PAYMENT INFORMATION: The awardee organization will receive information and forms
from the Payment Management System of the Department of Health and Human
Services regarding requests for cash, manners of payment, and associated
reporting requirements. Payment may be made on a cost-reimbursement or advance

Normally, the awardee organization retains the principal worldwide patent rights

Code of Federal Regulations Part 401, the Government receives a royalty-free
license for its use, reserves the right to require the patent holder to license
others in certain circumstances, and requires that anyone exclusively licensed
to sell the invention in the United States must normally manufacture it
substantially in the United States. To the extent authorized by Title 35 United
States Code Section 205, the Government will not make public any information
disclosing a Government-supported invention for a 4-year period to allow the
awardee organization a reasonable time to file a patent application, nor will
the Government release any information that is part of that application.

When purchasing equipment or products under this SBIR award, the grantee shall
use only American-made items whenever possible.

The above referenced grant is scheduled to expire on 01/31/2001. Unless an

submitted within 90 days of the expiration of the grant. Grant closeout
documents consist of a Financial Status Report (0MB 269), Final Invention
Statement (HHS 568) and a Final Progress Report.

The Final Progress Report may be typed on plain white paper and should include,
at a minimum, a summary statement of progress toward the achievement of the
originally stated aims, a list of results (positive and/or negative) considered
significant, and a list of publications resulting from the project as well as
plans for further publications. An original and one copy are required.
