                               PROSPECTUS SUMMARY
 
    THE FOLLOWING SUMMARY IS QUALIFIED IN ITS ENTIRETY BY THE MORE DETAILED
INFORMATION AND THE CONSOLIDATED FINANCIAL STATEMENTS AND NOTES THERETO
APPEARING ELSEWHERE IN THIS PROSPECTUS. FOR A DISCUSSION OF CERTAIN MATTERS THAT
SHOULD BE CONSIDERED BY PROSPECTIVE PURCHASERS OF THE COMMON STOCK OFFERED
HEREBY, SEE "RISK FACTORS."
 
                                  THE COMPANY
 
    Overland designs, develops, manufactures, markets and supports magnetic tape
data storage systems used by businesses for backup, archival and data
interchange functions. The Company primarily offers three product lines --
LibraryXpress, TapeXpress and TapePro -- which are designed to meet the data
storage needs of client/server networks, workstations, minicomputers and
personal computers. Overland believes that it is well positioned to take
advantage of the rapidly increasing demand for storage capacity, particularly
that created by the growth in client/server networks. To address this growing
network storage demand, Overland introduced the LXB in March 1996, the first
product of its LibraryXpress line of automated tape libraries. In August 1996,
BYTE Magazine selected the LXB as the "Best Overall DLT Tape Library." The
Company believes that, with the anticipated delivery of the related LXG control
unit during the first quarter of calendar year 1997, LibraryXpress will
constitute the first automated tape library in its capacity class that is truly
"scalable," in that it is designed to allow end-users to configure combinations
of drives and cartridges as their storage requirements change without having to
replace their existing Overland units. Management believes that LibraryXpress
has significant market potential because it is designed to enable companies to
increase their storage capacity in a cost effective manner as their businesses
grow.
 
    The Company's TapeXpress product line consists of 18/36-track tape drives
and loaders based on an IBM standard and, in October 1996, IBM selected the
Company to be a supplier of 36-track products. With its TapePro product line,
Overland is a leading supplier of 9-track reel-to-reel products used in data
interchange. In addition, the Company distributes a line of DLT-based products
manufactured by Quantum and markets various other products, including controller
cards which connect its tape drives to personal computers, interchange software,
storage management software supplied by third parties, spare parts and tape
media. With the exception of the tape drives in its LibraryXpress product line,
all of the Company's products are designed and manufactured in-house. The
Company's products combine electro-mechanical robotics, electronic hardware and
firmware, which are developed by the Company with an emphasis on efficiency of
design, functionality and reliability.
 
INDUSTRY OVERVIEW
 
    The data storage industry has experienced rapid growth in recent years in
response to the significant increase in the amount of electronically stored
data. Overland believes that this growth will continue due to (i) the
introduction of increasingly powerful computing platforms, (ii) the spreading
use of computers for tasks that previously were performed manually, (iii) the
increasing number, size, bandwidth and complexity of computer networks,
particularly client/server networks, (iv) the rapid growth of data-intensive
applications and (v) the growth of intranet and Internet based computing. In
addition, emerging data intensive applications, such as still image, motion
video, check imaging and other multimedia and character recognition uses, are
accelerating the demand for data storage solutions.
 
    Current data storage solutions provide secure, high capacity data
repositories based primarily on three technologies -- magnetic tape, magnetic
disk and optical disk. Magnetic tape remains the most cost effective storage
medium (at approximately one-fifth of the cost per megabyte stored as compared
to magnetic or optical disk), and is used most often for backup and archival
functions. The development of automated tape libraries, which address the
historically high degree of costly human intervention involved in using tape
storage, is helping to drive the expanded use of magnetic tape. Automated tape
libraries also provide improved throughput, increased data capacity and
unattended operation through the use of multiple drives and cartridges. In
addition, business managers are increasingly perceiving data to be critical at a
company-wide level as opposed to only being important at the individual
workstation level. As a result, central management of data has been increasing.
 
                                       3
<PAGE>
    The Company believes that the factors noted above will greatly increase the
number of sites worldwide requiring large amounts of backup and, therefore, the
need for advanced storage solutions. According to Strategic Research Corp., a
storage management industry consultant, the number of centralized storage sites
worldwide requiring more than 200GB of backup is projected to grow from
approximately 116,000 sites in 1996 to 660,000 sites by the year 2000. The
Company believes that it is in a strong position to capitalize on the
opportunities created by this projected growth.
 
COMPANY STRATEGY
 
    Overland intends to continue building a leadership position in the magnetic
tape segment of the data storage industry. The Company believes that it
possesses certain core competencies which will help it attain this leadership
position, including: (i) advanced knowledge of hardware/software integration and
connectivity, due to its experience in designing and developing both tape drives
and libraries; (ii) experience in the magnetic tape industry, particularly with
respect to innovative mechanical, electrical and firmware designs; (iii)
comprehensive understanding of, and close contact with, end-user needs; and (iv)
experienced management and developed management processes in each functional
area of its business operations. The Company intends to leverage these core
competencies in the execution of its business strategy, which includes the
following elements:
 
    - EMPHASIZE DEVELOPMENT OF ADVANCED STORAGE SOLUTIONS.  Overland invests
      extensively in research and development in order to deliver technologies
      for the "next generation" of magnetic tape drives and automated tape
      libraries. The Company intends to continue its research and development
      efforts in areas that build upon its manufacturing, engineering and
      operational strengths in order to offer products which serve emerging data
      storage needs.
 
    - MAINTAIN LEADERSHIP IN PRODUCT RELIABILITY.  The Company believes that
      product dependability is crucial for its customers. Overland believes that
      it has achieved a reputation for reliability and intends to continue to
      develop and offer high quality and reliable products and augment this
      reliability with comprehensive technical support.
 
    - LEVERAGE CLOSE RELATIONSHIPS WITH END-USERS.  The Company believes that
      its interaction with end-users enables it to better understand the
      evolving product and application needs of its customers. Overland intends
      to continue its close contact with end-users by selling its products
      directly to them, by involving them in ongoing market research activities
      regarding future products, and by responding to their technical support
      requirements.
 
    - FURTHER DEVELOP WORLDWIDE DISTRIBUTION.  Overland intends to increase the
      number of distributors in its existing international markets, develop
      additional distribution channels in these markets for new product
      introductions and establish appropriate distribution channels for its
      current and future products in new international markets.
 
    - HARVEST LEGACY MARKETS.  The markets served by the Company's 9-track and
      18-track product lines are characterized by mature technologies and large
      installed customer bases. Overland intends to capitalize on its position
      in these markets in order to capture additional market share and expects
      to realize improved operating margins as such products require limited
      research and development support as compared to newer technology.
 
    - PURSUE ALLIANCES OR ACQUISITIONS.  Overland believes that it may be able
      to expand and increase the value-added component of its product offerings
      through alliances with, or acquisitions of, complementary businesses. The
      Company intends to evaluate strategic product and technology acquisitions
      and may pursue second source manufacturing arrangements to further
      capitalize upon its engineering, manufacturing and quality process
      capabilities.

RAPID TECHNOLOGICAL CHANGE AND DEPENDENCE ON NEW PRODUCT DEVELOPMENT
 
    The market for the Company's products is generally characterized by rapid
technological change and evolving industry standards and is highly competitive
with respect to timely innovation. The future success of the Company will depend
on its ability to anticipate changes in technology, to develop new and enhanced
products on a timely and cost-effective basis and to introduce, manufacture and
achieve market acceptance of such new and enhanced products. In particular, the
Company's future success is dependent on its LibraryXpress product line, the
initial product of which, the LXB, commenced shipment in March 1996. During the
first quarter of calendar year 1997, the Company intends to commence shipment of
the LXG global control unit of the LibraryXpress product line, which will create
what the Company believes will be the first automated tape library in its
capacity class which is truly "scalable." Prototypes of the LXG were shipped in
November 1996. The LXB and the other planned units of the LibraryXpress product
line have not yet achieved widespread market acceptance and are anticipated to
confront increasing competition both from competitive automated tape library
products, as well as other storage devices that may be developed in the future.
The DLT tape drives used by the Company in its LibraryXpress products are
obtained from a sole supplier, Quantum Corporation ("Quantum"), which from time
to time has placed customers such as the Company (and its competitors) on
allocation due to shortages of its components. See "--Dependence on Certain
Suppliers." Development schedules for high technology products are inherently
subject to uncertainty and there can be no assurance that the Company will be
able to meet its product development schedules, including those for the
LibraryXpress product line, or that development costs will be within budgeted
amounts. If the products or product enhancements that the Company develops are
not deliverable due to developmental problems, quality issues or component
shortage problems or if such products or product enhancements do not achieve
market acceptance or are unreliable, the Company's business, financial condition
and results of operations may be materially and adversely affected. The
introduction (whether by the Company or its competitors) of new products
embodying new technology such as new sequential or random access mass storage
devices and the emergence of new industry standards can render existing products
obsolete or not marketable. For example, the Company believes that its sales of
Quantum products which it distributes declined from $2.5 million in the first
quarter of fiscal year 1996 to $819,000 in the first quarter of fiscal year
1997, largely as a result of a decline in sales of the Quantum DLT
2500/2700/4500/4700 loaders which have been replaced by the Company's sales of
the LXB, which amounted to approximately $1.9 million in revenues during the
first quarter of fiscal year 1997. Similarly, the Company anticipates a
continued migration by users of its 18-track products to its 36-track products.
In addition, 9-track product sales of $3.1 million in the first quarter of
fiscal year 1997 declined 32.5% from the first quarter of fiscal year 1996,
reflecting the general maturity of the 9-track tape technology and a movement by
the Company's customers to more technologically advanced products. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations," "Business--Products" and "--Research and Development."
 
COMPETITION AND PRICE PRESSURE
 
    The worldwide tape storage market is intensely competitive as a large number
of manufacturers of alternative tape technologies compete for a limited number
of customers and barriers to entry are
 
                                       6
<PAGE>
relatively low in the library category. The Company currently participates in
three market areas which are defined by different tape technologies: (i) network
data storage; (ii) data backup and interchange based on IBM compatible 3480/3490
technology; and (iii) data interchange based on 9-track reel-to-reel technology.
In each of these areas, many of the Company's competitors have substantially
greater financial and other resources, larger research and development staffs,
and more experience and capabilities in manufacturing, marketing and
distributing products than the Company. For network data storage, the
LibraryXpress LXB product currently competes with products made by Advanced
Digital Information Corporation ("ADIC"), ATL Products, Inc. ("ATL/Odetics"),
Breece Hill Technologies, Inc. ("Breece Hill"), Hewlett-Packard Company
("Hewlett-Packard"), Quantum and Storage Technology Corporation ("Storage
Technology"), and the Company believes that additional competitors can be
expected to enter the market. For the data backup and interchange market, which
is based on IBM compatible 3480/3490 technology, the Company offers a product
line of 18 and 36-track products, which the Company believes compete primarily
with products made by Fujitsu Computer Products of America, Inc. ("Fujitsu"),
Hitachi Data Systems Corporation ("Hitachi"), Laser Magnetic Storage and Storage
Technology. For the 9-track data interchange market, the Company believes it
competes with Anritsu American Incorporated, Hewlett-Packard and M4 Data, Inc.
Except for the 9-track data interchange market, the markets for the Company's
products are characterized by significant price competition, and the Company
anticipates that its products will face increasing price pressure. This pressure
could result in significant price erosion, reduced profit margins and loss of
market share, which could have a material adverse effect on the Company's
business, financial condition and results of operations. See
"Business--Competition."
 
DEPENDENCE ON CERTAIN SUPPLIERS
 
    The Company's products have a large number of components and subassemblies
produced by outside suppliers and it is highly dependent on such suppliers for
components and subassemblies, including DLT tape drives, read-write heads,
printed circuit boards and integrated circuits, which are essential to the
manufacture of the Company's products. In addition, for certain of these items,
the Company qualifies only a single source, which can magnify the risk of
shortages and decrease the Company's ability to negotiate with its suppliers on
the basis of price. If such shortages occur, or if the Company experiences
quality problems with suppliers, shipments of products could be significantly
delayed or costs significantly increased, which would have a material adverse
effect on the Company's business, financial condition and results of operations.
Specifically, the Company's new LibraryXpress automated tape libraries
incorporate DLT tape drives manufactured by Quantum, which is also a competitor
of the Company in that Quantum markets its own tape drives and tape loader
products. Currently, there are no alternative sources for the DLT tape drives
supplied by Quantum. The Company does not have a long-term contract with
Quantum, which could cease supplying DLT tape drives directly to the Company.
From time to time in the past, the Company has not been able to obtain as many
drives as it has needed from Quantum due to drive shortages or quality issues.
Any prolonged inability to obtain adequate deliveries could require the Company
to pay more for components, parts and other supplies, seek alternative sources
of supply, delay shipment of products and damage relationships with current and
prospective customers. Any such delay or damage could have a material adverse
effect on the Company's business, financial condition and results of operations.
During the past 12 months, the Company has experienced problems with the quality
and timeliness of the supply of DLT drives and read-write heads, each of which
is a sole source component. Such problems have adversely affected the Company's
sales during this period. While the Company believes that the problems relating
to these components have been resolved, no assurance can be given that such
problems will not re-occur or that the Company will not experience similar or
more serious disruptions in supply in the future. See "Business--Products" and
"--Manufacturing."
 
DEPENDENCE ON A LIMITED NUMBER OF CUSTOMERS
 
    The Company markets its products to original equipment manufacturers
("OEMs"), value-added resellers ("VARs"), systems integrators, distributors,
resellers and end-user customers. The Company's
 
                                       7
<PAGE>
sales to its top five customers accounted for 34% of the Company's total sales
in fiscal year 1996, with Digital Equipment Corporation ("DEC"), a major
customer since 1993, accounting for 23% of such sales. In October 1996, the
Company signed a five-year agreement with IBM to supply its 36-track products.
The Company anticipates that the percentage of its sales to these top two
customers will increase significantly during fiscal year 1997 and could account
for as much as 30% of the Company's sales. As is typical in the industry, the
Company's OEM contracts provide for annual price reviews and the customers are
not required to purchase minimum quantities. Orders may be rescheduled or
canceled outside 30 days of shipment without penalty. The loss of one or more of
these customers due to competition from other vendors, consolidation,
substantial cancellations by them, or the receipt of orders below anticipated
amounts would have a material adverse effect on the Company's business,
financial condition and results of operations. See "Business--Sales and
Marketing."
 
FLUCTUATIONS IN RESULTS
 
    The Company's results can fluctuate substantially from time to time for
various reasons. All of the markets served by the Company are volatile and
subject to market shifts, which may or may not be discernible in advance by the
Company. A slowdown in the demand for workstations, mid-range computer systems
and networks could have a significant adverse effect on the demand for the
Company's products in any given period. The Company has experienced delays in
receipt of purchase orders and, on occasion, anticipated purchase orders have
been rescheduled or have not materialized due to changes in customer
requirements. The Company's customers may cancel or delay purchase orders for a
variety of reasons, including the rescheduling of new product introductions,
changes in their inventory practices or forecasted demand, general economic
conditions affecting the computer market, changes in pricing by the Company and
its competitors, new product announcements by the Company or others, quality or
reliability problems related to the Company's products, or selection of
competitive products as alternate sources of supply. In addition, because a
large portion of the Company's sales are generated by its European distributor
channel (20% in fiscal year 1996), the first fiscal quarter (July through
September) is impacted by seasonally slow European orders, reflecting the summer
holiday period in Europe. The Company's operations may reflect substantial
fluctuations from period to period as a consequence of such industry shifts,
price erosion, general economic conditions affecting the timing of orders from
customers, as well as other factors discussed herein. In particular, the
Company's ability to forecast sales to distributors and VARs and, increasingly
to OEMs, is especially limited as such customers typically provide the Company
with relatively short order lead times or are permitted to change orders on
short notice, respectively. A portion of the Company's expenses are fixed and
difficult to reduce should revenues not meet the Company's expectations, thus
magnifying the material adverse effect of any revenue shortfall. The Company's
gross profit has fluctuated and will continue to fluctuate quarterly and
annually based upon a variety of factors such as the level of utilization of the
Company's production capacity, changes in product mix, average selling prices,
demand or manufacturing yields, increases in production and engineering costs
associated with initial production of new programs, changes in the cost of or
limitations on availability of materials and labor shortages. During the first
quarter of fiscal year 1997, the Company reported a gross margin of 37% which
was higher than its average quarterly gross margin during fiscal years 1994,
1995 and 1996. Management does not believe that this gross margin level, which
was positively affected by an increase in the sales of the LibraryXpress and a
decrease in sales of distributed product, will be maintained. Generally, new
products have higher gross margins than more mature products. Therefore, the
Company's ability to introduce new products in a timely fashion is an important
factor to its profitability. Based upon all of the foregoing, the Company
believes that period-to-period comparisons of its revenues and operating results
will continue to fluctuate and are not necessarily meaningful and should not be
relied on as indications of future performance. Furthermore, in some future
quarter the Company's revenues and operating results could be below the
expectations of public market analysts or investors, which could result in a
material adverse effect on the price of the Common Stock. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations."
 
                                       8
<PAGE>
REPLACEMENT OF INFORMATION SYSTEMS
 
    In July 1996, the Company began a project to replace its enterprise-wide
information and business systems by the end of fiscal year 1997 to more
effectively address the complexities of the Company's business and to support
its growth in the next five years. Although the Company has not experienced any
delays in this effort to date, there can be no assurance that future delays in
the implementation process will not occur. The failure to successfully
accomplish the replacement of these systems in a timely manner, or any failure
otherwise to achieve the necessary levels of information and business system
support, could have a material adverse effect on the Company's business,
financial condition and results of operations.
 
RISKS RELATED TO FOREIGN SOURCING AND FOREIGN SALES
 
    Because a number of the Company's key components are currently manufactured
in Singapore and Korea, its results of operations can be affected by
fluctuations in currency exchange rates. The Company's international procurement
is also subject to certain other risks common to foreign operations in general,
including government regulation and import restrictions. In particular, an
adverse foreign exchange movement of the U.S. dollar versus the Singapore dollar
or other currency, or the imposition of import restrictions or tariffs by the
U.S. government on products or components shipped from Singapore, Korea or
another country could have a material adverse effect on the Company's business,
financial condition and results of operations. In addition, because of the
Company's use of components produced overseas, the sale of the Company's
products to domestic federal or state agencies may be restricted by limitations
imposed by the Buy American Act or the Trade Agreement Act. See
"Business--Manufacturing."
 
    Direct international sales accounted for 27% of sales in fiscal year 1996
and the Company expects that international sales will continue to grow and
represent an even greater proportion of the Company's revenue. Sales to
customers outside the U.S. are subject to various risks, including the
imposition of governmental controls, the need to comply with a wide variety of
foreign and U.S. export laws, political and economic instability, trade
restrictions, changes in tariffs and taxes, longer payment cycles typically
associated with international sales, the greater difficulty of administering
business overseas. Furthermore, although the Company endeavors to meet standards
established by foreign regulatory bodies, there can be no assurance that the
Company will be able to comply with changes in foreign standards in the future.
The inability of the Company to design products that comply with foreign
standards could have a material adverse effect on the Company. Currently, all of
the Company's sales are U.S. dollar denominated and fluctuations in the value of
foreign currencies relative to the U.S. dollar could therefore make the
Company's products less price competitive. However, the Company has plans to
expand its presence in Europe through its operation in the United Kingdom in the
last half of fiscal year 1997 and to bill customers for product shipped from
England in other foreign currencies. When this occurs, a decrease in the value
of the other foreign currencies in relation to the U.S. dollar after
establishing prices and before receipt of payment by the Company would have an
adverse effect on the Company's business, financial condition and results of
operations. See "Business--Sales and Marketing."
 
DEPENDENCE ON KEY EMPLOYEES
 
    The Company's future success depends in large part on its ability to retain
certain key executives and other key personnel, many of whom have been
instrumental in developing new technologies and setting strategic plans. The
Company's growth and future success will depend in large part on its continuing
ability to hire, motivate and retain highly qualified management, technical,
sales and marketing team members. Competition for such personnel is intense and
there can be no assurance that the Company will be able to retain its existing
personnel or attract additional qualified personnel in the future. See
"Management."
 
TECHNOLOGY AND INTELLECTUAL PROPERTY
 
    The Company believes that, because of the rapid pace of technological change
in the tape storage industry, patent and trade secret protection are less
significant than factors such as the knowledge, ability
 
                                       9
<PAGE>
and experience of the Company's personnel, new product introductions and product
enhancements. Nonetheless, the Company's ability to compete effectively depends
in part on its ability to develop and maintain proprietary aspects of its
technology. There can be no assurance that any future patents will be granted or
that any patents will be valid or provide meaningful protection for the
Company's product innovations. In addition, the laws of certain foreign
countries may not protect the Company's intellectual property to the same extent
as U.S. laws. Furthermore, there can be no assurance that others will not
independently develop similar products, duplicate the Company's products or, if
patents are issued to the Company, design around the patents issued to the
Company. The Company also relies on a combination of copyright, trademark, trade
secret and other intellectual property laws to protect its proprietary rights.
Such rights, however, may not preclude competitors from developing substantially
equivalent or superior products to those of the Company's. In addition, many
aspects of the Company's products are not subject to significant intellectual
property protection. While the Company is not currently engaged in any
intellectual property litigation or proceedings, there can be no assurance that
it will not become so involved in the future or that its products do not
infringe any intellectual property or other proprietary right of any third
party. An adverse outcome in litigation or similar proceedings could subject the
Company to significant liabilities to third parties, require disputed rights to
be licensed from others or require the Company to cease marketing or using
certain products, any of which could have a material adverse effect on the
Company's business, financial condition and results of operations. See
"Business-- Proprietary Rights."
 
RISKS ASSOCIATED WITH POSSIBLE ACQUISITIONS
 
    The Company may in the future pursue acquisitions of complementary
businesses, products or technologies as it seeks to expand and increase the
value-added component of its product offerings. Acquisitions involve numerous
risks, including difficulties in the assimilation of the operations and
personnel of the acquired business, the diversion of management's attention from
other business concerns, risks of entering markets in which the Company has no
direct prior experience, and the potential loss of key employees of the acquired
business. In addition, future acquisitions by the Company may result in
potentially dilutive issuances of equity securities and the incurrence of
additional debt and amortization expenses related to goodwill and other
intangible assets which could adversely affect the Company's business, financial
condition and results of operations.
 
WARRANTY EXPOSURE
 
    The Company generally provides a two-year, return-to-factory warranty on its
products. For certain products, it provides a two-year on-site warranty which is
supplied by a third party service provider. The Company pays the service
provider in advance the negotiated price of the contract and the service
provider is then responsible for the costs of providing warranty service during
the term of the contract. For products which the Company distributes and for
tape drives used in the Company's products but manufactured by a third party,
the Company passes on to the customer the related manufacturer's warranty.
Although the Company has established reserves for the estimated liability
associated with product warranties, there can be no assurance that such reserves
will be adequate or that the Company will not incur substantial warranty
expenses in the future with respect to new or established products. See
"Business--Customer Service and Support."
 
MANAGEMENT DISCRETION OVER PROCEEDS OF THE OFFERING
 
    The Company intends to use approximately $3.3 million of the net proceeds of
this Offering to repay outstanding indebtedness and approximately $  million for
general corporate purposes, including working capital and possible acquisitions
of complementary businesses, products and technologies, although the Company
currently has no agreements or commitments with respect to any such
transactions. Accordingly, the Company will have broad discretion as to the
application of such proceeds. An investor will not have an opportunity to
evaluate the economic, financial and other relevant information which will be
utilized by the Company in determining the application of such proceeds. See
"Use of Proceeds."
 
                                       10
<PAGE>
ABSENCE OF PRIOR PUBLIC MARKET FOR COMMON STOCK; POSSIBLE VOLATILITY OF STOCK
  PRICE
 
    Prior to this Offering, there has been no public trading market for the
Common Stock, and there can be no assurance that an active trading market will
develop or be sustained after this Offering. The stock market has from time to
time experienced extreme price and volume fluctuations which often have been
unrelated to the operating performance of particular companies. Announcements of
new products or accounts by the Company or its competitors, changes in earnings
estimated by analysts and economic and other external factors, as well as
period-to-period fluctuations in financial results of the Company, may have a
significant impact on the market price and marketability of the Common Stock.
Fluctuations or decreases in the trading price of the Common Stock may adversely
affect the liquidity of the trading market for the Common Stock and the
Company's ability to raise capital through future equity financing.
See--"Fluctuations in Results." The initial public offering price of the Common
Stock in this Offering will be determined by negotiations among the Company, the
Selling Shareholders and the Representatives of the Underwriters based on
several factors and may not be indicative of prices that will prevail in the
trading market. See "Principal and Selling Shareholders," "Shares Eligible for
Future Sale" and "Underwriting."
 
IMMEDIATE AND SUBSTANTIAL DILUTION; ABSENCE OF DIVIDENDS
 
    The initial public offering price per share of the Common Stock will exceed
the net tangible book value per share of the Common Stock. Accordingly, the
purchasers of shares of Common Stock in this Offering will experience immediate
and substantial dilution of net tangible book value per share of $    . The
Company has not paid any dividends on its Common Stock and does not anticipate
paying any dividends on such stock in the foreseeable future. In addition, the
Company's current bank credit line prohibits the payment of dividends. See
"Dilution" and "Dividend Policy."
 
EFFECT ON SHARE PRICE OF SHARES ELIGIBLE FOR FUTURE SALE
 
    Upon completion of this Offering, the 2,700,000 shares offered hereby
(3,105,000 shares if the over-allotment option is exercised in full) will be
eligible for immediate sale in the public market without restriction unless they
are held by affiliates of the Company. After the completion of this Offering,
7,042,898 of the outstanding shares will be "restricted securities" within the
meaning of Rule 144 ("Rule 144") promulgated under the Securities Act of 1933,
as amended, and may not be sold in the absence of registration under the
Securities Act unless an exemption from registration is available. However,
substantially all of these shares will be eligible for sale pursuant to Rule 144
beginning 90 days after the completion of this Offering, subject to the volume
and manner of sale limitations of Rule 144. The directors, officers and current
shareholders of the Company, beneficially holding (upon completion of this
Offering) an aggregate of 6,306,985 shares, have agreed not to sell or otherwise
dispose of any such shares for at least 180 days from the date of this
Prospectus without the prior written consent of Jefferies & Company, Inc.
Thereafter, these shares will generally be eligible for immediate sale in the
public market without restriction. Furthermore, certain of the Company's current
shareholders and the holder of the Company's outstanding warrant have been
granted certain "piggy-back" registration rights with respect to the shares of
Common Stock owned by them or to be issued to them. The Company intends to file
a registration statement under the Securities Act concurrent with this Offering
covering the sale of shares of Common Stock under its 1996 Employee Stock
Purchase Plan and its various stock option plans. No predictions can be made as
to the effect, if any, that public 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 the Common Stock in the public
market, particularly by directors and officers of the Company, or the perception
that such sales could occur, could have an adverse impact on the market price of
the Common Stock. See "Principal and Selling Shareholders," "Shares Eligible for
Future Sale" and "Underwriting."
 
FAIR PRICE PROVISION
 
    The Company anticipates amending its Articles of Incorporation prior to the
completion of this Offering to include a "fair price" provision that may have
the effect of discouraging persons from pursuing a non-negotiated takeover of
the Company and preventing certain changes of control. See "Description of
Capital Stock."

                                USE OF PROCEEDS
 
    The net proceeds to the Company from the sale of the 2,200,000 shares of
Common Stock being offered by the Company hereby are estimated to be
approximately $        , based upon an assumed initial offering price of
$        per share and after deducting underwriting discounts and estimated
offering expenses ($        if the Underwriters' over-allotment option is
exercised in full and such shares are purchased from the Company). All shares
purchased pursuant to the exercise of the Underwriters' over-allotment option
will be sold by the Company. The Company will not receive any proceeds from the
sale of Common Stock by the Selling Shareholders.
 
    Approximately $3.3 million of the net proceeds of this Offering will be used
by the Company for the repayment of outstanding indebtedness under its revolving
line of credit as of September 30, 1996, which bears interest at the bank's
prime rate plus 0.50%. The remaining net proceeds will be used by the Company
for general corporate purposes including working capital, development of new
technologies and possible acquisitions of complementary businesses, products or
technology, although no such acquisitions are being negotiated by the Company at
the present time and there can be no assurance that such acquisitions will be
made. Pending the use of the net proceeds for the above purposes, the Company
intends to invest the net proceeds from this Offering in investment-grade,
short-term, interest-bearing securities.
 
                                DIVIDEND POLICY
 
    The Company has not paid cash dividends on its Common Stock to date and does
not anticipate doing so in the foreseeable future. The Company currently intends
to retain its earnings to provide funds for the operation and expansion of its
business. In addition, the Company's current bank line of credit prohibits the
payment of cash dividends on its capital stock without the bank's prior written
consent. See Note 4 of the Notes to Consolidated Financial Statements.

                                 CAPITALIZATION
 
    The following table sets forth the actual capitalization of the Company as
of September 30, 1996 (i) on a historical basis and (ii) as adjusted to give
effect to the conversion of all of the Company's Preferred Stock into Common
Stock and the application of the net proceeds from the sale of 2,200,000 shares
of Common Stock offered by the Company hereby at an assumed initial offering
price of $      per share and after deducting the underwriting discount and
estimated offering expenses payable by the Company. See "Use of Proceeds." This
table should be read in conjunction with the Company's Consolidated Financial
Statements, and the notes thereto, included elsewhere herein.

                                    DILUTION
 
    The pro forma net tangible book value of the Company as of September 30,
1996 was $11,366,000, or $1.51 per share. Pro forma net tangible book value per
share is determined by dividing the tangible net worth of the Company (total
assets less intangible assets and total liabilities) by the number of
outstanding shares of Common Stock after giving effect to the conversion of all
outstanding shares of the Company's Preferred Stock into Common Stock upon the
completion of this Offering. Without taking into account any changes in such net
tangible book value after September 30, 1996, other than to give effect to the
sale of the 2,200,000 shares of Common Stock offered by the Company at an
assumed initial public offering price of $      per share, pro forma net
tangible book value of the Company as of       would have been approximately
$      or $      per share (after deducting the estimated underwriting discount
and offering expenses payable by the Company). This represents an immediate
increase in net tangible book value of $      per share to existing shareholders
and an immediate dilution of $      per share to new investors. Dilution to new
investors is determined by subtracting the net pro forma tangible book value per
share after this Offering from the initial public offering price per share. The
following table illustrates this per share dilution:

- ------------------------
(1) The Company's effective tax rate for the year ended June 30, 1996 was
    affected in the fourth quarter of the year by a one-time tax valuation
    allowance adjustment, which reduced income tax expense and correspondingly
    increased net income by $997,000, or $    per share. Without this
    adjustment, for the year ended June 30, 1996 net income and net income per
    share would have been $2,162,000 and $    , respectively.
 
(2) See Note 1 of Notes to Consolidated Financial Statements for an explanation
    of shares used in computing net income (loss) per share.
 
(3) In 1993, the Board of Directors approved a change in the Company's fiscal
    year to June 30 from August 31. Consequently, the consolidated financial
    statements for the period ended June 30, 1993 reflect ten months of actual
    results.

                    MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
    THIS PROSPECTUS CONTAINS FORWARD-LOOKING STATEMENTS THAT INVOLVE RISKS AND
UNCERTAINTIES. THE COMPANY'S ACTUAL RESULTS COULD DIFFER MATERIALLY FROM THOSE
DISCUSSED HEREIN. FACTORS THAT COULD CAUSE OR CONTRIBUTE TO SUCH DIFFERENCES
INCLUDE, BUT ARE NOT LIMITED TO, THOSE DISCUSSED IN THIS SECTION, "RISK FACTORS"
AND "BUSINESS," AS WELL AS THOSE DISCUSSED ELSEWHERE IN THIS PROSPECTUS. THE
FOLLOWING DISCUSSION AND ANALYSIS SHOULD BE READ IN CONJUNCTION WITH THE
COMPANY'S CONSOLIDATED FINANCIAL STATEMENTS, AND NOTES THERETO, APPEARING
ELSEWHERE IN THIS PROSPECTUS.
 
GENERAL
 
    Overland designs, develops, manufactures, markets and supports magnetic tape
data storage systems used by businesses for backup, archival and data
interchange functions. The Company's products are based on three different
half-inch magnetic tape technologies. In March 1996, the Company commenced
shipment of the LXB, an automated tape library base unit and the first product
in its LibraryXpress product line. The LXB is an expandable automated tape
library based on DLT tape drive technology. The Company's second product line,
TapeXpress, consists of 18 and 36-track products based on the IBM
3480/3490/3490E technologies. In addition, under its TapePro product line, the
Company produces 9-track reel-to-reel tape drives which are used exclusively for
data interchange. The Company also distributes a line of DLT products
manufactured by Quantum and markets other items, including controller cards
which connect its TapePro and TapeXpress products to personal computers,
interchange software, storage management software supplied by third parties,
spare parts and tape media.
 
    The Company was formed in 1980 and thereafter, through a series of
financings and two acquisitions, the Company built its equity base and expanded
its manufacturing and engineering capabilities. Initially, the Company marketed
a controller card and software which enabled data interchange between personal
computers and 9-track tape drives. In 1986, the Company became a VAR and bundled
its products with 9-track tape drives manufactured by third parties. Through a
private offering of Series A Preferred Stock in May 1989, the Company raised
$1.1 million, which it used to develop and manufacture its own 9-track tape
drives. In May 1992, to expand into the 18/36-track business, the Company
acquired Mountain Engineering, Inc., an independent design team of 18-track
products, for stock valued at $133,000. In July 1992, the Company raised an
additional $1.3 million in a private offering of Series B Preferred Stock in
order to fund product development. In May 1993, the Company acquired from
Archive Corporation, a wholly owned subsidiary of Conner Peripherals, Inc.
("Conner"), in a transaction accounted for as a purchase (the "Cipher
Acquisition"), all of the engineering, manufacturing and marketing rights of
Cipher Data Products, Inc. ("Cipher") to the half-inch tape drive product lines
(the 9-track "995" product and the 18-track "T480" product) with annual revenues
of approximately $20 million. Total consideration for the Cipher Acquisition,
which was completed in October 1993 of the next fiscal year, amounted to $8.3
million, consisting of $1 million of cash borrowed under the Company's revolving
line of credit, $3.7 million under the subordinated installment note payable to
Archive Corporation (the "Archive Note"), and $3.6 million of Series C Preferred
Stock.

</TABLE>
 
THREE MONTHS ENDED SEPTEMBER 30, 1996 COMPARED TO 1995
 
    NET SALES.  The Company's net sales of $12.0 million in the first quarter of
fiscal year 1997 (the "1997 First Quarter") grew by $1.0 million or 9.1% over
net sales of $11.0 million in the first quarter of fiscal year 1996 (the "1996
First Quarter"). The sales growth was primarily attributable to new product
introductions, partially offset by declines in the dollar value of Quantum DLT
products distributed by the Company and declines in 9-track sales. In March
1996, the Company began shipments of the first base unit product in its new DLT
LibraryXpress line which contributed $1.9 million in sales to the 1997 First
Quarter. The Company expects this product and follow-on products to generate a
significant portion of its revenues in fiscal year 1997. Offsetting this
increase, however, was a $1.7 million decline in sales of DLT distributed
product from $2.5 million in the 1996 First Quarter to $819,000 in the 1997
First Quarter. This decline was the result of the fact that the Quantum DLT
products have become commodities in the marketplace and
 
                                       18
<PAGE>
are available from other suppliers at prices below those offered by the Company.
In addition, a majority of the sales of the Quantum DLT 4500/4700 loaders have
been replaced by sales of the Company's own LibraryXpress products. The Company
expects these trends to continue. The largest sales growth of $2.1 million was
reported in the Company's 36-track products for which 1997 First Quarter sales
of $3.5 million grew to 2.5 times their 1996 First Quarter level of $1.4
million, principally as a result of increased sales of the L490E, mainly to DEC,
and sales attributable to the introduction of two new 36-track products after
the 1996 First Quarter, the L60E in November 1995 and the T490E in March 1996.
The Company expects that revenues from its 36-track products will increase in
fiscal year 1997 as it commences shipments to IBM beginning in the second
quarter. Sales of 18-track products ($1.6 million) were level with the prior
year. Shipment of 18-track products had been constrained in the fourth quarter
of fiscal year 1996 by a shortage of read-write head components which was
substantially resolved during the 1997 First Quarter. Without the realization of
the delayed sales related to this shortage, 1997 First Quarter 18-track sales
would have declined in comparison to the prior year, reflecting a customer
migration to 36-track products, which trend the Company expects to continue
throughout fiscal year 1997. Sales of 9-track products of $3.1 million in the
1997 First Quarter fell by $1.5 million or 32.6% from $4.6 million in the 1996
First Quarter. The decline across most of the 9-track products reflected the
general maturity of the 9-track technology, a trend which is also expected to
continue in the foreseeable future. The Company made end-of-life announcements
during the quarter on certain of the products within the 9-track product line
with the effect of narrowing the product offerings to four by the end of the
third quarter of fiscal year 1997.
 
    GROSS PROFIT.  The Company's gross profit amounted to $4.4 million in the
1997 First Quarter, up from $3.9 million in the 1996 First Quarter and
represented gross margins of 37.0% and 35.6%, respectively. The increased
profitability resulted from higher margins on newly introduced products,
principally the LibraryXpress, and the reduction in sales of DLT distributed
product at substantially lower margins than the Company's other products.
Management does not believe that this gross margin level will be maintained.
 
    SALES AND MARKETING EXPENSES.  Sales and marketing expenses amounted to $1.8
million or 14.8% of net sales in the 1997 First Quarter compared to $1.4 million
or 13.1% of sales in 1996. The increased level of expenditures is principally
related to the Company's introduction of its new LibraryXpress product line.
 
    RESEARCH AND DEVELOPMENT EXPENSES.  Research and development expenses
amounted to $1.1 million or 9.3% of net sales in the 1997 First Quarter, up
slightly from $1.0 million or 8.9% of net sales in 1996. During fiscal year
1996, development efforts were focused on the new LibraryXpress base unit. In
fiscal year 1997, the focus was shifted to the follow-on products in the
LibraryXpress line and to refinements of the 36-track products to be shipped to
IBM beginning in the second quarter. Expenses were also incurred in the first
quarters of both fiscal years 1996 and 1997 relating to the development of a
completely new tape recording technology which will be the basis for a new
product line. The Company intends to continue this development in fiscal year
1997 and spend 7% to 8% of net sales on research and development during such
year.
 
    GENERAL AND ADMINISTRATIVE EXPENSES.  General and administrative expenses
amounted to $951,000 or 7.9% of net sales in the 1997 First Quarter, up from
$750,000 or 6.8% of sales in the 1996 First Quarter. The higher level of
expenses in 1997 was related to an increase in support personnel, including a
strengthening of the Company's data processing department, as well as higher
levels of consulting fees and computer related expenses.
 
    INTEREST EXPENSE.  Net interest expense amounted to $57,000 in the 1997
First Quarter and was comprised principally of interest related to borrowings
under the Company's revolving bank line of credit. Average borrowings during the
quarter amounted to $2.3 million. In the 1996 First Quarter, net interest
expense amounted to $31,000 consisting of $16,000 of interest expense related to
$760,000 of average bank
 
                                       19
<PAGE>
borrowings and $15,000 related to the final installment of the Archive Note. The
Archive Note was repaid in full in November 1995.
 
    INCOME TAXES.  The Company's provision for state and federal income taxes in
the 1997 First Quarter amounted to $217,000 or an effective tax rate of 40%,
which the Company believes to be representative of its normalized effective tax
rate. In the 1996 First Quarter, the tax provision amounted to $272,000 or an
effective tax rate of 37%.
 
FISCAL YEAR 1996 COMPARED TO 1995
 
    NET SALES.  The Company's net sales of $47.2 million in fiscal year 1996
grew by $9.0 million or 23.6% over net sales of $38.2 million in fiscal year
1995. This sales growth was driven by new product introductions which more than
offset declines in both 18-track and 9-track sales. In particular, the first
shipments of the LXB, the base unit product in the Company's new LibraryXpress
product line, were made in March 1996. Shipments of the LXB during the last four
months of fiscal year 1996 generated $1.2 million in sales. An additional $3.4
million in fiscal year 1996 growth was generated from a 50.0% increase in sales
of DLT distributed products, including the DLT 4500/4700 loaders which were
introduced during the year by Quantum. The largest portion of sales growth, $7.0
million, was reported in the Company's 36-track products, with fiscal year 1996
sales of $9.3 million growing to four times its fiscal year 1995 level of $2.3
million. This growth was the result of (i) strong sales of the inaugural
36-track product, the L490E, which was introduced midway through fiscal year
1995, and (ii) two new 36-track product introductions, the 60-cartridge L60E,
which began shipping in November 1995, and the single cartridge T490E, which
began shipping in March 1996. In the 18-track product line, sales declined by
6.8% in fiscal year 1996, reflecting the market's general migration to 36-track
products. Sales of 9-track products of $14.4 million in fiscal year 1996
declined by $4.2 million or 22.6% from $18.6 million in fiscal year 1995,
reflecting the general maturity of the 9-track technology. Finally, fiscal year
1996 sales of controllers, spare parts, software and other products amounted to
$4.9 million, an increase of 81.5% over the fiscal year 1995 level of $2.7
million. This growth was attributable to increased sales of spare parts and tape
media, mainly DLT tape.
 
    GROSS PROFIT.  The Company's gross profit amounted to $16.1 million in
fiscal year 1996, up from $11.1 million in fiscal year 1995, and represented
gross margins of 34.1% and 29.1%, respectively. The increased profitability
resulted from higher margins on newly introduced products, and improved margins
on DLT distributed product because more product was sold through the VAR and
European channels compared to a concentration in the distributor channel in the
prior year. In addition, fiscal year 1996 gross margins were significantly
improved on 18-track products as material cost savings were realized from an
investment in re-engineering certain electrical components.
 
    SALES AND MARKETING EXPENSES.  Sales and marketing expenses amounted to $5.9
million or 12.6% of net sales in fiscal year 1996 compared to $4.9 million or
12.8% of sales in 1995. This increase in total expenditures resulted from costs
needed to support the higher sales level, including salaries and benefits, sales
commissions, advertising and promotion and travel and related costs. In
addition, higher costs were incurred for prototype units, advertising and
promotions related to new product introductions.
 
    RESEARCH AND DEVELOPMENT EXPENSES.  Research and development expenses
amounted to $3.7 million or 7.8% of net sales in fiscal year 1996 compared to
$3.1 million or 8.1% of net sales in 1995. The increased expenses related to the
development of the Company's two new 36-track products, the T490E and the L60E,
and to a greater extent, the development of the new LibraryXpress products. The
development of the two 36-track products required a lower level of expense than
the LibraryXpress products because they were derivative products using common
electrical components and robotics. The Company also incurred expenses in fiscal
year 1996 related to the development of a new tape recording technology and
coding scheme using the partial response maximum likelihood concept.
 
                                       20
<PAGE>
    GENERAL AND ADMINISTRATIVE EXPENSES.  General and administrative expenses
amounted to $2.9 million or 6.2% of net sales in fiscal year 1996 compared to
$2.2 million or 5.7% of net sales in 1995. The higher level of expenses in 1996
included legal fees related to the filing of a number of patent applications,
increased bad debt reserves related to the higher level of sales and increased
facility costs and computer related expenses.
 
    INTEREST EXPENSE.  Net interest expense amounted to $154,000 in fiscal year
1996 and included $124,000 of interest expense related to borrowings under the
Company's revolving bank line of credit and $30,000 of interest expense related
to the final installment of the Archive Note which was repaid in full in
November 1995. Average borrowings under the Company's bank line of credit in
fiscal year 1996 amounted to $1.4 million. In fiscal year 1995, net interest
expense amounted to $204,000 consisting of $214,000 of interest expense and
$10,000 of interest income. The portion of the interest expense relating to the
Archive Note amounted to $145,000 and the remaining $69,000 of interest expense
related to borrowings under the Company's revolving bank line of credit, which
borrowings averaged $725,000 in fiscal year 1995.
 
    INCOME TAXES.  The Company's fiscal year 1996 provision for state and
federal income taxes amounted to $254,000 or an effective tax rate of 7.4%. In
fiscal year 1995, the tax provision amounted to $269,000 resulting in a more
normalized effective tax rate of 35%. The low tax rate in 1996 was the result of
the release of a deferred tax valuation allowance of $997,000 in the fourth
fiscal quarter. As discussed in Note 5 to the Consolidated Financial Statements,
in prior years the Company established the reserve in accordance with SFAS No.
109, "Accounting for Income Taxes," which requires that a valuation allowance be
recorded "when it is more likely than not" that any portion of a deferred tax
asset will not be realized. The reserve had been established to reduce the net
deferred tax asset to a minimal amount, because of the Company's past history of
operating losses and marginal profitability and due to the inherent uncertainty
in forecasts of future events and operating results. However, in the fourth
quarter of fiscal year 1996, due to the significant profitability in that
quarter and based on management's expectations of future results, the Company
determined that it was more likely than not that deferred tax assets would be
realized through future taxable earnings or alternative tax strategies. As a
result, the valuation allowance was reduced to zero in that quarter.
 
FISCAL YEAR 1995 COMPARED TO 1994
 
    NET SALES.  The Company's net sales of $38.2 million in fiscal year 1995
grew by $4.2 million or 12.4% over net sales of $34.0 million in fiscal year
1994. Sales growth in DLT distributed products and in 36 and 18-track products
more than offset a decline in 9-track sales. The Company began distributing DLT
products in December 1993, midway through fiscal year 1994. Sales of DLT
products grew rapidly in the succeeding year and rose from $723,000 in fiscal
year 1994 to $6.8 million in fiscal year 1995. In December 1994, the Company
introduced the L490E, its first 36-track product. Shipments of this new product
during the remainder of fiscal year 1995 amounted to $2.3 million. In the
18-track product line, sales of $7.7 million in fiscal year 1995 grew by $2.4
million or 45.3% over net sales of $5.3 million in fiscal year 1994. This growth
was also the result of new product introductions, including the T490 single
cartridge 18-track product developed for DEC, which began shipping in April
1994, and the L490, the Company's 10-cartridge 18-track product which began
shipping in December 1994. Sales of 9-track products of $18.6 million in fiscal
year 1995 fell by $6.8 million or 26.8% from $25.4 million in fiscal year 1994,
despite the addition of $13.8 million in 9-track sales in fiscal year 1994 from
the acquisition of the 995 product.
 
    GROSS PROFIT.  The Company's gross profit amounted to $11.1 million in both
fiscal year 1995 and 1994, while the gross margin declined to 29.1% in 1995
compared to 32.8% in 1994. The largest factor contributing to the decline was
the increase in sales of DLT distributed product through distributor and VAR
channels at relatively low margins. Typical of distributor margins, sales of DLT
products through the distributor and VAR channels were made at 23% margins in
1994 and 21% margins in 1995. The application of these lower margins to DLT
revenues which grew from $723,000 in fiscal year 1994 to
 
                                       21
<PAGE>
$6.8 million in fiscal year 1995 caused the reduction in overall gross margins.
The reduction in the concentration of OEM sales and the increase in
international sales partially offset this decline.
 
    SALES AND MARKETING EXPENSES.  Sales and marketing expenses amounted to $4.9
million or 12.8% of net sales in fiscal year 1995 compared to $4.7 million or
13.9% of net sales in 1994. Such expenses did not grow proportionately to sales
in fiscal year 1995, because fiscal year 1994 included a relatively higher level
of spending for advertising and promotions pertaining to new product
introductions.
 
    RESEARCH AND DEVELOPMENT EXPENSES.  Research and development expenses
amounted to $3.1 million or 8.1% of net sales in fiscal year 1995, down from
$3.4 million or 10.0% of net sales in 1994. The higher level of spending in 1994
related to the concurrent development of three new products (T490, L490 and
L490E), and the merging of the Overland and Cipher technologies, which included
the development of a common electrical and firmware set and investment in
tooling, ASIC development and other non-recurring expenditures.
 
    GENERAL AND ADMINISTRATIVE EXPENSES.  General and administrative expenses
amounted to $2.2 million or 5.7% of net sales in fiscal year 1995, down from
$2.4 million or 7.1% of net sales in 1994. The level of expenses in fiscal year
1994 were higher because they included certain costs relating to the relocation
of the Company's headquarters and manufacturing facilities.
 
    INTEREST EXPENSE.  Net interest expense amounted to $204,000 in fiscal year
1995 and consisted of $145,000 of interest expense relating to the Archive Note,
$69,000 of interest expense related to borrowings under the Company's revolving
bank line of credit and $10,000 of interest income. In fiscal year 1994, net
interest expense of $214,000 consisted of $248,000 of interest expense related
principally to the Archive Note and $34,000 of interest income.
 
    INCOME TAXES.  The Company's fiscal year 1995 provision for state and
federal income taxes amounted to $269,000 or an effective tax rate of 35%. In
fiscal year 1994, the tax provision amounted to $219,000 resulting in an
effective tax rate of 62%. The higher tax rate in 1994 resulted from the
increase in the deferred tax valuation allowance, offset partially by research
and development tax credits.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    During fiscal year 1996, the Company generated $841,000 of cash from
operating activities, received $565,000 from the sale and issuance of Common
Stock to the Company's employees and borrowed an additional $100,000 against the
Company's bank line of credit. The Company also spent $841,000 on capital
expenditures and made the final installment payment on the Archive Note. These
activities caused a decrease in the Company's cash balance of $82,000 to a
year-end balance of $19,000.
 
    The Company's working capital increased to $10.3 million at June 30, 1996,
up from $6.4 million at June 30, 1995. The increased working capital was needed
to support the accelerated revenue rate and consisted of higher receivable
balances, which grew from $6.3 million in 1995 to $7.2 million in 1996, and
higher inventory balances, which grew from $5.4 million to $8.4 million during
the same period. Deferred tax assets also rose by $1.2 million in 1996.
Offsetting these increases was a higher balance of accounts payable and accrued
liabilities/compensation totaling $2.3 million. The Company's working capital
increased further to $12.4 million at September 30, 1996.
 
    The Company has a bank line of credit of up to $5 million based upon
eligible accounts receivable, with interest on borrowed funds at prime plus
0.5%. See Note 4 of Notes to the Consolidated Financial Statements. The bank
line of credit is collateralized by substantially all of the Company's assets
and expires in November 1998. The credit agreement prohibits the payment of
dividends without prior approval of the lender and requires the Company to
maintain certain covenants and financial ratios including working capital and
net worth ratios, all of which the Company has satisfied for the periods
presented. As of September 30, 1996, the Company had outstanding borrowings
thereunder of $3.3 million and had
 
                                       22
<PAGE>
additional borrowing capacity of $1.1 million. The Company is currently
negotiating and has received a preliminary commitment for additional bank
financing of up to $3 million in the form of a term loan which would be
available to finance capital expenditures.
 
    The Company currently expects to make capital expenditures of approximately
$3 million during fiscal year 1997. There were no significant capital
commitments, however, as of September 30, 1996. The Company believes that the
net proceeds from this Offering, the funds expected to be generated from
operations, its bank line of credit and the pending capital expenditure line,
will provide sufficient cash to fund its working capital needs and planned
capital expenditures for the foreseeable future. See "Use of Proceeds."
 
INFLATION
 
    Inflation has not had a significant negative impact on the Company's
operations during the periods presented. With the exception of its OEM
contracts, which contain fixed pricing for up to one year, the Company has
historically been able to pass on to its customers increases in raw material
prices caused by inflation. There can be no assurance, however, that the Company
will be able to continue to pass on any future increases should they occur.
Although the Company's exposure to the effects of inflation will be magnified by
the expected increase in OEM business, the Company believes that its continuous
efforts at material and labor cost reductions will minimize such effects.

</TABLE>
 
    Revenues in the Company's third quarter ended March 31, 1996 of $10.9
million declined by $1.4 million or 11.4% from the sales in the previous quarter
of $12.3 million. During this quarter, the Company, as well as many of its
competitors, experienced a general slow-down in the marketplace. In addition,
the Company's sales of Quantum DLT drives which the Company distributes were
limited by a supply shortage of these drives which also delayed introduction of
the Company's new LXB product.
 
                                       23
<PAGE>
    Revenues in the Company's 1997 First Quarter of $12.0 million declined by
$1.0 million or 7.7% from the sales in the previous quarter of $13.0 million.
The reduction in sales was caused by a supply constraint with the read-write
heads for its 18-track products and a decrease in sales of distributed Quantum
DLT products in light of increased price competition. Income from operations was
also reduced in the 1997 First Quarter because of higher advertising and
promotional spending related to new product introductions and a higher level of
research and development spending for product enhancements. An alternate
supplier was subsequently qualified for the 18-track heads.
 
    The Company's results can fluctuate substantially from time to time for
various reasons. All of the markets served by the Company are volatile and
subject to market shifts, which may or may not be discernible in advance by the
Company. A slowdown in the demand for workstations, mid-range computer systems
and networks could have a significant adverse effect on the demand for the
Company's products in any given period. The Company has experienced delays in
receipt of purchase orders and, on occasion, anticipated purchase orders have
been rescheduled or have not materialized due to changes in customer
requirements. The Company's customers may cancel or delay purchase orders for a
variety of reasons, including the rescheduling of new product introductions,
changes in their inventory practices or forecasted demand, general economic
conditions affecting the computer market, changes in pricing by the Company and
its competitors, new product announcements by the Company or others, quality or
reliability problems related to the Company's products, or selection of
competitive products as alternate sources of supply. In addition, because a
large portion of the Company's sales are generated by its European distributor
channel (20% in fiscal year 1996), the first fiscal quarter (July through
September) is impacted by seasonally slow European orders, reflecting the summer
holiday period in Europe. The Company's operations may reflect substantial
fluctuations from period to period as a consequence of such industry shifts,
price erosion, general economic conditions affecting the timing of orders from
customers, as well as other factors discussed herein. In particular, the
Company's ability to forecast sales to distributors and VARs and, increasingly
to OEMs, is especially limited as such customers typically provide the Company
with relatively short order lead times or are permitted to change orders on
short notice, respectively. A portion of the Company's expenses are fixed and
difficult to reduce should revenues not meet the Company's expectations, thus
magnifying the material adverse effect of any revenue shortfall. The Company's
gross profit has fluctuated and will continue to fluctuate quarterly and
annually based upon a variety of factors such as the level of utilization of the
Company's production capacity, changes in product mix, average selling prices,
demand or manufacturing yields, increases in production and engineering costs
associated with initial production of new programs, changes in the cost of or
limitations on availability of materials and labor shortages. During the first
quarter of fiscal year 1997, the Company reported a gross margin of 37% which
was higher than its average quarterly gross margin during fiscal years 1994,
1995 and 1996. Management does not believe that this gross margin level, which
was positively affected by an increase in the sales of the LibraryXpress and a
decrease in sales of distributed product, will be maintained. Generally, new
products have higher gross margins than more mature products. Therefore, the
Company's ability to introduce new products in a timely fashion is an important
factor to its profitability. Based upon all of the foregoing, the Company
believes that period-to-period comparisons of its revenues and operating results
will continue to fluctuate and are not necessarily meaningful and should not be
relied on as indications of future performance. Furthermore, in some future
quarter the Company's revenues and operating results could be below the
expectations of public market analysts or investors, which could result in a
material adverse effect on the price of the Common Stock.

COMPANY
 
    Overland designs, develops, manufactures, markets and supports magnetic tape
data storage systems used by businesses for backup, archival and data
interchange functions. The Company primarily offers three product
lines--LibraryXpress, TapeXpress and TapePro--which are designed to meet the
data storage needs of client/server networks, workstations, minicomputers and
personal computers. Overland believes that it is well positioned to take
advantage of the rapidly increasing demand for storage capacity, particularly
that created by the growth in client/server networks. To address this growing
network storage demand, Overland introduced the LXB in March 1996, the first
product of its LibraryXpress line of automated tape libraries. In August 1996,
BYTE Magazine selected the LXB as the "Best Overall DLT Tape Library." The
Company believes that, with the anticipated delivery of the LXG control unit
during the first quarter of calendar year 1997, LibraryXpress will constitute
the first automated tape library in its capacity class that is truly "scalable,"
in that it is designed to allow end-users to configure specific combinations of
drives and cartridges as their storage requirements change without having to
replace their existing Overland units. Management believes that LibraryXpress
has significant market potential because it is designed to enable companies to
increase their storage capacity in a cost effective manner as their businesses
grow.
 
    The Company's TapeXpress product line consists of 18/36-track tape drives
and loaders based on an IBM standard and, in October 1996, IBM selected the
Company to be a supplier of 36-track products. With its TapePro product line,
Overland is a leading supplier of 9-track reel-to-reel products used in data
interchange. In addition, the Company distributes a line of DLT-based products
manufactured by Quantum and markets various other products, including controller
cards which connect its tape drives to personal computers, interchange software
developed by the Company, storage management software supplied by third parties,

HISTORY
 
    Overland was formed in 1980 and became a VAR in 1986, when it began
providing customers with a total data storage solution by bundling its
controller cards and software with third party 9-track tape drives. In 1991, the
Company recruited professional senior management and expanded its manufacturing
and development operations. Since that time, Overland has experienced rapid
growth, with revenue and operating income increasing at compound annual growth
rates of 43% and 207%, respectively. The Company's most significant source of
growth occurred in 1993 when it acquired certain Cipher 9-track and 18-track
product lines from Archive Corporation, a wholly owned subsidiary of Conner,
with annual revenues of approximately $20 million.
 
    Throughout its history, the Company has designed and developed innovative
product offerings beginning with (i) the first controller card to allow personal
computers to connect to 9-track tape drives, thereby facilitating data
interchange between personal computers and mainframes or minicomputers, and
 
                                       25
<PAGE>
(ii) DataTools, a specialized software package which facilitates data
interchange. In 1989, the Company began developing TapePro, the first truly
desktop-based 9-track tape drive. Overland's internal development efforts and
its acquisition of the Cipher product lines led to the introduction of its 18
and 36-track product lines. In March 1996, the Company commenced shipment of the
LXB, the first product in the LibraryXpress product line.
 
INDUSTRY OVERVIEW
 
    The data storage industry has experienced rapid growth in recent years in
response to the significant increase in the amount of electronically stored
data. Overland believes that this growth will continue due to (i) the
introduction of increasingly powerful computing platforms, (ii) the spreading
use of computers for tasks that previously were performed manually, (iii) the
increasing number, size, bandwidth and complexity of computer networks,
particularly client/server networks, (iv) the rapid growth of data-intensive
applications and (v) the growth of intranet and Internet based computing. In
addition, emerging data-intensive applications, such as still image, motion
video, check imaging, and other multimedia and character recognition uses, are
accelerating the demand for data storage solutions.
 
    Corporations, governments and other large enterprises increasingly are
recognizing the critical nature and strategic importance of stored data and the
need to safely backup and efficiently manage that data. These enterprises are
demanding data storage solutions which provide fast and reliable storage and
retrieval capabilities for rapidly increasing amounts of data. In addition,
business managers are increasingly perceiving data to be critical at a
company-wide level as opposed to only being important at the individual
workstation level. As a result, central management of data has increased both in
distributed and centralized client/server environments. Centralization of
storage has also become more desirable because of cost factors.
 
    The Company believes that the factors noted above will greatly increase the
number of sites worldwide requiring large amounts of backup and, therefore, the
need for advanced storage solutions. According to the Strategic Research Corp.,
a storage management industry consultant, the number of centralized storage
sites worldwide requiring more than 200GB backup is projected to grow from
approximately 116,000 sites in 1996 to 660,000 sites by the year 2000.
 
    Current data storage solutions provide secure, high capacity data
repositories based primarily on three technologies--magnetic tape, magnetic disk
and optical disk. Magnetic tape remains the most cost-effective storage medium
(at approximately one-fifth of the cost per megabyte stored as compared to
magnetic and optical disk), and is used most often for backup and archival
functions. Magnetic disk and optical disk provide relatively quick access to
stored data and are generally used for online and immediately offline storage
functions. Utilization of magnetic tape for backup, archive and data interchange
historically has required a high degree of human intervention, the cost of which
is reduced in a centralized storage environment, particularly those that utilize
automated tape storage systems. In addition, as the amount of data has grown,
the backup "window," or amount of time allocated to backup, has continued to
decrease, which has heightened demand for greater backup performance as
companies require less downtime from their computer systems. Consequently, tape
libraries have been developed which provide multiple drives in order to increase
throughput, multiple cartridges in order to increase data capacity and the
capability to function unattended in both backup and restore modes. According to
Strategic Research Corp., the quantity of tape libraries sold worldwide will
grow from an estimated 32,000 units in 1996 to 94,700 units in the year 2000.
 
    The Company believes that market demand is growing especially for expandable
or "scalable" tape libraries because managers increasingly face difficulties in
predicting their needs for data storage and backup. Scalability allows the
end-user to satisfy its current data storage requirements and protect its
original investment when faced with handling future growth, because scalability
permits the end-user to
 
                                       26
<PAGE>
buy only the storage equipment that is presently needed. Scalability then allows
the end-user to add to this configuration in a manner that incorporates and
fully utilizes the previously purchased equipment.
 
COMPANY STRATEGY
 
    Overland intends to continue building a leadership position in the magnetic
tape segment of the data storage industry. The Company believes that it
possesses certain core competencies which will help it attain this leadership
position, including: (i) advanced knowledge of hardware/software integration and
connectivity, due to its experience in designing and developing both tape drives
and libraries; (ii) experience in the magnetic tape industry, particularly with
respect to innovative mechanical, electrical and firmware designs; (iii)
comprehensive understanding of, and close contact with, end-user needs; and (iv)
experienced management and developed management processes in each functional
area of its business operations. The Company intends to leverage these core
competencies in the execution of its business strategy, which includes the
following elements:
 
    - EMPHASIZE DEVELOPMENT OF ADVANCED STORAGE SOLUTIONS.  Overland invests
      extensively in research and development in order to deliver technologies
      for the "next generation" of magnetic tape drives and automated tape
      libraries. The Company intends to continue its research and development
      efforts in areas that build upon its manufacturing, engineering and
      operational strengths in order to offer products which serve emerging data
      storage needs.
 
    - MAINTAIN LEADERSHIP IN PRODUCT RELIABILITY.  The Company believes that
      product dependability is crucial, given the critical nature of its
      customers' information and the frequent operation of backup systems during
      hours when few personnel are available to address problems. Overland
      believes that it has achieved a reputation for reliability and intends to
      continue to develop and offer high quality and reliable products. The
      Company augments this product reliability by providing comprehensive
      technical support to its customers, including online technical assistance
      and engineering support for more complex applications.
 
    - LEVERAGE CLOSE RELATIONSHIPS WITH END-USERS.  The Company believes that
      its interaction with end-users enables it to better understand the
      evolving product and application needs of its customers. Overland intends
      to continue its close contact with end-users by selling its products
      directly to them, by involving them in ongoing market research activities
      regarding future products, and by responding to their technical support
      requirements.
 
    - FURTHER DEVELOP WORLDWIDE DISTRIBUTION.  The Company believes that the
      range of data storage solutions provided by its three primary product
      lines offers significant international sales opportunities. Overland
      intends to increase the number of distributors in its existing
      international markets, develop additional distribution channels in these
      markets for new product introductions and establish appropriate
      distribution channels for its current and future products in new
      international markets.
 
    - HARVEST LEGACY MARKETS.  The markets served by the Company's 9-track and
      18-track product lines are characterized by mature technologies and large
      installed customer bases. Overland intends to capitalize on its position
      in these markets in order to capture additional market share and expects
      to realize improved operating margins as such products require limited
      research and development support as compared to newer technology.
 
    - PURSUE ALLIANCES OR ACQUISITIONS.  Overland believes that it may be able
      to expand and increase the value-added component of its product offerings
      through alliances with, or acquisitions of, complementary businesses. The
      Company intends to evaluate strategic product and technology acquisitions
      and may pursue second source manufacturing arrangements to further
      capitalize upon its engineering, manufacturing and quality process
      capabilities.

PRODUCTS
 
    The Company produces tape drives, tape loaders and automated tape libraries
based on removable tape technologies. A tape drive is a device used to read or
write data to a single magnetic tape cartridge or reel on multiple tracks of the
tape. A tape loader includes a single tape drive and contains multiple tape
cartridges which can be randomly accessed, thus permitting unattended backup of
larger data sets. The backup and restore process of a tape loader can also be
handled randomly in order to write or read a specific data file to or from a
given cartridge. A tape library is a tape loader with multiple drives. Both tape
loaders and tape libraries house tape cartridges and utilize an
electro-mechanical robotic mechanism to manipulate the tape cartridges, loading
and unloading specific tape cartridges into and out of the tape drive or drives
as directed by the storage management software.
 
    The Company currently provides turnkey data storage solutions to its
customers in distinct markets through three product lines that utilize three
generations of half-inch magnetic tape technologies. The network backup market
is served by LibraryXpress, the Company's DLT-based automated tape library
product line, which provides automated backup as companies migrate to
enterprise-wide client/server networks. The mid-range data interchange and
backup market is served by TapeXpress, the Company's 18/36-track product line.
The desktop data interchange market is served by TapePro, the Company's 9-track
product line, which targets personal computer and workstation users who need
access to data created on legacy systems.
 
    The LibraryXpress product line combines electro-mechanical robotics,
electronic hardware and firmware developed by the Company, with industry
standard tape drives supplied by Quantum, into a desktop or rack-mount
configuration. Overland's standalone tape drives and loaders also incorporate
designs of electro-mechanical robotics, electronic hardware and firmware
developed by the Company. When operated in conjunction with storage management
and interchange software, the Company's products provide a wide range of data
storage solutions for client/server networks, personal computers, workstations
and mid-range computers.
 
    Each of the Company's products is installed on specific computer platforms
with the appropriate backup, data interchange or storage management software.
Overland actively works with a number of backup and storage management software
companies to confirm that its products are properly supported. Currently, more
than 40 different software packages support the Company's products. For example,
on the Novell Netware and Microsoft Windows NT platforms, the software packages
include products from Cheyenne Software, Seagate Software, Inc. (Arcada and
Palindrome), Legato Systems Incorporated ("Legato Systems"), and STAC Inc. On
UNIX platforms, the software packages include products from Legato Systems, IBM,
Cheyenne Software and Peripheral Device Corporation.

    The end-user list price for the Company's products range from $4,400 for a
TapePro 3210 to $29,950 for the TapeXpress L60E. The LibraryXpress products can
be purchased in lower cost configurations based on the desired type and number
of DLT drives, and can also be modularly stacked in higher cost configurations
based on a customer's growing needs. Overland's three product lines are
described below in more detail.
 
    LIBRARYXPRESS PRODUCTS.  The LibraryXpress product line of automated tape
libraries is based on DLT technology, which was developed in the 1980's as a DEC
system component. In 1994, Quantum purchased the DLT technology and marketed it
as a multi-platform network backup solution. Today, DLT is becoming a common
tape backup technology for computer network systems, due to its high tape
cartridge capacity, high performance and low cost of storage. In addition, DLT
cartridges are well suited for robotic movement, which facilitates the
development of loaders and libraries.
 
    In March 1996, the Company commenced shipment of the LXB automated tape
library base unit, which consists of one or two DLT drives and a ten-cartridge
removable magazine. The Company currently offers the LXB with Quantum's 2000XT
and 4000 DLT tape drives and it expects to offer the LXB with Quantum's new 7000
DLT tape drive in January 1997. During the first quarter of calendar year 1997,
the Company intends to commence shipment of (i) the LXG control unit which will
provide library control from a single point and the ability to modularly stack
up to eight LXB or LXC capacity modules, and
 
                                       29
<PAGE>
(ii) the LXC capacity module which will consist of 16 cartridges and no drives.
The LXG will allow users to pass cartridges from module to module as one
integrated unit, providing true scalability and allowing end-users to expand
their storage capacity to meet their growing business needs while protecting
their original investment in the LXB. The Company shipped prototype units of the
LXG in November 1996.
 
    In August 1996, BYTE Magazine selected the LXB as the "Best Overall DLT Tape
Library." The Company believes that, with the anticipated delivery of the
related LXG control unit during the first quarter of calendar year 1997,
LibraryXpress will constitute the first automated tape library in its capacity
class that is truly "scalable," in that it is designed to allow end-users to
configure combinations of drives and cartridges as their storage requirements
change without having to replace their existing Overland units. Management
believes that LibraryXpress has significant market potential because it is
designed to enable companies to increase their storage capacity in a cost
effective manner as their businesses grow.
 
    TAPEXPRESS (18/36-TRACK) PRODUCTS.  The TapeXpress product line of
18/36-track drives and loaders is based on IBM's 3480/3490/3490E technologies.
The 3480 technology was introduced in 1984 to replace 9-track tape for backup,
archival and data interchange functions. In response to the need for more
capacity per cartridge, the 3490 and 3490E technologies subsequently were
introduced. The installed base of 3480 and 3490 drives and cartridges is very
large and their primary function currently is for data interchange. Based on the
size of this installed base and the mature nature of this technology, the
Company considers its 18-track products to be legacy products. The Company's
T490E, L490E and L60E products are compatible with the 36-track IBM 3490E format
and are the only products in the marketplace that are capable of reading and
writing in both 18 and 36-track formats. Overland's products connect easily to
numerous hardware platforms and are supported by many popular backup and
hierarchical storage management ("HSM") software packages. IBM recently selected
the Company to be a supplier of 36-track products.
 
    TAPEPRO (9-TRACK) PRODUCTS.  The TapePro product line consists of compact,
lightweight and low-cost desktop tape drives, and a legacy tape drive sold
primarily to DEC for replacement purposes. Nine-track tape once was the only
tape technology used for archive, backup and data interchange functions. Today,
9-track tape is used only for data interchange, a limited function used to
access data that generally was stored when 9-track was the only tape technology.
Data interchange continues to be important for end-users who need to access data
on the estimated 250 million 9-track reels worldwide. Although new information
currently is not stored on 9-track tape, end-users need to access information
stored on these tapes periodically and it generally is not cost-efficient to
transfer this information to another storage medium. The Company has not
recently, and will not in the future, invest additional research and development
resources in the 9-track product line.
 
SALES AND MARKETING
 
SALES
 
    The Company sells its products domestically through four channels: (i) OEM,
(ii) volume, consisting of system integrators, technical distributors and VARs,
(iii) resellers, and (iv) end-users. Overland also sells its products
internationally, and is experiencing strong growth in the European market. The
Company believes that, in fiscal year 1997, its new LibraryXpress products will
be sold principally through its volume and international channels. In fiscal
1997, the Company expects that a significant portion of its 9-track, 18-track
and 36-track products will be sold through the OEM channel principally to IBM
and DEC. Regardless of the channel through which they are sold, all of
Overland's products are designed and manufactured to meet OEM level requirements
and reliability standards. Because the OEM qualification process can take six to
18 months to complete, the Company's initial sales of new products are often
made to other volume and reseller customers and end-users, which typically
evaluate, integrate and adopt new technologies and products more quickly. After
qualification and acceptance, OEM sales generally represent an increasing
proportion of a product's unit sales and are important to the Company in terms
of
 
                                       30

validating its products in the marketplace and achieving desirable production
volume. The table below sets forth the distribution of the Company's net sales

</TABLE>
 
    OEM CHANNEL.  The Company currently has supply agreements with Bull S.A.,
DEC, IBM, Intergraph Corporation, NCR Corporation and Symbios Logic, Inc., each
of which incorporates Overland's products into their system offerings. Overland
often works with its OEM customers early in a new product development cycle in
order to design its products to meet their specifications. The OEM sales cycle
is often lengthy and typically consists of a general technology evaluation,
qualification of product specifications, verification of product performance
against these specifications, integration testing of the product within the
customers' systems, product announcement and volume shipment. As is typical in
the industry, the Company's OEM contracts provide for annual price reviews and
the customers are not required to purchase minimum quantities. DEC has been the
Company's largest customer, accounting for approximately 36%, 21% and 23% of
sales in fiscal years 1994, 1995 and 1996, respectively. Although no other
customer accounted for ten percent (10%) or more of sales for any year during
the three-year period ended June 30, 1996, the Company anticipates that IBM will
account for over 10% of sales in fiscal year 1997. The Company supports this
channel through a field sales office and other field representatives.
 
    VOLUME CHANNEL.  The Company's volume channel includes systems integrators,
technical distributors and VARs, each of which sells to both resellers and
end-users. Certain of the Company's volume channel customers specialize in the
insurance, banking, financial, geophysical and medical industries, and offer a
variety of value-added services relating to the Company's products. For example,
Overland's products frequently are packaged by these customers as part of a
complete data processing system or combined with other storage devices, such as
redundant array of independent disks ("RAID") systems, to deliver a complete
storage subsystem. These customers also recommend the Company's products as
replacement solutions when backup systems are upgraded, and are bundled with
storage management software specific to the end-user's system. The Company
supports this channel through a field sales office and other field
representatives.
 
    RESELLER AND END-USER CHANNELS.  The Company regards sales to the reseller
and end-user channels as an important part of its strategy. The Company believes
that direct sales and contact with end-users and the resellers which sell to
them, provide the Company with important information about the performance of
its products on various platforms and with various software applications.
Consequently, the Company intends to maintain internal capabilities to serve
end-user customers when its other channel partners are unable to do so, even
though the end-user channel as a percentage of sales is decreasing. The Company
supports this channel through its in-house sales force.
 
    INTERNATIONAL CHANNELS.  The Company's international sales have shown strong
growth during the last three years, and the Company believes that its three
product lines offer additional international sales opportunities. Accordingly,
Overland intends to increase the number of distributors in its existing
international markets, develop additional distribution channels in these markets
for new product introductions
 
                                       31
<PAGE>
and establish appropriate distribution channels for its current and future
products in new international markets. Overland currently sells its products
overseas primarily to technical distributors and VARs, and has recently
developed a new OEM relationship in Europe. Although all sales are currently
denominated in U.S. dollars, the Company may bill its international customers in
other currencies in the near future. The Company assigns to its international
distributors the right to sell Overland's products in a country or group of
countries. These distributors then sell the Company's products to systems
integrators, VARs and end-users. In addition, many domestic customers ship a
portion of the Company's products to their overseas customers. The Company has
established a wholly-owned subsidiary in the United Kingdom to provide sales and
technical support to the European market and intends to provide product repair
and manufacturing integration services for certain products at the same site.
Sales personnel are located in various cities throughout Europe, while sales
personnel located in the Company's corporate offices serve the Pacific Rim,
South America, Australia, New Zealand and Mexico.
 
MARKETING
 
    Overland supports its sales efforts with various marketing programs designed
to build the Company's brand name and attract new customers. Its channel
partners are provided with a full range of marketing materials, including
product specification literature, software connectivity information and
application notes. The Company's management and engineering personnel work with
the channel partners to provide support and, in certain instances, visit
potential customer sites to explain and demonstrate the technical advantages of
the Company's products. In addition, the Company holds two conferences each year
to inform its channel partners of new product developments and programs and to
discuss emerging trends in their markets. The Company also maintains press
relations both domestically and in Europe, advertises in computer systems
publications targeted to its channels and offers market development funds to all
of its channel partners except for OEM customers and end-users.
 
    The Company participates in national and regional trade shows both
domestically and internationally and displays its products at the CEBIT show in
Europe and domestically at COMDEX, NetWorld/InterOp and AIIM. The Company also
maintains a World Wide Web site (http://www.overlanddata.com), which features
comprehensive marketing information, includes news releases and product
specifications, and has a computer BBS from which customers can download
application, service and technical support notes. In the future, the Company
intends to expand its Web site to incorporate its BBS information, provide
information on and links to its channel partners and to develop Internet
commerce capabilities which will be linked to the Company's other
enterprise-wide systems. Information contained in the Company's World Wide Web
site shall not be deemed to be a part of this Prospectus.
 
CUSTOMER SERVICE AND SUPPORT
 
    The Company believes that strong customer service and support is essential
to maintain its leadership in product reliability. Sales support personnel
ensure that customer orders are filled on a timely basis, delivery problems are
resolved quickly and warranty returns are promptly authorized. Overland's
technical support personnel, located both in its headquarters facility and its
U.K. office, are trained with respect to the Company's products and assist
customers with "plug-and-play" compatibility between multiple hardware
platforms, operating systems and backup, data interchange and storage management
software. The Company's application engineers are available to solve more
complex customer problems and visit customer sites when necessary. Customers
that need service and support can contact the Company through its toll-free
telephone lines, facsimile and Internet e-mail.
 
    The Company's standard warranty is a two-year return-to-factory policy which
covers both parts and labor. For products that it distributes and for drives and
tapes used in the Company's products that are manufactured by a third party, the
Company passes on to the customer the warranty provided by the manufacturer. The
Company also offers on-site service for certain of its products, including
24-hour service, seven-days-a-week, for which it contracts with third-party
service providers.
 
                                       32
<PAGE>
COMPETITION
 
    The worldwide tape storage market is intensely competitive as a large number
of manufacturers of alternative tape technologies compete for a limited number
of customers and barriers to entry are relatively low in the library product
category. The Company believes that the significant competitive factors
affecting its business are price, performance, reliability, support and
reputation, and that it competes favorably with regard to each of these factors.
Overland currently participates in three market areas which are defined by
different tape technologies: (i) network data storage; (ii) data backup and
interchange based on IBM compatible 3480/3490/3490E technology; and (iii) data
interchange based on 9-track reel-to-reel technology. In each of these areas,
many of the Company's competitors have substantially greater financial and other
resources, larger research and development staffs, and more experience and
capabilities in manufacturing, marketing and distributing products than the
Company.
 
    For network data storage, the Company's LibraryXpress LXB product currently
competes with products made by ADIC, ATL/Odetics, Breece Hill, Hewlett-Packard,
Quantum and Storage Technology and the Company believes that additional
competitors will enter the market. The Company, and all of its current
competitors with the exception of Quantum, design and manufacturer only the
robotic portion of the library and purchase the DLT tape drives from Quantum.
Quantum purchases the robotic portion of its product from a third party.
 
    For the data backup and interchange market, which is based on IBM compatible
3480/3490/3490E technology, the Company offers a product line of 18 and 36-track
products, which the Company believes compete primarily with products made by
Fujitsu, Hitachi, Laser Magnetic Storage and Storage Technology. Unlike the
automated tape library market, there is a relatively high barrier to entry in
the IBM compatible backup and interchange market because each of the companies
has developed the entire product, both the drive and any robotic mechanisms. For
the 9-track data interchange market, the Company is currently a market leader.
The Company believes it competes with Anritsu American Incorporated,
Hewlett-Packard and M4 Data, Inc. This mature market is steadily declining, and,
similar to the 18 and 36-track market, there is a relatively high barrier to
entry.
 
RESEARCH AND DEVELOPMENT
 
    The Company believes that its ongoing success will depend upon its ability
to develop new technologies or adapt existing technologies to produce removable
storage automation products that meet the backup, archival and HSM needs of
large network users. Consequently, the Company dedicates significant resources
to its research and development ("R&D") efforts and currently employs 36 people
in its R&D department, including 22 engineers who have extensive experience in
the tape industry. Many of these engineers are former employees of tape drive
companies such as Cipher, Archive Corporation and Conner, and have developed
significant expertise in electrical, mechanical and firmware design. Martin
Gray, the Company's co-founder, formerly served as Manager of R&D at Cipher, has
25 years of experience in the tape industry, is the inventor of several tape
patents and leads the Company's R&D efforts to develop new technologies.
 
    The Company's R&D focus allows it to develop both tape drives and robotics.
Overland believes that this capability provides the following advantages: (i)
the Company is not dependent on purchasing tape drives manufactured by third
parties other than Quantum's DLT drive; (ii) it has a better understanding of
tape technologies; and (iii) it can provide higher value-added content by
designing reliable products that better utilize the advantages of a specific
technology. The Company estimates that approximately two-thirds of its R&D
efforts relate to various aspects of data channels, data compression,
intelligent interfaces and firmware (embedded systems software) for the
management of electronic hardware and mechanical systems. The remaining
one-third of its R&D efforts relate to the development of reliable mechanisms
for robotics. In addition, Overland's work on tape drive architecture and
implementation includes the ability to develop and test a tape path, which is
the core of any tape technology.
 
                                       33
<PAGE>
    The Company's current robotic R&D efforts are focused on the LXG and the
LXC, added modules for the LibraryXpress product line. The Company shipped
prototype units of the LXG in November 1996 and expects to commence commercial
shipment of the LXG and the LXC before the end of the first quarter of calendar
year 1997. In addition, the Company has developed a new tape coding technique
utilizing the concept of "partial response maximum likelihood," which has the
capability of significantly expanding the capacity and throughput of any linear
tape technology. The Company has filed for a series of patents related to this
technique and expects to commence shipment of products utilizing this technique
by the end of the fourth quarter of calendar year 1997. No prototypes currently
exist for these products and there can be no assurance that the Company will
succeed in its efforts to commence shipment of these products within its
expected time frame or at all. In addition, enhancements to certain of the
Company's 36-track products are being made to increase their speed and
performance. R&D expenditures amounted to $3.4 million, $3.1 million and $3.7
million in fiscal years 1994, 1995 and 1996, respectively, representing 10.0%,
8.1% and 7.8% of net sales, respectively. The Company intends to spend 7.0% to
8.0% of net sales on research and development in fiscal year 1997.
 
    In addition, Overland believes that it benefits from its close relationship
with the University of California at San Diego ("UCSD"). For example, as a
member of the UCSD Center for Magnetic Recording Research ("CMRR"), the Company
has access to all of the published research of CMRR and uses the CMRR staff in
an advisory capacity regarding Overland's new concepts and technologies.
 
    Despite its R&D focus, there can be no assurance that the Company will be
able to identify, develop, manufacture, market or support new or enhanced
products successfully or on a timely basis or that new products will gain market
acceptance. See "Risk Factors--Rapid Technological Change and Dependence on New
Product Development."
 
MANUFACTURING
 
    The Company has a fully integrated factory in San Diego, California with
three separate production lines. Its newest line, set up in January 1996, was
established for the production of the LibraryXpress products. A second line is
used for the production of both 18-track and 36-track products and a third line
is used for 9-track products. All of the Company's production lines and
manufacturing processes have been certified by major OEM customers.
 
    Overland's manufacturing strategy is to perform product assembly,
integration and testing, while leaving component and piece-part manufacturing to
its supplier partners. The Company works closely with a group of regional,
national and international suppliers, which are carefully selected based on
their ability to provide quality parts and components that consistently meet the
Company's specifications and present and future volume requirements. A number of
the Company's parts and components are not available off the shelf, and are
specifically designed by the Company for integration into its products. The
number of suppliers is kept to a minimum to utilize their specific capabilities
across several product lines. Management of this supply chain is critical,
because the average material content of the Company's products represents
approximately 80% of cost of goods sold.
 
    Another important element of the Company's manufacturing strategy is related
to product design. In general, products are built to an intermediate stage or
standard module and are customized at the end of the manufacturing process to
meet specific customer needs or variations in product profiles. The Company
believes that this capability represents an effective way for the Company to
minimize its inventory levels while maintaining the ability to fill specific
customer orders in short lead times. Inventory planning and management is
coordinated closely with suppliers and customers to match the Company's
production to market demand. Product orders are confirmed and, in most cases,
shipped to the customer within one week. The Company fills orders as they are
received and therefore believes that its backlog levels are not indicative of
future sales. The backlog of firm orders deliverable within three months,
amounted to $2.0 million and $3.3 million at September 30, 1995 and 1996,
respectively.
 
                                       34
<PAGE>
    In its current facility, the Company has the capacity to support unit output
several times greater than its current run rate. All of its manufacturing lines
are capable of producing on a single shift double the capacity of the current
fiscal year forecast. The Company carefully controls and adjusts the staffing of
this capacity to meet the requirements at any specific time. Further capacity
increases could be achieved by adding multiple shifts or moving to a full-time
factory.
 
    The Company's products have a large number of components and subassemblies
produced by outside suppliers and it is highly dependent on such suppliers for
components and sub-assemblies, including read/ write heads, printed circuit
boards and integrated circuits, which are essential to the manufacture of the
Company's products. In addition, for certain of these items, the Company
qualifies only a single source of supply, which can magnify the risk of
shortages and decrease the Company's ability to negotiate with its suppliers on
the basis of price. Specifically, the Company's new LibraryXpress automated tape
libraries incorporate tape drives manufactured by Quantum, which is also a
competitor of the Company in that Quantum markets its own tape drives and tape
loader products. Currently, there are no alternative sources for the DLT tape
drives supplied by Quantum. The Company does not have a long-term contract with
Quantum, which could cease supplying DLT tape drives directly to the Company, in
which case the Company would be forced to obtain these drives from distributors,
if available, and at prices that would probably be higher. From time to time in
the past, the Company (and its competitors) have not been able to obtain as many
drives as they needed from Quantum due to drive shortages or quality issues. Any
prolonged inability to obtain adequate deliveries of DLT drives or other
critical component parts or supplies could have a material adverse effect on the
Company's business, financial condition and results of operations. During the
last 12 months, the Company has experienced problems with the quality and
timeliness of the supply of DLT drives and read-write heads, each of which is a
sole source component. Such problems have adversely affected the Company's sales
during this period. While the Company believes that the problems relating to
these components have been resolved, no assurance can be given that such
problems will not re-occur or that the Company will not experience similar or
more serious disruptions in supply in the future. See "Risk Factors--Dependence
on Certain Suppliers."
 
PROPRIETARY RIGHTS
 
    The Company believes that, because of the rapid pace of technological change
in the tape storage industry, patent, copyright, trademark and trade secret
protection are less significant than factors such as the knowledge, ability and
experience of the Company's personnel, new product introductions and product
enhancements. Notwithstanding, the Company relies on a combination of patent,
copyright, trademark and trade secret protection, non-disclosure agreements and
licensing arrangements to establish and protect its proprietary rights. Such
rights, however, may not preclude competitors from developing substantially
equivalent or superior products to those of the Company. As of December 1996,
the Company owns one United States patent and has six patent applications
pending in the United States and one internationally under the provisions of the
Patent Cooperation Treaty. There can be no assurance that patents will issue
from any of these pending applications or, if patents do issue, that any claims
allowed will be sufficiently broad to protect the Company's technology. In
addition, there can be no assurance that any patents that may be issued to the
Company will not be challenged, invalidated or circumvented, or that any rights
granted thereunder would provide proprietary protection to the Company. Although
the Company continues to implement protective measures and intends to defend its
proprietary rights, policing unauthorized use of the Company's technology or
products is difficult and there can be no assurance that these measures will be
successful. In addition, the laws of certain foreign countries may not protect
the Company's proprietary rights to the same extent as do the laws of the United
States.
 
    The Company has entered into a five-year cross-license agreement with IBM,
effective January 1, 1996. Pursuant to the terms of the agreement, the Company
may use any of the patents owned by IBM within certain designated areas of
technology and IBM may use any of the patents of the Company that were in
existence at the effective date of the agreement or which are issued during the
term of the
 
                                       35
<PAGE>
agreement. In consideration for this agreement, the Company is required to pay
royalty fees to IBM in an amount equal to 2.7% of world-wide revenues generated
from the Company's 18 and 36-track product sales, exclusive of those sold to
IBM.
 
EMPLOYEES
 
    The Company had 192 employees (full-time equivalent) as of September 30,
1996, including 44 in sales and marketing, 36 in research and development, 87 in
manufacturing and operations and 25 in finance, information systems, human
resources and other management. There are no collective bargaining contracts
covering any of the Company's employees and management believes that its
relationship with its employees is good.
 
PROPERTIES
 
    The Company leases all facilities used in its business. The Company's
headquarters are located in San Diego, California in a 3-building light
industrial complex, of which it currently occupies two buildings comprising
approximately 93,500 square feet. The Company also has a right of first refusal
on the third building which comprises an additional 27,000 square feet. The San
Diego facility houses all of the Company's manufacturing, research and
development and administrative functions as well as a major portion of sales,
sales administration, marketing and customer support. The Company also leases a
7,000 square foot facility located in Wokingham, England which houses sales,
sales administration and customer support for the European marketplace. Two
other small facilities are leased in Longmont, Colorado and in Nashua, New
Hampshire for the development of R&D prototypes and an OEM sales office,
respectively. The Company believes that its facilities are suitable for their
uses and are, in general, adequate for the Company's current and identified
future needs.
 
LEGAL PROCEEDINGS
 
    There are no legal proceedings pending, or, to the knowledge of management,
threatened against the Company.

(3) In accordance with the rules of the Securities and Exchange Commission, the
    potential realizable values for the options are based on assumed rates of
    stock price appreciation of 5% and 10% compounded annually from the date the
    respective options were granted to their expiration dates. The gains shown
    are net of the option exercise price and do not include deductions for taxes
    or other expenses associated with their exercise. These assumed rates of
    appreciation do not represent the Company's estimate or projection of the
    appreciation of shares of the Common Stock and actual gains, if any, on
    stock option exercises will depend on the future performance of the Common
    Stock.

STOCK AND EMPLOYEE BENEFIT PLANS
 
    1995 STOCK OPTION PLAN.  The Company's 1995 Stock Option Plan (the "1995
Plan") was adopted by the Board of Directors in October 1995 to attract, retain
and provide additional incentive to directors, employees and consultants of the
Company. Options granted under the 1995 Plan may be either incentive stock
options as defined in Section 422A of the Internal Revenue Code of 1986, as
amended (the "IRC"), or non-statutory stock options. A total of 372,500 shares
of Common Stock have been reserved for issuance under the 1995 Plan.
 
    The 1995 Plan is administered by the Compensation Committee which has the
authority to determine the terms of the options granted. In the event of option
grants or stock purchase rights awarded to directors of the Company, the
administration of such grants or awards must comply with Rule 16 promulgated
under the Securities Exchange Act of 1934, as amended. Each option has a term
specified in its option agreement; provided, however, that no term can exceed
ten years from the date of grant and options must be exercisable at the rate of
at least 20% per year over five years from the date of grant. In the case of an
incentive stock option granted to an optionee who, at the time the option is
granted, owns stock representing more than 10% of the voting power of all
outstanding classes of stock of the Company or any of its subsidiaries (a "10%
Optionee"), the term of the option cannot exceed five years from the grant date.
No option granted under the 1995 Plan may be transferred by the optionee other
than by will or the laws of descent or distribution and each option may be
exercised, during the lifetime of the optionee, only by such optionee. In the
event an optionee's service terminates for any reason other than death or total
disability, any options held which have not yet vested will expire and become
unexercisable. All of the optionee's options which have vested shall expire and
become unexercisable on the earliest of the expiration date stated in the
agreement or the date 30 days (or six months after total disability) after the
termination of the optionee's service. The number of shares under each option
and the price of any shares under such option may be adjusted in a manner
consistent with any capital adjustment resulting from a stock dividend, stock
split, recapitalization, reorganization, merger, consolidation, liquidation, or
a combination or exchange of shares.
 
    The exercise price of all incentive stock options granted under the 1995
Plan must be no less than 100% of the fair market value per share on the date of
grant. In the case of non-statutory stock options, the per share exercise price
may be no less than 85% of the fair market value per share on the date of grant.
With respect to a 10% Optionee, the exercise price of any option granted must be
no less than 110% of the fair market value per share on the date of grant. Each
option is designated in the written option agreement as either an incentive
stock option or a non-statutory stock option. However, to the extent that the
aggregate fair market value of shares subject to an optionee's incentive stock
options, which become exercisable for the first time during any year exceeds
$100,000, such excess options shall be treated as non-statutory stock options.
 
    At September 30, 1996, there were outstanding options under the 1995 Plan to
purchase an aggregate of 14,000 shares of Common Stock at an exercise price of
$3.00. The 1995 Plan will expire in 2005 unless terminated at an earlier date by
action of the Board of Directors. At September 30, 1996, there were outstanding
options under other stock option plans, which were previously terminated by the
Company, to purchase an aggregate of 801,296 shares of Common Stock at a
weighted average exercise price of $1.11.
 
    1996 EMPLOYEE STOCK PURCHASE PLAN. In December 1996, the Board of Directors
adopted the 1996 Employee Stock Purchase Plan (the "Purchase Plan"), the purpose
of which is to provide an opportunity for the Company's employees to purchase
shares of the Company's Common Stock and thereby have an additional incentive to
contribute to the prosperity of the Company. After the completion of this
Offering, the Purchase Plan will allow employees to purchase shares of Common
Stock through payroll deductions. An administrative committee appointed by the
Board of Directors (the "Administrative Committee") will determine periods of up
to 27 months (each an "Option Period"), during which each participant in the
Purchase Plan will be granted an option to purchase that number of shares of
Common Stock which may
 
                                       41
<PAGE>
be purchased with the payroll deductions accumulated on behalf of such
participant during each six-month period within a particular Option Period, as
approved by the Board of Directors. The Purchase Plan provides that (i) no
employee shall be entitled to accrue rights to purchase shares under the
Purchase Plan at a rate which exceeds $25,000 of the fair market value of such
stock (determined at the time the option is granted) for any calendar year in
which such option is outstanding at any time, and (ii) the maximum number of
shares subject to any option shall not exceed 1,500. Employees participating in
the Purchase Plan may purchase shares of Common Stock under each option at a
price per share equal to the lower of (x) 85% of the fair market value of the
Common Stock on the date of commencement of participation in the Purchase Plan
offering period or (y) 85% of the fair market value of a share of Common Stock
on the date of purchase. Generally, any employee, including executive officers,
regularly employed on a full-time basis by the Company or by Overland Data
(Europe) Limited, a wholly owned subsidiary of the Company ("Overland Data
Europe"), on the first day of each Option Period is eligible to participate in
the Purchase Plan, subject to minimum eligibility periods, if any, as
established by the Administrative Committee. Participants may authorize payroll
deductions of up to 15% of their compensation, including base, overtime and
commissions, for the purchase of shares of Common Stock under the Purchase Plan.
The Purchase Plan authorizes the Company to issue up to 250,000 shares of Common
Stock pursuant to the Purchase Plan. As of the date hereof, no shares of Common
Stock have been purchased under the Purchase Plan. The Purchase Plan will
terminate in January 2007.
 
    401(K) PLAN.  In February 1994, the Company adopted the Overland Data, Inc.
On-Track 401(k) Savings Plan (the "401(k) Plan"), that covers all eligible
employees of the Company who complete six months of service and are at least 21
years old. Employees may elect to defer up to 15% of their eligible compensation
(not to exceed the statutorially prescribed annual limit) in the form of
elective deferral contributions to the 401(k) Plan. The elective deferral
contributions are fully vested and nonforfeitable at all times and are invested
in accordance with the directions of the participants. The 401(k) Plan is
intended to qualify under Section 401 of the IRC, so that employee contributions
and income earned on such contributions are not taxable to employees until
withdrawn. The Company currently does not make matching contributions under the
401(k) Plan.
 
LIMITATION OF LIABILITY AND INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
    The Company's Articles of Incorporation (the "Articles") include a provision
that eliminates the personal liability of its directors for monetary damages to
the fullest extent permissible under California law. This limitation has no
effect on a director's liability (i) for acts or omissions that involve
intentional misconduct or a knowing and culpable violation of law, (ii) for acts
or omissions that a director believes to be contrary to the best interests of
the Company or its shareholders or that involve the absence of good faith on the
part of the director, (iii) for any transaction from which a director derived an
improper personal benefit, (iv) for acts or omissions that show a reckless
disregard for the director's duty to the Company or its shareholders in
circumstances in which the director was aware, or should have been aware, in the
ordinary course of performing a director's duties, of a risk of a serious injury
to the Company or its shareholders, (v) for acts or omissions that constitute an
unexcused pattern of inattention that amounts to an abdication of the director's
duty to the Company or its shareholders, (vi) under Section 310 of the
California Corporations Code (the "California Code"), concerning contracts or
transactions in which the director has material financial interest or (vii)
under Section 316 of the California Code concerning directors' liability for
approval of certain corporate actions. The provision does not extend to acts or
omissions of a director in his capacity as an officer.
 
    The Articles also include an authorization for the Company to indemnify its
agents (as defined in Section 317 of the California Code), through bylaw
provisions, by agreement or otherwise, to the fullest extent permitted by law.
Pursuant to this provision, the Company's Bylaws (the "Bylaws") provide for
indemnification of the Company's directors, officers and agents. In addition,
the Company, has entered into indemnification agreements with all directors and
executive officers and provide the maximum
 
                                       42
<PAGE>
indemnification permitted by law. These agreements, together with the Articles
and the Bylaws, may require the Company, among other things, to indemnify these
directors or executive officers (other than liability resulting from willful
misconduct of a culpable nature), to advance expenses to them as they are
incurred, provided that they undertake to repay the amount advanced if it is
ultimately determined by a court that they are not entitled to indemnification,
and to obtain directors' and officers' insurance if available on reasonable
terms. Section 317 of the California Code and the Bylaws make provision for the
indemnification of officers, directors and other corporate agents in terms
sufficiently broad to indemnify such persons under certain circumstances, for
liabilities (including reimbursement of expense incurred) arising under the
Securities Act.
 
    The Company, with the approval of the Board of Directors, intends to obtain
directors' and officers' liability insurance prior to the effectiveness of this
Offering.
 
                              CERTAIN TRANSACTIONS
 
    Seagate is the owner of 17.1% of the outstanding shares of Common Stock
immediately prior to this Offering and is a Selling Shareholder in the Offering.
Seagate has been a supplier to the Company of certain components used in the
production of its 18-track products. In addition, Michael L. Huntley, Senior
Vice President and General Manager, Tape Operations of Seagate Storage Products,
has served on the Company's Board of Directors since December 1996 and is
expected to continue to serve on the Board of Directors after the closing of
this Offering. During the fiscal year ended June 30, 1996, the Company purchased
approximately $1.3 million of products from Seagate under standard purchase
orders at prices and terms which the Company believes are no less favorable than
could be obtained from an independent third party.
 
    In addition, Overland Data Europe entered into a lease agreement in June
1996 with Seagate Distribution (UK) Limited, a subsidiary of Seagate. The lease
is for a 7,000 square foot facility located in Wokingham, England, which houses
sales, sales administration and customer support for the Company's European
operations. The lease has a three-year term and a monthly rent of approximately
$5,100. The Company believes that the lease was obtained at rental rates and
terms which are no less favorable than could be obtained from an independent
third party.
 
    During the three months ended September 30, 1996, the Company sold shares of
Common Stock to three of its executive officers at the then fair market value as
set by the Board of Directors of $3.00 per share. Scott McClendon, the Company's
President and Chief Executive Officer, purchased 21,000 shares for total
consideration of $63,000; Martin D. Gray, the Company's Vice President and
Secretary, purchased 6,250 shares for total consideration of $18,750; and
Charles R. Earnhart, the Company's Vice President of Operations, purchased 1,500
shares for total consideration of $4,500.
 
    During fiscal year 1996, the Company sold shares of Common Stock to three of
its executive officers pursuant to purchase transactions or the exercise of
stock options. Scott McClendon purchased a total of 271,011 shares at an average
price of $1.13 per share for total consideration of $306,809. Frank R.
Kirchhoff, the Company's Vice President of Sales, purchased 79,222 shares at an
average price of $1.10 per share for total consideration of $87,378. Charles
Earnhart, the Company's Vice President of Operations, purchased 22,350 shares at
$2.00 per share for total consideration of $44,700.
 
    During fiscal year 1994, the Company sold shares of Common Stock to three of
its executive officers at the then fair market value as set by the Board of
Directors of $0.80 per share. Scott McClendon purchased 56,250 shares for total
consideration of $45,000; Martin D. Gray purchased 12,700 shares for total
consideration of $10,160; and Robert J. Scroop, the Company's Vice President of
Engineering, purchased 6,600 shares for total consideration of $5,280.

                          DESCRIPTION OF CAPITAL STOCK
 
COMMON STOCK
 
    The authorized capital stock of the Company consists of 25,000,000 shares of
Common Stock, no par value ("Common Stock"). As of September 30, 1996, 5,206,325
shares of Common Stock were issued and outstanding and were held of record by 83
shareholders. Each holder of Common Stock is entitled to one vote for each share
held of record on each matter submitted to a vote of shareholders. Subject to
preferences that may be granted to the holders of Preferred Stock, each holder
of Common Stock is entitled to share ratably in distributions to shareholders
and to receive ratably such dividends as may be declared by the Board of
Directors out of funds legally available therefor and, in the event of the
liquidation or dissolution of the Company, is entitled to share ratably in all
assets of the Company remaining after payment of liabilities. Holders of Common
Stock have no conversion, preemptive or other subscription rights, and there are
no redemption rights or sinking fund provisions with respect to the Common
Stock. The outstanding Common Stock is, validly issued, fully paid and
non-assessable.
 
    Additional shares of Common Stock may be issued from time to time by the
Company. The Articles provide that the Board of Directors has no power to alter
the rights of any outstanding shares of Common Stock. Certain other provisions
of the Articles affect the rights of holders of Common Stock and may have the
effect of delaying, deferring or preventing a change in control of the Company.
 
PREFERRED STOCK
 
    As of September 30, 1996, 318,397 shares of Series A Preferred Stock,
731,429 shares of Series B Preferred Stock and 1,286,747 shares of Series C
Preferred Stock were issued and outstanding and held of record by 12, six and
one shareholders, respectively. All outstanding shares of Series A, B and C
Preferred Stock will be converted into an aggregate of 2,336,573 shares of
Common Stock upon the closing of this Offering and such shares of Preferred
Stock will no longer be authorized, issued or outstanding.
 
WARRANT
 
    In connection with the establishment of its bank line of credit in May 1995,
the Company issued to Imperial Bank (the "Bank") a warrant (the "Warrant")
exercisable to purchase 17,046 shares of Common Stock at $4.40 per share.
Pursuant to its terms, the Warrant is exercisable at any time on or after May
15, 1995 and unless exercised, the Warrant will automatically expire on May 15,
2000.
 
CALIFORNIA LAW AND CERTAIN PROVISIONS OF THE COMPANY'S ARTICLES OF INCORPORATION
 
    The Board of Directors has authorized, subject to shareholder approval, an
amendment to the Articles which provides for fair price provisions (the "Fair
Price Provisions"), that require the approval of the holders of two-thirds of
the Voting Stock (as defined therein) and satisfaction of certain minimum price
criteria and procedural conditions as a condition to specified business
combinations (each a "Business Combination") with any beneficial owner of shares
possessing 10% or more of the Voting Stock (a "Major Shareholder").
 
    A Business Combination includes, among other transactions, the following:
(i) any merger or consolidation of the Company with or into a Major Shareholder;
(ii) any sale, lease, exchange, transfer or distribution to Shareholders or
other disposition of a substantial part of the assets of the Company; (iii) the
purchase, exchange, lease or other acquisition by the Company of substantially
all of the assets of a Major Shareholder; (iv) the issuance of any securities of
the Company, 80% or more of which are issued to a Major Shareholder, and (v) any
reclassification of the Voting Stock which has the effect of increasing the
proportionate amount of Voting Stock which is owned by a Major Shareholder.
 
                                       46
<PAGE>
    The Fair Price Provisions require, among other things, that the
consideration to be paid to the Company's Shareholders in a Business Combination
be not less than the higher of (i) the highest price per share paid by the Major
Shareholder in acquiring any of the Voting Stock or (ii) an amount which bears
the same or greater percentage relationship to the market price of the Voting
Stock as the highest price per share determined in item (i) bears to the market
price of the Voting Stock prior to the acquisition of the Voting Stock by such
Major Shareholder.
 
    Under Section 710 of the General Corporation Law, the Fair Price Provisions
constitute a supermajority vote requirement. Section 710 provides that
amendments to the articles of incorporation of a California corporation that
include a supermajority vote requirement cease to be effective two years after
the filing of the most recent filing of the amendment to adopt or readopt the
supermajority vote requirement. However, at any time within one year before the
expiration date, a supermajority vote requirement may be renewed unless: (i) the
Business Combination was approved by the Board of Directors of the corporation
prior to the Major Shareholder involved in the Business Combination becoming
such; (ii) the Major Shareholder involved in the Business Combination sought and
obtained the unanimous prior approval of the Board of Directors to become a
Major Shareholder and the Business Combination was approved by not less than
eighty percent (80%) of the directors of the corporation; or (iii) the Business
Combination was approved by not less than ninety percent (90%) of the directors
of the corporation.

                        SHARES ELIGIBLE FOR FUTURE SALE
 
    Prior to this Offering, there has been no public market for the Common Stock
of the Company, and no prediction can be made as to the effect, if any, that
market sales of shares or the availability of such shares for sales will have on
the market price of the Common Stock prevailing from time to time. Sales of
substantial amounts of Common Stock, or the perception that such sales could
occur, could adversely affect the prevailing market price of the common Stock
and the ability of the Company to raise capital through a sale of its
securities.
 
    Upon completion of this Offering, the Company will have 9,742,898 shares of
Common Stock outstanding (assuming no exercise of the Underwriters'
over-allotment option to purchase up to an additional 405,000 shares). The
2,700,000 shares sold in this Offering (3,105,000 shares if the Underwriters'
over-allotment option is exercised in full) will be freely tradable without
restriction under the Securities Act, except for any such shares held at any
time by an "affiliate" of the Company, as such term is defined under Rule 144
promulgated under the Securities Act.
 
    The remaining 7,042,898 shares were issued and sold by the Company in
private transactions and may be publicly sold only if registered under the
Securities Act or sold in accordance with an applicable exemption from
registration, such as Rule 144. In general, under Rule 144, as currently in
effect, a person who has beneficially owned shares for at least two years,
including an "affiliate," as that term is defined in Rule 144, is entitled to
sell, within any three-month period, a number of "restricted" shares that does
not exceed the greater of one percent (1%) of the then outstanding shares of
Common Stock (97,429 shares immediately after this Offering) or the average
weekly trading volume during the four calendar weeks preceding such sale. Sales
under Rule 144 are subject to certain manner of sale limitations, notice
requirements and the availability of current public information about the
Company. Rule 144(k) provides that a person who is not deemed an "affiliate" and
who has beneficially owned shares for at least three years is entitled to sell
such shares at any time under Rule 144 without regard to the limitations
described above.
 
    The parties to the Investor's Rights Agreement, who in the aggregate will
hold 2,605,726 shares of Common Stock after the completion of this Offering,
have been granted certain demand and "piggy-back" registration rights if the
Company proposes to register any of its equity securities under the Securities
Act (other than registration of employee benefit plans or in connection with an
acquisition), subject to customary underwriting cut-back and hold-back
provisions. The registration rights granted under the Investor's Rights
Agreement will terminate upon the closing of this Offering; provided, however,
that the parties to the Investor's Rights Agreement which continue to own more
than two percent (2%) of the outstanding shares of Common Stock will have such
registration rights until the fifth anniversary of the closing of this Offering.
The Company will pay all expenses relating to any such registration other than
underwriting discounts and commissions.
 
    The holder of the Warrant will be entitled to publicly resell the 17,046
shares of Common Stock issuable upon exercise thereof, subject to the provisions
of Rule 144, beginning 180 days after the date of the Underwriting Agreement
relating to this Offering (or sooner with the consent of Jefferies & Company,
Inc.). Pursuant to the terms of the Warrant, the holder of the Warrant has been
granted the same registration rights as those granted to the parties to the
Investors' Rights Agreement. Upon the closing of this Offering, the holder will
enter into a new registration rights agreement with the Company, which will, at
a minimum, grant to the holder certain "piggyback" registration rights.
 
    The Company has agreed with the Underwriters not to sell or otherwise
dispose of any shares of Common Stock for a period of 180 days from the date of
this Prospectus without the prior written consent of Jefferies & Company, Inc.
In addition, the directors, officers and current shareholders of the Company,
beneficially holding (upon completion of this Offering) an aggregate of
6,306,985 shares, have agreed not to sell or otherwise dispose of any such
shares for a period of 180 days from the date of this Prospectus without the
prior written consent of Jefferies & Company, Inc.

    The Company is unable to estimate the number of shares that may be sold in
the future by its existing shareholders or the effect, if any, that sales of
shares by such shareholders will have on the market price of the Common Stock
prevailing from time to time. Sales of substantial amounts of Common Stock by
existing shareholders could adversely affect prevailing market prices.

    The Underwriting Agreement provides that the obligation of the Underwriters
is subject to certain conditions precedent, including the absence of any
material adverse change in the Company's business and the receipt of certain
certificates, opinion and letters from the Company and its counsel. The nature
of the Underwriters' obligation is such that they are committed to purchase all
shares of the Common Stock offered hereby (other than those covered by the
over-allotment option described below), if any such shares are purchased.
 
    The Underwriters propose to offer the shares of Common Stock directly to the
public initially at the public offering price set forth on the cover page of
this Prospectus, and to certain dealers at such price less a discount not in
excess of $    per share. The Underwriters may allow, and such dealers may
reallow, a concession not in excess of $    per share to certain other dealers.
After the initial public offering of the Common Stock, the public offering price
and other selling terms may be changed by the Representatives.
 
    The Company has granted to the Underwriters an option, exercisable at any
time during the 30-day period from the date of the Prospectus, to purchase up to
405,000 additional shares of the Common Stock at the public offering price set
forth on the cover page of this Prospectus, less the underwriting discount. Such
shares will be sold, in whole or in part, either by the Company or the Selling
Shareholders, at the option of the Company. To the extent such option is
exercised, each Underwriter will become obligated, subject to certain
conditions, to purchase additional shares of Common Stock proportionate to such
Underwriter's initial commitment as indicated in the preceding table. The
Underwriters may exercise such right of purchase only for the purpose of
covering over-allotments, if any, made in connection with the sale of the shares
of Common Stock. If purchased, the Underwriters will offer such additional
shares on the same terms as those on which the 2,700,000 shares are being
offered hereby.
 
    The Company, executive officers, directors and certain other shareholders
have agreed that they will not, without the prior written consent of Jefferies &
Company, Inc., offer, sell or otherwise dispose of any
 
                                       50
<PAGE>
shares of Common Stock, options or warrants to acquire shares of Common Stock or
securities exchangeable for or convertible into shares of Common Stock owned by
them for a period of 180 days after the date of this Prospectus.
 
    Prior to this Offering, there has been no public market for the Common
Stock. The initial public offering price has been determined by negotiations
among the Company, the Selling Shareholders and the Representatives. Among the
factors considered in such negotiations were the history of, and the prospects
for, the Company and the industries in which it competes, an assessment of the
Company's management, the Company's past and present operations, its past and
present earnings and the trend of such earnings, the general condition of the
securities market at the time of its offering and the market prices of publicly
traded common stock of comparable companies in recent periods.
 
    The Company and the Selling Shareholders have agreed to indemnify the
Underwriters against certain liabilities that may be incurred in connection with
this Offering, including liabilities under the Securities Act, or to contribute
to payments that the Underwriters may be required to make in respect thereof.
 
    The Underwriters do not intend to confirm sales to accounts over which they
exercise discretionary authority.
 
    The Company has been advised by the Representatives that the Representatives
presently intend to make a market in the Common Stock offered hereby; however,
the Representatives are not obligated to do so, and any market making activity
may be discontinued at any time without notice. There can be no assurance that
an active public market for the Common Stock will develop and continue after
this Offering.
 
                                 LEGAL MATTERS
 
    The validity of the issuance of the shares of Common Stock offered hereby
will be passed upon for the Company by Baker & McKenzie, San Diego, California.
Brobeck, Phleger & Harrison LLP, San Francisco, California, will pass upon
certain legal matters for the Underwriters. Two partners of Baker & McKenzie own
an aggregate of 10,715 shares of the Company's Common Stock.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and
  Shareholders of Overland Data, Inc.
 
In our opinion, the accompanying consolidated balance sheet and the related
consolidated statements of operations, of shareholders' equity and of cash flows
present fairly, in all material respects, the financial position of Overland
Data, Inc. and its subsidiaries at June 30, 1996 and 1995, and the results of
their operations and their cash flows for each of the three years in the period
ended June 30, 1996, in conformity with generally accepted accounting
principles. 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 of these statements in
accordance with generally accepted auditing standards which 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, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for the opinion expressed
above.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
NOTE 1--OPERATIONS AND SUMMARY OF ITS SIGNIFICANT ACCOUNTING POLICIES
 
GENERAL
 
Overland Data, Inc. (the "Company") was incorporated on September 8, 1980 under
the laws of the state of California. The Company designs, develops,
manufactures, markets and supports magnetic tape data storage systems used by
businesses for backup, archival and data interchange functions. The Company's
fiscal year ends on the Sunday closest to June 30. For ease of presentation the
Company's year end is deemed to be June 30. Each of fiscal years 1994, 1995 and
1996 included 52 weeks.
 
PRINCIPLES OF CONSOLIDATION
 
The consolidated financial statements include the accounts of the Company and
its wholly-owned subsidiaries, Overland Data (Europe) Limited and Overland Data
Export Limited, a foreign sales corporation. All significant intercompany
accounts and transactions have been eliminated.
 
MANAGEMENT ESTIMATES AND ASSUMPTIONS
 
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 disclosures of
contingent assets and liabilities at the date of the financial statements and
reported amounts of revenues and expenses during the reporting period. Actual
results could differ from those estimates.
 
REVENUE RECOGNITION
 
Sales are recognized upon shipment of products to customers and are not subject
to any specific right of return or price protection, except for any defective
product which may be returned under the Company's warranty policy.
 
WARRANTY COSTS
 
The Company generally offers a two-year return-to-factory warranty on its
products and records a provision for estimated future warranty costs at the time
of shipment. It also contracts with outside vendors to provide service relating
to various on-site and extended warranties which are offered for sale to
customers. Warranty revenues and amounts paid in advance to outside service
organizations for the entire warranty period are included in the financial
statements in sales and cost of goods sold, respectively.
 
RESEARCH AND DEVELOPMENT COSTS
 
Research and development costs are expensed as incurred.
 
FAIR VALUE OF FINANCIAL INSTRUMENTS
 
It is management's belief that the carrying amounts shown for the Company's
financial instruments are reasonable estimates of their related fair value based
on their terms or short-term nature.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
NOTE 1--OPERATIONS AND SUMMARY OF ITS SIGNIFICANT ACCOUNTING POLICIES
(CONTINUED)
EXPORT SALES
 
Export sales by the Company, principally in Europe, for the fiscal years ended
June 30, 1994, 1995 and 1996 were approximately $5,753,000, $7,737,000 and
$12,775,000, respectively. Substantially all export sales are denominated in
U.S. dollars.
 
CONCENTRATION OF CREDIT RISK
 
The Company's customers include original equipment manufacturers, integrators,
distributors, value added resellers and end users. Financial instruments which
potentially subject the Company to concentrations of credit risk are primarily
accounts receivable. The Company performs ongoing credit evaluations of its
customers, generally requires no collateral and maintains allowances for
potential credit losses and sales returns. The Company's largest single customer
accounted for approximately 36%, 21% and 23% of sales in fiscal years 1994, 1995
and 1996, respectively, and approximately 18% and 33% of accounts receivable at
June 30, 1995 and 1996, respectively. No other customer accounted for 10% or
more of sales in any of the three years presented.
 
CASH EQUIVALENTS
 
Highly liquid investments with original maturities of three months or less are
classified as cash equivalents.
 
INVENTORIES
 
Inventories are stated at the lower of cost (first-in-first-out method) or
market.
 
PROPERTY AND EQUIPMENT
 
Property and equipment are recorded at cost. Depreciation is computed using the
straight-line method over the estimated useful lives of the depreciable assets
(generally two to five years). Leasehold improvements are amortized on a
straight-line basis over the shorter of the useful life of the asset or the
lease term. Expenditures for normal maintenance and repair are charged to
expense as incurred and improvements are capitalized. Upon the sale or
retirement of property or equipment, the asset cost and related accumulated
depreciation are removed from the respective accounts and any gain or loss is
included in the results of operations.
 
INTANGIBLE ASSETS
 
Intangible assets, resulting from the acquisition of assets relating to certain
product lines (Note 2), are amortized using the straight-line method over five
years (the estimated life of the products). Accumulated amortization was
$432,000 in 1995 and $570,000 in 1996. The Company periodically considers
whether the sum of the estimated future net cash flows generated from the sale
of related products is in excess of the carrying amount of the intangible asset
(net realizable value). The carrying amount would be reported as the lower of
cost (net of amortization) or net realizable value. No such impairment losses
have been recorded by the Company.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
NOTE 1--OPERATIONS AND SUMMARY OF ITS SIGNIFICANT ACCOUNTING POLICIES
(CONTINUED)
LONG-LIVED ASSETS
 
The Company assesses potential impairments to its long-lived assets when there
is evidence that events or changes in circumstances have made recovery of the
asset's carrying value unlikely. An impairment loss would be recognized when the
sum of the expected future net cash flows is less than the carrying amount of
the asset. No such impairment losses have been identified by the Company.
 
FOREIGN CURRENCY REMEASUREMENT
 
The assets and liabilities of the foreign subsidiaries have been remeasured into
U.S. dollars at year-end exchange rates. Revenues and expenses have been
remeasured at average exchange rates during the year. Gains or losses resulting
from remeasurement and from foreign currency transactions are recognized
currently in operating results and were not significant in any year presented.
 
INCOME TAXES
 
The Company provides for income taxes utilizing the provisions of Statement of
Financial Accounting Standards No. 109 (SFAS 109). Under the asset and liability
method of SFAS 109, a deferred tax asset and/ or liability is computed for both
the expected future impact of differences between the financial statement and
tax bases of assets and liabilities, and for the expected future tax benefit to
be derived from tax credits and loss carryforwards. SFAS 109 also requires the
establishment of a valuation allowance to reflect the likelihood of realization
of deferred tax assets.
 
NEW ACCOUNTING PRONOUNCEMENT
 
In October 1995, the FASB issued Statement of Financial Accounting Standards No.
123, "Accounting for Stock-Based Compensation" (SFAS 123). The Company does not
intend to adopt the measurement provisions of SFAS 123 with regard to
employee-based stock compensation, but will adopt the required disclosure
provisions during the year ending June 30, 1997.
 
NET INCOME PER SHARE
 
Net income per share is computed based on the weighted average number of shares
of Common Stock and common stock equivalents, using the treasury stock method,
outstanding during the respective periods. Pursuant to Securities and Exchange
Commission Staff Accounting Bulletin No. 83, all issuances of Common Stock and
all stock options granted within one year prior to the filing of the Company's
registration statement for its planned initial public offering and through the
effective date thereof have been included as outstanding for all periods
presented using the treasury stock method.
 
INTERIM RESULTS (UNAUDITED)
 
The accompanying balance sheet at September 30, 1996 and the related statements
of operations and of cash flows for the three months ended September 30, 1995
and 1996, and the statement of shareholders' equity for the three months ended
September 30, 1996 are unaudited. In the opinion of management, these statements
have been prepared on the same basis as the audited financial statements and
include all adjustments, consisting only of normal recurring adjustments,
necessary for the fair statement of results of the interim periods. The data
disclosed in these notes to the financial statements at such date and for such
periods are also unaudited.

The unaudited pro forma information presented in the accompanying balance sheet
as of September 30, 1996 reflects the conversion of all outstanding shares of
Preferred Stock into 2,336,573 shares of Common Stock, which will occur upon
completion of the Company's planned initial public offering.
 
NOTE 2--ACQUISITIONS
 
CIPHER ACQUISITION
 
In May 1993 and October 1993, the Company acquired certain assets from Archive

The Company has a $5,000,000 revolving credit facility which is collateralized
by substantially all of the Company's assets and expires on November 5, 1998.
Under terms of the agreement, the Company may borrow the lesser of (1)
$5,000,000 or (2) 80% of eligible accounts receivable plus an overadvance at
June 30, 1996 of $1,200,000. The overadvance amount is reduced semi-annually by
$150,000 on November 1 and May 1. Borrowings under the line may be in the form
of working capital loans, which bear interest at the bank's prime rate plus 0.5%
(8.75% at June 30, 1996), or banker's acceptances priced at the banker's
acceptance rate plus 2.5%. The Company is required to maintain certain covenants
and financial ratios including working capital and net worth ratios, and pays a
0.5% annual commitment fee on the unused credit if the average amount borrowed
for any quarter is less than $2,500,000. The agreement also prohibits the
payment of dividends without prior bank approval. The Company is in compliance
with the terms of the agreement. As of June 30, 1996, $3,200,000 was available
for borrowing under this credit facility.

During the fiscal year ended June 30, 1996, the Company reduced the deferred tax
valuation allowance by $997,000 to recognize deferred tax assets. Based on
management's assessment and the Company's current profitability, management
believes it is more likely than not that the deferred tax asset will be realized
through future taxable earnings or alternative tax strategies. The 1996
provision does not reflect a research and development credit due to a federally
imposed one year suspension.
 
Deferred income taxes at June 30, 1995 and 1996 comprised:

NOTE 6--CONVERTIBLE REDEEMABLE PREFERRED STOCK
 
The Company has outstanding three series of Preferred Stock which have no par
value and are stated in the balance sheet at their original issue price, which
is equivalent to their redemption value. Each share of Series A, B and C
Preferred Stock (i) is voting, (ii) is convertible at any time at the option of
the holder into one share of Common Stock subject to certain anti-dilution and
automatic conversion provisions, (iii) participates equally with Common Stock
with respect to dividends, (iv) is redeemable at the option of the holder at a
price of $1.15, $1.75 and $2.76 per share, respectively, (v) upon liquidation of
the Company is entitled to receive $1.15, $1.75 and $2.76, per share,
respectively, in preference to any distributions to common shareholders, and
(vi) in the event of a sale of the Company's Common Stock in an initial public
offering, each unredeemed share will be automatically converted to one share of
Common Stock.
 
The Preferred Stock is redeemable in three equal annual installments and any
unredeemed shares automatically convert to Common Stock. Scheduled redemption
dates are as follows: Series A--May 1995, 1996 and 1997; Series B--December
1996, 1997 and 1998 and Series C--May 1997, 1998 and 1999. None of the holders
of Series A Preferred Stock elected to redeem their shares at the first two
installment dates and, therefore, the shares were converted into Common Stock. A
total of 318,396 and 318,397 shares with a value of $367,000 and $367,000 were
converted at each installment date in 1995 and 1996, respectively. The combined
aggregate amount of future redemption requirements for the Preferred Stock is
$1,978,000 (991,123 shares) in 1997, $1,611,000 (672,726 shares) in 1998 and
$1,611,000 (672,724 shares) in 1999.
 
NOTE 7--STOCK OPTIONS AND WARRANT
 
The Company has a number of stock option plans which provide for the issuance of
options to employees, officers and directors. The exercise price of a stock
option is generally equal to the fair market value of the Company's Common Stock
as determined by its Board of Directors on the date the option is granted.
Certain of the plans permit options granted to qualify as "Incentive Stock
Options" under the Internal Revenue Code while other plans are specified as
non-qualified. In addition, certain of the non-qualified plans call for 100%
vesting of outstanding options upon a change of control of the Company. Options
generally vest at a rate of 25 percent per year over a period of four years from
the date of grant and expire after a period not to exceed ten years, except in
the event of termination, whereupon vested shares must be exercised within 30
days, or upon death or disability, where a six month exercise period is
specified.

ITEM 14. INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
    Section 317 of the California Corporations Code permits a corporation to
indemnify its directors, officers, employees and other agents in terms
sufficiently broad to permit indemnification (including reimbursement for
expenses) under certain circumstances for liabilities arising under the
Securities Act of 1933, as amended (the "Securities Act").
 
    The Registrant's Articles of Incorporation (the "Articles") and Bylaws (the
"Bylaws") provide for the indemnification of directors and officers to the
maximum permitted by the California Corporations Code and authorize the
indemnification by the Registrant of other officers, employees and other agents
as set forth in the California Corporations Code. The Registrant has entered
into indemnification agreements with its directors and executive officers, in
addition to the indemnification provided for in the Articles and Bylaws.
 
    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 December 1993, the Registrant has sold and issued the following
securities without registration under the Securities Act:
 
    During the period from December 1993 to December 1996, the Company granted
to its employees, officers, directors and consultants under its various stock
option plans incentive and non-statutory stock options which were exercisable
into an aggregate of 854,193 shares of Common Stock. During the same period, the
Company also sold 690,622 shares of Common Stock to its employees, former
employees, officers and directors for total cash consideration of $751,177.
 
    The sales and issuances of the securities in the transactions described in
the above paragraph were deemed to be exempt from registration under the
Securities Act in reliance upon (i) Rule 701 promulgated
 
                                      II-1
<PAGE>
thereunder as transactions pursuant to a compensatory benefit plan or a written
contract relating to compensation, or (ii) Section 4(2) thereof and Regulation D
promulgated thereunder as transactions by an issuer not involving a public
offering.
 
    The recipients represented their intention to acquire the securities for
investment only and not with a view to the distribution thereof. Appropriate
legends are affixed to the stock certificates issued in such transactions.
Similar legends were imposed in connection with any subsequent sales of 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
may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the foregoing provisions, 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 Securities Act
and is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer or controlling person of the Registrant
in the successful defense of any action, suit, or proceeding) is asserted by
such director, officer or controlling person in connection with the securities
being registered, the Registrant will, unless in the opinion of its counsel the
matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Securities Act and will be governed by
the final adjudication of such issue.
 
    The undersigned Registrant undertakes that: (1) for purposes of determining
any liability under the Securities Act, the information omitted from the form of
prospectus filed as part of this 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 Securities Act shall be deemed to be
part of this Registration Statement as of the time it was declared effective,
and (2) for the purpose of determining any liability under the Securities 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 offering of such securities at that time shall be deemed to be the
initial bona fide offering thereof.
 
    The undersigned Registrant hereby undertakes to provide to the Underwriter
at the Closing, as specified in the Underwriting Agreement, certificates in such
denominations and registered in such names as required by the Underwriters to
permit prompt delivery to each purchaser.

                          CERTIFICATE OF AMENDMENT OF
                           ARTICLES OF INCORPORATION
                                      OF 
                              OVERLAND DATA INC.

Robert M. Long and Martin D. Gray certify the:

           1. They are the President and Secretary, respectively, of Overland
Data Inc. (the "Corporation").

           2. Article FOUR of the articles of incorporation of the Corporation
is amended to read as follows:

          "FOUR:

           A. This Corporation is authorized to issue two classes of shares to
be designated respectively Series A Preferred Stock ("Series A Preferred Stock")
and Common Stock ("Common Stock"). The total number of shares of capital stock
that the Corporation is authorized to issue is one million, ninety five
thousand, five hundred nineteen (1,095,519). The total number of shares of
Series A Preferred Stock this Corporation shall have authority to issue is
ninety five thousand, five hundred nineteen (95,519). The total number of shares
of Common Stock this Corporation shall have the authority to issue is one
million (1,000,000).

           B. The powers, preference, rights, restrictions and other matters
relating to the Series A Preferred Stock are as follows:

           1. DIVIDENDS. No dividend shall be paid on or declared and set apart
for the shares of Common Stock for any dividend period unless at the same time a
like dividend for the same dividend period, shall be paid on or declared and set
apart for the shares of Series A Preferred Stock, on an as converted basis.

           2. LIQUIDATION RIGHTS.

           (a) In the event of any liquidation, dissolution, or winding up of 
the Corporation, whether voluntary or involuntary, the holders of each share 
of Series A Preferred Stock then outstanding shall be entitled to be paid Out 
of the assets of the Corporation available for distribution to its 
shareholders, before any payment or declaration and setting 

<PAGE>

apart for payment of any amount shall be made in respect of the Common Stock, 
an amount equal to $11.516 per share plus all declared but unpaid dividends 
on each share, of Series A Preferred Stock, and no more. If upon liquidation 
dissolution, or winding up of the Corporation, whether voluntary or 
involuntary, the assets to be distributed to the holders of the Series A 
Preferred Stock shall be insufficient to permit the payment to such 
shareholders of the full preferential amount aforesaid, then all of the 
assets of the corporation to be distributed shall be distributed ratably to 
the holders of the Series A Preferred Stock. For the purposes of this Section 
B.2(a), any acquisition of the Corporation by means of merger or other form 
of corporate reorganization in which outstanding shares of the Corpora-.on 
are exchanged for securities or other consideration issued, or caused to be 
issued, by the acquiring corporation or its subsidiary (a "Corporate 
Reorganization") other than a transaction with a subsidiary of the 
Corporation or an entity under common control with the Corporation (and other 
than a transaction set forth in Section B.5(b)(ii)) shall be deemed to be a 
liquidation, dissolution or winding up of the Corporation.

           (b) After the payment or distribution to the holders of the Series 
A Preferred Stock of the full preferential amounts aforesaid, the holders of 
the Common Stock then outstanding shall be entitled to receive ratably all 
the remaining assets of the Corporation.

3. REDEMPTION.

           (a) At the individual option of each holder of shares of Series A
Preferred Stock, the Corporation shall redeem on the sixth, seventh and eighth
anniversary dates from the date of the first issuance of Series A Preferred
Stock (each a "Redemption Date"), at a price per shares equal to $11.516 (as
adjusted for any stock dividends, combinations or splits with respect to such
shares) plus declared but unpaid dividends on such shares (the "Redemption
Price"), at the rate of 33 1/3% of such holders, outstanding shares of Series A
Preferred Stock per year for each of the three Redemption Dates. The holders of
the Series A Preferred Stock will give written notice to the Corporation of
their election to be redeemed not less than ninety (90) days prior to each
anniversary date (the "Redemption Notice"). If any holders of Series A Preferred
Stock do not timely elect to be redeemed on any of the three Redemption Dates,
one-third of such holder's shares of series A Preferred Stock will automatically
be converted into Common Stock in accordance with the provisions set forth in
Section 

<PAGE>

B.5 below to effect the result that following the last Redemption Date all 
outstanding shares of Series A Preferred Stock shall either be redeemed or 
converted into Common Stock.
           
           (b) Except as provided in Section B.3(c), on or after the 
Redemption Date, each holder of Series A Preferred Stock shall surrender to 
this Corporation the certificate or certificates representing such shares, 
and thereupon each surrendered certificate will be cancelled and either (i) 
the appropriate Redemption Price of such shares shall be payable to the order 
of the person whose name appears on such certificate or certificates as the 
owner thereof, or (ii) the appropriate number of shares of Common Stock shall 
be issued for such shares to the owner thereof. In the event less than all 
the shares represented by any such certificate are redeemed or converted into 
Common Stock, a new certificate shall be issued representing the unredeemed 
or unconverted shares.

           (c) From and after the Redemption Date, unless there shall have been
a default in payment of the requested Redemption Price, all rights of the
holders of Series A Preferred Stock (except the right to receive the Redemption
Price without interest or shares of Common Stock upon surrender of their
certificate or certificates) shall cease with respect to such shares, and such
shares shall not thereafter be transferred on the books of the Corporation or be
deemed to be outstanding for any purpose whatsoever. If the funds of the
Corporation legally available for redemption of shares of Series A Preferred
Stock on any Redemption Date are insufficient to redeem the total number of
shares of Series A Preferred Stock to be redeemed on such date, those funds
which are legally available will be used to redeem the maximum possible number
of such shares ratably among the holders of such shares electing to be redeemed
based upon their holdings of Series A Preferred Stock. The shares of Series A
Preferred Stock not redeemed shall remain outstanding and entitled to all the
rights and preferences provided herein. At any time thereafter when additional
funds of the Corporation are legally available for the redemption of shares of
Series A Preferred Stock such funds will immediately be used to redeem the
balance of the shares which the Corporation has become obliged to redeem on any
Redemption Date, but which it has not redeemed.

(d) On or prior to each Redemption Date, the Corporation shall deposit the 
Redemption Price of all shares of Series A Preferred Stock held by 
Shareholders who elect to be redeemed by giving the Redemption Notice and not 
yet redeemed with a bank or trust corporation having aggregate capital and 
surplus 

<PAGE>

in excess of $100,000,000 as a trust fund for the benefit of the respective 
holders of the shares electing redemption and not yet redeemed, with 
irrevocable instructions and authority to the bank or trust corporation to 
pay the Redemption Price for such shares to their respective holders on or 
after the Redemption Date upon receipt of notification from the Corporation 
that such holder has surrendered his share certificate to the Corporation 
pursuant to Section B.3(b) above. As of the Redemption Date, the deposit 
shall constitute full payment for the shares to their holders, and from and 
after the Redemption Date the shares so called for redemption shall be 
redeemed and shall be deemed to be no longer outstanding, and the holders 
thereof shall cease to be shareholders with respect to such shares and shall 
have no rights with respect thereto except the rights to receive from the 
bank or trust corporation payment of the Redemption Price for the shares, 
without interest, upon surrender of their certificates therefor. Such 
instructions shall also provide that any moneys deposited by the Corporation 
pursuant to this Section B.3(d) for the redemption of shares thereafter 
converted into shares of the Corporation's Common Stock pursuant to Section 
B.5 hereof prior to the Redemption Date shall be returned to the Corporation 
forthwith upon such conversion. The balance of any moneys deposited by the 
Corporation pursuant to this Section B.3(d) remaining unclaimed at the 
expiration of two (2) years following the Redemption Date shall thereafter be 
returned to the Corporation upon its request expressed in a resolution of its 
Board of Directors.

           4. VOTING RIGHTS. Except as otherwise expressly provided herein or 
as required by law, the holder of each share of Series A Preferred Stock 
shall be entitled to vote on all matters and shall be entitled to the number 
of votes equal to the largest number of full shares of Common Stock into 
which such shares of Series A Preferred Stock could be converted, pursuant to 
the provisions of Section 5 hereof, at the record date for the determination 
of shareholders entitled to vote on such matters or, if no such record date 
is established, at the date such vote is taken or any written consent of 
shareholders is solicited. Except as otherwise expressly provided herein or 
as required by law, the holders of shares of Series A Preferred Stock and 
holders of Common Stock shall vote together and not as separate classes. Each 
holder of Common Stock shall be entitled to one (1) vote for each share of 
Common Stock held.

           5. CONVERSION. The holders of the Series A Preferred Stock shall 
have the following conversion rights (the "Conversion Rights"):

<PAGE>

(a) RIGHT TO CONVERT. Each share of Series A Preferred Stock shall be 
convertible, at the option of the holder thereof, at any time after the date 
of issuance of such share, with respect to the Series A Preferred Stock, at 
the office of the Corporation or any transfer agent for such stock, into such 
number of fully paid and nonassessable shares of Common Stock as is 
determined by dividing $11.516 by the Conversion Price applicable to such 
share, determined as hereinafter provided, in effect on the date the 
certificate is surrendered for conversion. The price at which shares of 
Common Stock shall be deliverable upon conversion of shares of the Series A 
Preferred Stock (the "Series A Conversion Price") shall initially be $11.516 
per share of Common Stock. Such initial Series A Conversion Price shall be 
adjusted hereinafter provided.

           (b) AUTOMATIC CONVERSION. Each share of the Series A Preferred 
Stock shall automatically be converted into shares of Common Stock at the 
then-effective Series A Conversion Price upon the earlier of (i) immediately 
upon the closing of the sale of the Corporation's Common Stock in a firm 
commitment, underwritten public offering by an underwriter of nationally 
recognized standing registered under the Securities Act of 1933, as amended 
(the "Securities Act"), other than a registration relating solely to a 
transaction under Rule 145 under such Act (or any successor thereto) or to an 
employee benefit plan of the Corporation, at a public offering price (prior 
to underwriters' discounts and expenses) equal to or exceeding $34.55 per 
share of Common Stock (as adjusted for any stock dividends, combinations or 
splits with respect to such shares) and the aggregate proceeds to the 
Corporation and/or any selling shareholders (after deduction for 
underwriters' discounts but excluding expenses relating to the issuance) of 
which exceed $5,000,000; (ii) immediately upon the closing of a Corporate 
Reorganization, as defined in Section B.2(a), at a price per share of Common 
Stock of not less than $23.03 (as adjusted for any stock dividends, 
combinations or splits with respect to such shares), valued as set forth in 
Section 5.(c) below; (iii) after thirty (30) days notice following release of 
audited financial statements by the Corporation for the fiscal year reporting 
at least $2,000,000 in earnings before taxes and before extraordinary items; 
and (iv) pursuant to the provisions set forth in Section B.3(a) above.

           (c) VALUATION OF CONSIDERATION. Whenever the distribution provided 
for in Section B.5(b)(ii) above shall be payable in securities of a 
privately-held corporation or other entity or property other than cash, the 
value of such 

<PAGE>

distribution shall be the fair market value of such securities 
or other property as determined by mutual agreement of a majority of the 
holders of Series A Preferred Stock and the Board of Directors.

(d) MECHANICS OF CONVERSION.

           (1) Before any holder of Series A Preferred Stock shall be 
entitled to voluntarily convert the same into shares of Common Stock, he 
shall surrender the certificate or certificates therefor, duly endorsed, at 
the office of the Corporation or of any transfer agent for the capital stock 
of the Corporation, and shall give written notice to the Corporation at such 
office that he elects to convert the same and shall state therein the number 
of shares of Series A Preferred Stock being converted. Thereupon, the 
Corporation shall as soon as reasonably possible issue and deliver or cause 
to be issued and delivered at such office to such holder of Series A 
Preferred Stock a certificate or certificates for the number of shares of 
Common Stock to which he shall be entitled. Such conversion shall be deemed 
to have been made immediately prior to the close of business on the date of 
such surrender of the shares of Series A Preferred Stock to be converted, and 
the person or persons entitled to receive the shares of Common Stock issuable 
upon such conversion shall be treated for all purposes as the record holder 
or holders of such shares of Common Stock on such date.

           (2) If the conversion is in connection with an underwritten 
offering of securities pursuant to the Securities Act, the conversion may, at 
the option of any holder tendering shares of Series A Preferred Stock for 
conversion, be conditioned upon the closing with the underwriters of the sale 
of securities pursuant to such offering, in which event the person(s) 
entitled to receive the Common Stock upon conversion of the Series A 
Preferred Stock shall not be deemed to have converted such Series A Preferred 
Stock until immediately prior to the closing of such sale of securities.

(e) ADJUSTMENTS TO CONVERSION PRICE FOR STOCK DIVIDENDS AND FOR COMBINATIONS 
OF SUBDIVISIONS OF COMMON STOCK. In the event that this Corporation at any 
time or from time to time after the date the first share of Series A 
Preferred Stock was issued (the "Original Issue Date") shall declare or pay, 
without consideration, any dividend on the Common Stock payable in Common 
Stock or in any right to acquire Common Stock for no consideration, or shall 
effect a subdivision of the outstanding shares of Common Stock into a greater 
number of shares of 

<PAGE>

Common Stock (by stock split, reclassification or otherwise than by payment 
of a dividend in Common Stock or in any right to acquire Common Stock) or in 
the event the outstanding shares of Common Stock shall be combined or 
consolidated, by reclassification or otherwise, into a lesser number of 
shares of Common Stock, then the Conversion Price for the Series A Preferred 
Stock in effect immediately prior to such event shall, concurrently with the 
effectiveness of such event, be proportionately decreased or increased, as 
appropriate. In the event that this Corporation shall declare or pay, without 
consideration, any dividend on the Common Stock payable in any right to 
acquire Common Stock for no consideration, then the Corporation shall be 
deemed to have made a dividend payable in Common Stock in an amount of shares 
equal to the maximum number of shares issuable upon exercise of such rights 
to acquire Common Stock.

           (f) ADJUSTMENTS FOR RECLASSIFICATION AND REORGANIZATION. If the
Common Stock issuable upon conversion of the Series A Preferred Stock shall be
changed into the same or a different number of shares of any other class or
classes of stock, whether by capital reorganization, reclassification or
otherwise (other than a subdivision or combination of shares provided for in
Section B.5(e) above or Corporate Reorganization referred to in Section B.2(a)
above), the Series A Conversion Price then in effect shall, concurrently with
the effectiveness of such reorganization or reclassification, be proportionately
adjusted so that the Series A Preferred Stock shall be convertible into, in lieu
of the number of shares of Common Stock which the holders would otherwise have
been entitled to receive, a number of shares of such other class or classes of
stock equivalent to the number of shares of Common Stock that would have been
subject to receipt by the holders upon conversion of the Series A Preferred
Stock immediately before that change.

           (g) NO IMPAIRMENT. The Corporation will not, by amendment of its
Articles of Incorporation or through any reorganization, transfer of assets,
consolidation, merger, dissolution, issue or sale of securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms to be observed or performed hereunder by the Corporation, but will at
all times in good faith assist in the carrying out of all the provisions of this
Section B.5 and in the taking of all such action as may be necessary or
appropriate in order to protect the Conversion Rights of the holders of the
Series A Preferred Stock against impairment.

<PAGE>

(h) CERTIFICATES OF ADJUSTMENT. Upon the occurrence of each adjustment or
readjustment of any Conversion Price pursuant to this Section B.5, the
Corporation at its expense shall promptly compute such adjustment or
readjustment in accordance with the terms hereof and prepare and furnish to each
holder of Series A Preferred Stock a certificate executed by the Corporation's
President or Chief Financial Officer setting forth such adjustment or
readjustment and showing in detail the facts upon which such adjustment or
readjustment is based. The Corporation shall, upon the written request at any
time of any holder of Series A Preferred Stock, furnish or cause to be furnished
to such holder a like certificate setting forth (i) such adjustments and
readjustments, (ii) the Conversion Price for such Series A Preferred Stock at
the time in effect, and (iii) the number of shares of Common Stock and the
amount, if any, of other property which at the time would be received upon the
conversion of the Series A Preferred stock.

           (i) Notices of Record Date. In the event that the Corporation shall
propose at any time: (i) to declare any dividend or distribution upon its Common
Stock, whether in cash, property, stock or other securities, whether or not a
regular cash dividend and whether or not out of earnings or earned surplus; (ii)
to offer for subscription pro rata to the holders of any class or series of its
stock any additional shares of stock of any class or series or other rights;
(iii) to effect any reclassification or recapitalization of its Common Stock
outstanding involving a change in the Common Stock; or (iv) to effect any
Corporate Reorganization, as defined in Section B.2(a) above, or sell, lease or
convey all or substantially all of its assets, or to liquidate, dissolve or wind
up; then, in connection with each such event, the Corporation shall send to the
holders of Series A Preferred Stock: 

           (1) at least twenty (20) days' prior written notice of the date on
which a record shall be taken for such dividend, distribution or subscription
rights (and specifying the date on which the holders of Common Stock shall be
entitled thereto) or for determining rights to vote, if any, in respect of the
matters referred to in (iii) and (iv) above; and

           (2) in the case of the matters referred to in (iii) and (iv) 
above, at least twenty (20) days' prior written notice of the date when the 
same shall take place (and specifying the date on which the holders of Common 
Stock shall be entitled to exchange their Common Stock for securities or 
other property deliverable upon the occurrence of such event).

<PAGE>

           (j) ISSUE TAXES. The Corporation shall pay any and all issue and
other taxes that may be payable in respect of any issue or delivery of shares of
Common Stock on conversion of Series A Preferred Stock pursuant hereto;
provided, however, that the Corporation shall not be obligated to pay any
transfer taxes resulting from any transfer requested by any holder in connection
with any such conversion.

(k) RESERVATION OF STOCK ISSUABLE UPON CONVERSION. The Corporation shall at all
times reserve and keep available out of its authorized but unissued shares of
Common Stock, solely for the purpose of effecting the conversion of the shares
of the Series A Preferred Stock, such number of its shares of Common Stock as
shall from time to time be sufficient to effect the conversion of all
outstanding shares of the Series A Preferred Stock; and if at any time the
number of authorized but unissued shares of Common Stock shall not be sufficient
to effect the conversion of all then outstanding shares of the Series A
Preferred Stock, the Corporation will take such corporate action as may, in the
opinion of its counsel, be necessary to increase its authorized but unissued
shares of Common Stock to such number of shares as shall be sufficient for such
purpose, including, without limitation, engaging in best efforts to obtain the
requisite shareholder approval of any necessary amendment to these Articles of
Incorporation.

           (l) Fractional Shares. No fractional share shall be issued upon the
conversion of any share or shares of Series A Preferred Stock. All shares of
Common Stock (including fractions thereof) issuable upon conversion of more than
one share of Series A Preferred Stock by a holder thereof shall be aggregated
for purposes of determining whether the conversion would result in the issuance
of any fractional share. If, after the aforementioned aggregation, the
conversion would result in the issuance of a fraction of a share of Common
Stock, the Corporation shall, in lieu of issuing any fractional share, pay the
holder otherwise entitled to such fraction a sum in cash equal to the fair
market value of such fraction on the date of conversion (as determined in good
faith by the Board of Directors).

           (m) NOTICES. Any notice required by the provisions of this Section 
B.5 to be given to the holders of shares of the Series A Preferred Stock 
shall be deemed given when personally delivered to such holder or five (5) 
business days after the same has been deposited in the United States mail, 
certified or registered mail, return receipt requested, postage prepaid, and 

<PAGE>

addressed to each holder of record at its address appearing on the books of 
the Corporation.

           6. Restrictive Covenants. So long as any shares of the Series A
Preferred Stock shall be issued and outstanding, the Corporation shall not,
without first obtaining the approval (by vote or written consent, as provided by
law) of the holders of not less than a majority of the total number of shares of
Series A Preferred Stock then outstanding:

           (a) repurchase any Common Stock or any Series A Preferred Stock other
than pursuant to the provisions set forth in Section B.3 above;
           
           (b) authorize or issue any equity securities with any rights or 
preferences senior to or pari passu with those of the Series A Preferred 
Stock; or

           (c) take any corporate action which materially or adversely affects
the powers, preferences or special rights of the series A Preferred Stock."

           3. Article FIVE of the articles of incorporation of this corporation
is amended to read as follows:

           "FIVE:

           A. The liability of the directors of this corporation for monetary 
damages shall be eliminated to the fullest extent permissible under 
California law.

           B. This corporation is authorized to provide indemnification of 
agents (as defined in section 317 of the California Corporations Code) 
through bylaw provisions, agreements with the agents, vote of shareholders or 
disinterested directors, or otherwise, in excess of the indemnification 
otherwise permitted by section 317 of the California Corporations Code, 
subject only to the applicable limits set forth in section 204 of the 
California Corporations Code with respect to actions for breach of duty to 
the corporation or its shareholders. This corporation is further authorized 
to provide insurance for agents as set forth in section 317 of the California 
Corporations Code, provided that, in cases where this corporation owns all or 
a portion of the shares of the company issuing the insurance policy, the 
company and/or the policy must meet one of the two sets of conditions set 
forth in section 317, as amended.

<PAGE>

           C. Any repeal or modification of the foregoing provisions of this 
Article Five or by the shareholders of this corporation shall not adversely 
affect any right or protection of an agent of this corporation existing at 
the time of such repeal or modification."

           4. The foregoing amendments of articles of incorporation have been 
approved by the Board of Directors of this corporation.

5. The foregoing amendments of articles of incorporation have been approved 
by the required vote of the shareholders of this corporation, in accordance 
with section 902 of the California General Corporation Law; the total number 
of outstanding shares entitled to vote with respect to the foregoing 
amendment was 332,862 shares of Common Stock; and the number of shares of 
Common Stock voting in favor of the foregoing amendment equalled or exceeded 
the vote required, such required vote being a majority of the outstanding 
shares.

           We further declare, under penalty of perjury under the laws of the 
State of California, that the matters set forth in this certificate are true 
and correct of our own knowledge.

                          CERTIFICATE OF AMENDMENT OF
                           ARTICLES OF INCORPORATION
                              OVERLAND DATA INC.

     Scott McClendon and Martin D. Gray certify that: 

     1. They are the President and Secretary, respectively, of Overland Data
Inc. (the "Corporation").

     2. Article FOUR of the articles of incorporation of the Corporation is
amended to read as follows:

     "FOUR:

     A. This Corporation is authorized to issue two classes of shares to be
designated, respectively, Preferred Stock ("Preferred Stock") and Common Stock
("Common Stock").

     The total number of shares of capital stock that the Corporation is
authorized to issue is eight million eight hundred five thousand one hundred and
ninety (8,805,190). The total number of shares of Common Stock this Corporation
shall have the authority to issue is seven million (7,000,000) and the total
number of shares of Preferred Stock this Corporation shall have the authority to
issue is one million eight hundred five thousand one hundred ninety (1,805,190).
The Preferred Stock may be issued in series designated Series A Preferred Stock
and Series B Preferred Stock. The total number of shares of Series A Preferred
Stock this Corporation shall have authority to issue is nine hundred fifty-five
thousand one hundred ninety (955,190). The total number of shares of Series B
Preferred Stock this Corporation shall have authority to issue is eight hundred
fifty thousand (850,000). Upon the amendment of the articles of incorporation of
this Corporation as set forth herein, each outstanding share of the class of
shares previously designated Series A Preferred Stock is converted into and
reconstituted as ten shares of the series of shares designated Series A
Preferred Stock.

     B. The powers, preference, rights, restrictions and other matters relating
to the Preferred Stock are as follows:

          1. DIVIDENDS. No dividend shall be paid on or declared and set apart
for the shares of Common Stock for any dividend period unless at the same time a
like proportionate dividend for the same dividend period, ratably in proportion
to the respective annual dividend rates fixed therefor, shall be paid on or
declared and set apart for the shares of Preferred Stock.

<PAGE>

          2. LIQUIDATION RIGHTS.

                (a) In the event of any liquidation, dissolution, or winding up
of the Corporation, whether voluntary or involuntary, the holders of each share
of Series A Preferred Stock and Series B Preferred Stock then outstanding shall
be entitled to be paid out of the assets of the Corporation available for
distribution to its shareholders, before any payment or declaration and setting
apart for payment of any amount shall be made in respect of the Common Stock, an
amount equal to $1.1516 per share and $1.75 per share, respectively, plus all
declared but unpaid dividends on each share of Series A Preferred Stock and
Series B Preferred Stock, respectively, and no more. If upon liquidation,
dissolution, or winding up of the Corporation, whether voluntary or involuntary,
the assets to be distributed to the holders of the Preferred Stock shall be
insufficient to permit the payment to such shareholders of the full preferential
amount aforesaid, then all of the assets of the Corporation to be distributed
shall be distributed ratably to the holders of the Preferred Stock so that each
holder receives the same percentage of the applicable preferential amount). For
the purposes of this Section B.2(a), any acquisition of the Corporation by means
of merger or other form of corporate reorganization in which outstanding shares
of the Corporation are exchanged for securities or other consideration issued,
or caused to be issued, by the acquiring corporation or its subsidiary (a
"Corporate Reorganization") other than a transaction with a subsidiary of the
Corporation or an entity under common control with the Corporation (and other
than a transaction set forth in Section B.5(b)(ii)) shall be deemed to be a
liquidation, dissolution or winding up of the Corporation.
                
                (b) After the payment or distribution to the holders of the
Preferred Stock of the full preferential amounts aforesaid, the holders of the
Common Stock then outstanding shall be entitled to receive ratably all the
remaining assets of the Corporation.

           3. REDEMPTION.

(a) At the individual option of each holder of shares of Series A Preferred
Stock, the Corporation shall redeem on the sixth, seventh and eighth anniversary
dates from the date of the first issuance of Series A Preferred Stock (each a
"Series A Redemption Date"), at a price per share equal to $1.1516 (as adjusted
for any stock dividends, combinations or splits with respect to such shares)
plus declared but unpaid dividends on such shares (the "Series A Redemption
Price"), at the rate of 33 1/3% of such holders' outstanding shares of Series A
Preferred Stock per year for each of the Series A Redemption Dates. At the
individual option of each 


<PAGE>

holder of shares of Series B Preferred Stock, the Corporation shall redeem on 
December 31, 1996, December 31, 1997 and December 31, 1998 (each a "Series B 
Redemption Date"), at a price per share equal to $1.75 (as adjusted for any 
stock dividends, combinations or splits with respect to such shares) plus 
declared but unpaid dividends on such shares (the "Series B Redemption 
Price"), at the rate of 33 1/3% of such holders' outstanding shares of Series 
B Preferred Stock per year for each of the three Series B Redemption Dates. 
The holders of the Series A Preferred Stock and Series B Preferred Stock will 
give written notice of their election to be redeemed not less than ninety 
(90) days prior to each anniversary date (the "Redemption Notice"). If any 
holders of Series A Preferred Stock or Series B Preferred Stock, as 
applicable, do not timely elect to be redeemed on any of the applicable three 
Redemption Dates, one-third of such holder's shares of Series A Preferred 
Stock or Series B Preferred Stock, as applicable, will automatically be 
converted into Common Stock in accordance with the provisions set forth in 
Section B.5, below, to effect the result that following the last applicable 
Redemption Date all outstanding shares of Series A Preferred Stock and Series 
B Preferred Stock, as applicable, shall either be redeemed or converted into 
common Stock.

               (b) Except as provided in Section B.3(c), on or after each
applicable Redemption Date, each holder of Preferred Stock shall surrender to
this Corporation the certificate or certificates representing the applicable
shares to be redeemed or converted, and thereupon each surrendered certificate
will be canceled and either (i) the appropriate Redemption Price of such shares
shall be payable to the order of the person whose name appears on such
certificate or certificates as the owner thereof, or (ii) the appropriate number
of shares of Common Stock shall be issued for such shares to the owner thereof.
In the event less than all the shares represented by any such certificate are
redeemed or converted into Common Stock, a new certificate shall be issued
representing the unredeemed or unconverted shares.

                (c) From and after each Redemption Date, unless there shall have
been a default in payment of the requested Redemption Price, all rights of the
holders of Preferred Stock (except the right to receive the applicable
Redemption Price without interest or shares of Common Stock upon surrender of
their certificate or certificates) shall cease with respect to such shares, and
such shares shall not thereafter be transferred on the books of the Corporation
or be deemed to be outstanding for any purpose whatsoever. If the funds of the
Corporation legally available for redemption of shares of Series A Preferred
Stock or Series B Preferred Stock on any Redemption Date are insufficient to

<PAGE>

redeem the total number of shares of Series A Preferred Stock or Series B
Preferred Stock to be redeemed on such date, those funds which are legally
available will be used to redeem the maximum possible number of such shares
ratably among the holders of such shares electing to be redeemed based upon
their holdings of Series A Preferred Stock or Series B Preferred Stock, as
applicable. The shares of Series A Preferred Stock and Series B Preferred Stock
not redeemed shall remain outstanding and entitled to all the rights and
preferences provided herein. At any time thereafter when additional funds of the
Corporation are legally available for the redemption of shares of Series A
Preferred Stock or Series B Preferred Stock, as applicable, such funds will
immediately be used to redeem ratably the balance of the shares which the
Corporation has become obliged to redeem on any Redemption Date, but which it
has not redeemed.

               (d) On or prior to each Redemption Date, the Corporation shall
deposit the Redemption Price of all shares of the applicable series of Preferred
Stock held by Shareholders who elect to be redeemed by giving the Redemption
Notice and not yet redeemed with a bank or trust corporation having aggregate
capital and surplus in excess of $100,000,000 as a trust fund for the benefit of
the respective holders of the shares electing redemption and not yet redeemed,
with irrevocable instructions and authority to the bank or trust corporation to
pay the applicable Redemption Price for such shares to their respective holders
on or after such Redemption Date upon receipt of notification from the
Corporation that such holder has surrendered his share certificate to the
Corporation pursuant to Section B.3(b) above. As of such Redemption Date, the
deposit shall constitute full payment for the shares to their holders, and from
and after such Redemption Date the shares so called for redemption shall be
redeemed and shall be deemed to be no longer outstanding, and the holders
thereof shall cease to be shareholders with respect to such shares and shall
have no rights with respect thereto except the rights to receive from the bank
or trust corporation payment of the applicable Redemption Price for the shares,
without interest, upon surrender of their certificates therefor. Such
instructions shall also provide that any moneys deposited by the Corporation
pursuant to this Section B.3(d) for the redemption of shares thereafter
converted into shares of the Corporation's Common Stock pursuant to Section B.5
hereof prior to the applicable Redemption Date shall be returned to the
Corporation forthwith upon such conversion. The balance of any moneys deposited
by the Corporation pursuant to this Section B.3(d) remaining unclaimed at the
expiration of two (2) years following the applicable Redemption Date shall
thereafter be returned to the Corporation upon its request expressed in a
resolution of its Board of Directors.

<PAGE>

           4. VOTING RIGHTS. Except as otherwise expressly provided herein or as
required by law, each holder of shares of Preferred Stock shall be entitled to
vote on all matters and shall be entitled to the number of votes equal to the
largest number of full shares of Common Stock into which such shares of
Preferred Stock could be converted. pursuant to the provisions of Section 5
hereof, at the record date for the determination of shareholders entitled to
vote on such matters or, if no such record date is established, at the date such
vote is taken or any written consent of shareholders is solicited. Except as
otherwise expressly provided herein or as required by law, the holders of shares
of Preferred Stock and holders of Common Stock shall vote together and not as
separate classes. Each holder of Common Stock shall be entitled to one (1) vote
for each share of Common Stock held.

          5. CONVERSION. The holders of the Preferred Stock shall have the
following conversion rights (the "Conversion Rights"):

                (a) RIGHT TO CONVERT. Each share of Series A Preferred Stock and
Series B Preferred Stock shall be convertible, at the option of the holder
thereof, at any time after the date of issuance of such share, at the office of
the Corporation or any transfer agent for such stock, into such number of fully
paid and nonassessable shares of Common Stock as is determined by dividing
$1.1516 and $1.75, respectively, by the Conversion Price applicable to the
shares of Series A Preferred Stock and Series B Preferred Stock, respectively,
determined as hereinafter provided, in effect on the date the certificate is
surrendered for conversion. The price at which shares of Common Stock shall be
deliverable upon conversion of shares of the Series A Preferred Stock (the
"Series A Conversion Price") and the Series B Preferred Stock (the "Series B
Conversion Price") shall initially be $1.1516 and $1.75 per share of Common
Stock, respectively. Such initial Series A Conversion Price and Series B
Conversion Price (collectively, the "Conversion Prices") shall be adjusted as
hereinafter provided.

                (b) AUTOMATIC CONVERSION. Each share of the Preferred Stock 
shall automatically be converted into shares of Common Stock at the 
then-effective applicable Conversion Price upon the earlier of (i) 
immediately upon the closing of the sale of the Corporation's Common Stock in 
a firm commitment, underwritten public offering by an underwriter of 
nationally recognized standing registered under the Securities Act of 1933, 
as amended (the "Securities Act"), other than a registration relating solely 
to a transaction under Rule 145 under such Act (or any successor thereto) or 
to an employee benefit plan of the Corporation, at a public offering price 
(prior to underwriters' discounts and expenses) equal to or exceeding $4.00 
per share of Common Stock (as adjusted for any 

<PAGE>

stock dividends, combinations or splits with respect to such shares) and the 
aggregate proceeds to the Corporation and/or any selling shareholders (after 
deduction for underwriters' discounts but excluding expenses relating to the 
issuance) of which exceed $5,000,000; (ii) immediately upon the closing of a 
merger, reorganization, sale of control, or any transaction in which all or 
substantially all of the assets of the Company are sold (other than a merger 
into a wholly-owned subsidiary), and in which the aggregate net proceeds 
available for distribution to shareholders of the Corporation (exclusive of 
commission and other payments and expenses) per share of Common Stock issued 
or issuable upon conversion of outstanding convertible securities or upon 
exercise of outstanding warrants and options is not less than $4.00 (as 
adjusted for any stock dividends, combinations or splits with respect to such 
shares), valued as set forth in Section B.5(c) below; and (iii) after 
thirty(30) days' notice following release of audited financial statements by 
the Corporation for the first fiscal year in which the Corporation reports at 
least $7,000,000 in earnings before taxes and before extraordinary items; and 
(iv) pursuant to the provisions set forth in Section B.3(a) above.

                (c) VALUATION OF CONSIDERATION. Whenever a transaction described
in Section B.5(b)(ii) above shall provide for payment in securities of a
privately-held corporation or other entity or property other than cash, the
value of such securities or other property shall be deemed to be the fair market
value of such securities or other property as determined by mutual agreement of
a majority of the holders of Series A Preferred Stock, a majority of the holders
of Series B Preferred Stock and the Board of Directors of the Corporation.

                (d) MECHANICS OF CONVERSION.

                     (i) Before any holder of Preferred Stock shall be entitled
to voluntarily convert the same into shares of Common Stock, he shall surrender
the certificate or certificates therefor, duly endorsed, at the office of the
Corporation or of any transfer agent for the capital stock of the Corporation,
and shall give written notice to the Corporation at such office that he elects
to convert the same and shall state therein the number of shares of Preferred
Stock being converted. Thereupon, the Corporation shall as soon as reasonably
possible issue and deliver or cause to be issued and delivered at such office to
such holder of Preferred Stock a certificate or certificates for the number of
shares of Common Stock to which he shall be entitled. Such conversion shall be
deemed to have been made immediately prior to the close of business on the date
of such surrender of the shares of Preferred Stock to be converted, and the
person or persons entitled to 

<PAGE>

receive the shares of Common Stock issuable upon such conversion shall be 
treated for all purposes as the record holder or holders of such shares of 
Common Stock on such date.

                     (ii) If the conversion is in connection with an
underwritten offering of securities pursuant to the Securities Act, the
conversion may, at the option of any holder tendering shares of Preferred Stock
for conversion, be conditioned upon the closing with the underwriters of the
sale of securities pursuant to such offering, in which event the person(s)
entitled to receive the Common Stock upon conversion of the Preferred Stock
shall not be deemed to have converted such Preferred Stock until immediately
prior to the closing of such sale of securities.

                (e) ADJUSTMENTS TO CONVERSION PRICE FOR STOCK DIVIDENDS AND FOR
COMBINATIONS OR SUBDIVISIONS OF COMMON STOCK. In the event that this Corporation
at any time or from time to time after the date the first share of Series B
Preferred Stock was issued (the "Original Issue Date") shall declare or pay,
without consideration, any dividend on the Common Stock payable in Common Stock
or in any right to acquire Common Stock for no consideration, or shall effect a
subdivision of the outstanding shares of Common Stock into a greater number of
shares of Common Stock (by stock split, reclassification or otherwise than by
payment of a dividend in Common Stock or in any right to acquire Common Stock)
or in the event the outstanding shares of Common Stock shall be combined or
consolidated, by reclassification or otherwise, into a lesser number of shares
of Common Stock, then the Conversion Price for each series of Preferred Stock in
effect immediately prior to such event shall, concurrently with the
effectiveness of such event, be proportionately decreased or increased, as
appropriate. In the event that this Corporation shall declare or pay, without
consideration, any dividend on the Common Stock payable in any right to acquire
Common Stock for no consideration, then the Corporation shall be deemed to have
made a dividend payable in Common Stock in an amount of shares equal to the
maximum number of shares issuable upon exercise of such rights to acquire Common
Stock.

                (f) ADJUSTMENTS FOR RECLASSIFICATION AND REORGANIZATION. If the
Common Stock issuable upon conversion of the Preferred Stock shall be changed
into the same or a different number of shares of any other class or classes of
stock, whether by capital reorganization, reclassification or otherwise (other
than a subdivision or combination of shares provided for in Section B.5(e) above
or Corporate Reorganization referred to in Section B.2 (a) above), the
applicable Conversion Price for each series of Preferred Stock then in effect
shall, concurrently with the 

<PAGE>

effectiveness of such reorganization or reclassification, be proportionately 
adjusted so that the Preferred Stock shall be convertible into, in lieu of 
the number of shares of Common Stock which the holders would otherwise have 
been entitled to receive, a number of shares of such other class or classes 
of stock equivalent to the number of shares of Common Stock that would have 
been subject to receipt by the holders upon conversion of the Preferred Stock 
immediately before that change.

                (g) NO IMPAIRMENT. The Corporation will not, by amendment of 
its Articles of Incorporation or through any reorganization, transfer of 
assets, consolidation, merger, dissolution, issue or sale of securities or 
any other voluntary action, avoid or seek to avoid the observance or 
performance of any of the terms to be observed or performed hereunder by the 
Corporation, but will at all times in good faith assist in the carrying out 
of all the provisions of this Section B.5 and in the taking of all such 
action as may be necessary or appropriate in order to protect the Conversion 
Rights of the holders of the Preferred Stock against impairment.

                (h) CERTIFICATES OF ADJUSTMENT. Upon the occurrence of each
adjustment or readjustment of any Conversion Price pursuant to this Section B.5,
the Corporation at its expense shall promptly compute such adjustment or
readjustment in accordance with the terms hereof and prepare and furnish to each
holder of Preferred Stock a certificate executed by the Corporation's President
or Chief Financial Officer setting forth such adjustment or readjustment and
showing in detail the facts upon which such adjustment or readjustment is based.
The Corporation shall, upon the written request at any time of any holder of
Preferred Stock, furnish or cause to be furnished to such holder a like
certificate setting forth (i) such adjustments and readjustments, (ii) the
Conversion Price for such Preferred Stock at the time in effect, and (iii) the
number of shares of Common Stock and the amount, if any, of other property which
at the time would be received upon the conversion of such Preferred Stock .

                (i) NOTICES OF RECORD DATE. In the event that the Corporation
shall propose at any time: (i) to declare any dividend or distribution upon its
Common Stock, whether in cash, property, stock or other securities, whether or
not a regular cash dividend and whether or not out of earnings or earned
surplus; (ii) to offer for subscription pro rata to the holders of any class or
series of its stock any additional shares of stock of any class or series or
other rights; (iii) to effect any reclassification or recapitalization of its
Common Stock outstanding involving a change in the Common stock; or (iv) to
effect any Corporate 

<PAGE>

Reorganization, as defined in Section B.2(a) above, or sell, lease or convey 
all or substantially all of its assets, or to liquidate, dissolve or wind up; 
then, in connection with each such event, the Corporation shall send to the 
holders of Preferred Stock:

               (1) at least twenty (20) days' prior written notice of the date
on which a record shall be taken for such dividend, distribution or subscription
rights (and specifying the date on which the holders of Common Stock shall be
entitled thereto) or for determining rights to vote, if any, in respect of the
matters referred to in (iii) and (iv) above; and

               (2) in the case of the matters referred to in (iii) and (iv)
above, at least twenty (20) days' prior written notice of the date when the same
shall take place (and specifying the date on which the holders of Common Stock
shall be entitled to exchange their Common Stock for securities or other
property deliverable upon the occurrence of such event).

               (j) ISSUE TAXES. The Corporation shall pay any and all issue and
other taxes that may be payable in respect of any issue or delivery of shares of
Common Stock on conversion of Preferred Stock pursuant hereto; provided,
however, that the Corporation shall not be obligated to pay any transfer taxes
resulting from any transfer requested by any holder in connection with any such
conversion.

               (k) RESERVATION OF STOCK ISSUABLE UPON CONVERSION. The
Corporation shall at all times reserve and keep available out of its authorized
but unissued shares of Common Stock, solely for the purpose of effecting the
conversion of the shares of the Preferred Stock, such number of its shares of
Common Stock as shall from time to time be sufficient to effect the conversion
of all outstanding shares of the Preferred Stock; and if at any time the number
of authorized but unissued shares of Common Stock shall not be sufficient to
effect the conversion of all then outstanding shares of the Preferred Stock, the
Corporation will take such corporate action as may, in the opinion of its
counsel, be necessary to increase its authorized but unissued shares of Common
Stock to such number of shares as shall be sufficient for such purpose,
including, without limitation, engaging in best efforts to obtain the requisite
shareholder approval of any necessary amendment to these Articles of
Incorporation.

               (l) FRACTIONAL SHARES. No fractional share shall be issued upon
the conversion of any share of Preferred Stock. All shares of Common Stock
(including fractions thereof) issuable upon conversion of more than one share of
a series of Preferred Stock by 

<PAGE>

a holder thereof shall be aggregated for purposes of determining whether the 
conversion would result in the issuance of any fractional share. If, after 
the aforementioned aggregation, the conversion would result in the issuance 
of a fraction of a share of Common Stock, the Corporation shall, in lieu of 
issuing any fractional shares, pay the holder otherwise entitled to such 
fraction a sum in cash equal to the fair market value of such fraction on the 
date of conversion (as determined in good faith by the Board of Directors).

                (m) NOTICES. Any notice required by the provisions of this
Section B.5 to be given to a holder of Preferred Stock shall be deemed given
when personally delivered to such holder or five (5) business days after the
same has been deposited in the United States mail, certified or registered mail,
return receipt requested, postage prepaid, and addressed to such holder at its
address appearing on the books of the Corporation.

          6. SERIES A RESTRICTIVE COVENANTS. So long as any shares of the Series
A Preferred Stock shall be issued and outstanding, the Corporation shall not,
without first obtaining the approval (by vote or written consent, as provided by
law) of the holders of not less than a majority of the total number of shares of
Series A Preferred Stock then outstanding:

                (a) repurchase any Common Stock or any Preferred Stock other
than pursuant to the provisions set forth in Section B.3 above;

                (b) authorize or issue any equity securities with any rights or
preferences senior to or pari passu with those of the Series A Preferred Stock;
or

                (c) take any corporate action which materially or adversely
affects the powers, preferences or special rights of the .C Pr; m;: A Preferred
Stock.

          7. SERIES B RESTRICTIVE COVENANTS. So long as any shares of the Series
B Preferred Stock shall be issued and outstanding, the Corporation shall not,
without first obtaining the approval (by vote or written consent, as provided by
law) of the holders of not less than a majority of the total number of shares of
Series B Preferred Stock then outstanding:

                (a) repurchase any Common Stock or any Preferred Stock other
than pursuant to the provisions set forth in Section B.3 above;

<PAGE>

                (b) authorize or issue any equity securities with any rights or
preferences senior to or pari passu with those of the Series B Preferred Stock;
or

                (c) take any corporate action which materially or adversely
affects the powers, preferences or special rights of the Series B Preferred
Stock.

     3. The foregoing amendments of articles of incorporation have been approved
by the Board of Directors of this corporation.

     4. The foregoing amendments of articles of incorporation have been approved
by the required vote of the shareholders of this corporation, in accordance with
section 902 of the California General Corporation Law; the total number of
outstanding shares entitled to vote with respect to the foregoing amendment was
3,446,580 shares of Common Stock and 95,519 shares of Series A Preferred Stock;
and the number of shares voting in favor of the foregoing amendment equalled or
exceeded the vote required, such required vote being a majority of the
outstanding shares of Common Stock and a majority of the outstanding shares of
Series A Preferred Stock.

          We further declare, under penalty of perjury under the laws of the
State California, that the matters set forth in this certificate are true and
correct of our own knowledge.

                         CERTIFICATE OF AMENDMENT OF
                          ARTICLES OF INCORPORATION
                                     OF
                             OVERLAND DATA INC.

     Scott McClendon and Martin D. Gray certify that:

     1. They are the President and Secretary, respectively, of Overland Data
Inc. (the "Corporation").

     2. Article FOUR of the articles of incorporation of the Corporation is
amended to read as follows:

     "FOUR:

     A. This Corporation is authorized to issue two classes of shares to be
designated, respectively, Preferred Stock ("Preferred Stock") and Common Stock
("Common Stock").

          The total number of shares of capital stock that the Corporation is
authorized to issue is twelve million ninety-nine thousand one hundred one
(12,099,101). The total number of shares of Common Stock this Corporation shall
have the authority to issue is nine million (9,000,000) and the total number of
shares of Preferred Stock this Corporation shall have the authority to issue is
three million ninety-nine thousand one hundred one (3,099,101). The Preferred
Stock may be issued in series designated Series A Preferred Stock, Series B
Preferred Stock and Series C Preferred Stock. The total number of shares of
Series A Preferred Stock this Corporation shall have authority to issue is nine
hundred fifty-five thousand one hundred ninety (955,190). The total number of
shares of Series B Preferred Stock this Corporation shall have authority to
issue is seven hundred thirty-one thousand four hundred twenty-nine (731,429).
The total number of shares of Series C Preferred Stock that this Corporation
shall have authority to issue is one million four hundred twelve thousand four
hundred eighty-two (1,412,482)

     B. The powers, preference, rights, restrictions and other matters relating
to the Preferred Stock are as follows:

          1. DIVIDENDS. No dividend shall be paid on or declared and set apart
for the shares of Common Stock for any dividend period unless at the same time a
like proportionate dividend for the same dividend period, ratably in proportion
to the respective annual dividend rates fixed therefor, shall be paid on or
declared and set apart for the shares of Preferred Stock.

<PAGE>

2. LIQUIDATION RIGHTS.

                (a) In the event of any liquidation, dissolution, or winding 
up of the Corporation, whether voluntary or involuntary, the holders of each 
share of Series A Preferred Stock, Series B Preferred Stock and Series C 
Preferred Stock then outstanding shall be entitled to be paid out of the 
assets of the Corporation available for distribution to its shareholders, 
before any payment or declaration and setting apart for payment of any amount 
shall be made in respect of the Common Stock, an amount equal to (i) $1.1516 
per share of Series A Preferred Stock, plus all declared and unpaid dividends 
on each share of Series A Preferred Stock, and no more, (ii) $1.75 per share 
of Series B Preferred Stock, plus all declared and unpaid dividends on each 
share of Series B Preferred Stock, and no more, and (iii) $2.7611 per share 
of Series C Preferred Stock, plus all declared and unpaid dividends on each 
share of Series C Preferred Stock, and no more. If upon liquidation, 
dissolution, or winding up of the Corporation, whether voluntary or 
involuntary, the assets to be distributed to the holders of the Preferred 
Stock shall be insufficient to permit the payment to such shareholders of the 
full preferential amount aforesaid, then all of the assets of the Corporation 
to be distributed shall be distributed ratably to the holders of the 
Preferred Stock (so that each holder receives the same percentage of the 
applicable preferential amount). For the purposes of this Section B.2(a), any 
acquisition of the Corporation by means of merger or other form of corporate 
reorganization in which outstanding shares of the Corporation are exchanged 
for securities or other consideration issued, or caused to be issued, by the 
acquiring corporation or its subsidiary (a "Corporate Reorganization") other 
than a transaction with a subsidiary of the Corporation or an entity under 
common control with the Corporation (and other than a transaction set forth 
in Section B.5(b)(ii)) shall be deemed to be a liquidation, dissolution or 
winding up of the Corporation.

               (b) After the payment or distribution to the holders of the
Preferred Stock of the full preferential amounts aforesaid, the holders of the
Common Stock then outstanding shall be entitled to receive ratably all the
remaining assets of the Corporation.

     3. REDEMPTION.

                (a) At the individual option of each holder of shares of Series
A Preferred Stock, the Corporation shall redeem on the sixth (the "First Series
A Redemption Date"), seventh (the Second Series A Redemption Date") and eighth
(the "Third Series A Redemption Date") anniversary dates from the date of the
first issuance of Series A Preferred Stock, at a price per share equal to
$1.1516 (as adjusted for any stock dividends, combinations or splits with
respect 

<PAGE>

to such shares) plus declared but unpaid dividends on such shares (the
"Series A Redemption Price"), at the rate of 33 1/3% of such holders' then
outstanding shares of Series A Preferred Stock at the First Series A Redemption
Date, 50% of such holders' then outstanding shares of Series A Preferred Stock
at the Second Series A Redemption Date, and 100% of such holders' then
outstanding shares of Series A Preferred Stock at the Third Series A Redemption
Date. At the individual option of each holder of shares of Series B Preferred
Stock, the Corporation shall redeem on December 31, 1996 (the "First Series B
Redemption Date"), December 31, 1997 (the "Second Series B Redemption Date") and
December 31, 1998 (the "Third Series B Redemption Date"), at a price per share
equal to $1.75 (as adjusted for any stock dividends, combinations or splits with
respect to such shares) plus declared but unpaid dividends on such shares (the
"Series B Redemption Price"), at the rate of 33 1/3% of such holders' then
outstanding shares of Series B Preferred Stock at the First Series B Redemption
Date, 50% of such holders' then outstanding shares of Series B Preferred Stock
at the Second Series B Redemption Date and 100% of such holders' then
outstanding shares of Series B Preferred Stock at the Third Series B Redemption
Date. At the individual option of each holder of shares of Series C Preferred
Stock, the Corporation shall redeem on May 31, 1997 (the "First Series C
Redemption Date"), May 31, 1998 (the "Second Series C Redemption Date") and May
31, 1999 (the "Third Series C Redemption Date"), at a price per share equal to
$2.7611 (as adjusted for any stock dividends, combinations or splits with
respect to such shares) plus declared but unpaid dividends on such shares (the
"Series C Redemption Price"), at the rate of 33 1/3% of such holders' then
outstanding shares of Series C Preferred Stock at the First Series C Redemption
Date, 50% of such holders' then outstanding shares of Series C Preferred Stock
at the Second Series C Redemption Date, and 100% of such holders' then
outstanding shares at the Third Series C Redemption Date. The holders of the
Series A Preferred Stock, Series B Preferred Stock and Series C Preferred Stock
will give written notice of their election to be redeemed not less than ninety
(90) days prior to a Redemption Date applicable to such series of Preferred
Stock (the "Redemption Notice"). If any holder of Series A Preferred Stock,
Series B Preferred Stock or Series C Preferred Stock, as applicable, does not
timely elect to be redeemed on any of the applicable three Redemption Dates, the
number of such holder's shares of Series A Preferred Stock, Series B Preferred
Stock or Series C Preferred Stock, as applicable, which would otherwise be
redeemed on the applicable Redemption Date will automatically be converted into
Common Stock in accordance with the provisions set forth in Section B.5, below,
to effect the result that following the last applicable Redemption Date all
outstanding shares of Series A Preferred Stock, Series B Preferred Stock and
Series C Preferred 

<PAGE>

Stock, as applicable, shall either be redeemed or converted into Common Stock.

                (b) Except as provided in Section B.3(c), on or after each
applicable Redemption Date, each holder of Preferred Stock shall surrender to
this Corporation the certificate or certificates representing the applicable
shares to be redeemed or converted, and thereupon each surrendered certificate
will be canceled and either (i) the appropriate Redemption Price of such shares
shall be payable to the order of the person whose name appears on such
certificate or certificates as the owner thereof, or (ii) the appropriate number
of shares of Common Stock shall be issued for such shares to the owner thereof.
In the event less than all the shares represented by any such certificate are
redeemed or converted into Common Stock, a new certificate shall be issued
representing the unredeemed or unconverted shares.

               (c) From and after each Redemption Date, unless there shall have
been a default in payment of the requested Redemption Price, all rights of the
holders of Preferred Stock (except the right to receive the applicable
Redemption Price without interest or shares of Common Stock upon surrender of
their certificate or certificates) shall cease with respect to such shares, and
such shares shall not thereafter be transferred on the books of the Corporation
or be deemed to be outstanding for any purpose whatsoever. If the funds of the
Corporation legally available for redemption of shares of Series A Preferred
Stock, Series B Preferred Stock or Series C Preferred Stock on any Redemption
Date are insufficient to redeem the total number of shares of Series A Preferred
Stock, Series B Preferred Stock and Series C Preferred Stock to be redeemed on
such date, those funds which are legally available will be used to redeem the
maximum possible number of such shares ratably among the holders of such shares
electing to be redeemed based upon their holdings of Series A Preferred Stock,
Series B Preferred Stock and Series C Preferred Stock, as applicable. The shares
of Series A Preferred Stock, Series B Preferred Stock and Series C Preferred
Stock not redeemed shall remain outstanding and entitled to all the rights and
preferences provided herein. At any time thereafter when additional funds of the
Corporation are legally available for the redemption of shares of Series A
Preferred Stock, Series B Preferred Stock and Series C Preferred Stock, as
applicable, such funds will immediately be used to redeem ratably the balance of
the shares which the Corporation has become obliged to redeem on any Redemption
Date, but which it has not redeemed.

                (d) On or prior to each Redemption Date, the Corporation shall
deposit the Redemption Price of all shares of the applicable series of Preferred
Stock held by shareholders who elect 

<PAGE>

to be redeemed by giving the Redemption Notice and not yet redeemed with a 
bank or trust corporation having aggregate capital and surplus in excess of 
$100,000,000 as a trust fund for the benefit of the respective holders of the 
shares electing redemption and not yet redeemed, with irrevocable 
instructions and authority to the bank or trust corporation to pay the 
applicable Redemption Price for such shares to their respective holders on or 
after such Redemption Date upon receipt of notification from the Corporation 
that such holder has surrendered his share certificate to the Corporation 
pursuant to Section B.3(b) above. As of such Redemption Date, the deposit 
shall constitute full payment for the shares to their holders, and from and 
after such Redemption Date the shares so called for redemption shall be 
redeemed and shall be deemed to be no longer outstanding, and the holders 
thereof shall cease to be shareholders with respect to such shares and shall 
have no rights with respect thereto except the rights to receive from the 
bank or trust corporation payment of the applicable Redemption Price for the 
shares, without interest, upon surrender of their certificates therefor. Such 
instructions shall also provide that any moneys deposited by the Corporation 
pursuant to this Section B.3 (d) for the redemption of shares thereafter 
converted into shares of the Corporation's Common Stock pursuant to Section 
B.5 hereof prior to the applicable Redemption Date shall be returned to the 
Corporation forthwith upon such conversion. The balance of any moneys 
deposited by the Corporation pursuant to this Section B.3(d) remaining 
unclaimed at the expiration of two (2) years following the applicable 
Redemption Date shall thereafter be returned to the Corporation upon its 
request expressed in a resolution of its Board of Directors.

          4. VOTING RIGHTS.

                (a) GENERAL. Except as otherwise expressly provided herein or as
required by law, each holder of shares of Preferred Stock shall be entitled to
vote on all matters and shall be entitled to the number of votes equal to the
largest number of full shares of Common Stock into which such shares of
Preferred Stock could be converted, pursuant to the provisions of Section B.5
hereof, at the record date for the determination of shareholders entitled to
vote on such matters or, if no such record date is established, at the date such
vote is taken or any written consent of shareholders is solicited. Except as
otherwise expressly provided herein or as required by law, the holders of shares
of Preferred Stock and holders of Common Stock shall vote together and not as
separate classes. Each holder of Common Stock shall be entitled to one (1) vote
for each share of Common stock held. 

                (b) DIRECTORS. The holders of the Series A Preferred Stock,
voting separately as a class, shall be entitled to elect one 

<PAGE>

(1) member of the Board of Directors of this Corporation. The holders of the 
Series B Preferred Stock, voting separately as a class, shall be entitled to 
elect one (1) member of the Board of Directors of this Corporation. The 
holders of the Series C Preferred Stock, voting separately as a class, shall 
be entitled to elect one (1) member of the Board of Directors of this 
Corporation. The holders of the Common Stock, voting separately from all 
other classes and series, shall be entitled to elect the remaining members of 
the Board of Directors of this Corporation. In the case of any vacancy in the 
office of a director elected by the holders of a particular class or series 
of stock, such vacancy may be filled only by the vote of the holders of such 
class or series of stock. Any director who shall have been elected by the 
holders of a particular class or series of stock may be removed without cause 
by, and only by, the applicable vote of the holders of such class or series 
of stock

          5. CONVERSION. The holders of the Preferred Stock shall have the
following conversion rights (the "Conversion Rights"):

                (a) RIGHT TO CONVERT. Each share of Series A Preferred Stock,
Series B Preferred Stock and Series C Preferred Stock shall be convertible, at
the option of the holder thereof, at any time after the date of issuance of such
share, at the office of the Corporation or any transfer agent for such stock,
into such number of fully paid and nonassessable shares of Common Stock as is
determined by dividing $1.1516, $1.75 and $2.7611, respectively, by the
Conversion Price applicable to the shares of Series A Preferred Stock, Series B
Preferred Stock and Series C Preferred Stock, respectively, determined as
hereinafter provided, in effect on the date the certificate is surrendered for
conversion. The price at which shares of Common Stock shall be deliverable upon
conversion of shares of the Series A Preferred Stock (the "Series A Conversion
Price"), the Series B Preferred Stock (the "Series B Conversion Price") and
Series C Preferred Stock (the "Series C Conversion Price") shall initially be
$1.1516, $1.75 and $2.7611 per share of Common Stock, respectively. Such initial
Series A Conversion Price, Series B Conversion Price and Series C Conversion
Price (collectively, the "Conversion Prices") shall be adjusted as hereinafter
Provided.

                (b) AUTOMATIC CONVERSION. Each share of the Preferred Stock
shall automatically be converted into shares of Common Stock at the
then-effective applicable Conversion Price upon the earliest of (i) immediately
upon the closing of the sale of the Corporation's Common Stock in a firm
commitment, underwritten public offering by an underwriter of nationally
recognized standing registered under the Securities Act of 1933, as amended (the
"Securities Act"), other than a registration relating solely to a transaction
under Rule 145 under 

<PAGE>

such Act (or any successor thereto) or to an employee benefit plan of the 
Corporation, at a public offering price (prior to underwriters' discounts and 
expenses) equal to or exceeding $4.00 per share of Common Stock (as adjusted 
for any stock dividends, combinations or splits with respect to such shares) 
and the aggregate proceeds to the Corporation and/or any selling shareholders 
(after deduction for underwriters' discounts but excluding expenses relating 
to the issuance) of which exceed $5,000,000; (ii) immediately upon the 
closing of a merger, reorganization, sale of control, or any transaction in 
which all or substantially all of the assets of the Company are sold (other 
than a merger into a wholly-owned subsidiary or any other merger or 
consolidation in which the holders of equity securities of the Corporation 
immediately prior thereto hold a majority of the voting securities of the 
surviving corporation immediately thereafter), and in which the aggregate net 
proceeds available for distribution to shareholders of the Corporation 
(exclusive of commission and other payments and expenses) per share of Common 
Stock issued or issuable upon conversion of outstanding convertible 
securities or upon exercise of outstanding warrants and options is not less 
than $4.00 (as adjusted for any stock dividends, combinations or splits with 
respect to such shares), valued as set forth in Section B.5(c) below; (iii) 
after thirty (30) days' notice following release of audited financial 
statements by the Corporation for the first fiscal year in which the 
Corporation reports at least $7,000,000 in earnings before taxes and before 
extraordinary items; or (iv) pursuant to the provisions set forth in Section 
B.3 (a) above.

                (c) VALUATION OF CONSIDERATION. Whenever a transaction described
in Section B.5(b)(ii) above shall provide for payment in securities of a
privately-held corporation or other entity or property other than cash, the
value of such securities or other property shall be deemed to be the fair market
value of such securities or other property as determined by mutual agreement of
the holders of a majority of the Series A Preferred Stock, the holders of a
majority of the Series B Preferred Stock, and the holders of a majority of the
Series C Preferred Stock and the Board of Directors of the Corporation.

                (d) MECHANICS OF CONVERSION.

                     (i) Before any holder of Preferred Stock shall be entitled
to voluntarily convert the same into shares of Common Stock, he shall surrender
the certificate or certificates therefor, duly endorsed, at the office of the
Corporation or of any transfer agent for the capital stock of the Corporation,
and shall give written notice to the Corporation at such office that he elects
to convert the same and shall state therein the number of shares of Preferred

<PAGE>

Stock being converted. Thereupon, the Corporation shall as soon as reasonably
possible issue and deliver or cause to be issued and delivered at such office to
such holder of Preferred Stock a certificate or certificates for the number of
shares of Common Stock to which he shall be entitled. Such conversion shall be
deemed to have been made immediately prior to the close of business on the date
of such surrender of the shares of Preferred Stock to be converted, and the
person or persons entitled to receive the shares of Common Stock issuable upon
such conversion shall be treated for all purposes as the record holder or
holders of such shares of Common Stock on such date.

                     (ii) If the conversion is in connection with an
underwritten offering of securities pursuant to the Securities Act, the
conversion may, at the option of any holder tenderinq shares of Preferred Stock
for conversion, be conditioned upon the closing with the underwriters of the
sale of securities pursuant to such offering, in which event the person(s)
entitled to receive the Common Stock upon conversion of the Preferred Stock
shall not be deemed to have converted such Preferred Stock until immediately
prior to the closing of such sale of securities.

                (e) ADJUSTMENTS TO CONVERSION PRICE FOR STOCK DIVIDENDS AND FOR
COMBINATIONS OR SUBDIVISIONS OF COMMON STOCK. In the event that this Corporation
at any time or from time to time after the date the first share of Series C
Preferred Stock was issued (the "Original Issue Date") shall declare or pay,
without consideration, any dividend on the Common Stock payable in Common Stock
or in any right to acquire Common Stock for no consideration, or shall effect a
subdivision of the outstanding shares of Common Stock into a greater number of
shares of Common Stock (by stock split, reclassification or otherwise than by
payment of a dividend in Common Stock or in any right to acquire Common Stock)
or in the event the outstanding shares of Common Stock shall be combined or
consolidated, by reclassification or otherwise, into a lesser number of shares
of Common Stock, then the Conversion Price for each series of Preferred Stock in
effect immediately prior to such event shall, concurrently with the
effectiveness of such event, be proportionately decreased or increased, as
appropriate. In the event that this Corporation shall declare or pay, without
consideration, any dividend on the Common Stock payable in any right to acquire
Common Stock for no consideration, then the Corporation shall be deemed to have
made a dividend payable in Common Stock in an amount of shares equal to the
maximum number of shares issuable upon exercise of such rights to acquire Common
Stock.

<PAGE>

                (f) ADJUSTMENTS FOR RECLASSIFICATION AND REORGANIZATION. If the
Common Stock issuable upon conversion of the Preferred Stock shall be changed
into the same or a different number of shares of any other class or classes of
stock, whether by capital reorganization, reclassification or otherwise (other
than a subdivision or combination of shares provided for in Section B.5(e) above
or Corporate Reorganization referred to in Section B.2(a) above), the applicable
Conversion Price for each series of Preferred Stock then in effect shall,
concurrently with the effectiveness of such reorganization or reclassification,
be proportionately adjusted so that the Preferred Stock shall be convertible
into, in lieu of the number of shares of Common Stock which the holders would
otherwise have been entitled to receive, a number of shares of such other class
or classes of stock equivalent to the number of shares of Common Stock that
would have been subject to receipt by the holders upon conversion of the
Preferred Stock immediately before that change.

                (g) ADDITIONAL SERIES C PREFERRED STOCK ADJUSTMENT.

                     (i) In the event the Corporation issues at any time or from
time to time an aggregate of more than two hundred fifty thousand (250,000)
shares of Additional Stock (as defined in Section B.5(g)(ii) hereof) during the
one (1) year period following the Original Issue Date for a consideration per
share less than the Series C Conversion Price in effect immediately prior to the
issuance of such Additional Stock, then the Series C Conversion Price in effect
immediately prior to such issuance shall forthwith be reduced to the price per
share at which such Additional Stock is issued and sold. The Conversion Price
adjustment referred to in this Section B.5(g) shall not be applicable to any
shares of Preferred Stock other than the Series C Preferred Stock, nor shall any
other shares of Preferred Stock receive any Conversion Price adjustment on
account of any Series C Conversion Price adjustment effected pursuant to this
Section B.5(g). Any consideration received by the Corporation shall be
calculated as follows:

                          (A) In the case of the issuance of Common Stock for
cash, the consideration shall be deemed to be the amount of cash paid therefor
before deducting any reasonable discounts, commissions or other expenses
allowed, paid or incurred by the Corporation for any underwriting or otherwise
in connection with the issuance and sale thereof.

                          (B) In the case of the issuance of the Common Stock
for a consideration in whole or in part other than cash, the consideration other
than cash shall be deemed to be the fair value thereof as determined by the
Board of Directors irrespective of any accounting treatment.

<PAGE>

                          (C) In the case of the issuance of options to purchase
or rights to subscribe for Common Stock, securities by their terms convertible
into or exchangeable for Common Stock or options to purchase or rights to
subscribe for such convertible or exchangeable securities (which are not
excluded from the definition of Additional Stock), the following provisions
shall apply:

                    (x) The aggregate maximum number of shares of Common Stock
deliverable upon exercise of such options to purchase or rights to subscribe for
Common Stock shall be deemed to have been issued at the time such options or
rights were issued and for a consideration equal to the consideration
(determined in the manner provided in Section B.5(g)(i)(A) and B.5(g)(i)(B)), if
any, received by the Corporation upon the issuance of such options or rights
plus the minimum purchase price provided in such options or rights for the
Common Stock covered thereby; and
                     
                    (y) The aggregate maximum number of shares of Common Stock
deliverable upon conversion of or in exchange for any such convertible or
exchangeable securities or upon the exercise of options to purchase or rights to
subscribe for such convertible or exchangeable securities and subsequent
conversion or exchange thereof shall be deemed to have been issued at the time
such securities were issued or such options or rights were issued and for a
consideration equal to the consideration, if any, received by the Corporation
for any such securities and related options or rights, plus the additional
consideration, if any, to be received by the Corporation upon the conversion or
exchange of such securities or the exercise of any related options or rights
(the consideration in each case to be determined in the manner provided in
Sections B.5(g)(i)(A) and B.5(g)(i)(B)).

Articles of Incorporation or through any reorganization, transfer of assets,
consolidation, merger, dissolution, issue or sale of securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms to be observed or performed hereunder by the Corporation, but will at
all times in good faith assist in the carrying out of all the provisions of this
Section B.5 and in the taking of all such action as may be necessary or
appropriate in order to protect the Conversion Rights of the holders of the
Preferred Stock against impairment.

                (i) CERTIFICATES OF ADJUSTMENT. Upon the occurrence of each
adjustment or readjustment of any Conversion Price pursuant to this Section B.5,
the Corporation at its expense shall promptly compute such adjustment or
readjustment in accordance with the terms hereof and prepare and furnish to each
holder of Preferred Stock a certificate executed by the Corporation's President
or Chief Financial Officer setting forth such adjustment or readjustment and
showing in detail the facts upon which such adjustment or readjustment is based.
The Corporation shall, upon the written request at any time of any holder of
Preferred Stock, furnish or cause to be furnished to such holder a like
certificate setting forth (i) such adjustments and readjustments, (ii) the
Conversion Price for such Preferred Stock at the time in effect, and (iii) the
number of shares of Common Stock and the amount, if any, of other property which
at the time would be received upon the conversion of such Preferred Stock.

               (j) NOTICES OF RECORD DATE. In the event that the Corporation
shall propose at any time: (i) to declare any dividend or distribution upon its
Common Stock, whether in cash, property, stock or other securities, whether or
not a regular cash dividend and whether or not out of earnings or earned
surplus; (ii) to offer for subscription pro rata to the holders of any class or
series of its stock any additional shares of stock of any class or series or
other rights; (iii) to effect any reclassification or recapitalization of its
Common Stock outstanding involving a change in the Common Stock; or (iv) to
effect any Corporate Reorganization, as defined in Section B.2(a) above, or to
sell, lease or convey all or substantially all of its assets, or to liquidate,
dissolve or wind up; then, in connection with each such event, the Corporation
shall send to the holders of Preferred Stock:

<PAGE>

                (1) at least twenty (20) days' prior written notice of the date
on which a record shall be taken for such dividend, distribution or subscription
rights (and specifying the date on which the holders of Common Stock shall be
entitled thereto) or for determining rights to vote, if any, in respect of the
matters referred to in (iii) and (iv) above; and

                (2) in the case of the matters referred to in (iii) and (iv)
above, at least twenty (20) days' prior written notice of the date when the same
shall take place (and specifying the date on which the holders of Common Stock
shall be entitled to exchange their Common Stock for securities or other
property deliverable upon the occurrence of such event).

                (k) ISSUE TAXES. The Corporation shall pay any and all issue and
other taxes that may be payable in respect of any issue or delivery of shares of
Common Stock on conversion of Preferred Stock pursuant hereto; provided,
however, that the Corporation shall not be obligated to pay any transfer taxes
resulting from any transfer requested by any holder in connection with any such
conversion.

                (l) RESERVATION OF STOCK ISSUABLE UPON CONVERSION. The
Corporation shall at all times reserve and keep available out of its authorized
but unissued shares of Common Stock, solely for the purpose of effecting the
conversion of the shares of the Preferred Stock, such number of its shares of
Common Stock as shall from time to time be sufficient to effect the conversion
of all outstanding shares of the Preferred Stock; and if at any time the number
of authorized but unissued shares of Common Stock shall not be sufficient to
effect the conversion of all then outstanding shares of the Preferred Stock, the
Corporation will take such corporate action as may, in the opinion of its
counsel, be necessary to increase its authorized but unissued shares of Common
Stock to such number of shares as shall be sufficient for such purpose,
including, without limitation, engaging in best efforts to obtain the requisite
shareholder approval of any necessary amendment to these Articles of
Incorporation.

                (m) FRACTIONAL SHARES. No fractional share shall be issued upon
the conversion of any share of Preferred Stock. All shares of Common Stock
(including fractions thereof) issuable upon conversion of more than one share of
a series of Preferred Stock by a holder thereof shall be aggregated for purposes
of determining whether the conversion would result in the issuance of any
fractional share. If, after the aforementioned aggregation, the conversion would
result in the issuance of a fraction of a share of Common Stock, the Corporation
shall, in lieu of issuing any fractional shares, pay the 

<PAGE>

holder otherwise entitled to such fraction a sum in cash equal to the fair 
market value of such fraction on the date of conversion (as determined in 
good faith by the Board of Directors).

                (n) NOTICES. Any notice required by the provisions of this
Section B.5 to be given to a holder of Preferred Stock shall be deemed given
when personally delivered to such holder or five (5) business days after the
same has been deposited in the United States mail, certified or registered mail,
return receipt requested, postage prepaid, and addressed to such holder at its
address appearing on the books of the Corporation.

          6. SERIES A RESTRICTIVE COVENANTS. So long as any shares of the Series

without first obtaining the approval (by vote or written consent, as provided by
law) of the holders of not less than a majority of the total number of shares of
Series A Preferred Stock then outstanding:

                (a) repurchase any Common Stock (except repurchases of Common

affects the powers, preferences or special rights of the Series B Preferred
Stock

C Preferred Stock shall be issued and outstanding, the Corporation shall not,

Series C Preferred Stock then outstanding:

               (a) repurchase any Common Stock (except repurchases of Common

upon written demand on the corporation, for a purpose reasonably related to such
holder's interest as a shareholder or holder of a voting trust certificate. Such
inspection and copying under this section may be made in person or by agent or
attorney.

   The accounting books and records and minutes of proceedings of the
shareholders and the Board and committees of the Board also shall be open to
inspection upon the written demand on the corporation of any shareholder or any
holder of a voting trust certificate at any reasonable time during usual
business hours, for a purpose reasonably related to such holder's interests as a
shareholder or holder of such voting trust certificate. Such inspection shall be
made in person or by agent or attorney, and the right of inspection includes the
right to copy and make extracts.

   Shareholders shall also have the right to inspect the original or copy of
these Bylaws, as amended to date, kept at the corporation's principal executive
office, at all reasonable times during business hours.

SECTION 2. INSPECTION BY DIRECTORS

   Every director shall have the absolute right at any reasonable time to
inspect and copy all books, records, and documents of every kind and to inspect
the physical properties of the corporation of which such person is director and
also of its subsidiary corporations, domestic and foreign. Such inspection shall
be made in person or by agent or attorney and the right to inspection includes
the right to copy and make extracts. Upon specific request, every director shall
have the absolute right to receive, at no cost and in a timely manner, copies of
any regular report or document produced within the company. Upon refusal of
demand for inspection by a director the superior court of the proper county may
enforce such inspection

<PAGE>

and order the payment of reasonable attorneys feces and other court costs to the
complaining director, agent or attorney.

   The performance of each officer is directly subject to the review of the
board of directors. As an extension of directors rights of inspection, any
director, their agent or attorney may initiate their own performance review at
any time by interviewing any officer, his/her peers, and his/her subordinates.
Such interviewing by directors shall not imply any executive authority by such
persons(s) not otherwise authorized, but is merely an information gathering
device in furtherance of corporate governance. The company will request that
such officers and employees speak candidly and openly to any questions presented
by any director, agent, or attorney pertaining to any actual or potential
company business. This paragraph shall not be deemed to increase directors
liability nor shall it be deemed to restrict or inhibit any rights directors
otherwise have.(2)

   If any record subject to inspection pursuant to this chapter is not
maintained in written form, a request for inspection is not complied with unless
and until the corporation, at its expense, makes such record available in
written form.

SECTION 4. WAIVER OF ANNUAL REPORT

   The annual report to shareholders, described in Section 1501 of the
California Corporations Code, is hereby expressly waived. Nothing in this
section shall prevent the corporation from issuing said report upon direction of
the Board.

SECTION 5. CONTRACTS, ETC.

The Board of Directors, except as otherwise provided in the Bylaws, may
authorize any officer or officers, agent or agents, to enter into any contract
or execute any instrument in the name and on the behalf of the corporation. Such
authority may be general or confined to specific instances. Unless so
authorized, no officer, agent or employee shall have any power or authority to
bind the corporation by any contract or engagement, or to pledge its credit, or
to render it liable for any purpose or to any amount.

provisions of Section 317 of the California Corporations Code. The corporation
shall advance the expenses reasonably expected to be incurred by such agent in
defending any such proceeding upon receipt of the undertaking required by

register.

SECTION 3. RECORD DATE AND CLOSING OF TRANSFER BOOKS

   The Board of Directors may fix a time in the future as record date for the
determination of the shareholders entitled to notice of and to vote at any
meeting of shareholders or entitled to receive payment of any dividend or
distribution, or any allotment of rights, or to exercise rights in respect to
any other lawful action. The record date so fixed shall be not more than sixty
(60) nor less than ten (10) days prior to the date of the meeting or event for
the purpose of which it is fixed. When a record date is so fixed, only the

exercise the rights as the case may be, notwithstanding any transfer of shares
on the books of the corporation after the record date.

statement filed by the Company covering an underwritten offering of any of its

<PAGE>

related to the issuance of such securities) exceed Five Million Dollars
($5,000,000) the Company will:

                (i) promptly give written notice of the proposed registration to
all other Holders; and

               (ii) as soon as practicable, use its best efforts to effect 
such registration (including, without limitation, filing post-effective 
amendments, appropriate qualifications under applicable blue sky or other 
state securities laws, and appropriate compliance with the Securities Act) as

received by the Company within twenty (20) days after such written notice

                     The Company shall not be obligated to effect, or to take
any action to effect, any such registration pursuant to this Section 1.2:

                     (A) In any particular jurisdiction in which the Company
would be required to execute a general consent to service of process in
effecting such registration, qualification, or compliance, unless the Company is
already subject to service in such jurisdiction and except as may be required by
the Securities Act and applicable Blue Sky laws;

                     (B) As to a request by the Initiating Series A Holders,
after the Company has initiated one such registration pursuant to this Section
1.2(a) at the request of the Initiating Series A Holders, and, as to a request
by the Initiating Series B Holders, after the Company has initiated one such
registration pursuant to this Section 1.2(a) at the request of the Initiating
Series B Holders and, as to a request by the Initiating Series C Holders, after
the Company has initiated one such registration pursuant to this Section 1.2(a)
at the request of the Initiating Series C Holders (counting for these purposes
only (x) a registration which has been declared or ordered effective and
pursuant to which securities have been sold and (y) registrations which have
been withdrawn by the Holders as to which the Holders have not elected to bear
the Registration Expenses pursuant to Section 1.4 hereof and would, absent such
election, have been required to bear such expenses);

                     (C) During the period starting with the date sixty (60)
days prior to the Company's good faith estimate of the

<PAGE>

date of filing of, and ending on a date one hundred eighty (180) days after the
effective date of, a Company-initiated registration; provided that the Company
is actively employing in good faith all reasonable efforts to cause such
registration statement to become effective;

                     (D) If the Initiating Holders propose to dispose of shares
of Registrable Securities which may be immediately registered on Form S-3
pursuant to a request made under Section 1.5 hereof;

                     (E) If the Initiating Holders do not request that such
offering be firmly underwritten by underwriters selected by the Initiating
Holders (subject to the consent of the Company, which consent will not be
unreasonably withheld); or

                     (F) If the Company and the Initiating Holders are unable to
obtain the commitment of the underwriter described in clause (E) above to firmly
underwrite the offer.

           (b) FILING. Subject to the foregoing clauses (A) through (F), the
Company shall file a registration statement covering the Registrable Securities
so requested to be registered as soon as practicable after receipt of the
request or requests of the Initiating Holders; provided, however, that if (i) in
the good faith judgment of the Board of Directors of the Company, such
registration would be seriously detrimental to the Company and the Board of
Directors of the Company concludes, as a result, that it is essential to defer
the filing of such registration statement at such time, and (ii) the Company
shall furnish to such Holders a certificate signed by the President of the
Company stating that in the good faith judgment of the Board of Directors of the
Company, it would be seriously detrimental to the Company for such registration
statement to be filed in the near future and that it is, therefore, essential to
defer the filing of such registration statement, then the Company shall have the
right to defer such filing for the period during which such disclosure would be
seriously detrimental, provided that (except as provided in clause (C) above)
the Company may not defer the filing for a period of more than one hundred
eighty (180) days after receipt of the request of the Initiating Holders, and,
provided further, that the Company shall not defer its obligation in this manner
more than once in any twelve-month period.

                The registration statement filed pursuant to the request of the
Initiating Holders may, subject to the provisions of Sections 1.2(d) and 1.13
hereof, include other securities of the Company, with respect to which
registration rights have been

<PAGE>

granted, and may include securities of the Company being sold for the account of
the Company.

           (c) UNDERWRITING. The right of any Holder to registration pursuant to
Section 1.2 shall be conditioned upon such Holder's participation in such
underwriting and the inclusion of such Holder's Registrable Securities in the
underwriting (unless otherwise mutually agreed by a majority in interest of the
Initiating Holders and such Holder with respect to such participation and
inclusion) to the extent provided herein. A Holder may elect to include in such
underwriting all or a part of the Registrable Securities he holds.

           (d) PROCEDURES. If the Company shall request inclusion in any
registration pursuant to Section 1.2 of securities being sold for its own
account, or if other persons shall request inclusion in any registration
pursuant to Section 1.2, the Initiating Holders shall, on behalf of all Holders,
offer to include such securities in the underwriting and may condition such
offer on their acceptance of the further applicable provisions of this Section 1
(including Section 1.12). The Company shall (together with all Holders and other
persons proposing to distribute their securities through such underwriting)
enter into an underwriting agreement in customary form with the representative
of the underwriter or underwriters selected for such underwriting by a majority
in interest of the Initiating Holders, which underwriters are reasonably
acceptable to the Company. Notwithstanding any other provision of this Section
1.2, if the representative of the underwriters advises the Initiating Holders in
writing that marketing factors require a limitation on the number of shares to
be underwritten, the number of shares to be included in the underwriting or
registration shall be allocated as set forth in Section 1.13 hereof. If a person
who has requested inclusion in such registration as provided above does not
agree to the terms of any such underwriting, such person shall be excluded
therefrom by written notice from the Company, the underwriter or the Initiating
Holders. The securities so excluded shall also be withdrawn from registration.
Any Registrable Securities or other securities excluded shall also be withdrawn
from such registration. If shares are so withdrawn from the registration and if
the number of shares to be included in such registration was previously reduced
as a result of marketing factors pursuant to this Section 1.2(d), then the
Company shall offer to all holders who have retained rights to include
securities in the registration the right to include additional securities in the
registration in an aggregate amount equal to the number of shares so withdrawn,
with such shares to be allocated among such Holders requesting additional
inclusion in accordance with the provisions of Section 1.13.

     1.3 COMPANY REGISTRATION.

           (a) If the Company shall determine to register any of its securities
either for its own account or the account of a security holder or holders
exercising their respective demand registration rights (other than pursuant to
Section 1.2 or 1.5 hereof), other than a registration relating solely to
employee benefit plans, or a registration relating solely to a Rule 145
transaction, or a registration on any registration form that does not permit
secondary sales, the Company will:

            (i) promptly give to each Holder written notice
thereof: and

           (ii) use its best efforts to include in such registration (and any
related qualification under blue sky laws or other compliance), except as set
forth in Section 1.3(b) below, and in any underwriting involved therein, all the
Registrable Securities specified in a written recluse or requests made by any
Holder within twenty (20) days after the written notice from the Company
described in clause (i) above is given. Such written request may specify the
inclusion of all or a part of a Holder's Registrable Securities in such
registration.

           (b) UNDERWRITING. If the registration of which the Company gives
notice is for a registered public offering involving an underwriting, the
Company shall so advise the Holders as a part of the written notice given
pursuant to Section 1.3(a)(i). In such event, the right of any Holder to
registration pursuant to this Section 1.3 shall be conditioned upon such
Holder's participation in such underwriting and the inclusion of such Holder's
Registrable Securities in the underwriting to the extent provided herein. All
Holders proposing to distribute their securities through such underwriting shall
(together with the Company and the other holders of securities of the Company
with registration rights to participate therein distributing their securities
through such underwriting) enter into an underwriting agreement in customary
form with the representative of the underwriter or underwriters selected by the
Company.

           Notwithstanding any other provision of this Section 1.3, if the
representative of the underwriters advises the Company in writing that marketing
factors require a limitation on the number of shares to be underwritten, the
representative may (subject to the limitations set forth below) exclude all
Registrable Securities from, or limit the number of Registrable Securities to be
included in, the registration and underwriting. If the registration is the first
Company-initiated registered offering of the Company's

<PAGE>

securities to the general public, the Company may limit, to the extent so
advised by the underwriters, the amount of securities (including Registrable
Securities) to be included in the registration by the Company's shareholders
(including the Holders), or may exclude, to the extent so advised by the
underwriters, such underwritten securities entirely from such registration. If
such registration is the second or any subsequent Company-initiated registered
offering of the Company's securities to the general public, the Company may
limit, to the extent so advised by the underwriters, the amount of securities to
be included in the registration by the Company's shareholders (including the
Holders); provided, however, that the aggregate value of securities (including
Registrable Securities) to be included in such registration by the Company's
shareholders (including the Holders) may not be so reduced to less than twenty-
five percent (25%) of the total value of all securities included in such
registration; PROVIDED FURTHER, however, that the aforementioned 25% shall be
reduced, pro rata, to accommodate the comparable rights of Other Shares as
referenced in Section 1.13 of this Agreement.

                The Company shall so advise all holders of securities requesting
registration, and the number of securities that are entitled to be included in
the registration and underwriting shall be allocated first to the Company for
securities being sold for its own account and thereafter as set forth in Section
1.13. If any person does not agree to the terms of any such underwriting, he
shall be excluded therefrom by written notice from the Company or the
underwriter. Any Registrable Securities or other securities excluded or
withdrawn from such underwriting shall be withdrawn from such registration.

                If shares are so withdrawn from the registration or if the
number of shares of Registrable Securities to be included in such registration
was previously reduced as a result of marketing factors, the Company shall then
offer to all persons who have retained the right to include securities in the
registration the right to include additional securities in the registration in
an aggregate amount equal to the number of shares so withdrawn, with such shares
to be allocated among the persons requesting additional inclusion in accordance
with Section 1.13 hereof.

     1.4 EXPENSES OF REGISTRATION. All Registration Expenses incurred in
connection with any registration, qualification or compliance pursuant to
Sections 1.2, 1.3, and 1.5 hereof, and reasonable fees of one counsel for the
selling shareholders in the case of registrations pursuant to Section 1.2 or
Section 1.3, shall be borne by the Company except as otherwise required by law;
provided, however, that if the Holders bear the Registration Expenses

<PAGE>

for any registration proceeding begun pursuant to Section 1.2 and subsequently
withdrawn by the Holders registering shares therein, such registration
proceeding shall not be counted as a requested registration pursuant to Section
1.2 hereof, except in the event that such withdrawal is based upon material
adverse information relating to the Company that is different from the
information known or available (upon request from the Company or otherwise) to
the Holders requesting registration at the time of their request for
registration under Section 1.2, in which event such registration shall not be
treated as a counted registration for purposes of Section 1.2 hereof, even
though the Holders do not bear the Registration Expenses for such registration.
Except as provided in the first sentence of this Section 1.4, all Selling
Expenses relating to securities so registered shall be borne by the holders of
such securities pro rata on the basis of the number of shares of securities so
registered on their behalf.

     1.5 REGISTRATION ON FORM S-3.

           (a) After its initial public offering, the Company shall use its best
efforts to qualify for registration on Form S-3 or any comparable or successor
form or forms. After the Company has qualified for the use of Form S-3, in
addition to the rights contained in the foregoing provisions of this Section 1,
the Holders of Registrable Securities shall have the right to request
registrations on Form S-3 (such requests shall be in writing and shall state the
number of shares of Registrable Securities to be disposed of and the intended
methods of disposition of such shares by such Holder or Holders); provided,
however, that the Company shall not be obligated to effect any such registration
if (i) the Holders, together with the holders of any other securities of the
Company entitled to inclusion in such registration, propose to sell Registrable
Securities and such other securities (if any) on Form S-3 at an aggregate price
to the public of less than One Million Dollars ($1,000,000), or (ii) in the
event that the Company shall furnish the certification described in Section
1.2(b) (but subject to the limitations set forth therein) or (iii) in a given
twelve (12)-month period, after the Company has effected two (2) such
registrations in any such period or (iv) it is to be effected more than five (5)
years after the Company's initial public offering.

           (b) If a request complying with the requirements of Section 1.5(a)
hereof is delivered to the Company, the provisions of Sections 1.2(a)(i) and
(ii) and Section 1.2(b) hereof shall apply to such registration. If the
registration is for an underwritten offering, the provisions of Sections 1.2(c)
and 1.2(d) hereof shall apply to such registration.

<PAGE>

     1.6 REGISTRATION PROCEDURES. In the case of each registration effected by
the Company pursuant to Section 1, the Company will keep each Holder advised in
writing as to the initiation of each registration and as to the completion
thereof. At its expense, the Company will use its best efforts to:

           (a) Keep such registration effective for a period of one hundred
twenty (120) days or until the Holder or Holders have completed the distribution
described in the registration statement relating thereto, whichever first
occurs; provided, however, that (i) such 120-day period shall be extended for a
period of time equal to the period the Holder refrains from selling any
securities included in such registration at the request of an underwriter of
Common Stock (or other securities) of the Company; and (ii) in the case of any
registration of Registrable Securities on Form S-3 which are intended to be
offered on a continuous or delayed basis, such 320-day period shall be extended,
if necessary, to keep the registration statement effective until all such
Registrable Securities are sold. provided that Rule 145, or any successor rule
under the Securities Act, permits an offering on a continuous or delayed basis,
and provided further that applicable rules under the Securities Act governing
the obligation to file a post-effective amendment permit, in lieu of filing a
post-effective amendment that (I) includes any prospectus required by Section
10(a)(3) of the Securities Act or (II) reflects facts or events representing a
material or fundamental change in the information set forth in the registration
statement, the incorporation by reference of information required to be included
in (I) and (II) above to be contained in periodic reports filed pursuant to
Section 13 or l5 (d) of the Exchange Act in the registration statement:

           (b) Prepare and file with the Commission such amendments and
supplements to such registration statement and the prospectus used in connection
with such registration statement as may be necessary to comply with the
provisions of the Securities Act with respect to the disposition of all
securities covered by such registration statement;

           (c) Furnish such number of prospectuses and other documents incident
thereto, including any amendment of or supplement to the prospectus, as a Holder
from time to time may reasonably request;

           (d) Notify each seller of Registrable Securities covered by such
registration statement at any time when a prospectus relating thereto is
required to be delivered under the Securities Act of the happening of any event
as a result of which the prospectus included in such registration statement, as
then in

<PAGE>

effect, includes an untrue statement of a material fact or omits to state a
material fact required to be stated therein or necessary to make the statements
therein not misleading or is incomplete in the light of the circumstances then
existing, and at the request of any such seller, prepare and furnish to such
seller a reasonable number of copies of a supplement to or an amendment of such
prospectus as may be necessary so that, as thereafter delivered to the
purchasers of such shares, such prospectus shall not include an untrue statement
of a material fact or omit to state a material fact required to be stated
therein or necessary to make the statements therein not misleading or incomplete
in the light of the circumstances then existing;

           (e) Cause all such Registrable Securities registered pursuant
hereunder to be listed on each securities exchange on which similar securities
issued by the Company are then listed;

           (f) Provide a transfer agent and registrar for all Registrable
Securities registered pursuant to such registration statement and a CUSIP number
for all such Registrable Securities, in each case not later than the effective
date of such registration;

           (g) Otherwise use its best efforts to comply with all applicable
rules and regulations of the Commission, and make available to its security
holders, as soon as reasonably practicable, an earnings statement covering the
period of at least twelve months, but not more than eighteen months, beginning
with the first month after the effective date of the Registration Statement,
which earnings statement shall satisfy the provisions of Section ll(a) of the
Securities Act: and

           (h) In connection with any underwritten offering pursuant to a
registration statement filed pursuant to Section 1.2 hereof, the Company will
enter into an underwriting agreement reasonably necessary to effect the offer
and sale of Common Stock, provided such underwriting agreement contains
customary underwriting provisions and provided further that if the underwriter
so requests the underwriting agreement will contain customary contribution
provisions.

1.7 INDEMNIFICATION.

           (a) The Company will indemnify each Holder, each of its officers,
directors and partners, legal counsel and accountants and each person
controlling such Holder within the meaning of Section 15 of the Securities Act,
with respect to which registration, qualification, or compliance has been
effected pursuant to this Section 1, and each underwriter, if any, and each
person who

<PAGE>

controls within the meaning of Section 15 of the Securities Act any underwriter,
against all expenses, claims, losses, damages, and liabilities (or actions,
proceedings, or settlements in respect thereof) arising out of or based on any
untrue statement (or alleged untrue statement) of a material fact contained in
any prospectus, offering circular, or other document (including any related
registration statement, notification, or the like) incident to any such
registration, qualification, or compliance, or based on any omission (or alleged
omission) to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, or any violation by the
Company of the Securities Act or any rule or regulation thereunder applicable to
the Company and relating to action or inaction required of the Company in
connection with any such registration, qualification, or compliance, and will
reimburse each such Holder, each of its officers, directors, partners, legal
counsel, and accountants and each person controlling such Holder, each such
underwriter, and each person who controls any such underwriter, for any legal
and any other expenses reasonably incurred in connection with investigating and
defending or settling any such claim, loss, damage, liability, or action,
provided that the Company will not be liable in any such case to the extent that
any such claim, loss, damage, liability or expense arises out of or is based on
any untrue statement or omission based upon written information furnished to the
Company by such Holder or underwriter and stated

<PAGE>

to be specifically for use therein. It is agreed that the indemnity agreement
contained in this Section 1.7(a) shall not apply to amounts paid in settlement
of any such loss, claim, damage, liability, or action if such settlement is
effected without the consent of the Company (which consent has not been
unreasonably withheld).

           (b) Each Holder will, if Registrable Securities held by him are
included in the securities as to which such registration, qualification, or
compliance is being effected, indemnify the Company, each of its directors,
officers, partners, legal counsel, and accountants and each underwriter, if any,
of the Company's securities covered by such a registration statement, each
person who controls the Company or such underwriter within the meaning of
Section 15 of the Securities Act, each other such Holder and Other shareholders
participating in such registration, and each of their officers, directors, and
partners, and each person controlling such Holder or Other Shareholder, against
all expenses, claims, losses, damages and liabilities (or actions in respect
thereof) arising out of or based on any untrue statement (or alleged untrue
statement) of a material fact contained in any such registration statement,
prospectus, offering circular, or other document, or any omission (or alleged
omission) to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, and will reimburse the
Company and such Holders, Other Shareholders, directors, officers, partners,
legal counsel, and accountants, persons, underwriters, or control persons for
any legal or any other expenses reasonably incurred in connection with
investigating or defending or settling any such claim, loss, damage, liability,
or action, in each case to the extent, but only to the extent, that such untrue
statement (or alleged untrue statement) or omission (or alleged omission) is
made in such registration statement, prospectus, offering circular, or other
document in reliance upon and in conformity with written information furnished
to the Company by such Holder; provided, however, that the obligations of such
Holder hereunder shall not apply to amounts paid in settlement of any such
claims, losses, damages, or liabilities (or actions in respect thereof) if such
settlement is effected without the consent of such Holder (which consent shall
not be unreasonably withheld). Notwithstanding the foregoing, the liability of
each Holder under this Section 1.7 shall be limited to an amount equal to the
aggregate public offering price of the Registrable Securities sold by such
Holder, unless such liability arises out of or is based upon willful misconduct
by such Holder.

           (c) Each party entitled to indemnification under this Section 1.7
(the "Indemnified Party") shall give notice to the party required to provide
indemnification (the "Indemnifying

<PAGE>

Party") promptly after such Indemnified Party has actual knowledge of any claim
as to which indemnity may be sought, and shall permit the Indemnifying Party to
assume the defense of any such claim or any litigation resulting therefrom,
provided that counsel for the Indemnifying Party, who shall conduct the defense
of such claim or any litigation resulting therefrom, shall be approved by the
Indemnified Party (whose approval shall not unreasonably be withheld), and the
Indemnified Party may participate in such defense at such party's expense, and
provided further that the failure of any Indemnified Party to give notice as
provided herein shall not relieve the Indemnifying Party of its obligations
under this Section 1, to the extent such failure is not prejudicial. No
Indemnifying Party, in the defense of any such claim or litigation, shall,
except with the consent of each Indemnified Party, consent to entry of any
judgment or enter into any settlement that does not include as an unconditional
term thereof the giving by the claimant or plaintiff to such Indemnified Party
of a release from all liability in respect to such claim or litigation. Each
Indemnified Party shall furnish such information regarding itself or the claim
in question as an Indemnifying Party may reasonably request in writing and as
shall be reasonably required in connection with defense of such claim and
litigation resulting therefrom.

           (d) If the indemnification provided for in this Section 1.7 is held
by a court of competent jurisdiction to be unavailable to an Indemnified Party
with respect to any loss, liability, claim, damage, or expense referred to
therein, then the Indemnifying Party, in lieu of indemnifying such Indemnified
Party hereunder, shall contribute to the amount paid or payable by such
Indemnified Party as a result of such loss, liability, claim, damage, or expense
in such proportion as is appropriate to reflect the relative fault of the
Indemnifying Party on the one hand and of the Indemnified Party on the other in
connection with the statements or omissions that resulted in such loss,
liability, claim, damage, or expense as well as any other relevant equitable
considerations. The relative fault of the Indemnifying Party and of the
Indemnified Party shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the
omission to state a material fact relates to information supplied by the
Indemnifying Party or by the Indemnified Party and the parties' relative intent,
knowledge, access to information, and opportunity to correct or prevent such
statement or omission.

           (e) Notwithstanding the foregoing, to the extent that the provisions
on indemnification and contribution contained in the underwriting agreement
entered into in connection with the underwritten public offering are in conflict
with the foregoing provisions, the provisions in the underwriting agreement
shall control.

<PAGE>

     1.8 INFORMATION BY HOLDER. Each Holder of Registrable Securities shall 
furnish to the Company such information regarding such Holder and the 
distribution proposed by such Holder as the Company may reasonably request in 
writing and as shall be reasonably required in connection with any 
registration, qualification, or compliance referred to in this Section 1.

     1.9 LIMITATIONS ON REGISTRATION OF ISSUES OF SECURITIES. From and after the
date of this Agreement, the Company shall not, without the prior written consent
of a majority in interest of the Holders, enter into any agreement with any
holder or prospective holder of any securities of the Company giving such holder
or prospective holder any registration rights the terms of which are more
favorable than the registration rights granted to the Holders hereunder.

     1.10 RULE 144 REPORTING. With a view to making available the benefits of
certain rules and regulations of the Commission that may permit the sale of the
Registrable Securities to the public without registration, the Company agrees to
use its best efforts to

           (a) Make and keep public information regarding the Company available
as those terms are understood and defined in Rule 144 under the Securities Act,
at all times from and after ninety (90) days following the effective date of the
first registration under the Securities Act filed by the Company for an offering
of its securities to the general public;

           (b) File with the Commission in a timely manner all reports and other
documents required of the Company under the Securities Act and the Exchange Act
at any time after it has become subject to such reporting requirements;

           (c) So long as a Holder owns any Registrable Securities, furnish to
the Holder forthwith upon written request a written statement by the Company as
to its compliance with the reporting requirements of Rule 144 (at any time from
and after ninety (90) days following the effective date of the first
registration statement filed by the Company for an offering of its securities to
the general public), and of the Securities Act and the Exchange Act (at any time
after it has become subject to such reporting requirements), a copy of the most
recent annual or quarterly report of the Company, and such other reports and
documents so filed as a Holder may reasonably request in availing itself of any
rule or regulation of the Commission allowing a holder to sell any such
securities without registration.

<PAGE>

     1.11 TRANSFER OR ASSIGNMENT OF REGISTRATION RIGHTS. The rights to cause the
Company to register securities granted to a Holder by the Company under this
Section 1 may be transferred or assigned by a Holder only to (i) a transferee or
assignee of not less than fifty thousand (50,000) shares of Registrable
Securities (as presently constituted and subject to subsequent adjustments for
stock splits, stock dividends, reverse stock splits, and the like) or (ii) an
affiliate of a Holder, provided that the Company is given written notice at the
time of or within a reasonable time after said transfer or assignment, stating
the name and address of the transferee or assignee and identifying the
securities with respect to which such registration rights are being transferred
or assigned, and, provided further, that the transferee or assignee of such
rights assumes the obligations of such Holder under this Section 1.

     1.12 "MARKET STAND-OFF" AGREEMENT. If requested by the Company and an
underwriter of Common Stock (or other securities) of the Company, each
Shareholder and Founder shall not sell or otherwise transfer or dispose of any
Common Stock (or other securities) of the Company held by such Shareholder
(other than those included in the registration) during the one hundred eighty
(180) day period following the effective date of a registration statement of the
Company filed under the Securities Act, provided that:

           (a) such agreement shall only apply to the first such registration
statement of the Company, including securities to be sold on its behalf to the
public in an underwritten offering; and

           (b) all Holders and officers and directors of the Company enter into
similar agreements.

                The obligations described in this Section 1.12 shall not apply
to a registration relating solely to employee benefit plans on Form S-1 or Form
S-8 or similar forms that may be promulgated in the future, or a registration
relating solely to a Commission Rule 145 transaction on Form S-4 or similar
forms that may be promulgated in the future. The Company may impose stoptransfer
instructions with respect to the shares (or securities) subject to the foregoing
restriction until the end of said one hundred eighty (180) day period.

      1.13 ALLOCATION OF REGISTRATION OPPORTUNITIES. In any circumstance in
which all of the Registrable Securities and other shares of Common Stock of the
Company (including shares of Common Stock issued or issuable upon conversion of
shares of any currently unissued series of Preferred Stock of the Company) with
registration rights (the "Other Shares") requested to be included in a
registration on behalf of the Holders or other selling shareholders

<PAGE>

cannot be so included as a result of limitations on the aggregate number of
shares of Registrable Securities and Other Shares that may be so included, the
number of shares of Registrable Securities and Other Shares that may be so
included shall be allocated among the Holders and other selling shareholders
requesting inclusion of shares pro rata on the basis of the number of shares of
Registrable Securities and Other Shares that would be held by such Holders and
other selling shareholders, assuming conversion into Common Stock; provided,
however, that such allocation shall not operate to reduce the aggregate number
of Registrable Securities and Other Shares to be included in such registration.
If any Holder or other selling shareholder does not request inclusion of the
maximum number of shares of Registrable Securities and Other Shares allocated to
him pursuant to the above-described procedure, the remaining portion of his
allocation shall be reallocated among those requesting Holders and other selling
shareholders whose allocations did not satisfy their requests pro rata on the
basis of the number of shares of Registrable Securities and Other Shares which
would be held by such Holders and other selling shareholders, assuming
conversion into Common Stock, and this procedure shall be repeated until all the
shares of Registrable Securities and Other Shares which may be included in the
registration on behalf of the Holders and other selling shareholders have been
so allocated. The Company shall not limit the number of Registrable Securities
to be included in a registration pursuant to this Agreement in order to include
shares held by shareholders with no registration rights or to include founder's
stock or any other shares of stock issued to employees, officers, directors, or
consultants, or with respect to registrations under Section 1.2 or 1.5 hereof,
in order to include in such registration securities registered for the Company's
own account.

     1.14 DELAY OF REGISTRATION. No Holder shall have any right to take any
action to restrain, enjoin, or otherwise delay any registration as the result of
any controversy that might arise with respect to the interpretation or
implementation of this Section 1.

     1.15 TERMINATION OF REGISTRATION RIGHTS. The right of any Holder to request
registration or inclusion in any registration pursuant to Section 1.2, 1.3 or
1.5 shall terminate on the closing of the first Company-initiated registered
public offering of Common Stock of the Company, provided that all shares of
Registrable Securities held or entitled to be held upon conversion by such
Holder may immediately be sold under Rule 144 during any 90-day period, or on
such date after the closing of the first Companyinitiated registered public
offering of Common Stock of the Company as all shares of Registrable Securities
held or entitled to be held upon conversion by such Holder may immediately be
sold under Rule 144 during any 90-day period; provided, however, that the
provisions

<PAGE>

of this Section 1.15 shall not apply to any Holder who owns more than two
percent (2%) of the Company's outstanding stock until the earlier of (x) such
time as such Holder owns less than two percent (2%) of the outstanding stock of
the Company, or (y) the expiration of five (5) years after the closing of the
first registered public offering of Common Stock of the Company.

                                    SECTION 2
                            COVENANTS OF THE COMPANY

     The Company hereby covenants and agrees, so long as any Holder owns any
Registrable Securities, as follows:

     2.1 BASIC FINANCIAL INFORMATION. The Company will furnish the following
reports to any Holder, so long as such Holder (or its representative) owns at
least 191,000 Shares, or such number of shares of Common Stock issued upon

constituted and subject to subsequent adjustment for stock splits, stock
dividends, reverse stock splits, recapitalizations and the like (a "Significant

accountants of recognized national standing selected by the Company, and a
Company-prepared comparison to the Company's operating plan for such year.

           (b) As soon as practicable after the end of the first, second, and
third quarterly accounting periods in each fiscal year of the Company, and in
any event within forty-five (45) days thereafter, a consolidated balance sheet

quarterly period, and consolidated statements of income and sources and

accepting accounting principles consistently applied and setting forth in
comparative form the figures for the corresponding periods of the previous

all in reasonable detail and certified by the principal financial or accounting

           (c) From the date the Company becomes subject to the reporting

respectively.

     2.2 ADDITIONAL INFORMATION AND RIGHTS.

           (a) The Company will permit any Significant Holder (or a

make copies thereof and take extracts therefrom), and to discuss its affairs,
finances and accounts with the Company's officers and its independent public
accountants, all at such reasonable times and as often as any such person may
reasonably request.

           (b) The Company will deliver the reports described below in this
Section 2.2 to each Significant Holder:

the Company, which financial plan shall include a projection of income and a
projected cash flow statement for such fiscal year and a projected balance sheet

inspect their properties or discuss their affairs, finances and accounts, under
the laws of the jurisdictions in which they are incorporated.

           (d) Anything in Section 2 to the contrary notwithstanding, no Holder
or Significant Holder by reason of this Agreement shall have access to any trade
secrets or classified information of the Company. Each Significant Holder hereby
agrees to hold in confidence and trust and not to misuse or disclose any

Partners II, L.P. ("Matrix"), The Palmer Organization III, L.P. ("Palmer") 
and Archive and their respective successors and assignees holding at least 
one hundred thousand (100,000) shares of Common Stock of the Company 
(assuming conversion into Common Stock of Shares held by it) (Matrix, Palmer 
Archive and such successors and assignees are referred to collectively herein 
as the "Matrix/Palmer/Archive Holders") the right of first refusal to 
purchase a pro rata share of New Securities (as defined in this Section 2.3) 
which the Company ,may, from time to time, propose to sell and issue. A 
Matrix/Palmer/Archive Holder's pro rata share, for purposes of this right of 
first refusal, is the ratio of the number of shares of Common Stock owned by 
such Matrix/Palmer/Archive Holder immediately prior to the issuance of New 
Securities, assuming conversion into Common Stock of the Shares, to the total 
number of shares of Common Stock outstanding immediately prior to the 
issuance of New Securities, assuming full conversion of the Shares and 
exercise of all outstanding rights, options and warrants to acquire Common 
Stock of the Company. Each Matrix/Palmer/Archive Holder shall have a right of 
over-allotment such that if any Matrix/Palmer/Archive Holder fails to 
exercise its right hereunder to purchase its pro rata shares of New 
Securities, the other Matrix/Palmer/Archive Holders may purchase the 
nonpurchasing Matrix/Palmer/Archive Holder's portion on a pro rata basis 
within

<PAGE>

ten (10) days from the date such Matrix/Palmer/Archive Holders are notified by
the Company that such nonpurchasing Matrix/Palmer/Archive Holder has failed to
exercise its right hereunder to purchase its pro rata share of New Securities.
This right of first refusal shall be subject to the following provisions:

           (a) "New Securities" shall mean any capital stock (including Common
Stock and/or Preferred Stock) of the Company whether now authorized or not, and
rights, options or warrants to purchase such capital stock, and securities of
any type whatsoever that are, or may become, convertible into capital stock;
provided that the term "New Securities" does not include (i) securities
purchased under the Series C Agreement: (ii) securities issued upon conversion
of the Shares; (iii) securities issued pursuant to the acquisition of another
business entity or business segment of any such entity by the Company by merger,
purchase of substantially all the assets or other reorganization whereby the
Company will own not less than fifty-one percent (51%) of the voting power of
such business entity or business segment of any such entity; (iv) any
borrowings, direct or indirect, from financial institutions or other persons by
the Company, whether or not presently authorized, including any type of loan or
payment evidenced by any type of debt instrument, provided such borrowings do
not have any equity features including warrants, options or other rights to
purchase capital stock and are not convertible into capital stock of the
Company; (v) securities issued to employees, consultants, officers or directors
of the Company pursuant to any stock option, stock purchase or stock bonus plan,
agreement or arrangement approved by the Board of Directors; (vi) securities
issued to vendors or customers or to other persons in similar commercial
situations with the Company if such issuance is approved by the Board of
Directors; (vii) securities issued in connection with obtaining lease financing,
whether issued to a lessor, guarantor or other person; (viii) securities issued
in a firm commitment underwritten public offering pursuant to a registration
under the Securities Act other than a registration relating solely to a
transaction under Rule 145 under such Act (or any successor thereto) or to an
employee benefit plan of the Company, at a public offering price (prior to
underwriting discounts and expenses) equal to or exceeding Five Dollars and
Twenty Five Cents ($5.25) per share of Common Stock (as adjusted for any stock
dividends, combinations or splits with respect to such shares) and the aggregate
proceeds to the Company and/or any selling shareholders (after deduction for
underwriting discounts but excluding expenses relating to the issuance) of which
exceed Five Million Dollars ($5,000,000) (a "Qualified Public Offering"); (ix)
securities issued in connection with any stock split, stock dividend or
recapitalization of the Company; and (x) any right, option or warrant to acquire
any security convertible into the securities

<PAGE>

excluded from the definition of New Securities pursuant to subsections (i)
through (ix) above.

               (b) In the event the Company proposes to undertake an issuance of
New Securities, it shall give each Matrix/Palmer/ Archive Holder written notice
of its intention, describing the type of New Securities, and their price and the
general terms upon which the Company proposes to issue the same. Each
Matrix/Palmer/Archive Holder shall have twenty (20) days after any such notice
is effective to agree to purchase such Matrix/Palmer/Archive Holder's pro rata
share of such New Securities for the price and upon the terms specified in the
notice by giving written notice to the Company and stating therein the quantity
of New Securities to be purchased.

           (c) In the event a Matrix/Palmer/Archive Holder fails to exercise
fully the right of first refusal within said twenty (20) day period and after
the expiration of the ten-day period for the exercise of the over-allotment
provisions of this Section 2.3, the Company shall have one hundred twenty (120)
days thereafter to sell or enter into an agreement (pursuant to which the sale
of New Securities covered thereby shall be closed, if at all, within one hundred
twenty (120) days from the date of said agreement) to sell the New Securities
respecting which said Matrix/Palmer/Archive Holder's right of first refusal
option set forth in this Section 2.3 was not exercised, at a price and upon
terms no more favorable to the purchasers thereof than specified in the
Company's notice to the Matrix/Palmer/Archive Holders pursuant to Section
2.3(b). In the event the Company has not sold within said 120-day period or
entered into an agreement to sell the New Securities in accordance with the
foregoing within one hundred twenty (120) days from the date of said agreement),
the Company shall not thereafter issue or sell any New Securities, without first
again offering such securities to the Matrix/Palmer/Archive Holders in the
manner provided in Section 2.3(b) above.

           (d) The right of first refusal granted under this Agreement shall
expire upon, and shall not be applicable to, the first sale of Common Stock of
the Company to the public effected pursuant to a Qualified Public Offering, as
defined in Section 2.3(a)(viii) above.

     2.4 TRANSACTIONS WITH AFFILIATES. The Company shall not, without the
approval of the disinterested members of the Company's Board of Directors,
engage in any loans, leases, contracts or other transactions with any director,
officer or key employee of the Company, or any member of any such person's
immediate family, including the parents, spouse, children and other relatives of
any such person, on terms less favorable than the Company would obtain

<PAGE>

in a transaction with an unrelated party, as determined in good faith by the
Board of Directors.

          2.5 TERMINATION OF COVENANTS. The covenants set forth in this Section
2 shall terminate and be of no further force and effect after the time of
effectiveness of the Company's first Qualified Public offering, as defined in
Section 2.3(a)(viii) above.

THIS WARRANT AND THE SHARES ISSUABLE HEREUNDER HAVE NOT BEEN REGISTERED UNDER
THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD, PLEDGED, OR
OTHERWlSE TRANSFERRED WITHOUT AN EFFECTIVE REGISTRATION THEREOF UNDER SUCH ACT
OR PURSUANT TO RULE 144 OR AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE
CORPORATION AND ITS COUNSEL THAT SUCH REGISTRATION IS NOT REQUIRED.

                              WARRANT TO PURCHASE STOCK

Company: Overland Data, Inc., a California corporation
Number of Shares: 17,046
Class of Stock: Common
Initial Exercise Price: $4.40 per share
Issue Date: May 15, 1995
Expiration Date: May 15, 2000 (subject to Article 4.1)

    THIS WARRANT CERTIFIES THAT, in consideration of an extension of credit to
Corporation and for other good and valuable consideration, IMPERIAL BANCORP
("Holder") is entitled to purchase the number of fully paid and non-assessable
shares of the class of securities (the "Shares) of Overland Data, Inc. (the
"Company") at the initial exercise price per Share (the "Warrant Price") all as
set forth above and as adjusted pursuant to Article 2 of this Warrant, subject
to the provisions and upon the terms and conditions set forth of this Warrant.

ARTICLE 1. EXERCISE

    1.1 METHOD OF EXERCISE. Holder may exercise this Warrant by delivering this
Warrant and a duly executed Notice of Exercise in substantially the form
attached as Appendix 1 to the principal office of the Company. Unless Holder is
exercising the conversion right set forth in Section 1.2, Holder shall also
deliver to the Company payment for the aggregate Warrant price for the Shares
being purchased.

    1.2 CONVERSION RIGHT. In lieu of exercising this Warrant as specified in
Section 1.1, Holder may from time to time convert this Warrant, in whole or in
part, into a number of Shares determined by dividing (a) the aggregate fair
market value of the Shares minus the aggregate Warrant Price of such Shares by
(b) the fair market value of one Share. The fair market value of the Shares
shall be determined pursuant to Section 1 3

    1.3 FAIR MARKET VALUE. If the Shares are traded regularly in a public
market, the fair market value of the Shares shall be the closing price of the
Shares reported for the business day immediately before Holder delivers its
Notice of Exercise to the Company. If the Shares are not regularly beaded in a
public market, the Board of Directors of the Company shall determine fair market
value in its reasonable good faith judgment subject to Holder's right to seek
judicial review of such determination

<PAGE>

    1.4 DELIVERY OF CERTIFICATE AND NEW WARRANT. Promptly after Holder 
exercises or converts this Warrant, the Company shall deliver to Holder 
certificates for the Shares acquired and, if this Warrant has not been fully 
exercised or converted and has not expired, a new Warrant representing the 
Shares not so acquired.

    1.5 REPLACEMENT OF WARRANTS. On receipt of evidence reasonably satisfactory
to the Company of the loss, theft, destruction or mutilation of this Warrant
and, in the case of loss, theft or destruction, on delivery of an indemnity
agreement reasonably satisfactory in form and amount to the Company or, in the
case of mutilation, or surrender and cancellation of this Warrant, the Company
at its expense shall execute and deliver, in lieu of this Warrant, a new warrant
of like tenor.

    1.6 REPURCHASE ON SALE, MERGER, OR CONSOLIDATION OF THE COMPANY.

         1.6.1. "ACQUISITION".  For the purpose of this Warrant, 
"Acquisition" means any sale, license, or other disposition of all or 
substantially all of the assets (including intellectual property) of the 
Company, or any reorganization, consolidation, or merger of the Company where 
the holders of the Company's securities before the transaction beneficially 
own less than 50% of the outstanding voting securities of the surviving 
entity after the transaction.

         1.6.2. ASSUMPTION OF WARRANT. If upon the closing of any Acquisition 
the successor entity assumes the obligations of this Warrant, then this 
Warrant shall be exercisable for the same securities, cash, and property as 
would be payable for the Shares issuable upon exercise of the unexercised 
portion of this Warrant as if such Shares were outstanding on the record date 
for the Acquisition and subsequent closing. The Warrant Price shall be 
adjusted accordingly. The Company shall use reasonable efforts to cause the 
surviving corporation to assume the obligations of this Warrant.

         1.6.3. NONASSUMPTION. If upon the closing of any acquisition the 
successor entity does not assume the obligations of his Warrant and Holder 
has not otherwise exercised this Warrant in full, then the unexercised 
portion of this Warrant shall be deemed to have been automatically converted 
pursuant to Section 1.2 and thereafter Holder shall participate in the 
acquisition on the same terms as other holders of the same class of 
securities of the Company.

ARTICLE 2. ADJUSTMENTS TO THE SHARES.

    2.1 STOCK DIVIDENDS, SPLITS, ETC. If the Company declares or pays a
dividend on its common stock payable in common stock, or other securities,
subdivides the outstanding common stock into a greater amount of common stock,
then upon exercise of this Warrant, for each Share acquired, Holder shall
receive, without cost to Holder, the total number and kind of securities to
which Holder would have been entitled had Holder owned the Shares of record as
of the date the dividend or subdivision occurred

<PAGE>

    2.2 RECLASSIFICATION, EXCHANGE OR SUBSTITUTION. Upon any reclassification,
exchange, substitution, or other event that results in a change of the number
and/or class of the securities issuable upon exercise or conversion of this
Warrant, Holder shall be entitled to receive, upon exercise or conversion of
this Warrant, the number and kind of securities and property that Holder would
have received for the Shares if this Warrant had been exercised immediately
before such reclassification, exchange, substitution, or other event. The
Company or its successor shall promptly issue to Holder a new Warrant for such
new securities or other property. The new Warrant shall provide for adjustments
which shall be as nearly equivalent as may be practicable to the adjustments
provided for in this Article 2 including, without limitation, adjustments to the
Warrant Price and to the number of securities or property issuable upon exercise
of the new Warrant. The provisions of this Section 2.2 shall similarly apply to
successive reclassifications, exchanges, substitutions, or other events.

    2.3 ADJUSTMENTS FOR COMBINATIONS, ETC. If the outstanding Shares are
combined or consolidated, by reclassification or otherwise, into a lesser number
of shares, the Warrant Price shall be proportionately increased.

    2.4 ADJUSTMENTS FOR DILUTING ISSUANCES. The Warrant Price and the number of
Shares issuable upon exercise of this Warrant shall be subject to adjustment,
from time to time, in the manner set forth on Exhibit A in the event of Diluting
Issuances (as defined on Exhibit A).

    2.5 NO IMPAIRMENT. The Company shall not, by amendment of its Articles of
Incorporation or through a reorganization, transfer of assets, consolidation,
merger, dissolution, issue, or sale of securities or any other voluntary action,
avoid or seek to avoid the observance or performance of any of the terms to be
observed or performed under this Warrant by the Company, but shall at all times
in good faith assist in carrying out all the provisions of this Article 2 and in
taking all such action as may be necessary or appropriate to protect Holder's
rights under this Article against impairment. If the Company takes any corporate
action affecting the Shares other than as specifically described above that
materially and adversely affects Holder's rights under this Warrant, the Warrant
Price shall be adjusted downward and the number of Shares issuable upon exercise
of this Warrant shall be adjusted upward in such a manner that the aggregate
Warrant Price of this Warrant is unchanged.

    2.6 CERTIFICATE AS TO ADJUSTMENTS. Upon each adjustment of the Warrant
Price, the Company at its expense shall promptly compute such adjustment, and
furnish Holder with a certificate of its Chief Financial Officer setting forth
such adjustment and the facts upon which such adjustment is based. The Company
shall, upon written request, furnish Holder a certificate setting forth the
Warrant Price in effect upon the date thereof and the series of adjustments
leading to such Warrant Price.

Statement of Intent

It is IBM's intention to do business with Suppliers who remain competitive in
providing IBM with leading-edge technology at favorable prices on acceptable
terms and conditions.  Accordingly, from time to time, IBM intends to assess
Suppliers' competitiveness in terms of pricing, continuity of supply, quality
improvement, and cost reduction, and to notify Supplier if IBM determines that
the Supplier is not competitive with its fully qualified competitors so that the
Supplier can remedy the situation.

this Agreement and the Work Authorizations issued under Section 3.0 below.

2.0 Term and Termination:

This Agreement shall commence on the date of execution by the parties and shall
continue in full force and effect for a period of five  years unless earlier
terminated as provided in this Agreement.  Either party may terminate this
Agreement for material breach of the other party upon sixty (60) days written
notice.

3.0 Work Authorization:

Only a Work Authorization issued by IBM or its subsidiaries (i.e. a Purchase
Order, or other document or transaction defined in the PSPL as a Work
Authorization), in either electronic or hard copy form, provides authorization
to the Supplier to perform any work or produce any products under this
Agreement.  Only procurement personnel of IBM or its subsidiaries have the
authority to issue Work Authorizations or direct work activity under the terms

                                 IMPERIAL BANK
                                  MEMBER FDIC

                          SECURITY AND LOAN AGREEMENT
                             (ACCOUNTS RECEIVABLE)

1.   This Agreement is entered into between OVERLAND DATA INC., a Corporation 
     (herein called "Borrower") and IMPERIAL BANK (herein called "Bank"):

                         80.000 % of Eligible Accounts

     and in no event more than   $5,000,000.00

2.   The amount of each loan made by Bank to Borrower hereunder shall be 
     debited to the loan ledger account of Borrower maintained by Bank (herein 
     called "Loan Account") and Bank shall credit the Loan Account with all 
     loan repayments made by Borrower.  Borrower promises to pay Bank(a) the 
     unpaid balance of Borrower's Loan Account on demand and (b) on or before 
     the tenth day of each month, interest on the average daily unpaid balance 
     of the Loan Account during the immediately preceding month at the rate of

     interest which Bank has announced as its prime lending rate ("Prime Rate") 
     which shall vary concurrently with any change in such Prime Rate. Interest 
     shall be computed at the above rate on the basis of the actual number of 
     days during which the principal balance of the loan account is outstanding 
     divided by 360, which shall for Interest computation purposes be 
     considered one year. Bank at its option may demand payment of any or all 
     of the amount due under the Loan Account including accrued but unpaid 
     interest at any time. Such notice may be given verbally or in writing and 
     should be effective upon receipt by Borrower.  The amount of interest 
     payable each month by Borrower shall not be less than a minimum monthly 
     charge of $0.00.  Bank is hereby authorized to charge Borrower's deposit 
     account(s) with Bank for all sums due Bank under this Agreement.

3.   Requests for loans hereunder shall be in writing duly executed by 
     Borrower in a form satisfactory to Bank and shall contain a certification 
     setting forth the matters referred to in Section 1 which shall disclose 
     that Borrower is entitled to the amount of loan being requested.

4.   As used in this Agreement, the following terms shall have the following 
     meanings:

<PAGE>

     A.   "Accounts" means any right to payment for goods sold or leased, or 
          to be sold or to be leased, or for services rendered or to be 
          rendered no matter how evidenced, including accounts receivable, 
          contract rights, chattel paper, instruments, purchase orders, notes, 
          drafts, acceptances, general intangibles and other forms of 
          obligations and receivables.

     B.   "Collateral" means any and all personal property of Borrower which 
          is assigned or hereafter is assigned to Bank as security or in which 
          Bank now has or hereafter acquires a security interest.

     C.   "Eligible Accounts"  means all of Borrower(s) Accounts excluding, 
          however, (1) all Accounts under which payment is not received within 
          90 days from any invoice date, (2) all Accounts against which the 
          account debtor or any other person obligated to make payment thereon 
          asserts any defense, offset, counterclaim or other right to avoid or 
          reduce the liability represented by the account and (3) any Accounts 
          if the account debtor or any other person liable in connection 
          therewith is insolvent, subject to bankruptcy or receivership 
          proceedings or has made an assignment for the benefit of creditors or 
          whose credit standing is unacceptable to Bank and Bank has so 
          notified Borrower. Eligible Accounts shall only include such accounts 
          as Bank in its sole discretion shall determine are eligible from time 
          to time.

5.   Borrower hereby assigns to Bank all Borrower's present and future 
     Accounts, including all proceeds due thereunder, all guaranties and 
     security therefor, and hereby grants to Bank a continuing security 
     interest in all moneys in the Collateral Account referred to Section 6 
     hereof, as security for any and all obligations of Borrower to Bank, 
     whether now owing or hereafter incurred and whether direct, indirect, 
     absolute or contingent. So long as Borrower is indebted to Bank or Bank is 
     committed to extend credit to Borrower, Borrower will execute and deliver 
     to Bank such assignments, including Bank's standard forms of Specific or 
     General Assignment covering individual Accounts, notices, financing 
     statements, and other documents and papers as Bank may require in order to

     paragraph 10, Borrower will collect with diligence all Borrower's Accounts 
     provided that no legal action shall be maintained thereon or in connection 
     therewith without Bank's prior written consent. Any collection of Accounts

     Borrower shall keep all such collections separate and apart from all other 
     funds and property so as to be capable of identification as the property 
     of Bank and deliver said collections daily to Bank in the identical form 
     received. The proceeds of such collections when received by Bank may be 
     applied by Bank directly to the payment of Borrower's Loan Account or any 
     other obligation secured hereby.  Any credit given by Bank upon receipt of 
     said proceeds shall be conditional credit subject to collection. Returned 
     Items at Bank's option may be charged to Borrower's general account.  All 
     collections of the Accounts shall be set forth on an itemized schedule, 
     showing the name of the account debtor, the amount of each payment and 
     such other information as Bank may request.

7.   Until Bank exercises its rights to collect the Accounts pursuant to 
     paragraph 10, Borrower may continue its present policies with respect to 
     returned merchandise and adjustments.  However, Borrower shall immediately 
     notify Bank of all cases involving returns, repossessions, and loss or 
     damage of or to merchandise represented by the Accounts and, of any 
     credits, adjustments or disputes arising in connection with the goods or 
     services represented by the Accounts and, in any of such events, Borrower 
     will immediately pay to Bank from its own funds (and not from the proceeds 
     of Accounts or Inventory) for application to Borrower's Loan Account or 
     any other obligation secured hereby the amount of any credit for such 
     returned or repossessed merchandise and adjustments made to any of the 
     Accounts.

8.   Borrower represents and warrants to Bank: (i) If Borrower is a

     the account debtor; (iv) That there are or will be no defenses, 
     counterclaims, or setoffs which may be asserted against the Accounts; and

     may in any way affect the value of the Collateral or the rights and 
     remedies of Bank in respect thereto; (v) Reimburse Bank upon demand for 
     any and all legal costs, including reasonable attorneys' fees, and other

     Accounts and may give notice of assignment to any and all account debtors, 
     and Borrower does hereby make, constitute and appoint Bank its 
     irrevocable, true and lawful attorney with power to receive, open and

any reason Lessor cannot deliver possession of the Premises to Lessee on said
date, Lessor shall not be subject to any liability therefor, nor shall such
failure affect the validity of this Lease or the obligations of Lessee hereunder
or extend the term hereof, but in such case, Lessee shall not be obligated to
pay rent or perform any other obligation of Lessee under the terms of this
Lease, except as may be otherwise provided in this Lease, until possession of
the Premises is tendered to Lessee; provided, however, that if Lessor  shall not
have  delivered  possession of the Premises within sixty (60) days from said
commencement date. Lessee may, at Lessee's option, by notice in writing to
Lessor within ten (10) days thereafter, cancel this Lease, in which event the
parties shall be discharged from all obligations hereunder; provided further,

said ten (10) day period, Lessee's right to cancel this Lease hereunder shall
terminate and be of no further force or effect.

commencement date, such occupancy shall be subject to all provisions of this

pay rent for such period at the initial monthly rates set forth below.

to such other persons or at such other places as Lessor may designate in
writing.

    4.2 Operating Expenses.  Lessee shall pay to Lessor during the term hereof,
in addition to the Base Rent, Lessee's Share, as hereinafter defined, of all
Operating Expenses, as hereinafter defined, during each calendar year of the
term of this Lease, in accordance with the following provisions:

    (a) "Lessee's Share" is defined, for purposes of this Lease, as  54.2 
percent.

    (b) "Operating Expenses" is defined, for purposes of this Lease, as all
costs incurred by Lessor, if any, for:

        (i) The operation, repair and maintenance, in neat, clean, good order 
and condition, of the following:

facilities or to provide those services unless the Industrial Center already has
the same, Lessor already provides the services, or Lessor has agreed elsewhere
in the Lease to provide the same or some of them.

<PAGE>


 
    (d)  Lessee's Share of Operating Expenses shall be payable by Lessee within
ten (10) days after a reasonably detailed statement of actual expenses is
presented to Lessee by Lessor. At Lessor's option, however, an amount may be
estimated by Lessor from time to time of Lessee's Share of annual Operating
Expenses and the same shall be payable monthly or quarterly, as Lessor shall
designate, during each twelve-month period of the Lease term, on the same day as
the Base Rent is due hereunder.  In the event that Lessee pays Lessor's estimate
of Lessee's Share of Operating Expenses as aforesaid, Lessor shall deliver to
Lessee within sixty (60) days after the expiration of each calendar year a
reasonably detailed statement showing Lessee's Share of the actual Operating
Expenses incurred during the preceding year.  If Lessee's payments under this
paragraph 4.2(d) during said preceding year exceed Lessee's Share as indicated
on said statement, Lessee shall be entitled to credit the amount of such
overpayment against Lessee's Share of Operating Expenses next falling due.  If
Lessee's payments under this paragraph during said preceding year were less than
Lessee's Share as indicated on said statement, Lessee shall pay to Lessor the
amount of the deficiency within ten (10) days after delivery by Lessor to Lessee
of said statement.

5.  Security Deposit.  Lessee shall  deposit with Lessor upon execution 
hereof $36,828.40 as security for Lessee's faithful performance of Lessee's 
obligations hereunder.  If Lessee fails to pay rent or other charges due 
hereunder, or otherwise defaults with respect to any provision of this Lease, 
Lessor may use, apply or retain all or any portion of said deposit for the 
payment of any rent or other charge in default or for the payment of any 
other sum to which Lessor may become obligated by reason of Lessee's default, 
or to compensate Lessor for any loss or damage which Lessor may suffer 
thereby.  If Lessor so uses or applies all or any portion of said deposit, 
Lessee shall within ten (10) days after written demand therefor deposit cash 
with Lessor in an amount sufficient to restore said deposit to the full 
amount then required of Lessee.  If the monthly rent shall, from time to 
time, increase during the term of this Lease, Lessee shall, at the time of 
such increase, deposit with Lessor additional money as a security deposit so 
that the total amount of the security deposit held by Lessor shall at all 
times bear the same proportion to the then current Base Rent as the initial 
security deposit bears to the initial Base Rent set forth in paragraph 4.  
Lessor shall not be required to keep said security deposit separate from its 
general accounts.  If Lessee performs all of Lessee's obligations hereunder, 
said deposit, or so much thereof as has not theretofore been applied by 
Lessor, shall be returned, without payment of interest or other increment for 
its use, to Lessee (or, at Lessor's option, to the last assignee, if any, of 
Lessee's interest hereunder) at the expiration of the term hereof, and after 
Lessee has vacated the Premises.  No trust relationship is created herein 
between Lessor and Lessee with respect to said Security Deposit.

6.  Use.

    6.1  Use.  The Premises shall be used and occupied only for GENERAL OFFICE,
AND LIGHT MANUFACTURING OF COMPUTER TYPE DRIVES AND RELATED ACCESSORIES   or any
other use which is reasonably comparable and for no other purpose.

    6.2  Compliance with Law.

         (a)  Lessor warrants to Lessee that the Premises, in the state
existing on the date that the Lease term commences, but without regard to the
use for which Lessee will occupy the Premises, does not violate any covenants or
restrictions of record, or any applicable building code, regulation or ordinance
in effect on such Lease term commencement date.  In the event it is determined
that this warranty has been violated, then it shall be the obligation of the
Lessor,  to promptly, at Lessor's sole cost and expense, rectify any such
violation.  The warranty contained in this paragraph 6.2(a) shall be of no force
or effect if, prior to the date of this Lease, Lessee was an owner or occupant
of the Premises and, in such event, Lessor shall correct any such violation
Lessee's sole cost.

         (b)  Except as provided in paragraph 6.2(a) Lessee shall, at Lessee's
expense, promptly comply with all applicable statutes, ordinances, rules
regulations, orders, covenants and restrictions of record, and requirements of
any fire insurance underwriters or rating bureaus, now in effect or which may
hereafter come into effect, whether or not they reflect a change in policy from
that now existing, during the term or any part of the term hereof, relating in
any manner to the Premises and the occupation and use by Lessee of the Premises
and of the Common Areas.  Lessee shall not use nor permit the use of the
Premises of the Common Areas in any manner that will tend to create waste or a
nuisance or shall tend to disturb other occupants of the Industrial Center.

    6.3  Condition of Premises.

         (a)  Lessor shall deliver the Premises to Lessee clean and free of 
debris on the Lease commencement date (unless Lessee is already in 
possession) and Lessor warrants to Lessee that the plumbing, lighting, air 
conditioning, heating, and loading doors in the Premises shall be in good 
operating condition on the Lease commencement date.  In the event that it is 
determined that this warranty has been violated, then it shall be the 
obligation of Lessor, after receipt of written notice from Lessee setting 
forth with specificity the nature of the violation, to promptly, at Lessor's 
sole cost, rectify such violation. Lessee's failure to give such written 
notice to Lessor within one hundred eighty (180) days after the Lease 
commencement date shall cause the conclusive presumption that Lessor has 
complied with all of Lessor's obligations hereunder. The warranty contained 
in this paragraph 6.3(a) shall be of no force or effect if prior to the date 
of this Lease, Lessee was an owner or occupant of the Premises.

         (b)  Except as otherwise provided in this Lease, Lessee hereby accepts
the Premises in their condition existing as of the Lease commencement date or
the date that Lessee takes possession of the Premises, whichever is earlier,
subject to all applicable zoning, municipal, county and state laws, ordinances
and regulations governing and regulating the use of the Premises, and any
covenants or restrictions of record, and accepts this Lease subject thereto and
to all matters disclosed thereby and by any exhibits attached hereto.  Lessee
acknowledges that neither Lessor nor Lessor's agent has made any representation
or warranty as to the present or future suitability of the Premises for the
conduct of Lessee's business.

7.  Maintenance, Repairs, Alternations and Common Area Services.

    7.1  Lessor's Obligations.  Subject to the provisions of paragraphs 4.2
(Operating Expenses), 6(Use), 7.2 (Lessee's Obligations) and 9 (Damage or
Destruction) and except for damage caused by any negligent or intentional act or
omission of Lessee, Lessee's employees, suppliers , shippers, customers, or
invitees, in which event Lessee shall repair the damage, Lessor, at Lessor's
expense, subject to reimbursement pursuant to paragraph 4.2, shall keep in good
condition and repair the foundations, exterior walls, structural condition of
interior bearing walls, and roof of the Premises, as well as the parking lots,
walkways, driveways, landscaping, fences, signs and utility installations of the
Common Areas and all parts thereof, as well as providing the services for which
there is an Operating Expense pursuant to paragraph 4.2.  Lessor shall not,
however, be obligated to paint the exterior or interior surface of exterior
walls, nor shall Lessor be  required to maintain, repair or replace windows,
doors or plate glass of the Premises.  Lessor shall have no obligation to make
repairs under  paragraph 7.1 until a reasonable time after receipt of written
notice from lessee of the need for such repairs.  Lessee expressly waives the
benefits of any statute now or hereafter in effect which would otherwise afford
Lessee the right to make repairs at Lessor's expense or to terminate this Lease
because of Lessor's failure to keep the Premises in  good order, condition and
repair.   Lessor shall not be liable for damages or loss of any kind or nature
by reason of Lessor's failure to furnish any Common Area Services when such
failure is caused by accident, breakage, repairs, strikes, lockout, or other
labor disturbance or disputes of any character, or by any other cause beyond the
reasonable control of Lessor.

    7.2  Lessee's Obligations

         (a)  Subject to the provisions of paragraphs 6 (Use), 7.1 (Lessor's
Obligations), and 9 (Damage or Destruction), Lessee , at Lessee's expense, shall
keep in good order, condition and repair the Premises and every part thereof
(whether or not the damaged portion of the Premises or the means of repairing
the same are reasonably or readily accessible to Lessee) including, without
limiting the generality of the foregoing plumbing, heating, ventilating and air
conditioning systems (Lessee shall procure and maintain, at Lessee's expense, a
ventilating air conditioning system maintenance contract), electrical and
lighting facilities and equipment within the Premises, fixtures, interior walls
and interior surfaces of exterior walls, ceilings, windows, doors, plate glass,
and skylights located within the Premises.  Lessor reserves the right to procure
and maintain the ventilating and air conditioning system maintenance contract
and if Lessor so elects, Lessee shall reimburse Lessor, upon demand, for the
cost thereof.

         (b)  If Lessee fails to perform Lessee's obligations under this
paragraph 7.2 or under any other paragraph of this Lease, Lessor may enter upon
the Premises after ten (10) days' prior written noticed to Lessee (except in the
case of emergency, in which no notice shall be required), perform such
obligations on Lessee's behalf and put the Premises in good order, condition and
repair, and the cost thereof together with interest thereon at the maximum rate
then allowable by law shall be due and payable as additional rent to Lessor
together with Lessee's next Base Rent installment.

         (c)  On the last day of the term hereof, or on any sooner termination,
Lessee shall surrender the Premises to Lessor in the same condition as received,
ordinary wear and tear excepted, clean and free of debris.  Any damage or
deterioration of the Premises shall not be deemed ordinary wear and tear if the
same could have been prevented by good maintenance practices.  Lessee shall
repair any damage to the Premises occasioned by the installation or removal of
Lessee's trade fixtures, alterations, furnishings and equipment. 
Notwithstanding anything to the contrary otherwise stated in this Lease, Lessee
shall leave the air lines, power panels, electrical distribution systems,
lighting fixtures, space heaters, air conditioning, plumbing and fencing on the
Premises in good operating condition. 

    7.3  Alterations and Additions.

         (a)  Lessee shall not, without Lessor's prior written consent make any
alterations, improvements, additions, or Utility Installation in , on or about
the Premises, or the Industrial Center, except for nonstructural alterations to
the Premises not exceeding $50,000 in cumulative costs, during the term of this
Lease.  In any event, whether or not  in excess of $50,000 in cumulative costs,
Lessee shall make no change or alteration to the exterior of the Premises nor
the exterior of the Building nor the Industrial Center without Lessor's prior
written consent.  As used in this paragraph 7.3 the term "Utility Installation"
shall mean carpeting, window coverings, air lines, power panels, electrical
distribution systems, lighting fixtures, space heaters, air conditioning,
plumbing, and fencing.   Lessor may require that Lessee remove any or all of
said alterations, improvements, additions or Utility Installations except those
improvements located in the Premises prior to lease execution at the expiration
of the term, and restore the Premises and the Industrial Center to their prior
condition. Lessor may require Lessee to provide Lessor, at Lessee's sole cost
and expense, a lien and completion bond in an amount equal to one and one-half
times the estimated cost of such improvements, to insure Lessor against any
liability for mechanic's and materialmen's liens and to insure completion of the
work.  Should Lessee make any alterations, improvements, additions or Utility
Installations without the prior approval of Lessor, Lessor may, at any time
during the term of this Lease, require that Lessee remove any or all of the
same.

         (b)  Any alterations, improvements, additions or Utility Installations
in or about the Premises or the Industrial Center that Lessee shall desire to
make and which requires the consent of the Lessor shall be presented to Lessor
in written form, with proposed detailed plans.  If Lessor shall give its
consent, the consent shall be deemed conditioned upon Lessee acquiring a permit
to do so from appropriate governmental agencies, the furnishing of a copy
thereof to Lessor prior to the commencement of the work and the compliance by
Lessee of all conditions of said permit in a prompt and expeditious manner.

         (c)  Lessee shall pay, when due, all claims for labor or materials
furnished or alleged to have been furnished to or for Lessee at or for use in
the Premises, which claims are or may be secured by any mechanic's or
materialmen's lien against  the Premises, or the Industrial Center, or any
interest therein.  Lessee shall give Lessor not less than ten (10) days' notice
prior to the commencement of any work in the Premises, and Lessor shall have the
right to post notices of non-responsibility in or on the Premises or the
Building as provided by law.  If Lessee shall, in good


<PAGE>


faith, contest the validity of any such lien, claim or demand, then Lessee 
shall, at its sole expense defend itself and Lessor against the same and 
shall pay and satisfy any such adverse judgment that may be rendered thereon 
before the enforcement thereof against the Lessor or the Premises or the 
Industrial Center, upon the condition that if Lessor shall require, Lessee 
shall furnish to Lessor a surety bond satisfactory to Lessor in an amount 
equal to such contested lien claim or demand indemnifying Lessor against 
liability for the same and holding the Premises and the Industrial Center 
free from the effect of such lien or claim. In addition, Lessor may require 
Lessee to pay Lessor's attorneys' fees and costs in participating in such 
action if Lessor shall decide it is to Lessor's best interest to do so.

         (d)  All alterations, improvements, additions and Utility
Installations (whether or not such Utility Installations constitute trade
fixtures of Lessee), which may be made on the Premises, shall be the property of
Lessor and shall remain upon and be surrendered with the Premises at the
expiration of the Lease term, unless Lessor requires their removal pursuant to
paragraph 7.3(a).  Notwithstanding the provisions of this paragraph 7.3(d),
Lessee's machinery and equipment, other than that which is affixed to the
Premises so that it cannot be removed without material damage to the Premises,
and other than Utility Installations, shall remain the property of Lessee and
may be removed by Lessee subject to the provisions of paragraph 7.2.

    7.4  Utility Additions.  Lessor reserves the right to install new or
additional utility facilities throughout the Building and the Common Areas for
the benefit of Lessor or Lessee, or any other lessee of the Industrial Center,
including, but not by way of limitation, such utilities as plumbing, electrical
systems, security systems, communication systems, and fire protection and
detection systems, so long as such installations do not unreasonably interfere
with Lessee's use of the Premises.

8.  Insurance:  Indemnity.

    8.1  Liability Insurance - Lessee.  Lessee shall, at Lessee's expense,
obtain and keep in force during the term of this Lease a policy of Combined
Single Limit Bodily Injury and Property Damage insurance insuring Lessee and
Lessor against any liability arising out of the use, occupancy or maintenance of
the Premises and the Industrial Center.  Such insurance shall be in an amount
not less than $500,000.00 per occurrence.  The policy shall insure performance
by Lessee of the indemnity provisions of this paragraph 8.  The limits of said
insurance shall not, however, limit the liability of Lessee hereunder.

    8.2  Liability Insurance - Lessor.  Lessor shall obtain and keep in force
during the term of this Lease a policy of Combined Single Limit Bodily Injury 
and Property Damage Insurance, insuring Lessor, but not Lessee, against any
liability arising out of the ownership, use, occupancy or maintenance of the
Industrial Center in an amount not less than $500,000.00 per occurrence.

    8.3  Property Insurance.  Lessor shall obtain and keep in force during 
the term of this Lease a policy or policies of insurance covering loss or 
damage to the Industrial Center improvements, but not Lessee's personal 
property, fixtures, equipment or tenant improvements, in an amount not to 
exceed the full replacement value thereof, as the same may exist from time to 
time, providing protection against all perils included within the 
classification of fire extended coverage, vandalism, malicious mischief, 
flood (in the event the same is required by a lender having a lien on the 
Premises) special extended perils ("all risk", as such term is used in the 
insurance industry), plate glass insurance and such other insurance as Lessor 
deems advisable.  In addition, Lessor shall obtain and keep in force, during 
the term of this Lease, a policy of rental value insurance covering a period 
of one year, with loss payable to Lessor, which insurance shall also cover 
all Operating Expenses for said period. In the event that the Premises shall 
suffer an insured loss as defined in paragraph 9.1(g) hereof, the deductible 
amounts under the casualty insurance policies relating to the Premises shall 
be paid by Lessee, not to exceed $10,000.

    8.4  Payment of Premium Increase.

         (a)  After the term of this Lease has commenced, Lessee shall not be
responsible for paying Lessee's Share of any increase in the property insurance
premium for the Industrial Center specified by Lessor's insurance carrier as
being caused by the use, acts or omissions of any other lessee of the Industrial
Center, or by the nature of such other lessee's occupancy which create an
extraordinary or unusual risk.

         (b)  Lessee, however, shall pay the entirety of any increase in the
property insurance premium for the Industrial Center over what it was
immediately prior to the commencement of the term of this Lease if the increase
is specified by Lessor's insurance carrier as being caused by the nature of
Lessee's occupancy or any act or omission of Lessee.

    8.5  Insurance Policies.  Insurance required hereunder shall be companies
holding a "General Policyholders Rating" of at least B plus, or such other
rating as may be required by a lender having a lien on the Premises, as set
forth in the most current issue of "Best's Insurance Guide".  Lessee shall not
do or permit to be done anything which shall invalidate the insurance policies
carried by Lessor.  Lessee shall deliver to Lessor copies of liability insurance
policies required under paragraph 8.1 or certificates evidencing the existence
and amounts of such insurance within seven (7) days after the commencement date
of this Lease.  No such policy shall be cancellable or subject to reduction of
coverage or other modification except after thirty (30) days prior written
notice to Lessor.  Lessee shall, at least thirty (30) days prior to the
expiration of such policies, furnish Lessor with renewals or "binders thereof.

    8.6  Waiver of Subrogation.  Lessee and Lessor each hereby release and
relieve the other, and waive their entire right of recovery against the other
for loss or damage arising out of or incident to the perils insured against
which perils occur in, on or about the Premises, whether due to the negligence
of Lessor or Lessee or their agents, employees, contractors and/or invitees. 
Lessee and Lessor shall, upon obtaining the policies of insurance required
hereunder, give notice to the insurance carrier or carriers that the foregoing
mutual waiver of subrogation is contained in this Lease.

<PAGE>

    8.7  Indemnity.  Lessee shall indemnify and hold harmless Lessor from and
against any and all claims arising from Lessee's use of the Industrial Center,
or from the conduct of Lessee's business or from any activity, work or things
done, permitted or suffered by Lessee in or about the Premises or elsewhere and
shall further indemnify and hold harmless Lessor from and against any and all
claims arising from any breach default in the performance of any obligation on
Lessee's part to be performed under the terms of this Lease, or arising from any
act or omission  of Lessee, or any of Lessee's agents, contractors, or
employees, and from and against all costs, attorney's fees, expenses and
liabilities incurred in the defense of any such claim or any action or
proceeding brought thereon; and in case any action or proceeding be brought
against Lessor by reason of any such claim.  Lessee upon notice from Lessor
shall defend the same at Lessee's expense by counsel reasonably satisfactory to
Lessor and Lessor shall cooperate with Lessee in such defense.  Lessee, as a
material part of the consideration to Lessor, hereby assumes all risk of damage
to property of Lessee or injury to persons, in, upon or about the Industrial
Center arising from any cause and Lessee hereby waives all claims in respect
thereof against Lessor.

    8.8  Exemption of Lessor from Liability.  Lessee hereby agrees that Lessor
shall not be liable for injury to Lessee's business or any loss of income
therefrom or for damage to the goods, wares, merchandise or other property of
Lessee, Lessee's employees, invitees, customers, or any other person in or about
the Premises or the Industrial Center, nor shall Lessor be liable for injury to
the person of Lessee, Lessee's employees, agents or contractors, whether such
damage or injury is caused by or results from fire, steam, electricity, gas,
water or rain, or from the breakage, leakage, obstruction or other defects of
pipes, sprinklers, wires, appliances, plumbing, air conditioning or lighting
fixtures, or from any other cause, whether said damage or injury results from
conditions arising upon the Premises or upon other portions of the Industrial
Center, or from other sources or places and regardless of whether the cause of
such damage or injury or the means of repairing the same is inaccessible to
Lessee.  Lessor shall not be liable for any damages arising from any act or
neglect of any other lessee, occupant or user of the industrial Center, nor from
the failure of Lessor to enforce the provisions of any other lease of the
Industrial Center.

restoration within ninety (90) days after such obligation shall accrue, Lessee

10. Real Property Taxes

    10.1 Payment of Taxes.  Lessor shall pay the real property tax, as defined
in paragraph 10.3, applicable to the Industrial Center subject to reimbursement
by Lessee of Lessee's Share of such taxes in accordance with the provisions of
paragraph 4.2, except as otherwise provided in paragraph 10.2.

    10.2 Additional Improvements.  Lessee shall not be responsible for paying
Lessee's Share of any increase in real property tax specified in the tax
assessor's records and work sheets as being caused by additional improvements
placed upon the Industrial Center by other lessees or by Lessor for the
exclusive enjoyment of such other lessees.  Lessee shall, however, pay to Lessor
at the time that Operating Expenses are payable under paragraph 4.2(c) the
entirety of any increase in real property tax if assessed solely by reason of
additional improvements placed upon the Premises by Lessee or at Lessee's
request.

    10.3 Definition of "Real Property Tax".  As used herein, the term "real
property tax" shall include any form of real estate tax or assessment, general,
special, ordinary or extraordinary, and any license fee, commercial rental tax,
improvement bond or bonds, levy or tax (other than inheritance, personal income
or estate taxes) imposed on the Industrial Center or any portion thereof by any
authority having the direct or indirect power to tax, including any city,
county, state or federal government, or any school, agricultural, sanitary,
fire, street, drainage or other improvement district thereof, as against any
legal or equitable interest of Lessor in the Industrial Center or in an y
portion thereof, as against Lessor's right to rent or other income therefrom,
and as against Lessor's business of leasing the Industrial Center.  The term
"real property tax" shall also include any tax, fee, levy, assessment or charge
(i) in substitution of, partially or totally, any tax, fee, levy, assessment or
charge hereinabove included within the definition of "real property

<PAGE>


tax", or (ii) the nature of which was hereinbefore included within the 
definition of "real property tax", or (iii) which is imposed for a service or 
right not charged prior to June 1, 1978, or , if previously charged, has been 
increased since June 1, 1978, or (iv) which is imposed as a result of a 
transfer, either partial or total, of Lessor's interest in the Industrial 
Center or which is added to a tax or charge hereinbefore included within the 
definition of real property tax by reason of such transfer, or (v) which is 
imposed by reason of this transaction , any modifications or changes hereto, 
or any transfers hereof.

    10.4 Joint Assessment.  If the Industrial Center is not separately
assessed, Lessee's Share of the real property tax liability shall be an
equitable proportion of the real property taxes for all of the land and
improvements included within the tax parcel assessed, such proportion to be
determined by Lessor from the respective valuations assigned in the assessor's
work sheets or such other information as may be reasonably available.  Lessor's
reasonable determination thereof, in good faith, shall be conclusive.

    10.5 Personal Property Taxes.

         (a)  Lessee shall pay prior to delinquency all taxes assessed against
and levied upon trade fixtures, furnishings, equipment and all other personal
property of Lessee contained in the Premises or elsewhere.  When possible,
Lessee shall cause said trade fixtures, furnishings, equipment and all other
personal property to be assessed and billed separately from the real property of
Lessor.

         (b)  If any of Lessee's said personal property shall be assessed with
Lessor's real property, Lessee shall pay to Lessor the taxes attributable to
Lessee within ten (10) days after receipt of a written statement setting forth
the taxes applicable to Lessee's property.


11. Utilities.  Lessee shall pay for all water, gas, heat, light, power,
telephone and other utilities and services supplied to the Premises, together
with any taxes thereon.  If any such services are not separately metered to the
Premises, Lessee shall pay at Lessor's option, either Lessee's Share or a
reasonable proportion to be determined by Lessor of all charges jointly metered
with other premises in the Building.

12. Assignment and Subletting.

    12.1 Lessor's Consent Required*.  Lessee shall not voluntarily or by
operation of law assign, transfer, mortgage, sublet, or otherwise transfer or
encumber all or any part of Lessee's interest in the Lease or in the Premises,
without Lessor's prior written consent, which Lessor shall not unreasonably
withhold.  Lessor shall respond to Lessee's request for consent hereunder in a
timely manner and any attempted assignment, transfer, mortgage, encumbrance or
subletting without such consent shall be void, and shall constitute a breach of
this Lease without the need for notice to Lessee under paragraph 13.1.  *See
addendum #59.

    12.2 Lessee Affiliate.  Notwithstanding the provisions of paragraph 12.1
hereof, Lessee may assign or sublet the Premises, or any portion thereof,
without Lessor's consent, to any corporation which controls, is controlled by or
is under common control with Lessee, or to any corporation resulting from the
merger or consolidation with Lessee, or to any person or entity which acquires
all the assets of Lessee as a going  concern of the business that is being
conducted on the Premises, all of which are referred to as "Lessee Affiliate",
provided that before such assignment shall be effective said assignee shall
assume, in full, the obligations of Lessee under this Lease.  Any such
assignment shall not, in any way, affect or limit the liability of Lessee under
the terms of this Lease even if after such assignment or subletting the terms of
this Lease are materially changed or altered without the consent of Lessee, the
consent of whom shall not be necessary.

    12.3 Terms and Conditions of Assignment.  Regardless of Lessor's consent, 
no assignment shall release Lessee of Lessee's obligations hereunder or alter 
the primary liability of Lessee to pay the Base Rent and Lessee's Share of 
Operating Expenses, and to perform all other obligations to be performed by 
Lessee hereunder.  Lessor may accept rent from any person other than Lessee 
pending approval or disapproval of such assignment.  Neither a delay in the 
approval or disapproval of such assignment nor the acceptance of rent shall 
constitute a waiver or estoppel of Lessor's right to exercise its remedies 
for the breach of any of the terms or conditions of this paragraph 12 of this 
Lease. Consent to one assignment shall not be deemed consent to any 
subsequent assignment.  In the event of default by any assignee of Lessee or 
any successor of Lessee, in the performance of any of the terms hereof, 
Lessor may proceed directly against Lessee without the necessity of 
exhausting remedies against said assignee.  Lessor may consent to the 
subsequent assignments of this Lease or amendments or modifications to this 
Lease with assignees of Lessee, without notifying Lessee, or any successor of 
Lessee, and without obtaining its or their consent thereto and such action 
shall not relieve Lessee of liability under this Lease.

    12.4 Terms and Conditions Applicable to Subletting.  Regardless of Lessor's
consent, the following terms and conditions shall apply to any subletting by
Lessee of all or any part of the Premises and shall be included in subleases:

         (a)  Lessee hereby assigns and transfers to Lessor all of Lessee's
interest in all rentals and income arising from any sublease heretofore or
hereafter made by Lessee, and Lessor may collect such rent and income and apply
same toward Lessee's obligations under this Lease; provided, however, that until
a default shall occur in the performance of Lessee's obligations under this
Lease, Lessee may receive, collect and enjoy the rents accruing under such
sublease.  Lessor shall not, by reason of this or any other assignment of such
sublease to Lessor nor by reason of the  collection of the rents from a
sublessee, be deemed liable to the sublessee for any failure of Lessee to
perform and comply with any of Lessee's obligations to such sublessee under such
sublease.  Lessee hereby irrevocably authorizes and directs any such sublessee,
upon receipt of a written notice from Lessor stating that a default exists in
the performance of Lessee's obligations under this Lease, to pay to Lessor the
rents due and to become due under the sublease.    Lessee agrees that such
sublessee shall have the right to rely upon any such statement and request from
Lessor, and that such sublessee shall pay such rents to Lessor without any
obligation or

<PAGE>


right to inquire as to whether such default exists and notwithstanding any 
notice from or claim from Lessee to the contrary.  Lessee shall have no right 
or claim against such sublessee or Lessor for any such rents so paid by said 
sublessee to Lessor.

         (b)  No sublease entered into by Lessee shall be effective unless and
until it has been approved in writing by Lessor.  In entering into any sublease,
Lessee shall use only such form of sublease as is satisfactory to Lessor, and
once approved by Lessor, such sublease shall not be changed or modified without
Lessor's prior written consent.  Any sublessee shall, by reason of entering into
a sublease under this Lease, be deemed, for the benefit of Lessor, to have
assumed and agreed to conform and comply with each and every obligation herein
to be performed by Lessee other than such obligations as are contrary to or
inconsistent with provisions contained in a sublease to which Lessor has
expressly consented in writing.

         (c)  If Lessee's obligations under this Lease have been guaranteed by
third parties, then a sublease, and Lessor's consent thereto, shall not be
effective unless said guarantors give their written consent to such  sublease
and the terms thereof.

         (d)  The consent by Lessor to any subletting shall not release Lessee
from its obligations or alter the primary liability of Lessee to pay the rent
and perform and comply with all of the obligations of Lessee to be performed
under this Lease.

         (e)  The consent by Lessor to any subletting shall not constitute a
consent to any subsequent subletting by Lessee or to any assignment or
subletting by the sublessee.  However, Lessor may consent to subsequent
sublettings and assignments of the sublease or any amendments or modifications
thereto without notifying Lessee or anyone else liable on the Lease or sublease
and without obtaining their consent and such action shall not relieve such
persons from liability.

         (f)  In the event of any default under this Lease, Lessor may proceed
directly against Leases, any guarantors or any one else responsible for the
performance of this Lease, including the sublessee, without first exhausting
Lessor's remedies against any other person or entity responsible therefore to
Lessor, or any security held by Lessor or Lessee.

         (g)  In the event Lessee shall default in the performance of its
obligations under this Lease, Lessor, at its option and without any obligation
to do so, may require any sublessee to attorn to Lessor, in which event Lessor
shall undertake the obligations of Lessee under such sublease from the time of
the exercise of said option to the termination of such sublease; provided,
however, Lessor shall not be liable for any prepaid rents or security deposit
paid by such sublessee to Leases or for any other prior defaults of Lessee under
such sublease.

         (h)  Each and every consent required of Lessee under a sublease shall
also require the consent of Lessor.

         (i)  No sublessees shall further assign or sublet all or any part of
the Premises without Lessor's prior written consent.

         (j)  Lessor's written consent to any subletting of the Premises by
Lessee shall not constitute an acknowledgement that no default then exists under
this Lease of the obligations to be performed by Lessee nor shall such consent
be deemed a waiver of any then existing default, except as may be otherwise
stated by lessor at the time.

         (k)  With respect to any subletting to which Lessor has consented,
Lessor agrees to deliver a copy of any notice of default by Lessee to the
sublessee.  Such sublessee shall have the right to cure a default of Lessee
within ten (10) days after service of said notice of default upon such
sublessee, and the sublessee shall have a right of reimbursement and offset from
and against Lessee for any such defaults cured by the sublessee.

    12.5 Attorney's Fees.  In the event Lessee shall assign or sublet the
Premises or request the consent of Lessor to any assignment or subletting or if
Lessee shall request the consent of Lessor for any act Lessee proposes to do
then Lessee shall pay Lessor's reasonable attorney's fees incurred in connection
therewith, such attorney's fees not to exceed $350.00 for each such request.

13. Default; Remedies.

    13.1 Default.  The occurrence of any one or more of the following events
shall constitute a material default of this Lease by Lessee:

         (a)  The vacating or abandonment of the Premises by Lessee.

         (b)  The failure by Lessee to make any payment of rent or any other
payment required to be made by Lessee hereunder, as and when due, where such
failure shall continue for a period of three (3) days after written notice
thereof from Lessor to Lessee.  In the event that Lessor serves Lessee with a
Notice to Pay Rent or Quit pursuant to applicable Unlawful Detainer statutes
such Notice to Pay Rent or Quit shall also constitute the notice required by
this subparagraph.

         (c)  Except as otherwise provided in this Lease, the failure by Lessee
to observe or perform any of the covenants, conditions or provisions of this
Lease to be observed or performed by Lessee, other than described in paragraph
(b) above, where such failure shall continue for a period of thirty (30) days
after written notice thereof from lessor to Lessee; provided, however, that if
the nature of Lessee's noncompliance is such that more than thirty (30) days are
reasonably required for its cure, then Lessee shall not be deemed to be in
default if Lessee commenced such cure within said thirty (30) day period and
thereafter diligently prosecutes such cure to completion.  To the extent

<PAGE>


permitted by law, such thirty (30) day notice shall constitute the sole and
exclusive notice required to be given to Lessee under applicable Unlawful
Detainer statutes.

         (d)  (i)  The making by Lessee of any general arrangement or general
assignment for the benefit of creditors; (ii) Lessee becomes a "debtor" as
defined in 11 U.S.C. } 101 or any successor statute thereto (unless, in the case
of a petition filed against Lessee, the same is dismissed within sixty (60)
days); (iii) the appointment of a trustee or receiver to take possession of
substantially all of Lessee's assets located at the Premises or of Lessee's
interest in this Lease, where possession is not restored to Lessee within thirty
(30) days; or (iv) the attachment, execution or other judicial seizure of
substantially all of Lessee's assets located at the Premises or of Lessee's
interest in this Lease, where such seizure is not discharged within thirty (30)
days.  In the event that any provision of this paragraph 13.1(d) is contrary to
any applicable law, such provision shall be of no force or effect.

         (e)  The discovery by Lessor that any financial statement given to
Lessor by Lessee, any assignee of Lessee, any subtenant of Lessee, any successor
in interest of Lessee or any guarantor of Lessee's obligation hereunder, was
materially false.

    13.2 Remedies.  In the event of any such material default by Lessee, Lessor
may at any time thereafter, with or without notice or demand and without
limiting Lessor in the exercise of any right or remedy which Lessor may have by
reason of such default:

         (a)  Terminate Lessee's right to possession of the Premises by any
lawful means, in which case this Lease and the term hereof shall terminate and
Lessee shall immediately surrender possession of the Premises to Lessor.  In
such event Lessor shall be entitled to recover from Lessee all damages incurred
by Lessor by reason of Lessee's default including, but not limited to, the cost
of recovering possession of the Premises; expenses of  reletting, including
necessary renovation and alteration of the Premises, reasonable attorney's fees,
and any real estate commission actually paid; the worth at the time of award by
the court having jurisdiction thereof of the amount by which the unpaid rent for
the balance of the term after the time of such aware exceeds the amount of such
rental loss for the same period that Lessee proves could be reasonably avoided;
that portion of the leasing commission paid by Lessor pursuant to paragraph 15
applicable to the unexpired term of this Lease.

         (b)  Maintain Lessee's right to possession in which case this Lease
shall continue in effect whether or not Lessee shall have vacated or abandoned
the Premises.  In such event Lessor shall be entitled to enforce all of Lessor's
rights and remedies under this Lease, including the right to recover the rent as
it becomes due hereunder.

         (c)  Pursue any other remedy now or hereafter available to Lessor
under the laws or judicial decisions of the state wherein the Premises are
located.  Unpaid installments of rent and other unpaid monetary obligations of
Lessee under the terms of this Lease shall bear interest from the date due at
the maximum rate then allowable by law.

    13.3 Default by Lessor.  Lessor shall not be in default unless Lessor fails
to perform obligations required of Lessor within a reasonable time, but in no
event later than thirty (30) days after written notice by Lessee to Lessor and
to the holder of any first mortgage or deed of trust covering the Premises whose
name and address shall have theretofore been furnished to Lessee in writing,
specifying wherein Lessor has failed to perform such obligation; provided,
however, that if the nature of Lessor's obligation is such that more than thirty
(30) days are required for performance then Lessor shall not be in default if
Lessor commences performance within such thirty (30) day period and thereafter
diligently prosecutes the same to completion.

    13.4 Late Charges.  Lessee hereby acknowledges that late payment by Lessee
to Lessor of Base Rent, Lessee's Share of Operating Expenses or other sums due
hereunder will cause Lessor to incur costs not contemplated by this Lease, the
exact amount of which will be extremely difficult to ascertain.  Such costs
include, but are not limited to processing and accounting charges, and late
charges which may be imposed on Lessor  by the terms of any mortgage or trust
deed covering the Property.  Accordingly, if any installment of Base Rent,
Operating Expenses, or any other sum due from Lessee shall not be received by
Lessor or Lessor's designee within ten (10) days after such amount shall be due,
then, without any requirement for notice to Lessee, Lessee shall pay to Lessor a
late charge equal to 6% of such overdue amount.  The parties hereby agree that
such late charge represents a fair and reasonable estimate of the costs Lessor
will incur by reason of late payment by Lessee.  Acceptance of such late charge
by lessor shall in no event constitute a waiver of Lessee's default with respect
to such overdue amount, nor prevent Lessor from exercising any of the other
rights and remedies granted hereunder.  In the event that a late charge is
payable hereunder, whether or not collected, for three (3) consecutive
installments of any of the aforesaid monetary obligations of Lessee, then Base
Rent shall automatically become due and payable quarterly in advance, rather
than monthly, notwithstanding paragraph 4.1 or any other provision of this Lease
to the contrary.

    14.  Condemnation.  If the Premises or any portion thereof or the 
Industrial Center are taken under the power of eminent domain, or sold under 
the threat of the exercise of said power (all of which are herein called 
"condemnation"), this Lease shall terminate as to the part so taken as of  
the date the condemning authority takes title or possession, whichever first 
occurs. If more than ten percent of the floor area of the Premises, or more 
than twenty-five percent of that portion of the Common Areas designated as 
parking for the Industrial Center is taken by condemnation, Lessee may, at 
Lessee's option, to be exercised in writing within ten (10) days after Lessor 
shall have given Lessee written notice of such taking (or in the absence of 
such notice, within ten (10) days after the condemning authority shall have 
taken possession) terminate this Lease as of the date the condemning 
authority takes such possession.  If Lessee does not terminate this Lease in 
accordance with the foregoing, this Lease shall remain in full force and 
effect as to the portion of the premises remaining, except that the rent 
shall be reduced in the proportion that the floor area of the Premises taken 
bears to the total floor area of the Premises.  No reduction of rent shall 
occur if the only area taken is that which does not have the Premises located 
thereon.  Any award for the taking of all or any part of the Premises under 
the power of eminent domain or any payment made under threat of the exercise 
of such power shall be the property of Lessor, whether such award shall be 
made as compensation for diminution in value of the leasehold or for the 
taking of the fee, or as severance damages; provided, however, that Lessee 
shall be entitled to any

<PAGE>


award for loss of or damage to Lessee's trade fixtures and removable personal 
property.  In the event that this Lease is not terminated by reason of such 
condemnation, Lessor shall to the extent of severance damages received by 
Lessor in connection with such condemnation, repair any damage to the 
Premises caused by such condemnation except to the extent that Lessee has 
been reimbursed therefor by the condemning authority, Lessee shall pay any 
amount in excess of such severance damages required to complete such repair.

    15.  Broker's Fee.

         (a)  Upon execution of this Lease by both parties, Lessor shall pay to
SEE ADDENDUM #58

Licensed real estate broker(s), a fee as set forth in a separate agreement
between Lessor and said broker(s), or in the event there is no separate
agreement between Lessor and said broker(s), the sum of $_____ , for brokerage
services rendered by said broker(s) to Lessor in this transaction.

         (b)  Lessor further agrees that if Lessee exercises an Option, as
defined in paragraph 40.1 of this Lease, which is granted to Lessee under this
Lease, or any subsequently granted option which is substantially similar to an
Option granted to Lessee under this Lease, or if Lessee acquires any rights to
the Premises or other premises described in this Lease which are substantially
similar to what Lessee would have acquired had an Option herein granted to
Lessee been exercised, or if Lessee remains in possession of the Premises after
the expiration of the term of this Lease after having failed to exercise an
Option, or if said broker(s) are the procuring cause of any other lease or sale
entered into between the parties pertaining to the Premises and/or any adjacent
property in which Lessor has an interest, then as to any of said transactions,
Lessor shall pay said broker(s) a fee in accordance with the schedule of said
broker(s) in effect at the time of execution of this Lease.

         (c)  Lessor agrees to pay said fee not only on behalf of Lessor but
also on behalf of any person, corporation, association, or other entity having
an ownership interest in said real property or any part thereof, when such fee
is due hereunder. Any transferee of Lessor's interest in this Lease, whether
such transfer is by agreement or by operation of law, shall be deemed to have
assumed Lessor's obligation under this paragraph 15.  Said broker shall be a
third party beneficiary of the provisions of this paragraph 15.

    16.  Estoppel Certificate.

         (a)  Each party (as "responding party") shall at any time upon not
less than ten (10) days' prior written notice from the other party ("requesting
party") execute, acknowledge and deliver to the requesting party a statement in
writing (i) certifying that this Lease is unmodified and in full force and
effect (or, if modified, stating the nature of such modification and certifying
that this Lease as so modified, is in full force and effect) and the date to
which the rent and other charges are paid in advance, if any, and (ii)
acknowledging that there are not, to the responding party's knowledge, any
uncured defaults on the part of the requesting party or specifying such defaults
if any are claimed.  Any such statement may be conclusively relied upon by any
prospective purchaser r encumbrancer of the Premises or of the business of the
requesting party.

         (b)  At the requesting party's option, the failure to deliver such
statement within such time shall be a material default of this Lease by the
party who is to respond, without any further notice to such party, or it shall
be conclusive upon such party that (i) this Lease is in full force and effect,
without modification except as may be represented by the requesting party, (ii)
there are no uncured defaults in the requesting party's performance, and (iii)
if Lessor is the requesting party, not more than one month's rent has been paid
in advance.

         (c)  If Lessor desires to finance, refinance, or sell the Property, or
any part thereof, Lessee hereby agrees to deliver to any lender or purchaser
designated by Lessor such financial statements of Lessee as may be reasonably
required by such lender or purchaser.  Such statements shall include the past
three (3) years' financial statements of Lessee.  All such financial statements
shall be received by Lessor and such lender or purchaser in confidence and shall
be used only for the purposes herein set forth.

17. Lessor's Liability.  The term "Lessor" as used herein shall mean only the
owner or owners, at the time in question, of the fee title or a lessee's
interest in a ground lease of the Industrial Center, and except as expressly
provided in paragraph 15, in the event of any transfer of such title or
interest. Lessor herein named (and in case of any subsequent transfers then the
grantor) shall be relieved from and after the date of such transfer of all
liability as respects Lessor's obligations thereafter to be performed, provided
that any funds in the hands of Lessor or the then grantor at the time of such
transfer, in which Lessee has an interest, shall  be delivered to the grantee. 
The obligations contained in this Lease  to be performed by Lessor shall,
subject as aforesaid, be binding on Lessor's successors and assigns, only during
their respective periods of ownership.

18. Severability. The invalidity of any provision of this Lease as determined
by a court of competent jurisdiction, shall in no way affect the validity of any
other provision hereof.

19. Interest on Past-due Obligations.  Except as expressly herein provided, any
amount due to Lessor not paid when due shall bear interest at the maximum rate
then allowable by law from the date due.  Payment of such interest shall not
excuse or cure any default by Lessee under this Lease; provided, however, that
interest shall not be payable on late charges incurred by Lessee nor on any
amounts upon which late charges are paid by Lessee.

20. Time of Essence.  Time is of the essence with respect to the obligations to
be performed under this Lease.

21. Additional Rent. All monetary obligations of Lessee to Lessor under the
terms of this Lease, including but not limited to Lessee's Share of Operating
Expenses and insurance and tax expenses payable shall be deemed to be rent.

22. Incorporation of Prior Agreements; Amendments.  This Lease contains all
agreements of the parties with respect to any matter mentioned herein.  No prior
or contemporaneous agreement or understanding pertaining to any

<PAGE>


such matter shall be effective.  This lease may be modified in writing only, 
signed by the parties in  interest at the time of the modification.  Except 
as otherwise stated in this Lease, Lessee hereby acknowledges that neither 
the real estate broker listed in paragraph 15 hereof nor any cooperating 
broker on this transaction nor the Lessor or any employee or agents of any of 
said persons has made an oral or written warranties or representations to 
Lessee relative to the condition or use by Lessee of the Premises or the 
Property and Lessee acknowledges that Lessee assumes all responsibility 
regarding the Occupational Safety Health Act, the legal use and adaptability 
of the Premises and the compliance thereof with all  applicable laws and 
regulations in effect during the  term of this Lease except as otherwise 
specifically stated in this Lease.

23. Notices.  Any notice required or permitted to be given hereunder shall be
in writing and may be given by personal delivery or by certified mail, and if
given personally or by mail, shall be deemed sufficiently given if addressed to
Lessee or to Lessor at the address noted below the signature of the respective
parties, as the case may be.  Either party may by notice to the other specify a
different address for notice purposes except that upon Lessee's taking
possession of the Premises, the Premises shall constitute Lessee's address for
notice purposes.  A copy of all notices required or permitted to be given to
Lessor hereunder shall be concurrently transmitted to such party or parties at
such addresses as Lessor may from time to time hereafter designate by note to
Lessee.

24. Waivers.  No waiver by Lessor or any provision hereof shall be deemed a 
waiver of any another provision hereof or of any subsequent breach by Lessee 
of the same or any other provision.  Lessor's consent to, or approval of, any 
act shall not be deemed to render unnecessary the obtaining of Lessor's 
consent to or approval of any subsequent act by lessee.  The acceptance of 
rent hereunder by Lessor shall not be a waiver of any preceding breach by 
Lessee of any provision hereof, other than the failure of Lessee to pay the 
particular rent so accepted, regardless of Lessor's knowledge of such 
preceding breach at the time of acceptance of such rent.

25. Recording.  Either Lessor or Lessee shall, upon request of the other,
execute, acknowledge and deliver to the other a "short form" memorandum of this
Lease for recording purposes.

26. Holding Over.  If Lessee, with Lessor's consent, remains in possession of
the Premises or any part thereof after the expiration of the term hereof, such
occupancy shall be a tenancy from month to month upon all the provisions of this
Lease pertaining to the obligations of Lessee, but all Options, if any , granted
under the terms of this Lease shall be deemed terminated and be of no further
effect during said month to month tenancy.

27. Cumulative Remedies.  No remedy or election hereunder shall be deemed
exclusive but shall, wherever possible, be cumulative with all other remedies at
law or in equity.

28. Covenants and Conditions.  Each provision of this Lease performable by
Lessee shall be deemed both a covenant and a condition.

29. Binding Effect; Choice of Law.  Subject to any provisions hereof
restricting assignment or subletting by Lessee and subject to the provisions of
paragraph 17, this Lease shall bind the parties, their personal representatives,
successors and assigns.  This Lease shall be governed  by the laws of the State
where the Industrial Center is located and any litigation concerning this Lease
between the parties hereto shall be initiated in the county in which the
Industrial Center is located.

30. Subordination.  See addendum #62.

    (a)  This Lease, and any Option granted hereby, at Lessor's option, shall
be subordinate to any ground lease, mortgage, deed of trust, or any other
hypothecation or security now or hereafter placed upon the Industrial Center and
to any and all advances made on the security thereof and to all renewals,
modifications, consolidations, replacements and extensions thereof.  
Notwithstanding such subordination, Lessee's right to quiet possession of the
Premises shall not be disturbed if Lessee is not in default and so long as
Lessee shall pay the rent and observe and perform all of the provisions of this
Lease is otherwise terminated pursuant to its terms.  If any mortgagee, trustee
or ground lessor shall elect to have the Lease and any Options granted hereby
prior to the lien of its mortgage, deed of trust or ground lease, and shall give
written notice thereof to Lessee, this Lease and such Options shall be deemed
prior to such mortgage, deed of trust or ground lease, whether this Lease or
such Options are dated prior or subsequent to the date of said mortgage, deed of
trust or ground lease or the date of recording thereof.

    (b)  Lessee agrees to execute any documents required to effectuate an
attornment, a subordination or to make this Lease or any Option granted herein
prior to the lien of any mortgage, deed of trust or ground lease, as the case
may be.  Lessee's failure to execute such documents within ten (10) days after
written demand shall constitute a material default by Lessee hereunder without
further notice to Lessee or, at Lessor's option, Lessor shall execute such
documents on behalf of Lessee as Lessee's attorney-in-fact.  Lessee does hereby
make, constitute and irrevocably appoint Lessor as Lessee's attorney-in-fact and
in Lessee's name, place and stead, to execute such documents in accordance with
this paragraph 30(b).

31. Attorney's Fees.  If either party or the broker(s) named herein bring an 
action to enforce the terms hereof or declare rights hereunder, the 
prevailing party in any such action, on trial or appeal, shall be entitled to 
his reasonable attorney's fees to be paid by the losing party as fixed by the 
court. The provisions of this paragraph shall inure to the benefit of the 
broker named herein who seeks to enforce a right hereunder.

32. Lessor's Access.  Lessor and Lessor's agents shall have the right to enter
the Premises at reasonable times for the purpose of inspecting the same, showing
the same to prospective purchasers, lenders, or lessees, and making such
alterations, repairs, improvements or additions to the Premises or to the
building of which they are part as Lessor may deem necessary or desirable. 
Lessor may at any time place on or about the Premises or the Building any
ordinary "For Sale" signs and Lessor may at any time during the last 120 days of
the term hereof place on or about the Premises any ordinary "For Lease" signs. 
All activities of Lessor pursuant to this paragraph shall be without abatement
of rent, nor shall Lessor have any liability to Lessee for the same.

<PAGE>


33. Auctions.  Lessee shall not conduct, nor permit to be conducted, either
voluntarily or involuntarily, any auction upon the Premises or the Common Areas
without first having obtained Lessor's prior written consent.  Notwithstanding
anything to the contrary in this Lease, Lessor shall not be obligated  to
exercise any standard of reasonableness in determining whether to grant such
consent.

34. Signs.  Lessee shall not place any sign upon the Premises or the Industrial
Center without Lessor's prior written consent.  Under no  circumstances shall
Lessee place a sign on any roof of the Industrial Center.

35. Merger.  The voluntary or other surrender of this Lease by Lessee, or a 
mutual cancellation thereof,  or a termination by Lessor, shall not work a 
merger, and shall, at the option of Lessor, terminate all or any existing 
subtenancies or may, at the option of Lessor, operate as an assignment to 
Lessor of any or all of such subtenancies.

36. Consents.  Except for paragraph 33 hereof, wherever in this Lease the 
consent of one party is required to an act of the other party such consent 
shall not be unreasonably withheld or delayed.

37. Guarantor.  In the event that there is a guarantor of this Lease, said
guarantor shall have the same obligations as Lessee under this Lease.

38. Quiet Possession.  Upon Lessee paying the rent for the Premises and
observing and performing all of the covenants, conditions and provisions on
Lessee's part to be observed and performed hereunder, Lessee shall have quiet
possession of the Premises for the entire term hereof subject to all of the
provisions of this Lease.  The individuals executing this Lease on behalf of
Lessor represent and warrant to Lessee that they are fully authorized and
legally capable of executing this Lease on behalf of Lessor and that such
execution is binding upon all parties holding an ownership interest in the
Property.

39. Options.

    39.1 Definition.  As used in this paragraph the word "Option" has the
following meaning:  (1) the right or option to extend the term of this Lease or
to renew this Lease to extend or renew any lease that Lessee has on other
property of Lessor; (2) the option or right of first refusal to lease the
Premises or the right of first offer to lease the Premises or the right of first
refusal to lease other space within the Industrial Center or other property of
Lessor or the right of first offer to lease other space within the Industrial
Center or other property of Lessor; (3) the right or option to purchase the
Premises or the Industrial Center, or the right of first refusal to purchase the
Premises or the Industrial Center, or the right of first offer to purchase the
Premises or the Industrial Center, or the right or option to  purchase other
property of Lessor, or the right of first refusal to purchase other property of
Lessor or the right of first offer to purchase other property of Lessor.

    39.2 Options Personal.  Each Option granted to Lessee in this Lease is
personal to the original Lessee and may be exercised only by the original Lessee
while occupying the Premises who does so without the intent of thereafter
assigning this Lease or subletting the Premises or any portion thereof, and may
not be exercised or be assigned, voluntarily, or involuntarily, by or to any
person or entity other than Lessee, provided, however, that an Option may be
exercised by or assigned to any Lessee Affiliate as defined in paragraph 12.2 of
this Lease.  The Options, if any, herein granted to Lessee are not assignable
separate and apart from this Lease, nor may any Option be separated from this
Lease in any manner, either by reservation or otherwise.

    39.3 Multiple Options.  In the event that Lessee has any multiple options
to extend or renew this Lease a later option cannot be exercised unless the
prior option to extend or renew this Lease has been so exercised.

    39.4 Effect of Default on Options.

         (a)  Lessee shall have no right to exercise an Option, notwithstanding
any provision in the grant of Option to the contrary, (i) during the time
commencing from the date Lessor gives to Lessee a notice of default pursuant to
paragraph 13.1(b) or 13.1(c) and continuing until the noncompliance alleged in
said notice of default is cured, or (ii) during the period of time commencing on
the date after a monetary obligation to Lessor is due from Lessee and unpaid
(without any necessity for notice thereof to Lessee) and continuing until the
obligation is paid, or (iii) at any time after an event of default described in
paragraphs 13.1(a), 13.1(d), or 13.1(e) (without any necessity of Lessor to give
notice of such default to Lessee), or (iv) in the event that Lessor has given to
Lessee three or more notices of default under paragraph 13.1(b), or paragraph
13.1(c), whether or not the defaults are cured, during the 12 month period of
time immediately prior to the time that Lessee attempts to exercise the subject
Option.

         (b)  The period of time within which an Option may be exercised shall
not be extended or enlarged by reason of Lessee's inability to exercise an
Option because of the provisions of paragraph 39.4(a).

         (c)  All rights of Lessee under the provisions of an Option shall
terminate and be of no further force or effect, notwithstanding Lessee's due and
timely exercise of the Option, if, after such exercise and during the term of
this Lease, (i) Lessee fails to pay to Lessor a monetary obligation of Lessee
for period of thirty (30) days after such obligation becomes due (without any
necessity of Lessor to give notice thereof to Lessee), or (ii) Lessee fails to
commence to cure a default specified in paragraph 13.1(c) within thirty (30)
days after the date that Lessor gives notice to Lessee of such default and/or
Lessee fails thereafter to diligently prosecute said cure to completion, or
(iii) Lessee commits a default described in paragraphs 13.1(a), 13.1(d) or
13.1(e) (without any necessity of Lessor to give notice of such default to
Lessee), or (iv) Lessor gives to Lessee three or more notices of default under
paragraph 13.1(b), or paragraph 13.1(c), whether or not the defaults are cured.

40. Security Measures.  Lessee hereby acknowledges that Lessor shall have no
obligation whatsoever to provide guard service or other security measures for
the benefit of the Premises or the Industrial Center.  Lessee assumes all
responsibility for the protection of Lessee, its agents, and invitees and the
property of Lessee and of Lessee's agents

<PAGE>


and invitees from acts of third parties.  Nothing herein contained shall 
prevent Lessor, at Lessor's sole option, from providing security protection 
for the Industrial Center or any part thereof, in which event the cost 
thereof shall be included within the definition of Operating Expenses, as set 
forth in paragraph 4.2(b)

41. Easements.  Lessor reserves to itself the right, from time to time, to
grant such easements, rights and dedications that Lessor deems necessary or
desirable, and to cause the recordation of Parcel Maps and restrictions, so long
as such easements, rights, dedications, Maps and restrictions do not
unreasonably interfere with the use of the Premises by Lessee.  Lessee shall
sign any of the aforementioned documents upon request of Lessor and failure to
do so shall constitute a material default of this Lease by Lessee without the
need for further notice to Lessee.

42. Performance Under Protest.  If at any time a dispute shall arise as to any
amount or sum of money to be paid by one party to the other under the provisions
hereof, the party against whom the obligation to pay the money is asserted shall
have the right to make payment "under protest" and such payment shall not be
regarded as a voluntary payment, and there shall survive the right on the part
of said party to institute suit for recovery of such sum.  If it shall be
adjudged that there was no legal  obligation on the part of said party to pay
such sum or any part thereof, said party shall be entitled to recover such sum
or so much thereof as it was not legally required to pay under the provisions of
this Lease.

43. Authority.  If Lessee is a corporation, trust or general or limited
partnership, each individual executing this Lease on behalf of such entity
represents and warrants that he or she is duly authorized to execute and deliver
this Lease on behalf of said entity.  If Lessee is a corporation, trust or
partnership, Lessee shall, within thirty (30) days after execution of this
Lease, deliver to Lessor evidence of such authority satisfactory to Lessor.

44. Conflict.  Any conflict between the printed provisions of this Lease and
the typewritten or handwritten provisions, if any, shall be controlled by the
typewritten or handwritten provisions.

45. Offer. Preparation of this Lease by Lessor or Lessor's agent and submission
of same to Lessee shall not be deemed an offer to lease. This Lease shall become
binding upon Lessor and Lessee only when fully executive by Lessor and Lessee.

46. Addendum.  Attached hereto is an addendum or addenda containing paragraphs
49 through 63 which constitute a part of this Lease.

    A.   Lessor shall provide Lessee $3.00 per square foot for retrofit tenant
         improvements to the Premises. Any unused portion of this $3.00 per 
         square foot allowance may be utilized by Overland Data as a moving 
         allowance. Lessor understands that it is Lessor's responsibility to 
         have this facility comply with the American's with Disabilities Act 
         and/or any other Federal, State or Local building codes or regulations.
         All tenant improvements shall be mutually agreed upon by Lessee and 
         Lessor and constructed by a licensed general contractor. In addition,
         Lessor shall also provide Lessee up to $30,000.00 for the installation
         of an elevator to the Premises. It shall be understood by Lessor and 
         Lessee that Lessee will be responsible for the actual construction of 
         any and all tenant improvements to said Premises with Lessor's 
         approval. Lessee shall determine the State of California licensed 
         general contractor who will perform the tenant improvement construction
         work to the Premises.
    
    B.   LESSOR REPAIRS AND IMPROVEMENTS. It is mutually understood and agreed 
         that the second floor of the Premises needs repair and shall be 
         repaired at the sole expense of Lessor without regard to Lessee's 
         tenant improvement allowance. The repairs shall be made in such a 
         manner that the second floor is to be completely level and shall meet 
         the standard office load-bearing capacity to the mutual satisfaction of
         Lessee and Lessor. If for some reason the repair of the flooring causes
         non-repairable damage to the existing carpeting, then Lessor at 
         Lessor's cost will replace the carpeting. Lessor will make every effort
         to have the second floor repairs completed by July 15, 1993 in order 
         for commencement of said Lease to occur August 15, 1993. Should their 
         be any delays beyond July 15, 1993 and the repair of the second floor, 
         then said lease commencement date shall extend from August 15, 1993 
         commensurate with the delays associated with repairing the second 
         floor. The extension of the lease commencement date pursuant to 
         Section 54b shall be in addition to any extension required due to 
         delays by Lessor in approving Lessee's tenant improvement plans for 
         said facility.

         It is also understood that should the City of San Diego require any 
         changes to any of the existing improvements due to building code 
         issues, then Lessor shall be responsible for any and all costs 
         associated therewith. Should any building code requirements be 
         implemented by the City of San Diego relating to the existing tenant 
         improvements due to Lessee's addition of improvements, then Lessee 
         shall be responsible for all costs associated therewith.

    writing of its intent to exercise its right of first refusal to occupy the 
    Premises under the same terms and conditions as contained in the mutually

    shall not be deemed to have terminated any other right of first refusal on

    Notwithstanding the foregoing, all other lease terms and conditions shall be
    in effect for the space.

56. RENEWAL OPTIONS: Lessor hereby grants Lessee two (2) options to renew of
    five (5) years each at ninety percent (90%) of the then prevailing market

    the Lessee and the Lessor. Should Lessee and Lessor be unable to agree upon 
    a rental rate, then an MAI appraiser shall be utilized to determine the 
    rental rate. These options shall be exercised by written notice delivered to
    the Lessor eight (8) months prior to lease expiration. If Lessee and Lessor 
    fail to reach an agreement within ninety (90) days of written notification 
    to Lessor, then this option shall lapse and there shall be no further right 
    to extend the lease term.

57. Signage: Project signage similar to what Sundstrand currently has at the

    sign ordinances.

         Lessee. However, no later than one-half on August 15, 1993 and the

         August 15, 1993.

    assignment shall be deeded to have occurred upon any sale or other transfer

    all cases to the provisions of Section 6, to any assignment or subletting by
    Lessee to an affiliated entity which: a) is Lessee's parent organization; b)

    wholly destroyed or damaged by fire or other casualty in such damage or
    destruction cannot in Lessor's architect's judgement, be repaired or

    hold Lessee harmless from and against any and all loss, costs, liability, or
    expense, including reasonable attorneys and consultants fees, arising out of
    the presence, removal, clean-up, spill, release, discharge or use of any

    replacements and extensions thereof. Lessee shall, upon written demand by

may grant Options under the Plan to such persons and may determine the timing,
number of Shares subject to such Options and other terms of such grants.

    (b)  DISINTERESTED DIRECTORS. A member of the Board of Directors shall be
deemed "disinterested" only if he or she satisfies such requirements as the
Securities and Exchange Commission may establish for disinterested
administrators of plans designed to qualify for exemption under Rule 16b-3 (or
its successor) under the Exchange Act.

    (c)  COMMITTEE PROCEDURES.  The Committee shall designate one of its
members as chairman. The Committee may hold meetings at such times and places
as it shall determine. The acts of a majority of the Committee members present
at meetings at which a quorum exists, or acts reduced to or approved in writing
by all Committee members, shall be valid acts of the Committee.

                                       3

    (d)  COMMITTEE RESPONSIBILITIES.  Subject to the provisions of the Plan,
and without further approval of the Board of Directors, the Committee shall have
full authority and discretion to take the following actions:

         (i)    To interpret the Plan and to apply its provisions;

         (ii)   To adopt, amend or rescind rules, procedures and forms relating
to the Plan;

         (iii)  To authorize any person to execute, on behalf of the
Company, any instrument required to carry out the purposes of the Plan;

         (iv)   To determine when Options are to be granted under the Plan;

         (v)    To select the Optionees;

         (vi)   To determine the number of Shares to be made subject to each
Option;

         (vii)  To prescribe the terms and conditions of each Option,
including, without limitation, the Exercise Price, to determine whether such
Option is to be classified as an ISO or as a Nonstatutory Option, and to specify
the provisions of the Stock Option Agreement relating to such Option;

         (viii) To amend any outstanding Stock Option Agreement, subject to
applicable legal restrictions and to the consent of the Optionee who entered
into such agreement;

         (ix)   To accelerate or defer, with the consent of the Optionee, the
exercise date of any Option;

         (x)    With the consent of the Optionee, to reprice, cancel and 
regrant, or otherwise adjust the Exercise Price of an option previously granted
by the Committee;

         (xi)   To prescribe the consideration for the grant of each Option or
other right under the Plan and to determine the sufficiency of such
consideration; and

         (xii)  To take any other actions deemed necessary or advisable for
the administration of the Plan.

All decisions, interpretations and other actions of the Committee shall be final
and binding on all Optionees, and all persons deriving their rights from an

she has taken or has failed to take in good faith with respect to the Plan, any
Option, or any other right to acquire Shares under the Plan.

                                       4

SECTION 4.  ELIGIBILITY.

    (a)  GENERAL RULE.  Employees and Consultants shall be eligible to receive
Options. However, only Employees shall be eligible for the grant of ISOs.

    (b)  DISINTERESTED DIRECTORS.  Disinterested Directors shall not be
eligible to receive Options under this Plan.

    (c)  TEN-PERCENT STOCKHOLDERS.  An Employee who owns more than 10 percent
of the total combined voting power of all classes of outstanding stock of the
Company or any of its Subsidiaries shall not be eligible for the grant of an
option unless (i) the Exercise Price is at least 110 percent of the Fair Market
Value of the shares underlying the Option on the date of grant of the Option and
(ii) if such Option is an ISO, such ISO is not exercisable after the expiration
of five years from the date of grant.

    (d)  ATTRIBUTION RULES.  For purposes of Subsection (c) above, in
determining stock ownership, an Employee shall be deemed to own the stock owned,
directly or indirectly, by or for such Employee's brothers, sisters, spouse,
ancestors and lineal descendants. Stock owned, directly or indirectly, by or
for a corporation, partnership, estate or trust shall be deemed to be owned
proportionately by or for its stockholders, partners or beneficiaries.  Stock
with respect to which such Employee holds an option shall be counted.

    (e)  OUTSTANDING STOCK.  For purposes of Subsection (c) above, "outstanding
stock" shall include all stock actually issued and outstanding immediately after
the grant. "Outstanding stock" shall not include shares authorized for issuance
under outstanding options held by the Employee or by any other person.

SECTION 5.  STOCK SUBJECT TO PLAN.

    (a)  BASIC LIMITATION.  Shares subject to Options granted under the Plan
shall be authorized but unissued Shares. The aggregate number of shares which
may be issued under the Plan (upon exercise of Options or other rights to
acquire Shares) shall not exceed 372,500 Shares, subject to adjustment pursuant
to Section 8. The number of Shares which are subject to Options or other rights
outstanding at any time under the Plan shall not exceed the number of Shares
which then remain available for issuance under the Plan. The Company, during
the term of the Plan, shall at all times reserve and keep available sufficient
Shares to satisfy the requirements of the Plan.

    (b)  ADDITIONAL SHARES.  In the event that any outstanding Option or other
right for any reason expires or is canceled or otherwise terminated, the Shares
allocable to the unexercised portion of such Option or other right shall again
be available for the purpose of the Plan.

SECTION 6.  TERMS AND CONDITIONS OF OPTIONS.

    (a)  STOCK OPTION AGREEMENT.  Each grant of an Option under the Plan shall
be evidenced by a Stock Option Agreement between the Optionee and the Company. 
Such Option shall be subject to all applicable terms and conditions of the Plan
and may be subject to any other terms and conditions which are not inconsistent
with the Plan and which the Committee 

                                       5

<PAGE>

deems appropriate for inclusion in a Stock Option Agreement. The provisions of 
the various Stock Option Agreements entered into under the Plan need not be 
identical.

    (b)  NUMBER OF SHARES.  Each Stock Option Agreement shall specify the
number of Shares that are subject to the Option and shall provide for the
adjustment of such number in accordance with Section 8. The Stock Option
Agreement shall also specify whether the Option is an ISO or a Nonstatutory
Option.

    (c)  EXERCISE PRICE.  Each Stock Option Agreement shall specify the
Exercise Price. The Exercise Price of an ISO shall not be less than 100 percent
of the Fair Market Value of a Share on the date of grant of the Option, except
as otherwise provided in Section 4(c). The Exercise Price of a Nonstatutory
Option shall not be less than 85 percent of the Fair Market Value of a Share on
the date of grant. Subject to the preceding two sentences, the Exercise Price
under any Option shall be determined by the Committee at its sole discretion. 
The Exercise Price shall be payable in a form described in Section 7.

    (d)  WITHHOLDING TAXES.  The Company's obligation to deliver Shares or cash
upon the exercise of Options shall be subject to the satisfaction of all
applicable Federal, State and local income tax and employment tax withholding
requirements.

       1.  The Committee may, in its discretion and in accordance with the
provisions of this Section 6(d) and such supplemental rules as the Committee may
from time to time adopt, provide any or all Optionees holding Nonstatutory
Options with the right to use Shares in satisfaction of all or part of the
Federal, State and local income tax and employment tax liabilities incurred by
such Optionees in connection with the exercise of their Options (the "Taxes"). 
The Optionee holding a Nonstatutory Option may be provided with the election to
have the Company withhold, from the Shares otherwise issuable upon the exercise
of such Nonstatutory Option, a portion of such Shares with an aggregate Fair
Market Value equal to the designated percentage (up to 100% as specified by the
Optionee) of the applicable Taxes. Any such withholding election shall be
subject to the following terms and conditions:

         (i)   The election must be made on or before the date the amount of the
Taxes incurred by the Optionee in connection with the exercise of the Option is
determined (the "Tax Determination Date").

         (ii)  The election shall be irrevocable.

         (iii) The election shall be subject to the approval of the Committee 
and none of the Shares for which the Option is exercised shall be withheld in 
satisfaction of the Taxes incurred by the Optionee in connection with such 
exercise, except to the extent the election is approved by the Committee.

         (iv)  The Shares withheld pursuant to the election shall be valued at
Fair Market Value on the Tax Determination Date.

         (v)   In no event may the number of Shares requested to be withheld
exceed in value the dollar amount of Taxes incurred by the Optionee in
connection with the exercise of the Non-statutory Option.

                                       6

<PAGE>

         (vi)  If the withholding election is to be made by an Optionee who is
at the time an officer or director of the Company subject to the short-swing
profit restrictions of Section 16(b) of the Exchange Act, then the following
limitations, in addition to the preceding provisions of this Section 6(d), shall
also be applicable:

              (A)  The election shall not become effective at any time prior to
the expiration of the six month period measured from the LATER of the grant date
of the Non-statutory Option to which such election pertains or the actual grant
date of the withholding election, and no Shares shall accordingly be withheld in
connection with any Tax Determination Date which occurs before the expiration of
such six month period.

              (B)  The election must be effected in accordance with either of
the following guidelines:  (1)  the election must be made six months or more
prior to the Tax Determination Date, and (2) the exercise of such election and
the exercise of the Non-statutory Option to which such election relates must
occur concurrently within a quarterly "window" period. Quarterly window periods
shall begin on the third business day following the date of public release of
each quarterly or annual summary statement of the Company's sales and earning
and end on the EARLIER of the 12th business day following such release date or
the Tax Determination Date.

              (C)  The six-month period specified in clauses (A) and (B) shall
not be applicable in the event of the Optionee's death or disability.

         2.   The Committee may also in its discretion and applying relevant
law in accordance with the provisions of this Section 6(d) and such supplemental
rules as the Committee may from time to time adopt, require as a condition of
delivery of the Shares upon exercise of Options, that the Optionee remit to the
Company an amount in cash or check sufficient to satisfy the Company's and the
Optionee's Taxes.

    (e)  EXERCISABILITY AND TERM.  Each Stock Option Agreement shall specify
the date when all or any installment of the Option is to become exercisable. 
The vesting of any Option shall be determined by the Committee in its sole
discretion, provided, however, the Optionee's right to exercise the Option shall
be at the rate of at least 20% per year over five years from the date the Option
is granted. A Stock Option Agreement may provide for accelerated exercisability
in the event of the Optionee's death, Total and Permanent Disability or
retirement or other events determined from time-to-time by the Committee. The
Stock Option Agreement shall also specify the term of the Option. The term
shall not exceed ten years from the date of grant, except as otherwise provided
in Section 4(c). Subject to the preceding sentence, the Committee at its sole
discretion shall determine when an Option is to expire. An Option shall be
deemed exercised when the Company receives from the Optionee (i) an executed
Stock Purchase Agreement in accordance with the terms of the Option by the
person entitled to exercise the Option and (ii) full payment for the Shares with
respect to which the Option is exercised. Full payment may, as authorized by
the Committee, consist of any consideration and method of payment allowable
under Section 7 of this Plan. Until the issuance (as evidenced by the
appropriate entry on the books of the Company or of a duly authorized transfer
agent of the Company) of the stock certificate evidencing such Shares, no right
to vote or receive dividends or any other rights as a shareholder shall exist
with respect to the Shares, notwithstanding the exercise of the Option.  No
adjustment will be made for a dividend or other right for which the record date
is prior to the date the stock certificate is issued, except as provided in
Section 8 of this Plan.  With respect to any ISOs granted under 

                                       7

<PAGE>

this Plan, the aggregate Fair Market Value (determined as of the respective date
or dates of grant) of the Shares for which one or more Options granted to any 
Employee under this Plan (or any other option plan of the Company or its parent 
or subsidiary corporations) may for the first time become exercisable as ISOs 
during any one calendar year shall not exceed the sum of One Hundred Thousand 
Dollars ($100,000). To the extent the Employee holds two or more such Options 
which become exercisable for the first time in the same calendar year, the 
foregoing limitation on the exercisability thereof as ISOs shall be applied on 
the basis of the order in which such Options are granted. To the extent such 
dollar limitation is exceeded in any one calendar year the Option shall 
nevertheless be exercisable for the excess number of Shares as a Non-statutory 
Option.

    (f)  NONTRANSFERABILITY.  During an Optionee's lifetime, such Optionee's
Option(s) shall be exercisable only by him or her and shall not be transferable.
In the event of an Optionee's death, such Optionee's Option(s) shall not be
transferable other than by will or by the laws of descent and distribution.

    (g)  TERMINATION OF SERVICE (EXCEPT BY DEATH).  If an Optionee's Service
terminates for any reason other than the Optionee's death, then such Optionee's
Option(s) shall expire on the earliest of the following occasions:

         (i)   The expiration date determined pursuant to Subsection (e) above;

         (ii)  The date thirty (30) days after the termination of the Optionee's
Service for any reason other than Total and Permanent Disability; or

         (iii) The date six (6) months after the termination of the Optionee's 
Service by reason of Total and Permanent Disability.

         The Optionee may exercise all or part of his or her Option(s) at any
time before the expiration of such Option(s) under the preceding sentence, but
only to the extent that such Option(s) had become exercisable before the
Optionee's Service terminated or became exercisable as a result of the
termination. The balance of such Option(s) shall lapse when the Optionee's
Service terminates. In the event that the Optionee dies after the termination
of the Optionee's Service but before the expiration of the Optionee's Option(s),
all or part of such Option(s) may be exercised (prior to expiration) by the
executors or administrators of the Optionee's estate or by any person who has
acquired such Option(s) directly from the Optionee by bequest or inheritance,
but only to the extent that such Option(s) had become exercisable before the
Optionee's Service terminated or became exercisable as a result of the
termination. For purposes of the foregoing provisions of this Section 6(g), the
Optionee shall be deemed to be providing Service to the Company for so long as
the Optionee renders Service on a periodic basis to the Company or a Subsidiary
in the capacity of an Employee or Consultant. The Optionee shall be considered
to be an Employee for so long as the Optionee remains in the employ of the
Company or a Subsidiary.

    (h)  LEAVES OF ABSENCE.  For purposes of Subsection (g) above, Service
shall be deemed to continue while the Optionee is on military leave, sick leave
or other bona fide leave of absence (as determined by the Committee). The
foregoing notwithstanding, in the case of an ISO granted under the Plan, Service
shall not be deemed to continue beyond the first 90 days of such leave, unless
the Optionee's reemployment rights are guaranteed by statute or by contract.

                                       8

<PAGE>

    (i)  DEATH OF OPTIONEE.  If an Optionee dies while he or she is providing
Service to the Company, then such Optionee's Option(s) shall expire on the
earlier of the following dates:

         (i)  The expiration date determined pursuant to Subsection (e) above;
or

         (ii) The date six (6) months after the Optionee's death.

All or part of the Optionee's Option(s) may be exercised at any time before the
expiration of such Option(s) under the preceding sentence by the executors or
administrators of the Optionee's estate or by any person who has acquired such
Option(s) directly from the Optionee by bequest or inheritance, but only to the
extent that such Option(s) had become exercisable before the Optionee's death or
became exercisable as a result of the Optionee's death. The balance of such
Option(s) shall lapse when the Optionee dies.

    (j)  NO RIGHTS AS A STOCKHOLDER.  An Optionee, or a transferee of an
Optionee, shall have no rights as a stockholder with respect to any Shares
covered by his or her Option until the date of the issuance of a stock
certificate for such Shares. No adjustments shall be made, except as provided
in Section 8.

    (k)  MODIFICATION, EXTENSION AND RENEWAL OF OPTIONS.  Within the
limitations of the Plan, the Committee may modify, extend or renew outstanding
Options or may accept the cancellation of outstanding Options (to the extent not
previously exercised) in return for the grant of new Options at the same or a
different price. The foregoing notwithstanding, no modification of an Option
shall, without the consent of the Optionee, impair such Optionee's rights or
increase his or her obligations under such Option.

    (l)  RESTRICTIONS ON TRANSFER OF SHARES.  Any Shares issued upon exercise
of an Option shall be subject to such transfer restrictions as the Committee
shall determine so long as such restrictions do not unfairly prejudice the
opportunity of the Optionee to receive the fair value of the securities as
required under Rule 260.140.8, Title 10 of the California Code of Regulations,
in addition to any general restrictions that may apply to all holders of shares.


         (i) Options may not be transferred or assigned in any manner other than
by will or by the laws of descent or distribution.

    (m)  RULE 16b-3.  Options granted to persons who are subject to Section 16
of the Exchange Act must comply with the applicable provisions of Rule 16b-3
promulgated therein and shall contain such additional conditions or restrictions
as may be required thereunder to qualify for the maximum exemption from
Section 16 of the Exchange Act with respect to Plan transactions, provided,
however, that this provision shall not apply if at the time of such option grant
the Plan, as it relates to such grant, is not administered by a Committee
consisting solely of Disinterested Directors.  

SECTION 7.  PAYMENT FOR SHARES.

    (a)  GENERAL RULE.  The entire Exercise Price of Shares issued under the
Plan shall be payable in lawful money of the United States of America at the
time when such Shares are purchased, except as follows:

                                       9

<PAGE>

         (i)  In the case of an ISO granted under the Plan, payment shall be
made only pursuant to the express provisions of the applicable Stock Option
Agreement. However, the Committee (at its sole discretion) may specify in the
Stock Option Agreement that payment may be made pursuant to Subsections (b), (c)
or (d) below.

         (ii) In the case of a Nonstatutory Option granted under the Plan, the
Committee (at its sole discretion) may accept payment pursuant to
Subsections (b), (c) or (d) below.

    (b)  SURRENDER OF STOCK.  To the extent that this Subsection (b) is
applicable, payment may be made all or in part with Shares which have already
been owned by the Optionee or his or her representative for more than 12 months
and which are surrendered to the Company in good form for transfer. Such Shares
shall be valued at their Fair Market Value on the date when the new Shares are
purchased under the Plan.

    (c)  EXERCISE/SALE.  To the extent that this Subsection (c) is applicable,
payment may be made by the delivery (on a form prescribed by the Company) of an
irrevocable direction to a securities broker approved by the Company to sell
Shares and to deliver all or part of the sales proceeds to the Company in
payment of all or part of the Exercise Price and any withholding taxes.

    (d)  EXERCISE/PLEDGE.  To the extent that this Subsection (d) is
applicable, payment may be made by the delivery (on a form prescribed by the
Company) of an irrevocable direction to pledge Shares to a securities broker or
lender approved by the Company, as security for a loan, and to deliver all or
part of the loan proceeds to the Company in payment of all or part of the
Exercise Price and any withholding taxes.

SECTION 8.  ADJUSTMENT OF SHARES.

    (a)  GENERAL.  In the event of a subdivision of the outstanding Stock, a
declaration of a dividend payable in Shares, a declaration of a dividend payable
in a form other than Stock in an amount that has a material effect on the value
of Stock, a combination or consolidation of the outstanding Stock (by
reclassification or otherwise) into a lesser number of Shares, a
recapitalization, a spinoff or a similar occurrence, the Committee shall make
appropriate adjustments in one or more of (i) the number of Shares available for
future grants under Section 5, (ii) the number of Shares covered by each
outstanding Option or (iv) the Exercise Price under each outstanding Option.

    (b)  RESERVATION OF RIGHTS.  Except as provided in this Section 8, an
Optionee shall have no rights by reason of any subdivision or consolidation of
shares of stock of any class, the payment of any dividend or any other increase
or decrease in the number of shares of stock of any class. Any issue by the
Company of shares of stock of any class, or securities convertible into shares
of stock of any class, shall not affect, and no adjustment by reason thereof
shall be made with respect to, the number or Exercise Price of Shares subject to
an Option. The grant of an Option pursuant to the Plan shall not affect in any
way the right or power of the Company to make adjustments, reclassification,
reorganizations or changes of its capital or business structure, to merge or
consolidate or to dissolve, liquidate, sell or transfer all or any part of its
business or assets.

                                      10

<PAGE>

SECTION 9.  SECURITIES LAWS.

    Shares shall not be issued under the Plan unless the issuance and delivery
of such Shares complies with (or is exempt from) all applicable requirements of
law, including (without limitation) the Securities Act of 1933, as amended, the
rules and regulations promulgated thereunder, state securities laws and
regulations, and the regulations of any stock exchange on which the Company's
securities may then be listed.

SECTION 10.  NO EMPLOYMENT RIGHTS.

    No provision of the Plan, nor any right or Option granted under the Plan,
shall be construed to give any person any right to become, to be treated as, or
to remain an Employee or Consultant or in any way to amend, modify, waive or
terminate the Company's (or its Subsidiary's) right to terminate any person's
Service at any time and for any reason.

SECTION 11.  DURATION AND AMENDMENTS.

    (a)  TERM OF THE PLAN.  The Plan, as set forth herein, shall become
effective October 10, 1995, the date the Board of Directors adopted the Plan. 
Notwithstanding the foregoing, no Option granted under the Plan shall become
exercisable unless and until the Plan shall have been approved by the
shareholders of the Company. The Plan shall terminate automatically 10 years
after its initial adoption by the Board of Directors on October 10, 2005, and
may be terminated on any earlier date pursuant to Subsection (b) below.

    (b)  RIGHT TO AMEND OR TERMINATE THE PLAN.  The Board of Directors may
amend, suspend or terminate the Plan at any time and for any reason; provided,
however, that any amendment of the Plan which: (i) materially increases the
number of Shares available for issuance under the Plan (except as provided in
Section 8); (ii) materially changes the class of persons who are eligible for
the grant of ISOs; or (iii) if required by Rule 16b-3 (or any successor) under
the Exchange Act, would materially increase the benefits accruing to
participants under the Plan or would materially modify the requirements as to
eligibility for participation in the Plan, shall be subject to the approval of
the Company's stockholders by the affirmative vote of the holders of a majority
of the securities of the Company present, or represented and entitled to vote at
a duly held stockholders' meeting. Stockholder approval shall not be required
for any other amendment of the Plan.

    (c)  EFFECT OF AMENDMENT OR TERMINATION.  No Shares shall be issued or sold
under the Plan after the termination thereof, except upon exercise of an Option
granted prior to such termination. The termination of the Plan, or any
amendment thereof, shall not affect any Share previously issued or any Option
previously granted under the Plan.

SECTION 12.  INFORMATION TO EMPLOYEES AND CONSULTANTS.

    During such times as Options remain outstanding hereunder, the Company
shall deliver to the Optionees on an annual basis, financial and other
information regarding the Company in accordance with Rule 260.140.46 of Title
10, Chapter 3 of the California Code of Regulations.

                          1996 EMPLOYEE STOCK PURCHASE PLAN


1.  PURPOSE.

    The purpose of this Plan is to provide an opportunity for Employees of
Overland Data, Inc. (the "Corporation") and its Designated Subsidiaries, to
purchase Common Stock of the Corporation and thereby to have an additional
incentive to contribute to the prosperity of the Corporation.  It is the

3.  ELIGIBILITY.

    Any Employee regularly employed on a full-time basis by the Corporation or
by any Designated Subsidiary on an Entry Date shall be eligible to participate
in the Plan with respect to the Option Period commencing on such Entry Date,
provided that the Committee may establish administrative rules requiring that
employment commence some minimum period (e.g., one pay period) prior to an Entry
Date to be eligible to participate with respect to that Entry Date and provided
further that (1) the Board may extend eligibility to part-time Employees
pursuant to criteria and procedures established by the Committee and (2) the
Board may impose an eligibility period on participation of up to two years with
respect to participation on any prospective Entry Date.  The Board may also
determine that a designated group of highly compensated Employees (e.g.,
Employees subject to Section 16(b) of the Securities Exchange Act of 1934) are
ineligible to participate in the Plan.  An Employee shall be considered employed
on a full-time basis unless his or her customary employment is less than 20
hours per week or five months per year.  No Employee may participate in the Plan
if immediately after an option is granted the Employee owns or is considered to
own (within the meaning of Code Section 424(d)), shares of stock, including
stock which the Employee may purchase by conversion of convertible securities or
under outstanding options granted by the Corporation, possessing five percent
(5%) or more of the total combined voting power or value of all classes of stock
of the Corporation or of any of its Subsidiaries.  All Employees who participate
in the Plan shall have the same rights and privileges under the Plan except for
differences which may be mandated by local law and which are consistent with
Code Section 423(b)(5).  The Board may impose restrictions on eligibility and
participation of Employees who are officers and directors to facilitate
compliance with federal or state securities laws or foreign laws. 

4.  PARTICIPATION.

    4.1  An Employee who is eligible to participate in the Plan in accordance
with Section 3 may become a Participant by filing, on a date prescribed by the
Committee prior to an applicable Entry Date, a completed payroll deduction
authorization and Plan enrollment form provided by the Corporation.  An eligible
Employee may authorize payroll deductions at the rate of any whole percentage of
the Employee's Compensation, not to exceed fifteen percent (15%) of the
Employee's Compensation, or such lesser percentage as specified by the Committee
as applied to an Entry Date or Option Period.  All payroll deductions may be
held by the Corporation and commingled with its other corporate funds.  No
interest shall be paid or credited to the Participant with respect to such
payroll deductions except where required by local law as determined by the
Committee.  A separate bookkeeping account for each Participant shall be
maintained by the Corporation under the Plan and the amount of each
Participant's payroll deductions shall be credited to such account.  A
Participant may not make any additional payments into such account.

    4.2  Under procedures established by the Committee, a Participant may
suspend or discontinue participation in the Plan at any time during an Exercise
Period by completing and 


                                         -3-


<PAGE>

filing a new payroll deduction authorization and Plan enrollment form with the
Corporation.  A Participant may increase or decrease his or her rate of payroll
deductions only effective on an Entry Date by filing a new payroll deduction
authorization and Plan enrollment form.  If a new payroll deduction
authorization and Plan enrollment form is not filed with the Corporation, the
rate of payroll deductions shall continue at the originally elected rate
throughout the Option Period unless the Board determines to change the
permissible rate.

    If a Participant suspends participation during an Exercise Period, his or
her accumulated payroll deductions will remain in the Plan for purchase of
shares as specified in Section 6 on the following Exercise Date, but the
Participant will not again participate until he or she completes a new payroll
deduction authorization and Plan enrollment form.  The Committee may establish
rules limiting the frequency with which Participants may suspend and resume
payroll deductions under the Plan and may impose a waiting period on
Participants wishing to resume suspended payroll deductions.  If a Participant
discontinues participation in the Plan, the amount credited to the Participant's
individual account shall be paid to the Participant without interest (except
where required by local law).  In the event any Participant terminates
employment with the Corporation or any Subsidiary for any reason (including
death) prior to the expiration of an Option Period, the Participant's
participation in the Plan shall terminate and all amounts credited to the
Participant's account shall be paid to the Participant or the Participant's
estate without interest (except where required by local law).  Whether a
termination of employment has occurred shall be determined by the Committee. 
The Committee may also establish rules regarding when leaves of absence or
change of employment status (e.g., from full-time to part-time) will be
considered to be a termination of employment, and the Committee may establish
termination of employment procedures for this Plan which are independent of
similar rules established under other benefit plans of the Corporation and its
Subsidiaries.

    In the event of a Participant's death, any accumulated payroll deductions
will be paid, without interest, to the estate of the Participant.

5.  OFFERING.

    5.1  The maximum number of shares of Common Stock which may be issued
pursuant to the Plan shall be 250,000 shares.  The Board may designate any
amount of available shares for offering for any Option Period determined
pursuant to Section 5.2.

    5.2  Each Option Period, Entry Date and Exercise Period shall be determined
by the Board.  The Board shall have the power to change the duration of future
Option Periods or future Exercise Periods, and to determine whether or not to
have overlapping Option Periods, with respect to any prospective offering,
without shareholder approval, and without regard to the expectations of any
Participants.

    5.3  With respect to each Option Period, each eligible Employee who has
elected to participate as provided in Section 4.1 shall be granted an option to
purchase that number of shares of Common Stock which may be purchased with the
payroll deductions accumulated on 


                                         -4-


<PAGE>

behalf of such Employee (assuming payroll deductions at a rate of 15% of
Compensation) during each Exercise Period within such Option Period at the
purchase price specified in Section 5.4 below; provided, however, (1) in no
event shall the Employee be entitled to accrue rights to purchase shares under
the Plan (and all other employee stock purchase plans, as defined in Code
Section 423, of the Corporation and its subsidiaries) at a rate which exceeds
$25,000 of the Fair Market Value of such stock (determined at the time the
option is granted) for any calendar year in which such option is outstanding at
any time, and (2) the maximum shares subject to any option shall in no event
exceed 1,500.

    5.4  The option price under each option shall be the lower of: (i) a
percentage (not less than eighty-five percent (85%)) established by the Board
("Designated Percentage") of the Fair Market Value of the Common Stock on the
Entry Date on which an option is granted, or (ii) the Designated Percentage of
the Fair Market Value on the Exercise Date on which the Common Stock is
purchased.  The Board may change the Designated Percentage with respect to any
future Option Period, but not below eighty-five percent (85%).

    5.5  If the total number of shares of Common Stock for which options
granted under the Plan are exercisable exceeds the maximum number of shares
offered on any Entry Date, the number of shares which may be purchased under
options granted on the Entry Date shall be reduced on a pro rata basis in as
nearly a uniform manner as shall be practicable and equitable.  In this event,
payroll deductions shall also be reduced or refunded accordingly.  If an
Employee's payroll deductions during any Exercise Period exceeds the purchase
price for the maximum number of shares permitted to be purchased under Section
5.3, the excess shall be refunded to the Participant without interest (except
where otherwise required by local law).

    5.6  In the event that the Fair Market Value of the Corporation's Common
Stock is lower on the first day of an Exercise Period within an Option Period
(subsequent "Reassessment Date") than it was on the Entry Date for such Option
Period, all Employees participating in the Plan on the Reassessment Date shall
be deemed to have relinquished the unexercised portion of the option granted on
the Entry Date and to have enrolled in and received a new option commencing on
such Reassessment Date, unless the Board has determined not to permit
overlapping Option Periods or to restrict such transfers to lower price Option
Periods.

6.  PURCHASE OF STOCK.

    Upon the expiration of each Exercise Period, a Participant's option shall
be exercised automatically for the purchase of that number of full shares of
Common Stock which the accumulated payroll deductions credited  to the
Participant's account at that time shall purchase at the applicable price
specified in Section 5.4.


                                         -5-


<PAGE>

7.  PAYMENT AND DELIVERY.

    Upon the exercise of an option, the Corporation shall deliver to the
Participant the Common Stock purchased and the balance of any amount of payroll
deductions credited to the Participant's account not used for the purchase.  The
Board may permit or require that shares be deposited directly with a broker
designated by the Participant (or a broker selected by the Committee) or to a
designated agent of the Company, and the Committee may utilize electronic or
automated methods of share transfer.  The Board may require that shares be
retained with such broker or agent for a designated period of time (and may
restrict dispositions during that period) and/or may establish other procedures
to permit tracking of disqualifying dispositions of such shares or to restrict
transfer of such shares.  To the extent the unused cash balance represents a
fractional share, the unused cash balance credited to the Participant's account
shall be carried over to the next Exercise Period, if the Participant is also a
Participant in the Plan at that time or refunded to the Participant, as
determined by the Committee.  The Corporation shall retain the amount of payroll
deductions used to purchase Common Stock as full payment for the Common Stock
and the Common Stock shall then be fully paid and non-assessable.  No
Participant shall have any voting, dividend, or other stockholder rights with
respect to shares subject to any option granted under the Plan until the option
has been exercised and shares issued.

8.  RECAPITALIZATION.

    If after the grant of an option, but prior to the purchase of Common Stock
under the option, there is any increase or decrease in the number of outstanding
shares of Common Stock because of a stock split, stock dividend, combination or
recapitalization of shares subject to options, the number of shares to be
purchased pursuant to an option, the share limit of Section 5.3 and the maximum
number of shares specified in Section 5.1 shall be proportionately increased or
decreased, the terms relating to the purchase price with respect to the option
shall be appropriately adjusted by the Board, and the Board shall take any
further actions which, in the exercise of its discretion, may be necessary or
appropriate under the circumstances.

    The Board, if it so determines in the exercise of its sole discretion, also
may adjust the number of shares specified in Section 5.1, as well as the price
per share of Common Stock covered by each outstanding option and the maximum
number of shares subject to any individual option, in the event the Corporation
effects one or more reorganizations, recapitalizations, spin-offs, split-ups,
rights offerings or reductions of shares of its outstanding Common Stock.

    The Board's determinations under this Section 8 shall be conclusive and
binding on all parties.

9.  MERGER, LIQUIDATION, OTHER CORPORATION TRANSACTIONS.

    In the event of the proposed liquidation or dissolution of the Corporation,
the Option Period will terminate immediately prior to the consummation of such
proposed transaction, unless otherwise provided by the Board in its sole
discretion, and all outstanding options shall automatically terminate and the
amounts of all payroll deductions will be refunded without interest to the
Participants.

    In the event of a proposed sale of all or substantially all of the assets
of the Corporation, or the merger or consolidation of the Corporation with or
into another corporation, then in the sole discretion of the Board, (1) each
option shall be assumed or an equivalent option shall be substituted by the
successor corporation or parent or subsidiary of such successor corporation, (2)
a date established by the Board on or before the date of consummation of such
merger, consolidation or sale shall be treated as an Exercise Date, and all
outstanding options shall be deemed exercisable on such date or (3) all
outstanding options shall terminate and the accumulated payroll deductions shall
be returned to the Participants.

10. TRANSFERABILITY.

    Options granted to Participants may not be voluntarily or involuntarily
assigned, transferred, pledged, or otherwise disposed of in any way, and any
attempted assignment, transfer, pledge, or other disposition shall be null and
void and without effect.  If a Participant in any manner attempts to transfer,
assign or otherwise encumber his or her rights or interest under the Plan, other
than as permitted by the Code, such act shall be treated as an election by the
participant to discontinue participation in the Plan pursuant to Section 4.2.

11. AMENDMENT OR TERMINATION OF THE PLAN.

    11.1 The Plan shall continue until, January 31, 2007 unless previously
terminated in accordance with Section 11.2.

    11.2 The Board may, in its sole discretion, insofar as permitted by law,
terminate or suspend the Plan, or revise or amend it in any respect whatsoever,
except that, without approval of the shareholders, no such revision or amendment
shall:

         (a)  materially increase the number of shares subject to the Plan,
other than an adjustment under Section 8 of the Plan;

         (b)  materially modify the requirements as to eligibility for
participation in the Plan, except as otherwise specified in this Plan;

         (c)  materially increase the benefits accruing to Participants;


                                         -7-


<PAGE>

         (d)  reduce the purchase price specified in Section 5.4, except as
specified in Section 8;

         (e)  extend the term of the Plan beyond the date specified in Section
11.1; or

         (f)  amend this Section 11.2 to defeat its purpose.

12. ADMINISTRATION.

    The Board shall appoint a Committee consisting of at least two members who
will serve for such period of time as the Board may specify and who may be
removed by the Board at any time.  The Committee will have the authority and
responsibility for the day-to-day administration of the Plan, the authority and
responsibility specifically provided in this Plan and any additional duties,
responsibility and authority delegated to the Committee by the Board, which may
include any of the functions assigned to the Board in this Plan.  The Committee
shall have full power and authority to promulgate any rules and regulations
which it deems necessary for the proper administration of the Plan, to interpret
the provisions and supervise the administration of the Plan, and to take all
action in connection with administration of the Plan as it deems necessary or
advisable, consistent with the delegation from the Board.  Decisions of the
Board and the Committee shall be final and binding upon all participants.  Any
decision reduced to writing and signed by a majority of the members of the
Committee shall be fully effective as if it had been made at a meeting of the
Committee duly held.  The Corporation shall pay all expenses incurred in the
administration of the Plan.  No Board or Committee member shall be liable for
any action or determination made in good faith with respect to the Plan or any
option granted thereunder.

13. COMMITTEE RULES FOR FOREIGN JURISDICTIONS.

    The Committee may adopt rules or procedures relating to the operation and
administration of the Plan in non-United States jurisdictions to accommodate the
specific requirements of local laws and procedures.  Without limiting the
generality of the foregoing, the Committee is specifically authorized to adopt
rules and procedures regarding handling of payroll deductions, payment of
interest, conversion of local currency, withholding procedures and handling of
stock certificates which vary with local requirements.

14. SECURITIES LAWS REQUIREMENTS.

    The Corporation shall not be under any obligation to issue Common Stock
upon the exercise of any option unless and until the Corporation has determined
that: (i) it and the Participant have taken all actions required to register the
Common Stock under the Securities Act of 1933, or to perfect an exemption from
the registration requirements thereof; (ii) any applicable listing requirement
of any stock exchange on which the Common Stock is listed has been satisfied;
and (iii) all other applicable provisions of state, federal and applicable
foreign law have been satisfied.

15. GOVERNMENTAL REGULATIONS.

    This Plan and the Corporation's obligation to sell and deliver shares of
its stock under the Plan shall be subject to the approval of any governmental
authority required in connection with the Plan or the authorization, issuance,
sale, or delivery of stock hereunder.

16. NO ENLARGEMENT OF EMPLOYEE RIGHTS.

    Nothing contained in this Plan shall be deemed to give any Employee the
right to be retained in the employ of the Corporation or any Designated
Subsidiary or to interfere with the right of the Corporation or Designated
Subsidiary to discharge any Employee at any time.

17. GOVERNING LAW.

    This Plan shall be governed by California law.

18. EFFECTIVE DATE.

    This Plan shall be effective on the first date in 1997 in which the Common

approval of the shareholders of the Corporation within 12 months of its adoption
by the Board of Directors.
