                                 LOAN AGREEMENT

         THIS LOAN AGREEMENT, as amended, modified or otherwise supplemented
from time to time (this "Agreement"), is made and entered into by and between
THE CANOPY GROUP, INC., a Utah corporation ("LENDER"), and THE SANTA CRUZ
OPERATION, INC., a California corporation ("BORROWER"), who, for good and
valuable consideration, the adequacy and receipt of which is acknowledged, agree
as follows.

                                    ARTICLE 1
                                      LOAN

         1.1 Loan. Subject to the terms and conditions hereof, Lender shall make
a loan or loans, each a "LOAN" or collectively, the "LOANS" from time to time to
Borrower, and Borrower may borrow from Lender, an aggregate amount of up to
Eighteen Million Dollars ($18,000,000.00) upon the terms and conditions set
forth in the form of Promissory Note attached hereto as EXHIBIT A (the "NOTE").
The closing of the Loan shall occur on December ___, 2000 (the "CLOSING DATE").

         1.2 Loan Fees. Borrower shall pay to Lender a fee for originating the
Loans in the amount of Ninety Thousand Dollars ($90,000.00) on the later of (i)
the Closing Date, or (ii) immediately upon receipt of funding by Caldera
Systems, Inc. ("CALDERA") pursuant to the $7,000,000 loan referenced in the
Intercreditor Agreement by and between Lender and Caldera dated on or about even
date hereof ("INTERCREDITOR AGREEMENT").

         1.3 Collateral. In addition to any other collateral described in any
other documents executed in connection with the Loans (which documents, together
with this Agreement, the Note and the other documents referred to in this
Section, constitute the "LOAN DOCUMENTS"), the Loans shall be secured by a
perfected security interest in "COLLATERAL" as that term is defined in the form
of Security Agreement attached hereto as EXHIBIT B (the "SECURITY AGREEMENT").
The security interest of Lender hereunder shall be junior in priority only to
the Prior Liens as that term is defined in the Security Agreement.

                                    ARTICLE 2
                         REPRESENTATIONS AND WARRANTIES

         Borrower makes the following representations and warranties to Lender
as of the date hereof and as of the Closing Date:

         2.1 Organization and Qualification. Borrower is a corporation duly
organized and existing in good standing under the laws of the State of
California. Borrower is duly qualified to do business in each jurisdiction where
the conduct of its business requires qualification and where the failure to be
so qualified could reasonably be expected to have a material adverse

<PAGE>   2

effect on the business, assets, operations, or financial condition of Borrower
("MATERIAL ADVERSE EFFECT"). Borrower has the full power and authority to own
its properties and to conduct the business in which it engages and to enter into
and perform its obligations under the Loan Documents, and all agreements,
documents, obligations, and transactions contemplated by this Agreement.

         2.2 Authorization. The execution, delivery, and performance by Borrower
of the Loan Documents and all agreements, documents, obligations, and
transactions contemplated by this Agreement have been duly authorized by all
necessary action on the part of Borrower and are not inconsistent with
Borrower's articles of incorporation or by-laws, each as currently in effect, do
not and will not contravene any provision of, or constitute a default under, any
material indenture, mortgage, contract, or other instrument to which Borrower is
a party or by which Borrower is bound. Upon their execution and delivery, the
Loan Documents will constitute legal, valid, and binding agreements and
obligations of Borrower, enforceable in accordance with their respective terms,
except as limited by bankruptcy, insolvency or other laws of general application
relating to or affecting the enforcement of creditors' rights generally and
general principles of equity.

         2.3 Pending Litigation. There is no action, suit or proceeding pending
or to the best of Borrower's knowledge, threatened, against or affecting
Borrower or the Collateral, in any court of law or equity or before any
governmental or quasi-governmental instrumentality, whether federal, state,
county or municipal, which would materially and adversely affect Borrower's
ability to perform under the Loan Documents.

         2.4 Financial Statements and Other Information. Any and all financial
statements delivered to Lender by Borrower are in all material respects
accurate, complete, prepared in accordance with generally accepted accounting
principles consistently applied, and fairly present in all material respects the
financial condition of Borrower. No material adverse change has occurred in the
financial condition of Borrower reflected therein since September 30, 2000 and
no additional borrowings have been made by Borrower since September 30, 2000
other than the borrowing contemplated hereby, or approved by Lender.

         2.5 Collateral. The Collateral, and any and all improvements thereon,
are free and clear of all liens and encumbrances, excepting Prior Liens and
Permitted Liens (as those terms are defined in the Security Agreement), and
Borrower has sole title to the owned portions thereof.

         2.6 Commission Filings. Borrower has properly and timely filed with the
Securities and Exchange Commission (the "COMMISSION") all reports, proxy
statements, forms and other documents required to be filed with the Commission
under the Exchange Act since January 1999 (the "COMMISSION FILINGS"), except for
the filing of form 10-Q for the third quarter ended June 30, 2000. As of their
respective dates, (i) the Commission Filings complied in all material respects
with the requirements of the Securities Act of 1933 (the "SECURITIES ACT") or
the Exchange Act, as the case may be, and the rules and regulations of the
Commission promulgated

                                       2
<PAGE>   3

thereunder applicable to such Commission Filings, and (ii) none of the
Commission Filings contained at the time of its filing 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. The financial
statements of Borrower included in the Commission Filings, as of the dates of
such documents, were true and complete in all material respects and complied
with applicable accounting requirements and the published rules and regulations
of the Commission with respect thereto, were prepared in accordance with
generally accepted accounting principles in the United States ("GAAP") (except
in the case of unaudited statements permitted by under the Exchange Act) applied
on a consistent basis during the periods involved (except as may be indicated in
the notes thereto) and fairly presented in all material respects the
consolidated financial position of Borrower and its subsidiaries as of the dates
thereof and the consolidated results of their operations and cash flows for the
periods then ended (subject, in the case of unaudited statements, to normal
year-end audit adjustments that in the aggregate are not material and to any
other adjustment described therein).

                                    ARTICLE 3
                              CONDITIONS PRECEDENT

         As a condition precedent to the disbursement of any Loan proceeds, all
of the following conditions must be fully satisfied, as determined by Lender in
Lender's sole discretion, by the Closing Date:

         3.1 Authority. Borrower has delivered to Lender a copy of Borrower's
organizational documents, together with all amendments, and an original
certificate of resolutions of Borrower acceptable to Lender. Borrower also has
delivered to Lender such other evidence of Borrower's good standing and
authority as Lender may reasonably request.

         3.2 Opinion of Counsel. Borrower has delivered to Lender an opinion
from Borrower's counsel in form and content reasonably satisfactory to Lender.

         3.3 Delivery of Loan Documents. All of the Loan Documents requested by
Lender have been fully executed and the original executed documents delivered to
Lender.

         3.4 Recording and Filing of Loan Documents. All of the Loan Documents
which require filing or recording have been properly filed and recorded so that
all of the liens and security interests granted to Lender in connection with the
Loan will be properly created and perfected as described herein.

         3.5 Warrants. Lender shall have received from Borrower, in form and
content reasonably acceptable to Lender, a 2 year warrant to purchase 2,250,000
shares of Borrower's Common Stock ("INITIAL WARRANT") at an exercise price equal
to the closing price of Borrower's Common Stock on the date of this Agreement
("EXERCISE PRICE"). Additional warrants to purchase shares of Borrower's Common
Stock ("ADDITIONAL WARRANTS") shall be issued by Borrower and delivered to
Lender when requests for advances are made and the aggregate

                                       3
<PAGE>   4

amount advanced to Borrower under the Loan Documents exceeds $9,000,000. The
number of shares that may be purchased under the Additional Warrants shall equal
the product of the amounts advanced exceeding $9,000,000 multiplied by 0.25,
such product then divided by the Exercise Price. For example, assuming (i) an
Exercise Price of $3.00, (ii) that Borrower has taken advances that, in the
aggregate, equal $8,000,000 and (iii) Borrower requests an advance of an
additional $2,500,000; the request must be accompanied by an Additional Warrant
to purchase 125,000 shares of Borrower's Common Stock. That is, $1,500,000 (the
amount of the request that is over the $9,000,000 aggregate limit), multiplied
by 0.25 equals $375,000, which is then divided by the Exercise Price of $3.00 to
arrive at 125,000 shares.

         3.6 Conditions Precedent Not Met. In the event that any of the
requirements under Sections 3.1 through 3.5 have not been satisfied by December
29, 2000, then either party may terminate this Agreement and the Loan Documents
by providing written notice of termination. Upon delivery of written notice,
this Agreement and the Loan Documents shall automatically terminate and become
null and void. In such event, each party shall bear their own costs and expenses
and have no further obligation whatsover to the other party.

                                    ARTICLE 4
                              COVENANTS OF BORROWER

         Borrower agrees and covenants with Lender as follows:

         4.1 Further Documentation. Upon Lender's written request and at
Borrower's sole expense, Borrower will promptly and duly execute and deliver
such further instruments and documents and take such further action as Lender
may reasonably request for the purpose of obtaining, giving notice of,
protecting, preserving and perfecting the security interests granted under this
Agreement, including, without limitation, the filing of any financing or
continuation statements under the Uniform Commercial Code (the "CODE") in effect
in any jurisdiction with respect to the security interests created hereby, the
recording of the security interests granted hereunder in any intellectual
property with the appropriate governmental or other authorities in any
jurisdiction. Borrower agrees that a carbon, photographic or other reproduction
of this Agreement (or, if appropriate, any other Loan Document) will be
sufficient as a financing statement for filing in any jurisdiction.

         4.2 Maintenance of Records. Borrower will keep and maintain records of
the Collateral as it does in the ordinary course of business. For Lender's
further security, Lender will have a security interest in all of the books and
records of Borrower pertaining to the Collateral.

         4.3 No Liens on Collateral. Borrower will not create, incur or permit
to exist, will defend the Collateral against, and will take such other action as
is necessary to remove, any lien, claim, security interest or encumbrance on or
to any of the Collateral, other than Permitted Liens and Prior Liens, and liens
granted to Lender under the Loan Documents.

                                       4
<PAGE>   5

         4.4 Limitation on Dispositions of Collateral. Borrower will use all
commercially reasonable efforts to preserve the Collateral without material
impairment while conducting its business in the ordinary course in a manner that
is consistent with Borrower's past business practices. Borrower will not,
through any license, encumbrance, assignment, transfer or disposition of any of
the Collateral, any creation of obligations of Borrower, any issuance of
securities, or any other action, (i) avoid or seek to avoid the observation or
performance of any of the terms to be observed or performed by Borrower under
any Loan Document, (ii) materially impair the benefit of any Loan Document or
the Collateral to Lender, or (iii) materially and adversely affect Lender's
ability to operate, or obtain the financial or economic benefit of, the
Collateral in accordance with the terms of the Loan Documents; provided,
however, that Borrower may (A) enter into licenses with third parties in the
ordinary course of its business and consistent with its past licensing practice
of Intellectual Property (as defined in the Security Agreement) owned or
licensed by Borrower, (B) sell or otherwise dispose of worn-out or obsolete
Equipment or Fixtures (each as defined in the Security Agreement), and (C)
fulfill its obligations under the Agreement and Plan of Reorganization dated
July 31, 2000 by and between Borrower and Caldera ("REORGANIZATION AGREEMENT").
Borrower will at all times in good faith take, and assist in taking, all such
action as may be necessary or appropriate to protect Lender's rights under the
Loan Documents from impairment and to preserve for Lender's benefit the value of
the Collateral.

         4.5 No Change in Location, Name, etc. Except upon thirty (30) days
prior written notice to Lender, Borrower will not move any Collateral (other
than as otherwise permitted in the Loan Documents) from their current location
or change Borrower's name, identity or structure to such an extent that any
financing statement or other Loan Document filed by Lender would become
misleading or inaccurate.

         4.6 Payment of Taxes and Assessments. Borrower will pay prior to
delinquency all taxes and assessments assessed against, levied upon or placed
against the Collateral, other than taxes being contested in good faith by
appropriate proceedings and for which adequate reserves are maintained on the
books of the Borrower in accordance with GAAP.

         4.7 Insurance. Borrower shall maintain insurance with respect to the
Collateral in accordance with the insurance standards and practices adhered to
generally by owners of like collateral.

         4.8 Additional Encumbrances. Until the Loan has been repaid in full,
Borrower shall not without the prior written consent of Lender create or incur
or suffer to be created or incurred any encumbrance, mortgage, pledge, lien or
charge of any kind upon any Collateral, other than Permitted Liens.

         4.9 Financial Statements. Borrower covenants that it shall provide
Lender with such financial statements and reports as Lender may reasonably
request, and that such statements and reports shall be prepared in accordance
with generally accepted accounting principles consistently applied and shall
fairly represent in all material respects Borrower's financial

                                       5
<PAGE>   6

condition and the results of its operations for the period or periods covered.
As to all financial statements and reports which Borrower has furnished or may
in the future furnish to Lender, Borrower acknowledges and agrees that it has a
contractual obligation to ensure that such statements and reports fairly present
the financial condition of Borrower in all material respects. If any reasonably
requested financial reports are not timely provided to Lender, and Lender
determines to notify Borrower, in writing, that the same have not been timely
provided, then Borrower shall have thirty (30) days from the date of Lender's
written notice to deliver the delinquent financial reports to Lender. Nothing in
this Section shall be construed to require that Lender give Borrower the written
notice and the additional thirty (30) day grace period to provide delinquent
financial reports as described above. Nothing in this Section shall be construed
to alter, impair or infringe upon Lender's right to declare an Event of Default
as provided in this Agreement or to alter or extend the time limits for cure of
a non-monetary default as provided in this Agreement.

         4.10 Required Notices. Borrower shall give Lender prompt written notice
of the following:

                  a. Any litigation or claims of any kind which might subject
Borrower to any liability in an aggregate amount in excess of $10,000.00,
whether covered by insurance or not, and any litigation involving any Collateral
which could reasonably be expected to have a Material Adverse Effect.

                  b. All complaints made and demand letters sent by any
governmental agency that could reasonably be expected to have a Material Adverse
Effect on the Collateral.

                  c. Any material default under any material contract to which
Borrower is a party or acceleration of any other indebtedness of Borrower.

                  d. Any event or conditions which constitute an Event of
Default or, with the passage of time or the giving of notice, or both, would
constitute an Event of Default.

                  e. Any material adverse change in the financial condition of
Borrower.

         4.11 Change of Business. Borrower shall not modify or change the nature
or type of its business and natural extensions thereof as in effect on the date
hereof and after the sale of substantial assets to Caldera without the prior
written consent of Lender.

         4.12 Reports. Borrower shall keep Lender fully informed as to the
status of Borrower's business by delivering to Lender, upon the written request
of Lender, copies of quarterly operating statements (disbursements, receipts,
etc.), and any other reports regarding the Borrower's business as Lender may
reasonably require.

         4.13 Expenses. All legal and out of pocket expenses of Lender incurred
in connection with negotiating, documenting, processing, consummating or
servicing the Loan and the Loan

                                       6
<PAGE>   7

Documents, not to exceed $5,000.00, shall be paid by Borrower out of Loan
proceeds and may be deducted therefrom by Lender. Borrower agrees to pay all
reasonable expenses, including reasonable attorneys fees and other legal
expenses, incurred by Lender in any bankruptcy proceedings of any type involving
Borrower, any Collateral or the Loan Documents, including, without limitation,
expenses incurred in modifying or lifting the automatic stay, determining
adequate protection, use of cash collateral or relating to any plan of
reorganization.

         4.14 Caldera Stock. Borrower shall deliver or cause to be delivered to
Lender, immediately upon receipt thereof or control thereover, all the common
stock, whether issued by Caldera or Caldera International, Inc. to Borrower in
connection with the Reorganization Agreement together with blank stock powers
for all such stock properly signed by Borrower with signatures guaranteed, all
in form and substance reasonably satisfactory to Lender. Notwithstanding the
foregoing, Borrower shall not be required to deliver those shares issued to
Borrower, whether by Caldera or Caldera International, Inc., in connection with
the Reorganization Agreement that represent (i) the 982,500 shares of common
stock to be used by Borrower to fulfill its prior warrant obligations, or (ii)
the number of shares, which shall not exceed 2,500,000 shares of common stock to
be used in funding employee stock options for those employees of Borrower who
will be transferring to Caldera International, Inc. upon the closing of the
Reorganization Agreement.

                                    ARTICLE 5
                                EVENTS OF DEFAULT

         5.1 Event of Default. Ten (10) days after written notice from Lender to
Borrower for monetary defaults and thirty (30) days after written notice from
Lender to Borrower for non-monetary defaults, if such defaults are not cured
within such ten (10) day or thirty day (30) periods, respectively, each of the
following shall constitute an event of default ("EVENT OF DEFAULT") under this
Agreement:

                  a. Default in Payment. If Borrower fails to make any payment
due and payable under the terms of the Note, this Agreement (and under the terms
of the Intercreditor Agreement) or any other Loan Document.

                  b. Representations and Warranties. If any of the
representations and warranties made by Borrower shall be false or misleading in
any material respect when made.

                  c. Covenants. If Borrower shall be in material default under
any of the material terms, covenants, conditions, or obligations under any Loan
Document.

                  d. Dissolution. If Borrower is dissolved.

                  e. Receiver. If a receiver, trustee, or custodian is appointed
for any part of the Collateral, or any part of the Collateral is assigned for
the benefit of creditors.

<PAGE>   8

                  f. Impairment to Lien. If at any time any Loan Document
creating a lien on any of the Collateral may be impaired by any material lien,
encumbrance or other defect other than the Prior Liens or the Permitted Liens.

                  g. Bankruptcy. If a petition in bankruptcy is filed against
Borrower, and such petition is not dismissed within ninety (90) days of filing,
a petition in bankruptcy is filed by Borrower or a receiver, trustee or
custodian of any part of the Collateral is appointed; or if Borrower files a
petition for reorganization under any of the provisions of the Bankruptcy Act or
any law, State or Federal, or makes an assignment for the benefit of creditors
or is adjudged insolvent by any State or Federal Court of competent
jurisdiction.

                  h. Judgment or Attachment. If a judgment is entered against
Borrower or any attachment be made for an amount in excess of $100,000.00 and
such judgment or attachment is not vacated, discharged, stayed or bonded pending
appeal, paid or otherwise fully satisfied within thirty (30) days of the date it
is entered.

                                    ARTICLE 6
                                    REMEDIES

         6.1 Termination and Acceleration. Upon the occurrence of an Event of
Default, all obligations of Lender under this Agreement, and under the other
Loan Documents at the election of Lender, shall cease and terminate and Lender
may declare all amounts outstanding under the Note and other Loan Documents
immediately due and payable in accordance with the Intercreditor Agreement and
may foreclose the Loan Documents.

         6.2 Rights and Remedies Cumulative. All rights, remedies, and powers
conferred in this Agreement and the other Loan Documents are cumulative and not
exclusive of any other rights or remedies, and shall be in addition to every
other right, power, and remedy that Lender may have, whether specifically
granted in the Loan Documents, or existing at law, in equity, or by statute; and
any and all such rights and remedies may be exercised from time to time and as
often and in such order as Lender may deem expedient. Any forbearance or delay
by Lender in exercising any of its rights, remedies, and powers shall not be
deemed to be a waiver and the exercise or partial exercise of any right, remedy,
or power, and shall not preclude the further exercise of such right, remedy, and
power and the same shall continue in full force and effect until specifically
waived by an instrument in writing executed by Lender.

         6.3 Attorney-in-Fact. Upon the occurrence and during the continuance of
an Event of Default, Borrower hereby irrevocably constitutes and appoints Lender
Borrower's true and lawful attorney-in-fact to execute, acknowledge and deliver
any instruments and to do and perform any act such as referred to herein in the
name and on behalf of Borrower. This power of attorney is irrevocable and is
coupled with an interest.

                                       8

                                    ARTICLE 7
                                  MISCELLANEOUS

         7.1 Non-Waiver. No advance of Loan proceeds under this Agreement shall
constitute a waiver of any of the conditions to be performed by Borrower and in
the event Borrower is unable to satisfy any such conditions Lender shall not be
precluded from declaring such failure to be an Event of Default.

         7.2 Survival. All representations, warranties and covenants of Borrower
shall survive the making of the Loan and the provisions of this Agreement shall
be binding upon Borrower, Borrower's successors and assigns and inure to the
benefit of Lender, Lender's successors and assigns.

         7.3 Derivative Rights. Any obligation of Lender to make disbursements
under this Agreement is imposed solely and exclusively for the benefit of
Borrower and no other person, firm or corporation shall, under any
circumstances, be deemed to be a beneficiary of such condition, nor shall it
have any derivative claim or action against Lender.

         7.4 Conflict. The Loan Documents shall be subject to all the terms,
covenants, conditions, obligations, stipulations and agreements contained in
this Agreement. In the event there is any conflict between the terms and
conditions of this Agreement and any other Loan Document, this Agreement shall
prevail; provided, however, that this Agreement shall be subject to the terms of
the Intercreditor Agreement.

         7.5 Assignment. Lender may assign the Loan Documents, in whole or in
part, to any other person, firm or corporation provided that all provisions of
this Agreement shall continue to apply in conjunction with the other Loan
Documents. In the event of such assignment, it shall be deemed to have been made
in pursuance of this Agreement and not to be a modification of this Agreement,
and the disbursements and advances subsequently made shall be governed by the
Loan Documents. Borrower shall not assign this Agreement, or any interest of
Borrower in or to this Agreement, the Loan proceeds, or any of the Loan
Documents without the prior written consent of Lender. Any dissolution of
Borrower or any transfer of any interest in the Borrower without the prior
written consent of Lender shall be assumed to be an assignment in violation of
this Section.

         7.6 Notices. All notices shall be in writing and shall be deemed to
have been sufficiently given or served when personally delivered, deposited in
the United States mail, by registered or certified mail, or deposited with a

                               SECURITY AGREEMENT

         This Security Agreement, as amended, modified or otherwise supplemented
from time to time (this "AGREEMENT"), is made and entered into as of December
__, 2000 by and between The Santa Cruz Operation, Inc., a California corporation
with principal offices at 425 Encinal, Santa Cruz, California 95061 ("DEBTOR"),
and The Canopy Group, Inc., a Utah corporation, with principal offices at 333
South 520 West, Suite 300, Lindon, Utah 84042 ("SECURED PARTY").

                                 R E C I T A L S

         A. In connection with the execution of the Secured Convertible
Promissory Note of even date herewith (the "NOTE"), and the Loan Agreement of
even date herewith (the "LOAN AGREEMENT") and as security for its obligations
under the Note, Debtor has agreed, among other things, to grant Secured Party a
security interest in the Collateral (as defined below) on the terms set forth in
this Agreement. An Intercreditor Agreement of even date herewith (the
"INTERCREDITOR AGREEMENT") by and among Debtor, the Secured Party and Caldera
Systems, Inc. ("CALDERA") sets forth the parties' agreement with respect to the
relative priorities of the Liens of Secured Party and Caldera.

         NOW, THEREFORE, in consideration of the foregoing recitals, and for
other good and valuable consideration, the receipt and sufficiency of which are
hereby acknowledged, the parties hereto hereby agree as follows:

         1. DEFINED TERMS. All capitalized terms used in this Agreement that are

to such terms in the Note.

         2. GRANT OF SECURITY INTEREST; COLLATERAL ASSIGNMENT. As collateral
security for the prompt and complete payment and performance when due (whether
at the stated maturity, by acceleration or otherwise) of the Obligations, and
subject to Caldera's rights under the Intercreditor Agreement and Prior Liens
set forth in Exhibit B to this Agreement, Debtor hereby grants to Secured Party
a first priority security interest in all of Debtor's assets, which assets are
collectively referred to herein as the "COLLATERAL" and include, without
limitation:

                  (a) General Intangibles. All of Debtor's General Intangibles,
now existing or hereafter arising or acquired, together with the proceeds there

letters of credit, guarantee claims, security interests, or other security held
by Debtor to secure any "Accounts" (as hereinafter defined).

                  (b) Accounts (including Accounts Receivable). All of Debtor's
Accounts, whether now existing or hereafter arising or acquired, together with
the proceeds there from. As used herein, the term "ACCOUNTS" means any right of
Debtor to receive payment from another person or entity, including payment for
goods sold or leased, or for services rendered, no matter how evidenced or
arising, and regardless of whether yet earned by performance. It includes, but
is not limited to, accounts, accounts receivable, contract rights, contracts
receivable, purchase orders, notes, drafts, acceptances, all rights to payment
earned or unearned under a charter or other contract involving the use or hire
of a vessel and all rights incident to the charter or contract, and other forms
of obligations and receivables.

                  (c) Inventory. All of Debtor's Inventory, whether now owned or
hereafter acquired, together with the products and proceeds there from and all
packaging, manuals, and instructions related thereto. As used herein, the term
"INVENTORY" means all goods, merchandise, and personal property held for sale or
lease or furnished or to be furnished under contracts of service, and all raw
materials, work in process, or materials used or consumed in Debtor's business,
wherever located and whether in the possession of Debtor, a warehouseman, a
bailee, or any other person.

                  (d) Equipment. All of Debtor's Equipment, now owned or
hereafter acquired, together with the products and proceeds there from, and all
substitutes and replacements therefor. As used herein, the term "EQUIPMENT"

in Debtor's business, all accessions, attachments, and other additions thereto,
all parts used in connection therewith, all packaging, manuals, and instructions
related thereto, and all leasehold or equitable interests therein.

                  (e) Fixtures. All of Debtor's interest in and to all fixtures
and furnishings, now owned or hereafter acquired, together with the products and
proceeds there from, all substitutes and replacements therefor, all accessories,
attachments, and other additions thereto, all tools, parts, and supplies used in
connection therewith, and all packaging, manuals, and instructions related
thereto, located on or attached to Debtor's business premises located at 425
Encinal, Santa Cruz, California 95061.

                  (f) Chattel Paper, Documents and Instruments. All of Debtor's
right, title, and interest in any chattel paper, documents, or instruments, now
owned or hereafter acquired or arising, or now or hereafter coming into the
possession, control, or custody of either Debtor or Secured Party, together with
all proceeds there from. The terms "chattel paper," "documents," and
"instruments" shall have those meanings ascribed to them in the Utah Uniform
Commercial Code.

                  (g) Excluded Assets. Notwithstanding the foregoing, in no
event shall Collateral include, and Secured Party shall not be deemed to have an
interest in, any of Debtor's

                                       2
<PAGE>   3

right, title or interest (a) in any Intellectual Property if the grant of such
interest shall constitute or result in the abandonment, invalidation or
rendering unenforceable any right, title or interest of Debtor therein, (b) in
any license, contract or agreement to which Debtor is a party or any of its
rights or interests thereunder to the extent, but only to the extent, that such
a grant would, under the terms of such license, contract or agreement, or
otherwise, result in a breach or termination of the terms or, constitute a
default under or termination of, any such license, agreement or contract (other
than to the extent that any such term would be rendered ineffective pursuant to
the Uniform Commercial Code of any relevant jurisdiction, and any other
applicable law or principles of equity); provided that immediately upon the
ineffectiveness, lapse or termination of any such provision, the Collateral
shall include, and Debtor shall be deemed to have granted a security interest
in, all such rights and interests as if such provision had never been in effect;
(c) in connection with the Agreement and Plan of Reorganization dated July 31,
2000 (the "REORGANIZATION AGREEMENT"), whether issued to Debtor by Caldera or
Caldera International, Inc., (i) the 982,500 shares of common stock to be used
by Debtor to fulfill its prior warrant obligations, or (ii) the number of
shares, which shall not exceed 2,500,000 shares of common stock to be used in
funding employee stock options for Debtor's employees that will be transferring
to Caldera International, Inc. upon the close of the Reorganization Agreement,
and (d) in any of the outstanding capital stock of a controlled foreign
corporation (as such term is defined in the Internal Revenue Code of 1986, as
amended) in excess of 65% of the voting power of all classes of capital stock of
such controlled foreign corporation entitled to vote.

         3. REPRESENTATIONS AND WARRANTIES. Debtor hereby represents and
warrants to Secured Party that:

                  (a) Title; No Other Liens. Except for (i) the liens granted to
Secured Party pursuant to this Agreement (ii) the Prior Liens, and (iii) the
Permitted Liens, Debtor owns (and, in the case of after-acquired Collateral,
will own at the time it is acquired) all right, title and interest in and to
each item of the Collateral free and clear of any and all liens, claims,
security interests, encumbrances and restrictions of any kind. No security
agreement, financing statement or other public notice with respect to all or any
part of the Collateral is on file or of record in any public office, except such
as may have been filed in favor of Secured Party pursuant to this Agreement and
except such as may have been filed with respect to the Prior Liens or the
Permitted Liens. Debtor has provided Secured Party with copies of all
obligations exceeding $50,000 secured by a lien on any of the Collateral.

                  (b) No Consents. Debtor has all right, power and authority
necessary to grant Secured Party the security interest granted in Section 2
above, without the need for the consent or approval of any third party other
than consents or approvals that have been obtained.

                  (c) Location of Collateral. The Collateral (other than the
Intellectual Property) is located and will at all times be kept at Debtor's
office at the address indicated above, and such other premises owned or leased
by Debtor.

         4. COVENANTS. Debtor covenants and agrees with Secured Party that, from
and after the date of this Agreement until all Obligations are paid in full and
satisfied:

                                       3
<PAGE>   4

                  (a) Further Documentation. Upon Secured Party's written
request and at Debtor's sole expense, Debtor will promptly and duly execute and
deliver such further instruments and documents and take such further action as
Secured Party may reasonably request for the purpose of obtaining, giving notice
of, protecting, preserving and perfecting the security interests granted under
this Agreement, including, without limitation, the filing of any financing or
continuation statements under the Code in effect in any jurisdiction with
respect to the security interests created hereby and the recording of the
security interests granted hereunder in any Intellectual Property with the
appropriate governmental or other authorities in any jurisdiction. Debtor agrees
that a carbon, photographic or other reproduction of this Agreement (or, if
appropriate, any other Security Document) will be sufficient as a financing
statement for filing in any jurisdiction, if permitted by such jurisdiction.

                  (b) Maintenance of Records. Debtor will keep and maintain
complete records of the Collateral as it does in the ordinary course of
business. For Secured Party's further security, Secured Party will have a
security interest in all of the books and records of Debtor pertaining to the
Collateral.

                  (c) No Liens on Collateral. Debtor will not create, incur or
permit to exist, will defend the Collateral against, and will take such other
action as is necessary to remove, any lien, claim, security interest or
encumbrance on or to any of the Collateral, other than the liens granted to
Secured Party under this Agreement and the Prior Liens and Permitted Liens.

                  (d) Limitation on Dispositions of Collateral. Debtor will use
all commercially reasonable efforts to preserve the Collateral without material
impairment while conducting its business in the ordinary course in a manner that
is consistent with Debtor's past business practices. Debtor will not, through
any license, encumbrance, assignment, transfer or disposition of any of the
Collateral, any creation of obligations of Debtor, any issuance of securities,
or any other action, (i) avoid or seek to avoid the observation or performance
of any of the terms to be observed or performed by Debtor under this Agreement,
(ii) materially impair the benefit of this Agreement or the Collateral to
Secured Party, or (iii) materially and adversely affect Secured Party's ability
to operate, or obtain the financial or economic benefit of, the Collateral in
accordance with the terms of this Agreement; provided, however, that Debtor may
(A) enter into Licenses with third parties in the ordinary course of its
business and consistent with its past licensing practice of Intellectual
Property owned or licensed by Debtor, (B) sell or otherwise dispose of worn-out
or obsolete Equipment or Fixtures, and (C) fulfill its obligations under the
Reorganization Agreement. Debtor will at all times in good faith take, and
assist in taking, all such action as may be necessary or appropriate to protect
Secured Party's rights under this Agreement from impairment and to preserve for
Secured Party's benefit the value of the Collateral.

                  (e) No Change in Location, Name, etc. Except upon thirty (30)
days prior written notice to Secured Party, Debtor will not move the Collateral
(other than the Intellectual Property) from the location specified in Section
3(c) above or change Debtor's name, identity or structure to such an extent that
any financing statement or other Security Documents filed by Secured Party would
become misleading.

                                       4
<PAGE>   5

                  (f) Payment of Taxes and Assessments. Debtor will pay prior to
delinquency all taxes and assessments assessed against, levied upon or placed
against the Collateral, other than taxes and assessments being contested in good
faith and by appropriate proceedings, and for which adequate reserves are
maintained on the books of the Debtor in accordance with GAAP.

                  (g) Insurance. Debtor shall maintain insurance with respect to
the Collateral in accordance with the insurance standards and practices adhered
to generally by owners of like collateral.

         5. SECRECY AND ASSIGNMENT OF INTELLECTUAL PROPERTY. Debtor will use
commercially reasonable efforts to ensure that each current and future employee
and contractor hired or engaged by Debtor who receives trade secrets or other
confidential and proprietary information of Debtor and/or who in the course of
his/her employment or engagement with Debtor is involved in any way whatsoever
with the Intellectual Property executes and delivers to Debtor a Debtor's
employee or contractor invention assignment and confidentiality agreement, in
Debtor's customary form, imposing invention and intellectual property rights
assignment obligations and confidentiality obligations on the part of such
employee or contractor to Debtor. Debtor will further take reasonable steps and
procedures to preserve and protect the secrecy of Debtor's trade secrets and
other confidential or proprietary information.

         6. APPOINTMENT OF SECURED PARTY AS ATTORNEY-IN-FACT.

                  (a) Powers. Debtor hereby irrevocably constitutes and appoints
Secured Party, and any agent of Secured Party, with full power of substitution,
as its true and lawful attorney-in-fact with full irrevocable power and
authority in the place and stead of Debtor and in the name of Debtor or in the
name of Secured Party, from time to time in Secured Party's discretion, for the
purpose of carrying out the terms of this Agreement, to take any and all
appropriate actions and to execute any and all documents which may be necessary
or desirable to accomplish the purposes of this Agreement, including (without
limiting the generality of the foregoing) to execute, in connection with any
sale or other disposition of Collateral pursuant to Section 7 hereof, any
endorsements, assignments, bills of sale, licenses or other instruments of
conveyance or transfer with respect to the Collateral. This power of attorney is
a power coupled with an interest and is irrevocable.

                  (b) No Duty on Secured Party's Part. The powers conferred on
Secured Party hereunder are solely to protect Secured Party's interests in the
Collateral and will not impose any duty upon it to exercise any such powers.
Secured Party and its agents will not be responsible to Debtor for any act or
failure to act hereunder, except for Secured Party's own gross negligence or
willful misconduct. It is further agreed and understood between the parties
hereto that such care as Secured Party gives to the safekeeping of its own
property of like kind shall constitute reasonable care of the Collateral when in
Secured Party's possession.

                                       5
<PAGE>   6

         7. SECURED PARTY'S RIGHTS AND REMEDIES; RELEASE.

                  (a) General Remedies. If an Event of Default occurs, then in
addition to exercising any other right or remedies Secured Party may have under
the Note, at law or in equity, or pursuant to the provisions of the Code,
Secured Party may, at its sole option and without demand first made, exercise
any one, some or all of the following rights and remedies:

                      (i) Collect the Collateral and its Proceeds;

                      (ii) Take possession of the Collateral and its Proceeds
wherever such may be found or require Debtor to assemble the Collateral and make
it available to Secured Party at a place designated by Secured Party which is
reasonably convenient to Debtor and Secured Party;

                      (iii) Proceed with the foreclosure of the security
interest in the Collateral or any part thereof granted herein and the sale or
endorsement and collection of the Proceeds of such Collateral in any manner
permitted by law or provided for herein;

                      (iv) Sell, lease, license or otherwise dispose of the
Collateral or any part thereof at public or private sale, with or without having
the Collateral at the place of sale, after giving Debtor ten (10) days prior
written notice of such sale, lease, license or other disposition of Collateral;

                      (v) Institute a suit or other action against Debtor for
recovery on the Note;

                      (vi) Exercise any rights and remedies of a secured party
under the Code; and/or

                      (vii) With respect to any Software, Inventions,
Documentation, Intellectual Property and Licenses, in the exercise of the rights
of a secured party under applicable law with respect thereto, and subject to the
rights of any licensor of any such property not owned by Debtor, use, exercise,
practice, reproduce, perform, display, distribute, create derivative works,
make, have made, sell, license, sublicense, transfer, assign and commercialize.

                  (b) No Election of Remedies. The election by Secured Party of
any right or remedy will not prevent Secured Party from exercising any other
right or remedy against Debtor.

                  (c) Proceeds. If an Event of Default occurs, all proceeds and
payments with respect to the Collateral will be retained by Secured Party (or,
if received by Debtor, will be held in trust and will be delivered by Debtor to
Secured Party in the original form received, endorsed in blank) and held by
Secured Party as part of the Collateral or applied by Secured Party to the
payment of the Obligations.

                  (d) Sale of Collateral. Any item of Collateral may be sold,
leased or licensed or otherwise disposed of for cash or other value at public or
private sale or other disposition and the Proceeds thereof collected by or for
Secured Party. Debtor agrees to promptly execute and deliver, or promptly cause
to be executed and delivered, such instruments, documents,

                                       6
<PAGE>   7

assignments, waivers, certificates and affidavits and supply or cause to be
supplied such further information and take such further action as Secured Party
may require in connection with any such sale or disposition. Secured Party shall
have the right upon any such public sale or sales, and, to the extent permitted
by law, upon any such private sale or sales, to purchase the whole or any part
of the Collateral so sold, free of any right or equity of redemption in Debtor,
which right or equity is hereby waived or released. If any notice of a proposed
sale, lease, license or other disposition of Collateral shall be required by
law, such notice shall be deemed reasonable and proper if given at least ten
(10) days before such sale, lease, license or other disposition. Secured Party
agrees to give Debtor ten (10) days prior written notice of any sale, lease,
license or other disposition of Collateral (or any part thereof) by Secured
Party.

                  (e) Application of Proceeds. The Proceeds of all sales and
collections in respect of the Collateral, the application of which is not
otherwise specifically herein provided for, will be applied as follows:

                      (i) First, to the payment of the costs and expenses of
such sale or sales and collections and the attorneys' fees and out-of-pocket
expenses incurred by Secured Party relating to costs of collection;

                      (ii) Second, any surplus then remaining will be applied
first, to the payment of all unpaid interest accrued under the Note, next to the
payment of unpaid principal under the Note, and next to the satisfaction of any
remaining Obligations; and

                      (iii) Third, any surplus then remaining will be paid to
Debtor.

                  (f) Liability for Deficiency. Debtor will remain liable for
any deficiency if the Proceeds of any sale or other disposition of the
Collateral are insufficient to pay the Obligations and the fees and
disbursements of any attorneys or agents employed by Secured Party to collect
such deficiency.

                  (g) Limitation on Duties Regarding Collateral. Secured Party's
sole duty with respect to the custody, safekeeping and physical preservation of
the Collateral in its possession, under the Code or otherwise, shall be to deal
with it in the same manner as Secured Party deals with similar property for its
own account. Secured Party and its agents will not be liable for failure to
demand, collect or realize upon all or any part of the Collateral or for any
delay in doing so nor will any of them be under any obligation to sell or
otherwise dispose of any Collateral upon the request of Debtor or otherwise.

                  (h) Release. Upon the full and complete payment and
performance when due of the Obligations, upon Debtor's written request and at
Debtor's sole expense, Secured Party will promptly and duly execute and deliver
such further instruments and documents and take such further action as Debtor
may reasonably request for the purpose of releasing or terminating the security
interests granted under this Agreement.

                      (i) This Agreement shall be governed by and construed
under the internal laws of the United States and the State of Utah as applied to
agreements among Utah residents entered into and to be performed entirely within
Utah, without reference to principles of conflict of laws or choice of laws
(except to the extent governed by the UCC).

                      (ii) 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 Utah State Courts in and for
Salt Lake County, Utah or, in the event of federal jurisdiction, the United
States District Court for the Central Division of Utah sitting in Salt Lake
County, Utah, 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.

         9. NO WAIVER. Secured Party will not by any act (except by a written
instrument pursuant to Section 11 hereof), delay, indulgence, omission or
otherwise be deemed to have waived any right or remedy hereunder or to have
acquiesced in any Event of Default or in any breach of any of the terms and
conditions hereof. No failure to exercise, nor any delay in exercising, on the
part of Secured Party, any right, power or privilege hereunder will operate as a
waiver thereof. No single or partial exercise of any right, power or privilege
hereunder will preclude any other or further exercise thereof or the exercise of
any other right, power or privilege. A waiver by Secured Party of any right or
remedy hereunder on any one occasion shall not be construed as a bar to any
right or remedy which Secured Party would otherwise have on any future occasion.
The rights and remedies of Secured Party herein provided are cumulative, may be
exercised singly or concurrently and are not exclusive of any other rights or
remedies provided by law.

         10. SUCCESSORS AND ASSIGNS. The terms and conditions of this Agreement
shall inure to the benefit of and be binding upon the successors and permitted
assigns of the parties; provided, however, that Debtor may not assign or
delegate any of its rights or obligations hereunder without Secured Party's
prior written consent, and any assignment or delegation without such consent
shall be void. Nothing herein shall be interpreted to prevent, limit or
otherwise restrain Debtor's grant of licenses to customers and other third
parties in the ordinary course of its business.

         11. AMENDMENTS AND WAIVERS. Any term of this Agreement may be amended
and the observance of any term of this Agreement may be waived (either generally
or in a particular instance and either retroactively or prospectively), only
with the written consent of both Debtor and Secured Party.

         12. RIGHTS AND REMEDIES CUMULATIVE. The rights and remedies herein
provided will be cumulative and not exclusive of any other rights or remedies
provided by law or otherwise.

         13. 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

                                       8
<PAGE>   9

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 extent possible, the
economic, business and other purposes of the void or unenforceable provision.
