    The effective date of your resignation as a director and officer is August 6, 2007.
The Board will name a new President and CEO immediately and you will work with him to
effect a smooth transition until your departure on September 7, 2007. A smooth transition
will include your complete cooperation with the new President and CEO to facilitate
employee, customer, operationally, regulatory, and other normal course of business
initiatives and continuity until September 7, 2007.2.
    
    As consideration for your years of service to Digital Angel, for your efforts in a
smooth transition as set forth above, and for your promises and agreements in this Letter
Agreement, Digital Angel agrees to pay to you $320,000 over the next 12 months in
accordance with its ordinary payroll practices, less required deductions and withholdings,
and to grant to you restricted common stock with a total value of $430,000. The number of
 shares of restricted stock to be granted shall be determined by dividing $430,000 by the
closing price of Digital Angels common stock at the close of business on August 8, 2007.
The stock will be issued to you on September 7, 2008 and will bear a standard restrictive
legend providing that such stock may not be sold, transferred, pledged, assigned, or
otherwise encumbered or disposed of by you for a period of one year. Although the
substantive terms of the restricted stock grant shall be as set forth in this paragraph,
the final structure of the stock grant will be finalized by mutual agreement between us,
subject to advice you will seek from your financial advisors.
