Re: The SCO Group, Inc. Series A Convertible Preferred Stock (the “Series A Preferred”)

Ladies and Gentlemen:

We are writing with respect to that certain engagement letter (the “Letter Agreement”), dated as of February 26, 2003, by and among The SCO Group, Inc. (the “Company”) and Boies, Schiller & Flexner LLP, Angelo, Barry & Boldt, P.A., Berger Singerman, and successor firms, if any (collectively, the “Firms”) regarding the retention of the Firms by the Company in connection with the matters described more fully in the Letter Agreement.  The Company hereby agrees that, subject to termination as provided below in this paragraph, the Company shall not engage in any transaction or take any action that could result in a claim for a contingency payment (including, without limitation, any settlement of litigation, sale of the Company or investment in the Company, but excluding any contingency payment in connection with licenses, other than licenses entered into in connection with any settlement of litigation or sale of the Company) by any or all of the Firms under the Letter Agreement or any similar provisions in any other agreement between the Company and any of the Firms (including, without limitation, any successor to or amendment or modification of the Letter Agreement) now in effect or entered into after the date hereof without first obtaining the prior written approval of the holders (the “Holders”) of 66 2/3% of the Series A Preferred outstanding prior to the time of such proposed action, provided that such Holders consist of BayStar Capital II, L.P. (or its affiliated funds) and/or Royal Bank Of Canada.  The Company agrees to provide the Holders with adequate prior notice of, and such information as may be reasonably requested by the Holders concerning, any such action. The parties to this letter agreement hereby acknowledge that the rights described in this letter agreement shall be in addition to all the other rights, preferences, privileges, powers and restrictions of the Series A Preferred (as more fully described in the Certificate of Designation, Rights and Preferences of the Series A Preferred (the “Certificate of Designation”)), as well as all other agreements between the Holders and the Company, each of which are hereby ratified and affirmed, and shall remain in full force and effect.  The rights of the Holders and the obligations of the Company set forth in this letter agreement shall terminate automatically if and when the aggregate number of shares of the Company’s common stock issuable upon full conversion of all outstanding shares of Series A Preferred held by the Holders (without giving effect

to any limitations on conversion set forth in the Certificate of Designation, including, without limitation, Article XIV thereof) fails to equal or exceed five percent of the Company’s outstanding shares of common stock as of the date hereof.
