
 
     Plate, Polish, Texture and Wash.  Aluminum substrates are plated with
electro-less nickel, a non-magnetic layer critical to corrosion resistance that
strengthens the disk and improves durability. The Company currently performs
most of its nickel plating in-house. Disks are then polished to produce a mirror
smooth surface. Polishing enhances the nickel surface, reducing its roughness,
while maintaining the overall flatness of the disk. The Company's texturizing
process, a highly automated patented process, produces a controlled roughness on
the disk's surface to improve its stiction characteristics. The final step in
these front-end processes is washing to present a clean disk surface. Subsequent
processes occur in class 10 clean rooms.
 
     Sputter, Dip Lube and Kiss Buff.  The sputter process uses equipment and a
process, similar to that used in silicon wafer fabrication, in which layers of
materials are deposited on the disk through a vacuum sputtering process. The
chrome and magnetic layers determine the magnetic properties of the disk. The
carbon layer is a protective overcoat. After sputtering, a microscopic layer of
lubrication is applied to the disk's surface to improve durability and reduce
surface friction. After lubrication, a surface finishing step is applied,
commonly referred to as kiss buff or tape burnish.
 
     Glide/Certify.  In the test and certification process each finished disk is
electronically screened and certified as acceptable based on the customer's
specifications. A robotically controlled tester electronically tests for glide
performance. The tester then writes information onto the disk, reads it back and
erases it, simulating performance in the customer's disk drive. Each disk is
tested for parametrics, errors in the read/erase process and surface defects.
 
     The conversion of a specialized aluminum alloy substrate into a final
product requires three to five days.

                     THE THIN FILM DISK PRODUCTION PROCESS
 
  Quality Assurance
 
     HMT has a dedicated quality assurance group. The Company believes that its
quality assurance program allows it to realize superior product yields and
consistently produce a quality product. Because a high quality product is
critical to achieving strong operating results and high customer satisfaction,
HMT's emphasis on this area will remain a top priority. The organization
consists of four separate groups:
 
     - Application Engineering.  The Application Engineering group is
       responsible for reviewing customer requirements and specifications by
       conducting specification reviews and soliciting customer and internal
       manufacturing feedback. Other functions include correlating and evalu-
 
                                       35
<PAGE>   38
 
       ating the results of HMT and customer testing, generating standards and
       performing source audits.
 
     - Supplier Quality Engineering.  Because quality assurance is a critical
       aspect of the Company's strategy, the emphasis on quality must extend to
       the supplier level. The Supplier Quality Engineering group is responsible
       for ensuring incoming product quality through auditing suppliers,
       reviewing process data, establishing internal specifications and creating
       quality procedures and practices. The group also establishes material
       specifications, supplier benchmarking and standards for qualification of
       the supplier base.
 
     - Reliability and Process Engineering.  The Reliability and Process
       Engineering group is responsible for performing ongoing reliability
       testing, process improvement testing and new product development testing.
       Specific functions involve statistical process control analysis, gauge
       repeatability and reproducibility studies, equipment calibration, process
       qualification improvements and in-process quality audits.
 
     - Customer Support.  The Customer Support group acts as liaison between the
       customer and the Company's manufacturing organization. All customer
       concerns and issues are handled through the group. Other responsibilities
       include corrective action requests, non-conforming material reviews,
       return material authorizations and document control.
 
  Manufacturing Facilities and Capacity
 
     The Company's manufacturing facilities, distribution center and
administrative offices are located in Fremont, California. The Company's Fremont
facility received ISO 9001 certification in May 1996. The Company operates
fourteen production scale sputtering lines for production and development of
products. A typical sputtering line consists of one sputtering machine and
associated equipment, such as texturizers, lubricators, glide testers and
certifiers. The Company's facilities, which currently operate seven days a week,
24 hours per day, are close to full capacity. The Company has recently announced
plans to construct a new production facility at its Fremont, California site, in
which it plans to install up to 16 additional production scale sputtering lines.
The Company has also recently acquired an aluminum substrate manufacturing
facility and related equipment located in Eugene, Oregon, and has announced
plans to enlarge that facility in order to increase substrate production and to
add nickel plating and polishing capability.
 
   
     Because the Company has been operating at close to full capacity, growth in
the Company's net sales depends on the successful expansion by the Company of
its manufacturing capacity. Although the Company has improved its production
capacity in its existing facility, significant additional increases will depend
on successfully developing the new production facility in Fremont and on
successfully enlarging the Eugene, Oregon facility to provide an increased
internal supply of nickel plated and polished substrates. There can be no
assurance that the Company will be able to successfully increase capacity and
the failure to do so could have a material adverse effect of the Company's
business, operating results and financial condition.
    
 
TECHNOLOGY
 
     The Company believes that there are a number of factors that are key to
establishing and maintaining an advanced technology position. The Company is
optimizing non-precious metal alloys, based on a cobalt/chromium/tantalum alloy,
for future products with coercivities that can support foreseeable demand for
increased storage capacity using relatively inexpensive materials. The Company
also has extensive expertise in the deposition of these and other alloys onto
disks. The Company uses state-of-the-art static sputtering machines in the
development and production of disks. Static machines differ from in-line, pallet
machines used by some other disk manufacturers in a number of important
respects. Static sputtering machines process one stationary disk at a time,
allowing for greater control of alloy deposition and minimizing spatial and
temperature variation; use isolated process chambers, permitting the
manufacturer to control and optimize each process step separately;
 
                                       36
<PAGE>   39
 
and do not require a pallet, reducing the risk of contamination of the disk
surface during processing. The Company has further enhanced the performance of
sputtering equipment supplied by vendors through internally developed,
proprietary and patented modifications.
 
     The Company believes its unique tribology approach, which minimizes
detrimental interaction between the head and disk, is another area of strength.
The method involves balancing the inter-relationship between texturizing, carbon
overcoating and lubrication. The Company's patented graded zone texture process
allows the Company to produce a rougher texture at the disk's inner diameter,
while creating a smoother surface on the remainder of the disk. This process
provides increased protection where the head most often comes into contact with
the disk, while also minimizing the distance between the head and the disk
magnetics in other regions of the disk where data is stored and read. A
nitrogen-containing carbon overcoat offers superior wear resistance. Application
of the Company's in-house blended lubricant results in disks that can withstand
an extreme range of temperature and humidity conditions. These additional layers
must be thick enough to achieve the desired protection of the disk and thin
enough to minimize the distance between the head and the magnetic layer of the
disk. The Company believes that its application of these technologies, with
particular attention to the inter-relationship between the technologies and
their combined effect on disk performance, have enabled it to develop
competitive high-capacity disks.
 
     The Company also devotes considerable resources to developing disks for
drives utilizing new head technology. Head technology, traditionally based on
flying inductive heads that combine the read and write function within one head,
is undergoing significant evolution. Two important new technologies, proximity
recording and MR-heads, have emerged and over time are expected to replace
traditional inductive technology. The Company believes that proximity recording,
such as TRI-PAD or similar technology, which is an extension of current
inductive technology that, by design, allows a portion of the head to have
intermittent contact with the disk, will be an important technology for the next
several years. MR-head technology segregates the read and write function to
different elements of the head. By physically disconnecting the writing and
readback processes each can be individually tuned for optimized performance. The
Company expects that the superior performance offered by MR technology will make
it the dominant head technology of the future. In order to take advantage of the
technological potential of these new head technologies and enable the Company to
play a role in setting design specifications for the disk drive product, HMT
works directly with head manufacturers to develop compatible disks. The Company
has demonstrated the ability to produce disks for the new head formats through
the use of non-precious metal alloys, modified equipment and optimized
processes.
 
     The Company believes that its materials science expertise and ongoing
commitment to developing new technologies is critical to remaining competitive
and achieving desired operating results. The Company expects its research and
development effort to remain focused on alloy and process development, substrate
finish and texture, overcoat development, and compatibility with advanced
recording concepts. As it has done in the past, the Company intends to conduct
many of its development programs directly on active production lines,
facilitating transition to high volume commercial production and minimizing
development expense. During the fiscal years 1994, 1995 and 1996, the Company
incurred $2.8 million, $3.1 million, and $3.8 million, respectively, of research
and development expenses. The Company believes that its future success depends
on its ability to continue to enhance its existing products and to develop new
products.

CUSTOMERS, SALES AND SUPPORT
 
     The Company sells its products directly to independent OEM disk drive
manufacturers for incorporation primarily into hard disk drives which are
marketed under the manufacturers' own labels. The following table sets forth the
percentage of net sales attributable to sales to the Company's principal
customers in the three months ended March 31, 1996, fiscal 1996 and fiscal 1995.

     The Company's other customers during the three months ended March 31, 1996
included Iomega, Quantum and Samsung. Iomega utilizes the disks in its removable
media hard disk drives. Due to cessation of its high-end manufacturing
operations, Quantum's high-end products are expected in the future to be
manufactured by Matsushita Kotobuki Electronics Industries ("MKE"), and the
Company is currently qualifying its products with MKE. The Company recently
began shipping products to Samsung. Due to the rapid and frequent development of
new disk drive products, it is common in the industry for the relative mix of
customers and products to change rapidly, even from quarter to quarter.
 
   
     The Company has generally sold its products to customers pursuant to
purchase orders and similar short-term arrangements. In June 1996, the Company
entered into a long-term supply agreement with Maxtor covering the supply of
disks to Maxtor over the next five years. While this agreement contemplates a
significant increase in the purchases of disks by Maxtor from current levels, it
is subject to a number of conditions and qualifications; and there can be no
assurance that Maxtor will in fact remain a significant customer during the term
of the agreement.
    
 
     The Company believes that close technical collaboration with its customers
and their other suppliers during the design phase of new disk drives facilitates
integration of the Company's products into new disk drives, improves the
Company's ability to rapidly reach cost effective high volume manufacturing and
enhances the likelihood that the Company will become a primary supplier of thin
film disks for new disk drive products. However, the design-in process is
ongoing and recurs frequently, and the Company must compete for participation in
each new product program, even those of existing customers.
 
     The Company's customer sales and service efforts are an integral part of
maintaining strong customer relations. The sales and service organization
processes requests from customers concerning product needs and acts to mobilize
the Company's resources to fulfill customer requests.
 
     Although the Company has broadened its customer base, there are a
relatively small number of disk drive manufacturers, and the Company expects
that its dependence on a few customers will continue in the future.
Additionally, there is the possibility that one or more of the Company's
customers could develop or expand their ability to produce thin film disks
internally and, as a result, could reduce the level of purchases or cease
purchasing from the Company or could sell thin film disks in competition with
the Company. There has also been a trend toward consolidation in the disk drive
industry that the Company expects to continue. If any of the Company's customers
or competitors were to combine and rationalize suppliers and competitive product
lines, the Company's business, results of operations and financial condition
could be materially adversely affected.
 
BACKLOG
 
     The Company's sales are generally made pursuant to purchase orders that are
subject to cancellation, modification, quantity reductions or rescheduling
without significant penalties. The Company's backlog of purchase orders

typically provide the Company with forecasts of expected requirements for the
next three to six months and submit purchase orders 60 to 90 days in advance of
shipment dates. Because these purchase orders may be modified or rescheduled by
customers on short notice and without penalty, the Company does not believe that
its backlog as of any particular date should be considered indicative of sales
for any future period.
 
COMPETITION
 
     Competitors in the thin film disk industry fall into three groups: U.S.
non-captive manufacturers, Japan-based manufacturers and U.S. captive
manufacturers. Historically each of these groups has supplied approximately
one-third of the worldwide thin film disk unit output. The Company's primary
U.S. non-captive competitors are Akashic, Komag and StorMedia. Japan-based
competitors include Fuji, Mitsubishi, Showa Denko and Hoya. Certain of these
companies have significantly greater financial, technical and marketing
resources than the Company. In addition, U.S. captive manufacturers, which
include certain computer manufacturers, as well as disk drive manufacturers such
as Seagate, an affiliate of Maxtor and Western Digital, manufacture disks or
plan to manufacture disks for their internal use as part of their vertical
integration programs. These companies could increase their internal production
and reduce or cease purchasing from independent disk suppliers such as the
Company. In the event of an oversupply of disks, these customers are likely to
utilize their internal capacity prior to purchasing disks from independent
manufacturers such as the Company. Moreover, while captive manufacturers have,
to date, sold only nominal quantities of thin film disks in the open market,
there can be no assurance that such companies will not in the future do so in
direct competition with the Company. Furthermore, there can be no assurance that
other current and potential customers will not acquire or develop capacity to
produce thin film disks for internal use, or that disk manufacturing capacity
will not exceed demand. Any such changes could have a material adverse effect on
the Company's business, operating results and financial condition. Announcement
or implementation of any of the following by the Company's competitors could
have a material adverse effect on the Company's business, operating results and
financial condition: changes in pricing, product introductions, increases in
production capacity, changes in product mix and technological innovation.
 
     The market for thin film disk products is highly competitive, and the
Company expects competition to increase in the future. The Company believes that
the principal competitive factors affecting this market include performance,
quality, delivery capability and price. The Company believes that its products
compete favorably in the high-end segment of the market that it serves,
especially with respect to performance and quality. The thin film disk industry
is characterized by short product life cycles, ranging from nine to twelve
months. As a result, the Company must continually anticipate, and adapt its
products to meet, demand for increased storage capacity. There can be no
assurance that in the future the Company will be able to manufacture products on
a timely basis with the quality and features necessary in order to remain
competitive. In addition, the development of technologically innovative products
requires substantial investments in research and development. Specifically, the
thin film disk industry is characterized by intense price competition. While the
Company believes that consumers in the high-end high-capacity segment of the
market in which the Company operates are less sensitive to price, the Company
has experienced pricing pressures in the past, and there can be no assurance
that the Company will not experience increased price competition in the future.
Pricing pressure has included, and may in the future include, demands for
discounts, long-term supply commitments and extended payment terms. Any increase
in price competition could have a material adverse effect on the Company's
business, operating results and financial condition.
 
INTELLECTUAL PROPERTY AND PROPRIETARY RIGHTS
 
     Although the Company attempts to protect its intellectual property rights
through patents, copyrights, trade secrets and other measures, it believes that
its success will depend more upon the innovation, technological expertise and
marketing abilities of its employees. There can be no assurance that the Company
will be able to protect its technology adequately or that competitors will not
be able
 
                                       39
<PAGE>   42
 
to develop similar technology independently. The Company has 26 patents and 15
pending patent applications in the United States. In addition, the Company has
nine foreign patents. Patents may not be issued with respect to the Company's
pending patent applications, and its issued patents may not be sufficiently
broad to protect the Company's technology. No assurance can be given that any
patent issued to the Company will not be challenged, invalidated or circumvented
or that the rights granted thereunder will provide adequate protection to the
Company's products. In addition, the Company has only limited patent rights
outside the United States and the laws of certain foreign countries may not
protect the Company's intellectual property rights to the same extent as do the
laws of the United States.
 
     The Company may from time to time be notified by third parties that it may
be infringing patents owned by such third parties. If necessary, the Company may
have to seek a license under such patents or modify its products and processes
in order to avoid infringement of such patents. There can be no assurance that
such a license would be available on acceptable terms, if at all, or that the
Company could so avoid infringement of such patents, in which case the Company's
business, operating results and financial condition could be materially
adversely affected. The Company and one of its customers have been contacted by
Virgil L. Hedgcoth concerning the use of certain disk preparation techniques
allegedly patented by Mr. Hedgcoth (the "Hedgcoth Patents"). The Company
generally provides its customers with indemnification for damages sustained by a
customer as a consequence of patent infringement claims arising out of use of
the Company's products and agrees to defend its customers against such claims.
Based on its review of the Hedgcoth Patents, the Company believes that it does
not use the techniques described in the Hedgcoth Patents. The Company is aware
that another manufacturer is currently litigating the validity of the Hedgcoth
Patents. Should they be upheld, there can be no assurance that Mr. Hedgcoth will
not make a claim against the Company, in which case the Company could be
required to defend its position.
 
     Litigation may be necessary to enforce the Company's patents, copyrights or
other intellectual property rights, to protect the Company's trade secrets, to
determine the validity and scope of the proprietary rights of others, or to
defend against claims of infringement or claims for indemnification resulting
from infringement claims by third parties. Such litigation, even if successful,
could result in substantial costs and diversion of resources and could have a
material adverse effect on the Company's business, operating results and
financial condition.
 
SOURCES OF SUPPLY
 
     The Company relies on a limited number of suppliers for many materials used
in its manufacturing processes, including substrates, texturizers, plating
chemicals, abrasive tapes and slurries, certifier heads, sputter targets and
certain other materials. In general, the Company seeks to have two or three
suppliers for its requirements; however, there can be no assurance that the
Company can secure more than one source for all of its materials requirements in
the future or that its suppliers will be able to meet the Company's requirements
on a timely basis or on acceptable terms. Shortages have occurred in the past
and there can be no assurance that shortages will not occur in the future, or
that materials will not be available only with longer lead times. Moreover,
changing suppliers for certain materials, such as lube or buffing tape, would
require that the product be requalified with each customer. Requalification
could prevent an early design-in, or could prevent or delay continued
participation in disk drive programs for which the Company's products have been
qualified. In addition, long lead times are required to obtain many materials.
Regardless of whether these materials are available from established or new
sources of supply, these lead times could impede the Company's ability to
quickly respond to changes in demand and product requirements. Furthermore, a
significant increase in the price of one or more of these materials could
adversely affect the Company's business, operating results and financial
condition. While the Company has implemented procedures to monitor the quality
of the materials received from its suppliers, there can be no assurance that
materials will meet the Company's specifications and will not adversely impact
manufacturing yields or cause other production problems. For example, in the
quarter ended March 31, 1995, the Company's operating
 
                                       40
<PAGE>   43
 
results were adversely affected by chlorine contamination of its thin film disk
products that it believes resulted from chlorine contamination of disk carriers
provided by one of its suppliers. In addition, there are only a limited number
of providers for thin film disk manufacturing equipment, such as sputtering
machines, glide testers and certifiers, and ordering additional equipment for
replacement or expansion requires long lead times, limiting the rate and
flexibility of capacity expansion. Any limitations on, or delays in, the supply
of materials or equipment could disrupt the Company's production volume and
could have a material adverse effect on the Company's business, operating
results and financial condition.
 
ENVIRONMENTAL REGULATION
 
     The Company's operations and manufacturing processes are subject to certain
environmental laws and regulations, which govern the Company's use, handling,
storage, transportation, disposal, emission and discharge of hazardous materials
and wastes, the pre-treatment and discharge of process waste waters and its
emission of air pollutants. The Company has from time to time been notified of
minor violations of environmental laws and regulations, including its waste
water discharge permits, San Francisco Bay Area air quality regulations and
hazardous material regulations including releases of hazardous materials. These
violations have been corrected in all material respects without undue expense.
Environmental laws and regulations, however, may become more stringent over time
and there can be no assurance that the Company's failure to comply with either
present or future laws or regulations would not subject the Company to
significant compliance expenses, production suspension or delay, restrictions on
expansion or the acquisition of costly equipment.
 
EMPLOYEES
 
     As of March 31, 1996, the Company had 651 full-time employees, with 542 in
manufacturing, 37 in research and development, 32 in quality assurance and 40 in
administration and marketing. The Company believes it generally has good
relations with its employees. None of the Company's employees are represented by
a labor union, and the Company has never experienced a work stoppage. The
Company believes that attracting and motivating skilled technical personnel is
vital to its success. Although competition for such personnel is intense, the
Company believes that it has not historically experienced difficulties in
attracting personnel that are significantly different from those experienced by
its competitors.
 
PROPERTIES
 
     The Company owns a 57,776 square foot building, used for manufacturing and
administration, on approximately 4.3 acres of land in Fremont, California, and
an adjacent five acre parcel. The Company has recently announced its intention
to build an additional 120,000 square foot manufacturing and administrative
facility on this site. The Company leases an adjacent 50,400 square foot
building used primarily for manufacturing under a lease that expires in December
1998 with four five-year extension options. The Company also leases 11,424
square feet of space in a nearby building that it uses for a distribution center
under a lease agreement that expires in September 1998, subject to an option to
extend for an additional five years. A smaller facility used for administrative
offices has a lease term ending March 1997.
 
     On May 9, 1996, the Company purchased a 36,400 square foot building on
approximately 4.6 acres in Eugene, Oregon. The Company has announced plans to
enlarge this building, which is used for manufacturing and administration, to
75,000 square feet.
 
     The Company's Fremont facilities, which currently account for all of its
finished disk production, are located near major earthquake faults. Disruption
of operations for any reason, including power failures, work stoppages or
natural disasters such as fire, floods or earthquakes, could materially
adversely affect the Company's business, operating results and financial
condition.

                                    GLOSSARY
 
AREAL DENSITY:  The number of bits of data stored per unit of area.
 
BIT:  The basic unit of storage of information in a computer system. Bits are
represented by the presence or absence of changes in orientation of the magnetic
domains along a track on the storage media.
 
BYTE:  Equal to eight bits.
 
CHAMFER:  The process of cutting the sharp edges from the inner and outer edges
of an aluminum blank.
 
COERCIVITY:  A measure of the magnetic strength of the disk which is expressed
in Oersteds.
 
DISK SPUTTERING LINES:  A sputtering system and related equipment such as
plating, polishing, texturizing, lubrication and test equipment as well as
related handling equipment.
 
GIGABYTE:  Equal to one billion bytes or one thousand megabytes.
 
GLIDE HEIGHT:  The height at which the head can fly over the disk without
hitting anything. The glide height is dependent on the smoothness and flatness
of the disk.
 
HEAD OR DISK DRIVE HEAD:  Small magnetic transducer that flies above the surface
of the disk and performs the functions of reading and writing data on the disk.
 
INDUCTIVE WRITING AND READING HEADS:  Refers to heads which use a single element
for both the writing and reading process. In the writing process, a current
induces an alternating magnetic field at the magnetic tips of the head. In the
reading process, the same element senses the magnetic field from the written
bits of data and thereby induces an electrical current.
 
MAGNETO-RESISTIVE (MR) HEADS:  Recording heads that use an inductive thin film
element to write data on to the media and read the data with a separate
magneto-resistive element. The use of a separate but much more sensitive read
element permits data to be recorded and, subsequently, read at much higher track
densities than inductive thin film head technology.
 
MEGABYTE:  Equal to one million bytes.
 
MICROINCH:  One millionth of an inch.
 
MICRON:  One millionth of a meter.
 
NETWORK SERVER OR SERVER:  A computer generally configured for the support of
concurrent multi-user applications. The server is generally a storage repository
of software and data.
 
OERSTED (OE):  A unit of magnetic strength.
 
PROXIMITY RECORDING:  Extension of traditional inductive writing/reading
technology which improves performance by bringing transducer into direct contact
with disk.
 
SPUTTERING:  A complex vacuum deposition process used to deposit multiple thin
film layers on a disk.
 
STICTION:  The static friction that occurs when two smooth surfaces come into
contact. A common example is a coin on a wet counter.
 
SUBSTRATES:  The disk material (typically aluminum) onto which the thin layers
of material are sputtered.
 
THIN FILMS:  For magnetic disks, films with thickness measured in microinches
(millionths of an inch).
 
THIN FILM DISK OR DISK:  A disk incorporating a thin magnetic film capable of
storing information in the form of magnetic patterns written and detected by a
separate magnetic head within a disk drive.
 
TRIBOLOGY:  Refers to the mechanical interaction between the recording head and
the disk.
 
YIELD:  A measure of manufacturing efficiency; the percent of acceptable product
obtained from a specific manufacturing process(es).

(1) Based on 12,098,150 options granted in fiscal 1996.
    
 
(2) All stock options were granted with exercise prices equal to the fair market
     value, as determined by the Board of Directors, on the grant date.
 
(3) These amounts are based on compounded annual rates of stock price
     appreciation of five and ten percent over the 10-year term of the options,
     are mandated by the rules of the Securities and Exchange Commission and are
     not indicative of expected stock performance. Actual gains, if any, on
     stock option exercises are dependent on future performance of the Common
     Stock, overall market conditions, as well as the option holders continued
     employment throughout the vesting period. The amounts reflected in this
     table may not necessarily be achieved or may be exceeded. The indicated
     amounts are net of the option exercise price but before taxes that may be
     payable upon exercise.
 
(4) Of the options, 30.4% vested immediately upon grant, and the remaining 69.6%
     of the options vest monthly over a four-year period on a pro-rata basis.
 
(5) These options vest monthly over a four-year period on a pro-rata basis
     beginning on December 31, 2000. The options have performance-based vesting
     provisions, which accelerate the vesting of the options based on the
     attainment of certain performance benchmarks.

EMPLOYEE BENEFIT PLANS
 
     1995 Management Stock Option Plan and 1995 Stock Option Plan.  In November
1995, the Board of Directors adopted and the stockholders approved the 1995
Management Stock Option Plan (the "1995 Management Plan") and the 1995 Stock
Option Plan (the "1995 Plan," and together with the 1995 Management Plan, the
"Stock Plans") and reserved 12,400,000 shares of Common Stock for issuance under
the Stock Plans. The Stock Plans provide for the grant to employees of the
Company of incentive stock options within the meaning of Section 422 of the
Internal Revenue Code of 1986, as amended (the "Code"), and for the grant to
employees, directors and consultants of the Company of nonstatutory stock
options. As of March 31, 1996, the Company had granted options to purchase an
aggregate of 12,284,150 shares of Common Stock, of which options to purchase
3,917,723 shares remained outstanding, and an aggregate of 115,850 shares
remained available for grant.
 
     The Stock Plans are administered by the Compensation Committee of the Board
of Directors, which determines the terms of any option granted, including the
exercise price, number of shares subject to the option and the exercisability
thereof. No option may be transferred by the optionee other than by will or the
laws of descent or distribution or, in certain limited instances, pursuant to a
qualified domestic relations order.
 
                                       47
<PAGE>   50
 
     The term of a stock option granted under the Stock Plans generally may not
exceed 10 years. The exercise price of options granted under the Stock Plans is
determined by the Board of Directors, but in the case of an incentive stock
option cannot be less than 100% of the fair market value of the Common Stock on
the date of grant or, in the case of 10% stockholders, not less than 110% of the
fair market value of the Common Stock on the date of grant. Shares covered by
currently outstanding options under the Stock Plans typically vest at the rate
of 1/4 of the shares subject to the option on the first anniversary of the date
of grant and 1/48 of such shares at the end of each calendar month thereafter.
 
     Certain of the shares exercisable under the 1995 Management Plan have a
performance accelerated vesting feature. The remaining unvested shares vest upon
the achievement of certain specified performance goals. Any shares that do not
become subject to the acceleration feature will vest over a four-year period at
a rate of 1/48 of such shares at the end of each calendar month beginning on
December 31, 2000.
 
     Upon any merger, consolidation or similar transaction in which the Company
is not the surviving corporation, all outstanding awards under the Stock Plans
shall either be assumed or substituted by the surviving entity. If the surviving
entity determines not to assume or substitute such options, the time during
which such options may be exercised will be accelerated and the options
terminated if not exercised prior to the transaction, except that those options
granted under the 1995 Management Plan that contain a vesting acceleration
feature will accelerate upon such a change in control only if the consideration
received in connection with the transaction equals or exceeds specified
thresholds.
 
     The Board of Directors determined that no further options would be granted
under the Stock Plans after completion of the initial public offering.
 
     1996 Equity Incentive Plan.  In January 1996, the Board of Directors
adopted and in February 1996 the stockholders approved the 1996 Equity Incentive
Plan (the "Incentive Plan") and reserved 3,000,000 shares of Common Stock for
issuance under the Incentive Plan, less shares granted under the 1996
Non-Employee Directors' Stock Option Plan. The Incentive Plan provides for
grants of incentive stock options to employees (including officers and employee
directors) and nonstatutory stock options, restricted stock purchase awards,
stock bonuses and stock appreciation rights to employees (including officers and
employee directors) and consultants of the Company. As of March 31, 1996, the
Company had not granted any options under the Incentive Plan. The Incentive Plan
is administered by the Compensation Committee, which determines recipients and
types of awards to be granted, including the exercise price, number of shares
subject to the award and the exercisability thereof.
 
     The term of a stock option granted under the Incentive Plan generally may
not exceed 10 years. The exercise price of options granted under the Incentive
Plan is determined by the Board of Directors, but, in the case of an incentive
stock option, cannot be less than 100% of the fair market value of the Common
Stock on the date of grant or, in the case of 10% stockholders, not less than
110% of the fair market value of the Common Stock on the date of grant. Options
granted under the Incentive Plan to new employees and consultants generally will
vest at the rate of 1/4 of the shares subject to option on the first anniversary
of the date of grant and 1/48th of such shares at the end of each calendar month
thereafter. No option may be transferred by the optionee other than by will or
the laws of descent or distribution or, in certain limited instances, pursuant
to a qualified domestic relations order. An optionee whose relationship with the
Company or any related corporation ceases for any reason (other than by death or
permanent and total disability) may exercise options in the three-month period
following such cessation (unless such options terminate or expire sooner by
their terms) or in such longer period as may be determined by the Board of
Directors.
 
     Shares subject to options which have lapsed or terminated may again be
subject to options granted under the Incentive Plan. Furthermore, the Board of
Directors may offer to exchange new options for existing options, with the
shares subject to the existing options again becoming available for grant under
the Incentive Plan. In the event of a decline in the value of the Company's
Common Stock, the Board of Directors has the authority to offer optionees the
opportunity to replace outstanding higher priced options with new lower priced
options.
 
                                       48
<PAGE>   51
 
     Restricted stock purchase awards granted under the Incentive Plan may be
granted pursuant to a repurchase option in favor of the Company in accordance
with a service vesting schedule determined by the Board. The purchase price of
such awards will be at least 85% of the fair market value of the Common Stock on
the date of grant. Stock bonuses may be awarded in consideration for past
services without a purchase payment. Stock appreciation rights authorized for
issuance under the Incentive Plan may be tandem stock appreciation rights,
concurrent stock appreciation rights or independent stock appreciation rights.
 
     Upon any merger, consolidation or similar transaction in which the Company
is not the surviving corporation, all outstanding awards under the Incentive
Plan shall either be assumed or substituted by the surviving entity. If the
surviving entity determines not to assume or substitute such awards, the time
during which such awards may be exercised shall be accelerated and the awards
terminated if not exercised prior to the transaction. The Incentive Plan will
terminate in January 2006, unless terminated sooner by the Board of Directors.
 
     Employee Stock Purchase Plan.  In January 1996, the Board of Directors
adopted and in February 1996 the stockholders approved the Employee Stock
Purchase Plan (the "Purchase Plan") covering an aggregate of 500,000 shares of
Common Stock. The Purchase Plan is intended to qualify as an employee stock
purchase plan within the meaning of Section 423 of the Code. Under the Purchase
Plan, the Board of Directors may authorize participation by eligible employees,
including officers, in periodic offerings following the adoption of the Purchase
Plan. The offering period for any offering will be no more than 27 months.
 
     Employees are eligible to participate if they are employed by the Company,
or an affiliate of the Company designated by the Board of Directors, for at
least 20 hours per week and are employed by the Company or a subsidiary of the
Company designated by the Board of Directors for at least five months per
calendar year. Employees who participate in an offering can have up to 15% of
their earnings withheld pursuant to the Purchase Plan. The amount withheld will
then be used to purchase shares of the Common Stock on specified dates
determined by the Board of Directors. The price of Common Stock purchased under
the Purchase Plan will be equal to 85% of the lower of the fair market value of
the Common Stock on the commencement date of each offering period or the
specified purchase date. Employees may end their participation in an offering at
any time during the offering period. Participation ends automatically on
termination of employment with the Company.
 
     Upon any merger, consolidation or similar transaction in which the Company
is not the surviving corporation, the Board of Directors has discretion to
provide that each right to purchase Common Stock will be assumed or an
equivalent right substituted by the surviving entity, or the Board may shorten
the offering period and provide for all sums collected by payroll deductions to
be applied to purchase stock immediately prior to such merger or other
transaction. The Purchase Plan will terminate at the Board's discretion. The
Board has the authority to amend or terminate the Purchase Plan, subject to the
limitation that no such action may adversely affect any outstanding rights to
purchase Common Stock.
 
     1996 Non-Employee Directors' Stock Option Plan.  In January 1996, the Board
adopted and in February 1996 the stockholders approved the 1996 Non-Employee
Directors' Stock Option Plan (the "Directors' Plan") to provide for the
automatic grant of options to purchase shares of Common Stock to non-employee
directors of the Company (other than employees or affiliates of Summit Partners,
L.P. or Hitachi Metals) and reserved 3,000,000 shares of Common Stock for
issuance under the Directors' Plan, less shares granted under the Incentive
Plan. As of March 31, 1996, no options had been granted under the Directors'
Plan. The Directors' Plan is administered by the Board of Directors, unless the
Board delegates administration to a committee comprised of members of the Board.
 
     Pursuant to the terms of the Directors' Plan, each director of the Company
not otherwise employed by the Company and who is first elected as a non-employee
director after the completion of this offering (other than employees or
affiliates of Summit Partners, L.P. or Hitachi Metals) automatically will be
granted an option to purchase 8,000 shares of Common Stock upon such election.
Each director who continues to serve as a non-employee director (other than
employees or affiliates of
 
                                       49
<PAGE>   52
 
Summit Partners, L.P. or Hitachi Metals) will be granted an additional option to
purchase 2,000 shares of Common Stock on each anniversary of the date of his or
her initial grant or, in the case of current non-employee directors, annually
commencing with the fourth anniversary of the date of this Prospectus.
 
     The term of stock options granted under the Directors' Plan generally may
not exceed 10 years. The exercise price of options granted under the Directors'
Plan will be equal to 100% of the fair market of the Common Stock on the date of
grant. Options granted under the Directors' Plan generally vest at the rate of
1/4 of the shares subject to the option on the first anniversary of the date of
grant and 1/48 of such shares at the end of each calendar month thereafter.
 
     Upon any merger, consolidation or similar transaction, the time during
which such options may be exercised will be accelerated and the options
terminated if not exercised prior to the transaction. The Directors' Plan will
terminate in January 2006, unless earlier terminated by the Board.
 
     401(k) Plan.  Effective January 1, 1992, the Company adopted a
tax-qualified employee savings and retirement plan (the "401(k) Plan") covering
all of the Company's employees who have attained the age of 21 and have
completed six months of service with the Company. Pursuant to the 401(k) Plan,
employees may elect to reduce their current compensation by up to the lesser of
15% of eligible compensation or the annual statutory limit ($9,500 in 1996) and
have the amount of such reduction contributed to the 401(k) Plan. The 401(k)
Plan permits, but does not require, a Company matching contribution equal to the
employee's deferred amount, generally up to a maximum of 4% of such employee's
annual compensation. The employee's contributions are fully vested and
nonforfeitable at all times. The Company's matching contributions, if any, vest
at a rate of 100% after the two years of service. The trustee under the 401(k)
Plan, at the discretion of each participant, invests the assets of the 401(k)
Plan in any of several investment options. The 401(k) Plan is intended to
qualify under Section 401 of the Code so that contributions by employees to the
401(k) Plan, and income earned on plan contributions, are not taxable to
employees until withdrawn, and so that the contributions by employees will be
deductible by the Company when made.
 
     Severance Plan.  In January 1996, the Company adopted an Executive
Severance Plan (the "Severance Plan") providing for certain benefits to
executive officers of the Company in the event an executive's employment is
involuntarily terminated without cause (generally meaning without any misconduct
on the executive's part) or that the executive voluntarily terminates employment
with good reason (generally meaning that the executive's responsibilities, title
or compensation was materially reduced). Upon the occurrence of such an event,
the Severance Plan provides for salary continuation for a period no greater than
one year. In addition, the Severance Plan provides for continued health benefits
coverage to the extent permitted by the Consolidated Omnibus Budget
Reconciliation Act of 1985 and the Company's group health policies.
 
     Bonus Plan.  The Company has a discretionary bonus program for certain
designated key employees of the Company, including all executive officers,
pursuant to which such employees are paid cash bonuses based upon the attainment
of certain specified corporate goals for the year established by the Board of
Directors. The amount of the bonus to which each such employee is entitled is
determined by the Board of Directors.
 
     Profit Sharing Plan.  In May 1996, the Board of Directors approved an
incentive-based profit sharing plan for employees of the Company, including all
executive officers. Under this plan, employees are paid cash bonuses on a
quarterly basis based upon the attainment of certain specified corporate goals
determined by the Board of Directors.
 
LIMITATION OF LIABILITY AND INDEMNIFICATION
 
     As permitted by the Delaware General Corporation Law (the "Delaware Law"),
the Company's Certificate of Incorporation provides that no director of the
Company will be personally liable to the Company or its stockholders for
monetary damages for breach of fiduciary duty as a director, except (i) for any
breach of the directors' duty of loyalty to the Company or its stockholders,
(ii) for acts or omissions not in good faith or involving intentional misconduct
or a knowing violation of law,
 
                                       50
<PAGE>   53
 
(iii) unlawful payments of dividends or unlawful stock repurchases or
redemptions, or (iv) for any transaction from which the director derives any
improper personal benefit. In addition, the Company's Bylaws provide that any
director or officer who was or is a party or is threatened to be made a party to
any action or proceeding by reason of his or her services to the Company will be
indemnified to the fullest extent permitted by the Delaware Law.
 
     The Company has entered into indemnification agreements with each of its
directors and executive officers pursuant to which the Company has indemnified
each of them against expenses and losses incurred for claims brought against
them by reason of their being a director or executive officer of the Company. In
addition, the Company maintains directors' and officers' liability insurance.
 
     There is no pending litigation or proceeding involving a director or
officer of the Company as to which indemnification is being sought, nor is the
Company aware of any pending or threatened litigation that may result in claims
for indemnification by any director or executive officer.

                 CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
LEVERAGED RECAPITALIZATION
 
     On November 30, 1995, the Company effected the Leveraged Recapitalization.
The Leveraged Recapitalization and related transactions consisted of: (i) the
repurchase by the Company from Hitachi Metals of shares of Common Stock
representing all the outstanding capital stock of the Company for an aggregate
purchase price of $52.1 million in cash; (ii) the recapitalization of the
Company through the sale of 21,968,057 shares of Common Stock for an aggregate
purchase price of approximately $0.7 million, 5,900,000 shares of Series A
Preferred Stock for an aggregate purchase price of approximately $59.0 million
and $47.0 million of Subordinated Notes; and (iii) the grant of options to
purchase 11,451,865 shares of Common Stock under the Stock Plans to certain
officers and employees of the Company. The purchasers of the Company's
securities in the Leveraged Recapitalization included certain investment funds
affiliated with Summit Partners and certain other investment funds, the
Company's management and employees and Hitachi Metals. Messrs. Kortschak and
Garfinkel, directors of the Company, are a General Partner and an employee of
Summit Partners, respectively. The Leveraged Recapitalization was undertaken in
order to provide liquidity to Hitachi Metals with respect to a portion of its
ownership interest in the Company.
 
     The following table shows the aggregate number of shares of Common Stock,
Series A Preferred Stock and Subordinated Notes received by affiliates of the
Company in connection with the recapitalization of the Company and the amount of

     The Subordinated Notes initially bear an interest rate of 12.0%, subject to
an increase of 1.0% a year beginning January 1, 1999. Interest on the
Subordinated Notes accrues through the earlier of July 31, 1996 or the payment
in full of a senior bank term loan incurred in connection with the Leveraged
Recapitalization. Thereafter, the interest will be payable quarterly in arrears
on the first business day of each calendar quarter. The Company repaid the
senior bank term loan in full in March 1996 upon completion of the initial
public offering. The Subordinated Notes are due in three equal installments of
principal on December 1, 2003, 2004 and 2005. While the Subordinated Notes may
be prepaid in whole or in part at the election of the Company, the Company is
obligated to prepay the Subordinated Notes from the proceeds of certain
financings after December 31, 1997. The Company intends to prepay the
Subordinated Notes and redeem the Series A Preferred Stock in full upon
completion of the Offerings.
 
     The Leveraged Recapitalization constituted a leveraged transaction. As of
November 30, 1995 (immediately prior to the reorganization), the Company had
approximately $98.5 million of assets and approximately $122.7 million of
liabilities. Immediately following the reorganization, the Company had $110.9
million in assets, $132.1 million in liabilities (including a $60.0 million
senior bank term loan and $47.0 million of Subordinated Notes) plus $59.0
million of Series A Preferred Stock.
 
     In connection with the Leveraged Recapitalization, the Company entered into
an agreement with Hitachi Metals providing for the reimbursement of California
franchise taxes paid by Hitachi Metals America, an affiliate of Hitachi Metals,
for the benefit of the Company in respect of fiscal 1995 and the period between
April 1, 1995 through November 30, 1995. The Company also paid Y7.0 million
 
                                       52
<PAGE>   55
 
(equivalent to approximately $65,000 based on Y107.0 per dollar as of May 24,
1996) to Hitachi Metals in consideration of the assignment of certain Japanese
patent rights held by Hitachi Metals to the Company.
 
HITACHI METALS, LTD. AND AFFILIATES
 
     Prior to the Leveraged Recapitalization, HMT was a wholly owned subsidiary
of Hitachi Metals. As a corporate parent of HMT, Hitachi Metals and its
affiliates provided certain support services, such as research and development
assistance, technical support and the guarantee of certain Company obligations.
During fiscal 1994, 1995 and 1996, HMT paid $150,000, $202,000 and $514,000,
respectively, for research and development and technical support. The Company
terminated these agreements by the end of fiscal 1996. Hitachi Metals or
affiliates of Hitachi Metals provided bank guaranties, which were released upon
completion of the Leveraged Recapitalization, relating to an aggregate principal
amount of $117.5 million in debt.
 
     The Company has secured distribution and sales support services from
Hitachi Metals Trading and Hitachi Kizoku Shoji, affiliates of Hitachi Metals,
for sales into the Japanese market. During fiscal 1994, 1995 and 1996, sales of
the Company's products through Hitachi Metals Trading totalled $23,000, $12,000,
and $19,000, respectively. During fiscal 1994 and 1995, sales through Hitachi
Kizoku Shoji were $4.7 million and $1.5 million, respectively.
 
   
     The Company purchases various manufacturing materials from Hitachi Metals
and its affiliates. During fiscal 1994, 1995 and 1996, the Company purchased
$3.5 million, $3.0 million, and $8.8 million, respectively, of nickel-plated
polished substrates through Hitachi Metals Trading. During the same periods, the
Company purchased $1.5 million, $1.0 million, and $2.3 million, respectively, of
sputtering process targets and other parts from Hitachi Metals America, an
affiliate of Hitachi Metals.
    
 
     The Company believes that these transactions with Hitachi Metals and its
affiliates were in the best interests of the Company and were on terms no less
favorable to HMT than could be obtained from unaffiliated third parties.
Nevertheless, the Board of Directors has adopted a policy that all future
material transactions with affiliates will be on terms no less favorable to the
Company than those available from unaffiliated third parties and will be subject
to review and approval by a majority of the disinterested members of the Board
of Directors.

                              DESCRIPTION OF NOTES
 
     The Notes are to be issued under an indenture to be dated as of

     The Notes will be general unsecured obligations of the Company subordinate
in right of payment to certain other obligations of the Company as described

on the payment of dividends, the repurchase of securities of the Company or the
incurrence of Senior Indebtedness. The Indenture contains no covenants or other
provisions to afford protection to holders of Notes in the event of a highly
leveraged transaction or a change in control of the Company except to the
limited extent described under "-- Repurchase at Option of Holders Upon a
Designated Event" below.

CONVERSION
 
     The holders of Notes will be entitled at any time through the close of
business on the final maturity date of the Notes, subject to prior redemption or
repurchase, to convert any Notes or portions thereof (in denominations of $1,000
or integral multiples thereof) into Common Stock of the Company, at the
conversion price set forth on the cover page of this Prospectus, subject to
adjustment as described below. Except as described below, no adjustment will be
made on conversion of any Notes for interest accrued thereon or for dividends on
any Common Stock issued. If Notes are converted after a record date for the
payment of interest and prior to (but excluding) the next succeeding interest
payment date, such Notes, other than Notes called for redemption during such
period, when submitted for conversion by the holder, must be accompanied by
funds equal to the interest payable on such succeeding interest payment date on
the principal amount so converted. No such payment will be required if the
Company exercises its right to redeem such Notes on a redemption date that is an
interest payment date. The Company is not required to issue fractional shares of
Common Stock upon conversion of Notes and, in lieu thereof, will pay a cash
adjustment based upon the market price of the Common Stock on the last business
day prior to the date of conversion. In the case of Notes called for redemption,
conversion rights will expire at the close of business on the business day
preceding the date fixed for redemption, unless the Company defaults in payment
of the redemption price.
 
     The right of conversion attaching to any Note may be exercised by the
holder by delivering the Note at the specified office of a conversion agent,
accompanied by a duly signed and completed notice of conversion, together with
any funds that may be required as described in the preceding paragraph. The
conversion date shall be the date on which the Note, the duly signed and
completed notice of conversion and any funds that may be required as described
in the preceding paragraph shall have been so delivered. A holder delivering a
Note for conversion will not be required to pay any taxes or duties payable in
respect of the issue or delivery of Common Stock on conversion, but will be
required to pay any tax or duty which may be payable in respect of any transfer
involved in the issue or delivery of the Common Stock in a name other than the
holder of the Note. Certificates representing shares of Common Stock will not be
issued or delivered unless all taxes and duties, if any, payable by the holder
have been paid.
 
     The conversion price set forth on the cover page of this Prospectus is
subject to adjustment in certain events, including: (i) the issuance of Common
Stock as a dividend or distribution on Common Stock of the Company; (ii) certain
subdivisions and combinations of the Common Stock; (iii) the issuance to all
holders of Common Stock of certain rights or warrants to purchase Common Stock
at less than the current market price of the Common Stock; (iv) the dividend or
other distribution to all holders of Common Stock of shares of capital stock of
the Company (other than Common Stock) or evidence of indebtedness of the Company
or assets (including securities, but excluding those rights, warrants, dividends
and distributions referred to above or paid exclusively in cash); (v) dividends
or other distributions consisting exclusively of cash (excluding any cash
portion of distributions referred to in clause (iv)) to all holders of Common
Stock to the extent that such distributions, combined together with (A) all
other such all-cash distributions made within the preceding 12 months in respect
of which no adjustment has been made plus (B) any cash and the fair market value
of other consideration payable in respect of any tender offers by the Company or
any of its subsidiaries for Common Stock concluded within the preceding 12
months in respect of which no adjustment has been made, exceeds 10% of the
Company's market capitalization (being the product of the then current market
price of the Common Stock times the number of shares of Common Stock then
outstanding) on the record date for such distribution; (vi) the purchase of
Common Stock pursuant to a tender offer made by the Company or any of its
subsidiaries to the extent that the same involves an aggregate consideration
that, together with (X) any cash and the fair market value of any other
consideration payable in any other tender offer by the Company or any of its
subsidiaries for Common Stock expiring within the 12 months preceding such
tender offer in respect of which no adjustment has been made plus (Y) the
aggregate amount of any such all-cash distributions referred to in clause (v)
above to all
 
                                       57
<PAGE>   60
 
holders of Common Stock within the 12 months preceding the expiration of such
tender offer in respect of which no adjustments have been made, exceeds 10% of
the Company's market capitalization on the expiration of such tender offer; and
(vii) payment in respect of a tender offer or exchange offer by a person other
than the Company or any subsidiary of the Company in which, as of the closing of
the offer, the Board of Directors is not recommending rejection of the offer.
The adjustment referred to in clause (vii) above will only be made if the tender
offer or exchange offer is for an amount which increases that person's ownership
of Common Stock to more than 25% of the total shares of Common Stock
outstanding, and only if the cash and value of any other consideration included
in such payment per share of Common Stock exceeds the current market price per
share of Common Stock on the business day next succeeding the last date on which
tenders or exchanges may be made pursuant to such tender or exchange. The
adjustment referred to in clause (vii) above will not be made, however, if, as
of the closing of the offer, the offering documents with respect to such offer
disclose a plan or an intention to cause the Company to engage in a
consolidation or merger of the Company or a sale of all or substantially all of
the Company's assets.
 
     The Indenture will provide that if the Company implements a stockholders'
rights plan, such rights plan must provide that upon conversion of the Notes the
holders will receive, in addition to the Common Stock issuable upon such
conversion, such rights whether or not such rights have separated from the
Common Stock at the time of such conversion.
 
     In the case of (i) any reclassification or change of the Common Stock
(other than changes in par value or resulting from a subdivision or combination)
or (ii) a consolidation, merger, or combination involving the Company or (iii) a
sale or conveyance to another corporation of the property and assets of the
Company, in each case as a result of which holders of Common Stock shall be
entitled to receive stock, other securities, other property or assets (including
cash) with respect to or in exchange for such Common Stock, the holders of the
Notes then outstanding will be entitled thereafter to convert such Notes into
the kind and amount of shares of stock, other securities or other property or
assets which they would have owned or been entitled to receive upon such
reclassification, change, consolidation, merger, combination, sale or conveyance
had such Notes been converted into Common Stock immediately prior to such
reclassification, change, consolidation, merger, combination, sale or conveyance
(assuming, in a case in which the Company's stockholders may exercise rights of
election, that a holder of Notes would not have exercised any rights of election
as to the stock, other securities or other property or assets receivable in
connection therewith and received per share the kind and amount received per
share by a plurality of nonelecting shares).
 
     In the event of a taxable distribution to holders of Common Stock (or other
transaction) which results in any adjustment of the conversion price, the
holders of Notes may, in certain circumstances, be deemed to have received a
distribution subject to United States income tax as a dividend; in certain other
circumstances, the absence of such an adjustment may result in a taxable
dividend to the holders of Common Stock. See "Certain Federal Income Tax
Considerations."
 
     The Company from time to time may to the extent permitted by law, reduce
the conversion price of the Notes by any amount for any period of at least 20
days, in which case the Company shall give at least 15 days' notice of such
decrease, if the Board of Directors has made a determination that such decrease
would be in the best interests of the Company, which determination shall be
conclusive. The Company may at its option, make such reductions in the
conversion price, in addition to those set forth above, as the Board of
Directors deems advisable to avoid or diminish any income tax to holders of
Common Stock resulting from any dividend or distribution of stock (or rights to
acquire stock) or from any event treated as such for income tax purposes. See
"Certain Federal Income Tax Considerations."
 
     No adjustment in the conversion price will be required unless such
adjustment would require a change of at least 1% in the conversion price then in
effect, provided that any adjustment that would otherwise be required to be made
shall be carried forward and taken into account in any subsequent adjustment.
Except as stated above, the conversion price will not be adjusted for the
issuance of
 
                                       58
<PAGE>   61
 
Common Stock or any securities convertible into or exchangeable for Common Stock
or carrying the right to purchase any of the foregoing.
 
OPTIONAL REDEMPTION BY THE COMPANY
 
     The Notes are not redeemable at the option of the Company prior to
            , 1998. At any time on or after that date the Notes may be redeemed
at the Company's option on at least 20 but not more than 60 days' notice, as a
whole or, from time to time in part, at the following prices (expressed in
percentages of the principal amount), together with accrued interest to, but
excluding, the date fixed for redemption; provided, however, that the Company
may not redeem the Notes prior to             , 1999 unless the closing price of
the Common Stock on the principal stock exchange or market on which the Common
Stock is then quoted or admitted to trading equals or exceeds 150% of the
conversion price for at least 20 trading days within a period of 30 consecutive
trading days ending on the fifth trading day prior to the date the notice of
redemption is first mailed to the holders of the Notes, provided, further that
if a redemption date is an interest payment date, the semi-annual payment of
interest becoming due on such date shall be payable to the holder of record as
of the relevant record date.
 
     If redeemed during the 12-month period beginning                     :

and 100% at             , 2003.
 
     If fewer than all the Notes are to be redeemed, the Trustee will select the
Notes to be redeemed in principal amounts of $1,000 or multiples thereof by lot
or, in its sole discretion, on a pro rata basis. If any Note is to be redeemed
in part only, a new Note or Notes in principal amount equal to the unredeemed
principal portion thereof will be issued. If a portion of a holder's Notes is
selected for partial redemption and such holder converts a portion of such
Notes, such converted portion shall be deemed to be taken from the portion
selected for redemption.
 
     No sinking fund is provided for the Notes.
 
REPURCHASE AT OPTION OF HOLDERS UPON A DESIGNATED EVENT
 
     The Indenture provides that if a Designated Event (as defined) occurs, each
holder of Notes shall have the right, at the holder's option, to require the
Company to repurchase all of such holder's Notes, or any portion thereof that is
an integral multiple of $1,000, on the date (the "repurchase date") that is 40
calendar days after the date of the Company Notice (as defined below), for cash
at a price equal to 100% of the principal amount of the Notes, together with
accrued interest, if any, to (but excluding) the repurchase date (the
"repurchase price"), provided, however, that if a repurchase date is an interest
payment date, the semi-annual payment of interest becoming due on such date
shall be payable to the holder of record as of the relevant record date.
 
     Within 15 days after the occurrence of a Designated Event, the Company is
obligated to mail to all holders of record of the Notes a notice (the "Company
Notice") of the occurrence of such Designated Event and of the repurchase right
arising as a result thereof. The Company must deliver a copy of the Company
Notice to the Trustee and cause a copy or a summary of such notice to be
published in a newspaper of general circulation in The City of New York. To
exercise the repurchase right, a holder of such Notes must deliver, on or before
the 35th day after the Company Notice, written notice to the Company (or an
agent designated by the Company for such purpose) and the Trustee of the
holder's
 
                                       59
<PAGE>   62
 
exercise of such right, together with the Notes with respect to which the right
is being exercised, duly endorsed for transfer.
 
     "Designated Event" means a Change in Control (as defined) or a Termination
of Trading (as defined).
 
     "Change in Control" means an event or series of events as a result of which
(i) any "person" or "group" (as such terms are used in Sections 13(d) and 14(d)
of the Exchange Act) is or becomes the "beneficial owner" (as defined in Rules
13d-3 and 13d-5 under the Exchange Act) of shares representing more than 50% of
the combined voting power of the then outstanding securities entitled to vote
generally in elections of directors of the Company ("Voting Stock"); (ii) the
stockholders of the Company approve any plan or proposal for the liquidation,
dissolution or winding up of the Company, (iii) the Company consolidates with or
merges into any other corporation, or conveys, transfers or leases all or
substantially all of its assets to any person, or any other corporation merges
into the Company, and in the case of any such transaction, the outstanding
Common Stock of the Company is changed or exchanged into or for other assets or
securities as a result, unless the stockholders of the Company immediately
before such transaction own, directly or indirectly immediately following such
transaction, at least 51% of the combined voting power of the outstanding voting
securities of the corporation resulting from such transaction in substantially
the same proportion as their ownership of the Voting Stock immediately before
such transaction; or (iv) the Continuing Directors (as defined below) do not
constitute a majority of the Board of Directors of the Company (or, if
applicable, a successor corporation to the Company); provided that a Change in
Control shall not be deemed to have occurred if either (x) the last sale price
of the Common Stock for any five trading days during the ten trading days
immediately preceding the Change in Control is at least equal to 105% of the
conversion price in effect on such day or (y) in the case of a merger or
consolidation, at least 90% of the consideration (excluding cash payments for
fractional shares) in such merger or consolidation constituting the Change in
Control consists of common stock traded on a United States national securities
exchange or quoted on the Nasdaq National Market (or which will be so traded or
quoted when issued or exchanged in connection with such Change in Control) and
as a result of such transaction or transactions such Notes become convertible
solely into such common stock.
 
     "Continuing Director" means at any date a member of the Company's Board of
Directors (i) who was a member of such board at the time of issuance of the
Notes or (ii) who was nominated or elected by at least a majority of the
directors who were Continuing Directors at the time of such nomination or
election or whose election to the Company's Board of Directors was recommended
or endorsed by at least a majority of the directors who were Continuing
Directors at the time of such nomination or election. (Under this definition, if
the current Board of Directors of the Company were to approve a new director or
directors and then resign, no Change in Control would occur even though the
current Board of Directors would thereafter cease to be in office.)
 
     A "Termination of Trading" shall have occurred if the Common Stock (or
other common stock into which the Notes are then convertible) is neither listed
for trading on a United States national securities exchange nor approved for
trading on an established automated over-the-counter trading market in the
United States.
 
     No quantitative or other established meaning has been given to the phrase
"all or substantially all" (which appears in the definition of Change in
Control) by courts which have interpreted this phrase in various contexts. In
interpreting this phrase, courts, among other things, make a subjective
determination as to the portion of assets conveyed, considering such factors as
the value of assets conveyed, the proportion of an entity's income derived from
the assets conveyed and the significance of those assets to the ongoing business
of the entity. To the extent the meaning of such phrase is uncertain,
uncertainty will exist as to whether or not a Change in Control may have
occurred (and, accordingly, as to whether or not the holders of Notes will have
the right to require the Company to repurchase their Notes).
 
                                       60
<PAGE>   63
 
     The foregoing provisions would not necessarily afford holders of the Notes
protection in the event of a highly leveraged transaction, a change in control
of the Company or other transactions involving the Company that may adversely
affect holders.
 
     No Notes may be repurchased at the option of holders upon a Designated
Event if there has occurred and is continuing an Event of Default described
under "-- Events of Default and Remedies" below (other than a default in the
payment of the repurchase price with respect to such Notes on the repurchase
date). If a Designated Event were to occur, there can be no assurance that the
Company would have sufficient financial resources, or would be able to arrange
financing, to pay the repurchase price for all Notes tendered by holders
thereof. In addition, the Company's credit agreement with respect to its senior
bank revolving credit facility prohibits the Company from repurchasing any Notes
and also identifies certain events that would constitute Designated Events, as
well as certain other change in control events with respect to the Company or
certain of its subsidiaries, which would constitute an event of default under
such credit agreement. Any future credit agreements or other agreements relating
to other indebtedness (including other Senior Indebtedness) to which the Company
becomes a party may contain similar restrictions and provisions. In the event a
Designated Event occurs at a time when the Company is prohibited from
repurchasing Notes, the Company could seek the consent of its lenders to the
repurchase of the Notes or could attempt to refinance the borrowings that
contain such prohibition. If the Company does not obtain such a consent or repay
such borrowings, the Company would remain prohibited from repurchasing Notes.
Any failure by the Company to repurchase the Notes when required following a
Designated Event would result in an Event of Default under the Indenture whether
or not such repurchase is permitted by the subordination provisions of the
Indenture. Any such default may, in turn, cause a default under Senior
Indebtedness of the Company. Moreover, the occurrence of a Designated Event may
cause an event of default under Senior Indebtedness of the Company. As a result,
in each case, any repurchase of the Notes would, absent a waiver, be prohibited
under the subordination provisions of the Indenture until the Senior
Indebtedness is paid in full. See "-- Subordination" below and "Risk
Factors -- Subordination and Absence of Financial Covenants."
 
     Certain leveraged transactions sponsored by the Company's management or an
affiliate of the Company could constitute a Change in Control that would give
rise to the repurchase right. The Indenture does not provide the Company's Board
of Directors with the right to limit or waive the repurchase right in the event
of any such leveraged transaction. Conversely, the Company could, in the future,
enter into certain transactions, including certain recapitalizations of the
Company, that would not constitute a Change in Control but that would increase
the amount of Senior Indebtedness (or other indebtedness) outstanding at such
time. There are no restrictions in the Indenture or the Notes on the creation of
additional Senior Indebtedness (or any other indebtedness) of the Company or any
of its subsidiaries and the incurrence of significant amounts of additional
indebtedness could have an adverse impact on the Company's ability to service
its debt, including the Notes. The Notes are subordinate in right of payment to
all existing and future Senior Indebtedness as described under
"-- Subordination" below.
 
     The right to require the Company to repurchase Notes as a result of a
Designated Event could have the effect of delaying, deferring or preventing a
Change of Control or other attempts to acquire control of the Company unless
arrangements have been made to enable the Company to repurchase all of the Notes
at the repurchase date. Consequently, the right may render more difficult or
discourage a merger, consolidation or tender offer (even if such transaction is
supported by the Company's Board of Directors or is favorable to the
stockholders), the assumption of control by a holder of a large block of the
Company's shares and the removal of incumbent management.
 
     No modification of the Indenture regarding the provisions on repurchase at
the option of any holder of a Note is permissible without the consent of the
holder of the Note so affected.
 
     Rule 13e-4 under the Exchange Act requires, among other things, the
dissemination of certain information to security holders in the event of an
issuer tender offer and may apply in the event that
 
                                       61
<PAGE>   64
 
the repurchase option becomes available to holders of the Notes. The Company
will comply with this rule to the extent applicable at that time.
 
SUBORDINATION
 
   
     The indebtedness evidenced by the Notes is, to the extent provided in the
Indenture, subordinate to the prior payment in full of all Senior Indebtedness
(as defined). Upon any distribution of assets of the Company upon any
dissolution, winding up, liquidation or reorganization of the Company, the
payment of the principal of, or premium, if any, and interest on the Notes is to
be subordinate to the extent provided in the Indenture in right of payment to
the prior payment in full of all Senior Indebtedness. Moreover, in the event of
any acceleration of the Notes because of an Event of Default, the holders of any
Senior Indebtedness then outstanding would be entitled to payment in full of all
obligations in respect of such Senior Indebtedness before the holders of the
Notes are entitled to receive any payment or distribution in respect thereof.
    
 
   
     The Company may not make any payment upon or in respect of the Notes if (i)
a default in the payment of principal of, premium, if any, interest, or other
payment due on Designated Senior Indebtedness (as defined below) occurs and is
continuing beyond any applicable period of grace or (ii) any other default
occurs and is continuing with respect to Designated Senior Indebtedness that
permits holders of the Designated Senior Indebtedness as to which such default
related to accelerate its maturity and the Trustee and the Company receive a
notice of such default (a "Payment Blockage Notice") from holders of at least $5
million in outstanding principal amount of Designated Senior Indebtedness.
Payments on the Notes shall be resumed (a) in case of payment default, on the
date on which such default is cured or waived and (b) in case of a nonpayment
default, on the earlier of the date on which such nonpayment default is cured or
waived or 179 days after the date on which the applicable Payment Blockage
Notice is received unless maturity of the Designated Senior Indebtedness has
been accelerated. No new period of payment blockage may be commenced pursuant to
a Payment Blockage Notice unless (i) 365 days have elapsed since the
effectiveness of the immediately prior Payment Blockage Notice and (ii) all
scheduled payments of principal, premium, if any, and interest on the Notes that
have become due have been paid in full in cash or the Trustee or the Noteholders
shall not have instituted proceedings to enforce the Noteholders' right to
receive such payments. No default (whether or not such default is on the same
issue of Designated Senior Indebtedness) that existed or was continuing on the
date of delivery of any Payment Blockage Notice shall be, or be made, the basis
for a subsequent Payment Blockage Notice. The payment of cash, property or
securities (other than Common Stock and other securities that are junior to the
Senior Indebtedness) upon conversion of a Note will constitute payment on a Note
and therefore will be subject to the subordination provisions of the Indenture.
    
 
     The term "Senior Indebtedness" means the principal of, premium, if any,
interest on (including any interest accruing after the filing of a petition by
or against the Company under any bankruptcy law, whether or not allowed as a
claim after such filing in any proceeding under such bankruptcy law), and any
other payment due pursuant to, any of the following, whether outstanding on the
date of the Indenture or thereafter incurred or created: (a) all indebtedness of
the Company for money borrowed or evidenced by notes, debentures, bonds or other
debt securities (including, but not limited to, those which are convertible or
exchangeable for securities of the Company); (b) all indebtedness of the Company
due and owing with respect to letters of credit (including, but not limited to,
reimbursement obligations with respect thereto); (c) all indebtedness or other
obligations of the Company due and owing with respect to interest rate and
currency swap agreements, cap, floor and collar agreements, currency spot and
forward contracts and other similar agreements and arrangements; (d) all
indebtedness consisting of commitment or standby fees due and payable to lending
institutions with respect to credit facilities or letters of credit available to
the Company; (e) all obligations of the Company under leases required or
permitted to be capitalized under generally accepted accounting principles; (f)
all indebtedness or obligations of others of the kinds described in any of the
preceding clauses (a), (b), (c), (d) or (e) assumed by or guaranteed in any
manner by the Company or in effect guaranteed (directly or indirectly) by the
Company through an agreement to purchase, contingent or otherwise,
 
                                       62
<PAGE>   65
 
and all obligations of the Company under any such guarantee or other
arrangements; and (g) all renewals, extensions, refundings, deferrals,
amendments or modifications of indebtedness or obligations of the kinds
described in any of the preceding clauses (a), (b), (c), (d), (e) or (f); unless
in the case of any particular indebtedness, obligation, renewal, extension,
refunding, amendment, modification or supplement, the instrument or other
document creating or evidencing the same or the assumption or guarantee of the
same expressly provides that such indebtedness, obligation, renewal, extension,
refunding, amendment, modification or supplement is subordinate to, or is not
superior to, or is pari passu with, the Notes; provided that Senior Indebtedness
shall not include (i) any indebtedness of any kind of the Company to any
subsidiary of the Company, a majority of the voting stock of which is owned,
directly or indirectly, by the Company or (ii) indebtedness for trade payables
or constituting the deferred purchase price of assets or services incurred in
the ordinary course of business.
 
     The term "Designated Senior Indebtedness" means any Senior Indebtedness if
the instrument creating or evidencing the same or the assumption or guarantee
thereof (or related agreements or documents to which the Company is a party)
expressly provides that such Indebtedness shall be "Designated Senior
Indebtedness" for purposes of the Indenture (provided that such instrument,
agreement or other document may place limitations and conditions on the right of
holders of such Senior Indebtedness to exercise the rights of Designated Senior
Indebtedness).
 
     In the event that, notwithstanding the foregoing, the Trustee or any holder
of Notes receives any payment or distribution of assets of the Company of any
kind in contravention of any of the terms of the Indenture, whether in cash,
property or securities, including, without limitation, by way of set-off or
otherwise, in respect of the Notes before all Senior Indebtedness is paid in
full, then such payment or distribution will be held by the recipient in trust
for the benefit of the holders of Senior Indebtedness of the Company, and will
be immediately paid over or delivered to the holders of Senior Indebtedness of
the Company or their representative or representatives to the extent necessary
to make payment in full of all Senior Indebtedness of the Company remaining
unpaid, after giving effect to any concurrent payment or distribution, or
provision therefor, to or for the holders of Senior Indebtedness of the Company.
 
   
     The Notes are obligations exclusively of the Company. Although the Company
does not currently have any operating subsidiaries, to the extent the Company
were to commence conducting certain operations or increase the level of existing
operations through subsidiaries, the cash flow and the consequent ability to
service debt, including the Notes, of the Company would be partially dependent
upon the earnings of any such subsidiaries and the distribution of those
earnings, or upon loans or other payments of funds by those subsidiaries, to the
Company. Such subsidiaries would be separate and distinct legal entities, and
would have no obligations, contingent or otherwise, to pay any amounts due
pursuant to the Notes or to make any funds available therefor, whether by
dividends, distributions, loans or other payments. In addition, the payment of
dividends or distributions and the making of loans and advances to the Company
by any such subsidiaries could be subject to statutory or contractual
restrictions, and could be contingent upon the earnings of those subsidiaries
and subject to various business considerations. Any right of the Company to
receive assets of subsidiaries upon their liquidation or reorganization (and the
consequent right of the holders of the Notes to participate in these assets)
would be effectively subordinated to the claims of that subsidiary's creditors
(including trade creditors), except to the extent that the Company is itself
recognized as a creditor of such subsidiary, in which case the claims of the
Company would still be subordinate to any security interests in the assets of
such subsidiary and any indebtedness of such subsidiary senior to that held by
the Company.
    
 
     As of March 31, 1996, the Company had outstanding approximately $8.5
million of indebtedness that would have constituted Senior Indebtedness. The
Indenture will not limit the amount of additional indebtedness, including Senior
Indebtedness, which the Company can create, incur, assume or guarantee, nor will
the Indenture limit the amount of indebtedness which any subsidiary of the
Company can create, incur, assume or guarantee.
 
                                       63

     No provision contained in the Indenture or the Notes will affect the
obligation of the Company, which is absolute and unconditional, to pay, when
due, principal of, premium, if any, interest on, the Notes. The subordination
provisions of the Indenture and the Notes will not prevent the occurrence of any
default or Event of Default or limit the rights of any holder of Notes, subject
to the preceding paragraphs to pursue any other rights or remedies with respect
to the Notes.
 
     As a result of these subordination provisions, in the event of the
liquidation, bankruptcy, reorganization, insolvency, receivership or similar
proceedings or an assignment for the benefit of the creditors of the Company or
a marshaling of assets or liabilities of the Company and its subsidiaries,
holders of the Notes may receive ratably less than other creditors.
 
EVENTS OF DEFAULT AND REMEDIES
 
     An Event of Default is defined in the Indenture as being: (i) a default in
payment of the principal of, or premium, if any, on the Notes (whether or not
such payment is prohibited by the subordination provisions of the Indenture);
(ii) default for 30 days in payment of any installment of interest on the Notes
(whether or not such payment is prohibited by the subordination provisions of
the Indenture); (iii) default by the Company for 60 days after notice given in
accordance with the Indenture in the observance or performance of any other
covenants in the Indenture; (iv) default in the payment of the repurchase price
in respect of any Note on the repurchase date therefor (whether or not such
payment is prohibited by the subordination provisions of the Indenture); (v)
failure to provide timely notice of a Designated Event; (vi) failure of the
Company or any Significant Subsidiary (as defined) to make any payment at
maturity, including any applicable grace period, in respect of Indebtedness
(which term as used in the Indenture means obligations (other than non-recourse
obligations) of, or guaranteed or assumed by, the Company or any Significant
Subsidiary for borrowed money or evidenced by bonds, notes or similar
instruments) in an amount in excess of $5,000,000 and continuance of such
failure for 30 days after notice given in accordance with the Indenture; (vii)
default by the Company or any Significant Subsidiary with respect to any
Indebtedness, which default results in the acceleration of indebtedness in an
amount in excess of $5,000,000 without such Indebtedness having been discharged
or such acceleration having been rescinded or annulled for 30 days after notice
given in accordance with the Indenture; or (viii) certain events involving
bankruptcy, insolvency or reorganization of the Company or any Significant
Subsidiary.
 
     The Indenture provides that the Trustee shall, within 90 days after the
occurrence of a default, give to the registered holders of the Notes notice of
all uncured defaults known to it, but the Trustee shall be protected in
withholding such notice if it in good faith determines that the withholding of
such notice is in the best interest of such registered holders, except in the
case of a default in the payment of the principal of, or premium, if any, or
interest on, any of the Notes when due or in the payment of any redemption or
repurchase obligation.
 
     The Indenture provides that if any Event of Default shall have occurred and
be continuing, the Trustee or the holders of not less than 25% in principal
amount of the Notes then outstanding may declare the principal of and premium,
if any, on the Notes to be due and payable immediately, but if the Company shall
cure all defaults (except the nonpayment of interest on, premium, if any, and
principal of any Notes which shall have become due by acceleration) and certain
other conditions are met, such declaration may be canceled and past defaults may
be waived by the holders of a majority in principal amount of Notes then
outstanding. If an Event of Default resulting from certain events of bankruptcy,
insolvency or reorganization were to occur, all unpaid principal of and accrued
interest on the outstanding Notes will become due and payable immediately
without any declaration or other act on the part of the Trustee or any holders
of Notes, subject to certain limitations.
 
     The Indenture provides that the holders of a majority in principal amount
of the outstanding Notes may direct the time, method and place of conducting any
proceeding for any remedy available to the Trustee or exercising any trust or
power conferred on the Trustee, subject to certain limitations specified in the
Indenture. Before proceeding to exercise any right or power under the Indenture
at
 
                                       64
<PAGE>   67
 
the direction of such holders, the Trustee shall be entitled to receive from
such holders reasonable security or indemnity against the costs, expenses and
liabilities which might be incurred by it in complying with any such direction.
The right of a holder to institute a proceeding with respect to the Indenture is
subject to certain conditions precedent, including the written notice by such
holder of an Event of Default and an offer to indemnify to the Trustee, along
with the written request by the holders of not less than 25% in principal amount
of the outstanding Notes that such a proceeding be instituted, but the holder
has an absolute right to institute suit for the enforcement of payment of the
principal of, and premium, if any, and interest on, such holder's Notes when due
and to enforce such holder's right to convert such Notes.
 
     The holders of not less than a majority in principal amount of the
outstanding Notes may on behalf of the holders of all Notes waive any past
defaults, except (i) a default in payment of the principal of, or premium, if
any, or interest on, any Note when due, (ii) a failure by the Company to convert
any Notes into Common Stock or (iii) in respect of certain provisions of the
Indenture which cannot be modified or amended without the consent of the holder
of each outstanding Note affected thereby.
 
     The Company is required to furnish to the Trustee annually a statement of
certain officers of the Company stating whether or not to the best of their
knowledge the Company is in default in the performance and observation of
certain terms of the Indenture and, if they have knowledge that the Company is
in default, specifying such default and its status.
 
LIMITATION ON MERGER, SALE OR CONSOLIDATION
 
     The Indenture provides that the Company may not, directly or indirectly,
consolidate with or merge with or into another person or sell, lease, convey or
transfer all or substantially all of its assets (computed on a consolidated
basis), whether in a single transaction or a series of related transactions, to
another person or group of affiliated persons, unless (i) either (a) the Company
is the surviving entity or (b) the resulting, surviving or transferee entity is
a corporation organized under the laws of the United States, any state thereof
or the District of Columbia and expressly assumes by written agreement all of
the obligations of the Company in connection with the Notes and the Indenture;
(ii) no default or Event of Default shall exist or shall occur immediately after
giving effect to such transaction; and (iii) certain other conditions are
satisfied.
 
     Upon any consolidation or merger or any transfer of all or substantially
all of the assets of the Company in accordance with the foregoing, the successor
corporation formed by such consolidation or into which the Company is merged or
to which such transfer is made, shall succeed to, and be substituted for, and
may exercise every right and power of, the Company under the Indenture with the
same effect as if such successor corporation had been named therein as the
Company, and the Company will be released from its obligations under the
Indenture and the Notes, except as to any obligations that arise from or as a
result of such transaction.
 
MODIFICATIONS OF THE INDENTURE
 
     The Indenture contains provisions permitting the Company and the Trustee,
with the consent of the holders of not less than a majority in principal amount
of the Notes at the time outstanding, to modify the Indenture or any
supplemental indenture or the rights of the holders of the Notes, except that no
such modification shall (i) extend the fixed maturity of any Note, reduce the
rate or extend the time or payment of interest thereon, reduce the principal
amount thereof or premium, if any, thereon, reduce any amount payable upon
redemption or repurchase thereof, impair or change in any respect adverse to the
holders of Notes the obligation of the Company to make repurchase of any Note
upon the happening of a Designated Event, impair or adversely affect the right
of a holder to institute suit for the payment thereof, change the currency in
which the Notes are payable, or impair or change in any respect adverse to the
holder of the Notes, the right to convert the Notes into Common Stock subject to
the terms set forth in the Indenture or modify the provisions of the Indenture
with respect to the subordination of the Notes in a manner adverse to the
holders of the Notes, without the consent
 
                                       65
<PAGE>   68
 
of the holder of each Note so affected, or (ii) reduce the aforesaid percentage
of Notes, without the consent of the holders of all of the Notes then
outstanding.
 
TAXATION OF NOTES
 
     See "Certain Federal Income Tax Considerations" for a discussion of certain
federal tax aspects which will apply to holders of Notes.
 
SATISFACTION AND DISCHARGE
 
     The Company may discharge its obligations under the Indenture while Notes
remain outstanding if (i) all outstanding Notes will become due and payable at
their scheduled maturity within one year or (ii) all outstanding Notes are
scheduled for redemption within one year, and, in either case, the Company has
deposited with the Trustee an amount sufficient to pay and discharge all
outstanding Notes on the date of their scheduled maturity or the scheduled date
of redemption.
 
GOVERNING LAW
 
     The Indenture and Notes will be governed by and construed in accordance
with the laws of the State of New York.
 
CONCERNING THE TRUSTEE
 
     State Street Bank and Trust Company, the Trustee under the Indenture, has
been appointed by the Company as the initial paying agent, conversion agent,
registrar and custodian with regard to the Notes. The Company may maintain
deposit accounts and conduct other banking transactions with the Trustee or its
affiliates in the ordinary course of business, and the Trustee and its
affiliates may from time to time in the future provide banking and other
services to the Company in the ordinary course of their business. The First
National Bank of Boston, an affiliate of the Trustee, is a co-agent and lender
under the Company's revolving credit facility.
 
     During the existence of an Event of Default, the Trustee will exercise such
rights and powers vested in it under the Indenture and use the same degree of
care and skill in its exercise as a prudent person would exercise under the
circumstances in the conduct of such person's own affairs. The Indenture
contains limitations of the rights of the Trustee, should it become a creditor
of the Company, to obtain payment of claims in certain cases or to realize on
certain property received by it in respect of any such claim or otherwise.
 
     The Indenture and the TIA will contain certain limitations on the rights of
the Trustee, should it become a creditor of the Company, to obtain payment of
claims in certain cases or to realize on certain property received in respect of
any such claim as security or otherwise. Subject to the TIA, the Trustee will be
permitted to engage in other transactions, provided, however, that if it
acquires any conflicting interest (as described in the TIA), it must eliminate
such conflict or resign.

                          DESCRIPTION OF CAPITAL STOCK
 
     The authorized capital stock of the Company consists of 100,000,000 shares
of Common Stock, $0.001 par value, and 15,000,000 shares of Preferred Stock,
$0.001 par value.
 
COMMON STOCK
 
     As of March 31, 1996, there were 38,719,178 shares of Common Stock
outstanding held of record by approximately 74 stockholders. The holders of
Common Stock are entitled to one vote per share on all matters to be voted on by
the stockholders. Subject to preferences that may be applicable to outstanding
shares of Preferred Stock, if any, the holders of Common Stock are entitled to
receive ratably such dividends as may be declared from time to time by the Board
of Directors out of funds legally available therefor. In the event of the
liquidation, dissolution or winding up of the Company, the holders of Common
Stock are entitled to share ratably in all assets remaining after payment of
liabilities, subject to prior liquidation rights of Preferred Stock, if any,
then outstanding. The Common Stock has no preemptive conversion rights or other
subscription rights. There are no redemption or sinking funds provisions
applicable to the Common Stock. All outstanding shares of Common Stock are fully
paid and non-assessable, and the shares of Common Stock to be outstanding upon
completion of the Offerings will be fully paid and non-assessable.
 
PREFERRED STOCK
 
     The Company currently has outstanding an aggregate of 5,900,000 shares of
Series A Preferred Stock. Commencing in 1998, the holders are entitled to
receive cumulative dividends at the annual rate of $1.00 per share. Dividends
for 1998 are payable on December 31, 1998 and are thereafter payable quarterly.
No dividends may be paid on the Common Stock of the Company while any shares of
Series A Preferred Stock are outstanding.
 
     Upon any liquidation, dissolution or winding up of the Company (a
"Liquidation Event"), the holders of the Series A Preferred Stock are entitled
to receive, prior to payment of any liquidation proceeds to the holders of any
other capital stock, including the Common Stock, an amount equal to $10.00 plus
all accrued and unpaid dividends per share of Series A Preferred Stock. A sale
of all or substantially all of the Company's assets or any consolidation or
merger of the Company in which holders of the Company's voting securities prior
to such merger or consolidation hold less than 50% of the voting power of the
surviving entity will also be regarded as a Liquidation Event and entitle the
holders of the Series A Preferred Stock to receive the liquidation preference.
 
     The Series A Preferred Stock may be redeemed by the Company at any time at
a redemption price of $10.00 per share plus all accrued and unpaid dividends
thereon. The Company must redeem all outstanding shares of Series A Preferred
Stock on January 1, 2006. In addition, after the Company's Subordinated Notes
have been retired, the Company is obligated to redeem shares of Series A
Preferred Stock from the proceeds of certain financings after December 31, 1997.
The Company intends to redeem the Series A Preferred Stock in full upon
completion of the Offerings.
 
     The consent of the holders of at least two-thirds of the then outstanding
shares of the Series A Preferred Stock is required in order: (i) to redeem or
purchase any shares of the Company's Common Stock, other than the repurchase of
shares from directors, officers, consultants or employees upon the termination
of their relationship with the Company or from stockholders pursuant to rights
of first refusal, (ii) to authorize or issue any equity security senior to, or
on a parity with, the Series A Preferred Stock with respect to liquidation
preferences, dividend preferences or redemption rights or (iii) to effect any
sale of all or substantially all of the Company's assets or any consolidation or
merger (other than a consolidation or merger in which the holders of the voting
securities of the Company retain at least 50% of the voting power of the
surviving entity) or any reclassification of shares or any recapitalization or
any dissolution, liquidation or winding up of the Company. The consent of the
holders of 95% of the Series A Preferred Stock is required for the amendment of
the Company's Certificate of Incorporation if such amendment changes the rights,
preferences or privileges of the
 
                                       67
<PAGE>   70
 
Series A Preferred Stock or would increase the designated number of shares of
Series A Preferred Stock. The Series A Preferred Stock does not have the right
to vote in the election of directors and has no other voting rights except as
described herein or required by law.
 
     The Board of Directors is authorized, without further action by the
Company's stockholders, to issue up to 9,100,000 shares of Preferred Stock in
one or more series and to fix the rights, preferences, privileges and
restrictions granted to or imposed upon such Preferred Stock, including dividend
rights, conversion rights, terms of redemption, liquidation preference, sinking
fund terms and the number of shares constituting any series or the designation
of such series, without any further vote or action by the stockholders, provided
that the rights, preferences and privileges of the Preferred Stock must be
subordinate to the Series A Preferred Stock as to dividend rights, rights upon
redemption and rights upon liquidation, except as the holders of at least 95% of
the Series A Preferred Stock may otherwise agree. The Board of Directors,
without stockholder approval, can issue Preferred Stock with voting and
conversion rights which could adversely affect the voting power of the holders
of Common Stock. The issuance of Preferred Stock may have the effect of
delaying, deferring or preventing a change in control of the Company. The
Company has no present plan to issue any additional shares of Preferred Stock.
 
WARRANTS
 
     In connection with the Leveraged Recapitalization, pursuant to a warrant
purchase agreement dated November 30, 1995, the Company issued to certain senior
lenders (the "Warrantholders") warrants to purchase an aggregate of 701,344
shares of Common Stock at a price of $0.0003 per share. The warrants terminate
on November 30, 2002. Upon any reorganization or reclassification, consolidation
or merger or any sale or other transfer of substantially all of its assets the
warrants may be repurchased by the Company with the consent of the
Warrantholder. In the event the Warrantholders do not consent to such
repurchase, the warrants must be exercised prior to the consummation of such
transaction and will be converted into the right to receive a comparable number
of securities or property of the surviving corporation. The warrants include a
net exercise provision, and the Warrantholders have the right to cause the
Company to repurchase the warrants and any shares issued upon exercise thereof
under certain circumstances. Upon payment of the outstanding balance of the
senior bank term loan in March 1996, the Company redeemed the warrants for
280,550 shares of Common Stock at the Warrantholders' cost ($0.02), leaving a
balance of 420,794 shares subject to the remaining warrants. In addition, the
Warrantholders have certain registration rights with respect to the shares of
Common Stock issuable upon exercise of such warrants.
 
REGISTRATION RIGHTS
 
     Pursuant to an agreement between the Company and the holders (or their
permitted transferees) of approximately 29,656,057 shares of Common Stock
("Holders"), the Holders are entitled to certain rights with respect to the
registration of such shares under the Securities Act of 1933, as amended (the
"Securities Act"). If the Company proposes to register its Common Stock, subject
to certain exceptions, under the Securities Act, the Holders are entitled to
notice of the registration and are entitled to include, at the Company's
expense, such shares therein, provided that the managing underwriters have the
right to limit the number of such shares included in the registration. The
Company has requested that the Holders waive their registration rights with
respect to the Offerings, and certain of the Holders may sell shares of Common
Stock pursuant to the Underwriters' over-allotment options in the Common Stock
Offering. In addition, certain of the Holders may require the Company at its
expense on no more than two occasions within six months to file a registration
statement under the Securities Act with respect to their shares of Common Stock.
Such rights may not be exercised until September 1996. Further, certain Holders
may require the Company at its expense to register their shares on Form S-3 when
such form becomes available to the Company, subject to certain conditions and
limitations. Such right expires in March 2001.
 
                                       68
<PAGE>   71
 
     The Warrantholders also have certain registration rights with respect to
the shares of Common Stock issuable upon exercise of the warrants pursuant to
the Warrant Purchase Agreement. If the Company proposes to register Common
Stock, the Warrantholders are entitled at the Company's expense, to include such
shares therein, provided that the maximum number of shares to be offered, as
determined by the managing underwriters, exceeds the number of shares that the
Company intends to offer. Certain of the Warrantholders may sell shares of
Common Stock pursuant to the Underwriters' over-allotment options in the Common
Stock Offering. Pursuant to the Warrant Purchase Agreement, the Company has
exercised its right to sell for its own account all of the Common Stock shares
offered hereby. In addition, the Warrantholders holding at least 25% of the
outstanding warrants may require the Company at its expense on one occasion to
file a registration statement under the Securities Act with respect to the
Common Stock issuable upon the exercise of the warrants. Such rights may not be
exercised until September 1996. The Company will also make efforts in good faith
to ensure the availability of sales pursuant Form S-3 and Rule 144.
 
DELAWARE ANTI-TAKEOVER LAW AND CERTAIN CHARTER PROVISIONS
 
     The Company is governed by the provisions of Section 203 of the Delaware
Law. In general, Section 203 prohibits a public Delaware corporation from
engaging in a "business combination" with an "interested stockholder" for a
period of three years after the date of the transaction in which the person
became an interested stockholder, unless the business combination is approved in
a prescribed manner. A "business combination" includes mergers, asset sales and
other transactions resulting in a financial benefit to the stockholder. An
"interested stockholder" is a person who, together with affiliates and
associates, owns (or within three years, did own) 15% or more of a corporation's
voting stock. The statute could have the effect of delaying, deferring or
preventing a change in control of the Company.
 
     The Company's Certificate of Incorporation and Bylaws also require that any
action required or permitted to be taken by stockholders of the Company must be
effected at a duly called annual or special meeting of the stockholders and may
not be effected by a consent in writing. In addition, special meetings of the
stockholders of the Company may be called only by the Board of Directors, the
Chairman of the Board, the Chief Executive Officer of the Company or by any
person or persons holding shares representing at least 20% of the outstanding
capital stock. The Company's Certificate of Incorporation also specifies that
the authorized number of directors may be changed only by resolution of the
Board of Directors. These provisions may have the effect of deterring hostile
takeovers or delaying changes in control or management of the Company.
 
TRANSFER AGENT AND REGISTRAR
 
     The transfer agent and registrar for the Company's Common Stock is The
First National Bank of Boston. Its telephone number is (617) 575-2000.
 
                   CERTAIN FEDERAL INCOME TAX CONSIDERATIONS
 
     The following is a general discussion of certain United States federal
income tax considerations relevant to holders of the Notes. This discussion is
based upon the Internal Revenue Code of 1986, as amended (the "Code"), Treasury
Regulations, Internal Revenue Service ("IRS") rulings and judicial decisions now
in effect all of which are subject to change (possibly with retroactive effect)
or different interpretations. This discussion does not purport to deal with all
aspects of federal income taxation that may be relevant to a particular
investor's decision to purchase the Notes, and it is not intended to be wholly
applicable to all categories of investors, some of which, such as dealers in
securities, banks, insurance companies, tax-exempt organizations and non-United
States persons, may be subject to special rules. In addition, this discussion is
limited to persons that purchase the Notes in the Note Offering and hold the
Notes as a "capital asset" within the meaning of Section 1221 of the Code.
 
                                       69
<PAGE>   72
 
     ALL PROSPECTIVE PURCHASERS OF THE NOTES ARE ADVISED TO CONSULT THEIR OWN
TAX ADVISORS REGARDING THE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES OF
THE PURCHASE, OWNERSHIP AND DISPOSITION OF THE NOTES AND THE COMMON STOCK.
 
INTEREST INCOME
 
     A holder of a Note will generally be required to report as income for
federal income tax purposes interest earned on the Note in accordance with the
holder's method of tax accounting. A holder of a Note using the accrual method
of accounting for tax purposes is required to include interest in ordinary
income as such interest accrues, while a cash basis holder must include interest
in income when payments are received (or made available for receipt).
 
CONVERSION OF NOTES INTO COMMON STOCK
 
     In general, no gain or loss will be recognized for federal income tax
purposes on a conversion of the Notes into shares of Common Stock. However, cash
paid in lieu of a fractional share of Common Stock will likely result in taxable
gain (or loss), which will be capital gain or loss, to the extent that the
amount of such cash exceeds (or is exceeded by) the portion of the adjusted
basis of the Note allocable to such fractional share. The adjusted basis of
shares of Common Stock received on conversion will equal the adjusted basis of
the Note converted, reduced by the portion of adjusted basis allocated to any
fractional share of Common Stock exchanged for cash. The holding period of an
investor in the Common Stock received on conversion will include the period
during which the converted Notes were held.
 
     The conversion price of the Notes is subject to adjustment under certain
circumstances. See "Description of Notes -- Conversion." Section 305 of the Code
and the Treasury Regulations issued thereunder may treat the holders of the
Notes as having received a constructive distribution, resulting in ordinary
income (subject to a possible dividends received deduction in the case of
corporate holders) to the extent of the Company's then current and/or
accumulated earnings and profits, if and to the extent that certain adjustments
in the conversion price that may occur in limited circumstances (particularly an
adjustment to reflect a taxable dividend to holders of Common Stock) increase
the proportionate interest of a holder of Notes in the fully diluted Common
Stock, whether or not such holder ever exercises its conversion privilege.
Moreover, if there is not a full adjustment to the conversion price of the Notes
to reflect a stock dividend or other event increasing the proportionate interest
of the holders of outstanding Common Stock in the assets or earnings and profits
of the Company, then such increase in the proportionate interest of the holders
of the Common Stock generally will be treated as a distribution to such holders,
taxable as ordinary income (subject to a possible dividends received deduction
in the case of corporate holders) to the extent of the Company's then current
and/or accumulated earnings.
 
MARKET DISCOUNT
 
     Investors acquiring Notes pursuant to this Prospectus should note that the
resale of those Notes may be adversely affected by the market discount
provisions of sections 1276 through 1278 of the Code. Under the market discount
rules, if a holder of a Note purchases it at market discount (i.e., at a price
below its stated redemption at maturity) in excess of a statutorily-defined de
minimis amount and thereafter recognizes gain upon a disposition or retirement
of the Note, then the lesser of the gain recognized or the portion of the market
discount that accrued on a ratable basis (or, if elected, on a constant interest
rate basis) generally will be treated as ordinary income at the time of the
disposition. Moreover, any market discount on a Note may be taxable to an
investor to the extent of appreciation at the time of certain otherwise
non-taxable transactions (e.g., gifts). Any accrued market discount not
previously taken into income prior to a conversion of a Note, however, should
carry over to the Common Stock received on conversion and be treated as ordinary
income upon a subsequent disposition of such Common Stock to the extent of any
gain recognized on such disposition. In
 
                                       70
<PAGE>   73
 
addition, absent an election to include market discount in income as it accrues,
a holder of a market discount debt instrument may be required to defer a portion
of any interest expense that otherwise may be deductible on any indebtedness
incurred or maintained to purchase or carry such debt instrument until the
holder disposes of the debt instrument in a taxable transaction.
 
SALE, EXCHANGE OR RETIREMENT OF NOTES
 
     Each holder of Notes generally will recognize gain or loss upon the sale,
exchange, redemption, repurchase, retirement or other disposition of those Notes
measured by the difference (if any) between (i) the amount of cash and the fair
market value of any property received (except to the extent that such cash or
other property is attributable to the payment of accrued interest not previously
included in income, which amount will be taxable as ordinary income) and (ii)
the holder's adjusted tax basis in those Notes (including any market discount
previously included in income by the holder). Each holder of Common Stock into
which the Notes are converted, in general, will recognize gain or loss upon the
sale, exchange, redemption, or other disposition of the Common Stock measured
under rules similar to those described in the preceding sentence for the Notes.
Special rules may apply to redemptions of Common Stock which may result in
different treatment. Any such gain or loss recognized on the sale, exchange,
redemption, repurchase, retirement or other disposition of a Note or share of
Common Stock should be capital gain or loss (except as discussed under
"-- Market Discount" above), and would be long-term capital gain or loss if the
Note or the Common Stock had been held for more than one year at the time of the
sale or exchange. An investor's initial basis in a Note will be the cash price
paid therefor.
 
BACK-UP WITHHOLDING
 
     A holder of Notes or Common Stock may be subject to "back-up withholding"
at a rate of 31% with respect to certain "reportable payments," including
interest payments, dividend payments and, under certain circumstances, principal
payments on the Notes. These back-up withholding rules apply if the holder,
among other things, (i) fails to furnish a social security number or other
taxpayer identification number ("TIN") certified under penalties of perjury
within a reasonable time after the request therefor, (ii) furnishes an incorrect
TIN, (iii) fails to report properly interest or dividends, or (iv) under certain
circumstances, fails to provide a certified statement, signed under penalties of
perjury, that the TIN furnished is the correct number and that holder is not
subject to back-up withholding. A holder who does not provide the Company with
its correct TIN also may be subject to penalties imposed by the IRS. Any amount
withheld from a payment to a holder under the back-up withholding rules is
creditable against the holder's federal income tax liability, provided the
required information is furnished to the IRS. Back-up withholding will not
apply, however, with respect to payments made to certain holders, including
corporations, tax-exempt organizations and certain foreign persons, provided
their exemption from back-up withholding is properly established.
 
     The Company will report to the holders of Notes and Common Stock and to the
IRS the amount of any "reportable payments" for each calendar year and the
amount of tax withheld, if any, with respect to such payments.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
     No prediction can be made as to the effect, if any, that market sales of
shares or the availability of shares for sale will have on the market price
prevailing from time to time. Nevertheless, sales of substantial amounts of
Common Stock of the Company in the public market after the lapse of the
restrictions described below could adversely affect the prevailing market price
and the ability of the Company to raise equity capital in the future at a time
and place which it deems appropriate.
 
   
     Upon completion of the Offerings, the Company will have 43,979,178 shares
of Common Stock outstanding, assuming no exercise of the Underwriters'
over-allotment options, no conversion of the Notes, no exercise of outstanding
options and no exercise of outstanding warrants after March 31, 1996. Of these
shares, 13,660,000 shares of Common Stock (including the 4,000,000 shares sold
in the Common Stock Offering) will be freely tradeable without restriction or
registration under the Securities Act, except for any shares purchased by
affiliates of the Company. 30,319,178 of the shares were sold by the Company in
reliance on exemptions from the registration requirements of the Securities Act
and are "restricted" shares within the meaning of Rule 144 adopted under the
Securities Act (the "Restricted Shares"), or were sold under written
compensation plans under Rule 701 adopted under the Securities Act. 30,121,057
of such Restricted Shares are subject to lockup agreements with the Underwriters
(the "Lockup Agreements") pursuant to which such shares may not be offered,
sold, or otherwise disposed of without the prior written consent of Robertson,
Stephens & Company LLC. Such Lockup Agreements expire four days after the
announcement by the Company of its operating results for the three months ending
September 30, 1996 as to 8,153,000 Restricted Shares. Of these 8,153,000
Restricted Shares, 3,922,314 will be available for immediate sale pursuant to
Rule 144 and Rule 701, 146,382 may be available for immediate sale pursuant to
Rule 144 and Rule 701 based upon achievement of certain performance goals, and
the remaining 4,084,304 will be subject to rights of repurchase in favor of the
Company that expire at various dates through December 2004 pursuant to monthly
vesting, or earlier upon the achievement of certain performance goals, and may
not be resold until such rights expire. Such Lockup Agreements expire on March
13, 1997 as to the remaining 21,968,057 Restricted Shares. The holders of such
21,968,057 shares will be eligible to sell such shares pursuant to Rule 144 upon
the expiration of a two-year holding period from the date such shares were
acquired (in most cases November 30, 1995), subject to certain volume
limitations under Rule 144.
    
 
     In general, under Rule 144 as currently in effect, a person (or persons
whose shares are aggregated), including persons who may be deemed "affiliates,"
who has beneficially owned Restricted Shares for at least two years (as computed
under Rule 144) is entitled to sell in "broker's transactions" or to market
makers, within any three-month period commencing 90 days after the date of
Prospectus, a number of shares that does not exceed greater of (i) one percent
of the then outstanding shares of the Company's Common Stock (approximately
439,792 shares immediately after completion of the Offerings) or (ii) the
average weekly trading volume in the Common Stock during the four calendar weeks
preceding the filing of a Form 144 with respect to such sale. Sales under Rule
144 are also subject to certain requirements as to manner of sale, the filing of
a notice, and the availability of public information concerning the Company. In
addition, a person who is not deemed to have been an affiliate of the Company at
any time during the three-month period preceding a sale and who has beneficially
owned the Restricted Shares proposed to be sold for at least three years
(including the continuous holding period of any prior owner except an
affiliate), would be entitled to sell such shares under Rule 144(k) without
regard to the volume limitations and certain other requirements described above.
Restricted Shares and options to purchase Common Stock sold by the Company to,
among others, its employees, officers and directors pursuant to written
compensation plans or contracts and in reliance on Rule 701 under the Act, may
be resold in reliance on Rule 144 by such persons who are not affiliates subject
only to the provisions of Rule 144 regarding manner of sale, and by such persons
who are affiliates without complying with the Rule's holding period
requirements.
 
   
     The Company has filed a registration statement under the Securities Act to
register 7,312,029 shares of Common Stock reserved for issuance under the 1995
Plan, the Incentive Plan, the Directors' Plan and the Purchase Plan, thus
permitting the sale of such shares by non-affiliates in the public

market without restriction under the Securities Act. Such registration statement
became effective immediately upon filing. The shares to be registered include
shares issuable upon exercise of options to purchase 3,917,723 shares that were
issued and outstanding at March 31, 1996. As of May 31, 1996, options to
purchase approximately 459,883 of such shares were exercisable and immediately
saleable. The remainder of these shares will become exercisable and saleable at
various dates through December 1999 pursuant to monthly vesting.
    
 
     The Company has also agreed not to offer, sell, contract to sell or
otherwise dispose of any shares of Common Stock or any securities convertible
into or exercisable or exchangeable for Common Stock for a period ending four
days after the announcement by the Company of its operating results for the
three months ending September 30, 1996, subject to certain exceptions.

     The Representatives have advised the Company that the Underwriters propose
to offer the shares of Common Stock and the Notes to the public at the public
offering price set forth on the cover page of this Prospectus and to certain
dealers at such price less a concession of not in excess of $   per share, of
which $   may be reallowed to other dealers and of not more than      % of the
principal amount of the Notes. After the public offering, the public offering
price, concession and reallowance to dealers may be reduced by the
Representatives. No such reduction shall change the amount of proceeds to be
received by the Company as set forth on the cover page of this Prospectus.
 
     The Selling Stockholders have granted to the Underwriters options,
exercisable during the 30-day period after the date of this Prospectus, to
purchase up to 600,000 shares of Common Stock at the same price per share as the
Company receives for the 4,000,000 shares of Common Stock that the Underwriters
have agreed to purchase from the Company. The Company also has granted to the
Underwriters an option, exercisable during the 30-day period after the date of
this Prospectus, to purchase up to $22.5 million principal amount of Notes, at
the same price per Note as the Company receives for the first $150.0 million
principal amount of Notes that the Underwriters have agreed to purchase from the
Company. To the extent that the Underwriters exercise such options, each of the
Underwriters will have a firm commitment to purchase approximately the same
percentage of such additional Common Stock and Notes as the Common Stock and
principal amount of Notes to be purchased by it shown in the above table
represents as a percentage of 4,000,000 shares and the $150.0 million principal
amount of Notes offered hereby, respectively. If purchased, such additional
shares and Notes will be sold by the Underwriters on the same terms as those on
which the 4,000,000 shares of Common Stock and the $150.0 million principal
amount of Notes are being sold.
 
     The respective Underwriting Agreements contain covenants of indemnity among
the Underwriters and the Company against certain civil liabilities, including
liabilities under the Securities Act.
 
     Pursuant to the terms of Lockup Agreements, certain officers and directors
holding an aggregate of 7,688,000 shares of Common Stock and certain
stockholders holding an aggregate of 21,968,057 shares of Common Stock have
agreed with the Representatives that, for a period ending four days after the
announcement by the Company of its operating results for the three months ending
September 30, 1996 and March 13, 1997, respectively, they will not offer to
sell, contract to sell or otherwise sell,

dispose of or grant any rights with respect to any shares of Common Stock, any
options or warrants to purchase shares of Common Stock or any securities
convertible into or exchangeable for shares of Common Stock now owned or
hereinafter acquired directly by such holders or with respect to which they have
the power of disposition, otherwise than with the prior written consent of
Robertson, Stephens & Company LLC. Robertson, Stephens & Company LLC may, in its
sole discretion and at any time without notice, release all or any portion of
the securities subject to Lockup Agreements. The Company has also agreed not to
offer, sell, contract to sell or otherwise dispose of any shares of Common Stock
or any securities convertible into or exercisable or exchangeable for Common
Stock, or any options or warrants to purchase Common Stock other than shares or
options issued under the Company's stock and option plans and stock issued upon
the exercise of presently outstanding warrants for a period ending four days
after the announcement by the Company of its operating results for the three
months ending September 30, 1996, except with the prior written consent of
Robertson, Stephens & Company LLC.
 
     The Representatives have advised the Company that the Underwriters do not
intend to confirm any sales to accounts over which they exercise discretionary
authority.
 
     The offering price of the Common Stock will be determined by negotiations
among the Company and the Representatives of the Underwriters, based largely
upon the market price for the Common Stock as reported on the Nasdaq National
Market.
 
     The rules of the Commission generally prohibit the Underwriters and other
members of the selling group from making a market in the Company's Common Stock
during the period immediately preceding the commencement of sales in the
offering. The Commission has, however, adopted an exemption from these rules
that permits passive market making under certain conditions. These rules permit
an Underwriter or other member of the selling group to continue to make a market
in the Company's Common Stock subject to the conditions, among others, that its
bid not exceed the highest bid by a market maker not connected with the offering
and that its net purchases on any one trading day not exceed prescribed limits.
Pursuant to these exemptions, certain Underwriters and other members of the
selling group intend to engage in passive market making in the Company's Common
Stock during such period.
 
     Prior to the Note Offering, there has been no trading market for the Notes.
The Company expects that the Notes will trade on the over-the-counter market.
However, there can be no assurance that an active trading market for the Notes
will develop or, if such market develops, as to the liquidity or sustainability
of such market. The Underwriters named on the cover page of this Prospectus have
advised the Company that they currently intend to make a market in the Notes,
but they are not obligated to do so and may discontinue such market making at
any time. There can be no assurance that an active market for the Notes will
develop and continue upon completion of the Note Offering or that the market
price of the Notes will not decline. Various factors such as changes in
prevailing interest rates or changes in perceptions of the Company's
creditworthiness could cause the market price of the Notes to fluctuate
significantly. The trading price of the Notes could also be significantly
affected by the market price of the Common Stock, which could be subject to wide
fluctuations in response to a variety of factors, including quarterly variations
in operating results, announcements of technological innovations or new products
by the Company, its customers or its competitors, developments in patents or
other intellectual property rights, general conditions in the computer or disk
drive industry and general economic and market conditions. Factors creating
volatility in the trading price of the Common Stock could have a significant
impact on the trading price of the Notes.

                                 LEGAL MATTERS
 
   
     The validity of the Common Stock and the Notes offered hereby will be
passed upon for the Company by Cooley Godward Castro Huddleson & Tatum, Palo
Alto, California ("Cooley Godward"). Certain legal matters related to the
Offerings will be passed upon for the Underwriters by Wilson Sonsini Goodrich &
Rosati, Professional Corporation, Palo Alto, California. As of the date of this
Prospectus, Cooley Godward beneficially owns 93,000 shares of the Common Stock,
subject to the Company's right of repurchase. In addition, James C. Kitch, a
partner of Cooley Godward, is the Secretary of the Company.
    
 
                                    EXPERTS
 
     The consolidated financial statements of the Company as of March 31, 1995
and 1996 and for each of the three years in the period ended March 31, 1996
included in this Prospectus and the related financial statement schedules
included elsewhere in the Registration Statement of which this Prospectus is a
part, have been included herein in reliance on the reports of Coopers & Lybrand
L.L.P., independent accountants, given on the authority of those firms as
experts in accounting and auditing.
 
                             ADDITIONAL INFORMATION
 
     A Registration Statement on Form S-1, including amendments thereto,
relating to the Common Stock and Notes offered hereby has been filed by the
Company with the Securities and Exchange Commission. This Prospectus does not
contain all of the information set forth in the Registration Statement and the
exhibits and schedules thereto. For further information with respect to the
Company and the Common Stock and Notes offered hereby, reference is made to such
Registration Statement and the exhibits and schedules filed as a part thereof. A
copy of the Registration Statement, including exhibits and schedules thereto,
may be inspected by anyone without charge at the public reference facilities
maintained by the Commission at 450 Fifth Street, N.W., Judiciary Plaza,
Washington, D.C. 20549, and copies of all or any part thereof may be obtained
from the Commission upon the payment of certain fees prescribed by the
Commission.
 
     In December 1995, the Company decided to retain Coopers & Lybrand L.L.P. as
the independent accountants for the Company and dismissed Ernst & Young LLP, the
Company's former accountants. The decision to change independent accountants was
approved by the Company's Board of Directors and was made in connection with the
Leveraged Recapitalization. There were no disagreements with the former
accountants regarding any matters with respect to accounting principles or
practices, financial statement disclosure or auditing scope or procedure through
December 1995, or with respect to the Company's financial statements for the
fiscal years ended March 31, 1994 and 1995. The former accountants' reports for
the fiscal years ended March 31, 1994 and 1995 are not a part of the financial
statements of the Company included in this Prospectus and the related financial
statement schedules included elsewhere in the Registration Statement. Such
reports did not contain an adverse opinion or disclaimer of an opinion or
qualifications as to uncertainty, audit scope or accounting principles. Prior to
retaining Coopers & Lybrand L.L.P., the Company had not consulted with Coopers &
Lybrand L.L.P. regarding accounting principles. However, Hitachi Metals and
certain stockholders of HMT had consulted Coopers & Lybrand L.L.P. for the
limited purpose of determining appropriate accounting treatment of the Leveraged
Recapitalization.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To The Board of Directors and Stockholders
HMT Technology Corporation
 
     We have audited the accompanying consolidated balance sheets of HMT
Technology Corporation and its subsidiary as of March 31, 1995 and 1996, and the
related consolidated statements of operations, stockholders' equity (deficit)
and cash flows for each of the three years in the period ended March 31, 1996.
These financial statements are the responsibility of the Company's management.
Our responsibility is to express an opinion on these financial statements based
on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of HMT
Technology Corporation and its subsidiary at March 31, 1995 and 1996, and the
results of their operations and their cash flows for each of the three years in
the period ended March 31, 1996, in conformity with generally accepted
accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Basis of Presentation
 
     HMT Technology Corporation (the "Company"), operates in a single industry
segment, and designs, manufactures and markets thin film magnetic disks for use
in computer hard drives. The Company was incorporated in Delaware on December
28, 1988.
 
  Basis of Consolidation
 
     The consolidated financial statements include the accounts of the Company
and its wholly-owned subsidiary, HMT Foreign Sales Corporation (incorporated on
February 14, 1996). All significant intercompany accounts and transactions have
been eliminated in consolidation.
 
  Fiscal Year
 
     The Company uses a 52-week fiscal year ending on March 31 and thirteen- to
fourteen-week quarters that end on the Sunday closest to the calendar quarter
end.
 
  Recapitalization
 
     On November 30, 1995, the Company effected a leveraged recapitalization
(the "Leveraged Recapitalization") pursuant to which the Company repurchased
from Hitachi Metals, Ltd. ("Hitachi Metals"), then the sole stockholder of the
Company, all of the outstanding shares of Common Stock of the Company, and
certain investment funds, members of management and Hitachi Metals purchased
newly issued Common Stock, Mandatorily Redeemable Series A Preferred Stock
("Series A Preferred Stock") and subordinated promissory notes ("Subordinated
Notes") of the Company. As of November 30, 1995 (immediately prior to the
Leveraged Recapitalization), the Company had approximately $98.5 million in
assets (unaudited) and approximately $122.7 million in liabilities (unaudited).
Immediately following the Leveraged Recapitalization, the Company had $110.9
million in assets (unaudited), and $132.1 million in liabilities (unaudited)
(including $60.0 million of senior bank term loan and $47.0 million of
Subordinated Notes to stockholders) and $59.0 million of Series A Preferred
Stock.
 
     The Leveraged Recapitalization has been accounted for as a
recapitalization, and accordingly, no change in the accounting basis of the
Company's assets has been made in the accompanying financial statements. The
amount of cash paid and securities issued to the stockholders of the Company
exceeded the Company's net assets on the date of the transaction and has been
recorded in the equity section as distributions in excess of net book value.
 
  Stock Split
 
     The Company's Board of Directors effected a 31-for-1 stock split on March
13, 1996. All shares and per share data in the accompanying financial statements
have been retroactively restated to reflect the stock split.
 
  Cash and Cash Equivalents
 
     The Company considers all highly liquid investments with an original
maturity of three months or less from the date of purchase and money market
funds to be cash equivalents. The Company maintains deposits with several
financial institutions in the United States and invests its excess cash in
short-term, interest bearing, investment grade securities. Deposits in banks may
exceed the amount of
 
                                       F-7

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
insurance provided on such deposits. The Company has not experienced any losses
on its deposits of cash and cash equivalents.
 
  Inventories
 
     Inventories are stated at the lower of cost or market. Cost is determined
using the first-in, first-out basis.
 
  Property, Plant and Equipment
 
     Property, plant and equipment is recorded at cost. Depreciation and
amortization is provided using the straight-line method over estimated useful
lives of ten to 35 years for the building and improvements; five to ten years or
the lease term, whichever is shorter, for leasehold improvements; and three to
five years for the machinery, equipment and furniture and fixtures. The
Company's policy is to regularly review the carrying amount of specialized
assets and to evaluate the remaining life and recoverability of such equipment
in light of current market conditions. Upon disposal, the assets and related
accumulated depreciation are removed from the Company's accounts, and resulting
gains or losses are reflected in operations.
 
  Warranties
 
     The Company's products are generally warranted for a period of 60 days from
customer receipt. Estimated future costs of repair, replacement, or customer
accommodations are reflected in the accompanying financial statements.
 
  Income Taxes
 
     Effective April 1, 1993, the Company adopted Statement of Financial
Accounting Standards No. 109 ("SFAS 109"), "Accounting for Income Taxes." Under
SFAS 109, the liability method is used for accounting for income taxes. There
was no material effect from adoption. The realization of deferred tax assets is
based on historical tax positions and expectations about future taxable income.
 
  Revenue Recognition
 
     Revenue is recognized upon shipment of product to the customer. Sales
figures are reported net of a provision for estimated product returns and
warranty reserves.
 
  Research and Development
 
     Research and development expenditures are charged to operations as
incurred.
 
  Foreign Currency Accounting
 
     Substantially all of the Company's sales are denominated in U.S. dollars.
Foreign currency transactions during the period are immaterial and are included
in operations.
 
  Concentration of Risks
 
     During fiscal 1995 and 1996, the Company shipped most of its thin film
disks to four customers. These four customers represented 73.7%, 5.9%, 11.2% and
1.0%, respectively and 40.5%, 35.8%, 9.1% and 6.4%, respectively, of net sales
in fiscal 1995 and 1996.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     The Company sells substantially all of its production to Asian subsidiaries
of U.S. companies. The Company performs ongoing credit evaluations of its
customers. The Company does not require collateral for its receivables and
maintains an allowance for potential credit losses.
 
     The Company's Fremont facility currently accounts for all of its
production. Disruption of operations at the Company's production facility could
cause delays in, or an interruption of, production and shipment of products,
which could materially adversely affect the Company's business, operating
results and financial condition.
 
  Public Offering
 
     During March 1996, the Company sold 8,400,000 shares of Common Stock at
$10.00 per share through its initial public offering ("IPO"), all of which were
sold by the Company. The net proceeds (after underwriter's discounts and
commissions and other costs associated with the IPO) totaled $76.9 million.
 
  Computation of Net Income Per Share
 
     Net income per share is computed using the weighted average number of
common and dilutive common equivalent shares outstanding during the period.
Dilutive common shares consist of stock options and warrants as if exercised for
all periods presented. Accretion of the Series A Preferred Stock dividend
reduces earnings available for holders of Common Stock in the computation of
earnings per share.
 
     The Company has computed common and dilutive common share equivalents in
determining the number of shares used in calculating earnings per share pursuant
to the Securities and Exchange Commission Staff Accounting Bulletin ("SAB") No.
83. SAB 83 requires the Company to include all common share equivalents issued
during the 12 months preceding the filing date of an initial public offering in
its calculation of the number of shares used to determine earnings per share as
if shares used to determine earnings per share had been outstanding for all
periods presented.
 
  Fair Value of Financial Instruments
 
   
     The carrying amounts of cash and cash equivalents, other receivables and
accrued liabilities are a reasonable estimate of their fair value due to their
short term nature. The estimated values of the Company's long term debt and
mandatorily redeemable preferred stock are based on interest rates at March 31,
1996 for issues with similar remaining maturities.
    
 
     The estimated fair value amounts of the Company's financial instruments
have been determined by the Company, using appropriate market information and
valuation methodologies. Considerable judgment is required to develop the
estimates of fair value, thus, the estimates provided herein are not necessarily
indicative of the amounts that could be realized in a current market exchange.
 
     The Company calculates the fair value of financial instruments and includes
this additional information in the notes to financial statements when the fair
value is different than the book value of those financial instruments. When the
fair value is equal to the book value no additional disclosure is made. The
Company uses quoted market prices whenever available to calculate these fair
values. When quoted market prices are not available, the Company uses standard
pricing models for various types of financial instruments which take into
account the present value of estimated future cash flows. The effect of using
different market assumptions and/or estimation methodologies may be material to
the estimated fair value amounts.

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
  Use of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
  Recent Pronouncements
 
     During March 1995, the Financial Accounting Standards Board issued
Statement No. 121, "Accounting for the Impairment of Long-Lived Assets and for
Long-Lived Assets to Be Disposed Of (SFAS No. 121)," which requires the Company
to review for the impairment of long-lived assets and intangibles whenever
events or changes in circumstances indicate that the carrying amount of an asset
may not be recoverable. In certain situations, an impairment loss would be
recognized. SFAS No. 121 will become effective for the Company's 1997 fiscal
year. The Company has studied the implications of the Statement, and based on
its initial evaluation, does not expect it to have a material impact on the
Company's financial condition or results of operations.
 
     During October 1995, the Financial Accounting Standards Board issued
Statement No. 123, "Accounting for Stock-Based Compensation (SFAS No. 123),"
which establishes a fair value based method of accounting for stock-based
compensation plans and requires additional disclosures for those companies who
elect not to adopt the new method of accounting. While the Company studies the
impact of the pronouncement, it continues to account for employees' stock
options under Accounting Principles Board(APB) Opinion No. 25, "Accounting for
Stock Issued to Employees." SFAS No. 123 will be effective for the Company's
1997 fiscal year.

     Inventories reflect reserves of approximately $4.5 million and $1.5 million
     as of March 31, 1995 and 1996, respectively. The reserve at March 31, 1995
     reflects the impact of disks contaminated during the fourth quarter of
     fiscal 1995. The decrease in inventory reserve from March 31, 1995 to March
     31, 1996 is a result of the complete disposition of the contaminated disks
     during fiscal 1996.

4. OBLIGATIONS UNDER CAPITAL LEASES
 
     In November 1995, in connection with the Leveraged Recapitalization, the
Company entered into an agreement to refinance an existing capital lease under
which the majority of assets under the existing lease plus assets with a net
book value of approximately $5.0 million were conveyed to the new

lessor. The appraised value of the assets conveyed to the new lessor exceeded
their net book value on the date transferred. The new lease agreement,
classified as a capital lease, required an initial payment of $6.1 million and
36 monthly payments of $0.2 million. Upon maturity, the Company has the option
to renew the lease or purchase the equipment at fair market value, otherwise the
lease requires a restocking fee of $1.0 million.
 
     Assets under capital lease obligations as of March 31, 1996 consist of
machinery and equipment with a cost of $26.9 million and accumulated
amortization of $10.4 million ($29.8 million and $13.9 million, respectively, at
March 31, 1995). Minimum future lease payments under capital lease obligations,
together with the present value of the net minimum lease payments, are as

5. DEBT
 
     On November 30, 1995, in connection with the Leveraged Recapitalization,
the Company paid off the entire balance of short-term borrowings and long-term
notes. The Company partially financed the Leveraged Recapitalization through a
$60.0 million senior bank term loan and $47.0 million in Subordinated Notes sold
to stockholders. The Subordinated Notes bear interest at 12.0% a year
(increasing by 1.0% a year commencing January 1, 1999). Interest on the
Subordinated Notes accrues through the earlier of July 31, 1996 or the payment
in full of the senior bank term loan. The Subordinated Notes are due in three
equal installments of principal on December 1, 2003, 2004 and 2005. While the
Subordinated Notes may be prepaid in whole or in part at the election of the
Company, the Company is obligated to prepay the Subordinated Notes from the
proceeds of certain financings after December 31, 1997.
 
     Extraordinary debt extinguishment costs, net of income taxes.  Pursuant to
the credit agreement, the Company repaid the balance of a senior bank term loan
on March 14, 1996, after completion of the IPO. As a result, the Company
recorded a one-time non-cash charge of $1.1 million (or $0.03 per share), net of
income taxes, for the write-off of the portion of unamortized debt issue costs
related to the senior bank term loan.
 
     On November 30, 1995, the Company entered into a revolving credit agreement
which provides for borrowings of up to $30.0 million. At March 31, 1996 the
Company had not drawn on this facility.
 
     The revolving credit facility is collateralized by all of the Company's
assets. The various debt agreements covering the Company's debt contain
covenants relating to quarterly profitability, minimum levels of tangible net
worth, limitations on additional debt, minimum levels of liquidity and dividend
limitations.
 
     The Company had unsecured lines of credit available which provided for
borrowings of up to $95.0 million at March 31, 1995. These unsecured lines of
credit were guaranteed by Hitachi Metals. At March 31, 1995 short term
borrowings under these agreements aggregated $86.7 million and had an interest
rate of approximately 6.5% a year.

7. MANDATORILY REDEEMABLE PREFERRED STOCK
 
   
     In connection with the Leveraged Recapitalization, the Company issued
5,900,000 shares of Series A Preferred Stock. The holders of the Series A
Preferred Stock are entitled to receive dividends at the annual rate of $1.00
per share before any dividend or other distribution may be paid to the holders
of Common Stock. Beginning on January 1, 1998 the shares of Series A Preferred
Stock will begin to accrue cumulative dividends at an annual rate of 10%. Such
dividends are senior in right of payment to any dividends declared on any shares
of the Company's capital stock, including the Common Stock. The dividends will
accrete based on the effective interest method.
    
 
     Upon any liquidation, dissolution or winding up of the Company (a
"Liquidation Event"), the holders of the Series A Preferred Stock are entitled
to receive, prior to payment of any liquidation proceeds to the holders of the
Company's capital stock, including the Common Stock, an amount equal to $10.00
plus all accrued and unpaid dividends per share of Series A Preferred Stock (the
"Preferential Amount"). A sale of all or substantially all of the Company's
assets or any consolidation or merger of the Company in which holders of the
Company's voting securities prior to such merger or consolidation hold less than
50% of the voting power of the surviving entity (a "Change in Control
Transaction") will also be regarded as a Liquidation Event and entitle the
holders of the Series A Preferred Stock to the Preferential Amount.
 
     The consent of the holders of at least two-thirds of the then outstanding
shares of the Series A Preferred Stock is required in order: (i) to redeem or
purchase any shares of the Company's Common Stock, other than repurchases of
shares from directors, officers, consultants or employees upon termination of
their relationship with the Company or from stockholders or pursuant to rights
of first refusal for the benefit of the Company, (ii) to authorize or issue any
equity security senior to, or on a parity with, the Series A Preferred Stock
with respect to dividends, liquidation preference, voting rights or otherwise or
(iii) to effect any sale of all or substantially all of the Company's assets or
any consolidation or merger or any reclassification of shares or any
recapitalization or any dissolution, liquidation or winding up of the Company.
The consent of the holders of 95% of the Series A Preferred Stock is required
for the amendment of the Company's Certificate of Incorporation if such
amendment changes the rights, preferences or privileges of the Series A
Preferred Stock or would increase the designated number of shares of Series A
Preferred Stock. The Series A Preferred Stock does not have the right to vote in
the election of directors and has no other voting rights except as described
above or required by law.
 
     The Series A Preferred Stock may be redeemed by the Company at any time, at
a redemption price equal to the Preferential Amount. The Company must redeem the
outstanding shares of Series A

Preferred Stock on January 1, 2006 for $10.00 per share. In addition, after the
Company's Subordinated Notes have been retired, the Company is obligated to
redeem shares of Series A Preferred Stock, by paying the Preferential Amount
from the proceeds of certain financing after December 31, 1997.
 
     In addition, the Board of Directors is authorized without further action by
the Company's stockholders, to issue 9,100,000 shares of Preferred Stock,
subject to the rights of the Series A Preferred Stock, in one or more series and
to fix the rights, preferences and privileges thereof.
 
8. STOCKHOLDERS' EQUITY (DEFICIT)
 
  Common Stock
 
     The holders of Common Stock are entitled to one vote per share on all
matters to be voted on by stockholders. The Series A Preferred Stock agreement
restricts dividend payments made to Common Stock holders. In the event of the
liquidation, dissolution or winding up of the Company, the holders of Common
Stock are entitled to share ratably in all assets remaining after payment of
liabilities, subject to prior liquidation rights of Series A Preferred Stock, if
any, then outstanding. The Common Stock has no preemptive rights or other
subscription rights. All outstanding shares of Common Stock are fully paid and
nonassessable.
 
     The Company has not declared or paid cash dividends as of March 31, 1996.
Under the terms of the Company's Series A Preferred Stock, no dividends may be
paid on the Common Stock unless accumulated and unpaid dividends on the Series A
Preferred Stock have been paid in full. In addition, the Company's senior bank
credit agreement prohibits the payments of cash dividends on the Common Stock
without prior approval from certain senior lenders.
 
     On April 12, 1996, the Company sold an additional 1,260,000 shares of
common stock at $10.00 per share pursuant to the underwriter's over-allotment
option, resulting in net proceeds of approximately $11.7 million.
 
  Warrants
 
   
     In connection with the Leveraged Recapitalization, the Company issued to
the Banks warrants to purchase 701,344 shares of Common Stock. During the fourth
quarter of fiscal 1996, pursuant to the terms of the warrant agreement, the
Company exercised its right to repurchase 40% of the outstanding warrants for an
immaterial amount, leaving a balance of warrants to purchase 420,794 shares of
common stock. The warrants are exercisable at a purchase price of $0.0003 per
share at any time prior to November 30, 2002.
    
 
  Stock Option Plans
 
     In November 1995, the Board of Directors authorized and reserved an
aggregate of 12,400,000 shares of Common Stock for issuance under the 1995
Management Stock Option Plan and the 1995 Stock Option Plan.
 
   
     In January 1996, the Board of Directors adopted the 1996 Non-Employee
Directors' Stock Option Plan (the "Directors' Plan") to provide for the
automatic grant of options to purchase shares of Common Stock to nonemployee
directors of the Company (other than employees or affiliates of Summit Partners,
L.P. or Hitachi Metals).
    
 
     In the event of a merger, consolidation, reverse merger or reorganization,
options outstanding under the Directors' Plan will automatically become fully
vested and will terminate if not exercised prior to such event.

     No option granted under the Directors' Plan may be exercised after the
expiration of ten years from the date it was granted. The exercise price of
options under the Directors' Plan will equal the fair market value of the Common
Stock on the date of grant. The Directors' Plan will terminate in January 2006,
unless earlier terminated by the Board of Directors.
 
     In January 1996 the Board of Directors adopted the 1996 Equity Incentive
Plan (the "Incentive Plan"). The Incentive Plan provides for grants of incentive
stock option to employees (including officers and employee directors) and of
nonstatutory stock options, restricted stock purchase awards, stock bonuses and
stock appreciation rights to employees (including officers and directors) and
consultants of the Company.
 
     The combined maximum number of shares of Common Stock authorized to be
issued pursuant to options granted under the Directors' Plan and the Incentive
Plan is 3,000,000 shares and as of March 31, 1996 no options had been granted
under these plans.

     Upon grant, 1,550,000 options vested immediately and were exercised. An
additional 1,464,048 options vested upon completion of the IPO and certain other
performance goals. The majority of remaining outstanding options will vest
ratably over a four year period. Of the options to purchase 12,284,150 shares
granted to all optionees, options to purchase 8,339,000 shares were exercised
pursuant to early exercise provisions contained in the holders' stock option
agreements. As of March 31, 1996, 4,977,055 shares of Common Stock exercised
pursuant to early exercise provisions were subject to repurchase at prices
ranging from $0.03 to $0.10 per share upon termination of employment. The
options expire no later than ten years after the date of grant.
 
  Employee Stock Purchase Plan
 
     In January 1996, the Board adopted the Employee Stock Purchase Plan (the
"Purchase Plan") covering an aggregate of 500,000 shares of Common Stock. Under
the Purchase Plan substantially all employees may be granted the opportunity to
purchase shares of common stock at 85% of the lower of the fair market value of

     Although realization of the deferred tax assets is not assured, the Company
believes that it is more likely than not that all of the deferred tax assets
will be realized. The amount of the deferred tax asset considered realizable
could be reduced if estimates of future taxable income decline significantly.
 
     At March 31, 1996, the Company had federal net operating loss carryforwards
of approximately $12.2 million available to offset future taxable income. These
net operating loss carryforwards expire in the years 2008 to 2010. Because the
Leveraged Recapitalization caused an ownership change, as

           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
defined by tax law, the Company's ability to use its net operating loss
carryforwards from November 30, 1995 is limited to a specified dollar amount
each year.
 
     Prior to the Leveraged Recapitalization, the Company was a member of a
combined group for California tax reporting purposes and began to report on a
single entity basis after the Leveraged Recapitalization. The combined group
elected the water's edge method (being that all taxable income from foreign
affiliates generated outside of the United States is excluded from the
calculation of California income tax) of reporting for California tax purposes.
The Company had a tax sharing agreement with the former combined group to pay a
share of the combined group's California tax liability through November 30,
1995. The Company's current state provision represents its share of the combined
group's California tax liability through November 30, 1995, plus its California
tax liability for the period from December 1, 1995 through March 31, 1996,
computed on a single entity basis.
 
10. 401(K) PLAN
 
     The Company has a deferred tax savings 401(k) plan and generally matches
50% of employee contributions up to 4% of gross salaries. The employer
contributions do not vest until the employee's second year of service, at which
time the contributions vest 100%. All employees employed for at least six months
are eligible to participate under the plan. The Company contributed to the plan
approximately $0.2 million per year in fiscal 1994, 1995 and $0.3 million in
fiscal year 1996.
 
11. SUBSEQUENT EVENTS
 
  Asset Purchase
 
     In May 1996, the Company purchased an aluminum substrate manufacturing
facility and other related equipment in Eugene, Oregon for approximately $5.0
million. The acquisition will be accounted for as an asset purchase, and
acquisition related expenses are not expected to have a significant impact on
first quarter fiscal 1997 results.
 
  Follow-on Offering
 
     In May 1996, the Board of Directors approved the filing of a registration
statement with the Securities and Exchange Commission covering the proposed sale
of 4,000,000 shares of Common Stock and $150.0 million par value convertible
subordinated notes.

ITEM 14.  INDEMNIFICATION OF OFFICERS AND DIRECTORS.
 
     Under Section 145 of the Delaware General Corporation Law, the Registrant
has broad powers to indemnify its directors and officers against liabilities
they may incur in such capacities, including liabilities under the Securities
Act of 1933, as amended (the "Securities Act"). The Registrant's Bylaws also
provide that the Registrant will indemnify its directors and executive officers
and may indemnify its other officers, employees and other agents to the fullest
extent not prohibited by Delaware law.
 
     The Registrant's Certificate of Incorporation provides for the elimination
of liability for monetary damages for breach of the directors' fiduciary duty of
care to the Registrant and its stockholders. These provisions do not eliminate
the directors' duty of care and, in appropriate circumstances, equitable
remedies such an injunctive or other forms of non-monetary relief will remain
available under Delaware law. In addition, each director will continue to be
subject to liability for breach of the director's duty of loyalty to the
Registrant, for acts or omissions not in good faith or involving intentional
misconduct, for knowing violations of law, for any transaction from which the
director derived an improper personal benefit, and for payment of dividends or
approval of stock repurchases or redemptions that are unlawful under Delaware
law. The provision does not affect a director's responsibilities under any other
laws, such as the federal securities laws or state or federal environmental
laws.
 
     The Registrant has entered into agreements with its directors and executive
officers that require the Registrant to indemnify such persons against expenses,
judgments, fines, settlements and other amounts actually and reasonably incurred
(including expenses of a derivative action) in connection with any proceeding,
whether actual or threatened, to which any such person may be made a party by
reason of the fact that such person is or was a director or officer of the
Registrant or any of its affiliated enterprises, provided such person acted in
good faith and in a manner such person reasonably believed to be in or not
opposed to the best interests of the Registrant and, with respect to any
criminal proceeding, had no reasonable cause to believe his or her conduct was
unlawful. The indemnification agreements also set forth certain procedures that
will apply in the event of a claim for indemnification thereunder.
 
     The Underwriting Agreement filed as Exhibit 1.1 to this Registration
Statement provides for indemnification by the Underwriters of the Registrant and
its officers and directors for certain liabilities arising under the Securities
Act or otherwise.

ITEM 15.  RECENT SALES OF UNREGISTERED SECURITIES.
 
     Since January 1993, the Registrant has sold and issued the following
unregistered securities:
 
          (1) In November 1995, the Registrant sold 21,968,057 shares of Common
     Stock to a group of accredited investors for cash in the aggregate amount
     of $708,647.
 
          (2) In November 1995, the Registrant sold 5,900,000 shares of
     Mandatorily Redeemable Series A Preferred Stock to a group of accredited
     investors for cash in the aggregate of $59,000,000.
 
          (3) In November 1995, the Registrant sold Subordinated Promissory
     Notes in the principal amount of $46,999,995 to a group of accredited
     investors for cash.
 
          (4) Since January 1993, the Registrant has granted options to purchase
     an aggregate of 12,172,150 shares of the Registrant's Common Stock to
     employees, directors and consultants under its 1995 Management Stock Option
     Plan and 1995 Stock Option Plan, at a weighted average exercise price of
     $0.04 per share. Of such options, options to purchase 7,688,000 shares have
     been exercised.
 
     The sales and issuances of securities in the transactions described in
paragraphs (1), (2) and (3) were deemed to be exempt from registration under the
Securities Act by virtue of Section 4(2) of the Securities Act and/or Regulation
D promulgated thereunder. With respect to the grant of stock options described
in paragraph (4), an exemption from registration under the Securities Act was
unnecessary in that none of such transactions involved a sale of securities as
such term is used in Section 2(3) of the Securities Act. Issuance of shares upon
exercise thereof was in reliance on Rule 701 promulgated under Section 3(b) of
the Securities Act as transactions by an issuer not involving a public offering
or transactions pursuant to compensatory benefit plans and contracts relating to
compensation as provided under Rule 701.
 
     Appropriate legends are affixed to the stock certificates issued in the
aforementioned transactions. Similar legends were imposed with any subsequent
sales of any such securities. All recipients either received adequate
information about the Registrant or had access, through employment or other
relationships, to such information.

ITEM 17.  UNDERTAKINGS.
 
     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 (the "Act") may be permitted to directors, officers, and controlling
persons of the Registrant pursuant to the provisions described in Item 14 or
otherwise, the Registrant has been advised that in the opinion of the Securities
and Exchange Commission such indemnification is against public policy as
expressed in the Act and is, therefore, unenforceable.
 
     The undersigned Registrant hereby undertakes that: (1) for purposes of
determining any liability under the Act, the information omitted from the form
of prospectus as filed as part of the registration statement in reliance upon
Rule 430A and contained in the form of prospectus filed by the Registrant
pursuant to Rule 424(b)(1) or (4) or 497(h) under the Act shall be deemed to be
part of the registration statement as of the time it was declared effective, and
(2) for the purpose of determining any liability under the Act, each
post-effective amendment that contains a form of prospectus shall be deemed to
be a new registration statement relating to the securities offered therein, and
the offerings of such securities at that time shall be deemed to be the initial
bona fide offerings thereof.

Ladies and Gentlemen:

        You have requested our opinion with respect to certain matters in
connection with the filing by HMT Technology Corporation (the "Company") of a
Registration Statement on Form S-1 (the "Registration Statement") with the
Securities and Exchange Commission (the "Commission") under the Securities Act
of 1933, as amended, covering (i) an underwritten public offering of up to
4,600,000 shares of Common Stock (the "Common Stock") and (ii) up to an
aggregate principal amount of $172.5 million Convertible Subordinated Notes due
2003 (including $22,500,000 principal amount of Notes subject to the
Underwriter's over-allotment option) (the "Notes") to be issued under an
Indenture, in substantially the form as  filed on May 29, 1996 in Exhibit 4.3
to the Registration Statement, to be executed by the  Company and State Street
Bank & Trust Company, as Trustee (the "Indenture").  The Common Stock and the
Notes are to be sold pursuant to underwriting  agreements to be entered into
between the Company and the Underwriters named in the Registration Statement
(the "Underwriting Agreement for Common Stock" and  the "Underwriting Agreement
for Notes," referred to collectively as the "Underwriting Agreements").

In connection with this opinion, we have (i) examined and relied upon the
Registration Statement and related Prospectus, the Company's Restated
Certificate of Incorporation, as amended, and Amended and Restated Bylaws, and
the originals or copies certified to our satisfaction of such records,
documents, certificates, memoranda and other instruments as in our judgment are
necessary or appropriate to enable us to render the opinion expressed below,
(ii) assumed that the Restated Certificate of Incorporation, as amended, as set
forth in Exhibit 3.2 incorporated by reference in the Registration Statement,
shall have been duly approved and filed with the office of the Delaware
Secretary of State and (iii) that the shares of Common Stock will be sold by
the Underwriters at a price established by the Pricing Committee of the Board
of Directors of the Company (the "Pricing Committee"), (iv) that the Indenture
will constitute a binding obligation of the Trustee in accordance with its
terms, (v) that the interest rate, conversion price and other remaining terms
of  the Indenture shall have been fixed and approved by the Pricing Committee,
and (vi) with respect to the enforceability of the Notes we have assumed that
the laws of the State of New York are the same in all material respects as the
laws of the State of California.        

Our opinion is expressed only with respect to the federal laws of the
United States of America and the laws of the State of California. We express no
opinion as to whether the laws of any particular jurisdiction apply and no
opinion to the extent that the laws of the jurisdictions other than those
identified above are applicable to the matter hereof. We are not rendering any
opinion as to compliance with any antifraud law, rule or regulation relating to
securities, or to the sale or issuance thereof. 

On the basis of the foregoing, and in reliance thereon, we are of the
opinion that:

                  (a) the Common Stock, when sold and issued in accordance with
         the Registration Statement and related Prospectus, will be validly
         issued, fully paid and nonassessable; and

                  (b) upon (i) the due execution and delivery of the Indenture
         and (ii) the due execution, authentication, issuance and delivery of
         the Notes to the purchasers thereof against payment of the purchase
         price therefor as provided in the Underwriting Agreement for Notes, the
         Notes will constitute binding obligations of the Company, except as may
         be limited by bankruptcy, insolvency or other similar laws affecting
         the enforcement of creditors' rights in general. The enforceability of
         the Company's obligations under the Notes is subject to general
         principles of equity (regardless of whether such enforceability is
         considered in a proceeding in equity or at law).

We consent to the reference to our firm under the caption "Legal Matters" in the
Prospectus included on the Registration Statement and to the filing on this 
opinion as an exhibit to the Registration Statement.

Very truly yours,
