                            STORAGE DIMENSIONS, INC.
 
Dear Stockholder:
 
     You are cordially invited to attend a Special Meeting of the Stockholders
of Storage Dimensions, Inc. ("Storage Dimensions"), which will be held at 9:00
a.m. on March 31, 1998 (the "Storage Dimensions Special Meeting"), at the
corporate offices of Storage Dimensions at 1656 McCarthy Boulevard, Milpitas, CA
95035.
 
     At the Storage Dimensions Special Meeting, you will be asked to consider
and vote upon proposals to (i) combine the business and operations of Storage
Dimensions with those of Artecon, Inc. (the "Business Combination"); (ii) amend
Storage Dimensions' Certificate of Incorporation to provide for a classified
Board of Directors; (iii) amend Storage Dimensions' Certificate of Incorporation
to provide that a director may not be removed from office without cause except,
until the third annual meeting of Storage Dimensions following the Merger, by
the affirmative vote of at least 80% of the outstanding voting stock of Storage
Dimensions and by the affirmative vote of at least 66 2/3% of the outstanding
voting stock of Storage Dimensions thereafter; (iv) increase the number of
shares authorized for issuance pursuant to Storage Dimensions' 1996 Stock Option
Plan by 2,000,000 shares; and (v) increase the number of shares authorized for
issuance pursuant to Storage Dimensions' 1996 Employee Stock Purchase Plan by
200,000 shares (the amendments referred to in clauses (ii) and (iii) above are
hereinafter collectively referred to as the "Certificate of Incorporation
Amendments" and the amendments referred to in clauses (iv) and (v) above are
hereinafter collectively referred to as the "Stock Plan Amendments"). Each of
these proposals is described more fully in the accompanying Notice of Special
Meeting of Stockholders and Joint Proxy Statement/Prospectus. In the Business
Combination, Storage Dimensions will issue an aggregate of approximately
13,120,000 shares of Storage Dimensions Common Stock to the holders of Artecon
Common Stock. Such shares would have a value of approximately $52,480,000, based
upon the closing price of Storage Dimensions Common Stock as reported on the
Nasdaq National Market on February 23, 1998. In addition, Storage Dimensions
will issue an aggregate of 2,494,159 shares of Storage Dimensions Series A
Preferred Stock (convertible into a maximum of approximately 831,000 shares of
Storage Dimensions Common Stock) to certain Artecon shareholders, which shares
will not be publicly traded. Immediately following the Business Combination, the
former holders of Artecon capital stock will hold approximately 62.5% of the
outstanding capital stock of Storage Dimensions and current holders of Storage
Dimensions Common Stock will hold approximately 37.5% of the outstanding capital
stock of Storage Dimensions.
 
     While the percentage of outstanding capital stock of Storage Dimensions to
be held by former holders of Artecon Common Stock and current holders of Storage
Dimensions Common Stock following the Business Combination is fixed, the exact
number of shares of Storage Dimensions Common Stock issuable to the former
Artecon shareholders (but not shares of Storage Dimensions Preferred Stock) is
subject to modest change based upon changes in the number of outstanding shares
of Storage Dimensions Common Stock and Artecon Common Stock prior to the
Business Combination. Based upon the number of shares of each company
outstanding on February 23, 1998, approximately 2.16 shares of Storage
Dimensions Common Stock would be issued for each share of Artecon Common Stock
in the Business Combination (the "Exchange Ratio"). While dollar fluctuations in
the market price of Storage Dimensions Common Stock will not affect the Exchange
Ratio, they would change the aggregate value of shares of Storage Dimensions
Common Stock issued in the Business Combination.
 
     In addition, in connection with the Business Combination, Storage
Dimensions will change its name to "Artecon, Inc." and the Storage Dimensions
Common Stock will be traded on the Nasdaq National Market under the symbol
"ARTE."
 
     If the requisite approvals of the stockholders of Storage Dimensions and
the shareholders of Artecon, Inc. are received and all other conditions to
closing are satisfied or waived, the Merger is anticipated to close by March 31,
1998. Storage Dimensions stockholders do not have dissenters' or appraisal
rights under Delaware law as a result of the Merger.

                            STORAGE DIMENSIONS, INC.
 
                   NOTICE OF SPECIAL MEETING OF STOCKHOLDERS
 
     NOTICE IS HEREBY GIVEN that a Special Meeting of Stockholders of Storage
Dimensions, Inc., a Delaware corporation ("Storage Dimensions"), will be held at
9:00 a.m. on March 31, 1998 (the "Storage Dimensions Special Meeting"), at the
corporate offices of Storage Dimensions at 1656 McCarthy Boulevard, Milpitas, CA
95035.
 
     The meeting is called for the purpose of considering and voting upon:
 
          Proposal 1. A proposal (the "Business Combination Proposal") to
     approve (i) the Agreement and Plan of Merger and Reorganization dated as of
     December 22, 1997 (the "Reorganization Agreement"), among Storage
     Dimensions, Storage Acquisition Corp., a newly formed, a wholly-owned
     subsidiary of Storage Dimensions ("Merger Sub"), and Artecon, Inc., a
     California corporation ("Artecon"), and the Merger of Merger Sub with and
     into Artecon, whereby Merger Sub will cease to exist and Artecon will
     become a wholly-owned subsidiary of Storage Dimensions (the "Merger") and
     (ii) proposed amendments to Storage Dimensions' Certificate of
     Incorporation to change its name to "Artecon, Inc." following the Merger
     and to designate a new class of Series A Preferred Stock.
 
          As a result of the Merger, each outstanding share of Artecon Common
     Stock (other than Dissenting Shares, as defined herein) will be converted
     into the right to receive approximately 2.16 shares of Storage Dimensions
     Common Stock (the "Exchange Ratio") and each outstanding share of Artecon
     Preferred and Preferred B Stock (collectively, the "Artecon Preferred
     Stock")(other than Dissenting Shares) will be converted into the right to
     receive one share of newly designated Storage Dimensions Series A Preferred
     Stock. The Storage Dimensions Common Stock to be issued to the holders of
     Artecon Common Stock and the Storage Dimensions Series A Preferred Stock to
     be issued to the holders of Artecon Preferred Stock in the Merger are
     collectively referred to herein as the "Merger Consideration." Following
     the Merger, the former holders of Artecon Common Stock will hold in the
     aggregate approximately 13,120,000 shares of Storage Dimensions Common
     Stock, based upon the number of shares of Storage Dimensions Common Stock
     outstanding on February 23, 1998. Such shares would have a value of
     approximately $52,480,000, based upon the closing price of Storage
     Dimensions Common Stock as reported on the Nasdaq National Market on
     February 23, 1998. In addition, Storage Dimensions will issue an aggregate
     of 2,494,159 shares of Storage Dimensions Series A Preferred Stock
     (convertible into a maximum of approximately 831,000 shares of Storage
     Dimensions Common Stock) to certain Artecon shareholders. Immediately
     following the Business Combination, the former holders of Artecon capital
     stock will hold approximately 62.5% of the outstanding capital stock of
     Storage Dimensions and current holders of Storage Dimensions Common Stock
     will hold approximately 37.5% of the outstanding capital stock of Storage
     Dimensions.
 
          While the percentage of outstanding capital stock of Storage
     Dimensions to be held by former holders of Artecon Common Stock and current
     holders of Storage Dimensions Common Stock following the Business
     Combination is fixed, the exact number of shares of Storage Dimensions
     Common Stock issuable to the former Artecon shareholders (but not shares of
     Storage Dimensions Preferred Stock) is subject to modest change based upon
     changes in the number of outstanding shares of Storage Dimensions Common
     Stock and Artecon Common Stock prior to the Business Combination. Based
     upon the number of shares of each company outstanding on February 23, 1998,
     approximately 2.16 shares of Storage Dimensions Common Stock would be
     issued for each share of Artecon Common Stock in the Business Combination
     (the "Exchange Ratio"). While dollar fluctuations in the market price of
     Storage Dimensions Common Stock will not affect the Exchange Ratio, they
     would change the aggregate value of shares of Storage Dimensions Common
     Stock issued in the Business Combination. A copy of the Reorganization
     Agreement is attached as Annex A to the Joint Proxy Statement/Prospectus. A
     copy of the proposed amendment to the Storage Dimensions Certificate of
     Incorporation (the "Certificate of Amendment") is attached as Annex B to
     this Joint Proxy Statement/Prospectus.
 
          If the requisite approval of the stockholders of Storage Dimensions
     and Artecon is received and all other conditions to the Merger are
     satisfied or waived, the Merger is anticipated to close by March 31, 1998.
 
          Proposal 2. A proposal to approve an amendment to Storage Dimensions'
     Certificate of Incorporation to provide for a classified Board of Directors
     whereby the directors will be separated into three classes with members of
     each class serving for a three year term;
<PAGE>   5
 
          Proposal 3. A proposal to approve an amendment to Storage Dimensions'
     Certificate of Incorporation to provide that a director may not be removed
     from office without cause except, until the third annual meeting of Storage
     Dimensions following the Merger, by the affirmative vote of at least 80% of
     the outstanding voting stock of Storage Dimensions and by the affirmative
     vote of at least 66 2/3% of the outstanding voting stock of Storage
     Dimensions thereafter;
 
          Proposal 4. A proposal to approve an amendment to Storage Dimensions'
     1996 Stock Option Plan to increase the number of shares that may be issued
     thereunder from 1,000,000 to 3,000,000 (the "1996 Option Plan Amendment");
 
          Proposal 5. A proposal to approve an amendment to Storage Dimensions'
     1996 Employee Stock Purchase Plan to increase the number of shares that may
     be issued thereunder from 200,000 to 400,000 (the "Purchase Plan
     Amendment"); and
 
          Such other business as may properly come before the Storage Dimensions
     Special Meeting or any adjournments or postponements thereof.
 
     Proposals 2 and 3 above are collectively referred to herein as the
"Certificate of Incorporation Amendments." Proposals 4 and 5 are collectively
referred to herein as the "Stock Plan Amendments."
 
     The effectiveness of the Certificate of Incorporation Amendments is subject
to the approval of the Business Combination Proposal. Notwithstanding any
indication to the contrary on a proxy card, a vote against the Business
Combination Proposal will constitute a vote against the Certificate of
Incorporation Amendments. In addition, Proposals 2 and 3 are mutually dependent.
That is, a vote against Proposal 2 will constitute a vote against Proposal 3,
and a vote against Proposal 3 will constitute a vote against Proposal 2.
 
     The Business Combination Proposal, Certificate of Incorporation Amendments,
Stock Plan Amendments and other related matters are more fully described in the
attached Joint Proxy Statement/Prospectus and the Annexes thereto.
 
     The Board of Directors has fixed the close of business on February 23, 1998
as the record date for the determination of the stockholders entitled to notice
of and to vote at the Storage Dimensions Special Meeting and any adjournments or
postponements thereof. Only holders of record of Storage Dimensions Common Stock
on the record date are entitled to vote at the Storage Dimensions Special
Meeting.
 
     If you would like to attend the Storage Dimensions Special Meeting and your
shares are held by a broker, bank or other nominee, you must bring to the
meeting a recent brokerage statement or a letter from the nominee confirming
your beneficial ownership of the shares. You must also bring a form of personal

Meeting, you must obtain from the nominee a proxy issued in your name.

offices of Artecon at 6305 El Camino Real, Carlsbad, California 92009.
 
     At the Artecon Special Meeting, you will be asked to consider and vote upon
a proposal (the "Merger Proposal") to approve the Agreement and Plan of Merger
and Reorganization dated as of December 22, 1997 (the "Reorganization
Agreement"), among Artecon, Storage Dimensions, Inc., a Delaware corporation
("Storage Dimensions"), and Storage Acquisition Corp., a newly formed California
corporation and wholly-owned subsidiary of Storage Dimensions ("Merger Sub"),
and the merger of Merger Sub with and into Artecon, whereby Merger Sub will
cease to exist and Artecon will become a wholly-owned subsidiary of Storage
Dimensions (the "Merger"). As a result of the Merger, each outstanding share of
Artecon Common Stock (other than Dissenting Shares, as defined herein) will be
converted into the right to receive approximately 2.16 shares of Storage
Dimensions Common Stock (the "Exchange Ratio") and each outstanding share of
Artecon Preferred Stock and Artecon Preferred B stock (other than Dissenting
Shares) will be converted into the right to receive one share of newly
designated Storage Dimensions Series A Preferred Stock. Following the Merger,
the former holders of Artecon Common Stock will hold in the aggregate
approximately 13,120,000 shares of Storage Dimensions Common Stock, based upon
the number of shares of Storage Dimensions Common Stock outstanding on February
23, 1998. Such shares would have a value of approximately $52,480,000, based
upon the closing price of Storage Dimensions Common Stock as reported on the
Nasdaq National Market on February 23, 1998. In addition, Storage Dimensions
will issue an aggregate of 2,494,159 shares of Storage Dimensions Series A
Preferred Stock (convertible into a maximum of approximately 831,000 shares of
Storage Dimensions Common Stock) to the holders of Artecon Preferred Stock and
Artecon Preferred B Stock. Immediately following the Merger, the former holders
of Artecon capital stock will hold approximately 62.5% of the outstanding
capital stock of Storage Dimensions and current holders of Storage Dimensions
Common Stock will hold approximately 37.5% of the outstanding capital stock of
Storage Dimensions.
 
     While the percentage of outstanding capital stock of Storage Dimensions to
be held by former holders of Artecon Common Stock and current holders of Storage
Dimensions Common Stock following the Merger is fixed, the exact number of
shares of Storage Dimensions Common Stock issuable to the former Artecon
shareholders (but not shares of Storage Dimensions Preferred Stock) is subject
to modest change based upon changes in the number of outstanding shares of
Storage Dimensions Common Stock and Artecon Common Stock prior to the Merger.
Based upon the number of shares of each company outstanding on February 23,
1998, approximately 2.16 shares of Storage Dimensions Common Stock would be
issued for each share of Artecon Common Stock in the Merger. While dollar
fluctuations in the market price of Storage Dimensions Common Stock will not
affect the Exchange Ratio, they would change the aggregate value of shares of
Storage Dimensions Common Stock issued in the Merger.
 
     In connection with the Merger, Storage Dimensions will amend its
Certificate of Incorporation to (i) change its name to "Artecon, Inc."; and (ii)
designate a new Series A Preferred Stock, consisting of 2,494,159 shares. In
addition, the Storage Dimensions stockholders will also vote on proposals to
provide for a classified Board of Directors whereby the directors will be
separated into three classes with members of each class serving for a three year
term, and to provide that a director may not be removed from office without
cause except, until the third annual meeting of Storage Dimensions following the
Merger, by the affirmative vote of at least 80% of the outstanding voting stock
of Storage Dimensions and by the affirmative vote of at least 66 2/3% of the
outstanding voting stock of Storage Dimensions thereafter.
 
     Upon consummation of the Merger, the name of Storage Dimensions will be
changed to "Artecon, Inc." and the Storage Dimensions Common Stock will be
traded on the Nasdaq National Market under the symbol "ARTE." The Artecon
shareholders will hold shares of a publicly-traded Delaware corporation that is
subject
<PAGE>   7
 
to on-going disclosure obligations under the Securities Exchange Act of 1934, as
amended, including the filing of quarterly and annual reports, current reports
and proxy statements. As stockholders of a Delaware corporation following the
Merger, the rights of the Artecon shareholders will differ from their current
rights as holders of shares of a California corporation.
 
     The Merger Proposal is described more fully in the accompanying Notice of
Special Meeting of Shareholders and Joint Proxy Statement/Prospectus.
 
     If the requisite approvals of the stockholders of Storage Dimensions and
the shareholders of Artecon are received and all other conditions to closing are
satisfied or waived, the Merger is anticipated to close by March 31, 1998.
 
     Holders of Artecon Common Stock and/or Artecon Preferred Stock may, by
complying with Chapter 13 of the California General Corporation Law, be entitled
to dissenters' rights and the receipt of a cash payment for their shares as set
forth therein.
 
     THE BOARD OF DIRECTORS OF ARTECON HAS DETERMINED THAT THE MERGER IS FAIR TO
ARTECON AND IN THE BEST INTERESTS OF ARTECON SHAREHOLDERS. ACCORDINGLY, THE
BOARD OF DIRECTORS OF ARTECON HAS UNANIMOUSLY APPROVED THE REORGANIZATION
AGREEMENT AND THE MERGER AND UNANIMOUSLY RECOMMENDS THAT YOU VOTE IN FAVOR OF
THESE ITEMS.
 
     Your vote is important regardless of how many shares you own. Please take a
few minutes now to review the Joint Proxy Statement/Prospectus and to sign and
date your proxy and return it in the envelope provided. You may attend the
meeting and vote in person even if you have previously returned your proxy.
 
                                          Sincerely,
 
                                          /s/ JAMES L. LAMBERT

                   NOTICE OF SPECIAL MEETING OF SHAREHOLDERS
 
     NOTICE IS HEREBY GIVEN that a Special Meeting of Shareholders of Artecon,
Inc., a California corporation ("Artecon"), will be held at 9:00 a.m. on March
31, 1998 (the "Artecon Special Meeting"), at the corporate offices of Artecon at
6305 El Camino Real, Carlsbad, California 92009.
 
     The meeting is called for the purpose of considering and voting upon a
proposal (the "Merger Proposal") to approve (i) the Agreement and Plan of Merger
and Reorganization dated as of December 22, 1997 (the "Reorganization
Agreement"), among Artecon, Storage Dimensions, Inc., a Delaware corporation
("Storage Dimensions"), and Storage Acquisition Corp., a newly formed California
corporation and wholly-owned subsidiary of Storage Dimensions ("Merger Sub"),
and the merger of Merger Sub with and into Artecon, whereby Merger Sub will
cease to exist and Artecon will become a wholly-owned subsidiary of Storage
Dimensions (the "Merger").
 
     As a result of the Merger, each outstanding share of Artecon Common Stock
(other than Dissenting Shares, as defined herein) will be converted into the
right to receive approximately 2.16 shares of Storage Dimensions Common Stock
(the "Exchange Ratio"), and each outstanding share of Artecon Preferred and
Preferred B stock (collectively, the "Artecon Preferred Stock") (other than
Dissenting Shares) will be converted into the right to receive one share of
newly designated Storage Dimensions Series A Preferred Stock. The Storage
Dimensions Common Stock to be issued to the holders of Artecon Common Stock and
the Storage Dimensions Series A Preferred Stock to be issued to the holders of
Artecon Preferred Stock in the Merger are collectively referred to herein as the
"Merger Consideration." Following the Merger, the former holders of Artecon
Common Stock will hold in the aggregate approximately 13,120,000 shares of
Storage Dimensions Common Stock, based upon the number of shares of Storage
Dimensions Common Stock outstanding on February 23, 1998. Such shares would have
a value of approximately $52,480,000, based upon the closing price of Storage
Dimensions Common Stock as reported on the Nasdaq National Market on February
23, 1998. In addition, Storage Dimensions will issue an aggregate of 2,494,159
shares of Storage Dimensions Series A Preferred Stock (convertible into a
maximum of approximately 831,000 shares of Storage Dimensions Common Stock) to
certain Artecon shareholders. Immediately following the Merger, the former
holders of Artecon capital stock will hold approximately 62.5% of the
outstanding capital stock of Storage Dimensions, and current holders of Storage
Dimensions Common Stock will hold approximately 37.5% of the outstanding capital
stock of Storage Dimensions, in each case, giving effect to the conversion of
the Storage Dimensions Series A Preferred Stock being issued in the Merger and
the exercise of outstanding Storage Dimensions stock options with an exercise
price of less than $3.96875 per share.
 
     In connection with the Merger, Storage Dimensions will amend its
Certificate of Incorporation to (i) change its name to "Artecon, Inc.", and (ii)
designate a new Series A Preferred Stock consisting of 2,494,159 shares. In
addition, Storage Dimensions stockholders will vote upon proposals to provide
(i) for a classified Board of Directors whereby the directors will be separated
into three classes with members of each class serving for a three year term, and
(ii) that a director may not be removed from office without cause except, until
the third annual meeting of Storage Dimensions following the Merger, by the
affirmative vote of at least 80% of the outstanding voting stock of Storage
Dimensions and by the affirmative vote of at least 66 2/3% of the outstanding
voting stock of Storage Dimensions thereafter.
 
     Upon consummation of the Merger, the name of Storage Dimensions will be
changed to "Artecon, Inc." and the Storage Dimensions Common Stock will be
traded on the Nasdaq National Market under the symbol "ARTE." The Storage
Dimensions Series A Preferred Stock will not be publicly traded. The Artecon
shareholders will hold shares of a publicly-traded Delaware corporation that is
subject to on-going disclosure obligations under the Securities Exchange Act of
1934, as amended, including the filing of quarterly and
<PAGE>   9
 
annual reports, current reports and proxy statements. As stockholders of a
Delaware corporation following the Merger, the rights of the Artecon
shareholders will differ from their current rights as shareholders of a
California corporation. A copy of the Reorganization Agreement is attached as
Annex A to the Joint Proxy Statement/Prospectus. A copy of the proposed
amendment to the Storage Dimensions Certificate of Incorporation is attached as
Annex B to this Joint Proxy Statement/Prospectus.
 
     If the requisite approvals of the stockholders of Storage Dimensions and
the shareholders of Artecon are received and all other conditions to the Merger
are satisfied or waived, the Merger is anticipated to close by March 31, 1998.
 
     The Merger Proposal and other related matters are more fully described in
the attached Joint Proxy Statement/Prospectus and the Annexes thereto.
 
     The Board of Directors has fixed the close of business on February 23, 1998
as the record date for the determination of the shareholders entitled to notice
of and to vote at the Artecon Special Meeting and any adjournments or
postponements thereof. Only holders of record of Artecon Common Stock and
Artecon Preferred Stock on the record date are entitled to vote at the Artecon
Special Meeting.
 
     Holders of Artecon Common Stock and/or Artecon Preferred Stock may, by
complying with Chapter 13 of the California General Corporation Law (the
"CGCL"), be entitled to dissenters' rights and the receipt of a cash payment for
their shares as set forth therein, and the shares of Artecon Common Stock and/or
Artecon Preferred Stock held by such persons will be deemed to be "Dissenting
Shares." A copy of Chapter 13 of the CGCL is attached as Annex D to this Joint
Proxy Statement/Prospectus.
 
     If you would like to attend the Artecon Special Meeting and your shares are

                            STORAGE DIMENSIONS, INC.
 
                                   PROSPECTUS
                            ------------------------
 
     This Joint Proxy Statement and Prospectus (the "Joint Proxy
Statement/Prospectus") is being furnished to the stockholders of Storage
Dimensions in connection with the solicitation of proxies by the Board of
Directors of Storage Dimensions (the "Storage Dimensions Board") for use at a
Special Meeting of Stockholders of Storage Dimensions to be held at the

California 95035 on March 31, 1998 at 9:00 a.m., local time, and at any and all

Meeting"). This Joint Proxy Statement/Prospectus also constitutes the Prospectus
of Storage Dimensions with respect to the issuance of shares of Storage
Dimensions Common Stock and shares of Storage Dimensions Series A Preferred
Stock to be issued to shareholders of Artecon. Storage Dimensions Common Stock
is traded on the Nasdaq Stock Market's National Market (the "Nasdaq National
Market") under the symbol "STDM." Upon consummation of the Merger, the name of
Storage Dimensions will be changed to "Artecon, Inc." and the Storage Dimensions
Common Stock will be traded on the Nasdaq National Market under the symbol
"ARTE." On March 6, 1998, the last reported sale price per share of Storage
Dimensions Common Stock on the Nasdaq National Market was $3.75.
 
     This Joint Proxy Statement/Prospectus is also being furnished to the
holders of shares of Artecon Common Stock, no par value (the "Artecon Common
Stock"), holders of shares of Artecon Preferred Stock, no par value, and holders
of shares of Artecon Preferred B Stock, no par value (the Artecon Preferred
Stock and Artecon Preferred B Stock are collectively referred to herein as the
"Artecon Preferred Stock"), in connection with the solicitation of proxies by
the Board of Directors of Artecon (the "Artecon Board") for use at a Special
Meeting of Shareholders of Artecon to be held at the corporate offices of
Artecon at 6305 El Camino Real, Carlsbad, California 92009 on March 31, 1998 at
9:00 a.m., local time, and at any and all adjournments or postponements thereof
(the "Artecon Special Meeting").
 
     Upon consummation of the Merger (i) each issued and outstanding share of
Artecon Common Stock (other than Dissenting Shares, as defined herein) will be
converted into the right to receive approximately 2.16 shares (the "Exchange
Ratio") of Storage Dimensions Common Stock, $.005 par value (the "Storage
Dimensions Common Stock"), (ii) each issued and outstanding share of Artecon
Preferred Stock (other than Dissenting Shares) will be converted into the right
to receive one share of Storage Dimensions Series A Preferred Stock, $.005 par
value (the "Storage Dimensions Preferred Stock"), (iii) each outstanding option,
warrant or other right to purchase Artecon Common Stock, if any, will become an
equivalent right with respect to Storage Dimensions Common Stock, on the same
terms as the original option, warrant or other right, as adjusted by the
Exchange Ratio, (iv) all shares of Artecon Common Stock and Artecon Preferred
Stock will cease to be outstanding and will be canceled and retired and will
cease to exist, and each holder of a certificate formerly representing shares of
Artecon Common Stock and Artecon Preferred Stock will thereafter cease to have
any rights with respect thereto, except the right to receive certificates
representing the shares of Storage Dimensions Common Stock and Storage
Dimensions Preferred Stock, respectively, and (v) Artecon will become a
wholly-owned subsidiary of Storage Dimensions. In connection with the Merger,
Storage Dimensions will amend its Certificate of Incorporation to: (i) change
its name to "Artecon, Inc."; (ii) subject to approval of Proposal 2 below,
provide for a classified Board of Directors whereby the directors
<PAGE>   11
 
will be separated into three classes with members of each class serving for a
three year term; (iii) subject to approval of Proposal 3 below, provide that a
director may not be removed from office without cause except, until the third
annual meeting of the stockholders of Storage Dimensions following the Merger,
by the affirmative vote of at least 80% of the outstanding voting stock of
Storage Dimensions and by the affirmative vote of at least 66 2/3% of the
outstanding voting stock of Storage Dimensions thereafter; and (iv) designate a
new Series A Preferred Stock, consisting of 2,494,159 shares. In the Business
Combination, Storage Dimensions will issue an aggregate of approximately
13,120,000 shares of Storage Dimensions Common Stock to the Artecon
shareholders, based upon the number of shares of Storage Dimensions Common Stock
outstanding on February 23, 1998. Such shares would have a value of
approximately $52,480,000, based upon the closing price of Storage Dimensions
Common Stock as reported on the Nasdaq National Market on February 23, 1998. In
addition, Storage Dimensions will issue an aggregate of 2,494,159 shares of
Storage Dimensions Preferred Stock (convertible into a maximum of approximately
831,000 shares of Storage Dimensions Common Stock) to certain Artecon
shareholders, which shares of Storage Dimensions Preferred Stock will not be
publicly traded. Immediately following the Merger, the former holders of Artecon
capital stock will hold approximately 62.5% of the outstanding capital stock of
Storage Dimensions and current holders of Storage Dimensions Common Stock will
hold approximately 37.5% of the outstanding capital stock of Storage Dimensions,
in each case giving effect to the conversion of the Storage Dimensions Series A
Preferred Stock being issued in the Merger and the exercise of outstanding
Storage Dimensions stock options with an exercise price of less than $3.96875
per share.
 
     While the percentage of outstanding capital stock of Storage Dimensions to
be held by former holders of Artecon Common Stock and the current holders of
Storage Dimensions Common Stock following the Business Combination is fixed, the
exact number of shares of Storage Dimensions Common Stock issuable to the former
Artecon shareholders (but not shares of Storage Dimensions Preferred Stock) is
subject to modest change based upon changes in the number of outstanding shares
of Storage Dimensions Common Stock and Artecon Common Stock prior to the
Business Combination. Based upon the number of shares of each company
outstanding on February 23, 1998, approximately 2.16 shares of Storage
Dimensions Common Stock would be issued for each share of Artecon Common Stock
in the Business Combination. While dollar fluctuations in the market price of
Storage Dimensions Common Stock will not affect the Exchange Ratio, they would
change the aggregate value of shares of Storage Dimensions Common Stock issued
in the Business Combination.
 
     Consummation of the Merger is subject to various conditions, including the
approval and adoption of the Reorganization Agreement and approval of the Merger
by holders of a majority of the outstanding shares of Artecon Common Stock and
Artecon Preferred Stock, each voting as a separate class, at the Artecon Special
Meeting and the approval of the Business Combination Proposal and the
Certificate of Incorporation Amendments at the Storage Dimensions Special
Meeting by the affirmative vote of a majority of the outstanding shares of
Storage Dimensions Common Stock. Certain holders of Artecon capital stock, who
together hold approximately 66.6% and 99.2% of the outstanding Artecon Common
Stock and Artecon Preferred Stock, respectively, have agreed to vote such shares
in favor of the Reorganization Agreement and the Merger and have granted Storage
Dimensions an irrevocable proxy to vote their shares of Artecon Common Stock and
Artecon Preferred Stock in favor of the Reorganization Agreement and the Merger.
In addition, certain holders of Storage Dimensions Common Stock, who together
hold approximately 56.7% of the outstanding Storage Dimensions Common Stock,
have agreed to vote such shares of Storage Dimension Common Stock in favor of
the Business Combination Proposal and have granted Artecon an irrevocable proxy
to vote their shares of Storage Dimensions Common Stock in favor of the Business
Combination Proposal. See "OTHER AGREEMENTS -- Artecon Voting Agreements" and
"-- Storage Dimensions Voting Agreements."
 
     Holders of Artecon Common Stock and/or Artecon Preferred Stock may, by
complying with Chapter 13 of the CGCL, be entitled to dissenters' rights and the
receipt of a cash payment for their shares as set forth therein, and the shares
of Artecon Common Stock and Artecon Preferred Stock held by such persons will be
deemed to be "Dissenting Shares." Storage Dimensions stockholders do not have
dissenters' or appraisal rights under Delaware law as a result of the Merger.

financial performance and condition, accounting and tax treatment and the extent

not statements of historical fact may be deemed to be forward-looking
statements. Without limiting the foregoing, the words "projects," "believes,"
"anticipates," "plans," "expects," "intends" and similar expressions are
intended to identify forward-looking statements. There are a number of important
factors that could cause the results of the combined company to differ
materially from those indicated by such forward-looking statements, including,
but not limited to, (i) factors related to the Merger, including the risk that
anticipated synergies will not be realized, the significant transaction charges
and the potential dilutive effect to holders of Storage Dimensions Common Stock
and Artecon capital stock which will result from the Merger, the effect of the
Merger on customers and partners of Storage Dimensions and Artecon and (ii)
factors related to Storage Dimensions' and Artecon's businesses including
history of operating losses and uncertain profitability, significant
fluctuations in operating results, the dependence on the server market in
general and storage systems in particular, the ability to develop and ship
planned products incorporating technological advancements, the ability to
recruit, train and retain qualified sales and other personnel, product liability
and insurance, as well as those additional factors set forth in this Joint Proxy
Statement/Prospectus under the caption "RISK FACTORS." Neither Storage
Dimensions nor Artecon undertakes any obligation to update any forward-looking
statements.

THE PARTIES
 
  Storage Dimensions, Inc.
 
     Storage Dimensions designs, manufactures, markets and supports
high-performance data storage systems for open systems network applications.
Storage Dimensions focuses on the Intel-based local area network market (the
"PC-LAN market") by developing and marketing a broad family of disk and tape
storage systems that are designed to satisfy the high-performance,
fault-tolerance and high-availability (minimum downtime) requirements of its
customers while at the same time reducing life-cycle cost of ownership. In line
with its open systems strategy, Storage Dimensions also develops and supports
selected products for the UNIX market. Storage Dimensions products are sold
through its own field sales force in combination with multi-tiered distribution
channels. Storage Dimensions currently expects its revenues for the fiscal
quarter ending March 31, 1998 to be significantly less than its results of
operations for the fourth quarter of 1997 and for the first quarter of 1997.
Storage Dimensions attributes the decline to a combination of uncertainty in the
marketplace resulting from Storage Dimensions' announcement of the Merger in
late 1997 and continued sales force productivity issues.
 
     Storage Dimensions was incorporated in the State of Delaware in November
1992. In an acquisition effected on December 26, 1992 (the "Storage
Acquisition"), Storage Dimensions acquired the assets and assumed the
liabilities of the "Storage Dimensions" subsidiary of Maxtor Corporation
("Maxtor") for an aggregate purchase price of $21.4 million. The Storage
Acquisition was financed through equity investments in Storage Dimensions made
by Capital Partners, Inc. ("Capital Partners") and certain of its affiliates
(collectively, the "Capital Partners Group"), by certain members of Storage
Dimensions' management and by Maxtor. In March 1997, Storage Dimensions
completed its initial public offering. Storage Dimensions' address is 1656
McCarthy Boulevard, Milpitas, California 95035 and its telephone number is (408)
954-0710.
 
  Artecon, Inc.
 
     Artecon designs, manufactures, markets and supports a broad range of
scalable, fully integrated data storage products for the open-systems computing
environment. Artecon has established itself as a leader in the design,
manufacture and sale of third-party mass storage and enhancement products in the
Sun Microsystems ("Sun") and UNIX markets, offering both host-attached and
network-attached storage solutions for a broad range of customers. Artecon's
enterprise storage product line includes scalable RAID systems which allow users
to grow modularly from a single mass storage device to over ten terabytes (10TB)
of rack-mounted, fault-tolerant mass storage, thereby meeting the capacity and
performance needs of a wide range of customers while protecting and maintaining
customer investment. Artecon's telecommunications infrastructure storage
products represent what Artecon believes is the industry's only fully
NEBS-certified, multi-terabyte solution for high-end, application-specific needs
of telecommunications and government customers using commercial off-the-shelf
("COTS") workstation technology. Artecon also markets rackmount solutions for
COTS workstations and servers and provides systems integration and a variety of
other service and support programs. Artecon currently expects its revenues for
the fiscal quarter ending March 31, 1998 to be significantly less than its
results of operations for the quarter ended December 31, 1997. Artecon
attributes the decline primarily to post-holiday seasonal sales declines and
uncertainty in the marketplace resulting from the announcement of the Merger in
late 1997.
 
                                        3

     In August 1997, Artecon acquired substantially all of the assets and
liabilities of Falcon Systems, Inc. ("Falcon"), a network-attached storage
server integrator and storage peripherals reseller, in a transaction accounted
for as a purchase. The Falcon acquisition enabled Artecon to achieve several
important strategic objectives, including the acquisition of Artecon's
AerREAL(TM) real-time specialized file server software and other complementary
products to better serve Artecon's existing customers, the expansion of
Artecon's customer base in the UNIX, Windows NT and Windows 95 markets and a
significant expansion of Artecon's revenue base.
 
     The principal executive offices of Artecon are located at 6305 El Camino
Real, Carlsbad, California 92009 and its telephone number is (760) 931-5500.
 
  Storage Acquisition Corp.
 
     Merger Sub is a California corporation recently organized for the sole
purpose of effecting the Merger. Merger Sub is a wholly-owned subsidiary of
Storage Dimensions, has no material assets and has not engaged in any activities
except in connection with the Merger.
 
     The principal executive offices of Merger Sub are located at 1656 McCarthy
Boulevard, Milpitas, California 95035 and its telephone number is (408)
954-0710.

RECOMMENDATIONS OF THE BOARDS OF DIRECTORS
 
     The Storage Dimensions Board. The Storage Dimensions Board has unanimously
approved the Business Combination Proposal and the Certificate of Incorporation
Amendments and has determined that the Merger is in the best interests of
Storage Dimensions and its stockholders and recommends approval of the Business
Combination Proposal and the Certificate of Incorporation Amendments by the
stockholders of Storage Dimensions. The primary factors considered and relied
upon by the Storage Dimensions Board in reaching its recommendation are
described below under "THE MERGER -- Recommendation of the Storage Dimensions
Board; Storage Dimensions Reasons for the Merger." The Storage Dimensions Board
has also unanimously approved the Stock Plan Amendments and recommends approval
thereof.
 
     The Artecon Board. The Artecon Board has unanimously approved the Merger
Proposal and has determined that the Merger is in the best interests of Artecon
and its shareholders and recommends approval of the Merger Proposal by the
shareholders of Artecon. The primary factors considered and relied upon by the
Artecon Board in reaching its recommendation are described below under "THE
MERGER -- Recommendation of the Artecon Board; Artecon Reasons for the Merger."
 
THE MERGER
 
  General
 
     Pursuant to the Reorganization Agreement, Merger Sub will be merged with
and into Artecon, whereby Merger Sub will cease to exist and Artecon will become
a wholly owned subsidiary of Storage Dimensions. The Merger will occur on the
date of filing and acceptance of a certificate of merger with the Secretary of
State of the State of California (the "Effective Date"), which is anticipated to
occur on or about March 31, 1998. See "THE MERGER -- Effective Time."
 
  Merger Consideration
 
     In the Merger, Storage Dimensions will issue an aggregate of approximately
13,120,000 million shares of Storage Dimensions Common Stock to the Artecon
shareholders. Such shares would have a value of approximately $52,480,000, based
upon the closing price of Storage Dimensions Common Stock as reported on the
Nasdaq National Market on February 23, 1998. In addition, Storage Dimensions
will issue an aggregate of 2,494,159 shares of Storage Dimensions Series A
Preferred Stock to certain Artecon shareholders, which shares will not be
publicly traded. Immediately following the Business Combination, the former
holders of Artecon capital stock will hold approximately 62.5% of the
outstanding capital stock of Storage Dimensions and the current holders of
Storage Dimensions Common Stock will hold approximately 37.5% of the outstanding
capital stock of Storage Dimensions, in each case, giving effect to the
conversion of the Storage Dimensions Series A Preferred Stock being issued in
the Merger and the exercise of outstanding Storage Dimensions stock options with
an exercise price of less than $3.96875 per share. While the percentage of
outstanding capital stock of Storage Dimensions to be held by former holders of
Artecon Common Stock and current holders of Storage Dimensions Common Stock
following the Merger is fixed, the exact number of shares of Storage Dimensions
Common Stock issuable to the former Artecon shareholders (but not shares of
Storage Dimensions Preferred Stock) is subject to modest change based upon
changes in the number of outstanding shares of Storage Dimensions Common Stock
and Artecon Common Stock prior to the Merger. Based upon the number of shares of
each company outstanding on February 23, 1998, approximately
 
                                        6
<PAGE>   22
 
2.16 shares of Storage Dimensions Common Stock would be issued for each share of
Artecon Common Stock in the Merger. While dollar fluctuations in the market
price of Storage Dimensions Common Stock will not affect the Exchange Ratio,
they would change the aggregate value of shares of Storage Dimensions Common
Stock issued in the Merger.
 
     More specifically, the exact number of shares of Storage Dimensions Common
Stock into which each share of Artecon Common Stock will be converted will be
determined as of the Effective Time as follows: the Exchange Ratio will be a
fraction the numerator of which is the number of Merger Shares (as defined
below) and the denominator of which is the number of Artecon Shares (as defined
below). "Merger Shares" shall mean the shares of Storage Dimensions Common Stock
to be issued to holders of Artecon Common Stock in the Merger and shall be equal
to the product of (A) 1.5641 (the "Applicable Multiple") times (B) the sum of
(x) the number of shares of Storage Dimensions Common Stock outstanding
immediately prior to the Effective Time plus (y) the maximum number of shares of
Storage Dimensions Common Stock issuable upon exercise of any options to
purchase Storage Dimensions Common Stock (without regard to vesting) with option
exercise prices of less than $3.96875. "Artecon Shares" shall mean the sum of
(A) the number of shares of Artecon Common Stock outstanding immediately prior
to the Effective Time plus (B) the maximum number of shares of Artecon Common
Stock underlying any instruments convertible into or exchangeable for Artecon
Common Stock (without regard to vesting) outstanding immediately prior to the
Effective Time, including shares of Artecon Preferred Stock other than the
2,494,159 shares of Artecon Preferred Stock held by W.R. Sauey and certain
affiliates of W.R. Sauey. Such shares of Artecon Preferred Stock held by W.R.
Sauey and such affiliates (the "Sauey Preferred") will be converted into
2,494,159 shares of Storage Dimensions Preferred Stock pursuant to the Merger,
as described below. Although the Applicable Multiple is fixed, the Exchange
Ratio is subject to modest change based upon changes in the number of shares of
Storage Dimensions Common Stock and Artecon Common Stock outstanding immediately
prior to the Effective Time.
 
     The Sauey Preferred will constitute all of the shares of Artecon Preferred
Stock outstanding as of the Effective Time. Each share of Sauey Preferred
outstanding as of the Effective Time shall be converted into the right to
receive one share of Storage Dimensions Preferred Stock. All current holders of
Artecon Preferred Stock, other than the Sauey Preferred, have agreed to convert
such Artecon Preferred Stock into shares of Artecon Common Stock prior to the
Effective Time pursuant to their rights under Artecon's Articles of
Incorporation, which shares will then be converted into Storage Dimensions
Common Stock pursuant to the Merger. Former Artecon shareholders will receive
cash in lieu of any fractional shares of Storage Dimensions Common Stock to
which such Artecon shareholders would otherwise have been entitled. See "THE
REORGANIZATION AGREEMENT -- Terms of the Merger."
 
  Amendments to Storage Dimensions Certificate of Incorporation
 
     Approval of the Business Combination Proposal by Storage Dimensions
stockholders will also constitute approval of an amendment to the Storage
Dimensions Certificate of Incorporation to (i) change its name to "Artecon,
Inc."; and (ii) designate a new Series A Preferred Stock, consisting of
2,494,159 shares. In addition, subject to the approval of the Certificate of
Incorporation Amendments by Storage Dimensions stockholders, Storage Dimensions
will amend its Certificate of Incorporation to provide for a classified Board of
Directors whereby the directors will be separated into three classes with
members of each class serving for a three year term and to provide that a
director may not be removed from office without cause except, until the third
annual meeting of stockholders of Storage Dimensions following the Merger, by
the affirmative vote of at least 80% of the outstanding voting stock of Storage
Dimensions and by the affirmative vote of at least 66 2/3% of the outstanding
voting stock of Storage Dimensions thereafter.
 
  Effect on Artecon Stock Options, Warrants or Rights
 
     At the Effective Time, each outstanding option, warrant and right to
purchase Artecon Common Stock, if any, will be assumed by Storage Dimensions and
each such option, warrant or right will be deemed to constitute an option,
warrant or other right to acquire, on the same terms and conditions as were
applicable to

such Artecon option, warrant or right as of the Effective Time, the number
(rounded down to the nearest whole number) of shares of Storage Dimensions
Common Stock that the holder of such option, warrant or right would have been
entitled to receive pursuant to the Merger had such holder exercised the Artecon
option, warrant or right in full immediately prior to the Effective Time (not
taking into account whether or not such option was in fact exercisable), at a
price per share equal to the exercise price under such Artecon option, warrant
or right divided by the Exchange Ratio (rounded up to the nearest whole cent).
See "THE MERGER -- Effect on Artecon Options, Warrants and Rights" and "THE
REORGANIZATION AGREEMENT -- Terms of the Merger -- Artecon Options, Warrants and
Rights."
 
  Effect on Storage Dimensions Stock Options
 
     At the Effective Time, all Storage Dimensions stock options, other than
those granted after December 22, 1997, will become fully vested and exercisable
as a result of the Merger. Such options will remain outstanding for the
remainder of their original term (subject to earlier termination in the event
that an optionee's service relationship with Storage Dimensions is terminated).
The number of shares subject to outstanding Storage Dimensions options and the
exercise price thereof will remain unchanged.
 
  Conditions to the Merger; Termination; Fees
 
     The consummation of the Merger is subject to various conditions, including:
(i) approval by the stockholders of Storage Dimensions and the shareholders of
Artecon; (ii) the absence of any legal restraints or prohibitions preventing the
consummation of the Merger, including compliance with the Hart-Scott-Rodino
Antitrust Improvements Act of 1976, as amended; (iii) receipt of opinions of
legal counsel as to the tax treatment of the Merger; (iv) the listing on the
Nasdaq National Market of the Storage Dimensions Common Stock to be issued in
the Merger; and (v) the filing of the Certificate of Amendment in the form
attached to the Reorganization Agreement, which includes the Certification of
Incorporation Amendments. See "THE MERGER -- Stock Listing" and "THE
REORGANIZATION AGREEMENT -- Conditions to the Merger."
 
     The Reorganization Agreement may be terminated under certain circumstances
but may not be terminated by either Storage Dimensions or Artecon as a result of
fluctuations in the market price per share of Storage Dimensions Common Stock.
In addition, Storage Dimensions and Artecon have agreed that, if the
Reorganization Agreement is terminated under certain circumstances, the
terminating party will be obligated to pay the other party a sum of $1.5
million, together with out-of-pocket costs. See "THE REORGANIZATION
AGREEMENT -- Termination of the Reorganization Agreement" and "-- Termination
Fees."
 
  Exchange of Artecon Stock Certificates
 
     At or as soon as practicable after the Effective Time, holders of Artecon
Common Stock and Artecon Preferred Stock will surrender their certificates
representing such Artecon capital stock in exchange for certificates
representing Storage Dimensions Common Stock or Storage Dimensions Preferred
Stock, as the case may be. Holders of Artecon capital stock will receive a cash
payment in lieu of fractional shares, if any. See "THE REORGANIZATION
AGREEMENT -- Exchange of Certificates."
 
  No Solicitation
 
     Pursuant to the Reorganization Agreement, except under certain limited
circumstances, each of Storage Dimensions and Artecon has agreed not to (i)
solicit, initiate, encourage or induce the making, submission or announcement of
any alternate acquisition proposal, (ii) furnish any information regarding
itself or any of its subsidiaries to any other party in connection with any
alternate acquisition proposal, (iii) participate in any discussions or
negotiations with any other parties with respect to an alternate acquisition
proposal, or (iv) enter into any letter of intent or similar document or any
other contract relating to an alternate acquisition proposal. See "THE
REORGANIZATION AGREEMENT -- No Solicitation."

  Dissenters' and Appraisal Rights
 
     If the Merger is approved by the required vote of Artecon shareholders and
Storage Dimensions stockholders and is not abandoned or terminated, holders of
Artecon capital stock who did not vote in favor of the Merger Proposal may, by
complying with Sections 1300 through 1312 of the CGCL, be entitled to
dissenters' rights and to cash payments for their shares as described therein. A
copy of Chapter 13 of the CGCL is attached hereto as Annex D. Under the Delaware
General Corporation Law (the "DGCL"), Storage Dimensions stockholders are not
entitled to dissenters' rights or appraisal rights with respect to the proposed
Merger.
 
     Under Delaware law, Storage Dimensions stockholders are not entitled to
appraisal rights. After the Merger, such stockholders would continue to hold the
same number of shares of Storage Dimensions Common Stock as they held before the
Merger. See "THE MERGER -- Appraisal and Dissenters' Rights."
 
  Accounting Treatment
 
     For accounting purposes, the Merger will be treated as a purchase of
Storage Dimensions by Artecon since the holders of Artecon capital stock would
hold and have voting power with respect to approximately 62.5% of the total
issued and outstanding voting capital stock of Storage Dimensions immediately
following the Merger. See "THE MERGER -- Accounting Treatment."
 
  Stock Ownership Following the Merger
 
     Based upon the capitalization of Storage Dimensions as of the close of
business on the Storage Dimensions Record Date, an aggregate of approximately
13,120,000 shares of Storage Dimensions Common Stock will be issued to holders
of Artecon Common Stock in the Merger. In addition, in the Merger, Storage
Dimensions will issue an aggregate of 2,494,159 shares of Storage Dimensions
Preferred Stock to certain holders of Artecon Preferred Stock. Such Storage
Dimensions Preferred Stock will be convertible into a maximum of approximately
831,000 shares of Storage Dimensions Common Stock at any time after January 1,
1999. Based upon (i) the number of shares of Storage Dimensions Common Stock
issued and outstanding as of the Storage Dimensions Record Date, (ii) the
issuance of Storage Dimensions Common Stock in the Merger, (iii) the conversion
of the Storage Dimensions Preferred Stock issued in the Merger into Storage
Dimensions Common Stock, and (iv) the exercise of Storage Dimensions stock
options with an exercise price of less than $3.96875 per share, the former
holders of Artecon capital stock and the current holders of Storage Dimensions
Common Stock would hold, and would have voting power with respect to,
approximately 62.5% and 37.5%, respectively, of Storage Dimensions' outstanding
capital stock. The foregoing number of shares of Storage Dimensions capital
stock to be issued in the Merger is subject to adjustment to reflect any changes
in the capitalization of Storage Dimensions subsequent to the Storage Dimensions
Record Date. See "STOCK OWNERSHIP OF STORAGE DIMENSIONS FOLLOWING THE MERGER."
 
  Risk Factors
 
     See "RISK FACTORS" for a discussion of certain risk factors pertaining to
the Merger and the businesses of Storage Dimensions and Artecon.
 
  Opinion of Financial Advisor
 
     Smith Barney Inc. (now associated with Salomon Brothers Inc and
collectively with Salomon Brothers Inc, doing business as, and referred to
herein as, "Salomon Smith Barney") has acted as financial advisor to Storage
Dimensions in connection with the Merger and has delivered to the Storage
Dimensions Board a written opinion dated December 22, 1997 to the effect that,
as of the date of such opinion and based upon and subject to certain matters
stated therein, the Merger Consideration was fair, from a financial point of
view, to Storage Dimensions. The full text of the written opinion of Salomon
Smith Barney dated December 22, 1997, which sets forth the assumptions made,
matters considered and limitations on the review undertaken, is attached as
Annex C to this Joint Proxy Statement/Prospectus and should be read carefully in
its entirety. THE OPINION OF SALOMON SMITH BARNEY IS DIRECTED TO THE STORAGE
DIMENSIONS BOARD AND RELATES ONLY TO THE
 
                                        9
<PAGE>   25
 
FAIRNESS OF THE MERGER CONSIDERATION FROM A FINANCIAL POINT OF VIEW TO STORAGE
DIMENSIONS, DOES NOT ADDRESS ANY OTHER ASPECT OF THE MERGER OR RELATED
TRANSACTIONS AND DOES NOT CONSTITUTE A RECOMMENDATION TO ANY STOCKHOLDER AS TO
HOW SUCH STOCKHOLDER SHOULD VOTE AT THE STORAGE DIMENSIONS SPECIAL MEETING. See
"THE MERGER -- Opinion of Financial Advisor." Salomon Smith Barney's opinion
does not address the fairness of the Merger Consideration from a financial point
of view to the stockholders of Storage Dimensions since the stockholders of
Storage Dimensions will not be asked to convert their shares of Storage
Dimensions Common Stock in the Merger.
 
     Artecon elected not to retain a financial advisor or obtain a fairness
opinion in connection with the Merger. The Artecon Board believed that it had
considered all material factors which were relevant to its approval of the
Merger and did not believe that the economic cost of retaining a financial
advisor and obtaining a fairness opinion was justified under the circumstances.
 
  Interests of Certain Persons in the Merger
 
     In considering the respective recommendations of the Artecon Board and
Storage Dimensions Board with respect to the Merger, the Artecon shareholders
and Storage Dimensions stockholders should be aware that certain members of the
Artecon Board and the Storage Dimensions Board and the executive officers of
each company have certain interests in the Merger that are in addition to the
interests of the shareholders generally.
 
     In particular, pursuant to the Reorganization Agreement, James Lambert,
Jason Sauey and W.R. Sauey, current directors of Artecon, will become members of
the Storage Dimensions Board at the Effective Time. Current Storage Dimensions
directors Chong Sup Park and Brian Fitzgerald will remain on the Board. In
addition, James Lambert, Tesfaye Hailemichael and Dana Kammersgard, currently
President and Chief Executive Officer, Chief Financial Officer and a director,
respectively, of Artecon, will serve as President and Chief Executive Officer,
Chief Financial Officer and Secretary, respectively, of Storage Dimensions
following the Merger.
 
     In addition, in connection with the Merger, Storage Dimensions and each of
David Eeg and Robert Bylin, the President and Chief Executive Officer and the
Chief Financial Officer of Storage Dimensions, respectively, amended the
employment agreements of such persons to provide certain severance benefits upon
termination of their relationship with Storage Dimensions. Moreover, as a result
of the Merger, stock options held by all Storage Dimensions employees, including
executive officers (but excluding options granted after December 22, 1997), will
become fully vested and exercisable. See "CERTAIN RELATIONSHIPS AND RELATED
TRANSACTIONS OF STORAGE DIMENSIONS" and "THE MERGER -- Effect on Storage
Dimensions Options."
 
     W.R. Sauey, a director of Artecon, and certain entities affiliated with Mr.
Sauey, are the owners of 2,494,159 shares of Artecon Preferred Stock and will
receive all of the Storage Dimensions Preferred Stock being issued in the
Merger.
 
  Governmental Approvals
 
     The consummation of the Merger is subject to the expiration or termination
of the relevant waiting period under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976, as amended (the "HSR Act"). Storage Dimensions and Mr.
W.R. Sauey, a principal shareholder of Artecon, have filed notification and
report forms under the HSR Act. Effective February 13, 1998, the waiting period
under the HSR Act was terminated. See "OTHER MATTERS -- Regulatory Approvals
Required."
 
  Certain Federal Income Tax Consequences
 
     It is expected that the Merger will constitute a tax-free reorganization
for federal income tax purposes and, accordingly, that no gain or loss will be
recognized for federal income tax purposes by the Artecon shareholders upon the
conversion of Artecon Common Stock into Storage Dimensions Common Stock or upon
the conversion of Artecon Preferred Stock into Storage Dimensions Preferred
Stock in the Merger (except with respect to any cash received in lieu of any
fractional share interest of Storage Dimensions
 
                                       10

Common Stock or for Dissenting Shares). The obligations of Storage Dimensions
and Artecon to consummate the Merger are conditioned on the receipt by Storage
Dimensions of an opinion from Wilson Sonsini Goodrich & Rosati, P.C. and the
receipt by Artecon of an opinion from Cooley Godward LLP, that the Merger
constitutes a reorganization under Section 368 of the Internal Revenue Code of
1986, as amended (the "Code"). See "THE MERGER -- Certain Federal Income Tax
Consequences." ARTECON SHAREHOLDERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS
AS TO THE SPECIFIC TAX CONSEQUENCES TO THEM RESULTING FROM THE MERGER.
 
  Additional Matters for Consideration by Storage Dimensions Stockholders
 
     At the Storage Dimensions Special Meeting, Storage Dimensions stockholders
will also be asked to consider and vote upon (i) the Certificate of
Incorporation Amnendments, (ii) an amendment to the Storage Dimensions 1996
Stock Option Plan to increase the number of shares issuable thereunder from
1,000,000 to 3,000,000 and (iii) an amendment to the Storage Dimensions 1996
Employee Stock Purchase Plan to increase the number of shares issuable
thereunder from 200,000 to 400,000.
 
  Comparative Rights of Stockholders
 
     For a discussion of various differences between the rights of the Artecon
shareholders and the rights of the Storage Dimensions stockholders, see

Stock" and "-- Description of Artecon Capital Stock" and "COMPARISON OF RIGHTS
OF HOLDERS OF STORAGE DIMENSIONS CAPITAL STOCK AND ARTECON CAPITAL STOCK."

     The table below sets forth, for the fiscal quarters indicated, the reported
high and low closing sales prices of Storage Dimensions Common Stock on the
Nasdaq National Market.

     There is no public market for Artecon's capital stock. On December 31,
1997, the last reported sale price reported on the Nasdaq National Market for
the Storage Dimensions Common Stock was $3.75 per share. See "RISK
FACTORS -- Volatility of Stock Prices, Absence of Public Market for Preferred
Stock."
 
     On December 19, 1997, the last full trading day prior to the execution and
delivery of the Reorganization Agreement and the public announcement thereof,
the last reported sales price of Storage Dimensions Common Stock was $4.00 per
share. On March 6, 1998, the last reported sales price of Storage Dimensions
Common Stock the Nasdaq National Market was $3.75 per share. Based on an
Exchange Ratio of approximately 2.16 shares of Storage Dimensions Common Stock
for each share of Artecon Common Stock, the pro forma equivalent market value of
Artecon Common Stock on March 6, 1998 was $8.10 per share.
 
     Because the market price of Storage Dimensions Common Stock is subject to
fluctuation, the market value of the shares of Storage Dimensions Common Stock
that holders of Artecon Common Stock will receive in the Merger may increase or
decrease prior to the Merger (provided, however, that the number of shares of
Storage Dimensions Common Stock issuable in the Merger will not be affected by
any changes in the market price of Storage Dimensions Common Stock).
 
     HOLDERS OF ARTECON CAPITAL STOCK ARE URGED TO OBTAIN A CURRENT MARKET
QUOTATION FOR STORAGE DIMENSIONS COMMON STOCK.
 
     Neither Storage Dimensions nor Artecon has paid any cash dividends in the
past, and each currently intends to retain future earnings, if any, to fund the
development and growth of its business and not to pay any cash dividends in the
foreseeable future.

          UNAUDITED PRO FORMA COMBINED CONDENSED FINANCIAL STATEMENTS
 
     The pro forma information is presented for illustrative purposes only and
is not necessarily indicative of the operating results or financial position
that would have occurred if the Merger had been consummated, nor is it
necessarily indicative of future operating results or financial position. The
unaudited pro forma combined financial statements have been derived from the
historical consolidated financial statements of Artecon and Storage Dimensions
and give effect to (i) the Merger as a reverse acquisition and a purchase of
Storage Dimensions by Artecon for accounting purposes, and (ii) costs associated
with the consummation of the Merger. The unaudited pro forma combined balance
sheet gives effect to the combination as if it had occurred on December 31, 1997
using Artecon's and Storage Dimensions' December 31, 1997 consolidated financial
statements. The unaudited pro forma combined statements of operations give
effect to the combination as if it had occurred (i) on April 1, 1997, the
beginning of the earliest period presented and (ii) at the beginning of the last
full fiscal year for each company. The pro forma adjustments are based on
preliminary estimates, available information and certain assumptions that
management deems appropriate. The pro forma financial information does not
purport to represent what the combined company's financial position or results
of operations would actually have been if such transactions in fact had occurred
on those dates or to project the combined company's financial position or
results of operations for any future period. The unaudited pro forma combined
financial statements should be read in conjunction with Artecon's and Storage
Dimensions' consolidated financial statements and the notes thereto included
elsewhere herein.

                           COMPARATIVE PER SHARE DATA
 
     The following table sets forth certain historical per share data of Storage
Dimensions and Artecon and combined per share data on an unaudited pro forma
basis after giving effect to the Merger as a purchase of Storage Dimensions by
Artecon assuming the Merger had been effected during the periods presented. This
data should be read in conjunction with the selected financial data, the
unaudited pro forma combined financial information and the separate historical
financial statements of Storage Dimensions and Artecon, and notes thereto,
included elsewhere in this Joint Proxy Statement/Prospectus. The pro forma
combined financial data is not necessarily indicative of the operating results
that would have been achieved had the Merger been consummated as of the
beginning of the periods indicated nor is such data necessarily indicative of
future financial condition or results of operations. For purposes of the
comparative per share data, Storage Dimensions' financial data at December 31,
1996 has been combined with Artecon's financial data at March 31, 1997.

(1) The historical book value per share is computed by dividing stockholders'
    equity by the number of shares of Common Stock (and all shares of Preferred
    Stock on an as-if-converted basis).
 
(2) The Pro Forma Combined Book Value Per Share is computed by dividing pro
    forma stockholders' equity by the pro forma number of shares of Storage
    Dimensions Common Stock or Artecon Common Stock (including all shares of
    Preferred Stock on an as-if-converted basis) outstanding at the end of each
    period.
 
(3) The Artecon Equivalent Pro Forma Combined Per Share amounts are calculated
    by multiplying the Artecon combined pro forma per share amounts by an
    assumed Exchange Ratio of 2.16 per share of Artecon Common Stock.
 
(4) Preferred shares are excluded from the pro forma net loss per share
    computations due to their anti-dilutive nature.

                                  RISK FACTORS
 
     Storage Dimensions Stockholders and Artecon Shareholders should carefully
consider the following matters in conjunction with the other information
included in this Joint Proxy Statement/Prospectus in determining how to vote.
 
     The discussion in this Joint Proxy Statement/Prospectus contains
forward-looking statements that involve risks and uncertainties. Storage
Dimensions', Artecon's and the combined company's actual results could differ
materially from those discussed here. Factors that could cause or contribute to
such differences include, but are not limited to, those discussed below and in
the sections entitled "Storage Dimensions Management's Discussion and Analysis
of Financial Condition and Results of Operations," "Storage Dimensions
Business," "Artecon Management's Discussion and Analysis of Financial Condition
and Results of Operations" and "Artecon Business," as well as those discussed
elsewhere in this Joint Proxy Statement/Prospectus.
 
RISKS RELATING TO THE MERGER
 
     EXCHANGE RATIO NOT DEPENDENT UPON CHANGES IN STORAGE DIMENSIONS STOCK
PRICE. While the Exchange Ratio is subject to change based on changes in the
number of shares of Storage Dimensions Common Stock and Artecon Common Stock
prior to the Effective Time, the Applicable Multiple and the one-for-one
exchange of Storage Dimensions Preferred Stock for Artecon Preferred Stock are
fixed and will not be adjusted in the event of any increase or decrease in the
market price of Storage Dimensions Common Stock. While dollar fluctuations in
the market price of Storage Dimensions Common Stock will not affect the Exchange
Ratio, they would change the aggregate value of the shares of Storage Dimensions
Common Stock issued in the Merger. The market price of Storage Dimensions Common
Stock at the Effective Time may vary from its price on the date of this Joint
Proxy Statement/Prospectus and on the date of the Storage Dimensions Special
Meeting and the Artecon Special Meeting. Such variations may be the result of
changes in the business, operations or prospects of Storage Dimensions, market
assessments of the likelihood that the Merger will be consummated, the timing
thereof and the prospects of the Merger and post-Merger operations, regulatory
considerations, general market and economic conditions and other factors. In the
event that the market price of Storage Dimensions Common Stock decreases or
increases prior to the Effective Time, the value at the Effective Time of
Artecon capital stock would correspondingly decrease or increase. Because the
Effective Time may occur at a date later than the Storage Dimensions Special
Meeting or the Artecon Special Meeting, there can be no assurance that the
market price of Storage Dimensions Common Stock on the date of such meetings
will be indicative of its price at the Effective Time. The Reorganization
Agreement provides that the Effective Time will occur as soon as practicable
following the later to occur of the date when Storage Dimensions stockholder
approval and Artecon shareholder approval are obtained and the satisfaction or
waiver of the other conditions set forth in the Reorganization Agreement.
Stockholders of Storage Dimensions and shareholders of Artecon are urged to
obtain current market quotations for Storage Dimensions Common Stock. See
"MARKET PRICE INFORMATION" and "THE REORGANIZATION AGREEMENT -- Terms of the
Merger."
 
     NONREALIZATION OF SYNERGIES. The Merger involves the integration of two
companies that have previously operated independently and will require
substantial effort from each company, including the coordination of their
research and development and sales and marketing efforts and integration of
their product lines and personnel. There can be no assurance that Storage
Dimensions and Artecon will be able to integrate their operations without
encountering difficulties or experiencing the loss of key Storage Dimensions or
Artecon personnel or that the benefits expected from such integration will be
realized. In addition, the diversion of the attention of management and any
difficulties encountered in the transition process (including the interruption
of, or a loss of momentum in, the combined company's activities, problems
associated with integration of management information and reporting systems, and
delays in implementation of consolidation plans) could also have an adverse
impact on the combined company's ability to realize anticipated synergies from
the Merger. See "-- Recommendation of the Storage Dimensions Board; Storage
Dimensions Reasons for the Merger" and "-- Recommendation of the Artecon Board;
Artecon Reasons for the Merger."
 
                                       23
<PAGE>   39
 
     INCURRENCE OF SIGNIFICANT TRANSACTION CHARGES; DILUTIVE EFFECT TO
STOCKHOLDERS. The parties expect to incur costs estimated to be an aggregate of
approximately $5.1 million primarily for investment banking, legal and
accounting fees incurred in connection with the Merger and other costs
associated with combining the operations of the two companies, including
restructuring costs. These costs will be recorded by Artecon as part of the
purchase price at the time the Merger is consummated. Additional unanticipated
expenses may be incurred relating to the integration of the businesses of
Storage Dimensions and Artecon. There can be no assurance that combining the
businesses of Storage Dimensions and Artecon, even if achieved in an efficient
and effective manner, will result in combined results of operations and
financial condition superior to what would have been achieved by either company
independently. In accordance with purchase accounting rules, the historical book
values of the assets and liabilities of Storage Dimensions will be adjusted to
their fair values. The costs incurred to complete the Merger plus the excess of
the fair value of the consideration paid over the adjusted fair values of the
assets and liabilities of Storage Dimensions acquired will be recorded by
Artecon as goodwill which will be amortized over approximately 7 years. In
addition, the issuance of Storage Dimensions Common Stock in connection with the
Merger could reduce the market price of Storage Dimensions' Common Stock unless
revenue growth or cost savings and other business synergies sufficient to offset
the effect of such issuance can be achieved. Finally, as a result of the Merger,
any given Storage Dimensions stockholder's percentage ownership of Storage
Dimensions capital stock prior to the Merger will decrease substantially and the
percentage ownership of all pre-Merger Storage Dimensions stockholders will
decrease from 100% of the outstanding capital stock of Storage Dimensions
immediately prior to the Merger to approximately 37.5% of the outstanding
capital stock of Storage Dimensions immediately following the Merger.
 
     EFFECT OF MERGER ON CUSTOMERS AND PARTNERS. Certain of Storage Dimensions'
and Artecon's existing customers or strategic partners may view themselves as
competitors of the other. As a consequence, each company's relationship with
these customers or strategic partners could be adversely affected during the
pendency of the Merger and after its completion.
 
     VOLATILITY OF STOCK PRICES, ABSENCE OF PUBLIC MARKET FOR PREFERRED
STOCK. The market price of the Storage Dimensions Common Stock has been, and is
expected to continue to be, volatile. This volatility may result from a number
of factors, including fluctuations in the combined company's quarterly revenues
and net income, announcements of products by the combined company or its
competitors, and conditions in the network storage system market. In addition,
in the event that the Merger is not consummated, Storage Dimensions' stock price
may be adversely affected. Also, the stock market has experienced and continues
to experience extreme price and volume fluctuations which have affected the
market prices of securities, particularly those of technology companies, and
which often have been unrelated to the operating performance of the companies.
These broad market fluctuations, as well as general economic and political
conditions, may adversely affect the market price of the combined company's
Common Stock in future periods. In addition, following the Merger, Storage
Dimensions' Preferred Stock will not be publicly traded. As a result, there will
be no market for such stock and it is not expected that an active trading market
will ever develop for such shares.
 
     CERTAIN TERMS OF THE REORGANIZATION AGREEMENT. The Reorganization Agreement
does not provide that the representations and warranties of either party must be
true and correct as of the closing of the Merger. As a result, neither party has
the right to terminate the Reorganization Agreement if, before closing, the
other party experiences a material adverse change in its business, financial
condition or results of operations.
 
     EFFECT OF CERTAIN TERMS OF CHARTER DOCUMENTS AND DELAWARE ANTI-TAKEOVER
LAW. Certain provisions of Storage Dimensions' Certificate of Incorporation, as
amended, and Bylaws, as amended, the DGCL and Storage Dimensions'
indemnification agreements with certain officers and directors of Storage
Dimensions may be deemed to have an anti-takeover effect. Such provisions may
delay, defer or prevent a tender offer or takeover attempt that a stockholder
might consider to be in that stockholder's best interests, including attempts
that might result in a premium over the market price for the shares held by such
stockholder.
 
     The Storage Dimensions Board may issue additional shares of Storage
Dimensions Common Stock or establish one or more classes or series of Storage
Dimensions Preferred Stock, having the number of shares
 
                                       24
<PAGE>   40
 
(up to 10,000,000), designations, relative voting rights, dividend rates,
liquidation and other rights, preferences and limitations as determined by the
Storage Dimensions Board without stockholder approval. Storage Dimensions'
Certificate of Incorporation, as amended, and Bylaws, as amended, contain a
number of provisions that could impede a takeover or change in control of
Storage Dimensions, including but not limited to the elimination of
stockholders' ability to take action by written consent and a fair price
requirement. In addition, upon approval of the Certificate of Amendment by the
Storage Dimensions stockholders, the Storage Dimensions Certificate of
Incorporation (i) will provide for a classified Board of Directors, (ii) will
eliminate the ability of stockholders to remove a director from office without
cause except, until the third annual meeting of the stockholders of Storage
Dimensions following the Merger, by the affirmative vote of at least 80% of the
outstanding voting stock of Storage Dimensions and by the affirmative vote of at
least 66 2/3% of the outstanding voting stock of Storage Dimensions thereafter,
(iii) will designate a new Series A Preferred Stock (the "Series A Stock")
consisting of 2,494,159 shares and (iv) will change the name of Storage
Dimensions to "Artecon, Inc."
 
     At the Effective Time of the Merger, all of such shares of Storage
Dimensions Preferred Stock will be issued to holders of the Sauey Preferred in
exchange for the 2,494,159 shares of Sauey Preferred held by such persons. Each
share of Storage Dimensions Preferred Stock will be convertible, at the option
of the holder, at any time after January 1, 1999 into such number of shares of
Storage Dimensions Common Stock as is determined in accordance with the
conversion ratio prescribed in the Certificate of Amendment. Each share of
Storage Dimensions Preferred Stock will be converted automatically into shares
of Storage Dimensions Common Stock, as prescribed in the Certificate of
Amendment, on the earlier of the close of business on the day on which the
Storage Dimensions Board approves such conversion or when the 20-day average
closing price of Storage Dimensions Common Stock equals or exceeds $9.00 per
share. The maximum number of shares of Storage Dimensions Common Stock issuable
upon conversion of the Storage Dimensions Preferred Stock being issued in the
Merger is approximately 831,000. In the event of any liquidation, dissolution or
winding up of Storage Dimensions, the holders of the Storage Dimensions
Preferred Stock are entitled to a liquidation preference of $2.00 per share plus
all accrued, accumulated or declared but unpaid dividends on each share of
Storage Dimensions Preferred Stock held by such holders. The shares of Storage
Dimensions Preferred Stock will be voted together with the Storage Dimensions
Common Stock as a single class, and the holders of each share of Storage
Dimensions Preferred Stock will be entitled to the number of votes equal to the
number of shares of Storage Dimensions Common Stock into which such shares of
Storage Dimensions Preferred Stock could be converted on the record date for the
vote. Assuming the conversion of the Storage Dimensions Preferred Stock into the
maximum number of shares of Storage Dimensions Common Stock, holders of the
Sauey Preferred will hold approximately 27% of the outstanding voting stock of
Storage Dimensions immediately following the Merger (which percentage includes
all shares of Storage Dimensions Common Stock held by such holders), giving
effect to the conversion of the Storage Dimensions Preferred Stock being issued
in the Merger and the exercise of outstanding Storage Dimensions stock options
with an exercise price of less than $3.96875 per share.
 
     In addition, Storage Dimensions is subject to the anti-takeover provisions
of Section 203 of the DGCL. In general, the statute prohibits a publicly-held
Delaware corporation from engaging in a "business combination" with an
"interested stockholder" for a period of three years after the date of the
transaction in which the person became an interested stockholder.
 
     Each of the foregoing provisions gives the Storage Dimensions Board, acting
without stockholder approval, the ability to prevent, or render more difficult
or costly, the completion of a takeover transaction that stockholders might view
as being in their best interests. See "DESCRIPTION OF CAPITAL STOCK --
Description of Storage Dimensions Capital Stock -- Effect of Certain Terms of
Charter Documents and Delaware Anti-Takeover Law" and "COMPARISON OF RIGHTS OF
STORAGE DIMENSIONS STOCKHOLDERS AND ARTECON SHAREHOLDERS -- Stockholder Approval
of Certain Business Combinations."

RISKS RELATED TO THE BUSINESSES OF STORAGE DIMENSIONS AND ARTECON
 
     HISTORY OF OPERATING LOSSES; POTENTIAL FLUCTUATIONS IN QUARTERLY
RESULTS. While Storage Dimensions generated net income in 1996, it incurred
losses in 1993, 1994, 1995 and 1997. Artecon has similarly incurred losses in
prior periods. Storage Dimensions currently expects its revenues for the fiscal
quarter ending March 31, 1998 to be significantly less than its results of
operations for the fourth quarter of 1997 and for the first quarter of 1997.
Storage Dimensions attributes the decline to a combination of uncertainty in the
marketplace resulting from Storage Dimensions' announcement of the Merger in
late 1997 and continued sales force productivity issues. Artecon currently
expects its revenues for the fiscal quarter ending March 31, 1998 to be
significantly less than its results of operations for the quarter ended December
31, 1997. Artecon attributes the decline primarily to post-holiday seasonal
sales declines and uncertainty in the marketplace resulting from the
announcement of the Merger in late 1997. There can be no assurance that the
combined company will be profitable on a quarterly or annual basis.
 
     Storage Dimensions' and Artecon's quarterly operating results have in the
past varied and may in the future vary significantly depending on a number of
factors, including: the level of competition; the size, timing, cancellation or
rescheduling of significant orders; product configuration and mix; market
acceptance of new products and product enhancements; new product announcements
or introductions by competitors; deferrals of customer orders in anticipation of
new products or product enhancements; changes in pricing by the combined company
or its competitors; the impact of price protection measures and return
privileges granted by the combined company to its distributors and VARs; the
ability of the combined company to develop, introduce and market new products
and product enhancements on a timely basis; hardware component costs and
availability, particularly with respect to hardware components obtained from
sole sources; hardware supply constraints; the combined company's success in
expanding its sales and marketing programs; technological changes in the network
storage system market, in particular the PC-LAN and UNIX storage system markets;
the mix of sales among the combined company's sales channels; levels of
expenditures on research and development; changes in the combined company's
strategy; personnel changes; and general economic trends and other factors.
 
     Sales for any future quarter are not predictable with any significant
degree of certainty. Storage Dimensions and Artecon generally operate with
limited order backlog because their products typically are shipped shortly after
orders are received. As a result, sales in any quarter are generally dependent
on orders booked and shipped in that quarter. Sales are also difficult to
forecast because the PC-LAN and UNIX storage system markets are rapidly evolving
and Storage Dimensions' and Artecon's sales cycles vary substantially from
customer to customer. Each company's customers generally have the right to
cancel orders at any time and a limited right to return products for a refund.
The cancellation of orders already placed and the return of products could have
a material adverse effect on operating results in any quarter. Due to the
typical timing of customer orders, each company often ships products
representing a significant portion of its net sales for a quarter during the
last month of that quarter. Any significant deferral of these sales could have a
material adverse effect on the results of operations in any particular quarter.
To the extent that the combined company completes significant sales earlier than
expected, operating results for subsequent quarters may be adversely affected.
The combined company's expense levels will be 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.
 
     Over the past several years, Storage Dimensions has transitioned its focus
from desktop subsystem products to enterprise RAID products for use primarily in
PC-LAN network applications. As a result, Storage Dimensions has become
increasingly dependent on the market for these products and on its ability to
compete successfully in this market. Although Storage Dimensions has experienced
growth in its net sales of enterprise and OEM products in prior periods, Storage
Dimensions' net sales from its desktop products have declined during the same
periods. In recent periods, the level of net sales growth generated from Storage
Dimensions' enterprise and OEM products has not sustained a consistent
quarter-over-quarter growth in total net sales. There can be no assurance that
Storage Dimensions will experience sales growth with respect to its enterprise
and OEM products in future periods. Due to all of the foregoing factors,
period-to-period comparisons of its results of operations are not necessarily
meaningful and should not be relied upon as an indicator of future performance.
It is possible that in some future quarter the combined company's operating
results may be
 
                                       26
<PAGE>   42
 
below the expectations of public market analysts and investors. In such event,
the price of Storage Dimensions' Common Stock would likely be materially and
adversely affected.
 
     RELIANCE ON KEY CUSTOMERS AND INDIRECT DISTRIBUTION CHANNELS. Each of
Storage Dimensions and Artecon sells its products through a direct sales force
and through multi-tiered distribution channels. In 1997, Storage Dimensions' top
ten customers, of which six were distributors or VARs, accounted for
approximately 42% of Storage Dimensions' total net sales. In particular, The Sun
Financial Group, an end user, accounted for approximately 10% of Storage
Dimensions' 1997 total net sales. In 1996, Storage Dimensions' top ten
customers, of which six were distributors or VARs, accounted for approximately
50% of its total net sales, and Tech Data and Xerox accounted for approximately
8% and 13%, respectively, of Storage Dimensions' total net sales. In addition,
the following customers of Artecon accounted for approximately that percentage
of Artecon's total revenues set forth below during the periods indicated: UUNET
Technologies (13.5%) and GTE Government Systems (11.9%) for the nine-months
ended December 31, 1997; Tracor Enterprise Solution (26.6%) for the fiscal year
ended March 31, 1997; and GTE Government Systems (10.0%) for the fiscal year
ended March 31, 1996. No other customer accounted for more than 10% of Artecon's
total revenues during the nine-month period ended December 31, 1997, or during
the fiscal years ended March 31, 1997, 1996 or 1995. Storage Dimensions and
Artecon expect that a high percentage of the combined company's sales for the
foreseeable future will be through indirect channels and to a limited number of
customers. There can be no assurance that orders from existing customers will
continue at their historical levels, or that the combined company will be able
to obtain orders from new customers. Storage Dimensions and Artecon generally
have not entered into long-term volume purchase contracts with their customers,
and customers generally have certain rights to extend or to delay the shipment
of their orders. Storage Dimensions provides price protection to distributors
such that, if the company reduces the price of its products, distributors are
entitled to a credit for the difference between the new, reduced price and the
price previously paid for products held in the distributor's inventory at the
time of the price reduction. As a result, price reductions could have an
immediate material adverse effect on the combined company's results of
operations, depending upon distributor inventory levels at the time of the price
reduction. In 1995, 1996 and 1997, Storage Dimensions issued approximately
$550,000, $840,000, and $485,000, respectively, of credits in connection with
such price protection. The combined company's distributors and VARs may also
carry competing product lines and could reduce or discontinue sales of the
combined company's products, which could have a material adverse effect on the
combined company's operating results. Although Storage Dimensions and Artecon
believe that they provide adequate allowances for product returns, there can be
no assurance that actual returns will not exceed recorded allowances which could
have a material adverse effect on the combined company's operating results. In
addition, there can be no assurance that existing end-user customers will not
purchase their storage equipment from the manufacturer that provides their
network computing systems and, as a result, reduce or eliminate purchases from
the combined company. The loss of one or more of the combined company's current
customers, particularly a principal customer, or cancellation or rescheduling of
orders already placed, could materially and adversely affect the combined
company's business, operating results or financial condition. See "STORAGE
DIMENSIONS MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS" and "ARTECON MANAGEMENT'S DISCUSSION AND ANALYSIS OF
FINANCIAL CONDITION AND RESULTS OF OPERATIONS."
 
     DEPENDENCE ON NEW PRODUCTS; RAPID TECHNOLOGICAL CHANGE. The storage system
market is characterized by rapid technological change, changing customer needs,
frequent new product introductions and evolving industry standards. The
introduction of products embodying new technologies and increased storage
capacities by the combined company's competitors and the emergence of new
industry standards could render the combined company's products obsolete and
unmarketable. The combined company's future success will depend upon its ability
to develop and to introduce new products with increasing storage capabilities
(including new software releases and enhancements) on a timely basis that keep
pace with technological developments and emerging industry standards and address
the increasingly sophisticated needs of its customers. There can be no assurance
that the combined company will be successful in developing and marketing any
other products that respond to technological changes or evolving industry
standards, that the combined company will not experience difficulties that could
delay or prevent the successful development,
 
                                       27
<PAGE>   43
 
introduction and marketing of new products, or that its new products will
adequately meet the requirements of the marketplace and achieve market
acceptance. If the combined company is unable, for technological or other
reasons, to develop and introduce new products, in particular those for use with
Windows NT and UNIX systems, in a timely manner in response to changing market
conditions or customer requirements, the combined company's business, operating
results and financial condition will be materially and adversely affected.
 
     Storage system products like those offered by Storage Dimensions and
Artecon may contain undetected software errors or failures when first introduced
or as new versions are released. There can be no assurance that, despite
testing, errors will not be found in new products after commencement of
commercial shipments, resulting in a loss of or delay in market acceptance,
which could have a material adverse effect on the combined company's business,
operating results or financial condition. Each company's standard warranty
provides that if the system does not function to published specifications the
combined company will repair or replace the defective component without charge.
Although to date each of Storage Dimensions' and Artecon's suppliers of hardware
components have generally covered the warranty costs associated with such
components, there can be no assurance that such manufacturers will continue to
be willing or able to cover such costs, and their failure to do so would result
in such costs being borne by the combined company. There can be no assurance
that the combined company's warranty costs will not be significant in the
future. Significant warranty costs, particularly those that exceed reserves,
could have a material adverse effect on the combined company's business,
operating results or financial condition.
 
     Storage Dimensions' and Artecon's agreements with customers typically
contain provisions intended to limit exposure to potential product liability
claims. It is possible that the limitation of liability provisions contained in
Storage Dimensions' and Artecon's agreements may not be effective. Although
Storage Dimensions and Artecon have not received any product liability claims to
date, the sale and support of products by the combined company and the
incorporation of products from other companies may entail the risk of such
claims. A successful product liability claim against the combined company could
have a material adverse effect on the combined company's business, operating
results or financial condition.
 
     DEPENDENCE ON KEY PERSONNEL. The combined company's future performance will
depend in significant part upon the continued service of its senior management
and key sales and technical personnel. The combined company expects to provide
incentives such as salary, benefits and option grants (which are typically
subject to vesting over four years) to attract and retain qualified employees.
In recent periods, Storage Dimensions and Artecon have experienced difficulties
retaining existing and attracting and training new, skilled personnel. Any
inability to attract, train and retain skilled sales personnel in future periods
or the loss of the services of one or more of the combined company's officers or
other key employees could have a material adverse effect on the combined
company's business, operating results or financial condition. The combined
company's future success will also depend on its ability to attract and retain
highly qualified technical and management personnel. Competition for such
personnel is intense, and there can be no assurance that the combined company
can retain its key technical and management employees or that it can attract,
assimilate or retain other highly qualified technical and management personnel
in the future.
 
     DEPENDENCE ON GROWTH IN THE PC-LAN MARKET. Most of Storage Dimensions'
products address the PC-LAN market, in particular NetWare and Windows NT
applications. The combined company will likely continue to focus its development
and marketing efforts on storage system applications, including storage systems
for the UNIX market. The combined company's future financial performance will
depend in part on continued growth in the storage systems market. There can be
no assurance that the storage systems market will grow at rates currently
anticipated, or at all. If the storage systems market fails to grow or grows
more slowly than anticipated, or if storage systems based on emerging standards
other than standards adopted by the combined company become increasingly
accepted by the market, the combined company's business, operating results and
financial condition would be materially and adversely affected. During recent
years, segments of the computer industry have experienced significant economic
downturns characterized by decreased product demand, production over capacity,
price erosion, work slowdowns and layoffs. The combined company's operations may
in the future experience substantial fluctuations from period to period as a
consequence of such industry patterns, general economic conditions affecting the
timing of orders from major customers and
 
                                       28
<PAGE>   44
 
other factors affecting capital spending. There can be no assurance that such
factors will not have a material adverse effect on the combined company's
business, operating results or financial condition.
 
     COMPETITION. The storage system market is intensely competitive. Storage
Dimensions competes in the storage systems market and experiences the greatest
competition from traditional suppliers of storage systems, such as Compaq
Corporation ("Compaq"), Hewlett-Packard Company ("HP") and International
Business Machines Corporation ("IBM"), who market storage systems as part of
their complete computer systems. Storage Dimensions also competes against
independent storage system suppliers, including DEC Storage Works "DEC"), MTI
Technology ("MTI"), Procom Technology, Inc., Auspex Systems, Inc., Data General
Corporation, EMC Corporation, Network Appliance, Inc., Storage Computer, Inc.
and Symbios Logic, Inc. Such competitors could develop and market products that
address the storage systems market, and in particular Windows NT applications.
Many of Storage Dimensions' current and potential competitors have significantly
greater financial, technical, marketing, purchasing and other resources than
Storage Dimensions, and as a result, may be able to respond more quickly to new
or emerging technologies and changes in customer requirements, to devote greater
resources to the development, promotion and sale of products than can Storage
Dimensions, or to deliver competitive products at a lower end-user price.
Storage Dimensions also expects that competition will increase as a result of
industry consolidations. Current and potential competitors have established or
may establish cooperative relationships among themselves or with third parties
to increase the ability of their products to address the needs of Storage
Dimensions' prospective customers. Accordingly, it is possible that new
competitors or alliances among competitors may emerge and rapidly acquire
significant market share. Increased competition is likely to result in price
reductions, reduced operating margins and loss of market share, any of which
could have a material adverse effect on the combined company's business,
operating results or financial condition.
 
     Artecon has a number of competitors in various markets, including HP, Sun,
IBM, Silicon Graphics ("SGI"), Compaq, DEC, DG Clariion, MTI, and EMC
Corporation, many of which have substantially greater name recognition,
engineering, manufacturing and marketing capabilities, and greater financial and
personnel resources than Artecon. In particular, a number of Artecon's customers
are also competitors, including Sun and SGI. Artecon expects to experience
increased competition from established and emerging computer storage hardware
and management software companies, particularly HP, Sun, IBM, Compaq, DEC, and
EMC Corporation. In addition, increased competitive pressure could lead to
intensified price-based competition, which could have a material adverse effect
on Artecon's results of operations. There also has been, and may continue to be,
a willingness on the part of certain large competitors to reduce prices in order
to preserve or gain market share. Artecon believes that pricing pressures are
likely to continue as competitors develop more competitive product offerings.
 
     Storage Dimensions and Artecon believe that the principal competitive
factors affecting their markets include: fault-tolerant reliability,
performance, ease of use, scalability, configurability, price and customer
service and support. There can be no assurance that the combined company will be
able to successfully incorporate these factors into its products and to compete
against current or future competitors or that competitive pressures faced by the
combined company will not materially and adversely affect its business,
operating results or financial condition.
 
     DEPENDENCE ON LIMITED NUMBER OF SUPPLIERS OF HIGH QUALITY
COMPONENTS. Storage Dimensions relies upon a limited number of suppliers of
several key components utilized in the assembly of Storage Dimensions' products.
For example, Storage Dimensions purchases disk drives primarily from Seagate
Technology, Inc. ("Seagate"), DLT tape drives exclusively from Quantum
Corporation ("Quantum") and DGR (Dynamic Growth and Reconfiguration) RAID
controllers exclusively from American Megatrends, Inc. In addition, Artecon
relies upon a limited number of suppliers of several key components utilized in
the assembly of Artecon's products, including Seagate, IBM, Quantum, Infortrend,
Intel, CMD, Mylex and Sony. Storage Dimensions' and Artecon's reliance on its
suppliers involves several risks, including: an inadequate supply of required
components; price increases; late deliveries; and poor component quality. These
risks are particularly significant with respect to suppliers of disk drives
because, in order to meet product performance requirements, Storage Dimensions
and Artecon must obtain disk drives with extremely high quality and capacity. In
addition, there is currently a significant market demand for disk drives, tape
drives and RAID controllers, and from time to time Storage Dimensions and
Artecon may experience component shortages, selective supply
 
                                       29
<PAGE>   45
 
allocations and increased prices of such components. Although to date neither
Storage Dimensions nor Artecon has experienced shortages of such components,
there can be no assurance that the combined company will be able to obtain its
full requirements of such components in the future or that prices of such
components will not increase. In addition, there can be no assurance that
problems with respect to yield and quality of such components and timeliness of
deliveries will not occur. Disruption or termination of the supply of these
components could delay shipments of the combined company's products and could
have a material adverse effect on the combined company's business, operating
results or financial condition. Such delays could also damage relationships with
current and prospective customers.
 
     In the past, due to Storage Dimensions' quality requirements, Storage
Dimensions has experienced delays in the shipments of its new products
principally due to an inability to qualify component parts from disk drive
manufacturers and other suppliers, resulting in delay or loss of product sales.
Storage Dimensions has currently qualified disk drives manufactured by Seagate,
tape drives from Quantum, and RAID controllers from Mylex Corporation and
American Megatrends. Although these delays in the past have not had a material
adverse effect upon Storage Dimensions' business, operating results or financial
condition, there can be no assurance that in the future any such delays will not
have such a material adverse effect on the combined company.
 
     INTERNATIONAL OPERATIONS; CURRENCY FLUCTUATIONS. Artecon's international
sales represented approximately 12.5%, 14.0%, 25.2% and 18.6% of Artecon's total
revenues for the nine months ended December 31, 1997 and for the fiscal years
ended March 31, 1997, 1996 and 1995, respectively. Artecon currently has sales
offices in Japan, France, England and the Netherlands. Artecon and Storage
Dimensions believe that the continued growth and profitability of the combined
company will require expansion of international operations, particularly in
Europe and Japan. Accordingly, following the Merger, Storage Dimensions intends
to expand its international operations and enter additional international
markets, which will require significant management attention and financial
resources. In addition, the combined company's international operations are
subject to a variety of risks associated with conducting business
internationally, including fluctuations in currency exchange rates, longer
payment cycles, difficulties in staffing and managing international operations,
problems in collecting accounts receivable, seasonal reductions in business
activity during the summer months in Europe and certain other parts of the
world, increases in tariffs, duties, price controls or other restrictions on
foreign currencies, and trade barriers imposed by foreign countries, any of
which could have a material adverse effect on the combined company's business,
operating results and financial condition. In addition, the combined company has
only limited experience in developing localized versions of its products and
marketing and distributing its products internationally. There can be no
assurance that the combined company will be able to successfully localize,
market, sell and deliver its products internationally. The inability of the
combined company to expand its international operations successfully and in a
timely manner could have a material adverse effect on the combined company's
business, operating results and financial condition.
 
     A significant portion of Artecon's business is presently conducted in
currencies other than the U.S. dollar. Foreign currency transaction gains and
losses arising from normal business operations are credited to or charged
against earnings in the period incurred. As a result, fluctuations in the value
of the currencies in which the combined company conducts its business relative
to the U.S. dollar will continue to cause the currency transaction gains and
losses which Artecon has experienced in the past and continues to experience.
Due to the substantial volatility of currency exchange rates, among other
factors, the combined company cannot predict the effect of exchange rate
fluctuations upon future operating results. There can be no assurance that the
combined company will not experience currency losses in the future. Neither
Artecon or Storage Dimensions has previously undertaken hedging transactions to
cover its currency exposure but may hedge a portion of its currency exposure in
the future as management deems appropriate. See "ARTECON MANAGEMENT'S DISCUSSION
AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS."
 
     DEPENDENCE ON PROPRIETARY TECHNOLOGY. Storage Dimensions' and Artecon's
success depends significantly upon their respective proprietary technology.
Storage Dimensions and Artecon currently rely on a combination of patent,
copyright and trademark laws, trade secrets, confidentiality agreements and
contractual provisions to protect their proprietary rights and seek to protect
their respective software, documentation and other written materials under trade
secret and copyright laws, which afford only limited protection. Storage
 
                                       30
<PAGE>   46
 
Dimensions has registered its Storage Dimensions and LANStor trademarks and will
continue to evaluate the registration of additional trademarks as appropriate.
Storage Dimensions and Artecon have registered numerous trademarks and will
continue to evaluate the registration of additional trademarks as appropriate.
Storage Dimensions and Artecon generally enter into confidentiality agreements
with their employees and with key vendors and suppliers. Storage Dimensions
currently has one U.S. patent application pending associated with the
object-oriented layered architecture of its RAIDFlex array management software.
As of December 31, 1997, Artecon had been issued a total of seven U.S. patents
covering certain elements of its products. There can be no assurance that issued
patents will provide a meaningful competitive barrier or that any pending
patents at either company will ever be issued, that the combined company will
develop proprietary products or technologies that are patentable, that any
patent issued in the future will provide the combined company with any
competitive advantages or will not be challenged by third parties, or that the
patents of others will not have a material adverse effect on the combined
company's ability to do business. Storage Dimensions and Artecon believe that
the rapidly changing technology in the computer storage industry makes future
success dependent more on the technical competence and creative skills of its
personnel than on any patents it may be able to obtain.
 
     There has also been substantial litigation in the computer industry
regarding intellectual property rights, and litigation may be necessary to
protect the combined company's proprietary technology. Storage Dimensions and
Artecon have from time to time received claims that they are infringing third
parties' intellectual property rights, and there can be no assurance that third
parties will not in the future claim infringement by the combined company with
respect to current or future products, trademarks or other proprietary rights.
Storage Dimensions and Artecon expect that companies in the storage system
market will increasingly be subject to infringement claims as the number of
products and competitors in the combined company's target markets grows. Any
such claims or litigation may be time-consuming and costly, cause product
shipment delays, require the combined company to redesign its products or
require the combined company to enter into royalty or licensing agreements, any
of which could have a material adverse effect on the combined company's
business, operating results or financial condition. Despite the combined
company's efforts to protect its proprietary rights, unauthorized parties may
attempt to copy aspects of the combined company's products or to obtain and use
information that Storage Dimensions regards as proprietary. For example, in
February 1998, Artecon filed a suit against certain former employees alleging,
among other things, trade secret misappropriation. In addition, the laws of some
foreign countries do not protect proprietary rights to as great an extent as do
the laws of the United States. There can be no assurance that the combined
company's means of protecting its proprietary rights will be adequate or that
the combined company's competitors will not independently develop similar
technology, duplicate the combined company's products or design around patents
issued to the combined company or other intellectual property rights of the
combined company. See "BUSINESS OF ARTECON -- Legal Proceedings."
 
     EFFECT ON FUTURE STOCK SALES. An aggregate of approximately 4,500,623
shares of Storage Dimensions Common Stock beneficially owned by Capital Partners
and Maxtor Corporation have certain registration rights, including the right to
require registration of their shares under certain circumstances and subject to
certain conditions. The sale of a significant number of the foregoing shares at
one time pursuant to these registration rights may cause a reduction in the
market price of the Storage Dimensions Common Stock. See "DESCRIPTION OF STORAGE
DIMENSIONS CAPITAL STOCK -- Registration Rights."
 
     YEAR 2000 COMPLIANCE. Many currently installed computer systems and
software products are coded to accept only two digit entries in the date code
field. Beginning in the year 2000, these date code fields will need to accept
four digit entries to distinguish 21st century dates from 20th century dates. As
a result, in less than two years, computer systems and/or software used by many
companies may need to be upgraded to comply with such "Year 2000" requirements.
Significant uncertainty exists in the software industry concerning the potential
effects associated with such compliance. The cost of making the combined
company's products Year 2000 compliant is not expected to be material.
 
     Storage Dimensions believes that the purchasing patterns of customers and
potential customers may be affected by the Year 2000 issues in a variety of
ways. Many companies are expending significant resources to correct or patch
their current software systems for Year 2000 compliance. These expenditures may
result in reduced funds available to purchase products such as those offered by
the combined company. Conversely,
                                       31
<PAGE>   47
 
Year 2000 issues may cause other companies to accelerate purchases, thereby
causing an increase in short-term demand and a consequent decrease in long-term
demand for products. Additionally, Year 2000 issues could cause a significant
number of companies, including current customers, to reevaluate their current
information system needs, and as a result consider switching to other systems or
suppliers. Any of the foregoing could result in a material adverse effect on the
combined company's business, operating results and financial condition.

                       STORAGE DIMENSIONS SPECIAL MEETING
 
     At the Storage Dimensions Special Meeting, the Storage Dimensions
stockholders will consider and vote upon the approval of the Business
Combination Proposal, the Certificate of Incorporation Amendments, the Stock
Plan Amendments and such other matters as may properly come before the Storage
Dimensions Special Meeting or any adjournments or postponements thereof.
 
     THE STORAGE DIMENSIONS BOARD HAS UNANIMOUSLY APPROVED THE BUSINESS
COMBINATION PROPOSAL, THE CERTIFICATE OF INCORPORATION AMENDMENTS AND STOCK PLAN
AMENDMENTS AND UNANIMOUSLY RECOMMENDS THAT STORAGE DIMENSIONS STOCKHOLDERS VOTE
FOR THE BUSINESS COMBINATION PROPOSAL, THE CERTIFICATE OF INCORPORATION
AMENDMENTS AND STOCK PLAN AMENDMENTS. SEE "THE MERGER -- BACKGROUND OF THE
MERGER", "-- RECOMMENDATION OF THE STORAGE DIMENSIONS BOARD; STORAGE DIMENSIONS
REASONS FOR THE MERGER" AND "ADDITIONAL MATTERS FOR CONSIDERATION BY STORAGE
DIMENSIONS STOCKHOLDERS."
 
  Record Date
 
     The Storage Dimensions Board has fixed the close of business on February
23, 1998 as the Storage Dimensions Record Date for determining holders entitled
to notice of and to vote at the Storage Dimensions Special Meeting.
 
  Quorum
 
     The presence in person or by properly executed proxy of holders of a
majority of the issued and outstanding shares of Storage Dimensions Common Stock
is necessary to constitute a quorum at the Storage Dimensions Special Meeting.
Abstentions and broker non-votes will each be included in determining whether a
quorum is present.
 
  Required Votes
 
     Approval of the Business Combination Proposal and the Certificate of
Incorporation Amendments requires the affirmative vote of a majority of the
outstanding shares of Storage Dimensions Common Stock. Accordingly, abstentions
and broker non-votes are equivalent to negative votes for purposes of approving
the Business Combination Proposal and the Certificate of Incorporation
Amendments. The effectiveness of the Certificate of Incorporation Amendments is
subject to the approval of the Business Combination Proposal. Notwithstanding
any indication to the contrary, a vote against the Business Combination Proposal
will constitute a vote against the Certificate of Incorporation Amendments. In
addition, Proposals 2 and 3 are mutually dependent. That is, a vote against
Proposal 2 will constitute a vote against Proposal 3, and a vote against
Proposal 3 will constitute a vote against Proposal 2. Approval of the Stock Plan
Amendments will
 
                                       33
<PAGE>   49
 
require the affirmative vote of the holders of a majority of the shares of
Storage Dimensions Common Stock present in person or represented by proxy at the
Storage Dimensions Special Meeting and voting with respect to the Stock Plan
Amendments. Abstentions are equivalent to negative votes for purposes of
approving the Stock Plan Amendments. Broker non-votes will not be counted in
determining whether the Stock Plan Amendments have been approved.
 
  Voting Rights; Proxies
 
     As of the Storage Dimensions Record Date, there were 8,022,430 shares of
Storage Dimensions Common Stock issued and outstanding, each of which entitles
the holder thereof to one vote. All shares of Storage Dimensions Common Stock
represented by properly executed proxies will, unless such proxies have been
previously revoked, be voted in accordance with the instructions indicated in
such proxies.
 
     IF NO INSTRUCTIONS ARE INDICATED, SUCH SHARES OF STORAGE DIMENSIONS COMMON
STOCK WILL BE VOTED IN FAVOR OF APPROVAL OF THE BUSINESS COMBINATION PROPOSAL,
THE CERTIFICATE OF INCORPORATION AMENDMENTS AND STOCK PLAN AMENDMENTS. Storage
Dimensions does not know of any matters other than as described in the
accompanying Notice of the Storage Dimensions Special Meeting that are to come
before the Storage Dimensions Special Meeting. If any other matter or matters
are properly presented for action at the Storage Dimensions Special Meeting, the
persons named in the enclosed form of proxy and acting thereunder will have the
discretion to vote on such matters in accordance with their best judgment,
unless such authorization is withheld. A Storage Dimensions stockholder giving a
proxy pursuant to this proxy solicitation may revoke it at any time before it is
exercised by giving a subsequent proxy, delivering to the Secretary of Storage
Dimensions at the address of Storage Dimensions set forth elsewhere in this
Joint Proxy Statement/Prospectus a written notice of revocation prior to the
voting of the proxy at the Storage Dimensions Special Meeting, or attending the
Storage Dimensions Special Meeting and informing the Secretary of Storage
Dimensions in writing that such stockholder wishes to vote his or her shares in
person. However, mere attendance at the Storage Dimensions Special Meeting will
not in and of itself have the effect of revoking the proxy. Notwithstanding the
foregoing, the holders of a majority of the outstanding shares of Common Stock
of Storage Dimensions and the holders of a majority of the outstanding shares of
Artecon Common Stock and Artecon Preferred Stock have agreed to vote in favor of
the Merger and the Certificate of Incorporation Amendments and not to change
their vote prior to the holding of the Storage Dimensions Special Meeting and
the Artecon Special Meeting. See "OTHER AGREEMENTS -- Artecon Voting Agreements"
and "-- Storage Dimensions Voting Agreements."
 
     Votes cast by proxy or in person at the Storage Dimensions Special Meeting
will be tabulated by the election inspectors appointed for the meeting and such
inspectors will determine whether or not a quorum is present. The election
inspectors will treat abstentions as shares that are present and entitled to
vote for purposes of determining the presence of a quorum. If a broker indicates
on the proxy that it does not have discretionary authority as to certain shares
to vote on a particular matter, those shares will be treated as present for
purposes of determining whether or not a quorum is present, but will not be
considered as present and entitled to vote with respect to that matter.
 
  Solicitation of Proxies
 
     The expenses of the solicitations of proxies for the Storage Dimensions
Special Meeting will be borne by Storage Dimensions. In addition to solicitation
by mail, proxies may be solicited by directors, officers and employees of
Storage Dimensions in person or by telephone, telegram or other means of
communication. These persons will receive no additional compensation for
solicitation of proxies, but may be reimbursed for reasonable out-of-pocket
expenses in connection with such solicitation. Arrangements will also be made by
Storage Dimensions with custodians, nominees and fiduciaries for forwarding of
proxy solicitation materials to beneficial owners of shares held of record by
such custodians, nominees and fiduciaries, and Storage Dimensions will reimburse
such custodians, nominees and fiduciaries for reasonable expenses incurred in
connection therewith.

                                   THE MERGER
 
     This section of the Joint Proxy Statement/Prospectus, as well as the next
two sections of the Joint Proxy Statement/Prospectus entitled "The
Reorganization Agreement" and "Other Agreements," describe certain aspects of
the proposed Merger. To the extent that the following descriptions relate to the
Reorganization Agreement, or the other agreements described under "Other
Agreements," they do not purport to be complete and are qualified in their
entirety by reference to the Reorganization Agreement, which is attached as
Annex A to this Joint Proxy Statement/Prospectus, to the Certificate of
Amendment of the Storage Dimensions Certificate of Incorporation, which is
attached as Annex B to this Joint Proxy Statement/Prospectus, to the Voting
Agreements, which are attached as Annexes E and F to this Joint Proxy
Statement/Prospectus, and to each of the other agreements described herein which
are filed as exhibits to the Registration Statement of which this Joint Proxy
Statement/Prospectus is a part, all of which documents are incorporated herein
by reference. All stockholders are urged to read the Reorganization Agreement,
the Certificate of Amendment, the Voting Agreements and such other agreements in
their entirety.
 
GENERAL
 
     The Reorganization Agreement provides for the merger of Merger Sub with and
into Artecon. As a result of the Merger, Merger Sub will cease to exist, Artecon
will become a wholly-owned subsidiary of Storage Dimensions, and the former
shareholders of Artecon will become stockholders of Storage Dimensions. The
Reorganization Agreement provides that the Merger will be consummated if the
required approvals of the Artecon shareholders and the Storage Dimensions
stockholders are obtained and all other conditions to the Merger are satisfied
or waived.
 
     In the Merger, Storage Dimensions will issue an aggregate of approximately
13,120,000 million shares of Storage Dimensions Common Stock to the Artecon
shareholders. Such shares would have a value of approximately $52,480,000, based
upon the closing price of Storage Dimensions Common Stock as reported on the
Nasdaq National Market on February 23, 1998. In addition, Storage Dimensions
will issue an aggregate of 2,494,159 shares of Storage Dimensions Series A
Preferred Stock to certain Artecon shareholders, which shares will not be
publicly traded. Immediately following the Business Combination, the former
holders of Artecon capital stock will hold approximately 62.5% of the
outstanding capital stock of Storage Dimensions and the current holders of
Storage Dimensions Common Stock will hold approximately 37.5% of the outstanding
capital stock of Storage Dimensions, in each case giving effect to the
conversion of the Storage Dimensions Series A Preferred Stock being issued in
the Merger and the exercise of outstanding Storage Dimensions stock options with
an exercise price of less than $3.96875 per share. While the percentage of
outstanding capital stock of Storage Dimensions to be held by former holders of
Artecon Common Stock and current holders of Storage Dimensions Common Stock
following the Merger is fixed, the exact number of shares of Storage Dimensions
Common Stock issuable to the former Artecon shareholders (but not shares of
Storage Dimensions Preferred Stock) is subject to modest change based upon
changes in the number of outstanding shares of Storage Dimensions Common Stock
and Artecon Common Stock prior to the Merger. Based upon the number of shares of
each company outstanding on February 23, 1998, approximately 2.16 shares of
Storage Dimensions Common Stock would be issued for each share of Artecon Common
Stock in the Merger. While dollar fluctuations in the market price of Storage
Dimensions Common Stock will not affect the Exchange Ratio, they would change
the aggregate value of shares of Storage Dimensions Common Stock issued in the
Merger.
 
     More specifically the exact number of shares of Storage Dimensions Common
Stock into which each share of Artecon Common Stock will be converted will be
determined as of the Effective Time (as defined below) as follows: the Exchange
Ratio will be a fraction the numerator of which is the number of Merger Shares
(as defined below) and the denominator of which is the number of Artecon Shares
(as defined below). "Merger Shares" shall mean the shares of Storage Dimensions
Common Stock to be issued to holders of Artecon Common Stock in the Merger and
shall be equal to the product of (A) the Applicable Multiple times (B) the sum
of (x) the number of shares of Storage Dimensions Common Stock outstanding
immediately prior to the Effective Time plus (y) the maximum number of shares of
Storage Dimensions Common Stock issuable upon exercise of any options to
purchase Storage Dimensions Common Stock (without regard to

shall mean the sum of (A) the number of shares of Artecon Common Stock
outstanding immediately prior to the Effective Time plus (B) the maximum number
of shares of Artecon Common Stock underlying any instruments convertible into or
exchangeable for Artecon Common Stock (without regard to vesting) outstanding
immediately prior to the Effective Time, including shares of Artecon Preferred
Stock other than the 2,494,159 shares of Artecon Preferred Stock held by W. R.
Sauey and certain of his affiliates. Such shares of Artecon Preferred Stock held
by W.R. Sauey and such affiliates (the "Sauey Preferred") will be converted into
2,494,159 shares of Storage Dimensions Preferred Stock pursuant to the Merger.
Although the Applicable Multiple is fixed, the Exchange Ratio is subject to
modest change based upon changes in the number of shares of Storage Dimensions
Common Stock and Artecon Common Stock outstanding immediately prior to the
Effective Time.
 
     In addition, each share of Artecon Preferred Stock outstanding at the
Effective Time (other than Dissenting Shares) will be converted into the right
to receive one share of Storage Dimensions Preferred Stock. All holders of
Artecon Preferred Stock, other than the Sauey Preferred, have agreed to convert
such Artecon Preferred Stock into shares of Artecon Common Stock prior to the
Effective Time, which shares will then be converted into Storage Dimensions
Common Stock pursuant to the Merger.
 
EFFECTIVE TIME
 
     The Merger will become effective (the "Effective Time") upon the filing and
acceptance of a certificate of merger with the Secretary of State of the State
of California (the "Certificate of Merger"). The filing of the Certificate of
Merger will occur as soon as practicable after the latest to occur of the
approval of the Merger by the Artecon shareholders or the Storage Dimensions
stockholders, subject to the satisfaction or waiver of the other conditions to
the consummation of the Merger. If the requisite approvals of stockholders of
Storage Dimensions and shareholders of Artecon are received and all other
conditions to the Merger are satisfied or waived, the Merger is anticipated to
close on or about March 31, 1998.
 
     The Reorganization Agreement may be terminated under certain circumstances
by any party if the Merger shall not have been consummated on or before May 31,
1998. The Reorganization Agreement may also be terminated under certain other
circumstances. See "THE REORGANIZATION AGREEMENT -- Conditions to the Merger"
and "-- Termination of the Reorganization Agreement."

customary form, together with instructions for effecting the surrender of
Artecon stock certificates in exchange for certificates representing Storage
Dimensions Common Stock or Preferred Stock. Upon surrender of an Artecon stock

corporate purposes, other than the payment of dividends and distributions, to
evidence ownership of the number of full shares of Storage Dimensions Common
Stock or Storage Dimensions Preferred Stock into which such shares of Artecon

BACKGROUND OF THE MERGER
 
  Storage Dimensions
 
     In late 1996, the Storage Dimensions Board began a thorough review of the
strategic alternatives available to expand its business. Alternatives considered
included combining with another industry participant, selling the business to a
larger company and effecting an initial public offering of Storage Dimensions
Common Stock in order to reduce its debt burden and finance expanding
operations. In late 1996 and early 1997, Storage Dimensions contacted potential
business combination/acquisition candidates, including Artecon. Storage
Dimensions also began its initial public offering process. As the business
combination/ acquisition activities did not look as promising as effecting an
initial public offering, Storage Dimensions elected to discontinue the
combination/acquisition activities and focus its efforts instead on completing a
public offering. In March 1997, Storage Dimensions completed its initial public
offering.
 
     Beginning in mid-1997, the Storage Dimensions Board again began to consider
the benefits of developing relationships with other participants in the
industry. It was anticipated that this could provide additional strength to
counter the growing competitiveness of the industry and the recent unfavorable
financial results of Storage Dimensions. In September 1997, Storage Dimensions
retained Salomon Smith Barney as its financial advisor to assist Storage
Dimensions in identifying potential strategic transaction partners. Storage
Dimensions began to hold discussions in the fall of 1997 with a third party, but
these discussions did not result in any definitive terms or an offer to enter
into a strategic combination with Storage Dimensions.
 
                                       40

  Artecon
 
     In February and March 1995, the Artecon Board and senior management of
Artecon began to discuss alternative strategies for the long-term growth of
Artecon. The alternatives discussed included an initial public offering of
Artecon's Common Stock, joint ventures and other strategic business
arrangements, including possible acquisitions of companies with complementary
products or market position. Due to market conditions at the time, the Artecon
Board determined that the best course of action would be to explore possible
business combinations with properly situated companies, to be followed by an
initial public offering, if then appropriate.
 
     At the end of 1995 and during 1996, the Artecon Board and senior management
of Artecon identified various companies that it considered to be potential
candidates to be approached for a possible business combination, including
Storage Dimensions and Falcon Systems, Inc. ("Falcon"). The Artecon Board
reviewed the business, financial condition and performance, prospects,
technology and product offerings of such candidates, focusing efforts on Storage
Dimensions and Falcon. In the summer of 1996, Artecon had discussions with
Falcon regarding a potential business combination, which discussions
subsequently were terminated. At various times between September 1996 and
January 1997, Artecon met informally with management of Storage Dimensions to
discuss a possible business combination. By January 1997, however, Storage
Dimensions was in the process of its initial public offering and both parties
felt it was in their best interests to terminate discussions.
 
     In August 1997, Artecon completed the acquisition of substantially all of
the assets and certain liabilities of Falcon (the "Falcon Acquisition"). The
Falcon Acquisition added new products and additional domestic sales offices and
sales personnel to Artecon's business operations. Through the Falcon
Acquisition, Artecon significantly expanded its customer and revenue base, and
expects to be able to take advantage of certain economies of scale through the
consolidation of the companies' business operations and customer service,
accounting and administrative functions.
 
  Contacts between the Parties
 
     In early November 1997, a telephone conference between the Storage
Dimensions Chairman of the Board and members of Artecon management was held at
which the potential benefits of a business combination of the two parties were
discussed. The parties agreed to continue to further explore a potential
business combination.
 
     On November 19, 1997, the Vice Chairman of the Board and Chief Executive
Officer of Storage Dimensions visited Artecon's facility in Carlsbad, California
and met with members of Artecon management. During these discussions, the
participants continued to evaluate the potential benefits of a business
combination and performed due diligence investigations of each other.
 
     On November 28, 1997, the Chairman and Vice Chairman of the Storage
Dimensions Board met with the Chairman of the Board and the Chief Executive
Officer of Artecon. The specific terms of a business combination, including
percentage ownership by each party were discussed at length. Both parties agreed
to hold further discussions to continue to negotiate specific terms. To
facilitate such discussions, a mutual confidentiality and nonsolicitation
agreement was signed by both parties on December 4, 1997.
 
     On December 8, 1997, representatives of Artecon visited Storage Dimensions
for the purpose of conducting their due diligence investigation of Storage
Dimensions and held several meetings with Storage Dimensions management.
 
     On December 11, 1997, Storage Dimensions management, representatives of its
auditors and Salomon Smith Barney visited Artecon to continue their due
diligence investigation of Artecon and held several meetings with members of
Artecon management.
 
     From December 15 through December 18, 1997, Storage Dimensions management
and its auditors continued to meet with Artecon management to continue their due
diligence review of Artecon.
 
     On December 19, 1997, Storage Dimensions held a meeting of its Board of
Directors at which the potential synergies of a business combination with
Artecon were reviewed. Members of Storage Dimensions
 
                                       41
<PAGE>   57
 
management reported on their financial review of Artecon. Storage Dimensions'
legal counsel was also present at this meeting and reviewed the progress of the
drafting of definitive merger documents, the terms thereof and due diligence
issues identified to date.
 
     Also on December 19, 1997, Artecon held a meeting of its Board of Directors
to review and discuss the proposed terms of the potential business combination
between Artecon and Storage Dimensions. Artecon's legal counsel reviewed the
terms of the proposed combination and due diligence issues disclosed in legal
counsel's review of Storage Dimensions' documents.
 
     On December 20, 1997, another Storage Dimensions Board meeting was held. At
this meeting, Salomon Smith Barney reviewed with the Board certain financial
aspects of the proposed transaction. Extensive discussions ensued concerning the
transaction and Storage Dimensions' strategic alternatives. Storage Dimensions'
legal counsel also participated in this meeting and reviewed with the Board
draft merger documents and due diligence issues.
 
     On December 22, 1997, another Storage Dimensions Board meeting was held. At
the meeting, Storage Dimensions' legal counsel reviewed the terms of the
proposed definitive merger and related documents and final due diligence issues.
Also at such meeting, Salomon Smith Barney rendered its opinion to the effect
that, as of such date and based upon and subject to certain matters stated in
such opinion, the Merger Consideration was fair, from a financial point of view,
to Storage Dimensions, and reviewed the financial analyses performed by Salomon
Smith Barney in connection with such opinion. After extensive discussion, the
Storage Dimensions Board unanimously approved the Merger and the Reorganization
Agreement.
 
     On December 22, 1997, the Artecon Board held another meeting at which
Artecon's legal counsel reviewed the terms of the proposed merger contained in
the definitive merger documents. In particular, the Artecon Board discussed with
legal counsel certain terms of the Reorganization Agreement, the Voting
Agreements and the proposed amendments to the Storage Dimensions Certificate of
Incorporation to be filed in connection with the Merger. Following full
discussion of the proposed merger, the Artecon Board unanimously approved the
Merger Proposal and the transactions contemplated thereby.
 
     On the same day, the Reorganization Agreement, Voting Agreements and
Affiliate Agreements were executed by the parties.
 
RECOMMENDATION OF THE STORAGE DIMENSIONS BOARD; STORAGE DIMENSIONS REASONS FOR
THE MERGER
 
     The Storage Dimensions Board has unanimously determined that the terms of
the Reorganization Agreement and the Merger are fair to, and in the best
interests of, the Storage Dimensions stockholders. Accordingly, the Storage
Dimensions Board has unanimously approved the Reorganization Agreement and
unanimously recommends that the Storage Dimensions stockholders vote FOR
approval of the Business Combination Proposal. In reaching its determination,
the Storage Dimensions Board consulted with Storage Dimensions' management, as
well as its legal counsel, accountants and financial advisor, and gave
significant consideration to a number of factors bearing on its decision. The
post-Merger ownership between Storage Dimensions stockholders and Artecon
shareholders was determined in arm's-length negotiation. The ownership
allocation ultimately agreed to by the Storage Dimensions Board was approved by
such Board based upon the Storage Dimensions Board's evaluation of a number of
factors including the amount of revenue contributed by each party in the Merger,
the amount of Earnings Before Income Taxes ("EBIT") contributed by each party in
the Merger, the historical gross margins of each party, relative balance sheet
contributions of each party and technology contributions by each party. The
following are the primary reasons the Storage Dimensions Board believes the
Merger will be beneficial to Storage Dimensions and its stockholders:
 
     - The belief that the Merger represents an opportunity to more rapidly
       increase sales revenue through further penetration of the existing
       customers of both organizations. In particular, the potential for
       expanded product offerings into the UNIX marketplace with existing
       Storage Dimensions customers and the penetration with Windows NT products
       into the existing Artecon customer base was considered.
 
                                       42
<PAGE>   58
 
     - The belief that the foreign sales capabilities of Artecon would give
       Storage Dimensions access to these markets far sooner and more
       economically than it would be able to achieve on its own.
 
     - The belief that Storage Dimensions has significant software expertise in
       the area of storage management (RAIDScape software) and clustered storage
       systems (SuperFlex 5500); and that Artecon has significant hardware
       design expertise (Lynx, Sphinx, AerReal).
 
     - The belief that the combined research and development staff will be more
       productive and allow a sharper focus on the key competencies of each
       company.
 
     - The belief that the combined purchasing power of the two companies could
       result in significant cost reductions for key components, particularly
       disk drives.
 
     - The belief that the efficiencies of combining operations and
       administrative functions would result in cost savings by eliminating
       certain fixed costs.
 
     - The belief that the larger market presence of the combined company would
       result in significant increases in marketing strength and presence and
       would improve the combined company's competitive posture in both industry
       segments.
 
     - The belief that the increased size of the combined company would enhance
       its ability to attract and retain skilled personnel, especially in the
       area of sales, operations, and research and development.
 
     - The belief that there is a significant potential enhancement of the
       strategic and market position of the combined company beyond that
       achievable by Storage Dimensions alone.
 
     In addition to the reasons set forth above, during the course of its
deliberations concerning the Merger, the Storage Dimensions Board consulted with
Storage Dimensions' legal counsel and financial advisors as well as Storage
Dimensions' management, and reviewed a number of other factors relevant to the
Merger, including:
 
     - Information concerning the business, assets, operations, properties,
       management, financial condition, operating results, competitive position
       and prospects of Storage Dimensions and Artecon.
 
     - Reports from its legal counsel on specific terms of the Reorganization
       Agreement, the Storage Dimensions Voting Agreements and the Certificate
       of Amendment;
 
     - The opinion of Salomon Smith Barney to the effect that, as of December
       22, 1997 and based upon and subject to certain matters stated in such
       opinion, the Merger Consideration was fair, from a financial point of
       view, to Storage Dimensions (See "-- Opinion of Financial Advisor to
       Storage Dimensions").
 
     The Storage Dimensions Board also considered a number of potentially
negative factors in its deliberations concerning the Merger, including:
 
     - The risk that the combined company might not be able to achieve revenues
       equal to the sum of the anticipated revenues of Storage Dimensions and
       Artecon as independent entities.
 
     - The risk that revenue might shrink if some significant customers reduce
       or terminate their purchase of Storage Dimensions and/or Artecon products
       because of uncertainties concerning the Merger.
 
     - The risk that the combined company might not achieve the expected revenue
       and operating synergies.
 
     - The adverse effects of one-time charges expected to be incurred in
       connection with the costs of the Merger and the subsequent integration of
       the companies, including write-offs for in-process research and
       development expenses of Storage Dimensions.
 
     - The potential adverse effects on the combined company's results of
       operations of amortizing the goodwill that would be recorded in
       connection with the Merger.
 
     - The risk that certain key employees or members of management of either
       Storage Dimensions or Artecon may decide not to continue employment with
       the combined company.
 
                                       43
<PAGE>   59
 
     - The risk that other benefits sought to be achieved by the Merger would
       not be obtained.
 
     After carefully considering the potentially negative factors set forth
above, the Storage Dimensions Board concluded that the potential benefits
attendant to the Merger outweighed such negative factors and determined that the
Merger is fair to and in the best interest of the Storage Dimensions
stockholders.
 
     The foregoing discussion of the information and positive and negative
factors considered by the Storage Dimensions Board in approving of the Business
Combination Proposal is not intended to be exhaustive, but includes the factors
considered by the Storage Dimensions Board to have been material in their
analysis of the Business Combination Proposal. In considering the Business
Combination Proposal, given the number and diversity of the potentially positive
and negative factors considered, the Storage Dimensions Board did not find it
practical or feasible to quantify or otherwise attempt to assign any relative or
specific values to any of the foregoing factors. In making their determination,
individual directors may have accorded different values to different factors.
 
RECOMMENDATION OF THE ARTECON BOARD; ARTECON REASONS FOR THE MERGER
 
     The Artecon Board has unanimously determined that the terms of the
Reorganization Agreement and the transactions contemplated thereby are fair to,
and in the best interests of, the Artecon shareholders. Accordingly, the Artecon
Board has unanimously approved the Merger Proposal and unanimously recommends
that the Artecon shareholders vote FOR approval of the Merger Proposal. The
Artecon Board believes that the Merger will result in greater value to Artecon's
shareholders than would otherwise be realized through continued growth of
Artecon as an independent entity.
 
     The following list includes some of the factors the Artecon Board
considered material in its evaluation of the Merger:
 
     - The belief that the Merger represents an opportunity to increase
       Artecon's product and services offerings and market penetration in a
       shorter period of time than the continued growth of Artecon as an
       independent entity.
 
     - The belief that the immediate increase in customer base of the combined
       company would provide Artecon with the size and breadth of product
       offerings necessary to enhance its market position within the UNIX and
       Windows NT markets.
 
     - The belief that the combined company would be able to include additional
       product enhancement in its Windows NT platforms, enabling it to meet the
       needs of customers who use Windows NT as well as UNIX platforms (i.e.,
       customers would be able to call one vendor to provide them with
       peripherals that operate on both the Windows NT and UNIX platforms).
 
     - The belief that Storage Dimensions' software products in development
       would add significant value and key differentiation in the marketplace
       (RAIDScape software and clustered storage systems software for Windows NT
       applications).
 
     - The belief that the larger revenue and asset base of the combined company
       would likely enhance the combined company's access to equity and debt
       capital.
 
     - The belief that the combined company would likely realize certain
       operating efficiencies as a result of the Merger, including in the areas
       of research and development and administration.
 
     - The belief that the increased size of the combined company would enhance
       its ability to attract and retain skilled personnel, especially in the
       area of sales, operations and research and development.
 
     - The liquidity for the Artecon shareholders that would result from the
       Merger.
 
     The Artecon Board also considered a number of potentially negative factors
concerning the Merger, including:
 
     - The risk that the combined company might not be able to achieve revenues
       equal to the sum of the anticipated revenues of Storage Dimensions and
       Artecon as independent entities.
 
                                       44
<PAGE>   60
 
     - The risk that the combined company might not realize the anticipated
       economies of scale or combined operating efficiencies.
 
     - The adverse effects of one-time charges expected to be incurred in
       connection with the costs of the Merger and the subsequent integration of
       the companies, including write-offs for in-process research and
       development expenses of Storage Dimensions.
 
     - The potential adverse effects on the combined company's results of
       operations of amortizing the goodwill that would be recorded in
       connection with the Merger.
 
     - The potential that certain key employees or members of management of
       either Storage Dimensions or Artecon may determine not to continue
       employment with the combined company.
 
     - The risk that other benefits sought to be achieved by the Merger would
       not be obtained.
 
     After carefully considering the potentially negative factors set forth
above, the Artecon Board concluded that the potential benefits attendant to the
Merger outweighed such negative factors and determined that the Merger is fair
to and in the best interest of the Artecon shareholders. On December 22, 1997,
the Artecon Board unanimously approved the Merger Proposal and recommended that
the Artecon shareholders vote in favor of the Merger Proposal.
 
     The foregoing discussion of the information and positive and negative
factors considered by the Artecon Board in approving the Merger Proposal is not
intended to be exhaustive, but includes the factors considered by the Artecon
Board to have been material in their analysis of the Merger Proposal. In
considering the Merger Proposal, given the number and diversity of the
potentially positive and negative factors considered, the Artecon Board did not
find it practical or feasible to quantify or otherwise attempt to assign any
relative or specific values to any of the foregoing factors. In making their
determination, individual directors may have accorded different values to
different factors.
 
OPINION OF FINANCIAL ADVISOR TO STORAGE DIMENSIONS
 
     Salomon Smith Barney was retained by Storage Dimensions to act as its
financial advisor in connection with the proposed Merger. On December 22, 1997,
at a meeting of the Board of Directors of Storage Dimensions held to evaluate
the proposed Merger, Salomon Smith Barney delivered an oral opinion (which
opinion was subsequently confirmed by delivery of a written opinion dated
December 22, 1997) to the Board of Directors of Storage Dimensions to the effect
that, as of the date of such opinion and based upon and subject to certain
matters stated therein, the Merger Consideration was fair, from a financial
point of view, to Storage Dimensions. Salomon Smith Barney's opinion does not
address the fairness of the Merger Consideration from a financial point of view
to the stockholders of Storage Dimensions since the stockholders of Storage
Dimensions will not be asked to convert their shares of Storage Dimensions
Common Stock in the Merger.
 
     In arriving at its opinion, Salomon Smith Barney reviewed the
Reorganization Agreement and held discussions with certain senior officers,
directors and other representatives and advisors of Storage Dimensions and
certain senior officers and other representatives and advisors of Artecon
concerning the businesses, operations and prospects of Storage Dimensions and
Artecon. Salomon Smith Barney examined certain publicly available business and
financial information relating to Storage Dimensions and certain available
business and financial information relating to Artecon as well as certain
financial forecasts and other information and data for Storage Dimensions and
Artecon which were provided to or otherwise discussed with Salomon Smith Barney
by the respective managements of Storage Dimensions and Artecon, including
information relating to certain strategic implications and operational benefits
anticipated to result from the Merger. Salomon Smith Barney reviewed the
financial terms of the Merger as set forth in the Reorganization Agreement in
relation to, among other things: current and historical market prices and
trading volumes of Storage Dimensions Common Stock; the historical and projected
earnings and other operating data of Storage Dimensions and Artecon; and the
capitalization and financial condition of Storage Dimensions and Artecon.
Salomon Smith Barney also considered, to the extent publicly available, the
financial terms of certain other similar transactions recently effected which
Salomon Smith Barney considered relevant in evaluating the Merger and analyzed
certain financial, stock market and other publicly available information
relating to the
 
                                       45
<PAGE>   61
 
businesses of other companies whose operations Salomon Smith Barney considered
relevant in evaluating those of Storage Dimensions and Artecon. Salomon Smith
Barney also evaluated the potential pro forma financial impact of the Merger on
Storage Dimensions. In addition to the foregoing, Salomon Smith Barney conducted
such other analyses and examinations and considered such other financial,
economic and market criteria as Salomon Smith Barney deemed appropriate in
arriving at its opinion. Salomon Smith Barney noted that its opinion was
necessarily based upon information available, and financial, stock market and
other conditions and circumstances existing and disclosed, to Salomon Smith
Barney as of the date of its opinion.
 
     In rendering its opinion, Salomon Smith Barney assumed and relied, without
independent verification, upon the accuracy and completeness of all financial
and other information and data publicly available or furnished to or otherwise
reviewed by or discussed with Salomon Smith Barney. With respect to financial
forecasts and other information and data provided to or otherwise reviewed by or
discussed with Salomon Smith Barney, the managements of Storage Dimensions and
Artecon advised Salomon Smith Barney that such forecasts and other information
and data were reasonably prepared on bases reflecting the best currently
available estimates and judgments of the respective managements of Storage
Dimensions and Artecon as to the future financial performance of Storage
Dimensions and Artecon and the strategic implications and operational benefits
(including the amount, timing and achievability thereof) anticipated to result
from the Merger. Salomon Smith Barney assumed, with the consent of the Board of
Directors of Storage Dimensions, that the Merger will be treated as a tax-free
reorganization for federal income tax purposes. Salomon Smith Barney also
assumed, with the consent of the Board of Directors of Storage Dimensions, that
the number of fully diluted shares of Storage Dimensions Common Stock
outstanding immediately prior to the Effective Time would not vary materially
from the number of fully diluted shares of Storage Dimensions Common Stock
outstanding as of December 22, 1997. The opinion of Salomon Smith Barney, as set
forth therein, relates to the relative values of Storage Dimensions and Artecon.
Salomon Smith Barney did not express any opinion as to what the value of the
Storage Dimensions Common Stock or Storage Dimensions Preferred Stock actually
will be when issued pursuant to the Merger, what the value of the Storage
Dimensions Common Stock will be upon conversion of the Storage Dimensions
Preferred Stock or the prices at which the Storage Dimensions Common Stock or
Storage Dimensions Preferred Stock will trade or otherwise be transferable
subsequent to the Merger. Salomon Smith Barney did not make and was not provided
with an independent evaluation or appraisal of the assets or liabilities
(contingent or otherwise) of Storage Dimensions or Artecon nor did Salomon Smith
Barney make any physical inspection of the properties or assets of Storage
Dimensions or Artecon. Salomon Smith Barney was not requested to consider, and
Salomon Smith Barney's opinion does not address, the relative merits of the
Merger as compared to any alternative business strategies that might exist for
Storage Dimensions or the effect of any other transaction in which Storage
Dimensions might engage. Although Salomon Smith Barney evaluated the Merger
Consideration from a financial point of view, Salomon Smith Barney was not asked
to and did not recommend the specific consideration payable in the Merger, which
was determined through negotiation between Storage Dimensions and Artecon. No
other limitations were imposed by Storage Dimensions on Salomon Smith Barney
with respect to the investigations made or procedures followed by Salomon Smith
Barney in rendering its opinion.
 
     THE FULL TEXT OF THE WRITTEN OPINION OF SALOMON SMITH BARNEY DATED DECEMBER
22, 1997, WHICH SETS FORTH THE ASSUMPTIONS MADE, MATTERS CONSIDERED AND
LIMITATIONS ON THE REVIEW UNDERTAKEN, IS ATTACHED HERETO AS ANNEX C AND SHOULD
BE READ CAREFULLY IN ITS ENTIRETY. THE OPINION OF SALOMON SMITH BARNEY IS
DIRECTED TO THE BOARD OF DIRECTORS OF STORAGE DIMENSIONS AND RELATES ONLY TO THE
FAIRNESS OF THE MERGER CONSIDERATION FROM A FINANCIAL POINT OF VIEW TO STORAGE
DIMENSIONS, DOES NOT ADDRESS ANY OTHER ASPECT OF THE MERGER OR RELATED
TRANSACTIONS AND DOES NOT CONSTITUTE A RECOMMENDATION TO ANY STOCKHOLDER AS TO
HOW SUCH STOCKHOLDER SHOULD VOTE AT THE STORAGE DIMENSIONS SPECIAL MEETING. THE
SUMMARY OF THE OPINION OF SALOMON SMITH BARNEY SET FORTH IN THIS JOINT PROXY
STATEMENT/PROSPECTUS IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL TEXT
OF SUCH OPINION.
 
     In preparing its opinion, Salomon Smith Barney performed a variety of
financial and comparative analyses, including those described below. The summary
of such analyses does not purport to be a complete description of the analyses
underlying Salomon Smith Barney's opinion. The preparation of a fairness opinion
is a complex analytic process involving various determinations as to the most
appropriate and relevant methods
 
                                       46
<PAGE>   62
 
of financial analyses and the application of those methods to the particular
circumstances and, therefore, such an opinion is not readily susceptible to
summary description. Accordingly, Salomon Smith Barney believes that its
analyses must be considered as a whole and that selecting portions of its
analyses and factors, without considering all analyses and factors, could create
a misleading or incomplete view of the processes underlying such analyses and
opinion. In its analyses, Salomon Smith Barney made numerous assumptions with
respect to Storage Dimensions, Artecon, industry performance, general business,
economic, market and financial conditions and other matters, many of which are
beyond the control of Storage Dimensions and Artecon. The estimates contained in
such analyses and the valuation ranges resulting from any particular analysis
are not necessarily indicative of actual values or predictive of future results
or values, which may be significantly more or less favorable than those
suggested by such analyses. In addition, analyses relating to the value of
businesses or securities do not purport to be appraisals or to reflect the
prices at which businesses or securities actually may be sold. Accordingly, such
analyses and estimates are inherently subject to substantial uncertainty.
Salomon Smith Barney's opinion and analyses were only one of many factors
considered by the Board of Directors of Storage Dimensions in its evaluation of
the Merger and should not be viewed as determinative of the views of the Board
of Directors or management of Storage Dimensions with respect to the Merger
Consideration or the proposed Merger.
 
     Salomon Smith Barney's financial analyses assume an implied value for the
Storage Dimensions Common Stock component of the Merger Consideration of
approximately $51.6 million, calculated based on the aggregate number of shares
of Storage Dimensions Common Stock issuable in the Merger (12,891,817 shares,
based on the number of outstanding shares of Storage Dimensions Common Stock on
December 19, 1997) multiplied by the closing price for Storage Dimensions Common
Stock on December 19, 1997 ($4.00 per share).
 
     Selected Company Analysis. Using publicly available information, Salomon
Smith Barney analyzed, among other things, the market values and trading
multiples of Storage Dimensions and the following selected publicly traded
companies in the systems storage industry, consisting of: (i) small
capitalization disk systems companies: Auspex Systems, Inc.; Box Hill Systems
Corp.; Ciprico Inc.; Procom Technology, Inc.; and Storage Computer Corporation
(the "Small Cap Disk Systems Companies"); (ii) large capitalization disk systems
companies: EMC Corporation; Data General Corporation; MTI Technology
Corporation; and Network Appliance, Inc. (the "Large Cap Disk Systems
Companies"); and (iii) tape systems companies: Advanced Digital Information
Corporation; Exabyte Corporation; Overland Data, Inc.; and Storage Technology
Corporation (the "Tape Systems Companies" and, together with the Small Cap Disk
Systems Companies and the Large Cap Disk Systems Companies, the "Selected
Companies"). With respect to the Selected Companies, Salomon Smith Barney
focused primarily on the Small Cap Disk Systems Companies, which companies
Salomon Smith Barney considered to be most similar to Storage Dimensions and
Artecon. Salomon Smith Barney compared market values as a multiple of, among
other things, estimated calendar 1997 and 1998 net income, and adjusted market
values (market value, plus total debt, less cash, plus operating leases
capitalized at 12.5%) as multiples of, among other things, latest 12 months
revenues and earnings before interest and taxes ("EBIT"). Salomon Smith Barney
also compared the implied trading multiples for the combined company based on
the trading multiples of the Small Cap Disk Systems Companies. All multiples
were based on closing stock prices as of December 19, 1997. Net income estimates
for the Selected Companies were based on estimates of selected investment
banking firms and net income estimates for Storage Dimensions and Artecon were
based on internal estimates of the managements of Storage Dimensions and
Artecon. For purposes of its analysis, Salomon Smith Barney reviewed Artecon's
estimated calendar 1997 financial results pro forma for the Falcon Acquisition.
Applying a range of multiples for the Small Cap Disk Systems Companies of
estimated calendar 1997 net income and latest 12 months EBIT to the estimated
calendar 1997 net income and EBIT of Storage Dimensions resulted in negative
equity values for Storage Dimensions. The implied equity reference range for
Storage Dimensions based on latest 12 months revenue multiples of the Small Cap
Disk Systems Companies was not meaningful given the lack of profitability in the
operations of Storage Dimensions over the ninemonth period preceding December
19, 1997. Estimated calendar 1997 net income and latest 12 months EBIT multiples
for the Small Cap Disk System Companies also were deemed not to be meaningful
when applied to Artecon's estimated calendar 1997 net income and EBIT given the
fact that operating losses incurred by Falcon prior to the Falcon Acquisition
substantially
 
                                       47
<PAGE>   63
 
reduced Artecon's estimated calendar 1997 net income and EBIT. Applying a range
of multiples (excluding outliers) for the Small Cap Disk Systems Companies of
estimated calendar 1998 net income of 10.3x to 14.3x to corresponding financial
data for Storage Dimensions resulted in an equity reference range for Storage
Dimensions of approximately $3.79 to $5.26 per share, as compared to the market
value for Storage Dimensions of $4.00 per share based on a closing price of
Storage Dimensions Common Stock on December 19, 1997. Applying a range of
multiples (excluding outliers) for the Small Cap Disk Systems Companies of
estimated calendar 1998 net income and latest 12 months revenues of 10.3x to
14.3x and 0.9x to 1.5x, respectively, to the estimated calendar 1998 net income
and estimated calendar 1997 revenues of Artecon resulted in an equity reference
range for Artecon of approximately $78.1 million to $123.5 million, as compared
to the equity value implied by the Merger Consideration of approximately $51.6
million based on a closing price of Storage Dimensions Common Stock on December
19, 1997. Based on internal estimates of the managements of Storage Dimensions
and Artecon as to the estimated calendar 1998 earnings per share ("EPS") of the
pro forma combined company and the cost savings and other potential synergies
anticipated by the managements of Storage Dimensions and Artecon to result from
the Merger, and applying a range of estimated calendar 1998 price to earnings
multiples of the Small Cap Disk Systems Companies of 10.0x to 14.0x to
corresponding financial data for the pro forma combined company, resulted in an
implied equity reference range for the combined company of approximately $4.71
to $9.03 per share.
 
     Selected Merger and Acquisition Transactions Analysis. Using publicly
available information, Salomon Smith Barney analyzed the purchase price and
implied transaction value multiples paid in the following selected transactions
in the systems storage industry, consisting of (acquiror/target): Fujitsu
Limited/Amdahl Corporation (the "Fujitsu/Amdahl Transaction"); Compaq Computer
Corporation/Tandem Computers Incorporated; Gateway 2000, Inc./Advanced Logic
Research, Inc. (the "Gateway/Advanced Logic Transaction"); Silicon Graphics,
Inc./Cray Research, Inc.; EMC Corporation/McData Corporation; Hewlett-Packard
Company/Convex Computer Corporation; and Seagate Technology, Inc./Conner
Peripherals, Inc. (the "Seagate/Conner Transaction"). With respect to such
transactions, Salomon Smith Barney focused primarily on the Fujitsu/Amdahl
Transaction, the Gateway/Advanced Logic Transaction and the Seagate/ Conner
Transaction, which involved companies Salomon Smith Barney considered to be most
similar to Storage and Artecon (collectively, the "Selected Transactions").
Salomon Smith Barney compared purchase prices in the Selected Transactions as a
multiple of, among other things, latest 12 months net income, and transaction
values as multiples of, among other things, latest 12 months revenues and EBIT.
All multiples for the Selected Transactions were based on information available
at the time of announcement of the transaction. Applying the range of multiples
for the Selected Transactions of latest 12 months net income and EBIT to the
estimated calendar 1997 net income and EBIT of Storage Dimensions resulted in
negative equity values for Storage Dimensions. Latest 12 months net income
multiples for the Selected Transactions were deemed not to be meaningful when
applied to Artecon's estimated calendar 1997 net income given the fact that
operating losses incurred by Falcon prior to the Falcon Acquisition
substantially reduced Artecon's estimated calendar 1997 net income. Applying a
range of multiples (excluding outliers) for the Selected Transactions of latest
12 months revenues of 0.5x to 0.7x to estimated calendar 1997 revenues for
Storage Dimensions resulted in an equity reference range for Storage Dimensions
of approximately $5.28 to $7.06 per share, as compared to the market value for
Storage Dimensions of $4.00 per share based on a closing price of Storage
Dimensions Common Stock on December 19, 1997. Applying a range of multiples
(excluding outliers) for the Selected Transactions of latest 12 months revenues
and EBIT to the estimated calendar 1997 revenues and EBIT of Artecon resulted in
an equity reference range for Artecon of approximately $36.8 million to $76.9
million, as compared to the equity value implied by the Merger Consideration of
approximately $51.6 million based on a closing price of Storage Dimensions
Common Stock on December 19, 1997.
 
     No company, transaction or business used in the "Selected Company Analysis"
or "Selected Merger and Acquisition Transactions Analysis" as a comparison is
identical to Storage Dimensions, Artecon or the Merger. Accordingly, an analysis
of the results of the foregoing is not entirely mathematical; rather, it
involves complex considerations and judgments concerning differences in
financial and operating characteristics and other factors that could affect the
acquisition, public trading or other values of the Selected Companies, Selected
Transactions or the business segment, company or transaction to which they are
being compared.

     Contribution Analysis. Salomon Smith Barney analyzed the respective
contributions of Storage Dimensions and Artecon to, among other things, the
revenues, EBIT and net income of the combined company for the calendar year
ended December 1996 and latest 12 months ended September 30, 1997 and the
estimated revenues, EBIT and net income of the combined company for calendar
years 1997 and 1998, based on internal estimates of the managements of Storage
Dimensions and Artecon. This analysis indicated that (i) for the calendar year
ended December 31, 1996, Storage Dimensions would have contributed approximately
39.7% of revenues, 66.0% of EBIT and 64.2% of net income, and Artecon would have
contributed 60.3% of revenues, 34.0% of EBIT and 35.8% of net income, of the
combined company, (ii) for the latest 12 months ended September 30, 1997,
Storage Dimensions would have contributed approximately 41.5% of revenues, 45.7%
of EBIT and (92.5)% of net income, and Artecon would have contributed
approximately 58.5% of revenues, 54.3% of EBIT and 192.5% of net income, of the
combined company, (iii) in estimated calendar year 1997, Storage Dimensions
would contribute approximately 42.9% of revenues and (52.0)% of EBIT, and
Artecon would contribute approximately 57.1% of revenues and 152.0% of EBIT of
the combined company (net income figures were not meaningful given the fact that
Storage Dimensions net losses are expected to exceed Artecon's net income in
calendar 1997), and (iv) in estimated calendar year 1998, Storage Dimensions
would contribute approximately 41.7% of revenues, 23.6% of EBIT and 27.2% of net
income, and Artecon would contribute approximately 58.3% of revenues, 76.4% of
EBIT and 72.8% of net income, of the combined company. Based on the Merger
Consideration, current stockholders of Storage Dimensions and Artecon would own
approximately 37.5% and 62.5%, respectively, of the equity value of the combined
company upon consummation of the Merger (giving effect to the exercise of
Storage Dimensions stock options with an exercise price of less than $3.94 per
share), and Storage Dimensions and Artecon would constitute approximately 27.5%
and 72.5%, respectively, of the enterprise value of the combined company (giving
effect to the exercise of Storage Dimensions stock options with an exercise
price of less than $3.94 per share).
 
     Discounted Cash Flow Analysis. Salomon Smith Barney performed separate
discounted cash flow analyses of the projected free cash flows of Storage
Dimensions and Artecon for fiscal years ended December 31, 1998 through 2002,
based on internal estimates of the managements of Storage Dimensions and
Artecon. The stand-alone discounted cash flow analyses of Storage Dimensions and
Artecon were determined by (i) adding (x) the present value of the projected
free cash flows of Storage Dimensions and Artecon over the five-year period from
1998 to 2002 and (y) the present value of the estimated terminal values of
Storage Dimensions and Artecon in year 2002 and (ii) subtracting the current net
debt of Storage Dimensions and Artecon. The ranges of estimated terminal values
for Storage Dimensions and Artecon at the end of the five-year period were
calculated by applying terminal value multiples of 8.0x to 10.0x to the
projected 2002 earnings before interest, taxes, depreciation and amortization
("EBITDA") of Storage Dimensions and Artecon. The cash flows and terminal values
of Storage Dimensions and Artecon were discounted to present value using
discount rates ranging from 17.5% to 22.5%. Utilizing such terminal multiples
and discount rates, this analysis resulted in an equity reference range for
Storage Dimensions of approximately $3.63 to $4.82 per share, as compared to the
market value for Storage Dimensions of $4.00 per share based on a closing stock
price of Storage Dimensions Common Stock on December 19, 1997, and an equity
reference range for Artecon of approximately $75.8 million to $114.8 million, as
compared to the equity value implied by the Merger Consideration of
approximately $51.6 million.
 
     Pro Forma Merger Analysis. Salomon Smith Barney analyzed certain pro forma
effects resulting from the Merger, including, among other things, the impact of
the Merger on the projected earnings per share ("EPS") of Storage Dimensions for
the calendar year 1998, based on internal estimates of the managements of
Storage Dimensions and Artecon. The results of the pro forma merger analysis
suggested that the Merger could be accretive to the fully diluted EPS of Storage
Dimensions in calendar year 1998, both before and after giving effect to certain
cost savings and other potential synergies anticipated by the managements of
Storage Dimensions and Artecon to result from the Merger. The actual results
achieved by the combined company may vary from projected results and the
variations may be material.
 
     Other Factors and Comparative Analyses. In rendering its opinion, Salomon
Smith Barney considered certain other factors and conducted certain other
comparative analyses, including, among other things, a review of (i) historical
and projected financial results of Storage Dimensions and Artecon; (ii) the
history of
 
                                       49
<PAGE>   65
 
trading prices and volume for Storage Dimensions Common Stock and the
relationship between movements in Storage Dimensions Common Stock, movements in
the common stock of the Small Cap Disk System Companies and the Large Cap Disk
System Companies and movements in the NASDAQ Composite Index; (iii) selected
published analysts' reports on Storage Dimensions, including analysts' estimates
as to the earnings growth potential of Storage Dimensions; and (iv) the pro
forma ownership of the combined company, both before and after giving effect to
the conversion of the Storage Preferred Stock issuable in the Merger.
 
     Pursuant to the terms of Salomon Smith Barney's engagement, Storage
Dimensions has agreed to pay Salomon Smith Barney for its services in connection
with the Merger an aggregate financial advisory fee based on a percentage of the
total market value of Storage Dimensions on a fully diluted basis. The fee
payable to Salomon Smith Barney is currently estimated to be approximately
$606,800. Storage Dimensions has also agreed to reimburse Salomon Smith Barney
for travel and other out-of-pocket expenses incurred by Salomon Smith Barney in
performing its services, including the fees and expenses of its legal counsel,
and to indemnify Salomon Smith Barney and related persons against certain
liabilities, including liabilities under the federal securities laws, arising
out of Salomon Smith Barney's engagement.
 
     Salomon Smith Barney has advised Storage Dimensions that, in the ordinary
course of business, Salomon Smith Barney and its affiliates may actively trade
or hold the securities of Storage Dimensions for their own account or for the
account of customers and, accordingly, may at any time hold a long or short
position in such securities. Salomon Smith Barney has in the past provided
investment banking services to Storage Dimensions unrelated to the Merger, for
which services Salomon Smith Barney has received compensation. In addition,
Salomon Smith Barney and its affiliates (including Travelers Group Inc. and its
affiliates) may maintain relationships with Storage Dimensions and Artecon.
 
     Salomon Smith Barney is an internationally recognized investment banking
firm and was selected by Storage Dimensions based on its experience, expertise
and familiarity with Storage Dimensions and its business. Salomon Smith Barney
regularly engages in the valuation of businesses and their securities in
connection with mergers and acquisitions, negotiated underwritings, competitive
bids, secondary distributions of listed and unlisted securities, private
placements and valuations for estate, corporate and other purposes.
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
     In considering the respective recommendations of the Storage Dimensions
Board and the Artecon Board with respect to the Merger, the Storage Dimensions
stockholders and Artecon shareholders should be aware that certain members of
the Artecon Board and the Storage Dimensions Board and certain executive
officers of each company have certain interests in the Merger that are in
addition to the interests of shareholders generally.
 
     In particular, pursuant to the Reorganization Agreement, James Lambert,
Jason Sauey and W.R. Sauey, current directors of Artecon, will become members of
the Storage Dimensions Board at the Effective Time. Current Storage Dimensions
directors Chong Sup Park and Brian Fitzgerald will remain on the Board. In
addition, James Lambert, Tesfaye Hailemichael and Dana Kammersgard, currently
President and Chief Executive Officer, Chief Financial Officer and a director of
Artecon, respectively, shall serve as President and Chief Executive Officer,
Chief Financial Officer and Secretary of Storage Dimensions, respectively,
following the Merger.
 
     In addition, in connection with the Merger, Storage Dimensions and each of
David Eeg and Robert Bylin, President and Chief Executive Officer and Chief
Financial Officer of Storage Dimensions, respectively, amended the employment
agreements of such persons to provide certain severance benefits upon
termination of their relationship with Storage Dimensions. Moreover, as a result
of the Merger, stock options held by all Storage Dimensions employees, including
executive officers (but excluding options granted after December 22, 1997), will
become fully vested and exercisable. See "-- Effect on Storage Dimensions
Options" and "CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS OF STORAGE
DIMENSIONS."

<PAGE>   66
 
     W.R. Sauey, a director of Artecon, and certain entities affiliated with Mr.
Sauey, are the owners of an aggregate of 2,494,159 shares of Artecon Preferred
Stock and will receive all of the Storage Dimensions Preferred Stock being
issued in the Merger.
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
     The following discussion summarizes the material federal income tax
considerations of the Merger that are generally applicable to holders of Artecon
Common Stock and Artecon Preferred Stock. This discussion is based on currently
existing provisions of the Code, existing and proposed Treasury Regulations
thereunder and current administrative rulings and court decisions, all of which
are subject to change. Any such change, which may or may not be retroactive,
could alter the tax consequences to Storage Dimensions, Merger Sub, Artecon or
the Artecon shareholders as described herein.
 
     The Artecon shareholders should be aware that this discussion does not deal
with all federal income tax considerations that may be relevant to particular
Artecon shareholders in light of their particular circumstances, such as
shareholders who are dealers in securities, banks, insurance companies or
tax-exempt organizations, who are subject to the alternative minimum tax
provisions of the Code, who are foreign persons, who acquired their shares in
connection with stock option or stock purchase plans or in other compensatory
transactions or who hold their shares as part of a hedging, straddle, conversion
or other risk reduction transaction. In addition, the following discussion does
not address the tax consequences of the Merger under foreign, state or local tax
laws or the tax consequences of any other transactions effectuated prior to or
after the Merger (whether or not such transactions are in connection with the
Merger). THE ARTECON SHAREHOLDERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS AS
TO THE SPECIFIC CONSEQUENCES OF THE MERGER, INCLUDING THE APPLICABLE FEDERAL,
STATE, LOCAL AND FOREIGN TAX CONSEQUENCES TO THEM OF THE MERGER IN THEIR
PARTICULAR CIRCUMSTANCES.
 
     Neither Storage Dimensions nor Artecon has requested a ruling from the
Internal Revenue Service (the "IRS") with regard to any of the federal income
tax consequences of the Merger. The obligations of Storage Dimensions and
Artecon to consummate the Merger are conditioned on the receipt by Storage
Dimensions of an opinion from Wilson Sonsini Goodrich & Rosati, P.C. ("Wilson
Sonsini") and the receipt by Artecon of an opinion from Cooley Godward LLP
("Cooley Godward"), that the Merger constitutes a reorganization (a
"Reorganization") within the meaning of Section 368(a) of the Code
(collectively, the "Tax Opinions"). The Tax Opinions will be subject to certain
assumptions and qualifications and will be based on the truth and accuracy of
certain representations of Storage Dimensions, Merger Sub, Artecon and certain
Artecon shareholders, including representations in certain certificates
delivered to counsel by the respective managements of Storage Dimensions, Merger
Sub, Artecon and certain Artecon shareholders. Of particular importance are the
assumptions and representations relating to the "continuity of interest"
requirement discussed below.
 
     The discussion below assumes that the Merger will qualify as a
Reorganization, based upon the Tax Opinions. The tax description set forth below
has been prepared and reviewed by Wilson Sonsini and Cooley Godward, and in
their opinion, to the extent such description relates to statements of law, it
is correct in all material respects. Subject to the limitations and
qualifications referred to herein, and as a result of the Merger's qualifying as
a Reorganization, the following federal income tax consequences should, under
currently applicable law, result:
 
     (a) No gain or loss will be recognized by the holders of Artecon Common
         Stock and Artecon Preferred Stock upon the receipt of Storage
         Dimensions Common Stock or Storage Dimensions Preferred Stock, solely
         in exchange for such Artecon Common Stock or Artecon Preferred Stock in
         the Merger (except to the extent of cash received in connection with
         Dissenting Shares and in lieu of a fractional share of Storage
         Dimensions Common Stock).
 
     (b) The aggregate tax basis of the Storage Dimensions Common Stock or
         Storage Dimensions Preferred Stock so received by the Artecon
         shareholders in the Merger (including any fractional share of Storage
         Dimensions Common Stock not actually received) will be the same as the
         aggregate tax
 
                                       51
<PAGE>   67
 
         basis of the Artecon Common Stock or Artecon Preferred Stock, as the
         case may be, surrendered in exchange therefor.
 
     (c) The holding period of the Storage Dimensions Common Stock or Storage
         Dimensions Preferred Stock so received by each Artecon shareholder in
         the Merger will include the period for which the Artecon Common Stock
         or Artecon Preferred Stock, as the case may be, surrendered in exchange
         therefor was considered to be held, provided that the Artecon Common
         Stock or Artecon Preferred Stock so surrendered is held as a capital
         asset at the Effective Time of the Merger.
 
     (d) Cash payments received by holders of Artecon Common Stock in lieu of a
         fractional share of Storage Dimensions Common Stock will be treated as
         if such fractional share had been issued in the Merger and then
         redeemed by Storage Dimensions. An Artecon shareholder receiving such
         cash will recognize gain or loss upon such payment, measured by the
         difference (if any) between the amount of cash received and the basis
         in such fractional share. The gain or loss should be capital gain or
         loss provided that such share of Artecon Common Stock was held as a
         capital asset at the Effective Time of the Merger.
 
     (e) A shareholder of Artecon who exercises dissenters' rights under any
         applicable law with respect to a share of Artecon Common Stock or
         Artecon Preferred Stock and receives payments for such stock in cash
         will recognize capital gain or loss (if such stock was held as a
         capital asset at the Effective Time of the Merger) measured by the
         difference between the amount of cash received and the shareholder's
         basis in such share, provided such payment is neither essentially
         equivalent to a dividend within the meaning of Section 302 of the Code
         nor has the effect of a distribution of a dividend within the meaning
         of Section 356(a)(2) of the Code (collectively, a "Dividend Equivalent
         Transaction"). A sale of Artecon shares incident to an exercise of
         dissenters' rights will generally not be a Dividend Equivalent
         Transaction if, as a result of such exercise, the dissenting
         shareholder owns no shares of Storage Dimensions capital stock (either
         actually or constructively within the meaning of Section 318 of the
         Code).
 
     (f) None of Storage Dimensions, Merger Sub or Artecon will recognize gain
         solely as a result of the Merger.
 
     One key assumption underlying the Tax Opinions is that the "continuity of
interest" requirement will be satisfied in the Merger. To satisfy the
"continuity of interest" requirement, the Artecon shareholders must not,
pursuant to a plan or intent existing at or prior to the Effective Time of the
Merger, dispose of or transfer so much of either (i) their Artecon Common Stock
or Artecon Preferred Stock in anticipation of the Merger or (ii) the Storage
Dimensions Common Stock or Storage Dimensions Preferred Stock to be received in
the Merger (collectively, "Planned Dispositions"), such that the Artecon
shareholders, as a group, would no longer have a significant equity interest in
the Artecon business being conducted by Storage Dimensions after the Merger.
Artecon shareholders will generally be regarded as having a significant equity
interest as long as the Storage Dimensions Common Stock or Storage Dimensions
Preferred Stock received in the Merger (after taking into account Planned
Dispositions), in the aggregate, represents a substantial portion of the entire
consideration received by the Artecon shareholders in the Merger. No assurance
can be made that the "continuity of interest" requirement will be satisfied, and
if such requirement is not satisfied, the Merger would not be treated as a
Reorganization.
 
     A successful IRS challenge to the Reorganization status of the Merger (as a
result of a failure of the "continuity of interest" requirement or otherwise)
would result in significant tax consequences. An Artecon shareholder would
recognize gain or loss with respect to each share of Artecon Common Stock or
Artecon Preferred Stock surrendered equal to the difference between the Artecon
shareholder's basis in such share and the fair market value, as of the Effective
Time of the Merger, of the Storage Dimensions Common Stock or Storage Dimensions
Preferred Stock received in exchange therefor. In such event, an Artecon
shareholder's aggregate basis in the Storage Dimensions Common Stock or Storage
Dimensions Preferred Stock so received would equal its fair market value, and
such shareholder's holding period for such stock would begin the day after the
Merger.
 
                                       52
<PAGE>   68
 
     Certain noncorporate Artecon shareholders may be subject to backup
withholding at a rate of 31% on cash payments received in lieu of a fractional
share interest in Storage Dimensions Common Stock or Dissenting Shares. Backup
withholding will not apply, however, to a shareholder who furnishes a current
taxpayer identification number ("TIN") and certifies that he or she is not
subject to backup withholding on the substitute Form W-9 included in the
Transmittal Letter, who provides a certificate of foreign status on Form W-8, or
who is otherwise exempt from backup withholding. A shareholder who fails to
provide the correct TIN on Form W-9 may be subject to a $50 penalty imposed by
the IRS.
 
     Each Artecon shareholder will be required to retain records and file with
such holder's U.S. federal income tax return a statement setting forth certain
facts relating to the Merger.
 
ACCOUNTING TREATMENT
 
     For accounting purposes, the Merger will be treated as a purchase of
Storage Dimensions by Artecon since the holders of Artecon capital stock would
hold and have voting power with respect to approximately 62.5% of the total
issued and outstanding voting capital stock of Storage Dimensions immediately
following the Merger. See "STOCK OWNERSHIP OF STORAGE DIMENSIONS FOLLOWING THE
MERGER." The purchase price will be determined by reference to the average of
the closing bid and ask prices per share of Storage Dimensions Common Stock as
traded on the Nasdaq National Market on December 18, 1997.
 
EFFECT ON ARTECON OPTIONS, WARRANTS AND RIGHTS
 
     Under the terms of the Reorganization Agreement, each Artecon option,
warrant or right to purchase Artecon Common Stock shall be converted into an
option, warrant or right to acquire, on the same terms and conditions as were
applicable to such option, warrant or right on the date of the Reorganization
Agreement, the number of shares of Storage Dimensions Common Stock equal to the
number of shares of Artecon Common Stock subject to such Artecon option, warrant
or right immediately prior to the Effective Time multiplied by the Exchange
Ratio, rounding down to the nearest whole share (with cash, less the applicable
exercise price, being payable for any fraction of a share). The per share
exercise price under each such Artecon option, warrant or right shall be
adjusted by dividing the per share exercise price under such Artecon option,
warrant or right by the Exchange Ratio and rounding up to the nearest cent.
After the Effective Time, Storage Dimensions will file a Registration Statement
on Form S-8 with respect to the shares of Storage Dimensions Common Stock
subject to such options, if any.
 
EFFECT ON STORAGE DIMENSIONS OPTIONS
 
     As a result of the Merger, all outstanding options granted prior to
December 22, 1997 under the 1996 Stock Option Plan and 1993 Stock Option Plan
shall become fully vested and exercisable. No other adjustments to any
outstanding Storage Dimensions stock options will occur as a result of the
Merger.
 
REGULATORY MATTERS
 
     The consummation of the Merger is subject to the expiration or termination
of the relevant waiting period under the Hart-Scott-Rodino Antitrust
Improvements Act of 1976, as amended (the "HSR Act"). Storage Dimensions and
W. R. Sauey, a principal shareholder of Artecon, have filed notification and
report forms under the HSR Act. Artecon is not required to make any filings
under the HSR Act in connection with the Merger, as it is exempt from such
filing requirements under certain provisions of the HSR Act. Effective February
13, 1998 the waiting period under the HSR Act was terminated. See "OTHER
MATTERS -- Regulatory Approvals Required."
 
FEDERAL SECURITIES LAW CONSEQUENCES
 
     All of the Storage Dimensions Common Stock issued in connection with the
Merger will be freely transferable, except that any Storage Dimensions Common
Stock received by persons who are deemed to be "affiliates" (as such term is
defined under the Securities Act) of Artecon or Storage Dimensions prior to the
 
                                       53
<PAGE>   69
 
Merger may be sold by them only in transactions permitted by the resale
provisions of Rule 145 under the Securities Act with respect to affiliates of
Artecon, or Rule 144 under the Securities Act with respect to persons who are or
become affiliates of Storage Dimensions, or as otherwise permitted under the
Securities Act. Persons who may be deemed to be affiliates of Artecon or Storage
Dimensions generally include individuals or entities that control, are
controlled by, or are under common control with, such corporation and may
include certain officers and directors of such corporation as well as principal
stockholders of such corporation.
 
     Affiliates of Artecon may not sell their shares of Storage Dimensions
Common Stock acquired in connection with the Merger, except pursuant to an
effective registration under the Securities Act covering such shares or in
compliance with Rule 145 (or Rule 144 under the Securities Act in the case of
persons who are or become affiliates of Storage Dimensions) or another
applicable exemption from the registration requirements of the Securities Act.
In general, under Rule 145, for one year following the Effective Time an
affiliate (together with certain related persons) would be entitled to sell
shares of Storage Dimensions Common Stock acquired in connection with the Merger
only through unsolicited "brokers" transactions" or in transactions directly
with a "market maker," as such terms are defined in Rule 145. Additionally, the
number of shares to be sold by an affiliate (together with certain related
persons and certain persons acting in concert) within any three-month period for
purposes of Rule 145 may not exceed the greater of 1% of the outstanding shares
of Storage Dimensions Common Stock or the average weekly trading volume of such
stock during the four calendar weeks preceding such sale. Rule 145 would only
remain available, however, to affiliates if Storage Dimensions remained current
with its informational filings under the Exchange Act. One year after the
Effective Time, an affiliate would be able to sell such Storage Dimensions
Common Stock without such manner of sale or volume limitations provided that
Storage Dimensions was current with its Exchange Act informational filings and
such affiliate was not then an affiliate of Storage Dimensions. Two years after
the Effective Time, an affiliate would be able to sell such shares of Storage
Dimensions Common Stock without any restrictions so long as such affiliate had
not been an affiliate of Storage Dimensions for at least three months prior
thereto.
 
     The shares of Storage Dimensions Preferred Stock issuable in the Merger
will not be registered and will not be transferable unless registered or
transferred pursuant to an exemption from the Securities Act. The shares of
Storage Dimensions Common Stock issuable upon conversion of the Storage
Dimensions Preferred Stock shall be registered under the Securities Act but
shall be subject to restrictions on transfer for stock held by affiliates.
 
STOCK LISTING
 
     It is a condition to Storage Dimensions' and Artecon's obligation to
consummate the Merger that the shares of Storage Dimensions Common Stock to be
issued pursuant to the Reorganization Agreement be approved for listing on the
Nasdaq National Market. An application will be filed for listing such shares of
Storage Dimensions Common Stock on the Nasdaq National Market prior to
consummation of the Merger. Upon consummation of the Merger, the name of Storage
Dimensions will be changed to "Artecon, Inc." and the Storage Dimensions Common
Stock will be traded on the Nasdaq National Market under the symbol "ARTE."
Following the Merger, the Storage Dimensions Preferred Stock will not be
publicly traded.
 
APPRAISAL AND DISSENTERS' RIGHTS
 
     If the Reorganization Agreement is approved by the required vote of Artecon
shareholders and is not abandoned or terminated, holders of Artecon capital
stock who did not vote in favor of the Merger may, by complying with Sections
1300 through 1312 of the CGCL, be entitled to dissenters' rights as described
therein. The record holders of the shares of Artecon capital stock that are
eligible to, and do, exercise their dissenters' rights with respect to the
Merger are referred to herein as "Dissenting Shareholders," and the shares of
stock with respect to which they exercise dissenters' rights are referred to
herein as "Dissenting Shares."
 
                                       54
<PAGE>   70
 
     The following discussion is not a complete statement of the CGCL relating
to dissenters' rights, and is qualified in its entirety by reference to Sections
1300 through 1312 of the CGCL attached to this Joint Proxy Statement/Prospectus
as Appendix D and incorporated herein by reference. This discussion and Sections
1300 through 1312 of the CGCL should be reviewed carefully by any holder who
wishes to exercise statutory dissenters' rights or wishes to preserve the right
to do so, since failure to comply with the required procedures will result in
the loss of such rights.
 
     Shares of Artecon capital stock must satisfy each of the following
requirements to qualify as Dissenting Shares under the CGCL: (i) the shares of
Artecon capital stock must have been outstanding on the Artecon Record Date;
(ii) the shares of Artecon capital stock must not have been voted in favor of
the Merger; (iii) the holder of such shares of Artecon capital stock must make a
written demand that Artecon repurchase such shares of Artecon capital stock at
fair market value (as described below); and (iv) the holder of such shares of
Artecon capital stock must submit certificates for endorsement (as described
below). A vote by proxy or in person against the Merger does not in and of
itself constitute a demand for appraisal under the CGCL.
 
     Pursuant to Sections 1300 through 1312 of the CGCL, holders of Dissenting
Shares may require Artecon to repurchase their Dissenting Shares at a price
equal to the fair market value of such shares determined as of the day before
the first announcement of the terms of the Merger, excluding any appreciation or
depreciation as a consequence of the proposed Merger, but adjusted for any stock
split, reverse stock split or stock dividend that becomes effective thereafter.
 
     Within ten days following approval of the Merger by Artecon shareholders,
Artecon is required to mail to each holder of shares of Artecon not voted in
favor of the Merger a notice of the approval of the Merger, a statement of the
price determined by Artecon to represent the fair market value of Dissenting
Shares (which shall constitute an offer by Artecon to purchase such Dissenting
Shares at such stated price), and a description of the procedures for such
holders to exercise their rights as Dissenting Shareholders.
 
     Within 30 days after the date on which the notice of the approval of the
Merger by the outstanding shares is mailed to Dissenting Shareholders, a
Dissenting Shareholder must demand that Artecon repurchase such shareholder's
Dissenting Shares in a statement setting forth the number and class of
Dissenting Shares held of record by such Dissenting Shareholder that the
Dissenting Shareholder demands that Artecon purchase, and a statement of which
the Dissenting Shareholder claims to be the fair market value of the Dissenting
Shares as of the day before the announcement of the proposed Merger. The
statement of fair market value in such demand by the Dissenting Shareholder
constitutes an offer by the Dissenting Shareholder to sell the Dissenting Shares
at such price within such 30-day period. Such holder must also submit to Artecon
or its transfer agent certificates representing any Dissenting Shares that the
Dissenting Shareholder demands Artecon purchase, so that such Dissenting Shares
may either be stamped or endorsed with the statement that the shares are not
Dissenting Shares or exchanged for certificates of appropriate denomination so
stamped or endorsed.
 
     If upon the Dissenting Shareholder's surrender of the certificates
representing the Dissenting Shares Artecon and a Dissenting Shareholder agree
upon the price to be paid for the Dissenting Shares and agree that such shares
are Dissenting Shares, then the agreed price is required by law to be paid to
the Dissenting Shareholder within the later of 30 days after the date of such
agreement or 30 days after any statutory or contractual conditions to the
consummation of the Merger are satisfied or waived.
 
     If Artecon and a Dissenting Shareholder disagree as to the price for such
Dissenting Shares or disagree as to whether such shares are entitled to be
classified as Dissenting Shares, such holder has the right to bring an action in
California Superior Court, within six months after the date on which the notice
of the approval of the Merger by Artecon shareholders is mailed, to resolve such
dispute. In such action, the court will determine whether the shares of Artecon
Common Stock held by such shareholder are Dissenting Shares, the fair market
value of such shares of Artecon Common Stock, or both. The CGCL provides, among
other things, that a Dissenting Shareholder may not withdraw the demand for
payment of the fair market value of Dissenting Shares unless Artecon consents to
such request for withdrawal.
 
                                       55

     Under the DGCL, Storage Dimensions stockholders are not entitled to
dissenters' or appraisal rights with respect to the proposed Merger.
 
MERGER EXPENSES AND FEES AND OTHER COSTS
 
     Each of Storage Dimensions and Artecon will pay its own expenses in
connection with the Merger, with certain exceptions in case of certain
terminations of the Reorganization Agreement. See "THE REORGANIZATION
AGREEMENT -- Termination Fees."
 
                          THE REORGANIZATION AGREEMENT
 
     The description of the Reorganization Agreement set forth below does not
purport to be complete and is qualified in its entirety by reference to the
Reorganization Agreement, a copy of which is attached to this Joint Proxy
Statement/Prospectus as Annex A and incorporated herein by reference. All
stockholders are urged to read the Reorganization Agreement in its entirety.
 
TERMS OF THE MERGER
 
     The Merger. At the Effective Time and subject to and upon the terms and
conditions of the Reorganization Agreement and the CGCL, Merger Sub will be
merged with and into Artecon, the separate corporate existence of Merger Sub
will cease, and Artecon will continue as the surviving corporation and a
wholly-owned subsidiary of Storage Dimensions (the "Surviving Corporation"). In
the Merger, each outstanding share of Artecon Common Stock (other than
Dissenting Shares) will be converted into the right to receive the number of
shares of Storage Dimensions Common Stock, equal to the Exchange Ratio, which,
for purposes of this Joint Proxy Statement/Prospectus, has been estimated to be
approximately 2.16. The exact number of shares of Storage Dimensions Common
Stock into which each share of Artecon Common Stock will be converted will be
determined as of the Effective Time as follows: the Exchange Ratio will be a
fraction the numerator of which is the number of Merger Shares (as defined
below) and the denominator of which is the number of Artecon Shares (as defined
below). "Merger Shares" shall mean the shares of Storage Dimensions Common Stock
to be issued to holders of Artecon Common Stock in the Merger and shall be equal
to the product of (A) 1.5641 times (B) the sum of (x) the number of shares of
Storage Dimensions Common Stock outstanding immediately prior to the Effective
Time plus (y) the maximum number of shares of Storage Dimensions Common Stock
issuable upon exercise of any options to purchase Storage Dimensions Common
Stock (without regard to vesting) with option exercise prices of less than
$3.96875. "Artecon Shares" shall mean the sum of (A) the number of shares of
Artecon Common Stock outstanding immediately prior to the Effective Time plus
(B) the maximum number of shares of Artecon Common Stock underlying any
instruments convertible into or exchangeable for Artecon Common Stock (without
regard to vesting) outstanding immediately prior to the Effective Time,
including shares of Artecon Preferred Stock other than the 2,494,159 shares of
Artecon Preferred stock held by W.R. Sauey and certain affiliates of W.R. Sauey.
Such shares of Artecon Preferred Stock held by W.R. Sauey and such affiliates
(the "Sauey Preferred") will be converted into 2,494,159 shares of Storage
Dimensions Preferred Stock pursuant to the Merger. Although the Applicable
Multiple is fixed, the Exchange Ratio is subject to change based upon changes in
the number of shares of Storage Dimensions Common Stock and Artecon Common Stock
outstanding immediately prior to the Effective Time. While dollar fluctuations
in the market price of Storage Dimensions Common Stock will not affect the
Exchange Ratio, they would change the aggregate value of the shares of Storage
Dimensions Common Stock issued in the Merger.
 
     In addition, each share of Artecon Preferred Stock (other than Dissenting
Shares) outstanding as of the Effective Time will be converted into the right to
receive one share of newly designated Storage Dimensions Preferred Stock. All
holders of Artecon Preferred Stock, other than the Sauey Preferred, have agreed
to convert such Artecon Preferred Stock into shares of Artecon Common Stock
prior to the Effective Time, which shares will then be converted into Storage
Dimensions Common Stock pursuant to the Merger. In addition, outstanding
options, warrants and rights to purchase Artecon Common Stock will be converted
into options, warrants and rights to purchase Storage Dimensions Common Stock on
the same basis as the Artecon
 
                                       56
<PAGE>   72
 
Common Stock and appropriate adjustment will be made to the exercise price of
each such option, warrant or right.
 
     Effective Time. Contemporaneously with or as promptly as practicable after
the approval of the Merger Proposal by the Artecon shareholders and the approval
of the Business Combination Proposal by the Storage Dimensions stockholders, and
subject to the satisfaction or waiver of the other conditions to the Merger, the
Merger will be consummated by filing a Certificate of Merger, together with any
required related certificates, with the Secretary of State of the State of
California in accordance with the provisions of the CGCL.
 
     Articles and Certificate of Incorporation and Bylaws. The Reorganization
Agreement provides that the Articles of Incorporation and Bylaws of Merger Sub,
as in effect immediately prior to the Effective Time, will be the Articles of
Incorporation and Bylaws of the Surviving Corporation, except that the name of
the Surviving Corporation will be changed to "Artecon California." In addition,
the Reorganization Agreement provides that the Certificate of Incorporation of
Storage Dimensions will be amended effective on the Effective Time to (i) change
its name from Storage Dimensions to "Artecon, Inc."; (ii) provide for a
classified Board of Directors whereby the directors will be separated into three
classes, with members of each class serving for a three year term; (iii) provide
that a director may not be removed from office without cause except, until the
third annual meeting of stockholders of Storage Dimensions after the Merger, by
the affirmative vote of at least 80% of the outstanding voting stock of Storage
Dimensions and by the affirmative vote of at least 66 2/3% of the outstanding
voting stock of Storage Dimensions thereafter; and (iv) designate a new Series A
Preferred Stock, of which 2,494,159 shares will be authorized. See "OTHER
AGREEMENTS -- Amendment to Storage Dimensions Certificate of Incorporation."
 
     Directors and Officers. Pursuant to the Reorganization Agreement, James
Lambert, Jason Sauey and W.R. Sauey, currently directors of Artecon, will become
members of the Storage Dimensions Board at the Effective Time. Brian Fitzgerald
and Chong Sup Park, currently directors of Storage Dimensions, will remain on
the Storage Dimensions Board. In addition, James Lambert, Tesfaye Hailemichael
and Dana Kammersgard, currently the President and Chief Executive Officer, Chief
Financial Officer and a director, respectively, of Artecon, will be appointed
President and Chief Executive Officer, Chief Financial Officer and Secretary,
respectively, of Storage Dimensions at the Effective Time. At the Effective
Time, the directors of Artecon, as the surviving corporation in the Merger, will
be W. R. Sauey and James Lambert, each to hold office in accordance with the
Articles of Incorporation and Bylaws of the Surviving Corporation.
 
     Conversion of Artecon Capital Stock in the Merger. At the Effective Time,
each share of Artecon Common Stock issued and outstanding immediately prior to
the Effective Time (other than shares owned by Storage Dimensions, Artecon,
Merger Sub or any direct or indirect wholly-owned subsidiary of Storage
Dimensions or Artecon and other than Dissenting Shares) will be converted into
the right to receive approximately 2.16 shares of Storage Dimensions Common
Stock. At the Effective Time, each share of Artecon Preferred Stock issued and
outstanding immediately prior to the Effective Time (other than Dissenting
Shares) will be converted into the right to receive one share of newly
designated Storage Dimensions Preferred Stock. Cash will be paid to Artecon
shareholders in lieu of any fractional shares of Storage Dimensions Common Stock
to which they would otherwise be entitled. See "THE MERGER -- Fractional Shares"
and "-- Exchange of Certificates."
 
     Artecon Options, Warrants and Rights. Under the terms of the Reorganization
Agreement, each option, warrant or right to purchase Artecon Common Stock
outstanding at the Effective Time, if any, will be converted into an equivalent
option, warrant or right to acquire the number of shares of Storage Dimensions
Common Stock equal to the number of shares of Artecon Common Stock subject to
such Artecon option, warrant or right immediately prior to the Effective Time
multiplied by the Exchange Ratio, rounding down to the nearest whole share (with
cash, less the applicable exercise price, being payable for any fraction of a
share). The per share exercise price under each such Artecon option, warrant or
right shall be adjusted by dividing the per share exercise price under such
Artecon option, warrant or right by the Exchange Ratio and rounding up to the
nearest cent. Each such option, warrant and right issued in the Merger will
continue to have and be subject to the same terms and conditions set forth in
the stock option plan or other agreement
 
                                       57
<PAGE>   73
 
under which such option, warrant or right was issued, as in effect on the date
of the Reorganization Agreement. See "THE MERGER -- Effect on Artecon Options,
Warrants and Rights."
 
     Fractional Shares. No certificates or scrip representing less than one
share of Storage Dimensions Common Stock shall be issued in connection with the
Merger. In lieu of any such fractional share, each holder of a certificate or
certificates representing Artecon Common Stock who would otherwise have been
entitled to a fraction of a share of Storage Dimensions Common Stock upon
surrender of such certificates for exchange shall be paid in cash upon such
surrender the dollar amount determined by multiplying such fraction by the
closing price per share of Storage Dimensions Common Stock as reported on the
Nasdaq National Market on the Effective Date.
 
EXCHANGE OF CERTIFICATES
 
     Exchange Agent. Storage Dimensions will supply, or shall cause to be
supplied, to Boston Equiserve, as Exchange Agent, certificates evidencing shares
of Storage Dimensions Common Stock and Storage Dimensions Preferred Stock to be
issued in exchange for outstanding Artecon Common Stock and Artecon Preferred
Stock, respectively, in accordance with the Reorganization Agreement.
 
     Exchange Procedures. At or as soon as practicable after the Effective Time,
the holders of Artecon Common Stock and Artecon Preferred Stock will surrender
their certificates representing Artecon Common Stock or Artecon Preferred Stock
in exchange for certificates evidencing Storage Dimensions Common Stock or
Storage Dimensions Preferred Stock, as the case may be.
 
     Upon surrender of a certificate representing Artecon Common Stock or
Artecon Preferred Stock for cancellation to the Exchange Agent, and such other
customary documents as may be required, the holder of such certificate will be
entitled to receive in exchange therefor: (i) certificates evidencing that
number of whole shares of Storage Dimensions Common Stock or Storage Dimensions
Preferred Stock which such holder has the right to receive in the Merger; (ii)
any dividends or other distributions on the shares of Storage Dimensions Common
Stock or Storage Dimensions Preferred Stock which such holder is entitled to
receive; and (iii) cash in respect of fractional shares of Storage Dimensions
Common Stock, and the certificate representing Artecon Common Stock or Artecon
Preferred Stock so surrendered will be canceled. In the event of a transfer of
ownership of shares of Artecon Common Stock or Artecon Preferred Stock which is
not registered in the transfer records of Artecon as of the Effective Time, the
Merger Consideration, the shares of Storage Dimensions Common Stock and Storage
Dimensions Preferred Stock (and any cash in lieu of fractional shares) to be
issued in exchange therefor, may be issued and paid to a transferee if the
certificate evidencing such shares of Artecon Common Stock or Artecon Preferred
Stock is presented to the Exchange Agent, accompanied by all documents required
to evidence and effect such transfer and by evidence that any applicable stock
transfer taxes have been paid. Until so surrendered, each outstanding
certificate that, prior to the Effective Time, represented shares of Artecon
Common Stock or Artecon Preferred Stock will be deemed from and after the
Effective Time, for all corporate purposes (other than payment of dividends or
as described below under "Withholding Rights"), to evidence the ownership of the
number of whole shares of Storage Dimensions Common Stock or Storage Dimensions
Preferred Stock into which such shares of Artecon Common Stock or Artecon
Preferred Stock shall have been so converted.
 
     Withholding Rights. The Exchange Agent will be entitled to deduct and
withhold from the Storage Dimensions Common Stock or Storage Dimensions
Preferred Stock otherwise payable pursuant to the Reorganization Agreement to
any Artecon shareholder such amounts as Storage Dimensions or its designee is
required to deduct and withhold with respect to the making of such payment under
any provision of federal, state, local or foreign tax law. To the extent that
amounts are so withheld by Storage Dimensions or its designee, such withheld
amounts shall be treated for purposes of the Reorganization Agreement as having
been paid to the holder of the shares of Artecon Common Stock or Artecon
Preferred Stock in respect of which such deduction and withholding was made by
Storage Dimensions or its designee.
 
     Lost, Stolen or Destroyed Certificates. In the event any certificates
representing shares of Artecon Common Stock or Artecon Preferred Stock have been
lost, stolen or destroyed, the Exchange Agent will issue shares of Storage
Dimensions Common Stock or Storage Dimensions Preferred Stock in exchange for
such
 
                                       58
<PAGE>   74
 
lost, stolen or destroyed certificates upon the making of an affidavit of that
fact by the owner of such certificates as indemnity against any claim that may
be made against Storage Dimensions, Merger Sub or its designee with respect to
the certificates alleged to have been lost, stolen or destroyed.

execution of the Reorganization Agreement until the Effective Time (the
"Pre-Closing Period"), it will provide Storage Dimensions with reasonable access

Artecon has also agreed that, during the Pre-Closing Period, it will not:
 
          (a) declare, accrue, set aside or pay any dividend or make any other

     date of the Reorganization Agreement or upon conversion of convertible
     securities outstanding as of such date and (2) Artecon may continue to
     grant stock options in the ordinary course and consistent with past
     practice, provided that any such options shall be subject to Artecon's
     standard vesting schedule (but such options shall not vest more than 25%
     per year following the grant thereof) and in no event shall any such
     options contain any provisions pursuant to which the vesting of such
     options may or would be accelerated in any respect upon any change in
     control transaction or any other transaction, including without limitation
     the Merger, or any similar provision);

counsel, that such action is required in order for the Board to comply with its
fiduciary obligations to such company's securityholders under applicable law,
(B) prior to furnishing any such nonpublic information to, or entering into

     In connection with the Merger, Storage Dimensions will amend its
Certificate of Incorporation in order to: (i) change its name to "Artecon, Inc."
and (ii) designate a new Series A Preferred Stock, of which 2,494,159 shares
will be authorized. In addition, Storage Dimensions stockholders are being asked
to approve amendments to the Storage Dimensions Certificate of Incorporation to
(i) provide for a classified Board of Directors whereby the directors will be
separated into three classes, with members of each class serving for a three
year term; and (ii) provide that a director may not be removed from office
without cause except, until the third annual meeting of stockholders of Storage

outstanding voting stock of Storage Dimensions and by the affirmative vote of at
least 66 2/3% of the outstanding voting stock of Storage Dimensions thereafter.
The following is a summary of the provisions of the Certificate of Amendment to
the Storage Dimensions Certificate of Incorporation (the "Certificate of
Amendment"), as proposed to be amended as a result of the Merger and the
Certificate of Incorporation Amendments. Such summary is qualified in its
entirety by the Certificate of Amendment attached as Annex A to this Joint Proxy
Statement/Prospectus and is incorporated by reference herein.
 
     Name Change. Pursuant to the Certificate of Amendment, effective upon the
Effective Time, Storage Dimensions will change its name to "Artecon, Inc."
 
     Classified Board. Under the terms of the Certificate of Amendment,
following the Merger, the Storage Dimensions Board will be divided into three
classes, serving staggered terms of three years. Jason Sauey and Chong Sup Park
will serve as Class II directors, whose term will expire at the second Annual
Meeting following the Merger. W.R. Sauey, James Lambert and Brian Fitzgerald
will serve as Class III directors, whose term will expire at the third Annual
Meeting following the Merger. Two additional directors chosen by the Storage
Dimensions Board and the Artecon Board together, either before the Merger or
shortly thereafter, will serve as Class I directors, whose term will expire at
the first Annual Meeting following the Merger. Officers serve at the discretion
of Storage Dimensions' Board of Directors. See "MANAGEMENT OF STORAGE DIMENSIONS
AFTER THE MERGER."
 
     Removal of Directors. A director may not be removed from office without
cause under the Certificate of Amendment except, until the third annual meeting
of stockholders of Storage Dimensions following the
 
                                       68
<PAGE>   84
 
Merger, by the affirmative vote of at least 80% of the outstanding voting stock
of Storage Dimensions and by the affirmative vote of at least 66 2/3% of the
outstanding voting stock of Storage Dimensions thereafter.
 
     Storage Dimensions Preferred Stock. The Certificate of Amendment designates
a new Series A Preferred Stock of Storage Dimensions consisting of 2,494,159
shares (the "Series A Stock"). Each share of Series A Stock shall be
convertible, at the option of the holder, at any time after January 1, 1999,
into such number of fully paid and nonassessable shares of Storage Dimensions
Common Stock as is determined by dividing two dollars ($2.00) by the greater of
(a) $6.00 and (b) the average of the closing price of the Storage Dimensions
Common Stock during the 20 trading days ending on the date that is two days
prior to the date on which conversion is requested. Each share of Series A Stock
shall be converted automatically into fully paid and nonassessable shares of
Storage Dimensions Common Stock on the earlier of (a) the close of business on
the day on which the Storage Dimensions Board shall have duly and unanimously
adopted a resolution requesting such conversion, in which case the number of
shares of Storage Dimensions Common Stock issuable upon conversion of the Series
A Stock shall be determined by dividing two dollars ($2.00) by the average of
the closing price of the Storage Dimensions Common Stock during the 20 trading
days ending on the date that is two days prior to the date on which the Storage
Dimensions Board requests conversion; and (b) at the close of business on the
first business day following the date on which the average of the closing per
share sales price of the Storage Dimensions Common Stock as reported on the
Nasdaq National Market (or any other U.S. securities market or exchange on which
the Storage Dimensions Common Stock may trade) for 20 consecutive trading days
equals or exceeds nine dollars ($9.00) per share (the "Average Price"), in which
case the number of shares of Storage Dimensions Common Stock issuable upon
conversion of each share of Series A Stock shall be determined by dividing two
dollars ($2.00) by the Average Price. The maximum number of shares of Storage
Dimensions Common Stock issuable upon conversion of the Series A Stock being
issued in the Merger is approximately 831,000. Following the amendment of its
Certificate of Incorporation, Storage Dimensions will continue to have 7,505,841
shares of undesignated Preferred Stock. The Board of Directors has the authority
to issue the shares of Preferred Stock in one or more series and to fix the
rights, preferences, privileges and restrictions granted to or imposed upon any
unissued series of Preferred Stock and to fix the number of shares constituting
any series and the designations of such series, without any further vote or
action by the stockholders. Although it presently has no intention to do so, the
Storage Dimensions Board of Directors, without stockholder approval, may issue
additional Storage Dimensions Preferred Stock with voting and conversion rights
which could adversely affect the voting power of the holders of Storage
Dimensions Common Stock. The issuance of additional Storage Dimensions Preferred
Stock may have the effect of delaying, deferring or preventing a change in
control of Storage Dimensions.
 
     In the event of any liquidation, dissolution or winding up of Storage
Dimensions, the holders of the Series A Stock are entitled to receive, prior and
in preference to any distribution of any of the assets or surplus funds of
Storage Dimensions, an amount equal to two dollars ($2.00) per share (as
adjusted for any stock dividends, combinations or splits, reclassifications or
the like with respect to such shares) plus all accrued, accumulated or declared
but unpaid dividends on each share of Series A Stock held by such holders. After
payment to the holders of the Series A Stock of the amount described above, the
entire remaining assets and funds of Storage Dimensions legally available for
distribution will be distributed ratably among the holders of the Storage
Dimensions Common Stock in proportion to the number of shares then held by such
holders. A "liquidation" includes any merger in which the holders of Storage
Dimensions Common Stock no longer hold a majority of such stock or sale of
substantially all of Storage Dimensions assets.
 
     The shares of Series A Stock will be voted together with the Storage
Dimensions Common Stock as a single class at any annual or special meeting of
stockholders of Storage Dimensions following the Merger. The holders of each
share of Series A Stock shall be entitled to the number of votes equal to the
number of shares of Storage Dimensions Common Stock into which such share of
Series A Stock could be converted on the record date for the vote.

           STORAGE DIMENSIONS MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
     The following discussion of the financial condition and results of
operations of Storage Dimensions should be read in conjunction with the
consolidated financial statements and the related notes thereto included herein.
The discussion in this Joint Proxy Statement/Prospectus contains forward-looking
statements that involve risks and uncertainties. Storage Dimensions' actual
results could differ materially from those discussed in the forward-looking
statements. Factors that could cause or contribute to such differences include,
without limitation, those discussed in this section and the sections entitled
"Risk Factors," and "Storage Dimensions Business," as well as those discussed
elsewhere in this Joint Proxy Statement/Prospectus.
 
OVERVIEW
 
     Storage Dimensions was formed in late 1992 to acquire the assets of the
"Storage Dimensions" subsidiary of Maxtor (the "Predecessor") for an aggregate
of $21.4 million (the "Storage Acquisition"). The Storage Acquisition, which was
completed in December 1992, was financed through equity investments in Storage
Dimensions made by the Capital Partners Group by certain members of management
and by Maxtor. A portion of the purchase price was also funded through bank
borrowings and through a subordinated term loan in the principal amount of $4
million payable to Maxtor. The note payable to Maxtor was originally due
December 31, 1995 but the maturity date was extended to the earlier to occur of
the completion of Storage Dimension's initial public offering or May 10, 1997. A
portion of the proceeds from Storage Dimension's initial public offering was
used to repay the remaining balance due to Maxtor.
 
     Prior to the Storage Acquisition, the Predecessor was primarily engaged in
designing, manufacturing and selling high volume storage products that attached
to PCs and Macintosh computers and low-end servers. These desktop products
generally incorporated Maxtor disk drives. As part of its strategy to develop a
business that could successfully operate independently from Maxtor and would
generate higher gross margins, during 1992 the Predecessor began to sell RAID
products targeted at the enterprise storage markets. For the nine months ended
December 31, 1992, desktop and enterprise/OEM product sales represented 85.9%
and 14.1%, respectively, of total net sales. In furtherance of its long-term
strategy, the transition was accelerated following the Storage Acquisition such
that, in 1994 enterprise/OEM product sales represented a majority of total net
sales and, for the year ended December 31, 1997, enterprise/OEM product sales
represented substantially all of Storage Dimensions net sales. As the mix
shifted from desktop products to enterprise/OEM products, the gross margins
improved from 26.2% in 1993 to 37.3% in 1996, but declined to 35.9% in 1997.
Storage Dimensions does not expect sales of desktop products to represent a
material portion of its net sales in future periods.
 
     The transition from desktop storage to enterprise RAID storage products
required a significant investment in research and development, sales and
marketing, and operations. To implement this transition, Storage Dimensions
significantly enhanced its infrastructure and employee expertise during 1995,
1996 and 1997, and operating expenses increased from 30.4% of sales in 1994 to
39.2% in 1997. The largest single expense associated with this transition was
the staffing of a direct end-user sales organization starting in the third
quarter of 1994.
 
     The absorption of fixed manufacturing overhead suffered during the
transition from desktop to enterprise/OEM products as manufacturing volume
decreased and RAID systems required more sophisticated and time consuming
integration and test processes. The sale of the Storage Dimensions' Macintosh
product line in 1994 further reduced volume and exacerbated the unfavorable
overhead absorption situation. By the end of 1995 and continuing through 1996,
the higher manufacturing volumes of the Storage Dimensions' RAID enterprise/OEM
products resulted in greater overhead absorption and reductions in the per-unit
manufacturing costs of such products. Gains from this effect leveled off in
1997, so that at the end of 1997 Storage Dimensions still had significant excess
manufacturing capacity remaining. As a result, if manufacturing volumes were to
increase, the Storage Dimensions would expect to achieve further economies of
scale and lower per-unit manufacturing costs.

     Revenue from product sales is recognized upon shipment. Net sales reflect
the invoiced amount for goods shipped less reserves for estimated returns.
Storage Dimensions provides price protection to its distributors such that, if
Storage Dimensions reduces the price of its products, distributors are entitled
to a credit for the difference between the new, reduced price and the price they
previously paid for products which are held in the distributor's inventory at
the time of the price reduction. As a result, price reductions could have a
material adverse effect on results of operations, depending upon distributor
inventory levels at the time of the price reduction. In 1994, 1995, 1996 and
1997, Storage Dimensions issued approximately $161,000, $550,000, $840,000 and
$485,000, respectively, of credits in connection with such price protection.
 
     Storage Dimensions utilizes a direct sales force to penetrate major new
accounts, to create demand for its products, and to secure repeat business from
existing customers. Storage Dimensions also maintains reseller distribution
channels that facilitate procurement of Storage Dimensions' products by small
and medium-sized end-users, producing incremental revenues from its marketing,
sales and promotional efforts. In addition, certain large customers prefer to
source through the reseller channels as part of their overall network equipment
sourcing and integration strategy. Therefore, Storage Dimensions' resellers also
fulfill some large customer orders that were generated by Storage Dimensions'
direct sales force.
 
     After expanding its field sales force throughout 1997, Storage Dimensions
reevaluated the effectiveness of its field sales force strategy in early 1998.
As a result, five single-person sales offices in smaller geographic markets were
closed in order to focus resources in the major metropolitan areas where larger
sales offices are already established, and certain management positions in the
sales organization were eliminated. Storage Dimensions intends to use its
independent resellers to more efficiently serve the smaller geographic markets.
Storage Dimensions believes that this new structure will allow for future sales
growth while helping to control costs. Storage Dimensions intends to support and
expand as appropriate its direct sales force in key markets while seeking to
expand its reach into smaller markets through enhanced reseller arrangements.
Storage Dimensions believes it can continue to generate additional sales at
lower incremental selling costs. Storage Dimensions is prepared to expand its
field sales operations in these major areas to further leverage its current
investment.
 
     Storage Dimensions currently expects its revenues for the fiscal quarter
ending March 31, 1998 to be significantly less than its results of operations
for the fourth quarter of 1997 and for the first quarter of 1997. Storage
Dimensions attributes the decline to a combination of uncertainty in the
marketplace resulting from Storage Dimensions' announcement of the Merger in
late 1997 and continued sales force productivity issues.
 
     The following discussion and analysis has been prepared without giving
effect to the Merger. Should the Merger be completed, the business of Storage
Dimensions and Artecon will be combined and, accordingly, the historical
liquidity and results of operations of Storage Dimensions would not be
indicative of the Combined Company's future liquidity or operating results.

</TABLE>
 
     1997 COMPARED TO 1996
 
     Net Sales. Net sales decreased 1.4% to $71.3 million in 1997, compared to
$72.3 million during 1996. Sales of Enterprise/OEM products accounted for
virtually all of the 1997 revenue, as the shift away from older Desktop products
was completed. Revenues were essentially unchanged compared to the prior year
primarily due to pricing declines in the first half of 1997, slow growth in
sales force productivity throughout the year and a drop in revenue from sales to
Xerox, Storage Dimensions' primary OEM customer. Revenue from Xerox decreased
from approximately 13% of net revenue in 1996 to approximately 6% of net revenue
in 1997. The continued penetration into the emerging Windows-NT marketplace was
offset by declines in the Novell NetWare arena due to Novell's loss of market
share to Microsoft's Windows NT. Products first introduced in 1997 did not
account for significant growth.
 
     Gross Profit. Gross profit for 1997 was $25.6 million, or 35.9% of net
sales, compared to $27.0 million, or 37.3% of net sales in 1996. The decrease in
gross profit as a percentage of net sales in 1997 was primarily attributable to
inventory write downs brought about by rapid declines in the cost of disk drives
in the second quarter, and increased pricing pressure from competition. The
adverse effects of pricing pressures were partially offset by reductions in
material costs and a decline in the volume of relatively low margin OEM
business. Storage Dimensions' gross margin has been and will continue to be
affected by a variety of factors, including: competition; product configuration;
the mix of direct versus indirect sales; the mix of enterprise, OEM and desktop
products sold in any given period; the availability of new products and product
enhancements which tend to carry higher gross margins than older products; and
the cost and availability of components.
 
     Sales and Marketing. Sales and marketing expenses consist primarily of
salaries and commissions, advertising and promotional costs and customer service
and support expenses. Sales and marketing expenses for 1997 totaled $17.5
million, or 24.5% of net sales, compared to $14.1 million, or 19.5% of net sales
in 1996. The increase in absolute amount was caused largely by the expenses of
expanding the direct sales force and to a lesser extent from the costs of new
product introductions. The increase in sales and marketing expense as a
 
                                       72
<PAGE>   88
 
percentage of net sales in 1997 resulted from the slow increase in productivity
of the new sales representatives and the decline in OEM revenue. There can be no
assurance that an increase in these expenses will result in a proportional
increase in net sales and the sales and marketing expense as a percentage
revenue is expected to fluctuate in future periods.
 
     Research and Development. Research and development expenses consist
primarily of employee compensation, prototype expenses and fees paid to outside
consultants. To date no software development costs have been capitalized.
Research and development expenses for 1997 totaled $6.3 million, or 8.8% of net
sales, compared to $5.9 million, or 8.1% of net sales in 1996. The increase in
research and development spending in absolute amount during 1997 was primarily a
result of increased staffing levels necessary to support continued development
of RAID products, primarily for the RAIDPro product and clustering solutions.
The increase as a percentage of net sales was a result of the increase in the
level of research and engineering spending. Storage Dimensions believes that
significant investments in research and development will continue to be required
to remain competitive and expects that these expenditures will increase in
absolute dollars and fluctuate as a percentage of net sales in future periods.
 
     General and Administrative. General and administrative expenses consist
primarily of compensation expenses for employees performing the Storage
Dimension's administrative functions. General and administrative expenses for
1997 totaled $4.2 million, or 5.9% of net sales, compared to $3.8 million, or
5.3% of net sales in 1996. General and administrative expenses increased in
absolute amount primarily as a result of the additional costs associated with
operating as a public company and increased consulting costs.
 
     Advisory Fee. The advisory fees formerly consisted of amounts payable to
Capital Partners pursuant to the Advisory Agreement that was terminated in 1996.
Consequently, there were no fees in 1997 compared to fees of $729,000 in 1996.
The 1996 fees included a one-time payment of $360,000 made in connection with
the termination of the Advisory Agreement.
 
     Other Income (Expense), Net. Other income (expense), net consists primarily
of interest income on investments offset by interest payments on outstanding
debt. Other income (expense), net was a net expense of $68,000 in 1997 compared
to a net expense of $1,155,000 in 1996. The drop in the interest expense comes
from the investment of the proceeds from Storage Dimensions public offering in
the second quarter. Some interest expense continues to be recorded from the
expenses associated with maintaining Storage Dimensions' current but unused line
of credit.
 
     Income Taxes. Income tax expenses incurred in 1996 and 1997 consist of
federal alternative minimum taxes and California minimum franchise taxes for
state taxes and taxes paid outside the United States. In determining likelihood
of future realization of deferred tax assets, management considered various
factors including Storage Dimensions's past history of losses and variability in
quarterly results, and the significant competitive pressures in the industry in
which Storage Dimensions operates. See "RISK FACTORS -- History of Operating
Losses of Storage Dimensions; Potential Fluctuations in Quarterly Results." In
the opinion of management, based on these factors, as of December 31, 1997, it
was considered more likely then not that the gross deferred tax assets would not
be realized. Accordingly, at December 31, 1997, Storage Dimensions recorded a
full valuation allowance for these deferred tax assets. A future change in
Storage Dimensions's assessment of the likelihood of future realization of
deferred tax assets could result in a reduction of the valuation allowance, a
corresponding reduction in Storage Dimensions's income tax expense recorded for
financial statement purposes and a corresponding increase in net income. This
would not, however, result in a change in actual income taxes payable by Storage
Dimensions in any future period. See Note 5 of Notes to the Consolidated
Financial Statements.
 
     1996 COMPARED TO 1995
 
     Net Sales. Net sales increased 20.2% to $72.3 million in 1996, compared to
$60.2 million during 1995. Sales increased primarily due to a 33.1% increase to
$69.9 million for Enterprise/OEM products, reflecting the continued shift in
Storage Dimensions's product strategy toward these newer products.
Enterprise/OEM products accounted for 96.6% of net sales, up from 87.2% in 1995.
 
                                       73
<PAGE>   89
 
     Gross Profit. Gross profit for 1996 was $27.0 million, or 37.3% of net
sales, compared to $23.0 million, or 38.2% of net sales in 1995. The decrease in
gross profit as a percentage of net sales in 1996 was primarily attributable to
pricing pressures in the market for products using 4 gigabyte disk drives during
the first half of 1996, as well as a relative increase in OEM sales which
generally carry lower gross profit margins than enterprise products. The adverse
effects of these factors were partially offset by the overall increase in sales
of enterprise products which tend to carry higher gross margins, manufacturing
efficiencies resulting from the higher level of sales of enterprise/OEM products
and the elimination from Storage Dimensions's desktop product line of certain
lower-margin, commodity-like products.
 
     Sales and Marketing. Sales and marketing expenses for 1996 totaled $14.1
million, or 19.5% of net sales, compared to $13.3 million, or 22.2% of net sales
in 1995. Sales and marketing expense in 1996 in absolute amount was relatively
flat compared to 1995, as Storage Dimensions did not significantly increase its
sales staff during most of 1996. The decrease in sales and marketing expense as
a percentage of net sales in 1996 resulted from increased productivity of the
sales and marketing organization.
 
     Research and Development. Research and development expenses for 1996
totaled $5.9 million, or 8.1% of net sales, compared to $5.4 million, or 8.9% of
net sales in 1995. The increase in research and development spending in absolute
amount during 1996 was primarily a result of increased staffing levels necessary
to support continued development of RAID products.
 
     General and Administrative. General and administrative expenses for 1996
totaled $3.8 million, or 5.3% of net sales, compared to $3.4 million, or 5.6% of
net sales in 1995. General and administrative expenses increased in absolute
amount primarily as a result of consulting costs associated with strategic
planning activities.
 
     Advisory Fee. Advisory fees totaled $729,000, or 1.0% of net sales in 1996,
compared to $360,000, or 0.6% of net sales in 1995. The 1996 amount includes a
one-time payment of $360,000 made in connection with termination of the Advisory
Agreement.
 
     Other Income (Expense), Net. Other income (expense), net was an expense of
$1.2 million in 1996, up from an expense of $1.1 million in 1995. The difference
primarily represents a one-time charge relating to the refinancing of Storage
Dimensions's revolving line of credit during 1996.
 
     Income Taxes. Income tax expenses incurred in 1995 and 1996 were minimal as
a result of operating losses incurred and the carry forward of prior period
losses. These carry forwards were virtually exhausted as of December 31, 1996.
Remaining gross deferred tax assets of $1,695,000 at December 31, 1996 are
primarily attributable to differences between the financial accounting and tax
deductibility of certain items including inventory reserves, depreciation and
amortization, research and development credits and compensation accruals. In the
opinion of management, as of December 31, 1996, it was considered more likely
than not that the gross deferred tax assets would not be realized. Accordingly,
at December 31, 1996, Storage Dimensions recorded a full valuation allowance for
these deferred tax assets. See Note 5 of Notes to the Storage Dimensions
Consolidated Financial Statements.
 
     1995 COMPARED TO 1994
 
     Net Sales. Net sales decreased 1.7% to $60.2 million in 1995, compared to
$61.2 million during 1994. Sales decreased primarily due to a 63% decrease in
sales of desktop products, partially offset by a 30% increase in sales of
enterprise/OEM products. Enterprise/OEM products accounted for 87.2% of the net
sales in 1995, up from 65.5% of net sales in 1994.
 
     Gross Profit. Gross profit for 1995 was $23.0 million, or 38.2% of net
sales, compared to $19.2 million, or 31.4% of net sales in 1994. The increase in
gross profit as a percentage of net sales in 1995 was primarily attributable to
a favorable sales mix of higher-end enterprise systems included in
enterprise/OEM product revenues partially offset by an unfavorable mix in sales
of lower margin desktop products included in desktop product revenues in the
period.
 
                                       74
<PAGE>   90
 
     Sales and Marketing. Sales and marketing expenses for 1995 totaled $13.3
million, or 22.2% of net sales, compared to $10.7 million, or 17.4% of net sales
in 1994. Sales and marketing expenses increased in absolute amount and as a
percent of net sales in 1995 primarily as a result of Storage Dimensions'
efforts to build its sales and marketing organization to support the transition
from indirect to direct sales efforts.
 
     Research and Development. Research and development expenses for 1995
totaled $5.4 million, or 8.9% of net sales, compared to $4.3 million, or 7.1% of
net sales in 1994. The increase in research and development spending in both
absolute amount and as a percentage of net sales during 1995 was primarily a
result of development activities related to Storage Dimensions' RAID products.
 
     General and Administrative. General and administrative expenses for 1995
totaled $3.4 million, or 5.65% of net sales, compared to $3.3 million, or 5.4%
of net sales in 1994. General and administrative expenses in both absolute
amount and as a percentage of net sales were relatively flat from 1994 to 1995
as management responded to flat overall sales levels.
 
     Advisory Fee. Advisory fees totaled $360,000 and $362,000 in 1995 and 1994,
respectively, and constituted 0.6% of net sales in both years.
 
     Other Income (Expense), Net. Other income (expense), net was an expense of
$1.1 million in 1995, up from an expense of $983,000 in 1994. The increase in
1995 was primarily attributable to higher average loan balances during the year
as well as an increased interest rate on the loan payable to Maxtor. See
"Certain Transactions."
 
     Income Taxes. Income tax expenses incurred in 1994 and 1995 were minimal as
a result of operating losses incurred. Gross deferred tax assets of $2,259,000
at December 31, 1995 are primarily attributable to operating loss carryforwards
and differences between the financial accounting and tax deductibility of
certain items including inventory reserves, depreciation and amortization,
research and development credits and compensation accruals. In the opinion of
management, as of December 31, 1995, is was considered more likely than not that
the net deferred tax assets would not be realized. Accordingly, at December 31,
1995, Storage Dimensions recorded a full valuation allowance for these deferred
tax assets. See Note 5 of Notes to the Storage Dimensions Consolidated Financial
Statements.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     As of December 31, 1997, Storage Dimensions' working capital was $17.3
million, up from $2.5 million at December 31, 1996. The increased in working
capital was primarily attributable to the proceeds of Storage Dimensions'
initial public offering in 1997 offset by the repayment of short-term debt with
a portion of such proceeds and the effects of the operating losses in 1997. Net
accounts receivable increased slightly to $12.2 million at December 31, 1997,
compared to $11.9 million at December 31, 1996, as a result of slowness in
payments at year end. Inventories decreased to $5.6 million at December 31,
1997, from $6.3 million at December 31, 1996, primarily as a result of the
reduction in strategic supplies as the risk of shortages identified in late 1996
has abated. Accounts payable decreased to $4.0 million at December 31, 1997,
compared to $5.1 million at December 31, 1996 largely from the effects of
payment timing related to the increase of strategic inventories at the end of
1996.
 
     Storage Dimensions has an $11 million revolving line of credit expiring in
May 1998. The borrowings under the line of credit bear interest at the rate of
prime plus 0.75% (9.25% at December 31, 1997). Borrowings are secured by all
Storage Dimensions' assets. There were no borrowings outstanding under the line
of credit at December 31, 1997 and, as of such date, $11 million was available
for borrowings. There are no financial covenants in the line of credit.
 
     Storage Dimensions presently expects that current cash resources, together
with cash generated from operations should be sufficient to meet its operating
and capital requirements for the next twelve months. Storage Dimensions may,
however, need additional capital prior to that time. There can be no assurance
that additional capital will be available to Storage Dimensions on favorable
terms or at all.

                          STORAGE DIMENSIONS BUSINESS
 
     The discussion in this Joint Proxy Statement/Prospectus contains
forward-looking statements which involve risks and uncertainties. Storage
Dimensions' actual results could differ materially from those discussed in the
forward-looking statements. Factors that could cause or contribute to such
differences include, without limitation, those discussed in this section and the
sections entitled "Risk Factors," "Storage Dimensions' Management's Discussion
and Analysis of Financial Condition and Results of Operations" as well as those
discussed elsewhere in this Joint Proxy Statement/Prospectus.
 
     Storage Dimensions designs, manufactures, markets and supports
high-performance data storage systems for open systems network applications.
Open systems networks are comprised of equipment that conforms to industry
standards of interoperability. Storage Dimensions currently focuses on the
PC-LAN market by developing and marketing a broad family of disk and tape
storage systems that are designed to satisfy the high-performance,
fault-tolerance and high-availability (minimum downtime) requirements of its
customers while at the same time reducing life-cycle cost of ownership
(consisting of the purchase price of the equipment plus the cost of operating
this equipment over its life span). Storage Dimensions' products combine its
proprietary software with industry-standard hardware, such as disk drives, tape
drives and RAID controllers, which allows Storage Dimensions to leverage the
product development and manufacturing capabilities and efficiencies of industry
OEM manufacturers and to offer its customers products that take advantage of
what Storage Dimensions believes to be the best technology available. Storage
Dimensions' products have won numerous industry awards in product comparisons
and editorial reviews. As the leading independent supplier of high capacity RAID
storage systems for the PC-LAN market, Storage Dimensions believes that it is
well-positioned to take advantage of new opportunities being created by the
projected growth in the PC-LAN market, in particular the market for systems
utilizing Windows NT and NetWare.
 
INDUSTRY BACKGROUND
 
     The increased use of network computing to support business-critical
enterprise applications is fueling rapid demand growth for network disk storage
systems incorporating high performance, fault tolerance and high availability.
In addition, capacity requirements for network storage are accelerating, due to
the deployment of data-intensive new applications, such as relational databases,
decision support systems, the Internet and intranets, video/multimedia and
document management. Storage Dimensions believes that these factors will also
increase the demand for high-speed network tape backup, which provides
additional protection against data loss in the event of various system
malfunctions.
 
     RAID technology has facilitated this rapid expansion of network storage.
Traditionally, storage fault-tolerance was achieved using a technique called
mirroring, which involves the recording of duplicate data records on redundant
disks. Although effective, mirroring is an expensive means to protect against
data loss. In 1987, a team of researchers at the University of California at
Berkeley defined the concept of RAID, which utilizes parity algorithms to
achieve data redundancy at a significantly lower cost than mirroring. The
subsequent widespread implementation of RAID technology has removed a major
barrier to the proliferation of network computing by providing a cost-effective
method for achieving high storage reliability in enterprise network
applications.
 
     Historically, enterprise computing products have been categorized into
three general markets: (1) proprietary/mainframe systems; (2) RISC-based UNIX
multiuser systems; and (3) Intel-based local area networks ("PC-LAN market"). In
each of these markets, independent third-party suppliers have emerged to offer
advanced storage systems as alternatives to the storage systems offered by the
computer manufacturers themselves. To maximize their probability for success,
these independent storage system suppliers have generally focused on
opportunities within one of the three specific markets and tailored their
business, marketing and sales strategies accordingly. As a result, the markets
for storage systems are not monolithic in nature, but, rather, each of the three
markets is unique with its own principal competitors. Moreover, it is often
difficult for an industry participant to move from one market to another without
implementing major changes in business strategy that can undermine its
competitiveness in its original target market.
 
                                       76
<PAGE>   92
 
     Among the three principal enterprise computing markets, the PC-LAN market
is experiencing the fastest growth, according to IDC. The PC-LAN market emerged
in the late 1980s with the proliferation of desktop PCs and the development of
network operating systems (such as NetWare) that could efficiently tie PC's
together for resource and information sharing. This expansion is now being
fueled by the deployment of Intel-based servers using Pentium and Pentium Pro
microprocessors, which offer the computing power of RISC-based architectures at
a significantly lower cost. IDC projects that the U.S. market for PC-LAN storage
systems employing RAID technology will grow from $1.4 billion in 1995 to $6.0
billion in 2000, a compound annual growth rate of 34%. These trends are further
reinforced by the rapid adoption of the Windows NT operating system, which is
increasingly being used in mid-range database and application servers instead of
UNIX operating systems. IDC further projects that the U.S. market for PC-LAN
RAID storage systems running on Windows NT servers will grow from $0.3 billion
in 1995 to $2.1 billion in 2000, a compound annual growth rate of 50%.
 
     One of the key issues facing end-users of PC-LAN networks is the ongoing
cost of network maintenance and administration. For example, the Gartner Group
has estimated that the purchase price of hardware and software comprises only
20% of the three-year cost of network ownership. The remaining 80% of a
network's life-cycle cost of ownership consists of other associated expenses,
such as downtime, troubleshooting, repair, administration, training and user
support. With respect to network storage, there are many opportunities for the
storage system software to assist the enduser in lowering the life-cycle cost of
ownership, by providing useful functionality such as ease of installation, ease
of reconfiguration, robust management of failure conditions, remote monitoring
and alerting, diagnostic and troubleshooting support and ease of repair.
 
     Moreover, as enterprises adopt the latest generation networking
technologies to achieve higher levels of performance and reliability, complex
issues can arise surrounding integration of new system components into the
existing environment. For example, storage systems provided by server
manufacturers oftentimes are mounted internally to the server, are not
compatible with other manufacturers' servers, and cannot be readily migrated to
new servers or operating systems as requirements change. In such cases, the
adoption of new technologies, such as Pentium Pro-based servers and Windows NT,
can result in the premature, technological obsolescence of existing network
storage investments. On the other hand, these costs can be significantly reduced
by utilizing a server-independent storage system that is designed for use in a
heterogenous environment, supporting a range of servers and operating systems.
 
     Therefore, to achieve the objective of minimizing the life-cycle cost of
network storage, end-users need comprehensive storage solutions that incorporate
a number of features in addition to RAID fault-tolerance including: (1) high
availability with minimum system downtime (planned and unplanned); (2)
complementary high-performance tape backup solutions; (3) easy network storage
management and administration; (4) cross-platform support for heterogeneous
network hardware and environments; and (5) a comprehensive customer service and
support program. Many suppliers today offer only a portion of these features.
 
THE STORAGE DIMENSIONS SOLUTION
 
     Storage Dimensions currently focuses on the PC-LAN storage system market by
developing and marketing a comprehensive family of disk and tape storage systems
that are designed to satisfy the high-performance, fault-tolerance and
high-availability requirements of its customers while at the same time reducing
life-cycle cost of ownership. Storage Dimensions' solution combines its
proprietary software with industry-standard hardware, such as disk drives, tape
drives and RAID controllers, which allows Storage Dimensions to leverage the
product development and manufacturing capabilities and efficiencies of industry
OEM manufacturers and to offer its customers products that take advantage of
what Storage Dimensions believes to be the best technology available. Storage
Dimensions provides a complete, integrated solution for the PC-LAN storage
system market by offering the following features:
 
     High availability with minimum system downtime. Storage Dimensions'
SuperFlex and RAIDPRO disk storage products are engineered to provide redundancy
and fault-tolerance for critical components such as disk drives, power supplies
and cooling systems. Redundant components are easily serviced and hot-swappable,
to allow replacement by end-user service personnel while the system remains
online.
 
                                       77
<PAGE>   93
 
Moreover, the storage management software is designed to provide robust
management of failure conditions, remote monitoring, automatic notification of
failure events and online diagnostic and troubleshooting support.
 
     Complementary high-performance tape back-up solutions. To complement its
disk products, Storage Dimensions has engineered a family of high-speed,
high-reliability MEGAFLEX tape backup systems that are designed to address the
challenges of backing up increasing amounts of data in ever-shortening time
periods. These tape products are developed and tested to be easily integrated
and fully compatible with Storage Dimensions' storage systems. In addition,
these products are marketed on a stand-alone basis for use with other
manufacturers' disk storage systems.
 
     Easy network storage management and administration. Storage Dimensions
engineers its integration software to make its disk storage systems easy to
install, use, reconfigure, troubleshoot and administer. In addition, for the
NetWare and Windows NT environments, Storage Dimensions has developed
VantagePoint network storage management software that provides remote
monitoring, problem alerting, configuration documentation and performance
measurement of multiple storage systems from a single network console.
 
     Cross-platform support for heterogeneous network hardware. Storage
Dimensions designs external storage systems that are easily integrated with the
computer systems from a broad range of manufacturers. This cross-platform
capability affords significant economic advantages to end-users who have
heterogeneous and dynamic network environments by letting them standardize on a
single external storage system that can be easily reconfigured and redeployed as
requirements change, as compared to internal storage which is dedicated to a
specific manufacturer's server. Thus, as application needs evolve over time and
new generation servers are procured, Storage Dimensions' storage systems can be
readily migrated and resized to meet changing circumstances instead of being
prematurely obsoleted. In particular, Storage Dimensions' products are
engineered to support a seamless transition to Windows NT, without the need to
prematurely retire storage systems originally purchased to support NetWare or
other network operating systems. This provides important investment protection
in the network environment, where the capital expenditures on storage systems
are often equal to or greater than those spent on servers.
 
     A comprehensive customer service and support program. Storage Dimensions
also provides a complementary suite of service and support programs targeted at
lowering the maintenance cost of its storage systems, including an artificial
intelligence knowledge base that helps Storage Dimensions provide fast and
accurate diagnosis of technical problems, 24-hour access to technical support
and replacement parts, overnight replacement of failed components and
comprehensive site agreements.

     Storage Dimensions has developed, and will continue to enhance, its
existing extensive proprietary objectoriented software library. This library
enables Storage Dimensions to quickly integrate new hardware technologies to
bring new products to market in a rapid and cost-effective manner. Storage
Dimensions' software library supports a range of operating systems with a
minimum of additional software investment. For example, the advanced SuperFlex
4000 and 5000 products incorporate Storage Dimensions' proprietary RAIDFlex disk
array management software, which was specifically engineered to facilitate
cross-platform support and to require only a minimal portion of the underlying
code to be rewritten to adapt it to a new operating system. Similarly, Storage
Dimensions can adapt RAIDFlex software to manage a new generation RAID
controller by modifying only the section of the code that deals with
controller-specific algorithms and instruction sets. Storage Dimensions has a
U.S. patent application pending associated with the object-oriented, layered
architecture of its RAIDFlex array management software.
 
     Storage Dimensions' products utilize its proprietary software to
incorporate leading edge hardware features and capabilities relative to the
storage products offered by computer and server manufacturers, with design
features specifically engineered to minimize system downtime and to support easy
integration and
 
                                       80
<PAGE>   96
 
administration. For example, in May 1996, Storage Dimensions introduced the
SuperFlex 3000 with DGR. The DGR feature provides the ability to both expand and
reconfigure a RAID array without taking the system off-line, therefore
significantly reducing the time, effort and cost of managing RAID storage in
typical corporate network environments. SuperFlex with DGR won LAN Times' "Best
of LAN Times" (1997) and PC Week's "Analyst's Choice" (1996) awards. In
addition, Storage Dimensions became one of the first suppliers of network
storage systems to incorporate the new generation 9 gigabyte disk drives in
their products when it began shipping the first of such products in September
1996.
 
     Storage Dimensions' products have won numerous other awards, including:
INFOWorld's "Hot Products" (1997); LAN Times' "Best of LAN Times" (1996);
Computer Technology Review's "Editor's Choice" (1995); LAN Magazine's "Disk
Array Product of the Year" (1995); and Networld+Interop's "Best of Show" (1995).
 
PRODUCTS UNDER DEVELOPMENT
 
     Storage Dimensions intends to continue to design its mainstream products to
be compatible with both Windows NT and NetWare and selected products to be
compatible with Sun Solaris, IBM AIX and IBM OS/2 operating systems. In
particular, Storage Dimensions has focused, and expects to continue to focus,
its product development efforts on providing an easy, seamless transition to
Windows NT, without the need to obsolete or retire its prior investments in
Storage Dimensions' disk storage systems. As a result of Storage Dimensions'
efforts, most of Storage Dimensions' current disk and tape systems can be, and
Storage Dimensions intends that its future products will be able to be, migrated
between NetWare and Windows NT by simply installing Storage Dimensions' software
upgrade. This greatly simplifies the purchasing decision for customers in the
process of migrating to Windows NT and for those considering such a change in
the future.
 
     Storage Dimensions is currently completing the development of a clustered
storage system (SuperFlex 5500) that is expected to provide shared storage for a
cluster of network servers using a common operating system, with support for
automatic server failover and integrated tape backup. Storage Dimensions
believes that this clustering technology will be the basis for most storage
system architectures in the future and may provide significant differentiation
of Storage Dimensions in the market. Storage Dimensions is in Beta test with
several customers and expects to release this product in the second quarter of
1998. Storage Dimensions is also in Beta test on RAIDScape, its latest storage
management software program. RAIDScape will add new features and functionality
to the company's hardware products and provide customers an easy to use
graphical interface for managing their data storage devices. RAIDScape software
is a second generation software design based on over three years of development
and is written in a new "JAVA" based programming language. RAIDScape software
will be one of the key differentiating features for most of future Storage
Dimensions products.
 
     If Storage Dimensions is unable, for technological or other reasons, to
develop and introduce new products, in particular those for use with Windows NT,
in a timely manner in response to changing market conditions or customer
requirements, Storage Dimensions' business, operating results and financial
condition will be materially and adversely affected. In addition, there can also
be no assurance that Storage Dimensions will be successful in developing and
marketing any other products that respond to technological changes or evolving
industry standards, that Storage Dimensions will not experience difficulties
that could delay or prevent the successful development, introduction and
marketing of new products, or that its new products will adequately meet the
requirements of the marketplace and achieve market acceptance. See "-- Research
and Development."
 
CUSTOMERS AND APPLICATIONS
 
     Storage Dimensions markets its products primarily to large corporations,
institutions and government agencies for use in business-critical network server
applications that require high-reliability and non-stop operation. Storage
Dimensions has successfully placed major installations in a broad cross-section
of enterprises, encompassing a range of mainstream computing applications. In
1997, the Sun Financial Group accounted for approximately 10% of net sales. In
1996, Xerox Corporation accounted for approximately 13%
 
                                       81
<PAGE>   97
 
of total net sales. In 1995, Xerox accounted for approximately 11% of net sales
and TechData accounted for approximately 15% of net sales.
 
SALES AND MARKETING
 
     Storage Dimensions has implemented both a direct sales force and reseller
distribution channels in order to provide broad market penetration for its
products. Historically, Storage Dimensions marketed its products to end-users
through indirect reseller channels, including distributors, national computer
dealers, system integrators and VARs. In 1994, Storage Dimensions recruited and
deployed a direct field sales organization in order to more effectively pursue
large corporate and institutional sales opportunities in the United States. As
of December 31, 1997, the U.S. field sales organization consisted of 33 sales
professionals located in 15 geographical markets, including Boston, New York,
Washington D.C., Atlanta, Detroit, Chicago, Minneapolis, Dallas, Los Angeles,
Seattle, Tampa and the San Francisco Bay Area. Storage Dimensions utilizes its
direct sales force to penetrate major new accounts, to create demand for its
products and to secure repeat business from existing customers.
 
     Storage Dimensions also maintains indirect reseller channels to facilitate
procurement of Storage Dimensions' products by small and medium-sized end-users,
producing incremental revenues from its marketing, sales, and promotional
efforts that would otherwise be lost. In addition, certain large customers
prefer to source through the reseller channels as part of their overall network
equipment sourcing and integration strategy. Storage Dimensions has developed
pricing structures and field sales commission plans that are designed to
minimize sales channel conflicts and, as a result, is able to benefit from
significantly higher revenues than if only a direct sales model were deployed.
Storage Dimensions believes that this two-pronged sales strategy provides
meaningful competitive advantage over competitors who only provide products
directly to end-user customers. In a recent survey by LAN Magazine of the
largest 100 LAN resellers in the United States, Storage Dimensions was the
independent storage systems supplier mentioned most often as the preferred
provider of both disk array and tape backup products.
 
     With its domestic field sales organization and reseller distribution
channels in place, Storage Dimensions plans to generate additional sales at a
lower incremental cost by systematically expanding its field sales operation in
terms of both staffing and geographical presence. Internationally, Storage
Dimensions relies primarily on local distributors and maintains a sales and
service office in London, England to support its European distributors.
 
     To support its field sales organization, in 1995 Storage Dimensions
established a telemarketing department located in its Milpitas headquarters
location for processing new leads, qualifying new prospects, identifying active
projects and initiating appointments for field sales personnel to visit new
customers. Specifically, the telemarketing department focuses on identifying
large new sales opportunities and on facilitating a smooth hand-off of these
opportunities to the field sales personnel. The telemarketing department also
works closely with the marketing communications department to identify lead
sources and develop promotional programs that are most effective in developing
target opportunities.
 
     In 1995, Storage Dimensions implemented a trade-in program called
FlexCredit, which provides a significant trade-in credit on used disk and tape
drives, from both Storage Dimensions and other selected manufacturers, toward
the purchase of new products from Storage Dimensions. FlexCredit is another
example of Storage Dimensions' strategy to lower the cost of ownership of
network storage, and Storage Dimensions believes the program has been
instrumental in both retaining existing customers and capturing new ones.
Storage Dimensions maintains an active presence in the used storage equipment
market such that FlexCredit trade-ins can be recycled at nominal economic cost
to Storage Dimensions.
 
     After expanding its field sales force throughout 1997, Storage Dimensions
reevaluated the effectiveness of its field sales force strategy in early 1998.
As a result, five single-person sales offices in smaller geographic markets were
closed in order to focus resources in the major metropolitan areas where larger
sales offices are already established, and certain management positions in the
sales organization were eliminated. Storage Dimensions intends to use its
independent resellers to more efficiently serve the smaller geographic markets.
Storage Dimensions believes that this new structure will allow for future sales
growth while helping to control
 
                                       82
<PAGE>   98
 
costs. Storage Dimensions intends to support and expand as appropriate its
direct sales force in key markets while seeking to expand its reach into smaller
markets through enhanced reseller arrangements. Storage Dimensions believes it
can continue to generate additional sales at lower incremental selling costs.
Storage Dimensions is prepared to expand its field sales operations in these
major areas to further leverage its current investment.
 
CUSTOMER SERVICE AND SUPPORT
 
     Storage Dimensions believes that its ability to provide comprehensive,
proactive and responsive support is an important element in penetrating new
customer accounts and in securing repeat business from existing customers.
Storage Dimensions is committed to providing superior customer service and
support aimed at simplifying installation, reducing field failures, minimizing
system downtime and streamlining administration. For example, beginning in 1992,
Storage Dimensions undertook a major investment in an "artificial intelligence"
knowledge base, called TechConnect, to facilitate the timely and accurate
diagnosis of customer field problems and to enable Storage Dimensions to
recommend solutions with the highest probability of success, with reporting
capabilities to provide feedback on the most common problems experienced by end-
users of Storage Dimensions' products. Although accessed primarily by Storage
Dimensions technical support personnel, the TechConnect system is also
accessible by Storage Dimensions' customers 24 hours a day, through the
Internet, in the event any customer wishes to access solution documents
directly.
 
     Historically, service revenues have not comprised a significant portion of
Storage Dimensions' sales. In 1996, Storage Dimensions began an aggressive
program to develop value-added service contracts designed to achieve a lower
lifecycle cost of ownership for its customers. The following represent Storage
Dimensions' primary service programs currently available:
 
     7x24 Priority Service and Parts. For an annual site fee, Storage Dimensions
provides priority access to technical support personnel during business hours
and access within 20 minutes via a pager after hours. In addition, Storage
Dimensions provides replacement of failed parts 24 hours-a-day by
counter-to-counter air freight with courier delivery.
 
     Tape Maintenance. For an annual fee per tape drive, Storage Dimensions will
provide for overnight shipment of a replacement unit for drives that fail and
are not covered by Storage Dimensions' or manufacturer's standard warranty.
 
     TechAssist Emergency Off-Hours Support. For a one-time fee, Storage
Dimensions provides access to technical support personnel after hours to
customers who need emergency help, but have not contracted for the 7x24 Priority
Service.
 
     FlexGuard Premium Site Support. FlexGuard bundles optional services into
comprehensive site service and support arrangements to meet the special needs of
large organizations.
 
     In addition to the above services, Storage Dimensions provides telephone
support during business hours free of charge.
 
     Storage Dimensions supports and administers the pass-through of standard
warranties from its OEM component vendors which run from one to five years. In
addition, Storage Dimensions provides a three year warranty on the system as a
whole. A customer may also contract for an extended warranty from Storage
Dimensions on components whose factory warranty has expired. In the United
States, defective components are replaced overnight, in advance of the receipt
of the failed part, as a standard practice. Although to date Storage Dimensions'
suppliers of hardware components have covered the warranty costs associated with
such components, there can be no assurance that such manufacturers will continue
to be willing or able to cover such costs, and their failure to do so would
result in such costs being borne by Storage Dimensions. There can be no
assurance that warranty costs to Storage Dimensions will not be significant in
the future, which could have a material adverse effect on Storage Dimensions'
business, operating results or financial condition.

RESEARCH AND DEVELOPMENT
 
     To date, Storage Dimensions has made substantial investments in research
and development, particularly in the areas of fault-tolerant RAID systems
integration and storage management software. Storage Dimensions' solution
combines its proprietary software and industry-standard hardware to produce
integrated RAID fault-tolerant storage solutions, with companion
high-performance tape backup. Storage Dimensions has developed an extensive,
object-oriented software library which it uses to quickly integrate new hardware
products into its storage systems. Storage Dimensions' strategy is to continue
to expand its software library by adding new features and functionality in an
incremental manner, building on its earlier investments, and to leverage this
library to bring new products and features to market quickly.
 
     Storage Dimensions' engineering design teams work cross-functionally with
marketing managers, applications engineers and customers to develop products and
product enhancements. Computer input/output standards are maintained and an
extensive disk drive and controller board qualification program monitors
industry-standard components to ensure the quality and performance when
integrated into Storage Dimensions' storage system products. Storage Dimensions
also strives to develop and maintain close relationships with key suppliers of
storage system components and technologies, such as American Megatrends, Western
Digital, Fujitu, ATL, Exabyte, Cheyenne, Mylex, Seagate, Qualix and Quantum,
which Storage Dimensions believes enables it to quickly introduce new products
that incorporate the latest technological advances.
 
     Storage Dimensions' expenses for research and development for fiscal years
1995, 1996 and 1997 were $5.4 million, $5.9 million and $6.3 million,
respectively. As of December 31, 1997, Storage Dimensions had 37 regular
full-time employees engaged in research and development activities, of which 16
were specifically focused on software development, test and qualification.
 
     The network storage system market is characterized by rapid technological
change, changing customer needs, frequent new product introductions and evolving
industry standards. The introduction of products embodying new technologies and
increased storage capacities and the emergence of new industry standards could
render Storage Dimensions' existing products obsolete and unmarketable. Storage
Dimensions' future success will depend upon its ability to develop and to
introduce new products with increasing storage capabilities (including new
software releases and enhancements) on a timely basis that keep pace with
technological developments and emerging industry standards and address the
increasingly sophisticated needs of its customers. There can be no assurance
that Storage Dimensions will be successful in developing and marketing any new
products that respond to technological changes or evolving industry standards,
that Storage Dimensions will not experience difficulties that could delay or
prevent the successful development, introduction and marketing of new products,
or that its new products will adequately meet the requirements of the
marketplace and achieve market acceptance. In addition, network storage system
products like those offered by Storage Dimensions may contain undetected
software errors or failures when first introduced or as new versions are
released. There can be no assurance that, despite testing by Storage Dimensions
and by current and potential customers, errors will not be found in new products
after commencement of commercial shipments, resulting in a loss of or delay in
market acceptance, which could have a material adverse effect on Storage
Dimensions' business, operating results or financial condition.
 
MANUFACTURING
 
     Storage Dimensions' manufacturing operations, located in Milpitas,
California, consist primarily of assembly and integration of Storage Dimensions'
proprietary software and enclosures with industry-standard components, such as
disk drives, tape drives, and RAID controllers, from its suppliers. The
assembled units are then subjected to a systems-level test to ensure performance
to specification in the anticipated end-user computing environment. Storage
Dimensions' manufacturing operations have been ISO 9002 certified, an
international quality standard. Storage Dimensions strives to develop close
relationships with its suppliers, exchanging critical information and
implementing joint corrective action programs to maximize the quality of its
components, to reduce costs and inventory investments and to create flexibility
for rapid capacity expansion when required. Storage Dimensions believes that its
current facilities and capital equipment will be adequate to meet its
manufacturing needs in the foreseeable future.
 
                                       84
<PAGE>   100
 
     Storage Dimensions relies upon a limited number of suppliers of several key
components utilized in the assembly of Storage Dimensions' products. For
example, Storage Dimensions purchases disk drives primarily from Seagate, DLT
tape drives exclusively from Quantum and DGR RAID controllers exclusively from
American Megatrends. Storage Dimensions' reliance on its suppliers involves
several risks, including: an inadequate supply of required components; price
increases; late deliveries; and poor component quality. These risks are
particularly significant with respect to suppliers of disk drives because, in
order to meet product performance requirements, Storage Dimensions must obtain
disk drives with extremely high quality and capacity. In addition, there is
currently a significant market demand for disk drives, tape drives and RAID
controllers, and from time to time Storage Dimensions may experience component
shortages, selective supply allocations and increased prices of such components.
Although to date Storage Dimensions has been able to purchase its requirements
of such components, there can be no assurance that Storage Dimensions will be
able to obtain its full requirements of such components in the future or that
prices of such components will not increase. In addition, there can be no
assurance that problems with respect to yield and quality of such components and
timeliness of deliveries will not occur. Disruption or termination of the supply
of these components could delay shipments of Storage Dimensions' products and
could have a material adverse effect on Storage Dimensions' business, operating
results or financial condition. Such delays could also damage relationships with
current and prospective customers. In addition, in the past, due to Storage
Dimensions' quality requirements, Storage Dimensions has experienced delays in
the shipments of its new products principally due to an inability to qualify
component parts from disk drive manufacturers and other suppliers, resulting in
delay or loss of product sales. Storage Dimensions has currently qualified disk
drives manufactured by Seagate, tape drives from Quantum, and RAID controllers
from Mylex and American Megatrends. Although these delays in the past have not
had a material adverse effect upon Storage Dimensions' business, operating
results or financial condition, there can be no assurance that in the future any
such delays would not have such a material adverse effect.
 
COMPETITION
 
     The network storage system market is intensely competitive. Storage
Dimensions competes primarily in the PC-LAN storage systems market and
experiences the greatest competition from traditional suppliers of PC-LAN
network servers, such as Compaq, Hewlett-Packard and IBM, who market storage
systems as part of their complete computer systems. Storage Dimensions also
competes against independent storage system suppliers to the PC-LAN server
market, including DEC Storage Works, MTI Technology, Procom Technology, Inc. and
StreamLogic Corporation. In addition, providers of storage for the mainframe or
UNIX-based markets, such as Auspex Systems, Inc., Data General Corporation, EMC
Corporation, Network Appliance, Inc., Storage Computer, Inc. and Symbios Logic,
Inc. could develop and market products that address the PC-LAN storage systems
market, and in particular Windows NT applications. Many of Storage Dimensions'
current and potential competitors have significantly greater financial,
technical, marketing, purchasing and other resources than Storage Dimensions,
and as a result, may be able to respond more quickly to new or emerging
technologies and changes in customer requirements, to devote greater resources
to the development, promotion and sale of products than can Storage Dimensions,
or to deliver competitive products at a lower end-user price. Storage Dimensions
also expects that competition will increase as a result of industry
consolidations. Current and potential competitors have established or may
establish cooperative relationships among themselves or with third parties to
increase the ability of their products to address the needs of Storage
Dimensions' prospective customers. Accordingly, it is possible that new
competitors or alliances among competitors may emerge and rapidly acquire
significant market share. Increased competition is likely to result in price
reductions, reduced operating margins and loss of market share, any of which
could have a material adverse effect on Storage Dimensions' business, operating
results or financial condition.
 
     Storage Dimensions believes that the principal competitive factors
affecting its market include: fault-tolerant reliability, performance, ease of
use, scalability, configurability, price and customer service and support. There
can be no assurance that Storage Dimensions will be able to successfully
incorporate these factors into its products and to compete against current or
future competitors or that competitive pressures faced by Storage Dimensions
will not materially and adversely affect its business, operating results or
financial condition.

PROPRIETARY TECHNOLOGY AND INTELLECTUAL PROPERTY
 
     Storage Dimensions' success depends significantly upon its proprietary
technology. Storage Dimensions currently relies on a combination of copyright
and trademark laws, trade secrets, confidentiality agreements and contractual
provisions to protect its proprietary rights. Storage Dimensions seeks to
protect its software, documentation and other written materials under trade
secret and copyright laws, which afford only limited protection. Storage
Dimensions has registered its Storage Dimensions and LANStor trademarks and will
continue to evaluate the registration of additional trademarks as appropriate.
Storage Dimensions generally enters into confidentiality agreements with its
employees and with key vendors and suppliers. Storage Dimensions currently has
one U.S. patent application pending associated with the object-oriented layered
architecture of its RAIDFlex array management software. There can be no
assurance that this patent will eventually be issued, that Storage Dimensions
will develop proprietary products or technologies that are patentable, that any
patent issued in the future will provide Storage Dimensions with any competitive
advantages or will not be challenged by third parties, or that the patents of
others will not have a material adverse effect on Storage Dimensions' ability to
do business. Storage Dimensions believes that the rapidly changing technology in
the computer storage industry makes Storage Dimensions' success dependent more
on the technical competence and creative skills of its personnel than on any
patents it may be able to obtain.
 
     There has also been substantial litigation in the computer industry
regarding intellectual property rights, and litigation may be necessary to
protect Storage Dimensions' proprietary technology. Storage Dimensions has from
time to time received claims that it is infringing third parties' intellectual
property rights, and there can be no assurance that third parties will not in
the future claim infringement by Storage Dimensions with respect to current or
future products, trademarks or other proprietary rights. Storage Dimensions
expects that companies in the storage system market will increasingly be subject
to infringement claims as the number of products and competitors in Storage
Dimensions' target markets grows. Any such claims or litigation may be
time-consuming and costly, cause product shipment delays, require Storage
Dimensions to redesign its products or require Storage Dimensions to enter into
royalty or licensing agreements, any of which could have a material adverse
effect on Storage Dimensions' business, operating results or financial
condition. Despite Storage Dimensions' efforts to protect its proprietary
rights, unauthorized parties may attempt to copy aspects of Storage Dimensions'
products or to obtain and use information that Storage Dimensions regards as
proprietary. In addition, the laws of some foreign countries do not protect
proprietary rights to as great an extent as do the laws of the United States.
There can be no assurance that Storage Dimensions' means of protecting its
proprietary rights will be adequate or that Storage Dimensions' competitors will
not independently develop similar technology, duplicate Storage Dimensions'
products or design around patents issued to Storage Dimensions or other
intellectual property rights of Storage Dimensions.
 
EMPLOYEES
 
     As of December 31, 1997, Storage Dimensions had a total of 219 regular
full-time employees, of which 37 were engaged in engineering, research and
development; 102 in marketing, sales, and customer support; 51 in manufacturing;
and 29 in general management and administration. In addition, Storage Dimensions
had a total of 5 part-time and 12 temporary employees as of December 31, 1997.
None of Storage Dimensions' employees is represented by a labor union.
 
     Storage Dimensions' future performance depends in significant part upon the
continued service of its key technical and senior management personnel. Storage
Dimensions provides incentives such as salary, benefits and option grants (which
are typically subject to vesting over four years) to attract and retain
qualified employees. The loss of the services of one or more of Storage
Dimensions' officers or other key employees could have a material adverse effect
on Storage Dimensions' business, operating results or financial condition.
Storage Dimensions' future success also depends on its continuing ability to
attract and retain highly qualified technical and management personnel.
Competition for such personnel is intense, and there can be no assurance that
Storage Dimensions can retain its key technical and management employees or that
it can attract, assimilate or retain other highly qualified technical and
management personnel in the future.

FACILITIES
 
     Storage Dimensions' principal administrative, sales, marketing,
manufacturing and research and development facility is located in approximately
80,000 square feet of space in Milpitas, California. This facility is leased
through December 6, 1998. Storage Dimensions leases other sales offices
throughout the U.S., as well as a European operations site in London, U.K.
Storage Dimensions believes that its existing facilities are adequate for its
current needs.
 
LEGAL PROCEEDINGS
 
     Storage Dimensions is not a party to any material legal proceedings.

EMPLOYEE STOCK PLANS
 
     1993 STOCK OPTION PLAN
 
     Storage Dimensions' 1993 Stock Option Plan (the "1993 Option Plan"), which
provides for the grant of 555,555 shares of Storage Dimensions Common Stock, was
approved by the Storage Dimensions Board and stockholders on June 11, 1993. As
of December 31, 1997, options to purchase 360,580 shares were outstanding under
the 1993 Option Plan and 71,188 shares of Storage Dimensions Common Stock
remained available for issuance under the 1993 Option Plan. The terms of the
1993 Option Plan are substantially similar to those of the 1996 Stock Option
Plan described below. Effective January 1998, the 1993 Option Plan was amended
to provide that all outstanding options granted under the 1993 Option Plan (but
not any options granted in the future) will become fully vested and exercisable
upon completion of the Merger.
 
     1996 STOCK OPTION PLAN
 
     Storage Dimensions' 1996 Stock Option Plan (the "1996 Option Plan")
provides for the granting to employees and consultants of nonstatutory stock
options. The 1996 Option Plan was approved by the Board of Directors in December
1996 and by the stockholders in January 1997. A total of 1,000,000 shares of
Storage Dimensions Common Stock was originally reserved for issuance pursuant to
the 1996 Option Plan. As of December 31, 1997, options to purchase 805,831
shares of Storage Dimensions Common Stock were outstanding under the 1996 Option
Plan and 194,169 shares of Storage Dimensions Common Stock remained available
for issuance under the 1996 Option Plan. At the Storage Dimensions Special
Meeting, Storage Dimensions stockholders are being asked to approve an amendment
to the 1996 Option Plan in order to increase the number of shares issuable
thereunder to 3,000,000. See "ADDITIONAL MATTERS FOR CONSIDERATION FOR STORAGE
DIMENSIONS STOCKHOLDERS -- Amendment to 1996 Stock Option Plan."
 
     1996 EMPLOYEE STOCK PURCHASE PLAN
 
     Storage Dimensions' 1996 Employee Stock Purchase Plan (the "Purchase Plan")
was approved by the Storage Dimensions Board in December 1996 and by the
stockholders in January 1997. A total of 200,000 shares of Storage Dimensions
Common Stock was originally reserved for issuance under the Purchase
 
                                       89
<PAGE>   105
 
Plan. As of December 31, 1997, 47,253 shares of Storage Dimensions Common Stock
had been purchased under the Purchase Plan and 152,747 shares of Storage
Dimensions Common Stock remained available for purchase under the Purchase Plan.
At the Storage Dimensions Special Meeting, Storage Dimensions stockholders will
be asked to consider and approve an amendment to the Purchase Plan to increase
the number of shares of Storage Dimensions Common Stock issuable thereunder to
400,000. See "ADDITIONAL MATTERS FOR CONSIDERATION BY STORAGE DIMENSIONS'
STOCKHOLDERS -- Approval of Amendment to 1996 Employee Stock Purchase Plan."
 
401(k) PLAN
 
     Storage Dimensions has a 401(k) Plan, pursuant to which eligible employees
may elect to reduce their current salary by up to the statutorily prescribed
annual limit ($10,000 in 1998) and have the amount of such reduction contributed
to the 401(k) Plan. Storage Dimensions matches employee contributions to the
401(k) Plan at the rate of 50% of the employee's contribution up to a specified
limit. The 401(k) Plan is intended to qualify under Section 401 of the Code so
that contributions by participants to the 401(k) Plan, and income earned on plan
contributions, are not taxable to participants until withdrawn from the 401(k)
Plan.
 
SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE
 
     Section 16(a) of the Exchange Act requires Storage Dimensions' directors
and executive officers, and persons who own more than ten percent of a
registered class of Storage Dimensions' equity securities, to file with the SEC
initial reports of ownership and reports of changes in ownership of Storage
Dimensions Common Stock and other equity securities of Storage Dimensions.
Officers, directors and greater than ten percent stockholders are required by
the SEC regulation to furnish Storage Dimensions with copies of all Section
16(a) forms they file.
 
     To Storage Dimensions' knowledge, based solely on a review of the copies of
such reports furnished to Storage Dimensions and written representations that no
other reports were required, during the year ended December 31, 1997, all
Section 16(a) filing requirements applicable to its officers, directors and
greater than ten percent beneficial owners were complied with.
 
      CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS OF STORAGE DIMENSIONS
 
     Maxtor Promissory Note. In connection with the Storage Acquisition, Storage
Dimensions issued to Maxtor Corporation ("Maxtor") a promissory note in the
original principal amount of $4 million (the "Maxtor Note"). The Maxtor Note
bears interest at the rate of 8% per annum during the first year, 10% per annum
during the second year and 12% per annum for the remaining term. The Maxtor Note
was originally due on December 26, 1995 but the due date was subsequently
extended to the earlier to occur of the completion of Storage Dimensions'
initial public offering or May 10, 1997. During 1994, 1995 and 1996, Storage
Dimensions paid to Maxtor $400,000, $482,042 and $469,377, respectively, in
interest payments under the Maxtor Note. Storage Dimensions also paid $400,000
of principal in the third quarter of 1996 under the Maxtor Note. Storage
Dimensions paid the remaining outstanding principal together with unpaid
interest with a portion of the proceeds of its initial public offering. In
addition, during 1994 and 1995, Storage Dimensions purchased goods (principally
rigid magnetic and optical disk drives) from Maxtor and its affiliates totaling
$1.4 million and $69,000, respectively. Storage Dimensions did not purchase any
goods from Maxtor during 1996 or 1997.
 
     Capital Partners Agreements. In connection with the Storage Acquisition in
December 1992, Storage Dimensions entered into a certain advisory agreement with
Capital Partners. Capital Partners, together with its affiliates, is the holder
of a majority of Storage Dimensions' outstanding voting stock. Messrs.
Fitzgerald and Gebauer, current directors of Storage Dimensions, are also
officers of Capital Partners. During 1994, 1995 and 1996, Storage Dimensions
paid to Capital Partners $362,000, $360,000 and $729,000, respectively, pursuant
to such advisory agreement. The 1996 amount includes a one-time payment of
$360,000 paid by Storage Dimensions in connection with termination of the
advisory agreement by mutual agreement in December 1996.
 
                                       90
<PAGE>   106
 
     In addition, in connection with the proposed Merger Capital Partners has
entered into a standstill agreement with Storage Dimensions pursuant to which it
has agreed not to purchase additional shares of Storage Dimensions Common Stock,
with certain exceptions, until the earlier of five years from the closing of the
Merger or such time as Capital Partners no longer holds 5% of the outstanding
Storage Dimensions Common Stock. See "OTHER AGREEMENTS -- Standstill Agreement."
 
     Executive Officer Loans. In 1996, Storage Dimensions loaned David Bultman,
its Senior Vice President of Engineering at the time, amounts totaling $90,000.
Mr. Bultman is no longer employed with Storage Dimensions. The remaining balance
of Mr. Bultman's loan was $21,284 at December 31, 1997.
 
     Severance Agreements. In connection with the Merger, Storage Dimensions and
each of David Eeg, President and Chief Executive Officer, and Robert Bylin,
Chief Financial Officer of Storage Dimensions, amended the employment agreements
of such persons to provide certain severance benefits upon termination of their
relationship with Storage Dimensions.
 
     With respect to Mr. Eeg, upon termination of his status as a full time
employee or consultant of Storage Dimensions at either his option or that of
Storage Dimensions, Mr. Eeg shall receive severance payments equal to 66 weeks
of his regular salary, which shall be paid over such period. In addition, Mr.
Eeg's stock options granted under Storage Dimensions stock option plans have
been amended to provide that such options may be exercised for a period of two
years from the date of termination of his status as a full-time employee or
consultant of Storage Dimensions.
 
     With respect to Mr. Bylin, upon termination of his status as a full time
employee or consultant of Storage Dimensions at either his option or the option
of Storage Dimensions, Mr. Bylin shall receive severance payments equal to 47
weeks of his regular salary, which shall be paid over such period. In addition,
Mr. Bylin's stock options granted under Storage Dimensions stock option plans
have been amended to provide that such stock options may be exercised for a
period of one year from the date of termination of his status as a full-time
employee or consultant of Storage Dimensions under certain circumstances.
 
     In addition, both of such employment agreements, as amended, provide that
neither Mr. Eeg nor Mr. Bylin will compete with Storage Dimensions for the
remaining period of service by Messrs. Eeg and Bylin and during the time
severance payments are being made to them by Storage Dimensions.
 
     All future transactions, including loans, between Storage Dimensions and
its officers, directors and principal stockholders and their affiliates will be
approved by a majority of the Board of Directors, including a majority of the
independent and disinterested directors of the Board of Directors, and will be
on terms no less favorable to Storage Dimensions than could be obtained from
unaffiliated third parties.

                ARTECON MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                 FINANCIAL CONDITION AND RESULTS OF OPERATIONS
 
     The following discussion contains forward-looking statements that involve
risks and uncertainties. Artecon's and the Combined Company's actual results
could differ materially from those discussed below. Factors that could cause or
contribute to such differences include, but are not limited to, those discussed
in the sections entitled "Risk Factors," and "Artecon's Business," as well as
those discussed elsewhere in this Joint Proxy Statement/Prospectus.
 
OVERVIEW
 
     Artecon designs, manufactures, markets and supports a broad range of
scalable, fully integrated data storage products for the open-systems computing
environment. Artecon has established itself as a leader in the design,
manufacture and sale of third-party mass storage and enhancement products in the
Sun Microsystems ("Sun") and UNIX markets, offering both host-attached and
network-attached storage solutions for a broad range of customers. Artecon's
enterprise storage product line includes scalable RAID systems which allow users
to grow modularly from a single mass storage device to over ten terabytes
("10TB") of rack-mounted, fault-tolerant mass storage, thereby meeting the
capacity and performance needs of a wide range of customers while protecting and
maintaining customer investment. Artecon's telecommunications infrastructure
storage products represent what Artecon believes is the industry's only fully
NEBS-certified, multi-terabyte solution for high-end, application-specific needs
of telecommunications and government customers using commercial off-the-shelf
("COTS") workstation technology. Artecon also markets rack-mount solutions for
COTS workstations and servers and provides systems integration and a variety of
other service and support programs.
 
     Artecon was founded in 1984 in Carlsbad California as a supplier and
systems integrator of value added computer products. In 1990, Artecon began
research and development to design and manufacture its own proprietary data
storage products. In 1992, Artecon introduced its Lynx product line of storage
solutions and in 1994 Artecon introduced its Sphinx product line. Responding to
the need for cost-efficient, high quality mass storage solutions in the
telecommunications industry, in 1996, Artecon formed its TeleCom Division to
design, manufacture market and support fully integrated telecommunications
storage products, services and solutions.
 
     In August 1997, Artecon acquired Falcon Systems, Inc. ("Falcon"), a
network-attached storage server integrator and storage peripherals reseller (the
"Falcon Acquisition"). The Falcon Acquisition enabled Artecon to achieve several
important strategic objectives, including the acquisition of Artecon's
AerREAL(TM) real-time specialized file server software and other complementary
products to better serve Artecon's existing customers, the expansion of
Artecon's customer base in the UNIX, Windows NT and Windows 95 markets and a
significant expansion of Artecon's revenue base. The acquisition was accounted
for as a purchase and accordingly, the results of operations of Falcon from the
closing date of the acquisition forward have been included in Artecon's
consolidated financial statements dated December 31, 1997 and for the nine-month
period then ended.
 
     Artecon markets and distributes its products services through its direct
sales force employed in 11 domestic sales and support offices and 6 overseas
sales offices located in Japan, France, England and the Netherlands. In
addition, Artecon utilizes an extensive domestic and foreign reseller
distribution channel to market and distribute its products and services. Artecon
believes that such a diverse channel strategy results in the greatest
penetration of the market and enables it to effectively and efficiently
penetrate major accounts while at the same time leveraging its distribution
network into vertical markets. Artecon believes that the direct customer contact
resulting from the use of its own internal sales force provides it with
invaluable market feedback and the ability to tailor its products and
high-quality technical support services to enhance customer satisfaction and
loyalty. Artecon generates revenue from the sales of products and services.
Revenue from product sales is recognized upon shipment. Revenue generated from
service contracts is recognized ratably over the term of the contract. Operating
expenses consist primarily of rent, payroll, commissions, other selling and
administrative expenses and research and development costs and are recognized in
the period incurred.
 
     Artecon currently expects its revenues for the fiscal quarter ending March
31, 1998 to be significantly less than its results of operations for the quarter
ended December 31, 1997. Artecon attributes the decline
 
                                       92
<PAGE>   108
 
primarily to post-holiday seasonal sales declines and uncertainty in the
marketplace resulting from the announcement of the Merger in late 1997.
 
RESULTS OF OPERATIONS
 
     NINE MONTHS ENDED DECEMBER 31, 1997 COMPARED TO NINE MONTHS ENDED DECEMBER
31, 1996
 
     Net Revenues. Net revenues reflect the invoiced amounts for products
shipped less reserves for estimated returns. Net revenues for the nine months
ended December 31, 1997 were $52.6 million compared to $42.4 million for the
nine months ended December 31, 1996, an increase of approximately 24.1%. Such
increase in net revenues was primarily attributable to the Falcon Acquisition in
August 1997. Net revenues attributable to sales of Falcon products by Artecon
from August 21, 1997, the date of the Falcon Acquisition, to December 31, 1997
were approximately $12.6 million. Net revenues for the nine months ended
December 31, 1997 attributable to sales of Artecon products were $40.0 million,
compared to $42.4 million for the nine month period ended December 31, 1996. The
decrease in net revenues from sales of Artecon products for the nine months
ended December 31, 1997 compared to the same period for 1996 was the result of
decreased sales to a single customer in 1997. Sales to such customer amounted to
approximately $0.3 million and $12.8 million during the nine months ended
December 31, 1997 and December 31, 1996, respectively. Sales to this customer
prior to 1996 were not significant. Future sales to this customer are not
expected to be significant.
 
     Gross Margin. Gross margin for the nine months ended December 31, 1997 was
$14.9 million, or 28.3% of net revenues, compared to $9.2 million for the nine
months ended December 31, 1996, or 21.7% of net revenues. The increase in gross
margin as a percent of net revenues for the nine months ended December 31, 1997
compared to the nine months ended December 31, 1996 was due primarily to an
increase in sales of Artecon's higher margin LynxRAID and Sphinx product lines,
as well as a reduction in product costs resulting, in part, from increased
efficiencies in product design. The gross margin derived from sales of Falcon
products during the nine months ended December 31, 1997 was approximately $3.3
million, or 26.2% of net revenues.
 
     Selling, General and Administrative Expenses. Selling, general and
administrative expenses are comprised primarily of salaries, and commissions,
marketing costs and overhead costs associated with Artecon's finance and support
staff. Selling, general and administrative expenses increased to $10.4 million,
or 19.8% of net revenues for the nine months ended December 31, 1997, from $6.9
million, or 16.3% of net revenues, for the nine months ended December 31, 1996.
The increase in selling, general and administrative expenses during the nine
months ended December 31, 1997 was attributable primarily to the increase in
Artecon's sales and marketing force resulting from the Falcon Acquisition.
 
     Research and Development Expenses. Research and development expenses are
comprised primarily of prototype expenses, salaries for employees directly
engaged in research and other costs associated with product development.
Research and development expenses for the nine months ended December 31, 1997
increased to $2.3 million, or 4.4% of net revenues, from $1.5 million, or 3.5%
of net revenues during the nine months ended December 31, 1996. The increase in
research and development expenses is attributable to Artecon's continued
development of new products.
 
     Total Other Expense. Total other expense is comprised of interest, taxes
and other expenses, if any, relating to such periods presented. Total other
expense for the nine months ended December 31, 1997 was $727,000 compared to
total other expense of $209,000 for the nine months ended December 31, 1996. The
increase in total other expense was attributable primarily to interest payments
made on the promissory note issued by Artecon in connection with the Falcon
Acquisition and on increased borrowings under Artecon's credit line.
 
     YEAR ENDED MARCH 29, 1997 COMPARED TO YEAR ENDED MARCH 30, 1996
 
     Net Revenues. Artecon's net revenues for the year ended March 29, 1997 ("FY
1997") were $55.3 million compared to $47.2 million for the year ended March 30,
1996 ("FY 1996"). The increase in net revenues of approximately 17.2% was
primarily due to increased sales made to one significant customer. Although net
revenues increased from FY 1996 to FY 1997, net revenues generated from sales of
products
 
                                       93
<PAGE>   109
 
overseas decreased from $11.9 million during FY 1996 to $7.7 million during FY
1997. The decrease in net revenues generated from overseas sales was due, in
part, to Artecon's decision to shift its overseas market focus from a strategy
of selling to a significant number of countries worldwide, to focusing on a
limited number of key target markets, specifically Europe (primarily the United
Kingdom, France and the Netherlands) and Japan, regions where Artecon's
management believes there is greater potential for growth in market share.
Management expects to continue this focus in the future, emphasizing higher
margin, more sophisticated products sold increasingly through Company owned or
controlled overseas operating units.
 
     Gross Margin. Gross margin for FY 1997 was $12.5 million, or 22.6% of net
revenues compared to a gross margin of $12.5 million, or 26.5% of net revenues
for FY 1996. The decrease in gross margin from FY 1996 to FY 1997 was primarily
attributable to a combination of foreign currency translations on Artecon's
sales of products overseas and the decrease in overseas sales of products, which
typically have a higher profit margin than domestic sales of products.
 
     Selling, General and Administrative Expenses. Selling, general and
administrative expenses increased to $9.0 million, or 16.3% of net revenues, for
FY 1997 from $8.9 million, or 18.9% of net revenues, for FY 1996. The increase
in selling, general and administrative expenses of approximately $100,000 for FY
1997 compared to FY 1996 was due to increased sales of Artecon's products,
primarily attributable to an increase in the number of Artecon's sales
personnel.
 
     Research and Development Expenses. Research and development expenses
increased to $2.3 million, or 4.2% of net revenues for FY 1997, compared to $1.4
million, or 3% of net revenues for FY 1996. The increase of approximately
$900,000, or 64.3%, in research and development expenses was due to Artecon's
continued development of new products.
 
     Total Other Expense. Total other expense decreased from $898,000 for FY
1996 to $247,000 for FY 1997. The decrease in total other expense of
approximately 72.5% was due in large part to a loss during FY 1996 of $336,000
related to foreign currency transactions. In addition, during FY 1996, Artecon
terminated a significant portion of the operations of its French-based
subsidiary, resulting in an unusual charge of $256,000. Artecon is exposed to
foreign currency exchange risk in each of its key overseas markets. Exposure
relates primarily to exchange rate fluctuations between the U.S. Dollar and the
Japanese Yen, British Pound, French Franc and Dutch Guilder. Overseas
operations' sales are made and operating expenses incurred in the local
currency. Product purchases are made in U.S. Dollars. The Company has
historically not actively managed its foreign currency exchange risk, except as
it relates to Japan. The Japanese operation has obtained local currency
financing and, from time to time, takes out forward contracts related to
anticipated purchases of U.S. product.
 
     YEAR ENDED MARCH 30, 1996 COMPARED TO YEAR ENDED MARCH 25, 1995
 
     Net Revenues. Net revenues remained essentially the same for FY 1996 and
for the year ended March 25, 1995 ("FY 1995"), totaling $47.2 million for FY
1996 and $47.8 million for FY 1995. During FY 1996, Artecon chose not to
continue sales of HP workstations. The decrease in net revenues resulting from
Artecon's decision to discontinue selling HP workstations was partially offset
by an increase in sales of its Lynx and Sphinx product lines.
 
     Gross Margin. Gross margin for FY 1996 was $12.5 million, or 26.5% of net
revenues, compared to a gross margin of $9.5 million, or 19.9% of net revenues,
for FY 1995. The increase in gross margin from FY 1995 to FY 1996 was primarily
attributable to increased sales of Artecon's Lynx family of products, which
typically generate higher margins than sales of third party products.
 
     Selling, General and Administrative Expenses. Selling, general and
administrative expenses for FY 1996 were $8.9 million, or 18.9% of net revenues
compared to $7.9 million, or 16.5% of net revenues for FY 1995. The increase in
selling, general and administrative expenses in FY 1996 was due in part to
increased sales, the opening of two new European sales offices and an increase
in Artecon's sales force.
 
     Research and Development Expenses. Research and development expenses for FY
1996 were $1.4 million, or 3% of net revenues compared to $1.1 million, or 2.3%
of net revenues, for FY 1995. The increase in
 
                                       94
<PAGE>   110
 
research and development expenses of approximately $300,000 from FY 1995 to FY
1996 was attributable primarily to Artecon's continued development of new
products.
 
     Total Other Expense. Total other expense increased to $898,000 for FY 1996
from $64,000 for FY 1995. The increase was due primarily to a combination of a
one-time charge of $256,000 associated with the termination of a significant
portion of the operations of Artecon's French-based subsidiary and to losses on
foreign currency transactions.
 
INCOME TAXES
 
     Artecon accounts for income taxes in accordance with Statement of Financial
Accounting Standard (SFAS) No. 109, Accounting for Income Taxes, which requires
recognition of deferred tax assets and liabilities for the expected future tax
consequences of events that have been included in the financial statements or
tax returns of Artecon. Under SFAS 109, deferred tax assets and liabilities are
determined based on the difference between the financial statement and tax bases
of assets and liabilities using the enacted tax rates in effect for the year in
which the differences are expected to reverse.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     Since inception, Artecon has financed its operations primarily through a
combination of cash generated from operations and bank borrowings and through
sales of its capital stock. Artecon had approximately $12.5 million of accounts
receivable as of December 31, 1997.
 
     Artecon has a credit facility with a United States bank which permits
borrowings of up to $12,500,000 based upon a percentage of accounts receivable
and inventory. Artecon may choose between borrowing at the bank's prime rate, as
it may vary from time to time, or it may choose a rate that is fixed for an
agreed-upon period of from 30 to 180 days with interest due quarterly at the
LIBOR rate in effect at the commencement of the agreed-upon fixed period, plus
2.0%. The line of credit requires that Artecon comply with certain covenants,
including minimum tangible net worth requirements. Certain minimum amounts apply
to advances under the line of credit and such amounts must be borrowed for a
minimum of 30 days. The line of credit is secured by all of the assets of
Artecon. The revolving credit facility expires on September 1, 1999. Interest is
payable monthly. Principal is payable at the end of the term. The total
outstanding balance under the line of credit as of December 31, 1997 was $9.7
million. Artecon was not in compliance with the cash flow coverage ratio and
financial performance covenants associated with its line of credit for the
quarter ended December 31, 1997. The noncompliance for the quarter was primarily
the result of severance costs at Falcon. Artecon obtained a waiver from the bank
as of and for the quarter ended December 31, 1997. Artecon does not anticipate
that future liquidity will be impacted by the bank's covenant requirements,
since management anticipates that all covenants will be met, and that the bank
financing agreements will be amended or replaced after consummation of the
Merger.
 
     Artecon's Japanese subsidiary has three lines of credit with a Japanese
bank for borrowings of up to an aggregate of 75 million Yen (approximately
US$580,000 at December 31, 1997) at interest rates ranging from 1.62% to 2.4%.
Interest is due monthly with principal due and payable on various dates through
February 27, 1999. Borrowings are secured by the inventories of the Japanese
subsidiary. As of December 31, 1997, the total amount outstanding under the
three credit lines was 60 million Yen (approximately US$460,000).
 
     Artecon also has a long-term equipment loan secured by certain computers
used in its operations. As of December 31, 1997, the total amount outstanding on
the equipment loan was $219,000.
 
     On August 21, 1997, Artecon acquired substantially all of the assets and
liabilities of Falcon (the "Falcon Acquisition"), other than certain technology
assets (the "Falcon Technology"), in exchange for $1,000,000 in cash and a
promissory note in the original principal amount of $1,250,000 (the "Artecon
Note"). Subsequent to the issuance of the Artecon Note, Artecon and Falcon
amended the Artecon Note to decrease the principal amount due thereunder to
$750,000. Concurrently with the Falcon Acquisition, Falcon transferred the
Falcon Technology to Founding Partners, a California general partnership
("Founding Partners"), in exchange for a promissory note in the principal amount
of $1,750,000 (the "Founding Partners Note"). Dana Kammersgard, James Lambert
and W.R. Sauey, each of whom is an executive officer and/or director of Artecon,
are the general partners of Founding Partners. Founding Partners is considered
to be a Special Purpose Entity and,
 
                                       95
<PAGE>   111
 
accordingly, has been consolidated with Artecon for financial reporting
purposes. The purchase price was allocated among the acquired assets to
$10,232,000 for other assets acquired, $638,000 to goodwill and other intangible
assets, $14,138,000 for liabilities assumed and to in-process research and
development expenses of $3,700,000, which had no future alternative use, based
on management assumptions. Under the terms of the Artecon Note, as adjusted, and
the Founding Partners Note (collectively, the "Notes"), Artecon and Founding
Partners, respectively, are required to make monthly payments to Falcon of
$15,935 and $37,182, respectively, through August 2002. Each of the Notes bears
interest at the rate of 10% per annum. As of December 31, 1997, the total amount
of principal and interest outstanding under the Artecon Note was $710,722, and
the total amount of principal and interest outstanding under the Founding
Partners Note was $1,658,468.
 
     In connection with the Falcon Acquisition and the transfer of the Falcon
Technology, Artecon and Founding Partners entered into a Technology License
Agreement, dated August 21, 1997, pursuant to which Founding Partners granted to
Artecon an exclusive, perpetual license of the Falcon Technology in exchange for
monthly payments of $39,000 payable through August 2002.
 
     As of December 31, 1997, Artecon's future commitments under its operating
leases totaled approximately $2.2 million.
 
     Capital spending for FY 1997 and for the nine months ended December 31,
1997 were $260,000 and $440,000, respectively. Artecon anticipates capital
expenditures of $600,000 for the year ending March 31, 1998. This is a
forward-looking statement reflecting current beliefs and expectations. Actual
capital expenditures may vary from those anticipated and will be affected by a
number of factors, including those set forth below.
 
     Artecon's sales and operating results have in the past fluctuated from
quarter to quarter and may vary in the future depending on a number of factors,
including: the size and timing of significant purchase orders; the timing of
hardware shipments by third-party vendors necessary to recognize revenues; the
ability of Artecon to continue to design, develop and market new products and
services; market acceptance of new products; Artecon's success in increasing its
domestic and foreign sales force; the size and number of new accounts;
technological changes in the storage systems market; the growth of the
telecommunications and Internet/ intranet industry; reduction in demand for
Artecon's products as a result of new product introductions by competitors;
levels of expenditure on research and development; the amount of additional
capital needed by Artecon and the timing of such need; product quality problems;
fluctuations in foreign currency exchange rates; and general economic trends and
other factors. Sales and operating results for past periods are not necessarily
indicative of future periods and a period-to-period comparison of its sales or
results of operations are not necessarily meaningful and should not be relied
upon as an indicator of future performance.
 
     Artecon's management believes that its cash, resources from operations and
amounts available under its line of credit are sufficient to meet its current
capital commitments and operating requirements of its existing business for a
period of at least twelve months. However, there can be no assurance that
Artecon will not need to obtain additional capital before such time. The actual
amount and timing of working capital and capital equipment expenditures that
Artecon may incur in future periods may vary significantly and will depend upon
numerous factors, including the amount and timing of the receipt of resources
from continued operations, the increase in manufacturing capabilities, the
timing and extent of the introduction of new products and services, and growth
in personnel and operations.
 
     YEAR 2000 COMPLIANCE. Many currently installed computer systems and
software products are coded to accept only two digit entries in the date code
field. Beginning in the year 2000, these date code fields will need to accept
four digit entries to distinguish 21st century dates from 20th century dates. As
a result, in less than two years, computer systems and/or software used by many
companies may need to be upgraded to comply with such "Year 2000" requirements.
Significant uncertainty exists in the software industry concerning the potential
effects associated with such compliance. There can be no assurance that the
impact of the Year 2000 issue will not have a material adverse effect on
Artecon's internal operations or on sales of its software products.

                        CHANGE IN ACCOUNTANTS OF ARTECON
 
     In March 1997, Ernst & Young LLP ("Ernst & Young") resigned as independent
auditors of Artecon.
 
     None of Ernst & Young's reports on Artecon's financial statements for the
fiscal years ended March 30, 1996 and March 25, 1995 contained an adverse
opinion or disclaimer of opinion, nor were their opinions qualified or modified
as to audit scope or accounting principles. During the fiscal years ended March
30, 1996 and March 25, 1995 and the subsequent interim period through Ernst &
Young's resignation, there were no disagreements with Ernst & Young on any
matter of accounting principles or practices, financial statement disclosure or
auditing scope or procedure, which, if not resolved to Ernst & Young's
satisfaction, would have caused them to make reference to the subject matter of
the disagreement in connection with their reports, nor were there any reportable
events of the type requiring disclosure under Item 304(a)(1)(v) of Regulation
S-K.
 
     At a meeting held on March 7, 1997, the Board of Directors of Artecon
approved the selection of Deloitte & Touche LLP as Artecon's independent
auditors for the fiscal year ended March 29, 1997. During the fiscal year ended
March 29, 1997, Artecon has not consulted with Deloitte & Touche LLP regarding
the application of accounting principles or type of audit opinion that might be
rendered nor any matter that was either the subject of a disagreement, as that
term is defined in Item 304(a)(1)(iv) of Regulation S-K and the related
instructions to Item 304 of Regulation S-K, or a reportable event of the type
requiring disclosure under Item 304(a)(1)(v) of Regulation S-K.

                                ARTECON BUSINESS
 
     The following discussion contains forward-looking statements that involve
risks and uncertainties. Artecon's and the combined entity's actual results
could differ materially from those discussed here. Factors that could cause or
contribute to such differences include, but are not limited to, those discussed
in the sections entitled "Risk Factors" and "Artecon Management's Discussion and
Analysis of Financial Condition and Results of Operations," as well as those
discussed elsewhere in this Prospectus/Joint Proxy Statement.
 
     Artecon designs, manufactures, markets and supports a broad range of
scalable, fully integrated data storage products for the open-systems computing
environment. Artecon has established itself as a leader in the design,
manufacture and sale of third-party mass storage and enhancement products in the
Sun Microsystems ("Sun") and UNIX markets, offering both host-attached and
network-attached storage solutions for a broad range of customers. Artecon's
enterprise storage product line includes scalable RAID systems which allow users
to grow modularly from a single mass storage device to over ten terabytes
("10TB") of rack-mounted, fault-tolerant mass storage, thereby meeting the
capacity and performance needs of a wide range of customers while protecting and
maintaining customer investment. Artecon's telecommunications infrastructure
storage products represent what Artecon believes is the industry's only fully
NEBS-certified, multi-terabyte solution for high-end, application-specific needs
of telecommunications and government customers using commercial off-the-shelf
("COTS") workstation technology. Artecon also markets rack-mount solutions for
COTS workstations and servers and provides systems integration and a variety of
other service and support programs.
 
     In August 1997, Artecon acquired substantially all of the assets and
liabilities of Falcon, a network-attached storage server integrator and storage
peripherals reseller, in a transaction accounted for as a purchase. The Falcon
acquisition enabled Artecon to achieve several important strategic objectives,
including the acquisition of Artecon's AerREAL(TM) real-time specialized file
server software and other complementary products to better serve Artecon's
existing customers, the expansion of Artecon's customer base in the UNIX,
Windows NT and Windows 95 markets and a significant expansion of Artecon's
revenue base.
 
INDUSTRY BACKGROUND
 
     The rapid proliferation of new data-intensive applications, such as video,
the Internet, intranets, multimedia, data warehousing and data mining, and the
migration of mission-critical applications away from mainframe computers have
fueled the demand for open-systems data storage. Disk storage systems, tape
backup systems and software-based management tools designed to operate on
multiple platforms are becoming a strategic part of the MIS environment. MIS
purchase decisions are becoming increasingly focused on data storage and,
increasingly, capital expenditures for storage systems are equal to or greater
than those made on computer processing hardware. Storage architectures based on
protocols such as UltraSCSI and Fibre Channel Arbitrated Loop ("FC-AL") and
topologies such as Storage Area Network ("SAN") are driving a much greater focus
on data center purchasing towards storage. Currently, the industry is split into
solutions based on host-attached storage and solutions based on network-attached
storage.
 
     UNIX and Windows NT. Open-systems platforms today employ either UNIX
variants such as Solaris (Sun), HPUX (HP), AIX (IBM), IRIX (SGI) or Windows NT
from Microsoft. Together, these operating systems are installed on the vast
majority of computers used in the enterprise. UNIX platforms currently have the
largest installed user base in terms of numbers of units, with the Windows NT
user base expanding. International Data Corporation ("IDC"), an independent
market research firm, estimates that the worldwide market for RAID storage
systems in UNIX environments will grow at a compounded annual growth rate of
19.3%, increasing from $6.3 billion in 1996 to $12.9 billion in 2000. In
addition, IDC estimates that the worldwide market for RAID storage systems in
Windows NT environments will grow at a compounded annual growth rate of 34.1%,
increasing from $1.3 billion in 1996 to $4.3 billion in 2000.
 
     Many companies use a combination of both types of systems, often employing
Windows NT-based Intel machines for front office work (e.g., accounting, office
support, administration) and UNIX-based RISC workstations for back office
functions such as engineering and manufacturing. More recently, Windows NT
workstations have been developed by companies such as Compaq and HP, among
others, to challenge the dominance of UNIX workstations in the engineering,
scientific and other technical arenas. This has resulted in a gradual but steady
transition from the UNIX-installed base towards Windows NT, further exacerbating
the
 
                                       98
<PAGE>   114
 
need for open-systems storage solutions that support both operating systems on
platforms from a variety of vendors.
 
     Host-Attached Storage. The open-systems market's current host-attached
storage options include disk arrays, RAID storage systems and tape backup
systems. Each of these is generally attached to the host by the Small Computer
Systems Interface ("SCSI"). UltraSCSI has been the dominant commercially
available interface currently used in most disk array and RAID storage systems.
Fibre Channel, an emerging high-speed serial interface that has recently become
commercially available, is regarded by many industry participants as the storage
industry's next-generation interface. Fibre Channel enables the transfer of data
between computers and peripherals at substantially increased rates, over greatly
increased cabling lengths and among a greater number of host/device connections.
A number of industry leaders, including Microsoft Corporation, Seagate, Quantum,
IBM, Sun, Adaptec, Inc. and Emulex Corporation, have indicated support for Fibre
Channel technology and have announced that they are producing or plan to produce
products that incorporate it.
 
     Network-Attached Storage. The requirements of the data-intensive network
environment have contributed to the growing importance of the network file
service function, which involves reading and writing files to and from shared
data storage over the network. Until recently, the file service function had
been performed exclusively by larger, generalpurpose computer systems which also
executed other tasks such as print serving, application processing and
communications functions. As networks evolved, network managers increasingly
dedicated general-purpose systems specifically to the file service task in order
to enhance performance, simplify administration and reduce vulnerability to
other applicationrelated failures. These dedicated systems became known as "file
servers."
 
     Systems vendors have offered a variety of specially configured and add-on
solutions for general-purpose systems deployed as file servers. Selected vendors
have also introduced highly specialized, hardware-intensive systems designed to
exclusively perform the file service task. These approaches, such as the use of
hardware accelerators and the introduction of specialized hardware
architectures, have been optimized for throughput. However, they are generally
not designed to address the specific problem of response time, which is critical
in data-intensive network environments. In addition, because these approaches
lack the flexibility to easily integrate additional network, file system and/or
disk interfaces or protocols associated with today's heterogeneous networks
(such as mixed UNIX and NT networks), these approaches do not directly address
the reliability and access issues associated with data storage on a network.
Consequently, network-attached storage systems have lacked cost-effective,
flexible solutions to address data-access performance, data administration and
data availability and reliability issues in the data-intensive network
environment.
 
     The Internet and the World Wide Web (WWW). The virtual explosion of the
Internet and subsequently corporatewide intranets has had a profound impact on
the computer industry in general and on the demand for storage solutions in
particular. The Internet and intranet environments involve intensive processing
or computation of, and frequent user access to, large volumes of data and
consequently require a mission critical level of high-availability mass storage.
Moreover, the data intensity of these environments is expected to continue to
increase substantially due to the development of new applications and services
and the more prevalent use of stored digital graphics, voice and video,
requiring dramatically more data capacity and performance than equivalent
alphanumeric information.
 
     Telecommunications Industry. The enactment by Congress of the
Telecommunications Deregulation Act in 1996, the opening up of additional radio
frequency spectrum for wireless communications by the Federal Communications
Commission ("FCC") and other significant recent developments have spurred
dramatic changes in the worldwide telecommunications industry. The development
and build-out of expanded markets and new modes of communication that have been
enabled by these changes, including digital cellular systems, personal
communications systems ("PCS"), satellite-based communications systems, Internet
and cable systems, will require enormous capital expenditures for new
infrastructure. Artecon believes that a significant element of the required
infrastructure will consist of high performance mass storage systems that must
be specially adapted and certified for use in the telecommunications industry.
Telecommunications companies are seeking COTS-based solutions that can be
adapted and deployed in their embedded architectures due to ever-increasing cost
pressures and time-to-market constraints. These solutions are typically based on
UNIX and/or Windows NT systems and employ highly redundant RAID storage systems.

THE ARTECON SOLUTION
 
     Artecon develops and markets a comprehensive range of scalable, fully
integrated data storage products and services for the open-systems computing
environment. Artecon's products are both host attached and network attached,
based on a common architecture allowing scalability from the first desktop mass
storage unit purchased to multi-terabyte data center installations. Artecon's
family of products and services is intended to provide users with the following
benefits:
 
     - High Performance with Mission-Critical High Availability. Recognizing the
       increased demand for faster response times, greater capacities, higher
       availability of data and minimum system downtime, Artecon has focused on
       developing high-end, high-performance storage products using SCSI, Ultra
       SCSI and Fibre Channel interfaces. Redundant system components such as
       dual power inlets and multiple fans are intended to virtually eliminate
       any single point of failure to ensure maximum system uptime.
 
     - Scalability. Artecon's products are designed using a flexible, modular
       architecture allowing Artecon to size and configure storage systems to
       the application-specific requirements of individual customers. In
       addition, this architecture allows Artecon to resize and reconfigure
       these systems to adapt to the changing needs of customers, while allowing
       them to retain capital value in their underlying systems. By allowing
       users to grow modularly from a single mass storage device to over 10
       terabytes of rack-mounted, fault-tolerant RAID mass storage, Artecon's
       Lynx hot-plug removable mass storage subsystems address the capacity and
       performance needs of customers while protecting customer investment.
 
     - Multi-Platform Support. As an independent provider of storage products,
       Artecon is well positioned to provide storage systems specifically
       designed to be compatible with a variety of UNIX and Windows NT
       platforms. This cross-platform capability allows end users to standardize
       on a single storage system that can readily be reconfigured and
       redeployed at minimal cost as operating systems or other open-system
       components change.
 
     - High-Performance Backup. To satisfy market demand for reliable,
       high-quality backup products and systems, Artecon offers a broad variety
       of backup products, including tape library systems, backup software,
       training and documentation. Artecon has specialized expertise in the
       design and implementation of effective, well-integrated backup solutions
       designed to satisfy customers' individual needs, from departmental server
       systems to enterprise network systems.
 
     - All-Encompassing Solutions. Artecon delivers all-encompassing solutions
       including design consulting, systems integration, installation, training,
       comprehensive service and technical support and software-based management
       tools. Artecon employs a full staff of direct sales personnel and
       applications engineers to assist customers in making appropriate and
       effective storage system purchases and in addressing, analyzing and
       solving complex, pre-deployment storage problems. This value-added
       capability fosters customer loyalty and allows Artecon to identify
       emerging customer requirements for future data storage products.
 
ARTECON'S STRATEGY
 
     Artecon's objective is to continue its growth and enhance its position as a
leading independent provider of host-attached and network-attached storage
solutions to the open-systems marketplace. To achieve this objective, Artecon
plans to build upon its record of successfully introducing and commercializing
new products and technologies that address the evolving data storage needs of
its broad customer base. Key elements of this strategy are:
 
     - Complement Major Platform Vendors. Artecon intends to continue to pursue
       its strategy of complementing the major platform vendors, including Sun,
       Hewlett Packard ("HP"), Silicon Graphics ("SGI"), IBM and others, by
       engineering, manufacturing and marketing value-added products that
       address a broad spectrum of customer needs while enhancing and extending
       the platform vendor's own product lines. For example, through Artecon's
       Telecommunications Products Division, Artecon has extended Sun and other
       COTS workstation products into the -48VDC telecommunications market.
 
                                       100
<PAGE>   116
 
     - Provide Complete Solutions and Product Migration Path. Artecon's products
       are designed to address a wide range of customer needs. By utilizing
       common core technology throughout its product line, Artecon enables
       customers to migrate from product to product to address the changing
       needs of growing companies. By providing comprehensive solutions, Artecon
       is able to work more closely with customers, offer additional modules or
       products and provide additional services as an ongoing course of
       business.
 
     - Continued Emphasis on Sun Microsystems Market. Artecon intends to
       maintain its status as a leading third-party provider of mass storage and
       enhancement products for use in conjunction with Sun (or SGI) computer
       systems, both by continuing its focus on the primary Sun distribution
       network and by continuing its active participation as a strategic
       telecommunications partner of Sun. Artecon's Sun distribution channels
       include SunExpress, Merisel, Access Graphics, Ingram Micro, GTSI, Sun
       Federal and C. Itoh.
 
     - Expanded Market Penetration. Artecon intends to diversify its market
       penetration beyond products used in conjunction with Sun (or SGI)
       computer systems into other UNIX and the Windows NT markets. Artecon has
       recently begun to extend its resale channels into the SGI market. Artecon
       believes that Windows NT will, within the next few years, eclipse UNIX as
       the primary enterprise server operating environment. As a consequence,
       Artecon believes that Windows NT users will require the same large-scale,
       highavailability mass storage as current UNIX users require.
 
     - Focus on Specialized Storage Needs of Data-Intensive Markets. Artecon
       intends to continue to target users of UNIX and Windows NT computing
       environments who require high-performance, high-availability and
       fault-tolerant storage solutions, such as end users in data-intensive
       industries, particularly the telecommunications and Internet/intranet,
       financial services and multimedia markets. Artecon, as an independent
       provider of storage systems, believes that it is well positioned to
       address the multi-platform, multi-protocol computing requirements of
       these targeted high-end users.
 
     - Continue to Leverage Direct Sales Capabilities While Maintaining and
       Expanding Reseller Channels. Artecon believes that a properly managed,
       diverse distribution channel strategy should result in the greatest
       penetration of the market. Accordingly, Artecon utilizes both a direct
       sales force and extensive reseller distribution channels to penetrate
       major accounts while leveraging the reseller channel into vertical
       markets. Direct customer contact provides Artecon with invaluable market
       feedback and the ability to provide high-quality technical support and
       enhance customer loyalty. At the same time, however, Artecon recognizes
       that its success to date has been due in part to its strong relationships
       with its resale partners, both domestically and overseas, and believes
       that maintaining and expanding these distribution channels will provide
       Artecon with a significant competitive advantage.
 
PRODUCTS AND SERVICES
 
     Artecon's products and services are offered through two operating
divisions: the Enterprise Storage Division and the TeleCom Division. In order to
address the unique and highly specialized needs of the telecommunications and
Internet/intranet marketplace, Artecon formed its Telecom Division in June 1996.
Artecon's Enterprise Storage Division is responsible for the other markets
targeted by Artecon, including finance (for example, commodities brokers and
trading analysts), multimedia (such as entertainment providers, cable companies,
news services and the companies building infrastructure to serve them),
government, advanced-technology and industrial markets. Within these two
divisions of the company, Artecon's data storage solutions fall into four
general categories: enterprise storage, workstation and server rack solutions,
telecommunications infrastructure enabling technologies and systems integration
capability.
 
     ENTERPRISE STORAGE DIVISION
 
     Artecon provides enterprise storage solutions to its customers through its
Lynx product line. By allowing users to grow modularly from a single mass
storage device to over 10 terabytes of rack-mounted, fault-tolerant RAID mass
storage, Artecon's Lynx hot-swap removable mass storage subsystems address the
capacity and performance needs of customers while maintaining and protecting
customer investment. The Lynx unit is the fundamental building block of all
Artecon storage solutions and has several unique and differentiating features,
 
                                       101
<PAGE>   117
 
including interlocking stackability, cableless design, ruggedized hot-swap drive
sleds, front-removable power supplies and auto termination. To date, over 70,000
Lynx storage units have been installed.
 
     The Lynx line of storage solutions include LynxNSS network-attached storage
servers designed to meet the file storage and access needs of networked
environments and LynxArray and LynxStak RAID systems which offer host-attached
RAID protection and performance enhancement for creating highly available,
mission-critical storage systems. Artecon believes that the performance,
flexibility, true scalability, hot-swap removable components and compact form
factor provide significant benefits to its customers. Major customers for the
Lynx include GTE Government Systems, Salomon Brothers/Smith Barney, Swiss Bank,
PSINet, and the US Army, Marines and Navy.
 
     Artecon's LynxStak(TM) product is an interlocking modular desktop RAID
solution that easily scales from 4GB to 126GB as required. A single LynxStak
unit may be expanded with up to 14 drives, one at a time in the field by the end
user customer. A single LynxStak RAID controller may be joined with a second in
the field as requirements grow more demanding to ensure
no-single-point-of-failure operation. The LynxStak system uses the same
high-performing hot-swap drives and RAID controller as Artecon's LynxArray,
giving the customer a high degree of investment protection. The LynxStak RAID
system supports any 3.5" or half-height 5.25" devices. Hot-plug removable
options for controllers, drives, and power supplies are available. Major
customers for LynxStak include Geoquest/Schlumberger, Nike, Sharp Electronics,
and Philips.
 
     Artecon's LynxArray(TM) family of products provides a tower or rackmount
RAID solution. The LynxArray family (LR3000, LR-5000, LR-7000) uses the same
architecture as capacity scales from 27GB to over 10TB so that customer
investment is protected. LynxArray uses an Intel-based RAID controller that
operates at a speed of 4600 I/Os per second. UltraWide SCSI channels from host
computer through controllers to drives allow 40MB per second burst and 33MB per
second sustained transfer rates. LynxArray is also available with Fibre Channel
host interfaces that greater flexibility and enhanced performance. The LynxArray
supports up 162GB of hot-swappable disk capacity and two hot-swap failover RAID
controllers in only 7" (4u EIA) of vertical space to optimize precious rack
space. Inline support for tape drives makes backup possible within the RAID
subsystem. Hot swap removable options for failover controllers, any 3.5" or
half-height 5.25" devices, redundant power supplies and fans are all available
for more fail-safe, potentially nonstop operation. Major customers for LynxArray
include WorldCom/UUNet, Philips, ING Group, Digital Sound Corporation, U.S.
Navy, NTT (Japan), Lockheed Martin, Qualcomm, EDS and the British MOD.
 
     The LynxNSS(TM) is a family of specialized network-attached storage servers
dedicated to providing rapid file access for networks requiring 27 gigabytes
(27GB) to over 2 terabytes of storage. LynxNSS supports multiple file transfer
protocols to facilitate file sharing in heterogeneous computer environments
while network connectivity is furnished by a variety of network interfaces
including 10/100BASE-T Ethernet, FDDI, CDDI and quarter- and full-speed Fibre
Channel. Artecon believes that LynxNSS, which features multi-processor hardware,
specialized file server software, high-speed network technologies and
hardware-based RAID, offers better price/performance ratios than both
general-purpose servers and other specialized servers.
 
     LynxNSS also employs Artecon's AerREAL(TM) real-time specialized file
server software and multi-processor architecture to enhance performance, while
AerREAL's Journaling Automation System helps ensure data integrity and hotswap
components permit replacement without interrupting file service. The LynxNSS
allows mixed RAID levels so that different RAID levels can be chosen for each
application for best performance. Fully redundant failover configurations are
available for continuous mission-critical operation. Major customers of LynxNSS
include Lockheed Martin, California Department of Water, Oracle, and AT&T.
 
     WORKSTATION AND SERVER RACK SOLUTIONS
 
     Artecon's Sphinx(TM) workstation and server rack solutions enable users to
rackmount COTS desktop workstations from Sun and SGI into powerful,
application-specific servers. Sphinx products protect against shock and
vibration events, maintain the thermal integrity of the workstation/server,
enhance system physical security while providing a very compact expansion
capability. Artecon believes it offers a superior solution than the typical rack
shelf used for rackmounting workstations and servers. Sphinx also allows hot
swap removable devices to be added so that a variety of powerful and expandable
configurations can be constructed,
 
                                       102
<PAGE>   118
 
including high-end clustered compute servers, highavailability failover servers,
network servers and database servers.
 
     The Sphinx has a patented design intended to ensure that the workstation or
server remains unmodified so manufacturer's warranty, service, upgradability and
pricing are left intact. Other features include locking side rails with mounting
brackets, patented tuck-away, side-mounted lug handles, a locking front panel
for extra security, and flexibility to add up to an additional four hot swap
removable disks or CD, MO, and tape devices with a high degree of space
efficiency. Single or dual SCSI I/O connections provide fast, redundant access
to all devices. Power on/off, serial and keyboard ports are located on the front
of the chassis, and users have unobstructed access to the backplane of the
workstation or server for easy service.
 
     Artecon's Sphinx customers range from manufacturing floor and computer
center applications, to government agencies with requirements for shipboard,
aircraft and ground vehicle deployment of desktop workstations. Major customers
for Artecon's Sphinx include Sun Microsystems, Oracle, Adobe, the U.S. Air
Force, Navy and Army, Westinghouse and JPL.
 
     TELECOM DIVISION
 
     Artecon's TeleCom Division designs, manufactures, markets and supports
fully integrated, industry-compliant storage products, services and solutions
for the telecommunications ("telco") and Internet/intranet markets by utilizing
commercially available workstation, server and other application-specific
products for enhanced price/performance characteristics and reduced time to
market. Most of the products and services manufactured and marketed by Artecon's
Enterprise Storage Division can be utilized by telecommunications and Internet
service providers.
 
     Requirements unique to the telecommunications industry include -48VDC power
(native to the Central Office environment) and compliance with Bellcore's
Network Equipment-Building System ("NEBS") areas of standardization, which
include electromagnetic compatibility, thermal robustness, fire resistance,
earthquake and office vibration resistance, transportation and handling,
acoustics and illumination and airborne contaminants. Telco embedded
infrastructure projects are exceptionally demanding in terms of high
availability and redundancy due to the uptime requirements of the world's
telephone and communications support equipment. NEBS testing requires a
certified unit to be able to withstand an earthquake, a lightning strike, a
fire, severe airborne particulate contamination, extreme temperature ranges and
other catastrophic events. To date, Artecon is the only open-systems storage
company whose RAID products are fully certified to Bellcore NEBS standards. In
addition, Artecon's commercial enterprise storage products are built to the same
demanding standards, yielding very reliable systems for the commercial market.
 
     Telco Storage Solutions. Most of Artecon's enterprise storage products,
including LynxArray and LynxNSS, can be utilized by telecommunications and
Internet service providers. Artecon believes that it is currently the only RAID
vendor whose products have passed full NEBS certification, and Artecon's
LynxArray EXTREME products are already in use by telecommunications and ISP
providers such as Motorola, Qualcomm, AT&T, Lucent Technologies, MCI, Sprint,
Southwestern Bell, WorldCom/UUNet, Digital Sound Corporation, Intervoice, and
Intellivoice.
 
     Workstation and Server Rack Solutions. Artecon's Sphinx EXTREME product
line is fully NEBS-certified and has been instrumental in bringing Sun and SGI
workstation products into the telecommunications and typical Internet service
provider deployed (rack-mount) environment. Artecon's TeleCom Division Sphinx
customers include a wide range of telecommunications infrastructure and
Internet/intranet service providers building new Internet, wireless and PCS
services based on COTS workstations, including AT&T, Sprint, MCI, Qualcomm,
Motorola, Bell Atlantic/Nynex, and WorldCom/UUNet.
 
     Power Products. Artecon believes that its PowerSphinx(TM) EXTREME is the
industry's first 1.75" DC/DC power converter which allows unmodified COTS
workstations and other products to run in the
- -48VDC environment of the telecommunications Central Office. PowerSphinx EXTREME
enables workstation and networking products typically used in 110-240VAC
environments to run unmodified in the -48VDC context. Artecon believes this
feature may significantly accelerate its customers' time to market for new
infrastructure while reducing costs due to the ability to employ standard (as
opposed to custom) workstation, networking and other products.
 
                                       103
<PAGE>   119
 
     PowerSphinx EXTREME is designed for use with 110-240VAC devices such as
workstations, switches, routers and hubs so that they may operate in the -48VDC
telecommunications environment, thereby expanding the limits of available
product choices to engineers and integrators building telecommunications
systems. Artecon believes that the compact 1.75" EIA rack height is an improved
and preferable alternative to typically large (often as much as 21" or 12u EIA)
power inverters. PowerSphinx EXTREME has two hot-swappable, load-sharing power
modules to assure uninterrupted operation, combined with dual -48VDC inlet power
connections to help virtually eliminate any single point of failure. Other
features include 1600 watts of total power output, hot-plug removable power
trays and fans, alarm system and dual LED displays. The PowerSphinx EXTREME is
fully certified to Bellcore NEBS standards and is in use by such telco customers
as Qualcomm, MCI, Korea Telecom, Dutch PTT, Motorola, GTE, and Sprint.
 
     Telecommunications Services. Most of the regional Bell operating companies
("RBOCs"), InterExchange servers ("IXSs"), long-distance haulers ("LDHs") and
switch manufacturers lack the resources, time, expertise and inclination to
invest in internal integration of open systems and therefore look to a supplier
who can not only provide product but also single-source solutions. As a
consequence, Artecon believes that its systems integration services are
well-suited to the telecommunications market. Artecon has established product
and integration contracts with Motorola, Qualcomm and MCI.
 
     Artecon's systems integration services produce expandable systems with
maximum capabilities and space efficiency to suit each client's unique
situation. Artecon utilizes commercially available workstation, server,
networking and other application-specific products along with its own EXTREME
product line to produce highly customized solutions. By leveraging its unique
products, Artecon believes it can often create the most cost-efficient and in
many cases, the only viable solution for a telco or Internet customer's unique
requirements. Artecon's open-systems, COTS approach can accelerate customers'
time to market and provide customers with superior price/performance. Unlike
most systems integrators, Artecon does not require customers to purchase
computer systems from Artecon, and because the workstations or servers stay
unmodified, all manufacturer warranties and support agreements remain in effect.
With Artecon's extensive experience as systems integrator, innovative
engineering, excellence in manufacturing and comprehensive support, Artecon
believes it can provide its customers with powerful storage solutions.
 
     PRODUCTS IN DEVELOPMENT
 
     Artecon has several products in development including next-generation RAID
systems designed to increase the performance and density of current product
offerings. These systems are being designed to provide both UltraSCSI and FC-AL
interfaces as well as direct network attachment, and support capacities in
excess of 1.5 terabyte on a single controller set. In addition, Artecon is
developing significant enhancements to its AerREAL file server software,
including enhanced high-availability support, symmetric multiprocessing support,
higher-speed backup, and remote replication services. Artecon is also
engineering Sphinx products to support the latest offerings from workstation
vendors such as Sun Microsystems.
 
CUSTOMERS
 
     Artecon targets both the horizontal markets defined by the primary
workstation vendors, such as Sun, SGI, HP and IBM, and, increasingly, the
vertical markets of the data-intensive telecommunications, finance and
multimedia industries. Artecon's customers include OEMs, systems integrators,
value added resellers (VARs), distributors and end users and span market
segments ranging from computer manufacturers to government agencies. The
following customers of Artecon accounted for approximately that percentage of
Artecon's total revenues set forth below during the periods indicated: UUNET
Technologies (13.5%) and GTE Government Systems (11.9%) for the nine-months

SALES AND MARKETING
 
     Artecon utilizes both a direct sales force and reseller distribution
channels in the U.S. in order to provide broad market penetration for its
products. As of January 9, 1998, Artecon's U.S. field sales organization
consisted of 40 sales professionals located in 11 geographical markets,
including San Diego, Silicon Valley and Sacramento, California; Denver,
Colorado; Chicago, Illinois; Boston, Massachusetts; New York and Rochester, New
York; St. Louis, Missouri; Columbia, Maryland; and Herndon, Virginia. Artecon's
international marketing strategy has similarly been to utilize both a direct
sales force and reseller distribution channels for sales outside of the United
States. The Company's sales to customers located outside the United States
represented approximately 12.5%, 14.0%, 25.2% and 18.6% of Artecon's net
revenues for the nine months ended December 31, 1997 and for the fiscal years
ended March 31, 1997, 1996 and 1995, respectively. Direct sales organizations of
Artecon's subsidiaries in Japan (Tokyo, Osaka, Nagoya), the Netherlands
(Encschede), France (Paris) and the United Kingdom (London) consisted of 7 sales
professionals.
 
     Artecon also employs a leveraged sales model that utilizes distribution
channels tailored to the needs of each user type. Artecon has developed pricing
structures and field sales commission plans that are designed to minimize sales
channel conflicts. Artecon believes that this two-pronged sales strategy
provides a meaningful competitive advantage over competitors who only provide
products directly to end-user customers.
 
CUSTOMER SERVICE AND SUPPORT
 
     Artecon believes that its ability to provide comprehensive and responsive
support is an important element in penetrating new customer accounts and in
securing repeat business from existing customers. Artecon is committed to
providing superior customer service and support aimed at simplifying
installation, reducing field failures, minimizing system downtime and
streamlining administration.
 
     Service revenues have not comprised a significant portion of Artecon's
revenues. In certain geographical regions, and for an annual or quarterly fee,
Artecon maintains a staff of on-call technical personnel who are available to
visit the customer's site within a few hours. In other geographical regions,
Artecon indirectly
 
                                       105
<PAGE>   121
 
provides the same level of support by using third-party service companies. In
all cases, Artecon technical support engineers are available by phone on a seven
day, 24 hour basis.
 
     Artecon provides standard warranties with all products sold which are set
forth in various documents and agreements which are delivered to customers with
each product. As a general policy, Artecon ships replacement hardware components
to customers in advance of receiving returns of defective components under a
standard warranty, which generally runs three years. Artecon occasionally issues
credit in lieu of replacing a piece of equipment. A customer may also contract
for an extended warranty or on site maintenance support from Artecon on all
products.
 
RESEARCH AND DEVELOPMENT
 
     To date, Artecon has made substantial investments in research and
development, particularly in the areas of RAID, robotic backup, FC-AL, GUI
software development, and specialized file server software. Artecon's
engineering design team employs electrical engineering, mechanical engineering,
systems engineers and computer science professionals and places great importance
on the exchange of information with Artecon's sales and marketing and customer
support departments and with its distributors to develop new products and
product enhancements that anticipate and address technological changes and
evolving industry standards and customer needs.
 
     Artecon generally designs its products to have a modular architecture that
can be readily modified to respond to technological developments and paradigm
shifts in the open systems computing environment. This flexibility allows
Artecon to focus research and development resources on specific product
innovations and advancements. The modular architecture of the products meets
customer needs with solutions tailored to their applications and products that
can be adapted to changes in technology and in their computing environments.
 
     Artecon's engineering design teams work cross-functionally with marketing
managers, applications, technical and production engineers and customers to
develop products and product enhancements. Artecon employs a full staff of
applications engineers to assist customers in making appropriate and effective
storage system purchases and in addressing, analyzing and solving complex
pre-deployment storage problems. Artecon's technical support engineering team
and production engineering team also contribute to the quality,
manufacturability and usability of products from design to deployment. This
value-added capability fosters customer loyalty and allows Artecon to identify
emerging customer requirements for future data storage products.
 
     Artecon's expenses for research and development for fiscal years 1995, 1996
and 1997 were $1.1 million, $1.4 million and $2.3 million, respectively. As of
December 31, 1997, Artecon had 15 regular full-time and seven contract employees
engaged in research and development activities, of which four were specifically
focused on research and development of products and services directed at the
telecommunications and Internet/intranet markets.
 
     The data storage system market is characterized by rapid technological
change, changing customer needs, frequent new product introductions and evolving
industry standards. The introduction of products embodying new technologies and
increased storage capacities and the emergence of new industry standards could
render Artecon's existing products obsolete and unmarketable. Artecon's future
success will depend upon its ability to develop and introduce new products with
increasing storage capabilities on a timely basis that keep pace with
technological developments and emerging industry standards and address the
increasingly sophisticated needs of its customers. There can be no assurance
that Artecon will be successful in developing and marketing any new products
that respond to technological changes or evolving industry standards, that
Artecon will not experience difficulties that could delay or prevent the
successful development, introduction and marketing of new products, or that its
new products will adequately meet the requirements of the marketplace and
achieve market acceptance. In addition, storage system products like those
offered by Artecon may contain undetected errors or failures when first
introduced or as new versions are released. There can be no assurance that,
despite testing by Artecon and by current and potential customers, errors will
not be found in new products after commencement of commercial shipments,
resulting in a loss or delay in market acceptance, which could have a material
adverse effect on Artecon's business, operating results or financial condition.
 
                                       106

MANUFACTURING
 
     Artecon operates 43,000 square feet of manufacturing space consisting of 30
separate product lines at its Carlsbad, California facilities. Artecon's
products are manufactured according to ECO specification in an assembly-line
production process. State-of-the-art equipment and software include MRP,
Just-In-Time ordering, TQM and in-house FedEx tracking. Artecon strives to
develop close relationships with its suppliers, exchanging critical information
and implementing joint corrective action programs to maximize the quality of its
components, to reduce costs and inventory investments and to create flexibility
for rapid capacity expansion when required. Artecon believes that its current
facilities and capital equipment will be adequate to meet its manufacturing
needs in the foreseeable future.
 
     Artecon subcontracts some of its manufacturing, such as plastic molding,
metal bending, PCB fabrication and assembly, to qualified partners in the U.S.
and Asia. Artecon owns the design and tools/molds associated with the
manufacture of these parts. Artecon has designed and owns over 50 tools used to
produce various components of its Lynx, LynxStak, and LynxArray products. In
addition, Artecon relies upon a limited number of suppliers of several key
components utilized in the assembly of Artecon's products, including Seagate,
IBM, Quantum, Infortrend, Intel, CMD, Mylex and Sony. Artecon's reliance on its
manufacturing subcontractors and suppliers involves several risks, including: an
inadequate supply of required components; price increases; late deliveries; and
poor component quality. Although to date Artecon has been able to obtain its
requirements of components, there can be no assurance that Artecon will be able
to obtain its full requirements of such components in the future or that prices
of such components will not increase. In addition, there can be no assurance
that problems with respect to yield and quality of such components and
timeliness of deliveries will not occur. Disruption or termination of the supply
of these components could delay shipments of Artecon's products and could have a
material adverse effect on Artecon's business, operating results or financial
condition. Such delays could also damage relationships with current and
prospective customers. Artecon has experienced delays in the shipments of its
products in the past, principally due to an inability of vendors to deliver an
adequate supply of components, resulting in delay or loss of product sales.
Although these delays in the past have not had a material adverse effect upon
Artecon's business, operating results or financial condition, there can be no
assurance that in the future any such delays would not have such a material
adverse effect.
 
COMPETITION
 
     The market for Artecon's products is extremely competitive. Artecon has a
number of competitors in various markets, including HP, Sun, IBM, SGI, Compaq,
DEC, DG Clariion, MTI, and EMC Corporation, many of which have substantially
greater name recognition, engineering, manufacturing and marketing capabilities,
and greater financial and personnel resources than Artecon. In particular, a
number of Artecon's customers are also competitors, including Sun and SGI.
Artecon expects to experience increased competition from established and
emerging computer storage hardware and management software companies,
particularly HP, Sun, IBM, Compaq, DEC, and EMC Corporation.
 
     In addition, increased competitive pressure could lead to intensified
price-based competition, which could have a material adverse effect on Artecon's
results of operations. There also has been, and may continue to be, a
willingness on the part of certain large competitors to reduce prices in order
to preserve or gain market share. Artecon believes that pricing pressures are
likely to continue as competitors develop more competitive product offerings.
 
     The principal elements of competition in Artecon's markets include rapid
introduction of new technology, product quality and reliability, price and
performance characteristics, service and support and responsiveness to
customers. Artecon believes that, in general, it competes favorably with respect
to these factors. However, there can be no assurance that Artecon will be able
to compete successfully or that competition will not have a material adverse
effect on Artecon's business, results of operations or financial condition.

INTELLECTUAL PROPERTY
 
     Artecon's success depends significantly upon its proprietary technology.
Artecon relies on a combination of patent, copyright, trademark and trade secret
laws, employee and third-party nondisclosure agreements and technical measures
to protect its proprietary rights in its products.
 
     As of December 31, 1997, Artecon had been awarded a total of seven U.S.
patents covering certain elements of its products. There can be no assurance
that any additional patents will be issued, that Artecon will develop
proprietary products or technologies that are patentable, that any patent issued
in the future will provide Artecon with any competitive advantages or will not
be challenged by third parties, or that the patents of others will not have a
material adverse effect on Artecon's ability to do business. Artecon seeks to
protect its software, documentation and other written materials under trade
secret and copyright laws, which afford only limited protection. Artecon has
registered numerous trademarks and will continue to evaluate the registration of
additional trademarks as appropriate. Artecon generally enters into
confidentiality agreements with its employees and consultants and with key
vendors and suppliers. All released documentation of products, including
drawings, requirements specifications, source code, BOMs, costs and other
materials, are kept in a secure, centralized document control area.
 
     Artecon expects that companies in the storage system market will
increasingly be subject to infringement claims as the number of products and
competitors in Artecon's target markets grows. Although Artecon believes that
its products and trade designations do not infringe on the proprietary rights of
third parties, there can be no assurance that third parties will not assert
infringement claims against Artecon in the future. If such a claim is made,
Artecon will evaluate the claim as it relates to its products and, if
appropriate, may seek a license to use the protected technology. There can be no
assurance that Artecon would be able to obtain a license to use such technology
or that such a license could be obtained on terms that would not have a material
adverse effect on Artecon. If Artecon or its suppliers are unable to license
protected technology, Artecon could be prohibited from incorporating or
marketing products incorporating that technology. Artecon could also incur
substantial costs to redesign its products or to defend any legal action taken
against it. Should Artecon's products be found to infringe protected technology,
Artecon could be required to pay damages to the infringed party or be enjoined
from manufacturing and selling such products.
 
     Despite Artecon's efforts to protect its proprietary rights, unauthorized
parties may attempt to copy aspects of Artecon's products or to obtain and use
information that Artecon regards as proprietary. In addition, the laws of some
foreign countries do not protect proprietary rights to as great an extent as do
the laws of the United States. There can be no assurance that Artecon's means of
protecting its proprietary rights will be adequate or that Artecon's competitors
will not independently develop similar technology, duplicate Artecon's products
or design around patents issued to Artecon or other intellectual property rights
of Artecon.
 
EMPLOYEES
 
     As of January 9, 1998, Artecon had approximately 190 full-time employees
worldwide, including 95 in marketing, sales and service support, 56 in
manufacturing and quality assurance, 17 in engineering and research and
development and 22 in general administration and finance.
 
     None of Artecon's employees is represented by a labor union. Artecon has
experienced no work stoppages and considers its relations with its employees to
be good.
 
     Artecon's future performance depends in significant part upon the continued
service of its key technical and senior management personnel. Artecon provides
incentives such as salary and benefits to attract and retain qualified
employees. The loss of the services of one or more of Artecon's officers or
other key employees could have a material adverse effect on Artecon's business,
operating results or financial condition. Artecon's future success also depends
on its continuing ability to attract and retain highly qualified technical and
management personnel. Competition for such personnel is intense, and there can
be no assurance that Artecon can retain its key technical and management
employees or that it can attract, assimilate or retain other highly qualified
technical and management personnel in the future.

FACILITIES
 
     Artecon's principal administrative, sales, marketing, manufacturing and
research and development facility is located in approximately 70,000 square feet
of space in Carlsbad, California, including approximately 43,000 square feet of
manufacturing space. This facility is leased through 1999. Artecon leases other
sales offices through the U.S., as well as operations sites in Japan, France,
England and the Netherlands. Artecon believes that its existing facilities are
adequate for its current needs.
 
LEGAL PROCEEDINGS
 
     On February 3, 1998, Artecon filed a civil complaint in Santa Clara County
Superior Court including, without limitation, claims of breach of contract,
misappropriation of trade secrets and unfair competition against StorNet, Inc.
and certain individuals (Civil Case No. CV 771742). The Court issued a temporary
restraining order on February 3, 1998 against the defendants enjoining certain
actions. The Court further set for hearing on March 5, 1998 an Order to Show
Cause Why Preliminary Injunction should not issue against the defendants. On
March 5, 1998, a hearing was initiated. The Court provided the parties until
March 12, 1998 to file supplemental briefs and continued the remainder of the
hearing to March 16, 1998.

           CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS OF ARTECON
 
     On August 21, 1997, Artecon acquired substantially all of the assets and
liabilities of Falcon (the "Falcon Acquisition"), other than certain technology
assets (the "Falcon Technology"), in exchange for $1,000,000 in cash and a
promissory note in the original principal amount of $1,250,000 (the "Artecon
Note"). Subsequent to the issuance of the Artecon Note, Artecon and Falcon
amended the Artecon Note to decrease the principal amount due thereunder to
$750,000. Concurrently with the Falcon Acquisition, Falcon transferred the
Falcon Technology to Founding Partners, a California general partnership
("Founding Partners"), in exchange for a promissory note in the principal amount
of $1,750,000 (the "Founding Partners Note"). Dana Kammersgard, James Lambert
and W.R. Sauey, each of whom is an executive officer and/or director of Artecon,
are the general partners of Founding Partners. Founding Partners is considered
to be a Special Purpose Entity and, accordingly, has been consolidated with
Artecon for financial reporting purposes. The purchase price was allocated among
the acquired assets to $10,232,000 for other assets acquired, $638,000 to
goodwill and other intangible assets, $14,138,000 for liabilities assumed and to
in-process research and development expenses of $3,700,000, which had no future
alternative use, based on management assumptions. Under the terms of the Artecon
Note, as adjusted, and the Founding Partners Note (collectively, the "Notes"),
Artecon and Founding Partners, respectively, are required to make monthly
payments to Falcon of $15,935 and $37,182, respectively, through August 2002.
Each of the Notes bears interest at the rate of 10% per annum. As of December
31, 1997, the total amount of principal and interest outstanding under the
Artecon Note was $712,746, and the total amount of principal and interest
outstanding under the Founding Partners Note was $1,663,075.
 
     In connection with the Falcon Acquisition and the transfer of the Falcon
Technology, Artecon and Founding Partners entered into a Technology License
Agreement, dated August 21, 1997, pursuant to which Founding Partners granted to
Artecon an exclusive, perpetual license of the Falcon Technology in exchange for
monthly payments of $39,000 payable through August 2002.
 
     On December 27, 1997, Founding Partners and Artecon amended the Technology
License Agreement to provide for, among other things, the transfer of the Falcon
Technology from Founding Partners to Artecon upon the satisfaction in full of
Founding Partners obligations under the Founding Partners Note.
 
     Pursuant to certain commitments between Artecon and the Nordic Group, in
which W.R. Sauey holds a controlling interest, Artecon is obligated to pay fees
to the Nordic Group for certain software maintenance services provided by and
overhead costs incurred by the Nordic Group. Such fees total approximately
$9,000 to $11,000 per month and represent Artecon's portion of overhead costs
paid by the Nordic Group on its behalf. Such payments will terminate effective
upon the closing of the Merger. Artecon will evaluate whether to continue using
such services after the consummation of the Merger. In addition, Artecon leases
certain real property from W.R. Sauey at a monthly rental fee of approximately
$1,125 under a month-to-month lease between the parties, which lease will
continue in effect after the Merger.
 
     Since January 1997, Artecon has made a series of short-term loans to
Flambeau Corp., a company in which W.R. Sauey is the principal shareholder, in
the aggregate principal amount of $6,145,000. Such loans were made pursuant to
the terms of a promissory note dated January 16, 1997 which bore interest at a
rate of 7.25% per annum and which was due and payable on demand. The aggregate
principal amount (including $14,506 in total interest payments) was paid in full
by Flambeau Corp. in August 1997.
 
     Between 1994 and 1997, Artecon issued to Tesfaye Hailemichael, Artecon's
Chief Financial Officer and Vice President, Finance, an aggregate of 55,000
Performance Appreciation Plan Participation Units ("PPUs") under Artecon's
Participative Performance Appreciation Plan. On June 30, 1997, Mr. Hailemichael
and Artecon entered into an agreement whereby each PPU held by Mr. Hailemichael
was converted into one share of Artecon Common Stock.
 
     During the fiscal years ended March 31, 1995, 1996, 1997 and the nine
months ended December 31, 1997, Artecon made payments to certain entities
affiliated with W.R. Sauey (the "Nordic Group Companies") in the aggregate
amounts of $802,855, $162,105, $73,734 and $120,807, respectively, for the
purchase of certain products and services from the Nordic Group Companies. In
addition, during the fiscal years ended March 31, 1995, 1996, 1997 and the nine
months ended December 31, 1997, Artecon received payments for
 
                                       111
<PAGE>   127
 
the sale of certain products and services from certain of the Nordic Group
Companies in the aggregate amounts of $226,549, $97,674, $84,644 and $62,064,
respectively. As of December 31, 1997, Artecon had accounts receivable from
certain Nordic Group Companies in the aggregate amount of $46,773 and accounts
payable of zero.
 
     Since March 31, 1994, Artecon has made payments to W.R. Sauey and certain
of his affiliates in the aggregate amount of $585,700 in connection with the
repurchase of shares of Preferred and Preferred B of Artecon pursuant to an
Agreement for Repurchase of Preferred Shares of Stock at Artecon, Inc. dated
December 22, 1994 among Artecon, Flambeau Corp., Flambeau Products Corp., Seats,
Inc. and W.R. Sauey (the "Artecon Repurchase Agreement"). On December 23, 1997
the parties to the Artecon Repurchase Agreement amended such agreement to
provide for its termination upon consummation of the Merger.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
     No interlocking relationship exists between the Storage Dimensions Board or
Compensation Committee and the board of directors or compensation committee of
any other company, nor has any such interlocking relationship existed in the
past.
 
LIMITATION OF LIABILITY AND INDEMNIFICATION MATTERS
 
     Storage Dimensions' Certificate of Incorporation, as amended and restated,
limits the liability of directors to the maximum extent permitted by the
Delaware General Corporation Law (the "DGCL"). The DGCL provides that directors
of a corporation will not be personally liable for monetary damages for breach
of their fiduciary duties as directors except for liability arising out of (i) a
breach of their duty of loyalty to the corporation or its stockholders, (ii)
acts or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (iii) unlawful payments of dividends or unlawful stock
repurchases or redemptions as provided in Section 174 of the DGCL or (iv) any
transaction from which the director derived an improper personal benefit.
 
     Storage Dimensions' charter documents provide that Storage Dimensions shall
indemnify its officers, directors and agents to the fullest extent permitted by
law, including those circumstances where indemnification would otherwise be
discretionary. Storage Dimensions believes that indemnification under its
charter documents covers at least negligence or gross negligence on the part of
indemnified parties. Storage Dimensions has entered into indemnification
agreements with each of its directors and officers which may, in some cases, be
broader than the specific indemnification provisions contained in the DGCL. The
indemnification agreements may require Storage Dimensions, among other things,
to indemnify each director and officer against certain liabilities that may
arise by reason of their status or service as directors or officers (other than
liabilities arising from willful misconduct of a culpable nature) and to advance
such persons' expenses incurred as a result of any proceeding against him or her
as to which such person could be indemnified. Pursuant to the Reorganization
Agreement, Storage Dimensions has agreed that, from and after the consummation
of the Merger, Storage Dimensions will fulfill and honor in all material
respects the obligations of Storage Dimensions and Artecon pursuant to (i) each
indemnification agreement in effect at such time between Storage Dimensions and
each person who is or was a director or officer of Storage Dimensions and
Artecon at or prior to the Effective Time and (ii) any indemnification
provisions under Storage Dimensions' and Artecon's Certificate of Incorporation
or Articles of Incorporation, as the case may be, or Bylaws, as each is in
effect on the date of the Reorganization Agreement. The Certificate of
Incorporation or Articles of Incorporation, as the case may be, and the Bylaws
of Storage Dimensions and Artecon shall continue to contain the provisions with
respect to indemnification and exculpation from liability set forth in such
documents as of the date of the Reorganization Agreement and such provisions
shall not be amended, repealed or otherwise modified for a period of six years
after the Effective Time in any manner that would adversely affect the rights
thereunder of any Indemnified Party.
 
     At the present time, there is no pending litigation or proceeding involving
a director, officer, employee or other agent of Storage Dimensions in which
indemnification would be required or permitted. Storage Dimensions is not aware
of any threatened litigation or proceeding that could result in a claim for such
indemnification.

Common Stock has no preemptive or conversion rights or other subscription
rights. There are no redemption or sinking fund provisions applicable to the
Common Stock. All outstanding shares of Common Stock are fully paid and
non-assessable, and the shares of Common Stock to be outstanding upon
consummation of the Merger will be fully paid and non-assessable.
 
     Storage Dimensions Preferred Stock. Storage Dimensions has 10,000,000
shares of Storage Dimensions Preferred Stock authorized. The Storage Dimensions
Board has the authority to issue the shares of Storage Dimensions Preferred
Stock in one or more series and to fix the rights, preferences, privileges and
restrictions granted to or imposed on any unissued and undesignated shares of
Storage Dimensions Preferred Stock and to fix the number of shares constituting
a series and the designations of such series, without any further vote or action
by the stockholders. Storage Dimensions is soliciting Storage Dimensions
stockholder approval of the Certificate of Amendment that would, among other
things, authorize a Series A Preferred Stock consisting of 2,494,159 shares for
issuance in the Merger. Although it presently has no intention to authorize or
issue any other series of Preferred Stock, the Storage Dimensions Board, without
stockholder approval, can issue up to the remaining 7,505,841 shares of Storage
Dimensions Preferred Stock with voting and conversion rights which could
adversely affect the voting power or other rights of the holders of Storage
Dimensions Common Stock. The issuance of Storage Dimensions Preferred Stock may
have the effect of delaying, deferring or preventing a change in control of
Storage Dimensions. For a description of the rights, preferences and privileges
of the Storage Dimensions Series A Preferred Stock, see "OTHER
AGREEMENTS -- Amendment to Storage Dimensions Certificate of Incorporation."
 
     Registration Rights. Pursuant to an agreement between Storage Dimensions
and a number of holders (or their permitted transferees) ("Holders") of Storage
Dimensions Common Stock, the Holders are entitled to certain rights with respect
to the registration of the shares held by them under the Securities Act. If
Storage Dimensions proposes to register any of its securities under the
Securities Act, either for its own account or for the account of other security
holders, the Holders are entitled to notice of the registration and are entitled
to include, at Storage Dimensions' expense, such shares therein, provided, among
other conditions, that the underwriters have the right to limit the number of
such shares included in the registration. In addition, certain of the Holders
may require Storage Dimensions at its expense on not more than two occasions, to
file a registration statement under the Securities Act with respect to their
shares of Storage Dimensions Common Stock, and Storage Dimensions is required to
use its best efforts to effect the registration, subject to certain restrictions
and limitations. Further, certain of the Holders may require Storage Dimensions,
at its expense, to register their shares on Form S-3 when such form becomes
available to Storage Dimensions, subject to certain conditions and limitations.
 
     Effect of Certain Terms of Charter Documents and Delaware Anti-Takeover
Law. Certain provisions of Storage Dimensions' Certificate of Incorporation, as
amended, and Bylaws, as amended, the DGCL and Storage Dimensions'
indemnification agreements with certain officers and directors of Storage
Dimensions may be deemed to have an anti-takeover effect. Such provisions may
delay, defer or prevent a tender offer or
 
                                       122
<PAGE>   138
 
takeover attempt that a stockholder might consider to be in that stockholder's
best interests, including attempts that might result in a premium over the
market price for the shares held by such stockholder.
 
     The Storage Dimensions Board may issue additional shares of Storage
Dimensions Common Stock or designate and issue one or more classes or series of
Storage Dimensions Preferred Stock, having the number of shares (up to
10,000,000), designations, relative voting rights, dividend rates, liquidation
and other rights, preferences and limitations as determined by the Storage
Dimensions Board without stockholder approval. Storage Dimensions' Certificate
of Incorporation, as amended, and Bylaws, as amended, contain a number of
provisions that could impede a takeover or change in control of Storage
Dimensions, including but not limited to the elimination of stockholders'
ability to take action by written consent and a fair price requirement. In
addition, upon approval of the Certificate of Amendment by the Storage
Dimensions stockholders, the Storage Dimensions Certificate of Incorporation
will provide for a classified Board of Directors and provide that a director may
not be removed from office without cause except, until the third annual meeting
of Storage Dimensions following the Merger, by the affirmative vote of at least
80% of the outstanding voting stock of Storage Dimensions and by the affirmative
vote of at least 66 2/3 of the outstanding voting stock of Storage Dimensions
thereafter.
 
     In addition, Storage Dimensions is subject to the anti-takeover provisions
of Section 203 of the DGCL. In general, Section 203 prohibits a publicly-held
Delaware corporation from engaging in a "business combination" with an
"interested stockholder" for a period of three years after the date of the
transaction in which the person became an interested stockholder, unless the
business combination is approved in a prescribed manner. The term "business
combination" includes mergers, asset sales or other transactions resulting in a
financial benefit to the stockholder. An "interested stockholder" is a person
who, together with affiliates and associates, owns (or within three years, did
own) 15% or more of the corporation's voting stock. Section 203 could have the
effect of delaying, deferring or preventing a change in control of Storage
Dimensions. For a more detailed description of Section 203, see "COMPARISON OF
RIGHTS OF STORAGE DIMENSIONS STOCKHOLDERS AND ARTECON
SHAREHOLDERS -- Stockholder Approval of Certain Business Combinations."
 
     Each of the foregoing provisions gives the Storage Dimensions Board, acting
without stockholder approval, the ability to prevent, or render more difficult
or costly, the completion of a takeover transaction that stockholders might view
as being in their best interests.
 
     Storage Dimensions Transfer Agent and Registrar. The transfer agent and
registrar for the Storage Dimensions Common Stock is Boston Equiserve Limited
Partnership.
 
DESCRIPTION OF ARTECON CAPITAL STOCK
 
     The authorized capital stock of Artecon consists of 20,000,000 shares of
Common Stock, 10,000,000 shares of Preferred and 10,000,000 shares of Preferred
B (the Preferred and Preferred B are collectively referred to herein as the
"Artecon Preferred Stock"). As of the Artecon Record Date, there were 6,043,990
shares of Common Stock outstanding held of record by 55 shareholders, 1,111,951
shares of Preferred outstanding held of record by 13 shareholders and 1,405,208
shares of Preferred B outstanding held of record by two shareholders.
 
     Artecon Common Stock. Holders of Artecon Common Stock are entitled to one
vote per share on all matters to be voted upon by the shareholders. Shareholders
entitled to vote at any election of directors of Artecon may, subject to giving
notice at or prior to the meeting at which such vote will take place, cumulate
such shareholder's vote and give one candidate a number of votes equal to the
number of directors to be elected multiplied by the number of votes to which his
shares are entitled, or distribute his votes on the same principle among as many
candidates as such shareholder deems fit. Subject to preferences that may be
applicable to any outstanding shares of Artecon Preferred Stock, the holders of
Artecon Common Stock are entitled to receive ratably such dividends, if any, as
may be declared from time to time by the Artecon Board out of funds legally
available therefor. In the event of a liquidation, dissolution or winding up of
Artecon, the holders of Artecon Common Stock are entitled to share ratably in
all assets remaining after payment of liabilities, subject to prior liquidation
rights of shares of Artecon Preferred Stock, if any, then outstanding. The
Artecon Common Stock has no preemptive or conversion rights or other
subscription rights. There are no
 
                                       123
<PAGE>   139
 
redemption or sinking fund provisions applicable to the Artecon Common Stock.
All outstanding shares of Artecon Common Stock are fully paid and
non-assessable.
 
     Artecon Preferred Stock. Holders of Artecon Preferred Stock are not
entitled to vote on any matters to be voted upon by the shareholders, except for
matters to which holders of Artecon Preferred Stock are entitled to vote on
under the CGCL, including the Merger.
 
     Holders of Artecon Preferred Stock are not entitled to receive dividends.
Upon liquidation of Artecon, holders of shares of Preferred are entitled to a
$0.01 per share liquidation preference over all other classes of Artecon capital
stock, while holders of shares of Preferred B are entitled to a liquidation
preference of $2.00 per share over all other classes of Artecon capital stock,
except for shares of Preferred.
 
     Each share of Artecon Preferred Stock is convertible into 1.25 shares of
Common Stock at the option of the holders: (i) upon a public offering of any
shares of Artecon capital stock, (ii) upon the sale of any material portion of
Artecon's assets or shares of Common Stock, or (iii) at any time after three (3)
years from the date of issuance of such Artecon Preferred Stock (each a
"Conversion Event"). Each share of Preferred B may be redeemed by Artecon at any
time prior to receipt of a written election to convert by the holder subsequent
to a Conversion Event. Such redemption by Artecon must be accompanied by an
offer to pay the holder of Preferred B an amount equal to $2.00 per share plus
12 percent interest per year or partial year held to date of redemption.
 
     Pursuant to the Artecon Repurchase Agreement, certain holders of Artecon
Preferred Stock are subject to the optional repurchase by Artecon of certain of
their shares of Artecon Preferred Stock through the fiscal year ending March 31,
1999. The Artecon Repurchase Agreement will be terminated effective upon the
consummation of the Merger.

          COMPARISON OF RIGHTS OF STORAGE DIMENSIONS STOCKHOLDERS AND
                              ARTECON SHAREHOLDERS
 
     The rights of Storage Dimensions stockholders are governed by Storage
Dimensions' Certificate of Incorporation, as amended (the "Storage Dimensions
Certificate"), its Bylaws (the "Storage Dimensions Bylaws") and the DGCL. The
rights of Artecon shareholders are currently governed by Artecon's Articles of
Incorporation, as amended (the "Artecon Articles"), its Bylaws (the "Artecon
Bylaws") and the CGCL. In connection with the Merger, Storage Dimensions will
amend the Storage Dimensions Certificate pursuant to the Certificate of
Amendment. Upon consummation of the Merger, and given the requisite approval of
the Certificate of Amendment, Artecon shareholders will become stockholders of
Storage Dimensions with their rights as stockholders governed by the DGCL, the
Certificate of Amendment and the Storage Dimensions Bylaws.
 
     The following is a summary of certain similarities and differences between
the rights of Storage Dimensions stockholders and Artecon shareholders under the
foregoing governing documents and applicable law. This summary does not purport
to be a complete statement of such similarities and differences. The
identification of specific similarities and differences is not meant to indicate
that other equally or more significant similarities and differences do not
exist. Such similarities and differences can be examined in full by reference to
the DGCL, the CGCL and the respective corporate documents of Storage Dimensions
and Artecon.
 
     Capital Stock. The authorized capital stock of Storage Dimensions consists
of 40,000,000 shares of Storage Dimensions Common Stock, $0.005 par value, of
which 8,022,430 shares were issued and outstanding on the Storage Dimensions
Record Date, and 10,000,000 shares of Preferred Stock, issuable in such series
and with such rights, powers and privileges as the Storage Dimensions Board
shall determine. Storage Dimensions currently has no shares of Preferred Stock
outstanding. However, pursuant to the Certificate of Amendment, Storage
Dimensions will designate 2,494,159 shares of Series A Preferred Stock to be
issued to current holders of shares of Artecon Preferred and Preferred B in
exchange for such shares upon consummation of the Merger. The authorized capital
stock of Artecon consists of 20,000,000 shares of Common Stock, no par value, of
which 6,043,990 shares were issued and outstanding on the Artecon Record Date
and 10,000,000 shares of Preferred, no par value, of which 1,111,951 shares were
issued and outstanding on the Artecon Record Date, and 10,000,000 shares of
Preferred B, no par value, of which 1,405,208 shares were issued and outstanding
on the Artecon Record Date. See "DESCRIPTION OF ARTECON CAPITAL STOCK."
 
     Amendment of Bylaws. Under the DGCL, bylaws may be amended by stockholders
entitled to vote; however, a corporation may confer the power to amend bylaws
upon the directors. The fact that such power has been so conferred upon the
directors does not divest the stockholders of their power to amend the bylaws.
The Storage Dimensions Certificate states that the Storage Dimensions Bylaws may
be amended by the affirmative vote of at least a majority of the outstanding
stock entitled to vote thereon or by the Storage Dimensions Board. Under the
CGCL and the Artecon Bylaws, the Artecon Bylaws may be amended or repealed
either by the Artecon Board or by the holders of a majority in interest of the
outstanding shares of Artecon, except that a change in the authorized number of
directors may only be effected by a vote of the majority of the outstanding
stock entitled to vote thereon; however, under the CGCL, an amendment reducing
the minimum number of directors to less than five cannot be adopted if votes
cast against its adoption are equal to or more than 16 2/3% of the outstanding
shares entitled to vote thereon.
 
     Amendment of Storage Dimensions Certificate and Artecon Articles. The DGCL
provides that approval of a majority of the outstanding stock entitled to vote
thereon is required to amend a certificate of incorporation. The Storage
Dimensions Certificate provides that an amendment of certain provisions must be
approved by the affirmative vote of at least 66 2/3% of all of the outstanding
stock entitled to vote thereon. Under the CGCL, a corporation's articles of
incorporation may be amended by the approval of a majority of the outstanding
shares.
 
     Special Meetings of Stockholders and Shareholders. Under the DGCL, a
special meeting of stockholders may be called by the board of directors or by
any other person authorized to do so in the certificate of incorporation or the
bylaws. The Storage Dimensions Certificate permits a special meeting to be
called for any
 
                                       125
<PAGE>   141
 
purpose or purposes by (i) the Chairman or Vice-Chairman of the Storage
Dimensions Board, (ii) the President, (iii) the Storage Dimensions Board
pursuant to a resolution adopted by a majority of the total number of authorized
directors (whether or not there exist any vacancies in previously authorized
directorships at the time any such resolution is presented to the Storage
Dimensions Board for adoption) or (iv) by the holders of the shares entitled to
cast not less than 10% of the votes at the meeting.
 
     Under the CGCL and the Artecon Bylaws, a special meeting of shareholders
may be called by the board of directors, the chairman of the board of directors,
the president, a vice president, the secretary or by one or more of the holders
of shares entitled to cast not less than 10% of the votes of such meetings.
 
     Actions by Written Consent of Stockholders or Shareholders. Under the DGCL,
unless otherwise provided in the Storage Dimensions Certificate, any action
which may be taken at a meeting of stockholders may be taken without a meeting
and without prior notice if written consents setting forth the action so taken
are signed by the holders of outstanding stock having not less than the minimum
number of votes that would be necessary to authorize or take such action at a
meeting at which all stock entitled to vote thereon were present and voted.
However, the Storage Dimensions Certificate provides that no action shall be
taken by the stockholders by written consent.
 
     Under the CGCL, shareholders may execute an action by written consent in
lieu of a shareholder meeting. The Artecon Bylaws provide that any action which
may be taken at a meeting of shareholders may be taken without a meeting and
without prior notice if written consents setting forth the action so taken are
signed by the holders of outstanding shares having not less than the minimum
number of votes that would be necessary to authorize or take such action at a
meeting at which all shares entitled to vote thereon were present and voted. The
Artecon Bylaws provide further that directors may not be elected by written
consent except by unanimous written consent of all shares entitled to vote for
the election of directors; provided, however, that any vacancy on the Artecon
Board may be filled by written consent of a majority of the outstanding shares
entitled to vote for the election of directors.
 
     Size of the Board of Directors. The DGCL provides that the board of
directors of a Delaware corporation shall consist of one or more members. The
number of directors may be fixed by, or in the manner provided in, the
corporation's bylaws unless the certificate of incorporation fixes the number of
directors. The Storage Dimensions Certificate requires that the number of
directors shall be fixed by a resolution approved by the Board of Directors or
by the affirmative vote of holders of not less than 66 2/3% of all the
outstanding stock entitled to vote thereon. The number of directors of Storage
Dimensions is currently fixed at five.
 
     The CGCL allows the number of persons constituting the board of directors
to be fixed by the bylaws or the articles of incorporation, or permits the
bylaws to provide that the number of directors may vary within a specified
range, the exact number to be determined by the board of directors. The CGCL
further provides that, in the case of a variable board, the maximum number of
directors may not exceed two times the minimum number minus one. The Artecon
Bylaws currently provide that the number of directors authorized is five.
 
     Classification of Board of Directors. The DGCL permits, but does not
require, a classified board of directors, divided into as many as three classes
with staggered terms under which one-half or one-third of the directors are
elected for terms of two or three years, respectively. The CGCL generally
requires that directors be elected annually but does permit a "classified" board
of directors if the corporation is "listed." A listed corporation is defined
under the CGCL as one which (i) is listed on the NYSE or American Stock Exchange
or (ii) with a class of securities designated as a national market system
security on and by the National Association of Securities Dealers Automatic
Quotation System (or any successor national market system) if the corporation
has at least 800 holders of its equity securities. If eligible for the classes,
the CGCL permits corporations to provide for a board of directors divided into
as many as three classes by adopting an amendment to their articles of
incorporation or bylaws, which amendment must be approved by the shareholders.
The size of the classes must be as even as possible, and any change in number of
classes must be approved by the shareholders. Neither the Storage Dimensions
Bylaws nor the Artecon Bylaws provide for a classified board. However, the
Certificate of Amendment provides for a classified board of directors whereby
the directors will be separated into three classes with members of each class
serving for a three year term.
 
                                       126
<PAGE>   142
 
     Cumulative Voting. Under the DGCL, cumulative voting in the election of
directors is not available unless specifically provided for in the certificate
of incorporation. There is no provision for cumulative voting in the Storage
Dimensions Certificate or in the Certificate of Amendment. Under the CGCL,
cumulative voting in the election of directors is mandatory upon notice given by
a shareholder at a shareholders' meeting at which directors are to be elected.
To cumulate votes, a shareholder must give notice at the meeting, prior to the
voting, of the shareholder's intention to vote cumulatively. If any one
shareholder gives such a notice, all shareholders may cumulate their votes. The
CGCL permits a company, by amending its articles of incorporation or bylaws, to
eliminate cumulative voting when such company is "listed" (as defined above in
the section entitled "Classification of Board of Directors"). The Artecon Bylaws
permit any person entitled to vote at an election for directors to cumulate the
votes to which such person is entitled; provided, however, that no shareholder
shall be entitled to cumulate such shareholder's votes unless the candidates for
which such shareholder is voting have been placed in nomination prior to the
voting and a shareholder has given notice at the meeting, prior to the vote, of
an intention to cumulate votes.
 
     Removal of Directors. Under the DGCL, a director of a corporation with a
classified board of directors may be removed only for cause, unless the
certificate of incorporation otherwise provides. A director of a corporation
that does not have a classified board of directors or cumulative voting may be
removed with the approval of a majority of the outstanding shares entitled to
vote with or without cause. The Storage Dimensions Bylaws provide that any
director may be removed from office, with or without cause, at any special
meeting (the notice of which shall state that it is called for that purpose) by
the affirmative vote of the holders of the majority of the voting power of all
the outstanding stock entitled to vote thereon. However, the Amended Storage
Dimensions Certificate provides that a director may not be removed from office
without cause, except until the third annual meeting of Storage Dimensions
following the Merger by the affirmative vote of at least 80% of the outstanding
voting stock of Storage Dimensions and by the affirmative vote of at least
66 2/3% of the outstanding voting stock of Storage Dimensions thereafter.
 
     Under the CGCL, a director may be removed with or without cause by the
affirmative vote of a majority of the outstanding shares, provided that the
shares voted against removal would not be sufficient to elect the director by
cumulative voting. In addition, when, by the provisions of the articles of
incorporation, the holders of shares of a class or series, voting as a class or
series, are entitled to elect one or more directors, any director so elected may
be removed only by the applicable vote of holders of shares of that class or
series.
 
     Filling Vacancies in the Board of Directors. Under the DGCL, vacancies may
be filled by a majority of the directors then in office (even though less than a
quorum) unless otherwise provided in the certificate of incorporation or bylaws.
The DGCL further provides that if, at the time of filling any vacancy, the
directors then in office constitute less than a majority of the board (as
constituted immediately prior of any such increase), the Delaware Court of
Chancery may, upon application of any holder or holders of at least ten percent
of the total number of the outstanding stock having the right to vote for
directors, summarily order a special election be held to fill any such vacancy
or to replace directors chosen by the board to fill such vacancies. The Storage
Dimensions Bylaws provide that any vacancies on the Storage Dimensions Board
resulting from death, resignation, disqualification, removal or other causes and
any newly created directorships resulting from any increase in the number of
directors, shall be filled by the affirmative vote of the majority of the
directors then in office, even though less than a quorum of the Board of
Directors.
 
     Under the CGCL, 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 in office 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 properly noticed meeting 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 a corporation's shareholders. Furthermore, if, after the
filling of any vacancy by the directors of a corporation, the directors then in
office who have been elected by the corporation's shareholders constitute less
than a majority of the directors then in office, then: (i) any holder of more
than 5% of the corporation's voting stock may call a special meeting of
shareholders, or (ii) the superior court of the appropriate county may order a
special meeting of the shareholders to elect the entire board of directors of
the corporation. The Artecon Bylaws provide that the shareholders may elect a
director at any time to fill any
 
                                       127
<PAGE>   143
 
vacancy not filled by the directors. Any such election by written consent, other
than to fill a vacancy created by removal, requires the consent of a majority of
the outstanding shares entitled to vote. Any such election by written consent to
fill a vacancy created by removal requires the consent of all of the outstanding
shares entitled to vote.
 
     Payment of Dividends. The DGCL permits a corporation to declare and pay
dividends out of statutory 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 capital represented by the issued and outstanding stock of
all classes having a preference upon the distribution of assets. In addition,
the DGCL generally provides that a corporation may redeem or repurchase its
shares only if such redemption or repurchase would not impair the capital of the
corporation. The Storage Dimensions Bylaws provide for the declaration and
payment of dividends in accordance with the DGCL. Under the CGCL, any dividends
or other distributions to shareholders, such as redemptions, are limited to the
greater of (i) retained earnings or (ii) an amount which would leave the
corporation with assets (excluding certain intangible assets) equal to at least
125% of its liabilities (excluding certain deferred items) and current assets
equal to at least 100% (or, in certain circumstances, 125%) of its current
liabilities.
 
     Appraisal Rights. Under both the DGCL and the CGCL, a shareholder of a
corporation participating in certain major corporate transactions may, under
varying circumstances, be entitled to appraisal (or dissenters') 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 the DGCL, such 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 designated as a national market system security
on an interdealer quotation system by the National Association of Securities
Dealers, Inc. or are held of record by more than 2,000 holders if such
stockholders receive only shares of the surviving corporation or shares of any
other corporation which are either listed on a national securities exchange or
designated as a national market system security on an interdealer quotation
system by the National Association of Securities Dealers, Inc. or held of record
by more than 2,000 holders, plus cash in lieu of fractional shares, or (c) to
stockholders of a corporation surviving a merger if no vote of the stockholders
of the surviving corporation is required to approve the merger because the
merger agreement does not amend the existing certificate of incorporation, each
share of the surviving corporation outstanding prior to the merger is an
identical outstanding or treasury share after the merger, and the number of
shares to be issued in the merger does not exceed 20% of the shares of the
surviving corporation outstanding immediately prior to the merger and if certain
other conditions are met.
 
     In connection with the Merger, holders of Artecon Common Stock and Artecon
Preferred Stock may, by complying with Chapter 13 of the CGCL, be entitled to
dissenters' rights as set forth therein, and the shares of Artecon Common Stock
and/or Artecon Preferred Stock held by such persons will be deemed to be
dissenting shares. A copy of Chapter 13 of the CGCL is attached as Annex D to
this Joint Proxy Statement/Prospectus. For a more complete description of such
rights, see "THE MERGER -- Appraisal and Dissenters' Rights."
 
     Inspection of Books and Records. Under the DGCL, any stockholder may
inspect, for any proper purpose, a company's stock ledger, a list of its
stockholders and any other books and records. Under the CGCL, a shareholder or
shareholders holding at least 5% in aggregate of the outstanding voting shares
of a corporation or who hold at least 1% of those voting shares and have filed a
Schedule 14A with the Exchange Commission, shall have the absolute right to do
either or both of the following: (i) inspect and copy the record of
shareholders' names and addresses and shareholdings during usual business hours
upon five days' prior written demand upon the corporation, or (ii) obtain from
the transfer agent for the corporation, upon written demand and upon tender of
its usual charges for such a list, a list of shareholders' names and addresses,
who are entitled to vote for election of directors and their shareholdings, as
of the most recent record date for which it has been compiled or as of a date
specified by the shareholder subsequent to the date of demand.
 
     Limitation of Liability of Directors. The laws of both Delaware and
California permit corporations to adopt a provision in their certificate of
incorporation or articles of incorporation, respectively, eliminating, with
certain exceptions, the personal liability of a director to the corporation or
its shareholders for monetary
 
                                       128
<PAGE>   144
 
damages for breach of the director's fiduciary duty as a director. Under the
DGCL, Storage Dimensions 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 a knowing violation of law; (c) unlawful dividends, stock
repurchases or redemptions; or (d) transactions from which the director received
an improper personal benefit. Such limitation of liability provision also may
not limit a director's liability for violation of, or otherwise relieve
directors from the necessity of complying with federal or state securities laws,
or affect the availability of nonmonetary remedies such as injunctive relief or
rescission. The Storage Dimensions Certificate eliminates the liability of the
Storage Dimensions Board to the fullest extent permissible under the DGCL.
 
     The CGCL 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 any
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 have
been 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; or (g)
liability for improper distributions, loans or guarantees.
 
     Indemnification. The DGCL generally permits indemnification of expenses
incurred in the defense or settlement of a derivative or third-party action,
provided there is a determination by a disinterested quorum of the directors, by
independent legal counsel or by the stockholders, that the person seeking
indemnification acted in good faith and in a manner reasonably believed to be in
or (in contrast to the CGCL) not opposed to the best interests of the
corporation and, with respect to a criminal proceeding, which such person had no
reasonable cause to believe his or her conduct was unlawful. Without court
approval, however, no indemnification may be made in respect of any derivative
action in which such person is adjudged liable to the corporation. The DGCL
requires indemnification of expenses when the individual being indemnified has
successfully defended the action on the merits or otherwise. The Storage
Dimensions Bylaws provide that Storage Dimensions will indemnify its directors
and executive officers and may indemnify other offices to the fullest extent
permitted by law. Under the Storage Dimensions Bylaws, indemnified parties are
entitled to indemnification of negligence, gross negligence and otherwise to the
fullest extent permitted by law. The Storage Dimensions Bylaws also require
Storage Dimensions to advance litigation expenses in the case of stockholder
derivative actions or other actions, against an undertaking by the indemnified
party to repay such advances if it is ultimately determined that the indemnified
party is not entitled to indemnification. Storage Dimensions also has
indemnification agreements with its executive officers and directors.
 
     In addition, under the Reorganization Agreement, Storage Dimensions has
agreed that, from and after the consummation of the Merger, it will fulfill and
honor in all material respects the obligations of Storage Dimensions and Artecon
pursuant to (i) each indemnification agreement in effect at such time between
Storage Dimensions and each person who is or was a director or officer of
Storage Dimensions and Artecon at or prior to the Effective Time and (ii) any
indemnification provisions under Storage Dimensions' Certificate of
Incorporation or Artecon's Articles of Incorporation or either company's Bylaws,
as each was in effect on the date of the Reorganization Agreement. Pursuant to
the Reorganization Agreement, Storage Dimensions has also agreed that the
companies' respective charter documents will continue to contain the provisions
with respect to indemnification and exculpation from liability set forth in such
documents as of the date of the Reorganization Agreement and such provisions
will not be amended, repealed or otherwise modified for a period of six years
after the Effective Time in any manner that would adversely affect the rights
thereunder of any Indemnified Party.
 
     The CGCL 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 indemnity for
expenses, and then such indemnification may be made only
 
                                       129
<PAGE>   145
 
to the extent that such court shall determine, and (b) no indemnification may be
made without court approval in respect of amounts paid in settling or otherwise
disposing of an action or expenses incurred in defending an action which is
settled or otherwise disposed of without court approval.
 
     Indemnification is permitted by the CGCL only for acts taken by the person
seeking indemnification in good faith and believed to be in the best interests
of the corporation and its shareholders and with respect to a criminal
proceeding, which such person had no reasonable cause to believe his conduct was
unlawful, as determined by a majority vote of a quorum of disinterested
directors, independent legal counsel (if a quorum of disinterested directors is
not obtainable), a majority vote of a quorum of the shareholders (excluding
shares owned by the indemnified party), or the court handling the action. The
CGCL requires indemnification when the individual has successfully defended the
action on the merits. California corporations may include in their articles of
incorporation a provision which extends the scope of indemnification through
agreements, bylaws or other corporate actions beyond that specifically
authorized by law. The Artecon Bylaws include a provision that provides Artecon
with the authority to indemnify its agents to the fullest extent permitted by
the CGCL.
 
     Stockholder Approval of Certain Business Combinations. Section 203 of the
DGCL prohibits a corporation from engaging in a "business combination" with an
"interested stockholder" for three years following the date that such person
becomes an interested stockholder. With certain exceptions, an interested
stockholder is a person or entity who or which owns 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 of 15% or more of such voting stock at any time
within the previous three years.
 
     For purposes of Section 203, the term "business combination" is defined
broadly to include mergers of the corporation or a subsidiary with or caused by
the interested stockholder; sales or other dispositions of the interested
stockholder (except proportionately with the corporation's other stockholders)
of assets of the corporation or a subsidiary equal to ten percent or more of the
aggregate market value of the corporation's consolidated assets or its
outstanding stock; the issuance or transfer by the corporation or a 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 ownership of any class or series of the
corporation's or such subsidiary's stock); or receipt by the interested
stockholder (except proportionately as a stockholder), directly or indirectly,
of any loans, advances, guarantees, pledges 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 at which such stockholder becomes an
interested stockholder the board of directors approves either the business
combination or the transaction which resulted in the person becoming an
interested shareholder; (ii) the interested stockholder owns 85% of the
corporation's voting stock upon consummation of the transaction which made him
or her an interested stockholder (excluding from the number of shares
outstanding those shares owned by directors who are also officers of the target
corporation and shares held by employee stock plans which do not permit
employees to decide confidentially whether to accept a tender or exchange
offer); or (iii) on or after the date such person becomes an interested
stockholder, the board approves the business combination and it is also approved
at a stockholder meeting by 66 2/3% of the voting stock not owned by the
interested stockholder. Section 203 does not apply if the business combination
is proposed prior to the consummation or abandonment of and subsequent to the
earlier of the public announcement or a 20-day notice required under Section 203
of the proposed transaction which (i) constitutes certain (a) mergers or
consolidations, (b) sales or other transfers of assets having an aggregate
market value equal to 50% or more of the aggregate market value of all of the
assets of the corporation determined on a consolidated basis or the aggregate
market value of all the outstanding stock of the corporation, or (c) proposed
tender or exchange offer for 50% or more of the corporation's outstanding voting
stock; (ii) is with or by a person who was either not an interested stockholder
during the last three years or who became an interestedstockholder with the
approval of the corporation's board of directors; and (iii) is approved or not
 
                                       130
<PAGE>   146
 
opposed by a majority of the board members elected prior to any person becoming
an interested stockholder during the previous three years (or their chosen
successors).
 
     Under California law, there is no equivalent provision to Section 203 of
the DGCL. Under Section 1203 of the CGCL, certain business combinations with
certain interested shareholders are subject to specified conditions, including a
requirement that a fairness opinion must be obtained and delivered to the
corporation's shareholders. The CGCL requires that holders of a California
corporation's common stock receive nonredeemable common stock in a merger of the
corporation with the holder (or an affiliate of the holder) of more than 50% but
less than 90% of its common stock, unless all of the holders of its common stock
consent to the transaction.
 
     Stockholder Voting on Mergers and Similar Transactions. The laws of both
California and Delaware generally require that a majority of the stockholders of
both acquiring and target corporations approve statutory mergers. The DGCL 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 stock of the surviving corporation outstanding before the
merger is an identical outstanding or treasury share after the merger, and (c)
the number of shares to be issued by the surviving corporation in the merger
does not exceed 20% of the shares outstanding immediately prior to the merger.
The CGCL contains a similar exception to its voting requirements for
reorganization where shareholders or the corporation itself, or both,
immediately prior to the reorganization will own immediately after the
reorganization equity securities constituting of more than five-sixths of the
voting power (assuming the conversion of convertible equity securities) of the
surviving or acquiring corporation or its parent entity.
 
     The laws of both California and Delaware also generally require that a sale
of all or substantially all of the assets of a corporation be approved by a
majority of the voting shares of the corporation transferring such assets.
 
     With certain exceptions, the CGCL also requires that mergers,
reorganizations, and similar transactions be approved by a majority vote of each
class of shares outstanding. In contrast, the DGCL generally does not require
class voting, except for amendments to the certificate of incorporation that
change the number of authorized shares or the par value of shares of a specific
class or that adversely affect such class of shares.
 
     Loans to Directors, Officers and Employees. The DGCL permits Storage
Dimensions to make loans to, guarantee the obligations of, or otherwise assists
its officers or other employees when such action, in the judgment of the
directors, may reasonably be expected to benefit Storage Dimensions. Under the
CGCL, any loan to or guaranty for the benefit of a director or officer,
including pursuant to an employee benefit plan, of the corporation requires
approval of holders of a majority of the outstanding shares of the corporation.
However, the CGCL provides that if Artecon has 100 or more shareholders of
record and has adopted a bylaw allowing the Artecon Board to do so, the Artecon
Board alone may approve loans to or guaranties on behalf of an officer (whether
or not such officer is a director) or adopt an employee benefit plan authorizing
such loans or guarantees, by a vote sufficient without counting the vote of any
interested director or directors, if the Artecon Board determines that any such
loan, guaranty or plan may reasonably be expected to benefit the corporation.
 
     Interested Director Transactions. Under the laws of both California and
Delaware, contracts or transactions between a corporation and one or more of its
directors or between a corporation and any other entity in which one or more of
its directors are directors or have a financial interest, are not void or
voidable because of such interest or because such director is present at a
meeting of the board which authorizes or approves the contract or transaction,
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 the CGCL and the DGCL.
Under the CGCL and the DGCL, either (a) the shareholders or the board of
directors must approve any such contract or transaction in good faith after full
disclosure of the material facts (and, in the case of board approval other than
for a common directorship, the CGCL requires that the contract or transaction
must also be "just and reasonable" to the corporation), or (b) the contract or
transaction must have been "fair" (in Delaware) or, in the case of a common
directorship (in California), "just and reasonable" as to the corporation at the
time it was approved. The CGCL explicitly
 
                                       131
<PAGE>   147
 
places the burden of proof of the just and reasonable nature of the contract or
transaction on the interested director.
 
     Under the DGCL, if board approval is sought, the contract or transaction
must be approved by a majority of the disinterested directors (even though less
than a majority of a quorum). Under the CGCL, if shareholder approval is sought,
the interested director is not entitled to vote his or her 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).
 
     Stockholder Derivative Suit. Under the DGCL, a person may only bring a
derivative action on behalf of the corporation if the person was a stockholder
of the corporation at the time of the transaction in question or his or her
stock thereafter devolved upon him or her by operation of law. The CGCL 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 criteria are met. The CGCL also provides that the corporation or
the defendant in a derivative suit may, under certain circumstances, 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.
 
     Dissolution. Under the DGCL, if the dissolution is initiated by the board
of directors it may be approved by the holders of a majority of the
corporation's shares. If the board of directors does not approve the proposal to
dissolve, it must be consented to in writing by all stockholders entitled to
vote thereon. Under the CGCL, 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. The board may
cause the corporation to dissolve if (a) an order for relief under Chapter 7 of
the Federal bankruptcy law has been entered, (b) no shares have been issued or
(c) the corporation has disposed of all of its assets and has not conducted any
business for a period of five years preceding the adopting of a resolution to
dissolve.

                    ADDITIONAL MATTERS FOR CONSIDERATION BY
                        STORAGE DIMENSIONS STOCKHOLDERS
 
                  THE CERTIFICATE OF INCORPORATION AMENDMENTS
 
GENERAL
 
     On December 22, 1997, the Storage Dimensions Board unanimously adopted,
subject to stockholder approval, the Certificate of Amendment to Storage
Dimensions' Amended and Restated Certificate of Incorporation set forth in Annex
B, which includes two amendments to Storage Dimensions' Amended and Restated
Certificate of Incorporation: (i) an amendment to provide for a classified Board
of Directors whereby the directors will be separated into three classes with
members of each class serving for a three year term and (ii) an amendment to
provide that a director may not be removed from office without cause except,
until the third annual meeting of Storage Dimensions following the Merger, by
the affirmative vote of at least 80% of the outstanding voting stock of Storage
Dimensions and by the affirmative vote of at least 66 2/3% of the outstanding
voting stock of Storage Dimensions thereafter. Both amendments were adopted as
part of the terms of the Merger approved by the Storage Dimensions Board at the
time the Merger was approved.
 
     The purpose of the proposed amendments is to give Storage Dimensions
adequate time to negotiate with potential acquirors which make unsolicited
offers to buy Storage Dimensions. Storage Dimensions believes that acquisition
proposals that the Storage Dimensions Board cannot effectively evaluate can
seriously disrupt the business and management of Storage Dimensions and
generally present to stockholders the risk of terms which may be less than
favorable to all of the stockholders than would be available in a Board-approved
transaction. In particular, Board-approved transactions may be carefully planned
and undertaken at an opportune time in order to obtain maximum value for Storage
Dimensions and all of its stockholders with due consideration to matters such as
the recognition or postponement of gain or loss for tax purposes, the management
and business of the acquiring entity and maximum strategic deployment of
corporate assets. Since the effect of the Certificate of Incorporation
Amendments is to make management more difficult to remove involuntarily, the
Certificate of Incorporation Amendments may force those seeking to assume
control of Storage Dimensions to negotiate with management which may lead to a
more favorable price for stockholders in any transaction to assume control.
 
     However, the overall effect of the Certificate of Incorporation Amendments
is to make more difficult the acquisition of Storage Dimensions without the
support of its Board. The effect of making removal of management more difficult
may be the continuation of management tenure even if the removal of management
is desired by more than a majority of the stockholders and would be beneficial
to the stockholders.
 
     The Storage Dimensions Board has considered the potential disadvantages and
has unanimously concluded that the potential benefits of the proposed
Certificate of Incorporation Amendments outweigh the possible disadvantages. The
Certificate of Incorporation Amendments are part of a plan by the Storage
Dimensions Board of Directors to ensure that Storage Dimensions, its management
and the stockholders are protected to the maximum extent possible from the
negative effects of an unapproved change in control of Storage Dimensions.
 
     The Certificate of Incorporation Amendments are discussed more fully in
Proposal 2 and Proposal 3 below and are set forth in the Certificate of
Amendment attached as Annex B to this Joint Proxy Statement/Prospectus.
 
     PROPOSAL 2 AND PROPOSAL 3 ARE MUTUALLY DEPENDENT. THAT IS, A VOTE AGAINST
PROPOSAL 2 WILL CONSTITUTE A VOTE AGAINST PROPOSAL 3 AND A VOTE AGAINST PROPOSAL
3 WILL CONSTITUTE A VOTE AGAINST PROPOSAL 2. FURTHERMORE, A VOTE AGAINST THE
BUSINESS COMBINATION PROPOSAL BY THE STORAGE DIMENSIONS' STOCKHOLDERS WILL
CONSTITUTE A VOTE AGAINST BOTH PROPOSAL 2 AND PROPOSAL 3. IN THE EVENT THE
STORAGE DIMENSIONS STOCKHOLDERS DO NOT APPROVE PROPOSAL 2 AND PROPOSAL 3, THE
PROPOSED CERTIFICATE OF AMENDMENT WILL BE REVISED TO DELETE THE PROVISIONS
RELATED TO PROPOSAL 2 AND PROPOSAL 3.

                                   PROPOSAL 2
 
                  APPROVAL OF AMENDMENT TO STORAGE DIMENSIONS'
                 CERTIFICATE OF INCORPORATION TO PROVIDE FOR A
                         CLASSIFIED BOARD OF DIRECTORS
 
     Stockholders are requested in this Proposal 2 to specifically approve the
amendment to the Storage Dimensions Certificate of Incorporation to add Section
2 to Article VII of Storage Dimensions' Certificate of Incorporation, which
amendment provides for a classified Board of Directors whereby the directors
will be separated into three classes with members of each class serving for a
three-year term.
 
     Currently, each elected director of Storage Dimensions holds office until
the next annual meeting of stockholders and until his or her successor is duly
elected and qualified. The proposed amendment to add Section 2 to Article VII of
the Storage Dimensions' Certificate of Incorporation provides for a classified
Board of Directors with staggered three-year terms. Directors will be assigned
to one of three classes designated as Class I, Class II and Class III,
respectively, by resolution of the Board of Directors. The Board of Directors
will have the authority to reallocate directors among classes from time to time,
and to appoint new directors to any class, so long as the total number of
directors in each class remains equal as nearly as practicable. The term of
office of Class I directors will expire on the first annual meeting of
stockholders of Storage Dimensions following the adoption of the Certificate of
Amendment, while the terms of Class II and Class III directors expire on the
second and third annual meetings, respectively, following adoption of the
Certificate of Amendment. If adopted, the provision would be applicable to every
subsequent election of directors and have the effect of requiring at least two
annual meetings to gain control of the Board of Directors versus only one annual
meeting under the current system.
 
     Approval of Proposal 2 will require the affirmative vote of the holders of
a majority of the outstanding voting stock of Storage Dimensions. Accordingly,
abstentions and broker non-votes are equivalent to negative votes for purposes
of approving Proposal 2. A vote against this Proposal 2 will constitute a vote
against Proposal 3.
 
     THE STORAGE DIMENSIONS BOARD BELIEVES THAT APPROVAL OF THIS PROPOSAL 2 IS
IN THE BEST INTERESTS OF STORAGE DIMENSIONS AND ITS STOCKHOLDERS AND UNANIMOUSLY
RECOMMENDS THAT THE STORAGE DIMENSIONS STOCKHOLDERS VOTE IN FAVOR OF PROPOSAL 2.
 
                                   PROPOSAL 3
 
                        APPROVAL OF AMENDMENT TO STORAGE
                    DIMENSIONS' CERTIFICATE OF INCORPORATION
                         REGARDING REMOVAL OF DIRECTORS
 
     Stockholders are requested in this Proposal 3 to specifically approve the
amendment to add Section 3 to Article VII of Storage Dimensions' Certificate of
Incorporation, which amendment provides that a director may not be removed from
office without cause except, until the third annual meeting of Storage
Dimensions following the Merger, by the affirmative vote of at least 80% of the
outstanding voting stock of Storage Dimensions and by the affirmative vote of at
least 66 2/3% of the outstanding voting stock of Storage Dimensions thereafter.
 
     Under Delaware law and the current Storage Dimensions Certificate of
Incorporation, any director or the entire Board of Directors of a non-classified
board (i.e., a Board of Directors such as Storage Dimensions' which is not split
into multiple classes) may be removed from office with or without cause by the
affirmative vote of the holders of a majority of the outstanding voting stock of
the company. However, under Delaware law, unless provided in the company's
certificate of incorporation, a director of a classified board (i.e., a Board of
Directors split into three classes as set forth in Proposal 2) may be removed
only for cause by the affirmative vote of the holders of a majority of the
outstanding voting stock of the company. The proposed amendment to add Section 3
to Article VII of the Storage Dimensions Certificate of Incorporation will
permit the removal of a director (i) with cause only upon the affirmative vote
of the holders of a majority of the outstanding voting stock of Storage
Dimensions or (ii) without cause by (A) until the third annual meeting of
 
                                       134
<PAGE>   150
 
Storage Dimensions following the Merger, the affirmative vote of at least 80% of
the outstanding voting stock of Storage Dimensions and (B) after the third
annual meeting of Storage Dimensions following the Merger, the affirmative vote
of at least 66 2/3% of the outstanding voting stock of Storage Dimensions.
 
     Approval of Proposal 3 will require the affirmative vote of the holders of
a majority of the outstanding voting stock of Storage Dimensions. Accordingly,
abstentions and broker non-votes are equivalent to negative votes for purposes
of approving Proposal 3. A vote against this Proposal 3 will constitute a vote
against Proposal 2.
 
     THE STORAGE DIMENSIONS' BOARD BELIEVES THAT APPROVAL OF THIS PROPOSAL 3 IS
IN THE BEST INTERESTS OF STORAGE DIMENSIONS AND ITS STOCKHOLDERS AND UNANIMOUSLY
RECOMMENDS THAT THE STORAGE DIMENSIONS STOCKHOLDERS VOTE IN FAVOR OF PROPOSAL 3.
 
                                   PROPOSAL 4
 
                             APPROVAL OF AMENDMENT
                           TO 1996 STOCK OPTION PLAN
 
     Storage Dimensions stockholders are also being asked to approve at the
Storage Dimensions Special Meeting an amendment to the Storage Dimensions 1996
Stock Option Plan (the "1996 Option Plan") to increase the number of shares
which may be issued under the 1996 Option Plan from 1,000,000 to 3,000,000. As
of December 31, 1997, there were options outstanding to purchase 805,831 shares
of Storage Dimensions Common Stock and 194,169 shares remained available for
future grant under the 1996 Option Plan. The Storage Dimensions Board approved
the amendment in January 1998 in order to ensure that following the Merger,
Storage Dimensions has an option pool sufficient to attract and retain qualified
personnel.
 
DESCRIPTION OF THE 1996 OPTION PLAN
 
     The material features of the 1996 Option Plan are outlined below.
 
GENERAL
 
     The 1996 Option Plan provides for the grant of nonqualified stock options
only, which are not intended to qualify as "incentive stock options" under the
Code. See "-- Federal Income Tax Information" for a discussion of the tax
treatment of nonqualified stock options.
 
PURPOSE
 
     The 1996 Option Plan was adopted to provide a means for selected officers
and employees of and consultants to Storage Dimensions and its affiliates to be
given an opportunity to purchase stock in Storage Dimensions, to assist in
retaining the services of employees holding key positions, to secure and retain
the services of persons capable of filling such positions, and to provide
incentives for such persons to exert maximum efforts for the success of Storage
Dimensions.
 
ADMINISTRATION
 
     The 1996 Option Plan provides that it will be administered by the Storage
Dimensions Board and authorizes the Board to delegate such administration to a
committee of two or more directors, each of whom shall be disinterested within
the meaning of Rule 16b-3 under the Exchange Act. As used herein with respect to
the 1996 Option Plan, the "Storage Dimensions Board" refers to the Compensation
Committee as well as the Storage Dimensions Board itself. The Storage Dimensions
Board has the power to construe and interpret the 1996 Option Plan and, subject
to the provisions of the 1996 Option Plan, to determine the persons to whom and
the dates on which options will be granted, the number of shares to be subject
to each option, the time or times during the term of each option within which
all or a portion of such option may be exercised, the exercise price, the type
of consideration, and other terms of the option. The Storage Dimensions Board
has delegated such administration to the Compensation Committee.
 
                                       135
<PAGE>   151
 
ELIGIBILITY
 
     Nonqualified stock options may be granted under the 1996 Option Plan only
to employees (including officers) and directors of, or consultants to, Storage
Dimensions or its affiliates.
 
STOCK SUBJECT TO THE 1996 OPTION PLAN
 
     If options granted under the 1996 Option Plan expire or otherwise terminate
without being exercised, the Storage Dimensions Common Stock not purchased
pursuant to such options again becomes available for issuance under the 1996
Option Plan. The current number of shares authorized for issuance under the 1996
Option Plan is 1,000,000 shares. Under this proposal, the 1996 Option Plan would
be amended to increase the number of shares authorized for issuance to
3,000,000.
 
TERMS OF OPTIONS
 
     The following is a description of the permissible terms of options under
the 1996 Option Plan. Individual option grants may be more restrictive as to any
or all of the permissible terms described below.
 
     Exercise Price; Payment. The exercise price of nonqualified options under
the 1996 Option Plan may not be less than 85% of the fair market value of the
Storage Dimensions Common Stock subject to the option on the date of the option
grant. In the event of a decline in the value of Storage Dimensions Common
Stock, the Storage Dimensions Board has the authority to offer employees the
opportunity to replace outstanding higher-priced options, whether incentive or
nonqualified, with new lower-priced options.
 
     The exercise price of options granted under the 1996 Option Plan must be
paid either: (i) in cash at the time the option is exercised; or (ii) at the
discretion of the Storage Dimensions Board, (a) by delivery of other Storage
Dimensions Common Stock, (b) pursuant to a deferred payment arrangement, or (c)
in any other form of legal consideration acceptable to the Storage Dimensions
Board.
 
     Option Exercise. Options granted under the 1996 Option Plan may become
exercisable in cumulative increments ("vest") as determined by the Storage
Dimensions Board. Shares covered by options may be subject to different vesting
terms. The Storage Dimensions Board has the power to accelerate the time during
which an option may be exercised. In addition, options granted under the 1996
Option Plan may permit exercise prior to vesting, but in such event the optionee
may be required to enter into an early exercise stock purchase agreement that
allows Storage Dimensions to repurchase shares not yet vested should the
optionee leave the employ of Storage Dimensions before vesting.
 
     Term. The maximum term of options under the 1996 Option Plan is ten years.
Options under the 1996 Option Plan terminate three months after the end of
optionee's status as an employee or consultant of Storage Dimensions, or twelve
months after such optionee's termination by death or disability, but in no event
later than the expiration of the option's term. Individual options by their
terms may provide for exercise within a longer or shorter period of time
following termination of employment or the consulting relationship.
 
     Transferability. Options granted under the 1996 Option Plan are not
generally transferable by the optionee, and each option is generally exercisable
during the lifetime of the optionee only by such optionee.
 
ADJUSTMENT PROVISIONS
 
     If there is any change in the stock subject to the 1996 Option Plan or
subject to any option granted under the 1996 Option Plan (through consolidation,
reorganization, recapitalization, stock dividend, stock split, combination of
shares, or otherwise), the 1996 Option Plan and options outstanding thereunder
will be appropriately adjusted as to the class and the maximum number of shares
subject to the 1996 Option Plan and the class, number of shares, and price per
share of stock subject to such outstanding options.
 
     As to options currently outstanding under the 1996 Option Plan, the 1996
Option Plan provides that, in the event of a change in control in which the
current stockholders of Storage Dimensions own less than 50% of the surviving
company or a sale of all or substantially all of Storage Dimensions' assets,
each optionee will have the right to exercise the option as to all of the
optioned stock, including shares as to which the option would not otherwise be
exercisable. If an option becomes exercisable in full in the event of a merger
or sale of assets, Storage Dimensions will notify the optionee that the option
will be fully exercisable for a specified
 
                                       136
<PAGE>   152
 
period from the date of such notice, and the option will terminate upon the
expiration of such period. As to all options granted after December 22, 1997
under the 1996 Option Plan, such options shall be assumed or substituted by the
successor company and if not so assumed or substituted, shall terminate upon

FEDERAL INCOME TAX INFORMATION
 
     Nonqualified stock options granted under the 1996 Option Plan generally
have the following federal income tax consequences:
 
     There are no tax consequences to the optionee or Storage Dimensions by
reason of the grant of a nonqualified stock option. Upon exercise of a
nonqualified stock option, the optionee normally will recognize taxable ordinary
income equal to the excess of the stock's fair market value on the date of
exercise over the option exercise price. Generally, with respect to employees,
Storage Dimensions is required to withhold from regular wages or supplemental
wage payments an amount based on the ordinary income recognized. Subject to the
requirement of reasonableness, the provisions of Section 162(m) of the Code and
the satisfaction of any withholding obligation, Storage Dimensions will
generally be entitled to a business expense deduction equal to the taxable
ordinary income realized by the optionee. Pursuant to Section 162(m) of the
Code, Storage Dimensions' business expense deduction will be limited to $1
million for certain executive employees if such an employee's recognition of
ordinary income, combined with all other compensation paid to the employee
during the year of such recognition, exceeds $1 million. Upon disposition of the
stock, the optionee will recognize a capital gain or loss equal to the
difference between the selling price and the sum of the amount paid for such
stock plus any amount recognized as ordinary income upon exercise of the option.
Such gain or loss will be long- or short-term depending on whether the stock was
held for more than one year. Slightly

repurchase options or who are subject to Section 16(b) of the Exchange Act.
 
     THE STORAGE DIMENSIONS BOARD OF DIRECTORS HAS UNANIMOUSLY RECOMMENDED A
VOTE FOR APPROVAL OF THE AMENDMENT TO STORAGE DIMENSIONS' 1996 STOCK OPTION
PLAN.
 
                                   PROPOSAL 5
                             APPROVAL OF AMENDMENT
                      TO 1996 EMPLOYEE STOCK PURCHASE PLAN
 
     The Storage Dimensions stockholders are also being asked to approve an
amendment of Storage Dimensions' 1996 Employee Stock Purchase Plan (the
"Purchase Plan") to increase the number of shares which may be issued under the
Purchase Plan from 200,000 to 400,000. As of December 31, 1997, 47,253 shares of
Storage Dimensions Common Stock had been purchased under the Purchase Plan and
152,747 shares of Storage Dimensions Common Stock remained available for
purchase under the Purchase Plan. The Storage Dimensions Board adopted this
amendment in January 1998 in order to ensure that following the Merger, Storage
Dimensions has sufficient shares authorized under its Purchase Plan to attract
and retain qualified personnel.
 
DESCRIPTION OF THE PURCHASE PLAN
 
     The material features of the Purchase Plan are outlined below.
 
GENERAL
 
     The Purchase Plan provides for the opportunity to purchase Storage
Dimensions Common Stock through accumulated payroll deductions. The Purchase
Plan is intended to qualify as an "Employee Stock Purchase Plan" under Section
423 of the Code.
 
     The Purchase Plan was adopted to provide a means for employees of Storage
Dimensions to be given an opportunity to purchase stock in Storage Dimensions,
to assist in retaining the services of employees, to secure and retain services
of persons capable of filling such positions, and to provide incentives for such
persons to exert maximum efforts for the success of Storage Dimensions.
 
ADMINISTRATION
 
     The Purchase Plan provides that it is to be administered by the Storage
Dimensions Board and authorizes the Board to delegate such administration to a
committee of two or more directors, each of whom shall be disinterested within
the meaning of Rule 16b-3 under the Exchange Act. As used herein with respect to
the Purchase Plan, the "Storage Dimensions Board" refers to the Compensation
Committee as well as the Storage Dimensions Board itself. The Storage Dimensions
Board has the power to construe and interpret the Purchase Plan. The Storage
Dimensions Board has delegated such administration to the Storage Dimensions
Compensation Committee.
 
ELIGIBILITY
 
     Storage Dimensions employees are eligible to participate in the Purchase
Plan if they are customarily employed by Storage Dimensions or any participating
subsidiary for at least 20 hours per week and more than five months in any
calendar year.
 
OFFERING PERIODS
 
     The Purchase Plan has two six-month offering periods each year beginning on
the first trading day on or after August 15 and February 15, respectively, of
each year.
 
PARTICIPATION IN PURCHASE PLAN
 
     An eligible employee may participate in the Purchase Plan by completing a
subscription agreement authorizing payroll deductions, in an amount not
exceeding fifteen percent of such employee's compensation up to a maximum of
$7,500 during the offering period. Participation in the Purchase Plan is
voluntary and is
 
                                       138
<PAGE>   154
 
dependent on each eligible employee's election to participate and his or her
respective determination as to the level of payroll deductions. Accordingly,
future purchases under the Purchase Plan are not determinable. The following
table sets forth, as to the Storage Dimensions Named Executive Officers, all
current executive officers as a group and all other employees who participated
in the Purchase Plan: (i) the number of shares of Storage Dimensions Common
Stock purchased under the Purchase Plan during the last fiscal year; and (ii)
the dollar value of the benefit:

(1) Market value of shares on date of purchase, minus the purchase price under
    the Purchase Plan.
 
PURCHASE PRICE
 
     The purchase price under the Purchase Plan shall be an amount equal to 85%
of the fair market value of a share of Common Stock on the enrollment date or
the exercise date, whichever is lower (subject to any limit imposed by the
Code).
 
ADJUSTMENT PROVISIONS
 
     If there is any change in the stock subject to the Purchase Plan (through
merger, consolidation, reorganization, recapitalization, stock dividend,
dividend in property other than cash, stock split, liquidating dividend,
combination of shares, exchange of shares, change in corporate structure or
otherwise), will be appropriately adjusted as to the class and the maximum
number of shares subject to such plan and the class, number of shares, and price
per share of stock subject to such outstanding options.
 
EFFECT OF CERTAIN CORPORATE EVENTS
 
     The Purchase Plan provides that in the event of a proposed sale of all or
substantially all of the assets of Storage Dimensions, or a merger of Storage
Dimensions with or into another corporation, the offering period then in effect
shall be shortened by setting a new exercise date, which shall be before the
date of Storage Dimensions' proposed sale or merger. The offering period in
effect at the Effective Time will be terminated immediately prior to the
Effective Time and shares of Storage Dimensions Common Stock will be issued
thereunder. Subsequently, a new offering period will commence five days after
the Effective Time and will end at the time provided for in the Purchase Plan.
 
DURATION, AMENDMENT AND TERMINATION
 
     The term of the Purchase Plan shall continue in effect until 2006. The
Storage Dimensions Board may suspend or terminate the Purchase Plan without
stockholder approval or ratification at any time or from time to time. The Board
may also amend the Purchase Plan at any time or from time to time.
 
TRANSFERABILITY
 
     Rights granted under the Purchase Plan are not transferable by a
participant other than by will, the laws of descent and distribution or as
otherwise provided under the Purchase Plan.
 
TAX INFORMATION
 
     The Purchase Plan, and the right of participants to make purchases
thereunder, is intended to qualify under the provisions of Sections 421 and 423
of the Code. Under these provisions, no income will be taxable to a participant
at the time of grant of the option or purchase of shares. Upon disposition of
the shares, the participant will generally be subject to tax and the amount of
the tax will depend upon the holding period.
 
                                       139
<PAGE>   155
 
     If the shares have been held by the participant for more than two years
after the date of option grant and for more than one year after the date of
purchase, the lesser of (a) the excess of the fair market value of the shares at
the time of such disposition over the purchase price or (b) the excess of the
fair market value of the shares at the date of commencement of the offering
period over the exercise price, will be treated as ordinary income. Any further
gain or loss will be taxed as a long-term gain or loss. If the shares are sold
and the sale price is less than the purchase price, there is no ordinary income
and the participant has a capital loss for the difference. If the shares are
disposed of before the expiration of these holding periods, the excess of the
fair market value of the shares on the purchase date over the purchase price
will be treated as ordinary income, and any further gain or loss on such
disposition will be long-term or short-term capital gain or loss, depending on
the holding period.
 
     Different rules may apply with respect to participants subject to Section
16 of the Exchange Act.
 
     Storage Dimensions is not entitled to a deduction for amounts taxed as
ordinary income or capital gain to a participant except to the extent of
ordinary income recognized by participants upon dispositions of shares prior to
the expiration of the holding periods described above.
 
     The foregoing is only a brief summary of the effect of federal income
taxation upon the participant and Storage Dimensions with respect to the shares
purchased under the Purchase Plan, does not purport to be complete, and does not
discuss the tax consequences of a participant's death or the income tax laws of
any municipality, state or foreign country in which a participant may reside.
 
     THE STORAGE DIMENSIONS BOARD HAS UNANIMOUSLY RECOMMENDED A VOTE FOR
APPROVAL OF THE AMENDMENT TO STORAGE DIMENSIONS' 1996 EMPLOYEE STOCK PURCHASE
PLAN.
 
                                 LEGAL MATTERS
 
     The validity of the shares of Storage Dimensions Common Stock and Storage
Dimensions Preferred Stock to be issued in connection with the Merger will be
passed upon for Storage Dimensions by Wilson Sonsini Goodrich & Rosati,
Professional Corporation, Palo Alto, California. Certain corporate and tax
matters related to the Merger will be passed upon for Artecon by Cooley Godward
LLP, San Diego, California.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Shareholders of
Storage Dimensions, Inc.
 
     In our opinion, the accompanying consolidated balance sheet and the related
consolidated statements of operations, stockholders' equity and cash flows
present fairly, in all material respects, the financial position of Storage
Dimensions, Inc. and its subsidiaries at December 31, 1996 and 1997, and the
results of their operations and their cash flows for each of the three years in
the period ended December 31, 1997, in conformity with generally accepted
accounting principles. These financial statements are the responsibility of the
Company's management; our responsibility is to express an opinion on these
financial statements based on our audits. We conducted our audits of these
statements in accordance with generally accepted auditing standards which
require that we plan and perform the audit to obtain reasonable assurance about
whether the financial statements are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, and evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for the opinion expressed above.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
1. THE COMPANY AND ITS SIGNIFICANT ACCOUNTING POLICIES:
 
     Storage Dimensions, Inc. (the "Company") was incorporated in Delaware in
November 1992. The Company designs, manufactures, markets and supports high
performance data storage systems for open systems network applications.
 
     The Company was formed in order to effect a majority interest
management-led buy-out (the "MBO") of Storage Dimensions, Inc. (a wholly owned
subsidiary of Maxtor Corporation ("Maxtor") on December 26, 1992 by an investor
group comprised of members of management and Capital Partners, Inc.
 
     On December 22, 1997 the Company entered into an agreement and Plan of
Merger and Reorganization with Artecon, Inc. ("Artecon") setting forth the terms
of a merger between the Company and Artecon (the "Merger"). Under the terms of
the Merger, each share of Artecon Common Stock would be converted into the right
to receive approximately 2.16 shares of Storage Dimensions Common Stock and each
share of Artecon Preferred Stock would be converted into the right to receive
one share of Storage Dimensions Preferred Stock, and Artecon would become a
wholly owned subsidiary of Storage Dimensions. For accounting purposes, the
Merger would be treated as a purchase of Storage Dimensions by Artecon since
former holders of Artecon equity securities would hold and have voting power
with respect to approximately 62.5% of the total issued and outstanding voting
capital stock of the combined company, giving effect to the conversion of the
Storage Dimensions Preferred Stock to be issued in the Merger and the exercise
of outstanding Storage Dimensions stock with an exercise price of less than
$3.9375 per share.
 
BASIS OF CONSOLIDATION
 
     The consolidated financial statements include the accounts of the Company
and its subsidiaries after elimination of all significant intercompany accounts
and transactions.
 
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 and
disclosures of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenue and expenses during the period.
Actual results could differ from those estimates.
 
CASH AND CASH EQUIVALENTS
 
     Cash and cash equivalents consist of highly liquid investment instruments
with original maturities of three months or less.
 
INVENTORIES
 
     Inventories are stated at the lower of cost (using the first-in, first-out
method) or market.
 
PROPERTY AND EQUIPMENT
 
     Property, equipment and leasehold improvements are stated at cost.
Depreciation is computed using the straight-line method over the estimated
useful lives of the assets, which range from three to five years. Amortization
of leasehold improvements is computed using the straight-line method over the
shorter of the estimated useful lives of the assets or the remaining lease term.
 
REVENUE RECOGNITION AND PRODUCT WARRANTY
 
     Revenue from product sales is recognized upon shipment.
 
     Certain sales are made to distributors who have limited rights to return
products or obtain credits for pricing changes. The Company accrues for the
estimated costs of sales returns and allowances in the period the related
revenue is recognized.
 
                                       F-7

                            STORAGE DIMENSIONS, INC.
 
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
     Also, the Company provides product warranties, generally for periods of
either three or five years from the date of product sale. The Company provides
for the estimated cost to repair or replace products under warranty arrangements
in the period the related revenue is recognized.
 
RESEARCH AND DEVELOPMENT COSTS
 
     Research and development costs are charged to operations as incurred.
 
SOFTWARE DEVELOPMENT COSTS
 
     To date, the period between achieving technological feasibility and
completion of such software has been short and software development costs
qualifying for capitalization have been insignificant. Accordingly, the Company
has not capitalized any software development costs.
 
ADVERTISING COSTS
 
     Advertising costs are charged to operations as incurred in accordance with
AICPA Statement of Position 93-7, "Reporting on Advertising Costs."
 
FISCAL YEAR
 
     The Company operates and reports financial results on a
fifty-two/fifty-three week fiscal year cycle ending on the Saturday nearest
December 31. The Company also follows a five-four-four week quarterly cycle. For
convenience, the Company presents its fiscal year as ending on December 31.
Fiscal 1995, 1996 and 1997 each contained 52 weeks.
 
ACCOUNTING FOR STOCK-BASED COMPENSATION
 
     The Company accounts for stock-based compensation in accordance with
Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to
Employees." In January 1996, the Company adopted the disclosure requirements of
Statement of Financial Accounting Standards No. 123 ("FAS 123"), "Accounting for
Stock-Based Compensation" (see Note 7).
 
NET INCOME (LOSS) PER SHARE
 
     In December 1997, the Company adopted Statement of Financial Accounting
Standards No. 128 ("FAS 128"), "Earnings per Share." All historical earnings per
share information has been restated as required by FAS 128.
 
     Basic net income (loss) per share is computed using the weighted average
number of common shares outstanding during the periods presented and also gives
retroactive effect to the one-for-four reverse split of all shares of Common
Stock as described in Note 6.
 
     Diluted net income (loss) per share is computed using the weighted average
number of common and common equivalent shares outstanding during the periods
presented assuming the conversion of all shares of the Company's Series A
Convertible Preferred Stock into Common Stock. Per share amounts also give
retroactive effect to the one-for-four reverse split of all shares of Common
Stock (and an adjustment to the conversion price of the Series A Convertible
Preferred Stock) as described in Note 6.

4. SHORT-TERM BORROWINGS:
 
     On May 17, 1996, the Company entered into a Loan and Security Agreement
(the "Agreement") with Congress Financial Corporation, which expires May 16,
1998. Under the revolving line of credit provisions of the Agreement, the
Company may borrow up to $11 million based upon eligible accounts receivable and
inventory. Under the terms of the Agreement, deposits from collections of
accounts receivable are restricted. The Agreement also allows the Company to
borrow up to $1 million for purchases of property and equipment under its
capital expenditure facility and up to $400,000 under its term loan provisions.
Such borrowings reduce the available borrowings under the revolving line of
credit. Borrowings bear interest at the rate of prime plus .75% (9.25% as of
December 31, 1997) and are secured by all of the Company's assets. Borrowings
outstanding under the line at December 31, 1996 and 1997 include $267,000 and
$67,000, respectively, representing borrowings under the term loan provisions.

</TABLE>
 
     The Company provides a valuation allowance for deferred tax assets when it
is more likely than not, based on available evidence including the prior history
of losses, that some or all of the deferred tax assets will not be realized.
 
     At December 31, 1997 the Company had federal net operating loss
carryforwards of approximately $1,410,000 available to reduce future federal and
state taxable income. Its net operating loss carryforwards expire from 2009 to
2012. The tax benefit of the net operating loss and credit carryforwards may be
limited due to the impact of the Tax Reform Act of 1986. Events which may cause

     The fair value of each option grant is estimated on the date of grant using
the minimum value method with the following assumptions used for grants during
the applicable period: dividend yield of 0.0% for both periods; risk-free
interest rates of 5.36% to 6.60% for options granted during the year ended
December 31, 1996 and 5.80% to 6.76% for options granted during the year ended
December 31, 1997; no volatility factor was used due to the nonpublic entity
status for the year ended December 31, 1996 and an 0.80 volatility factor was
used for the year ended December 31, 1997; and a weighted average expected
option term of 5 years for both periods.
 
     Because the determination of the fair value of all options granted after
the Company became a public entity includes an expected volatility factor and
because additional option grants are expected to be made each year, the above
pro forma disclosures are not representative of pro forma effects of reported
net income for future years.
 
8. EMPLOYEE BENEFIT PLANS:
 
Profit sharing
 
     Employees of the Company are entitled to receive compensation under a
profit sharing agreement that is based upon attaining specific profit goals.
Profit sharing expense totaled $20,000, $231,000 and $0 in 1995, 1996 and 1997,
respectively.
 
401(k) Plan
 
     The Company maintains a 401(k) Tax Deferred Savings Plan (the Plan) which
covers all full-time employees of the Company who are at least 21 years of age.
Under the Plan, employees may elect to contribute up to 15% of their pre-tax
compensation to the Plan. The Company matches contributions under the Plan at
the rate of 50% of the employee's contributions up to a specified maximum. The

receivable. Substantially all of the Company's cash is invested in high credit
quality financial institutions. The Company performs ongoing credit evaluations
of its customers' financial conditions and maintains an allowance for
uncollectible accounts receivable based upon expected write-offs. At December

                          INDEPENDENT AUDITORS' REPORT
 
The Board of Directors and Shareholders
Artecon, Inc.
 
     We have audited the accompanying consolidated balance sheet of Artecon,
Inc. and its subsidiaries (the Company) as of March 29, 1997 and December 31,
1997, and the related consolidated statements of operations, shareholders'
equity and cash flows for the year ended March 29, 1997 and the period from
March 30, 1997 to December 31, 1997. These financial statements are the
responsibility of the Company's management. Our responsibility is to express an
opinion on these financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audits to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the consolidated financial statements present fairly, in
all material respects, the consolidated financial position of Artecon, Inc. and
its subsidiaries at March 29, 1997 and December 31, 1997 and the consolidated
results of their operations and their cash flows for the year ended March 29,
1997 and the period from March 30, 1997 to December 31, 1997 in conformity with
generally accepted accounting principles.

 1. DESCRIPTION OF BUSINESS ACTIVITIES
 
     Description of Business -- Artecon, Inc. (the Parent Company) and its
wholly- and majority-owned subsidiaries, Artecon Canada, Inc., Artecon Japan,
Ltd. and Artecon B.V., (collectively the Company or Artecon), are manufacturers
and suppliers of value-added computer products and services in the open systems
workstation and server markets. The subsidiaries purchase finished product from
the parent and resell it in their respective locations. The Company's principal
markets include Canada, Japan, United States and Europe. The Company sells its
products through reseller channels, worldwide government agencies and Fortune
1000 companies.
 
     On August 21, 1997, the Company acquired certain net assets of Falcon
Systems, Inc. (Falcon), a manufacturer and distributor of computer peripheral
equipment. The purchase price of $3,500 included $1,000 in cash and $2,500 of
promissory notes (Note 6). The acquisition was recorded as a purchase and the
results of operations for the period from August 21, 1997 to December 31, 1997
are included in the accompanying consolidated financial statements. The purchase
price was allocated $10,232 to assets acquired (consisting primarily of
inventories, accounts receivable, property and equipment and other current
assets), $638 to goodwill and other intangible assets, $14,138 to liabilities
assumed, and to in-process research and development expenses of $3,700, which
had no future alternative use, based on management assumptions. In connection
with the acquisition, a partnership was created to purchase certain assets from
Falcon. The partners are majority shareholders of the Company. The partnership
is considered to be a Special Purpose Entity and, accordingly, the accompanying
consolidated financial statements include the accounts of the partnership and
all intercompany transactions have been eliminated.
 
     Unaudited pro forma results of operations of the Company for the year ended
March 29, 1997 and the period from March 30, 1997 to December 31, 1997 are
included below. Such pro forma presentation has been prepared assuming that the
acquisition had occurred as of April 1, 1996 for the Company:

</TABLE>
 
     The pro forma results include the historical accounts of the Company and of
Falcon and pro forma adjustments, as may be required, including the in-process
research and development expense, the amortization of goodwill and other
intangible assets, and the interest expense related to the promissory notes
issued to Falcon's previous shareholder. The in process research and development
expense has been included as if recorded on April 1, 1996 and been excluded from
the period from March 30, 1997 to December 31, 1997. The pro forma results of
operations are not necessarily indicative of actual results which may have
occurred had the operations of Falcon been combined in prior years.
 
     On December 22, 1997, the Company entered into an Agreement and Plan of
Merger and Reorganization with Storage Dimensions, Inc. (Storage), setting forth
the terms of a merger between the Company and Storage (the Merger). Under the
terms of the Merger, each share of the Company's common stock would be converted
into the right to receive approximately 2.16 shares of Storage common stock and
each share of the Company's preferred stock would be converted into the right to
receive one share of Storage preferred stock,

                       FOR THE YEAR ENDED MARCH 29, 1997
            AND THE PERIOD FROM MARCH 30, 1997 TO DECEMBER 31, 1997
                    (IN THOUSANDS, EXCEPT PER SHARE AMOUNTS)
 
and the Company would become a wholly-owned subsidiary of Storage. For
accounting purposes, the Merger would be treated as a purchase of Storage by the
Company because former holders of the Company's equity securities would hold and
have voting power with respect to approximately 62.5% of the total issued and
outstanding voting capital stock of the combined company, giving effect to the
conversion of the Storage preferred stock to be issued in the Merger and the
exercise of outstanding Storage stock options with an exercise price of less
than $3.9375 per share.
 
     The Company's fiscal year was previously on a 52-53-week basis that ended
on the Saturday nearest to March 31. The fiscal year ended March 29, 1997
contained 52 weeks. For convenience, effective December 31, 1997, the Company
will present its fiscal year as ending on March 31 and its fiscal quarters as
ending on June 30, September 30 and December 31, respectively.
 
 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     Principles of Consolidation -- The accompanying consolidated financial
statements include the accounts of Artecon and its subsidiaries. All significant
intercompany transactions and balances have been eliminated in consolidation.
 
     Credit Risk -- The Company performs ongoing credit evaluations of its
customers and requires no collateral. The Company maintains reserves for
potential credit losses.
 
     Inventories -- Inventories are comprised of purchased parts and assemblies,
which include direct labor and overhead, and are valued at the lower of cost
(first-in, first-out) or market.
 
     Property and Equipment -- Property and equipment are stated at cost.

     Revenue Recognition -- The Company recognizes revenue from product sales
upon shipment, including products sold under a stock rotation program which
entitles the buyer the right to return products under certain conditions. The
Company provides allowances for estimated returns. Revenue from service
contracts is recognized ratably over the term of the contract.
 
     Revenues derived from various U.S. government agencies were approximately
$1,400 and $754 for the year ended March 29, 1997 and the period from March 30,
1997 to December 31, 1997, respectively. Export sales to international customers
amounted to approximately $7,700 and $5,388 for the year ended March 29, 1997
and the period from March 30, 1997 to December 31, 1997, respectively.
 
     Use of Estimates -- The preparation of financial statements in conformity
with generally accepted accounting principles requires management to make
estimates and assumptions that affect the reported amounts of assets and
liabilities and disclosure of contingent assets and liabilities at the date of
the financial statements and the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.
 
     Income Taxes -- The Company accounts for income taxes in accordance with
SFAS No. 109, Accounting for Income Taxes, which requires recognition of
deferred tax assets and liabilities for the expected future tax consequences of
events that have been included in the financial statements or tax returns. Under
this statement, deferred tax assets and liabilities are determined based on the
difference between the financial statement and tax bases of assets and
liabilities using the enacted tax rates in effect for the year in which the
differences are expected to reverse.
 
     Concentrations -- The Company currently utilizes a limited number of
suppliers for certain devices used in its products but has no long-term supply
contracts with them. Due to the cyclical nature of the industry and competitive
conditions, there can be no assurance that the Company will not experience
difficulties in meeting its supply requirements in the future.
 
     For the year ended March 29, 1997 sales to two customers accounted for
approximately 35% of net revenues. For the period from March 30, 1997 to
December 31, 1997 sales to two customers accounted for approximately 20% of net
revenues. The loss of, or a reduction in sales to, any such customers would have
a material adverse effect on the Company's business, operating results, and
financial condition.
 
     Recent Accounting Pronouncements -- For fiscal years beginning after
December 15, 1997, the Company will adopt SFAS No. 130, Reporting Comprehensive
Income, and SFAS No. 131, Disclosures About Segments of an Enterprise and
Related Information. The Company is reviewing the impact of such statements on
its financial statements.
 
     Reclassifications -- Certain prior year balances have been reclassified to
conform with the current year presentation.

 4. ACCOUNTS AND TRANSACTIONS WITH RELATED PARTIES
 
     Revenues from sales to affiliated companies for the year ended March 29,
1997 and the period from March 30, 1997 to December 31, 1997 were approximately
$74 and $121, respectively. Accounts receivable from affiliated companies were
approximately $7 and $35 at March 29, 1997 and December 31, 1997, respectively,
and are included in accounts receivable in the accompanying consolidated balance
sheets.
 
     The Company purchases certain goods from affiliates and also is subject to
a management fee of approximately $4 per month from an affiliate. Purchases from
affiliated companies for the year ended March 29, 1997 and the period from March
30, 1997 to December 31, 1997 were approximately $85 and $76, respectively.
Certain of these expenses are subject to termination upon the Merger.
 
 5. BORROWINGS UNDER LINE OF CREDIT
 
     The Parent Company has a line of credit agreement with a United States
bank. The agreement, which expires on September 1, 1999, provides for maximum
borrowings of up to $12,500 and is collateralized by substantially all of the
assets of the Company. The Company may choose between borrowing at the bank's
prime rate, as it may vary from time to time, or it may choose a rate that is
fixed for an agreed-upon period of from 30 to 180 days with interest due
quarterly at the LIBOR rate in effect at the commencement of the agreed-upon
fixed period, plus 2.0%. This line of credit agreement requires that the Company
comply with certain covenants, including minimum tangible net worth
requirements. The Company was not in compliance with the cash flow coverage
ratio and financial performance covenants associated with the $9,700 outstanding
under its U.S. bank line for the quarter ended December 31, 1997. The
noncompliance for the quarter was primarily the result of severance costs at
Falcon. The Company obtained a waiver from the bank as of and for the quarter
ended December 31, 1997.
 
     The Japanese subsidiary has three lines of credit with a Japanese bank for
borrowings up to an aggregate 75 million Yen at rates ranging from 1.62% to
2.4%. At December 31, 1997, 60 million Yen (approximately US$460) was
outstanding. Interest is due monthly with the principal due one year from the
commencement of the agreement. Borrowings are collateralized by inventories of
the Japanese subsidiary.
 
     At December 31, 1997, the Company's borrowings under lines of credit were
as follows:

 7. SHAREHOLDERS' EQUITY
 
     There are two classes of preferred shares: the "Preferred" shares and the
"Preferred B" shares. There are 10,000 shares of each preferred class
authorized. All preferred shares are nonvoting, do not provide for dividends,
and have a liquidation preference over common shares. The shares are convertible
into common shares, at the option of the holder, at the earlier of three years
after issuance or upon the occurrence of certain

other events, at the conversion rate of one common share for each 0.8 preferred
share. The liquidation preference for the Preferred is $.01 per share and for
the Preferred B is $2.00 per share.
 
     In December 1994, the Company entered into a repurchase agreement with
certain shareholders who were holders of the Company's outstanding preferred
shares. The agreement required the Company to redeem 100 shares of the
outstanding preferred shares and grants the Company the option to repurchase the
remaining shares at any time during the five-year period ending December 22,
1999 at prices ranging from $2.00 to $2.50 per share. During the year ended
March 29, 1997, the Company repurchased 100 Preferred shares under the agreement
at $2.30 per share.
 
     As consideration for the option to repurchase the preferred shares, in the
period ended December 31, 1997, the Company issued 276 common shares to the
holders of preferred shares at the ratio of approximately one share of common
stock for each ten shares of preferred stock which were valued at $0.50 per
common share. The value ascribed to the common stock outstanding at the date of
issuance has been shown as a reduction in the carrying value of the preferred
stock.
 
     In June and October 1997, the Company issued a total of 95 shares of common
stock to certain employees in exchange for stock participation rights previously
granted. The common stock was issued at prices of $1.20 and $2.00 per share. No
stock participation rights or other options to purchase common stock were
outstanding at December 31, 1997. Management has recorded $73 in compensation
expense in the period from March 30, 1997 to December 31, 1997 as a result of
these issuances.
 
     In July 1997, the Company issued 475 shares of common stock to certain
officers of the Company
at a price of $0.035 per share. Management has recorded $553 in compensation
expense in the period from
March 30, 1997 to December 31, 1997 as a result of these issuances.
 
     In December 1997, the Company adopted SFAS No. 128, "Earnings per Share."
SFAS No. 128 redefines earnings per share under generally accepted accounting
principles. Under the new standard, primary net income per share is replaced by
basic net income per share and fully diluted net income per share is replaced by
diluted net income per share. All historical earnings per share information has
been restated as required by SFAS No. 128.
 
     Basic net income (loss) per share is computed using the weighted average
number of common shares outstanding during the periods presented.
 
     Diluted net income (loss) per share is computed using the weighted average
number of common and common equivalent shares outstanding during the periods
presented assuming the conversion of all shares of the Company's Convertible
preferred stock into common stock. Common equivalent shares have not been
included where inclusion would be antidilutive.

 9. COMMITMENTS
 
     The Company leases office and testing equipment under noncancellable
operating leases. Lease terms range from three to five years. The Company's
United States headquarters is leased under an operating lease that has been
extended to December 1999. The lease provides for rent escalation between a
minimum of 3% and a maximum of 4% on January 1, 1998 and 1999 based on the
consumer price index during the prior year.

     Total rent expense for the year ended March 29, 1997 and the period from
March 30, 1997 to December 31, 1997 was approximately $698 and $675,
respectively.
 
10. HEDGING ACTIVITIES
 
     The Company's Japanese subsidiary enters into derivative financial
instruments, primarily foreign currency forward exchange contracts, to manage
foreign exchange risk on foreign currency transactions and does not use the
contracts for trading purposes. These financial instruments are used to protect
the Company from the risk that the eventual net cash inflows from the foreign
currency transactions will be adversely affected by changes in exchange rates.
Gains and losses related to hedges of firmly committed transactions are deferred
and recognized when the hedged transaction occurs.
 
     The following table summarizes the notional amount, which approximates fair
market value, of the Company's outstanding foreign exchange contracts at
December 31, 1997.

</TABLE>
 
     The counterparties to these instruments are major financial institutions.
The Company is exposed to credit losses in the event of non performance by
counterparties to its forward exchange contracts but has no off-balance sheet
credit risk of accounting loss. The Company anticipates, however, that the
counterparties will be able to fully satisfy their obligations under the
contracts. The Company does not obtain collateral or other security to support
the forward exchange contracts subject to credit risk but monitors the credit
standing of the counterparties.

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS
 
The Board of Directors and Shareholders
Artecon, Inc.
 
     We have audited the accompanying consolidated balance sheets of Artecon,
Inc. at March 30, 1996 and March 25, 1995, and the related consolidated
statements of income, shareholders' equity and cash flows for the years then
ended. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the consolidated financial position of Artecon, Inc.
at March 30, 1996 and March 25, 1995, and the consolidated results of its
operations and its cash flows for the years then ended in conformity with
generally accepted accounting principles.

</TABLE>
 
     Goodwill relates to acquisitions and is being amortized on a straight-line
basis over a period of seven years. Accumulated amortization was $59,850 and
$114,845 at March 30, 1996 and March 25, 1995, respectively. Effective December
31, 1995, the Company terminated the operations of its French subsidiary,
Artecon S.A. and wrote off the remaining $256,397 unamortized balance of
goodwill.
 
     In March 1995, the Financial Accounting Standards Board issued Statement
No. 121, "Accounting for the Impairment of Long-Lived Assets and for Long-Lived
Assets to Be Disposed Of", which requires impairment losses to be recorded on
long-lived assets used in operations when indicators of impairment are present
and the undiscounted cash flows estimated to be generated by those assets are
less than the assets' carrying amount. Statement No. 121 also addresses the
accounting for long-lived assets that are expected to be disposed of. Artecon
plans to adopt Statement No. 121 during fiscal 1997. The financial impact of
adopting Statement No. 121 has not yet been determined.
 
REVENUES
 
     The Company recognizes revenue upon shipment, including products sold under
a stock rotation program which entitles the buyer the right to return products
under certain conditions. The Company provides allowances for estimated returns.
Service contract revenues are recorded as the applicable services are performed
and totaled $450,000 and $375,000 in 1996 and 1995, respectively.
 
     Revenues derived from various U.S. government agencies were approximately
$4.6 million and $1.2 million in 1996 and 1995, respectively. Export sales to
international customers amounted to approximately $11.9 million and $8.9 million
in 1996 and 1995, respectively.
 
USE OF ESTIMATES
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the amounts reported in the financial statements and
accompanying notes. Actual results could differ from those estimates.
 
RECLASSIFICATIONS
 
     Certain prior year balances have been reclassified to conform with the
current year presentation.
 
 2. ACCOUNTS AND TRANSACTIONS WITH RELATED PARTIES
 
     Revenues from sales to affiliated companies during 1996 and 1995 were
approximately $162,000 and $764,000, respectively. Accounts receivable from
affiliated companies were approximately $50,000 and $72,000 at March 30, 1996
and March 25, 1995, respectively and are included in accounts receivable in the
accompanying consolidated balance sheets.

     The Company purchases certain goods from affiliates and also is subject to
a management fee from an affiliate of approximately $4,000 per month. Purchases
from affiliated companies during 1996 and 1995 were approximately $98,000 and
$227,000, respectively. At March 25, 1995 accounts payable to affiliated
companies totaled $26,000 (none in 1996) and are included in accounts payable in
the accompanying consolidated balance sheets.
 
 3. BORROWINGS UNDER LINE OF CREDIT
 
     The Company has a line of credit agreement with a U.S. bank that expires on
September 1, 1997. The agreement provides for maximum borrowings of $4,500,000
and is collateralized by substantially all of the assets of the Company. The
Company may choose between borrowing at the bank's prime rate, as it may vary
from time to time, or it may choose a rate that is fixed for an agreed upon
period of from 30 to 180 days with interest due quarterly at the Eurodollar rate
in effect at the commencement of the agreed upon fixed period, plus 1.5%. This
line of credit agreement requires that the Company maintain certain financial
statement ratios.
 
     The Company's Japanese subsidiary has four lines of credit with a Japanese
bank for borrowings up to an aggregate 70 million Yen ($652,498 at March 30,
1996) at rates ranging from 1.23% to 2.5%. Interest is due monthly with the
balance due six months from the date of the agreement. Borrowings are
collateralized by accounts receivable of the Japanese subsidiary.
 
     At March 30, 1996, the Company's borrowings were as follows:

</TABLE>
 
 4. SHAREHOLDERS' EQUITY
 
     There are two classes of preferred shares, the "Preferred" shares and the
"Preferred B" shares. There are 10,000,000 shares of each preferred class
authorized. The preferred shares are non-voting, do not provide for dividends,
and have a liquidation preference over common shares. The shares are convertible
into common shares, at the option of the holder, at the earlier of three years
after issuance or upon the occurrence of certain other events, at the conversion
rate of one common share for each 0.8 preferred share. The liquidation
preference for the Preferred is $.01 per share, and the Preferred B is $2.00 per
share.
 
     In December 1994, the Company entered into a repurchase agreement with
certain shareholders who were holders of the Company's outstanding preferred
shares. The agreement required the Company to redeem 100,000 shares of the
outstanding preferred shares and grants the Company the option to repurchase the
remaining shares at any time during the five year period ending December 22,
1999 at the prices ranging from $2.00-$2.50 per share. During fiscal 1996 and
1995, the Company repurchased 68,500 and 100,000 preferred shares under the
agreement at $2.20 and $2.00-$2.10 per share, respectively.
 
     As consideration for granting the Company the option to repurchase the
preferred shares, the Company agreed to issue common shares to the holders of
preferred shares at their request at the ratio of one share of common for each
ten shares of preferred stock held prior to any repurchase by the Company at a
price to be determined by the Board of Directors but not less than the fair
value of such shares at the time of repurchase. These common shares are subject
to Company's first right-of-refusal to repurchase any or all of these shares. At
March 30, 1996, no common shares were issued under this agreement.

 5. INCOME TAXES
 
     In accordance with Statement of Financial Accounting Standard No. 109
Accounting for Income Taxes, the Company has reversed its valuation allowance
for deferred tax assets of $845,505 at March 25, 1995 during fiscal year 1996 as
it is deemed to be more likely than not that the Company will be able to realize
such amounts as they become due. Primarily as a result of the reversal of the
valuation allowance, the Company has a net tax benefit of $240,266 during 1996.
 
     Significant components of the provision (benefit) for income taxes are as
follows:

may ultimately assign to these purchased assets and liabilities.
 
USE OF ESTIMATES IN THE PREPARATION OF FINANCIAL STATEMENTS
 
     The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from those estimates.
 
INVENTORIES
 
     Inventories are carried at the lower of moving average cost or market. Cost
elements included in inventory are materials, labor and overhead. Inventory is
mainly comprised of raw material components for all periods.
 
PROPERTY AND EQUIPMENT
 
     Property and equipment are recorded at cost and are depreciated using the
straight-line method with estimated useful lives ranging from 5 to 10 years.
Leasehold improvements are amortized over the lesser of the estimated useful
life of the improvement or the remaining lease term.
 
SOFTWARE DEVELOPMENT COSTS
 
     The Company capitalizes internally developed software costs upon the
establishment of technological feasibility which occurs upon the completion of a
working model. Annual maintenance costs are expensed as incurred unless they
represent substantial improvements. Capitalized software development costs are
included in property and equipment in the accompanying balance sheets and were
$221,071, $197,464 and $50,000 for the period ending August 20, 1997 and the
years ended December 31, 1996 and December 31, 1995, respectively.
 
INCOME TAXES
 
     The Company has elected to be taxed under the provisions of Subchapter S of
the Internal Revenue Code. Under those provisions, the Company does not pay
federal corporate income taxes on its taxable income. Instead, the stockholder
is liable for federal income taxes on the Company's taxable income. The State of
California levies a corporate tax at the rate of 1 1/2% of taxable income. This
tax has been provided for in the general and administrative caption of the
accompanying statements of operations.
 
REVENUE RECOGNITION
 
     Sales of computer equipment are recorded upon shipment, net of an allowance
for estimated returns. The Company maintains a warranty accrual for the
estimated future warranty obligations.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
RESEARCH AND DEVELOPMENT
 
     In accordance with Statement of Financial Accounting Standards (SFAS) No.
2, the Company expenses software research and development costs as they are
incurred. Total research and development costs charged to expense for the year
ended December 31, 1996 were $93,800. For the period ended August 20, 1997 and
the year ended December 31, 1995 research and development costs were immaterial.
 
CONCENTRATION OF CREDIT RISK
 
Credit is extended for all customers based on financial condition and,
generally, collateral is not required. Concentrations of credit risk with
respect to trade receivables are limited due to the large number of customers
comprising the Company's customer base and dispersion across many different
industries and geography. During the year ended December 31, 1996, sales to a
single customer amounted to $6,064,890. During the period ended August 20, 1997
and the year ended December 31, 1995, there were no sales to a single customer
that amount to more than 10% of total revenue.
 
RECLASSIFICATIONS
 
     Certain reclassifications have been made to the 1996 and 1995 balances to
conform to the 1997 presentation.
 
 2. LINE OF CREDIT AND LONG-TERM DEBT
 
     The Company has an $8,000,000 revolving line of credit with a financial
institution with a scheduled expiration of October 2, 1997. This line of credit
is secured by accounts receivable and inventory and bears interest at the bank's
reference rate (8.50% at August 20, 1997) plus .75%. The weighted average
interest rate on the line of credit at August 20, 1997 was 9.15%. At August 20,
1997, the amount outstanding on this line of credit totaled $5,181,756. This
line of credit and the term debt below are guaranteed by the stockholder.
 
     This debt was subject to certain restrictive covenants including
maintaining an acceptable debt to equity ratio, an acceptable current ratio, a
minimum working capital amount, and a minimum tangible net worth. The Company
was in violation of certain restrictive covenants as of August 20, 1997,
December 31, 1996, and December 31, 1995. The debt was paid in full subsequent
to August 20, 1997 and the line of credit was canceled.
 
     Long-term debt consists of:

     Parent, Merger Sub, the Company or any shareholder of the Company:
 
             (i) each share of Company Common Stock outstanding immediately

        Multiple (as defined below) of fully paid and non-assessable shares of
        Parent Common Stock (the "Shares");
 
             (ii) each share of Preferred Stock of the Company outstanding

        fully paid and non-assessable share of Parent Preferred Stock; and
 
             (iii) each share of the Common Stock, $0.001 par value, of Merger
        Sub outstanding immediately prior to the Effective Time shall be
        converted into one share of common stock of the Surviving Corporation.
 
          (b) For purposes of this Agreement:
 
             (i) the term "Applicable Multiple" shall mean a fraction the
        numerator of which is the number of Merger Shares and the denominator of
        which is the number of Company Shares;
 
             (ii) the term "Company Shares" shall mean (A) the number of shares
        of Company Common Stock outstanding immediately prior to the Effective
        Time plus (B) the maximum number of shares of Company Common Stock
        underlying instruments convertible into or exchangeable for Company
        Common Stock (without regard to vesting or similar restrictions)
        outstanding immediately prior to the Effective Time, including shares of
        Company Preferred Stock other than 2,494,159 shares of Company Preferred

        prior to Closing; and
 
             (iii) the term "Merger Shares" shall mean the shares of Parent
        Common Stock to be issued to the Company Shareholders in the Merger and

        number of shares of Parent Common Stock outstanding immediately prior to
        the Effective Time plus (y) the maximum number of shares of Parent
        Common Stock issuable upon exercise, in accordance with their terms but
        without regard to any vesting or similar restrictions, of any and all
        options outstanding as of the date hereof and that are also outstanding
        immediately prior to the Effective Time to purchase Parent Common Stock
        with option exercise prices less than the Applicable Price (defined in
        Section 1.10).
 
                                        2
<PAGE>   212
 
          (c) At the Effective Time, all rights with respect to Company Common
     Stock under Company Options and Company Warrants that are then outstanding,
     if any, shall be converted into and become rights with respect to Parent
     Common Stock, and Parent shall assume each Company Option and Company
     Warrant, if any, in accordance with the terms (as in effect as of the date
     hereof) of the stock option plan or other agreement, as the case may be,
     under which it was issued and the stock option agreement or warrant
     agreement, as the case may be, by which it is evidenced. From and after the
     Effective Time, (i) each Company Option and Company Warrant 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 Company Option and
     Company Warrant shall be equal to the number of shares of Company Common
     Stock subject to such Company Option and Company Warrant immediately prior
     to the Effective Time multiplied by the Applicable Multiple, rounding down
     to the nearest whole share, (iii) the per share exercise price under each
     such Company Option and Company Warrant shall be adjusted by dividing the
     per share exercise price under each such Company Option and Company Warrant
     by the Applicable Multiple and rounding up to the nearest cent and (iv) any
     restriction on the exercise of any Company Option or Company Warrant shall
     continue in full force and effect and the term, exercisability, vesting
     schedule and other provisions of such Company Option and Company Warrant
     shall otherwise remain unchanged; provided, however, that each such Company
     Option and Company Warrant shall, in accordance with its terms, be subject
     to further adjustment as appropriate to reflect any stock split, stock
     dividend, subdivision, reclassification, reorganization, stock split,
     combination or similar transaction subsequent to the Effective Time. The
     Company shall take all action that may be necessary (under the stock option
     plan or other agreements pursuant to which Company Options and Company
     Warrants are outstanding) to effectuate the provisions of this Section
     1.5(c) and to ensure that, from and after the Effective Time, holders of
     Company Options and Company Warrants have no rights with respect thereto
     other than those specifically provided herein. Parent shall file with the
     Securities and Exchange Commission ("SEC"), no later than five (5) business
     days after Effective Time, a registration statement on Form S-8 relating to
     the shares of Parent Common Stock issuable with respect to the Company
     Options assumed by Parent in accordance with this Section 1.5(c). This
     Section 1.5(c) will survive the consummation of the Merger and the
     Effective Time, is intended to benefit and may be enforced by each of the
     persons who hold Company Options and/or Company Warrants and will be
     binding on all successors and assigns of Parent and the Surviving
     Corporation.
 
          (d) 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,
     then (unless such condition terminates by virtue of the Merger pursuant to
     the express terms 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.
 
     1.6  Closing of the Company's Transfer Books. At the Effective Time, (a)
all certificates representing 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 shareholders of the Company,
and (b) the stock transfer books of the Company shall be closed with respect to
all shares of such 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 of such
shares of Company Common Stock (a "Company Stock Certificate") is presented to
the Surviving Corporation or Parent, such Company Stock Certificate shall be
canceled and shall be exchanged as provided in Section 1.7.

<PAGE>   213
 
     1.7  Exchange of Certificates.
 
     (a) Exchange Procedures. At or as soon as practicable after the Closing,
the holders of Company Common Stock and Preferred Stock shall surrender their
Company Stock Certificates in exchange for certificates representing Parent
Common Stock or Parent Preferred Stock, as the case may be, pursuant to this
Agreement. Subject to Section 1.7(b), upon such surrender of a Company Stock
Certificate for exchange, (1) the holder of such Company Stock Certificate shall
be entitled to receive in exchange therefor a certificate representing the
number of shares of Parent Common Stock that such holder has the right to
receive pursuant to Section 1.5(a)(i), and (2) the Company Stock Certificate so
surrendered shall be canceled. Until surrendered as contemplated by this Section
1.7(a), 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 or Parent Preferred Stock, as the case may be (and cash in lieu of any
fractional share of Parent Common Stock or Parent Preferred Stock as
contemplated by Section 1.7(b)), pursuant to this Agreement. If any Company
Stock Certificate shall have been lost, stolen or destroyed, Parent shall issue
a certificate representing Parent Common Stock or Parent Preferred Stock, as the
case may be, with respect to such lost, stolen or destroyed Company Stock
Certificate in accordance with this Agreement upon delivery by the owner of such
lost, stolen or destroyed Company Stock Certificate to Parent of an appropriate
affidavit as indemnity against any claim that may be made against Parent or the
Surviving Corporation with respect to such Company Stock Certificate.
 
     (b) Fractional Shares. No fractional shares of Parent Common Stock or
Parent Preferred Stock shall be issued in connection with the Merger, and no
certificates for any such fractional shares shall be issued. In lieu of such
fractional shares, any holder of Company Common Stock or Company Preferred Stock
who would otherwise be entitled to receive a fraction of a share of Parent
Common Stock or Parent Preferred Stock (after aggregating all fractional shares
of Parent Common Stock and Parent Preferred Stock, respectively, issuable to
such holder) shall, upon surrender of such holder's Company Stock
Certificate(s), be paid in cash the dollar amount (rounded to the nearest whole
cent), without interest, determined by multiplying such fraction by the
Designated Parent Stock Price. The "Designated Parent Stock Price" shall be the
closing sales price of one share of Parent Common Stock as reported on the
Nasdaq National Market on the Closing Date.
 
     (c) No Liability. Neither Parent nor the Surviving Corporation shall be
liable to any holder or former holder of Company Common Stock for any shares of
Parent Common Stock or Parent Preferred Stock (or dividends or distributions
with respect thereto), or for any cash amounts, delivered to any public official
pursuant to any applicable abandoned property, escheat or similar law.
 
     1.8  Dissenting Shares. Notwithstanding anything to the contrary contained
in this Agreement, any shares of Company Common Stock or Company Preferred Stock
outstanding immediately prior to the Effective Time that were not voted in favor
of the Merger and are held by shareholders who have complied with the applicable
provisions of Chapter 13 of the CGCL (the "Dissenting Shares") shall not be
converted into or represent the right to receive Parent Common Stock or Parent
Preferred Stock in accordance with Sections 1.5(a)(i) and 1.5(a)(ii), as the
case may be (or cash in lieu of fractional shares in accordance with Section
1.7(b)), 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 CGCL. From and
after the Effective Time, a holder of Dissenting Shares shall not have and shall
not be entitled to exercise any of the voting rights or other rights of a
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
CGCL, 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 or Parent Preferred
Stock in accordance with Section 1.5(a)(i) (and cash in lieu of any fractional
share in accordance with Section 1.7(b)).
 
     1.9  Tax Consequences. For federal income tax purposes, the Merger is
intended to constitute a reorganization within the meaning of Section 368(a) 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.
 
                                        4
<PAGE>   214
 
     1.10  Accounting Treatment. For accounting purposes, the Merger is intended
to be treated as a purchase. For purposes of determining the purchase price, the
measurement date shall be December 18, 1997 based on the average of the closing
bid and ask prices per share of Parent's Common Stock as traded on the Nasdaq
Stock Market on such date (the "Applicable Price").
 
     1.11  Further Action. If, at any time after the Effective Time, any further
action is determined by Parent to be necessary to carry out the purposes of this
Agreement or to vest the Surviving Corporation or Parent 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.

distribute, sell, license or otherwise exploit each of the Parent Proprietary
Assets on an

exclusive basis. Part 3.9 of the Parent Disclosure Schedule lists all patents
held by and patent applications filed by Parent. Parent is the valid assignee or
record and owner of each of such patents and patent applications and all of such
patent applications are being actively prosecuted and none of such patents or
patent applications have been abandoned.
 
     (b) Parent and each Parent Subsidiary has taken reasonable measures and
precautions necessary to protect and maintain the confidentiality and secrecy of
all Parent Proprietary Assets (except Parent Proprietary Assets whose value
would be unimpaired by public disclosure) and otherwise to maintain and protect
the value of all Parent Proprietary Assets. Neither Parent nor any Parent
Subsidiary has disclosed or delivered or permitted to be disclosed or delivered
to any Person, and no Person (other than Parent or a Parent Subsidiary) has

either case except pursuant to a valid non-disclosure agreement.
 
     (c) To the knowledge of Parent, none of the Parent Proprietary Assets

nor any Parent Subsidiary has at any time infringed, misappropriated or made any
unlawful use of, or received any notice or other communication of any actual,
alleged, possible or potential infringement, misappropriation or unlawful use
of, any Proprietary Asset owned or used by any other Person. To the knowledge of

use of, and no Proprietary Asset owned or used by any other Person infringes or
conflicts with, any Parent Proprietary Asset.

necessary to enable Parent and each Parent Subsidiary to conduct its business in
the manner in which such business has been conducted. Neither Parent nor any
Parent Subsidiary has licensed any of the Parent Proprietary Assets to any
Person on an exclusive basis, and neither Parent nor any Parent Subsidiary has
entered into any covenant not to compete or Contract limiting its ability to
exploit fully any of its Proprietary Assets or to transact business in any
market or geographical area or with any Person.
 
     (e) No stockholder, officer or director of Parent has title to any Parent
Proprietary Asset which would be necessary to enable Parent to conduct its
business in the manner in which such business is currently being conducted.

     violation or breach of any of the provisions of any Parent Material
     Contract, (B) give any Person the right to declare a default or exercise
     any remedy under any Parent Material Contract, (C) give any Person the
     right to accelerate the maturity or performance of any Parent Material
     Contract, or (D) give any Person the right to cancel, terminate or modify

is, and has at all times been, in compliance with all applicable Legal
Requirements, except where the failure to comply with such Legal Requirements

all Governmental Authorizations necessary to enable Parent and such Parent
Subsidiary to conduct its business in the manner in which its business is
currently being conducted, except for Governmental Authorizations the failure of

each Parent Subsidiary is, and at all times has been, in compliance with the
material terms and requirements of such Governmental Authorizations, except for
any noncompliance which would not have a Material Adverse Effect on Parent.
Neither Parent nor any Parent Subsidiary has received any notice or other

respect to all periods through the dates thereof in accordance with generally
accepted accounting principles.
 
     (b) No claim or Legal Proceeding is pending or has been threatened against
or with respect to Parent or any Parent Subsidiary in respect of any Tax. There

expected to give rise to or serve as a basis for the commencement of any such
Legal Proceeding. There is no order, writ, injunction, judgment or decree to
which Parent or any Parent Subsidiary, or any of the assets owned or used by
Parent or any Parent Subsidiary, is subject. To the knowledge of Parent, no
officer or other employee of Parent or any Parent Subsidiary is subject to any
order, writ, injunction, judgment or decree that prohibits such officer or
 
                                       24

     Encumbrance upon or with respect to any asset owned or used by Parent or
     any Parent Subsidiary (except for minor liens that will not, in any case or
     in the aggregate, materially detract from the value of the assets subject
     thereto or would have a Material Adverse Effect on Parent).
 
     Except as may be required by the Securities Act, the Exchange Act, state
securities or "blue sky" laws, the CGCL, and the NASD Bylaws (as they relate to
the Joint Proxy Statement), neither Parent nor any Parent Subsidiary is nor will

comply with its fiduciary obligations to Parent's stockholders under applicable

     First: The name of the Corporation is Storage Dimensions, Inc.
 
     Second: The original Certificate of Incorporation of the Corporation was
filed with the Secretary of State of Delaware on November 25, 1992 under the
name SDI Acquisition Corporation.
 
     Third: The Board of Directors of the Corporation, acting in accordance with
the provisions of Sections 141 and 242 of the General Corporation Law of the
State of Delaware, adopted resolutions amending its Second Amended and Restated
Certificate of Incorporation as follows:
 
          ARTICLE I shall be amended and restated to read in its entirety as
     follows:
 
             "The name of the Corporation is Artecon, Inc. (hereinafter
        sometimes referred to as the "Corporation")."
 
          ARTICLE IV shall be amended and restated to read in its entirety as
     follows:
 
             "1. The Corporation is authorized to issue a total of Fifty Million
        (50,000,000) shares of stock in two classes designated respectively
        "Preferred Stock" and "Common Stock." The total number of shares of
        Preferred Stock the Corporation shall have authority to issue is Ten
        Million (10,000,000), par value one-half of one cent ($.005) per share,
        and the total number of shares of Common Stock the Corporation shall
        have authority to issue is Forty Million (40,000,000), par value
        one-half of one cent ($.005) per share.
 
             2. The preferences, privileges and restrictions granted to or
        imposed on the respective classes and series of shares of Common Stock
        and Preferred Stock are as follows:
 
                (a) Designation of Series of Preferred Stock. The Preferred
           Stock may be issued from time to time in one or more series. The
           Board of Directors is hereby authorized, within the limitations and
           restrictions stated in this Certificate of Incorporation, to fix or
           alter the dividend rights, dividend rate, conversion rights, voting
           rights, rights and terms of redemption (including sinking fund
           provisions), the redemption price or prices, and the liquidation
           preferences of any wholly unissued series of Preferred Stock, and the
           number of shares constituting any such series and the designation
           thereof, or any of them; and to increase or decrease the number of
           shares of any series subsequent to the issuance of shares of that
           series, but not below the number of shares of such series then
           outstanding. In case the number of shares of any series shall be so
           decreased, the shares constituting such decrease shall resume the
           status which they had prior to the adoption of the resolution
           originally fixing the number of shares of such series.
 
                (b) Designation of Series A Preferred Stock. Two Million Four
           Hundred Ninety-Four Thousand One Hundred Fifty-Nine (2,494,159) of
           the shares of Preferred Stock are hereby designated "Series A
           Preferred Stock" ("Series A Stock"). The rights, preferences and
           privileges of the Series A Stock are as specified in this Section 2
           of Article IV.
 
                (c) Dividend Rights. The holders of record of Preferred Stock
           and Common Stock shall be entitled to receive dividends on a
           non-cumulative basis when and as declared by the Board of Directors
           out of funds legally available therefor. No right shall accrue to the
           holders of the
 
                                       B-1
<PAGE>   257
 
           Series A Stock by reason of the fact that dividends are not declared
           and thereafter paid in any year.
 
                (d) Preference on Liquidation.
 
                    (i) In the event of any liquidation, dissolution or winding
               up of the Corporation, either voluntary or involuntary, the
               holders of the Series A Stock shall be entitled to receive, prior
               and in preference to any distribution of any of the assets or
               surplus funds of the Corporation to the holders of the Common
               Stock or any other class or series of stock of the Corporation,
               an amount equal to two dollars ($2.00) per share (as adjusted for
               any stock dividends, combinations or splits, reclassifications or
               the like with respect to such shares) plus all accrued,
               accumulated or declared but unpaid dividends on each share of
               Series A Stock held by such holders. If upon the occurrence of
               any liquidation, dissolution or winding up of the Corporation,
               either voluntary or involuntary, the assets and funds to be
               distributed among the holders of Series A Stock shall be
               insufficient to permit the payment to such holders of the full
               aforesaid preferential amount, the entire assets and funds of the
               Corporation legally available for distribution shall be
               distributed ratably among the holders of the Series A Stock in
               proportion to the preferential amount each such holder is
               otherwise entitled to receive.
 
                    (ii) After payment to the holders of the Series A Stock of
               the amount set forth in subsection (i), the entire remaining
               assets and funds of the Corporation legally available for
               distribution, if any, shall be distributed ratably among the
               holders of the Common Stock in proportion to the number of shares
               then held by such holders.
 
                    (iii) For purposes of this subsection (d), a merger or
               consolidation of the Corporation with or into any other
               corporation or corporations, or the merger of any other
               corporation or corporations into the Corporation in which the
               holders of the Corporation's outstanding Common Stock immediately
               prior to the effective date of such transaction do not hold at
               least fifty percent (50%) of all outstanding voting securities of
               the surviving entity, or a sale of all or substantially all of
               the assets of the Corporation, shall be treated as a liquidation,
               dissolution or winding up of the Corporation.
 
                (e) Voting Rights. Except as otherwise required by law, the
           shares of the Series A Stock shall be voted together with this
           Corporation's Common Stock as a single class at any annual or special
           meeting of stockholders of this Corporation, or may act by written
           consent in the same manner as this Corporation's Common Stock. Each
           share of Common Stock shall be entitled to one vote. The holder of
           each share of Series A Stock shall be entitled to the number of votes
           equal to the number of shares of Common Stock into which such share
           of Series A Stock could be converted on the record date for the vote
           or, if no such record date is established, at the date such vote is
           taken or any written consent is solicited (in each case assuming such
           share is convertible as of such date notwithstanding the time
           limitation on any such conversion set forth in Section 2(f)(i)),
           shall have voting rights and powers equal to the voting rights and
           powers of the Common Stock, and shall be entitled to notice of any
           stockholders meeting in accordance with the Bylaws of this
           Corporation in the same manner and to the same extent as holders of
           the Common Stock. Fractional votes shall not be permitted, however,
           and any fractional voting rights resulting from the above formula
           (after aggregating all shares into which shares of Series A Stock
           held by each holder could be converted) shall be rounded to the
           nearest whole number (with one-half being rounded upward.)
 
                (f) Conversion. The holders of the Series A Stock shall have the
           following rights and shall be subject to the following restrictions
           with respect to the conversion of the Series A Stock into shares of
           Common Stock:
 
                    (i) Conversion at the Option of the Holder. Each share of
               Series A Stock shall be convertible, at the option of the holder
               thereof, without the payment of additional
 
                                       B-2
<PAGE>   258
 
               consideration, at any time after January 1, 1999, at the office
               of the Corporation or any transfer agent for the Series A Stock,
               into such number of fully paid and nonassessable shares of Common
               Stock as is determined by dividing two dollars ($2.00) by the
               greater of (A) $6.00 and (B) the then applicable Conversion
               Price, determined as provided in subsection (f)(iii).
 
                    (ii) Automatic Conversion. Each share of Series A Stock
               shall automatically be converted into fully paid and
               nonassessable shares of Common Stock effective as of 5:30 p.m.
               East Coast Time on the earlier of:
 
                        (1) at the close of business on the day on which the
                   Board of Directors shall have duly and unanimously adopted a
                   resolution requesting such conversion, in which case the
                   number of shares of Common Stock issuable upon conversion of
                   each Share of Series A Stock shall be determined by dividing
                   two dollars ($2.00) by the then applicable Conversion Price,
                   determined as provided in subsection (f)(iii); and
 
                        (2) at the close of business on the first business day
                   following the date on which the average of the closing per
                   share sales price of the Common Stock as reported on the
                   Nasdaq National Market (or any other U.S. securities market
                   or exchange on which the Common Stock may trade) for twenty
                   (20) consecutive trading days equals or exceeds nine dollars
                   ($9.00) per share (subject to adjustment for any stock
                   splits, stock dividends, stock consolidations or the like)
                   (the "Average Price"), in which case the number of shares of
                   Common Stock issuable upon conversion of each such share of
                   Series A Stock shall be determined by dividing two dollars
                   ($2.00) by the Average Price.
 
                    (iii) Conversion Price. In the case of conversion under
               subsections (f)(i) and (f)(ii)(1), the conversion price for the
               Series A Stock shall be equal to the average of the closing sales
               prices of the Common Stock as traded on the Nasdaq National
               Market (or any other U.S. securities market or exchange on which
               the Common Stock may trade) during the twenty (20) trading day
               period ending on the day that is two (2) days prior to the date
               on which conversion is requested by the Company or the holder, as
               the case may be (the "Conversion Price"). Such Conversion Price
               shall be adjusted from time to time in accordance with this
               subsection (f). All references to the Conversion Price herein
               shall mean the Conversion Price as so adjusted.
 
                    (iv) Mechanics of Conversion. No fractional shares of Common
               Stock shall be issued upon conversion of Series A Stock. In lieu
               of any fractional shares to which the holder would otherwise be
               entitled, the Corporation shall pay cash equal to such fraction
               multiplied by the then effective Conversion Price. Before any
               holder of Series A Stock shall be entitled to convert the same
               into full shares of Common Stock pursuant to subsection (f)(i),
               it shall surrender the certificate or certificates therefor, duly
               endorsed, at the office of the Corporation or of any transfer
               agent for the Series A Stock, and shall give written notice to
               the Corporation at such office that it elects to convert the
               same. Such conversion shall be deemed to have been made
               immediately prior to the close of business on the date of such
               surrender of the shares of Series A Stock to be converted, and
               the person or persons entitled to receive the shares of Common
               Stock issuable upon such conversion shall be treated for all
               purposes as the record holder or holders of such shares of Common
               Stock on such date. In the event of a conversion pursuant to
               subsection (f)(ii), such conversion shall be deemed to have
               occurred automatically without any further action by the
               Corporation or the holder as of the day specified in subsection
               (f)(ii), and the person or persons entitled to receive the shares
               of Common Stock issuable upon such conversion shall be treated
               for all purposes as the record holder or holders of such shares
               of Common Stock on such date; provided, however, that before any
               holder of Series A Stock shall be entitled to receive a
               certificate representing the shares of Common Stock into
 
                                       B-3
<PAGE>   259
 
               which such holder's shares of Series A Stock have been converted
               into pursuant to subsection (f)(ii), it shall surrender the
               certificate or certificates representing such shares of Series A
               Stock, duly endorsed, at the office of the Corporation or of any
               transfer agent for the Series A Stock. The Corporation shall, as
               soon as practicable after receipt of such surrendered
               certificates and notice, if applicable, issue and deliver at such
               office to such holder of Series A Stock a certificate or
               certificates, registered in such names as specified by the
               holder, for the number of shares of Common Stock to which he
               shall be entitled as aforesaid and a check payable to the holder
               in the amount of any cash amounts payable as the result of a
               conversion into fractional shares of Common Stock.
 
                    (v) Adjustments to Conversion Price.
 
                        (1) In the event the Corporation shall at any time or
                   from time to time make or issue, or fix a record date for the
                   determination of holders of Common Stock entitled to receive,
                   a dividend or other distribution payable in securities of the
                   Corporation or any of its subsidiaries other than shares of
                   Common Stock, then in each such event provision shall be made
                   so that the holders of Series A Stock shall receive, upon the
                   conversion thereof, the securities of the Corporation which
                   they would have received had their stock been converted into
                   Common Stock on the date of such event.
 
                        (2) If there occurs any capital reorganization or any
                   reclassification of the capital stock of the Corporation
                   (other than any event provided for in subsection (f)(v)(1)
                   above), each share of Series A Stock shall thereafter be
                   convertible into the same kind and amounts of securities or
                   other assets, or both, that were issuable or distributable to
                   the holders of shares of outstanding Common Stock upon such
                   reorganization or reclassification, in respect of that number
                   of shares of Common Stock into which such shares of Series A
                   Stock might have been converted immediately prior to such
                   reorganization or reclassification; and in any such case,
                   appropriate adjustments (as determined by the Board of
                   Directors) shall be made in the application of the provisions
                   herein set forth with respect to the rights and interests
                   thereafter of the holders of Series A Stock to the end that
                   the provisions of this Article IV shall thereafter be
                   applicable, as nearly as reasonably may be, in relation to
                   any securities or other assets thereafter deliverable upon
                   the conversion of the Series A Stock.
 
                        (3) Upon the occurrence of each adjustment or
                   readjustment of the number or kind of shares issuable upon
                   conversion of a share of Series A Stock pursuant to this
                   subsection (f)(v), the Corporation at its expense shall
                   promptly compute such adjustment or readjustment in
                   accordance with the terms hereof and prepare and furnish to
                   each holder of Series A Stock a certificate setting forth
                   such adjustment or readjustment and showing in detail the
                   facts upon which such adjustment or readjustment is based.
                   The Corporation shall, upon the written request at any time
                   of any holder of Series A Stock, furnish or cause to be
                   furnished to such holder a like certificate prepared by the
                   Corporation setting forth (i) such adjustments and
                   readjustments, and (ii) the number of shares and the amount,
                   if any, of other property which at the time would be received
                   upon the conversion of Series A Stock.
 
                    (vi) Notices of Record Date. In the event of any taking by
               the Corporation of a record of the holders of any class of
               securities for the purpose of determining the holders thereof who
               are entitled to receive any dividend (other than a cash dividend)
               or other distribution, any security or right convertible into or
               entitling the holder thereof to receive additional shares of
               Common Stock, or any right to subscribe for, purchase or
               otherwise acquire any shares of stock of any class or any other
               securities or property, or to receive any other right, the
               Corporation shall mail to each holder of Series A Stock at least
               30 days prior to the date specified therein, a notice specifying
               the date on which any such record is
 
                                       B-4
<PAGE>   260
 
               to be taken for the purpose of such dividend, distribution,
               security or right, and the amount and character of such dividend,
               distribution, security or right.
 
                    (vii) Issue Taxes. The holders of Series A Stock shall pay
               any and all issue, transfer and other taxes that may be payable
               in respect of any issue or delivery of shares of Common Stock on
               conversion of shares of Series A Stock pursuant hereto.
 
                    (viii) Reservation of Stock Issuable Upon Conversion. The
               Corporation shall at all times reserve and keep available out of
               its authorized but unissued shares of Common Stock, solely for
               the purpose of effecting the conversion of the shares of the
               Series A Stock, such number of its shares of Common Stock as
               shall from time to time be sufficient to effect the conversion of
               all outstanding shares of the Series A Stock; and if at any time
               the number of authorized but unissued shares of Common Stock
               shall not be sufficient to effect the conversion of all then
               outstanding shares of the Series A Stock, the Corporation will
               take such corporate action as may, in the opinion of its counsel,
               be necessary to increase its authorized but unissued shares of
               Common Stock to such number of shares as shall be sufficient for
               such purpose, including, without limitation, engaging in best
               efforts to obtain the requisite stockholder approval of any
               necessary amendment to the Articles of Incorporation.
 
                    (ix) Notices. Any notice required by the provisions of this
               Section 2 to be given to the holders of shares of Series A Stock
               shall be deemed given if deposited in the United States mail,
               postage prepaid, and addressed to each holder of record at its
               address appearing on the books of the Corporation.
 
                (g) No Reissuance of Series A Stock. No share or shares of
           Series A Stock acquired by the Corporation by reason of conversion or
           otherwise shall be reissued. In the event of any such conversion or
           other acquisition, the shares so issued or acquired shall revert to
           the status of authorized but unissued shares of Preferred Stock."
 
          ARTICLE VII shall be amended and restated to read in its entirety as
     follows:
 
             "1. The number of directors which shall constitute the whole Board
        of Directors shall be fixed exclusively by one or more resolutions
        adopted by a majority of the total number of authorized directors
        (whether or not there exist any vacancies in previously authorized
        directorships at the time any such resolution is presented to the Board
        for adoption).
 
             2. Subject to the rights of the holders of any series of Preferred
        Stock (other than the Series A Stock) to elect additional directors
        under specified circumstances, the directors shall be divided into three
        classes as nearly equal in size as practicable designated as Class I,
        Class II and Class III, respectively. Directors shall be assigned to
        each class in accordance with a resolution or resolutions adopted by the
        Board of Directors. At the first annual meeting of stockholders
        following the adoption and filing of this Certificate of Amendment of
        Certificate of Incorporation, the term of office of the Class I
        directors shall expire and Class I directors shall be elected for a full
        term of three years. At the second annual meeting of stockholders
        following the adoption and filing of this Certificate of Amendment of
        Certificate of Incorporation, the term of office of the Class II
        directors shall expire and Class II directors shall be elected for a
        full term of three years. At the third annual meeting of stockholders
        following the adoption and filing of this Certificate of Amendment of
        Certificate of Incorporation (the "First Class Three Meeting"), the term
        of office of the Class III directors shall expire and Class III
        directors shall be elected for a full term of three years. At each
        succeeding annual meeting of stockholders, directors shall be elected
        for a full term of three years to succeed the directors of the class
        whose terms expire at such annual meeting.
 
             Notwithstanding the foregoing provisions of this Article, each
        director shall serve until his successor is duly elected and qualified
        or until his death, resignation or removal. No decrease in the number of
        directors constituting the Board of Directors shall shorten the term of
        any incumbent director.

             3. The Board of Directors or any individual director may be removed
        from office at any time (i) with cause by the affirmative vote of the
        holders of a majority of the voting power of all the then-outstanding
        shares of voting stock of the Corporation entitled to vote at an
        election of directors (the "Voting Stock") or (ii) without cause by (1)
        until the First Class III Meeting, the affirmative vote of the holders
        of at least eighty percent (80%) of the voting power of all the
        then-outstanding shares of the Voting Stock, and (2) after the First
        Class III Meeting, the affirmative vote of at least sixty-six and
        two-thirds percent (66 2/3%) of the voting power of all the
        then-outstanding shares of the Voting Stock."
 
     Fourth: Thereafter, pursuant to a resolution of the Board of Directors,
this Certificate of Amendment was submitted to the stockholders of the
Corporation for their approval, and was duly adopted in accordance with the
provisions of Section 242 of the General Corporation Law of the State of
Delaware.
 
     IN WITNESS WHEREOF, the undersigned,                          and
                         , have signed this Certificate of Amendment as
President and Secretary, respectively, of the Corporation, this     day of
          , 1998.

                      [LETTERHEAD OF SALOMON SMITH BARNEY]
 
December 22, 1997
 
The Board of Directors
Storage Dimensions, Inc.
1656 McCarthy Boulevard
Milpitas, California 93035
 
Members of the Board:
 
     You have requested our opinion as to the fairness, from a financial point
of view, to Storage Dimensions, Inc. ("Storage") of the consideration to be paid
by Storage pursuant to the terms and subject to the conditions set forth in the
Agreement and Plan of Merger and Reorganization, dated as of December 22, 1997
(the "Reorganization Agreement"), by and among Storage, Storage Acquisition
Corp., a wholly owned subsidiary of Storage ("Sub"), and Artecon, Inc.
("Artecon"). As more fully described in the Reorganization Agreement, (i) Sub
will be merged with and into Artecon (the "Merger"), (ii) each outstanding share
of the common stock of Artecon (the "Artecon Common Stock") will be converted
into that number of shares of the common stock, par value $0.005 per share, of
Storage (the "Storage Common Stock") equal to a fraction, the numerator of which
is that number of shares of Storage Common Stock equal to the product of (A)
1.5641 and (B) the sum of (x) the number of shares of Storage Common Stock
outstanding immediately prior to the effective time of the Merger (the
"Effective Time") plus (y) the maximum number of shares of Storage Common Stock
issuable upon exercise of options to purchase Storage Common Stock outstanding
as of the date of the Reorganization Agreement and that are also outstanding
immediately prior to the Effective Time with exercise prices less than $3.94
(the average of the closing bid and ask prices per share of Storage Common Stock
as traded on the Nasdaq Stock Market on December 18, 1997), and the denominator
of which is (A) the number of shares of Artecon Common Stock outstanding
immediately prior to the Effective Time plus (B) the number of shares of Artecon
Common Stock underlying instruments convertible into or exchangeable for Artecon
Common Stock outstanding immediately prior to the Effective Time, other than
2,494,159 shares of the preferred stock of Artecon (the "Artecon Preferred
Stock") held by the Sauey Affiliates (as defined in the Reorganization
Agreement) immediately prior to the closing of the Merger, and (iii) each
outstanding share of Artecon Preferred Stock will be converted into one share of
a new series of preferred stock of Storage (the "Storage Preferred Stock" and,
together with the Storage Common Stock into which shares of Artecon Common Stock
will be converted in the Merger, the "Merger Consideration").
 
     In arriving at our opinion, we reviewed the Reorganization Agreement and
held discussions with certain senior officers, directors and other
representatives and advisors of Storage and certain senior officers and other
representatives and advisors of Artecon concerning the businesses, operations
and prospects of Storage and Artecon. We examined certain publicly available
business and financial information relating to Storage and certain available
business and financial information relating to Artecon as well as certain
financial forecasts and other information and data for Storage and Artecon which
were provided to or otherwise discussed with us by the respective managements of
Storage and Artecon, including information relating to certain strategic
implications and operational benefits anticipated to result from the Merger. We
reviewed the financial terms of the Merger as set forth in the Reorganization
Agreement in relation to, among other things: current and historical market
prices and trading volumes of Storage Common Stock; the historical and projected
earnings and other operating data of Storage and Artecon; and the capitalization
and financial condition of Storage and Artecon. We considered, to the extent
publicly available, the financial terms of certain other similar transactions
recently effected which we considered relevant in evaluating the Merger and
analyzed certain financial, stock market and other publicly available
information relating to the businesses of other companies whose operations we
considered relevant in evaluating those of Storage and Artecon. We also
evaluated the potential pro forma financial impact of the Merger on Storage. In
addition to the foregoing, we conducted such other analyses and examinations and
considered such other financial, economic and market criteria as we deemed
appropriate in arriving at our opinion.

     In rendering our opinion, we have assumed and relied, without independent
verification, upon the accuracy and completeness of all financial and other
information and data publicly available or furnished to or otherwise reviewed by
or discussed with us. With respect to financial forecasts and other information
and data provided to or otherwise reviewed by or discussed with us, we have been
advised by the managements of Storage and Artecon that such forecasts and other
information and data were reasonably prepared on bases reflecting the best
currently available estimates and judgments of the respective managements of
Storage and Artecon as to the future financial performance of Storage and
Artecon and the strategic implications and operational benefits (including the
amount, timing and achievability thereof) anticipated to result from the Merger.
We have assumed, with your consent, that the Merger will be treated as a
tax-free reorganization for federal income tax purposes. We also have assumed,
with your consent, that the number of fully diluted shares of Storage Common
Stock outstanding immediately prior to the Effective Time will not vary
materially from the number of fully diluted shares of Storage Common Stock
outstanding as of the date hereof. Our opinion, as set forth herein, relates to
the relative values of Storage and Artecon. We are not expressing any opinion as
to what the value of the Storage Common Stock or Storage Preferred Stock
actually will be when issued pursuant to the Merger, what the value of the
Storage Common Stock will be upon conversion of the Storage Preferred Stock or
the prices at which the Storage Common Stock or Storage Preferred Stock will
trade or otherwise be transferable subsequent to the Merger. We have not made or
been provided with an independent evaluation or appraisal of the assets or
liabilities (contingent or otherwise) of Storage or Artecon nor have we made any
physical inspection of the properties or assets of Storage or Artecon. We were
not requested to consider, and our opinion does not address, the relative merits
of the Merger as compared to any alternative business strategies that might
exist for Storage or the effect of any other transaction in which Storage might
engage. Our opinion is necessarily based upon information available to us, and
financial, stock market and other conditions and circumstances existing and
disclosed to us, as of the date hereof.
 
     Smith Barney Inc. (now associated with Salomon Brothers Inc and
collectively with Salomon Brothers Inc doing business as Salomon Smith Barney)
has been engaged to render financial advisory services to Storage in connection
with the Merger and will receive a fee for such services, a significant portion
of which is contingent upon consummation of the Merger. We also will receive a
fee upon the delivery of this opinion. We have in the past provided investment
banking services to Storage unrelated to the proposed Merger, for which services
we have received compensation. In the ordinary course of our business, we and
our affiliates may actively trade or hold the securities of Storage for our own
account or for the account of our customers and, accordingly, may at any time
hold a long or short position in such securities. In addition, we and our
affiliates (including Travelers Group Inc. and its affiliates) may maintain
relationships with Storage and Artecon.
 
     Our advisory services and the opinion expressed herein are provided for the
information of the Board of Directors of Storage in its evaluation of the
proposed Merger, and our opinion is not intended to be and does not constitute a
recommendation to any stockholder as to how such stockholder should vote on any
matter relating to the proposed Merger. Our opinion may not be published or
otherwise used or referred to, nor shall any public reference to Salomon Smith
Barney be made, without our prior written consent.
 
     Based upon and subject to the foregoing, our experience as investment
bankers, our work as described above and other factors we deemed relevant, we
are of the opinion that, as of the date hereof, the Merger Consideration is
fair, from a financial point of view, to Storage.
Very truly yours,
 
SALOMON SMITH BARNEY

                       CALIFORNIA GENERAL CORPORATION LAW
 
                         CHAPTER 13. DISSENTERS' RIGHTS
 
     1300. SHORT FORM MERGER; PURCHASE OF SHARES AT FAIR MARKET VALUE;
"DISSENTING SHARES" AND DISSENTING SHAREHOLDER. -- (a) If the approval of the
outstanding shares (Section 152) of a corporation is required for a
reorganization under subdivisions (a) and (b) or subdivision (e) or (f) of
Section 1201, each shareholder of the corporation entitled to vote on the
transaction and each shareholder of a subsidiary corporation in a short-form
merger may, by complying with this chapter, require the corporation in which the
shareholder holds shares to purchase for cash at their fair market value the
shares owned by the shareholder which are dissenting shares as defined in
subdivision (b). The fair market value shall be determined as of the day before
the first announcement of the terms of the proposed reorganization or short-form
merger, excluding any appreciation or depreciation in consequence of the
proposed action, but adjusted for any stock split, reverse stock split, or share
dividend which becomes effective thereafter.
 
     (b) As used in this chapter, "dissenting shares" means shares which come
within all of the following descriptions:
 
          (1) Which were not immediately prior to the reorganization or
     short-form merger either (A) listed on any national securities exchange
     certified by the Commissioner of Corporations under subdivision (o) of
     Section 25100 or (B) listed on the list of OTC margin stocks issued by the
     Board of Governors of the Federal Reserve System, and the notice of meeting
     of shareholders to act upon the reorganization summarizes this section and
     Sections 1301, 1302, 1303 and 1304; provided, however, that this provision
     does not apply to any shares with respect to which there exists any
     restriction on transfer imposed by the corporation or by any law or
     regulation; and provided, further, that this provision does not apply to
     any class of shares described in 3 subparagraph (A) or (B) if demands for
     payment are filed with respect to 5 percent or more of the outstanding
     shares of that class.
 
          (2) Which were outstanding on the date for the determination of
     shareholders entitled to vote on the reorganization and (A) were not voted
     in favor of the reorganization or, (B) if described in subparagraph (A) or
     (B) or paragraph (1) (without regard to the provisos in that paragraph),
     were voted against the reorganization, or which were held of record on the
     effective date of a short-form merger; provided, however, that subparagraph
     (A) rather than subparagraph (B) of this paragraph applies in any case were
     the approval required by Section 1201 is sought by written consent rather
     than at a meeting.
 
          (3) Which the dissenting shareholder has demanded that the corporation
     purchase at their fair market value, in accordance with Section 1301.
 
          (4) Which the dissenting shareholder has submitted for endorsement, in
     accordance with Section 1302.
 
     (c) As used in this chapter, "dissenting shareholder" means the
recordholder of dissenting shares and includes a transferee of record.
 
     1301. DISSENTER'S RIGHTS; DEMAND ON CORPORATION FOR PURCHASE OF
SHARES. -- (a) If, in the case of a reorganization, any shareholders of a
corporation have a right under Section 1300, subject to compliance with
paragraphs (3) and (4) of subdivisions (b) thereof, to require the corporation
to purchase their shares for cash, such corporation shall mail to each such
shareholder a notice of the approval of the reorganization by its outstanding
shares (Section 152) within 10 days after the date of such approval, accompanied
by a copy of Sections 1300, 1302, 1303, 1304 and this section, a statement of
the price determined by the corporation to represent the fair market value of
the dissenting shares, and a brief description of the procedure to be followed
if the shareholder desires to exercise the shareholder's right under such
sections. The statement of price constitutes an offer by the corporation to
purchase at the price stated any dissenting shares as defined in subdivisions
(b) of Section 1300, unless they lose their status as dissenting shares under
Section 1309.
 
                                       D-1
<PAGE>   265
 
     (b) Any shareholder who has a right to require the corporation to purchase
the shareholder's shares for cash under Section 1300, subject to compliance with
paragraphs (3) and (4) of subdivision (b) thereof, and who desires the
corporation to purchase such shares shall make written demand upon the
corporation for the purchase of such shares and payment to the shareholder in
cash of their fair market value. The demand is not effective for any purpose
unless it is received by the corporation or any transfer agent thereof (1) in
the case of shares describe in clause (i) or (ii) of paragraph (1) of
subdivision (b) of Section 1300 (without regard to the provisos in that
paragraph), not later than the date of the shareholders' meeting to vote upon
the reorganization, or (2) in any other case within 30 days after the date on
which the notice of the approval by the outstanding shares pursuant to
subdivision (a) or the notice pursuant to subdivision (i) of Section 1110 was
mailed to the shareholder.
 
     (c) The demand shall state the number and class of the shares held of
record by the shareholder which the shareholder demands that the corporation
purchase and shall contain a statement of what such shareholder claims to be the
fair market value of those shares as of the day before the announcement of the
proposed reorganization or shortform merger. The statement of fair market value
constitutes an offer by the shareholder to sell the shares at such price.
 
     1302. DISSENTING SHARES, STAMPING OR ENDORSING. -- Within 30 days after the
date on which notice of the approval by the outstanding shares or the notice
pursuant to subdivision (i) of Section 1110 was mailed to the shareholder, the
shareholder shall submit to the corporation at its principal office or at the
office of any transfer agent thereof, (a) if the shares are certificated
securities, the shareholder's certificates representing any shares which the
shareholder demands that the corporation purchase, to be stamped or endorsed
with a statement that the shares are dissenting shares or to be exchanged for
certificates of appropriate denomination so stamped or endorsed or (b) if the
shares are uncertificated securities, written notice of the number of shares
which the shareholder demands that the corporation purchase. Upon subsequent
transfers of the dissenting shares on the books of the corporation the new
certificates, initial transaction statement, and other written statements issued
therefor shall bear a like statement, together with the name of the original
dissenting holder of the shares.
 
     1303. DISSENTING SHAREHOLDER ENTITLED TO AGREED PRICE WITH INTEREST; TIME
OF PAYMENT. -- (a) If the corporation and the shareholder agree that the shares
are dissenting shares and agree upon the price of the shares, the dissenting
shareholder is entitled to the agreed price with interest thereon at the legal
rate on judgments from the date of the agreement. Any agreements fixing the fair
market value of any dissenting shares as between the corporation and the holders
thereof shall be filed with the secretary of the corporation.
 
     (b) Subject to the provisions of Section 1306, payment of the fair market
value of dissenting shares shall be made within 30 days after the amount thereof
has been agreed or within 30 days after any statutory or contractual conditions
to reorganization are satisfied, whichever is later, and in the case of
certificated securities, subject to surrender of the certificates therefor,
unless provided otherwise by agreement.
 
     1304. DISSENTERS ACTIONS; JOINDER; CONSOLIDATION; APPOINTMENT OF
APPRAISERS. -- (a) If the corporation denies that the shares are dissenting
shares, or the corporation and the shareholder fail to agree upon the fair
market values of the shares, then the shareholder demanding purchase of such
shares as dissenting shares or any interested corporation, within six months
after the date on which notice of the approval by the outstanding shares
(Section 152) or notice pursuant to subdivision (i) of Section 1110 was mailed
to the shareholder, but not thereafter, may file a complaint in the superior
court of the proper county praying the court to determine whether the shares are
dissenting shares or the fair market value of the dissenting shares or both or
may intervene in any action pending on such a complaint.
 
     (b) Two or more dissenting shareholders may join as plaintiffs or be joined
as defendants in any such action and two or more such actions may be
consolidated.
 
     (c) On the trial of the action, the court shall determine the issues. If
the status of the shares as dissenting shares is in issue, the court shall first
determine that issue. If the fair market value of the dissenting shares is in
issue, the court shall determine, or shall appoint one or more impartial
appraisers to determine, the fair market value of the shares.
 
     1305. APPRAISERS DUTY AND REPORT; COURT JUDGMENT; PAYMENT; APPEAL; COSTS OF
ACTION. -- (a) If the court appoints an appraiser or appraisers, they shall
proceed forthwith to determine the fair market value per
                                       D-2
<PAGE>   266
 
share. Within the time fixed by the court, the appraisers, or a majority of
them, shall make and file a report in the office of the clerk of the court.
Thereupon, on the motion of any party, the report shall be submitted to the
court and considered on such evidence as the court considers relevant. If the
court finds the report reasonable, the court may confirm it.
 
     (b) If a majority of the appraisers appointed fail to make and file a
report within 10 days from the date of their appointment or within such further
time as may be allowed by the court or the report is not confirmed by the court,
the court shall determine the fair market vale of the dissenting shares.
 
     (c) Subject to the provisions of Section 1306, judgment shall be rendered
against the corporation for payment of an amount equal to the fair market value
of each dissenting share multiplied by the number of dissenting shares which any
dissenting shareholder who is a party, or who has intervened, is entitled to
require the corporation to purchase, with interest thereon at the legal rate
from the date on which judgment was entered.
 
     (d) Any such judgment shall be payable forthwith with respect to
undercertificated securities and, with respect to certificated securities, only
upon the endorsement and delivery to the corporation of the certificates for the
shares described in the judgment. Any party may appeal from the judgment.
 
     (e) The costs of the action, including reasonable compensation to the
appraisers to be fixed by the court, shall be assessed or apportioned as the
court considers equitable, but, if the appraisal exceeds the price offered by
the corporation, the corporation shall pay the costs (including in the
discretion of the court attorneys' fees, fees of expert witnesses and interest
at the legal rate on judgments from the date of compliance with Section 1300,
1301 and 1302 if the value awarded by the court for the shares is more than 125
percent of the price offered by the corporation under subdivision (a) of Section
1301).
 
     1306. DISSENTING SHAREHOLDERS; EFFECT OF PREVENTION OF PAYMENT OF
FAIRMARKET VALUE. -- To the extent that the provisions of Chapter 5 prevent the
payment to any holders of dissenting shares of their fair market value, they
shall become creditors of the corporation for the amount thereof together with
interest at the legal rate on judgments until the date of payment, but
subordinate to all other creditors in any liquidation proceeding, such debt to
be payable when permissible under the provisions of Chapter 5.
 
     1307. DISSENTING SHARES, DISPOSITION OF DIVIDENDS. -- Cash dividends
declared and paid by the corporation upon the dissenting shares after the date
of approval of the reorganization by the outstanding shares (Section 152) and
prior to payment for the shares by the corporation shall be credited against the
total amount to be paid by the corporation therefor.
 
     1308. DISSENTING SHARES, RIGHTS AND PRIVILEGES. -- Except as expressly
limited in this chapter, holders of dissenting shares continue to have all the
rights and privileges incident to their shares, until the fair market value of
their shares is agreed upon or determined. A dissenting shareholder may not
withdraw a demand for payment unless the corporation consents thereto.
 
     1309. DISSENTING SHARES, LOSS OF STATUS. -- Dissenting shares lose their
status as dissenting shares and the holders thereof cease to be dissenting
shareholders and cease to be entitled to require the corporation to purchase
their shares upon the happening of any of the following:
 
     (a) The corporation abandons the reorganization. Upon abandonment of the
reorganization, the corporation shall pay on demand to any dissenting
shareholder who has initiated proceedings in good faith under this chapter all
necessary expenses incurred in such proceedings and reasonable attorneys' fees.
 
     (b) The shares are transferred prior to their submission for endorsement in
accordance with Section 1302 or are surrendered for conversion into shares of
another class in accordance with the articles.
 
     (c) The dissenting shareholder and the corporation do not agree upon the
status of the shares as dissenting shares or upon the purchase price of the
shares, and neither files a complaint or intervenes in a pending action as
provided in Section 1304, within six months after the date on which notice of
the approval by the outstanding shares or notice pursuant to subdivisions (i) of
Section 1110 was mailed to the shareholder.
 
     (d) The dissenting shareholder, with the consent of the corporation,
withdraws the shareholder's demand for purchase of the dissenting shares.
 
                                       D-3
<PAGE>   267
 
     1310. SUSPENSION OF CERTAIN PROCEEDINGS WHILE LITIGATION IS PENDING. -- If
litigation is instituted to test the sufficiency of regularity of the votes of
the shareholder in authorizing a reorganization, any proceedings under Section
1304 and 1305 shall be suspended until final determination of such litigation.
 
     1311. CHAPTER INAPPLICABLE TO CERTAIN CLASSES OF SHARES. -- This chapter,
except Section 1312, does not apply to classes of shares whose terms and
provisions specifically set forth the amount to be paid in respect to such
shares in the event of a reorganization or merger.
 
     1312. VALIDITY OF REORGANIZATION OR SHORT FORM MERGER, ATTACK ON;
SHAREHOLDERS' RIGHTS; BURDEN OF PROOF. -- (a) No shareholder of a corporation
who has a right under this chapter to demand payment of cash for the shares held
by the shareholder shall have any right or law or in equity to attack the
validity of the reorganization or short-form merger, or to have the
reorganization or short-form merger set aside or rescinded, except in an action
to test whether the number of shares required to authorize or approve the
reorganization have been legally voted in favor thereof; but any holder of
shares of a class whose terms and provisions specifically set forth the amount
to be paid in respect to them in the event of a reorganization or short-form
merger is entitled to payment in accordance with those terms and provisions or,
if the principal terms of the reorganization are approved pursuant to
subdivision(b) of Section 1202, is entitled to payment in accordance with the
terms and provisions of the approved reorganization.
 
     (b) If one of the parties to a reorganization or short-form merger is
directly or indirectly controlled by, or under common control with, another
party to the reorganization or short-form merger, subdivision (a) shall not
apply to any shareholder of such party who has not demanded payment of cash for
such shareholder's shares pursuant to this chapter; but if the shareholder

directly or indirectly controlled by, or under common control with, another
party to the reorganization or short-form merger, in any action to attack the

reorganization or short-form merger set aside or rescinded, (1) a party to a
reorganization or short-form merger which controls another party to the
reorganization or short-form merger shall have the burden of proving that the
transaction is just and reasonable as to the shareholders of the controlled
party, and (2) a person who controls two or more parties to a reorganization
shall have the burden of proving that the transaction is just and reasonable as
to the shareholders of any party so controlled.

                           FORM OF IRREVOCABLE PROXY
 
                               IRREVOCABLE PROXY
 
     The undersigned stockholder of Storage Dimensions, Inc., a Delaware
corporation ("Parent"), hereby irrevocably (to the fullest extent permitted by
law) appoints and constitutes James L. Lambert, Tesfaye Hailemichael and
Artecon, Inc, Inc., a California corporation ("Company"), and each of them, the
attorneys and proxies of the undersigned with respect to (i) the shares of
capital stock of Parent owned by the undersigned as of the date of this proxy,
which shares are specified on the final page of this proxy and (ii) any and all
other shares of capital stock of Parent which the undersigned may acquire after
the date hereof. (The shares of the capital stock of Parent referred to in
clauses (i) and (ii) of the immediately preceding sentence are collectively
referred to as the "Shares.") Upon the execution hereof, all prior proxies given
by the undersigned with respect to any of the Shares are hereby revoked, and no
subsequent proxies will be given with respect to any of the Shares.
 
     This proxy is irrevocable, is coupled with an interest and is granted in
connection with the Voting Agreement, dated as of the date hereof, between
Company and the undersigned (the "Voting Agreement"), and is granted in
consideration of Company entering into the Agreement and Plan of Merger and
Reorganization, dated as of the date hereof, among Parent, Storage Acquisition
Corp., a California corporation and wholly owned subsidiary of Parent, and the
Company (the "Reorganization Agreement"). Capitalized terms used but not
otherwise defined in this proxy have the meanings ascribed to such terms in the
Reorganization Agreement.
 
     The attorney and proxy named above will be empowered, and may exercise this
proxy, to vote the Shares at any time until the earlier to occur of the valid
termination of the Reorganization Agreement or the Effective Time at any meeting
of the stockholders of Parent, however called, or in any written action by
consent of stockholders of Parent:
 
          1. in favor of the issuance of the Merger Shares, the Merger, the
     execution and delivery by the Parent of the Reorganization Agreement and
     the adoption and approval of the terms thereof and in favor of each of the
     other actions contemplated by the Reorganization Agreement and any action
     required in furtherance hereof and thereof;
 
          2. against any action or agreement that would result in a breach of
     any representation, warranty, covenant or obligation of Parent in the
     Reorganization Agreement; and
 
          3. against the following actions (other than the Merger and the
     transactions contemplated by the Reorganization Agreement): (A) any
     extraordinary corporate transaction, such as a merger, consolidation or
     other business combination involving the Parent or any subsidiary of the
     Parent; (B) any sale, lease or transfer of a material amount of assets of
     the Parent or any subsidiary of the Parent (other than in the ordinary
     course of business); (C) any reorganization, recapitalization, dissolution
     or liquidation of the Parent or any subsidiary of the Parent; (D) any
     change in a majority of the board of directors of the Parent; (E) any
     amendment to the Parent's articles of incorporation; (F) any material
     change in the capitalization of the Parent or the Parent's corporate
     structure; or (G) any other action which is intended, or could reasonably
     be expected to, impede, interfere with, delay, postpone, discourage or
     adversely affect the Merger or any of the other transactions contemplated
     by the Reorganization Agreement or this Voting Agreement.
 
     The undersigned stockholder may vote the Shares on all other matters.
 
     Any obligation of the undersigned hereunder shall be binding upon the
heirs, successors and assigns of the undersigned (including any transferee of
any of the Shares).

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS
 
     As permitted by Section 145 of the Delaware General Corporation Law, the
Registrant's Amended and Restated Certificate of Incorporation includes a
provision that eliminates the personal liability of its directors for monetary
damages for breach or alleged breach of their duty of care. In addition, as
permitted by Section 145 of the Delaware General Corporation Law, the Bylaws, as
amended, of the Registrant provide that: (i) the Registrant is required to
indemnify its directors and officers and persons serving in such capacities in
other business enterprises (including, for example, subsidiaries of the
Registrant) at the Registrant's request, to the fullest extent permitted by
Delaware law, including in those circumstances in which indemnification would
otherwise be discretionary; (ii) the Registrant may, in its discretion,
indemnify employees and agents in those circumstances where indemnification is
not required by law; (iii) the Registrant is required to advance expenses, as
incurred, to its directors and officers in connection with defending a
proceeding (except that it is not required to advance expenses to a person
against whom the Registrant brings a claim for breach of the duty of loyalty,
failure to act in good faith, intentional misconduct, knowing violation of law
or deriving an improper personal benefit); (iv) the rights conferred in the
Bylaws, as amended, are not exclusive, and the Registrant is authorized to enter
into indemnification agreements with its directors, officers and employees; and
(v) the Registrant may not retroactively amend the Bylaw provisions in a way
that is adverse to such directors, officers and employees.
 
     The Registrant has entered into indemnification agreements with each of its
directors and officers that provide the maximum indemnity allowed to directors
and officers by Section 145 of the Delaware General Corporation Law and the
Bylaws, as amended, as well as certain additional procedural protections.
 
     The indemnification provisions in the Bylaws, as amended, and the
indemnification agreements entered into between the Registrant and its directors
and officers may be sufficiently broad to permit indemnification of the
Registrant's directors and officers for liabilities arising under the Securities
Act.

     (c) ITEM 4(B) REPORTS
 
     Reference is made to Annex C to the Joint Proxy Statement/Prospectus which
is included in this Registration Statement.
 
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 this Form, 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: (a) to file, during any period in
which offers or sales are being made, a post-effective amendment to this
Registration Statement, (i) to include any prospectus required by Section
10(a)(3) of the Securities Act, (ii) to reflect in the prospectus any facts or
events arising after the effective date of the Registration Statement (or the
most recent post-effective amendment thereof) which, individually or in the
aggregate, represent a fundamental change in the information set forth in the
Registration Statement. Notwithstanding the foregoing, any increase or decrease
in volume of securities offered (if the total dollar value of securities offered
would not exceed that which was registered) and any deviation from the low or
high end of the estimated maximum offering range may be reflected in the form of
prospectus filed with the Commission pursuant to Rule 424(b)(sec.230.424(b) of
this chapter) if, in the aggregate, the changes in volume and price represent no
more than a 20% change in the maximum aggregate offering price set forth in the
"Calculation of Registration Fee" table in the effective registration statement,
and (iii) to include any material information with respect to the plan of
distribution not previously disclosed in the registration statement or any
material change to such information in the Registration Statement; (b) that, for
the purpose 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; and
(c) to remove from registration by means of a post-effective amendment any of
the securities being registered which remain unsold at the termination of the
offering.
 
     (3) 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 Delaware Corporation Law, the Registrant's Amended
and Restated Certificate of Incorporation, the Registrant's Bylaws, as amended,
the Registrant's indemnification agreements or otherwise, the Registrant has
been advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Securities Act, and
is, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by the Registrant of expenses
incurred or paid by a director, officer or controlling person of the Registrant
in the successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered hereunder, the Registrant will, unless in the opinion of its counsel
the matter has been settled by controlling precedent, submit to a court of
appropriate jurisdiction the question whether such indemnification by it is
against public policy as expressed in the Securities Act and will be governed by
the final adjudication of such issue.
 
     (4)(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.

<PAGE>   288
 
     (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 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 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.

        Re:    Storage Dimensions, Inc. Registration Statement on Form S-4

Ladies and Gentlemen:

        We have examined the Registration Statement on Form S-4 to be filed by
you with the Securities and Exchange Commission on, or about March 9, 1998, (the
"Registration Statement") in connection with the registration under the
Securities Act of 1933, as amended, of 13,982,776 shares of your Common Stock,
par value $.005 per share and of 2,494,159 shares of your Preferred Stock, par
value $.005 per share (collectively the "Shares"). The Shares are to be issued
in connection with the merger of Storage Acquisition Corp., a California
corporation and a wholly-owned subsidiary of Storage Dimensions, Inc., with and
into Artecon, Inc., a California corporation, pursuant to an Agreement of Merger
and Plan of Reorganization dated as of December 22, 1997 (the "Merger
Agreement"). As your counsel in connection with this transaction, we have
examined the proceedings taken and proposed to be taken in connection with the
issuance of the Shares.

        It is our opinion that, upon completion of the proceedings being taken
or contemplated to be taken prior to the issuance of the Shares, the Shares,
when issued in the manner referred to in the Merger Agreement will be legally
and validly issued, fully paid and nonassessable.

        We consent to the use of this opinion as an exhibit to the Registration
Statement, and further consent to the use of our name wherever appearing in the
Registration Statement, including the Prospectus/Proxy Statement constituting a
part thereof, and any amendment thereto.

                                    Very truly yours,

                                    WILSON SONSINI GOODRICH & ROSATI
                                    Professional Corporation

                                March 9, 1998


Storage Dimensions, Inc.
1656 McCarthy Boulevard
Milpitas, California  95035

Ladies and Gentlemen:

        We have acted as counsel for Storage Dimensions, Inc., a Delaware
corporation ("Storage") in connection with the preparation and execution of the
Agreement and Plan of Merger and Reorganization dated as of December 22, 1997
(the "Reorganization Agreement") among Storage, Storage Acquisition Corp., a
wholly-owned subsidiary of Storage incorporated in California ("Merger Sub"),
and Artecon, Inc., a California corporation ("Artecon"). Pursuant to the
Reorganization Agreement, Merger Sub will merge with and into Artecon (the
"Merger"), and Artecon will become a wholly-owned subsidiary of Storage. Unless
otherwise defined, capitalized terms referred to herein 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").

        You have requested our opinion regarding certain United States federal
income tax consequences of the Merger. In delivering this opinion, we have
reviewed and relied upon the facts, statements, descriptions and representations
set forth in the Reorganization Agreement (including Exhibits) and the Form S-4
Registration Statement (the "Registration Statement") filed with the Securities
and Exchange Commission, and such other documents pertaining to the Merger as we
have deemed necessary or appropriate. We have also relied upon certificates of
officers of Storage and Artecon respectively (the "Officers' Certificates") and
Continuity of Interest Certificates executed by certain shareholders of Artecon.

        In connection with rendering this opinion, we have also assumed (without
any independent investigation) that:

        1. Original documents (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;

        2. Any statement made in any of the documents referred to herein,"to the
best of the knowledge" of any person or party is correct without such
qualification;


<PAGE>   2


Storage Dimensions, Inc.
March 9, 1998
Page 2


        3. All statements, descriptions and representations contained in any of
the documents referred to herein or otherwise made to us are true and correct in
all material respects and no actions have been (or will be) taken which are
inconsistent with such representations;

        4. The Merger will be reported by Storage and Artecon on their
respective federal income tax returns in a manner consistent with the opinion
set forth below;

        5. The Merger will be consummated pursuant to the Reorganization
Agreement and will be effective under the laws of the States of Delaware and
California; and

        6. The shareholders of Artecon do not, and will not on or before the
Effective Time, have an existing plan or intent to dispose of an amount of
Storage common stock and Storage preferred stock to be received in the Merger
(or to dispose of Artecon capital stock in anticipation of the Merger) such that
the shareholders of Artecon will not receive and retain a meaningful continuing
equity ownership in Storage that is sufficient to satisfy the continuity of
interest requirement as specified in Treas. Reg. Section 1.368-1(b) and as
interpreted in certain Internal Revenue Service rulings and federal judicial
decisions.

        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, if the Merger is consummated in accordance with the
Reorganization Agreement (and without any waiver, breach or amendment of any of
the provisions thereof) and the statements set forth in the Officers'
Certificates and the Continuity of Interest Certificates are true and correct as
of the Effective Time, then it is our opinion that:

        (i)    For federal income tax purposes, the Merger will qualify as a
               "reorganization" as defined in Section 368(a) of the Code; and

        (ii)   The discussion entitled "Certain Federal Income Tax Matters" in
               the Prospectus constituting a part of the Registration Statement,
               insofar as it relates to statements of law and legal conclusions,
               is correct in all material respects.

        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, would 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.

        This opinion addresses only the matters described above and does not
address any other federal, state, local or foreign tax consequences that may
result from the Merger or any other transaction (including any transaction
undertaken in connection with the Merger).

        No opinion is expressed as to any transaction other than the Merger as
described in the Reorganization Agreement or to any transaction whatsoever,
including the Merger, if all the transactions described in the Reorganization
Agreement are not consummated in accordance with the terms of such
Reorganization 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 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 has been delivered to you solely in connection with the
Registration Statement. It may not be relied upon for any other purpose or by
any other person or entity, and may not be made available to any other person or
entity without our prior written consent. We hereby consent to the reference to
our firm under the caption "Certain Federal Income Tax Matters" in the Proxy
Statement included in the Registration Statement and to the filing of this
opinion as an exhibit to the Registration Statement.

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 December 22, 1997
(the "Reorganization Agreement") by and among Storage Dimensions, Inc., a
Delaware corporation ("Parent"), Storage Acquisition Corp., a California
corporation and wholly owned subsidiary of Parent ("Merger Sub"), and Artecon,
Inc., a California corporation (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 the Company 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) those certain tax representation letters dated March 9, 1998,
delivered to us by Parent, Merger Sub and the Company containing certain
representations of Parent, Merger Sub and the Company (the "Tax Representation
Letters");

        (c) Continuity of Interest Certificates delivered to us by certain

In connection with rendering this opinion, we have assumed (without any
independent investigation or review thereof) that:

        1. 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 will be by the Effective
Time) duly and validly executed and delivered where due execution and delivery
are a prerequisite to the effectiveness thereof;

        2. All representations, warranties and statements made or agreed to by
Parent, Merger Sub and the Company, their managements, employees, officers,
directors and shareholders in connection with the Merger, including, but not
limited to, those set forth in the Reorganization Agreement (including the
exhibits thereto), the Tax Representation Letters and the Continuity of Interest
Certificates are true and accurate at all relevant times;

        3. All covenants contained in the Reorganization Agreement (including
exhibits thereto), the Tax Representation Letters and the Continuity of Interest
Certificates are performed without waiver or breach of any material provision
thereof;

        4. 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;

        5. There is no plan or intention on the part of the shareholders of the
Company to engage in a sale, exchange, transfer, distribution, pledge, or other
disposition or any transaction which results in a reduction of risk of
ownership, or a direct or indirect disposition of shares of Parent Common Stock
and Parent Preferred Stock (collectively, "Parent Stock") to be received in the
Merger that would reduce the Company's shareholders' ownership of Parent Stock
to a number of shares having an aggregate fair market value, as of the Effective
Time, of less than fifty percent (50%) of the aggregate fair market value of all
of the Company capital stock outstanding immediately prior to the Effective
Time. (For purposes of the preceding sentence, shares of Company capital stock
pursuant to which shareholders of the Company exercise dissenters' rights in the
Merger, which are exchanged for consideration in the Merger other than shares of
Parent Stock, including being exchanged for cash in lieu of fractional shares of
Parent Stock or are sold, redeemed or disposed of in a transaction that is in
contemplation of or related to the Merger, shall be considered shares of the
Company capital stock held by shareholders of the Company immediately prior to
the Merger which are exchanged for shares of Parent Stock in the Merger and then
disposed of pursuant to a plan); and

        6. Any representation or statement made "to the best of knowledge" or
similarly qualified is correct without such qualification.

Based on our examination of the foregoing items and subject to the limitations,
qualifications, assumptions and caveats set forth herein, we are of the opinion
that, for federal income tax

purposes, the Merger will be a reorganization within the meaning of Section
368(a)(1) of the Code.

In addition to your request for our opinion on this specific matter of federal
income tax law, you have asked us to review the discussion of federal income tax
issues contained in the Registration Statement. We have reviewed the discussion
entitled "Certain Federal Income Tax Matters" contained in the Registration
Statement and believe that, insofar as it relates to statements of law and legal
conclusions, is correct in all material respects.

We consent to the reference to our firm under the caption "Certain Federal
Income Tax Matters" in the Proxy Statement included in the Registration
Statement and to the filing of this opinion as an exhibit to the Proxy Statement
and to the Registration Statement.

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. Further, no opinion is expressed
as to the federal income tax treatment with respect to holders of Company
Warrants.

No opinion is expressed as to any transaction other than the Merger as described
in the Reorganization Agreement, or as to any other 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,
administration 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.

<PAGE>   4

                        (iv) to determine the number of shares of Common Stock
to be covered by each Option granted hereunder;

                        (v) to approve forms of agreement for use under the

terms and conditions include, but are not limited to, the exercise price, the
time or times when Options may be exercised (which may be based on performance
criteria), any vesting acceleration or waiver of forfeiture restrictions, and
any restriction or limitation regarding any Option or the shares of Common Stock
relating thereto, based in each case on such factors as the Administrator, in
its sole discretion, shall determine;

                        (vii) to reduce the exercise price of any Option to the
then current Fair Market Value if the Fair Market Value of the Common Stock
covered by such Option shall have declined since the date the Option was

                        (viii) to institute an Option Exchange Program;

                        (ix) to construe and interpret the terms of the Plan and
awards granted pursuant to the Plan;

                        (x) to prescribe, amend and rescind rules and
regulations relating to the Plan, including rules and regulations relating to
sub-plans established for the purpose of qualifying for preferred tax treatment
under foreign tax laws;

                        (xi) to modify or amend each Option (subject to Section
15(b) of the Plan), including the discretionary authority to extend the
post-termination exercisability period of Options longer than is otherwise
provided for in the Plan;

                        (xii) to authorize any person to execute on behalf of
the Company any instrument required to effect the grant of an Option or
previously granted by the Administrator;

applicable to Options;

                        (xiv) to allow Optionees to satisfy withholding tax
obligations by electing to have the Company withhold from the Shares to be
issued upon exercise of an Option or Stock Purchase Right that number of Shares
having a Fair Market Value equal to the amount required to be withheld. The Fair
Market Value of the Shares to be withheld shall be determined on the date that
the amount of tax to be withheld is to be determined. All elections by an
Optionee to have Shares withheld for this purpose shall be made in such form and
under such conditions as the Administrator may deem necessary or advisable; and

                        (xv) to make all other determinations deemed necessary
or advisable for administering the Plan.

<PAGE>   5



               (c) Effect of Administrator's Decision. The Administrator's
decisions, determinations and interpretations shall be final and binding on all
Optionees and any other holders of Options.

        5.     Eligibility.  Options may be granted to Service Providers.

        6. Limitation. Neither the Plan nor any Option shall confer upon an
Optionee any right with respect to continuing the Optionee's relationship as a
Service Provider with the Company, nor shall they interfere in any way with the
Optionee's right or the Company's right to terminate such relationship at any
time, with or without cause.

        7. Term of Plan. The Plan shall become effective upon the later of (i)
its adoption by the Board and (ii) that date on which the Company first becomes
subject to the periodic reporting requirements of the Exchange Act. It shall
continue in effect until terminated under Section 14 of the Plan.

        8. Term of Option. The term of each Option shall be stated in the Option
Agreement.

        9.     Option Exercise Price and Consideration.

               (a) Exercise Price. The per share exercise price for the Shares
to be issued pursuant to exercise of an Option shall be determined by the
Administrator.

               (b) Waiting Period and Exercise Dates. At the time an Option is
granted, the Administrator shall fix the period within which the Option may be
exercised and shall determine any conditions which must be satisfied before the
Option may be exercised.

               (c) Form of Consideration. The Administrator shall determine the
acceptable form of consideration for exercising an Option, including the method
of payment. Such consideration may consist entirely of:

                        (i) cash;

                        (ii) check;

                        (iii) promissory note;

                        (iv) other Shares which (A) in the case of Shares
acquired upon exercise of an option, have been owned by the Optionee for more
than six months on the date of surrender, and (B) have a Fair Market Value on
the date of surrender equal to the aggregate exercise price of the Shares as to
which said Option shall be exercised;

                        (v) consideration received by the Company under a
cashless exercise program implemented by the Company in connection with the
Plan;


                                       -5-

<PAGE>   6

                        (vi) a reduction in the amount of any Company liability
to the Optionee, including any liability attributable to the Optionee's
participation in any Company-sponsored deferred compensation program or
arrangement;

                        (vii) such other consideration and method of payment for
the issuance of Shares to the extent permitted by Applicable Laws; or

                        (viii) any combination of the foregoing methods of
payment.

        10. Exercise of Option.

               (a) Procedure for Exercise; Rights as a Stockholder. Any Option
granted hereunder shall be exercisable according to the terms of the Plan and at
such times and under such conditions as determined by the Administrator and set
forth in the Option Agreement. An Option may not be exercised for a fraction of
a Share.

                   An Option shall be deemed exercised when the Company
receives: (i) written or electronic notice of exercise (in accordance with the
Option Agreement) from the person entitled to exercise the Option, and (ii) full
payment for the Shares with respect to which the Option is exercised. Full
payment may consist of any consideration and method of payment authorized by the
Administrator and permitted by the Option Agreement and the Plan. Shares issued
upon exercise of an Option shall be issued in the name of the Optionee or, if
requested by the Optionee, in the name of the Optionee and his or her spouse.
Until the Shares are issued (as evidenced by the appropriate entry on the books
of the Company or of a duly authorized transfer agent of the Company), no right
to vote or receive dividends or any other rights as a stockholder shall exist
with respect to the Optioned Stock, notwithstanding the exercise of the Option.
The Company shall issue (or cause to be issued) such Shares promptly after the
Option is exercised. No adjustment will be made for a dividend or other right
for which the record date is prior to the date the Shares are issued, except as
provided in Section 12 of the Plan.

                   Exercising an Option in any manner shall decrease the number
of Shares thereafter available, both for purposes of the Plan and for sale under
the Option, by the number of Shares as to which the Option is exercised.

               (b) Termination of Relationship as a Service Provider. If an
Optionee ceases to be a Service Provider, other than upon the Optionee's death
or Disability, the Optionee may exercise his or her Option, but only within such
period of time as is specified in the Option Agreement, and only to the extent
that the Option is vested on the date of termination (but in no event later than
the expiration of the term of such Option as set forth in the Option Agreement).
In the absence of a specified time in the Option Agreement, the Option shall
remain exercisable for three (3) months following the Optionee's termination.
If, on the date of termination, the Optionee is not vested as to his or her
entire Option, the Shares covered by the unvested portion of the Option shall
revert to the Plan. If, after termination, the Optionee does not exercise his or
her Option within the time specified by the Administrator, the Option shall
terminate, and the Shares covered by such Option shall revert to the Plan.

                                       -6-

<PAGE>   7

               (c) Disability of Optionee. If an Optionee ceases to be a Service
Provider as a result of the Optionee's Disability, the Optionee may exercise his
or her Option within such period of time as is specified in the Option
Agreement, to the extent the Option is vested on the date of termination (but in
no event later than the expiration of the term of such Option as set forth in
the Option Agreement). In the absence of a specified time in the Option
Agreement, the Option shall remain exercisable for twelve (12) months following
the Optionee's termination. If, on the date of termination, the Optionee is not
vested as to his or her entire Option, the Shares covered by the unvested
portion of the Option shall revert to the Plan. If, after termination, the
Optionee does not exercise his or her Option within the time specified herein,
the Option shall terminate, and the Shares covered by such Option shall revert
to the Plan.

               (d) Death of Optionee. If an Optionee dies while a Service
Provider, the Option may be exercised within such period of time as is specified
in the Option Agreement (but in no event later than the expiration of the term
of such Option as set forth in the Notice of Grant), by the Optionee's estate or
by a person who acquires the right to exercise the Option by bequest or
inheritance, but only to the extent that the Option is vested on the date of
death. In the absence of a specified time in the Option Agreement, the Option
shall remain exercisable for twelve (12) months following the Optionee's
termination. If, at the time of death, the Optionee is not vested as to his or
her entire Option, the Shares covered by the unvested portion of the Option
shall immediately revert to the Plan. The Option may be exercised by the
executor or administrator of the Optionee's estate or, if none, by the person(s)
entitled to exercise the Option under the Optionee's will or the laws of descent
or distribution. If the Option is not so exercised within the time specified
herein, the Option shall terminate, and the Shares covered by such Option shall
revert to the Plan.

               (e) Buyout Provisions. The Administrator may at any time offer to
buy out for a payment in cash or Shares, an Option previously granted based on
such terms and conditions as the Administrator shall establish and communicate
to the Optionee at the time that such offer is made.

        11. Nontransferability of Options . Unless determined otherwise by the
Administrator, an Option may not be sold, pledged, assigned, hypothecated,
transferred, or disposed of in any manner other than by will or by the laws of
descent or distribution and may be exercised, during the lifetime of the
Optionee, only by the Optionee. If the Administrator makes an Option
transferable, such Option shall contain such additional terms and conditions as
the Administrator deems appropriate.

        12. Adjustments Upon Changes in Capitalization, Dissolution, Merger or
Asset Sale.

               (a) Changes in Capitalization. Subject to any required action by
the Stockholders of the Company, the number of shares of Common Stock covered by
each outstanding Option, and the number of shares of Common Stock which have
been authorized for issuance under the Plan but as to which no Options have yet
been granted or which have been returned to the Plan upon cancellation or
expiration of an Option, as well as the price per share of Common Stock covered
by each such outstanding Option, shall be proportionately adjusted for any
increase or decrease in the number of issued shares of Common Stock resulting
from a stock split, reverse stock split, stock dividend, combination or
reclassification of the Common Stock, or any other increase or decrease in the
number of issued shares of Common Stock effected without receipt of
consideration by the Company; provided, however, that conversion of any
convertible securities of the Company shall not be deemed to have been


                                       -7-

<PAGE>   8

"effected without receipt of consideration." Such adjustment shall be made by
the Board, whose determination in that respect shall be final, binding and
conclusive. Except as expressly provided herein, no issuance by the Company of
shares of stock of any class, or securities convertible into shares of stock of
any class, shall affect, and no adjustment by reason thereof shall be made with
respect to, the number or price of shares of Common Stock subject to an Option.

               (b) Dissolution or Liquidation. In the event of the proposed
dissolution or liquidation of the Company, the Administrator shall notify each
Optionee as soon as practicable prior to the effective date of such proposed
transaction. The Administrator in its discretion may provide for an Optionee to
have the right to exercise his or her Option until ten (10) days prior to such
transaction as to all of the Optioned Stock covered thereby, including Shares as
to which the Option would not otherwise be exercisable. In addition, the
Administrator may provide that any Company repurchase option applicable to any
Shares purchased upon exercise of an Option shall lapse as to all such Shares,
provided the proposed dissolution or liquidation takes place at the time and in
the manner contemplated. To the extent it has not been previously exercised, an
Option will terminate immediately prior to the consummation of such proposed
action.

               (c) Change of Control. In the event of a Change of Control
(defined below), Options under this Plan shall be assumed or an equivalent
option shall be substituted by any successor corporation or a Parent or
Subsidiary of such successor corporation. If, in such event the Option is not
assumed or substituted, the Option shall terminate as of the date of closing of
the Change of Control. For purposes of this paragraph, the Option shall be
considered assumed if, following the Change of Control, the Option confers the
right to purchase, for each share of Optioned Stock subject to the Option
immediately prior to the Change of Control, the consideration (whether stock,
cash or other securities or property) received in the Change of Control by
holders of Common Stock for each Share held on the effective date of the
transaction (and, if holders were offered a choice of consideration, the type of
consideration chosen by the holders of a majority of the outstanding Shares);
provided, however, that if such consideration received in the Change of Control
was not solely Common Stock of the successor corporation or its Parent, the
Administrator may, with the consent of the successor corporation, provide for
the consideration to be received upon the exercise of the Option, for each share
of Optioned Stock subject to the Option, to be solely Common Stock of the
successor corporation or its Parent equal and fair market value to the per share
consideration received by the holders of Common Stock in the Change of Control.
For purposes of this Plan, "Change of Control" shall mean a corporate
reorganization of the Company which results in the then current stockholders of
the Company holding less than 50% of the equity securities of the surviving
company, or the sale of all or substantially all of the assets of the Company.

        13. Date of Grant. The date of grant of an Option shall be, for all
purposes, the date on which the Administrator makes the determination granting
such Option, or such other later date as is determined by the Administrator.
Notice of the determination shall be provided to each Optionee within a
reasonable time after the date of such grant.

        14. Amendment and Termination of the Plan.

               (a) Amendment and Termination. The Board may at any time amend,
alter, suspend or terminate the Plan.

               (b) Effect of Amendment or Termination. No amendment, alteration,
suspension or termination of the Plan shall impair the rights of any Optionee,
unless mutually agreed otherwise between the Optionee and the Administrator,
which agreement must be in writing and signed by the Optionee and the Company.
Termination of the Plan shall not affect the Administrator's ability to exercise
the powers granted to it hereunder with respect to options granted under the
Plan prior to the date of such termination.

        15. Conditions Upon Issuance of Shares.

               (a) Legal Compliance. Shares shall not be issued pursuant to the
exercise of an Option unless the exercise of such Option and the issuance and
delivery of such Shares shall comply with Applicable Laws and shall be further
subject to the approval of counsel for the Company with respect to such
compliance.

               (b) Inability to Obtain Authority. The inability of the Company
to obtain authority from any regulatory body having jurisdiction, which
authority is deemed by the Company's counsel to be necessary to the lawful
issuance and sale of any Shares hereunder, shall relieve the Company of any
liability in respect of the failure to issue or sell such Shares as to which
such requisite authority shall not have been obtained.

        16. Reservation of Shares. The Company, during the term of this Plan,
will at all times reserve and keep available such number of Shares as shall be
sufficient to satisfy the requirements of the Plan.

II.     AGREEMENT

        1. Grant of Option. The Plan Administrator of the Company hereby grants
to the Optionee named in the Notice of Grant attached as Part I of this
Agreement (the "Optionee") an option (the "Option") to purchase the number of
Shares, as set forth in the Notice of Grant, at the exercise price per share set
forth in the Notice of Grant (the "Exercise Price"), subject to the terms and
conditions of the Plan, which is incorporated herein by reference. Subject to
Section 14(b) of the Plan, in the event of a conflict between the terms and
conditions of the Plan and the terms and conditions of this Option Agreement,
the terms and conditions of the Plan shall prevail.

        2.     Exercise of Option.

               (a) Right to Exercise. This Option is exercisable during its term
in accordance with the Vesting Schedule set out in the Notice of Grant and the
applicable provisions of the Plan and this Option Agreement.

               (b) Method of Exercise. This Option is exercisable by delivery of
an exercise notice, in the form attached as Exhibit A (the "Exercise Notice"),
which shall state the election to exercise the Option, the number of Shares in
respect of which the Option is being exercised (the "Exercised Shares"), and
such other representations and agreements as may be required by the Company
pursuant to the provisions of the Plan. The Exercise Notice shall be completed
by the Optionee and delivered to the Company. The Exercise Notice shall be
accompanied by payment of the aggregate Exercise Price as to all Exercised
Shares. This Option shall be deemed to be exercised upon receipt by the Company
of such fully executed Exercise Notice accompanied by such aggregate Exercise
Price.

               No Shares shall be issued pursuant to the exercise of this Option
unless such issuance and exercise complies with Applicable Laws. Assuming such
compliance, for income tax purposes the Exercised Shares shall be considered
transferred to the Optionee on the date the Option is exercised with respect to
such Exercised Shares.

        3. Method of Payment. Payment of the aggregate Exercise Price shall be
by any of the following, or a combination thereof, at the election of the
Optionee:

               (a)    cash; or

               (b)    check; or

               (c) consideration received by the Company under a cashless
exercise program implemented by the Company in connection with the Plan; or

               (d) surrender of other Shares which (i) in the case of Shares
acquired upon exercise of an option, have been owned by the Optionee for more
than six (6) months on the date of surrender, AND (ii) have a Fair Market Value
on the date of surrender equal to the aggregate Exercise Price of the Exercised
Shares; or

<PAGE>   12

        4. Nontransferability of Option. This Option may not be transferred in
any manner otherwise than by will or by the laws of descent or distribution and
may be exercised during the lifetime of Optionee only by the Optionee. The terms
of the Plan and this Option Agreement shall be binding upon the executors,
administrators, heirs, successors and assigns of the Optionee.

        5. Term of Option. This Option may be exercised only within the term set
out in the Notice of Grant, and may be exercised during such term only in
accordance with the Plan and the terms of this Option Agreement.

        6. Change of Control. In the event of a Change of Control, this Option
shall be exercisable in accordance with Section 12(c) of the Plan
notwithstanding anything to the contrary set forth elsewhere herein.

        7. Arbitration. Any dispute or claim arising out of or in connection
with this Agreement shall be settled by binding arbitration. Any such
arbitration shall be conducted in accordance with the Rules of Conciliation and
Arbitration of the American Arbitration Association and shall take place in San
Jose, California. The arbitration shall be conducted by one arbitrator; provided
that if the parties cannot agree on a single arbitrator, then the arbitration
shall be conducted by a panel of three arbitrators, one selected by each party
and the third selected by the other two arbitrators. The determination of the
arbitrator(s) shall be final and binding upon the parties.

        8. Tax Consequences. Some of the federal tax consequences relating to
this Option, as of the date of this Option, are set forth below. THIS SUMMARY IS
NECESSARILY INCOMPLETE, AND THE TAX LAWS AND REGULATIONS ARE SUBJECT TO CHANGE.
THE OPTIONEE SHOULD CONSULT A TAX ADVISER BEFORE EXERCISING THIS OPTION OR
DISPOSING OF THE SHARES.

               (a) Exercising the Option. The Optionee may incur regular federal
income tax liability upon exercise of an NSO. The Optionee will be treated as
having received compensation income (taxable at ordinary income tax rates) equal
to the excess, if any, of the Fair Market Value of the Exercised Shares on the
date of exercise over their aggregate Exercise Price. If the Optionee is an
Employee or a former Employee, the Company will be required to withhold from his
or her compensation or collect from Optionee and pay to the applicable taxing
authorities an amount in cash equal to a percentage of this compensation income
at the time of exercise, and may refuse to honor the exercise and refuse to
deliver Shares if such withholding amounts are not delivered at the time of
exercise.

               (b) Disposition of Shares. If the Optionee holds NSO Shares for
at least one year, any gain realized on disposition of the Shares will be
treated as long-term capital gain for federal income tax purposes.

               (n) "Reserves" shall mean the number of shares of Common Stock
covered by each option under the Plan which have not yet been exercised and the

Offering Periods. The Board shall have the power to change the duration of
Offering Periods (including the commencement dates thereof) with respect to
future offerings without stockholder approval if such change is announced at

may elect to have deducted pursuant to the Plan or the maximum aggregate amount
which may be withheld in any Offering Period (subject to any limit imposed by
the Code).

               (b) All payroll deductions made for a participant shall be
credited to his or her account under the Plan and shall be withheld in whole
percentages only. A participant may not make any additional payments into such
account.

               (c) A participant may discontinue his or her participation in the
Plan as provided in Section 10 hereof, or may increase or decrease the rate of
his or her payroll deductions during the Offering Period by completing or filing
with the Company a new subscription agreement authorizing a change in payroll
deduction rate. The Board may, in its discretion, limit the number of
participation rate changes during any Offering Period. The change in rate shall
be effective with the first full payroll period following five (5) business days
after the Company's receipt of the new subscription agreement unless the Company
elects to process a given change in participation more quickly. A participant's
subscription agreement shall remain in effect for successive Offering Periods
unless terminated as provided in Section 10 hereof.

               (d) Notwithstanding the foregoing, to the extent necessary to
comply with Section 423(b)(8) of the Code and Section 3(b) hereof, a
participant's payroll deductions may be decreased to zero percent (0%) at any
time during an Offering Period. Payroll deductions shall recommence at the rate
provided in such participant's subscription agreement at the beginning of the
first Offering Period which is scheduled to end in the following calendar year,
unless terminated by the participant as provided in Section 10 hereof.

               (e) At the time the option is exercised, in whole or in part, or
at the time some or all of the Company's Common Stock issued under the Plan is
disposed of, the participant must make adequate provision for the Company's
federal, state, or other tax withholding obligations, if any, which arise upon
the exercise of the option or the disposition of the Common Stock. At any time,
the Company may, but shall not be obligated to, withhold from the participant's
compensation the amount necessary for the Company to meet applicable withholding
obligations, including any withholding required to make available to the Company
any tax deductions or benefits attributable to sale or early disposition of
Common Stock by the Employee.

        7. Grant of Option. On the Enrollment Date of each Offering Period, each
eligible Employee participating in such Offering Period shall be granted an
option to purchase on the Exercise Date of such Offering Period (at the
applicable Purchase Price) up to a number of shares of the Company's Common
Stock determined by dividing such Employee's payroll deductions accumulated
prior to such Exercise Date and retained in the Participant's account as of the
Exercise Date by the applicable Purchase Price; provided that such purchase
shall be subject to the limitations set forth in Sections 3(b) and 12 hereof.
Exercise of the option shall occur as provided in Section 8 hereof, unless the
participant has withdrawn pursuant to Section 10 hereof. The Option shall expire
on the last day of the Offering Period.

        8. Exercise of Option. Unless a participant withdraws from the Plan as
provided in Section 10 hereof, his or her option for the purchase of shares
shall be exercised automatically on the Exercise Date, and the maximum number of
full shares subject to option shall be purchased for such

                                       -4-

<PAGE>   5

participant at the applicable Purchase Price with the accumulated payroll
deductions in his or her account. No fractional shares shall be purchased; any
payroll deductions accumulated in a participant's account which are not
sufficient to purchase a full share shall be retained in the participant's
account for the subsequent Offering Period, subject to earlier withdrawal by the
participant as provided in Section 10 hereof. Any other monies left over in a
participant's account after the Exercise Date shall be returned to the
participant. During a participant's lifetime, a participant's option to purchase
shares hereunder is exercisable only by him or her.

        9. Delivery. As promptly as practicable after each Exercise Date on
which a purchase of shares occurs, the Company shall arrange the delivery to
each participant, as appropriate, of a certificate representing the shares
purchased upon exercise of his or her option.

        10.    Withdrawal.

               (a) A participant may withdraw all but not less than all the
payroll deductions credited to his or her account and not yet used to exercise
his or her option under the Plan at any time by giving written notice to the
Company in the form of Exhibit B to this Plan. All of the participant's payroll
deductions credited to his or her account shall be paid to such participant
promptly after receipt of notice of withdrawal and such participant's option for
the Offering Period shall be automatically terminated, and no further payroll
deductions for the purchase of shares shall be made for such Offering Period. If
a participant withdraws from an Offering Period, payroll deductions shall not
resume at the beginning of the succeeding Offering Period unless the participant
delivers to the Company a new subscription agreement.

               (b) A participant's withdrawal from an Offering Period shall not
have any effect upon his or her eligibility to participate in any similar plan
which may hereafter be adopted by the Company or in succeeding Offering Periods
which commence after the termination of the Offering Period from which the
participant withdraws.

        11. Termination of Employment. Upon a participant's ceasing to be an
Employee for any reason, he or she shall be deemed to have elected to withdraw
from the Plan and the payroll deductions credited to such participant's account
during the Offering Period but not yet used to exercise the option shall be
returned to such participant or, in the case of his or her death, to the person
or persons entitled thereto under Section 15 hereof, and such participant's
option shall be automatically terminated. The preceding sentence
notwithstanding, a participant who receives payment in lieu of notice of
termination of employment shall be treated as continuing to be an Employee for
the participant's customary number of hours per week of employment during the
period in which the participant is subject to such payment in lieu of notice.

        12. Interest. No interest shall accrue on the payroll deductions of a
participant in the Plan.

        13. Stock.

               (a) The maximum number of shares of the Company's Common Stock
which shall be made available for sale under the Plan shall be Four Hundred
Thousand (400,000) shares (after giving effect to a one-for-four reverse split
of the Common Stock approved by the Board on December 5, 1996),

                                       -5-

<PAGE>   6

subject to adjustment upon changes in capitalization of the Company as provided
in Section 19 hereof. If, on a given Exercise Date, the number of shares with
respect to which options are to be exercised exceeds the number of shares then
available under the Plan, the Company shall make a pro rata allocation of the
shares remaining available for purchase in as uniform a manner as shall be
practicable and as it shall determine to be equitable.

               (b) The participant shall have no interest or voting right in
shares covered by his option until such option has been exercised.

               (c) Shares to be delivered to a participant under the Plan shall
be registered in the name of the participant or in the name of the participant
and his or her spouse.

        14. Administration. The Plan shall be administered by the Board or a
committee of members of the Board appointed by the Board. The Board or its
committee shall have full and exclusive discretionary authority to construe,
interpret and apply the terms of the Plan, to determine eligibility and to
adjudicate all disputed claims filed under the Plan. Every finding, decision and
determination made by the Board or its committee shall, to the full extent
permitted by law, be final and binding upon all parties.

        15.    Designation of Beneficiary.

               (a) A participant may file a written designation of a beneficiary
who is to receive any shares and cash, if any, from the participant's account
under the Plan in the event of such participant's death subsequent to an
Exercise Date on which the option is exercised but prior to delivery to such
participant of such shares and cash. In addition, a participant may file a
written designation of a beneficiary who is to receive any cash from the
participant's account under the Plan in the event of such participant's death
prior to exercise of the option. If a participant is married and the designated
beneficiary is not the spouse, spousal consent shall be required for such
designation to be effective.

               (b) Such designation of beneficiary may be changed by the
participant at any time by written notice. In the event of the death of a
participant and in the absence of a beneficiary validly designated under the
Plan who is living at the time of such participant's death, the Company shall
deliver such shares and/or cash to the executor or administrator of the estate
of the participant, or if no such executor or administrator has been appointed
(to the knowledge of the Company), the Company, in its discretion, may deliver
such shares and/or cash to the spouse or to any one or more dependents or
relatives of the participant, or if no spouse, dependent or relative is known to
the Company, then to such other person as the Company may designate.

        16. Transferability. Neither payroll deductions credited to a
participant's account nor any rights with regard to the exercise of an option or
to receive shares under the Plan may be assigned, transferred, pledged or
otherwise disposed of in any way (other than by will, the laws of descent and
distribution or as provided in Section 15 hereof) by the participant. Any such
attempt at assignment, transfer, pledge or other disposition shall be without
effect, except that the Company may treat such act as an election to withdraw
funds from an Offering Period in accordance with Section 10 hereof.


                                       -6-

<PAGE>   7

        17. Use of Funds. All payroll deductions received or held by the Company
under the Plan may be used by the Company for any corporate purpose, and the
Company shall not be obligated to segregate such payroll deductions.

        18. Reports. Individual accounts shall be maintained for each
participant in the Plan. Statements of account shall be given to participating
Employees at least annually, which statements shall set forth the amounts of
payroll deductions, the Purchase Price, the number of shares purchased and the
remaining cash balance, if any.

        19.    Adjustments Upon Changes in Capitalization, Dissolution,
               Liquidation, Merger or Asset Sale.

               (a) Changes in Capitalization. Subject to any required action by
the stockholders of the Company, the Reserves, the maximum number of shares each
participant may purchase per Offering Period (pursuant to Section 7), as well as
the price per share and the number of shares of Common Stock covered by each
option under the Plan which has not yet been exercised shall be proportionately
adjusted for any increase or decrease in the number of issued shares of Common
Stock resulting from a stock split, reverse stock split, stock dividend,
combination or reclassification of the Common Stock, or any other increase or
decrease in the number of shares of Common Stock effected without receipt of
consideration by the Company; provided, however, that conversion of any
convertible securities of the Company shall not be deemed to have been "effected
without receipt of consideration." Such adjustment shall be made by the Board,
whose determination in that respect shall be final, binding and conclusive.
Except as expressly provided herein, no issuance by the Company of shares of
stock of any class, or securities convertible into shares of stock of any class,
shall affect, and no adjustment by reason thereof shall be made with respect to,
the number or price of shares of Common Stock subject to an option.

               (b) Dissolution or Liquidation. In the event of the proposed
dissolution or liquidation of the Company, the Offering Period shall terminate
immediately prior to the consummation of such proposed action, unless otherwise
provided by the Board.

               (c) Merger or Asset Sale. In the event of a proposed sale of all
or substantially all of the assets of the Company, or the merger of the Company
with or into another corporation, the Offering Period then in progress shall be
shortened by setting a new Exercise Date (the "New Exercise Date"). The New
Exercise Date shall be before the date of the Company's proposed sale or merger.
The Board shall notify each participant in writing, at least ten (10) business
days prior to the New Exercise Date, that the Exercise Date for the
participant's option has been changed to the New Exercise Date and that the
participant's option shall be exercised automatically on the New Exercise Date,
unless prior to such date the participant has withdrawn from the Offering Period
as provided in Section 10 hereof.

        20.    Amendment or Termination.

               (a) The Board of Directors of the Company may at any time and for
any reason terminate or amend the Plan. Except as provided in Section 19 hereof,
no such termination can affect options previously granted, provided that an
Offering Period may be terminated by the Board of Directors on any Exercise Date
if the Board determines that the termination of the Plan is in the best
interests of the Company and its stockholders. Except as provided in Section 19
hereof, no amendment

                                       -7-

<PAGE>   8

may make any change in any option theretofore granted which adversely affects
the rights of any participant. To the extent necessary to comply with Section
423 of the Code (or any other applicable law, regulation or stock exchange
rule), the Company shall obtain shareholder approval in such a manner and to
such a degree as required.

               (b) Without stockholder consent and without regard to whether any
participant rights may be considered to have been "adversely affected," the
Board (or its committee) shall be entitled to change the Offering Periods, limit
the frequency and/or number of changes in the amount withheld during an Offering
Period, establish the exchange ratio applicable to amounts withheld in a
currency other than U.S. dollars, permit payroll withholding in excess of the
amount designated by a participant in order to adjust for delays or mistakes in
the Company's processing of properly completed withholding elections, establish
reasonable waiting and adjustment periods and/or accounting and crediting
procedures to ensure that amounts applied toward the purchase of Common Stock
for each participant properly correspond with amounts withheld from the
participant's Compensation, and establish such other limitations or procedures
as the Board (or its committee) determines in its sole discretion advisable
which are consistent with the Plan.

        21. Notices. All notices or other communications by a participant to the
Company under or in connection with the Plan shall be deemed to have been duly
given when received in the form specified by the Company at the location, or by
the person, designated by the Company for the receipt thereof.

        22. Conditions Upon Issuance of Shares. Shares shall not be issued with
respect to an option unless the exercise of such option and the issuance and
delivery of such shares pursuant thereto shall comply with all applicable
provisions of law, domestic or foreign, including, without limitation, the
Securities Act of 1933, as amended, the Securities Exchange Act of 1934, as
amended, the rules and regulations promulgated thereunder, and the requirements
of any stock exchange upon which the shares may then be listed, and shall be
further subject to the approval of counsel for the Company with respect to such
compliance.

        As a condition to the exercise of an option, the Company may require the
person exercising such option to represent and warrant at the time of any such
exercise that the shares are being purchased only for investment and without any
present intention to sell or distribute such shares if, in the opinion of
counsel for the Company, such a representation is required by any of the
aforementioned applicable provisions of law.

        23. Term of Plan. The Plan shall become effective upon the later to
occur of (i) its adoption by the Board of Directors and (ii) that date on which
the Company first becomes subject to the periodic reporting requirements of the
Securities Exchange Act of 1934, as amended. It shall continue in effect for a
term of ten (10) years unless sooner terminated under Section 20 hereof.

                             SUBSCRIPTION AGREEMENT



_____ Original Application                           Enrollment Date: __________
_____ Change in Payroll Deduction Rate
_____ Change of Beneficiary(ies)


1.      _____________________________________ hereby elects to participate in
        the Storage Dimensions, Inc. 1996 Employee Stock Purchase Plan (the
        "Employee Stock Purchase Plan") and subscribes to purchase shares of the
        Company's Common Stock in accordance with this Subscription Agreement
        and the Employee Stock Purchase Plan.

2.      I hereby authorize payroll deductions from each paycheck in the amount
        of ____% of my Compensation on each payday (from 1 to 15%) during the
        Offering Period in accordance with the Employee Stock Purchase Plan.
        (Please note that no fractional percentages are permitted.)

3.      I understand that said payroll deductions shall be accumulated for the
        purchase of shares of Common Stock at the applicable Purchase Price
        determined in accordance with the Employee Stock Purchase Plan. I
        understand that if I do not withdraw from an Offering Period, any
        accumulated payroll deductions will be used to automatically exercise my
        option.

4.      I have received a copy of the complete Employee Stock Purchase Plan. I
        understand that my participation in the Employee Stock Purchase Plan is
        in all respects subject to the terms of the Plan. I understand that my
        ability to exercise the option under this Subscription Agreement is
        subject to stockholder approval of the Employee Stock Purchase Plan.

5.      Shares purchased for me under the Employee Stock Purchase Plan should be
        issued in the name(s) of (Employee or Employee and Spouse only): _____ .

6.      I understand that if I dispose of any shares received by me pursuant to
        the Plan within 2 years after the Enrollment Date (the first day of the
        Offering Period during which I purchased such shares), I will be treated
        for federal income tax purposes as having received ordinary income at
        the time of such disposition in an amount equal to the excess of the
        fair market value of the shares at the time such shares were purchased
        by me over the price which I paid for the shares. I hereby agree to
        notify the Company in writing within 30 days after the date of any
        disposition of shares and I will make adequate provision for Federal,
        state or other tax withholding obligations, if any, which arise upon
        the disposition of the Common Stock. The Company may, but will not be
        obligated to, withhold from my compensation the amount necessary to meet
        any applicable withholding obligation including any withholding
        necessary to make available to the


<PAGE>   10

        Company any tax deductions or benefits attributable to sale or early
        disposition of Common Stock by me. If I dispose of such shares at any
        time after the expiration of the 2-year holding period, I understand
        that I will be treated for federal income tax purposes as having
        received income only at the time of such disposition, and that such
        income will be taxed as ordinary income only to the extent of an amount
        equal to the lesser of (1) the excess of the fair market value of the
        shares at the time of such disposition over the purchase price which I
        paid for the shares, or (2) 15% of the fair market value of the shares
        on the first day of the Offering Period. The remainder of the gain, if
        any, recognized on such disposition will be taxed as capital gain.

7.      I hereby agree to be bound by the terms of the Employee Stock Purchase
        Plan. The effectiveness of this Subscription Agreement is dependent upon
        my eligibility to participate in the Employee Stock Purchase Plan.

8.      In the event of my death, I hereby designate the following as my
        beneficiary(ies) to receive all payments and shares due me under the
        Employee Stock Purchase Plan:

        2.1 RESTRICTIONS ON ACTIONS OF PARENT SECURITIES. Except as permitted by
Section 2.2 and subject to the terms of this Agreement, each Stockholder agrees
that, from the date hereof until the earlier to occur of (i) the date that is
five (5) years from the Closing Date, and (ii) the date on which the
Stockholders and their affiliates beneficially hold in the aggregate less than
five percent (5%) of the outstanding voting stock of Parent (such earlier date
being referred to as the "Termination Date"), it shall not (acting individually
or in conjunction with one or more other Stockholders) nor shall it permit any
of its affiliates to:

               (a) acquire or offer to acquire or agree to acquire, directly or
indirectly, by purchase or otherwise, any Parent Securities not already owned,
beneficially or of record, by the Stockholders as of the date hereof, except for
Parent Securities issued to the Stockholders in connection with any stock split
or other reclassification affecting the outstanding securities of Parent or
stock dividend or other pro rata distribution by Parent to holders of its
outstanding securities;

               (b) solicit proxies or become a "participant" in a "solicitation"
(as such terms are defined in Regulation 14A under the Securities Exchange Act
of 1934, as amended (the "Exchange Act")) with respect to any matter involving
Parent or otherwise initiate, propose or solicit any stockholder, or induce any
other person to initiate any stockholder proposal or a tender offer for shares
of Parent Securities or any change of control of Parent, or for the purpose of
convening a stockholders' meeting of Parent;

               (c) deposit any Parent Securities in any voting trust or subject
them to any voting agreement or other agreement of similar effect (other than
the Voting Agreements entered into in connection with the Merger Agreement);

               (d) join any partnership, limited partnership, syndicate, or
other group for the purpose of acquiring, holding or disposing of Parent
Securities within the meaning of Section 13(d) of the Exchange Act;

               (e) acquire or offer to acquire or hold, or agree to acquire or
hold, directly or indirectly or permit any person or entity under any
Stockholder's control to acquire, offer to acquire or hold, or agree to acquire
or hold, directly or indirectly, by purchase or otherwise, more than five
percent (5%) of any class of equity securities of any entity which is the
beneficial owner of more than five percent (5%) of the outstanding voting power
of Parent Securities; or

               (f) otherwise take any action individually or jointly with any
partnership, limited partnership, syndicate, or other group or assist any other
person, corporation, entity or group in taking any action it could not
individually take under this Agreement.

        2.2 PERMITTED ACQUISITIONS.

               (a) Notwithstanding the limitations imposed on the Stockholders
and their affiliates under Section 2.1 of this Agreement, one or more
Stockholders or their affiliates may acquire from time to time up to that number
of Parent Securities such that immediately following each such acquisition, the
total number of Parent Securities owned beneficially or of record by all
Stockholders and all of their respective affiliates together does not exceed
that percentage of the Common Stock of Parent (the "Maximum Percentage"),
calculated after giving pro forma effect to the exercise of all outstanding
options and warrants and the conversion of all outstanding securities
convertible into Common Stock of Parent, held by all Stockholders and their
affiliates immediately after the Effective Time. Any Stockholder or its
affiliates that acquire shares of Parent Securities under this Section 2 shall,
promptly following such acquisition, provide written notice of such acquisition
to Parent or, if such acquisition is prior to the Closing Date, to the Company.

                  (b) If, as a result of any purchase or other acquisition of
securities of Parent other than pursuant to the provisions set forth above in
Section 2(a), any Stockholder or affiliate thereof shall at any time own any
Parent Securities such that the total number of Parent Securities owned by all
Stockholders and their affiliates together exceeds the maximum percentage
permitted by this Section 2 (such excess securities so purchased or otherwise
acquired shall be referred to as "Prohibited Securities"), subject to the
provisions of all applicable securities laws, such Stockholder shall sell as
promptly as practicable Parent Securities having voting power at least equal to
the voting power of the Prohibited Securities. Prior to such sale, each
Stockholder agrees, and hereby grants Parent its irrevocable proxy, to vote the
Prohibited Securities in accordance with the recommendation of the Parent's
management in any matter submitted to a vote of the stockholders of Parent
(provided, however, that the foregoing paragraph shall not be deemed to limit
Parent's remedies in the event that Prohibited Securities were acquired in
violation of this Section 2). Notwithstanding the foregoing, if the aggregate
beneficial ownership of the Stockholders and their affiliates exceeds the
Maximum Percentage solely as a result of any stock repurchase or other action
effected by Parent or the Company which has the effect of reducing the number of
outstanding Parent capital stock, then securities of Parent held by the
Stockholders shall not be deemed to be Prohibited Securities and the provisions
of this Section 2.2(b) shall not be applicable to any such excess holdings.

SECTION 3. WAIVER OF RESTRICTIONS. The provisions of this Agreement may be
waived with respect to any proposed acquisition or transfer of Parent Securities
solely (i) after the Closing Date by Parent and (ii) prior to the Closing Date
by Parent and the Company, upon duly authorized action of their respective
Boards of Directors.

SECTION 4. REPRESENTATIONS AND WARRANTIES OF STOCKHOLDER

        Each Stockholder hereby represents and warrants to Parent and the

        5.3 SEVERABILITY. Any term or provision of this Agreement which is
invalid or unenforceable in any jurisdiction shall, as to that jurisdiction, be

not performed in accordance with its specific terms or was otherwise breached.
It is accordingly agreed that the parties shall be entitled to an injunction or

                                   WITNESSETH:

        WHEREAS, Employer and Employee entered into an Employment Agreement on
December 22, 1992 (the "Agreement") by which Employee currently serves as
President and Chief Executive Officer of Employer;

        WHEREAS, Employer and Employee now desire to amend the Agreement to
change the benefits payable to Employee in the event of termination of
Employee's employment or consulting relationship with Employer.

        NOW, THEREFORE, in consideration of the premises, the covenants
contained herein, and other good and valuable consideration, the Employer and
the Employee hereby amend the Agreement as follows:

        1. Amendment to Section 2.1 of the Agreement. Section 2.1 of the
Agreement is hereby amended to add the following sentence as a new penultimate

Agreement is hereby amended to read in its entirety as follows:

                "(b) In addition, for so long as Employee continues to be
        engaged by Employer or any subsidiary thereof as an employee or a
        consultant and for the period during which Employer or any subsidiary
        thereof makes severance payments to Employee pursuant to

<PAGE>   2


        Section 5.3(a), Employee will not, without the express written consent
        of Employer, directly or indirectly engage, participate or invest in or
        assist, as owner, part owner, shareholder, partner, director, officer,
        trustee, employee, agent or consultant, or in any other capacity, any
        business organization other than Employer whose activities or products
        are competitive with activities or products of Employer or any
        subsidiary thereof in which activities Employee shall have participated
        or as to which products Employee shall have had responsibility either in
        their development, marketing or otherwise, provided that Employee may
        make passive investments in a competitive enterprise the shares of which
        are publicly traded if Employee's investment constitutes less than 5% of
        the outstanding shares of such enterprise. The foregoing agreement not
        to compete shall apply in any and all cities and counties of each state
        of the United States of America in which the activities of Employer or
        any subsidiary thereof shall have been conducted, or the products of any

Agreement is hereby amended to add the following sentence to the end of Section

        which is a subsidiary of the foregoing during the period in which the
        noncompetition agreement set forth in Section 4.1 is in effect."

        5. Amendment to Section 5.1 of the Agreement. Section 5.1 of the
Agreement is hereby amended to add the following language to the end thereof:

                (a) Section 5.2(b) is hereby amended to delete the phrase
        "thirty (30) days" from the first sentence thereof.

                (b) Section 5.2(b) of the Agreement is hereby amended to add the
        following language to the end of Section 5.2(b):

                      "Any termination of Employee's status as an employee or
               consultant of the Employer (but not a change in status from
               employee to consultant) following a "Change in Control", whether
               at Employer's or Employee's option (other than a termination by
               Employer under Section 5.2(c)), shall be deemed to be a
               termination by Employer pursuant to this Section 5.2(b) and
               Employer shall make severance payments as provided in Section
               5.3(a). "Change of Control" shall mean any merger or sale of
               substantially all of the assets of the Employer or other
               transaction pursuant to which the stockholders of Employer before
               such transaction no longer hold at least 50% of the voting
               securities of the Employer after such transaction. In no event,
               however, shall the change in Employee's title

                                       -2-

<PAGE>   3

               contemplated under Section 2.1 of this Agreement, as amended, or
               any commensurate change in Employee's duties be a termination
               pursuant to this Section 5.2(b) or trigger Employer's obligation
               to make severance payments under Section 5.3(a)."

                (c) Section 5.2 of the Agreement is hereby amended to add a new
        subsection (d), as follows:

                "(d) If, following termination of Employee's employment with

                   AMENDMENT NO. 1 TO THE EMPLOYMENT AGREEMENT


        THIS AMENDMENT NO. 1 TO THE AGREEMENT made as of December 26, 1992,
between STORAGE DIMENSIONS, INC., a Delaware corporation (the "Employer"), and
Robert Bylin (the "Employee"), is made as of this __ day of March, 1998.


                                   WITNESSETH:

        WHEREAS, Employer and Employee entered into an Employment Agreement on
December 22, 1992 (the "Agreement") by which Employee currently serves as Vice
President and Chief Financial Officer of Employer;

        WHEREAS, Employer and Employee now desire to amend the Agreement to
change the benefits payable to Employee in the event of termination of
Employee's employment or consulting relationship with Employer.

        NOW, THEREFORE, in consideration of the premises, the covenants
contained herein, and other good and valuable consideration, the Employer and
the Employee hereby amend the Agreement as follows:

        1. Amendment to Section 4.1(b) of the Agreement. Section 4.1(b) of the
Agreement is hereby amended to read in its entirety as follows:

               "(b) In addition, for so long as Employee continues to be engaged
        by Employer or any subsidiary thereof as an employee or a consultant and
        for the period during which Employer or any subsidiary thereof makes
        severance payments to Employee pursuant to Section 5.3(a), Employee will
        not, without the express written consent of Employer, directly or
        indirectly engage, participate or invest in or assist, as owner, part
        owner, shareholder, partner, director, officer, trustee, employee, agent
        or consultant, or in any other capacity, any business organization other
        than Employer whose activities or products are competitive with
        activities or products of Employer or any subsidiary thereof in which
        activities Employee shall have participated or as to which products
        Employee shall have had responsibility either in their development,
        marketing or otherwise, provided that Employee may make passive
        investments in a competitive enterprise the shares of which are publicly
        traded if Employee's investment constitutes less than 5% of the
        outstanding shares of such enterprise. The foregoing agreement not to
        compete shall apply in any and all cities and counties of each state of
        the United States of America in which the activities of Employer or any
        subsidiary thereof shall have been conducted, or the products of any of
        them sold, on or before the date upon which Employee's employment by
        Employer or any subsidiary thereof ceases."

        which is a subsidiary of the foregoing during the period in which the
        noncompetition agreement set forth in Section 4.1 is in effect."

        3. Amendment to Section 5.1 of the Agreement. Section 5.1 of the
Agreement is hereby amended to add the following language to the end thereof:

        "or until terminated pursuant to Section 5.2 of this Agreement, as

                (a) Section 5.2(b) is hereby amended to delete the phrase

               "Any termination of Employee's status as an employee or

        consultant) following a "Change in Control", whether at Employer's or
        Employee's option (other than a termination by Employer under Section
        5.2(c)), shall be deemed to be a termination by Employer pursuant to
        this Section 5.2(b) and Employer shall make severance payments as
        provided in Section 5.3(a). "Change of Control" shall mean any merger or

        transaction pursuant to which the stockholders of Employer before such
        transaction no longer hold at least 50% of the voting securities of the
        Employer after such transaction. In no event, however, shall the change
        in Employee's title contemplated under Section 2.1 of this Agreement, as
        amended, or any commensurate change in Employee's duties be a
        termination pursuant to this Section 5.2(b) or trigger Employer's
        obligation to make severance payments under Section 5.3(a)."

                (c) Section 5.2 of the Agreement is hereby amended to add a new
        subsection (d), as follows:

                "(d) If, following termination of Employee's employment with
        Employer by either Employee or Employer, the parties mutually determine

        termination one hundred percent (100%) of Employee's regular weekly base
        salary in effect on the date of termination of Employee's employment or

        withholding), such amount to be payable in equal installments on the

        date next following the date of such termination. In the event of such
        termination, the stock option referred to in Section 3.2(b), and any
        subsequently granted stock options, shall be exercisable only to the
        extent vested as of such termination in accordance with their terms;
        provided, however, that such options shall be amended by the Company in
        order to provide that they may be exercised, to the extent exercisable
        at the time of such termination, for a period of one year from the date
        of such termination (provided, however, that the extension of time in
        which the options may be exercised shall only be triggered if the
        termination is at the Employer's option or is mutually agreed to by
        Employer and Employee)."

        6. Amendment of Section 6.2 of the Agreement. Section 6.2 shall be
amended to add the following as a new paragraph immediately following the
paragraph which begins "To Employer":

        "provided, however, that notwithstanding the foregoing, following the
        Closing Date, any notice to be delivered hereunder to Employer shall
        instead be sent to the following address:
