WHEREAS, in order to induce the Holder to consummate the transactions under the
Subscription Agreement and the Cooperation Agreement, SkyTerra has agreed to
provide certain registration rights to the Holder on the terms and subject to
the conditions set forth herein.
 
NOW, THEREFORE, the parties hereto hereby agree as follows:
 
SECTION 1. REGISTRATION UNDER THE SECURITIES ACT.
 
1.1 Registration.
 
(a) SkyTerra shall use its reasonable best efforts to file with the Securities
and Exchange Commission (the “SEC”) no later than thirty (30) Business Days
after the later of (i) two years following the Effective Date (the “Second
Anniversary”) and (ii) the receipt of a written request from the Holder
requesting the registration of all of the Effective Date Shares and all of the
Trigger Shares then held by the Holder (the “Registration Request”, and along
with the Second Anniversary, the “Resale Registration Conditions”) a
registration statement on the appropriate form for the purpose of registering
such Acquired Shares under the Securities Act for resale by the Holder (the
“Resale Registration Statement”). If, at the time of the filing of the Resale
Registration Statement any or all of the Trigger Shares have not yet been
issued, SkyTerra will upon the written request of the Holder and receipt by the
Holder of any or all of the Trigger Shares (the “Second Registration Request”),
use its reasonable best efforts to file one additional registration statement on
the appropriate form or file a post-effective amendment to the Resale
Registration Statement for the purpose of registering the Trigger Shares that
have been subsequently acquired by the Holder (the “Second Resale Shelf”) no
later than thirty (30) Business Days following such Second Registration Request,
provided, however, that SkyTerra shall not be obligated to file more than one
registration statement in any six-month period pursuant to this Section 1.1 or
more than one Second Resale Shelf or Third Resale Shelf (as defined herein).
Additionally, SkyTerra shall use its reasonable best efforts to file one
additional registration statement (or a post effective amendment to the Resale
Registration Statement or Second Resale Shelf) (the "Third Resale Shelf") on the
appropriate form for the purpose of registering the Phase I Shares for resale no
later than thirty (30) Business Days following (i) one year following the Phase
1 Completion Date (the "Phase I Anniversary"), and (ii) the receipt of a written
request by the Holder requesting the registration of all of the Phase I Shares
then held by the Holder (the "Third Registration Request"). At the request of
the Holder, the Third Resale Shelf will include any Trigger Shares not
previously included in the Resale Registration Statement or Second Resale Shelf.
In the event of a Second Resale Shelf or a Third Resale Shelf, all other terms
applicable to the Resale Registration Statement, other than with respect to the
timing of its filing, shall be applicable to the Second Resale Shelf or the
Third Resale Shelf, as applicable, and all references herein to the Resale
Registration Statement shall be deemed to include the Second Resale Shelf and
the Third Resale Shelf, as applicable, (references to the Resale Registration
Conditions will include the Second Registration Request or the Third
Registration Request, as applicable). 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 reasonable best efforts, and the Holder will
provide reasonable cooperation with SkyTerra, to have the Resale Registration
Statement declared effective by the SEC as promptly as practicable, but no later
than one hundred fifty (150) calendar days following the occurrence of the
applicable Resale Registration Conditions. Upon notice to the Holder, SkyTerra
may postpone filing or effecting the Resale Registration Statement, the Second
Resale Shelf and/or Third Resale Shelf for a reasonable time, but not exceeding
ninety (90) calendar days from the receipt of such notice, if (i) SkyTerra’s
Board of Directors (the “Board”) shall determine that effecting the registration
would adversely affect an offering of securities of SkyTerra the preparation of
which had then been commenced, or (ii) SkyTerra is in possession of material
non-public information the disclosure of which would not be in the best interest
of SkyTerra. Nothing herein shall prevent SkyTerra from including SkyTerra
securities held by other holders in the Resale Registration Statement, any
Second Resale Shelf or Third Resale Shelf. Additionally, in the event SkyTerra
files the Second Resale Shelf or the Third Resale Shelf, nothing in this
Agreement shall prevent SkyTerra from combining the latest registration
statement with any registration statement previously filed for the benefit of
the Holder.
 

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

 
(b) SkyTerra shall keep the Resale Registration Statement effective (including
through the filing of any required post-effective amendments) until the earlier
to occur of (i) such time as the Holder has sold all of the Acquired Shares
registered thereunder or (ii) such time as the shares no longer constitute
Acquired Shares.
 
(c) The plan of distribution contained in the Resale Registration Statement
shall be substantially in the form attached as Exhibit A hereto.
 
1.2 Registration Procedures. Subject to the terms and conditions hereof,
SkyTerra shall use its reasonable best efforts to effect the registration and
the disposition of the Acquired Shares in accordance with the intended method of
disposition thereof (which method will not include an underwritten offering),

with the filing deadlines set forth in Section 1.1(a), prepare and file with the

SkyTerra deems to be necessary) and use its reasonable best efforts to cause the
Resale Registration Statement to become effective as promptly as reasonably
possible 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 (other than filings made pursuant to
the Exchange Act or exhibits to such registration statements), SkyTerra shall

Statement, so as to provide the Holder and their counsel a reasonable

Holder prior to filing the Resale Registration Statement or amendment thereto or

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

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 thereof as set forth in the
Resale Registration Statement;

 

 
(d)
use its reasonable best efforts to register or qualify the Acquired Shares under
such other securities or blue sky laws of such jurisdictions as the Holder
reasonably request and do any and all other acts and things which may be
reasonably necessary or advisable to enable the Holder to consummate the

subsection, (ii) subject itself to taxation in any such jurisdiction or (iii)
consent to general service of process in any such jurisdiction);

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

circumstances under which they were made, not misleading (whereupon the Holder
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 Holder for the resale of the 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

thereto, each preliminary prospectus and each amendment or supplement thereto
(other than filings made pursuant to the Exchange Act or exhibits to such
registration statements), 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 reasonably
practicable and shall file an acceleration request as soon as reasonably
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)
The Holder shall furnish SkyTerra with any other information regarding the
Holder and the disposition of the Acquired Shares, including without limitation
the plan of distribution of the Acquired Shares (substantially in the form
attached as Exhibit A hereto), as SkyTerra reasonably determines, is required to
be included in the Resale Registration Statement. At least ten (10) Business
Days prior to the first anticipated filing date of a Registration Statement for
any registration under this Agreement, SkyTerra will notify the Holder of the
information SkyTerra requires from the Holder other than information contained
in the Selling Securityholder Questionnaire attached hereto as Exhibit B, which
shall be completed and delivered to SkyTerra promptly concurrently with any
request for inclusion in any Resale Registration Statement pursuant to Section
1.1.

 

 
(c)
The Holder 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 Holder will forthwith discontinue disposition of Acquired Shares
pursuant to the Resale Registration Statement until the Holder is 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 Holder 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. The
Holder agrees to keep confidential the existence of any Suspension Notice and,
if disclosed to the Holder, the facts and circumstances giving rise thereto. If
SkyTerra shall give the Holder any Suspension Notice, 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 Holder is advised by SkyTerra
that the use of the prospectus may be resumed. In any event, SkyTerra shall not
be entitled to deliver more than a total of three (3) Suspension Notices in any
12 month period.

prior written consent of SkyTerra and the Holder.

 
1.4 Expenses.

SECTION 2. LOCKUP AGREEMENT.
 
2.1 The Holder hereby agrees 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 underwritten registered public offering (or the filing
of a prospectus supplement to any effective shelf registration statement) of
equity securities of SkyTerra or securities convertible or exchangeable into or
exercisable for equity securities of SkyTerra (except as part of such
underwritten registration), unless the underwriters managing the registered
public offering otherwise consent in writing, and the Holder will deliver an
undertaking to the managing underwriters (if requested) consistent with this
covenant. The Holder shall not be obligated to comply with the provisions of
this Section 2.1 more than two times in any 12-month period.
 
SECTION 3. INDEMNIFICATION.
 
3.1 Indemnification by SkyTerra. SkyTerra agrees to indemnify, to the extent
permitted by law, each of the Holder, its officers, directors, employees and
Affiliates and each Person who controls the Holder (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 insofar as the same are made in reliance and in conformity with any
information furnished in writing to SkyTerra by the Holder expressly for use
therein or by the failure of the 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 the Holder with a sufficient number of copies
of the same.
 
5

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

 
3.2 Indemnification by the Holder. In connection with the Resale Registration
Statement in which the Holder is participating, the Holder shall furnish to
SkyTerra in writing the Selling Securityholder Questionnaire and such other
information as SkyTerra reasonably requests for use in connection with any such
registration statement or prospectus and, to the extent permitted by law, the
Holder 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 the 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 the obligation of the Holder to indemnify SkyTerra hereunder shall
be limited to the net proceeds to the Holder from the sale of the Holder’s
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.
 
6

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

 
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 the Holder for contribution pursuant to this Section 3.4 be greater than the
amount for which the 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. SkyTerra
shall use its reasonable best 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 for so long as such disclosure is required to allow sales of Acquired
Shares pursuant to Rule 144 under the Securities Act; 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 the 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 hereof, SkyTerra shall use its
reasonable best efforts to cooperate with the 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
Acquired Shares sold thereby, such certificates to be furnished in such numbers
and denominations as the Holder may reasonably request.
 
SECTION 5. RESTRICTIONS ON TRANSFER.
 
5.1 Permitted Transfers. The Holder hereby agrees that until (i) the Second
Anniversary, the Holder may not transfer any of the Effective Date Shares or the
Trigger Shares, and (ii) the Phase I Anniversary, the Holder may not transfer
any of the Phase I Shares; provided, however, that the Holder may at any time
transfer any of such shares to an Affiliate of the Holder (so long as such
Affiliate is an “accredited investor” as defined in Rule 501 of Regulation D
promulgated under the Securities Act and agrees in a written instrument in form
and substance reasonably satisfactory to the Company to be bound by the terms
and provisions of this Agreement if, and to the fullest extent as, the Holder).
From and after the Second Anniversary with respect to the Effective Date Shares
and the Trigger Shares, and the Phase I Anniversary with respect to the Phase I
Shares, the Holder may transfer any of the Acquired Shares: (i) pursuant to an
effective registration statement under the Securities Act or (ii) pursuant to an
available exemption from registration under the Securities Act (including sales
permitted pursuant to Rule 144) and applicable state securities laws (subject to
the Company’s request for reasonable documentation, including opinions of
counsel, that such sale or transfer is made pursuant to an available exemption
from registration).
 
7

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

 
SECTION 6. TRANSFER OF REGISTRATION RIGHTS.
 
The Holder may not transfer or assign all or any portion of its rights under
this Agreement (except by operation of law pursuant to a merger or similar
business combination) unless such transferee or assignee is an Affiliate (that
is also an “Accredited Investor”) that agrees in a written instrument in form
and substance reasonably satisfactory to SkyTerra to be bound by this Agreement
as fully as if it were an initial signatory hereto, and any such transferee may
thereafter make corresponding assignments in accordance with this proviso but
only to other Affiliates of the initial Holder. For purposes of clarity, any
assignee permitted by the preceding sentence must remain an Affiliate of the
initial Holder until the shares held by such Affiliate are disposed or until the
Holder would be permitted to transfer such shares pursuant to the second
sentence of Section 5 hereto. In the event any Acquired Shares are transferred
to one or more Affiliates in a manner permitted by this Agreement, the Holder
shall notify SkyTerra in writing of a single Person that shall be the authorized
representative to receive notices and take all actions on behalf of the Holder
and/or its permitted Affiliate assignees.

satisfactory to the Holder (which such opinion maybe relied on by the Holder),

Exhibit A
 
PLAN OF DISTRIBUTION
 
SkyTerra is registering the shares of common stock covered by this prospectus
for the selling stockholder. Pursuant to a registration rights agreement, dated
as of [Closing Date], SkyTerra agreed to register the resale of the common stock
owned by the selling stockholder and to indemnify the selling stockholder
against certain liabilities related to the selling of the common stock,
including liabilities arising under the Securities Act. Under the registration
rights agreement, SkyTerra also agreed to pay the costs and fees of registering
the shares of common stock; however, the selling stockholder will pay any
brokerage commissions relating to the sale of the shares of common stock.
 
Inmarsat and any of its permitted transferees or other successors-in-interest
may, from time to time, sell, transfer or otherwise dispose of any or all of
their shares of Common Stock or interests in shares of Common Stock on any stock
exchange, market or trading facility on which the shares are traded or in
private transactions.  These dispositions may be at fixed prices, at prevailing
market prices at the time of sale, at prices related to the prevailing market
price, at varying prices determined at the time of sale, or at negotiated
prices. Inmarsat may use one or more of the following methods when disposing of
the shares or interests therein:
 

•
ordinary brokerage transactions and transactions in which the broker-dealer
solicits purchasers;

 

•
block trades in which the broker-dealer will attempt to sell the shares as agent
but may position and resell a portion of the block as principal to facilitate
the transaction;

 

•
purchases by a broker-dealer as principal and resale by the broker-dealer for
its account;

 

•
an exchange distribution in accordance with the rules of the applicable
exchange;

 

•
privately negotiated transactions;

 

•
short sales entered into after the effective date of the registration statement
of which the prospectus is a part;

 

•
through the writing or settlement of options, swaps, derivatives or other
hedging transactions, whether through an options exchange or otherwise;

 

•
broker-dealers may agree with Inmarsat to sell a specified number of such shares
at a stipulated price per share;

 

•
in the over the counter market;

 

•
a combination of any such methods of disposition; and

 

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

 

•
any other method permitted pursuant to applicable law.

 
Inmarsat may also sell shares under Rule 144 under the Securities Act, if
available, rather than under this prospectus.
 
Broker-dealers engaged by Inmarsat may arrange for other broker-dealers to
participate in sales.  Broker-dealers may receive commissions or discounts from
Inmarsat (or, if any broker-dealer acts as agent for the purchaser of shares,
from the purchaser) in amounts to be negotiated. 
 
Inmarsat may from time to time pledge or grant a security interest in some or
all of the Shares owned by them and, if they default in the performance of their
secured obligations, the pledgees or secured parties may offer and sell shares
of Common Stock from time to time under the prospectus, or under an amendment to
the prospectus under Rule 424(b) or other applicable provision of the Securities
Act of 1933, as amended (the “Securities Act”), amending the list of selling
stockholders to include the pledgee, transferee or other successors in interest
as selling stockholders under the prospectus. Inmarsat does not expect these
commissions and discounts to exceed what is customary in the types of
transactions involved.
 
Inmarsat also may transfer the shares of common stock in other circumstances, in
which case the transferees, pledgees or other successors in interest will be the
selling beneficial owners for purposes of the prospectus.
 
In connection with the sale of the shares of Common Stock or interests in shares
of Common Stock, Inmarsat may enter into hedging transactions with
broker-dealers or other financial institutions, which may in turn engage in
short sales of the common stock in the course of hedging the positions they
assume. Inmarsat may also sell shares of Common Stock short and deliver these
securities to close out their short positions, or loan or pledge the common
stock to broker-dealers that in turn may sell these securities. Inmarsat may
also enter into option or other transactions with broker-dealers or other
financial institutions or the creation of one or more derivative securities
which require the delivery to such broker-dealer or other financial institution
of shares offered by the prospectus, which shares such broker-dealer or other
financial institution may resell pursuant to the prospectus (as supplemented or
amended to reflect such transaction).
 
Inmarsat and any broker-dealer or agents that are involved in selling the shares
of Common Stock may be deemed to be “underwriters” within the meaning of the
Securities Act in connection with such sales. In such event, any commissions
received by such broker-dealers or agents and any profit on the resale of Common
Stock purchased by them may be deemed to be underwriting commissions or
discounts under the Securities Act. Inmarsat has informed SkyTerra that it does
not have any written or oral agreement or understanding, directly or indirectly,
with any person to distribute the Common Stock.
 
Once sold under the registration statement, of which this prospectus forms a
part, the shares of Common Stock will be freely tradable in the hands of persons
other than our affiliates.
 
2

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

 
The selling shareholder may offer its shares of common stock in one or more
offerings pursuant to one or more prospectus supplements, if required by
applicable law, and any such prospectus supplement will set forth the terms of
the relevant offering to the extent required.
 
The selling stockholder will act independently of SkyTerra in making decisions
with respect to the timing, manner and size of each sale. The selling
stockholder may sell the common stock on the NASDAQ Global Select Market, the
NASDAQ Global Market, the NASDAQ Capital Market or otherwise, at market prices
prevailing at the time of sale, at prices related to the prevailing market
prices, or at negotiated prices.
 
The selling stockholder may negotiate and pay broker-dealers' commissions,
discounts or concessions for their services. Broker-dealers engaged by the
selling stockholder may allow other broker-dealers to participate in resales.
The selling stockholder and any broker-dealers involved in the sale or resale of
the common stock may qualify as "underwriters" within the meaning of Section
2(a)(11) of the Securities Act. In addition, the broker-dealers' commissions,
discounts or concessions may qualify as underwriters' compensation under the
Securities Act. If the selling stockholder qualifies as an "underwriter," it
will be subject to the prospectus delivery requirements of Section 5(b)(2) of
the Securities Act.
