            WHEREAS, Assignor is the owner of the patents, patent applications
and utility models listed on Exhibit A attached hereto, which are either issued
or pending (including the divisionals, continuations, continuations-in-part,

                                  SCHEDULE D TO
                 EXCEPTIONS INDICATED IN SECTION 5. (b) and (f)

1.    See the list of Flex UI licensees listed on Schedule A.

2.    In the Settlement and License Agreement dated December 28th, 2000 with
Openwave Systems, Inc., Seller settled litigation with Openwave and cross
licensed the Flex UI patents along with one other patent then or within eighteen
months thereafter owned by Geoworks to be selected by Openwave by the end of
this eighteen month period. Therefore, the Flex UI patents are and potentially
one additional Patent could be subject to the terms of this agreement.

3.    In the Cross-License Agreement dated September 1, 2000 with
Telefonaktiebolaget LM Ericsson, the Flex UI patents, US patent #5,742,905, US
patent #6,317,781 and US #5,742,668 patent (as a continuation of US '905
patent), were cross licensed to Ericsson and its affiliates and will remain
subject to the terms of this agreement.

4.    In connection with the purchase of the AirBoss business unit from
Telcordia Technologies, Inc., Telcordia assigned several patents to Geoworks,
including US patents #5,742,905 and #5,742,668 patent (as a continuation of US
'905 patent), and Geoworks licensed back the rights to these patents to
Telcordia and its affililates. Therefore, the #905 Patent remains subject to the
terms of this agreement.

5.    In the License Agreement dated October 8, 2001 with GoAmerica Corporation,
the Flex UI patents were licensed to GoAmerica and its affilates along with
another patent of Geoworks. The Flex UI patents will remain subject to this
agreement.

6.    In the conduct of its business, Geoworks sold and licensed various
products that may have incorporated technologies infringing on the Patents to
various persons. Also, in connection with the sale of its legacy assets, i.e.,
the AirBoss, Mobile Server Plus, GEOS and GEOS-SC technologies, Geoworks has
agreed that neither it nor any successor in interest to any of the Patents would
sue such purchaser, its suppliers or customers for any infringement of the
Patents occasioned by the manufacture, use or distribution of such legacy
assets. Therefore, Buyer's ability to sue such persons for infringement would be
limited by such agreements.
