EXHIBIT 10.21

Mutual Release  between Teleca and Geoworks dated February 1, 2003

Parties

The parties to this Release are

Geoworks Corporation, a Delaware USA corporation, with its principal place of
business as 6550 Vallejo Street, Suite 102, Emeryville, CA 94608, and
Teleca Ltd, a UK registered company with its principal place of business as 634
Wilmslow Road, Didsbury, Manchester M20 3QX, UK

1.    Background

Teleca and Geoworks have signed a non-disclosure agreement dated May 2002 (the
"NDA") prior to Teleca and Geoworks entering discussions on the sale of
Geoworks' UK subsidiary. These discussions concluded in an Agreement to Purchase
Shares dated September 23, 2002 (the September Agreement). As Geoworks was not
able to attain a quorate number of shareholder votes to approve the transaction,
the September Agreement expired. Included in these prior agreements are
confidentiality provisions and mutual non-solicitation clause preventing either
party hiring the staff of the other.

The current situation has resulted in considerable uncertainty for the UK
Geoworks staff. Given the combination of Geoworks unstable financial situation,
protracted uncertainty over shareholder approval of the September Agreement and
known aggressive staff poaching activities by third party companies interested
in the telecoms skills of Geoworks staff, it is likely that the UK staff will
very quickly find alternative employment and the UK business will become
unsustainable.

In an effort to minimize its potential liability to employees, creditors and
customers of the UK operation, Geoworks plans to terminate its UK operations,
This agreement therefore allows Teleca the right to hire the UK employees and
deal with customers on the terms described below.

2. Right to offer employment and hire

Teleca will offer immediate employment to all of the UK employees, and may pay
signing on bonuses to the employees to encourage their transfer in addition to
the sums covered in this agreement. . The parties will use their best efforts to
transition employment coincident with this Release or as soon thereafter as is
practical. By so doing, for all practical purposes, Geoworks Ltd. will be
relieved of substantial contractual and statutory severance liability assuming
general acceptance by employees.

3.    Release

Geoworks will waive all claims against Teleca for breach of the NDA, including
(but not limited to) terms with respect to hiring and soliciting staff, and the
use of confidential information in connection with hiring or soliciting staff.
Geoworks further waives the right to claim compensation (other than set out in
this agreement) that might be due as a result of Teleca soliciting or hiring
Geoworks staff from any other agreements in force (including but not limited to
the September Agreement.), and any implied, unwritten or verbal agreements, or
general duty's and obligations under law. This release applies to staff at
Geoworks and all Geoworks wholly owned subsidiaries. By signing this release,
Geoworks agrees that the payment described in this agreement is full and fair
payment for waiving its accrued rights to date in this matter, and allowing
Teleca to obtain whatever business benefits it may by this release. This release
does not release Teleca from any obligations created by this release, however.

4.    Customers

March 31, 2003 on existing terms by separate agreement with customers or at

Toshiba's business without Geoworks' prior written approval. . In no event will
