preceding sentence and options to purchase 1,333,950 shares of the common stock
of Lineo granted to employees and members of the Board of Directors of Lineo
pursuant to Lineo's Stock Option Plan, Lineo has not issued any warrants,

expenses incurred on behalf of Lineo, and (iii) for other standard employee
benefits made generally available to all employees (including stock option

of such persons has any direct or indirect ownership interest in any firm or
corporation with which Lineo is affiliated or with which Lineo has a business
relationship, or any firm or corporation that competes with Lineo, except that
employees, stockholders, officers or directors of Lineo and members of their
immediate families may own stock in publicly-traded companies that may compete
with Lineo. To the best of Lineo's, no officer, director or stockholder or any
member of their immediate families is, directly or indirectly, interested in any

or any of its securities that may subsequently be issued.

2.9   PERMITS.

      Lineo has all franchises, permits, licenses, and any similar authority
necessary for the conduct of its business as now being conducted by it, the lack
of which could materially and adversely affect the business, properties,
prospects or financial condition of Lineo, and believes it can obtain, without
undue burden or expense, any similar authority for the conduct of its business
as presently planned to be conducted. Lineo is not in default in any material
respect under any of such franchises, permits, licenses or other similar
authority.

2.10  LITIGATION.

      There is no action, suit, proceeding or investigation pending or, to the
best of Lineo's knowledge, currently threatened against Lineo that questions the
validity of this Agreement, or the right of Lineo to enter into this Agreement,
or to consummate the transactions contemplated hereby, or that might result,

assets, business, properties, prospects, or financial condition of Lineo, or in
any material change in the current equity ownership of Lineo.

2.11  RETURNS AND COMPLAINTS.

2.13  OFFERING.

      Subject, in part, to the truth and accuracy of Caldera Systems's
representations set forth in this Agreement, the offer, sale and issuance of the

acting on its behalf will take any action hereafter that would cause the loss of

obligations not past due to carriers, warehousemen, laborers, materialmen and
the like, (iv) for liens in respect of pledges or deposits under workers'
compensation laws or similar legislation or (v) for minor defects in title, none
of which, individually or in the aggregate, materially interferes with the use
of such property, Lineo has good and marketable title to its property and assets
free and clear of all mortgages, liens, claims and encumbrances. With respect to
the property and assets it leases, Lineo is in compliance

with such leases and, to the best of its knowledge, holds a valid leasehold
interest free of any liens, claims or encumbrances, subject to clauses (i)-(v)
above.

2.15  FINANCIAL STATEMENTS.

      Lineo has made available to Caldera Systems its unaudited trial balance
sheet (which includes assets and liabilities, ending balances, revenues and
expenses, and the balance of stockholders' equity) at October 31, 1999 for the
fiscal year then ended (the "Lineo Financial Statements"). The Lineo Financial
Statements have been prepared in accordance with generally accepted accounting
principles applied on a consistent basis throughout the periods indicated. The
Lineo Financial Statements fairly present the financial condition and operating
results of Lineo as of the dates, and for the periods, indicated therein. Except
as set forth in the Lineo Financial Statements, Lineo has no material
liabilities, contingent or otherwise, other than (i) liabilities incurred in the
ordinary course of business subsequent to October 31, 1999 and (ii) obligations
under contracts and commitments incurred in the ordinary course of business and
not required under generally accepted accounting principles to be reflected in
the Lineo Financial Statements, which in both cases, individually or in the
aggregate, are not material to the financial condition or operating results of
Lineo. Except as disclosed in the Lineo Financial Statements, Lineo is not a
guarantor or indemnitor of any indebtedness of any other person, firm or
corporation. Lineo maintains and will continue to maintain a standard system of
accounting established and administered in accordance with generally accepted
accounting principles.

            demand is pending or, to the best of Lineo's or its Subsidiaries'
            knowledge, and the knowledge of the directors and officers (and
            employees with responsibility for Intellectual Property matters) of
            Lineo and its Subsidiaries, is threatened which challenges the
            legality, validity, enforceability, use, or ownership of the IP
            item; and

                  (D) Lineo has never agreed to indemnify any Person for or
            against any interference, infringement, misappropriation, or other
            conflict with respect to the IP item.

            (iii) The Lineo IP Schedule will identify each item of Intellectual
      Property that any third party owns and licenses to Lineo, excluding
      licenses to commercially available software products (e.g., Windows,

event has occurred which with notice or lapse of time would constitute a breach
or default or permit termination, modification, or acceleration thereunder;

                  no party  to the  agreement  has  repudiated  any  provision
thereof;

                  the  license is not subject to any  outstanding  injunction,
judgment, order, decree, ruling, or charge; and

<PAGE>   7

complaint, claim, or demand is pending or is threatened which challenges the
legality, validity, or enforceability of the license or agreement.

            (iv) To the best of Lineo's knowledge and to the knowledge of the
      directors and officers (and employees with responsibility for Intellectual
      Property matters) of Lineo, Lineo will not infringe, misappropriate, or
