Subject: QUOTATION - D-2500 and D-Lite

Dear Mr. Eisenberg,

Delphi Corporation is extremely excited about the opportunity you have brought
to us. We believe the Stellar low cost 2-way data communication system will
allow many new markets to afford asset-tracking capabilities on their products.

The pricing is volume based from SOP thru Jan. 1, 2007 with the exception that
the CY2007 pricing will become effective as soon as new, custom integrated
circuit design is available and validated, but no later than Jan. 1, 2007. If
production volumes exceed 220,000 units of D-2500 or 120,000 units of D-Lite
prior to Jan. 1, 2007, a new price can be negotiated.

Non-Recurring Engineering Fee (NRE): $[***]

          The pricing in CY2007 and CY2008 will require Delphi E & S to source a
          custom integrated circuit. Delphi E & S is willing to discuss a
          payment schedule that will defer initial payment of the fee to Jan. 1,
          2005. In case of cancellation of program by Stellar, Stellar will be
          responsible for 50% of Delphi's investment up to the date of
          cancellation.

Timing:

          Delphi E & S continues to commit to a 1st quarter Start of Production
          (SOP) date, March 31, 2005 at the latest. Delphi E & S will continue
          to make efforts to have the earliest SOP feasible.

<PAGE>

Delphi Penalty for Missing SOP:

Delphi is willing to accept a penalty clause to this agreement, not to exceed
$[***] per month. We would request that this clause can be renegotiated if,
during the upcoming requirements definition workshop, a major, unanticipated
requirement is exposed that could significantly affect our SOP commitment.

Beta Units:

          Delphi E & S shall deliver up to 200 D-2500 and 100 D-Lite for testing
          and installation no later than Dec. 1, 2004. Stellar understands that
          these parts are unvalidated and no claims can be submitted to Delphi E
          & S concerning functionality. The price of these Beta units will be 2X
          1st year production pricing.

This quote is valid for a period of thirty (30) days from the date of this
letter. Please notify me in writing regarding your acceptance and intent to
source these parts.

Delphi Delco's Terms and Conditions of Sale are attached and considered as part
of this quote.

If you have any questions, please don't hesitate to contact me at the number
below.

Thank you for this business opportunity!

option shall be entitled to terminate this agreement. In such event, OHB shall
be entitled to be compensated in accordance with the provisions of Article
10.2(a)(i),(ii), (iii) and (v) infra.

consultation shall include identification/qualifications of the replacement and
a transition plan. OHB shall take considerable effort to replace Key Personnel
with personnel of substantially equal qualifications and ability. In the event
of a dispute, ORBCOMM shall communicate the concern to OHB's senior management
to negotiate a mutually agreed upon alternative. Notwithstanding its role in
reviewing Key personnel adjustments, ORBCOMM shall have no supervisory control
over Key Personnel work, and nothing in this Section 12.7 shall relieve OHB of
any of its obligations under this Agreement, or of its responsibility for any
acts or omissions of its personnel. To the extent that the Key Personnel
voluntarily resign, ORBCOMM shall be consulted in the selection of the
replacement personnel but shall not have the right to approve such replacement
personnel.

terminated orally. No claimed modification, termination or waiver of any of its
