Dear Colleen,

On behalf of Novell, Inc. (“Novell”), I am pleased to offer you the position of Senior Vice President of Novell, Worldwide Services. In this position, you will be reporting directly to Ron Hovsepian, President and Chief Executive Officer, and your responsibilities will be those commonly associated with the position of Senior Vice President, Worldwide Services. Your expected start date with Novell will be mutually agreed to between you and Ron Hovsepian, but in no event will it be later than December 4th, 2006.

Your base salary will be no less then $14,583.33 per bi-monthly pay period (less applicable tax withholding), which is $350,000 annualized (less applicable tax withholding). In addition to your base salary, you will be eligible to participate in Novell’s Annual Bonus Program. Your bonus will be based on the attainment of certain performance goals, which may be determined based on your individual performance, the performance of your group and/or Novell’s performance. These goals will be established by Novell, and your annualized target bonus will represent a percentage of your annual base salary, which may be up to 60% of your base salary. For Fiscal Year 2007, 50% of your first year bonus will be guaranteed.

You will also receive a one-time sign-on bonus equal to $200,000 (less applicable tax withholding) if you remain employed by Novell for six months. This sign-on bonus will be paid to you in a lump sum cash payment within the first sixty days of your employment; however, if, at any time within the six month period after the date you commence employment with Novell, either Novell terminates your employment for cause or you resign from your position with Novell for any reason, you will be required to immediately repay to Novell the entire amount of this sign-on bonus.

Upon commencement of your employment with Novell, you will be granted a non-qualified stock option to purchase 200,000 shares of Novell common stock under one of Novell’s equity compensation plans. These options will vest 25% one year after your commencement date with an additional 2.0833% to vest on each monthly anniversary thereafter.

In addition to your initial stock option grant and restricted stock units, you will be eligible to participate in Novell’s discretionary Executive Long Term Incentive Equity Plan, which will provide you with the opportunity to receive annual stock option grants to purchase Novell common stock, subject to the approval of Novell’s Compensation Committee.

To facilitate your relocation to Boston from New Jersey, Novell, Inc. will provide you with $150,000 USD. This reimbursement will be made to you upon your move to Boston.
