NOW, THEREFORE, the parties hereto hereby agree as follows:

SECTION 1. Registration Under The Securities Act.

1.1. Registration.

 

  (a)

Each of the parties to this agreement shall cooperate, and SkyTerra shall
prepare and file with the Securities and Exchange Commission (the “SEC”) as soon
as practicable following the execution of this Agreement, a registration
statement on

--------------------------------------------------------------------------------

 

the appropriate form for the purpose of registering under the Securities Act any
and all Common Shares that constitute Acquired Shares for resale by the Holders
(the “Resale Registration Statement”). To the extent that the BCE-Motient
Exchange Agreement has not been entered into at the time of the filing of the
Resale Registration Statement with the SEC, the Acquired Shares shall not
include the Motient Acquired Shares and, upon entry into such an agreement,
SkyTerra will promptly amend the Resale Registration Statement to include any
and all Common Shares that constitute Motient Acquired Shares for resale by the
holders thereof. SkyTerra will cause the Resale Registration Statement to comply
as to form in all material respects with the applicable provisions of the
Securities Act and the rules and regulations thereunder. SkyTerra shall use its
commercially reasonable efforts, and the Holders will cooperate with SkyTerra,
to have the Resale Registration Statement declared effective by the SEC as
promptly as practicable.

 

  (b) SkyTerra shall keep the Resale Registration Statement effective (including
through the filing of any required post-effective amendments) until the earliest
to occur of (i) such time as BCE and its subsidiaries (and their permitted
transferees pursuant to Sections 5.1 (c) and (f) of this Agreement) have sold
all of the Acquired Shares registered thereunder, (ii) the later of (x) 90 days
after BCE and its subsidiaries may no longer be considered affiliates of
SkyTerra for purposes of Rule 144 under the Securities Act and (y) the second
year anniversary of the latest date BCE or any of its subsidiaries receives
Acquired Shares from Motient as specified in the recitals to this agreement and
(iii) the sixth year anniversary of the date hereof; provided, that such date
shall be extended by the amount of time of any period during which the Holders
may not use the Resale Registration Statement as the result of the occurrence of
an event described in Section 1.2(e) (ii), (iii) or (iv) or Section 2.1 below.
Thereafter, SkyTerra shall be entitled to withdraw the Resale Registration
Statement and, upon such withdrawal, the Holders shall have no further right to
sell any of the Acquired Shares pursuant to the Resale Registration Statement
(or any prospectus forming a part thereof).

1.2. Registration Procedures. Subject to the terms and conditions hereof,
SkyTerra shall use its commercially reasonable efforts to effect the
registration and the disposition of the Acquired Shares in accordance with the
intended method of disposition thereof, and pursuant thereto SkyTerra shall as
expeditiously as practicable:

 

  (a)

promptly prepare and file with the SEC the Resale Registration Statement with
respect to the Common Shares that are Acquired Shares (and any amendments,
including any post-effective amendments or supplements to the Resale
Registration Statement and prospectus included therein SkyTerra deems to be
necessary) and use its commercially reasonable efforts to cause the Resale
Registration Statement to become effective and to comply with the provisions of
the Securities Act applicable to it; provided, that before filing the Resale
Registration Statement or prospectus or any amendments or supplements thereto,
SkyTerra shall furnish to counsel for the Holders copies of all such documents
proposed to be filed, including documents incorporated by reference in the
Resale

--------------------------------------------------------------------------------

 

Registration Statement and, if requested by the Holders, the exhibits
incorporated by reference so as to provide the Holders and their counsel a
reasonable opportunity to review and comment on such documents, and SkyTerra
(i) will make such changes and additions thereto as reasonably requested by
counsel to the Holders prior to filing the Resale Registration Statement or
amendment thereto or any prospectus or any supplement thereto and (ii) if any of
the Holders is an underwriter or controlling person of SkyTerra, will include
therein material relating to the Holders or the plan of distribution for the
Acquired Shares registered thereunder, furnished to SkyTerra in writing, which,
in the reasonable judgment of such Holder, should be included;

 

  (b) furnish to the Holders such number of copies of the Resale Registration
Statement, each amendment and supplement thereto, the prospectus included in the
Resale Registration Statement and such other documents as the Holders may
reasonably request in order to facilitate the disposition of the Acquired Shares
registered thereunder; provided, however, that SkyTerra shall have no obligation
to furnish copies of a final prospectus if the conditions of Rule 172(c) under
the Securities Act are satisfied by SkyTerra;

 

  (c) prepare and file with the SEC such amendments and supplements to the
Resale Registration Statement and the prospectus used in connection therewith as
may be necessary to keep the Resale Registration Statement effective for the
time period as specified in Section 1.1 in order to complete the disposition of
the Acquired Shares covered by the Resale Registration Statement and comply with
the provisions of the Securities Act with respect to the disposition of all
Acquired Shares covered thereby during such period in accordance with the
intended methods of disposition thereof as set forth in the Resale Registration
Statement, including without limitation identification of the permitted
transferees of the Holders;

 

  (d) use its commercially reasonable efforts to register or qualify the
Acquired Shares covered by the Resale Registration Statement under such other
securities or blue sky laws of such jurisdictions as the Holders reasonably
request and do any and all other acts and things which may be reasonably
necessary or advisable to enable the Holders to consummate the disposition of
the Acquired Shares covered thereby in such jurisdictions (provided that
SkyTerra shall not be required to (i) qualify generally to do business in any
jurisdiction where it would not otherwise be required to qualify but for this
subsection, (ii) subject itself to taxation in any such jurisdiction or
(iii) consent to general service of process in any such jurisdiction);

 

  (e)

notify the Holders, at any time when a prospectus relating thereto is required
to be delivered under the Securities Act, (i) when the Resale Registration
Statement or any post-effective amendment has become effective under the
Securities Act, (ii) of any written request by the SEC for amendments or
supplements to the Resale Registration Statement or prospectus, (iii) of the
happening of any event as a result of which the prospectus included in the
Resale Registration Statement

--------------------------------------------------------------------------------

 

contains an untrue statement of a material fact or omits any fact necessary to
make the statements therein, in light of the circumstances under which they were
made, not misleading (whereupon the Holders shall immediately cease any offers,
sales or other distribution of Acquired Shares registered thereunder), and,
subject to 1.3(c), SkyTerra shall promptly prepare a supplement or amendment to
such prospectus so that, as thereafter used by the Holders for the resale of
Acquired Shares, such prospectus shall not contain an untrue statement of a
material fact or omit to state any fact necessary to make the statements
therein, in light of the circumstances under which they were made, not
misleading, and (iv) of the issuance of any stop order suspending the
effectiveness of the Resale Registration Statement, or of any order suspending
or preventing the use of any related prospectus or suspending the qualification
of any of the Acquired Shares included in the Resale Registration Statement for
sale or distribution in any jurisdiction;

 

  (f) in the event of the issuance of any stop order suspending the
effectiveness of the Resale Registration Statement, or of any order suspending
or preventing the use of any related prospectus or suspending the qualification
of any Acquired Shares included in the Resale Registration Statement for sale or
distribution in any jurisdiction, SkyTerra shall use its commercially reasonable
efforts promptly to obtain the withdrawal of such order and shall prepare and
file an amended or supplemented prospectus, if required;

 

  (g) provide a transfer agent and registrar for all Acquired Shares covered by
the Resale Registration Statement not later than the effective date of the
Resale Registration Statement;

 

  (h) use its commercially reasonable efforts to cause the Acquired Shares
covered by the Resale Registration Statement to be registered with or approved
by such other governmental agencies or authorities as may be necessary to enable
the Holders to complete the disposition of the Acquired Shares covered by the
Resale Registration Statement and comply with the provisions of the Securities
Act with respect to the disposition of all Acquired Shares covered by the Resale
Registration Statement during such period in accordance with the intended
methods of disposition by the Holders thereof set forth in the Resale
Registration Statement;

 

  (i) make available for inspection by the Holders, any underwriter
participating in any disposition pursuant to the Resale Registration Statement
on behalf of the Holders, and any attorney, accountant or other agent retained
by the Holders or underwriter, all financial and other records, pertinent
corporate documents and properties of SkyTerra, and cause SkyTerra’s officers,
managers, employees and independent accountants to supply all information
reasonably requested by SkyTerra or such underwriter, attorney, accountant or
agent in connection with the Resale Registration Statement (and, if required by
the underwriter or underwriters participating in any such disposition, enter
into an underwriting agreement with such underwriter or underwriters containing
customary provisions for secondary offerings of this sort); and

--------------------------------------------------------------------------------

  (j) make generally available to its stockholders a consolidated earnings
statement (which need not be audited) for the 12 months beginning after the
effective date of the Resale Registration Statement as soon as reasonably
practicable after the end of such period, which earnings statement shall satisfy
the requirements of an earning statement under Section 11(a) of the Securities
Act.

1.3. Other Procedural Matters.

 

  (a) SEC Correspondence. SkyTerra shall make available to the Holders promptly
after the same is prepared and publicly distributed, filed with the SEC, or
received by SkyTerra, one copy of the Resale Registration Statement and any
amendment thereto, each preliminary prospectus and each amendment or supplement
thereto, each letter written by or on behalf of SkyTerra to the SEC or the staff
of the SEC (or other governmental agency or self-regulatory body or other body
having jurisdiction, including any domestic or foreign securities exchange), in
each case relating to the Resale Registration Statement. SkyTerra will promptly
respond to any and all comments received from the SEC, with a view towards
causing the Resale Registration Statement or any amendment thereto to be
declared effective by the SEC as soon as practicable and shall file an
acceleration request as soon as practicable following the resolution or
clearance of all SEC comments or, if applicable, following notification by the
SEC that the Resale Registration Statement or any amendment thereto will not be
subject to review.

 

  (b) SkyTerra may require the Holders to furnish to SkyTerra any other
information regarding the Holders and the disposition of Acquired Shares,
including without limitation the plan of distribution of the Acquired Shares, as
SkyTerra reasonably determines, is required to be included in the Resale
Registration Statement.

 

  (c) Each of the Holders agrees that, upon notice from SkyTerra of the
happening of any event as a result of which the prospectus included in the
Resale Registration Statement contains an untrue statement of a material fact or
omits any material fact necessary to make the statements therein not misleading
(a “Suspension Notice”), the Holders will forthwith discontinue disposition of
Acquired Shares pursuant to the Resale Registration Statement until the Holders
are advised in writing by SkyTerra that the use of the prospectus may be resumed
and is furnished with a supplemented or amended prospectus as contemplated by
Section 1.2 hereof; provided, however, that such postponement of sales of
Acquired Shares by the Holders shall not in any event exceed (i) twenty
(20) consecutive days or (ii) forty-five (45) days in the aggregate in any 12
month period. If SkyTerra shall give the Holders any Suspension Notice or impose
a Lockup Period (as defined below), SkyTerra shall extend the period of time
during which SkyTerra is required to maintain the Resale Registration Statement
effective pursuant to this Agreement by the number of days during the period
from and including the date of the giving of such Suspension Notice to and
including the date the Holders either are advised by SkyTerra that the use of
the prospectus may be resumed or by the Lockup Period, as applicable. In any
event, SkyTerra shall not be entitled to deliver more than a total of three
(3) Suspension Notices in any 12 month period.

--------------------------------------------------------------------------------

  (d) Neither SkyTerra nor the Holders shall permit any officer, manager,
underwriter, broker or any other person acting on behalf of SkyTerra or the
Holders to use any free writing prospectus (as defined in Rule 405 under the
Securities Act) in connection with the Resale Registration Statement filed
pursuant to this Agreement without the prior written consent of SkyTerra, the
Holders and any underwriter.

1.4. Expenses.

 

  (a) Registration Expenses. All Registration Expenses shall be borne by
SkyTerra.

 

  (b) Selling Expenses. All expenses incident to the Holders’ performance of or
compliance with this Agreement, including, without limitation, all fees and
expenses of counsel for the Holders, fees and expenses of the Holders’ transfer
agent, and any broker or dealer discounts or commissions attributable to the
disposition of Acquired Shares shall be borne solely by the Holders.

SECTION 2. LOCKUP Agreement.

2.1. Lockup. Each of the Holders hereby agrees, beginning 60 days (extended for
any period during a Suspension Notice during the first 60 days) following the
Initial Closing Date (as defined in the Exchange Agreement, dated as of May 6,
2006, by and among Motient, Motient Ventures Holding Inc. and SkyTerra), to not
effect any public sale or distribution (including any sales pursuant to Rule
144) of equity securities of SkyTerra, or any securities convertible into or
exchangeable or exercisable for such securities, during the seven days prior to
and the 90-day period beginning on the effective date of any primary
underwritten registered public offering of equity securities of SkyTerra or
securities convertible or exchangeable into or exercisable for equity securities
of SkyTerra, unless the underwriters managing such registered public offering
otherwise consent in writing, and the Holders will deliver an undertaking to the
managing underwriters (if requested) consistent with this covenant (in each
case, a “Lockup Period”). Notwithstanding the foregoing, the Holders shall not
be obligated to comply with the provisions of this Section 2.1 (i) more than two
times in any 12-month period and (ii) unless all officers and directors of
SkyTerra and Apollo Investment Fund IV, L.P., Apollo Overseas Partners IV, L.P.,
AIF IV/RRRR LLC, AP/RM Acquisition LLC and ST/RRRR LLC are also subject to a
Lockup Period on substantially the same terms as the Holders. Notwithstanding
the foregoing, this Section 2.1 shall not apply to any Holder (or transferee of
any such Holder in accordance with Section 5.1 hereof) who does not, together
with its Affiliates, own or have the right to acquire or vote with respect to
Common Shares consisting of, or exchangeable upon disposition for, in the
aggregate, more than four percent (4%) of the total combined voting power of all
Common Shares then outstanding.

SECTION 3. Indemnification.

3.1. Indemnification by SkyTerra. SkyTerra agrees to indemnify, to the extent
permitted by law, the Holders, their officers, directors, employees and
Affiliates and each Person

--------------------------------------------------------------------------------

who controls the Holders (within the meaning of the Securities Act) against all
losses, claims, damages, liabilities, and expenses caused by any untrue or
alleged untrue statement of material fact contained in the Resale Registration
Statement or any prospectus forming a part of the Resale Registration Statement
or any “issuer free writing prospectus” (as defined in Securities Act Rule 433),
or any amendment thereof or supplement thereto or any omission or alleged
omission of a material fact required to be stated therein or necessary to make
the statements therein, in light of the circumstances under which they were
made, not misleading or any violation or alleged violation by SkyTerra of the
Securities Act, the Exchange Act or applicable “blue sky” laws, except that
SkyTerra shall not be liable to any Holder pursuant to this Section 3.1 insofar
as the same are made in reliance and in conformity with any information
furnished in writing to SkyTerra by such Holder expressly for use therein or by
the failure of such Holder to deliver a copy of such registration statement or
prospectus or any amendments or supplements thereto as required by law after
SkyTerra has furnished such Holder with a sufficient number of copies of the
same.

3.2. Indemnification by BCE. In connection with the Resale Registration
Statement in which the Holders are participating, each Holder shall furnish to
SkyTerra in writing such information as SkyTerra reasonably requests for use in
connection with any such registration statement or prospectus and, to the extent
permitted by law, shall indemnify SkyTerra, its directors, officers, employees
and Affiliates, and each Person who controls SkyTerra (within the meaning of the
Securities Act), against any losses, claims, damages, liabilities, and expenses
resulting from any untrue or alleged untrue statement of material fact contained
in the Resale Registration Statement, the prospectus or preliminary prospectus
forming a part of the Resale Registration Statement or any amendment thereof or
supplement thereto or any omission or alleged omission of a material fact
required to be stated therein or necessary to make the statements therein, in
light of the circumstances under which they were made, not misleading, but only
to the extent that any information so furnished in writing by such Holder
contains such untrue statement or omits a material fact required to be stated
therein necessary to make the statements therein not misleading; provided,
however, that any such obligation of such Holder to indemnify SkyTerra hereunder
shall be limited to the net proceeds to such Holder and its permitted
transferees from the sale of the Acquired Shares pursuant to the Resale
Registration Statement.

3.3. Indemnification Procedures. Any Person entitled to indemnification
hereunder shall (i) give prompt written notice to the indemnifying party of any
claim with respect to which it seeks indemnification (provided that the failure
to give prompt notice shall not impair any Person’s right to indemnification
hereunder to the extent such failure has not prejudiced the indemnifying party)
and (ii) unless in such indemnified party’s reasonable judgment a conflict of
interest between such indemnified and indemnifying parties may exist with
respect to such claim, permit such indemnifying party to assume the defense of
such claim with counsel reasonably satisfactory to the indemnified party. If
such defense is assumed, the indemnifying party shall not be subject to any
liability for any settlement made by the indemnified party without its consent
(but such consent shall not be unreasonably withheld). An indemnifying party who
is not entitled to, or elects not to, assume the defense of a claim shall not be
obligated to pay the fees and expenses of more than one counsel (in addition to
local counsel) for all parties indemnified by such indemnifying party with
respect to such claim, unless in the reasonable judgment of any indemnified
party there may be one or more legal or equitable defenses

--------------------------------------------------------------------------------

available to such indemnified party that are in addition to or may conflict with
those available to another indemnified party with respect to such claim. Failure
to give prompt written notice shall not release the indemnifying party from its
obligations hereunder.

3.4. Investigation; Contribution. The indemnification provided for under this
Agreement shall remain in full force and effect regardless of any investigation
made by or on behalf of the indemnified party or any officer, director, or
controlling Person of such indemnified party and shall survive the transfer of
securities. If the indemnification provided under Section 3.1 or Section 3.2 of
this Agreement is held by a court to be unavailable or unenforceable in respect
of any losses, claims, damages, liabilities or expenses referred to herein, then
each applicable indemnifying party, in lieu of indemnifying such indemnified
party, shall contribute to the amount paid or payable by such indemnified Person
as a result of such losses, claims, damages, liabilities or expenses in such
proportion as is appropriate to reflect the relative fault of the indemnifying
party on the one hand and of the indemnified party on the other in connection
with the statements or omissions that result in such losses, claims, damages,
liabilities or expenses as well as any other relevant equitable considerations.
The relative fault of the indemnifying party on the one hand and of the
indemnified Person on the other shall be determined by reference to, among other
things, whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by the indemnifying party or by the indemnified party, and by such
party’s relative intent, knowledge, access to information and opportunity to
correct or prevent such statement or omission. In no event shall the liability
of each Holder for contribution pursuant to this Section 3.4 be greater than the
amount for which such Holder would have been liable pursuant to Section 3.2 had
indemnification been available and enforceable.

SECTION 4. RULE 144 TRANSACTIONS.

4.1. Undertaking to File Reports and Cooperate in Rule 144 Transactions. For as
long as the Holders continue to hold any Acquired Shares, SkyTerra shall use its
commercially reasonable efforts to file with the SEC, on a timely basis, all
annual, quarterly and other periodic reports required to be filed by it under
Sections 13 and 15(d) of the Exchange Act, and the rules and regulations
thereunder; provided, however, that the foregoing shall not be construed to
require SkyTerra to prepare and file periodic reports if it is not required to
do so under the Exchange Act. In the event of any proposed sale by any Holder of
Acquired Shares pursuant to Rule 144 under the Securities Act or otherwise as
provided herein, which sale is to be made in accordance with the terms of
Section 5.1(b) hereof, SkyTerra shall use its commercially reasonable efforts to
cooperate with such Holder so as to enable such sales to be made in accordance
with applicable laws, rules and regulations, the requirements of the transfer
agent of SkyTerra, and the reasonable requirements of the broker through which
the sales are proposed to be executed, and shall, upon written request, furnish
unlegended certificates representing ownership of the Common Shares sold
thereby, such certificates to be furnished in such numbers and denominations as
such Holder may reasonably request.

--------------------------------------------------------------------------------

SECTION 5. RESTRICTIONS ON TRANSFER.

5.1. Permitted Transfers. Each of the Holders hereby agrees that, until it and
any permitted transferees under paragraph (c) or (f) hereunder have disposed of
all of the Acquired Shares, it will not, directly or indirectly, without the
prior written consent of SkyTerra, sell, distribute, transfer or otherwise
dispose (in each case, a “Disposition”) of any Acquired Shares except:

 

  (a) sales of Acquired Shares pursuant to the Resale Registration Statement; or

 

  (b) sales of Acquired Shares pursuant to Rule 144 under the Securities Act; or

 

  (c) sales or transfers of Acquired Shares to any Person or group of related
Persons who would immediately thereafter not own or have the right to acquire or
vote with respect to Common Shares consisting of, in the aggregate, more than
ten percent (10%) (with each Person, other than Affiliates of the transferring
Holder, considered individually and not in the aggregate with other transferees)
of the total combined voting power of all Common Shares then outstanding;
provided, however, that in each such case, the transferee shall receive and hold
such Acquired Shares subject to, and the transferee and all of the transferees’
Affiliates shall agree to be bound by, all the terms of this Agreement, which
terms shall also inure to the benefit of such transferees, and there shall be no
further transfer of such Acquired Shares, except in accordance with the
provisions of this Section 5.1; or

 

  (d) a bona fide pledge of or the granting of a security interest in the
Acquired Shares to an institutional lender for money borrowed, provided that
such lender acknowledges in writing that it has received a copy of this
Agreement and agrees, upon its becoming the owner of, or obtaining dispositive
authority with respect to or in connection with any disposition of, any such
Acquired Shares, to be bound by the provisions of this Agreement in connection
with any right it may have to dispose of any such Acquired Shares (and, upon
agreeing so to be bound, the provisions of this Agreement shall inure to the
benefit of such party); or

 

  (e) sales or transfers of Acquired Shares pursuant to a tender or exchange
offer; or

 

  (f) dispositions of Acquired Shares (i) by BCE or any subsidiary of BCE to any
subsidiary of BCE or to a successor corporation of BCE or (ii) by any Holder
whos is not BCE or a subsidiary of BCE to any subsidiary of such Holder or to a
successor of such Holder or to an Affiliate of such Holder; provided, however,
that in each such case, the transferee shall receive and hold such Acquired
Shares subject to, and the transferee and all of the transferees’ Affiliates
shall agree to be bound by, all the terms of this Agreement, which terms shall
also inure to the benefit of such transferees, and there shall be no further
transfer of such Acquired Shares, except in accordance with the provisions of
this Section 5.1; or

 

  (g) dispositions pursuant to any merger, consolidation, reorganization or
recapitalization to which SkyTerra is a party or in connection with any
reclassification of the Acquired Shares;

provided, that in the event that any Holder seeks to effect a Disposition of any
Acquired Shares pursuant to clauses (b), (c) or (f) of this Section 5.1,
(i) such Disposition is made in compliance

--------------------------------------------------------------------------------

with applicable securities laws, and (ii) prior to such Disposition, BCE shall
have delivered to SkyTerra an opinion of counsel stating that such Disposition
(A) is permitted by this Agreement and (B) does not require registration under
the Securities Act; provided, that with respect to Dispositions pursuant to
Section 5.1(b) or (f), such opinion shall only be required if requested by
SkyTerra’s transfer agent and in any event no opinion shall be required for
Dispositions pursuant to Rule 144(k) under the Securities Act.
