Dear Xxxxx:
Reference is made to the Amended and Restated Registration Rights Agreement
dated as of March 31, 1998 (the "Registration Rights Agreement") among American
Mobile Satellite Corporation ("American Mobile"), Xxxxxx Electronics Corporation
("Xxxxxx"), Singapore Telecommunications, Ltd. ("SingTel") and Baron Capital
Partners, L.P. (collectively, the "Guarantors"). Capitalized terms used herein
without definition shall have the respective meanings set forth in the
Registration Rights Agreement.
In consideration of Xxxxxx' agreement with American Mobile not to exercise its
rights to "piggyback" on the Registration Statement on Form S-3 anticipated to
become effective March 31, 1999, American Mobile agrees with Xxxxxx to amend the
Registration Rights Agreement as follows:
1. To extend the expiration date for exercise of the demand registration
rights in Section 2.1(a) by two years, i.e. from March 31, 2005 to
March 31, 2007.
2. To clarify and confirm that the rights provided in the Registration
Rights Agreement are assignable by the Guarantors provided such
assignee agrees to become a party to the Registration Rights Agreement.

3. To provide for one additional Demand Registration that may be exercised
only by Xxxxxx or its assignee. This additional Demand Registration
Right may be exercised only after the two Demand Registration Rights
presently contemplated under the Registration Rights Agreement has been
exercised or if the Guarantors other than Xxxxxx (or assignees thereof)
no longer own any Registrable Securities. If this additional demand
registration right is exercised, the Guarantors other than Xxxxxx (or
assignees thereof) will have piggyback registration rights for any
Registrable Securities they own in accordance with Section 2.2 of the
Registration Rights Agreement.
Very truly yours,
AMERICAN MOBILE SATELLITE CORPORATION
