Item 4.01 Changes In Registrant's Certifying Accountant.

On July 13, 2009 the Audit Committee (the "Audit Committee") of the Board of Directors of TerreStar Corporation (the "Company") appointed Ernst & Young to serve as the Company's independent registered public accounting firm and dismissed our former independent registered public accounting firm, Friedman LLP. Ernst & Young was engaged by the Company on July 13, 2009 and the change in auditors became effective on July 13, 2009. Ernst & Young will review our financial statements beginning the fiscal quarter ending June 30, 2009 and will audit our financial statements for the fiscal year ending December 31, 2009.

Friedman LLP's audit reports on the Company's consolidated financial statements and supporting schedules for the past two fiscal years did not contain an adverse opinion or disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope or accounting principles.

During our two most recent fiscal years and through the date of this Current Report on Form 8-K there were no disagreements with Friedman LLP on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure which, if not resolved to Friedman LLP's satisfaction, would have caused them to make reference to the subject matter in connection with their reports on the Company's consolidated financial statements and supporting schedules for such years; and there were no reportable events, as listed in Item 304(a)(1)(v) of Regulation S-K, except that Friedman LLP's reports on the Company's internal controls over financial reporting as of December 31, 2007 and December 31, 2008 contained an adverse opinion on the effectiveness of the Company's internal controls over financial reporting because of a material weakness.

The Company provided Friedman LLP with a copy of the foregoing disclosures. Attached as Exhibit 16.1 is a copy of Friedman LLP's letter stating their agreement with such statements.

During our two most recent fiscal years and through the date of this Current Report on Form 8-K, neither the Company, nor any party on the Company's behalf, consulted Ernst & Young LLP or any other accounting firm with respect to (i) the application of accounting principles to a specified transaction, either completed or proposed, or the type of the audit opinion that might be rendered on our consolidated financial statements, and no written report or oral advice was provided to us that Ernst & Young LLP concluded was an important factor considered by the Company in reaching a decision as to any accounting, auditing or financial reporting issue, or (ii) any other matters or reportable events listed in Items 304 (a)(2)(i) and (ii) of Regulation S-K.
