 WHEREAS, Assignee desires to acquire by formal, recordable assignment the entire right, title and interest in and to said Patent in the United States and throughout the world. 
 NOW, THEREFORE, in consideration of the mutual covenants and agreements contained herein and other good and valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties agree as follows: 
 1. Assignment of Patent. Assignor sells, assigns,
transfers and conveys to Assignee all of the entire right, title and interest in and to the Patent in the United States and throughout the world. 
 2. Payment to Assignee. In consideration for the assignment of the Patent hereunder, Assignee agrees to pay to Assignor the following: 
 a. A one-time payment of $25,000.00 payable on or before Dec 31, 2001 
 and 







 b. Royalty payments as follows: 
 i. For each sold Device, the greater of 5% of the net after-tax profits relating to the sale of the Device or $5.00 per Device
sold. 
 “Net After-Tax Profits” is defined as the gross proceeds attributable to the sale of the Device, after deducting therefrom
all costs and expenses attributable to development, testing and sale of the Device, all sales, use, occupation or excise taxes, and all income taxes applicable to income generated from the Device. In no event shall any of the Assignee’s
overhead or expenses unrelated to the Device constitute a deduction for purposes of royalty calculation. 
 3. Accounting and Payment
for Royalty. The accounting and payment for the royalty shall be as follows: 
 a. The Net After-Tax Profits shall be
calculated on a quarterly basis, and Assignee shall pay to Assignor the amounts owing from that quarter’s sales no later than the last day of the month following that applicable quarter.

constitute any payment for any consulting or other personal services.

“sale or exchange of a capital asset” from Assignor to Assignee as defined in, and pursuant to, Section 1235 of the Internal Revenue Code of 1986, as amended, entitled “Sale or Exchange of Patents,” and that all payments
made to Assignor hereunder shall be taxed as long-term capital gains. Nothing in this Agreement to the contrary shall imply that the parties intend that all payments to Assignor hereunder shall be for anything other than the transfer of all
substantial rights which Assignor may have in Patent and in the Device. Assignee, however, is making no warranties or representations as to the ultimate taxability of the payments to Assignor hereunder. 
 6. Further Actions. Assignor, upon request and without further compensation, but without expense to Assignor, shall take such actions and
