	Reference:	  	a) Telecon between [***] and [***] on 26 August 2009

 Dear
Mr. [***]: 
 During the Reference a) telecom, the following terms for the TerreStar-2 Restart were agreed upon: 

 

	 	1.	The price for the Restart will be $23.986M. This price is based upon not having to perform more than one off-site thermal vacuum test for other SS/L spacecraft. The
payment schedule for the above-stated amount will be provided in a subsequent letter. 

  

	 	2.	As date for the availability of the SS/L thermal vacuum testing facility for TS-2 is not known at this time, the target “ready to ship” date is estimated to
be in the fourth quarter of 2011. There will be no liquidated damages associated with the “ready to ship” date. 

  

	 	3.	The above price does not include the price for the replacement batteries. The price for the batteries will be determined upon the establishment of the approximate ship
date of the spacecraft. 

  

	 	4.	Receipt of the payment of Milestone T2-15, [***], in the amount of [***] is to be wired to SS/L’s account as soon as possible but no later than 3 weeks from the
date of this agreement. 

 Please indicate your concurrence with these terms below. Should you have questions on this matter,
please contact [***] on [***] or [***] on [***] (fax: [***]).
