("Novatrix") pursuant to which the Registrant has agreed to sell substantially all of its assets to Novatrix (the "Asset Purchase Agreement"). The aggregate purchase price for the sale of the assets is $4,000,000, half of which is to be paid at the closing and the remaining half of which is to be paid upon the earlier to occur of March 1, 2008 or the date on which the Registrant receives 510(k) clearance from the U.S. Food & Drug Administration for its ROBODOC Surgical Assist System. Consummation of the transaction is subject to approval of the Registrant's stockholders as well as other customary closing conditions. Also on August 4, 2006, the Registrant and Novatrix entered into a Loan Agreement and Secured Promissory Note (the "Loan Agreement") pursuant to which Novatrix has agreed to loan to the Registrant up to $6 million as follows: o $2.7 million upon the execution of the Loan Agreement o $3.3 million in two tranches upon reaching certain milestones The Loan Agreement provides that upon the consummation of the sale of assets contemplated by the Asset Purchase Agreement, Novatrix will convert any outstanding obligations to advance funds to the Registrant into obligations of Novatrix to fund its own working capital in equal amounts for the purpose of developing the ROBODOC and ORTHODOC products. In addition, the Loan Agreement provides that upon the approval by the Registrant's stockholders of the asset sale, all obligations of the Registrant to repay amounts owing under the Loan Agreement shall be extinguished. The Loan Agreement further provides that in the event that approval by the Registrant's stockholders of the asset sale does not occur by June 30, 2007, the Registrant shall grant an exclusive license in the Asian markets of its ROBODOC Surgical Assitant System to Novatrix in exchange for a one-time royalty payment of $100,000. Simultaneously with the execution and delivery of the Asset Purchase Agreement and Loan Agreement, the parties entered into a Security Agreement pursuant to which the Registrant granted a security interest in its assets to Novatrix as security for repayment of the Registrant's obligations under the Loan Agreement. Item 8.01. Other Events. On August 4, 2006, as required by the Loan Agreement, the Registrant reached a settlement with over 80% of its outstanding creditors pursuant to which each such creditor agreed to extinguish all outstanding debts of the Registrant owed thereto in exchange for a payment by the Registrant to each such creditor of 17.6 cents for each dollar owed.
