shall file a further amendment which specifically states that this Registration
Statement shall thereafter become effective in accordance with Section 8(a) of

Storage Systems group common stock and Hard Disk Drive group common stock for
your shares of Meridian common stock. The actual number of shares of DLT &

the performance of Quantum's DLT & Storage Systems group and Hard Disk Drive
group.

close of business on August 4, 1999. The merger cannot be completed unless

document. Your vote is very important. Whether or not you plan to attend the
special meeting in person, please take the time to vote by completing and

card without indicating how you want to vote, your proxy will count as a vote

all matters even if you have previously returned a proxy card.

  This proxy statement/prospectus provides you with detailed information about

                             QUESTIONS AND ANSWERS
                       ABOUT THE QUANTUM/MERIDIAN MERGER

Q: As a Meridian stockholder, what will I receive in the merger?

A: You will receive shares of Quantum DLT & Storage Systems group common stock
   and Hard Disk Drive group common stock for your Meridian common stock. For
   the shares of DLT & Storage Systems group common stock you receive, you will
   also receive half as many shares of Hard Disk Drive group stock. The two
   classes of Quantum common stock are intended to reflect separately the
   performance of Quantum's DLT & Storage Systems group and Hard Disk Drive
   group. A class of common stock intended to "track" a separate group of one
   company is commonly referred to as a "tracking stock". The actual number of
   shares of Quantum DLT & Storage Systems group common stock and Hard Disk
   Drive group common stock that will be issued to you for each share of
   Meridian's common stock that you own will be determined by the sum of
   (1) the average of the closing sale price of one share of DLT & Storage
   Systems group common stock for a specified period before the special meeting
   and (2) the average of one half of the closing sale price of one share of
   Hard Disk Drive group common stock over the same period. If the resulting
   sum of the average prices is greater than or equal to $14.00 but less than
   or equal to $20.00, then the exchange ratio will be 0.489 such that each
   share of Meridian common stock will convert into 0.489 of a share of Quantum
   DLT & Storage Systems group common stock and half as many shares (or 0.2445
   of a share) of Hard Disk Drive group common stock. If the combined average
   price is less than $14.00, then the exchange ratio will be determined by
   dividing $7.00 by the combined average stock price such that the number of
   shares of DLT & Storage Systems group common stock issued for each share of
   Meridian common stock will equal the exchange ratio and the number of shares
   of Hard Disk Drive group common stock issued for each share of Meridian
   common stock will be one-half of the exchange ratio. If the combined average
   stock price is greater than $20.00, then the exchange ratio will be
   determined by dividing $10.00 by the combined average stock price such that
   the number of shares of DLT & Storage Systems group common stock issued for
   each share of Meridian common stock will equal the exchange ratio and the
   number of shares of Hard Disk Drive group common stock issued for each share
   of Meridian common stock will be one-half of the exchange ratio. For an
   estimate of the exchange ratio as of any date prior to and including the
   date on which the exchange ratio is finally determined please call 1-888-
   897-0079.

  No fractional shares will be issued. You will receive cash for any
  fractional share you would otherwise receive. The dollar amount you receive
  for a fraction of a share of either DLT & Storage Systems group or Hard
  Disk Drive group common stock will equal that fraction multiplied by the
  average of the closing price of a share of that class of common stock, for
  the five trading day period ending two trading days prior to the Meridian
  special meeting.

Q: What happens to options to purchase Meridian common stock as a result of the
   merger?

A: Each option to purchase Meridian common stock will convert into an option to
   purchase shares of Quantum DLT & Storage Systems group common stock and Hard
   Disk Drive group common stock at the same ratio at which Meridian common
   stock is exchanged for such classes of Quantum common stock. For example, if
   the average closing prices of the classes of Quantum common stock before the
   special meeting results in a 0.489 exchange ratio such that each share of
   Meridian common stock is exchanged for 0.489 of a share of Quantum DLT &
   Storage Systems group common stock and half as many (or 0.2445 of a share)
   of Hard Disk Drive group common stock, then each option to purchase Meridian
   common stock will be converted into an option to purchase 48.9% as many
   shares of Quantum DLT & Storage Systems group common stock and 24.45% as
   many shares of Hard Disk Drive group common stock, at an adjusted exercise
   price. The exercise price for the DLT & Storage Systems group stock options
   will be calculated by multiplying the exercise price of your existing
   Meridian option by a fraction, the numerator of which is .733 and the
   denominator

                                      iii
<PAGE>

   of which is the exchange ratio. The exercise price for the Hard Disk Drive
   group stock options will be calculated by multiplying the exercise price of
   your existing Meridian option by a fraction, the numerator of which is .534
   and the denominator of which is the exchange ratio. In the above example,
   if you have an option to purchase 10,000 shares of Meridian common stock at
   an exercise price of $10.00 for an aggregate exercise price of $100,000,
   after the merger you will have an option or warrant to purchase 4,890
   shares of Quantum DLT & Storage Systems group common stock at an exercise
   price of $14.99 and 2,445 shares of Hard Disk Drive group common stock at
   an exercise price of $10.92 for an aggregate exercise price of $100,000.

Q: What are the tax consequences to stockholders of the merger?

A: We have structured the merger with the intent that the merger will be a
   tax-free reorganization for federal income tax purposes. Assuming that the
   merger constitutes a reorganization, you will not recognize gain or loss on
   the exchange of your Meridian stock for DLT & Storage Systems group common
   stock and Hard Disk Drive group common stock, except that you may be taxed
   on cash received for a fractional share. However, the tax treatment of
   tracking stock is subject to uncertainties. See the sections entitled "Risk
   Factors Relating to the Merger--There is a Lack of Certainty that the
   Merger will be Tax-Free" beginning on page 14 and "Recent Clinton
   Administration Proposal Could Result in Taxation of Issuance of Tracking
   Stock" beginning on page 20. To review the tax consequences to Quantum and
   Meridian stockholders in greater detail, see the section entitled "Approval
   of the Merger and Related Transactions--Material Federal Income Tax
   Consequences" beginning on page 37 of this proxy statement/prospectus.

Q: Are there risks I should consider in deciding whether to vote for the
   merger?

A: Yes. For example, there is uncertainty regarding tax treatment of the
   merger as described above. Another risk is that the implied value per share
   of Meridian common stock in the merger will not exceed $10.00 and can be as
   low as $6.85 regardless of changes in the market price of the DLT & Storage
   Systems group common stock and Hard Disk Drive group common stock. We urge
   you to obtain current market quotations of the DLT & Storage Systems group
   common stock and Hard Disk Drive group common stock and Meridian common
   stock. In evaluating the merger, you should carefully consider these and
   other risks discussed in the section entitled "Risk Factors" on page 12.

Q: Why am I being asked to ratify the 1997 reincorporation?

A: In 1997, Meridian's board of directors solicited the approval of its
   shareholders to reincorporate Meridian in Delaware in order to obtain the
   benefits and advantages of Delaware corporate law. The reincorporation was
   approved by a majority of the votes cast on the proposal, which Meridian
   believed was sufficient to effect the reincorporation, and Meridian
   effected its reincorporation in Delaware. In connection with the due
   diligence investigation related to the merger of Meridian with Quantum, it
   was discovered that the proxy statement sent to the Meridian stockholders
   in connection with the reincorporation proposal incorrectly set forth the
   vote required under California law to obtain stockholder approval for the
   reincorporation proposal, and that the 1997 reincorporation proposal failed
   to receive the requisite number of votes under California law. In order to
   cure the failure to obtain the requisite stockholder vote in connection
   with Meridian's 1997 reincorporation, Meridian is now asking its
   stockholders to ratify the 1997 reincorporation.

Q: What are the effects of a failure to ratify the 1997 reincorporation?

A: The failure to obtain the sufficient stockholder vote to ratify the 1997
   reincorporation would not by itself result in the rescission or
   nullification of the 1997 reincorporation, but the 1997 reincorporation is
   vulnerable to challenge and Quantum would be entitled to terminate the
   merger agreement at its option.

Q: Does Meridian's board of directors recommend voting in favor of the merger
   and the ratification of the 1997 reincorporation?

A: Yes. After careful consideration, Meridian's board of directors recommends
   that its

                                      iv
<PAGE>

   stockholders vote in favor of the merger agreement and the proposed merger
   and the ratification of the 1997 reincorporation. For a more complete
   description of the recommendation of the board of directors of Meridian,
   see the section entitled "Approval of the Merger and Related Transactions--
   Meridian's Reasons for the Merger" beginning on page 30.

Q: If I am not going to attend the stockholder meeting, should I return my
   proxy card instead?

A: Yes. Please fill out and sign your proxy card and mail it to us in the
   enclosed return envelope as soon as possible. Returning your proxy card
   ensures that your shares will be represented at the special meeting. For
   information about submitting proxies in a timely manner, including
   instructions for any stockholder who wishes to wait until the exchange
   ratio is finally determined before voting, please call Corporate Investor
   Communications, Inc. at 1-888-897-0079.

Q: What do I do if I want to change my vote?

A: Send in a later-dated, signed proxy card to Meridian's corporate secretary
   before the special meeting or attend the special meeting in person and
   vote.

Q: Should I send in my stock certificates now?

A: No. After the merger is completed, we will send Meridian stockholders
   written instructions for exchanging their stock certificates.

Q: If my shares are held in "street name" by my broker, will my broker vote my
   shares for me?

A: Your broker will vote your shares only if you provide instructions on how
   to vote by following the information provided to you by your broker. For a
   more complete description of voting shares held in "street name," see the
   section entitled "The Meridian Special Meeting--Voting of Proxies"
   beginning on page 26.

Q: Am I entitled to dissenters' or appraisal rights?

A: Under Delaware law, holders of Meridian common stock are not entitled to
   dissenters' or appraisal rights in the merger or in the ratification of the
   1997 reincorporation.

Q: Whom should I call with questions?

A: You should call Meridian's investor relations department at (831) 438-3100
   with questions about the merger and Corporate Investor Communications, Inc.
   at 1-888-897-0079 to receive an estimate of the exchange ratio as of any
   date prior to and including the date on which the exchange ratio is finally
   determined or for instructions about submitting your proxy. You may also
   obtain additional information about Quantum and Meridian from documents
   each of us files with the Securities and Exchange Commission by following
   the instructions in the section entitled "Where you can find more
   information" on page 102.

Q: When do you expect the merger to be completed?

A: We are working toward completing the merger as quickly as possible.
   Assuming that our companies satisfy or waive all of the conditions to
   closing contained in the merger agreement, including the ratification of
   the 1997 reincorporation, we anticipate that the merger will occur on or
   before September 10, 1999.

                                 The Companies

Quantum Corporation
500 McCarthy Blvd.
Milpitas, California 95053
(408) 894-4000

  Quantum operates its business through two separate business groups: the DLT &
Storage Systems group and the Hard Disk Drive group. The DLT & Storage Systems
group designs, develops, manufactures, licenses and markets DLTtape(TM) drives,
DLTtape media cartridges and tape libraries which are used to back-up large
amounts of data stored on network servers. Digital Linear Tape, or DLTtape, is
the DLT & Storage Systems group's half-inch tape technology that is the de
facto industry standard for data back-up in the mid-range network server
market, which includes network servers priced between $10,000 and $500,000. The
DLT & Storage Systems group's DLTtape media cartridges are manufactured
primarily by licensed third party manufacturers. The Hard Disk Drive group
designs, develops and markets a diversified product portfolio of hard disk
drives featuring leading-edge technology. A hard disk drive is a storage device
found in most computers that stores data on multiple rotating magnetic disks
that provide fast access to data that must be readily available to computer
users. The Hard Disk Drive group's hard disk drives are designed for the
desktop market and the high-end hard disk drive market which requires faster
and higher capacity disk drives--as well as the emerging market for hard disk
drives specially designed for consumer electronics applications such as new TV
recording devices. The Hard Disk Drive group has been the leading volume
supplier of hard disk drives for the desktop market for each of the past six
years. According to Dataquest, the Hard Disk Drive group's market share in the
desktop market has grown from 3% in 1990 to an industry leading 22% in 1998.

Meridian Data, Inc.
5615 Scotts Valley Drive
Scotts Valley, California 95006
(831) 438-3100

  Meridian is a developer and manufacturer of network storage solutions.
Meridian provides network attached storage servers for workgroups based on
optical disk and hard disk storage, and CD-ROM enterprise networking servers
and subsystems. In 1998, Meridian announced its first network attached storage
server product based on hard drive technology, the Snap! Server(TM). The Snap!
Server allows small and medium-sized businesses and corporate workgroups to
increase storage capacity on their network with minimal hardware expertise or
time expenditure. For more information on Meridian, see "Where You Can Find
More Information" on Page 102.

                       Meridian's Reasons for the Merger

  The Meridian board believes that the merger with Quantum will be beneficial
to Meridian stockholders for the following reasons:

  .  Meridian's business plan is centered around the creation of a new market
     for "plug-and-play" network attached storage devices, and access to
     Quantum's greater capital and management resources would allow Meridian
     to penetrate the developing market for its products more quickly.

  .  the integration of highly complementary technical resources and
     personnel would enable the combined company to leverage marketing,
     product development, distribution and support efforts, and

  .  the combination with Quantum would create a combined company with
     significantly greater resources, a more diversified product line and
     greater financial and marketing resources than those of Meridian alone,
     and

                                       1
<PAGE>

     would enhance the competitive position of the combined company.

  The Meridian board also considered the uncertainty that it believed existed
concerning Meridian's ability to successfully execute its network attached
storage device strategy as an independent company, and concluded that a
combination with Quantum would reduce its exposure to these risks. In
particular, the Meridian board believed that customer acceptance was a major
hurdle to the success of Meridian's business plan, and recognized that a
combination with Quantum would potentially allow Meridian to roll out new
products and line extensions over a shorter time frame. The Meridian board
recognized that Meridian would have needed to raise substantial additional
funds during 2000 in order for Meridian to continue its required level of
marketing activities, and that any such financing could potentially be
substantially dilutive to the holders of Meridian common stock. The Meridian
board also considered the probable adverse impact on Meridian's prospects as an
independent company in light of the expressed intention by some of Meridian's
larger competitors, including Quantum, to enter the network attached storage
business. Against these considerations the Meridian board weighed, among other
things, the fact that the exchange ratio offered a premium to Meridian
stockholders and, because the consideration was stock in the continuing
enterprise combining Meridian and Quantum, that Meridian's stockholders would
have the opportunity to benefit, on a tax deferred basis, from any growth to be
achieved by such combination, and participation in the execution of Quantum's
strategy to build an integrated storage systems enterprise.

  To review the background and reasons for the merger in greater detail, as
well as the risks of the merger, see "Approval of the Merger and Related
Transactions--Background of the Merger," "--Quantum's Reasons for the Merger"
and "--Meridian's Reasons for the Merger" beginning on page 27 and "Risk
Factors--Risks Relating to the Merger" beginning on page 12.

                          Opinion of Financial Advisor

  In deciding to approve the merger, Meridian's board of directors considered,
among the various factors described below in "Approval of the Merger and
Related Transactions--Meridian's Reasons for the Merger" beginning on page 31,
the opinion of its financial advisor, Donaldson, Lufkin & Jenrette Securities
Corporation, as to the fairness from a financial point of view to Meridian
stockholders of the consideration to be received by the stockholders pursuant
to the terms of the merger agreement. More information on DLJ's opinion is
provided in "Approval of the Merger and Related Transactions--Opinion of
Financial Advisor to Meridian" beginning on page 31. This opinion is attached
as Appendix B to this document. We encourage you to read this opinion carefully
and in its entirety.

                                 Vote Required

  At the close of business on the record date, 8,599,780 shares of Meridian
common stock were outstanding and entitled to vote at the Meridian special
meeting. A majority of the outstanding shares of Meridian common stock entitled
to vote at the Meridian special meeting must vote to approve and adopt the
merger agreement, approve the merger, and ratify the 1997 reincorporation.

               Share Ownership of Management and Certain Holders

  As of the record date, the directors and executive officers of Meridian, as a
group, beneficially owned approximately 531,626 shares of Meridian common stock
(including options exercisable within 60 days of August 4, 1999). An additional
145,878 shares of Meridian common stock were beneficially owned by entities
that received shares from such directors and executive officers after the date
of the merger agreement. These directors and executive officers of Meridian and
such transferees, who together beneficially hold approximately 7.5% of the
Meridian common stock outstanding as of the record date, have entered into
voting agreements with Quantum. These stockholders have agreed to vote in favor
of the proposal and have granted Quantum an irrevocable proxy to vote their
shares of Meridian common stock in favor of the proposal. The affirmative vote
of the shares of the Meridian common stock held by these stockholders will not
be sufficient to approve and adopt the merger agreement or to approve the
merger. For more information on these agreements, see "Approval of the Merger
and Related Transactions--Meridian Voting Agreements" beginning on page 36.

                                       2
<PAGE>


  As of June 4, 1999, the directors and executive officers of Quantum, as a
group, beneficially owned approximately 2,567,737 shares of Quantum common
stock. Upon stockholder approval of Quantum's tracking stock proposal on July
23, 1999 and the filing of Quantum's restated certificate of incorporation on
August 3, 1999, these shares were converted into 2,567,737 shares of Quantum
DLT & Storage Systems Group common stock and 1,283,868 shares of Hard Disk
Drive Group common stock.

                   Interests of Certain Persons in the Merger

  Meridian's stockholders should note that certain members of Meridian's
management and the Meridian board of directors have interests in the merger as
employees and/or directors that are different from, or in addition to, your
interest as a stockholder. If the merger is completed, certain indemnification
arrangements for persons serving as directors and officers of Meridian at the
time of the merger will be continued for at least six years after the merger is
consummated. The combined company will maintain a policy of directors' and
officers' liability insurance for the benefit of those persons for three years
after the merger. Gianluca Rattazzi will have an employment agreement with
Quantum that provides him with certain employment and severance benefits.
Meridian's severance plan also provides for certain benefits to be provided in
the event of a merger. Mr. Rattazzi will have the right to receive one-year's
salary at the closing of the merger pursuant to Meridian's severance plan. In
addition, pursuant to Meridian's severance plan, upon the closing of the
merger, Charlie Bass will vest in all of his unvested options and Mr. Rattazzi
will vest in 50% of his unvested options, with the remaining 50% to vest in six
equal monthly installments beginning on the seven month anniversary of the
closing of the merger. Monthly installment vesting of the remaining 50% of the
shares covered by such unvested options ceases upon termination of Rattazzi's
continuous service with Quantum pursuant to the employment agreement. Other
benefits are to be provided to Mr. Rattazzi and other employees of Meridian if
they are terminated within one year of the merger. For more information, see
"Approval of the Merger and Related Transactions--Interests of Certain Persons
in the Merger" beginning on page 35.

                            Conditions to the Merger

  Quantum will complete the merger only if a number of conditions are either
satisfied or waived by Quantum, some of which include:

                                       3
<PAGE>

     related to Meridian's failure to obtain the requisite stockholder
     approval prior to reincorporating in Delaware in 1997, and there is no
     reasonable expectation of there occurring an adverse effect or liability
     related thereto

  Meridian will complete the merger only if a number of conditions are
satisfied or waived by Meridian, some of which include:

  .  The representations and warranties of Quantum made in the merger
     agreement, subject to certain materiality limitations, are accurate

  .  Quantum performs certain covenants and obligations contained in the

     listing on Nasdaq or the New York Stock Exchange

  .  There are no restraining orders, injunctions and other orders preventing
     the consummation of the merger or other certain litigation or
     administrative actions or proceedings

  For more information on the conditions to the merger, see "The Merger
Agreement--Conditions to the Merger" beginning on page 44.

                      Termination of the Merger Agreement

  The board of directors of both companies can jointly agree to terminate the
merger agreement at any time without completing the merger. Either company can
terminate the merger agreement if:

  .  we do not complete the merger by December 31, 1999;

  .  a governmental authority or other legal action permanently prohibits the
     merger;

  .  the Meridian stockholders do not approve the merger;

  .  the Meridian stockholders do not ratify the 1997 reincorporation; or

  .  the other party's representations and warranties shall be or have become
     materially inaccurate or the other party breaches or materially fails to
     comply with its obligations under the merger agreement, resulting in the
     inability to satisfy a condition to the completion of the merger.

  In addition, Quantum can terminate the merger agreement if certain triggering
events, as defined in the merger agreement, occur at any time prior to the
adoption and approval of the merger agreement and approval of the merger by the
Meridian stockholders. For more information on the circumstances under which
the merger can be terminated, see "The Merger Agreement--Termination" beginning
on page 53.

                         Expenses and Termination Fees

  We have agreed that we will each pay our own fees and expenses in connection
with the merger, whether or not the merger is consummated, except that we will
share equally all fees and expenses, other than attorneys' fees, in connection
with the filing, printing and mailing of this document and the registration
statement of which this document is a part. Meridian has agreed that if the
merger agreement is terminated under certain circumstances, it will pay to
Quantum a non-refundable fee equal to $4,550,000. For more information, see
"The Merger Agreement--Expenses and Termination Fees" beginning on page 55.

                                No Solicitation

  Under the terms of the merger agreement, Meridian has agreed that it will not
engage in certain activities relating to, or which could result in, an
acquisition proposal from a third party. For more

                                       4

information, see "The Merger Agreement--Covenants--Non-Solicitation" beginning
on page 51.

                   Ownership of Quantum Following the Merger

  Based upon the number of shares of Meridian common stock and Quantum DLT &
Storage Systems group common stock and Hard Disk Drive group common stock
issued and outstanding on the record date, which excludes outstanding options
and other rights to purchase common stock, if the Meridian special meeting were
to have occurred on August 4, 1999, when the exchange ratio would have been
 .447, an aggregate of approximately 3,844,101 shares of Quantum DLT & Storage
Systems group common stock and 1,922,050 shares of Hard Disk Drive group common
stock would have been issued in connection with the merger, representing
approximately 2.3% of the total number of shares of DLT & Storage Systems group
common stock and 2.3% of the total number of shares of Hard Disk Drive group
common stock that would be issued and outstanding after the merger. The actual
exchange ratio in the merger may be different because the average closing
prices for the DLT & Storage Systems group and Hard Disk Drive group common
stock fluctuates continuously. If the Quantum combined average stock price at
the time of the Meridian special meeting exceeds $20.48, fewer shares of DLT &
Storage Systems group common stock and Hard Disk Drive group common stock will
be issued in the merger; if the Quantum combined average stock price at the
time of the Meridian special meeting is less than $14.00, more shares of DLT &
Storage Systems group common stock and Hard Disk Drive group common stock will
be issued in the merger.

  Based on the number of outstanding options to purchase Meridian common stock
as of the record date and the exchange ratio that would have been in effect if
the Meridian special meeting had been held on August 4, 1999, the total number
of outstanding options to purchase Meridian common stock would have become
rights to purchase an aggregate of 892,521 shares of Quantum DLT & Storage
Systems group common stock and 446,260 shares of Hard Disk Drive group common
stock in connection with the merger.

                                  Tax Matters

  We have structured the merger with the intent that the merger will be a tax-
free reorganization for federal income tax purposes. It is a condition to
closing that Quantum and Meridian receive opinions from their respective
counsel that the merger should constitute a tax-free reorganization.

  The exchange of Meridian common stock for DLT & Storage Systems group and
Hard Disk Drive group common stock in the merger should be tax-free to Quantum
and the Meridian stockholders. You should not recognize gain or loss on the
exchange of your Meridian common stock for DLT & Storage Systems group and Hard
Disk Drive group common stock, except that you may be taxed on cash received
for a fractional share. In addition, your aggregate tax basis in the DLT &
Storage Systems group and Hard Disk Drive group common stock that you receive
will equal the aggregate tax basis in your Meridian common stock (reduced by
any tax basis allocable to fractional shares exchanged for cash). The aggregate
tax basis of the DLT & Storage Systems group and Hard Disk Drive group common
stock received by you will be allocated between the DLT & Storage Systems group
and Hard Disk Drive group common stock in proportion to the fair market value
of the DLT & Storage Systems group and Hard Disk Drive group common stock at
the time of the merger. The fact that DLT & Storage Systems group and Hard Disk
Drive group common stock is being issued as consideration in the merger will
result in uncertainties in the tax treatment of the merger to Quantum and the
Meridian stockholders. For more information, see the sections entitled "Risk
Factors Relating to the Merger--There is a Lack of Certainty that the Merger
will be Tax-Free" beginning on page 14 and "--Recent Clinton Administration
Proposal Could Result in Taxation of Issuance of Tracking Stock" beginning on
page 20.

  Tax matters can be complicated, and the tax consequences of the merger to you
will depend on the facts of your own situation. You should consult your own tax
advisors to fully understand the tax consequences of the merger to you.

                        Anticipated Accounting Treatment

  We expect that the merger will be accounted for as a purchase. Following the
merger, the combined company will report on the basis of Quantum's historical
financial statements and the fiscal year end will be March 31. For more
information, see

                                       5
<PAGE>

"Approval of the Merger and Related Transactions--Anticipated Accounting
Treatment" beginning on page 39.

                              Regulatory Approvals

  Quantum and Meridian are not aware of any governmental or regulatory
requirements relating to the consummation of the merger, other than compliance
with applicable federal and state securities laws and the Hart-Scott-Rodino
Antitrust Improvements Act. On May 21, 1999, Quantum and Meridian filed a
notification with the Federal Trade Commission and the Antitrust Division of
the Department of Justice under the HSR Act. On June 7, 1999 we received a
notice of early termination of the waiting period from the FTC. For more
information, see "Approval of the Merger and Related Transactions--Regulatory
Matters" beginning on page 40.

               Restrictions on the Ability to Sell Quantum Stock

  All shares of Quantum stock received by Meridian stockholders in connection
with the merger will be freely transferable unless the holder is considered an
affiliate of either of us under the Securities Act. For a more complete
description of transfer restrictions applicable to our affiliates see the
section entitled "Approval of the Merger and Related Transactions--Resale of
Quantum Common Stock" on page 40.

                Forward-Looking Statements May Prove Inaccurate

  We have each made forward-looking statements in this document that are
subject to risks and uncertainties. Forward-looking statements include the
information concerning possible or assumed future results of operations of
Quantum, Meridian or the combined company. Also, when we use such words as
"believes," "expects," "anticipates" or similar expressions, we are making
forward-looking statements. You should note that the merger and an investment
in securities of Quantum involve certain risks and uncertainties that could
affect the future financial results of Quantum. Some of these risks include:
risks related to the integration of Quantum and Meridian, risks associated with
a fixed exchange ratio, risks relating to the respective businesses of Quantum
and Meridian and other risks and uncertainties discussed under "Risk Factors"
and elsewhere in this document and in the documents Meridian incorporated by
reference. For more information on these risks, see "Risk Factors" beginning on
page 12.

(1) The equivalent Meridian per share price represents 48.9% of the price of
    one share of Quantum common stock. 0.489 is the exchange ratio that would
    have been used if the Meridian special meeting had taken place on May 10,
    1999.

(2) The equivalent Meridian per share price represents 44.7% of the price of
    one share of DLT & Storage Systems group common stock plus 44.7% of half of
    the price of one share of Hard Disk Drive group common stock. .447 is the
    exchange ratio that would have been used if the Meridian special meeting
    had taken place on August 4, 1999, when the five day average Quantum stock
    price was $22.37. The actual exchange ratio may be different than this
    fraction because the average closing price for the DLT & Storage Systems
    group and Hard Disk Drive group common stock, which began trading on August
    4, 1999, fluctuates continuously. The actual prices of Quantum or Meridian
    common stock prior to or at the time the merger is consummated cannot be

     THE DLT & STORAGE SYSTEMS GROUP SUMMARY SELECTED FINANCIAL INFORMATION
   This summary of selected financial information of the DLT & Storage Systems
group for fiscal years 1995 to 1999 should be read along with the DLT & Storage
Systems group's audited combined financial statements contained in this proxy
statement. The summarized selected financial information, other than the
statement of operations data for fiscal years 1995 and 1996 and the balance
sheet data at March 31, 1995, 1996 and 1997, was taken from these financial
statements.

   A number of items affect the comparability of this information.

 . In October 1994, the DLT & Storage Systems group acquired the DLTtape drive
   and DLTtape media cartridge business from Digital Equipment Corporation,
   and formed what is now the DLT & Storage Systems group. The results of
   operations for this business are not included in the DLT & Storage Systems
   group's financial statements for periods prior to the acquisition.

 . Prior to fiscal year 1999, almost all DLTtape media cartridges were sold
   directly by the DLT & Storage Systems group. However, during fiscal year
   1999, increased DLTtape media availability allowed licensed third party
   DLTtape media cartridge manufacturers to sell DLTtape media cartridges for
   which the DLT & Storage Systems group receives royalties. Royalty receipts
   by the DLT & Storage Systems group are reported as royalty revenue, which
   is significantly lower than the equivalent DLTtape media cartridge product
   revenue for the DLT & Storage Systems group. However, this royalty model
   has generated income from operations comparable to that generated by
   DLTtape media cartridge sales made directly by the DLT & Storage Systems
   group.

 . During fiscal year 1997 and the first quarter of fiscal year 1998, the DLT
   & Storage Systems group's supply of DLTtape drives was not sufficient to
   meet demand. As a result, in the first half of fiscal year 1998 a few large
   customers began building up larger inventories of DLTtape drives than were
   required for their normal operations. As the DLT & Storage Systems group's
   manufacturing capacity increased and the DLT & Storage Systems group was
   able to meet customer demand for DLTtape drives, these customers reduced
   their orders to lower inventories to more typical levels. These actions
   resulted in reduced sales of DLTtape drives beginning in the third quarter
   of fiscal year 1998 and more significantly in the fourth quarter of fiscal
   year 1998 and the first quarter of fiscal year 1999.

   On July 23, 1999, Quantum's stockholders approved the issuance of DLT &
Storage Systems group stock and Hard Disk Drive group stock in exchange for the
then existing Quantum common stock. Accordingly, the earnings per share for the
periods presented below reflect the earnings for each DLT & Storage Systems
group share resulting from the recapitalization of Quantum in accordance with
the tracking stock proposal.

        THE HARD DISK DRIVE GROUP SUMMARY SELECTED FINANCIAL INFORMATION
   This summary of selected financial information of the Hard Disk Drive group
for fiscal years 1995 to 1999 should be read along with the Hard Disk Drive
group's audited combined financial statements contained in this proxy
statement. The summarized selected financial information, other than the
statement of operations data for fiscal years 1995 and 1996 and the balance
sheet data at March 31, 1995, 1996 and 1997, was taken from these financial
statements.

   A number of items affect the comparability of this information:

 . Through May 1997, the Hard Disk Drive group combined the results of a
   recording heads business acquired from Digital Equipment in October 1994.
   These operations generated operating losses of $67 million, $70 million,
   $110 million and $9 million in fiscal years 1995 through 1998. In May 1997,
   Quantum sold a 51% interest in these operations to Matsushita-Kotobuki.
   Subsequent losses of this joint venture using the equity method of
   accounting were $66 million in fiscal year 1998 and $41 million (unaudited)
   in the first half of fiscal year 1999. In October 1998, Quantum and
   Matsushita-Kotobuki agreed to dissolve the joint venture, and, as a result,
   the Hard Disk Drive group recorded an additional $101 million loss
   (unaudited) from the investment in the third quarter of fiscal year 1999.

 . The results of operations for fiscal year 1998 include the effect of a $103
   million special charge (unaudited), primarily for inventory write-offs and
   losses on purchase commitments, related to the Hard Disk Drive group's
   high-end hard disk drive products.

   The Hard Disk Drive group currently has two primary product lines; desktop
hard disk drives and high-end hard disk drives. The Hard Disk Drive group has
two separate business units that support these two product lines. The Hard Disk
Drive group's recording heads operation was transferred to Matsushita-Kotobuki
and used in the manufacture of hard disk drives for the Hard Disk Drive group.
The value at which the recording heads were transferred was recorded as an
offset to cost of sales.

   On July 23, 1999, Quantum's stockholders approved the issuance of DLT &
Storage Systems group stock and Hard Disk Drive group stock in exchange for the
then existing Quantum common stock. Accordingly, the earnings per share for the
periods presented below reflect the earnings (loss) for each Hard Disk Drive
group share resulting from the recapitalization of Quantum in accordance with
the tracking stock proposal.

(1) On a preliminary basis, Quantum estimates goodwill and other intangibles of
    approximately $60 million will result from the Merger, which will result in
    annual amortization expense of approximately $8 million. Quantum expects to
    recognize a charge of approximately $10 million upon the closing of the
    Merger for acquired in-process research and development. The pro forma
    combined diluted loss per share figures do not reflect the charge for
    acquired in-process research and development, as the charge is non-
    recurring.
(2) Historical book value per share is computed by dividing stockholders'
    equity by the number of shares of Common Stock outstanding at March 31,
    1999 (Quantum DLT & Storage Systems and Hard Disk Drive groups) and
    December 31, 1998 (Meridian). The pro forma combined book value for Quantum
    is computed by dividing the pro forma combined stockholders' equity by the
    pro forma number of shares of Quantum Common Stock outstanding at March 31,
    1999.
(3) The Meridian equivalent pro forma combined per share amounts are calculated
    by adding the DLT & Storage Systems group combined pro forma per share
    amounts multiplied by the assumed exchange ratio of 0.489 per share and the
    Hard Disk Drive group combined pro forma per share amounts multiplied by
    one half of the assumed exchange ratio (or 0.2445 per share).
(4) The above pro forma combined per share amounts do not reflect the effect of
    shares that Quantum repurchased to offset the dilution caused by the
    issuance of its shares in connection with the acquisition of Meridian. If
    the number of shares of DLT & Storage Systems group and Hard Disk Drive
    group common stock issued to Meridian stockholders were simultaneously
    repurchased in the open market through Quantum's previously announced share
    buyback program, the Quantum DLT & Storage Systems group and Hard Disk
    Drive group and Meridian equivalent pro forma combined diluted income
    (loss) per share amounts would be $0.63, $(1.90) and $(0.17), respectively
    for the year ended March 31, 1999, and the Quantum DLT & Storage Systems
    group and Hard Disk Drive group and Meridian equivalent pro forma combined
    book value per share amounts would be $3.90, $9.52 and $4.24, respectively
    at March 31, 1999.

                                  RISK FACTORS

  This proxy statement/prospectus contains forward-looking statements that
involve known and unknown risks and uncertainties. The actual results of the
combined company may differ materially from those anticipated in these forward-
looking statements. You should carefully consider the risks described below,
elsewhere in this document, and in the documents incorporated herein by
reference in making an investment decision. Keep in mind that the risks
described below are not the only risks facing Quantum, Meridian or the combined
company.

                          Risks Relating to the Merger

Integrating Quantum and Meridian involves risks that may negatively impact the
combined company.

  Integrating Quantum and Meridian will be a complex, time-consuming and
expensive process. Before the merger, Quantum and Meridian operated
independently, each with its own business, business culture, clients, employees
and systems. After the merger, Quantum and Meridian must operate as a combined
organization utilizing common (1) information and communication systems, (2)
operating procedures, (3) financial controls and (4) human resource practices,
including benefit, training and professional development programs. There may be
substantial difficulties, costs and delays involved in integrating Quantum and
Meridian. These may include:

  .  Distracting management from the business of the combined company

  .  Potential incompatibility of corporate cultures

  .  Potential inability to coordinate research and development efforts
     successfully

  .  Costs and delays in implementing common systems and procedures

  Any one or all of these factors may cause increased operating costs, lower
than anticipated financial performance or the loss of clients and employees.
Many of these factors are also outside the control of either company. The
failure to integrate Quantum and Meridian would have a material adverse effect
on the business, financial condition and results of operations of the combined
company.

The number of shares of Quantum DLT & Storage Systems group common stock and
Hard Disk Drive group common stock Meridian stockholders receive for their
Meridian common stock and the value of this consideration will depend on the
sum of (1) the average trading price of DLT & Storage Systems group common
stock over five trading days ending two trading days prior to the Meridian
special meeting and (2) the average of one half of the closing price of one
share of Hard Disk Drive group common stock over the same period.

  The fraction of a share of the Quantum DLT & Storage Systems group common
stock that Meridian stockholders receive in exchange for each share of Meridian
common stock in the merger is known as the exchange ratio. The fraction of a
share of the Quantum Hard Disk Drive group common stock that Meridian
stockholders receive in exchange for each share of Meridian common stock is
one-half of the exchange ratio. The exchange ratio will depend on the sum of
(1) the average of the closing sales price of Quantum DLT & Storage Systems
group common stock over the five trading days ending on the second trading day
preceding the Meridian special meeting and (2) the average of one half of the
closing price of one share of Hard Disk Drive group common stock over the same
period. Had the Meridian special meeting been held on August 4, 1999, you would
have received .447 of a share of Quantum DLT & Storage Systems group common
stock and half as many shares (or .2385 of a share) of Hard Disk Drive group
common stock (which would have had an implied combined value of $9.65) for each
share of Meridian common stock you own. However, because the exchange ratio
will fluctuate based on the market price of DLT & Storage Systems group and
Hard Disk Drive group common stock, you may receive less than .447 of a share
of DLT & Storage Systems group common stock and .2385 of a share of Hard Disk
Drive group common stock (and an implied combined value of less than $9.65) in
the merger for each share of Meridian common stock you own.

                                       12
<PAGE>

A fixed exchange ratio is risky because the value of the consideration issued
per share of Meridian common stock will depend on the trading prices of DLT &
Storage Systems group and Hard Disk Drive group common stock.

  Within certain ranges of average closing prices over five trading days, the
exchange ratio is pre-determined or a "fixed exchange ratio." A fixed exchange
ratio means that you will receive a pre-determined number of shares of DLT &
Storage Systems group and Hard Disk Drive group common stock regardless of the
actual five day average. A fixed exchange ratio is risky because, where it
applies, the fixed fractions of DLT & Storage Systems group and Hard Disk Drive
group common shares that you would receive in the merger would have a lower
value if the prices of DLT & Storage Systems group and Hard Disk Drive group
common stock decline. No additional shares are issued within the range of the
fixed exchange ratio, even if the value of shares of DLT & Storage Systems
group and Hard Disk Drive group common stock based upon the five day average
decreases. We call this a lower "implied value." The following example
illustrates this effect:

    If the sum of (1) the average trading price of DLS & Storage Systems
  group common stock over the five trading days ending two trading days prior
  to the Meridian special meeting and (2) the average of one half of the
  closing price of one share of Hard Disk Drive group common stock over the
  same period (the "combined average stock price") is $20.00, you would
  receive 0.489 of a share of Quantum DLT & Storage Systems group common
  stock and half as many shares (or 0.2445 of a share) of Hard Disk Drive
  group stock for each share of Meridian common stock that you own. Those
  combined fractional shares would have an implied value of $20.00 multiplied
  by 0.489, or $9.78 per share. If however, the combined average stock price
  is $14.00 per share, you would still receive 0.489 of a share of Quantum
  DLT & Storage Systems group common stock and half as much (or 0.2445) of a
  share of Hard Disk Drive group common stock for each share of Meridian
  common stock that you own, but the combined fractional shares would have an
  implied value of only $6.85.

A fixed exchange ratio is risky because an increase in the combined average
stock price of DLT & Storage Systems group and Hard Disk Drive group common
stock would result in fewer shares being issued to Meridian stockholders.

  Within certain ranges of combined average stock prices, the exchange ratio
provides for a predetermined implied value or a "fixed price." A fixed price
means that you will receive a fixed dollar value of DLT & Storage Systems group
and Hard Disk Drive group common stock, regardless of the actual combined
average stock price. The number of DLT & Storage Systems group and Hard Disk
Drive group shares that you will receive in the merger will adjust up or down
so that you will receive a predetermined implied value in the merger. A fixed
price is risky because, where it applies, an increase in the combined average
stock price will result in Meridian stockholders receiving fewer shares of DLT
& Storage Systems group and Hard Disk Drive group common stock in the merger.
You would not receive consideration in the merger having a higher implied value
even if the combined average stock price increases. The following examples
illustrate this effect:

  .  If the combined average stock price is $22.00, you will receive 0.455 of
     a share of Quantum DLT & Storage Systems group common stock and half as
     much (or 0.2275) of a share of Hard Disk Drive group common stock for
     each share of Meridian common stock that you own. The combined implied
     value of these fractional shares would be $10.00.

  .  If the combined average stock price is $24.00, you will receive only
     0.417 of a share of Quantum DLT & Storage Systems group common stock and
     half as many shares (or 0.2085 of a share) of Hard Disk Drive group
     common stock for each share of Meridian common stock that you own. The
     combined implied value of these fractional shares would still be $10.00

  The implied value per share of Meridian common stock in the merger can not
exceed $10.00, regardless of changes in the price of DLT & Storage Systems
group and Hard Disk Drive group common stock, and can be as low as $6.85. See
page 42 for a table showing the fraction of a share of DLT & Storage Systems
group and Hard Disk Drive group common stock that would be exchangeable for
each share of Meridian common stock based upon a range of combined average
stock prices.

Quantum common stock has experienced extreme fluctuations in price and volume
which could affect the number and value of shares issued to you.

  In recent years, and particularly in recent months, the stock market and the
trading prices of Quantum common stock have experienced extreme price and
volume fluctuations. The broad market fluctuations have in the past, and may in
the future, adversely affect the market price of Quantum stock. The value of
Quantum stock at the time of the special meeting, completion of the merger, the
date that you receive shares of Quantum stock or the date that you eventually
sell your Quantum shares, may be significantly different than the price of
Quantum stock today. In addition, the exchange ratio is based upon the combined
average five trading day closing price of one share of DLT & Storage Systems
group common stock and half a share of Hard Disk Drive group common stock. The
combined average closing price over five trading days, or implied value, may be
significantly greater than or less than the actual trading prices of DLT &
Storage Systems group and Hard Disk Drive group common stock at the time of the
special meeting, completion of the merger, the date that you receive shares of
Quantum stock or the date you eventually sell your Quantum shares. We encourage
Meridian stockholders to obtain current market quotations for Quantum stock and
Meridian common stock. Neither company may terminate that merger agreement or
elect not to complete the merger solely because of changes in their stock
prices.

Rights of Meridian stockholders will change after the merger.

  Following the merger, Meridian stockholders will become Quantum stockholders.
There are important differences between the rights of Meridian stockholders and
the rights of Quantum stockholders. For a description of these differences, see
"Comparison of Stockholders' Rights."

There is a lack of certainty that the merger will be tax-free.

  It is a condition to the obligation of each of Quantum and Meridian to
complete the merger that such party receive a tax opinion from its counsel that
provides that the merger should be treated for U.S. federal income tax purposes
as a "reorganization" within the meaning of Section 368(a) of the Internal
Revenue Code. There are no Internal Revenue Code provisions, U.S. federal
income tax regulations, court decisions or published Internal Revenue Service
rulings bearing directly on the treatment of tracking stock issued in a merger.
As a result, it is possible that the Internal Revenue Service could take a
position inconsistent with the tax opinions which are not binding on the
Internal Revenue Service or the courts but represent only counsel's best legal
judgment based on current law. If the Internal Revenue Service were to take
such a position and prevail, then:

  .  you would recognize gain or loss in an amount equal to the difference
     between the fair market value on the date of the merger of the tracking
     stocks (the DLT & Storage Systems group common stock and the Hard Disk
     Drive group common stock) that you recieve in the merger and your basis
     in your Meridian common stock;

  .  your basis in the shares of the tracking stocks you receive would equal
     the fair market value of such stocks on the date of the merger;

  .  your holding period in each of the tracking stocks received would begin
     the day after the merger is consummated; and

  .  Quantum could recognize gain for U.S. federal income tax purposes based
     on the fair market value of the tracking stocks issued in the merger.

  For a description of the material federal income tax consequences of the
merger to the Meridian stockholders, see "Approval of the Merger and Related
Transactions--Material Federal Income Tax Consequences" beginning on page 37.

                     Risks Relating to the Combined Company

Risks Relating to the DLT & Storage Systems Group

Competition may increase in the tape drive market as a result of large
competitors introducing tape drive products based on new technology standards

  The DLT & Storage Systems group competes with companies that develop,
manufacture, market and sell tape drive products. The DLT & Storage Systems
group's principal competitors include Exabyte, Hewlett-Packard, Seagate, Sony
and StorageTek. These competitors are aggressively trying to develop new tape
drive technologies that compete more successfully with DLTtape technology.
Hewlett-Packard, IBM and Seagate have formed a consortium to develop new linear
tape drive products. The DLT & Storage Systems group expects products based on
this developing technology standard to target the high-capacity data back-up
market and to compete with the DLT & Storage Systems group's products based on
Super DLTtape technology. Such competition could have a material adverse impact
on the DLT & Storage Systems group's operating results.

The DLT & Storage Systems group's operating results depend on new product
introductions which may not be successful

  To compete effectively, the DLT & Storage Systems group must improve existing
products and introduce new products, such as products based on Super DLTtape
technology and network attached storage appliances. The DLT & Storage Systems
group cannot assure you that:

  .  it will introduce any of these new products in the time frame the DLT &
     Storage Systems group currently forecasts;

  .  it will not experience technical or other difficulties that could
     prevent or delay the introduction of these new products;

  .  its new products will achieve market acceptance;

  .  its new products will be successfully or timely qualified with the DLT &
     Storage Systems group's customers by meeting customer performance and
     quality specifications. A successful and timely customer qualification
     must occur before customers will place large product orders; or

  .  it will achieve high volume production of these new products in a timely
     manner, if at all.

  This risk is magnified because the DLT & Storage Systems group expects
technological changes, customer requirements and increasing competition could
result in declining sales and gross margins on its existing products.

Reliance on a limited number third-party suppliers could result in
significantly increased costs and delays in the event these suppliers
experience shortages or quality problems

  The DLT & Storage Systems group depends on a limited number of suppliers for
components and sub-assemblies, including recording heads, media cartridges and
integrated circuits, all of which are essential to the manufacture of DLTtape
drives and tape libraries. The DLT & Storage Systems group currently purchases
the DLTtape media cartridges it sells primarily from Fuji and Maxell. The DLT &
Storage Systems group cannot assure you that Fuji or Maxell will continue to
supply adequate high quality media cartridges in the future. If component
shortages occur, or if the DLT & Storage Systems group experiences quality
problems with component suppliers, shipments of products could be significantly
delayed and/or costs significantly increased.

  In addition, the DLT & Storage Systems group qualifies only a single source
for many components and sub-assemblies, which magnifies the risk of future
shortages.

                                       15

The DLT & Storage Systems group's sole supplier of tape heads is located in
China and political instability, trade restrictions or currency fluctuations in
China could have an adverse impact on the DLT & Storage Systems group's
operating results.

  The DLT & Storage Systems group's sole supplier of tape heads is located in
China and political instability, trade restrictions, changes in tariff or
freight rates or currency fluctuations in China could result in increased
costs, delays in shipment and could have an adverse impact on the DLT & Storage
Systems group's operating results.

The DLT & Storage Systems group's quarterly operating results could fluctuate
significantly and past quarterly operating results should not be used to
predict future performance

  The DLT & Storage Systems group's quarterly operating results have fluctuated
significantly in the past and could fluctuate significantly in the future.
Quarterly operating results could be adversely affected by:

  .  an inadequate supply of DLTtape media cartridges;

  .  customers canceling, deferring or rescheduling significant orders as a
     result of excess inventory levels or other factors;

  .  declines in network server demand; or

  .  failure to complete shipments in the last month of a quarter during
     which a substantial portion of the DLT & Storage Systems group's
     products are typically shipped.

A majority of sales come from a few customers and these customers have no
minimum or long-term purchase commitments

  The DLT & Storage Systems group's sales are concentrated with a few
customers. Customers are not obligated to purchase any minimum product volume
and the DLT & Storage Systems group's relationships with its customers are
terminable at will. The loss of, or a significant change in demand from, one or
more key customers could materially adversely impact the DLT & Storage Systems
group's operating results.

Unpredictable end-user demand may cause excess or insufficient inventories
which could result in inventory write-downs or losses and an adverse impact on
the DLT & Storage Systems group's customer relationships

  Unpredictable end-user demand, combined with the computer equipment
manufacturer trend toward carrying minimal inventory levels, increases the risk
that the DLT & Storage Systems group will manufacture and custom configure too
much or too little inventory for particular customers. Significant excess
inventory could result in inventory write-downs and losses while inventory
shortages could adversely impact the DLT & Storage Systems group's relationship
with its customers, either of which could adversely impact the DLT & Storage
Systems group's operating results.

The DLT & Storage Systems group does not control licensee pricing or licensee
sales of DLTtape media cartridges and as a result the DLT & Storage Systems
group's royalty revenue may decline

  The DLT & Storage Systems group receives a royalty fee based on sales of
DLTtape media cartridges by Fuji and Maxell. Under the DLT & Storage Systems
group's license agreements with Fuji and Maxell, each of the licensees
determine the pricing and number of units of DLTtape media cartridges sold by
it. As a result, the DLT & Storage Systems group's royalty revenue will vary
depending upon the level of sales and prices set by Fuji and Maxell. In
addition, lower licensee pricing could require the DLT & Storage Systems group
to lower its prices on direct sales of DLTtape media cartridges which would
adversely impact the DLT & Storage Systems group's margins for this product.

                                       16
<PAGE>

Third party infringement claims could result in substantial liability and
significant costs

  From time to time, third parties allege the DLT & Storage Systems group's
infringement of and need for a license under their patented or other
proprietary technology. Adverse resolution of any third party infringement
claim could subject the DLT & Storage Systems group to substantial liabilities
and require it to refrain from manufacturing and selling certain products. In
addition, the costs incurred in intellectual property litigation can be
substantial, regardless of the outcome.

Risks Relating to the Hard Disk Drive Group

The Hard Disk Drive group's operating results depend on new product
introductions which may not be successful

  To compete effectively, the Hard Disk Drive group must frequently introduce
new hard disk drives. The Hard Disk Drive group cannot assure you that:

  .  it will successfully or timely develop or market any new hard disk
     drives in response to technological changes or evolving industry
     standards;

  .  it will not experience technical or other difficulties that could delay
     or prevent the successful development, introduction or marketing of new
     hard disk drives;

  .  it will successfully qualify new hard disk drives, particularly high-end
     disk drives, with the Hard Disk Drive group's customers by meeting
     customer performance and quality specifications. A successful and timely
     customer qualification must occur before customers will place large
     product orders;

  .  it will quickly achieve high volume production of new hard disk drives;
     or

  .  its new products will achieve market acceptance.

  These risks are magnified because the Hard Disk Drive group expects
technological changes, short product life cycles and intense competitive
pressures to result in declining sales and gross margins on its current
generation products.

The Hard Disk Drive group's inability to successfully incorporate giant
magneto-resistive recording heads into its hard disk drives would have an
adverse impact on product sales

  In calendar year 1999, the Hard Disk Drive group expects increasing
industry-wide competition for hard disk drives that incorporate next
generation recording head technology known as giant magneto-resistive
recording heads. IBM has already commenced shipment of hard disk drives which
incorporate giant magneto-resistive recording heads. The Hard Disk Drive group
cannot assure you that it will be able to incorporate giant magneto-resistive
recording heads into its hard disk drives in a timely manner. If the Hard Disk
Drive group is successful in incorporating giant magneto-resistive recording
heads into its hard disk drives, the Hard Disk Drive group cannot assure you
that such drives will achieve market acceptance.

The Hard Disk Drive group's quarterly operating results could fluctuate
significantly and past quarterly operating results should not be used to
predict future performance

  The Hard Disk Drive group's quarterly operating results have fluctuated
significantly in the past and may fluctuate significantly in the future. As a
result, you should not use the Hard Disk Drive group's past quarterly
operating results to predict future performance. Quarterly operating results
could be adversely affected by:

  .  the ability of Matsushita-Kotobuki, the Hard Disk Drive group's
     exclusive manufacturer, to quickly achieve high volume production of the
     Hard Disk Drive group's hard disk drives;

  .  customers canceling, deferring or rescheduling significant orders;

  .  returns by customers of unsold hard disk drives for credit;

                                      17
<PAGE>

  .  decline in PC demand; or

  .  failure to complete shipments in the last month of a quarter during
     which a substantial portion of the Hard Disk Drive group's products are
     typically shipped.

The Hard Disk Drive group's prices and margins are subject to declines due to
unpredictable end-user demand and oversupply of hard disk drives

  End-user demand for the computer systems which contain the Hard Disk Drive
group's hard disk drives has historically been subject to rapid and
unpredictable fluctuations. As a result, the hard disk drive market tends to
experience periods of excess capacity which typically lead to intense price
competition. If intense price competition occurs, the Hard Disk Drive group may
be forced to lower prices sooner and more than expected and transition to new
products sooner than expected. For example, in fiscal year 1999 and the second
half of fiscal year 1998, as a result of excess inventory in the desktop hard
disk drive market, aggressive pricing and corresponding margin reductions
materially adversely impacted the Hard Disk Drive group's operating results.

  The Hard Disk Drive group experienced similar conditions in the high-end hard
disk drive market during most of fiscal years 1998 and 1999.

Growth of the lower priced PC markets is putting downward pressure on the Hard
Disk Drive group's desktop hard disk drive prices and margins

  The recent growth of the lower priced PC market has led to a shift toward
lower priced desktop hard disk drives, and to significantly reduced gross
margins. The Hard Disk Drive group expects the trend toward lower prices and
margins on hard disk drives to continue. If the Hard Disk Drive group is unable
to lower the cost of its desktop hard disk drives accordingly, gross margins
will continue to decrease.

Intense competition in the desktop and high-end hard disk drive market could
adversely impact the Hard Disk Drive group's operating results

  In the desktop hard disk drive market, the Hard Disk Drive group's primary
competitors are Fujitsu, IBM, Maxtor, Samsung, Seagate and Western Digital. The
desktop hard disk drive market is characterized by more competitiveness than
that seen in the computer industry in general. The Hard Disk Drive group's
operating results and competitive position could be negatively impacted by the
introduction of competitive products with higher performance, higher
reliability and/or lower cost than the Hard Disk Drive group's products.

  In the high-end hard disk drive market, the Hard Disk Drive group's primary
competitors are Fujitsu, Hitachi, IBM, Seagate and Western Digital. Currently,
Seagate and IBM have the largest market share for high-end hard disk drives.
Intense technology and pricing competition has led to losses on the Hard Disk
Drive group's high-end hard disk drive products over the past eight quarters.
The Hard Disk Drive group does not anticipate that its high-end hard disk drive
products will return to profitability prior to shipping its next generation
products.

A majority of sales come from a few customers that have no minimum or long-term
purchase commitments

  The Hard Disk Drive group's sales are concentrated with a few customers.
Customers are not obligated to purchase any minimum product volume and the Hard
Disk Drive group's customer relationships are terminable at will. The loss of,
or a significant change in demand from, one or more key the Hard Disk Drive
group customers could have a material adverse impact on the Hard Disk Drive
group's operating results.

Because the Hard Disk Drive group depends on Matsushita-Kotobuki for the
manufacture of all hard disk drives, adverse material developments in this
critical manufacturing relationship would adversely impact the Hard Disk Drive
group's operating results

  The Hard Disk Drive group's relationship with Matsushita-Kotobuki is critical
to the Hard Disk Drive group's operating results and overall business
performance. The Hard Disk Drive group's dependence on Matsushita-Kotobuki
includes the following principal risks:

  .  Quality and Delivery. The Hard Disk Drive group relies on Matsushita-
     Kotobuki to quickly achieve volume production of new hard disk drives at
     a competitive cost, to meet the Hard Disk Drive group's stringent
     quality requirements and to respond quickly to changing product delivery
     schedules. Failure of Matsushita-Kotobuki to satisfy these requirements
     could have a material adverse impact on the Hard Disk Drive group's
     operating results.

  .  Purchase Forecasts. Matsushita-Kotobuki's production schedule is based
     on the Hard Disk Drive group's forecasts of its purchase requirements,
     and the Hard Disk Drive group has limited rights to modify short-term
     purchase orders. The failure of the Hard Disk Drive group to accurately
     forecast its requirements or successfully adjust Matsushita-Kotobuki's
     production schedule could lead to inventory shortages or surpluses.

  .  Pricing. The Hard Disk Drive group negotiates pricing arrangements with
     Matsushita-Kotobuki on a quarterly basis. Any failure to reach
     competitive pricing arrangements would have a material adverse impact on
     the Hard Disk Drive group's operating results.

  .  Capital Commitment. The Hard Disk Drive group's future growth will
     require that Matsushita-Kotobuki continue to devote substantial
     financial resources to property, plant and equipment to support the
     manufacture of the Hard Disk Drive group's products.

  .  Manufacturing Capacity. If Matsushita-Kotobuki is unable or unwilling to
     meet the Hard Disk Drive group's manufacturing requirements, an
     alternative manufacturing source may not be available in the near-term.

  .  Matsushita-Kotobuki depends on a limited number of component and sub-
     assembly suppliers and component shortages and quality problems or
     delays from these suppliers could result in increased costs and reduced
     sales

  Matsushita-Kotobuki depends on a limited number of qualified suppliers for
components and sub-assemblies, including recording heads, media and integrated
circuits, all of which are essential to the manufacture of the Hard Disk Drive
group's hard disk drives. Matsushita-Kotobuki may qualify only a single source
for certain components and sub-assemblies, which can magnify the risk of
component shortages. Component shortages have constrained the Hard Disk Drive
group's sales growth in the past, and the Hard Disk Drive group believes that
it will periodically experience component shortages. If Matsushita-Kotobuki
experiences quality problems with its component suppliers, the Hard Disk Drive
group's hard disk drive shipments could be significantly delayed or costs could
be significantly increased.

Unexpected warranty costs could have a material adverse impact on operating
results

  The Hard Disk Drive group warrants its products against defects for a period
of one to five years. Actual warranty costs could have a material adverse
impact on the Hard Disk Drive group's operating results if the actual unit
failure rate or unit repair costs are greater than those for which the Hard
Disk Drive group established a warranty accrual.

Third party infringement claims could result in substantial liability and
significant costs

  From time to time, third parties allege the Hard Disk Drive group's
infringement of and need for a license under their patented or other
proprietary technology. For example, in August 1998 Quantum was named as one of
several defendants in a patent infringement lawsuit. The plaintiff, Papst
Licensing GmbH, owns at least 24

                                       19
<PAGE>

U.S. patents, which it asserts that the Hard Disk Drive group has infringed.
Adverse resolution of the Papst litigation or any other third party
infringement claim could subject the Hard Disk Drive group to substantial
liabilities and require it to refrain from manufacturing and selling certain
products. The Hard Disk Drive group cannot assure you that licenses to any
technology owned by Papst or any other third party alleging infringement could
be obtained on commercially reasonable terms, or at all. In addition, the costs
of litigation could be substantial, regardless of the outcome.

The Hard Disk Drive group's foreign manufacturing costs could be adversely
impacted by fluctuations in currency exchange rates

  Matsushita-Kotobuki generally purchases manufacturing components at prices
denominated in U.S. dollars. However, significant increases in currency
exchange rates against the U.S. Dollar could increase Matsushita-Kotobuki's
manufacturing costs and could result in higher product prices and/or declining
margins for the Hard Disk Drive group's products.

         Risks Related To The Quantum Tracking Stock Capital Structure

  The following risk factors arise from Quantum's capital structure that has
two separate classes of tracking stock. The word "our" when used in this
section, refers to Quantum.

Recent Clinton administration proposal could result in taxation of issuance of
tracking stock

  A recent proposal by the Clinton Administration would impose a corporate
level tax on the issuance of tracking stock. If the proposal is enacted,
Quantum could be subject to tax on an issuance of either of the tracking stocks
after the date of enactment. Quantum cannot predict, however, whether the
proposal will be enacted by Congress, and, if enacted, whether it will be in
the form proposed by the Clinton Administration.

You will be stockholders of one company and, therefore, financial effects on
one group could adversely affect the other

  Holders of DLT & Storage Systems group stock and Hard Disk Drive group stock
are the stockholders of a single company. The DLT & Storage Systems group and
the Hard Disk Drive group are not separate legal entities. As a result,
stockholders are subject to all of the risks of an investment in Quantum and
all of our businesses, assets and liabilities. The issuance of the DLT &
Storage Systems group stock and the Hard Disk Drive group stock and the
allocation of assets and liabilities and stockholders' equity between the DLT &
Storage Systems group and the Hard Disk Drive group will not result in a
distribution or spin-off to stockholders of any of our assets or liabilities
and will not affect ownership of our assets or responsibility for our
liabilities or those of our subsidiaries. The assets we attribute to one group
could be subject to the liabilities of the other group, whether such
liabilities arise from lawsuits, contracts or indebtedness that we attribute to
the other group. If we are unable to satisfy one group's liabilities out of the
assets we attribute to it, we may be required to satisfy those liabilities with
assets we have attributed to the other group.

  Financial effects from one group that affect our consolidated results of
operations or financial condition could, if significant, affect the results of
operations or financial condition of the other group and the market price of
the tracking stock relating to the other group. In addition, net losses of
either group and dividends and distributions on, or repurchases of, either
class of tracking stock or repurchases of preferred stock at a price per share
greater than par value will reduce the funds we can pay on each class of
tracking stock under Delaware law.

Holders of tracking stock have stockholder rights specific to their group only
in limited circumstances

   Holders of DLT & Storage Systems group stock or Hard Disk Drive group stock
generally do not have stockholder rights specific to their corresponding
groups. Instead, holders have customary stockholder rights relating to Quantum
as a whole. For example, holders of DLT & Storage Systems group stock and Hard
Disk

                                       20
<PAGE>

Drive group stock would vote as a single class to approve a disposition of all
or substantially all of the assets of Quantum. Holders of either tracking
stock only have the following rights with respect to their particular group:

  .  an opportunity to receive dividends declared by our board of directors
     based on the available dividend amount for their group;

  .  requirements for a mandatory dividend, redemption or conversion upon the
     disposition of all or substantially all of the assets of their group;
     and

  .  a right to vote on matters as a separate voting class in the
     circumstances described in "Description of DLT & Storage Systems group
     stock and Hard Disk Drive group stock--Voting Rights."

Limits exist on voting power of tracking stock

 In circumstances where the two classes of tracking stock vote together as a
 single class, Hard Disk Drive group stock may not initially have any
 influence on the outcome of stockholder voting

   We expect that initially the DLT & Storage Systems group stock will have a
substantial majority of the combined voting power of the tracking stocks.
Except in limited circumstances requiring separate class voting, either class
of tracking stock that is entitled to more than the number of votes required
to approve any stockholder action could control the outcome of a vote--even if
the matter involves a divergence or conflict of the interests of the holders
of the DLT & Storage Systems group stock and the Hard Disk Drive group stock.
These matters may include mergers and other extraordinary transactions.

 In circumstances where a separate class vote is required, the class of
 tracking stock with less than majority voting power can block action

  If Delaware law, New York Stock Exchange rules or our board of directors
requires a separate vote on a matter by the holders of either the DLT &
Storage Systems group stock or the Hard Disk Drive group stock, those holders
could prevent approval of the matter--even if the holders of a majority of the
total number of votes cast or entitled to be cast, voting together as a class,
were to vote in favor of it.

 In circumstances where the two classes of tracking stock vote together as a
 single class, holders of only one class of tracking stock can not ensure that
 their voting power will be sufficient to protect their interests

  Since the relative voting power per share of DLT & Storage Systems group
stock and Hard Disk Drive group stock will fluctuate based on the relative
market values of the two classes of tracking stock, the relative voting power
of a class of tracking stock could decrease. As a result, holders of shares of
only one of the two classes of tracking stock cannot ensure that their voting
power will be sufficient to protect their interests where the holders of the
two tracking stocks vote together as a single class.

Stockholders may not have any remedies for breach of fiduciary duties if any
action by directors and officers has a disadvantageous effect on either class
of tracking stock

  Stockholders may not have any remedies if any action or decision of our
directors or officers has a disadvantageous effect on the DLT & Storage
Systems group stock or the Hard Disk Drive group stock compared to the other
class of tracking stock.

  Recent cases in Delaware involving tracking stocks have established that
decisions by directors or officers involving differing treatment of tracking
stocks are judged under the business judgment rule unless self-interest is
shown. The business judgment rule provides that, absent an abuse of
discretion, a director or officer will be deemed to have satisfied his or her
fiduciary duties to our company and our stockholders if that person is
disinterested and acts in accordance with his or her good faith business
judgment in the interests of our

                                      21
<PAGE>

company and our stockholders as a whole. The business judgment rule could
shield a decision by our directors or officers that adversely affects one class
of stock but was believed to benefit our company and stockholders as a whole.
Accordingly, because of the business judgment rule, holders of a tracking stock
who are disadvantaged by an action of our directors or officers may not be able
to successfully make claims alleging breach of fiduciary duty.

Stock ownership could cause directors and officers to favor one group over the
other

  As a result of the implementation of the tracking stock proposal, we expect
that our directors and officers will have stock and option holdings in both the
DLT & Storage Systems group stock and the Hard Disk Drive group stock.
Anticipated differences in the trading values between the DLT & Storage Systems
group stock and the Hard Disk Drive group stock will cause the relative values
of their interests in the two tracking stocks to vary significantly.
Accordingly, it is possible that they could have an incentive to favor one
group over the other because of the relative values of their interests.

Numerous potential conflicts of interest exist between the classes of tracking
stock which may be difficult to resolve by our board or which may be resolved
adversely to one of the classes

 Our board of directors may pay more or less dividends on one group's tracking
 stock than if that group was a separate company

  Subject to the limitations referred to below, our board of directors has the
authority to declare and pay dividends on the DLT & Storage Systems group stock
and the Hard Disk Drive group stock in any amount. Our board of directors
could, in its sole discretion, declare and pay dividends exclusively on the DLT
& Storage Systems group stock, exclusively on the Hard Disk Drive group stock,
or on both, in equal or unequal amounts. The performance of one group may cause
our board of directors to pay more or less dividends on the tracking stock
relating to the other group than if that other group was a stand-alone
corporation. Our board of directors will not be required to consider the amount
of dividends previously declared on each class, the respective voting or
liquidation rights of each class or any other factor. In addition, Delaware law
and our restated certificate of incorporation impose limitations on the amount
of dividends which may be paid on each class of tracking stock.

 Proceeds of mergers or consolidations may be allocated unfavorably

  Because our restated certificate of incorporation does not specify how
consideration to be received in a merger or consolidation involving Quantum
will be allocated between the holders of DLT & Storage Systems group stock and
the holders of Hard Disk Drive group stock, our board of directors will make
that determination. That determination could favor one group's stockholders at
the expense of the other group's stockholders.

 Holders of either class of tracking stock may be adversely affected by a
 conversion of one group's tracking stock

   Our board of directors could, in its sole discretion and without stockholder
approval, determine to convert shares of DLT & Storage Systems group stock into
shares of Hard Disk Drive group stock, or vice versa at any time including when
either or both classes of tracking stock may be considered to be overvalued or
undervalued. Any conversion at a premium would dilute the interests in Quantum
of the holders of the class of tracking stock being issued in the conversion.
Any conversion would also preclude holders of both classes of tracking stock
from retaining their investment in a security that is intended to reflect
separately the performance of the relevant group. It would also give holders of
shares of the class of tracking stock converted a greater or lesser premium
than any premium that might be paid by a third-party buyer of all or
substantially all of the assets of the group whose stock is converted.

                                       22
<PAGE>

 Allocation of corporate opportunities could favor one group over the other

  Our board of directors may be required to allocate corporate opportunities
between the groups. In some cases, our directors could determine that a
corporate opportunity, such as a business that we are acquiring, should be
shared by the groups. These decisions could favor one group at the expense of
the other.

 Groups may compete with each other to the detriment of their businesses

   Our trading stock capital structure does not prevent the groups from
competing with each other. Any competition between the groups could be
detrimental to the businesses of either or both of the groups. Our Chief
Executive Officer or our board of directors permit indirect competition between
the groups based on his or its good faith business judgment that competition is
in the best interests of our company and all of our stockholders as a whole. In
addition, the groups may compete in a business that is not a principal business
of the other group.

Our board of directors may change our management and allocation policies
without stockholder approval to the detriment of one group

  Our board of directors may modify or rescind our policies with respect to the
allocation of corporate overhead, taxes, debt, interest and other matters, or
may adopt additional policies in its sole discretion without stockholder
approval. A decision to modify or rescind these policies, or adopt additional
policies, could have different effects on holders of DLT & Storage Systems
group stock and holders of Hard Disk Drive group stock or could adversely
affect one class of stockholders compared to the other class. For example, our
board of directors could modify the policy regarding competition between the
groups to prohibit indirect competition altogether. That prohibition could
adversely affect the Hard Disk Drive group and beneficially affect the DLT &
Storage Systems group by preventing the Hard Disk Drive group from selling its
products to third party competitors of the DLT & Storage Systems group.
Conversely, that prohibition could adversely affect the DLT & Storage Systems
group and beneficially affect the Hard Disk Drive group by preventing the DLT &
Storage Systems group from buying products from third party competitors of the
Hard Disk Drive group.

Either group may finance the other group on terms unfavorable to one of the
groups

  We anticipate that we will transfer cash and other property between groups to
finance their business activities. Our board of directors has not adopted
specific criteria to determine whether a particular transfer of cash or
property from one group to the other will be accounted for as a reallocation of
"pooled" debt or preferred stock, a short-term or long-term loan or a sale of
assets. These determinations, including the terms of any transactions accounted
for as a loan, could be unfavorable to either group. For example, we cannot
assure you that any terms that we fix for debt will approximate those that
could have been obtained by the borrowing group if it were a stand-alone
corporation.

Holders of one group's tracking stock may receive less consideration upon a
sale of assets than if the group were a separate company

  Our restated certificate of incorporation provides that if we dispose of all
or substantially all of the assets of either group, we must, subject to certain
exceptions,

  . distribute to holders of that group's tracking stock an amount equal to
    the net proceeds of the disposition; or

  . convert the outstanding shares of that group's tracking stock into shares
    of the other group's tracking stock at a 10% premium for the first five
    years following the implementation of the tracking stock proposal and
    without any premium after that five-year period.

  If the group whose assets are disposed were a separate, independent company
and its shares were acquired by another person, certain costs of that
disposition, including corporate level taxes, might not be payable in

                                       23
<PAGE>

connection with that acquisition. As a result, stockholders of the separate,
independent company might receive a greater amount than the net proceeds that
would be received by holders of the group's tracking stock. In addition, we can
not assure you that the net proceeds per share of that group's tracking stock
will be equal to or more than the market value per share of the tracking stock
prior to or after announcement of a disposition.

It might be possible for an acquiror to obtain control of Quantum by purchasing
shares of only one of the tracking stocks

  A potential acquiror could acquire control of Quantum by acquiring shares of
tracking stock having a majority of the voting power of all shares of tracking
stock outstanding. Such a majority could be obtained by acquiring a sufficient
number of shares of both classes of tracking stock or, if one class of tracking
stock has a majority of the voting power, only shares of that class. We expect
that initially the DLT & Storage Systems group stock will have a substantial
majority of the voting power. As a result, initially, it might be possible for
an acquiror to obtain control of Quantum by purchasing only shares of DLT &
Storage Systems group stock.

Decisions by directors and officers that affect market values could adversely
affect voting and conversion rights

  The relative voting power per share of each class of tracking stock and the
number of shares of one class of tracking stock issuable upon the conversion of
the other class of tracking stock will vary depending upon the relative market
values of the DLT & Storage Systems group stock and the Hard Disk Drive group
stock. The market value of either or both classes of tracking stock could be
adversely affected by market reaction to decisions by our board of directors or
our management that investors perceive to affect differently one class of
tracking stock compared to the other. These decisions could involve changes to
our management and allocation policies, transfers of assets between groups,
allocations of corporate opportunities and financing resources between groups
and changes in dividend policies.

Market price of either class of tracking stock may be affected by the number of
market makers

  The market price of the DLT & Storage Systems group stock or the Hard Disk
Drive group stock may be affected by the number of market makers supporting the
DLT & Storage Systems group stock or the Hard Disk Drive group stock.

Provisions governing tracking stock could discourage a change of control and
the payment of a premium for shares

  Our restated stockholder rights plan could prevent stockholders from
profiting from an increase in the market value of their shares as a result of a
change in control of our company by delaying or preventing a change in control.
The existence of two classes of tracking stock could also present complexities
and could pose obstacles, financial and otherwise, to an acquiring person. In
addition, provisions of Delaware law, the restated certificate of incorporation
and the by-laws may also deter hostile takeover attempts.

                          THE MERIDIAN SPECIAL MEETING

Purpose of the Meridian Special Meeting

  The purpose of the Meridian special meeting is to consider and vote upon the
approval and adoption of the merger agreement and approval of the merger. In
addition, stockholders will consider and vote upon the ratification of
Meridian's 1997 reincorporation in Delaware. This ratification is a condition
to the closing of the merger. Holders of Meridian common stock may also
consider and vote upon such other matters as may be properly brought before the
Meridian special meeting or any postponements or adjournments thereof. The
merger will occur only if both proposals are approved or if Quantum decides to
waive ratification of the 1997 reincorporation as a condition to closing. A
vote against the 1997 reincorporation may have the same effect as a vote
against the merger.

  The Meridian board of directors unanimously approved the merger agreement and
the merger, and recommends a vote FOR adoption and approval of the merger
agreement and FOR approval of the merger and FOR the ratification of the 1997
reincorporation.

Proxies

  The Meridian proxy accompanying this proxy statement/prospectus is being
solicited on behalf of the Meridian board of directors for use at the Meridian
special meeting.

Date, Time and Place of Meeting

  The Meridian special meeting will be held at the Holiday Inn of Santa Cruz,
611 Ocean Street, Santa Cruz, CA 95060, on September 9, 1999 at 9:00 a.m. local
time.

Voting Rights and Outstanding Shares

  Only holders of record of Meridian common stock at the close of business on
the record date will be entitled to notice of and to vote at the Meridian
special meeting. At the close of business on the record date there were
8,599,780 shares of Meridian common stock outstanding and entitled to vote.
Except for the stockholders identified herein under "Security Ownership of
Certain Beneficial Owners and Management of Meridian," as of the record date,
to the knowledge of Meridian, no other person beneficially owned more than 5%
of the outstanding Meridian common stock.

  Each holder of record of Meridian common stock on the record date will be
entitled to one vote for each share held on all matters to be voted upon at the
Meridian special meeting.

Solicitation

  This proxy statement/prospectus was mailed to all Meridian stockholders of
record as of the record date and constitutes notice of the Meridian special
meeting in conformity with the requirements of the Delaware General Corporation
Law ("the DGCL").

  Regardless of whether the merger is consummated, each of Quantum and Meridian
will pay its own costs and expenses incurred in connection with the merger
agreement and the transactions contemplated by the merger agreement, except
that fees and expenses (other than attorneys' fees) incurred in connection with
the printing, filing and mailing of the registration statement and this proxy
statement/prospectus and will be shared equally by Quantum and Meridian. See
"The Merger Agreement--Expenses and Termination Fees."

  Subject to the foregoing, the cost of the solicitation of proxies from
holders of Meridian common stock and all related costs will be borne by
Meridian. In addition, Meridian may reimburse brokerage firms and other persons
representing beneficial owners of shares for their expenses in forwarding
solicitation materials to such

                                       25
<PAGE>

beneficial owners. Original solicitation of proxies by mail may be supplemented
by telephone, telegram or personal solicitation by directors, officers or other
regular employees of Meridian. Meridian has retained Corporate Investor
Communications ("CIC") to assist in the solicitations of proxies from brokers,
nominees, institutions and individuals. As compensation for acting as a
solicitor in connection with the merger and the ratification of the 1997
reincorporation, CIC will be paid a fee not to exceed $10,000 and will also be
reimbursed for certain out-of-pocket expenses. No additional compensation will
be paid to directors, officers or other regular employees for such services.

Vote and Quorum Required

  The presence, in person or by properly executed proxy, of the holders of a
majority of the outstanding shares of Meridian common stock entitled to vote at
the Meridian special meeting is necessary to constitute a quorum.

  Approval of each proposal requires approval of a majority of the outstanding
shares of Meridian common stock as of the record date. All votes will be
tabulated by the inspector of election appointed for the meeting, who will
separately tabulate affirmative and negative votes, abstentions and broker non-
votes. Abstentions and broker non-votes will be counted towards the tabulation
of votes cast on the proposal presented to the stockholders and will have the
same effect as negative votes.

  Pursuant to certain voting agreements (each a "Meridian voting agreement" and
collectively, the "Meridian voting agreements"), Charlie Bass, Gianluca
Rattazzi, Erik Miller, Shmuel Shottan, Peter Johnson, Pierluigi Zappacosta,
Mario Rosati and certain entities that have received Meridian stock from such
persons after the date of the merger agreement (each a "Meridian voting
agreement stockholder" and collectively, the "Meridian voting agreement
stockholders"), who collectively beneficially own 677,504 shares of Meridian
common stock as of the record date, which is 7.5% of the shares outstanding,
have agreed that, prior to the expiration date, they will vote their shares of
Meridian common stock in favor of the adoption and approval of the
reorganization agreement and the approval of the merger. The Meridian voting
agreement stockholders have also delivered to Quantum irrevocable proxies with
respect to the matters covered by the Meridian voting agreements. In addition,
subject to certain exceptions, the Meridian voting agreement stockholders have
agreed not to sell, contract to sell, pledge, grant any option to purchase or
otherwise dispose of or transfer any of their shares of Meridian common stock
(or securities convertible into Meridian common stock) held as of the date of
the reorganization agreement or acquired prior to the expiration date unless
and until the other party to the transfer shall have (i) executed a counterpart
of the Meridian voting agreement and the corresponding irrevocable proxy and
(ii) agreed to hold such Meridian securities subject to all of the terms and
provisions of the Meridian voting agreement. See "Approval of the Merger and
Related Transactions--Meridian Voting Agreements" beginning on page 36.

Voting Of Proxies

  The proxy accompanying this proxy statement/prospectus is solicited on behalf
of the Meridian board of directors for use at the meeting. You are requested to
complete, date and sign the accompanying proxy and promptly return it in the
enclosed envelope or otherwise mail it to Meridian. All properly signed proxies
received by Meridian prior to the vote at the meeting that are not revoked will
be voted at the meeting according to the instructions indicated on the proxies
or, if no direction is indicated, to approve the merger and the ratification of
the 1997 reincorporation.

Revocability of Proxies

  Any person giving a proxy pursuant to this solicitation has the power to
revoke it at any time before it is voted. It may be revoked by filing with the
corporate secretary of Meridian at Meridian's principal offices, a written
notice of revocation or a duly executed proxy bearing a later date, or it may
be revoked by attending the meeting and voting in person. Attendance at the
meeting will not, by itself, revoke a proxy.

                                       26

No Appraisal Rights

  Holders of Meridian common stock are not entitled to dissenters' rights or
appraisal rights with respect to the merger or the ratification of the 1997
reincorporation.

  Holders of Meridian common stock should not send any certificates
representing Meridian common stock. Following the effective time of the merger,
holders of Meridian common stock will receive instructions for the surrender
and exchange of their stock certificates.

                                   PROPOSAL 1

                APPROVAL OF THE MERGER AND RELATED TRANSACTIONS

  The following is a brief summary of certain provisions of the Merger
Agreement, which is attached to this proxy statement/prospectus as Appendix A
and is incorporated by reference. You should read the merger agreement for a
more complete description of the merger. If any of the provisions discussed
below conflict with the merger agreement, the merger agreement will control.

Background of the Merger

  For several years, Quantum's corporate strategy has been to expand its
storage business by increasing its technology base and providing a broader
range of value-added storage products. Two key objectives of this strategy have
been to enter the rapidly growing market for network attached storage
appliances in the near term and, longer term, to develop software to support
embedded intelligence in storage devices and systems. Quantum believes that to
be a leader in the network attached storage appliance marketplace, suppliers
will need to (1) have low-cost products and operations, (2) have systems
expertise, including hardware and software design, (3) have a robust
implementation of a small footprint operating system with unique storage
features, (4) provide their customers with ease-of-use and ownership, and (5)
have a strong channel position and trusted brand. Due to Quantum's expectations
that the network attached storage market will become large and price
competitive, Quantum believes that time-to-market and time-to-volume are
critical to achieving market position and leadership. Several established
companies have announced plans to enter the network attached storage market.
However, despite the fact that the network attached storage appliance
functionality is expected to eventually be integrated into storage devices, no
storage company has entered the market yet.

  By February 1999, Quantum determined that it should enter the network
attached storage appliance market by acquisition. Quantum assigned a team of
senior level management personnel to conduct a preliminary investigation of
companies that either had a functional operating system for an network attached
storage appliance or the capability of rapidly developing one and that might be
suitable for an acquisition. At the end of February, 1999, this management team
identified Meridian as a leading candidate for acquisition.

  On February 19, 1999, Tex Schenkkan, Quantum's Vice President and General
Manager Network Storage Business Unit, called Gianluca Rattazzi, Meridian's
President and Chief Executive Officer, to arrange a meeting to discuss various
joint business opportunities.

  On February 22, 1999, Mr. Schenkkan and Maury Domengeaux, Quantum's Vice
President Marketing, met with Mr. Rattazzi and Shmuel Shottan, Meridian's
Senior Vice President, Engineering and Chief Technology Officer at Meridian's
offices. The parties executed a mutual non-disclosure agreement, and discussed
several joint business opportunities, including, on a preliminary basis, the
possibility of a business combination between Meridian and Quantum.

  On February 25, 1999, Mr. Schenkkan telephoned Mr. Rattazzi to determine
Meridian's interest in merging with Quantum. The discussion covered the topics
of the product offerings and business strategy of each company, trends in the
storage industry, market conditions and the potential strategic, operational
and

                                       27

cultural synergies between the two companies. The two agreed that the Quantum
acquisition team would follow up with initial due diligence.

  Beginning on March 1, 1999 and continuing through May 10, 1999,
representatives of Quantum conducted business and financial due diligence on
Meridian with Meridian's cooperation. During this time period, numerous
meetings, interviews and discussions took place among senior level management
personnel of both companies.

  Quantum senior level management prepared an acquisition proposal to be
presented to Quantum's board of directors. On March 26, 1999, that proposal and
supporting information were mailed to the Quantum board of directors to be
considered at a special meeting of the Quantum board on April 1, 1999.

  At the Quantum special board meeting on April 1, 1999, the acquisition
proposal was presented to and discussed by the Quantum board. The Quantum board
considered, among other things, the potential benefits of the proposed merger,
the risks of the merger and the preliminary results of the due diligence
process. After a detailed discussion of the proposal, the board directed
Quantum management to begin negotiations towards a definitive merger agreement
with Meridian.

  On or about April 2, 1999, Quantum engaged the outside law firm of Cooley
Godward LLP and the investment banking firm of Salomon Smith Barney to assist
it in the merger negotiations. On or about April 20, 1999, Meridian engaged the
law firm of Brobeck, Phleger & Harrison LLP to represent it in connection with
the proposed merger with Quantum. On or about April 22, 1999, Meridian engaged
Donaldson, Lufkin & Jenrette Securities Corporation to provide financial
advisory and investment banking services to Meridian in connection with its
evaluation of a business combination transaction.

  Between April 2, 1999 and May 11, 1999, Quantum's management and legal and
financial advisors conducted due diligence with respect to financial, legal and
operational matters of Meridian. During this period, numerous meetings,
interviews and discussions took place among senior level management personnel
of both companies and their representatives.

  On April 21, 1999 the Meridian board held a regularly scheduled meeting at
which a number of matters were discussed, including the status of the
negotiations with Quantum. Also on April 21, 1999, the Quantum board held a
regularly scheduled meeting at which, after further discussion of the proposal
by the board, the board approved the proposal and directed Quantum management
to negotiate and execute a definitive merger agreement with Meridian.

  On April 26, 1999, a draft of the definitive merger agreement was delivered
by Cooley Godward to Brobeck, Phleger & Harrison. On April 28, 1999
representatives of Quantum, Meridian, Cooley Godward and Brobeck, Phleger &
Harrison met at the offices of Brobeck, Phleger & Harrison in Palo Alto,
California to negotiate a definitive merger agreement and related exhibits.
These negotiations continued in a series of meetings and telephonic
conversations between Quantum and Meridian and their respective legal and
financial advisors between April 28, 1999 and May 9, 1999.

  On April 30, 1999 Quantum and Meridian signed a confidentiality, no-shop and
standstill agreement.

  A special meeting of the Meridian board was held on May 1, 1999 at the
offices of DLJ in Menlo Park, California. At that meeting, members of the
Meridian board were updated regarding the status of the continuing negotiations
with Quantum. The Meridian board listened to a presentation by Brobeck, Phleger
& Harrison regarding the terms of the then-current draft of the merger
agreement and other legal matters. DLJ discussed with the Meridian board the
financial terms of the proposed merger. After discussion, the Meridian board
directed Meridian's management and legal and financial advisors to engage in
further discussions with Quantum regarding the proposed merger.

                                       28

  A special telephonic meeting of the Meridian board was held on May 9, 1999.
At that meeting, members of the Meridian board were updated regarding the
status of the continuing negotiations with Quantum. The Meridian board listened
to a presentation by Brobeck, Phleger & Harrison regarding the terms of the
merger agreement and other legal matters. DLJ presented its analysis of the
financial terms of the proposed merger. See "--Opinion of Financial Advisor to
Meridian." DLJ informed the Meridian board that, if requested, and subject to
the finalization of a definitive agreement, it expected to be in a position to
deliver its written opinion as to the fairness from a financial point of view
of the consideration to be received by Meridian's stockholders in the merger.
After extensive discussion, the Meridian board unanimously voted to approve the
merger subject to, among other things, the receipt of DLJ's written fairness
opinion. On May 10, 1999, DLJ delivered its written opinion to the Meridian
board to the effect that, as of such date, based on and subject to the
assumptions, limitations and qualifications set forth in its written opinion,
the consideration to be received by holders of Meridian common stock pursuant
to the merger agreement was fair to such holders from a financial point of
view.

  On May 10, 1999, in the late afternoon, the merger agreement in its
definitive form was executed by Quantum and Meridian.

  On the early morning of May 11, 1999, Quantum and Meridian jointly announced
their agreement to merge.

  On July 23, 1999 Quantum's stockholders approved the tracking stock proposal
whereby the DLT & Storage System group common stock and Hard Disk Drive group
common stock replaced the then existing common stock. These tracking stocks
began separately trading on the NYSE on August 4, 1999.

Quantum's Reasons For the Merger

  The board of directors of Quantum believes that the proposed merger will
afford the complementary strengths of the two individual companies, will
provide the combined company with several benefits, and will enable the
combined company to capture a fair share of the growing market for network
attached storage appliances. Further, Quantum believes that the proposed merger
will give the combined company the technological and market advantages needed
to become a leader in the further development of intelligent storage devices,
systems and solutions that will be demanded in the future.

The potential benefits to the combined company include the following:

  .  A diversified portfolio of products and systems. The combined company
     will offer the broadest array of storage devices and systems of any
     independent company in the industry.

  .  Low cost leadership. Quantum's expertise in hardware integration and
     Meridian's software expertise will enable the combined company to
     produce a product at low cost.

  .  Systems expertise. The combined company will have both hardware and
     software design strength that will enable products with selective,
     unique storage features and a robust operating system capable of working
     with numerous network protocols.

  .  Ease of ownership for customers. The combined company will be able to
     offer customers simplicity in every aspect of ownership: awareness,
     evaluation, purchase, installation, use and service.

  .  Trusted brand and powerful distribution channel programs. The combined
     company can field a product with the well-promoted and respected Quantum
     brand and can take advantage of Quantum's strong relationship with
     original equipment manufacturers and strong channels, including
     distributors, value added retailers and web-based electronic commerce.

  .  Immediate entry into the network attached storage appliance market. With
     the merger, Quantum will accelerate its entry into the network attached
     storage appliance market with an established portfolio of award-winning
     products.


                                       29
<PAGE>

  .  Snap! Server operating system. Quantum believes that the Snap! Server
     operating system, and the team of software experts at Meridian who
     developed it, can accelerate Quantum's development of advanced software
     to support storage devices and systems.

  In addition to the factors set forth above, in the course of its meetings
during March and April, the Quantum board of directors reviewed and considered
a wide variety of information relevant to the merger including: (i) information
concerning Quantum's and Meridian's respective businesses, historical financial
performance and conditions, operations, products, customers, competitive
positions, prospects and management; (ii) Quantum's management's view as to the
financial conditions, results of operations, and business and financial
potential of Meridian and Quantum before and after giving effect to the merger,
based on management's due diligence; (iii) current financial market conditions
and historical trading market prices, volatility and trading information with
respect to Quantum common stock and Meridian common stock; (iv) the
consideration to be paid to the Meridian stockholders in the merger and the
relationship between the market value of comparable merger transactions; (v)
the belief that the terms of the merger agreement, including the parties'
representations, warranties and covenants, and the conditions to their
respective obligations, are reasonable; (vi) reports from management, legal and
financial advisors as to the results of their due diligence investigation of
Meridian; (vii) the potential impact of the merger on customers and employees
of Meridian and Quantum and (viii) the likely reaction to the merger from the
financial markets.

  The Quantum board of directors also considered a number of potentially
negative factors in its deliberations concerning the merger, including (i) the
potential disruption to the business of both companies following announcement
of the merger, including the effects of employee uncertainty, the possibility
that key employees may leave Meridian or Quantum, and the possibility that key
customers may decide to terminate their relationship with the combined company;
(ii) the dilutive effects of the issuance of shares in the merger and the
higher level of expenses that will be borne by the combined company; (iii)
additional potential problems and costs associated with the integration of both
companies into a single enterprise; (iv) the possibility that the merger would
not be consummated; and (v) the other risks described under "Risk Factors"
herein. After due consideration, the Quantum board of directors concluded that
the benefits of the transaction to Quantum and its stockholders outweighed the
risks associated with the foregoing factors.

Meridian's Reasons For the Merger

  The Meridian board has unanimously approved the merger agreement and the
merger, and unanimously recommends that holders of shares of Meridian common
stock vote for the approval and adoption of the merger agreement and the
merger.

  The Meridian board believes that the merger with Quantum will be beneficial
to Meridian stockholders for the following reasons:

  .  Meridian's business plan is centered around the creation of a new market
     for "plug-and-play" network attached storage devices, and access to
     Quantum's greater capital and management resources would allow Meridian
     to penetrate the developing market for its products more quickly,

  .  the integration of highly complementary technical resources and
     personnel would enable the combined company to leverage marketing,
     product development, distribution and support efforts, and

  .  the combination with Quantum would create a combined company with
     significantly greater resources, a more diversified product line and
     greater financial and marketing resources than those of Meridian alone,
     and would enhance the competitive position of the combined company.

  The Meridian board also considered the uncertainty that it believed existed
concerning Meridian's ability to successfully execute its network attached
storage device strategy as an independent company, and concluded that a
combination with Quantum would reduce its exposure to these risks. In
particular, the Meridian board believed that customer acceptance was a major
hurdle to the success of Meridian's business plan, and recognized that a
combination with Quantum would potentially allow Meridian to roll out new
products and

                                       30
<PAGE>

line extensions over a shorter time frame. The Meridian board recognized that
Meridian would have needed to raise substantial additional funds during 2000 in
order for Meridian to continue its required level of marketing activities, and
that any such financing could potentially be substantially dilutive to the
holders of Meridian common stock. The Meridian board also considered the
probable adverse impact on Meridian's prospects as an independent company in
light of the expressed intention by some of Meridian's larger competitors,
including Quantum, to enter the network attached storage business. Against
these considerations the Meridian board weighed, among other things, the fact
that the exchange ratio offered a premium to Meridian stockholders and, because
the consideration was stock in the continuing enterprise combining Meridian and
Quantum, that Meridian's stockholders would have the opportunity to benefit, on
a tax deferred basis, from any growth to be achieved by such combination, and
participation in the execution of Quantum's strategy to build an integrated
storage systems enterprise.

  The Meridian Board also considered, among other matters:

  .  information concerning Quantum's and Meridian's respective businesses,
     prospects, financial performance and condition, operations, technology,
     management and competitive position,

  .  current financial market conditions and historical market prices,
     volatility and trading information with respect to Quantum common stock
     and Meridian common stock,

  .  the consideration to be received by Meridian stockholders in the merger
     and the relationship between the market value of Quantum common stock to
     be issued in exchange for Meridian common stock and Meridian's business,
     prospects, operations and financial condition,

  .  Meridian's prospects as an independent company executing its network
     attached storage business strategy in a highly volatile competitive
     environment,

  .  the potential for other third parties to enter into strategic
     relationships with or to acquire Meridian,

  .  the ability of Meridian, after receiving the advice of counsel that its
     fiduciary duties require it to do so, to consider and negotiate other
     unsolicited, bona fide, superior acquisition proposals and, in such
     event, to terminate the Agreement subject to a payment of a fee to
     Quantum, and

  .  the financial presentations by DLJ, including its opinion, described
     below, to the effect that, subject to the qualifications and limitations
     contained in DLJ's written opinion, as of the date of the opinion, the
     consideration to be received by holders of Meridian common stock in the
     merger was fair from a financial point of view to Meridian's
     stockholders.

  .  Quantum's proposal to create two new classes of common stock to reflect
     separately the performance of its storage systems and hard disk drive
     businesses.

  In view of the variety of factors considered in connection with its
evaluation of the merger, the Meridian board did not find it practicable to and
did not quantify or otherwise assign relative weight to the specific factors
considered in reaching its determination. Individual members of the Meridian
board may have given different weight to different factors.

Opinion of Financial Advisor to Meridian

  Meridian engaged DLJ to act as Meridian's financial advisor in connection
with the proposed Merger and to evaluate the fairness from a financial point of
view to holders of Meridian common stock of the consideration to be received by
such holders, pursuant to the terms of the merger agreement. DLJ delivered to
the Meridian board of directors its written opinion dated May 10, 1999 to the
effect that, as of such date, based on and subject to the assumptions,
limitations and qualifications set forth in such opinion, the consideration to
be received by holders of Meridian common stock pursuant to the Merger
Agreement was fair to such holders from a financial point of view.


                                       31

  The full text of DLJ's opinion is attached hereto as Appendix B. The summary
of DLJ's opinion set forth in this proxy statement/prospectus is qualified in
its entirety by reference to the full text of DLJ's opinion. You are urged to
read DLJ's opinion carefully and in its entirety for the procedures followed,
assumptions made, other matters considered and limits of the review by DLJ in
connection with its opinion.

  DLJ's opinion was prepared for the Meridian board of directors and was
directed only to the fairness from a financial point of view, as of the date
thereof, of the consideration to be received by Meridian stockholders. Quantum
and Meridian determined the exchange ratio in arm's length negotiations. DLJ's
opinion does not address the relative merits of the Merger or any other
business strategies being considered by the Meridian board of directors, nor
does it address the Meridian board of directors' decision to proceed with the
Merger. DLJ's opinion does not constitute a recommendation to any stockholder
as to how such stockholder should vote on the proposed merger.

  Meridian selected DLJ as its financial advisor because it is an
internationally recognized investment banking firm that has substantial
experience providing strategic advisory services. DLJ was not retained as an
advisor or agent to the stockholders of Meridian or any person other than
Meridian. As part of its investment banking business, DLJ is regularly engaged
in the valuation of businesses and securities in connection with mergers,
acquisitions, underwritings, sales and distributions of listed and unlisted
securities, private placements and valuations for corporate and other purposes.

  In arriving at its opinion, DLJ reviewed the draft dated May 5, 1999 of the
merger agreement and reviewed financial and other information that was publicly
available or furnished to DLJ by Meridian including information provided during
discussions with its management. Included in the information provided during
discussions with Meridian management were certain projections of Meridian for
the period beginning January 1, 1999 and ending on December 31, 2002 prepared
by the Meridian management. At Meridian's direction, for the purposes of DLJ's
analysis, DLJ also relied on the financial forecasts for Quantum prepared and
published by the equity research department of DLJ, for the period beginning
April 1, 1999 and ending March 31, 2001, dated as of April 28, 1999. DLJ was
not provided with any internal financial analyses or forecasts of Quantum
prepared by management of Quantum. In addition, DLJ compared certain financial
and securities data of Meridian and Quantum with various other companies whose
securities were traded in public markets, reviewed the historical stock prices
and trading volumes of the Meridian common stock and Quantum common stock,
reviewed prices and premiums paid in certain other business combinations and
conducted such other financial studies, analyses and investigations as DLJ
deemed appropriate for purposes of rendering the DLJ Opinion. DLJ was not
requested to, and did not, solicit the interest of any other party in acquiring
Meridian.

  In rendering its opinion, DLJ relied upon and assumed the accuracy and
completeness of all the financial and other information that was available to
DLJ from public sources, that was provided to DLJ by Meridian and Quantum or
their respective representatives, or that was otherwise reviewed by DLJ. With
respect to the financial analyses and projections supplied to DLJ by Meridian,
DLJ assumed that they were reasonably prepared on the basis reflecting the best
currently available estimates and judgments of the management of Meridian as to
the future operating and financial performance of Meridian. With respect to the
financial forecasts for Quantum prepared and published by the equity research
department of DLJ, DLJ assumed that they did not differ materially from the
best estimates and judgments of the management of Quantum as to the future
operating and financial performance of Quantum as of the date thereof. DLJ did
not assume any responsibility for making an independent evaluation of any
assets or liabilities or for making any independent verification of any of the
information reviewed by DLJ.

  DLJ's opinion is necessarily based on economic, market, financial and other
conditions as they existed on, and on the information made available to DLJ as
of, the date thereof. DLJ's opinion states that, although subsequent
developments may affect its opinion, DLJ does not have any obligation to
update, revise or reaffirm its opinion. DLJ's opinion does not express an
opinion as to the prices at which Quantum common stock or any other security
issued by Quantum, including the DLT & Storage Systems group common stock and
Hard Disk Drive group common stock, will actually trade at any time.

 Summary of Financial Analyses Performed by DLJ

  The following is a summary of the financial analyses presented by DLJ to the
Meridian board of directors on May 10, 1999 in connection with the preparation
of its opinion.

  Common Stock Trading History. DLJ examined the historical closing prices of
Meridian common stock for the period from May 7, 1998 to May 7, 1999. During
this time period, Meridian common stock reached a high of $5.81 per share and a
low of $1.00 per share. This information was presented solely to provide the
Meridian board of directors with background information on the stock prices of
Meridian over the period indicated.

  Comparable Companies Analysis. DLJ analyzed the market values and trading
multiples of selected publicly traded information storage companies. The
comparable companies consisted of:

  .  Artecon Inc.

  .  Auspex Systems Inc.

  .  Boxhill Systems Corp.

  .  Ciprico Inc.

  .  MTI Technology Corp.

  .  Procom Technology Inc.

  .  Storage Computer Corp.

  In examining these comparable companies, DLJ calculated the enterprise value
of each company as a multiple of its respective: (i) LTM revenue, (ii)
projected 1999 revenue and (iii) projected 2000 revenue. The enterprise value
of a company is equal to the value of its fully-diluted common equity plus debt
and the liquidation value of outstanding preferred stock, if any, minus cash
and the value of certain other assets, including minority interests in other
entities, at a discount to the private market value thereof. LTM is defined as
latest twelve months. Projected 1999 and projected 2000 revenue were obtained
from Wall Street research reports where available. DLJ's analysis of the
comparable companies yielded the following: LTM revenue multiples ranging from
0.2x to 1.9x; projected 1999 revenue multiples ranging from 0.2x to 1.4x; and
projected 2000 revenue multiples ranging from 0.2x to 0.4x. Based on this
analysis, DLJ estimated a value per share of Meridian common stock ranging from
$2.27 to $5.34.

  Precedent M&A Transaction Analysis. DLJ reviewed seventeen selected
acquisitions or proposed acquisitions involving companies which DLJ deemed to
be comparable to Meridian (collectively, the "M&A Comparable Transactions"):

  .  ATL Products Inc. (Odetics)/Quantum Corp.

  .  Encore Computer-Storage Prods./Sun Microsystems Inc.

  .  BusLogic Inc./Mylex Corp.

  .  McData Corp./EMC Corp.

  .  Conner Peripherals Inc./Seagate Technology Inc.

  .  Digital Equip-Disk Drive/Quantum Corp.

  .  Stratus Computer/Ascend Communications

  .  Symbios Inc./LSI Logic Corp.

  .  Digital Equipment Corp./Compaq Computer Corp.

  .  Advanced Logic Research Inc./Gateway 2000 Inc.

  .  Maxtor Corp./Hyundai Electronic Industries Co., Inc.

  .  SuperMac Technology/Radius Inc.


                                       33
<PAGE>

  .  Archive Corp./Conner Peripherals Inc.

  .  Amdahl Corp./Fujitsu Ltd.

  .  OpenVision Technologies, Inc./Veritas Software Corp.

  .  Cheyenne Software/Computer Associates Intl.

  .  Epoch Systems/EMC Corp.

  In examining these acquisitions, DLJ calculated the enterprise value of the
acquired company implied by each of these transactions as a multiple of (i) LTM
revenue and (ii) projected revenue for the twelve months following the
transaction announcement (as obtained by DLJ from industry research where
available). DLJ's analyses of the M&A Comparable Transactions yielded the
following: (i) LTM revenue multiples ranging from 0.4x to 9.2x and (ii)
projected revenue multiples ranging from 0.6x to 6.1x. DLJ's analysis of the
M&A Comparable Transactions, excluding the OpenVision and Cheyenne Software
transactions, yielded the following: (i) LTM revenue multiples ranging from
0.4x to 3.7x and (ii) projected revenue multiples ranging from 0.6x to 2.6x.
Based on this analysis, DLJ estimated a value per share of Meridian common
stock ranging from $2.63 to $8.98.

  Premiums Paid Analysis. DLJ determined the premium over the common stock
trading prices for one day and four weeks prior to the announcement date in (i)
the M&A Comparable Transactions, (ii) all software and computer hardware
related merger and acquisition transactions of U.S. public companies ranging
from $50 million to $150 million in size announced since January 1, 1997, and
(iii) all merger and acquisition transactions of U.S. public companies ranging
from $50 million to $150 million in size announced since January 1, 1997.
Premiums for the software and computer transactions and all merger and
acquisition transactions were obtained from Securities Data Company. The median
premiums for the selected transactions over the common stock trading prices for
one day and four weeks prior to the announcement date were (i) 47.6% and 32.6%,
respectively, for the M&A Comparable Transactions, (ii) 28.0% and 43.2%,
respectively, for the software and computer hardware related transactions, and
(iii) 20.7% and 31.2%, respectively, for all transactions. Applying the above
premiums to the closing price of Meridian common stock on May 7, 1999, DLJ
estimated a value per share of Meridian common stock ranging from $4.07 to
$4.98.

  Discounted Cash Flow Analysis. DLJ performed a DCF analysis of Meridian on
the projected free cash flows of Meridian and on the projected free cash flows
of Meridian using existing net operating losses of approximately $11.7 million
and tax credit carryforwards of approximately $2.4 million, in each case for
the fiscal years ended December 31, 1999 through 2002, using projections and
assumptions provided by the management of Meridian. DCF is defined as
discounted cash flow. The DCFs for Meridian were estimated using discount rates
ranging from 25% to 40%, based on estimates of and judgments related to the
weighted average costs of capital of Meridian, and terminal multiples of
estimated earnings before interest and taxes for Meridian's fiscal year ending
December 31, 2002 ranging from 6.0x to 8.0x. Based on this analysis, DLJ
estimated a value per share of Meridian common stock ranging from $3.26 to
$8.36.

  No company or transaction used in the analyses is directly comparable to
Meridian or the contemplated transaction. In addition, mathematical analysis
such as determining the mean or median is not in itself a meaningful method of
using selected company or transaction data. The analyses performed by DLJ are
not necessarily indicative of actual values or future results, which may be
significantly more or less favorable than suggested by such analyses.

  Pro Forma Merger Analysis. DLJ analyzed certain pro forma effects resulting
from the Merger. DLJ analyzed the pro forma effect of the Merger on earnings
per share for Quantum, assuming no cost savings or incremental revenue benefits
from the combination. The analysis indicated that the pro forma earnings per
share of Quantum in the fiscal years ending December 31, 2000 and 2001 would be
6.8% and 4.3% lower, respectively, than comparable projections for such years
for Quantum as a stand-alone company during the same period. The results of the
pro forma combination analysis are based upon (i) the projected financial

                                       34
<PAGE>

information prepared and published by the equity research department of DLJ
dated as of April 28, 1999, in the case of Quantum and (ii) the assumptions and
projections supplied by the management of Meridian, in the case of Meridian,
and are not necessarily indicative of future operating results or financial
position.

  The summary set forth above does not purport to be a complete description of
the analyses performed by DLJ but describes, in summary form, the material
elements of the presentation made by DLJ to the Meridian board of directors on
May 10, 1999. The preparation of a fairness opinion involves various
determinations as to the most appropriate and relevant methods of financial
analysis and the application of these methods to the particular circumstances
and, therefore, such an opinion is not readily susceptible to summary
description. Each of the analyses conducted by DLJ was carried out in order to
provide a different perspective on the Merger and to add to the total mix of
information available. DLJ's conclusions also involved significant elements of
judgment and qualitative analysis. DLJ did not form a conclusion as to whether
any individual analysis, considered in isolation, supported or failed to
support an opinion as to fairness from a financial point of view. Rather, in
reaching its conclusion, DLJ considered the results of the analyses in light of
each other and ultimately reached its opinion based on the results of all
analyses undertaken as a whole. DLJ did not place particular reliance or weight
on any individual analysis, but instead concluded that its analyses, taken as a
whole, supported its determination. Accordingly, notwithstanding the separate
factors summarized above, DLJ has indicated to Meridian that it believes that
its analyses must be considered as a whole and that selecting portions of its
analyses and the factors considered by it, without considering all analyses and
factors, could create an incomplete view of the evaluation process underlying
its opinion.

 Engagement Letter

  Pursuant to the terms of an engagement agreement dated April 22, 1999,
Meridian engaged DLJ to provide financial advisory and investment banking
services to Meridian and agreed to pay DLJ (i) an initial retainer fee of
$100,000, payable promptly upon the execution of the Engagement Letter; (ii) a
fee of $350,000 payable upon the delivery by DLJ of the DLJ Opinion
(irrespective of the conclusion reached therein); and (iii) additional cash
compensation in an amount equal to one and a half percent (1.5%) of the
aggregate value of the outstanding common stock of Meridian (treating any
shares issuable upon exercise of options, warrants or other rights of
conversion as outstanding on a net exercise basis), plus the amount of any debt
assumed, acquired, remaining outstanding, retired or defeased or preferred
stock redeemed or remaining outstanding in connection with the merger, payable
upon the consummation of the merger; provided that, except as set forth in the
next sentence, in no event shall such additional cash compensation amount be
less than $1,000,000. Any amounts paid by Meridian pursuant to clauses (i) and
(ii) above shall be deducted from the additional cash compensation paid by
Meridian pursuant to clause (iii) above. In addition, Meridian agreed to
reimburse DLJ, upon request by DLJ from time to time, for all reasonable out-
of-pocket expenses (including the reasonable fees and expenses of counsel)
incurred by DLJ in connection with its engagement thereunder, which will not
exceed $50,000 without the prior approval of Meridian, whether or not the
Merger is consummated, and to indemnify DLJ and certain related persons against
certain liabilities in connection with the engagement, including liabilities
under U.S. federal securities laws. DLJ and Meridian negotiated the terms of
the fee arrangement, and the Meridian board of directors was aware of such
arrangement, including the fact that a significant portion of the aggregate fee
payable to DLJ is contingent upon consummation of the merger.

 Other Relationships

  In the ordinary course of business, DLJ and its affiliates may own or
actively trade the securities of Meridian and Quantum for their own accounts
and for the accounts of their customers and, accordingly, may at any time hold
a long or short position in Meridian or Quantum securities.

Interests of Certain Persons in the Merger

  Certain members of Meridian's management and the Meridian board may be deemed
to have certain interests in the merger that are in addition to their interests
as stockholders of Meridian generally. The Meridian board was aware of these
interests and considered them, among other matters, in approving the merger
agreement and the transactions contemplated thereby.

Equity Ownership of Meridian Management.

  As of August 4, 1999, directors and executive officers of Meridian
beneficially owned or had options to acquire within 60 days of that date
531,626 shares of Meridian Common stock for which they will receive the same
consideration as the other Meridian shareholders. As provided in the Merger
Agreement, by virtue of the Merger, each option granted by Meridian to purchase
shares of Meridian common stock which is outstanding and unexercised
immediately prior to the effective time will be assumed by Quantum and
converted into an option to purchase shares of DLT & Storage Systems group and
Hard Disk Drive group common stock in such number and such exercise price as is
described in the Merger Agreement and in the section herein entitled "The
Merger Agreement--Stock Options". As of August 4, 1999, there were outstanding
options to purchase an aggregate of 1,996,692 shares of Meridian common stock
at a weighted average exercise price of $2.27 per share (at exercise prices
ranging from $0.025 to $15.125 per share).

  Indemnification and Insurance. The merger agreement provides that all rights
to indemnification existing in favor of the persons serving as directors and
officers of Meridian as of the date of the merger agreement for acts or
omissions occurring prior to the effective time, as provided in the Meridian
bylaws and in any indemnification agreements between Meridian and such
directors and officers, will survive the merger, and that Quantum will cause
Meridian (the "surviving corporation") to perform its obligations arising
thereunder for at least six years from the effective time. Subject to certain
limitations, Quantum has also agreed to cause the surviving corporation to
maintain in effect for three years after the effective time a policy of
directors' and officers' liability insurance for the benefit of persons serving
as directors and officers of Meridian as of such date. See "The Merger
Agreement--Covenants--Indemnification and Insurance."

  Employment Agreement with Gianluca Rattazzi. At the closing of the merger,
Gianluca Rattazzi will have an employment agreement with Quantum pursuant to
which he will receive salary and benefits commensurate with his position and
will be entitled to acceleration of his options if he is terminated without
cause or resigns with good reason within the first year.

  Meridian Severance Plan. Mr. Rattazzi will have the right to receive one-
year's salary at the closing of the merger pursuant to Meridian's severance
plan. In addition, pursuant to Meridian's severance plan, upon the closing of
the merger, Mr. Bass will vest in all of his unvested options and Mr. Rattazzi
will vest in 50% of his unvested options, with the remaining 50% to vest in six
equal monthly installments beginning on the seven month anniversary of the
closing of the merger. Monthly installment vesting of the remaining 50% of the
shares covered by such unvested options ceases upon termination of Rattazzi's
continuous service with Quantum pursuant to the employment agreement. In
addition, certain other employees of Meridian are participants in the Meridian
severance plan, which provides for the payment of certain separation benefits
to officers and other employees of Meridian in the event of termination, other
than for cause, within one year following a change in control of Meridian. The
merger constitutes a "change of control" under the severance plan. Under the
severance plan, certain officers of Meridian are entitled to receive twenty-
five or fifty percent, depending on the employee, of their annual base
compensation and to vesting in 100% of their unvested options upon termination
within one year of the merger. Benefits will also be provided for the three or
six months, depending on the employee. In addition to actual termination,
certain employees may terminate their employment and be entitled to separation
benefits if at any time during the one year period following merger (i) the
employee's base annual salary is reduced, unless a reduction in base annual
salary is implemented for the majority of the employees of Quantum; (ii) the
employee is required to change the location of his or her job by more than
fifty (50) miles; or (iii) there is a material adverse diminution in the
employee's duties and responsibilities.

Meridian Voting Agreements

  Pursuant to the Meridian voting agreements, the Meridian voting agreement
stockholders, who beneficially own an aggregate of 531,626 outstanding shares
of Meridian common stock (including options exercisable within 60 days of
August 4, 1999). An additional 145,878 shares of Meridian common stock were
beneficially owned by entities that received shares from such directors and
executive officers after the date of the merger agreement. These directors and
executive officers of Meridian and such transferees (representing approximately

                                       36
<PAGE>

7.5% of the shares of Meridian common stock as of May 10, 1999) have agreed
that, prior to the expiration date, they will vote their shares of Meridian
common stock in favor of: (i) approval and adoption of the merger agreement;
(ii) approval of the merger; and (iii) each of the other actions contemplated
by the merger agreement. The Meridian voting agreement stockholders have also
delivered to Quantum irrevocable proxies with respect to the matters covered by
the Meridian voting agreements. In addition, the Meridian voting agreement
stockholders have agreed not to transfer any securities of Meridian owned by
them unless and until the proposed transferee of such Meridian securities shall
have (i) executed a counterpart of the Meridian voting agreement and an
irrevocable proxy and (ii) agreed to hold such Meridian securities subject to
all of the terms and provisions of the Meridian voting agreement. The
affirmative vote of the shares of Meridian common stock subject to the Meridian
voting agreements will not be sufficient to approve and adopt the merger
agreement or to approve the merger. The form of Meridian voting agreement is
attached to this proxy statement/prospectus as Appendix C.

Meridian Affiliate Agreements

  Each member of the Meridian board and certain officers of Meridian who are
"affiliates" of Meridian within the meaning of Rule 145 promulgated under the
Securities Act, executed an affiliate agreement that will be effective as of
the closing of the merger. Pursuant to the Meridian affiliate agreements,
Quantum will be entitled to place appropriate legends on the certificates
evidencing any Quantum common stock to be received by a Meridian affiliate
pursuant to the terms of the merger agreement, and to issue appropriate stop
transfer instructions to the transfer agent for the Quantum common stock,
consistent with the terms of the Meridian affiliate agreement. Pursuant to such
agreements, such directors and officers will have also acknowledged the resale
restrictions imposed by Rule 145 under the Securities Act on shares of Quantum
common stock to be received by them in the merger.

Amendment to Meridian Severance Plan

  In connection with the merger, Meridian is amending its severance plan to
reduce the severance benefits provided to Mr. Rattazzi and to clarify and
narrow the circumstances in which severance benefits will be paid.

Material Federal Income Tax Consequences

  The following discussion describes the material federal income tax
consequences generally applicable to Meridian stockholders. The discussion is
based on current law. Changes in the law could affect the federal income tax
consequences of the merger to Meridian stockholders. This discussion assumes
that Meridian stockholders hold their Meridian common stock as capital assets
within the meaning of Section 1221 of the Internal Revenue Code. We have not
and will not seek a ruling from the IRS in connection with the merger. This
discussion does not address the consequences of the merger under state, local
or foreign law, nor does the discussion address all aspects of federal income
taxation that may be important to a Meridian stockholder in light of his or her
particular circumstances or tax issues that may be significant to Meridian
stockholders subject to special rules, such as:

  .  financial institutions;

  .  insurance companies;

  .  foreign individuals and entities;

  .  tax-exempt entities;

  .  dealers in securities;

  .  persons who are subject to the alternative minimum tax provisions of the
     Internal Revenue Code;

  .  persons who acquired Meridian common stock pursuant to the exercise of
     an employee option (or otherwise as compensation); or

  .  persons who acquired Meridian common stock as part of an integrated
     investment, such as a "hedge" or "straddle," composed of Meridian common
     stock and one or more other positions.

                                       37
<PAGE>

  Accordingly, Meridian stockholders are urged to consult their own tax
advisors as to the specific tax consequences of the merger to them, including
the applicable federal, state, local and foreign tax consequences.

  Meridian's obligation to consummate the merger is conditioned on the receipt
by Meridian of an opinion from Brobeck, Phleger & Harrison, and Quantum's and
Defiant Acquisition Sub's obligations to consummate the merger are conditioned
on their receipt of an opinion from Cooley Godward, that the merger should
constitute a "reorganization" within the meaning of Section 368(a) of the
Internal Revenue Code. Such conditions will not be waived without a
resolicitation of consent by the stockholders of Meridian. These opinions
neither bind the IRS or the courts nor preclude the IRS or a court from
adopting a contrary position.

  Assuming that the merger qualifies as a reorganization the following federal
income tax consequences will result:

  .  Exchange of Meridian Common Stock for Quantum Tracking Stocks. Except as
     discussed below, no gain or loss will be recognized by a Meridian
     stockholder upon the receipt of DLT & Storage System group stock and
     Hard Disk Drive group stock in the merger. Each Meridian stockholder's
     aggregate tax basis in the DLT & Storage System group stock and Hard
     Disk Drive group stock received in the merger will be the same as the
     aggregate tax basis of the Meridian common stock surrendered in the
     merger (reduced by any tax basis allocable to fractional shares
     exchanged for cash). The aggregate tax basis of the DLT & Storage System
     group stock and Hard Disk Drive group stock received by a Meridian
     stockholder in the merger will be allocated between the DLT & Storage
     System group stock and Hard Disk Drive group stock in proportion to the
     fair market value of the DLT & Storage System group stock and Hard Disk
     Drive group stock at the effective time of the merger. The holding
     period of the DLT & Storage System group stock and Hard Disk Drive group
     stock received by a Meridian stockholder in the merger will include the
     period during which the Meridian common stock surrendered in exchange
     were held; and

  .  Cash Received Instead of Fractional Shares. A Meridian stockholder who
     receives cash in the merger instead of a fractional share interest in
     the DLT & Storage System group stock and Hard Disk Drive group stock
     will be treated as having received the fractional share interest and
     then having sold such interest for the cash received. This sale will
     generally result in the recognition of gain or loss for U.S. federal
     income tax purposes, measured by the difference between the amount of
     cash received and the tax basis of such fractional share interest, which
     gain or loss will be capital gain or loss.

  Stockholders should be aware that the issuance of Quantum's tracking stocks
in the merger will result in uncertainties in the tax treatment of the merger.
There are no Internal Revenue Code provisions, U.S. federal income tax
regulations, court decisions or published IRS rulings bearing directly on the
treatment of tracking stocks. The IRS announced during 1987 that it was
studying the U.S. federal income tax consequences of stock that has certain
voting and liquidation rights in an issuing corporation, but has dividend
rights that are determined by reference to the earnings of a segregated portion
of the issuing corporation's assets, and that it would not issue any advance
rulings regarding such stock. Although the IRS has since withdrawn such stock
from its list of matters under consideration, it has reiterated that it will
not issue advance rulings regarding such stock. Furthermore, a recent proposal
by the Clinton Administration would impose a corporate-level tax on the
issuance of tracking stock. If this proposal is enacted, Quantum could be
subject to tax on an issuance of DLT & Storage Systems group stock and Hard
Disk Drive group stock after the date of enactment. Quantum cannot predict,
however, whether the proposal will be enacted by Congress and, if enacted,
whether it will be in the form proposed by the Clinton Administration.

  In the absence of authorities directly on point, there is a risk that the IRS
could assert that the tracking stocks represent property other than stock of
Quantum and that the merger does not constitute a reorganization. There is no
assurance that the IRS would not prevail in a court of law on this issue. For
more information, see the sections entitled "Risk Factors Relating to the
Merger--There is a Lack of Certainty that the Merger will be Tax-Free" and
"Recent Clinton Administration Proposal Could Result in Taxation of Issuance of
Tracking Stock".

                                       38
<PAGE>

  There are other tax-related issues that you should be aware of such as:

  .  Reporting Requirements. Each Meridian stockholder that receives Quantum
     tracking stocks in the merger will be required to file a statement with
     his or her federal income tax return setting forth his or her basis in
     the Meridian common stock surrendered and the fair market value of the
     Quantum tracking stocks and cash received in the merger, and to retain
     permanent records of these facts relating to the merger.

  .  Backup Withholding. Unless an exemption applies under applicable law and
     regulations, the exchange agent is required to withhold, and will
     withhold, 31% of any cash payments to a Meridian stockholder in the
     merger unless the stockholder provides the appropriate form as described
     below. Each Meridian stockholder should complete and sign the Substitute
     Form W-9 included as part of the letter of transmittal to be sent to
     each Meridian stockholder, so as to provide the information, including
     such stockholder's taxpayer identification number, and certification
     necessary to avoid backup withholding, unless an applicable exemption
     exists and is proved in a manner satisfactory to Quantum and the
     exchange agent.

  .  Consequences of IRS Challenge. A successful IRS challenge to the
     reorganization status of the merger would result in significant tax
     consequences. Meridian stockholders would recognize gain or loss with
     respect to each share of Meridian common stock surrendered in the
     merger. Such gain or loss would be equal to the difference between the
     stockholder's basis in such share and the sum of the fair market value,
     as of the effective time, of the Quantum tracking stocks received in the
     merger and any cash received instead of a fractional share or shares of
     Quantum tracking stocks. In such event, a stockholder's aggregate basis
     in the Quantum tracking stocks so received would generally equal its
     fair market value as of the effective time and the stockholder's holding
     period for such stock would begin the day after the merger is
     consummated. See "Risk Factors Relating to the Merger--There is a Lack
     of Certainty that Merger will be Tax-Free and Recent Clinton
     Administration Proposal Could Result in Taxation of Issuance of Tracking
     Stock."

  Even if the merger qualifies as a reorganization, a recipient of Quantum
tracking stocks would recognize income to the extent that, for example, any
such shares were determined to have been received in exchange for services, to
satisfy obligations or in consideration for anything other than the Meridian
common stock surrendered. Generally, such income is taxable as ordinary income
upon receipt. In addition, to the extent that Meridian stockholders were
treated as receiving, directly or indirectly, consideration other than Quantum
tracking stocks in exchange for such stockholder's Meridian common stock, gain
or loss would have to be recognized.

  The preceding discussion is not meant to be a complete analysis or discussion
of all potential tax effects of the merger. Thus, Meridian stockholders are
urged to consult their own tax advisors as to the specific tax consequences to
them of the merger, including tax return reporting requirements, federal,
state, local and other applicable tax laws and the effect of any proposed
changes in the tax laws.

Anticipated Accounting Treatment

  In the proposed transaction, Quantum will be acquiring all of the outstanding
shares of Meridian stock and the combination will be accounted for under the
purchase method of accounting. The excess of the purchase price over the fair
value of Meridian's specific tangible and identifiable intangible assets and
liabilities will be recorded as goodwill. On a preliminary basis, Quantum
estimates goodwill and other intangibles of approximately $60 million will
result from the merger, which will result in annual amortization expense of
approximately $8 million (assuming an average life of ten years). Quantum
expects to recognize a charge of approximately $10 million upon closing of the
merger for acquired in-process research and development.

Regulatory Matters

  Antitrust. Quantum and Meridian are not aware of any governmental or
regulatory requirements relating to the consummation of the merger other than
compliance with the HSR Act. Under the HSR Act and the rules promulgated
thereunder by the FTC, the merger may not be consummated until notifications
have been given and certain information has been furnished to the FTC and the
Antitrust Division and specified waiting period requirements have been
satisfied or early termination of the waiting period is granted at the request
of Quantum and Meridian. On May 21, 1999, Quantum and Meridian filed
notification and report forms under the HSR Act with the FTC and the Antitrust
Division. On June 7, 1999, we received a notice of early termination of such
waiting period from the FTC.

  Filing with the Secretary of State of the State of Delaware. A Certificate of
Merger must be filed with the Secretary of State of Delaware to consummate the
merger.

Absence of Meridian Appraisal Rights

  Under Section 262 of the DGCL, stockholders who do not vote in favor of or
consent to a merger are not entitled to appraisal rights if the stock subject
to such merger is designated as a national market system security on an
interdealer quotation system by the Nasdaq Association of Securities Dealers,
Inc. and the consideration to be received in such merger consists of a stock
listed on a national securities exchange or designated as a national market
system security on an interdealer quotation system by the Nasdaq Association of
Securities Dealers, Inc. Because the Nasdaq National Market is designated as
such a system and the Quantum and Meridian common stock are quoted on the
Nasdaq National Market, holders of Meridian common stock are not entitled to
appraisal rights with respect to the merger.

Absence of Quantum Appraisal Rights

  Holders of Quantum common stock are not entitled to appraisal rights under
the DGCL because Quantum is not a constituent corporation to the merger under
the DGCL.

Resale of Quantum Common Stock

  Quantum common stock issued in connection with the merger will be freely
transferable, except that shares issued to a Meridian affiliate or person who
becomes an affiliate of Quantum are subject to certain restrictions on resale.
An affiliate is defined generally as including, without limitation, directors,
certain executive officers and certain other persons who control a company.
Pursuant to the terms of the merger agreement, Meridian has delivered to
Quantum Meridian affiliate agreements executed by the Meridian affiliates that
prohibit the sale, transfer or other disposition of Quantum common stock
received by such Meridian affiliate in the merger or upon exercise of options
assumed by Quantum in the merger, except under certain circumstances, in order
to comply with the requirements of certain federal securities laws. See
"Approval of the Merger and Related Transactions--Meridian Affiliate
Agreements."

                              THE MERGER AGREEMENT

General

  The following is a summary of the material provisions of the merger
agreement, a copy of which is attached as Appendix A to this proxy
statement/prospectus and is incorporated herein by reference. However, the
following is not a complete statement of all provisions of the merger agreement
and related agreements. Statements made in this proxy statement/prospectus with
respect to the terms of the merger agreement and such related agreements are
qualified in their respective entireties by reference to the more detailed
information set forth in the merger agreement and such related agreements.
Capitalized terms used in this summary but not defined in this proxy
statement/prospectus shall have the meanings ascribed to them in the merger
agreement.

  The merger agreement provides for the merger of Defiant Acquisition Sub with
and into Meridian. As a result of the merger, Defiant Acquisition Sub will
cease to exist, Meridian will become a wholly-owned subsidiary of Quantum, and
the former stockholders of Meridian will become stockholders of Quantum.
Meridian, as the surviving corporation, will retain all of its separate
corporate existence, with all its purposes, objects, rights, privileges, powers
and franchises unaffected by the merger. Defiant Acquisition Sub has been
formed solely for the purpose of effecting the merger, and there will be no
other activity in Defiant Acquisition Sub. The merger will become effective at
the effective time, which shall be upon the filing of articles of merger with
the Secretary of State of the State of Delaware or such later time as may be
specified in the articles of merger. The effective time shall occur no later
than the second day after the satisfaction or waiver of all the conditions to
closing set forth in the merger agreement. It is currently anticipated that the
effective time will occur on or before September 10, 1999. There can be no
assurance, however, that the conditions to the merger will be satisfied by such
date, or at all, or that the merger agreement will not be terminated. See "--
Conditions to the Merger."

Merger Consideration

  Meridian Common Stock. At the effective time, each share of Meridian common
stock then outstanding will be converted into the right to receive shares of
Quantum DLT & Storage System group and half as many shares of Hard Disk Drive
group common stock based on the exchange ratio. The actual number of shares of
Quantum DLT & Storage System group and Hard Disk Drive group common stock that
will be issued for each share of Meridian's common stock will be determined by
the sum of (1) the average of the closing sale price of one share of Quantum
DLT & Storage Systems group common stock for the five trading days ending on
the second trading day prior to the Meridian special meeting and (2) the
average of one half of the closing sale price of one share of Hard Disk Drive
group common stock for the same period. If the resulting sum of the average
prices is greater than or equal to $14.00 but less than or equal to $20.00,
then the exchange ratio will be 0.489 such that each share of Meridian common
stock will convert into 0.489 of a share of Quantum DLT & Storage Systems group
common stock and half as much (or 0.2445) of a share of Hard Disk Drive group
common stock. If the average price is less than $14.00, then the exchange ratio
will be determined by dividing $7.00 by the combined average stock price such
that the number of shares of DLT & Storage Systems group common stock issued
for each share of Meridian common stock will equal the exchange ratio and the
number of shares of Hard Disk Drive group common stock issued for each share of
Meridian common stock will be one-half of the exchange ratio.If the combined
average stock price is greater than $20.00, then the exchange ratio will be
determined by dividing $10.00 by the combined average stock price such that the
number of shares of DLT & Storage Systems group common stock issued for each
share of Meridian common stock will equal the exchange ratio and the number of
shares of Hard Disk Drive group common stock issued for each share of Meridian
common stock will be one-half of the exchange ratio. To receive an estimate of
the exchange ratio as of any date prior to and including the date on which the
exchange ratio is finally determined, call Corporate Investor Communications at
1-888-897-0079.

<PAGE>

  The following table shows the exchange ratio based upon a range of the sum of
(1) the average closing price of one share of DLT & Storage Systems group
common stock over the five trading days ending on the day that is two trading
days prior to the Meridian special meeting and (2) the average of one half of
the closing price of one share of Hard Disk Drive group common stock over the
same period, the number of shares of DLT & Storage Systems group and Hard Disk
Drive group common stock issued for one share of Meridian common stock and also
shows the implied value of Meridian common stock in that exchange:

  No Fractional Shares. No fractional shares of Quantum stock will be issued in
connection with the merger, and no certificates for any such fractional shares
will be issued. In lieu of such fractional shares, any holder of Meridian
common stock (after aggregating all fractional shares of Quantum DLT & Storage
Systems group common stock and Hard Disk Drive group common stock issuable to
such stockholder) will, upon surrender of such stockholder's stock
certificate(s) representing Meridian common stock to Harris Bank and Trust,
transfer agent and registrar for Quantum stock and exchange agent for purposes
of the merger (the "exchange agent"), be paid in cash the dollar amount
(rounded to the nearest whole cent), without interest, determined by
multiplying such fraction by the closing price of a share of such class of
Quantum stock on the NYSE on the effective date.

Stock Options

  At the effective time, all outstanding options with respect to Meridian
common stock under Meridian's option plans (collectively, "Meridian options")
shall be converted into and become rights with respect to Quantum DLT & Storage
Systems group and Hard Disk Drive group common stock, and Quantum shall assume
each such option in accordance with the terms (as in effect as of the date of
the merger agreement) of the stock option plan under which it was issued and
the stock option agreement by which it is evidenced. From and after the
effective time,

  .  Each Meridian option assumed by Quantum may be exercised solely for
     shares of Quantum DLT & Storage Systems group and Hard Disk Drive group
     common stock, as applicable

  .  The number of shares of Quantum DLT & Storage Systems group common stock
     subject to each such Meridian option shall be equal to the number of
     shares of Meridian common stock subject to such Meridian option
     immediately prior to the effective time multiplied by the exchange
     ratio, rounding down to the nearest whole share (with cash, less the

  .  The number of shares of Quantum Hard Disk Drive group common stock
     subject to each such Meridian option shall be equal to the number of
     shares of Meridian common stock subject to such Meridian option
     immediately prior to the effective time multiplied by one half of the
     exchange ratio, rounding down to the nearest whole share (with cash,

     of which is the exchange ratio and rounding up to the nearest cent

  .  The per share exercise price for Hard Disk Drive group common stock
     under each Meridian option shall be adjusted by multiplying the per
     share exercise price under such Meridian option by a fraction, the
     numerator of which is .534 and the denominator of which is the exchange

     plan (see "Interests of Certain Persons in the Merger--Meridian
     Severance Plan")

Stock Ownership Following the Merger

  Based upon the number of shares of Meridian common stock and Quantum DLT &
Storage Systems group and Hard Disk Drive group common stock common stock
issued and outstanding on the record date, which excludes outstanding options
and other rights to purchase common stock, if the Meridian special meeting
were to have occurred on August 4, 1999, on which date the exchange ratio
would have been .447, an aggregate of approximately 3,844,101 shares of DLT &
Storage Systems group common stock and 1,922,050 shares of Hard Disk Drive
group common stock would have been issued in connection with the merger,
representing approximately 2.3% of the total number of shares of the
respective classes of Quantum common stock issued and outstanding. The actual
exchange ratio in the merger may be different because the average closing
prices DLT & Storage Systems group and Hard Disk Drive group common stock
fluctuate continuously. If the Quantum combined average stock price at the
time of the Meridian special meeting exceeds $20.48, fewer shares of DLT &
Storage Systems group common stock and Hard Disk Drive group common stock will
be issued in the merger; if the Quantum average stock price at the time of the
Meridian special meeting is less than $14.00, more DLT & Storage Systems group
and Hard Disk Drive group shares will be issued in the merger.

  Based on the number of outstanding options to purchase Meridian common stock
as of the record date and the exchange ratio that would have been in effect if
the Meridian special meeting had been held on August 4, 1999, the total number
of outstanding options to purchase Meridian common stock would have become
rights to purchase an aggregate of 892,521 shares of Quantum common stock in
connection with the merger.

Conversion of Shares; Procedures for Exchange of Certificates

  As soon as practicable after the effective time, the exchange agent will
mail to the registered holders of Meridian common stock (i) a letter of
transmittal and (ii) instructions for the use in effecting the surrender of
valid certificates representing shares of Meridian common stock (the "Meridian
stock certificates") in exchange for certificates representing Quantum DLT &
Storage Systems group common stock and Hard Disk Drive group common stock.
Upon surrender of a Meridian stock certificate to the exchange agent for
exchange, together with a duly executed letter of transmittal and such other
documents as may reasonably be required by the exchange agent or Quantum, the
holder of such Meridian stock certificate shall be entitled to receive in
exchange therefor certificates representing the whole number of shares of DLT
& Storage Systems group common stock and Hard Disk Drive group common stock
that such stockholder has the right to receive. No fractional shares of DLT &
Storage Systems group common stock and Hard Disk Drive group common stock will
be issued in connection with the merger, and no certificates for any such
fractional shares will be issued. See "--Merger Consideration--No Fractional
Shares."

  If any Meridian stock certificate has been lost, stolen or destroyed,
Quantum may require the owner of such lost, stolen or destroyed Meridian stock
certificate to provide an appropriate affidavit and to deliver a bond as
indemnity against any claim that may be made against the exchange agent,
Quantum or Meridian with respect to such Meridian stock certificate.

  Meridian stockholders should not surrender their Meridian stock certificates
for exchange until they receive a letter of transmittal from the exchange
agent.

Effect on Certificates

  At the effective time, (1) all shares of Meridian common stock outstanding
immediately prior to the effective time will automatically be canceled and
retired and will cease to exist, and all holders of certificates representing
shares of Meridian common stock that were outstanding immediately prior to the
effective time will cease to have any rights as stockholders of Meridian, and
(2) the stock transfer books of Meridian will be closed with respect to all
shares of Meridian common stock outstanding immediately prior to the effective
time. No further transfer of any such shares of Meridian common stock will be
made on such stock transfer books after the effective time. If, after the
effective time, a Meridian stock certificate is presented to the exchange agent
(or to Meridian or Quantum), such Meridian stock certificate will be canceled
and will be exchanged as provided above under the caption "--Conversion of
Shares; Procedure for Exchange of Certificates" and "--Merger Consideration."

such a change assuming the Meridian disclosure schedule were dated as of the
date of the occurrence, existence or discovery of such event, condition, fact
or circumstance, then Meridian shall promptly deliver to Quantum an update to

  Non-Solicitation. Pursuant to the merger agreement, Meridian has agreed that
from the date of the merger agreement until the consummation of the merger or
termination of the merger agreement, it will not, directly or indirectly, and
will not authorize or permit any of the other acquired corporations or any
representative of the acquired corporations to:

  .  Solicit, initiate, encourage or induce the making, submission or
     announcement of any acquisition proposal or take any action that could
     be reasonably expected to lead to an acquisition proposal

  .  Furnish any information regarding any of the acquired corporations to
     any person in connection with or in response to an acquisition proposal

  .  Engage in discussions or negotiations with any person with respect to
     any acquisition proposal

  .  Approve, endorse or recommend any acquisition proposal

  .  Enter into any letter of intent or similar document or any contract
     contemplating or otherwise relating to any acquisition transaction

  Meridian is not prevented, however, from (A) disclosing to Meridian's
stockholders a position with respect to a tender offer pursuant to Rule 14d-9
and 14e-2 promulgated under the Exchange Act or (B) furnishing nonpublic
information regarding the acquired corporations to, or entering into
discussions with, any person in response to a superior offer or engaging in
discussions with respect thereto if all of the following conditions are met:

  .  Neither Meridian nor any representative of Meridian shall have violated
     any of its obligations against non-solicitation

  .  The Meridian Board concludes in good faith, based upon the advice of its
     outside counsel, that such action is required in order for the Meridian
     Board to comply with its fiduciary duties under applicable law

  .  Prior to furnishing any nonpublic information to, or entering
     discussions with any person, Meridian gives Quantum written notice of
     the identity of such person and of Meridian's intention to furnish
     nonpublic information to, or enter into discussions with, such person,
     and Meridian receives from such person an executed confidentiality
     agreement containing customary limitations on the use and disclosure of
     all nonpublic written and oral information furnished to such person by
     Meridian

  .  Prior to furnishing any such nonpublic information to, or entering into
     discussions with, such person, Meridian furnishes such nonpublic
     information to Quantum (to the extent such nonpublic information has not
     been previously furnished by Meridian to Quantum).

  In addition to the foregoing, Meridian shall (A) provide Quantum with at
least 48 hours prior notice of any meeting of Meridian's Board at which
Meridian's Board is reasonably expected to consider a superior offer and (B)
not recommend a superior offer to its stockholders for a period of not less
than the greater of three business days or 72 hours after Quantum's receipt of
a copy of such superior offer.

  Meridian shall promptly advise Quantum orally and in writing of any
acquisition proposal (including the identity of the person making or submitting
such acquisition proposal and the terms thereof) that is made or submitted by
any person between May 10, 1999 and the consummation of the merger. Meridian
shall keep Quantum fully informed with respect to the status of any such
acquisition proposal and any modification or proposed modification thereto.

  As of May 10, 1999, Meridian shall immediately cease and cause to be
terminated any existing discussions with any person that relate to any
acquisition proposal.

                                       51

  An "acquisition proposal" is any offer, proposal or inquiry (other than an
offer or proposal by Quantum) contemplating or otherwise relating to any
"acquisition transaction." An "acquisition transaction" is any transaction or
series of related transactions involving: (1) any merger, consolidation,
amalgamation, share exchange, business combination, issuance of securities,
acquisition of securities, tender offer, exchange offer or other similar
transaction (A) in which Meridian is a constituent corporation, (B) in which
any person or "group" (as defined in the Exchange Act and the rules thereunder)
of persons directly or indirectly acquires Meridian or more than 20% of the
company's business or directly or indirectly acquires beneficial or record
ownership of securities representing more than 20% of the outstanding
securities of any class of voting securities of Meridian, or (C) in which any
of the acquired corporations issues securities representing more than 20% of
the outstanding securities of any class of voting securities of Meridian; (2)
any sale, lease, exchange, transfer, license, acquisition or disposition of
more than 20% of the assets of Meridian; or (3) any liquidation or dissolution
of Meridian.

  A "superior offer" is an unsolicited, bona fide written offer made by a third
party to purchase more than 50% of the outstanding shares of Meridian common
stock on terms that the Meridian Board determines, in its reasonable judgment,
after consultation with its financial advisor, to be more favorable to
Meridian's stockholders than the terms of the merger, except that no such offer
shall be deemed to be a "superior offer" if any financing required to
consummate the transaction contemplated by such offer is not committed and is
not likely to be obtained by such third party on a timely basis.

  Proprietary Assets. Pursuant to the merger agreement, Meridian shall use its
best efforts to evaluate whether products it manufactured prior to December 31,
1997 are Year 2000 Compliant, document such compliance or lack thereof, and
assess the financial impact on the Company for liability to third parties for
any products the Company manufactured which are not Year 2000 Compliant.

  The Company shall complete certain annotations listed in the Meridian
Disclosure Schedule by June 10, 1999.

  Termination of Plans. Upon Quantum's request, to the extent permitted under
applicable law and applicable contracts and the terms of such plan (including
but not limited to the Meridian's 401(k) Plan), Meridian will terminate any
plan immediately prior to the closing of the merger.

  Ratification of Delaware Reincorporation. The 1997 reincorporation of
Meridian in the State of Delaware shall have been ratified by the affirmative
vote of the holders of a majority of the shares of Meridian common stock
outstanding on the record date.

  Meeting of Stockholders. Pursuant to the merger agreement, Meridian will take
all action necessary in accordance with applicable law to convene and hold the
Meridian special meeting to vote upon the approval of the merger agreement and
the merger. Meridian's obligation to call, give notice of, convene and hold the
Meridian special meeting will not be limited or otherwise affected by the
commencement, disclosure announcement or submission to Meridian of an
acquisition proposal or by the withdrawal, amendment or modification of the
recommendation of the Meridian Board with respect to the merger.

  Neither the board of directors of Meridian nor any committee thereof is
permitted to withdraw, amend or modify, or propose or resolve to withdraw,
amend or modify, in a manner adverse to the other party, its recommendations in
favor of the merger agreement and the merger. However, notwithstanding the
foregoing, the Meridian Board will not be prevented from withdrawing, amending
or modifying its unanimous recommendation in favor of the merger if (1) a
superior offer is made to Meridian and is not withdrawn, (2) neither Meridian
nor any of its representatives has violated the covenants given by them
concerning non-solicitation, (3) the Meridian Board concludes in good faith,
based upon the advice of its outside counsel, that, in light of such superior
offer, the withdrawal, amendment or modification of such recommendation is
required in order for the Meridian Board to comply with its fiduciary
obligations, (4) Meridian provides Quantum with at least 48 hours notice of any
meeting of Meridian's board of directors at which the board is expected to

                                       52
<PAGE>

consider a superior proposal, and (5) Meridian's board of directors does not
withdraw, amend or modify its unanimous recommendation in favor of the merger
for at least 72 hours after Meridian provides Quantum with the name of the
person or entity making the superior offer and a copy of that offer.

  Conditions Relating to Stock Options. For a description of the treatment of
stock options to purchase Meridian common stock, see the caption above entitled
"--Stock Options."

  Form S-8. Pursuant to the merger agreement, Quantum has agreed to file a
registration statement on Form S-8 for the shares of the Quantum stock issuable
with respect to assumed Meridian options promptly after the effective time.

  Indemnification and Insurance. Pursuant to the merger agreement, all rights
to indemnification existing in favor of the persons serving as directors or
officers of Meridian as of the date of the merger agreement for acts and
omissions occurring prior to the effective time, as provided in the Meridian
bylaws and as provided in any indemnification agreements between Meridian and
said officers and directors shall survive the merger and shall be observed by
Quantum and the surviving corporation for a period of not less than six years
from the effective time. The merger agreement also provides that from the
effective time until the third anniversary of the date on which the merger
becomes effective, the surviving corporation shall maintain in effect, for the
benefit of the persons serving as directors and officers of Meridian as of the
date of the merger agreement with respect to acts or omissions occurring prior
to the effective time, the lesser of (1) the existing policy of directors' and
officers' liability insurance maintained by Meridian as of the date of the
merger agreement (the "existing policy") and (2) the amount of coverage
purchased by 150% of the amount of the last annual premium paid by Meridian
prior to the date of the merger agreement for the existing policy; provided,
however, that the surviving corporation may substitute for the existing policy
a policy or policies of comparable coverage.

  Certain Other Covenants. The merger agreement contains certain other
covenants including covenants relating to: (i) preparation and filing of the
registration statement; (ii) obtaining regulatory approvals; (iii) public
announcements; (iv) tax qualification and opinion back-up certificates; (v)
resignation of officers and directors of Meridian; (vi) employee service
credit; and (vii) listing of the Quantum common stock to be issued pursuant to
the merger on the New York Stock Exchange.

Termination

  The merger agreement may be terminated prior to the effective time (whether
before or after approval of the merger agreement and the merger by the Meridian
stockholders):

  .  By mutual written consent duly authorized by the Boards of Directors of
     the Quantum and Meridian

  .  By either Quantum or Meridian if the merger shall not have been
     consummated by December 31, 1999 (unless the failure to consummate the
     merger is substantially attributable to a failure to act on the part of
     the party seeking to terminate the merger agreement to perform any
     material obligation required to be performed by such party at or prior
     to the effective time)

  .  By either Quantum or Meridian if a court of competent jurisdiction or
     other governmental body shall have issued a final and non-appealable
     order, decree or ruling, or shall have taken any other action, having
     the effect of permanently restraining, enjoining or otherwise
     prohibiting the merger

  .  By either Quantum or Meridian if (A) the Meridian special meeting shall
     have been held (either on the date for which such meeting was originally
     scheduled or pursuant to any permissible adjournment or postponement)
     and (B) the merger agreement and the merger shall not have been adopted
     and approved at such meeting by the necessary vote of the Meridian
     stockholders (provided that the right to terminate the merger agreement
     on this basis shall not be available to Meridian where the failure to
     obtain stockholder approval shall have been caused by the action or
     failure to act of Meridian and such action or failure to act constitutes
     a material breach by Meridian of the merger agreement and unless
     Meridian makes the required termination payments)

                                       53
<PAGE>

  .  By Quantum (at any time prior to the adoption and approval of the merger
     agreement and the merger by the necessary vote of the Meridian
     stockholders) if a triggering event shall have occurred

  .  By Quantum if any of Meridian's representations and warranties contained
     in the merger agreement shall be or shall have become inaccurate, or if
     any of Meridian's covenants contained in the merger agreement shall have
     been breached; provided, however, that if an inaccuracy in Meridian's
     representations and warranties or a breach of a covenant by Meridian is
     curable by Meridian and Meridian is continuing to exercise all
     reasonable efforts to cure such inaccuracy or breach, then Quantum may
     not terminate the merger agreement on this basis on account of such
     inaccuracy or breach unless Meridian fails to cure the inaccuracy or
     breach within 30 days of notice from Quantum

  .  By Meridian if any of Quantum's representations and warranties contained
     in the merger agreement shall be or shall have become inaccurate, or if
     any of Quantum's covenants contained in the merger agreement shall have
     been breached; provided, however, that if an inaccuracy in Quantum's
     representations and warranties or a breach of a covenant by Quantum is
     curable by Quantum and Quantum is continuing to exercise all reasonable
     efforts to cure such inaccuracy or breach, then Meridian may not
     terminate the merger agreement on this basis on account of such
     inaccuracy or breach unless Quantum fails to cure such inaccuracy or
     breach within 30 days after receiving notice from Meridian

  A "triggering event" shall be deemed to have occurred if:

  .  The Meridian Board shall have failed to recommend, or shall for any
     reason have withdrawn or shall have amended or modified in a manner
     adverse to Quantum its unanimous recommendation in favor of, the
     adoption and approval of the merger agreement or the approval of the
     merger

  .  Meridian shall have failed to include in this proxy statement/prospectus
     the unanimous recommendation of the Meridian Board in favor of the
     adoption and approval of the merger agreement and the approval of the
     merger

  .  The Meridian Board fails to reaffirm its unanimous recommendation in
     favor of the adoption and approval of the merger agreement and the
     approval of the merger within ten business days after Quantum requests
     in writing that such recommendation be reaffirmed

  .  The Meridian Board shall have approved, endorsed or recommended any
     acquisition proposal

  .  Meridian shall have entered into any letter of intent of similar
     document or any contract relating to any acquisition proposal

  .  Meridian shall have failed to hold the Meridian special meeting as
     promptly as practicable and in any event within 45 days after the latest
     of (A) the date the registration statement is declared effective under
     the Securities Act, or (B) the Quantum special meeting relating to the
     tracking stock proposal.

  .  A tender or exchange offer relating to securities of Meridian shall have
     been commenced and Meridian shall not have sent to its securityholders,
     within ten business days after the commencement of such tender or
     exchange offer, a statement disclosing that Meridian recommends
     rejection of such tender or exchange offer

  .  An acquisition proposal is publicly announced, and Meridian (A) fails to
     issue a press release announcing its opposition to such acquisition
     proposal within ten business days after such acquisition proposal is
     announced or (B) otherwise takes actions inconsistent with opposing such
     acquisition proposal

  .  Meridian breaches or is deemed to have breached any of its non-
     solicitation obligations under the merger agreement

                                       54

Expenses and Termination Fees

  Pursuant to the merger agreement, all fees and expenses incurred in
connection with the merger agreement and the transactions contemplated by the
merger agreement shall be paid by the party incurring such expenses, whether or
not the merger is consummated; provided, however, that Quantum and Meridian
shall share equally all fees and expenses, other than attorneys' fees, incurred
in connection with the filing, printing and mailing of this proxy
statement/prospectus and any amendments or supplements thereto.

  If (A) the merger agreement is terminated by Quantum or Meridian pursuant to
the provision of the merger agreement which permits termination if the Meridian
special meeting shall have been held and the merger agreement and the merger

(2) a proposed Meridian acquisition is publicly announced, in either case prior
May 10, 2000, or (B) the merger agreement is terminated by Quantum pursuant to
the provision of the merger agreement which permits termination if a triggering
event shall have occurred, then Meridian shall pay to Quantum, in cash, a
nonrefundable fee equal to $4,550,000.

                                   PROPOSAL 2

                                RATIFICATION OF
                        1997 REINCORPORATION IN DELAWARE

Introduction

  On February 28, 1997, Meridian's board of directors solicited the
shareholders of Meridian to approve a proposal to change Meridian's state of
incorporation from California to Delaware. The Meridian board believed that
this reincorporation would be in the best interests of Meridian and its
shareholders in that they would benefit from the well established principles of
corporate governance that Delaware law affords. The reincorporation was to be
effected by merging Meridian California with and into its wholly-owned
subsidiary, Meridian Delaware. Upon completion of the reincorporation merger,
Meridian California would cease to exist and Meridian Delaware would continue
to operate the business of Meridian under the name Meridian Data, Inc.

  Through a review of corporate documents conducted as part of the due
diligence process in connection with the Merger, it was discovered that the
proxy statement sent to the Meridian shareholders in connection with the
reincorporation proposal incorrectly set forth the vote required under
California law to obtain shareholder approval for the reincorporation proposal.
The proxy statement stated that the approval of the reincorporation proposal
would require the affirmative vote of a majority of the shares represented and
voting at the meeting. However, under California law the reincorporation
proposal required the approval of a majority of all shares outstanding and
entitled to vote on the reincorporation proposal, including those shares which
were not present and voting at the meeting. A majority of the votes cast
approved the reincorporation proposal which, according to the legal standard
set forth in the proxy statement, was sufficient to effect the reincorporation
merger. However, due to a substantial number of broker non-votes, the approval
of a majority of all shares outstanding and entitled to vote on the
reincorporation merger was not obtained. Accordingly, the 1997 reincorporation
proposal failed to receive the requisite number of votes under California law.

  Under the belief that the reincorporation proposal had been approved by
Meridian's shareholders in accordance with California law, Meridian filed the
requisite reincorporation documents with the Secretaries of State of California
and Delaware to effect the reincorporation merger. Based on a review of the
corporation laws of California and Delaware, Meridian believes the
reincorporation merger was effective upon the filing of such corporate
documents and that Meridian is a Delaware corporation and has been such since
May 1997, notwithstanding the failure to obtain the requisite number of votes
needed under California law.

  However, under Delaware and California case law, because the reincorporation
proposal failed to obtain the requisite shareholder vote necessary for
approval, the reincorporation merger is voidable and is susceptible to
challenge. If any such challenge were to be successful, a court could nullify
or rescind the reincorporation merger, thereby reinstating Meridian as a
California corporation. Under applicable corporate law, a transaction that is
voidable may be ratified by obtaining the approval, after the fact, of the
affirmative vote of the stockholders necessary to approve the challenged
transaction. Accordingly, Meridian is seeking the approval of its stockholders
to ratify the 1997 reincorporation in order to cure the failure to obtain the
requisite shareholder vote in connection with the 1997 reincorporation.

  In addition, Quantum has the ability to avoid consummating the merger if
Meridian's stockholders do not ratify the 1997 reincorporation. The merger
agreement requires Meridian to remedy the failure to obtain the requisite
shareholder approval such that Meridian Delaware shall be the principal
company. The merger agreement also contains a closing condition to the merger
that requires Meridian Delaware to succeed to all of the rights, privileges,
powers and franchises of Meridian California. Accordingly, a vote against the
ratification of the 1997 reincorporation will have the same effect as a vote
against the merger.

Principal Reasons For The Ratification Of The 1997 Reincorporation

  The Meridian board believes that it is essential for the Meridian
stockholders to ratify the 1997 reincorporation in order to cure the failure to
obtain the requisite shareholder vote in connection with the 1997
reincorporation and to comply with the provisions of the merger agreement and
to successfully complete the Merger transaction. The failure to obtain the
sufficient stockholder vote to ratify the 1997 reincorporation would not by
itself result in the rescission or nullification of the 1997 reincorporation,
but the 1997 reincorporation would remain voidable and Quantum would be
entitled to terminate the merger agreement at its option.

  Avoid the Voidability of the 1997 Reincorporation. Until the 1997
reincorporation is ratified by Meridian's stockholders, the 1997
reincorporation will remain voidable upon a successful challenge. Stockholder
ratification would cure the failure to obtain the requisite shareholder vote in
connection with the 1997 reincorporation and would protect the 1997
reincorporation from the threat of a potential challenge.

  Approval of the Merger. The Meridian board and management believe that it is
in the best interests of Meridian and its stockholders to consummate the Merger
with Quantum. Since the ratification of the 1997 reincorporation is set forth
in the merger agreement as a condition precedent to the closing of the merger,
the merger agreement may be terminated at Quantum's option if the Meridian
stockholders do not ratify the 1997 reincorporation. Accordingly, a vote
against the ratification of the 1997 reincorporation will have the same effect
as a vote against the merger.

Principal Reasons For The 1997 Reincorporation

  In 1997 the Meridian board and management asked Meridian's shareholders to
approve the ratification proposal because they believed that it is essential to
be able to draw upon well established principles of corporate governance in
making legal and business decisions. The Meridian board and management believed
that the prominence and predictability of Delaware corporate law would provide
a reliable foundation on which Meridian's governance decisions would be based,
and Meridian believed that its shareholders would benefit from the
responsiveness of Delaware corporate law to their needs and to those of the
corporation they own. For these reasons, the Meridian board and management
continues to believe that the 1997 reincorporation was and is in the best
interests of Meridian and its stockholders.

  Prominence, Predictability and Flexibility of Delaware Law. For many years
Delaware has followed a policy of encouraging incorporation in that state and
in furtherance of that policy, has been a leader in adopting, construing and
implementing comprehensive, flexible corporate laws responsive to the legal and
business needs of corporations organized under its laws. Many corporations have
chosen Delaware initially as a state of incorporation or have subsequently
changed corporate domicile to Delaware in a manner similar to that undertaken
by Meridian. Because of Delaware's prominence as the state of incorporation for
many major corporations, both the legislature and courts in Delaware have
demonstrated an ability and a willingness to act quickly and effectively to
meet changing business needs. The Delaware courts have developed considerable
expertise in dealing with corporate issues and a substantial body of case law
has developed construing Delaware law and establishing public policies with
respect to corporate legal affairs.

  Increased Ability to Attract and Retain Qualified Directors. Both California
and Delaware law permit a corporation to include a provision in its certificate
of incorporation that reduces or limits the monetary liability of directors for
breaches of fiduciary duty in certain circumstances. The increasing frequency
of claims and litigation directed against directors and officers has greatly
expanded the risks facing directors and officers of corporations in exercising
their respective duties. The amount of time and money required to respond to
such claims and to defend such litigation can be substantial. It was Meridian's
desire to reduce these risks to its directors and officers and to limit
situations in which monetary damages can be recovered against directors so that
Meridian could continue to attract and retain qualified directors who otherwise
might be unwilling to serve because of the risks involved. Meridian believes
that, in general, Delaware law provides greater protection to

                                       57
<PAGE>

directors than California law and that Delaware case law regarding a
corporation's ability to limit director liability is more developed and
provides more guidance than California law.

  Well Established Principles of Corporate Governance. There is substantial
judicial precedent in the Delaware courts as to the legal principles applicable
to measures that may be taken by a corporation and as to the conduct of the
Meridian board under the business judgment rule. Meridian believes that its
shareholders have benefited from the well established principles of corporate
governance that Delaware law affords.

The 1997 reincorporation did not result in any change in Meridian's name, board
members, business, management, employee plans or location of principal
facilities.

  The 1997 reincorporation effected a change in the legal domicile of Meridian,
but not its physical location. The 1997 reincorporation did not result in any
change in the name, business, management, fiscal year, assets or liabilities
(except to the extent of legal and other costs of effecting the
reincorporation) or location of the principal facilities of Meridian. The five
directors who were elected at Meridian's Annual Meeting of Shareholders in 1997
became the directors of Meridian Delaware. All employee benefit plans of
Meridian California were assumed and continued by Meridian Delaware. All stock
options, warrants or other rights to acquire common stock of Meridian
California were automatically converted into an option or right to purchase the
same number of shares of Meridian Delaware common stock at the same price per
share, upon the same terms, and subject to the same conditions. Meridian
California's other employee benefit arrangements were also continued by
Meridian Delaware upon the terms and subject to the conditions in effect before
the reincorporation.

Antitakeover Implications Of The 1997 Reincorporation

  Delaware, like many other states, permits a corporation to adopt a number of
measures through amendment of the certificate of incorporation or bylaws or
otherwise, which measures are designed to reduce a corporation's vulnerability
to unsolicited takeover attempts. The 1997 reincorporation was not proposed in
order to prevent an unsolicited takeover attempt, nor was it in response to any
attempt known to the Meridian board to acquire control of Meridian, obtain
representation on the Meridian board or take significant action that affects
Meridian.

  Nevertheless, certain effects of the 1997 reincorporation may have had
antitakeover implications. Section 203 of the Delaware General Corporation Law
("Section 203"), from which Meridian Delaware did not opt out, restricts
certain "business combinations" with "interested stockholders" for three years
following the date that a person or entity becomes an interested stockholder,
unless the Meridian board approves the business combination and/or other
requirements are met. See "Significant Differences Between the Corporation Laws
of California and Delaware--Stockholder Approval of Certain Business
Combinations." Furthermore, the elimination of cumulative voting could have an
antitakeover effect in that it can make it more difficult for a minority
shareholder to gain a seat on the Meridian board. Other measures permitted
under Delaware law, which Meridian did implement, include the establishment of
a staggered board of directors and the elimination of the right of stockholders
controlling at least ten percent (10%) of the voting shares to call a special
meeting of stockholders. The elimination of cumulative voting and the
establishment of a classified board of directors can also be undertaken under
California law in certain circumstances.

  In addition, Delaware law permits a corporation to adopt such measures as
stockholder rights plans, designed to reduce a corporation's vulnerability to
unsolicited takeover attempts. There is substantial judicial precedent in the
Delaware courts as to the legal principles applicable to such defensive
measures and as to the conduct of a board of directors under the business
judgment rule with respect to unsolicited takeover attempts. On July 18, 1997,
the Meridian board of directors adopted a Rights Plan in order to deter
unwanted takeovers. The Rights Plan was executed on August 11, 1997. On May 14,
1999, the Rights Plan was amended to remove a "Dead Hand" provision held to be
invalid under Delaware law. The Meridian board did not amend the Certificate of
Incorporation or bylaws to include provisions that might deter an unsolicited
takeover attempt.

                                       58
<PAGE>

However, in the discharge of its fiduciary obligations to its shareholders, the
Meridian board has continued to evaluate Meridian's vulnerability to potential
unsolicited bids to acquire Meridian on unfavorable terms and to consider
strategies to enhance the board's ability to negotiate with an unsolicited
bidder.

The Charters And Bylaws Of Meridian California And Meridian Delaware

  The provisions of the Meridian Delaware Certificate of Incorporation and
bylaws are similar to those of the Meridian California Articles of
Incorporation and bylaws in many respects. However, the 1997 reincorporation
included the authorization of undesignated Preferred Stock and the
implementation of certain provisions in the Meridian Delaware Certificate of
Incorporation and bylaws that altered the rights of stockholders and the powers
of management.

  Authorization of Preferred Stock. The Articles of Incorporation of Meridian
California authorized Meridian California to issue up to 35,000,000 shares of
Common Stock, no par value. The Certificate of Incorporation of Meridian
Delaware provides that Meridian Delaware has 35,000,000 authorized shares of
Common Stock, $.001 par value, and 5,000,000 shares of Preferred Stock, $.001
par value. In addition, Meridian Delaware's Certificate of Incorporation
provides that the Meridian board is entitled to determine the powers,
preferences and rights, and the qualifications, limitations or restrictions, of
the authorized and unissued preferred stock. Thus, although it has not done so
and has no present intention of doing so, the Meridian board, without
stockholder approval, could authorize the issuance of Preferred Stock upon
terms which could have the effect of delaying or preventing a change in control
of Meridian or modifying the rights of holders of Meridian's Common Stock under
either California or Delaware law. The Meridian board could also utilize such
shares for further financings, possible acquisitions and other uses.

  Monetary Liability of Directors. The Articles of Incorporation of Meridian
California and the Certificate of Incorporation of Meridian Delaware both
provide for the elimination of personal monetary liability of directors to the
fullest extent permissible under law. The provisions eliminating monetary
liability of directors set forth in the Meridian Delaware Certificate of
Incorporation are potentially more expansive than the corresponding provisions
in the Meridian California Articles of Incorporation, in that the former
incorporates future amendments to Delaware law with respect to the elimination
of such liability. For a more detailed explanation of the foregoing, see
"Significant Differences Between the Corporation Laws of California and
Delaware--Indemnification and Limitation of Liability."

  Size of the Meridian Board. The bylaws of Meridian Delaware provide for a
Meridian board consisting of a range of five to seven directors currently set
at five directors. The bylaws of Meridian California provided for a Meridian
board consisting of a range of four to seven directors and was set at five
directors at the time of the 1997 reincorporation. Under California law,
although changes in the number of directors, in general, must be approved by a
majority of the outstanding shares, the Meridian board may fix the exact number
of directors within a stated range set forth in the Articles of Incorporation
or bylaws, if the stated ranges have been approved by the shareholders.
Delaware law permits the board of directors acting alone to change the
authorized number 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 Meridian Delaware
Certificate of Incorporation provides that the number of directors will be as
specified in the bylaws and authorizes the Meridian board to adopt, alter,
amend or repeal the bylaws. The board of directors of Meridian Delaware could
amend the bylaws to change the size of the Meridian board from five without
further stockholder approval. When the 1997 reincorporation occurred, the five
directors of Meridian California who were elected at the Annual Meeting of
Shareholders continued as the five directors of Meridian Delaware after the
1997 reincorporation was consummated.

  Action by Written Consent of Shareholders. Under both California law and
Delaware law, unless otherwise provided in the Articles of Incorporation
(California) or Certificate of Incorporation (Delaware), any action that may be
taken by the shareholders at any annual or special meeting may be taken without
a meeting by written consent of a majority of the holders of the outstanding
shares. The Articles of Incorporation of

                                       59
<PAGE>

Meridian California did not eliminate the ability of its shareholders to act by
written consent. The Certificate of Incorporation of Meridian Delaware provides
that no action shall be taken by the stockholders of the corporation except at
an annual or special meeting of the stockholders and that no action shall be
taken by the stockholders by written consent.

  Cumulative Voting for Directors. Under California law, if any shareholder has
given notice of an intention to cumulate votes for the election of directors,
any other shareholder of the corporation is also entitled to cumulate his or
her votes at such election. Cumulative voting provides that each share of stock
normally having one vote is entitled to a number of votes equal to the number
of directors to be elected. A shareholder may then cast all such votes for a
single candidate or may allocate them among as many candidates as the
shareholder may choose. In the absence of cumulative voting, the holders of a
majority of the shares present or represented at a meeting in which directors
are to be elected would have the power to elect all the directors to be elected
at such meeting, and no person could be elected without the support of holders
of a majority of the shares present or represented at such meeting. Elimination
of cumulative voting could make it more difficult for a minority shareholder
adverse to a majority of the shareholders to obtain representation on
Meridian's Meridian board. California corporations whose stock is listed on a
national stock exchange or whose stock is held by 800 shareholders of record
and included in the Nasdaq National Market System (a "Listed Company") can also
eliminate cumulative voting with shareholder approval. Meridian qualifies as a
Listed Company but has not sought shareholder approval to eliminate cumulative
voting. Under Delaware law, cumulative voting in the election of directors is
not mandatory, but is a permitted option. The Meridian Delaware Certificate of
Incorporation does not provide for cumulative voting rights.

  Power to Call Special Shareholders' Meetings. Under California law, a special
meeting of shareholders may be called by the Meridian board, the Chairman of
the Board, the President, the holders of shares entitled to cast not less than
ten percent (10%) of the votes at such meeting and such additional persons as
are authorized by the articles of incorporation or the bylaws. Under Delaware
law, a special meeting of stockholders may be called by the Meridian board or
by any other person authorized to do so in the Certificate of Incorporation or
the bylaws. The bylaws of Meridian Delaware currently authorizes the Meridian
board, the Chairman of the Board, the President and the holders of not less
than ten percent (10%) of the shares entitled to vote to call a special meeting
of stockholders. Therefore, no substantive change is contemplated in this
provision, although the board could in the future amend Meridian's bylaws
without stockholder approval.

  Filling Vacancies on the Meridian Board. Under California law, any vacancy on
the board of directors other than one created by removal of a director may be
filled by the board. If the number of directors is less than a quorum, a
vacancy may be filled by the unanimous written consent of the directors then in
office, by the affirmative vote of a majority of the directors at a meeting
held pursuant to notice or waivers of notice or by a sole remaining director. A
vacancy created by removal of a director may be filled by the board only if so
authorized by a corporation's articles of incorporation or by a bylaw approved
by the corporation's shareholders. Meridian California's Articles of
Incorporation and bylaws did not permit directors to fill vacancies created by
removal of a director. 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) or by a sole remaining director, unless otherwise
provided in the certificate of incorporation or bylaws (or unless the
certificate of incorporation directs that a particular class of stock is to
elect such directors), in which case a majority of the directors elected by
such class, or a sole remaining director so elected, shall fill such vacancy or
newly created directorship). The bylaws of Meridian Delaware provide,
consistent with the bylaws of Meridian California, that any vacancy created by
the removal of a director by the stockholders of Meridian Delaware may be
filled only by the stockholders. Following the 1997 reincorporation, the board
of directors of Meridian Delaware could, although it has not done so, amend its
bylaws to provide that directors may fill any vacancy created by removal of
directors by the stockholders.

  Loans to Officers and Employees. Under California law, any loan or guaranty
to or for the benefit of a director or officer of the corporation or its parent
requires approval of the shareholders unless such loan or

                                       60
<PAGE>

guaranty is provided under a plan approved by shareholders owning a majority of
the outstanding shares of the corporation. However, under California law,
shareholders of any corporation with 100 or more shareholders of record, such
as Meridian, may approve a bylaw authorizing the Meridian board alone to
approve loans or guarantees to or on behalf of officers (whether or not such
officers are directors) if the board determines that any such loan or guaranty
may reasonably be expected to benefit the corporation. The bylaws of Meridian
California did not contain the foregoing provision. Pursuant to the Meridian
Delaware bylaws and in accordance with Delaware law, Meridian Delaware 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.

  Voting by Ballot. California law provides that the election of directors may
proceed in the manner described in a corporation's bylaws. Meridian
California's bylaws provided that the election of directors at a shareholders'
meeting may be by voice vote or ballot, unless prior to such vote a shareholder
demands a vote by ballot, in which case such vote must be by ballot. Under
Delaware law, the right to vote by written ballot may be restricted if so
provided in the Certificate of Incorporation. The Certificate of Incorporation
of Meridian Delaware provides that elections shall not be held by ballot unless
the bylaws of the corporation so provide. The bylaws of Meridian Delaware do
not provide for voting by ballot. It may be more difficult for a stockholder to
contest the outcome of a vote that has not been conducted by written ballot.

Significant Differences Between The Corporation Laws Of California And Delaware

  The corporation laws of California and Delaware differ in many respects.
Although all the differences are not set forth in this proxy
statement/prospectus, certain provisions which could materially affect the
rights of Meridian stockholders, are discussed below. However, subsequent to
the 1997 reincorporation Meridian has not taken any action which would have
been prohibited or resulted in a different outcome had Meridian been a
California corporation rather than a Delaware corporation.

  Stockholder Approval of Certain Business Combinations. In recent years, a
number of states have adopted special laws designed to make certain kinds of
"unfriendly" corporate takeovers, or other transactions involving a corporation
and one or more of its significant shareholders, more difficult. Under Section
203, certain "business combinations" with "interested stockholders" of Delaware
corporations are subject to a three-year moratorium unless specified conditions
are met.

  Section 203 prohibits a Delaware corporation from engaging in a "business
combination" with an "interested stockholder" for three years following the
date that such person or entity becomes an interested stockholder. With certain
exceptions, an interested stockholder is a person or entity who or which owns,
individually or with or through certain other persons or entities, fifteen
percent (15%) or more of the corporation's outstanding voting stock (including
any rights to acquire stock pursuant to an option, warrant, agreement,
arrangement or understanding, or upon the exercise of conversion or exchange
rights, and stock with respect to which the person has voting rights only), or
is an affiliate or associate of the corporation and was the owner, individually
or with or through certain other persons or entities, of fifteen percent (15%)
or more of such voting stock at any time within the previous three years, or is
an affiliate or associate of any of the foregoing.

  For purposes of Section 203, the term "business combination" is defined
broadly to include mergers with or caused by the interested stockholder, sales
or other dispositions to the interested stockholder (except proportionately
with the corporation's other stockholders) of assets of the corporation of a
director indirect majority-owned subsidiary equal in aggregate market value to
ten percent (10%) or more of the aggregate market value of either the
corporation's consolidated assets or all of its outstanding stock; the issuance
of transfer by the corporation or a direct or indirect majority-owned
subsidiary of stock of the corporation or such subsidiary to the interested
stockholder (except for certain transfers in a conversion or exchange or a pro
rata distribution or certain other transactions, none of which increase the
interested stockholder's proportionate

                                       61
<PAGE>

ownership of any class or series of the corporation's or such subsidiary's
stock or of the corporation's voting stock); or receipt by the interested
stockholder (except proportionately as a stockholder), directly or indirectly,
of any loans, advances, guarantees, pledgees or other financial benefits
provided by, or through the corporation or a subsidiary.

  The three-year moratorium imposed on business combinations by Section 203
does not apply if: (i) prior to the date on which such stockholder becomes an
interested stockholder the board of directors approves either the business
combination or the transaction that resulted in the person or entity becoming
an interested stockholder; (ii) upon consummation of the transaction that made
him or her an interested stockholder, the interested stockholder owns at least
eighty-five percent (85%) of the corporation's voting stock outstanding at the
time the transaction commenced (excluding from the eighty-five percent (85%)
calculation shares owned by directors who are also officers of the target
corporation and shares held by employee stock plans that do not give employee
participants the right to decide confidentially whether to accept a tender or
exchange offer); or (iii) on or after the date such person or entity becomes an
interested stockholder, the board approves the business combination and it is
also approved at a stockholder meeting by sixty-six and two-thirds percent (66
2/3%) of the outstanding voting stock not owned by the interested stockholder.

  Section 203 only applies to certain publicly held corporations that have a
class of voting stock that is (i) listed on a national securities exchange,
(ii) quoted on an interdealer quotation system of a registered national
securities association or (iii) held of record by more than 2,000 stockholders.
Although a Delaware corporation to which Section 203 applies may elect not to
be governed by Section 203, Meridian Delaware has not so elected. Section 203
is not applicable to the Merger.

  Section 203 will encourage any potential acquiror to negotiate with the
Meridian board. Section 203 also might have the effect of limiting the ability
of a potential acquiror to make a two-tiered bid for Meridian Delaware in which
all stockholders would not be treated equally. The application of Section 203
to Meridian Delaware confers upon the Meridian board the power to reject a
proposed business combination in certain circumstances, even though a potential
acquiror may be offering a substantial premium for Meridian Delaware's shares
over the then-current market price. Section 203 would also discourage certain
potential acquirors unwilling to comply with its provisions.

  Removal of Directors. Under California law, any director 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; however, no individual
director may be removed (unless the entire board is removed) if the number of
votes cast against such removal would be sufficient to elect the director under
cumulative voting. 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 at an election of directors. 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 shares
voted 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. The Certificate of Incorporation of Meridian
Delaware does not provide for a classified board of directors or for cumulative
voting.

  Classified Board of Directors. A classified board is one on which a certain
number, but not all, of the directors are elected on a rotating basis each
year. This method of electing directors makes changes in the composition of the
board of directors more difficult and thus a potential change in control of a
corporation a lengthier and more difficult process. Pursuant to legislation
that became effective on January 1, 1990, California law now permits certain
qualifying corporations to provide for a classified board of directors by
adopting amendments to their articles of incorporation or bylaws, which
amendments must be approved by the shareholders. Although Meridian California
qualified to adopt a classified board of directors, its board of directors did
not do so. Delaware law permits, but does not require, a classified board of
directors, pursuant to which the directors can be divided into as many as three
classes with staggered terms of office, with only one

                                       62
<PAGE>

class of directors standing for election each year. The Meridian Delaware
Certificate of Incorporation and bylaws do not provide for a classified board
and Meridian Delaware presently does not have, and does not intend to propose
establishment of, a classified board. The establishment of a classified board
of directors would require the approval of the stockholders of Meridian
Delaware.

  Indemnification and Limitation of Liability. California 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,
with certain exceptions, a corporation to adopt a provision in its articles of
incorporation or certificate of incorporation, as the case may be, eliminating
the liability of a director to the corporation or its shareholders for monetary
damages for breach of the director's fiduciary duty. There are nonetheless
certain differences between the laws of the two states respecting
indemnification and limitation of liability.

  The Articles of Incorporation of Meridian California eliminated the liability
of directors to the corporation to the fullest extent permissible under
California law. California law does not permit the elimination of monetary
liability where such liability is based on: (a) intentional misconduct or
knowing and culpable violation of law; (b) acts or omissions that a director
believes to be contrary to the best interests of the corporation or its
shareholders, or that involve the absence of good faith on the part of the
director; (c) receipt of an improper personal benefit; (d) acts or omissions
that show reckless disregard for the director's duty to the corporation or its
shareholders, where the director in the ordinary course of performing a
director's duties should be aware of a risk of serious injury to the
corporation or its shareholders; (e) acts or omissions that constitute an
unexcused pattern of inattention that amounts to an abdication of the
director's duty to the corporation and its shareholders; (f) interested
transactions between the corporation and a director in which a director has a
material financial interest; and (g) liability for improper distributions,
loans or guarantees.

  The Certificate of Incorporation of Meridian Delaware also eliminates the
liability of directors to the corporation or its stockholders for monetary
damages for breach of fiduciary duty as a director 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; 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 Meridian Delaware or
its directors 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.

  California law permits indemnification of expenses incurred in derivative or
third-party actions, except that with respect to derivative actions (a) no
indemnification may be made when a person is adjudged liable to the corporation
in the performance of that person's duty to the corporation and its
shareholders unless a court determines such person is entitled to indemnify for
expenses, and then such indemnification may be made only to the extent that
such court shall determine, and (b) no indemnification may be made without
court approval in respect of amounts paid or expenses incurred in settling or
otherwise disposing of a threatened or pending action or amounts incurred in
defending a pending action that is settled or otherwise disposed of without
court approval.

  California law requires indemnification when the individual has defended
successfully the action on the merits (as opposed to Delaware law, which
requires indemnification relating to a successful defense on the merits or
otherwise).

  Delaware law generally permits indemnification of expenses, including
attorney's fees, actually and reasonably incurred in the defense or settlement
of a derivative or third-party action, provided there is a determination by a
majority vote of 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 California law) not opposed to the best interests
of

                                       63
<PAGE>

the corporation. 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 or her duty to
the corporation. Delaware law requires indemnification of expenses when the
individual being indemnified has successfully defended any action, claim,
issue, or matter therein, on the merits or otherwise.

  Expenses incurred by an officer or director in defending an action maybe paid
in advance, under Delaware law and California law, if such director or officer
undertakes to repay such amounts if it is ultimately determined that he or she
is not entitled to indemnification. In addition, the laws of both states
authorize a corporation's purchase of indemnity insurance for the benefit of
its officers, directors, employees and agents whether or not the corporation
would have the power to indemnify against the liability covered by the policy.

  California law permits a California corporation to provide rights to
indemnification beyond those provided therein to the extent such additional
indemnification is authorized in the corporation's articles of incorporation.
Thus, if so authorized, rights to indemnification may be provided pursuant to
agreements or bylaw provisions that make mandatory the permissive
indemnification provided by California law. Under California law, there are two
limitations on such additional rights to indemnification: (i) such
indemnification is not permitted for acts, omissions or transactions from which
a director of a California corporation may not be relieved of personal
liability as described above and (ii) such indemnification is not permitted in
circumstances where California law expressly prohibits indemnification, as
described above. Meridian California's Articles of Incorporation permitted
indemnification beyond that expressly mandated by the California Corporations
Code and limited director monetary liability to the extent permitted by
California law. Meridian California has entered into indemnification agreements
with its officers and directors.

  Delaware law also permits a Delaware corporation to provide indemnification
in excess of that provided by statute. By contrast to California law, Delaware
law does not require authorizing provisions in the certificate of incorporation
and does not contain express prohibitions on indemnification in certain
circumstances. Limitations on indemnification may be imposed by a court,
however, based on principles of public policy.

  A provision of Delaware law states 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. Under
Delaware law, therefore, the indemnification agreements entered into by
Meridian California with its officers and directors were assumed by Meridian
Delaware upon completion of the 1997 reincorporation. The indemnification
agreements were amended to the extent necessary to conform the agreements to
Delaware law. In particular, the indemnification agreements were amended to
include within their purview future changes in Delaware law that expand the
permissible scope of indemnification of directors and officers of Delaware
corporations.

  Inspection of Shareholder List. Both California and Delaware law allow any
shareholder to inspect the shareholder list for a purpose reasonably related to
such person's interests as a shareholder. California law provides, in addition,
for an absolute right to inspect and copy the corporation's shareholder list by
persons holding an aggregate of five percent (5%) or more of a corporation's
voting shares, or shareholders holding an aggregate of one percent (1%) or more
of such shares who have filed a Schedule 14A under the revised proxy rules.
Under California law, such absolute inspection rights also apply to a
corporation formed under the laws of any other state if its principal executive
offices are in California or if it customarily holds meetings of its board in
California. Delaware law contains no provisions comparable to the absolute
right of inspection provided by California law to certain shareholders.

  Dividends and Repurchases of Shares. California 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.

  Under California law, a corporation may not make any distribution (including
dividends, whether in cash or other property, and repurchase of its shares,
other than repurchase of its shares issued under employee stock

                                       64
<PAGE>

plans contemplated by Section 408 of the California Corporations Code) unless
either (i) the corporation's retained earnings immediately prior to the
proposed distribution equal or exceed the amount of the proposed distribution
or (ii) immediately after giving effect to such distribution, the corporation's
assets (exclusive of goodwill, capitalized research and development expenses
and deferred charges) would be at least equal to 1 1/4 times its liabilities
(not including deferred taxes, deferred income and other deferred credits), and
the corporation's current assets would be at least equal to its current
liabilities (or 1 1/4 times its current liabilities if the average pre-tax and
pre-interest expense earnings for the preceding two fiscal years were less than
the average interest expense for such years). Such tests are applied to
California corporations on a consolidated basis.

  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 the
capital of the corporation is not impaired and such redemption or repurchase
would not impair the capital of the corporation.

  To date, Meridian has not paid any cash dividends or repurchased any of its
shares.

  Shareholder Voting. Both California and Delaware law generally require that a
majority of the shareholders of both 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 stock of the
surviving corporations outstanding immediately before the effective date of the
merger is an identical outstanding of treasury share after the merger, and (c)
either no shares of common stock of the surviving corporation and no shares,
securities or obligations convertible into such stock are to be issued or
delivered under the plan of merger, or the authorized unissued shares or the
treasury shares of common stock of the surviving corporation to be issued or
delivered under the plan of merger plus those initially issuable upon
conversion of any other shares, securities or obligations to be issued or
delivered under such plan do not exceed twenty percent (20%) of the shares of
common stock of such constituent corporation outstanding immediately prior to
the effective date of the merger. California law contains a similar exception
to its voting requirements for reorganizations where shareholders of the
corporation itself, or both, immediately prior to the reorganization will own
immediately after the reorganization equity securities constituting more than
five sixths of the voting power of the surviving or acquiring corporation or
its parent entity.

  Both California law and Delaware law also require that a sale of all or
substantially all of the assets of a corporation be approved by a majority of
the outstanding voting shares of the corporation transferring such assets.

  With certain exceptions, California law also requires that mergers,
reorganizations, certain sales of assets, and similar transactions be approved
by a majority vote of each class of shares outstanding. In contrast, Delaware
law generally does not require class voting, except in certain transactions
involving an amendment to the certificate of incorporation that adversely
affects a specific class of shares. As a result, shareholder approval of such
transactions may be easier to obtain under Delaware law for companies which
have more than one class of shares outstanding.

  California law also requires that holders of nonredeemable common stock
receive nonredeemable common stock in a merger of the corporation with the
holder of more than fifty percent (50%) but less than ninety percent (90%) of
such common stock or its affiliate unless all of the holders of such common
stock consent to the transaction. This provision of California law may have the
effect of making a "cash-out" merger by a majority shareholder more difficult
to accomplish. Although Delaware law does not parallel California law in

                                       65
<PAGE>

this respect, under some circumstances Section 203 does provide similar
protection against coercive two-tiered bids for a corporation in which the
stockholders are not treated equally. See "Significant Differences Between the
Corporation Laws of California and Delaware--Stockholder Approval of Certain
Business Combinations."

  California law provides that except in certain circumstances when a tender
offer or a proposal for a reorganization or for a sale of assets is made by an
interested party (generally a controlling or managing person of the target
corporation), an affirmative opinion in writing as to the fairness of the
consideration to be paid to the shareholders must be delivered to shareholders.
This fairness opinion requirement does not apply to a corporation that does not
have shares held of record by at least 100 persons, or to a transaction that
has been qualified under California state securities laws. Furthermore, if a
tender of shares or vote is sought pursuant to an interested party's proposal
and a later proposal is made by another party at least ten days prior to the
date of acceptance of the interested party proposal, the shareholders must be
informed of the later offer and be afforded a reasonable opportunity to
withdraw any vote, consent or proxy, or to withdraw any tendered shares.
Delaware law has no comparable provision.

  Interested Director Transactions. Under both California 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 California and Delaware
law. Under California and Delaware law, (a) either the shareholders or 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 "just and reasonable" (in California) or
"fair" (in Delaware) to the corporation, or (b) the contract or transaction
must have been just and reasonable or fair as to the corporation at the time it
was approved. In the latter case, California law explicitly places the burden
of proof on the interested director. Under California law, if shareholder
approval is sought, the interested director is not entitled to vote his shares
at a shareholder meeting with respect to any action regarding such contract or
transaction. 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). Therefore, certain transactions
that the board of directors of Meridian California might not have been able to
approve because of the number of interested directors, could be approved by a
majority of the disinterested directors of Meridian Delaware, although less
than a majority of a quorum. Meridian has not proposed, and is not aware of any
plans to propose, any transaction involving directors of Meridian that could
not be so approved under California law but could be so approved under Delaware
law.

  Shareholder Derivative Suits. California law provides that a shareholder
bringing a derivative action on behalf of a corporation need not have been a
shareholder at the time of the transaction in question, provided that certain
tests are met. Under Delaware law, a stockholder may bring a derivative action
on behalf of the corporation only if the stockholder was a stockholder of the
corporation at the time of the transaction in question or if his or her stock
thereafter devolved upon him or her by operation of law. California law also
provides that the corporation or the defendant in a derivative suit may make a
motion to the court for an order requiring the plaintiff shareholder to furnish
a security bond. Delaware does not have a similar bonding requirement.

  Appraisal Rights. Under both California and Delaware law, a shareholder of a
corporation participating in certain major corporate transactions may, under
varying circumstances, be entitled to appraisal rights pursuant to which such
shareholder 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 fair market value is determined
exclusive of any element of value arising from the accomplishment or
expectation of the merger or consolidation, and such appraisal 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 the shares of which are either listed on a
national securities exchange or are held of record by

                                       66
<PAGE>

more than 2,000 holders if such stockholders receive only shares of the
surviving corporation or shares of any other corporation that 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 of such corporations, 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 under certain
provisions of Delaware law.

  The limitations on the availability of appraisal rights under California law
are different from those under Delaware law. Shareholders of a California
corporation whose shares are listed on a national securities exchange or on a
list of over-the-counter margin stocks issued by the Board of Governors of the
Federal Reserve System generally do not have such appraisal rights unless the
holders of at least five percent (5%) of the class of outstanding shares claim
the right of the corporation or any law restricts the transfer of such shares.
Appraisal rights are also unavailable if the shareholders of a corporation or
the corporation itself, or both, immediately prior to the reorganization will
own immediately after the reorganization equity securities constituting more
than five-sixths of the voting power of the surviving or acquiring corporation
or its parent entity (as will be the case in the 1997 reincorporation).
Appraisal or dissenters' rights were, therefore, not available to shareholders
of Meridian California with respect to the 1997 reincorporation. California law
generally affords appraisal rights in sale or asset reorganizations.

  Dissolution. Under California law, shareholders holding fifty percent (50%)
or more of the total voting power may authorize a corporation's dissolution,
with or without the approval of the corporation's board of directors, and this
right may not be modified by the articles of incorporation. Under Delaware law,
unless the board of directors approves the proposal to dissolve, the
dissolution must be approved by all the stockholders entitled to vote thereon.
Only if the dissolution is initially approved by the board of directors may it
be approved by a simple majority of the outstanding shares of the corporation's
stock entitled to vote. In the event of such a board-initiated dissolution,
Delaware law allows a Delaware corporation to include in its certificate of
incorporation a supermajority (greater than a simple majority) voting
requirement in connection with dissolutions. Meridian Delaware's Certificate of
Incorporation contains no such supermajority requirement, however, and a
majority of the outstanding shares entitled to vote, voting at a meeting at
which a quorum is present, would be sufficient to approve a dissolution of
Meridian Delaware that had previously been approved-by its board.

Required Vote; Recommendation Of The Meridian Board

  Ratification of the 1997 reincorporation, which will also constitute approval
of:

  .  the reincorporation merger agreement effecting the reincorporation
     merger, the Certificate of Incorporation and the bylaws of Meridian
     Delaware,

  .  the assumption of Meridian California's employee benefit plans and
     outstanding stock options by Meridian Delaware,

  .  revisions in Meridian's indemnification agreements with its officers and
     directors to conform those agreements to Delaware law, and

  .  all other acts and things done by Meridian and its officers and
     directors in furtherance of the 1997 ratification, including all acts
     and things done by Meridian and its officers and directors in other good
     faith reliance on their belief that the 1997 reincorporation had been
     properly approved by the requisite shareholder vote, will require the
     affirmative vote of the holders of a majority of all shares outstanding
     and entitled to vote on this proposal.

  The Meridian board unanimously recommends a vote "for" the ratification of
the 1997 reincorporation. The effect of an abstention is the same as that of a
vote against the ratification of the 1997 reincorporation.

  The approval of the ratification of the 1997 reincorporation is a condition
precedent to the closing of the merger with Quantum. A vote against the
ratification of the 1997 reincorporation will have the same effect as a vote
against the merger.

                        THE DLT & STORAGE SYSTEMS GROUP

   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
                                   OPERATIONS

You should read this discussion along with the DLT & Storage Systems group's
combined financial statements contained in this proxy statement. Historical
results and percentage relationships may not necessarily be indicative of
operating results for any future periods.
Overview

The DLT & Storage Systems group derives its revenue from the following sources:

  . DLTtape Drives. The DLT & Storage Systems group has generally experienced
    increasing sales and attractive gross margins for its DLTtape drives due
    to increasing acceptance of DLTtape drives as the de facto industry
    standard in the mid-range network server market. During fiscal years 1997
    through 1999, the number of mid-range network servers with tape storage
    back-up capability increased significantly with the growth of mission
    critical server-based computing, and the DLT & Storage Systems group
    expects this trend to continue.

  . DLTtape Media Cartridges and Royalty. The DLT & Storage Systems group
    derives a substantial portion of its revenue from direct sales of DLTtape
    media cartridges and royalties received from licensed DLTtape media
    cartridge providers. As the installed base of DLTtape drives increases,
    additional DLTtape media cartridges are consumed resulting in continuing
    purchases during the productive life of the DLTtape drive. DLTtape media
    cartridges are manufactured for the DLT & Storage Systems group primarily
    by Fuji and Maxell. These media cartridge manufacturers are first
    required to satisfy all of the DLT & Storage Systems group's media
    cartridge requirements, after which time they are permitted to sell to
    third parties in exchange for a royalty fee payable to the DLT & Storage
    Systems group.

   Prior to fiscal year 1999, almost all DLTtape media cartridges were sold
   directly by the DLT & Storage Systems group. However, during fiscal year
   1999, increased DLTtape media cartridge availability allowed the media
   cartridge manufacturers to sell DLTtape media cartridges, for which the
   DLT & Storage Systems group receives royalties. The DLT & Storage Systems
   group estimates that in fiscal year 1999, sales by the media cartridge
   manufacturers accounted for approximately two-thirds of total DLTtape
   media cartridge sales, and the DLT & Storage Systems group accounted for
   the balance. This compares to fiscal year 1998 sales by the media
   cartridge manufacturers of approximately one-quarter of total DLTtape
   media cartridge sales. Royalty receipts by the DLT & Storage Systems
   group are reported as royalty revenue, which is significantly lower than
   the equivalent DLTtape media cartridge revenue for the DLT & Storage
   Systems group. However, this royalty model has generated income from
   operations comparable to that generated by DLTtape media cartridge sales
   made directly by the DLT & Storage Systems group.

  . Storage Systems. Storage systems revenue includes both tape libraries and
    services and solid state storage systems. The acquisition of ATL in
    September 1998 combined ATL's mid-range to high-end tape library product
    line and services with the DLT & Storage Systems group's autoloader
    products, thereby increasing sales in the storage systems category. Sales
    of solid state storage systems have been declining in large part due to
    falling dynamic random access memory prices, which have translated into
    lower unit prices for these products, and a slight decline in unit
    volume.

*  Represents intra-group sales of DLTtape drives for incorporation into the
   DLT & Storage Systems group's tape libraries.
** Based on reports received from the media cartridge manufacturers, the DLT &
   Storage Systems group estimates that if it had sold directly all DLTtape
   media cartridges sold by the media cartridge manufacturers and, accordingly,
   not collected any royalty revenue, its total revenue would have increased by
   $65 million and $301 million in fiscal years 1998 and 1999, respectively.
   This shift in revenue did not have any significant effect on the DLT &
   Storage Systems group's operating income.

Fluctuating Quarterly Revenue

The discussion below describes the principal factors resulting in fluctuation
of the DLT & Storage Systems group's quarterly revenue for fiscal years 1997,
1998 and 1999.

  . DLTtape Drive Inventory Correction. During fiscal year 1997 and the first
    quarter of fiscal year 1998, the DLT & Storage Systems group's supply of
    DLTtape drives was not sufficient to meet demand. As a result, in the
    first half of fiscal year 1998 a few large customers began building up
    larger inventories of DLTtape drives than were required for their normal
    operations. As the DLT & Storage Systems group's manufacturing capacity
    increased and the DLT & Storage Systems group was able to meet customer
    demand for DLTtape drives, these customers reduced their orders to lower
    inventories to more typical levels. These actions resulted in reduced
    sales of DLTtape drives beginning in the third quarter of fiscal year
    1998 and more significantly in the fourth quarter of fiscal year 1998 and
    the first quarter of fiscal year 1999.

  . Shift in DLTtape Media Cartridge Revenue to Royalty Revenue. From the
    third quarter of fiscal year 1998 to the fourth quarter of fiscal year
    1999, DLTtape media cartridge revenue decreased from $65 million to $41
    million as an increasing percentage of DLTtape media sales were made by
    the media cartridge manufacturers. During this same period, the DLT &
    Storage Systems group's royalty revenue from sales of DLTtape media
    cartridges grew from under $10 million to over $30 million. The royalty
    revenue approximates the income from operations that the DLT & Storage
    Systems group would have earned had the DLTtape media cartridges been
    directly sold by the DLT & Storage Systems group.

  . ATL Acquisition. The DLT & Storage Systems group completed the ATL
    acquisition at the beginning of the third quarter of fiscal year 1999.
    This increased DLTtape library and service revenue in this quarter as the
    acquisition combined ATL's mid-range to high-end DLTtape library revenue
    with the DLT & Storage Systems group's entry-level DLTtape library
    revenue.

Results of Operations

 Fiscal Year 1999 Compared With Fiscal Year 1998
   Revenue. Total the DLT & Storage Systems group revenue in fiscal year 1999
was $1.3 billion, compared to $1.2 billion in fiscal year 1998, an increase of
9%. The increase in revenue reflected increases in DLTtape drive revenue and
total DLTtape media cartridge revenue, and combining ATL's revenue effective
September 28, 1998. The increase in DLTtape drive revenue reflected strong
demand in the second half of fiscal year 1999. Including sales by licensed
media cartridge manufacturers, total DLTtape media cartridge revenue increased.
However, direct DLTtape media cartridge sales by the DLT & Storage Systems
group declined reflecting the shift in a substantial portion of DLTtape media
cartridge revenue from sales by the DLT & Storage Systems group to royalties
from the media cartridge manufacturers.

Sales to the DLT & Storage Systems group's top five customers in fiscal year
1999 represented 53% of revenue, compared to 63% of revenue in fiscal year
1998. These amounts reflected a retroactive combination of the sales to Compaq
and Digital Equipment as a result of their merger in June 1998. Sales to Compaq
were 25% of revenue in fiscal year 1999, compared to 36% of revenue in fiscal
year 1998, including sales made to Digital Equipment. Sales to Hewlett-Packard
were 13% of revenue in fiscal year 1999, compared to 11% of revenue in fiscal
year 1998.

   In fiscal year 1999, sales to computer equipment manufacturers and
distribution channel customers were 71% and 17% of revenue, respectively,
compared to 79% and 21% of revenue, respectively, in fiscal year 1998. The
remaining revenue in fiscal year 1999 represented media royalty revenue and
sales to value-added resellers.

   Gross Margin Rate. The gross margin rate in fiscal year 1999 was 44.5%,
compared to 42.2% in fiscal year 1998. The 2.3 percentage point increase
reflected an increase in the proportion of overall revenue represented by
royalty revenue. Declines in the gross margin rate earned on DLTtape drives
resulting from price reductions aimed at expanding the overall market for
DLTtape drives partially offset the increase from royalty revenue.

   Research and Development Expenses.  Research and development expenses in
fiscal year 1999 were $99 million, or 7.6% of revenue, compared to $63 million,
or 5.3% of revenue, in fiscal year 1998. The increase in research and
development expenses reflected higher research and development expenses related
to new tape drive products and to other new information storage products and
technologies, including Super DLTtape technology and, to a significantly lesser
extent, optical storage technology and combining ATL's expenses.

   Sales and Marketing Expenses. Sales and marketing expenses in fiscal year
1999 were $77 million, or 5.9% of revenue, compared to $47 million, or 4.0% of
revenue in fiscal year 1998. This reflected the combining of ATL's expenses and
an increase in marketing and advertising costs associated with DLTtape
products.

   General and Administrative Expenses.  General and administrative expenses in
fiscal year 1999 were $38 million, or 2.9% of revenue, compared to $22 million,
or 1.9% of revenue, in fiscal year 1998. The increase in general and
administrative expenses reflected expansion of the DLT & Storage Systems
group's infrastructure to support increased revenue and earnings growth and the
combining of ATL's expenses.

   Purchased In-process Research and Development Expense. The DLT & Storage
Systems group expensed purchased in-process research and development costs of
$89 million as a

                                       70
<PAGE>

result of the ATL acquisition in fiscal year 1999. For additional information
regarding the ATL acquisition and the costs associated with in-process research
and development, see Note 5 of the Notes to Combined Financial Statements.

   Interest and Other Income/Expense. Net interest and other income and expense
in fiscal year 1999 was $12 million expense, compared to $3 million expense in
fiscal year 1998. The increase reflected a $6.8 million write-down of an equity
investment. In addition, the increase reflected a reduction in interest income
as cash was used to purchase treasury stock prior to the ATL acquisition. A
reduction in interest expense partially offset this increase.

   Income Taxes. The DLT & Storage Systems group's effective tax rate in fiscal
year 1999, excluding the write-off of the purchased in-process research and
development, was 40%, compared to 39% in fiscal year 1998. The DLT & Storage
Systems group recorded a provision for income taxes at an effective rate of
53.5% of pretax earnings in fiscal year 1999. This higher effective tax rate
was primarily attributable to the impact of the purchased in-process research
and development write-off, for which a tax benefit is not recognizable, and a
lower research and development credit.

   Net Income. The DLT & Storage Systems group reported net income in fiscal
year 1999 of $123 million, compared to $224 million in fiscal year 1998. The
decrease primarily resulted from the charge for purchased in-process research
and development of $89 million. Excluding the charge, net income was $212
million, a decrease of $12 million. This decrease reflected increased
amortization of goodwill and other intangible assets resulting from the ATL
acquisition, increased operating expenses and decreased interest income. This
decrease was partially offset by an increase in gross profit.

 Fiscal Year 1998 Compared With Fiscal Year 1997

   Revenue. Total revenue in fiscal year 1998 was $1.2 billion, compared to
$728 million in fiscal year 1997, an increase of 63%. The increase in total
revenue resulted from an increase in DLTtape drive and DLTtape media cartridges
product shipments. The increase in total revenue reflected growth in market
acceptance of DLTtape technology and a shift in sales mix to higher storage
capacity products which carry a higher per unit price. However, the average
price at each storage capacity level of DLTtape drives and DLTtape media
cartridge products declined when compared with fiscal year 1997.

   The increase in DLTtape drive shipments reflected, in part, an increase in
tape drive production volume, which was at a level high enough to meet product
demand beginning in the third quarter of fiscal year 1998. However, the general
availability of DLTtape drives resulted in sequentially lower DLTtape drive
sales in the fourth quarter of fiscal year 1998 as certain computer equipment
manufacturer customers reduced purchases in order to adjust their inventory
levels.

   Sales to the DLT & Storage Systems group's top five customers were 63% of
revenue in fiscal years 1998 and 1997. This amount reflects a retroactive
combination of the sales to Compaq and Digital Equipment. Sales to Compaq were
36% of revenue in fiscal year 1998, compared to 35% of revenue in fiscal year
1997, including sales to Digital Equipment. Sales to Hewlett Packard were 11%
of revenue in fiscal year 1998, compared to 14% of revenue in fiscal year 1997.

   Sales to computer equipment manufacturers and distribution channel customers
were 79% and 21% of revenue, respectively, in fiscal year 1998, compared to 77%
and 23% of revenue, respectively, in fiscal year 1997.

   Gross Margin Rate. The gross margin rate was 42.2% in fiscal year 1998,
compared to 37.1% in fiscal year 1997. The 5.1 percentage point increase
reflected an increase in the gross margin rate earned on DLTtape drives and
DLTtape media cartridges as sales shifted to the higher margin DLT7000.

   Research and Development Expenses.  Research and development expenses in
fiscal year 1998 were $63 million, or 5.3% of revenue, compared with $30
million, or 4.1% of revenue, in fiscal year 1997. The $33 million increase in
research and development expenses reflected higher expenses related to new
information storage products and technologies, including Super DLTtape
technology and, to a significantly lesser extent, optical storage technology.

                                       71
<PAGE>

   Sales and Marketing Expenses. Sales and marketing expenses in fiscal year
1998 were $47 million, or 4.0% of revenue, compared with $24 million, or 3.3%
of revenue, in fiscal year 1997. This increase primarily reflected the
increased costs associated with supporting the DLT & Storage Systems group's
higher sales volume.

General and Administrative Expenses. General and administrative expenses in
fiscal year 1998 were $22 million, or 1.9% of revenue, compared with $11
million, or 1.6% of revenue, in fiscal year 1997. The increase in general and
administrative expenses reflected expansion of the DLT & Storage Systems
group's infrastructure to support increased shipments and revenue growth.

Interest and Other Income/Expense. Net interest and other income and expense in
fiscal year 1998 was $3 million expense, compared with $26 million expense in
fiscal year 1997. A decrease in interest expense reflecting a year-over-year
decrease in the average level of debt used to finance operations, and an
increase in year-over-year average level of cash, combined to cause this
change.

Income Taxes. The DLT & Storage Systems group's effective tax rate was 39% and
40% for fiscal years 1998 and 1997, respectively. The decrease in the tax rate
for fiscal year 1998 was primarily attributable to a research and development
credit.

Net Income. The DLT & Storage Systems group reported net income in fiscal year
1998 of $224 million, compared to $108 million in fiscal year 1997. The
increase reflected increased total revenue and gross profit, partially offset
by an increase in operating expenses and a reduction in interest income.

Our quarterly and annual operating results have fluctuated in the past and are
likely to fluctuate significantly in the future due to a variety of factors,
many of which are outside of our control. Because of these and other factors,
our quarterly revenue, expenses and results of operations could vary
significantly in the future, and period-to-period comparisons should not be
relied upon as indications of future performance. We may not be able to
increase our revenue in future periods or be able to sustain our existing level
of revenue or our rate of revenue growth on a quarterly or annual basis. In
addition, our annual or quarterly operating results may not meet the
expectations of securities analysts and investors. If this happens, the trading
price of our common stock could significantly decline.

Recent Accounting Pronouncements

In June 1997, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 130, "Reporting
Comprehensive Income," which the DLT & Storage Systems group implemented in
fiscal year 1999. SFAS No. 130 establishes standards for reporting and display
of comprehensive income and its components--revenue, expenses, gains, and
losses--in a full set of general-purpose financial statements. The adoption of
SFAS No. 130 changed financial statement presentation but did not have an
impact on the DLT & Storage Systems group's financial position or results of
operations.

In June 1997, the FASB issued SFAS No. 131, "Disclosure about Segments of an
Enterprise and Related Information," requires certain financial and descriptive
information about a company's reportable operating segments. The DLT & Storage
Systems group adopted SFAS No. 131 in fiscal year 1999. The adoption of SFAS
No. 131 applies solely to disclosure and will not have an impact on the DLT &
Storage Systems group's financial position or results of operations.

Liquidity and Capital Resources

Operating Activities. The DLT & Storage Systems group generated cash from
operations of $217 million during fiscal year 1999. The DLT & Storage Systems
group's cash provided by operations in fiscal year 1998 was $203 million.

Investing Activities. Investments during fiscal year 1999 were $35 million,
which consisted primarily of investments in property and equipment. Investments
in fiscal year 1998 totaled $62 million.

Financing Activities. At March 31, 1999, and March 31, 1998, Quantum's debt
allocated to the DLT & Storage Systems group was $230 million and $219 million,
respectively. Debt allocated to the DLT & Storage Systems group bears interest
at a rate equal to the weighted average interest rate of Quantum's total debt,
calculated on a quarterly basis. At March 31, 1999, Quantum had total debt of
$345 million with an average interest rate of 7.3%. In the future, each group's
debt will increase or decrease by the amount of any cash provided by or used
for the group's operating activities, investing activities, share repurchases
or issuances and other non-debt-related financing activities. See Note 1 to
Combined Financial Statements for further discussion of financing activities.

In December 1998, ATL entered into a senior credit facility that provides a $35
million revolving credit line to ATL. The revolving credit line is co-terminous
with Quantum's $500 million revolving credit line, expiring in June 2000. At
the option of ATL, borrowings under the revolving credit line bear interest at
either London interbank offered rate plus a margin determined by Quantum's
total funded debt ratio, or at a base rate, with option periods of one to six
months. At March 31, 1999, $18 million was outstanding on this revolving credit
line.

Quantum filed a registration statement which became effective on July 24, 1997,
pursuant to which Quantum may issue debt or equity securities, in one or more
series or issuances, limited to $450 million aggregate public offering price.
Under the registration statement, in July 1997, Quantum issued $288 million of
7% convertible subordinated notes. The notes mature on August 1, 2004, and are
convertible at the option of the holder at any time prior to maturity, unless
previously redeemed, into shares of Quantum's common stock at a conversion
price of $46.325 per share. Quantum has the option to redeem the notes on or
after August 1, 1999 and prior to August 1, 2001, under certain conditions
related to the price of Quantum's common stock. Subsequent to August 1, 2001,
Quantum may redeem the notes at any time. In the event of certain changes
involving all or substantially all of Quantum's common stock, the holder would
have the option to redeem the notes. Redemption prices range from 107% of the
principal to 100% at maturity. The notes are unsecured obligations

                                       74
<PAGE>

subordinated in right of payment to all of Quantum's existing and future senior
indebtedness.

   Each of the 7% convertible subordinated notes, is convertible into shares of
the DLT & Storage Systems group stock and shares of Hard Disk Drive group
stock. The number of shares of the DLT & Storage Systems group stock and Hard
Disk Drive group stock into which each note is convertible is equal to the
numbers of shares which the holder of the note would have received under the
tracking stock proposal had such note been converted immediately prior to the
implementation of the tracking stock. The notes are not separately convertible
into solely the DLT & Storage Systems group stock or solely Hard Disk Drive
group stock. The exercise price and maturity date of each convertible note was
not be affected by the implementation of the tracking stock.

In June 1997, Quantum entered into an unsecured senior credit facility that
provides a $500 million revolving credit line and expires in June 2000. At
Quantum's option, borrowings under the revolving credit line bear interest at
either London interbank offered rate plus a margin determined by our total
funded debt ratio, or at a base rate, with option periods of one to six months.
At March 31, 1999, there was no outstanding balance drawn on this line.

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

The DLT & Storage Systems group expects to spend approximately $70 million in
fiscal year 2000 for capital equipment and leasehold improvements. These
capital expenditures will support the expansion of the DLTtape product line,
production of Super DLTtape products and DLT & Storage Systems group's general
infrastructure.

The DLT & Storage Systems group expects its cash flow from operations, together
with available financing sources, will be sufficient to meet all currently
planned expenditures and sustain operations for the next 12 months. However,
this belief assumes that operating results and cash flow from operations will
meet our expectations.

If the merger described in this proxy statement/ prospectus is approved, the
acquisition will be accounted for as a purchase, and the DLT & Storage Systems
group expects to recognize a charge for purchased in-process research and
development upon closing of the acquisition.

Meridian had revenue of $4 million and $18 million in the quarter ended March
31, 1999, and the year ended December 31, 1998, respectively. At March 31,
1999, Meridian had total cash and marketable securities of $15 million. At
December 31, 1998, Meridian had a net operating loss carryforward for U.S.
federal income tax purposes of approximately $32 million.

The Hard Disk Drive group experienced the following key trends in its desktop
and high-end hard disk drive products during the fiscal years 1997 through
1999:

  . Desktop Hard Disk Drives. Because desktop hard disk drives are the key
    storage device within PCs, the PC market generates demand for desktop
    hard disk drives. The growth and pervasive use of PCs in both the
    business and home have generally resulted in increasing sales of the Hard
    Disk Drive group's desktop hard disk drives. However, a market demand
    slowdown, coupled with inventory curtailment by leading computer
    equipment manufacturers, negatively affected revenue during the five most
    recent quarters. In addition, intense competition in the market for both
    PCs and desktop hard disk drives has resulted in generally declining hard
    disk drive prices despite increases in the capacity and performance of
    hard disk drives.

  . High-end Hard Disk Drives. High-end hard disk drives are predominately
    used in servers, workstations and storage sub-systems. Although the
    market for high-end hard disk drives has continued to expand, IBM and
    Seagate have held the largest market share in these markets. The Hard
    Disk Drive group has experienced difficulty in gaining market share and
    has experienced continuing losses in this business. The Hard Disk Drive
    group, however, recognizes the long term potential of this market, and
    has continued its strategy of focusing on the fast growing network server
    and workstation market and has taken several important steps in an effort
    to improve its performance. The Hard Disk Drive group transitioned all of
    its high-end manufacturing to Matsushita-Kotobuki beginning in the fourth
    quarter of fiscal year 1996, which was substantially completed by the
    second quarter of fiscal year 1997. This transition has contributed to a
    recent improvement in the reliability of the Hard Disk Drive group's new
    high-end products. The Hard Disk Drive group has also recently improved
    its time-to-market performance and now has a complete high-end product
    offering with both 7200 RPM and 10,000 RPM products with SCSI and fibre
    channel interfaces, both of which are high speed interfaces used in the
    enterprise storage market.

Results of Operations

 Fiscal Year 1999 Compared With Fiscal Year 1998

Revenue. Revenue in fiscal year 1999 was $3.6 billion, compared to $4.6 billion
in fiscal year 1998, a decrease of 22%. The decrease in revenue reflected lower
revenue from sales of both desktop and high-end hard disk drives.

  . Desktop hard disk drive revenue in fiscal year 1999 was $3.1 billion,
    compared to $4.0 billion in fiscal year 1998. The decline in desktop hard
    disk drive revenue reflected a decline in average unit prices and, to a
    lesser extent, a lower level of shipments to leading computer equipment
    manufacturers. The price decline reflected intense competition,
    especially in the first two quarters of fiscal year 1999, and the growth
    of the low cost PC market, which has become a higher proportion of the
    overall desktop PC market.

  . High-end hard disk drive revenue in fiscal year 1999 was $520 million,
    compared to $634 million in fiscal year 1998. Although high-end hard disk
    drive shipments increased in fiscal year 1999, increased competitive
    pricing pressures, especially in the second half of fiscal year 1999,
    resulted in reduced average unit prices and lower high-end hard disk
    drive revenue.

   Sales to the top five customers in fiscal year 1999 represented 43% of
revenue, compared to 44% of revenue in fiscal year 1998. These amounts
reflected a retroactive combination of the sales to Compaq and Digital
Equipment as a result of their merger in June 1998. Sales to Compaq were 10% of
revenue in fiscal year 1999, compared to 12% of revenue in fiscal year 1998,
including sales to Digital Equipment. Sales to Hewlett-Packard were 14% of
revenue in both fiscal years 1999 and 1998.

   In fiscal year 1999, sales to computer equipment manufacturers and
distribution channel customers were 60% and 40% of revenue, respectively,
compared to 59% and 41% of revenue, respectively, in fiscal year 1998.

Gross Margin Rate. The gross margin rate in fiscal years 1999 and 1998 was
8.1%.

  . The desktop gross margin rate in fiscal year 1999 was 7.5%, compared to
    11.4% in fiscal year 1998.

  . The high-end gross margin rate in fiscal year 1999 was 11.4%, compared to
    -12.7% in fiscal year 1998.

The gross margin rate in fiscal year 1998 reflected the impact of a $103
million special charge related to the transition to a new generation of high-
end disk drive products, and consisted primarily of inventory write-offs and
adjustments, and losses related to firm inventory purchase commitments.
Excluding the special charge, the gross margin rate was 10.3% in fiscal year
1998. This 2.2 percentage point decline between fiscal year 1998 and 1999
reflected the decline in gross margins earned on desktop hard disk drives as a
result of intense competitive pricing pressures in fiscal year 1999.

Research and Development Expenses.  Research and development expenses in fiscal
year 1999, were $254 million, or 7.1% of revenue, compared to $259 million, or
5.6% of revenue, in fiscal year 1998. The decrease in research and development
expenses reflected reduced spending as a result of cost control efforts.

Sales and Marketing Expenses. Sales and marketing expenses in fiscal year 1999,
were $114 million, or 3.2% of revenue, compared to $122 million, or 2.6% of
revenue in fiscal year 1998. The decrease in sales and marketing expenses
reflected reduced spending including lower commissions as a result of the lower
level of revenue.

General and Administrative Expenses.  General and administrative expenses in
fiscal year 1999, were $56 million, or 1.5% of revenue, compared to $67
million, or 1.5% of revenue, in fiscal year 1998. The decrease in general and
administrative expenses reflected the impact of cost control efforts.

Interest and Other Income/Expense. Net interest and other income and expense in
fiscal year 1999 was $10 million income, compared to $5 million income in
fiscal year 1998. The increase reflected increased interest income on higher
cash balances and reduced interest expense.

<PAGE>

   Loss from Investee. The Hard Disk Drive group's investment and operating
results related to its recording heads business have resulted in significant
losses. The Hard Disk Drive group acquired a recording heads business from
Digital Equipment in October 1994. In May 1997, The Hard Disk Drive group sold
a 51% majority interest in its recording heads operations to Matsushita-
Kotobuki, and formed a recording heads joint venture with Matsushita-Kotobuki.
On October 28, 1998, the Hard Disk Drive group and Matsushita-Kotobuki agreed
to dissolve the recording heads joint venture. In connection with
the dissolution, the Hard Disk Drive group recorded a $101 million loss in the
third quarter of fiscal year 1999. This loss included a write-off of the
Hard Disk Drive group's investment in the recording heads joint venture; a
write-down of the Hard Disk Drive group's interest in facilities in Louisville,
Colorado, and Shrewsbury, Massachusetts that were occupied by the recording
heads joint venture; warranty costs resulting from magneto resistive recording
heads manufactured by the recording heads joint venture; and the Hard Disk
Drive group's 49% pro rata share in funding the recording heads joint venture's
repayment of its obligations, primarily bank debt, accounts payable and other
liabilities. See Note 5 of the Notes to Combined Financial Statements for
additional discussion of the dissolution of the recording heads joint venture.

   Income Taxes. The Hard Disk Drive group recorded benefits of $112 million
and $83 million for effective benefit rates of 42% and 61% in fiscal years 1999
and 1998, respectively. The 1999 effective rate reflects decreased benefits
from foreign earnings taxed at less than the U.S. rate, a lower research and
development credit and decreased state tax benefits. Fiscal year 1998 includes
a benefit as a result of the recognition of state deferred tax assets through
tax planning.

   Net Loss. The Hard Disk Drive group reported a net loss in fiscal year 1999
of $153 million, compared to $53 million in fiscal year 1998. The increased
loss resulted from the $101 million charge related to the recording heads joint
venture dissolution and the decrease in revenue and gross profit, partially
offset by a decrease in operating costs.

 Fiscal Year 1998 Compared With Fiscal Year 1997

Revenue. Revenue in both fiscal years 1998 and 1997 was $4.6 billion.

  . Desktop hard disk drive revenue in both fiscal years 1998 and 1997 was
    $4.0 billion.

  . High-end hard disk drive revenue for fiscal year 1998 was $634 million,
    compared to $587 million in fiscal year 1997.

   Declines in average unit prices for both desktop and high-end disk drives
substantially offset an increase in disk drive unit shipments. Oversupply and
intensely competitive pricing in these markets, particularly in the second half
of fiscal year 1998 and more significantly for the high-end disk drive
products, caused such declines.

   Sales to the Hard Disk Drive group's top five customers were 44% of revenue
in fiscal year 1998, compared to 40% of revenue in fiscal year 1997. These
amounts reflect a retroactive combination of the sales to Compaq and Digital
Equipment as a result of their merger in June 1998. Sales to Hewlett-Packard
were 14% of revenue in fiscal year 1998, compared with less than 10% of revenue
in fiscal year 1997. Sales to Compaq were 12% of revenue in both fiscal years
1998 and 1997, including sales to Digital Equipment.

   Sales to computer equipment manufacturers and distribution channel customers
were 59% and 41% of revenue, respectively, for fiscal year 1998 compared with
61% and 39% of revenue, respectively, in fiscal year 1997.

Gross Margin Rate. The gross margin rate decreased 2.8 percentage points to
8.1% in fiscal year 1998, from 10.9% in fiscal year 1997.

  . The desktop gross margin rate for fiscal year 1998 was 11.4%, compared to
    14.1% for fiscal year 1997.

  . The high-end gross margin rate for fiscal year 1998 was -12.7%, compared
    to -1.8% for fiscal year 1997.

The overall gross margin decrease reflected the price declines earned on
desktop and high-end hard disk drives, particularly in the second half of
fiscal year 1998, and the $103 million special charge in the

                                       78
<PAGE>

third quarter of fiscal year 1998. The special charge related to the transition
to a new generation of high-end disk drive products, and consisted primarily of
inventory write-offs and adjustments, and losses related to firm inventory
purchase commitments. Excluding the special charge, the gross margin rate was
10.3% in fiscal year 1998. The erosion of gross margins earned on hard disk
drives and the special charge both reflected the oversupply and intensely
competitive pricing in the desktop and high-end disk drive markets,
particularly in the second half of fiscal year 1998.

   Research and Development Expenses. In fiscal year 1998, research and
development expenses were $259 million, or 5.6% of revenue, compared with $261
million, or 5.7% of revenue, in fiscal year 1997.

   Sales and Marketing Expenses. Sales and marketing expenses in fiscal year
1998 were $122 million, or 2.6% of revenue, compared with $126 million, or 2.7%
of revenue, in fiscal year 1997.

   General and Administrative Expenses. General and administrative expenses in
fiscal year 1998 were $67 million, or 1.5% of revenue, compared with $75
million, or 1.6% of revenue, in fiscal year 1997.

   Interest and Other Income/Expense. Net interest and other income and expense
in fiscal year 1998 was $5 million income, compared with $15 million expense in
fiscal year 1997. A decrease in interest expense, reflecting a year-over-year
decrease in the average level of debt used to finance operations, and an
increase in the year-over-year average level of cash, combined to cause this
change.

   Loss from Investee. The loss from investee reflected the Hard Disk Drive
group's equity share in the operating losses of the recording heads joint
venture since May 16, 1997, when this joint venture was formed. Prior to
May 16, 1997, the Hard Disk Drive group fully combined its recording heads
operations. The Hard Disk Drive group's total losses from recording heads
operations for fiscal year 1998 was $75 million, compared with $110 million for
fiscal year 1997. The loss from investee for fiscal year 1998 included a charge
of approximately $5 million, which represented the Hard Disk Drive group's
share of a third quarter charge in the recording heads joint venture's
operating results for severance, equipment write-offs, lease termination and
other costs associated with the recording heads joint venture's strategic
actions. A combination of reduced unit prices, operating costs, manufacturing
yields, product transitions and soft demand for certain recording heads
products, primarily those related to high-end disk drive products, resulted in
losses by the recording heads joint venture.

Income Taxes. The Hard Disk Drive group recorded benefits of $83 million and
$19 million for fiscal years 1998 and 1997, respectively. The 1997 benefit
reflects foreign earnings taxed at less than the U.S. tax rate and valuation
allowance reversal. Fiscal year 1998 includes a benefit as a result of the
recognition of state deferred tax assets through tax planning and the benefit
of foreign earnings taxed at less than the U.S. rate.

Net Income (Loss). The Hard Disk Drive group reported a net loss in fiscal year
1998 of $53 million, compared to net income of $41 million in fiscal year 1997.
The change to a net loss resulted from the special charge related to high-end
disk drives and the erosion of margins on desktop hard disk drives. A decrease
in operating costs partially offset the decrease.

Our quarterly and annual operating results have fluctuated in the past and are
likely to fluctuate significantly in the future due to a variety of factors,
many of which are outside of our control. Because of these and other factors,
our quarterly revenue, expenses and results of operations could vary
significantly in the future, and period-to-period comparisons should not be
relied upon as indications of future performance. We may not be able to
increase our revenue in future periods or be able to sustain our existing level
of revenue or our rate of revenue growth on a quarterly or annual basis. In
addition, our annual or quarterly operating results may not meet the
expectations of securities analysts and investors. If this happens, the trading
price of our common stock could significantly decline.

Recent Accounting Pronouncements

In June 1997, the Financial Accounting Standards Board ("FASB") issued
Statement of Financial Accounting Standards ("SFAS") No. 130, "Reporting
Comprehensive Income," which the Hard Disk Drive group implemented in fiscal
year 1999. SFAS No. 130 establishes standards for reporting and display of
comprehensive income and its components--revenue, expenses, gains, and losses--
in a full set of general-purpose financial statements. The adoption of SFAS No.
130, changed financial statement presentation but did not have an impact on the
Hard Disk Drive group's financial position or results of operations.

In June 1997, the FASB issued SFAS No. 131, "Disclosure about Segments of an
Enterprise and Related Information," requires certain financial and descriptive
information about a company's reportable operating segments. The Hard Disk
Drive group adopted SFAS No. 131 in fiscal year 1999. The adoption of SFAS No.
131 applies solely to disclosure and will not have an impact on the Hard Disk
Drive group's financial position or results of operations.

Liquidity and Capital Resources

Operatings Activities. The Hard Disk Drive group generated cash from operations
of $247 million during fiscal year 1999. The Hard Disk Drive group's cash
provided by operations in fiscal year 1998 was $82 million. The increase
primarily reflects an increase in the collection of accounts receivable and a
reduction in inventories.

   Investing Activities. Investments during fiscal year 1999 were $35 million,
which consisted primarily of investments in property and equipment, partially
offset by maturities of marketable securities. Investments in fiscal year 1998
totaled $83 million.

Financing Activities. At March 31, 1999, and March 31, 1998, Quantum's debt
allocated to the Hard Disk Drive group was $115 million and $109 million,
respectively. Debt allocated to the Hard Disk Drive group bears interest at a
rate equal to the weighted average interest rate of Quantum's total debt,
calculated on a quarterly basis. At March 31, 1999, Quantum had a total debt of
$345 million with an average interest rate of 7.3%. In the future, each group's
debt will increase or decrease by the amount of any cash provided by or used
for the group's operating activities, investing activities, share repurchases
or issuances and other non-debt-related financing activities. See Note 1 to
Combined Financial Statements for further discussion of financing activities.

   In December 1998, ATL entered into a senior credit facility that provides a
$35 million revolving credit line to ATL. The revolving credit line is
co-terminous with Quantum's $500 million revolving credit line, expiring in
June 2000. At the option of ATL, borrowings under the revolving credit line
bear interest at either London interbank offered rate plus a margin determined
by Quantum's total funded debt ratio, or at a base rate, with option periods of
one to six months. At March 31, 1999, $18 million was outstanding on this
revolving credit line.

   Quantum filed a registration statement which became effective on July 24,
1997, pursuant to which Quantum may issue debt or equity securities, in one or
more series or issuances, limited to $450 million aggregate public offering
price. Under the registration statement, in July 1997, Quantum issued $288
million of 7% convertible subordinated notes. The notes mature on August 1,
2004, and are convertible at the option of the holder at any time prior to
maturity, unless previously redeemed, into shares of the Quantum's common stock
at a conversion price of $46.325 per share. Quantum has the option to redeem
the notes on or after August 1, 1999 and prior to August 1, 2001, under certain
conditions related to the price of Quantum's

                                       81
<PAGE>

common stock. Subsequent to August 1, 2001, Quantum may redeem the notes at any
time. In the event of certain changes involving all or substantially all of
Quantum's common stock, the holder would have the option to redeem the notes.
Redemption prices range from 107% of the principal to 100% at maturity. The
notes are unsecured obligations subordinated in right of payment to all of
Quantum's existing and future senior indebtedness.

   Each of the 7% convertible subordinated notes, is convertible into shares of
DLT & Storage Systems group stock and shares of Hard Disk Drive group stock.
The number of shares of Hard Disk Drive group stock and DLT & Storage Systems
group stock into which each note is convertible is equal to the number of the
shares which the holder of the note would have received had such note been
converted immediately prior to the implementation of the tracking stock. The
notes are not separately convertible into solely DLT & Storage Systems group
stock or solely Hard Disk Drive group stock. The exercise price and maturity
date of each convertible note was not be affected by the implementation of the
tracking stock.

In June 1997, Quantum entered into an unsecured senior credit facility that
provides a $500 million revolving credit line and expires in June 2000. At
Quantum's option, borrowings under the revolving credit line bear interest at
either London interbank offered rate plus a margin determined by our total
funded debt ratio, or at a base rate, with option periods of one to six months.
At March 31, 1999, there was no outstanding balance drawn on this line.

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

   The Hard Disk Drive group expects to spend approximately $85 million in
fiscal year 2000 for capital equipment and leasehold improvements. These
capital expenditures will support the expansion of the desktop and high-end
hard disk drive product lines and the introduction of hard drives for consumer
electronic applications.

   The Hard Disk Drive group expects its cash flow from operations, together
with available financing sources, will be sufficient to meet all currently
planned expenditures and sustain operations for the next 12 months. However,
this belief assumes that operating results and cash flow from operations will
meet the Hard Disk Drive group's expectations.

                     DESCRIPTION OF MERIDIAN CAPITAL STOCK

  Pursuant to its certificate of incorporation, Meridian is authorized to issue
a total of 40,000,000 shares of capital stock, consisting of 35,000,000 shares
of Meridian Common Stock, and 5,000,000 shares of preferred stock, par value
$0.01 per share.

Meridian Common Stock

  As of August 4, 1999, there were 8,599,780 outstanding shares of Meridian
Common Stock held by approximately 86 holders of record. The holders of shares
of Meridian Common Stock have one vote per share on all matters to be voted
upon by stockholders. Subject to any preferences, voting powers, qualifications
and special or relative rights or privileges of any holders of preferred stock,
holders of Meridian Common Stock are entitled, among other things, to dividends
if, when and as declared from time to time by Meridian's board of directors out
of assets legally available therefor after payment of debts and expenses. With
the exception of the rights issued pursuant to the Meridian's Preferred
Stockholders' Rights Plan, holders of shares of Meridian Common Stock have no
preemptive or other rights to subscribe for additional shares. The Meridian
Common Stock is neither redeemable nor convertible, and there are no sinking
fund provisions. Upon the voluntary or involuntary liquidation of Meridian,
holders of Meridian Common Stock are entitled to receive all remaining assets
of Meridian available for distribution to stockholders after payment to
creditors or of preference amounts owed to holders of any preferred stock.

  All of the outstanding shares of Meridian Common Stock are fully paid and
nonassessable.

Preferred Stock

  Meridian's Certificate of Incorporation authorizes the issuance of up to
5,000,000 shares of preferred stock, par value of $0.01 per share, none of
which is currently outstanding. Meridian's preferred stock may be issued from
time to time in one or more series without stockholder approval. Subject to
limitations prescribed by law, Meridian's board of directors is authorized to
determine the voting powers (if any), designation, preferences and relative,
participating, optional or other special rights, and qualifications,
limitations or restrictions thereof, for each series of preferred stock that
may be issued, and to fix the number of shares of each such series. Thus,
Meridian's board of directors, without stockholder approval, could authorize
the issuance of preferred stock with voting, conversion and other rights that
could adversely affect the voting power and other rights of holders of Meridian
Common Stock or other series of preferred stock or that could have the effect
of delaying, deferring or preventing a change in control of Meridian.

Rights Plan

  The Meridian board adopted a preferred shares rights plan (the "Rights Plan")
on July 18, 1997 that is designed to deter hostile takeover attempts, including
the accumulation of shares in the open market or through private transactions,
and to prevent an acquiror from gaining control of Meridian without offering a
fair price to all of Meridian's stockholders. Under the Rights Plan, rights
were distributed as a dividend at the rate of one right (the "Meridian Right")
for each share of Meridian Common Stock, held by stockholders of record as of
the close of business on August 25, 1997. The Meridian Rights will expire on
August 11, 2007. Under the Rights Plan, each Meridian Right initially entitles
stockholders to buy one one-thousandth of a share of preferred stock for $30.
The Meridian Rights will be exercisable only if a person or group (other than
stockholders currently owning 15 percent of Meridian's common stock) acquires
beneficial ownership of 15 percent or more of the Meridian Common Stock or
commences a tender or exchange offer upon consummation of which such person or
group would beneficially own 15 percent or more of the Meridian Common Stock.

  If any person becomes the beneficial owner of 15 percent or more of Meridian
Common Stock, other than pursuant to a tender or exchange offer for all
outstanding shares of Meridian approved by a majority of the independent
directors not affiliated with such person, then each Meridian Right not owned
by such person or

                                       85
<PAGE>

related parties will entitle its holder to purchase, at the Meridian Right's
then current exercise price, shares of Meridian Common Stock (or, in certain
circumstances as determined by the Meridian board, cash, other property or
other securities) having a value of twice the Meridian Right's then current
exercise price. In addition, if after any person has become a 15 percent
stockholder, Meridian is involved in a merger or other business combination
transaction with another person in which Meridian does not survive or in which
its common stock is changed or exchanged, or if Meridian sells 50 percent or
more of its assets or earning power to another person, each Meridian Right will
entitle its holder to purchase, at the Meridian Right's then current exercise
price, shares of common stock of such other person having a value of twice the
Meridian Right's then current exercise price.

  Meridian is generally entitled to redeem the Meridian Rights at $0.01 per
Meridian Right at any time until ten business days (subject to extension)
following a public announcement that a 15 percent position has been acquired.

  The Rights Plan is inapplicable to the merger of Meridian with Quantum.

  Transfer Agent and Registrar. The transfer agent and registrar for the
Meridian common stock is Boston EquiServe, L.P.

stock, designated as Quantum Corporation--the DLT & Storage Systems group
Common Stock, .6 billion shares of a class of common stock, designated as
Quantum Corporation--the Hard Disk Drive group Common Stock, and 20 million
shares of preferred stock. Shares of each class of stock will have a par value
of $0.01 per share. We may issue shares of preferred stock in series, without
stockholder approval. Of the 20 million authorized shares of preferred stock,
our board of directors has designated a total of 1,600,000 shares of two series
of junior participating preferred stock in connection with our restated
stockholder rights plan. For additional information on our restated rights
plan, see "--Restated Rights Agreement."

 Dividends

  Dividends on DLT & Storage Systems group and Hard Disk Drive group common
stock are limited to our legally available funds under Delaware law and subject
to the prior payment of dividends on any preferred stock and are limited to an
amount not greater than the available dividend amount for the relevant group.

  Under Delaware law, the amount of legally available funds for dividends is
determined on the basis of our entire company, and not only the respective
groups. As a result, the amount of legally available funds will reflect the
amount of any net losses of each group, any distributions on DLT & Storage
Systems group stock, Hard Disk Drive group stock or any preferred stock and any
repurchases of DLT & Storage Systems group stock, Hard Disk Drive group stock
or preferred stock at a price per share greater than par value. Dividend
payments on the DLT & Storage Systems group stock and on the Hard Disk Drive
group stock could be precluded because legally available funds are not
available under Delaware law, even though the available dividend amount test
for the particular relevant group was met. We can not assure you that there
will be an available dividend amount for either group.

  Accordingly, the payment of dividends on either group's stock will be subject
to the prior payment of dividends on any outstanding shares of preferred stock
and the limitations described above. Subject to these
restrictions, our board of directors will be able, in its sole discretion, to
declare and pay dividends exclusively on the DLT & Storage Systems group stock,
exclusively on the Hard Disk Drive group stock or on both, in equal or unequal
amounts without having to take into account the relative available dividend
amounts for the two groups, the amount of prior dividends declared on either
class, the respective voting or liquidation rights of either class or any other
factor.

  Mandatory Dividend, Redemption or Conversion of Tracking Stock If Disposition
of Group Assets Occurs. If we dispose of all or substantially all of the
properties and assets of either group, we are required to take action that
returns the value of those assets to the holders of that group's tracking
stock. That action could take the form of a cash dividend, a redemption of
shares or a conversion into the other group's tracking stock.

  Accordingly, if we sell all or substantially all of one group's assets in a
transaction other than one described below under "--Exceptions to the Dividend,
Redemption or Conversion Requirement if a Disposition Occurs," we will:

  . pay a dividend to the holders of shares of that group's tracking stock in
    cash and/or securities or other property having a fair value equal to the
    net proceeds of the disposition; or

                                       87
<PAGE>

  . (1) if the disposition involves all of the properties and assets, redeem
    all outstanding shares of that group's tracking stock in exchange for
    cash and/or securities or other property having a fair value equal to the
    net proceeds of the disposition; or

   (2) if the disposition involves substantially all, but not all, of the
   properties and assets, redeem a number of whole shares of that group's
   tracking stock in exchange for cash and/or securities or other property
   having a fair value equal to the net proceeds of the disposition; the
   number of shares so redeemed will have in the aggregate an average market
   value, during the period of ten consecutive trading days beginning on the
   26th trading day following the disposition date, closest to the net
   proceeds; or

  . convert each outstanding share of that group's tracking stock into a
    number of shares of the other group's tracking stock equal to 110% of the
    ratio of the average market value of one share of stock of the group
    whose assets are disposed to the average market value of one share of
    stock of the other group during the 10-trading day period beginning on
    the 26th trading day following the disposition date. However, if the
    disposition is consummated after the fifth anniversary of the
    implementation of the tracking stock proposal, the number of shares to be
    received as a result of a conversion will equal 100% of the applicable
    ratio.

  We may only pay a dividend or redeem shares of tracking stock if we have
legally available funds under Delaware law and the amount to be paid to holders
is less than or equal to the available dividend amount for the group. We will
pay the dividend or complete the redemption or conversion on or prior to the
95th trading day following the disposition date.

  For purposes of determining whether a disposition has occurred,
"substantially all of the properties and assets" attributed to either group
means a portion of the properties and assets:

  . that represents at least 80% of the then fair value of the properties and
    assets attributed to that group; or

  . from which were derived at least 80% of the aggregate revenues of that
    group for the immediately preceding twelve fiscal quarterly periods.

  The "net proceeds" of a disposition means an amount equal to what remains of
the gross proceeds of the disposition after any payment of, or reasonable
provision is made as determined by our board of directors for:

  . any taxes payable by us, or which would have been payable but for the
    utilization of tax benefits attributable to the group not subject to the
    disposition, in respect of the disposition or in respect of any resulting
    dividend or redemption;

  . any transaction costs, including, without limitation, any legal,
    investment banking and accounting fees and expenses; and

  . any liabilities of or attributed to the group whose assets are disposed,
    including, without limitation, any liabilities for deferred taxes, any
    indemnity or guarantee obligations incurred in connection with the
    disposition or otherwise, any liabilities for future purchase price
    adjustments and any preferential amounts plus any accumulated and unpaid
    dividends in respect of the preferred stock attributed to that group.

  We may elect to pay the dividend or redemption price either in the same form
as the proceeds of the disposition were received or in any other combination of
cash, securities or other property that our board of directors or, in the case
of securities that have not been publicly traded for a period of at least 15
months, an independent investment banking firm, determines will have an
aggregate market value of not less than the fair value of the net proceeds.

                                       88
<PAGE>

  The following illustration demonstrates the provisions requiring a mandatory
dividend, redemption or conversion if a disposition occurs prior to the fifth
anniversary of the implementation of the tracking stock proposal.

  . If 160 million shares of DLT & Storage Systems group stock and 80 million
    shares of Hard Disk Drive group stock were outstanding,

  . the net proceeds of the disposition of substantially all, but not all, of
    the assets of the Hard Disk Drive group equals $1.5 billion,

  . the average market value of the Hard Disk Drive group stock during the
    10-trading day valuation period was $20 per share and

  . the average market value of the DLT & Storage Systems group stock during
    the same valuation period was $40 per share,

then we could do any of the following:

  (1)pay a dividend to the holders of shares of Hard Disk Drive group stock
  equal to:

<TABLE>
            <S>                                         <C>   <C>
                          net proceeds                    =     $1.5 billion
            -----------------------------------------         -----------------
            number of outstanding shares of Hard Disk         80 million shares
                        Drive group stock
                                                          =   $18.75 per share
</TABLE>

  (2)redeem for $20 per share a number of shares of Hard Disk Drive group
  stock equal to:

<TABLE>
            <S>                                        <C>     <C>
                         net proceeds                    =       $1.5 billion
            ---------------------------------------            -----------------
            average market value of Hard Disk Drive              $20 per share
                          group stock
                                                         =     75,000,000 shares
</TABLE>

  (3) convert each outstanding share of Hard Disk Drive group stock into a
      number of shares of DLT & Storage Systems group stock equal to:

<TABLE>
            <S>   <C> <C>                     <C> <C> <C> <C>
                      average market value of
                          Hard Disk Drive
            1.1     x       group stock         = 1.1   x $20 per share
                      -----------------------             -------------
                          average market                  $40 per share
                             value of
                               DLT &
                          Storage Systems
                            group stock
                                                = .55 shares
</TABLE>

  Exceptions to the Dividend, Redemption or Conversion Requirement if a
Disposition Occurs. We are not required to take any of the above actions for
any disposition of all or substantially all of the properties and assets
attributed to either group in a transaction or series of related transactions
that results in our receiving for those properties and assets primarily equity
securities of any entity which:

  . acquires those properties or assets or succeeds to the business conducted
    with those properties or assets or controls such acquiror or successor;
    and

  . is primarily engaged or proposes to engage primarily in one or more
    businesses similar or complementary to the businesses conducted by that
    group prior to the disposition, as determined by our board of directors.

The purpose of this exception is to enable us technically to dispose of
properties or assets of a group to other entities engaged or proposing to
engage in businesses similar or complementary to those of that group without

                                       89
<PAGE>

requiring a dividend on, or a conversion or redemption of, the class of common
stock of that group, so long as we hold an equity interest in that entity. A
joint venture in which we own a direct or indirect equity interest is an
example of such an acquiror. We are not required to control that entity,
whether by ownership or contract provisions.

  We are also not required to effect a dividend, redemption or conversion if
the disposition is:

  . of all or substantially all of our properties and assets in one
    transaction or a series of related transactions in connection with our
    dissolution, liquidation or winding up and the distribution of our assets
    to stockholders;

  . on a pro rata basis, such as in a spin-off, to the holders of all
    outstanding shares of the tracking stock of the group whose assets are
    disposed; or

  . made to any person or entity controlled by us, as determined by our board
    of directors.

  Notices If Disposition of Group Assets Occurs. Not later than the 20th
trading day after the consummation of a disposition, we will announce publicly
by press release:

  . the estimated net proceeds of the disposition;

  . the number of shares outstanding of the tracking stock of the group whose
    assets are disposed; and

  . the number of shares of that group's tracking stock into or for which
    convertible securities are then convertible, exchangeable or exercisable
    and the conversion, exchange or exercise price of those convertible
    securities.

  Not earlier than the 36th trading day and not later than the 40th trading day
after the consummation of the disposition, we will announce publicly by press
release whether we will pay a dividend or redeem shares of tracking stock with
the net proceeds of the disposition or convert the shares of tracking stock of
the group whose assets are disposed into the other groups of tracking stock.

  We will mail to each holder of shares of the group whose assets are disposed
the additional notices and other information required by the restated
certificate of incorporation.

  Conversion of Common Stock at Option of Quantum at Any Time. During the five
years following the implementation of the tracking stock capital structure, our
board of directors may at any time convert each share of DLT & Storage Systems
group stock into a number of shares of Hard Disk Drive group stock equal to
110% of the ratio of the average market values of the DLT & Storage Systems
group stock to the Hard Disk Drive group stock over a 20-trading day period.
Conversely, during that period our board of directors may also at any time
convert each share of Hard Disk Drive group stock into a number of shares of
DLT & Storage Systems group stock equal to 110% of the ratio of the average
market values of the Hard Disk Drive group stock to the DLT & Storage Systems
group stock over a 20-trading day period. Following the fifth anniversary
of the implementation of the tracking stock proposal, the number of shares to
be received as a result of a conversion will equal 100% of the applicable
ratio. This means that the holders of the tracking stock being converted will
not receive any premium in a conversion. We will calculate the ratio of average
market values as of the fifth trading day prior to the date we mail the
conversion notice to holders.

  However, if a tax event occurs at any time, a factor of 100% rather than 110%
will be applied to the ratio of the average market values. This means that the
holders of the tracking stock being converted will not receive any premium in a
conversion.

  "Tax event" means the receipt by our company of an opinion of a tax advisor
that, as a result of:

  . any amendment to, or change in, the laws or regulations interpreting the
    laws of the United States or any political subdivision or taxing
    authority, including any announced proposed change by an applicable
    legislative committee or its chair in those laws or by an administrative
    agency in those regulations; or

                                       90
<PAGE>

  . any official or administrative pronouncement, action or judicial decision
    interpreting or applying those laws or regulations,

it is more likely than not that for United States federal income tax purposes:

  . Quantum or our stockholders are, or at any time in the future will be,
    subject to tax upon the issuance of shares of either DLT & Storage
    Systems group stock or Hard Disk Drive group stock; or

  . either DLT & Storage Systems group stock or Hard Disk Drive group stock
    is not or at any time in the future will not be treated solely as stock
    of Quantum.

For purposes of rendering this opinion, the tax advisor will assume that any
legislative or administrative proposals will be adopted or enacted as proposed.

  These provisions allow us the flexibility to recapitalize the two tracking
stocks into one class of common stock that would, after the recapitalization,
represent an equity interest in all of our businesses. The optional conversion
or redemption could be exercised at any future time if our board of directors
determines that, under the facts and circumstances then existing, an equity
structure consisting of two tracking stocks was no longer in the best interests
of all of our stockholders. A conversion could be exercised, however, at a time
that is disadvantageous to the holders of one of the tracking stocks. For
additional information on the risks of a conversion and the limited remedies
available to stockholders, see "Risk Factors--Stockholders may not have any
remedies for breach of fiduciary duties if any action by directors and officers
has a disadvantageous effect on either class of tracking stock" and "--Numerous
potential conflicts of interest exist between classes of tracking stock which
may be difficult to resolve by our board of directors or which may be resolved
adversely to one of the classes."

  Conversion would be based upon the relative market values of the DLT &
Storage Systems group stock and the Hard Disk Drive group stock. Many factors
could affect the market values of the DLT & Storage Systems group stock or the
Hard Disk Drive group stock, including our results of operations and those of
each of the groups, trading volume and general economic and market conditions.
Market values could also be affected by decisions by our board of directors or
our management that investors perceive to affect differently one class of
tracking stock compared to the other. These decisions could include changes to
our management and allocation policies, transfers of assets between groups,
allocations of corporate opportunities and financing resources between the
groups and changes in dividend policies.

  The following illustration demonstrates the calculation of the number of
shares issuable upon conversion of one class of common stock into shares of the
other class at our option if:

  . a tax event has not occurred,

  . five years have not elapsed since the implementation of the tracking
    stock proposal,

  . 160 million shares of DLT & Storage Systems group stock and 80 million
    shares of Hard Disk Drive group stock were outstanding immediately prior
    to a conversion,

  . the average market value of one share of the Hard Disk Drive group stock
    over the 20-trading day valuation period was $20, and

  . the average market value of one share of the DLT & Storage Systems group
    stock over the same valuation period was $40,

then each share of Hard Disk Drive group stock could be converted into .55
shares of DLT & Storage Systems group stock based on the following calculation:

<TABLE>
            <S>            <C>                   <C>                   <C>                   <C>
            1.1              x                   $20                     =                   .55 shares
                                                 ---
                                                 $40
</TABLE>

                                       91
<PAGE>

  Redemption in Exchange for Stock of Subsidiary. Although we currently have no
intention to do so, our board of directors may redeem on a pro rata basis all
of the outstanding shares of DLT & Storage Systems group stock or Hard Disk
Drive group stock for shares of the common stock of one or more of our wholly-
owned subsidiaries which own all of the assets and liabilities attributed to
the relevant group. We may redeem shares of tracking stock for subsidiary stock
only if we have legally available funds under Delaware law.

  As a result of a redemption, holders of each class of tracking stock would
hold securities of separate legal entities operating in distinct lines of
business. This redemption could be authorized by our board of directors at any
time in the future if it determines that, under the facts and circumstances
then existing, an equity structure comprised of the DLT & Storage Systems group
stock and the Hard Disk Drive group stock is no longer in the best interests of
all of our stockholders as a whole.

  Selection of Shares for Redemption. If less than all of the outstanding
shares of a class of tracking stock are to be redeemed, we will redeem those
shares proportionately from among the holders of outstanding shares of that
tracking stock or by such method as may be determined by our board of directors
to be equitable.

  Fractional Interests; Transfer Taxes. We will not be required to issue
fractional shares of any capital stock or any fractional securities to any
holder of either class of tracking stock upon any conversion, redemption,
dividend or other distribution described above. If a fraction is not issued to
a holder, we will pay cash instead of that fraction.

  We will pay all documentary, stamp or similar issue or transfer taxes that
may be payable in respect of the issue or delivery of any shares of capital
stock and/or other securities on conversion or redemption of shares.

 Voting Rights

  Variable Voting. Currently, holders of our existing common stock have one
vote per share on all matters submitted to stockholders.

  Under the restated certificate of incorporation the entire voting power of
our stockholders will be vested in the holders of tracking stock. Holders of
the tracking stocks are entitled to vote on any matter on which our
stockholders are, by law or by the provisions of the restated certificate of
incorporation or our by-laws, entitled to vote, except as otherwise provided by
law, by the terms of any outstanding preferred stock or by any provision of the
restated certificate of incorporation restricting the power to vote on a
specified matter to other stockholders.

  Holders of tracking stock vote as a single class on each matter on which
holders of common stock are generally entitled to vote.

  On all matters as to which both classes of tracking stock vote together as a
single class:

  . each share of DLT & Storage Systems group stock has one vote; and

  . each share of Hard Disk Drive group stock has a number of votes equal to
    the quotient of the average market value of a share of Hard Disk Drive
    group stock over the 20-trading day period ending on the 10th trading day
    prior to the record date for determining the holders of tracking stock
    entitled to vote, divided by the average market value of a share of DLT &
    Storage Systems group stock over the same period.

  Accordingly, the relative per share voting rights of the DLT & Storage
Systems group stock and the Hard Disk Drive group stock fluctuate depending on
changes in the relative market values of shares of the classes of tracking
stock.

  The DLT & Storage Systems group stock currently has a substantial majority of
the voting power because the aggregate market value of the outstanding shares
of DLT & Storage Systems group stock is currently substantially greater than
the aggregate market value of the outstanding shares of Hard Disk Drive group
stock.

                                       92
<PAGE>

  If shares of only one class of tracking stock are outstanding, each share of
that class will have one vote. If either class of tracking stock is entitled to
vote as a separate class with respect to any matter, each share of that class
will, for purpose of such vote, have one vote on such matter.

  Fluctuations in the relative voting rights of the DLT & Storage Systems group
stock and the Hard Disk Drive group stock could influence an investor
interested in acquiring and maintaining a fixed percentage of the voting power
of our stock to acquire such percentage of both classes of tracking stock, and
would limit the ability of investors in one class to acquire for the same
consideration relatively more or less votes per share than investors in the
other class.

  The holders of DLT & Storage Systems group stock and Hard Disk Drive group
stock will not have any rights to vote separately as a class on any matter
coming before our stockholders, except for the limited class voting rights
provided under Delaware law described below, by New York Stock Exchange rules
or as determined by our board of directors. In addition to the approval of the
holders of a majority of the voting power of all shares of tracking stock
voting together as a single class, the approval of a majority of the
outstanding shares of the DLT & Storage Systems group stock or the Hard Disk
Drive group stock, voting as a separate class, would be required under Delaware
law to approve any amendment to the restated certificate of incorporation that
would change the par value of the shares of the class or alter or change the
powers, preferences or special rights of the shares of the class so as to
affect them adversely. As permitted by Delaware law, the restated certificate
of incorporation provides that an amendment to the restated certificate of
incorporation that increases or decreases the number of authorized shares of
DLT & Storage Systems group stock or Hard Disk Drive group stock only requires
the approval of the holders of a majority of the voting power of all shares of
tracking stock, voting together as a single class, and does not require the
approval of the holders of the class of tracking stock affected by the
amendment, voting as a separate class.

  The following illustration demonstrates the calculation of the number of
votes each share of Hard Disk Drive group stock would be entitled on all
matters on which holders of DLT & Storage Systems group stock and Hard Disk
Drive group stock vote as a single class. If the average market value for the
20-trading day valuation period was $20 for the Hard Disk Drive group stock and
$40 for the DLT & Storage Systems group stock, each share of DLT & Storage
Systems group stock would have one vote and each share of Hard Disk Drive group
stock would have 0.5 votes based on the following calculation:

<TABLE>
            <S>                          <C>                                               <C>
            $20                            =                                               0.5 votes
            ---
            $40
</TABLE>

Assuming 160 million shares of DLT & Storage Systems group stock and 80 million
shares of Hard Disk Drive group stock were outstanding, the shares of DLT &
Storage Systems group stock would represent 80% of our total voting power and
the shares of Hard Disk Drive group stock would represent 20% of our total
voting power.

  Cumulative Voting. A holder of our existing common stock may, in the election
of directors, cumulate his or her votes in order to give one candidate a number
of votes equal to the number of directors to be elected multiplied by the total
number of votes to which such holder's shares of DLT & Storage Systems group
stock and shares of Hard Disk Drive group stock are entitled. We currently have
six directors. Alternatively, a holder may distribute such number of votes
among up to the number of directors to be elected.

  Liquidation

  Under the restated certificate of incorporation, in the event of our
dissolution, liquidation or winding up, the holders of DLT & Storage Systems
group stock and Hard Disk Drive group stock will be entitled to receive our
assets remaining for distribution to holders of common stock on a per share
basis in proportion to the liquidation units per share of such class, after
payment or provision for payment of the debts and other liabilities and full
preferential amounts to which holders of any preferred stock are entitled.

                                       93
<PAGE>

  Each share of DLT & Storage Systems group stock will have one liquidation
unit. Each share of Hard Disk Drive group stock will have a number of
liquidation units equal to the quotient of the average market value of a share
of Hard Disk Drive group stock over the 20-trading day period ending on the
40th trading day after the initial issuance of the DLT & Storage Systems group
stock and the Hard Disk Drive group stock under the tracking stock proposal,
divided by the average market value of a share of DLT & Storage Systems group
stock over the same period.

  After the number of liquidation units to which each share of Hard Disk Drive
group stock is entitled has been calculated in accordance with this formula,
that number will not be changed without the approval of holders of the class of
common stock adversely affected except as described below. As a result, after
the date of the calculation of the number of liquidation units to which the
Hard Disk Drive group stock is entitled the liquidation rights of the holders
of the respective classes of tracking stock may not bear any relationship to
the relative market values or the relative voting rights of the two classes. We
consider that liquidation is a remote contingency, and our financial advisors
believe that, in general, these liquidation provisions will be immaterial to
trading in the DLT & Storage Systems group stock and the Hard Disk Drive group
stock.

  No holder of DLT & Storage Systems group stock will have any special right to
receive specific assets of the DLT & Storage Systems group and no holder of
Hard Disk Drive group stock will have any special right to receive specific
assets of the Hard Disk Drive group in the case of our dissolution, liquidation
or winding up.

   If we subdivide or combine the outstanding shares of either class of
tracking stock or declare a dividend or other distribution of shares of either
class of tracking stock to holders of that class of tracking stock, the number
of liquidation units of either class of tracking stock will be appropriately
adjusted. This adjustment will be made by our board of directors, to avoid any
dilution in the aggregate, relative liquidation rights of any class of tracking
stock.

  Neither a merger nor consolidation of Quantum into or with any other
corporation, nor any sale, transfer or lease of all or any part of our assets,
will, alone, be deemed a liquidation or winding up of Quantum, or cause the
dissolution of Quantum, for purposes of these liquidation provisions.

 Determinations by the Board of Directors

  Any determinations made in good faith by our board of directors under any
provision described under "Description of DLT & Storage Systems group stock and
Hard Disk Drive group stock," and any determinations with respect to any group
or the rights of holders of shares of either class of common stock, will be
final and binding on all of our stockholders, subject to the rights of
stockholders under applicable Delaware law and under the federal and state
securities laws.

 Preemptive Rights

  Neither the holders of the DLT & Storage Systems group stock nor the holders
of the Hard Disk Drive group stock will have any preemptive rights or any
rights to convert their shares into any other securities of Quantum.

Restated Rights Agreement

   We have issued existing preferred share purchase rights to all holders of
our common stock under an amended and restated rights agreement between our
company and Harris Trust and Savings Bank, as rights agent which is
incorporated by reference herein.

  These rights include:

  . one right for each share of DLT & Storage Systems group stock, which will
    allow holders to purchase shares of a newly designated Series B Junior
    Participating Preferred Stock of Quantum if a "distribution date" occurs;
    and

                                       94
<PAGE>

  . one right for each share of Hard Disk Drive group stock, which will allow
    holders to purchase shares of a newly designated Series C Junior
    Participating Preferred Stock of Quantum if a "distribution date" occurs.

  We refer to the DLT & Storage Systems group rights and the Hard Disk Drive
group rights as the "rights."

  A "distribution date" will occur upon the earlier of:

  . the tenth day after a public announcement that a person or group of
    affiliated or associated persons other than us or our employee benefit
    plans (an "acquiring person") has acquired beneficial ownership of
    (1) 20% or more of the shares of DLT & Storage Systems group stock then
    outstanding or (2) 20% or more of the shares of Hard Disk Drive group
    stock then outstanding; or

  . the tenth business day or a later day determined by our board of
    directors following the commencement of a tender or exchange offer that
    would result in such person or group beneficially owning such number of
    shares.

Until the distribution date, the rights will be transferred only with the
common stock.

  Following the distribution date, holders of rights will be entitled to
purchase from us:

  . in the case of a DLT & Storage Systems group right, one one-thousandth of
    a share of Series B Junior Participating Preferred Stock at a purchase
    price to be determined by our board of directors, subject to adjustment;
    and

  . in the case of an Hard Disk Drive group right, one one-thousandth of a
    share of Series C Participating Junior Preferred Stock at a purchase
    price to be determined by our board of directors, subject to adjustment.

  If any person or group becomes an acquiring person:

  . The Hard Disk Drive group right will entitle its holder to purchase, at
    the Series B purchase price, a number of shares of DLT & Storage Systems
    group stock with a market value equal to twice the Series B Purchase
    Price; and

  . The Hard Disk Drive group right will entitle its holder to purchase, at
    the Series C purchase price, a number of shares of Hard Disk Drive group
    stock with a market value equal to twice the Series C Purchase Price.

  In certain circumstances after the rights have been triggered, we may
exchange the rights, other than rights owned by an acquiring person, at an
exchange ratio of one share of DLT & Storage Systems group stock per the DLT &
Storage Systems group right and one share of Hard Disk Drive group stock per
the Hard Disk Drive group right.

  If, following the time a person becomes an acquiring person:

  . Quantum is acquired in a merger or other business combination transaction
    and Quantum is not the surviving corporation;

  . any person consolidates or merges with Quantum and all or part of the
    common stock is converted or exchanged for securities, cash or property
    of any other person; or

  . 50% or more of Quantum's assets or earning power is sold or transferred,

each the DLT & Storage Systems group right and each Hard Disk Drive group right
will entitle its holder to purchase, for the Series B purchase price or Series
C purchase price, a number of shares of common stock of the surviving entity in
any such merger, consolidation or other business combination or the purchaser
in any such sale or transfer with a market value equal to twice the Series B
purchase price or Series C purchase price.

                                       95
<PAGE>

  The rights will expire on August 4, 2008, unless we extend or terminate them
as described below.

   At any time until a public announcement that an acquiring person has become
such, our board of directors may redeem all of the rights at a price of $0.01
per right. On the redemption date, the right to exercise the rights will
terminate and the only right of the holders of rights will be to receive this
price.

  A holder of a right will not have any rights as a stockholder of Quantum,
including the right to vote or to receive dividends, until a right is
exercised.

  At any time prior to the occurrence of a distribution date, we may, without
the approval of any holders of rights, supplement or amend any provision of the
restated rights agreement in any manner, whether or not such supplement or
amendment is adverse to any holders of the rights. From and after the
occurrence of a distribution date, we may, without the approval of any holders
of rights, supplement or amend the restated rights agreement:

  . to cure any ambiguity,

  . to correct or supplement any provision that may be defective or
    inconsistent,

  . subject to certain exceptions, to shorten or lengthen any time period
    thereunder, or

  . in any manner that we may deem necessary or desirable and which does not
    adversely affect the interests of the holders of Rights, other than an
    acquiring person.

  The restated rights agreement contains provisions designed to prevent the
inadvertent triggering of the rights. For example, it gives a person who has
inadvertently acquired 20% or more of the outstanding shares of a class of
tracking stock and does not have any intention of changing or influencing the
control of Quantum the opportunity to sell a sufficient number of shares so
that such acquisition would not trigger the rights. In addition, the rights
will not be triggered and a divestiture of shares will not be required by our
repurchase of shares of tracking stock outstanding which could raise the
proportion of shares held by a person to over the applicable 20% threshold.
However, any person who exceeds such threshold as a result of our stock
repurchases will trigger the rights if the person subsequently acquires any
additional shares of tracking stock.

  We have filed a copy of the form of the restated rights agreement with the
SEC as an exhibit to the Form 8-A filed with the SEC on July 21, 1999 and
incorporate it by reference herein. Upon request, we will provide you with a
copy of the restated rights agreement free of charge.

Certain Anti-Takeover Provisions of Delaware Law and the Restated Certificate
of Incorporation, the By-laws and the Restated Rights Agreement

  The following discussion concerns certain provisions of Delaware law, the
restated certificate of incorporation, our by-laws, and the restated rights
agreement that could be viewed as having the effect of discouraging an attempt
to obtain control of Quantum.

 Delaware Law

  Section 203 of the Delaware General Corporation Law. Under certain
circumstances, Section 203 of the Delaware General Corporation Law limits the
ability of an "interested stockholder" to effect various business combinations
with Quantum for a three-year period following the time that such stockholder
became an interested stockholder. An "interested stockholder" is defined as a
holder of 15% or more of the outstanding voting stock.

  An interested stockholder may engage in a business combination transaction
with Quantum within the three-year period only if:

  . our board of directors approved the transaction before the stockholder
    became an interested stockholder or approved the transaction in which the
    stockholder became an interested stockholder;

                                       96
<PAGE>

  . the interested stockholder acquired at least 85% of the voting stock in
    the transaction in which it became an interested stockholder; or

  . our board of directors and the holders of shares entitled to cast two-
    thirds of the votes entitled to be cast by all of the outstanding voting
    shares held by all disinterested stockholders approve the transaction.

 Restated Certificate of Incorporation and By-laws

  Authorized Shares. The restated certificate of incorporation provides that we
may from time to time issue shares of preferred stock in one or more series,
the terms of which will be determined by our board of directors, and common
stock of either class. We will not solicit approval of our stockholders unless
our board of directors believes that approval is advisable or is required by
New York Stock Exchange regulations or Delaware law. This could enable our
board of directors to issue shares to persons friendly to current management
which could render more difficult or discourage an attempt to obtain control of
Quantum by means of a merger, tender offer, proxy contest or otherwise, and
protect the continuity of our management. These additional shares also could be
used to dilute the stock ownership of persons seeking to obtain control of our
company.

  Stockholder Proposals and Nominations. The by-laws provide that any
stockholder may present a nomination for a directorship at an annual meeting of
stockholders only if advance notice of such nomination has been delivered to
Quantum not less than 20 days or more than 60 days prior to the meeting. If
less than 30 days notice or public disclosure of the date of the meeting is
given or made to stockholders, notice by the stockholder must be received not
later than 10 days after the notice was mailed or the disclosure made.
Similarly, any stockholder may present a proposal at an annual meeting only if
advance notice of the proposal has been delivered to Quantum not less than 60
days or more than 90 days prior to the meeting. If less than 70 days notice or
public disclosure of the date of the meeting is given or made to stockholders,
notice by the stockholder must be received not later than 10 days after the
notice was mailed or the disclosure made. The foregoing notices must describe
the proposal to be brought at the meeting or the nominee for director, as
applicable, as well as provide personal information regarding the stockholder
giving the notice, the number of shares owned by the stockholders, his or her
interest in such proposal and, with respect to nominations for directorships,
whether the stockholder intends to request cumulative voting in the election of
directors at the meeting. For additional information on cumulative voting, see
"--Description of DLT & Storage Systems group stock and Hard Disk Drive group
stock--Voting Rights--Cumulative Voting." These procedural requirements could
have the effect of delaying or preventing the submission of matters proposed by
any stockholder to a vote of the stockholders.

 Restated Rights Agreement

  As described under "--Restated Rights Agreement," the restated rights
agreement permits disinterested stockholders to acquire additional shares of
Quantum or of an acquiring company at a substantial discount in the event of
certain described changes in control. The restated rights agreement is intended
to discourage anyone from buying shares of common stock having more than 20% of
the voting power of either class of tracking stock shares without board of
directors' approval.

                       COMPARISON OF STOCKHOLDERS' RIGHTS

  After consummation of the merger you will become a stockholder of Quantum. As
a stockholder of Meridian, your rights are presently governed by Delaware law,
by the Meridian Certificate of Incorporation, as amended, and by Meridian's by-
laws. Both Quantum and Meridian are incorporated in the State of Delaware.
There are certain material differences between the rights and privileges of the
holders of Meridian common stock and the holders of the Quantum DLT & Storage
Systems group and Hard Disk Drive group common stock. The following discussion
summarizes those differences. This summary does not purport to be complete and
is qualified in its entirety by reference to the Meridian Certificate of
Incorporation, by-laws and Rights Plan, the Quantum Restated Certificate of
Incorporation, by-laws and preferred share rights plan, the sections entitled
"Description of Quantum Capital Stock" and "Description of Meridian Capital
Stock" and the relevant provisions of Delaware law.

  Percentage of Voting Stock; Influence over Affairs. Upon completion of the
merger, the percentage ownership of Quantum by each former Meridian stockholder
will be significantly less than that stockholder's current percentage ownership
of Meridian. Accordingly, former Meridian stockholders will have a
significantly smaller voting influence over the affairs of Quantum than they
currently enjoy over the affairs of Meridian.

  Rights Plans. Meridian's Rights Plan is described above under "Description of
Meridian Capital Stock". The Quantum board has also adopted a preferred shares
rights plan (the "Quantum Rights Plan") that is designed to deter hostile
takeover attempts, including the accumulation of shares in the open market or
through private transactions, and to prevent an acquiror from gaining control
of Quantum without offering a fair price to all of Quantum's stockholders. The
Quantum Rights Plan is similar to Meridian's Rights Plan but covers two classes
of common stock. The Quantum Rights will expire on August 4, 2008. Each Quantum
Right also entitles stockholders to buy one one-thousandth of a share of
preferred stock, but at an exercise price at a purchase price to be determined
by Quantum's board of directors rather than $30 as in the case of the Meridian
Rights Plan. The beneficial ownership percentage which triggers the
exercisability of the Quantum Rights is 20 percent rather than 15 percent as in
the case of the Meridian Rights Plan. The Quantum Rights Plan is described in
more detail in the section entitled "Description of Quantum Capital Stock".

  Special Meeting of the Stockholders. Under Delaware 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 by-laws. The
Meridian by-laws provide that special meetings of the stockholders may be
called by the President, by the Chairman of the board, by the board of
directors or by the holders of at least 10% of the total voting power of all
outstanding shares of stock entitled to vote. The Quantum by-laws provide that
special meetings of the stockholders may be called by resolution of the board
of directors or by the holders of shares entitled to cast not less than 10% of
the votes at a special meeting of stockholders.

  Notice of Special Meeting. The Quantum by-laws provide that if a special
meeting is called by any person or persons other than the Board of Directors,
the officer receiving the request shall cause notice to be promptly given to
the stockholders entitled to vote. A meeting will be held not less than thirty-
five (35) nor more than sixty (60) days after the receipt of the request.

  Action by Written Consent of Stockholders. Under Delaware law, unless the
certificate of incorporation provides otherwise, any action to be taken by
stockholders may be taken without a meeting, without prior notice, and without
a vote, if the stockholders having the number of votes that would be necessary
to take such action at a meeting at which all stockholders were present and
voted consent to the action in writing. Neither the Quantum Certificate nor the
Meridian Certificate eliminate actions by written consent of the stockholders.

  Stockholder Proposals for Meetings. The Meridian by-laws provide that at any
meeting of the stockholders, to be timely, a stockholder's notice must be
delivered to or mailed and received at the principal place of business of the
corporation not less than seventy-five (75) days in advance of the first
anniversary date of mailing of Meridian's proxy statement released to
stockholders in connection with the previous year's

                                       98
<PAGE>

meeting of stockholders; provided however, that in the event that the annual
meeting was held in the previous year or the date of the annual meeting has
been changed by more than thirty (30) days from the date contemplated by the
previous year's proxy statement, notice by the stockholder must be received a
reasonable time before the solicitation is made. The Quantum by-laws provide
that, to be timely, a stockholder's notice must be delivered to or mailed and
received at the principal place of business of the corporation not less than
sixty (60) days nor more than ninety (90) days prior to the meeting; provided,
however, that in the event that less than seventy (70) days notice or prior
public disclosure of the date of the meeting is given or made to stockholders,
notice by the stockholder to be timely must be received not later than the
close of business on the tenth day following the day on which such notice of
the date of the meeting was mailed or such public disclosure was made.

  Cumulative Voting. The Meridian Certificate and by-laws do not provide for
cumulative voting in elections of directors. Without cumulative voting, the
holders of a majority of the shares present at any annual meeting will be able
to elect all of the directors to be elected at that meeting, and no person
could be elected without the support of a majority of the stockholders. thus, a
person or persons holding shares or proxies representing less than a majority
of the shares present will not be able to elect any directors as they might if
cumulative voting were applicable. The Quantum Certificate and the Quantum by-
laws provide for cumulative voting by stockholders in elections of directors.
The Quantum by-laws require that timely notice be given of any stockholder's
intention to cumulate votes.

  Nominations for Board of Directors, Advance Notice of Stockholder Nominees
and Cumulative Voting. The Meridan by-laws provide that nominations for
election to the board of directors must be made by the board of directors or by
any stockholder of any outstanding class of capital stock of the corporation
entitled to vote for the election of directors. Nominations, other than those
made by the board of directors must be preceded by verification in writing
received by the Secretary of the corporation not less than seventy-five
(75) days in advance of the first anniversary date of mailing of Meridian's
proxy statement released to stockholders in connection with the previous year's
annual meeting of stockholders. The Quantum by-laws provide that nominations of
persons for election to the board of directors of the corporation, other than
those made by or at the direction of the board of directors, shall be made
pursuant to timely notice in writing to the Secretary of Quantum. Timely notice
must also be given of any stockholder's intention to cumulate votes in the
election of directors at a meeting. In either case, to be timely, a
stockholder's notice is deemed delivered to or mailed and received at the
principal executive officers of the corporation not less than twenty (20) days
nor more than sixty (60) days prior to the meeting; provided, however, that in
the event less than thirty (30) days notice or prior public disclosure of the
date of the meeting is given or made to stockholders, notice by the stockholder
to be timely must be so received not later than the close of business on the
tenth day following the day on which such notice of the date of the meeting was
mailed or such public disclosure was made.

  Number of Directors. The Meridian by-laws provide that the number of
directors shall be fixed from time to time by resolution of the Meridian board
or by the stockholders at an annual meeting of Meridian but in no event shall
be less than five nor more than seven. The Meridian board is currently fixed at
five (5) members. The Quantum by-laws provide that the number of directors
shall be set at seven and, thereafter, may be changed by a duly adopted
amendment to the Quantum certificate of incorporation or by an amendment to the
Quantum by-laws adopted by the vote or written consent of a majority of the
stock issued and outstanding and entitled to vote or by resolution of a
majority of the Board of Directors. Quantum currently has six directors.

  Removal of Directors. The Meridian Certificate and by-laws do not address the
removal of directors. However, under Delaware law, any director or the entire
board of directors may be removed, with or without cause, by the holders of a
majority of the shares then entitled to vote at an election of directors except
in the case of a corporation with cumulative voting. Quantum's by-laws provide
for removal of directors consistent with Delaware law. Stockholders of Quantum
are entitled to cumulative voting. If less than the entire board of directors
of Quantum is to be removed, no director of Quantum may be removed without
cause if the votes cast against his removal would be sufficient to elect him if
then cumulatively voted at an election of the entire board of directors of
Quantum.

                                       99
<PAGE>

  Exculpation of Directors. Each of Quantum and Meridian has included in its
Certificate of Incorporation a provision which eliminates the personal
liability of its directors from monetary damages resulting from a breach of
fiduciary duty as a director to the fullest extent permitted by the DGCL.

  Indemnification of Directors, Officers and Others. The Meridian by-laws
require indemnification of its directors, officers, employees and agents to the
maximum extent and in the manner permitted by the DGCL. The Quantum By-laws
require indemnification of a director or officer if he acted in good faith and
in a manner he reasonably believed to be in or not opposed to the best
interests of the corporation, and, with respect to any criminal action or
proceeding, had no reasonable cause to believe his conduct was unlawful.
Pursuant to the Quantum By-laws, the termination of any action, suit, or
proceeding by judgment, order, settlement, conviction, or upon a plea of nolo
contendere or its equivalent, does not, of itself, create a presumption that
the person did not act in good faith and in a manner which he reasonably
believed to be in or not opposed to the best interests of the corporation, and,
with respect to any criminal action or proceeding, had a reasonable cause to
believe that his conduct was unlawful.

  Amendment, Repeal of By-laws. Both the Meridian Certificate and the Quantum
Certificate provide that the by-laws can be amended or repealed either by the
affirmative vote of the holders of a majority of the outstanding voting shares
or by the Board of Directors.

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS

To the Board of Directors and Stockholders of
Quantum Corporation

We have audited the accompanying combined balance sheets of the DLT & Storage
Systems group (as described in Note 1) of Quantum Corporation as of March 31,
1998 and 1999 and the related combined statements of operations, group equity,
and cash flows for each of the three years in the period ended March 31, 1999.
These financial statements are the responsibility of Quantum Corporation'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 the DLT & Storage Systems
group at March 31, 1998 and 1999 and the results of its operations and its cash
flows for each of the three years in the period ended March 31, 1999, in
conformity with generally accepted accounting principles.

As more fully described in Note 1 to these financial statements, the DLT &
Storage Systems group is a business group of Quantum Corporation; accordingly,
the combined financial statements of the DLT & Storage Systems group should be
read in conjunction with the audited consolidated financial statements of
Quantum Corporation.

                          DLT & STORAGE SYSTEMS GROUP

                     NOTES TO COMBINED FINANCIAL STATEMENTS


Note 1 Summary of Significant Accounting Policies

The accompanying combined financial statements should be read in conjunction
with the consolidated financial statements of Quantum Corporation ("Quantum").

Nature of Business. Quantum operates its business through two separate groups:
the DLT & Storage Systems group and the Hard Disk Drive group. The DLT &
Storage Systems group and the Hard Disk Drive group are referred to as the
"groups."

The DLT & Storage Systems group designs, develops, manufactures, licenses and
markets DLTtape drives and media, tape libraries and solid state storage
systems. DLTtape is the DLT & Storage Systems group's half-inch tape technology
that is the de facto industry standard for data back-up in the mid-range server
market.

The Hard Disk Drive group designs desktop hard disk drives to meet the storage
requirements of entry-level to high-end desktop PCs in home and business
environments. The Hard Disk Drive group also designs high-end hard disk drives
for the demanding storage needs of network servers, workstations and storage
sub-systems.

   The Board of Directors (the "Board") of Quantum has recommended stockholder
approval of a proposal (the "tracking stock proposal") that would create two
classes of tracking stock intended to reflect separately the performance of the
DLT & Storage Systems group and the Hard Disk Drive group. Under the tracking
stock proposal, Quantum's Certificate of Incorporation would be amended and
restated (the "Restated Certificate of Incorporation") to (i) designate a new
class of Quantum Corporation--the DLT & Storage Systems group Common Stock,
$.01 par value per share, (ii) designate a new class of Quantum Corporation--
the Hard Disk Drive group common stock, $.01 par value per share , and (iii)
reclassify each authorized share of existing common stock, $.01 par value per
share as one share of DLT & Storage Systems group stock and one-half share of
the Hard Disk Drive group stock.

The combined financial statements of the groups comprise all of the accounts
included in the corresponding consolidated financial statements of Quantum. The
separate group combined financial statements give effect to the accounting
policies that will be applicable upon implementation of the tracking stock
proposal. The separate the DLT & Storage Systems group and the Hard Disk Drive
group financial statements have been prepared on a basis that management
believes to be reasonable and appropriate and include (i) the historical
balance sheets, results of operations, and cash flows of businesses that
comprise each of the groups, with all significant intragroup transactions and
balances eliminated, (ii) in the case of the DLT & Storage Systems group's
financial statements, corporate assets and liabilities of Quantum and related
transactions identified with the DLT & Storage Systems group, including
allocated portions of Quantum's debt and selling, general and administrative
costs, and (iii) in the case of the Hard Disk Drive group's financial
statements, corporate assets and liabilities of Quantum and related
transactions identified with the Hard Disk Drive group, including allocated
portions of Quantum's debt and selling, general and administrative costs.

Holders of DLT & Storage Systems group stock and Hard Disk Drive group stock
will be stockholders of a single company. The DLT & Storage Systems group and
the Hard Disk Drive group are not separate legal entities. As a result,
stockholders will continue to be subject to all of the risks of an investment
in Quantum and all of Quantum's business, assets and liabilities. The issuance
of DLT & Storage Systems group stock and Hard Disk Drive group stock and the
allocation of assets or liabilities and stockholders' equity between the DLT &
Storage Systems group and the Hard Disk Drive group will not result in a
distribution or spin-off to stockholders of any of Quantum's assets or
liabilities and will not affect ownership of any of Quantum's assets or
responsibility for Quantum's liabilities or those of Quantum's subsidiaries.
The assets Quantum attributes to

                                      F-7

                          DLT & STORAGE SYSTEMS GROUP

              NOTES TO COMBINED FINANCIAL STATEMENTS--(Continued)

one group could be subject to the liabilities of the other group. If Quantum is
unable to satisfy one group's liabilities out of the assets attributed to it,
Quantum may be required to satisfy those liabilities with assets Quantum has
attributed to the other group. Holders of DLT & Storage Systems group stock and
Hard Disk Drive group stock generally will not have stockholder rights specific
to their corresponding group. Instead, holders will have customary stockholder
rights relating to Quantum as a whole.

Holders of tracking stock will not have any rights related to their
corresponding group except as set forth in provisions relating to dividend
rights and requirements for a mandatory dividend, redemption or conversion upon
the disposition of all or substantially all of the assets of their
corresponding group, or have any right to vote on matters as a separate voting
group other than in limited circumstances as provided under Delaware law or by
New York Stock Exchange rules. The relative voting power of DLT & Storage
Systems group stock and Hard Disk Drive group stock will fluctuate from time to
time, with each share of DLT & Storage Systems group stock having one vote and
each share of Hard Disk Drive group stock having a number of votes, based upon
the ratio, over a specified period, of the average market values of one share
of DLT & Storage Systems group stock and of one share of Hard Disk Drive group
stock. This formula is intended to give each class of tracking stock a number
of votes proportionate to its aggregate market capitalization at the time of
any vote. Accordingly, changes in the market value of DLT & Storage Systems
group stock and Hard Disk Drive group stock will affect the relative voting
rights of a class of tracking stock. It is expected that initially the holders
of DLT & Storage Systems group stock will have a substantial majority of the
voting power of Quantum.

Financial effects arising from one group that affect the Quantum's consolidated
results of operations or financial condition could, if significant, affect the
results of operations or financial condition of the other group and the market
price of the class of tracking stock relating to the other group. Any net
losses of the DLT & Storage Systems group or the Hard Disk Drive group, and
dividends or distributions on, or repurchases of, DLT & Storage Systems group
stock or Hard Disk Drive group stock, or repurchases of preferred stock at a
price per share greater than par value, will reduce the funds of Quantum
legally available for payment of dividends on the DLT & Storage Systems group
stock.

   The Board may at any time, in its sole discretion and without stockholder
approval, determine to convert the tracking stock related to one group into the
tracking stock related to the other group at a 10% premium during the first
five years following the implementation of the tracking stock proposal and
without any premium thereafter. The Board may also effect such a conversion at
no premium if, based on the legal opinion of Quantum's tax counsel, it is more
likely than not that for United States federal income tax purposes (i) Quantum
or its stockholders are, or at any time in the future will be, subject to tax
upon the issuance of shares of either DLT & Storage Systems group stock or Hard
Disk Drive group stock, or (ii) either DLT & Storage Systems group stock or
Hard Disk Drive group stock is not, or at any time in the future will not be,
treated as stock of Quantum. In the case of certain dispositions of all or
substantially all of the assets of one group, the Board may determine to
convert the tracking stock of such group into the tracking stock of the other
group at a 10% premium during the first five years following the implementation
of the tracking stock proposal and without any premium thereafter. Any
conversion at a premium would dilute the interests in Quantum of the holders of
the class of tracking stock being issued in the conversion. In addition, any
conversion of a class of tracking stock into another class of tracking stock
would preclude holders of both classes of tracking stock from retaining their
investment in a security that is intended to reflect separately the performance
of the relevant group.

The Board may modify or rescind our policies with respect to the allocation of
corporate overhead, taxes, debt, interest and other matters, or may adopt
additional policies in its sole discretion without stockholder approval.

The DLT & Storage Systems group's combined financial statements reflect the
application of the management and allocation policies adopted by the Board to
various corporate activities, as described below.

              NOTES TO COMBINED FINANCIAL STATEMENTS--(Continued)


Financing Activities. Quantum manages most financial activities of the DLT &
Storage Systems group and the Hard Disk Drive group on a centralized basis.
Such financial activities include the investment of surplus cash, the issuance
and repayment of short-term and long-term debt, the issuance and repurchase of
common stock, and the issuance and repurchase of any preferred stock.

At March 31, 1999, $230 million of Quantum's debt was allocated to the DLT &
Storage Systems group and $115 million was allocated to the Hard Disk Drive
group. The Board has adopted the following financing policy that will affect
the combined statements of the DLT & Storage Systems group and the Hard Disk
Drive group: Quantum will allocate its debt between the groups ("pooled debt")
or, if Quantum so determines, in its entirety to a particular group. Quantum
will allocate preferred stock, if issued, in a similar manner.

Cash allocated to one group that is used to repay pooled debt or redeem pooled
preferred stock decreases such group's allocated portion of the pooled debt or
preferred stock. Cash or other property allocated to one group that is
transferred to the other group, if so determined by the Board, decreases the
transferring group's allocated portion of the pooled debt or preferred stock
and, correspondingly, increases the recipient group's allocated portion of the
pooled debt or preferred stock.

Pooled debt bears interest for group financial statement purposes at a rate
equal to the weighted average interest rate of the debt calculated on a
quarterly basis and applied to the average pooled debt balance during the
period. Preferred stock, if issued and if pooled in a manner similar to the
pooled debt, may bear dividends for group financial statement purposes at a
rate based on the weighted average dividend rate of the preferred stock
similarly calculated and applied. Any expense related to increases in pooled
debt or preferred stock is reflected in the weighted average interest or
dividend rate of such pooled debt or preferred stock as a whole.

Debt for a particular financing allocated in its entirety to one group, bears
interest for group financial statement purposes at the rate determined by the
Board. For preferred stock allocated in its entirety to one group, the dividend
cost to that group is determined in a similar manner. If the interest or
dividend cost is higher than Quantum's actual cost, the other group receives a
credit for an amount equal to the difference as compensation for the use of
Quantum's credit capacity. Any expense related to debt or preferred stock that
is allocated in its entirety to a group is allocated in whole to that group.

Cash or other property that Quantum allocated to one group that is transferred
to the other group is, if so determined by the Board, accounted for either as a
short-term loan or as a long-term loan. Short-term loans and, unless Quantum's
board determines otherwise, long-term loans bear interest at a rate equal to
the weighted average interest rate of Quantum's pooled debt. If Quantum does
not have any pooled debt, the Board determines the rate of interest for such
loan. The Board establishes the terms on which long-term loans between the
groups is made, including interest rate if not based on Quantum's weighted
average interest rate, amortization schedule, maturity and redemption terms.

Although Quantum may allocate its debt and preferred stock between groups, the
debt and preferred stock remain obligations of Quantum and all stockholders of
Quantum are subject to the risks associated with those obligations.

   Allocation of Support Activities. The DLT & Storage Systems group is charged
for specifically identified costs of certain support activities based upon the
DLT & Storage Systems group's use of such activities. Where determinations
based on use alone were not practical, other methods and criteria were used to
provide a reasonable allocation of the cost of support activities attributable
to the DLT & Storage Systems group. Such allocated support activities included
certain selling and marketing, executive management, human resources, corporate
finance, legal and corporate planning costs. The total of these allocations
were $14 million, $28 million, and $30 million in fiscal years 1997, 1998 and
1999, respectively. It is not practicable to provide a detailed estimate of the
expenses which would be recognized if the DLT & Storage Systems group were a
separate entity.

              NOTES TO COMBINED FINANCIAL STATEMENTS--(Continued)


   Allocation of Federal and State Income Taxes. The federal income taxes of
Quantum and the subsidiaries which own assets allocated between the groups are
determined on a consolidated basis. Consolidated federal income tax provisions
and related tax payments or refunds are allocated between the groups based
principally on the taxable income and tax credits directly attributable to each
group, as if each group were a stand-alone entity. Such allocations reflect
each group's contribution (whether positive or negative) to Quantum's
consolidated federal taxable income and the consolidated federal tax liability
and tax credit position. Tax benefits that cannot be used by the group
generating those benefits but can be used on a consolidated basis are credited
to the group that generated such benefits. Accordingly, the amounts of taxes
payable or refundable allocated to each group may not necessarily be the same
as that which would have been payable or refundable had each group filed a
separate income tax return.

Depending on the tax laws of the respective jurisdictions, state and local
income taxes are calculated on either a consolidated or combined basis or on a
separate corporation basis. State income tax provisions and related tax
payments or refunds determined on a consolidated or combined basis are
allocated between the groups based on their respective contributions to such
consolidated or combined state taxable incomes. State and local income tax
provisions and related tax payments which are determined on a separate
corporation basis are allocated between the groups in a manner designed to
reflect the respective contributions of the groups to the corporation's
separate state or local taxable income.

The discussion of the DLT & Storage Systems group's income tax provision (Note
11) should be read in conjunction with Quantum's consolidated financial
statements and notes thereto.

Use of Estimates. The preparation of the financial statements in conformity
with generally accepted accounting principles requires management to make
estimates and assumptions that affect the reported amount of assets and
liabilities at the date of the financial statements and the reported amount of
revenues and expenses during the period. Actual results may differ from the
estimates and assumptions used in preparing the combined financial statements.

Revenue Recognition. Revenue from sales of products is recognized on shipment
to customers, with provision made for estimated returns. The DLT & Storage
Systems group accrues royalty revenue based on licensees' sales that
incorporate certain licensed technology.

Foreign Currency Transactions. Assets, liabilities, and operations of foreign
offices and subsidiaries are recorded based on the functional currency of the
entity. For a majority of the DLT & Storage Systems group's material foreign
operations, the functional currency is the U.S. Dollar. In addition, a majority
of the DLT & Storage Systems group's material transactions are denominated in
U.S. dollars. Accordingly, transaction gains or losses have been immaterial to
the financial statements for all years presented. The effect of foreign
currency exchange rate fluctuations on cash was also immaterial for the years
presented. Assets and liabilities denominated in other than the functional
currency are remeasured each month with the remeasurement gain or loss recorded
in other income.

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

                          DLT & STORAGE SYSTEMS GROUP

              NOTES TO COMBINED FINANCIAL STATEMENTS--(Continued)


   Cash Equivalents. Highly liquid debt instruments with a maturity of 90 days
or less at the time of purchase are considered to be cash equivalents. Cash
equivalents are carried at fair value, which approximates cost. Marketable
securities have maturities of more than 90 days at the time of purchase. Cash
equivalents and marketable securities have been classified as available-for-
sale. Securities classified as available-for-sale are carried at fair value
with material unrealized gains and losses reported in group equity. The cost of
debt securities is adjusted for amortization of premiums and accretion of
discounts to maturity. Such amortization is included in interest income.
Realized gains and losses and declines in value judged to be other-than-
temporary are recorded in other income or expense. The cost of securities sold
is based on the specific identification method.

Concentration of Credit Risk. Quantum performs ongoing credit evaluations of
its customers' financial condition and generally requires no collateral from
its customers. Reserves are maintained for potential credit losses and such
losses have historically been within management's expectations.

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

Investments. Investments in entities (less-than-20-percent-owned companies)
that are not represented by marketable securities are carried at cost less
write-downs for declines in value that are judged to be other-than-temporary.
These valuation losses are recorded in other income when identified. Dividends
are recorded in other income when received.

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

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

Acquired Intangibles. Goodwill and other acquired intangible assets are being
amortized over their estimated useful lives, which range from two to fifteen
years. The accumulated amortization at March 31, 1998 and 1999 was $17 million
and $13 million, respectively. Intangible assets are reviewed for impairment
whenever events or circumstances indicate impairment might exist, or at least
annually.

              NOTES TO COMBINED FINANCIAL STATEMENTS--(Continued)


Warranty Expense. The DLT & Storage Systems group generally warrants its
products against defects for a period of one to three years. A provision for
estimated future costs relating to warranty expense is recorded when products
are shipped and revenue recognized.

Advertising Expense. The DLT & Storage Systems group accrues for co-operative
advertising as the related revenue is earned, and other advertising expense is
recorded as incurred. Advertising expense for the years ended March 31, 1997,
1998 and 1999, was $11 million, $15 million, and $26 million, respectively.

Stock-Based Compensation. The DLT & Storage Systems group accounts for its
stock-based employee compensation plans in accordance with the provisions of
Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to
Employees" and related Interpretations ("APB Opinion No. 25").

Risks and Uncertainties. As is typical in the information storage industry, a
significant portion of the DLT & Storage Systems group's customer base is
concentrated with a small number of OEMs, and the DLT & Storage Systems group
is not able to predict whether there will be any significant change in the
demand for its customers' products. The loss of any one of the DLT & Storage
Systems group's more significant customers could have a material adverse effect
on the DLT & Storage Systems group's results of operations. A limited number of
tape drive storage products make up a significant majority of the DLT & Storage
Systems group's sales, and due to increasingly rapid technological change in
the industry, the DLT & Storage Systems group's future depends on its ability
to develop and successfully introduce new products.

Comprehensive Income. In June 1997, the FASB released Statement of Financial
Accounting Standards No. 130, "Reporting Comprehensive Income." SFAS 130
establishes standards for the reporting and display of comprehensive income and
its components in a full set of general purpose financial statements and has
been implemented by the DLT & Storage Systems group. For all periods presented
comprehensive income equaled net income.

Segment Information. In June 1997, The FASB released Statement of Financial
Accounting Standards No. 131, "Disclosure about Segments of an Enterprise and
Related Information." SFAS 131 changes the way companies report selected
segment information in annual financial statements and also requires companies
to report selected segment information in interim financial reports to
stockholders. SFAS 131 has been implemented by the DLT & Storage Systems group.

Note 2 Financial Instruments

 Available-For-Sale Securities

Quantum's cash and cash equivalents, including certain available-for-sale
securities, are allocated between the DLT & Storage Systems group and the Hard
Disk Drive group. However, marketable securities have been allocated to the
Hard Disk Drive group.

   The difference between the amortized cost of available-for-sale securities
and fair value was immaterial at March 31, 1998 and 1999, and therefore no
gross unrealized gains or losses were recorded in Quantum's stockholders'
equity. The estimated fair value of available-for-sale securities is based on
market quotations. There were no sales of available-for-sale securities in
fiscal years 1998 or 1999. At March 31, 1999, the average available-for-sale
portfolio duration was approximately 20 days, and no security had a maturity
longer than one year.

 Derivative Financial Instruments

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


 Carrying Amount and Fair Values of Financial Instruments

The estimated fair value of Quantum's borrowings (pooled debt) are summarized
as follows:

Note 5 Business Combination

On September 28, 1998, Quantum completed the acquisition of ATL. ATL designs,
manufactures, markets and services automated tape libraries for the networked
computer market. ATL's products incorporate DLTtape drives as well as ATL's
proprietary IntelliGrip automation technology. The acquisition has been
accounted for as a purchase with a total cost of $335 million. The acquisition
was completed with the issuance of 16.9 million shares of Quantum common stock
valued at $265 million on the date of acquisition in exchange for all
outstanding shares of ATL, the conversion of outstanding ATL stock options into
options valued at $22 million to purchase 1.8 million shares of Quantum common
stock and the assumption of $45 million of ATL liabilities. The DLT & Storage
Systems group also recognized deferred tax liabilities of $33 million. ATL's
results of operations are included in the financial statements from the date of
acquisition, and the assets and liabilities acquired were recorded based on
their fair values as of the date of acquisition.

The excess of the purchase price over the fair value of the net tangible assets
acquired has been allocated to the following identifiable intangible assets:
goodwill, trademarks and trade names, original equipment manufacturer and value
added reseller customer relationships, non-compete agreements, workforce in
place, developed technology and in-process research and development. As of the
acquisition date, technological feasibility of the in-process technology has
not been established, and the technology has no alternative future use.
Therefore, the

<PAGE>

                          DLT & STORAGE SYSTEMS GROUP

              NOTES TO COMBINED FINANCIAL STATEMENTS--(Continued)

DLT & Storage Systems group has expensed $89 million of the purchase price as
in-process research and development. The remaining identifiable intangible
assets will be amortized on a straight-line basis over periods ranging from two
to fifteen years.

The amount of the purchase price allocated to in-process research and
development was determined by estimating the stage of development of each in-
process research and development project at the date of acquisition, estimating
cash flows resulting from the expected revenue generated from such projects,
and discounting the net cash flows back to their present value using a discount
rate of 20%, which represents a premium to Quantum's cost of capital. The
expected revenue assumes an average compound annual revenue growth rate of 37%
during fiscal years 1999 to 2007. Expected total revenues from the purchased
in-process projects peak in fiscal year 2002 and then begin to decline as other
new products are expected to be introduced. These projections were based on
management's estimates of market size and growth, expected trends in technology
and the expected timing of new product introductions. If products are not
successfully developed, the DLT & Storage Systems group may not realize the
value assigned to the in-process research and development projects. In
addition, the value of the other acquired intangible assets may also become
impaired.

The following unaudited pro forma information has been prepared assuming that
the acquisition had taken place at the beginning of fiscal year 1998. The pro
forma financial information is not necessarily indicative of the combined
results that would have occurred had the acquisition taken place at the
beginning of the periods, nor is it necessarily indicative of results that may
occur in the future.

              NOTES TO COMBINED FINANCIAL STATEMENTS--(Continued)


In June 1997, Quantum entered into an unsecured senior credit facility that
provides a $500 million revolving credit line and expires in June 2000. At the
option of Quantum, borrowings under the revolving credit line bear interest at
either LIBOR plus a margin determined by a total funded debt ratio, or a base
rate, with option periods of one to six months. As of March 31, 1998 and March
31, 1999, there was no outstanding balance drawn on this line.

In July 1997, Quantum issued $288 million of 7% convertible subordinated notes.
The notes mature on August 1, 2004, and are convertible at the option of the
holder at any time prior to maturity, unless previously redeemed, into shares
of Quantum common stock at a conversion price of $46.325 per share. The notes
are redeemable at Quantum's option on or after August 1, 1999, and prior to
August 1, 2001, under certain conditions related to the price of Quantum common
stock. Subsequent to August 1, 2001, the notes are redeemable at Quantum's
option at any time. In the event of certain changes involving all or
substantially all of Quantum common stock, the notes would become redeemable at
the option of the holder. Redemption prices range from 107% of the principal to
100% at maturity. The notes are unsecured obligations subordinated in right of
payment to all existing and future senior indebtedness of Quantum.

If the tracking stock proposal is implemented, each of the 7% subordinated
notes, which currently are convertible into shares of Quantum common stock,
will become convertible into a number of shares of DLT & Storage Systems group
stock and a number of shares of Hard Disk Drive group stock equal to the
numbers of such shares which the holder of such note would receive under the
tracking stock proposal had such note been converted immediately prior to the
implementation of the tracking stock proposal. The notes will not be separately
convertible into solely DLT & Storage Systems group stock or solely Hard Disk
Drive group stock. The exercise price and maturity date of each convertible
note will not be affected by the implementation of the tracking stock proposal.

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

Payments required on Quantum's long-term debt outstanding at March 31, 1999,
are $1.0 million in fiscal year 2000, $1.1 million in fiscal year 2001, $1.2
million in fiscal year 2002, $1.3 million in fiscal year 2003 and $1.5 million
in fiscal year 2004.

In December 1998, ATL entered into a senior credit facility that provides a $35
million revolving credit line to ATL. The revolving credit line is co-terminous
with Quantum's $500 million revolving credit line, expiring in June 2000. At
the option of ATL, borrowings under the revolving credit line bear interest at
either LIBOR plus a margin determined by a total funded debt ratio of Quantum,
or a base rate, with option periods of one to six months. At March 31, 1999,
$18 million was outstanding on ATL's revolving credit line.

Note 7 Redeemable Preferred Stock

In fiscal year 1998, the holder of the 90,000 shares of Redeemable Convertible
Participating Series B Preferred Stock exercised its right to convert the
shares to Quantum common stock. Quantum issued 180,000 shares of Quantum common
stock pursuant to the conversion.

Note 8 Stock Incentive Plans

Long-Term Incentive Plan. Quantum has a Long-Term Incentive Plan (the "Plan")
that provides for the issuance of stock options, stock appreciation rights,
stock purchase rights, and long-term performance

awards (collectively referred to as "options") to employees, consultants,
officers and affiliates of Quantum. The Plan has available and reserved for
future issuance 19.2 million shares and allows for an annual increase in the
number of shares available for issuance, subject to a limitation. Available for
grant as of March 31, 1999, were 529,000 shares. Options under the Plan expire
no later than ten years from the grant date and generally vest over four years.
Restricted stock granted under the Plan generally vests over two to three
years. In fiscal years 1997, 1998 and 1999, Quantum recorded compensation
expense of $1,916,000, $3,179,000 and $3,211,000, respectively, related to
restricted stock granted pursuant to stock purchase rights under the Plan, a
portion of which was allocated to the DLT & Storage Systems group. The number
of shares of restricted stock granted under the Plan were 354,290 shares,
65,500 shares, and 157,200 shares, in fiscal years 1997, 1998 and 1999,
respectively, at an exercise price of $.01.

   If the tracking stock proposal is approved by the stockholders and
implemented by the Board, each share of restricted stock currently held will be
changed into one share of DLT & Storage Systems group stock and 0.5 of a share
of Hard Disk Drive group stock.

Stock Option Plans. Quantum has Stock Option Plans (the "Plans") under which
5.1 million shares of Quantum common stock was reserved for future issuance at
March 31, 1999 to employees, officers and directors of Quantum. Options under
the Plans are granted at prices determined by the Board, but at not less than
the fair market value, and accordingly no compensation accounting has been
required at the original date of grant. Options currently expire no later than
ten years from the grant date and generally vest ratably over one to four
years. At March 31, 1999, options with respect to 470,000 shares of Quantum
common stock were available for grant.

   Expiration dates ranged from May 8, 1999 to May 1, 2009 for options
outstanding at March 31, 1999. Prices for options exercised during the three-
year period ended March 31, 1999, ranged from $0.01 to $23.94. Proceeds
received from exercises are credited to group equity.

   Completing the acquisition of ATL included the conversion of outstanding ATL
stock options into options to purchase 1.8 million shares of Quantum common
stock. These options relate to Quantum's assumption of ATL's 1996 Stock
Incentive Plan and 1997 Stock Incentive Plan, collectively referred to as the
"ATL Plans." Under the terms of the ATL Plans, eligible key employees,
directors and consultants received options to purchase shares of ATL's
previously outstanding common stock at prices not less than 100% for incentive
stock options and not less than 85% for nonqualified stock options of the fair
value on the date of grant as determined by ATL's Board of Directors. Options
under ATL Plans vest over a three year period and expire ten years after date
of grant or 90 days after termination of employment. Subsequent to completing
the acquisition of ATL, no additional grants may be made from the ATL Plans.
See Note 5 for more information on the acquisition of ATL.

If the tracking stock proposal is approved by the stockholders and implemented
by the Board, each outstanding stock option under Quantum's stock option plans
will be converted into separately exercisable options to acquire one share of
DLT & Storage Systems group stock and 0.5 of a share of Hard Disk Drive group
stock. The exercise price for the resulting DLT & Storage Systems group stock
options and Hard Disk Drive group stock options will be calculated by
multiplying the exercise price under the original option from which they were
converted by a fraction, the numerator of which is the opening price of DLT &
Storage Systems group stock or Hard Disk Drive group stock, as the case may be,
on the first date such stock are traded on New York Stock Exchange and the
denominator of which is the sum of such DLT & Storage Systems group stock and
Hard Disk Drive group stock prices. This is intended to ensure that the
aggregate intrinsic value of the options will be preserved, and the ratio of
the exercise price per option to the market value per share will not be
reduced. In addition, the vesting provision and option periods of the original
grants will remain the same when converted.

   Stock Purchase Plan. Quantum has an employee stock purchase plan (the
"Purchase Plan") that allows for the purchase of stock at 85% of fair market
value at the date of grant or the exercise date, whichever value is less. The
Purchase Plan is qualified under Section 423 of the Internal Revenue Code. Of
the 22.8 million

                          DLT & STORAGE SYSTEMS GROUP

              NOTES TO COMBINED FINANCIAL STATEMENTS--(Continued)

shares authorized to be issued under the plan, 1,366,000 shares were available
for issuance at March 31, 1999. Quantum's employees purchased 3,216,000 shares,
3,454,000 shares, and 2,555,000 shares under the Purchase Plan in fiscal years
1997, 1998, and 1999, respectively. The weighted average exercise price of
stock purchased under the Purchase Plan was $5.41, $6.22 and $9.41 in fiscal
years 1997, 1998, and 1999, respectively.

If the tracking stock proposal is approved by the stockholders and implemented
by the Board, the terms of the Purchase Plan will be adjusted to allow
Quantum's employees to purchase one share of DLT & Storage Systems group stock
and 0.5 of a share of Hard Disk Drive group stock for each share of Quantum
common stock.

Other. The DLT & Storage Systems group adopted SFAS No. 123, "Accounting for
Stock-Based Compensation" in fiscal year 1997. The DLT & Storage Systems group
has elected to continue to account for its stock-based compensation plans under
Accounting Principles Board ("APB") Opinion No. 25 and disclose the pro forma
effects of the plans on net income and earnings per share as provided by SFAS
No. 123. Accordingly, no compensation expense has been recognized for the stock
option plans and the employee stock purchase plans as all options have been
issued at fair market value. Since DLT & Storage Systems group stock was not
part of the capital structure of Quantum for the periods presented, there were
no stock options outstanding. Therefore, the pro forma effect of DLT & Storage
Systems group stock options on the accompanying combined financial statements
is not presented.

Note 9 Common Stock and Stockholder Rights Plan

The DLT & Storage Systems group stock will represent a separate class of
Quantum's stock if the tracking stock proposal is approved. Additional shares
of DLT & Storage Systems group stock may be issued from time to time upon
exercise of stock options or at the discretion of Quantum's Board.

Quantum has a stockholder rights plan (the "Rights Plan") that provides
existing stockholders with the right to purchase 1/1000 preferred share for
each common share held in the event of certain changes in Quantum's ownership.
Subject to certain exceptions, if any person or group becomes the beneficial
owner of 20% or more of the outstanding common stock each right will entitle
its holder to purchase 1/1,000 preferred share or, under certain circumstances,
shares of common stock with a market value twice the exercise price of the
right. The Rights Plan may serve as a deterrent to takeover tactics that are
not in the best interests of stockholders. There are 1,000,000 preferred shares
reserved for issuance under the Rights Plan.

If the tracking stock proposal is approved by the stockholders and implemented
by the Board, the Rights Agreement will be amended and restated (the "Restated
Rights Agreement") to, among other things, (i) reflect the new equity structure
of Quantum and (ii) reset the prices at which rights issued pursuant thereto
may be exercised into units of Junior Preferred Stock.

If the tracking stock proposal is approved by the stockholders and implemented
by the Board, as of the date on which the DLT & Storage Systems group stock and
the Hard Disk Drive group stock is issued under the tracking stock proposal,
the Board will by resolution (i) reduce the authorized number of shares of
Series A Junior Preferred Stock to zero, (ii) designate a new series of Junior
Preferred Stock as the Series B Junior Preferred Stock, (iii) designate another
new series of Junior Preferred Stock as the Series C Junior Preferred Stock,
(iv) exchange for each existing Right (A) one right with respect to each share
of DLT & Storage Systems group stock (a "DLT & Storage Systems group right")
which will entitle the holders thereof to purchase shares of Series B Junior
Preferred Stock under the conditions specified in the Restated Rights
Agreement, and (B) one right with respect to each share of Hard Disk Drive
group stock (a "Hard Disk

                                      F-19

              NOTES TO COMBINED FINANCIAL STATEMENTS--(Continued)

Drive group right"), which will entitle the holders thereof to purchase shares
of Series C Junior Preferred Stock under the conditions specified in the
Restated Rights Agreement. The DLT & Storage Systems group rights and the Hard
Disk Drive group rights are herein collectively referred to as the "rights."

The rights will expire on August 4, 2008, unless earlier redeemed by Quantum or
extended. The rights would be exercisable only if a person or group acquires
(i) 20% or more of the then outstanding shares of DLT & Storage Systems group
stock or (ii) 20% of the then outstanding shares of Hard Disk Drive group
stock, or commences a tender offer that would result in such person or group
beneficially owning such number of shares. In such event and subject to certain
exceptions, each right would entitle the holder to purchase from Quantum (i) in
the case of a DLT & Storage Systems group right, 1/1000 of a share of Series B
Junior Preferred Stock (a "Series B Unit") at a purchase price to be determined
by the Board, subject to adjustment or, under certain circumstances, shares of
DLT & Storage Systems group stock with a market value twice the exercise price
of the DLT & Storage Systems group right and (ii) in the case of a Hard Disk
Drive group right, 1/1000 of a share of Series C Junior Preferred Stock (a
"Series C Unit") at a purchase price to be determined by the Board, subject to
adjustment or, under certain circumstances, shares of Hard Disk Drive group
stock with a market value twice the exercise price of the Hard Disk Drive group
right.

Note 10 Savings and Investment Plan

Substantially all of the regular domestic employees are eligible to make
contributions to Quantum's 401(k) savings and investment plan. Quantum matches
a percentage of the employees' contributions and may also make additional
discretionary contributions to the plan. Quantum contributions were $5 million,
$6 million and $7 million in fiscal years 1997, 1998 and 1999, respectively.

Quantum's federal income tax returns have been examined by the Internal Revenue
Service (IRS) for all years through 1993. All issues have been resolved with no
material effect, and the IRS has closed those years. Quantum's federal income
tax returns for the years 1995-1996 are presently under examination by the IRS.
Management believes sufficient accruals have been provided in prior years for
any adjustments that may result for the years under examination.

per $1000 note, because the effect would have been antidilutive.

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS

To the Board of Directors and Stockholders of Quantum Corporation

We have audited the accompanying combined balance sheets of the Hard Disk Drive
group (as described in Note 1) of Quantum Corporation as of March 31,1998 and
1999 and the related combined statements of operations, group equity, and cash
flows for each of the three years in the period ended March 31, 1999. These
financial statements are the responsibility of Quantum Corporation's
management. Our responsibility is to express an opinion on these financial
statements based on our audits. We did not audit the consolidated financial
statements of MKE-Quantum Components LLC ("MKQC"), a forty-nine percent equity
investee of the Hard Disk Drive group, which statements reflect a net loss of
$134.8 million for the period from May 16, 1997 (inception) through March 31,
1998. Those statements were audited by other auditors whose report has been
furnished to us, and our opinion, insofar as it relates to data included for
MKQC, is based solely on the report of the other auditors.

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 and the report of other
auditors provide a reasonable basis for our opinion.

In our opinion, based on our audits and the report of other auditors, the
financial statements referred to above present fairly, in all material
respects, the financial position of the Hard Disk Drive group at March 31, 1998
and 1999 and the results of its operations and its cash flows for each of the
three years in the period ended March 31, 1999, in conformity with generally
accepted accounting principles.

As more fully described in Note 1 to these financial statements, the Hard Disk
Drive group is a business group of Quantum Corporation; accordingly, the
combined financial statements of the Hard Disk Drive group should be read in
conjunction with the audited consolidated financial statements of Quantum
Corporation.

We conducted our audit in accordance with generally accepted auditing

                             HARD DISK DRIVE GROUP

                     NOTES TO COMBINED FINANCIAL STATEMENTS

The accompanying combined financial statements should be read in conjunction
with the consolidated financial statements of Quantum Corporation ("Quantum").

Note 1 Summary of Significant Accounting Policies

Nature of Business. Quantum operates its business through two separate groups:
the Hard Disk Drive group and the DLT & Storage Systems group as described
below. The Hard Disk Drive group and the DLT & Storage Systems group are
referred to as the "groups."

The Hard Disk Drive group designs desktop hard disk drives to meet the storage
requirements of entry-level to high-end desktop PCs in home and business
environments. The Hard Disk Drive group also designs high-end hard disk drives
for the demanding storage needs of network servers, workstations and storage
sub-systems.

The DLT & Storage Systems group designs, develops, manufactures, licenses and
markets DLTtape drives and media, tape libraries and solid state storage
systems. DLTtape is the DLT & Storage Systems group's half-inch tape technology
that is the de facto industry standard for data backup in the mid-range server
market.

The Board of Directors (the "Board") of Quantum has recommended stockholder
approval of a proposal that would create two classes of tracking stock intended
to reflect separately the performance of the Hard Disk Drive group and the DLT
& Storage Systems group. Under the tracking stock proposal, Quantum's
Certificate of Incorporation would be amended and restated (the "Restated
Certificate of Incorporation") to (i) designate a new class of Quantum
Corporation--the Hard Disk Drive group Common Stock, $.01 par value per share,
(ii) designate a new class of Quantum Corporation--DSSG Common Stock, $.01 par
value per share, and (iii) reclassify each authorized share of existing common
stock, $.01 par value per share as one-half share of Hard Disk Drive group
stock and one share of DLT & Storage Systems group stock.

The combined financial statements of the groups comprise all of the accounts
included in the corresponding consolidated financial statements of Quantum. The
separate group combined financial statements give effect to the accounting
policies that will be applicable upon implementation of the tracking stock
proposal. The separate the Hard Disk Drive group and the DLT & Storage Systems
group financial statements have been prepared on a basis that management
believes to be reasonable and appropriate and include (i) the historical
balance sheets, results of operations, and cash flows of businesses that
comprise each of the groups, with all significant intragroup transactions and
balances eliminated, (ii) in the case of the Hard Disk Drive group's financial
statements, corporate assets and liabilities of Quantum and related
transactions identified with the Hard Disk Drive group, including allocated
portions of Quantum's debt and selling, general and administrative costs, and
(iii) in the case of the DLT & Storage Systems group's financial statements,
corporate assets and liabilities of Quantum and related transactions identified
with the DLT & Storage Systems group, including allocated portions of Quantum's
debt and selling, general and administrative costs.

   Holders of the Hard Disk Drive group stock and DLT & Storage Systems group
stock will be stockholders of a single company. The Hard Disk Drive group and
the DLT & Storage Systems group are not separate legal entities. As a result,
stockholders will continue to be subject to all of the risks of an investment
in Quantum and all of Quantum's business, assets and liabilities. The issuance
of Hard Disk Drive group stock and DLT & Storage Systems group stock and the
allocation of assets or liabilities and stockholders' equity between the Hard
Disk Drive group and the DLT & Storage Systems group will not result in a
distribution or spin-off to stockholders of any of Quantum's assets or
liabilities and will not affect ownership of any of Quantum's assets or
responsibility for Quantum's liabilities or those of Quantum's subsidiaries.
The assets Quantum attributes to one group could be subject to the liabilities
of the other group. If Quantum is unable to satisfy one group's liabilities out
of the assets attributed to it, Quantum may be required to satisfy those
liabilities with assets Quantum has

                   QUANTUM CORPORATION--HARD DISK DRIVE GROUP

              NOTES TO COMBINED FINANCIAL STATEMENTS--(Continued)

attributed to the other group. Holders of Hard Disk Drive group stock and DLT &
Storage Systems group stock generally will not have stockholder rights specific
to their corresponding group. Instead, holders have customary rights relating
to Quantum as a whole. Holders of tracking stock will not have any rights
related to their corresponding group except as set forth in provisions relating
to dividend rights and requirements for a mandatory dividend, redemption or
conversion upon the disposition of all or substantially all of the assets of
their corresponding group, or have any right to vote on matters as a separate
voting group other than in limited circumstances as provided under Delaware law
or by New York Stock Exchange rules. The relative voting power of Hard Disk
Drive group stock and DLT & Storage Systems group stock will fluctuate from
time to time, with each share of DLT & Storage Systems group stock having one
vote and each share of Hard Disk Drive group stock having a number of votes,
based upon the ratio, over a specified period, of the average market values of
one share of Hard Disk Drive group stock and of one share of DLT & Storage
Systems group stock. This formula is intended to give each class of tracking
stock a number of votes proportionate to its aggregate market capitalization at
the time of any vote. Accordingly, changes in the market value of Hard Disk
Drive group stock and DLT & Storage Systems group stock will affect the
relative voting rights of a class of tracking stock. It is expected that
initially the holders of DLT & Storage Systems group stock will have a
substantial majority of the voting power of Quantum.

   Financial effects arising from one group that affect Quantum's consolidated
results of operations or financial condition could, if significant, affect the
results of operations or financial condition of the other group and the market
price of the class of tracking stock relating to the other group. Any net
losses of the Hard Disk Drive group or the DLT & Storage Systems group and
dividends or distributions on, or repurchases of, Hard Disk Drive group stock
or DLT & Storage Systems group stock, or repurchases of preferred stock at a
price per share greater than par value, will reduce the funds of Quantum
legally available for payment of dividends on the Hard Disk Drive group stock.

The Board may at any time, in its sole discretion and without stockholder
approval, determine to convert the tracking stock related to one group into the
tracking stock related to the other group at a 10% premium during the first
five years following the implementation of the tracking stock proposal and
without any premium thereafter. The Board may also effect such a conversion at
no premium if, based on the legal opinion of Quantum's tax counsel, it is more
likely than not that for United States federal income tax purposes (i) Quantum
or its stockholders are, or at any time in the future will be, subject to tax
upon the issuance of shares of either Hard Disk Drive group stock or DLT &
Storage Systems group stock, or (ii) either Hard Disk Drive group stock or DLT
& Storage Systems group stock is not, or at any time in the future will not be,
treated as stock of Quantum. In the case of certain dispositions of all or
substantially all of the assets of one group, the Board may determine to
convert the tracking stock of such group into the tracking stock of the other
group at a 10% premium during the first five years following the implementation
of the tracking stock proposal and without any premium thereafter. Any
conversion at a premium would dilute the interests in Quantum of the holders of
the class of tracking stock being issued in the conversion. In addition, any
conversion of a class of tracking stock into another class of tracking stock
would preclude holders of both classes of tracking stock from retaining their
investment in a security that is intended to reflect separately the performance
of the relevant group.

   The Board may modify or rescind our policies with respect to the allocation
of corporate overhead, taxes, debt, interest and other matters, or may adopt
additional policies in its sole discretion without stockholder approval.

The Hard Disk Drive group's combined financial statements reflect the
application of the management and allocation policies adopted by the Board to
various corporate activities, as described below.

                             HARD DISK DRIVE GROUP

              NOTES TO COMBINED FINANCIAL STATEMENTS--(Continued)


Financing Activities. Quantum manages most financial activities of the Hard
Disk Drive group and the DLT & Storage Systems group on a centralized basis.
Such financial activities include the investment of surplus cash, the issuance
and repayment of short-term and long-term debt, the issuance and repurchase of
common stock, and the issuance and repurchase of any preferred stock.

At March 31, 1999, $115 million of Quantum's debt was allocated to the Hard
Disk Drive group and $230 million was allocated to the DLT & Storage Systems
group. The Board has adopted the following financing policy that will affect
the combined statements of the Hard Disk Drive group and the DLT & Storage
Systems group: Quantum will allocate its debt between the groups ("pooled
debt") or, if Quantum so determines, in its entirety to a particular group.
Quantum will allocate preferred stock, if issued, in a similar manner.

Cash allocated to one group that is used to repay pooled debt or redeem pooled
preferred stock decreases such group's allocated portion of the pooled debt or
preferred stock. Cash or other property allocated to one group that is
transferred to the other group, if so determined by the Board, decreases the
transferring group's allocated portion of the pooled debt or preferred stock
and, correspondingly, increases the recipient group's allocated portion of the
pooled debt or preferred stock.

   Pooled debt bears interest for group financial statement purposes at a rate
equal to the weighted average interest rate of the debt calculated on a
quarterly basis and applied to the average pooled debt balance during the
period. Preferred stock, if issued and if pooled in a manner similar to the
pooled debt, may bear dividends for group financial statement purposes at a
rate based on the weighted average dividend rate of the preferred stock
similarly calculated and applied. Any expense related to increases in pooled
debt or preferred stock is reflected in the weighted average interest or
dividend rate of such pooled debt or preferred stock as a whole.

Debt for a particular financing allocated in its entirety to one group, bears
interest for group financial statement purposes at the rate determined by the
Board. For preferred stock allocated in its entirety to one group the dividend
cost to that group is determined in a similar manner. If the interest or
dividend cost is higher than Quantum's actual cost, the other group receives a
credit for an amount equal to the difference as compensation for the use of
Quantum's credit capacity. Any expense related to debt or preferred stock that
is allocated in its entirety to a group is allocated in whole to that group.

Cash or other property that Quantum allocated to one group that is transferred
to the other group is, if so determined by the Board, accounted for either as a
short-term loan or as a long-term loan. Short-term loans and, unless Quantum's
board determines otherwise, long-term loans bear interest at a rate equal to
the weighted average interest rate of Quantum's pooled debt. If Quantum does
not have any pooled debt, the Board determines the rate of interest for such
loan. The Board establishes the terms on which long-term loans between the
groups is made, including interest rate if not based on Quantum's weighted
average interest rate, amortization schedule, maturity and redemption terms.

Although Quantum may allocate its debt and preferred stock between groups, the
debt and preferred stock remain obligations of Quantum and all stockholders of
Quantum are subject to the risks associated with those obligations.

Allocation of Support Activities. The Hard Disk Drive group is charged for
specifically identified costs of certain support activities based upon the Hard
Disk Drive group's use of such activities. Where determinations based on use
alone were not practical, other methods and criteria were used to provide a
reasonable allocation of the cost of support activities attributable to the
Hard Disk Drive group. Such allocated support activities included certain
selling and marketing, executive management, human resources, corporate
finance, legal and corporate planning costs. The total of these allocations
were $98 million, $79 million, and $70 million in fiscal years 1997, 1998 and
1999, respectively. It is not practicable to provide a detailed estimate of the
expenses which would be recognized if the Hard Disk Drive group were a separate
entity.

              NOTES TO COMBINED FINANCIAL STATEMENTS--(Continued)


Allocation of Federal and State Income Taxes. The federal income taxes of
Quantum and the subsidiaries which own assets allocated between the groups are
determined on a consolidated basis. Consolidated federal income tax provisions
and related tax payments or refunds are allocated between the groups based
principally on the taxable income and tax credits directly attributable to each
group, as if each group were a stand-alone entity. Such allocations reflect
each group's contribution (whether positive or negative) to Quantum's
consolidated federal taxable income and the consolidated federal tax liability
and tax credit position. Tax benefits that cannot be used by the group
generating those benefits but can be used on a consolidated basis are credited
to the group that generated such benefits. Accordingly, the amounts of taxes
payable or refundable allocated to each group may not necessarily be the same
as that which would have been payable or refundable had each group filed a
separate income tax return.

Depending on the tax laws of the respective jurisdictions, state and local
income taxes are calculated on either a consolidated or combined basis or on a
separate corporation basis. State income tax provisions and related tax
payments or refunds are allocated between the groups based on their respective
contributions to such consolidated or combined state taxable incomes. State and
local income tax provisions and related tax payments which are determined on a
separate corporation basis are allocated between the groups in a manner
designed to reflect the respective contributions of the groups to the
corporation's separate state or local taxable income.

The discussion of the Hard Disk Drive group's income tax provision (Note 12)
should be read in conjunction with Quantum's consolidated financial statements
and notes thereto.

Use of Estimates. The preparation of the financial statements in conformity
with generally accepted accounting principles requires management to make
estimates and assumptions that affect the reported amount of assets and
liabilities at the date of the financial statements and the reported amount of
revenues and expenses during the period. Actual results may differ from the
estimates and assumptions used in preparing the combined financial statements.

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

Foreign Currency Translation and Transactions. Assets, liabilities, and
operations of foreign offices and subsidiaries are recorded based on the
functional currency of the entity. For a majority of the Hard Disk Drive
group's material foreign operations, the functional currency is the U.S.
Dollar. The assets and liabilities of foreign offices with a local functional
currency are translated at current exchange rates from the local currency to
the reporting currency, the U.S. Dollar. The resulting gains or losses are
reported as a component of group equity. Although close to half of the Hard
Disk Drive group's sales are made to customers in non-U.S. locations and all of
the Hard Disk Drive group's hard disk drive products are manufactured in Japan,
Singapore and Ireland by Matsushita-Kotobuki Electronics Industries, Ltd.
("MKE"), a majority of the Hard Disk Drive group's material transactions are
denominated in U.S. dollars, including the purchase by the Hard Disk Drive
group of hard disk drives manufactured by MKE in U.S. dollars. Accordingly,
transaction gains or losses have been immaterial to the financial statements
for all years presented. The effect of foreign currency exchange rate
fluctuations on cash was also immaterial for the years presented. Assets and
liabilities denominated in other than the functional currency are remeasured
each month with the remeasurement gain or loss recorded in other income.

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

              NOTES TO COMBINED FINANCIAL STATEMENTS--(Continued)


Cash Equivalents and Marketable Securities. Highly liquid debt instruments with
a maturity of 90 days or less at the time of purchase are considered to be cash
equivalents. Cash equivalents are carried at fair value, which approximates
cost. Marketable securities have maturities of more than 90 days at the time of
purchase. Cash equivalents and marketable securities have been classified as
available-for-sale. Securities classified as available-for-sale are carried at
fair value with material unrealized gains and losses reported in Group equity.
The cost of debt securities is adjusted for amortization of premiums and
accretion of discounts to maturity. Such amortization is included in interest
income. Realized gains and losses and declines in value judged to be other-
than-temporary are recorded in other income or expense. The cost of securities
sold is based on the specific identification method.


Concentration of Credit Risk. Quantum performs ongoing credit evaluations of
its customers' financial condition and generally requires no collateral from
its customers. Reserves are maintained for potential credit losses and such
losses have historically been within management's expectations.

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

Investments in Joint Ventures and Other Entities. Investments in joint ventures
and other entities are recorded in other assets. Investments in joint ventures
are accounted for by the equity method. Dividends are recorded as a reduction
of the carrying value of the investment when received.

Investments in other entities (less-than-20-percent-owned companies) that are
not represented by marketable securities are carried at cost less write-downs
for declines in value that are judged to be other-than-temporary. These
valuation losses are recorded in other income when identified. Dividends are
recorded in other income when received.

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

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

              NOTES TO COMBINED FINANCIAL STATEMENTS--(Continued)


   Acquired Intangibles. Acquired intangible assets are being amortized over
their estimated useful lives, which range from three to five years. The
accumulated amortization at March 31, 1998 and 1999 was $6 million and $5
million, respectively. Intangible assets are reviewed for impairment whenever
events or circumstances indicate impairment might exist, or at least annually.

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

Advertising Expense. The Hard Disk Drive group accrues for co-operative
advertising as the related revenue is earned, and other advertising expense is
recorded as incurred. Advertising expense for the years ended March 31, 1997,
1998 and 1999, was $24 million, $26 million, and $20 million, respectively.

Stock-Based Compensation. The Hard Disk Drive group accounts for its stock-
based employee compensation plans in accordance with the provisions of
Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to
Employees" and related Interpretations ("APB Opinion No. 25").

Risks and Uncertainties. The Hard Disk Drive group's business entails a number
of risks. As is typical in the information storage industry, a significant
portion of the Hard Disk Drive group's customer base is concentrated with a
small number of OEMs, and the Hard Disk Drive group is not able to predict
whether there will be any significant change in the demand for its customers'
products. The loss of any one of the Hard Disk Drive group's more significant
customers could have a material adverse effect on the Hard Disk Drive group's
results of operations. A limited number of hard disk drive storage products
make up a significant majority of the Hard Disk Drive group's sales, and due to
increasingly rapid technological change in the industry, the Hard Disk Drive
group's future depends on its ability to develop and successfully introduce new
products. The Hard Disk Drive group utilizes a third party, MKE, to manufacture
all of the products it sells. The Hard Disk Drive group relies on MKE's ability
to bring new products rapidly to volume production and to meet stringent
quality standards. MKE manufactures the Hard Disk Drive group's drives in
Japan, Singapore, and Ireland. If MKE were unable to satisfy the Hard Disk
Drive group's production requirements, the Hard Disk Drive group would not have
an alternative source to meet the demand for its products without substantial
delay and disruption to its operations.

Comprehensive Income. In June 1997, the FASB released Statement of Financial
Accounting Standards No. 130, "Reporting Comprehensive Income." SFAS 130
establishes standards for the reporting and display of comprehensive income and
its components in a full set of general purpose financial statements and has
been implemented by the Hard Disk Drive group.

Segment Information. In June 1997, The FASB released Statement of Financial
Accounting Standards No. 131, "Disclosure about Segments of an Enterprise and
Related Information." SFAS 131 changes the way companies report selected
segment information in annual financial statements and also requires companies
to report selected segment information in interim financial reports to
stockholders. SFAS 131 has been implemented by the Hard Disk Drive group.

Quantum's cash and cash equivalents, including certain available-for-sale
securities, are allocated between the Hard Disk Drive group and the DLT &
Storage Systems group. However, marketable securities have been allocated to
the Hard Disk Drive group.

</TABLE>

The difference between the amortized cost of available-for-sale securities and
fair value was immaterial at March 31, 1998 and 1999, and therefore no gross
unrealized gains or losses were recorded in Quantum's stockholders' equity. The
estimated fair value of available-for-sale securities is based on market
quotations. There were no sales of available-for-sale securities in fiscal
years 1998 or 1999. At March 31, 1999, the average available-for-sale portfolio
duration was approximately 20 days, and no security had a maturity longer than
one year.

 Derivative Financial Instruments

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

</TABLE>

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

Note 5 Loss from Investee

On May 16, 1997, the Hard Disk Drive group sold a controlling interest in its
recording heads operations to MKE, thereby forming a recording heads joint
venture with MKE, MKE-Quantum Components LLC ("MKQC"). The operations were
involved in the research, development, and manufacture of MR recording heads
used in the Hard Disk Drive group's hard disk drive products manufactured by
MKE.

The Hard Disk Drive group contributed recording heads assets and operations,
and leased certain premises to MKQC. The recording heads assets that Quantum
contributed to MKQC consisted of inventory, equipment, accounts receivable, and
intangibles, which aggregated $211 million. MKQC assumed $51 million of debt
payable to Quantum and assumed $24 million of third-party liabilities. MKE paid
Quantum $94 million and contributed $110 million to MKQC in exchange for a 51%
majority ownership interest in MKQC. Quantum retained a 49% minority ownership
interest in MKQC. Quantum employees who were involved in the recording heads
operations became employees of MKQC.

MKE and Quantum shared pro rata in MKQC's results of operations and agreed to
share pro rata in any capital funding requirements.

Subsequent to May 16, 1997, the Hard Disk Drive group accounted for its 49%
interest in MKQC using the equity method of accounting. The results of the Hard
Disk Drive group's involvement in recording heads through May 15, 1997, were
combined.

Quantum provided support services to MKQC. The support services were mainly
finance, human resources, legal, and computer support. MKQC reimbursed Quantum
for the estimated cost of the services.

On October 28, 1998, Quantum and MKE agreed to dissolve MKQC because MKQC had
not been able to produce MR recording heads on a cost-effective basis. In
connection with the dissolution, MKE has taken control and ownership of MKQC's
manufacturing operations in Batam, Indonesia; MKQC's domestic operations have
ceased; and its domestic assets are in liquidation. In the third quarter of
fiscal year 1999, the Hard Disk Drive group recorded a $101 million loss from
investee (unaudited) which includes a write-off of the Hard Disk Drive group's
investment in MKQC; a write-down of the Hard Disk Drive group's interest in
facilities in Louisville, Colorado, and Shrewsbury, Massachusetts that were
occupied by MKQC; warranty costs resulting from MR recording heads manufactured
by MKQC; and the Hard Disk Drive group's 49% pro rata share in funding MKQC's
repayment of its obligations, primarily bank debt, accounts payable, and other
liabilities through June 1999 when the liquidation of MKQC is expected to be
completed.

MKQC's unaudited net loss for the six months ended September 27, 1998 was $84
million (unaudited) on revenue of $62 million (unaudited). The Hard Disk Drive
group's 49% interest in the net loss was $41 million.

In June 1997, Quantum entered into an unsecured senior credit facility that
provides a $500 million revolving credit line and expires in June 2000. At the
option of Quantum, borrowings under the revolving credit line bear interest at
either LIBOR plus a margin determined by a total funded debt ratio, or a base
rate, with option periods of one to six months. As of March 31, 1998 and March
31, 1999, there was no outstanding balance drawn on this line.

In July 1997, Quantum issued $288 million of 7% convertible subordinated notes.
The notes mature on August 1, 2004, and are convertible at the option of the
holder at any time prior to maturity, unless previously redeemed, into shares
of Quantum's common stock at a conversion price of $46.325 per share. The notes
are redeemable at Quantum's option on or after August 1, 1999, and prior to
August 1, 2001, under certain conditions related to the price of Quantum's
common stock. Subsequent to August 1, 2001, the notes are redeemable at
Quantum's option at any time. In the event of certain changes involving all or
substantially all of Quantum's common stock, the notes would become redeemable
at the option of the holder. Redemption prices range from 107% of the principal
to 100% at maturity. The notes are unsecured obligations subordinated in right
of payment to all existing and future senior indebtedness of Quantum.

If the Tracking Stock Proposal is implemented, each of the 7% subordinated
notes, which currently are convertible into shares of Quantum Common Stock,
will become convertible into a number of shares of Hard Disk Drive group stock
and a number of shares of DLT & Storage Systems group stock equal to the
numbers

of such shares which the holder of such note would receive under the tracking
stock proposal had such note been converted immediately prior to the
implementation of the tracking stock proposal. The notes will not be separately
convertible into solely DLT & Storage Systems group stock or solely Hard Disk
Drive group stock. The exercise price and maturity date of each convertible
note will not be affected by the implementation of the tracking stock proposal.

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

Payments required on Quantum's long-term debt outstanding at March 31, 1999,
are $1.0 million in fiscal year 2000, $1.1 million in fiscal year 2001, $1.2
million in fiscal year 2002, $1.3 million in fiscal year 2003 and $1.5 million
in fiscal year 2004.

Note 7 Redeemable Preferred Stock

In fiscal year 1998, the holder of the 90,000 shares of Redeemable Convertible
Participating Series B Preferred Stock exercised its right to convert the
shares to Quantum common stock. Quantum issued 180,000 shares of Quantum common
stock pursuant to the conversion.

Note 8 Stock Incentive Plans

Long-Term Incentive Plan. Quantum has a Long-Term Incentive Plan (the "Plan")
that provides for the issuance of stock options, stock appreciation rights,
stock purchase rights, and long-term performance awards (collectively referred
to as "options") to employees, consultants, officers and affiliates of Quantum.
The Plan has available and reserved for future issuance 19.2 million shares and
allows for an annual increase in the number of shares available for issuance,
subject to a limitation. Available for grant as of March 31, 1999, were 529,000
shares. Options under the Plan expire no later than ten years from the grant
date and generally vest over four years. Restricted stock granted under the
Plan generally vests over two to three years. In fiscal years 1997, 1998 and
1999, Quantum recorded compensation expense of $1,916,000, $3,179,000 and
$3,211,000, respectively, related to restricted stock granted pursuant to stock
purchase rights under the Plan, a portion of which was allocated to the Hard
Disk Drive group. The number of shares of restricted stock granted under the
Plan were 354,290 shares, 65,500 shares, and 157,200 shares, in fiscal years
1997, 1998 and 1999, respectively, at an exercise price of $.01.

   If the tracking stock proposal is approved by the stockholders and
implemented by the Board, each share of restricted stock currently held will be
changed into one share of DLT & Storage Systems group stock and 0.5 of a share
of Hard Disk Drive group stock.

Stock Option Plans. Quantum has Stock Option Plans (the "Plans") under which
5.1 million shares of Quantum common stock was reserved for future issuance at
March 31, 1999 to directors of Quantum. Options under the Plans are granted at
prices determined by the Board, but at not less than the fair market value, and
accordingly no compensation accounting has been required at the original date
of grant. Options currently expire no later than ten years from the grant date
and generally vest ratably over one to four years. At March 31, 1999, options
with respect to 470,000 shares of Quantum common stock were available for
grant.

   Expiration dates ranged from May 8, 1999 to May 1, 2009 for options
outstanding at March 31, 1999. Prices for options exercised during the three-
year period ended March 31, 1999, ranged from $0.01 to $23.94. Proceeds
received from exercises are credited to group equity.

Completing the acquisition of ATL included the conversion of outstanding ATL
stock options into options to purchase 1.8 million shares of Quantum common
stock. These options relate to Quantum's assumption of ATL's 1996 Stock
Incentive Plan and 1997 Stock Incentive Plan, collectively referred to as the
"ATL Plans." Under the terms of the ATL Plans, eligible key employees,
directors and consultants received options to purchase shares of ATL's
previously outstanding common stock at prices not less than 100% for incentive
stock options and not less than 85% for nonqualified stock options of the fair
value on the date of grant as

              NOTES TO COMBINED FINANCIAL STATEMENTS--(Continued)

determined by ATL's Board of Directors. Options under ATL Plans vest over a
three year period and expire ten years after date of grant or 90 days after
termination of employment. Subsequent to completing the acquisition of ATL, no
additional grants may be made from the ATL Plans.

If the tracking stock proposal is approved by the stockholders and implemented
by the Board, each outstanding stock option under Quantum's stock option plans
will be converted into separately exercisable options to acquire one share of
DLT & Storage Systems group stock and 0.5 of a share of Hard Disk Drive group
stock. The exercise price for the resulting DLT & Storage Systems group stock
options and Hard Disk Drive group stock options will be calculated by
multiplying the exercise price under the original option from which they were
converted by a fraction, the numerator of which is the opening price of DLT &
Storage Systems group stock or Hard Disk Drive group stock, as the case may be,
on the first date such stock are traded on the New York Stock Exchange and the
denominator of which is the sum of such DLT & Storage Systems group stock and
Hard Disk Drive group stock prices. This is intended to ensure that the
aggregate intrinsic value of the options will be preserved, and the ratio of
the exercise price per option to the market value per share will not be
reduced. In addition, the vesting provision and option periods of the original
grants will remain the same when converted.

Stock Purchase Plan. Quantum has an employee stock purchase plan (the "Purchase
Plan") that allows for the purchase of stock at 85% of fair market value at the
date of grant or the exercise date, whichever value is less. The Purchase Plan
is qualified under Section 423 of the Internal Revenue Code. Of the 22.8
million shares authorized to be issued under the plan, 1,366,000 shares were
available for issuance at March 31, 1999. Quantum's employees purchased
3,216,000 shares, 3,454,000 shares, and 2,555,000 shares under the Purchase
Plan in fiscal years 1997, 1998, and 1999, respectively. The weighted average
exercise price of stock purchased under the Purchase Plan was $5.41, $6.22 and
$9.41 in fiscal years 1997, 1998, and 1999, respectively.

If the tracking stock proposal is approved by the stockholders and implemented
by the Board, the terms of the Purchase Plan will be adjusted to allow
Quantum's employees to purchase one share of DLT & Storage Systems group stock
and 0.5 of a share of Hard Disk Drive group stock for each share of Quantum
common stock.

Other. The Hard Disk Drive group adopted SFAS No. 123, "Accounting for Stock-
Based Compensation" in fiscal year 1997. The Hard Disk Drive group has elected
to continue to account for its stock-based compensation plans under Accounting
Principles Board ("APB") Opinion No. 25 and disclose the pro forma effects of
the plans on net income and earnings per share as provided by SFAS No. 123.
Accordingly, no compensation expense has been recognized for the stock option
plans and the employee stock purchase plans as all options have been issued at
fair market value. Since Hard Disk Drive group stock was not part of the
capital structure of Quantum for the periods presented, there were no stock
options outstanding. Therefore, the pro forma effect of Hard Disk Drive group
stock options on the accompanying combined financial statements is not
presented.

Note 9 Common Stock and Stockholder Rights Plan

The Hard Disk Drive group stock will represent a separate class of Quantum's
stock if the tracking stock proposal is approved. Additional shares of Hard
Disk Drive group stock may be issued from time to time upon exercise of stock
options or at the discretion of Quantum's Board.

   Quantum has a stockholder rights plan (the "Rights Plan") that provides
existing stockholders with the right to purchase 1/1000 preferred share for
each common share held in the event of certain changes in Quantum's ownership.
Subject to certain exceptions, if any person or group becomes the beneficial
owner of

              NOTES TO COMBINED FINANCIAL STATEMENTS--(Continued)

20% or more of the outstanding common stock each right will entitle its holder
to purchase 1/1000 preferred share or, under certain circumstances, shares of
common stock with a market value twice the exercise price of the right. The
Rights Plan may serve as a deterrent to takeover tactics that are not in the
best interests of stockholders.

If the tracking stock proposal is approved by the stockholders and implemented
by the Board, the Rights Agreement will be amended and restated (the "Restated
Rights Agreement") to, among other things, (i) reflect the new equity structure
of Quantum and (ii) reset the prices at which rights issued pursuant thereto
may be exercised into units of Junior Preferred Stock.

If the tracking stock proposal is approved by the stockholders and implemented
by the Board, as of the date on which the DLT & Storage Systems group stock and
the Hard Disk Drive group stock is issued under the tracking stock proposal,
the Board will by resolution (i) reduce the authorized number of shares of
Series A Junior Preferred Stock to zero, (ii) designate a new series of Junior
Preferred Stock as the Series B Junior Preferred Stock, (iii) designate another
new series of Junior Preferred Stock as the Series C Junior Preferred Stock,
(iv) exchange for each existing Right (A) one right with respect to each share
of DLT & Storage Systems group stock (a "DLT & Storage Systems group right")
which will entitle the holders thereof to purchase shares of Series B Junior
Preferred Stock under the conditions specified in the Restated Rights
Agreement, and (B) one right with respect to each share of Hard Disk Drive
group stock (a "Hard Disk Drive group right"), which will entitle the holders
thereof to purchase shares of Series C Junior Preferred Stock under the
conditions specified in the Restated Rights Agreement. The DLT & Storage
Systems group rights and the Hard Disk Drive group rights are herein
collectively referred to as the "rights."

The rights will expire on August 4, 2008, unless earlier redeemed by Quantum or
extended. The rights would be exercisable only if a person or group acquires
(i) 20% or more of the then outstanding shares of DLT & Storage Systems group
stock or (ii) 20% of the then outstanding shares of Hard Disk Drive group
stock, or commences a tender offer that would result in such person or group
beneficially owning such number of shares. In such event, each Right would
entitle the holder to purchase from Quantum (i) in the case of a DLT & Storage
Systems group right, 1/1000 of a share of Series B Junior Preferred Stock (a
"Series B Unit") at a purchase price to be determined by the Board, subject to
adjustment or, under certain circumstances, shares of DLT & Storage Systems
group stock with a market value twice the exercise price of the DLT & Storage
Systems group right and (ii) in the case of a Hard Disk Drive group right,
1/1000 of a share of Series C Junior Preferred Stock (a "Series C Unit") at a
purchase to be determined by the Board, subject to adjustment or, under certain
circumstances, shares of Hard Disk Drive group stock with a market value twice
the exercise price of the Hard Disk Drive group right.

Note 10 Savings and Investment Plan

Substantially all of the regular domestic employees are eligible to make
contributions to Quantum's 401(k) savings and investment plan. Quantum matches
a percentage of the employees' contributions and may also make additional
discretionary contributions to the plan. Quantum contributions were $5 million,
$6 million and $7 million, in fiscal years 1997, 1998 and 1999, respectively.

Pretax income from foreign operations was $241 million, $139 million, and $120
million for the fiscal years ended March 31, 1997, 1998, and 1999,
respectively. U.S. taxes have not been provided for unremitted foreign earnings
of $354 million. The residual U.S. tax liability, if such amounts were
remitted, would be approximately $87 million.

   Quantum's federal income tax returns have been examined by the Internal
Revenue Service (IRS) for all years through 1993. All issues have been resolved
with no material effect, and the IRS has closed those years. Quantum's federal
tax returns for the years 1994-1996 are presently under examination by the IRS.
Management believes sufficient accruals have been provided in prior years for
any adjustments that may result for the years under examination.

Note 12 Litigation

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

On February 25, 1997, in the Santa Clara County action, the Court sustained
defendants' demurrer to most of the causes of action in the complaint, with
leave to amend. At a June 12, 1997 demurrer hearing in state

                                      F-46

court, the judge dismissed the action as to four of the individual defendants
with prejudice and as to three of the individual defendants without prejudice.
The demurrer as to Quantum was overruled. The Court heard oral argument on
plaintiffs' motion for class certification on November 4, 1997. On March 4,
1998, the Court entered an order denying plaintiffs' motion without prejudice.
Limited discovery is proceeding.

With respect to the federal action, defendants filed their motion to dismiss on
April 16, 1997. On August 14, 1997, the Court granted defendants' motion to
dismiss without prejudice. On September 11, 1997, plaintiff filed an amended
complaint. Defendants filed a motion to dismiss the amended complaint on
October 24, 1997. The hearing on defendants' motion took place on February 3,
1998. On April 16, 1998, the Court granted defendants' motion to dismiss with
prejudice. On May 19, 1998, plaintiff filed a notice of appeal of the District
Court's dismissal in the United States Court of Appeals for the Ninth Circuit.
On September 25, 1998, plaintiff filed his opening appellate brief. Defendants
filed their answering brief on November 30, 1998. Plaintiff's reply brief was
filed on January 14, 1999.

Certain of Quantum's current and former officers and directors were also named
as defendants in a derivative lawsuit, which was filed on November 8, 1996, in
the Superior Court of Santa Clara County. The derivative complaint was based on
factual allegations substantially similar to those alleged in the class-action
lawsuits. Defendants' demurrer to the derivative complaint was sustained
without prejudice on April 14, 1997. Plaintiffs did not file an amended
complaint. On August 7, 1997, the Court issued an order of dismissal and
entered final judgment dismissing the complaint.

On August 7, 1998, Quantum was named as one of several defendants in a patent
infringement lawsuit filed in the U.S. District Court for the Northern District
of Illinois, Eastern Division. On Quantum's motion, the suit has been moved to
the Northern District of California. The plaintiff, Papst Licensing GmbH, owns
at least 24 U.S. patents which it asserts that Quantum has infringed. Quantum
has studied many of these
patents before and, of the patents it has studied, believes that defenses of
patent invalidity and non-infringement can be asserted. However, Quantum has
not yet had time to make a complete study of all the patents asserted by Papst
and there can be no assurance that Quantum has not infringed on these or other
patents owned by Papst. The final results of this litigation, as with any
litigation, are uncertain. If required, there can be no assurance that licenses
to any technology owned by Papst or any other third party alleging infringement
could be obtained on commercially reasonable terms if at all. Adverse
resolution of the Papst litigation or any other intellectual property
litigation could subject Quantum to substantial liabilities and require it to
refrain from manufacturing certain products which could have a material adverse
effect on Quantum's business, financial condition or results of operations. In
addition, the costs of engaging in the Papst litigation or other intellectual
property litigation could be substantial, regardless of the outcome.

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

Note 13 Commitments

Quantum leases certain facilities for the Hard Disk Drive group's use under
non-cancelable operating lease agreements for periods of up to 15 years. Some
of the leases have renewal options ranging from one to ten years and contain
provisions for maintenance, taxes, or insurance.

The Hard Disk Drive group's rent expense was $22 million, $21 million, and $22
million for the fiscal years ended March 31, 1997, 1998, and 1999,
respectively.

Note 14 Business Units and Geographic Information

The Hard Disk Drive group currently has two primary product lines, desktop hard
disk drives and high-end hard disk drives. The Hard Disk Drive group has two
separate business units that support these two product lines. In addition,
through May 15, 1997, recording heads were manufactured by the Hard Disk Drive
group and were used only in the Hard Disk Drive group hard disk drives.

   The desktop business unit designs, develops and markets desktop hard disk
drives designed to meet the storage requirements of entry-level to high-end
desktop personal computers in home and business environments. The high-end
business unit designs, develops and markets high-end hard disk drives designed
to meet the storage requirements of network servers, workstations and storage
subsystems. In the future, the two the Hard Disk Drive group business units may
become a single business unit as their markets begin to merge and be reported
on a combined basis.

The Hard Disk Drive group's recording heads business through May 15, 1997 was
reported in the Hard Disk Drive group's combined operations. Effective May 16,
1997, MKE acquired a 51% interest in the Hard Disk Drive group's recording
heads business which became part of a joint venture with MKE. The Hard Disk
Drive group accounted for its 49% interest in the joint venture using the
equity method. On October 28, 1998, the joint venture was dissolved and a
charge was recorded to write-off assets and recognize obligations related to
the dissolution. For more information on the loss from investee see note 5 of
the notes to combined financial statements.

Note 15 Earnings Per Share

On July 23, 1999, Quantum's stockholders approved the tracking stock proposal.
Accordingly, the earnings (loss) per share for the periods presented below have
been calculated in accordance with the Restated Certificate of Incorporation.

  The computation of diluted net loss per share in fiscal year 1999 excluded
the effect of the 7% convertible subordinated notes issued in July 1997, which
are convertible into 3,103,076 shares of HDDG common stock, or 10.793 shares
per $1000 note, because the effect would have been antidilutive.

  Options to purchase 11,688,249 shares of HDDG common stock were outstanding
at March 31, 1999. However, the corresponding weighted average outstanding
options were not included in the computation of diluted net loss per shares for
the fiscal year ended March 31, 1999, because the effect would have been
antidilutive.

        (B) if the Parent Average Stock Price is greater than $20.00, then
      each outstanding share of Company Common Stock shall be converted
      into the number of shares of Parent Common Stock determined by
      dividing $10.00 by the Parent Average Stock Price.

    (b) The fraction of a share of Parent Common Stock into which each
  outstanding share of Company Common Stock is to be converted pursuant to
  Section 1.5(a)(iv) (as such fraction may be adjusted from time to time in
  accordance with this Section 1.5(b)) is referred to as the "Exchange
  Ratio." If, between the date of this Agreement and the Effective Time, the
  outstanding shares of Company Common Stock or Parent Common Stock are
  changed into a different number or class of shares by reason of any stock
  split,

                                      A-2
<PAGE>

  division or subdivision of shares, stock dividend, reverse stock split,
  consolidation of shares, reclassification, recapitalization or other
  similar transaction, then the Exchange Ratio shall be appropriately
  adjusted. For example, if one share of Parent Common Stock, as constituted
  on the date hereof, is reconstituted into one share of Class A Common Stock
  and one-half of a share of Class B Common Stock and the Exchange Ratio is
  0.5 such that 2 shares of Company Common Stock would convert into 1 share
  of Parent Common Stock as constituted on the date hereof, then with respect
  to the conversion into the reconstituted shares, 2 shares of Company Common
  Stock would be converted into 1 share of Class A Common Stock and 1/2 a
  share of Class B Common Stock.

    (c) If any shares of Company Common Stock outstanding immediately prior
  to the Effective Time are unvested or are subject to a repurchase option,
  risk of forfeiture or other condition under any applicable restricted stock
  purchase agreement or other agreement with the Company or under which the
  Company has any rights, then (unless such condition terminates by virtue of
  the Merger pursuant to the express term of such agreement) the shares of
  Parent Common Stock issued in exchange for such shares of Company Common
  Stock will also be unvested and subject to the same repurchase option, risk
  of forfeiture or other condition, and the certificates representing such
  shares of Parent Common Stock may accordingly be marked with appropriate
  legends. The Company shall take all action that may be necessary to ensure
  that, from and after the Effective Time, Parent is entitled to exercise any
  such repurchase option or other right set forth in any such restricted
  stock purchase agreement or other agreement.

    (d) No fractional shares of Parent Common Stock shall be issued in
  connection with the Merger, and no certificates or scrip for any such
  fractional shares shall be issued. Any holder of Company Common Stock who
  would otherwise be entitled to receive a fraction of a share of Parent
  Common Stock (after aggregating all fractional shares of Parent Common
  Stock issuable to such holder) shall, in lieu of such fraction of a share
  and upon surrender of such holder's Company Stock Certificate(s) (as
  defined in Section 1.6), be paid in cash the dollar amount (rounded to the
  nearest whole cent), without interest, determined by multiplying such
  fraction by the closing price of a share of Parent Common Stock on Nasdaq
  on the Effective Date (or, if such date is not a trading day, then the
  trading day immediately preceding the Effective Date).

  1.6 Stock Options. At the Effective Time, all Company Options (as defined in
Section 2.3(b)) shall be assumed by Parent in accordance with Section 5.4.

  1.7 Closing of the Company's Transfer Books. At the Effective Time: (a) all
shares of Company Common Stock outstanding immediately prior to the Effective
Time shall automatically be canceled and retired and shall cease to exist, and
all holders of certificates representing shares of Company Common Stock that
were outstanding immediately prior to the Effective Time shall cease to have
any rights as stockholders of the Company; and (b) the stock transfer books of
the Company shall be closed with respect to all shares of Company Common Stock
outstanding immediately prior to the Effective Time. No further transfer of any
such shares of Company Common Stock shall be made on such stock transfer books
after the Effective Time. If, after the Effective Time, a valid certificate
previously representing any shares of Company Common Stock (a "Company Stock
Certificate") is presented to the Exchange Agent (as defined in Section 1.8) or
to the Surviving Corporation or Parent, such Company Stock Certificate shall be
canceled and shall be exchanged as provided in Section 1.8.

  1.8 Exchange of Certificates.

    (a) Harris Trust and Savings Bank or such other reputable bank or trust
  company selected by Parent prior to the Closing Date shall act as exchange
  agent in the Merger (the "Exchange Agent"). Promptly after the Effective
  Time, Parent shall deposit with the Exchange Agent (i) certificates
  representing the shares of Parent Common Stock issuable pursuant to this
  Section 1, and (ii) cash sufficient to make payments in lieu of fractional
  shares in accordance with Section 1.5(d). The shares of Parent Common Stock
  and cash amounts so deposited with the Exchange Agent, together with any
  dividends or

                                      A-3
<PAGE>

  distributions received by the Exchange Agent with respect to such shares,
  are referred to collectively as the "Exchange Fund."

    (b) As soon as practicable after the Effective Time, the Exchange Agent
  will mail to the record holders of Company Stock Certificates (i) a letter
  of transmittal in customary form and containing such provisions as Parent
  may reasonably specify (including a provision confirming that delivery of
  Company Stock Certificates shall be effected, and risk of loss and title to
  Company Stock Certificates shall pass, only upon delivery of such Company
  Stock Certificates to the Exchange Agent), and (ii) instructions for use in
  effecting the surrender of Company Stock Certificates in exchange for
  certificates representing Parent Common Stock. Upon surrender of a Company
  Stock Certificate to the Exchange Agent for exchange, together with a duly
  executed letter of transmittal and such other documents as may be
  reasonably required by the Exchange Agent or Parent, (1) the holder of such
  Company Stock Certificate shall be entitled to receive in exchange therefor
  a certificate representing the number of whole shares of Parent Common
  Stock that such holder has the right to receive pursuant to the provisions
  of Section 1.5 (and cash in lieu of any fractional share of Parent Common
  Stock), and (2) the Company Stock Certificate so surrendered shall be
  canceled. Until surrendered as contemplated by this Section 1.8(b), each
  Company Stock Certificate shall be deemed, from and after the Effective
  Time, to represent only the right to receive shares of Parent Common Stock
  (and cash in lieu of any fractional share of Parent Common Stock) as
  contemplated by Section 1.5. If any Company Stock Certificate shall have
  been lost, stolen or destroyed, Parent may, in its discretion and as a
  condition precedent to the issuance of any certificate representing Parent
  Common Stock, require the owner of such lost, stolen or destroyed Company
  Stock Certificate to provide an appropriate affidavit and to deliver a bond
  (in such sum as Parent may reasonably direct) as indemnity against any
  claim that may be made against the Exchange Agent, Parent or the Surviving
  Corporation with respect to such Company Stock Certificate.

    (c) No dividends or other distributions declared or made with respect to
  Parent Common Stock with a record date after the Effective Time shall be
  paid to the holder of any unsurrendered Company Stock Certificate with
  respect to the shares of Parent Common Stock which such holder has the
  right to receive upon surrender thereof until such holder surrenders such
  Company Stock Certificate in accordance with this Section 1.8 (at which
  time such holder shall be entitled, subject to the effect of applicable
  escheat or similar laws, to receive all such dividends and distributions,
  without interest).

    (d) Any portion of the Exchange Fund that remains undistributed to
  holders of Company Stock Certificates as of the date 180 days after the
  date on which the Merger becomes effective shall be delivered to Parent
  upon demand, and any holders of Company Stock Certificates who have not
  theretofore surrendered their Company Stock Certificates in accordance with
  this Section 1.8 shall thereafter look only to Parent for satisfaction of
  their claims for Parent Common Stock, cash in lieu of fractional shares of
  Parent Common Stock and any dividends or distributions with respect to
  Parent Common Stock.

    (e) Neither Parent nor the Surviving Corporation shall be liable to any
  holder or former holder of Company Common Stock or to any other Person with
  respect to any shares of Parent Common Stock (or dividends or distributions
  with respect thereto), or for any cash amounts, delivered to any public
  official pursuant to any applicable abandoned property law, escheat law or
  similar Legal Requirement.

  1.9 Dissenting Shares. Notwithstanding anything to the contrary contained in
this Agreement, any shares of Company Common Stock outstanding immediately
prior to the Effective Time that are or may become "dissenting shares" within
the meaning of Section 1300(b) of the California Corporations Code (the "CCC"),
if such section is applicable to this Merger, ("Dissenting Shares") shall not
be converted into or represent the right to receive Parent Common Stock in
accordance with Section 1.5(a)(iii) (or cash in lieu of fractional shares in
accordance with Section 1.5(d)), and each holder of Dissenting Shares shall be
entitled only to such rights as may be granted to such holder under Chapter 13
of the CCC. From and after the Effective Time, a holder of Dissenting Shares
shall not be entitled to exercise any of the voting rights or other rights of a

                                      A-4
<PAGE>

shareholder of the Surviving Corporation. If any holder of Dissenting Shares
shall fail to assert or perfect, or shall waive, rescind, withdraw or otherwise
lose, such holder's right to dissent and obtain payment under Chapter 13 of the
CCC, then such shares shall automatically be converted into and shall represent
only the right to receive (upon the surrender of Company Stock Certificate(s)
previously representing such shares) Parent Common Stock in accordance with
Section 1.5(a)(iii) (and cash in lieu of any fractional share in accordance
with Section 1.5(d)) and any dividends or other distributions to which such
holder is entitled in accordance with Section 1.8.

  1.10 Tax Consequences. For federal income tax purposes, the Merger is
intended to constitute a reorganization within the meaning of Section 368 of
the Code. The parties to this Agreement hereby adopt this Agreement as a "plan
of reorganization" within the meaning of Sections 1.368-2(g) and 1.368-3(a) of
the United States Treasury Regulations.

  1.11 Accounting Consequences. For financial reporting purposes, the Merger is
intended to be accounted for as a purchase.

  1.12 Further Action. If, at any time after the Effective Time, any further
action is determined by Parent to be necessary or desirable to carry out the
purposes of this Agreement or to vest the Surviving Corporation with full
right, title and possession of and to all rights and property of Merger Sub and
the Company, the officers and directors of the Surviving Corporation and Parent
shall be fully authorized (in the name of Merger Sub, in the name of the
Company and otherwise) to take such action.

    (a) The Company has no Subsidiaries and the Company does not own any
  capital stock of, or any equity interest of any nature in, any other
  Entity, other than the Entities identified in Part 2.1(a)(ii) of the
  Company Disclosure Schedule. The Company has not agreed and is not
  obligated to make, nor bound by any Contract under which it may become
  obligated to make, any future investment in or capital contribution to any

  the manner in which its assets are currently owned and used; and (iii) to
  perform its obligations under all Contracts by which it is bound.

    (c) The Company is qualified to do business as a foreign corporation, and
  is in good standing, under the laws of all jurisdictions where the nature
  of its business requires such qualification and where the failure to be so
  qualified would reasonably be expected to have a Material Adverse Effect on
  the Company.

  2.2 Certificate of Incorporation and Bylaws. The Company has delivered to
Parent accurate and complete copies of its certificate of incorporation, bylaws
and other charter and organizational documents, including all amendments

  any shares of Company Common Stock that are subject to a Contract pursuant
  to which the Company has the right to repurchase, redeem or otherwise
  reacquire any shares of Company Common Stock will, without any further act
  of Parent, the Company or any other Person, become subject to the
  restrictions, conditions and other provisions contained in such Contract,
  and (B) Parent will automatically succeed to and become entitled to

  1992 Employee Stock Purchase Plan (the "ESPP"). (Stock options granted by
  the Company pursuant to the Company's stock option plans that are currently
  in effect or that have been in effect and otherwise are referred to in this
  Agreement as "Company Options.") There are no Company Options other than
  Company Options outstanding under the Option Plans. Part 2.3(b)(i) of the
  Company Disclosure Schedule sets forth the following information with
  respect to each Company Option outstanding as of the date of this
  Agreement: (i) the particular plan (if any) pursuant to which such Company

  call, warrant or right (whether or not currently exercisable) to acquire

  outstanding security, instrument or obligation that is or may become
  convertible into or exchangeable for any shares of the capital stock or
  other securities of the Company; (iii) stockholder rights plan (or similar
  plan commonly referred to as a "poison pill") or Contract under which the
  Company is or may become obligated to sell or otherwise issue any shares of
  its capital stock or any other securities; or (iv) condition or
  circumstance that may give rise to or provide a basis for the assertion of
  a claim by any Person to the effect that such

                                      A-6

  currently exercisable) to use, license or otherwise exploit any Company
  Proprietary Asset.

    (b)

      (i) The Company has taken reasonable measures and precautions to

    Agreement previously delivered to Parent. No current or former
    employee, officer, director, stockholder, consultant or independent
    contractor has any right, claim or interest in or with respect to any
    Company Proprietary Asset.

    delivered to the Company an agreement (containing no exceptions to or
    exclusions from the scope of its coverage) that is substantially
    identical to the form of Confidential Non-Disclosure Agreement
    previously delivered to Parent.

    (c) To the best of the knowledge of the Company: (i) all patents,
  trademarks, service marks and copyrights held by the Company are valid,
  enforceable and subsisting; (ii) none of the Company Proprietary Assets and
  no Proprietary Asset that is currently being developed by the Company
  (either by itself or with any other Person) infringes, misappropriates or

  writing or otherwise) of any actual, alleged, possible or potential
  infringement, misappropriation or unlawful or unauthorized use of, any
  Proprietary Asset owned or used by any other Person; (iv) no other Person

  2.9(d)(ii) of the Company Disclosure Schedule, the Company has not (i)
  licensed any of the material Company Proprietary Assets to any Person on an

  condition exists, that (with or without notice or lapse of time) will, or
  could reasonably be expected to, result in the disclosure or delivery to
  any Person of any Company Source Code. Part 2.10(a)(xii) of the Company
  Disclosure Schedule identifies each Contract pursuant to which the Company
  has deposited or is required to deposit with an escrowholder or any other
  Person any Company Source Code, and further describes whether the execution
  of this Agreement or the consummation of any of the transactions
  contemplated hereby could reasonably be expected to result in the release
  or disclosure of any Company Source Code. Part 2.9(e)(ii) of the Company
  Disclosure Schedule lists the Company Source Code or portions thereof which
  the Company plans to annotate with comments in a manner as is customary for
  software developers which would facilitate the maintenance and enhancement
  of such Company Source Code.

  conforms in all material respects to design specifications and documented
  performance criteria; and (iii) there has not been any claim by any
  customer or other Person alleging that any Company Proprietary Asset
  (including each version thereof that has ever been licensed or otherwise
  made available by the Company to any Person) does not conform in all
  material respects with any specification, documentation, performance
  standard, or documented performance criteria made or provided by or on
  behalf of the Company, and, to the best of the knowledge of the Company,
  there is no basis for any such claim. To the best of the knowledge of the
  Company, the Company has established adequate reserves on the Company
  Balance Sheet to cover all costs associated with any obligations that the
  Company may have with respect to the correction or repair of programming
  errors or other defects in the Company Proprietary Assets.

  Schedule, each computer program and other item of software that has been
  designed, developed, sold, licensed or otherwise made available to any

  2.9(g)(iii) of the Company Disclosure Schedule, the Company has conducted
  sufficient Year 2000 compliance testing for each computer, computer program
  and item of software referred to in the preceding two sentences to be able

  is Year 2000 Compliant, and has obtained warranties or other written
  assurances from each of its suppliers to the effect that the products and
  services provided by such suppliers to the Company is Year 2000 Compliant.
  As used in this Agreement, "Year 2000 Compliant" means, with respect to a
  computer, computer program or other item of software, that

  such computer, computer program or other items of software will properly
  perform date sensitive functions before, during and after the Year 2000.
  Part 2.9(g)(iv) of the Company Disclosure Schedule sets forth a brief
  description of the Year 2000 Compliant and non-Year 2000 Compliant systems,
  and a brief description of the actions taken to date, and proposed to be
  taken, with respect to all Company utilized systems.

    (h) Except with respect to demonstration or trial copies, no product,
  system, program or software module designed, developed, sold, licensed or
  otherwise made available by the Company to any Person contains any "back
  door," "time bomb," "Trojan horse," "worm," "drop dead device," "virus" or
  other software routines or hardware components designed to permit
  unauthorized access or to disable or erase software, hardware or data
  without the consent of the user.

  defect or deficiency at the time it was sold or otherwise made available,
  other than any immaterial bug or similar defect that would not adversely
  affect in any material respect such SNAP product, SNAP system, SNAP
  program, SNAP Company Proprietary Asset or other SNAP asset (or the
  operation or performance thereof). Part 2.9(i) of the Company Disclosure
  Schedule contains an accurate and complete copy of the most recent "bug
  list" with respect to each SNAP product and SNAP product under development
  or pre-release testing.

  Schedule, each product, system, program, Proprietary Asset or other asset

  sold, installed, repaired, licensed or otherwise made available by the
  Company to any Person was free of any bug, virus, design defect or other
  defect or deficiency at the time it was sold or otherwise made available,

  Section 414(b), (c), (m) or (o) of the Code. The Company has never been a
  member of an "affiliated service group" within the meaning of Section
  414(m) of the Code. The Company has never made a complete or partial
  withdrawal from a multiemployer plan, as such term is defined in Section

  ERISA).

    (f) The Company has no plan or commitment to create any additional

    (j) Each of the Plans intended to be qualified under Section 401(a) of
  the Code has received a favorable determination letter as to its
  qualification from the Internal Revenue Service, and nothing has occurred
  that would adversely affect the ability of the Company to rely on each such
  determination letter.

    (k) Except as set forth in Part 2.17(k) of the Company Disclosure
  Schedule, neither the execution, delivery or performance of this Agreement,
  nor the consummation of the Merger or any of the other transactions
  contemplated by this Agreement, will result in any bonus, golden parachute,
  severance or other payment or obligation to any current or former employee
  or director of the Company (whether or not under any Plan), or materially
  increase the benefits payable or provided under any Plan, or result in any
  acceleration of the time of payment, provision or vesting of any such
  benefits. Without limiting the generality of the foregoing (and except as
  set forth in Part 2.17(k) of the Company Disclosure Schedule), the
  consummation of the Merger will not result in the acceleration of vesting
  of any unvested Company Options.

    (l) Part 2.17(l) of the Company Disclosure Schedule identifies each
  employee of the Company as of the date of this Agreement, and correctly
  reflects, in all material respects, the current salary and any other

  employee's employer, date of hire and position and the principal office of
  such employee. The Company is not a party to any collective bargaining
  contract or other Contract with a labor union involving any of its
  employees. All of the employees of the Company are "at will" employees.

    (m) Part 2.17(m) of the Company Disclosure Schedule identifies each
  employee of the Company who is not fully available to perform work because
  of disability or other leave and sets forth the basis of such disability or
  leave and the anticipated date of such employee's return to full service.

  knowledge of any facts indicating that (i) the consummation of the Merger
  or any of the other transactions contemplated by this Agreement will have a
  material adverse effect on the labor relations of the Company, or (ii) as
  of the date of this Agreement, any of the employees of the Company intend
  to terminate his or her employment with the Company.

  2.18 Environmental Matters. The Company is in compliance in all material
respects with all applicable Environmental Laws, which compliance includes the

required under applicable Environmental Laws, and compliance with the terms and
conditions thereof. The Company has not received any notice or other
communication (in writing or otherwise), whether from a Governmental Body,
citizens group, employee or otherwise, that alleges that the Company is not in
compliance with any Environmental Law, and, to the best of the knowledge of the
Company, there are no circumstances that may prevent or interfere with the
compliance by the Company with any Environmental Law in the future. To the best
of the knowledge of the Company, no current or prior owner of any property
leased or controlled by the Company has received any notice or other
communication (in writing or otherwise), whether from a Government Body,
citizens group, employee or otherwise, that alleges that such current or prior
owner or the Company is not in compliance with any Environmental Law. To the

by or used by the Company, and all surface water, groundwater and soil
associated with or adjacent to such property is free of any material
environmental contamination of any nature, (b) none of the property leased to,
controlled by or used by the Company contains any underground storage tanks,
asbestos, equipment using PCBs, underground injection wells, and (c) none of

of Environmental Concern to a site that, pursuant to any applicable
Environmental Law (i) has been placed on the "National Priorities List" of
hazardous waste sites or any similar state list, (ii) is otherwise designated
or identified as a potential site for remediation, cleanup, closure or other

business, assets and operations of the Company. Each such insurance policy is

any notice or other communication regarding any actual or possible (a)
cancellation or invalidation of any such insurance policy, (b) refusal of any
coverage or rejection of any material claim under any insurance policy, or (c)
material adjustment in the amount of the premiums payable with respect to any
insurance policy. Except as set forth in Part 2.19 of the Company Disclosure
Schedule, there is no pending workers' compensation or other claim under or
based upon any insurance policy of the Company; and, to the best of the
knowledge of the Company, no event has occurred, and no condition or
circumstance exists, that might (with or without notice or lapse of time)
directly or indirectly give rise to or serve as a basis for any such claim.

  2.20 Transactions with Affiliates. Except as set forth in the Company SEC
Reports, since the date of the Company's last proxy statement filed with the
SEC, no event has occurred that would be required to be reported by the Company

to be) an "affiliate" (as that term is used in Rule 145 under the Securities
Act) of the Company as of the date of this Agreement.

  2.21 Legal Proceedings; Orders.

    (a) As of the date hereof, there is no pending Legal Proceeding, and to
  the best of the knowledge of the Company, no Person has threatened to
  commence any Legal Proceeding: (i) that involves the Company or any of the
  assets owned or used by the Company; or (ii) that challenges, or that may
  have the effect of preventing, delaying, making illegal or otherwise
  interfering with, the Merger or any of the other transactions contemplated
  by this Agreement. To the best of the knowledge of the Company, no event
  has occurred, and no claim, dispute or other condition or circumstance
  exists, that could reasonably be expected to, give rise to or serve as a
  basis for the commencement of any such Legal Proceeding. To the best of the
  knowledge of the Company, no event has occurred, and no claim, dispute or
  other circumstance or condition exists, that will, or that could reasonably
  be expected to, cause or provide a basis for a director, officer or other
  representative of the Company to seek indemnification from, or commence a
  Legal Proceeding against or involving, the Company.

    (b) There is no material order, writ, injunction, judgment or decree to
  which the Company, or any of the assets owned or used by the Company, is
  subject. To the best of the knowledge of the Company, no officer or key

  Parent in writing of: (i) the discovery by the Company of any event,
  condition, fact or circumstance that occurred or existed on or prior to the
  date of this Agreement and that caused or constitutes a material inaccuracy
  in any representation or warranty made by the Company in this Agreement;
  (ii) any event, condition, fact or circumstance that occurs, arises or
  exists after the date of this Agreement and that would cause or constitute
  a material inaccuracy in any representation or warranty made by the Company
  in this Agreement if (A) such representation or warranty had been made as
  of the time of the occurrence, existence or discovery of such event,
  condition, fact or circumstance, or (B) such event, condition, fact or
  circumstance had occurred, arisen or existed on or prior to the date of
  this Agreement; (iii) any event, condition, fact or circumstance hereafter

  otherwise affect any of the representations, warranties, covenants or
  obligations of the Company contained in this Agreement.

    (d) If any event, condition, fact or circumstance that is required to be

  as of the date of the occurrence, existence or discovery of such event,
  condition, fact or circumstance, then the Company shall promptly deliver to
  Parent an update to the Company Disclosure Schedule specifying such change.
  No such update shall be deemed to supplement or amend the Company
  Disclosure Schedule for the purpose of (i) determining the accuracy of any
  of the representations and warranties made by the Company in this
  Agreement, or (ii) determining whether any of the conditions set forth in
  Section 6 has been satisfied.

  4.3 No Solicitation.

    (a) From the date of this Agreement until the earlier of the Effective

      (v) enter into any letter of intent or similar document or any

provided, however, that (A) nothing herein shall prohibit the Company's board
of directors from disclosing to the Company's stockholders a position with
respect to a tender offer pursuant to Rules 14d-9 and 14e-2 promulgated under
the Exchange Act and (B) prior to the adoption and approval of this Agreement
by the Required Company Stockholder Vote, the Company shall not be prohibited
by this Section 4.3(a) from (x) furnishing nonpublic information regarding the
Company to, or (y) entering into discussions with, any Person in response to a
Superior Offer that is submitted by such Person (and not withdrawn) if:

        (1) neither the Company nor any Representative of the Company
      shall have violated any of the restrictions set forth in this
      Section 4.3;

        (2) the board of directors of the Company concludes in good faith,
      based upon the advice of its outside legal counsel, that such action
      is required in order for the board of directors of the Company to
      comply with its fiduciary obligations to the Company's stockholders
      under applicable law;

        (3) prior to furnishing any such nonpublic information to, or
      entering into discussions with, such Person, the Company gives
      Parent written notice of the identity of such Person and of the
      Company's intention to furnish nonpublic information to, or enter
      into discussions with, such Person, and the Company receives from
      such Person an executed confidentiality agreement containing
      customary limitations on the use and disclosure of all nonpublic
      written and oral information furnished to such Person by or on
      behalf of the Company; and


                                     A-27
<PAGE>

        (4) prior to furnishing any such nonpublic information to such
      Person, the Company furnishes such nonpublic information to Parent
      (to the extent such nonpublic information has not been previously
      furnished by the Company to Parent).

Without limiting the generality of the foregoing, the Company acknowledges and
agrees that any violation of any of the restrictions set forth in the preceding
sentence by any Representative of the Company, whether or not such
Representative is purporting to act on behalf of the Company, shall be deemed
to constitute a breach of this Section 4.3 by the Company. In addition to the
foregoing, the Company shall (i) provide Parent with at least forty-eight (48)
hours prior notice of any meeting of the Company's Board of Directors at which
the Company's Board of Directors is reasonably expected to consider a Superior
Offer and (ii) not recommend a Superior Offer to its shareholders for a period
of not less than the greater of three (3) business days or seventy-two (72)
hours after Parent's receipt of a copy of such Superior Offer (pursuant to
Section 4.3(b) below).

    (b) The Company shall promptly advise Parent orally and in writing of any
  Acquisition Proposal (including the identity of the Person making or
  submitting such Acquisition Proposal and the terms thereof) that is made or
  submitted by any Person during the Pre-Closing Period. The Company shall
  keep Parent fully informed with respect to the status of any such
  Acquisition Proposal and any modification or proposed modification thereto.

    (c) The Company shall immediately cease and cause to be terminated any
  existing discussions with any Person that relate to any Acquisition
  Proposal.

  4.4 Proprietary Assets.

    (a) During the Pre-Closing Period, the Company shall use its best efforts
  to evaluate whether products it manufactured prior to December 31, 1997 are
  Year 2000 Compliant, document such compliance or lack thereof, and assess
  the financial impact on the Company for liability to third parties for any
  products the Company manufactured which are not Year 2000 Compliant.

    (b) The Company shall complete the annotations listed in Part 2.9(e)(ii)
  of the Company Disclosure Schedule by June 10, 1999.

  4.5 Termination of Plans. Upon the request of Parent, to the extent permitted
under applicable law and applicable contracts and the terms of such Plan
(including but not limited to the Company's 401(k) Plan), the Company will
terminate any Plan immediately prior to the Closing.

  4.6 Plan Amendment. During the Pre-Closing Period, the Company shall use its
best efforts to amend the Severance Plan as provided in the Plan Amendment.

  4.7 Approval of Delaware Reincorporation. The Company shall take all action
necessary under all applicable Legal Requirements to remedy the California
Company's failure to obtain the requisite shareholder approval prior to filing
the Agreement and Plan of Merger, dated as of May 29, 1997, between the
California Company and the Delaware Company (the "1997 Reincorporation") under
the CCC and the DGCL, such that the Delaware Company shall be the Principal
Company. The Company shall use its best efforts to remedy such failure as
promptly as practicable after the date of this Agreement. If the Company shall
not have remedied such failure to Parent's reasonable satisfaction by June 7,
1999, and if it shall be necessary, in the reasonable judgment of Parent, that,
in order to remedy such failure, the Company needs to hold a special meeting of
the holders of the Company Common Stock (the "Reincorporation Meeting") to
consider, act upon and vote upon the reincorporation of Principal Company in
the State of Delaware or to ratify the 1997 Reincorporation, the Company shall
take all actions necessary under all applicable Legal Requirements to call,
give notice of, convene and hold the Reincorporation Meeting, in each case as
promptly as practicable after the date of such request from Parent; provided,
that in no event shall the Reincorporation Meeting be held later than thirty
(30) days after the mailing of a definitive proxy statement relating to the
Reincorporation Meeting. The Company shall ensure that the Reincorporation
Meeting is called, noticed, convened, held and conducted, and that all

                                      A-28
<PAGE>

proxies solicited in connection with the Reincorporation Meeting are solicited,
in compliance with all applicable Legal Requirements. The Company's obligation
to call, give notice of, convene and hold the Reincorporation Meeting in
accordance with this Section 4.7 shall not be limited or otherwise affected by
the commencement, disclosure, announcement or submission of any Superior Offer
or other Acquisition Proposal, or by any withdrawal, amendment or modification
of the recommendation of the board of directors of the Company with respect to
the Merger.

  4.8 Parent Notification.

    (a) During the Pre-Closing Period, Parent shall promptly notify the
  Company in writing of: (i) the discovery by Parent of any event, condition,
  fact or circumstance that occurred or existed on or prior to the date of
  this Agreement and that caused or constitutes a material inaccuracy in any
  representation or warranty made by Parent in this Agreement; (ii) any
  event, condition, fact or circumstance that occurs, arises or exists after
  the date of this Agreement and that would cause or constitute a material
  inaccuracy in any representation or warranty made by the Company in this
  Agreement if (A) such representation or warranty had been made as of the
  time of the occurrence, existence or discovery of such event, condition,
  fact or circumstance, or (B) such event, condition, fact or circumstance
  had occurred, arisen or existed on or prior to the date of this Agreement;
  (iii) any event, condition, fact or circumstance hereafter arising which,
  if existing or occurring at the date of this Agreement, would have been
  required to be set forth or described in the Parent Disclosure Schedule;
  (iv) any material breach of any covenant or obligation of Parent; and
  (v) any event, condition, fact or circumstance that would make the timely
  satisfaction of any of the conditions set forth in Section 6 or Section 7
  impossible or unlikely. No notification given to the Company pursuant to
  this Section 4.8(a) shall limit or otherwise affect any of the
  representations, warranties, covenants or obligations of Parent contained
  in this Agreement.

    (b) If any event, condition, fact or circumstance that is required to be
  disclosed pursuant to Section 4.8(a) requires any change in the Parent
  Disclosure Schedule, or if any such event, condition, fact or circumstance
  would require such a change assuming Parent Disclosure Schedule were dated
  as of the date of the occurrence, existence or discovery of such event,
  condition, fact or circumstance, then Parent shall promptly deliver to the
  Company an update to the Parent Disclosure Schedule specifying such change.
  No such update shall be deemed to supplement or amend the Parent Disclosure
  Schedule for the purpose of (i) determining the accuracy of any of the
  representations and warranties made by Parent in this Agreement, or (ii)
  determining whether any of the conditions set forth in Section 7 has been
  satisfied.

  postpone the Company Shareholders' Meeting to the extent necessary to
  ensure that any necessary supplement or amendment to the Joint Proxy
  Statement/Prospectus is provided to the Company's shareholders in advance
  of a vote on the Merger and this Agreement or, if as of the time for which

  Joint Proxy Statement/Prospectus) there are insufficient shares of Company
  Common Stock represented (either in person or by proxy) to constitute a
  quorum necessary to conduct the business of the Company's Shareholders'
  Meeting. The Company shall ensure that the Company Stockholders' Meeting is
  called, noticed, convened, held and conducted, and that all proxies
  solicited in connection with the Company Stockholders' Meeting are
  solicited, in compliance with all applicable Legal Requirements. The
  Company's obligation to call, give notice of, convene and hold the Company
  Stockholders' Meeting in accordance with this Section 5.2(a) shall not be

  include a statement to the effect that the board of directors of the
  Company has unanimously recommended that the Company's stockholders vote in
  favor of and adopt and approve this Agreement and approve the Merger at the
  Company Stockholders' Meeting; and (iii) neither the board of directors of
  the Company nor any committee thereof shall withdraw, amend or modify, or
  propose or resolve to withdraw, amend or modify, in a manner adverse to
  Parent, the unanimous recommendation of the board of directors of the
  Company that the Company's stockholders vote in favor of and adopt and
  approve this

                                      A-30
<PAGE>

  Agreement and approve the Merger. For purposes of this Agreement, said
  recommendation of the board of directors of the Company shall be deemed to
  have been modified in a manner adverse to Parent if said recommendation
  shall no longer be unanimous.

    (c) Nothing in Section 5.2(b) shall prevent the board of directors of the
  Company from withdrawing, amending or modifying its unanimous
  recommendation in favor of the Merger at any time prior to the adoption and
  approval of this Agreement by the Required Company Stockholder Vote if (i)
  a Superior Offer is made to the Company and is not withdrawn, (ii) neither
  the Company nor any of its Representatives shall have violated any of the
  restrictions set forth in Section 4.3, (iii) the board of directors of the
  Company concludes in good faith, based upon the advice of its outside

  or modification of such recommendation is required in order for the board
  of directors of the Company to comply with its fiduciary obligations to the
  Company's stockholders under applicable law, (iv) the Company provides
  Parent with at least 48 hours prior notice of any meeting of the Company's
  board of directors at which such board of directors is expected to consider

  Merger for at least 72 hours after the Company provides Parent with the
  name of the Person making such Superior Offer and a copy of such Superior
  Offer. Nothing contained in this Section 5.2 shall limit the Company's
  obligation to call, give notice of, convene and hold the Company
  Stockholders' Meeting (regardless of whether the unanimous recommendation
  of the board of directors of the Company shall have been withdrawn, amended
  or modified).

  5.3 Regulatory Approvals. Each party shall use all reasonable efforts to
file, as promptly as practicable after the date of this Agreement, all notices,
reports and other documents required to be filed by such party with any
Governmental Body with respect to the Merger and the other transactions
contemplated by this Agreement, and to submit promptly any additional
information requested by any such Governmental Body. Without limiting the
generality of the foregoing, the Company and Parent shall, promptly after the
date of this Agreement, prepare and file the notifications required under the
HSR Act in connection with the Merger. The Company and Parent shall respond as
promptly as practicable to (i) any inquiries or requests received from the

law. In addition, except as may be prohibited by any Governmental Body or by
any Legal Requirement, in connection with any Legal Proceeding under or
relating to the HSR Act or any other federal or state antitrust or fair trade
law or any other similar Legal Proceeding, each of the Company and Parent will
permit authorized Representatives of the other party to be present at each
meeting or conference relating to any such Legal Proceeding and to have access
to and be consulted in connection with any document, opinion or proposal made
or submitted to any Governmental Body in connection with any such Legal
Proceeding.

  5.4 Stock Options.

    (a) At the Effective Time, all rights with respect to Company Common
  Stock under each Company Option then outstanding shall be converted into
  and become rights with respect to Parent Common Stock, and Parent shall
  assume each such Company Option in accordance with the terms (as in effect
  as of the date of this Agreement) of the stock option plan under which it
  was issued and the stock option agreement

                                      A-31

  Company Option assumed by Parent may be exercised solely for shares of
  Parent Common Stock, (ii) the number of shares of Parent Common Stock
  subject to each such Company Option shall be equal to the number of shares
  of Company Common Stock subject to such Company Option immediately prior to
  the Effective Time multiplied by the Exchange Ratio, rounded down to the
  nearest whole share, (iii) the per share exercise price under each such
  Company Option shall be adjusted by dividing the per share exercise price
  under such Company Option by the Exchange Ratio and rounded up to the
  nearest cent and (iv) any restriction on the exercise of any such Company
  Option shall continue in full force and effect and the term,
  exercisability, vesting schedule and other provisions of such Company
  Option shall otherwise remain unchanged; provided, however, that each
  Company Option assumed by Parent in accordance with this Section 5.4(a)
  shall, in accordance with its terms, be subject to further adjustment as
  appropriate to reflect any stock split, division or subdivision of shares,
  stock dividend, reverse stock split, consolidation of shares,
  reclassification, recapitalization or other similar transaction subsequent
  to the Effective Time. Parent shall file with the SEC, promptly after the
  date on which the Merger becomes effective, a registration statement on

  respect to the Company Options assumed by Parent in accordance with this
  Section 5.4(a).

  after the Effective Time, holders of Company Options have no rights with
  respect thereto other than those specifically provided in this Section 5.4.

    (c) As of the Effective Time, the ESPP shall be terminated. The rights of
  participants in the ESPP with respect to any offering period then underway
  under the ESPP shall be determined by treating the last business day prior
  to the Effective Time as the last day of such offering period and by making
  such other pro-rata adjustments as may be necessary to reflect the reduced
  offering period but otherwise treating such offering period as a fully
  effective and completed offering period for all purposes of such Plan.
  Prior to the Effective Time, the Company shall take all actions (including,
  if appropriate, amending the terms of the ESPP) that are necessary to give
  effect to the transactions contemplated by this Section 5.4(d).

  5.5 Indemnification of Officers and Directors.

    (a) All rights to indemnification existing in favor of those Persons who
  are directors and officers of the Company as of the date of this Agreement
  (the "Indemnified Persons") for acts and omissions occurring prior to the
  Effective Time, as provided in the Company's Bylaws (as in effect as of the
  date of this Agreement) and as provided in the indemnification agreements
  between the Company and said Indemnified Persons (as in effect as of the
  date of this Agreement), shall survive the Merger and shall be observed by
  the Surviving Corporation and Parent to the fullest extent available under
  Delaware law for a period of six years from the Effective Time.

    (b) From the Effective Time until the third anniversary of the Effective
  Time, the Surviving Corporation or Parent shall maintain in effect, for the
  benefit of the Indemnified Persons with respect to acts or omissions
  occurring prior to the Effective Time, the existing policy of directors'
  and officers' liability insurance maintained by the Company as of the date
  of this Agreement (the "Existing Policy"); provided, however, that (i) the
  Surviving Corporation or Parent may substitute for the Existing Policy a
  policy or policies of comparable coverage, and (ii) the Surviving
  Corporation shall not be required to pay an annual premium for the Existing
  Policy (or for any substitute policies) in excess of 150% of the amount of
  the last annual premium paid by the Company prior to the date of this
  Agreement for the Existing Policy (the "Premium Amount"). In the event any
  future annual premium for the Existing Policy (or any substitute policies)
  exceeds the Premium Amount, the Surviving Corporation or Parent shall be
  entitled to reduce the amount of coverage of the Existing Policy (or any
  substitute policies) to the maximum amount of coverage that can be obtained
  for a premium equal to the Premium Amount.

        the closing price of a share of Parent Common Stock on the
        principal securities exchange or market on which the Parent Common
        Stock is then listed or quoted (which shall either be the Nasdaq

     in its entirety to read as follows:

    (a) The Company shall take all action necessary under all applicable

        Stockholders' Meeting shall not be held fewer than twelve trading
        days following the Parent stockholders' meeting related to the
        tracking stock proposal (the "Parent Meeting") but will be held as
        promptly as practicable after the twelfth day following the Parent
        Meeting, and in any event within forty-five (45) days after the

        Proxy Statement/Prospectus is provided to the Company's

        Common Stock represented (either in person or by proxy) to

        Company Stockholders' Meeting is called, noticed, convened, held
        and conducted, and that all proxies solicited in connection with
        the Company Stockholders' Meeting are solicited, in compliance with
        all applicable Legal Requirements. The Company's obligation to
        call, give notice of, convene and hold the Company Stockholders'
        Meeting in accordance with this Section 5.2(a) shall not be limited
        or otherwise affected by the commencement, disclosure, announcement
        or submission of any Superior Offer or other Acquisition Proposal,

    Nasdaq National Market or the NYSE).

  11.  The definition of "Legal Requirement" in the Original Agreement is
       hereby amended and restated in its entirety to read as follows:

    Legal Requirement. "Legal Requirement" shall mean any federal, state,
    local, municipal, foreign or other law, statute, constitution,
    principle of common law, resolution, ordinance, code, edict, decree,
    rule, regulation, ruling or requirement issued, enacted, adopted,
    promulgated, implemented or otherwise put into effect by or under the

    trading days ending on and including the second trading day immediately
    preceding the date on which a final vote of the stockholders of the

                                     A-1-3

    reconstituted into one share of Class A Common Stock and one-half of a

    price of a share of Class A Common Stock for such consecutive trading
    days is $15.00 and the average of the closing sales price of a share of
    Class B Common Stock for such five trading days is $10.00, then the
    Parent Average Stock Price would be $20.00 (i.e. $15.00 per Class A
    share plus the product of 0.5 of a Class B share times $10.00 per Class
    B share).

  13. Clause (vi) of the definition of "Triggering Event" in the Original

      follows:

    (vi) the Company shall have failed to hold the Company Stockholders'
    Meeting within forty-five (45) days after the later of (A) the date the
    Form S-4 Registration Statement is declared effective under the
    Securities Act or (B) either the Parent Meeting (if the proxy materials
    for the Parent Meeting shall have been mailed by August 31, 1999) or
    October 31, 1999 (if the proxy materials for the Parent Meeting shall
    not have been mailed by August 31, 1999);

      Agreement, as amended by this First Amendment.

  15. Except as amended by this First Amendment, the Original Agreement
      remains in full force and effect.

  16. This First Amendment is made under, and shall be construed and enforced
      in accordance with, the laws of the State of Delaware applicable to
      agreements made and to be performed solely therein, without giving
      effect to principles of conflicts of law.

Board of Directors
Meridian Data, Inc.

Scotts Valley, California 95066

Dear Sirs:

  You have requested our opinion as to the fairness from a financial point of
view to the holders of common stock, par value $0.001 per share ("Company
Common Stock"), of Meridian Data, Inc. (the "Company") of the consideration to
be received by such holders pursuant to the terms of the Agreement and Plan of
Merger and Reorganization (the "Agreement"), by and among Quantum Corporation
("Quantum"), Defiant Acquisition Sub, Inc., a wholly owned subsidiary of
Quantum ("Merger Sub"), and the Company, pursuant to which Merger Sub will be
merged (the "Merger") with and into the Company, with the Company surviving as
a wholly owned subsidiary of Quantum.

  Pursuant to the Agreement, each share of Company Common Stock will be
converted, subject to certain exceptions, into the right to receive 0.489
shares of common stock, par value $0.01 per share ("Quantum Common Stock"), of
Quantum; provided, however, that if (i) the average of the closing sales price
of a share of Quantum Common Stock for each of the 10 consecutive trading days
ending on and including the second trading day immediately preceding the date
on which a final vote of the stockholders of the Company on the adoption and
approval of the Agreement and the approval of the Merger is held ("Average
Quantum Stock Price") is less than $14.00, then each outstanding share of
Company Common Stock will be converted into the number of shares of Quantum
Common Stock determined by dividing $7.00 by the Average Quantum Stock Price
and (ii) if the Average Quantum Stock Price is greater than $20.00, then each
outstanding share of Company Common Stock will be converted into the number of
shares of Quantum Common Stock determined by dividing $10.00 by the Average
Quantum Stock Price.

  In arriving at our opinion, we have reviewed the draft dated May 5, 1999 of
the Agreement. We also have reviewed financial and other information that was
publicly available or furnished to us by the Company including information
provided during discussions with its management. Included in the information
provided during discussions with Company management were certain financial
projections of the Company for the period beginning January 1, 1999 and ending
December 31, 2002 prepared by the management of the Company (the "Company
Projections"). At the direction of the Company, for purposes of our analysis,
we have also relied on the financial forecasts for Quantum prepared and
published by the equity research department of Donaldson, Lufkin & Jenrette
Securities Corporation ("DLJ"), for the period beginning April 1, 1999 and
ending March 31, 2001, dated as of April 28, 1999 (the "Quantum Projections").
We were not provided with any internal financial analyses or forecasts of
Quantum prepared by management of Quantum. In addition, we have compared
certain financial and securities data of the Company and Quantum with various
other companies whose securities are traded in public markets, reviewed the
historical stock prices and trading volumes of Company Common Stock and Quantum
Common Stock, reviewed prices and premiums paid in certain other business
combinations and conducted such other financial studies, analyses and
investigations as we deemed appropriate for purposes of this opinion. We were
not requested to, nor did we, solicit the interest of any other party in
acquiring the Company.

  In rendering our opinion, we have relied upon and assumed the accuracy and
completeness of all of the financial and other information that was available
to us from public sources, that was provided to us by the Company and Quantum
or their representatives, or that was otherwise reviewed by us. With respect to
the Company Projections, we have assumed that they have been reasonably
prepared on the basis reflecting the best

                                      B-1
<PAGE>

currently available estimates and judgments of the manangement of the Company
to as to the future operating and financial performance of the Company. With
respect to the Quantum Projections, we have assumed that they do not differ
materially from the best estimates and judgments of the management of Quantum
as to the future operating and financial performance of Quantum. We have not
assumed any responsibility for making an independent evaluation of any assets
or liabilities or for making any independent verification of any of the
information reviewed by us.

  Our opinion is necessarily based on economic, market, financial and other
conditions as they exist on, and on the information made available to us as of,
the date of this letter. It should be understood that, although subsequent
developments may affect this opinion, we do not have any obligation to update,
revise or reaffirm this opinion. We are expressing no opinion herein as to the
prices at which Quantum Common Stock or any other security issued by Quantum,
including the securities described in the Form S-4 filed by Quantum with the
Securities and Exchange Commission on March 26, 1999 (the "Tracking Stocks"),
will actually trade at any time. Our opinion does not address the relative
merits of the Merger and the other business strategies being considered by the
Company's Board of Directors, nor does it address the Board's decision to
proceed with the Merger. Our opinion does not constitute a recommendation to
any stockholder as to how such stockholder should vote on the proposed
transaction.

  DLJ, as part of its investment banking services, is regularly engaged in the
valuation of businesses and securities in connection with mergers,
acquisitions, underwritings, sales and distributions of listed and unlisted
securities, private placements and valuations for corporate and other purposes.

  Based upon the foregoing and such other factors as we deem relevant, we are
of the opinion that the consideration to be received by the holders of Company
Common Stock pursuant to the Agreement is fair to such holders from a financial
point of view.

                                          Very truly yours,

                                          DONALDSON, LUFKIN & JENRETTE

  delegation of any of such interests or obligations shall be void. Subject
  to the preceding sentence, this Agreement shall be binding upon Stockholder

  The undersigned stockholder of Meridian Data, Inc., a Delaware corporation

                      FORM OF COMPANY AFFILIATE AGREEMENT

  This Company Affiliate Agreement (this "Agreement") is dated as of May 10,
1999, by and between Quantum Corporation, a Delaware corporation ("Parent"),
Meridian Data, Inc., a Delaware corporation (the "Delaware Company"), Meridian
Data, Inc., a California corporation (the "California Company") (the California
Company and the Delaware Company are referred to herein as the "Company"), and
the undersigned affiliate ("Affiliate").

                                    RECITALS

  Whereas, Affiliate is a stockholder of Company.

  Whereas, Parent, Defiant Acquisition Sub, Inc., a Delaware corporation and a
wholly-owned subsidiary of Parent ("Merger Sub"), and Company have entered into
an Agreement and Plan of Merger and Reorganization dated as of May 10, 1998
(the "Merger Agreement"), providing for the merger of Merger Sub with and into
Company (the "Merger"). The Merger Agreement contemplates that, upon
consummation of the Merger, (i) the holders of the common stock of Company
("Company Common Stock") will receive shares of common stock of Parent ("Parent
Common Stock") in exchange for their shares of Company Common Stock and (ii)
Company will become a wholly-owned subsidiary of Parent. It is accordingly
contemplated that Affiliate will receive shares of Parent Common Stock in the
Merger.

  Whereas, Affiliate understands that the Parent Common Stock being issued in
the Merger will be issued pursuant to a registration statement on Form S-4 and
that Affiliate may be deemed to be an "affiliate" of Company, as the term
"affiliate" is used for purposes of paragraphs (c) and (d) of Rule 145 ("Rule
145") of the General Rules and Regulations of the Securities and Exchange
Commission (the "SEC") under the Securities Act of 1933, as amended (the
"Securities Act"), and, as such, Affiliate may only transfer, sell or dispose
of such Parent Common Stock in accordance with this Affiliate Agreement and
Rule 145.

                                   AGREEMENT
  Now, Therefore, in order to induce Parent and Company to consummate the
transactions contemplated by the Merger Agreement, and for other valuable
consideration (the receipt and sufficiency of which are hereby acknowledged by
Affiliate), Affiliate hereby covenants and agrees as follows:

  1. Representations and Warranties. Affiliate represents and warrants to
  Parent as follows:

    (a) Affiliate is the holder and "beneficial owner" (as defined in Rule
  13d-3 under the Securities Exchange Act of 1934, as amended) of the number
  of shares of Company Common Stock set forth under Affiliate's signature
  below (the "Company Shares") and of options to purchase the number of
  shares of Company Common Stock set forth under Affiliate's signature below
  (the "Company Options"), and Affiliate has good and valid title to the
  Company Shares and the Company Options, free and clear of any liens,
  pledges, security interests, adverse claims, equities, options, proxies,
  charges, encumbrances or restrictions of any nature.

    (b) Affiliate has carefully read this Agreement, and has discussed with
  Affiliate's own independent counsel to the extent Affiliate felt necessary
  the limitations imposed on Affiliate's ability to sell, transfer or
  otherwise dispose of the shares of Parent Common Stock that Affiliate is to
  receive in the Merger (the "Parent Shares"). Affiliate fully understands
  the limitations this Agreement places upon Affiliate's ability to sell,
  transfer or otherwise dispose of the Parent Shares.

  2. Prohibition Against Transfer. In addition to the restrictions set forth
  elsewhere herein, Affiliate agrees that Affiliate shall not effect any
  sale, transfer or other disposition of the Parent Shares unless:

    (a) such sale, transfer or other disposition is made in conformity with
  the volume and other requirements of Rule 145 under the Securities Act, as
  evidenced by a broker's letter and a representation letter executed by
  Affiliate (reasonably satisfactory in form and content to Parent), each
  stating that such requirements have been met;

    (b) counsel reasonably satisfactory to Parent (it being understood that
  the law firm of Brobeck, Phleger & Harrison LLP is deemed to be reasonably
  satisfactory to Parent) shall have advised Parent in a written opinion
  letter (reasonably satisfactory in form and content to Parent), upon which
  Parent may rely, that such sale, transfer or other disposition will be
  exempt from registration under the Securities Act;

    (c) such sale, transfer or other disposition is effected pursuant to an
  effective registration statement under the Securities Act; or

    (d) an authorized representative of the SEC shall have rendered written
  advice to Affiliate to the effect that the SEC would take no action, or
  that the staff of the SEC would not recommend that the SEC take action,
  with respect to such proposed sale, transfer or other disposition, and a
  copy of such written advice and all other related communications with the
  SEC shall have been delivered to Parent.

  3. Stop Transfer Instructions; Legend. Affiliate acknowledges and agrees
  that (a) stop transfer instructions will be given to Parent's transfer
  agent with respect to the Parent Shares, and (b) each certificate
  representing any of such shares of Parent Common Stock or any substitutions
  thereof shall bear a legend (together with any other legend or legends
  required by applicable state securities laws or otherwise), stating in
  substance:

    THE SHARES REPRESENTED BY THIS CERTIFICATE WERE ISSUED IN A TRANSACTION
    TO WHICH RULE 145 PROMULGATED UNDER THE SECURITIES ACT OF 1933 APPLIES.
    THE SHARES REPRESENTED BY THIS CERTIFICATE MAY NOT BE OFFERED, SOLD OR
    OTHERWISE TRANSFERRED, ASSIGNED, PLEDGED OR HYPOTHECATED EXCEPT IN
    ACCORDANCE WITH THE PROVISIONS OF SUCH RULE AND IN ACCORDANCE WITH THE
    TERMS OF AN AGREEMENT DATED AS OF MAY 10, 1999, BETWEEN THE REGISTERED
    HOLDER AND QUANTUM CORPORATION, A COPY OF WHICH AGREEMENT IS ON FILE AT
    THE PRINCIPAL OFFICES OF QUANTUM CORPORATION.

  4. Permitted Transfers. Notwithstanding anything to the contrary contained
  in this Agreement, Affiliate may: (A) transfer shares of Company Common
  Stock prior to the Merger; (B) transfer shares of Parent Common Stock in
  payment of the exercise price of options to purchase Parent Common Stock;
  (C) transfer shares of Parent Common Stock to any organization qualified
  under Section 501(c)(3) of the Internal Revenue Code of 1986, as amended,
  so long as such organization has traditionally been supported by
  contributions from the general public (as opposed to being supported
  largely by a specific donor); and (D) transfer shares of Parent Common
  Stock to a trust established for the benefit of Affiliate and/or for the
  benefit of one or more members of Affiliate's family, or make a bona fide
  gift of shares of Parent Common Stock to one or more members of Affiliate's
  family, provided that in the case of a transfer or gift pursuant to this
  clause (C) or (D), a transferee of such shares agrees to be bound by the
  limitations set forth in this Agreement.

  5. Specific Performance. The parties agree that irreparable damage would
  occur in the event that any of the provisions of this Agreement was not
  performed in accordance with its specific terms or was otherwise breached.
  Affiliate agrees that, in the event of any breach or threatened breach by
  Affiliate of any covenant or obligation contained in this Agreement, each
  of Parent and Company shall be entitled (in addition to any other remedy
  that may be available to it, including monetary damages) to seek and obtain

                                      D-2
<PAGE>

  (a) a decree or order of specific performance to enforce the observance and
  performance of such covenant or obligation, and (b) an injunction
  restraining such breach or threatened breach.

  6. Independence of Obligations. The covenants and obligations of Affiliate
  set forth in this Affiliate Agreement shall be construed as independent of
  any other agreement or arrangement between Affiliate, on the one hand, and
  Company or Parent, on the other. The existence of any claim or cause of
  action by Affiliate against Company or Parent shall not constitute a
  defense to the enforcement of any of such covenants or obligations against
  Affiliate.

  7. Notices. Any notice or other communication required or permitted to be
  delivered under this Agreement shall be in writing and shall be deemed
  properly delivered, given and received when delivered (by hand, by

  confirmation) to the address or facsimile telephone number set forth
  beneath the name of such party below (or to such other address or facsimile

  8. Severability. If any provision of this Agreement or any part of any such
  provision is held under any circumstances to be invalid or unenforceable in
  any jurisdiction, then (a) such provision or part thereof shall, with
  respect to such circumstances and in such jurisdiction, be deemed amended
  to conform to applicable laws so as to be valid and enforceable to the
  fullest possible extent, (b) the invalidity or unenforceability of such
  provision or part thereof under such circumstances and in such jurisdiction

  governed in all respects by, the laws of the State of California (without
  giving effect to principles of conflicts of laws).

  10. Waiver. No failure on the part of Parent or Company to exercise any
  power, right, privilege or remedy under this Agreement, and no delay on the
  part of Parent or Company in exercising any power, right, privilege or
  remedy under this Agreement, shall operate as a waiver of such power,
  right, privilege or remedy; and no single or partial exercise of any such
  power, right, privilege or remedy shall preclude any other or further
  exercise thereof or of any other power, right, privilege or remedy. Neither
  Parent or Company shall be deemed to have waived any claim arising out of

  Agreement, unless the waiver of such claim, power, right, privilege or
  remedy is expressly set forth in a written instrument duly executed and
  delivered on behalf of the party deemed to be charged; and any such waiver

  14. Non-Exclusivity. The rights and remedies of Parent and Company
  hereunder are not exclusive of or limited by any other rights or remedies
  which Parent may have, whether at law, in equity, by contract or otherwise,
  all of which shall be cumulative (and not alternative). Nothing in this
  Agreement shall limit any of Affiliate's obligations, or the rights or
  remedies of Parent or Company, under any Voting Agreement (including any
  Irrevocable Proxy contained therein) or Noncompetition Agreement between
  Parent and Affiliate; and nothing in any such Voting Agreement (including

  Affiliate's obligations, or any of the rights or remedies of Parent, under
  this Agreement.

  15. Amendments. This Agreement may not be amended, modified, altered, or

  its rights under this Affiliate Agreement, in whole or in part, to any
  other person or entity without obtaining the consent or approval of

  obligations contained in this Agreement shall survive the consummation of
  the Merger.

Item 1. Business.

History

  For the purposes of this discussion, the term "PCI" shall refer to the
operations and business of Parallan Computer, Inc. prior to the acquisition of
Meridian Data, Inc. on December 1, 1994. The term "MDI" shall refer to the
operations and business of Meridian Data, Inc. prior to its acquisition by PCI.
Any reference to "Meridian" or the "Company" shall refer to the operations and

into a strategic alliance with International Business Machines Corporation
("IBM"). The strategic alliance with IBM encompassed certain product
development, manufacturing and support arrangements (the "Agreements"). PCI
granted IBM the exclusive rights to PCI's current and future products and
technologies in return for guaranteed minimum royalties in 1992 and 1993, and
revenue-based royalties for 1994 and beyond. The Agreements do not apply to any
technology acquired from or developed by MDI. After the first quarter of 1994,
sales by IBM of products licensed from PCI, net of returns, were zero. PCI
expected that this trend would continue for the foreseeable future. As a result
of management's expectations concerning future royalties from IBM, PCI
downsized and reorganized its operations into two segments: (i) developing
original equipment manufacturer ("OEM") relationships for its latest products
and (ii) focusing on potential acquisition opportunities. Over the course of
several months, PCI engaged in discussions with several large OEMs about the
sale or licensing of its latest server technology. These discussions ultimately
resulted in the sale of certain subsets of PCI's server technology for $1.5
million in the first quarter of 1995. PCI then narrowed its focus to
identifying potential acquisition candidates. On December 1, 1994, PCI acquired
all of the outstanding shares of MDI. MDI was a privately-held developer of
compact disc-read only memory ("CD-ROM") and compact-disc recordable ("CD-R")
systems and software for both networks and personal computers. With the
acquisition of MDI, PCI effectively ended its reliance on IBM as its primary
source of revenue. Since December 1, 1994, the Company's primary source of
revenue has derived from sales of the products of MDI. Thus, the remainder of
the discussion of the Company's business, industry, operations, or competition
under this Item will refer exclusively to the operations of Meridian.

Overview

  Meridian Data is a developer and manufacturer of network storage solutions
utilizing optical disk (CD-ROM) and conventional hard drive storage
technologies. The Company provides network attached storage servers ("NAS") for
workgroups based on optical disk and hard disk storage, and CD-ROM enterprise
networking servers and subsystems.

                                   Annex 1-2
<PAGE>

  During 1997, the Company also undertook the development of its first NAS
device based on hard drive technology. In March 1998, Meridian announced its
first NAS product based on hard drive technology, the Snap! Server(TM). The
Snap! Server allows small and medium-sized businesses and corporate workgroups
to increase storage capacity on their network with minimal hardware expertise
or time expenditure. The Company's Snap! Server is a time-efficient and cost-
effective alternative to the current methods of increasing network storage such
as installing an additional hard disk to an existing file server or purchasing
a new server primarily to increase storage on the network. Both of these
methods require more time and expense than the simple installation of a Snap!
Server. Another potential benefit of the Snap! Server is an increase in overall
network performance by offloading file serving duties from more expensive
application and general purpose servers and increasing network throughput by
placing data physically closer to the users who generate and/or need the data.
As an independent file server, the Snap! Server continues to provide file
services to network users even when the other servers are down.

  The Company's optical disk NAS servers allow workgroups within organizations
to simultaneously share up to 14 CD-ROM titles. The Company's CD-ROM enterprise
servers provide the same simultaneous access several hundred CD-ROM titles in
addition to providing a higher level of performance than Meridian's optical
disk NAS servers. Beginning in 1996, demand for the Company's enterprise
products began to decline due to a shift in large organizations towards web-
based data distribution. Meridian believes that this trend will continue for
the foreseeable future. Due to the decreasing demand for enterprise CD-ROM
servers, the Company refocused its research towards the development of NAS
servers. The Company released its CD-ROM NAS server in 1997. Since that time,
the Company's CD-ROM development efforts have been to maintain compatibility
with existing and developing hardware standards. For all its products, the
Company is committed to an open systems approach, supporting a broad array of
personal computer and network operating systems, and providing desktop access
to networked data, both CD-ROM and hard disk based, in heterogeneous
environments.

Industry Background

  CD-ROM Enterprise Servers and NAS Servers. Corporations and other
organizations that purchase information on CD-ROMs generally need to provide
multiple users with simultaneous access to information stored on those CD-ROMs.
These organizations require software specifically designed to enable them to
share CD-ROMs on a network, manage multiple titles and control user access.
Furthermore, corporations are following the trend of migrating to Microsoft
Windows NT from other network operating systems, and, as a result, CD-ROM
networking systems must be able to operate in heterogeneous environments during
this transition. When CD-ROMs are not networked, businesses must generally
purchase multiple copies of each CD-ROM set or physically transport discs
between desktop computers. Purchasing multiple copies is usually not as cost
effective as relying on site licenses, and physically transporting discs
between desktop computers can be time-consuming and can result in misplaced or
unreturned discs. In addition, many commercial databases are distributed on
multi-volume sets of discs that require physically shuffling discs if they are
used at a desktop computer with a single drive. As a result of these and other
factors, many organizations seek to implement networked, multi-drive CD-ROM
systems. Networked CD-ROMs can be quickly and easily accessed by multiple users
from their desktop computers. Because networked CD-ROMs are typically installed
on centrally managed servers, they can be efficiently managed and periodically
updated without access to individual desktop computers.

  Emerging Market for Hard Drive based Network Attached Storage for PC
LANs. The Company believes that with the increasing use of business software
suites, e-mail and internet applications, and rich data type software
applications, such as CAD and multimedia, corporations are experiencing a
dramatically increased need for network storage capacity. At the same time,
many small and medium-sized business are implementing PC LANs and lack the
internal technical expertise required to manage or upgrade their new networks.
Within larger organizations with in-house expertise, network managers find it
difficult to forecast future storage requirements and require the ability to
quickly and affordably increase network storage capacity. Hard drive-

                                   Annex 1-3
<PAGE>

based NAS servers are specialized file servers optimized for network data
storage. Unlike a general purpose server which handles a variety of tasks, from
running an intranet to managing e-mail to delivering mission-critical database
services, NAS products are optimized for data storage and efficiently manage
input/output traffic associated with that task, freeing up primary network
server resources for mission-critical applications, and enhancing speed on the
network by offloading data storage services. According to Dataquest, a leading
research firm focused on IT technology, the emerging market for NAS will grow
to $ 2.0 billion in 1999. In the past, hard drive-based NAS devices were
targeted primarily towards large Unix-based enterprise networks. By delivering
a PC LAN NAS device below $1,000, Meridian hopes to include many small and
medium-sized businesses, and corporate workgroups within the NAS market.

The Meridian Data Solution

  The Company offers a family of CD-ROM enterprise servers and NAS servers that
enable organizations to provide multi-user access over networks to centrally
managed data stored on either optical disks or hard drives. Meridian's
enterprise servers provide cost effective solutions for organizations with
applications or data on CD-ROM by eliminating the need to physically share
discs or purchase multiple copies of often expensive CD-ROM titles. The
Company's NAS products allow small and medium-sized businesses and workgroups
within a larger organization to implement networked CD-ROM or add additional
file storage capacity easily without network downtime and assistance from
third-party technical resources. The Company's products support a broad range
of networking environments, including Novell NetWare and Microsoft Windows NT,
and most popular PC desktop operating systems, including Windows 95/98, DOS,
OS/2. In addition, the Company's products are compatible with most major
network protocols.

The Meridian Data Strategy

  Meridian believes that customers want to implement "plug-and-play" storage
solutions for both CD-ROMs and network file servers. In response, the Company
introduced its CD Net Universal plug-and-play server in 1997 and its Snap!
Server in May 1998. In addition, the Company offers competitively priced CD-ROM
enterprise servers. The Company's goal is to be a leading provider of one-stop
shopping for plug and play network storage solutions utilizing CD-ROM and hard
drives. The key elements of the Company's strategy include:

    Focus on PC LAN NAS Devices. To meet the emerging demand for easily
  installed, plug-and-play storage products for small and medium-sized
  businesses and workgroups, Meridian offers NAS products based on both CD-
  ROM and hard drive technology. In May 1998, the Company premiered its first
  hard drive NAS product, the Snap! Server. This represented an entirely new
  product classification in the NAS market. Snap! Server is a protocol-
  independent, plug-and-play NAS server targeted for the PC LAN environment.
  Meridian does not believe that there is any competing product currently on
  the market that offers the same ease of use and installation as the Snap!
  Server. Initially, the Company expects that the main competition for the
  Snap! Server will be from traditional methods of increasing network
  storage. Such methods include purchasing new PC servers from vendors such
  as Compaq Computer Corporation ("Compaq"), and Dell Computer Corporation
  ("Dell"), and installing additional drives from manufacturers such as
  Seagate Technology, Inc. ("Seagate") and Maxtor Corporation ("Maxtor") in
  existing servers. The installation of additional drives or servers requires
  several hours of network downtime, often the services of a network
  professional, and the potential need for additional network operating
  software licenses, all of which adds to the overall cost of increasing
  storage on networks. The Company estimates that the cost of adding a
  comparable amount of additional storage to a PC server or network runs from
  approximately $3,000 to $10,000 or higher, depending on the server/network
  configuration, the need to purchase additional network software licenses,
  and network downtime. Meridian believes that its new Snap! Server has
  significant cost advantages over those competing methodologies for
  increasing network storage. The Company's Snap! Server retails for $1,795
  for 16 gigabytes and $995 for 8 gigabytes of storage capacity. Installation
  of the Snap! Server involves simply connecting the server to

                                   Annex 1-4
<PAGE>

  an Ethernet network port and power outlet. Setup and administration are
  managed via a simple HTML interface, accessed through an Internet browser,
  such as Netscape Navigator or Microsoft Internet Explorer.

    Support Industry Standards. Meridian believes that success in the NAS
  market requires products that are able to function in heterogeneous network
  environments. The Company's products operate over a broad range of desktop
  platforms, network operating systems, and connectivity protocols, and
  believes that this interoperability is core to a successful product
  strategy. The Company's products provide allows users to access data via
  standard tools and interfaces native to their network operating system
  environment. The Snap! Server is compatible with all major PC networks
  operating systems (Microsoft, Novell, and UNIX) and protocols (including
  TCP/IP, IPX, NetBEUI and HTTP) concurrently. In addition, it is able to
  work in heterogeneous network environments with the same ease as networks
  with a single network operating system. Failure to maintain such
  compatibility would have an adverse effect on the market's acceptance of
  the Snap! Server.

  Leverage Third-Party Distribution. The Company sells its products through
two-tier distribution, comprised primarily of large distributors of electronic
hardware and key value added resellers ("VARs"). The Company seeks to minimize
any conflict between third-party distribution and direct sales by fulfilling
orders through distributors and VARs, except in special circumstances dictated
primarily by customer requests.

Products

  Meridian provides support for a broad range of networking environments
(Novell NetWare and Microsoft Windows NT) and desktop operating systems
(Windows 95/98 and Windows 3.x, DOS, Macintosh and OS/2), and is compatible
with most major connectivity methodologies and network protocols. The table

Sales, Marketing and Customer Service

  The Meridian sales organization is divided into multiple North American
territories, Europe, the Middle East, Latin America, and the Pacific Rim.
Leading each region is a sales director responsible for managing the Company's
major distributors, direct sales of enterprise systems into major accounts, and
OEM sales. Each territory has an assigned sales representative, who is
responsible for developing marketing programs with all VARs in his or her
territory, developing new VAR relationships, and sales into smaller accounts
through the Company's VARs. A final level of sales support is provided by sales
engineers who provide technical assistance to sales staff in several
territories. The Company's workgroup products are marketed primarily through
advertising and the Company's established distribution channel. The Company
seeks to minimize any conflict between third party distribution and direct
sales by fulfilling orders through distributors and VARs, except in special
circumstances dictated primarily by customer requests. The Company's sales
personnel that are focused on the distribution channel work closely with the
Company's largest distributors to ensure that the proper level and mix of
inventory is maintained, and works with the distributor and VAR in developing
cooperative marketing programs for the Company's products.

  To support its sales efforts, the Company's marketing organization focuses on
increasing end user demand and creating awareness in the distribution channel
of the Company's products. The Company's marketing organization focuses on
educating end users and network professionals on the Company's simple, cost
effective solutions to increasing network storage via Snap! Servers and
accessing and sharing CD-ROMs. The Company's marketing program includes direct
mail, public relations, educational seminars, specialty trade shows, selected
joint marketing programs, advertising in leading industry publications such as
the PC Week, InfoWorld, PC Magazine, and Windows Magazine, and a home page on
the World Wide Web. The Company's sales and marketing organization consisted of
24 persons as of December 31, 1998.

  The Company began shipping its new Snap! Server in the second quarter of
1998. A key element in the success of the Snap! Server will be educating users
about the advantages of utilizing NAS technology for PC LANs. The failure by
the Company to successfully educate the market on the benefits of NAS,
especially its Snap! Server, would have a material adverse effect on Meridian's
business, financial condition and results of operations. The Snap! Server
requires different marketing, sales and distribution strategies than those for
the Company's enterprise products. As such, it entails significant new risks to
Meridian. There can be no assurance that the Company's distributors and VARs
will be able to effectively market this new product or that the Company will be
successful in establishing other modes of marketing, sales, and distribution. A
failure of the Company's distributors and VARs to successfully market this
product, or the failure to establish other means of marketing, sales, and
distribution, would have a material adverse effect on the Company's business,
financial condition and results of operations. See "Risk Factors--Dependence on
Third Party Distributors;--New Product Development;--Rapid Technological
Change; Potential for Product Defects;--Competition; emerging Markets; Product
Concentration."

  The Company's customer service department consisted of 7 persons as of
December 31, 1998. The Company's customer support department provides
installation and maintenance support via telephone, a Company bulletin board,
ftp file server, and Internet support on the World Wide Web at
http://www.meridian-data.com and http://www.snapserver.com. Meridian CD-ROM
products are sold with a one or three year warranty, which can be extended for
an additional fee. The Company's Snap! Server is sold with a 30-day money back
guarantee and a three year warranty.

Distribution

  Approximately 90% of the Company's product sales are derived from two-tier
sales to distributors and VARs. Because the Company derives such a significant
portion of its products through distributors and VARs, it is difficult for the
Company to determine the identity of the end user of the Company's products.
The Company's distribution channel consists of two North American distributors,
Ingram Micro, Inc. ("Ingram Micro") and Tech Data Corporation ("Tech Data").
Meridian's VARs generally concentrate their sales efforts

                                   Annex 1-6
<PAGE>

by region, or by industry, such as Government Technology Services, Inc.
European sales are currently the responsibility of a third-party manufacturer's
representative. The Company's systems are installed in numerous industries,
including government, education, law and accounting. The Company's typical
distribution agreement gives the distributor the right, under limited
circumstances, to return products. In addition, the Company allows price
protection to certain distributors and VARs, to the extent that they are
holding inventory at the time the Company announces a price decrease.

  Tech Data and Ingram Micro accounted for 41% and 23%, respectively, of the
Company's 1998 product sales. The loss of either of these distributors, or
certain other distributors or VARs, could have a material adverse effect on the
Company's business, financial condition and results of operations. Certain of
the Company's distributors and VARs also act as distributors for competitors of
the Company and could devote greater effort and resources to marketing
competitive products. In addition, effective distributors and VARs must possess
sufficient technical, marketing and sales resources and must often devote these
resources to a relatively lengthy sales cycle. There can be no assurance that
the Company's current distributors and VARs will be able to continue to market
the Company's existing or new products effectively or that economic conditions
or industry demand will not adversely affect such distributors and VARs. New
products may require a different marketing, sales and distribution strategies
than those for the Company's current products. There can be no assurance that
the Company's distributors and VARs will choose or be able to effectively
market these new products or to continue to market the Company's existing
products. A failure of the Company's distributors and VARs to successfully
market the Company's products would have a material adverse effect on the
Company's business, financial condition and results of operations. See "Risk
Factors--Dependence on Third Party Distributors."

Research and Development

  The Company's research and development staff consisted of 27 engineers as of
December 31, 1998. The Company's primary focus in 1998 was on the development
and enhancement of the current Snap! Server, additional products for inclusion
in the Snap! Server family of products, and maintaining compatibility with
evolving hardware standards for its CD-ROM products. There can be no assurance
that Meridian's research and development efforts will result in the successful
introduction any additional new products or that any of such products, if
developed, will be commercially successful. For a discussion of certain other
risks that may relate to the Company's research and development, see "Risk
Factors-Rapid Technological Change; Potential for Product Defects; and--New
Product Development."

  Meridian Data's systems sold after December 31, 1997 do not utilize calendar
dates. As such, the Company's software should have no difficulty with Year 2000
issues. Meridian's systems, however, are reliant on various network and
personal computer operating systems, such as MS-DOS, Novell NetWare, and
Microsoft Windows 3.11, Windows 95/98 and Windows NT. To the extent that those
vendors do not adequately solve their Year 2000 issues, the Company's products,
results of operations, cash flow, and liquidity may be adversely affected. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations--Year 2000 Issue."

Manufacturing

  The Company contracts with third parties to manufacture some of its products,
and also maintains a manufacturing facility onsite for enterprise-level
products. Finished products are distributed from the Scotts Valley facility to
customers. The Company is dependent on a small number of suppliers, some of
whom are located in Asia, for certain key components and parts used in its
products, including CD-ROM drives, microprocessors, integrated circuits and
power modules. In addition, certain subassemblies used in the Company's
products are manufactured by a single third-party vendor. Financial, market or
other developments adversely affecting the Company's key component suppliers,
the loss of a key subassembly manufacturer, or the loss of the contract
manufacture would have an adverse effect on their ability to supply the Company
with

                                   Annex 1-7
<PAGE>

components or assemblies and, consequently, would have a material adverse
effect upon the Company's business, financial condition and results of
operations. Although the Company believes that alternative sources of
components or assembly services could be arranged, the process of qualifying
new suppliers could be lengthy, could require re-engineering of the Company's
products, and there can be no assurance that any additional source would be
available to the Company on a timely basis or at a cost acceptable to the
Company. Any disruption or reduction in the future supply of any key components
currently obtained from limited sources would have a material adverse effect on
the Company's business, financial condition and results of operations. See
"Risk Factors--Dependence on Third Party Suppliers."

Competition

  The Company's Snap! Server competes with alternative methods of adding
storage to PC LAN networks, such as adding new PC servers from companies such
as Dell, Compaq and IBM, and adding additional disk drives from manufacturers
such as Seagate and Maxtor to existing servers. These companies in particular,
and the Company's competitors in general, include large domestic and
international companies, many of which have significantly greater financial,
technical, manufacturing, marketing, sales and distribution resources than the
Company. There can be no assurance that the Company's current or potential
competitors will not develop products comparable or superior to the Snap!
Server or adapt more quickly than the Company to new or emerging technologies,
evolving industry trends or changing customer requirements. Meridian's Snap!
Server requires customers to change the method in which they address the
problem of adding additional storage to their PC LAN networks. There can be no
assurance that the Company will be successful in educating the market on the
advisability of switching from adding additional drives to their servers or
additional servers to their PC LAN and using a Snap! Server in their place.

  The markets for the Company's products are extremely competitive, and the
Company expects that competition will increase as more companies enter the
market and as existing competitors continue to change and expand their product
offerings. Pricing is very aggressive in the Company's industry, and the
Company expects pricing pressures to continue to intensify. Many of the
Company's competitors have entrenched market positions, established patents,
copyrights, trade names, trademarks and intellectual property rights and
substantial technological capabilities. The Company's current competitors in
the CD-ROM storage market include other suppliers of CD-ROM networking software
and hardware such as Procom Technology. The Company also competes indirectly
with suppliers of personal computers and servers, like Hewlett Packard, Dell,
Compaq and IBM, and network operating systems, such as Microsoft and Novell, to
the extent such companies include CD-ROM networking utilities as part of their
operating systems. These companies in particular, and the Company's competitors
in general, include large domestic and international companies, many of which
have significantly greater financial, technical, manufacturing, marketing,
sales and distribution resources than the Company. There can be no assurance
that the Company's current or potential competitors will not develop products
comparable or superior to those developed by the Company or adapt more quickly
than the Company to new or emerging technologies, evolving industry trends or
changing customer requirements.

  The Company believes that its ability to compete successfully in the CD-ROM
networking and NAS markets will depend upon a number of factors both within and
outside of its control, including price, quality, product performance and
features; timing of new product introductions by the Company, its customers and
competitors; customer service and technical support; and the ability of the
Company to respond more quickly than current or potential competitors to new or
emerging technologies, evolving industry trends and changes in customer
requirements and to devote greater resources than current or potential
competitors to the development, promotion and sale of products. The Company
believes that it competes favorably with respect to these factors. There can be
no assurance however that the Company will have the financial resources,
technical expertise, or marketing, sales, distribution and customer service and
technical support capabilities to compete successfully.

                                  RISK FACTORS

  The following risk factors should be considered carefully in addition to the
other information presented in this report. This report contains forward-
looking statements within the meaning of Section 27A of the Securities Act of
1933, as amended, and Section 21G of the Securities Exchange Act of 1934, as
amended, that involve risks and uncertainties. The Company's actual results may
differ significantly from the results discussed in the forward-looking
statements. Factors that might cause such differences include, but are not
limited to, the following risk factors.

  Operating Losses; Fluctuations in Quarterly Operating Results. The Company
(then known as Parallan Computer, Inc.) fundamentally changed its business in
December 1994 with the purchase of Meridian Data, Inc. During 1994, the Company
exited its prior business and product line, which had generated substantial
losses. In the first half of 1995, the Company incurred an operating loss,
excluding certain non-recurring revenue. From that point the Company operated
profitably until the first quarter of 1997, when it again began incurring net
losses. The Company has failed to meet its expectations of future revenues in
the past and may not meet future expectations. As a result of these and other
factors, the Company believes that its revenues and operating results are
difficult to predict and are subject to fluctuations from period to period.
There can be no assurance that the Company will return to profitability, or
that if profitability is achieved, will be able to sustain profitability. In
order to address its disappointing systems revenue growth, Meridian increased
its sales and promotional expenditures in 1996 and, at the end of January 1997,
significantly reduced system prices in response to competitive pressures. Unit
shipments did not increase and there can be no assurance that prices for the
Company's products will not decrease further due to competitive pricing
pressures. Accordingly, the Company may not meet its total revenue goals and
the Company's business, financial condition and results of operations would be
materially adversely affected. As a result of expenses related to the
engineering and marketing campaign of Meridian's Snap! Server, the Company
anticipates that it will operate at a substantial net operating loss through
the end of 1999.

  The Company generally ships its software and systems within a short period
after receipt of an order, therefore the Company typically does not have a
material backlog of unfilled orders. Accordingly, total revenues in any quarter
are substantially dependent on orders booked in that quarter. This may result
in quarterly fluctuations in revenue. The Company's expense levels are based,
in part, on its expectations as to future sales. As a result, if sales levels
are below expectations, net income may be disproportionately affected. The
Company's quarterly operating results may also vary significantly depending on
other factors, including the introduction of new products by the Company's
competitors; market acceptance of the Company's new products; mix of software
and systems sales; adoption of new technologies and standards; price and other
forms of competition; the long and complex sales cycle for site licenses; the
timing of site license revenue; the cost, quality and availability of third
party components used in the Company's systems; changes in the Company's
distribution arrangements; and the inability of the Company to accurately
monitor end user demand for its products due to the sale of products through
distributors and VARs.

  In 1998, identifiable sales to federal governmental agencies accounted for
approximately 8% of the Company's product sales, and the Company anticipates
that such sales will continue to account for a significant percentage of the
Company's revenues for the foreseeable future. In the event that there is any
reduction or deferral in spending by such governmental agencies, the Company's
quarterly and annual results would be adversely affected. Similarly, if such
government agencies reduced their purchases of Meridian products in favor of
those of its competitors, the Company's quarterly and annual results would be
adversely affected. In the past, the Company's business has experienced
seasonality in the form of higher sales for its products during the quarters
ending in September and December and weaker sales during the quarters ending in
March and June. Due to the shift in the Company's revenues mix from enterprise
systems to NAS products, this trend is no longer evident. The Company's
operating results will also be affected by the economic condition of the
personal computer industry, which has from time to time experienced cyclical,
depressed business conditions, often in connection with or in anticipation of a
decline in general economic conditions. Due to all of the foregoing factors,
the Company's total revenues or operating results may in one or more future
quarters be

                                   Annex 1-9
<PAGE>

below the expectations of stock market analysts and investors. In such event,
the price of the Company's Common Stock would likely decline, perhaps
substantially. See "Management's Discussion and Analysis of Financial Condition
and Results of Operations."

  Product Concentration. The Company's future financial performance continues
to be contingent primarily on the success of, and growth in demand for NAS
products. The market for NAS appliances is new and undeveloped. There can be no
assurance that the Company's products will be widely accepted in this emerging
market. If demand for the Snap! Server, or other NAS devices, fails to develop,
or develops more slowly than the Company currently anticipates, the Company's
business, financial condition and results of operations would be materially
adversely affected. In addition, while there is a substantial installed base of
CD-ROM/DVD drives in the United States, growth in the CD-ROM/DVD networking
market is primarily in entry-level systems with low price points. There can be
no assurance that the Company's products will be widely accepted in this
market. If demand for the Company's CD-ROM/DVD networking products continues to
decrease, and demand for NAS products not develop, the Company's business,
financial condition and results of operations would be materially adversely
affected.

  Snap Server. The Company is actively developing additional products for its
Snap! Server family of products. This entails further expansion into non-CD-
ROM/DVD networking markets, in which the company has minimal experience. Such
entry entails substantially higher risks to the Company in the form of new and
well established competition, and competitive dynamics different than those
experienced in the CD-ROM/DVD networking market. In attempting to successfully
enter the NAS market and other new markets, the Company will have to commit to
significant levels of engineering, sales and marketing expenditures. With
respect to NAS, Meridian must also successfully educate the market concerning
the practicality of changing from conventional means of adding storage capacity
to PC networks to installing its Snap! Server, or related products. There can
be no assurance that the Company will be successful in marketing its Snap!
Server or other new products, that the Company will not experience difficulties
that could delay or prevent the successful development, introduction and
marketing of future Snap! Server products or other new products, or that its
Snap! Server or other new products will adequately meet the requirements of the
marketplace and achieve market acceptance. If the Company is unable, for
technological or other reasons, to develop and introduce current and future
Snap! Server products or other new products in a timely manner in response to
changing market conditions or customer requirements, the Company's business,
financial condition and results of operations will all be materially adversely
affected. The Company's potential new products likely will be subject to
significant technical risk due to their complexity and the difficulty in
gauging the engineering effort required to produce such products. There can be
no assurance that future Snap! Server products and other potential new products
will be introduced on a timely basis or at all. In addition, there can be no
assurance that the Company will be able to continue to offer the functionality
and ease-of-use that it believes future Snap! Server products require for a
successful introduction. If the new products are delayed, do not offer the
functionality and ease-of-use envisioned, or do not achieve market acceptance,
the Company's business, financial condition and operating results will be
materially adversely affected. As a result of uncertainty with respect to Snap!
Server revenues and anticipated expenses required to successfully develop and
market this product, the Company anticipates that it may operate at a
substantial net operating loss through the end of 1999.

  Dependence on New Distribution Channels. The Company anticipates that VARs,
catalogs, and business-to-business retailers will play a significant role in
its Snap! Server sales strategy. In addition, as the market for the Company's
CD-ROM/DVD products transition from enterprise-servers to workgroup-servers,
the Company anticipates that catalogs and business-to-business retailers will
account for an increasingly greater proportion of the Company's revenues. Early
in 1998, some of the Company's existing CD-ROM/DVD workgroup-server products
began utilizing the same new distribution channels as the Company's Snap!
Server, in addition to the Company's traditional channels, distributors, VARs
and direct sales/telemarketing. The Company must implement marketing strategies
designed to indirectly generate end-user demand thru such new distribution
channels. There can be no assurance that the Company will be able to
effectively design and

                                   Annex 1-10
<PAGE>

implement such strategies or that such strategies will be successful in
generating such end-user demand. The Company's agreements or purchase orders
with its catalog and business-to-business retailers typically allow for
extended payment terms and substantial rights of return. While the Company will
provide for a reserve for future returns, there can be no assurance that the
reserve will adequately cover actual product returns. Excessive or
unanticipated returns could materially adversely affect the Company's business,
financial condition and results of operations. The Company's business,
financial condition and results of operations could also be materially
adversely affected by changes in catalog or business-to-business retailers'
inventory strategies, which could occur rapidly, and may be unrelated to end
user demand. A failure of the Company's new distribution channels to
successfully market the Company's products would have a material adverse effect
on the Company's business, financial condition and results of operations. As a
result of the extended payment terms required by these customers, the Company's
liquidity may be adversely impacted by the timing of payments required by its
vendors preceding the receipt of payments from retail customers.

  Competition. Initially, the Company's Snap! Server will compete with
alternative methods of adding storage to PC LAN networks such as adding new PC
servers from companies such as Dell, Compaq, Hewlett Packard and International
Business Machines Corporation ("IBM"), adding additional disk drives from
manufacturers such as Seagate and Maxtor to existing servers, and potential new
competition from semiconductor manufacturers, such as Intel Corporation. These
companies in particular and others similar to them, and the Company's
competitors in general, include large domestic and international companies,
many of which have significantly greater financial, technical, manufacturing,
marketing, sales and distribution resources than the Company. There can be no
assurance that the Company's current or potential competitors will not develop
products comparable or superior to the Snap! Server or adapt more quickly than
the Company to new or emerging technologies, evolving industry trends or
changing customer requirements. There can be no assurance that the Company will
have the financial resources, technical expertise, or marketing, sales,
distribution and customer service and technical support capabilities to compete
successfully.

  The markets for the Company's CD-ROM/DVD products are extremely competitive.
The Company expects that competition will increase if more companies enter the
market and as existing competitors continue to change and expand their product
offerings. Pricing is very aggressive in the Company's industry, and the
Company expects pricing pressures to continue to intensify. The Company's
current competitors in the CD-ROM/DVD networking market include other suppliers
of CD-ROM/DVD networking software and hardware such as Procom Technology, Inc.,
and Hewlett Packard, Inc.. The Company also competes indirectly with suppliers
of personal computers, such as Dell, Compaq, and IBM, and network operating
systems such as Microsoft Corporation and Novell, Inc., to the extent such
companies include CD-ROM/DVD networking utilities as part of their operating
systems. The Company's potential competitors in the hardware area include
companies in the personal computer market and certain CD-ROM/DVD manufacturers.
These companies in particular, and the Company's competitors in general,
include large domestic and international companies, many of which have
significantly greater financial, technical, manufacturing, marketing, sales and
distribution resources than the Company. There can be no assurance that the
Company's current or potential competitors will not develop products comparable
or superior to those developed by the Company or adapt more quickly than the
Company to new or emerging technologies, evolving industry trends or changing
customer requirements. There can be no assurance that the Company will have the
financial resources, technical expertise, or marketing, sales, distribution and
customer service and technical support capabilities to compete successfully.

  The Company believes that its ability to compete successfully in the CD-
ROM/DVD networking and NAS markets will depend upon a number of factors both
within and outside of its control, including price, quality, product
performance and features; timing of new product introductions by the Company,
its customers and competitors; customer service and technical support; and the
ability of the Company to respond more quickly than current or potential
competitors to new or emerging technologies, evolving industry trends and
changes in customer requirements and to devote greater resources than current
or potential competitors to the development, promotion and sale of products.
The Company believes that it competes favorably with respect to these factors.

                                   Annex 1-11
<PAGE>

There can be no assurance however that the Company will have the financial
resources, technical expertise, or marketing, sales, distribution and customer
service and technical support capabilities to compete successfully.

  Dependence on Third Party Distributors. The Company derives substantially all
of its product sales through distributors, VARs, and retailers. Two
distributors accounted for 41% and 23%, respectively, of the Company's 1998
product sales. The loss of either of these distributors, or certain other
distributors, VARs, or retailers would have a material adverse effect on the
Company's business, financial condition and results of operations. The
Company's contractual relationships with its distributors, VARs, and retailers
can generally be canceled upon notice to the Company. Certain of the Company's
distributors, VARs, and retailers also act as distributors for competitors of
the Company and could devote greater effort and resources to marketing
competitive products. In addition, effective distributors, VARs, and retailers
must devote significant technical, marketing and sales resources to an often
lengthy sales cycle. There can be no assurance that the Company's current
distributors, VARs, and retailers will continue to market the Company's
products effectively or that economic or industry conditions will not adversely
affect such distributors, VARs, and retailers. Because the Company sells a
significant portion of its products through distributors, VARs, and retailers
it is difficult for the Company to monitor end user demand for its products on
a current basis. Initial stocking orders from distributors or retailers may not
be indicative of long-term end user demand. The Company's distributors and
retailers typically are allowed by contract to return products, subject to
certain limitations, without charge or penalty. While the Company provides for
a reserve for future returns, there can be no assurance that the reserve will
adequately cover actual product returns. Excessive or unanticipated returns
could materially adversely affect the Company's business, financial condition
and results of operations. The Company's business, financial condition and
results of operations could also be materially adversely affected by changes in
distributors' or retailers inventory strategies, which could occur rapidly, and
may be unrelated to end user demand. There can be no assurance that the
Company's distributors, VARs, and retailers will continue to market the
Company's existing products. A failure of the Company's distributors, VARs, and
retailers to successfully market the Company's products would have a material
adverse effect on the Company's business, financial condition and results of
operations.

  The Company began shipping its new Snap! Server in the second quarter of
1998. The Snap! Server requires different marketing, sales and distribution
strategies than those for the Company's current CD-ROM/DVD products. As such,
it entails significant new risks to Meridian. There can be no assurance that
the Company's distributors, VARs, and retailers will choose or be able to
effectively market this new product or that the Company will be successful in
developing alternate channels of distribution. Initial stocking orders from
distributors or retailers may not be indicative of long-term end user demand.
The Company's contracts with distributors and purchase orders from retailers
typically allow distributors and retailers of the Snap! Server and other new
products to return products, subject to certain limitations, without charge or
penalty. The Company provides for a reserve for returns based on its
contractual obligations. A failure of the Company's distributors, VARs, and
retailers to successfully market this product, or the failure to establish
other means of marketing, sales, and distribution, would have a material
adverse effect on the Company's business, financial condition and results of
operations.

  Dependence on Third Party Suppliers. The Company is dependent on a small
number of suppliers for certain key components used in its products, including
CD-ROM and DVD drives, microprocessors, integrated circuits and power modules.
The Company purchases these components pursuant to periodic purchase orders,
does not carry significant inventories of these components, and has no long-
term supply arrangements. In addition, certain subassemblies used in the
Company's products are manufactured by a single third party vendor. The loss of
a key supplier or a disruption to the business of a key supplier could have a
material adverse effect upon the Company's business, financial condition and
results of operations. Although the Company believes that alternative sources
of components or subassemblies could be arranged, the process of qualifying new
suppliers could be lengthy and could require substantial modification of the
Company's products to ensure compatibility. There can be no assurance that any
additional source would be available to the Company at all or on a timely basis
or at a cost acceptable to the Company. Any disruption or reduction or

                                   Annex 1-12
<PAGE>

termination in the future supply of any key components currently obtained from
limited sources could have a material adverse effect on the Company's business,
financial condition and results of operations. In the past, there has been
unexpected significant growth in the demand for CD-ROM/DVD drives, which has
caused temporary supply disruptions. These components are only available from a
limited number of manufacturers, most of which are Japanese manufacturers. The
Company has experienced in the past, and may experience in the future, an
adverse impact on the cost in dollars of certain components purchased from
Japanese manufacturers due to fluctuations in the exchange rate for the yen.
Moreover, the Company has been required to make spot market purchases for
certain components at premium prices. In the third quarter of 1995, the Company
experienced temporary delays in obtaining the drives required for its products.
If such delays reoccur or the Company is required to purchase components at a
higher cost due to fluctuating currency exchange rates, spot market shortages
or other factors, the Company may be unable to ship products on the schedule
anticipated or may sustain higher product costs with a resulting adverse effect
on the Company's business, financial condition and results of operations.

  The Company anticipates that the manufacturing of its new Snap! Server,
including final assembly and testing, will be contracted out to third party
vendors, some of whom may be located in Asia. Initially, Meridian will be
dependent on a few third party contractors. Like its CD-ROM/DVD counterparts,
the Snap! Server will be dependent on a small number of suppliers for certain
key components and parts, including microprocessors, integrated circuits and
power modules. In addition, certain subassemblies used will be manufactured by
a single third party vendor. Financial, market or other developments adversely
affecting the Company's key component suppliers, or the loss of a key
subassembly manufacturer, could have an adverse effect on their ability to
supply the Company with components or assemblies and, consequently, could have
a material adverse effect upon the Company's business, financial condition and
results of operations. The process of qualifying new suppliers or subassembly
manufacturers would be lengthy, and there can be no assurance that any
additional source would be available to the Company on a timely basis or at a
cost acceptable to the Company. Any disruption or reduction in the future
supply of any key components currently obtained from limited sources could have
a material adverse effect on the Company's business, financial condition and
results of operations

  Rapid Technological Change; Potential for Product Defects; and Obsolesce. The
market for the Company's products is characterized by rapid technological
advances, evolving industry standards in computer hardware and software
technology, changes in customer requirements and frequent new product
introductions and enhancements. The Company's future success will depend on its
ability to continue to enhance its current product line and to continue to
develop and introduce new products that keep pace with competitive product
introductions and technological developments, satisfy diverse and evolving
customer requirements and otherwise achieve market acceptance. There can be no
assurance that the Company will be successful in continuing to develop and
market on a timely and cost-effective basis new products or product
enhancements that respond to technological advances by others, or that these
products will achieve market acceptance. In addition, companies in the industry
have in the past experienced delays in the development, introduction and
marketing of new and enhanced products, and there can be no assurance that the
Company will not experience delays in the future. Any failure by the Company to
anticipate or respond adequately to changes in technology and customer
preferences, or any significant delays in product development or introduction,
would have a material adverse effect on the Company's business, financial
condition and results of operations.

  Due to their complexity and sophistication, the Company's products from time
to time may contain hardware or software defects or "bugs" which can be
difficult to correct. Furthermore, as the Company continues to develop and
enhance its products, there can be no assurance that the Company will be able
to identify and correct defects in a manner that will permit the timely
introduction of such products. Moreover, despite extensive testing, the Company
has from time to time discovered defects only after its products have been
commercially released. There can be no assurance that such defects will not
cause delays in product introductions and shipments or loss of or delay in
market acceptance, result in increased costs, require design modifications,
impair customer satisfaction, or result in customer returns. Any such event
could materially adversely affect the Company's business, financial condition
and results of operations.

                                   Annex 1-13
<PAGE>

  Over the past two years, CD-ROM/DVD drive technology has advanced
significantly. Additionally, the pace of new drive introductions has increased.
As a result, the Company may find itself holding an inventory of obsolete
drives. Further, the Company's contracts with its distributors and retailers
allow for product return, or price protection credits, based on their inventory
levels of current products and, under certain circumstances, obsolete products.
Meridian estimates and accrues its required allowance for such occurrences, but
there can be no assurance that actual inventory writedowns, product returns, or
price protection credits will not exceed the Company's estimate. Such an event
could materially adversely affect the Company's business, financial condition
and results of operations.

  Expansion of International Operations. There can be no assurance that the
Company will be able to successfully localize, market, sell and deliver its
products internationally. The inability of the Company to successfully expand
its international operations in a timely and cost effective manner could
materially adversely affect the Company's business, financial condition and
results of operations. International product sales were approximately 11% of
total product sales in 1998. The Company's business, financial condition and
results of operations could be materially adversely affected by risks inherent
in conducting business internationally, such as changes in currency exchange
rates, longer payment cycles, difficulties in staffing and managing
international operations, problems in collecting accounts receivable, slower
acceptance of technology advances compared with the United States, lack of
published CD-ROM/DVD content, seasonal reductions in business activity during
the summer months in Europe and certain other parts of the world, and tariffs,
duties and other trade barriers. For a discussion of the effect of fluctuations
in the exchange rate of the Japanese yen on the cost of certain components used
in the Company's products, see "Risk Factors--Dependence on Third Party
Suppliers."

  Dependence on Key Personnel; Management of Growth. Due to the specialized
nature of the Company's business, the Company's future success is highly
dependent upon the continued services of its key engineering personnel and
executive officers and upon its ability to attract and retain qualified
engineering, sales and marketing, management and manufacturing personnel for
its operations. Competition for such personnel is intense. There can be no
assurance that the Company will be successful in attracting or retaining such
personnel. The loss of any key personnel or the Company's inability to attract
and retain qualified employees could have a material adverse effect on the
Company's business, financial condition and results of operations. None of the
Company's key employees has an employment agreement with the Company, and the
Company does not maintain key man insurance policies on the lives of its key
employees. Although the Company's senior executives have lengthy experience in
the computer industry, they have no experience with the NAS market that the
Company has entered. To manage its growth, the Company must continue to
implement and improve its operational, financial and management information
systems and expand, train and manage its workforce. Meridian believes that
success in its industry requires substantial capital in order to maintain the
flexibility to take advantage of opportunities as they may arise. The Company
may, from time to time, as market and business conditions warrant, invest in or
acquire complementary businesses, products or technologies. Such investment or
acquisitions may be funded by internally generated cash, marketable securities,
debt, or the sale of additional equity. The sale of additional equity would
result in dilution in the equity ownership of Meridian's stockholders. The
Company's failure to manage growth effectively could have a material adverse
effect on the Company's business, financial condition and results of
operations.

  Employees. As of December 31, 1998, the Company employed 83 individuals, of
whom 13 were employed in manufacturing, 27 in research and development, 23 in
sales and marketing, 7 in customer support, 1 in product management, and 12 in
administration and finance. Competition in the recruiting of personnel in the
computer and networking industry is intense. The Company believes that its
future success will depend, in part, upon the continued services of its key
engineering personnel and executive officers and upon its ability to attract
and retain qualified engineering, sales and marketing, management and
manufacturing personnel for its operations. None of the Company's employees are
represented by a labor union or are subject to a collective bargaining
agreement. The Company believes that relations with its employees are good.

                                   Annex 1-14
<PAGE>

  To manage its growth, the Company must continue to implement and improve its
operational, financial and management information systems and expand, train and
manage its workforce. The Company's failure to manage growth effectively could
have a material adverse effect on the Company's business, financial condition
and results of operations. See "Risk Factors--Dependence on Key Personnel;
Management of Growth."

  Dependence on Proprietary Rights. The Company's success depends in part upon
protecting its proprietary technology. The Company relies on a combination of
intellectual property laws, nondisclosure agreements and other protective
measures to protect its proprietary information. There can be no assurance,
however, that the steps taken by the Company will be adequate to deter
misappropriation or independent third party development of its technology or
that its intellectual property rights can be successfully defended if
challenged. Litigation may be necessary to protect the Company's proprietary
rights. Any such litigation may be time-consuming and costly. In addition, the
laws of certain foreign countries do not protect the Company's intellectual
property rights to the same extent as the laws of the United States. Given the
rapid development of technology, there can be no assurance that certain aspects
of the Company's products do not or will not infringe upon the existing or
future proprietary rights of others or that, if licenses or rights are required
to avoid infringement, such licenses or rights could be obtained or obtained on
terms that are acceptable to the Company. The Company is not currently aware of
any infringement of its proprietary rights, nor is it aware of any claims that
its products infringe the rights of others.

  Possible Volatility of Stock Price. The Company believes that factors such as
announcements of developments related to the Company's business, announcements
by competitors, quarterly fluctuations in the Company's financial results,
conditions in the CD-ROM/DVD networking and NAS industries, changes in the
general economy and other factors could cause the price of the Company's Common
Stock to fluctuate, perhaps substantially. In addition, in recent years the
stock market in general, and the market for shares of small capitalization
technology stocks in particular, have experienced extreme price fluctuations,
which have often been unrelated to the operating performance of affected
companies. Such fluctuations could have a material adverse effect on the market
price of the Company's Common Stock.

  Anti-Takeover Effect of Stockholder Rights Plan and Certain Charter and Bylaw
Provisions. In July 1997, the Company's Board of Directors adopted a Preferred
Shares Rights Plan (the "Rights Plan"). The Rights Plan provides for a dividend
distribution of one Preferred Shares Purchase Right (a "Right") on each
outstanding share of the Company's Common Stock. The Rights will become
exercisable following the tenth day after a person or group announces
acquisition of 15% or more of the Company's Common Stock, or announces
commencement of a tender offer, the consummation of which would result in
ownership by the person or group of 15% or more of the Company's Common Stock.
The Company will be entitled to redeem the Rights at $0.01 per Right at any
time on or before the tenth day following acquisition by a person or group of
15% of more of the Company's Common Stock.

  The Rights Plan and certain provisions of the Company's Certificate of
Incorporation and Bylaws may have the effect of making it more difficult for a
third party to acquire, or of discouraging a third party from attempting to
acquire, control of the Company. The Company's Certificate of Incorporation
allows the Company to issue Preferred Stock without any vote or further action
by the stockholders, and certain provisions of the Company's Certificate of
Incorporation and Bylaws specify procedures for director nominations by
stockholders and submission of other proposals for consideration at stockholder
meetings, and eliminate cumulative voting in the election of directors. Certain
provisions of Delaware law could also delay or make more difficult a merger,
tender offer or proxy contest involving the Company, including Section 203,
which prohibits a Delaware corporation from engaging in any business
combination with any interested stockholder for a period of three years unless
certain conditions are met. The Rights Plan, the possible issuance of Preferred
Stock, the procedures required for director nominations and stockholder
proposals and Delaware law could have the effect of delaying, deferring or
preventing a change in control of the Company, including without limitation,
discouraging a proxy contest or making more difficult the acquisition of a
substantial block of the Company's Common Stock. These provisions could also
limit the price that investors might be willing to pay in the future for shares
of the Company's Common Stock.

  Potential Seismic Disturbances. The Company's research and development
activities, its corporate headquarters, other critical business operations and
certain of its suppliers are located near major earthquake faults. The ultimate
impact on the Company, its significant suppliers and the general infrastructure
is unknown, but operating results could be materially affected in the event of
a major earthquake. The Company is predominantly uninsured for losses and
interruptions caused by earthquakes.

Item 2. Properties.

  The Company leases its headquarters office and manufacturing facility in
Scotts Valley, California, under a noncancelable operating lease which expires
in December 1999. Other than several small regional sales offices, primarily
all of the Company's operations are conducted at the Scotts Valley location.
This facility is currently fully utilized. With respect to the Company's lease
expiring in 1999, management believes that the current lease could be
renegotiated or a suitable new location can be found at terms acceptable to the
Company.

Item 3. Legal Proceedings

  None.

Item 4. Submission of Matters to a Vote of Security-Holders.

  No matters were submitted to a vote of the Company's stockholders during the

          MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                           AND RESULTS OF OPERATIONS

  The words "anticipate," "believe," "estimate," "expect," "intend," "will,"
and similar expressions, as they relate to the Company or the Company's
management, including such items discussed in "Management's Discussion and
Analysis of Financial Condition and Results of Operations" set forth below, are
intended to identify forward-looking statements. Such statements reflect the
current views of the Company with respect to future events and are subject to
certain risks, uncertainties and assumptions. Should one or more of these risks
or uncertainties materialize, or should underlying assumptions prove incorrect,
actual results may vary significantly from those described.. In accordance with
provisions of Section 27A of the Securities Act of 1933, as amended, and
Section 21G of the Securities Exchange Act of 1934, as amended, we are making
investors aware that such forward-looking statements, because they relate to
future events, are by their very nature subject to many important factors which
could cause actual results to differ materially from those contained in the
forward-looking statements. Factors that might cause such differences include,
but are not limited to, the risk factors beginning on page 17.

General

  Prior to 1995, the Company (then known as Parallan Computer, Inc.) developed
and supported high performance network superservers. During 1994, the Company
exited its prior business and product line, which had generated substantial
losses. The Company fundamentally changed its business in December 1994 with
the purchase of Meridian Data, Inc. The total purchase price was $23.1 million.
The acquisition was accounted for using the purchase method of accounting and
included $21.2 million allocated to in-process research and development which
was charged to expense on December 1, 1994. Since the acquisition, the Company
has been developing and marketing network-attached storage (NAS") devices
utilizing both optical disk technology for the PC LAN environment, as well as
CD-ROM enterprise servers. In response to a decrease in the market for its CD-
ROM enterprise servers, Meridian embarked on the development of its first non-
CD-ROM NAS device, the Snap! Server, in late 1996 and shipped in May of 1998.
The Company believes that it will be several quarters before it achieves
significant revenues from sales of the Snap! Server. Meridian's expenses
related to product development and marketing related to the Snap! Server
resulted in the Company posting a substantial net operating loss for 1998 and
anticipating a loss for 1999. See "Risk Factors--New Product Development;--
Rapid Technological Change;--Potential for Product Defects; Competition;--
Emerging markets;--Product concentration." The Snap! Server is a protocol-
independent, NAS device targeted for the PC LAN environment. The Company
believes that the Snap! Server provides superior ease-of-use and installation
of any competitive product or competing method for adding storage to PC LAN
networks. The Company's Snap! Server retails for under $1,000. There can be no
assurance that the Company's current or potential competitors will not develop
products comparable or superior to the Snap! Server or adapt more quickly than
the Company to new or emerging technologies, evolving industry trends or
changing customer requirements. The Snap! Server requires different marketing,
sales and distribution strategies than those for the Company's current CD-ROM
products. There can be no assurance that the Company's distributors and VARs
will be able to effectively market this new product, nor that the Company will
be successful in developing alternate channels of distribution. Nor can there
be any assurance that the Snap! Server will be a commercial success. A failure
of the Company's distributors and VARs to successfully market the Company's new
products, or the failure to develop new channels of distribution, or the
failure to obtain market acceptance for the Snap! Server, would have a material
adverse effect on the Company's business, financial condition and results of
operations.

  Because the Company generally ships its products within a short period after
receipt of an order, the Company typically does not have a material backlog of
unfilled orders, and total revenues in any quarter are substantially dependent
on orders booked in that quarter. The Company's quarterly operating results may
also vary significantly depending on other factors, including the introduction
of new products by the Company's competitors; market acceptance of new
products; seasonality; mix of software and systems sales; adoption of

                                   Annex 1-25
<PAGE>

new technologies and standards; price and other forms of competition; the cost,
quality and availability of third party components used in the Company's
systems; changes in the Company's distribution arrangements; and the inability
of the Company to accurately monitor end user demand for its products due to
the sale of products through distributors and VARs. In 1998, 1997 and 1996,
identifiable sales to federal governmental agencies accounted for approximately
8%, 14% and 11%, respectively, of the Company's product sales, and the Company
anticipates that such sales will continue to account for a significant
percentage of the Company's revenues for the foreseeable future. In the event
that there is any reduction or deferral in spending by such governmental
agencies, the Company's quarterly results would be adversely affected.
Similarly, if such government agencies reduced their purchases of Meridian
products in favor of those of its competitors, the Company's quarterly results
would be adversely affected. The Company's operating results will also be
affected by the economic condition of the personal computer industry, which has
from time to time experienced cyclical, depressed business conditions, often in
connection with or in anticipation of a decline in general economic conditions.

Results of Operations

 Revenues

  Product sales. Meridian's product sales decreased to $17.5 million in 1998
from $20.0 million in 1997. This decrease was due to a continuing market driven
shift from enterprise-wide CD-ROM/DVD servers towards workgroup attached
storage products, such as CD Net Universal, which have increased in volume but
have lower average price points. This decrease was partially offset by sales of
the Snap! Server. Included in product sales for 1998 was approximately $2.7
million in sales related to the Company's new Snap! Server. The markets for
Meridian's products are extremely competitive, and the Company expects that
Meridian's revenue could be adversely impacted as new competitors enter the
market, existing competition continues to consolidate, change and expand
product offerings and react to prior market moves made by the Company, or Snap!
Server sales fail to continue their growth. Based on expected increases in
sales of the Company's workgroup products, Snap! Server and CD Net Universal,
Meridian believes that reported revenues in 1999 will be greater than those for
1998. The increase in Snap! Server sales assumes increasing market acceptance
of the Snap! Server. If that acceptance were not to develop, or to develop more
slowly than the Company anticipates, Meridian's results of operations and
liquidity would be adversely affected.

  Meridian's product sales decreased to $20.0 million in 1997 from $26.1
million in 1996. Meridian believes that the market for CD-ROM networking
systems fundamentally changed from one in which customers purchase integrated,
high-end CD-ROM enterprise servers, to one in which low-cost, plug and play CD-
ROM servers, such as Meridian's CD Net Universal, were in demand. Due to this
shift, Meridian's sales mix in 1997 shifted from its high-end enterprise
systems to its entry-level systems, such as the CD Net Universal server. Sales
from its low-end systems did not grow to the extent required to completely
offset lower sales of high-end systems. As such, revenues from the sale of
Meridian's CD-ROM networking products were less in 1998 than in 1997.

  Previously released software products favorably impacted the Company's sales
in 1996. Included in the Company's 1996 sales were approximately $330,000 from
the sale of two software site licenses. Beginning in the second quarter of
1996, and continuing throughout the remainder of the year, Meridian's revenue
mix shifted towards higher software content, and lower sales of systems. The
Company experienced increased price competition from its largest competitors
for its high-end system sales. As this trend continued, Meridian's revenue
growth slowed, while gross margin increased.

  Approximately 90% of the Company's product sales are derived from two-tier
distribution sales to distributors and VARs. Two distributors, Ingram Micro,
Inc. and TechData Corporation, accounted for 41% and 23%, respectively, of
Meridian's 1998 product sales. The loss of either of these distributors would
have a material adverse effect on the Company's results of operations. For a
discussion of certain other risks that may affect the Company's future product
sales, see "Risk Factors--Operating Losses; Fluctuations in Quarterly

Operating Results," "--Rapid Technological Change;--Potential for Product
Defects" and "--Emerging Markets; Product Concentration."

Gross margin

  Gross margin on product sales decreased to 42% in 1998 from 52% in 1997. This
was a result of the Company's transition to workgroup products like Snap!
Server and CD Net Universal from enterprise products. Meridian anticipates that
gross margins will decrease in 1999 due to the continued shift to workgroup
attached storage products, from the Company's enterprise storage products.
Gross margin decreased to 52% in 1997 from 61% in 1996 due to the price
reduction announced in January 1997, lower software sales, and a shift in the
Company's system mix to low-end systems.

  For a discussion of certain risks affecting cost of sales and gross margins,
see "Risk Factors--Dependence on Third Party Suppliers" and "--Expansion of
International Operations; Foreign Currency Fluctuations."

Operating expenses

 Research and development

  Research and development expense decreased in 1998 to $5.9 million from $6.3
million in 1997, a decrease of approximately $400,000. This decrease was due to
the completion of the development of the Snap! Server. Research and development
expense in 1997 was $6.3 million, an increase of approximately $3.0 million
over 1996. This increase was due to costs incurred in developing the Snap!
Server. The Company does not anticipate that research and development expenses
will continue to increase in 1999. Research and development expense in 1996 was
$3.3 million, an increase of $0.8 million over 1995. This increase was due to
higher payroll and overhead expenses, and the amortization of an advance made
to a development stage company ("DSC"). In June of 1997, DSC repaid the
advance. This was recorded as a credit against research and development
expense. Also included in the Company's research and development expense for
1997 was a $1.0 million charge for the acquisition of technology used in the
Snap!Server. This charge was offset by the receipt of the proceeds from the
advance.

  Research and development expense consists of salaries and related expenses
incurred in the development of the Company's products, as well as expenses
related to consultants and prototype material purchased in the development of
the Company's new products. For a discussion of certain risks related to
research and development, see "Risk Factors--Rapid Technological Change;
Potential for Product Defects."

 Sales and marketing

  Sales and marketing expense increased in 1998 by $2.5 million to $13.5
million due to product introduction and marketing costs related to the Snap!
Server. Sales and marketing expense consists primarily of payroll and related
expenses, including commissions, and advertising related expenses. Sales and
marketing expense in 1997 was $11.0 million, an increase of $3.5 million over
1996. This increase was primarily due to higher advertising and related
expenditures, increased payroll, and expenses related to marketing studies of
the NAS market. The Company does not expect that sales and marketing expenses
will increase in 1999. The new products, such as Snap! Server, require
different marketing, sales and distribution strategies than those for the
Company's current enterprise products. There can be no assurance that the
Company's distributors and VARs will be able to effectively market the new
network attached storage products or continue to market the Company's existing
products. Nor can there be any assurance that the Company will successfully
develop any such new channels for such products. A failure of the Company's
distributors and VARs to successfully market the Company's products, or the
failure to develop alternate channels of distribution for the Snap! Server,
would have a material adverse effect on the Company's business, financial
condition and results of operations.

                                   Annex 1-27
<PAGE>

  Sales and marketing expense was $7.5 million in 1996, an increase of
approximately $1.3 million, over 1995. This increase was due to higher payroll
and related expenses, and increased advertising and promotional expenses. The
increase in advertising and promotional expenses was primarily related to the
heightened competitive environment which began in early 1996.

  For a discussion of certain risks relating to sales and marketing, see "Risk
Factors--Dependence on Third Party Distributors" and "--Emerging Markets;
Product Concentration"; "--New Product Development."

 General and administrative

  General and administrative expense consists primarily of payroll and related
expenses and occupancy expenses. General and administrative expense was $2.6
million in 1998, $2.8 million in 1997 and $2.2 million in 1996. The decrease in
1998 was due to reduced legal costs. The Company does not anticipate that
general and administrative expenses will decrease in 1999. The increase between
1997 and 1996 was primarily due to higher payroll expenses and costs incurred
with the Company's reincorporation in Delaware.

Other income and expense

 Interest income and expense

  Interest income decreased in 1998 to $1.4 million from $2.0 million in 1997
due primarily to lower invested cash balances. The increase of interest income
in 1997 from 1996 was due to twelve months of interest earnings on funds
provided by a public offering of the Company's Common Stock in April of 1996.
Interest income increased to $1.6 million in 1996 due to a partial year's
earnings on the stock proceeds. Interest income will decrease in the future as
the Company expends funds for the marketing of its network attached server
product, Snap! Server.

Income taxes

  At December 31, 1998, the Company has a net operating loss carryforward for
U.S. federal and state income tax purposes of approximately $32.3 and $11.7
million, respectively, which expire between 1999 and 2018. The net operating
loss carryforwards include approximately $8.9 million of tax deductions
resulting from the exercise of employee stock options. The tax benefit of this
deduction, when realized, will be accounted for as a credit to stockholders'
equity rather than as a reduction in the income tax provision. The Company has
federal research and development tax credit carryovers of approximately $2.4
million at December 31, 1998 that expire in 2003 through 2012. The Company's
net operating losses, tax deductions and credit carryforwards may be limited by
changes in ownership as defined under the Internal Revenue Code of 1986, as
amended. Based on the Company's evaluation of the weight of available evidence
it can not conclude that it is more likely than not that deferred income tax
assets will be realized and therefore the Company has provided a full deferred
income tax valuation allowance at December 31, 1998.

Capital resources and liquidity

  Meridian's source of liquidity in 1998 was from cash and investments
available at December 31, 1997. The Company's negative cash flows from
operations in 1998 and 1997 were principally due to the net operating losses,
which included expenses related to the development and introduction of the
Snap! Server and an increase in inventory. Meridian's capital expenditures for
1998 were approximately $0.4 million. The Company's capital expenditures for
1997 were approximately $0.5 million. Meridian's source of cash flow from
operations for 1996 was principally net income from operations adjusted for
noncash depreciation and amortization charges and the amortization of an
advance for research and development arrangements. These were offset by an
increase in accounts receivable due to the timing of sales, and a decrease in
accounts payable and accrued payroll related expenses. The Company's capital
expenditures for 1996 were approximately $0.5 million.

  Meridian believes that success in its industry requires substantial capital
in order to maintain the flexibility to take advantage of opportunities as they
may arise. The Company may, from time to time, as market and

                                   Annex 1-28
<PAGE>

business conditions warrant, invest in or acquire complementary businesses,
products or technologies. The costs of such investments could be charged to
expense. Internally generated cash, marketable securities, debt, or the sale of
additional equity may fund such investment or acquisitions. The sale of
additional equity would result in dilution in the equity ownership of the
Company's stockholders, while the assumption of debt would increase the
Company's leverage, and consequently, its financial risk.

Year 2000 Issue

  The Year 2000 (Y2K) Issue refers to computer programs which use two digits
rather than four to define a given year and which therefore might read a date
using "00" as the year 1900 rather than the year 2000. The critical areas being
addressed by Meridian are its internal computer systems, products made by the
Company and relationships with external organizations. Meridian is addressing
both information technology ("IT") and non-IT systems, which typically include
embedded technology, such as microcontrollers. There are no known non-IT issues
that will adversely impact the Company's information systems or manufacturing
capabilities.

  Meridian considers a product to be "Y2K ready" if the product's performance
and functionality are unaffected by processing of dates prior to, during and
after the Year 2000, but only if the product and all of its component products
(for example hardware, software and firmware) properly exchange accurate date
data. The Company believes that its Snap! Servers, CD-ROM/DVD systems, and CD-
ROM/DVD networking software manufactured or released after December 31, 1997
are transparent to Year 2000 requirements, and rely primarily on software found
in operating systems and applications to function properly.

  The assessment of whether Meridian's software products will operate correctly
depends on the computer system and/or network on which the software is
installed. For many end-users this will include BIOS, software and components
provided by companies other than Meridian Data. After testing, the Company
believes its products manufactured or released after December 31, 1997 are Y2K
ready, although products manufactured or released prior to that date may not be
Y2K ready.

  In early 1999, the Company initiated formal communications with its
significant suppliers, contract manufacturers and financial institutions to
evaluate their Y2K compliance plans and state of readiness and to determine
whether any Y2K issues will impede the ability of such suppliers, contract
manufacturers, or financial institutions to continue to provide goods and
services to the Company. However, our suppliers, contract manufacturers, and
financial institutions are under no contractual obligation to provide such
information to the Company. Accordingly, the Company may not be able to
accurately evaluate the Y2K impact on its operations of products and services
delivered by these third parties. Meridian has established procedures to ensure
that products and internal systems from new suppliers are Y2K compliant. As a
general matter, Meridian is vulnerable to any failure by its key suppliers and
contract manufacturers to remedy their own Y2K issues, which could delay
shipments of essential components and systems, thereby disrupting or halting
the Company's manufacturing operations. Further, Meridian also relies upon
governmental agencies, utility companies, telecommunication service companies
and other service providers outside of the Company's control. There is no
assurance that such suppliers, governmental agencies, financial institutions,
or other third parties will not suffer business disruptions caused by a Y2K
issue, and there is little practical opportunity for Meridian to test or
require Y2K compliance from many of those large agencies, companies or
providers. Such failures could have a material adverse effect on the Company's
business, financial condition and results of operations. Commencing in 1999,
Meridian plans to develop a contingency plan designed to address problems which
might arise from the failure of its suppliers or contract manufacturers to
timely and adequately address their Y2K issues.

  To date, the Company has not incurred any costs related to assessment and
remediation of Y2K readiness. A formal budget has not been established, and the
cost to Meridian of achieving Y2K readiness is evolving; however, it is not
currently expected to have a material effect on the Company's business,
financial condition, or results of operations. During 1998, Meridian completed
the installation of upgraded computer software for the Company's financial,
accounting, inventory control, order processing and other management
information systems which the vendors maintain are Y2K ready.

                         NOTES TO FINANCIAL STATEMENTS

             FOR THE YEARS ENDED DECEMBER 31, 1998, 1997, AND 1996

Note 1. The Company

  Meridian Data, Inc. (the "Company" or "Meridian"), was incorporated in 1988
and is currently engaged in the development of network storage solutions for
Novell, Windows NT, and Banyan networking environments, and related client
software.

Note 2. Summary of Significant Accounting Policies

Cash, Cash Equivalents, and Marketable Securities

  Cash equivalents consist of highly liquid investment instruments purchased
with original maturities of three months or less. The carrying value of cash
and cash equivalents approximates their estimated fair market value. At
December 31, 1998 and 1997, the Company's marketable securities, consisting
primarily of government and corporate bonds, certificates of deposit and
commercial paper, are classified as available for sale and are reported at fair
market value based on quoted market prices, which approximates cost. Any
unrealized gains or losses recorded as a separate component of stockholders'
equity.

Concentration of Credit Risk

  Financial instruments which potentially subject the Company to concentrations
of credit risk consist principally of unsecured accounts receivable and
investments in government and high grade corporate bonds, certificates of
deposit, and commercial paper. The Company places its cash primarily in
investment accounts under professional management. The Company's investment
policy limits the amount of credit exposure to any one issuer. The Company's
investment policy also attempts to limit interest rate risk by restricting any
concentration of maturities. Meridian's accounts receivable are primarily
derived from sales to distributors and value added resellers (VARs) in the
United States. The Company performs ongoing credit evaluations of its
customers' financial condition and maintains an allowance for uncollectible
accounts based upon the expected collectibility of all accounts receivable and
has not experienced material losses to date. At December 31, 1998, two
customers accounted for 66% of the Company's gross accounts receivables. At
December 31, 1997 two customers accounted for 44% of the Company's gross
accounts receivable.

Inventories

  Inventories are valued at the lower of cost, using the first-in first-out
method, or market.

Research and Development Costs

  The Company charges research and development costs to operations as incurred.
Statement of Financial Accounting Standards No. 86 "Accounting for Costs of
Computer Software to be Sold, Leased, or Otherwise Marketed" requires
capitalization of certain software development costs after technological
feasibility of software is established upon the completion of the working
model. Development costs incurred by the Company after completion of the
working model and prior to commercial release have been insignificant and all
software development costs since 1993 have been expensed as incurred.

Property and Equipment

  Property and equipment, including leasehold improvements, are stated at cost.
Depreciation and amortization is computed using the straight-line method over
the estimated useful lives of the assets, generally one to three and a half
years. Amortization of leasehold improvements is computed using the shorter of

             FOR THE YEARS ENDED DECEMBER 31, 1998, 1997, AND 1996


Income Taxes

  Income taxes are computed using the asset and liability method. Under this
method, deferred income tax assets and liabilities are determined based on the
differences between the financial reporting and tax bases of assets and
liabilities and are measured using currently enacted tax rules and laws.

Revenue Recognition

  Product revenues are recognized upon shipment to the customer or delivery to
a third party shipper. Revenue from sales to distributors is recognized net of
an allowance for product returns, price protection, and other adjustments which
may be required under the Company's agreements with distributors.

  During 1998, two customers, consisting of large distributors, accounted for
41% and 23% of Meridian's 1998 product sales. During 1997, two customers,
consisting of large distributors, accounted for 21% and 19% of the company's
1997 product sales. During 1996, two customers, consisting of large
distributors accounted for 25% and 18% of Meridian's 1996 product sales. There
are no reporting segments to disclose under FAS 131.

Basic and Diluted Net Income (Loss) Per Share

  The Company adopted Statement of Financial Accounting Standards No. 128,
"Earnings per Share" ("SFAS 128") during the year ended December 31, 1997 and
retroactively restated all prior periods under SFAS 128. Basic net income
(loss) per share is computed using the weighted average number of common shares
outstanding during the period. Diluted net income (loss) per share is computed
using the weighted average number of common and potential common shares during
the period. Potential common shares consist of the incremental shares issuable
upon the exercise of stock options (using the treasury stock method). Potential
common shares are excluded from the computation if their effect is anti-
dilutive. Options to purchase 2,145,309 shares of common stock at prices
ranging from $0.03 to $15.13 per share were outstanding during the year ended
December 31, 1998 but were not included in the computation of diluted EPS
because the options would have been antidilutive.

Use of estimates

  The preparation of financial statements in accordance with generally accepted
accounting principles requires management to make estimates and assumptions
that affect the reported amounts of assets and liabilities, disclosures of
contingent assets and liabilities at the date of the financial statements and
the reported revenue and expenses during the period. Actual results could
differ from estimates.

Bank Credit Facilities

  On October 14, 1998 the Company signed a credit agreement (the "Facility")
with a bank (the "Bank") for a $7.5 million revolving credit line which expires
on July 30, 1999. Borrowing under the Facility is at the Bank's prime rate plus
1/4 %, and is subject to the Company maintaining certain leverage ratios and
net worth requirements. All advances under the Facility must be repaid by the
expiration date of July 30, 1999. As of December 31, 1998, Meridian has no
amounts due under the Facility.

Recent Accounting Pronouncements

 Comprehensive Income

  There are no components of comprehensive income which are not included in the
Company's net income (loss).

1995 Director Stock Option Plan

  The Company has reserved 100,000 of Common Stock for issuance under the
Company's 1995 Director stock option plan (the "1995 Plan"). The 1995 Plan

shares of the Company's common stock to each outside Director upon their
initial election to the Board of Directors (the "First Option"). Upon each
subsequent re-election to the Board, the outside Director receives an
additional grant to purchase 5,000 shares of the Company's common stock (the
"Subsequent Option"). All options are granted at fair market value of the
Common Stock on the date of grant.

  The 1995 Plan provides that the First Option vests at the rate of 25% per
year on the anniversary of the grant date. Each Subsequent Option vests ratably
over eight months following the month of grant.

  Stock option activity under the above Plans for years 1998, 1997, and 1996,

to a new vesting schedule. Options for the purchase of a total of 366,184
shares were amended. On October 27, 1998, the Board of Directors approved an
offer to all employees, except certain executives, permitting an election to
amend their options to change the exercise price to the fair market value of
the Company's common stock on November 9, 1998, which was $1.56, subject to a
new vesting schedule. Options for the purchase of a total of 723,309 shares
were amended. At the same time, the Board of Directors approved an offer to
certain executives permitting an election to amend their options to change the
exercise price to the fair market value of the Company's common stock on
October 28, 1998, which was $1.44. Options for the purchase of a total of
1,069,413 shares were amended.

1992 Employee Stock Purchase Plan

  In October 1992, the Company adopted the 1992 Employee Stock Purchase Plan
(Purchase Plan). Under the Purchase Plan, an eligible employee may purchase
shares of Common Stock from the Company through payroll deductions of up to 10%
of their base compensation plus commission, at a price per share equal to 85%
of the fair market value as of the first day or the last day, whichever is
lower, of each six-month offering period under the Purchase Plan. The offering
periods commence on May 1 and November 1. The Company has reserved 400,000
shares of Common Stock for issuance under the Purchase Plan. At December 31,
1998, 346,562 shares of Common Stock had been issued under the Purchase Plan,
and 53,438 shares remain available for future issuance under the Purchase Plan.

Stock Compensation

  The Company accounts for its employee stock option plans in accordance with
the provisions of Accounting Principles Board Opinion No. 25. In October 1995,
the Financial Accounting Standards Board issued Statement of Financial
Accounting Standards No. 123 ("FAS 123"), "Accounting for Stock-Based
Compensation " which established a fair value based method of accounting for
employee stock option plans. The Company elected to adopt the disclosure method
of FAS 123. Had compensation cost for the Company's option plans been
determined based on the fair value at the grant dates, as prescribed in FAS
123, the Company's pro forma net income (loss) and pro forma diluted net income
(loss) per share would have been as follows:

Preferred Share Purchase Rights

  At December 31, 1998, there were outstanding 8,134,156 rights to purchase
Series A Participating Preferred Stock ("Preferred Stock"). The rights were
issued as a dividend on August 25, 1997 to stockholders of record as of the
close of business on that date. Each right entitles the holder to purchase from
the Company a unit (one one-thousandth) of Preferred Stock at $30 per unit
subject to adjustment. The rights are not exercisable or transferable apart
from the common stock until 10 days after a person or group (a) acquires
beneficial ownership of 15% or more of the Company's common stock or (b)
announces a tender or exchange offer, the consummation of which would result in
ownership by a person or group of 15% or more of the Company's common stock.
Each right will entitle the holder, under certain circumstances (acquiring
person becomes the beneficial owner of 15% or more of the Company's common
shares outstanding, merger or sale of 50% or more of the Company's consolidated
assets), to acquire, at half the value, common stock of the Company or common
stock of the acquiring person. The rights expire August 11, 2007 and are
redeemable prior to the time an acquiring person acquires 15% or more of the
Company's common stock at one cent per right. At December 31, 1998, 5,000,000
shares of Preferred Stock were authorized but unissued and were reserved for
issuance upon exercise of the rights.

  At December 31, 1998, the Company has a net operating loss carryforward for
U.S. federal and state income tax purposes of approximately $32.3 and $11.7
million, respectively, which expire between 1999 and 2018. The net operating
loss carryforward includes approximately $8.9 million of tax deductions
resulting from the exercise of employee stock options. The tax benefit of this
deduction, when realized, will be accounted for as a credit to stockholders'
equity rather than as a reduction in the income tax provision. The Company has
federal research and development tax credit carryovers of approximately $2.4
million at December 31, 1998, that expire in 2003 through 2012. The Company's
net operating losses, tax deductions and credit carryforwards

may be limited by changes in ownership as defined under the Internal Revenue
Code. Based on the Company's evaluation of the weight of available evidence it
can not conclude that it is more likely than not that deferred income tax
assets will be realized and therefore the Company has provided a full deferred
income tax valuation allowance at December 31, 1998.

Note 8. Related Party Transactions

  In connection with the Company's stock offering on April 30, 1996, Meridian
entered into an agreement to acquire and exercise an option held by IBM to
purchase 1,229,932 shares of outstanding Common Stock from certain stockholders
of the Company, including Bass Associates, an original investor in the Company.
Pursuant to the closing of the offering, Meridian exercised the option and
acquired 1,229,932 shares of Common Stock, including 66,544 shares from Bass
Associates, for $11.396 per share. Dr. Bass, General Partner of Bass Associates
and Chairman of the Board of Meridian Data, Inc., disclaims beneficial
ownership of the shares held by Bass Associates, except to the extent of his
proportional interest therein. The shares acquired were immediately retired.

Note 9. Employee Benefit Plans

  The Company has available to all full-time employees a retirement plan. Under
the plan, employee and employer contributions and accumulated plan earnings
qualify for favorable tax treatment under Section 401(k) of the Internal
Revenue Code, as amended. Meridian matches employee contributions dollar-for-
dollar, up to six percent of gross pay, with an annual cap of $1,200 per
employee.

                         NOTES TO FINANCIAL STATEMENTS
         For The Three Months Ended March 31, 1999, and March 31, 1998

Note 1. General

  The accompanying financial information is unaudited, but, in the opinion of
management, reflects all adjustments (which include only normally recurring
adjustments) necessary to present fairly the financial position of Meridian
Data, Inc. (the "Company") as of the dates indicated and the results of
operations for the periods then ended. 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 the rules and regulations of the Securities and Exchange
Commission. While the Company believes that the disclosures are adequate to
make the information presented not misleading, the financial information should
be read in conjunction with the audited financial statements, and notes
thereto, for the year ended December 31, 1998, included in the Company's Form
10-K. Results for the interim period are not necessarily indicative of the
results for the entire year.

Note 2. Income taxes

  The Company made no provision for income taxes in the first quarter of 1999
due to the net operating losses. The Company computes income taxes using the
asset and liability method. Under this method, deferred income tax assets and
liabilities are determined based on the differences between the financial
reporting and tax bases of assets and liabilities and are measured using
currently enacted tax rules and laws. Based on the Company's evaluation of the
weight of available evidence it can not conclude that it is more likely than
not that deferred income tax assets will be realized and therefore the Company
has provided a full deferred income tax valuation allowance at March 31, 1999.

Item 2. Management's Discussion and Analysis of Financial Condition and Results
of Operations.

  The words "anticipate," "believe," "estimate," "expect," "intend," "will,"
and similar expressions, as they relate to the Company or the Company's
management, including such items discussed in "Management's Discussion and
Analysis of Financial Condition and Results of Operations" set forth below, are
intended to identify forward-looking statements. Such statements reflect the
current views of the Company with respect to future events and are subject to
certain risks, uncertainties and assumptions. Should one or more of these risks
or uncertainties materialize, or should underlying assumptions prove incorrect,
actual results may vary significantly from those described. In accordance with
provisions of Section 27A of the Securities Act of 1933, as amended, and
Section 21G of the Securities Exchange Act of 1934, as amended, we are making
investors aware that such forward-looking statements, because they relate to
future events, are by their very nature subject to many important factors which
could cause actual results to differ materially from those contained in the
forward-looking statements. Factors that might cause such differences include,
but are not limited to, the risk factors beginning on page 10.

General

  The Company develops and markets network-attached storage (NAS") devices
utilizing both optical disk and conventional hard drive technologies for the PC
LAN environment, as well as CD-ROM enterprise servers. In response to a
decrease in the market for its CD-ROM enterprise servers, Meridian embarked on
the development of its first non-CD-ROM NAS device, the Snap! Server, in late
1996. The Company shipped its first Sanp! Server in May of 1998. The Company
believes that it will be several quarters before it achieves significant
revenues from sales of the Snap! Server. Meridian's expenses related to product
development and marketing of the Snap! Server resulted in the Company posting a
substantial net operating loss for 1998 and the Company anticipates a loss for
1999. See "Risk Factors--New Product Development;--Rapid Technological
Change;--Potential for Product Defects; Competition;--Emerging markets;--
Product concentration." The Snap! Server is a protocol-independent, NAS device
targeted for the PC LAN environment. The Company believes that the Snap! Server
provides superior ease-of-use and installation of any competitive product or
competing method for adding storage to PC LAN networks. The Company's Snap!
Server retails for under $1,000. There can be no assurance that the Company's
current or potential competitors will not develop products comparable or
superior to the Snap! Server or adapt more quickly than the Company to new or
emerging technologies, evolving industry trends or changing customer
requirements. The Snap! Server requires different marketing, sales and
distribution strategies than those for the Company's CD-ROM products. There can
be no assurance that the Company's distributors and VARs will be able to
effectively market the Snap! Server, nor that the Company will be successful in
developing alternate channels of distribution. Nor can there be any assurance
that the Snap! Server will be a commercial success. A failure of the Company's
distributors and VARs to successfully market the Company's new products, or the
failure to develop new channels of distribution, or the failure to obtain
market acceptance for the Snap! Server, would have a material adverse effect on
the Company's business, financial condition and results of operations.

  Because the Company generally ships its products within a short period after
receipt of an order, the Company typically does not have a material backlog of
unfilled orders, and total revenues in any quarter are substantially dependent
on orders booked in that quarter. The Company's quarterly operating results may
also vary significantly depending on other factors, including the introduction
of new products by the Company's current and potential new competitors; market
acceptance of new products; seasonality; mix of software and systems sales;
adoption of new technologies and standards; price and other forms of
competition; the cost, quality and availability of third party components used
in the Company's systems; changes in the Company's distribution arrangements;
and the inability of the Company to accurately monitor end user demand for its
products due to the sale of products through distributors and VARs. In 1998,
identifiable sales to federal governmental agencies accounted for approximately
8% of the Company's product sales, and the Company anticipates that such sales
will continue to account for a significant percentage of the Company's revenues
for the foreseeable future. In the event that there is any reduction or
deferral in spending by such governmental agencies, the Company's quarterly
results would be adversely affected. Similarly, if such government agencies

                                   Annex 2-6
<PAGE>

reduced their purchases of Meridian products in favor of those of its
competitors, the Company's quarterly results would be adversely affected. The
Company's operating results will also be affected by the economic condition of
the personal computer industry, which has from time to time experienced
cyclical, depressed business conditions, often in connection with or in
anticipation of a decline in general economic conditions.

Results of operations

Revenues

 Product sales

  Meridian's revenues increased to $4.1 million in the first quarter of 1999
from $3.3 million in the comparable period of 1998, an increase of 24%.
Included in revenues for the first quarter of 1999 was approximately $1.7
million related to the Snap! Server. Future increases in Snap! Server revenues
will be dependent on increasing market acceptance of Snap! Server technology.
If this acceptance were not to develop, or to develop more slowly than the
Company anticipates, Meridian's results of operations and liquidity would be
adversely affected. The Company does not have a material backlog of orders for
the Snap! Server or its other products and total revenues in any quarter are
substantially dependent on orders booked in that quarter. The markets for
Meridian's products are extremely competitive, and the Company expects that
competition will continue to increase as existing competitors consolidate,
change and expand their product offerings, and as new competitors enter the
market for NAS.

  For a discussion of certain other risks that may affect the Company's future
product sales, see "Risk Factors--Operating losses; Fluctuations in Quarterly
Operating Results," "--Rapid Technological Change; --Potential for Product
Defects" and "--Emerging Markets; Product Concentration."

Gross Margin

  Gross margin on product sales decreased to 36% in the first quarter of 1999
from 47% for the comparable period of 1998. Meridian expects gross margins to
continue to decrease in 1999 due to the continued shift to NAS products from
the Company's enterprise storage systems.

  For a discussion of certain other risks that may affect the Company's future
cost of product sales, see "Risk Factors--Dependence on Third party Suppliers"
and "--Expansion of International Operations; Foreign Currency Fluctuations."

Operating Expenses

 Research and development

  Research and development expense decreased in the first quarter of 1999 to
$1.1 million, from $1.6 million for the first quarter of 1998. This decrease
was due to the completion of the development, in 1998, of the the Snap! Server.
The Company does not anticipate that research and development expenses in 1999
will be greater than the corresponding periods of 1998.

  The Company's inability to anticipate and respond to technological and market
changes or Meridian's failure to incorporate new technologies in a timely
manner could have a material adverse effect on the Company's business,
financial condition and results of operations. In addition, there can be no
assurance that Meridian's research and development efforts will result in the
introduction of new products or that any of such products, if developed, will
be commercially successful. For a discussion of certain other risks that may
relate to the Company's research and development, see "Risk Factors--Rapid
Technological Change; Potential for Product Defects."

                                   Annex 2-7
<PAGE>

 Sales and marketing

  Sales and marketing expense increased by $0.8 million in the first quarter of
1999 to $2.7 million, from $1.9 million for the comparable period of 1998. This
increase was due to marketing costs related to the Snap! Server, introduced in
the second quarter of 1998. Sales and marketing expense consists primarily of
payroll and related expenses (including commissions), and promotional expenses.
The Company does not anticipate that sales and marketing expenses in 1999 will
be greater than the corresponding periods of 1998.

  There can be no assurance that Meridian's sales and marketing efforts will
result in the successful introduction of new products or that any of such
products, if developed, will be commercially successful. For a discussion of
certain other risks that may relate to the Company's sales and marketing, see
"Risk Factors--Dependence on Third Party Distributors" and "Product
Concentration."

 General and administrative

  General and administrative expenses consist primarily of payroll, payroll
related expenses and occupancy expenses. General and administrative expense was
$681,000 in the first quarter of 1999 and $644,000 in the first quarter of
1998. The Company anticipates that general and administrative expenses for 1999
will be greater than the corresponding periods of 1998.

 Interest income

  Interest income decreased to $200,000 in the first quarter of 1999 from
$402,000 in the first quarter of 1998 primarily due to lower invested cash
balances. Interest income will continue to decrease as the Company expends
funds for product development and marketing and other corporate purposes.

 Income taxes

  The Company made no provision for income taxes in the first quarter of 1999
due to the net operating losses. The Company computes income taxes using the
asset and liability method. Under this method, deferred income tax assets and
liabilities are determined based on the differences between the financial
reporting and tax bases of assets and liabilities and are measured using
currently enacted tax rules and laws. Based on the Company's evaluation of the
weight of available evidence it can not conclude that it is more likely than
not that deferred income tax assets will be realized and therefore the Company
has provided a full deferred income tax valuation allowance at March 31, 1999.

Capital resources and liquidity

  Meridian's negative cash flow from operations for the first three months of
1999 was principally due to the net operating loss of $2.8 million, and an
increase in inventory. At March 31, 1999, the Company's principal source of
liquidity consisted of cash and marketable securities totaling $15.4 million,
and accounts receivable of $5.5 million. Meridian believes that its current
cash, marketable securities, and accounts receivable will satisfy its working
capital needs and capital expenditures for at least the next twelve months.

  Meridian believes that success in its industry requires substantial capital
in order to maintain the flexibility to take advantage of opportunities as they
may arise. The Company may, from time to time, as market and business
conditions warrant, invest in or acquire complementary businesses, products or
technologies. The costs of such investments could be charged to expense. Such
investment or acquisitions may be funded by internally generated cash,
marketable securities, or the sale of additional equity. The sale of additional
equity would result in dilution in the equity ownership of the Company's
stockholders.

Year 2000 Issue

  The Year 2000 (Y2K) Issue refers to computer programs which use two digits
rather than four to define a given year and which therefore might read a date
using "00" as the year 1900 rather than the year 2000. The

                                   Annex 2-8
<PAGE>

critical areas being addressed by Meridian are its internal computer systems,
products made by the Company and relationships with external organizations.
Meridian is addressing both information technology ("IT") and non-IT systems,
which typically include embedded technology, such as microcontrollers. There
are no known non-IT issues that will adversely impact the Company's information
systems or manufacturing capabilities.

  Meridian considers a product to be "Y2K ready" if the product's performance
and functionality are unaffected by processing of dates prior to, during and
after the Year 2000, but only if the product and all of its component products
(for example hardware, software and firmware) properly exchange accurate date
data. The Company believes that its Snap! Servers, CD-ROM/DVD systems, and CD-
ROM/DVD networking software manufactured or released after December 31, 1997
are transparent to Year 2000 requirements, and rely primarily on software found
in operating systems and applications to function properly.

  The assessment of whether Meridian's software products will operate correctly
depends on the computer system and/or network on which the software is
installed. For many end-users this will include BIOS, software and components
provided by companies other than Meridian Data. After testing, the Company
believes its products manufactured or released after December 31, 1997 are Y2K
ready, although products manufactured or released prior to that date may not be
Y2K ready.

  In early 1999, the Company initiated formal communications with its
significant suppliers, contract manufacturers and financial institutions to
evaluate their Y2K compliance plans and state of readiness and to determine
whether any Y2K issues will impede the ability of such suppliers, contract
manufacturers, or financial institutions to continue to provide goods and
services to the Company. However, our suppliers, contract manufacturers, and
financial institutions are under no contractual obligation to provide such
information to the Company. Accordingly, the Company may not be able to
accurately evaluate the Y2K impact on its operations of products and services
delivered by these third parties. Meridian has established procedures to ensure
that products and internal systems from new suppliers are Y2K compliant. As a
general matter, Meridian is vulnerable to any failure by its key suppliers and
contract manufacturers to remedy their own Y2K issues, which could delay
shipments of essential components and systems, thereby disrupting or halting
the Company's manufacturing operations. Further, Meridian also relies upon
governmental agencies, utility companies, telecommunication service companies
and other service providers outside of the Company's control. There is no
assurance that such suppliers, governmental agencies, financial institutions,
or other third parties will not suffer business disruptions caused by a Y2K
issue, and there is little practical opportunity for Meridian to test or
require Y2K compliance from many of those large agencies, companies or
providers. Such failures could have a material adverse effect on the Company's
business, financial condition and results of operations. During 1999, Meridian
plans to continue development of a contingency plan designed to address
problems which might arise from the failure of its suppliers or contract
manufacturers to timely and adequately address their Y2K issues.

  To date, the Company has not incurred any costs related to assessment and
remediation of Y2K readiness. A formal budget has not been established, and the
cost to Meridian of achieving Y2K readiness is evolving; however, it is not
currently expected to have a material effect on the Company's business,
financial condition, or results of operations. During 1998, Meridian completed
the installation of upgraded computer software for the Company's financial,
accounting, inventory control, order processing and other management
information systems which the vendors maintain are Y2K ready.

                                  RISK FACTORS

  The following risk factors should be considered carefully in addition to the
other information presented in this report. This report contains forward-
looking statements within the meaning of Section 27A of the Securities Act of
1933, as amended, and Section 21G of the Securities Exchange Act of 1934, as
amended, that involve risks and uncertainties. The Company's actual results may
differ significantly from the results discussed in the forward-looking
statements. Factors that might cause such differences include, but are not
limited to, the following risk factors.

  Operating Losses; Fluctuations in Quarterly Operating Results. The Company
(then known as Parallan Computer, Inc.) fundamentally changed its business in
December 1994 with the purchase of Meridian Data, Inc. During 1994, the Company
exited its prior business and product line, which had generated substantial
losses. In the first half of 1995, the Company incurred an operating loss,
excluding certain non-recurring revenue. From that point the Company operated
profitably until the first quarter of 1997, when it again began incurring net
losses. The Company has failed to meet its expectations of future revenues in
the past and may not meet future expectations. As a result of these and other
factors, the Company believes that its revenues and operating results are
difficult to predict and are subject to fluctuations from period to period.
There can be no assurance that the Company will return to profitability, or
that if profitability is achieved, will be able to sustain profitability. In
order to address its disappointing systems revenue growth, Meridian increased
its sales and promotional expenditures in 1996 and, at the end of January 1997,
significantly reduced system prices in response to competitive pressures. Unit
shipments did not increase and there can be no assurance that prices for the
Company's products will not decrease further due to competitive pricing
pressures. Accordingly, the Company may not meet its total revenue goals and
the Company's business, financial condition and results of operations would be
materially adversely affected. As a result of expenses related to the
engineering and marketing campaign of Meridian's Snap! Server, the Company
anticipates that it will operate at a substantial net operating loss through
the end of 1999.

  The Company generally ships its software and systems within a short period
after receipt of an order, therefore the Company typically does not have a
material backlog of unfilled orders. Accordingly, total revenues in any quarter
are substantially dependent on orders booked in that quarter. This may result
in quarterly fluctuations in revenue. The Company's expense levels are based,
in part, on its expectations as to future sales. As a result, if sales levels
are below expectations, net income may be disproportionately affected. The
Company's quarterly operating results may also vary significantly depending on
other factors, including the introduction of new products by the Company's
competitors; market acceptance of the Company's new products; mix of software
and systems sales; adoption of new technologies and standards; price and other
forms of competition; the long and complex sales cycle for site licenses; the
timing of site license revenue; the cost, quality and availability of third
party components used in the Company's systems; changes in the Company's
distribution arrangements; and the inability of the Company to accurately
monitor end user demand for its products due to the sale of products through
distributors and VARs.

  In 1998, identifiable sales to federal governmental agencies accounted for
approximately 8% of the Company's product sales, and the Company anticipates
that such sales will continue to account for a significant percentage of the
Company's revenues for the foreseeable future. In the event that there is any
reduction or deferral in spending by such governmental agencies, the Company's
quarterly and annual results would be adversely affected. Similarly, if such
government agencies reduced their purchases of Meridian products in favor of
those of its competitors, the Company's quarterly and annual results would be
adversely affected. The Company's operating results will also be affected by
the economic condition of the personal computer industry, which has from time
to time experienced cyclical, depressed business conditions, often in
connection with or in anticipation of a decline in general economic conditions.
Due to all of the foregoing factors, the Company's total revenues or operating
results may in one or more future quarters be below the expectations of stock
market analysts and investors. In such event, the price of the Company's Common
Stock would likely decline, perhaps substantially. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations."


                                   Annex 2-10
<PAGE>

  Product Concentration. The Company's future financial performance continues
to be contingent primarily on the success of, and growth in demand for NAS
products. The market for NAS appliances is new and undeveloped. There can be no
assurance that the Company's products will be widely accepted in this emerging
market. If demand for the Snap! Server, or other NAS devices, fails to develop,
or develops more slowly than the Company currently anticipates, the Company's
business, financial condition and results of operations would be materially
adversely affected. In addition, while there is a substantial installed base of
CD-ROM/DVD drives in the United States, growth in the CD-ROM/DVD networking
market is primarily in entry-level systems with low price points. There can be
no assurance that the Company's products will be widely accepted in this
market. If demand for the Company's CD-ROM/DVD networking products continues to
decrease, and demand for NAS products not develop, the Company's business,
financial condition and results of operations would be materially adversely
affected.

  Snap Server. The Company is actively developing additional products for its
Snap! Server family of products. This entails further expansion into non-CD-
ROM/DVD networking markets, in which the Company has minimal experience. Such
entry entails substantially higher risks to the Company in the form of new and
well established competition, and competitive dynamics different than those
experienced in the CD-ROM/DVD networking market. In attempting to successfully
enter the NAS market and other new markets, the Company will have to commit to
significant levels of engineering, sales and marketing expenditures. With
respect to NAS, Meridian must also successfully educate the market concerning
the practicality of changing from conventional means of adding storage capacity
to PC networks to installing its Snap! Server, or related products. There can
be no assurance that the Company will be successful in marketing its Snap!
Server or other new products, that the Company will not experience difficulties
that could delay or prevent the successful development, introduction and
marketing of future Snap! Server products or other new products, or that its
Snap! Server or other new products will adequately meet the requirements of the
marketplace and achieve market acceptance. If the Company is unable, for
technological or other reasons, to develop and introduce current and future
Snap! Server products or other new products in a timely manner in response to
changing market conditions or customer requirements, the Company's business,
financial condition and results of operations will all be materially adversely
affected. The Company's potential new products likely will be subject to
significant technical risk due to their complexity and the difficulty in
gauging the engineering effort required to produce such products. There can be
no assurance that future Snap! Server products and other potential new products
will be introduced on a timely basis or at all. In addition, there can be no
assurance that the Company will be able to continue to offer the functionality
and ease-of-use that it believes future Snap! Server products require for a
successful introduction. If the new products are delayed, do not offer the
functionality and ease-of-use envisioned, or do not achieve market acceptance,
the Company's business, financial condition and operating results will be
materially adversely affected. As a result of uncertainty with respect to Snap!
Server revenues and anticipated expenses required to successfully develop and
market this product, the Company anticipates that it may operate at a
substantial net operating loss through the end of 1999.

  Dependence on New Distribution Channels. The Company anticipates that VARs,
catalogs, and business-to-business retailers will play a significant role in
its Snap! Server sales strategy. In addition, as the market for the Company's
CD-ROM/DVD products transition from enterprise-servers to workgroup-servers,
the Company anticipates that catalogs and business-to-business retailers will
account for an increasingly greater proportion of the Company's revenues. Early
in 1998, some of the Company's existing CD-ROM/DVD workgroup-server products
began utilizing the same new distribution channels as the Company's Snap!
Server, in addition to the Company's traditional channels, distributors, VARs
and direct sales/telemarketing. The Company must implement marketing strategies
designed to indirectly generate end-user demand thru such new distribution
channels. There can be no assurance that the Company will be able to
effectively design and implement such strategies or that such strategies will
be successful in generating such end-user demand. The Company's agreements or
purchase orders with its catalog and business-to-business retailers typically
allow for extended payment terms and substantial rights of return. While the
Company will provide for a reserve for future returns, there can be no
assurance that the reserve will adequately cover actual product returns.

                                   Annex 2-11
<PAGE>

Excessive or unanticipated returns could materially adversely affect the
Company's business, financial condition and results of operations. The
Company's business, financial condition and results of operations could also be
materially adversely affected by changes in catalog or business-to-business
retailers' inventory strategies, which could occur rapidly, and may be
unrelated to end user demand. A failure of the Company's new distribution
channels to successfully market the Company's products would have a material
adverse effect on the Company's business, financial condition and results of
operations. As a result of the extended payment terms required by these
customers, the Company's liquidity may be adversely impacted by the timing of
payments required by its vendors preceding the receipt of payments from retail
customers.

  Competition. Initially, the Company's Snap! Server will compete with
alternative methods of adding storage to PC LAN networks such as adding new PC
servers from companies such as Dell, Compaq, Hewlett Packard and International
Business Machines Corporation ("IBM"), adding additional disk drives from
manufacturers such as Seagate and Maxtor to existing servers, and potential new
competition from semiconductor manufacturers, such as Intel Corporation. These
companies in particular and others similar to them, and the Company's
competitors in general, include large domestic and international companies,
many of which have significantly greater financial, technical, manufacturing,
marketing, sales and distribution resources than the Company. There can be no
assurance that the Company's current or potential competitors will not develop
products comparable or superior to the Snap! Server or adapt more quickly than
the Company to new or emerging technologies, evolving industry trends or
changing customer requirements. There can be no assurance that the Company will
have the financial resources, technical expertise, or marketing, sales,
distribution and customer service and technical support capabilities to compete
successfully.

  The markets for the Company's CD-ROM/DVD products are extremely competitive.
The Company expects that competition will increase if more companies enter the
market and as existing competitors continue to change and expand their product
offerings. Pricing is very aggressive in the Company's industry, and the
Company expects pricing pressures to continue to intensify. The Company's
current competitors in the CD-ROM/DVD networking market include other suppliers
of CD-ROM/DVD networking software and hardware such as Procom Technology, Inc.,
and Hewlett Packard, Inc. The Company also competes indirectly with suppliers
of personal computers, such as Dell, Compaq, and IBM, and network operating
systems such as Microsoft Corporation and Novell, Inc., to the extent such
companies include CD-ROM/DVD networking utilities as part of their operating
systems. The Company's potential competitors in the hardware area include
companies in the personal computer market and certain CD-ROM/DVD manufacturers.
These companies in particular, and the Company's competitors in general,
include large domestic and international companies, many of which have
significantly greater financial, technical, manufacturing, marketing, sales and
distribution resources than the Company. There can be no assurance that the
Company's current or potential competitors will not develop products comparable
or superior to those developed by the Company or adapt more quickly than the
Company to new or emerging technologies, evolving industry trends or changing
customer requirements. There can be no assurance that the Company will have the
financial resources, technical expertise, or marketing, sales, distribution and
customer service and technical support capabilities to compete successfully.

  The Company believes that its ability to compete successfully in the CD-
ROM/DVD networking and NAS markets will depend upon a number of factors both
within and outside of its control, including price, quality, product
performance and features; timing of new product introductions by the Company,
its customers and competitors; customer service and technical support; and the
ability of the Company to respond more quickly than current or potential
competitors to new or emerging technologies, evolving industry trends and
changes in customer requirements and to devote greater resources than current
or potential competitors to the development, promotion and sale of products.
The Company believes that it competes favorably with respect to these factors.
There can be no assurance however that the Company will have the financial
resources, technical expertise, or marketing, sales, distribution and customer
service and technical support capabilities to compete successfully.

  Dependence on Third Party Distributors. The Company derives substantially all
of its product sales through distributors, VARs, and retailers. Two
distributors accounted for 41% and 23%, respectively, of the

                                   Annex 2-12
<PAGE>

Company's 1998 product sales. The loss of either of these distributors, or
certain other distributors, VARs, or retailers would have a material adverse
effect on the Company's business, financial condition and results of
operations. The Company's contractual relationships with its distributors,
VARs, and retailers can generally be canceled upon notice to the Company.
Certain of the Company's distributors, VARs, and retailers also act as
distributors for competitors of the Company and could devote greater effort and
resources to marketing competitive products. In addition, effective
distributors, VARs, and retailers must devote significant technical, marketing
and sales resources to an often lengthy sales cycle. There can be no assurance
that the Company's current distributors, VARs, and retailers will continue to
market the Company's products effectively or that economic or industry
conditions will not adversely affect such distributors, VARs, and retailers.
Because the Company sells a significant portion of its products through
distributors, VARs, and retailers it is difficult for the Company to monitor
end user demand for its products on a current basis. Initial stocking orders
from distributors or retailers may not be indicative of long-term end user
demand. The Company's distributors and retailers typically are allowed by
contract to return products, subject to certain limitations, without charge or
penalty. While the Company provides for a reserve for future returns, there can
be no assurance that the reserve will adequately cover actual product returns.
Excessive or unanticipated returns could materially adversely affect the
Company's business, financial condition and results of operations. The
Company's business, financial condition and results of operations could also be
materially adversely affected by changes in distributors' or retailers
inventory strategies, which could occur rapidly, and may be unrelated to end
user demand. There can be no assurance that the Company's distributors, VARs,
and retailers will continue to market the Company's existing products. A
failure of the Company's distributors, VARs, and retailers to successfully
market the Company's products would have a material adverse effect on the
Company's business, financial condition and results of operations.

  The Company began shipping its new Snap! Server in the second quarter of
1998. The Snap! Server requires different marketing, sales and distribution
strategies than those for the Company's current CD-ROM/DVD products. As such,
it entails significant new risks to Meridian. There can be no assurance that
the Company's distributors, VARs, and retailers will choose or be able to
effectively market this new product or that the Company will be successful in
developing alternate channels of distribution. Initial stocking orders from
distributors or retailers may not be indicative of long-term end user demand.
The Company's contracts with distributors and purchase orders from retailers
typically allow distributors and retailers of the Snap! Server and other new
products to return products, subject to certain limitations, without charge or
penalty. The Company provides for a reserve for returns based on its
contractual obligations. A failure of the Company's distributors, VARs, and
retailers to successfully market this product, or the failure to establish
other means of marketing, sales, and distribution, would have a material
adverse effect on the Company's business, financial condition and results of
operations.

  Dependence on Third Party Suppliers. The Company is dependent on a small
number of suppliers for certain key components used in its products, including
CD-ROM and DVD drives, microprocessors, integrated circuits and power modules.
The Company purchases these components pursuant to periodic purchase orders,
does not carry significant inventories of these components, and has no long-
term supply arrangements. In addition, certain subassemblies used in the
Company's products are manufactured by a single third party vendor. The loss of
a key supplier or a disruption to the business of a key supplier could have a
material adverse effect upon the Company's business, financial condition and
results of operations. Although the Company believes that alternative sources
of components or subassemblies could be arranged, the process of qualifying new
suppliers could be lengthy and could require substantial modification of the
Company's products to ensure compatibility. There can be no assurance that any
additional source would be available to the Company at all or on a timely basis
or at a cost acceptable to the Company. Any disruption or reduction or
termination in the future supply of any key components currently obtained from
limited sources could have a material adverse effect on the Company's business,
financial condition and results of operations. In the past, there has been
unexpected significant growth in the demand for CD-ROM/DVD drives, which has
caused temporary supply disruptions. These components are only available from a
limited number of manufacturers, most of which are Japanese manufacturers. The
Company has experienced in the past, and may experience in

                                   Annex 2-13
<PAGE>

the future, an adverse impact on the cost in dollars of certain components
purchased from Japanese manufacturers due to fluctuations in the exchange rate
for the yen. Moreover, the Company has been required to make spot market
purchases for certain components at premium prices. In the third quarter of
1995, the Company experienced temporary delays in obtaining the drives required
for its products. If such delays reoccur or the Company is required to purchase
components at a higher cost due to fluctuating currency exchange rates, spot
market shortages or other factors, the Company may be unable to ship products
on the schedule anticipated or may sustain higher product costs with a
resulting adverse effect on the Company's business, financial condition and
results of operations.

  The Company anticipates that the manufacturing of its new Snap! Server,
including final assembly and testing, will be contracted out to third party
vendors, some of whom may be located in Asia. Initially, Meridian will be
dependent on a few third party contractors. Like its CD-ROM/DVD counterparts,
the Snap! Server will be dependent on a small number of suppliers for certain
key components and parts, including microprocessors, integrated circuits and
power modules. In addition, certain subassemblies used will be manufactured by
a single third party vendor. Financial, market or other developments adversely
affecting the Company's key component suppliers, or the loss of a key
subassembly manufacturer, could have an adverse effect on their ability to
supply the Company with components or assemblies and, consequently, could have
a material adverse effect upon the Company's business, financial condition and
results of operations. The process of qualifying new suppliers or subassembly
manufacturers would be lengthy, and there can be no assurance that any
additional source would be available to the Company on a timely basis or at a
cost acceptable to the Company. Any disruption or reduction in the future
supply of any key components currently obtained from limited sources could have
a material adverse effect on the Company's business, financial condition and
results of operations

  Rapid Technological Change; Potential for Product Defects; and Obsolesce. The
market for the Company's products is characterized by rapid technological
advances, evolving industry standards in computer hardware and software
technology, changes in customer requirements and frequent new product
introductions and enhancements. The Company's future success will depend on its
ability to continue to enhance its current product line and to continue to
develop and introduce new products that keep pace with competitive product
introductions and technological developments, satisfy diverse and evolving
customer requirements and otherwise achieve market acceptance. There can be no
assurance that the Company will be successful in continuing to develop and
market on a timely and cost-effective basis new products or product
enhancements that respond to technological advances by others, or that these
products will achieve market acceptance. In addition, companies in the industry
have in the past experienced delays in the development, introduction and
marketing of new and enhanced products, and there can be no assurance that the
Company will not experience delays in the future. Any failure by the Company to
anticipate or respond adequately to changes in technology and customer
preferences, or any significant delays in product development or introduction,
would have a material adverse effect on the Company's business, financial
condition and results of operations.

  Due to their complexity and sophistication, the Company's products from time
to time may contain hardware or software defects or "bugs" which can be
difficult to correct. Furthermore, as the Company continues to develop and
enhance its products, there can be no assurance that the Company will be able
to identify and correct defects in a manner that will permit the timely
introduction of such products. Moreover, despite extensive testing, the Company
has from time to time discovered defects only after its products have been
commercially released. There can be no assurance that such defects will not
cause delays in product introductions and shipments or loss of or delay in
market acceptance, result in increased costs, require design modifications,
impair customer satisfaction, or result in customer returns. Any such event
could materially adversely affect the Company's business, financial condition
and results of operations.

  Over the past two years, CD-ROM/DVD drive technology has advanced
significantly. Additionally, the pace of new drive introductions has increased.
As a result, the Company may find itself holding an inventory of obsolete
drives. Further, the Company's contracts with its distributors and retailers
allow for product return, or price protection credits, based on their inventory
levels of current products and, under certain circumstances,

                                   Annex 2-14
<PAGE>

obsolete products. Meridian estimates and accrues its required allowance for
such occurrences, but there can be no assurance that actual inventory
writedowns, product returns, or price protection credits will not exceed the
Company's estimate. Such an event could materially adversely affect the
Company's business, financial condition and results of operations.

  Expansion of International Operations. There can be no assurance that the
Company will be able to successfully localize, market, sell and deliver its
products internationally. The inability of the Company to successfully expand
its international operations in a timely and cost effective manner could
materially adversely affect the Company's business, financial condition and
results of operations. International product sales were approximately 11% of
total product sales in 1998. The Company's business, financial condition and
results of operations could be materially adversely affected by risks inherent
in conducting business internationally, such as changes in currency exchange
rates, longer payment cycles, difficulties in staffing and managing
international operations, problems in collecting accounts receivable, slower
acceptance of technology advances compared with the United States, lack of
published CD-ROM/DVD content, seasonal reductions in business activity during
the summer months in Europe and certain other parts of the world, and tariffs,
duties and other trade barriers. For a discussion of the effect of fluctuations
in the exchange rate of the Japanese yen on the cost of certain components used
in the Company's products, see "Risk Factors--Dependence on Third Party
Suppliers."

  Dependence on Key Personnel; Management of Growth. Due to the specialized
nature of the Company's business, the Company's future success is highly
dependent upon the continued services of its key engineering personnel and
executive officers and upon its ability to attract and retain qualified
engineering, sales and marketing, management and manufacturing personnel for
its operations. Competition for such personnel is intense. There can be no
assurance that the Company will be successful in attracting or retaining such
personnel. The loss of any key personnel or the Company's inability to attract
and retain qualified employees could have a material adverse effect on the
Company's business, financial condition and results of operations. None of the
Company's key employees has an employment agreement with the Company, and the
Company does not maintain key man insurance policies on the lives of its key
employees. Although the Company's senior executives have lengthy experience in
the computer industry, they have no experience with the NAS market that the
Company has entered. To manage its growth, the Company must continue to
implement and improve its operational, financial and management information
systems and expand, train and manage its workforce. Meridian believes that
success in its industry requires substantial capital in order to maintain the
flexibility to take advantage of opportunities as they may arise. The Company
may, from time to time, as market and business conditions warrant, invest in or
acquire complementary businesses, products or technologies. Such investment or
acquisitions may be funded by internally generated cash, marketable securities,
debt, or the sale of additional equity. The sale of additional equity would
result in dilution in the equity ownership of Meridian's stockholders. The
Company's failure to manage growth effectively could have a material adverse
effect on the Company's business, financial condition and results of
operations.

  Employees. As of December 31, 1998, the Company employed 83 individuals, of
whom 13 were employed in manufacturing, 27 in research and development, 23 in
sales and marketing, 7 in customer support, 1 in product management, and 12 in
administration and finance. Competition in the recruiting of personnel in the
computer and networking industry is intense. The Company believes that its
future success will depend, in part, upon the continued services of its key
engineering personnel and executive officers and upon its ability to attract
and retain qualified engineering, sales and marketing, management and
manufacturing personnel for its operations. None of the Company's employees are
represented by a labor union or are subject to a collective bargaining
agreement. The Company believes that relations with its employees are good.

  To manage its growth, the Company must continue to implement and improve its
operational, financial and management information systems and expand, train and
manage its workforce. The Company's failure to manage growth effectively could
have a material adverse effect on the Company's business, financial condition
and results of operations. See "Risk Factors--Dependence on Key Personnel;
Management of Growth."

                                   Annex 2-15
<PAGE>

  Dependence on Proprietary Rights. The Company's success depends in part upon
protecting its proprietary technology. The Company relies on a combination of
intellectual property laws, nondisclosure agreements and other protective
measures to protect its proprietary information. There can be no assurance,
however, that the steps taken by the Company will be adequate to deter
misappropriation or independent third party development of its technology or
that its intellectual property rights can be successfully defended if
challenged. Litigation may be necessary to protect the Company's proprietary
rights. Any such litigation may be time-consuming and costly. In addition, the
laws of certain foreign countries do not protect the Company's intellectual
property rights to the same extent as the laws of the United States. Given the
rapid development of technology, there can be no assurance that certain aspects
of the Company's products do not or will not infringe upon the existing or
future proprietary rights of others or that, if licenses or rights are required
to avoid infringement, such licenses or rights could be obtained or obtained on
terms that are acceptable to the Company. The Company is not currently aware of
any infringement of its proprietary rights, nor is it aware of any claims that
its products infringe the rights of others.

  Possible Volatility of Stock Price. The Company believes that factors such as
announcements of developments related to the Company's business, announcements
by competitors, quarterly fluctuations in the Company's financial results,
conditions in the CD-ROM/DVD networking and NAS industries, changes in the
general economy and other factors could cause the price of the Company's Common
Stock to fluctuate, perhaps substantially. In addition, in recent years the
stock market in general, and the market for shares of small capitalization
technology stocks in particular, have experienced extreme price fluctuations,
which have often been unrelated to the operating performance of affected
companies. Such fluctuations could have a material adverse effect on the market
price of the Company's Common Stock.

  Anti-Takeover Effect of Stockholder Rights Plan and Certain Charter and Bylaw
Provisions. In July 1997, the Company's Board of Directors adopted a Preferred
Shares Rights Plan (the "Rights Plan"). The Rights Plan provides for a dividend
distribution of one Preferred Shares Purchase Right (a "Right") on each
outstanding share of the Company's Common Stock. The Rights will become
exercisable following the tenth day after a person or group announces
acquisition of 15% or more of the Company's Common Stock, or announces
commencement of a tender offer, the consummation of which would result in
ownership by the person or group of 15% or more of the Company's Common Stock.
The Company will be entitled to redeem the Rights at $0.01 per Right at any
time on or before the tenth day following acquisition by a person or group of
15% of more of the Company's Common Stock.

  The Rights Plan and certain provisions of the Company's Certificate of
Incorporation and Bylaws may have the effect of making it more difficult for a
third party to acquire, or of discouraging a third party from attempting to
acquire, control of the Company. The Company's Certificate of Incorporation
allows the Company to issue Preferred Stock without any vote or further action
by the stockholders, and certain provisions of the Company's Certificate of
Incorporation and Bylaws specify procedures for director nominations by
stockholders and submission of other proposals for consideration at stockholder
meetings, and eliminate cumulative voting in the election of directors. Certain
provisions of Delaware law could also delay or make more difficult a merger,
tender offer or proxy contest involving the Company, including Section 203,
which prohibits a Delaware corporation from engaging in any business
combination with any interested stockholder for a period of three years unless
certain conditions are met. The Rights Plan, the possible issuance of Preferred
Stock, the procedures required for director nominations and stockholder
proposals and Delaware law could have the effect of delaying, deferring or
preventing a change in control of the Company, including without limitation,
discouraging a proxy contest or making more difficult the acquisition of a
substantial block of the Company's Common Stock. These provisions could also
limit the price that investors might be willing to pay in the future for shares
of the Company's Common Stock.

  Potential Seismic Disturbances. The Company's research and development
activities, its corporate headquarters, other critical business operations and
certain of its suppliers are located near major earthquake faults. The ultimate
impact on the Company, its significant suppliers and the general infrastructure
is unknown, but operating results could be materially affected in the event of
a major earthquake. The Company is predominantly uninsured for losses and
interruptions caused by earthquakes.

                          PART II.--OTHER INFORMATION

                     INFORMATION NOT REQUIRED IN PROSPECTUS

Item 20. Indemnification of Directors and Officers.

  Quantum's bylaws provide that Quantum will indemnify its directors and
executive officers and may indemnify its other officers, employees and other
agents to the fullest extent permitted by Delaware law. Quantum is also
empowered under its bylaws to enter into indemnification contracts with its
directors and officers and to purchase insurance on behalf of any person it is
required or permitted to indemnify. Pursuant to this provision, Quantum expects
to enter into indemnification agreements with each of its directors and
executive officers.

  Quantum has obtained officer and director liability insurance with respect to
liabilities arising out of certain matters, including matters arising under the
Securities Act. In addition, Quantum's certificate of incorporation provides
that, to the fullest extent permitted by Delaware law, Quantum's directors will
not be liable for monetary damages for breach of the directors' fiduciary duty
of care to Quantum and its stockholders. This provision in the certificate of
incorporation does not eliminate the duty of care, and in appropriate
circumstances, equitable remedies such as an injunction or other forms of non-
monetary relief would remain available under Delaware law. Under current
Delaware law, a director's liability to Quantum or its stockholders may not be
limited with respect to any breach of the director's duty of loyalty to Quantum
or its stockholders, for acts or omissions not in good faith or involving
intentional misconduct, for knowing violations of law, for any transaction from
which the director derived an improper personal benefit, for improper
transactions between the director and Quantum and for improper distributions to
stockholders and loans to directors and officers. This provision also does not
affect a director's responsibilities under any other laws such as the federal
securities laws or state or federal environmental laws.

  There is pending litigation in which directors and officers of Quantum have
been named as to which indemnification is being sought and such claims are
described in Quantum's annual report on Form 10-K for the year ended March 31,
1999, incorporated herein by reference.

  The Registrant has obtained directors' and officers' liability insurance that
covers certain liabilities, including liabilities to the Registrant and its
stockholders.

  Pursuant to the merger agreement, all rights to indemnification existing in
favor of the persons serving as directors or officers of Meridian as of the
date of the merger agreement for acts and omissions occurring prior to the
effective time, as provided in the Meridian bylaws and as provided in any
indemnification agreements between Meridian and said officers and directors
shall survive the merger and shall be observed by Quantum and the surviving
corporation for a period of not less than six years from the effective time.
The merger agreement also provides that from the effective time until the third
anniversary of the date on which the merger becomes effective, the surviving
corporation shall maintain in effect, for the benefit of the persons serving as
directors and officers of Meridian as of the date of the merger agreement with
respect to acts or omissions occurring prior to the effective time, the lesser
of (i) the existing policy of directors' and officers' liability insurance
maintained by Meridian as of the date of the merger agreement (the "existing
policy") and (ii) the amount of coverage purchased by 150% of the amount of the
last annual premium paid by Meridian prior to the date of the merger agreement
for the existing policy; provided, however, that the surviving corporation may
substitute for the existing policy a policy or policies of comparable coverage.

  (c) Item 4(B) Reports

  See Appendix B to the joint proxy statement/prospectus.

Item 22. Undertakings.

  (1) The Registrant hereby undertakes to respond to requests for information
that is incorporated by reference into the joint proxy statement/prospectus
pursuant to Items 4, 10(b), 11 or 13 of Form S-4, within one business day of
receipt of such request, and to send the incorporated documents by first class
mail or other equally prompt means. This includes information contained in
documents filed subsequent to the effective date of the registration statement
through the date of responding to the request.

  (2) The Registrant hereby undertakes to supply by means of a post-effective
amendment all information concerning a transaction, and the company being
acquired involved therein, that was not the subject of and included in the
registration statement when it became effective.

  (3) The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act, each filing of the
Registrant's annual report pursuant to section 13(a) or section 15(d) of the
Exchange Act (and, where applicable, each filing of an employee benefit plan's
annual report pursuant to section 15(d) of the Exchange Act) that is
incorporated by reference in the registration statement shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

  (4) Insofar as indemnification for liabilities arising under the Securities
Act may be permitted to directors, officers and controlling persons of the
Registrant pursuant to the amended and restated certificate of incorporation
and the bylaws of the Registrant and the Delaware General Corporation Law, the
Registrant has been advised that in the opinion of the Securities and Exchange
Commission such indemnification is against public policy as expressed in the
Securities Act and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
Registrant of expenses incurred or paid by a director, officer or controlling
person of the Registrant in a successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the Registrant will, unless in
the opinion of its counsel the question has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question of
whether such indemnification by it is against public policy as expressed in the
Act and will be governed by the final adjudication of such issue.

  (5) (A) The undersigned Registrant hereby undertakes as follows: that prior
to any public reoffering of the securities registered hereunder through use of
a prospectus which is a part of this registration statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c), the
issuer undertakes that such reoffering prospectus will contain the information
called for by the applicable registration form with respect to reofferings by
persons who may be deemed underwriters, in addition to the information called
for by the other items of the applicable form.

  (B) The Registrant undertakes that every prospectus: (i) that is filed
pursuant to paragraph (A) immediately preceding, or (ii) that purports to meet
the requirements of Section 10(a)(3) of the Securities Act and is used in
connection with an offering of securities subject to Rule 415, will be filed as
a part of an amendment to the registration statement and will not be used until
such amendment is effective, and that, for purposes of determining any
liability under the Securities Act, each such post-effective amendment shall be
deemed to be a new registration statement relating to the securities offered
therein, and the offering of such securities at that time shall be deemed to be
the initial bona fide offering thereof.

August 9, 1999

Quantum Corporation
500 McCarthy Blvd.
Milpitas, California 95035

Ladies and Gentlemen:

  We have acted as counsel for Quantum Corporation, a Delaware corporation (the
"Company" or "Quantum"), in connection with the merger (the "Merger") and other
transactions contemplated by the certain Agreement and Plan of Merger and
Reorganization, dated as of May 10, 1999, by and among Quantum, Defiant
Acquisition Sub, Inc., a Delaware corporation and a wholly-owned subsidiary of
Quantum ("Merger Sub"), and Meridian Data, Inc., a Delaware corporation
("Meridian"), as amended by the First Amendment dated as of June 28, 1999. This
opinion is being furnished in connection with a Registration Statement on
Form S-4 (the "Registration Statement") to be filed by the Company with the
Securities and Exchange Commission covering the offer and sale of up to
5,181,674 shares (the "DSS Shares") of DLT & Storage Systems Group Common
Stock, par value $0.01 per share, and up to 2,590,837 shares (the "HDD Shares")
of Hard Disk Drive Group Common Stock, par value $0.01 per share, of the
Company, to be issued in connection with the merger of Merger Sub with and into
Meridian.

  In rendering this opinion, we have examined the following documents: (i) the
Company's Certificate of Incorporation and Bylaws, as amended and restated
since the inception of the Company; (ii) the Minutes of a Meeting of the Board
of Directors dated April 21, 1999; (iii) the Registration Statement; and (iv)
such other documents, legal opinions and precedents, corporate and other
records of the Company, and certificates of public officials and officers of
the Company that we have deemed necessary or appropriate to provide a basis for
the below opinion.

  We are of the opinion that the DSS Shares and HDD Shares, which are being
offered and sold by the Company pursuant to the Registration Statement, when
sold in the manner and for the consideration contemplated by the Registration
Statement, will be validly issued, fully paid and non-assessable.

  We consent to the filing of this opinion as an Exhibit to the Registration
Statement and to the reference to our firm under the heading "Legal Matters."

                                          Sincerely,

August 9, 1999

Quantum Corporation
Attn: General Counsel
500 McCarthy Blvd.
Milpitas, CA 95035

Ladies and Gentlemen:

  This opinion is being delivered to you in connection with the Form S-4
Registration Statement (the "Registration Statement") filed pursuant to the
Agreement and Plan of Merger and Reorganization dated as of May 10, 1999 (the
"Reorganization Agreement") by and among Quantum Corporation, a Delaware
corporation ("Parent"), Defiant Acquisition Sub, Inc., a Delaware corporation
and wholly owned subsidiary of Parent ("Merger Sub"), Meridian Data, Inc., a
Delaware corporation (the "Delaware Company") and Meridian Data, Inc., a
California corporation to the extent such corporation is in existence (the
"California Company"), as amended by the First Amendment dated as of June 28,
1999. The Delaware Company and the California Company are referred to
collectively herein as the "Company".

  Except as otherwise provided, capitalized terms used but not defined herein
shall have the meanings set forth in the Reorganization Agreement. All section
references, unless otherwise indicated, are to the Internal Revenue Code of
1986, as amended (the "Code").

  We have acted as counsel to Parent and Merger Sub in connection with the
Merger. As such, and for the purpose of rendering this opinion, we have
examined, and are relying upon (without any independent investigation or review
thereof) the truth and accuracy, at all relevant times, of the statements,
covenants, representations and warranties contained in the following documents
(including all exhibits and schedules attached thereto):

    (a) the Reorganization Agreement;

    (b) the Registration Statement;

    (c) those certain tax representation letters delivered to us by Parent,
  Merger Sub and the Company containing certain representations of Parent,
  Merger Sub and the Company (the "Tax Representation Letters"); and

    (d) such other instruments and documents related to the formation,
  organization and operation of Parent, Merger Sub and the Company and
  related to the consummation of the Merger and the other transactions
  contemplated by the Reorganization Agreement as we have deemed necessary or
  appropriate.

  In connection with rendering this opinion, we have assumed (without any
independent investigation or review thereof) that:

    (a) Original documents submitted to us (including signatures thereto) are
  authentic, documents submitted to us as copies conform to the original
  documents, and that all such documents have been (or

                                       1
<PAGE>

  will be by the Effective Time) duly and validly executed and delivered
  where due execution and delivery are a prerequisite to the effectiveness
  thereof;

    (b) All representations, warranties and statements made or agreed to by
  Parent, Merger Sub and the Company, their managements, employees, officers,
  directors and stockholders in connection with the Merger, including, but
  not limited to, those set forth in the Reorganization Agreement (including
  the exhibits thereto) and the Tax Representation Letters are true and
  accurate at all relevant times;

    (c) All covenants contained in the Reorganization Agreement (including
  exhibits thereto) and the Tax Representation Letters are performed without
  waiver or breach of any material provision thereof;

    (d) The Merger will be reported by Parent and the Company on their
  respective federal income tax returns in a manner consistent with the
  opinion set forth below;

    (e) Any representation or statement made "to the best of knowledge" or
  similarly qualified is correct without such qualification; and

    (f) The opinion dated August 9, 1999 rendered by Brobeck, Phleger &
  Harrison LLP to the Company pursuant to Section 7.5(a) of the
  Reorganization Agreement has been delivered and has not been withdrawn.

  Based on our examination of the foregoing items and subject to the
assumptions, exceptions, limitations and qualifications set forth herein, we
are of the opinion that the statements regarding the United States federal
income tax consequences set forth in the Registration Statement under the
heading "Material Federal Income Tax Consequences," insofar as they constitute
statements of law or legal conclusions, are correct in all material respects.

  This opinion does not address the various state, local or foreign tax
consequences that may result from the Merger or the other transactions
contemplated by the Reorganization Agreement. In addition, no opinion is
expressed as to any federal income tax consequence of the Merger or the other
transactions contemplated by the Reorganization Agreement except as
specifically set forth herein, and this opinion may not be relied upon except
with respect to the consequences specifically discussed herein. No opinion is
expressed as to the federal income tax treatment that may be relevant to a
particular investor in light of personal circumstances or to certain types of
investors subject to special treatment under the federal income tax laws (for
example, life insurance companies, dealers in securities, taxpayers subject to
the alternative minimum tax, banks, tax-exempt organizations, non-United States
persons, and stockholders who acquired their shares of Company capital stock
pursuant to the exercise of options or otherwise as compensation or who hold
their Company capital stock as part of a straddle or risk reduction
transaction).

  No opinion is expressed as to any transaction other than the Merger as
described in the Reorganization Agreement, or as to any transaction whatsoever,
including the Merger, if all of the transactions described in the
Reorganization Agreement are not consummated in accordance with the terms of
the Reorganization Agreement and without waiver of any material provision
thereof. To the extent that any of the representations, warranties, statements
and assumptions material to our opinion and upon which we have relied are not
accurate and complete in all material respects at all relevant times, our
opinion would be adversely affected and should not be relied upon.

  This opinion only represents our best judgment as to the federal income tax
consequences of the Merger and is not binding on the Internal Revenue Service
or any court of law, tribunal, administrative agency or other governmental
body. The conclusions are based on the Code, existing judicial decisions,
administrative regulations and published rulings. No assurance can be given
that future legislative, judicial or administrative changes or interpretations
would not adversely affect the accuracy of the conclusions stated herein.
Nevertheless, by rendering this opinion, we undertake no responsibility to
advise you of any new developments in the application or interpretation of the
federal income tax laws.

  This opinion is being delivered solely in connection with the filing of the
Registration Statement. It is intended for the benefit of Parent, Merger Sub
and the stockholders of Parent and may not be relied upon or utilized for any

person without our prior written consent.

  We consent to the reference to our firm under the caption "Material Federal
Income Tax Consequences" in the Proxy Statement included in the Registration
Statement and to the reproduction and filing of this opinion as an exhibit to

Scotts Valley, CA 95006

Ladies and Gentlemen:

  This opinion is being delivered to you in connection with (i) the Agreement
and Plan of Merger and Reorganization (the "Agreement") dated as of May 10,
1999, as amended by the First Amendment dated as of June 28, 1999, among
Quantum Corporation, a Delaware corporation ("Quantum"), Defiant Acquisition
Sub, Inc., a Delaware corporation ("Sub"), Meridian Data, Inc., a Delaware
corporation ("Meridian"), and Meridian Data, Inc., a California corporation,
and (ii) the preparation and filing with the Securities and Exchange Commission
of a Form S-4 Registration Statement relating to the Merger (the "Registration
Statement"). Pursuant to the Agreement, Sub will merge with and into Meridian
(the "Merger"), and Meridian will become a wholly owned subsidiary of Quantum.

  Except as otherwise provided, capitalized terms referred to herein have the
meanings set forth in the Agreement. All section references, unless otherwise
indicated, are to the Internal Revenue Code of 1986, as amended (the "Code").

  We have acted as legal counsel to Meridian in connection with the Merger. As
such, and for the purpose of rendering this opinion, we have examined and are
relying upon (without any independent investigation or review thereof) the
truth and accuracy, at all relevant times, of the statements, covenants,
representations and warranties contained in the following documents (including
all schedules and exhibits thereto):

    1. The Agreement;

    2. The Registration Statement;

    3. Tax representation letters (the "Tax Representation Letters")
  delivered to us by Quantum and Meridian; and

    4. Such other instruments and documents related to Quantum, Meridian and
  Sub and to the consummation of the Merger and the other transactions
  contemplated by the Agreement as we have deemed necessary or appropriate.

  In connection with rendering this opinion, we have assumed or obtained
representations (and are relying thereon, without any independent investigation
or review thereof) that:

    A. Original documents submitted to us (including signatures) are
  authentic, documents submitted to us as copies conform to the original
  documents, and there has been (or will be by the Effective Time) due
  execution and delivery of all documents where due execution and delivery
  are prerequisites to the effectiveness thereof;

    B. The Tax Representation Letters are true in all material respects;

    C. The Merger will be consummated in accordance with the Agreement
  without any waiver or breach of any material provision thereof, and the
  Merger will be effective under applicable state law; and

    D. Cooley Godward LLP has delivered an opinion substantially similar to
  this opinion to Quantum and such opinion has not been withdrawn.

  Based on our examination of the foregoing items and subject to the
assumptions, exceptions, limitations and qualifications set forth herein, we
are of the opinion that the statements regarding United States federal income
tax consequences set forth in the Registration Statement under the heading
"Material Federal Income Tax Consequences," insofar as they constitute
statements of law or legal conclusions, are correct in all material respects.
We express no opinion as to any federal, state or local, foreign or other tax
consequences, other than as set forth in the Registration Statement under the
heading "Material Federal Income Tax Consequences."

  In addition to the assumptions and representations described above, this
opinion is subject to the exceptions, limitations and qualifications set forth
below.

    (1) This opinion represents and is based upon our best judgment regarding
  the application of federal income tax laws arising under the Code, existing
  judicial decisions, administrative regulations and published rulings and
  procedures. Our opinion is not binding upon the Internal Revenue Service or
  the courts, and there is no assurance that the Internal Revenue Service
  will not successfully assert a contrary position. Furthermore, no assurance
  can be given that future legislative, judicial or administrative changes,
  on either a prospective or retroactive basis, will not adversely affect the
  accuracy of the conclusions stated herein. Nevertheless, we undertake no
  responsibility to advise you of any new developments in the application or
  interpretation of the federal income tax laws.

    (2) No opinion is expressed as to any transaction other than the Merger
  (whether or not undertaken in connection with the Merger) or as to any
  transaction whatsoever, including the Merger, if all the transactions
  described in the Agreement are not consummated in accordance with the terms
  of such Agreement and without waiver or breach of any material provision
  thereof or if all of the representations, warranties, statements and
  assumptions upon which we relied (including, without limitation, the Tax
  Representation Letters of the parties referred to above) are not true and
  accurate at all relevant times. In the event any one of the statements,
  representations, warranties or assumptions upon which we have relied to
  issue this opinion is incorrect, our opinion might be adversely affected
  and may not be relied upon.

  This opinion is rendered to you solely in connection with the filing of the
Registration Statement. We hereby consent to the filing of this opinion as an
exhibit to the Registration Statement. We also consent to the references to our
firm name wherever appearing in the Registration Statement with respect to the
discussion of the federal income tax consequences of the Merger, including any
amendments to the Registration Statement. This opinion may not be relied upon
for any other purpose, and may not be made available to any other person,
without our prior written consent.

                                          Very truly yours,
