PRODUCT SUPPLEMENT A

This is Product Supplement A under the Master Supply Agreement entered into by and between TerreStar Corporation and Elektrobit Inc. dated December 1^st, 2009 (“Agreement”). Capitalized terms used herein that are defined in the Agreement, have the meaning set forth therein.

1. PRODUCT

1.1 Product Specifications and Performance Requirements

Product Specifications, Product Structure and performance requirements for this product are as defined in the appropriate documents noted in Table 1 of Exhibit 2 of this Product Supplement A. These documents will be updated over time and will be mutually accepted as the governing documents through the Change Control Process defined in Appendix A of the Agreement.

2. PRICING AND PAYMENT TERMS

2.1 Pricing

Prices for the Product are defined in Exhibit 1 to this Product Supplement A.

Prices are based on the following assumptions:

Notwithstanding price change provisions defined in Section 11.1 of the Agreement, if the volume of Products in the initial order of Products and the first two months of the initial rolling forecast (covering a period of seven months), as defined in Section 8.1 of the Agreement, decreases by more than twenty-five percent (25%) of the volume defined above, EB and TerreStar will mutually agree on a commercially reasonable price increase for the Products.

2.2 Payment Terms

In conjunction with submitting a purchase order to EB for the purchase of Products, TerreStar will make a downpayment to EB equal to [***] percent ([***]%) of the value of the purchase order and EB will invoice TerreStar for the balance due upon delivery to TerreStar. For the sake of clarity, EB is entitled to use the downpayment for the procurement of Materials as and when it chooses. For a particular Product, starting with the purchase order submitted by TerreStar after (i) purchasing a cumulative total of [***] units of such Products or (ii) one year after first shipment of such Product, whichever comes later, the Parties will discuss and negotiate in good faith the possibility of reducing the downpayment percentage in each subsequent month of the Initial Term and any Renewal Terms.

The downpayment set forth above shall be paid by TerreStar within three (3) days of the placement of the respective purchase order.

2.3 Third Party License Fee Reimbursements

In case the license fees for software included in the Products are subject to pre-payment, EB has the right to invoice such license fees to TerreStar in a similar way to End-of-Life Part(s).

In addition, TerreStar acknowledges that the license fees for software included in the Products set by EB’s licensors are based on the volume assumption defined above in Section 2.1 (Pricing). To the extent the actual volume of ordered Products is less than the assumption of [***] units during the first twelve (12) months of manufacturing, and EB is anyhow required to pay license fees towards its licensors based on the [***] unit, TerreStar will reimburse the difference to EB upon EB’s request.

3. LOGISTICS

3.1 Forecasting, Ordering and Lead Time

TerreStar shall provide EB, a good faith, non-binding rolling forecast indicating TerreStar’s monthly Product requirements for a twelve (12) month period that includes the combination of issued purchase orders and monthly forecasts. TerreStar will provide the forecast by the 20th day of each month. TerreStar shall provide the initial forecast in writing to EB separately within five (5) days from the Effective Date of the Agreement. TerreStar will make all forecasts in good faith given market and other information available to TerreStar.

Within five (5) days from the Effective Date of the Agreement, TerreStar shall place an initial binding purchase order, issued in accordance with Section 8 of the Agreement, covering the first two (2) months of the Initial Term. Thereafter TerreStar shall submit by the 20th day of each subsequent month of the Initial Term and any Renewal Terms a binding purchase order for Product(s) issued in accordance with Section 8 of the Agreement.

Except for the first purchase order, EB will be obligated to deliver Products approximately five and half (5.5) months after the date of the purchase order unless otherwise mutually agreed to by the Parties.

4. CHANGES, CANCELLATION, RESPONSIBILITY FOR INVENTORY AND PRODUCTS

4.1 Changes and TerreStar Responsibility for Inventory and Products.

TerreStar may, by written notice to EB, (i) increase the quantity of Products or (ii) reschedule the quantity of Products and their shipment date in any purchase order it has submitted to EB, and which EB has accepted, as provided in the flexibility table below (the “Flexibility Table”):

Maximum Allowable Variance From Original Accepted Purchase Order Quantities/Shipment Dates

Any decrease in quantity is considered a cancellation of those units, unless the decreased quantity is rescheduled for delivery at a later date in accordance with the Flexibility Table. Quantity cancellations are governed by the terms of Section 4.2 below. Any purchase order quantities increased or rescheduled pursuant to this Section 4.1 may not be subsequently increased or rescheduled.

In case of quantity increases, TerreStar will make a downpayment for such increased Product quantities in accordance with Section 2.2 above.

All reschedules to push out delivery dates outside of the Flexibility Table require EB’s prior written approval, which, in its sole discretion, may or may not be granted. If TerreStar does not request prior approval from EB for such reschedules, or if TerreStar and EB do not agree in writing to specific terms with respect to any reschedule, then TerreStar will pay EB the Monthly Charges for any such reschedule for any Inventory that were procured by EB and/or its subcontractor to support the original delivery schedule that is not used to manufacture Product pursuant to an accepted purchase order within thirty (30) days of such reschedule. In addition, if EB notifies TerreStar that such Inventory has remained in EB’s and/or its subcontractor’s possession for more than ninety (90) days since such reschedule, then TerreStar agrees to immediately purchase any affected Inventory (except for End of Life Parts already purchased by TerreStar) upon receipt of the notice from EB by paying the Affected Inventory Cost. In addition, any finished Products that have already been manufactured to support the original delivery schedule will be treated as cancelled as provided in Sections 4.2 below.

All reschedules or quantity increases outside of the Flexibility Table require EB’s approval, which, in its sole discretion, may or may not be granted. If EB agrees to accept a reschedule to pull in a delivery date or an increase in quantities in excess of the Flexibility Table and if there are extra costs to meet such reschedule or increase, EB will inform TerreStar for its acceptance and approval in advance.

4.2 Cancellation of Orders and TerreStar Responsibility for Inventory and Products.

TerreStar may not cancel all or any portion of Product quantity of an accepted purchase order without EB’s prior written approval, which, in its sole discretion, may or may not be granted. If TerreStar does not request prior approval, or if TerreStar and EB do not agree in writing to specific terms with respect to any approved cancellation, then TerreStar will pay EB Monthly Charges for any such cancellation, applicable to any Product and/or Inventory procured by EB and/or its subcontractor to support the original delivery schedule. In addition, if EB notifies TerreStar that such Product and/or Inventory have remained in EB’s and/or its subcontractor’s possession for more than thirty (30) days since such cancellation, then TerreStar agrees to immediately purchase from EB such Product and/or Inventory (except for End of Life Parts already purchased by TerreStar) by paying the Affected Inventory Costs. In addition, EB shall calculate the cost or gain of

unwinding any currency hedging contracts entered into by EB to support the cancelled purchase order(s). Should the unwinding result in a loss to EB, TerreStar agrees to cover such loss amount for EB immediately upon receipt of an invoice for such amount. Should the unwinding result in a gain to EB, a credit note will be immediately issued to TerreStar.

If the purchase order for any period is less than the previous forecast supplied for the same period, and the reduction in quantities actually ordered causes EB to incur third party costs for Inventory purchased or ordered by or for EB, to support the forecast (except for End of Life Parts already purchased by TerreStar), TerreStar will reimburse EB for such additional third party costs provided that EB uses its commercially reasonable efforts for a period of thirty (30) days to mitigate such costs by reallocating, selling or otherwise salvaging such Inventory. EB will provide supporting information on such costs as reasonably requested by TerreStar.
