Jacksonville, Fla -- ParkerVision (Nasdaq: PRKR) today announced an agreement with Texas Instruments (TI) to develop advanced RF solutions that enable enhanced wireless connectivity, while reducing system size, cost, and overall power consumption in the next generation of wireless handsets.

Under the terms of the agreement, the companies will jointly develop interfaces between ParkerVision's next generation RF transceivers based on Direct2Data(TM) (D2D)(TM) technology and TI's digital baseband chipsets. The agreement also provides for Texas Instruments' foundry services for ParkerVision wireless integrated circuits (IC) using TI's advanced semiconductor process technology. D2D is an innovative approach to processing RF signals, designed to enable efficient, high-performance direct conversion radios that eliminate the need for the intermediate frequency (IF) circuitry used in conventional RF designs.

"This collaboration is an important milestone in the development of high- performance RF solutions using ParkerVision's advanced D2D technology," said Jeff Parker, CEO of ParkerVision. "TI is the leading supplier of DSP and analog-based silicon solutions to the wireless industry, and we are very excited about our relationship with the company. We look forward to the successful implementation of D2D-based transceivers which closely interface with TI's programmable DSP-based wireless solutions."

ParkerVision's initial collaboration with TI will focus on chipsets for wireless networking and next generation, digital wireless handsets.

"Next generation RF solutions will require greater system integration, performance and power efficiency in order to support the market's demand for broadband-enabled, wireless data services," said William Krenik, Director of Advanced Architecture, Texas Instruments Wireless Business Unit. "ParkerVision's D2D transceiver technology represents a differentiated approach to delivering direct conversion and Zero IF system architectures for a range of wireless technologies including 2.5 and 3G handsets, Bluetooth and 802.11."

ParkerVision Chief Technical Officer, David F. Sorrells, commented, "ParkerVision believes that the combination of TI's leading-edge manufacturing processes with our advanced D2D radio technology will enable ParkerVision to create RF platforms of the highest quality that will result in unparalleled wireless solutions for the wireless communications marketplace. ParkerVision believes our D2D technology will emerge as a compelling solution for challenging next generation wireless where the benefits of direct conversion must be delivered without the historical compromises." In conjunction with the agreement, TI has purchased 83,451 shares of ParkerVision restricted common stock, at $29.96 per share, which is the average of the daily closing price of ParkerVision common stock for the ten trading days ending March 7, 2001. Also, ParkerVision has granted 41,725 warrants with an exercise price of $29.96 per share, 20,863 warrants with an exercise price of $37.45 per share, and 20,863 warrants with an exercise price of $39.84 per share.
