prices between $28.33 to $56.66 per share. The purchase options expire on the
tenth anniversary of the date they are first exercisable. The Peconic Fund
currently only holds the purchase options it acquired in 2000.

     In connection with the sale of common stock and purchase options to
Leucadia National Corporation, ParkerVision issued to Mr. David Cumming, at the
direction of Leucadia 10,590 shares of common stock and a purchase option to
purchase 10,590 shares of common stock. The purchase option is on the same terms
as that issued to Leucadia National Corporation. The shares were transferred
under this prospectus in October 2001 in compliance with Section 5 of the
Securities Act of 1933. In January 2003, Mr. Cumming transferred the purchase
options to family members and a related entity as follows: Cumming Investment

options and Margaret E. Cumming - 3,176 purchase options.

     The agreements for the registration rights granted to the selling
stockholders provide that ParkerVision and the selling stockholders indemnify
each other against certain liabilities, including liabilities under the
Securities Act of 1933. In the opinion of the Securities and Exchange
Commission, indemnification for these claims is against public policy, and
therefore, it is unenforceable.
