COMMITMENTS	NOTE 6 - COMMITMENTS a. Royalty Commitments The Company is obligated to pay royalties to the National Authority for Technological Innovation (“NATI”) on proceeds from the sale of products developed from research and development activities that were funded, partially, by grants from NATI or its predecessor, the Office of the Israeli Innovation Authority (IIA). At the time the grants were received, successful development of the related projects was not assured. In the case of failure of a project that was partly financed as described above, the Company is not obligated to pay any such royalties or repay funding received from NATI or the IIA.
