Westminster, Maryland 21157

Dear Jim:

This letter sets forth certain agreements between you (“Guarantor”) and Avatech Solutions, Inc. and Avatech Solutions Subsidiary, Inc. (together, “Avatech”).

On October 28, 2004, Avatech secured a $700,000 line of credit (the “Line”) from K Bank (“Bank”) based on your personal guaranty (“Guaranty”) of the Line. The Line matures, and is due and payable, on the date the Guaranty terminates, currently February 15, 2005. In exchange for your agreement to extend the Guaranty so that it will remain effective until October 27, 2005 (the “Termination Date”), the Company agrees to pay to you a Guaranty commitment fee consisting of cash payments and three year warrants to purchase Avatech common stock, all as follows:

1. Avatech shall pay to you, on or before December 31, 2004, the sum of $28,000 (the “Cash Fee”). The Cash Fee shall be payable notwithstanding any pre-payment or discharge of the Line, and earlier termination of the Guaranty as a result thereof, prior to the Termination Date.

2. Avatech shall immediately issue to you a warrant to purchase 100,000 shares of Avatech common stock. The warrant shall have a term of three years from the issue date, shall have an exercise price equal to the closing price of Avatech’s common stock on today’s date, and shall be exercisable during its term notwithstanding any pre-payment or discharge of the Line, and earlier termination of the Guaranty as a result thereof, prior to the Termination Date.

3. You agree to execute and deliver to Bank a new guaranty that will be effective until October 27, 2005.

If you agree to the foregoing, please execute this letter agreement in the space indicated below and return a fully executed copy to Avatech.

Sincerely,

/s/ Christopher D. Olander
