Dear Shareholder of The Santa Cruz Operation:

     We invite you to attend a special meeting of the shareholders of The Santa
Cruz Operation, Inc. ("SCO") to be held at           at      a.m. local time, on
            , 2000. At the special meeting, we will ask you to consider a
proposal to approve and adopt the agreement and plan of reorganization that we
entered into with Caldera Systems, Inc. and Caldera, Inc. on August 1, 2000 and
amended on September 13, 2000, and a proposal to change our corporate name to
"Tarantella, Inc."

     Under the reorganization agreement, Caldera Systems, Inc. will acquire the
assets of our server and our professional services groups. A new company,
Caldera, Inc., will be formed, combining the assets of Caldera Systems with the
assets acquired from SCO. After the combination is completed, we will continue
to operate our Tarantella business, and accordingly, have decided to change our
corporate name. Under the proposed transaction, SCO and its employees who join
Caldera, Inc. will receive approximately 28.6% of Caldera, Inc., or 18.4 million
shares of Caldera, Inc. common stock (including approximately two million shares
reserved for employee options assumed or replaced by Caldera, Inc. for options
currently held by SCO employees joining Caldera, Inc.), and SCO will receive $7
million in cash.

     We are very excited about the opportunities we envision for the combined
company and for our ongoing operations. However, we cannot complete the
combination unless all of the conditions to the closing are satisfied, including
the approval and adoption of the reorganization agreement by holders of a
majority of SCO voting stock.

     Douglas Michels, our President and Chief Executive Officer and largest
shareholder with beneficial ownership of approximately 11.3% of the outstanding
SCO common stock as of August 15, 2000, has entered into a voting agreement with
Caldera Systems to vote all of his SCO common stock in favor of approving and
adopting the agreement and plan of reorganization and to appoint representatives
of Caldera Systems as proxies to vote his common stock of The Santa Cruz
Operation at the meeting.

     Your vote is very important. Whether or not you plan to attend the special
meeting, you should complete, sign, date and promptly return the enclosed proxy
card in the enclosed envelope or complete the your proxy via telephone or the
Internet to ensure that your shares will be represented at the meeting. If you
attend the meeting, you may vote in person if you wish, even though you have
previously returned your proxy.

     AFTER CAREFUL CONSIDERATION, OUR BOARD OF DIRECTORS HAS UNANIMOUSLY
APPROVED THE COMBINATION AND CONCLUDED THAT IT IS IN THE BEST INTERESTS OF THE
SANTA CRUZ OPERATION AND YOU, OUR SHAREHOLDERS, AND UNANIMOUSLY RECOMMENDS THAT

                           FREQUENTLY ASKED QUESTIONS

     This document contains a great deal of important information. Your
individual circumstances will determine which aspects of that information apply
to you, and the decisions you will make in connection with this document. For
these reasons, this series of frequently asked questions will not answer all of
the questions you may have. Rather they are designed to give you a clearer
understanding of the choices you will make.

INTRODUCTORY QUESTIONS

Q:  WHAT IS THE COMBINATION BEING PROPOSED?

A:  The transaction being proposed is as follows:

     - a new company, Caldera, Inc., or New Caldera, has been formed to
       facilitate the proposed combination.

     - Caldera Systems, Inc., or Caldera, will merge to become a wholly-owned
       subsidiary of New Caldera.

     - The Santa Cruz Operation, Inc., or SCO, will contribute the assets of its
       server and professional services groups to New Caldera.

Q:  WHAT IS "NEW CALDERA"?

A:  New Caldera is what we call the combined company after the combination in
    this joint proxy statement/prospectus. The entity will be called Caldera,
    Inc., and it will become the parent company of Caldera Systems. New Caldera
    will also directly own the server and professional services groups
    contributed by SCO.

QUESTIONS FOR CALDERA STOCKHOLDERS

Q:  WHAT WILL I RECEIVE IN THE COMBINATION?

A:  If we complete the combination, each share of Caldera common stock you own
    will automatically be converted into one share of New Caldera common stock.
    Your current Caldera stock certificate will then no longer represent shares
    of Caldera, and will instead represent shares of New Caldera. The Caldera
    stockholders and stock option holders will own approximately 71.4% of New
    Caldera on a fully diluted basis.

Q:  WHAT WILL I GIVE UP IN THE COMBINATION?

A:  You will give up your stock ownership in Caldera. However, you will not give
    up your stock certificate or make any payment because your old stock
    certificate will represent your interest in New Caldera. PLEASE DO NOT SEND
    YOUR CALDERA STOCK CERTIFICATES.

Q:  WHAT TAXES WILL I OWE AS A RESULT OF THE COMBINATION?

A:  None. The combination will be tax-free to Caldera and its stockholders for
    U.S. federal income tax purposes. See page 52.

Q:  ARE THERE RISKS I SHOULD CONSIDER IN DECIDING WHETHER TO VOTE FOR THE
    COMBINATION?

A:  Yes. In evaluating the combination, you should keep in mind that if the
    combination occurs, you will be subject to the risks related to the business
    of New Caldera. You should, therefore, consider the factors discussed in the
    section entitled "Risk Factors" beginning on page 14.

Q:  DOES THE BOARD OF DIRECTORS OF CALDERA RECOMMEND APPROVAL OF THE MERGER
    AGREEMENT AND THE REORGANIZATION?

A:  Yes. After careful consideration, the board of directors of Caldera
    unanimously recommends that its stockholders vote in favor of the approval
    and adoption of the reorganization agreement and the proposed combination.

Q:  WHAT RIGHTS DO I HAVE TO DISSENT FROM THE COMBINATION?

A:  None. If the reorganization agreement is approved, you will not, under
    Delaware General Corporation Law, have the right to dissent from the
    approval.

QUESTIONS FOR SCO SHAREHOLDERS

Q:  WHAT WILL SCO RECEIVE IN THE COMBINATION?

A:  In exchange for the assets of SCO's server and professional services groups,
    SCO and its employees who join Caldera, Inc. will receive approximately
    28.6% of Caldera, Inc., or

                                       iii
<PAGE>   10

    18.4 million shares of Caldera, Inc. common stock (including approximately
    two million shares reserved for employee options assumed or replaced by
    Caldera, Inc. for options currently held by SCO employees joining Caldera,
    Inc.), and SCO will receive $7 million in cash.

Q:  WILL THE CURRENT SHAREHOLDERS OF SCO BE ISSUED SHARES OF NEW CALDERA WHEN
    THE COMBINATION CLOSES?

A:  No. The New Caldera shares received by SCO in the combination will become an
    asset of SCO. There is no current intention to distribute New Caldera stock
    directly to SCO shareholders. SCO intends to hold the New Caldera shares
    because of the adverse tax impact of distributing the stock. There are also
    distribution limitations that are part of the reorganization agreement with
    Caldera.

Q:  WHAT IS THE EFFECT ON SCO IF THE COMBINATION TAKES PLACE?

A:  SCO will continue to operate its Tarantella division and hold the assets of
    that division, the SCO OpenServer intellectual property and its future
    revenue stream, and the assets of our investment holdings, including shares
    of New Caldera common stock received in the combination. SCO's headquarters
    will remain in Santa Cruz, California and there will be approximately 230
    employees worldwide.

Q:  DOES THE BOARD OF DIRECTORS OF SCO RECOMMEND VOTING IN FAVOR OF THE PROPOSED
    COMBINATION?

A:  Yes. After careful consideration, the board of directors of SCO unanimously
    recommends that its shareholders vote in favor of the approval and adoption
    of the reorganization agreement and the proposed reorganization.

Q:  ARE THERE RISKS I SHOULD CONSIDER IN DECIDING WHETHER TO VOTE FOR THE
    COMBINATION?

A:  Yes. In evaluating the combination, you should keep in mind that if the
    combination occurs, you will be subject to the risks related to the business
    of Caldera as well as risks that relate to SCO's business. You should,
    therefore, consider the factors discussed in the section entitled "Risk
    Factors" beginning on page 14.

QUESTIONS FOR SCO OPTION HOLDERS WHO BECOME NEW CALDERA EMPLOYEES

Q:  WHAT WILL BECOME OF THE OPTIONS I CURRENTLY HOLD FOR SCO COMMON STOCK?

A:  Assuming you are offered and accept employment with New Caldera, you will be
    entitled to select between two alternatives with respect to the treatment of
    each of your SCO option grants. Under the first alternative, you may elect
    to have some or all of your option grants assumed by New Caldera. Under the
    second alternative, you may elect to have some or all your existing SCO
    option grants cancelled and replaced with new options to purchase New
    Caldera common stock.

Q:  WHAT WILL HAPPEN TO MY SCO STOCK OPTIONS IF I CHOOSE THE "ASSUMPTION"
    ALTERNATIVE?

A:  SCO stock option grants assumed by New Caldera will continue to have their
    original terms (including vesting schedule and termination provisions), and
    be subject to their original conditions, that were applicable to the option
    immediately prior to the effective time, except that:

    - each SCO stock option will become exercisable for shares of New Caldera
      common stock,

    - the number of shares of New Caldera common stock issuable upon the
      exercise of any given SCO option will be one half of the number of shares
      of SCO common stock subject to the option immediately prior to the
      effective time, rounded down to the nearest whole number,

    - the per share exercise price of any given option will be two times the
      exercise price of the option immediately prior to the effective time,
      rounded up to the nearest whole cent, and

    - the option for shares of New Caldera may not qualify as an incentive stock
      option even though the SCO option may have.

    For an illustration of how this alternative works, please see page 69.
                                       iv
<PAGE>   11

Q:  WHAT WILL HAPPEN TO MY SCO STOCK OPTIONS IF I CHOOSE THE "REPLACEMENT"
    ALTERNATIVE?

A:  Under the "replacement" alternative:

    - each SCO stock option will be exchanged for an option exercisable for
      shares of New Caldera common stock,

    - the number of shares of New Caldera common stock issuable upon the
      exercise of the replacement option will be one half of the number of
      shares of SCO common stock under the cancelled option immediately prior to
      the effective time, rounded down to the nearest whole number,

    - the per share exercise price of an option will be the fair market value of
      New Caldera common stock immediately after the closing of the combination,
      and

    - the vesting schedule of the New Caldera options will be determined as
      follows: (i) the number of vested shares of common stock under the New
      Caldera replacement options will equal the number of vested shares of
      common stock under the SCO option grant immediately prior to the effective
      time multiplied by 0.25 and (ii) the remaining unvested replacement
      options will vest over a period of months determined by the following
      equation: 48 months less one half of the number of months vested under the
      SCO option grant immediately prior to the effective time.

    - the replacement option grants will qualify as incentive stock options to
      the maximum extent permissible under the federal tax laws.

    For an illustration of how this alternative works, please see page 69.

Q:  WHAT WILL BE THE TAX CONSEQUENCES OF THESE OPTION ALTERNATIVES?

A:  There will be no immediate tax consequences from either alternative.
    However, under the assumption alternative, if you had an incentive stock
    option while at SCO, you may have a non-qualified option after the
    assumption.

Q:  WHAT WILL HAPPEN IF I DO NOT ELECT TO HAVE MY SCO OPTIONS ASSUMED OR
    REPLACED?

A:  If you do not elect to participate in the employee stock option assumption
    and replacement, the unvested portion of your SCO stock options will be
    canceled as of the date the combination is completed. You will have only 30
    days after the completion of the combination to exercise the vested portion
    of your SCO stock options.

Q:  WHAT DO I NEED TO DO NOW?

A:  Your options will not be assumed or replaced automatically when you become
    an employee of New Caldera. If you wish to exchange your SCO stock options
    assumed by New Caldera or cancelled and replaced with New Caldera stock
    options, please follow the instructions on page 70. IF YOU DO NOT FOLLOW
    THESE DIRECTIONS, YOUR OPTIONS WILL EXPIRE.

OTHER QUESTIONS FOR ALL STOCKHOLDERS/SHAREHOLDERS

Q:  WHAT DO I NEED TO DO NOW?

A:  We urge you to read this joint proxy statement/prospectus, including its
    appendices, carefully, and to consider how the merger will affect you as a
    shareholder. You may also want to review the documents referenced under
    "Where You Can Find More Information" on page 27.

Q:  WHEN DO YOU EXPECT THE COMBINATION TO BE COMPLETED?

A:  We are working toward completing the combination as quickly as possible. We
    hope to complete it during the fourth calendar quarter of 2000.

Q:  WHAT DO I NEED TO DO NOW TO VOTE?

A:  Just indicate on your proxy card how you want to vote, and sign and mail it
    in the enclosed return envelope as soon as possible, so that your shares may
    be represented at your meeting. If you sign and send in your proxy and do
    not indicate how you want to vote, your proxy will be counted as a vote in
    favor of the combination. You may instead choose to attend your meeting and
    vote your shares in person.

                                        v
<PAGE>   12

Q:  MAY I CHANGE MY VOTE AFTER I HAVE MAILED IN MY SIGNED PROXY CARD?

A:  You may change your vote at any time before the vote takes place at the
    Caldera or SCO special meeting, respectively. To change your vote, you may
    either submit a later dated proxy card or send a written notice stating that
    you would like to revoke your proxy. In addition, you may attend the special
    meeting and vote in person. However, if you elect to vote in person at the
    Caldera or SCO special meeting, respectively, and your shares are held by a
    broker, bank or other nominee, you must bring to the special meeting a legal
    proxy from the broker, banker or other nominee authorizing you to vote the
    shares.

Q:  IF MY SHARES OF STOCK ARE HELD IN "STREET NAME" BY MY BROKER, WILL MY BROKER
    VOTE MY SHARES FOR ME?

A:  Your broker will vote your shares only if you provide instructions on how to
    vote. Without instructions, your shares will not be voted. You should
    instruct your broker to vote your shares, following the directions provided
    by your broker. See pages 29 and 31.

Q:  SHOULD I SEND IN MY STOCK CERTIFICATES NOW?

A:  No. Neither Caldera stockholders nor SCO shareholders will exchange their
    stock certificates.

Q:  WHERE CAN I FIND MORE INFORMATION ABOUT CALDERA AND SCO?

A:  Both Caldera and SCO file reports, proxy and information statements and
    other information with the Securities and Exchange Commission. You may read
    and copy this information at the SEC's public reference facilities. Please
    call the SEC at 1-800-SEC-0330 for information about these facilities. This
    information is also available at the Internet site the SEC maintains at
    www.sec.gov. See "Where You Can Find More Information" beginning on page 27
    of this document.

Q:  WHOM AT CALDERA OR SCO SHOULD I CONTACT IF I HAVE ANY QUESTIONS ABOUT THE
    COMBINATION?

A:  You should contact either Kathy Allred of Caldera by telephone at
    801-765-4999 or by e-mail at [email protected], or Lynn Schroeder of SCO
    by telephone at 831-427-7399 or by e-mail at [email protected], with any
    questions about the combination.

     SCO provides server-based software for networked business computing. SCO
also provides UNIX server operating systems and network computing software that
enables clients of all kinds -- including, personal computers, graphical
terminals, network computers, and other devices -- to have webtop access to
business-critical applications running on servers of all kinds.

THE COMBINATION

     Caldera, New Caldera and SCO have entered into a reorganization agreement
that provides for the following transactions:

     - New Caldera will purchase the server and professional services groups
       from SCO by issuing to SCO and its employees who join New Caldera
       approximately 18.4 million shares, or approximately 28.6% on a fully
       diluted basis, of New Caldera's common stock (including approximately 2.0
       million shares reserved for employee options assumed or replaced by New
       Caldera for options currently held by SCO employees joining New Caldera)
       and paying $7 million cash to SCO.

     - Caldera will merge with a subsidiary of New Caldera and as a result will
       become a wholly-owned subsidiary of New Caldera. Stockholders of Caldera
       will become stockholders of New Caldera following the merger, and each
       share of Caldera common stock will be exchanged for one share of New
       Caldera common stock.

     We urge you to read carefully the reorganization agreement in its entirety.
The reorganization agreement is attached as Appendix A to this joint proxy
statement/prospectus.

NO SOLICITATION BY SCO (SEE PAGE 61)

     Subject to the applicable fiduciary duties to its shareholders, the SCO
board of directors, SCO has agreed that neither it nor any of its subsidiaries
will do any of the following:

     - solicit, initiate or encourage the submission of any alternative
       proposal;

     - engage in discussions or negotiations concerning, or provide any
       non-public information to a third party regarding an alternative
       proposal;

       facilitate any inquiries or the making of any proposal that constitutes
       or would reasonably be expected to lead to any alternative proposal;

       agreement with respect to any alternative transactions; or

     - make or authorize any statement, recommendation or solicitation in
       support of any alternative transactions.

     SCO has also agreed to cause each of its officers, directors, employees,
financial advisors, representatives and agents not to take any of these actions.

TERMINATION OF THE REORGANIZATION AGREEMENT (SEE PAGE 64)

     Caldera and SCO can mutually agree to terminate the reorganization
agreement without completing the transaction, and either Caldera or SCO can
terminate the reorganization agreement if:

     - the other party materially breaches any representation, warranty,
       covenant or agreement in the reorganization agreement and fails to cure
       the breach within 30 days of receiving notice of the breach;

     - the transactions contemplated by the reorganization agreement are not

<PAGE>   15

     - the board of the other party modifies or withdraws its approval or
       recommendation of the combination.

     In addition, Caldera may terminate the reorganization agreement if the
board of SCO recommends any SCO alternative proposal.

TERMINATION FEES AND EXPENSE

     SCO must pay Caldera a termination fee equal to 3 1/2% of the value of 28%
of Caldera common stock if the reorganization agreement is terminated and the
SCO board has changed its recommendation.

     - SCO has violated its non-solicitation obligations; and

     - within 6 months an agreement is entered into for an alternative proposal
       or within 12 months an alternative proposal is consummated.

     Caldera must pay SCO the termination fee if the reorganization agreement is
terminated because the Caldera board has changed its recommendation.

OPINIONS OF FINANCIAL ADVISORS (SEE PAGES 40 AND 45)

     In deciding to approve the combination, our boards of directors considered
the opinions of each of our financial advisors.

     Caldera received an opinion from its financial advisor, Broadview
International, LLC, that as of August 1, 2000, the consideration to be paid for
the server and professional services groups was fair to Caldera from a financial
point of view. Caldera has agreed to pay Broadview fees totaling approximately
$2.0 million. Caldera paid $300,000 upon delivery of the fairness opinion and
the remainder of the fee is contingent upon consummation of the combination.
Broadview and Caldera believe that these fees are customary in transactions of
this nature.

     SCO received an opinion from its financial advisor, Chase H&Q, that as of
August 1, 2000 the consideration to be received by SCO from New Caldera was fair
to SCO from a financial point of view. SCO has agreed to pay Chase H&Q fees
totaling approximately $2.1 million. SCO has paid a $25,000 agreement fee and a
$750,000 retainer. The remainder of the fee is contingent upon consummation of
the combination. SCO and Chase H&Q believe that these fees are customary in
transactions of this nature.

     WE ENCOURAGE YOU TO READ THESE OPINIONS CAREFULLY. THEY ARE ATTACHED AS
APPENDICES B AND C.

INTERESTS OF PERSONS IN THE COMBINATION (SEE PAGE 56)

     Certain persons and entities have interests in the combination which may
differ from yours because of their status as a director, nominee for director or
executive officer of Caldera, SCO or New Caldera. For instance:

     - Certain officers of SCO, including David McCrabb, Jack Moyer and James
       Wilt will become executive officers of New Caldera;

     - SCO will provide change-of-control benefits to its current executive
       officers;

     - SCO will have the right to nominate 2 directors of the New Caldera board;

     - Doug Michels and an individual to be determined by SCO and approved by
       Caldera will be directors of New Caldera;

                                        3
<PAGE>   16

     - SCO has granted additional "stay-put" options to certain executive
       officers to encourage those individuals to remain with SCO following the
       combination; and

     - Each person who becomes an executive officer or key employee of New
       Caldera will sign an employment agreement with New Caldera that provides
       for terms of employment and severance benefits, among other things.

DISSENTERS' RIGHTS (SEE PAGES 30 AND 32)

     The Caldera stockholders do not have dissenters' rights in connection with
the combination.

     If holders of 5% or more of the outstanding shares of SCO common stock
entitled to vote at the SCO special meeting vote against the reorganization
agreement and comply with certain other procedures specified in Chapter 13 of
the California Corporations Code, SCO shareholders of record who take such
actions will be entitled to exercise dissenters' rights. In accordance with the
provisions of the California Corporations Code, dissenting SCO shareholders will
have the right to be paid in cash the fair market value of their shares of SCO
common stock, determined as of the day before the first announcement of the
combination, and excluding any appreciation or depreciation as a result of the
combination. A copy of Chapter 13 of the California Corporations Code is
attached to this document as Appendix N.

ACCOUNTING TREATMENT OF THE COMBINATION (SEE PAGE 53)

     We expect the combination will be accounted for as a purchase, which means
that we will incur substantial non-cash charges to earnings of approximately
$7.7 million per quarter over the next three years and approximately $6.0
million per quarter for the subsequent two years related to the amortization of
goodwill and other intangible assets.

     We expect that SCO will recognize a gain on the combination equivalent to
approximately 70.5% of the difference between the fair value of the New Caldera
shares received and its carrying amount of the server and professional services
groups, which will be approximately $79.8 million. After the combination closes,
SCO will report approximately 29.5% of the operations of New Caldera under the
equity method of accounting, after certain adjustments, in its financial
statements.

OWNERSHIP OF NEW CALDERA FOLLOWING THE COMBINATION

     The following table illustrates the approximate percentage ownership of New
Caldera if the combination is completed. The percentages reflect the estimated
ownership of all common stock, assuming the exercise of all stock options of New
Caldera, and are calculated based on shares outstanding as of September 1, 2000.

DIRECTORS AND EXECUTIVE OFFICERS OF NEW CALDERA FOLLOWING THE COMBINATION (SEE
PAGE 113)

     If we complete the combination, the board of directors of New Caldera will
initially consist of all of the current board members of Caldera as well as Doug
Michels and an individual to be determined by SCO and approved by Caldera.

     The executive officers of New Caldera will consist of all of the current
executive officers of Caldera, as well as David McCrabb, Jim Wilt and Jack
Moyer.

LISTING OF NEW CALDERA COMMON STOCK (SEE PAGE 51)

     We expect that the shares of New Caldera common stock to be issued in
connection with the combination will be approved for listing on the Nasdaq
National Market, subject to official notice of issuance. The trading symbol for
the New Caldera common stock will be "CALD," the symbol currently used for
Caldera.

CONDITIONS TO COMPLETION OF THE COMBINATION (SEE PAGE 59)

     The respective obligations of the parties to complete the combination are
subject to approval of the reorganization agreement and combination by Caldera's
stockholders and SCO's shareholders, as well as the prior satisfaction or waiver
(if permitted by applicable law) of conditions specified in the reorganization
agreement. The following conditions, among others, must be satisfied or waived
before the combination can be completed:

     - the combination shall have been approved and adopted by both the Caldera
       stockholders and the SCO shareholders;

     - the board of directors of New Caldera shall have appointed Mr. Michels
       and an individual to be determined by SCO and approved by Caldera to the
       board of directors of New Caldera;

     - the relevant parties shall have entered into the stockholder agreement,
       the escrow agreement, sales representation and support agreement, and the
       voting agreements;

     - the New Caldera common stock to be issued in the combination shall have
       been approved for quotation on the Nasdaq National Market, subject to
       notice of issuance;

     - the representations and warranties of the other party contained in the
       reorganization agreement shall be accurate except for representations and
       warranties that address matters as of a particular date and where the
       breaches have not resulted in a material adverse effect;

     - the parties shall have materially complied with the covenants contained
       in the reorganization agreement; and

     - each of Caldera and SCO shall have received an opinion of their counsel
       as to the tax consequences of the combination.

UNITED STATES FEDERAL INCOME TAX CONSEQUENCES OF THE COMBINATION (SEE PAGE 52)

     The combination has been structured as a tax-free transaction described in
Section 351 of the Internal Revenue Code and, as to Caldera, a "reorganization"
under Section 368 of the Internal Revenue Code for United States federal income
tax purposes. If the combination qualifies as a tax-free transaction and, as to
Caldera, as a "reorganization" under Section 368 of the Internal Revenue Code,
neither Caldera's stockholders generally or SCO will recognize gain or loss for
United States federal income tax purposes in the combination (except to the
extent of cash received by SCO in the combination). It is a condition to the
completion of the combination that each of Caldera and SCO receive an opinion of
their counsel as to the tax consequences of the combination.

                SUMMARY OF THE EMPLOYEE STOCK OPTION ASSUMPTION
                             AND REPLACEMENT OFFER

     Employees of the server and professional services groups who become
employees of New Caldera have the opportunity to either (i) have their SCO stock
options cancelled and replaced with options to purchase shares of New Caldera
common stock at an exercise price equal to the fair market value of New Caldera
common stock immediately after the closing or (ii) have their SCO options
assumed by New Caldera for shares of New Caldera common stock at an exercise
price equal to twice the exercise price of the SCO stock options. See page 69.
Regardless of the alternative chosen, the number of shares of New Caldera common
stock issuable upon the exercise of any given SCO option will be one half of the
number of shares of SCO common stock subject to the option immediately prior to
the effective time.

OUR REASONS FOR THE EMPLOYEE STOCK OPTION ASSUMPTION AND REPLACEMENT OFFER

     Caldera and SCO negotiated the employee stock option assumption and
replacement offer to enable the server and professional services group employees
to have similar incentives for Caldera success to those the stockholders of New
Caldera have. SCO's stock option plan will continue to govern the option grants
of employees of SCO who do not become employees of New Caldera and remain with
SCO. If you become an employee of New Caldera and do not choose to have your SCO
options assumed or replaced, your options will terminate 30 days after the
closing of the combination pursuant to SCO's stock option plan.

PROCEDURES TO EFFECT ASSUMPTION OR REPLACEMENT (SEE PAGE 70)

     Server and professional services group employees who hold SCO stock options
should send the enclosed notice of election, by mail postmarked on or before
            , 2000, to:

         The Santa Cruz Operation, Inc.
         425 Encinal Street
         Santa Cruz, California 95061
         Attn: Steve Sabbath

     IF YOU ARE OFFERED AND ACCEPT EMPLOYMENT WITH NEW CALDERA AND DO NOT
COMPLETE APPENDIX M, THE NOTICE OF ELECTION TO PARTICIPATE IN THE ASSUMPTION AND
REPLACEMENT OFFER, THE UNVESTED PORTION OF YOUR SCO STOCK OPTIONS WILL BE
CANCELED AS OF THE DATE THE COMBINATION IS COMPLETED. YOU WILL HAVE ONLY 30 DAYS
AFTER THE COMBINATION IS COMPLETED TO EXERCISE THE VESTED PORTION OF YOUR SCO
OPTIONS.

THE TAX STATUS OF SCO OPTIONS WILL DEPEND ON THE ALTERNATIVE CHOSEN BY AN
EMPLOYEE (SEE PAGE 52)

     There will be no immediate tax consequences from either alternative. Under
the replacement alternative, the new option granted to an employee will be an
incentive stock option to the maximum extent permissible under the federal tax
laws. Under the assumption alternative, if an employee had an incentive stock
option while at SCO, an employee may have a non-qualified option after the
assumption.

VESTING SCHEDULE OF OPTIONS MAY CHANGE (SEE PAGE 69)

     Under the assumption alternative, your vesting schedule will not be
changed. Under the replacement alternate, your vesting schedule will be changed
as described under "Replacement Alternative", page 69.

                                  RISK FACTORS

     In evaluating the proposals to be voted on at your meeting please carefully
consider the information presented throughout this document, and in particular
the following risk factors. Some of these risk factors relate directly to the
combination described in this document, while others relate to the businesses of
New Caldera, Caldera and the server and professional services group.

RISKS RELATING TO THE COMBINATION

New Caldera might fail to successfully integrate the businesses of Caldera and
the server and professional services groups

     Product line integration will be difficult. If New Caldera completes the
combination of the server and professional services groups with Caldera's Linux
business, which is not assured, New Caldera will need to integrate two
independent businesses. One key issue will be the integration of Caldera's Linux
product offerings and SCO's Unixware. This product line integration will involve
consolidation of products with duplicative functionality, coordination of
research and development activities, and convergence of the technologies
supporting the various products.

     Other business integration issues could arise. Other problems inherent in
integrating the businesses of Caldera and the server and professional services
groups include:

     - maintaining brand recognition for key products of the server business,
       such as Unixware while migrating customer identification of the brands to
       New Caldera;

     - resolving channel conflicts that may arise between third party
       distributor and electronic solution provider channels of Caldera and the
       channels of the server business;

     - coordinating, integrating and streamlining geographically dispersed
       operations; and

     - coping with customers' uncertainty about continued support for
       duplicative New Caldera products.

     Management and employee integration issues could arise. Potential
management and employee integration problems include:

     - resolving differences between the corporate cultures of Caldera and the
       server and professional services groups;

     - employee turnover; and

     - integrating the management teams of both companies successfully.

     The integration will be expensive. In addition, management's focus on the
combination is likely to interrupt the current business activities of Caldera
and the server and professional services groups. Any of these risks could harm
New Caldera's revenue and results of operations.

     Operational issues could arise. Potential operational integration problems
include conflict between each of Caldera's and SCO's:

     - management information systems;

     - telephone systems; and

     - customer data.

Certain individuals have interests that are different from or in addition to
yours, which could influence them to support the combination.

     Members of the boards of directors and management of Caldera and SCO, and
certain officers of SCO will receive benefits from the combination in addition
to those which you will receive. Because of

                                       14
<PAGE>   27

these benefits, these persons may be influenced to vote in favor of or to
recommend the combination. These interests include:

     - The current executive officers and directors of Caldera will become
       executive officers and directors of New Caldera;

     - David McCrabb, Jack Moyer and Jim Wilt are executive officers of SCO or
       employees of the server and professional services groups, and will become
       executive officers of New Caldera;

     - Each of the SCO executive officers and employees of the server and
       professional services groups who will become executive officers of New
       Caldera, and other key employees of the server and professional services
       groups, will sign employment agreements with New Caldera that provide for
       terms of employment and severance benefits, among other things;

     - SCO will provide change-of-control benefits to its current executive
       officers;

     - SCO has granted additional "stay-put" options to certain executive
       officers to encourage those individuals to remain with SCO following the
       combination; and

     - SCO will have the right to nominate two members of the New Caldera board
       of directors, who will initially be Doug Michels and an individual to be
       named by SCO and approved by Caldera.

New Caldera will incur significant accounting charges in connection with the
combination that will impact its operating results immediately and in the future

     The significant costs of integration associated with the combination
increases the risk that New Caldera will not realize the anticipated benefits.
Because New Caldera will account for the combination as a purchase, it expects
to incur a non-cash charge of approximately $3.2 million at the date of the
combination, related to the write-off of in-process research and development.
New Caldera also will record goodwill and other intangible assets of
approximately $140.6 million. This amount will be amortized over periods ranging
from three to five years, and will result in charges to operations of
approximately $7.7 million per quarter for the first three years and
approximately $6.0 million per quarter for the subsequent two years. Please see
"New Caldera Unaudited Pro Forma Condensed Combined Financial Statements" on
page P-1.

RISKS RELATING TO NEW CALDERA AFTER THE COMBINATION

New Caldera may not be profitable

     Caldera has not been profitable. The server and professional services
groups have not been profitable and their revenue has been declining. If New
Caldera's revenue declines or grows at a slower rate than anticipated or if New
Caldera is unable to efficiently reduce operating expenses, New Caldera may not
achieve or sustain profitability or generate positive cash flow. In this case,
the value of an investment in New Caldera could be reduced.

     For the fiscal year ended October 31, 1999, and the nine-months ended July
31, 2000, Caldera incurred net losses attributable to common stockholders of
approximately $9.4 million and $32.3 million, respectively. As of July 31, 2000,
Caldera had incurred total net losses of $49.6 million since its inception in
1994.

     For the fiscal year ended September 30, 1999, and the nine months ended
June 30, 2000, the server and professional services groups incurred net losses
of approximately $46.6 million and $44.4 million, respectively. On a pro forma
basis, the combined operations of Caldera and the server and professional
services groups would have incurred net losses attributable to common
stockholders of approximately $99.5 million and $86.8 million for the nine
months ended July 31, 2000 and the fiscal year ended October 31, 1999,
respectively.

                                       15
<PAGE>   28

New Caldera's integrated product offerings may not be accepted

     New Caldera will face risks and uncertainties relating to its ability to
successfully implement its strategy. New Caldera's business model is based on an
expectation that it can create and develop demand for combined Linux and
Unix-based servicers and applications. There is no current market for combined
Linux and Unix-based servers and applications. At present Microsoft and other
non-Linux operating systems are favored by the business community.

     In order for New Caldera's product offering to be accepted New Caldera
must:

     - broaden awareness of the New Caldera brand;

     - maintain its current, and develop new, strategic relationships with
       technology partners and solution providers;

     - continue to develop and upgrade product offerings tailored for business;
       and

     - respond effectively to competitive pressures.

     If New Caldera is unable to execute its strategy, New Caldera may not be
successful.

New Caldera will face many difficulties in managing a larger company

     In deciding whether to approve and adopt the reorganization agreement and
the combination, you should bear in mind that the larger combined company will
create new challenges for Caldera's existing management. If New Caldera fails to
meet these challenges, the value of an investment in New Caldera may decline.
After the combination, New Caldera will have a workforce approximately four
times the size of the Caldera workforce prior to the combination. Key personnel
have little experience managing this type of growth. This growth is likely to
strain New Caldera's management control systems and resources, including
decision support, accounting and management information systems. New Caldera
will need to continue to improve its financial and management controls and its
reporting systems and procedures to manage its employees and to obtain
additional facilities. If New Caldera does not succeed in these efforts, it
could reduce New Caldera's revenue and the value of an investment.

New Caldera will need to retain its personnel, which will be difficult

     As a result of the combination, New Caldera will need to retain the
personnel of both Caldera and the server and professional services groups.
Competition for qualified professionals in the software industry is intense, and
New Caldera may be unable to retain sufficient professionals to operate the
combined business. Departures of existing personnel could be disruptive to its
business and can result in the departure of other employees.

     The loss or departure of any of New Caldera's officers or key employees
could harm New Caldera's ability to implement its business plan and could lower
its revenue. New Caldera's future success depends to a significant extent on the
continued service and coordination of its management team, particularly Ransom
H. Love, New Caldera's Chief Executive Officer. New Caldera does not maintain
key person insurance for any member of its management team.

     Even though New Caldera intends to enter into employment agreements with
key management personnel, these agreements cannot prevent the departure of those
employees.

New Caldera faces intense competition

     In considering whether to approve this combination, Caldera stockholders
and SCO shareholders should bear in mind that New Caldera will have new
competitors. New Caldera's principal competitors include:

     - Microsoft;

     - Cygnus Solutions;

                                       16
<PAGE>   29

     - VA Linux;

     - Wind River Systems;

     - Sun Microsystems;

     - Corel;

     - MacMillan;

     - Red Hat;

     - SuSE;

     - AT&T;

     - Compaq;

     - Hewlett-Packard;

     - IBM;

     - Novell; and

     - Unisys.

     Many of New Caldera's competitors have substantially greater financial and
technical resources, more extensive marketing and distribution capabilities;
larger development staffs and more widely recognized brands and products.

     Also, due to the open source nature of Linux, anyone can freely download
Linux and many Linux applications and modify and re-distribute them with few
restrictions. For example, solution providers upon whom New Caldera depends for
the distribution of its eBusiness products could instead create their own Linux
solutions to provide to their customers. Also, established companies and other
institutions could easily produce competing versions of Linux.

New Caldera's foreign-based operations and sales create special problems that
could hurt its results

     An investment in New Caldera is risky because it will have significant
foreign operations, including development facilities, sales personnel and
customer support operations. These foreign operations are subject to certain
inherent risks, including:

     - potential loss of developed technology through piracy, misappropriation,
       or more lenient laws regarding intellectual property protection;

     - imposition of governmental controls, including trade restrictions;

     - fluctuations in currency exchange rates and economic instability;

     - longer payment cycles for sales in foreign countries;

     - difficulties in staffing and managing the foreign operations;

     - seasonal reductions in business activity in the summer months in Europe
       and other countries; and

     - political unrest, particularly in areas in which New Caldera will have
       facilities.

     In addition, international sales will be denominated in local currency,
creating risk of foreign currency translation gains and losses that could harm
New Caldera's financial results. If New Caldera generates profits or losses in
foreign countries, its effective income tax rate could also be increased.

                                       17
<PAGE>   30

New Caldera's acquisition strategy involves risks

     New Caldera expects to pursue other acquisitions in the future.
Acquisitions involve a number of special risks and challenges, including:

     - management's attention may be diverted, particularly in the case of
       multiple concurrent acquisitions;

     - New Caldera must integrate the target's operations and employees with its
       existing business;

     - New Caldera may have difficulty incorporating technology into its
       existing product lines;

     - key employees may leave; and

     - New Caldera may have difficulty presenting a unified corporate image.

     New Caldera does not have experience in integrating the operations of
acquired companies.

Caldera and SCO could each be harmed if the combination is not completed

     Caldera and SCO have each expended substantial management time and incurred
costs in negotiating the combination. These costs will not be recouped if the
combination is not completed. If the combination is not completed, Caldera and
SCO will continue to operate as independent entities, despite customers' and
employees' expectations. Each of our reputations and relationships with
customers could be damaged if Caldera and SCO fail to complete the combination.
If Caldera or SCO does not complete the combination, in certain circumstances,
SCO or Caldera may be required to pay a significant breakup fee to the other
party.

New Caldera will be dependent upon certain strategic relationships with its
technology partners and the loss of any of these relationships could adversely
affect its business prospects

     New Caldera will depend on alliances with technology partners such as
Citrix Systems, Fujitsu, IBM, Intel Novell, Compaq and Sun Microsystems. These
relationships encompass product integration, two-way technology transfers, joint
marketing to electronic service providers and revenue-generating initiatives in
areas such as product bundles, training and education and third-level technical
support, relating to modification of the operating system code, for its
partners. New Caldera expects that these relationships will create opportunities
for its products and services in business markets in which it otherwise might
not have access. If New Caldera is unable to maintain these relationships, it
will not be able to develop and deploy its products in certain segments of the
business community and its product development and sales will not grow.

     In addition, existing strategic relationships of Caldera and SCO with
technology partners do not, and any future strategic relationships may not,
afford New Caldera any exclusive marketing development or distribution rights.
As a result, the companies with which New Caldera will have strategic alliances
are free to pursue alternative technologies and to develop alternative products
and services in addition to or in lieu of New Caldera's products and services,
either on their own or in collaboration with others, including competitors of
New Caldera. Moreover, New Caldera cannot guarantee that the companies with
which Caldera and SCO have strategic relationships will market New Caldera's
products effectively or continue to devote the resources necessary to provide it
with effective sales, marketing and technical support, or that these partners
will not choose to open source products into which Caldera and SCO have invested
significant time and resources, thereby reducing the value of New Caldera's
rights in these products.

A single stockholder will be able to exert significant control over New Caldera

     After the combination, Raymond J. Noorda will have beneficial ownership of
approximately 50.3% of our outstanding common stock. As a result, Mr. Noorda
could determine the outcome of actions that require stockholder approval. For
example, Mr. Noorda could delay or prevent a transaction in which stockholders
might receive a premium over the prevailing market price for their shares and
control changes in management.

                                RISKS OF CALDERA

Caldera has a limited operating history.

     Although Caldera began operations in 1994, during the past 24 months
Caldera has substantially revised its business plan to focus on Linux for
eBusiness, made additions to its product line and hired a significant number of
new employees, including key members of its management team. Caldera recently
developed and released its server product, eServer. Its historical sales have
been primarily from its OpenLinux products, including OpenLinux 2.3 (renamed
eDesktop because of its focus on the desktop environment), which were
historically developed for first-time Linux users who predominantly have
experience using Windows desktop environments. As a company in a new and rapidly
evolving industry, Caldera faces risks and uncertainties relating to its ability
to successfully implement its strategy. You must consider the risks, expenses
and uncertainties facing a company like Caldera, operating with an unproven
business model, faces in a new and rapidly evolving market such as the market
for Linux software. These risks also include Caldera's ability to:

     - broaden awareness of the Caldera Systems brand;

     - maintain its current, and develop new, strategic relationships with
       technology partners and solutions providers;

     - attract, integrate and retain qualified management personnel;

     - attract, integrate and retain qualified personnel for the expansion of
       its sales, professional services, engineering, marketing and customer
       support organizations;

     - continue to develop and upgrade product offerings tailored for business;

     - respond effectively to competitive pressures; and

     - generate revenue from the sale of software products, services, education
       programs and training.

     If Caldera cannot address these risks and uncertainties or is unable to
execute its strategy, Caldera may not be successful.

You should not rely on Caldera's quarterly operating results as an indication of
its future results because they are subject to significant fluctuations.
Fluctuations in Caldera's operating results or the failure of its operating
results to meet the expectations of public market analysts and investors may
negatively impact Caldera's stock price.

     Caldera's quarterly operating results have varied in the past and Caldera
expects them to fluctuate significantly in the future due to a variety of
factors that could affect revenue or expenses in any particular quarter.
Historically, Caldera has experienced substantial fluctuations in its software
and related products revenue from period to period relating to the introduction
of new products and new versions of its existing products. For example, revenue
from software and related products for the three-month period ended January 31,
1999 was approximately $508,000. Software and related products revenue decreased
to approximately $482,000 during the three-month period ended April 30, 1999 but
increased to approximately $1.0 million during the three-month period ended July
31, 1999. Software and related products revenue decreased to approximately
$775,000 during the three-month period ended October 31, 1999, further decreased
to approximately $395,000 during the three-month period ended January 31, 2000
and then increased to approximately $1.1 million for the three-month period
ended April 30, 2000. Software and related products revenue then decreased to
approximately $631,000 during the three-month period ended July 31, 2000. These
quarterly revenue fluctuations were primarily due to the fluctuation of sales of
Caldera's OpenLinux products, and these fluctuations in revenue can be expected
to continue as a result of fluctuating sales of all of Caldera's products,
including its new product offerings.

     Upon announcement of an expected release date for a new product or upgrade,
Caldera often experiences a significant decrease in sales of its existing
products. Additionally, Caldera often experiences

                                       19
<PAGE>   32

the strongest sales for a new product during the first 30 days after its
introduction as Caldera fills advance orders from its distribution channel.
Fluctuations in quarterly operating results could cause Caldera's stock price to
decline. You should not rely on quarter-to-quarter comparisons of Caldera's
results of operations as an indication of future performance. Factors that may
affect our quarterly results include:

     - the interest level of electronic solutions providers in recommending
       Caldera's Linux business solutions to end users;

     - the introduction, development, timing, competitive pricing and market
       acceptance of Caldera's products and services and those of its
       competitors;

     - changes in general economic conditions, such as recessions, that could
       affect capital expenditures and recruiting efforts in the software
       industry in general and in the Linux environment in particular;

     - the magnitude and timing of marketing initiatives;

     - changing business attitudes toward Linux as a viable operating system
       alternative to other competing systems;

     - the maintenance and development of Caldera's strategic relationships with
       technology partners and solution providers;

     - the attraction, retention and training of key personnel; and

     - Caldera's ability to manage anticipated growth and expansion.

     As a result of the factors listed above and elsewhere, it is possible that
in some future periods Caldera's results of operations may be below the
expectations of public market analysts and investors. This could cause Caldera's
stock price to decline. In addition, Caldera plans to increase its operating
expenses to expand its sales and marketing, administration, consulting and
training, maintenance and technical support and research and development groups.
If revenue falls below expectations in any quarter and Caldera is unable to
quickly reduce its spending in response, Caldera's operating results would be
lower than expected and Caldera's stock price may fall.

Caldera's business model, which relies on a combination of open source software
and proprietary technology, is unproven.

     Caldera's business model incorporates as integral elements of its product
offerings both commercial products and open source software. Caldera knows of no
company that has built a profitable business based in whole or in part on open
source software. By incorporating open source components in its product
offerings, Caldera faces many of the same risks that other open source companies
experience, including the inability to offer warranties and indemnities on
products and services. In addition, by developing products based on proprietary
technology that is not freely downloadable Caldera may run counter to the
perception of Linux as an open source model and alienate the Linux community.
For example, its business model has been criticized by some members of the open
source software community on various Web-based forums, including online
articles, electronic bulletin boards and online chat rooms. Others have asserted
that Caldera is trying to dominate the market for Linux operating systems much
like other companies have been able to dominate traditional software markets.
Caldera's critics argue that its business model, if successful, would fragment
the Linux community, resulting in a less cohesive and cooperative development
process. Negative reaction such as this, if widely shared by its customers,
developers or the open source community, could harm Caldera's reputation,
diminish its brand and decrease its revenue. Caldera's business will fail if it
is unable to successfully implement its business model.

     Caldera's business model also depends upon incorporating contributions from
the open source community into products that it open sources. The viability of
Caldera's product offerings depends in large measure upon the efforts of the
open source community in enhancing products and making them compatible for use
across multiple software and hardware platforms. There are no guarantees that
these products will be embraced by the open source community such that
programmers will contribute sufficient

                                       20
<PAGE>   33

resources for their development. If the open source community does not embrace
products that Caldera views as integral to providing eBusiness solutions,
Caldera will be required to devote significant resources to develop these
products on its own.

The sales cycle for Caldera's products is long and Caldera may incur substantial
non-recoverable expenses; Caldera devotes significant resources to sales that
may not occur when anticipated or at all.

     The length of time between initial contact with a potential customer and
sale of a product, or Caldera's sales cycle, outside the retail channel is
typically complex and lengthy, lasting from three to nine months. These direct
sales also represent Caldera's largest orders. Therefore, Caldera's revenue for
a period is likely to be affected by the timing of larger orders, which makes
the related revenue difficult to predict. Caldera's revenue for a quarter could
be reduced if large orders forecasted for a certain quarter are delayed or are
not realized. The cycle factors that could delay or defer an order, include:

     - time needed for technical evaluations of our software by customers;

     - customer budget restrictions;

     - customer internal review and testing procedures; and

     - engineering work needed to integrate our software with the customer's
       systems.

Caldera's products have relatively short life cycles.

     Caldera's software products have a limited life cycle and it is difficult
to estimate when they will become obsolete. If Caldera does not develop and
introduce new products before its existing products have completed their life
cycles, Caldera would not be able to sustain its level of sales. In addition, to
succeed, many customers must adopt Caldera's new products early in the product's
life cycle. Therefore, if Caldera does not attract sufficient customers early in
a product's life, it may not realize the amount of revenue that Caldera
anticipated for the product. Caldera cannot be sure that it will continue to be
successful in marketing its key products.

Caldera relies on independent developers in the open source community, such as
Linus Torvalds, in order to release upgrades of its Linux-based products.

     Many of the components of Caldera's software products, including the Linux
kernel, the core of the Linux operating system, are developed by independent
developers in the open source community and are available for inclusion in
Caldera's products without cost. Linus Torvalds, the original developer of the
Linux kernel, and a small group of independent engineers have in the past
developed and upgraded the Linux kernel. Neither Mr. Torvalds nor any
significant contributor to the Linux kernel is an employee of Caldera, and none
of these individuals are required to further update the Linux kernel. If these
independent developers and others in the open source community do not further
develop the Linux kernel and other open source software included in Caldera's
products on a timely basis, or at all, Caldera's ability to enhance its product
offerings will suffer. As a consequence, Caldera will be forced to rely to a
greater extent on its own development efforts or license commercial software
products as replacements, which would increase its expenses and delay
enhancements to its products. For example, in the past Caldera has sometimes
been unable to upgrade all open source components of a product in connection
with a proposed release because enhancements had not yet been made by these
independent developers. Any failure on the part of the kernel developers to
further develop and enhance the kernel could also stifle the development of
additional Linux applications.

Caldera's reliance on independent third parties who develop most of the software
included in its Linux products could result in delays or unreliable products and
damage to Caldera's reputation.

     Caldera's products consist of many different software components and
applications, most of which are developed by independent third parties over whom
Caldera has limited or no control. While Caldera uses
                                       21
<PAGE>   34

rigid engineering standards in testing the products or applications that Caldera
integrates in its products, Caldera cannot guarantee that it has selected or
will select in the future the most reliable components available in the market
or that it will successfully integrate the many components of its products. In
addition, if any of these third-party products are not reliable or available,
Caldera may have to develop them internally, which would significantly increase
its development expenses and delay the time to market. Caldera's customers could
be dissatisfied if any of these products fail to work as designed or if adequate
support is not provided, which could damage its reputation and lead to potential
litigation.

The market for Linux business solutions may not grow as Caldera anticipates.

     Caldera's strategy for marketing Linux solutions to businesses depends in
part upon its belief that many businesses will follow a trend away from the use
of networked computers linked by centralized servers and move toward the use of
distributed applications through thin appliance servers, or specialized servers,
Internet access devices and application service providers. Caldera is also
relying on electronic solution providers making these technologies available on
Linux and on Linux then becoming a desirable operating system under these
circumstances. Caldera also plans to market its Linux products for use on these
specialized servers and Internet access devices, which Caldera believes will
become widely used for eBusiness. However, if businesses, which at present favor
Microsoft and other non-Linux operating systems, do not adopt these trends in
the near future, or if Linux is not viewed as a desirable operating system in
connection with these trends, a significant market for our products may not
develop. Factors that may keep businesses from adopting these trends include:

     - costs of installing and implementing new hardware devices;

     - costs of porting legacy systems into new platforms;

     - security concerns regarding manipulation of data through application
       service providers;

     - limited adoption of Linux among businesses generally;

     - previous significant investments in competing systems;

     - lack of adequate Linux-trained professionals and support services;

     - lack of standards among Linux products and applications; and

     - lack of acceptance of the Internet as a medium for distributing business
       applications.

     Even if these trends toward distributed applications are adopted, if the
development of Linux products and Linux applications is not sufficient to meet
the needs of eBusiness, a significant market for Linux business solutions such
as Caldera's may not materialize.

Caldera could be prevented from selling or developing its products if the GNU
general public license and similar licenses under which its products are
developed and licensed are not enforceable.

     The Linux kernel and certain other components of Caldera's products have
been developed and licensed under the GNU General Public License and similar
licenses. These licenses state that any program licensed under them may be
liberally copied, used, modified and distributed freely, so long as all
modifications are also freely made available and licensed under the same
conditions. Caldera knows of no instance in which a party has challenged the
validity of these licenses or in which these licenses have been interpreted in a
legal proceeding. To date, all compliance with these licenses has been
voluntary. It is possible that a court would hold one or more of these licenses
to be unenforceable in the event that someone were to file a claim asserting
proprietary rights in a program developed and distributed under them. Any ruling
by a court that these licenses are not enforceable, or that Linux operating
systems, or significant portions of them, may not be liberally copied, modified
or distributed freely, would have the effect of preventing Caldera from selling
or developing its products, unless Caldera is able to negotiate a license to use
the software or replace the affected portions. These licenses could be
expensive, which could impair Caldera's ability to price its products
competitively.
                                       22
<PAGE>   35

Caldera is vulnerable to claims that its products infringe third-party
intellectual property rights, particularly because its products are comprised of
many distinct software components developed by thousands of independent parties.

     Caldera may be exposed to future litigation based on claims that its
products infringe the intellectual property rights of others. This risk is
exacerbated by the fact that most of the code in its products is developed by
independent parties over whom Caldera exercises no supervision or control and
who, themselves, might not have the same financial resources as Caldera to pay
damages to a successful litigant. Claims of infringement could require Caldera
to re-engineer its products or seek to obtain licenses from third parties in
order to continue offering its products. In addition, an adverse legal decision
affecting Caldera's intellectual property, or the use of significant resources
to defend against this type of claim, could place a significant strain on
Caldera's financial resources and harm its reputation.

Failure to protect Caldera's intellectual property rights adequately would
result in significant harm to its business.

     While much of the code for Caldera's products is open source, its success
depends significantly on Caldera's ability to protect its trademarks, trade
secrets and certain proprietary technology contained in its products. Caldera
relies on a combination of copyright and trademark laws, and on trade secrets
and confidentiality provisions and other contractual provisions to protect its
proprietary rights. These measures afford only limited protection. Some
trademarks that have been registered in the United States have been licensed to
Caldera, and Caldera has other trademark applications pending in the United
States. Effective trademark protection may not be available in every country in
which Caldera intends to offer its products and services. Caldera's means of
protecting its proprietary rights in the United States or abroad may not be
adequate and competitors may independently develop similar technologies. For
example, on March 15, 2000 Caldera received a letter from counsel of a third
party demanding that Caldera immediately stop using the term eServer in
connection with its products. The third party alleges that it is the owner of
the trademark ESERVER and several related marks. Caldera has responded to this
letter and has received no additional correspondence. Caldera's future success
will depend in part on its ability to protect its proprietary rights. Despite
Caldera's efforts to protect its proprietary rights and technologies,
unauthorized parties may attempt to copy aspects of Caldera's products or to
obtain and use trade secrets or other information that Caldera regards as
proprietary. Legal proceedings to enforce Caldera's intellectual property rights
could be burdensome and expensive and could involve a high degree of
uncertainty. These legal proceedings may also divert management's attention from
growing Caldera's business. In addition, the laws of some foreign countries do
not protect its proprietary rights as fully as do the laws of the United States.
If Caldera does not enforce and protect Caldera's intellectual property, its
business may suffer substantial harm.

Caldera may be liable as a result of information retrieved from or transmitted
over the Internet.

     Caldera may be sued for defamation, civil rights infringement, negligence,
copyright or trademark infringement, personal injury, product liability or other
legal claims relating to information that is published or made available on its
Web site and the other sites linked to it. These types of claims have been
brought, sometimes successfully, against providers of online services in the
past. Caldera could also be sued for the content that is accessible from its Web
site and through links to other Internet sites or through content and materials
that may be posted by members in chat rooms or on bulletin boards. Caldera's
insurance does not specifically provide for coverage of these types of claims
and therefore may not adequately protect it against these types of claims. In
addition, Caldera could incur significant costs in investigating and defending
such claims, even if Caldera ultimately is not liable. If any of these events
occur, its revenues and the value of your investment could be materially
adversely affected.

Caldera must achieve rapid market penetration of its products in order to
compete successfully.

     Because the Linux and eBusiness markets are new and emerging, companies
that are early in providing products and solutions for these markets will have
an advantage in building awareness and consumer loyalty. Therefore, in order for
Caldera to successfully market its products on a wide scale,

                                       23
<PAGE>   36

Caldera must rapidly achieve market penetration. For example, if Caldera is
unable to demonstrate the viability of its products through rapid growth:

     - software developers will be less likely to develop applications for its
       products;

     - Caldera will be unable to achieve economies of scale;

     - Caldera will be less able to negotiate favorable terms with distributors
       and other partners; and

     - customers will be less likely to devote resources to purchasing and
       implementing its products if they are not seen as an industry standard.

     Caldera may lack the economic and managerial resources necessary to promote
this growth. Also, the fact that Caldera relies almost entirely on the success
of a few principal products affects its ability to penetrate diversified
markets. In addition, while Caldera believes its process of self-hosting results
in superior products, it requires time and resources that may delay new product
releases and upgrades. These delays could affect its ability to take advantage
of market opportunities on a timely basis.

Caldera's brand may not achieve the broad recognition necessary to succeed.

     Caldera believes that broad recognition and a favorable audience perception
of the Caldera brand will be essential to its success. If Caldera's brand does
not achieve broad recognition as the leading provider of Linux solutions for
eBusiness, our success will be limited. Caldera intends to build brand
recognition through advertising its products and services. During the fiscal
year ended October 31, 1999, Caldera spent approximately $1.2 million for
advertising. During the nine-month period ended July 31, 2000, Caldera spent
approximately $1.0 million for advertising. Caldera expects to increase its
advertising expenses in future periods as Caldera builds the Caldera brand and
awareness of Caldera's products and services. In addition, Caldera provides
education and training to build brand recognition, which may not be successful
if Caldera is unable to generate wide-acceptance of these services. Caldera may
lack the resources necessary to accomplish these initiatives. Even if the
resources are available, Caldera cannot be certain that its brand enhancement
strategy will deliver the brand recognition and favorable audience perception
that Caldera seeks. If Caldera's strategy is unsuccessful, these expenses may
never be recovered and Caldera may be unable to increase future revenues. Even
if Caldera achieves greater recognition of its brand, competitors with greater
resources or a more recognizable brand could reduce its market share of the
emerging Linux market, as well as the broader market for the provision of
eBusiness solutions.

Caldera's strategy to provide solutions for eBusiness depends upon its ability
to successfully introduce products tailored for eBusiness.

     To date, practically all of its sales revenue has come from retail sales of
OpenLinux, which is designed to assist the first-time Linux user who may be
familiar with a Windows, desktop environment. However, Caldera's business model
is targeted toward using Linux solutions to facilitate eBusiness. In order for
our strategy of providing Linux solutions for eBusiness to be successful,
Caldera must provide products that meet the needs of solution providers and
their eBusiness customers. Caldera recently developed its server product,
OpenLinux eServer. This new product, which is Caldera's primary eBusiness
product, may not be adopted by solution providers and their customers for any
number of reasons, including lack of customer awareness of Caldera and its
products, malfunction of the products and failure to meet needs of eBusiness. If
Caldera's eBusiness products are not successful, Caldera will fail to execute
its strategy and its sales may not grow.

Caldera could lose revenue as a result of software errors or defects.

     Software programs frequently contain errors or defects, especially when
first introduced or when new versions are released. Caldera could, in the
future, lose revenue as a result of errors or defects in its software products.
Caldera cannot assure you that errors will not be found in new products or
releases. Although Caldera has both product liability and errors and omissions
insurance, Caldera might incur losses in excess of the dollar limits or beyond
the scope of coverage of its policies. While Caldera tests its products prior to
release, the fact that most of the components of its software offerings are
developed by independent parties over whom Caldera exercises no supervision or
control makes it particularly difficult to

                                       24
<PAGE>   37

identify and remedy any errors or defects that could exist. Any errors could
result in loss of revenue, or delay in market introduction or acceptance,
diversion of development resources, damage to its reputation or increased
service costs.

Caldera's current and potential customers may find it difficult to hire and
train qualified employees to handle installation and implementation of its
products, which could negatively affect sales of its products to new customers
and lead to dissatisfaction among current customers.

     There are limited numbers of individuals that are trained and qualified to
manage Linux systems, including OpenLinux and our other products. End users and
Caldera's distribution partners may lack the resources to hire or train such
qualified personnel to install and implement Caldera's products, which could
lead to dissatisfaction with Caldera's products among end users and deter
potential end users from purchasing Caldera's product.

The growth of Caldera's business will be diminished if the Internet is not
accepted as a medium for commerce and business networking applications.

     An important part of Caldera's business strategy is to develop and market
its products for the support of secure business networks hosted on the Internet.
In addition, Caldera plans to sell its products and provide a significant amount
of technical support and education via its Web site. If the Internet is not
accepted as a medium for commerce and business networking applications, demand
for its products and services will be diminished. A number of factors may
inhibit Internet usage, including:

     - inadequate network infrastructure;

     - lack of knowledge and training on Internet use and benefits;

     - consumer concerns for Internet privacy and security;

     - lack of availability of cost-effective, high-speed service;

     - interruptions in Internet commerce caused by unauthorized users;

     - changes in government regulation relating to the Internet; and

     - Internet taxation.

     If Internet usage grows, the infrastructure may not be able to support the
demands placed on it by that growth and its performance and reliability may
decline. Web sites have experienced interruptions as a result of delays or
outages throughout the Internet infrastructure. If these interruptions continue,
Internet usage may decline.

Future sales of Caldera's common stock may negatively affect its stock price.

     The market price of Caldera's common stock could decline as a result of
sales of a large number of shares of Caldera common stock in the market in the
future, or the perception that such sales could occur. Caldera has a large
number of shares of common stock outstanding and available for resale beginning
at various points in time in the future. These sales also might make it more
difficult for Caldera to sell equity securities in the future at a time and at a
price that it deems appropriate. The shares of Caldera common stock currently
outstanding will become eligible for sale without registration pursuant to Rule
144 under the Securities Act, subject to certain conditions of Rule 144,
including the shares issued to SCO in the combination.

                              THE CALDERA MEETING

WHEN AND WHERE THE MEETING WILL BE HELD

     We will hold a special meeting of Caldera Systems, Inc. stockholders at
Caldera's offices at 240 West Center Street, Orem, Utah on                , 2000
at 8:00 a.m. Mountain time to consider and vote on the proposals set forth
below.

WHAT WILL BE VOTED UPON

     At the Caldera meeting, you will be asked to approve the following
proposals:

     - To combine Caldera with the server and professional services groups of
       The Santa Cruz Operation, Inc. In connection with the combination, SCO
       and its employees who join Caldera, Inc. will receive approximately 28.6%
       of Caldera, Inc. or 18.4 million shares of Caldera, Inc. common stock
       (including approximately two million shares reserved for employee options
       assumed or replaced by Caldera, Inc. for options currently held by SCO
       employees joining Caldera, Inc.), and SCO will receive $7 million in
       cash. In the combination, Caldera will become a subsidiary of a new
       parent company, which we call New Caldera, and SCO will contribute to New
       Caldera the assets of its server and professional services groups.

     - To amend our 1999 Omnibus Stock Incentive Plan to increase the number of
       shares reserved for issuance from 4,105,238 to 6,405,238 and to provide
       for an automated director option grant program.

     - To amend our 2000 Employee Stock Purchase Plan to increase the number of
       shares reserved for issuance from 500,000 to 2,000,000.

     - To amend our Certificate of Incorporation to increase the authorized
       number of shares of common stock from 75,000,000 to 175,000,000.

     - To transact such other business as may properly come before the special
       meeting or any adjournment or postponement thereof.

     We do not anticipate that any matter will be presented for action at the
meeting. If any other material matters are properly brought before the meeting,
we will re-solicit proxies.

ONLY STOCKHOLDERS ON              , 2000 WILL BE ENTITLED TO VOTE

     You will be entitled to vote at the Caldera meeting only if you are a
holder of record of shares of Caldera common stock at the close of business on
            , 2000, the Caldera record date. On that date, there were
shares of Caldera common stock outstanding and entitled to vote. These shares
were held of record by approximately           stockholders.

     Each Caldera stockholder is entitled to one vote for each share of Caldera
common stock held on the Caldera record date for each matter to be acted upon in
the Caldera meeting.

     On September 1, 2000, directors and executive officers of Caldera and their
affiliates as a group held 29.7 million shares of Caldera common stock, or
approximately 74.2% of the outstanding shares of Caldera common stock. The
Canopy Group, Inc. and MTI Technology Corporation, affiliates of Caldera, have
executed voting agreements with SCO, under which they have agreed to vote all of
their shares in favor of the combination.

VOTES NEEDED FOR A QUORUM

     The required quorum for the transaction of business at the meeting is a
majority of the shares of Caldera common stock outstanding on the Caldera record
date.

EFFECT OF ABSTENTIONS AND BROKER NON-VOTES

     Abstentions and broker non-votes will be included in determining the number
of shares present and voting at the meeting. Abstentions will have the same
effect as votes against all of the proposals.

     For the proposals relating to the combination and the amendment to the
Caldera certificate of incorporation, broker non-votes will have the same effect
as votes cast against the proposals.

     For each of the proposals relating to the Caldera equity incentive plans
broker non-votes will have no effect.

CALDERA WILL PAY THE EXPENSES OF PROXY SOLICITATION

     Caldera will pay the expenses of soliciting proxies to be voted at the
meeting. Following the original mailing of the proxies and other soliciting
materials, Caldera and its agents also may solicit proxies by mail, telephone,
telegraph or in person.

     Following the original mailing of the proxies and other soliciting
materials, Caldera will request brokers, custodians, nominees and other record
holders of Caldera common stock to forward copies of the proxy and other
soliciting materials to persons for whom they hold shares of Caldera common
stock and to request authority for the exercise of proxies. In these cases,
Caldera, upon the request of the record holders, will reimburse the holders for
their reasonable expenses.

HOW PROXIES WILL BE VOTED

     All properly executed proxies received by Caldera prior to the vote at the
meeting that are not revoked will be voted at the meeting according to the
instructions indicated on the proxies. If no direction is indicated, they will
be voted to approve each of the proposals.

HOW YOU CAN REVOKE YOUR PROXY

     A Caldera stockholder who has given a proxy may revoke it at any time
before it is exercised at the meeting, by:

     - delivering to the Secretary of Caldera by any means, including facsimile,
       a written notice, bearing a date later than the date of the proxy,
       stating that the proxy is revoked;

     - signing and so delivering a proxy relating to the same shares and bearing
       a later date prior to the vote at the meeting; or

     - attending the meeting and voting in person, although attendance at the
       meeting will not, by itself, revoke a proxy.

     Please note, that if your shares are held of record by a broker, bank or
other nominee and you wish to vote at the meeting, you must bring to the Caldera
meeting a letter from the broker, bank or other nominee confirming your
ownership of the shares.

YOU DO NOT HAVE DISSENTERS' OR APPRAISAL RIGHTS

     You are not entitled to dissenters' rights or appraisal rights with respect
to any proposals to be considered at the Caldera meeting.

YOU MUST ACT BY A SPECIFIED DATE TO PRESENT A STOCKHOLDER PROPOSAL AT THE NEXT
CALDERA ANNUAL MEETING

     Stockholders are entitled to present proposals for action at a forthcoming
meeting if they comply with the requirements of the proxy rules established by
the Securities and Exchange Commission. In order for submitted proposals by New
Caldera stockholders to be considered for inclusion in the proxy statement for
the next annual meeting of New Caldera stockholders if the combination is
approved, the proposals must be received a reasonable time before New Caldera
begins to print and mail its proxy materials. If the combination is not
approved,             , 2000 will be the deadline for the submission of
proposals for the next Caldera annual meeting.

     If a stockholder intends to submit a proposal at the next annual meeting of
New Caldera stockholders which is not eligible for inclusion in the proxy
statement relating to that meeting, the stockholder must give notice to New
Caldera in accordance with the requirements set forth in the Securities Exchange
Act no later than a reasonable time before New Caldera mails its proxy materials
for the meeting. If the combination is not approved,             , 2000 will be
the deadline for giving notice to Caldera of the intent to submit a proposal at
the next Caldera annual meeting. If a stockholder fails to comply with this
notice provision, the proxy holders will be allowed to use their discretionary
voting authority when and if the proposal is raised at that meeting, or the
annual meeting of New Caldera stockholders if the combination is approved.

                                THE SCO MEETING

WHEN AND WHERE THE MEETING WILL BE HELD

     A special meeting of the shareholders of SCO will be held at
               a.m., local time, on                ,             , 2000, at
               .

WHAT WILL BE VOTED UPON

     At the SCO meeting, you will be asked to approve the following proposals:

     - To approve and adopt the agreement and plan of reorganization, dated
       August 1, 2000 and amended on September 13, 2000, by and among The Santa
       Cruz Operation, Inc., Caldera Systems, Inc., and Caldera, Inc.

     - To approve an amendment to SCO's articles of incorporation to change our
       corporate name to "Tarantella, Inc."

     - To transact such other business as may properly come before the special
       meeting or any adjournment or postponement thereof.

RECORD DATE AND OUTSTANDING SHARES

     SCO's board of directors has fixed the close of business on             ,
2000 as the record date for the special meeting. You will be entitled to vote at
the SCO special meeting only if you are a holder of record of shares of SCO
common stock at the close of business on the SCO record date. On that date,
there were           shares of SCO common stock outstanding and entitled to
vote. These shares were held of record by approximately           shareholders.
SCO has been informed that there are in excess of           beneficial owners.

VOTING RIGHTS AND VOTES REQUIRED TO APPROVE THE PROPOSALS

     Each SCO shareholder is entitled to one vote for each share of SCO common
stock you held on the SCO record date for each matter to be acted upon in the
SCO meeting.

     The approval and adoption of each proposal by the SCO shareholders
described above will require the affirmative vote of a majority of the
outstanding common stock.

SHARES HELD BY DIRECTORS, EXECUTIVE OFFICERS AND THEIR AFFILIATES

     On August 15, 2000, directors and executive officers of SCO and their
affiliates as a group beneficially owned approximately 16.8% of the outstanding
shares of SCO common stock. Doug Michels, Chief Executive Officer and President
of SCO, has executed a voting agreement with Caldera, under which he has agreed
to vote all of his shares in favor of approving and adopting the reorganization
agreement.

QUORUM, ABSTENTIONS AND BROKER NON-VOTES

     The required quorum for the transaction of business at the meeting is a
majority of the shares of SCO common stock issued and outstanding on the SCO
record date.

     Abstentions will be included in determining the number of shares present
and voting at the meeting and will have the same effect as votes against all of
the proposals.

     While there is no definitive statutory or case law authority in California
as to the proper treatment of abstentions in the counting of votes with respect
to a proposal, SCO believes that abstentions should be counted for purposes of
determining both (i) the presence or absence of a quorum for the transaction of
business and (ii) the total number of votes cast with respect to the proposal.
In the absence of controlling precedent to the contrary, we intend to treat
abstentions in this manner. Accordingly, abstentions will have

                                       31
<PAGE>   44

the same effect as a vote against the proposal. Broker non-votes, shares held by
brokers that are present but not voted because the brokers were prohibited from
exercising discretionary authority ("broker non-votes"), will be counted for
purposes of determining the presence or absence of a quorum for the transaction
of business, but will not be counted for purposes of determining the number of
votes cast with respect to the proposal.

SOLICITATION OF PROXIES

     SCO will pay the expenses of soliciting proxies to be voted at the meeting.
Following the original mailing of the proxies and other soliciting materials,
SCO and its agents also may solicit proxies by mail, telephone, telegraph,
e-mail or in person. SCO has retained a proxy solicitation firm, Skinner &
Company, to aid it in the solicitation process. SCO will pay that firm a fee
equal to $7,500. Following the original mailing of the proxies and other
soliciting materials, SCO will request brokers, custodians, nominees and other
record holders of SCO common stock to forward copies of the proxy and other
soliciting materials to persons for whom they hold shares of SCO common stock
and to request authority for the exercise of proxies. In these cases, SCO, upon
the request of the record holders, will reimburse the holders for their
reasonable expenses. Proxies may also be solicited by certain of SCO's
directors, officers and regular employees, without additional compensation,
personally, by telephone or by e-mail.

HOW PROXIES WILL BE VOTED

     All properly executed proxies received by SCO prior to the vote at the
meeting that are not revoked will be voted at the meeting according to the
instructions indicated on the proxies. If no direction is indicated, they will
be voted to approve each of the proposals.

HOW YOU CAN REVOKE YOUR PROXY

     An SCO shareholder who has given a proxy may revoke it at any time before
it is exercised at the meeting, by:

     - delivering to the Secretary of SCO by any means, including facsimile, a
       written notice, bearing a date later than the date of the proxy, stating
       that the proxy is revoked;

     - signing and so delivering a proxy relating to the same shares and bearing
       a later date prior to the vote at the meeting; or

     - attending the meeting and voting in person, although attendance at the
       meeting will not, by itself, revoke a proxy.

     Please note, that if your shares are held of record by a broker, bank or
other nominee and you wish to vote at the meeting, you must bring to the SCO
meeting a letter from the broker, bank or other nominee confirming your
ownership of the shares.

DISSENTERS' RIGHTS

     If the reorganization agreement is approved by SCO shareholders, SCO
shareholders who elect to dissent from the approval and who follow the
procedural requirements of Chapter 13 of the California Corporations Code may,
under certain circumstances, be entitled to receive cash for their SCO common
stock at their fair market value. A copy of Chapter 13 of the California
Corporations Code is attached to this document as Appendix N.

DEADLINE FOR RECEIPT OF SHAREHOLDER PROPOSAL

     SCO shareholders are entitled to present proposals for action at a
forthcoming meeting if they comply with the requirements of the proxy rules
established by the Securities and Exchange Commission. In order for submitted
proposals by shareholders to be considered for inclusion in the proxy statement
for the next

                                       32

annual meeting of shareholders, the proposals must be received in a reasonable
time before SCO begins to print and mail its proxy materials. Proposals of SCO
shareholders that are intended to be presented for consideration at SCO's 2001
annual meeting of shareholders must be received by SCO no later than September
23, 2000 in order that they may be considered for inclusion in the proxy
statement and form of proxy relating to that meeting.

2000. If a shareholder fails to comply with this notice provision, the proxy
holders will be allowed to use their discretionary voting authority when and if
the proposal is raised at that meeting, or the annual meeting of SCO
shareholders.

                                THE COMBINATION

     This section of the joint proxy statement/prospectus describes aspects of
the proposed merger that we consider important. While we believe that the
subscription covers the material terms of the combination and related
transactions, this summary may not contain all the information that is important
to Caldera stockholders and SCO shareholders. Stockholders and shareholders
should read the merger agreement and the other documents we refer to carefully
and in their entirety for a more complete understanding of the combination.

BACKGROUND OF THE COMBINATION

     The Linux and Unix industries are highly competitive. Since each company's
inception Caldera and SCO have continually evaluated strategic relationships of
various forms with various third parties in their efforts to enhance their
market position and grow their businesses in an increasingly competitive
environment. Over time, representatives of Caldera and SCO became familiar with
each others' products through informal contacts at industry trade shows and
through interaction with various industry participants.

     On March 23 and 24, 2000 Ransom Love, President and Chief Executive Officer
of Caldera, met with Doug Michels, President and Chief Executive Officer of SCO,
to discuss a possible transaction between the two companies.

     On April 21, 2000 Messrs. Love and Michels met again regarding pursuing a
relationship between Caldera and SCO.

     On May 10, 2000, officers of Caldera met with Broadview International LLC
to discuss risks and opportunities concerning a potential transaction with SCO.

     On May 15, 2000, SCO entered into a financial advisory services agreement
with Chase H&Q.

     On May 18, 2000, Caldera and SCO entered into a mutual non-disclosure
agreement allowing for the exchange of non-public information.

     On May 23, 2000, officers of Caldera and representatives of Broadview met
with officers of SCO and representatives of Chase H&Q to discuss potential
structure and synergies of a transaction.

     On June 5, 2000 representatives of Caldera and Broadview met with
representatives of SCO and Chase H&Q to discuss how the business plans of the
two companies might integrate and to develop cost and revenue models for the
possible new entity.

     On June 6, 2000, Caldera retained Broadview International LLC to act as its
financial advisor in connection with a possible transaction between Caldera and
SCO and signed an engagement letter.

     On June 7, 2000, Caldera and Broadview proposed an acquisition to SCO and
Chase H&Q of SCO's open server business in return for a percentage ownership in
the combined company, with a portion of future operating income from the open
server business to go to SCO. Over the course of the following week, officers of
SCO and Caldera exchanged proposals for a potential transaction. On June 13,
2000, the parties reached a tentative agreement in principle as to the structure
of the transaction.

     On June 14, 2000, the board of directors of SCO met to discuss the proposal
combination with Caldera. The SCO board authorized its officers to conduct due
diligence, and to continue discussions and negotiations regarding the potential
combination.

     On June 16 and 19, 2000, the board of directors of Caldera met in person
and telephonically to discuss the proposed combination with SCO. The board of
Caldera authorized officers of Caldera to conduct due diligence, continue
discussions concerning the terms of the combination and negotiate the terms of
the reorganization agreement.

                                       34
<PAGE>   47

     On June 23, 2000, representatives of Broadview and Chase H&Q met to discuss
possible no-shop language for both companies during the negotiation process.

     On June 25, 2000, Caldera and SCO entered into a letter agreement
concerning restrictions on public announcements by either party and restrictions
on negotiations by SCO with third parties regarding transactions relating to
SCO's server division through July 26, 2000.

     On June 28, 2000, counsel to Caldera distributed the first draft of the
reorganization agreement. Representatives of Caldera and SCO met to discuss the
Asian and Latin American components of SCO's current business strategy.

     On June 29, 2000, officers of Caldera reviewed with officers of SCO
business and financial information in connection with SCO's due diligence.

     During July 2000, additional meetings and telephone conferences took place
between the marketing, communications and human resources teams from Caldera and
SCO for the purpose of due diligence and planning logistics of public and
internal announcements in the event the parties reached agreement on the
material terms of the proposed combination. The companies also discussed
providing information regarding the combination of employees and customers if
they reached an agreement regarding the contribution of SCO's server business to
the combined company.

     On July 14, 2000, after conducting due diligence, Caldera proposed to
re-structure certain terms of the proposed transaction. SCO rejected this
proposal and sent a letter to Caldera purporting to unilaterally terminate the
restrictions on negotiations by SCO contained in the June 26, 2000 letter
agreement.

     On July 19, 2000 and again on July 21, 2000, the SCO board met to discuss
the direction of the company and the proposed combination in light of recent
events involving Caldera and SCO, and instructed management to report back with
any further developments.

     On July 23, 2000, officers of the two companies discussed renewing
negotiations concerning the proposed combination.

     On July 25, 2000, Mr. Love met with Mr. Michels in Santa Cruz, California
and discussed the terms of and implementation of the combination. During this
discussion, Mr. Michels suggested that Caldera and The Canopy Group, one of
Caldera's major stockholders, loan up to an aggregate of $25 million to SCO for
purposes of helping SCO pay restructuring and operating costs that would arise
between signing of the reorganization agreement and the closing of the
combination.

     On July 26, 2000, SCO management briefed the SCO board on the latest
discussions with Caldera. The SCO board authorized the officers to continue
negotiating the terms of the reorganization agreement and any ancillary
agreements related to the combination.

     From July 25, 2000 through July 28, 2000, officers of and counsel for the
two companies met in Palo Alto, California and Santa Cruz, California to
negotiate and finalize the terms of the reorganization agreement, the voting
agreements and related forms of agreements to be entered into at the closing of
the combination. During these discussions, the companies also discussed the
purchase by the combined company of the professional services division of SCO.
Officers of the two companies settled on including the assets of the
professional services division with the other assets of SCO to be sold to the
combined entity pursuant to the reorganization agreement, in return for
increasing the purchase price by $7 million in cash. However, as a condition to
SCO entering into the reorganization agreement on these terms, SCO would require
that a loan of $7 million would be provided to SCO by Caldera at the time of
signing the reorganization agreement. This loan would be unsecured, but if not
paid before the maturity date, it would convert into shares of common stock of
SCO at up to a 20% discount from the fair market value of SCO's shares at that
time.

     On July 31, 2000, the board of directors of each of Caldera and SCO met to
consider the proposed combination and the related transactions. The boards
reviewed, among other things, the background of the proposed combination,
strategic alternatives, financial and valuation analyses of the transaction, and
the

                                       35
<PAGE>   48

terms of the combination. During the meetings, the boards of Caldera and SCO
each received an oral financial fairness opinion from their respective financial
advisors, which was subsequently confirmed in writing. After extensive
discussion and consideration, the board of directors of SCO approved the terms
of the combination and authorized its officers to complete the terms of the
reorganization agreement and the ancillary agreements. The board of directors of
Caldera, however, expressed concern in lending $7 million unsecured to SCO, and
instructed the officers to negotiate with SCO concerning receiving adequate
security for the loan amount.

     On August 1, 2000, the officers of the two companies discussed the terms of
a binding memorandum of understanding whereby Caldera would commit to providing
a secured loan to SCO in the amount of $7 million, so long as The Canopy Group
also executed a binding memorandum of understanding in which it would commit to
provide a secured loan to SCO in the amount of $18 million. The board of
directors of each of Caldera and SCO then reconvened to discuss the revised
terms of the loan financings. After extensive discussion and consideration, the
boards of each company approved the terms of the combination and revised loan
financing and authorized its officers to complete the terms of the
reorganization agreement and the ancillary agreements, including the binding
memorandum of understanding between SCO and Caldera. Each company then executed
and delivered the reorganization agreement. Voting agreements between The Canopy
Group and MTI Technology Corporation and SCO and between Doug Michels and
Caldera were simultaneously executed, as were the binding memorandums of
understanding concerning the loan financing.

     On August 2, 2000, the companies announced the entering into the
reorganization agreement by the issuance of a joint press release.

     To date, by mutual agreement, notes formalizing the secured loans to SCO
from Caldera and Canopy have not been executed.

REASONS FOR THE COMBINATION

     The SCO board and the Caldera board unanimously recommend that the
shareholders and the stockholders of their respective companies vote "FOR" the
approval and adoption of the combination for the reasons set forth below.

Joint reasons for the combination

     We have identified a number of potential mutual benefits of the combination
that we believe will contribute to the success of New Caldera.

     These potential benefits include:

     - The operating system software industry in which we both compete is
       extremely competitive. We recognized that substantial technical,
       financial and other resources are necessary to compete with these larger,
       more diversified operating system software companies. The combination may
       allow each of us, through our participation in New Caldera, to achieve
       greater scale and greater presence in the operating systems software
       industry. We believe New Caldera will have a stronger position from which
       to compete more effectively against larger software companies. Our
       combined experience, financial resources, size, complementary product
       offerings and the complementary scope of distribution channels may allow
       New Caldera to respond more quickly and effectively to technological
       change, increased competition and customer demands in an industry
       experiencing rapid innovation and change;

     - The combined research and development and technology resources resulting
       from the combination may allow us to compete more effectively by
       developing more advanced products in a shorter time period than either of
       us could develop independently. Because achieving a rapid rate of
       technical innovation in the operating system software industry is
       critical, increasing our technical personnel

                                       36
<PAGE>   49

may permit us to respond more quickly and effectively to changes and to
anticipate the advancements in our industry more readily;

     - The product portfolios of Caldera and SCO's server business are
       complementary. Products and technologies developed for SCO's Unix
       platform can be ported for use with Caldera's Linux product offerings and
       would create the opportunity for us to create and deliver a broader range
       of solutions for eBusiness;

     - We anticipate that we will benefit from the combined original equipment
       manufacturer and strategic alliance partner relationships of Caldera and
       the server and professional services groups, which include many industry
       leaders, including Compaq, Hewlett-Packard, IBM and Sun Microsystems,
       among others;

     - The server and professional services groups' direct sales, value
       added-reseller and original equipment manufacturer channels complement
       Caldera's retail distribution capability, giving us the opportunity to
       access a broader range of key management sales channels and market
       segments;

     - The combination of the server and professional services groups and
       Caldera's Linux business will give us the opportunity to benefit from
       economies of scale generated by our greater critical mass when addressing
       the eBusiness solution needs of large global businesses; and

     - The global development infrastructure allows not only worldwide
       development cycles but the Unix and Linux engineers can take advantage of
       synergies in their respective expertises.

     In addition to the joint reasons discussed above, the board of directors of
each company also considered separate reasons for approving the combination,
which are summarized below.

Caldera's reasons for the combination

     The Caldera board of directors believes the following are additional
reasons for stockholders of Caldera to vote "For" approval and adoption of the
combination:

     - The server and professional services groups have a comprehensive,
       international, multi-tiered distribution channel, including several joint
       venture, value added resellers and original equipment manufacturers.
       These could provide New Caldera with significant additional opportunities
       to market its Linux offerings domestically and internationally;

     - The server and professional services groups have an extensive
       international infrastructure that could accelerate New Caldera's ability
       to market Linux technologies in foreign markets;

     - The server and professional services groups own and have rights to
       several technologies that, if ported for use on a Linux platform, could
       significantly expand Caldera's Linux product offerings; and

     - New Caldera would have significantly higher revenue than Caldera. New
       Caldera's pro forma net revenue was $108.8 million for fiscal 1999 and
       $70.5 million for the nine months ended July 31, 2000. We believe these
       revenue streams could provide greater flexibility for purposes of
       financing operations of New Caldera.

     In the course of its deliberations, the Caldera board of directors reviewed
with Caldera's management a number of factors relevant to the combination.

     In particular, it considered, among other things:

     - The proposed terms of the combination, including the terms of the
       stockholder agreement, the voting agreements, the sales representative
       and support agreement, the convertible note and related security
       agreements, the proposed employment agreements and other ancillary
       agreements;

     - The likelihood of realizing superior benefits through alternative
       business strategies, including internal growth and development;

                                       37
<PAGE>   50

     - The likelihood of leveraging current distribution channels of the server
       and professional services groups to increase sales opportunities for
       Caldera's Linux products;

     - Information concerning Caldera's and the server and professional services
       groups' respective businesses, historical financial performances,
       operations and products, including the due diligence reports from
       Caldera's management and legal, accounting and financial advisers;

     - The possibility of synergies from combining the Caldera and the server
       and professional services groups product lines;

     - An analysis of the relative value that the server and professional
       services groups might contribute to the future business and prospects of
       New Caldera;

     - The financial analysis presented by its financial advisor and the opinion
       that its financial advisor delivered that as of the date of such opinion
       and based upon the limitations set forth therein, the consideration to be
       paid for the server and professional services groups was fair from a
       financial point of view to Caldera. See "-- Opinions of Financial
       Advisors" on pages 40 and 45; and

     - The likelihood of increasing profitability of the server and professional
       services groups through reducing costs.

     The Caldera board of directors also considered certain risks that could
arise in connection with the combination, including:

     - The difficulties of successfully integrating such a large company into
       Caldera, managing geographically dispersed operations and the risk that
       employees of the server and professional services groups may not stay
       with New Caldera;

     - The effect on Caldera's business of declining revenue streams from the
       server and professional services group;

     - The risk that synergies and cost savings anticipated by the combination
       would not be achieved;

     - The potential disruption of Caldera's business that might result from
       employee and customer uncertainty and lack of focus following
       announcement of the combination or the integration of the operations of
       Caldera and the server and professional services group;

     - The risks of product integration due to overlapping products and
       technology;

     - The possibility that the combination might not close;

     - The substantial accounting charges to be incurred due to the combination
       related to the write-off of in-process research and development and the
       substantial amount of intangible assets that would have to be amortized
       as a result of the combination being accounted for as a purchase;

     - The risk that redundancy in staffing and infrastructure could reduce
       efficiency and increase costs;

     - The risk that the other benefits sought to be achieved by the combination
       will not be achieved; and

     - The other risks described under "Risk Factors" on page 14.

     In the view of the Caldera board, these risks were not sufficient either
individually or in the aggregate to outweigh the advantages of the combination.
In view of the wide variety of factors, both positive and negative, considered
by the Caldera board, the Caldera board did not find it practical to and did not
quantify or otherwise assign relative weights to the specific factors
considered.

     For the reasons discussed above, Caldera's board of directors has
unanimously approved the reorganization agreement and the combination and has
determined that the combination is advisable and in the best interests of
Caldera and its stockholders and unanimously recommends that Caldera
stockholders vote "FOR" approval of the reorganization agreement and the
combination.

SCO's reasons for the combination

     At a meeting held on July 31, 2000, the SCO board of directors concluded
that the combination was in the best interests of SCO and its shareholders and
determined to recommend that the shareholders approve and adopt the
reorganization agreement and approve the combination. In its evaluation of the
merger, the SCO board of directors identified several potential benefits of the
combination, the most important of which included the board's belief that the
combination would:

     - combine SCO, the world's leader in UNIX server operating systems, with
       Caldera, a leader in the rapidly growing open source movement and a
       leading provider of "Business Linux," resulting in the very best range of
       products for both companies' existing customers and channel partners;

     - enable SCO to monetize its server and professional services groups and
       receive publicly traded New Caldera common stock, immediate cash to fund
       the Tarantella business and future revenue from the Open Server product
       line; and

     - permit SCO's management to focus on the Tarantella business.

     SCO's board of directors consulted with senior management, as well as its
legal counsel, independent accountants and financial advisors, in reaching its
decision to approve the combination. In its evaluation of the combination, the
SCO board reviewed several factors, including, but not limited to, the
following:

     - SCO management's view of the financial condition, results of operations
       and business of SCO and Caldera before and after giving effect to the
       combination and SCO's determination of the combination's effect on
       shareholder value;

     - historical information concerning SCO's and Caldera's business, financial
       performance and condition, operations, technology and management,
       including reports concerning results of operations during the most recent
       fiscal period filed with the Securities and Exchange Commission;

     - the consideration to be received by SCO in the combination in light of
       comparable transactions;

     - the current and prospective industry environment for SCO's products and
       services;

     - current financial market conditions and historical market prices,
       volatility and trading information for Caldera and SCO;

     - the opinion of Chase H&Q that, as of the date of its opinion and based
       upon and subject to the assumptions made, matters considered and limits
       of the review undertaken by Chase H&Q, the consideration to be received
       in connection with the combination was fair from a financial point of
       view to SCO;

     - the belief that the terms of the reorganization agreement are reasonable;

     - the potential impact of the combination on SCO's customers, channel
       partners and employees;

     - discussions with its management, legal and financial advisors as to the
       results of the due diligence investigation of Caldera; and

     - the expectation that the combination will be a reorganization for United
       States federal income tax purposes.

     The SCO board also identified and considered a number of potentially
negative factors in its deliberations concerning the combination including the
following:

     - the risk that the potential benefits of the combination may not be
       realized;

     - uncertain prospects for the Linux market;

     - the difficulty and risk associated with the integration of management and
       organizational structures;

                                       39
<PAGE>   52

     - the effect of the public announcement and consummation of the combination
       on Caldera's and SCO's existing customers and channel partners;

     - limited visibility into the near and long-term financial performance of
       New Caldera;

     - the possibility that the combination may not be consummated; and

     - other applicable risks described in this joint proxy statement/prospectus
       under "Risk Factors" beginning on page 14.

     The SCO board concluded that on balance the potential benefits of the
combination outweighed the potential risks. This discussion of the information
and factors considered by the board is not meant to be exhaustive. Given the
complexity and the number of factors considered, the board did not attempt to
quantify or otherwise assign relative weight to specific factors.

OPINIONS OF FINANCIAL ADVISORS

Opinion of Caldera's Financial Advisor

     Broadview is Caldera's financial advisor. The Caldera board selected
Broadview to act as financial advisor based on Broadview's reputation and
experience in the information technology, communication and media sector and the
telecommunications carrier access equipment industry in particular. In its role
as financial advisor, Broadview was requested to render an opinion to the
Caldera board regarding the fairness from a financial point of view to Caldera
stockholders of the exchange ratio of one share of New Caldera common stock
issued per share of Caldera stock in the merger of Caldera with New Caldera,
which is part of the combination. At the meeting of the Caldera board on July
31, 2000, Broadview delivered its written opinion that, as of July 31, 2000,
based upon and subject to the various factors and assumptions, the exchange
ratio was fair, from a financial point of view, to Caldera stockholders.

     BROADVIEW'S OPINION, WHICH DESCRIBES THE ASSUMPTIONS MADE, MATTERS
CONSIDERED AND LIMITATIONS ON THE REVIEW UNDERTAKEN BY BROADVIEW, IS ATTACHED AS
APPENDIX B TO THIS DOCUMENT. CALDERA STOCKHOLDERS ARE URGED TO, AND SHOULD, READ
THE BROADVIEW OPINION CAREFULLY AND IN ITS ENTIRETY. THE BROADVIEW OPINION IS
DIRECTED TO THE CALDERA BOARD AND ADDRESSES ONLY THE FAIRNESS OF THE
CONSIDERATION PAID TO SCO FOR THE SERVER AND PROFESSIONAL SERVICES GROUPS FROM A
FINANCIAL POINT OF VIEW TO CALDERA AS OF THE DATE OF THE OPINION. THE BROADVIEW
OPINION DOES NOT ADDRESS ANY OTHER ASPECT OF THE TRANSACTION AND DOES NOT
CONSTITUTE A RECOMMENDATION TO ANY HOLDER OF CALDERA COMMON STOCK AS TO HOW TO
VOTE AT THE CALDERA SPECIAL MEETING. THE SUMMARY OF THE BROADVIEW OPINION SET

       to them by Caldera's counsel on July 30, 2000 (which, for the purposes of
       their opinion, Broadview assumed, with Caldera's permission, to be
       identical in all material respects to the reorganization agreement
       executed except that, Broadview assumed with Caldera's permission that

     - conducted other financial studies, analyses and investigations as they
       deemed appropriate for purposes of this opinion.

     The following is a brief summary of some of the sources of information and
valuation methodologies used by Broadview in rendering Broadview's opinion.
These analyses were orally presented to the Caldera board at its meeting on July
31, 2000 and delivered with the opinion on August 10, 2000. This summary
includes the financial analyses used by Broadview and deemed to be material, but
does not purport to be a complete description of analyses performed by Broadview
in arriving at its opinion. Broadview did not explicitly assign any relative
weights to the various factors of analyses considered. This summary of financial
analyses includes information presented in tabular format. In order to fully
understand the financial analyses used by Broadview, the tables must be read
together with the text of each summary. The tables alone do not constitute a
complete description of the financial analyses.

     PUBLIC COMPANY COMPARABLE ANALYSIS -- Broadview considered ratios of market
capitalization, adjusted for cash and debt when necessary, to selected
historical and projected operating results in order to derive multiples placed
on a company in a particular market segment. In order to perform this analysis,
Broadview compared financial information of the server and professional services
groups with publicly available information for the companies competing in the
North American software and related services industry with trailing revenues
between $50 million to $500 million and negative projected December 31, 2000
annual revenue growth. The server and professional services groups Comparable
Index consists of the following companies: Transaction Systems Architects, Inc.;
eShare Communications, Inc.; Pervasive Software, Inc.; Epicor Software
Corporation; AVT Corporation; Brightstar Information Technology Group,

                                       41
<PAGE>   54

Inc.; and Alternative Resources Corporation. For this analysis, as well as other
analyses, Broadview examined publicly available information, as well as a range
of estimates based on securities research analyst reports.

     The following table presents, as of July 28, 2000, the median multiples and
the range of multiples for the server and professional services groups
Comparable Index of total market capitalization (defined as equity market
capitalization plus total debt minus cash and cash equivalents) divided by
selected operating metrics:

</TABLE>

     No company utilized in the public company comparables analysis as a
comparison is identical to the server and professional services group. In
evaluating the comparables, Broadview made numerous assumptions with respect to
software and services industry performance and general economic conditions, many
of which are beyond the control of Caldera. Mathematical analysis, such as
determining the median, average, or range, is not in itself a meaningful method
of using comparable company data.

     TRANSACTION COMPARABLES ANALYSIS -- Broadview considered ratios of equity
purchase price, adjusted for the seller's cash and debt when appropriate, to
selected historical operating results in order to indicate multiples strategic
and financial acquirers have been willing to pay for companies in a particular
market segment. In order to perform this analysis, Broadview reviewed a number
of transactions that they considered similar to the Transaction. Broadview
selected these transactions by choosing transactions from January 1, 2000
through July 28, 2000 involving sellers in the systems management software
industry, with trailing revenues greater than $10 million and less than $200
million. Broadview used multiples derived from the median of the multiples
calculated for the transactions used in valuing the server and professional
services group. For this analysis, as well as other analyses, Broadview examined
publicly available information, as well as information from Broadview's
proprietary database of published and confidential merger and acquisition
transactions in the information technology, communication and media industries.
These transactions consisted of the acquisition of:

     - Ganymede Software Inc. by Mission Critical Software, Inc.;

     - Architel Systems Corporation by Nortel Networks Corporation;

     - AXENT Technologies, Inc. by Symantec Corporation;

     - Vinca Corporation by Legato Systems, Inc.;

     - Confidential by Confidential;

</TABLE>

     No transaction utilized as a comparable in the transaction comparables
analysis is identical to the Transaction. In evaluating the comparables,
Broadview made numerous assumptions with respect to the software and services
industry's performance and general economic conditions, many of which are beyond
the control of Caldera or SCO. Mathematical analysis, such as determining the
average, median, or range, is not in itself a meaningful method of using
comparable transaction data.

     RELATIVE CONTRIBUTION ANALYSIS -- Broadview examined the relative
contribution of the server and professional services groups to Caldera for a
number of historical and projected operating metrics. In this analysis,
projected figures are derived from selected equity analyst reports covering
Caldera and Caldera and SCO management estimates for the server and professional
services group.

     The following reflect the relative contribution of the server and
professional services groups and Caldera for each operating metrics:

     RELATIVE OWNERSHIP ANALYSIS -- A relative ownership analysis measures each
of the merging companies' relative equity ownership and relative entity
ownership (entity ownership compares the relative entity values of the combining
companies; entity value equals equity value minus cash and cash equivalents plus
total debt). At the Caldera ratio defined in the Agreement, the implied equity
ownership is 72.0% for Caldera and 28.0% for the server and professional
services group, while the implied entity ownership is 64.9% for Caldera and
35.1% for the server and professional services group.

     CALDERA STOCK PERFORMANCE ANALYSIS -- Broadview compared the recent stock
performance of Caldera with that of the S&P500 and NASDAQ Composites and the
Caldera Comparable Index. The Caldera Comparable Index is comprised of public
companies that Broadview deemed comparable to Caldera. Broadview selected three
public companies in the Linux-based operating system and application
infrastructure industry.

     The Linux-based operating system and application infrastructure public
companies consist of:
         Red Hat, Inc.;
         Cobalt Networks, Inc.; and
         VA Linux Systems, Inc.

     EVALUATION OF CALDERA EQUITY -- Broadview compared financial information of
Caldera with publicly available information for companies comprising the Caldera
Comparable Index. For this analysis, as well as other analyses, Broadview
examined publicly available information, as well as a range of estimates based
on securities research analyst reports.

     PRO FORMA COMBINATION ANALYSIS -- Broadview calculated the pro forma impact
of the Transaction on the combined entity's projected earnings per share for
Caldera's fiscal year ending October 31, 2001, taking into consideration various
financial effects which will result from consummation of the Transaction.

                                       43
<PAGE>   56

This analysis relies upon certain financial and operating assumptions provided
by equity research analysts and publicly available data about Caldera and
Caldera and SCO management estimates for the server and professional services
group. Broadview examined a purchase scenario under the assumption that no
opportunities for cost savings or revenue enhancements exist. Based on this
scenario, the pro forma pooling model indicates EPS accretion excluding
acquisition expenses, purchased R&D write-off, goodwill, and foregone interest,
for the fiscal year ending October 31, 2001.

     CONSIDERATION OF THE DISCOUNTED CASH FLOW METHODOLOGY -- While discounted
cash flow is a commonly used valuation methodology, Broadview did not employ
such an analysis for the purposes of this opinion. Discounted cash flow analysis
is most appropriate for companies that exhibit relatively steady or somewhat
predictable streams of future cash flow. For a business such as the server and
professional services group, a preponderance of the value in a valuation based
on discounted cash flow will be in the terminal value of the entity, which is
extremely sensitive to assumptions about the sustainable long-term growth rate
of the company. Given the uncertainty in estimating both the future cash flows
and a sustainable long-term growth rate for Caldera, Broadview considered a
discounted cash flow analysis inappropriate for valuing the server and
professional services group.

     In connection with the review of the Transaction by the Caldera board,
Broadview performed a variety of financial and comparative analyses. The summary
set forth above does not purport to be a complete description of the analyses
performed by Broadview in connection with the Transaction.

     The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to partial analysis or summary description. In arriving
at its opinion, Broadview considered the results of all of its analyses as a
whole and did not attribute any particular weight to any analysis or factor
considered by it. Furthermore, Broadview believes that selecting any portion of
its analyses, without considering all analyses, would create an incomplete view
of the process underlying its opinion.

     In performing its analyses, Broadview made numerous assumptions with
respect to industry performance and general business and economic conditions and
other matters, many of which are beyond the control of Caldera or SCO. The
analyses performed by Broadview are not necessarily indicative of actual values
or actual future results, which may be significantly more or less favorable than
suggested by such analyses. The Caldera Ratio pursuant to the Agreement and
other terms of the Agreement were determined through arm's length negotiations
between Caldera and SCO, and were approved by the Caldera board. Broadview
provided advice to the Caldera board during such negotiations; however,
Broadview did not recommend any specific consideration to the Caldera board or
that any specific consideration constituted the only appropriate consideration
for the Transaction. In addition, Broadview's opinion and presentation to the
Caldera board was one of many factors taken into consideration by the Caldera
board in making its decision to approve the Transaction. Consequently, the
Broadview analyses as described above should not be viewed as determinative of
the opinion of the Caldera board with respect to the value of the server and
professional services groups or of whether the Caldera board would have been
willing to agree to a different consideration.

     Upon consummation of the Transaction, Caldera will be obligated to pay
Broadview a transaction fee of approximately $2.0 million. The monthly retainer
fees and the fairness opinion fee will be credited against the transaction fee
payable by Caldera upon completion of the Transaction. In addition, Caldera has
agreed to reimburse Broadview for its reasonable expenses, including fees and
expenses of its counsel, and to indemnify Broadview and its affiliates against
certain liabilities and expenses related to their engagement, including
liabilities under the federal securities laws. The terms of the fee arrangement
with Broadview, which Caldera and Broadview believe are customary in
transactions of this nature, were negotiated at arm's length between Caldera and
Broadview, and the Caldera Board was aware of the nature of the fee arrangement,
including the fact that a significant portion of the fees payable to Broadview
is contingent upon completion of the Transaction.

OPINION OF SCO FINANCIAL ADVISOR

     SCO engaged Chase H&Q, a division of Chase Securities Inc., to act as an
exclusive financial advisor to SCO in connection with the proposed merger
combination. The SCO board of directors selected Chase H&Q to act as an
exclusive financial advisor based on Chase H&Q's qualifications, expertise and
reputation, as well as Chase H&Q's historic investment banking relationship and
familiarity with SCO. Chase H&Q delivered its oral opinion on July 31, 2000,
subsequently confirmed in writing, to the SCO board of directors that, as of
such date, based upon and subject to the assumptions made, matters considered
and limits of the review undertaken by Chase H&Q, the consideration to be
received by SCO in connection with the proposed combination was fair from a
financial point of view, to SCO.

     THE FULL TEXT OF THE OPINION DELIVERED BY CHASE H&Q TO THE SCO BOARD OF
DIRECTORS, DATED AUGUST 1, 2000, WHICH SETS FORTH THE ASSUMPTIONS MADE, GENERAL
PROCEDURES FOLLOWED, MATTERS CONSIDERED AND LIMITATIONS ON THE SCOPE OF REVIEW
UNDERTAKEN BY CHASE H&Q IN RENDERING ITS OPINION, IS ATTACHED AS APPENDIX C TO
THIS JOINT PROXY STATEMENT/PROSPECTUS AND IS INCORPORATED HEREIN BY REFERENCE.
THE CHASE H&Q OPINION DOES NOT CONSTITUTE A RECOMMENDATION TO ANY SCO
SHAREHOLDER AS TO HOW SUCH SHAREHOLDER SHOULD VOTE WITH RESPECT TO THE
REORGANIZATION AGREEMENT. THE SUMMARY OF THE CHASE H&Q OPINION SET FORTH BELOW
IS QUALIFIED IN ITS ENTIRETY BY REFERENCE TO THE FULL TEXT OF SUCH OPINION
ATTACHED HERETO AS APPENDIX C. SCO SHAREHOLDERS ARE URGED TO READ THE OPINION
CAREFULLY IN ITS ENTIRETY.

     In reviewing the proposed transaction, and in arriving at its opinion,
Chase H&Q, among other things:

(i)      reviewed the publicly available consolidated financial statements of
         Caldera for recent years and interim periods to date and certain other
         relevant financial and operating data of Caldera (including its capital
         structure) made available to them from published sources;

(ii)     reviewed certain publicly available projected financial and operating
         information relating to Caldera;

(iii)    discussed the business, financial condition and prospects of Caldera
         with certain members of senior management;

     Chase H&Q did not assume responsibility for independent verification of,
and did not independently verify, any of the information concerning the
Contributed Companies or Caldera considered in connection with its review of the
proposed combination, including without limitation any financial information,
forecasts or projections, considered in connection with the rendering of its
opinion. Accordingly, for purposes of its opinion, Chase H&Q assumed and relied
upon the accuracy and completeness of all such information. In connection with
its opinion, Chase H&Q did not prepare or obtain any independent valuation or
appraisal of any of the assets or liabilities of the Contributed Companies or
Caldera, and it did not conduct a physical inspection of the properties and
facilities of the Contributed Companies or Caldera. With respect to the
financial forecasts and projections relating to the Contributed Companies,
prepared by SCO management, Chase H&Q assumed that they reflected the best
currently available estimates and judgments of the expected future financial
performance of the Contributed Companies and Chase H&Q expressed no view as to
the reasonableness of such forecasts and projections or the assumptions on which
such forecasts or projections were based. For the purposes of its opinion, Chase
H&Q also assumed that neither the Contributed Companies nor Caldera was a party
to any pending transactions, including without limitation external
recapitalizations or material merger or acquisition discussions, other than the
proposed merger and transactions in the ordinary course of conducting their
respective businesses. SCO advised Chase H&Q, and for purposes of its opinion
Chase H&Q assumed, that (i) the combination will qualify as a tax-free
reorganization for New Caldera and Caldera under the Internal Revenue Code, (ii)
the Contribution will qualify as a nonrecognition transfer for SCO and New
Caldera under the Internal Revenue Code, and (iii) the proposed combination
would be treated as a purchase for financial accounting purposes.

     In performing its analyses, Chase H&Q used financial forecasts and
projections prepared by SCO management for the Contributed Companies and
published research analyst estimates of financial performance of Caldera which
are based on numerous assumptions with respect to industry performance, general
business and economic conditions and other matters, many of which are beyond the
control of SCO, Caldera or Chase H&Q. The analyses performed by Chase H&Q and
summarized below are not necessarily indicative of actual values or actual
future results, which may be significantly more or less favorable than suggested
by such analyses. Because such analyses are inherently subject to uncertainty,
being based upon numerous factors or events beyond the control of SCO, Caldera
or their respective advisors, neither SCO, Chase H&Q nor any other person
assumes responsibility if future results or actual values are materially
different from the results of analyses based on forecasts or assumptions.
Additionally, analyses relating to the values of businesses do not purport to be
appraisals or to reflect the prices at which businesses or securities actually
may be acquired or bought or sold.

     Chase H&Q's opinion is necessarily based upon market, economic, financial
and other conditions as they existed and can be evaluated as of the date of the
opinion and any subsequent change in such conditions would require a
reevaluation of such opinion. Although subsequent developments may affect its
opinion, Chase H&Q has assumed no obligation to update, revise or reaffirm it.

     The preparation of a fairness opinion is a complex process and is not
necessarily susceptible to summary description. The summary of Chase H&Q's
analyses set forth below summarizes the material analyses presented to the SCO
board of directors but is not a complete description of the presentation by
Chase H&Q to the SCO board of directors or the analysis performed by Chase H&Q
in connection with preparing its opinion. In arriving at its opinion, Chase H&Q
did not attribute any particular weight to any analyses or factors considered by
it, but rather made subjective, qualitative judgments as to the significance and
relevance of each analysis and factor. Accordingly, Chase H&Q believes that its
analyses and the summary set forth below must be considered as a whole and that
selecting portions of its analyses, without considering all analyses, or of the
following summary, without considering all factors and analyses, could create an
incomplete view of the processes underlying the analyses set forth in the Chase
H&Q presentation to the SCO board of directors and Chase H&Q's opinion.

     The terms of the proposed merger were determined through negotiations
between SCO and Caldera and were approved by the SCO board of directors.
Although Chase H&Q provided advice to SCO during the course of these
negotiations, the decision to enter into the merger was solely that of the SCO
board of
                                       46

directors. As described above, the opinion of Chase H&Q and its presentation to
the SCO board of directors were only one of a number of factors taken into
consideration by the SCO board of directors in making its determination to
approve the Proposed Transaction.

     The following is a brief summary of the material financial analyses
performed by Chase H&Q in connection with providing its opinion to the SCO board
of directors on July 31, 2000. The summary includes information presented in
tabular format. You should read these tables together with the text of each
summary, because the tables alone are not a complete description of the
financial analysis.

     Comparable Publicly Traded Companies Analysis.  This analysis reviews a
business' operating performance and outlook relative to a group of peer
companies to determine an implied value. Using publicly available research
analyst estimates, Chase H&Q compared, among other things, the enterprise values
and projected revenues for calendar years 2000 and 2001 for the SCO Server
Business to corresponding measures for certain publicly traded companies that
Chase H&Q considered comparable.

The companies that Chase H&Q considered comparable were:

     - NEON Systems, Inc.;

     - BMC Software, Inc.;

     - Computer Associates International Inc.;

     - Compuware Corporation;

     - Novell Inc.;

     - Informix Corp.;

     - Progress Software Corp.;

     - Sapiens International Corp.;

     - Inprise Corporation; and

     - Sybase, Inc.

     Chase H&Q determined enterprise value to revenue multiples for these
companies. Enterprise value is defined as the share price multiplied by the
diluted shares outstanding plus debt and minority interest less cash. Applying
ranges of such multiples for the comparable companies to projected calendar year
2000 and 2001 revenues of the SCO Server Business resulted in an enterprise
value range for the SCO Server Business from which Chase H&Q subtracted the
present value of the estimated after-tax cash flow of the Open Server product
based on SCO management projections, as described below, and added the estimated
valuation range of the SCO Professional Services, as described below, to derive
a value for the Contributed Companies. The following table summarizes the
analysis:

     Chase H&Q compared these results to the proposed transaction value of $119

     Precedent Transactions Analysis.  This analysis provides a valuation range
based on financial information of selected public companies that have been
recently acquired and are in similar industries as the business being evaluated.
Using publicly available research analyst estimates, Chase H&Q compared the
proposed merger with seven selected mergers and acquisitions transactions
involving companies in the software industry. The acquirors and targets in the
transactions that Chase H&Q deemed comparable to the proposed merger were:

     - Compuware Corporation/Viasoft, Inc.;

     - Sterling Software Inc./Interlink Computer Sciences Inc.;

     - Sterling Software Inc./Information Advantage, Inc.;

     - Invensys plc/Marcam Solutions, Inc.;

     - Cadence Design Systems Inc./OrCAD Inc.;

     - Activision Inc./Expert Software, Inc.; and

     - Ardent Software Inc./Prism Solutions, Inc.

     In examining these transactions, Chase H&Q analyzed, among other things,
the multiples of transaction values, defined as the offer price per share
multiplied by the diluted shares outstanding plus debt and minority interest
less cash for the most recent balance sheet prior to the announcement of the
transaction, to (1) revenues of the target for the last four fiscal quarters
preceding the public announcement of the transaction and (2) projected revenues
of the target for the calendar year following the public announcement of the
transaction. All multiples for the selected transactions were based on public
information available at the time of public announcement, and Chase H&Q's
analysis did not take into account different market and other conditions during
the two-year period during which the selected transactions occurred. Applying
ranges of such multiples for the precedent transactions to projected calendar
year 2000 and 2001 revenues of the SCO Server Business resulted in an enterprise
value range for the SCO Server Business from which Chase H&Q subtracted the
present value of the estimated after-tax cash flow of the Open Server product
based on SCO management projections, as described below, and added the estimated
valuation range of the SCO Professional Services, as described below, to derive
a value for the Contributed Companies. The following table summarizes the
analysis:

cash.

     Chase H&Q observed that no company used in the above analyses is identical
to SCO and the circumstances surrounding each of the companies are inherently
different. Accordingly, an analysis of the results of the foregoing is not
mathematical; rather it involves complex, qualitative considerations and
judgments, reflected in Chase H&Q's opinion, concerning differences in the
financial and operating characteristics of the compared companies and other
factors that could affect the public trading values of the comparable companies
and Caldera.

     Discounted Cash Flow Analysis.  This analysis calculates an implied value
based on the present value of the future cash flow from the Contributed
Companies. Chase H&Q performed a discounted cash flow analysis of the server
business based upon certain forecast and projection information provided to
Chase H&Q by the management of SCO for the years ending September 30, 2001
through 2003. Utilizing such information, Chase H&Q calculated a range of values
based upon the discounted present value of the sum of the projected stream of
unlevered free cash flows, defined as EBITDA less taxes less the change in
working capital less capital expenditures, to the SCO server business from
September 30, 2001 through September 30, 2003 and the projected terminal value
of the SCO server business at September 30, 2003 based upon a range of forward
revenue multiples applied to projected revenues in 2004. Chase H&Q calculated a
range of enterprise values of the SCO server business as of September 30, 2000
based on discount rates of 12.5%, 13.5% and 14.5% and on 2004 forward revenue
terminal multiples of 0.8x, 1.2x and 1.6x. The analysis resulted in an implied
enterprise value for the SCO server business from which Chase H&Q subtracted the
present value of the estimated after-tax cash flow of the Open Server product
based on SCO management projections, as described below, and added the estimated
valuation range of the SCO Professional Services, as described below, to derive
a value for the Contributed Companies. The following table summarizes the

     Chase H&Q compared these results to the proposed transaction value of $119

     Other Analysis.  Chase H&Q also performed, among other analyses, a present
value analysis of future Open Server Product cash flow and a comparable public
companies analysis of the SCO Professional Services Business which were used in
conjunction with the foregoing methods of analysis to derive valuation ranges
for the Contributed Companies.

     Present Value of Open Server Product Cash Flow.  This analysis calculates a
theoretical value based on the present value of future cash flow. Chase H&Q
performed a discounted cash flow analysis of the Open Server Product based upon
certain forecast and projection information provided to Chase H&Q by the
management of SCO for the years ending September 30, 2001 through 2003.
Utilizing such information, Chase H&Q calculated a range of values based upon
the discounted present value of the sum of the projected stream of unlevered
free cash flows, defined as EBITDA less taxes less the change in working capital
less capital expenditures, of the Open Server Product from September 30, 2001
through September 30, 2003 and the projected terminal value of the Open Server
Product at September 30, 2003 based upon the agreed upon buyout option of 3.0x
revenues. Chase H&Q calculated a range of enterprise values of the Open Server
Product as of September 30, 2000 based on discount rates of 12.5%, 13.5% and
14.5%. The analysis resulted in an implied enterprise value for the Open Server
Product of $48 million to $50 million.

     Comparable Publicly Traded Professional Services Companies Analysis.  This
analysis reviews a business' operating performance and outlook relative to a
group of peer companies to determine an implied value. Using publicly available
research analyst estimates, Chase H&Q compared, among other things, the
enterprise values and projected revenues for calendar years 2000 and 2001 for
the SCO Professional Services Business to corresponding measures for certain
publicly traded companies that Chase H&Q considered comparable.

                                       49
<PAGE>   62

     The companies that Chase H&Q considered comparable were:

     - AnswerThink Inc.;

     - Complete Business Solutions, Inc.;

     - MarchFIRST, Inc.; and

     - Syntel, Inc.

     Chase H&Q determined enterprise value to revenue multiples for these
companies. Applying ranges of such multiples for the comparable companies to
projected calendar year 2000 and 2001 revenues of the SCO Professional Services
Business resulted in a range of implied enterprise value of $5 million to $10
million.

     The foregoing description of Chase H&Q's opinion is qualified in its
entirety by reference to the full text of such opinion that is attached as
Appendix C to this joint proxy statement/prospectus statement.

     Chase H&Q, as part of its investment banking services, is regularly engaged
in the valuation of businesses and their securities in connection with mergers
and acquisitions, strategic transactions, corporate restructurings, negotiated
underwritings, secondary distributions of listed and unlisted securities,
private placements and valuations for corporate and other purposes. In the past,
we have provided investment banking and other financial advisory services to SCO
and have received fees for rendering these services.

     Pursuant to an engagement letter with Chase H&Q, SCO has agreed to pay
Chase H&Q a customary fee in connection with the financial advisory services
provided by Chase H&Q and the delivery of the fairness opinion. SCO also agreed
to reimburse Chase H&Q for its reasonable out-of-pocket expenses and to
indemnify Chase H&Q against certain liabilities, including liabilities under the
federal securities laws or relating to or arising out of Chase H&Q's engagement
as financial advisor.

STRUCTURE OF THE COMBINATION

The Caldera merger

     A wholly owned subsidiary of New Caldera will merge with and into Caldera,
Caldera will survive the merger and become a wholly owned subsidiary of New
Caldera. Caldera stockholders will become stockholders of New Caldera.

The contribution of the server and professional services groups

     SCO will contribute the capital stock of the contributed companies, and SCO
and some of its subsidiaries will contribute to New Caldera the contributed
assets. The contributed assets and the contributed companies will be owned by
New Caldera.

     "Contributed companies" means The Santa Cruz Operation Limited, The Santa
Cruz Operation (France) SARL, The Santa Cruz Operation (Deutschland) GmbH, The
Santa Cruz Operation (Italia) Srl, The Santa Cruz Operation Pty. Limited, SCO
Canada, CO, The Santa Cruz Operation de Mexico, S.De R.L. De C. V., The Santa
Cruz Operation (Asia) Ltd, SCO Foreign Sales Corporation, SCO, Kabushiki Kaisha,
The Santa Cruz Operation Latin America, Inc., Nihon SCO Limited, SCO do Brazil
Limitada, SCO Software (China) Company, Ltd., and Unix System Technologies China
Company, Ltd. (USTC).

     "Contributed assets" means, subject to exceptions, (1) the assets listed on
certain schedules to the reorganization agreement, (2) intellectual property
rights material to the products of the server and professional services groups,
and (3) assets used in the server and professional groups.

     "Contributing companies" means SCO and certain other subsidiaries of SCO.

     As a result of the transfer to New Caldera of the capital stock of the
contributed companies, New Caldera will own all of the outstanding equity
capital of the contributed companies, each of which will

                                       50
<PAGE>   63

remain liable for their existing liabilities. In addition, New Caldera will not
acquire the accounts receivables nor will it assume certain accounts payables
and other liabilities of the server and professional services groups. New
Caldera shall assume, however, the following liabilities relating to the server
and professional services groups business:

     - all liabilities of the contributing companies under all contracts
       contributed as part of the contributed assets;

     - all liabilities of the contributing companies that are included in a
       closing group account for the server and professional services groups as
       of the closing date; and

     - identified tax liabilities including those taxes attributable to the
       operations of the contributed companies after the closing date.

     Except for the liabilities of the contributed companies and their
subsidiaries, which will remain the sole responsibility of the applicable
contributed company, and the assumed liabilities described above, New Caldera
will not assume or otherwise have any obligation for any liabilities of SCO.

     SCO has agreed to take all actions reasonably necessary to fully transfer
to New Caldera the capital stock of the contributed companies and the
contributed assets held by them or their subsidiaries and any contributed
contracts to which they are a party.

RESTRICTIONS ON RESALE OF NEW CALDERA COMMON STOCK

     The shares of New Caldera common stock to be issued in the reorganization
will have been registered under the Securities Act. These shares will be freely
transferable without restriction, except for shares received by SCO or by any
person who is an "affiliate" of either of us. Shares held by these affiliates
may be resold by them only in transactions permitted by the resale provisions of
Rule 145 or Rule 144 in the case of persons who become affiliates of New
Caldera. Persons who may be deemed to be affiliates of Caldera, SCO or New
Caldera generally include individuals or entities that control, are controlled
by, or are under common control with, that party and may include certain
officers and directors of such party as well as principal stockholders of that
party.

     Pursuant to the reorganization agreement, SCO shall be able to distribute
its shares of New Caldera common stock to its shareholders six (6) months from
the closing date; provided, however, that SCO cannot sell more than 25% of its
shares of New Caldera in a six (6) month period.

     New Caldera and SCO will enter into the stockholder agreement. This
agreement provides that, so long as SCO owns 10% of the outstanding stock of New
Caldera, it may not sell shares of New Caldera common stock to any person or
group holding five percent (5%) or more of New Caldera common stock without the
consent of New Caldera.

RESALE OF SHARES ISSUED UNDER THE CALDERA OPTION PLANS

     New Caldera will be required to file with the Securities and Exchange
Commission a registration statement for the shares of New Caldera common stock
issuable upon exercise of the New Caldera stock options issued in the exchange
offer no later than the 10th day after the closing of the combination.

NASDAQ LISTING

     We expect that the New Caldera common stock will be traded on the Nasdaq
National Market under the symbol "CALD."

     It is a condition to the closing of the combination that the shares of New
Caldera common stock to be issued to SCO be approved for listing on the Nasdaq
National Market, subject to official notice of issuance.

MATERIAL UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS OF THE COMBINATION

     The following discussion summarizes the material federal income tax
considerations relevant to the exchange of shares of Caldera common stock for
New Caldera common stock pursuant to the combination that are generally
applicable to holders of Caldera common stock, and the material federal income
tax considerations relevant to SCO's exchange of assets for New Caldera common
stock. This discussion is based on currently existing provisions of the Internal
Revenue Code (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 Caldera stockholders and to SCO as described herein.

     The Caldera stockholders should be aware that this discussion does not deal
with all federal income tax considerations that may be relevant to particular
Caldera stockholders in light of their particular circumstances. For example,
different rules may apply to dealers in securities, persons subject to the
alternative minimum tax provisions of the Code, foreign persons, persons who do
not hold their Caldera common stock as capital assets, or persons who acquired
their shares in connection with stock option or stock purchase plans or in other
compensatory transactions. In addition, the following discussion does not
address the tax consequences of the combination under foreign, state or local
tax laws, the tax consequences of transactions effectuated prior or subsequent
to, or concurrently with, the combination (whether or not any such transactions
are undertaken in connection with the combination), including without limitation
any transaction in which shares of Caldera common stock are acquired or shares
of New Caldera common stock are disposed of, or the tax consequences of the
assumption by New Caldera of Caldera or SCO options or warrants. Accordingly,
CALDERA STOCKHOLDERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS AS TO THE
SPECIFIC TAX CONSEQUENCES TO THEM OF THE COMBINATION, INCLUDING THE APPLICABLE
FEDERAL, STATE, LOCAL AND FOREIGN TAX CONSEQUENCES.

Material Federal Income Tax Considerations of the Combination to the Caldera
Stockholders

     As to Caldera and its stockholders, the combination is intended to
constitute an exchange described in Section 351 of the Code as well as a
"reorganization" within the meaning of Section 368 of the Code. Provided that
the combination does so qualify as either an exchange under Section 351 or a
"reorganization," then, subject to the limitations and qualifications referred
to herein, the combination will generally result in the following federal income
tax consequences to the Caldera stockholders:

     - No gain or loss will be recognized by holders of Caldera common stock
       solely upon their receipt of New Caldera common stock in exchange for
       Caldera common stock in the combination;

     - The aggregate tax basis of the New Caldera common stock received by
       Caldera stockholders in the combination will be the same as the aggregate
       tax basis of the Caldera common stock surrendered in exchange therefor;
       and

     - The holding period of the New Caldera common stock received by each
       Caldera stockholder in the combination will include the period for which
       the Caldera common stock surrendered in exchange therefor was considered
       to be held, provided that the Caldera common stock so surrendered is held
       as a capital asset at the time of the combination.

Material Federal Income Considerations of the Combination to the SCO
Shareholders

     As to SCO, the combination is intended to constitute an exchange within the
meaning of Section 351 of the Code. Provided that the combination does so
qualify, then, subject to the limitations and qualifications referred to herein,
the combination will result in the following federal income tax consequences to
SCO:

     - SCO will recognize gain with respect to the cash and other non-stock
       consideration, if any, received by SCO in partial consideration for SCO's
       contribution of assets to New Caldera. For purposes of

                                       52
<PAGE>   65

determining the amount of gain recognized by SCO, the non-stock consideration
received by SCO from New Caldera will be allocated among the assets contributed
by SCO to New Caldera in proportion to their relative fair market values. SCO
      will not recognize any loss for federal income tax purposes with respect
      to any contributed asset;

     - No gain or loss will be recognized by SCO upon SCO's receipt of New
       Caldera common stock in exchange for assets contributed by SCO to New
       Caldera; and

     - The aggregate tax basis of the New Caldera common stock received by SCO
       in the combination will be the same as the aggregate tax basis of the
       assets surrendered in exchange therefor.

     The parties are not requesting and will not request a ruling from the IRS
in connection with the combination. The consummation of the combination is
conditioned on the receipt by Caldera of a tax opinion from Brobeck, Phleger &
Harrison LLP that the combination will constitute a "reorganization" described
in Section 368 of the Code and the receipt by SCO of an opinion from Wilson
Sonsini Goodrich & Rosati Professional Corporation to the effect that the
combination will constitute a transaction described in Section 351 of the Code.
Caldera stockholders and SCO shareholders should be aware that the tax opinions
do not bind the IRS and the IRS is therefore not precluded from successfully
asserting a contrary opinion. The tax opinions will be subject to certain
assumptions and qualifications, including but not limited to the truth and
accuracy of certain representations made by New Caldera, Caldera, SCO and
certain Caldera stockholders.

     A successful IRS challenge to tax treatment of the combination would result
in Caldera stockholders and SCO recognizing taxable gain or loss with respect to
each share of common stock of Caldera surrendered equal to the difference
between the stockholder's or SCO's basis in such share and the fair market
value, as of the effective time, of the New Caldera common stock received in
exchange therefor. In such event, a stockholder's or SCO's aggregate basis in
the New Caldera common stock so received would equal its fair market value, and
the stockholder's or SCO's holding period for such stock would begin the day
after the combination.

ACCOUNTING TREATMENT

Accounting treatment by New Caldera

     The combination will be accounted for under the purchase method of
accounting. The purchase price of the contributed assets, or the aggregate
merger consideration, including direct costs of the combination, will be
allocated to the assets acquired, including in-process research and development,
and liabilities assumed based upon their estimated fair values. The excess
purchase consideration will be allocated to goodwill.

     After the combination, the results of New Caldera's operations will include
the results of operations of Caldera and the server and professional services
group.

     The combination and the resulting conversion of Caldera common stock into
New Caldera common stock will be treated as a reorganization with no change in
the recorded amount of Caldera's assets and liabilities. The financial
statements of Caldera will become the financial statements of New Caldera upon
the closing of the combination.

Accounting treatment by SCO

     The combination will be accounted for as a proportional sale of the net
assets of the server and professional services group. As SCO will retain a 29.5%
interest (based on New Caldera's outstanding shares as of September 1, 2000) SCO
will record a gain equal to 70.5% of the fair value of the New Caldera stock
received by SCO less 70.5% of SCO's basis in the net assets of the server and
professional services group plus cash consideration net of expenses.

     Subsequent to the combination, SCO will include in its financial results
its share of the net income or loss of New Caldera based upon the percentage of
outstanding shares of New Caldera owned by SCO
                                       53
<PAGE>   66

adjusted for the difference in the carrying amount of SCO's investment in New
Caldera and its proportional share of the net income or loss of New Caldera.

     The SCO unaudited pro forma statements beginning on page P-11 are based
upon certain assumptions. The ultimate pro rata gain to be recognized by SCO is
dependent upon the same factors described above for New Caldera. As a result of
these factors, the actual gain and related difference between SCO's investment
in New Caldera and its proportional share of New Caldera's net assets may differ
materially from the amounts assumed in the SCO unaudited pro forma statements.

GOVERNMENTAL AND REGULATORY APPROVALS

     The combination may not be completed until notifications have been given
and certain information has been furnished to the Federal Trade Commission and
the Antitrust Division of the United States Justice Department and specified
waiting period requirements under the Hart-Scott-Rodino Antitrust Improvements
Act, or the HSR Act, have been satisfied. All required filings under the HSR Act
have been made and the waiting periods for the filings have expired.

     The FTC and the Antitrust Division frequently scrutinize the legality under
the antitrust laws of the transactions such as the combination. Despite the
expiration of the waiting periods under the HSR Act, at any time before or after
the completion of the combination, the Federal Trade Commission, the antitrust
division, state attorneys general or others could take action under antitrust
laws. These actions could include seeking to enjoin the combination, seeking to
cause the divestiture of significant assets of Caldera or SCO or seeking to
impose conditions on New Caldera with respect to the business operations of the
combined companies. If a challenge is made, we may not prevail or we may be
required to terminate the reorganization agreement, to divest assets, to license
proprietary technology to third parties or accept conditions in order to
complete the combination.

DISSENTERS' OR APPRAISAL RIGHTS

     Caldera stockholders are not entitled to dissenters' or appraisal rights
with respect to the combination.

     If holders of 5% or more of the outstanding shares of SCO common stock
entitled to vote at the SCO special meeting vote against the reorganization
agreement and comply with certain other procedures specified in Chapter 13 of
the California Corporations Code, SCO shareholders of record who take such
actions will be entitled to exercise dissenters' rights. In accordance with the
provisions of Chapter 13 of the California Corporations Code, dissenting SCO
shareholders will have the right to be paid in cash the fair market value of
their shares of SCO common stock, determined as of the day before the first
announcement of the combination, and excluding any appreciation or depreciation
as a result of the combination.

     In order to exercise dissenters' rights, dissenting SCO shareholders must
comply with the procedural requirements of Chapter 13 of the California
Corporations Code, a description of which is included here and the full text of
which is attached to this document as Appendix J and is incorporated by
reference in its entirety to this discussion. SCO shareholders wishing to
exercise dissenters' rights are advised to read Chapter 13 of the California
Corporations Code carefully. The failure of a dissenting SCO shareholder to
timely and properly comply with such procedures will result in the termination
or waiver of such rights.

     DISSENTERS' RIGHTS CANNOT BE VALIDLY EXERCISED BY PERSONS OTHER THAN
SHAREHOLDERS OF RECORD REGARDLESS OF THE BENEFICIAL OWNERSHIP OF THE SHARES.
Persons who are beneficial owners of shares held of record by another person,
such as brokers, banks or nominees, should instruct the record holder to follow
the procedures outlined below if they wish to dissent from the combination with
respect to any or all of their shares.

     Dissenting SCO shareholders must submit a written demand to SCO that it
purchase for cash some or all of their shares. The demand must:

     - contain the number and class of the shares held of record by the
       shareholder which the shareholder demands that SCO purchase; and

                                       54
<PAGE>   67

     - 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 of short-form combination.

That statement of fair market value will constitute an offer by the dissenting
SCO shareholder to sell such shares at that price. The demand must be received
by SCO or its transfer agent not later than the date of the special meeting to
vote upon the reorganization, or           , 2000 in the present instance. All
written demands for purchase of SCO shares should be sent or delivered to The
Santa Cruz Operation, Inc. at 425 Encinal Street, Santa Cruz, California 94043,
Attention: Steven Sabbath. SUCH DEMAND WILL NOT BE EFFECTIVE UNLESS IT IS
RECEIVED NO LATER THAN THE DATE OF THE SCO SPECIAL MEETING.

     If SCO shareholders have a right to require SCO to purchase their shares
for cash under the dissenters' rights provisions of the California Corporations
Code, SCO will mail to each such shareholder a notice of approval of the
combination within ten days after the date of shareholder approval, stating the
price determined by it 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 such dissenters' rights. The statement of price
will constitute an offer to purchase any dissenting shares at that price.

     To perfect their dissenters' rights, shareholders of record must:

     - make written demand for the purchase of their dissenting shares upon SCO
       on or before the date of the SCO special meeting;

     - vote their shares against adoption and approval of the reorganization
       agreement; and

     - within 30 days after the mailing to shareholders by SCO of the notice of
       approval of the principal terms of the combination, submit the
       certificate(s) representing their dissenting shares to SCO or its
       transfer agent for notation thereon that they represent dissenting
       shares.

The notice of approval of the combination will specify the date by which the
submission of certificates for endorsement must be made and a submission made
after that date will not be effective for any purpose. Failure to follow any of
these procedures may result in the loss of statutory dissenters' rights.

     If a dissenting SCO shareholder and SCO agree that shares are dissenting
shares and agree upon the price of the shares, SCO, upon surrender of the
certificates, will make payment of that amount (plus interest thereon at the
legal rate on judgments from the date of such agreement) within 30 days after
such agreement. Any agreement between dissenting SCO shareholders and SCO fixing
the "fair market value" of any dissenting shares must be filed with the
Secretary of SCO.

     If SCO denies that the shares are dissenting shares, or SCO and a
dissenting shareholder fail to agree upon the "fair market value" of the shares,
the dissenting SCO shareholder may, within six months after the date on which
notice of approval of the combination was mailed to the shareholder, but not
thereafter, file a complaint in the Superior Court of the proper county. A
dissenting SCO shareholder must bring such an action within six months after the
date on which the notice of approval of the reorganization agreement was mailed
to the shareholder, whether or not SCO responds within such time to the
shareholder's written demand that SCO purchase for cash shares voted against the
reorganization agreement. If such a complaint is timely filed, the court shall
determine whether the shares constitute dissenting shares, and may either
determine or appoint an appraiser to determine the fair market value of the
shares. If the court finds the report of the appraiser reasonable, the court may
confirm the report. The fair market value of the shares will be determined
excluding any appreciation or depreciation in consequence of the combination,
and will be awarded to the dissenting SCO shareholder, together with a fair rate
of interest, if any, to be paid upon the amount determined to be the fair market
value. The costs of the action may be determined by the court and taxed upon the
parties as the court deems equitable, but SCO shall pay such costs if the fair
market value of the shares as determined by the court exceeds the price offered
pursuant to its notice of approval.

                    INTERESTS OF PERSONS IN THE COMBINATION

     In considering the recommendations of the board of directors of Caldera and
SCO with respect to the reorganization agreement, stockholders of Caldera and
shareholders of SCO should be aware that certain executive officers and
directors have some interests in the combination that may be different from or
in addition to, the interests of stockholders of Caldera and shareholders of SCO
generally. The boards of directors were each aware of these interests and
considered them, among other matters, in making its recommendations. These
interests are described below.

     Employment with Caldera.  Each of Caldera's executive officers will have
positions with New Caldera, and each of the current directors of Caldera will
become directors of New Caldera.

     All of the Caldera executive officers and the following executive officers
of SCO: David McCrabb, Senior Vice President and President, Server Division;
Jack Moyer, Senior Vice President, Human Resources; and James Wilt, Senior Vice
President and President, Professional Services Division, will become executive
officers of New Caldera. Further, these individuals will execute employment
agreements with New Caldera that will provide for terms of employment and
severance benefits, among other things. See "Agreements Related to the
Combination -- Employment Agreements."

     SCO Change of Control Agreements.  SCO's board of directors has resolved to
amend the change of control agreements with certain executive officers of SCO,
including those executive officers who will become executive officers of New
Caldera. The amended agreements will provide for:

     - the full acceleration of vesting provisions on all options issued and
       outstanding prior to August 1, 2000 held by each executive officer;

     - an extension of the option term on options issued to those individuals
       who will become executive officers of New Caldera until January 31, 2002;

     - and an extension of the option term, in the case of options held by those
       executive officers staying with SCO, if such individuals are
       involuntarily terminated or terminated by mutual consent, such that
       options held by those individuals will expire in no event sooner than
       January 31, 2002; and

     - a cash payment payable in one year from the date of the closing of the
       combination, provided that such executive officer has not voluntarily
       terminated his employment with SCO or New Caldera, as the case may be,
       equal to: that individual's current annual salary and 100% of his target
       bonus, together with 8.5% interest from the date of the closing of the
       combination.

     Accordingly, the following individuals will receive vesting acceleration on
options granted prior to August 1, 2000, and potential acceleration and cash
payments as follows:

     - Doug Michels, President and Chief Executive Officer -- $601,836;

     - Randall Bresee, Senior Vice President and Chief Financial
       Officer -- $334,180;

     - Michael Orr, Senior Vice President and President of Tarantella
       Division -- $390,193;

     - Steven M. Sabbath, Senior Vice President, Law and Corporate Affairs, and
       Secretary, -- $350,923;

     - Geoff Seabrook, Senior Vice President, Corporate Development -- $267,873;

     - David McCrabb, Senior Vice President and President, Server Software
       Division -- $398,224;

     - Jack Moyer, Senior Vice President, Human Resources -- $320,658; and

     - James Wilt, Senior Vice President and Vice President, Professional
       Services Division -- $353,855.

     SCO Stay Home Options.  On August 1, 2000, the compensation committee of
the SCO board granted options to purchase SCO common stock to certain executive
officers to encourage those individuals to remain with SCO following the
combination. All options shall vest over four years, which may accelerate in the
event of another change of control, and are exercisable at $3.125 per share, the
price

                                       56
<PAGE>   69

at the close of trading on July 31, 2000. The following individuals received
grants of options to purchase shares of SCO common stock in the following
amounts:

     - Randy Bresee -- 150,000 shares

     - Doug Michels -- 175,000 shares

     - Mike Orr -- 175,000 shares

     - Steve Sabbath -- 50,000 shares

     - Geoff Seabrook -- 50,000 shares

     Stockholder Agreement.  New Caldera and SCO will enter into a stockholder
agreement at the time of the closing of the combination. This agreement will
give SCO the right to have New Caldera nominate up to two directors for election
to New Caldera's board. These nominees will initially be Mr. Michels and Mr.
            .

     Voting Agreements.  The Canopy Group, Inc. and MTI Technology Corporation
have entered into voting agreements with SCO by which they have agreed to vote
in favor of the combination. Together, these stockholders hold approximately 72%
of the outstanding shares of Caldera. Doug Michels has entered into a voting
agreement with Caldera by which he has agreed to vote in favor of the
combination. Mr. Michels holds approximately 10% of the outstanding shares of
SCO.

                          THE REORGANIZATION AGREEMENT

     This section of this document describes the reorganization agreement. A
copy of the reorganization agreement is attached as Appendix A to this joint
proxy statement/prospectus. The summary is materially complete, but you should
read the full and complete text of the reorganization agreement as it may
contain information that is important to you.

CLOSING

     The closing of the combination will take place as soon as practicable after
the Caldera and SCO meetings and no later than the third business day after all
conditions to closing under the reorganization agreement are satisfied or
waived. The Caldera merger will become effective upon the filing of a
certificate of merger in the offices of the Secretary of State of the State of
Delaware.

WHAT CALDERA SECURITY HOLDERS WILL RECEIVE

     Shares of Common Stock.  Each share of common stock of Caldera that is
issued and outstanding will be automatically converted into one share of New
Caldera common stock. As of September 1, 2000 there were 39,036,847 shares of
Caldera common stock outstanding.

     Stock options.  Each outstanding option to purchase shares of Caldera
common stock will be automatically assumed and converted into an option to
purchase an equivalent number of shares of New Caldera common stock. The
exercise price per share will remain unchanged. As of September 1, 2000 there
were options to purchase 6,968,087 shares of Caldera common stock outstanding.

     Employee stock purchase plan rights.  Each of the outstanding rights to
purchase shares of Caldera common stock under the Caldera Employee Stock
Purchase Plan will be assumed and converted into a right to purchase the same
number of shares of New Caldera common stock on the next purchase date under the
Caldera stock purchase plan following the effective time. The purchase price per
share will be determined in accordance with the stock purchase plan.

                                       57
<PAGE>   70

CALDERA STOCKHOLDERS WILL NOT NEED TO SURRENDER SHARE CERTIFICATES

     Holders of Caldera common stock will not need to surrender their stock
certificates. After the effective time, their stock certificates will be deemed
to represent an equivalent number of shares of New Caldera common stock.

WHAT SCO WILL RECEIVE FOR CONTRIBUTING THE SERVER AND PROFESSIONAL SERVICES
GROUPS TO NEW CALDERA

     - SCO and its employees who join New Caldera will receive approximately
       28.6% of New Caldera on a fully diluted basis, or approximately 18.4
       million shares of New Caldera common stock (including approximately two
       million shares reserved for employee options assumed or replaced by New
       Caldera for options currently held by SCO employees joining New Caldera),
       and SCO will receive $7 million in cash.

     - New Caldera will assume or exchange the outstanding SCO options of the
       employees of SCO who become employees of New Caldera, with the exception
       of David McCrabb, Jack Moyer and Jim Wilt.

     - Each option to purchase shares of SCO common stock assumed or exchanged
       shall be converted into New Caldera options to acquire half the number of
       shares of New Caldera common stock.

     - New Caldera will pay SCO $7 million in cash.

STOCK OPTION AND BENEFIT PLANS AND RELATED SECURITIES

Caldera options

     The term, exercisability, vesting schedule, status as an "incentive stock
option" under section 422 of the Internal Revenue Code, if applicable, and all
other terms and conditions of the Caldera options assumed by New Caldera will be
unchanged.

SCO options

     New Caldera has agreed to assume or exchange the outstanding options of
those SCO employees who will become New Caldera employees, with the exception of
David McCrabb, Jack Moyer and Jim Wilt. Each option to purchase shares of SCO
common stock shall be converted into a New Caldera option to purchase half the
number of shares of New Caldera common stock. Under the assumption, the exercise
price of the New Caldera option will be twice the exercise price per share of
such SCO option. All options which are vested at the effective time will remain
vested and all unvested shares will continue to vest in installments in
accordance with the original vesting schedule. Under the exchange, the exercise
price of the New Caldera option will be the fair market value of New Caldera
common stock immediately prior to the closing of the combination. The vesting
schedule of the New Caldera option will be determined as follows: (i) the number
of vested shares of common stock under the New Caldera option grant will equal
the number of vested shares of common stock subject to the cancelled SCO option
grant immediately prior to the effective time multiplied by 0.25 and (ii) the
remaining unvested replacement options will vest over a period of months
determined by the following equation: 48 months less the product of the number
of months vested under the SCO option grant immediately prior to the effective
time multiplied by 0.5. A vote for the combination will be deemed to constitute
approval of the issuance of New Caldera options in exchange for the assumed SCO
options.

Caldera stock plans

     In addition, the Caldera stock option and stock purchase plans, as proposed
to be amended, will be assumed and continued by New Caldera. See proposals 2 and
3 under "Additional Proposals to be Voted upon by Caldera Stockholders" on page
142. A vote for the combination will be deemed to constitute approval of the
assumption and continuation of the Caldera plans as proposed to be amended.

                                       58
<PAGE>   71

Employee benefit plans

     New Caldera has agreed to use reasonable efforts to provide the Caldera
benefit arrangements and Caldera employee plans to the employees of SCO who
become New Caldera employees. To the extent that New Caldera does not have any
such plan or arrangement in effect in a jurisdiction where there are
transferring employees, New Caldera has agreed to adopt plans providing
comparable benefits to the plans for the transferring employees.

     New Caldera has agreed to provide all transferring employees with the
opportunity to participate in any employee stock option or other incentive
compensation plan of New Caldera on substantially the same terms and conditions
as are available to similarly situated employees of Caldera or New Caldera.
Prior to the effective time, Caldera, New Caldera and SCO will mutually agree
upon an integration plan which will include, among other things, provisions
relating to compensation and other equity incentives for employees.

     New Caldera has agreed to take all steps necessary to cause each of the
benefit arrangements and employee plans of Caldera to waive any waiting period
or other requirement for duration of employment with New Caldera which would
prevent a transferring employee who is otherwise eligible to participate in the
plan from participating in the plan immediately following the effective time.

     New Caldera has also agreed to pro rate any portion of a premium or
deductible with respect to a plan for any transferring employee for any plan
year that commenced prior to the effective time.

     New Caldera has also agreed to take all steps necessary to cause each
employee plan to recognize each transferring employee's length of service under
comparable employee benefit plans maintained by SCO. Therefore, for purposes of
eligibility, participation, vesting and benefit accrual, the transferring
employee will be treated as if employed by New Caldera for such period.

       proposal described below;

     - engage in discussions or negotiations regarding any SCO alternative
       proposal;

     - take any other action intended, designed or reasonably likely to
       facilitate any inquiries or the making of any proposal that constitutes

     "SCO alternative proposal" means any inquiry, proposal or offer relating to
any direct or indirect (a) acquisition, purchase, sale or other disposition of
any of the server or professional services business assets other than in the
ordinary course and disposal of worn or obsolete items consistent with past
practice, (b) acquisition, purchase, sale or other disposition of any of the
voting securities of any contributed company, or (c) merger, consolidation, sale
of any of the assets, liquidation, or similar transaction involving any
contributed company.

     SCO may, in response to an unsolicited SCO alternative proposal,
participate in discussions or negotiations with, furnish information to a third
party, make a recommendation in support of the proposal, or accept the proposal,
subject to the following:

     - the third party has made a bona fide written proposal to the SCO board
       which identifies a price or range of values to be paid for the
       outstanding securities or assets of SCO;

       nationally recognized reputation, that the third party is financially
       capable of consummating the SCO alternative proposal;

       that failure to take such action would be inconsistent with the
       director's fiduciary duties;

       including its principal financial and other material terms and
       conditions, including the identity of the person making the proposal; and

       it reasonably believes would lead to any SCO alternative proposal.

                                       62
<PAGE>   75

     - any claim by any contributing company asserting that the transfer of the
       capital stock of the contributed companies and the contributed stock and

       transfer or a preference under any applicable foreign, state or federal
       law;

       covenants relating to fraudulent conveyances or any liabilities related

       termination by SCO prior to the closing;

     - any breach of representation in the reorganization agreement; or

entire amount of the loss.

     However, in no event shall the amount of indemnification exceed 10% of the
value of 28% of New Caldera common stock on a fully diluted basis, based on the
average closing price of Caldera common stock for the five days prior to the

       (b) with respect to an excess loss account in the stock of any
       contributed company or from a deferred intercompany transaction other
       than among the contributed companies entered into prior to the closing
       and is triggered as a result of any contributed company ceasing to be
       affiliated with SCO;

                                       63
<PAGE>   76

       cannot terminate it;

     - by Caldera, if (a) the board of directors of SCO withdraws or modifies in

       board and New Caldera board;

     - actions brought by a stockholder of New Caldera; or

     These voting provisions do not apply to any proposals for any
recapitalization or combination accomplished in connection with any merger,

                                       66
<PAGE>   79

a type contemplated by Section 351 of the Internal Revenue Code or any other
similar transaction where (a) New Caldera is acquired by a third party, (b)
there has been a "change of control" so that the stockholders of New Caldera
prior to a transaction own, in the aggregate, less than a majority of the
outstanding stock of New Caldera or the acquiring entity after the transaction,
(c) New Caldera acquires another entity, or (d) New Caldera acquires all or
substantially all of the assets of another entity.

Standstill provisions

     Until the fifth anniversary of the combination, SCO will not, without New
Caldera's prior written consent:

     - acquire, or enter into discussions, negotiations, arrangements or
       understandings with any third party to acquire beneficial ownership of
       any New Caldera voting securities if SCO would then beneficially own
       and/or have the right to acquire more than the percentage of New Caldera
       common stock held by it immediately after the closing of the combination,
       which we refer to as the standstill percentage;

     - make, or in any way participate in, any solicitation of proxies with
       respect to the voting of any voting securities of New Caldera; or

     - seek, either alone or in concert with others, to control the New Caldera
       board or the policies of New Caldera.

     The limitations described above shall be suspended upon the earlier to
occur of:

     - the date that a third party not affiliated with SCO commences a tender or
       exchange offer, that is not withdrawn or terminated, and that would
       result in a person or group beneficially owning in the aggregate more
       than 50.0% of the total voting power of New Caldera. If any tender or
       exchange offer is withdrawn or terminated, the standstill limitation will
       be reinstated;

     - the public announcement by New Caldera that it has entered into any
       agreement with respect to a merger, consolidation, combination or similar
       transaction involving New Caldera in which all the stockholders of New
       Caldera collectively will own less than 50.0% of the outstanding voting
       stock of the surviving or acquiring entity immediately after the
       transaction. The standstill limitation will be reinstated if the
       transaction is terminated prior to being completed; or

     - the sale or disposition of substantially all of New Caldera's assets.

     If SCO acquires shares that cause it to own a percentage of New Caldera's
outstanding stock that is greater than the standstill percentage, it will not be
obliged to dispose of any New Caldera voting stock to the extent the increased
shares were acquired:

     - as a result of a recapitalization of New Caldera or a repurchase or
       exchange of securities by New Caldera or any other action taken by New
       Caldera or its affiliates;

     - as the result of any acquisition of New Caldera voting stock made during
       the period when the "standstill" obligations are suspended as described
       above;

     - by way of stock dividend or other distribution or rights or offerings
       made available to holders of shares of New Caldera voting stock
       generally; or

     - with the consent of a majority of the members of New Caldera's board of
       directors that have not been designated by SCO.

Caldera will be the exclusive provider of research and development services to
SCO for its Open Server Unix products. SCO will pay to New Caldera a fee equal
to 110% of New Caldera's direct and indirect costs relating to providing these
services, and SCO will have the right to approve in advance the resources and
deliverables relating to the services to be provided to SCO. The Open Server
research and development agreement will automatically terminate upon the
termination of the sales representative and support agreement.

EMPLOYMENT AGREEMENTS

     The employees of SCO who will become executive officers or are otherwise
considered key employees of New Caldera will enter into employment agreements
with New Caldera. These agreements will provide for employment of one or two
years and severance benefits, among other things. To identify those persons who
are expected to become executive officers of New Caldera and enter into
executive employment agreements, please refer to "Management of Caldera and New
Caldera" on page 113.

PROMISSORY NOTE

     SCO is currently negotiating with Caldera and The Canopy Group, Inc., a
significant stockholder of Caldera, the terms of two separate loan documents
whereby Caldera and Canopy would loan to SCO $7 million and $18 million,
respectively. The principal and any accrued but unpaid interest of each loan
would be due upon the closing of combination or, if the closing were not to
occur, the termination of the reorganization agreement. Caldera and Canopy would
also have the right to convert the principal and interest into shares of SCO.
The principal and interest of each loan will be secured by certain assets of
SCO.

                     THE EMPLOYEE STOCK OPTION ALTERNATIVES

GENERAL

     At the effective time of the combination, each outstanding option to
purchase shares of SCO common stock under SCO's plan, may be either assumed or
replaced on a grant by grant basis by New Caldera at the discretion of each
employee, subject to the terms and conditions set forth in this section.

     A condition to New Caldera assuming or replacing an outstanding option is
that the optionee become employed with New Caldera or its subsidiaries. However,
any such employment relationship will be governed by the terms of an employment
"offer letter" and will only be on an "at will" basis, to the extent permissible
under applicable laws.

ASSUMPTION ALTERNATIVE

     Under the assumption alternative, each SCO stock option will continue to
have its original terms (including the vesting schedule and termination
provisions), and be subject to the conditions that were applicable to the option
immediately prior to the effective time, except that:

     - each SCO stock option will become exercisable for shares of New Caldera
       common stock,

     - the number of shares of New Caldera common stock issuable upon the
       exercise of any given SCO option will be determined by multiplying the
       number of shares of SCO common stock underlying the option immediately
       prior the effective time by 0.5 and rounding down to the nearest whole
       number,

     - the per share exercise price of any given option will be determined by
       dividing the exercise price of the option immediately prior to the
       effective time by 0.5 and rounding up to the nearest whole cent, and

     - the option for shares of New Caldera may not qualify as an incentive
       stock option even though the SCO option may have qualified.

     To illustrate the effect of choosing the assumption alternative for a
specific option grant, assume our combination closes on November 1, 2000 and, at
that point, an employee had an SCO option to purchase 100 shares which was
granted on November 1, 1998 when SCO's common stock was at $8.00. The employee
would receive the following:

     - options to purchase 50 shares of New Caldera common stock,

     - all options which are vested at the effective time will remain vested and
       all unvested shares will continue to vest in installments in accordance
       with the original vesting schedule, and

     - the exercise price of the option would be $16.00.

REPLACEMENT ALTERNATIVE

     Under the replacement alternative, each SCO stock option will be treated as
follows:

     - each SCO stock option will be cancelled and replaced with a new option
       exercisable for shares of New Caldera common stock,

     - the number of shares of New Caldera common stock issuable upon the
       exercise of the replacement option will be determined by multiplying the
       number of shares of SCO common stock underlying the cancelled SCO option
       immediately prior to the effective time by 0.5 and rounding down to the
       nearest whole number,

     - the per share exercise price of any given option will be the fair market
       value of New Caldera common stock immediately after the effective time,
       and

                                       69
<PAGE>   82

     - the vesting schedule of the New Caldera options will be determined as
       follows: (i) the number of vested shares of common stock under the New
       Caldera option grant will equal the number of vested shares of common
       stock subject to the cancelled SCO option grant immediately prior to the
       effective time multiplied by 0.25 and (ii) the remaining unvested
       replacement options will vest over a period of months determined by the
       following equation: 48 months less the product of the number of months
       vested under the SCO option grant immediately prior to the effective time
       multiplied by 0.5.

     To illustrate the effect of choosing the replacement option for a specific
option grant, assume again our combination closes on November 1, 2000 and at
that point an employee had an SCO option to purchase 100 shares which was
granted on November 1, 1998 and which was vested as to 50 shares on November 1,
2000 with an exercise price of $8.00 per share, the employee would receive the
following:

     - options to purchase 50 shares of New Caldera common stock,

     - of the shares vested under the SCO option grant, one-fourth of those, or
       12.5 shares, of New Caldera will remain vested, while the remaining 37.5
       shares will vest over the next thirty-six months (48 months - (24
       months/2)), and

     - the exercise price would be the fair market value of New Caldera common
       stock on November 1, 2000.

PROCEDURE FOR ELECTING OPTION ALTERNATIVE

     If you tender to New Caldera your SCO options and New Caldera accepts them,
assuming the other conditions of the employee stock option assumption and
replacement offer described in this section are met, you will have entered into
a binding agreement with New Caldera upon the terms and subject to the
conditions set forth in this section and in the accompanying notice of election
in Appendix M. You must send a properly completed and duly executed notice of
election to SCO at the address under "-- SCO is Acting as Exchange Agent" on
page 72 on or prior to the expiration date to participate in this assumption and
exchange offer.

     THE METHOD OF DELIVERY OF NOTICES OF ELECTION AND ALL OTHER REQUIRED
DOCUMENTS IS AT THE ELECTION AND RISK OF THE HOLDERS. IF THE DELIVERY IS BY
MAIL, IT IS RECOMMENDED THAT REGISTERED MAIL, PROPERLY INSURED, WITH RETURN
RECEIPT REQUESTED, BE USED IN ALL CASES. SUFFICIENT TIME SHOULD BE ALLOWED TO
ASSURE TIMELY DELIVERY.

     New Caldera expressly reserves the right, at any time or from time to time,
to extend the period of time during which this assumption and replacement offer
is open either to all offerees as a group, and delay acceptance of any election,
by mailing written notice of the extension to the relevant holders as described
below. During any extension, all SCO options previously tendered will remain
subject to the assumption and replacement offer.

NO NOTICES OF ELECTION SHOULD BE SENT TO CALDERA

     All questions as to the validity, form, eligibility, including time of
receipt and acceptance of the notice of election will be determined by New
Caldera and SCO in their sole discretion. This determination will be final and
binding. New Caldera reserves the absolute right to reject any notice of
election not properly delivered. New Caldera also reserves the absolute right in
its sole discretion to waive any defects or irregularities or conditions of the
employee stock option assumption and replacement offer either before or after
the expiration date, including the right to waive the ineligibility of any
holder who seeks to tender SCO option agreements in this assumption or
replacement offer. The interpretation of the terms and conditions of the
assumption and replacement offer as to any particular SCO option either before
or after the expiration date, including the notice of election and the related
instructions, by New Caldera shall be final and binding on all parties. Unless
waived, any defects or irregularities in connection with tenders of

                                       70
<PAGE>   83

SCO options for assumption or replacement must be cured within a reasonable
period of time that New Caldera shall determine. Neither New Caldera, SCO nor
any other person shall be under any duty to give notification of any defect or
irregularity with respect to any tender of SCO option for assumption or
replacement, or shall any of them incur any liability for failure to give any
notification.

CONSEQUENCES OF FAILURE TO ELECT AN ALTERNATIVE

     If you are a server and professional services groups employee and you
accept an offer of employment made by New Caldera, you will automatically become
an employee of New Caldera on the closing date of the combination and are
entitled to participate in the employee stock option assumption and replacement
offer subject to the terms and conditions set forth in this section and the
notice of election. If you are a server and professional services groups
employee and your notice of election is not post-marked by the expiration date
of the assumption and replacement offer period or if you do not submit a notice
of election, your SCO options will terminate according to the terms of the SCO
stock plan. This means that:

     - the unvested portion of your SCO options will terminate as of the closing
       date of the combination;

     - you will have 30 days from the completion of the combination to exercise
       the vested portion of your SCO options; and

     - any vested options that you do not exercise will be cancelled on the 31st
       day after the closing of the combination.

     These consequences will occur because you will no longer be an employee of
SCO and will not be eligible to participate in its plans.

RESALES OF OPTION SHARES

     The assumed or replacement options as well as the shares of New Caldera
common stock issuable upon exercise of the assumed or replacement options will
continue to be subject to restrictions on transfers. In general, the options are
not transferable and the shares of New Caldera common stock issuable upon their
exercise may not be offered or sold unless registered under the Securities Act.
New Caldera anticipates that it will register under the Securities Act the New
Caldera common stock issuable under each assumed or replacement option shortly
after the employee stock option assumption and replacement offer is completed.

NO GUARANTEE OF EMPLOYMENT

     A condition to your receiving a New Caldera option in this assumption and
replacement offer is that you become employed by New Caldera or its
subsidiaries. The tender of a SCO option is not a guarantee that you will be
employed or will continue to be employed by New Caldera or any of its
subsidiaries. Any employment relationship that is created in the future will be
governed by the terms of an employment "offer letter" and will only be on an "at
will" basis.

ACCEPTANCE OF OPTIONS FOR EXCHANGE AND DELIVERY OF NEW CALDERA OPTIONS

     New Caldera will accept, promptly after the expiration date, all SCO
options properly tendered under the notice of election and will exchange with
SCO options for New Caldera options promptly after:

     - you deliver a properly completed and duly executed notice of election;

     - the closing of the combination; and

     - the commencement of your employment with New Caldera or one of its
       subsidiaries.

                                       71
<PAGE>   84

CANCELLATION OF SCO OPTIONS

     Upon the acceptance by New Caldera of your election to have your SCO
options cancelled and replaced, the SCO options subject to that election will be
cancelled and may no longer by exercised.

SCO IS ACTING AS EXCHANGE AGENT

     SCO is acting as the agent for the assumption and replacement offer. All
executed notices of election should be sent via mail, post-marked prior to the
expiration date to SCO at the address set forth below or sent via facsimile to
the number set forth below. We recommend that you use registered mail, return
receipt requested. Questions and requests for assistance, requests for
additional copies of this document or of the notice of election should be
directed to SCO, addressed as follows:

                       SELECTED FINANCIAL DATA OF CALDERA
                    (IN THOUSANDS, EXCEPT PER SHARE AMOUNTS)

     The following tables present portions of Caldera's financial statements.
You should read the selected financial data set forth below in conjunction with
Caldera's financial statements and the related notes included elsewhere in this
joint proxy statement/prospectus and in conjunction with "Caldera Management's
Discussion and Analysis of Financial Condition and Results of Operations"
appearing elsewhere in this joint proxy statement/prospectus. The selected
statement of operations data for the years ended October 31, 1997, 1998 and 1999
and the selected balance sheet data as of October 31, 1998 and 1999 are derived
from, and are qualified by reference to, the audited financial statements and
related notes appearing elsewhere in this joint proxy statement/prospectus. The
selected statement of operations data for the years ended October 31, 1995 and
1996 and the selected balance sheet data as of October 31, 1995, 1996 and 1997
are derived from unaudited financial statements not appearing in this joint
proxy statement/prospectus. The statement of operations data for the nine months
ended July 31, 1999 and 2000 and the balance sheet data as of July 31, 2000 are
derived from unaudited financial statements included elsewhere in this joint
proxy statement/prospectus. In the opinion of management, the selected financial
data for the nine months ended July 31, 1999 and 2000 and as of July 31, 2000
have been prepared on the same basis as the selected financial data derived from
the audited financial statements and include all adjusting entries, consisting
only of normal recurring adjustments, necessary for a fair presentation of
Caldera's financial position and results of operations for those periods.

     Caldera began operations in 1994 as Caldera, Inc., a Utah corporation (the
"Predecessor"). In July 1996, the Predecessor acquired an additional business
line which was not engaged in developing and marketing Linux software. The
Predecessor subsequently made the strategic determination to separate its two
business lines into separate entities and, under an asset purchase agreement,
dated as of September 1, 1998, as amended, sold the assets relating to its
business of developing and marketing Linux software to Caldera Systems, Inc., a
newly formed corporation. Caldera Systems, Inc. has operated as a separate legal
entity engaged in developing and marketing Linux software since September 1,
1998. For purposes of presenting Caldera's financial statements, Caldera has
segregated or "carved-out" the operations relating to the Linux business from
the historical financial statements of the Predecessor. Accordingly, Caldera's
consolidated financial statements in this joint proxy statement/prospectus and
the selected financial data present Caldera's financial condition and results of
operations as if Caldera had existed as a separate legal entity for all periods
presented. The carved-out historical results presented are not necessarily
indicative of what would have actually occurred had Caldera existed as a
separate legal entity and any historical results are not necessarily indicative
of results that may be expected for any future period.

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

     The following discussion should be read in conjunction with Caldera's
Consolidated Financial Statements and Notes thereto, included elsewhere in this
joint proxy statement/prospectus. This discussion contains forward-looking
statements that involve risks and uncertainties. Caldera's actual results could
differ materially from those anticipated in these forward-looking statements as
a result of various factors, including those set forth under "Risk Factors" and
elsewhere in this prospectus.

OVERVIEW

     Caldera began operations in 1994 as Caldera, Inc., a Utah Corporation (the
"Predecessor"). In July 1996, through an asset purchase, the Predecessor
acquired an additional business unit, which was not engaged in developing and
marketing Linux software. The Predecessor subsequently made the strategic
determination to separate its two business lines into separate entities and,
under an asset purchase agreement dated as of September 1, 1998, as amended,
sold the assets relating to its business of developing and marketing Linux
software to Caldera Systems, Inc., a newly formed corporation. Caldera Systems,
Inc. has operated as a separate legal entity engaged in developing and marketing
Linux software since September 1, 1998. For purposes of presenting their
financial statements Caldera has segregated or carved-out the operations related
to the Linux business from the historical financial statements of the
Predecessor. Accordingly, Caldera's consolidated financial statements in this
joint proxy statement/ prospectus and the following discussion present Caldera's
financial condition and results of operations as if Caldera had existed as a
separate legal entity for all periods presented.

     Since September 1, 1998, Caldera has invested heavily in the expansion of
its sales, marketing and professional services organizations to support its
long-term growth strategy. As a result, employee headcount has increased from 28
at September 1, 1998 to 209 at July 31, 2000. Caldera has incurred net losses in
each fiscal period since inception and as of July 31, 2000, had an accumulated
deficit of $53.2 million.

     Substantially all of Caldera's revenue since fiscal 1996 has been derived
from sales of Linux products and related services. Management expects that until
the closing of the combination, the majority of Caldera's revenue will continue
to be derived from sales of eDesktop and eServer products. Subsequent to the
closing of the combination, the majority of Caldera's revenues will be derived
from sales of combined products resulting from the integration of Caldera's
Linux products with the Unix based server products and related applications that
Caldera would acquire in conjunction with the acquisition of the server and
professional services businesses. Related product sales are comprised of
shipments of incomplete box units or documentation materials that customers
request from time to time. Historically, Caldera has experienced substantial
fluctuations in revenue from period to period relating to the introduction of
new products and new versions of existing products. Upon announcement of an
expected release date for new products or upgrades, Caldera often experiences a
significant decrease in sales of existing products. Additionally, Caldera often
experiences the strongest sales for a new product during the first 30 days after
its introduction as Caldera fills advance orders from its distribution channels.

     Caldera began shipping its OpenLinux product in fiscal 1996 through
indirect distribution channels such as distributors, value added resellers,
original equipment manufacturers and system integrators, as well as directly to
the end user using its internal sales and marketing force. Over time, Caldera's
business model has evolved such that Caldera now sells primarily through its
two-tier distribution channels. Caldera began offering Linux training, support
and consulting services during fiscal 1999.

     Caldera markets its software and related products primarily in North
America, Europe, Asia and Australia. Revenue from customers outside the United
States was $0 in fiscal 1997, $56,000 in fiscal 1998, $203,000 in fiscal 1999
and $944,000 in the nine months ended July 31, 2000.

     Caldera recognizes revenue in accordance with the American Institute of
Certified Public Accountants, or AICPA, Statement of Position 97-2, or SOP 97-2.

                                       75
<PAGE>   88

     Revenue from the sale of software is recognized upon delivery of the
product when persuasive evidence of an arrangement exists, the price is fixed or
determinable and collection is probable. All sales into the distribution channel
or to OEMs and VARs require a binding purchase order. Sales to resellers for
which payment is considered to be substantially contingent on the reseller's
success in distributing individual units of the product or sales to resellers
with which Caldera does not have historical experience are accounted for as
consignments and the revenue is recognized once sell-through verification has
been received and payments from customers become due. Prior to October 31, 1999,
Caldera did not have any consignment arrangements. During the nine months ended
July 31, 2000, approximately 15 percent of product revenue was derived on a
sell-through basis. Direct sales to end-users are evidenced by concurrent
payment for the product via credit card and are governed by a license agreement.
Generally, the only multiple element arrangement of initial software sales is
certain telephone and e-mail technical support services Caldera provides at no
additional charge. These services do not include product update or upgrade
rights. After the initial support period, customers can elect to enter into
separate support agreements. The cost of providing the initial support services
are not significant; accordingly, Caldera accrues the estimated costs of
providing the services at the time of revenue recognition. Revenue from the
extended support agreements are deferred and recognized over the period of the
contract or as the services are provided.

     If other significant post-delivery vendor obligations exist or if a product
is subject to customer acceptance, revenue is deferred until no significant
obligations remain or acceptance has occurred. To date, Caldera has not shipped
any software and related products subject to acceptance terms or subject to
other post-delivery vendor obligations. Additionally, Caldera has not recognized
revenue on any contracts with customers that may include customer cancellation
or termination clauses that indicate a demonstration period or otherwise
incomplete transaction.

     Caldera also offers its customers consulting, training and other services
separate from the software sale. The services are not integral to the
functionality of the software and are available from other vendors. These
services revenue are recognized as the services are performed.

     Since inception, Caldera has incurred substantial research and development
costs and has invested heavily in the expansion of its sales, marketing and
professional services organizations to support its long-term growth strategy. As
a result of these investments, Caldera has incurred net losses in each fiscal
period since inception and, as of July 31, 2000, had incurred total net losses
of approximately $49.6 million since inception. Management anticipates that
operating expenses will increase substantially for the foreseeable future as
Caldera increases the number of people and programs in sales and marketing,
product development and professional services. Accordingly, management expects
to incur net losses until at least fiscal year 2002.

     In connection with the grant of stock options to employees during fiscal
1999 and the nine months ended July 31, 2000, Caldera recorded deferred
compensation of $3.1 million and $6.8 million, respectively, representing the
difference between the deemed fair market value of the common stock for
accounting purposes and the exercise price of these options as of the date of
grant. Deferred compensation is presented as a reduction of stockholders' equity
and is amortized over the vesting period of the applicable options. Caldera
expensed $409,000 of deferred compensation during fiscal 1999 and $4.0 million
in the nine months ended July 31, 2000. With respect to the options outstanding
as of July 31, 2000, Caldera expects to expense $1.0 million of deferred
compensation for the remainder of fiscal 2000. Caldera expects to expense
deferred compensation of $2.7 million in fiscal year 2001, $1.4 million in
fiscal year 2002, $643,000 in fiscal year 2003, and $73,000 in fiscal year 2004.

     As a result of an option agreement between The Canopy Group and Ralph J.
Yarro III, which was subsequently rescinded, Caldera expensed a one-time
compensation charge of approximately $372,000 during the nine months ended July
31, 2000. The option agreement allowed Mr. Yarro to purchase shares of Caldera
common stock directly from The Canopy Group. No shares were purchased under the
agreement. Mr. Yarro is the president and chief executive officer of The Canopy
Group and the Chairman of Caldera's board of directors.

     In December 1999 and January 2000, Caldera sold 5.0 million shares of
Series B convertible preferred stock at $6.00 per share, resulting in net
proceeds of approximately $29.8 million. Each share of Series B convertible
preferred stock was immediately convertible into one share of common stock. Due
to the beneficial conversion feature associated with the Series B convertible
preferred stock, during the first quarter of fiscal 2000, Caldera recorded a
preferred stock dividend in the amount of $10.0 million thereby increasing the
net loss applicable to common stockholders. On March 13, 2000 Caldera's major
stockholder, The Canopy Group, sold a warrant for $10,000 to purchase 416,667
shares of our common stock held by The Canopy Group at $5.98 per share for a
two-year period to one of the Series B convertible preferred stockholders. Upon
exercise of the warrant, all proceeds will be paid to The Canopy Group. Caldera
recorded this transaction during the second quarter of fiscal 2000 as if Caldera
had sold the warrant to the stockholder with the fair value of the warrant of
$2,252,717 being recorded as a dividend related to convertible preferred stock
and an offsetting contribution to capital.

     In December 1999 and January 2000, Caldera acquired an equity investment in
Lineo, Inc. in exchange for 1,250,000 shares of common stock, acquired an equity
investment in Evergreen Internet, Inc. in exchange for $2.0 million in cash and
200,000 shares of common stock and acquired an equity investment in Troll Tech
AS and certain license rights in exchange for 106,356 shares of common stock.
These three companies provide strategic technology solutions for the Linux
industry. Caldera has entered into agreements with Troll Tech AS and Evergreen
Internet whereby it will be licensing their technology for inclusion in
Caldera's products and service offerings. Caldera will pay future royalties to
Troll Tech and Evergreen Internet based on its sales of products, which
incorporate their technology. Caldera's licensing agreement with Evergreen
Internet also calls for Evergreen Internet to include Caldera's technology in
its products for which it will be paid future royalties by Evergreen Internet
based on sales of products, which incorporate Caldera's technology. Management
believes that these investments have the potential to benefit Caldera through
increased revenue from product sales, royalties and service opportunities.
Management does not expect that these investments will have a material adverse
impact on future liquidity. The investments in Evergreen Internet and Troll Tech
have been accounted for under the cost method of accounting. Management has
determined that Caldera's investment in Lineo should be accounted for as a
transaction between entities under common control with the transfer being
reflected in its financial statements at Lineo's carryover basis. However, at
the date of the transfer, Lineo had a stockholders' deficit, of which
approximately $150,000 would be associated with the 17% interest Caldera
acquired. Accordingly, Caldera recorded the investment at a nominal value of
$1.00 because Caldera does not have any obligation to fund or reimburse Lineo
for its allocated portion of Lineo's stockholders' deficit. Caldera recorded the
estimated fair value of the shares of its common stock issued to Lineo at $10.0
million with the difference between the $10.0 million and the $1.00 investment
being a distribution to The Canopy Group.

     On May 11, 2000, The Canopy Group transferred 1,761,563 shares of Lineo's
common stock held by The Canopy Group to Caldera. This transfer has been
reflected as a capital contribution by The Canopy Group at Lineo's carryover
basis of $1,966,173. As a result of this transaction, Caldera currently holds a
total of 5,000,000 shares of Lineo's common stock (approximately 14% of Lineo's
outstanding voting stock). Caldera has recorded the total value of its
investment at $1,966,174.

     In September 2000, Caldera and Metrowerks Holdings, Inc., an affiliate of
Motorola, Inc., entered into a Stock Purchase and Sale Agreement whereby Caldera
and The Canopy Group are to sell 2.0 million and 1.0 million shares of common
stock of Lineo, Inc. to Metrowerks Holdings at $7.50 per share. The sale will
close upon the receipt of certain required regulatory approvals and the
completion of other closing conditions. The difference between the $7.50 per
share price and Caldera's carrying amount will be reflected as a capital
contribution.

     Software and related products revenue is comprised of revenue from the sale
of software and other products such as shipments of incomplete box units or
documentation materials. Services revenue is comprised of training royalties and
tuition fees, consulting fees and customer support fees.

                                       77
<PAGE>   90

     Cost of software and related products revenue primarily consists of costs
for production, packaging, fulfillment and shipment of product offerings.
Additionally, royalties paid to third parties for inclusion of their software
products in Caldera's product offering are included in these costs.

     Included in sales and marketing expenses are the following: advertising,
channel promotions, marketing development funds, promotional activities, public
relations, trade show and personnel-related expenses such as salaries, benefits,
commissions, recruiting fees, travel and entertainment expenses.

     Research and development expenses consist of payroll and related costs for
software engineers, technical writers, quality assurance and research and
development management personnel and the costs of materials used by these
employees in the development of new or enhanced product offerings. Also included
are the costs associated with outside contractors.

     General and administrative expenses are composed of professional fees,
salaries and related costs for accounting, administrative, finance, human
resources, information systems and legal personnel as well as costs associated
with implementing and expanding our internal information and management
reporting systems.

NINE-MONTH PERIODS ENDED JULY 31, 2000 AND 1999

Revenue

     Revenue was $3.1 million for the nine-month period ended July 31, 2000 and
$2.2 million for the nine-month period ended July 31, 1999. During each of these
nine-month periods, revenue was generated primarily from the sale of software
and related products. Revenue from international customers was approximately 30
percent of total revenue for the nine-month period ended July 31, 2000, and 6
percent of total revenue for the nine-month period ended July 31, 1999.

     Software and Related Products.  Software and related products revenue was
$2.1 million for the nine-month period ended July 31, 2000 and $2.0 million for
the nine-month period ended July 31, 1999, an increase of $151,000, or 8%. The
primary component of software and related product revenue for the nine months
ended July 31, 2000 was derived from sales of eDesktop and eServer products.

     Services.  Services revenue was $953,000 for the nine-month period ended
July 31, 2000 and $179,000 for the nine-month period ended July 31, 1999, an
increase of $774,000, or 433%. The increase in services revenue over the
nine-month period of the prior year was primarily attributed to Caldera's
increased education and training-related offerings, promotional fees received
from Caldera's electronic Linux marketplace program and the increased
effectiveness of marketing efforts for these programs.

Cost of Revenue

     Cost of Software and Related Products Revenue.  Cost of software and
related products revenue was $1.5 million for the nine-month period ended July
31, 2000 and $1.3 million for the nine-month period ended July 31, 1999, an
increase of $234,000, or 19%. Cost of software and related products revenue as a
percentage of software and related products revenue was 69% for the nine-month
period ended July 31, 2000 and 63% for the nine-month period ended July 31,
1999. The increase of 6 percentage points was due to decreases in sales prices
while the costs have remained comparable.

     Cost of Services Revenue.  Cost of services revenue was $1.4 million for
the nine-month period ended July 31, 2000 and $397,000 for the nine-month period
ended July 31, 1999, an increase of $974,000, or 245%. The increase was
primarily due to hiring additional employees and other internal costs to
increase our service and support offering capabilities as well as all costs
incurred from our electronic Linux marketplace program.

Operating Expenses

     Sales and Marketing.  Sales and marketing expenses were $10.5 million for
the nine-month period ended July 31, 2000 and $2.4 million for the nine-month
period ended July 31, 1999, an increase of $8.1 million, or 347%. The increase
in expense was primarily attributed to additional sales and marketing salaries
and benefits as headcount totals increased significantly, advertising,
tradeshows and related expenses, increases in marketing development to build and
expand our distribution channels, and initial costs related to the establishment
of our electronic Linux marketplace.

     Research and Development.  Research and development expenses were $3.4
million for the nine-month period ended July 31, 2000 and $1.6 million for the
nine-month period ended July 31, 1999, an increase of $1.8 million, or 112%. The
increase in research and development expenses was primarily attributed to
payroll and related costs for additional employees for software development and
quality assurance. Other increases were for product localization in various
international locations as well as for strategic development.

     General and Administrative.  General and administrative expenses were $4.5
million for the nine-month period ended July 31, 2000 and $1.2 million for the
nine-month period ended July 31, 1999, an increase of $3.3 million, or 281%. The
increase was primarily attributed to increased salaries and benefits for
additional general and administrative employees and increased facilities and
related costs.

     Amortization of Deferred Compensation.  During the nine-month period ended
July 31, 2000, Caldera amortized $4.0 million of deferred compensation. During
the nine-month period ended July 31, 1999 Caldera amortized $24,000 of deferred
compensation.

Other Income (Expense), net

     Other income (expense), net consists primarily of interest expense on
borrowings and interest income received on cash and cash equivalents. Interest
expense was $1,000 during the nine-month period ended July 31, 2000 and $242,000
during the nine-month period ended July 31, 1999. Other income (expense) was
$2.1 million during the nine-month period ended July 31, 2000 and ($2,000)
during the nine-month period ended July 31, 1999. The increase is primarily
related to interest income on the proceeds received from the issuance of Series
B preferred stock and the initial public offering.

Provision for Income Taxes

     For the nine-month periods ended July 31, 2000 and 1999, Caldera's
subsidiary, Caldera GmbH, incurred income tax expense of $39,000 and $25,000,
respectively.

Dividends Related to Convertible Preferred Stock

     During the nine-month period ended July 31, 2000, Caldera's recorded
preferred stock dividends of $12.3 million. The preferred stock dividends
comprised (i) a warrant that was sold to Egan-Managed Capital by Canopy and (ii)
a beneficial conversion feature related to the issuance of 5.0 million shares of
Series B convertible preferred stock. The estimated fair market value of the
warrant was determined to be $2.3 million using the Black-Scholes option-pricing
model and the value of the beneficial conversion feature was determined to be
$10.0 million.

FISCAL YEARS ENDED OCTOBER 31, 1997, 1998 AND 1999

Revenue

     Revenue was $1.1 million for fiscal 1997, $1.1 million for fiscal 1998 and
$3.1 million for fiscal 1999. During fiscal 1997 and fiscal 1998, all revenue
was derived from our software and related products offerings.

     Software and Related Products.  Software and related products revenue was
$1.1 million in fiscal 1997, $1.1 million in fiscal 1998, and $2.8 million in
fiscal 1999, representing a decrease of $60,000, or 5%, from fiscal 1997 to
fiscal 1998 and a $1.7 million, or 162%, increase from fiscal 1998 to fiscal
1999. The slight decrease in software and related products revenue from fiscal
1997 to fiscal 1998 was due to a reduction of capital for sales and marketing
activities and a diversion of limited resources allocated to Caldera's business
because of growth of non-related product lines associated with Caldera, Inc. The
increase in software and related product revenue from fiscal 1998 to fiscal 1999
was a result of management's expansion of marketing efforts, as well as the
increased market awareness of the Linux operating system.

     Services.  Caldera began to realize service revenue in fiscal 1999. This
revenue was $277,000 or 9% of total revenue in fiscal 1999. Service revenue was
mostly derived from sales of training-related offerings and tuition fees.

Cost of Revenue

     Cost of Software and Related Products Revenue.  Cost of software and
related products revenue was $1.1 million in fiscal 1997, $1.0 million in fiscal
1998 and $2.4 million in fiscal 1999, representing a $125,000, or 11%, decrease
from fiscal 1997 to fiscal 1998 and a $1.4 million, or 135%, increase from
fiscal 1998 to fiscal 1999. On a percentage basis of related revenue, cost of
software and related products revenue was 102% in fiscal 1997, 96% in fiscal
1998 and 86% of fiscal 1999. The decrease in the cost of

                                       80
<PAGE>   93

revenues percentage from fiscal 1997 to fiscal 1998 and from fiscal 1998 to
fiscal 1999 primarily resulted from reduced royalty expenses as a component of
product costs as certain third-party software packages were open sourced and the
elimination of certain other royalty-bearing components. In addition, the
decrease from fiscal 1998 to fiscal 1999 resulted from improved margins on
increased volumes. These improvements in fiscal 1999 were partially offset by an
increase in the reserve for excess and obsolete inventory brought about by the
over-purchase of units of Caldera's product from its manufacturer. The units
were purchased in September 1999 in connection with the release of version 2.3
of our OpenLinux product. As of October 31, 1999, Caldera had reserved for all
but $90,000 of OpenLinux 2.3 finished goods inventory which Caldera expected to
sell and $79,000 of raw materials and components. The negative gross margin
incurred in fiscal 1997 was due to the payment of significant royalties. During
fiscal 1997, Caldera's product incorporated substantial amounts of proprietary
software, which has since been eliminated or open sourced.

     Cost of Services Revenue.  Caldera began to realize services revenue in
fiscal 1999. Cost of services revenue was $538,000, or 194%, of related revenue
during fiscal 1999. The negative margin incurred during fiscal 1999 is due to
Caldera's hiring of employees and building additional infrastructure in
anticipation of future training and support revenues.

     Write-off of Prepaid Royalties.  During fiscal 1996 and 1997, Caldera
entered into royalty agreements with a supplier pursuant to which Caldera
prepaid royalties of approximately $2.1 million. During fiscal 1998, Caldera
asserted that the supplier breached the terms of the royalty agreements and
determined that the remaining prepaid royalties, in the amount of $1.4 million,
were impaired and accordingly Caldera wrote off the remaining balance.
Management determined the asset was impaired because its value was tied to the
intellectual property value of the licenses Caldera had purchased. The vendor
breached the terms of the contract in management's view, when it open sourced
some of the related software. When the vendor decided to open source the
software, the licenses Caldera had purchased had no value in relation to that
software. Additionally, Caldera discontinued the development of a product
related to the licensed software resulting in the complete impairment of the
prepaid asset. Management determined that any attempt to pursue legal action
against the supplier would be costly and uncertain given the resources required
to pursue such an action and the uncertainties relating to interpreting the
royalty agreements.

Operating Expenses

     Sales and Marketing.  Sales and marketing expenses were $4.6 million in
fiscal 1997, $2.2 million in fiscal 1998 and $4.8 million in fiscal 1999,
representing a decrease of $2.4 million, or 52%, from fiscal 1997 to fiscal 1998
and an increase of $2.5 million, or 114%, from fiscal 1998 to fiscal 1999. Sales
and marketing expenses represented 414% of our total revenues in fiscal 1997,
210% of Caldera's total revenues in fiscal 1998 and 156% of Caldera's total
revenues in fiscal 1999. The decrease in amounts expended from fiscal 1997 to
fiscal 1998 was due to the reduction in the resources devoted to the Linux
business, prior to Caldera's reorganization. During fiscal 1999, Caldera
expanded its sales and marketing efforts.

     Research and Development.  Research and development expenses were $2.1
million in fiscal 1997, $1.5 million in fiscal 1998 and $2.3 million in fiscal
1999, representing a decrease of $647,000, or 30%, from fiscal 1997 to fiscal
1998 and an increase of $813,000, or 55%, from fiscal 1998 to fiscal 1999.
Research and development costs represented 191% of our total revenue in fiscal
1997, 141% of total revenue in fiscal 1998 and 76% of total revenue in fiscal
1999. The decrease from fiscal 1997 to fiscal 1998 was primarily related to a
reduction of capital for research and development activities and a diversion of
limited resources allocated to Caldera's business because of growth of
non-related product lines associated with the Predecessor. The increase in
research and development expenses from fiscal 1998 to fiscal 1999 was due to an
increased investment in the number of software developers, quality assurance
personnel and outside contractors to support Caldera's product development and
testing activities including the development of training courses and technical
support offerings.

     General and Administrative.  General and administrative expenses were
$797,000 in fiscal 1997, $1.8 million in fiscal 1998, and $1.7 million in fiscal
1999, representing an increase of $1.0 million, or 126%,

                                       81
<PAGE>   94

from fiscal 1997 to fiscal 1998 and a decrease of $51,000, or 3%, from fiscal
1998 to fiscal 1999. General and administrative costs represented 71% of total
revenue in fiscal 1997, 170% of total revenue in fiscal 1998 and 57% of total
revenue in fiscal 1999. The increase from fiscal 1997 to fiscal 1998 was
primarily the result of the significant fees associated with Caldera's
reorganization in 1998. The increase also reflects the employment of additional
administrative, executive, and finance personnel during most of fiscal 1998.
General and administrative expenses remained fairly constant from fiscal 1998 to
fiscal 1999 as the nonrecurrence of the costs of reorganization was more than
offset by the increase in personnel in 1999.

     Amortization of Deferred Compensation.  In connection with the granting of
stock options to employees during fiscal 1999, Caldera recorded deferred
compensation of $3.1 million. During fiscal 1999, Caldera amortized $409,000 of
deferred compensation. Caldera did not record any deferred compensation or
amortization during fiscal 1997 and 1998 as no stock options were granted in
those years.

Other Income (Expense), net

     Other income (expense), net, which consists principally of interest
expense, was $570,000 in fiscal 1997, $1.1 million in fiscal 1998, and $228,000
in fiscal 1999, representing an increase of $506,000, or 89%, from fiscal 1997
to fiscal 1998 and a decrease of $847,000, or 79%, from fiscal 1998 to fiscal
1999. The increase between fiscal 1997 and fiscal 1998 resulted from additional
borrowings to fund operating losses. During fiscal 1999, these borrowings were
effectively converted to common stock in connection with Caldera's
incorporation. After the incorporation in fiscal 1998, Caldera entered into a
secured convertible promissory note arrangement with its major stockholder.
Caldera borrowed amounts during the last portion of fiscal 1998 and during
fiscal 1999 under this agreement. These borrowings were converted into common
stock through the exercise of the conversion feature in August 1999.

Income Taxes

     For fiscal years 1998 and 1999 Caldera's German subsidiary, Caldera
Deutschland, GmbH, incurred income tax expense of $34,000 and $35,000,
respectively. As of October 31, 1999, Caldera had net operating loss
carryforwards for federal and state income tax reporting purposes of
approximately $10.6 million that expire at various dates from 2018 to 2019. The
Internal Revenue Code contains provisions that likely could reduce or limit the
availability and utilization of Caldera's net operating loss carryforwards. For
example, limitations are imposed on the utilization of net operating loss
carryforwards if certain ownership changes have taken place or will take place.

     Caldera had deferred tax assets, including our net operating loss
carryforwards and other temporary differences between book and tax deductions,
totaling approximately $11.1 million as of October 31, 1999. A valuation
allowance in the amount of $11.1 million has been recorded as of October 31,
1999 as a result of uncertainties regarding the realizability of the deferred
tax asset balance.

QUARTERLY RESULTS OF OPERATIONS

     The following table sets forth certain unaudited quarterly statement of
operations data for the last five quarters. This information has been derived
from Caldera's unaudited consolidated financial statements, which, in
management's opinion, have been prepared on the same basis as the audited
financial statements and include all adjustments, consisting only of normal
recurring adjustments, necessary for a fair presentation of the information for
the quarters presented. This information should be read in conjunction with the
audited financial statements and related notes included elsewhere in this joint
proxy statement/ prospectus. Caldera has experienced, and expects to continue to
experience, fluctuations in operating

</TABLE>

FLUCTUATIONS IN QUARTERLY RESULTS

     Historically, Caldera has experienced substantial fluctuations in revenues
from period to period relating to the introduction of new products and new
versions of existing products. Upon announcement of an expected release date for
new products or upgrades, Caldera often experiences a significant decrease in
sales of existing products. Additionally, Caldera often experiences the
strongest sales for a new product during the first 30 days after its
introduction as it fills advance orders from its distribution partners.

     Software and related products revenue during the quarter ended October 31,
1999 decreased from the prior quarter in spite of the release of version 2.3 of
OpenLinux in September 1999. Sales of version 2.3 were lower than sales of
version 2.2 due to version 2.3 including only minor enhancements from version
2.2. The lower sales of version 2.3 continued into the quarter ended January 31,
2000, which resulted in a decrease in software revenue during the quarter ended
January 31, 2000 from the prior quarter. Caldera released eDesktop 2.4 during
the quarter ended April 30, 2000, and consequently revenue increased from the
prior quarter. Caldera did not have a new release during the quarter ended July
31, 2000 when our revenue decreased.

     Services revenue has increased consistently from quarter to quarter as
Caldera has increased its education and training-related offerings, as well as
support and consulting services. Caldera has also increased personnel to promote
its services offerings.

     Caldera has incurred operating losses since inception and may never achieve
profitability in the future. Management believes that future operating results
will be subject to quarterly fluctuations due to a variety of factors, many of
which are beyond its control. Factors that may affect quarterly results include:

     - the interest level of electronic solution providers in recommending
       Caldera's Linux business solutions to end users;

     - the introduction, development, timing, competitive pricing and market
       acceptance of Caldera's products and services and those of its
       competitors;

     - changes in general economic conditions, such as recessions, that could
       affect capital expenditures and recruiting efforts in the software
       industry in general and in the Linux environment in particular;

     - the magnitude and timing of marketing initiatives;

     - changing business attitudes toward Linux as a viable operating system
       alternative to other competing systems;

     - the maintenance and development of Caldera's strategic relationships with
       technology partners and solution providers;

     - the attraction, retention and training of key personnel; and

     - Caldera's ability to manage our anticipated growth and expansion.

                                       83
<PAGE>   96

     As a result of the factors listed above and elsewhere in the "Risk Factors"
section of this joint proxy statement/prospectus, it is possible that in some
future periods Caldera's results of operations may fall below management's
expectations as well as the expectations of public market analysts and
investors. In addition, Caldera plans to significantly increase operating
expenses to expand sales and marketing, administration, consulting and training,
maintenance and technical support and research and development groups. If
revenue falls below management's expectations in any quarter and Caldera is
unable to reduce spending quickly in response, operating results would be lower
than expected.

LIQUIDITY AND CAPITAL RESOURCES

     Since inception as a separate legal entity in August 1998, Caldera has
funded its operations primarily through loans from its major stockholder and
through sales of common and preferred stock.

     As of July 31, 2000, Caldera had cash and cash equivalents of $28.8 million
and working capital of $85.6 million. Increases in cash and cash equivalents and
working capital from October 31, 1999 were the result of net proceeds received
from the Series B preferred stock offering completed in January 2000 and net
proceeds received from the initial public offering completed in March 2000. Cash
used in operations, investment in short-term securities and $2.0 million cash
investment in Evergreen Internet, Inc. partially offset these increases in cash
and cash equivalents.

     Net cash used in operations during the nine-month period ended July 31,
2000 was $15.3 million. Cash used in operations was primarily attributed to the
net loss of $20.0 million. Caldera also paid $1.25 million to Sun Microsystems,
Inc. for certain rights to license software. These uses of cash were partially
offset by non-cash charges for the amortization of deferred compensation,
depreciation and amortization, and common stock issued for services. Net cash
used in operating activities was $8.8 million in fiscal 1997, $5.1 million in
fiscal 1998 and $7.6 million in fiscal 1999. Cash used in operating activities
was primarily attributed to the net loss of $8.1 million in fiscal 1997, net
loss of $8.0 million in fiscal 1998 and net loss of $9.4 million in fiscal 1999
offset by non-cash expenses and changes in working capital.

     Investing activities have historically consisted of purchases of property
and equipment and certain intangible assets as well as a $15.0 million payment
during fiscal 1999 to the Predecessor, in connection with the reorganization of
the Predecessor and Caldera's own incorporation. During the nine-month period
ended July 31, 2000, cash used in investing activities was $59.3 million, of
which $56.0 million was used to purchase short-term investments to maximize the
yield on available cash balances. Additionally, during the nine months ended
July 31, 2000, Caldera invested $2.0 million in the common stock of Evergreen
Internet, Inc., a strategic partner, and paid $1.3 million for property and
equipment. Capital expenditures totaled $306,000 in fiscal 1997, $170,000 in
fiscal 1998, and $587,000 in fiscal 1999. Additionally, Caldera invested $80,000
in certain intangible technology during fiscal 1999. Historically, the
acquisition of property and equipment has been primarily through cash purchases.
Management anticipates that Caldera will experience an increase in the level of
capital expenditures, lease commitments and investment activities as Caldera
grows its operations.

     Financing activities provided $103.2 million during the nine-month period
ended July 31, 2000. The primary sources of cash during the nine-month period
ended July 31, 2000 included net proceeds of $29.8 million received in
connection with the Series B preferred stock financing completed in January 2000
and net proceeds of $71.8 million received in connection with the initial public
offering in March 2000. Caldera also received $1.5 million from a stock
subscription receivable. Subsequent to July 31, 2000 Caldera received $1.5
million on a stock subscription receivable from MTI Technology Corporation.

     Financing activities provided $9.3 million in fiscal 1997, $4.9 million in
fiscal 1998 and $23.3 million in fiscal 1999. In fiscal 1997, cash provided by
financing activities consisted of $9.3 million received in borrowings from The
Canopy Group, Inc. that accrued interest at rates ranging from 8.25 percent to
8.50 percent based on the prime rate. Caldera accrued $609,000 in interest
associated with these borrowings. In fiscal 1998, cash provided by financing
activities consisted primarily of $4.4 million additional borrowings from The
Canopy Group that accrued interest at rates ranging from 8.00 percent to

                                       84
<PAGE>   97

8.50 percent based on the prime rate. Caldera accrued $882,000 in interest
associated with these borrowings. Caldera also received $519,000 in equity
funding from The Canopy Group upon its incorporation. During fiscal 1999, cash
provided by financing activities consisted primarily of $15.5 million of equity
funding received from The Canopy Group and $3.0 million of equity funding from
MTI Technology Corporation. Additionally, Caldera received $4.8 million from The
Canopy Group under a secured convertible promissory note agreement that accrued
interest at the prime rate less one-half percent which was calculated at 7.25
percent. Caldera accrued $88,000 in interest associated with these borrowings.
These proceeds plus accrued interest were converted to equity during fiscal
1999.

     As of July 31, 2000, Caldera had no outstanding debt obligations. As of
October 31, 1999, Caldera had only one debt arrangement for approximately
$9,500. As of that date, Caldera had no other bank or other borrowing
arrangements in place.

     Management believes that its current cash and cash equivalents and
short-term investments will be sufficient to meet capital expenditures and
working capital requirements for at least the next twelve months. However,
Caldera may need to raise additional funds to support more rapid expansion,
respond to competitive pressures, acquire complimentary businesses or
technologies or respond to unanticipated requirements. Management cannot assure
you that additional funding will be available in amounts or on terms acceptable
to Caldera. If sufficient funds are not available or are not available on
acceptable terms, the ability to fund expansion, take advantage of acquisition
opportunities, develop or enhance our services or products, or otherwise respond
to competitive pressures would be significantly limited.

RECENT ACCOUNTING PRONOUNCEMENTS

     In June 1998, the Financial Accounting Standards Board, or FASB, issued
Statement of Financial Accounting Standards No. 133, "Accounting for Derivative
Instruments and Hedging Activities", or SFAS 133. SFAS 133 establishes new
accounting and reporting standards for companies to report information about
derivative instruments, including certain derivative instruments embedded in
other contracts (collectively referred to as derivatives), and for hedging
activities. This statement was effective for financial statements issued for all
fiscal quarters of fiscal years beginning after June 15, 1999. In June 1999,
FASB delayed the effective date of SFAS 133 for one year, to apply to fiscal
quarters of all years beginning after June 15, 2000. Management does not expect
this statement to have a material impact on our results of operations, financial
position or liquidity.

     In December 1999, the Securities and Exchange Commission ("SEC") staff
issued Staff Accounting Bulletin No. 101 ("SAB 101"), "Revenue Recognition in
Financial Statements". This pronouncement summarizes certain of the SEC Staff's
views in applying generally accepted accounting principles to selected revenue
recognition issues. The Company is required to adopt SAB 101 during the first
quarter of fiscal year 2001. Although management is currently evaluating the
impact, if any, of SAB 101, management does not presently believe it will have a
material impact on the Company's results of operations, financial position or
liquidity.

     In March 2000, the FASB issued Interpretation No. 44 "Accounting for
Certain Transactions involving Stock Compensation, an interpretation of
Accounting Principles Board Opinion No. 25 ("APB 25")". This interpretation
clarifies the definition of employee for purposes of applying APB 25, the
criteria for determining whether a plan qualifies as a noncompensatory plan, the
accounting consequence of various modifications to the terms of a previously
fixed stock option or award, and the accounting for an exchange of stock
compensation awards in a business combination. This interpretation is effective
July 1, 2000, but certain conclusions in this interpretation cover specific
events that occur after either December 15, 1998, or January 12, 2000. To the
extent that this interpretation covers events occurring during the period after
December 15, 1998 or January 12, 2000, but before the effective date of July 1,
2000, the effects of applying this interpretation are recognized on a
prospective basis from July 1, 2000.

QUALITATIVE AND QUANTITATIVE DISCLOSURES ABOUT MARKET RISK

     Caldera's products and services are primarily developed in the United
States and marketed in North America, and to a lesser extent in Europe and
Asia/Pacific regions. As a result, financial results could be affected by
changes in foreign currency exchange rates or weak economic conditions in
foreign markets. Because all of the Caldera's revenues are currently denominated
in U.S. dollars, a strengthening of the dollar could make its Linux products
less competitive in foreign markets.

     Caldera's German subsidiary, Caldera Deutschland, GmbH, performs research
and development activities for us. This subsidiary is currently Caldera's only
foreign operation. To date, foreign currency fluctuations have had little effect
on Caldera's business because only its German subsidiary's contracts, payables
and receivables are denominated in a foreign currency. As of July 31, 2000, the
assets of Caldera Deutschland were approximately $840,000. All other
transactions of Caldera's business are denominated in the U.S. dollar. As time
passes and as management sees fit, more transactions in Europe and Asia may be
denominated in local currencies. As Caldera expands operations in Europe and
Asia, management will continue to evaluate its foreign currency exposures and
risks and develop appropriate hedging or other strategies to manage those risks.
Management has not revised its current business practices to conform to Europe's
conversion to the euro. Caldera has not modified any of its products to address
Europe's conversion to the euro. Additionally, Caldera has not engaged in any
foreign currency hedging activities.

     The primary objective of Caldera's cash management strategy is to invest
available funds in a manner that assures maximum safety and liquidity and
maximizes yield within such constraints. A portion of the securities that
Caldera invests in may be subject to market risk, which means that a change in
prevailing rates or market conditions may adversely affect the principal amount
of the investment. To minimize this risk, Caldera will invest in a broad range
of short-term fixed income securities with varying maturities. As of July 31,
2000, short-term investments included money market instruments, tax-exempt
municipal funds, notes, and bonds, and US government security backed
instruments. The Company does not borrow money for short-term investment
purposes.

YEAR 2000 COMPLIANCE

     Prior to January 1, 2000, there was a great deal of concern regarding the
ability of computers to adequately recognize 21st century dates from 20th
century dates due to the two-digit date fields used by many systems. Most
reports to date, however, are that computer systems are functioning normally and
the compliance and remediation work accomplished leading up to 2000 was
effective to prevent any problems. Computer experts have warned that there may
still be residual consequences of the change in centuries and any such
difficulties could result in a decrease in sales of our products, an increase in
allocation of resources to address Year 2000 problems of our customers without
additional revenue commensurate with such dedication of resources, or an
increase in litigation costs relating to losses suffered by our customers due to
such Year 2000 problems.

     SELECTED FINANCIAL DATA OF THE SERVER AND PROFESSIONAL SERVICES GROUPS
                                 (IN THOUSANDS)

     The following selected historical financial data for the server and
professional services groups for the years ended September 30, 1998 and 1999 and
the nine months ended June 30, 2000 and the balance sheet data as of September
30, 1999 and June 30, 2000 are derived from, and qualified by reference to, the
audited financial statements and related notes appearing elsewhere in this proxy
statement/prospectus.

     The selected statement of operations data for the nine months ended June
30, 1999 are derived from unaudited financial statements included elsewhere in
this proxy statement/prospectus. In the opinion of management, the selected
financial data for the nine months ended June 30, 1999 have been prepared on the
same basis as the audited financial statements and include all adjusting
entries, consisting only of normal recurring adjustments, necessary for a fair
presentation of the server and professional services groups financial position
and results of operations for such period.

     For purposes of presenting the financial statements of the server and
professional services groups, the related operations have been segregated or
"carved-out" from the historical financial statements of SCO. Accordingly, the
financial statements of the server and professional services groups included in
this joint proxy statement/prospectus and the selected financial data present
the financial condition and results of operations as if the server and
professional services groups had existed as a separate legal entity for all
periods presented. The carved-out historical results presented are not
necessarily indicative of what would have actually occurred had the server and
professional services groups existed as a separate legal entity and any
historical results are not necessarily indicative of results that may be
expected for any future period.

               DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
                             RESULTS OF OPERATIONS

     This Management's Discussion and Analysis of Financial Condition and
Results of Operations as of June 30, 2000 and for the nine months ended June 30,
2000 and 1999 should be read in conjunction with the sections of the server and
professional services groups' financial statements and related notes included
elsewhere in this proxy statement/prospectus. In addition, the portion of this
Management's Discussion and Analysis of Financial Condition and Results of
Operations as of September 30, 1999 and for the years ended September 30, 1999
and 1998 should be read in conjunction with the sections of the server and
professional services groups' audited financial statements and related notes
included elsewhere in this proxy statement/prospectus.

OVERVIEW

     On August 1, 2000, SCO announced that it had reached an agreement with
Caldera under which Caldera would purchase for stock and cash SCO's server and
professional services groups. Under the terms of the agreement SCO would retain
the rights to its OpenServer product with Caldera continuing to act as a sales
agent on SCO's behalf for this product.

     The server and professional services groups operate as a global leader in
server software for networked business computing, and the world's leading
provider of UNIX(R) server operating systems. The server and professional
services groups sell and support their products through a worldwide network of
more than 15,000 distributors, resellers, system integrators and OEMs.

     The mission of the server and professional services groups is to create,
market and support the server software that system builders choose for networked
business computing. SCO believe that server-based network computing, which is
based on Internet and web technologies, enables businesses to dramatically
improve their customer information flow and business transaction efficiencies.
Companies that adopt a server-based network computing model can understand their
customers better, reach wider potential markets, bring products to market faster
and improve their overall customer satisfaction levels. With server-based
computing and products and services of the server and professional services
groups, IT professionals can immediately leverage their existing investments,
deploy applications faster and dramatically cut the cost of systems
administration and management.

     In addition to historical information contained herein, this Discussion and
Analysis contains forward-looking statements. These statements involve risks and
uncertainties and can be identified by the use of forward-looking terminology
such as "estimates," "projects," "anticipates," "plans," "future," "may,"
"will," "should," "predicts," "potential," "continue," "expects," "intends,"
"believes," and similar expressions. Examples of forward looking statements
include those relating to financial risk management activities and the adequacy
of financial resources for operations. These and other forward-looking
statements are only estimates and predictions. While SCO believes that the
expectations reflected in the forward-looking statements are reasonable, actual
results of the server and professional services groups could differ materially.
Readers are cautioned not to place undue reliance on these forward-looking
statements, which reflect management's expectations only as of the date hereof.
SCO undertakes no obligation to publicly release the results of any revision to
these forward-looking statements, which may be made to reflect events or
circumstances after the date hereof or to reflect the occurrence of
unanticipated events.

RESULTS OF OPERATIONS

Net Revenues

     The net revenues of the server and professional services groups are derived
from software licenses and fees for services, which include engineering
services, consulting, support and training. Product license revenues are
recognized upon shipment, provided a signed contract exists, the fee is fixed
and

                                       89
<PAGE>   102

determinable, collection is probable and returns can be reasonably estimated. An
estimate for product returns is made upon recognition of revenue from customers
having return rights. For sales through distributors we do not have the data to
reasonably estimate returns and therefore recognize revenue when this right
elapses, which occurs upon a sale by the distributor.

     Net revenues for the nine months ended June 30, 2000 increased to $56.2
million from $54.7 million in the same period in fiscal 1999. Net revenues for
fiscal 1999 were $76.9 million, an increase of 34% from $57.2 million in fiscal
1998. The stronger revenue performance in fiscal 1999 was across all geographies
and is attributable to several factors including the ease of electronic
licensing, increased customer contacts as a result of added sales resources and
Y2K upgrade sales. For the nine months ended June 30, 2000 and 1999 and for the
fiscal years ended September 30, 1999 and 1998, no single customer accounted for
greater than 10% of the net revenues of the server and professional services
groups.

License Revenues.

     License revenues for the nine months ended June 30, 2000 were $45.3 million
compared to $43.8 million for the same period of fiscal 1999. License revenues
for fiscal 1999 were $62.1 million, an increase of 45% compared to $42.8 million
in fiscal 1998. The year over year increase is due to strong revenue performance
in all geographies, growing electronic licensing sales, Y2K upgrade sales, and
increased customer contacts due to higher sales resources.

Service Revenues.

     Services revenues were $10.9 million for both the nine month periods ended
June 30, 2000 and 1999. Service revenues represented 19% of total revenue for
both the fiscal 2000 and fiscal 1999 periods. Service revenue for fiscal year
1999 was $14.8 million, or 18% of total revenue, compared to $14.4 million, or
25% of total revenue, for fiscal year 1998.

COST OF REVENUES

     The server and professional services groups' overall cost of revenues as a
percentage of net revenues can be affected by mix changes in net revenue
contribution between product families, geographic regions and channels of
distribution, since both price and cost characteristics associated with these
revenue streams can vary greatly. The server and professional services groups
can also experience fluctuations in gross margin as net revenues increase or
decrease since certain costs of revenues including technology, service, product
assembly and distribution act as fixed costs within certain volume ranges.

Cost of License Revenues

     Cost of license revenues includes royalties paid to certain software
vendors, amortization of acquired technologies, product packaging, documentation
and all costs associated with the acquisition of components, assembling of
finished products, warehousing and shipping. Cost of license revenues as a
percentage of license revenues decreased to 20% for the nine month period ending
June 30, 2000 from 22% in the same period of fiscal 1999. Cost of license
revenues as a percentage of license revenues decreased to 22% for fiscal year
1999 as compared to 27% for fiscal 1998. These decreases resulted from reduced
royalty rates and reduced technology costs together with the impact of stable
fixed costs over higher unit sales volume. In addition, material costs declined
as a result of increasing e-commerce trade.

Cost of Service Revenues.

     Cost of service revenues includes documentation, consulting and personnel
related expenses associated with providing such services. Cost of service
revenues was $14.4 million for the nine month period ended June 30, 2000 as
compared to $13.6 million for the same period of fiscal 1999. Cost of services
revenues for fiscal year 1999 was $18.6 million as compared to $16.8 million for
fiscal year 1998.

RESEARCH AND DEVELOPMENT

     SCO invests in research and development both for new products and to
provide continuing enhancements to current products of the server and
professional services groups. Research and development expenses increased 19% to
$23.0 million for the nine month period ending June 30, 2000 from $19.3 million
in the same period of fiscal 1999. The increase in research and development was
primarily due to increased spending associated with accelerating development of
Unixware 7. Research and development expenses decreased 12% to $25.8 million in
fiscal year 1999 as compared to $29.2 million in fiscal year 1998. Research and
development expenses represented 33% of net revenues for fiscal 1999 and 51% of
net revenues for fiscal 1998. The decrease in research and development expenses
during 1999 can be attributed to the diversion of research and development
resources to an outside funded research and development project.

SALES AND MARKETING

     Sales and marketing expenses increased 10% to $47.5 million, or 85% of net
revenues, for the nine month period ending June 30, 2000 as compared to $43.2
million, or 79% of net revenues, for the same nine month period of fiscal 1999.
The reason for the increase in spending can be attributed to an increase in
sales and marketing programs for Unixware products. Sales and marketing expenses
in fiscal year 1999 increased 18% to $60.0 million, or 78% of net revenues,
compared to $50.9 million, or 89% of net revenues, in fiscal year 1998. The
increase is due principally to an increase in the size of our direct sales force
and commissions as well as sales program costs that vary directly with increased
sales.

GENERAL AND ADMINISTRATIVE

     General and administrative expenses increased 5% for the nine month period
ending June 30, 2000 to $5.9 million, or 10% of net revenues, compared to $3.9
million, or 7% of net revenues, in the same period of fiscal 1999. The increase
in general and administrative expenses is primarily driven by the transfer of
certain staff from other functions due to the divisionalization of SCO. In
fiscal year 1999, general and administrative expenses increased by 2% to $5.1
million, or 7% of net revenues, compared to $5.0 million, or 9% of total net
revenues, in fiscal 1998. The fiscal 1999 increase was due to the movement of
certain staff to other functions.

FACTORS THAT MAY AFFECT FUTURE RESULTS

     The future operating results of the server and professional services groups
may be affected by various uncertain trends and factors which are beyond its
control. These include adverse changes in general economic conditions and rapid
or unexpected changes in the technologies affecting its products. The process of
developing new high technology products is complex and uncertain and requires
accurate anticipation of customer needs and technological trends. The industry
has become increasingly competitive and, accordingly, the server and
professional services groups results may also be harmed by the actions of
existing or future competitors, including the development of new technologies,
the introduction of new products, and the reduction of prices by such
competitors to gain or retain market share. The server and professional services
groups' results of operations could be harmed if it were required to lower its
prices significantly.

     The server and professional services groups participate in a highly dynamic
industry and future results could be subject to significant volatility,
particularly on a quarterly basis. The server and professional services groups'
revenues and operating results may be unpredictable due to shipment patterns.
The server and professional services groups operate with little backlog of
orders because its products are generally shipped as orders are received. In
general, a substantial portion of revenues of the server and professional
services groups have been booked and shipped in the third month of the quarter,
with a concentration of these revenues in the latter half of that third month.
In addition, the timing of closing of large license contracts and the release of
new products and product upgrades increase the risk of quarter to quarter
fluctuations and the uncertainty of quarterly operating results. Staffing and
operating expense levels of the

                                       91
<PAGE>   104

server and professional services groups are based on an operating plan and are
relatively fixed throughout the quarter. As a result, if revenues are not
realized in the quarter as expected, the expected operating results and cash
balances of the server and professional services groups could be harmed, and
such effect could be substantial and could result in an operating loss and
depletion of the cash balances of the server and professional services groups.

     The server and professional services groups experience seasonality of
revenues for both the European and the U.S. federal government markets. European
revenues during the quarter ending June 30 are historically lower or relatively
flat compared to the prior quarter. This reflects a reduction of customer
purchases in anticipation of reduced selling activity during the summer months.
Sales to the U.S. federal government generally increase during the quarter
ending September 30. This seasonal increase is primarily attributable to
increased purchasing activity by the U.S. federal government prior to the close
of its fiscal year. Additionally, net revenues for the first quarter of the
fiscal year are typically lower or relatively flat compared to net revenues of
the prior quarter.

     The overall cost of revenues may be affected by changes in the mix of net
revenue contribution between licenses and services, product families,
geographical regions and channels of distribution, as the costs associated with
these revenues may have substantially different characteristics. The server and
professional services groups may also experience a change in margin as net
revenues increase or decrease since technology costs, service costs and
production costs are fixed within certain volume ranges.

     Substantial portions of the revenues of the server and professional
services groups are derived from sales to customers outside the United States. A
substantial portion of the international revenues of SCO's United Kingdom
subsidiary are denominated in U.S. dollars, and operating results can vary with
changes in the U.S. dollar exchange rate to the United Kingdom pound sterling.
The revenues of the server and professional services groups may be affected by
general economic conditions in the United States, Europe and other international
markets. The server and professional services groups' operating strategy and
pricing take into account changes in exchange rates over time. However, the
results of operations of the server and professional services groups may be
significantly affected in the short term by fluctuations in foreign currency
exchange rates.

     The policy of the server and professional services groups is to amortize
purchased software and technology licenses using the straight-line method over
the remaining estimated economic life of the product, or on the ratio of current
revenues to total projected product revenues, whichever is greater. Due to
competitive pressures, it is reasonably possible that those estimates of
anticipated future gross revenues, the remaining estimated economic life of the
product, or both will be reduced significantly in the near future. As a result,
the carrying amount of the server and professional services groups' purchased
software and technology licenses may be reduced materially in the near future
and, therefore, could create an adverse impact on the server and professional
services groups' future reported earnings.

     SCO is aware of the issues associated with the new European economic and
monetary union (the "EMU"). One of the changes resulting from this union
required EMU member states to irrevocably fix their respective currencies to a
new currency, the Euro, on January 1, 1999. On that day, the Euro became a
functional legal currency within these countries. During the next two years,
business in the EMU member states will be conducted in both the 25 existing
national currencies, such as the Franc or Deutsche Mark, and the Euro. As a
result, companies operating in or conducting business in EMU member states will
need to ensure that their financial and other software systems are capable of
processing transactions and properly handling these currencies, including the
Euro. SCO has done a preliminary assessment of the impact the EMU formation will
have on both the internal systems and the products of the server and
professional server groups and has commenced appropriate actions. SCO has not
yet determined all of the cost related to addressing this issue, and there can
be no assurance that this issue and its related costs will not harm the server
and professional services groups, business, operating results and financial
condition.

LIQUIDITY AND CAPITAL RESOURCES

     Cash and cash equivalents as of June 30, 2000 and September 30, 1999 were
$832,000 and $2.2 million respectively. Historically, SCO has managed cash and
cash equivalents on a centralized basis. Cash receipts associated with the
server and professional services groups' business except for amounts arising
from specific research and development funding contracts have been transferred
to SCO on a daily basis and SCO has funded the server and professional services
groups' disbursements.

     Net cash used in operations during the nine months ended June 30, 2000 and
the years ended September 30, 1999 and 1998 was $39.6 million, $32.7 million and
$46.0 million respectively. Cash used in operations during each of these periods
resulted primarily from net losses of $44.4 million, $46.6 million and $57.0
million offset by depreciation and amortization of $8.7 million, $11.4 million
and $13.9 million respectively. Net changes in operating assets and liabilities
resulted in a net usage of cash of $3.7 million in the nine months ended June
30, 2000, cash generated of $3.0 million during the year ended September 30,
1999 and cash usage of $3.2 million in the year ended September 30, 1998.

     Cash used in investing activities during the nine months ended June 30,
2000 and the years ended September 30, 1999 and 1998 was $2.8 million, $6.3
million and $4.1 million, respectively. Cash used in investing activities was
represented by investment in fixed assets and the purchase of software and
technology licenses for use with our products.

     Cash provided by financing activities was $41.0 million, $41.3 million and
$50.1 million during the nine months ended June 30, 2000 and the year ended
September 30, 1999 and 1998 respectively. This came from advances from SCO
totalling $45.1 million, $47.1 million and $51.6 million offset by payments made
under capital leases and decreases in other long term liabilities.

     The server and professional services groups has been and will continue to
be dependent upon funding from SCO in order to finance losses incurred in
operations. Management expects to require additional funding from SCO during the
year ended June 30, 2001 and has received a commitment from them to continue
funding until that date. There can be no assurance that SCO will provide
additional funding after this date. In the event that SCO is unwilling to
provide additional funding there can be no assurance that alternative funding
will be available on acceptable terms or at all.

     SCO has incurred losses from operations of approximately $37.1 million
during the nine months ended June 30, 2000 and revenues have declined from
$165.5 million for the nine months ended June 30, 1999 to $116.1 million for the
nine months ended June 30, 2000. SCO has recently announced cost reduction plans
in order to reduce operating expenses to levels consistent with current revenues
and is investigating financing alternatives. There can be no assurance that such
cost reduction measures or such financing will be available, if at all, on terms
acceptable to SCO.

     In conjunction with the combination, The Canopy Group, Inc., a major
stockholder of Caldera Systems, Inc., has agreed to loan up to $18.0 million to
SCO. Further, Caldera Systems, Inc. has agreed to loan $7.0 million to SCO in
the form of a short-term note repayable at the consummation of the transaction
between SCO and Caldera Systems, Inc.

RECENT ACCOUNTING PRONOUNCEMENTS

     In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133 (SFAS 133), Accounting for Derivative
Instruments and Hedging Activities, which establishes accounting and reporting
standards for derivative instruments and hedging activities. It requires that an
entity recognize all derivatives as either assets or liabilities in the
statement of financial position and measure those instruments at fair value. In
June 1999, the FASB issued Statement of Financial Accounting Standards No. 137
(No. 137), Accounting for Derivative Instruments -- Deferral of the Effective
Date of SFAS Statement No. 133. SFAS 137 defers the effective date of SFAS 133
until June 15, 2000. Management does not believe this will have a material
effect on the financial statements of

                                       93
<PAGE>   106

the server and professional services groups. The server and financial services
groups will adopt SFAS 133 as required in fiscal year 2001.

     In June 2000, the Financial Accounting Standards Board issued Financial
Accounting Standard No. 138 (FAS 138), Accounting for Certain Derivative
Instruments -- an amendment of FAS 133, Accounting for Derivative instruments
and Hedging Activities. FAS 138 shall be effective for all fiscal quarters of
all fiscal years beginning after June 15, 2000. SCO does not expect this to have
a material impact on the financial position and results of operations of the
server and professional services groups.

     In March 2000, the Financial Accounting Standards Board (FASB) issued FASB
Interpretation No. 44, Accounting for Certain Transactions Involving Stock
Compensation -- an interpretation of APB Opinion No. 25. FIN 44 clarifies the
application of Opinion 25 for (a) the definition of employee for purposes of
applying Opinion 25, (b) the criteria for determining whether a plan qualifies
as a noncompensatory plan, (c) the accounting consequence of various
modifications to the terms of a previously fixed stock option or award, and (d)
the accounting for an exchange of stock compensation awards in a business
combination. FIN 44 is effective July 1, 2000, but certain conclusions cover
specific events that occur after either December 15, 1998, or January 12, 2000.
The adoption of the conclusions covering the specific events after either
December 15, 1998 or January 12, 2000 did not have a material effect on the
financial position or results of operations of the server and professional
services groups. Management believes that the impact of the remaining provisions
of FIN 44 will not have a material effect on the financial position or results
of operations of the server and professional services groups.

     In December 1999, the Securities and Exchange Commission ("SEC") issued
Staff Accounting Bulletin No. 101 (SAB 101), Revenue Recognition in Financial
Statements, which provides guidance on the recognition, presentation and
disclosure of revenue in financials filed with the SEC. SAB 101 outlines the
basic criteria that must be met to recognize revenue and provides guidance for
disclosures related to revenue recognition policies. SCO must adopt SAB 101 in
the first quarter of fiscal 2001. Management believes that the impact of SAB 101
will not have a material effect on the financial position or results of
operations of the server and professional services groups. However, the
interpretation of SAB 101 is still under discussion by the Securities and
Exchange Commission and may be revised. Such revisions could have a material
effect on the financial position or results of operations of the server and
professional services groups.

                              BUSINESS OF CALDERA

OVERVIEW

     Caldera enables the development, deployment and management of Linux
specialized servers and Internet access devices that simplify computing. Our
Linux software products and service offerings are specifically designed to meet
the complex needs of eBusiness, or business over the Internet. During 1999 and
the first six months of 2000, our OpenLinux technology received many awards and
recognitions, including Linux Magazine's Emperor Award, Internetweek's Best of
the Best, The Linux Show's Best Distribution of Millennium, Linux Journal's
Product of the Year award at Comdex and Network Computing's Well-Connected Award
for Best Network Operating System. We facilitate the adoption of Linux by
providing educational programs designed to help our customers to develop, deploy
and administer Linux systems. We embrace the open source model and participate
as a key member of many open source, industry standards and partner initiatives,
including Linux Professional Institute, Linux Standards Base and Linux
International Group. We primarily distribute our products and services through
our indirect distribution channel model. Our customers include AST Computers,
Cendant, First International Computers, Gates/Arrow, IBM, Ingram Micro,
MediaGold, MTI Technology Corporation, Navarre Corporation, Support Net and Tech
Data.

INDUSTRY BACKGROUND

     The Internet has accelerated the introduction of processes for managing
information, providing services and solutions and handling customers and has
changed the way software applications are developed and deployed. These
processes enable companies to utilize the Internet to extend their businesses
closer to their customers, partners and suppliers and to communicate more
effectively with employees. The Internet has also enabled and accelerated a
trend towards distributed software applications. With a distributed application,
instead of installing and running software on an individual desktop, end-users
can access the application from remote locations using the Internet. The
Internet makes the physical location of a software application or service
irrelevant to the end-user. Rather than individually installing programs on a
number of PCs, businesses can use the Internet to allow end users to access a
single server maintaining the software. As a result of this trend, application
service providers, or ASPs, have emerged. An ASP is a service provider that
centrally hosts services and software applications and leases them to companies.
These companies can access these applications for a fee through the Internet,
rather than buying and installing the programs. However, operating under
previous computing models, many companies have already invested tremendous
amounts of capital in their existing legacy computer systems and applications.
Therefore, new software applications must be developed to allow seamless
integration between existing legacy systems and applications being offered by
ASPs over the Internet.

     Another trend in distributed applications is the advent of thin appliance
servers, or specialized servers. These specialized servers perform specific
applications, such as file and print sharing, secure Internet services, backup
services and electronic mail services. Companies are realizing that they can
deploy efficient, discrete applications on specialized servers and do not need
to install massive, costly, multi-functional systems merely to install a new
application or add a particular function. Companies have started using
specialized servers to administer the new eBusiness software applications that
are emerging. Having separate servers for each application improves performance
and increases stability, while decreasing overall operating and maintenance
costs.

     In addition, the proliferation of information on the Internet has driven
the need to customize information for individual use. As a result, manufacturers
have developed ways to separate the visual elements of a standard PC program
from its computing functions, allowing most of the computing function to be
performed remotely. This has facilitated the creation of alternative Internet
access devices for individuals, such as personal digital assistants,
Internet-capable cellular telephones and television set-top boxes. These
Internet access devices are far less costly than personal computers and allow
more users

                                       95
<PAGE>   108

access to the Internet and the ability to participate in eBusiness. Internet
devices are becoming popular worldwide as a way of getting businesses and
consumers connected to the new eBusiness economy.

     The trend towards distributed software applications and specialized servers
and the proliferation of Internet access devices have increased companies'
ability to conduct eBusiness and consumers' access to eBusiness. The dynamic and
fast changing nature of eBusiness requires an operating system, the software
that enables a computer and its various components to interact, that can change
with the accelerated evolution of eBusiness. The optimal operating system must
enable companies to connect specialized servers and Internet access devices to
the Internet network to conduct eBusiness. It must be customizable to adapt to
the changing software applications environment, shifting hardware
infrastructures and emergence of new Internet access devices. It must be
scalable to accommodate the growing number of users and the ways that they
access the Internet. The optimal operating system must be highly stable and easy
to maintain to minimize overall operating and maintenance costs. It must allow
for rapid deployment and development and be easily upgradeable to keep pace with
the changing needs of eBusiness. Finally, this operating system must interface
with existing systems and embrace open technical and communications standards
like Java and extensible mark-up language, or XML, to take full advantage of the
Internet.

     Linux is an operating system well-suited for eBusiness. The term open
source applies to software that has its internal source code open to the public
for viewing, copying, examining and modification. As a result, the Linux source
code is available for download over the Internet. Open source code allows
thousands of developers around the world to continually collaborate to improve
and enhance the software. The Internet has facilitated and greatly enhanced this
collaborative environment.

     - comprehensive Internet functionality;

     - flexibility and customizability;

     - high scalability;

     - stability;

     - interoperability with multiple systems and networks;

     - multi-appliance capability, including Internet access devices;

     - low acquisition and maintenance costs; and

     - compliance with technical and communications standards.

     Despite these benefits, Linux as an open source system is not without
drawbacks. Linux has not yet been widely adopted by business due to:

     - the absence of Linux products tailored for business;

     - the fragmentation of Linux offerings;

     - inadequate education and training;

     - the lack of proper distribution channels for Linux solutions;

     - the lack of technical knowledge and support;

     - difficulty in management and deployment; and

     - the limited number of applications available for use on Linux.

     Historically, business users have lacked a Linux solution that suits their
needs. For Linux to fully support eBusiness, a solution must consist not only of
advanced technology but also should be enhanced and tailored for business. This
solution must promote the benefits of Linux for eBusiness and provide the proper
education and training to facilitate adoption. Proper distribution channels are
required to facilitate access to the business user. The Linux for eBusiness
solution must be able to accommodate business applications and be able to
interoperate properly with the diverse environment of internal corporate

                                       96
<PAGE>   109

information systems and the Internet. It must have the flexibility to be
maintained centrally or managed remotely. Finally, a solution must adhere and
conform to commercial standards to incorporate the latest technological
advancement and ensure wide acceptance.

THE CALDERA SYSTEMS SOLUTION

     We develop and market software based on the Linux operating system and
provide related services that enable the development, deployment and management
of Linux specialized servers and Internet access devices that simplify
computing. We believe that our Linux solution is a comprehensive solution for
eBusiness. Key benefits of our solution include:

     Focused business framework.  We believe we were the first to tailor Linux
open source code from various sources into sound discrete products that are
usable, deployable and manageable for eBusiness. Our development team consists
of experienced Linux engineers and business professionals. We develop our
products by first carefully choosing the Linux features that are the most
relevant and useful for eBusiness. Then we assemble the code so that it is
logically arranged and works together as seamless applications in which source
and binary code match for logic and order. Our products are then tested for
quality and performance. This enhances reliability and reduces the need for
technical support when used under strenuous business conditions. This process,
known as self-hosting, is unique in the Linux community and accounts for the
high levels of stability and performance of our products. Our products are also
designed to be interoperable with multiple platforms to enable businesses to
make efficient use of existing information technology investments.

     Effective distribution channel.  We provide products and services to the
people who serve the business community. Most of our products that are purchased
by corporate information systems departments are sold through our distribution
channel to electronic solution providers. We define electronic solution
providers to include value added resellers, or VARs, original equipment
manufacturers, or OEMs, Internet service providers, or ISPs, corporate
information technology managers and partners, ranging from independent local
technical specialists to large system integrator organizations, that offer
value-added solutions for eBusiness. Business customers often rely on solution
providers to recommend which technology to purchase. We provide solution
providers with products, third-party applications, education, training and tools
to effectively facilitate or offer a Linux solution for eBusiness. Solution
providers benefit from the lower maintenance and support costs necessary to
maintain our Linux solution. We offer our services to solution providers on a
worldwide basis.

     Comprehensive product offerings.  We believe that our OpenLinux technology
is the most advanced for eBusiness. OpenLinux is the technology foundation on
which we are able to build multiple products that perform different tasks. Each
product has specific components that can be modified. For example, our desktop
product can be modified to perform client specific functions such as running
business automation applications or accessing the Internet as an email client on
hand-held appliances. Our server product contains modular components that can be
configured to run specialized servers such as an email server or a Web site
server. We continually enhance the OpenLinux technology through our development
centers in Germany and the United States. As a result, we are able to
incorporate the latest Linux enhancements or modifications into our products.
Our business experience enables us to build relevant business enhancements to
Linux through add-on segments of code that connect to the core source code.
These enhancements include Web administration applications, the Caldera Systems
open administration system, and an easy-to-use Linux installation wizard. We
also offer our products in multiple language versions.

     Complementary value-added services.  In order for businesses to implement
our product offerings, we provide a wide range of valuable services. We believe
that our service offerings provide significant benefits for eBusiness. These
service offerings include:

     - Technical Support -- Our technical support provides assistance during
       installation and operation of OpenLinux;

                                       97
<PAGE>   110

     - Consulting and Custom Development -- Our consultants have extensive
       technological and business knowledge, which allows us to assist our
       electronic solution provider customers in implementing Linux solutions;

     - Hardware Optimization and Certification -- Our consultants can optimize
       OpenLinux for a specific hardware platform and provide a rigorous testing
       and certification process; and

     - Documentation -- We provide consistent and up-to-date documentation on
       Linux that is not readily available in the open source development
       community.

     Comprehensive, distribution-neutral education and training. Many companies
are delivering different versions of Linux called distributions. We provide a
comprehensive distribution-neutral training program for Linux. Our courses focus
on educating and training the business community on Linux's benefits for
business use. We offer a comprehensive set of courses designed to prepare
students to develop, deploy and manage Linux in a business environment,
including system, network and Internet administration and programming. A student
who has successfully completed our courses will be proficient with the leading
distributions of Linux. We offer high-quality instructor-led training through
our own training center at our headquarters and also offer our educational
programs indirectly through our Caldera Open Learning Providers around the
world.

     Business community catalyst and open source advocate. We believe we were
the first Linux provider to introduce an open source operating system designed
for the business environment. By demonstrating to key information technology
companies such as Corel and Netscape that open source systems can work well with
proprietary systems, we believe that we have sparked the interest of more
conservative technology adopters and accelerated acceptance of Linux for
business use. We help port, or convert, business applications to the Linux
platform and offer ways to incorporate those products into existing systems. We
are a major driver of Linux standards based initiatives such as Linux
Professional Institute, or LPI, an independent organization dedicated to the
establishment of professional certification standards for Linux professionals,
and Linux Standards Base, or LSB, an initiative that is designed to standardize
application development for the Linux platform. An application that meets all
the criteria for LSB should work on all compliant distributions of Linux. If LSB
is widely adopted, we believe it will significantly reduce the fragmentation of
Linux.

     We fully embrace the open source model and continuously contribute tools
and technology to the open source community. We give away CD ROMs containing our
Linux operating system at trade shows and allow it to be freely downloaded from
the Internet to encourage interest. We foster multiple development projects over
the Internet and help each project progress smoothly.

SOFTWARE PRODUCTS

     We develop, market and support Linux products and solutions specifically
designed to meet the complex needs of eBusiness. According to PC Data, during
1999, Caldera Systems was third in sales of Linux operating systems in the
United States, both in terms of units sold and aggregate dollar amount. Our
products and solutions integrate both commercial and open source software
products developed by us and third parties. For example, we have included
applications that we have open sourced, such as LInux wiZARD (LIZARD), our
award-winning graphical Linux step-by-step installation tool. We apply
development and testing procedures to the open source code included in our
products similar to those procedures applied to commercial products. This
process known as self-hosting is unique in the Linux community and accounts for
the high levels of stability and performance of our products. Our rigorous
development procedures result in a highly consistent product that enables easier
and more rapid customization, integration and support of our solutions. Our
products are designed to work both individually and together to provide a
rapidly expandable platform as enterprises extend their eBusiness
infrastructure.

OpenLinux eDesktop 2.4

     We first released our principal product, OpenLinux, a Linux operating
system, in calendar year 1995. In March, 2000, we began shipping our newest
update of OpenLinux, OpenLinux eDesktop 2.4. OpenLinux eDesktop 2.4 is an
integrated and pre-tested collection of approximately 300 business-relevant
third-party software components, which provide for a variety of functions that
can be utilized either on a single desktop computer or in a networked
environment. We have historically developed OpenLinux for the first-time Linux
user, which predominantly has come from a Windows, desktop environment.
OpenLinux eDesktop 2.4 is currently available for the Intel and Sun SPARC
platforms. Examples of some of the key components of OpenLinux eDesktop 2.4 and
the functions they perform include:

          IBM                                             Tech Data
</TABLE>

     Navarre Corporation and Frank Kasper & Associates each accounted for more
than 10% of our revenue in fiscal 1999. Navarre Corporation was the only
customer that accounted for more than 10% of our revenue in the nine months
ended July 31, 2000. Substantially all of the revenue we have received from
these two parties reflects revenue from sales of our Linux products.

STRATEGIC TECHNOLOGY ALLIANCES

     We have business alliances with key global industry partners, including
Citrix Systems, Fujitsu, IBM, Intel, Novell, Oracle and Sun Microsystems. These
relationships encompass product integration, two-way technology transfers,
channel partnerships and revenue generating initiatives in areas of product
bundles, training and education, consulting and third-level technical support
for our partners. The objectives of these partnerships include:

     - providing complete hardware and software Linux solutions;

     - licensing our education materials to be used in our partners' training
       centers;

     - supporting our partners' Linux engineering efforts as well as their
       end-user customers; and

                                       101
<PAGE>   114

     - mutually developing our sales and distribution channel by coordinating
       marketing initiatives in creating demand for our products.

     These relationships are non-exclusive, leaving us opportunities to explore
other strategic partnerships on a global level. In particular, in January 2000,
we entered into license agreements with Sun Microsystems which allow us to
create and commercially distribute applications developed utilizing Java2
Standard Edition for Linux, Java HotSpot Performance engine, EmbeddedJava and
PersonalJava for use on the Itanium (Merced), PowerPC, Sun x86, and UltraSPARC
processors. These licenses are non-exclusive. In connection with the licenses
relating to the Java2 Standard Edition and the Java HotSpot Performance Engine,
we paid Sun Microsystems $1.3 million.

     Furthermore, in November 1999, we entered into a contributor agreement with
Intel to port OpenLinux products, including OpenLinux eServer, to Intel's IA64
platform. In addition we will be porting the Java Development Toolkit and Java
Runtime Environment to the IA64 platform.

INDUSTRY PARTICIPATION

     We participate as a key member of many industry standard, partner and open
source initiatives, including the following:

     - Linux Professional Institute, an independent organization dedicated to
       the establishment of professional certification standards for Linux
       professionals;

     - Linux Standards Base, a Linux community initiative dedicated to
       addressing problems and defining standards associated with the many
       versions of Linux distributions currently in the marketplace;

     - Linux Internationalization Group, a voluntary Linux community working
       group, of which we are one of the founding members, dedicated to
       addressing interoperability, internationalization and localization of
       Linux applications in the international context;

     - IA64 Linux Project, an Intel-sponsored initiative to port the Linux
       kernel to the Intel Itanium processor;

     - Distributed Management Task Force, an independent organization including
       most of the largest software and systems vendors in the world, dedicated
       to creating new standards for computer systems management. We are working
       with this task force to incorporate into our OpenLinux products
       commonality standards already in place among enterprise-level businesses;
       and

     - Java, Sun Microsystem's proprietary software programming language. We
       plan to incorporate standards that will allow the majority of current
       Java applications to run on Linux and to provide for developers to create
       new applications in Java for use on Linux.

SALES, MARKETING AND DISTRIBUTION

     Our focus on Linux for eBusiness enables us to promote the development,
deployment, and management of Linux appliances and devices that facilitate the
eBusiness infrastructure. Our primary strategy has been to distribute our
products and services through our indirect distribution channel model.

     The majority of our revenue comes from distributors. As of July 31, 2000,
we had approximately 38 distributors worldwide who purchase directly from us.
These distributors in turn sell to approximately 4,000 retail outlets in the
United States and approximately 900 equivalent sites internationally. On a
worldwide level, we utilize over 700 VARs to promote technology and service
integration of our products and solutions to their end-user business customers.

     For the fiscal year ended October 31, 1999, our distributor channel
represented 74% of our total software and related products revenue and included
distributors such as Frank Kasper & Associates, Ingram Micro, Navarre
Corporation and Tech Data, domestically, and MediaGold in Europe. Sales through
this distributor channel represented 67% of our total software and related
products revenue for the

                                       102
<PAGE>   115

nine months ended July 31, 2000. We plan to continue to recruit new distributors
to introduce OpenLinux technology into new markets, including into foreign
countries with language specific products.

     We sell directly to OEM partners, including AST Computers in the United
States and First International Computers in Taiwan. These arrangements are
typically royalty-based and our revenue is determined by volume of OpenLinux
products shipped on our partners' hardware or bundled together in distribution.

     Our marketing efforts support our sales and distribution efforts,
promotions and product introductions and include marketing development funds to
push OpenLinux products. Pull marketing, apart from delivering quality products
and services needed in the marketplace, is focused on branding, solutions,
advertising, tradeshows, press releases, white papers and marketing literature.
We focus our marketing on public relations and press relations extensively to
communicate the progress we are making in the business arena. In particular, our
marketing strategy consists of:

     - branding "Linux for eBusiness" through public relations announcements and
       advertising;

     - announcing technology and solution awards;

     - creating an effective partner program to generate brand awareness and
       promote our products; and

     - increasing public awareness through speaking engagements at strategic
       tradeshows and conferences worldwide and participating in technology
       forums.

     Our Web site, www.calderasystems.com, is focused on strengthening our Linux
for eBusiness strategy. In addition to allowing visitors to download free
software, our Web team is expanding our current Web strategy of branding, direct
sales through our online store and linking customers to channel partners.
Through our Web site, we plan to join together ISVs, hardware partners,
customers, channel players, developers, ISPs and other Linux players who want to
connect for business reasons and to generate royalties based on introductions,
advertising and transactions.

COMPETITION

     The market for eBusiness solutions is emerging rapidly and is therefore
intensely competitive, characterized by rapidly changing technology and evolving
standards. We expect competition to increase both from existing competitors and
new market entrants. We face direct competition in the area of specialized
servers and Internet devices from other providers of solutions for specialized
servers. We also face competition from traditional, non-Linux operating systems,
other Linux operating systems, technical support providers and professional
services organizations.

     Companies currently offering software solutions for specialized servers or
Internet access devices include Berkeley Software Design, Microsoft and a joint
venture involving SCO and Compaq which is included in the server and
professional services group. Cygnus Solutions, VA Linux and Wind River provide
similar solutions embedded into their hardware offerings. In addition, Sun
Microsystems has announced plans to open source its Solaris Unix operating
system in an attempt to attract more developers to the platform. Many of these
competitors are large, well-established companies with significantly greater
financial resources, more extensive marketing and distribution capabilities,
larger development staffs and more widely recognized brands and products.

     Companies currently offering competitive non-Linux operating systems
include providers of hardware-independent multi-user operating systems for Intel
platforms, such as Microsoft, IBM and Novell. They also include providers of
proprietary versions of the UNIX operating system, such as AT&T, Compaq,
Hewlett-Packard, IBM, Olivetti, Sun Microsystems and Unisys. These competitors
often bundle their operating systems with their hardware products, creating an
additional barrier for us to overcome in penetrating their customer bases. There
are also significantly more user applications available for competing operating
systems, such as Windows NT and UNIX, than there are for Linux operating
systems.

                                       103
<PAGE>   116

     In the Linux operating system market, our competitors include Corel,
MacMillan, Red Hat, SuSE and TurboLinux. Several of these competitors have
established customer bases, strong brand names and continue to attract new
customers. Red Hat, in particular, has had more visibility and a stronger brand.
In addition, this market is not characterized by the traditional barriers to
entry that are found in most other markets, due to the open source nature of our
products. For example, anyone can readily download the Linux kernel and packages
from the Internet, optimize and add value to it, and thereafter market their own
version of the Linux operating system. Similarly, anyone can copy, modify and
freely redistribute the open source components of OpenLinux. Accordingly, new
competitors or alliances among competitors may emerge and rapidly acquire
significant market share. Our product, however, is specifically suited for and
targeted toward the requirements of business. In addition, our education and
training program is more pervasive and our distribution channel is more
developed and mature. We believe that these three key advantages give us a
competitive advantage in the Linux operating system market.

     We also compete for service revenue with a number of companies that provide
technical support and other professional services to users of Linux operating
systems, including some original equipment manufacturers with which we have
agreements. Many of these companies have larger and more experienced service
organizations than we do. We also may face competition on this front from
companies with larger customer bases and greater financial resources and name
recognition, such as Corel, Cygnus Solutions and Sun Microsystems, which have
indicated interest in the Linux operating systems market.

     Based upon these market factors, we believe that the most significant
criteria affecting the competitive landscape for our products include:

     - networking capability;

     - distribution strength;

     - market perception of vendor;

     - education and training;

     - ease of customization;

     - commercial development process;

     - product performance, functionality and price;

     - education and training;

     - ease of use;

     - breadth of hardware compatibility;

     - quality of support and customer services;

     - strength of relationships in the open source community; and

     - availability of user applications.

     We believe that we compete favorably with many of our competitors in a
number of respects, including product performance, functionality and price,
networking capability and breadth of hardware compatibility. To solidify and
improve our competitive ability, our near-term strategy is to strengthen our
existing strategic relationships and enter into new ones in an effort to enhance
our name recognition, expand our distribution capabilities and attract more
attention to the open source movement, which in turn should create additional
incentives for software developers to write more applications for OpenLinux.

SOFTWARE ENGINEERING AND DEVELOPMENT

     We have invested and will continue to invest in the development of
innovative new product features and technologies in response to the evolving
market for Linux solutions and input from key customers. We seek to deliver
consistently strong Linux products targeted at specific usage as opposed to the
more

                                       104
<PAGE>   117

traditional one-size-fits-all Linux distribution in which the customer may be
required to re-build the kernel to attain the proper configuration. This product
segmentation of eServer and eDesktop allows us to tailor the delivery of the
product to work optimally as installed off the CD, yet continue to provide
customization, one of the essential values of Linux.

     One of our key strategies has been to focus on identifying and removing the
traditional barriers for mass deployment of UNIX-style operating systems (e.g.,
installation, system configuration and management). The delivery of the
award-winning LIZARD installation system, initially shipped in OpenLinux 2.2 in
April 1999, successfully paved the way for a much broader base of users to
experience Linux with a much lower learning curve. Going forward, we intend to
continue to apply this philosophy as we work toward addressing the broader
issues of system configuration management and administration, specifically as it
pertains to the deployment of eServer-based information appliances and eDesktop
platforms. Our latest component of this architecture, the LUI (Linux Unattended
Install) was developed in cooperation with a large European University to allow
many systems (eServer or eDesktop) to be installed and upgraded without
requiring direct user interaction. We intend to introduce new components with
each subsequent product.

     Our major commitment in the area of research is how to extract the
management aspects of individual systems, new and legacy applications to enable
the deployment, management and administration of platforms and applications to
be handled from anywhere on the network. Leveraging Linux, open source and open
standard technologies is a way of providing necessary infrastructure components.
We believe that contributing back to Linux much of our research will facilitate
more of an industry standard as well as industry cooperation.

     Our product development process is modeled to standard, commercial software
engineering practices. We apply these practices to both documentation and
procedures to ensure consistent product quality. As a result, we are able to
offer our platform products to OEM customers in several configurations without
significant effort. We are also able to move our platform products efficiently
to new processor platforms as new business opportunities arise.

     As of July 31, 2000, we employed an in-house engineering staff of 56 in
addition to maintaining a contract consulting arrangement with a Japanese firm
for product development needs specific to the Japanese market. The engineering
staff consists of two primary teams, the U.S. Engineering group located near
corporate headquarters in Utah and the European group located in Erlangen,
Germany. Our staff members possess a broad range of both Linux and other
industry experience.

INTELLECTUAL PROPERTY

     Our success depends significantly on our ability to protect our trademarks,
trade secrets, and certain proprietary technology. To accomplish this, we rely
primarily on a combination of trademark and copyright laws and trade secrets. We
also require that our employees and consultants sign confidentiality and
nondisclosure agreements. We generally regulate access to and distribution of
our documentation and other proprietary information.

     Certain components of OpenLinux have been developed and made available for
licensing under the GNU General Public License and similar licenses, which
generally allow any person or organization to copy, modify and distribute the
software. The only restriction is that any resulting or derivative work must be
made available to the public under the same terms. Therefore, although we retain
the copyrights to the code that we develop ourselves, due to the open source
nature of our software products and the licenses under which we develop and
distribute them, our collection of trademarks constitutes our most important
intellectual property.

     We own the registered trademark "CALDERA(R)" and also have license rights
relating to "CALDERA SYSTEMS(TM)", a pending trademark application. In September
1999, the United States Trademark office registered our applications for
"OpenLinux(TM)" and "Linux for Business(TM)". We filed our response with respect
to the rejection of the "OpenLinux" trademark on March 28, 2000. Our trademark

                                       105
<PAGE>   118

application for "Linux for Business" was suspended on April 24, 2000, pending
disposition of prior applications.

     Despite our efforts to protect our trademark rights, unauthorized third
parties have in the past attempted and in the future may attempt to
misappropriate our trademark rights. We cannot be certain that we will succeed
in preventing the continued misappropriation of our tradename and trademarks in
these circumstances or that we will be able to prevent this type of unauthorized
use in the future. The laws of some foreign countries do not protect our
trademark rights to the same extent as do the laws of the United States. In
addition, policing unauthorized use of our trademark rights is difficult,
expensive and time consuming. The loss of any material trademark or trade name
could have a significant negative effect on our business, operating results and
financial condition.

     We do not believe that our products infringe the rights of third parties.
However, our products are comprised of many distinct software components,
developed by many independent parties, and therefore third parties have in the
past asserted, and may in the future assert infringement claims against us which
may result in costly litigation or require us to obtain a license to third-party
intellectual rights. There can be no assurance that such licenses will be
available on reasonable terms or at all, which could have a negative effect on
our business, operating results and financial condition.

EMPLOYEES

     As of July 31, 2000, we had a total of 209 employees. Of the total
employees, 56 were in software engineering, 79 in sales and marketing, 21 in
customer service and technical support, 13 in operations and 40 in finance and
administration. From time to time we also employ independent contractors to
support our professional services, product development, sales, marketing and
business development organizations. Our employees are not represented by any
labor union and are not subject to a collective bargaining agreement, and we
have never experienced a work stoppage. We believe our relations with our
employees are good.

FACILITIES

     Our principal executive office is currently located in Orem, Utah where we
lease approximately 45,531 square feet of office space. Our annual rental
expense under the lease is approximately $664,080. We sublet a 6,360 square foot
portion of that space to two other companies for approximately $10,000 per
month. We also occupy an additional office facility in Orem, Utah, under a lease
that costs $8,990 per month and 5,544 square feet of warehouse space in Orem,
Utah, under an 18 month lease that costs approximately $32,000 per year. Our
German subsidiary occupies 3,375 square feet in Erlangen, Germany under a
five-year renewable lease for approximately $4,880 per month. This lease expires
September 1, 2004, and additional space is available under similar terms. We
believe that our existing facilities are adequate for our current requirements
and that additional space can be obtained on commercially reasonable terms to
meet our future requirements.

LEGAL PROCEEDINGS

     We are not a party to any material legal proceedings.

              BUSINESS OF SERVER AND PROFESSIONAL SERVICES GROUPS

OVERVIEW

     The server and professional services groups operate as a global leader in
server software for networked business computing, and the world's leading
provider of UNIX server operating systems. The business of the server group was
begun over 20 years ago by AT&T and focuses on developing and marketing UNIX
server software that runs on standard Intel hardware systems. The server group
supplies the system software for approximately 80% of all UNIX servers on Intel
platforms and approximately 40% of all UNIX servers for all hardware platforms.
The professional services group complements the server group and provides
professional services to implement and maintain UNIX system software products.

THE SERVER AND PROFESSIONAL SERVICES SOLUTION

     The server and professional services groups' mission is to create, market
and support the server software that system builders choose for networked
business computing. The server and professional services groups believe that
server-based network computing enables businesses to improve their customer
information flow and business transaction efficiencies. Key elements of the
groups' strategy are:

     - Leverage large global installed base;

     - Effective distribution channel;

     - Focussed product offerings; and

     - Leverage professional services to complement server product line.

The server and professional services groups believe that companies that adopt a
server-based network computing model can understand their customers better,
reach wider potential markets, bring products to market faster and improve their
overall customer satisfaction levels. With server-based computing and products
and services, IT professionals can immediately leverage their existing
investments, deploy applications faster and dramatically cut the cost of the
systems administration and management.

     The server products are used by enterprises of all sizes. These enterprises
and their characteristic usage of server products are divided into the following
market segments:

     - Small to Medium Enterprise -- Processing which is confined to one or a
       few small servers, typically in a single physical location per small or
       medium sized enterprise;

     - Replicated Site -- Processing which is replicated onto many small servers
       within a large enterprise, typically located across hundreds or thousands
       of physical sites in a given enterprise; and

     - Large Enterprise -- Processing which is shared across one or a few medium
       to large sized servers (or clusters of servers) for use by many people
       across an entire large enterprise and/or between many people across
       several enterprises.

The Server Group's Large Installed Base

     The Server Group has a large installed base of over 2 million licensees
worldwide, which include small to medium enterprises, replicated sites, and
large enterprises.

     Small to medium enterprises provide the server and professional services
groups with many opportunities to gain a major market share in vertical market
places such as pharmacies, lumber merchants or building access control systems.

     Replicated sites produce recurring revenue stream from upgrades and
incremental systems deployment. Once the initial contract is awarded, there are
also incremental opportunities to add new systems to augment capabilities of the
user's network, including e-business applications and other new product
features. Since the sites are dispersed and there is a need for high reliability
with low operator invention, these customers are less inclined to change the
system basis.

     SCO operating systems have also been in-built into many products such as
voice mail systems, telephone switches and badge or ticket readers. A
characteristic of this market is very slow adoption of alternative technologies.
Once development of a product is complete, the systems will often have a
marketing life of many years. These in-built systems continue to provide a
regular source of revenue and potential for new solutions with existing
customers. Examples of these systems include:

     - Private telephone exchanges from Siemens and Lucent;

     - Voice mail systems from Lucent;

     - Voice response systems from Wildfire;

     - Cable television controllers from Scientific Atlanta; and

     - Automobile testers from BMW.

     When SCO acquired the UNIX business from Novell in December, 1995, it also
assumed the legacy of many systems installed over the years by companies such as
Unisys, ICL, Olivetti, NCR and Siemens. Many of these systems were upgraded
during the year 2000 conversion process to SCO Server products and have now
transitioned to become server group customers. The group believes these
customers will continue to provide steady streams of revenue for many years.

SERVER PRODUCTS

     The server group is a vendor of UNIX operating systems for Intel-based
computers and serverware, networking software, development tools, and utilities
to be used with SCO UNIX operating systems. Server products are primarily used
on computers, which support the integration of information, communication and
processing from more than one person. These products are used as a system
software environment for the support of application software, whether the
applications are processed on a single computer, within a cluster of computers,
or across a network of computers.

UnixWare 7

     The UnixWare 7 operating system is designed to support distributed network
computing on Intel processor-based servers. Running on the new generation of
"enterprise-class" Intel processors, UnixWare 7 delivers power, value and
versatility to businesses of all sizes, permitting companies to simplify and
increase business operations and better understand customers' needs.

PROFESSIONAL SERVICES

     The group primarily offers the following services:

     - Consulting. These services include assessment services to help a customer
       understand and identify its needs and strengths prior to the use of the
       Server products, and assisting customers in developing complete solutions
       for their needs.

     - Custom software development. These services typically involve customizing
       the products sold to a customer to support a customer's proprietary
       system or configuration.

     - Optimization. These services typically involve configuring a customer's
       system and the products sold to the customer to reach an optimal
       operating efficiency for the customer's system as a whole.

     - Technical support. Customers seeking technical support from the group may
       enter into service agreements that best suit their needs. These service
       agreement plans are designed to give customers to ability to receive
       direct support from our teams at pre-determined pricing and service
       levels.

CUSTOMERS

     The server group's largest customers purchase their products through
indirect channels. Typical customers include:

Agriculture Bank -- China
Abbey National Bank
BMW
CVS
Daimler-Chrysler
French Telecom
KFC
Kmart
Lufthansa
Pep Boys
Pizza Hut
Polish Police

     Many of the professional services projects have been with world class
companies such as the Nasdaq, Kmart and Italian Telecom.

SALES, MARKETING AND DISTRIBUTION

     The server group sells to small and medium enterprise purchasers through a
worldwide network of more than 15,000 distributors, resellers, system
integrators and OEMs. The server group sells to replicated site and large
enterprise purchasers through a collaboration between the group's own field
sales and system engineering staff and the corresponding staffs of OEMs, large
value added resellers, or system integrators.

     The sales channel is global. In addition to the North American and Western
European countries, the server group also operates in Eastern Europe, India and
China. The management and support of the channel partners is a key core
competence for the server group. The group makes investments in channel
education, information dissemination and lead generation.

     The server group also sells to OEMs and has a strong working relationship
with a number of the major Intel system builders such as IBM, Compaq,
ICL/Fujitsu, Siemens and Unisys. Each of these OEMs has their own channels of
distribution. The server group has developed programs that allow the OEMs to
work with the server group to mutually support both distribution channels.

     The professional services group sells to customers through a combination of
referral sales from the Server Group and dedicated direct sales effort.

     Server marketing supports the sales activity of both the direct SCO sales
team and the sales forces of our channel partners. Activities include product
introductions, promotions, training and distribution of product information, as
well as direct programs that focus on branding, solutions, advertising,
tradeshows, press releases, and marketing literature. Marketing activities are
often collaborative efforts with OEMs, independent hardware vendors, independent
software vendors, distributors, value added resellers, system integrators,
education centers and support centers.

COMPETITION

     Throughout its long existence the server group has always had many fierce
competitors. These have included AT&T, Novell, SUN Solaris, Interactive systems
and of course Microsoft. Most recently, the two major competitive alternatives
to SCO's UNIX products have been Microsoft NT and Linux. While SCO believes that
the server groups' products retain a competitive advantage in a number of
targeted application areas, both of these competitors are restricting the
overall market available to SCO products, including some markets where SCO has
been successful in the past.

ENGINEERING AND DEVELOPMENT

     The server group has invested and will continue to invest in the
development of new products and new features for existing products. The
development team includes the successors to the original Bell Labs team that
originally developed UNIX over 25 years ago. The development process is modeled
to standard, commercial software engineering practices. These practices are
applied to both documentation and

                                       109
<PAGE>   122

procedures. As result, products can be offered on several operating platforms
without significant additional efforts and with relatively quick adaptation
times for new technologies. While most products and features are developed
in-house, some modules, and base technologies are licensed from third parties
and integrated into the final products.

     The professional services group maintains strict standards of quality and
procedures by employing industry "best practices." The development teams seek to
deliver their services as modules or productized services that are easily
replicated for different customers in different applications.

     As of September 13, 2000, the development team consists primarily of 123
employees, located in Murray Hill, New Jersey and Santa Cruz, California.

INTELLECTUAL PROPERTY

     The success of the server group largely depends on the ability to protect
trademarks, trade secrets, and certain proprietary technology. To accomplish
this, the group relies on a combination of trademark and copyright laws and
trade secrets. Both the server and professional services groups also require
their employees and consultants to sign confidentiality and nondisclosure
agreements.

     SCO also owns the trademark rights to "OPENSERVER" and "UNIXWARE" in the
United States. On or around May 23, 2000, SCO was made aware that X/Open (the
owner of the UNIX trademark) filed a cancellation action against SCO's UnixWare
trademark registration in Japan. On or around May 23, 2000, SCO was made aware
that a joint opposition action had been filed by X/Open (the owner of the UNIX
trademark) and Novell against our European Community Trademark Application.

     Despite efforts to protect trademark rights, unauthorized third parties
have in the past attempted and in the future may attempt to misappropriate these
trademark rights. There is no certainty that the continued misappropriation of
the trademarks can be prevented or enforced. The laws of some foreign countries
do not protect these trademark rights to the same extent as do the laws of the
United States. In addition, policing unauthorized use of these trademark rights
is difficult, expensive and time consuming. The loss of any material trademark
could have a material negative impact on the server and professional services
group business, operating results and financial condition.

     The server and professional services groups do not believe that their
products infringe the rights of other third parties. However, these products are
comprised of many distinct software components, developed by many independent
parties, and therefore third parties in the past asserted, and may in the future
assert infringement claims against us which may result in costly litigation or
require the groups to obtain a license to third party intellectual property
rights. There can be no assurance that such licenses can be obtained on
reasonable terms or at all, which could have a material negative impact on the
server and professional services group business, operating results and financial
condition.

EMPLOYEES

     As of September 13, 2000, the server group had a total of 508 employees and
the Professional Services Group had a total of 38 employees. Of these totals,
123 were in software engineering, 188 in sales and marketing, 104 in customer
service, and 131 in operation, administrative and other positions. From time to
time, the groups also employ independent contractors to complement and support
the groups' efforts. The employees are not represented by any labor union and
are not subject to a collective bargaining agreement, and there has never been
any work stoppage. The server and professional services groups believe that
relations with employees are good.

FACILITIES

     The server and professional services groups are presently headquartered
with SCO in Santa Cruz, California, where SCO leases administrative, sales and
marketing, product development and distribution facilities. SCO leases
additional facilities for administration, sales and marketing and product
development

                                       110
<PAGE>   123

in Murray Hill, New Jersey and Watford, England. The leases for SCO's facilities
expire at various dates through 2020. SCO has renewal options, at fair market
value, under many of these leases and believes that in any event additional or
alternative space adequate to serve the Server and Professional Services Groups'
foreseeable needs would be available on commercially reasonable terms. SCO's
field operations occupy leased facilities in 12 locations in the United States.
In addition, SCO's subsidiaries and sales and representative offices in France,
Germany, Italy, Spain, Sweden, Denmark, Singapore, Australia, China, India,
Canada, Brazil and Mexico lease space for their operations. Worldwide, SCO
leases property in 38 locations consisting of an aggregate of approximately
370,000 square feet. SCO believes that these facilities are adequate for its
needs and the needs of the Server and Professional Services Groups in the
foreseeable future.

LEGAL PROCEEDINGS

     The server and professional services groups are not a party to any material
proceedings.

of substantially all of Caldera's assets, (3) approval of a merger or
consolidation in which at least 50% of the voting securities are acquired, and
(4) certain changes in the composition of the Company's board of directors.
Specific provisions for Senior Vice Presidents and Executive Officers include
but are not limited to the following: salary and bonus payments equal to 150% of
then current annual base salary and insurance benefits for a period up to six
months. Specific provisions for Vice Presidents include but are not limited to
the following: salary and bonus payments equal to 100% of then current annual
base salary and bonuses, 12 months of accelerated vesting on outstanding stock
options and continuation insurance benefits for a period of six months.

EMPLOYMENT AGREEMENTS

     SCO has agreed to encourage the following management employees to enter
into employment agreements with New Caldera:

     David McCrabb;

     Jack Moyer; and

    certain vice presidents and director level employees of the server and
    professional services groups.

Terms of the agreements

     Under the proposed terms of the employment agreements, these management
employees will be paid a base salary consistent with their current base salary.
A bonus plan comparable to their current bonus plan will be put in place. These
employment agreements would provide for a term of 1-2 years. In addition, each
employment agreement would provide that at the end of its term, the employee
would continue on an at-will basis.

Severance provisions

     Generally, if New Caldera were to terminate one of these employment
agreements without cause, the affected employee would be entitled to severance
pay ranging from 75% - 150% of base salary and accelerated vesting ranging from
9 months to 18 months.

     The employee would not be entitled to receive severance benefits if the
employee's employment terminates by reason of employee's voluntary resignation,
if New Caldera terminated the employee's employment after the last day of the
employment term or if the termination were for cause.

Noncompetition provisions

     The employment agreements would also provide that the employees may not
compete with New Caldera for the duration of the severance period, which ranges
from 9 - 18 months after termination of employment.

     Severance payments would cease upon the employee accepting employment or
other position with a direct competitor of New Caldera.

EXECUTIVE COMPENSATION OF NEW CALDERA

     It is anticipated that those employees of SCO who become executive officers
of New Caldera will be compensated generally in accordance with the proposed
terms of the employment agreements described above. For employees of Caldera
that become executive officers of New Caldera, New Caldera will assume the terms
of the senior executive severance agreements and will rely on its compensation
committee to recommend any increase in the form and amount of compensation to be
paid above their current compensation levels at Caldera.

     It is anticipated that when the compensation committee meets to determine
compensation, the committee will generally adhere to compensation policies which
reflect the belief that:

     - New Caldera must attract and retain individuals of outstanding ability
       and motivate and reward them for sustained performance;

     - a portion of an executive's compensation should be at risk based upon
       that executive's and New Caldera's performance; and

     - levels of compensation should generally be in line with that offered by
       comparable corporations.

OPTION GRANTS IN LAST FISCAL YEAR

     The following table presents the grants of stock options under Caldera's
1998 Stock Option Plan during fiscal 1999, ended October 31, 1999, to each of
Caldera's executive officers named in the Summary Compensation Table.

     All option grants under the 1998 Stock Option Plan are nonqualified stock
options. Options expire ten years from the date of grant.

     The exercise price of each option granted is equal to the fair market value
of Caldera's common stock, as determined by Caldera's board on the date of
grant. In fiscal 1999, Caldera granted to its employees options to purchase a
total of 3,106,566 shares of Caldera's common stock.

     Potential realizable values are computed by

     - Multiplying the number of shares of common stock subject to a given
       option by the exercise price per share,

     - Assuming that the aggregate option exercise price derived from that
       calculation compounds at the annual 5% or 10% rates shown in the table
       for the entire 10 year term of the option, and

     - Subtracting from that result the aggregate option exercise price.

     The 5% and 10% assumed annual rates of stock price appreciation are
required by the rules of the Securities and Exchange Commission and do not
represent our estimate or projection of future common stock prices.

1998 STOCK OPTION PLAN

     The 1998 Stock Option Plan was adopted by Caldera's board of directors on
December 29, 1998 and subsequently approved by the stockholders. The plan became
effective upon its adoption by the board and has been amended on various
occasions as Caldera has grown and changed. The 1998 Stock Option Plan was
superseded by the 1999 Omnibus Stock Incentive Plan, and no additional options
may be granted under the 1998 Stock Option Plan (upon the expiration of
previously granted options or otherwise).

     5,000,000 shares of common stock were authorized for issuance under the
1998 Stock Option Plan. Options to purchase 3,252,088 shares of common stock
were granted under the 1998 Stock Option Plan of which 276,433 options have been
exercised or cancelled and 2,975,655 of which remain outstanding.

     Under the 1998 Stock Option Plan, Caldera may grant eligible individuals in
Caldera's employ or service (including officers, non-employee board members and
consultants) non-qualified options to purchase shares of Caldera's common stock.

     The 1998 Stock Option Plan is administered by Caldera's compensation
committee. The compensation committee determines which eligible individuals are
to receive options under the 1999 Stock Option Plan, the time or times when each
option is to be granted, the number of shares subject to each option, the
exercise price of each option and the vesting schedule and the other terms to be
in effect for each option. The exercise price for the options granted under the
1998 Stock Option Plan may be less than the fair market value of a share of
common stock on the date of grant, payment is immediately due and payable upon
exercise of an option and must be paid in cash or with a check made payable to
Caldera.

     In the event that Caldera is acquired, whether by merger or asset sale,
each outstanding option granted under the 1998 Stock Option Plan that has vested
may, at Caldera's discretion, be cashed out, be converted to options of the
acquiring entity, be assumed by the acquiring entity, or otherwise disposed of
in the manner provided in any shareholder-approved agreement or plan governing
such transaction. In addition, in the absence of any governing provisions in any
shareholder-approved agreement or plan

                                       118
<PAGE>   131

governing such transaction, Caldera may, on a case-by-case basis, require any
vested, exercisable options to be cashed out and terminated in exchange for a
lump sum cash payment, shares of the acquiring entity or a combination thereof
equal in value to the fair market value of the option.

     In the event Caldera is acquired, whether by merger or asset sale, each
outstanding option granted under the 1998 Stock Option Plan that has not vested
shall terminate as of the effective date of such transaction, unless otherwise
provided in the shareholder-approved agreement or plan governing such
transaction or by the compensation committee in its sole discretion on a
case-by-case basis.

     If options are assumed by the purchasing or successor corporation, each
option assumed will be adjusted to apply to the number and class of securities
which would have been issuable to the option holder had the option been
exercised immediately prior to the merger or asset sale. Following such merger
or asset sale, appropriate adjustments will also be made to the number and class
of securities available for issuance under the 1998 Stock Option Plan and the
exercise price payable per share under each outstanding option, provided the
aggregate exercise price payable for such securities shall remain the same.

     The board may amend or modify the 1998 Stock Option Plan at any time,
subject to any stockholder approval required by governing laws and exchange
regulations. The 1998 Stock Option Plan will terminate no later than December
29, 2008.

1999 OMNIBUS STOCK INCENTIVE PLAN

     The 1999 Omnibus Stock Incentive Plan (the "1999 Plan") is intended to
serve as the successor equity incentive program to Caldera's 1998 Stock Option
Plan. The 1999 Plan became effective upon its adoption by the board of directors
and shareholders on December 1, 1999. It was amended by the board on March 10,
2000 to increase by 500,000 the number of shares authorized for issuance under
the 1999 Plan.

     This amendment was approved by the stockholders of Caldera in March 2000.
It was again amended by the board of directors on July 14, 2000 in order to make
the following changes:

     - to permit the grant of non-qualified options with an exercise price below
       fair market value,

     - to permit the exercise of non-qualified options up to 120 days after
       termination of service,

     - to permit exercise of an option up to 30 days after termination of
       service for cause,

     - in connection with a sale, change of control or liquidation of Caldera,
       to permit Caldera or the acquiring entity to cash out, convert to options
       of the acquiring entity, or assume any vested options granted under the
       1999 Plan,

     - in connection with a sale, change of control or liquidation of Caldera,
       to provide that non-vested options shall terminate unless otherwise
       provided in the governing agreements or determined by the committee, and

     - to permit Caldera to grant shares of restricted stock and phantom stock
       that vest without regard to the satisfaction of pre-established
       performance goals.

     This amendment was approved by the board on July 14, 2000 and became
effective at the time of such approval.

     In addition, the board has approved amendments that will effect the
following changes: (i) increase the maximum number of shares of common stock
authorized for issuance over the term of the 1999 Plan by an additional
2,300,000 shares to 6,405,238 shares, (ii) establish an automatic share increase
feature pursuant to which the number of shares available for issuance under the
1999 Plan will automatically increase, beginning with the 2000 calendar year, as
of November 1 of each year, by 3% of the total number of shares of common stock
outstanding on the previous October 31st, (iii) add a formula awards program
pursuant to which directors of Caldera will automatically be granted options to
purchase shares of common stock at specified times, including an option to
purchase 100,000 shares of common stock on the
                                       119
<PAGE>   132

date of the annual shareholders meeting during each even numbered calendar year.
These amendments are the subject of Proposal Two. Please see page 143.

     The 1999 Plan presently authorizes the grant of incentive awards with
respect to 4,105,238 shares of common stock (subject to increase if the
amendments included in Proposal Two are approved by the stockholders). The 1999
Plan allows for the grant of awards in the form of incentive and non-qualified
stock options, stock appreciation rights, restricted shares, phantom stock and
stock bonuses.

     Persons eligible to receive awards under the 1999 Plan include all
employees and directors of Caldera and its subsidiaries and such other persons
whom the committee determines are expected to make a contribution to Caldera. No
one participant in the 1999 Plan may receive option grants or any other awards
for more than 200,000 shares in the aggregate in any tax year of Caldera
Systems, except for grants of options for a total of 379,752 shares to Mr. Love
authorized by our board of directors in December 1999 and January 2000.

     The 1999 Plan is administered by Caldera's compensation committee. The
compensation committee determines which eligible individuals are to receive
awards under the 1999 Plan, the type of award to be made, the time or times when
such awards are to be made, the number of shares subject to each such award, and
the vesting schedule and the other terms to be in effect for the award.

     The exercise price for the options may be paid in cash, in shares of
Caldera's common stock valued at fair market value on the exercise date or by
having Caldera retain sufficient shares of its common stock from shares which
would be issuable upon the exercise of the option. The option may also be
exercised through a same-day sale program without any cash outlay by the
optionee.

     The 1999 Plan also permits grant of the following:

     - tandem stock appreciation rights, which provide the holders with the
       election to surrender his or her options for a cash appreciation
       distribution from Caldera equal to the fair market value of the vested
       shares subject to the surrendered option less the aggregate exercise
       price payable for such shares;

     - stand-alone stock appreciation rights, which entitle the holder to
       receive a cash payment from Caldera equal to the fair market value of the
       vested shares subject to the right less the base price for such right;

     - phantom stock awards, which entitle the holder to receive in cash the
       fair market value of a specified number of shares of our common stock on
       the vesting date,

     - restricted stock awards, which involves the grant of shares of common
       stock that are subject to restrictions on transferability during a
       vesting period and are forfeited if certain conditions are not met, and

     - stock bonus awards, which involve outright grant of shares of common
       stock without condition.

     In the event that Caldera is acquired (whether by merger, liquidation or
asset sale) or there is a change in who controls Caldera (effected through an
acquisition of 50% or more of Caldera's voting stock or by specified change in
the composition of Caldera's board), the incentive awards granted under the 1999
Plan are treated as follows:

     - each option and stock appreciation right that has vested may, at
       Caldera's discretion, be cashed out, be converted to options of the
       acquiring entity, be assumed by the acquiring entity, or otherwise
       disposed of in the manner provided in any shareholder-approved agreement
       or plan governing such transaction. In addition, in the absence of any
       governing provisions in any shareholder-approved agreement or plan
       governing such transaction, Caldera may, on a case-by-case basis, require
       any vested, exercisable options to be cashed out and terminated in
       exchange for a lump sum cash payment, shares of the acquiring entity or a
       combination thereof equal in value to the fair market value of the
       option.

                                       120
<PAGE>   133

     - each outstanding option and stock appreciation right granted under the
       1999 Plan that has not vested shall terminate as of the effective date of
       such transaction, unless otherwise provided in the shareholder-approved
       agreement or plan governing such transaction or by the compensation
       committee in its sole discretion on a case-by-case basis.

     - each outstanding phantom stock award that has not vested prior to the
       date of a change of control shall immediately expire,

     - all restrictions on vested shares of restricted stock shall immediately
       lapse, and all unvested shares of restricted stock shall immediately be
       canceled, and

     - each outstanding stock bonus shall not be affected.

     The board may amend or modify the 1999 Plan at any time, subject to
stockholder approval if required by governing exchange regulations or if
necessary to satisfy applicable provisions of governing tax laws.

2000 EMPLOYEE STOCK PURCHASE PLAN

     The 2000 Employee Stock Purchase Plan was adopted by Caldera's board of
directors on February 15, 2000 and was approved by its stockholders on March 1,
2000. The plan became effective on March 20, 2000. The plan is designed to allow
eligible employees of Caldera Systems, Inc. and its participating subsidiaries
to purchase shares of its common stock, at semi-annual intervals, through their
periodic payroll deductions. A total of 500,000 shares of Caldera's common stock
has been reserved for issuance under the plan. In connection with the
combination, the board has approved an increase by 1.5 million in the number of
shares authorized for issuance under the plan. This increase is being submitted
to the stockholders for approval pursuant to Proposal Three. Please see page
157. The share reserve will increase on the first trading day of each calendar
year beginning with the 2001 calendar year by 1% of the total number of shares
of common stock outstanding on the last day of the immediately preceding year
but no such annual increase will exceed 750,000 shares. In no event, however,
may a participant purchase more than 750 shares, nor may all participants in the
aggregate purchase more than 125,000 shares on any one semi-annual purchase
date.

     The plan will have a series of successive offering periods, each with a
maximum duration of 24 months. However, the initial offering period began on
March 20, 2000 and will end on the last business day in April 2002. The next
offering period will begin on the first business day in May 1, 2002, and
subsequent offering periods will be set by Caldera's compensation committee.
Shares will be purchased on semi-annual purchase dates (the last business day of
April and October each year) during the offering period. The first purchase date
will be October 31, 2000. Should the fair market value of Caldera's common stock
on any semi-annual purchase date be less than the fair market value on the first
day of the offering period, then the current offering period will automatically
end and a new offering period will begin, based on the lower fair market value.

     Individuals who are eligible employees on the start date of any offering
period may enter the plan on that start date or on any subsequent semi-annual
entry date (generally May 1 or November 1 each year). Individuals who become
eligible employees after the start date of the offering period may join the plan
on any subsequent semi-annual entry date within that period.

payroll deductions and the accumulated payroll deductions will be applied to the
purchase of shares on the participant's behalf on each semi-annual purchase date
(the last business day in April and October each year). The purchase price per
share will be 85% of the lower of the fair market value of our common stock on
the participant's entry date into the offering period or the fair market value
on the semi-annual purchase date.

     The board may at any time amend or modify the plan.  The plan will
terminate no later than the last business day in April 2010.

                CERTAIN TRANSACTIONS OF CALDERA AND NEW CALDERA

     Other than the transactions described below, since October 31, 1997 there
has not been, nor is there currently proposed, any transaction or series of
similar transactions to which Caldera was or will be a party:

     - in which the amount exceeds $60,000; and

     - in which any director, executive officer, holder of more than 5% of our
       common stock or any member of their immediate family had or will have a
       direct or indirect material interest.

RELATIONSHIP WITH CALDERA, INC., A UTAH CORPORATION

     Caldera began operations in 1994 as a business unit comprising
substantially all of the operations of Caldera, Inc., a Utah Corporation. In
July 1996, through an asset purchase, Caldera, Inc. acquired an additional
business unit which was not engaged in developing and marketing Linux software.
Caldera, Inc. subsequently made the strategic determination to separate its two
business lines into separate entities. Therefore, pursuant to an Asset Purchase
and Sale Agreement dated as of September 1, 1998, as amended, by and between
Caldera, Inc. and Caldera Systems, Inc., Caldera, Inc. sold to Caldera Systems
certain assets of its Linux software business unit for $19.9 million, $15.0
million of which was paid in the form of a cash payment in fiscal year 1999,
$36,174 of which was in the form of assumption of liabilities and $4.9 million
of which was in the form of forgiveness of a note receivable from Caldera, Inc.
Caldera, Inc. was dissolved in January 2000.

     On September 1, 1998, we entered into a sublease with Caldera, Inc. for
office space in Orem, Utah. The sublease provided for annual rent of
approximately $150,000 and was terminated pursuant to its terms on August 31,
2000.

     Ralph J. Yarro III, chairman of Caldera's board of directors, and Raymond
J. Noorda, one of Caldera's directors, were directors of Caldera, Inc. Prior to
its dissolution in January 2000, Caldera, Inc. was majority-owned by The Canopy
Group, Inc. which holds more than 5% of our common stock. The Noorda Family
Trust, of which Mr. Noorda and his spouse are co-trustees, is the controlling
stockholder of The Canopy Group, Inc.

RELATIONSHIP WITH THE CANOPY GROUP, INC.

     Effective August 31, 1998, Caldera sold 16,000,000 shares of its common
stock to The Canopy Group, Inc. for an aggregate purchase price of $21.0
million. Of this amount, $16.0 million was paid in cash ($519,000 in fiscal year
1998 and $15.5 million -- non-interest bearing -- in fiscal year 1999), and $4.9
million was in the form of a note receivable from Caldera, Inc., which The
Canopy Group transferred to us.

     Effective September 1, 1998, Caldera entered into a convertible promissory
note with The Canopy Group. The note, which was secured by all of Caldera's
assets, was due on December 31, 1999. The note accrued interest at the prime
rate, less  1/2%, and was convertible into our common stock at $1.00 per share.
A total of $4.8 million was advanced under the note. The principal balance,
along with approximately $455,000 of accrued interest was converted into
5,273,974 shares of our common stock on August 19, 1999.

     Under a secured promissory note dated as of December 29, 1999, Caldera
borrowed $300,000 from The Canopy Group. The note bears interest of 9.5% per
annum and was payable upon demand or on January 14, 2000. Caldera paid the note
in full on January 5, 2000.

     The Canopy Group holds more than 5% of Caldera's common stock. Mr. Noorda,
one of Caldera's directors, and his spouse are co-trustees of the Noorda Family
Trust, which is the controlling stockholder of The Canopy Group.

                                       122

     Until June 2000, Caldera utilized a 401(k) plan sponsored by The Canopy
Group for its employees, under which it made matching contributions from January
1, 2000 through June 2000. In June 2000, Caldera adopted its own 401(k) plan.

     The Canopy Group, formerly NFT Ventures, is a venture capital company that
invests primarily in start-up high technology companies that encourage the
adoption, deployment and promotion of Linux. The Canopy Group currently holds
equity interests in companies in the fields of data storage and protection,
Linux operating systems, data satellites, clustering, universal voice messaging,
Java and eCommerce.

     As a result of an option agreement between The Canopy Group and Ralph J.
Yarro III, which was subsequently rescinded, Caldera expensed a one-time
compensation charge of approximately $372,000 during the quarter ended April 30,
2000. The option agreement allowed Mr. Yarro to purchase shares of Caldera's
common stock directly from The Canopy Group. No shares were purchased under the
agreement. Mr. Yarro is the president and chief executive officer of The Canopy
Group and the Chairman of Caldera's board of directors.

RELATIONSHIP WITH MTI TECHNOLOGY CORPORATION

     Effective July 27, 1999, Caldera sold 5,333,333 shares of its common stock
to MTI Technology Corporation for an aggregate purchase price of $6.0 million.
Of this amount, $3.0 million was paid at closing, $1.5 million was due at
January 1, 2000, and $1.5 million was due in July 2000. The $1.5 million due at
January 1, 2000, was paid on November 15, 1999 in return for a waiver by Caldera
of accrued and future interest on the unpaid portions of the purchase price.
Caldera believes that the waiver of interest in consideration for the
acceleration of payment was not more favorable to MTI than the terms Caldera
would have been able to negotiate with an unrelated party. The remaining $1.5
million was paid in full in August 2000.

     On August 12, 1999, Caldera entered into a Distribution and License
Agreement with MTI Technology Corporation. Under this agreement, MTI Technology
Corporation includes as available for sale in its price book all of Caldera's
products, technology or services that are commercially available for sale, and
Caldera sells or licenses, as applicable, to MTI Technology Corporation, and
allow MTI Technology Corporation to sell, re-sell, license, reproduce, use,
distribute, sublicense, have made and prepare derivative works of all of
Caldera's products, technology, or services that are commercially available.
This agreement is terminable by either party on 90 days prior written notice.

     Caldera uses a computer system provided by MTI Technology Corporation
without charge. The computer system is valued at $105,000.

     MTI Technology Corporation owns more than 5% of Caldera's common stock. The
Canopy Group, Inc. holds more than 45% of the outstanding common stock of MTI
Technology Corporation. The Noorda Family Trust, of which Mr. Noorda and his
spouse are co-trustees, is the controlling stockholder of The Canopy Group. Mr.
Noorda is one of Caldera's directors and is chairman of the board of directors
of MTI Technology Corporation. Thomas P. Raimondi, Jr., one of our directors, is
president and chief executive officer of MTI Technology Corporation.

RELATIONSHIP WITH LINEO, INC.

     In January 2000, we exchanged with Lineo, Inc. 1,250,000 shares of our
common stock in return for 3,238,437 shares of common stock of Lineo. On May 11,
2000, The Canopy Group transferred 1,761,563 additional shares of Lineo's common
stock held by The Canopy Group to us in the form of a capital contribution.

     On August 31, 2000, Caldera and Metrowerks Holdings, Inc., an affiliate of
Motorola, Inc., entered into a Stock Purchase and Sale Agreement whereby Caldera
and The Canopy Group are to sell 2.0 million and 1.0 million shares of common
stock of Lineo, Inc, respectively, to Metrowerks Holdings at $7.50 per

                                       123
<PAGE>   136

share. The sale will close upon the receipt of certain required regulatory
approvals and the completion of other closing conditions.

     In conjunction with the sale of the common stock of the common stock of
Lineo, Caldera also entered into a stockholder agreement among The Canopy Group,
Lineo Inc. and certain other stockholders of Lineo, which provide for right of
first refusal for the benefit of Metrowerks Holdings with request to Lineo
shares held by Caldera and the other Lineo stockholders party to the agreement.
Caldera has also agreed to indemnify Metrowerks Holdings up to an amount equal
to the amount of proceeds received by Caldera for any damage sustained by
Metrowerks Holdings as a result of breaches by Caldera under the stock purchase
and sale agreement and the stockholder agreement or for breaches by Lineo under
a warrant agreement between Lineo and Metrowerks Holdings.

     Lineo distributes copies of our OpenLinux products to certain of its
customers. Caldera has accounts receivable from Lineo in an aggregate amount of
approximately $16,700 as of July 31, 2000. Lineo is majority-owned by The Canopy
Group, Inc. The Noorda Family Trust, of which Mr. Noorda and his spouse are
co-trustees, is the controlling stockholder of The Canopy Group, Inc. Mr.
Noorda, John R. Egan and Ralph T. Yarro III, each of whom is one of Caldera's
directors, are directors of Lineo, Inc.

RELATIONSHIP WITH THE SANTA CRUZ OPERATION

     On February 28, 2000, Caldera entered into an agreement for Lineo
professional services with SCO, pursuant to which SCO is to provide customer
support and other related services to customers of Caldera from time to time for
specified fees. This agreement is currently being performed by SCO's
professional services group, and will be extinguished upon the closing of the
combination, at which time New Caldera would become the owner of the
professional services group.

     On June 27, 2000, Caldera and SCO entered into an OEM Distribution
Agreement. Under the terms of the agreement, Caldera is granted a non-exclusive,
non-transferable, worldwide license certain of SCO's products, including
enhancements and improvements, for distribution and sale to end users and
specified resellers. Caldera pays current list price, less 42% for all SCO
products under the Agreement. The term of the agreement is for one year with
automatic renewals for additional one year periods unless the agreement is
terminated.

     On February 1, 2000, Caldera and SCO entered into a Strategic Business
Agreement. The Agreement provides for a number of joint marketing activities
between the parties, including, but not limited to, the following: (i)
participation together in industry shows, (ii) cross recruit and cross match
channel partners for SCO's Tarantella product line and Caldera's OpenLinux
e-Server, (iii) cross-reference each others websites and product solutions and
(iv) discussion of Caldera's channel initiatives. Additionally, Caldera agreed
to provide ten copies of OpenLinux to SCO for its internal use and SCO agrees to
provide three copies of SCO's Tarantella Express product. Caldera and SCO also
agreed to cooperate and work together to port Tarantella Express products to
Caldera's OpenLinux, eServer and eDesktop. The term of the agreement is for one
year with automatic renewals for additional one year periods unless the
agreement is terminated.

              DESCRIPTION OF CALDERA AND NEW CALDERA CAPITAL STOCK

GENERAL

     The following summary includes all of the material provisions of Caldera
and New Caldera's capital stock. Except where otherwise indicated, they are
identical. However, you should read the New Caldera certificate of incorporation
attached as Appendix D and the New Caldera bylaws attached as Appendix E.

     The authorized capital stock of Caldera consists of 100,000,000 shares, of
which 75,000,000 are common stock, par value $0.001 per share, and 25,000,000
are preferred stock, par value $0.001 per share. If proposal four included in
this Proxy Statement is approved by the stockholders, the authorized capital
stock of Caldera and New Caldera will consist of 200,000,000 shares, of which
175,000,000 will be common stock, par value $0.001 per share, and 25,000,000
will be preferred stock, par value $0.001 per share. Based on the shares of
Caldera common stock outstanding on September 1, 2000, immediately following the
combination, there will be outstanding approximately 55,419,110 shares of New
Caldera common stock.

COMMON STOCK

     Dividend Rights.  Subject to preferences that may apply to shares of
preferred stock outstanding at the time, the holders of outstanding shares of
common stock are entitled to receive dividends out of assets legally available
at the times and in the amounts as the board of New Caldera may from time to
time determine.

     Voting Rights.  Each common stockholder is entitled to one vote for each
share of common stock held on all matters submitted to a vote of stockholders.
Cumulative voting for the election of directors are not provided for in New
Caldera's articles of incorporation, which means that the holders of a majority
of the shares voted will be able to elect all of the directors then standing for
election.

     No Preemptive or Similar Rights.  New Caldera's common stock is not
entitled to preemptive rights and is not subject to conversion or redemption.

     Right to Receive Liquidation Distributions.  Upon a liquidation,
dissolution, or winding up of New Caldera, the assets legally available for
distribution to New Caldera's stockholders are distributable ratably among the
holders of New Caldera's common stock and any participating preferred stock
outstanding at that time after payment of liquidation preferences, if any, on
any outstanding preferred stock and payment of other claims of creditors.

PREFERRED STOCK

     Upon the closing of the combination, there will be no shares of preferred
stock outstanding. The board of directors of New Caldera will be authorized,
without further stockholder approval, to issue from time to time up to an
aggregate of 25,000,000 shares of preferred stock in one or more series and to
fix or alter the designations, preferences, rights and any qualifications,
limitations or restrictions of the shares of each series thereof, including the
dividend rights, dividend rates, conversion rights, voting rights, terms of
redemption, including sinking fund provisions, redemption price or prices,
liquidation preferences and the number of shares constituting any series or
designation of series. See "-- Anti-Takeover Effects of Various Provisions of
Delaware Law and New Caldera's Certificate of Incorporation and Bylaws."

REGISTRATION RIGHTS

     Pursuant to a second amended and restated investors rights agreement, dated
January 7, 2000, which Caldera Systems entered into with holders of 11,596,146
shares of its common stock (assuming conversion of all outstanding shares of
preferred stock), the holders of these shares will be entitled to certain
registration rights regarding the same number of shares of New Caldera to be
owned by them upon the closing of the combination. The registration rights
provide that if New Caldera proposes to register any

                                       132
<PAGE>   145

securities under the Securities Act, either for its own account or for the
account of other security holders exercising registration rights, they are
entitled to notice of the registration and are entitled to include shares of
their common stock in the registration. This right is subject to conditions and
limitations, including the right of the underwriters in an offering to limit the
number of shares included in the registration. Beginning on September 20, 2000,
the holders of at least 22 percent of these shares may also require New Caldera
to file up to two registration statements under the Securities Act at its
expense with respect to their shares of common stock. New Caldera is required to
use its best efforts to effect these registrations, subject to conditions and
limitations. Furthermore, the holders of these shares may require New Caldera to
file additional registration statements on Form S-3, subject to conditions and
limitations. These rights terminate on the earlier of March 20, 2003, or when a
holder is able to sell all its shares pursuant to Rule 144 under the Securities
Act in any 90-day period.

     Pursuant to the reorganization agreement, New Caldera has agreed to
register shares of New Caldera held by SCO for distribution to SCO's
shareholders. See "               ".

DELAWARE ANTI-TAKEOVER LAW AND CHARTER PROVISIONS

     The provisions of the Delaware General Corporation Law, New Caldera's
certificate of incorporation and its bylaws described below may have the effect
of delaying, deferring, or discouraging another person from acquiring control of
New Caldera.

     New Caldera is subject to the provisions of Section 203 of the Delaware
General Corporation Law regulating corporate takeovers. This section prevents
Delaware corporations from engaging, under limited circumstances, in a business
combination, which includes a merger or sale of more than 10% of the
corporation's assets, with any interested stockholder, which is a stockholder
who owns 15% or more of the corporation's outstanding voting stock, as well as
affiliates and associates of stockholders, for three years following the date
that the stockholder became an interested stockholder unless:

     - the transaction is approved by the board of directors before the date the
       interested stockholder attained that status;

     - upon the closing of the transaction that resulted in the stockholder
       becoming an interested stockholder, the stockholder owned at least 85% of
       the voting stock of the corporation outstanding at the time the
       transaction commenced; or

     - on or after the date the business combination is approved by the board of
       directors and authorized at an annual or special meeting of stockholders
       by at least two-thirds of the outstanding voting stock that is not owned
       by the interested stockholder.

     A Delaware corporation may opt out of this provision with an express
provision in its original certificate of incorporation or an express provision
in its certificate of incorporation or bylaws resulting from a stockholders'
amendment approved by at least a majority of the outstanding voting shares.
However, New Caldera has not opted out of this provision. This provision of the
Delaware General Corporation Law could prohibit or delay mergers or other
takeover or change-in-control attempts and may discourage attempts to acquire
New Caldera.

CHARTER AND BYLAWS

Charter

     New Caldera's certificate of incorporation provides that all stockholder
actions must be effected at a duly-called annual or special meeting and not by a
consent in writing. New Caldera's certificate of incorporation also requires the
approval of its board of directors to adopt, amend or repeal its bylaws. In
addition, New Caldera's certificate of incorporation permits the stockholders to
adopt, amend or repeal its bylaws only upon the affirmative vote of the holders
of at least two-thirds of the voting power of all then outstanding shares of
stock entitled to vote.

                                       133
<PAGE>   146

     Directors are removable for cause only by stockholders holding a majority
of the then-outstanding shares of stock entitled to vote. Vacancies on the board
of directors resulting from death, resignation, removal or other reason may be
filled by a majority of the directors then in office, even if less than a
quorum. Vacancies from newly created directorships must be filled by a majority
of the directors then in office. Lastly, the provisions in the certificate of
incorporation described above and other provisions pertaining to the limitation
of liability and indemnification of directors may be amended or repealed only
with the affirmative vote of the holders of at least two-thirds of the voting
power of all then outstanding shares of stock entitled to vote.

     These provisions may have the effect of deterring hostile takeovers or
delaying changes in the control or management of New Caldera, which could have
an adverse effect on the market price of its common stock.

Bylaws

     New Caldera's bylaws also contain many of the provisions in its certificate
of incorporation described above. Its bylaws will not permit stockholders to
call a special meeting. In addition, New Caldera's bylaws establish an advance
notice procedure for matters to be brought before an annual or special meeting
of its stockholders, including the election of directors. Business permitted to
be conducted at any annual meeting or special meeting of stockholders is limited
to business properly brought before the meeting.

     New Caldera's bylaws also provide that it will indemnify officers and
directors against losses that they may incur in investigations and legal
proceedings resulting from their services to New Caldera, which may include
services in connection with takeover defense measures. These provisions may have
the effect of preventing changes in New Caldera's management.

INDEMNIFICATION OF DIRECTORS AND EXECUTIVE OFFICERS AND LIMITATION OF LIABILITY

     New Caldera's certificate of incorporation limits the liability of
directors to the fullest extent permitted by the Delaware General Corporation
Law. In addition, New Caldera's certificate of incorporation and bylaws provide
that it will indemnify its directors and officers to the fullest extent
permitted by the Delaware General Corporation Law. New Caldera will enter into
separate indemnification agreements with its directors and executive officers
that provide them indemnification protection if its certificate of incorporation
is subsequently amended.

TRANSFER AGENT AND REGISTRAR

     The transfer agent and registrar for New Caldera's common stock will be
American Securities Transfer and Trust, Inc.

              COMPARISON OF RIGHTS OF HOLDERS OF SCO COMMON STOCK
                          AND NEW CALDERA COMMON STOCK

     The following is a summary of certain differences between the rights of
holders of SCO common stock and holders of New Caldera common stock. While we
believe that this summary covers the material differences, it may not contain
all of the information that is important to holders of SCO common stock. In
order to more completely understand the differences between the rights of
holders of SCO common stock and holders of New Caldera common stock, SCO
shareholders should carefully read all of the original documents and statutes
referenced in this summary.

     The rights of holders of SCO common stock with respect to such stock are
governed by the articles of incorporation and bylaws of SCO, each as currently
in effect, and the Corporation Law of the State of California. The shares of New
Caldera common stock that will be acquired by SCO and the options to purchase
shares of New Caldera common stock that will be acquired by certain SCO option
holders as a result of the combination will have rights that are governed by the
certificate of incorporation and bylaws of New Caldera, each as in effect as of
the effective time of the combination, and the General Corporation Law of the
State of Delaware.

APPLICABLE STATE CORPORATE LAW

     SCO is incorporated under the laws of the State of California and is
governed by the Corporation Law of the State of California. New Caldera is
incorporated under the laws of the State of Delaware and is governed by the
General Corporation Law of the State of Delaware. As a result of this difference
in governing law, the shares of New Caldera common stock that will be acquired
by SCO and the options to purchase shares of New Caldera common stock that will
be acquired by SCO option holders as a result of the combination may have
statutory rights different than those associated with shares of SCO common
stock.

     Important differences between the Corporation Law of the State of
California and the General Corporation Law of the State of Delaware include, but
are not limited to, the following:

     - Delaware law allows a corporation to limit directors' liability and
       indemnify directors against claims to a greater extent than is permitted
       under California law.

     - Delaware law allows a corporation to take more extensive anti-takeover
       measures than are permitted under California law, including allowing a
       Delaware corporation to eliminate special stockholder meetings and to
       elect a classified board of directors.

     - Delaware law includes a specific anti-takeover statute that prevents
       certain business combinations not approved by the incumbent board.
       California law has no analogous statute.

     In addition, Delaware law and California law differ in their treatment of
appraisal rights, the payment of dividends, and shareholder voting related to
business combinations and combinations.

     As a Delaware corporation, New Caldera is subject to the provisions of
Section 203 of the General Corporation Law of the State of Delaware. Under
certain circumstances, the provisions of Section 203 may make the consummation
of various business transactions by "interested stockholders," as defined in
Section 203, with New Caldera more difficult for a three-year period following
the time that a stockholder becomes an "interested stockholder." A corporation
may waive the protective provisions of Section 203 in its certificate of
incorporation or bylaws, but New Caldera has not currently done so.

CERTIFICATES OF INCORPORATION AND BYLAWS

Authorized and Outstanding Capital Stock

     SCO has two classes of authorized capital stock, designated "common stock"
and "preferred stock." SCO is authorized to issue 100,000,000 shares of common
stock and, as of August 15, 2000, there were 36,121,982 shares of common stock
outstanding. SCO is authorized to issue 20,000,000 shares of preferred

                                       135
<PAGE>   148

stock, with such rights, preferences and designations that the board of
directors of SCO may determine. Currently there are no outstanding shares of SCO
preferred stock.

     New Caldera will have two classes of authorized capital stock, designated
"common stock" and "preferred stock," each with a par value of $0.001 per share.
If proposal four described in this proxy is approved, New Caldera will be
authorized to issue 175,000,000 shares of common stock. New Caldera will be
authorized to issue 25,000,000 shares of preferred stock, with such rights,
preferences and designations that the board of directors of New Caldera may
determine. There are currently no outstanding shares of New Caldera preferred
stock.

Voting Rights

     Except with respect to the election of directors, holders of SCO common
stock are entitled to one vote on all matters submitted to SCO shareholders for
their approval for each share of common stock held. Under certain circumstances,
holders of SCO common stock are entitled to cumulate votes for the election of
directors. Where votes are cumulated for the election of directors, each holder
of SCO common stock is entitled to that number of votes which is equal to the
total number of shares of SCO common stock held, multiplied by the number of
directors being elected. The cumulative number of votes allotted to each SCO
shareholder using this formula may be allocated by such shareholder in any
manner, including for a single director, or for two or more directors, at the
discretion of such SCO shareholder. Under SCO's bylaws, all matters submitted to
the shareholders (including the election of directors) must be approved by a
majority of the votes cast in a meeting where a quorum is present.

     Holders of New Caldera common stock are also entitled to one vote on all
matters submitted to New Caldera stockholders for their approval for each share
held. However, holders of New Caldera common stock are not entitled to cumulate
votes for the election of directors. Pursuant to New Caldera's bylaws, all
matters submitted to the stockholders (including the election of directors) must
be approved by a majority of the votes cast in a meeting where a quorum is
present.

BOARD OF DIRECTORS

  Board Size

     The bylaws of SCO currently provide that the board of directors of SCO may
consist of between seven and twelve directors, and the exact number of directors
has been fixed at nine by resolution of SCO's board. Pursuant to SCO's bylaws,
the permissible range of size of SCO's board of directors may only be changed by
an amendment to the bylaws approved by the shareholders, but the board may
unilaterally fix the size of the board at any level within the permissible
range. SCO's articles of incorporation do not place any restrictions on the size
of SCO's board of directors.

     Pursuant to New Caldera's certificate of incorporation, New Caldera's board
of directors may consist of between five and fifteen directors, as designated in
the bylaws. Within the range permitted by the certificate of incorporation, the
size of New Caldera's board of directors may be changed by resolution of the
board. Pursuant to the reorganization agreement and the stockholders agreement,
the size of the New Caldera board will be fixed at 9.

  Board Classification

     Neither the board of directors of SCO nor the board of directors of New
Caldera is classified.

  Board Vacancies

     SCO's bylaws provide that any vacancy on SCO's board of directors may be
filled by the remaining members of the board of directors (even if less than a
quorum), or the sole remaining director, except that any vacancies created by
removal of a director by vote of the shareholders or court order may only be
filled by a vote of the shareholders. In addition, the shareholders may fill any
vacancies not filled by the

                                       136
<PAGE>   149

directors. SCO's bylaws provide that a vacancy in the board of directors can
result from the death, resignation or removal of a director, a further increase
in the size of the board of directors, or a failure of the shareholders to elect
enough directors to fill the board.

     New Caldera's certificate of incorporation provides that any vacancy on New
Caldera's board of directors, whether from the death, resignation or removal of
a director or an increase in the size of the board of directors, may be filled
in a meeting where a quorum exists by a majority of the directors then in
office, even if less than a quorum, or the sole remaining directors.

  Removal of Directors

     SCO's articles of incorporation and bylaws make no special provisions for
the removal of directors. Under the Corporation Law of the State of California,
any member of SCO's board of directors, or the entire board of directors, may be
removed with or without cause by the holders of a majority of the outstanding
shares of SCO capital stock entitled to vote generally for the election of
directors. Notwithstanding the foregoing, if less than the entire board of
directors is removed, no director may be removed if the votes cast against his
or her removal would be sufficient to elect such director if voted cumulatively.

     The removal of New Caldera's directors is governed by the General
Corporation Law of the State of Delaware, which provides that any member of
SCO's board of directors, or the entire board of directors, may be removed with
or without cause by the holders of a majority of the outstanding shares of SCO
capital stock entitled to vote generally for the election of directors.

Shareholder/Stockholder Action by Written Consent

     Pursuant to SCO's bylaws, shareholders may take formal action at a meeting
of shareholders duly called and held in accordance with the bylaws and
applicable law or pursuant to a written consent. Where shareholders take action
by written consent, such written consent is effective only if signed by
shareholders holding at least the number of shares of capital stock that would
be required to authorize or take such action at a meeting of shareholders at
which all shares of capital stock entitled to vote on such action were present
and voted, except that in the case of election of directors, a written consent
is effective only if signed by the holders of all outstanding shares entitled to
vote for the election of directors.

     Pursuant to New Caldera's bylaws, stockholders may only take formal action
at a duly called stockholder meeting held in accordance with the bylaws and
applicable law. New Caldera's bylaws do not permit stockholders to take action
by written consent.

Ability to Call Special Meetings

     Pursuant to SCO's bylaws, a special meeting of SCO shareholders may be
called by the board of directors of SCO, the chairman of the board of directors,
SCO's president, or the holders of at least 10% of the outstanding shares of SCO
capital stock entitled to vote at the meeting. If any person or group of persons
other than the board of directors, chairman, or president desires to call a
special meeting of SCO shareholders, the person or group must give the chairman,
president, vice-president, or secretary of SCO a written notice stating the
general nature of the business proposed to be transacted. Such written notice
must be delivered not less than 35 nor more than 60 days before the date of the
proposed special meeting. SCO's bylaws provide that no business other than that
specified in the notice may be transacted at a special meeting.

     Pursuant to New Caldera's bylaws, a special meeting of New Caldera
stockholders may be called only by the chairman of the board or by a majority of
the board. The bylaws of New Caldera further provide that the only business that
may be conducted at a special meeting of New Caldera stockholders is such
business as is set forth in the notice of the special meeting.

Advance Notice Provisions for Shareholder/Stockholder Nominations and Proposals

     SCO's bylaws impose no additional notice requirements for shareholder
nominations and proposals beyond those generally necessary for annual and
special meetings.

     New Caldera's bylaws provide that stockholder proposals (and nominations of
directors) will not be considered at any annual meeting of New Caldera
stockholders unless timely made. Stockholder proposals (and nominations of
directors) are timely made only if delivered to the New Caldera's principal
executive offices at least 120 days prior to the date of the meeting. Both
stockholder proposals and stockholder nominations of directors must include
certain information specified in the bylaws.

Amendment of Articles/Certificate of Incorporation And Bylaws

     SCO's articles of incorporation may be amended in accordance with the
applicable provisions the Corporation Law of the State of California, which
generally require the affirmative vote of the holders of a majority of
outstanding capital stock entitled to vote. SCO's bylaws may be amended by a
majority of the outstanding capital stock entitled to vote or by action of the
board of directors (except that the board may not amend the bylaws to change the
number or permissible range of numbers of authorized directors).

     New Caldera has reserved the right to amend, alter, change or repeal any
provision of its certificate of incorporation in accordance with the applicable
provisions of the General Corporation Law of the State of Delaware, which
generally require the affirmative vote of the holders of a majority of
outstanding capital stock entitled to vote to approve an amendment to a
certificate of incorporation. New Caldera's certificate of incorporation further
requires the affirmative vote of two-thirds the outstanding voting stock to
amend, alter, change or repeal the provisions of the certificate of
incorporation regarding directors, stockholder meetings, limitations of
directors' liability, indemnification, amendment of the bylaws, or amendment of
the certificate of incorporation.

     Pursuant to New Caldera's certificate of incorporation and bylaws, New
Caldera's bylaws may be altered, amended, or repealed by a majority vote of the
board of directors taken at any regular meeting or at a special meeting where
notice of the proposed alteration, amendment, or repeal is given. New Caldera's
bylaws may also be altered, amended, or repealed by a vote of 66 2/3% of the
outstanding voting stock.

Limitation of Liability of Directors

     SCO's articles of incorporation provide that the personal liability of
SCO's directors to SCO and its shareholders for monetary damages arising out of
a breach of the directors' fiduciary duties has been expressly eliminated to the
fullest extent permitted by the Corporation Law of the State of California.
Currently, the Corporation Law of the State of California permits a corporation
to include a provision in its articles of incorporation or bylaws enabling the
corporation to limit or eliminate the personal liability of its directors to the
corporation for damages arising out of a breach of the directors' fiduciary
duties, subject to certain limitations. The limitation of liability permitted by
California law does not apply to actions brought directly by shareholders (such
as a shareholder class action lawsuit) or to liabilities resulting from "acts or
omissions that show a reckless disregard for the director's duty to the
corporation or its shareholders in circumstances in which the director was
aware, or should have been aware, in the ordinary course of performing a
director's duties, of a risk of serious injury to the corporation or its
shareholders" or "acts or omissions that constitute an unexcused pattern of
inattention that amounts to an abdication of the director's duty to the
corporation or its shareholders."

     New Caldera's certificate of incorporation provides that the personal
liability of New Caldera's directors to New Caldera and its stockholders for
monetary damages arising out of a breach of the directors' fiduciary duties has
been expressly eliminated to the fullest extent permitted by the General
Corporation Law of the State of Delaware. In addition, New Caldera's certificate
of incorporation provides that if the General Corporation Law of the State of
Delaware is amended to authorize the further elimination or limitation of the
liability of a director, then the liability of New Caldera's directors will be
eliminated or limited to the fullest extent permitted by the General Corporation
Law of the State of

                                       138
<PAGE>   151

Delaware as so amended. Currently, the General Corporation Law of the State of
Delaware permits a corporation to include a provision in its certificate of
incorporation or bylaws enabling the corporation to limit or eliminate the
personal liability of its directors to the corporation or its stockholders for
damages arising out of a breach of the directors' fiduciary duties, subject to
certain limitations.

     While these provisions provide the directors of SCO and New Caldera with
protection against awards for monetary damages arising out of a breach of
fiduciary duties, they do not eliminate the duty itself. Accordingly, these
provisions will have no effect on the availability of equitable remedies such as
an injunction or rescission based upon a director's breach of his or her
fiduciary duties.

Indemnification of Directors and Officers

     SCO's bylaws require SCO to indemnify any person who is or was a director
or officer of SCO (or any predecessor of SCO) for any expenses, judgments and
fines actually incurred and amounts paid in settlement in connection with any
third party action, suit or other proceeding (other than a suit by or in the
right of SCO) to the fullest extent permitted by the Corporation Law of the
State of California. To the extent that SCO is required to indemnify a person
for expenses in accordance with the foregoing, SCO's bylaws require SCO to
advance such expenses to a person entitled to indemnification during a
proceeding if such person provides SCO with an undertaking to repay such
expenses if it is ultimately determined that such person is not entitled to
indemnification under SCO's bylaws. The indemnification provisions of SCO's
bylaws are not exclusive of any other rights that a person may have under any
bylaws, agreements between SCO and such person, or vote of SCO shareholders or
disinterested directors or otherwise.

     The Corporation Law of the State of California permits a corporation to
indemnify its directors, officers, employees and agents for any liability
arising out of an action or threatened action, other than an action by or in the
right of the corporation, to which such person is a party due to his or her
service as a director, officer, employee or agent, provided that such person
acted in good faith and in a manner he or she reasonably believed to be in the
best interests of the corporation, and with respect to any criminal action,
which he or she had no reason to believe was unlawful. The Corporation Law of
the State of California permits a corporation to indemnify its directors,
officers, employees and agents for any expenses actually and reasonably occurred
in connection with the defense or settlement of an action threatened action by
or in the right of the corporation to which such person is a party due to his or
her service as a director, officer, employee or agent, provided that such person
acted in good faith and in a manner he or she reasonably believed to be in the
best interests of the corporation, except that there may be no such
indemnification if the person is found liable to the corporation unless, in such
a case, the court determines that such person is entitled to indemnification.

     New Caldera's bylaws require New Caldera to indemnify any person who is or
was a director or officer of New Caldera (or any predecessor of New Caldera) for
any expenses, liabilities and losses reasonably incurred in connection with any
action, suit or proceeding to the fullest extent permitted by the General
Corporation Law of the State of Delaware. To the extent that New Caldera is
required to indemnify a person for expenses in accordance with the foregoing,
New Caldera is also required to advance expenses during a proceeding if the
person provides New Caldera with an undertaking to repay such expenses if it is
ultimately determined that such person is not entitled to indemnification under
New Caldera's bylaws. Notwithstanding the foregoing, New Caldera is not required
to advance expenses to any person against whom New Caldera brings a claim
alleging that such person willfully misappropriated corporate assets, disclosed
confidential information, or willfully and in bad faith breached such person's
duty to New Caldera or its stockholders.

     The General Corporation Law of the State of Delaware permits a corporation
to indemnify its directors, officers, employees and agents for any liability
arising out of an action or threatened action, other than an action by or in the
right of the corporation, to which such person is a party due to his or her
service as a director, officer, employee or agent, provided that such person
acted in good faith and in a manner he or she reasonably believed to be in, or
not opposed to, the best interests of the corporation, and

                                       139
<PAGE>   152

with respect to any criminal action, which he or she had no reason to believe
was unlawful. The General Corporation Law of the State of Delaware permits a
corporation to indemnify its directors, officers, employees and agents for any
liability arising out of an action or threatened action by or in the right of
the corporation to which such person is a party due to his or her service as a
director, officer, employee or agent, provided that such person acted in good
faith and in a manner he or she reasonably believed to be in, or not opposed to,
the best interests of the corporation, except that there may be no such
indemnification if the person is found liable to the corporation unless, in such
a case, the court determines that such person is entitled to indemnification.

         ADDITIONAL PROPOSALS TO BE VOTED UPON BY CALDERA STOCKHOLDERS

     At the Caldera special meeting of stockholders, you will be asked to
consider the following proposals in addition to Proposal One: Approval and
adoption of the combination:

     1. Amendments to the Caldera 1999 Omnibus Stock Incentive Plan to increase
        the number of shares reserved for issuance from 4,105,238 to 6,405,238
        and to provide for an automated director option grant program.

     2. Amendments to the 2000 Employee Stock Purchase Plan to increase the
        number of share reserved for issuance from 500,000 to 2,000,000.

     3. Amendment to the Caldera certificate of incorporation increasing the
        number of authorized shares of common stock of Caldera from 75,000,000
        to 175,000,000.

                  PROPOSAL TWO: APPROVAL OF AMENDMENTS TO THE
                              STOCK INCENTIVE PLAN

     Caldera's stockholders are being asked to approve a series of amendments to
Caldera's 1999 Omnibus Stock Incentive Plan (the "1999 Plan") that will effect
the following changes: (i) increase the maximum number of shares of common stock
authorized for issuance over the term of the 1999 Plan by an additional
2,300,000 shares to 6,405,238 shares, (ii) establish an automatic share increase
feature pursuant to which the number of shares available for issuance under the
1999 Plan will automatically increase, beginning with the 2000 calendar year, as
of November 1 of each year, by 3% of the total number of shares of common stock
outstanding on the previous October 31st, (iii) add a formula awards program
pursuant to which directors of Caldera will automatically be granted options to
purchase shares of common stock at specified times, including an option to
purchase 100,000 shares of common stock on the date of the annual shareholders
meeting during each even numbered calendar year.

     The purpose of the proposed share increase and automatic annual share
increase feature is to assure that a sufficient reserve of common stock is
available under the 1999 Plan to attract and retain the services of individuals
essential to Caldera's long-term growth and success. The purpose of establishing
the director formula awards program is to provide directors an inducement for
continued service on the board of directors of the Caldera.

     The 1999 Plan became effective on December 1, 1999, subject to the
requisite approval of the shareholders of Caldera, which was received on
December 1, 1999. The 1999 Plan was amended on March 10, 2000 to increase the
number of shares of common stock subject to the 1999 Plan and then again on July
14, 2000 to make various changes to the provisions governing awards granted
under the 1999 Plan. Unless earlier terminated by the Board, the right to grant
incentive awards under the 1999 Plan will terminate on December 1, 2009.
Incentive awards outstanding when the 1999 Plan terminates will remain in effect
according to their terms and the provisions of the 1999 Plan.

     The following is a summary of the principal features of the 1999 Plan,
including the amendments which will become effective upon stockholder approval
of this Proposal No. Two, together with the applicable tax and accounting
implications for Caldera and the participants. However, the summary does not
purport to be a complete description of all the provisions of the 1999 Plan. Any
stockholder of Caldera who wishes to obtain a copy of the actual plan document
may do so upon written request to Caldera's Chief Financial Officer at its
principal executive office located at 240 West Center Street Orem, Utah 84057.
The telephone number of such office is (801) 765-4999.

     You should note that, if the proposed transactions with New Caldera and SCO
are approved and consummated, New Caldera will assume the 1999 Plan, and all
incentive awards granted under the 1999 Plan will apply to shares of common
stock of New Caldera. All references in the following summary to "Caldera"
should be read to include all successors in interest to Caldera, including, if
the proposed transactions are consummated, New Caldera.

GENERAL

     The 1999 Plan is intended to promote the interests of Caldera and its
shareholders by providing directors, officers, employees and other persons,
including outside consultants, who are expected to make a long-term contribution
to the success of Caldera with appropriate incentives and rewards to encourage
them to enter into and continue in the employ of Caldera and to acquire a
proprietary interest in the long-term success of Caldera, thereby aligning their
interests more closely to the interests of Caldera's shareholders.

     In addition to the 1999 Plan, Caldera has previously adopted the 1998 Stock
Option Plan pursuant to which the Caldera has granted options to purchase
3,252,088 shares of common stock, of which 276,433 options have been exercised
or cancelled and 2,975,655 options remain outstanding. Upon approval of the 1999
Plan, the 1998 Stock Option Plan was terminated. Accordingly, although
previously granted options remain outstanding and subject to the terms of the
1998 Stock Option Plan, Caldera may not grant any

                                       142
<PAGE>   155

new options (upon the expiration of previously granted options or otherwise)
under the 1998 Stock Option Plan.

SHARES COVERED BY THE 1999 PLAN

     The 1999 Plan presently authorizes the grant of incentive awards with
respect to an aggregate of 4,105,238 shares of common stock. If the stockholders
approve Proposal Number Two, the number of shares authorized for incentive
awards under the 1999 Plan will increase to 6,405,238, and such number will
automatically increase, as of November 1 of each year beginning in 2000, by 3%
of the total number of shares of common stock outstanding on the previous
October 31st. Notwithstanding a greater increase in the number of shares subject
to the 1999 Plan, the number of shares that may be issued upon the exercise of
incentive stock options under the 1999 Plan shall in no event exceed 6,405,238
shares, increased by 100,000 shares on November 1 of each year between 2000 and
2008.

     Shares issued pursuant to the 1999 Plan may be authorized and unissued
shares, treasury shares or shares acquired by Caldera for purposes of the 1999
Plan. Generally, shares subject to an incentive award that remain unissued upon
expiration, cancellation, surrender, exchange, or termination of the incentive
award will be available for other incentive awards under the 1999 Plan.

CHANGES IN CAPITALIZATION

     In the event that the committee appointed by the Board to administer the
1999 Plan (the "Committee") determines that any dividend or other distribution,
stock split, reverse stock split, recapitalization, reorganization, merger,
consolidation, spin-off, combination, repurchase, share exchange, or other
similar corporate transaction or event affects the common stock such that an
adjustment is appropriate in order to prevent dilution or enlargement of the
rights of participants under the 1999 Plan, then the Committee will make such
equitable changes or adjustments as it deems necessary to the aggregate number
of shares available under the 1999 Plan, the number and kinds of shares that may
thereafter be used for any incentive award, and the number of shares subject to
and exercise price, grant price, or purchase price of each outstanding incentive
award.

ADMINISTRATION

     The 1999 Plan is administered by the Committee, which consists of two or
more persons appointed (and removable) by the board of directors in its
discretion, each of whom must be an "outside director" within the meaning of
Section 162(m) of the Code and a "nonemployee director" within the meaning of
Rule 16b-3 promulgated under the Securities Exchange Act 1934, as amended. The
Committee is authorized, among other things, to do the following:

     - to construe, interpret and implement the provisions of the 1999 Plan;

     - to select the persons to whom incentive awards will be granted;

     - to determine when incentive awards will be granted;

     - to determine the terms and conditions of such incentive awards;

     - to establish the performance criteria under which incentive awards will
       be granted;

     - to determine when and under what circumstances an incentive award can be
       settled, canceled, forfeited, exchanged, or surrendered;

     - to make rules with respect to the 1999 Plan;

     - to determine the terms and provisions of award agreements, which are
       required to accompany and evidence any incentive award under the Plan
       (the terms of which are accepted by any Participant through the act of
       accepting the incentive award); and

                                       143
<PAGE>   156

     - to make all other determinations deemed necessary or advisable for the
       administration of the 1999 Plan.

     The 1999 Plan provides that no member of the Committee shall be liable for
any action, omission or determination relating to the 1999 Plan and that Caldera
shall indemnify and hold harmless each member of the Committee and each other
director or employee of Caldera to whom any duty or power relating to the
administration or interpretation of the 1999 Plan has been delegated against any
cost, expense or liability arising out of any action, omission or determination
relating to the 1999 Plan, if, in either case, such action, omission or
determination was taken or made by such member, director or employee in good
faith and in a manner such member, director or employee reasonably believed to
be in or not opposed to the best interests of Caldera.

ELIGIBILITY

     The persons who are eligible to receive incentive awards pursuant to the
1999 Plan include all employees and directors of Caldera and its subsidiaries
and such other persons, including outside consultants, whom the Committee
determines are expected to make a contribution to Caldera. The Committee may
grant incentive awards to any, all or none of such eligible persons at any time,
from time to time, during the term of the 1999 Plan. "Participants" in the 1999
Plan are persons who both are eligible to receive an incentive award pursuant to
the 1999 Plan and to whom an incentive award is granted pursuant to the 1999
Plan, and, upon his or her death, his or her successors, heirs, executors and
administrators, as the case may be.

INCENTIVE AWARDS UNDER THE 1999 PLAN

     Incentive awards under the 1999 Plan may be made in the form of (i)
incentive stock options, (ii) non-qualified stock options, (iii) tandem or
stand-alone stock appreciation rights, (iv) restricted stock, (v) phantom stock
and (vi) stock bonuses. Each incentive award granted under the 1999 Plan (except
an unconditional stock bonus) shall be evidenced by an award agreement
containing such provisions as the Committee shall deem desirable.

STOCK OPTIONS

     General. The Committee determines, and sets forth in the applicable award
agreement, whether an option is an incentive stock option or a non-qualified
stock option, the vesting schedule of each option, and the expiration date of
each option; provided, however, no incentive stock option may be exercisable
more than 10 years after the date of grant. The purchase price per share payable
upon the exercise of an option is established by the Committee. With respect to
non-qualified stock options, the Option Exercise Price may be less than the fair
market value of a share of our common stock on the date such option is granted.
With respect to incentive stock options, the Option Exercise Price may not be
less than the fair market value of a share of common stock on the date the
option is granted. During the period our common stock is traded on the Nasdaq
National Market, the fair market value of a share of common stock is the closing
sales price of a share of our common stock on such market on the most recent
pending on which there was a sale of our common stock on such market. The
closing sales price of a share of our common stock on September 11, 2000 was
$7.06. Unless the applicable award agreement provides otherwise, an option
becomes cumulatively exercisable as to 25 percent of the shares covered thereby
on each of the first, second, third and fourth anniversaries of the date of
grant. Only individuals who are employees of Caldera or any subsidiary of
Caldera as of the date of the grant are eligible to receive incentive stock
options.

     Exercise of Options. An option may be exercised by delivering notice to
Caldera's Secretary no later than one business day in advance of the effective
date of the proposed exercise. Payment for shares of

                                       144
<PAGE>   157

common stock purchased upon the exercise of an option shall be made on the
effective date of such exercise by one or a combination of the following means:

     - in cash, by certified check, bank cashier's check or wire transfer;

     - subject to any restrictions imposed by applicable securities laws, by
       delivering a properly executed exercise notice to Caldera together with a
       copy of irrevocable instructions to a broker to deliver promptly to
       Caldera the amount of sale or loan proceeds to pay the full amount of the
       purchase price;

     - by delivering shares of common stock owned by the Participant with
       appropriate stock powers;

     - by electing to have Caldera retain shares of common stock which would
       otherwise be issued on the exercise of the option; or

     - any combination of the foregoing forms, as approved by the Committee.

     Certain Limitations on Incentive Stock Options. The total number of shares
of common stock subject to incentive awards awarded to any employee during any
tax year of Caldera shall not exceed 200,000 shares of common stock.

     To the extent that the aggregate fair market value of shares of common
stock with respect to which incentive stock options are exercisable for the
first time by a Participant during any calendar year under the 1999 Plan and any
other stock option plan of Caldera (or any subsidiary of Caldera) exceed
$100,000, such options are treated as non-qualified stock options. Fair market
value in this context refers to the value on the date on which each such
incentive stock option is granted.

     In addition, the 1999 Plan prevents the issuance of any incentive stock
options to an individual if, at the time of such proposed grant, the individual
owns stock that represents more than ten percent (10%) of the total combined
voting power of all classes of stock of Caldera. This limitation does not apply
if the Option Exercise Price per share of the proposed incentive stock option is
at least one hundred ten percent (110%) of the fair market value of a share of
common stock at the time such proposed incentive stock option is granted and it
is not exercisable after five years from the date of grant.

     Termination of Employment. In the event that the employment or service as a
director of a Participant with Caldera or a subsidiary of Caldera is terminated
by the employee or by Caldera for cause, unless the applicable award agreement
provides otherwise, (i) options granted to such Participant, to the extent that
they are exercisable at the time of such termination, remain exercisable until
the date that is 30 after such termination, on which date they shall expire, and
(ii) options granted to such Participant, to the extent that they were not
exercisable at the time of such termination, expire at the close of business on
the date of such termination. No option shall be exercisable after the
expiration of its original term.

     In the event that the employment or service as a director of a Participant
with Caldera or a subsidiary of Caldera is terminated by Caldera in connection
with a reduction in force or by Caldera for any other reason other than death,
disability or cause, unless the applicable award agreement provides otherwise,
(i) options granted to such Participant, to the extent that they are exercisable
at the time of such termination, remain exercisable until the date that is 90
days (120 days in the case of a non-qualified option) after such termination, on
which date they shall expire, and (ii) options granted to such Participant, to
the extent that they were not exercisable at the time of such termination,
expire at the close of business on the date of such termination. No option shall
be exercisable after the expiration of its original term.

     In the event that the employment of a Participant with Caldera or a
subsidiary of Caldera is terminated by reason of death or disability of the
Participant, unless the applicable award agreement provides otherwise, (i)
options granted to such Participant, to the extent that they are exercisable at
the time of such termination, remain exercisable until the date that is one year
after such termination, on which date they shall expire, and (ii) options
granted to such Participant, to the extent that they were not

                                       145
<PAGE>   158

exercisable at the time of such termination, expire at the close of business on
the date of such termination. No option shall be exercisable after the
expiration of its original term.

     Effect of a Change in Control. Under the 1999 Plan, a "Change in Control"
includes the following:

     - acquisition by any person (with certain exceptions), directly or
       indirectly, of fifty percent (50%) or more of the combined voting power
       of Caldera's then outstanding securities;

     - during a period of not more than two consecutive years following the
       adoption of the 1999 Plan, individuals who at the beginning of such
       period constitute the Board and any new director (with certain
       exemptions) whose election by the Board or nomination for election was
       approved by 2/3 of the directors then still in office who were either
       directors when the 1999 Plan was adopted or approved as provided herein
       cease to constitute a majority of the Board,

     - Caldera's shareholders approve and Caldera consummates a merger or
       consolidation, except for such a merger or consolidation after which the
       shareholders prior to such merger or consolidation retain more than fifty
       percent (50%) of the combined voting power of the corporation surviving
       the merger and except for a merger or consolidation effected to implement
       a recapitalization of Caldera in which no person acquired more than fifty
       percent (50%) of the combined voting power of Caldera's then outstanding
       securities; and

     - Caldera's shareholders approve a plan of complete liquidation of Caldera
       or an agreement for the sale or disposition by Caldera of all or
       substantially all of Caldera's assets.

     Upon the occurrence of a Change in Control, each outstanding option granted
under the 1999 Incentive that has vested may be, at Caldera's discretion, (i)
cashed out, (ii) converted to options of the acquiring entity, (iii) assumed by
the acquiring entity, or (iv) or otherwise disposed of in the manner provided in
any shareholder-approved agreement or plan governing such Change in Control. In
the absence of any governing provisions in any shareholder-approved agreement or
plan governing such Change in Control, the Committee may, on a case-by-case
basis, require any vested, exercisable options that remain outstanding following
a Change in Control to be cashed out and terminated in exchange for a lump sum
cash payment, shares of the acquiring entity or a combination thereof equal in
value to the fair market value of the option.

     In the event of a Change in Control , each outstanding option granted under
the 1999 Plan that has not vested shall terminate, unless (i) otherwise provided
in the shareholder-approved agreement or plan governing such Change in Control,
or (ii) the Committee in its sole discretion on a case-by-case basis elects in
writing to waive termination.

TANDEM STOCK APPRECIATION RIGHTS

     General. The Committee may grant, in connection with any option granted
under the 1999 Plan, tandem stock appreciation rights ("SARs") relating to a
number of shares of common stock less than or equal to the number of shares of
common stock subject to the related option. The exercise of a tandem SAR with
respect to any number of shares of common stock, which occurs through notice to
Caldera's Secretary no less than one business day in advance of the effective
date of the proposed exercise, entitles the Participant to a cash payment, for
each such share, equal to the excess of (i) the fair market value of a share of
common stock on the exercise date over (ii) the Option Exercise Price per share
of the related option.

     Term and Exercisability. A tandem SAR is exercisable (i) only if and to the
extent that its related option is exercisable and (ii) only if at the time of
such exercise, the fair market value of a share of common stock exceeds the
Option Exercise Price per share of the related option. The exercise of a tandem
SAR with respect to a number of shares of common stock causes the immediate and
automatic cancellation of its related option with respect to an equal number of
shares. The exercise of an option, or the cancellation, termination or
expiration of an option with respect to a number of shares of common

                                       146
<PAGE>   159

stock generally causes the automatic and immediate cancellation of any related
tandem SARs. Such tandem SARs are canceled in the order in which they became
exercisable. The 1999 Plan allows partial exercise of tandem SAR rights,
provided that no such partial exercise is for less than a number of shares
having an aggregate Option Exercise Price of less than $1,000.

STAND-ALONE STOCK APPRECIATION RIGHTS

     The Committee may also grant stand-alone SARs independently of any option
granted under the 1999 Plan. The exercise of a stand-alone SAR with respect to
any number of shares of common stock entitles the Participant to a cash payment,
for each such share, equal to the excess of (i) the fair market value of a share
of common stock on the exercise date over (ii) the "Reference Value" per share
of the stand-alone SAR. The "Reference Value" is the greater of the fair market
value per share on the date of grant or the Reference Value set by the
Committee. Unless the applicable award agreement provides otherwise, a
stand-alone SAR becomes cumulatively exercisable as to 25 percent of the shares
covered thereby on each of the first, second, third and fourth anniversaries of
the date of grant. The Committee determines the expiration date of each
stand-alone SAR. The termination of a Participant's employment with Caldera or
the occurrence of an event that constitutes a Change in Control has the same
effect on a stand-alone SAR as on an option. The 1999 Plan allows for the
partial exercise of any stand-alone SAR, provided that no partial exercise shall
be for an aggregate Reference Value of less than $1,000.

RESTRICTED STOCK

     General. The Committee may grant restricted shares of common stock to such
persons, in such amounts, and subject to such terms and conditions as the
Committee determines in its discretion. The Committee establishes vesting dates
for restricted stock, and, if awards of restricted stock are intended to be
"performance based compensation" for Section 162(m) of the Code, awards of
restricted stock must be contingent on the attainment by Caldera or a subsidiary
of Caldera of one or more pre-established performance goals (the "Performance
Goals") established by the Committee. The Performance Goals are based on the
attainment by Caldera (and/or its subsidiaries, if applicable) of any one or
more of the following criteria:

     - a specified percentage return on total stockholder equity of Caldera;

     - a specified percentage increase in earnings per share of common stock;

     - a specified percentage increase in net income of Caldera; and/or

     - a specified percentage increase in profit before taxation of Caldera.

The Committee in its discretion may require that any dividends paid on shares of
restricted stock be held in escrow until all restrictions on such shares have
lapsed. Performance goals are measured according to generally accepted
accounting principles and must be certified as being achieved by the Committee.

     Restrictions on Transfer Prior to Vesting. When shares of restricted stock
are initially granted, the certificates representing such shares bear a legend
stating that the transferability of such shares is subject to the 1999 Plan and
the governing award agreement, and, unless the Committee determines otherwise,
such certificates are retained by Caldera, along with stock powers for the
benefit of Caldera relating to such shares. Prior to the vesting of a share of
restricted stock, no transfer of a Participant's rights with respect to such
share, whether voluntary or involuntary, by operation of law or otherwise, is
permitted. Immediately upon any attempt to transfer such rights, such share, and
all of the rights related thereto, will be forfeited by the Participant. Upon
the vesting of a share of restricted stock pursuant to the terms of the
applicable award agreement, such restrictions on transfer lapse, and Caldera is
required to issue a certificate without restrictive legend (other than any
legend that may be required by law). The Committee may impose at the time of
granting any restricted stock any vesting conditions that it, in its absolute
discretion, deems appropriate.

                                       147
<PAGE>   160

     Effect of Termination of Employment or Removal from Board. Upon the
termination of a Participant's employment or service with Caldera or any
subsidiary of Caldera for any reason other than cause, any and all non-vested
shares of restricted stock are immediately forfeited by the Participant and
transferred to Caldera, unless the applicable restricted stock Agreement
provides otherwise or, in its sole discretion, the Committee gives notice to the
Participant within thirty (30) days of the termination that the Participant
shall continue to be the owner of the restricted stock. If shares of restricted
stock are so forfeited, Caldera also has the right to require the return of all
dividends paid on such shares, whether by termination of any escrow arrangement
under which such dividends are held or otherwise. In the event of the
termination of a Participant's employment for cause, all shares of restricted
stock granted to such Participant that have not vested as of the date of such
termination shall immediately be returned to Caldera, together with any
dividends paid on such shares.

     Effect of Change in Control. Upon the occurrence of an event that
constitutes a Change in Control, all restrictions on outstanding vested shares
of restricted stock immediately lapse and all outstanding shares of restricted
stock that have not vested as of the date the Change in Control occurs
immediately expire and are cancelled.

PHANTOM STOCK

     General. The Committee may grant shares of phantom stock to such persons,
in such amounts, and subject to such vesting terms and conditions as the
Committee determines in its discretion. If the vesting requirements specified by
the Committee are met, the grantee of phantom stock will receive, within thirty
(30) days of the day such phantom stock vests, a cash payment equal to the sum
of (i) the fair market value of the shares of common stock on the date on which
such share of phantom stock vests and (ii) the aggregate amount of cash
dividends paid with respect to a share of common stock during the period
commencing on the date on which the share of phantom stock was granted and
terminating on the date on which such share vests. If awards of phantom stock
granted to Executive Officers of Caldera are intended to be "performance based
compensation" for Section 162(m) of the Code, the vesting of such awards of
phantom stock must be contingent on the attainment by Caldera or a subsidiary of
Caldera of any one or more of the Performance Goals noted above in the
discussion of restricted stock awards. Attainment of performance goals will be
measured based upon generally accepted accounting principles and must be
certified by the Committee as having been achieved.

     Termination of Employment. Except as provided in the applicable award
agreement, shares of phantom stock that have not vested, together with any
dividends credited on such shares, will be forfeited upon the Participant's
termination of employment for any reason other than cause. Termination for cause
results in the immediate forfeiture of all shares of phantom stock granted to
the terminated Participant, together with any dividends credited on such shares.

     Effect of Change in Control. Upon the occurrence of an event that
constitutes a Change in Control, all outstanding shares of phantom stock that
have not yet vested prior to the date constituting the Change in Control shall
immediately expire and be cancelled.

STOCK BONUS

     The Committee may grant bonuses comprised of shares of common stock free of
restrictions to such persons, in such amounts, as the Committee determines in
its discretion.

AMENDMENT OR TERMINATION OF THE 1999 PLAN

     The Board may suspend, revise, terminate or amend the 1999 Plan at any
time; provided, however, that shareholder approval must be obtained if and to
the extent that the Board deems it appropriate to satisfy Section 162(m) of the
Code, Section 422 of the Code or the rules of any stock exchange on which the
common stock is listed. No action under the 1999 Plan may, without the consent
of the Participant, reduce the Participant's rights under any outstanding
incentive award.

                                       148
<PAGE>   161

TRANSFERABILITY OF AWARDS DURING PARTICIPANT'S LIFETIME/FORFEITURE FOR FAILURE
TO COMPLY

     During a Participant's lifetime, the Committee may permit or prohibit, in
its discretion, the transfer, assignment or other encumbrance of an outstanding
option or outstanding shares of restricted stock unless such option is an
incentive stock option. To the extent the Committee and respective participant
desire that incentive stock options shall remain incentive stock options,
incentive stock options are nontransferable except upon death. Subject to any
conditions the Committee imposes, options granted under the Plan may be
transferred to an immediate family member, if notice of such transfer is
received in exchange for such transfer to Caldera and no consideration is given
for the transfer. Rights with respect to other incentive awards granted under
the 1999 Plan may not be transferred, assigned or pledged.

     Failure by a Participant (or beneficiary or transferee) to comply with any
of the terms and conditions of the 1999 Plan or the applicable award agreement,
unless such failure is remedied by such Participant (or beneficiary or
transferee) within ten days after notice of such failure by the Committee, is
grounds for the cancellation and forfeiture of the respective incentive award,
in whole or in part, as the Committee, in its absolute discretion, may
determine.

PROPOSED DIRECTORS FORMULA AWARD PROGRAM

     If Proposal No. Two is approved by the stockholders, the 1999 Plan will be
amended to establish a program providing for the automatic grant of options to
directors of Caldera at specified times. If approved by the stockholders of
Caldera, the proposed formula awards program will have the following features:

GENERAL PROVISIONS OF PROPOSED FORMULA AWARD PROGRAM.

     - Grant in 2002 Calendar Year. Each director who is elected to serve or
       continues to serve as a director of Caldera following the date of the
       regularly scheduled annual meeting of shareholders during the 2002
       calendar year will automatically be granted an option to purchase 100,000
       shares of common stock at an Option Exercise Price equal to the fair
       market value of a share of common stock on the date of such annual
       meeting.

     - Grant in Subsequent Even-Number Calendar Years. Each director who is
       elected to serve or continues to serve as a director of Caldera following
       the date of the regularly scheduled annual meeting during each
       even-numbered calendar year beginning with 2004 will automatically be
       granted an option to purchase 100,000 shares of common stock at an Option
       Exercise Price equal to the fair market value of a share of common stock
       on the date of such annual meeting.

     - Grant to Directors First Elected Between Even-Numbered Calendar
       Years. Each director who is first elected or appointed to serve as a
       director other than at an annual meeting of shareholders in an
       even-number calendar year will automatically be granted, upon the
       commencement of such service, an option to purchase a number of shares of
       common stock equal to the product of (i) a fraction, the numerator of
       which is the number of full calendar months between the date of such
       election or appointment and March 1 of the next even-numbered calendar
       year, and the denominator of which is 24, multiplied by (ii) 100,000.
       Such options shall have an Option Exercise Price equal to the fair market
       value of a share of common stock on the date of grant.

     - Top-Up Grant For Certain Directors. Each director whose existing options
       are all scheduled to vest prior to March 1, 2002 will automatically be
       granted, on the date all such options vest, an option to purchase a
       number of shares of common stock equal to the product of (i) a fraction,
       the numerator of which is the number of full calendar months between the
       date all such options vest and March 1, 2002, and the denominator of
       which is 24, multiplied by (ii) 100,000. Such options shall have an
       Option Exercise Price equal to the fair market value of a share of common
       stock on the date of grant. All options granted under the director
       formula awards program will vest 50% on the first anniversary of the date
       of grant and 50% on the second anniversary of the date of grant.

                                       149
<PAGE>   162

     Limitations on Options Granted. No option may be granted pursuant to the
formula awards program on a date when the number of shares of common stock
authorized for issuance pursuant to the 1999 Plan is less than the sum of (i)
all shares of common stock issued under the 1999 Plan, (ii) all shares of common
stock subject to outstanding options, and (iii) all options that would, but for
the effect of this limitation, be granted on that date.

     Other Provisions. Options granted under the formula awards program are
otherwise generally subject to the same terms and conditions as other options
granted under the 1999 Plan.

WITHHOLDING TAXES

     Whenever cash is to be paid pursuant to an incentive award, Caldera has the
right to deduct therefrom an amount sufficient to satisfy any federal, state and
local withholding tax requirements related thereto. Whenever shares of common
stock are to be delivered pursuant to an incentive award, Caldera has the right
to require the Participant to remit to Caldera in cash an amount sufficient to
satisfy any federal, state and local withholding tax requirements related
thereto. With the approval of the Committee, a Participant may satisfy the
foregoing requirement by electing to have Caldera withhold from delivery shares
of common stock having a fair market value equal to the amount of tax to be
withheld.

COMPLIANCE WITH TAX LAWS

     The 1999 Plan is intended to provide performance-based compensation and
thereby avoid the limitations of Section 162(m) of the Code. Section 162(m)
denies a deduction by an employer for certain compensation in excess of $1
million per year paid by a publicly-traded corporation to the following
individuals who are employed at the end of the employer's taxable year ("Covered
Employees"): the chief executive officer and the four most highly compensated
executive officers (other than the chief executive officer), for whom
compensation disclosure is required under the proxy rules. Certain compensation,
including compensation based on the attainment of performance goals, is excluded
from this deduction limit if certain requirements are met. Among the
requirements for compensation to qualify for "performance based" exception to
Section 162(m) is that the material terms pursuant to which the compensation is
to be paid be disclosed to and approved by the shareholders in a separate vote
prior to the payment. Accordingly, because the 1999 Plan has been approved by
the shareholders of Caldera and the Committee intends to administer the Plan so
that the other conditions of Code Section 162(m) relating to performance-based
compensation are satisfied, compensation paid to Covered Employees pursuant to
the 1999 Plan will not be subject to the deduction limit of Section 162(m).

FEDERAL INCOME TAX CONSEQUENCES

     The following discussion is a brief summary of the principal United States
Federal income tax consequences relating to incentive awards under the 1999
Plan. This discussion is based on currently existing provisions of the Code,
existing and proposed Treasury Regulations promulgated 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 shareholders described herein. Shareholders should be aware that
this discussion does not deal with all United States Federal income tax
considerations that may be relevant to an individual shareholder granted
incentive awards pursuant to the 1999 Plan. ACCORDINGLY, SHAREHOLDERS AND
INCENTIVE AWARD RECIPIENTS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS AS TO THE
SPECIFIC TAX CONSEQUENCES RELATING TO INCENTIVE AWARDS UNDER THE 1999 PLAN.

     Non-Qualified Stock Options. An optionee will not recognize any taxable
income upon the grant of a non-qualified stock option. Caldera will not be
entitled to a tax deduction with respect to the grant of a non-qualified stock
option. Upon exercise of a non-qualified stock option, the excess of the fair
market value of the common stock on the exercise date over the Option Exercise
Price will be taxable as compensation income to the optionee and will be subject
to applicable withholding taxes. Caldera will generally be entitled to a tax
deduction at such time in the amount of such compensation income. The

                                       150
<PAGE>   163

optionee's tax basis for the common stock received pursuant to the exercise of a
non-qualified stock option will equal the sum of the compensation income
recognized and the exercise price.

     In the event of a sale of common stock received upon the exercise of a
non-qualified stock option, any appreciation or depreciation after the exercise
date generally will be taxed as capital gain or loss and will be long-term
capital gain or loss if the holding period for such common stock is more than
one year.

     The exercise of a non-qualified stock option through the delivery of
previously acquired stock will generally be treated as a non-taxable, like-kind
exchange as to the number of shares surrendered and the identical number of
shares received under the option. That number of shares will take the same basis
and, for capital gains purposes, the same holding period as the shares that are
given up. The value of the shares received upon such an exchange that are in
excess of the number given up will be includible as ordinary income to the
participant at the time of the exercise. The excess shares will have a new
holding period for capital gain purposes and a basis equal to the value of such
shares determined at the time of exercise.

     Neither the Participant nor the transferee will realize taxable income at
the time of a non-arm's-length transfer of a non-qualified stock option as a
gift. Upon the subsequent exercise of the option by the transferee, the
Participant will realize ordinary income in an amount equal to the excess of the
fair market value of the shares on the date of exercise over the option price.
Upon a subsequent disposition of the shares by the transferee, the transferee
will generally realize short-term or long-term capital gain or loss, with the
basis for computing such gain or loss equal to the fair market value of the
stock at the time of exercise. If a participant makes a gift of an option, and
surrenders all dominion and control of the option, the gift should be complete
for Federal gift tax purposes at the time of transfer and should be valued at
that time (or, if later, at the time the option becomes vested). For gift and
estate tax purposes, the gift of an option would generally cause the option (and
the stock acquired by exercise) to be excluded from the participant's estate.
Special rules may apply if the participant makes a gift of an award to a charity
or to a "living trust" under which the participant retains the right to revoke
the trust or substantially alter its terms.

     Incentive Stock Options. An optionee generally will not recognize any
taxable income at the time of grant or timely exercise of an incentive stock
option for regular U.S. federal income tax purposes, and Caldera will not be
entitled to a tax deduction with respect to such grant or exercise. Exercise of
an incentive stock option may, however, give rise to taxable compensation income
subject to applicable withholding taxes, and a tax deduction to Caldera, if the
optionee subsequently engages in a "disqualifying disposition," as described
below. Additionally, the spread between the fair-market value of shares obtained
upon exercise of an incentive stock option and the exercise price is an
adjustment to alternative minimum taxable income and may result in the option
holder having to pay federal alternative minimum tax for the year of exercise.

     A sale or exchange by an optionee of shares acquired through the exercise
of an incentive stock option more than one year after the transfer of the shares
to such optionee and more than two years after the date of grant of the
incentive stock option will result in any difference between the net sale
proceeds and the exercise price paid being treated a long-term capital gain (or
loss) to the optionee. If such sale or exchange (including inter vivos gifts)
takes place within two years after the date of grant of the incentive stock
option or within one year from the date of transfer of the incentive stock
option shares to the optionee, such sale or exchange will generally constitute a
"disqualifying disposition" of such shares. A disqualifying disposition that
will have the following results: any excess of (i) the lesser of (a) the fair
market value of the shares at the time of exercise of the incentive stock option
and (b) the amount realized on such disqualifying disposition of the shares over
(ii) the Option Exercise Price of such shares, will be ordinary income to the
optionee, subject to applicable reporting requirements, and Caldera will be
entitled to a tax deduction in the amount of such income. Any further gain
generally will qualify as capital gain and will not result in any deduction by
Caldera.

     The exercise of an incentive stock option through the exchange of
previously acquired Stock will generally be treated in the same manner as such
an exchange would be treated in connection with the exercise of a non-qualified
stock option; that is, as a non-taxable, like-kind exchange as to the number of
                                       151
<PAGE>   164

shares given up and the identical number of shares received under the option.
That number of shares will take the same basis and, for capital gain purposes,
the same holding period as the shares that are given up. However, such holding
period will not be credited for purposes of the one-year holding period required
for the new shares to receive incentive stock option treatment. Shares received
in excess of the number of shares given up will have a new holding period and
will have a basis of zero or, if any cash was paid as part of the exercise
price, the excess shares received will have a basis equal to the amount of the
cash. If a disqualifying disposition (a disposition before the end of the
applicable holding period) occurs with respect to any of the shares received
from the exchange, it will be treated as a disqualifying disposition of the
shares with the lowest basis.

     If the exercise price of an incentive stock option is paid with shares of
stock of Caldera acquired through a prior exercise of an incentive stock option,
gain will be realized on the shares given up (and will be taxed as ordinary
income) if those shares have not been held for the minimum incentive stock
option holding period (two years form the date of grant and one year from the
date of transfer), but the exchange will not affect the tax treatment, as
described in the immediately preceding paragraph, of the shares received.

     Restricted Stock. A grantee of restricted stock will not recognize any
income upon the receipt of restricted stock unless the holder elects under
Section 83(b) of the Code within thirty days of such receipt, to recognize
ordinary income in an amount equal to the fair market value of the restricted
stock at the time of receipt. If the election is made, the holder will not be
allowed a deduction for amounts subsequently required to be returned to Caldera.
Any Section 83(b) election must be filed with the IRS within the applicable
30-day period. If the Section 83(b) election is not made, the holder will
generally recognize ordinary income, on the date that the restrictions to which
the restricted stock are subject are removed, in an amount equal to the fair
market value of such shares on such date, less any amount paid for the shares.
At that time the holder will recognize ordinary income, subject to applicable
reporting and withholding requirements, and Caldera generally will be entitled
to a deduction in the same amount.

     Generally, upon a sale or other disposition of restricted stock with
respect to which the holder has recognized ordinary income (i.e., a Section
83(b) election was previously made or the restrictions were previously removed),
the holder will recognize capital gain or loss in an amount equal to the
difference between the amount realized on such sale or other disposition and the
holder's basis in such shares. Such gain or loss will be long-term capital gain
or loss if the holding period for such shares is more than one year.

     Other Incentive Awards. The grant of a stock appreciation right or phantom
stock award will not result in taxable income to the grantee or in a tax
deduction for Caldera. Upon the settlement of such a right or award, the grantee
will recognize ordinary income equal to the aggregate value of the payment
received, subject to applicable reporting and withholding requirements, and
Caldera generally will be entitled to a tax deduction in the same amount. A
stock bonus generally will result in compensation income for the grantee and a
tax deduction for Caldera, equal to the fair market value of the shares of
common stock granted.

     Withholding of Taxes. Pursuant to the plan, Caldera may deduct, from any
payment or distribution of shares under the plan, the amount of any tax required
by law to be withheld with respect to such payment, or may require the
Participant to pay such amount to Caldera prior to, and as a condition of,
making such payment or distribution. Subject to rules and limitations
established by the Committee, a participant may elect to satisfy the withholding
required, in whole or in part, either by having Caldera withhold shares of
common stock from any payment under the plan or by the Participant delivering
shares of common stock to Caldera. Any election must be made in writing on or
before the date when the amount of taxes to be withheld is determined. The
portion of the withholding that is so satisfied will be determined using the
fair market value of the common stock on the date when the amount of taxes to be
withheld is determined.

     The use of shares of common stock to satisfy any withholding requirement
will be treated, for federal income tax purposes, as a sale of such shares for
an amount equal to the fair market value of the stock on
                                       152
<PAGE>   165

the date when the amount of taxes to be withheld is determined. If
previously-owned shares of common stock are delivered by a Participant to
satisfy a withholding requirement, the disposition of such shares would result
in the recognition of gain or loss by the participant for tax purposes,
depending on whether the basis in the delivered shares is less than or greater
than the fair market value of the shares at the time of disposition.

     Change in Control. Any acceleration of the vesting or payment of awards
under the 1999 Plan in the event of a change in control in Caldera may cause
part or all of the consideration involved to be treated as an "excess parachute
payment" under the Internal Revenue Code, which may subject the participant to a
20% excise tax and which may not be deductible by Caldera.

VALUE OF BENEFITS TO CERTAIN PERSONS

     If Proposal No. Two is approved by the stockholders, and the directors
formula awards program is adopted, any current or future director of the Company
that is elected to serve or continues to serve as a director of Caldera
following the date of the regularly scheduled annual meeting of stockholders
during the 2002 calendar year and each even number thereafter will, subject to
the availability of a sufficient number of shares under the 1999 Plan, be
granted an option to purchase 100,000 shares of common stock at an Option
Exercise Price equal to the fair market value of a share of common stock on the
date of such annual meeting.

     Except as described in the preceding paragraph, Caldera is unable to
determine the amount of benefits that may be received in the future by
participants under the 1999 Plan if the proposed amendments are approved, as the
receipt of incentive awards under the 1999 Plan is generally subject to the
discretion of the Committee.

STOCK AWARDS

     The table below shows, as to each of Caldera's executive officers named in
the Summary Compensation Table of the Executive Compensation and Related
Information section of this Proxy Statement and the various indicated
individuals and groups, the number of shares of common stock subject to options
granted under the 1999 Plan between December 1, 1999, the effective date of the
1999 Plan and September 1, 2000, together with the weighted average exercise
price per share.

(1) To date, no restricted stock, phantom stock, stock bonus, or stock
    appreciation right awards have been granted under the 1999 Plan.

     As of September 1, 2000, options covering 3,992,432 shares of common stock
were outstanding under the 1999 Plan, 2,398,924 shares remained available for
future option grant or direct issuance (assuming stockholder approval of the
increase which forms part of this Proposal), and 13,882 shares have been issued
pursuant to the exercise of outstanding options under the 1999 Plan.

DEDUCTIBILITY OF EXECUTIVE COMPENSATION

     Caldera anticipates that any compensation deemed paid by it in connection
with the disqualifying disposition of incentive stock option shares or the
exercise of non-statutory options granted with exercise prices equal to the fair
market value of the shares on the grant date will qualify as performance-based
compensation for purposes of Code Section 162(m) and will not have to be taken
into account for purposes of the $1 million limitation per covered individual on
the deductibility of the compensation paid to certain executive officers of
Caldera. Accordingly, all compensation deemed paid under the 1999 Plan will
remain deductible by Caldera without limitation under Code Section 162(m).

ACCOUNTING TREATMENT

     Option grants or stock issuances with exercise or issue prices less than
the fair market value of the shares on the grant or issue date will result in a
direct compensation expense to Caldera's earnings equal to the difference
between the exercise or issue price and the fair market value of the shares on
the grant or issue date. Such expense will be recognized by Caldera over the
period that the option shares or issued shares are to vest. Option grants or
stock issuances at 100% of fair market value will not result in any direct
charge to Caldera's earnings. However, the fair value of those options is
required to be disclosed in the notes to Caldera's financial statements, and
Caldera must also disclose, in pro-forma statements to Caldera's financial
statements, the impact those options would have upon Caldera's reported earnings
were the value of those options at the time of grant treated as compensation
expense. Whether or not granted at a discount, the number of outstanding options
may be a factor in determining Caldera's earnings per share on a fully-diluted
basis.

     SAR or Tandem SAR grants will result in compensation expense to Caldera's
earnings. While an SAR is outstanding, the ultimate amount of compensation
inherent in the right is indeterminate. Accounting Principles Board Opinion No.
25 and FASB Interpretation No. 28, Accounting for Stock Appreciation Rights and
Other Variable Stock Option or Award Plans, require interim calculations of the
amount of compensation inherent in the SAR (variable plan accounting). Under
variable plan accounting, compensation expense can fluctuate significantly from
period to period based upon the fluctuations in the fair market value of the
underlying securities. The measurement of the expense in the financial
statements is made at the end of each reporting period based on the increase in
the fair market value since the date

                                       154
<PAGE>   167

of grant or award multiplied by the total number of shares or rights
outstanding, regardless of exercisable status of the rights. Such expense will
generally be recognized by Caldera over the period that the SAR award vests.

     Restricted stock awards are accounted for in a manner similar to the
granting of non-qualified stock option unless the award contains some type of
performance criteria. Compensation cost is generally measured under restricted
stock plans as the difference between the grant price of the restricted stock
and the fair market value of the unrestricted stock at the grant date. This cost
is recognized ratably over the period that ends when all risks of forfeiture
have passed. Restricted stock may be forfeited (or repurchased by the employer
at the employee's original purchase price) if the employee terminates prior to
the lapsing of restrictions. When restricted stock is forfeited, compensation
cost previously recognized is reversed. Any unrecognized compensation is treated
as part of the purchased treasury stock. To the extent the compensation
originally measured exceeds the market value of the treasury stock acquired, the
excess is charged to paid-in capital.

     If restricted stock awards combine performance criteria, measurement of the
ultimate compensation to be recognized occurs at the date the performance
criteria are met. This type of award is classified as a variable plan and
interim estimates of compensation are required based on a combination of the
then-fair market value of the stock as of the end of the reporting period and
the extent or degree of compliance with the performance criteria.

     Grants of shares of phantom stock are accounted for similar to SAR grants
as discussed above. Bonuses of stock are recorded as compensation at the fair
market value of the granted shares at the date of the bonus.

     Statement of Financial Accounting Standards No. 123, Accounting for
Stock-based Compensation, requires that all equity instruments transferred to
non-employees in exchange for goods and services be measured at fair value and
recorded as expense in the financial statements. As a result, an option to
purchase common stock at an exercise price equal to the fair market value on the
date of the grant to a non-employee consultant would require Caldera to record
compensation based on the fair value of the security as calculated by a
valuation methodology such as the Black-Scholes option pricing model; whereas,
the same option granted at the current fair market value to an employee does not
require the recording of such compensation in the financial statements. As a
result, the Company may incur non-cash charges related to the value of stock
awards should it grant them to non-employee consultants or contractors.

     Should one or more optionees be granted stock appreciation rights which
have no conditions upon exercisability other than a service or employment
requirement, then such rights will result in compensation expense to Caldera's
earnings.

STOCKHOLDER APPROVAL

     The affirmative vote of a majority of the outstanding voting shares of
Caldera present or represented and entitled to vote at the special meeting is
required for approval of the amendments to the 1999 Plan. Should such
stockholder approval not be obtained, then the 2,300,000 share increase to the
share reserve will not be implemented, and any stock options granted on the
basis of the 2,300,000 share increase to the 1999 Plan will immediately
terminate without becoming exercisable for the shares of common stock subject to
those options, and no additional options will be granted on the basis of such
share increase. The automatic annual share increase feature pursuant to which
the number of shares available for issuance under the 1999 Plan will
automatically increase on November 1 of each calendar year by an amount equal to
3% of the total number of shares outstanding on the previous October 31st will
also not be implemented should such stockholder approval not be obtained. In
addition, the director formula awards program, pursuant to which directors are
automatically granted options to purchase common stock at periodic intervals,
will not become part of the 1999 Plan if stock approval is not obtained. The
1999 Plan will, however, continue to remain in effect, and incentive award
grants may continue to be made pursuant to

                                       155
<PAGE>   168

the provisions of the 1999 Plan in effect prior to the amendments summarized in
this Proposal No. Two, until the available reserve of common stock as last
approved by the stockholders has been issued pursuant to incentive award grants
made under the 1999 Plan.

RECOMMENDATION OF THE BOARD OF DIRECTORS

     THE BOARD OF DIRECTORS RECOMMENDS THAT THE STOCKHOLDERS VOTE FOR THE
AMENDMENTS TO THE 1999 PLAN.

   PROPOSAL THREE: APPROVAL OF AMENDMENTS TO THE EMPLOYEE STOCK PURCHASE PLAN

     Caldera's stockholders are being asked to approve an amendment to Caldera's
2000 Employee Stock Purchase Plan (the "Purchase Plan") which will increase the
maximum number of shares of Common Stock authorized for issuance over the term
of the Purchase Plan by an additional 1.5 million shares to 2.0 million shares.

     The purpose of the amendment is to ensure that Caldera or if the
combination is consummated, New Caldera will continue to have a sufficient
reserve of Common Stock available under the Purchase Plan to provide eligible
employees of Caldera (or New Caldera) and its participating affiliates with the
opportunity to acquire a proprietary interest in Caldera (or New Caldera)
through participation in a payroll-deduction based employee stock purchase plan
under Section 423 of the Internal Revenue Code immediately after the
combination.

     The Purchase Plan was originally adopted by the Board of Directors in
February 15, 2000 and approved by the Company's stockholders on March 1, 2000.
The Purchase Plan became effective on March 20, 2000 in connection with the
initial public offering of the Company's Common Stock.

     The following is a summary of the principal features of the Purchase Plan,
as amended. The summary, however, does not purport to be a complete description
of all the provisions of the Purchase Plan. Any stockholder who wishes to obtain
a copy of the actual plan document may do so by written request to the Company's
Chief Financial Officer at the Company's executive offices in Orem, Utah.

ADMINISTRATION

     The Purchase Plan is currently administered by the Compensation Committee
of the Board. Such committee, as Plan Administrator, has full authority to adopt
administrative rules and procedures and to interpret the provisions of the
Purchase Plan. All costs and expenses incurred in plan administration are paid
by the Company without charge to participants.

SECURITIES SUBJECT TO THE PURCHASE PLAN

     Two million shares of Common Stock have been reserved for issuance over the
ten (10)-year term of the Purchase Plan. Such share reserve includes the 1.5
million-share increase for which stockholder approval is sought under this
Proposal No. Three. In addition, the share reserve will increase automatically
on the first trading day of January each calendar year beginning with the
calendar year 2001 by an amount equal to one percent (1%) of the total number of
shares of Common Stock outstanding on the last trading day of December of the
immediately preceding calendar year, but in no event will any such annual
increase exceed 750,000 shares. The shares may be made available from authorized
but unissued shares of the Company's Common Stock or from shares of Common Stock
repurchased by the Company, including shares repurchased on the open market.

     As of September 1, 2000, no shares of Common Stock had been issued under
the Purchase Plan, and 2,000,000 shares were available for future issuance,
assuming approval of this Proposal No. Three.

OFFERING PERIODS AND PURCHASE RIGHTS

     Shares of Common Stock will be offered under the Purchase Plan through a
series of successive offering periods, each with a maximum duration of
twenty-four (24) months. The first offering period began on March 20, 2000, in
connection with the initial public offering of the Common Stock, and will end on
the last business day in April 2002. The next offering period will begin on the
first business day in May 2002 and will end on the last business day of April
2004. Subsequent offering periods will begin as designated by the Plan
Administrator.

     At the time the participant joins the offering period, he or she will be
granted a purchase right to acquire shares of Common Stock at semi-annual
intervals over the remainder of that offering period. The

                                       157
<PAGE>   170

purchase dates will occur on the last business day in October and April each
year, and all payroll deductions collected from the participant for the period
ending with each such semi-annual purchase date will automatically be applied to
the purchase of Common Stock.

     Should the fair market value per share of Common Stock on any purchase date
within the twenty-four (24) month offering period be less than the fair market
value per share of Common Stock on the start date of that offering period, then
that offering period will terminate immediately after the purchase of shares of
Common Stock on such purchase date. A new offering period will commence on the
next business day following that purchase date, and all participants in the
terminated offering period will be automatically enrolled in that new offering
period. The new offering period will have a duration of twenty-four (24) months,
unless a shorter duration is established by the Plan Administrator within five
(5) business days following the start date of that offering period,

ELIGIBILITY AND PARTICIPATION

     Any individual who is employed on a basis under which he or she is expected
to work for more than 20 hours per week for more than five (5) months per
calendar year in the employ of the Company or any participating parent or
subsidiary corporation (including any corporation which subsequently becomes
such at any time during the term of the Purchase Plan) will be eligible to
participate in the Purchase Plan.

     An individual who is an eligible employee on the start date of any offering
period may join that offering period at that time or on any subsequent
semi-annual entry date (the first business day in May or November each year)
within that offering period. An individual who first becomes an eligible
employee after such start date may join the offering period on any semi-annual
entry date within that offering period on which he or she is an eligible
employee.

     As of September 1, 2000, the Company estimates that approximately 211
employees, including 6 executive officers, were eligible to participate in the
Purchase Plan.

PURCHASE PRICE

     The purchase price of the Common Stock acquired on each semi-annual
purchase date will be equal to 85% of the lower of (i) the fair market value per
share of Common Stock on the participant's entry date into the offering period
or (ii) the fair market value on the semi-annual purchase date.

     The fair market value of the Common Stock on any relevant date under the
Purchase Plan will be deemed to be equal to the closing selling price per share
on such date on the Nasdaq National Market. However, the fair market value of
the Common Stock on the start date of the initial offering period was deemed to
be equal to the $14.00 price per share at which the Common Stock was sold in the
initial public offering. On September 1, 2000, the closing selling price per
share of Common Stock on the Nasdaq National Market was $8.50 per share.

PAYROLL DEDUCTIONS AND STOCK PURCHASES

     Each participant may authorize periodic payroll deductions in any multiple
of 1% (up to a maximum of 10%) of his or her cash earnings each offering period.
Cash earnings include the participant's regular base salary plus all overtime
payments, bonuses, profit-sharing distributions and other incentive-type
payments. The accumulated payroll deductions of each participant will
automatically be applied on each semi-annual purchase date (the last business
day in October and April of each year) to the purchase of whole shares of Common
Stock at the purchase price in effect for the participant for that purchase
date.

                                       158
<PAGE>   171

SPECIAL LIMITATIONS

     The Purchase Plan imposes certain limitations upon a participant's right to
acquire Common Stock, including the following:

     - Purchase rights may not be granted to any individual who owns stock
       (including stock purchasable under any outstanding purchase rights)
       possessing 5% or more of the total combined voting power or value of all
       classes of stock of the Company or any of its affiliates.

     - Purchase rights granted to a participant may not permit such individual
       to purchase more than $25,000 worth of Common Stock (valued at the time
       each purchase right is granted) for each calendar year those purchase
       rights are outstanding at any time.

     - No participant may purchase more than 750 shares of Common Stock on any
       semi-annual purchase date.

     - The aggregate shares of Common Stock purchased on any semi-annual
       purchase date may not exceed 125,000 shares.

     The Plan Administrator will have the discretionary authority, exercisable
prior to the start of any offering period, to increase or decrease the
limitations to be in effect for the number of shares purchasable per participant
and in total by all participants on each purchase date within that offering
period.

TERMINATION OF PURCHASE RIGHTS

     The participant may withdraw from the Purchase Plan at any time, and his or
her accumulated payroll deductions will, at the participant's election, either
be refunded immediately or applied to the purchase of Common Stock on the next
semi-annual purchase date.

     The participant's purchase right will immediately terminate upon his or her
cessation of employment or loss of eligible employee status. Any payroll
deductions which the participant may have made for the semi-annual period in
which such cessation of employment or loss of eligibility occurs will be
refunded and will not be applied to the purchase of Common Stock.

STOCKHOLDER RIGHTS

     No participant will have any stockholder rights with respect to the shares
covered by his or her purchase rights until the shares are actually purchased on
the participant's behalf. No adjustment will be made for dividends,
distributions or other rights for which the record date is prior to the date of
such purchase.

ASSIGNABILITY

     No purchase rights will be assignable or transferable by the participant,
and the purchase rights will be exercisable only by the participant.

CHANGES IN CAPITALIZATION

     In the event that any change is made to the Company's outstanding Common
Stock (whether by reason of any recapitalization, stock dividend, stock split,
exchange or combination of shares or other change in corporate structure
effected without the Company's receipt of consideration), appropriate
adjustments will be made to (i) the class and maximum number of securities
issuable over the term of the Purchase Plan, (ii) the class and maximum number
of securities by which the share reserve is to increase automatically each year,
(iii) the class and maximum number of securities purchasable in total by all
participants on any one purchase date, (iv) the class and maximum number of
securities purchasable per participant on any one semi-annual purchase date and
(v) the class and number of securities and the price per share in effect under
each outstanding purchase right.

                                       159
<PAGE>   172

CHANGE IN CONTROL

     In the event the Company is acquired by merger or asset sale, all
outstanding purchase rights will automatically be exercised immediately prior to
the effective date of such acquisition. The purchase price will be equal to 85%
of the lower of (i) the fair market value per share of Common Stock on the
participant's entry date into the offering period in which such acquisition
occurs or (ii) the fair market value per share of Common Stock immediately prior
to the effective date of such acquisition. The limitation on the maximum number
of shares purchasable in total by all participants on any one purchase date will
not be in effect for the purchase date attributable to such change in control.

SHARE PRO-RATION

     Should the total number of shares of Common Stock to be purchased pursuant
to outstanding purchase rights on any particular date exceed the number of
shares at the time available for issuance under the Purchase Plan, then the Plan
Administrator will make a pro-rata allocation of the available shares on a
uniform and nondiscriminatory basis, and the payroll deductions of each
participant, to the extent in excess of the aggregate purchase price payable for
the Common Stock allocated to such individual, will be refunded.

AMENDMENT AND TERMINATION

     The Purchase Plan will terminate upon the earliest of (i) the last business
day in April 2010, (ii) the date on which all shares available for issuance
thereunder are sold pursuant to exercised purchase rights or (iii) the date on
which all purchase rights are exercised in connection with a change in control
of the Company.

     The Board may at any time alter, suspend or discontinue the Purchase Plan.
However, the Board may not, without stockholder approval, (i) increase the
number of shares issuable under the Purchase Plan or the maximum number of
shares purchasable per participant on any one semi-annual purchase date, except
in connection with certain changes in the Company's capital structure, (ii)
alter the purchase price formula so as to reduce the purchase price or (iii)
modify the requirements for eligibility to participate in the Purchase Plan.

FEDERAL TAX CONSEQUENCES

     The Purchase Plan is intended to be an "employee stock purchase plan"
within the meaning of Section 423 of the Internal Revenue Code. Under a plan
which so qualifies, no taxable income will be recognized by a participant, and
no deductions will be allowable to the Company, upon either the grant or the
exercise of the purchase rights. Taxable income will not be recognized until
there is a sale or other disposition of the shares acquired under the Purchase
Plan or in the event the participant should die while still owning the purchased
shares.

     If the participant sells or otherwise disposes of the purchased shares
within two (2) years after his or her entry date into the offering period in
which such shares were acquired or within one (1) year after the semi-annual
purchase date on which those shares were actually acquired, then the participant
will recognize ordinary income in the year of sale or disposition equal to the
amount by which the fair market value of the shares on the purchase date
exceeded the purchase price paid for those shares, and the Company will be
entitled to an income tax deduction, for the taxable year in which such
disposition occurs, equal in amount to such excess.

     If the participant sells or disposes of the purchased shares more than two
(2) years after his or her entry date into the offering period in which the
shares were acquired and more than one (1) year after the semi-annual purchase
date of those shares, then the participant will recognize ordinary income in the
year of sale or disposition equal to the lower of (i) the amount by which the
fair market value of the shares on the sale or disposition date exceeded the
purchase price paid for those shares or (ii) fifteen percent (15%) of the fair
market value of the shares on the participant's entry date into that offering
period. Any

                                       160
<PAGE>   173

additional gain upon the disposition will be taxed as a long-term capital gain.
The Company will not be entitled to an income tax deduction with respect to such
disposition.

     If the participant still owns the purchased shares at the time of death,
his or her estate will recognize ordinary income in the year of death equal to
the lower of (i) the amount by which the fair market value of the shares on the
date of death exceeds the purchase price or (ii) fifteen percent (15%) of the
fair market value of the shares on his or her entry date into the offering
period in which those shares were acquired.

ACCOUNTING TREATMENT

     The issuance of Common Stock under the Purchase Plan will not result in a
direct compensation expense chargeable against the Company's reported earnings.
However, Caldera must disclose, in pro-forma statements to the Company's
financial statements, the impact the purchase rights granted under the Purchase
Plan would have upon the Company's reported earnings were the fair value of
those purchase rights treated as compensation expense.

NEW PLAN BENEFITS

     No purchase rights have been granted, and no shares of Common Stock have
been issued, under the Purchase Plan.

STOCKHOLDER APPROVAL

     The affirmative vote of a majority of the outstanding voting shares of
Caldera present or represented and entitled to vote at the 2000 Annual Meeting
is required for approval of the 1.5 million-share increase to the Purchase Plan.
Should such stockholder approval not be obtained, then the 1.5 million-share
increase will not be implemented, and any purchase rights granted on the basis
of the 1.5 million-share increase to the Purchase Plan will immediately
terminate. No additional purchase rights will be granted on the basis of such
share increase, and the Purchase Plan will terminate once the existing share
reserve has been issued.

RECOMMENDATION OF THE BOARD OF DIRECTORS

     The Board of Directors believes that the amendment to the Purchase Plan is
necessary in order to continue to provide equity incentives to attract and
retain the services of high quality employees including through acquisitions.
FOR THIS REASON, THE BOARD OF DIRECTORS RECOMMENDS THAT THE STOCKHOLDERS VOTE
FOR THE AMENDMENT TO THE PURCHASE PLAN.

                                       161
<PAGE>   174

                     PROPOSAL FOUR: AMENDMENTS TO CALDERA'S
                          CERTIFICATE OF INCORPORATION

     The present capital structure of Caldera authorizes 75,000,000 shares of
common stock and 25,000,000 shares of preferred stock each having a par value of
$0.001 per share. The board of directors believes this capital structure is
inadequate for the present and future needs of Caldera. Therefore, the board of
directors has unanimously approved the amendment and restatement of Caldera's
Restated Certificate of Incorporation to increase the authorized number of
shares of common stock from 75,000,000 shares to 175,000,000 shares. The board
believes this capital structure more appropriately reflects the present and
future needs of Caldera and recommends such amendment and restatement to
Caldera's stockholders for adoption. The undesignated preferred stock may be
issued from time to time in one or more series with such rights, preferences and
privileges as may be determined by the board of directors. On September 1, 2000,
39,036,847 shares of common stock were outstanding and no shares of preferred
stock were outstanding.

PURPOSE OF AUTHORIZING ADDITIONAL COMMON STOCK

     Authorizing an additional 100,000,000 shares of common stock would give the
board of directors the express authority, without further action of the
stockholders, to issue such common stock from time to time as the board of
directors deems necessary. The board of directors believes it is necessary to
have the ability to issue such additional shares of common stock for general
corporate purposes. Potential users of the additional authorized shares may
include acquisition transactions, equity financings, stock dividends or
distributions, issuance of options pursuant to Caldera's 1999 Stock Incentive
Plan and issuances of common stock pursuant to Caldera's Employee Stock Purchase
Plan without further action by the stockholders, unless such action were
specifically required by applicable law or rules of any stock exchange on which
Caldera's securities may then be listed.

     The proposed increase in the authorized number of shares of common stock
could have a number of effects on Caldera's stockholders depending upon the
exact nature and circumstances of any actual issuances of authorized but
unissued shares. The increase could have an anti-takeover effect, in that
additional shares could be issued (within the limits imposed by applicable law)
in one or more transactions that could make a change in control or takeover of
Caldera more difficult. For example, additional shares could be issued by
Caldera so as to dilute the stock ownership or voting rights of persons seeking
to obtain control of Caldera. Similarly, the issuance of additional shares of
certain persons allied with Caldera's management could have the effect of making
it more difficult to remove Caldera's current management by diluting the stock
ownership or voting rights of persons seeking to cause such removal. In
addition, an issuance of additional shares by Caldera could have an effect on
the potential realizable value of a stockholders' investment. In the absence of
a proportionate increase in Caldera's earnings and book value, an increase in
the aggregate number of outstanding shares of Caldera caused by the issuance of
the additional shares would dilute the earnings per share and book value per
share of all outstanding shares of Caldera's common stock. If such factors were
reflected in the price per share of common stock, the potential realizable value
of a stockholder's investment could be adversely affected. The common stock
carries no preemptive rights to purchase additional shares.

     The proposed amendment and restate of Caldera's Certificate of
Incorporation was approved by unanimous written consent of the directors of the
Company in August 2000.

STOCKHOLDER APPROVAL

     The affirmative vote of a majority of Caldera's outstanding voting shares
is required for approval of the amendment and restatement of Caldera's
Certificate of Incorporation authorizing 100,000,000 additional shares of common
stock.

RECOMMENDATION OF THE BOARD OF DIRECTORS

     The board of directors recommends a vote FOR the amendment and restatement
of Caldera's Certificate of Incorporation authorizing 100,000,000 additional
shares of common stock.

              OTHER ACTION TO BE TAKEN AT THE SCO SPECIAL MEETING

Change in SCO's Corporate Name to Tarantella, Inc.

     At the SCO special meeting, SCO's shareholders will also be asked to
approve a proposed amendment to SCO's articles of incorporation, that if
approved, will change SCO's corporate name to "Tarantella, Inc." SCO seeks this
change in the corporate name because, as a result of the combination
contemplated by the reorganization agreement, New Caldera will acquire the SCO
brand and logo. Though SCO will retain usage rights in the SCO brand and logo,
SCO's focus will shift to the Tarantella business.

     Tarantella is software that allows centralized deployment and management of
server-based applications. Tarantella is designed for information technology
professionals who need to provide users with instant access to applications and
services, and provides centralized management of application access.

     The SCO board of directors believes that the proposed name change is in its
best interest because the proposed new corporate name reflects SCO's principal
line of business after the completion of the combination. The SCO board of
directors believes that, notwithstanding the goodwill associated with the SCO
name, it is necessary to change the corporate name in order to connect the image
of the company among the investment community and among our customers and
potential customers to our products and services and in order to avoid confusion
with SCO's historical business.

     SCO's board of directors has unanimously adopted a resolution declaring it
advisable to amend the company's articles of incorporation to change the
corporate name. SCO's board of directors further directed that the proposed name
change be submitted for consideration by shareholders at the special meeting. As
amended, Article I of the articles of incorporation would read in its entirety
as follows:

                                   "Article I

                The name of the corporation is Tarantella, Inc."

     In the event the proposed name change is approved by shareholders, SCO will
thereafter file a certificate of amendment to its articles of incorporation with
the Secretary of State of the State of California, amending Article I, which
will become effective on the date such filing is accepted by the Secretary of
State. The SCO board of directors, however, reserves the right not to file the
certificate of amendment even if the proposed name change is approved by the
shareholders in the event the shareholders do not approve and adopt the
reorganization agreement or the reorganization agreement is otherwise
terminated.

          UNAUDITED PRO FORMA CONDENSED COMBINED FINANCIAL INFORMATION

                INTRODUCTION TO PRO FORMA FINANCIAL INFORMATION

     On August 1, 2000 and as amended on September 13, 2000, Caldera Systems,
Inc. ("Caldera"), Caldera, Inc. ("New Caldera"), and The Santa Cruz Operation,
Inc. ("SCO") entered into an Agreement and Plan of Reorganization (the
"Reorganization Agreement"). As a result of the transactions proposed by the
Reorganization Agreement (the "Reorganization"), (i) a newly formed, wholly
owned subsidiary of New Caldera will be merged with and into Caldera, with
Caldera being the surviving corporation, and all outstanding Caldera securities
will be converted, on a share for share basis, into New Caldera securities
having identical rights, preferences and privileges, with New Caldera assuming
any and all outstanding options and other rights to purchase shares of capital
stock of Caldera (with all such New Caldera securities issued to former Caldera
security holders initially representing a fully diluted equity interest of
approximately 71.4% in New Caldera); (ii) SCO and certain of its subsidiaries
will contribute to New Caldera, all of the capital stock held of certain
contributed companies as well as certain assets of SCO collectively representing
the server and professional services groups of SCO, in consideration for the
issuance by New Caldera to SCO of shares of common stock of New Caldera, $0.001
par value ("New Caldera Common Stock"); (iii) New Caldera will assume or
replace, as elected by the option holders, all options to acquire common stock
of SCO held by SCO employees (other than certain officers of SCO) hired or
retained by Caldera and such options will be converted into options to purchase
New Caldera Common Stock on a two-for-one basis representing in the aggregate a
fully diluted equity interest of approximately 3.1% in New Caldera; and (iv) SCO
will receive shares of New Caldera Common Stock representing in the aggregate a
fully diluted equity interest of approximately 25.5% in New Caldera and
$7,000,000 in cash. In conjunction with the Reorganization Agreement, The Canopy
Group, Inc., a major stockholder of Caldera has agreed to loan $18 million to
SCO and Caldera has agreed to loan $7 million to SCO. The assets of SCO will
secure each of these loans.

     The unaudited pro forma condensed combined balance sheet of New Caldera
gives effect to the Reorganization as if it had been completed as of July 31,
2000. The unaudited pro forma condensed combined balance sheet of New Caldera
combines the historical balance sheet of Caldera as of July 31, 2000 and the
historical balance sheet of the server and professional services groups as of
June 30, 2000. The unaudited pro forma condensed combined statements of
operations of New Caldera give effect to the Reorganization as if it had been
completed at November 1, 1998. The unaudited pro forma condensed combined
statement of operations of New Caldera for the nine months ended July 31, 2000
combines the historical statement of operations of Caldera for the nine months
ended July 31, 2000 and the historical statement of operations of the server and
professional services groups for the nine months ended June 30, 2000. The
unaudited pro forma condensed combined statement of operations for the year
ended October 31, 1999 combines the historical statement of operations of
Caldera for the year ended October 31, 1999 and the historical statement of
operations for the server and professional services groups for the year ended
September 30, 1999.

     The acquisition of the server and professional services groups will be
accounted for using the purchase method of accounting. Under this method, the
total purchase price, including fees and expenses, will be allocated to the
tangible and identifiable intangible assets acquired and the liabilities assumed
based upon their respective fair values as of the effective date of the
acquisition. New Caldera has estimated the fair value of the tangible assets
acquired and liabilities assumed. An independent third party appraisal company
has conducted a preliminary valuation of the server and professional services
group's intangible assets. The remaining purchase price over the tangible and
identifiable intangible assets will be allocated to goodwill. Since the
acquisition has not yet been completed, the actual consideration cannot yet be
determined. For the purpose of the pro forma combined financial information
included herein, the number of shares of New Caldera common stock and options to
purchase shares of common stock to be issued in the acquisition has been
estimated based upon the number of Caldera's common shares and options to
purchase common shares outstanding at July 31, 2000. The actual number of New
Caldera common shares to be issued will be based on the actual shares and
options outstanding as of the completion of the

                                       P-1
<PAGE>   178

Reorganization. Additionally, the actual allocation of the amount of such
consideration may differ from that reflected in these unaudited pro forma
condensed combined financial statements after final valuations and other
procedures have been completed.

     The fair value of the in-process research and development will be recorded
as an expense in the period in which the acquisition is completed. The valuation
of the in-process research and development was determined using the income
approach method, which includes an analysis of the markets, cash flows and risks
associated with achieving such cash flows. The amount allocated to the
in-process research and development represents the estimated purchased
in-process technology for projects that had not yet reached technological
feasibility and have no alternative future use. Based on preliminary
assessments, the value of these projects was determined by estimating the costs
to develop the purchased in-process technology into commercially viable
products; estimating the resulting net cash flows from the sale of the products
resulting from completion of the projects reduced by the portion of the revenue
attributable to core technology; and discounting the net cash flows back to
their present value.

     The unaudited pro forma condensed consolidated balance sheet of SCO gives
effect to the reorganization as if it had been completed as of June 30, 2000.
The unaudited pro forma condensed consolidated statements of operations of SCO
for the year ended September 30, 1999 and the nine months ended June 30, 2000
give effect to the reorganization discussed as if it had occurred on October 1,
1998. SCO will treat this transaction as a disposal of its server and
professional services groups and record a gain upon completion of the
transaction. On an ongoing basis it will account for its investment in New
Caldera using the equity method of accounting.

     The unaudited pro forma condensed combined financial statements included in
this joint proxy statement/prospectus are presented for illustrative purposes
only. Such information is not necessarily indicative of the operating results or
financial position that would have taken place if the Reorganization had been
completed at the beginning of the earliest period presented, nor is it
indicative of the results that may be expected for future periods. The pro forma
adjustments are based upon information and assumptions available at the time of
the filing of this joint proxy statement/prospectus. The pro forma information
should be read in conjunction with the accompanying notes thereto and with the
historical financial statements and related notes of Caldera, as well as the
historical financial statements and related notes of SCO and the server and
professional services groups included elsewhere in this joint proxy
statement/prospectus.

                         COMBINED FINANCIAL STATEMENTS

1. BASIS OF PRESENTATION

     The pro forma condensed combined financial statements included herein have
been prepared pursuant to the rules and regulations of the Securities and
Exchange Commission. Certain information and certain footnote disclosures
normally included in financial statements prepared in accordance with accounting
principles generally accepted in the United States have been condensed or
omitted pursuant to such rules and regulations; however, management believes
that the disclosures are adequate to make the information presented not
misleading.

2. REORGANIZATION

     For purposes of computing the estimated purchase price, the value of the
common stock was determined by taking the closing price of Caldera's common
stock as quoted on NASDAQ for the two days before, the day of and the two days
following the signing of the Reorganization Agreement. The estimated
consideration to be exchanged in the Reorganization is based on preliminary
estimates and is subject to certain adjustments. The following table sets forth
the estimated consideration to be exchanged for the SCO server and professional
services groups, including estimated direct expenses to be paid in connection
with the Reorganization (dollars in thousands, except per share amounts).

<TABLE>
<S>                                                           <C>

     common stock to be issued in exchange for outstanding

</TABLE>

     For purposes of computing the estimated fair value of the New Caldera stock
options to be issued to SCO employees, the Black-Scholes option pricing model
was used with the following assumptions: expected life of 2 1/2 years, risk free
interest rate of 6 percent, expected dividend yield of 0 percent, and volatility
of 145 percent. The following table sets forth the allocation of the
consideration to the tangible and intangible assets acquired and liabilities
assumed.

     The value allocated to in-process research and development will be charged
to expense upon consummation of the acquisition. The write-off was necessary
because the acquired in-process research and development had not yet reached
technological feasibility and had no future alternative uses. Management
believes that the acquired in-process research and development will be
successfully developed; however, these technologies may not achieve commercial
viability.

     The valuation of the in-process research and development included, but was
not limited to, an analysis by independent appraisers of the market for the
acquired products and technologies, the completion costs for the projects, the
expected cash flows attributed to the projects and the risks associated with
achieving such cash flows. The assumptions used by the appraisers in valuing the
in-process research and development were based upon assumptions management
believes to be reasonable, but which are inherently uncertain and unpredictable.
For these reasons, actual results may vary from the estimated results.

     New Caldera will not acquire certain assets nor assume certain liabilities
pursuant to the Reorganization Agreement. The excluded assets and liabilities
included in the June 30, 2000 historical carved-out balance sheet of the server
and professional services groups were as follows:

  groups not assumed by New Caldera.........................  $(12,717)

</TABLE>

     For purposes of the presentation in the pro forma condensed combined
balance sheet, the non-acquired assets and non-assumed liabilities have been
included to more fairly reflect the ongoing financial position of New Caldera.

3. PRO FORMA COMBINED NET LOSS PER COMMON SHARE

     The pro forma combined net loss per common share is based on the weighted
average number of common shares of Caldera and the shares to be issued to SCO
for the year ended October 31, 1999 and the nine-month period ended July 31,
2000. The dilutive effect of common share equivalents has not been included
since the pro forma combined condensed statements of operations reflect net
losses for the year ended October 31, 1999 and the nine months ended July 31,
2000.

     The pro forma combined basic and diluted net loss per common share was
determined as follows (in thousands):

4. SALES REPRESENTATIVE AND SUPPORT AGREEMENT

     In connection with the Reorganization, New Caldera and SCO will enter into
a Sales Representative and Support Agreement (the "Sales and Support
Agreement"). Under the terms of the Sales and Support Agreement, New Caldera
will act as the sales representative for the SCO OpenServer products. All rights

related to the SCO OpenServer products and related technology will be retained
by SCO. New Caldera has agreed to sell the OpenServer products in accordance
with prices, discounts, warranties, and other terms to be established by SCO.
SCO will retain inventory and credit risk related to OpenServer products as well
as rights to reject any purchase order, approve or disprove any credit extended
outside of SCO guidelines, accept the return of products and make allowances.
SCO will pay to New Caldera commission fees of 11% of net revenue from
OpenServer licenses and 25% of net revenue from sales of media kits, as defined.
The commission fees to be received by New Caldera will be accounted for as
services revenue.

     For purposes of the SCO server and professional services groups historical
financial statements, revenue from the OpenServer products and related expenses
have been excluded. Accordingly, pro forma adjustments are required to reflect
New Caldera's commission fees and related expenses pursuant to the Sales and
Support Agreement (see Note 6).

     In addition to the commission fee, SCO will reimburse New Caldera for
expenses relating to marketing activities in an amount equal to the lesser of
actual marketing expenses or 15% of net revenue from OpenServer products. The
marketing reimbursements will be reflected as an offset to the actual expenses
incurred and accordingly no pro forma adjustment is necessary.

     The Sales and Support Agreement will automatically terminate after a period
of five years. New Caldera may terminate the Sales and Support Agreement after
three years by paying SCO an amount equal to two times the OpenServer product
revenue during the preceding 12-month period.

5. OPENSERVER RESEARCH AND DEVELOPMENT AGREEMENT

     In connection with the Reorganization, New Caldera and SCO will enter into
a Research and Development Agreement (the "Development Agreement"). Under the
terms of the Development Agreement, New Caldera will provide independent
contracting services for maintaining, testing and supporting the SCO OpenServer
products as directed by SCO. Contract services revenue under the Development
Agreement will be based on all direct and indirect expenses incurred by New
Caldera plus ten percent. Direct and indirect expenses will consist primarily of
payroll and related costs, facilities and equipment.

     For purposes of the SCO server and professional services group's historical
financial statements, the estimated research and development expenses related to
the OpenServer Products have been excluded. Accordingly, pro forma adjustments
are required to reflect New Caldera's contract engineering revenue and related
costs pursuant to the Development Agreement (see Note 6).

6. PRO FORMA ADJUSTMENTS

     The pro forma condensed combined financial statements give effect to the
following pro forma adjustments in connection with the Reorganization:

PRO FORMA CONDENSED COMBINED BALANCE SHEET

          (a) To reflect the estimated consideration to be exchanged as
     summarized in Note 2 including the issuance of common stock and options to
     purchase common stock amounting to $125,315,000 and the $7,000,000 cash
     payment.

          (b) To reflect the $3,350,000 of estimated direct expenses related to
     the Reorganization including legal, accounting, printing and investment
     banking fees.

          (c) To reflect the identifiable intangible assets and goodwill
     amounting to $140,574,000 as summarized in Note 2.

                  COMBINED FINANCIAL STATEMENTS -- (CONTINUED)

          (d) To reflect an accrual of $500,000 for estimated shut-down of
     non-essential facilities and related costs. Certain facilities have been
     identified by management of New Caldera that will be closed following
     consummation of the Reorganization. The accrual for shut-down and related
     costs has not been included in the accompanying pro forma condensed
     combined statements of operations as it represents a non-recurring charge
     directly related to the acquisition.

          (e) To record a deferred tax liability related to book-to-tax basis
     differences of acquired identifiable intangible assets using an estimated
     effective tax rate of 37.5 percent.

          (f) To reflect the impact of the write-off of acquired in-process
     research and development. The in-process research and development charge
     has not been included in the accompanying pro forma condensed combined
     statements of operations as it represents a non-recurring charge directly
     related to the acquisition.

          (g) To reflect the net liabilities of the SCO server and professional
     services groups of $12,717,000 (See Note 2) which will not be assumed by
     New Caldera pursuant to the Reorganization Agreement. The net liabilities
     not assumed consist primarily of accounts payable and accrued liabilities,
     offset by non-acquired accounts receivable.

          (h) To record the elimination of the divisional deficit of the SCO
     server and professional services groups.

PRO FORMA CONDENSED COMBINED STATEMENTS OF OPERATIONS

          (i) To reflect the commission fees to be received by New Caldera in
     accordance with the terms of the Sales and Support Agreement discussed in
     Note 4. The commission fees represent 11 percent of the historical net
     revenue from OpenServer licenses and 25% of net revenue from sales of media
     kits. SCO's net revenue from sales of OpenServer products were not included
     in the SCO server and professional services groups carved-out historical
     financial statements. SCO's historical revenue from its OpenServer products
     decreased during the nine months ended June 30, 2000 as compared to the
     same period of the prior year. Sales of OpenServer products may continue to
     decrease in future periods due to technological and other competitive
     factors. Accordingly, the pro forma commission fees revenue included in the
     accompanying pro forma financial statements may not be indicative of future
     results.

          (j) To reflect the contract research and development services revenue
     in accordance with the Development Agreement discussed in Note 5. Pursuant
     to the Development Agreement, New Caldera will be paid for development and
     support services related to SCO's retained OpenServer products based on
     direct and indirect costs plus 10 percent. The amount of engineering and
     support revenues was estimated based on SCO's historical research and
     development expenses incurred related to the OpenServer products, which
     were excluded from the SCO server and professional services group's
     carved-out historical financial statements. The pro forma research and
     development services revenue based on SCO's historical results may not be
     indicative of future research and development services revenue to be
     generated by New Caldera due to the potential decreases in sales of
     OpenServer products as discussed above in (i).

          (k) To reflect the estimated costs of research and development
     activities related to the OpenServer line of products reflected in (j).

          (l) In connection with the Reorganization, SCO has agreed to pay three
     executive officers who will become executive officers of New Caldera cash
     bonuses amounting to $1,073,000 in aggregate if they have not voluntarily
     terminated their employment with SCO or New Caldera for one year following
     closing of the Reorganization. Accordingly, the payments to be made by SCO
     have been

     reflected in the accompanying pro forma condensed combined statement of
     operations for the year ended October 31, 1999 as additional operating
     expenses.

          (m) To reflect the estimated expenses associated with generating the
     OpenServer commission fees revenue reflected in (i) at an assumed
     break-even margin.

          (n) To reflect the amortization of intangible assets and goodwill
     related to the acquisition calculated using the straight-line method and
     estimated useful lives of five years for the distribution/reseller channel,
     existing technology, OpenServer distributor agreement and goodwill and
     three years for the assembled workforce and trade name and trademarks.

          (o) To reflect the additional shares of common stock to be issued as
     discussed in Note 3.

                         THE SANTA CRUZ OPERATION, INC.

                     NOTES TO UNAUDITED PRO FORMA CONDENSED
                              FINANCIAL STATEMENTS

1. BASIS OF PRESENTATION

     The unaudited pro forma condensed financial statements included herein have
been prepared pursuant to the rules and regulations of the Securities and
Exchange Commission. Certain information and certain footnote disclosures
normally included in financial statements prepared in accordance with accounting
principles generally accepted in the United States have been condensed or
omitted pursuant to such rules and regulations; however, we believe that the
disclosures are adequate to make the information presented not misleading.

     On August 1, 2000 Caldera Systems Inc. ("Caldera"), Caldera Holding, Inc.
("New Caldera") and The Santa Cruz Operation, Inc. ("SCO") entered into an
Agreement and Plan of Reorganization (the "Reorganization"). Under the terms of
the Reorganization, SCO will contribute the capital stock of certain companies
as well as certain assets collectively representing the server and professional
services group. In exchange for this SCO will receive an approximate 25.5% fully
diluted equity interest (with the employees of the server and professional
services groups receiving options equivalent to an additional 3.1% of New
Caldera's fully diluted equity) in New Caldera together with $7,000,000 in cash.
SCO will treat this transaction as a disposal of its server and professional
services groups and record a gain upon completion of the transaction. On an
ongoing basis it will account for its investment in New Caldera using the equity
method of accounting. (See Note 2 for a further explanation of the effects).

     The unaudited pro forma condensed balance sheet of SCO gives effect to the
reorganization as if it had been completed as of June 30, 2000. The unaudited
pro forma condensed statements of operations of SCO for the year ended September
30, 1999 and the nine months ended June 30, 2000 give effect to the
reorganization discussed as if it had occurred on October 1, 1998.

2. REORGANIZATION

     The accompanying pro forma statements reflect the contribution of SCO's
server and professional services groups to New Caldera in exchange for the
issuance of 16,327,323 shares of New Caldera common stock, representing an
approximate 29.5% interest in New Caldera on an outstanding shares basis and an
approximate 25.5% interest on a fully diluted basis, plus $7 million in cash.
The number of shares to be received in the exchange is based on the
capitalization of SCO and Caldera as of July 31, 2000 and the gain calculation
assumes a fair value for New Caldera Stock of $6.87. The actual number of shares
received by SCO will be based on the capitalization of SCO and New Caldera on
the closing date of the transaction and as a result the actual gain recorded may
be materially different to that detailed below.

     As SCO will retain a 29.5% interest in New Caldera, including the server
and professional services group, after the Reorganization it will not recognize
a gain on 100% of the contribution of the server and professional services
group. SCO will record a gain calculated at 70.5% times the fair value of the
New Caldera stock received less 70.5% of the SCO's basis in the assets of the
server and professional services groups plus net cash consideration received in
the transaction as follow (dollars in thousands except per share amounts:

                     NOTES TO UNAUDITED PRO FORMA CONDENSED
                      FINANCIAL STATEMENTS -- (CONTINUED)

     Subsequent to the completion of the Reorganization SCO's operating results
will include 29.5% of the operating results of New Caldera, adjusted to amortize
the difference between the recorded amount of SCO's investment and the amount of
its underlying equity in the net assets of New Caldera. The amount of this
difference is estimated as follows: (dollars in thousands)

<TABLE>
<S>                                                           <C>
Adjusted fair value of New Caldera common stock.............  $ 79,079
Portion of investment in New Caldera with no step up in
  basis.....................................................     1,797
Bonus paid to New Caldera employees (Note 3)................     1,073
SCO's share of New Caldera pro forma net assets after
  completion of the reorganization..........................   (59,793)
                                                              --------
Estimated difference........................................  $ 22,156
                                                              ========
</TABLE>

     This estimated difference will be amortized over its estimated useful life
of five years and will result in a charge to SCO's statement of operations of
approximately $1,107,000 per quarter.

     The pro-forma unaudited condensed statements of operations include both a
charge for this amortization element discussed above and 29.5% of New Caldera's
pro forma operating results minus the effects of the Sales Representative and
Support agreement discussed at note 4 to these unaudited pro-forma condensed
financial statements.

     The above calculation is an estimate based on the gain assumptions
discussed above and using New Caldera's unaudited pro-forma combined condensed
balance sheet as of July 31, 2000. The actual amount of difference recorded will
be calculated based on the balance sheet of Caldera after closing of the
transaction and could be materially different to the amount above.

3. BENEFITS TO BE PROVIDED TO SCO EXECUTIVES

     In connection with the Reorganization, the Board of Directors has elected
to provide certain change of control benefits to some of its executive officers.
These include:

          (a) the full acceleration of vesting provisions on all options issued
     and outstanding prior to August 1, 2000 held by seven executive officers.

          (b) an extension of the option term on options granted to three
     individuals who will become executive officers of New Caldera.

          (c) an extension of the option term, in the case of options held by
     those executive officers staying with SCO, if such individuals employment
     is involuntarily terminated or terminated by mutual consent such that
     options held by those individuals will expire in no event sooner than
     January 31, 2002; and

          (d) a cash payment on the earlier of (a) one year, provided that such
     executive officer has not voluntarily terminated his employment with SCO or
     New Caldera, as the case may be, or (b) immediately upon an involuntary
     termination or a termination by mutual consent, equal to; that individual's
     current annual salary plus 100% of his target bonus.

     SCO expects to record a charge of approximately $2,379,000 in respect of
the option modifications, a further charge of $2,120,000 to be recorded to
operations over one year in connection with the expected cash payments to be
made to the executives remaining with SCO and an increase of its investment in
New Caldera of approximately $1,073,000 in respect of payments to be made to the
three executives who will be transferred to New Caldera as part of the
Reorganization.

                     NOTES TO UNAUDITED PRO FORMA CONDENSED
                      FINANCIAL STATEMENTS -- (CONTINUED)

     The accompanying unaudited pro forma condensed financial statements include
adjustments for the expenses to be recorded in respect of the option amendment
and the bonus payments which are expected to be made by SCO.

4. SALES REPRESENTATIVE AND SUPPORT AGREEMENT

     In connection with the Reorganization, New Caldera and SCO will enter into
a Sales Representative and Support Agreement (the "Sales and Support
Agreement"). Under the terms of the Sales and Support Agreement, New Caldera
will act as the sales representative for the SCO OpenServer products. All rights
related to the SCO OpenServer products and related technology will be retained
by SCO. New Caldera has agreed to sell the OpenServer products in accordance
with prices, discounts, warranties, and other terms to be established by SCO.
SCO will retain inventory risk related to OpenServer products as well as rights
to reject any purchase order, approve or disprove any credit extended outside of
SCO guidelines, accept the return of products and make allowances. Depending
upon the class of revenue, SCO will pay to Caldera a commission fee of 11% or
25% of net revenue, reduced by a provision for bad debts, relating to the sale
of OpenServer products. The commission fees to be paid by SCO will be accounted
for as sales and marketing expenses.

     In addition to the commission fee, SCO will reimburse New Caldera for
expenses relating to marketing activities in an amount equal to the lesser of
actual marketing expenses or 15% of revenue from OpenServer products.

     The Sales and Support Agreement will automatically terminate after a period
of five years. New Caldera may terminate the Sales and Support Agreement after
three years by paying SCO an amount equal to two times the OpenServer product
revenue during the preceding 12-month period.

5. OPENSERVER RESEARCH AND DEVELOPMENT AGREEMENT

     In connection with the Reorganization, New Caldera and SCO will enter into
a Research and Development Agreement (the "Development Agreement"). Under the
terms of the Development Agreement, New Caldera will provide independent
contracting services for maintaining, testing and supporting the SCO OpenServer
products as directed by SCO. Contract services revenue under the Development
Agreement will be based on all direct and indirect expenses incurred by New
Caldera plus ten percent. Direct and indirect expenses will consist primarily of
payroll and related costs, facilities and equipment.

     For purposes of the SCO server and professional services group's historical
financial statements, the estimated research and development expenses related to
the OpenServer Products have been excluded. Accordingly, pro forma adjustments
are required to reflect payments to New Caldera for contract engineering costs
pursuant to the Development Agreement (see Note 6).

6. PRO FORMA ADJUSTMENTS

     The unaudited pro forma condensed combined financial statements give effect
to the following pro forma adjustments in connection with the Reorganization:

          (a) To reflect the gain and related taxation payable on the sale of
     the assets and liabilities of the server and professional services groups
     and the recognition of the pro rata gain in connection with this
     transaction (see Note 2). Taxation payable on the gain has been estimated
     at 40%.

          (b) To reflect the assets and liabilities of the server and
     professional services groups which will not be assumed pursuant to the
     reorganization.

                      FINANCIAL STATEMENTS -- (CONTINUED)

          (c) To reflect the commission fees to be received by New Caldera in
     accordance with the terms of the Sales and Support Agreement discussed in
     Note 4. SCO's net revenue from sales of OpenServer products were not
     included in the SCO server and professional services groups' historical
     financial statements.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To Caldera Systems, Inc.:

     We have audited the accompanying consolidated balance sheets of Caldera
Systems, Inc. (a Delaware corporation), the carved-out portion of Caldera, Inc.
(a Utah corporation) and their subsidiary as of October 31, 1998 and 1999, and
the related consolidated statements of operations and comprehensive loss,
stockholders' equity and cash flows for each of the three years in the period
ended October 31, 1999. 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 auditing standards generally
accepted in the United States. Those standards require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements
are free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements. An
audit also includes assessing the accounting principles used and significant
estimates made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a reasonable basis
for our opinion.

     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Caldera
Systems, Inc., the carved-out portion of Caldera, Inc. and their subsidiary as
of October 31, 1998 and 1999, and the results of their operations and their cash
flows for each of the three years in the period ended October 31, 1999 in
conformity with accounting principles generally accepted in the United States.

                     CALDERA SYSTEMS, INC., THE CARVED-OUT
                 PORTION OF CALDERA, INC. AND THEIR SUBSIDIARY

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(1) ORGANIZATION AND DESCRIPTION OF BUSINESS

     Caldera Systems, Inc. ("Caldera"), incorporated as a Utah corporation on
August 21, 1998, and reincorporated as a Delaware corporation on March 6, 2000,
began operations in 1994 as Caldera, Inc. (the "Predecessor"). The Predecessor
developed and marketed Linux operating system software and related products.

     In July 1996, through an asset purchase, the Predecessor acquired an
additional business line which was not engaged in developing and marketing Linux
software and related products. The Predecessor subsequently made the strategic
determination to separate its two business lines into separate entities and,
under an asset purchase agreement, dated as of September 1, 1998, as amended,
sold the assets relating to its business of developing and marketing Linux
software and related products to Caldera for $19,928,848. This amount was based
upon the amount of funding that had been received by the Predecessor related to
the Linux software business. The purchase price was paid as follows: a cash
payment of $14,963,826 (8% interest bearing demand note) in fiscal year 1999,
the assumption of $36,174 of liabilities, and the transfer of a note receivable
due from the Predecessor in the amount of $4,928,848 (see below).

     Upon incorporation, Caldera agreed to issue 16,000,000 shares of common
stock to The Canopy Group ("Canopy"), the majority stockholder of the
Predecessor, in exchange for $20,928,848. Of this amount, $16,000,000 was paid
in cash ($519,000 in fiscal year 1998 and $15,481,000 -- non-interest
bearing -- in fiscal year 1999) and Canopy transferred to Caldera a note
receivable from the Predecessor of $4,928,848.

     Since Canopy was the majority stockholder of the Predecessor and the sole
stockholder of Caldera, this transaction has been accounted for as a
reorganization of entities under common control with the assets and liabilities
reflected at carry-over basis in a manner similar to pooling of interests. The
accompanying consolidated financial statements include the carved-out operations
of the Predecessor related to the Linux business through September 1, 1998, the
date of the reorganization. The acquired assets and liabilities had a net book
value of $768,693. The excess of the purchase price of $19,928,848 over the net
book value of the assets acquired of $768,693 was charged to equity.

     The revenues of the carved-out operations of the Predecessor reflect actual
revenues derived from Linux software sales and the expenses of the carved-out
operations reflect actual expenses associated with the Linux business and an
allocated portion of common expenses. The allocated common expenses consist
primarily of rent, depreciation, interest and personnel benefits. Rent,
depreciation and personnel benefits were allocated based upon headcount.
Interest was allocated based upon borrowings related to the carved-out
operations of the Predecessor. Management believes that the allocation methods
used are reasonable.

     Prior to the reorganization, the net losses of the Predecessor were funded
through loans and equity contributions from Canopy. The funding applicable to
the carved-out operations has been reflected as a component of Caldera, Inc.'s
Equity in Carved-out Operations included in the accompanying consolidated
statements of stockholders' equity. This funding has been offset by the
accumulated losses applicable to the carved-out operations.

     In connection with the reorganization, Caldera acquired a wholly-owned
subsidiary in Germany, Caldera Deutschland, GmbH ("Caldera GmbH"), that performs
research and development activities. Collectively, Caldera, the carved-out
operations of the Predecessor and Caldera GmbH are referred to as the "Company."

     The Company develops, markets and supports Linux operating system software
products and related services. The Company's strategy is to provide commercial
products and services that enable the development, deployment and management of
Linux-based specialized servers and Internet devices that

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

extend the e-Business infrastructure. The Company sells and distributes its
software and related products indirectly through distributors, value added
resellers ("VARs"), original equipment manufacturers ("OEMs"), and system
integrators and directly to end-user customers. These sales occur throughout the
United States and in certain international locations.

     The Company is subject to certain risks including the uncertainty of market
acceptance and demand for Linux related products and services, competition from
larger, more established companies, short product life cycles, the Company's
ability to develop and bring to market new products on a timely basis,
dependence on key employees, the ability to attract and retain additional
qualified personnel and the ability to obtain adequate financing to support
growth.

(2) SIGNIFICANT ACCOUNTING POLICIES

UNAUDITED INTERIM FINANCIAL STATEMENTS

     The unaudited interim financial statements as of July 31, 2000 and for the
nine months ended July 31, 1999 and 2000 have been prepared on the same basis as
the audited financial statements and, in the opinion of management, reflect all
normal recurring adjustments necessary to present fairly the financial
information set forth therein in accordance with generally accepted accounting
principles. All financial statement disclosures related to the interim financial
statements are unaudited.

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 these estimates.

FAIR VALUE OF FINANCIAL INSTRUMENTS

     The carrying amounts reported in the accompanying consolidated financial
statements for cash, accounts receivable, other receivables and accounts payable
approximate fair values because of the immediate or short-term maturities of
these financial instruments. The carrying amounts of the Company's debt
obligations approximate fair value based on current interest rates. The fair
values of available-for-sale securities are determined using quoted market
prices for these securities.

PRINCIPLES OF CONSOLIDATION

     The consolidated financial statements include the accounts of the
carved-out operations of the Predecessor prior to Caldera's incorporation,
Caldera, and their wholly-owned subsidiary after elimination of intercompany
accounts and transactions.

FOREIGN CURRENCY TRANSLATION

     For purposes of consolidating the Caldera GmbH operations, the Company has
determined the functional currency for the Caldera GmbH operations to be the
German Mark. Accordingly, translation gains and losses are included as a
component of comprehensive loss.

                                       F-9

                 PORTION OF CALDERA, INC. AND THEIR SUBSIDIARY

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

CASH AND CASH EQUIVALENTS

     For purposes of the statements of cash flows, the Company considers all
highly liquid debt instruments purchased with maturities of three or fewer
months to be cash equivalents. Cash equivalents primarily consist of investments
in money market mutual funds, commercial paper or other short-term debt
instruments.

AVAILABLE-FOR-SALE SECURITIES

     Available-for-sale securities include investments in debt and equity
securities with lives in excess of three months. These investments are recorded
at fair market value, based on quoted market prices and unrealized gains and
losses are recorded as a component of comprehensive loss. Realized gains and
losses, which are calculated based on the specific identification method, are
recorded in operations as incurred.

INVENTORIES

     Inventories consist primarily of completed products and raw materials.
Inventories are stated at the lower of cost (using the first-in, first-out
method) or market value. As of October 31, 1998 and 1999 and July 31, 2000,
inventories consisted of raw materials of approximately $40,400, $79,400 and
$231,900 (unaudited), respectively, and finished goods of approximately $9,300,
$90,000 and $85,300 (unaudited), respectively.

     Provisions, when required, are made to reduce excess and obsolete
inventories to their estimated net realizable values. Due to competitive
pressures and technological innovation, it is possible that estimates of the net
realizable value could change in the near term.

PROPERTY AND EQUIPMENT

     Property and equipment are stated at cost, less accumulated depreciation
and amortization. Computer equipment and furniture and fixtures are depreciated
using the straight-line method over the estimated useful life of the asset,
typically three to five years. Leasehold improvements are amortized using the
straight-line method over the shorter of the estimated useful life of the
improvement or the remaining term of the applicable lease.

     Expenditures for repairs and maintenance are charged to expense when
incurred. Expenditures for major renewals and betterments that extend the useful
lives of existing equipment are capitalized and depreciated. On retirement or
disposition of property and equipment, the cost and related accumulated
depreciation are removed from the accounts and any resulting gain or loss is
recognized in the statement of operations.

CAPITALIZED SOFTWARE COSTS

     In accordance with Financial Accounting Standards Board ("FASB") Statement
of Financial Accounting Standards No. 86, "Accounting for the Costs of Computer
Software to be Sold, Leased or Otherwise Marketed" ("SFAS 86"), development
costs incurred in the research and development of new software products to be
sold, leased or otherwise marketed are expensed as incurred until technological
feasibility in the form of a working model has been established. Internally
generated capitalizable software development costs have not been material for
the years ended October 31, 1997, 1998 and 1999 and the nine months ended July
31, 2000. The Company has charged its software development costs to research and
development expense in the accompanying consolidated statements of operations.

                 PORTION OF CALDERA, INC. AND THEIR SUBSIDIARY

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

OTHER ASSETS

     Other assets consist of purchased technology that is to be used in the
development of the Company's web-based products and is being amortized using the
straight-line method over a period of two years.

IMPAIRMENT OF LONG-LIVED ASSETS

     The Company reviews its long-lived assets, including intangibles, for
impairment when events or changes in circumstances indicate that the book value
of an asset may not be recoverable. The Company evaluates, at each balance sheet
date, whether events and circumstances have occurred which indicate possible
impairment. The Company uses an estimate of future undiscounted net cash flows
of the related asset or group of assets over the remaining life in measuring
whether the assets are recoverable. As of October 31, 1999 and July 31, 2000,
the Company does not consider any of its long-lived assets to be impaired.

REVENUE RECOGNITION

     The Company generates revenue from software and related products sold
indirectly through distributors and solutions providers and directly to
end-users. The Company also generates services revenue from training royalties
and tuition fees, consulting fees, and customer support fees. During fiscal 1997
and fiscal 1998, all of the Company's revenues were derived from software
offerings and related products such as shipments of incomplete box units or
documentation materials.

     Revenue from the sale of software is recognized upon delivery of the
product when persuasive evidence of an arrangement exists, the price is fixed or
determinable and collection is probable. All sales into the distribution channel
or to OEMs and VARs require a binding purchase order. Sales to resellers for
which payment is considered to be substantially contingent on the reseller's
success in distributing individual units of the product or sales to resellers
with which the Company does not have historical experience are accounted for as
consignments and the revenue is recognized once sell-through verification has
been received and payments from customers become due. Direct sales to end users
are evidenced by concurrent payment for the product via credit card and are
governed by a license agreement. Generally, the only multiple element
arrangement of the Company's initial software sales is certain telephone and
e-mail technical support services the Company provides at no additional charge.
These services do not include product update or upgrade rights. After the
initial support period, customers can elect to enter into separate support
agreements. The cost of providing the initial support services are not
significant; accordingly, the Company accrues the estimated costs of providing
the services at the time of revenue recognition. Revenues from the extended
support agreements are deferred and recognized over the period of the contract
or as the services are provided.

     If other significant post-delivery vendor obligations exist or if a product
is subject to customer acceptance, revenues are deferred until no significant
obligations remain or acceptance has occurred. To date, the Company has not
shipped any software and related products subject to acceptance terms or subject
to other post-delivery vendor obligations. Additionally, the Company has not
recognized revenue on any contracts with customers that may include customer
cancellation or termination clauses that indicate a demonstration period or
otherwise incomplete transaction.

     The Company also offers its customers consulting, training and other
services separate from the software sale. The services are not integral to the
functionality of the software and are available from other vendors. Services
revenue is recognized as the services are performed.

                     CALDERA SYSTEMS, INC., THE CARVED-OUT
                 PORTION OF CALDERA, INC. AND THEIR SUBSIDIARY

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

     In October 1997, the American Institute of Certified Public Accountants
("AICPA") issued Statement of Position No. 97-2, "Software Revenue Recognition"
("SOP 97-2"), which the Company has adopted for transactions entered into for
the years ended October 31, 1998 and 1999. The adoption of SOP 97-2 did not have
a significant impact on the Company's revenue recognition practices, or its
results of operations, financial position or liquidity.

     In December 1998, the AICPA issued Statement of Position No. 98-9,
"Modification of SOP No. 97-2, Software Revenue Recognition, With Respect to
Certain Transactions" ("SOP 98-9"). SOP 98-9 amends SOP 97-2 to require
recognition of revenue using a "residual method" in certain circumstances. The
Company adopted SOP 98-9 for transactions entered into for the years ended
October 31, 1998 and 1999. The adoption of this statement did not have a
significant effect on the Company's revenue recognition practices or its results
of operations, financial position or liquidity.

     Sales to certain distributors are subject to agreements allowing for rights
of return and price protection. Allowances for estimated future returns, price
protection, stock rotations, as well as anticipated end-user customer rebates
and other customer incentives, are provided at the time of sale based on the
Company's policies and historical experience. At October 31, 1998 and 1999 and
July 31, 2000, allowances for returns, price protection and stock rotations
totaled approximately $54,000, $169,000 and $484,100 (unaudited), respectively,
and are reflected as a current liability in the accompanying consolidated
balance sheets.

ROYALTY COSTS

     Royalties paid by the Company on applications licensed from third parties
that are incorporated into the software products sold by the Company are
expensed as cost of revenue on a per unit basis as software products are sold.
Royalties paid in advance of product sales are included in prepaid expenses and
recorded as cost of revenue when the related products are sold.

     During the years ended October 31, 1996 and 1997, the Company entered into
royalty agreements with a supplier pursuant to which the Company prepaid
royalties of approximately $2,055,000. During fiscal year 1998, the Company
asserted that the supplier breached the terms of the royalty agreements and
management determined that the remaining prepaid royalties, in the amount of
$1,381,700, were impaired and accordingly were written off and classified as
part of cost of revenue in the accompanying consolidated statement of operations
for the year ended October 31, 1998. Management determined the asset was
impaired because its value was tied to the intellectual property value of the
licenses the Company had purchased. The vendor breached the terms of the
contract in management's view, when it open sourced some of the related
software. When the vendor decided to open source the software, the license the
Company had purchased had no value in relation to that software. Additionally,
the Company discontinued the development of a product related to the licensed
software resulting in the complete impairment of the prepaid asset. Management
further determined that any attempt to pursue legal action against the supplier
would be costly and uncertain given the resources required to pursue such an
action and the uncertainties related to interpreting the provisions of the
royalty agreements.

SALES AND MARKETING EXPENSES

     Sales and marketing expenses consist of the following: advertising, channel
promotions, marketing development funds, promotional activities, public
relations, trade shows and the salaries, commissions and related expenses of all
personnel involved in the sales process. The Company expenses the cost of
advertising the first time the advertising takes place. Advertising expenses
totaled approximately

                 PORTION OF CALDERA, INC. AND THEIR SUBSIDIARY

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

$2,515,800, $967,700 and $1,228,600 for the years ended October 31, 1997, 1998
and 1999, respectively, and $1,002,000 (unaudited) for the nine-month period
ended July 31, 2000.

     The Company has agreements with certain retailers whereby the Company
issues a credit for certain marketing development activities initiated by the
retailer that directly relate to the promotion of the Company's products. As of
October 31, 1998 and 1999 and July 31, 2000, the Company recorded an accrual of
$0, $172,900 and $76,100 (unaudited), respectively, for these costs.

INCOME TAXES

     The Company recognizes a liability or asset for the deferred tax
consequences of all temporary differences between the tax bases of assets and
liabilities and their reported amounts in the consolidated financial statements
that will result in taxable or deductible amounts in future years when the
reported amounts of the assets and liabilities are recovered or settled. These
deferred tax assets or liabilities are measured using the enacted tax rates that
will be in effect when the differences are expected to reverse. Deferred tax
assets are reviewed periodically for recoverability and valuation allowances are
provided as necessary.

CONCENTRATION OF CREDIT RISK AND SIGNIFICANT CUSTOMERS

     The Company offers credit terms on the sale of its software products to
certain customers. The Company performs ongoing credit evaluations of its
customers' financial condition and requires no collateral from its customers.
The Company maintains an allowance for uncollectable accounts receivable based
upon the expected collectibility of all accounts receivable. As of October 31,
1998, three distributors accounted for approximately 67 percent of the gross
accounts receivable balance. As of October 31, 1999, three distributors
accounted for approximately 71 percent of the gross accounts receivable balance.
As of October 31, 1998 and 1999 and July 31, 2000, the allowance for bad debts
was $15,000, $90,000 and $302,500 (unaudited), respectively.

RECENT ACCOUNTING PRONOUNCEMENTS

     In June 1998, the FASB issued Statement of Financial Accounting Standards
No. 133, "Accounting for Derivative Instruments and Hedging Activities" ("SFAS
133"). SFAS 133 establishes new accounting and reporting standards for companies
to report information about derivative instruments, including certain derivative
instruments embedded in other contracts (collectively referred to as
derivatives), and for hedging activities. This statement is effective for
financial statements issued for all fiscal quarters of fiscal years beginning
after June 15, 2000. The Company does not expect this statement to have a
material impact on the Company's results of operations, financial position or
liquidity.

     In December 1999, the Securities and Exchange Commission ("SEC") staff
issued Staff Accounting Bulletin No. 101 ("SAB 101"), "Revenue Recognition in
Financial Statements." This pronouncement summarizes certain of the SEC staff's
views in applying generally accepted accounting principles to selected revenue
recognition issues. The Company is required to adopt SAB 101 during the first
quarter of fiscal year 2001. Although management is currently evaluating the
impact, if any, of SAB 101, management does not presently believe it will have a
material impact on the Company's results of operations, financial position or
liquidity.

     In March 2000, the FASB issued Interpretation No. 44 "Accounting for
Certain Transactions involving Stock Compensation, an interpretation of
Accounting Principles Board Opinion No. 25 ("APB 25")." This interpretation
clarifies the definition of employee for purposes of applying APB 25, the
criteria for determining whether a plan qualifies as a noncompensatory plan, the
accounting consequence of various

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

modifications to the terms of a previously fixed stock option or award, and the
accounting for an exchange of stock compensation awards in a business
combination. This interpretation is effective July 1, 2000, but certain
conclusions in this interpretation cover specific events that occur after either
December 15, 1998, or January 12, 2000. To the extent that this interpretation
covers events occurring during the period after December 15, 1998, or January
12, 2000, but before the effective date of July 1, 2000, the effects of applying
this interpretation are recognized on a prospective basis from July 1, 2000.
Although management is currently evaluating the impact, if any, of this
interpretation, management does not presently believe it will have a material
impact on the Company's results of operations, financial position or liquidity.

COMPREHENSIVE INCOME (LOSS)

     In fiscal 1998, the Company adopted Statement of Financial Accounting
Standards No. 130, "Reporting Comprehensive Income" ("SFAS 130"). SFAS 130
establishes standards for reporting comprehensive income (loss) and its
components in financial statements and unrealized gains on short-term
investments. Comprehensive income (loss) consists of net loss, foreign currency
translation adjustments and unrealized gain (loss) on available for sale
securities and is presented in the accompanying consolidated statements of
operations and comprehensive loss. The adoption of SFAS 130 had no impact on
total stockholders' equity at the time of adoption.

NET LOSS PER COMMON SHARE

     The Company computes net loss per share in accordance with Statement of
Financial Accounting Standards No. 128, "Earnings Per Share" ("SFAS 128"), and
SEC Staff Accounting Bulletin No. 98 ("SAB 98"). Under the provisions of SFAS
128 and SAB 98, basic net loss per common share ("Basic EPS") is computed by
dividing net loss available to common stockholders by the weighted average
number of common shares outstanding. Diluted net loss per common share ("Diluted
EPS") is computed by dividing net loss by the sum of the weighted average number
of common shares and the dilutive potential common share equivalents then
outstanding. Potential common share equivalents consist of shares issuable upon
the exercise of stock options and shares issuable upon the conversion of Series
A and Series B convertible preferred stock. For the year ended October 31, 1999
and the nine months ended July 31, 2000, there were 2,964,240 and 7,659,524
(unaudited) common share equivalents, respectively, that were not included in
the computation of diluted net loss per common share as their effect would have
been anti-dilutive, thereby decreasing the net loss per common share. For the
years ended October 31, 1997 and 1998, the 16,000,000 shares of common stock
issued in the initial capitalization of Caldera were treated as outstanding for
the entire fiscal year.

(3) INITIAL PUBLIC OFFERING

     On March 20, 2000, the Company completed the sale of an aggregate of 5.0
million shares of common stock at a price of $14.00 per share in a firm
commitment underwritten initial public offering. The offering was affected
pursuant to a Registration Statement on Form S-1 (Registration No. 333-94351),
which was declared effective on March 20, 2000 by the United States Securities
and Exchange Commission. On April 17, 2000, the underwriters exercised their
over allotment option for an additional 750,000 shares of common stock, at
$14.00 per share,

     We received approximately $80.5 million in proceeds from this offering, of
which approximately $5.6 million was paid to the underwriters and approximately
$3.0 million was paid for direct offering expenses.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

(4) OTHER RECEIVABLES

     Other receivables as of October 31, 1999 consisted of amounts due from two
strategic partners that participated in a marketing program with the Company.
The amounts received by the Company from the strategic partners have been
applied against actual expenses incurred and have reduced the related sales and
marketing expense of the Company. Aside from the collection of the short-term
receivable balances, there are no other future commitments or consideration
related to these arrangements.

(5) BORROWINGS FROM CANOPY

SECURED CONVERTIBLE PROMISSORY NOTE PAYABLE

     In connection with the incorporation of Caldera, Caldera and Canopy entered
into a Secured Convertible Promissory Note Agreement (the "Note Agreement")
pursuant to which the Company could borrow up to $2,000,000, or such other
greater amount as determined necessary, to fund ongoing operations. Interest
accrued on borrowings under the Note Agreement at the prime rate, less one-half
percent compounded annually, which was 7.25 percent. Borrowings under the Note
Agreement were convertible to shares of Caldera's common stock at $1.00 per
share, which was deemed to be the estimated fair market value of Caldera's
common stock on September 1, 1998. Under the Note Agreement, the Company
borrowed $4,819,000 during the year ended October 31, 1999. Additionally,
accrued interest of $454,974 was incurred by the Company related to borrowings
under the Note Agreement and the amount payable to the Predecessor for the
assets acquired in the reorganization (see Note 1). On August 19, 1999, the
principal borrowings and accrued interest were converted into 5,273,974 shares
of common stock and the Note Agreement was cancelled.

SECURED PROMISSORY NOTE WITH CANOPY (UNAUDITED)

     On December 29, 1999, Caldera entered into a Secured Promissory Note
Agreement ("the Note") with Canopy under which the Company borrowed $300,000.
Borrowings under the Note bore interest at 9.5 percent per annum and were repaid
in full during January 2000.

(6) STOCKHOLDERS' EQUITY

REINCORPORATION AS A DELAWARE CORPORATION

     On March 6, 2000, Caldera reincorporated in Delaware. The reincorporation
into Delaware was effected by way of a merger with a newly-formed Delaware
subsidiary, and the associated issuance of one share of common stock of the
subsidiary for each share of common stock of the Company held by the
stockholders of record. Additionally, stockholders of record of Series A and
Series B of the Company received shares of Series A and Series B preferred stock
of the subsidiary. All share and per share amounts in the accompanying
consolidated financial statements have been adjusted to give effect to the
reincorporation.

STOCK SPLIT

     On December 29, 1998, Caldera's board of directors approved a two-for-one
stock split for holders of common stock. This stock split has been retroactively
reflected in the accompanying consolidated financial statements for all periods
presented.

PREFERRED STOCK

     On December 30, 1999, the stockholders approved articles of amendment to
the Company's articles of incorporation. The amended articles of incorporation
authorized the Company to issue 25,000,000 shares of no par value preferred
stock and 75,000,000 shares of no par value common stock. The Company's board of
directors is authorized, without stockholder approval, to designate and
determine the preferences, limitations and relative rights granted to or imposed
upon each share of preferred stock which are not fixed by the amended articles
of incorporation. The amended articles of incorporation have designated
6,596,146 shares as Series A Convertible Preferred Stock ("Series A") and
5,000,000 shares as Series B Convertible Preferred Stock ("Series B").

     The Series A and B shares have initial stated values per share of $4.03 and
$6.00, respectively, and rank on parity with each other and prior to any other
class or series of capital stock of the Company with respect to dividend rights,
rights upon liquidation, winding up or dissolution, and redemption rights. The
Series A and B shares are entitled to receive, when, as and if declared by the
board of directors, cumulative and accruing preferential dividends at eight
percent per annum, compounded annually, based on the stated value per share;
provided, however, solely for dividend purposes the Series A stated value per
share is deemed to be $6.00. Any holder of Series A or B shares may convert all
or any shares of Series A or B into common shares and each share of Series A or
B automatically converts into common shares immediately prior to the closing of
a firm commitment underwritten public offering of at least $25,000,000, as
defined. Each Series A and B share initially converts into one share of common
stock. The conversion ratio is adjusted for stock splits and like events. The
holders of Series A and B shares are entitled to vote on all matters submitted
to the stockholders of the Company, including the election of directors,
together with the holders of common stock voting together as a single class.
Each share of Series A and B is entitled to one vote for each share of common
stock that would be issuable upon conversion of such share.

     In the event of any voluntary or involuntary liquidation, dissolution or
winding up of the Company, each holder of Series A and B then outstanding shall
be entitled to receive, on a pari passu basis, out of the assets available for
distribution to stockholders an amount equal to the greater of (i) the sum of
(1) the respective stated value per share plus (2) an amount equal to all unpaid
accruing dividends (whether or not declared) plus (3) any other dividends
declared but unpaid, and (ii) the amount that such holder of Series A or B
shares would hold had all shares of Series A and B been converted to common
immediately prior to the liquidation, dissolution, or winding up.

CONVERSION OF COMMON SHARES INTO SERIES A SHARES

     Prior to the offering of Series B shares discussed below, on December 30,
1999 the Company entered into a Conversion Agreement with its two major
stockholders, Canopy and MTI Technology Corporation ("MTI"). These stockholders
held 99 percent of the outstanding shares of the Company's common stock at
December 30, 1999. Pursuant to the Conversion Agreement, the Company converted
6,596,146 shares of outstanding common stock held by Canopy and MTI into
6,596,146 shares of Series A.

ISSUANCE OF SERIES B CONVERTIBLE PREFERRED STOCK AND RELATED AGREEMENTS

     On December 30, 1999, the Company's board of directors authorized the
issuance of 5,000,000 shares of Series B convertible preferred stock at $6 per
share with the rights, preferences, privileges and restrictions as described
above. As of January 10, 2000, the 5,000,000 shares had been sold for net
proceeds of $29,790,674.

     Each share of Series B convertible preferred stock was immediately
convertible to one share of common stock upon issuance. During the nine months
ended July 31, 2000, the Company recorded a

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

dividend related to the Series B convertible preferred stock in the amount of
$10 million representing the value of the beneficial conversion feature. The
beneficial conversion feature was calculated based on the difference between the
conversion price of $6.00 per share and the estimated fair value of the common
stock of $8.00 per share for financial reporting purposes based on the estimated
price range for the Company's IPO. The Company's board of directors determined
that the $6.00 per share price for the Series B preferred stock represented
their estimate of the fair value of the Series B preferred stock at the time
sold and that the Series B preferred shares were not issued for other
consideration or goods and services.

     In connection with the preferred stock purchase agreements, the Company and
the investors entered into a second amended and restated investor rights
agreement (the "Rights Agreement") and a voting agreement. Pursuant to the
voting agreement, the Company and the preferred stockholders established the
composition of the Company's board of directors.

     Pursuant to the Rights Agreement, Canopy and MTI, the Series A preferred
stockholders, and the investors in the Series B preferred stock (collectively
the "Preferred Stockholders") have certain rights beginning six months following
the closing of a qualified public offering with respect to registration of the
common shares issued or issuable upon conversion of the Series A and Series B
preferred shares in compliance with the Securities Exchange Act of 1934. The
Preferred Stockholders have certain demand and piggy-back rights that require
the Company to use its best efforts to register the requested shares and/or
permit the Preferred Stockholders to include shares in certain secondary
offerings of the Company's common stock. The Company has agreed to bear all
expenses in connection with any registration, other than underwriting discounts
and commissions.

COMMON STOCK TRANSACTIONS

     Effective September 1, 1998, in connection with the initial capitalization
of Caldera, Canopy purchased 16,000,000 shares of Caldera's common stock for
$20,928,848. Of this amount, $16,000,000 was paid in cash ($519,000 in fiscal
year 1998 and $15,481,000 in fiscal year 1999) and Canopy transferred to Caldera
a note receivable from the Predecessor of $4,928,848. As of October 31, 1998,
the Company had recorded the $15,481,000 to be received from Canopy as a stock
subscription receivable and the purchase price and related accrued interest
totalling $15,163,890 as a payable to Caldera, Inc. (see Note 1).

     At the time of incorporation, Canopy agreed to continue to fund the
operations of the Company through a secured convertible promissory note (see
Note 5). The conversion terms of the secured promissory note allowed Canopy to
convert the borrowings and accrued interest into common stock at a price of
$1.00 per share, which was determined by the Company's board of directors to be
the estimated fair market value of the Company's common stock on September 1,
1998, the date of the convertible promissory note agreement. In August 1999,
Canopy elected to convert the outstanding principal borrowings and accrued
interest into 5,273,974 shares of the Company's common stock.

     In July 1999, the Company negotiated with MTI, a publicly traded company
which at the time was 50 percent owned by Canopy, to sell 5,333,333 common
shares for $6,000,000, or $1.13 per share. The Company received $3,000,000 in
cash at the time of closing and issued a note receivable for $3,000,000 that
bears interest at the prime rate plus one percent (9 1/4 percent as of October
31, 1999). This note receivable was to be received in two installments of
$1,500,000 due in January 2000 and July 2000. The Company negotiated to receive
the initial installment of $1,500,000 (unaudited) in November 1999 in exchange
for the Company agreeing to forego the interest component attached to the note
receivable. As a result of this modification, the Company did not record any
accrued interest in the consolidated balance sheet as of October 31, 1999. The
$1,500,000 received in November 1999 and the $1,500,000 received in

August 2000 have been reflected as current assets in the accompanying
consolidated balance sheets as of October 31, 1999 and July 31, 2000. In
connection with MTI's investment, the Company entered into an Investors' Rights
Agreement with MTI and Canopy pursuant to which MTI received registration rights
applicable to the stock acquired. This Investors' Rights Agreement was amended
and superceded in connection with the Conversion Agreement and the offering of
Series B preferred shares discussed above.

STOCK OPTION PLANS

     During fiscal year 1998, the Company adopted the 1998 Stock Option Plan
(the "1998 Plan") that provided for the granting of nonqualified stock options
to purchase shares of common stock. Under the 1998 Plan, the Company could grant
up to 5,000,000 options to employees, non-employee members of the board of
directors or consultants who provide services to the Company. Options granted
under the 1998 Plan are subject to expiration and vesting terms as determined by
a committee of the Company's board of directors. No options can expire more than
ten years from the date of grant. The exercise price for the options may be paid
in cash or in shares of the Company's common stock valued at fair market value
on the exercise date. The options may also be exercised through a same-day sale
program without any cash outlay by the optionee. At October 31, 1999, options to
purchase 2,035,738 shares of common stock were available for future grants under
the 1998 Plan.

     On December 1, 1999, the Company's board of directors approved the 1999
Omnibus Stock Incentive Plan (the "1999 Plan"), which is intended to serve as
the successor equity incentive program to the 1998 Plan. The 1999 Plan initially
increased the aggregate number of shares available for issuance under both plans
to 6,700,000 and designated that 700,000 shares be used as director incentives.
On March 10, 2000, the Company's board of directors authorized an additional
500,000 shares to be issued under the 1999 Plan and during July 2000 the board
of directors approved an additional 2,300,000 (unaudited) shares to be issued
under the 1999 Plan. The 1999 Plan allows for the grant of awards in the form of
incentive and non-qualified stock options, stock appreciation rights, restricted
shares, phantom stock and stock bonuses. Awards may be granted to individuals in
the Company's employ or service.

     The 1999 Plan will be administered by the compensation committee of the
board of directors. This committee will determine which eligible individuals are
to receive awards under the 1999 Plan, the type of award to be made, the time or
times when such awards are to be made, the number of shares subject to each such
award, and the vesting schedule and the other terms to be in effect for the
award.

     The exercise price for the options may be paid in cash, in shares of the
Company's common stock valued at fair market value on the exercise date or by
having the Company retain sufficient shares of common stock from shares which
would be issuable upon the exercise of the option. The option may also be
exercised through a same-day sale program without any cash outlay by the
optionee.

     Tandem stock appreciation rights may be issued under the 1999 Plan which
will provide the holders with the election to surrender their outstanding
options for a cash appreciation distribution from the Company equal to the fair
market value of the vested shares subject to the surrendered option less the
aggregate exercise price payable for such shares. In addition, the Company may
issue stand-alone stock appreciation rights which will entitle the holder to
receive a cash payment from the Company equal to the fair market value of the
vested shares subject to the right less the base price for such right.

     Phantom stock awards will entitle the holder to receive in cash the fair
market value of common stock on the vesting date.

     In the event that the Company is acquired (whether by merger or asset sale)
or there is a change in control (effected through an acquisition of 50% or more
of the Company's voting stock or by proxy contest

for the election of board members), options and stand-alone stock appreciation
rights exercisable at that time will remain exercisable until their expiration,
and options and stand-alone stock appreciation rights not exercisable at that
time will expire. Also, if the Company is acquired or experiences a change in
control, all restrictions on outstanding vested shares of restricted stock
granted under the 1999 Plan will lapse, and all outstanding, unvested shares of
such restricted stock will expire and be cancelled. Similarly, all outstanding,
unvested shares of phantom stock will expire and be cancelled.

STOCK-BASED COMPENSATION

     The Company accounts for its stock options issued to directors, officers
and employees under Accounting Principles Board Opinion No. 25 and related
interpretations ("APB 25"). Under APB 25, compensation expense is recognized if
an option's exercise price on the measurement date is below the intrinsic fair
value of the Company's common stock. During the year ended October 31, 1999, the

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

Company granted 2,460,838 stock options with exercise prices that were below the
estimated fair market value on the measurement date resulting in $3,144,230 in
deferred compensation. This deferred compensation has been recorded as a
component of stockholders' equity and will be expensed consistent with the
vesting of the underlying stock options. Amortization of deferred compensation
amounted to $409,296 for the year ended October 31, 1999. During the nine months
ended July 31, 2000, the Company has granted 4,181,613 (unaudited) additional
stock options with exercise prices ranging from $1.13 to $14.75. The granting of
these options resulted in $6,790,264 (unaudited) of additional deferred
compensation to be recognized as expense over the vesting period of the options.
Amortization of deferred compensation amounted to $4,000,751 during the nine
months ended July 31, 2000.

     Statement of Financial Accounting Standards No. 123, "Accounting for
Stock-Based Compensation" ("SFAS 123") requires pro forma information regarding
net loss as if the Company had accounted for its stock options granted under the
fair value method. The fair market value of the stock options is estimated on
the date of grant using the Black-Scholes option-pricing model with the
following assumptions for grants during the year ended October 31, 1999:
risk-free interest rate of 5.5 percent; expected dividend yield of 0 percent;
volatility of 0 percent, and expected exercise lives of five years. For purposes
of the pro forma disclosure, the estimated fair market value of the stock
options is amortized over the vesting periods of the respective stock options.

WARRANT AGREEMENT BETWEEN CANOPY AND SERIES B PREFERRED STOCKHOLDER (UNAUDITED)

     In connection with the Series B preferred stock offering, Canopy and
Egan-Managed Capital, L.P. ("EMC"), one of the investors in the Series B
preferred stock offering, entered into a letter agreement wherein Canopy agreed
to purchase the shares of Series B convertible preferred stock purchased by EMC
in the event that EMC did not receive a warrant in a satisfactory form to EMC to
purchase 416,667 shares of the Company's common stock from Canopy. On March 13,
2000, Canopy sold to EMC a warrant for $10,000 to purchase 416,667 shares of the
Company's common stock held by Canopy at $5.98 per share for a two-year period.
Upon exercise of the warrant, all proceeds will be paid to Canopy. Since the
sale of this warrant directly related to the issuance of Series B preferred
stock, the Company accounted for this transaction as if the Company had sold the
warrant to EMC with an offsetting contribution to capital. Accordingly, the
Company recorded the fair value of the warrant of $2,252,717, determined using
the Black-Scholes option-pricing model, as a beneficial conversion feature
reflected as a dividend related to the Series B preferred stock during the nine
months ended July 31, 2000. Assumptions used in the Black-Scholes option-pricing
model were the following: estimated fair value of common stock of $8.00 per
share; risk-free interest rate of 6 percent; expected dividend yield of 0

     The 2000 Employee Stock Purchase Plan was adopted by the board of directors
on February 15, 2000 and was approved by the stockholders on March 1, 2000. The
plan became effective upon the closing of the Company's initial public offering.
The plan is designed to allow eligible employees of Caldera and its
participating subsidiaries to purchase shares of Caldera common stock, at
semi-annual intervals, through periodic payroll deductions. A total of 500,000
shares of common stock has been reserved for issuance under the plan. The share
reserve will increase on the first trading day of each calendar year beginning

with the 2001 calendar year by 1% of the total number of shares of common stock
outstanding on the last day of the immediately preceding year but no such annual
increase will exceed 750,000 shares. In no event, however, may a participant
purchase more than 750 shares, nor may all participants in the aggregate
purchase more than 125,000 shares on any one semi-annual purchase date.

     The plan will have a series of successive offering periods, each with a
maximum duration of 24 months. The initial offering period began on the date of
the Company's initial public offering and will end on the last business day in
April 2002. The next offering period will begin on the first business day in May
1, 2002, and subsequent offering periods will be set by the compensation
committee. Shares will be purchased on semi-annual purchase dates (the last
business day of April and October each year) during the offering period. The
first purchase date will be October 31, 2000. Should the fair market value of
our common stock on any semi-annual purchase date be less than the fair market
value on the first day of the offering period, then the current offering period
will automatically end and a new offering period will begin, based on the lower
fair market value.

     Individuals who are eligible employees on the start date of any offering
period may enter the Plan on that start date or on any subsequent semi-annual
entry date (generally May 1 or November 1 each year). Individuals who become
eligible employees after the start date of the offering period may join the plan
on any subsequent semi-annual entry date within that period.

     A participant may contribute up to 10% of his or her cash earnings through
payroll deductions and the accumulated payroll deductions will be applied to the
purchase of shares on the participant's behalf on each semi-annual purchase date
(the last business day in April and October each year). The purchase price per
share will be 85% of the lower of the fair market value of our common stock on
the participant's entry date into the offering period or the fair market value
on the semi-annual purchase date.

     The board may at any time amend or modify the plan. The plan will terminate
no later than the last business day in April 2010.

(7) INCOME TAXES

     As described in Note l, Caldera became a separate legal entity effective
September 1, 1998. The income tax attributes associated with the carved-out
portion of Caldera, Inc. prior to September 1, 1998 remained with the
Predecessor.

     Since incorporation, Caldera has reported for income tax purposes as a
stand-alone taxable entity. For income tax purposes, the reorganization of the
Predecessor and the sale of the Linux software business to Caldera has been
treated as a taxable asset sale. Accordingly, the tax basis of the assets
received from the Predecessor is based on the $19,928,848 purchase price (see
Note 1). The reorganization did not qualify as a tax-free reorganization because
the Predecessor did not transfer substantially all of its assets to Caldera.

     The net loss before income taxes consisted of the following components for
the period from the reorganization (September 1, 1998) through October 31, 1998
and for the year ended October 31, 1999:

     The amount of and ultimate realization of the deferred income tax assets is
dependant, in part, upon the tax laws in effect, Caldera's future earnings, and
other future events, the effects of which cannot be determined. The Company has
established a valuation allowance against its deferred income tax assets.
Management believes that, based on a number of factors, the available objective
evidence creates sufficient uncertainty regarding the realizability of these
deferred income tax assets.

LITIGATION

     The Company is a party to certain legal proceedings arising in the ordinary
course of business. Management believes, after consultation with legal counsel,
that the ultimate outcome of such legal proceedings will not have a material
adverse effect on the Company's financial position, liquidity or results of
operations.

SEVERANCE AGREEMENTS (UNAUDITED)

     During July and August 2000, the Company entered into severance agreements
with certain members of management. The agreements are only in effect upon a
change of control and termination or effective termination of employment with

equal to 150 percent of the then current annual base salary and bonuses, 18
months of accelerated vesting on outstanding stock options and continuing
insurance benefits for a period up to six months. Specific provisions for Vice
Presidents include but are not limited to the following; salary and bonus
payments equal to 100% of the then current annual base salary and bonuses, 12

OPERATING LEASE AGREEMENTS

     The Company leases its corporate office facilities from the Predecessor.
The lease commenced on September 1, 1998 and expired on August 31, 2000. The
rent payment under this lease was approximately $12,100 per month and was based
on the portion of total square footage used by the Company. Rent expense under
this arrangement totaled approximately $0, $19,200 and $144,700 for the years
ended October 31, 1997, 1998 and 1999, respectively. This lease required the
Company to pay taxes, maintenance, insurance and certain other operating costs
of the leased property. The lease was renewed at substantially the same terms as
had been previously arranged

     In October 1999, the Company entered into an assignment and extension of an
existing operating lease with an unrelated lessor for research and development
space. Monthly lease payments under this arrangement were $10,000 and required
the Company to pay certain operating expenses such as maintenance, insurance and
other operating costs. The lease expired on July 31, 2000.

     On September 1, 1999, the Company entered into an operating lease
arrangement for its Caldera GmbH facility. The lease requires monthly minimum
payments of 8,750 DM (approximately $4,880 U.S. dollars based on the exchange
rate as of October 31, 1999) and expires five years from the date of
commencement. Caldera GmbH also has the option of extending the agreement for
two consecutive five-year terms. This lease requires the Company to pay taxes,
maintenance, insurance and certain other operating costs of the property.

     The Company leases warehouse space from an unrelated lessor under an
eighteen-month lease which expires in November 2000. Rent expense under the
lease is approximately $32,000 per year.

     On March 30, 2000, the Company entered into an operating lease agreement
whereby the Company agreed to lease 5,146 square feet of office space for $8,255
per month. This lease is for a term of five years and commenced on June 1, 2000.

     On April 5, 2000, the Company entered into an amended operating lease
agreement whereby the Company leases additional office space adjacent to its
corporate offices. The amendment requires additional lease payments of
approximately $34,934 per month, and the lease expires December 2002. The lease
may be terminated at an earlier date in accordance with the provisions of the
original lease agreement.

SOFTWARE LOCALIZATION AGREEMENT

     On October 1, 1999, the Company entered into an agreement with United
Systems Engineers, Inc. ("USE") to localize certain of the Company's software
products for the Japanese market. As consideration, the Company agreed to pay
$250,000 in cash or issue to the engineering firm shares of the Company's common
stock with a market value of $202,000, based on the initial public offering
price per share. On January 4, 2000, the Company and USE amended the agreement
pursuant to which the Company agreed to issue 33,667 shares of common stock to
USE for the services, of which 16,833 were to be issued immediately for services
rendered and the remaining 16,834 are to be issued upon completion of the
services. Should USE not perform under the agreement, USE will not be issued the
remaining 16,834 shares of common stock, and USE has committed to pay $100,000
to the Company. Based on the performance commitment, the date of the amended
contract has been determined to be the measurement date and the estimated fair
value of the Company's common stock on that date of $269,336, or $8 per share,
will be expensed as the services are rendered.

SOFTWARE LICENSE AGREEMENTS WITH SUN MICROSYSTEMS, INC.

     In January 2000, the Company and Sun Microsystems, Inc. ("Sun"), an
investor in the Company's Series B preferred stock, entered into certain
software license agreements. Pursuant to one of the software license agreements,
the Company agreed to pay Sun a nonrefundable payment in the amount of
$1,250,000. During the nine months ended July 31, 2000, the Company made the
required payments to Sun and recorded the payments as prepaid license fees and
marketing expense. Under the agreements, the Company has access to certain of
Sun's technologies and participates with Sun in various marketing activities.
The Company is expensing the portion of the fee allocated to the technology
ratably over the duration of the agreements and is expensing the portion of the
fee allocated to the marketing activities as the activities occur.

under a secured convertible promissory note agreement (see Note 5). In August
1999, the principal borrowings and accrued interest of $454,974 were converted
into 5,273,974 shares of common stock. The chairman of the Company's board of
directors is the president and chief executive officer and a director of Canopy.
Additionally, another director of the Company is the chairman of Canopy's board
of directors.

     The Company has entered into certain transactions with Canopy and other
entities that are majority-owned by Canopy. These transactions consist mainly of
participating in joint insurance coverage, training and testing services, and
rent. The Company believes that the terms of these related party transactions
are at least as favorable as the terms that could have been obtained from an
unaffiliated third party in similar transactions. During the years ended October
31, 1997, 1998 and 1999, transactions with these related parties were as
follows:

     As of October 31, 1999, the Company had related party payables of $48,933.
These payables are non-interest bearing and provide for settlement through cash
payments in the normal course of business.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

     As a result of an option agreement between Canopy and its chief executive
officer, who is also the chairman of the Company's board of directors, we
expensed a one-time compensation charge of approximately $372,000 (unaudited)
during the nine months ended July 31, 2000. The option agreement, which granted
options to purchase Caldera shares directly from Canopy, was subsequently
rescinded. No shares were purchased under the agreement.

LINEO, INC.

     As discussed in Note 13, in January 2000, the Company acquired an ownership
interest in Lineo, Inc. ("Lineo"), the successor entity to the operations of the
Predecessor which were not acquired by Caldera in the reorganization discussed
in Note 1. The chairman of the Company's board of directors and two directors
are also directors of Lineo. Sales to Lineo amounted to $1,700 during the year
ended October 31, 1999.

MTI

     In July 1999, MTI, a company which at the time was 50 percent owned by
Canopy, agreed to purchase 5,333,333 shares of common stock for $6,000,000 of
which $3,000,000 was paid at closing and $3,000,000 was payable through an
interest bearing note receivable. Subsequent to October 31, 1999, the Company
agreed to forego the interest component of the note receivable in exchange for
an acceleration of the payment terms (see Note 6). A director of the Company is
the chairman of the board of MTI. Additionally, another Company director is the
current president and chief executive officer of MTI.

     The Company is using certain computer equipment provided by MTI without
charge. The equipment is valued at approximately $105,000. Sales to MTI amounted
to $2,985 during the year ended October 31, 1999.

(10) EMPLOYEE BENEFIT PLAN

     Until June 2000, Caldera utilized a 401(k) plan sponsored by Canopy for its
employees, through which Caldera made matching contributions from January 1
through June 2000. In June 2000, Caldera adopted its own 401(k) plan through
which eligible participants can elect to make contributions to the plan, subject
to certain limitations under the Internal Revenue Code. Under the terms of the
new plan, the Company may make discretionary matching contributions to partially
match employee contributions to the plan, up to predetermined limits.

(11) SIGNIFICANT CUSTOMERS

     During the year ended October 31, 1997, the Company did not have sales to
any one customer that accounted for more than ten percent of total revenue.
During the year ended October 31, 1998, the Company had sales to one customer
that accounted for approximately 11 percent of total revenue. During the year
ended October 31, 1999, the Company had sales to two customers that accounted
for approximately 33 percent and 20 percent of total revenue, respectively. No
other customer accounted for more than ten percent of total revenue during the
years ended October 31, 1998 and 1999.

(12) SEGMENT INFORMATION

     In June 1998, the FASB issued Statement of Financial Accounting Standards
No. 131, "Disclosures about Segments of an Enterprise and Related Information"
("SFAS 131"). SFAS 131 establishes disclosures related to components of a
company for which separate financial information is available and evaluated
regularly by a company's chief operating decision makers in deciding how to
allocate resources

and in assessing performance. It also requires segment disclosures about
products and services as well as geographic areas. The Company has determined
that it did not have any separately reportable operating segments as of October
31, 1997, 1998 and 1999. However, the Company does sell software and related
products in geographic locations outside of the United States. Revenue
attributed to individual countries based on the location of sales to
unaffiliated customers for the years ended October 31, 1997, 1998 and 1999 is as

     The Company is accounting for each of these investments in non-marketable
securities under the cost method as the Company has no ability to exercise
significant influence over any of the entities.

BUSINESS ALLIANCE WITH EVERGREEN INTERNET, INC.

     In January 2000, the Company and Evergreen Internet, Inc. ("Evergreen")
entered into a master agreement which sets forth the terms and conditions of a
business alliance. Evergreen and the Company agreed as follows: (i) Evergreen
granted to the Company an original equipment manufacturer license permitting the
bundling of certain of Evergreen's software products with the Company's software
products in exchange for the Company paying royalties to Evergreen based on
future sales; (ii) the Company and Evergreen will engage in joint development
and integration of their respective software products; (iii) the Company and
Evergreen will cooperate to create educational training courses for the combined
products; (iv) the Company agreed to acquire 370,370 shares of common stock of
Evergreen for $2,000,000 and Evergreen agreed to transfer an additional 222,222
shares of its common stock to the Company in exchange for 200,000 shares of the
Company's common stock (the 592,592 shares of Evergreen's common stock acquired
by the Company is approximately 4 percent of Evergreen's outstanding common and
preferred stock); and (v) the parties agreed to work together to identify new
business solution opportunities for their joint products. On January 10, 2000,
the Company paid the $2.0 million and issued 200,000 shares of common stock in
exchange for the 592,592 shares of Evergreen's common stock.

     As part of this agreement, the Company has agreed to pay $200,000 as a
license fee to Evergreen while $200,000 will be paid by Evergreen to the Company
as a license fee. The $200,000 to be paid by the Company to Evergreen will be
recorded as a component of cost of revenue and the $200,000 in proceeds to be
received from Evergreen will be recorded as an offset to cost of revenue.

     In addition to the above license fee, the Company and Evergreen have agreed
to certain referral fees. If the Company enters into a support agreement with a
customer that has been referred by Evergreen, the Company will pay a portion of
the total contract to Evergreen as a referral fee. The remaining portion of the
support agreement will be recorded as deferred revenue, and recognized ratably
over the term of the agreement. The referral fees will be recorded as sales and
marketing expenses as earned by Evergreen.

     The Company and Evergreen have also agreed to provide each other with
certain training and support services. Any out-of-pocket costs associated with
training activities to be provided by Evergreen to the Company, at no cost to
the Company, will be recorded as a cost of revenue. Additionally, the Company
has agreed to pay $20,000 per month to Evergreen for support services while
Evergreen has agreed to pay

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

$20,000 per month for support services provided by the Company. The cost of the
support services to be paid by the Company to Evergreen will be recorded as a
cost of revenue and the proceeds to be received from Evergreen will be recorded
as an offset to cost of revenue.

     The Company has recorded its investment in Evergreen at cost, based on the
cash consideration paid by the Company and the estimated fair market value of
the Company's common stock on the date of the agreement of $8.00 per share. The
Company determined that the estimated fair value of the Company's common stock
is more clearly evident of the value of the transaction since Evergreen is a
privately owned company. In management's opinion, the consideration exchanged by
the Company for the common shares of Evergreen was equal to the fair value of
the shares acquired. Furthermore, in management's opinion the terms of the OEM
arrangement and joint development and educational efforts are based on strategic
rationales and the related transactions will be at arm's length. The Company
currently intends on holding the shares indefinitely.

     The total investment of $3.6 million (unaudited) is included in the caption
Investments in Non-marketable Securities -- Non-affiliates in the accompanying
July 31, 2000 consolidated balance sheet.

STOCK EXCHANGE AGREEMENT WITH LINEO

     In January 2000, the Company and Lineo entered into a stock purchase and
sale agreement. Lineo is the successor entity to the operations of the
Predecessor which were not acquired by Caldera in the reorganization discussed
in Note 1 and in January 2000 was majority owned by Canopy. Pursuant to the
stock purchase agreement, the Company agreed to purchase 3,238,437 shares of
common stock of Lineo (approximately 17 percent of Lineo's outstanding voting
stock) in exchange for 1,250,000 shares of the Company's common stock.

     Because Lineo was also majority owned by Canopy, the investment in Lineo
has been accounted for as a transaction between entities under common control
with the transfer being reflected in the Company's financial statements at
Lineo's carry over basis. At the date of the agreement, Lineo had a
stockholders' deficit, of which approximately $150,000 (unaudited) would be
associated with the 17% interest the Company acquired. Accordingly, the
investment has been recorded at a nominal value of $1.00 because the Company
does not have any obligation to provide additional funding to Lineo. The Company
has recorded the estimated fair value of the shares of its common stock issued
to Lineo at $10.0 million with the difference between the $10.0 million and the
$1.00 investment recorded as a distribution to Canopy. Management anticipates
that royalties will be paid and or received based upon future sales of products
by either the Company or Lineo which incorporate each other's technology or
technology developed jointly.

     On May 11, 2000, Canopy transferred 1,761,563 shares of Lineo's common
stock held by Canopy to Caldera Systems. This transfer has been reflected as a
capital contribution by Canopy at Lineo's carry over basis of $1,966,173
(unaudited). As a result of this transaction, the Company currently holds a
total of 5,000,000 shares of Lineo's common stock (approximately 14 percent of
Lineo's outstanding voting stock). The total investment of $1,966,174
(unaudited) is included in the caption Investments in Non-marketable
Securities -- Affiliate in the accompanying July 31, 2000 consolidated balance
sheet.

     On August 31, 2000, the Company, Canopy and Metrowerks Holdings, Inc.
("Metrowerks"), an affiliate of Motorola, Inc., entered into a Stock Purchase
and Sale Agreement whereby the Company and Canopy will sell 2.0 million and 1.0
million shares, respectively, of common stock of Lineo to Metrowerks at $7.50
per share. The sale is expected to close upon the receipt of certain required
regulatory approvals and the completion of other closing conditions.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

     In conjunction with the sale of the common stock of Lineo, the Company also
entered into a stockholder agreement among and between Canopy, Lineo and certain
other stockholders of Lineo which provides for a right of first refusal for the
benefit of Metrowerks with respect to Lineo shares held by the Company and other
Lineo stockholders. The Company has also agreed to indemnify Metrowerks up to an
amount equal to the amount of proceeds received by the Company for any damages
sustained by Metrowerks as a result of breaches by the Company under the stock
purchase and sale agreement and the stockholder agreement or for breaches by
Lineo under a warrant agreement between Lineo and Metrowerks.

     The difference between the $7.50 per share price to be received from
Metrowerks and the Company's per share carrying value will be recorded as a
contribution to equity.

STOCK EXCHANGE AGREEMENT WITH TROLL TECH AS

     In December 1999, the Company and Canopy entered into an agreement with
Troll Tech AS and its stockholders. Pursuant to the agreement, the Company
agreed to acquire 159 shares of common stock of Troll Tech (approximately 2
percent of Troll Tech's outstanding common stock) in exchange for 106,356 shares
of the Company's common stock and Canopy agreed to acquire 398 shares of common
stock of Troll Tech in exchange for $1,000,000, payable in monthly installments
of $100,000. The agreement also grants to Canopy and its affiliates certain
license rights with respect to Troll Tech's software. Royalties will be paid
based upon future sales of products by the Company.

     The Company has recorded its investment in Troll Tech's common stock at
$399,999, based on the cash price per share paid by Canopy. The Company
determined that the cash price per share paid by Canopy is the most reliable
evidence of the value of Troll Tech's common stock. The difference between the
estimated fair value of the 106,356 shares of the Company's common stock at
$8.00 per share of $850,848 and the $399,999 investment was recorded as a
license fee. The license fee was classified as contra-equity and was
subsequently reflected as a distribution to Canopy because the license rights
were used by Canopy and its affiliates. The Company currently intends on holding
the shares of Troll Tech indefinitely.

     The total investment of $399,999 (unaudited) is included in the caption
Investments in Non-marketable Securities -- Non-affiliates in the accompanying
July 31, 2000 consolidated balance sheet.

(14) SUBSEQUENT EVENT (UNAUDITED)

PROPOSED ACQUISITION OF THE SANTA CRUZ OPERATION'S SERVER SOFTWARE AND
PROFESSIONAL SERVICES DIVISIONS

     On August 1, 2000, Caldera, Caldera, Inc. ("New Caldera"), and The Santa
Cruz Operation, Inc. ("SCO") entered into an Agreement and Plan of
Reorganization (the "Reorganization Agreement"). As a result of the transactions
proposed by the Reorganization Agreement (the "Reorganization"), (i) a newly
formed, wholly-owned subsidiary of New Caldera will be merged with and into
Caldera, with Caldera being the surviving corporation, and all outstanding
Caldera securities will be converted, on a share for share basis, into New
Caldera securities having identical rights, preferences and privileges, with New
Caldera assuming any and all outstanding options and other rights to purchase
shares of capital stock of Caldera (with all such New Caldera securities issued
to former Caldera security holders initially representing a fully-diluted equity
interest in New Caldera equal to approximately 71.4 percent in New Caldera);
(ii) SCO and certain of its subsidiaries will contribute to New Caldera, all of
the capital stock held of certain contributed companies as well as certain
assets of SCO, collectively representing the Server and Professional Services
Groups of SCO, in consideration for the issuance by New Caldera to SCO of shares
of common stock of New Caldera, $0.001 par value ("New Caldera Common Stock");

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

(iii) New Caldera will assume all options to acquire common stock of SCO held by
SCO employees (other than certain officers of SCO) hired or retained by Caldera
and such options will be converted into options to purchase New Caldera Common
Stock on a two-for-one basis (the "New Caldera Options"); and (iv) SCO will
receive shares of New Caldera Common Stock (including shares reserved for New
Caldera Options) representing in the aggregate a fully diluted equity interest
in New Caldera equal to approximately 28.6 percent of New Caldera and $7,000,000
in cash. In conjunction with the Reorganization Agreement, Canopy has agreed to
loan $18 million to SCO and Caldera has agreed to loan $7 million to SCO. The
assets of SCO will secure each of these loans.

     In addition, certain stockholders of SCO and certain stockholders of
Caldera have entered into Voting Agreements to vote in favor of the
Reorganization and against certain other matters (the "Voting Agreements"). The
Reorganization is intended to constitute a tax-free reorganization under Section
351 of the Internal Revenue Code. Consummation of the Reorganization is subject
to various conditions, including, among other things, receipt of the necessary
approvals of the stockholders of Caldera, shareholders of SCO and certain
regulatory bodies.

     The acquisition of the Server and Professional Services Groups will be
accounted for using the purchase method of accounting. Under this method, the
total purchase price, including fees and expenses, is allocated to the tangible
and identifiable intangible assets acquired and the liabilities assumed based
upon their respective fair values as of the effective date of the acquisition.
The remaining purchase price over the net tangible and identifiable intangible
assets will be allocated to goodwill.

                       REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Directors and Shareholders of The Santa Cruz Operation, Inc.:

In our opinion, the accompanying consolidated balance sheets and the related
consolidated statements of operations, of divisional deficit and accumulated
other comprehensive loss and cash flows present fairly, in all material
respects, the financial position of the SCO Server and Professional Services
Groups at September 30, 1999 and June 30, 2000, and the results of their
operations and their cash flows for each of the two years in the period ended
September 30, 1999 and the nine months ended June 30, 2000 in conformity with
accounting principles generally accepted in the United States of America. These
financial statements are the responsibility of the management of The SCO Server
and Professional Services Groups; 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 auditing standards generally accepted in the
United States of America, 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 our opinion.

As discussed in Note 1 to these consolidated financial statements, The SCO
Server and Professional Server Groups are dependent upon financing from The
Santa Cruz Operation Inc. ("SCO"). There can be no assurance that SCO will
provide such funding beyond June 30, 2001.

                THE SCO SERVER AND PROFESSIONAL SERVICES GROUPS

              NOTES TO CONSOLIDATED CARVE OUT FINANCIAL STATEMENTS

(1) INTRODUCTION AND BASIS OF PRESENTATION

     On August 1, 2000 The Santa Cruz Operation, Inc. ("SCO") announced that it
had reached an agreement with Caldera Systems, Inc.("Caldera") under which
Caldera would purchase for stock and cash the SCO server and professional
services groups (the "Groups"). Under the terms of the agreement SCO would
retain the rights to its OpenServer Product with Caldera continuing to act as a
sales agent on SCO's behalf for this product. Under the terms of a Sales and
Support Agreement and a Research and Development Agreement between the parties
Caldera will receive a commission based on the gross margin earned by SCO on
each sale. In addition Caldera will receive reimbursements for product
development and selling and marketing expenses incurred in respect to the
OpenServer Product.

     The SCO server and professional services groups operate as a provider of
server software for networked business computing. The solutions delivered by the
Groups are UNIX(R) based server operating systems. The Groups' products enable
business and government organizations of all sizes to integrate technologies and
products from different vendors to create cost-effective, powerful, networked
information systems that perform highly complex, mission-critical business
functions. Products are sold via the Groups' direct sales force or through
indirect channel partners, which include some of the leading distribution
companies within the United States, Europe and the rest of the world.

     The consolidated financial statements include the assets, liabilities,
operating results and cash flows of the SCO server and professional services
groups and have been prepared using SCO's historical bases in the assets and
liabilities and the historical results of the Groups' operations. Changes in
divisional deficit represent SCO's funding of the groups, after giving effect to
the net earnings of the Groups plus net cash transfers to and from SCO. No
interdivision interest income or expense has been allocated to, or included in,
the accompanying consolidated financial statements.

     The consolidated financial statements include allocations of certain SCO
corporate expenses, including centralized research and development, legal,
accounting, employee benefits, real estate, insurance services, information
technology services, treasury and other SCO corporate and infrastructure costs.
The expense allocations have been determined on bases deemed appropriate for
each expense item. Such bases include relative headcount, relative space
occupancy and relative sales volume. SCO and management of the Groups consider
these allocations to be a reasonable reflection of the utilization of services
provided or the benefit received by the Groups.

     However, the financial information included herein may not reflect the
consolidated financial position, operating results, changes in divisional
deficit and cash flows of the Groups in the future or what they would have been
had the Groups had operated as a separate, stand-alone entity during the periods
presented.

DEPENDENCE UPON SCO FUNDING

     The Groups have incurred losses from operations in each of the last two
fiscal years and during the nine months ended June 30, 2000 and have relied upon
SCO to provide adequate financing to fund these losses. Management of the Groups
expect to incur further losses from operations and have received a commitment
from SCO to provide further funding until June 30, 2001, however, there can be
no assurance that SCO will provide funding beyond this date. SCO has incurred
losses from operations of approximately $37.1 million during the nine months
ended June 30, 2000 and revenues have declined from $165.5 million for the nine
months ended June 30, 1999 to $116.1 million for the nine months ended June 30,
2000. SCO has recently announced cost reduction plans (see Note 13) in order to
reduce operating expenses to levels consistent with current revenues and is
investigating financing alternatives. There can be no assurance that such cost
reduction measures will be adequate or that such financing will be available, if
at all, on terms acceptable to SCO.

     The consolidated financial statements include the results of the overseas
incorporated entities which form part of the Groups. These entities are wholly
and majority-owned subsidiaries of the SCO server and professional services
groups. All significant intradivision transactions and balances have been
eliminated.

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, the
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. Such estimates include the allowances for bad debt, product
returns and certain accrued expenses and liabilities, and the valuation
allowance for deferred tax assets. Actual results could differ from those
estimates.

CASH EQUIVALENTS AND INVESTMENTS

     Historically, SCO has managed cash and cash equivalents on a centralized
basis. Cash receipts associated with the Groups' business except for amounts
arising from specific research and development funding contracts have been
transferred to SCO on a daily basis and SCO has funded the Groups'
disbursements.

PROPERTY AND EQUIPMENT

     Property and equipment are stated at cost and, except for assets recorded
under capital lease and leasehold improvements, are depreciated using the
straight-line method over the estimated useful lives of the assets, ranging from
three to five years. Leasehold improvements and assets recorded under
capitalized leases are amortized using the straight-line method over the lesser
of the remaining term of the lease or the estimated economic life of the asset,
ranging from one to ten years.

PURCHASED SOFTWARE AND TECHNOLOGY LICENSES

     Purchased software consists of core intellectual property rights owned by
SCO but which relate to the Groups products. Technology licenses represent
payments for the rights to use and integrate third party technology into the
Groups' product offerings. Amounts capitalized are amortized on a straight-line
basis over the estimated product life, ranging from three to six years, or on
the ratio of current revenues to total projected product revenues, whichever is
greater.

ACCOUNTING FOR LONG-LIVED ASSETS

     The Groups review property and equipment and purchased software and
technology licenses for impairment whenever events or changes in circumstances
indicate that the carrying amount of an asset may not be recoverable.
Recoverability is measured by comparison of its carrying amount to estimated
future net cash flows the assets are expected to generate. If such assets are
considered to be impaired, the impairment to be recognized is measured by the
amount by which the carrying value of the asset exceeds the projected discounted
future operating cash flows.

SOFTWARE DEVELOPMENT COSTS

     Statement of Financial Accounting Standards ("SFAS") No. 86 provides for
the capitalization of certain software development costs once technological
feasibility is established. Capitalized costs are then

amortized on a straight-line basis over the estimated product life, or on the
ratio of current revenues to total projected product revenues, whichever is
greater. Through June 30, 2000, Management believes its process for developing
software was essentially completed concurrent with the establishment of
technological feasibility, and accordingly, no software development costs have
been capitalized to date.

REVENUE RECOGNITION

     The Groups' revenue is derived primarily from two sources, across many
industries: (i) products license revenue, derived primarily from product sales
to resellers and end users, including large scale enterprises and royalty
revenue, derived primarily from initial license fees and ongoing royalties from
product sales by source code OEMs; and (ii) service and support revenue, derived
primarily from providing software updates, support and education and consulting
services to end users.

     The Groups adopted the provisions of Statement of Position 97-2, or SOP
97-2, Software Revenue Recognition, as amended by Statement of Position 98-4,
Deferral of the Effective Date of Certain Provisions of SOP 97-2, effective
October 1, 1998. SOP 97-2 supersedes Statement of Position 91-1, Software
Revenue Recognition, and delineates the accounting for software product and
maintenance revenue. Under SOP 97-2, the Groups recognize product revenue upon
shipment if a signed contract exists, the fee is fixed and determinable,
collection of resulting receivables is probable and product returns are
reasonably estimable, except for sales to distributors, which are recognized
upon sale by the distributor to resellers or end users. Estimated product
returns are recorded upon recognition of revenue from customers having rights of
return. Revenue from sales to distributors is recognized as sell through by the
distributors as returns cannot be reasonably estimated. In 1998, the Groups'
revenue recognition policy was the same as set forth above.

     For contracts with multiple obligations (e.g. deliverable and undeliverable
products, maintenance and other services), the Groups allocate revenue to each
component of the contract based on objective evidence of its fair value, which
is specific to the Groups, or for products not being sold separately, the price
established by management. The Groups recognize revenue allocated to undelivered
products when the criteria for product revenue set forth above are met. The
Groups recognize revenue from maintenance fees for ongoing customer support and
product updates ratably over the period of the maintenance contract. Payments
for maintenance fees are generally made in advance and are non-refundable. For
revenue allocated to education and consulting services or derived from the
separate sale of such services, the Groups recognize revenue as the related
services are performed. In 1998, the revenue recognition policy for maintenance,
education and consulting services was the same as set forth above.

     The Groups recognize product revenue from royalty payments upon receipt of
quarterly royalty reports from OEMs related to their product sales.

     The Groups perform ongoing credit evaluations of its customers' financial
condition and does not require collateral. The Groups maintain allowances for
potential credit losses and such losses have been within management's
expectations.

COOPERATIVE ADVERTISING

     The Groups expense advertising costs as incurred. The Groups reimburse
certain qualified customers for a portion of the advertising costs related to
their promotion of the Groups' products. The Groups' maximum liability for
reimbursement is accrued at the time revenue is recognized. For the years ended
September 30, 1999 and 1998, and the nine months ended June 30, cooperative
advertising expense totaled approximately $9.2 million, $10.5 million and $6.5
million, respectively.

INCOME TAXES

     The Groups' operating results historically have been included in SCO's
consolidated U.S. and state income tax returns and in tax returns of certain SCO
foreign subsidiaries. The provision for income taxes in the Groups' consolidated
financial statements has been determined on a separate-return basis. The Groups
record income taxes using an asset and liability approach that results in the
recognition of deferred tax assets and liabilities for the expected future tax
consequences of events that have been recognized in the Groups' consolidated
financial statements or tax returns. In estimating future tax consequences, all
expected future events other than enactment of changes in tax laws are
considered. When necessary, a valuation allowance is recorded to reduce tax
assets to an amount whose realization is more likely than not.

COMPREHENSIVE INCOME

     In the first quarter of fiscal 1999, the Groups adopted SFAS No. 130,
Reporting Comprehensive Income. Under SFAS No. 130 the Groups are required to
report comprehensive income, which includes the Groups' net income, as well as
changes in divisional equity from other sources. In the Groups' case, the only
change in equity included in comprehensive income is the foreign currency
cumulative translation adjustment. The adoption of SFAS 130 had no net impact on
the Divisions' net income, balance sheet or shareholders' equity.

SEGMENT INFORMATION

     In 1999, the Groups adopted SFAS No. 131, Disclosures about Segments of an
Enterprise and Related Information.  SFAS No. 131 supersedes SFAS No. 14,
Financial Reporting for Segments of a Business Enterprise.  Under the new
standard the Groups are required to use the "management" approach to reporting
their segments. The management approach designates the internal organization
used by management for making operating decisions and assessing performance as
the source of the Groups' segments. The adoption of SFAS No. 131 had no impact
on the Groups' net income, balance sheet or shareholders' equity.

RECENT ACCOUNTING PRONOUNCEMENTS

     In June 1998, the Financial Accounting Standards Board ("FASB") issued SFAS
No. 133, Accounting for Derivative Instruments and Hedging Activities, which
establishes accounting and reporting standards for derivative instruments and
hedging activities. It requires that an entity recognize all derivatives as
either assets or liabilities in the statement of financial position and measure
those instruments at fair value. In June 1999, the FASB issued SFAS No. 137,
Accounting for Derivative Instruments -- Deferral of the Effective Date of SFAS
Statement No. 133 and in June 2000, the FASB issued SFAS No. 138, Accounting for
Certain Derivative Instruments -- an amendment of FAS 133, Accounting for
Derivative instruments and Hedging Activities.  As a result of SFAS No. 137,
SFAS No. 133 and SFAS No. 138 will be effective for all fiscal quarters of all
fiscal years beginning after June 15, 2000. The Groups do not expect that the
adoption of this standard will have a material impact on their financial
position and results of operations.

     In March 2000, the FASB issued FASB Interpretation No. 44, Accounting for
Certain Transactions Involving Stock Compensation -- an interpretation of APB
Opinion No. 25.  FIN 44 clarifies the application of Opinion 25 for (a) the
definition of employee for purposes of applying Opinion 25, (b) the criteria for
determining whether a plan qualifies as a noncompensatory plan, (c) the
accounting consequence of various modifications to the terms of a previously
fixed stock option or award, and (d) the accounting for an exchange of stock
compensation awards in a business combination. FIN 44 is effective

        NOTES TO CONSOLIDATED CARVE OUT FINANCIAL STATEMENTS (CONTINUED)

July 1, 2000, but certain conclusions cover specific events that occur after
either December 15, 1998, or January 12, 2000. The adoption of the conclusions
covering the specific events after either December 15, 1998 or January 12, 2000
did not have a material effect on the financial position or results of
operations of the Groups. Management believes that the impact of the remaining
provisions of FIN 44 will not have a material effect on the Groups' financial
position or results of operations.

     In December 1999, the Securities and Exchange Commission ("SEC") issued
Staff Accounting Bulletin No. 101 (SAB 101), Revenue Recognition in Financial
Statements, which provides guidance on the recognition, presentation and
disclosure of revenue in financials filed with the SEC. SAB 101 outlines the
basic criteria that must be met to recognize revenue and provides guidance for
disclosures related to revenue recognition policies. The Groups must adopt SAB
101 in the first quarter of fiscal 2001. Management believes that the impact of
SAB 101 will not have a material effect on the Groups' financial position or
results of operations. However, the interpretation of SAB 101 is still under
discussion by the Securities and Exchange Commission and may be revised. The
adoption of any such revisions could have a material effect on the Groups'
financial position or results of operations.

STOCK-BASED COMPENSATION

     The Groups account for stock-based compensation plans using the intrinsic
value method. As such, compensation expense would be recorded on the date of
grant only if the current market price of the underlying stock exceeded the
exercise price.

FOREIGN CURRENCY TRANSLATION

     The functional currency of the Groups' foreign subsidiaries is the local
foreign currency. All assets and liabilities denominated in foreign currencies
are translated into U.S. dollars at the exchange rates prevailing on the balance
sheet date. Revenues, costs and expenses are translated at average rates of
exchange prevailing during the period. Translation adjustments resulting from
translation of interdivision accounts are accumulated as a separate component of
divisional deficit. Gains and losses resulting from foreign currency
transactions are included in the consolidated statements of operations and have
not been significant.

FAIR VALUE OF FINANCIAL INSTRUMENTS

     Carrying amounts of certain of the Groups' financial instruments, including
cash and cash equivalents, accrued payroll and other accrued liabilities,
approximate fair value because of their short maturities.

     The cost of assets recorded under capital leases was $12.1 million and $7.1
million at September 30, 1999 and June 30, 2000, respectively. Accumulated
amortization on those dates was $7.3 million and $4.8 million, respectively.

     Rent expense amounted to approximately $7.0 million and $7.0 million, and
$5.0 million in the years ended September 30, 1998 and 1999, and the nine months
ended June 30, 2000 respectively.

     Included within SCO's operating lease commitments recharged to the Groups
are facilities leased from Encinal Partners, a partnership which includes both
SCO's President and Chief Executive Officer and a principal shareholder. SCO's
Board of Directors has reviewed and approved the lease agreements and determined
that the lease agreements entered into by SCO are equivalent to agreements that
would be

negotiated with independent third parties on an "arms-length" basis. The
remaining lease term of these facilities is between one and six years. Rent
expense for these facilities amounted to approximately $0.4 million in each of
the years ended September 30, 1998 and 1999, and the nine months ended June 30,
2000.

CONTINGENCIES

     In December 1995, SCO acquired from Novell certain assets related to
UnixWare, one of the products currently sold by the Groups. As consideration,
SCO may be required to make cash payments periodically to Novell provided
certain unit volumes of UNIX distribution are achieved, and SCO will be
reimbursed by the Groups. To date, distribution unit volume of UNIX has not
reached levels which have required SCO to make cash payments to Novell. Such
payment obligation will terminate at the end of calendar year 2002.

     From time to time, SCO and the Groups may experience claims on behalf of
the Groups in the ordinary course of business, including among others employee
legal actions and alleged trademark infringements. Due to the nature of these
matters, it is not possible to either determine the range of loss that may
result from them or their ultimate resolution.

(9) EMPLOYEE BENEFITS

SAVINGS PLAN

     SCO maintains an employee savings plan, which qualifies under section
401(k) of the Internal Revenue Code. Under the plan, participating U.S.
employees may defer up to 20% of their pre-tax salary, up to certain statutory
limits. SCO matches 50% of employee contributions up to the lower of 6% of the
employee's annual salary or $3,000. For fiscal 1998, 1999 and 2000, the Groups'
total contributions towards the 401(k) plan amounted to $0.8 million, $0.9
million and $0.5 million, respectively.

1993 EMPLOYEE STOCK PURCHASE PLAN

     SCO sponsors an Employee Stock Purchase Plan "ESPP" for all eligible
employees which is administered by the Board of Directors. Under the ESPP,
shares of SCO's ESPP stock may be purchased at six-month intervals at 85% of the
fair market value on the first or last day of each six-month period whichever is
lower. Employees may purchase shares through payroll deductions of up to 10% of
gross compensation during an offering period. During the years ended September
30, 1998 and 1999 and the nine months ended June 30, 2000, employees of the
Groups purchased 187,324, 324,482 and 137,151 shares at an average per share
price of $3.07, $3.52, and $3.13, respectively. The number of shares reserved
for issuance under the Purchase Plan increased by 750,000 shares in February
1999. As of June 30, 2000 a total of 1,617,057 shares were reserved for future
issuance.

1994 INCENTIVE STOCK OPTION PLAN

     As of June 30, 2000, SCO had authorized 20,013,665 shares of Common Stock
for issuance under the 1994 Incentive Stock Option Plan (the "Option Plan").
SCO's Board of Directors administers the Option Plan and determines the terms of
the options granted under the Option Plan, including the exercise price, number
of shares subject to each option and the exercisability thereof. In addition,
the stock option committee of SCO's Board of Directors is authorized to grant up
to 20,000 shares to an individual employee or consultant under the terms of the
Option Plan.

     The exercise price of all incentive options granted under the Option Plan
must be at least equal to the fair market value of SCO stock. Options granted
under the Option Plan prior to January 31, 1996

generally become exercisable over a five year period. Effective January 31,
1996, the vesting period for subsequent grants was changed to four years. The
term of each option is ten years.

1993 DIRECTOR OPTION PLAN

     SCO's 1993 Director Option Plan (the "Director Plan") provides for the
granting of nonstatutory stock options to non-employee directors of SCO and is
administered by the Board of Directors. In February of 2000, the number of
shares available for issuance under the Director Plan was increased by 250,000
shares from 1,150,000 shares to 1,400,000 shares.

     A summary of the status of the options held by the Groups' employees under
SCO's stock option plans as of September 30, 1998, and 1999, and June 30, 2000
and changes during the periods then ended is presented below:

PRO FORMA FAIR VALUE ACCOUNTING FOR STOCK-BASED COMPENSATION

     SFAS No. 123, Accounting for Stock-Based Compensation, requires pro forma
information regarding net income and earnings per share be determined as if the
Company had accounted for its employee stock options and other stock-based
compensation granted subsequent to September 30, 1996 under the fair value
method of that Statement. The fair value of the options granted to the employees

under SCO's Incentive Option Plan and the Director Option Plan was estimated at
the date of grant using a Black-Scholes option pricing model with the following
weighted-average assumptions for the years ended September 30, 1998 and 1999 and
the nine months ended June 30, 2000: risk-free interest rate of 5.45% for 1998,
5.27% for 1999 and 6.45% for June 2000; dividend yield of 0%; volatility factor
of the expected market price of SCO's common stock of 65%; an average turnover
rate of 15% and a four year and five year expected life for options granted to
employees and executives of the Groups, respectively.

     The fair value for the Employee Stock Purchase Plan rights were also
estimated at the date of grant using a Black-Scholes option pricing model with
the following assumptions for the year ended September 30, 1998 and 1999 and the
nine months ended June 30, 2000: risk-free interest rates of 5.31% 4.91% and
6.45% respectively; dividend yield of 0%; volatility factors of 65%; and six
month expected life. The weighted average fair value of the ESPP rights granted
during the nine months ended June 30, 2000 and in the year ended September 30,
1998 and 1999 and the nine months ended June 30, 2000 was $1.27, $1.31 and

under which Caldera will acquire the SCO server and professional services
groups. Caldera Systems, Inc. will form a new holding company, Caldera, Inc., to
acquire assets from the SCO server and professional services groups, including
its employees, products and channel resources. Caldera, Inc. will have exclusive

aggregate of approximately 17.54 million shares of Caldera stock (including
approximately 2 million shares reserved for employee options assumed by Caldera,
Inc. for options currently held by SCO employees joining Caldera, Inc.), and
$7.0 million in cash. In conjunction with the acquisition, The Canopy Group,
Inc., a major stockholder of Caldera Systems, Inc.,

has agreed to loan $18.0 million to SCO. The terms of this loan are still to be

customary. Further, Caldera Systems, Inc. has agreed to loan $7.0 million to the
Company in the form of a short-term note repayable at the consummation of the
transaction between SCO and Caldera Systems, Inc. SCO will retain its Tarantella
Group and the SCO OpenServer revenue stream and intellectual properties. The
boards of directors of both companies have unanimously approved the acquisition
which is subject to the approval of Caldera Systems, Inc. and The Santa Cruz
Operation, Inc. stockholders, and regulatory agencies, as well as meeting
certain other closing conditions.

     On September 7, 2000, SCO announced the terms of a proposed restructuring
plan affecting the server and professional services groups. Under the terms of
the plan the workforce of the Groups will be reduced by approximately 190
employees. As a result of this restructuring SCO expects to record a charge
estimated at between $5 million and $6 million during the quarter ending
September 30, 2000.

                      AGREEMENT AND PLAN OF REORGANIZATION

     THIS AGREEMENT AND PLAN OF REORGANIZATION (this "Agreement") is entered
into as of August 1, 2000, by and among Caldera Systems, Inc., a Delaware
corporation including for all purposes Caldera Surviving Corporation,
("Caldera"), Caldera Holding, Inc., a Delaware corporation ("Newco") and The
Santa Cruz Operation, Inc., a California corporation ("SCO"). The terms defined
in Section 13.15 of this Agreement shall have the meanings therein specified in
this Agreement.

                                    RECITALS

     A. The parties intend that, subject to the terms and conditions of this
Agreement, (i) a new Delaware corporation referred to herein as Newco has been
formed by Caldera solely for the purpose of the transactions contemplated
hereunder; (ii) a newly formed, wholly owned subsidiary of Newco ("Merger Sub")
will be merged with and into Caldera, with Caldera being the surviving
corporation of such merger (the "Merger"), and all outstanding Caldera
securities will be converted, on a share for share basis, into Newco securities
having identical rights, preferences and privileges, with Newco assuming any and
all outstanding options and other rights to purchase shares of capital stock of
Caldera (with all such Newco securities issued to former Caldera security
holders initially representing the Caldera Percentage Interest in Newco), all on
the terms set out in this Agreement and in the Certificate of Merger
substantially in the form of Exhibit A hereto (the "Certificate of Merger") and
the applicable provisions of Delaware Law; (iii) SCO and certain of its
subsidiaries as herein specified will contribute to Newco, all on the terms
herein specified, all of the Contributed Stock of the Contributed Companies
(with each of the Contributed Companies thereby becoming a wholly owned
subsidiary of Newco) and the Contributed Assets in consideration for the
issuance by Newco to SCO of shares of Common Stock of Newco, $0.001 par value
("Newco Common Stock"), and (iv) Newco will assume all options to acquire common
stock of SCO held by the Employees (other than David McCrabb, Jack Moyer and Jim
Wilt) hired or retained by Caldera (the "Optionees") and such options will be
converted into options to purchase Newco Common Stock ("Newco Options") as set
forth herein, which Newco Common Stock issued to SCO and Newco Options will
represent in the aggregate a fully diluted equity interest in Newco equal to the
difference between 100% and the Caldera Percentage Interest. The transactions
described in subpart (iii) and (iv) of the foregoing sentence are collectively
the "SCO Transaction."

     B. The Newco Common Stock and the Newco Options issued in the Merger and in
the SCO Transaction will be registered under the Securities Act, pursuant to a
Newco registration statement on Form S-4 or Form S-8, as set forth herein.

     C. For federal income tax purposes, it is intended that (i) the Merger
qualify as a reorganization under the provisions of Section 368(a) of the
Internal Revenue Code and (ii) that the Merger and the portion of the SCO
Transaction described in Recital A (iii) above qualify as an exchange under the
provisions of Section 351 of the Internal Revenue Code.

     NOW, THEREFORE, the parties hereto hereby agree as follows:

     1. Plan of Reorganization.

     1.1 The Organization of Newco and Merger Sub.  Caldera has formed Newco
under the laws of the State of Delaware for the purposes of the transactions
contemplated by the Merger and in accordance with the terms of this Agreement.
Newco currently has no outstanding securities and has conducted no business and,
prior to the Effective Time, will not issue any securities, will conduct no
business or operations, will have no assets and will enter into no agreements
nor incur any obligations or Liabilities, except as required or contemplated by
this Agreement or necessary to perform its obligations hereunder. As soon as
practicable after the date hereof, Newco shall form the Merger Sub as a wholly
owned subsidiary, which will conduct no business prior to Closing except as
expressly contemplated hereunder.
<PAGE>   250

     1.2  The Merger.  At the Closing, subject to the terms and conditions of
this Agreement, Caldera will execute and deliver and will file with the
Secretary of State of the State of Delaware in accordance with relevant
provisions of the Delaware Law, a Certificate of Merger providing for the Merger
of Merger Sub with and into Caldera, with Caldera being the surviving
corporation upon the effectiveness of the Merger and thereby becoming a wholly
owned subsidiary of Newco, pursuant to this Agreement, the Certificate of Merger
and in accordance with applicable provisions of the Delaware Law as follows:

          (a) Conversion of Caldera Common Stock.  Each share of the Common
     Stock of Caldera ("Caldera Common Stock") that is issued and outstanding
     immediately prior to the Effective Time will by virtue of the Merger and at
     the Effective Time, and without any further action on the part of Caldera,
     Newco or any holder of Caldera Common Stock, be converted into one share
     (the "Caldera Ratio") of validly issued, fully paid and nonassessable Newco
     Common Stock.

          (b) Conversion of Caldera Options.

             (i) Conversion.  At the Effective Time, each of the then
        outstanding options to purchase shares of Caldera Common Stock
        (collectively, the "Caldera Options") (consisting of all outstanding
        options granted under the stock option plans of Caldera or the Caldera
        Subsidiaries, including but not limited to its 1998 Stock Option Plan
        and its 1999 Omnibus Stock Incentive Plan (collectively, the "Caldera
        Plans"), and any individual non-Plan options), will, by virtue of the
        Merger, and without any further action on the part of any holder
        thereof, be assumed by Newco and converted into an option to purchase an
        equivalent number of shares of Newco Common Stock, at an exercise price
        per share equal to the per share exercise price of such Caldera Option
        in effect at the Effective Time. The term, exercisability, vesting
        schedule, status as an "incentive stock option" under Section 422 of the
        Internal Revenue Code, if applicable, and all other terms and conditions
        of the Caldera Options will be unchanged and all references in any
        option agreement governing such option to Caldera shall be deemed to
        refer to Newco, where appropriate. Continuous service as an employee or
        consultant with Caldera or any of the Caldera Subsidiaries will be
        credited to an optionee of Caldera for purposes of determining the
        number of shares of Newco Common Stock vested and exercisable under the
        assumed Caldera Option after the Closing.

             (ii) Stock Rights.  At the Effective Time, Newco will assume all of
        Caldera's obligations under Caldera's 2000 Employee Stock Purchase Plan
        (the "Caldera Stock Purchase Plan") and each of the then outstanding
        rights to purchase shares of Caldera Common Stock under such plan
        (collectively, the "Caldera Stock Purchase Plan Rights"), will by virtue
        of the Merger, and without any further action on the part of any holder
        thereof, be assumed and converted into a right to purchase the same
        number of shares of Newco Common Stock on the next "purchase date" (as
        such term is defined in the Caldera Stock Purchase Plan) following the
        Effective Time at a purchase price per share determined in accordance
        with the Caldera Stock Purchase Plan.

          (c) Cancellation of Caldera-Owned Shares.  Each share of Caldera
     Common Stock held in the treasury of Caldera or any of which are owned by
     Newco, Caldera, or any direct or indirect wholly owned subsidiary of Newco
     or Caldera immediately prior to the Effective Time shall be cancelled and
     extinguished without any conversion thereof.

     1.3  SCO Transaction.

          (a) Issuance of Newco Common Stock.  At the Effective Time and subject
     to the terms and conditions of this Agreement, Newco will, in consideration
     for the contribution and transfer of the Contributed Stock and Contributed
     Assets to Newco as contemplated by this Agreement, perform the following:

             (i) Consideration.  Issue to SCO that number of issued, fully paid
        and nonassessable shares of Newco Common Stock equal to The SCO
        Percentage Interest, less (a) the number of shares of Newco Common Stock
        issuable upon exercise of the Newco Options pursuant to

                                       A-2
<PAGE>   251

        Section 1.3(a)(iii) below and (b) the Escrow Shares issued to SCO and
        placed directly into escrow by Caldera pursuant to Section 1.3(b) below,
        with such number of shares to be appropriately adjusted in the event of
        any Caldera stock split, stock combination, reclassification or other
        similar capital change (the "First SCO Certificate") and pay SCO cash
        consideration equal to seven million dollars ($7,000,000) (the "Cash
        Consideration"), by wire transfer of immediately available funds or upon
        the cancellation of SCO's outstanding indebtedness to Caldera.

             (ii) [Intentionally Omitted.]

             (iii) Assumption and Conversion of SCO Options.  At the Effective
        Time, each of the then outstanding options to purchase shares of SCO
        Common Stock held by the Optionees (collectively, the "SCO Options")
        (consisting of all outstanding options granted under the stock option
        plans of SCO or the SCO Subsidiaries, and any individual non-plan
        options held by the Optionees), will, by virtue of the Merger, and
        without any further action on the part of any holder thereof, be assumed
        by Newco and converted into an option to purchase one share of Newco
        Common Stock for each two shares of SCO Common Stock subject to a SCO
        Option at the Effective Time (the "SCO Ratio") at an exercise price per
        share of Newco Common Stock equal to the exercise price per share of
        such assumed SCO Option immediately prior to the Effective Time divided
        by the SCO Ratio, rounded up to the nearest cent. Except as set forth in
        the preceding sentence, the term, exercisability, vesting schedule, and
        all other terms and conditions of the SCO Options will be unchanged and
        all references in any option agreement governing such option to SCO
        shall be deemed to refer to Newco, where appropriate; provided, however,
        that the outstanding SCO Options previously designated as "incentive
        stock options" under Section 422 of the Internal Revenue Code may, as a
        result of the foregoing adjustments, be converted into non-statutory
        stock options. Continuous service as an employee or consultant with SCO
        or any of the SCO Subsidiaries will be credited to the Optionee for
        purposes of determining the number of shares of Newco Common Stock
        vested and exercisable under the assumed SCO Option after the Closing.
        If the foregoing calculation results in a Newco Option, which is issued
        for a SCO Option, being exercisable for a fraction of a share of Newco
        Common Stock, then the number of shares of Newco Common Stock subject to
        such option will be rounded down to the nearest whole number of shares,
        with no cash being payable for such resulting fractional share.

          (b) Escrow.  As soon as practicable after the Effective Time, and
     subject to and in accordance with the provisions of Section 10 and the
     Escrow Agreement, a form of which is attached as Exhibit 1.3(b) (the
     "Escrow Agreement"), Caldera shall deliver to the Escrow Agent on behalf of
     SCO a certificate representing ten percent (10%) of the SCO Percentage
     Interest (the "Escrow Shares"). The Escrow Shares distributed to the Escrow
     Agent shall be held in escrow and shall be available to transfer to Caldera
     for certain damages as provided in Section 10. To the extent not
     transferred to Caldera for such damages, the Escrow Shares shall be
     released to SCO, all as provided in Section 10 and the Escrow Agreement.

          (c) Termination of Newco Options.  All shares of Common Stock
     underlying Newco Options assumed pursuant to Section 1.3(a)(iii) which
     terminate without being exercised by the Optionees shall be issued by
     Caldera to SCO on a quarterly basis.

     1.4  Contribution and Transfer of Contributed Stock and Contributed Assets.

          (a) Contribution and Transfer.  Subject to the terms and conditions of
     this Agreement and in consideration for the issuance by Newco of Newco
     Common Stock as provided above, the Contributing Companies shall at the
     Effective Time, for good and valuable consideration, the receipt and
     sufficiency of which are hereby acknowledged on behalf of each of the
     Contributing Companies, contribute and transfer and deliver to Newco or
     cause to be contributed, transferred and delivered to Newco, and at the
     Effective Time Newco shall accept the contribution and transfer from the

     Contributing Companies of all right, title and interest in and to the
     Contributed Stock and Contributed Assets. Notwithstanding the preceding,
     the Contributed Assets and Contributed Companies which are located outside
     of the United States shall be purchased and sold by and among the Newco and
     SCO entities located in such countries in exchange for stock or cash
     consideration as the parties shall agree before the Effective Time. Such
     payment shall be included within and shall not change the total amount of
     The SCO Percentage Interest and the Cash Consideration. The parties shall
     execute, or cause to be executed, Bills of Transfer relevant to their
     particular jurisdiction reflecting the transfer of any such Contributed
     Assets which shall reflect the purchase price allocation as agreed. Such
     amounts shall be reported as the purchase price for all foreign Tax
     reporting purposes in each relevant jurisdiction and no party shall have a
     position inconsistent therewith.

          (b) Excluded Assets.

             (i) Excluded Assets.  SCO is not selling and Caldera shall not
        acquire from SCO any of the following assets or any interest therein
        (collectively, the "Excluded Assets"):

                (A) any assets related solely to the SCO Retained Business;

                (B) any cash and cash equivalents and any accounts receivable
           (the "Cash Equivalents") of the Contributing Companies and the
           Contributed Companies;

                (C) those assets set forth on Exhibit 1.4(b).

             (ii) Net Cash Equivalents.  "Net Cash Equivalent" shall mean the
        net book value of any cash and cash equivalents held by any of the
        Contributed Companies, including but not limited to accounts receivable,
        accounts payable and third party debt obligations. To the extent the Net
        Cash Equivalents of any Contributed Company are or are expected to be
        positive as of the Effective Time, either SCO will withdraw that value
        from the Contributed Company at or before the Effective Time or Caldera
        will cause that value to be paid or credited to SCO at or promptly after
        the Effective Time. To the extent the Net Cash Equivalents of any
        Contributed Company are negative as of the Effective Time, SCO will pay
        or credit such amount to Caldera at or promptly after the Effective
        Time. The payment or credits will be treated as either a dividend by the
        Contributed Company or as an adjustment to the Cash Consideration as the
        parties may agree.

          (c) Assumption and Exclusion of Liabilities.

             (i) Assumed Liabilities.  As a result of the transfer to Newco of
        the Contributed Stock, Newco will as a matter of law own all of the
        outstanding equity capital of the Contributed Companies, which
        Contributed Companies and their respective Contributed Subsidiaries
        (collectively, the "Contributed Company Group") in turn shall remain
        liable for their respective Liabilities. In addition, subject to the
        terms and conditions of this Agreement, Newco (or a subsidiary of Newco
        designated by Newco and acceptable to SCO) shall, at the Effective Time,
        assume, and thereafter pay, perform and discharge when due those (and
        only those) Liabilities of the Contributing Companies and/or their
        direct and indirect subsidiaries (excluding the Liabilities of the
        Contributed Company Group, which are governed by the first sentence of
        this Section 1.4(c)(i)) that are expressly listed in the following
        subparagraphs of this Section 1.4(c)(i) (collectively, the "Assumed
        Liabilities") and no other Liabilities of the Contributing Companies
        whatsoever:

                (A) all Liabilities of the Contributing Companies under all
           Contributed Contracts;

                (B) all Liabilities of the Contributing Companies that are
           included in the Closing Group Account or that are listed on Exhibit
           1.4(c)(i)(B) attached hereto; and

                (C) those Tax liabilities for which Newco is responsible
           pursuant to Section 12 below.

             (ii) Excluded Liabilities Not Assumed.  Except for the Liabilities
        of the Contributed Company Group (which will remain the sole
        responsibility of the applicable member of the
                                       A-4
<PAGE>   253

        Contributed Company Group) and except for the Assumed Liabilities
        expressly described above in Section 1.4(c), Newco shall not assume,
        pay, perform or discharge, or otherwise have any obligation,
        responsibility or liability whatsoever for, any and all Liabilities of
        SCO or its direct and indirect subsidiaries (whether now existing or
        hereafter arising), and said companies shall retain, and shall be solely
        responsible and liable for paying, performing and discharging when due,
        all such Liabilities (collectively, the "Excluded Liabilities").

             (iii) Intercompany Accounts.  One or more Contributed Companies is
        likely to owe intercompany debt to SCO. The amount of any such
        intercompany debt remaining after payment by Newco to SCO of any Net
        Cash Equivalents will be treated as an Excluded Liability and will be
        cancelled by SCO.

          (d) Asset Contribution.  The SCO will, and will cause each of the
     other Contributing Companies to, take all actions and sign and deliver any
     and all instruments and documents (including Bills of Transfer for each
     relevant jurisdiction) reasonably necessary or appropriate to fully effect
     and perfect the transfer to Newco of any and all of the Contributed Stock
     and Contributed Assets held by either of them and any Contributed Contracts
     to which they are a party.

          (e) Unassignable Assets.  Notwithstanding any other provision of this
     Agreement or any of the Ancillary Agreements, to the extent that any of the
     Contributed Assets are not assignable or otherwise transferable by the
     Contributing Companies to Newco without the consent, approval or waiver of
     another party thereto or any third party (including any governmental
     agency), or if such assignment or transfer would constitute a breach
     thereof or of any other material contract binding upon the transferor or
     any of its Affiliates, or a violation of any applicable law, then neither
     this Agreement nor such Ancillary Agreements shall constitute an assignment
     or transfer (or an attempted assignment or transfer) thereof until such
     consent, approval or waiver of such party or parties has been duly
     obtained.

     With respect to each such Contributed Asset whose assignment or transfer to
Newco requires the consent, approval or waiver of another party thereto or any
third party, Newco and SCO shall cooperate and use their mutual reasonable,
commercial efforts to obtain such consent, approval or waiver of such other
party or parties or such third party to such assignment or transfer as promptly
as practicable prior to the Effective Time; and each agrees to supply relevant
information to such party or parties or such third party in order to facilitate
such objective. Notwithstanding the foregoing, nothing contained herein shall
obligate Newco or any Contributing Company to expend or pay any amount to third
parties to obtain any consents, approvals or waivers, or to make alternative
arrangements available; provided that where the Contributing Companies are
unable to effectively assign or otherwise transfer to Newco nor any Contributed
Asset without constituting a breach due to such lack of third party consent, the
Contributing Companies shall make available to Newco the net economic benefits
(such as inbound royalty payments, net of actual costs), if any, received by the
Contributing Companies from and after the Effective Time with respect to any
such Contributed Asset.

          (f) No Fraudulent Conveyance.  The Contributing Companies are not
     entering into this Agreement or any Ancillary Agreement with the intent to
     defraud, delay or hinder their respective creditors and the consummation of
     the transactions contemplated by this Agreement, and the Ancillary
     Agreements referenced in this Agreement will not have any such effect.
     Except for the Assumed Liabilities, the transfer of the Contributed Stock
     and Contributed Assets pursuant hereto will not give rise to any right of
     any creditor of the Contributing Companies to assert any claim whatsoever
     against Newco or any of the Contributed Stock and Contributed Assets in the
     hands of Newco or any of Newco's respective successors and assigns
     following the Effective Time which would have a Material Adverse Effect on
     Newco. SCO and its consolidated subsidiaries, taken as a group are Solvent,
     and will continue to be Solvent immediately following the transfer of the
     Contributed Stock and Contributed Assets pursuant to this Agreement.
     Neither SCO nor any of its consolidated subsidiaries nor any of the
     Contributed Stock and Contributed Assets is subject to, or the subject of,
     any Insolvency Proceeding or Insolvency Action. No writ of attachment,
     execution or similar process
                                       A-5
<PAGE>   254

     has been ordered, executed or filed against any of the Contributed Stock
     and Contributed Assets. There is not any reason to expect that any of the
     aforementioned actions, or any similar action, will take place or be taken,
     and there are no grounds for any of the aforementioned actions or like
     action. The parties agree that the securities issued by Newco to SCO and
     the Optionees and the other obligations on Newco's part to be performed
     under the terms of this Agreement and the Ancillary Agreements constitute
     full and fair equivalent consideration for the Contributed Stock and
     Contributing Assets exchanged therefor and the covenants, agreements and
     performances of the Contributing Companies under this Agreement and the
     Ancillary Agreements.

     1.5  Closing Matters.  Unless this Agreement has been terminated as
provided in Section 8 below, the closing of the transactions contemplated by
this Agreement (the "Closing") (i) will take place at the offices of Brobeck,
Phleger & Harrison LLP at Two Embarcadero Place, 2200 Geng Road, Palo Alto,
California 94303 on a date (the "Closing Date") and at a time to be mutually
agreed upon by the parties, which date shall be as soon as practicable after the
Caldera Stockholders Meeting and SCO Stockholders Meeting and, in any event, no
later than the third business day after all conditions to Closing set forth
herein shall have been satisfied or waived, unless another place, time and date
is mutually selected by SCO and Caldera and (ii) will take place concurrently
with the Effective Time.

     1.6  Dissenter's Rights.  It shall be the sole responsibility of SCO to
disclose any dissenter's rights which SCO stockholders have with respect to the
SCO Transaction; these rights shall be disclosed to Caldera in writing no later
than the date of filing the Proxy/Prospectus.

     1.7  Newco Plans.  Newco shall assume, effective as of the Closing, the
Caldera Plans, Caldera Stock Purchase Plan and non-plan grants and awards, as
amended through the Effective Time (collectively, the "Newco Plans"). Newco
shall also reserve a sufficient number of shares of Newco Common Stock for
issuance pursuant to the SCO Options assumed by Newco pursuant to Section
1.3(a)(ii) herein.

     1.8  Registration on Form S-8.  Newco will cause the Newco Common Stock
issuable upon exercise of outstanding awards under the Newco Plans or upon
exercise of the SCO Options assumed by Newco (collectively, the "Stock Rights")
and the shares reserved for issuance pursuant to future awards under the Newco
Plans to be registered on Form S-8 (the "Form S-8") promulgated by the SEC prior
to, but in no event later than, 10 days after the Effective Time and Newco will
use its reasonable best efforts to maintain the effectiveness of such
registration statement or registration statements for so long as any such Stock
Rights shall remain outstanding.

     1.9  Effects of the Caldera Merger.  At the Effective Time: (a) the
separate existence of Merger Sub will cease and Merger Sub will be merged with
and into Caldera, with Caldera being the surviving corporation of the Merger
(the "Caldera Surviving Corporation"), pursuant to the terms of this Agreement
and the Certificate of Merger; (b) the Certificate of Incorporation of the
Caldera Surviving Corporation shall be in the form attached as Exhibit A-1 to
the Certificate of Merger; (c) the Bylaws of Caldera immediately prior to the
Effective Time will be the Bylaws of the Caldera Surviving Corporation; (d) the
directors and officers of Caldera immediately prior to the Effective Time will
be the directors and officers of the Caldera Surviving Corporation; (e) each
share of the Common Stock of Merger Sub outstanding immediately prior to the
Effective Time will be converted into one share of Common Stock of the Caldera
Surviving Corporation; (f) each share of Caldera Common Stock, each Caldera
Option, and each Caldera Stock Purchase Plan Right outstanding immediately prior
to the Effective Time will be converted, as provided above in this Section
1.2(b). The Merger will, from and after the Effective Time, have all of the
effects provided by applicable law, including, without limitation, the Delaware
Law.

     1.10  Tax-Free Reorganization.  The parties adopt this Agreement (to the
extent it relates to the Merger) as a plan of reorganization and intend the
Merger to be a tax-free reorganization under Section 368(a)(1)(A) of the
Internal Revenue Code by virtue of the provisions of Section 368(a)(2)(E) of the
Internal Revenue Code. The Newco Common Stock issued in the Merger will be
issued solely in exchange for the Caldera Common Stock, and no other transaction
other than the Merger represents,

                                       A-6
<PAGE>   255

provides for or is intended to be an adjustment to the consideration paid for
the Caldera Common Stock. No consideration that could constitute "other
property" within the meaning of Section 356(b) of the Internal Revenue Code is
being transferred by Newco for the Caldera Common Stock in the Merger. The
parties shall not take a position on any tax return inconsistent with this
Section 1.10. In addition, Newco hereby represents, and will represent as of the
Effective Time, that it intends to continue Caldera's historic businesses or use
a significant portion of Caldera's business assets in a trade or business. None
of the parties shall cause a transaction, without offsetting compensation to the
other party, that would result in income to SCO under the Subpart F provisions
of the Internal Revenue Code.

     1.11  Tax-Free Section 351 Transaction.  The contribution and transfer of
the Contributed Stock and Contributed Assets to Newco in exchange for Newco
Common Stock, together with the Merger, are intended to constitute an exchange
within the meaning of Section 351 of the Internal Revenue Code. The Newco Common
Stock issued to SCO therein will be issued solely in exchange for the
Contributed Stock and Contributed Assets transferred in the SCO Transaction and
no consideration (other than the cash consideration) that could constitute other
property within the meaning of Internal Revenue Code Section 351(b) is being
transferred by Newco to SCO. The parties shall not take a position on any tax
return inconsistent with this Section 1.11.

     1.12  HSR Filings.  Caldera, SCO and Newco will as promptly as practicable
prepare and file the applicable notices and forms (if any) required to be filed
by them under the HSR Act or comparable laws of non-U.S. governmental entities,
and comply promptly with any appropriate requests from the Federal Trade
Commission, the United States Department of Justice or any other Governmental
Antitrust Authority for additional information and documentary material. The
parties hereto will not take any action that will have the effect of delaying,
impairing or impeding the termination of any waiting period or the receipt of
any required approvals of a Government Antitrust Authority. Without limiting the
generality of the parties' undertakings pursuant to this Section 1.12, the
parties shall use their reasonable best efforts to prevent the entry in a
judicial or administrative proceeding brought under any antitrust law by any
Governmental Antitrust Authority or any other party of any permanent or
preliminary injunction or other order that would make consummation of the SCO
Transaction or the Merger in accordance with the terms of this Agreement
unlawful under appropriate anti-trust laws or that would prevent or delay such
consummation as a consequence of such laws. Each party hereto shall promptly
inform the other of any material communication between such party and the
Federal Trade Commission, the Department of Justice or any other Governmental
Antitrust Authority regarding any of the transactions contemplated hereby. If
any party or any Affiliate of such party receives a request for additional
information or for documents or any material from any such Governmental
Antitrust Authority with respect to the transactions contemplated hereby, then
such party shall endeavor in good faith to make or cause to be made, as soon as
reasonably practicable and after consultation with the other parties, an
appropriate response in compliance with such request. Further, no written
materials shall be submitted by any party to the Federal Trade Commission, the
Department of Justice or any other Governmental Antitrust Authority in
connection with HSR Act compliance or the merger control regulations of any
other state or country, nor shall any oral communications be initiated with such
governmental entities by any party, without prior disclosure to and coordination
with the other parties and its counsel. Each party hereto will cooperate in
connection with reaching any understandings, undertakings or agreements (oral or
written) involving the Federal Trade Commission, the Department of Justice or
any other Governmental Antitrust Authority in connection with the transactions
contemplated hereby.

     1.13  Board of Directors and Officers of Newco; Newco Certificate of
           Incorporation and Bylaws.

(the "Prospectus/Proxy Statement") and any other documents required by the
Securities Act or the Exchange Act in connection with the Merger and the SCO
Transaction.

Effect on the Group Business. SCO has delivered to Caldera or its counsel
complete and correct copies of the charter documents of the Contributed

     under, or give rise to a right of termination, amendment, cancellation or
     acceleration of any obligation contained in, or the loss of any material

                                       A-9

     or (ii) require the affirmative vote of the holders of greater than a
     majority of the issued and outstanding capital stock of any member of the
     Contributing Companies or any member of the Contributed Company Group.

          (c) Governmental Consents.  Except (i) as set forth in Section 2.3(c)
     of the SCO Disclosure Letter; (ii) such filings, authorizations, orders and
     approvals as may be required under state takeover laws; (iii) such filings
     and notifications as may be necessary under the HSR Act; (iv) the filings,
     authorizations, orders, notifications, and approvals contemplated by this
     Agreement or the Ancillary Agreements; and (v) such other governmental or
     third party consents, filings, authorizations, orders and approvals which,
     if not obtained or made, would not have a Material Adverse Effect on Newco
     or have a material adverse effect on the ability of the Contributing
     Companies to consummate the transactions contemplated by this Agreement or
     the Ancillary Agreements, no consent, approval, order or authorization of,
     or registration, declaration or filing with, any governmental entity is
     required to be obtained by the Contributing Companies or any member of the
     Contributed Company Group in connection with the execution and delivery of
     this Agreement or the Ancillary Agreements by SCO or the performance of the
     Contributing Companies and the Contributed Companies of the respective
     obligations herein pertaining to such company.

     2.4  SEC Documents.

          (a) SEC Reports.  SCO has delivered to Caldera or its counsel correct
     and complete copies of the final version of each report, schedule,
     registration statement and definitive proxy statement filed by SCO with the
     SEC on or after July 1, 1995 with respect to the Group Business or the
     Group Assets (the "SCO SEC Documents"), which are the material documents
     (other than preliminary proxy material) that SCO was required to file with
     the SEC on or after July 1, 1995 with respect to the Group Business or the
     Group Assets. As of their respective dates or, in the case of registration
     statements, their effective dates, none of the SCO SEC Documents (including
     all exhibits and schedules thereto and documents incorporated by reference
     therein) contained any untrue statement of a material fact or omitted to
     state a material fact required to be stated therein or necessary in order
     to make the statements therein, in light of the circumstances under which
     they were made, not misleading as of such time of filing, and there is no
     requirement under the Securities Act or the Exchange Act, as the case may
     be, to have amended any such filing, except for such requirements as were
     fulfilled by the filing of such SCO SEC Documents, the SCO SEC Documents
     complied, when filed, in all material respects with the then applicable
     requirements of the Securities Act or the Exchange Act, as the case may be,
     and the rules and regulations promulgated by the SEC thereunder, and SCO
     has filed in all material respects all documents and agreements that were
     required to be filed as exhibits to the SCO SEC Documents.

          (b) SCO Financial Statements; Absence of Undisclosed Liabilities.  The
     audited consolidated financial statements dated as of and for the period
     ending September 30, 1999 and the unaudited consolidated financial
     statements dated as of and for the period ending June 30, 2000 of SCO and
     its consolidated subsidiaries (the "SCO Consolidated Financial Statements")
     complied as to form in all material respects with the then applicable
     accounting requirements and the published rules and regulations of the SEC
     with respect thereto, were prepared in accordance with GAAP applied on a
     consistent basis during the periods involved (except as may have been
     indicated in the notes thereto)

                                      A-10
<PAGE>   259

     and fairly present (subject, in the case of the unaudited statements, to
     normal year-end audit adjustments) the consolidated financial position of
     SCO and its respective consolidated subsidiaries as at the respective dates
     thereof and the consolidated results of its operations and cash flows for
     the respective periods then ended. SCO has no liabilities or obligations of
     any nature (matured or unmatured, fixed or contingent) which are,
     individually or in the aggregate, of a nature required to be disclosed on
     the face of a consolidated balance sheet for SCO and its consolidated
     subsidiaries prepared in accordance with GAAP and which would have a
     Material Adverse Effect on the Group Business, except for such liabilities
     or obligations as (i) were accrued or provided for in the consolidated
     balance sheet at June 30, 2000 included in the SCO Consolidated Financial
     Statements as of the date thereof (the "SCO Consolidated Financial
     Statements Balance Sheet Date") or (ii) are of a normally recurring nature
     and were incurred after the SCO Consolidated Financial Statements Balance
     Sheet Date in the ordinary course of business consistent with past
     practice. All liabilities and valuation accounts established and reflected
     in the SCO Consolidated Financial Statements are, to SCO's Knowledge,
     reasonably adequate. At the SCO Consolidated Financial Statements Balance
     Sheet Date, there were no material loss contingencies arising from the
     conduct of the business of SCO and its consolidated subsidiaries which are
     required to be provided for or disclosed, but are not provided for or
     disclosed, in the SCO Consolidated Financial Statements.

          (c) Group Financial Statements; Absence of Undisclosed
     Liabilities.  Attached as Schedule 2.4(c)(1) to the SCO Disclosure Letter
     are the audited combined financial statements of the Group Business dated
     as of and for the period ended June 30, 2000 including a combined balance
     sheets as of June 30, 2000 (the "2000 Group Balance Sheet") and a combined
     balance sheet for September 30, 1999 and 1998, together with combined
     statements of operations, cash flows, and Group Business equity for the two
     years and nine months in the period ended September 30, 1999 (collectively
     the "Group Financial Statements"). The Group Financial Statements comply in
     all material respects with the then applicable accounting requirements and
     rules and regulations of the SEC with respect thereto, and present fairly,
     in all material respects, the combined financial position of the Group
     Business as of September 30, 1999 and June 30, 2000, and the combined
     results of its operations and its cash flows for each of the two years and
     nine months in the period ended September 30, 1999, in conformity with
     GAAP. The Contributed Company Group and the Contributing Companies (with
     respect to the Group Business) have no Liabilities of any nature (matured
     or unmatured, fixed or contingent) which (i) are related to or arose in
     connection with the Group Business; (ii) individually or in the aggregate,
     are of a nature required to be recorded on the face of or disclosed in the
     notes to the Group Financial Statements; and (iii) are material to the
     Group Business taken as a whole, except for such Liabilities as (A) were
     accrued, provided for or disclosed in the Group Financial Statements or (B)
     are of a normally recurring nature and were incurred after June 30, 2000
     (the "Group Financial Statements Balance Sheet Date"), in the ordinary
     course of business consistent with past practice. All liabilities and
     valuation accounts established and reflected in the Group Financial
     Statements are, to SCO's Knowledge, reasonably adequate. To SCO's
     Knowledge, at the Group Financial Statements Balance Sheet Date, there were
     no material loss contingencies which are not properly provided for or
     disclosed in the Group Financial Statements.

     2.5  Disclosure; Information Supplied.  No representation or warranty made
by SCO in this Agreement, nor any final financial statement, certificate or
exhibit prepared and furnished or to be prepared and furnished by it, or its
representatives pursuant hereto or in connection with the transactions
contemplated hereby, contains any untrue statement of a material fact, or omits
to state a material fact necessary to make the statements or facts contained
herein or therein, taken as a whole, not misleading in light of the
circumstances under which they were furnished. None of the information supplied
or to be supplied by SCO for inclusion or incorporation by reference in the Form
S-4 and Prospectus/Proxy Statement will, at the time the information is supplied
contain, after giving effect to any supplement or amendment thereto, any untrue
statement of a material fact or omit to state any material fact required to be
stated therein or necessary to make the statements therein in light of the
circumstances under which they are made, not materially misleading.

     2.6  Compliance with Applicable Laws.  Except as disclosed in the SCO SEC
Documents filed prior to the date hereof, the Group Business is not being
conducted and no Contributed Company is in violation of any law, ordinance,
regulation, rule or order of any governmental entity where such violation would
have a Material Adverse Effect on the Group Business. Except as disclosed in the
SCO SEC Documents filed prior to the date hereof, neither SCO, any Contributing
Company, nor any member of the Contributed Company Group has been notified in
writing by any governmental entity that any investigation or review with respect
to the Contributed Companies or any of the Contributed Subsidiaries, any of the
Group Assets or the Group Business is pending or threatened, nor has any
governmental entity notified any of them in writing of its intention to conduct
the same. The Group Assets include all permits, licenses and franchises from
governmental entities required for the Conduct of the Group Business, except for
those whose absence would not have a Material Adverse Effect on the Group
Business and those which would terminate as a consequence of the SCO
Transaction.

     2.7  Litigation.  Except as would not reasonably be expected to have a
Material Adverse Effect on the Group Business or as set forth in Section 2.7 of
the SCO Disclosure Letter or as disclosed in the SCO SEC Documents, there is no
suit, action, arbitration, demand, investigation, claim or proceeding pending
or, to SCO's Knowledge, threatened against the Contributed Company Group, any of
the Contributing Companies or the Group Assets; nor is there any judgment,
decree, injunction, ruling or order of any governmental entity, statutory body
or arbitrator or settlement or compromise agreement outstanding against the
Contributed Company Group or any of the Contributing Companies or the Group
Assets. SCO has delivered or made available to Caldera or its counsel correct
and complete copies of all material correspondence prepared by its counsel for
SCO auditors in connection with the last two completed audits of SCO's Financial
Statements and the audit of the Group Financial Statements and any such
correspondence since the date of the last such audit. No member of the
Contributed Company Group and none of the Contributing Companies is a party to
any decree, judgment, order or arbitration award (or agreement entered into in
any administrative, judicial, investigative or arbitration proceeding with any
governmental authority) with respect to the Group Assets, Employees, or Group
Business that could reasonably be expected to have a Material Adverse Effect on
the Group Business. Except for violations as would not have a Material Adverse
Effect on the Group Business, none of the Contributing Companies nor any member
of the Contributed Company Group is in violation of any decree, judgement, order
or arbitration award that names such company, or any of such companies, as a
party or that otherwise, to SCO's Knowledge, involves such company or any of the
Group Assets, or in violation of any law, ordinance, statute, regulation or EU
directive or decree, order, judgment or ruling of any governmental authority to
which the Group Assets or the Contributed Stock are subject, including, without
limitation, laws, rules and regulations relating to occupational health and
safety, equal employment opportunities, fair employment practices, and sex,
race, religious, disability and age discrimination. To SCO's Knowledge, there is
no claim, action, suit, arbitration, mediation, investigation or other
proceeding of any nature pending or, threatened, at law or in equity, by way of
arbitration or before any court, tribunal, governmental department, statutory
body, commission, board or agency that: (i) may adversely affect, contest or
challenge any party's authority, right or ability to perform its obligations
under this Agreement or any of the Ancillary Agreements; (ii) challenges or
contests the Contributing Companies' or the Contributed Companies' right, title
or ownership of any of the Group Assets or the Contributed Stock or seeks to
impose an Encumbrance (other than a Group Permitted Encumbrance) on, or a
transfer of title or ownership of, any of the Group Assets or the Contributed
Stock; (iii) asserts that any action taken by any employee, consultant or
contractor of the Contributed Companies or Contributing Companies in connection
with the Group Business infringes or misappropriates any Intellectual Property
Rights of any third party; (iv) seeks to enjoin, prevent or hinder operation of
the Group Business; (v) seeks to enjoin, prevent, or hinder the consummation of
any of the transactions contemplated by this Agreement or any of the Ancillary
Agreements; (vi) would impair or have an adverse affect on Newco's right or
ability to use or exploit any of the Group Assets; (vii) involves or relates to
any potentially material claim against Contributing Companies or the Group
Assets by any creditor thereof; or (viii) involves any claim of fraudulent
conveyance or any similar claim, except in cases (ii), (iii), (iv), (vi) and
(vii) where such proceeding could not reasonably be expected to have a Material
Adverse Effect on Newco.

     2.8  ERISA and Other Compliance.

          (a) Section 2.8 of the SCO Disclosure Letter lists each employment,
     severance, compensation or other similar contract, arrangement or policy
     and each plan or arrangement (written or oral, contractual or
     discretionary) providing for insurance coverage (including any self-insured
     arrangements), workers' benefits, vacation benefits, severance benefits,
     disability or permanent health insurance benefits, death benefits,
     hospitalization or other medical benefits, retirement benefits, deferred
     compensation, profit-sharing, bonuses, commissions, stock options, stock
     purchase, phantom stock, stock appreciation, save as you earn or other
     forms of incentive compensation or post-retirement insurance, compensation
     or benefits for employees, consultants or directors (other than workers
     compensation, unemployment compensation and other government mandated
     programs) which both (A) is entered into, maintained or contributed to, as
     the case may be, by any member of the Contributed Company Group or any of
     the Contributing Companies, and (B) covers any Employee (collectively as
     the "Group Benefit Arrangements"). Each Group Benefit Arrangement
     maintained by any member of the Contributed Company Group has been
     maintained in compliance with its terms and with the requirements
     prescribed by any and all statutes, orders, rules and regulations which are
     applicable to such Group Benefit Arrangement except as would not have a
     Material Adverse Effect on the Group Business. Section 2.8(a) of the SCO
     Disclosure Letter also identifies each "employee benefit plan," as defined
     in Section 3(3) of ERISA ("Employee Benefit Plan"), in which any of the
     Employees participate (collectively, the "Group Employee Plans"). Copies of
     all Group Benefit Arrangements have been made available to Caldera or its
     counsel. All contributions or premiums currently due and payable with
     respect to any of the Group Employee Plans have been made as required under
     ERISA or have been accrued on the 2000 Group Balance Sheet or will be made
     prior to the Effective Time. Any Contributed Company Employee Plan intended
     to be qualified under Section 401(a) of the Code has either obtained from
     the Internal Revenue Service a favorable determination letter as to its
     qualified status under the Code, including all amendments to the Code
     effected by the Tax Reform Act of 1986, or has applied to the Internal
     Revenue Service for such a determination letter prior to the expiration of
     the requisite period under applicable Treasury Regulations or Internal
     Revenue Service pronouncements in which to apply for such determination
     letter and to make any amendments necessary to obtain a favorable
     determination or has been established under a standardized prototype plan
     for which an Internal Revenue Service opinion letter has been obtained by
     the plan sponsor and is valid as to the adopting employer. Each Contributed
     Company has made available upon Newco's request the most recent Internal
     Revenue Service determination or opinion letter issued with respect to each
     such Contributed Company Employee Plan, and nothing has occurred since the
     issuance of each such letter which could reasonably be expected to cause
     the loss of the tax-qualified status of any Contributed Company Employee
     Plan subject to Code Section 401(a).

          (b) None of the Group Employee Plans maintained by any of the
     Contributing Companies or any member of the Contributed Company Group (i)
     is a multiemployer plan, within the meaning of Section 3(37) or 4001(a)(3)
     of ERISA (a "Multiemployer Plan"), or a single employer pension plan,
     within the meaning of Section 4001(a)(15) of ERISA, for which Newco could
     incur liability under Section 4063 or 4064 of ERISA (a "Multiple Employer
     Plan"), or (ii) provides or promises to provide retiree medical or life
     insurance benefits except in connection with (a) benefit coverage mandated
     by applicable law, including without limitation, coverage provided pursuant
     to Section 4980B of the Code; (b) death or disability benefits under any of
     the Group Benefit Arrangements; (c) benefits arising in connection with a
     separation or severance program, plan or arrangement; and (d) life
     insurance benefits for any employee who dies while in service with any of
     the Contributing Companies or any member of the Contributed Company Group.
     None of the Contributing Companies or any member of the Contributed Company
     Group has incurred or will incur prior to or as of the Effective Time any
     material liability under, arising out of or by operation of Title IV of
     ERISA (other than liability for premiums to the Pension Benefit Guaranty
     Corporation arising in the ordinary course), including any liability in
     connection with (i) the termination or

                                      A-13
<PAGE>   262

     reorganization of any employee pension benefit plan subject to Title IV of
     ERISA or (ii) with withdrawal from any Multiemployer Plan or Multiple
     Employer Plan.

          (c) The appropriate Contributing Company or Contributed Company has
     timely provided, or will have provided prior to the Effective Time, to
     Employees entitled thereto all required notices and made coverage available
     pursuant to Section 4980B of the Internal Revenue Code and the Consolidated
     Omnibus Budget Reconciliation Act of 1985, as amended ("COBRA"), with
     respect to any "qualifying event" (as defined in Section 4980B(f)(3) of the
     Internal Revenue Code). The appropriate Contributing Company or Contributed
     Company will timely provide to Employees entitled thereto all required
     notices and make coverage available pursuant to Internal Revenue Code
     Section 4980B and COBRA with respect to any "qualifying event" (as defined
     in Section 4980B(f)(3) of the Internal Revenue Code) occurring prior to and
     including the Effective Time. No material Tax payable on account of Section
     4980B of the Internal Revenue Code has been incurred by the Contributing
     Companies or any of the Contributed Companies with respect to any current
     Employees (or its beneficiaries).

          (d) The consummation of the transactions contemplated by this
     Agreement will not (i) entitle any current or former employee or other
     service provider of the Contributed Companies or the Contributing Companies
     to severance benefits or any other payment or (ii) accelerate the time of
     payment or vesting (including any SCO Option or unvested shares of SCO
     Common Stock), or increase the amount of compensation due any such employee
     or other service provider. No payment or benefit payable or which may
     become payable by any of the Contributed Companies or by any of the
     Contributing Companies with respect to any current or former employee, or
     other current or former service provider shall constitute a "parachute
     payment" (as defined in Section 280G(b)(2) of the Internal Revenue Code).
     Within five (5) business days following the date of this Agreement, SCO
     shall identity in Section 2.8 of the SCO Disclosure Letter all persons on
     the Section 11.1 Schedule who SCO reasonably believes are, as of the date
     of this Agreement, "disqualified individuals" (within the meaning of
     Section 280G of the Code and the regulations promulgated thereunder) with
     respect to the Contributing Companies or the Contributed Companies. Within
     five (5) business days prior to the expected Closing Date, SCO shall revise
     Section 2.8 of the SCO Disclosure Letter to reflect any additional
     information which SCO reasonably believes would impact the determination of
     persons who are of such date "disqualified individuals" (within the meaning
     of Section 280G of the Code and the regulations promulgated thereunder).

          (e) To SCO's Knowledge, no Employee who is a key developer of a Group
     Product is subject to any agreement, obligation, order or other legal
     hindrance that impedes or might impede such Employee from devoting his or
     her full business time to the affairs of Newco after the Effective Time.

          (f) None of the Contributed Companies are indebted to any executive
     officer or director of any such Contributed Company, whether by loan,
     advance or otherwise, other than for salaries accrued but not yet payable
     and reimbursable out-of-pocket expenses incurred in the ordinary course of
     business consistent with past practice and not yet payable, nor, except as
     described in Section 2.8(f) to the SCO Disclosure Letter or except as
     disclosed in the 2000 Group Balance Sheet or the SCO SEC Documents, is any
     officer, director, employee or shareholder so indebted to any of SCO or any
     of the Contributed Companies, nor does any Employee have any right to force
     SCO or any Contributing Company to repurchase any stock.

          (g) The Contributed Company Group and the Contributing Companies are
     in compliance in all material respects with all currently applicable laws
     and regulations, domestic or foreign, respecting employment, discrimination
     in employment, terms and conditions of employment, wages, hours,
     governmental and administrative contribution requirements and occupational
     safety and health and employment practices, and is not engaged in any
     unfair labor practice with respect to the Employees in each of the
     countries where the Contributed Company Group and the Contributing
     Companies have employees. The Contributed Company Group and the
     Contributing Companies have withheld all amounts required by law or by
     agreement to be withheld from the wages, salaries, and other payments

                                      A-14
<PAGE>   263

     to Employees; and is not liable for any arrears of wages or any taxes or
     any penalty for failure to comply with any of the foregoing. The
     Contributing Company Group and the Contributing Companies are not liable
     for any payment to any trust or other fund or to any governmental or
     administrative authority, with respect to unemployment compensation
     benefits, social security or other benefits or obligations for Employees
     (other than routine payments to be made in the normal course of business
     and consistent with past practice). There are no pending claims against the
     Contributed Company Group and the Contributing Companies under any workers
     compensation plan, policy, statute or regulation or any other plan or
     policy to which the Contributed Company Group and/or any Contributing
     Company are parties or for long term disability. There are no controversies
     or disputes pending or, to the knowledge of the Contributed Company Group
     and the Contributing Companies, threatened, between the Contributed Company
     Group and the Contributing Companies and any of their respective employees,
     which controversies have or could reasonably be expected to result in an
     action, suit, proceeding, claim, arbitration or investigation before any
     agency, court or tribunal, foreign or domestic. None of the Contributed
     Company Group or the Contributing Companies is a party to any collective
     bargaining agreement or other labor union contract nor does the Contributed
     Company Group and the Contributing Companies know of any activities or
     proceedings of any labor union to organize any such Employees. To SCO's
     knowledge, no Employees of the Contributed Company Group and the
     Contributing Companies are in violation of any term of any employment
     contract, patent disclosure agreement, enforceable noncompetition
     agreement, or any enforceable restrictive covenant to a former employer
     relating to the right of any such Employee to be employed by SCO because of
     the nature of the business conducted or presently proposed to be conducted
     by SCO or to the use of trade secrets or proprietary information of others.

          (h) Section 2.8(h) of the SCO Disclosure Letter lists, with respect to
     any member of the Contributed Company Group or any of the Contributing
     Companies, all employee benefit plans, programs or arrangements for
     employees who work outside the United States ("Foreign Employee Plans").
     Except as disclosed in Section 2.8(h) of the SCO Disclosure Letter, no
     member of the Contributed Company Group or any of the Contributing
     Companies maintains any Foreign Employee Plans other than those required by
     applicable law. SCO has furnished or made available to Caldera a copy of
     each of the Foreign Employee Plans. Each Foreign Employee Plan has been
     operated and administered in accordance with its terms and applicable laws,
     rules and regulations.

     2.9  Absence of Certain Changes or Events.  Except as disclosed in Section
2.9 of the SCO Disclosure Letter, since the Group Financial Statements Balance
Sheet Date there has not occurred:

          (a) any change or event which could reasonably be expected to have a
     Material Adverse Effect on the Group Business;

          (b) any amendments or changes in the Certificate of Incorporation or
     Bylaws (or similar or equivalent governing documents on each relevant
     jurisdiction) of any member of the Contributed Company Group;

          (c) any damage, destruction or loss to or of the Group Assets not
     covered by insurance, which would have a Material Adverse Effect on the
     Group Business;

          (d) any redemption, repurchase or other acquisition of shares of any
     member of the Contributed Company Group, or any declaration, setting aside
     or payment of any dividend or other distribution by any Contributing
     Company or any member of the Contributed Company Group to any entity other
     than a member of the Contributed Company Group (whether in cash, stock or
     property) of the Group Assets or any proceeds generated by the conduct of
     the Group Business;

          (e) any material increase in or modification of the compensation or
     benefits payable, or to become payable, by the Contributed Companies to the
     Employees, except in the ordinary course of the business, consistent with
     past practice or except as necessary to respond to third party solicitation
     of Employees,

                                      A-15
<PAGE>   264

          (f) other than as required by applicable statute or governmental
     regulation, any material increase in or modification of any Group Benefit
     Arrangement (including, but not limited to, the granting of stock options,
     the acceleration of the vesting schedules in effect for outstanding stock
     options, restricted stock awards or stock appreciation rights) that will
     become binding upon Newco upon consummation of the transactions
     contemplated herein, for or with respect to any of the Employees, other
     than increases or modifications occurring after the date hereof, which are
     authorized pursuant to Section 4.3 below;

          (g) any sale of a material amount of the Group Assets, or any
     acquisition by any member of the Contributed Company Group of a material
     amount of assets;

          (h) any stock/share capital being allotted or issued or agreed to be
     allotted or issued or any alteration in any term of any outstanding capital
     stock or rights to acquire capital stock, share or loan capital of any
     member of the Contributed Company Group, including, but not limited to,
     acceleration of the vesting or any change in the terms of any outstanding
     stock options;

          (i) (A) any incurrence, assumption or guarantee by any member of the
     Contributed Company Group of any debt of any person, other than any member
     of the Contributed Company Group, for borrowed money in an amount exceeding
     $250,000 in the aggregate; (B) issuance or sale by any member of the

Governmental Permits is in full force and effect and is not subject to any
breach or default thereunder by any Contributing Company or any member of the
Contributed Company Group or, to SCO's Knowledge, any other party thereto,

     2.12  No Defaults.  Notwithstanding Section 1.4(c), there exists no event
(including closing of the transactions contemplated by this Agreement),
condition or occurrence which, after notice or lapse of time, or both, would
constitute a default by the Contributing Companies who are parties thereto under
any Contributed Contract in any manner which would have a Material Adverse
Effect on the Group Business.

     2.13  Certain Agreements.  Neither the execution and delivery of this
Agreement or the Ancillary Agreements, nor the consummation of the transactions
contemplated hereby and thereby, will, (i) result in any payment in an amount
exceeding $50,000 individually or $250,000 in the aggregate (including, without
limitation, severance, unemployment compensation, golden parachute, bonus or

     2.14  Taxes.  SCO and each of its subsidiaries have properly completed and
timely filed, or caused to be properly completed and timely filed, all Tax
returns required to be filed by them and have paid, or caused to be paid, all
Taxes that are shown on such Tax returns as due and payable. All Taxes of SCO
and its subsidiaries for all periods through June 30, 2000, have been fully paid
(except for Taxes that are adequately provided for or reflected in the SCO
Consolidated Financial Statements). Since June 30, 2000, no material Tax
liability has been assessed, or is, to SCO's Knowledge, proposed to be assessed,
incurred or accrued (other than liabilities for Taxes arising in the ordinary
course of business) against SCO or any of its subsidiaries. To SCO's Knowledge,
neither SCO nor any of its subsidiaries has received any notification that any
material issues have been raised (or are currently pending) by the Internal
Revenue Service or any other taxing authority, including, without limitation,
any sales tax authority, in connection with any of the Tax returns referred to
in the first sentence of this Section 2.14, and no unexpired waivers of statutes
of limitations have been given or requested with respect to Tax returns or Taxes
of SCO and its consolidated subsidiaries. No taxing authority is currently
conducting an audit or investigation of any of the aforesaid Tax returns or to
SCO's Knowledge is about to conduct such an audit or investigation with respect
to such Tax returns. Any deficiencies asserted or assessments (including
interest and penalties) made as a result of any examination by the Internal
Revenue Service or by appropriate national, state, provincial or departmental
authorities of the Tax returns with respect to SCO and any of its subsidiaries
have been paid or adequately provided for in the SCO Consolidated Financial
Statements, and, to SCO's Knowledge, no proposed (but unassessed) additional
Taxes have been asserted and no Tax liens have been filed against SCO or any of
its subsidiaries other than for Taxes not yet due and payable. Neither SCO nor
any member of the Contributed Company Group (i) has made an election to be
treated as a "consenting corporation" under Section 341(f) of the Internal
Revenue Code or (ii) is a "personal holding company" within the meaning of
Section 542 of the Internal Revenue Code;

          (b) If any of the capital assets of the UK Contributed Companies were
     disposed of for a consideration equal to the book value of that asset in or
     adopted for the purposes of the SCO Consolidated Financial Statements, no
     liability to corporation tax on chargeable gains or balancing charge under
     the Capital Allowances Act 1990 would arise (for this purpose there shall
     be disregarded any relief or allowance available to the UK Contributed
     Companies (other than amounts falling to be deducted from the consideration
     receivable under section 38 of the TCGA)). No chargeable gain or balancing
     charge would arise on the disposal by the Contributing Company of any asset
     acquired since the SCO Consolidated Financial Statements Date for a
     consideration equal to the consideration actually given for the acquisition
     of such asset (disregarding any indexation relief);

          (c) The UK Contributed Companies have not entered into any
     transaction, contract or arrangement, whether verbal or written and whether
     made within or outside the UK, under which it has or may become liable to
     pay or to account for stamp duty or stamp duty reserve tax and which
     liability remains unsatisfied;

     guarantee, covenant, charge or other agreement under which they have agreed
     to, or can be procured to pay a sum equivalent to or by reference to
     another person's liability to Tax, nor do any other circumstances exist
     whereby the Contributed Companies would have to make such a payment;

          (e) All reliefs assumed as an asset or otherwise taken into account in
     the SCO Consolidated Financial Statements are available to be utilized by
     the UK Contributed Companies at Closing;

          (f) The UK Contributing Companies have never been members of a group
     of companies for UK tax purposes other than a group comprising only the UK
     Contributing Companies;

          (g) The provisions of Part XV of the UK Value Added Tax Regulations
     1995 (capital goods scheme) do not apply to any of the UK Contributed
     Assets;

          (h) No election has been nor will before Closing be made pursuant to
     paragraph 2 of Schedule 10 to the Value Added Tax Act 1994 ("VATA 1994") in
     relation to any of the UK Properties or any part of any of them;

     the UK Contributed Assets have been paid in full, and none of the UK
     Contributed Assets is liable to confiscation, forfeiture or distress;

          (j) All documents (other than those which have ceased to have any
     legal effect) to which the UK Contributed Companies or any member of the UK
     Contributed Companies group of companies is a party and which are material
     to the title of the UK Contributed Assets have been duly stamped and no
     such documents which are outside the UK would attract stamp duty if they
     were bought into the UK;

          (k) All National Insurance and sums payable by the UK Contributed
     Companies to the UK Inland Revenue under the PAYE system have been duly and
     properly paid. Proper records have been maintained in respect of all such
     matters.

          (l) There is no unsatisfied liability to capital transfer tax or
     inheritance tax attached or attributable to any of the UK Contributed
     Assets and none of the UK Contributed Assets are, or are likely to be,
     subject to an Inland Revenue charge as mentioned in Section 237 of the
     Inheritance Tax Act 1984; and

          (m) No person is liable to capital transfer tax or inheritance tax
     attributable to the value of any of the UK Contributed Assets in
     consequence no person has the power under Section 212 of the Inheritance
     Tax Act 1984 to raise the amount of such tax by the sale or mortgage of or
     by a charge on any of the UK Contributed Assets.

     2.15  Intellectual Property.

          (a) The Contributed Companies and, insofar as it relates to the Group
     Business, the Contributing Companies own, or have the right to use, sell or
     license such Intellectual Property Rights as are necessary or required for
     the Conduct of the Group Business (such Intellectual Property Rights being
     hereinafter collectively referred to as the "SCO IP Rights") and such
     ownership or rights to use, sell or license are reasonably sufficient for
     the Conduct of the Group Business, except for any failure to own or have
     the right to use, sell or license that would not have a Material Adverse
     Effect on the Group Business.

          (b) All SCO IP Rights are owned free and clear of any Encumbrances
     (other than Group Permitted Encumbrances).

          (c) The execution, delivery and performance of this Agreement and the
     consummation of the transactions contemplated hereby will not constitute a
     material breach of any material instrument or material agreement in respect
     of any SCO IP Rights licensed by or to any Contributing Company or
     Contributed Company (the "SCO IP Rights Agreements"), will not cause the
     forfeiture or termination
                                      A-19
<PAGE>   268

     or give rise to a right of forfeiture or termination of any SCO IP Right or
     materially impair the right of Newco to use, sell or license any SCO IP
     Right or portion thereof (except where such breach, forfeiture, termination
     or impairment would not have a Material Adverse Effect on the Group
     Business).

          (d) There are no royalties, honoraria, fees or other payments payable
     by any member of the Contributed Company Group or any Contributing Company
     to any person by reason of the ownership, use, license, purchase, sale or
     disposition or acquisition of any of the SCO IP Rights in an amount
     exceeding $100,000 in any one year.

          (e) To SCO's Knowledge, no third party is infringing or
     misappropriating any of the SCO IP Rights.

          (f) To SCO's Knowledge, (i) neither the manufacture, marketing,
     license, sale or intended use of any Group Product violates any license or
     agreement relating thereto or infringes any Intellectual Property Right of
     any other party, (ii) there is no pending or threatened claim or litigation
     contesting the validity, ownership or right to use, sell, license or
     dispose of any SCO IP Right, and (iii) no third party has notified the
     Contributing Companies or the Contributed Company Group that any SCO IP
     Right, or the proposed use, sale, license or disposition thereof, conflicts
     or will conflict with the rights of any other party, nor is there any basis
     therefor, except for any violations, infringements, claims or litigation
     that would not have a Material Adverse Effect on the Group Business.

          (g) The Contributing Companies and the Contributed Company Group have
     taken reasonable and practicable steps designed to safeguard and maintain
     the secrecy and confidentiality of, and its proprietary rights in, all
     material trade secrets or other confidential information constituting SCO
     IP Rights. To SCO's Knowledge, no current or prior officers, employees or
     consultants of the Contributing Companies or the Contributed Company Group
     claim an ownership interest in or have a lien on any SCO IP Rights or any
     form of compensation out of the ordinary course of business as a result of
     having been involved in the development of such property while so employed,
     or retained, or otherwise. To SCO's Knowledge, all development employees of
     the SCO IP Rights, and all other officers, employees and consultants of the
     Contributed Company Group have executed and delivered an agreement
     regarding the protection of proprietary information and the assignment to
     his/her employer or principal of the SCO IP Rights arising from the
     services performed by such persons, except where this absence of such
     agreement would not have a Material Adverse Effect on the Group Business.

          (h) Section 2.15(h) of the SCO Disclosure Letter lists each license,
     sublicense, agreement or other permission pursuant to which SCO or the
     Contributed Business Group is entitled to use third party IP Rights
     (excluding shrink wrap licenses to commercially available software sold at
     retail) as of the date hereof, the absence of which would have a Material
     Adverse Effect on the Group Business that a third party owns and that SCO
     or the Contributed Business Group uses pursuant to a license, sublicense,
     agreement or other permission, and describes and identifies such license,
     sublicense, agreement or other permission (excluding shrink wrap licenses
     to commercially available software sold at retail). Such license,
     sublicense, agreement or permission covering the item is legal, valid,
     binding, enforceable and in full force and effect and will continue to be
     legal, valid, binding, enforceable and in full force and effect on
     identical terms to Newco's benefit immediately following the Effective
     Time, except where it would not have a Material Adverse Effect on Newco,
     and such license, sublicense, agreement or permission does not restrict the
     ability to market any material Group Product in any material jurisdiction
     or with respect to any material market or industry, and neither SCO nor the
     Contributed Company Group is in breach or default of any such license,
     sublicense, agreement or permission in a manner which would have a Material
     Adverse Effect on the Group Business. No person other than the Contributing
     Companies holds any license or other right to manufacture, modify, or
     create derivative works of any of the Group Products, other than OEM
     agreements that would not have a Material Adverse Effect on the Group
     Business. No person (other than Newco) will be or become entitled to
     receive a copy of source code of any software included among the Group

                                      A-20
<PAGE>   269

     Assets as a result of this Agreement, any Ancillary Agreement or any other
     agreement or transaction contemplated by this Agreement. Except as
     disclosed in Section 2.15(h) of the SCO Disclosure Letter, to SCO's
     Knowledge, no person holds or has been granted access to any copy of source
     code of any software included among the Group Assets unless such person has
     agreed in writing (i) to hold such source code in confidence and take
     reasonable steps to preserve the secrecy of such source code, and (ii) not
     to use such source code for any purpose except (A) to support such person's
     internal use of such source code or (B) to modify such source code solely
     for the purpose of internally using such modifications. None of SCO or the
     Contributed Companies have knowingly taken or knowingly failed to take any
     action that, directly or indirectly, has caused any Intellectual Property
     Rights in source code of material Group Products to enter the public
     domain, such as would have a Material Adverse Effect on the Group Business.

     2.16  Fees and Expenses.  Except for the fees and expenses set forth in
SCO's engagement letter with Chase HQ, a copy of which has been provided to
Caldera, no member of the Contributed Company Group and none of the Contributing
Companies has paid or become obligated to pay any fee or commission to any
broker, finder or intermediary in connection with the transactions contemplated
by this Agreement and the Ancillary Agreements.

     2.17  Insurance.  The members of the Contributed Company Group maintain
fire and casualty, general liability, business interruption, directors and
officers, product liability and sprinkler and water damage insurance that they
believe to be reasonable for its respective businesses.

     2.18  Ownership of Property.  Except for Group Permitted Encumbrances, the
Contributed Company Group and the Contributing Companies own, or at the
Effective Time will own, the Contributed Company Assets, free and clear of all
Encumbrances. All real and personal property included in the Group Assets is in
good working condition and suitable for its intended use, subject to ordinary
wear and tear. To SCO's Knowledge, no member of the Contributed Company Group is
in violation in any material respect with any zoning, building or safety
ordinance, regulation or requirement or other law or regulation applicable to
the operation of its respective owned or leased properties.

     2.19  Environmental Matters.

          (a) During the period that the Contributed Companies and the
     Contributing Companies (with respect to the Group Assets or any real estate
     leased thereunder) have leased or owned its respective properties or owned
     or operated its respective facilities, there have been, to SCO's Knowledge,
     no disposals, releases or threatened releases of Hazardous Materials on,
     from, under or about such properties or facilities which would cause a
     Material Adverse Effect on Newco. To SCO's Knowledge there is no presence,
     disposals, releases or threatened releases of Hazardous Materials on, from,
     under or about any of such properties or facilities, which may have
     occurred prior to said Member of the Contributed Company Group or the
     Contributing Companies (with respect to the Group Assets or any real estate
     leased thereunder) having taken possession of any of such properties or
     facilities, where such Hazardous Materials would cause a Material Adverse
     Effect on Newco.

          (b) None of the properties or facilities which are Group Assets is or
     has been the subject of an Environmental Violation, which would cause a
     Material Adverse Effect on Newco. During the time that a Member of the
     Contributed Company Group or the Contributing Companies (with respect to
     the Group Assets or any real estate leased thereunder) owned or leased its
     respective properties and facilities, none of said companies and, to SCO's
     Knowledge, no third party, used, generated, manufactured or stored on,
     under or about such properties or facilities or transported to or from such
     properties or facilities any Hazardous Materials (except those Hazardous
     Materials associated with general office use or janitorial supplies) in a
     manner which would result in a Material Adverse Effect on Newco.

          (c) During the time that any member of the Contributed Company Group
     and the Contributing Companies (with respect to the Group Assets or any
     real estate leased thereunder) owned or leased its respective properties
     and facilities, to SCO's Knowledge, there has been no litigation brought or
                                      A-21
<PAGE>   270

     threatened against any such Company, or any settlement reached by any such
     Company with, any party or parties concerning the presence, disposal,
     release or threatened release of any Hazardous Materials on, from or under
     any of such properties or facilities or relating to any alleged
     Environmental Violation, except for litigation or settlement which would
     not have a Material Adverse Effect on Newco.

     2.20  Interested Party Transactions.  Except as disclosed in the SCO SEC
Documents, no officer or director of a Contributing Company, or any "affiliate"
or "associate" (as those terms are defined in Rule 405 promulgated under the
Securities Act) of a Contributing Company has, either directly or indirectly, a
material interest in: (i) any person or entity which purchases from or sells,
licenses or furnishes to the Contributed Company Group in connection with the
Group Business, any goods, property, technology or intellectual or other
property rights or services; or (ii) any Contributed Contract; which, in the
case of either subpart (i) or (ii) would have a Material Adverse Effect on the
Group Business.

     2.21  Fairness Opinion.  SCO's Board of Directors has received an opinion
dated as of the date hereof from Chase HQ to the effect that, as of the date
hereof, the terms of the transactions contemplated by this Agreement and the
Ancillary Agreements are fair to SCO from a financial point of view.

     2.22  Title to and Condition and Sufficiency of Group Assets.  A member of
the Contributed Company Group and/or a Contributing Company owns or at the
Closing will own the Group Assets and have good and marketable title thereto,
free and clear of all Encumbrances whatsoever, other than the Group Permitted
Encumbrances. The Group Assets transferred to Newco constitute all assets,
properties, rights, contracts and Intellectual Property Rights that are
necessary or required for the Conduct of the Group Business as currently
conducted, without (i) the need to purchase, license or acquire any other
material asset or property; (ii) violating any contractual rights of any third
party; or (iii) infringing, misappropriating or misusing any software or
Intellectual Property Rights of any third party, except for such assets,
properties, rights, contracts, software and Intellectual Property Rights, the
absence of which, individually or in the aggregate, would not have a Material
Adverse Effect on the Group Business. Title to all Group Assets is freely
transferable to and, with respect to the Contributed Assets and Contributed
Stock, will be transferred to Newco free and clear of all Encumbrances, other
than Group Permitted Encumbrances. Such transfer of the Contributed Assets and
Contributed Stock can occur without obtaining the consent or approval of any
person, except where the failure to transfer the Group Asset would not have a
Material Adverse Effect on Newco. At the Closing, the Contributing Companies
will contribute, transfer and deliver to Newco all right, title and interest in
and to all Contributed Assets and Contributed Stock, free and clear of all
Encumbrances, other than Group Permitted Encumbrances.

     2.23  No Restrictive Agreements.  Other than this Agreement and the
Ancillary Agreements, neither any Member of the Contributed Company Group nor
SCO nor any of the Group Assets is bound, or materially and adversely affected
by, any judgment, injunction, order, decree, contract, covenant or agreement
(noncompete or otherwise) that restricts or prohibits (or purports to restrict
or prohibit) the Conduct of the Group Business or from competing for the sale of
the Group Products anywhere in the world (including without limitation any
contracts, covenants or agreements restricting the geographic area in which the
Group Business may sell, license, market, distribute or support any Group
Products) or restricting the markets, customers or industries that Newco may
address after the Closing in the Conduct of the Group Business (collectively,
"Group Restrictive Agreements"), in a manner, in any of the foregoing cases,
which will have a Material Adverse Effect on Newco.

     2.24  Supplier and Customer Relationships.  To SCO's Knowledge, (i) the
Contributed Company Group has good commercial working relationships with the
customers for the Group Business, and (ii) since January 1, 2000 no customer of,
or supplier to the Group Business has cancelled or otherwise terminated any
material relationship concerning the Group Business with the Contributed Company
Group or SCO (with respect to the Group), or materially decreased or limited its

          (a) Product Quality, Warranty Claims.  All Group Products
     manufactured, sold, licensed, leased or delivered in connection with the
     Group Business conform in all material respects to applicable contractual
     commitments, express and implied warranties, and, to SCO's Knowledge, there
     is no material Liability (nor any basis for any present or future action,

     thereof or other damages in connection therewith, except for such
     conformance as would not have a Material Adverse Effect on Newco.

          (b) Inventory.  To SCO's Knowledge, its inventories recorded on the
     2000 Group Balance Sheet consist primarily of materials used in operating
     system software products, related supplies and packaging materials, all of
     which are merchantable, fit for the purpose for which they were procured or
     manufactured, and are in a condition and quantity usable in the ordinary
     course of business and to SCO's Knowledge, none of these inventories are
     obsolete, damaged or defective, except in each case where the failure of
     these inventories to be so would not have a Material Adverse Effect on
     Newco or where a sufficient provision with respect to the possibility of
     such failure is included in the 2000 Group Balance Sheet.

     The affirmative vote of a majority of the votes that holders of the

     3.4  SEC Documents.

          (a) SEC Reports.  Caldera has delivered to SCO or its counsel correct
     and complete copies of the final version of each report, schedule,
     registration statement and definitive proxy statement filed by Caldera with
     the SEC on or after March 20, 2000 (the "Caldera SEC Documents"), which are
     the material documents (other than preliminary material) that Caldera was
     required to file with the SEC on or after March 20, 2000 with respect, in
     whole or in part, to Caldera or the Caldera Assets. As of their respective
     dates or, in the case of registration statements, their effective dates,
     none of the Caldera SEC Documents (including all exhibits and schedules
     thereto and documents incorporated by reference therein) contained any
     untrue statement of a material fact or omitted to state a material fact
     required to be stated therein or necessary in order to make the statements
     therein, in light of the circumstances under which they were made, not
     misleading, and there is no requirement under the Securities Act or the
     Exchange Act, as the case may be, to have amended any such filing. The
     Caldera SEC Documents complied, when filed, in all material respects with
     the then applicable requirements of the Securities Act or the Exchange Act,
     as the case may be, and the rules and regulations promulgated by the SEC
     thereunder. Caldera has filed all documents and agreements that were
     required to be filed as exhibits to the Caldera SEC Documents.

          (b) Caldera Financial Statements; Absence of Undisclosed
     Liabilities.  The audited consolidated financial statements, dated as of
     and for the period ended, October 31, 1999, and the unaudited consolidated
     financial statements, dated as of and for the period ending April 30, 2000,
     of Caldera and its consolidated subsidiaries ("Caldera Financial
     Statements") complied as to form in all material respects with the then
     applicable accounting requirements and the published rules and regulations
     of the SEC with respect thereto, were prepared in accordance with GAAP
     applied on a consistent basis during the periods involved (except as may
     have been indicated in the notes thereto) and fairly present (subject, in
     the case of the unaudited statements, to normal year-end audit adjustments)
     the consolidated financial position of the Caldera Group as at the
     respective dates thereof and the consolidated results of its operations and
     cash flows for the respective periods then ended. Caldera has no
     liabilities or obligations of any nature (matured or unmatured, fixed or
     contingent) which are, individually or in the aggregate, of a nature
     required to be disclosed on the face of a consolidated balance sheet for
     Caldera and its consolidated subsidiaries prepared in accordance with GAAP
     and which are material to the Caldera Business, except for such liabilities
     or obligations as (i) were accrued or were provided for in the consolidated
     balance sheet dated April 30, 2000 included in the Caldera Financial
     Statements as of the date thereof (the "Caldera Financial Statements
     Balance Sheet Date") or (ii) are of a normally recurring nature and were
     incurred after the Caldera Financial Statements Balance Sheet Date in the
     ordinary course of business consistent with past practice. All liabilities
     and valuation accounts established and reflected in the Caldera Financial
     Statements are to Caldera's Knowledge reasonably adequate. At the Caldera
     Financial Statements Balance Sheet Date, there were no material loss
     contingencies which are not adequately provided for in the Caldera
     Financial Statements.

     3.5  Disclosure; Information Supplied.  No representation or warranty made

exhibit prepared and furnished or to be prepared and furnished by Caldera or its
respective representatives pursuant hereto or in connection with the
transactions contemplated hereby, when taken together, contains any untrue
statement of a material fact, or omits to state a material fact necessary to
make the statements or facts contained herein or therein, taken as a whole not
misleading in light of the circumstances under which they were furnished. None
of the information supplied or to be supplied by Caldera for inclusion or
incorporation by reference in the Form S-4 and Prospectus/Proxy Statement will,
at the time the information is supplied contain, after giving effect to any
supplement or amendment thereto, no untrue statement of a material fact or omit
to state any material fact required to be stated therein or necessary to make
the statements therein, in light of the circumstances under which they are made,
not materially misleading. The Prospectus/Proxy Statement will in all material
respects comply as to form with the provisions of the Exchange Act and the rules
and regulations promulgated by the SEC thereunder.

Caldera's auditors in connection with the last two completed audits of Caldera's
financial statements and any such correspondence since the date of the last such

arbitration award (or agreement entered into in any administrative, judicial or
arbitration proceeding with any governmental authority) with respect to the
Caldera Assets, Caldera Employees, or the Caldera Business that could reasonably
be expected to have a Material Adverse Effect on Caldera. Except for violations
as would not have a Material Adverse Effect on Caldera, none of the members of
the Caldera Group is in violation of any decree, order or arbitration award that
names such company, or any of such companies, as a party or that otherwise, to
Caldera's Knowledge, involves such company or any of such company's assets, or
of any law, ordinance, statute, or governmental authority to which the Caldera
Assets are subject, including, without limitation, laws, rules and regulations
relating to occupational health and safety, equal employment opportunities, fair
employment practices, and sex, race, religious and age discrimination. There is
no claim, action, suit, arbitration, mediation, investigation or other
proceeding of any nature pending or, to Caldera's Knowledge, threatened, at law
or in equity, by way of arbitration or before any court, governmental
department, commission, board or agency that: (i) may adversely affect, contest
or challenge any party's authority, right or ability to perform its obligations
under this Agreement or any of the Ancillary Agreements; (ii) challenges or

seeks to impose an Encumbrance (other than a Caldera Permitted Encumbrance) on,
or a transfer of title or ownership of, any of the Caldera Assets; (iii) asserts
that any action taken by any employee, consultant or contractor of Caldera in
connection with the Group Business infringes or misappropriates any Intellectual
Property Rights of any third party; (iv) seeks to enjoin, prevent or hinder
operation of the Caldera Business or the consummation of any of the transactions
contemplated by this Agreement or any of the Ancillary Agreements; (v) would
impair or have an adverse affect on Newco's right or ability to use or exploit
any of the Caldera Assets; or (vi) involves or relates to any potentially
material claim against Caldera by any creditor of Caldera or involves any claim
of fraudulent conveyance or any similar claim, except in cases (ii), (iii) and
(v) where such proceeding could not reasonably be expected to have a Material
Adverse Effect on Newco.

     3.8  Valid Issuance.  The Newco Common Stock that is being issued hereunder
in connection with the SCO Transaction, when issued and delivered in accordance
with the terms of this Agreement for the consideration expressed herein, will be
duly authorized and validly issued, fully paid, and nonassessable.

Balance Sheet Date there has not occurred:

          (a) any change or event which could reasonably be expected to have a
     Material Adverse Effect on Caldera; provided, however, that in no event
     will a change in the trading price of Caldera Common Stock be deemed a
     Material Adverse Effect on Caldera;

          (b) any amendments or changes in the Certificate of Incorporation or
     Bylaws (or equivalent governing documents in each relevant jurisdiction) of

     Group or, with respect to dividends or other distributions of cash or
     property arising from the Caldera Business;

3.10, and no unexpired waivers of statutes of limitations have been given or
requested with respect to Tax returns or Taxes of any member of the Caldera
Group. No taxing authority is currently conducting an audit or investigation of
any of the aforesaid Tax returns or, to Caldera's Knowledge, is about to conduct

Statements, and to Caldera's Knowledge no proposed (but unassessed) additional
Taxes have been asserted and no Tax liens have been filed against Caldera or any
of the Caldera Assets other than for Taxes not yet due and payable. Neither
Caldera, nor any member of the Caldera Group (i) has made an election to be
treated as a "consenting corporation" under Section 341(f) of the Internal
Revenue Code or (ii) is a "personal holding company" within the meaning of
Section 542 of the Internal Revenue Code.

     3.11  Intellectual Property.

          (a) Caldera owns, or has the right to use, sell or license such
     Intellectual Property Rights as are necessary or required for the Conduct
     of the Caldera Business (such Intellectual Property Rights being
     hereinafter collectively referred to as the "Caldera IP Rights") and such
     ownership or rights to use, sell or license are reasonably sufficient for
     the Conduct of the Caldera Business, except for any failure to own or have
     the right to use, sell or license that would not have a Material Adverse
     Effect on Caldera.

          (b) All Caldera IP Rights are owned free and clear of any
     Encumbrances.

          (c) To Caldera's Knowledge, (i) neither the manufacture, marketing,
     license, sale or intended use of any product currently licensed or sold by
     Caldera or any of the Caldera Subsidiaries or currently under development
     by Caldera or any of the Caldera Subsidiaries violates any license or
     agreement relating thereto or infringes any Intellectual Property Right of
     any other party, (ii) there is no pending or threatened claim or litigation
     contesting the validity, ownership or right to use, sell, license or
     dispose of any Caldera IP Right and (iii) no third party has notified
     Caldera that any Caldera IP Right or the proposed use, sale, license or
     disposition thereof, conflicts or will conflict with the rights of any
     other party, nor is there any basis therefor except for any violations,
     infringements, claims or litigation that would not have a Material Adverse
     Effect on Caldera.

     3.12  Fees and Expenses.  Except for the fees and expenses set forth in
Caldera's engagement letter with Broadview, a copy of which has been provided to
SCO, neither Caldera, Newco nor any of the

     3.13  Environmental Matters.

          (a) During the period that Caldera has leased or owned its respective
     properties or owned or operated its respective facilities, there have been,
     to Caldera's Knowledge, no disposals, releases or threatened releases of
     Hazardous Materials on, from, under or about such properties or facilities
     which would cause a Material Adverse Effect on Newco. To Caldera's
     Knowledge there is no presence, disposals, releases or threatened releases
     of Hazardous Materials on, from, under or about any of such properties or
     facilities, which may have occurred prior to Caldera having taken
     possession of any of such properties or facilities where such Hazardous
     Materials would cause a Material Adverse Effect on Newco.

          (b) None of the properties or facilities of Caldera is or has been the
     subject of an Environmental Damage, which would cause a Material Adverse
     Effect on Newco. During the time that Caldera has owned or leased its
     respective properties and facilities, none of Caldera nor, to Caldera's
     Knowledge, any third party, has used, generated, manufactured or stored on,
     under or about such properties or facilities or transported to or from such
     properties or facilities any Hazardous Materials (except those Hazardous
     Materials associated with general office use or janitorial supplies) in a
     manner which would result in a Material Adverse Effect on Newco.

          (c) During the time that any members of the Caldera Group have owned
     or leased its respective properties and facilities, to Caldera's Knowledge,
     there has been no litigation brought or threatened against any of them by,
     or any settlement reached by any of them with, any party or parties
     concerning the presence, disposal, release or threatened release of any
     Hazardous Materials on, from or under any of such properties or facilities
     or relating to any alleged Environmental Violation, except for litigation
     or settlement which would not have a Material Adverse Effect on Newco.

     3.14  Fairness Opinion.  Caldera's Board of Directors has received an

date hereof, the Caldera Ratio is fair to Caldera from a financial point of
view.

     3.15  Tax Representations.  Caldera, Newco and the Caldera Significant
Stockholders are aware of no plan or intention by Caldera or Newco or any
corporation related to Caldera immediately after the Effective Time to
repurchase any Newco capital stock issued pursuant to this Agreement from any

     or indirect subsidiaries (other than any member(s) of the Contributed
     Company Group), equity securities (other than the Contributed Stock), or
     assets (other than Group Assets), or the merger, consolidation, business
     combination, recapitalization, liquidation, dissolution or similar
     transaction involving the Retained SCO Business.

          (b) Notwithstanding Section 4.14(a), prior to obtaining the approval
     of the stockholders of SCO of this Agreement and the SCO Transaction by the
     requisite vote under applicable law (the "SCO Stockholder Approval"), SCO
     may in response to an unsolicited bona fide SCO Alternative Proposal,
     participate in discussions or negotiations with, furnish information to a
     third party making such proposal (provided that SCO shall have entered into
     a confidentiality agreement with such third party with terms no less
     favorable than in the letter with Caldera), make or authorize a statement
     or recommendation in support of such proposal, if all of the following
     events shall have occurred: (i) such third party has made a bona fide
     written offer or proposal to the Board of Directors of SCO to consummate a
     SCO Alternative Proposal which offer or proposal identifies a price or
     range of values to be paid for the outstanding securities or assets of SCO,
     the Contributing Companies or the Contributed Company Group, (ii) if
     consummated, based on the written advice of investment bankers
                                      A-34
<PAGE>   283

     of nationally recognized reputation, such Board of Directors has determined
     that it is financially more favorable to the stockholders of SCO than the
     terms of the transactions contemplated by this Agreement, (iii) such Board
     of Directors has determined, after consultation with investment bankers of
     nationally recognized reputation, that such third party is financially
     capable of consummating such SCO Alternative Proposal (if the SCO
     Alternative Proposal is for cash); (iv) such Board of Directors has
     determined, after consultation with outside legal counsel, that failure to
     take such action would be inconsistent with the fiduciary duties of the
     Board of Directors to SCO stockholders under applicable law; and (v)
     Caldera shall have been notified by SCO in writing of such SCO Alternative
     Proposal, including its principal financial and other material terms and
     conditions, including the identity of the person making such proposal (it
     being understood that any amendment to the price exchange ratio, identity
     or principal financial or other material terms shall require an additional
     notice).

          (c) In addition to the obligations set forth in Section 4.14(a), SCO,
     as promptly as practicable, shall advise Caldera orally and in writing of
     any request for non-public information which SCO reasonably believes could
     lead to a SCO Alternative Proposal, or of any SCO Alternative Proposal, the
     principal financial and other material terms and conditions of such SCO
     Alternative Proposal, and the identity of the person making any such
     request or SCO Alternative Proposal. SCO will keep Caldera informed in all
     material respects of the status and details (including material amendments)
     of any such SCO Alternative Proposal.

     4.15  Books and Records.  If, in order to properly prepare documents
required to be filed with governmental authorities (including taxing
authorities) or its financial statements, it is necessary that any party hereto
be furnished with additional information relating to the Group Assets or any
member of the Contributed Company Group, and such information is in the
possession of a Contributing Company, then SCO, for itself and the other
Contributing Companies, agree to use its good faith efforts to promptly furnish
such information to the party needing such information. This Section 4.15 shall
survive Closing for two years except for records relating to preparation or
audit of tax returns, for which this Section 4.15 will survive until the
expiration of the applicable Tax statute of limitations.

     4.16  [Intentionally Omitted.].

     4.17  Modification of Joint Contributed Agreements and Shared Contributed
Assets.  SCO will provide to Caldera a list of the Contributed Contracts and the
contracts to which the Contributed Companies are a party which create rights or
obligations of both the Group Business and the SCO Retained Business (the "Joint
Contributed Agreements"). As soon as feasible after the date hereof, SCO and
Caldera will negotiate to agree upon a mutually acceptable arrangement between
SCO and Newco and, if required, other parties with respect to the treatment of
such contracts. SCO will provide a list of the Contributed Assets which would be
impracticable to operate separately by either SCO or Caldera (the "Shared
Contributed Assets"). As soon as feasible after the date hereof, SCO and Caldera
will negotiate to agree upon a mutually acceptable arrangement, which shall
allocate costs in proportion to the benefits received, between SCO and Newco
with respect to such Shared Contributed Contracts.

     4.18  Key Employee Employment Agreements.  SCO will use its best efforts to
cause (without having to incur any cost) each of the Key Employees listed on
Exhibit 4.18A to execute employment agreements which reflect the terms set forth
in the Key Employee Term Sheet, a form of which is attached hereto as Exhibit
4.18B.

     4.19  SCO IP Rights.  As soon as feasible after the date hereof SCO and
Caldera shall confirm whether the Intellectual Property Rights and Intangible
Assets required for the production, development, marketing and support of the
Group Products are included in the Intellectual Property Rights included in the
Group Assets duly transferred to Newco pursuant hereto. If additional items not
so transferred are discovered, then the Group Assets shall be expanded to
include, and there shall be duly assigned to Newco by the appropriate
Contributing Company, all such additional Intellectual Property Rights and
Intangible Assets required for the production of the Group Products. If the
Intellectual Property Rights and Intangible Assets included or added to the
Group Assets are also required for the production of the

                                      A-35
<PAGE>   284

products produced by SCO and its subsidiaries (other than the Group Products)
then Newco (or its subsidiary, which receives said Intellectual Property Rights
and Intangible Assets constituting Group Assets) shall provide SCO, or its
designated subsidiary, with a fully paid, non-exclusive, perpetual, irrevocable
license to use such Intellectual Property Rights and Intangible Assets for the
purpose of producing such other products. SCO agrees that if Caldera determines,
in its sole judgment to register the copyrights assigned to it pursuant to the
Copyright Assignments, then SCO shall take all reasonable actions to assist
Caldera to register such copyrights.

     4.20  Directors' and Officers' Liability Insurance.  SCO shall use its
commercially reasonable efforts to maintain directors' and officers' liability
insurance as SCO shall have in effect from time to time, covering the acts or
omissions on or before the Effective Time of those Employees who are or have
been directors and officers of SCO or its subsidiaries and who become employees
of Newco as of the Effective Time. SCO will not voluntarily seek to increase the
deductible nor decrease the limits under such insurance, provided however such
action shall be governed by the insurance marketplace on commercially reasonable
and available terms, and SCO will endeavor to give written notice to Caldera
prior to any cancellation or non-renewal of the SCO coverage.

     4.21  Closing Group Account.  SCO shall deliver to Newco the assets and
liabilities section of a balance sheet of the Group Business as of the Closing
Date (the "Closing Group Account") within thirty days following the Closing
Date. Newco shall cooperate by providing access to data and personnel, as
reasonably required by SCO to prepare the Closing Group Account. The Closing
Group Account shall be prepared in the same manner as the 2000 Group Balance
Sheet and in compliance with the representations and warranties contained in
Section 2.4(c) hereof.

     4.22  SCO Retained Business.  SCO shall use its reasonable best efforts to
transfer or sell all of the Excluded Assets from the Contributed Companies prior
to the Effective Time or as soon as practicable thereafter; provided, however,
that to the extent that any Excluded Assets pursuant to Section 1.4(b)(ii) are
included as assets on the Closing Group Account, Caldera shall pay to SCO an
amount, in cash, equal to amount of such assets or transfer the assets after the
Effective Time, as the parties may agree.

     4.23  Taking of Necessary Action; Further Action.  If, at any time after
the Closing Date, any further action is necessary or desirable to carry out the
purposes of this Agreement and to vest Caldera with full right, title and
possession to the Contributed Assets and Contributed Companies, the officers and
directors of SCO are fully authorized in the name SCO or otherwise to take, and
will take, all such lawful and necessary and/or desirable action.

     4.24  Accounting Treatments.  SCO and Caldera shall use their reasonable
best efforts to gain favorable accounting treatment for the Sales Representative
and Support Agreement, including, if necessary, revising the terms of such
agreement set forth in Exhibit 4.12.

     5.  Caldera and Newco Covenants.

     5.1  Advice of Changes.

          (a) During the period from the date hereof until the earlier of the
     Effective Time or the termination of this Agreement in accordance with its
     terms, Caldera will promptly advise SCO in writing (i) of any event
     occurring subsequent to the date hereof that would reasonably be likely to
     render any representation or warranty of Caldera or Newco contained in
     Section 3 of this Agreement, if made on or as of the date of such event or
     the Effective Time, untrue or inaccurate, (ii) of any event that would
     reasonably be likely to have a Material Adverse Effect on Caldera, and
     (iii) of any material breach by Caldera or Newco of any covenant or
     agreement contained in this Agreement; provided, however, that the delivery
     of, or failure to deliver, any notice pursuant to this Section 5.1(a) shall
     not limit or otherwise affect the remedies available hereunder.

          (b) Ten days prior to the Effective Time, Caldera will deliver to SCO
     a certificate from Caldera's transfer agent indicating the number of shares
     of Common Stock outstanding at the end of business on the eleventh day
     preceding the Effective Time and a certificate from Caldera's Secretary

                                      A-36
<PAGE>   285

     indicating the number of shares of Caldera Common Stock issuable upon
     exercise or conversion of any outstanding options, warrants or convertible
     debentures outstanding on such date. Caldera will deliver to SCO by the
     fifteenth business day after the Effective Time a certificate from
     Caldera's transfer agent indicating the number of shares of Common Stock
     outstanding at the end of business on the day of the Closing (calculated
     without regard to the shares of Common Stock issued with respect to the
     First SCO Certificate) and a certificate from Caldera's Secretary
     indicating the number of shares of Caldera Common Stock issuable upon
     exercise or conversion of any outstanding options at the end of business on
     the day of the Closing.

     5.2  Maintenance of Business.  During the period from the date hereof until
the earlier of the Effective Time or the termination of this Agreement in
accordance with its terms, Caldera will use its best efforts to carry on and
preserve its business and its relationships with customers, suppliers, employees
and others in substantially the same manner as it has prior to the date hereof.

     5.3  Conduct of Business.  During the period from the date hereof until the
earlier of the Effective Time or the termination of this Agreement in accordance
with its terms, Caldera will continue to conduct its business and maintain its
business relationships in the ordinary and usual course and consistent with past
practice and, except as otherwise disclosed herein or in the Caldera Disclosure
Letter, it will not, without the prior written consent of SCO, which consent
shall not be unreasonably withheld or delayed, take any of the following actions
where it would cause a Material Adverse Effect on Caldera:

          (a) borrow any money except for (A) amounts that are not in the
     aggregate material to the financial condition of Caldera and its
     subsidiaries, taken as a whole or (B) pursuant to existing credit
     facilities;

          (b) cause any of the material Caldera Assets to become subject to any
     Encumbrance, except for Caldera Permitted Encumbrances and except for
     Caldera Encumbrances arising under credit facilities existing as of the
     date hereof;

          (c) dispose of any of Caldera Assets which are material to the Caldera
     Business;

          (d) issue capital stock representing more than a 10% interest in the
     total outstanding securities of Caldera;

          (e) merge, consolidate or reorganize with, or acquire any entity,
     except for transactions in which the aggregate consideration is below $15
     million;

          (f) amend the Certificate of Incorporation or Bylaws of Caldera or any
     of its subsidiaries or as otherwise expressly contemplated by this
     Agreement);

          (g) agree to take, or permit any Caldera entity to take or agree to
     take, or enter into negotiations with respect to, any of the actions
     described in the preceding clauses in this Section 5.3(g).

     Notwithstanding the foregoing, nothing in this Section 5.3 shall restrict
or limit the conduct of any business of Caldera or its direct or indirect
subsidiaries or the use or disposition of the Caldera Assets, other than as set
forth in this Section 5.3.

     5.4  Stockholder Approval.  Caldera will call the Caldera Stockholders
Meeting, to be held within 40 days after the Form S-4 shall have been declared
effective by the SEC, to submit the Merger, the SCO Transaction and any related
matters for the consideration and approval of the Caldera stockholders. The
Prospectus/Proxy Statement will include a statement to the effect that Caldera's
Board of Directors is recommending that Caldera stockholders vote in favor of
the Merger and the SCO Transaction. Such meeting will be called, held and
conducted, and any proxies will be solicited, in compliance with applicable law.

     5.5  Letter of Caldera's Accountants.  Caldera shall use its reasonable
best efforts to cause to be delivered to SCO a letter of Arthur Andersen LLP,
dated a date within two business days before the date
                                      A-37
<PAGE>   286

on which the Form S-4 shall become effective and addressed to each of the
Contributing Companies, in form and substance reasonably satisfactory to SCO and
customary in scope and substance for letters delivered by independent public
accountants in connection with registration statements similar to the Form S-4.

     5.6  Prospectus/Proxy Statement.  Caldera will mail to its stockholders in
a timely manner, for the purpose of considering and voting upon the Merger and
the SCO Transaction at the Caldera Stockholders Meeting, the Prospectus/Proxy
Statement. SCO, Caldera and Newco will prepare and file the Prospectus/ Proxy
Statement with the SEC as promptly as practicable, and each will use its
respective best reasonable efforts to cause the Form S-4 to become effective as
soon after such filing as practicable. In this regard, SCO, Caldera and Newco
will advise each other promptly as to the time at which the Form S-4 becomes
effective and of the issuance by the SEC of any stop order suspending the
effectiveness of the Form S-4 or the initiation of any proceedings for such
purpose and each will use its respective reasonable best efforts to prevent the
issuance of any stop order and to obtain as soon as possible the lifting
thereof, if issued. Until the Effective Time, Caldera and Newco will advise SCO
promptly of any requirement of the SEC for any amendment or supplement of the
Form S-4 or for additional information, and will not at any time file any
amendment of or supplement to the prospectus contained therein (or to the
prospectus filled pursuant to Rule 424(b) of the SEC) which shall not have been
previously submitted to SCO in reasonable time prior to the proposed filing
thereof or to which SCO shall reasonably object or which is not in compliance in
all material respects with the Securities Act and the rules and regulations
issued by the SEC thereunder. None of the information relating to Caldera or
Newco (or, to Caldera's or Newco's knowledge, any other person, contained in any
document, certificate or other writing furnished or to be furnished by Caldera)
included in (i) the Prospectus/Proxy Statement by Newco and/or Caldera at the
time the Prospectus/ Proxy Statement is mailed, at the time of the Caldera
Stockholders Meeting to vote on the Merger and the SCO Transaction or at the
Effective Time, as then amended or supplemented, or (ii) the Form S-4 at the
time the Form S-4 becomes effective, as then amended or supplemented, will
contain any untrue statement of a material fact or will omit to state any
material fact required to be stated therein or necessary to make the statements
therein, in light of the circumstances in which they were made, not misleading
or necessary to correct any statement which has become false or misleading in
any earlier communication with respect to the solicitation of proxies for the
Caldera Stockholder Meeting. From and after the date the Form S-4 becomes
effective and until the Effective Time, if any event known to Caldera or Newco
occurs as a result of which the Prospectus/Proxy Statement or Form S-4 would
include an untrue statement of a material fact or omit to state a material fact
required to be stated therein or necessary to make the statements therein not
misleading, or if it is necessary at any time to amend the Form S-4 or the
Prospectus/Proxy Statement to comply with the Securities Act, Caldera and Newco
will promptly notify SCO and SCO, Caldera and Newco will prepare an amended or
supplemented Form S-4 or Prospectus/Proxy Statement which will correct such
statement or omission and will use its reasonable best efforts to cause any such
amendment to become effective as promptly as possible. The Prospectus/ Proxy
Statement, as it relates to Caldera and Newco, will comply as to form in all
material respects with the requirements of the Exchange Act and the rules and
regulations thereunder in effect at the time the Prospectus/Proxy Statement is
mailed.

     5.7  State Securities Law Compliance.  Caldera and Newco shall use their
respective reasonable best efforts to qualify the Newco Options to be granted
upon cancellation of the Cancelled SCO Options to be assumed by Caldera pursuant
hereto under the state securities or "blue sky" laws of every jurisdiction of
the United States in which (a) the records of Caldera or SCO as of the Effective
Time, indicate that a holder of such options resides and (b) a Nasdaq Stock
Market or other exemption from the qualification requirements under such laws is
unavailable.

     5.8  Regulatory Approvals.  As promptly as reasonably practicable, Caldera
and Newco will execute and file, or join in the execution and filing, of any
application or other document that may be necessary in order to obtain the
authorization, approval or consent of any governmental body, federal, state,
provincial, local or foreign which may be reasonably required, or which SCO may
reasonably request, in connection with the consummation of the transactions
contemplated by this Agreement. Caldera and Newco will each

                                      A-38
<PAGE>   287

use its respective reasonable efforts to promptly obtain all such
authorizations, approvals and consents and will cooperate fully with the other
parties in promptly seeking to obtain all such authorizations, approvals, and
consents.

     5.9  Necessary Consents.  Caldera and Newco will each use its respective
reasonable efforts to obtain the written consents under the Material Caldera
Contracts and to take such other actions as may be necessary or appropriate to
allow the consummation of the transactions contemplated hereby and to allow
Caldera and Newco to carry on Caldera's business and the Group Business after
the Effective Time.

     5.10  Access to Information.  From the date hereof until the Effective
Time, Caldera and Newco will allow the Contributing Companies and its agents
reasonable access to the files, books, records, technology and offices of
Caldera or Newco reasonably requested by the Contributing Companies including,
without limitation, any and all information relating to Taxes, commitments,
contracts, leases, licenses and real, personal, intellectual and intangible
property and financial condition. Caldera will use its reasonable efforts to
cause its accountants to cooperate with the Contributing Companies and its
agents in making available to such parties all financial information reasonably
requested, including, without limitation, the right to examine all working
papers pertaining to all Tax returns and financial statements prepared or
audited by such accountants. No information or knowledge obtained by any party
hereto in any investigation pursuant to this Section will affect or be deemed to
modify any representation or warranty contained herein or the conditions to the
obligations of the parties to consummate the Merger and the SCO Transaction. All
information obtained by the Contributing Companies or its agents pursuant to
this Section shall be kept confidential in accordance with the Nondisclosure
Agreement.

     5.11  Books and Records.  If, in order properly to prepare documents
required to be filed with governmental authorities (including taxing
authorities) or its financial statements, it is necessary that any party hereto
be furnished with additional information relating to the Group Assets, and such
information is in the possession of Newco or Caldera, then Caldera and Newco on
behalf of themselves and each member of the Caldera Group (including the
Contributed Companies) agree to use its good faith efforts to promptly furnish
such information to the party needing such information. This Section 5.11 shall
survive Closing for two years except for records relating to preparation of and
audit of tax returns, for which this Section 5.11 will survive until the
expiration of the applicable Tax statute of limitations.

     5.12  Satisfaction of Conditions Precedent.  Caldera and Newco will each
use their respective reasonable best efforts to satisfy or cause to be satisfied
all the conditions precedent that are set forth in Section 7 and to cause the
Merger, the SCO Transaction and the other transactions contemplated by this
Agreement to be consummated. Without limiting the foregoing, in connection with
the agreements to be reached by the parties subsequent to the date hereof and
prior to the Effective Time, the parties agree to negotiate in good faith to
reach agreement on all matters to be included in such agreements promptly after
the signing of this Agreement.

     5.13  Voting Agreement.  Caldera will use its reasonable best efforts to
obtain Voting Agreements in the form attached as Exhibit 4.11A executed by the
Caldera affiliates listed on Exhibit 5.13B.

     5.14  Sales Representative and Support Agreement.  The Sales Representative
and Support Agreement shall be executed as of the Effective Time.

     5.15  Stockholders Agreement.  The Stockholders Agreement shall be executed
as of the Effective Time.

     5.16  Caldera Employee Plans.

          (a) Newco will adopt the employee benefit plans maintained by Caldera
     (the "Caldera Employee Plans") and will use reasonable efforts to provide
     the Caldera Employee Plans to the transferring Employees as is provided to
     Caldera's employees who are similarly situated as soon as practicable. To
     the extent that Newco does not have Caldera Employee Plans in effect in a
     jurisdiction where there are transferring Employees, Newco shall adopt
     plans providing comparable benefits to the Caldera Employee Plans for said
     transferring Employees. From and after the Effective

                                      A-39
<PAGE>   288

     Time Newco shall provide all transferring Employees with the opportunity to
     participate in any employee stock option or other incentive compensation
     plan of Newco and its affiliates on substantially the same terms and
     subject to substantially the same conditions as are available to similarly
     situated employees of Caldera or Newco. Prior to the Effective Time,
     Caldera, Newco and SCO shall mutually agree upon an integration plan
     relating to the Merger and the SCO Transaction which shall include, among
     other things, provisions relating to compensation and other equity
     incentives for Employees. In addition, at the Effective Time, Newco shall
     use its best efforts to enter into employment agreements which reflect the
     terms set forth in the Key Employee Term Sheets (the form of which is
     attached hereto as Exhibit 4.18B) with the Key Employees who are identified
     on Exhibit 4.18A attached hereto.

          (b) Waiting Periods, Premiums and Deductibles.  Newco shall take all
     steps necessary to cause each Caldera Employee Plan to waive any "waiting
     period" or other requirement with respect to duration of employment with
     Newco which would prevent a transferring Employee or beneficiary thereof
     who is otherwise eligible to participate in such Caldera Employee Plan from
     participating in such Caldera Employee Plan immediately following the
     Effective Time. Newco shall credit each transferring Employee with all
     deductible payments and co-payments paid by such transferring Employee
     under any Group Employee Plan prior to the Effective Time during the
     current plan year for purposes of determining the extent to which any such
     transferring Employee has satisfied any deductible or maximum out-of-pocket
     limitation under any Caldera Employee Plan for such plan year.

          (c) Recognition of Prior Service.  Newco shall take all steps
     necessary to cause each Caldera Employee Plan to recognize each
     transferring Employee's length of service under comparable employee benefit
     plans maintained by SCO for purposes of eligibility, participation, vesting
     and benefit accrual in such Caldera Employee Plan as if such transferring
     Employee had been employed by Newco for such period.

          (d) Waiver of Restrictions.  Newco shall take all steps necessary to
     cause each Caldera Employee Plan which is an "employee welfare benefit
     plan" under Section 3(1) of ERISA to waive any restrictions or limitations
     with respect to "pre-existing conditions" or prior medical history which
     would apply to transferring Employee or beneficiary thereof who is
     otherwise eligible to participate in such Caldera Employee Plan from
     participating in such Caldera Employee Plan without restriction or
     limitation.

     5.17  Indemnification and Insurance -- Caldera.

          (a) The Certificate of Incorporation and Bylaws of Newco and Caldera
     shall contain the provisions with respect to indemnification and limitation
     of liability for monetary damages set forth in the Certificate of
     Incorporation and Bylaws of Caldera on the date hereof.

          (b) From and after the Effective Time, Newco and Caldera shall honor,
     in all respects, all of the indemnity agreements entered into prior to the
     date hereof by Caldera, with its respective officers and directors, whether
     or not such persons continue in their positions with Newco or Caldera
     following the Effective Time. Following the Effective Time, Caldera's form
     of indemnification agreement shall be adopted as the form of
     indemnification agreement for Newco and the Caldera Surviving Corporation
     shall be afforded the opportunity to enter into such indemnification
     agreement, and shall be covered by such directors' and officers' liability
     insurance policies as Newco shall have in effect from time to time.

          (c) After the Effective Time, Newco and Caldera will, jointly and
     severally, to the fullest extent permitted under applicable law, indemnify
     and hold harmless, each present and former director or officer of Caldera
     or any of its subsidiaries (collectively, the "Indemnified Parties")
     against any costs or expenses (including attorneys' fees), judgments,
     fines, losses, claims, damages, liabilities and amounts paid in settlement
     in connection with any claim, action, suit, proceeding or investigation,
     whether civil, criminal administrative or investigative, to the extent
     arising out of or pertaining to any
                                      A-40
<PAGE>   289

     action or omission in his or her capacity as a director or officer of
     Caldera arising out of or pertaining to the transactions contemplated by
     this Agreement or the transactions contemplated hereby for a period of six
     years after the date of this Agreement. In the event of any such claim,
     action, suit, proceeding or investigation (whether arising before or after
     the Effective Time), (a) any counsel retained for the defense of the
     Indemnified Parties for any period after the Effective Time will be
     reasonably satisfactory to the Indemnified Parties, (b) after the Effective
     Time, Caldera will pay the reasonable fees and expenses of such counsel,
     promptly after statements therefor are received, and (c) Caldera will
     cooperate in the defense of any such matter; provided, however, that
     Caldera will not be liable for any settlement effected without its written
     consent (which consent will not be unreasonably withheld); and provided,
     further, that, in the event that any claim or claims for indemnification
     are asserted or made within such six-year period, all rights to
     indemnification in respect of any such claim or claims will continue until
     the disposition of any and all such claims. The Indemnified Parties as a
     group may be defended by only one law firm (in addition to local counsel)
     with respect to any single action, unless there is, under applicable
     standards of professional conduct, a conflict on any significant issue
     between the positions of any two or more Indemnified Parties.

          (d) For the entire period from and after the Effective Time until at
     least six years after the Effective Time, Newco will cause Caldera to use
     its commercially reasonable efforts to maintain in effect directors' and
     officers' liability insurance covering those persons who are currently
     covered by Caldera's directors' and officers' liability insurance policy (a
     copy of which has been heretofore delivered or made available to SCO) of at
     least the same coverage and amounts, containing terms that are no less
     advantageous with respect to claims arising at or before the Effective Time
     than Caldera's policies in effect immediately prior to the Effective Time
     to those applicable to the then current directors and officers of Newco and
     Caldera; provided, however, that in no event shall Newco or Caldera be
     required to expend in excess of 150% of the annual premium currently paid
     by Caldera for such coverage in which event Newco shall purchase such
     coverage as is available for such 150% of such annual premium.

          (e) Newco and Caldera shall pay all expenses, including attorneys'
     fees, that may be incurred by any Indemnified Parties in enforcing the
     indemnity and other obligations provided for in this Section 5.17.

          (f) In the event Newco or Caldera or any of its respective successors
     or assigns (a) consolidates with or merges into any other person or entity
     and shall not be the continuing or surviving corporation or entity of such
     consolidation or merger, or (b) transfers or conveys all or a substantial
     portion of its properties or assets to any person or entity, then, and in
     each such case, to the extent necessary to effectuate the purposes of this
     Section 5.17, proper provision shall be made so that the successors and the
     assigns of Newco and Caldera assume the obligations set forth in this
     Section 5.17.

          (g) The provisions of this Section 5.17 shall survive the Effective
     Time and are intended to be for the benefit of, and shall be enforceable
     by, each officer and director of Caldera SCO and the Contributed Company
     Group described in Sections 5.17 and his or her heirs and representatives.

     5.18  Indemnification and Insurance -- Employees.

          (a) The Certificate of Incorporation and Bylaws of Newco shall contain
     the provisions with respect to indemnification and limitation of liability
     for monetary damages set forth in the Certificate of Incorporation and
     Bylaws of Caldera as of the date hereof which provisions shall not be
     amended, repealed or otherwise modified for a period of ten years from the
     Effective Time in any manner that would adversely affect the rights
     thereunder of individuals who at the Effective Time were directors,
     officers, employees or agents of (i) the Contributed Companies or (ii) of
     SCO (A) to the extent involved in the Group Business and (B) provided they
     become Employees, officers or directors of Newco ("Group Persons"), unless
     such modification is required by law.

          (b) From and after the Effective Time, Newco shall honor, in all
     respects, all of the indemnity agreements entered into prior to the date
     hereof by SCO or any member of the Contributed Company
                                      A-41
<PAGE>   290

     Group with any Group Persons, whether or not such persons continue in its
     positions with Newco following the Effective Time. Following the Effective
     Time, Caldera's form of indemnification agreement shall be adopted as the
     form of indemnification agreement for Newco and all continuing officers and
     directors of Newco shall be afforded the opportunity to enter into such
     indemnification agreement, and shall be covered by such directors' and
     officers' liability insurance policies as Newco shall have in effect from
     time to time.

          (c) After the Effective Time, Newco will, jointly and severally, to
     the fullest extent permitted under applicable law, indemnify and hold
     harmless, subject to Section 5.18(g), each of the Group Persons against any
     costs or expenses (including attorneys' fees), judgments, fines, losses,
     claims, damages, liabilities and amounts paid in settlement in connection
     with any claim, action, suit, proceeding or investigation, whether civil,
     criminal administrative or investigative, to the extent arising out of or
     pertaining to any action or omission in his or her capacity as a director
     or officer of SCO or any of the Contributed Companies arising out of or
     pertaining to the transactions contemplated by this Agreement for a period
     of six years after the Closing Date. Notwithstanding the foregoing, the
     parties agree that claims against the Group Persons shall first be made
     against any directors' and officers' liability insurance, if any, then
     maintained by SCO or any of the Contributed Companies that provides
     coverage for such Group Persons. In the event of any such claim, action,
     suit, proceeding or investigation (whether arising before or after the
     Effective Time), (a) any counsel retained for the defense of the Group
     Persons for any period after the Effective Time will be reasonably
     satisfactory to the Group Persons, (b) after the Effective Time, Newco
     will, subject to Section 5.18(g), pay the reasonable fees and expenses of
     such counsel, promptly after statements therefor are received, and (c)
     Newco will cooperate in the defense of any such matter; provided, however,
     that Newco will not be liable for any settlement effected without its
     written consent (which consent will not be unreasonably withheld); and
     provided, further, that, in the event that any claim or claims for
     indemnification are asserted or made within such six-year period, all
     rights to indemnification in respect of any such claim or claims will
     continue until the disposition of any and all such claims. The Group
     Persons as a group may be defended by only one law firm (in addition to
     local counsel) with respect to any single action unless there is, under
     applicable standards of professional conduct, a conflict on any significant
     issue between the positions of any two or more Group Persons.

          (d) Newco shall pay all expenses, including attorneys' fees, that may
     be incurred by any Group Persons in enforcing the indemnity and other
     obligations provided for its benefit in this Section 5.18.

          (e) In the event Newco or any of its respective successors or assigns
     (i) consolidates with or merges into any other person or entity and shall
     not be the continuing or surviving corporation or entity of such
     consolidation or merger, or (ii) transfers or conveys all or a substantial
     portion of its properties or assets to any person or entity, then, and in
     each such case, to the extent necessary to effectuate the purposes of this

     8.4  Termination Fee.

          (a) Termination Fee.

             (i) If this Agreement is terminated by Caldera pursuant to Section
        8.1(i), then SCO shall promptly pay to Caldera (by wire transfer or
        cashier's check) a nonrefundable fee equal to 3 1/2% of the number of
        shares of Newco Common Stock equal to the SCO Percentage Interest
        multiplied by the average closing price of the Caldera Common Stock for
        the ten (10) days following the public announcement of this Agreement
        (the "Termination Fee") within two (2) business days following delivery
        of the notice of termination by Caldera pursuant to Section 8.2;

             (ii) If this Agreement is terminated by SCO pursuant to Section
        8.1(l), then Caldera shall promptly pay to SCO (by wire transfer or
        cashier's check) the Termination Fee within two (2) business days
        following delivery of the notice of termination by SCO pursuant to
        Section 8.2; and

             (iii) If (A) this Agreement is terminated by SCO or Caldera
        pursuant to Section 8.1(h) after a SCO Alternative Proposal has been
        publicly disclosed or by Caldera pursuant to Section 8.1(c) as the
        result of a breach by SCO of Section 4.14 and (B) within 6 months of
        termination of this Agreement SCO shall enter into an agreement for a
        SCO Alternative Proposal which is subsequently consummated or within 12
        months of termination of this Agreement SCO shall consummate a SCO
        Alternative Proposal, then SCO shall pay to Caldera (by wire transfer or
        cashier's check) the Termination Fee within two (2) business days upon
        the consummation of such SCO Alternative Proposal.

          (b) SCO and Caldera acknowledge that the agreements contained in this
     Section 8.4 are an integral part of the transactions contemplated by this
     Agreement, and that, without these agreements, neither SCO nor Caldera
     would enter into this Agreement; accordingly, if either Caldera or SCO fail
     to timely pay the amounts due pursuant to this Section 8.4, and, in order
     to obtain such payment, the other party commences a suit which results in a
     judgment against SCO or Caldera, as the case may be for the amounts set
     forth in this Section 8.4 and such judgment is not set aside or reversed,
     such party shall pay the other party's reasonable costs and expenses
     (including attorneys' fees and expenses) in connection with such suit,
     together with interest on the amounts set forth in this Section 8.4 at the
     prime rate as published in The Wall Street Journal on the date such payment
     was required to be made.

     9.1  Survival of Representations.  Except as otherwise expressly provided
herein, all representations, warranties and covenants of the parties contained
in this Agreement will remain operative and in full force and effect, regardless
of any investigation made by or on behalf of the parties to this Agreement,
until the second anniversary of the Effective Time, whereupon such
representations, warranties and covenants will expire (except for covenants and
other provisions hereof that by its express terms survive for a longer period);
provided however that all representations and warranties and covenants relating
to Tax matters shall survive for the period of the applicable statute of
limitations.

deliver to the Escrow Agent Shares of Newco Common Stock equal to an aggregate

<PAGE>   296

     10.2  Indemnification by SCO.  SCO agrees, notwithstanding any provision of
Section 1.4 hereof to the contrary, to indemnify Newco and Caldera against, and

allegedly being a Liability of one of the Contributed Companies or of the
Contributed Subsidiaries):

          (a) any of the Excluded Liabilities, except as may be provided in
     Section 12;

          (b) any demand, claim, debt, suit, cause of action, arbitration,
     investigation or other proceeding made or asserted by any Contributing
     Company or any stockholder, creditor, or Affiliate of any Contributing
     Company or by any receiver or trustee in bankruptcy of any Contributing
     Company of the property or assets of any Contributing Company, asserting
     that the transfer of the Contributed Stock and Contributed Assets to Newco
     hereunder constitutes a fraudulent conveyance, fraudulent transfer or a
     preference under any applicable foreign, state or federal law, including
     but not limited to the United States Bankruptcy Code, or any breach by any
     Contributing Company of its representations and covenants in Section 1.4(e)
     hereof or any Liabilities related to non-compliance with bulk transfer laws
     in connection with the SCO Transaction;

          (c) the SCO Retained Business;

          (d) any material Liability omitted from the Group Financial Statements
     that was required by GAAP to be included or reflected therein
     (collectively, the "Omitted Balance Sheet Liabilities");

          (e) any claim or cause of action brought by any SCO employee relating
     in any way to the terms and conditions of the employee's employment with
     SCO or the termination thereof, which arises prior to the Closing Date,
     regardless of when such claim or cause of action may be discovered or
     brought;

          (f) any breach of the representations and warranties in Section 2
     hereof.

     10.3  Notwithstanding Section 10.2, all liabilities for Taxes shall be
subject only to the separate tax indemnification provisions of Section 12.

     10.4  Limitations on Indemnification.  SCO shall not have any liability
under this Section 10 unless the aggregate amount of Loss attributable exceeds
$1,000,000, and, in such event, SCO shall be required to pay the entire amount
of such Loss from the first dollar thereof. SCO shall not have liability for any
Loss in excess of the amount determined by multiplying (i) the number of shares
of Newco Common Stock equal to ten percent (10%) of the SCO Percentage Interest
by (ii) the Caldera Closing Price, except that as such Losses relate to the SCO
IP Rights, SCO shall not have liability for any Loss in excess of the amount
determined by multiplying (i) the number of Shares of Newco Common Stock equal
to fifty percent (50%) of the SCO Percentage Interest by (ii) the Caldera
Closing Price. Notwithstanding the preceding sentence, there shall be no
limitations on liability pursuant to this Section 10 relating to intentional
fraud or misrepresentation by SCO.

     10.5  Indemnification Procedures.

          (a) Claim Procedure.  If Caldera or Newco has or claims to have
     incurred or suffered Losses for which it is or may be entitled to
     indemnification, compensation or reimbursement under this Section 10 (the
     "Indemnitee"), such Indemnitee may, on or prior to the first anniversary of
     the Effective Time, deliver a claim notice (a "Claim Notice") to SCO. Each
     Claim Notice shall (i) state that such Indemnitee believes that it is
     entitled to indemnification, compensation or reimbursement under this
     Section 10, (ii) contain a brief description of the circumstances
     supporting such Indemnitee's belief that such Indemnitee is so entitled to
     indemnification, compensation or reimbursement and (iii) contain a
     non-binding, preliminary estimate of the amount of Loss such Indemnitee
     claims to have so incurred or suffered (the "Claimed Amount").

          (b) Response Notice.  Within twenty (20) business days after receipt
     by SCO of a Claim Notice, SCO may deliver to the Indemnitee who delivered
     the Claim Notice a written response (the "Response Notice") in which SCO:
     (i) agrees that the full Claimed Amount is to be paid to the Indemnitee;
     (ii) agrees that a part, but not all, of the Claimed Amount is to be paid
     to the
                                      A-48
<PAGE>   297

     Indemnitee; or (iii) indicates that no part of the Claimed Amount is to be
     paid to the Indemnitee. Any part of the Claimed Amount that SCO does not
     agree should be paid to the Indemnitee shall be the "Contested Amount." If
     a Response Notice is not delivered to Caldera within such twenty (20)
     business day period, then SCO shall be deemed to have agreed that the full
     Claimed Amount is to be paid to the Indemnitee.

          (c) Payment of Claimed Amount.  If SCO delivers a Response Notice
     agreeing that some or all of the Claimed Amount is to be paid to the
     Indemnitee (the "Agreed Amount"), SCO shall pay the Indemnitee in cash,
     within twenty (20) business days from the date of the Response Notice, any
     portion of the Agreed Amount that is not satisfied by delivery of Escrow
     Shares pursuant to the terms of the Escrow Agreement. Such payment shall be
     deemed to be made in full satisfaction of the claim described in such Claim
     Notice, provided, however, that if such claim involves ongoing Losses, then
     such payment shall be deemed to be made in full satisfaction only of the
     Losses incurred as of the date specified in such Claim Notice.

          (d) Settlement.  If SCO delivers a Response Notice indicating that
     there is a Contested Amount, SCO and the Indemnitee shall attempt in good
     faith for a period of thirty (30) days from the date of the Response Notice
     to resolve the dispute related to the Contested Amount. If the Indemnitee
     and SCO resolve such dispute, such resolution shall be binding on SCO and
     all of the Indemnitees and a settlement agreement shall be signed by the
     Indemnitee and SCO containing the terms of such resolution.

          (e) Third Party Claims.

             (i) Within fifteen (15) days after receipt of notice of
        commencement of any action by any third party evidenced by service of
        process or other legal pleading, or with reasonable promptness after the
        assertion in writing of any claim by a third party, Caldera shall give
        SCO written notice thereof together with a copy of such claim, process
        or other legal pleading, and SCO shall have the right to undertake the
        defense, thereof through a legal representative of SCO's own choosing.

             (ii) In the event that SCO, by the thirtieth day after receipt of
        notice of any such claim (or, if earlier, by the tenth day preceding the
        day on which an answer or other pleading must be served in order to
        prevent judgment by default in favor of the person asserting such
        claim), does not elect to defend against such claim, Caldera (upon
        further notice to SCO) will have the right to undertake the defense,
        compromise or settlement of such claim on behalf of and for the account
        and risk of SCO subject to the right of SCO to assume the defense of
        such claims at any time prior to settlement, compromise or final
        determination thereof. The reasonable costs of defense of any third
        party action or claim by Caldera shall be paid from the Escrow Shares.

             (iii) Notwithstanding Sections 11.5(e)(i) and (ii), Caldera shall
        have the right to retain control of the defense of any third party
        action or claim described in Section 11.5(e)(i) which involves potential
        Losses in excess of the value of the Escrow Shares remaining in the
        Escrow Account or could reasonably be expected to materially affect
        Caldera's on-going operations. In such event, SCO shall have the right
        to be present at the negotiation, defense and settlement of such action
        or claim. Caldera shall not agree to any settlement of any such action
        or claim without the consent of SCO, which shall not be unreasonably
        withheld.

          (f) Satisfaction.  In the event SCO incurs liability for Losses which
     is not satisfied by delivery of shares from the Escrow Fund, SCO may elect
     to pay the amount due either in cash or by delivering shares of Newco
     Common Stock. For this purpose, the Newco Common Stock will be valued at
     the average closing price of the Caldera Common Stock for the ten days
     following the public announcement of this Agreement, as adjusted for stock
     splits, stock dividends, changes in the Caldera Ratio and other
     recapitalizations.

     11. Employee Matters.

     11.1  Right to Offer Employment.

          (a) Employees.  Schedule 11.1 of the SCO Disclosure Letter contains a
     preliminary list (the "Preliminary List") of each Contributed Company
     employee or consultant and each other employee or consultant of SCO or the
     Group Business who works in, or provides services in connection with or is
     assigned to the Group Business or any of the Group Assets (each a
     "Potential Employee"). Within five (5) days after the date hereof, SCO
     shall deliver to Newco a final list of the Potential Employees (the "Final
     List"), which list shall identify those Potential Employees who are active
     employees of the Group Business as of that date, including those on
     vacation, sick leave, maternity or parental leave, disability leave, family
     leave or personal leave of absence, who work full or part time, and which
     shall separately identify those employees who are on a workers'
     compensation-related or disability leave or long-term sick leave. The Final
     List shall contain, with respect to each Potential Employee, a true and
     accurate list of all locations at which Potential Employees are working as
     of such date, together with the date of hire, location of employment, years
     of employment or service, current annual base salary or base wage, and of
     all other compensation arrangements for such Potential Employees, including
     bonuses, commissions or other compensation arrangements or benefit plans
     whether oral or written, contractual or discretionary. Within sixteen (16)
     days of receipt of the Final List, Caldera shall deliver to SCO a list that
     identifies: (i) those Potential Employees of the Group Business to whom it
     shall make offers of employment and (ii) those Potential Employees of the
     Contributed Companies that it expects to retain, each pursuant to Section
     11.1(e) (the "Designated Employees"). For purposes of this Agreement,
     "Employees" means only those Designated Employees given offers of
     employment or retained by Newco pursuant to Section 11.1(e). For a period
     of two years from the Closing Date, neither Newco, any of its subsidiaries
     nor their employees (including former employees of SCO) may employ, make
     offers of employment to or otherwise solicit any employees of SCO as of the
     date hereof who are not Designated Employees.

          (b) The parties acknowledge and agree that in those jurisdictions in
     which the EC Directive 77/187 (the Acquired Rights Directive) (the
     "Employment Regulations") apply, the contracts of employment of the
     Designated Employees designated as "Employees" pursuant to Section 11.1(e)
     will have effect from the Effective Time (which shall be the "time of
     transfer" for the purposes of the Employment Regulations) as if originally
     made between Newco and each such Employee. If any contract of employment is
     not disclosed by SCO in the Final List or any other contract of employment
     of any employee other than an Employee is in effect as if originally made
     between Newco and the employee concerned as a result of the Employment
     Regulations: (i) Newco may, upon becoming aware of any such contract,
     terminate it forthwith; and (ii) SCO and each Group Business shall
     indemnify and hold harmless Newco against any costs, claims, liabilities
     and expenses of any nature (including legal expenses on an indemnity basis)
     arising out of such termination and against sums payable to or on behalf of
     such employee in respect of his employment whether arising before or after
     the Closing.

          (c) Newco shall credit Employees with their then current accrued
     vacation with SCO or the Contributed Companies. All other emoluments and
     outgoings (including and without limitation, wages, salaries, bonuses,
     commissions, withholding taxes, social security contributions, pension
     contributions) and other costs and expenses of, and all other obligations
     in respect of, the Employees in respect of the period to, and including,
     the Closing shall be discharged by SCO and any relevant Group Business. SCO
     and each Group Business shall indemnify and keep indemnified Newco against
     all liabilities arising from any failure by SCO and any Group Business so
     to discharge.

          (d) SCO and each Group Business shall indemnify and hold harmless
     Newco from and against all losses, costs, claims, demands, actions, fines,
     penalties, awards, liabilities and expenses (including legal expenses on an
     indemnity basis) (i) which are attributable to any act, omission, breach or
     default by SCO or any Group Business prior to the Closing in respect of any
     of the obligations of SCO or any Group Business (in either case, whether
     arising under common law, statute, custom or

                                      A-50
<PAGE>   299

     otherwise) to or in relation to any of its employees or former employees
     (including but not limited to any liability arising out of the termination
     or dismissal of any Potential Employee or former employee and which Newco
     may incur or suffer as a result of succeeding to SCO or any Group Business
     as the employer of any Potential Employee); or (ii) in connection or as a
     result of any claim or demand by a Potential Employee on the grounds that
     the Potential Employee has suffered any loss, harm or damage in relation to
     pension rights caused by the transactions set forth in this Agreement
     (including without limitation the calculation of any transfer value of
     accrued rights on transfer) to the Potential Employees; or (iii) in
     connection or as a result of any claim or demand by a Potential Employee
     that the identity of Newco is to the Potential Employee's detriment,
     whether or not such claim or claims arises or arise prior to, on or after
     the Closing.

          (e) Offers of Employment.  Effective at the Effective Time, Newco
     shall offer to employ any of the Designated Employees of the Group Business
     (other than Designated Employees of the Contributed Companies) subject to
     Newco's standard terms, conditions and policies of employment and the terms
     of this Agreement, and shall offer such Designated Employees as it
     determines, in its sole discretion, to hire (i) salary consistent with the
     salary earned by such Potential Employees prior to the Effective Time but
     only to the extent such salary is not in excess of industry norms (taking
     into account the geographic location of the Employees); and (ii)
     participation in incentive compensation arrangements consistent with the
     incentive compensation arrangements of employees of Caldera in comparable
     positions. This Section 11.1(b) shall not be construed to create any third
     party beneficiary rights or any other rights of any kind in any Designated
     Employee and no Designated Employee shall have any cause of action as a
     third party beneficiary. Such offers of employment that will be extended by
     Newco to Employees will be on the same basis of time commitment (full or
     part time) as such Employee was employed immediately prior to the Effective
     Time. In addition, SCO shall cause the termination of any Potential
     Employees of the Contributed Companies who are not Designated Employees
     prior to the Effective Time. Unless the parties otherwise agree, on the
     date of the Closing, SCO shall notify each Employee who accepts an offer of
     employment extended by Newco as of the Effective Time, in a writing
     reasonably satisfactory to Newco, that such Employee's employment with SCO
     or any of its direct or indirect subsidiaries is then terminated. For a
     period of two years from the Closing Date, neither SCO nor any of its
     subsidiaries nor any of its employees may employ, make offers of employment
     to or otherwise solicit any of the employees of Newco or any of its
     subsidiaries as of the date hereof or any of the Designated Employees.

          (f) Severance.  SCO shall be responsible for any and all severance
     that may become due as a result of the transaction contemplated by this
     Agreement for all employees except for those Employees hired by Newco
     pursuant to Section 11.1(b); provided, however, that if Caldera does not
     make a reasonable offer of employment to a Designated Employee then Caldera
     shall be responsible for any and all severance that may become due as a
     result of the transaction or the termination of such employee.

     11.2  Termination of Employment.

          (a) SCO agrees to comply with the provisions of the WARN Act and any
     other federal, state, provincial or local or foreign statute or regulation
     or EU Directive regulation regarding termination of employment, plant
     closing or layoffs and to perform all obligations required of SCO with
     respect to the cessation of any operations of the Group Business or any
     other business of SCO or its subsidiaries, or the termination,
     re-assignment, re-location or change in position as terms and conditions of
     employment of any Employee (or other employee of them) who does not accept
     Newco's offer of employment.

          (b) In the United States, SCO shall (i) provide continuation health
     care coverage to all employees of the Group Business and their qualified
     beneficiaries who incur a qualifying event prior to the Effective Time, who
     are not given offers of employment by Newco or who do not accept Newco's
     offer of employment pursuant to Section 11.1(b) in accordance with the
     continuation health care coverage requirements of COBRA and (ii) provide
     COBRA continuation coverage to any former
                                      A-51
<PAGE>   300

     employee of the Contributed Company Group who was previously employed in
     the Group Business (collectively, the "Former Employees") and its qualified
     beneficiaries to whom, at the Effective Time, such continuation coverage
     was being provided or to whom SCO was under an obligation to provide such
     continuation coverage at the election of such Former Employee or qualified
     beneficiary.

     11.3  Cooperation.  SCO, Caldera and Newco agree, for themselves and its
affected subsidiaries, to cooperate fully with respect to the actions which are
necessary or reasonably desirable to accomplish the transactions contemplated
hereunder, including, without limitation, the provision of records and
information as each may reasonably request and in order to meet the notification
and consultation requirements of the Acquired Rights Directive in accordance
with the relevant regulations or laws adopting such directive in all relevant
jurisdictions, or any other similar notification and consultation obligation the
making of all appropriate filings under ERISA and the Internal Revenue Code.

     12. Tax Matters.

     12.1  Transaction Taxes; Representation; Transaction Tax Indemnity.  SCO
and Caldera shall bear equally any and all sales, use, excise, value added,
registration, stamp, property, documentary, transfer, withholding and similar
taxes, levies and duties (including all real estate transfer taxes, but not any
real estate transfer taxes that would be triggered as a result of a change in
control of a corporation) incurred, or that may be payable to any taxing
authority, with respect to the sale, transfer, or delivery of the Contributed
Stock and Assets and the assumption of the Assumed Liabilities, including any
such taxes, levies and duties imposed in connection with such transactions
(collectively, "Transaction Taxes"); provided, however, that Caldera shall not
be responsible for any Transaction Taxes in excess of $300,000. Newco and SCO
agree to cooperate in minimizing the amount of any Transaction Taxes and in the
filing of all necessary documentation and all Tax returns, reports and forms
("Returns") with respect to all Transaction Taxes, including any available
pre-sale filing procedures.

     Notwithstanding any other provision of this Agreement, the Unixware source
code, object code and related documentation ("Unixware Software") or other
software shall remain the property of SCO until (i) expeditiously delivered to
Newco at SCO's facility in Murray Hill, New Jersey, (ii) transferred by remote
telecommunication from SCO's place of business, to or through Newco's computer
with no tangible personal property transferred to Newco, such as storage media,
except for user manuals, or (iii) installed by SCO on Newco's computer without
the transfer of title or possession of storage media or any tangible personal
property other than user manuals. Newco agrees that it will not transfer the
Unixware Software or other software on tangible media into California.

     12.2  Treatment of Indemnity Payments.  All payments made by SCO or Newco,
as the case may be, to or for the benefit of the other party pursuant to any
indemnification obligations under this Agreement shall, to the extent
appropriate under applicable Tax law, be treated for Tax purposes as adjustments
to the value of the Contributed Stock and Contributed Assets.

     12.3  Indemnity for Taxes.

          (a) Except as otherwise provided in this Section 12.3, from and after
     the Closing, SCO shall timely pay and indemnify and save Newco and its
     Affiliates and Caldera harmless from any liability for, or arising out of
     or based upon, or relating to any Tax (including, without limitation, any
     obligation to contribute to the payment of a Tax determined on a
     consolidated basis or otherwise with respect to a group of corporations
     that includes or included SCO) (i) of SCO or any member of the affiliated
     group of corporation (as defined in Section 1504 of the Code or otherwise)
     of which SCO is a member (other than any member of the Contributed Company
     Group or with respect to any Tax relating to the income, business, assets,
     property or operations of the Group Business) for any taxable period; (ii)
     relating to the income, business, assets, property or operations of the
     Group Business or of the Contributed Company Group to the extent that such
     liability for Tax is not reflected in the SCO Disclosure Letter or the
     Group Financial Statements and is either (A) in respect of any taxable
     period that ends prior to the Closing Date or in respect of any taxable
     period that includes, but does not end on the Closing Date, the portion of
     such period ending on the Closing Date or (B) with
                                      A-52
<PAGE>   301

     respect to an excess loss account in the stock of any Contributed Company
     or from a deferred intercompany transaction (including any such transaction
     resulting from a distribution or deemed distribution of Newco Common Stock
     by any Contributing Company) entered into on or prior to the Closing Date
     and is triggered as a result of the Contributed Company Group ceasing to be
     affiliated with SCO; (iii) under Subpart F of the Code attributable to
     transactions undertaken by SCO or any of its affiliates before or after the
     Effective Time; or (iv) as a result of a breach of any representation,
     warranty, covenant or agreement made herein by SCO.

          (b) Notwithstanding anything contained in this Section 12.3(b), SCO
     shall not be obligated to indemnify Newco for any Tax (including, without
     limitation, any obligation to contribute to the payment of a Tax determined
     on a consolidated basis with respect to a group of corporations that
     includes or included SCO) by reason of an election or deemed election
     (including any protective election) with respect to transactions described
     in this Agreement made or filed post-Closing by Newco or any member of the
     Contributed Companies under Section 338 of the Internal Revenue Code.
     Further, no Section 338 election shall be made with respect to any of the
     transactions described in this Agreement.

          (c) Except to the extent otherwise provided in this Section 12.3(c),
     Newco shall timely pay and indemnify and save SCO and its Affiliates
     harmless from any liability for, or arising out of or based upon or
     relating to any Tax (including, without limitation, any obligation to
     contribute to the payment of a Tax determined on a consolidated basis with
     respect to a group of corporations that includes or included SCO) (i)
     relating to the income, business, assets, property or operations of the
     Group Business by Newco and its Affiliates or any member of the Contributed
     Company Group in respect of all taxable periods beginning after the Closing
     Date, or, in the case of any taxable period that includes but does not end
     on the Closing Date, the portion of such period commencing on the day
     following the Closing Date; (ii) to the extent such liability for Tax is
     reflected in the Group Financial Statements or the SCO Disclosure Letter
     and such liability is for Tax relating to the income, business, assets,
     property or operations of the Group Business or of any member of the
     Contributed Company Group; (iii) under Subpart F of the Code attributable
     to transactions undertaken by Newco or Caldera or any of their Affiliates
     after the Effective Time; or (iv) as a result of a breach of any
     representation, warranty, covenant or agreement made herein by Newco,
     Caldera or Merger Sub.

          (d) If, as a result of any action, suit, investigation, audit, claim,
     assessment or amended Tax Return, there is any change after the Closing
     Date in an item of income, gain, loss, deduction or credit that results in
     an increase in a Tax liability for which SCO would otherwise be liable
     pursuant to paragraph (a) of this Section 12.3, and such change results in
     a decrease in the Tax liability of Newco or any Affiliate or successor
     thereof for any taxable year or period beginning after the Closing Date or
     for the portion of any Straddle Period beginning after the Closing Date
     (assuming for purposes of this sentence that Newco and its Affiliates are
     liable for income tax at the highest applicable corporate federal, state,
     local and/or foreign rates), SCO shall not be liable pursuant to such
     paragraph (a) with respect to such increase to the extent of such decrease.
     If, as a result of any action, suit, investigation, audit, claim,
     assessment or amended Tax Return, there is any change after the Closing
     Date in an increase in an item of income, gain, loss, deduction, or credit
     that results in an increase in a Tax liability for which Newco would
     otherwise be liable pursuant to paragraph (c) of this Section 12.3, and
     such change results in a decrease in the Tax liability of SCO or any
     Affiliate or successor thereof (other than Newco) for any taxable year or
     period ending on or before the Closing Date or for the portion of any
     Straddle Period ending on the Closing date (other than by reason of a
     carryback of losses or deductions), Newco shall not be liable pursuant to
     such paragraph (c) with respect to such increase to the extent of such
     decrease.

          (e) For purposes of this Section 12.3, it shall be assumed that SCO
     and its Affiliates are liable for income tax at the highest applicable
     corporate federal, state, local and/or foreign rates, without reduction on
     account of net operating losses or other tax attributes.

<PAGE>   302

     12.4  Other Tax Matters.

          (a) SCO, Newco and Caldera will cooperate fully with each other in
     connection with the preparation of all returns and reports of Taxes,
     information returns, and all audit examinations of, or claims or assertions
     against, any member of the Contributed Company Group, in each case
     including but not limited to the furnishing or making available of records,
     books of account or other materials and appropriate personnel necessary or
     helpful to the defense against the assertions of any taxing authority. SCO
     shall, within ninety days after the Effective Time, deliver to Newco a
     schedule listing the tax basis of each of the Contributed Stock and Assets,
     along with copies of supporting calculations, information and records.

          (b) Except as provided in Section 12.4(c), in the event and to the
     extent that SCO or any member of an affiliated group of corporations (as
     defined in Section 1504 of the Internal Revenue Code or otherwise) of which
     SCO is a member (other than any member of the Contributed Company Group)
     receives a refund or credit of Taxes for any taxable period that ends prior
     to the Effective Time or in respect of any period that includes, but does
     not end on, the Effective Time, the portion of such period ending on the
     Effective Time (the "Pre-Closing Period") which is attributable to the
     carry back of losses, credits or similar items from any Tax return of any
     member of the Contributed Company Group, and in any case, in respect of any
     taxable period that begins after the Effective Time or in respect of any
     period that includes, but does not end on the Effective Time, the portion
     of such period commencing on the day following the Effective Time (the
     "Post-Closing Period"), SCO shall pay to Newco, net of any additional Tax
     payable by SCO or its Affiliates by reason of such carryback, the amount of
     such refund or credit (including any interest received thereon) or Tax
     reduction. In the event that any refund or credit of Taxes or Tax
     reductions for which a payment has been made pursuant to this Section
     12.4(b) subsequently is reduced or disallowed, the Contributed Companies
     and Newco shall indemnify and hold harmless SCO and its Affiliates for any
     Tax liability, including interest and penalties, assessed by reason of such
     reduction or disallowance.

          (c) In the event that an indemnified party receives a refund or credit
     relating to Taxes for which the other party is required to indemnify the
     first party pursuant to Section 12.3 of this Agreement (including, but not
     limited to VAT refunds), such indemnified party agrees to pay to the
     indemnifying party the amount of such refund or credit (including any
     interest received thereon). In the event that any refund or credit of Taxes
     for which a payment has been made pursuant to this Section 12.4(c)
     subsequently is reduced or disallowed, the indemnifying party shall
     indemnify and hold harmless the indemnified party for any Tax liability,
     including interest and penalties, assessed by reason of such reduction or
     disallowance.

          (d) If any claim for Tax relating to the Group Business or the
     Contributed Company Group is asserted against SCO or any Affiliate for any
     Pre-Closing Period, SCO shall promptly notify Newco in writing of such
     fact. SCO and its duly appointed representatives shall have the sole right
     to negotiate, resolve, settle or contest any such claim for Tax; provided,
     however, that they shall deal fairly and in good faith with respect to any
     claim for Tax which would require a payment by Newco to SCO or its
     Affiliates under Section 12.3(c) or this Section 12.4 and provided further,
     that with respect to any claim which would require a payment by Newco or
     have a Material Adverse Effect on the Group Business, no settlement will be
     agreed to without Newco's prior written consent. Such consent shall not be
     unreasonably withheld. Newco shall bear the legal and accounting costs and
     expenses incurred in contesting a matter for which it has withheld its
     consent. If any claim for Tax relating to the Contributed Company Group for
     any Post-Closing Period comes to the attention of SCO, SCO will notify
     Newco promptly of such claims and will cooperate fully with Newco and the
     Contributed Company Group in the resolution of such claim. A failure to
     promptly notify pursuant to this Section 12.4(d) shall not preclude another
     party's indemnification obligation.

          (e) SCO shall prepare any Tax returns (including any amendments
     thereto) of the members of the Contributed Company Group for all taxable
     periods that end, with respect to the Contributed

                                      A-54
<PAGE>   303

     Company Group, on or before the Effective Time (including any short period
     ending on the Effective Time) and which are due either before or after the
     Effective Time and shall deliver to Newco for signing by the appropriate
     party and filing, any Tax returns of the members of the Contributed Company
     Group (including any amendments thereto) with respect to any such period
     that have not been filed prior to the Effective Time. SCO shall deliver any
     such tax return or the portion thereof relating to the Group Business to
     Newco at least fifteen days prior to the date such tax return is due to be
     filed (taking into account any applicable extensions). SCO shall report for
     federal income tax purposes the operations of the Group Business and the
     Contributed Company Group for any short period ending on the Effective
     Time, and shall be responsible for the filing of, the consolidated tax
     returns of SCO's consolidated group which will include the income of the
     Group Business and the Contributed Company Group through the Effective Time
     and Newco will pay to SCO any amounts relating to such tax returns required
     by Section 12.3(c) prior to the filing of such tax returns. In order
     appropriately to apportion any taxes relating to a period that includes
     (but that would not, but for this Section 12.4(e) end on the Effective
     Time), the parties hereto will, to the extent permitted by applicable law,
     elect with the relevant taxing authority to treat for all purposes the
     Effective Time as the last day of a taxable period of any member of the
     Contributed Company Group. SCO shall, in respect of such returns, and Newco
     and the Contributed Company Group for returns with respect to the
     Post-Closing Period shall determine the income, gain, expenses, losses,
     deductions and credits of the Group Business and the Contributed Company
     Group in a manner (i) consistent with prior practice and actual operations
     in a manner that apportions such income, gain, expenses, loss, deductions
     and credits equitably from period to period and (ii) consistent with prior
     years.

          (f) The provisions of this Section 12 with respect to the consolidated
     groups or consolidated returns that include SCO or its Affiliates other
     than a Contributed Company shall apply mutatis mutandis with respect to
     combined or unitary groups or returns thereof.

          (g) Newco and SCO shall make (or indemnify the payor against) payments
     of estimated taxes (including amounts due with extensions) for which they
     are responsible under this Agreement in a timely manner. A payment or
     indemnity obligation under this Section 12 which is not made or satisfied
     when due shall accrue interest at the rate applicable to late payments of
     the pertinent Tax. Notwithstanding anything in this Section 12 to the
     contrary, a party shall not have to bear the cost of a Tax liability more
     than once (e.g., a payment of an estimated tax shall be credited against
     any payment due when the return is filed).

          (h) Except as provided in paragraph 12.4(e), for purposes of
     allocating a Tax for which a party is otherwise responsible under Section
     12.3 or this Section 12.4, the portion of those Taxes that are attributable
     to the operations of the Group Business or of any member of the Contributed
     Company Group for a relevant period (the "Interim Period") shall be (i) in
     the case of a Tax that is not based on a net income, the total amount of
     such Tax for the Interim Period in question multiplied by a fraction, the
     numerator of which is the number of days in the Interim Period and the
     denominator of which is the total number of days in such period, and (ii)
     in the case of a Tax that is based on net income, the Tax that is due shall
     be an amount as equitably determined by the parties based upon a
     hypothetical closing of the books.

          (i) If Newco, a Contributed Company or any of its respective
     Affiliates receive any notice of the assertion of any Tax liability
     relating to a member of the Contributed Company Group for which SCO may be
     liable under this Agreement, Newco shall give prompt written notice thereof
     to SCO.

          (j) After the Closing, Newco and the Contributed Companies will
     provide reasonable access to all relevant Newco and Contributed Company
     Group books, records, agreements and memoranda, and provide such assistance
     to SCO as SCO and its Affiliates shall reasonably request, with respect to
     any federal, foreign, state, provincial or local Tax matters pertaining to
     the members of the Contributed Company Group for taxable periods or
     transactions on or prior to the Effective Time. Newco will notify SCO prior
     to disposition of such Tax records, if such disposition will take place
     within ten years after the Effective Time. After the Closing, the parties
     will provide reasonable access to all relevant

                                      A-55
<PAGE>   304

     SCO and Contributed Companies' books, records, agreements, memoranda and
     tax returns, and provide copies of such information and such assistance to
     the other party as it shall reasonably request, with respect to any
     federal, foreign, state, provincial or local Tax matters pertaining to the
     Contributed Assets and the Contributed Company Group for taxable periods or
     transactions on or prior to the Effective Time.

          (k) Notwithstanding anything in this Agreement to the contrary, SCO
     and Newco covenant and agree (unless there has been a final determination
     as defined in Section 1313(a) of the Code or any other event which
     conclusively establishes a contrary position) for all Tax purposes,
     including all Tax Returns and any Tax examinations, proceedings or
     controversies, to (and to cause any Affiliate or successor to its assets or
     businesses to) take each of the positions set forth below (and not to take
     any position inconsistent therewith) and to use good faith and reasonable
     best efforts to defend such positions:

             (i) The Merger (A) will qualify as a tax-free reorganization
        described in Section 368(a) of the Code and (B) when taken together with
        the SCO Transaction, will qualify as a tax free transfer of the stock of
        Caldera to Newco governed by Section 351(a) of the Code.

             (ii) The SCO Transaction will, when taken together with the Merger,
        qualify as a transfer of the Contributed Stock and Contributed Assets to
        Newco governed by Section 351 of the Code.

          (l) SCO and Newco agree to report to the other any communication from
     or with the Internal Revenue Service or any other Taxing Authority which
     relates in any way to the characterization of the transactions governed by
     this Agreement. Each of SCO and Newco will file with its Federal income tax
     return for the taxable year in which the Merger and SCO Transaction occurs
     (which tax return shall be timely filed) the information required by Treas.
     Reg. sec. 1.351-3 and 1.368-3 and to provide each other upon request with a
     statement to the effect that such party has complied with this requirement
     after filing. SCO, the Contributed Companies, and Newco also will maintain
     such permanent records as are required by Treas. Reg. sec. 1.351-3(c) and
     1.368-3.

          (m) Neither Caldera nor Newco has any plan or intention to terminate
     the existence of Newco; to dispose of the assets contributed to Newco,
     except in the ordinary course of business or in a contribution to the
     capital of a wholly-owned subsidiary of Newco; to reacquire any stock to be
     issued in the transactions contemplated by this Agreement; or to take any
     other action that would reasonably be expected to cause the Merger and the
     SCO Transaction not to be treated as a tax-free exchange under Section 351
     of the Code. Neither Caldera nor Newco knows of any plan or intention of
     any Caldera Significant Stockholder to dispose of any Newco shares issued
     in the transactions contemplated by this Agreement. SCO knows of no plan or
     intention to terminate the existence of Newco or to dispose of the assets
     contributed to Newco, except in the ordinary course of business or in a
     contribution to the capital of a wholly-owned subsidiary of Newco. SCO has
     no plan or intention to dispose of any Newco shares issued in the
     transactions contemplated by this Agreement, except for distributions of
     Newco stock to SCO's shareholders, or to take any other action that would
     reasonably be expected to cause the merger and the SCO Transaction not to
     be treated as an exchange under Section 351 of the Code.

     12.5  Tax Representations.  Newco, Caldera and the Caldera Significant
Stockholder covenant and represent that Caldera, Newco and the Caldera
Significant Stockholder shall make such representations and covenants as their
respective counsel shall reasonably request prior to the closing for purposes of
establishing the qualification under Section 351 of the SCO Transaction and the
qualification of the Merger as a Section 368 transaction. Any such
representations shall be considered to be part of this Section 12.5(a).

     13. Miscellaneous.

     13.1  Governing Law; Venue.

          (a) Governing Law.  The internal laws of the State of New York
     (irrespective of its choice of law principles) will govern the validity of
     this Agreement, the construction of its terms and the interpretation and
     enforcement of the rights and duties of the parties hereto, except that the
     fiduciary duties of the directors and managers of parties hereto and its
     Affiliates shall be governed by the law of the jurisdiction of such
     company's formation.

          (b) Venue.  The parties agree that any dispute regarding the
     interpretation or validity of, or otherwise arising out of this Agreement,
     shall be subject to the exclusive jurisdiction of the California State
     Courts in and for Santa Clara County, California or, in the event of
     federal jurisdiction, the United States District Court for the Northern
     District of California sitting in Santa Clara County, California, and each
     party hereby agrees to submit to the personal and exclusive jurisdiction
     and venue of such courts and not to seek the transfer of any case or
     proceeding out of such courts.

     13.2  Assignment; Binding upon Successors and Assigns.  None of the parties
hereto may assign any of its rights or obligations hereunder without the prior
written consent of the other parties hereto; provided, however, that the sale or
other transfer of the stock of any Contributing Company shall not be deemed an
assignment provided that this Agreement remains enforceable against the
Contributing Company after such stock sale or transfer. Subject to the preceding
sentence, this Agreement will be binding upon and inure to the benefit of the
parties hereto and its respective successors and permitted assigns.

     13.3  Severability.  If any provision of this Agreement, or the application
thereof, will for any reason and to any extent be invalid or unenforceable, the
remainder of this Agreement and application of such provision to other persons
or circumstances will be interpreted so as reasonably to effect the intent of
the parties hereto. The parties further agree to replace such void or
unenforceable provision of this Agreement with a valid and enforceable provision
that will achieve, to the greatest extent possible, the economic, business and
other purposes of the void or unenforceable provision.

     13.4  Counterparts.  This Agreement may be executed in any number of
counterparts, each of which will be an original as regards any party whose
signature appears thereon and all of which together will constitute one and the
same instrument. This Agreement will become binding when one or more
counterparts hereof, individually or taken together, will bear the signatures of
all the parties reflected hereon as signatories.

     13.5  Other Remedies.  Except as otherwise provided herein, any and all
remedies herein expressly conferred upon a party will be deemed cumulative with
and not exclusive of any other remedy conferred hereby or by law on such party,
and the exercise of any one remedy will not preclude the exercise of any other.
The parties agree that specific performance is an appropriate remedy for a
breach of its respective obligations under this Agreement.

     13.6  Amendment and Waivers.  Any term or provision of this Agreement may
be amended by the parties hereto at anytime by execution of an instrument in
writing signed on behalf of each of SCO and Caldera. At any time prior to the
Closing, the observance of any term of this Agreement may be waived (either
generally or in a particular instance and either retroactively or prospectively)
only by a writing signed by the party or parties to be bound thereby. The waiver
by a party of any breach hereof or default in the performance hereof will not be
deemed to constitute a waiver of any other default or any succeeding breach or
default. Delay in exercising any right under this Agreement shall not constitute
a waiver of such right. This Agreement may be amended by the parties hereto at
any time before or after approval of such party's stockholders, but, after such
approval, no amendment will be made which by applicable law requires the further
approval of a party's stockholders without obtaining such further approval.

     13.7  Expenses.  Except as herein expressly provided to the contrary in
this Agreement or the Ancillary Agreements, each party will bear its respective
fees and expenses incurred with respect to the negotiation, preparation and
performance of this Agreement and the transactions contemplated hereby.

part of this Agreement, the prevailing party will be entitled to recover, as an
element of the costs of suit and not as damages, reasonable attorneys' fees to
be fixed by the court (including, without limitation, costs, expenses and fees
on any appeal). The prevailing party will be entitled to recover its costs of
suit, regardless of whether such suit proceeds to final judgment.

     Interest, less (a) the number of shares of Newco Common Stock issuable upon
     exercise of the Replacement Options pursuant to Section 1.3(a)(iii) below
     multiplied by .75, (b) the number of shares of Newco Common Stock issuable
     upon exercise of the SCO Options assumed by Newco pursuant to Section
     1.3(a)(iii) below multiplied by .75 and (c) the Escrow Shares issued to SCO
     and placed directly into escrow by Caldera pursuant to Section 1.3(b)
     below, with such number of shares to be appropriately adjusted in the event
     of any Caldera stock split, stock combination, reclassification or other
     similar capital change (the "First SCO Certificate") and pay SCO cash
     consideration equal to seven million dollars ($7,000,000) (the "Cash
     Consideration"), by wire transfer of immediately available funds or upon
     the cancellation of SCO's outstanding indebtedness to Caldera.

          (iii) Assumption or Replacement of SCO Options. Prior to the Effective
     Time, each employee or consultant of SCO who is offered and accepts
     employment or a consulting position with New Caldera and who has then
     outstanding options to purchase shares of SCO Common Stock held by such
     Optionee (collectively, the "SCO Options")(consisting of all outstanding
     options granted under the stock option plans of SCO or the SCO
     Subsidiaries, and any individual non-plan options held by the Optionees)
     shall elect one of the following alternatives with respect to each grant of
     options held by such employee or consultant:

             (A) Each of the then outstanding SCO Options held by such employee
        or consultant may be cancelled and replaced with an option to purchase
        one share of Newco Common Stock for each two shares of SCO Common Stock
        ("Replacement Options") subject to an SCO Option at the Effective Time
        with an exercise price per share of Newco Common Stock equal to the fair
        market value of Newco Common Stock immediately after the Effective Time,
        rounded up to the nearest cent. The vesting schedule of employees and
        consultants electing this alternative shall be determined as follows:
        (i) the number of vested shares of common stock under the Replacement
        Option grant will equal the number of vested shares of common stock
        subject to the cancelled SCO option grant immediately prior to the
        Effective Time multiplied by 0.25 and (ii) the remaining unvested
        Replacement Options will vest over a period of months determined by the

                                      A-70
<PAGE>   319

        following equation: 48 months less the product of the number of months
        vested under the SCO option grant multiplied by 0.5; or

             (B) Each of the then outstanding SCO Options held by such employee
        or consultant may be assumed by Newco and converted into an option to
        purchase one share of Newco Common Stock for each two shares of SCO
        Common Stock subject to an SCO Option at the Effective Time (the "SCO
        Ratio") at an exercise price per share of Newco Common Stock equal to
        the exercise price per share of such assumed SCO Option immediately
        prior to the Effective Time divided by the SCO Ratio, rounded up to the
        nearest cent. Except as set forth in the preceding sentence, the term,
        exercisability, vesting schedule, and all other terms and conditions of
        the SCO Options will be unchanged and all references in any option
        agreement governing such option to SCO shall be deemed to refer to
        Newco, where appropriate; provided, however, that the outstanding SCO
        Options previously designated as "incentive stock options" under Section
        422 of the Internal Revenue Code may, as a result of the foregoing
        adjustments, be converted into non-statutory stock options. Continuous
        service as an employee or consultant with SCO or any of the SCO
        Subsidiaries will be credited to the Optionee for purposes of
        determining the number of shares of Newco Common Stock vested and
        exercisable under the assumed SCO Option after the Closing. If the
        foregoing calculation results in a Newco Option, which is issued for an
        SCO Option, being exercisable for a fraction of a share of Newco Common
        Stock, then the number of shares of Newco Common Stock subject to such
        option will be rounded down to the nearest whole number of shares, with
        no cash being payable for such resulting fractional share.

     2. Section 1.3(c) of the Agreement is hereby deleted in its entirety.

     3. Section 13.15 of the Agreement is hereby amended as follows:

          (a) The following definition is hereby amended in its entirety:
     "Caldera Percentage Interest" means 72% of the fully diluted equity
     interest in Newco (taking into account all options, warrants and
     convertible debentures on an as-converted basis except for any Replacement
     Options issued or SCO Options assumed pursuant to Section 1.3(a)(iii)).

          (b) The following definition is hereby added in its entirety:
     "Replacement Options" is defined in Section 1.3(a)(iii)(A).

          (c) The following definition is hereby amended in its entirety: "SCO
     Ratio" is defined in Section 1.3(a)(iii)(B).

     4. All references to the form of Sales Representative and Support
Agreement, attached as Exhibit 4.12 of the Agreement shall hereby be replaced by
references to the form of Sales Representative and Support Agreement attached
hereto as Exhibit 4.12A (the "Sales Representative Agreement") and the form of
Open Server Research and Development Agreement attached hereto as Exhibit 4.12B
(the "Open Server Agreement"). The Sales Representative Agreement and Open
Server Agreement shall be executed at the Effective Time.

Board of Directors
Caldera Systems, Inc.
240 West Center Street
Orem, UT 84057

Dear Members of the Board:

     We understand that Caldera Systems, Inc. ("Caldera"), Caldera Holding, Inc.
("Newco") and The Santa Cruz Operation, Inc. ("SCO") propose to enter into an
Agreement and Plan of Reorganization (the "Agreement") pursuant to which (i) a
newly-formed, wholly-owned subsidiary of Newco will be merged with and into
Caldera, with each share of Caldera common stock ("Caldera Common Stock") being
converted into one share (the "Caldera Ratio") of Newco common stock ("Newco
Common Stock") and (ii) SCO and certain of its subsidiaries will contribute
certain of their assets and liabilities and all of the capital stock of the
Contributed Companies (as defined in the Agreement) to Newco in exchange for A)
a 28% equity interest in Newco (on a fully-diluted basis, including Newco
options to be issued pursuant to the Agreement) and B) seven million dollars in
cash or the cancellation of SCO's outstanding indebtedness to Caldera under the
convertible promissory note in the amount of seven million dollars issued by SCO
to Caldera as to the date of the agreement. The transaction described in (ii)
above is referred to herein as the "SCO Transaction." It is intended that the
merger and exchange referred to above qualify as a reorganization and tax-free
exchange under the provisions of Section 368(a) and Section 351(a) of the
Internal Revenue Code, as applicable. The terms and conditions of the above-
described transaction (the "Transaction") are more fully detailed in the
Agreement.

     You have requested our opinion as to whether the Caldera Ratio is fair,
from a financial point of view, to holders of Caldera Common Stock.

     Broadview International LLC ("Broadview") focuses on providing merger and
acquisition advisory services to information technology ("IT"), communications
and media companies. In this capacity, we are continually engaged in valuing
such businesses, and we maintain an extensive database of IT, communications and
media mergers and acquisitions for comparative purposes. We are currently acting
as financial advisor to Caldera's Board of Directors and will receive a fee from
Caldera upon the successful conclusion of the Transaction.

     In rendering our opinion, we have, among other things:

          (1) reviewed the terms of a draft of the Agreement dated July 30, 2000
     furnished to us by Caldera's counsel on July 30, 2000 (which, for the
     purposes of this opinion, we have assumed, with your permission, to be
     identical in all material respects to the Agreement to be executed except
     that, we have assumed with your permission that the Group Business (as
     defined in the Agreement) includes, among other things, the professional
     services business of SCO and its subsidiaries);

          (2) reviewed the balance sheet relating to the Group Business as of
     March 31, 2000 prepared by SCO management and provided to us by Caldera
     management;

          (3) reviewed annual financial projections through October 31, 2001 for
     Newco assuming completion of the Transaction prepared and provided to us by
     Caldera management;

          (4) reviewed certain internal financial and operating information
     concerning the Group Business (without giving effect to the Transaction),
     including income statement projections through October 31, 2001 jointly
     prepared and provided to us by Caldera and SCO managements;

          (5) participated in discussions with SCO management concerning the
     operations, business strategy, financial performance and prospects for the
     Group Business;

          (6) discussed with SCO management its view of the strategic rationale
     for the Transaction;

          (7) compared certain aspects of the financial performance of the Group
     Business with public companies we deemed comparable;

          (8) analyzed available information, both public and private,
     concerning other mergers and acquisitions we believe to be comparable in
     whole or in part to the SCO Transaction;

          (9) reviewed i) Caldera's Prospectus on Form 424B4, including the
     audited financial statements of Caldera for its fiscal years ended October
     31, 1997, 1998, and 1999 included therein, and ii) Caldera's Form 10-Q for
     the period ended April 30, 2000, including the unaudited financial
     statements included therein;

          (10) reviewed certain internal financial and operating information
     concerning Caldera (without giving effect to the Transaction), including
     quarterly projections through October 31, 2001, relating to Caldera,
     prepared and furnished to us by Caldera management;

          (11) participated in discussions with Caldera management concerning
     the operations, business strategy, current financial performance and
     prospects for Caldera;

          (12) discussed with Caldera management its view of the strategic
     rationale for the Transaction;

          (13) reviewed the recent reported closing prices and trading activity
     for Caldera Common Stock;

          (14) compared certain aspects of the financial performance of Caldera
     with public companies we deemed comparable;

          (15) reviewed recent equity research analyst reports covering Caldera;

          (16) analyzed the anticipated effect of the Transaction on the future
     financial performance of Newco;

          (17) participated in discussions related to the Transaction with
     Caldera, SCO and their respective advisors; and

          (18) conducted other financial studies, analyses and investigations as
     we deemed appropriate for purposes of this opinion.

     In rendering our opinion, we have relied, without independent verification,
on the accuracy and completeness of all the financial and other information
(including without limitation the representations and warranties contained in
the Agreement) that was publicly available or furnished to us by Caldera or SCO.
With respect to the financial projections examined by us, we have assumed that
they were reasonably prepared and reflected the best available estimates and
good faith judgments of (i) management of Caldera as to the future performance
of Caldera and Newco and (ii) management of Caldera and SCO as to the future
performance of the Group Business.

     Based upon and subject to the foregoing, we are of the opinion that the
Caldera Ratio is fair, from a financial point of view, to holders of Caldera
Common Stock.

     For purposes of this opinion, we have assumed that neither Caldera nor SCO
is currently involved in any material transaction other than the Transaction,
other publicly announced transactions, other preliminary discussed transactions
confidentially disclosed to us, and those activities undertaken in the ordinary
course of conducting their respective businesses. Our opinion is necessarily
based upon market, economic, financial and other conditions as they exist and
can be evaluated as of the date of this opinion, and any change in such
conditions would require a reevaluation of this opinion. We express no opinion
as

to the price at which Caldera Common Stock or Newco Common Stock will trade at
any time in the future.

     This opinion speaks only as of the date hereof. It is understood that this
opinion is for the information of the Board of Directors of Caldera in
connection with its consideration of the Agreement and does not constitute a
recommendation to any Caldera stockholder as to how such stockholder should vote
on the Agreement. This opinion may not be published or referred to, in whole or
part, without our prior written permission, which shall not be unreasonably
withheld. Broadview hereby consents to references to and the inclusion of this
opinion in its entirety in the Prospectus/Proxy Statement to be distributed to
Caldera stockholders in connection with the Transaction.

                                            Sincerely,

                                            Broadview International LLC

The Board of Directors
The Santa Cruz Operation, Inc.
400 Encinal Street
Santa Cruz, CA 95060

Gentlemen:

     The Santa Cruz Operation, Inc., a California corporation ("SCO" or the
"Company") proposes to enter into an Agreement and Plan of Reorganization dated
as of August 1, 2000, among Caldera Systems, Inc., a Delaware corporation
("Caldera"), Caldera Holding, Inc., a Delaware corporation ("Newco") and SCO
(the "Agreement") pursuant to which, among other things, (i) a newly formed
wholly owned subsidiary of Newco will be merged with and into Caldera, with
Caldera being the surviving corporation in such merger (the "Merger"), and all
outstanding Caldera securities will be converted, on a share-for-share basis,
into Newco securities having identical rights, preferences and privileges as
such Caldera securities had immediately prior to the Merger, and with Newco
assuming any and all outstanding options and other rights to purchase shares of
capital stock of Caldera (ii) the Company and certain of its subsidiaries will
contribute (the "Contribution") to Newco (x) all of the capital stock of certain
subsidiaries of the Company (the "Contributed Companies") and (y) certain assets
of the Contributed Companies set forth in the Agreement in consideration for the
issuance by Newco to the Company of shares of common stock, $0.001 par value per
share, of Newco, (iii) Newco will assume all options to acquire capital stock of
the Company and (iv) Caldera, Newco and the Company will enter into the Sale
Representative and Support Agreement (the transactions described in clauses (i),
(ii), (iii) and (iv) being referred to herein as (the "Proposed Transaction").
As a result of the Proposed Transaction, upon completion thereof, the Company
will hold 28% of the capital stock of Newco on a fully diluted basis.

     You have requested our opinion as to the fairness from a financial point of
view to SCO of the consideration to be received by SCO in connection with the
Proposed Transaction. For purposes of this opinion, we have assumed that (i) the
Merger will qualify as a tax-free reorganization for Newco and Caldera under the
United States Internal Revenue Code of 1986, as amended (the "Code"), (ii) the
Contribution will qualify as a nonrecognition transfer for SCO and Newco under
the Code and (iii) the Proposed Transaction will be accounted for as a purchase.

services, is regularly engaged in the valuation of businesses and their

financial advisor to the Board of Directors of SCO in connection with the
Proposed Transaction, and we will receive a fee for our services, which include
the rendering of this opinion.

     In the past, we have provided investment banking and other financial
advisory services to SCO and have received fees for rendering these services. In
the ordinary course of business, Chase acts as a market maker and broker in the
publicly traded securities of SCO and receives customary compensation in
connection therewith, and also provides research coverage for SCO. In the
ordinary course of business, Chase actively trades in the equity and derivative
securities of SCO for its own account and for the accounts of its customers and,
accordingly, may at any time hold a long or short position in such securities.
Chase may in the future provide additional investment banking or other financial
advisory services to SCO.

     In connection with our review of the Proposed Transaction, and in arriving
at our opinion, we have, among other things:

          (i) reviewed the publicly available consolidated financial statements
     of Caldera for recent years and interim periods to date and certain other
     relevant financial and operating data of Caldera (including its capital
     structure) made available to us from published sources;

          (ii) reviewed certain publicly available projected financial and
     operating information relating to Caldera;

          (iii) discussed the business, financial condition and prospects of
     Caldera with certain members of senior management;

          (iv) reviewed the internal unaudited financial statements of the
     Contributed Companies for recent years and interim periods to date and
     certain other relevant financial data of the Contributed Companies made
     available to us from the internal records of SCO;

          (v) reviewed certain internal projected financial and operating
     information relating to the Contributed Companies prepared by the senior
     management of SCO;

          (vi) discussed the business, financial condition and prospects of the
     Contributed Companies with certain members of senior management;

          (vii) reviewed the recent reported prices and trading activity for the
     common stocks of Caldera and compared such information and certain
     financial information for Caldera and the Contributed Companies with
     similar information for certain other companies engaged in businesses we
     consider comparable;

          (viii) reviewed the financial terms, to the extent publicly available,
     of certain comparable merger and acquisition transactions;

          (ix) reviewed the Agreement dated August 1, 2000;

          (x) discussed the tax and accounting treatment of the Proposed
     Transaction with Caldera and Caldera's counsel and independent accountants;
     and

          (xi) performed such other analyses and examinations and considered
     such other information, financial studies, analyses and investigations and
     financial, economic and market data as we deemed relevant.

     In rendering our opinion, we have assumed and relied upon the accuracy and
completeness of all of the information concerning Caldera or the Contributed
Companies considered in connection with our review of the Proposed Transaction,
and we have not assumed any responsibility for independent verification of such
information. We have not prepared any independent valuation or appraisal of any
of

Page  3

the assets or liabilities of Caldera or the Contributed Companies, nor have we
conducted a physical inspection of the properties and facilities of either
company. With respect to the financial forecasts and projections made available
to us and used in our analysis, we have assumed that they reflect the best
currently available estimates and judgments of the expected future financial
performance of Caldera and the Contributed Companies. For purposes of this
opinion, we have assumed that neither Caldera nor the Contributed Companies is a
party to any pending transactions, including external financings,
recapitalizations or material merger discussions, other than the Proposed
Transaction and those activities undertaken in the ordinary course of conducting
their respective businesses. Our opinion is necessarily based upon market,
economic, financial and other conditions as they exist and can be evaluated as
of the date of this letter and any change in such conditions would require a
reevaluation of this opinion. We express no opinion as to the price at which
Newco common stock will trade subsequent to the Effective Time (as defined in
the Agreement). In rendering this opinion, we have assumed that the proposed
merger will be consummated substantially on the terms discussed in the
Agreement, without any waiver of any material terms or conditions by any party
thereto.

     It is understood that this letter is for the information of the Board of
Directors and may not be used for any other purpose without our prior written
consent; provided, however, that this letter may be reproduced in full in the
Proxy Statement/Prospectus. This letter does not constitute a recommendation to
any stockholder as to how such stockholder should vote on the Proposed
Transaction.

     Based upon and subject to the foregoing and after considering such other
matters as we deem relevant, we are of the opinion that, as of the date hereof,
the consideration to be received by SCO in the Proposed Transaction is fair to
SCO from a financial point of view. We express no opinion, however, as to the
adequacy of any consideration received in the Proposed Transaction by Caldera or
any of its affiliates.

                                            Very truly yours,

<PAGE>   328

                                   ARTICLE IV

                                 CAPITAL STOCK

     A. Classes of Stock.  The Corporation is authorized to issue two classes of
stock to be designated, respectively, "Common Stock" and "Preferred Stock." The
total number of shares which the Corporation is authorized to issue is
200,000,000 shares. 175,000,000 shares, par value $0.001 per share, shall be
Common Stock and 25,000,000 shares, par value $0.001 per share, shall be
Preferred Stock. The consideration for the issuance of the shares shall be paid
to or received by the Corporation in full before their issuance and shall not be
less than the par value per share. The number of authorized shares of Common
Stock may be increased or decreased (but not below the number of shares there of
then outstanding) by the affirmative vote of the holders of a majority of the
stock of the Corporation entitled to vote, irrespective of the provisions of
Section 242(b)(2) of the General Corporation Law of Delaware.

     B. Common Stock.

          (1) General.  All shares of Common Stock will be identical and will
     entitle the holders thereof to the same rights, powers and privileges. The
     rights, powers and privileges of the holders of the Common Stock are
     subject to and qualified by the rights of holders of any then outstanding
     Preferred Stock.

          (2) Dividends.  Dividends may be declared and paid on the Common Stock
     from funds lawfully available therefor as and when determined by the Board
     of Directors and subject to any preferential dividend rights of any then
     outstanding Preferred Stock.

          (3) Dissolution, Liquidation or Winding Up.  In the event of any
     dissolution, liquidation or winding up of the affairs of the Corporation,
     whether voluntary or involuntary, each issued and outstanding share of
     Common Stock shall entitle the holder thereof to receive an equal portion
     of the net assets of the Corporation available for distribution to the
     holders of Common Stock, subject to any preferential rights of any then
     outstanding Preferred Stock.

          (4) Voting Rights.  Except as otherwise required by law or this
     Amended and Restated Certificate of Incorporation, each holder of Common
     Stock shall have one vote in respect of each share of stock held of record
     by such holder on the books of the Corporation for the election of
     directors and on all matters submitted to a vote of stockholders of the
     Corporation. Except as otherwise required by law or provided herein,
     holders of Preferred Stock shall vote together with holders of Common Stock
     as a single class, subject to any special or preferential voting rights of
     any then outstanding Preferred Stock. There shall be no cumulative voting.

          (5) Redemption.  The Common Stock is not redeemable.

     C. Preferred Stock.  The Board of Directors is authorized, subject to
limitations prescribed by law, by the rules of a national securities exchange,
if applicable, and by the provisions of this ARTICLE IV, to provide for the
issuance of the shares of Preferred Stock in series, and by filing a certificate
pursuant to the applicable law of the State of Delaware, to establish from time
to time the number of shares to be included in each such series, and to fix the
designation, powers, preferences, and rights of the shares of each such series
and the qualifications, limitations or restrictions thereof.

     The authority of the Board with respect to each series shall include, but
not be limited to, determination of the following:

          (1) The number of shares constituting that series and the distinctive
     designation of that series;

          (2) The dividend rate on the shares of that series, whether dividends
     shall be cumulative, and, if so, from which date or dates, and the relative
     rights of priority, if any, of payment of dividends on shares of that
     series;

                                       D-2
<PAGE>   329

          (3) Whether that series shall have voting rights, in addition to the
     voting rights provided by law, and, if so, the terms of such voting rights;

          (4) Whether that series shall have conversion privileges, and, if so,
     the terms and conditions of such conversion, including provision for
     adjustment of the conversion rate in such events as the Board of Directors
     shall determine;

          (5) Whether or not the shares of that series shall be redeemable, and,
     if so, the terms and conditions of such redemption, including the date or
     dates upon or after which they shall be redeemable, and the amount per
     share payable in case of redemption, which amount may vary under different
     conditions and at different redemption dates;

          (6) Whether that series shall have a sinking fund for the redemption
     or purchase of shares of that series, and, if so, the terms and amount of
     such sinking fund;

          (7) The rights of the shares of that series in the event of voluntary
     or involuntary liquidation, dissolution or winding up of the Corporation,
     and the relative rights or priority, if any, of payment of shares of that
     series; and

          (8) Any other relative rights, preferences and limitations of that
     series.

     Dividends on outstanding shares of Preferred Stock shall be paid or
declared and set apart for payment before any dividends shall be paid or
declared and set apart for payment on the Common Stock with respect to the same
dividend period.

     If upon any voluntary or involuntary liquidation, dissolution or winding up
of the Corporation, the assets available for distribution to holders of shares
of Preferred Stock of all series shall be insufficient to pay such holders the
full preferential amount to which they are entitled, then such assets shall be
distributed ratably among the shares of all series of Preferred Stock in
accordance with the respective preferential amounts (including unpaid cumulative
dividends, if any) payable with respect thereto.

     D. Preemptive Rights.  No holder of any of the shares of any class or
series of stock or of options, warrants or other rights to purchase shares of
any class or series of stock or of other securities of the Corporation shall
have any preemptive right to purchase or subscribe for any unissued stock of any
class or series, or any unissued bonds, certificates of indebtedness, debentures
or other securities convertible into or exchangeable for stock of any class or
series or carrying any right to purchase stock of any class or series; but any
such unissued stock, bonds, certificates or indebtedness, debentures or other
securities convertible into or exchangeable for stock or carrying any right to
purchase stock may be issued pursuant to resolution of the Board of Directors of
the Corporation to such persons, firms, corporations or associations, whether or
not holders thereof, and upon such terms as may be deemed advisable by the Board
of Directors in the exercise of its sole discretion.

                                   ARTICLE V

                                   DIRECTORS

     A. Number.  The number of directors of the Corporation shall be such
number, not less than five (5) nor more than fifteen (15) (exclusive of
directors, if any, to be elected by holders of preferred stock of the
Corporation, voting separately as a class), as shall be set forth from time to
time in the Bylaws. Vacancies in the Board of Directors of the Corporation,
however caused, and newly created directorships shall be filled by a vote of a
majority of the directors then in office, whether or not a quorum, and any
director so chosen shall hold office for a term expiring at the annual meeting
of stockholders at which the term of the class to which the director has been
chosen expires and when the director's successor is elected and qualified.

     B. Removal of Directors.  Notwithstanding any other provisions of this
Certificate or the Bylaws of the Corporation, any director or the entire Board
of Directors of the Corporation may be removed, at any

                                       D-3
<PAGE>   330

time, but only for cause and only by the affirmative vote of the holders of not
less than a majority of the outstanding shares of capital stock of the
Corporation entitled to vote generally in the election of directors (considered
for this purpose as one class) cast at a meeting of the stockholders called for
that purpose. Notwithstanding the foregoing, whenever the holders of any one or
more series of preferred stock of the Corporation shall have the right, voting
separately as a class, to elect one or more directors of the Corporation, the
preceding provisions of this ARTICLE V shall not apply with respect to the
director or directors elected by such holders of Preferred Stock.

                                   ARTICLE VI

                              STOCKHOLDER MEETINGS

     Meetings of stockholders may be held within or without the State of
Delaware, as the Bylaws may provide. The books of the Corporation may be kept
(subject to any provision contained in the statutes) outside the State of
Delaware at such place or places as may be designated from time to time by the
Board of Directors or in the Bylaws of the Corporation. The stockholders of the
Corporation may not take any action by written consent in lieu of a meeting.

                                  ARTICLE VII

                       LIMITATION OF DIRECTORS' LIABILITY

     Except to the extent that the General Corporation Law of Delaware prohibits
the elimination or limitation of liability of directors for breaches of
fiduciary duty, no director of the Corporation shall be personally liable to the
Corporation or its stockholders for monetary damages for any breach of fiduciary
duty as a director, notwithstanding any provision of law imposing such
liability. If the General Corporation Law is amended after approval by the
stockholders of this ARTICLE VII to authorize corporate action further
eliminating or limiting the personal liability of directors, then the liability
of a director of the Corporation shall be eliminated or limited to the fullest
extent permitted by the General Corporation Law of the State of Delaware, as so
amended. No amendment to or repeal of this provision shall apply to or have any
effect on the liability or alleged liability of any director of the Corporation
for or with respect to any acts or omissions of such director occurring prior to
such amendment.

                                  ARTICLE VIII

                                INDEMNIFICATION

     The Corporation may, to the fullest extent permitted by Section 145 of the
General Corporation Law of Delaware, as amended from time to time, indemnify
each person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative, by reason of the fact that he is or
was, or has agreed to become, a director or officer of the Corporation, or is or
was serving, or has agreed to serve, at the request of the Corporation, as a
director, officer or trustee of, or in a similar capacity with, another
corporation, partnership, joint venture, trust or other enterprise (including
any employee benefit plan) (all such persons being referred to hereafter as an
"Indemnitee"), or by reason of any action alleged to have been taken or omitted
in such capacity, against all expenses (including attorneys' fees), judgments,
fines and amounts paid in settlement actually and reasonably incurred by him or
on his behalf in connection with such action, suit or proceeding and any appeal
therefrom.

     Indemnification may include payment by the Corporation of expenses in
defending an action or proceeding in advance of the final disposition of such
action or proceeding upon receipt of an undertaking by the Indemnitee to repay
such payment if it is ultimately determined that such person is not entitled to
indemnification under this ARTICLE VIII, which undertaking may be accepted
without reference to the financial ability of such person to make such
repayment.

                                       D-4
<PAGE>   331

     The Corporation shall not indemnify any such person seeking indemnification
in connection with a proceeding (or part thereof) initiated by such person
unless the initiation thereof was approved by the Board of Directors of the
Corporation.

     The indemnification rights provided in this ARTICLE VIII (i) shall not be
deemed exclusive of any other rights to which Indemnitees may be entitled under
any law, agreement or vote of stockholders or disinterested directors or
otherwise, and (ii) shall inure to the benefit of the heirs, executors and
administrators of such persons. The Corporation may, to the extent authorized
from time to time by its Board of Directors, grant indemnification rights to
other employees or agents of the Corporation or other persons serving the
Corporation and such rights may be equivalent to, or greater or less than, those
set forth in this ARTICLE VIII.

                                   ARTICLE IX

                              AMENDMENT OF BYLAWS

     In furtherance of and not in limitation of powers conferred by statute, the
Board of Directors of the Corporation is expressly authorized to adopt, repeal,
alter, amend and rescind the Bylaws of the Corporation by vote of a majority of
the Board of Directors. In addition, the Bylaws may be amended by the
affirmative vote of the holders of at least two-thirds of the outstanding shares
of voting stock of the Corporation entitled to vote at an election of directors.

                                   ARTICLE X

                            AMENDMENT OF CERTIFICATE

     The Corporation reserves the right to amend, alter, change or repeal any
provision contained in this Amended and Restated Certificate of Incorporation,
in the manner now or hereafter prescribed by statute and this Amended and
Restated Certificate of Incorporation, and all rights conferred upon
stockholders herein are granted subject to this reservation. Notwithstanding the
foregoing, the provisions set forth in ARTICLES V, VI, VII, VIII, IX and this
ARTICLE X may not be repealed, altered, amended or rescinded in any respect
unless the same is approved by the affirmative vote of the holders of not less
than two-thirds of the outstanding shares of capital stock of the Corporation
entitled to vote generally in the election of directors (considered for this
purpose as a single class) cast at a meeting of the stockholders called for that
purpose (provided that notice of such proposed repeal, alteration, amendment or
rescission is included in the notice of such meeting)."

     FOURTH: That said amendments were duly adopted in accordance with the
provisions of Section 242 and 245 of the General Corporation Law.

     IN WITNESS WHEREOF, this Amended and Restated Certificate of Incorporation
has been signed by the Chief Executive Officer and the Secretary of the
Corporation this           day of           2000.

brought before the meeting and the reasons for conducting such business at the

declare to the meeting and any such business not properly brought before the
meeting shall not be transacted. Notwithstanding the foregoing provisions of

at a duly called annual or special meeting in accordance with these Bylaws and
the Certificate of Incorporation.

     Section 1.  The number of directors of this corporation that shall
constitute the whole board shall be determined by resolution of the Board of
Directors; provided, however, that no decrease in the number of directors shall
have the effect of shortening the term of an incumbent director.

     Section 2.  Vacancies and newly created directorships resulting from any
increase in the authorized number of directors may be filled by a majority of
the directors then in office, even if less than a quorum, or by a sole remaining

no directors in office, then an election of directors may be held in the manner
provided by statute.

     Section 3.  The business of the corporation shall be managed by or under
the direction of its Board of Directors which may exercise all such powers of

be exercised or done by the stockholders.

     Section 10.  Unless otherwise restricted by the certificate of
incorporation or these bylaws, members of the Board of Directors, or any
committee designated by the Board of Directors, may participate in a meeting of
the Board of Directors, or any committee, by means of conference telephone or
similar communications equipment by means of which all persons participating in

if any, of attendance at each meeting of the Board of Directors and may be paid
a fixed sum for attendance at each meeting of the Board of Directors or a stated
salary as director. No such payment shall preclude any director from serving the
corporation in any other capacity and receiving compensation therefor. Members
of special or standing committees may be allowed like compensation for attending
committee meetings.

the Board of Directors at any regular or special meeting, pursuant to law.
Dividends may be paid in cash, in property, or in shares of the capital stock,
subject to the provisions of the certificate of incorporation.

     Section 2.  Before payment of any dividend, there may be set aside out of
any funds of the corporation available for dividends such sum or sums as the
directors from time to time, in their absolute discretion, think proper as a
reserve or reserves to meet contingencies, or for equalizing dividends, or for
repairing or maintaining any property of the corporation, or for such other
purposes as the directors shall think conducive to the interest of the
corporation, and the directors may modify or abolish any such reserve in the
manner in which it was created.

                                     CHECKS

shall be signed by such officer or officers or such other person or persons as

                                  FISCAL YEAR

     Section 4.  The fiscal year of the corporation shall be fixed by resolution

facsimile thereof to be impressed or affixed or reproduced or otherwise.

                                INDEMNIFICATION

     Section 6.  The corporation shall, to the fullest extent authorized under
the laws of the State of Delaware, as those laws may be amended and supplemented
from time to time, indemnify any director made, or threatened to be made, a
party to an action or proceeding, whether criminal, civil, administrative or
investigative, by reason of being a director of the corporation or a predecessor
corporation or, at the corporation's request, a director or officer of another
corporation, provided, however, that the corporation shall indemnify any such
agent in connection with a proceeding initiated by such agent only if such
proceeding was authorized by the Board of Directors of the corporation. The
indemnification provided for in this Section 6 shall: (i) not be deemed
exclusive of any other rights to which those indemnified may be entitled under
any bylaw, agreement or vote of stockholders or disinterested directors or
otherwise, both as to action in their official capacities and as to action in
another capacity while holding such office, (ii) continue as to a person who has
ceased to be a director, and (iii) inure to the benefit of the heirs, executors
and administrators of such a person. The corporation's obligation to provide
indemnification under this Section 6 shall be offset to the extent of any other
source of indemnification or any otherwise applicable insurance coverage under a
policy maintained by the corporation or any other person.

     Expenses incurred by a director of the corporation in defending a civil or
criminal action, suit or proceeding by reason of the fact that he is or was a
director of the corporation (or was serving at the corporation's request as a
director or officer of another corporation) shall be paid by the corporation in

                                       E-9
<PAGE>   341

advance of the final disposition of such action, suit or proceeding upon receipt
of an undertaking by or on behalf of such director to repay such amount if it
shall ultimately be determined that he is not entitled to be indemnified by the
corporation as authorized by relevant sections of the General Corporation Law of
Delaware. Notwithstanding the foregoing, the corporation shall not be required
to advance such expenses to an agent who is a party to an action, suit or
proceeding brought by the corporation and approved by a majority of the Board of
Directors of the corporation which alleges willful misappropriation of corporate
assets by such agent, disclosure of confidential information in violation of
such agent's fiduciary or contractual obligations to the corporation or any
other willful and deliberate breach in bad faith of such agent's duty to the
corporation or its stockholders.

     The foregoing provisions of this Section 6 shall be deemed to be a contract
between the corporation and each director who serves in such capacity at any
time while this bylaw is in effect, and any repeal or modification thereof shall
not affect any rights or obligations then existing with respect to any state of
facts then or theretofore existing or any action, suit or proceeding theretofore
or thereafter brought based in whole or in part upon any such state of facts.

     The Board of Directors in its discretion shall have power on behalf of the
corporation to indemnify any person, other than a director, made a party to any
action, suit or proceeding by reason of the fact that he, his testator or
intestate, is or was an officer or employee of the corporation.

     To assure indemnification under this Section 6 of all directors, officers
and employees who are determined by the corporation or otherwise to be or to
have been "fiduciaries" of any employee benefit plan of the corporation which
may exist from time to time, Section 145 of the General Corporation Law of
Delaware shall, for the purposes of this Section 6, be interpreted as follows:
an "other enterprise" shall be deemed to include such an employee benefit plan,
including without limitation, any plan of the corporation which is governed by
the Act of Congress entitled "Employee Retirement Income Security Act of 1974,"
as amended from time to time; the corporation shall be deemed to have requested
a person to serve an employee benefit plan where the performance by such person
of his duties to the corporation also imposes duties on, or otherwise involves
services by, such person to the plan or participants or beneficiaries of the
plan; excise taxes assessed on a person with respect to an employee benefit plan
pursuant to such Act of Congress shall be deemed "fines."

                                  ARTICLE VIII

                                   AMENDMENTS

     Section 1.  These bylaws may be altered, amended or repealed or new bylaws
may be adopted by the affirmative vote of holders of at least 66 2/3% vote of
the outstanding voting stock of the corporation. These bylaws may also be
altered, amended or repealed or new bylaws may be adopted by the Board of
Directors, when such power is conferred upon the Board of Directors by the
certificate of incorporation. The foregoing may occur at any regular meeting of
the stockholders or of the Board of Directors or at any special meeting of the
stockholders or of the Board of Directors if notice of such alteration,
amendment, repeal or adoption of new bylaws be contained in the notice of such
special meeting. If the power to adopt, amend or repeal bylaws is conferred upon
the Board of Directors by the certificate of incorporation it shall not divest
or limit the power of the stockholders to adopt, amend or repeal bylaws.

                       1999 OMNIBUS STOCK INCENTIVE PLAN

1. ESTABLISHMENT AND PURPOSE.

     There is hereby adopted the Caldera Systems, Inc. 1999 Omnibus Stock
Incentive Plan (the "Plan"). The Plan shall be the successor to the Caldera
Systems, Inc. 1998 Stock Option Plan (the "Predecessor Plan"). Upon adoption of
the Plan by the Board of Directors and approval of the Plan by the stockholders
of Caldera Systems, Inc. (the "Company"), no further awards shall be made under
the Predecessor Plan. If the Plan is not approved by the stockholders of the
Company, the Predecessor Plan shall remain in full force and effect. The Plan is
intended to promote the interests of the Company and the stockholders of the
Company by providing officers, other employees of the Company, directors who are
not employees of the Company, and other persons who are expected to make a
long-term contribution to the success of the Company with appropriate incentives
and rewards to encourage them to enter into and continue in the employ of the
Company and/or to acquire a proprietary interest in the long-term success of the
Company, thereby aligning their interest more closely to the interest of
stockholders.

the number and kind of shares of stock which may thereafter be issued in
connection with Incentive Awards, (ii) the number and kind of shares of stock
issued or issuable in respect of outstanding Incentive Awards, and (iii) the

settled for cash.

4. ADMINISTRATION OF THE PLAN.

     The Plan shall be administered by the Committee. The Committee shall have
the authority in its sole discretion, subject to and not inconsistent with the
express provisions of the Plan, to administer the Plan and to exercise all the

limitation, the authority to grant Incentive Awards; to determine the persons to
whom and the time or times at which Incentive Awards shall be granted; to
determine the type and number of Incentive Awards to be granted, the number of
shares of Stock to which an Award may relate and the terms, conditions,
restrictions and performance criteria relating to any Incentive Award; to
determine whether, to what extent, and under what circumstances an Incentive
Award may be settled, canceled, forfeited, exchanged, or surrendered; to subject
shares of Stock to which an Award may relate to rights of repurchase or rights
of refusal in favor of the Company under the circumstances and upon the terms
set forth in an Award Agreement; to make adjustments in the performance goals in
recognition of unusual or non-recurring events affecting the Company or the
financial statements of the Company (to the extent in accordance with Section
162(m)of the Code, if applicable), or in response to changes in applicable laws,
regulations, or accounting principles; to construe and interpret the Plan and
any Incentive Award; to prescribe, amend and rescind rules and regulations
relating to the Plan; to determine the terms and provisions of Award Agreements;
and to make all other determinations deemed necessary or advisable for the
administration of the Plan.

     The Committee may, in its absolute discretion, without amendment to the
Plan, (i) accelerate the date on which any Tandem SAR or Stand-Alone SAR or
Incentive Award relating to Phantom Stock granted under the Plan becomes
exercisable, waive or amend the operation of Plan provisions respecting

                                       F-4
<PAGE>   346

exercise after termination of employment or otherwise adjust any of the terms of
such Option or Stand-Alone SAR, and (ii) accelerate the Exercise Date or Issue
Date, or waive any condition imposed hereunder, with respect to any share of
Restricted Stock or Phantom Stock or otherwise adjust any of the terms
applicable to such share.

     No member of the Committee shall be liable for any action, omission or
determination relating to the Plan, and the Company shall indemnify and hold
harmless each member of the Committee and each other director or employee of the
Company to whom any duty or power relating to the administration or
interpretation of the Plan has been delegated against any cost or expense
(including counsel fees) or liability (including any sum paid in settlement of a
claim with the approval of the Committee) arising out of any action, omission or
determination relating to the Plan, if, in either case, such action, omission or
determination was taken or made by such member, director or employee in good
faith and in a manner such member, director or employee reasonably believed to
be in or not opposed to the best interests of the Company.

5. ELIGIBILITY.

     The persons who shall be eligible to receive Incentive Awards pursuant to
the Plan shall be such employees of the Company or its Subsidiaries (including
officers of the Company or its Subsidiaries, whether or not they are directors
of the Company or its Subsidiaries) as the Committee shall select from time to
time. Directors and others who are not employees or officers of the Company,
including persons who may be expected to make a contribution to the Company's
future success, shall also be eligible to receive Incentive Awards under the
Plan.

6. AWARDS UNDER THE PLAN; AWARD AGREEMENT.

     The Committee may grant Options, Tandem SARs, Stand-Alone SARs, shares of
Restricted Stock, shares of Phantom Stock and Stock Bonuses, in such amounts and
with such terms and conditions as the Committee shall determine, subject to the
provisions of the Plan.

     Each Incentive Award granted under the Plan (except an unconditional Stock
Bonus) shall be evidenced by an Award Agreement which shall contain such
provisions as the Committee may in its sole discretion deem necessary or
desirable. By accepting an Incentive Award, a Participant thereby agrees that
the award shall be subject to all of the terms and provisions of the Plan and
the applicable Award Agreement.

7. OPTIONS.

     (a) Identification of Options. Each Option shall be clearly identified in
the applicable Award Agreement as either an Incentive Stock Option or a
Non-Qualified Stock Option.

     (b) Exercise Price. Each Award Agreement with respect to an Option shall
set forth the amount (the "option exercise price") payable by the grantee to the
Company upon exercise of the Option. The option exercise price per share shall
be determined by the Committee but shall in no event be less than the Fair
Market Value of a share of Common Stock on the date the Option is granted.

     (c) Term and Exercise of Options.

             (1) Unless the applicable Award Agreement provides otherwise, an
        Option shall become cumulatively exercisable as to 25 percent of the
        shares covered thereby on each of the first, second, third and fourth
        anniversaries of the date of grant. The Committee shall determine the
        expiration date of each Option; provided, however, that no Incentive
        Stock Option shall be exercisable more than 10 years after the date of
        grant. Unless the applicable Award Agreement provides otherwise, no
        Option shall be exercisable prior to the first anniversary of the date
        of grant.

                                       F-5
<PAGE>   347

             (2) An Option may be exercised for all or any portion of the shares
        as to which it is exercisable, provided, that no partial exercise of an
        Option shall be for an aggregate exercise price of less than $1,000. The
        partial exercise of an Option shall not cause the expiration,
        termination or cancellation of the remaining portion thereof.

             (3) An Option shall be exercised by delivering notice to the
        Company's principal office, to the attention of its Secretary, no less
        than one business day in advance of the effective date of the proposed
        exercise. Such notice shall specify the number of shares of Common Stock
        with respect to which the Option is being exercised and the effective
        date of the proposed exercise and shall be signed by the Participant or
        other person then having the right to exercise the Option. Such notice
        may be withdrawn at any time prior to the close of business on the
        business day immediately preceding the effective date of the proposed
        exercise. Payment for shares of Common Stock purchased upon the exercise
        of an Option shall be made on the effective date of such exercise by one
        or a combination of the following means: (i) in cash, by certified
        check, bank cashier's check or wire transfer; (ii) by delivering a
        properly executed exercise notice to the Company together with a copy of
        irrevocable instructions to a broker to deliver promptly to the Company
        the amount of sale or loan proceeds to pay the full amount of the
        Purchase Price, (iii) by delivering shares of Common Stock owned by the
        Participant with appropriate stock powers, (iv) by electing to have the
        Company retain shares of Common Stock which would otherwise be issued on
        the exercise of the Option, or (v) any combination of the foregoing
        forms. In determining the number of shares of Common Stock necessary to
        be delivered to or retained by the Company, such shares shall be valued
        at their Fair Market Value as of the exercise date.

             (4) Certificates for shares of Common Stock purchased upon the
        exercise of an Option shall be issued in the name of the Participant or
        other person entitled to receive such shares, and delivered to the
        Participant or such other person as soon as practicable following the
        effective date on which the Option is exercised.

     (d) Limitations on Incentive Stock Options.

             (1) To the extent that the aggregate Fair Market Value of shares of
        Common Stock with respect to which Incentive Stock Options are
        exercisable for the first time by a Participant during any calendar year
        under the Plan and any other stock option plan of the Company (or any
        Subsidiary of the Company) shall exceed $100,000, or such higher value
        as may be permitted under Section 422 of the Code, such Options shall be
        treated as Non-Qualified Stock Options. Such Fair Market Value shall be
        determined as of the date on which each such Incentive Stock Option is
        granted.

             (2) No Incentive Stock Option may be granted to an individual if,
        at the time of the grant, such individual owns stock possessing more
        than ten percent of the total combined voting power of all classes of
        stock of the Company unless (i) the exercise price per share of such
        Incentive Stock Option is at least 110 percent of the Fair Market Value
        of a share of Common Stock at the time such Incentive Stock Option is
        granted and (ii) such Incentive Stock Option is not exercisable after
        the expiration of five years from the date such Incentive Stock Option
        is granted.

     (e) Effect of Termination of Employment.

             (1) Unless the applicable Award Agreement provides otherwise, in
        the event that the employment of a Participant with the Company or a
        Subsidiary of the Company shall terminate for any reason other than
        death, Disability or Cause, (i) Options granted to such Participant, to
        the extent that they are exercisable at the time of such termination,
        shall remain exercisable until the date that is ninety (90) days after
        such termination, on which date they shall expire, and (ii) Options
        granted to such Participant, to the extent that they were not
        exercisable at the time of such termination, shall expire at the close
        of business on the date of such termination. Notwithstanding the
        foregoing, no Option shall be exercisable after the expiration of its
        term.

                                       F-6
<PAGE>   348

             (2) Unless the applicable Award Agreement provides otherwise, in
        the event that the employment of a Participant with the Company or a
        Subsidiary of the Company shall terminate on account of the Disability
        or death of the Participant (i) Options granted to such Participant, to
        the extent that they were exercisable at the time of such termination,
        shall remain exercisable until the first anniversary of such
        termination, on which date they shall expire, and (ii) Options granted
        to such Participant, to the extent that they were not exercisable at the
        time of such termination, shall expire at the close of business on the
        date of such termination. Notwithstanding the foregoing, no Option shall
        be exercisable after the expiration of its term.

             (3) If a Participant's employment with the Company or a Subsidiary
        of the Company is terminated for Cause, all outstanding options granted
        to such Participant shall expire at the commencement of business on the
        date of such termination.

     (f) Effect of Change in Control.

        Upon the occurrence of a Change in Control, (i) Options granted to a
        Participant, to the extent that they were exercisable at the time of a
        Change in Control, shall remain exercisable until their expiration
        notwithstanding the provisions of Section 7(e)(1) and (2) of the Plan,
        and (ii) Options granted to such Participant, to the extent they were
        not exercisable at the time of a Change in Control, shall expire at the

Non-Qualified Stock Option, subsequent to the time that, its related Option is
granted.

number of shares of Common Stock shall entitle the Participant to a cash
payment, for each such share, equal to the excess of (i) the Fair Market Value
of a share of Common Stock on the exercise date over (ii) the option exercise
price per share of the related Option. Such payment shall be made as soon as
practicable after the effective date of such exercise.

     (b) Term and Exercise of Tandem SAR.

          (1) A Tandem SAR shall be exercisable only if and to the extent that
     its related Option is exercisable.

          (2) The exercise of a Tandem SAR with respect to a number of shares of
     Common Stock shall cause the immediate and automatic cancellation of its
     related Option with respect to an equal number of shares. The exercise of
     an Option, or the cancellation, termination or expiration of an Option
     (other than pursuant to this Section 8(b)(2)), with respect to a number of
     shares of Common Stock shall cause the automatic and immediate cancellation
     of any related Tandem SARs to the extent that the number of shares of
     Common Stock remaining subject to such Option is less than the number of
     shares then subject to such Tandem SAR.

     Such Tandem SARs shall be canceled in the order in which they become
     exercisable.

          (3) A Tandem SAR may be exercised for all or any portion of the shares
     as to which the related Option is exercisable; provided, that no partial
     exercise of a Tandem SAR shall be for less than a number of shares having
     an aggregate option exercise price of less than $1,000. The partial
     exercise of a Tandem SAR shall not cause the expiration, termination or
     cancellation of the remaining portion thereof.

                                       F-7
<PAGE>   349

          (4) No Tandem SAR shall be assignable or transferable otherwise than
     together with its related Option, and any such transfer or assignment will
     be subject to the provisions of Section 20 of the Plan.

          (5) A Tandem SAR shall be exercisable by delivering notice to the
     Company's principal office, to the attention of its Secretary, no less than
     one business day in advance of the effective date of the proposed exercise.
     Such notice shall specify the number of shares of Common Stock with respect
     to which the Tandem SAR is being exercised and the effective date of the
     proposed exercise and shall be signed by the Participant or other person
     then having the right to exercise the Option to which the Tandem SAR is
     related. Such notice may be withdrawn at any time prior to the close of
     business on the business day immediately preceding the effective date of
     the proposed exercise.

9. STAND-ALONE SARS.

     (a) Benefit Upon Exercise.

        The exercise of a Stand-Alone SAR with respect to any number of shares
        of Common Stock shall entitle the Participant to a cash payment, for
        each such share, equal to the excess of (i) the Fair Market Value of a
        share of Common Stock on the exercise date over (ii) the Reference Value
        of the Stand-Alone SAR. Such payments shall be made as soon as
        practicable after the effective date of such exercise.

     (b) Term and Exercise of Stand-Alone SARs.

             (1) Unless the applicable Award Agreement provides otherwise, a
        Stand-Alone SAR shall become cumulatively exercisable as to 25 percent
        of the shares covered thereby on each of the first, second, third and
        fourth anniversaries of the date of grant. The Committee shall determine
        the expiration date of each Stand-Alone SAR. Unless the applicable Award
        Agreement provides otherwise, no Stand-Alone SAR shall be exercisable
        prior to the first anniversary of the date of grant.

             (2) A Stand-Alone SAR may be exercised for all or any portion of
        the shares as to which it is exercisable; provided, that no partial
        exercise of a Stand-Alone SAR shall be for an aggregate Reference Value
        of less than $1,000. The partial exercise of a Stand-Alone SAR shall not
        cause the expiration, termination or cancellation of the remaining
        portion thereof.

             (3) A Stand-Alone SAR shall be exercised by delivering notice to
        the Company's principal office, to the attention of its Secretary, no
        less than one business day in advance of the effective date of the
        proposed exercise. Such notice shall specify the number of shares of
        Common Stock with respect to which the Stand-Alone SAR is being
        exercised, and the effective date of the proposed exercise, and shall be
        signed by the Participant. The Participant may withdraw such notice at
        any time prior to the close of business on the business day immediately
        preceding the effective date of the proposed exercise.

     (c) Effect of Termination of Employment. The provisions set forth in
Section 7(e) with respect to the exercise of Options following termination of
employment shall apply as well to the exercise of Stand-Alone SARs.

     (d) Effect of Change in Control. Upon the occurrence of a Change in
Control, (i) Stand-Alone SARs granted under the Plan, to the extent exercisable
at the time of a Change of Control, shall remain exercisable until their
expiration notwithstanding the provisions of Section 7(e) of the Plan which are
incorporated into this Section 9, and (ii) Stand-Alone SARs not exercisable at
the time of a Change in Control shall expire at the close of business on the
date of such Change in Control.

10. RESTRICTED STOCK.

     (a) Issue Date and Vesting Date. At the time of the grant of shares of
Restricted Stock, the Committee shall establish an Issue Date or Issue Dates and
a Vesting Date or Vesting Dates with respect to such shares. The Committee may
divide such shares into classes and assign a different Issue Date and/or Vesting
Date for each class. If the grantee is employed by the Company or a Subsidiary
of the Company on an Issue Date (which may be the date of grant), the specified
number of shares of Restricted Stock shall be issued in accordance with the
provisions of Section 10(e) of the Plan. Provided that all conditions to the
vesting of a share of Restricted Stock imposed pursuant to Section 10(b) of the
plan are satisfied, and except as provided in Section 10(g) of the Plan, upon
the occurrence of the Vesting Date with respect to a share of Restricted Stock,
such share shall vest and the restrictions of Section 10(c) of the Plan shall
lapse.

     (b) Conditions to Vesting. At the time of the grant of shares of Restricted
Stock, the Committee may impose such restrictions or conditions to the vesting
of such shares as it, in its absolute discretion, deems appropriate.

     (c) Restrictions on Transfer Prior to Vesting. Prior to the vesting of a
share of Restricted Stock, no transfer of a Participant's rights with respect to
such share, whether voluntary or involuntary, by operation of law or otherwise,
shall be permitted. Immediately upon any attempt to transfer such rights, such
share, and all of the rights related thereto, shall be forfeited by the
Participant.

     (d) Dividends on Restricted Stock. The Committee in its discretion may
require that any dividends paid on shares of Restricted Stock shall be held in
escrow until all restrictions on such shares have lapsed.

     (e) Issuance of Certificates.

          (1) Reasonably promptly after the Issue Date with respect to shares of
     Restricted Stock, the Company shall cause to be issued a stock certificate,
     registered in the name of the Participant to whom such shares were granted,
     evidencing such shares; provided, that the Company shall not cause such a
     stock certificate to be issued unless it has received a stock power duly
     endorsed in blank with respect to such shares. Each such stock certificate
     shall bear the following legend: The transferability of this certificate
     and the shares of stock represented hereby are subject to the restrictions,
     terms and conditions (including forfeiture provisions and restrictions
     against transfer) contained in the 1999 Omnibus Stock Incentive Plan of
     Caldera Systems, Inc. and an Award Agreement entered into between the
     registered owner of such shares and Caldera Systems, Inc. A copy of such
     Plan and Award Agreement is on file in the office of the Secretary of
     Caldera Systems, Inc., 240 West Center Street, Orem, Utah 84057. Such
     legend shall not be removed until such shares vest pursuant to the terms of
     the applicable Award Agreement.

          (2) Each certificate issued pursuant to this Section 10(e), together
     with the stock powers relating to the shares of Restricted Stock evidenced
     by such certificate, shall be held by the Company unless the Committee
     determines otherwise.

     (f) Consequences of Vesting. Upon the vesting of a share of Restricted
Stock pursuant to the terms of the applicable Award Agreement, the restrictions
of Section 10(c) of the Plan shall lapse, except as otherwise provided in the
Award Agreement. Reasonably promptly after a share of Restricted Stock vests,
the Company shall cause to be delivered to the Participant to whom such shares
were granted, a certificate evidencing such share, free of the legend set forth
in Section 10(e) of the Plan.

     (g) Effect of Termination of Employment.

          (1) Subject to such other provision as the Committee may set forth in
     the applicable Award Agreement, and to the Committee's amendment authority
     pursuant to Section 4 of the Plan, upon the termination of a Participant's
     employment by the Company or any Subsidiary of the Company for any reason
     other than Cause, any and all shares to which restrictions on
     transferability apply shall be immediately forfeited by the Participant and
     transferred to the Company, provided that if the

                                       F-9
<PAGE>   351

     Committee, in its sole discretion and within thirty (30) days after such
     termination of employment notifies the Participant in writing of its
     decision not to terminate the Participant's rights in such shares, then the
     Participant shall continue to be the owner of such shares subject to such
     continuing restrictions as the Committee may prescribe in such notice. If
     shares of Restricted Stock are forfeited in accordance with the provision
     of this Section 10, the Company shall also have the right to require the
     return of all dividends paid on such shares, whether by termination of any
     escrow arrangement under which such dividends are held or otherwise.

          (2) In the event of the termination of a Participant's employment for
     Cause, all shares of Restricted Stock granted to such Participant which
     have not vested as of the date of such termination shall immediately be
     returned to the Company, together with any dividends paid on such shares.

     (h) Effect of Change in Control. Upon the occurrence of a Change in
Control, all restrictions on outstanding vested shares shall immediately lapse
and all outstanding shares of Restricted Stock which have not theretofore vested
shall immediately expire and be cancelled.

     (i) Special Provisions Regarding Restricted Stock Awards. Notwithstanding
anything to the contrary contained herein, Restricted Stock granted pursuant to
this Section 10 shall be based on the attainment by the Company (or a Subsidiary
or division of the Company if applicable) of performance goals pre-established
by the Committee, based on one or more of the following criteria: (i) the
attainment of a specified percentage return on total stockholder equity of the
Company; (ii) the attainment of a specified percentage increase in earnings per
share of Common Stock; (iii) the attainment of a specified percentage increase
in net income of the Company; and (iv) the attainment of a specified percentage
increase in profit before taxation of the Company (or a Subsidiary or division
of the Company if applicable). Attainment of any such performance criteria shall
be determined in accordance with generally accepted accounting principles as in
effect from time to time. Such shares of Restricted Stock shall be released from
restrictions only after the attainment of such performance measures have been
certified by the Committee.

11. PHANTOM STOCK.

     (a) Vesting Date. At the time of the grant of shares of Phantom Stock, the
Committee shall establish a Vesting Date or Vesting Dates with respect to such
shares. The Committee may divide such shares into classes and assign a different
Vesting Date for each class. Provided that all conditions to the vesting of a
share of Phantom Stock imposed pursuant to Section 11(c) of the Plan are
satisfied, and except as provided in Section 11(d) of the Plan, upon the
occurrence of the Vesting Date with respect to a share of Phantom Stock, such
share shall vest.

     (b) Benefit Upon Vesting. Upon the vesting of a share of Phantom Stock, the
Participant shall be entitled to receive in cash, within 30 days of the date on
which such share vests, an amount equal to the sum of (i) the Fair Market Value
of a share of Common Stock on the date on which such share of Phantom Stock
vests and (ii) the aggregate amount of cash dividends paid with respect to a
share of Common Stock during the period commencing on the date on which the
share of Phantom Stock was granted and terminating on the date on which such
share vests.

     (c) Conditions to Vesting. At the time of the grant of shares of Phantom
Stock, the Committee may impose such restrictions or conditions to the vesting
of such shares as it, in its absolute discretion, deems appropriate.

     (d) Effect of Termination of Employment.

          (1) Subject to such other provisions as the Committee may set forth in
     the applicable Award Agreement, and to the Committee's amendment authority
     pursuant to Section 4 of the Plan, shares of Phantom Stock that have not
     vested, together with any dividends credited on such shares, shall be
     forfeited upon the Participant's termination of employment for any reason
     other than Cause.

                                      F-10
<PAGE>   352

          (2) In the event of the termination of a Participant's employment for
     Cause, all shares of Phantom Stock granted to such Participant which have
     not vested as of the date of such termination shall immediately be
     forfeited, together with any dividends credited on such shares.

     (e) Effect of Change in Control. Upon the occurrence of a Change in
Control, all outstanding shares of Phantom Stock which have not theretofore
vested shall immediately expire and be cancelled.

     (f) Special Provisions Regarding Phantom Stock Awards. Notwithstanding
anything to the contrary contained herein, Phantom Stock granted pursuant to
this Section 11 to Executive Officers shall be based on the attainment by the
Company (or a Subsidiary or division of the Company if applicable) of
performance goals pre-established by the Committee, based on one or more of the
following criteria: (i) the attainment of a specified percentage return on total
stockholder equity of the Company; (ii) the attainment of a specified percentage
increase in earnings per share of Common Stock from continuing operations; (iii)
the attainment of a specified percentage increase in net income of the Company;
and (iv) the attainment of a specified percentage increase in profit before
taxation of the Company (or a Subsidiary or division of the Company if
applicable). Attainment of any such performance criteria shall be determined in
accordance with generally accepted accounting principles as in effect from time
to time. No cash payment in respect of any Phantom Stock award will be paid to
an Executive Officer until the attainment of the respective performance measures
have been certified by the Committee.

12. STOCK BONUSES.

     In the event that the Committee grants a Stock Bonus, a certificate for the
shares of Common Stock comprising such Stock Bonus shall be issued in the name
of the Participant to whom such grant was made and delivered to such Participant
as soon as practicable after the date on which such Stock Bonus is payable.

13. RIGHTS AS A STOCKHOLDER.

     No person shall have any rights as a stockholder with respect to any shares
of Common Stock covered by or relating to any Incentive Award until the date of
issuance of a stock certificate with respect to such shares. Except as otherwise
expressly provided in Section 3(c) of the Plan, no adjustment to any Incentive
Award shall be made for dividends or other rights for which the record date
occurs prior to the date such stock certificate is issued.

14. NO SPECIAL EMPLOYMENT RIGHTS; NO RIGHT TO INCENTIVE AWARD.

     Nothing contained in the Plan or any Award Agreement shall confer upon any
Participant any right with respect to the continuation of employment by the
Company or any Subsidiary of the Company or interfere in any way with the right
of the Company or any Subsidiary of the Company, subject to the terms of any
separate employment agreement to the contrary, at any time to terminate such
employment or to increase or decrease the compensation of the Participant. No
person shall have any claim or right to receive an Incentive Award hereunder.
The Committee's granting of an Incentive Award to a Participant at any time
shall neither require the Committee to grant any other Incentive Award to such
Participant or other person at any time or preclude the Committee from making
subsequent grants to such Participant or any other person.

15. SECURITIES MATTERS.

     (a) The Company shall be under no obligation to effect the registration
pursuant to the Securities Act of any interests in the Plan or any shares of
Common Stock to be issued hereunder or to effect similar compliance under any
state laws. Notwithstanding anything herein to the contrary, the Company shall
not be obligated to cause to be issued or delivered any certificates evidencing
shares of Common Stock pursuant to the Plan unless and until the Company is
advised by its counsel that the issuance and delivery of such certificates is in
compliance with all applicable laws, regulations of governmental authority and
the

                                      F-11
<PAGE>   353

requirements of any securities exchange on which shares of Common Stock are
traded. The Committee may require, as a condition of the issuance and delivery
of certificates evidencing shares of Common Stock pursuant to the terms hereof
and of the applicable Award Agreement, that the recipient of such shares make
such covenants, agreements and representations, and that such certificates bear
such legends, as the Committee, in its sole discretion, deems necessary or
desirable.

     (b) The transfer of any shares of Common Stock hereunder shall be effective
only at such time as counsel to the Company shall have determined that the
issuance and delivery of such shares is in compliance with all applicable laws,
regulations of governmental authority and the requirements of any securities
exchange on which shares of Common Stock are traded. The Committee may, in its
sole discretion, defer the effectiveness of any transfer of shares of Common
Stock hereunder in order to allow the issuance of such shares to be made
pursuant to registration or an exemption from registration or other methods for
compliance available under federal or state securities laws. The Committee shall
inform the Participant in writing of its decision to defer the effectiveness of
a transfer. During the period of such deferral in connection with the exercise
of an Option, the Participant may, by written notice, withdraw such exercise and
obtain the refund of any amount paid with respect thereto.

16. WITHHOLDING TAXES.

     Whenever cash is to be paid pursuant to an Incentive Award, the Company
shall have the right to deduct therefrom an amount sufficient to satisfy any
federal, state and local withholding tax requirements related thereto. Whenever
shares of Common Stock are to be delivered pursuant to an Incentive Award, the
Company shall have the right to require the Participant to remit to the Company
in cash an amount sufficient to satisfy any federal, state and local withholding
tax requirements related thereto. With the approval of the Committee, a
Participant may satisfy the foregoing requirement by electing to have the
Company withhold from delivery shares of Common Stock having a fair market value
equal to the amount of tax to be withheld. Such shares shall be valued at their
Fair Market Value on the date on which the amount of tax to be withheld is
determined (the "Tax Date"). Fractional share amounts shall be settled in cash.
Such a withholding election may be made with respect to all or any portion of
the shares to be delivered pursuant to an Incentive Award.

17. NOTIFICATION OF ELECTION UNDER SECTION 83(B) OF THE CODE.

     If any Participant shall, in connection with the acquisition of shares of
Common Stock under the Plan, make the election permitted under Section 83(b) of
the Code (i.e., an election to include in gross income in the year of transfer
the amounts specified in Section 83(b)), such Participant shall notify the
Company of such election within 10 days of filing notice of the election with
the Internal Revenue Service, in addition to any filing and a notification
required pursuant to regulation issued under the authority of Code Section
83(b).

18. NOTIFICATION UPON DISQUALIFYING DISPOSITION UNDER SECTION 421(B) OF THE
CODE.

     Each Award Agreement with respect to an Incentive Stock Option shall
require the Participant to notify the Company of any disposition of shares of
Common Stock issued pursuant to the exercise of such Option under the
circumstances described in Section 421(b) of the Code (relating to certain
disqualifying dispositions), within 10 days of such disposition.

19. AMENDMENT OR TERMINATION OF THE PLAN.

     The Board of Directors may, at any time, suspend or terminate the Plan or
revise or amend it in any respect whatsoever; provided, however, that
stockholder approval shall be required if and to the extent the Board of
Directors determines that such approval is appropriate for purposes of
satisfying Section 162(m) or 422 of the Code or to the extent such approval is
required by the rules of any stock exchange on which the Common Stock is listed.
Nothing herein shall restrict the Committee's ability to exercise its
discretionary authority pursuant to Section 4 of the Plan, which discretion may
be exercised without

                                      F-12
<PAGE>   354

amendment to the Plan. No action hereunder may, without the consent of a
Participant, reduce the Participant's rights under any outstanding Incentive
Award.

20. TRANSFERS UPON DEATH; NON-ASSIGNABILITY.

     Upon the death of a Participant, outstanding Incentive Awards granted to
such Participant may be exercised only by the executor or administrator of the
Participant's estate or by a person who shall have acquired the right to such
exercise by will or by the laws of descent and distribution. No transfer of an
Incentive Award by will or the laws of descent and distribution shall be
effective to bind the Company unless the Committee shall have been furnished
with (a) written notice thereof and with a copy of the will and/or such evidence
as the Committee may deem necessary to establish the validity of the transfer
and (b) an agreement by the transferee to comply with all the terms and
conditions of the Incentive Award that are or would have been applicable to the
Participant and to be bound by the acknowledgments made by the Participant in
connection with the grant of the Incentive Award.

     During a Participant's lifetime, the Committee may permit the transfer,
assignment or other encumbrance of an outstanding Option or outstanding shares
of Restricted Stock unless such Option is an Incentive Stock Option and the
Committee and the Participant intend that it shall retain such status.
Notwithstanding the foregoing, subject to any conditions as the Committee may
prescribe, a Participant may, upon providing written notice to the Secretary of
the Company, elect to transfer any or all Options granted to such Participant
pursuant to the Plan to members of his or her immediate family, including, but
not limited to, children, grandchildren and spouse or to trusts for the benefit
of such immediate family members or to partnerships in which such family members
are the only partners; provided, however, that no such transfer by any
Participant may be made in exchange for consideration.

21. EXPENSES AND RECEIPTS.

     The expenses of the Plan shall be paid by the Company. Any proceeds
received by the Company in connection with any Incentive Award will be used for
general corporate purposes.

22. FAILURE TO COMPLY.

     In addition to the remedies of the Company elsewhere provided for herein,
failure by a Participant (or beneficiary or transferee) to comply with any of
the terms and conditions of the Plan or the applicable Award Agreement, unless
such failure is remedied by such Participant (or beneficiary or transferee)
within ten days after notice of such failure by the Committee, shall be grounds
for the cancellation and forfeiture of such Incentive Award, in whole or in
part, as the Committee, in its absolute discretion, may determine.

23. EFFECTIVE DATE AND TERM OF PLAN.

     The Plan became effective on the Effective Date, but the Plan (and any
grants of Incentive Awards made prior to stockholder approval of the Plan) shall
be subject to the requisite approval of the stockholders of the Company. In the
absence of such approval, such Incentive Awards shall be null and void. Unless
earlier terminated by the Board of Directors, the right to grant Incentive
Awards under the Plan will terminate on the tenth anniversary of the Effective
Date. Incentive Awards outstanding at Plan termination will remain in effect
according to their terms and the provisions of the Plan.

24. APPLICABLE LAW.

     Except to the extent preempted by any applicable federal law, the Plan will
be construed and administered in accordance with the laws of the State of Utah,
without reference to the principles of conflicts of law.

                                      F-13
<PAGE>   355

25. PARTICIPANT RIGHTS.

     No Participant shall have any claim to be granted any Incentive Award under
the Plan, and there is no obligation for uniformity of treatment for
Participants. Except as provided specifically herein, a Participant or a
transferee of an Incentive Award shall have no rights as a stockholder with
respect to any shares covered by any award until the date of the issuance of a
Common Stock certificate to him for such shares.

26. UNFUNDED STATUS OF AWARDS.

     The Plan is intended to constitute an "unfunded" plan for incentive and
deferred compensation. With respect to any payments not yet made to a
Participant pursuant to an Incentive Award, nothing contained in the Plan or any
Award Agreement shall give any such Participant any rights that are greater than
those of a general creditor of the Company.

27. NO FRACTIONAL SHARES.

     No fractional shares of Common Stock shall be issued or delivered pursuant
to the Plan. The Committee shall determine whether cash, other Incentive Awards,
or other property shall be issued or paid in lieu of such fractional shares or
whether such fractional shares or any rights thereto shall be forfeited or
otherwise eliminated.

28. BENEFICIARY.

     A Participant may file with the Committee a written designation of a
beneficiary on such form as may be prescribed by the Committee and may, from
time to time, amend or revoke such designation. If no designated beneficiary
survives the Participant, the executor or administrator of the Participant's
estate shall be deemed to be the Participant's beneficiary.

29. INTERPRETATION.

     The Plan is designed and intended to comply with Rule 16b-3 promulgated
under the Exchange Act and, with Section 162(m) of the Code, and all provisions
hereof shall be construed in a manner to so comply.

                                   BACKGROUND

     A. The Company has adopted the Caldera Systems, Inc. 1999 Omnibus Stock
Incentive Plan (the "1999 Plan") pursuant to which the Company may grant Options
and other Incentive Awards to employees, directors and certain consultants of
the Company and its subsidiaries. Capitalized terms used in this Amendment but
not defined herein have the meaning set forth in the 1999 Plan.

     B. The Company desires to amend the 1999 Plan in order to increase the
number of shares of Common Stock reserved for issuance under the 1999 Plan.

                                   AMENDMENT

     NOW, THEREFORE, the 1999 Plan is hereby amended as follows:

          1. INCREASE IN NUMBER OF SHARES SUBJECT TO THE PLAN AND INDIVIDUAL
     LIMITATION.

          The first sentence of Section 3(a) of the Plan is hereby deleted in
     its entirety, and the following is hereby inserted in its stead:

             Subject to adjustment under Section 3(c) below, the maximum number
        of shares of Common Stock that may be issued under the Plan shall be
        4,105,238 shares.

          2. RATIFICATION. Except as specifically modified hereby, the Plan is
     hereby ratified and reaffirmed by the Company.

                                AMENDMENT NO. 3
                                       TO
                       1999 OMNIBUS STOCK INCENTIVE PLAN

     This Amendment No. 3 to the 1999 Omnibus Stock Incentive Plan (this
"Amendment") is executed by the undersigned, by and on behalf of Caldera
Systems, Inc., a Delaware corporation (the "Company").

                                   BACKGROUND

     A. The Company has adopted the Caldera Systems, Inc. 1999 Omnibus Stock
Incentive Plan (the "1999 Plan") pursuant to which the Company may grant Options
and other Incentive Awards to employees, directors and certain consultants of
the Company and its subsidiaries. Capitalized terms used in this Amendment but
not defined herein have the meaning set forth in the 1999 Plan.

     B. The Company desires to amend the 1999 Plan in order to incorporate a
formula award program pursuant to which directors of the Company will
automatically be granted 100,000 Non-Qualified Stock Options (vesting 50% on the
first anniversary of the date of grant and 50% on the second anniversary of the
date of grant) every two years.

                                   AMENDMENT

     NOW, THEREFORE, the 1999 Plan is hereby amended as follows:

          1. Director Formula Award Program. A new Section 30 is hereby added to
     the 1999 Plan, the content of which is as follows:

             SECTION 30. FORMULA AWARDS.

             30.1  General. The provisions of this Section 30 are applicable
        only to Options granted to directors of the Company ("Directors")
        pursuant to 30.2 below.

             30.2  Grants.

                (a) Initial Bi-Annual Grant. Subject to the limitations set
           forth in Section 30.8 and prior approval of this Amendment by the
           shareholders of the Company, Options to purchase 100,000 shares of
           Common Stock shall automatically be granted to each individual who is
           elected to serve or continues to serve as a Director following the
           date of the regularly scheduled annual meeting of shareholders of the
           Company (an "Annual Meeting") during the 2002 calendar year. Such
           Options shall be granted as of the date of such Annual Meeting, and
           the option exercise price for such Options shall be the Fair Market
           Value of a share of Common Stock on the date of grant. Such Options
           shall be exercisable 50% on the first anniversary of the date of
           grant and 50% on the second anniversary of the date of grant. No
           Options shall be granted under this provision if an Annual Meeting is
           not held during the 2002 calendar year.

                (b) Subsequent Bi-Annual Grants. Subject to the limitations set
           forth in Section 30.8 and prior approval of this Amendment by the
           shareholders of the Company, as of the date of each Annual Meeting
           held during any even-numbered calendar year beginning in 2004,
           Options to purchase 100,000 shares of Common Stock shall
           automatically be granted to each individual who is elected to serve
           or continues to serve as a Director following such Annual Meeting.
           The option exercise price for such Options shall be the Fair Market
           Value of a share of Common Stock on the date of grant. Such Options
           shall become exercisable 50% on the first anniversary of the date of
           grant and 50% on the second anniversary of the

                                       I-1
<PAGE>   359

           date of grant. No Options shall be granted under this provision if an
           Annual Meeting is not held during the respective even numbered year.

                (c) New Directors. Subject to the limitations set forth in
           Section 30.8 and prior approval of this Amendment by the shareholders
           of the Company, persons who are first elected or appointed to serve
           as a Director after the effective date of this Amendment shall
           automatically be granted Options to purchase a number of shares of
           Common Stock determined using the following formula:

<TABLE>
<S>                  <C>
                     Months X 100,000
Number of Options =  ----------------
                            24
</TABLE>

                Months -- the number of full calendar months between the date
           the Director's service as a Director commences and March 1 of the
           next even numbered year.

                Such Options shall be granted as of the date of commencement of
           the Director's service as a director, and the option exercise price
           for such Options shall be the Fair Market Value of a share of Common
           Stock on the date of grant. Any such Options shall become exercisable
           50% on the first anniversary of the date of date of grant and 50% on
           the second anniversary of the date of grant.

                (d) Top-Up Grant for Existing Directors. This subsection (d)
           applies to any directors whose Options are scheduled to vest
           completely prior to March 1, 2002. Subject to the limitations set
           forth in Section 30.8 and prior approval of this Section 30 by the
           shareholders of the Company, each such director shall automatically
           be granted Options to purchase a number of shares of Common Stock
           using the formula stated in subsection (c) above. Such Options shall
           be granted as of the first day of the month following the date on
           which the director's Options are schedule to fully vest, and the
           option exercise price for such Options shall be the Fair Market Value
           of a share of Common Stock on the date of grant. Any such options
           shall become exercisable 50% on the first anniversary of the date of
           grant and 50% on the second anniversary of the date of grant.

             30.3  Option Agreement. Each Option granted under this Section 30
        shall be evidenced by an Award Agreement duly executed on behalf of the
        Company and by the Director to whom such Option is granted and dated as
        of the applicable date of grant. All Options granted under this Section
        30 shall be Non-Qualified Stock Options unless, with respect to
        Directors who are also employees of the Company, the Committee
        determines, in its discretion before the date of grant, that some or all
        such Options shall be Incentive Stock Options.

             30.5  Method of Exercise And Payment. The method of exercise and
        payment of the exercise price for Options granted under this Section
        shall be as set forth in Section 7(c)(2)(3), and (4).

             30.6  Term of Formula Awards. Each Formula Award shall expire ten
        (10) years from its date of grant, but shall be subject to earlier
        termination as provided in Section 7(f) and Section 7(e), provided that
        references to termination of "employment" shall be deemed to refer to
        termination of "service as a director."

             30.7  Limitation as to Directorship. Neither this Section 30, nor
        the granting of a Formula Award, nor any other action taken pursuant to
        this Section 30, shall constitute or be evidence of any agreement or
        understanding, express or implied, that a Director has a right to
        continue as a Director for any period of time or at any particular rate
        of compensation. No Director shall have any right to be granted any
        Option under this Section 30 until such Option is deemed to have been
        granted under this Section 30, and the Board of Directors may amend or
        eliminate this Section 30 at any time for any reason.

             30.8  Termination of Formula Awards. Notwithstanding any provision
        to the contrary, no Option shall be granted pursuant to Section 30.2 on
        a date when the number of shares of

                                       I-2
<PAGE>   360

        Common Stock authorized for issuance pursuant to the Plan is less than
        the sum of (a) all shares of Common Stock issued upon the exercise of
        all Options granted under the Plan to date, (b) all shares of Common
        Stock subject to outstanding, unexpired Options, and (c) all Options
        that would, but for the effect of this provision, be granted pursuant to
        Section 30 on that date. In the event Options are not granted as a
        result of the application of this Section 30.8, no Options shall
        thereafter be granted pursuant to this Section 30 until the shareholders
        of the Company approve an amendment to the Plan increasing the number of
        shares of Common Stock available hereunder.

             30.9  Other Plan Provisions. All provisions of the Plan not
        inconsistent with this Section 30 shall apply to Options granted to
        Directors under this Section 30. In the event of any conflict between a
        provision of this Section 30 and a provision in any other Section of the
        Plan, such provision of this Section 30 shall be deemed to control with
        respect to Options granted under this Section 30.

          2. Ratification. Except as specifically modified hereby, the Plan is
     hereby ratified and reaffirmed by the Company.

          3. Effectiveness. This Amendment shall be effective on the date it is
     approved by the shareholders of the Company.

     The undersigned, who is the duly elected Secretary of the Company, hereby
certifies that, following approval of this Amendment by the Board of Directors
of the Company, the shareholders approved this amendment at a duly convened
meeting of the shareholders on             , 2000.

                       1999 OMNIBUS STOCK INCENTIVE PLAN

     This Amendment No. 4 to the 1999 Omnibus Stock Incentive Plan (this
"Amendment") is executed by the undersigned, by and on behalf of Caldera
Systems, Inc., a Delaware corporation (the "Company").

                                   BACKGROUND

     A. The Company has adopted the Caldera Systems, Inc. 1999 Omnibus Stock
Incentive Plan (the "1999 Plan") pursuant to which the Company may grant Options
and other Incentive Awards to employees, directors and certain consultants of
the Company and its subsidiaries. Capitalized terms used in this Amendment but
not defined herein have the meaning set forth in the 1999 Plan.

     B. The Company desires to amend the 1999 Plan in order to certain changes
and administrative clarifications to the 1999 Plan.

                                   AMENDMENT

     NOW, THEREFORE, the 1999 Plan is hereby amended as follows:

          1. Allow Grant of Non-Qualified Options with Exercise Price Below
     FMV. The second sentence of Section 7(b) of the 1999 Plan is amended to
     read as follows:

             The Option exercise price per share shall be set by the Committee
        in its discretion on a case by case basis, but in the case of an
        Incentive Stock Option shall not be less than the Fair Market Value of a
        share of Common Stock on the date of grant.

          2. Allow Exercise of Non-Qualified Options Up to 120 Days After
     Termination of Service. Clause (i) of Section 7(e)(1) of the 1999 Plan is
     amended to read as follows:

             (i) Options granted to such Participant, to the extent they are
        exercisable at the time of such termination, shall remain exercisable
        until the date which is 90 days (or 120 days in the case of a
        "Non-Qualified Stock Option")after the date of such termination, on
        which date they shall expire, and ...

          3. Allow Exercise of Options Up to 30 Days After Termination for
     Cause. Section 7(e)(3) of the 1999 Plan is amended to read as follows:

             (3) Unless an applicable Award Agreement issued after the date
        hereof provides otherwise, if a Participant's employment with the
        Company or a Subsidiary of the Company is terminated for Cause, Options
        granted to the Participant, to the extent they are then exercisable,
        shall remain exercisable for 30 days following the date of termination
        of employment, on which date they shall expire. Notwithstanding the
        foregoing, no Option shall be exercisable after expiration of its term.

          4. Allow Cash Out, Conversion or Other Disposition of Vested Options
     and SARS Upon Change in Control.

             (a) Section 7(f) of the 1999 Plan is amended to add the following
        sentences at the end thereof:

                Any vested, exercisable Options outstanding at the time of a
           Change in Control shall be cashed out, converted to options of the
           acquiring entity, assumed by the acquiring entity or otherwise
           disposed of in the manner provided in any shareholder-approved
           agreement or plan governing or providing for such Change in Control
           ("Change in Control Agreement");
                                       J-1
<PAGE>   362

           provided that any such cash-out, conversion, assumption or
           disposition of the Options shall not deprive the Option holder of the
           inherent value of his Options, measured solely by the excess of the
           Fair Market Value of the underlying Option shares immediately prior
           to the Change in Control over the Option exercise price, without the
           holder's consent. In the absence of such governing provisions in a
           Change in Control Agreement, the Committee in its sole discretion may
           on a case by case basis require any vested, exercisable Options that
           remain outstanding upon a Change in Control to be cashed out and
           terminated in exchange for a lump sum cash payment, shares of the
           acquiring entity or a combination thereof equal in value to the fair
           market value of the Option, measured in the manner described above,
           immediately prior to the Change in Control. Any non-vested Options
           shall terminate upon a Change in Control unless: (i) otherwise
           provided in the Change in Control Agreement or in a written agreement
           , such as a severance agreement, between the Company and the
           Participant; or (ii) the Committee in its sole discretion on a case
           by case basis elects in writing to waive termination

             (b) Section 9(d) of the 1999 Plan is amended to add the following
        sentence at the end thereof:

                Any vested, exercisable Non-Tandem SARs shall, upon a Change in
           Control, be cashed out, converted, assumed or otherwise disposed of
           in the same manner as applies to Options under Section 7(f).

          5. Provide Flexibility to Grant Restricted Stock and Phantom Stock
     Without Performance Guidelines.

             (a) Section 10(i) of the 1999 Plan is amended to read as follows:

                The Committee may designate on a case-by-case basis whether
           Restricted Stock Awards are intended to be "performance based
           compensation" within the meaning of Code Section 162(m). The grant of
           Restricted Stock so designated shall be based on the attainment by
           the Company (or a Subsidiary or division of the Company if
           applicable) of performance goals pre-established by the Committee,
           based on one or more of the following criteria: (i) the attainment of
           a specified percentage return on total stockholder equity of the
           Company; (ii) the attainment of a specified percentage increase in
           earnings per share of Common Stock; (iii) the attainment of a
           specified percentage increase in net income of the Company; and (iv)
           the attainment of a specified percentage increase in profit before
           taxation of the Company (or a Subsidiary or division of the Company
           if applicable). Attainment of any such performance criteria shall be
           determined in accordance with generally accepted accounting
           principles as in effect from time to time. Such shares shall be
           released from restrictions only after the attainment of such
           performance measures have been certified by the Committee.

             (b) Section 11(f) of the 1999 Plan is amended to read as follows:

                The Committee may designate on a case by case basis whether
           Phantom Stock Awards are intended to be "performance based
           compensation" within the meaning of Code Section 162(m). The grant of
           Phantom Stock so designated shall be based on the attainment by the
           Company (or a Subsidiary or division of the Company if applicable) of
           performance goals pre-established by the Committee, based on one or
           more of the following criteria: (i) the attainment of a specified
           percentage return on total stockholder equity of the Company; (ii)
           the attainment of a specified percentage increase in earnings per
           share of Common Stock; (iii) the attainment of a specified percentage
           increase in net income of the Company; and (iv) the attainment of a
           specified percentage increase in profit before taxation of the
           Company (or a Subsidiary or division of the Company if applicable).
           Attainment of any such performance criteria shall be determined in
           accordance with generally accepted accounting principles as in effect
           from time to time. Such shares shall be released from

                                       J-2
<PAGE>   363

           restrictions only after the attainment of such performance measures
           have been certified by the Committee.

     6. Technical Amendments.

          (a) The definition of "Participant" in Section 2(t) is hereby deleted,
     and the following is inserted in its stead:

             "Participant" means any person who is both eligible to receive an
        Incentive Award pursuant to the Plan (as set forth in Section 5) and to
        whom an Incentive Award is granted pursuant to the Plan, and, upon his
        or her death, his or her successors, heirs, executors and
        administrators, as the case may be.

          (b) Section 5 of the 1999 Plan is hereby deleted, and the following is
     inserted in its stead:

             5. Eligibility. The persons who shall be eligible to receive
        Incentive Awards pursuant to the Plan shall be all employees and
        directors of the Company and its Subsidiaries and such other persons
        whom the Committee determines are expected to make a contribution to the
        Company. The Committee may grant Incentive Awards to any, all or none of
        such eligible persons at any time, from time to time, during the term of
        the Plan.

          (c) A new Section 31 is hereby added to the 1999 Plan, the content of
     which is as follows:

             Any reference to "termination of employment," or words of similar
        import, in the Plan shall be deemed, (i) when applied to non-employee
        Directors, to mean "termination of service as a director," and (ii) when
        applied to employee-Directors, to mean "termination of service as an
        employee and a director." Reference to "termination of employment," or
        words of similar import, in the Plan shall not be deemed to apply to
        persons who were not employees or a director of the Company or a
        Subsidiary of the Company.

     7. Ratification. Except as specifically modified hereby, the Plan is hereby
ratified and reaffirmed by the Company.

     The undersigned, who is the duly elected Secretary of the Company, hereby
certifies that the Board of Directors of the Company approved this Amendment on
July 14, 2000, at which time this Amendment became effective.

                             CALDERA SYSTEMS, INC.
                          EMPLOYEE STOCK PURCHASE PLAN
         (AS AMENDED AND RESTATED EFFECTIVE AS OF              , 2000)

I. PURPOSE OF THE PLAN

     This Employee Stock Purchase Plan is intended to promote the interests of
Caldera Systems, Inc., a Delaware corporation, by providing eligible employees
with the opportunity to acquire a proprietary interest in the Corporation
through participation in a payroll-deduction based employee stock purchase plan
designed to qualify under Section 423 of the Code.

     Capitalized terms herein shall have the meanings assigned to such terms in
the attached Appendix.

II. ADMINISTRATION OF THE PLAN

     The Plan Administrator shall have full authority to interpret and construe
any provision of the Plan and to adopt such rules and regulations for
administering the Plan as it may deem necessary in order to comply with the
requirements of Section 423 of the Code. Decisions of the Plan Administrator
shall be final and binding on all parties having an interest in the Plan.

III. STOCK SUBJECT TO PLAN

     A. The stock purchasable under the Plan shall be shares of authorized but
unissued or reacquired Common Stock, including shares of Common Stock purchased
on the open market. The maximum number of shares of Common Stock which may be
issued in the aggregate under the Plan shall not exceed two million (2,000,000)
shares. Such share reserve includes (i) the 500,000 shares initially reserved
for issuance under the Plan plus (ii) the one million five hundred thousand
(1,500,000)-share increase authorized by the Board on                  , 2000
and subject to stockholder approval at the Special Meeting to be held on
                 , 2000.

     B. The number of shares of Common Stock available for issuance under the
Plan shall automatically increase on the first trading day of each calendar year
during the term of the Plan, beginning with the 2001 calendar year, by an amount
equal to one percent (1%) of the shares of Common Stock outstanding on the last
trading day of the immediately preceding calendar year, but in no event shall
such annual increase exceed Seven Hundred Fifty Thousand (750,000) shares.

     C. Should any change be made to the Common Stock by reason of any stock
split, stock dividend, recapitalization, combination of shares, exchange of
shares or other change affecting the outstanding Common Stock as a class without
the Corporation's receipt of consideration, appropriate adjustments shall be
made to (i) the maximum number and class of securities issuable under the Plan,
(ii) the maximum number and class of securities purchasable per Participant on
any one Purchase Date, (iii) the maximum number and class of securities
purchasable in total by all Participants on any one Purchase Date, (iv) the
maximum number and class of securities and the price per share in effect under
each outstanding purchase right in order to prevent the dilution or enlargement
of benefits thereunder.

IV. OFFERING PERIODS

     A. Shares of Common Stock shall be offered for purchase under the Plan
through a series of successive offering periods until such time as (i) the
maximum number of shares of Common Stock available for issuance under the Plan
shall have been purchased or (ii) the Plan shall have been sooner terminated.

     B. Each offering period shall be of such duration (not to exceed
twenty-four (24) months) as determined by the Plan Administrator prior to the
start date of such offering period. However, the initial
<PAGE>   365

offering period commenced at the Effective Time (March 20, 2000) and will
terminate on the last business day in April 2002. Subsequent offering periods
shall commence as designated by the Plan Administrator.

     C. Each offering period shall be comprised of a series of one or more
successive Purchase Intervals. Purchase Intervals shall run from the first
business day in May each year to the last business day in October of the same
year and from the first business day in November each year to the last business
day in April of the following year. However, the first Purchase Interval in
effect under the initial offering period commenced at the Effective Time and
will terminate on the last business day in October 2000.

     D. Should the Fair Market Value per share of Common Stock on any Purchase
Date within an offering period be less than the Fair Market Value per share of
Common Stock on the start date of that offering period, then that offering
period shall automatically terminate immediately after the purchase of shares of
Common Stock on such Purchase Date, and a new offering period shall commence on
the next business day following such Purchase Date. The new offering period
shall have a duration of twenty-four (24) months, unless a shorter duration is
established by the Plan Administrator within five (5) business days following
the start date of that offering period.

V. ELIGIBILITY

     A. Each individual who is an Eligible Employee on the start date of an
offering period under the Plan may enter that offering period on such start date
or on any subsequent Semi-Annual Entry Date within that offering period,
provided he or she remains an Eligible Employee.

     B. Each individual who first becomes an Eligible Employee after the start
date of an offering period may enter that offering period on any subsequent
Semi-Annual Entry Date within that offering period on which he or she is an
Eligible Employee.

     C. The date an individual enters an offering period shall be designated his
or her Entry Date for purposes of that offering period.

     D. To participate in the Plan for a particular offering period, the
Eligible Employee must complete the enrollment forms prescribed by the Plan
Administrator (including a stock purchase agreement and a payroll deduction
authorization) and file such forms with the Plan Administrator (or its
designate) on or before his or her scheduled Entry Date.

VI. PAYROLL DEDUCTIONS

     A. The payroll deduction authorized by the Participant for purposes of
acquiring shares of Common Stock during an offering period may be any multiple
of one percent (1%) of the Cash Earnings paid to the Participant during each
Purchase Interval within that offering period, up to a maximum of ten percent
(10%). The deduction rate so authorized shall continue in effect throughout the
offering period, except to the extent such rate is changed in accordance with
the following guidelines:

          (i) The Participant may, at any time during the offering period,
     reduce his or her rate of payroll deduction to become effective as soon as
     possible after filing the appropriate form with the Plan Administrator. The
     Participant may not, however, effect more than one (1) such reduction per
     Purchase Interval.

          (ii) The Participant may, prior to the commencement of any new
     Purchase Interval within the offering period, increase the rate of his or
     her payroll deduction by filing the appropriate form with the Plan
     Administrator. The new rate (which may not exceed the ten percent (10%)
     maximum) shall become effective on the start date of the first Purchase
     Interval following the filing of such form.

     B. Payroll deductions shall begin on the first pay day following the
Participant's Entry Date into the offering period and shall (unless sooner
terminated by the Participant) continue through the pay day ending with or
immediately prior to the last day of that offering period. The amounts so
collected shall be

                                       K-2
<PAGE>   366

credited to the Participant's book account under the Plan, but no interest shall
be paid on the balance from time to time outstanding in such account. The
amounts collected from the Participant shall not be required to be held in any
segregated account or trust fund and may be commingled with the general assets
of the Corporation and used for general corporate purposes.

     C. Payroll deductions shall automatically cease upon the termination of the
Participant's purchase right in accordance with the provisions of the Plan.

     D. The Participant's acquisition of Common Stock under the Plan on any
Purchase Date shall neither limit nor require the Participant's acquisition of
Common Stock on any subsequent Purchase Date, whether within the same or a
different offering period.

VII. PURCHASE RIGHTS

     A. Grant of Purchase Right.  A Participant shall be granted a separate
purchase right for each offering period in which he or she participates. The
purchase right shall be granted on the Participant's Entry Date into the
offering period and shall provide the Participant with the right to purchase
shares of Common Stock, in a series of successive installments over the
remainder of such offering period, upon the terms set forth below. The
Participant shall execute a stock purchase agreement embodying such terms and
such other provisions (not inconsistent with the Plan) as the Plan Administrator
may deem advisable.

     Under no circumstances shall purchase rights be granted under the Plan to
any Eligible Employee if such individual would, immediately after the grant, own
(within the meaning of Code Section 424(d)) or hold outstanding options or other
rights to purchase, stock possessing five percent (5%) or more of the total
combined voting power or value of all classes of stock of the Corporation or any
Corporate Affiliate.

     B. Exercise of the Purchase Right.  Each purchase right shall be
automatically exercised in installments on each successive Purchase Date within
the offering period, and shares of Common Stock shall accordingly be purchased
on behalf of each Participant (other than Participants whose payroll deductions
have previously been refunded pursuant to the Termination of Purchase Right
provisions below) on each such Purchase Date. The purchase shall be effected by
applying the Participant's payroll deductions for the Purchase Interval ending
on such Purchase Date to the purchase of whole shares of Common Stock at the
purchase price in effect for the Participant for that Purchase Date.

     C. Purchase Price.  The purchase price per share at which Common Stock will
be purchased on the Participant's behalf on each Purchase Date within the
offering period shall be equal to eighty-five percent (85%) of the lower of (i)
the Fair Market Value per share of Common Stock on the Participant's Entry Date
into that offering period or (ii) the Fair Market Value per share of Common
Stock on that Purchase Date.

     D. Number of Purchasable Shares.  The number of shares of Common Stock
purchasable by a Participant on each Purchase Date during the offering period
shall be the number of whole shares obtained by dividing the amount collected
from the Participant through payroll deductions during the Purchase Interval
ending with that Purchase Date by the purchase price in effect for the
Participant for that Purchase Date. However, the maximum number of shares of
Common Stock purchasable per Participant on any one Purchase Date shall not
exceed Seven Hundred Fifty (750) shares, subject to periodic adjustments in the
event of certain changes in the Corporation's capitalization. In addition, the
maximum number of shares of Common Stock purchasable in total by all
Participants on any one Purchase Date under the Plan shall not exceed One
Hundred Twenty-Five Thousand (125,000) shares, subject to periodic adjustments
in the event of certain changes in the corporation's capitalization. However,
the Plan Administrator shall have the discretionary authority, exercisable prior
to the start of any offering period under the Plan, to increase or decrease the
limitations to be in effect for the number of shares purchasable per Participant
and in total by all Participants on each Purchase Date during that offering
period.

                                       K-3
<PAGE>   367

     E. Excess Payroll Deductions.  Any payroll deductions not applied to the
purchase of shares of Common Stock on any Purchase Date because they are not
sufficient to purchase a whole share of Common Stock shall be held for the
purchase of Common Stock on the next Purchase Date. However, any payroll
deductions not applied to the purchase of Common Stock by reason of the
limitation on the maximum number of shares purchasable on the Purchase Date
shall be promptly refunded.

     F. Termination of Purchase Right.  The following provisions shall govern
the termination of outstanding purchase rights:

          (i) A Participant may, at any time prior to the next scheduled
     Purchase Date in the offering period, terminate his or her outstanding
     purchase right by filing the appropriate form with the Plan Administrator
     (or its designate), and no further payroll deductions shall be collected
     from the Participant with respect to the terminated purchase right. Any
     payroll deductions collected during the Purchase Interval in which such
     termination occurs shall, at the Participant's election, be immediately
     refunded or held for the purchase of shares on the next Purchase Date. If
     no such election is made at the time such purchase right is terminated,
     then the payroll deductions collected with respect to the terminated right
     shall be refunded as soon as possible.

          (ii) The termination of such purchase right shall be irrevocable, and
     the Participant may not subsequently rejoin the offering period for which
     the terminated purchase right was granted. In order to resume participation
     in any subsequent offering period, such individual must re-enroll in the
     Plan (by making a timely filing of the prescribed enrollment forms) on or
     before his or her scheduled Entry Date into that offering period.

          (iii) Should the Participant cease to remain an Eligible Employee for
     any reason (including death, disability or change in status) while his or
     her purchase right remains outstanding, then that purchase right shall
     immediately terminate, and all of the Participant's payroll deductions for
     the Purchase Interval in which the purchase right so terminates shall be
     immediately refunded. However, should the Participant cease to remain in
     active service by reason of an approved unpaid leave of absence, then the
     Participant shall have the right, exercisable up until the last business
     day of the Purchase Interval in which such leave commences, to (a) withdraw
     all the payroll deductions collected to date on his or her behalf for that
     Purchase Interval or (b) have such funds held for the purchase of shares on
     his or her behalf on the next scheduled Purchase Date. In no event,
     however, shall any further payroll deductions be collected on the
     Participant's behalf during such leave. Upon the Participant's return to
     active service (x) within ninety (90) days following the commencement of
     such leave or (y) prior to the expiration of any longer period for which
     such Participant's right to reemployment with the Corporation is guaranteed
     by either statute or contract, his or her payroll deductions under the Plan
     shall automatically resume at the rate in effect at the time the leave
     began, unless the Participant withdraws from the Plan prior to his or her
     return. An individual who returns to active employment following a leave of
     absence which exceeds in duration the applicable (x) or (y) time period
     will be treated as a new Employee for purposes of the Plan and must, in
     order to resume participation in the Plan, re-enroll in the Plan (by making
     a timely filing of the prescribed enrollment forms) on or before his or her
     scheduled Entry Date into the offering period.

     G. Change of Control.  Each outstanding purchase right shall automatically
be exercised, immediately prior to the effective date of any Change of Control,
by applying the payroll deductions of each Participant for the Purchase Interval
in which such Change of Control occurs to the purchase of whole shares of Common
Stock at a purchase price per share equal to eighty-five percent (85%) of the
lower of (i) the Fair Market Value per share of Common Stock on the
Participant's Entry Date into the offering period in which such Change of
Control occurs or (ii) the Fair Market Value per share of Common Stock
immediately prior to the effective date of such Change of Control. However, the
applicable limitation on the number of shares of Common Stock purchasable per
Participant shall continue to apply to any such purchase, but not the limitation
on the number of shares of Common Stock purchasable in total by all Participants
on any one Purchase Date.

                                       K-4
<PAGE>   368

     The Corporation shall use its best efforts to provide at least ten
(10)-days prior written notice of the occurrence of any Change of Control, and
Participants shall, following the receipt of such notice, have the right to
terminate their outstanding purchase rights prior to the effective date of the
Change of Control.

     H. Proration of Purchase Rights.  Should the total number of shares of
Common Stock to be purchased pursuant to outstanding purchase rights on any
particular date exceed the number of shares then available for issuance under
the Plan, the Plan Administrator shall make a pro-rata allocation of the
available shares on a uniform and nondiscriminatory basis, and the payroll
deductions of each Participant, to the extent in excess of the aggregate
purchase price payable for the Common Stock pro-rated to such individual, shall
be refunded.

     I. Assignability.  The purchase right shall be exercisable only by the
Participant and shall not be assignable or transferable by the Participant.

     J. Stockholder Rights.  A Participant shall have no stockholder rights with
respect to the shares subject to his or her outstanding purchase right until the
shares are purchased on the Participant's behalf in accordance with the
provisions of the Plan and the Participant has become a holder of record of the
purchased shares.

VIII. ACCRUAL LIMITATIONS

     A. No Participant shall be entitled to accrue rights to acquire Common
Stock pursuant to any purchase right outstanding under this Plan if and to the
extent such accrual, when aggregated with (i) rights to purchase Common Stock
accrued under any other purchase right granted under this Plan and (ii) similar
rights accrued under other employee stock purchase plans (within the meaning of
Code Section 423) of the Corporation or any Corporate Affiliate, would otherwise
permit such Participant to purchase more than Twenty-Five Thousand Dollars
($25,000) worth of stock of the Corporation or any Corporate Affiliate
(determined on the basis of the Fair Market Value per share on the date or dates
such rights are granted) for each calendar year such rights are at any time
outstanding.

     B. For purposes of applying such accrual limitations to the purchase rights
granted under the Plan, the following provisions shall be in effect:

          (i) The right to acquire Common Stock under each outstanding purchase
     right shall accrue in a series of installments on each successive Purchase
     Date during the offering period on which such right remains outstanding.

          (ii) No right to acquire Common Stock under any outstanding purchase
     right shall accrue to the extent the Participant has already accrued in the
     same calendar year the right to acquire Common Stock under one (1) or more
     other purchase rights at a rate equal to Twenty-Five Thousand Dollars
     ($25,000) worth of Common Stock (determined on the basis of the Fair Market
     Value per share on the date or dates of grant) for each calendar year such
     rights were at any time outstanding.

     C. If by reason of such accrual limitations, any purchase right of a
Participant does not accrue for a particular Purchase Interval, then the payroll
deductions which the Participant made during that Purchase Interval with respect
to such purchase right shall be promptly refunded.

     D. In the event there is any conflict between the provisions of this
Article and one or more provisions of the Plan or any instrument issued
thereunder, the provisions of this Article shall be controlling.

IX. EFFECTIVE DATE AND TERM OF THE PLAN

     A. The Plan was adopted by the Board on February 15, 2000 and became
effective at the Effective Time, provided no purchase rights granted under the
Plan shall be exercised, and no shares of Common Stock shall be issued
hereunder, until (i) the Plan shall have been approved by the stockholders of
the Corporation and (ii) the Corporation shall have complied with all applicable
requirements of the 1933 Act (including the registration of the shares of Common
Stock issuable under the Plan on a Form S-8

                                       K-5
<PAGE>   369

registration statement filed with the Securities and Exchange Commission), all
applicable listing requirements of any stock exchange (or the Nasdaq National
Market, if applicable) on which the Common Stock is listed for trading and all
other applicable requirements established by law or regulation. In the event
such stockholder approval is not obtained, or such compliance is not effected,
within twelve (12) months after the date on which the Plan is adopted by the
Board, the Plan shall terminate and have no further force or effect, and all
sums collected from Participants during the initial offering period hereunder
shall be refunded.

     B. Unless sooner terminated by the Board, the Plan shall terminate upon the
earliest of (i) the last business day in April 2010, (ii) the date on which all
shares available for issuance under the Plan shall have been sold pursuant to
purchase rights exercised under the Plan or (iii) the date on which all purchase
rights are exercised in connection with a Corporate Transaction. No further
purchase rights shall be granted or exercised, and no further payroll deductions
shall be collected, under the Plan following such termination.

X. AMENDMENT/TERMINATION OF THE PLAN

     A. The Board may alter, amend, suspend or terminate the Plan at any time to
become effective immediately following the close of any Purchase Interval.
However, the Plan may be amended or terminated immediately upon Board action, if
and to the extent necessary to assure that the Corporation will not recognize,
for financial reporting purposes, any compensation expense in connection with
the shares of Common Stock offered for purchase under the Plan, should the
financial accounting rules applicable to the Plan at the Effective Time be
subsequently revised so as to require the Corporation to recognize compensation
expense in the absence of such amendment or termination.

     B. In no event may the Board effect any of the following amendments or
revisions to the Plan without the approval of the Corporation's stockholders:
(i) increase the number of shares of Common Stock issuable under the Plan,
except for permissible adjustments in the event of certain changes in the
Corporation's capitalization, (ii) alter the purchase price formula so as to
reduce the purchase price payable for the shares of Common Stock purchasable
under the Plan or (iii) modify eligibility requirements for participation in the
Plan.

XI. GENERAL PROVISIONS

     A. Nothing in the Plan shall confer upon the Participant any right to
continue in the employ of the Corporation or any Corporate Affiliate for any
period of specific duration or interfere with or otherwise restrict in any way
the rights of the Corporation (or any Corporate Affiliate employing such person)
or of the Participant, which rights are hereby expressly reserved by each, to
terminate such person's employment at any time for any reason, with or without
cause.

     B. All costs and expenses incurred in the administration of the Plan shall
be paid by the Corporation; however, each Plan Participant shall bear all costs
and expenses incurred by such individual in the sale or other disposition of any
shares purchased under the Plan.

     C. The provisions of the Plan shall be governed by the laws of the State of
Colorado without regard to that State's conflict-of-laws rules.

     The following definitions shall be in effect under the Plan:

     A. Board shall mean the Corporation's Board of Directors.

     B. Cash Earnings shall mean the (i) base salary payable to a Participant by
one or more Participating Corporations during such individual's period of
participation in one or more offering periods under the Plan plus (ii) all
overtime payments, bonuses, commissions, current profit-sharing distributions
and other incentive-type payments. Such Cash Earnings shall be calculated before
deduction of (A) any income or employment tax withholdings or (B) any pre-tax
contributions made by the Participant to any Code Section 401(k) salary deferral

                                  POWERS/TERM

                                 CAPITAL STOCK

     A. Classes of Stock. The Corporation is authorized to issue two classes of
stock to be designated, respectively, "Common Stock" and "Preferred Stock." The
total number of shares which the Corporation is authorized to issue is two
hundred million (200,000,000) shares. one hundred seventy-five million
<PAGE>   374

(175,000,000) shares, par value $0.001 per share, shall be Common Stock and
twenty-five million (25,000,000) shares, par value $0.001 per share, shall be
Preferred Stock. The consideration for the issuance of the shares shall be paid
to or received by the Corporation in full before their issuance and shall not be
less than the par value per share. The number of authorized shares of Common
Stock may be increased or decreased (but not below the number of shares there of
then outstanding) by the affirmative vote of the holders of a majority of the
stock of the Corporation entitled to vote, irrespective of the provisions of
Section 242(b)(2) of the General Corporation Law of Delaware.

     B. Common Stock.

          (1) General. All shares of Common Stock will be identical and will
     entitle the holders thereof to the same rights, powers and privileges. The
     rights, powers and privileges of the holders of the Common Stock are
     subject to and qualified by the rights of holders of any then outstanding
     Preferred Stock.

          (2) Dividends. Dividends may be declared and paid on the Common Stock
     from funds lawfully available therefor as and when determined by the Board
     of Directors and subject to any preferential dividend rights of any then
     outstanding Preferred Stock.

          (3) Dissolution, Liquidation or Winding Up. In the event of any
     dissolution, liquidation or winding up of the affairs of the Corporation,
     whether voluntary or involuntary, each issued and outstanding share of
     Common Stock shall entitle the holder thereof to receive an equal portion
     of the net assets of the Corporation available for distribution to the
     holders of Common Stock, subject to any preferential rights of any then
     outstanding Preferred Stock.

          (4) Voting Rights. Except as otherwise required by law or this Amended
     and Restated Certificate of Incorporation, each holder of Common Stock
     shall have one vote in respect of each share of stock held of record by
     such holder on the books of the Corporation for the election of directors
     and on all matters submitted to a vote of stockholders of the Corporation.
     Except as otherwise required by law or provided herein, holders of
     Preferred Stock shall vote together with holders of Common Stock as a
     single class, subject to any special or preferential voting rights of any
     then outstanding Preferred Stock. There shall be no cumulative voting.

          (5) Redemption. The Common Stock is not redeemable.

     C. Preferred Stock. The Board of Directors is authorized, subject to
limitations prescribed by law, by the rules of a national securities exchange,
if applicable, and by the provisions of this ARTICLE IV, to provide for the
issuance of the shares of Preferred Stock in series, and by filing a certificate
pursuant to the applicable law of the State of Delaware, to establish from time
to time the number of shares to be included in each such series, and to fix the
designation, powers, preferences, and rights of the shares of each such series
and the qualifications, limitations or restrictions thereof.

     The authority of the Board with respect to each series shall include, but
not be limited to, determination of the following:

          (1) The number of shares constituting that series and the distinctive
     designation of that series;

          (2) The dividend rate on the shares of that series, whether dividends
     shall be cumulative, and, if so, from which date or dates, and the relative
     rights of priority, if any, of payment of dividends on shares of that
     series;

          (3) Whether that series shall have voting rights, in addition to the
     voting rights provided by law, and, if so, the terms of such voting rights;

          (4) Whether that series shall have conversion privileges, and, if so,
     the terms and conditions of such conversion, including provision for
     adjustment of the conversion rate in such events as the Board of Directors
     shall determine;

                                       L-2
<PAGE>   375

          (5) Whether or not the shares of that series shall be redeemable, and,
     if so, the terms and conditions of such redemption, including the date or
     dates upon or after which they shall be redeemable, and the amount per
     share payable in case of redemption, which amount may vary under different
     conditions and at different redemption dates;

          (6) Whether that series shall have a sinking fund for the redemption
     or purchase of shares of that series, and, if so, the terms and amount of
     such sinking fund;

          (7) The rights of the shares of that series in the event of voluntary
     or involuntary liquidation, dissolution or winding up of the Corporation,
     and the relative rights or priority, if any, of payment of shares of that
     series; and

          (8) Any other relative rights, preferences and limitations of that
     series.

     Dividends on outstanding shares of Preferred Stock shall be paid or
declared and set apart for payment before any dividends shall be paid or
declared and set apart for payment on the Common Stock with respect to the same
dividend period.

     If upon any voluntary or involuntary liquidation, dissolution or winding up
of the Corporation, the assets available for distribution to holders of shares
of Preferred Stock of all series shall be insufficient to pay such holders the
full preferential amount to which they are entitled, then such assets shall be
distributed ratably among the shares of all series of Preferred Stock in
accordance with the respective preferential amounts (including unpaid cumulative
dividends, if any) payable with respect thereto.

     D. Preemptive Rights. No holder of any of the shares of any class or series
of stock or of options, warrants or other rights to purchase shares of any class
or series of stock or of other securities of the Corporation shall have any
preemptive right to purchase or subscribe for any unissued stock of any class or
series, or any unissued bonds, certificates of indebtedness, debentures or other
securities convertible into or exchangeable for stock of any class or series or
carrying any right to purchase stock of any class or series; but any such
unissued stock, bonds, certificates or indebtedness, debentures or other
securities convertible into or exchangeable for stock or carrying any right to
purchase stock may be issued pursuant to resolution of the Board of Directors of
the Corporation to such persons, firms, corporations or associations, whether or
not holders thereof, and upon such terms as may be deemed advisable by the Board
of Directors in the exercise of its sole discretion.

                                   ARTICLE V

                                   DIRECTORS

     A. Number. The number of directors of the Corporation shall be such number,
not less than five (5) nor more than fifteen (15) (exclusive of directors, if
any, to be elected by holders of preferred stock of the Corporation, voting
separately as a class), as shall be set forth from time to time in the bylaws.
Vacancies in the Board of Directors of the Corporation, however caused, and
newly created directorships shall be filled by a vote of a majority of the
directors then in office, whether or not a quorum, and any director so chosen
shall hold office for a term expiring at the annual meeting of stockholders at
which the term of the class to which the director has been chosen expires and
when the director's successor is elected and qualified.

     B. Removal of Directors. Notwithstanding any other provisions of this
Certificate or the bylaws of the Corporation, any director or the entire Board
of Directors of the Corporation may be removed, at any time, but only for cause
and only by the affirmative vote of the holders of not less than a majority of
the outstanding shares of capital stock of the Corporation entitled to vote
generally in the election of directors (considered for this purpose as one
class) cast at a meeting of the stockholders called for that purpose.
Notwithstanding the foregoing, whenever the holders of any one or more series of
preferred stock of the Corporation shall have the right, voting separately as a
class, to elect one or more directors of the

                                       L-3
<PAGE>   376

Corporation, the preceding provisions of this ARTICLE V shall not apply with
respect to the director or directors elected by such holders of preferred stock.

                                   ARTICLE VI

                              STOCKHOLDER MEETINGS

     Meetings of stockholders may be held within or without the State of
Delaware, as the Bylaws may provide. The books of the Corporation may be
kept(subject to any provision contained in the statutes) outside the State of
Delaware at such place or places as may be designated from time to time by the
Board of Directors or in the Bylaws of the Corporation. The stockholders of the
Corporation may not take any action by written consent in lieu of a meeting.

                                  ARTICLE VII

                       LIMITATION OF DIRECTORS' LIABILITY

     Except to the extent that the General Corporation Law of Delaware prohibits
the elimination or limitation of liability of directors for breaches of
fiduciary duty, no director of the Corporation shall be personally liable to the
Corporation or its stockholders for monetary damages for any breach of fiduciary
duty as a director, notwithstanding any provision of law imposing such
liability. If the General Corporation Law is amended after approval by the
stockholders of this ARTICLE VII to authorize corporate action further
eliminating or limiting the personal liability of directors, then the liability
of a director of the Corporation shall be eliminated or limited to the fullest
extent permitted by the General Corporation Law of the State of Delaware, as so
amended. No amendment to or repeal of this provision shall apply to or have any
effect on the liability or alleged liability of any director of the Corporation
for or with respect to any acts or omissions of such director occurring prior to
such amendment.

                                  ARTICLE VIII

                                INDEMNIFICATION

     The Corporation may, to the fullest extent permitted by Section 145 of the
General Corporation Law of Delaware, as amended from time to time, indemnify
each person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative, by reason of the fact that he is or
was, or has agreed to become, a director or officer of the Corporation, or is or
was serving, or has agreed to serve, at the request of the Corporation, as a
director, officer or trustee of, or in a similar capacity with, another
corporation, partnership, joint venture, trust or other enterprise (including
any employee benefit plan) (all such persons being referred to hereafter as an
"Indemnitee"), or by reason of any action alleged to have been taken or omitted
in such capacity, against all expenses (including attorneys' fees), judgments,
fines and amounts paid in settlement actually and reasonably incurred by him or
on his behalf in connection with such action, suit or proceeding and any appeal
therefrom.

     Indemnification may include payment by the Corporation of expenses in
defending an action or proceeding in advance of the final disposition of such
action or proceeding upon receipt of an undertaking by the Indemnitee to repay
such payment if it is ultimately determined that such person is not entitled to
indemnification under this ARTICLE VIII, which undertaking may be accepted
without reference to the financial ability of such person to make such
repayment.

     The Corporation shall not indemnify any such person seeking indemnification
in connection with a proceeding (or part thereof) initiated by such person
unless the initiation thereof was approved by the Board of Directors of the
Corporation.

     The indemnification rights provided in this ARTICLE VIII (i) shall not be
deemed exclusive of any other rights to which Indemnitees may be entitled under
any law, agreement or vote of stockholders or
                                       L-4
<PAGE>   377

disinterested directors or otherwise, and (ii) shall inure to the benefit of the
heirs, executors and administrators of such persons. The Corporation may, to the
extent authorized from time to time by its Board of Directors, grant
indemnification rights to other employees or agents of the Corporation or other
persons serving the Corporation and such rights may be equivalent to, or greater
or less than, those set forth in this ARTICLE VIII.

                                   ARTICLE IX

                              AMENDMENT OF BYLAWS

     In furtherance of and not in limitation of powers conferred by statute, the
Board of Directors of the Corporation is expressly authorized to adopt, repeal,
alter, amend and rescind the bylaws of the Corporation by vote of a majority of
the Board of Directors. In addition, the bylaws may be amended by the
affirmative vote of the holders of at least two-thirds of the outstanding shares
of voting stock of the Corporation entitled to vote at an election of directors.

                                   ARTICLE X

                            AMENDMENT OF CERTIFICATE

     The Corporation reserves the right to amend, alter, change or repeal any
provision contained in this Amended and Restated Certificate of Incorporation,
in the manner now or hereafter prescribed by statute and this Amended and
Restated Certificate of Incorporation, and all rights conferred upon
stockholders herein are granted subject to this reservation. Notwithstanding the
foregoing, the provisions set forth in ARTICLES V, VI, VII, VIII, IX and this
ARTICLE X may not be repealed, altered, amended or rescinded in any respect
unless the same is approved by the affirmative vote of the holders of not less
than two-thirds of the outstanding shares of capital stock of the Corporation
entitled to vote generally in the election of directors (considered for this
purpose as a single class) cast at a meeting of the stockholders called for that
purpose (provided that notice of such proposed repeal, alteration, amendment or
rescission is included in the notice of such meeting)."

     FOURTH: That said amendments were duly adopted in accordance with the
provisions of Section 242 and 245 of the General Corporation Law.

                                  CHAPTER 13.
                               DISSENTERS' RIGHTS

sec.1300.  RIGHTS TO REQUIRE PURCHASE -- "DISSENTING SHARES" AND "DISSENTING
           SHAREHOLDER" DEFINED.

     (a) If the approval of the outstanding shares (Section 152) of a
corporation is required for a reorganization under subdivisions (a) and (b) or
subdivision (e) or (f) of Section 1201, each shareholder of the corporation
entitled to vote on the transaction and each shareholder of a subsidiary
corporation is 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 National Market Systems of the NASDAQ
     Stock Market, and the notice of meeting of shareholders to act upon the
     reorganization summarizes this section and Sections 1301, 1302, 1303 and
     1304; provided, however, that this provision does not apply to any shares
     with respect to which there exists any restriction on transfer imposed by
     the corporation or by any law or regulation; and provided, further, that
     this provision does not apply to any class of shares described in
     subparagraph (A) or (B) if demands for payment are filed with respect to 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 or the reorganization or, (B) if described in subparagraph (A) or
     (B) of paragraph (1) (without regard to the provisos in that paragraph),
     were voted against the reorganization, or which were held of record on the
     effective date of a short-form merger; provided, however, that subparagraph
     (A) rather than subparagraph (B) of this paragraph applies in any case
     where the approval required by Section 1201 is sought by written consent
     rather than at a meeting.

          (3) Which the dissenting shareholder has demanded that the corporation
     purchase at their fair market value, in accordance with Section 1301.

          (4) Which the dissenting shareholder has submitted for endorsement, in
     accordance with Section 1302.

     (c) As used in this chapter, "dissenting shareholder" means the
recordholder of dissenting shares and includes a transferee of record.

sec.1301.  DEMAND FOR PURCHASE.

     (a) If, in the case of a reorganization, any shareholders of a corporation
have a right under Section 1300, subject to compliance with paragraphs (3) and
(4) of subdivision (b) thereof, to require the corporation to purchase their
shares for cash, such corporation shall mail to each such shareholder a notice
of the approval of the reorganization by its outstanding shares (Section 152)
within 10 days after the date of such approval, accompanied by a copy of Section
1300, 1302, 1303, 1304 and this section, a statement
<PAGE>   380

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 subdivision (b)
of Section 1300, unless they lose their status as dissenting shares under
Section 1309.

     (b) Any shareholder who has a right to require the corporation to purchase
the shareholder's shares for cash under Section 1300, subject to compliance with
paragraphs (3) and (4) of subdivision (b) thereof, and who desires the
corporation to purchase such shares shall make written demand upon the
corporation for the purchase of such shares and payment to the shareholder in
cash of their fair market value. The demand is not effective for any purpose
unless it is received by the corporation or any transfer agent thereof (1) in
the case of shares described in clause (i) or (ii) of paragraph (1) of
subdivision (b) of Section 1300 (without regard to the provisos in that
paragraph), not later than the date of the shareholders' meeting to vote upon
the reorganization, or (2) in any other case within 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 of short-form merger. The statement of fair market value
constitutes an offer by the shareholder to sell the shares at such price.

sec.1302.  ENDORSEMENT OF SHARES.

     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.

sec.1303.  AGREED PRICE -- TIME FOR PAYMENT.

     (a) If the corporation and the shareholder agree that the shares are
dissenting shares and agree upon the price of the shares, the dissenting
shareholder is entitled to the agreed price with interest thereon at the legal
rate on judgments from the date of the agreement. Any agreements fixing the fair
market value of any dissenting shares as between the corporation and the holders
thereof shall be filed with the secretary of the corporation.

     (b) Subject to the provisions of Section 1306; payment of the fair market
value of dissenting shares shall be made within 30 days after the amount thereof
has been agreed or within 30 days after any statutory or contractual conditions
to the reorganization are satisfied, whichever is later, and in the case of
certificated securities, subject to surrender of the certificates therefor,
unless provided otherwise by agreement.

sec.1304.  DISSENTERS ACTIONS TO ENFORCE PAYMENT.

     (a) If the corporation denies that the shares are dissenting shares, or the
corporation and the shareholder fail to agree upon the fair market 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
                                       N-2
<PAGE>   381

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 plaintiff, 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.

sec.1305.  APPRAISERS REPORT -- PAYMENT  --  COSTS.

     (a) If the court appoints an appraiser or appraisers, they shall proceed
forthwith to determine the fair market value per share. Within the time fixed by
the court, the appraisers, or a majority of them, shall make and file a report
in the office of the clerk of the court. Thereupon, on the motion of any party,
the report shall be submitted to the court and considered on such evidence as
the court considers relevant. If the court finds the report reasonable, the
court may confirm it.

     (b) If a majority of the appraisers appointed fail to make and file a
report within 10 days from the date of their appointment or within such further
time as may be allowed by the court or the report is not confirmed by the court,
the court shall determine the fair market value of the dissenting shares.

     (c) Subject to the provisions of Section 1306, judgment shall be rendered
against the corporation for payment of an amount equal to the fair market value
of each dissenting share multiplied by the number of dissenting shares which any
dissenting shareholder who is a party, or who has intervened, is entitled to
require the corporation to purchase, with interest thereon at the legal rate
from the date on which judgment was entered.

     (d) Any such judgment shall be payable forthwith with respect to
uncertificated securities and, with respect to certificated securities, only
upon the endorsement and delivery to the corporation of the certificates for the
shares described in the judgment. Any party may appeal from the judgment.

     (e) The costs of the action, including reasonable compensation to the
appraisers to be fixed by the court, shall be assessed or apportioned as the
court considers equitable, but, if the appraisal exceeds the price offered by
the corporation, the corporation shall pay the costs (including in the
discretion of the court attorneys' fees, fees of expert witnesses and interest
at the legal rate on judgments from the date of compliance with Sections 1300,
1301 and 1302 if the value awarded by the court for the shares is more than 125
percent of the price offered by the corporation under subdivision (a) of Section
1301).

sec.1306.  DISSENTING SHAREHOLDERS STATUS AS CREDITORS.

     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.

sec.1307.  DIVIDENDS PAID AS CREDIT AGAINST PAYMENT.

     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.

                                       N-3
<PAGE>   382

sec.1308.  CONTINUING RIGHTS AND PRIVILEGES OF DISSENTING SHAREHOLDERS.

     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.

sec.1309.  TERMINATING OF DISSENTING SHAREHOLDER STATUS.

     Dissenting shares lose their status as dissenting shares and the holders
thereof cease to be dissenting shareholders and cease to be entitled to require
the corporation to purchase their shares upon the happening of any of the
following:

     (a) The corporation abandons the reorganization. Upon abandonment of the
reorganization, the corporation shall pay on demand to any dissenting
shareholder who has initiated proceedings in good faith under this chapter all
necessary expenses incurred in such proceedings and reasonable attorneys' fees.

     (b) The shares are transferred prior to their submission for endorsement in
accordance with Section 1302 or are surrendered for conversion into shares of
another class in accordance with the articles.

     (c) The dissenting shareholder and the corporation do not agree upon the
status of the shares as dissenting shares or upon the purchase price of the
shares, and neither files a complaint or intervenes in a pending action as
provided in Section 1304, within six months after the date on which notice of
the approval by the outstanding shares or notice pursuant to subdivision (i) of
Section 1110 was mailed to the shareholder.

     (d) The dissenting shareholder, with the consent of the corporation,
withdraws the shareholder's demand for purchase of the dissenting shares.

sec.1310.  SUSPENSION OF PROCEEDINGS FOR PAYMENT PENDING LITIGATION.

     If litigation is instituted to test the sufficiency or regularity of the
votes of the shareholders in authorizing a reorganization, any proceeding under
Sections 1304 and 1305 shall be suspended until final determination of such
litigation.

sec.1311.  EXEMPT SHARES.

     This chapter, EXCEPT SECTION 1312, does not apply to classes of shares
whose terms and provisions specifically set forth the amount to be paid in
respect to such shares in the event of a reorganization or merger.

sec.1312.  ATTACKING VALIDITY OF REORGANIZATION OR MERGER.

     (a) No shareholder of a corporation who has a right under this chapter to
demand payment of cash for the shares held by the shareholder shall have any
right at law or in equity to attack the validity of the reorganization or
short-form merger, or to have the reorganization or short-form merger set aside
or rescinded, except in an action to test whether the number of shares required
to authorize or approve the reorganization have been legally voted in favor
thereof; but any holder of shares of a class whose terms and provisions
specifically set forth the amount to be paid in respect to them in the event of
a reorganization or short-form merger is entitled to payment in accordance with
those terms and provisions or, if the principal terms of the reorganization are
approved pursuant to subdivision (b) of Section 1202, is entitled to payment in
accordance with the terms and provisions of the approved reorganization.

     (b) If one of the parties to a reorganization or short-form merger is
directly or indirectly controlled by, or under common control with, another
party to the reorganization or short-form merger, subdivision (a) shall not
apply to any shareholder of such party who has not demanded payment of cash for
such shareholder's shares pursuant to this chapter; but if the shareholder
institutes any action to attack the validity of the reorganization or short-form
merger or to have the reorganization or short-form merger
                                       N-4
<PAGE>   383

set aside or rescinded, the shareholder shall not thereafter have any right to
demand payment of cash for the shareholder's shares pursuant to this chapter.
The court in any action attacking the validity of the reorganization or
short-form merger or to have the reorganization or short-form merger set aside
or rescinded shall not restrain or enjoin the consummation of the transaction
except upon 10 days, prior notice to the corporation and upon a determination by
the court that clearly no other remedy will adequately protect the complaining
shareholder or the class of shareholders of which such shareholder is a member.

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

                     INFORMATION NOT REQUIRED IN PROSPECTUS

ITEM 20. INDEMNIFICATION OF OFFICERS AND DIRECTORS

     The Registrant's certificate of incorporation in effect as of the date
hereof (the "Certificate") provides that, except to the extent prohibited by the
Delaware General Corporation Law, as amended (the "DGCL"), the registrant's
directors shall not be personally liable to the registrant or its stockholders
for monetary damages for any breach of fiduciary duty as directors of the
registrant. Under the DGCL, the directors have a fiduciary duty to the
registrant which is not eliminated by this provision of the Certificate and, in
appropriate circumstances, equitable remedies such as injunctive or other forms
of non-monetary relief will remain available. In addition, each director will
continue to be subject to liability under the DGCL for breach of the director's
duty of loyalty to the registrant, for acts or omissions which are found by a
court of competent jurisdiction to be not in good faith or involving intentional
misconduct, for knowing violations of law, for actions leading to improper
personal benefit to the director, and for payment of dividends or approval of
stock repurchases or redemptions that are prohibited by DGCL. This provision
also does not affect the directors' responsibilities under any other laws, such
as the Federal securities laws or state or Federal environmental laws.

     Section 145 of the DGCL empowers a corporation to indemnify its directors
and officers and to purchase insurance with respect to liability arising out of
their capacity or status as directors and officers, provided that this provision
shall not eliminate or limit the liability of a director: (i) for any breach of
the director's duty of loyalty to the corporation or its stockholders, (ii) for
acts or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (iii) arising under Section 174 of the DGCL, or (iv)
for any transaction form which the director derived an improper personal
benefit. The DGCL provides further that the indemnification permitted thereunder
shall not be deemed exclusive of any other rights to which the directors and
officers may be entitled under the corporation's bylaws, any agreement, a vote
of stockholders or otherwise. The Certificate eliminates the personal liability
of directors to the fullest extent permitted by Section 102(b)(7) of the DGCL
and provides that the registrant shall fully indemnify any person who was or is
a party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding (whether civil, criminal, administrative or
investigative) by reason of the fact that such person is or was a director or
officer of the registrant, or is or was serving at the request of the registrant
as a director or officer of another corporation, partnership, joint venture,
trust, employee benefit plan or other enterprise, against expenses (including
attorney's fees), judgments, fines and amounts paid in settlement actually and
reasonably incurred by such person in connection with such action, suit or
proceeding.

     Article VII Section 6 of the registrant's Amended and Restated Bylaws
provides that the registrant shall indemnify its directors and officers to the
fullest extent not prohibited by the Delaware General Corporation Law. The
rights to indemnify thereunder continue as to a person who has ceased to be a
director, officer, employee or agent and inure to the benefit of the heirs,
executors and administrators of the person. In addition, expenses incurred by a
director or officer in defending any civil or criminal action, suite or
proceeding by reason of the fact that he or she is or was a director or officer
of the registrant (or was serving at the registrant's request as a director or
officer of another corporation) shall be paid by the registrant in advance of
the final disposition of such action, suit or proceeding upon receipt of an
undertaking by or on behalf of such director or officer to repay such amount if
it shall ultimately be determined that he or she is not entitled to be
indemnified by the registrant as authorized by the relevant sections of the
Delaware General Corporation Law.

     Caldera has entered into indemnification agreements with each of its
outside directors. Generally, the indemnification agreements attempt to provide
the maximum protection permitted by Delaware law as it may be amended from time
to time. Moreover, the indemnification agreements provide for certain additional
indemnification. Under such additional indemnification provisions, however, an
individual will not receive indemnification for judgments, settlements or
expenses if he or she is found liable to Caldera

                                      II-1
<PAGE>   386

(except to the extent the court determines he or she is fairly and reasonable
entitled to indemnity for expenses), for settlements not approved by Caldera.
The indemnification agreements provide for Caldera to advance to the individual
any and all reasonable expenses (including legal fees and expenses) incurred in
investigating or defending any such action, suit or proceeding. Upon the closing
of the combination, the registrant will assume the indemnification agreements of
Caldera and will enter into similar indemnification agreements with
newly-appointed outside directors.

     Caldera has an insurance policy covering its directors and officers with
respect to certain liabilities, including liabilities arising under the
Securities Act or otherwise. Upon the closing of the combination, the registrant
will assume this insurance policy.

     Schedules not listed above have been omitted because the information

ITEM 22. UNDERTAKINGS

     The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the 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.

     The undersigned registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.

     The undersigned registrant hereby undertakes as follows:

        (1) 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;

        (2) that every prospectus (i) that is filed pursuant to paragraph (1)
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 Securities Act of 1933, 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.

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the foregoing provisions, Delaware Corporation law, the
Underwriting Agreement or otherwise, the registrant has been advised that in the
opinion of the Securities and Exchange Commission such indemnification is
against public policy as expressed in the Act and is, therefor, 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 question has been
settled by controlling precedent, submit to a court of appropriate jurisdiction
the question of whether such indemnification by it is against public policy as
expressed in the Act and will be governed by the final adjudication of such
issue.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
                        ON FINANCIAL STATEMENT SCHEDULE

To Caldera Systems, Inc.:

     We have audited in accordance with auditing standards generally accepted in
the United States, the consolidated financial statements of Caldera Systems,
Inc, the carved-out portion of Caldera, Inc. and their subsidiary included in
this registration statement and have issued our report thereon dated January 10,
2000. Our audit was made for the purpose of forming an opinion on the basic
financial statements taken as a whole. Schedule II -- Valuation and Qualifying
Accounts is the responsibility of the Company's management and is presented for
purposes of complying with the Securities and Exchange Commission's rules and is
not part of the basic financial statements. This schedule has been subjected to
the auditing procedures applied in the audit of the basic financial statements
and, in our opinion, fairly states in all material respects the financial data
required to be set forth therein in relation to the basic financial statements
taken as a whole.
