Dear
Darl:

This
letter confirms the engagement of Morgan Keegan & Company, Inc. ("Morgan Keegan") to act as exclusive financial advisor to Caldera International, Inc.
("Caldera" or the "Company") to assist the Company in its analysis, consideration and, if appropriate, execution of various financial and strategic alternatives available to it, and such other matters
to which you and we may agree during the course of our engagement. Such financial alternatives and other matters may include assisting the Company in securing additional equity and/or debt capital;
and assisting the Company in its analysis and consideration of the financial aspects of certain potential strategic transactions, including, but not limited to, mergers, acquisitions,
spin-offs, joint ventures, minority investments, negotiated purchases, or other similar transactions (individually, the "Transaction" and collectively, the "Transactions").

As
exclusive financial advisor to the Company, Morgan Keegan will perform the following functions:



In
order to coordinate our efforts with respect to a possible Transaction, during the period of our engagement hereunder, if the Company or its management receives an inquiry regarding a
Transaction, the Company or such persons will promptly advise Morgan Keegan of such inquiry. All contact with third parties by Morgan Keegan must be approved by the Company.

1.     In
consideration for the services rendered by Morgan Keegan hereunder, the Company shall pay Morgan Keegan:







The
"Transaction Consideration" for purposes of calculating a Transaction Fee shall mean the gross value of all cash, securities and other property paid directly or indirectly by an acquiror to a
seller or sellers in connection with a Transaction. A seller may include the Company, an affiliate of the

Company
or stockholders of the Company. The value of any securities (whether debt or equity) or other property delivered as consideration in any Transaction shall be determined as follows:
(i) the value of securities that are freely tradeable in an established public market will be determined on the basis of the average closing market price on the last five trading days
immediately prior to the closing of the Transaction and (ii) the value of securities that are not freely tradeable or have no established public market and the value of consideration that
consists of other property, shall be the fair market value thereof, as reasonably determined by the Company and Morgan Keegan. Transaction Consideration also shall be deemed to include the aggregate
principal amount of all indebtedness assumed or acquired, directly or indirectly, by the acquiring party or any of its affiliates in a Transaction or retired, defeased or otherwise cancelled in
connection with the Transaction and the present value of any agreements not to compete or consulting agreements.

Amounts
paid into escrow and contingent payments in connection with any Transaction will be included as part of the Transaction Consideration. Transaction Fees on amounts paid into
escrow shall be payable upon the release of such amounts paid into such escrow. If any portion of the consideration in connection with any Transaction is payable in the future on the basis of
occurrence of certain future events, the portion of the Transaction Fee relating to such contingent payments shall be payable at the time the actual consideration is paid.

2.     The
Company will advise Morgan Keegan of its intention to make any offers or sales of Securities during the term of this agreement. As used herein, the terms "offer" and
"sale" have the meanings specified in Section 2(3) of the Securities Act of 1933, as amended (the "Act").

3.     The
Company and Morgan Keegan agree that:

4.     If,
in connection with the services or matters that are the subject of this Agreement, Morgan Keegan or any controlling person, affiliate, director, officer, employee or
agent of Morgan Keegan (Morgan Keegan and each such other person referred to as an "Indemnified Person") becomes involved in any capacity in any lawsuit, claim or other proceeding for which indemnity
may be sought pursuant to Section 4 of this Agreement, the Company shall immediately reimburse such Indemnified Person for any and all legal or other expenses reasonably incurred by such
Indemnified Person in connection with investigating, preparing to defend or defending such lawsuit, claim or other proceeding. The Company also agrees to indemnify each Indemnified Person from, and
hold it harmless against, any and all losses, claims, damages, liabilities or expenses to which such Indemnified Person may become subject arising in any manner out of or in connection with the
services or matters which are the subject of this Agreement; provided, however, that the Company shall not be liable under this Section 4 in respect of any loss, claim, damage, liability or
expense to the extent that it is finally judicially determined by a court of competent jurisdiction that such loss, claim, damage or liability resulted directly from the gross negligence or willful
misconduct of Morgan Keegan in the performance of its services hereunder.

The
Company agrees that the indemnification and reimbursement commitments set forth in this Section 4: (i) shall apply whether or not any Indemnified Person is a formal
party to any such lawsuit, claim or other proceeding and (ii) are in addition to any liability that the Company may otherwise have to any Indemnified Person. The Company agrees that, unless a
final judicial determination is made to the effect specified in the proviso in the last sentence of the preceding paragraph, any settlement of a
lawsuit, claim or other proceeding against the Company arising out of the transactions contemplated by this Agreement which is entered into by the Company shall include a release from the party
bringing such lawsuit, claim or other proceeding of each Indemnified Person, which release shall be reasonably satisfactory to Morgan Keegan. The Company further agrees that no Indemnified Person
shall have any liability (whether direct or indirect, in contract, tort or otherwise) to the Company in connection with Morgan Keegan's engagement hereunder, except for such losses, claims, damages or
liabilities incurred by the Company that are finally judicially determined by a court of competent jurisdiction to have resulted directly from the gross negligence or willful misconduct of such
Indemnified Person.

The
Company and Morgan Keegan agree that if such indemnification or reimbursement sought pursuant to this Section 4 is finally judicially determined by a court of competent
jurisdiction to be unavailable, then, whether or not Morgan Keegan is the Indemnified Person, the Company and Morgan Keegan shall contribute to the losses, claims, damages, liabilities and expenses
for which such indemnification or reimbursement is held unavailable (i) in such proportion as is appropriate to reflect the relative benefits to the Company, on one hand, and Morgan Keegan on
the other, in connection with the transactions to which such indemnification or reimbursement relates, or (ii) if the allocation provided by clause (i) above is not permitted by
applicable law, in such proportion as appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative faults of the Company, on the one hand, and Morgan
Keegan on the other, as well as any other equitable considerations; provided, however, that in no event shall the amount to be so contributed by Morgan Keegan exceed the amount of the cash fees
actually received by Morgan Keegan hereunder.

5.     The
term of Morgan Keegan's appointment and authorization hereunder shall extend from the date hereof through February 15, 2003, or such other date as may be
mutually agreed by the Company and Morgan Keegan, and shall be automatically renewed for successive monthly periods until terminated in writing by either the Company or Morgan Keegan. The provisions
of Sections 1, 2, 3, 4, 6, 8, 9, 10 and this Section 5 shall survive any termination of this Agreement. During the term of this Agreement, Morgan Keegan shall provide, on a monthly
basis, the Company with a list of all potential investors, lenders and merger and acquisition candidates ("The Active Candidate List") that Morgan Keegan contacted on behalf of the Company in its
capacity as exclusive financial advisor and with whom the Company had substantive, meaningful discussions. If the Company completes a Transaction with any entity on "The Active Candidate List" within
twelve (12) months of the termination of this engagement, the Company shall be responsible for the payment of the fees under Section 1 of this Agreement.

6.     Morgan
Keegan is a full service securities firm and as such may from time to time affect transactions, for its own account or the account of customers, and hold positions
in securities or options on securities of the Company and other companies which may be the subject of the engagement contemplated by this Agreement.

7.     All
opinions and advice provided to the Company in connection with this engagement are intended solely for the benefit and use of the Company in connection with the
matters described in this Agreement, and accordingly such advice shall not be relied upon by any person or entity other than the Company. The Company will not make any other use of any such opinions
or advice. In addition, none of (i) the name of Morgan Keegan, (ii) any advice rendered by Morgan Keegan to the Company, or (iii) any communication from Morgan Keegan pursuant to
this Agreement will be quoted or referred to in any report, document, release or other communication prepared, issued or transmitted by the Company, or any person controlled by the Company, without
Morgan Keegan's prior written consent, which consent will not be unreasonably withheld.

8.     In
the event of consummation of any transaction, Morgan Keegan shall have the right to place advertisements in financial and other newspapers and journals at its own
expense describing its services to the Company hereunder, provided that Morgan Keegan will submit a copy of any such advertisements to the Company for its approval, which approval shall not be
unreasonably withheld.

9.     The
invalidity or unenforceability of any provision of this Agreement shall not affect the validity or enforceability of any other provisions of this Agreement, which
shall remain in full force and effect.

10.   This
Agreement may not be amended or modified except in writing signed by each of the parties hereto and shall be governed by and construed in accordance with the laws
of the State of Utah. Each of the parties hereto expressly waives all right to trial by jury in any action or proceeding arising out of this Agreement. This Agreement incorporates the entire
understanding of the parties with respect to the subject matter hereof and supersedes all previous agreements should they exist with respect thereto and shall be binding upon and inure to the benefit
of the Company, Morgan Keegan, and the other Indemnified Persons and their respective successors, assigns, heirs and personal representatives.
