                                    SUMMARY
 
     This Joint Proxy Statement/Prospectus relates to the proposed merger (the
"Merger") of Atari Corporation, a Nevada corporation ("Atari"), with and into
JTS Corporation, a Delaware corporation ("JTS"), and certain related matters.
Upon consummation of the Merger, the separate existence of Atari will cease and
JTS will remain as the surviving corporation. Such corporation is sometimes
referred to herein as the "Combined Company." Unless otherwise indicated, all
references herein to Atari include Atari and its subsidiaries, and all
references herein to JTS include JTS and its subsidiaries, including Moduler
Electronics (India) Pvt. Ltd. ("Moduler Electronics").
 
     The following is intended as a summary of the information contained in this
Joint Proxy Statement/Prospectus, is not intended to be a complete statement of
all material features of the proposals to be voted on, and is qualified in its
entirety by the more detailed information appearing elsewhere in this Joint
Proxy Statement/Prospectus and attached Appendices, including the Amended and
Restated Agreement and Plan of Reorganization attached hereto as Appendix A (the
"Merger Agreement") and the forms of Voting Agreement attached hereto as
Appendices B-1 and B-2 (the "Voting Agreements"), all of which are important and
should be carefully reviewed.
 
     In May 1996, the JTS stockholders approved, subject to the closing of the
Merger, (i) an amendment and restatement of the JTS Certificate of Incorporation
to, among other things, increase the authorized shares of JTS Common Stock, and
(ii) an amendment and restatement of the JTS Bylaws. In addition, the holders of
the JTS Series A Preferred Stock elected to convert all outstanding shares of
JTS Series A Preferred Stock into shares of JTS Common Stock immediately prior
to the closing of the Merger. Unless otherwise indicated, all information
contained herein reflects the foregoing changes to the Certificate of
Incorporation and Bylaws of JTS and the conversion of all outstanding shares of
JTS Series A Preferred Stock into shares of JTS Common Stock.
 
     This Joint Proxy Statement/Prospectus contains forward-looking statements
within the meaning of Section 27A of the Securities Act of 1933 and Section 21E
of the Securities Exchange Act of 1934. Actual results could differ materially
from those projected in the forward-looking statements as a result of the risk
factors set forth in this Joint Proxy Statement/Prospectus.
 
                       THE PARTIES TO THE PROPOSED MERGER
 
     Atari Corporation.  Atari markets video game consoles, related software and
peripheral products and multimedia entertainment software for various platforms.
Atari's principal products are its Jaguar 64-bit interactive multimedia
entertainment system, Jaguar software and Jaguar peripherals. Due to
disappointing sales of Jaguar and related products, in late 1995 Atari
significantly downsized its Jaguar operations, and decided to focus its efforts
on selling its inventory of Jaguar and related products and to emphasize its
licensing and development activities related to multimedia entertainment
software for various platforms.
 
     Atari was incorporated in Nevada in May 1984. Atari maintains its executive
offices at 455 South Mathilda Avenue, Sunnyvale, California 94086, and its
telephone number is (408) 328-0900.
 
     JTS Corporation  JTS designs, manufactures and markets hard disk drives for
the personal computer industry. JTS has developed two product families of hard
disk drives: the 3-inch form factor Nordic product family for notebook computers
and the 3.5-inch form factor Palladium product family for desktop personal
computers. In addition, JTS is developing a 5.25-inch form factor disk drive for
desktop personal computers.
 
     JTS was incorporated in Delaware in February 1994. JTS maintains its
executive offices at 166 Baypointe Parkway, San Jose, California 95134, and its
telephone number is (408) 468-1800.
 
                     ATARI SPECIAL MEETING OF STOCKHOLDERS
 
     Time, Date, and Purpose.  The Atari Special Meeting of Stockholders (the
"Atari Special Meeting") will be held at the offices of Wilson Sonsini Goodrich
& Rosati, P.C., 650 Page Mill Road, Palo Alto, California, legal counsel to
Atari, on Tuesday, July 30, 1996 at 9:00 a.m. The purpose of the Atari Special
Meeting is for Atari stockholders to consider and vote upon a proposal to
approve the Merger and the Merger Agreement.
 
                                        6
<PAGE>   11
 
     Record Date; Stockholder Approval.  The record date for stockholders of
Atari entitled to vote at the Atari Special Meeting is June 28, 1996 (the "Atari
Record Date"). Approval of the Merger and the Merger Agreement requires the
affirmative vote of holders of a majority of the shares of Atari Common Stock
outstanding on the Atari Record Date.
 
                      JTS SPECIAL MEETING OF STOCKHOLDERS
 
     Time, Date and Purpose.  The JTS Special Meeting of Stockholders (the "JTS
Special Meeting") will be held at the offices of JTS located at 166 Baypointe
Parkway, San Jose, California, on Tuesday, July 30, 1996 at 9:00 a.m. The
purpose of the JTS Special Meeting is for JTS Stockholders to consider and vote
upon a proposal to approve the Merger and the Merger Agreement.
 
     Record Date; Stockholder Approval.  The record date for stockholders of JTS
entitled to vote at the JTS Special Meeting is June 18, 1996 (the "JTS Record
Date"). Approval of the Merger and the Merger Agreement requires the affirmative
vote of holders of (a) a majority of the shares of JTS Common Stock and JTS
Series A Preferred Stock outstanding on the JTS Record Date, voting together,
(b) a majority of the shares of JTS Common Stock outstanding on the JTS Record
Date, voting separately as a class, and (c) at least two-thirds of the shares of
JTS Series A Preferred Stock outstanding on the JTS Record Date, voting
separately as a class.
 
                                   THE MERGER
 
     Effect of the Merger.  Upon consummation of the Merger, Atari will be
merged with and into JTS, the separate existence of Atari will cease, JTS will
remain as the surviving corporation and all of the rights, privileges, powers,
franchises, properties, assets, liabilities and obligations of Atari will be
vested in JTS. At the Effective Time (as such term is defined below), each
outstanding share of Atari Common Stock will be converted into one share of JTS
Common Stock. See "The Proposed Merger and Related Transactions -- Summary of
the Merger Agreement -- Manner and Basis of Converting Atari Common Stock."
 
     Immediately after giving effect to the Merger, assuming that no
stockholders of JTS perfect appraisal or dissenters' rights and assuming no
exercise of outstanding options to purchase Atari Common Stock or JTS Common
Stock after June 28, 1996, the shares of JTS Common Stock issued in the Merger
upon conversion of the Atari Common Stock will represent approximately 62% of
the outstanding shares of the Combined Company.
 
     If the Merger does not receive all necessary stockholder approvals or the
Merger is not consummated for any other reason, Atari currently intends to
continue operating its business as presently conducted and will focus on its
existing licensing and software development activities. Atari also expects to
evaluate other strategic business opportunities. If the Merger does not receive
all necessary stockholder approvals or the Merger is not consummated for any
other reason, JTS expects to continue to operate its business as currently
planned and to pursue alternative sources of funding to provide necessary
working capital and to permit the expansion of its operations.
 
     Atari Board of Directors.  The Board of Directors of Atari has unanimously
approved the Merger Agreement and the Merger and has determined that the Merger
is fair to, and in the best interests of Atari and its stockholders. The Atari
Board of Directors unanimously recommends approval of the Merger Agreement and
the Merger by the Atari stockholders. The primary factors considered and relied
upon by the Atari Board of Directors in reaching its recommendation are referred
to in "The Proposed Merger and Related Transactions -- Recommendation of the
Board of Directors of Atari."
 
     JTS Board of Directors.  The Board of Directors of JTS has unanimously
approved the Merger Agreement and the Merger and has determined that the Merger
is fair to, and in the best interests of JTS and its stockholders. The JTS Board
of Directors unanimously recommends approval of the Merger Agreement and the
Merger by the JTS stockholders. The primary factors considered and relied upon
by the JTS Board of
 
                                        7
<PAGE>   12
 
Directors in reaching its recommendation are referred to in "The Proposed Merger
and Related Transactions -- Recommendation of the Board of Directors of JTS."
 
   
     Stockholder Votes Required.  To approve the Merger, a majority of the
shares of Atari Common Stock must approve the Merger. It is expected that all of
the shares of Atari Common Stock owned by directors and executive officers of
Atari and their affiliates will be voted for approval of the Merger. These
shares constitute approximately 43% of the total number of outstanding shares of
Atari Common Stock. Approval of the Merger also requires the vote of holders of
a majority of the JTS Common Stock and Series A Preferred Stock (voting
together), a majority of the JTS Common Stock (voting separately as a class) and
at least two-thirds of the JTS Series A Preferred Stock (voting separately as a
class). It is expected that all of the shares of JTS Common Stock and Series A
Preferred Stock owned by directors and executive officers of JTS and their
affiliates will be voted for approval of the Merger. These shares constitute
approximately 99% of the total number of JTS Common Stock and 48% of the total
number of JTS Series A Preferred Stock.
    
 
     Opinion of Montgomery Securities.  Montgomery Securities ("Montgomery"),
financial advisor to Atari, has delivered to the Atari Board of Directors its
written opinion, dated February 5, 1996, to the effect that the conversion ratio
of Atari Common Stock into JTS Common Stock is fair to Atari from a financial
point of view, as of that date. Reference is made to the full text of the
opinion, a copy of which is attached hereto as Appendix C. See "The Proposed
Merger and Related Transactions -- Background and Board Recommendations -- Atari
Financial Advisor."
 
     Effective Time.  The Merger will be consummated on the date that the
Certificate of Merger is filed with the Nevada Secretary of State and the
Delaware Secretary of State (the "Effective Time"). The Effective Time is
expected to occur as soon as practicable after approval of the Merger and the
Merger Agreement at the Atari and JTS Special Meetings and satisfaction or
waiver of the conditions precedent to the Merger, as set forth in the Merger
Agreement.
 
     Listing of Common Stock.  The Atari Common Stock is listed on the American
Stock Exchange under the symbol "ATC." There is no public market for the JTS
Common Stock or the JTS Series A Preferred Stock. Upon consummation of the
Merger, it is expected that the JTS Common Stock will be listed on the American
Stock Exchange under the symbol "JTS", and that the Atari Common Stock will be
delisted from the American Stock Exchange.
 
     Exchange of Shares.  Exchange of Atari Common Stock certificates for JTS
Common Stock certificates will be made upon surrender of Atari Common Stock
certificates to Registrar and Transfer Company, Cranford, NJ, as exchange agent.
Atari stockholders will be provided with a letter of transmittal and related
materials for the exchange of their certificates after the Effective Time.
 
     ATARI STOCKHOLDERS SHOULD NOT SUBMIT THEIR STOCK CERTIFICATES UNTIL THEY
RECEIVE INSTRUCTIONS AND TRANSMITTAL FORMS AFTER COMPLETION OF THE MERGER.
 
     Assumption of Atari Options.  Upon consummation of the Merger, each option
to purchase Atari Common Stock then outstanding will be assumed by JTS and will
be converted automatically into an option to purchase the same number of shares
of JTS Common Stock at an exercise price per share equal to the exercise price
per share of the Atari option. The other terms of the Atari options, including
vesting schedules, will remain unchanged.
 
     Registration Statement on Form S-8.  Within five days following the closing
of the Merger, JTS will file a Registration Statement on Form S-8 with the
Commission with respect to the shares of JTS Common Stock issuable upon exercise
of the assumed Atari options and JTS options granted or available for grant
under the JTS amended and restated 1995 Stock Option Plan (the "Restated Plan").
 
     Assumption of Atari Debentures.  Upon consummation of the Merger, all of
Atari's obligations under its outstanding 5 1/4% convertible subordinated
debentures due April 29, 2002 (the "Atari Debentures") will be assumed by JTS.
The Atari Debentures are presently convertible into Atari Common Stock at a
conversion
 
                                        8
<PAGE>   13
 
price of $16.3125 per share, and following the Merger will be convertible into
JTS Common Stock at the same conversion price. The other terms of the Atari
Debentures will remain unchanged.
 
     Conditions to Consummation of the Merger.  Consummation of the Merger is
subject to various conditions precedent, including Atari and JTS stockholder
approvals of the Merger and the Merger Agreement, the receipt of certain
consents and approvals from various third parties and governmental agencies,
receipt of opinions of counsel regarding certain legal matters, including
opinions of tax counsel to the effect that the Merger will qualify as a
reorganization under Section 368(a) of the Internal Revenue Code of 1986, as
amended (the "Code"), and that stockholders of JTS holding not more than 5% of
the JTS capital stock entitled to vote at the JTS Special Meeting shall be
entitled to exercise appraisal or dissenters' rights. Each of the parties to the
Merger Agreement may, at its option, waive compliance with any condition
precedent to its obligation to consummate the Merger. In the event that a
condition to consummation of the Merger is not satisfied, each party whose
obligation to consummate the Merger is subject to satisfaction of such condition
intends to evaluate whether it would be in the best interests of that party and
its stockholders to waive the condition and consummate the Merger. In the event
that a condition to consummation of the Merger is waived by one of the parties
and applicable law requires that party to resolicit stockholder approval,
stockholder approval will be resolicited prior to consummation. For example,
stockholder approval would be resolicited in the event that such waiver would
result in an alteration or change in (a) the amount or kind of consideration to
be received by the Atari stockholders in exchange for their shares of Atari
Common Stock as a result of the Merger, (b) any term of the Certificate of
Incorporation of JTS to be effected by the Merger or (c) any of the terms and
conditions of the Merger Agreement if such alteration or change would adversely
affect the holders of JTS Common Stock or Atari Common Stock. Neither Atari nor
JTS presently has any intention of waiving any terms or conditions of the Merger
Agreement.
 
     Termination and Amendment of Merger Agreement.  The Merger Agreement may be
terminated, notwithstanding its approval by the stockholders of Atari or JTS,
(a) by mutual written agreement of the parties, (b) by Atari if there has been a
breach of any representation, warranty, covenant or agreement in the Merger
Agreement on the part of JTS which has or can reasonably be expected to have a
material adverse effect on JTS and its subsidiaries, taken as a whole, or upon
the occurrence of certain other events, (c) by JTS if there has been a breach of
any representation, warranty, covenant or agreement in the Merger Agreement on
the part of Atari which has or can reasonably be expected to have a material
adverse effect on Atari and its subsidiaries, taken as a whole, or upon the
occurrence of certain other events, or (d) by Atari or JTS if (i) the closing of
the Merger does not occur by July 31, 1996, (ii) there should be a final
nonappealable order of federal or state court preventing consummation of the
Merger, (iii) the JTS or Atari stockholders do not approve the Merger at their
respective stockholders' meetings, or (iv) the Atari Board of Directors shall
have accepted, approved or recommended to the Atari stockholders a superior
acquisition proposal. In addition, the Merger Agreement may be amended by the
mutual consent of the parties at any time prior to the Effective Time, whether
or not the Merger has been approved by the stockholders of Atari or JTS but,
after any such approval, no amendment will be made which by law requires further
approval by such stockholders without such further approval. See "The Proposed
Merger and Related Transactions -- Summary of the Merger Agreement --
Termination, Amendment and Waiver."
 
     Availability of Appraisal and Dissenters' Rights.  Under Section 262 of the
Delaware General Corporation Law ("DGCL"), a copy of which is attached hereto as
Appendix D-1, and Chapter 13 of the California General Corporation Law ("CGCL"),
a copy of which is attached hereto as Appendix D-2, stockholders of JTS may,
under certain circumstances and by following prescribed statutory procedures,
have the right to seek appraisal of the "fair value" of such stockholders'
shares. The failure of a stockholder choosing to execute such right to follow
such procedures may result in termination or waiver of appraisal and dissenters'
rights. See "The Proposed Merger and Related Transactions -- Appraisal and
Dissenters' Rights." The obligation of Atari to consummate the Merger is subject
to the condition that the holders of not more than 5% of the JTS capital stock
entitled to vote at the JTS Special Meeting shall have asserted and not
effectively withdrawn or lost the right to obtain the fair value of such
holders' shares pursuant to the applicable provisions of the DGCL and CGCL.
 
                                        9
<PAGE>   14
 
     The stockholders of Atari are not entitled to statutory appraisal or
dissenters' rights pursuant to the applicable provisions of the Nevada General
Corporation Law ("NGCL").
 
     Resale of JTS Common Stock.  The shares of JTS Common Stock to be issued to
former holders of Atari Common Stock in the Merger have been registered under
the Securities Act of 1933, as amended (the "Securities Act"), by a Registration
Statement on Form S-4, of which this Joint Proxy Statement/Prospectus is a part,
thereby allowing such shares of JTS Common Stock to be traded without
restriction under the Securities Act by all such holders not deemed to be
"affiliates" (as such term is defined for purposes of Rule 145 promulgated under
the Securities Act) of Atari prior to the consummation of the Merger. See "The
Proposed Merger and Related Transactions -- Certain Other Items Related to the
Merger -- Resale of JTS Common Stock."
 
     Certain Federal Income Tax Considerations.  The obligations of each of
Atari and JTS to consummate the Merger are conditioned upon receipt of opinions
from their respective legal counsel that the Merger will qualify as a
reorganization for federal income tax purposes under Section 368(a) of the Code
and that, accordingly, no gain or loss ordinarily will be recognized by JTS or
Atari nor by Atari stockholders upon their receipt of shares of JTS Common Stock
in exchange for their shares of Atari Common Stock, except to the extent of cash
received for fractional shares, if any. Such legal opinions will be subject to
certain limitations and qualifications and will be based upon certain factual
assumptions and representations. Furthermore, such opinions will not be binding
on the Internal Revenue Service. In view of the complexities of federal income
and other tax laws, each Atari and JTS stockholder should consult with their own
tax advisors as to the specific tax consequences of the Merger, including the
applicable federal, state, local and foreign tax consequences to them of the
Merger in their specific circumstances.
 
     Accounting Treatment.  For accounting purposes, the Merger is treated as if
Atari acquired JTS. A new basis of accounting will be established for the assets
and liabilities of JTS. The new basis reflects the allocation of the purchase
price to the JTS assets and liabilities on the basis of their fair values at the
time the proposed transaction was announced. The aggregate purchase price to be
allocated includes the outstanding common stock of JTS, valued using $2.50 per
share which is the representative value of the Atari Common Stock at the time
the proposed transaction was announced, as well as the value of JTS options and
warrants and direct costs of the acquisition. Subsequent to the Merger, the
financial statements of the Combined Company will reflect the combined financial
position, results of operations and cash flows of Atari and JTS based on the new
basis of accounting for JTS and the historic cost basis of Atari. Pro forma
combined condensed financial statements are presented herein giving effect to
the Merger as if the transaction occurred, for purposes of the pro forma
combined financial position of the Combined Company, on March 31, 1996, and for
purposes of the pro forma combined results of operations of the Combined
Company, on the first day of each of the periods presented. The allocation of
the purchase price in the pro forma statements will be revised as updated
information becomes available at the Effective Time. Under the purchase
accounting method, giving effect to the Merger, existing technology and goodwill
in the amount of approximately $22.0 million and $11.7 million, respectively,
are expected to be recognized by the Combined Company. It is anticipated that
the Combined Company will amortize the resulting existing technology and
goodwill over periods of three and seven years, respectively, which will have an
adverse effect on its results of operations. In addition, upon the consummation
of the Merger, in the third quarter of calendar year 1996, the Combined Company
expects to expense approximately $100.0 million of purchased in-process
technology. See "Unaudited Pro Forma Combined Condensed Financial Statements."
 
     Atari Loan to JTS.  In connection with the merger, on February 13, 1996,
Atari loaned $25.0 million to JTS pursuant to a Subordinated Secured Convertible
Promissory Note (the "Note") which is secured by substantially all of the assets
of JTS. Interest accrues on the unpaid principal amount of the Note at the rate
of 8.5% per annum. The Note was amended in June 1996 to increase the amount lent
pursuant thereto to $30.0 million. The Note provides that JTS shall repay the
outstanding principal and interest under the Note on September 30, 1996 if the
Merger has not occurred prior to such time. In the event that the Merger
Agreement is terminated, either party may, under certain conditions, elect to
convert the outstanding indebtedness under the Note into shares of JTS Series A
Preferred Stock. The Note is expressly subordinated
 
                                       10
<PAGE>   15
 
to outstanding indebtedness in connection with JTS' primary bank loan agreement,
up to an amount of $5.0 million at any given time.
 
     Related Transactions.  In connection with the Merger, the parties have
effected or will effect a number of related party transactions, including the
grant of certain stock options by JTS. In addition, pursuant to the Voting
Agreements, certain stockholders of Atari and JTS have agreed to vote the shares
of Atari Common Stock, JTS Common Stock and JTS Series A Preferred Stock held by
them for the approval of the Merger and the Merger Agreement. See "The Proposed
Merger and Related Transactions -- Related Transactions."
 
     Interests of Certain Persons.  Certain members of the management of JTS
have certain interests in connection with the Merger that are in addition to the
interests of stockholders of JTS generally. See "The Proposed Merger and Related
Transactions -- Certain Other Items Related to the Merger -- Interests of
Certain Persons in the Merger."
 
     Differences in Rights of Stockholders.  Upon consummation of the Merger,
stockholders of Atari will become stockholders of JTS. As a result, their rights
as stockholders, which are now governed by the NGCL and the Articles of
Incorporation and Bylaws of Atari, will be governed by the DGCL and the
Certificate of Incorporation and Bylaws of the Combined Company. Because of
certain differences between the provisions of the NGCL and the Articles of
Incorporation and Bylaws of Atari, on the one hand, and the DGCL and the
Certificate of Incorporation and Bylaws of the Combined Company, on the other
hand, the current rights of the stockholders of Atari will change after the
Merger. See "Comparison of Rights of Stockholders of Atari and JTS."
 
                          MARKET PRICE OF COMMON STOCK
 
   
     Atari Common Stock is traded on the American Stock Exchange under the
symbol "ATC." There is no public market for the JTS Common Stock or the JTS
Series A Preferred Stock. The closing price per share of Atari Common Stock was
$1 7/8 at February 12, 1996, the last day of trading before the announcement of
the Merger, and $5.625 at July 12, 1996, the latest trading day before the
mailing of this Joint Proxy Statement/ Prospectus.
    
 
                                  RISK FACTORS
 
     The consummation of the Merger and the Merger Agreement and an investment
in the shares of JTS Common Stock each involve a high degree of risk. Before
voting on the Merger, stockholders of Atari and JTS should carefully consider
the information set forth in "Risk Factors."

       ATARI AND JTS UNAUDITED SELECTED PRO FORMA COMBINED FINANCIAL DATA
 
     The following table sets forth the unaudited selected pro forma combined
financial data for the periods and as of the date indicated which are derived
from the Unaudited Pro Forma Combined Condensed Financial Statements (the "Pro
Forma Financial Statements") which present the pro forma combined condensed
financial position and results of operations of Atari and JTS. The unaudited pro
forma condensed combined balance sheet has been prepared as if the Merger, which
will be accounted for as a purchase of JTS by Atari, was consummated as of March
31, 1996. The unaudited pro forma condensed combined statements of operations
give effect to the Merger as if the acquisition were completed at the beginning
of the periods presented. The Pro Forma Financial Statements combine the
historical results of operations of Atari for the year ended December 31, 1995
with the JTS and Moduler Electronics unaudited pro forma combined results of
operations for the year ended January 28, 1996 and the historical financial
position and results of operations of Atari as of and for the quarter ended
March 31, 1996 with the historical financial position and results of operations
of JTS as of and for the quarter ended April 28, 1996.
 
     The unaudited selected pro forma combined financial data is provided for
illustrative purposes only and is not necessarily indicative of the combined
financial position or combined results of operations that would have been
reported had the Merger occurred on the dates indicated, nor do they represent a
forecast of the combined financial position or results of operations for any
future period. No pro forma adjustments have been included herein which reflect
potential effects of (a) efficiencies which may be obtained by combining Atari
and JTS operations or (b) costs of restructuring, integrating or consolidating
their operations. The unaudited selected pro forma combined financial data
should be read in conjunction with the Pro Forma Financial Statements and
related notes, and the historical financial statements and related notes of
Atari and JTS which are included elsewhere herein. All amounts are stated in
thousands, except for per share amounts.

                           COMPARATIVE PER SHARE DATA
 
     The following table sets forth certain historical per share data of Atari
and pro forma combined per share data giving effect to the JTS and Moduler
Electronics combination and the Atari and JTS Merger as if the combination and
Merger were effective January 1, 1995 for the loss per common share data for the
year ended December 31, 1995 and January 1, 1996 for the loss per common share
data for the quarter ended March 31, 1996, and March 31, 1996 for book value per
common share data using the purchase method of accounting. The pro forma
combined per share data are derived from financial information in the Pro Forma
Financial Statements. The pro forma data are not necessarily indicative of
amounts which would have been achieved had the Merger been consummated at the
beginning of the period presented and should not be construed as representative
of future operations. This data should be read in conjunction with the Pro Forma
Financial Statements and notes thereto included elsewhere herein, and the
separate historical financial statements and notes thereto of Atari, JTS and
Moduler Electronics, also included elsewhere herein.

                                  RISK FACTORS
 
     The following factors should be considered carefully in evaluating the
proposals to be voted on at the Atari Special Meeting and the JTS Special
Meeting. For periods following the Merger, references to the products, business,
results of operations or financial condition of JTS should be considered to
refer to JTS and Atari, unless the context otherwise requires.
 
RISK FACTORS RELATED TO THE BUSINESS OF ATARI
 
     Significant Operating Losses; Disappointing Sales of Jaguar
Products.  Atari has incurred significant operating losses for the past five
fiscal years. Most recently, Atari incurred an operating loss of $53.7 million
for fiscal 1995 and $24.0 million for fiscal 1994. Over the past several years,
Atari has undergone significant change. In 1992 and 1993, Atari significantly
downsized its operations, decided to exit the computer products business and
focused its efforts on its video game business. While restructuring, Atari
developed its 64-bit Jaguar interactive multimedia entertainment system, which
was introduced in the fourth quarter of 1993. For 1995 and 1994, net sales of
Jaguar and related software and accessories were $9.9 million and $29.3 million,
respectively, and were substantially below Atari's expectations. Atari
attributes the poor performance of Jaguar products to a number of factors
including (i) extensive delays in development of software for Jaguar which
resulted in reduced orders due to consumer concern as to when titles for the
platform would be released and how many titles would ultimately be available,
and (ii) the introduction of competing products by Sega Enterprises, Ltd.
("Sega") and Sony Corporation ("Sony") in May 1995 and September 1995,
respectively. Due to disappointing sales and competitive pricing pressures,
Atari reduced the suggested retail price of the Jaguar console from its original
price of $249.99 to its current price of $99.99. As a result of Jaguar price
reductions, the substantial curtailment of sales and marketing activities for
the Jaguar and the substantial curtailment of efforts by Atari and independent
software developers to develop additional software titles for the Jaguar, Atari
expects sales of Jaguar and related products to decline substantially in 1996
and thereafter.
 
     The failure of Jaguar to achieve commercial acceptance has had a severe
financial impact on Atari. In this regard, Atari reported a net loss of $49.6
million for 1995 compared to net income of $9.4 million in 1994, and Atari's net
revenues declined from $38.7 million in 1994 to $14.6 million in 1995.
Accelerated amortization and write-offs of software development costs in the
amount of $16.6 million and inventory write-downs of $12.6 million contributed
significantly to the 1995 loss. The net loss for the first quarter of 1996 was
$800,000 compared to a net loss of $4.4 million for the first quarter of 1995
and Atari's net revenues declined from $4.9 million for the first quarter of
1995 to $1.3 million for the comparable period in 1996. The net loss in the
first quarter of 1996 was impacted by the $6.3 million gain from sale of
marketable securities offset by a $5.0 million inventory write-down in the
quarter. In response to these losses, the number of employees at Atari was
reduced from 101 at December 31, 1994 to 73 at December 31, 1995 and to 31 at
March 31, 1996. In addition to reductions in the Atari workforce, this
downsizing resulted in significant curtailment of research and development and
sales and marketing activities for Jaguar and related products. Accordingly,
Atari has decided to focus its efforts on selling its inventory of Jaguar and
related products and to emphasize its existing licensing and development
activities related to multimedia entertainment software for various platforms.
See "Information Regarding Atari Corporation -- Business of Atari."
 
     Risk of Additional Inventory Write-Downs.  From the introduction of Jaguar
in late 1993 through May 1996, Atari sold approximately 135,000 units of Jaguar.
As of December 31, 1995, Atari had approximately 100,000 units of Jaguar in
inventory and the value of Jaguar inventory and related software was
approximately $9.9 million. Due to disappointing sales of Jaguar and increased
competition from products introduced by Sega and Sony, Atari reduced the
suggested retail price of Jaguar to $99.99 and recorded an inventory write-down
of $12.6 million in 1995. Despite the introduction of four additional game
titles in the first quarter of 1996, sales of Jaguar and related software have
remained disappointing due to uncertainty about Atari's commitment to the Jaguar
platform, increased price competition and pending competitive product
introductions. As a result of continued disappointing sales, management revised
estimates and wrote-down inventory by an additional $5.0 million in the first
quarter of 1996. As of the end of May 1996, Atari had approximately 90,000 units
of Jaguar in inventory.
 
                                       16

     Volume sales of Jaguar and related software in 1996 have consisted
primarily of a large order from a new European customer. Atari is also pursuing
wholesale sales channels in the U.S. as well as licensing opportunities. There
can be no assurance that Atari's substantial unsold inventory of Jaguar and
related software can be sold at current or reduced prices, if at all. In
addition, any further decrease in the value of such inventory could result in
additional inventory write-downs by Atari.
 
     Risk of Potential Liabilities.  In connection with the restructuring of
Atari's business in 1992 and 1993 and Atari's decision in late 1995 to
significantly downsize its Jaguar operations, Atari has terminated and plans to
terminate numerous contracts and business relationships, including several
related to software development activities. Although Atari does not regard such
contracts or business relationships, either individually or in the aggregate, as
material, the termination of contracts and relationships has, from time to time,
resulted in litigation, diverting management and financial resources. There can
be no assurance that the parties to such contracts will not commence or threaten
to commence litigation related to such contracts. Any such litigation or
threatened litigation would further divert management and financial resources
and could have a material adverse effect on Atari's business, operating results
and financial condition. In addition, Atari holds several properties for sale,
some of which are currently being leased. The ownership and use of such
properties subjects Atari to numerous risks, including risks of environmental
and personal injury liabilities. Although Atari is attempting to sell certain of
such properties, such sales are not expected to eliminate all the risks
associated with Atari's ownership of such properties, including potential
environmental liabilities and ongoing indemnification and other contractual
obligations. At present, Atari has no such indemnification obligations and is
not aware of any such environmental liability.
 
     Intellectual Property.  Atari has exclusive use of its "Atari" name and
"Fuji" logo in all areas other than coin-operated arcade video game use. Atari
also has a portfolio of other intellectual properties including patents,
trademarks, and copyrights associated with its video game and computer
businesses. Atari believes its patents, trademarks and other intellectual
property are important assets. As of May 31, 1996, Atari held over 150 patents
in the United States and other jurisdictions which expire from 1996 to 2010 and
had applications pending for three additional patents. There can be no assurance
that any of these patent rights will be upheld in the future or that Atari will
be able to preserve any of its other intellectual property rights. Atari has in
the past received communications from third parties asserting rights to certain
of its intellectual property. Atari has also been involved in several major
lawsuits regarding its intellectual property, including a suit with Nintendo of
America, Inc. and its affiliates ("Nintendo.") which was settled in March 1994
and a suit with Sega which was settled in September 1994. In the event any third
party were to make a valid claim with respect to Atari's intellectual property
and a license were not available on commercially reasonable terms, Atari's
business, financial condition and results of operations would be materially and
adversely affected. Litigation, which has in the past resulted and could in the
future result in substantial costs and diversion of resources, may also be
necessary to enforce Atari's patents or other intellectual property rights or to
defend against third party infringement claims. The occurrence of litigation
relating to patent infringement or other intellectual property matters,
regardless of the outcome, could have a material adverse effect on Atari's
business, financial condition and results of operations.
 
     Competition.  The video game business is intensely competitive. Since its
introduction in late 1993, the Jaguar, Atari's principal product, has failed to
achieve broad market acceptance. Atari does not expect that the Jaguar, even at
its substantially reduced price, will ever become a broadly accepted video game
console, or that Jaguar technology will be broadly adopted by software title
developers. The video game industry is also characterized by unpredictable and
rapid shifts in the popularity of certain platforms, by severe price
competition, and by frequent new technology and product introductions. In this
regard, numerous companies have introduced or have developed and are expected to
introduce video game consoles that are or may become competitive with Jaguar. In
addition, an increasing number of entertainment titles are being developed for
or ported to the PC platform. Most of Atari's competitors have greater
experience and expertise in 3D graphics and multimedia technology and have
substantially greater engineering, marketing and financial resources than Atari.

     Risks of Bridge Loan to JTS.  In February 1996, Atari loaned $25.0 million
to JTS in connection with the Merger, and in June 1996 the loan amount was
increased to $30.0 million. The loan is due to be repaid by JTS in September
1996 and is secured by substantially all of the assets of JTS. Atari's security
interest in such assets is junior to existing security interests in favor of a
bank and certain equipment lessors. In the event the Merger is not consummated,
there can be no assurance that Atari's security interest in such assets will
adequately protect Atari in the event JTS is unable to repay the loan. In
addition, the loan is convertible into shares of JTS Series A Preferred Stock at
the option of Atari or JTS upon the occurrence of certain conditions, including
a breach of the Merger Agreement by the other party. In the event such
conversion occurs, Atari would hold a significant percentage of JTS' outstanding
equity securities and would be subject to the numerous risks associated with
JTS' business. There can be no assurance that such securities would be freely
tradeable at the time of conversion, if ever. See "Risk Factors Related to the
Business of JTS."
 
     Reduction in Voting Control; Loss of Management Control.  Upon the closing
of the Merger, the stockholders of JTS prior to the Merger will own
approximately 38% of the outstanding voting securities of the Combined Company
(assuming no exercise of options or warrants after June 28, 1996). In addition,
it is anticipated that the executive officers of JTS prior to the Merger will
continue to serve as executive officers of the Combined Company and that none of
the executive officers of Atari prior to the Merger will serve as executive
officers of the Combined Company. Further, the Board of Directors of the
Combined Company will include five current JTS directors and two current Atari
directors. The current JTS officers and directors and their affiliates will own
approximately 23% of the outstanding voting securities of the Combined Company
(assuming no exercise of options or warrants after June 28, 1996). As a result,
such stockholders, acting together, could exert significant influence over
matters requiring approval of the stockholders of the Combined Company. Such
matters include the election of the members of the Combined Company's Board of
Directors, proxy contests, mergers involving the Combined Company, tender offers
or other transactions that could afford stockholders of the Combined Company the
opportunity to realize a premium over the then prevailing market price of the
Common Stock of the Combined Company.
 
RISK FACTORS RELATED TO THE BUSINESS OF JTS
 
     Limited Operating History; History of Operating Losses; Working Capital
Deficit; Independent Accountants' Report with Explanatory Paragraph.  JTS was
incorporated in February 1994 and did not commence production of hard disk
drives until October 1995. JTS experienced operating losses for its fiscal years
ended January 29, 1995 and January 28, 1996 of $5.2 million and $31.6 million,
respectively, which resulted from the substantial costs associated with the
design, development and marketing of new products, the establishment of
manufacturing operations and the development of a supplier base. At January 28,
1996, JTS had a working capital deficit of $15.2 million and a negative net
worth of $38.6 million. JTS has yet to generate significant revenues and cannot
assure that any level of future revenues will be attained or that JTS will
achieve or maintain successful operations in the future. Such factors have
raised substantial doubt about the ability of JTS to continue its operations
without achieving successful future operations or obtaining financing to meet
its working capital needs, neither of which can be assured. The report of
independent public accountants on JTS' financial statements includes an
explanatory paragraph describing uncertainties concerning the ability of JTS to
continue as a going concern. See "Notes to JTS Financial Statements."
 
     Need For Additional Financing; Current Financing Plans.  The hard disk
drive business is extremely capital intensive, and JTS anticipates that it will
need significant additional financing resources in the near term for facilities
expansion, capital expenditures, working capital, research and development and
vendor tooling. In this regard, JTS has held discussions with investment banking
firms regarding the possibility of raising additional capital through the
issuance of debt or equity securities. In June 1996, JTS retained an investment
banking firm to advise JTS with respect to the private issuance of between
$50-100 million of 10-year debt securities convertible into JTS Common Stock,
although the terms of such financing have not been established and the marketing
effort for such financing has not yet commenced. Recent comparable transactions
were priced to yield between 5.5-6.5% annually and included conversion premiums
over the market prices of the Common Stock of between 20-25%. JTS intends for
such financing to close as soon as practicable after the closing of the Merger,
and the terms of the debt securities and the amount of the
 
                                       18
<PAGE>   23
 
securities offered will not be determined until the closing of the financing, if
any. There can be no assurance that JTS will be able to consummate such
financing on terms acceptable to JTS or at all. As a result, the pro forma
financial statements included in this Joint Proxy Statement/Prospectus do not
reflect such transactions. The issuance of equity or convertible debt
securities, upon conversion, would result in dilution of the voting control of
existing stockholders, could result in dilution to earnings per share and would
provide to the holders of convertible debt securities seniority over the holders
of JTS Common Stock issued in the Merger. There can be no assurance that
additional funding will be available on terms acceptable to JTS or at all. The
failure to fund its capital requirements with additional financing would have a
material adverse effect on JTS' business, operating results and financial
condition. Furthermore, certain equipment and receivables financing as well as
term loans made to JTS and Moduler Electronics are contingent on JTS' ability to
comply with stringent financial covenants. In this regard, Moduler Electronics
did not obtain certain debt and equity capital required under one of its loan
agreements. JTS has informed the lender that it intends to provide such capital
by August 1996. In addition, certain of Moduler Electronics' loan agreements
require the lender's consent to mergers and similar transactions, which could be
interpreted to require the consent of the lending institution to the acquisition
of 90% of the capital stock of Moduler Electronics by JTS. Such consents were
not obtained, but the lending institution has continued to transact business
with Moduler Electronics and JTS since JTS' share acquisition in Moduler
Electronics. JTS believes that such matters regarding the Moduler Electronics
loan agreements will not have a material adverse effect on JTS' business,
operating results or financial condition. There can be no assurance that JTS
will be able to maintain its current financing facilities or obtain additional
financing as needed on acceptable terms or at all. If JTS is unable to obtain
sufficient capital, it would be required to curtail its facilities expansion,
capital expenditures, working capital, research and development and vendor
tooling expenditures, which would materially adversely affect JTS' business,
operating results and financial condition. See "Information Regarding JTS
Corporation -- Management's Discussion and Analysis of Financial Condition and
Results of Operations of JTS -- Liquidity and Capital Resources."
 
     Uncertainty of Market Acceptance; Lengthy Sales Cycle.  Since its inception
in February 1994, JTS has primarily engaged in research and development of its
core technology for hard disk drives. JTS' marketing strategy depends
significantly on its ability to establish distribution, licensing, product
development and other strategic relationships with major computer OEMs and on
the willingness and ability of these companies to utilize and to promote JTS'
hard disk drive technology and products. JTS' first commercial product line, the
Palladium family of hard disk drives, was introduced in September 1995 and is
targeted at the desktop personal computer market. JTS' second product line, the
Nordic family of hard disk drives, has been designed for notebook computers. See
"Information Regarding JTS Corporation -- Business of JTS -- Products." There
can be no assurance that any significant market for either product family will
develop. In particular, the Nordic drives use a 3-inch form factor, which JTS
has only recently introduced to the industry. At present, only a limited number
of computer manufacturers are developing or have plans to develop computers that
may accommodate Nordic drives. If additional computer manufacturers do not
modify their existing products or develop new products to accommodate 3-inch
form factor disk drives, sales of Nordic disk drives and, hence, JTS' business,
operating results and financial condition would be materially adversely
affected.
 
     Qualifying hard disk drives for incorporation into a new computer product
requires JTS to work extensively with the customer and the customer's other
suppliers to meet product specifications. Customers often require a significant
number of product presentations and demonstrations, as well as substantial
interaction with JTS' senior management, before making a purchasing decision.
Accordingly, JTS' products typically have a lengthy sales cycle during which JTS
may expend substantial financial resources and management time and effort with
no assurance that a sale will result.
 
     Highly Competitive Market.  The hard disk drive industry is intensely
competitive and dominated by a small number of large companies, including
Quantum Corporation ("Quantum"), Seagate Technology, Inc. ("Seagate"), Western
Digital Corporation ("Western Digital") and Maxtor Corporation ("Maxtor"). In
addition, a number of computer companies, such as Hewlett-Packard Co.
("Hewlett-Packard"), International Business Machines, Inc. ("IBM") and Toshiba
Corporation ("Toshiba"), have in-house or "captive" disk drive manufacturing
operations that produce disk drives for incorporation into their own computers
as well as
 
                                       19
<PAGE>   24
 
for sale to other OEMs. Many of JTS' competitors have broader product lines than
JTS, and all have significantly greater financial, technical and marketing
resources. Furthermore, JTS has licensed key 3-inch form factor technology to
Western Digital, a potential competitor in the personal computer disk drive
market that could become a significant supplier of 3-inch form factor disk
drives to Compaq and other OEMs. See "Information Regarding JTS
Corporation -- Business of JTS -- Western Digital Arrangement." There can be no
assurance that JTS will develop and manufacture products on a timely basis with
the quality and features necessary to compete effectively. High volume hard disk
drive users typically will only utilize from two to four suppliers. As a result,
it may be necessary for JTS to displace competitors in many circumstances to
increase its net sales. In addition, JTS faces competition from the
manufacturing operations of its current and potential OEM customers, which could
initiate or increase internal production of hard disk drives and reduce or cease
purchasing from independent hard disk drive suppliers such as JTS. Moreover, the
hard disk drive industry is characterized by price erosion and resulting
pressure on gross margins. JTS expects that hard disk drive prices will continue
to decline in the future and that competitors will offer products which meet or
exceed the performance capabilities of JTS products. Due to such pricing
pressures, JTS' future gross margins will be substantially dependent upon its
ability to control manufacturing costs, improve manufacturing yields and
introduce new products on a timely basis. Any increase in price competition
would have a material adverse effect on JTS' business, operating results and
financial condition. JTS may also experience competition from other forms of
data storage, including optical storage, flash memory and holographic storage.
If JTS' current and prospective customers and end users were to adopt such data
storage products as an alternative to JTS' products, JTS' business, operating
results and financial condition would be adversely affected. See "Information
Regarding JTS Corporation -- Business of JTS -- Competition."
 
     Rapid Technological Change; Short Product Life Cycles; Price Erosion.  The
hard disk drive industry is characterized by rapid technological change, short
product life cycles and price erosion. As a result, JTS must continually
anticipate change and adapt its products to meet demand for increased storage
capacity. Although JTS intends to engage in a continuous process of developing
new products and production techniques, there can be no assurance that JTS will
anticipate advances in hard disk drive technology and develop products
incorporating such advances in a timely manner to compete effectively against
its competitors' new products. Due to the rapid technological change and
frequent development of new hard disk drive products, it is common in the
industry for the relative mix of customers and products to change rapidly, even
from quarter to quarter. For example, in the first half of 1996, the demand for
1 gigabyte 3.5-inch form factor hard disk drives decreased dramatically due to
increased availability of and demand for larger capacity disk drives. As a
result, pricing pressure on such disk drives, including those marketed by JTS,
increased and gross margins decreased. Generally, new products have higher
average selling prices than more mature products. Therefore, JTS' ability to
introduce new products in a timely fashion is an important factor in achieving
growth and profitability. In addition, JTS anticipates continued changes in the
requirements of its customers in the computer industry. There can be no
assurance that JTS will be able to develop, manufacture and sell products that
respond adequately to such changes or that future technological innovations will
not reduce demand for hard disk drives. JTS' business, operating results and
financial condition would be materially adversely affected if its development
efforts are not successful, if the technologies that JTS has chosen not to
develop prove to be competitive alternatives or by trends toward technology that
would replace hard disk drives as a storage medium, such as optical storage,
flash memory and holographic storage. As JTS increases its production and
shipment of hard disk drives and expands its product line, JTS' inventory levels
will increase. Due to the rapid rate of change in JTS' business, a large
inventory poses the risk of inventory obsolescence which could have an adverse
effect on JTS' business, operating results and financial condition. In this
regard, JTS anticipates incurring future inventory allowances, the level of
which will depend upon a number of factors, including manufacturing yields, new
product introductions, maturity or obsolescence of product designs, inventory
levels and competitive pressures.
 
     Recent Significant Appreciation in Price of Atari Common Stock.  The
closing price per share of Atari Common Stock was $1.875 at February 12, 1996,
the last day of trading before announcement of the agreement between JTS and
Atari to merge the two companies. The price of Atari Common Stock has
appreciated significantly since then, notwithstanding the absence of any
significant publicly available information regarding the financial results or
business operations of JTS or the Combined Company and the absence of any
material positive developments in the financial results or business operations
of Atari. See
 
                                       20
<PAGE>   25
 
"Price Range of Common Stock." There can be no assurance that the recent price
appreciation of Atari Common Stock is indicative of the price that will prevail
for the JTS Common Stock following completion of the Merger.
 
     Availability of Components and Materials; Dependence on Suppliers.  JTS
relies on a limited number of suppliers for many components and materials used
in its manufacturing processes, including recording disks, head stack components
and integrated circuits. At present, JTS does not have multiple suppliers for
all of its materials and component requirements, and there can be no assurance
that JTS will secure more than one source for all of its requirements in the
future or that its suppliers will be able to meet its requirements on a timely
basis or on acceptable terms. Furthermore, JTS does not have contractual
arrangements with any of its sole source suppliers. In particular, JTS presently
relies on sole source suppliers for controller application specific integrated
circuits ("ASICs"), spindle motors, certain head stack components and disk
media. Delays in the receipt of certain components and materials have occurred
in the past, and there can be no assurance that delays will not occur in the
future or that suppliers will not extend lead times. Moreover, changing
suppliers for certain materials, such as spindle motors, could require
requalification of JTS' products with some or all of its customers.
Requalification could prevent early design-in wins or could prevent or delay
continued participation in hard disk drive programs for which JTS' products have
been qualified. In addition, long lead times are required to obtain many
materials, such as integrated circuits utilized in JTS' printed circuit board
assemblies ("PCBAs"). Regardless of whether these materials are available from
established or new sources of supply, these lead times could impede JTS' ability
to quickly respond to changes in demand and product requirements. Any
limitations on, or delays in, the supply of materials could disrupt JTS'
production volume and could have a material adverse effect on JTS' business,
operating results and financial condition. In this regard, in the fourth quarter
of fiscal 1996, JTS experienced delays in obtaining certain integrated circuits
required in the assembly of PCBAs due to the supplier's production problems,
which resulted in a significant reduction in production volume during such
period. Such production problems were corrected, but there can be no assurance
that production problems of this type or otherwise will not occur again in the
future. Furthermore, a significant increase in the price of one or more of these
components or materials could adversely affect JTS' business, operating results
and financial condition. In addition, there are only a limited number of
providers of hard disk drive manufacturing equipment, such as servo-writers,
burn-in equipment and final test equipment, and ordering additional equipment
for replacement or expansion involves long lead times, which limit the rate and
flexibility of capacity expansion. Failure to obtain such manufacturing
equipment on a timely basis could limit JTS' production of hard disk drives and
adversely affect JTS' business, operating results and financial condition. See
"Information Regarding JTS Corporation -- Business of JTS -- Manufacturing."
 
     Cyclical Nature of Hard Disk Drive and Computer Industries.  JTS' operating
results are dependent on the demand for hard disk drives, which in turn depends
on the demand for notebook and desktop personal computers. The hard disk drive
industry is cyclical and has experienced periods of oversupply, resulting in
significantly reduced demand for hard disk drives, as well as pricing pressures
and reduced production levels. The effect of these cycles has been magnified by
computer manufacturers' practice of ordering components, including hard disk
drives, in excess of their needs during periods of rapid growth. In recent
years, the disk drive industry has experienced significant growth, and JTS
intends to expand its capacity based on current and anticipated demand. There
can be no assurance that such growth will continue or that the level of demand
will not decline. A decline in demand for hard disk drives would have a material
adverse effect on JTS' business, operating results and financial condition.
Additionally, in the past some computer manufacturers have experienced
substantial financial difficulties due to the cyclical nature of the computer
industry and other factors. In this regard, certain personal computer
manufacturers have recently announced reductions in anticipated revenue growth.
Any increased price pressure in the personal computer industry could be passed
through to personal computer component suppliers, including manufacturers of
hard disk drives.To date, JTS has not incurred significant bad debt expense.
However, there can be no assurance that JTS will not face difficulty in
collecting receivables or be required to offer more liberal payment terms in the
future, particularly in a period of reduced demand. Any failure to collect or
delay in collecting receivables could have a material adverse effect on JTS'
business, operating results and financial condition.

<PAGE>   26
 
     Dependence on Compaq Computer Relationship; Customer Concentration.  JTS'
strategy to commercialize its products and achieve market acceptance has focused
in large part on the development of distribution, licensing, product development
and other strategic relationships with leading computer companies, other
manufacturers of computer peripherals and recognized distribution organizations.
Through these relationships, JTS seeks to establish its products and
technologies as industry standards. In this regard, JTS has entered into a
Development Agreement with Compaq Computer Corporation ("Compaq") pursuant to
which Compaq has agreed to design JTS' Nordic disk drives into at least one of
Compaq's products and to purchase a minimum number of hard disk drives from JTS
within two years following Compaq's acceptance of the first of such products. In
return, JTS has granted to Compaq certain pricing preferences and agreed to pay
royalties to Compaq on the sales of Nordic disk drives to third parties during
the term of the agreement. Compaq has also been granted a license to use the
Nordic designs to manufacture Nordic drives on a royalty-free basis in the event
that JTS fails to meet the agreed upon production schedule. The Development
Agreement also restricts JTS' ability to sublicense Nordic technology. The
Development Agreement has a five year term, which will automatically be renewed
under certain circumstances and may be terminated by either party only with
cause. In order to provide a second source of JTS' products, JTS has entered
into a Technology Transfer and License Agreement with Western Digital pursuant
to which Western Digital has the right to manufacture and sell Nordic disk
drives to Compaq. If either of these agreements were to terminate prematurely,
JTS' efforts to establish market acceptance of its products and, consequently
its business, operating results and financial condition would be adversely
affected. See "Information Regarding JTS Corporation -- Business of JTS --
Relationship With Compaq" and "-- Western Digital Arrangement." In fiscal 1996,
Olidata S.p.A, Connexe Peripherals, Ltd., Liuski International, Inc. and Aashima
Technology, B.V. accounted for 34%, 12%, 11% and 10%, respectively, of JTS'
total revenue. In the quarter ended April 28, 1996, Peacock Systems GmbH,
Markvision International S.A. and FutureTech accounted for 43%, 18% and 14%,
respectively, of JTS' total revenues. JTS expects that sales to a relatively
small number of OEMs will account for a substantial portion of its net revenues
for the foreseeable future, although the companies that comprise JTS' largest
customers may change from period to period. The loss of, or decline in orders
from, one or more of JTS' key customers would have a material adverse effect on
JTS' business, operating results and financial condition. See "Information
Regarding JTS Corporation -- Business of JTS -- Patents and Licenses."
 
     Reliance on Licensed Technology.  JTS currently owns no patents and has
obtained licenses to a substantial portion of the technology used in its hard
disk drives pursuant to license agreements with Pont Peripherals Corporation,
TEAC Corporation and Western Digital. If such license agreements were
prematurely terminated or if JTS were enjoined from relying upon such licenses
due to JTS' alleged or actual breach of such agreements, JTS would be prevented
from manufacturing hard disk drives incorporating technology subject to such
licenses. As a result, JTS' business, operating results and financial condition
would be materially adversely affected. See "Information Regarding JTS
Corporation -- Business of JTS -- Patents and Licenses."
 
     Intellectual Property and Proprietary Rights.  Although JTS attempts to
protect its intellectual property rights through patents, copyrights, trade
secrets and other measures, there can be no assurance that JTS will be able to
protect its technology adequately or that competitors will not be able to
develop similar technology independently. There can be no assurance that patents
will be issued with respect to JTS' pending patent applications or that any
future patents will be sufficiently broad to protect JTS' technology. There can
be no assurance that any future patent issued to JTS will not be challenged,
invalidated or circumvented or that the rights granted thereunder will provide
adequate protection to JTS' products. Furthermore, there can be no assurance
that others will not independently develop similar products, duplicate JTS'
products or design around any possible patents issued to JTS in the future. In
addition, the laws of certain foreign countries may not protect JTS'
intellectual property rights to the same extent as do the laws of the United
States.
 
     In recent years, the hard disk drive industry has experienced an increase
in litigation to enforce intellectual property rights. Thus, litigation may be
necessary to enforce any future JTS patents, copyrights or other intellectual
property rights, to protect JTS' trade secrets, to determine the validity and
scope of the proprietary rights of others, or to defend against claims of
infringement or claims for indemnification resulting from infringement claims.
Such litigation, even if successful, could result in substantial costs and
diversion of resources and could have a material adverse effect on JTS'
business, operating results and financial condition.

Alternatively, if any claims are asserted against JTS, JTS may seek to obtain a
license under the third party's intellectual property rights or to seek to
design around such claims. There can be no assurance, however, that a license
will be available on reasonable terms or at all, and it could be expensive and
time consuming or prove impossible for JTS to design around such claims. Any of
such alternatives could materially and adversely affect JTS' business, results
of operations and financial condition.
 
     Expansion of Manufacturing Capacity.  JTS' competitive position will depend
substantially on its ability to expand its manufacturing capacity. Accordingly,
JTS is continuing to make significant investments to expand such capacity,
particularly through the acquisition of capital equipment, facilities expansion
and the hiring and training of new personnel. JTS currently plans to add new
production lines at its existing manufacturing facility in Madras, India during
fiscal 1997 that will utilize all available floor space at this facility. There
can be no assurance that JTS will be able to expand such capacity in a timely
manner, that the cost of such expansion will not exceed management's current
estimates, that such capacity will not exceed the demand for JTS products or
that such additional capacity will achieve satisfactory levels of manufacturing
efficiency in a timely manner or at all. In addition, the expansion of
manufacturing capacity will significantly increase JTS' fixed costs. JTS'
profitability will depend on its ability to utilize its manufacturing capacity
in an effective manner, and JTS' inability to fully utilize its capacity would
have a material adverse effect on JTS' business, operating results and financial
condition. See "Information Regarding JTS Corporation -- Business of JTS --
Manufacturing."
 
     Dependence on Single Manufacturing Facility.  In fiscal 1996, substantially
all of JTS' manufacturing operations took place at Moduler Electronics in
Madras, India. Because JTS does not currently operate multiple facilities in
different geographic areas, a disruption of JTS' manufacturing operations
resulting from various factors, including sustained process abnormalities, human
error, government interventions or a natural disaster such as fire or flood,
could cause JTS to cease or limit its manufacturing operations and consequently
would have a material adverse effect on JTS' business, operating results and
financial condition.
 
     Risks of International Sales and Manufacturing.  In fiscal 1996 and the
three months ended April 30, 1996, substantially all of JTS' net sales consisted
of products sold to customers in Europe, Asia and Latin America, and JTS
anticipates that a substantial percentage of its products will be sold to
customers outside of the United States for the foreseeable future. Furthermore,
JTS expects to conduct substantially all of its manufacturing operations in
India, although JTS may evaluate alternative or additional locations from time
to time. Accordingly, JTS' operating results are subject to the risks of doing
business in a foreign country, including compliance with, or changes in, the law
and regulatory requirements of a foreign country, political instability, local
content rules, taxes, tariffs or other barriers, and transportation delays and
other interruptions. For example, the Indian government has granted JTS a five
year "tax holiday," and its subsidiary, Moduler Electronics, is located in the
Madras Export Processing Zone where it currently enjoys an exemption from Indian
taxes on export profits, although to date JTS has retained only minimal benefits
from such exemption. Such exemption may be terminated at any time for political
or economic reasons, in which event JTS may become subject to significantly
greater taxes on sales of disk drives outside of India at rates currently of up
to 46%. Furthermore, JTS does not have a long-term lease agreement, but rather
occupies the Madras facility pursuant to allotment letters from the Development
Commissioner of the Madras Export Processing Zone. Other benefits associated
with conducting business in India, which historically has experienced
considerable political instability, are subject to the vagaries of the Indian
government and may be withdrawn at any time. Although all of JTS' sales
presently are made in U.S. dollars, there can be no assurance that future
international sales will not be denominated in foreign currencies. Regardless of
whether JTS' sales are denominated in foreign currencies, JTS is, and will
continue to be, subject to risks related to foreign currency fluctuations.
 
     Production Yields; Product Quality.  The hard disk drive manufacturing
process is complex, and low production yields may result from a variety of
factors, including the introduction of new products, increased complexity in
product specifications, human error, the introduction of contaminants in the
manufacturing environment, equipment malfunction, use of defective materials and
components and inadequate testing. From time to time, JTS has experienced lower
than anticipated production yields as a result of such factors. Furthermore,
while JTS has implemented procedures to monitor the quality of the materials
received from its suppliers, there can be no assurance that materials will meet
JTS' specifications or that substandard materials will not adversely impact
production yields or cause other production problems. JTS' failure to maintain
high quality production standards or acceptable production yields would result
in loss of customers, delays in
 
                                       23
<PAGE>   28
 
shipments, increased costs, cancellation of orders and product returns for
rework, any of which could have a material adverse effect on JTS' business,
operating results and financial condition. For example, JTS' cost of sales for
fiscal 1996 included a $4.3 million provision for inventory allowances
principally due to the costs for return of defective products, scrapped material
associated with unrepairable damage caused during the assembly process and
estimates of physical loss of inventory associated with high volume
manufacturing activities.
 
     Variability of Operating Results.  JTS' operating results are expected to
be subject to significant quarterly and annual fluctuations based upon a variety
of factors including market acceptance of JTS' products, timing of significant
orders, changes in pricing by JTS or its competitors, the timing of product
announcements by JTS, its customers or its competitors, changes in product mix,
manufacturing yields, order cancellations, modifications and quantity
adjustments and shipment reschedulings, the level of utilization of JTS'
production capacity, increases in production and engineering costs associated
with initial manufacture of new products, changes in the cost of or limitations
on availability of components and materials and customer returns. The impact of
these and other factors on JTS' revenues and operating results in any future
period cannot be predicted with certainty. JTS' expense levels are based, in
large part, on its expectations as to future revenues. Substantial advance
planning and commitment of financial and other resources is necessary for
expansion of manufacturing capacity, while JTS' sales are generally made
pursuant to purchase orders that are subject to cancellation, modification,
quantity reductions or rescheduling without significant penalties. Furthermore,
because the hard disk drive industry is capital intensive and requires a high
level of fixed costs, operating results are extremely sensitive to changes in
volume. Accordingly, if revenue levels do not meet expectations, operating
results and net income, if any, are likely to be adversely affected. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations of JTS."
 
     Management of Growth.  JTS has recently experienced and may continue to
experience substantial growth in the number of its employees and the scope of
its operations. Such growth would further strain JTS' managerial, financial,
manufacturing and other resources. In addition, in order to manage its growth
effectively, JTS must implement additional operating, financial and management
information systems and hire and train additional personnel. In particular, JTS
must hire and train a significant number of additional personnel to operate the
highly complex capital equipment required by its manufacturing operations. There
can be no assurance that JTS will successfully implement additional systems in a
timely or efficient manner, to hire and properly train a sufficient number of
qualified personnel or to effectively manage such growth, and JTS' failure to do
so could have a material adverse effect on its business, operating results and
financial condition. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations of JTS" and "Information Regarding JTS
Corporation -- Business of JTS -- Employees."
 
     Dependence on Key Management Personnel.  JTS' operating results will depend
in significant part upon the continued contributions of its key management and
technical personnel, including Sirjang L. Tandon, its Chairman and Corporate
Technical Strategist, David T. Mitchell, its President and Chief Executive
Officer, Kenneth D. Wing, its Executive Vice President, Research and Development
Quality/Reliability, W. Virginia Walker, its Executive Vice President, Finance
and Administration, Chief Financial Officer and Secretary, and Steven L.
Kaczeus, its Chief Technical Officer, each of whom would be difficult to
replace. See "Information Regarding JTS Corporation -- Management of JTS." JTS
does not have an employment agreement with any of these individuals. The loss of
any of these key personnel could have a material adverse effect on the business,
operating results and financial condition of JTS. In addition, JTS' future
operating results depend in part upon its ability to attract, train, retain and
motivate other qualified management, technical, manufacturing, sales and support
personnel for its operations. Competition for such personnel is intense, and
there can be no assurance that JTS will be successful in attracting or retaining
such personnel. The loss of the services of existing personnel as well as the
failure to recruit additional personnel could materially adversely affect JTS'
business, operating results and financial condition. See "Information Regarding
JTS Corporation -- Business of JTS -- Employees."
 
     Purchase Orders Subject to Cancellation, Modification and
Rescheduling.  JTS' sales are generally made pursuant to purchase orders that
are subject to cancellation, modification, quantity reductions or rescheduling
without significant penalties. Changes in forecasts, cancellations, rescheduling
and quantity reductions may result in excess inventory costs, inventory losses
and under-utilization of production capacity and could have a
 
                                       24
<PAGE>   29
 
material adverse effect on JTS' business, operating results and financial
condition. As a result of the foregoing, JTS' backlog as of any particular date
may not be representative of actual sales for any succeeding period.
 
     Reduction in Voting Control.  Upon the closing of the Merger, the Atari
stockholders immediately prior to the Merger will own approximately 62% of the
outstanding voting securities of the Combined Company (assuming no exercise of
options after June 28, 1996). As a result, such stockholders, acting together,
could determine the outcome of matters requiring approval of the stockholders of
the Combined Company. Such matters include the election of the members of the
Combined Company's Board of Directors, proxy contests, mergers involving the
Combined Company, tender offers or other transactions that could afford
stockholders of the Combined Company the opportunity to realize a premium over
the then prevailing market price of the Common Stock of the Combined Company.
Furthermore, following the Merger, members of the Tramiel family will own
approximately 27% of the outstanding voting securities of the Combined Company
(assuming no exercise of options after June 28, 1996). Jack Tramiel will also be
a member of the Combined Company's Board of Directors. As a result, the members
of the Tramiel family, acting together, could exert significant influence over
matters requiring approval of the stockholders of the Combined Company.
 
OTHER RISK FACTORS RELATED TO THE MERGER
 
     Risks Associated with Fixed Exchange Ratio.  All of the material terms of
the Merger, including the one-for-one exchange ratio, were agreed upon when the
initial merger agreement was signed on February 12, 1996. Although the structure
of the transaction was modified as reflected in the Merger Agreement which was
signed on April 8, 1996, such change did not materially modify the economic
terms of the Merger. Since February 12, 1996, there have been ongoing business
developments that have necessarily impacted Atari and JTS. With respect to
Atari, these developments include continued significant operating losses and
decreases in revenues, continued intense competition in the video game industry
and a significant increase in the trading price for the Atari Common Stock. With
respect to JTS, these developments include continued losses, delays in the
schedule for volume shipments of Nordic disk drives, reductions in the targeted
revenues, gross profit and net income for fiscal 1997, JTS' decision to pursue
additional financing as soon as practicable following the Merger and the fact
that Compaq has accepted the JTS Nordic 3-inch disk drive. Notwithstanding these
factors, there is no provision in the Merger Agreement for adjustment prior to
the closing of the Merger of the rate at which the Atari Common Stock will be
exchanged for JTS Common Stock.
 
   
     Significant Lapse of Time Since Delivery of Montgomery Fairness
Opinion.  The opinion of Montgomery Securities that the conversion ratio of
Atari Common Stock into JTS Common Stock was fair to Atari, from a financial
point of view, was delivered to the Atari Board of Directors on February 5, 1996
and is applicable only as of such date. The Atari Board of Directors evaluated
the recent business developments of Atari and JTS at its meeting on June 21,
1996 and unanimously affirmed its approval of the Merger. At this meeting, the
Atari Board of Directors also determined not to obtain an updated fairness
opinion from Montgomery with respect to the Merger. As a result of significant
changes in the business of JTS since the date of Montgomery's fairness opinion,
Atari stockholders should not place undue reliance upon the availability of such
opinion.
    
 
     Utilization of Net Operating Losses.  As of December 31, 1995, Atari had
federal net operating losses ("NOLs") and tax credit carryforwards in the amount
of approximately $166.8 million, and as of January 28, 1996, JTS had federal
NOLs of approximately $27.0 million. Under the Internal Revenue Code of 1986, as
amended (the "Code"), certain changes in the ownership or business of a
corporation that has NOLs or tax credit carryforwards will result in the
inability to use or the imposition of significant restrictions on the use of
such NOLs or tax credit carryforwards to offset future income and tax liability
of such corporation, its subsidiaries or its successors. The Merger will
constitute a change in ownership with respect to JTS, and the Merger or
subsequent events may constitute an event with respect to Atari which results in
the imposition of restrictions on the ability of the Combined Company to utilize
NOLs and tax credit carryforwards of Atari or JTS. There can be no assurance
that the Combined Company will be able to utilize all or any NOLs or tax credit
carryforwards of Atari or JTS. The ability of the Combined Company to utilize
Atari's accumulated NOLs and tax carryforwards was a factor considered by the
boards of directors of Atari and JTS in concluding to approve the Merger and the
Merger Agreement and to recommend that the stockholders of Atari and JTS approve
the Merger and the Merger Agreement. See "The Proposed Merger and Related
Transactions --

Background and Board Recommendations -- Recommendation of the Board of Directors
of Atari" and "--Recommendation of the Board of Directors of JTS."
 
     Control by Affiliates; Anti-takeover Effects.  Upon completion of the
Merger, directors, officers and holders of 10% or more of the outstanding JTS
Common Stock will own approximately 35% of the outstanding shares of the
Combined Company (assuming no exercise of options or warrants after June 28,
1996). As a result, these affiliates of the Combined Company, acting together,
will have the ability to exert significant influence over the election of
directors and other corporate actions affecting the Combined Company. Certain
provisions of the Certificate of Incorporation and Bylaws of the Combined
Company and certain provisions of the DGCL, including Section 203 thereof, may
also discourage certain transactions involving a change in control of the
Combined Company. In addition to the foregoing, the ability of the Board of
Directors of the Combined Company to issue additional "blank check" preferred
stock without further stockholder approval could have the effect of delaying,
deferring or preventing a change in control of the Combined Company. See
"Information Regarding Atari Corporation -- Principal Stockholders of Atari,"
"Information Regarding JTS Corporation -- Principal Stockholders of JTS" and
"Description of Capital Stock of Atari and JTS."
 
     Shares Eligible for Future Sale.  Sales of substantial amounts of JTS
Common Stock in the public market after the consummation of the Merger could
adversely affect prevailing market prices. Following the Merger, the Combined
Company will have approximately 102,814,954 shares of Common Stock outstanding
(assuming no exercise of options or warrants after June 28, 1996). All of the
63,854,718 shares of JTS Common Stock to be issued to the former stockholders of
Atari in the Merger will be eligible for sale in the public market upon the
closing of the Merger. Of such shares, approximately 23,950,000 shares held by
affiliates of Atari will be subject to volume and other restrictions under Rule
145 of the Securities Act. In addition, 90 days following the consummation of
the Merger, approximately 3,900,000 shares of JTS Common Stock will become
eligible for sale in the public market pursuant to Rule 701 under the Securities
Act. In addition, in February and August 1997, approximately 16,200,000 shares
and 12,500,000 shares of JTS Common Stock, respectively, will become eligible
for sale in the public market pursuant to Rule 144 of the Securities Act upon
expiration of the two-year holding periods from the dates such shares were
issued.
 
     In addition, the holders of approximately 42,500,000 shares of JTS Common
Stock outstanding as of the closing of the Merger will be entitled to certain
rights with respect to registration of such shares under the Securities Act. JTS
also intends to register for sale on a Form S-8 Registration Statement under the
Securities Act an aggregate of approximately 8,985,000 shares of JTS Common
Stock reserved for issuance under JTS' Restated Plan, 500,000 shares of JTS
Common Stock reserved for issuance under JTS' Non-Employee Directors' Plan, and
approximately 900,000 shares of JTS Common Stock reserved for issuance pursuant
to the exercise of options granted under Atari's 1986 Stock Option Plan which
will be assumed by JTS in the Merger. Former stockholders of JTS have not
previously had the opportunity to sell their shares in the public market.
Substantial sales of JTS Common Stock after the Merger could have a negative
impact on the market price and liquidity of the JTS Common Stock.
 
     Diversion of Management Attention.  Following the Merger, Atari and JTS
will operate as separate divisions of the Combined Company and the current
management of JTS will serve as the management of the Combined Company. The
Combined Company's management is expected to devote substantially all of its
time to the affairs of JTS following the Merger. If the management of the
Combined Company were unable to effectively manage the separate businesses, the
operating results and financial condition of the Combined Company could be
materially adversely affected.
 
     No Prior Market; Liquidity; Stock Price Volatility.  Prior to the Merger
there was no public market for JTS' capital stock. Although it is expected that
the JTS Common Stock will be listed on the American Stock Exchange upon the
closing of the Merger, there can be no assurance that an active public market
for the JTS Common Stock will develop or be sustained. The trading price of the
JTS Common Stock could be subject to wide fluctuations in response to
quarter-to-quarter variations in operating results, announcements of
technological innovations or new products by JTS or its competitors, general
conditions in the hard disk drive, computer or video game industries, changes in
earnings estimates or recommendations by analysts, or other events or factors.
In addition, the public stock markets have experienced extreme price and trading
volume volatility in recent months. This volatility has significantly affected
the market prices of securities of many technology companies for reasons
frequently unrelated to the operating performance of the specific companies.
These broad market fluctuations may adversely affect the market price of the JTS
Common Stock.

                                  INTRODUCTION
 
     This Joint Proxy Statement/Prospectus is furnished in connection with the
solicitation by Atari and JTS of proxies to be voted at the Atari Special
Meeting and the JTS Special Meeting, respectively. This Joint Proxy
Statement/Prospectus is being mailed to stockholders of Atari and JTS on or
about July 15, 1996.
 
     The purpose of the Atari and JTS Special Meetings is to consider and vote
upon a proposal to approve the Merger and the Merger Agreement. Upon
consummation of the Merger, Atari will be merged with and into JTS, the separate
existence of Atari will cease, JTS will remain as the surviving corporation and
all of the rights, privileges, powers, franchises, properties, assets,
liabilities and obligations of Atari will be vested in JTS. At the Effective
Time (as such term is defined below), each outstanding share of Atari Common
Stock will be converted into one share of JTS Common Stock and each outstanding
option to purchase Atari Common Stock will become an option to purchase JTS
Common Stock.
 
     Based on the number of shares of outstanding Atari Common Stock, JTS Common
Stock and JTS Series A Preferred Stock as of June 28, 1996 (assuming no exercise
of outstanding options after such date), immediately after consummation of the
Merger (assuming the conversion of all outstanding shares of JTS Series A
Preferred Stock into shares of JTS Common Stock and that none of the holders of
JTS Common Stock or JTS Series A Preferred Stock perfects appraisal or
dissenters' rights), a total of 102,814,954 shares of JTS Common Stock would be
issued and outstanding, of which 63,854,718 shares, or 62%, would represent
shares issued in the Merger upon conversion of Atari Common Stock.
 
     THE BOARDS OF DIRECTORS OF EACH OF ATARI AND JTS HAVE UNANIMOUSLY
DETERMINED THAT THE MERGER AND THE MERGER AGREEMENT ARE FAIR TO, AND IN THE BEST
INTERESTS OF, ITS RESPECTIVE CORPORATION AND ITS RESPECTIVE STOCKHOLDERS.
 
     THE BOARDS OF DIRECTORS OF EACH OF ATARI AND JTS UNANIMOUSLY RECOMMEND THAT
THE STOCKHOLDERS OF ITS RESPECTIVE CORPORATION APPROVE THE MERGER AND THE MERGER
AGREEMENT.
 
     This Joint Proxy Statement/Prospectus also constitutes the prospectus of
JTS under the Securities Act for the offering of JTS Common Stock in connection
with the Merger. This Joint Proxy Statement/Prospectus does not cover resales of
the securities of JTS to be received in connection with the Merger and no person
is authorized to use this prospectus in connection with any resale.
 
     The principal offices of Atari are located at 455 South Mathilda Avenue,
Sunnyvale, California 94086, and its telephone number is (408) 328-0900. The

                               VOTING AND PROXIES
 
DATE, TIME AND PLACE OF SPECIAL STOCKHOLDER MEETINGS
 
     Atari.  The Atari Special Meeting will be held at the offices of Wilson
Sonsini Goodrich & Rosati, P.C., 650 Page Mill Road, Palo Alto, California,
legal counsel to Atari, on July 30, 1996 at 9:00 a.m.
 
     JTS.  The JTS Special Meeting will be held at JTS's offices at 166
Baypointe Parkway, San Jose, California 95134, on July 30, 1996 at 9:00 a.m.
 
RECORD DATE AND OUTSTANDING SHARES
 
     Atari.  Stockholders of record of Atari Common Stock at the close of
business on June 28, 1996 (the "Atari Record Date") are entitled to notice of
and to vote at the Atari Special Meeting. At the Atari Record Date, there were
approximately 2,375 holders of record of Atari Common Stock and 63,854,718
shares of Atari Common Stock were issued and outstanding. Except for the
stockholders identified below under "Information Regarding Atari Corporation --
Principal Stockholders of Atari," there were no persons known to the management
of Atari to be the beneficial owners of more than 5% of the outstanding shares
of Atari Common Stock.
 
     JTS.  Stockholders of record of JTS Common Stock and JTS Series A Preferred
Stock at the close of business on June 18, 1996 (the "JTS Record Date") are
entitled to notice of and to vote at the JTS Special Meeting. At the JTS Record
Date, there were 20 holders of record of JTS Common Stock and 54 holders of
record of JTS Series A Preferred Stock and 9,263,866 shares of JTS Common Stock
and 29,696,370 shares of JTS Series A Preferred Stock were issued and
outstanding. Except for the stockholders identified below under "Information
Regarding JTS Corporation -- Principal Stockholders of JTS," there were no
persons known to the management of JTS to be the beneficial owners of more than
5% of the outstanding shares of any class of JTS capital stock.
 
VOTING AND REVOCABILITY OF PROXIES
 
     All properly executed proxies that are not revoked will be voted at the
respective Atari and JTS Special Meetings and any postponement or adjournment
thereof, in accordance with the instructions contained therein. Proxies
containing no instructions regarding the proposals specified in the form of
proxy will be voted for approval of the Merger and the Merger Agreement at the
Atari and JTS Special Meetings, as the case may be. Each record holder of Atari
Common Stock as of the Atari Record Date is entitled to cast one vote per share,
exercisable in person or by properly executed proxy, on each matter properly
submitted for the vote of the stockholders at the Atari Special Meeting. Each
record holder of JTS Common Stock and JTS Series A Preferred Stock as of the JTS
Record Date is entitled to cast one vote per share, exercisable in person or by
properly executed proxy, on each matter properly submitted for the vote of the
stockholders at the JTS Special Meeting.
 
     If an executed proxy card is returned and a stockholder has abstained from
voting on any matter, the shares represented by such proxy will be considered
present at the applicable special meeting for purposes of determining a quorum
and for purposes of calculating the vote, but will not be considered to have
been voted in favor as to such matter. In the case of the Atari Special Meeting,
if an executed proxy is returned by a broker holding shares in street name which
indicates that the broker does not have discretionary authority as to certain
shares to vote on one or more matters, such shares will be considered
represented at the Atari Special Meeting for purposes of determining a quorum,
but will not be considered to be represented at the Atari Special Meeting for
purposes of calculating the vote with respect to such matter ("broker
non-votes"). Because approval of the Merger and the Merger Agreement requires,
in the case of Atari, the affirmative vote of a majority of the total number of
outstanding shares of Atari Common Stock entitled to vote at the Atari Special
Meeting, and in the case of JTS, the affirmative vote of a majority of the total
number of outstanding shares of JTS Common Stock and JTS Series A Preferred
Stock (voting together) and at least two thirds of the total number of
outstanding shares of JTS Series A Preferred Stock (voting as a separate class)
entitled to
 
                                       28
<PAGE>   33
 
vote at the JTS Special Meeting, abstentions and, in the case of Atari, broker
non-votes, will have the same effect as a vote against the proposal. If an
executed proxy card is returned and a stockholder has voted against the
proposal, the shares represented by such proxy will also be deemed to have voted
against a resolution to postpone or adjourn the meeting.
 
     The presence of a stockholder at the applicable special meeting for which
such stockholder has executed a proxy will not automatically revoke such
stockholder's proxy. A stockholder may, however, revoke a proxy at any time
prior to its exercise by filing a written notice of revocation with, or by
delivering a duly executed proxy bearing a later date to, the Corporate
Secretary at the address of the principal executive offices of the company to
which such proxy relates, or by attending the special meeting to which such
proxy relates and voting in person.
 
STOCKHOLDER VOTES REQUIRED
 
     Atari.  The presence, in person or by proxy, of a majority of the shares of
Atari Common Stock outstanding on the Atari Record Date is necessary to
constitute a quorum at the Atari Special Meeting. Approval of the Merger and the
Merger Agreement requires the affirmative vote of holders of a majority of the
shares of Atari Common Stock outstanding on the Atari Record Date.
 
     It is expected that all of the 23,453,129 shares of Atari Common Stock
(excluding shares subject to stock options) beneficially owned by directors and
executive officers of Atari and their affiliates at the Atari Record Date (37%
of the total number of outstanding shares of Atari Common Stock) will be voted
for approval of the Merger and the Merger Agreement. As of the Atari Record
Date, JTS and its directors and executive officers and their affiliates
beneficially owned no shares of Atari Common Stock (excluding shares of Atari
Common Stock subject to the Voting Agreements). See "Information Regarding Atari
- -- Principal Stockholders of Atari."
 
     JTS.  The presence, in person or by proxy, of a majority of the shares of
JTS Common Stock and JTS Series A Preferred Stock outstanding on the JTS Record
Date is necessary to constitute a quorum at the JTS Special Meeting. Approval of
the Merger and the Merger Agreement requires the affirmative vote of holders of
(a) a majority of the shares of JTS Common Stock and JTS Series A Preferred
Stock outstanding on the JTS Record Date, voting together, (b) a majority of the
shares of JTS Common Stock outstanding on the JTS Record Date, voting separately
as a class, and (c) at least two thirds of the shares of JTS Series A Preferred
Stock outstanding on the JTS Record Date, voting separately as a class.
 
   
     It is expected that all of the 9,318,020 shares of JTS Common Stock
(excluding shares subject to stock options) and 14,122,107 shares of JTS Series
A Preferred Stock beneficially owned by directors and executive officers of JTS
and their affiliates at the JTS Record Date (99% of the total number of
outstanding shares of JTS Common Stock and 48% of the total number of
outstanding shares of JTS Series A Preferred Stock) will be voted for approval
of the Merger and the Merger Agreement. As of the JTS Record Date, Atari and its

of Atari and JTS have agreed to vote all shares held by them in favor of the
Merger and the Merger Agreement. Specifically, holders of approximately 43% of
the shares of Atari Common Stock, 91% of the shares of JTS Common Stock and 70%
of the shares of JTS Series A Preferred Stock entitled to vote at the respective
stockholder meetings have entered into Voting Agreements and irrevocable

                  THE PROPOSED MERGER AND RELATED TRANSACTIONS
 
BACKGROUND AND BOARD RECOMMENDATIONS
 
BACKGROUND OF THE MERGER
 
     By the second half of 1995, Atari and its Board of Directors recognized
that despite the significant financial resources that had been devoted to the
Jaguar product, it was unlikely that Jaguar would ever become a broadly accepted
video game console or that Jaguar technology would be broadly adopted by
software title developers. As a result, at its meeting on October 13, 1995, the
Atari Board of Directors determined to substantially reduce the resources
devoted to the Jaguar and related products, and to change Atari's strategic
focus by devoting its resources to PC software publishing and strategic
opportunities. In particular, the Atari Board of Directors directed management
to focus on evaluating strategic opportunities for Atari including potential
investments and acquisitions.
 
     As part of Atari's efforts to pursue strategic opportunities, during the
fourth quarter of 1995, Atari management contacted various individuals and
investment advisors with respect to potential strategic investments or
acquisitions. These efforts resulted in Atari's evaluation of several strategic
opportunities, including a potential investment in or merger with an
entertainment software company, a video game software company, a computer video
game peripherals company and a potential investment or merger with JTS.
 
     Since its inception in February 1994, JTS has continually sought to
identify new sources of financing to support the expansion of its manufacturing
facilities, capital expenditures and research and development activities. In
late 1995, JTS recognized the need for a significant infusion of capital within
the next three to four months to fund the growth of JTS' operations.
Accordingly, at a meeting held on October 30, 1995, the JTS Board of Directors
instructed members of management to explore various financing sources, including
the private placement of equity securities to one or more institutional
investors.
 
     In early November 1995, Sam Tramiel contacted JTS to set up a meeting with
Sirjang L. "Jugi" Tandon, the Chairman of JTS, and David T. Mitchell, JTS'
President and Chief Executive Officer, to discuss possible strategic
opportunities between the companies. On November 16, 1995, Sam Tramiel and Mr.
Tandon met at the Las Vegas airport following the Comdex show. At the meeting,
Mr. Tandon stated that JTS was pursuing additional sources of financing, and Sam
Tramiel indicated that Atari was evaluating various strategic opportunities,
including potential investments and acquisitions. A follow-up meeting was
scheduled for early December to further discuss a possible investment in JTS by
Atari.
 
     At a meeting held on November 29, 1995, the JTS Board of Directors
instructed Messrs. Tandon and Mitchell to accelerate their efforts to identify
new sources of financing. In this regard, JTS initiated discussions with two
investment banks (one of which was Montgomery) in December 1995 to explore the
possibility of a private placement to institutional investors which would result
in a substantial infusion of capital to JTS.
 
     On December 14, 1995, Jack Tramiel and Sam Tramiel met with Messrs. Tandon
and Mitchell at JTS. At this meeting, the parties discussed a potential
investment by Atari in JTS and the possibility that Jack Tramiel would become a
director of JTS. Later that day, the Executive Committee of the Atari Board of
Directors (consisting of Jack Tramiel, Sam Tramiel and August J. Liguori) held a
special meeting to discuss the proposed transaction with JTS. At the meeting,
the Atari Executive Committee directed Mr. Liguori, Atari's former Chief
Financial Officer, to contact JTS to initiate due diligence.
 
     On December 22, 1995, Mr. Liguori met with Mr. Mitchell and W. Virginia
Walker, JTS' Chief Financial Officer, at JTS to conduct an initial due diligence
review of JTS' business and financial condition.
 
     On January 4, 1996, the Executive Committee of the Atari Board of Directors
held a special meeting to discuss Mr. Liguori's due diligence investigation of
JTS. At this meeting, the Atari Executive Committee authorized Jack Tramiel to
continue discussions with JTS regarding a potential investment or other
strategic business relationship between Atari and JTS and instructed Mr. Liguori
to continue due diligence activities. The Atari Executive Committee also
instructed Jack Tramiel to contact the other members of the Atari Board to
update them on the potential business opportunity involving JTS.

     On January 8, 1996, Jack Tramiel, Sam Tramiel and Mr. Mitchell met at Jack
Tramiel's home to further discuss a possible strategic transaction between Atari
and JTS. At this meeting, the parties considered a significant investment by
Atari in JTS and a merger of Atari and JTS. Mr. Mitchell indicated that JTS
would be interested in securing a bridge loan from Atari if a merger agreement
were signed. The parties also generally discussed that, if a merger were to
occur, the consideration would be common stock of the acquiring company and the
exchange ratio would be one-for-one.
 
     On January 9, 1996, the JTS Board of Directors held a telephonic meeting at
which a possible investment by or merger with Atari was discussed. At the
meeting, the merits of such a transaction, including the general terms of a
possible merger, were considered and the JTS Board instructed members of
management to initiate a due diligence review of Atari. In addition, the JTS
Board agreed to retain the law firm of Cooley Godward Castro Huddleson & Tatum
("Cooley Godward") to assist in the evaluation of a possible business
combination with Atari.
 
     On January 10, 1996, Mr. Mitchell and Ms. Walker met with Jack Tramiel and
Mr. Liguori at Atari to conduct a due diligence review of Atari. From January 11
through January 16, Ms. Walker and Mr. Liguori had numerous meetings and phone
calls and exchanged due diligence information and materials.
 
   
     On January 17, 1996, a meeting was held at JTS to discuss the proposed
transaction. Present at the meeting were Jack Tramiel, Sam Tramiel and Mr.
Liguori of Atari and Mr. Tandon, Mr. Mitchell and Ms. Walker of JTS. Also
present were representatives from Wilson Sonsini Goodrich & Rosati, P.C.,
counsel to Atari, and a representative of Cooley Godward. At the meeting, there
was substantial discussion regarding a proposed merger of Atari and JTS. The
meeting focused on the business opportunities, business risks and financial
positions of Atari and JTS. The parties first discussed the general terms of the
proposed merger including that the Combined Company would be managed by the
current members of JTS management, that at the time the merger agreement was
signed Atari would extend to JTS a $25.0 million bridge loan, that the bridge
loan would be convertible into JTS Series A Preferred Stock, and that JTS would
issue warrants to Atari in connection with the bridge loan if the merger were
not consummated. The parties further discussed the proposed one-for-one exchange
ratio for the Atari Common Stock, JTS Common Stock and JTS Series A Preferred
Stock. The proposal to issue common stock of the surviving company in exchange
for the outstanding stock of the corporation to be acquired was based upon a
number of factors, including tax considerations, the preservation of the
surviving company's working capital and the desire to give the JTS and Atari
stockholders an opportunity to participate as equity holders in the surviving
company. The proposed one-for-one exchange ratio of JTS and Atari stock, as
well, was based upon numerous factors, including the valuation assigned to JTS
in its most recent round of preferred stock financing, the financial forecasts
of JTS furnished to Atari, the due diligence review of the two companies, the
relative ownership interests of the JTS and Atari stockholders in the surviving
company and the historic and current trading prices of Atari Common Stock. At
the end of the meeting, Atari and JTS agreed to present the proposed transaction
to their respective boards of directors. Following the meeting, the Executive
Committee of the Atari Board of Directors met separately and considered the
advisability of obtaining a fairness opinion from an investment banking firm
with respect to the proposed merger, and Sam Tramiel was instructed to initiate
discussions with respect to obtaining such an opinion.
    
 
     On January 19, 1996, Mr. Mitchell, Ms. Walker and representatives of Cooley
Godward reported to the JTS Board of Directors on the status of the negotiations
with Atari and the preliminary results of the JTS due diligence review of Atari.
The JTS Board discussed in substantial detail the merits and the risks of a
possible business combination with Atari, as well as the alternative sources of
financing then available to the company. Following discussion, the JTS Board of
Directors instructed management to continue to pursue all financing
alternatives, including a private equity placement and a possible transaction
with Atari.
 
     Between January 20 and January 29, 1996, Atari's and JTS' management and
legal counsel continued their negotiations and due diligence reviews of the two
companies. In addition, counsel for Atari and JTS began preparation of a merger
agreement and bridge loan financing documentation.
 
     On January 30, 1996, the JTS Board of Directors met to consider the results
of management's further due diligence review of Atari and the merits of a merger
between the two companies. The JTS Board discussed the
 
                                       32
<PAGE>   37
 
terms of the proposed merger with representatives of Cooley Godward and reviewed
a draft of the merger agreement. In particular, the JTS Board considered the
possibility of obtaining bridge financing from Atari, the condition of Atari's
business and the JTS stockholders' interest in the combined company. The JTS
Board also discussed with management the status of a possible private equity
placement to meet the company's immediate capital requirements. The JTS Board
noted, among other factors, that a private equity placement would require three
months or longer to complete and that a business combination with Atari
represented an immediate source of financing. After further discussion, the JTS
Board of Directors unanimously approved the principal terms of the merger and
authorized management and Cooley Godward to proceed with the finalization of the
merger agreement and bridge loan documentation substantially on the terms
discussed by the JTS Board. A more detailed discussion of certain matters
considered by the JTS Board of Directors at this meeting is included under the
caption "-- Recommendation of the Board of Directors of JTS."
 
     On January 30, 1996, JTS notified Montgomery that it was no longer
considering a private placement to institutional investors and that it was
engaged in merger discussions with Atari, and introduced Montgomery to Atari.
Atari informed Montgomery that it wished to retain Montgomery to render a
fairness opinion, and negotiations commenced between Atari and Montgomery
regarding the terms of that engagement. On January 31, 1996, Atari and
Montgomery entered into a written engagement letter, the terms of which are
summarized below under "-- Opinion of Montgomery Securities."
 
     On February 1, 1996, the Atari Board of Directors held a telephonic meeting
to discuss the terms of the proposed merger with JTS. At the meeting, Jack
Tramiel, Sam Tramiel and Mr. Liguori reviewed with the Board the proposed terms
of the merger which had been discussed with JTS on January 17. Mr. Liguori also
presented the results of Atari's due diligence investigation of JTS. At the
meeting, the Atari Board instructed Jack Tramiel to proceed with merger
negotiations and due diligence pending further deliberations by the Atari Board.
 
     On February 5, 1996, the Atari Board of Directors met at Atari's offices
beginning at 1:00 p.m. Present were the Atari directors, representatives of
Wilson Sonsini Goodrich & Rosati, P.C., legal counsel to Atari, and
representatives from Montgomery, Atari's financial advisor. The Atari Board
reviewed the status of the negotiations regarding the proposed merger of Atari
and JTS. In particular, the Board considered the one-for-one exchange ratio,
closing conditions and termination provisions. Mr. Liguori also reported on the
results of Atari's due diligence investigation of JTS. At the meeting,
Montgomery presented the results of its review of the transaction and delivered
its oral and written opinion that the conversion ratio of Atari Common Stock
into JTS Common Stock is fair to Atari from a financial point of view, as of
February 5, 1996. Following the Montgomery presentation, the Board conducted
substantial deliberations regarding the proposed transaction including the
future prospects for Atari's business and the risks and prospects associated
with the JTS business. At the end of the meeting, the Atari Board instructed Mr.
Liguori to conduct further due diligence with respect to JTS' transaction with
Moduler Electronics and other matters. The Board deferred a final decision on
the merger pending the results of Mr. Liguori's additional due diligence. The
meeting was adjourned at 7:00 p.m. on February 5 and continued for several hours
on the morning of February 6.
 
     As the merger discussions continued, it became apparent that JTS'
acquisition of Moduler Electronics would not be completed prior to the signing
of the Merger Agreement. Accordingly, JTS agreed that the closing of JTS'
acquisition of Moduler Electronics would be a condition to Atari's obligation to
close the Merger. JTS also agreed not to effect the acquisition of Moduler
Electronics without the consent of Atari. Subsequent to the signing of the
merger agreement, JTS and Moduler Electronics negotiated the final documentation
related to the terms of their merger. As part of Atari's due diligence, Atari
was provided copies of the interim and definitive acquisition agreements.
 
     From February 5, 1996 to February 12, 1996, Jack Tramiel, Sam Tramiel and
Mr. Liguori held a series of telephonic conversations and meetings with Mr.
Tandon, Mr. Mitchell and Ms. Walker regarding the proposed transaction and due
diligence matters. There were also numerous telephone calls among Jack Tramiel,
Sam Tramiel, Michael Rosenberg (an Atari director) and Leonard Schreiber (an
Atari director) regarding the proposed transaction and the results of the
ongoing due diligence review. Similarly, JTS
 
                                       33
<PAGE>   38
 
management held a number of informal meetings with certain JTS Board members to
discuss the results the ongoing due diligence review.
 
     On February 12, 1996, the Atari Board of Directors held two telephonic
meetings to discuss the final terms of the merger agreement and the additional
due diligence materials. Prior to the meeting, each member of the Board had been
provided with a draft of the proposed merger agreement and related documents,
including disclosure schedules provided by Atari and JTS. Based on such
information and further discussions, the Atari Board of Directors unanimously
approved the merger agreement and the transactions contemplated thereby.
 
     The merger agreement and related documents were executed by the parties on
February 12, 1996, and a press release was issued on February 13, 1996.
 
     On April 8, 1996, JTS and Atari amended and restated the merger agreement
to modify the legal structure of the Merger from a consolidation of JTS and
Atari into a newly-formed Delaware corporation to a merger of Atari with and
into JTS, with JTS as the surviving company. This change in the legal structure
of the Merger did not materially modify the economic terms of the merger. The
merger agreement, as so amended and restated, is attached hereto as Annex A.
 
     On June 21, 1996, the Atari Board of Directors met to review the status of
the Merger. Jack Tramiel, who had attended recent JTS Board meetings, updated
the other members of the Board on the business prospects of JTS including the
financial targets discussed at the JTS Board meeting on June 18, 1996 and the
recent acceptance by Compaq of the Nordic 3-inch disk drive. See
"-- Forward-Looking Financial Information Provided by JTS." Based on such
information and further discussions, the Atari Board of Directors unanimously
affirmed its approval of the Merger.
 
     In June 1996, JTS and Atari amended the bridge loan documents to increase
the amount lent pursuant thereto to $30.0 million.
 
RECOMMENDATION OF THE BOARD OF DIRECTORS OF ATARI
 
     The Atari Board of Directors has determined that the Merger is fair to, and
in the best interests of, Atari and Atari's stockholders and unanimously
recommends that the Atari stockholders vote in favor of approval of the Merger
and the Merger Agreement.
 
     The Atari Board held a series of meetings at which a business combination
with or an investment in JTS was discussed. Individual members of the Board were
updated from time to time on developments. In reaching its conclusion to approve
the Merger and the Merger Agreement and to recommend that the stockholders
approve the Merger and the Merger Agreement, the Atari Board considered a number
of factors, including, without limitation, the following:
 
     -  The level of working capital required to support Atari's future business
       which was significantly downsized in late 1995 and early 1996 as Atari
       focused on licensing and software development activities.
 
     -  The future prospects for Atari's financial performance, taking into
       consideration the substantial decrease in net sales from 1994 to 1995 and
       the substantial operating losses sustained in the past several years
       among other things.
 
     -  The prospects of the business of JTS, based partly upon financial
       forecasts, including cash flow, gross margin and unit shipment
       projections, and related assumptions of JTS provided by JTS management.
 
     -  The intense competition in the video game industry.
 
     -  The significant equity position that the former stockholders of Atari
       would have in the Combined Company.
 
     -  The risks associated with the businesses of Atari and JTS.
 
     -  The treatment of the Merger as a tax-free reorganization under Section
       368(a) of the Code.
 
                                       34
<PAGE>   39
 
     -  The opinion of Montgomery that the conversion ratio of Atari Common
       Stock into JTS Common Stock is fair to Atari, from a financial point of
       view, as of February 5, 1996.
 
     -  The anticipated ability of the Combined Company to utilize Atari's
       accumulated NOLs and tax carryforwards (although the Board of Directors
       did not assign material value to the NOLs and tax carryforwards due to
       the inherent limitations on the survival of such carryovers and the
       complexity of applicable tax laws).
 
     -  The results of the due diligence review of JTS by management of Atari,
       Deloitte & Touche LLP and Wilson, Sonsini, Goodrich & Rosati, P.C.,
       counsel to Atari.
 
     The Atari Board did not attempt to prioritize the foregoing factors in any
manner.
 
RECOMMENDATION OF THE BOARD OF DIRECTORS OF JTS
 
     The JTS Board of Directors has determined that the Merger is fair to, and
in the best interests of, JTS and JTS' stockholders and unanimously recommends
that the JTS stockholders vote in favor of approval of the Merger and the Merger
Agreement.
 
     The JTS Board of Directors held a series of formal and informal meetings in
January and February 1996 at which a business combination with Atari was
discussed. During this period, an extensive financial and legal due diligence
review of Atari was conducted by members of JTS management and accountants and
legal counsel retained by JTS. Individual members of the JTS Board of Directors
were updated regularly on developments and certain members of the Board
participated actively in negotiations and discussions with Atari and the due
diligence review of Atari. In reaching its conclusion to approve the Merger and
the Merger Agreement and to recommend that the stockholders approve the Merger
and the Merger Agreement, the JTS Board considered a number of factors,
including, without limitation, the following:
 
     -  JTS' need for working capital to maintain and expand its manufacturing
       operations and research and development activities and the immediate and
       significant source of capital to fund such operations and activities that
       the merger with Atari would provide.
 
     -  The availability to JTS of alternative sources of capital and the time
       required to obtain such capital.
 
     -  The benefits to the stockholders of JTS resulting from the expected
       trading market for JTS Common Stock following the Merger, which would
       provide a means of liquidity for such stockholders' stock.
 
     -  The opportunity for JTS stockholders to continue to participate in the
       potential growth of JTS.
 
     -  The diminished equity position that the former stockholders of JTS will
       have in the Combined Company.
 
     -  The risks associated with the businesses of Atari and JTS.
 
     -  The treatment of the Merger as a tax-free reorganization under section
       368(a) of the Code.
 
     -  The anticipated ability of the Combined Company to utilize Atari's
       accumulated NOLs and tax carryforwards (although the Board of Directors
       did not assign material value to the NOLs and tax carryforwards due to
       the inherent limitations on the survival of such carryovers and the
       complexity of applicable tax laws).
 
     -  The results of the due diligence review of Atari by management of JTS
       and Cooley Godward, counsel to JTS.
 
     The JTS Board did not attempt to prioritize the foregoing factors in any
manner.
 
OPINION OF MONTGOMERY SECURITIES
 
     Pursuant to an engagement letter dated January 31, 1996, Atari retained
Montgomery to render an opinion with respect to the fairness from a financial
point of view of the consideration to be paid by Atari in connection with the
acquisition of JTS. Montgomery is a nationally recognized firm and, as part of
its investment banking activities, is regularly engaged in the valuation of
businesses and their securities in connection with merger transactions and other
types of acquisitions, negotiated underwritings, secondary
 
                                       35
<PAGE>   40
 
distributions of listed and unlisted securities, private placements and
valuations for corporate and other purposes. Atari selected Montgomery to render
a fairness opinion on the basis of Montgomery's experience and expertise in
transactions similar to the Merger and its reputation in the computer
peripherals and investment communities.
 
     On February 5, 1996, Montgomery delivered its oral and written opinion that
the conversion ratio of Atari Common Stock into JTS Common Stock was fair to
Atari, from a financial point of view, as of that date. The amount of such
consideration was determined pursuant to negotiations between Atari and JTS and
not pursuant to recommendations of Montgomery. No limitations were imposed by
Atari on Montgomery with respect to the investigations made or procedures
followed in rendering its opinion.
 
     THE FULL TEXT OF MONTGOMERY'S WRITTEN OPINION TO ATARI IS ATTACHED HERETO
AS APPENDIX C AND IS INCORPORATED HEREIN BY REFERENCE. THE FOLLOWING SUMMARY OF
MONTGOMERY'S OPINION IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL TEXT
OF THE OPINION. MONTGOMERY'S OPINION IS DIRECTED TO THE ATARI BOARD OF DIRECTORS
AND DOES NOT CONSTITUTE A RECOMMENDATION TO ANY STOCKHOLDER OF ATARI OR JTS AS
TO HOW SUCH STOCKHOLDER SHOULD VOTE WITH RESPECT TO THE MERGER. IN FURNISHING
ITS OPINION, MONTGOMERY DID NOT ADMIT THAT IT IS AN EXPERT WITHIN THE MEANING OF
THE TERM "EXPERT" AS USED IN THE SECURITIES ACT, OR THAT ITS OPINION CONSTITUTES
A REPORT OR VALUATION WITHIN THE MEANING OF SECTION 11 OF THE SECURITIES ACT,
AND STATEMENTS TO SUCH EFFECT ARE INCLUDED IN THE TEXT OF MONTGOMERY'S WRITTEN
OPINION.
 
     In connection with its opinion, Montgomery, among other things: (i)
reviewed certain publicly available financial and other data with respect to
Atari, including the consolidated financial statements for recent years and
interim periods to September 30, 1995, and certain other relevant financial and
operating data relating to Atari and JTS made available to Montgomery from
published sources and from the internal records of Atari and JTS, including the
consolidated financial statements of JTS for recent years and interim periods to
November 30, 1995; (ii) reviewed the February 2, 1996 draft of the Merger
Agreement provided to Montgomery by Atari; (iii) reviewed certain historical
market prices and trading volumes of Atari Common Stock as reported on the
American Stock Exchange; (iv) compared Atari and JTS from a financial point of
view with certain other companies in the computer peripherals industry that
Montgomery deemed to be relevant; (v) considered the financial terms, to the
extent publicly available, of selected recent business combinations of companies
in the computer peripherals industry that Montgomery deemed to be comparable, in
whole or in part, to the Merger; (vi) reviewed and discussed with
representatives of the management of Atari and JTS certain information of a
business and financial nature regarding Atari and JTS, furnished to Montgomery
by them, including the number of shares to be issued by JTS in connection with
the acquisition of Moduler Electronics; (vii) reviewed and discussed with
representatives of the management of Atari and JTS financial forecasts,
including cash flow, gross margin and unit shipment projections, and related
assumptions of JTS, provided to Montgomery by JTS management, which forecasts
and assumptions included the estimated contribution of Moduler Electronics to
JTS' financial performance; (viii) made inquiries regarding and discussed the
Merger and the draft of the Merger Agreement and other matters related thereto
with Atari's counsel; and (ix) performed such other analyses and examinations as
Montgomery deemed appropriate.
 
     In connection with its review, Montgomery assumed and relied upon the
accuracy and completeness of the foregoing information and did not assume any
responsibility for independent verification of such information. With respect to
the financial forecasts provided to it as described above, Montgomery assumed
for purposes of its opinion that such forecasts had been reasonably prepared on
bases reflecting the best available estimates and judgments of the management of
JTS at the time of preparation as to the future financial performance of JTS,
and, except as described below, that they provided a reasonable basis upon which
Montgomery could form its opinion. For purposes of its opinion and with the
agreement of management of Atari, Montgomery adjusted the financial forecasts
for JTS provided to Montgomery by the management of JTS to reflect more
conservative assumptions regarding future results of operations. Such forecasts
were based upon numerous variables and assumptions that are inherently
uncertain, including, without limitation, factors related to general economic
and competitive conditions. Accordingly, actual results could vary significantly
from those set forth in such forecasts. Montgomery has assumed no liability for
such forecasts. Montgomery also assumed that there had been no material changes
in Atari's or JTS' assets, financial condition, results of
 
                                       36
<PAGE>   41
 
operations, business or prospects since the respective dates of their last
financial statements made available to Montgomery, and that there had occurred
no material changes in the terms of JTS' proposed acquisition of Moduler
Electronics. Montgomery relied on advice of counsel and independent accountants
to Atari as to all legal and financial reporting matters with respect to Atari,
the Merger and the draft of the Merger Agreement. In addition, Montgomery did
not assume responsibility for making an independent evaluation, appraisal or
physical inspection of the assets or individual properties of Atari or JTS, nor
was Montgomery furnished with any such appraisals. Finally, Montgomery's opinion
is based on economic, monetary and market and other conditions as in effect on,
and the information made available to Montgomery as of, February 5, 1996.
 
     Montgomery further assumed, with the consent of Atari's management, that
the Merger would be consummated in accordance with the terms described in the
draft of the Merger Agreement without any amendments thereto, and without waiver
by Atari or JTS of any of the conditions to their respective obligations
thereunder.
 
     Set forth below is a brief summary of the report presented by Montgomery to
Atari's Board of Directors on February 5, 1996 in connection with its opinion.
 
     Discounted Cash Flow Analysis.  Montgomery applied a discounted cash flow
analysis to JTS financial forecasts for 1996, 1997 and 1998, prepared by JTS's
management and provided to Montgomery, and for 1999 and 2000, prepared by
Montgomery using assumptions more conservative than those underlying the JTS
management forecasts. JTS did not provide Montgomery with any financial
forecasts for periods beyond 1998. As described above, with Atari's consent
Montgomery adjusted the forecasts prepared by JTS management, and the extensions
thereof prepared by Montgomery, to reflect more conservative assumptions
regarding future results of operations. In conducting its review, Montgomery
adjusted JTS' financial projections by reducing JTS' forecasted revenues and
earnings before interest and taxes ("EBIT") by approximately 45% and 68%,
respectively. The unadjusted forecasts are referred to as the "Base Case
Forecasts," and the Base Case Forecasts as so adjusted by Montgomery are
referred to as the "Alternative Case Forecasts."
 
     In conducting its discounted cash flow analysis, Montgomery first
calculated the estimated future streams of free cash flows that JTS would
produce through the year 2000. Montgomery then estimated JTS's aggregate value
at the end of 2000 by applying multiples ranging from 7.0x to 8.0x to JTS'
estimated EBIT in 2000. Finally, Montgomery discounted such cash flow streams
and aggregate values to present values using discount rates ranging from 25.0%
to 35.0%, chosen to reflect different assumptions regarding Atari's cost of
capital, and reduced such present values by JTS' net debt as of December 31,
1995. This analysis indicated an imputed equity value (defined as aggregate
value minus net debt) of JTS of between $449.3 million and $725.9 million based
on the Base Case Forecasts, and of between $106.1 million an $192.5 million
based on the Alternative Case Forecasts. By contrast, the consideration to be
provided by Atari in the Merger, based on the Exchange Ratio and the February 2,
1996 closing sale price of Atari Common Stock on the American Stock Exchange of
$2.00 per share, equals approximately $75.7 million.
 
     Comparable Company Analysis.  Using public and other available information,
Montgomery calculated the imputed equity value of JTS based on the multiples of
estimated 1996 revenue, EBIT and net income at which three publicly traded disk
drive companies were trading on February 2, 1996. The February 2, 1996 stock
prices of the comparable companies reflected the following median multiples:
0.3x estimated 1996 revenues; 4.8x estimated 1996 EBIT; and 8.5x estimated 1996
net income. Montgomery applied the foregoing median multiples to the analogous
forecasted 1996 statistics for JTS, made applicable adjustments to reflect JTS'
net debt (defined as debt minus cash) at December 31, 1995, narrowed the
resulting range of data to exclude valuations that Montgomery deemed to be
unrealistically high, and applied a private company illiquidity discount to the
resulting totals. This analysis indicated an imputed equity value of JTS of
between $70.0 million and $175.0 million based on the Base Case Forecasts, and
of between $49.0 million and $105.0 million based on the Alternative Case
Forecasts. By contrast, the consideration to be provided by Atari in the Merger,
based on the Exchange Ratio and the February 2, 1996 closing sale price of Atari
Common Stock on the American Stock Exchange of $2.00 per share, equals
approximately $75.7 million.
 
     Comparable Transactions Analysis.  Montgomery reviewed the consideration
paid in the following twelve acquisitions of comparable disk drive and other
computer storage companies that were announced since
 
                                       37

1989 (target/acquiror): Micropolis (disk drive business)/Singapore Technologies
Industrial; Maxtor/Hyundai Electronics Industries (two separate transactions);
Conner Peripherals Inc./Seagate; Digital Equipment Corporation (disk drive
business)/Quantum; Sunward Technologies Inc./Read-Rite Corporation; Archive
Corporation/Conner Peripherals Inc.; Dastek Inc./Komag Inc.; MiniScribe
Corporation (assets)/Maxtor; Cipher Data Products Inc./Archive Corporation;
Imprimis Technology Inc./Seagate; and Irwin Magnetic Systems Inc./Cipher Data
Products Inc. Montgomery analyzed the consideration paid in such transactions as
a multiple of the target companies' revenue, EBIT and net income for the latest
twelve months ("LTM"). Such analysis yielded median multiplies of 0.5x LTM
revenue, 17.6x LTM EBIT and 18.4x LTM net income. Montgomery applied the
foregoing median multiples to the analogous forecasted 1996 statistics for JTS
and made applicable adjustments to reflect JTS' net debt at December 31, 1995.
The foregoing process yielded a range of imputed equity values of JTS as of
December 31, 1996. Montgomery then discounted that range to present values using
a discount rate of 40%, a rate generally considered to reflect the standard
venture capital return hurdle, and narrowed the resulting range of data to
exclude valuations that Montgomery deemed to be unrealistically high. This
analysis indicated an imputed equity value of JTS of between $150.0 million and
$300.0 million based on the Base Case Forecasts, and of between $100.0 million
and $250.0 million based on the Alternative Case Forecasts. By contrast, the
consideration to be provided by Atari in the Merger, based on the Exchange Ratio
and the February 2, 1996 closing sale price of Atari Common Stock on the
American Stock Exchange of $2.00 per share, equals approximately $75.7 million.
 
     No other company or transaction used in the comparable transactions
analysis as a comparison is identical to JTS or the Merger. Accordingly, an
analysis of the results of the foregoing is not mathematical; rather, it
involves complex considerations and judgments concerning differences in
financial and operating characteristics of the companies and other factors that
could affect the public trading value of the companies to which JTS and the
Merger are being compared.
 
     Contribution Analysis.  Montgomery compared the percentage interest in the
Combined Company that will be held by present stockholders of Atari and JTS
immediately following the Merger -- approximately 62% and 38%, respectively --
to the relative contributions of the two companies to various operating
statistics of the merged entity. Montgomery compared Atari's revenues for the
twelve months ended September 30, 1995 (the last date for which revenue
statistics for Atari were available) to JTS's revenues for the twelve months
ended January 15, 1996, which comparison indicated a relative contribution of
approximately 66% and 34%, respectively, for Atari and JTS. Montgomery also
compared Atari's estimated 1996 revenues (which Montgomery assumed would be
equal to Atari's revenues for the twelve months ended September 30, 1995) to
JTS' backlog of approximately $25.2 million as of January 15, 1996, to JTS's
1996 run rate revenues (defined as JTS' actual revenues for January 1 through
15, 1996, which equaled approximately $3.1 million, on an annualized basis) and
to JTS's forecasted 1996 revenues (based on the Base Case Forecasts). Such
comparisons indicated relative contributions of approximately 52% and 48%, 26%
and 74%, and 6% and 94%, respectively, for Atari and JTS.
 
     The summary set forth above does not purport to be a complete description
of the presentation by Montgomery to Atari or of the analyses performed by
Montgomery. The preparation of a fairness opinion necessarily is not susceptible
to partial analysis or summary description. Montgomery believes that its
analyses and the summary set forth above must be considered as a whole and that
selecting portions of its analyses and of the factors considered, without
considering all analyses and factors, would create an incomplete view of the
process underlying the analyses set forth in its presentation to Atari. In
addition, Montgomery may have given various analyses more or less weight than
other analyses, and may have deemed various assumptions more or less probable
than other assumptions, so that the ranges of valuations resulting from any
particular analysis described above should not be taken to be Montgomery's view
of the actual value of JTS. Although Montgomery did not consider any of the
foregoing analyses in isolation for purposes of rendering its opinion,
Montgomery does not believe that any of such analyses is inconsistent with its
opinion.
 
     In performing its analyses, Montgomery made numerous assumptions with
respect to industry performance, general business and economic conditions and
other matters, many of which are beyond the control of Atari and JTS. The
analyses performed by Montgomery are not necessarily indicative of actual values
or actual future results, which may be significantly more or less favorable than
those suggested by such analyses.
 
                                       38
<PAGE>   43
 
Such analyses were prepared solely as part of Montgomery's analysis of the
fairness of the Merger to Atari and were provided to Atari in connection with
the delivery of Montgomery's opinion. The analyses do not purport to be
appraisals or to reflect the prices at which a company might actually be sold or
the prices at which any securities may trade at any time in the future.
Montgomery used in its analyses various projections of future performance
prepared by the managements of Atari and JTS. The projections are based on
numerous variables and assumptions which are inherently unpredictable and must
be considered not certain of occurrence as projected. Accordingly, actual
results could vary significantly from those set forth in such projections.
 
     As described above, Montgomery's opinion and presentation to Atari were
among the many factors taken into consideration by Atari in making its
determination to approve, and to recommend that its stockholders approve, the
Merger.
 
     Pursuant to a letter agreement dated January 31, 1996 (the "Engagement
Letter"), Atari engaged Montgomery to render an opinion with respect to the
fairness from a financial point of view of the consideration to be paid by Atari
in connection with the acquisition of JTS. The Engagement Letter provides for
Atari to pay Montgomery a fee of $325,000, which was paid upon delivery of
Montgomery's opinion. The fee is not conditioned on the outcome of Montgomery's
opinion or whether or not such opinion was deemed to be favorable for any
party's purposes. The Engagement Letter also calls for Atari to reimburse
Montgomery for its reasonable out-of-pocket expenses. Pursuant to a separate
letter agreement, Atari has agreed to indemnify Montgomery, its affiliates, and
their respective partners, directors, officers, agents, consultants, employees
and controlling persons against certain liabilities, including liabilities under
the federal securities laws.
 
     Montgomery has not performed investment banking services for JTS, except
that Montgomery was contacted in connection with a potential private placement
of JTS securities.
 
     The Atari Board of Directors does not intend to obtain an updated fairness
opinion with respect to the Merger.
 
FORWARD-LOOKING FINANCIAL INFORMATION PROVIDED BY JTS*
 
     As a matter of course, JTS does not intend to publicly disclose
forward-looking financial information. Nevertheless, in connection with the due
diligence review of JTS' business, the Atari Board of Directors and Montgomery
reviewed preliminary financial targets furnished by JTS in January 1996. Such
financial targets indicated revenues of $445 million, gross profit of $100
million and net income of $53 million for fiscal 1997. These financial targets
were based on certain assumptions including assumptions that JTS would develop
and introduce new products on a timely basis, that Indian bank funding would be
available on a timely basis for facility expansion at Moduler Electronics, that
the notebook computer systems designed to accept the Nordic disk drive would be
released within a certain time frame, that competitive conditions within the
disk drive industry would not undergo material adverse change, that the market
for computer systems, storage upgrades to computer systems and multimedia
applications, such as digital video and video on demand and hence the market for
hard disk drives, would remain strong, and that there would be no material
adverse change in JTS' operations or business. Such assumptions involve
judgments with respect to, among other things, future economic conditions,
financial market conditions and future business decisions, all of which are
difficult or impossible to predict accurately and many of which are beyond the
control of JTS.
 
     In June 1996, JTS management provided to the Boards of Directors of Atari
and JTS updated preliminary financial targets for JTS, based on the assumption
that the Merger would be consummated in June 1996. Such financial targets for
JTS indicated revenues of $238 million, gross profit of $31 million and a net
loss of $12 million for fiscal 1997. The decline in targeted revenues and gross
profit and the increase in net

  constitute "forward-looking statements" within the meaning of Section 27A of
  the Securities Act and Section 21E of the Exchange Act and are subject to the
  safe harbors created thereby.

loss in the June 1996 targets compared to the January 1996 targets resulted
primarily from delays in the scheduled releases of notebook computers which
would incorporate JTS' Nordic drives. JTS' manufacturing schedule was changed to
reflect this delay in expected shipments of its Nordic products. As a result of
the delay in production and sales of Nordic disk drives, Palladium disk drives,
on which JTS earns a lower gross margin than Nordic drives, are expected to
comprise a greater proportion of total revenues for fiscal 1997. Accordingly,
JTS' targeted gross margin decreased from January 1996 to June 1996.
Additionally, expected funding from an Indian bank, for facilities expansion and
capital equipment for Moduler Electronics was delayed three months resulting in
a decrease in targeted production capacity. The net loss in the June 1996
updated preliminary financial targets does not include expenses associated with
the Merger, including a write-off of approximately $100 million of purchased
in-process research and development in addition to goodwill amortization, Atari
general and administrative expenses and interest expense related to the Atari
convertible debentures.
 
     While JTS believes that the assumptions underlying the preliminary
financial targets are reasonable, any of the assumptions could prove inaccurate
and, therefore, there can be no assurance that the forward-looking financial
information will prove to be accurate. In addition, as disclosed elsewhere in
this Joint Proxy Statement/Prospectus under "Risk Factors," the business and
operations of JTS are subject to substantial risks which increase the
uncertainty inherent in such preliminary financial targets. Any of the factors
disclosed under "Risk Factors" could cause the actual revenues, operating income
and net income of JTS to differ materially from the preliminary financial
targets described above. Accordingly, for these reasons it is expected that
there will be differences between the actual and targeted results, and actual
results may be materially higher or lower than those indicated above.
 
     In light of the significant uncertainties inherent in forward-looking
financial information of any kind, the inclusion of such information herein
should not be regarded as a representation by JTS, Atari or any other person
that the preliminary financial targets will be achieved. Investors are cautioned
that these preliminary financial targets should not be regarded as fact and
should not be relied upon as an accurate representation of future results.
Further, the preliminary financial targets furnished by JTS were not prepared
with a view to public disclosure or in compliance with the established
guidelines concerning financial projections promulgated by the American
Institute of Certified Public Accountants. In addition, such preliminary
financial targets do not purport to present operations in accordance with
generally accepted accounting principles and have not been audited, compiled or
otherwise examined by Arthur Andersen LLP, JTS' independent auditors, or by any
other independent auditor. Accordingly, neither Arthur Andersen LLP nor any
other independent auditor assumes any responsibility for the preliminary
financial targets disclosed herein. The preliminary financial targets are being
presented solely because they were furnished to the Atari Board of Directors and
Montgomery, and they should not be interpreted as suggesting that the Atari
Board or Montgomery relied solely upon such targets or placed any particular
emphasis upon such targets in evaluating any proposed transaction. JTS has
advised Atari and Montgomery that its preliminary financial targets were
prepared solely for internal use and capital budgeting and other management
decisions, and are subjective in many respects and thus susceptible to
interpretations and periodic revision based on actual experience and business
developments. JTS does not intend publicly to update or otherwise publicly to
revise the preliminary financial targets disclosed above to reflect
circumstances existing after the date of their preparation.
 
SUMMARY OF THE MERGER AGREEMENT
 
     The detailed terms of, and conditions to, the Merger and certain related
transactions are contained in the Merger Agreement, a copy of which is attached
hereto as Appendix A. The statements made in this Joint Proxy
Statement/Prospectus with respect to the terms of the Merger and such related
transactions are qualified in their entirety by reference to the more complete
information set forth in the Merger Agreement.
 
                                       40

EFFECTIVE TIME
 
     The Merger will become effective at such time as the Certificate of Merger
has been duly filed with the Secretary of State of the State of Nevada in
accordance with the NGCL and with the Secretary of State of the State of
Delaware in accordance with the DGCL, or at such later time as is specified in
the Certificate of Merger (the "Effective Time"). See "-- Conditions to the
Merger." It is anticipated that, if the Merger and the Merger Agreement are
approved at the respective stockholder meetings of Atari and JTS and all other
conditions to the Merger have been fulfilled or waived, the Effective Time will
occur as soon as practicable following the approval of the Merger and the Merger
Agreement by the stockholders of Atari and JTS.
 
MANNER AND BASIS OF CONVERTING ATARI COMMON STOCK
 
     Conversion of Atari Stock.  At the Effective Time, each outstanding share
of Atari Common Stock will be automatically converted into one share of JTS
Common Stock. Shares of Atari Common Stock held as treasury stock and shares of
Atari Common Stock held directly or indirectly by JTS shall not be converted
into JTS Common Stock.
 
     Based on the number of shares of Atari Common Stock, JTS Common Stock and
JTS Series A Preferred Stock outstanding as of June 18, 1996, immediately after
consummation of the Merger (assuming the conversion of all outstanding shares of
JTS Series A Preferred Stock into shares of JTS Common Stock and that none of
the holders of JTS Common Stock or JTS Series A Preferred Stock perfect
appraisal or dissenters' rights), a total of 102,814,954 shares of JTS Common
Stock would be issued and outstanding, of which 63,854,718 shares, or 62%, would
represent shares issued in the Merger upon conversion of Atari Common Stock.
 
     Fractional Shares.   No fractional shares of JTS Common Stock will be
issued as a result of the Merger. In lieu thereof, each holder of Atari Common
Stock shall receive cash (without interest) in an amount equal to the fraction
of a share of JTS Common Stock otherwise issuable to such holder multiplied by
the last sale price per share of Atari Common Stock for the trading day
preceding the date of the Effective Time as reported in The Wall Street Journal.
 
     Exchange of Certificates.  Registrar and Transfer Company, Cranford, NJ has
been designated to act as Exchange Agent for the purpose of exchanging Atari
Common Stock certificates for JTS Common Stock certificates. As promptly as
practicable after the Effective Time, instructions will be mailed to all holders
of Atari Common Stock regarding treatment of their stock certificates. After the
Effective Time, there will be no further registration of transfers of Atari
Common Stock.
 
     Upon the surrender of a certificate representing shares of Atari Common
Stock to the Exchange Agent, together with a duly executed letter of
transmittal, the holder of such certificate will be entitled to receive in
exchange therefor the number of shares of JTS Common Stock to which the holder
of Atari Common Stock is entitled pursuant to the provisions of the Merger
Agreement. Until outstanding certificates formerly representing shares of Atari
Common Stock are properly surrendered to the Exchange Agent, no dividend or
distribution payable to holders of record of JTS Common Stock shall be paid to
any holder of such outstanding certificates, but upon surrender of such
outstanding certificates by such holder there shall be paid to such holder the
amount of any dividends or distributions (without interest) theretofore paid
with respect to such whole shares of JTS Common Stock, but not paid to such
holder, and which dividends or distributions had a record date occurring on or
subsequent to the Effective Time.
 
     Until a certificate representing shares of Atari Common Stock has been
surrendered to the Exchange Agent, each such certificate shall be deemed at any
time after the Effective Time to represent the right to receive upon such
surrender the number of shares of JTS Common Stock to which the stockholder is
entitled under the Merger Agreement.
 
     ATARI STOCKHOLDERS SHOULD NOT SUBMIT THEIR STOCK CERTIFICATES UNTIL THEY
RECEIVE INSTRUCTIONS TO DO SO AFTER COMPLETION OF THE MERGER.

CONDUCT OF BUSINESS PRIOR TO THE MERGER
 
     Under the terms of the Merger Agreement, and for the period from the date
of the Merger Agreement and continuing until the earlier of the termination of
the Merger Agreement or the Effective Time of the Merger, each of Atari and JTS

above, or any action which would make any of its representations or warranties
contained in the Merger Agreement untrue or incorrect or prevent it from
performing or cause it not to perform its covenants thereunder.
 
     In addition, under the terms of the Merger Agreement, each of Atari and JTS
has agreed that, during the period from the date of the Merger Agreement and
continuing until the earlier of the termination of the Merger Agreement or the
Effective Time, and except as expressly contemplated by the Merger Agreement, it
will not, among other things, do, cause or permit any of the following, or allow
cause or permit any of its subsidiaries to do, cause or permit any of the
following, without the prior written consent of the other party: (a) enter into
any material contract or commitment, or violate, amend or otherwise modify or
waive any of the terms of any of its material contracts, other than in the
ordinary course of business consistent with past practice; (b) transfer to any

any such indebtedness or issue or sell any debt securities or guarantee any debt
securities of others; (e) revalue any of its assets, including without
limitation writing down the value of inventory or writing off notes or accounts
receivable other than in the ordinary course of business and other than as
disclosed in such party's disclosure schedule; (f) pay, discharge or satisfy in
an amount in excess of $50,000 in any one case or $250,000 in the aggregate, any
claim, liability or obligation (absolute, accrued, asserted or unasserted,
contingent or otherwise) arising other than in the ordinary course of business,
other than the payment, discharge or satisfaction of liabilities reflected or
reserved against in such party's financial statements; (g) terminate or waive
any right of substantial value, other than in the ordinary course of business;
(h) adopt or amend any employee benefit or stock purchase or option plan; (i)
commence a lawsuit other than (i) for the routine collection of bills, (ii) in
such cases where it in good faith determines that failure to commence suit would
result in the material impairment of a valuable aspect of its business, provided
that it consults with the other party prior to the filing of such a suit, or
(iii) for a breach of the Merger Agreement; (j) take, or agree in writing or
otherwise to take, any of the actions described in (a) through (i) above, or any
action which would make any of its representations or warranties contained in
the Merger Agreement untrue or incorrect or prevent it from performing or cause
it not to perform its covenants thereunder. In addition, Atari has agreed that,
during the period from the date of the Merger Agreement and continuing until the
earlier of the termination of the Merger Agreement or the Effective Time, it
shall not, without the prior written consent of JTS, make any capital
expenditures, capital additions or capital improvements except in the ordinary
course of business and consistent with past practice, and in any event not to
exceed $25,000 per quarter.
 
     Each of the parties has further agreed that from and after the date of the
Merger Agreement until the earlier of the effective time of the Merger or the
termination of the Merger Agreement in accordance with its terms, it will not,
directly or indirectly (i) solicit, initiate discuss or engage in negotiations
with any person (whether such negotiations are initiated by such party or
otherwise) or take any other action intended or designed to facilitate the
efforts of any person, other than the other party, relating to the possible
acquisition of such party or any of its subsidiaries (whether by way of merger,
purchase of capital stock, purchase of assets of otherwise) or any material
portion of its or their capital stock or assets (with any such efforts by any
such person, including a firm proposal to make such an acquisition, being
referred to as an "Acquisition Proposal"), (ii) provide non-public information
with respect to such party or any of its subsidiaries to any person relating to
a possible Acquisition Proposal by any person, other than the other party, (iii)
enter into an agreement with any person, other than the other party, providing
for a possible Acquisition Proposal, or (iv) make or authorize any statement,
recommendation or solicitation in support of any possible Acquisition Proposal
by any person other than the other party. If either party receives any
unsolicited offer or proposal to enter into negotiations relating to an
Acquisition Proposal, such party shall immediately notify the other party
thereof, including information as to the identity of the party making any such
offer and the specific terms of such offer. Each party agrees that the issuance
of an injunction or other equitable remedy is an appropriate remedy for any
breach of such agreements.
 
     Notwithstanding the foregoing, nothing contained in the Merger Agreement
prevents the Board of Directors of Atari (or its agents pursuant to its
instructions) from taking any of the following actions: (i) informing any third
party of the foregoing conditions or providing a copy of the Merger Agreement
(other than the JTS Disclosure Schedule) to any third party and (ii)
considering, negotiating, approving and recommending to the stockholders of
Atari an unsolicited, bona fide, written Acquisition Proposal which the Board of
Directors of Atari determines in good faith (after consultation with its
financial advisors and after consultation with outside counsel as to whether the
Board of Directors is required to do so in order to discharge properly its
fiduciary duties to stockholders under applicable law) would result in a
transaction more favorable to Atari's stockholders from a financial point of
view than the Merger (a "Superior Atari Proposal"). However, in the event Atari
were to accept a Superior Atari Proposal, JTS would be entitled to convert the
Atari loan into shares of JTS Series A Preferred Stock.
 
ADDITIONAL AGREEMENTS
 
     Each of Atari and JTS shall afford the other with reasonable access prior
to the Effective Time to (a) all of such party's properties, books, contracts,
commitments and records and (b) all other information
 
                                       44
<PAGE>   49
 
concerning the business, properties and personnel of such party as the other
party may reasonably request. Each party shall promptly apply for or otherwise
seek, and use its best efforts to obtain, all consents and approvals required to
be obtained by it for the consummation of the Merger, and shall use its best
efforts to obtain all necessary consents, waivers and approvals under any of its
material contracts in connection with the Merger for the assignment thereof.
 
     Each person or entity who holds one percent (1%) or more of the outstanding
shares of JTS capital stock and each person or entity who holds more than five
percent (5%) of the outstanding shares of Atari capital stock shall execute and
deliver a "continuity of interest certificate" (the "Continuity of Interest
Certificate") prior to the Closing. The Continuity of Interest Certificate shall
contain certain representations relating to such stockholders' intention to sell
or dispose of their respective holdings of Atari or JTS capital stock. The
Combined Company shall be entitled to place appropriate legends on the
certificates evidencing any JTS Common Stock to be received by such persons or
entities pursuant to the terms of the Merger Agreement. Such legends shall refer
to, among other things, restrictions on disposition of JTS Common Stock pursuant
to Rule 145 under the Securities Act.
 
     Certain stockholders of Atari and JTS, prior to the execution of the Merger
Agreement, executed and delivered a Voting Agreement pursuant to which such
stockholders agreed to: (a) refrain from selling or otherwise disposing of any
shares of Atari or JTS capital stock, as applicable, prior to the Effective Time
or the date of termination of the Merger Agreement; (b) vote such shares in
favor of the Merger Agreement, the Merger and any matter that could reasonably
be expected to facilitate the Merger; and (c) deliver to Atari or JTS, as
applicable, an irrevocable proxy to vote such shares in favor of the Merger
Agreement and the Merger.
 
     At the Effective Time, each outstanding option to purchase shares of Atari
Common Stock under the Atari Stock Option Plan, whether vested or unvested, will
be assumed by JTS. Each such option so assumed by JTS under the Merger Agreement
shall continue to have, and be subject to, the same terms and conditions set
forth in the Atari Stock Option Plan.
 
     After the Effective Time, JTS shall (to the extent not prohibited by law)
indemnify and hold harmless, and pay in advance expenses, costs, damages,
settlements and fees to each director or officer of Atari serving as such as of
the date of the Merger Agreement as provided under Nevada law or the Articles of
Incorporation or Bylaws of Atari, or any indemnification agreement to which
Atari and such officer or director is a party, in each case as in effect at the
date of the Merger Agreement, which provisions shall survive the Merger and
shall continue in full force and effect after the Effective Time.
 
BOARD OF DIRECTORS AND OFFICERS FOLLOWING MERGER
 
     At the Effective Time, the directors of the Combined Company will be
Sirjang L. Tandon, David T. Mitchell, Alain L. Azan, Jean D. Deleage, Roger W.
Johnson, Lip-Bu Tan, Jack Tramiel and Michael Rosenberg. Messrs. Tandon,
Mitchell, Azan, Deleage, Johnson and Tan are currently directors of JTS, and
Messrs. Tramiel and Rosenberg are currently directors of Atari. The executive
officers of JTS immediately prior to the effective time will be the executive
officers of the Combined Company. The parties have also agreed that Jack Tramiel
or a person designated by Jack Tramiel shall be a member of each committee of
the Board of Directors of the Combined Company.

TERMINATION, AMENDMENT AND WAIVER
 
     The Merger Agreement may be terminated by mutual written agreement of Atari
and JTS, or by either Atari or JTS, if (a) as a result of a breach by the other
party of a representation, warranty, covenant or agreement set forth in the
Merger Agreement which has or can reasonably be expected to have a material
adverse effect on such other party which breach is not cured within five days
after written notice from the other (except that no cure period is provided for
a breach which by its nature cannot be cured), or (b) there shall be any final
action taken, or any statute, rule, regulation or order enacted which would
prohibit JTS' ownership or operation of all or a material portion of the
business of Atari, or which compels JTS or Atari to dispose of or otherwise
relinquish all or a material portion of either such party's assets.
 
     The Merger Agreement may be terminated by any party if (a) the required
approvals of the stockholders of JTS and Atari are not obtained at the
respective stockholder meetings, (b) the closing of the Merger has not occurred
on or before July 31,1996, (c) there is a final, non-appealable order of a
federal or state court in effect preventing consummation of the Merger, or (d)
if the Atari Board of Directors accepts, approves or recommends a Superior Atari
Proposal to the Atari stockholders.
 
     The Merger Agreement may be amended by Atari or JTS at any time before or
after approval by the Atari stockholders or the JTS stockholders, provided that
an amendment made subsequent to the adoption of the Merger Agreement by the
stockholders of JTS and Atari, shall not (a) alter or change the amount or kind
of consideration to be received on conversion of the Atari Common Stock, (b)
alter or change any term of the Certificate of Incorporation of JTS to be
effected by the Merger or (c) alter or change any of the terms and conditions of

     At any time prior to the Effective Time any party to the Merger Agreement

MERGER EXPENSES
 
     Atari and JTS will equally bear the costs of solicitation of proxies from
their stockholders, all printing and mailing costs in connection with the
preparation and mailing of this Joint Proxy Statement/Prospectus to Atari and
JTS stockholders, all Commission filing fees with respect to the Registration
Statement of which this Joint Proxy Statement/Prospectus is a part, and all
costs of qualifying the shares of JTS Common Stock under state blue sky laws. In
addition to solicitation by mail, the directors, officers and employees of Atari
and JTS may solicit proxies from stockholders by telephone, telegram or letter
or in person, but will not be specially compensated for such activities.
Brokers, nominees, fiduciaries and other custodians have been requested to
forward solicitation material to the beneficial owners of Atari Common Stock
held of record by them. Such custodians will be reimbursed by Atari for their
reasonable expenses incurred in that connection. If the Merger is consummated,
all costs and expenses incurred in connection with the Merger not previously
paid will be paid by the Combined Company.
 
CERTAIN OTHER ITEMS RELATED TO THE MERGER
 
ACCOUNTING TREATMENT
 
     For accounting purposes, the Merger is treated as if Atari acquired JTS. A
new basis of accounting will be established for the assets and liabilities of
JTS. The new basis reflects the allocation of the purchase price
 
                                       47
<PAGE>   52
 
to the JTS assets and liabilities on the basis of their fair values at the time
the proposed transaction was announced. The aggregate purchase price to be
allocated includes the outstanding common stock of JTS, valued using $2.50 per
share which is the representative value of the Atari Common Stock at the time
the proposed transaction was announced, as well as the value of JTS options and
warrants and direct costs of the acquisition. Subsequent to the Merger, the
financial statements of the Combined Company will reflect the combined financial
position, results of operations and cash flows of Atari and JTS based on the new
basis of accounting for JTS and the historic cost basis of Atari. Pro forma
combined condensed financial statements are presented herein giving effect to
the Merger as if the transaction occurred, for purposes of the pro forma
combined financial position of the Combined Company, on March 31, 1996, and for
purposes of the pro forma combined results of operations of the Combined
Company, on the first day of each of the periods presented. The allocation of
the purchase price in the pro forma statements was based on an independent
analysis of the tangible and intangible assets of JTS, which will be revised as
updated information becomes available at the Effective Time. Under the purchase
accounting method, giving effect to the Merger, existing technology and goodwill
in the amount of approximately $22.0 million and $11.7 million, respectively,
are expected to be recognized by the Combined Company. It is anticipated that
the Combined Company will amortize the resulting existing technology and
goodwill over periods of three and seven years, respectively, which will have an
adverse effect on its results of operations. In addition, upon the consummation
of the Merger, in the third quarter of calendar year 1996, the Combined Company
expects to expense approximately $100.0 million of purchased in-process
technology. See "Unaudited Pro Forma Combined Condensed Financial Statements."
 
RESALE OF JTS COMMON STOCK
 
     The shares of JTS Common Stock to be issued to holders of Atari Common
Stock in the Merger have been registered under the Securities Act by a
registration statement, of which this Joint Proxy Statement/Prospectus is a
part, thereby allowing such shares of JTS Common Stock to be traded without
restriction under the Securities Act by all such holders, except that such
holders who are "affiliates" (as such term is defined for purposes of Rule 145
promulgated under the Securities Act) of Atari will be subject to restrictions
on transferability as provided in Rule 145.
 
     Notwithstanding the Merger, certain shares of JTS Common Stock will
continue to be subject to contractual restrictions on transfer, rights of
repurchase and other provisions (and corresponding restrictive legends on
certificates issued representing such shares), if any, to the same extent as
were applicable immediately prior to the Effective Time, all as set forth in the
restricted stock purchase agreements entered into by the holders of such shares
of JTS Common Stock upon the purchase of such shares by such holder and any
restrictive legends set forth on any certificates representing such shares. See
"Information Regarding JTS Corporation -- Management of JTS -- Executive
Compensation."
 
CERTIFICATE OF INCORPORATION AND BYLAWS OF COMBINED COMPANY
 
     Upon consummation of the Merger, the Certificate of Incorporation and the
Bylaws of JTS will be amended and restated as approved by the JTS stockholders
in May 1996, and such documents will be the Certificate of Incorporation and the
Bylaws of the Combined Company. See "Comparison of Rights of Stockholders of
Atari and JTS."
 
ASSUMPTION OF ATARI OPTIONS
 
     Upon consummation of the Merger, each option to purchase Atari Common Stock
then outstanding will be assumed by JTS and will be converted automatically into
an option to purchase the same number of shares of JTS Common Stock at an
exercise price per share equal to the exercise price per share of the Atari
option. The other terms of the Atari options, including vesting schedules, will
remain unchanged.
 
                                       48
<PAGE>   53
 
ASSUMPTION OF ATARI DEBENTURES
 
     Upon consummation of the Merger, all of Atari's obligations under its
outstanding 5 1/4% convertible subordinated debentures due April 29, 2002 (the
"Atari Debentures") will be assumed by JTS. The Atari Debentures are presently
convertible into Atari Common Stock at a conversion price of $16.3125 per share
and, following the Merger, will be convertible into JTS Common Stock at the same
conversion price. The other terms of the Atari Debentures will remain unchanged.
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
   
     As of June 28, 1996, members of the Board of Directors and executive
officers of Atari beneficially owned approximately 23,952,129 shares (37%) of
the outstanding Common Stock of Atari. As of the same date, members of the Board
of Directors and executive officers of JTS beneficially owned approximately
9,318,000 shares (99%) of the outstanding JTS Common Stock and approximately
14,120,000 shares (48%) of the outstanding JTS Series A Preferred Stock.
Following the consummation of the Merger, the executive officers and the members
of the Board of Directors of the Combined Company will beneficially own
approximately 35,740,000 shares (35%) of the outstanding Common Stock of the
Combined Company. See "-- Summary of the Merger Agreement -- Board of Directors
and Officers Following the Merger," "Information Regarding Atari Corporation --
Principal Stockholders of Atari" and "Information Regarding JTS Corporation --
Principal Stockholders of JTS."
    
 
     Mr. David T. Mitchell, Chief Executive Officer, President and a director of
JTS, Mr. Kenneth D. Wing, Executive Vice President, Research and Development
Quality/Reliability of JTS, and Ms. W. Virginia Walker, Executive Vice
President, Finance and Administration and Chief Financial Officer of JTS, have
purchased 2,000,000 shares, 300,000 shares and 250,000 shares of restricted JTS
Common Stock, respectively, pursuant to restricted stock purchase agreements.
Each of the agreements provides that such shares of JTS Common Stock shall fully
vest over a four year period; provided, however, such shares of JTS Common Stock
shall immediately vest in the event that there occurs a change of control of JTS
and, within three years thereafter, the holder of such JTS Common Stock is
reassigned to a lesser position, terminated without cause or relocated. The
Merger constitutes a change of control under such restricted stock purchase
agreements.
 
     In March 1996, Mr. Mitchell and Mr. Sirjang L. Tandon, JTS' Chairman of the
Board and Corporate Technical Strategist, each purchased 1,000,000 shares of JTS
Common Stock at a purchase price of $1.00 per share. All of such shares are
subject to a right of repurchase at cost in favor of JTS, which repurchase
option lapses as to all such shares after five years of service with JTS;
provided, however, that with respect to each individual, JTS' right of
repurchase will lapse at the rate of one-eighth of the total shares purchased in
September 1996 and as to 1/48th of the total shares purchased per month
thereafter if the Merger closes. In addition, at the discretion of JTS' Board of
Directors, the right of repurchase with respect to Mr. Mitchell's 1,000,000
shares of JTS Common Stock may be caused to lapse as to all such shares at any
time.
 
GOVERNMENTAL AND REGULATORY APPROVALS
 
     Under the provisions of the HSR Act, certain acquisitions of voting
securities may not be consummated unless certain information has been filed with
the Federal Trade Commission (the "FTC") and the Antitrust Division of the
Department of Justice (the "Antitrust Division") and the applicable waiting
period under the HSR Act has expired or been terminated. Neither Atari nor JTS
is required to file HSR forms under the HSR Act in connection with the Merger,
except to the extent that the acquisition of JTS Common Stock by certain Atari
stockholders in connection with the Merger may separately be subject to the
premerger notification and waiting period requirements of the HSR Act. All
necessary filings have been made and the applicable waiting period has
terminated with respect to such filings.
 
     At any time before or after the Effective Time, and notwithstanding the
termination of the HSR Act waiting period, the Antitrust Division, the FTC or a
private person could seek under the antitrust laws, among other things, to
enjoin the Merger or to cause Atari or JTS to divest itself, in whole or in
part, of a portion of its business, or the Combined Company to divest itself, in
whole or in part, of any of the businesses of Atari or
 
                                       49
<PAGE>   54
 
JTS. There can be no assurance that a challenge to the Merger will not be made
or that, if such a challenge is made, Atari and JTS will prevail.
 
     Other than the waiting period under the HSR Act, Atari and JTS are aware of
no governmental or regulatory approvals required for consummation of the Merger,
other than compliance with the federal securities laws and applicable securities
laws of the various states.
 
RELATED TRANSACTIONS
 
ATARI LOAN TO JTS
 
     On February 13, 1996, Atari loaned $25.0 million to JTS pursuant to a
Subordinated Secured Convertible Promissory Note (the "Note") which is secured
by substantially all of the assets of JTS. Interest accrues on the unpaid
principal amount of the Note at the rate of 8.5% per annum. The Note was amended
in June 1996 to increase the amount lent pursuant thereto to $30.0 million. The
Note provides that JTS shall repay the outstanding principal and interest under
the Note on September 30, 1996 if the Merger has not occurred prior to such
time. The Note is expressly subordinated to outstanding indebtedness in
connection with JTS' primary bank loan agreement, up to an amount of $5.0
million at any one time. In addition, Atari's security interest in JTS' assets
is junior to security interests previously obtained by a bank and certain
equipment lessors. The amount of the senior obligations was approximately $9.1
million at January 28, 1996. In addition, the Note provides that JTS may incur
(a) indebtedness to trade creditors in the ordinary course of business, (b)
contingent obligations consisting of guarantees of the obligations of vendors
and suppliers of JTS in respect to transactions entered into in the ordinary
course of business, (c) indebtedness with respect to capital lease obligations
and indebtedness secured by certain permitted liens, (d) other indebtedness, not
exceeding $1.0 million in the aggregate at any time, and (e) obligations with
respect to extensions, renewals or refinancings of any of the items in (a)-(d),
provided that the principal amount thereof is not increased or the terms thereof
are not modified to impose more burdensome terms upon JTS.
 
     Under the terms of the Note, the occurrence of any of the following shall
constitute an event of default entitling Atari to declare immediately due and
payable all outstanding obligations under the Note: (a) failure by JTS to pay
when due any principal or interest payment required under the Note; (b) failure
by JTS to observe or perform its agreements regarding prohibitions on certain
transactions and on the use of proceeds from the Note; (c) breach of any
representation or warranty made in connection with the Note or the Merger
Agreement; (d) default by JTS under certain existing loan obligations, the
effect of which is to cause indebtedness of JTS in the amount of $250,000 or
more to become due prior to its stated date of maturity; (e) involuntary or
voluntary bankruptcy proceedings with respect to JTS; (f) a final judgment or
order for the payment of money in excess of $250,000 being rendered against JTS
in which such judgment or order remains undischarged for a period of 30 days; or
(g) the uncured breach by JTS with respect to certain other obligations
specified in the Note.
 
     In the event that the Merger Agreement is terminated, either party may,
under certain conditions, elect to convert the outstanding indebtedness under
the Note into shares of JTS Series A Preferred Stock in an amount determined by
dividing the aggregate amount of the indebtedness to be converted by the
"Conversion Price" then in effect. The initial Conversion Price is $1.00 per
share, subject to adjustments for stock splits and similar events. Atari may
effect a conversion upon (a) a mutual written consent of JTS and Atari, (b) a
breach of any representation, warranty or agreement in the Merger Agreement by
JTS, provided that Atari has not materially breached its obligations under the
Merger Agreement at such time, (c) the failure of the parties to consummate the
Merger by July 31, 1996, or (d) failure by JTS' stockholders to approve the
Merger. JTS may effect a conversion of the outstanding indebtedness under the
Note in the event that (x) Atari breaches any representation, warranty or
agreement contained in the Merger Agreement, provided that JTS has not
materially breached its obligations under the Merger Agreement at such time, (y)
Atari's stockholders do not approve the Merger, or (z) the Atari Board of
Directors shall have accepted, approved or recommended to the Atari Stockholders
a Superior Atari Proposal.
 
     In the event that either Atari or JTS elects to convert at least $5.0
million of indebtedness outstanding under the Note into shares of JTS Series A
Preferred, JTS shall be obligated to issue to Atari warrants to
 
                                       50
<PAGE>   55
 
purchase shares of JTS Series A Preferred Stock. Pursuant to the terms of the
Note, JTS shall, upon the conversion of such outstanding indebtedness, be
obligated to issue a warrant to purchase up to 9,375,000 shares of JTS Series A
Preferred. Each warrant to be issued by JTS pursuant to the Note shall have an
exercise price of $2.00 per share, subject to adjustment on certain events, and
a term of five years. The shares of JTS Series A Preferred issuable upon
exercise of any warrants issued pursuant to the Note shall be entitled to
registration rights on parity with the existing registration rights held by the
holders of JTS Series A Preferred Stock.
 
VOTING AGREEMENTS
 
     In connection with the Merger, certain stockholders of Atari and JTS have
entered into Voting Agreements. The terms of such Voting Agreements provide (i)
that such stockholders will not transfer (except as may be specifically required
by court order), sell, exchange, pledge (except in connection with a bona fide
loan transaction) or otherwise dispose of or encumber their shares of Atari
Common Stock, JTS Common Stock or JTS Series A Preferred Stock, as the case may
be, beneficially owned by them, or any new shares of such stock they may
acquire, at any time prior to the effective time or earlier termination of the
Merger, and (ii) that such stockholders will vote all shares of Atari Common
Stock, JTS Common Stock or JTS Series A Preferred Stock, as the case may be,
beneficially owned by them in favor of the approval of the Merger Agreement and
the Merger. Such voting agreements are accompanied by irrevocable proxies
whereby the stockholders of Atari provide to JTS, and the stockholders of JTS
provide to Atari, the right to vote their shares on the proposals relating to
the Merger Agreement and the Merger at the Atari Special Meeting and JTS Special
Meeting, respectively. Holders of approximately 43% of the shares of Atari
Common Stock, 91% of the shares of JTS Common Stock and 70% of the shares of JTS
Series A Preferred Stock entitled to vote at the respective stockholder meetings
have entered into such Voting Agreements and irrevocable proxies.
 
APPRAISAL AND DISSENTERS' RIGHTS
 
GENERAL
 
     Stockholders of JTS who do not vote in favor of the Merger may, under
certain circumstances and by following the procedures prescribed by the DGCL,
exercise appraisal rights and receive cash for their shares of JTS Common Stock
and JTS Series A Preferred Stock. Alternatively, although JTS is a Delaware
corporation and is therefore subject to DGCL, the CGCL provides that JTS may be
subject to California law with respect to dissenters' rights. Accordingly,
pursuant to Chapter 13 of the CGCL, stockholders of JTS who do not vote in favor
of the Merger and who comply with the requirements of the CGCL will have a right
to demand payment for, and appraisal of the "fair value" of, their shares
("Dissenting Shares"). Although a dissenting stockholder may choose to proceed
under one or both of the states' statutes, the dissenting stockholder must
specify which statute the stockholder is proceeding under and must follow the
appropriate procedures under either the DGCL or the CGCL or suffer termination
or waiver of such rights.
 
DELAWARE APPRAISAL RIGHTS
 
     If the Merger is consummated, dissenting holders of JTS Common Stock and
JTS Series A Preferred Stock may be entitled to have the "fair value" (exclusive
of any element of value arising from the accomplishment or expectation of the
Merger) of their shares immediately prior to the Effective Time paid to them by
complying with the provisions of Section 262 of the DGCL.
 
     The following is a brief summary of Section 262, which sets forth the
procedures for dissenting from the Merger and demanding statutory appraisal
rights. This summary does not purport to be a complete statement of the
provisions of the Delaware Law relating to the rights of JTS stockholders to an
appraisal of the value of their shares and is qualified in its entirety by
reference to Section 262, the full text of which is attached hereto as Appendix
D. Failure to follow these procedures exactly could result in the loss of
appraisal rights (if available). This Joint Proxy Statement/Prospectus
constitutes notice to holders of JTS Common Stock and JTS Series A Preferred
Stock concerning the availability of appraisal rights under Section 262.
 
     Under Section 262, a stockholder of record wishing to assert appraisal
rights must hold the shares of stock on the date of making a demand for
appraisal rights with respect to such shares and must continuously hold
 
                                       51
<PAGE>   56
 
such shares through the Effective Time. Stockholders who desire to exercise
their appraisal rights (if available) must satisfy all of the conditions of
Section 262. A written demand for appraisal of shares must be filed with JTS
before the taking of the vote on the Merger. This written demand for appraisal
of shares must be in addition to and separate from any proxy vote abstaining
from or voting against the Merger. Any such abstention or vote against the
Merger will not constitute a demand for appraisal within the meaning of Section
262.
 
     Stockholders electing to exercise their appraisal rights (if available)
under Section 262 must not vote for approval of the Merger. If a stockholder
returns a signed proxy but does not specify a vote against approval of the
merger or a direction to abstain, the proxy will be voted for approval of the
Merger, which will have the effect of waiving that stockholder's appraisal
rights (if available).
 
     A demand for appraisal must be executed by or for the stockholder of
record, fully and correctly, as such stockholder's name appears on the share
certificate. If the shares are owned of record in a fiduciary capacity, such as
by a trustee, guardian or custodian, this demand must be executed by or for the
fiduciary. If the shares are owned by or for more than one person, as in a joint
tenancy or tenancy in common, such demand must be executed by or for all joint
owners. An authorized agent, including an agent for two or more joint owners,
may execute the demand for appraisal for a stockholder of record; however, the
agent must identify the record owner and expressly disclose the fact that, in
exercising the demand, he is acting as agent for the record owner. A person
having a beneficial interest in JTS Common Stock or JTS Series A Preferred Stock
held of record in the name of another person, such as a broker or nominee, must
act promptly to cause the record holder to follow the steps summarized below and
in a timely manner to perfect whatever appraisal rights the beneficial owner may
have.
 
     A record owner, such as a broker, who holds JTS Common Stock or JTS Series
A Preferred Stock as a nominee for others may exercise his or her right of
appraisal with respect to the shares for all or less than all of the beneficial
owners of shares as to which he or she is the record owner. In such case, the
written demand must set forth the number of shares covered by such demand. Where
the number of shares is not expressly mentioned, the demand will be presumed to
cover all shares outstanding in the name of such record owner.
 
     A JTS stockholder who elects to exercise appraisal rights (if available)
should mail or deliver his or her written demand to JTS at its address at 166
Baypointe Parkway, San Jose, California 95134, Attention: W. Virginia Walker,
Corporate Secretary. The written demand for appraisal should specify the
stockholder's name and mailing address, and that the stockholder is thereby
demanding appraisal of his or her JTS stock. If appraisal rights are available
in connection with the Merger, within ten days after the Effective Time, JTS
must provide notice of the Effective Time to all of its stockholders who have
complied with Section 262 and have not voted for approval of the Merger.
 
     Within 120 days after the Effective Time, any stockholder who has satisfied
the requirements of Section 262 may deliver to JTS a written demand for a
statement listing the aggregate number of shares not voted in favor of the
merger and with respect to which demands for appraisal have been received and
the aggregate number of holders of such shares.
 
     Within 120 days after the Effective Time (but not thereafter), either JTS
or any stockholder who has complied with the required conditions of Section 262
may file a petition in the Delaware Court of Chancery (the "Court") demanding a
determination of the fair value of the dissenting shares. If no petition for
appraisal is filed with the Court within 120 days after the Effective Time,
stockholders' rights to appraisal (if available) will cease and stockholders
will be entitled to receive shares of JTS Common Stock as provided in the Merger
Agreement. Any stockholder who desires a petition to be filed is advised to file
it on a timely basis. JTS has no present intention to file such a petition if
demand for appraisal is made.
 
     Upon the filing of any petition by a stockholder in accordance with Section
262, service of a copy will be made upon JTS, which will, within 20 days after
service, file in the office of the Register in Chancery in which the petition
was filed, a duly verified list containing the names and addresses of all
stockholders who have demanded payment for their shares and with whom agreements
as to the value of their shares have not been reached by JTS.
 
     If a petition for an appraisal is filed in a timely fashion, after a
hearing on the petition, the Court will determine which stockholders are
entitled to appraisal rights and will appraise the shares owned by these
 
                                       52
<PAGE>   57
 
stockholders, determining the fair value of such shares, exclusive of any
element of value arising from the accomplishment or expectation of the Merger,
together with a fair rate of interest to be paid, if any, upon the amount
determined to be fair value. In determining fair value, the Court is to take
into account all relevant factors.
 
     JTS stockholders considering seeking appraisal of their shares should note
that the fair value of their shares determined under Section 262 could be more,
the same or less than the consideration they would receive pursuant to the
Merger Agreement if they did not seek appraisal of their shares. The costs of
the appraisal proceeding may be determined by the Court and taxed against the
parties as the Court deems equitable in the circumstances.
 
     Any stockholder who has duly demanded appraisal in compliance with Section
262 will not, after the Effective Time, be entitled to vote for any purpose the
shares subject to demand or to receive payment of dividends or other
distributions on such shares, except for dividends or distributions payable to
stockholders of record at a date prior to the Effective Time.
 
     At any time within 60 days after the Effective Time, any stockholder will
have the right to withdraw his or her demand for appraisal and to accept the
terms offered in the Merger Agreement. After this period, a stockholder may
withdraw his or her demand for appraisal and receive payment for his or her
shares as provided in the Merger Agreement only with the consent of JTS. No
petition demanding appraisal may be dismissed without approval of the Court.
 
     Pursuant to the Merger Agreement, JTS will give Atari prompt notice of any
demands received by JTS, and Atari will have the right to participate in all
negotiations and proceedings with respect to the demands. JTS will not, except
with the prior written consent of Atari, make any payment with respect to, or
settle or offer to settle, any such demands.
 
     Cash received pursuant to the exercise of appraisal rights may be subject
to federal or state income tax. See "-- Certain Federal Income Tax
Considerations."
 
     The foregoing summary of the applicable provisions of Section 262 is not
intended to be a complete statement of such provisions and is qualified in its
entirety by reference to such Section, the full text of which is attached as
Appendix D-1 to this Joint Proxy Statement/Prospectus.
 
CALIFORNIA DISSENTERS' RIGHTS
 
     By virtue of Section 2115 of the CGCL, if holders of JTS Common Stock and
JTS Series A Preferred Stock exercise dissenters' rights in connection with the
Merger under Chapter 13 of the CGCL ("Chapter 13"), any shares of JTS Common
Stock and JTS Series A Preferred Stock as to which such dissenters' rights are
exercised will be converted into the right to receive such consideration as may
be determined to be due with respect to such Dissenting Shares pursuant to the
laws of the State of California.
 
     The following summary of the provisions of Chapter 13 is not intended to be
a complete statement of such provisions and is qualified in its entirety by
reference to the full text of Chapter 13, a copy of which is attached hereto as
Appendix D-2 and is incorporated herein by reference.
 
     If the Merger is approved by the required vote of JTS' stockholders, each
holder of shares of JTS Common Stock and JTS Series A Preferred Stock who does
not vote in favor of the Merger and who follows the procedures set forth in
Chapter 13 will be entitled to have shares of JTS Common Stock and JTS Series A
Preferred Stock purchased by JTS for cash at their fair market value. Abstention
of the stockholder from voting will not waive the stockholders' dissenter's
rights. Voting against the proposed Merger will not constitute the written
demand on the corporation for purchase of the Dissenting Shares as required
under Chapter 13. The fair market value of shares of JTS Common Stock and JTS
Series A Preferred Stock will be determined as of the day before the first
announcement of the terms of the proposed Merger, excluding any appreciation or
depreciation in consequence of the proposed Merger and therefore valuing the
shares of JTS Common Stock and Series A Preferred Stock as if the Merger had not
occurred.
 
     Within ten days after approval of the Merger by JTS' stockholders, JTS must
mail a notice of such approval (the "Approval Notice") to all stockholders who
have not voted in favor of the Merger, together with
 
                                       53
<PAGE>   58
 
a statement of the price determined by JTS to represent the fair market value of
the applicable Dissenting Shares, a brief description of the procedures to be
followed in order for the stockholder to pursue dissenters' rights, and a copy
of Sections 1300-1304 of Chapter 13. The statement of price by JTS constitutes
an offer by JTS to purchase all Dissenting Shares at the stated amount.
 
     A stockholder of JTS electing to exercise dissenters' rights must, within
thirty days after the date on which the Approval Notice is mailed to such
stockholder, mail or deliver the written demand to JTS stating that such holder
is demanding purchase of his or her shares of JTS Common Stock and/or JTS Series
A Preferred Stock, stating the number of shares which JTS must purchase, what
the stockholder claims to be the fair market value of such shares and enclosing
the share certificates for endorsement by JTS. The statement of fair market
value constitutes an offer by the stockholder to sell the shares at such price.
A dissenting stockholder may not withdraw a demand for payment unless JTS
consents to it.
 
     If JTS and the stockholder agree that the shares are Dissenting Shares and
agree upon the price of the shares, JTS must pay the stockholder the agreed upon
price plus interest thereon at the legal rate from the date of the agreement on
Dissenting Shares within thirty days from the later of (i) the date of the
agreement on Dissenting Shares, or (ii) the date all contractual conditions to
the Merger are satisfied.
 
     If JTS denies that the shares are Dissenting Shares, or if JTS and the
stockholder fail to agree upon the fair market value of shares of capital stock,
then within six months after the date the Approval Notice was mailed to
stockholders, any stockholder who has made a valid written purchase demand and
who has not voted in favor of approval and adoption of the Merger may file a
complaint in California superior court requesting a determination as to whether
the shares are Dissenting Shares or as to the fair market value of such holder's
shares of JTS Common Stock and/or JTS Series A Preferred Stock, or both.

                   CERTAIN FEDERAL INCOME TAX CONSIDERATIONS
 
     The following discussion summarizes the material federal income tax
consequences of the exchange of shares of Atari capital stock for JTS capital
stock pursuant to the Merger. This summary is based upon opinions of counsel
(the "Tax Opinions") delivered by Wilson Sonsini Goodrich & Rosati, P.C. and
Cooley Godward Castro Huddleson & Tatum (collectively "Counsel") that the Merger
will constitute a "reorganization" within the meaning of Section 368 of the
Internal Revenue Code of 1986, as amended (a "Reorganization").
 
     Atari and JTS stockholders should be aware that this discussion does not
deal with all federal income tax considerations that may be relevant to
particular stockholders of Atari and JTS in light of their particular
circumstances, such as stockholders who are banks, insurance companies,
tax-exempt organizations, dealers in securities, foreign persons or who do not
hold their Atari or JTS capital stock as capital assets or who acquired their
shares in connection with stock option or stock purchase plans or in other
compensatory transactions. In addition, the following discussion does not
address the tax consequences of the Merger under foreign, state or local tax
laws or the tax consequences of transactions effectuated prior or subsequent to
or concurrently with the Merger (whether or not such transactions are in
connection with the Merger), including, without limitation, transactions in
which Atari capital stock is acquired or JTS capital stock is disposed of.
ACCORDINGLY, ATARI AND JTS STOCKHOLDERS ARE URGED TO CONSULT THEIR OWN TAX
ADVISORS AS TO THE SPECIFIC TAX CONSEQUENCES OF THE MERGER, INCLUDING THE
APPLICABLE FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO THEM OF THE
MERGER IN THEIR PARTICULAR CIRCUMSTANCES.
 
     Subject to the limitations and qualifications referred to herein, Counsel
is of the opinion that the Merger will qualify as a Reorganization which will
result in the following federal income tax consequences:
 
     (a) No gain or loss will be recognized by holders of Atari capital stock
solely upon their receipt of JTS capital stock solely in exchange for Atari
capital stock in the Merger (except to the extent of cash received in lieu of a
fractional share of JTS capital stock).
 
     (b) The aggregate tax basis of the JTS capital stock received by Atari
stockholders in the Merger will be the same as the aggregate tax basis of Atari
capital stock surrendered in exchange therefor less the tax basis, if any,
allocated to fractional share interests.
 
     (c) The holding period of the JTS capital stock received in the Merger will
include the period for which the Atari capital stock surrendered in exchange
therefor was held, provided that the Atari capital stock is held as a capital
asset at the time of the Merger.
 
     (d) Cash payments received by holders of Atari capital stock in lieu of a
fractional share will be treated as if a fractional share of JTS capital stock
had been issued in the Merger and then redeemed by JTS. A stockholder of Atari
receiving such cash will generally recognize gain or loss upon such payment,
equal to the difference (if any) between such stockholder's basis in the
fractional share and the amount of cash received.
 
     (e) A shareholder who exercises appraisal or dissenters' rights with
respect to a share of JTS capital stock and who receives payment for such stock
in cash should generally recognize capital gain or loss (if such share was held
as a capital asset at the time of the Merger) measured by the difference between
the shareholder's basis in such share and the amount of cash received, provided
that such payment is neither essentially equivalent to a dividend nor has the
effect of a distribution of a dividend (a "Dividend Equivalent Transaction"). A
sale of capital stock of JTS pursuant to an exercise of appraisal or dissenters'
rights will generally not be a Dividend Equivalent Transaction if, as a result
of such exercise, the shareholder exercising dissenters' rights and all parties
related to such Shareholder own no shares of JTS Stock (either actually or
constructively with the meaning of Section 318 of the Code) after the Merger.
If, however, a stockholder's sale for cash of JTS capital stock pursuant to an
exercise of appraisal or dissenters' rights is a Dividend Equivalent
Transaction, then such shareholder will generally recognize income for federal
income tax purposes in an amount up to the entire amount of cash so received.
 
     (f) Neither JTS nor Atari will recognize material amounts of gain solely as
a result of the Merger.
 
                                       55
<PAGE>   60
 
     No ruling has been or will be obtained from the Internal Revenue Service
(the "IRS") in connection with the Merger. Atari and JTS stockholders should be
aware that the Tax Opinions do not bind the IRS and that the IRS is therefore
not precluded from successfully asserting a contrary opinion. The Tax Opinions
are also subject to certain limitations and qualifications, they are based upon
certain factual assumptions, and are subject to the truth and accuracy of
certain representations made by Atari and JTS. Of particular importance are
certain representations relating to the Code's "continuity of shareholder
interest" and "continuity of business enterprise" requirements.
 
     To satisfy the continuity of shareholder interest requirement, Atari
shareholders must not, pursuant to a plan or intent existing at or prior to the
Merger, dispose of or transfer so much of either (i) their Atari capital stock
in anticipation of the Merger or (ii) the JTS capital stock to be received in
the Merger (collectively, "Planned Dispositions"), such that Atari shareholders,
as a group, would no longer have a significant equity interest in the Atari
business being conducted by JTS after the Merger. Atari shareholders will
generally be regarded as having a significant equity interest as long as the
number of shares of JTS capital stock received in the Merger less the number of
shares subject to Planned Dispositions (if any) represents, in the aggregate, a
substantial portion of the entire consideration received by the Atari
shareholders in the Merger. To satisfy the continuity of business enterprise
requirement, JTS must either (i) continue the historic business conducted by
Atari or (ii) use a significant portion of the historic business assets of Atari
in a business.
 
     A successful IRS challenge to the Reorganization status of the Merger would
result in the Merger being treated as a taxable sale of Atari's assets.
Additionally, a successful IRS challenge to such Reorganization status would
result in Atari stockholders recognizing taxable gain or loss with respect to
each share of Atari capital stock surrendered equal to the difference between
the stockholder's basis in such share and the fair market value, as of the
Effective Time, of the JTS capital stock received in exchange therefor. In such
event, a stockholder's aggregate basis in the JTS capital stock so received
would equal its fair market value and the holding period for such stock would
begin the day after the Effective Time.

       JTS' ACQUISITION OF THE DISK DRIVE DIVISION OF MODULER ELECTRONICS
 
     Moduler Electronics is located in Madras, India and was founded in 1986 by
members of the family of Sirjang L. Tandon, JTS' Chairman and Corporate
Technical Strategist, as a contract manufacturer of power supplies for computers
and hard disk drive subassemblies. In December 1994, Moduler Electronics
received Indian government approval to manufacture hard disk drives. At
approximately the same time, Moduler Electronics discontinued production of hard
disk drive subassemblies for customers other than JTS. In March 1995, JTS
entered into a verbal agreement to acquire the hard disk drive division of
Moduler Electronics for 1,911,673 shares of JTS Series A Preferred Stock and a
warrant to purchase 500,000 shares of JTS Common Stock at an exercise price of
$.25 per share. JTS subsequently assumed operational and management control of
certain portions of the hard disk drive business of Moduler Electronics. The
verbal agreement contemplated that prior to JTS' acquisition, Moduler
Electronics would divest itself of certain voice coil assembly and other
operations not directly involved in its hard disk drive business.
 
     In April 1996, following Moduler Electronics' divestiture of its voice coil
business and businesses unrelated to its hard disk drive operations, JTS
purchased 90% of the outstanding capital stock of Moduler Electronics in
consideration for 1,911,673 shares of JTS Series A Preferred Stock and a warrant
to purchase 750,000 shares of JTS Common Stock at an exercise price of $.25 per
share. The warrant is immediately exercisable as to 500,000 shares of JTS Common
Stock and becomes exercisable with respect to the remaining 250,000 shares when
certain borrowings and credit facilities in the amount of $29 million become
available to Moduler Electronics. The 250,000 share portion of the warrant
related to the credit facilities of Moduler Electronics will be valued and
recorded as additional interest expense over the term of the borrowings, if and
when such portion of the warrant becomes exercisable.
 
     In connection with the acquisition of the hard disk drive business of
Moduler Electronics, JTS agreed not to compete in the head stack manufacturing
business within India for a period of five years, provided that JTS may
manufacture head stacks for its internal requirements. In return, the former
owners of Moduler Electronics agreed not to compete in the disk drive
manufacturing business within India for a period of five years. In addition, JTS
granted certain registration rights with respect to the shares of JTS capital
stock issued in the acquisition. JTS has a right of first refusal to purchase
the remaining 10% equity interest in Moduler Electronics at 10% of the net book
value of Moduler Electronics at the time of the purchase.
 
     Since JTS began hard disk drive production in early 1995, JTS has conducted
substantially all of its manufacturing operations at the Moduler Electronics
facility. As of April 26, 1996, Moduler Electronics employed 1,760 individuals.
The Madras facility presently occupies 85,000 square feet in a single building,
4,000 square feet of which are designated a "clean room" environment. At this
facility, JTS is adding production lines and expanding its clean room
environment. JTS believes that locating its manufacturing operations in India
represents an important element of its manufacturing strategy due to the local
availability of a high-quality, low-cost technical labor pool. See "Information
Regarding JTS Corporation -- Business of JTS -- Manufacturing."

          UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS
 
     The following unaudited pro forma condensed combined financial statements
give effect to the Merger of JTS and Moduler Electronics which was consummated
on April 4, 1996 and will be accounted for as a purchase. The accompanying pro

acquisition of Moduler Electronics by JTS took place on that date and combines
JTS' and Moduler Electronics' balance sheets as of January 28, 1996. The
accompanying pro forma combined condensed statement of operations for the year
ended January 28, 1996 assumes that the acquisition took place as of the
beginning of fiscal 1996, and combines JTS' and Moduler Electronics' statements
of operations for the year ended January 28, 1996. The pro forma combined
condensed statements of operations do not include the effect of any nonrecurring
charges directly attributable to the acquisition.
 
     In March 1995, JTS agreed to acquire the hard disk drive division of
Moduler Electronics and subsequently assumed operational and management control
of certain portions of the hard disk drive business of Moduler Electronics. The
purchase price included 1,911,673 shares of JTS Series A Preferred Stock and a
warrant to purchase JTS Common Stock at an exercise price of $0.25 per share in
exchange for 90% of the outstanding capital stock of Moduler Electronics. Actual
statements of the companies will be combined after the consummation date with no
retroactive restatements. The accompanying pro forma combined condensed
financial statements should be read in conjunction with JTS' and Moduler
Electronics' historical financial statements and related notes thereto.

NOTE 1.  PURCHASE PRICE ALLOCATION
 
     The purchase price of the acquisition of Moduler Electronics is computed as
follows (in thousands):
 
<TABLE>
                <S>                                                   <C>
                Preferred stock.....................................  $1,911
                Warrants............................................     125
                                                                      -------
                                                                      $2,036
                                                                      =======
</TABLE>
 
     The preferred stock is valued at $1.00 per share, such number of shares and
     the value per share were agreed to in March 1995. The price per preferred
     share was identical to the price per preferred share received by the
     Company in cash sales to unrelated parties in February and September 1995.
     The warrant to purchase 500,000 shares of common stock at $.25 was valued
     at $125,000 and reflects the higher value of the preferred stock relative
     to the common stock. Subsequent to the March 1995 agreement to purchase
     Moduler Electronics, JTS assumed operational and management control of
     certain portions of the Disk Drive Unit and funded certain of the start-up
     losses. Accordingly, JTS expensed 90% of the Unit's loss in its historical
     financial statements.
 
     The purchase price is expected to be allocated as follows (in thousands):

                     ATARI CORPORATION AND JTS CORPORATION
 
          UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL STATEMENTS
 
     The following unaudited pro forma condensed combined financial statements
give effect to the proposed merger of Atari and JTS. The merger is subject to
shareholder and regulatory approval and other conditions. The unaudited pro
forma condensed combined balance sheet has been prepared as if the acquisition,
which will be accounted for as a purchase of JTS by Atari, was consummated as of
March 31, 1996. Such pro forma balance sheet combines Atari's balance sheet as
of March 31, 1996 and the balance sheet of JTS as of April 28, 1996. Although
the business combination will result in Atari merging into the JTS legal entity,
the substance of the transaction is that Atari, a public company with
substantially greater operating history and net worth, will own approximately
62% of the combined equity at the date of the acquisition.
 
     The aggregate purchase price of $112.3 million has been allocated to the
acquired assets and liabilities of JTS. Included in the pro forma purchase price
are the approximately 40 million shares of outstanding common stock of JTS,
assuming conversion of all outstanding preferred stock of JTS, the value of the
assumed JTS options and warrants of $11.1 million and the estimated direct
transaction costs. The common stock, options and warrants were valued using
$2.50 per share which is the representative value of Atari stock at the time the
proposed transaction was announced. The fair value of JTS assets and liabilities
will be revised as updated information becomes available at the Effective Time.
Such preliminary appraisal allocated $119.0 million to purchased technology,
$97.0 million of which represented in-process research and development. The
$97.0 million will be expensed upon the closing of the Merger as the technology
had not yet reached technological feasibility and does not have alternative
future uses.
 
     The unaudited pro forma condensed combined statements of operations for the
year ended December 31, 1995 give effect to the proposed merger as if the
acquisition was completed at the beginning of the year and combines Atari's
statement of operations as of December 31, 1995 with the pro forma combined
statement of operations for JTS and Moduler Electronics for the year ended
January 28, 1996. The unaudited pro forma condensed combined statements of
operations for the quarter ended March 31, 1996 give effect to the proposed
merger as if the acquisition was completed at the beginning of the quarter and
combines Atari's statement of operations as of March 31, 1996 with the JTS pro
forma statement of operations for the quarter ended April 28, 1996. Such
statements do not include the effect of the approximately $97.0 million
nonrecurring charge for in-process research and development, as such charges
will be included in the consolidated statement of operations in the third
calendar quarter of 1996. Such statements also exclude Atari's extraordinary
gain generated from the Atari Debentures extinguished in 1995 and the $6.3
million gain on sale of marketable securities in the first quarter of 1996.
 
     This method of combining historical financial statements for the
preparation of the pro forma condensed combined statements is for presentation
only. Actual statements of operations of the companies will be combined from the
closing date of the acquisition with no retroactive restatements. The unaudited
pro forma condensed combined financial statements are provided for illustrative
purposes only and is not necessarily indicative of the combined financial
position or combined results of operations that would have been reported had the
Merger occurred on the dates indicated, nor do they represent a forecast of the
combined financial position or results of operations for any future period. The
unaudited pro forma condensed combined financial statements should be read in
conjunction with the historical financial statements and accompanying notes for
Atari, JTS and Moduler Electronics.

NOTE 2 -- PRO FORMA ADJUSTMENTS
 
     The following pro forma adjustments have been made to the unaudited pro
forma condensed combined financial statements:
 
     (a) --  Reflects the value of all outstanding JTS common stock and the fair
             value of JTS options.
 
     (b) -- Reflects the fair value of JTS common stock warrants.
 
     (c) --  Reflects elimination of JTS common and preferred stock, deferred
             compensation, goodwill and shareholders' deficit.
 
     (d) -- Reflects allocation of purchase price to acquired equipment,
            existing technology and goodwill.
 
     (e) --  Reflects a one-time charge for purchased in-process technology.
 
     (f) --  Reflects amortization of purchased existing technology on a
             straight-line basis over three years.
 
     (g) --  Reflects amortization of goodwill on a straight-line basis over
             seven years.
 
     (h) -- Reflects depreciation of the step-up of equipment on a straight-line
            basis over three years.
 
     (i) --  Reflects accrual of direct transaction costs.
 
     (j) --  Reflects the outstanding common stock of JTS assuming the
             conversion of outstanding preferred stock of JTS excluding the
             impact of stock options and warrants which are antidilutive.
 
     (k) -- Reflects elimination of note between Atari and JTS.
 
     (l) --  Reflects elimination of nonrecurring gain on sale of a marketable
             security.
 
     No deferred tax adjustments is made as the deferred tax assets, consisting
primarily of net operating loss carryforwards, exceed the deferred tax
liabilities and the excess of the deferred tax assets over the deferred tax
liabilities is offset by a valuation allowance due to the uncertainty
surrounding the realization.

                NOTES TO UNAUDITED PRO FORMA CONDENSED COMBINED
               FINANCIAL STATEMENTS OF ATARI AND JTS (CONTINUED)
 
NOTE 3 -- IN-PROCESS RESEARCH AND DEVELOPMENT
 
     The allocation of the purchase price among identifiable intangible assets
was based on a preliminary independent appraisal of the fair value of those
assets. The fair value of JTS assets and liabilities will be revised as updated
information become available at the Effective Time. Such preliminary appraisal
allocated $97.0 million to purchased in-process research and development. The
$97.0 million will be expensed in the third calendar quarter upon closing as the
technology had not yet reached technological feasibility and does not have
alternative future uses. The unaudited pro forma condensed combined statements
of operations do not include this one-time charge for purchased in-process
technology as it represents a material nonrecurring charge in accordance with
the rules for the preparation of pro forma financial statements.
 
NOTE 4 -- DEFERRED COMPENSATION
 
     Upon the closing of the merger, JTS will record a one-time expense charge
of approximately $4.3 million of deferred compensation which it is currently
amortizing. Such expense has not been recorded in the accompanying pro forma
financial statements.

 MANAGEMENT'S DISCUSSION AND ANALYSIS OF PRO FORMA COMBINED FINANCIAL CONDITION
  AND PRO FORMA COMBINED RESULTS OF OPERATIONS OF THE COMBINED COMPANY FOR THE
                          QUARTER ENDED MARCH 31, 1996
 
     The following discussion should be read in conjunction with Management's
Discussion and Analysis of Financial Condition and Results of Operations of
Atari and JTS and the introduction to the pro forma financial statements on page
59. The pro forma combined results are not necessarily indicative of what would
have occurred had the acquisition actually been made at the beginning of each of
the respective periods presented or of future operations of the Combined
Company.
 
     The net loss on a pro forma basis for the Combined Company was $22.5
million on net revenues of $18.9 million. The Combined Company expects sales of
Atari's Jaguar and related products to decline substantially in 1996 and
thereafter as a result of Atari's decision to focus its efforts on selling its
inventory of Jaguar and related products and to emphasize its existing licensing
and development activities related to multimedia entertainment software. The
Combined Company is expected to focus a substantial portion of its resources on
the disk drive portion of its business which is expected to represent a
substantial portion of the operations of the Combined Company. Sales of disk
drives in the Combined Company are expected to increase during 1996 with the
initiation of shipments of the Nordic 3-inch disk drives to Compaq late in the
second quarter and the introduction of additional disk drive products with
higher performance characteristics and increased capacities beyond JTS' current
1.6 gigabyte product.* There can be no assurance that the Combined Company will
be successful in the production and shipment of these products.
 
     The Combined Company anticipates that it will have a five year period
during which it will not pay taxes on its operations in India. Further, the
Combined Company's operations in India are in a tax exempt facility. These tax
benefits, to the extent the Combined Company is able to generate profitable
operations to utilize them, will provide the Combined Company with a lower tax
rate than would otherwise be the case. No assurance can be given, however, that
the Combined Company will achieve profitable operations in India or be able to
utilize these tax benefits or achieve a lower tax rate.
 
     Upon consummation of the Merger, the subordinated convertible note due from
JTS to Atari will be canceled. The unaudited pro forma Combined Balance Sheets
reflect cash and cash equivalents of $28.9 million and working capital of $14.8
million. The Combined Company will need significant additional financing
resources over the next several years for facilities expansion, capital
expenditures, working capital, research and development and vendor tooling. In
order for the Combined Company to accelerate or increase planned expenditures or
to the extent orders do not materialize as currently projected, additional
capital will be required. Furthermore, certain equipment and receivable
financing as well as existing term loans in place are contingent on compliance
with stringent financial covenants. The Combined Company will pursue equity
and/or debt financing in the near future to meet its funding requirements. The
issuance of equity or convertible debt securities would result in dilution of
the voting control of existing stockholders of the Combined Company and could
result in dilution to earnings per share. The issuance of debt securities would
provide to the holders of those securities seniority over the holders of JTS
Common Stock issued in the Merger. There can be no assurance that the Combined
Company will be able to maintain its current financing facilities or obtain
additional financing as needed on acceptable terms or at all. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations of
JTS."

                    INFORMATION REGARDING ATARI CORPORATION
 
BUSINESS OF ATARI
 
     Atari was incorporated under the laws of Nevada in May 1984. From 1984 to
1992, Atari designed, manufactured and marketed proprietary personal computers
and video games and related software. Over the past several years, Atari has
undergone significant change. In 1992 and 1993, Atari significantly downsized
operations, decided to exit the computer business and focused on its video game
business. As a result, revenues from computer products as a percentage of total
revenues declined from 67% in 1993 to 16% in 1994 and 12% in 1995, while sales
of entertainment systems and related software and peripheral products and the
receipt of royalties represented the balance of revenues in each such year.
These actions resulted in significant restructuring charges for closed
operations and write-downs of computer and certain video game inventories in
1992 and 1993.
 
     While restructuring, Atari developed its 64-bit Jaguar interactive
multimedia entertainment system, which was introduced in selected markets in the
fourth quarter of 1993. For 1995 and 1994, total sales of Jaguar and related
products were $9.9 million and $29.3 million, respectively, and represented 68%
and 76% of Atari's net revenues, respectively. These Jaguar sales were
substantially below Atari's expectations, and Atari's business and financial
results were materially adversely affected in 1995 as Atari continued to invest
heavily in Jaguar game development, entered into arrangements to publish certain
licensed titles and reduced the retail price for its Jaguar console unit. Atari
attributes the poor performance of Jaguar to a number of factors including (i)
extensive delays in development of software for the Jaguar which resulted in
reduced orders due to consumer concern as to when titles for the platform would
be released and how many titles would ultimately be available, and (ii) the
introduction of competing products by Sega and Sony in May 1995 and September
1995, respectively.
 
     By late 1995, Atari recognized that despite the significant commitment of
financial resources that were devoted to the Jaguar and related products, it was
unlikely that Jaguar would ever become a broadly accepted video game console or
that Jaguar technology would be broadly adopted by software title developers. As
a result, Atari decided to significantly downsize its Jaguar operations. This
downsizing resulted in significant reductions in Atari's workforce, and
significant curtailment of research and development and sales and marketing
activities for Jaguar and related products. Accordingly, Atari decided to focus
its efforts on selling its inventory of Jaguar and related products and to
emphasize its existing licensing and development activities related to
multimedia entertainment software for various platforms. Atari presently has a
substantial unsold inventory of Jaguar and related products and there can be no
assurance that such inventory can be sold at current prices. Despite the
introduction of four additional game titles in the first quarter of 1996, sales
of Jaguar and related software have remained disappointing due to uncertainty
about Atari's commitment to the Jaguar platform, increased price competition and
pending competitive product introductions. As a result of continued
disappointing sales, management revised estimates and wrote-down inventory by an
additional $5.0 million in the first quarter of 1996. As of the end of May 1996,
Atari had approximately 90,000 units of Jaguar in inventory.
 
PRODUCTS
 
     Atari's principal products are described below:
 
     Jaguar Entertainment System.  Atari introduced its 64-bit Jaguar
interactive multimedia entertainment system in late November 1993 into selected
markets. During 1994, Atari rolled out a nationwide program and commenced
initial shipments into Europe. From its launch through the end of 1994, Jaguar's
suggested retail price was $249.99. As a result of competition and cost
reductions, during the first quarter of 1995, Atari reduced the retail price of
Jaguar to $149.99. The current retail price of Jaguar is $99.99. Despite its
substantially lower retail price, sales of Jaguar continue to be disappointing.
Volume sales of Jaguar and related software in 1996 have consisted primarily of
a large order from a new European customer. Atari is also pursuing wholesale
sales channels in the U.S. as well as licensing opportunities. There can be no
assurance that Atari's substantial unsold inventory of Jaguar and related
software can be sold at current or reduced
 
                                       70
<PAGE>   75
 
prices, if at all. In addition, any further decrease in the value of such
inventory could result in additional inventory write-downs by Atari.
 
     The Jaguar is a 64-bit interactive multimedia system that incorporates two
proprietary chips developed by Atari which are specialized for multimedia
entertainment. The proprietary chips include four processors (graphics
processing unit, object processor, blitter and digital signal processor) and a
standard Motorola 68000 microprocessor. The computational speed of the system is
approximately 44 MIPS and the bus bandwidth is 106.4 megabytes per second. The
video features include 24-bit graphics with up to 16.8 million colors and a 3-D
engine which can render 3-D shaded or texture mapped polygons in real time. The
sound system is based on a high-speed custom digital signal processor dedicated
to audio. The audio is 16-bit compact disk ("CD") quality from cartridge-based
software, and can be processed from simultaneous sources of audio data. This
allows for very realistic sounds in the software, including human voices.
Through the use of a compression technology customized by Atari (called
"JAGPEG"), software developers can compress data to the point that a 100-megabit
game can fit into a 16-megabit ROM cartridge. This allows for more exciting
experiences both visually and in game play due to the vast amount of data
available.
 
     Jaguar Software Titles.  From 1994 through 1995, Atari developed titles for
the Jaguar primarily under contract with third party software developers. To
date, Atari has published approximately 45 software titles for the Jaguar. These
titles include an array of licensed and nonlicensed titles, some of which
utilize 3-D graphics, high speed animation, 16.8 million colors, full motion
video, motion capture techniques and 16-bit stereo sound. Atari's software
library includes titles which are cartridge based (ROM chips) and CD based.
Since 1995, the development of titles for Jaguar has been curtailed
substantially and Atari is currently developing a very limited number of titles
which it expects to publish in either cartridge or CD format. In addition to
Atari's software development efforts, in 1994 and 1995 Atari licensed
independent software vendors ("ISVs") to develop and publish titles for the
Jaguar. Atari is not aware of any current development of Jaguar titles by ISVs
and does not expect any such development in the foreseeable future.
 
     Jaguar Peripherals.  Atari offers a CD-ROM peripheral for the Jaguar that
enables software end users to have full motion video clips and more complex
games than are available on cartridges. Publishers can take advantage of lower
media cost and quicker turnaround on orders with CD-ROM software as compared to
a ROM cartridge. The CD-ROM peripheral is a double speed player that can play
Jaguar video games, regular audio CD's and CD + G (graphics). The suggested
retail price of the CD-ROM peripheral is $149.99. The success of the CD-ROM
peripheral is substantially dependent on the size of the installed base of
cartridge-based Jaguar consoles.
 
     PC Software.  As a result of Atari's investment in game design, art and
programming for its Jaguar software, Atari has ported certain of its Jaguar
titles to the IBM PC compatible platform. Atari intends to publish and/or
license these titles in 1996. In this regard, Atari commenced shipment of the PC
CD-ROM version of Tempest 2000 in Europe during the first quarter of 1996.
 
     Library of Titles.  In 1996, Atari plans to increase its efforts to license
titles from its game library to third party publishers. Atari has over 100
titles in its game library, including the following:

COMPETITION
 
     The video game business is intensely competitive. Since its introduction in
late 1993, Jaguar has failed to achieve broad market acceptance. Atari does not
expect that Jaguar, even at its substantially reduced price, will ever become a
broadly accepted video game console, or that Jaguar technology will be broadly
adopted by software title developers. The video game industry is also
characterized by unpredictable and rapid shifts in the popularity of certain
platforms, by severe price competition, and by frequent new technology and
product
 
                                       71
<PAGE>   76
 
introductions. In this regard, numerous companies have introduced or have
developed and are expected to introduce video game consoles that are or may
become competitive with Jaguar. In addition, an increasing number of
entertainment titles are being developed for or ported to the PC platform. Most
of Atari's competitors have greater experience and expertise in 3D graphics and
multimedia technology and have substantially greater engineering, marketing and
financial resources than Atari. Jaguar presently competes with products offered
by the following companies:
 
     - Nintendo commenced development, in collaboration with Silicon Graphics,
       Inc., of the Nintendo 64 player, expected to be released in Autumn 1996
       in the United States. Nintendo also sells the 16 bit Super NES at a
       retail price of $99.95.
 
     - Sega commenced shipment of the Sega Saturn in the United States in May
       1995 with a current retail price of $299.00. Sega also sells the 16 bit
       Genesis at a retail price of $99.95.
 
     - Sony released the Sony PlayStation in the United States in late 1995 with
       a current retail price of $299.00.
 
     - The 3DO Company licenses the 3DO Interactive Multiplayer System console
       architecture for retail sale worldwide.
 
MARKETING AND DISTRIBUTION
 
     Atari distributes its products domestically through various independent
channels. Jaguar is sold primarily through national retailers, consumer
electronic specialty stores and distributors of electronic products. European
sales are conducted from Atari's European headquarters in London, U.K. Jaguar
and Atari's PC titles are sold in European markets through substantially the
same channels of distribution as those in the United States. Net sales outside
North America for fiscal years 1995, 1994 and 1993 constituted approximately
44%, 40% and 75%, respectively, of total net revenues. No single customer
accounted for 10% or more of total net revenues for the years ended December 31,
1995, 1994 or 1993.
 
RESEARCH AND DEVELOPMENT
 
     Most of Atari's products, including Jaguar, were developed by its internal
engineering and software groups as well as independent software developers under
contract with Atari. Atari's research and development expenses totaled $5.4
million, $5.8 million and $4.9 million in 1995, 1994, and 1993, respectively.
Atari has significantly downsized its research and development efforts and
currently has five employees dedicated to such efforts. As a result, Atari
expects its research and development expenses to decline substantially in 1996.*
 
     Atari's current development efforts are dedicated to developing a limited
number of Jaguar software titles and porting certain existing Jaguar titles to
the PC platform. As part of this development process, Atari has agreements with
third parties to develop and/or license properties. Under these agreements,
Atari will make payments to these parties as either development fees and/or
advance royalties, and is obligated to make certain minimum royalty guarantees
on future sales. There can be no assurance that all payments for development
fees and/or advance royalties will be recoverable through future sales of
products.
 
MANUFACTURING
 
     Atari has placed no manufacturing orders for the Jaguar console since
mid-1995. Based on current and expected sales and inventory levels, Atari does
not intend to pursue additional Jaguar manufacturing. The Jaguar console unit
was assembled in the United States by a third-party subcontractor under a
manufacturing arrangement. The agreement may be canceled by either party with 90
days' notice. Jaguar software products

and accessories are manufactured by several suppliers and are assembled by
subcontractors. Atari believes that it could readily replace these sources of
supply and assembly, if necessary.
 
INTELLECTUAL PROPERTY RIGHTS
 
     Atari has exclusive use of its "Atari" name and "Fuji" logo in all areas
other than coin-operated arcade video game use. Atari also has a portfolio of
other intellectual properties including patents, trademarks, and copyrights
associated with its video game and computer businesses. Atari believes its
patents, trademarks and other intellectual property are important assets. As of
December 31, 1995, Atari held over 150 patents in the United States and other
jurisdictions which expire from 1996 to 2010 and had applications pending for
three additional patents. There can be no assurance that any of these patent
rights will be upheld in the future or that Atari will be able to preserve any
of its other intellectual property rights. Atari has in the past received
communications from third parties asserting rights to certain of its
intellectual property. Atari has also been involved in several major lawsuits
regarding its intellectual property, including a suit with Nintendo which was
settled in March 1994 and a suit with Sega which was settled in September 1994.
In the event any third party were to make a valid claim with respect to Atari's
intellectual property and a license were not available on commercially
reasonable terms, Atari's business, financial condition and results of
operations would be materially and adversely affected. Litigation, which has in
the past and could in the future result in substantial costs and diversion of
resources, may also be necessary to enforce Atari's patents or other
intellectual property rights or to defend against third-party infringement
claims. The occurrence of litigation relating to patent infringement or other
intellectual property matters, regardless of the outcome, could have a material
adverse effect on Atari's business, financial condition and results of
operations.
 
BACKLOG
 
     Orders are usually placed by purchasers on an as-needed basis, are
sometimes cancelable before shipment, and are usually filled from inventory
shortly after receipt. Atari currently has a substantial inventory of finished
products and product components for which there are no orders. Although Atari is
taking steps to realize revenue from such inventory, Atari recognized
substantial inventory write-downs in 1995 and the first quarter of 1996 and
there can be no assurance that additional write-downs will not be required.

     Due to disappointing sales of Jaguar and related products, Atari reduced
its workforce from 101 persons at December 31, 1994 to 73 persons at December
31, 1995 and 31 persons at March 31, 1996. Atari had 22 employees at June 19,
1996, including 15 in the United States and seven outside the United States.
None of the employees are represented by a labor union. Atari considers its
employee relations to be good.
 
PROPERTIES
 
     Atari leases its 7,200 square feet headquarters facility in Sunnyvale,
California under a lease which expires in 2001. Atari also leases a 20,200
square feet warehouse facility in Santa Clara, California, a 33,600 square feet

   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
                              OPERATIONS OF ATARI
 
     This Joint Proxy Statement/Prospectus contains forward-looking statements
within the meaning of Section 27A of the Securities Act of 1933 and Section 21E
of the Securities Exchange Act of 1934. Actual results could differ materially
from those projected in the forward-looking statements as a result of certain
factors, including those set forth under "Risk Factors -- Risk Factors Related
to the Business of Atari" and elsewhere in this Joint Proxy
Statement/Prospectus.
 
     Over the past several years, Atari has undergone significant change. In
1992 and 1993, Atari significantly downsized operations, decided to exit the
computer business and focused on its video game business. As a result, revenues
from computer products as a percentage of total revenues declined from 67% in
1993 to 16% in 1994 and 12% in 1995, while sales of entertainment systems and
related software and peripheral products and the receipt of royalties
represented the balance of revenues in each such year. These actions resulted in
significant restructuring charges for closed operations and write-downs of
computer and certain video game inventories in 1992 and 1993.
 
     While restructuring, Atari developed its 64-bit Jaguar interactive
multimedia entertainment system, which was introduced in selected markets in the
fourth quarter of 1993. For 1995 and 1994, total sales of Jaguar and related
products were $9.9 million and $29.3 million, respectively, and represented 68%
and 76% of Atari's net revenues, respectively. These Jaguar sales were
substantially below Atari's expectations, and Atari's business and financial
results were materially adversely affected in 1995 as Atari continued to invest
heavily in Jaguar game development, entered into arrangements to publish certain
licensed titles and reduced the retail price for its Jaguar console unit. Atari
attributes the poor performance of Jaguar to a number of factors including (i)
extensive delays in development of software for the Jaguar which resulted in
reduced orders due to consumer concern as to when titles for the platform would
be released and how many titles would ultimately be available, and (ii) the
introduction of competing products by Sega and Sony in May 1995 and September
1995, respectively.
 
     By late 1995, Atari recognized that despite the significant commitment of
financial resources that were devoted to the Jaguar and related products, it was
unlikely that Jaguar would ever become a broadly accepted video game console or
that Jaguar technology would be broadly adopted by software title developers. As
a result, Atari decided to significantly downsize its Jaguar operations. This
downsizing resulted in significant reductions in Atari's workforce, and
significant curtailment of research and development and sales and marketing
activities for Jaguar and related products. Accordingly, Atari decided to focus
its efforts on selling its inventory of Jaguar and related products and to
emphasize its existing licensing and development activities related to
multimedia entertainment software for various platforms. Atari presently has a
substantial unsold inventory of Jaguar and related products and there can be no
assurance that such inventory can be sold at current prices. Despite the
introduction of four additional game titles in the first quarter of 1996, sales
of Jaguar and related software have remained disappointing due to uncertainty
about Atari's commitment to the Jaguar platform, increased price competition and
pending competitive product introductions. As a result of continued
disappointing sales, management revised estimates and wrote-down inventory by an
additional $5.0 million in the first quarter of 1996. As of the end of May 1996,
Atari had approximately 90,000 units of Jaguar in inventory.
 
YEAR ENDED DECEMBER 31, 1995 COMPARED TO YEAR ENDED DECEMBER 31, 1994
 
     Total revenues for 1995 were $14.6 million compared to $38.7 million for
1994. Sales of Jaguar and related products represented 68% and 76% of total
revenues for 1995 and 1994, respectively, and sales of other products and
royalties represented the balance of revenues in each such year. The reduction
in revenues was primarily the result of lower unit volumes of Jaguar products
and lower average selling prices of Jaguar and certain of its software titles.
In the first quarter of 1995, Atari reduced the suggested retail price of Jaguar
from its original price of $249.99 to $149.99. The current suggested retail
price of Jaguar is $99.99. As a result of the Jaguar price reductions, the
substantial curtailment of sales and marketing activities for Jaguar and the
substantial curtailment of efforts by Atari and independent software developers
to develop additional software
 
                                       76
<PAGE>   81
 
titles for Jaguar, Atari expects sales of Jaguar and related products to decline
substantially in 1996 and thereafter.*
 
     Cost of revenues for 1995 was $44.2 million compared to $35.2 million for
1994. Included in cost of revenues for 1995 were accelerated amortization and
write-offs of capitalized game software development costs of $16.6 million and
inventory write-downs of $12.6 million primarily relating to Jaguar products. As
a result of these charges and lower selling prices for Jaguar products and
provisions for returns and allowances and price protection, gross margin for the
year was a loss of $29.6 million. For 1994, gross margin was $3.5 million, or
9.2% of revenues. Included in cost of revenues for 1994 were write-downs of
inventory of $3.6 million and amortization and the write-off of capitalized game
software development costs of $1.5 million. As of December 31, 1995, Atari had
approximately 100,000 units of the Jaguar console in inventory and there can be
no assurance that substantial additional write-downs will not be necessary.
 
     Research and development expenses for 1995 were $5.4 million compared to
$5.8 million for 1994. During 1995 and 1994, a significant number of Atari
employees and consultants were devoted to developing hardware and software for
the Jaguar, and Atari contracted with third-party software developers to develop
Jaguar software titles. As a result of Jaguar's poor sales performance, in the
third and fourth quarters of 1995, Atari accelerated its amortization of
contracted software development which resulted in charges in those quarters of
$6.0 million and $10.6 million, respectively. At December 31, 1995 and 1994,
Atari had capitalized software development costs of $758,000 and $5.1 million,
respectively. In the fourth quarter of 1995, Atari eliminated its internal
Jaguar development teams and other development staff as titles for Jaguar were
completed. As a result, Atari expects research and development expenses will be
substantially lower for the foreseeable future.*
 
     Marketing and distribution expenses for 1995 were $12.7 million compared to
$14.7 million for 1994. Such costs included television and print media,
promotions and other activities to promote Jaguar. Due to the substantial
curtailment of the Jaguar marketing program, Atari expects these expenses will
be substantially lower for the foreseeable future.*
 
     General and administrative expenses for 1995 were $5.9 million compared to
$7.2 million for 1994. The decrease in such expenses was primarily a result of
staff reductions, reduced legal fees and other operating costs. Due to the
substantial reduction in general and administrative personnel in 1995 and the
first quarter of 1996, Atari expects these expenses will be substantially lower
for the foreseeable future.*
 
     Atari experienced a gain on foreign currency exchange of $13,000 for 1995
compared to a gain of $1.2 million for 1994. These changes were a result of
lower foreign asset exposure and a greater percentage of sales made in U.S.
dollars which further reduced exposure to foreign currency transaction
fluctuations.
 
     In 1994, Atari received $2.2 million in connection with the settlement of
litigation between Atari, Atari Games Corporation and Nintendo. In 1994, Atari
also reached an agreement with Sega, which resulted in a gain of $29.8 million,
after contingent legal fees, and the sale of 4,705,883 shares of Atari Common
Stock to Sega at $8.50 per share for an aggregate of $40.0 million.
 
     During 1995, Atari sold a portion of its holdings in Dixon PLC, a retailer
in England, and realized a gain of $2.4 million, of which $1.8 million was
realized in the fourth quarter of 1995. In the first quarter of 1996, Atari sold
the remaining portion of its holdings and realized a gain of $6.1 million. The
1995 gain of $2.4 million together with other income items resulted in a total
other income of $2.7 million compared to $484,000 for 1994.

* This statement is a forward-looking statement reflecting current expectations.
  Actual results could differ materially from those projected in the
  forward-looking statement due to numerous factors, including those set forth
  in "Risk Factors -- Risk Factors Related to the Business of Atari" and

<PAGE>   82
 
     For each of 1995 and 1994, interest expense was approximately $2.3 million
on the Atari Debentures. In 1995, Atari repurchased a portion of the Atari
Debentures and realized a gain of $582,000. As of December 31, 1995, the
outstanding balance of these debentures was $42.4 million.
 
     Interest income for 1995 and 1994 was $3.1 million and $2.0 million,
respectively. The increase in interest income was primarily attributable to
higher average cash balances in 1995.
 
     As a result of Atari's operating losses, there was no provision for income
taxes in 1995. See Note 11 to the Atari Consolidated Financial Statements.
 
     As a result of the factors discussed above, Atari reported a net loss for
1995 of $49.6 million compared to net income of $9.4 million in 1994.
 
YEAR ENDED DECEMBER 31, 1994 COMPARED TO YEAR ENDED DECEMBER 31, 1993
 
     Total revenues for 1994 were $38.7 million compared to $29.1 million for
1993. The increased revenues were primarily a result of Atari's national rollout
of the Jaguar and related products. Sales of Jaguar products represented 76% of
revenues in 1994 compared to 13% of revenues in 1993. Jaguar was introduced in
selected markets in late 1993, and approximately 100,000 units were sold by the
end of 1994 at a suggested retail price of $249.99. Sales of Atari's proprietary
personal computers and certain discontinued video game products represented 24%
of revenues for 1994 compared to 87% of revenues for 1993.
 
     Gross margin for 1994 was $3.5 million, or 9.2% of revenues, compared to a
gross loss of $13.7 million for 1993. Included in cost of revenues are inventory
write-downs of $3.6 million and $18.1 million for 1994 and 1993, respectively,
and a write-off of capitalized game software development costs of $804,000 in
1994. These write-downs of proprietary personal computers and video game
products to estimated realizable values were made concurrently with the
introduction and change in marketing focus to Jaguar products.
 
     Research and development expenses for 1994 were $5.8 million compared to
$4.9 million for 1993. The increase resulted from increased expenditures for the
Jaguar product line.
 
     Marketing and distribution expenses for 1994 were $14.7 million compared to
$9.0 million for 1993. The increase in expenditures was primarily the result of
the national rollout in 1994 of the Jaguar. Such costs included television and
print media promotions and other activities.
 
     General and administrative expenses for 1994 were $7.2 million compared to
$7.6 million for 1993. The marginally lower general and administrative expenses
were primarily due to Atari's restructuring program in 1993. During 1993, Atari
made provisions for restructuring totaling $12.4 million, which included closing
many of Atari's operations in Europe, Asia and Australia, including, but not
limited to, severance payments, rental commitments and other closure costs.
 
     For 1994, Atari experienced a gain on foreign currency exchange of $1.2
million compared to a loss on exchange of $2.2 million in 1993. This change was
a result of fluctuation in exchange rates, a lower foreign asset exposure and a
greater percentage of sales made in U.S. dollars, thereby further reducing
exposure to foreign currency transaction fluctuations.
 
     For each of 1994 and 1993, interest expense was approximately $2.3 million
on the Atari Debentures.
 
     Atari utilized net operating loss carryforwards and, as a result, there was
no provision for income taxes in 1994.
 
     As a result of the factors discussed above, Atari reported net income for
1994 of $9.4 million compared to a net loss of $48.9 million in 1993.
 
QUARTER ENDED MARCH 31, 1996 COMPARED TO QUARTER ENDED MARCH 31, 1995
 
     Total revenues for the first quarter of 1996 were $1.3 million compared to
$4.9 million for the first quarter 1995, a reduction of $3.6 million. Sales of
Jaguar and related products represented 41% and 72% of total revenues for the
first quarter of 1996 and 1995, respectively, and sales of other products and
royalties represented the balance of revenues in each such year. The reduction
in revenues was primarily the result of lower unit volumes of Jaguar products
and lower average selling prices of Jaguar and certain of its software
 
                                       78
<PAGE>   83
 
titles. As a result of the Jaguar price reductions and the substantial
curtailment of sales and marketing activities for Jaguar, Atari expects sales of
Jaguar and related products to decline substantially in 1996 and thereafter.
 
     Cost of revenues for the first quarter of 1996 was $1.2 million compared to
$3.8 million for the first quarter of 1995. The reduction in cost of revenues is
consistent with the reduction in revenues.
 
     In the first quarter of 1996, the Company wrote-down inventory by $5.0
million relating to Jaguar products. These write-downs resulted from
management's revised estimates of sales resulting from continued disappointing
sales of Jaguar. Despite the introduction of four additional game titles in the
first quarter of 1996, sales of Jaguar and related products have remained
disappointing due to uncertainty about Atari's commitment to the Jaguar
platform, increased price competition and pending competitive product
introductions. Atari is pursuing alternative sales channels and licensing
opportunities. Atari expects the market to remain highly competitive throughout
the year.
 
     Research and development expenses were $200,000 for the first quarter of
1996 compared to $1.8 million for the first quarter of 1995. The substantial
decline is due to the elimination of the Company's internal Jaguar development
team and other development staff in the fourth quarter of 1995. As of March 31,
1996, Atari had capitalized $900,000 of development cost associated with certain
CD titles.
 
     Marketing and distribution expenses were $800,000 for the first quarter of
1996 compared to $2.6 million for the first quarter of 1995. The reduction was
due to the curtailment of marketing activities for the Jaguar.
 
     General and administrative expenses for the first quarter of 1996, were
$1.3 million compared to $1.8 million for the first quarter of 1995. The
decrease in such expenses was primarily the result of staff reductions, reduced
rent and other reductions in operating costs.
 
     Other Income (Expense), net for the first quarter of 1996 was $290,000
compared to $200,000 for the first quarter of 1995. Gains on sales of marketable
securities were $6.3 million for the first quarter of 1996 compared to $107,000
for the first quarter of 1995. The 1996 gain represented the sale of the
remaining portion of Atari's holdings in Dixon PLC, a retailer in England.
During the 1995 quarter Atari repurchased a portion of its 5 1/4% Convertible
Subordinated Debentures and recorded an extraordinary credit of $47,250.
 
     Interest income for the first quarter of 1996 was $300,000 compared to $1.0
million for the first quarter of 1995, reflecting Atari's significantly lower
cash balances during the first quarter of 1996. Interest expenses for the 1996
and 1995 quarters were $600,000 which represents interest due on Atari's 5 1/4%
Convertible Subordinated Debentures. In April 1996, Atari made an annual payment
of interest on its bonds that totaled $2.2 million.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     At December 31, 1995, Atari held cash and marketable securities of $50.6
million compared to $81.0 million at December 31, 1994. The decrease in cash and
marketable securities was primarily the result of operating losses incurred
during 1995.
 
     During 1995, Atari sold a portion of its holding in Dixon PLC., a U.K.
retailer, and realized a gain on the sale of these securities in the amount of
$2.4 million. In the first quarter of 1996, Atari sold its remaining interest in
Dixon PLC. and realized a gain of $6.3 million. As of December 31, 1995, Atari's
balance sheet reflected an unrealized gain on marketable securities of $7.1
million.
 
     As of March 31, 1996 , Atari held cash and marketable securities of $23.7
million compared to $50.6 million as of December 31, 1995 for a reduction of
$26.9 million.
 
     In connection with the Merger, on February 13, 1996, Atari extended a
bridge loan to JTS in the amount of $25.0 million. In event the Merger is not
consummated, the bridge loan can be converted into shares of JTS Series A
Preferred Stock at the option of Atari or JTS, subject to certain conditions.
See "The Proposed Merger and Related Transactions -- Related
Transactions -- Atari Loan to JTS."

     As of March 31, 1996, Atari had $42.4 million of its 5 1/4% convertible
subordinated debentures due April 29, 2002 outstanding. The market value of the
Atari Debentures was approximately $31.0 million at May 29, 1996. The Atari
Debentures may be redeemed at Atari's option, upon payment of a premium. The
debentures, at the option of the holders, are convertible into Atari Common
Stock at $16.3125 per share. A default with respect to other indebtedness of
Atari in an aggregate amount exceeding $5 million would result in an event of
default whereby the Atari Debentures would be due and payable immediately.
 
     Atari believes its existing cash balances are sufficient to meet its
requirements at least for the next 12 months.*

                     INFORMATION REGARDING JTS CORPORATION
 
BUSINESS OF JTS
 
     JTS was founded as a Delaware corporation in February 1994 to design,
manufacture and market hard disk drives for use in notebook computers and
desktop personal computers. JTS has developed two product families of hard disk
drives: the Nordic product family for notebook computers, which includes disk
drives with 3-inch form factors and two or three recording disks; and the
Palladium product family for desktop personal computers, which includes disk
drives with 3.5-inch form factors and two or three recording disks. JTS is also
developing a family of 5.25-inch form factor disk drives for the desktop
personal computer market. JTS markets and sells its products to original
equipment manufacturers ("OEMs") for incorporation into their notebook and
desktop computer systems and subsystems. JTS acquired several technical
personnel and rights to certain key technology utilized in JTS' disk drives in
connection with bankruptcy proceedings involving Kalok Corporation in February
1994. All JTS disk drives are currently manufactured at JTS' subsidiary, Moduler
Electronics, located in Madras, India.
 
INDUSTRY BACKGROUND
 
     The hard disk drive industry is intensely competitive and dominated by a
small number of large companies, including Quantum, Seagate, Western Digital and
Maxtor. In addition, a number of computer companies, such as Hewlett-Packard,
Toshiba and IBM, have in-house or "captive" disk drive manufacturing operations
that produce disk drives for incorporation into their own computers as well as
for sale to other OEMs. In 1995, the top six disk drive vendors accounted for
approximately 88% of the unit market share.
 
     In 1995, approximately 89 million hard disk drives were shipped,
representing a 30% increase over the prior year. Approximately 70 million, or
77%, of the hard disk drives shipped in 1995 were sold as part of desktop
personal computers, and approximately 11 million, or 12%, were sold as part of
notebook computers. In 1995, Seagate, Quantum and Western Digital controlled
approximately 61% of the desktop hard disk drive market share, and IBM and
Toshiba controlled approximately 70% of the notebook hard disk drive market
share.
 
     All hard disk drives used in notebook and desktop personal computers
incorporate the same basic technology. One or more rigid disks are attached to a
spin motor assembly which rotates the disks at a constant speed within a sealed,
contamination-free enclosure. Typically, both surfaces of each disk are coated
with a thin layer of magnetic material. Magnetic heads record and retrieve data
from discrete magnetic domains located on pre-formatted concentric tracks in the
magnetic layers of the rotating disks. An actuator positions the head over the
proper track upon instructions from the drive's electronic circuitry. Most disk
drives are "intelligent" disk drives which incorporate an embedded ASIC
controller to manage communications with the computer.
 
     The size of a hard disk drive is referred to as the drive's "form factor"
or "footprint." At present, the vast majority of personal desktop and notebook
computers incorporate disk drives with either 3.5-inch or 2.5-inch form factors.
The size of the form factor determines the size of the recording disk and,
hence, dictates the recording capacity of the disk drive. Disk drives with
smaller form factors must incorporate more disks and, as a result, more heads to
offer the same recording capacity as larger form factor drives. Therefore,
because heads and disks are the most expensive components in the hard disk
drive, larger form factor disk drives are relatively less expensive to
manufacture than smaller form factor drives with comparable recording
capacities. As a result, 3.5-inch drives are better suited for desktop personal
computers, which are not subject to the size constraints of notebook computers.
In contrast, 2.5 inch drives, because of their reduced size as well as power
conservation features and lightweight design, presently dominate the notebook
computer market.
 
     In recent years, the computer industry has witnessed the emergence of
several trends that JTS believes will continue to drive demand for innovative
disk drive products. First, new data- and image-intensive applications are
generating increased demand for greater storage capacity and performance at a
lower cost for both business and home computer users. JTS believes that this
trend will continue as more applications are developed that enable individuals
to easily access, store and manipulate digital information and as computers
 
                                       84
<PAGE>   89
 
become a more common home appliance. At the same time, a significant percentage
of personal computing is occurring on mobile devices, such as notebook
computers, which represented approximately 15% of all personal computers sold in
1995. Third, the personal computer industry is migrating towards lower profile
computing devices, both in the desktop and notebook arenas. The pressure to
shrink the dimensions, increase the capacities and lower the costs of personal
computers has presented manufacturers, especially notebook designers, with a
substantial and ongoing technical challenge.
 
JTS STRATEGY
 
     JTS' objective is to become a leading supplier of hard disk drives to the
notebook and desktop computer markets. JTS' strategy to achieve this objective
includes the following key elements:
 
          - Establish 3-inch form factor technology for notebook computers. JTS
     has developed a family of 3-inch form factor disk drives, the Nordic
     product family, for use in notebook computers as an alternative to 2.5-inch
     drives, the current industry standard. JTS Nordic disk drives are similar
     to 2.5-inch drives in terms of weight and power consumption but have a
     modestly larger footprint, although the low-profile design of the 3-inch
     drive results in its total volume being the same as the 2.5-inch drive. The
     disks used in JTS' 3-inch drives have 82% greater recording surface area
     per drive than disks used in 2.5-inch drives, and, therefore, greater
     storage capacities can be achieved at the same areal densities (megabytes
     per square inch) as 2.5-inch drives. JTS began shipment of Nordic drives in
     the second calendar quarter of 1996. Nordic drives are expected to be
     offered at prices that are competitive with the prices of 2.5-inch drives.*
 
          - Develop innovative disk drives for desktop personal computers. JTS
     has developed a 3.5-inch family of disk drives, the Palladium family, for
     desktop personal computers. Like the Nordic family of disk drives, the
     Palladium family is characterized by a low-profile, fully-encapsulated
     design and a simplified, highly-integrated platform approach. JTS began
     volume production and shipment of Palladium drives in September 1995 and is
     presently shipping Palladium drives with capacities of 1.0 and 1.6
     gigabytes. JTS is also developing a family of 5.25-inch form factor disk
     drives for the desktop market with many of the same design features as JTS'
     Nordic and Palladium drives, but with significantly greater recording
     capacities.
 
          - Achieve low product cost structure. All of JTS' manufacturing
     operations and some of its design operations take place in Madras, India,
     which offers a low-cost and well-trained labor force. In order to
     capitalize upon the low-cost labor base in India, JTS has adopted a
     manufacturing strategy of selective vertical integration. For example, JTS
     is presently vertically integrated in the manufacture of particularly
     labor-intensive components such as head stacks. JTS' disk drive products
     also share a significant amount of common componentry, thereby reducing
     manufacturing and development costs.
 
          - Form strategic alliances with key participants in the computer
     industry. JTS has entered into a Development Agreement and Purchase
     Agreement with Compaq pursuant to which Compaq has agreed to design at
     least one of JTS' disk drives into Compaq's products and to purchase a
     minimum number of disk drives subject to certain conditions. JTS intends to
     establish similar arrangements with other major computer OEMs and notebook
     computer manufacturers. In addition, JTS has entered into a Technology
     Transfer and License Agreement with Western Digital, which provides for the
     cross-licensing of JTS' and Western Digital's 3-inch disk drive technology
     and licenses Western Digital to act as a second source of 3-inch drives to
     Compaq.

PRODUCTS
 
     JTS' disk drives are characterized by the following design features:
 
          - Low Profile Design. JTS' hard disk drives have a lower profile than
     competing hard disk drives with comparable form factors and recording
     capacities. The low profile design is accomplished by a high level of
     electronic integration that allows for the printed circuit board assembly
     ("PCBA") to be placed in a small corner of the drive in the same plane as
     the recording disks (this design is known as "board in the plane of the
     media" packaging). Most competing drives place the PCBA under the drive
     mechanics which significantly increases the height of the drive.
 
          - Simplified and Highly-Integrated Platform Approach. JTS' product
     families share a simplified, highly-integrated platform approach
     characterized by a reduced number of components. JTS believes that its
     PCBAs have the fewest components in the industry because of a
     highly-integrated ASIC controller. JTS believes this simplified platform
     approach combined with common technology among its product families
     facilitates the introduction of new technology and utilizes research
     personnel in a more efficient manner, thereby reducing development costs.
 
          - Fully-Encapsulated Design. JTS disk drives are fully-encapsulated
     with no exposed PCBA and contain either a standard fixed drive connector or
     optional multi-insertion connector. The encapsulated design eliminates the
     possibility of damage to the PCBA due to electrostatic discharge and
     improves the electromagnetic interference immunity of the drive.
 
          - Common Componentry. The Nordic and Palladium product families share
     a substantial percentage of common electronic componentry which facilitates
     the simultaneous development of products for the notebook and desktop
     computer markets and reduces time to market for JTS products. For example,
     JTS' product families share spindle motors, certain head stack components
     and controller ASICs.
 
     Nordic Product Family
 
     JTS' Nordic product family is designed for notebook computers. Nordic
drives measure 90mm wide, the same width as a floppy diskette, and are
classified as 3-inch drives. The Nordic drives incorporate low-profile
architecture, measuring 10.5mm high for the two disk version and 12.5mm for the
three disk version. Nordic drive capacities presently range from 640 to 810
megabytes for the two disk version and 1.2 gigabytes for the three disk version.
The 10.5mm and 12.5mm Nordic drives are significantly thinner than the 17mm or
19mm high 2.5-inch drives, while the surface area of the recording disk in a
Nordic drive is 82% greater than a 2.5-inch disk. The greater surface area of
the disk media used in the Nordic drives allows for greater recording capacity
using the same areal densities. At the same time, the Nordic drives consume
approximately the same amount of power as 2.5-inch drives, making them well
suited for battery operated applications.
 
     The Nordic product family is being developed in conjunction with Western
Digital, which has entered into a Technology Transfer and License Agreement with
JTS obligating Western Digital to make milestone payments and to share
advancements in 3-inch technology and licensing Western Digital to serve as a
second source of Nordic products to Compaq. In addition, JTS has entered into a
Development Agreement with Compaq which committed Compaq to partially fund
Nordic development costs and obligated Compaq to purchase a minimum number of
disk drives over a two year period. Shipments to Compaq of Nordic disk drives
commenced in the second calendar quarter of 1996. Volume shipments of Nordic
drives to Compaq are expected to commence in the third quarter of fiscal 1997.*

     Palladium Product Family
 
     Palladium disk drives are 3.5-inch form factor drives designed for desktop
personal computers. The Palladium product family includes two and three disk
versions with capacities presently ranging from 540 megabytes to 1.6 gigabytes.
The Palladium drives incorporate low-profile architecture similar to Nordic
drives, measuring 1/2-inch in height compared to competing drives that typically
measure 1-inch in height. The low profile design allows two disk drives to be
configured into the same space required for one competing 3.5-inch drive. JTS
began volume production and shipments of Palladium drives in September 1995.
 
     5.25-inch Family of Hard Disk Drives
 
     JTS is developing a family of 5.25-inch form factor hard disk drives for
desktop personal computers. The 5.25-inch drives will initially include three
disks and have a capacity of 3.5 gigabytes. The 5.25-inch drives are being
designed to meet the increased data storage demands of advanced multimedia
applications. Like the Nordic and Palladium drives, the 5.25-inch drives will
have a low-profile, fully-encapsulated design and a simplified,
highly-integrated platform approach. JTS expects to begin volume production and
shipment of 5.25-inch drives in the fourth quarter of fiscal 1997.*
 
RELATIONSHIP WITH COMPAQ
 
     In June 1994, JTS entered into a Development Agreement with Compaq pursuant
to which the two companies established a plan for the development of JTS' Nordic
family of disk drives. Pursuant to the terms of the Development Agreement,
Compaq has paid $500,000 to JTS for product development expenses. In addition,
JTS has granted to Compaq certain pricing preferences and agreed to pay
royalties to Compaq on sales of Nordic disk drives to third parties during the
term of the agreement. Compaq has been granted a license to use the Nordic
designs to manufacture Nordic drives on a royalty-free basis in the event JTS
fails to meet the agreed upon production schedule. The Development Agreement
also restricts JTS' ability to sublicense Nordic technology. The Development
Agreement has a five year term, which will automatically be renewed under
certain circumstances and may be terminated by either party only with cause. JTS
and Compaq have also entered into a Purchase Agreement related to future
purchases by Compaq of Nordic drives. See "-- Patents and Licenses."
 
WESTERN DIGITAL ARRANGEMENT
 
     In February 1995, JTS entered into a Technology Transfer and License
Agreement with Western Digital. Under the terms of the agreement, Western
Digital obtained manufacturing and marketing rights to JTS' 3-inch hard disk
drive products. In return, Western Digital is obligated to make payments to JTS
totalling $6.0 million upon the achievement of certain development milestones
and is licensed to act as a second source of Nordic drives to Compaq. As of
January 28, 1996, Western Digital had made milestone payments to JTS in an
aggregate amount of $5.3 million. In February 1995, Western Digital also made a
$4.1 million equity investment in JTS as part of the transaction. The parties
have reciprocal, royalty-free, cross-license agreements for future 3-inch drive
developments, and Western Digital has granted to JTS licenses on existing
patents covering its 3-inch disk drive technology. Under certain circumstances,
the Technology Transfer and License Agreement restricts JTS from sublicensing
Nordic technology until 1998. See "-- Patents and Licenses."
 
MANUFACTURING
 
     JTS' manufacturing strategy is to be a low-cost producer of hard disk
drives for the notebook and desktop personal computer markets. All of JTS'
manufacturing operations are currently conducted at its subsidiary,

Moduler Electronics, located in Madras, India, which JTS acquired in April 1996.
See "JTS' Acquisition of the Disk Drive Division of Moduler Electronics." As of
April 26, 1996, 1,760 individuals were employed at Moduler Electronics. The
Madras facility presently occupies 85,000 square feet in a single building,
4,000 square feet of which are designated a "clean room" environment. At this
facility, JTS is adding production lines and expanding its clean room
environment. JTS believes that locating its manufacturing operations in India is
an important element of its low-cost manufacturing strategy due to the
availability of a high-quality, low-cost technical labor pool. In 1995, JTS was
granted a five year "tax holiday" with respect to sales of JTS' products in and
outside of India. In addition, Moduler Electronics is located in the Madras
export processing zone and, therefore, enjoys a tax exemption with respect to
profits generated from sales outside of India. Such exemption may be terminated
at any time, in which event JTS would become subject to significantly greater
taxes on sales of disk drives outside of India. Other benefits associated with
conducting business in India, which historically has experienced considerable
political instability, are subject to the vagaries of the Indian government, and
may be withdrawn at any time.
 
     The manufacture of high-capacity hard disk drives is a complex process,
requiring a "clean room" environment, the assembly of precision components
within narrow tolerances and extensive testing to ensure reliability. JTS'
manufacturing process is performed in three stages: subassembly, final assembly
and final test. The subassembly group builds mechanical subassemblies and flex
cables and modifies PCBAs. Printed circuit board assembly is performed by
outside vendors. The final assembly group assembles all subassemblies and
components into the mechanical head/disk assembly ("HDA"), writes servo
information, and performs preliminary testing. To avoid contamination by dust
and other particles which may impair the functioning of the disk drive, most
assembly takes place under controlled "clean room" conditions. The final test
group connects PCBAs to HDAs, burns-in completed drives and performs final
tests.
 
     The principal components used in JTS' manufacturing process are disks,
heads and PCBAs. JTS has two qualified sources for PCBAs and is in the process
of qualifying second sources for disks and heads. JTS' Indian subsidiary imports
approximately 85% of the componentry used in the manufacture of its disk drives
from outside of India. In the past, JTS has experienced delays in obtaining
certain integrated circuits required in the assembly of PCBAs, and there can be
no assurance that such delays, or difficulties in obtaining those or other
components, will not occur in the future. JTS' inability to obtain essential
components or to qualify additional sources as necessary, if prolonged, could
have a material adverse effect on JTS' business, operating results and financial
condition. In the second quarter of 1996, JTS was advised that its sole supplier
of certain head stack components intends to decrease production and ultimately
discontinue manufacturing of such components, and, therefore, JTS will be
required to secure a new supply arrangement with another manufacturer of such
components.
 
     JTS has developed a comprehensive quality assurance program. All
significant electrical and mechanical parts received from outside sources are
inspected or tested, normally on a sample basis, and testing and burn-in of
certain components and subassemblies occurs during assembly. In addition, JTS
performs several in-process quality checks and inspections, both in the PCBA and
HDA processes, and a final drive-level quality check prior to packaging.
Additional performance and reliability testing is done on a sample basis from
each week's production units in order to monitor quality levels and provide
corrective action to the factory processes. JTS generally warrants its products
against defects in design, materials and workmanship for three years. JTS
maintains in-house service facilities for refurbishment or repair of its
products in Madras, India.
 
     Due to the common componentry of the Nordic and Palladium disk drives, JTS
believes that it enjoys considerable flexibility in managing inventory levels
and meeting its customers' production requirements. In addition, JTS believes
that common componentry reduces the amount of scrap materials generated in the
manufacturing process and facilitates the training of operators in producing new
products, thus reducing production costs.
 
     JTS' longer-term manufacturing strategy calls for selective vertical
integration to reduce JTS' manufacturing costs. At present, JTS is vertically
integrated in certain labor intensive components, such as head stacks, thereby
capitalizing on the low-cost labor base in India. JTS also believes that its
proprietary controller ASIC is less expensive and more easily upgradeable than
commercially available integrated circuits.

RESEARCH AND DEVELOPMENT
 
     JTS operates in an industry characterized by rapid technological change and
short product life cycles. As a result, JTS' success will depend upon its
ability to develop new products, successfully introduce these products to the
market and ramp up production to meet customer demand. Accordingly, JTS is
committed to timely development of new products and the continuing evaluation of
new technologies. JTS' research and development efforts are presently
concentrated on broadening its existing 3.5- and 3-inch product lines and
introducing new generations of products with increased capacity and improved
performance at a lower cost. In this regard, JTS is presently designing various
high performance features, such as MR heads, new ASIC/channel technology and
advanced head lifters, into each of its hard disk drive product families. In
June 1996, JTS entered into a Heads of Agreement with Headway Corporation
("Headway"), a joint venture between Hewlett-Packard and Komag Corporation,
pursuant to which Headway has agreed to act as the exclusive supplier of MR
heads for JTS' future products.
 
     JTS expects to begin shipment of Palladium drives with recording capacities
of up to 2.5 gigabytes and Nordic drives with recording capacities of up to 2.0
gigabytes in the fourth quarter of fiscal 1997.* In addition, JTS is developing
a family of 5.25-inch disk drives for the desktop personal computer market. JTS
expects to begin shipment of 5.25-inch drives in the fourth quarter of fiscal
1997.* For the fiscal years ended January 31, 1995 and 1996, JTS' research and
development expenses totalled approximately $3.7 million and $13.4 million,
respectively. As of January 28, 1996, JTS employed 137 individuals in
engineering support and research and development.
 
SALES AND MARKETING
 
     JTS sells its products through its direct sales force operating in the
United States, Europe and Asia. In addition, JTS' hard disk drives are sold into
the Latin American markets by FutureTech International, Inc. ("Futuretech"), a
products distributor. JTS presently has a sales office in Taiwan that employs
three individuals. The Taiwan sales office markets the JTS Nordic disk drives to
local notebook computer manufacturers and works closely with the manufacturers
to design JTS' disk drives into their products. In addition, JTS has independent
sales representatives located in Japan, Germany and South Africa who market JTS'
Nordic disk drives to notebook computer manufacturers. JTS employs two sales
representatives in the United States who market JTS' 3.5-inch disk drives to
OEMs. International sales accounted for 81% of revenues in fiscal 1996. See
"Notes to JTS Financial Statements."
 
     A limited number of customers account for a significant percentage of JTS'
total revenue. In fiscal 1996, Olidata S.p.A., Connexe Peripherals, Ltd., Liuski
International, Inc. and Aashima Technology, B.V. accounted for 34%, 12%, 11% and
10%, respectively, of JTS' total revenue. In the quarter ended April 28, 1996,
Peacock Systems GmbH, Markvision International S.A. and FutureTech accounted for
43%, 18% and 14%, respectively, of JTS' total revenue. JTS expects that sales to
a relatively small number of OEMs will account for a substantial portion of its
net revenues for the foreseeable future, although the companies that comprise
JTS' largest customers may change from period to period. In particular, based on
existing contracts with FutureTech and Compaq, JTS expects that revenues from
these companies will account for a substantial percentage of JTS' revenues in
the foreseeable future. The loss of, or decline in orders from, one or more of
JTS' key customers would have a material adverse effect on JTS' business,
operating results and financial condition.
 
PATENTS AND LICENSES
 
     JTS holds no patents and has licensed in a substantial portion of the
technology used in its hard disk drives pursuant to license agreements with Pont
Peripherals Corporation, formerly DZU Corporation ("Pont"), TEAC Corporation
("TEAC") and Western Digital. If such license agreements were prematurely

terminated or if JTS were enjoined from relying upon such licenses due to JTS'
alleged or actual breach of such agreements, JTS would be prevented from
manufacturing disk drives incorporating technology subject to such licenses. As
a result, JTS' business, operating results and financial condition would be
materially adversely affected. JTS has filed three United States patents
applications. Although JTS believes that patent protection could offer
significant value, the rapidly changing technology of the computer industry
makes JTS' future success dependent primarily upon the technical competence and
creative skills of its personnel rather than on patent protection.
 
     A license with respect to certain key technology employed in JTS' Nordic
disk drives was granted to JTS by TEAC pursuant to a license agreement dated
February 4, 1994 (the "TEAC Agreement"). The TEAC Agreement also includes a
cross-license with respect to Nordic technology developed jointly by TEAC and
JTS, which will be owned jointly by the two companies, and granted certain
rights to TEAC with respect to Nordic technology developed independently by JTS,
which will be owned solely by JTS. Under the TEAC Agreement, JTS is obligated
under certain circumstances to make royalty payments to TEAC in connection with
the sale of future generation disk drives incorporating Nordic technology that
is jointly developed by JTS and TEAC or independently developed by TEAC. JTS is
not obligated to make royalty payments with respect to developments to Nordic
technology made independently by JTS, but JTS is obligated to license such
developments to TEAC on a royalty-free basis. The TEAC Agreement restricts JTS'
ability to sublicense certain technology licensed to JTS. TEAC originally
acquired its rights in certain Nordic disk drive technology pursuant to the
Agreed Order Compromising Controversies dated February 4, 1994 (the "Order")
governing the distribution of the assets of Kalok Corporation. The Order imposes
certain restrictions on JTS' right to sublicense, manufacture and sell certain
disk drive technology of Kalok Corporation that was transferred to both TEAC and
Pont pursuant to the Order.
 
     In June 1994, JTS entered into a Development Agreement with Compaq which
imposes certain restrictions on JTS' ability to sublicense Nordic technology to
third parties. In addition, the Development Agreement imposes a royalty
obligation upon JTS with respect to the sale of Nordic disk drives to third
parties during the term of the agreement. Moreover, Compaq has a right of first
refusal with respect to all production of Nordic drives until June 1997 and a
right of first refusal to license and/or acquire future JTS technologies and
products during the term of the agreement. JTS has also granted certain
non-exclusive manufacturing and marketing rights with respect to certain Nordic
technology and developments thereto within the term of the Development
Agreement. See "-- Relationship with Compaq."
 
     In January 1995, JTS and Pont entered into a cross-licensing agreement (the
"Pont Agreement") pursuant to which JTS granted to Pont a royalty-free,
nonexclusive, perpetual license to use certain JTS and jointly-developed hard
disk drive technology, to make developments to such technology and to
manufacture and sell in certain territories hard disk drives incorporating such
technology. In return, Pont granted to JTS a royalty-free, nonexclusive,
perpetual license to use certain Pont and jointly-developed hard disk drive
technology, to make developments to such technology and to manufacture and sell
in certain territories hard disk drives incorporating such technology. In
addition, Pont was obligated to make certain royalty payments to JTS for a
limited period of time with respect to the sale of hard disk drives
incorporating certain JTS technology.
 
     In February 1995, the TEAC Agreement, the Order, the Pont Agreement and the
Compaq Development Agreement were each amended to permit the license and
sublicense by JTS to Western Digital of certain rights in Nordic disk drive
technology. In addition, the amendment to the TEAC Agreement provides that JTS
will pay certain royalties to TEAC, under certain circumstances, upon the sale
of Nordic drives for a limited period of time. The Pont Agreement was also
amended to expand the territories in which JTS may manufacture and sell hard
disk drives incorporating technology subject to the agreement. JTS and Western
Digital concurrently entered into a Technology Transfer and License Agreement
pursuant to which Western Digital obtained certain manufacturing and marketing
rights to Nordic disk drive technology. The parties have reciprocal,
royalty-free, cross-license agreements for future Nordic technology
developments, and Western Digital has granted to JTS licenses on existing
patents covering its 3-inch hard disk drive technology. See "-- Western Digital
Arrangement."

COMPETITION
 
     The hard disk drive industry is intensely competitive and dominated by a
small number of large companies, including Quantum, Seagate, Western Digital and
Maxtor. In addition, a number of computer companies, such as Hewlett-Packard,
Toshiba and IBM, have in-house or "captive" disk drive manufacturing operations
that produce disk drives for incorporation into their own computers as well as
for sale to other OEMs. JTS believes that competition in the disk drive industry
is based primarily upon time to market, product availability, performance,
product capacity and price. JTS believes that it competes favorably with respect
to each of these factors. Many of JTS' competitors have broader product lines
than JTS, and all have significantly greater financial, technical and marketing
resources. There can be no assurance that JTS will be able to develop and
manufacture products on a timely basis with the quality and features necessary
in order to be competitive. High volume disk drive users typically utilize from
two to four suppliers but desire to limit the number of sources. As a result, it
may be necessary for JTS to displace competitors in many circumstances in order
to increase its net sales. In addition, JTS faces competition from the
manufacturing operations of its current and potential OEM customers, which could
initiate or increase internal production and reduce or cease purchasing from
independent disk drive suppliers such as JTS. Moreover, the hard disk drive
industry is characterized by intense price competition. If other disk
manufacturers add significant capacity or demand for disk drives decreases, the
resulting pricing pressures could adversely affect JTS' business, operating
results and financial condition. JTS has experienced pricing pressures in the
past, and there can be no assurance that JTS will not experience increased price
competition in the future. Any increase in price competition could have a
material adverse effect on JTS' business, operating results and financial
condition. If JTS' current and prospective customers and end users were to adopt
alternative data storage products, including optical storage, flash memory and
holographic storage, JTS' business, operating results and financial condition
could be adversely affected.
 
BACKLOG
 
     JTS' sales are generally made pursuant to purchase orders that are subject
to cancellation, modification, quantity reductions or rescheduling without
significant penalties. Changes in forecasts, cancellations, rescheduling and
quantity reductions may result in excess inventory costs, inventory losses and
under-utilization of production capacity and may have a material adverse effect
on JTS' business, operating results and financial condition. As a result of the
foregoing, JTS' backlog as of any particular date may not be representative of
actual sales for any succeeding period.
 
EMPLOYEES
 
     As of April 26, 1996, JTS had 1,936 full-time employees, of whom 158 were
located in San Jose, California, 1,760 were located in Madras, India, 13 were
located in Singapore and five were located in Taipei, Taiwan. Of the full-time
employees, 1,490 are engaged in manufacturing, 12 in marketing, sales and
service, 108 in product development and 18 in administration and finance.
 
     The market for well-trained employees with disk drive industry experience
is intensely competitive. JTS believes that its future success will depend on
its ability to continue to attract and retain a team of highly motivated and
skilled individuals. None of JTS' employees is represented by a labor
organization. JTS believes that its employee relations are good.
 
PROPERTIES
 
     JTS presently leases facilities in San Jose, California, Madras, India,
Singapore and Taipei, Taiwan. JTS' executive and administrative headquarters are
located in a 52,000 square foot building in San Jose. The lease on this facility
expires in July 2000, and has an option to renew for four years, subject to
certain restrictions.
 
     The Madras facility comprises approximately 85,000 square feet and is used
for all of JTS' manufacturing operations. JTS does not presently lease the
Madras facility, but rather occupies the facility pursuant to allotment letters
from the Development Commissioner of the Madras Export Processing Zone. Such
allotment letters authorize JTS to occupy the premises indefinitely so long as
the space is used in the
 
                                       91
<PAGE>   96
 
reasonable conduct of JTS' business and rents are paid in a timely fashion. JTS
currently intends to increase the size of the Madras facility by 65,000 square
feet by the end of fiscal 1997.*
 
     The Singapore office comprises approximately 1,500 square feet and is used
for JTS' purchasing operations in Southeast Asia. The lease for this facility
expires in October 1997.
 
     The Taiwan sales office has approximately 1,144 square feet and is used for
JTS' marketing and sales operations in Taiwan. The lease for this facility
expires in July 1997.
 
LEGAL PROCEEDINGS
 
     JTS has been served with a complaint filed in the Superior Court of the
State of California in and for the County of Santa Clara by Venture Lending &
Leasing, Inc. ("VLLI") relating to the relocation of certain leased equipment
from its initial location to Madras, India, in alleged violation of the lease
agreement. The complaint alleges fraud, possession and breach of the lease
agreement and seeks damages of approximately $4.6 million.

   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
                               OPERATIONS OF JTS
 
     JTS was incorporated in February 1994 and remained in the development stage
until October 1995, when it began shipping hard disk drives. From October 1995
through January 1996, JTS shipped 98,000 Palladium disk drives in 540 megabyte,
850 megabyte and 1 gigabyte configurations primarily to customers in the United
States and Europe. During the second quarter of calendar year 1996, JTS began
shipment of Nordic disk drives to Compaq under a volume purchase agreement.
There can be no assurance that JTS will be successful in the production and
shipment of these products.
 
     Since its inception, JTS has incurred significant losses which have
resulted from the substantial costs associated with the design, development and
marketing of new products, the establishment of manufacturing operations and the
development of a supplier base. JTS' ability to achieve successful operations
will depend upon a number of factors, including market acceptance of JTS'
products, the introduction of new products in a timely and cost-effective
manner, and the volume production of disk drives at acceptable manufacturing
yields. In addition, JTS will need significant additional financing resources
over the next several years for facilities expansion, capital expenditures,
working capital, research and development and vendor tooling. There can be no
assurance that JTS will achieve successful operations.
 
     All of JTS' products are manufactured in Madras, India by its Moduler
Electronics subsidiary. In March 1995, JTS entered into a verbal agreement to
acquire Moduler Electronics and subsequently assumed operational and management
control of certain aspects of Moduler Electronics' disk drive business. In April
1996, JTS acquired 90% of Moduler Electronics and, accordingly, the Pro Forma
Combined Condensed Financial Statements of JTS and Moduler Electronics are the
bases for the following discussion and analysis.
 
PRO FORMA YEAR ENDED JANUARY 28, 1996 COMPARED TO YEAR ENDED JANUARY 29, 1995
 
     For the fiscal year ended January 28, 1996, JTS' pro forma results reflect
a net loss of $35.2 million, compared to a net loss of $4.8 million for JTS in
fiscal 1995.
 
     Total pro forma revenues for fiscal 1996 were $18.8 million and consisted
of product sales and license revenues. Net product sales for fiscal 1996 were
$13.5 million as JTS initiated product shipments to customers in October 1995.
License revenues for fiscal 1996 were $5.3 million as JTS achieved certain
development milestones under its Technology Transfer and License Agreement with
Western Digital which was executed in February 1995. Of total revenues, 81% were
derived from European customers and 19% were derived from customers in the
United States. During fiscal 1996, JTS' product sales were concentrated among
several key customers with Olidata Spa, Connexe Peripherals, Ltd., Liuski
International, Inc. and Aashima Technology B.V. accounting for 34%, 12%, 11% and
10% of total product sales, respectively. JTS had no revenues in fiscal 1995.
 
     Pro forma gross margin for fiscal 1996 was a deficit of $14.8 million. The
deficit resulted principally from costs and expenses due to low manufacturing
yields and high per unit costs associated with the start-up of manufacturing
operations. Cost of product sales for fiscal 1996 also included a $4.3 million
provision for inventory allowances. The principal reasons for these allowances
include approximately $3.6 million for obsolete and unsaleable inventory,
approximately $345,000 for the costs of repairing defective products and a
reserve of approximately $500,000 for various other allowances. JTS anticipates
incurring future inventory allowances, the level of which will depend upon a
number of factors including manufacturing yields, new product introductions,
maturity or obsolescence of product designs, inventory levels and competitive
pressures.*
 
     The hard disk drive industry has been characterized by ongoing rapid price
erosion and resulting pressure on gross margins. JTS expects that hard disk
drive prices will continue to decline in the future and that

  in this Joint Proxy Statement/Prospectus.

competitors will offer products which meet or exceed the performance
capabilities of JTS products. Due to such pricing pressures, JTS' future gross
margin will be substantially dependent upon its ability to control manufacturing
costs, improve manufacturing yields and introduce new products on a timely
basis.*
 
     Research and development expenses for fiscal 1996 were $13.4 million
compared to $3.7 million for fiscal 1995. The increase is primarily attributable
to salaries and benefits resulting from the significant increase in staffing
required for product design and the development of manufacturing processes.
Specifically, during fiscal 1996, the number of employees in research and
development increased by 112 to a total of 137 employees at the end of fiscal
1996. In addition, expenses for supplies, materials and other costs associated
with design and pilot production of new products were approximately $5.0 million
in fiscal 1996 compared to approximately $1.5 million in fiscal 1995. JTS
expects that research and development expenses will continue to increase
throughout fiscal 1997 in absolute dollars but that such expenses will decline
as a percent of sales.*
 
     Selling, general and administrative expenses for fiscal 1996 were $5.8
million compared to $1.5 million for fiscal 1995. The major components of these
expenses are salaries and benefits of administrative and marketing and sales
employees, facility costs and professional fees. The growth in these expenses in
fiscal 1996 was required to support the expansion of JTS' operations and the
commencement of marketing and sales efforts. Included in 1996 is a non-cash
charge of $930,000 of amortization of deferred compensation related to the
issuance of common stock to certain officers (see Note 7 to JTS Financial
Statements). JTS expects that selling, general and administrative expenses will
increase throughout fiscal 1997 in absolute dollars but that such expenses will
decline as a percentage of sales.*
 
QUARTER ENDED APRIL 28, 1996 COMPARED TO QUARTER ENDED APRIL 30, 1995
 
     Revenue for the first quarter of fiscal 1997 was $17.6 million compared to
$2.0 million for the first quarter of fiscal 1996. Revenue for the current
quarter was comprised primarily of sales of the Company's 850 megabyte and 1
gigabyte Palladium 3 1/2-inch disk drives. Minimal product revenues were
recorded in the first quarter of fiscal 1996, as the Company initiated volume
shipments of disk drives in October 1995. However, JTS earned $2.0 million of
technology license revenue during the first quarter of fiscal 1997 as a result
of achieving certain development milestones under the Technology Transfer and
License Agreement with Western Digital. JTS' management expects revenues from
its 850 megabyte drives to be nominal for the rest of the fiscal year and sales
from its 1 gigabyte products to decline in the near future.* JTS recently began
shipment of its 1.6 gigabyte drives, the sales of which are expected to increase
in the near future.* During the second fiscal quarter, the Company will begin
shipment of Nordic 3-inch disk drives to Compaq Computer Corporation under a
volume purchase agreement.* There can be no assurance that product sales will
materialize as expected.
 
     The gross margin for the first quarter of fiscal 1997 was a deficit of $1.8
million compared to a margin of $2.0 million for the first quarter in fiscal
1996. The $3.8 million increase in the gross margin deficit is attributable to
high unit costs associated with the ramp-up of volume production of disk drives.
In order for JTS to realize positive gross margins in the future, the Company
will have to control manufacturing costs, further improve manufacturing yields
and successfully introduce new products on a timely basis.
 
     Research and development expenses were $7.4 million for the first quarter
of fiscal year 1997 compared to $1.7 million for the first quarter of fiscal
year 1996 as a result of a significant increase in the number of employees in
research and development required to meet demand for timely product design. JTS
expects that research and development expenses will continue to increase
throughout fiscal 1997 in absolute dollars but that such expenses will decline
as a percentage of sales.
 
     Selling, general and administrative expenses for the first quarter of
fiscal 1997 were $3.1 million compared to $700,000 for the first quarter of
fiscal 1996. The increase resulted from the expansion of JTS' operations and the
commencement of marketing and sales efforts. Also included is a non-cash charge
of

$330,000 related to the amortization of deferred compensation. JTS expects that
selling, general and administrative expenses will increase throughout fiscal
1997 in absolute dollars but that such expenses will decline as a percentage of
sales.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     As of January 28, 1996, JTS had cash and cash equivalents of $1.4 million.
Of this amount, $380,000 on deposit in India was restricted for use by JTS for a
90 day period beginning on January 28, 1996. On a pro-forma basis, at January
28, 1996, JTS had a working capital deficit of $17.9 million, which included
short term borrowings of $10.4 million. The short term borrowings were used to
finance working capital requirements, and included $4.3 million outstanding
under a bank line of credit and $6.1 million outstanding under bank lines of
credit in India.
 
     Since inception, JTS has acquired approximately $11.0 million in capital
equipment, furniture and fixtures and leasehold improvements. Long term debt
associated with capital acquisitions amounted to approximately $7.9 million at
January 28, 1996. JTS currently expects that approximately $22 million will be
required during calendar year 1996 for capital equipment, tooling and leasehold
improvements, primarily in India.* As of January 28, 1996, JTS had no material
commitments related to such expenditures.
 
     On February 13, 1996, Atari loaned $25.0 million to JTS pursuant to a
Subordinated Secured Convertible Promissory Note (the "Note") which is secured
by substantially all of the assets of JTS. Interest accrues on the unpaid
principal amount of the Note at the rate of 8.5% per annum. The Note provides
that JTS shall repay the outstanding principal and interest under the Note on
September 30, 1996 if the Merger has not occurred prior to such time. In the
event that the Merger Agreement is terminated, either party may, under certain
conditions, elect to convert the outstanding indebtedness under the Note into
shares of JTS Series A Preferred Stock. The Note is expressly subordinated to
outstanding indebtedness in connection with JTS' primary bank loan agreement, up
to an amount of $5.0 million at any one time. In addition, at January 28, 1996,
JTS had approximately $400,000 of unused lines of credit and approximately
$600,000 of letter of credit facilities available from three banks in India. In
March 1996, Moduler Electronics received approval from another Indian bank for a
$10 million term loan to finance capital equipment purchases. See "The Proposed
Merger and Related Transactions -- Related Transactions -- Atari Loan to JTS."
 
     Since its inception, JTS has incurred significant losses which have
resulted from the substantial costs associated with the design, development and
marketing of new products, the establishment of manufacturing operations and the
development of a supplier base. At January 28, 1996, JTS had a working capital
deficit of $17.9 million and a negative net worth of $38.4 million. JTS has yet
to generate significant revenues and cannot assure that any level of future
revenues will be attained or that JTS will achieve or maintain successful
operations in the future. Such factors have raised substantial doubt about the
ability of JTS to continue its operations without achieving successful future
operations or obtaining financing to meet its working capital needs, neither of
which can be assured. The report of independent public accountants on JTS'
financial statements includes an explanatory paragraph describing uncertainties
concerning the ability of JTS to continue as a going concern. See "Notes to JTS
Financial Statements." JTS believes that it will be able to fund operations for
the next 12 months from a combination of funds made available as a result of the
Merger, funds available under its credit facilities, cash flow from operations
and existing cash balances.*
 
     At April 28, 1996, JTS' consolidated balance sheets reflected cash and cash
equivalents of $5.1 million compared to $1.4 million at January 28, 1996. Of the
$5.1 million, approximately $400,000 on deposit in Indian banks was restricted
for use by JTS until certain obligations related to letters of credit are
settled. JTS had a working capital deficit of $31.2 million at quarter end,
which included short term borrowings from Atari of $25 million and $10.3 million
outstanding under bank lines of credit.

     The hard disk drive business is extremely capital intensive, and JTS
anticipates that it will need significant additional financing resources in the
near term for facilities expansion, capital expenditures, working capital,
research and development and vendor tooling. In this regard, JTS has held
discussions with investment banking firms regarding the possibility of raising
additional capital through the issuance of debt or equity securities. In June
1996, JTS retained an investment banking firm to advise JTS with respect to the
private issuance of between $50-100 million of 10-year debt securities
convertible into JTS Common Stock, although the terms of such financing have not
been established and the marketing effort for such financing has not yet
commenced. Recent comparable transactions were priced to yield between 5.5-6.5%
annually and included conversion premiums over the market prices of the Common
Stock of between 20-25%. JTS intends for such financing to close as soon as
practicable after the closing of the Merger and the terms of the debt securities
and the amount of the securities offered will not be determined until the
closing of the financing, if any. There can be no assurance that JTS will be
able to consummate such financing on terms acceptable to JTS or at all. As a
result, the pro forma financial statements included in this Joint Proxy
Statement/ Prospectus do not reflect such transactions. The issuance of equity
or convertible debt securities, upon conversion, would result in dilution of the
voting control of existing stockholders, could result in dilution to earnings
per share and would provide to the holders of convertible debt securities
seniority over the holders of JTS Common Stock issued in the Merger. There can
be no assurance that additional funding will be available on terms acceptable to
JTS or at all. The failure to fund its capital requirements with additional
financing would have a material adverse effect on JTS' business, operating
results and financial condition. Furthermore, certain equipment and receivables
financing as well as term loans made to JTS and Moduler Electronics are
contingent on JTS' ability to comply with stringent financial covenants. In this
regard, Moduler Electronics did not obtain certain debt and equity capital
required under one of its loan agreements. JTS has informed the lender that it
intends to provide such capital by August 1996. In addition, certain of Moduler
Electronics' loan agreements require the lender's consent to mergers and similar
transactions, which could be interpreted to require the consent of the lending
institution to the acquisition of 90% of the capital stock of Moduler
Electronics by JTS. Such consents were not obtained, but the lending institution
has continued to transact business with Moduler Electronics and JTS since JTS'
share acquisition in Moduler Electronics. JTS believes that such matters
regarding the Moduler Electronics loan agreements will not have a material
adverse effect on JTS' business, operating results or financial condition. There
can be no assurance that JTS will be able to maintain its current financing
facilities or obtain additional financing as needed on acceptable terms or at
all. If JTS is unable to obtain sufficient capital, it would be required to
curtail its facilities expansion, capital expenditures, working capital,
research and development and vendor tooling expenditures, which would materially
adversely affect JTS' business, operating results and financial condition.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
     During fiscal 1996, JTS had no Compensation Committee. Each of the members
of the JTS Board of Directors during fiscal 1996 participated in deliberations
concerning executive officer compensation. David T. Mitchell, a member of JTS'
Board of Directors, has served as Chief Executive Officer and President of JTS
since May 1995. Mr. Sirjang L. Tandon, Chairman of JTS' Board of Directors,
served as Chief Executive Officer and President of JTS from February 1994 to May
1995.
 
DIRECTOR COMPENSATION
 
     The members of JTS' Board of Directors do not currently receive any cash
compensation from JTS for their services as members of the Board of Directors or
any committee thereof. Roger W. Johnson, a director of JTS, provides consulting
services to JTS pursuant to a two-year agreement which compensates Mr. Johnson
in the amount of $2,000 per month. Mr. Johnson's consulting agreement expires in
April 1998.
 
     In March 1996, the JTS Board adopted the 1996 Non-Employee Directors' Stock
Option Plan (the "Directors' Plan") to provide for the automatic grant of
options to purchase shares of JTS Common Stock to non-employee directors of JTS
("Non-Employee Directors"). The maximum number of shares of JTS Common Stock
that may be issued pursuant to options granted under the Directors' Plan is
500,000. Pursuant to the terms of the Directors' Plan, each Non-Employee
Director (other than a compensated Chairman of the Board and any former Atari
director appointed to the JTS Board of Directors in connection with the Merger)
who is elected to the JTS Board for the first time after adoption of the
Directors' Plan and each other Non-Employee Director (other than a compensated
Chairman of the Board) who is reelected to the JTS Board at or after the 1998
stockholders' meeting will automatically be granted an option to purchase 50,000
shares of Common Stock on the date of his or her election or reelection to the
Board. Thereafter, each Non-Employee Director (other than a compensated Chairman
of the Board) will automatically be granted an option to purchase an additional
50,000 shares of Common Stock under the Directors' Plan on the date any and all
previous options or stock purchases by such person either under the Directors'
Plan or otherwise become fully vested, as discussed below. Neither directors of
JTS serving on the date the Directors' Plan was adopted nor former directors of
Atari appointed to the JTS Board in connection with the Merger have received
option grants under the Directors' Plan or will receive any such grants in
connection with the Merger, and such individuals are not eligible to receive
such grants until the 1998 stockholders' meeting.
 
     Outstanding options under the Directors' Plan will vest in two equal annual
installments measured from the date of grant. The exercise price of options
granted under the Directors' Plan shall equal the fair market value of the
Common Stock on the date of grant. No option granted under the Directors' Plan
may be exercised after the expiration of ten years from the date of grant.
Options granted under the Directors' Plan are generally non-transferable. The
Directors' Plan will terminate in March 2006, unless earlier terminated by the
Board.
 
     In the event of the dissolution, liquidation or sale of substantially all
of the assets of JTS, a specified form of merger, consolidation or
reorganization involving JTS or an acquisition transaction resulting in the
change of control of the voting power of JTS' voting securities, options
outstanding under the Plan will automatically become fully vested and will
terminate if not exercised prior to such event.

EMPLOYMENT AGREEMENT
 
     In June 1995, Kenneth D. Wing, Executive Vice President, Research &
Development Quality/Reliability of JTS, entered into an employment agreement
with JTS which provides for an annual base salary of $225,000, eligibility for
annual bonuses and a severance package that, under certain circumstances,
provides that Mr. Wing will continue to receive his base salary until June 1997
in the event he is terminated prior to such time. In addition, the employment
agreement provides for a $160,000 loan which was forgiven as to 50% of principal
and interest accrued thereon in January 1996 and shall be forgiven as to the
remainder in January 1997, provided Mr. Wing's employment with JTS continues
through such time.
 
STOCK OPTION PLAN
 
     In April 1996, JTS amended and restated its 1995 Stock Option Plan (the
"1995 Plan"), which was adopted in March 1995. Under the 1995 Plan, as amended
and restated (the "Restated Plan"), an aggregate of 9,000,000 shares of JTS
Common Stock have been reserved for issuance upon exercise of options granted to
employees, officers and directors of and consultants to JTS. As of June 18,
1996, options to purchase 3,937,313 shares of JTS Common Stock had been granted
under the Restated Plan. The Restated Plan will terminate in February 2006,
unless sooner terminated by the Board of Directors of JTS.
 
     The Restated Plan provides for the grant of both incentive stock options
intended to qualify as such under Section 422 of the Code and nonstatutory stock
options. The Board of Directors has determined that, following the Merger, the
Compensation Committee will administer the Restated Plan. The Board of Directors
has also established a Non-Officer Stock Option Committee, consisting of David
T. Mitchell, JTS' President, Chief Executive Officer and a director, with
authority to grant stock options to persons who are not at the time of the grant
of the options subject to Section 16 of the Exchange Act. As used herein with
respect to the Restated Plan, the JTS Board refers to the Compensation
Committee, the Non-Officer Stock Option Committee as well as to the Board of
Directors of JTS. The JTS Board has the authority to select the persons to whom
grants are to be made, to designate the number of shares to be covered by each
option, to establish vesting schedules, to specify the type of consideration to
be paid upon exercise and, subject to certain restrictions, to specify other
terms of the options. The maximum term of options granted under the Restated
Plan is ten years. Options granted under the Restated Plan generally are
nontransferable and generally expire three months after the termination of an
optionee's employment, directorship or consulting relationship with JTS. In
general, if an optionee becomes permanently disabled or dies while employed or
retained by JTS, such person's options generally may be exercised up to 12
months after his or her disability and generally up to 18 months after his or
her death.
 
     The exercise price of incentive stock options granted under the Restated
Plan must equal at least the fair market value of JTS' Common Stock on the date
of grant. The exercise price of nonstatutory stock options granted under the
Restated Plan must equal at least 85% of the fair market value of JTS' Common
Stock on the date of grant. The exercise price of incentive stock options
granted to any person who at the time of grant owns stock possessing more than
10% of the total combined voting power of all classes of stock must be at least
110% of the fair market value of such stock on the date of grant and the terms
of these options cannot exceed five years. Options under the Restated Plan
typically become exercisable over four years, as to one-eighth of the shares
subject to such options six months after the date of grant and as to 1/48th of
such shares each month thereafter.
 
     The Restated Plan and options outstanding thereunder will be appropriately
adjusted as to the class and the maximum number of shares subject to the
Restated Plan and the class, number of shares and price per share of stock
subject to such outstanding options in the event of stock splits, stock
dividends, recapitalizations and similar events. Under the Restated Plan, the
JTS Board of Directors has discretion in connection with a merger, consolidation
or liquidation involving JTS to provide that outstanding options shall be
terminated or shall be assumed or otherwise continued or to provide for the
accelerated vesting of outstanding options.

401(K) PLAN
 
     In January 22, 1996, JTS adopted the JTS Corporation Employee 401(k) Saving
Plan ("the 401(k) Plan") covering all of JTS' employees, except collectively
bargained employees and employees who are nonresident aliens with no United
States source income. Pursuant to the 401(k) Plan, employees may elect to reduce
their current compensation by up to the lesser of 15% of eligible compensation
or the statutorily prescribed annual limit and have the amount of such reduction
contributed to the 401(k) Plan. The 401(k) plan permits, but does not require,
matching contributions and profit sharing contributions to the Plan by JTS on
behalf of all participants. JTS has not made any such contributions to date. The
401(k) Plan is intended to qualify under Section 401 of the Code so that
contributions by employees or by JTS to the 401(k) Plan, and income earned on
plan contributions, are not taxable to employees until withdrawn, and
contributions by JTS, if any, are deductible by JTS.

(1) Under the 1995 Plan, options granted to employees vest at the rate of
    one-eighth at the end of six months and an additional 1/48 per month until
    all options have become vested at the end of four years' service. In the
    event an option was granted to an existing employee of JTS (rather than a
    newly-hired employee), such option shall vest at the rate described above
    based on the grant date of such option.
 
(2) Based on total grants of options to purchase 3,996,674 shares of JTS Common
    Stock.
 
(3) The potential realizable value is calculated based on the term of the option
    at its time of grant (10 years). It is calculated by assuming that the stock
    price on the date of grant appreciates at the indicated annual rate
    compounded annually for the entire term of the option and the option is
    exercised and sold on the last day of its term for the appreciated stock
    price. No gain to the optionee is possible unless the stock price increases
    over the option term.

LIMITATION OF LIABILITY AND INDEMNIFICATION MATTERS
 
     As permitted by the DGCL, JTS' Certificate of Incorporation provides that
no director of JTS will be personally liable to JTS or its stockholders for
monetary damages for breach of fiduciary duty as a director, except for
liability (i) for any breach of the director's duty of loyalty to JTS or to its
stockholders, (ii) for acts or omissions not made in good faith or which
involved intentional misconduct or a knowing violation of law, (iii) under
Section 174 of the DGCL, relating to prohibited dividends or distributions or
the repurchase or redemption of stock, or (iv) for any transaction from which
the director derives an improper personal benefit. In addition, JTS' Bylaws
provide that any director or executive officer who was or is a party or is
threatened to be made a party to any action or proceeding by reason of his or
her services to JTS will be indemnified to the fullest extent permitted by the
DGCL.
 
     JTS has entered into indemnification agreements with each of its directors
and executive officers under which JTS has agreed to indemnify each of them
against expenses and losses incurred for claims brought against them by reason
of their being a director or officer of JTS, and JTS maintains directors' and
officers' liability insurance.
 
     There is no pending litigation or proceeding involving a director or
officer of JTS as to which indemnification is being sought, nor is JTS aware of
any pending or threatened litigation that may result in claims for
indemnification by any director or officer.

CERTAIN TRANSACTIONS
 
     Since JTS' inception in February 1994, JTS has maintained significant
business relationships with Moduler Electronics, Tantec Magnetics, Inc., a
California corporation ("Tantec"), and Maazda Travel, Inc. ("Maazda"). Mr.
Sirjang L. Tandon, JTS' Chairman and Corporate Technical Strategist, or members
of his immediate family, directly or indirectly own controlling equity interests
in each of Moduler Electronics, Tantec and Maazda. In fiscal 1996, Moduler
Electronics provided subassembly and final assembly manufacturing services to
JTS for which JTS had made aggregate payments to Moduler Electronics of
approximately $13.0 million, and JTS has provided certain equipment on
consignment to Moduler Electronics with an aggregate value of approximately $4.4
million. Tantec has provided certain hard disk drive component parts, test
equipment and services to JTS for which JTS had made aggregate payments to
Tantec of approximately $366,000 and $295,000 in fiscal 1995 and 1996,
respectively, and JTS sold certain hard disk drives to Tantec with an aggregate
value of approximately $653,000 in fiscal 1996. During fiscal 1996, JTS made
aggregate payments to Maazda, JTS' principal travel agent, of approximately
$100,000.
 
     From February 1994 to February 1995, JTS received bridge loans aggregating
approximately $2.9 million from certain significant JTS stockholders evidenced
by secured convertible notes (the "First Financing Notes"). The First Financing
Notes accrued interest at a rate of 8.5% per annum. All of the First Financing
Notes were canceled and the principal outstanding thereunder was converted into
shares of JTS Series A Preferred Stock in connection with the JTS Series A

                 DESCRIPTION OF CAPITAL STOCK OF ATARI AND JTS
 
     The following descriptions of the capital stock of Atari and JTS are
qualified by reference to Atari's Articles of Incorporation and JTS' Certificate
of Incorporation and any amendments thereto. Copies of these are included as
exhibits to the Registration Statement of which this Joint Proxy
Statement/Prospectus is a part.
 
ATARI CAPITAL STOCK
 
     General. The authorized capital stock of Atari consists of 100,000,000
shares of Common Stock, $.01 par value per share, and 10,000,000 of undesignated
Preferred Stock, $.01 par value per share. As of close of business on June 28,
1996, 63,854,718 shares of Atari Common Stock were issued and outstanding and no
shares of Preferred Stock were issued and outstanding.
 
     At the Effective Time of the Merger, each share of Atari Common Stock
issued and outstanding immediately prior to the Effective Time will be canceled
and extinguished and be converted automatically into the right to receive one
share of JTS Common Stock.
 
     Common Stock. Holders of Atari Common Stock are entitled to one vote per
share on matters to be voted upon by the stockholders and are not entitled to
cumulative voting in the election of directors. Subject to any preferences
granted to holders of Atari Preferred Stock or of any other senior equity,
holders of Atari Common Stock are entitled to receive dividends when, as and if
declared by the Atari Board of Directors, and to share ratably in the assets of
Atari legally available for distribution to its stockholders in the event of
liquidation, dissolution and winding up of Atari. Holders of Atari Common Stock
have no preemptive, subscription, redemption or conversion rights with respect
to Atari Common Stock. All outstanding shares of Atari Common Stock are validly
issued, fully paid and nonassessable.
 
     Preferred Stock. Atari has 10,000,000 shares of undesignated preferred
stock authorized, none of which are issued and outstanding. The Atari Board of
Directors has the authority to issue the undesignated preferred stock in one or
more series and to fix the rights, preferences, privileges and restrictions
granted to or imposed upon any wholly unissued shares of undesignated preferred
stock and to fix the number of shares constituting any series and the
designations of such series, without any further vote or action by the
stockholders.
 
     Convertible Subordinated Debentures. As of March 31, 1996, Atari had $42.4
million of 5 1/4% convertible subordinated debentures due April 29, 2002
outstanding. The market value of these debentures was approximately $29.3
million at June 18, 1996. The debentures may be redeemed at Atari's option, upon
payment of a premium. The debentures, at the option of the holders, are
convertible into common stock at $16.3125 per share. At March 31, 1996,
2,596,414 shares of Atari Common Stock were reserved for issuance upon
conversion of the outstanding debentures. A default with respect to other
indebtedness of Atari in an aggregate amount exceeding $5 million would result
in an event of default whereby the outstanding debentures would be due and
payable immediately.
 
     Registrar and Transfer Agent. The registrar and transfer agent for Atari
Common Stock is the Registrar and Transfer Company.
 
JTS CAPITAL STOCK
 
     Prior to the Merger, the authorized capital stock of JTS consists of
90,000,000 shares of JTS Common Stock, $.000001 par value per share, and
70,000,000 shares of Preferred Stock, $.000001 par value per share, all of which
is designated Series A Preferred Stock.
 
     JTS is a privately held company; there is no public trading market for its
stock. As of the close of business on June 18, 1996, 9,263,866 shares of JTS
Common Stock and 29,696,370 shares of JTS Series A Preferred Stock were issued
and outstanding. There are a total of 54 holders of record of JTS Series A
Preferred Stock and 20 holders of record of JTS Common Stock.
 
     Preferred Stock Rights.  The principal rights, privileges and preferences
of the issued and outstanding shares of JTS Series A Preferred Stock are as set
forth below.
 
                                       110
<PAGE>   115
 
     Dividends.  Holders of JTS Series A Preferred Stock are entitled to
dividend preferences when, as and if declared by the JTS Board, at an annual
rate of $.09 per share. All dividends are cumulative. JTS may not pay cash
dividends on JTS Common Stock while there are any declared but unpaid cash
dividends on any shares of JTS Series A Preferred Stock.
 
     Liquidation.  In the event of any liquidation, dissolution or winding up of
JTS (which, upon the election of the holders of a majority of the Series A
Preferred Stock, would include the Merger), holders of the JTS Series A
Preferred Stock are entitled to receive, prior and in preference to any
distribution of any assets of JTS to the holders of JTS Common Stock, $1.00 per
share plus all accrued and unpaid dividends. After the holders of JTS Series A
Preferred Stock have received the full amount of their liquidation preference,
the holders of JTS Common Stock and JTS Series A Preferred Stock (on an
as-converted basis) are entitled to receive all remaining assets of JTS
available for distribution pro rata based on the number of shares of JTS Common
Stock held or, after conversion of JTS Series A Preferred Stock, that would be
held by each such holder; provided, however, if the holders of JTS Series A
Preferred Stock, exclusive of any unpaid cumulative dividends, would receive at
least an aggregate of $5.00 per share of Series A Preferred Stock, then the
holders of Series A Preferred Stock shall not be entitled to the $1.00 per share
preference over the holders of JTS Common Stock.
 
     Redemption.  Holders of JTS Series A Preferred Stock are entitled to
certain mandatory redemption rights. Upon the election of a majority of the
holders of JTS Series A Preferred Stock and provided JTS has funds legally
available to do so, JTS shall redeem one-third, one-half and the remainder of
all of the outstanding shares of Series A Preferred Stock on February 7, 2000,
February 7, 2001 and February 7, 2002, respectively.
 
     Voting Rights.  Subject to the protective provisions described above and
except as otherwise required by law, the holders of JTS Common Stock and JTS
Series A Preferred Stock are entitled to notice of any stockholders' meeting and
to vote together as a single class upon any matter submitted to the stockholders
for a vote on the following basis:
 
     (a) Common Vote.  Each share of Common Stock issued and outstanding has one
vote.
 
     (b) Preferred Vote.  Each holder of JTS Series A Preferred Stock has a
number of votes equal to the number of full shares of JTS Common Stock into
which such JTS Preferred Stock is then convertible. Each share of JTS Series A
Preferred Stock is presently convertible into one share of JTS Common Stock.
 
     Protective Provisions.  JTS must obtain the approval of at least two-thirds
of the outstanding shares of JTS Series A Preferred Stock to (i) create a new
class of stock with rights equal to or superior to the rights of Series A
Preferred Stock; (ii) sell, lease or convey all or substantially all of JTS'
property or business; (iii) amend JTS' Certificate of Incorporation if such
alters the rights of the Series A Preferred Stock; (iv) increase the authorized
number of shares of JTS Preferred or Common Stock; (v) undertake a
reorganization, merger, or consolidation in which the holders of JTS voting
stock will hold less than 50% of the voting stock of the successor entity; (vi)
pay or declare a dividend other than in Common Stock to the holders of Common
Stock; or (vii) repurchase JTS securities other than from employees or
consultants of JTS when their employment ends.
 
     All of the outstanding shares of JTS Common Stock and JTS Series A
Preferred Stock are validly issued, fully paid and nonassessable.
 
     Upon consummation of the Merger, the holders of JTS Series A Preferred
Stock will become holders of JTS Common Stock and, consequently, will no longer
be entitled to certain rights and privileges described above. In addition,
certain other rights and privileges of JTS stockholders will change as a result
of the Merger. Upon completion of the Merger, the percentage ownership of the
Combined Company by each former JTS stockholder will be significantly less than
his, her or its current percentage ownership of JTS. Accordingly, former JTS
stockholders will have a significantly smaller voting influence over the affairs
of the Combined Company than they currently enjoy over the affairs of JTS. "See
Risk Factors -- Risk Factors Related to the Business of JTS -- Reduction in
Voting Control." Moreover, certain contractual rights presently possessed by
holders of JTS Series A Preferred Stock will cease to exist after the Merger.
Finally,
 
                                       111
<PAGE>   116
 
the statutory protections available to JTS stockholders under Section 2115 of
the CGCL will no longer exist. See "Comparison of Rights of Stockholders of
Atari and JTS -- Application of the General Corporation Law of California to
Delaware Corporations."
 
CERTIFICATE OF INCORPORATION AND BYLAWS OF THE COMBINED COMPANY
 
     The authorized capital stock of the Combined Company shall consist of
150,000,000 shares of common stock, $.001 par value per share, and 10,000,000
shares of undesignated, "blank check" preferred stock, $.001 par value per
share. The Board of Directors of the Combined Company will have the authority to
issue the undesignated preferred stock in one or more series and to fix the
rights, preferences, privileges and restrictions granted to or imposed upon any
wholly unissued shares of undesignated preferred stock and to fix the number of
shares constituting any series and the designations of such series, without any
further vote or action by the stockholders.
 
     The Combined Company's Certificate of Incorporation will provide that all
stockholder actions must be effected at a duly called meeting and may not be
effected by written consent. In addition, the Combined Company's Certificate of
Incorporation and Bylaws will provide that only the Chairman of the Board of
Directors, the Chief Executive Officer or the Board of Directors pursuant to a
resolution adopted by at least two directors will be permitted to call a special
meeting of stockholders. These and other provisions, including the creation of
"blank check" preferred stock, could discourage potential acquisition proposals
and could delay or prevent a change in control of the Combined Company. These
provisions are intended to enhance the likelihood of continuity and stability in
the composition of the Board of Directors and in the policies formulated by the
Board of Directors and to discourage certain types of transactions that may
involve an actual or threatened change of control of the Combined Company. These
provisions are designed to reduce the vulnerability of the Combined Company to
an unsolicited acquisition proposal. The provisions also are intended to
discourage certain tactics that may be used in proxy fights. However, such
provisions could have the effect of discouraging others from making tender
offers for the Combined Company's shares and, as a consequence, they also may
inhibit fluctuations in the market price of the Combined Company's shares that
could result from actual or rumored takeover attempts. Such provisions also may
have the effect of preventing changes in the management of the Company. See
"Risk Factors -- Other Risk Factors Related to the Merger -- Control by
Affiliates; Anti-takeover Effects."
 
DELAWARE TAKEOVER STATUTE
 
     The Combined Company will be subject to Section 203 of the Delaware General
Corporation Law ("DGCL"), which, subject to certain exceptions, prohibits a
Delaware corporation from engaging in any business combination with any
interested stockholder for a period of three years following the time that such
stockholder became an interested stockholder, unless: (i) prior to such time,
the board of directors of the corporation approved either the business
combination or the transaction that resulted in the stockholder becoming an
interested stockholder; (ii) upon consummation of the transaction that resulted
in the stockholder becoming an interested stockholder, the interested
stockholder owned at least 85% of the voting stock of the corporation
outstanding at the time the transaction commenced, excluding for purposes of
determining the number of shares outstanding those shares owned (a) by persons
who are directors and also officers and (b) by employee stock plans in which
employee participants do not have the right to determine confidentially whether
shares held subject to the plan will be tendered in a tender or exchange offer;
or (iii) at or subsequent to such time, the business combination is approved by
the board of directors and authorized at an annual or special meeting of
stockholders, and not by written consent, by the affirmative vote of at least
66 2/3% of the outstanding voting stock that is not owned by the interested
stockholder.
 
     Section 203 defines business combination to include: (i) any merger or
consolidation involving the corporation and the interested stockholder; (ii) any
sale, transfer, pledge or other disposition of 10% or more of the assets of the
corporation involving the interested stockholder; (iii) subject to certain
exceptions, any transaction that results in the issuance or transfer by the
corporation of any stock of the corporation to the interested stockholder; (iv)
any transaction involving the corporation that has the effect of increasing the
proportionate share of the stock of any class or series of the corporation by
the interested stockholder; or
 
                                       112
<PAGE>   117
 
(v) the receipt by the interested stockholder of the benefit of any loans,
advances, guarantees, pledges or other financial benefits provided by or through
the corporation. In general, Section 203 defines an interested stockholder as
any entity or person owning 15% or more of the outstanding voting stock of the
corporation and any entity or person affiliated with or controlling or
controlled by such entity or person.
 
                      COMPARISON OF RIGHTS OF STOCKHOLDERS
                   OF ATARI AND JTS AND THE COMBINED COMPANY
 
     The rights of Atari stockholders are governed by its Articles of
Incorporation and any amendments thereto (the "Atari Articles"), Atari's Bylaws
and any amendments thereto (the "Atari Bylaws") and the laws of the State of
Nevada. The rights of JTS stockholders are governed by its Certificate of
Incorporation and any amendments thereto (the "JTS Certificate"), JTS' Bylaws
and any amendments thereto (the "JTS Bylaws") and the DGCL. After the Effective
Time, the rights of Atari and JTS stockholders who become stockholders of the
Combined Company will be governed by the Certificate and Bylaws of the Combined
Company and the DGCL.
 
APPLICATION OF THE GENERAL CORPORATION LAW OF CALIFORNIA TO DELAWARE
CORPORATIONS
 
     The discussion below primarily addresses the differences between the DGCL
and general corporation law of Nevada. However, Section 2115 of the CGCL makes
substantial portions of the CGCL applicable, with limited exceptions, to a
foreign corporation with ("Section 2115") more than half of its outstanding
stock held of record by persons having addresses in California and more than
half of its business conducted in the state (as measured by factors based on a
corporation's levels of property, payroll and sales determined for California
franchise tax purposes), irrespective of the corporation's state of
incorporation. Although JTS is incorporated in Delaware, it is subject to
Section 2115. The statutory provisions of the CGCL to which JTS is subject
include but are not limited to provisions governing a director's standard of
care in performing the duties of a director, a stockholder's right to vote
cumulatively in any election of directors, a director's or stockholder's right
to inspect corporate records, indemnification requirements concerning directors,
officers and others and the corporate requirements to effectuate corporate
reorganizations (including mergers and acquisitions). Section 2115 also invokes
the application of Chapter 13 of the CGCL to the Merger with respect to JTS
stockholders who elect to exercise dissenters' rights. Upon completion of the
Merger, the statutory protections available to JTS stockholders pursuant to
Section 2115 will no longer apply.
 
COMPARISON OF THE RIGHTS OF ATARI AND JTS STOCKHOLDERS AND STOCKHOLDERS OF THE
COMBINED COMPANY
 
     The following is a summary of material differences between the rights of
Atari and JTS stockholders under their respective charter documents, the
Combined Company's charter documents and applicable state laws.
 
     Cumulative Voting. Under Delaware and Nevada law, cumulative voting in the
election of directors is not mandatory. Elimination of cumulative voting limits
the ability of minority stockholders to obtain representation on the board of
directors. The JTS Certificate provides for cumulative voting in elections of
Directors. The Atari Articles and Bylaws do not provide for cumulative voting in
elections of Directors. The Certificate and Bylaws of the Combined Company do
not provide for cumulative voting in elections of Directors. To the extent that
Section 2115 would render California law applicable to JTS, cumulative voting in
the election of directors would be required.
 
     Power to Call Special Stockholders' Meetings; Advance Notice of Stockholder
Business and Nominees. The Atari Bylaws provide that special meetings of
stockholders may be called by the Board of Directors, the Chairman of the Board
or the President. The JTS Bylaws provide that special meetings of stockholders
may be called by the Board of Directors or a committee of the Board. The Bylaws
of the Combined Company provide that special meetings of stockholders may be
called by the Chairman of the Board of Directors, the Chief Executive Officer or
the Board of Directors pursuant to a resolution adopted by at least two
directors.
 
                                       113
<PAGE>   118
 
     Under Delaware and Nevada law, a special meeting of stockholders may be
called by the board of directors or by any other person authorized to do so in
the certificate of incorporation or the bylaws.
 
     Any limitation on the ability to call special stockholder meetings could
make it more difficult for stockholders to initiate action that is opposed by
the board of directors. Such action on the part of stockholders could include
the removal of an incumbent director, the election of a stockholder nominee as a
director or the implementation of a rule requiring stockholder ratification of
specific defensive strategies that have been adopted by the board of directors
with respect to unsolicited takeover bids.
 
     Size of the Board of Directors. Delaware and Nevada law each permit the
board of directors alone to change the authorized number, or the range, of
directors by amendment to the bylaws, unless the directors are not authorized to
amend the bylaws or the number of directors is fixed in the certificate of
incorporation (in which case a change in the number of directors may be made
only by amendment to the certificate of incorporation following approval of such
change by the stockholders). The Atari Bylaws provide for a range of directors
between five and seven, until changed by an amendment to the Atari Articles or
by stockholder vote. However, the number of directors cannot be less than five
if the votes against the action or the votes not consenting to the action are
equal or are greater than 16 2/3% of the outstanding shares. The exact number of
directors shall be fixed by the Board or by stockholder resolution. The current
number of directors on the Atari Board is six. The JTS Certificate and Bylaws
authorize the JTS Board of Directors to determine the number of directors on the
JTS Board of Directors. The current number of directors on the JTS Board is six.
The Certificate of the Combined Company provides that number of directors on the
Board of Directors of the Combined Company shall be determined exclusively by
resolutions of the Board of the Combined Company.
 
   
     Classified Board of Directors. A classified board is one to which a certain
number, but not all, of the directors are elected on a rotating basis each year.
Delaware and Nevada law permit, but do not require, a classified board of
directors, with staggered terms under which one-half or one-third of the
directors are elected for terms of two or three years, respectively. This method
of electing directors may make changes in the composition of the board of
directors, and thus a potential change in control of a corporation, a lengthier
and more difficult process. The charter documents of Atari, JTS and the Combined
Company do not provide for a classified board of directors. The establishment of
a classified board following the Merger would require the approval of the
stockholders of the Combined Company. To the extent that Section 2115 would
render California law applicable to JTS, directors must be elected annually,
unless the corporation is listed on the American Stock Exchange.
    
 
     Removal of Directors. Under Nevada law, unless the articles of
incorporation provide for cumulative voting or a larger percentage of voting
stock required to do so, any director may be removed from office by the vote of
stockholders representing not less than two-thirds of the voting power of the
class or series of stock of the corporation entitled to elect such director. The
Atari Bylaws do not provide for cumulative voting. The Atari Bylaws allow the
Board to remove any director declared of unsound mind by court order or
convicted of a felony. Otherwise, a two-thirds vote of outstanding shares is
needed to remove a director.
 
     Under Delaware law, a director of a corporation that does not have a
classified board of directors or cumulative voting may be removed with or
without cause with the approval of a majority of the outstanding shares entitled
to vote. In the case of a Delaware corporation having cumulative voting, if less
than the entire board is to be removed, a director may not be removed without
cause if the number of votes cast against such removal would be sufficient to
elect the director under cumulative voting. A director of a corporation with a
classified board of directors may be removed only for cause, unless the
certificate of incorporation otherwise provides. To the extent that Section 2115
would render California law applicable to JTS, any directors or the entire board
of directors may be removed, with or without cause, with the approval of a
majority of the outstanding shares entitled to vote; provided, however, no
director may be removed (unless the entire board is removed) if the number of
shares voted against removal would be sufficient to elect the director under
applicable cumulative voting rules. The JTS Certificate provides for cumulative
voting. The Certificate of the Combined Company does not provide for cumulative
voting. The Certificate and Bylaws of the Combined Company allow removal of a
director, subject to the rights of preferred stock holders, (i) with cause by a
majority of the outstanding shares or (ii) without cause by two-thirds of the
outstanding shares.
 
                                       114
<PAGE>   119
 
     Filling Vacancies on the Board of Directors. Under Nevada law, unless a
Corporation's articles of incorporation provide otherwise, any vacancy on the
board of directors, including one created by removal of a director or an
increase in the number of authorized directors, may be filled by the majority of
the remaining directors, even if such number constitutes less than a quorum. The
Atari Articles so provide. The Atari Bylaws also provide for vacancies filled by
directors. Stockholders may fill the vacancy if the directors fail to do so.
Under Delaware law, vacancies and newly created directorships may be filled by a
majority of the directors then in office (even though less than a quorum) unless
otherwise provided in the certificate of incorporation or bylaws (and unless the
certificate of incorporation directs that a particular class is to elect such
director, in which case any other directors elected by such class, or a sole
remaining director, shall fill such vacancy). In addition Delaware law permits a
ten percent (10%) stockholder to order an election to fill a director vacancy.
The JTS Bylaws allow a vacancy to be filled by a majority of the remaining
members of the Board of Directors, although the majority is less than a quorum
or by a plurality of stockholder votes. The Bylaws of the Combined Company
provide that a director vacancy shall only be filled by a majority of the
remaining directors, even though less than a quorum.
 
     Interested Director Transactions. Under both Nevada and Delaware law,
certain contracts or transactions in which one or more of a corporation's
directors has an interest are not void or voidable because of such interest
provided that certain conditions, such as obtaining the required approval and
fulfilling the requirements of good faith and full disclosure, are met. With
certain exceptions, the conditions are similar under Nevada and Delaware law.
Under Nevada and Delaware law, either the stockholders or the disinterested
members of the board of directors must approve any such contract or transaction
after full disclosure of the material facts, and in the case of board approval
the contract or transaction must also be fair to the corporation, or the
contract or transaction must have been just and reasonable or fair as to the
corporation at the time it was authorized or approved. If board approval is
sought, the contract or transaction must be approved by a majority vote of a
quorum of the directors, without counting the vote of any interested directors
(except that interested directors may be counted for purposes of establishing a
quorum). The JTS Bylaws reiterate Delaware corporate law regarding interested
director transactions. The Articles and Bylaws of Atari and the Certificate and
Bylaws of the Combined Company contain no special provision regarding such
transactions.
 
     Loans to Officers and Employees. Under Nevada law, any transaction
(including any loan or guaranty) to or for the benefit of a director or officer
of the corporation or its parent is permitted (unless otherwise provided for in
the corporation's articles of incorporation) provided a disinterested majority
of the board of directors or stockholders, after full and fair disclosure of the
material terms of such transaction, approve such transaction, or if such
transaction is fair to the corporation at the time it is authorized or approved.
Under Delaware law, a corporation may make loans to, guarantee the obligations
of or otherwise assist its officers or other employees and those of its
subsidiaries (including directors who are also officers or employees) when such
action, in the judgment of the directors, may reasonably be expected to benefit
the corporation. Pursuant to the Bylaws of the Combined Company and in
accordance with Delaware law, the Combined Company may make loans to, guarantee
the obligations of or otherwise assist its officers or other employees and those
of its subsidiaries (including directors who are also officers or employees)
when such action, in the judgment of the Board of the Combined Company, may
reasonably be expected to benefit the corporation. The Articles and Bylaws of
Atari and the Certificate and Bylaws of JTS contain no special provision
regarding such transactions.
 
     Indemnification and Limitation of Liability. Nevada and Delaware have
similar laws respecting indemnification by a corporation of its officers,
directors, employees and other agents. The laws of both states also permit
corporations to adopt a provision in their charters eliminating the liability of
a director to the corporation or its stockholders for monetary damages for
breach of the director's fiduciary duty of care. There are nonetheless certain
differences between the laws of the two states with respect to indemnification
and limitation of liability.
 
     Atari's Articles indemnify directors to the fullest extent permissible
under Nevada law. Atari's Bylaws further provide for indemnification for Atari's
agents and authorize the Board of Directors to purchase and maintain insurance.
Similar to Delaware law, Nevada law does not permit the elimination of monetary
liability
 
                                       115
<PAGE>   120
 
where such liability is based on intentional misconduct, fraud, knowing
violation of law or payments or distributions in violation of law. In addition,
Nevada law departs from Delaware law insofar as Nevada law (i) permits a broader
array of insurance or other financial arrangements between a company and its
directors, and (ii) allows a provision in the corporation's bylaws or articles
of incorporation which mandates indemnification rather than leaving that
decision to the board of directors.
 
     The Certificates of JTS and the Combined Company eliminate the liability of
directors and officers to the fullest extent permissible under Delaware law, as
such law exists currently or as it may be amended in the future. Under Delaware
law, such provision may not eliminate or limit director monetary liability for
(a) breaches of the director's duty of loyalty to the corporation or its
stockholders; (b) acts or omissions not in good faith or involving intentional
misconduct or knowing violations of law; (c) the payment of unlawful dividends
or unlawful stock repurchases or redemptions under DGCL Section 174; or (d)
transactions in which the director received an improper personal benefit. Such
limitation of liability provisions also may not limit a director's liability for
violation of, or otherwise relieve JTS, the Combined Company or the directors of
either of them from the necessity of complying with, federal or state securities
laws, or affect the availability of non-monetary remedies such as injunctive
relief or rescission.
 
     The Bylaws of JTS and the Combined Company state that indemnification for
JTS' or the Combined Company's agents will be as set forth in the DGCL. However,
JTS may modify the extent of such indemnification by individual contracts with
its directors and executive officers. In addition, the DGCL provides that the
indemnification provided by statute shall not be deemed exclusive of any other
rights under any bylaw, agreement, vote of stockholders or disinterested
directors or otherwise. The Bylaws of JTS and the Combined Company track this
provision of Delaware law.
 
     JTS has entered into indemnification agreements with its officers and
directors. Upon consummation of the Merger, such agreements will become binding
on the Combined Company. It is expected that the Combined Company will enter in
similar agreements with Jack Tramiel and Michael Rosenberg.
 
     Delaware law generally permits indemnification of expenses incurred in the
defense or settlement of a derivative or third-party action, provided there is a
determination by a disinterested quorum of the directors, by independent legal
counsel or by a majority vote of a quorum of the stockholders that the person
seeking indemnification acted in good faith and in a manner reasonably believed
to be in or (in contrast to Nevada law) not opposed to the best interests of the
corporation (or in the case of a criminal proceeding, if the accused had no
reasonable cause to believe the conduct was unlawful). Without court approval,
however, no indemnification may be made in respect of any derivative action in
which such person is adjudged liable for negligence or misconduct in the
performance of his duty to the corporation.
 
     The Certificate of the Combined Company limits director liability to the
Combined Company or its stockholders for monetary damages arising out of a
director's breach of his duty of care. The duty of care refers to the fiduciary
duty of a director to exercise sufficient diligence and care in considering a
transaction or causing the corporation to take or refuse to take corporate
action. The Certificate of the Combined Company, however, does not eliminate the
duty of care; it only eliminates monetary damage awards occasioned by a breach
of such duty. Thus, after the Merger, a breach of the duty of care would remain
a valid basis for a suit seeking to prevent a proposed transaction from
occurring. After the transaction has occurred, however, the stockholders would
not have a claim against directors for monetary damages based on the breach of
the duty of care, even if that breach involved gross negligence on the part of
the directors.
 
     Reorganizations, Asset Sales and Mergers. Both Nevada and Delaware law
generally require that a majority of the stockholders of the acquiring and
target corporations approve statutory mergers. Delaware law does not require a
stockholder vote of the surviving corporation in a merger (unless the
corporation provides otherwise in its certificate of incorporation) if (a) the
merger agreement does not amend the existing certificate of incorporation, (b)
each share of the surviving corporation outstanding before the merger is an
identical out standing or treasury share after the merger, and (c) the number of
shares to be issued by the surviving corporation in the merger does not exceed
20% of the shares outstanding immediately prior to the merger. Nevada law
contains a substantially similar exception to its voting requirements for the
surviving corporation in a reorganization. To the extent Section 2115 would
render California law applicable to JTS,
 
                                       116
<PAGE>   121
 
stockholder approval of each constituent corporation in a statutory merger and
any parent corporation is required, except (i) corporations which will own (or
where stockholders will own), equity securities (other than warrants) possessing
more than 5/6 of the voting power of the surviving corporation or (ii) parent
corporations, not subject to Section 2115, incorporated under the laws of other
states not requiring such approval.
 
     Both Nevada and Delaware law also require that a sale of all or
substantially all of the assets of a corporation be approved by the board of
directors and a majority of the voting shares of the corporation transferring
such assets.
 
     If required by the articles of incorporation, Nevada law requires that
mergers, reorganizations, certain sales of assets and similar transactions be
approved by a majority vote of each class of shares outstanding and/or a larger
percentage vote than a simple majority of the voting shares. The Atari Articles
do not require such approval. By contrast, Delaware law generally does not
require class voting, except in certain transactions involving an amendment to
the certificate of incorporation which adversely affects a specific class of
shares. To the extent Section 2115 would render California law applicable to
JTS, a majority vote of each class of shares outstanding and/or a larger
percentage vote than a simple majority would be required to approve certain
mergers, reorganizations, sales of assets or similar transactions. JTS'
Certificate provides for special voting rights of JTS' Series A Preferred Stock.
The following actions must be approved by at least 2/3 of holders of outstanding
JTS Series A Preferred Stock: (1) creation of a new class of stock on par or
superior in rights to the Series A Preferred Stock; (2) selling, leasing or
otherwise disposing of all or most of JTS's property; (3) an amendment of the
JTS Certificate if such amendment would alter the rights of the JTS Series A
Preferred Stock; (4) increasing the authorized number of shares of JTS Series A
Preferred or JTS Common Stock; (5) a transaction involving a reorganization,
consolidation or merger in which the holders of JTS voting stock hold less than
50% of the voting stock of the successor entity; (6) payment or declaration by
any dividend other than in Common Stock to the holders of Common Stock; or (7)
repurchase of securities other than from employees or consultants terminating
their employment or consulting relationship with JTS.
 
     Should JTS authorize and issue shares of a new class of capital stock, the
holders thereof would vote with the holders of the previously outstanding
capital stock on proposals not adversely affecting a particular class. In such
event the holders of the previously outstanding capital stock, if in the
minority, would be unable to control the outcome of a vote, and, if in the
majority, would be able to control the outcome of such a vote.
 
     Elimination of Actions by Written Consent of Stockholders. Under Nevada and
Delaware law, stockholders may execute an action by written consent in lieu of a
stockholder meeting. Nevada and Delaware law permit a corporation to eliminate
such actions by written consent in its charter or bylaws. The Bylaws of Atari
and JTS provide for action of the stockholders without a meeting including
written consent. The Certificate of the Combined Company does not permit action
by written consent of stockholders.
 
     Dividends and Repurchases of Shares. Nevada law dispenses with the concepts
of par value of shares as well as statutory definitions of capital, surplus and
the like. The concepts of par value, capital and surplus are retained under
Delaware law.
 
     Nevada law prohibits a distribution (including dividends, purchases,
redemptions or other acquisition of shares, distributions of indebtedness or
otherwise) if, after giving effect to the distribution, (1) the corporation
would not be able to pay its debts as they become due in the usual course of
business or (2) except as provided in the articles of incorporation, the
corporation's total assets would be less than the sum of its total liabilities
plus the amount that would be needed, if the corporation were to be dissolved at
the time of distribution, to satisfy the preferential rights upon dissolution of
stockholders whose preferential rights are superior to those receiving the
distribution.
 
     Delaware law permits a corporation to declare and pay dividends out of
surplus or, if there is no surplus, out of net profits for the fiscal year in
which the dividend is declared and/or for the preceding fiscal year as long as
the amount of capital of the corporation following the declaration and payment
of the dividend is not less than the aggregate amount of the capital represented
by the issued and outstanding stock of all classes having a preference upon the
distribution of assets. In addition, Delaware law generally provides that a
corporation may redeem or repurchase its shares only if such redemption or
repurchase would not impair the capital of the corporation. To the extent that
Section 2115 would render California law applicable to JTS,
 
                                       117
<PAGE>   122
 
distributions (including dividends and redemptions of shares) are permitted if
the corporation's assets-to-liabilities ratios are sufficient under CGCL Section
500.
 
     Appraisal or Dissenters' Rights. Under both Nevada and Delaware law, a
stockholder of a corporation participating in certain major corporate
transactions may, under varying circumstances, be entitled to appraisal or
dissenters' rights pursuant to which such stockholder may receive cash in the
amount of the fair market value of his or her shares in lieu of the
consideration he or she would otherwise receive in the transaction. Under
Delaware law, such dissenters' rights are not available (a) with respect to the
sale, lease or exchange of all or substantially all of the assets of a
corporation, (b) with respect to a merger or consolidation by a corporation
whose shares are either listed on a national securities exchange or are held of
record by more than 2,000 holders if such stockholders receive only shares of
the surviving corporation or shares of any other corporation which are either
listed on a national securities exchange or held of record by more than 2,000
holders, plus cash in lieu of fractional shares, or (c) to stockholders of a
corporation surviving a merger if no vote of the stockholders of the surviving
corporation is required to approve the merger because the merger agreement does
not amend the existing certificate of incorporation, each share of the surviving
corporation outstanding prior to the merger is an identical outstanding or
treasury share after the merger, and the number of shares to be issued in the
merger does not exceed 20% of the shares of the surviving corporation
outstanding immediately prior to the merger and if certain other conditions are
met. See "The Proposed Merger and Related Transactions -- Appraisal and
Dissenters' Rights -- Delaware Appraisal Rights."
 
     Under Nevada law, dissenters' rights are not available in a merger or share
exchange if the shares held by the stockholders prior to the share exchange or
merger were either listed on a national securities exchange or held by at least
2,000 stockholders of record unless the articles of incorporation of the
corporation provide otherwise or the stockholders are required to accept under
the plan of merger share exchange anything other than cash or shares of the
surviving corporation or shares that are listed on a national securities
exchange, or a combination of these. Because Atari Common Stock is listed on a
national securities exchange and because the Atari Articles do not provide
otherwise, Atari stockholders may not exercise dissenters' rights with respect
to the Merger.
 
     To the extent that Section 2115 would render California law applicable to
JTS, stockholders who dissent from a merger may also be entitled to dissenters'
rights under the CGCL. See "The Proposed Merger and Related
Transactions -- Appraisal and Dissenters' Rights -- California Dissenters'
Rights."
 
     The foregoing discussion of material differences between the rights of
Atari and JTS stockholders under their respective charter documents and
applicable state laws is only a summary of certain provisions and does not
purport to be a complete description of such differences. The discussion is
qualified in its entirety by reference to the Nevada, Delaware and California
General Corporation Laws, the respective common law in Nevada, Delaware and
California and the full text of the Certificate of Incorporation and any
amendments thereto and the Bylaws and any amendment thereto of Atari and JTS.
 
                                 LEGAL MATTERS
 
     The validity of the JTS Common Stock issuable in the Merger, the federal
income tax consequences in connection with the Merger and certain other matters
relating to the Merger will be passed upon for JTS by Cooley Godward Castro
Huddleson & Tatum. The federal income tax consequences in connection with the
Merger and certain other matters relating to the Merger will be passed upon for
Atari by Wilson Sonsini Goodrich & Rosati, P.C. As of June 18, 1996, one member
of Wilson Sonsini Goodrich & Rosati, P.C., investment partnerships of which such
individual is a partner and a trust for which such individual serves as trustee,
beneficially owned 84,000 shares of JTS Series A Preferred Stock.

                             STOCKHOLDER PROPOSALS
 
     In the event the Merger is not consummated for any reason, Atari expects to
hold an annual meeting in 1997. To be eligible for inclusion in Atari's proxy
solicitation materials for its annual stockholder meeting to be held in 1997,
any stockholder proposal to be considered at such meeting must have been
received at Atari's principal executive offices, 455 South Mathilda Avenue,
Sunnyvale, California 94086, no later than January 20, 1997. Any such proposal
is subject to the requirements of the proxy rules adopted under the Exchange
Act.

                        REPORT OF DELOITTE & TOUCHE LLP
 
To the Shareholders and Board of Directors
  of Atari Corporation:
 
     We have audited the accompanying consolidated balance sheets of Atari
Corporation and subsidiaries as of December 31, 1995 and 1994, and the related
consolidated statements of operations, shareholders' equity, and cash flows for
each of the three years in the period ended December 31, 1995. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on the financial statements based on our
audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, such consolidated financial statements present fairly, in
all material respects, the financial position of Atari Corporation and
subsidiaries at December 31, 1995 and 1994, and the results of their operations
and their cash flows for each of the three years in the period ended December
31, 1995 in conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. COMPANY
 
     Nature of Operations -- The Company designs and markets interactive
multimedia entertainment systems and related software and peripheral products.
Manufacture of these products is performed by third parties. The principal
methods of distribution are through mass market retailers, consumer electronic
specialty stores and distributors of electronic products.
 
     Product Focus -- Since 1992, the Company has focused its research and
development effort on its 64-bit Jaguar interactive multimedia entertainment
system. This product was introduced in 1993 and, in 1995 and 1994, 68% and 76%
of revenues, respectively, were associated with this product. Sales of the
Jaguar in 1995 were disappointing and the Company is currently test marketing
different price points and software bundles for the Jaguar in an attempt to sell
its substantial inventory of such products.
 
     In December 1994, the Company planned price reductions beginning in early
1995 and recognized the impact of this decision on finished and in-process
inventory through a write-down of inventory of $3.6 million, which is included
in cost of sales in the fourth quarter of 1994. In December 1995, the Company
planned further price reductions beginning in early 1996 and recognized the
impact of this decision through a $10.9 million write-down of inventory, which
is included in cost of sales in the fourth quarter of 1995.
 
     The Company continues to carry limited quantities of its older 8-bit and
16-bit video games and computer product lines. As a result of rapid
technological change and intense competition, the Company wrote down inventories
of these products by $18.1 million in 1993 which was included in cost of sales.
 
     Estimates -- The preparation of financial statements in accordance with
generally accepted accounting principles requires management to make estimates
and assumptions that affect recorded amounts of assets, liabilities, revenues
and expenses as of the dates and for the periods presented. In connection with
the change of the Company's focus, measurement of assets and liabilities is
dependent upon management's ability to accurately predict future operating
results. Actual results could differ from these estimates.
 
     Restructuring -- The Company has active operations in the United States and
the United Kingdom. During 1993 and 1992, the Company significantly restructured
its operations around the world, closing operations in Australia and the Far
East, in several European countries and in Canada and Mexico. These operational
closures resulted in the bankruptcy of subsidiaries in Australia and Germany and
may result in the voluntary or involuntary liquidation or bankruptcy of other
subsidiary companies. Charges for restructuring have been separately reported in
the consolidated statements of operations for 1993. The remaining accruals of
$351,000 at December 31, 1995 relate to employee benefits in Italy and lease
obligations in the Netherlands.
 
2. SIGNIFICANT ACCOUNTING POLICIES
 
     Principles of Consolidation -- The consolidated financial statements
include the Company and its subsidiaries. All transactions and balances between
the companies are eliminated.
 
     Cash and Equivalents -- Cash equivalents are stated at cost, which
approximates market value, have maturities not exceeding ninety days upon
acquisition and generally consist of certificates of deposit, time deposits,
treasury notes and commercial paper.
 
     Marketable Securities -- Effective January 1, 1994, the Company adopted
Statement of Financial Accounting Standards (SFAS) No. 115, "Accounting for
Certain Investments in Debt and Equity Securities." Marketable securities are
carried as available-for-sale securities and reported at the fair market value.
The cumulative effect of adoption of SFAS 115 as of January 1, 1994 was not
material. Unrealized gains and losses are reported as a separate component of
shareholders' equity. Realized gains and losses are recorded in the statements
of operations and realized gains were $2.4 million in 1995. The cost of
securities sold is based on average cost.

<PAGE>   131
 
                               ATARI CORPORATION
 
           NOTES TO CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)
 
     Inventories -- Inventories are stated at the lower of cost or market. Cost
is computed using standard costs which approximate actual cost on a first-in,
first-out basis. Market for each of the Company's product lines is determined by
reference to expected sales prices less direct selling expenses.
 
     Prepaid Advertising -- Included in other current assets at December 31,
1994 is $3.2 million of prepaid advertising resulting from a barter transaction.
The amount recorded as prepaid advertising equals the carrying value of certain
inventory exchanged for advertising credits. The Company expensed the prepaid
advertising as utilized during 1995.
 
     Equipment and Tooling -- Equipment and tooling are stated at cost.
Depreciation on equipment is computed using the straight-line method based on
estimated useful lives of the assets of two to five years. Tooling is
depreciated on a units of production basis. Leasehold improvements are amortized
over the estimated useful life or lease term, as appropriate. Fully depreciated
assets, and related depreciation, are excluded from the consolidated financial
statements.
 
     Real Estate Held for Sale -- Real property associated with closed
operations in the U.S. is stated at estimated market value as determined by
recent valuations, appraisals or pending sales offers.
 
     Revenue Recognition -- Sale of consoles, software game cartridges and
related products are recorded as revenue at the time of shipment to customers.
Concurrently, the Company establishes reserves for estimated returns, which are
recorded as a reduction of sales, and for cooperative advertising allowances,
which are recorded as marketing and distribution expense. Royalty revenues are
recognized when earned and collection is probable.
 
     Income Taxes -- The Company adopted SFAS No. 109 "Accounting for Income
Taxes" in the first quarter of 1993 which requires an asset and liability method
for financial accounting and reporting of income taxes. The impact of the
adoption of SFAS 109 was not material.
 
     Foreign Currency Translation -- Assets and liabilities of operations
outside the United States are translated into United States dollars using
current exchange rates, and the effects of foreign currency translation
adjustments are deferred and included as a component of shareholders' equity.
 
     Income (Loss) per Common Share -- Per share amounts are computed based on
the weighted average number of common and dilutive common equivalent shares
(stock options) outstanding during each period. The effect of the assumed
conversion of the 5 1/4% convertible subordinated debentures was antidilutive
for all periods presented and excluded from the computation.
 
     Fiscal Year -- The Company uses a 52/53 week fiscal year which ends on the
Saturday closest to December 31. All fiscal years presented contain 52 weeks.
For simplicity of presentation, the date December 31 is used to represent the
fiscal year end.
 
     Reclassifications -- Certain items have been reclassified in the 1994 and
1993 financial statements to conform to the 1995 presentation and had no effect
on operating results or shareholders' equity.
 
     Recently Issued Pronouncements -- In October 1995, the Financial Accounting
Standards Board issued FASB No. 123, "Accounting for Stock-Based Compensation."
The new standard defines a fair value method of accounting for stock options and
other equity instruments, such as stock purchase plans. Under this method,
compensation cost is measured based on the fair value of the stock award when
granted and is recognized as an expense over the service period, which is
usually the vesting period. This standard will be effective for the Company
beginning in 1996, and requires measurement of awards made beginning in 1995.
The new standard permits companies to continue to account for equity
transactions with employees under existing accounting rules, but requires
disclosure in a note to the financial statements of the pro forma net income and
earnings per share as if the Company had applied the new method of accounting.
The Company intends to follow these

disclosure requirements for its employee stock plans. As a result, adoption of
the new standard will not impact reported earnings or earnings per share, and
will have no effect on the Company's cash flows.

     The contractual maturities of the government securities range from two to
four years. The Eurodollar notes matured during 1995.
 
     Concentration of Credit Risk -- The Company sells to mass market retailers,
consumer electronic specialty stores and to distributors of electronic products
throughout the United States and Europe. The Company makes ongoing credit
evaluations of customers and, at times, requires letters of credit from some
foreign customers. Sales to foreign customers are generally stated in the
currency of the customer. To date, the Company has not entered into hedges of
these foreign currency exposures.
 
     Fair Value of Financial Instruments -- In accordance with the provisions of
SFAS No. 107, "Disclosure About Fair Value of Financial Instruments," which
requires the disclosure of fair value information about both on and off balance
sheet financial instruments where it is practicable to estimate the value, the
Company has estimated the fair value of its financial instruments. The estimated
fair value of the 5 1/4% convertible subordinated debentures at December 31,
1995 was approximately $20 million based primarily on quoted market prices. The
carrying amounts of the remainder of the Company's financial instruments,
including cash and equivalents, marketable securities, accounts receivable and
accounts payable, approximate fair values due to their short maturities.

amounts paid to third parties, primarily as prepaid licenses, in connection with
game development for the Jaguar. The Company amortizes such costs over the
shorter of 12 months from game introduction or the estimated unit sales of the
game title. The Company assesses the recoverability of capitalized games
software development costs in light of many factors, including, but not limited
to, anticipated future revenues, estimated economic useful lives and changes in
software and hardware technologies. Amortization expense and adjustments for
management's assessment of recoverability were $17.1 million (including a
write-off of $16.6 million) and $1.5 million (including a write-off of $804,000)
for the years ended December 31, 1995 and 1994, respectively.

10. LONG-TERM DEBT OBLIGATIONS
 
     Convertible Subordinated Debentures -- The Company has $42.4 million of
5 1/4% convertible subordinated debentures due April 29, 2002. The debentures
may be redeemed at the Company's option, upon payment of a premium. The
debentures, at the option of the holders, are convertible into common stock at
$16.3125 per share. At December 31, 1995, 2,596,414 shares of common stock were
reserved for issuance upon conversion. Default with respect to other
indebtedness of Atari Corporation in an aggregate amount exceeding $5 million
would result in an event of default whereby the outstanding debentures would be
due and payable immediately.
 
     In 1995, the Company reacquired in the open market and extinguished $1.1
million face value of these debentures for $500,000, resulting in an
extraordinary credit of $582,000.
 
     Term Loans on Real Estate in Europe -- At December 31, 1993, the Company
had two secured term loans outstanding totaling $7.5 million for its building in
Germany and a term loan of $2.0 million for its land and building in France.
These loans were repaid or exchanged in 1994 from the sale or transfer of the
properties.

     Due to the uncertainty surrounding the timing and realization of the
benefits of its favorable tax attributes in future years, the Company has
established a valuation allowance to offset its net deferred tax assets.
 
     Current federal and state tax law includes certain provisions limiting the
use of net operating loss carryforwards in the event of certain defined changes
in stock ownership. The annual use of the Company's net operating loss
carryforwards could be limited according to these provisions, and there can be
no assurance that such limitations will not result in the loss of carryforward
benefits during the carryforward period.
 
13. STOCK OPTIONS
 
     The Company's stock option plan and restricted stock plan provide for the
issuance of up to 3,000,000 shares of common stock through the issuance of
incentive stock options to employees and nonqualified stock options and
restricted stock to employees, directors and consultants. Under the plans, stock
options or restricted stock may be granted at not less than fair market value as
determined by the Board of Directors. Stock options become exercisable as
established by the Board (generally ratably over five years) and expire up to
ten years from date of grant. The Company's right to repurchase restricted stock
lapses over a maximum period of five years. At December 31, 1995, options for
551,925 shares were exercisable and options for 602,310 shares were available
for future grant. At December 31, 1995, no restricted stock under the restricted
stock plan had been issued.

     Certain claims and suits arising in the ordinary course of business have
been filed or are pending against the Company. The number of such claims has
increased as the Company significantly downsized its development operations. In
the opinion of management, all such matters have been adequately provided for,
are without merit, or are such that if settled unfavorably would not have a
material adverse effect on the Company's consolidated financial position and
results of operations.
 
16. SUBSEQUENT EVENT
 
     On February 12, 1996, the Company entered into a merger agreement with JT
Storage, Inc. (JTS) providing for the merger of the Company and JTS. On April 8,
1996, the merger agreement was amended and restated. JTS was incorporated on
February 3, 1994 to develop, market and manufacture hard disk drives. The merger
requires shareholder approval and is expected to be consummated in the second
quarter of 1996. In connection with the merger, the Company extended a bridge
loan to JTS in the amount of $25.0 million maturing on September 30, 1996 with a
stated interest rate of 8 1/2% per annum. If the merger is not consummated, the
bridge loan is convertible at the option of Atari or JTS into shares of JTS
Series A Preferred Stock and warrants to acquire JTS Series A Preferred Stock,
subject to certain conditions.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
NOTE 1.  BASIS OF PRESENTATION
 
     The financial statements included herein have been prepared by the Company,
without audit, pursuant to the rules and regulations of the Securities and
Exchange Commission. Certain information and footnote disclosures normally
included in financial statements prepared in accordance with generally accepted
accounting principles have been condensed or omitted pursuant to such rules and
regulations. However, the Company believes that the disclosures are adequate to
make the information presented not misleading. It is suggested that these
financial statements be read in conjunction with the financial statements and
notes thereto included in the Company's 1995 Annual Report on Form 10-K, filed
with the Securities and Exchange Commission.
 
     The unaudited financial statements included herein reflect all adjustments
(which include only normal, recurring adjustments), which are, in the opinion of
management, necessary to state fairly the results for the periods presented. The
results for such periods are not necessarily indicative of the results to be
expected for the full fiscal year.
 
     The Company operates with a 52/53 week fiscal calendar. Both quarters
covered by this report have 13 weeks and for simplicity of presentation, the
calendar quarter date is used to represent the quarter end. The actual fiscal
closing dates for the first quarter of 1996 and 1995 were March 30, and April 1,
respectively.
 
NOTE 2.  INVENTORIES
 
     In the first quarter of 1996, the Company wrote-down inventory by $5.0
million relating to Jaguar products. These write-downs resulted from
management's revised estimates of sales resulting from continued disappointing
sales of Jaguar.
 
     Inventories consist of the following (in thousands):

     In the first quarter of 1995, the Company repurchased a portion of its

NOTE 4.  MERGER JT STORAGE, INC.
 
     On February 12, 1996, the Company entered into a merger agreement with JT
Storage, Inc. (JTS) providing for the merger of the Company and JTS. On April 8,
1996, the merger agreement was amended and restated. JTS was incorporated on
February 3, 1994 to develop, market and manufacture hard disk drives. The merger
requires shareholder approval and is expected to be consummated in the second
quarter of 1996. In connection with the merger, the Company extended a bridge
loan to JTS in the amount of $25.0 million maturing on September 30, 1996 with a
stated interest rate of 8 1/2% per annum. If the merger is not consummated, the
bridge loan is convertible at the option of Atari or JTS into shares of JTS
Series A Preferred Stock and warrants to acquire JTS Series A Preferred Stock,
subject to certain conditions.

                         REPORT OF ARTHUR ANDERSEN LLP
 
To the Board of Directors of
  JTS Corporation:
 
     We have audited the accompanying balance sheets of JTS Corporation (a
Delaware corporation), formerly JT Storage, Inc., as of January 28, 1996 and
January 29, 1995, and the related statements of operations, stockholders'
deficit and cash flows for the year ended January 28, 1996 and the period from
inception (February 3, 1994) to January 29, 1995. These financial statements are
the responsibility of the Company's management. Our responsibility is to express
an opinion on these financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of JTS Corporation as of
January 28, 1996 and January 29, 1995, and the results of its operations and its
cash flows for the year ended January 28, 1996 and the period from inception
(February 3, 1994) to January 29, 1995, in conformity with generally accepted
accounting principles.
 
     The accompanying financial statements have been prepared assuming that the
Company will continue as a going concern. As discussed in Note 1 to the
financial statements, the Company has suffered recurring losses from operations
and has a net capital deficiency that raises substantial doubt about its ability
to continue as a going concern. Management's plans in regard to these matters
are also described in Note 1. The financial statements do not include any
adjustments that might result from the outcome of this uncertainty.

                         NOTES TO FINANCIAL STATEMENTS
 
1.  ORGANIZATION AND OPERATIONS:
 
     JTS Corporation (the "Company"), a Delaware corporation, formerly JT
Storage, Inc. (Note 12), was incorporated on February 3, 1994 to develop, market
and manufacture hard disk drives. The Company was a development stage company
prior to the commencement of production shipments in October 1995. Accordingly,
the Company ceased to be in the development stage at that time. Moduler
Electronics (India) Private Limited ("Moduler Electronics"), a company owned by
the family of a major stockholder manufactured, on a contract basis, all of the
Company's products. In April 1996, the Company acquired 90% of Moduler
Electronics (Note 10).
 
     On February 4, 1994, as part of a settlement in United States Bankruptcy
Court, the Company acquired certain assets and assumed certain liabilities of
Kalok Corporation ("Kalok") in exchange for a note payable to the Kalok
Bankruptcy estate (Note 5) and a warrant to Kalok's unsecured creditors (Note
7). Liabilities assumed of $543,172 exceeded the fair market value of assets
acquired by approximately $215,000 which, due to uncertainties regarding its
realization, was expensed in the accompanying 1995 statement of operations. In
connection with the settlement agreement, the Company acquired certain
proprietary disk drive technology from TEAC Corporation ("TEAC") in exchange for
482,850 shares of common stock, which represented 10% of the outstanding Common
Stock of the Company. No value was assigned to the acquired technology as it had
no cost basis to TEAC and the common stock was deemed to have nominal value. On
February 3, 1995, the Company agreed to issue 1,000,000 shares of Redeemable
Series A preferred stock to TEAC in exchange for the return of the 482,850
shares of common stock and the cancellation of a shareholder agreement with TEAC
(Note 8).
 
     The Company has continued to develop its technology and manufacturing
capabilities during fiscal 1996. This development has resulted in substantial
increases in accounts receivable, accounts payable, bank borrowings, and a net
working capital deficit of $15,246,000 as of January 28, 1996. Operations
subsequent to year end indicate the Company has continued to suffer losses and
its working capital deficit has continued to increase. These factors raise a
substantial doubt about the ability of the Company to continue as a going
concern. The Company's management is pursuing plans to merge with Atari
Corporation ("Atari"). In the opinion of management, the merger, if successful,
would raise cash adequate to fund operations for at least the next 12 months.
Thereafter, the Company will require additional funding. Subsequent to year end,
Atari extended a $25 million loan to the Company of which $19.7 million had been
used as of April 4, 1996. In the event the merger (Note 10) is not consummated,
the loan will, at Atari's option, either be due September 30, 1996 or converted
into the Company's preferred stock. In addition, Moduler Electronics received
approval of additional financing from another Indian bank resulting in total
unused credit facilities of approximately $12 million, subject to certain
conditions.
 
2.  ACCOUNTING POLICIES:
 
     Pervasiveness of Estimates
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from these estimates.
 
     Revenue Recognition and Product Warranty
 
     Revenue from product sales is generally recognized upon shipment to
customers. The Company warrants its products against defects in design,
materials and workmanship generally for three years. A provision for estimated
future costs relating to warranty expense is recorded when products are shipped.

</TABLE>
 
     Equipment and Leasehold Improvements
 
     Property and equipment are stated at cost and are depreciated using the
straight-line method over estimated useful lives of three years. Repairs and
maintenance costs are expensed as incurred. Major renewals and betterments which
substantially extend the useful life of the asset are capitalized.
 
     The Company had equipment with an historical cost of approximately
$4,400,000 and $530,000 located at Moduler Electronics at January 28, 1996 and
January 29, 1995, respectively.
 
     Research and Development
 
     Research and development costs are expensed as incurred and consist
primarily of salaries, materials and supplies.
 
     Income Taxes
 
     The Company follows Statement of Financial Accounting Standards No. 109,
"Accounting for Income Taxes" ("SFAS No. 109"). SFAS No. 109 requires
recognition of deferred tax assets for the expected future effects of all
deductible temporary differences, loss carryforwards and tax credit
carryforwards. Deferred tax assets are then reduced, if deemed necessary, by a
valuation allowance for the amount of any tax benefits which, more likely than
not based on current circumstances, are not expected to be realized.
 
     Cash and Cash Equivalents
 
     For purposes of the statements of cash flows, the Company considers all
highly liquid debt instruments purchased with maturities of less than three
months to be cash equivalents.
 
     Fiscal year
 
     The fiscal year of the Company is a 52- or 53-week period ending on the
Sunday closest to January 31. The fiscal year for the year ended January 28,
1996 was a 52-week period.
 
     Reclassifications
 
     Certain reclassifications have been made to prior period financial
statements to conform to the current presentation.
 
     Income from Technology License
 
     In February 1995, the Company entered into a technology transfer and
perpetual license agreement. Under this agreement, the Company granted
non-exclusive, perpetual rights to manufacture and sell certain of its products.
In connection with the agreement, the Company was obligated to achieve certain
milestones

regarding the successful completion of engineering tests, the delivery of
working models and the commencement of volume production. As of January 28, 1995
the Company had delivered a working prototype and accordingly, recognized income
of $5,275,000 in connection with achieving specified milestones in fiscal 1996.
The remaining income of $1,125,000 will be recognized as future milestones are
achieved. Funds received under this agreement are not reimbursable to the
licensee.
 
     Net Loss Per Common Share
 
     Net loss per common share is based on the weighted average number of shares
of common stock outstanding during the periods. The outstanding shares and
earnings per share have been restated for all periods presented to reflect the
impact of the stock split described in Note 7.

</TABLE>
 
     Management believes that, based on a number of factors, the available
objective evidence creates sufficient uncertainty regarding the realizability of
the net deferred tax assets such that a valuation allowance has been recorded to
completely offset the net deferred tax assets. Such factors include recurring
operating losses from inception, recent increases in expense levels to support
the Company's growth, and the fact that the market in which the Company competes
is intensely competitive and is characterized by rapidly changing technology.
 
     For income tax reporting purposes, the Company has Federal and State net
operating loss carryforwards of approximately $27,000,000 and $13,500,000,
respectively, and Federal and State research and development tax credit
carryforwards of approximately $350,000 and $250,000, respectively, all of which
will expire on various dates through 2011.
 
     The Internal Revenue Code contains provisions which may limit the amount of
tax carryforwards available to be used in any given year upon the occurrence of
certain events, including changes in ownership interests.

4.  RELATED PARTY TRANSACTIONS:
 
     Moduler Electronics Transactions
 
     As discussed in Note 1, the Company uses Moduler Electronics to manufacture
all of the Company's products. The Company purchased finished goods from Moduler
Electronics amounting to approximately $14 million in fiscal 1996 and the
majority of the accounts payable balance to Moduler Electronics at January 28,
1996 is a result of these purchases.
 
     The Company made cash advances totalling approximately $2.5 million and
also sold fixed assets and inventory totalling approximately $8.3 million to
Moduler Electronics in fiscal 1996.
 
     The advances were made to fund the manufacturing start-up of disk drives
for the Company. Because the Company intended to (and subsequently did) acquire
90% of Moduler Electronics (Note 10) and the ultimate realizability of these
advances is subject to the achievement by Moduler Electronics of successful
operations, the Company has expensed 90% of Moduler's Electronics' fiscal 1996
net loss in order to reflect its investment in Moduler Electronics' start-up
operations.
 
     The Company entered into an agreement with Moduler Electronics whereby the

7.  COMMON STOCK:
 
     Stock Split and Capitalization
 
     In February 1995, the Board of Directors approved a 4,350-for-1 common
stock split. All share and per share amounts in the accompanying financial
statements have been restated to reflect this split. In February 1996 the
Company amended its certificate of incorporation and authorized 90,000,000 and
70,000,000 shares of common and Redeemable Series A Preferred Stock,
respectively.
 
     Warrants
 
     The Company has issued warrants to purchase 100,000 shares of common stock
to the unsecured creditors of Kalok Corporation in conjunction with the
Company's acquisition of Kalok's assets. The warrants may be exercised for a
one-year period commencing on the earlier of the closing of an initial public
offering or the public registration of the Company's stock. The exercise price
of the warrant is 25% of the initial public offering price or the fair market
value of the Company's stock if the Company becomes a public registrant absent
an initial public offering. Such warrants were deemed to have nominal value at
the issuance date and, accordingly, are carried at no value in the accompanying
financial statements.
 
     The Company has also issued warrants to purchase 500,000 shares of common
stock at $1.00 and $3.00 to the equipment lease company and the bank with which
it has a line of credit, respectively. The warrants may be exercised at any time
before various dates through 2001. In the event of any acquisition, the warrant
to purchase 450,000 shares issued to the equipment lease company will terminate.
 
     Restricted Stock Purchase Agreement
 
     The Company issued 3,000,000 shares of its common stock to certain officers
in exchange for a $750,000 note receivable (Note 4). The Company has the right
to repurchase such shares at the original purchase price. However, the Company's
right to repurchase 1/48 of such shares lapses monthly. As of January 28, 1996,
2,469,271 shares were subject to repurchase. Upon issuance of the common stock
the Company recorded deferred compensation of $5,250,000 for the difference
between the per share sales price of $.25 and $2.00 (the per share fair market
value at the date of grant for financial reporting purposes). The Company is
recognizing the deferred compensation ratably over the period that the
repurchase agreement lapses. 2,000,000 of such shares, however, will no longer
be subject to repurchase in the event there are certain changes of control of
the Company. The merger (Note 10) constitutes a change of control and
accordingly, any remaining unamortized deferred compensation will be expensed at
that time.
 
     Stock Option Plan
 
     The Company has reserved 4,300,000 shares of common stock for issuance
under its 1995 Stock Option Plan. Under the plan, either incentive or
nonstatutory stock options may be granted to purchase shares of common stock.
Nonstatutory stock options may be granted to employees, nonemployee members of
the Board of Directors and consultants at prices not less than 85% of the fair
value of the stock at the date of the grant, as determined by the Board.
Incentive stock options may be granted only to employees at prices not lower
than the fair value of the stock at the date of grant, as determined by the
Board. Options granted under the plan are generally exercisable at any time, and
expire no later than ten years from the date of grant. Options granted vest at a
rate of 25% per annum.
 
     The following table presents the option activity under the Option Plan for
the period from inception to January 28,1996.

     In February and March 1996, the Company issued options to purchase 486,000
shares of common stock to various employees. Such options are ratably
exercisable ranging from $.25 to $2.95 per share and vest ratably over a four
year period.
 
     In March 1996, two officers purchased 1,000,000 shares of the Company's
Common Stock each at a purchase price of $1.00 per share. All of such shares are
subject to a right of repurchase which lapses after five years of service with
the Company provided, however, that the right of repurchase will lapse at the
rate of one-eighth in September 1996 and 1/48(th) per month thereafter if the
merger with Atari closes (Note 10).

shareholder approval and is expected to be consummated in the second quarter of

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
Company into shares of the Company's Series A preferred stock and warrants to
acquire the Company's Series A preferred stock, subject to certain conditions.
 
     Moduler Electronics
 
     In March 1995, the Company agreed to acquire the hard disk drive division
of Moduler Electronics for 1,911,673 shares of the Company's Series A preferred
stock and a warrant to purchase 500,000 shares of the Company's common stock at
an exercise price of $.25 per share. The Company subsequently assumed
operational and management control of certain portions of the hard disk drive
business of Moduler Electronics. The verbal agreement contemplated that prior to
the Company's acquisition, Moduler Electronics would divest itself of certain
voice coil assembly and other operations not directly involved in its hard disk
drive business.
 
     In April 1996, following Moduler Electronics' divestiture of its voice coil
business and businesses unrelated to its hard disk drive operations, the Company
acquired 90% of the outstanding capital stock of Moduler Electronics. Upon the
closing of the transaction, the Company acquired the stock in consideration for
1,911,673 shares of the Company's Series A preferred stock and a warrant to
purchase 750,000 shares of the Company's common stock at an exercise price of
$0.25 per share. The warrant is immediately exercisable as to 500,000 shares of
the Company's common stock and becomes exercisable with respect to the remaining
250,000 shares when there becomes available to Moduler Electronics certain
borrowings and credit facilities in the amount of $29,000,000. Subject to the
foregoing, the warrant may be exercised at any time until February 25, 2001.
 
11.  RETIREMENT SAVING PLAN
 
     In January 1996, the Company adopted the Employee 401(K) Saving Plan ("the
plan"). The plan covers substantially all of employees and allows participants
to defer a portion of their annual compensation on a pre-tax basis. The plan
permits, but does not require, additional matching contributions and profit
sharing contributions to the plan by the Company on behalf of all participants.
In fiscal 1996, the Company did not make any such contributions.
 
12.  EVENTS SUBSEQUENT TO DATE OF AUDITORS' REPORT (UNAUDITED):
 
     Change in Name
 
     On June 18, 1996, the Company changed its name to JTS Corporation from JT
Storage, Inc.
 
     Litigation
 
     The Company has been served with a complaint filed in the Superior Court of
the State of California in and for the County of Santa Clara by Venture Lending
& Leasing, Inc. ("VLLI") relating to the relocation of certain leased equipment
from its initial location to Madras, India, in alleged violation of the lease
agreement. The complaint alleges fraud, possession and breach of the lease
agreement and seeks damages of approximately $4.6 million. Such amount includes
the lease liability of $3.4 million which is recorded in the accompanying
balance sheet. The Company is currently evaluating its alternatives and the
parties have commenced preliminary settlement discussions.

NOTE 4.  MERGER WITH ATARI CORPORATION
 
     On February 12, 1996, the Company entered into a merger agreement with
Atari providing for the merger of the Company and Atari. On April 8, 1996, the
merger agreement was amended and restated. The merger required shareholder
approval and is expected to be consummated in the second quarter of 1996. In
connection with the merger, Atari extended a bridge loan to the Company in the
amount of $25.0 million maturing on September 30, 1996 with a stated interest
rate of 8 1/2% per annum. If the merger is not consummated, the bridge loan is
convertible at the option of Atari or the Company into shares of the Company's
Series A preferred stock, subject to certain conditions.

                         REPORT OF ARTHUR ANDERSEN LLP
 
To Moduler Electronics (India) Private Limited:
 
     We have audited the accompanying statements of assets and liabilities of
The Hard Disk Drive Division of Moduler Electronics (India) Private Limited as
of January 28, 1996 and January 31, 1995, and the related statements of revenues
and expenses and cash flows for the year ended January 28, 1996. These financial
statements are the responsibility of the Division's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     The financial statements referred to above have been prepared for the
purpose of complying with the rules and regulations of the Securities and
Exchange Commission (for inclusion in the joint proxy statement of Atari
Corporation and JTS Corporation, formerly JT Storage, Inc.) as described in Note
1, and are not intended to be a complete presentation of the assets,
liabilities, revenues, expenses and cash flows of Moduler Electronics (India)
Private Limited.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the assets and liabilities of The Hard Disk Drive
Division of Moduler Electronics (India) Private Limited as of January 28, 1996
and January 31, 1995, and the related revenues, expenses and cash flows for the
year ended January 28, 1996 in conformity with generally accepted accounting
principles in the United States of America.
 
     The accompanying financial statements have been prepared assuming that the
Division will continue as a going concern. As discussed in Note 1 to the
financial statements, the Division has suffered a loss from operations and has
an excess of liabilities over assets that raises substantial doubt about its
ability to continue as a going concern. Management's plans in regard to these
matters are also described in Note 1. The financial statements do not include
any adjustments that might result from the outcome of this uncertainty.

                        THE HARD DISK DRIVE DIVISION OF
                  MODULER ELECTRONICS (INDIA) PRIVATE LIMITED
                        (CURRENCY: UNITED STATES DOLLAR)
 
                         NOTES TO FINANCIAL STATEMENTS
 
1.  OPERATIONS AND BASIS OF PRESENTATION:
 
     BASIS OF STATEMENTS
 
     The accompanying statements of assets and liabilities of the Hard Disk
Drive Division ("the Division") of Moduler Electronics (India) Private Limited
("the Company") as of January 31, 1995 and January 28, 1996 and the related
statements of revenues and expenses and of cash flows for the period from
February 1, 1995 to January 28, 1996 ("the statements") have been prepared in
conformity with generally accepted accounting principles in the United States of
America, from the accounting books and records maintained by the Company at
Madras, India. The statements have been prepared for the purpose of inclusion in
the registration statement on Form S-4 to be filed by JTS Corporation ("JTS",
formerly JT Storage, Inc.) in compliance with the rules and regulations of the
Securities and Exchange Commission. The Form S-4 filing of JTS is pursuant to
its proposed acquisition of Atari Corporation ("Atari"). In April 1996, JTS
acquired 90% of the outstanding equity shares of the Company. The Division is
likely to be the only remaining business of the Company after the transfer of
the Voice Coil Magnetic Assembly ("VCMA") business to an entity owned by the
Chairman of the Company and his family members. As of April 4, 1996, this
transfer had been made, subject to completion of legal documentation.
 
     Although the Company began business in fiscal 1986, the Division first
began significant operations in fiscal 1996. Division operations prior to fiscal
1996 were insignificant; accordingly, the accompanying financial statements
include the Statements of Assets and Liabilities of the Division as of January
28, 1996 and January 31, 1995 and the related Statement of Revenues and Expenses
for the period from February 1, 1995 to January 28, 1996. These statements were
prepared from the Balance Sheet and the Income Statement, respectively, of the
total businesses of the Company, from which balances and transactions relating
to the businesses that are being divested were excluded.
 
     The Division developed its disk drive manufacturing capabilities during
fiscal 1996 which has resulted in an operating loss and a working capital
deficit of $6,459,000. In addition, the Company will require additional capital
in order to achieve volume production. The Division's disk drive production is
dedicated exclusively to JTS and JTS has recently completed its acquisition of
90% of the Division. The auditors' report on the JTS financial statements dated
April 4, 1996 contains a paragraph regarding a substantial doubt regarding the
ability of JTS to continue as a going concern. These factors raise a substantial
doubt about the Division's ability to continue as a going concern. As discussed
above, JTS plans to merge with Atari. In the opinion of management, the Atari
merger, if successful, would raise capital adequate to fund operations for the
next 12 months.
 
     Since the Company did not maintain separate accounting records for the
Division, certain estimates, which management believed to be reasonable, were
required in order to segregate the Division's account balances as of January 31,
1995 as well as to reflect the proposed divestiture of other businesses as of
January 28, 1996. The segregation of account balances relating to the Division
was made on the following bases:
 
     - Identification basis -- Account balances relating to assets, liabilities,
       revenues and expenses ("account balances") pertaining to the Division
       were specifically identified and segregated.
 
     - Agreed basis -- Account balances which have been specifically agreed to
       be assumed by the Division were identified and segregated.
 
     - Transfer basis -- Account balances pertaining to other businesses which
       were being divested, were identified and excluded.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
     - Allocation basis -- Account balances related to expenses incurred by the
       Company for the Division have been included in total as the Division was
       the significant portion of the Company's operations for fiscal 1996.
 
     INCORPORATION
 
     The Company was incorporated on March 24, 1986 as a private company under
the Indian Companies Act, 1956 in the state of Maharashtra. The Company is owned
principally by Asperal Holdings, Inc. and Dexar Holdings, Inc., companies
registered in Panama, which have a 45% equity stake each. The remaining 10% of
the Company's outstanding equity shares are owned by the Chairman of the
Company, Mr. Manohar Lal Tandon, and his relatives ("the Tandon Family").
 
     The Company was established to operate a 100 percent Export Oriented Unit
("EOU") in the Madras Export Processing Zone ("MEPZ"), a free trade zone
established by the Government of India at Madras, Tamil Nadu, India. The
Company's industrial unit is located in a government provided low cost standard
design factory within the MEPZ. The Company initially undertook the manufacture
of computer hard disk drive components such as Head Gimble Assemblies ("HGA")
and Head Stack Assemblies ("HSA"). During the first five years of operations,
the Company diversified its product line to include two other products, namely,
VCMA and Switch Mode Power Supplies ("SMPS").
 
     During fiscal 1994, the Company closed its SMPS division and established
another EOU for the assembly of hard disk drives. Under the approval obtained
from the Government of India in September 1994, the Company was originally
licensed to manufacture, on an average, 286,000 hard disk drives annually. In
November 1995, the Company obtained a revised approval to manufacture, on an
average, 807,000 hard disk drives and 418,000 subassemblies (i.e., HGAs and
HSAs) annually. In December 1994, the Company discontinued production of HGAs
and HSAs for customers other than JTS, with which it began collaborations to
manufacture hard disk drives.
 
     Though the Division started shipping nominal quantities in January 1995,
commercial production of hard disk drives commenced only in October 1995. The
Company continued to produce VCMAs until January 18, 1996 when the VCMA business
was transferred to a related party. Prior to its divestiture, a portion of the
voice coil assemblies produced by the VCMA business was used in the manufacture
of hard disk drives, while the rest were sold to a related party. Except for the
VCMA business, the Company operated as a captive manufacturer for JTS during
fiscal 1996. With its association, JTS has assumed operational and management
control of certain portions of the Division and has provided financing for the
hard disk drive business and corporate support in areas such as process
engineering, tooling, vendor selection and financial management. Since assuming
operational control, JTS has employed several expatriates consisting of disk
drive industry professionals who have filled senior positions in engineering,
manufacturing, quality control and materials management functions of the
Division.
 
     Export Oriented Unit
 
     In order to encourage export oriented businesses and foreign currency
inflows, the Government of India offers special incentives to EOUs established
in export processing zones such as state grants and subsidies, exemptions
relating to import licenses, exemptions from payment of customs duty on imported
inputs and excise duty on local material procurements, and allotment of low cost
factory space. Such EOUs are also exempted from payment of corporate income
taxes for a block of five years during the first eight years of operations,
subject to fulfillment of certain conditions. Currently, export earnings
received in convertible foreign currency continue to be exempt from tax, even
after the tax holiday period.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
     Current Operations
 
     The Division currently manufactures hard disk drives with different
capacity points, based on technical know-how and designs provided by JTS. The
Division's products are marketed through JTS under the trade names Palladium and
Nordic, and are sold to original equipment manufacturers and system integrators
who incorporate the products into desktop and notebook computers. The Division
remained in development stage until October 1995 when it first started shipping
commercial quantities.
 
     Sources of Supply
 
     Many components incorporated in, or used in the manufacture of, the
Division's products are currently sourced from a single supplier. JTS procures
components for the Division, which it purchases from third party manufacturers
and in turn sells or consigns to the Division. JTS' customers have placed
certain restrictions on vendor and design changes.
 
     The Division purchases all of its components and equipment pursuant to
purchase orders placed from time to time and has no guaranteed supply
arrangements. In the past, there have been certain instances of supply shortages
which had caused delays in manufacturing and loss of sales. Supply shortages
resulting from a change in suppliers could cause a delay in manufacturing and
possible loss of sales, which would have a material adverse impact on the
Division's operating results. Further, the Division produces in-house a number
of critical subassemblies incorporated in the final hard disk drive product.
Failure to produce these subassemblies in adequate quantity or quality could
also adversely impact the operating results of the Division.
 
     Manufacturing Relationships
 
     In the past, the Company has sold subassemblies and other components to
Xyratex in Havant, United Kingdom for the manufacture of hard disk drives under
a subcontract manufacturing agreement between Xyratex and JTS. With the
commencement of commercial production of hard disk drive products by the Company
in October 1995, the Division stopped supplying Xyratex.
 
2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:
 
     Foreign Currency Translation
 
     The Division has determined the United States ("US") dollar to be its
functional currency, in accordance with the Statement of Financial Accounting
Standards No 52, "Foreign Currency Translation", based on indicators such as
cash flows, sales market, sales price, expense, financing and inter-company
transactions and arrangements. Since the Division's books are maintained in
Indian rupees which is not its functional currency, account balances were first
remeasured in US dollar. Since the Division's functional and reporting
currencies are the same, the remeasurement process is intended to produce the
same result as if the Division's books had been maintained in the functional
currency, and obviates separate translation.
 
     Nonmonetary assets and liabilities such as inventories, plant and equipment
and accumulated depreciation thereon have been remeasured using historical
currency exchange rates prevailing at the dates transactions relating to such
elements were recognized in the statements. Expenses related to such nonmonetary
assets and liabilities such as manufacturing overhead costs included in cost of
goods sold have been remeasured using average exchange rates for the period to
approximate remeasurement at the historical exchange rates prevailing at the
dates those elements were recognized in the statements.
 
     All other monetary assets and liabilities that are not denominated in the
Division's functional currency have been translated at the current exchange
rates prevailing on the dates of the statements. Exchange gains

                  MODULER ELECTRONICS (INDIA) PRIVATE LIMITED

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
and losses from such translation of monetary assets and liabilities have been
recognized in determining net loss for the current period.
 
     Certain expenses and cash flows have been translated at average exchange
rates for the period to approximate translation at the exchange rates prevailing
at the dates those elements were recognized in the statements.
 
     Gains and losses on foreign currency transactions have been included in
determining net loss for the current period in the Statement of Revenues and
Expenses.
 
     Pervasiveness of Estimates
 
     The preparation of statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities as of the dates of the statements and the
related amounts of revenues and expenses during the reporting period. The
Company has maintained its books of accounts in accordance with Indian
accounting standards and in the local currency, the Indian rupee. As discussed
above, the Division's statements have been remeasured into US dollar in
accordance with the Statement of Financial Accounting Standards No 52. As
discussed in Note 1, certain assumptions and estimates which, management
believed to be reasonable, were required to segregate the Division's account
balances from those relating to the rest of the Company's businesses as of
January 31, 1995 and to reflect the divestiture of other businesses as of
January 28, 1996. Actual results could have been different from these estimates
and remeasurements.
 
     Revenue Recognition
 
     Revenues on product sales are recognized at the time of shipment and
include incentives provided by the Government of India on export sales.
Substantially, all shipments are sent directly to JTS' end customers, but are
invoiced by the Division to JTS, which in turn bills and collects from the end
customers.
 
     The Division's accounts receivables as of the dates of the statements
comprised of receivables outstanding from JTS arising from sale of hard disk
drives and receivables from a related party arising from sale of VCMAs. The
Company has not experienced bad debts associated with either of these customers
in the past, and accordingly, has not recorded an allowance for doubtful
accounts.
 
     Due from Other Business Units, Net
 
     As of January 31, 1995, due from other business units represent the excess
of assets over liabilities of the Company's businesses excluding the Division.
Such receivables are expected to be collected within the next twelve months.
 
     Inventories
 
     Inventories include direct materials, freight thereon, direct labor and
related manufacturing overhead costs. The Division values its inventories at
cost, determined on first in, first out ("FIFO") basis, or market value,
whichever is lower.

     Costs of normal repairs and maintenance are expensed as incurred. Major
replacements or betterments of plant and equipment are capitalized. When items
are sold or otherwise disposed of, the cost and related accumulated depreciation
are removed from the accounts and any resulting gain or loss is included in
determining net loss. The amount expensed for repairs and maintenance for the
period from February 1, 1995 to January 28, 1996 was $494,104.
 
     The Division has certain specialized manufacturing equipment used in its
operations.
 
     Income Tax
 
     Under the Indian Income Tax Act, 1961, the Division, being an EOU located
in an export processing zone, is exempted from payment of corporate income taxes
for a block of five years during the first eight years of operations, subject to
fulfillment of certain conditions.
 
     The Division continues to be exempt from income tax to the extent of income
attributable to the export sales of the Division. As the Division did not have
any taxable income for the period from February 1, 1995 to January 28, 1996, no
provision for income tax has been made.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
     Warranty Costs
 
     The Division manufactures disk drive products to customer specifications
and components for such disk drives are sourced from vendors specified by JTS.
JTS generally provides a three year limited warranty on the Palladium and Nordic
drives manufactured by the Division and has agreed to bear the costs of all
warranty claims, product returns and rework charges. Accordingly, no warranty
cost has been recorded in the Division's statements as of January 28, 1996 and
January 31, 1995.
 
     Prior to the divestiture of the Company's VCMA business, voice coil
products were manufactured and sold principally to a related party which
provided product specifications and mandated specific component sources. No
provision has been provided for any warranty costs on the voice coils sold prior
to the divestiture since the related party, to which the VCMA business is being
sold, has agreed to assume any claims related to such products.
 
     Supplemental Disclosure of Cash Flow Information
 
     For the purposes of the Statement of Cash Flows, the Division considers all
highly liquid investments purchased with original maturities of 90 days or less
to be cash equivalents. The carrying amounts reported in the statements of
assets and liabilities for cash and cash equivalents approximate their fair
values. Cash paid for interest for the period from February 1, 1995 to January
28, 1996 was $404,522. During fiscal 1996, the Company entered into capital
lease obligations amounting to $36,170. The Company also financed the purchase
of equipment amounting to $2,657,145 with secured long-term loans (Note 5).
 
     During the period from February 1, 1995 to January 28, 1996, the Division
received equipment and inventories amounting to $2,569,471 and $6,748,512,
respectively, from related parties. These were recorded as due to related
parties in the Statement of Cash Flows since they are non-cash transactions.
 
3.  RESTRICTED CASH BALANCES:
 
     Restricted cash balances comprise margin money deposits with banks
amounting to $380,013 and $197,578 as of January 28, 1996 and January 31, 1995
respectively. These deposits are maintained as security against letters of
credit issued by banks on behalf of the Division (see Note 4 below). During the
period from February 1, 1995 to January 28, 1996, rates of interest on these
deposits ranged from 9 to 12% per annum.
 
4.  SECURED SHORT TERM BORROWINGS:
 
     The Company has entered into an agreement with a consortium of three Indian
Government owned commercial banks to obtain working capital credit facilities.
The consortium was established in February 1995. While the three banks have
agreed to a total extension of credit and an allocation of participation, each
bank independently sanctions its portion of the participation. The lead bank in
the consortium, Indian Bank, has fully sanctioned its limit, while the other two
banks have only partially sanctioned their participation as of January 28, 1996.
 
     The credit agreement with the consortium has four separate facilities,
namely, export sales accounts receivable bill discounting ("bill discounting"),
exports sales order based inventory packing credit ("packing credit"), foreign
letters of credit ("letters of credit" or "LC"), and letters of guarantee
("guarantee").
 
     Bill discounting is a post-shipment credit facility used to finance export
receivables. Under the Company's bill discounting lines, export invoices are
presented to the bank, upon which the bank advances funds for the full value of
the invoice. Bills are typically discounted for ninety days. This facility is
self-

liquidating in nature whereby advances made by the bank to the Company against
bills discounted are settled through direct retirement of bills by the foreign
customers.
 
     Under the packing credit advance which is a pre-shipment facility, the bank
finances procurement of inventories and other costs incurred for fulfillment of
the Division's export orders. The advances under this facility are liquidated
using the proceeds of bills discounted by the Division. The Division has been
fully utilizing its sanctioned credit limits on its bill discounting and packing
credit facilities, and therefore the total credit availed by the Division
facilitates a continuous rotation of its inventory and invoice financing
requirements.
 
     Under the letter of credit facility, the bank guarantees timely payments to
the Division's foreign suppliers. Letter of credit is a non-funded limit which,
when issued, results in a contingent liability to the Division. The Division is
obligated to pay the bank at the time the bank remits money against documents
presented by the foreign supplier. Contingent liabilities arising from the use
of letters of credit have not been included in the Division's statements but
have been disclosed in Note 7 below.
 
     Letters of guarantee are provided by the bank on behalf of the Division to
third parties with which it has business dealings, to guarantee due performance
of contracts as well as fulfillment of monetary obligations by the Division.

     Bill discounting agreements are secured by export receivables. Packing
credit agreements are secured by a first charge on the Company's stocks of raw
materials, work in process and finished goods inventories.
 
     Outstanding letters of credit are secured by a charge on goods covered
under the letter of credit and a lien on deposits made by the Company with the
banks.
 
     Letters of guarantee are secured by counter guarantees issued by the
Company and a lien on deposits made by the Company with the banks.
 
     All the above agreements and facilities are fully covered by the personal
guarantee of the Chairman of the Company. The banks have sought for a second
collateral on the Company's plant and equipment, present and future, which have
already been used as collateral for the Company's secured long term loans (see
Note 5 below). As of the date of the statements, the Company was in the process
of fulfilling this requirement.

                        (CURRENCY: UNITED STATES DOLLAR)
 
                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
     According to the terms stipulated in the credit facility sanction letter of
Indian Bank, the Company's owners were required to contribute unsecured loans of
approximately $1.8 million and increase the paid-in capital of the Company to
$611,281 (from $69,463) before September 30, 1995. The Company has not fulfilled
this requirement as of the date of the statements. However, the Company has
obtained an undertaking from JTS, that advances made to the Division by JTS to
the extent of $2,558,650, will not be withdrawn or adjusted, either in part or
full, against the bills drawn by the Division, and, in due course, will be
converted into equity capital/unsecured loan.
 
5.  SECURED LONG TERM LOANS:
 
     The Company has entered into term loan agreements with the Industrial
Credit and Investment Corporation of India Limited ("ICICI"), a term lending
institution in India. In September 1992, the Company was sanctioned a rupee loan
of approximately $571,429 for the purpose of augmenting its existing
manufacturing facilities. Approximately $304,713 was available to the Company to
borrow as of January 31, 1995, subsequent to which the Company decided not to
fully avail of this loan before the last date of withdrawal, February 15, 1995.
The loan is repayable in Indian rupees in 12 equal quarterly installments of
approximately $19,450 each commencing from May 1995. Interest on outstanding
amounts are payable quarterly at the rate of 20% per annum.
 
     In October 1994, the Company was sanctioned an additional loan by the
ICICI, for approximately $2,550,000, denominated in four foreign currencies, for
the import of capital equipment. The Division had not borrowed against the loan
as of January 31, 1995, and had utilized the loan for a US dollar equivalent
amount of $2,625,758 as of January 28, 1996. As of January 28, 1996 there were
immaterial unutilized balances in three of the four foreign currencies under the
loan, which were cancelled by ICICI on February 22, 1996 based on a written
request by the Company. The loan is repayable in US dollar in 13 equal quarterly
installments of $201,981 each commencing from April 1997. Interest on
outstanding amounts is payable quarterly at the rate of US dollar LIBOR plus
2.75% per annum. For the period from February 1, 1995 to January 28, 1996, the
interest rates on this loan ranged from 8.7 to 9.5% per annum.
 
     Both loans are secured by all of the Company's property and equipment and
are fully covered by the personal guarantee of the Chairman of the Company.
According to the terms of the agreement for the foreign currency loan, the
Company's promoters were required to contribute unsecured loans of approximately
$1.8 million and increase the paid-in capital of the Company to $611,281 (from
$69,463). Though this amount has not been contributed by the owners as of the
date of the statements, the Company has obtained an undertaking from JTS, that
advances made to the Division by JTS to the extent of $2,558,650, will not be
withdrawn or adjusted, either in part or full, against the bills drawn by the
Division, and, in due course, will be converted into equity capital/unsecured
loan.
 
     In addition to the ICICI term loans, the Company has entered into a term
loan agreement with Corporation Bank, a Government owned commercial bank in
India, for the purchase of automobiles. As of January 28, 1996, the Division had
utilized approximately $31,386 of the total sanctioned amount of $41,678. The
loan is secured by the automobiles and is repayable in thirty equal monthly
installments of $1,047 each.

8.  RELATED PARTY TRANSACTIONS:
 
     As discussed in Note 1 above, the Division has functioned as a
manufacturing arm of JTS since its association with JTS. Apart from JTS, the
Division's related parties include Xyratex (former subcontractor of JTS), Nidec
Corporation (supplier to the Company and an equity investee in JTS), and
entities which are owned and/or controlled by the Chairman of the Company or his
relatives.
 
     JTS loaned manufacturing equipment with an historical cost of approximately
$4,400,000 and $530,000 located at the Division at January 28, 1996 and January
31, 1995.
 
     The Division's related party transactions during the period from February
1, 1995 to January 28, 1996 primarily consist of transactions with JTS and
Xyratex. These transactions include, inter alia, purchase of fixed assets and
raw materials from JTS, receipt of certain fixed assets on loan basis from JTS,
receipt of certain raw material free of cost from JTS, sale of disk drives to
JTS, advances received from JTS, remittances made to JTS, assumption of obsolete
inventories and warranty costs by JTS, sale of subassemblies and raw material to
Xyratex, and purchase of tools from Xyratex. Since the VCMA business was part of
the Company until January 28, 1996, transactions between the Division and the
VCMA business have not been considered as related party transactions.

     The Company has been capitalized since inception with 200,000 shares of
equity stock at a par value of Indian rupees 10 each and 5,000 shares of
preferred stock at a par value of Indian rupees 100 each. The Company's lone
preferred stock shareholder is the son of the Chairman of the Company. As part
of the transfer of the Company's VCMA business to a related party and the
proposed acquisition of the Division by JTS, it was decided in March 1995 to
retire the preferred stock of the Company. Effective January 28, 1996, all
preferred shares were retired for a consideration of Indian rupees 500,000
($13,893). As of January 28, 1996, this amount has been included in "Due to
related parties, net" (see Note 6 above).

9.  OTHER MATTERS:
 
     Technical Know-how and Collaboration Agreement
 
     Foreign currency transactions with parties outside India are subject to
controls imposed by the Reserve Bank of India ("RBI"), India's central bank.
Funds can only be remitted for payments against specific invoices for receipt of
materials or equipment and certain additional limited uses. Except for payments
below $5,000, cash in advance or deposit payments are not freely permitted to
parties outside the country. As part of the Company's disk drive EOU project
approval, the Government has allowed the Company to pay $2 million to JTS for
technical know-how fees. The Company is yet to finalize its agreement with JTS
for the payment of technical know-how fees as of the date of the statements. The
Division has not recorded any liability for possible future payment of technical
know-how fees due to the anticipated acquisition of the Company by JTS. The
Company's term loan agreements with ICICI contains certain restrictions on the
timing and period of payment of technical know-how fees.
 
     Divestiture of Voice Coil Business
 
     The Company transferred the VCMA business, after write-offs of
approximately $350,000 of related party balances, to Tancom Electronics
("Tancom") as of January 28, 1996. Such transfer included plant and equipment
and inventories of the VCMA business, along with certain other assets and
liabilities.
 
     Tancom is owned and controlled by the Chairman of the Company and his
family members and is therefore considered a related party. Retained earnings
attributable to the VCMA business since April 1, 1994 less advances made to
certain related parties were also transferred to Tancom. The Division expects to
continue to purchase voice coil assemblies from Tancom, provided their prices
remain competitive. The Division has not entered into any agreement mandating
the purchase of voice coil assemblies from Tancom.
 
     As of January 28, 1996, the total value of assets transferred to Tancom was
$558,146 and the total value of liabilities transferred totalled $28,148.
Retained earnings of the VCMA business transferred to Tancom totalled $418,493.
Accounts receivable of $428,080 and accounts payable of $236,163 relating to the
voice coil business, outstanding as of January 28, 1996 has been included in the
Statement of Assets and Liabilities of the Division due to regulatory
constraints on transfer of foreign currency receivables and payables. All of the
accounts receivables of the VCMA business are owing from Tantec Magnetics, a
related party to the Company.
 
10.  SUBSEQUENT EVENTS:
 
     New Long Term Loan
 
     On February 20, 1996, the Company was sanctioned an additional foreign
currency loan of $10 million, to be reduced to the extent of participation by
other institutions, by the ICICI for the proposed expansion of its disk drive
business. The Company had received a letter of intent ("letter") from the ICICI
the terms and conditions of which have to be agreed upon by the Company within
30 days before a formal foreign currency loan agreement ("loan agreement") could
be executed by both parties. Interest on this proposed loan shall be payable at
the lending rates of the ICICI prevailing on the date of execution of the loan
agreement. Lending rates of the ICICI are US dollar LIBOR, plus a fixed percent,
if the funds are provided out of the floating rate US dollar funds, and a fixed
rate per annum, if the funds are provided out of fixed rate US dollar funds.
According to the letter, this loan will be secured by a first charge on all of
the Company's equipment, both present and future, subject to any prior charge on
specified equipment in favor of the Company's banks. The Company is also
required to provide an irrevocable and unconditional guarantee from the Chairman
in favor of ICICI for due repayment of the loan along with all interest and any
other moneys. Further, for the loan to

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)
 
become effective, the Company would have to raise $5,584,885 by issue of equity
shares to promoters, obtain an unsecured loan of $3,601,000 and state subsidies
of $236,177 to meet a part of the cost of the project.
 
     On March 18, 1996, the Company entered into a loan agreement with the ICICI
for $7 million towards their participation in the total sanctioned amount of $10
million. The loan is repayable in US dollar in 12 equal quarterly installments
of $583,333 each commencing form May 20, 1998. The Company has procured an
irrevocable and unconditional guarantee from the Chairman of the Company as
required by the letter of intent. The funding of this loan by ICICI is dependent
upon the Company's compliance with the pre-disbursement conditions relating to
raising of additional equity capital and obtaining of unsecured loans and state
subsidies, mentioned above. If the Company does not comply with these
pre-disbursement conditions, the previously obtained loans from ICICI (see Note
5) could be held in default and ICICI may have the right to recall the earlier
loans, besides not funding the current loan.

issued, but in lieu thereof each holder of shares of Atari Common Stock who
would otherwise be entitled to a fraction of a share of JTS Common Stock (after
aggregating all fractional shares of JTS Common Stock to be received by such
holder) shall receive from JTS an amount of cash (rounded to the nearest whole
cent) equal to the product of (i) such fraction, multiplied by (ii) the closing
price of a share of Atari Common Stock on the trading day immediately prior to
the Effective Time, as reported by the American Stock Exchange.
 
     1.7 Surrender of Certificates.
 
     (a) Exchange Agent.  Registrar and Transfer Company, Cranford, NJ, shall
act as exchange agent (the "Exchange Agent") in the Merger.
 
     (b) JTS to Provide Common Stock and Cash.  Promptly after the Effective
Time, JTS shall make available to the Exchange Agent for exchange in accordance
with this Article I, through such procedures as JTS may reasonably adopt, (i)
the shares of JTS Common Stock issuable pursuant to Section 1.6(a) in exchange
for shares of Atari Common Stock outstanding immediately prior to the Effective
Time and (ii) cash in an amount sufficient to permit payment of cash in lieu of
fractional shares pursuant to Section 1.6(g).
 
     (c) Exchange Procedures.  Promptly after the Effective Time, the Surviving
Corporation shall cause to be mailed to each holder of record of a certificate
or certificates (the "Certificates") which immediately prior to the Effective
Time represented outstanding shares of Atari Common Stock, whose shares were
converted into the right to receive shares of JTS Common Stock (and cash in lieu
of fractional shares) pursuant to Section 1.6, (i) a letter of transmittal
(which shall specify that delivery shall be effected, and risk of loss and title
to the Certificates shall pass, only upon receipt of the Certificates by the
Exchange Agent, and shall be in such form and have such other provisions as JTS
may reasonably specify) and (ii) instructions for use in effecting the surrender
of the Certificates in exchange for certificates representing shares of JTS
Common Stock (and cash in lieu of fractional shares). Upon surrender of a
Certificate for cancellation to the Exchange Agent or to such other agent or
agents as may be appointed by JTS, together with such letter of transmittal,
duly completed and validly executed in accordance with the instructions thereto,
the holder of such Certificate shall be entitled to receive in exchange therefor
a certificate representing the number of whole shares of JTS Common Stock and
payment in lieu of fractional shares which such holder has the right to receive
pursuant to Section 1.6, and the Certificate so surrendered shall forthwith be
canceled. Until so surrendered, each outstanding Certificate that, prior to the
Effective Time, represented shares of Atari Common Stock will be deemed from and
after the Effective Time, for all corporate purposes, other than the payment of
dividends, to evidence the ownership of the number of full shares of JTS Common
Stock into which such shares of Atari Common Stock shall have been so converted
and the right to receive an amount in cash in lieu of the issuance of any
fractional shares in accordance with Section 1.6.
 
     (d) Distributions With Respect to Unexchanged Shares.  No dividends or
other distributions with respect to JTS Common Stock with a record date after
the Effective Time will be paid to the holder of any unsurrendered Certificate
with respect to the shares of JTS Common Stock represented thereby until the
holder of record of such Certificate shall surrender such Certificate. Subject
to applicable law, following surrender of any such Certificate, there shall be
paid to the record holder of the certificates representing whole shares of JTS
Common Stock issued in exchange therefor, without interest, at the time of such
surrender, the amount of any such dividends or other distributions with a record
date after the Effective Time theretofore payable (but for the provisions of
this Section 1.7(d)) with respect to such shares of JTS Common Stock.
 
     (e) Transfers of Ownership.  If any certificate for shares of JTS Common
Stock is to be issued in a name other than that in which the Certificate
surrendered in exchange therefor is registered, it will be a condition of the
issuance thereof that the Certificate so surrendered will be properly endorsed
and otherwise in proper form for transfer and that the person requesting such
exchange will have paid to JTS or any agent designated by it any transfer or
other taxes required by reason of the issuance of a certificate for shares of
JTS
 
                                        3

Common Stock in any name other than that of the registered holder of the
Certificate surrendered, or established to the satisfaction of JTS or any agent
designated by it that such tax has been paid or is not payable.
 
     (f) No Liability.  Notwithstanding anything to the contrary in this Section
1.7, none of the Exchange Agent, the Surviving Corporation or any party hereto
shall be liable to any person for any amount properly paid to a public official
pursuant to any applicable abandoned property, escheat or similar law.
 
     1.8 No Further Ownership Rights in Atari Stock.  All shares of JTS Common
Stock issued upon the surrender for exchange of shares of Atari Common Stock in
accordance with the terms hereof (including any cash paid in lieu of fractional
shares) shall be deemed to have been issued in full satisfaction of all rights
pertaining to such shares of Atari Common Stock, and there shall be no further
registration of transfers on the records of the Surviving Corporation of shares
of Atari Common Stock which were outstanding immediately prior to the Effective
Time. If, after the Effective Time, Certificates are presented to the Surviving
Corporation for any reason, they shall be canceled and exchanged as provided in
this Article I.
 
     1.9 Lost, Stolen or Destroyed Certificates.  In the event any Certificates
shall have been lost, stolen or destroyed, the Exchange Agent shall issue in
exchange for such lost, stolen or destroyed Certificates, upon the making of an
affidavit of that fact by the holder thereof, such shares of JTS Common Stock
(and cash in lieu of fractional shares) as may be required pursuant to Section
1.6; provided, however, that JTS may, in its discretion and as a condition
precedent to the issuance thereof, require the owner of such lost, stolen or
destroyed Certificates to deliver a bond in such sum as it may reasonably direct
as indemnity against any claim that may be made against JTS, the Surviving
Corporation or the Exchange Agent with respect to the Certificates alleged to
have been lost, stolen or destroyed.
 
     1.10 Tax Consequences.  It is intended by the parties hereto that the
Merger shall constitute a reorganization within the meaning of Section 368 of
the Code.
 
     1.11 Taking of Necessary Action; Further Action.  If, at any time after the
Effective Time, any further action is necessary or desirable to carry out the
purposes of this Agreement and to vest the Surviving Corporation with full
right, title and possession to all assets, property, rights, privileges, powers
and franchises of Atari, the officers and directors of Atari are fully
authorized in the name of the corporation or otherwise to take, and will take,
all such lawful and necessary action, so long as such action is not inconsistent
with this Agreement.
 
     1.12 Dissenting JTS Shares.
 
     (a) Notwithstanding any provision of this Agreement to the contrary, any
shares of JTS Common Stock or JTS Series A Preferred Stock held by a holder who
has exercised dissenters' rights for such shares in accordance with Delaware Law
or California General Corporation Law to the extent such law is applicable by
virtue of Section 2115 thereof ("California Law") and who, as of the Effective
Time, has not effectively withdrawn or lost such dissenters' rights ("Dissenting
Shares"), shall be entitled to such rights as are granted by Delaware Law or
California Law.
 
     (b) JTS shall give Atari (i) prompt notice of any written demands received
by JTS for an appraisal of shares of capital stock of JTS pursuant to Section
262 of Delaware Law or Chapter 13 of California Law, withdrawals of such
demands, and any other related instruments served pursuant to Delaware Law or
California Law and received by JTS and (ii) the opportunity to participate in
all negotiations and proceedings with respect to such demands. JTS shall not,
except with the prior written consent of Atari, voluntarily make any payment
with respect to any such demands or offer to settle or settle any such demands.

     Except as disclosed in a document of even date herewith and delivered by
JTS to Atari prior to the execution and delivery of this Agreement and referring
to the representations and warranties in this Agreement (the "JTS Disclosure
Schedule"), JTS represents and warrants to Atari as follows:
 
     2.1 Organization, Standing and Power.  Each of JTS and its subsidiaries is
a corporation duly organized, validly existing and in good standing under the
laws of its jurisdiction of organization. Each of JTS and its subsidiaries has
the corporate power to own its properties and to carry on its business as now
being conducted and as proposed to be conducted and is duly qualified to do
business and is in good standing in each jurisdiction in which the failure to be
so qualified and in good standing would have a Material Adverse Effect on JTS
and its subsidiaries, taken as a whole. JTS has delivered a true and correct
copy of the Certificate of Incorporation and Bylaws or other charter documents,
as applicable, of JTS and each of its subsidiaries, each as amended to date, to
Atari. Neither JTS nor any of its subsidiaries is in violation of any of the
provisions of its Certificate of Incorporation or Bylaws or equivalent
organizational documents. JTS is the owner of all outstanding shares of capital
stock of each of its subsidiaries and all such shares are duly authorized,
validly issued, fully paid and nonassessable. All of the outstanding shares of
capital stock of each such subsidiary are owned by JTS free and clear of all
liens, charges, claims or encumbrances or rights of others. There are no
outstanding subscriptions, options, warrants, puts, calls, rights, exchangeable
or convertible securities or other commitments or agreements of any character
relating to the issued or unissued capital stock or other securities of any such
subsidiary, or otherwise obligating JTS or any such subsidiary to issue,
transfer, sell, purchase, redeem or otherwise acquire any such securities.
Except as disclosed in the JTS Disclosure Schedule, JTS does not directly or
indirectly own any equity or similar interest in, or any interest convertible or
exchangeable or exercisable for, any equity or similar interest in, any
corporation, partnership, joint venture or other business association or entity.
 
     2.2 Capital Structure.  The authorized capital stock of JTS consists of
90,000,000 shares of Common Stock, $.000001 par value, and 70,000,000 shares of
Preferred Stock, $.000001 par value, all of which is designated Series A
Preferred Stock, of which there were issued and outstanding as of the close of
business on April 5, 1996, 9,204,741 shares of Common Stock and 29,696,370
shares of Series A Preferred. The JTS Disclosure Schedule contains a true and
complete list of the holders of JTS Common Stock and JTS Series A Preferred
Stock and the number of shares held by each such holder on April 5, 1996. There
are no other outstanding shares of capital stock or voting securities. Each
outstanding share of JTS Series A Preferred Stock is convertible into one (1)
share of JTS Common Stock. All outstanding shares of JTS Common Stock and JTS
Series A Preferred Stock are duly authorized, validly issued, fully paid and
non-assessable and are free of any liens or encumbrances other than any liens or
encumbrances created by or imposed upon the holders thereof, and are not subject
to preemptive rights or rights of first refusal created by statute, the
Certificate of Incorporation or Bylaws of JTS or any agreement to which JTS is a
party or by which it is bound. As of the close of business on April 5, 1996, JTS
has reserved (i) 4,300,000 shares of JTS Common Stock for issuance to employees
and consultants pursuant to the JTS 1995 Stock Option Plan (the "JTS Stock

A Preferred Stock and JTS Common Stock for issuance upon conversion of the note
issued to Atari on February 13, 1996 and upon exercise of the warrants issuable
to Atari pursuant to such note. Since April 5, 1996, JTS has not issued or
granted additional options under the JTS Stock Option Plan. Other than pursuant
to this Agreement, there are no other options, warrants, calls, rights,
commitments or agreements of any character to which JTS is a party or by which
it is bound obligating JTS to issue, deliver, sell, repurchase or redeem, or
cause to be

JTS or obligating JTS to grant, extend, accelerate the vesting of, change the
price of, or otherwise amend or enter into any such option, warrant, call,
right, commitment or agreement. The terms of the JTS Stock Option Plan and the
JTS Warrants permit the assumption or substitution of options or warrants, as
applicable, to purchase Atari Common Stock as provided in this Agreement,
without the consent or approval of the holders of such securities, the JTS
stockholders, or otherwise. True and complete copies of all agreements and
instruments relating to or issued under the JTS Stock Option Plan or JTS
Warrants have been made available to Atari and such agreements and instruments
have not been amended, modified or supplemented, and there are no agreements to
amend, modify or supplement such agreements or instruments in any case from the

     2.3 Authority.  JTS has all requisite corporate power and authority to
enter into this Agreement and to consummate the transactions contemplated
hereby. The execution and delivery of this Agreement and the consummation of the
transactions contemplated hereby have been duly authorized by all necessary
corporate action on the part of JTS, subject only to the approval of the Merger
by JTS's stockholders as contemplated by Section 6.1(a). This Agreement has been
duly executed and delivered by JTS and constitutes the valid and binding
obligation of JTS. The execution and delivery of this Agreement by JTS does not,

lapse of time, or both), or give rise to a right of termination, cancellation or
acceleration of any obligation or loss of any benefit under (i) any provision of
the Certificate of Incorporation or Bylaws of JTS or any of its subsidiaries, as
amended, or (ii) any material mortgage, indenture, lease, contract or other
agreement or instrument, permit, concession, franchise, license, judgment,
order, decree, statute, law, ordinance, rule or regulation applicable to JTS or
any of its subsidiaries or any of their properties or assets. No consent,
approval, order or authorization of, or registration, declaration or filing
with, any court, administrative agency or commission or other governmental
authority or instrumentality ("Governmental Entity") is required by or with
respect to JTS or any of its subsidiaries in connection with the execution and
delivery of this Agreement or the consummation of the transactions contemplated
hereby, except for (i) the filing of the Certificate of Merger as provided in

registrations, declarations and filings as may be required under applicable
state securities laws and the securities laws of any foreign country; (iii) such

filings, approvals and registrations which, if not obtained or made, would not
have a Material Adverse Effect on JTS and its subsidiaries, taken as a whole,
and would not prevent, alter or materially delay any of the transactions
contemplated by this Agreement. The JTS Disclosure Schedule sets forth a full
and complete list of all necessary consents, waivers and approvals of third
parties applicable to the operations of JTS that are required to be obtained by
JTS in connection with the execution and delivery of this Agreement or the
Merger Agreement by JTS or the consummation by JTS of the transactions
contemplated hereby or thereby, except any such consents, waivers and approvals,
which, if not obtained, would not have a Material Adverse Effect on JTS and its
subsidiaries, taken as a whole. Prior to the Closing Date, JTS will obtain all
such consents.
 
     The Stock Purchase Agreement dated as of April 4, 1996 between JTS and
Lunenburg, S.A., a Panama corporation, together with all documents executed in
connection therewith (the "Moduler Agreement"), has been duly executed and
delivered by JTS, the transactions contemplated thereby have been consummated,
and the Moduler Agreement constitutes a valid and binding obligation of JTS. JTS
has provided to Atari a true, correct and complete copy of the Moduler
Agreement, and has performed all obligations required to be performed by it to
date under the Moduler Agreement. To JTS' best knowledge, (a) the other parties
to the Moduler Agreement have performed all obligations required to be performed
by them to date under such agreement, (b) as to such other parties, the Moduler
Agreement is valid, binding and enforceable in accordance with its terms and (c)

                                  ARTICLE III
 
                    REPRESENTATIONS AND WARRANTIES OF ATARI
 
     Except as disclosed in the Atari SEC Documents (as defined in Section 3.4)
or in a document of even date herewith and delivered by Atari to JTS prior to
the execution and delivery of this Agreement and referring to the
representations and warranties in this Agreement (the "Atari Disclosure
Schedule"), Atari represents and warrants to JTS as follows:
 
     3.1 Organization, Standing and Power.  The Atari Disclosure Schedule
identifies each subsidiary of Atari that is a "significant subsidiary" of Atari
as defined by Rule 1-02(v) of Regulation S-X (the "Significant Subsidiaries").
Atari and each of its Significant Subsidiaries is a corporation duly organized,
validly existing and in good standing under the laws of its jurisdiction of
organization. Each of Atari and its Significant Subsidiaries has the corporate
power to own its properties and to carry on its business as now being conducted
and as proposed to be conducted and is duly qualified to do business and is in
good standing in each jurisdiction in which the failure to be so qualified and
in good standing would have a Material Adverse Effect on Atari and its
subsidiaries, taken as a whole. Atari has delivered a true and correct copy of
the Articles of Incorporation and Bylaws or other charter documents, as
applicable, of Atari and each of its Significant Subsidiaries, each as amended
to date, to JTS. Neither Atari nor any of its Significant Subsidiaries is in
violation of any of the provisions of its Articles of Incorporation or Bylaws or
equivalent organizational documents. Atari is the owner of all outstanding
shares of capital stock of each of its subsidiaries and all such shares are duly
authorized, validly issued, fully paid and nonassessable. All of the outstanding
shares of capital stock of each such subsidiary are owned by Atari free and
clear of all liens, charges, claims or encumbrances or rights of others. There
are no outstanding subscriptions, options, warrants, puts, calls, rights,
exchangeable or convertible securities or other commitments or agreements of any
character relating to the issued or unissued capital stock or other securities
of any such subsidiary, or otherwise obligating Atari or any such subsidiary to
issue, transfer, sell, purchase, redeem or otherwise acquire any such
securities. Except as disclosed in the Atari SEC Documents (as defined in
Section 3.4), Atari does not directly or indirectly own any equity or similar
interest in, or any interest convertible or exchangeable or exercisable for, any
equity or similar interest in, any corporation, partnership, joint venture or
other business association or entity.
 
     3.2 Capital Structure.  The authorized capital stock of Atari consists of
100,000,000 shares of Common Stock, $.01 par value, and 10,000,000 shares of
Preferred Stock, $.01 par value, of which there were issued and outstanding as
of the close of business on March 29, 1996, 63,727,318 shares of Common Stock
and no shares of Preferred Stock. There are no other outstanding shares of
capital stock or voting securities of Atari, other than shares of Atari Common
Stock issued after March 29, 1996 upon the exercise of options issued under the
Atari 1986 Stock Option Plan (the "Atari Stock Option Plan"). All outstanding
shares of Atari have been duly authorized, validly issued, fully paid and are
nonassessable and free of any liens or encumbrances other than any liens or
encumbrances created by or imposed upon the holders thereof, and are not subject
to
 
                                       12
<PAGE>   197
 
preemptive rights or rights of first refusal created by statute, the Articles of
Incorporation or Bylaws of Atari or any agreement to which Atari is a party or
by which it is bound. As of the close of business on March 29, 1996, Atari has
reserved 3,000,000 shares of Common Stock for issuance to employees, directors
and consultants pursuant to the Atari Stock Option Plan, of which 599,674 shares
have been issued pursuant to option exercises, and 899,125 shares are subject to
outstanding, unexercised options. Since March 29, 1996, Atari has not issued or
granted additional options under the Atari Stock Option Plan. There are no other
options, warrants, calls, rights, commitments or agreements of any character to
which Atari is a party or by which it is bound obligating Atari to issue,
deliver, sell, repurchase or redeem, or cause to be issued, delivered, sold,
repurchased or redeemed, any shares of the capital stock of Atari or obligating
Atari to grant, extend or enter into any such option, warrant, call, right,
commitment or agreement.
 
     3.3 Authority.  Atari has all requisite corporate power and authority to
enter into this Agreement and to consummate the transactions contemplated
hereby. The execution and delivery of this Agreement and the consummation of the
transactions contemplated hereby have been duly authorized by all necessary
corporate action on the part of Atari, subject only to the approval of the
Merger by the Atari stockholders as contemplated by Section 6.1(a). This
Agreement has been duly executed and delivered by Atari and constitutes the
valid and binding obligations of Atari. The execution and delivery of this
Agreement do not, and the consummation of the transactions contemplated hereby
will not, conflict with, or result in any violation of, or default under (with
or without notice or lapse of time, or both), or give rise to a right of
termination, cancellation or acceleration of any obligation or loss of any
benefit under (i) any provision of the Articles of Incorporation or Bylaws of
Atari or any of its Significant Subsidiaries, as amended, or (ii) any material
mortgage, indenture, lease, contract or other agreement or instrument, permit,
concession, franchise, license, judgment, order, decree, statute, law,
ordinance, rule or regulation applicable to Atari or any of its Significant
Subsidiaries or any of their properties or assets. No consent, approval, order
or authorization of, or registration, declaration or filing with, any
Governmental Entity, is required by or with respect to Atari or any of its
Significant Subsidiaries in connection with the execution and delivery of this
Agreement by Atari or the consummation by Atari of the transactions contemplated
hereby, except for (i) the filing of the Certificate of Merger as provided in
Section 1.2, (ii) the filing with the SEC and the American Stock Exchange of the
Proxy Statement relating to the Atari Stockholders Meeting, (iii) the filing of
a Form 8-K and Form 10-C with the SEC and the American Stock Exchange within 15
days and 10 days, respectively, after the Closing Date, (iv) any filings as may
be required under applicable state securities laws and the securities laws of
any foreign country, (v) such filings as may be required under HSR, (vi) such
filings as may be required under the rules and regulations of the American Stock
Exchange, and (vii) such other consents, authorizations, filings, approvals and
registrations which, if not obtained or made, would not have a Material Adverse
Effect on Atari and its subsidiaries, taken as a whole, and would not prevent,
alter or materially delay any of the transactions contemplated by this
Agreement. The Atari Disclosure Schedule sets forth a full and complete list of
all necessary consents, waivers and approvals of third parties applicable to the
operations of Atari that are required to be obtained by Atari in connection with
the execution and delivery of this Agreement or the Merger Agreement by Atari or
the consummation by Atari of the transactions contemplated hereby or thereby,
except any such consents, waivers and approvals, which, if not obtained, would
not have a Material Adverse Effect on Atari and its subsidiaries, taken as a
whole. Prior to the Closing Date, Atari will obtain all such consents.
 
     3.4 SEC Documents; Financial Statements.  Atari has furnished to JTS a true
and complete copy of each report, registration statement, definitive proxy
statement, and other filings filed with the SEC by Atari since January 1, 1993
(other than filings pursuant to Section 16 of the Securities Exchange Act of
1934, as amended (the "Exchange Act"), and any registration statement on Form
S-8), and prior to the Effective Time, Atari will have furnished JTS with true
and complete copies of any additional documents (other than filings pursuant to
Section 16 of the Exchange Act, and any registration statement on Form S-8)
filed with the SEC by Atari prior to the Effective Time (collectively, the
"Atari SEC Documents"). As of their respective filing dates, the Atari SEC
Documents complied in all material respects with the requirements of the
Exchange Act and the Securities Act, and none of the Atari SEC Documents
contained any untrue statement of a material fact or omitted to state a material
fact required to be stated therein or necessary to make the statements made
therein, in light of the circumstances in which they were made, not misleading,
except to the
 
                                       13
<PAGE>   198
 
extent corrected by a subsequently filed Atari SEC Document. The financial
statements of Atari, including the notes thereto, included in the Atari SEC
Documents (the "Atari Financial Statements") were complete and correct in all
material respects as of their respective dates, complied as to form in all
material respects with applicable accounting requirements and with the published
rules and regulations of the SEC with respect thereto as of their respective
dates, and have been prepared in accordance with generally accepted accounting
principles applied on a basis consistent throughout the periods indicated and
consistent with each other (except as may be indicated in the notes thereto or,
in the case of unaudited statements included in Quarterly Reports on Form 10-Qs,
as permitted by Form 10-Q of the SEC). The Atari Financial Statements are in
accordance with the books and records of Atari and fairly present the
consolidated financial condition and operating results of Atari and its
subsidiaries at the dates and during the periods indicated therein (subject, in
the case of unaudited statements, to normal, recurring year-end adjustments).
There has been no change in Atari accounting policies except as described in the
notes to the Atari Financial Statements.
 
     3.5 Absence of Certain Changes.  Since December 31, 1995 (the "Atari
Balance Sheet Date"), Atari has conducted its business in the ordinary course
consistent with past practice and there has not occurred: (i) any change, event
or condition (whether or not covered by insurance) that has resulted in, or
might reasonably be expected to result in, a Material Adverse Effect to Atari
and its subsidiaries, taken as a whole; (ii) any acquisition, sale or transfer
of any material asset of Atari or any of its subsidiaries other than in the
ordinary course of business and consistent with past practice; (iii) any change
in accounting methods or practices (including any change in depreciation or
amortization policies or rates) by Atari or any revaluation by Atari of any of
its assets; (iv) any issuance or agreement to issue or any commitment to issue
any equity security, bond, note or other security of Atari or any of its
subsidiaries; (v) any declaration, setting aside, or payment of a dividend or
other distribution with respect to the shares of Atari, or any direct or
indirect redemption, purchase or other acquisition by Atari of any of its shares
of capital stock; (vi) any material contract entered into by Atari, other than
in the ordinary course of business and as provided to JTS, or any amendment or
termination of, or default under, any material contract to which Atari is a
party or by which it is bound; or (vii) any negotiation or agreement by Atari or
any of its subsidiaries to do any of the things described in the preceding
clauses (i) through (vii) (other than negotiations with JTS regarding the
transactions contemplated by this Agreement).
 
     3.6 Absence of Undisclosed Liabilities.  Atari has no material obligations
or liabilities of any nature (matured or unmatured, fixed or contingent) other
than (i) those set forth or adequately provided for in the Balance Sheet
included in Atari's Annual Report on Form 10-K for the period ended December 31,
1995 (the "Atari Balance Sheet"), (ii) those incurred in the ordinary course of
business and not required to be set forth in the Atari Balance Sheet under
generally accepted accounting principles, and (iii) those incurred in the
ordinary course of business since the Atari Balance Sheet Date and consistent
with past practice.
 
     3.7 Litigation.  There is no private or governmental action, suit,
proceeding, claim, arbitration or investigation pending before any agency, court
or tribunal, foreign or domestic, or, to the knowledge of Atari or any of its
subsidiaries, threatened against Atari or any of its subsidiaries or any of
their respective properties or any of their respective officers or directors (in
their capacities as such) that, individually or in the aggregate, could have a
Material Adverse Effect on Atari and its subsidiaries, taken as a whole. There
is no judgment, decree or order against Atari or any of its subsidiaries or, to
the knowledge of Atari or any of its subsidiaries, any of their respective
directors or officers (in their capacities as such) that could prevent, enjoin,
alter or delay any of the transactions contemplated by this Agreement, or that
could have a Material Adverse Effect on Atari and its subsidiaries, taken as a
whole. The outcome of the matter In re The Federated Group, Inc. Alleged Debtor
U.S.B.C. (N.D.Cal. Div. 5) No. 92-50412-JRG Chapter 7, is not reasonably likely
to have a Material Adverse Effect on Atari and its subsidiaries, taken as a
whole.
 
     3.8 Restrictions on Business Activities.  There is no agreement, judgment,
injunction, order or decree binding upon Atari or any of its subsidiaries which
has or could have the effect of prohibiting or materially impairing any current
or future business practice of Atari or any of its subsidiaries, any acquisition
of property by Atari or any of its subsidiaries or the conduct of business by
Atari or any of its subsidiaries as currently conducted or as proposed to be
conducted by Atari or any of its subsidiaries.
 
                                       14
<PAGE>   199
 
     3.9 Governmental Authorization.  Atari and each of its subsidiaries have
obtained each federal, state, county, local or foreign governmental consent,
license, permit, grant, or other authorization of a Governmental Entity (i)
pursuant to which Atari or any of its subsidiaries currently operates or holds
any interest in any of its properties or (ii) which is required for the
operation of Atari's or any of its subsidiaries' business or the holding of any
such interest (herein collectively called "Atari Authorizations"), and all of
such Atari Authorizations are in full force and effect, except where the failure
to obtain or have any of such Atari Authorizations could not reasonably be
expected to have a Material Adverse Effect on Atari and its subsidiaries, taken
as a whole.
 
     3.10 Title to Property.  Atari and its Significant Subsidiaries have good
and marketable title to all of their respective properties, interests in
properties and assets, real and personal, reflected in the Atari Balance Sheet
or acquired after the Atari Balance Sheet Date (except properties, interests in
properties and assets sold or otherwise disposed of since the Atari Balance
Sheet Date thereof in the ordinary course of business), free and clear of all
mortgages, liens, pledges, charges or encumbrances of any kind or character,
except (i) the lien of current taxes not yet due and payable, (ii) such
imperfections of title, liens and easements as do not and will not materially
detract from or interfere with the use of the properties subject thereto or
affected thereby, or otherwise materially impair business operations involving
such properties and (iii) liens securing debt which is reflected on the Atari
Balance Sheet. The plants, property and equipment of Atari and its Significant
Subsidiaries that are used in the operations of their businesses are in good
operating condition and repair. All properties used in the operations of Atari
and its Significant Subsidiaries are reflected in the Atari Balance Sheet to the
extent generally accepted accounting principles require the same to be
reflected. The Atari Disclosure Schedule identifies each parcel of real property
owned or leased by Atari or any of its Significant Subsidiaries
 
     3.11 Intellectual Property.  Atari and its Significant Subsidiaries own, or
are licensed or otherwise possess legally enforceable rights to use all
Intellectual Property that are used or proposed to be used in the business of
Atari and its Significant Subsidiaries as currently conducted or as proposed to
be conducted by Atari and its subsidiaries, except to the extent that the
failure to have such rights have not had and could not reasonably be expected to
have a Material Adverse Effect on Atari and its subsidiaries, taken as a whole.
To the knowledge of Atari and its Significant Subsidiaries, there is no material
unauthorized use, disclosure, infringement or misappropriation of any
Intellectual Property rights of Atari or any of its subsidiaries, any trade
secret material to Atari or any of its subsidiaries, or any Intellectual
Property right of any third party to the extent licensed by or through Atari or
any of its subsidiaries, by any third party, including any employee or former
employee of Atari or any of its subsidiaries. Neither Atari nor any of its
subsidiaries has entered into any agreement to indemnify any other person
against any charge of infringement of any Intellectual Property, other than
indemnification provisions (i) listed on the Atari Disclosure Schedule or (ii)
contained in purchase orders arising in the ordinary course of business.
 
     3.12 Environmental Matters.
 
     (a) To the knowledge of Atari and its Significant Subsidiaries, no
Hazardous Material is present in, on or under any property that Atari or any of
its subsidiaries has at any time owned, operated, occupied or leased (herein an
"Atari Facility"), except to the extent that such presence has not had and could
not reasonably be expected to have a Material Adverse Effect on Atari and its
subsidiaries, taken as a whole.
 
     (b) To the knowledge of Atari and its Significant Subsidiaries, neither
Atari nor any of its subsidiaries has engaged in a Hazardous Materials Activity
in material violation of any applicable foreign, federal, state or local
statute, rule, regulation, order or law.
 
     (c) To the knowledge of Atari and its Significant Subsidiaries, each of
Atari and its subsidiaries is and at all times has been in compliance with all
foreign, federal, state and local laws relating to emissions, discharges,
releases or threatened releases of Hazardous Materials, except to the extent
noncompliance with such laws has not had and could not reasonably be expected to
have a Material Adverse Effect on Atari and its subsidiaries, taken as a whole.
 
     (d) No action, proceeding, permit revocation, writ, injunction or claim is

recommendation or solicitation in support of any possible Atari Acquisition
Proposal by any person other than JTS. If Atari receives any unsolicited offer
or proposal to enter negotiations relating to an Atari Acquisition Proposal,
Atari shall immediately notify JTS thereof, including information as to the
identity of the party making any such offer or proposal and the specific terms
of such offer or proposal, as the case may be. Atari recognizes and acknowledges
that a breach of this Section 4.5 may cause irreparable and material loss and
damage to JTS as to which JTS may not have an adequate remedy at law or in
damages and that, accordingly, JTS agrees that the issuance of an injunction or
other equitable remedy is the appropriate remedy for any such breach.
Notwithstanding the foregoing, nothing contained in this Agreement (i) shall
prevent the Board of Directors of Atari from referring any third party to this
Section 4.5 or providing a copy of this Agreement (other than the JTS Disclosure
Schedule) to any third party, (ii) shall prevent the Board of Directors of Atari
from considering, negotiating, approving and recommending to the shareholders of
Atari an unsolicited bona fide written Atari Acquisition Proposal which the
Board of Directors of Atari determines in good faith (after consultation with
its financial advisors and after consultation with outside counsel as to whether
the Board of Directors is required to do so in order to discharge properly its
fiduciary duties to shareholders under applicable law) would result in a
transaction more favorable to the Company's shareholders from a financial point
of view than the transaction contemplated by this Agreement (any such Atari
Acquisition Proposal being referred to herein as a "Superior Atari Proposal").

     of Atari or any of its subsidiaries, or compel Atari or any of Atari's
     subsidiaries or JTS or any of JTS's subsidiaries to dispose of or hold

     of JTS or any of its subsidiaries, or compel Atari or any of Atari's
     subsidiaries or JTS or any of JTS's subsidiaries to dispose of or hold

as provided in Section 7.1, this Agreement shall forthwith become void and there
shall be no liability or obligation on the part of Atari and JTS or their

representations, warranties or covenants set forth this Agreement; provided
that, the provisions of Section 7.3 (Expenses) and this Section 7.2 shall remain
in full force and effect and survive any termination of this Agreement.

Stockholder set forth therein.
 
     4. REPRESENTATIONS, WARRANTIES AND COVENANTS OF STOCKHOLDER.  Stockholder
hereby represents, warrants and covenants to JTS that Stockholder (i) is the

herewith shall terminate and shall have no further force or effect as of the
Expiration Date.
 
     8. MISCELLANEOUS.

Agreement is held by a court of competent jurisdiction to be invalid, void or

Board of Directors
Atari Corporation
1196 Borregas Avenue
Sunnyvale, California 94089
 
Gentlemen:
 
     We understand that Atari Corporation, a Nevada corporation (the "Company"),
JT Storage, Inc., a Delaware corporation ("JTS"), and JTS Acquisition
Corporation, a Delaware corporation ("Newco"), propose to enter into an
Agreement and Plan of Reorganization, dated as of February 12, 1996 (the
"Reorganization Agreement"), pursuant to which the Company and JTS will be
merged with and into Newco, which will be the surviving entity (the "Merger").
Pursuant to the Merger, as more fully described in the February 2, 1996 draft of
the Reorganization Agreement provided to us by the Company, we understand that
each outstanding share of (a) the common stock of the Company, $.01 par value
per share (the "Company Common Stock"), (b) the common stock of JTS, par value
$.000001 per share, and (c) the Series A preferred stock of JTS, par value
$.000001 per share, in each case not owned directly or indirectly by Newco, will
be converted into 1.00 shares (the "Exchange Ratio") of the common stock, par
value $.01 per share, of Newco ("Newco Common Stock"). We understand that,
immediately following the Merger, the former securityholders of the Company and
JTS will own approximately 61% and 39% respectively, of the Newco Common Stock
on a fully diluted basis. We also understand that Newco is a newly formed
corporation with no material assets and no liabilities.
 
     You have asked for our opinion as investment bankers as to whether the
Exchange Ratio to be paid by Newco pursuant to the Merger is fair to the Company
from a financial point of view, as of the date hereof.
 
     In connection with our opinion, we have, among other things: (i) reviewed
certain publicly available financial and other data with respect to the Company,
including the consolidated financial statements for recent years and interim
periods to September 30, 1995, and certain other relevant financial and
operating data relating to the Company and JTS made available to us from
published sources and from the internal records of the Company and JTS,
including the consolidated financial statements of JTS for recent years and
interim periods to November 30, 1995; (ii) reviewed the February 2, 1996 draft
of the Reorganization Agreement provided to us by the Company; (iii) reviewed
certain historical market prices and trading volumes of the Company Common Stock
as reported in the American Stock Exchange; (iv) compared the Company and JTS
from a financial point of view with certain other companies in the computer
peripherals industry that we deemed to be relevant; (v) considered the financial
terms, to the extent publicly available, of selected recent business
combinations of companies in the computer peripherals industry that we deemed to
be comparable, in whole or in part, to the Merger; (vi) reviewed and discussed
with representatives of the management of the Company and JTS certain
information of a business and financial nature regarding the Company and JTS,
furnished to us by them; (vii) reviewed and discussed with representatives of
the management of the Company and JTS financial forecasts and related
assumptions of JTS, provided to us by JTS management; (viii) made inquiries
regarding and discussed the Merger and the draft of the Reorganization Agreement
and other matters related thereto with the Company's counsel; and (ix) performed
such other analyses and examinations as we have deemed appropriate.
 
     In connection with our review, we have assumed and relied upon the accuracy
and completeness of the foregoing information and we have not assumed any
responsibility for independent verification of such information. With respect to
the financial forecasts provided to us as described above, we have assumed for
purposes of our opinion that such forecasts have been reasonably prepared on
bases reflecting the best
<PAGE>   231
 
available estimates and judgments of the management of JTS at the time of
preparation as to the future financial performance of JTS, and, except as
described below, that they provide a reasonable basis upon which we can form our
opinion. For purposes of our opinion and with the agreement of management of the
Company, we have adjusted the financial forecasts for JTS provided to us by its
management to reflect more conservative assumptions regarding future results of
operations. We have also assumed that there have been no material changes in the
Company's or JTS' assets, financial condition, results of operations, business
or prospects since the respective dates of their last financial statements made
available to us. We have relied on advice of counsel and independent accountants
to the Company as to all legal and financial reporting matters with respect to
the Company, the Merger and the draft of the Reorganization Agreement. In
addition, we have not assumed responsibility for making an independent
evaluation, appraisal or physical inspection of the assets or individual
properties of the Company or JTS, nor have we been furnished with any such
appraisals. Finally, our opinion is based on economic, monetary and market and
other conditions as in effect on, and the information made available to us as
of, the date hereof.
 
     We have further assumed, with your consent, that the Merger will be
consummated in accordance with the terms described in the draft of the
Reorganization Agreement without any amendments thereto, and without waiver by
the Company or JTS of any of the conditions to their respective obligations
thereunder.
 
     We have, in the ordinary course of our business, previously performed
various investment banking services for JTS.
 
     Based upon the foregoing and in reliance thereon, it is our opinion as
investment bankers that the Exchange Ratio to be paid by Newco pursuant to the
Merger is fair to the Company from a financial point of view, as of the date
hereof.
 
     This opinion is directed to the Board of Directors of the Company and is
not a recommendation to any shareholder as to how such shareholder should vote
with respect to the Merger. This opinion may not be used or referred to by the
Company, or quoted or disclosed to any person in any manner, without our prior
written consent, which consent is hereby given to its inclusion in any proxy
statement or prospectus filed with the Securities and Exchange Commission in
connection with the Merger. In furnishing this opinion, we do not admit that we
are experts within the meaning of the term "experts" as used in the Securities
Act of 1933, as amended, and the rules and regulations promulgated thereunder
(the "Securities Act"), nor do we admit that this opinion constitutes a report
or valuation within the meaning of Section 11 of the Securities Act.
 
                                          Very truly yours,

                        DELAWARE GENERAL CORPORATION LAW
                                APPRAISAL RIGHTS
 
     Section 262 Appraisal Rights.  (a) Any stockholder of a corporation of this
State who holds shares of stock on the date of the making of a demand pursuant
to subsection (d) of this section with respect to such shares, who continuously
holds such shares through the effective date of the merger or consolidation, who
has otherwise complied with subsection (d) of this section and who has neither
voted in favor of the merger or consolidation nor consented thereto in writing
pursuant to sec. 228 of this title shall be entitled to an appraisal by the
Court of Chancery of the fair value of his shares of stock under the
circumstances described in subsections (b) and (c) of this section. As used in
this section, the word "stockholder" means a holder of record of stock in a
stock corporation and also a member of record of a nonstock corporation; the
words "stock" and "share" mean and include what is ordinarily meant by those
words and also membership or membership interest of a member of a nonstock
corporation.
 
     (b) Appraisal rights shall be available for the shares of any class or
series of stock of a constituent corporation in a merger or consolidation to be
effected pursuant to sec.sec. 251, 252, 254, 257, 258 or 263 of this title:
 
          (1) Provided, however, that no appraisal rights under this section
     shall be available for the shares of any class or series of stock which, at
     the record date fixed to determine the stockholders entitled to receive
     notice of and to vote at the meeting of stockholders to act upon the
     agreement of merger or consolidation, were either (i) listed on a national
     securities exchange or (ii) held of record by more than 2,000 stockholders;
     and further provided that no appraisal rights shall be available for any
     shares of stock of the constituent corporation surviving a merger if the
     merger did not require for its approval the vote of the stockholders of the
     surviving corporation as provided in subsection (f) of sec. 251 of this
     title.
 
          (2) Notwithstanding paragraph (1) of this subsection, appraisal rights
     under this section shall be available for the shares of any class or series
     of stock of a constituent corporation if the holders thereof are required
     by the terms of an agreement of merger or consolidation pursuant to
     sec.sec. 251, 252, 254, 257, 258 and 263 of this title to accept for such
     stock anything except: a. Shares of stock of the corporation surviving or
     resulting from such merger or consolidation; b. Shares of stock of any
     other corporation which at the effective date of the merger or
     consolidation will be either listed on a national securities exchange or
     held of record by more than 2,000 stockholders; c. Cash in lieu of
     fractional shares of the corporations described in the foregoing
     subparagraphs a. and b. of this paragraph; or d. Any combination of the
     shares of stock and cash in lieu of fractional shares described in the
     foregoing subparagraphs a., b. and c. of this paragraph.
 
          (3) In the event all of the stock of a subsidiary Delaware corporation
     party to a merger effected under sec. 253 of this title is not owned by the
     parent corporation immediately prior to the merger, appraisal rights shall
     be available for the shares of the subsidiary Delaware corporation.
 
     (c) Any corporation may provide in its certificate of incorporation that
appraisal rights under this section shall be available for the shares of any
class or series of its stock as a result of an amendment to its certificate of
incorporation, any merger or consolidation in which the corporation is a
constituent corporation or the sale of all or substantially all of the assets of
the corporation. If the certificate of incorporation contains such a provision,
the procedures of this section, including those set forth in subsections (d) and
(e) of this section, shall apply as nearly as practicable.
 
     (d) Appraisal rights shall be perfected as follows:
 
          (1) If a proposed merger or consolidation for which appraisal rights
     are provided under this section is to be submitted for approval at a
     meeting of stockholders, the corporation, not less than 20 days prior to
     the meeting, shall notify each of its stockholders who was such on the
     record date for such meeting with respect to shares for which appraisal
     rights are available pursuant to subsection (b) or (c) hereof, that
 
                                        1
<PAGE>   234
 
     appraisal rights are available for any or all of the shares of the
     constituent corporations, and shall include in such notice a copy of this
     section. Each stockholder electing to demand the appraisal of his shares
     shall deliver to the corporation, before the taking of the vote on the
     merger or consolidation, a written demand for appraisal of his shares. Such
     demand will be sufficient if it reasonably informs the corporation of the
     identity of the stockholder and that the stockholder intends thereby to
     demand the appraisal of his shares. A proxy or vote against the merger or
     consolidation shall not constitute such a demand. A stockholder electing to
     take such action must do so by a separate written demand as herein
     provided. Within 10 days after the effective date of such merger or
     consolidation, the surviving or resulting corporation shall notify each
     stockholder of each constituent corporation who has complied with this
     subsection and has not voted in favor of or consented to the merger or
     consolidation of the date that the merger or consolidation has become
     effective; or
 
          (2) If the merger or consolidation was approved pursuant to sec. 228
     or 253 of this title, the surviving or resulting corporation, either before
     the effective date of the merger or consolidation or within 10 days
     thereafter, shall notify each of the stockholders entitled to appraisal
     rights of the effective date of the merger or consolidation and that
     appraisal rights are available for any or all of the shares of the
     constituent corporation, and shall include in such notice a copy of this
     section. The notice shall be sent by certified or registered mail, return
     receipt requested, addressed to the stockholder at his address as it
     appears on the records of the corporation. Any stockholder entitled to
     appraisal rights may, within 20 days after the date of mailing of the
     notice, demand in writing from the surviving or resulting corporation the
     appraisal of his shares. Such demand will be sufficient if it reasonably
     informs the corporation of the identity of the stockholder and that the
     stockholder intends thereby to demand the appraisal of his shares.
 
          (e) Within 120 days after the effective date of the merger or
     consolidation, the surviving or resulting corporation or any stockholder
     who has complied with subsections (a) and (d) hereof and who is otherwise
     entitled to appraisal rights, may file a petition in the Court of Chancery
     demanding a determination of the value of the stock of all such
     stockholders. Notwithstanding the foregoing, at any time within 60 days
     after the effective date of the merger or consolidation, any stockholder
     shall have the right to withdraw his demand for appraisal and to accept the
     terms offered upon the merger or consolidation. Within 120 days after the
     effective date of the merger or consolidation, any stockholder who has
     complied with the requirements of subsections (a) and (b) hereof, upon
     written request, shall be entitled to receive from the corporation
     surviving the merger or resulting from the consolidation a statement
     setting for the aggregate number of shares not voted in favor of the merger
     or consolidation and with respect to which demands for appraisal have been
     received and the aggregate number of holders of such shares. Such written
     statement shall be mailed to the stockholder within 10 days after his
     written request or such a statement is received by the surviving or
     resulting corporation or within 10 days after expiration of the period for
     delivery of demands for appraisal under subsection (d) hereof, whichever is
     later.
 
          (f) Upon the filing of any such petition by a stockholder, service of
     a copy thereof shall be made upon the surviving or resulting corporation,
     which shall within 20 days after such service file in the office of the
     Register in Chancery in which the petition was filed a duly verified list
     containing the names and addresses of all stockholders who have demanded
     payment for their shares and with whom agreements as to the value of their
     shares have not been reached by the surviving or resulting corporation. If
     the petition shall be filed by the surviving or resulting corporation, the
     petition shall be accompanied by such a duly verified list. The Register in
     Chancery, if so ordered by the Court, shall give notice of the time and
     place fixed for the hearing of such petition by registered or certified
     mail to the surviving or resulting corporation and to the stockholders
     shown on the list at the addresses therein stated. Such notice shall also
     be given by one or more publications at least one week before the day of
     the hearing, in a newspaper of general circulation published in the City of
     Wilmington, Delaware, or such publication as the Court deems advisable. The
     forms of the notices by mail and by publication shall be approved by the
     Court, and the costs thereof shall be borne by the surviving or resulting
     corporation.
 
          (g) At the hearing on such petition, the Court shall determine the
     stockholders who have complied with this section and who have become
     entitled to appraisal rights. The Court may require the
 
                                        2
<PAGE>   235
 
     stockholders who have demanded an appraisal for their shares and who hold
     stock represented by certificates to submit their certificates of stock to
     the Register in Chancery for notation thereon of the pendency of the
     appraisal proceedings; and if any stockholder fails to comply with such
     direction, the Court may dismiss the proceedings as to such stockholder.
 
          (h) After determining the stockholders entitled to an appraisal, the
     Court shall appraise the shares, determining their fair value exclusive of
     any element of value arising from the accomplishment or expectation of the
     merger or consolidation, together with a fair rate of interest, if any, to
     be paid upon the amount determined to be the fair value. In determining
     such fair value, the Court shall take into account all relevant factors. In
     determining the fair rate of interest, the Court may consider all relevant
     factors, including the rate of interest which the surviving or resulting
     corporation would have had to pay to borrow money during the pendency of
     the proceeding. Upon application by the surviving or resulting corporation
     or by any stockholder entitled to participate in the appraisal proceeding,
     the Court may, in its discretion, permit discovery or other pretrial
     proceedings and may proceed to trial upon the appraisal prior to the final
     determination of the stockholder entitled to an appraisal. Any stockholder
     whose name appears on the list filed by the surviving or resulting
     corporation pursuant to subsection (f) of this section and who has
     submitted his certificates of stock to the Register in Chancery, if such is
     required, may participate fully in all proceeds until it is finally
     determined that he is not entitled to appraisal rights under this section.
 
          (i) The Court shall direct the payment of the fair value of the
     shares, together with interest, if any, by the surviving or resulting
     corporation to the stockholders entitled thereto. Interest may be simple or
     compound, as the Court may direct. Payment shall be so made to each such
     stockholder, in the case of holders of uncertificated stock forthwith, and
     the case of holders of shares represented by certificates upon the
     surrender to the corporation of the certificates representing such stock.
     The Court's decree may be enforced as other decrees in the Court of
     Chancery may be enforced, whether such surviving or resulting corporation
     be a corporation of this State or of any state.
 
          (j) The costs of the proceeding may be determined by the Court and
     taxed upon the parties as the Court deems equitable in the circumstances.
     Upon application of a stockholder, the Court may order all or a portion of
     the expenses incurred by any stockholder in connection with the appraisal
     proceeding, including, without limitation, reasonable attorney's fees and
     the fees and expenses of experts, to be charged pro rata against the value
     of all the shares entitled to an appraisal.
 
          (k) From and after the effective date of the merger or consolidation,
     no stockholder who has demanded his appraisal rights as provided in
     subsection (d) of this section shall be entitled to vote such stock for any
     purpose or to receive payment of dividends or other distributions on the
     stock (except dividends or other distributions payable to stockholder of
     record at a date which is prior to the effective date for the merger or
     consolidation); provided, however, that if no petition for an appraisal
     shall be filed within the time provided in subsection (e) of this section,
     or if such stockholder shall deliver to the surviving or resulting
     corporation a written withdrawal of his demand for an appraisal and an
     acceptance of the merger or consolidation, either within 60 days after the
     effective date of the merger or consolidation as provided in subsection (e)
     of this section or thereafter with the written approval of the corporation,
     then the right of such stockholder to an appraisal shall cease.
     Notwithstanding the foregoing no appraisal proceeding in the Court of
     Chancery shall be dismissed as to any stockholder without the approval of
     the Court, and such approval may be conditioned upon such terms as the
     Court deems just.
 
          (l) The shares of the surviving or resulting Corporation to which the
     shares of such objecting stockholders would have been converted had they
     assented to the merger or consolidation shall have the status of authorized
     and unissued shares of the surviving or resulting corporation.

                     GENERAL CORPORATION LAW OF CALIFORNIA
                               DISSENTERS RIGHTS
 
     SECTION 1300. Right to Require Purchase; "Dissenting Shares" and
"Dissenting Shareholder" Defined.
 
     (a) If the approval of the outstanding shares (Section 152) of a
corporation is required for a reorganization under subdivisions (a) and (b) or
subdivision (e) of Section 1201, each shareholder of such corporation entitled
to vote on the transaction and each shareholder of a subsidiary corporation in a
short-form merger may, by complying with this chapter, require the corporation
in which the shareholder holds shares to purchase for cash at their fair market
value the shares owned by the shareholder which are dissenting shares as defined
in subdivision (b). The fair market value shall be determined as of the day
before the first announcement of the terms of the proposed reorganization or
short-form merger, excluding any appreciation or depreciation in consequence of
the proposed action. but adjusted for any stock split or share dividend which
becomes effective thereafter.
 
     (b) As used in this chapter, "dissenting shares" means shares which come
within all of the following descriptions:
 
          (1) Which were not immediately prior to the reorganization or
     short-form merger either (A) listed on any national securities exchange
     certified by the Commissioner of Corporations under subdivision (0) of
     Section 25100 or (B) listed on the list of OTC margin stocks issued by the
     Board of Governors of the Federal Reserve System, and the notice of meeting
     of shareholders to act upon the reorganization summarizes this section and
     Sections 1301, 1302, 1303 and 1304; provided, however, that this provision
     does not apply to any shares with respect to which there exists any
     restriction on transfer imposed by the corporation or by any law or
     regulation; and provided, further, that this provision does not apply to
     any class of shares described in subparagraph (A) or (B) if demands for
     payment are filed with respect to five percent or more of the outstanding
     shares of that class.
 
          (2) Which were outstanding on the date for the determination of
     shareholders entitled to vote on the reorganization and (A) were not voted
     in favor of the reorganization or, (B) if described in subparagraph (A) or
     (B) of paragraph (1) (without regard to the provisos in that paragraph),
     were voted against the reorganization, or which were held of record on the
     effective date of a short-form merger-. provided, however, that
     subparagraph (A) rather than subparagraph (B) of this paragraph applies in
     any case where the approval required by Section 1201 is sought by written
     consent rather than at a meeting.
 
          (3) Which the dissenting shareholder has demanded that the corporation
     purchase at their fair market value, in accordance with Section 1301.
 
          (4) Which the dissenting shareholder has submitted for endorsement, in
     accordance with Section 1301.
 
     (c) As used in this chapter, "dissenting shareholder" means the
recordholder of dissenting shares and includes a transferee of record.
 
     SECTION 1301.  Demand for Purchase.
 
     (a) If, in the case of a reorganization, any shareholders of a corporation
have a right under Section 1300, subject to compliance with paragraphs (3) and
(4) of subdivision (b) thereof, to require the corporation to purchase their
shares for cash, such corporation shall mail to each such shareholder a notice
of the approval of the reorganization by its outstanding shares (Section 152)
within ten (10) days alter the date of such approval accompanied by a copy of
Sections 1300, 1302, 1303, 1304 and this section, a statement of the price
determined by the corporation to represent the fair market value of the
dissenting shares, and a brief description of the procedure to be followed if
the shareholder desires to exercise the shareholder's fight under such sections.
The statement of price constitutes an offer by the corporation to purchase at
the price stated any
 
                                        1
<PAGE>   238
 
dissenting shares as defined in subdivision (b) of Section 1300, unless they
lose their status as dissenting shares under Section 1309.
 
     (b) Any shareholder who has a right to require the corporation to purchase
the shareholder's shares for cash under Section 1300, subject to compliance with
paragraphs (3) and (4) of subdivision (b) thereof, and who desires the
corporation to purchase such shares shall make written demand upon the
corporation for the purchase of such shares and payment to the shareholder in
cash of their fair market value. The demand is not effective for any purpose
unless it is received by the corporation or any transfer agent thereof (1) in
the case of shares described in clause (i) or (ii) of paragraph (1) of
subdivision (b) of Section 1300 (without regard to the provisos in that
paragraph), not later than the date of the shareholders' meeting to vote upon
the reorganization, or (2) in any other case within thirty (30) days after the
date on which the notice of the approval by the outstanding shares pursuant to
subdivision (a) or the notice pursuant to subdivision (i) of Section 1110 was
mailed to the shareholder.
 
     (c) The demand shall state the number and class of the shares held of
record by the shareholder which the shareholder demands that the corporation
purchase and shall contain a statement of what such shareholder claims to be the
fair market value of those shares as of the day before the announcement of the
proposed reorganization or short-form merger. The statement of fair market value
constitutes an offer by the shareholder to sell the shares at such price.
 
     SECTION 1302.  Endorsement of Shares.
 
     Within thirty (30) days after the date on which notice of the approval by
the outstanding shares or the notice pursuant to subdivision (i) of Section 1110
was mailed to the shareholder. the shareholder shall submit to the corporation
at its principal office or at the office of any transfer agent thereof, (a) if
the shares are certificated securities, the shareholder's certificates
representing any shares which the shareholder demands that the corporation
purchase, to be stamped or endorsed with a statement that the shares are
dissenting shares or to be exchanged for certificates of appropriate
denomination so stamped or endorsed or (b) if the shares are uncertificated
securities, written notice of the number of shares which the shareholder demands
that the corporation purchase. Upon subsequent transfers of the dissenting
shares on the books of the corporation, the new certificates, initial
transaction statement, and other written statements issued therefor shall bear a
like statement, together with the name of the original dissenting holder of the
shares.
 
     SECTION 1303.  Agreed Price; Time for Payment.
 
     (a) If the corporation and the shareholder agree that the shares are
dissenting shares and agree upon the price of the shares, the dissenting
shareholder is entitled to the agreed price with interest thereon at the legal
rate on judgments from the date of the agreement. Any agreements fixing the fair
market value of any dissenting shares as between the corporation and the holders
thereof shall be filed with the secretary of the corporation.
 
     (b) Subject to the provisions of Section 1306, payment of the fair market
value of dissenting shares shall be made within thirty (30) days after the
amount thereof has been agreed or within thirty (30) days after any statutory or
contractual conditions to the reorganization are satisfied, whichever is later,
and in the case of certificated securities, subject to surrender of the
certificates therefor, unless provided otherwise by agreement.
 
     SECTION 1304.  Dissenter's Action to Enforce Payment.
 
     (a) If the corporation denies that the shares are dissenting shares, or the
corporation and the shareholder fail to agree upon the fair market value of the
shares, then the shareholder demanding purchase of such shares as dissenting
shares or any interested corporation, within six (6) months after the date on
which notice of the approval by the outstanding shares (Section 152) or notice
pursuant to subdivision (i) of Section 1110 was mailed to the shareholder, but
not thereafter, may file a complaint in the superior court of the proper county
praying the court to determine whether the shares are dissenting shares or the
fair market value of the dissenting shares or both or may intervene in any
action pending on such a complaint.
 
     (b) Two or more dissenting shareholders may join as plaintiffs or be joined
as defendants in any such action and two or more such actions may be
consolidated.
 
                                        2
<PAGE>   239
 
     (c) On the trial of the action, the court shall determine the issues. If
the status of the shares as dissenting shares is in issue, the court shall first
determine that issue. If the fair market value of the dissenting shares is in
issue, the court shall determine, or shall appoint one or more impartial
appraisers to determine, the fair market value of the shares.
 
     SECTION 1305.  Appraiser's Report; Payment; Costs.
 
     (a) If the court appoints an appraiser or appraisers, they shall proceed
forthwith to determine the fair market value per share. Within the time fixed by
the court, the appraisers, or a majority of them, shall make and file a report
in the office of the clerk of the court. Thereupon, on the motion of any party,
the report shall be submitted to the court and considered on such evidence as
the court considers relevant. If the court finds the report reasonable, the
court may confirm it.
 
     (b) If a majority of the appraisers appointed fail to make and file a
report within ten (10) days from the date of their appointment or within such
further time as may be allowed by the court or the report is not confirmed by
the court, the court shall determine the fair market value of the dissenting
shares.
 
     (c) Subject to the provisions of Section 1306, judgment shall be rendered
against the corporation for payment of an amount equal to the fair market value
of each dissenting share multiplied by the number of dissenting shares which any
dissenting shareholder who is a party, or who has intervened, is entitled to
require the corporation to purchase, with interest thereon at the legal rate
from the date on which judgment was entered.
 
     (d) Any such judgment shall be payable forthwith with respect to
uncertificated securities and, with respect to certificated securities, only
upon the endorsement and delivery to the corporation of the certificates for the
shares described in the judgment. Any party may appeal from the judgment.
 
     (e) The costs of the action, including reasonable compensation to the
appraisers to be fixed by the court, shall be assessed or apportioned as the
court considers equitable, but, if the appraisal exceeds the price offered by
the corporation, the corporation shall pay the costs (including in the
discretion of the court attorneys' fees, fees of expert witnesses and interest
at the legal rate on judgments from the date of compliance with Sections 1300,
1301 and 1302 if the value awarded by the court for the shares is more than 125
percent of the price offered by the corporation under subdivision (a) of Section
1301).
 
     SECTION 1306.  Dissenting Shareholder's Status as Creditor.
 
     To the extent that the provisions of Chapter 5 prevent the payment to any
holders of dissenting shares of their fair market value, they shall become

     SECTION 1309.  Termination of Dissenting Shareholder Status.
 
     Dissenting shares lose their status as dissenting shares and the holders
thereof cease to be dissenting shareholders and cease to be entitled to require
the corporation to purchase their shares upon the happening of any of the
following:
 
          (a) The corporation abandons the reorganization. Upon abandonment of
     the reorganization, the corporation shall pay on demand to any dissenting
     shareholder who has initiated proceedings in good faith under this chapter
     all necessary expenses incurred in such proceedings and reasonable
     attorneys' fees.
 
          (b) The shares are transferred prior to their submission for
     endorsement in accordance with Section 1302 or are surrendered for
     conversion into shares of another class in accordance with the articles.
 
          (c) The dissenting shareholder and the corporation do not agree upon
     the status of the shares as dissenting shares or upon the purchase price of
     the shares, and neither files a complaint or intervenes in a pending action
     as provided in Section 1304, within six (6) months after the date on which
     notice of the approval by the outstanding shares or notice pursuant to
     subdivision (i) of Section 1110 was mailed to the shareholder.
 
          (d) The dissenting shareholder, with the consent of the corporation,
     withdraws the shareholder's demand for purchase of the dissenting shares.
 
     SECTION 1310.  Suspension of Proceedings for Payment Pending Litigation.
 
     If litigation is instituted to test the sufficiency or regularity of the
votes of the shareholders in authorizing a reorganization, any proceedings under
Sections 1304 and 1305 shall be suspended until final determination of such
litigation.
 
     SECTION 1311.  Exempt Shares.
 
     This chapter, except Section 1312, does not apply to classes of shares
whose terms and provisions specifically set forth the amount to be paid in
respect to such shares in the event of a reorganization or merger.
 
     SECTION 1312.  Attacking Validity of Reorganization or Merger.
 
     (a) No shareholder of a corporation who has a right under this chapter to
demand payment of cash for the shares held by the shareholder shall have any
right at law or in equity to attack the validity of the reorganization or
short-form merger, or to have the reorganization or short-form merger set aside
or rescinded, except in an action to test whether the number of shares required
to authorize or approve the reorganization have been legally voted in favor
thereof, but any holder of shares of a class whose terms and provisions
specifically set forth the amount to be paid in respect to them in the event of
a reorganization or short-form merger is entitled to payment in accordance with
those terms and provisions or, if the principal terms of the reorganization are
approved pursuant to subdivision (b) of Section 1202, is entitled to payment in
accordance with the terms and provisions of the approved reorganization.
 
     (b) If one of the parties to a reorganization or short-form merger is
directly or indirectly controlled by, or under common control with, another
party to the reorganization or short-form merger, subdivision (a) shall not
apply to any shareholder of such party who has not demanded payment of cash for
such shareholder's shares pursuant to this chapter, but if the shareholder
institutes any action to attack the validity of the reorganization or short-form
merger or to have the reorganization or short-form merger set aside or
rescinded, the shareholder shall not thereafter have any right to demand payment
of cash for the shareholder's shares pursuant to this chapter. The court in any
action attacking the validity of the reorganization or short-form merger or to
have the reorganization or short-form merger set aside or rescinded shall not
restrain or enjoin the consummation of the transaction except upon ten (10)
days' prior notice to the corporation and upon a determination by the court that
clearly no other remedy will adequately protect the complaining shareholder or
the class of shareholders of which such shareholder is a member.

     (c) If one of the parties to a reorganization or short-form merger is
directly or indirectly controlled by or under common control with, another party
to the reorganization or short-form merger, in any action to attack the validity
of the reorganization or short-form merger or to have the reorganization or
short-form merger set aside or rescinded, (1) a party to a reorganization or
short-form merger which controls another party to the reorganization or
short-form merger shall have the burden of proving that the transaction is just
and reasonable as to the shareholders of the controlled party, and (2) a person
who controls two or more parties to a reorganization shall have the burden of
proving that the transaction is just and reasonable as to the shareholders of
any party so controlled.
