Geoworks Operating System Provides the Foundation for Nokia's Newest Communicator

New Nokia 9110 Communicator Maximizes Geoworks' Innovative GEOS Operating System

HANOVER, Germany, CeBIT (March 18, 1998) - Continuing its role as a leading provider of software solutions for the mobile communications market, Geoworks Corporation (NASDAQ: GWRX) announced that its graphical, communications-centric GEOS operating system provides the foundation for the new Nokia 9110 Communicator for GSM 900 markets, introduced today at CeBIT '98.

As a follow up to the acclaimed Nokia 9000 Communicator, the new product marks another major milestone for both Geoworks and Nokia. Nokia's innovations in product design and functionality are joined with enhancements to Geoworks' GEOS operating system, creating a new class of full-featured communications devices.

"Nokia's innovative product is an excellent example of how the flexible capabilities of GEOS can be leveraged to create a wide variety of compelling products in the smart phone market," said David Thatcher, Geoworks' president. "Nokia's unveiling of the 9110 Communicator is another major milestone for Geoworks, because it reflects the first of the next generation smart communicator which follows the trend of other consumer products - smaller, lighter, more powerful and providing longer battery life."

Because GEOS is able to provide a high level of functionality to mobile communications devices, the Nokia 9110 Communicator is able to fully utilize the power of GEOS. With its patented, flexible user interface, GEOS enabled Nokia to create an easy-to-use product that features custom pop-up menus and zoom-in screens for more convenient access to applications and extended functions. The interface provides a uniform look and feel between the device's communications capabilities and its built-in features and applications.

Flexible Interface Enables Range of Products
Geoworks has established its leadership position in the smart phone and communicator market through its relationships with leading handset manufacturers. Nokia has been joined by Toshiba and Mitsubishi as licensees of Geoworks' open operating system, which has been customized by these OEMs to meet the specialized needs of different segments of the market.

Geoworks' GEOS operating system utilizes a patented, graphical flexible user interface, which can enable a wide range of communications products and be customized by OEMs to create strong brand identity in both hardware and software. This allows competing manufacturers to develop highly differentiated product lines, tailored for specific markets, using the same open operating system.

With the Nokia 9110, Geoworks and Nokia are utilizing the world's smallest removable solid state memory solution for telecommunications products. This is one of the first products to feature the new Siemens/SanDisk MultiMediaCard (MMC) technology, which allows users to easily add and remove memory cards. GEOS's use of MMC also makes it easy for other companies to create add-on, after-market products for the Nokia 9110 Communicator, including plug-in phone books, dictionaries, contact lists and other reference tools.
