2.          RE-DOMICILE REORGANIZATION

2.1        Pursuant to Section 2.18 of the Credit Agreement, the Borrower hereby confirms to the Administrative Agent that:

(a)         the Re-Domicile Date will be January 1, 2019;

(b)         the US Parent will become the Borrower under each Credit Facility, other than the Operating Facility, on January 1, 2019;

(c)         the Re-Domicile Reorganization will be implemented in accordance with the Re-Domicile Step Plan; and

(d)         the Re-Domicile Reorganization will result in the Borrower becoming a disregarded subsidiary of US Parent, and will result in the Borrower’s foreign subsidiaries becoming controlled foreign corporations for U.S. federal income tax purposes, which will have different future tax consequences than the Borrower’s existing corporate structure. In addition, following the Re- Domicile Reorganization, distributions from the Borrower to the US Parent that exceed the paid up capital of the Borrower will be subject to a 5% Canadian withholding tax. In order to minimize future Canadian taxes, the steps in the Re-Domicile Step Plan include an out-from-under transaction for Maxar Technologies Holdings, Inc. (“Maxar Holdings (US)”), as described in step 20B of the Re-Domicile Step Plan (the “Out-from-Under Transaction”), which is intended, in part, to prevent future distributions on, and appreciation of, Maxar Holdings (US) shares being subjected to additional Canadian income and withholding taxes. The consummation of the steps in the Re-Domicile Step Plan (including the Out-from-Under Transaction) is not expected to trigger material adverse tax consequences for the Borrower and its Subsidiaries, except for the potential reduction of Canadian tax losses available to them. While the amount of the reduction in such Canadian tax losses will depend upon factors that will not be known until the Re-Domicile Reorganization is completed, based on current valuation estimates, the Borrower believes the Out-from-Under Transaction will result in the reduction of the Borrower’s Canadian capital loss carryforwards of approximately C$217 million. In order to accomplish the Out-from-Under Transaction without incurring any material current Canadian withholding taxes, the Re-Domicile Step Plan provides for the US Parent to issue the Borrower a promissory note that will accrue interest at a rate expected to be approximately 5.45%. Such promissory note will have a principal amount determined by reference to the final valuation of Maxar Holdings (US), such valuation to be determined as soon as reasonably practicable, and will be subject to reduction shortly following the Re-Domicile Reorganization when the paid up capital of the Borrower will be determined. Accordingly, the principal amount of the promissory note that will remain outstanding after the anticipated reduction will not be known until after the Re-Domicile Reorganization and the valuation of Maxar Holdings (US) is completed. However, based on the Borrower’s stock price at November 29th, 2018 and current valuation estimates for Maxar Holdings (US), the principal amount of the promissory note after the anticipated reduction is expected to be between C$0 million and C$970 million. The accrued interest on such promissory note will be subject to

Canadian income taxes, though such taxes are expected to be initially offset by the Borrower’s remaining Canadian tax loss carryforwards. While the Borrower does not expect any other adverse tax consequences to arise in connection with the Re-Domicile Reorganization, it cannot guarantee that other adverse tax consequences will not arise in connection with the Re-Domicile Reorganization.

3.          RE-TRANCHING ELECTION

3.1        Pursuant to Section 2.19 of the Credit Agreement, the Borrower hereby confirms to the Administrative Agent that:

(a)         effective as of January 1, 2019, the Borrower elects to make a Re-Tranching Election and segregate the Operating Facility as the Cdn. Tranche;

(b)         immediately upon such election, the borrower for the Cdn. Tranche (which is being renamed as the Cdn. Borrower) will be the Cdn. Borrower; and

(c)         the Operating Lender for the Cdn. Tranche (which is being renamed the Cdn. Lender) will continue to be Royal Bank and it will continue to use its current Cdn. Lending Office and current US Lending Office as its booking points.
