                              STOCKHOLDER AGREEMENT

         THIS STOCKHOLDER AGREEMENT (this "AGREEMENT") is made and entered into
as of _______________ 2000 by and between Lineo, Inc., a Delaware corporation
(the "COMPANY"), Caldera Systems, Inc., a Delaware corporation ("CALDERA") The
Canopy Group, a Utah corporation ("CANOPY"), Bryan Sparks, an individual
("SPARKS"), Dry Canyon Holding Company, LLC, a Utah limited liability company
("DRY CANYON"), and Metrowerks Holdings, Inc., a Delaware corporation
("METROWERKS"). Caldera, Canopy, Sparks and Dry Canyon are sometimes
collectively referred to herein as the "STOCKHOLDERS," and each individually as
a "STOCKHOLDER."

                                    RECITALS

         A In connection with the issuance of that certain Common Stock Warrant
of even date herewith (the "Warrant") pursuant to the terms of the Warrant
Purchase Agreement of even date herewith (the "Warrant Purchase Agreement") by
and between the Company and Metrowerks, and that certain Stock Purchase
Agreement of even date herewith (the "Stock Purchase Agreement") by and among
Metrowerks, Canopy, and Caldera, the parties wish to make certain arrangements
in connection with the sale of all of the shares of common stock of the Company
currently owned by Sparks, Dry Canyon, Caldera and Canopy (collectively, the
"STOCK").

         B. The Company and Metrowerks also wish to enter into an arrangement
whereby Metrowerks has the ability to negotiate with the Company with respect to
a Major Transaction, as defined below.

         NOW, THEREFORE, in consideration of the mutual promises and covenants
set forth herein, the parties agree as follows:

                                    SECTION 1

                           RIGHT OF FIRST OPPORTUNITY

         1.1 GENERAL. Subject to the terms and conditions specified in this
Section 1, each Stockholder hereby grants to Metrowerks a right of first
opportunity with respect to future sales by any Stockholder of such
Stockholder's shares of the Stock.

         1.2 STOCKHOLDER OFFERING. Each time a Stockholder proposes to offer for
sale any of the Stock, such Stockholder shall first make an offering of such
Stock to Metrowerks in accordance with the provisions of this Section 1;
thereafter Metrowerks may exercise its right of first opportunity in accordance
with the procedures set forth below.

         1.3 NOTICE OF SALES BY STOCKHOLDER. If any Stockholder proposes to sell
or transfer any Stock, then such Stockholder shall promptly give written notice
(the "NOTICE") to Metrowerks. The Notice shall describe in reasonable detail the
proposed sale or transfer including, without limitation, the number of shares to
be sold or transferred, the nature of such

                                       1

<PAGE>

sale or transfer, the consideration to be paid, and the name and address of each
prospective purchaser or transferee.

         1.4 METROWERKS' RIGHT TO PURCHASE. Within forty-five (45) calendar days
after receiving the Notice, Metrowerks may elect to purchase or obtain, at the
price and on the terms specified in the Notice, all of the shares proposed to be
sold as described in the Notice; provided, however, that if any Notice is
delivered after the effective date of the Company's first firmly underwritten
public offering of its securities (the "Initial Public Offering"), and such
Notice describes a sale or transfer exclusively on the public market (a "Public
Sale"), Metrowerks must make such election within twenty-four (24) hours of
receipt of the Notice; provided, further, that any such Public Sale must (i) be
a "brokers' transaction" as defined in Rule 144(g) of the Securities Act of
1933, as amended (the "Securities Act"), and (ii) not result in the transfer of
greater than 15% of such Stockholder's Stock to any single entity or group of
affiliated entities; and copies of all filings with the Securities Exchange
Commission in connection with any Public Sale must be furnished to Metrowerks in
advance of any such sale. Notwithstanding anything herein to the contrary, in
the event of a Public Sale by any Stockholder in connection with the Company's
registration of securities pursuant to Section 5.2 of that certain Investor
Rights Agreement dated as of February 17, 2000, by and among the Company and the
parties thereto, as amended (the "Investor Rights Agreement", and such sale, the
"Piggyback Sale"), Metrowerks must make such election within 20 days after
receipt of the written notice from the Company provided for in Section
5.2(a)(ii) of the Investor Right Agreement.

         1.5 UNPURCHASED SHARES. If all of the shares of Stock referred to in
the Notice are not elected to be purchased as provided in Section 1.4, the
Stockholder may, in the case of a sale other than a Public Sale or a Piggyback
Sale, during the 60-day period following the expiration of the period provided
in Section 1.4 offer such unpurchased Stock to any person or persons at a price
not less than, and upon terms no more favorable to the offeree than those
specified in the Notice. If either (i) in the case of a sale other than a Public
Sale or a Piggyback Sale, the Stockholder does not enter into an agreement for
the sale of the Stock within such period, or if such agreement is not
consummated within 30 days of the execution thereof, (ii) in the case of a
Public Sale, if the sale is not consummated within the 7-day period following
the expiration of the period provided in Section 1.4, or (iii) in the case of a
Piggyback Sale, if the sale is not consummated within the 7-day period following
the effective date of the registration statement filed by the Company pursuant
to Section 5.2 of the Investor Rights Agreement, the right provided hereunder
shall be deemed to be revived and such Stock shall not be offered unless first
reoffered to Metrowerks in accordance herewith. Notwithstanding anything herein
to the contrary, the amount of time in which such Stockholder must consummate a
sale of Stock before Metrowerks' rights hereunder are revived will be tolled to
allow such Stockholder to comply with any federal or state securities,
antitrust, or other similar laws, rules or regulations; provided, however, that
no such tolling will apply to the extent that any delay is the result of or is
caused by the actions of the Stockholder or the third party to whom such
Stockholder intends to sell the Stock.

         1.6 VOID TRANSFERS. Notwithstanding the foregoing, any attempt by a
Stockholder to transfer Stock in violation of Section 1 hereof, shall be void
and the Company agrees it will not effect such a void transfer nor will it treat
any alleged transferee as the holder of such shares without the written consent
of Metrowerks.

                                    SECTION 2

                          CHANGE IN CONTROL TRANSACTION

         2.1 The Company shall not enter into an agreement with any third party
providing for (i) any transaction, including, without limitation, a merger,
consolidation, or sale of securities (whether outstanding prior to the
transaction or issued in such transaction), pursuant to which the stockholders
of the Company immediately prior to the effective date of such transaction(s)
would have beneficial ownership of less than fifty percent (50%) of the total
combined voting power for the election of directors of the surviving corporation
immediately following such transaction, or (ii) the sale of all or substantially
all of the assets of the Company ((i) and (ii), each a "Major Transaction"),
other than as expressly provided in this Section 2.

         2.2 In the event that the Board of Directors of the Company desires to
make or accept a bona fide offer to be acquired (a "Proposal") by a third party
(the "Acquiror") by means of a Major Transaction, the Company shall provide a
written offer to Metrowerks (the "Major Transaction Notice"), either (i) in the
event that the Board of Directors receives a Proposal (a "Third Party
Proposal"), within two (2) business days of the decision by the Board of
Directors to either (A) accept, subject to the Company's obligations to
Metrowerks as set forth in Section 2.4 below, such Third Party Proposal, or (B)
begin an auction process (a "Company Auction") for the sale of the Company, or
(ii) where the Board of Directors has decided to initiate a Proposal (a "Company
Proposal"), subject to the provisions of Section 2.3 below, at any time prior to
such delivery to any third party, whereby, (A) in the case of a Company
Proposal, subject to the provisions of Section 2.3 below, Metrowerks may acquire
the same interest in the Company or its assets, as the case may be, on terms and
conditions, including price, not less favorable to Metrowerks than those
contained in the Company Proposal, or (B) in the case of a Third Party Proposal
or a Company Auction, Metrowerks shall have the right to submit an offer to the
Company, as set forth in Section 2.4 below. The Major Transaction Notice shall
include the following information: (i) the identity of the Acquiror (if known)
and (ii) the specific terms of the Third Party Proposal, the Company Proposal,
or the Company Auction, as the case may be. Further, the Company shall provide a
true and complete copy of the Third Party Proposal or the Company Proposal, as
the case may be, if in writing, or a written summary of the material terms
thereof if such Third Party Proposal or Company Proposal, as the case may be, is
not in writing, as well as access to (and copies of, if requested) all documents
containing nonpublic information of the Company that are or have been supplied
to the Acquiror.

         2.3 In the case of a Company Proposal, Metrowerks shall have twenty
(20) business days (which time period may be extended by mutual written
agreement) following its receipt of the Major Transaction Notice in which to
provide written notice to the Company of its willingness to enter into a Major
Transaction on such terms and conditions, including price, as set forth in the
Major Transaction Notice (the "Acceptance"); provided, however, that at any time
prior to the submission of the Company Proposal to Metrowerks and/or acceptance
by Metrowerks of such Company Proposal, the Board of Directors of the Company
may, in its sole discretion, determine that it is in the best interest of the
Company and the Company's stockholders to initiate a Company Auction for the
purchase and sale of the Company, and that failure to do so would constitute a
breach of the fiduciary duties of the Board of Directors, in which case, the
Company shall have the right to submit such Company Proposal to, and/or solicit

                                       3
<PAGE>

Third Party Proposals from, third parties in addition to Metrowerks.
Notwithstanding anything to the contrary in this Section 2.3, in no event shall
any third party receive a Company Proposal or be solicited for a Third Party
Proposal at any time prior to Metrowerks' receipt of the Major Transaction
Notice pursuant to Section 2.2 above. Metrowerks shall continue to have the
right to receive notice of any Third Party Proposals received as a result of a
Company Auction, and to participate in the Company Auction, as set forth in
Section 2.4 below.

         2.4 In the case of a Third Party Proposal or a Company Auction,
Metrowerks shall have twenty (20) business days (which time period may be
extended by mutual written agreement) following its receipt of the Major
Transaction Notice in which to provide written notice to the Company (the
"Metrowerks Offer") of the price, terms and conditions upon which Metrowerks
would be willing to acquire the Company by means of a Major Transaction. The
Company shall then have five (5) business days (which time period may be
extended by mutual written agreement) following its receipt of the Metrowerks
Offer in which to provide either (i) written notice to Metrowerks of its
acceptance (the "Notice of Acceptance") or rejection (the "Notice of Rejection")
of the Metrowerks Offer, or (ii) a true and complete copy of any amended Third
Party Proposal (the "Acquiror Counter-Offer"). Metrowerks shall have five (5)
business days following its receipt of any Acquiror Counter-Offer or the Notice
of Rejection in which to deliver to the Company a written amendment to the
Metrowerks Offer (such amendment shall be considered a Metrowerks Offer for all
purposes under this Section 2). Notwithstanding anything herein to the contrary,
the Company shall not be obligated to accept any Metrowerks Offer; provided,
however, that the Company cannot enter into any Major Transaction pursuant to a
Third Party Proposal or an Acquiror Counter-Offer on economic terms, including
price, that are less favorable to the Company, when taken as a whole, than the
terms set forth in any Metrowerks Offer.

         2.5      In the event that:

                  (a) Metrowerks does not deliver the Acceptance or the
Metrowerks Offer, as the case may be, to the Company within twenty (20) business
days (or other mutually agreed upon time period, as set forth above), after its
receipt of the Major Transaction Notice;

                  (b) Metrowerks does not deliver a Metrowerks Offer to the
Company within five (5) business days (or other mutually agreed upon time
period, as set forth above), after its receipt of any Acquiror Counter-Offer; or

                                       4
<PAGE>

                  (c) Within sixty (60) days (or other mutually agreed upon time
period) following the date of Metrowerks' delivery of the Acceptance or the
Company's delivery of the Notice of Acceptance, Metrowerks and the Company have
not signed a definitive agreement to complete the Major Transaction described in
the Major Transaction Notice or the Metrowerks Offer, as the case may be
(provided that each of the parties thereto acted in good faith in negotiating
such agreement),

then, (i) in the case of a Company Proposal, within 90 days of the date of
delivery of such Company Proposal, or (ii) in the case of a Third Party
Proposal, the greater of (A) 90 days after the Company's receipt of the Third
Party Proposal, and (B) 30 days after the date of delivery of the last
Metrowerks Offer, the Company may consummate a Major Transaction with the
Acquiror, on economic terms, including price, that are no less favorable to the
Company, when taken as a whole, than the most favorable terms set forth in any
Metrowerks Offer, or if more favorable to the Company, the Major Transaction
Notice. In the event that the Company and the Acquiror do not consummate such
Major Transaction within such 90 or 30 day period, as the case may be, then the
Proposal shall be deemed to lapse and any agreement to consummate a Major
Transaction shall be deemed to be in violation of this Section 2 unless
Metrowerks is once again afforded the right of first refusal provided for in
this Section 2 with respect to such Company Proposal or Third Party Proposal, as
the case may be.

         2.6 The Company agrees to act in good faith in all respects concerning
the carrying out of the intent of this Section 2 and shall use its best efforts
to ensure that its employees, stockholders, directors and other agents abide by
the intent of this Section 2 and do not take any action inconsistent with this
Section 2.

         2.7 FIDUCIARY OBLIGATIONS. Fiduciary Obligations. Notwithstanding any
of the foregoing provisions, nothing contained in this Agreement shall prevent
the Company from taking any action with respect to a potential Major Transaction
which, after consultation with outside counsel, the Board of Directors of the
Company determines is necessary to prevent a breach of its fiduciary duties or
other legal obligations.

                                    SECTION 3

                                EXEMPT TRANSFERS

         3.1 STOCKHOLDERS' RIGHTS. Notwithstanding the foregoing, the rights of
Metrowerks under Section 1 shall not apply to (i) any pledge of Stock made
pursuant to a BONA FIDE loan transaction that creates a mere security interest,
(ii) any transfer to the ancestors, descendants or spouse of Stockholder or to
trusts for the benefit of such persons pursuant to legitimate estate planning
practices; or (iii) any other BONA FIDE gift or donation to a charitable or
religious organization that is an "exempt organization" within the meaning of
Section 501(c)(3) of the Internal Revenue Code of 1986, as amended (a
"Charitable Organization"); provided that (A) Stockholder shall inform
Metrowerks of such pledge, transfer, gift or donation prior to effecting it and
(B) the pledgee, transferee or donee shall furnish Metrowerks with a written
agreement to be bound by and comply with all provisions of this Agreement. Such
transferred Stock shall remain "STOCK" hereunder, and such pledgee, transferee
or donee shall be treated as a "STOCKHOLDER" for purposes of this Agreement.
Notwithstanding anything herein to the contrary,

                                       5

<PAGE>

the rights of Metrowerks under Section 1 shall not apply to any transfer or
series of transfers of up to an aggregate of 750,000 shares of Stock by Sparks
in one or more transactions to any one or more Charitable Organizations.

                                    SECTION 4

                                     LEGEND

         4.1 LEGEND. Each certificate representing shares of Stock now or
hereafter owned by the Stockholders or issued to any person in connection with a
transfer pursuant to Section 3.1 hereof shall be endorsed with the following
legend:

             "THE SALE, PLEDGE, HYPOTHECATION OR TRANSFER OF THE SECURITIES
             REPRESENTED BY THIS CERTIFICATE IS SUBJECT TO THE TERMS AND
             CONDITIONS OF A CERTAIN STOCKHOLDER AGREEMENT BY AND BETWEEN
             THE STOCKHOLDER, THE CORPORATION AND CERTAIN HOLDERS OF STOCK
             OF THE CORPORATION. COPIES OF SUCH AGREEMENT MAY BE OBTAINED
             UPON WRITTEN REQUEST TO THE SECRETARY OF THE CORPORATION."

         4.2 REMOVAL. Each Stockholder agrees that the Company may instruct its
transfer agent to impose transfer restrictions on the shares represented by
certificates bearing the legend referred to in Section 4.1 above to enforce the
provisions of this Agreement and the Company agrees to promptly do so. The
legend shall be removed upon termination of this Agreement.

                                    SECTION 5

                                  MISCELLANEOUS

         5.1 GOVERNING LAW. This Agreement and the legal relations between the
parties arising hereunder shall be governed by and interpreted in accordance
with the laws of the State of Delaware, without regard to conflicts of laws
principles.

         5.2 AMENDMENT. Any provision may be amended and the observance thereof
may be waived (either generally or in a particular instance and either
retroactively or prospectively), only by the written consent of each of the
parties to this Agreement, or their lawful assigns, if applicable; provided,
however, that any amendment which does not adversely effect the rights of a
Stockholder may be approved by the Company, Metrowerks, and the Stockholders who
hold, in the aggregate, a majority of the Stock.

         5.3 ASSIGNMENT OF RIGHTS. Except as otherwise provided herein, the
provisions hereof shall inure to the benefit of, and be binding upon, the
successors, assigns, heirs, executors and administrators of the parties hereto;

with the written consent of the Company and the Stockholder.

         5.4 TERM. Except for Section 1, the provisions of this Agreement shall
terminate upon the closing of a Change in Control Transaction.

         5.5 OWNERSHIP. Each Stockholder represents and warrants that it is the
sole legal and beneficial owner of the shares of Stock subject to this Agreement
and that no other person has any interest (other than a community property
interest) in such shares.

         5.6 NOTICES. All notices required or permitted hereunder shall be in

         5.7 SEVERABILITY. In the event that any provision of this Agreement
becomes or is declared by a court of competent jurisdiction to be illegal,
unenforceable or void, this Agreement shall continue in full force and effect
without said provision; provided that no such severability shall be effective if
it materially changes the economic benefit of this Agreement to any party.

         5.8 TITLES AND SUBTITLES. The titles and subtitles used in this
Agreement are used for convenience only and are not to be considered in
construing or interpreting this Agreement.

         5.9 ATTORNEYS' FEES. In the event that any dispute among the parties to
this Agreement should result in litigation, the prevailing party in such dispute
shall be entitled to recover from the losing party all fees, costs and expenses
of enforcing any right of such prevailing party under or with respect to this
Agreement, including without limitation, such reasonable fees and expenses of
attorneys and accountants, which shall include, without limitation, all fees,
costs and expenses of appeals.

         5.10 DISPUTE RESOLUTION. In the event that after the date hereof, there
is any dispute between any of the Company, Metrowerks and any Stockholder, then
the following procedure shall be followed:

                  (a) Upon the occurrence of such a dispute either the Company,
such Stockholder(s) or Metrowerks may by written notice (the "Initial Notice")
to the other parties call for the consideration of such dispute by the Company
and such Stockholder(s), on the one hand, and the general manager of the
Metrowerks Division of Motorola's Semiconductor Products Sector ("SPS"), or such
person's successor (such persons, the "Transaction Committee"). The Transaction
Committee shall meet to discuss, review and attempt to resolve the dispute. The
Transaction Committee may be assisted by other advisors, including accountants,
attorneys, and employees, in its discussions and review.

                  (b) If the Transaction Committee is unable to reach an
agreement under clause (a) above within thirty (30) days of the Initial Notice,
then each of the Company, Metrowerks and such Stockholder(s) shall call for a
higher level resolution discussion, pursuant to which Metrowerks shall designate
in writing by notice to the Company and such Stockholder(s) within ten (10) days
after the expiration of such thirty (30) day period a higher level management

                                       7
<PAGE>

employee which shall be the President of SPS, or an equivalent position, as the
case may be, (a "High Level Management Employee") to discuss and attempt to
resolve the dispute. Such High Level Management Employee may be assisted by
other advisors, including accountants, attorneys, and employees, in his or her
discussions and negotiations with the other party. The Company, such
Stockholder(s) and Metrowerks agree to negotiate in good faith with one another
for an additional period ending sixty (60) days after the date of the Initial
Notice.

                  (i) In the event the dispute remains unresolved after the
         passage of sixty (60) days after the date of the Initial Notice, then
         such parties may attempt to settle any claim or controversy arising out
         of it through consultation and negotiation in good faith and a spirit
         of mutual cooperation. If those attempts fail, then the dispute will be
         mediated by a mutually-acceptable mediator to be chosen by Metrowerks,
         the Company and such Stockholder(s) (the "Mediator"). Neither the
         Company, Metrowerks nor such Stockholder(s) may unreasonably withhold
         consent to the selection of a mediator, and the Company, Metrowerks and
         such Stockholder(s) will share the costs of the mediation equally.

                  (c) Any dispute which the Company, Metrowerks and the
Stockholder(s) cannot resolve through negotiation or mediation within ninety
(90) days of the date of the initial demand for it by any of the Company,
Metrowerks or such Stockholder(s) may then be submitted to the courts within the
State of Delaware for resolution. The use of any procedures under this Section
5.10 will not be construed under the doctrines of laches, waiver or estoppel to
affect adversely the rights of either party, and nothing in this paragraph will
prevent either the Company, the Stockholder(s) or Metrowerks from resorting to
judicial proceedings if (a) good faith efforts to resolve the dispute under
these procedures have been unsuccessful or (b) interim relief from a court is
necessary to prevent serious and irreparable injury to one party or to others.

         5.11 INDEMNIFICATION. Each Stockholder and the Company agrees,
severally and not jointly, from and after the date of this Agreement until the
first anniversary hereof, to indemnify and hold harmless Metrowerks and
Metrowerks' general partners, if any (collectively, the "Indemnitees"), against
any investigations, proceedings, claims or actions and for any expenses,
damages, liabilities or losses (joint or several) arising out of such
investigations, proceedings, claims or actions that arise out of or are based
upon any breach of any representation, warranty, agreement or covenant of the
Company and the Stockholders contained herein; provided, however, that such
indemnification shall be limited to the amounts paid by Metrowerks to such
Stockholder or the Company pursuant to (i) in the case of Canopy and Caldera,
the Stock Purchase Agreement, and (ii) in the case of the Company and Sparks,
the Warrant Purchase Agreement and the Warrant (including all sums, if any, paid
upon exercise of the Warrant). Upon written request, each Stockholder and the
Company agrees to reimburse the Indemnitee for any legal or other expenses
reasonably incurred in connection with investigating or defending any such
investigations, proceedings, claims or actions, as such expenses or other costs
are incurred. The Indemnitee may select their own counsel.

                                       8

         5.12 COUNTERPARTS. This Agreement may be executed in any number of
counterparts, including counterparts transmitted by telecopier or telefax, each
of which may be executed by less than all of the Stockholders, each of which
shall be enforceable against the parties actually executing such counterparts,
and all of which together shall constitute one and the same instrument.

         6.8      REMEDIES; SEVERABILITY.

         It is specifically understood and agreed that any breach of the
provisions of this Agreement by any person subject hereto will result in
irreparable injury to the other parties hereto, that the remedy at law alone
will be an inadequate remedy for such breach, and that, in addition to any other
remedies which they may have, such other parties may enforce their respective
rights by actions for specific performance (to the extent permitted by law). The
Company may refuse to recognize any unauthorized transferee as one of its
stockholders for any purpose, including, without limitation, for purposes of
dividend and voting rights, until the relevant party or parties have complied
with all applicable provisions of this Agreement. Whenever possible, each
provision of this Agreement shall be interpreted in such a manner as to be
effective and valid under applicable law, but if any provision of this Agreement
shall be deemed prohibited or invalid under such applicable law, such provision
shall be ineffective to the extent of such prohibition or invalidity, and such
prohibition or invalidity shall not invalidate the remainder of such provision
or the other provisions of this Agreement.

         6.9      MEDIATION AND ALTERNATIVE DISPUTE RESOLUTION.

         In the event that after the date hereof, there is any dispute between
the Investor and the Company, then the following procedure shall be followed:

         (a) Upon the occurrence of such a dispute either the Company or the
Investor may by written notice (the "Initial Notice") to the other party call
for the consideration of such dispute by the Company, on the one hand, and the
general manager of the Metrowerks Division of Motorola's Semiconductor Products
Sector ("SPS"), or such person's successor (such persons, the "Transaction
Committee"). The Transaction Committee shall meet to discuss, review and attempt
to resolve the dispute. The Transaction Committee may be assisted by other
advisors, including accountants, attorneys, and employees, in its discussions
and review.

         (b) If the Transaction Committee is unable to reach an agreement under
clause (a) above within thirty (30) days of the Initial Notice, then each of the
Investor and the Company shall call for a higher level resolution discussion,
pursuant to which the Investor shall designate in writing by notice to the
Company within ten (10) days after the expiration of such thirty (30) day period
a higher level management employee which shall be the President of SPS, or an
equivalent position, as the case may be, (a "High Level Management Employee") to
discuss and attempt to resolve the dispute. Such High Level Management Employee
may be assisted by other advisors, including accountants, attorneys, and
employees, in his or her discussions and negotiations with the other party. The
Company and the Investor agree to negotiate in good faith

                                       17
<PAGE>

with one another for an additional period ending sixty (60) days after the date
of the Initial Notice.

                  (i) In the event the dispute remains unresolved after the
                  passage of sixty (60) days after the date of the Initial
                  Notice, then such parties may attempt to settle any claim or
                  controversy arising out of it through consultation and
                  negotiation in good faith and a spirit of mutual cooperation.
                  If those attempts fail, then the dispute will be mediated by a
                  mutually-acceptable mediator to be chosen by the Investor and
                  the Company (the "Mediator"). Neither the Investor nor the
                  Company may unreasonably withhold consent to the selection of
                  a mediator, and the Investor and the Company will share the
                  costs of the mediation equally.

         (c) Any dispute which the Investor and the Company cannot resolve
through negotiation or mediation within ninety (90) days of the date of the
initial demand for it by either the Investor or the Company may then be
submitted to the courts within the State of Delaware for resolution. The use of
any procedures under this Section 6.9 will not be construed under the doctrines
of laches, waiver or estoppel to affect adversely the rights of either party,
and nothing in this paragraph will prevent either the Company or the Investor
from resorting to judicial proceedings if (a) good faith efforts to resolve the
dispute under these procedures have been unsuccessful or (b) interim relief from
a court is necessary to prevent serious and irreparable injury to one party or
to others.

         (d) Notwithstanding any of the procedures set forth in this Section
6.9, any controversy involving intellectual property may be brought immediately
to the federal courts within the State of Delaware for resolution without
resorting to the Transaction Committee or mediation provisions set forth herein.

         6.10     INDEMNIFICATION.

         The Company agrees to indemnify the Investor and the Investor's general
partners, if any (collectively, the "Indemnitees"), from and after the Closing
Date, and until the one year anniversary thereof, against any investigations,
proceedings, claims or actions and for any expenses, damages, liabilities or
losses (joint or several) arising out of such investigations, proceedings,
claims or actions that arise out of or are based upon any breach of any
representation, warranty, agreement or covenant of the Company contained herein;
provided, however, that any such indemnification shall be limited to the
Purchase Price, and any sums paid upon exercise of the Warrant; and provided
further that the Company's indemnification obligations hereunder against any
investigations, proceedings, claims or actions and for any expenses, damages,
liabilities or losses (joint or several) arising out of such investigations,
proceedings, claims or actions that arise out of or are based upon any breach of
the representations and warranties contained in Section 2.10(g) hereof shall
survive indefinitely. Upon written request, the Company agrees to reimburse the
Indemnitee for any legal or other expenses reasonably incurred in connection
with investigating or defending any such investigations, proceedings, claims or
actions, as such expenses or other costs are incurred. The Indemnitee may select
their own counsel.

                                 FORM OF WARRANT

THE SECURITIES EVIDENCED BY THIS WARRANT HAVE NOT BEEN REGISTERED UNDER THE
SECURITIES ACT OF 1933, AS AMENDED, OR APPLICABLE STATE SECURITIES LAWS, AND NO
INTEREST MAY BE SOLD, DISTRIBUTED, ASSIGNED, OFFERED, PLEDGED OR OTHERWISE

No. W- 1                                        WARRANT TO PURCHASE
ISSUED:  _______, 2000                          COMMON STOCK

                                   LINEO, INC.

                                     WARRANT

         THIS IS TO CERTIFY that, for good and valuable consideration and
subject to these terms and conditions, Metrowerks Holdings, Inc., a Delaware
corporation, or such person to whom this Warrant is transferred (the "Holder"),
is entitled to exercise this Warrant to purchase 2,000,000 fully paid and
nonassessable shares of Lineo, Inc., a Delaware corporation (the "Company"),
Common Stock (the "Warrant Shares") at a price per share of $6.00 (the "Per
Share Exercise Price") (such number of shares, type of security and the Per
Share Exercise Price being subject to adjustment as provided below).

         1.       METHOD OF EXERCISE

         1.1      Cash Exercise Right

         This Warrant may be exercised by the Holder, at any time after the date
issued, but not later than September __, 2002 (the "Exercise Period"), in whole
or in part, by delivering to the Company at Lineo, Inc., 390 South 400 West,
Lindon, UT 84042 (or such other office or agency of the Company as it may
designate by notice in writing to the Holder at the address of the Holder
appearing on the books of the Company) (a) this Warrant certificate, (b) a
certified or cashier's check payable to the Company in the amount of the Per
Share Exercise Price multiplied by the number of shares for which this Warrant
is being exercised

                                   Exhibit A
                                       1
<PAGE>

(the "Purchase Price"), and (c) the Notice of Cash Exercise attached as Exhibit
A duly completed and executed by the Holder.

         1.2      NET ISSUANCE RIGHT

         Notwithstanding the payment provisions set forth above, the Holder may
elect to convert this Warrant into Warrant Shares by surrendering this Warrant
at the office of the Company at the address set forth in Section 1.1 and
delivering to the Company the Notice of Net Issuance Exercise attached as
Exhibit B duly completed and executed by the Holder, in which case the Company
shall issue to the Holder the number of Warrant Shares of the Company equal to
the result obtained by (a) subtracting B from A, (b) multiplying the difference
by C, and (c) dividing the product by A as set forth in the following equation:

X = (A - B) x C  where:
    -----------
          A

                  X   =    the number of Warrant Shares issuable upon net
                           issuance exercise pursuant to the provisions of this
                           Section 1.2.

                  A   =    the Fair Market Value (as defined below) of one
                           Warrant Share on the date of net issuance exercise.

                  B   =    the Per Share Exercise Price for one Warrant Share
                           under this Warrant.

                  C   =    the number of Warrant Shares as to which this
                           Warrant is exercisable pursuant to the provisions of
                           Section 1.1.

         If the foregoing calculation results in a negative number, then no
Warrant Shares shall be issued upon net issuance exercise pursuant to this
Section 1.2.

         "Fair Market Value" shall mean:

         (a) if a sale of securities or net issuance exercise is in connection
with a transaction specified in Section 4.4(b), the value of the consideration
(determined, in the case of noncash consideration, in accordance with Section
2(d) of that certain Certificate of Designation of the Company filed with the
Delaware Secretary of State on May 3, 2000) to be received pursuant to such
transaction by the holder of one Warrant Share;

         (b) if a sale of securities or net issuance exercise is in connection
with the initial public offering or private placement of the Company's shares
(the "Shares"), the price (before deducting commission, discounts or expenses)
at which such securities are sold in such offering or private placement,
proportionately adjusted as a result of any adjustments arising from the
conversion of the Warrant Shares into Shares in contemplation of such public
offering;

                                   Exhibit A
                                       2
<PAGE>

         (c) if a sale of securities or net issuance exercise is after the
occurrence of the initial public offering of the Company's securities:

                  (i) if the Company's securities are traded on an exchange or
are quoted on the Nasdaq National Market, the average of the closing or last
sale price reported for the ten business days immediately preceding the date of
net issuance exercise;

                  (ii) if the Company's securities are not traded on an exchange
or on the Nasdaq National Market, but are traded in the over-the-counter market,
the average of the closing bid and asked prices reported for the ten market days
immediately preceding the date of net issuance exercise; and

         (d) In all other cases, the "Fair Market Value" of the securities shall
be the fair market value thereof as determined in accordance with the Appraisal
Procedure (as defined in Section 10.7), using any appropriate valuation method,
assuming an arms-length sale to an independent party.

         2.       DELIVERY OF STOCK CERTIFICATES; NO FRACTIONAL SHARES

         2.1      Within 10 days after the payment of the Purchase Price
following the exercise of this Warrant (in whole or in part) or after notice of
net issuance exercise and compliance with Section 1.2, the Company at its
expense shall issue in the name of and deliver to the Holder (a) a certificate
or certificates for the number of fully paid and nonassessable Warrant Shares to
which the Holder shall be entitled upon such exercise, and (b) a new Warrant in
substantially the same form to purchase up to that number of Warrant Shares, if
any, as to which this Warrant has not been exercised if this Warrant has not
expired. The Holder shall for all purposes be deemed to have become the holder
of record of such Warrant Shares on the date this Warrant was exercised (the
date the Holder has fully complied with the requirements of Section 1.1 or 1.2),
irrespective of the date of delivery of the certificate or certificates
representing the Warrant Shares; provided that, if the date such exercise is
made is a date when the stock transfer books of the Company are closed, such
person shall be deemed to have become the holder of record of such Warrant
Shares at the close of business on the next succeeding date on which the stock
transfer books are open.

         2.2      No fractional shares shall be issued upon the exercise of this
Warrant. In lieu of fractional shares, the Company shall pay the Holder a sum in
cash equal to the fair market value of the fractional shares (as determined
pursuant to Section 2.1 hereof) on the date of exercise.

         3.       COVENANTS AS TO WARRANT SHARES

         The Company covenants that at all times during the Exercise Period
there shall be reserved for issuance and delivery upon exercise of this Warrant
such number of Warrant Shares as is necessary for exercise in full of this
Warrant and, from time to time, it will take

                                   Exhibit A
                                       3

<PAGE>

all steps necessary to amend the Certificate of Incorporation to provide
sufficient reserves of Warrant Shares.

         4.       ADJUSTMENTS FOR CERTAIN DILUTIVE ISSUANCES

         The number of shares of Common Stock for which this Warrant is
exercisable and the exercise price shall be subject to adjustment from time to
time as set forth in this Section 4.

         4.1      UPON ISSUANCE OF COMMON STOCK

         If the Company shall, at any time or from time to time after the date
hereof (the "Original Issue Date"), issue (a) any shares of Common Stock other
than options to purchase or rights to subscribe for Common Stock (other than an
issuance of Common Stock as a dividend, subdivision or split in respect of which
the adjustment provided for in Section 4.3 applies), (b) securities by their
terms convertible into or exchangeable for Common Stock, or (c) options to
purchase or rights to subscribe for such convertible or exchangeable securities,
without consideration or for consideration per share less than the applicable
Per Share Exercise Price in effect immediately prior to the issuance of such
Common Stock or securities, then such applicable Per Share Exercise Price shall
forthwith be lowered to a price equal to the price obtained by multiplying:

                  (i) the applicable Per Share Exercise Price in effect
immediately prior to the issuance of such Common Stock or securities by

                  (ii) a fraction of which (x) the denominator shall be the
number of shares of Common Stock outstanding on a fully-diluted basis (after
giving effect to the conversion or exercise, as the case may be, of all
convertible securities, warrants, options, or other rights to purchase or
acquire capital stock of the Company) immediately after such issuance and (y)
the numerator shall be the sum of (i) the number of shares of Common Stock
outstanding on a fully-diluted basis (after giving effect to the conversion or
exercise, as the case may be, of all convertible securities, warrants, options,
or other rights to purchase or acquire capital stock of the Company) immediately
prior to the date of such issuance and (ii) the number of additional shares of
Common Stock which the aggregate consideration for the number of shares of
Common Stock so offered would purchase at the applicable Per Share Exercise
Price.

         4.2      PROVISIONS APPLICABLE TO ADJUSTMENTS

         For the purposes of any adjustment of the applicable Per Share Exercise
Price pursuant to Section 4.1, in the case of the issuance of options to
purchase or rights to subscribe for Common Stock, securities by their terms
convertible into or exchangeable for Common Stock, or options to purchase or
rights to subscribe for such convertible or exchangeable securities:

                                    (A) the aggregate maximum number of shares
of Common Stock deliverable upon exercise of such options to purchase or rights
to subscribe for Common Stock shall be deemed to have been issued at the time
such options or rights were

                                   Exhibit A
                                        4

<PAGE>

issued and for a consideration equal to the Fair Market Value of the
consideration, if any, received by the Company upon the issuance of such options
or rights plus the minimum purchase price provided in such options or rights for
the Common Stock covered thereby;

                                    (B) the aggregate maximum number of shares
of Common Stock deliverable upon conversion of or in exchange of any such
convertible or exchangeable securities or upon the exercise of options to
purchase or rights to subscribe for such convertible or exchangeable securities
and subsequent conversion or exchange thereof shall be deemed to have been
issued at the time such securities, options, or rights were issued and for a
consideration equal to the Fair Market Value of the consideration received by
the Company for any such securities and related options or rights (excluding any
cash received on account of accrued interest or accrued dividends), plus the
Fair Market Value of the additional consideration, if any, to be received by the
Company upon the conversion or exchange of such securities or the exercise of
any related options or rights; and

                                    (C) on any change in the number of shares or
exercise price of Common Stock deliverable upon exercise of any such options or
rights or conversions of or exchanges for such securities, other than a change
resulting from the antidilution provisions thereof, the applicable Per Share
Exercise Price shall forthwith be readjusted to such Per Share Exercise Price as
would have been obtained had the adjustment made upon the issuance of such
options, rights or securities not converted prior to such change or options or
rights related to such securities not converted prior to such change been made
upon the basis of such change.

                                    (D) No further adjustment of the applicable
Per Share Exercise Price adjusted upon the issuance of any such options, rights,
convertible securities or exchangeable securities shall be made as a result of
the actual issuance of Common Stock on the exercise of any such rights or
options or any conversion or exchange of any such securities.

         4.3      ADJUSTMENTS FOR STOCK SPLITS, DIVIDENDS

         If the Company shall subdivide the number of outstanding shares of its
Common Stock into a greater number of shares, then the Per Share Exercise Price
in effect before such dividend or subdivision shall be proportionately reduced
and the number of Warrant Shares at that time issuable pursuant to the exercise
of this Warrant shall be proportionately increased; and, conversely, if the
Company shall reduce the number of outstanding shares of its Common Stock by
combining such shares into a smaller number of shares, then the Per Share
Exercise Price in effect before such combination shall be proportionately
increased and the number of Warrant Shares at that time issuable pursuant to the
exercise or conversion of this Warrant shall be proportionately decreased. Each
adjustment in the number of Warrant Shares issuable shall be to the nearest
whole share.

                                   Exhibit A
                                       5
<PAGE>

         4.4      EFFECT OF REORGANIZATION

                  (a)      REORGANIZATION--NO CHANGE IN CONTROL

         Upon a merger, consolidation, acquisition of all or substantially all
of the property or stock, liquidation or other reorganization of the Company
(collectively, a "Reorganization") during the Exercise Period, as a result of
which the stockholders of the Company receive cash, stock or other property in
exchange for their Warrant Shares and the holders of the Company's voting equity
securities immediately prior to such Reorganization together own a majority
interest of the voting equity securities of the successor corporation following
such Reorganization, lawful provision shall be made so that the Holder shall
thereafter be entitled to receive, upon exercise of this Warrant, the number of
shares of securities of the successor corporation resulting from such
Reorganization (and cash and other property), to which a holder of the Warrant
Shares issuable upon exercise of this Warrant would have been entitled in such
Reorganization if this Warrant had been exercised immediately prior to such
Reorganization. In any such case, appropriate adjustment (as determined in good
faith by the Company's Board of Directors and reasonably acceptable to the
Holder) shall be made in the application of the provisions of this Warrant with
respect to the rights and interest of the Holder after the Reorganization to the
end that the provisions of this Warrant (including adjustments of the Per Share
Exercise Price and the number and type of securities purchasable pursuant to the
terms of this Warrant) shall be applicable after that event, as near as
reasonably may be, in relation to any shares deliverable after that event upon
the exercise of this Warrant.

                  (b)      REORGANIZATION--CHANGE IN CONTROL; TERMINATION OF
WARRANT

         Upon Reorganization during the Exercise Period, as a result of which
the stockholders of the Company receive cash, stock or other property in
exchange for their Warrant Shares and the holders of the Company's voting equity
securities immediately prior to such Reorganization together own less than a
majority interest of the voting equity securities of the successor corporation
following such Reorganization, the Holder shall be given notice of such proposed
action as provided in Section 7. The Holder may attend the meeting of the
Company's stockholders at which such action is considered and voted upon. If the
proposed action is approved according to applicable law by the stockholders of
all corporations or other entities that are parties to the proposed action, the
Holder shall be so notified in writing by the Company by registered or certified
mail at least 10 days before its effectiveness. Notwithstanding the period of
exercisability stated in Section 1.1 of this Warrant, this Warrant shall become
forever null and void to the extent not exercised on or before 5:00 p.m.,
Pacific time, on the seventh day following the delivery of such notice; provided
that if the Reorganization does not close, this Warrant shall not terminate and
the Exercise Period shall continue as stated in Section 1.1 of this Warrant.

         4.5      CERTIFICATE AS TO ADJUSTMENTS

         In the case of any adjustment in the Per Share Exercise Price or number
and type of securities issuable upon exercise of this Warrant, the Company will
promptly give written

                                   Exhibit A
                                       6
<PAGE>

notice to the Holder in the form of a certificate, certified and confirmed by an
officer of the Company, setting forth the adjustment in reasonable detail.

         4.6      DEFERRAL IN CERTAIN CIRCUMSTANCES

         In any case in which the provisions of this Section 4 shall require
that an adjustment shall become effective immediately after a record date of an
event, the Company may defer until the occurrence of such event issuing to the
Holder of any Warrant exercised after such record date and before the occurrence
of such event the shares of capital stock issuable upon such exercise by reason
of the adjustment required by such event and issuing to such Holder only the
shares of capital stock issuable upon such exercise before giving effect to such
adjustments; provided, however, that the Company shall deliver to such Holder an
appropriate instrument or due bills evidencing such Holder's right to receive
such additional shares.

         4.7      APPRAISAL PROCEDURE

         In any case in which the provisions of this Section 4 shall necessitate
that the Appraisal Procedure be utilized for purposes of determining an
adjustment to the applicable Per Share Exercise Price, the Company may defer
until the completion of the Appraisal Procedure and the determination of the
adjustment (1) issuing to the Holder of any Warrant exercised after the date of
the event that requires the adjustment and before completion of the Appraisal

         10.7     APPRAISAL PROCEDURE

         "Appraisal Procedure," if applicable, means the following procedure to
determine the fair market value, as to any security, for purposes of the
definition of "Fair Market Value" or the fair market value, as to any other
property (in either case, the "valuation amount"). The valuation amount shall be
determined in good faith jointly by the Company's Board of Directors (the
"Board") and the Holder; provided, however, that if such parties are not able to
agree on the valuation amount within a reasonable period of time (not to exceed
twenty (20) days) the valuation amount shall be determined by an investment
banking firm of national recognition, which firm shall be reasonably acceptable
to the Board and the Holder. If the Board and the Holder are unable to agree
upon an acceptable investment banking firm within ten (10) days after the date
either party proposed that one be selected, the investment banking firm will be
selected by an arbitrator located in San Francisco, California, selected by the
American Arbitration Association (or if such organization ceases to exist, the
arbitrator shall be chosen by a court of competent jurisdiction). The arbitrator
shall select the investment banking firm (within ten (10) days of his
appointment) from a list, jointly prepared by the Board and the Holder, of not
more than six investment banking firms of national standing in the United
States, of which no more than three may be named by the Board and no more than
three may be named by the Holder. The arbitrator may consider, within the
ten-day period allotted, arguments from the parties regarding which investment
banking firm to choose, but the selection by the arbitrator shall be made in its
sole discretion from the list of six. The Board and the Holder shall submit
their respective valuations and other relevant data to the investment banking
firm, and the investment banking firm shall as soon as practicable thereafter
make its own determination of the valuation amount. The final valuation amount
for purposes hereof shall be the average of the two valuation amounts closest
together, as determined by the investment banking firm, from among the valuation
amounts submitted by the Company and the Holder and the valuation amount
calculated by the investment banking

firm. The determination of the final valuation amount by such investment banking
firm shall be final and binding upon the parties. The Company shall pay the fees
and expenses of the investment banking firm and arbitrator (if any) used to
determine the valuation amount. If required by any such investment banking firm
or arbitrator, the Company shall execute a retainer and engagement letter
containing reasonable terms and conditions, including, without limitation,
customary provisions concerning the rights of indemnification and contribution
by the Company in favor of such investment banking firm or arbitrator and its
officers, directors, partners, employees, agents and affiliates.

SECTION 2.12  LITIGATION:

                  Although Lineo does not have any pending litigation, one of
         Lineo's suppliers, Viosoft, Inc., has threatened to take action in
         response to Lineo's contention that Viosoft breached a development
         contract with Lineo. The contract, dated November 4, 1999, required
         Viosoft to develop and ship to Lineo a customer ready version of its
         IDE in April 2000. Viosoft failed to do so. Lineo gave Viosoft notice
         of the breach and Viosoft failed to cure the breach, so on June 29,
         2000, Lineo gave Viosoft notice of termination of the contract.
         Including annual commitments, Lineo's total obligation under the
         contract for payments to Viosoft would have been $450,000 of which
         Lineo has already paid $112,500. Lineo has demanded repayment of this
         amount. Lineo believes that Viosoft has no valid claim against Lineo
         and if litigation arises, Lineo intends to defend itself vigorously and
         seek damages from Viosoft. Regardless of the outcome of any litigation,
         Lineo does not believe it will have a material adverse impact on
         Lineo's business or its financial health. Lineo has not yet determined
         whether it will initiate a lawsuit.
