respect to any portion of Confidential Information which the receiving Party can demonstrate, by contemporaneous written records or other competent proof:

 Specific aspects or details of Confidential Information shall not be deemed to be within the public domain (or published in the public domain) or otherwise subject to an
exclusion in this Section 4.2 merely because the Confidential Information is described or otherwise embraced by more general information in the public domain (or published in the public domain) or in the possession of either Party. Further, any
combination of Confidential Information shall not be considered in the public domain (or published in the public domain) or otherwise subject to an exclusion in this Section 4.2 merely because individual elements of such Confidential

disclosing Party shall first have given notice to the other Party thereof, including to whom any such disclosures are made; and provided further that no Person receiving information pursuant to this subsection shall disclose any Confidential
Information to any Person without the prior written consent of the other Party, unless such disclosure is made in response to a valid order of a court of competent jurisdiction or other supra-national, federal, national, regional, state, provincial

developments and applications. 
 (iii) In the event that TerreStar elects to abandon any TerreStar Intellectual Property, TerreStar may, at
its option, notify Technologies in writing in advance of the due date of any payment or other administrative action that is required to maintain such intellectual property, and may, at its option, grant Technologies or an Affiliate of Technologies

promptly as possibly consistent with its normal business practices. Without limiting the foregoing, each Party’s designated representatives shall meet from time to time and, in any event, whenever reasonably requested by the other Party, to
discuss the Intellectual Property licensed pursuant to this Second Amended and Restated Agreement. Notwithstanding the foregoing, neither Party shall be required to furnish to the other Party any information that such Party receives or has received
from Third Parties, which information such Party may not lawfully disclose or the utilization of which requires the payment of royalties by such Party to Third Parties, except when such utilization is permissible with the payment of an appropriate
royalty by the other Party. Neither Party shall be required to furnish to the other Party any information that such Party develops for, or in cooperation with, Third Parties to the extent that such Party may not lawfully disclose such information to
the other Party.

 6.1 Notice of Infringement;
Cooperation. 
 (a) If either Party suspects or determines that any Intellectual Property of the other Party licensed hereunder is being
infringed, misused, violated or misappropriated by a Third Party’s activities, it shall promptly notify the other Party in writing and provide such other Party with any evidence of such infringement, misuse, violation or misappropriation that
is reasonably available. As between the Parties to this Second Amended and Restated Agreement, the licensor of the Intellectual Property under this Second Amended and Restated Agreement shall have the exclusive right, in its sole discretion, to
enforce the Intellectual Property that it has licensed hereunder and otherwise seek to terminate or remove such actual or suspected infringement, misuse, violation or misappropriation. In the event that the licensor of the Intellectual Property
under this Second Amended and Restated Agreement elects not to so enforce its Intellectual Property or otherwise seek to terminate or remove such infringement, misuse, violation or misappropriation, then the other Party may elect to proceed with
such enforcement or such termination or removal of any such infringement, misuse, violation or misappropriation (as applicable), at its expense and, to the extent possible, in its own name, subject to prior written approval of the licensor of the
Intellectual Property, which approval shall not be unreasonably withheld. The licensor of the Intellectual Property shall reasonably cooperate with the other Party in connection with such activities consented to in writing by the licensor of the
Intellectual Property; provided, however, that any right that may be granted to the other Party to enforce any such Intellectual Property is subject to any enforcement rights granted by the licensor of the Intellectual Property to
other Persons under any and all separate agreements. 
 (b) The Party not enforcing the Intellectual Property shall provide reasonable
assistance to the enforcing Party, including providing access to relevant documents and other evidence, making its employees available at reasonable business hours, and joining the action to the extent reasonably necessary to allow the enforcing
Party to maintain the action, establish jurisdiction or standing, or otherwise seek or recover damages or obtain other relief. 
 (c) Any
amounts recovered pursuant to this Section 6.1, shall be retained by the enforcing Party (after reimbursing the other Party for their reasonable expenses incurred pursuant to Section 6.1(b)). 
 6.2 Infringement of Third Party Intellectual Property. Each Party (the “Accused Party”) shall promptly notify the other Party (the
“Non-Accused Party”) of any pending or threatened claim that (a) such Accused Party is infringing, violating, misappropriating, or misusing the intellectual property rights of a Third Party if such alleged infringement,
violation, misappropriation, or misuse is reasonably likely to have resulted from such Accused Party’s exercise of its rights or performance of its obligations hereunder, or (b) any of the Parties’ Intellectual Property licensed
hereunder, or the Parties’ rights thereto, are wholly or partially invalid, unenforceable, should be shortened in duration or are otherwise compromised in priority or effectiveness. The Non-Accused Party shall have the right to join 

  

 -17- 

 
the suit; provided that within thirty (30) days after receipt of written notice of the claim, the Non-Accused Party shall notify the Accused
Party of its election to join such suit with respect to any pending or threatened claim under clause (a) or (b) of the preceding sentence. If the Non-Accused Party elects to join such suit, then the Parties shall cooperate in the defense
and settlement of any such claim. Such defense and settlement shall be conducted jointly by the Parties and they shall share any resulting expenses on an equal basis. The Accused Party and shall keep the Non-Accused Party reasonably informed of the
status of any suit with respect to any pending or threatened claim as described herein.

Party’s Confidential Information. 
 Specific aspects or details of Confidential Information shall not be deemed to be within the public domain (or

domain) or in the possession of either Party. Further, any combination of Confidential Information shall not be considered in the public domain (or published in the public domain) or otherwise subject to an exclusion in this Section 3.2 merely

notice to the other Party and given the other Party a reasonable opportunity to quash such order and to obtain a protective order requiring that the other Party’s Confidential Information and documents that are the subject of such order be held
in confidence by such court or agency or, if disclosed, be used only for the purposes for which the order was issued; and provided further that if a disclosure order is not quashed, the other Party’s Confidential Information disclosed in
response to such court or governmental order shall be limited to that information which is legally required to be disclosed in response to such court or governmental order (such notice, procedures and requirements set forth in this
Section 3.3(a) shall be referred to as the “Disclosure Requirements”); 
 (b) Made by either Party to a regulatory
authority as required in connection with any filing, application or request for approval; provided, however, that reasonable measures shall be taken to assure confidential treatment of such information;

forth in this Article III; provided, however, that the disclosing Party shall first have given notice to the other Party thereof, including to whom any such disclosures are made; and provided further that no Person receiving
information pursuant to this subsection shall disclose any Confidential Information to any Person without the prior written consent of the other Party, unless such disclosure is made in response to a valid order of a court of competent jurisdiction
or other supra-national, federal, national, regional, state, provincial or local governmental or regulatory body of competent jurisdiction and such Person has complied with the Disclosure Requirements; or

obligations under their respective sublicense agreements, each of whom prior to disclosure must be bound in writing by obligations of confidentiality and non-use at least equivalent in scope to those set forth in this Article III; provided,
however, no sublicensee other than disclosure by a Party to a sublicensee that is an Affiliate shall disclose any Confidential Information to any Person without the prior written consent of the owner of such Confidential Information, unless
such disclosure is made in response to a valid order of a court of competent jurisdiction or other supra-national, federal, national, regional, state, provincial or local governmental or regulatory body of competent jurisdiction and such sublicensee
has complied with the Disclosure Requirements. 
 (e) Public Statements Regarding Agreement. The Parties agree that this Sublicense
Agreement may be disclosed by each of them, consistent with applicable legal requirements, and to existing or potential acquirers or merger candidates, investment bankers, existing or potential investors, venture capital firms or other financial
institutions or investors for purposes of obtaining financing, or for other purposes in connection with their respective businesses. The Parties agree, however, that they may not issue a press release regarding the Agreement without the prior
written approval of the other Party, and that each Party will provide each other a copy for prior approval of any language summarizing or characterizing the Agreement to be included in any public disclosure. The Parties agree it is critical to each
of them and their respective businesses to ensure that the public characterization of this Agreement is both accurate and appropriate, and will use their best efforts to ensure that the obligations hereunder are fully understood and complied with.

 [Signature page to ATC TerreStar Sublicense Agreement]Letter Agreement, dated 026/2007 between Mobile Satellite LP & Mobile Satellite

 Exhibit 10.55 
 February 6, 2007 
 Mr. Robert Power 
 Vice President, Regulatory Matters 
 Mobile Satellite Ventures (Canada) Inc. 
 1601 Telesat Court 
 Ottawa, ON 
 K1B 5P4 
 Dear Bob: 
 This letter agreement (“Agreement”) confirms our agreement relating to the use of the MSV-1 satellite, licensed by the Federal Communications
Commission (“FCC”) to Mobile Satellite Ventures Subsidiary LLC (“MSV”), and the MSV-2 satellite, licensed by Industry Canada to Mobile Satellite Ventures (Canada) Inc. (“MSV
Canada”), as in-orbit spare satellites. MSV and MSV Canada (collectively, the “Parties”) desire to operate their respective satellites in conjunction with one another to provide hybrid
satellite/terrestrial service to users throughout North America. To the extent one of these satellites should suffer a launch or in-orbit failure, the Parties desire to use the surviving satellite to continue service to customers. Now, therefore, in
consideration of the promises and the mutual representations, undertakings and agreements hereinafter set forth, the Parties hereby agree as follows: 
 1. Failure of MSV-1 Satellite. To the extent that the MSV-1 satellite should suffer a launch or in-orbit failure, whether partial or complete, MSV Canada hereby agrees to make available to MSV sufficient
capacity on the MSV-2 satellite, to the extent necessary to provide continuing service to the customers of the Parties. MSV Canada will ensure that sufficient satellite capacity remains available on MSV-2 satellite at all times to allow for all
satellite traffic formerly handled by MSV-1 satellite to be transitioned to MSV-2 satellite as contemplated herein. 
 2. Failure of MSV-2
Satellite. To the extent that the MSV-2 satellite should suffer a launch or in-orbit failure, whether partial or complete, MSV hereby agrees to make available to MSV Canada sufficient capacity on MSV-1 satellite to the extent necessary to
provide continuing service to the customers of the Parties. MSV will ensure that sufficient satellite capacity remains available on MSV-1 satellite at all times to allow for all satellite traffic formerly handled by MSV-2 satellite to be
transitioned to MSV-1 satellite as contemplated herein. 
 3. Use of L band Frequencies. Nothing in this Agreement shall be construed
to alter the agreement between MSV and MSV Canada set forth in the letter dated October 16, 2003 (attached hereto as Exhibit A) pertaining to the use of spectrum coordinated by either Canada or the United States for use on a satellite that has
been licensed by one of these Administrations. 

 4. Mexico City Memorandum of Understanding. Further, it is the mutual understanding of the Parties
that: 
 (a) This Agreement is consistent with paragraph 14 of the Mexico City
Memorandum of Understanding, signed June 18, 1996,1 which states: 
 “Backup arrangements between two or more operators consequential to in-orbit failure are permitted with the understanding that such an arrangement
shall not impose additional restrictions to other satellite networks operating within the current operating agreement established in accordance with this MOU.” 
 (b) This arrangement is consistent with paragraph 8(e) of the Mexico City Memorandum of Understanding, which reads, in part: 
 “Also, if two or more operators (sic) agree to exchange spectrum, these operators should (sic) develop an arrangement among themselves. ... Such use is subject to agreement among the operators of the networks
concerned.” 
 5. Compliance With the Laws of the Party’s Respective Licensing Administrations. The Parties understand and
accept that nothing in this Agreement shall be construed to require the Parties to take any action or inaction that would violate the laws, regulations, policies, and licensing conditions of their respective Licensing Administrations (Canada in the
case of MSV Canada, and the United States in the case of MSV), including those of Industry Canada (in the case of MSV Canada) and the Federal Communications Commission (in the case of MSV). 
 6. Representations and Warranties of MSV. MSV represents and warrants to MSV Canada as follows: 
 (a) MSV has all requisite legal power and authority to execute, deliver, and perform its obligations under this Agreement. 
 (b) The execution and delivery of this Agreement, and the performance by MSV of its obligations hereunder, have been duly authorized by all necessary
legal action on the part of MSV. 
 (c) The execution, delivery and performance by MSV of this Agreement will not conflict with, or result in
a breach or violation of, any provision of any organizational or governance documents of MSV.

 8.
Term and Termination 
 (a) This Agreement shall commence on the Effective Date, and shall continue in full force and
effect until such time as each of the MSV-1 satellite and the MSV-2 satellite is no longer capable of providing commercial service. 
 (b) Either party shall be entitled to terminate this Agreement: 
 (i) forthwith if the other party files a petition for protection
under the U.S. Bankruptcy Code (11 U.S.C.) or makes an assignment for the benefit of creditors or is named as the debtor in an involuntary bankruptcy proceeding and such proceeding is not dismissed within thirty (30) days; or 
 (ii) forthwith if the other party is adjudicated to be insolvent or makes an assignment for the benefit of creditors or in bankruptcy, or is declared
bankrupt, or takes the benefit of any legislation that may be in force for bankrupt or insolvent debtors or is named as the debtor in an involuntary bankruptcy proceeding and such proceeding is not dismissed within thirty (30) days; 

9. Miscellaneous. 
 (a) This
Agreement may not be amended except by an instrument in writing signed on behalf of each of the parties hereto. 
 (b) This Agreement shall be
governed by and construed in accordance with the laws of the State of New York, without regard to its principles of conflicts of law that would give effect to the application of the law of another jurisdiction. Each of the Parties hereby irrevocably
and unconditionally consents to submit to the non-exclusive jurisdiction of the courts of the State of New York and of the 

  

 3 

 
United States of America, in each case having jurisdiction over the County of New York, for any litigation arising out of or relating to this Agreement, and
the transactions contemplated hereby and thereby (and agrees not to commence any litigation relating thereto except in such courts), and further agrees that service of any process, summons, notice or document by registered mail to its respective
address set forth in this Agreement shall be effective service of process for any litigation brought against it in any such court. Each of the Parties hereby irrevocably and unconditionally waives any objection to the laying of venue of any
litigation arising out of this Agreement or the transactions contemplated by this Lease in the courts of the State of New York or the United States of America, in each case having jurisdiction over the County of New York, and hereby further
irrevocably and unconditionally waives and agrees not to plead or claim in any such court that any such litigation brought in any such court has been brought in an inconvenient forum. 
 (c) This Agreement shall bind and inure to the benefit of MSV, MSV Canada, and their respective successors and assigns. Neither Party shall assign or
transfer this Agreement, or any or all of its rights or obligations hereunder, without the prior written consent of the other Party, which consent shall not be unreasonably withheld. 
 (d) This Agreement may be executed and delivered (including by facsimile transmission) in one or more counterparts, each of which shall be deemed an
original, but all of which together shall constitute one and the same instrument. 
 (e) In the event of such a failure as set forth in
Section 1 or 2 hereof, the Parties agree to cooperate in good faith and take all actions necessary to promptly transfer the customer traffic to the other satellite as contemplated herein. 
 (f) This Agreement is solely with respect to the matters explicitly contained herein, and does not supersede, amend or modify any prior agreements or
understandings between the Parties with respect to any matter other than the subject matter hereof. 
 (g) If any provision of this Agreement
is determined to be invalid, illegal or unenforceable by any governmental entity, the remaining provisions of this Agreement to the extent permitted by law will remain in full force and effect provided that the intent and purpose of the Parties are
not frustrated thereby. In the event of any such determination, the Parties agree to attempt to negotiate in good faith to modify this Agreement to fulfill as closely as possible the original intents and purposes hereof. To the extent permitted by
law, the Parties hereby to the same extent waive any provision of law that renders any provision hereof prohibited or unenforceable in any respect. 
 Please acknowledge your acceptance of the foregoing by executing the countersignature below.
