ELEKTROBIT (EB) CHOSEN BY TERRESTAR NETWORKS INC. AS ITS PARTNER TO
DEVELOP TECHNOLOGY AND REFERENCE DESIGNS FOR SATELLITE-TERRESTRIAL
MOBILE DEVICES

Elektrobit Corporation (EB), September 20, 2007 - Elektrobit Inc.,
subsidiary of Elektrobit Corporation, and TerreStar Networks Inc.
(TerreStar) have entered into an agreement concerning the development
of handset technologies and reference designs for TerreStar's
upcoming satellite-terrestrial all-IP mobile network. The agreement
between the parties comprises the development of two dual-mode
reference smartphones where EB acts as the main integrator and
delivers turn-key product creation services to TerreStar.

The partnership with TerreStar is important for EB as it brings the
opportunity to apply and enhance the company's strong wireless
communications and 3G smartphone capabilities to a new demanding
application area where HSPA and GMR-3G satellite technologies are
combined to one seamless implementation. This is in line with EB's
strategy for entering new markets and broadening the company's
customer base.

The EB billing under this agreement is time and material based and
the total amount of revenues to be generated by this agreement
depends on the progress of the development work. Under the agreement
the aggregate amount of EB's billing during the years 2007, 2008 and
2009 may not, however, exceed 54 million USD. The revenues that are
expected to be generated during the second half of 2007 have already
been anticipated in the guidance given by EB on August 2, 2007. The
main part of the development work is expected to be performed in 2008
and, assuming that the development under the agreement will proceed
favourably, the agreement is expected to generate a significant share
of EB's Mobile Terminal Solutions Business Unit's turnover in 2008.
Correspondingly, TerreStar will be one of EB's most important
customers. TerreStar and EB have agreed that any intellectual
property rights arising from this development work will be mutually
owned by TerreStar and EB, and they may be utilized by each party
through licensing to third parties.

The development work under the agreement includes typical risks
related to R&D activities on new technologies, such as the
availability and maturity of required components. Furthermore, it is
subject to the terms and conditions for termination, which are
customarily applied in the industry, and which provides, for example,
TerreStar a possibility to terminate the agreement with a short
notice by paying a ramp down fee.
