Ladies and Gentlemen:

          ORBCOMM Inc., a Delaware corporation (the "Company"), proposes to
issue and sell, and each person or entity (each, a "Selling Stockholder")
identified as a Selling Stockholder in Schedule C annexed hereto proposes to
sell, to the underwriters named in Schedule A annexed hereto (the
"Underwriters"), for whom you are acting as representative, an aggregate of
[________] shares (the "Firm Shares") of common stock, $0.001 par value (the
"Common Stock"), of the Company, of which [# of firm shares from company] Firm
Shares are to be issued and sold by the Company and an aggregate of [# of firm
shares from selling stockholders] Firm Shares are to be sold by the Selling
Stockholders. The number of Firm Shares to be sold by each Selling Stockholder
is the number of Firm Shares set forth opposite the name of such Selling
Stockholder in Schedule C annexed hereto. In addition, solely for the purpose of
covering over-allotments, the Company proposes to grant to the Underwriters the
option to purchase from the Company up to an additional [________] shares of
Common Stock (the "Additional Shares"). The Firm Shares and the Additional
Shares are hereinafter collectively sometimes referred to as the "Shares." The
Shares are described in the Prospectus which is referred to below.

          The Company has prepared and filed, in accordance with the provisions
of the Securities Act of 1933, as amended, and the rules and regulations
thereunder (collectively, the "Act"), with the Securities and Exchange
Commission (the "Commission") a registration statement on Form S-1 (File No.
333-134088) under the Act, including a prospectus, relating to the Shares.

          Except where the context otherwise requires, "Registration Statement,"
as used herein, means the registration statement, as amended at the time of such
registration statement's effectiveness for purposes of Section 11 of the Act, as
such section applies to the respective Underwriters (the "Effective Time"),
including (i) all documents filed as a part thereof, (ii) any information
contained in a prospectus filed with the Commission pursuant to Rule 424(b)
under the Act, to the extent such information is deemed, pursuant to Rule 430A
or Rule 430C under the Act, to be part of the registration statement at the
Effective Time, and (iii) any registration statement filed to register the offer
and sale of Shares pursuant to Rule 462(b) under the Act.

          The Company has furnished to you, for use by the Underwriters and by
dealers in connection with the offering of the Shares, copies of one or more
preliminary prospectuses relating to the Shares. Except where the context
otherwise requires, "Preliminary Prospectus," as used herein, means each such
preliminary prospectus, in the form so furnished.



          Except where the context otherwise requires, "Prospectus," as used
herein, means the prospectus, relating to the Shares, filed by the Company with
the Commission pursuant to Rule 424(b) under the Act on or before the second
business day after the date hereof (or such earlier time as may be required
under the Act), or, if no such filing is required, the final prospectus included
in the Registration Statement at the time it became effective under the Act, in
each case in the form furnished by the Company to you for use by the
Underwriters and by dealers in connection with the offering of the Shares.

          "Permitted Free Writing Prospectuses," as used herein, means the
documents listed on Schedule D attached hereto and each "road show" (as defined
in Rule 433 under the Act), if any, related to the offering of the Shares
contemplated hereby that is a "written communication" (as defined in Rule 405
under the Act) (each such road show, an "Electronic Road Show"). The
Underwriters have not offered or sold and will not offer or sell, without the
Company's consent, any Shares by means of any "free writing prospectus" (as
defined in Rule 405 under the Act) that is required to be filed by the
Underwriters with the Commission pursuant to Rule 433 under the Act, other than
a Permitted Free Writing Prospectus.

          "Disclosure Package," as used herein, means any Preliminary Prospectus
together with any combination of one or more of the Permitted Free Writing
Prospectuses, if any.

          As used in this Agreement, "Business Day" shall mean a day on which
the NASDAQ Stock Market LLC Global Market (the "NASDAQ") is open for trading.
The terms "herein," "hereof," "hereto," "hereinafter" and similar terms, as used
in this Agreement, shall in each case refer to this Agreement as a whole and not
to any particular section, paragraph, sentence or other subdivision of this
Agreement. The term "or," as used herein, is not exclusive.

          The Company has prepared and filed, in accordance with Section 12 of
the Securities Exchange Act of 1934, as amended, and the rules and regulations
thereunder (collectively, the "Exchange Act"), a registration statement (as
amended, the "Exchange Act Registration Statement") on Form 8-A (File No.
1-[____]) under the Exchange Act to register, under Section 12(b) of the
Exchange Act, the class of securities consisting of the Common Stock.

          The Company, each of the Selling Stockholders and the Underwriters
agree as follows:

     1. Sale and Purchase. Upon the basis of the representations and warranties,
and subject to the terms and conditions herein set forth, the Company agrees to
issue and sell and each of the Selling Stockholders agrees to sell, in each case
severally and not jointly, to the respective Underwriters and each of the
Underwriters, severally and not jointly, agrees to purchase from the Company and
each Selling Stockholder, the respective number of Firm Shares (subject to such
adjustment as UBS Securities LLC ("UBS") may determine to avoid fractional
shares) which bears the same proportion to the total number of Firm Shares to be
sold by the Company or by such Selling Stockholder, as the case may be, as the
number of Firm Shares set forth opposite the name of such Underwriter in
Schedule A annexed hereto, subject to adjustment in accordance with Section 11
hereof, bears to the total number of Firm Shares, in each case at a purchase
price of $[____] per Share. The Company is advised by you that the


                                      -2-



Underwriters intend (i) to make a public offering of their respective portions
of the Firm Shares as soon after the effective date of the Registration
Statement as in your judgment is advisable and (ii) initially to offer the Firm
Shares upon the terms set forth in the Prospectus. You may from time to time
increase or decrease the public offering price after the initial public offering
to such extent as you may determine; provided, however, that any such increase
or decrease shall not affect the purchase price for the Shares that is payable
to the Company by the Underwriters pursuant to this Agreement.

          In addition, the Company hereby grants to the several Underwriters the
option (the "Over-Allotment Option") to purchase, and upon the basis of the
representations and warranties and subject to the terms and conditions herein
set forth, the Underwriters shall have the right to purchase from the Company
all or a portion of the Additional Shares as may be necessary to cover
over-allotments made in connection with the offering of the Firm Shares, at the
same purchase price per share to be paid by the Underwriters to the Company and
the Selling Stockholders for the Firm Shares. The Over-Allotment Option may be
exercised by UBS on behalf of the several Underwriters at any time, and from
time to time, on or before the thirtieth day following the date of the
Prospectus, by written notice to the Company. Such notice shall set forth the
aggregate number of Additional Shares as to which the Over-Allotment Option is
being exercised, and the date and time when the Additional Shares are to be
delivered (any such date and time being herein referred to as an "additional
time of purchase"); provided, however, that no additional time of purchase shall
be earlier than the "time of purchase" (as defined below) nor earlier than the
second Business Day after the date on which the Over-Allotment Option shall have
been exercised nor later than the tenth Business Day after the date on which the
Over-Allotment Option shall have been exercised. The number of Additional Shares
to be sold to each Underwriter shall be the number which bears the same
proportion to the aggregate number of Additional Shares being purchased as the
number of Firm Shares set forth opposite the name of such Underwriter on
Schedule A hereto bears to the total number of Firm Shares (subject, in each
case, to such adjustment as UBS may determine to eliminate fractional shares),
subject to adjustment in accordance with Section 11 hereof.

          Pursuant to powers of attorney (the "Powers of Attorney") granted by
each Selling Stockholder (which Powers of Attorney shall be satisfactory to
UBS), [             ] shall act as representative of the Selling Stockholders
(the "Representative of the Selling Stockholders"). The Representative of the
Selling Stockholders is authorized, on behalf of each Selling Stockholder, among
other things, to execute any documents necessary or desirable in connection with
the sale of the Shares to be sold hereunder by such Selling Stockholder, to make
delivery of the certificates of such Shares, to receive the proceeds of the sale
of such Shares, to give receipts for such proceeds, to pay therefrom the
expenses to be borne by such Selling Stockholder in connection with the sale and
public offering of the Shares, to distribute the balance of such proceeds to
such Selling Stockholder, to receive notices on behalf of such Selling
Stockholder and to take such other action as may be necessary or desirable in
connection with the transactions contemplated by this Agreement.

     2. Payment and Delivery. Payment of the purchase price for the Firm Shares
shall be made to the Company and to each Selling Stockholder by Federal Funds
wire transfer, against delivery of the certificates for the Firm Shares to you
through the facilities of The Depository Trust Company ("DTC") for the
respective accounts of the Underwriters. Such payment and


                                      -3-



delivery shall be made at 10:00 A.M., New York City time, on November [__], 2006
(unless another time shall be agreed to by you and the Company and the
Representative of the Selling Stockholders or unless postponed in accordance
with the provisions of Section 11 hereof). The time at which such payment and
delivery are to be made is hereinafter sometimes called the "time of purchase."
Electronic transfer of the Firm Shares shall be made to you at the time of
purchase in such names and in such denominations as you shall specify.

          Payment of the purchase price for the Additional Shares shall be made
at the additional time of purchase in the same manner and at the same office as
the payment for the Firm Shares. Electronic transfer of the Additional Shares
shall be made to you at the additional time of purchase in such names and in
such denominations as you shall specify.

          Deliveries of the documents described in Section 9 hereof with respect
to the purchase of the Shares shall be made at the offices of Milbank, Tweed,
Hadley & McCloy LLP, One Chase Manhattan Plaza, New York, New York 10005, at

     Shares, in all material respects, with the requirements of the Act
     (including, without limitation, Section 10(a) of the Act); at no time

     or indirectly, prepared, used or referred to any Permitted Free Writing
     Prospectus except in compliance with Rules 164 and 433 under the Act;
     assuming that such Permitted Free Writing Prospectus is accompanied or
     preceded by the most recent Preliminary Prospectus that contains a price
     range or the Prospectus, as the case may be, and that such Permitted Free

     property of the Company; the Company has caused there to be made available
     at least one version of a "bona fide electronic road show" (as defined in
     Rule 433 under the Act) in a manner that, pursuant to Rule 433(d)(8)(ii)
     under the Act, causes the Company not to be required, pursuant to Rule
     433(d) under the Act, to file, with the Commission, any Electronic Road
     Show;

          (d) as of the date of this Agreement, the Company has the authorized

     the second and third sentences of the second paragraph under the heading
     "Risk factors--We have material weaknesses and significant deficiencies in
     our internal control over financial reporting" on page [13] of the
     Preliminary Prospectus and the Prospectus included in the Registration
     Statement, transactions are executed in accordance with management's
     general or specific authorization; (2) transactions are recorded as
     necessary to permit preparation of financial statements in conformity with
     GAAP and to maintain accountability for assets; (3) access to assets is
     permitted only in accordance with management's general or specific
     authorization; and (4) the recorded accountability for assets is compared

     "disclosure controls and procedures" (as such term is defined in Rule
     13a-15 and 15d-15 under the Exchange Act); such disclosure controls and
     procedures are designed to ensure that material information relating to the
     Company, including its consolidated subsidiaries, is made known to the
     Company's Chief Executive Officer and its Chief Financial Officer by others
     within those entities, and such disclosure controls and procedures are
     effective to perform the functions for which they were established; the
     Company's independent auditors and the Audit Committee of the Board of
     Directors of the Company have been advised of (i) all significant
     deficiencies and material weaknesses in the design or operation of internal
     control over financial reporting which could adversely affect the Company's
     ability to record, process, summarize, and report financial data and (ii)
     any fraud, whether or not material, that involves management or other
     employees who have a significant role in the Company's internal control
     over financial reporting; since the date of the most recent evaluation of
     such disclosure controls and procedures, except as described in the
     Registration Statement, the Preliminary Prospectus and the Prospectus,
     there have been no significant changes in internal control over financial
     reporting or in other factors that could significantly affect internal
     control over financial reporting, including any corrective actions with
     regard to significant deficiencies and material weaknesses; and the Company
     has taken or will take all necessary actions to ensure that the Company and
     the Subsidiaries and their respective officers and directors, in their
     capacities as such, will be in compliance in all material respects with all
     applicable and effective provisions of the Sarbanes-Oxley Act of 2002 and

(E) any other calamity or crisis or any change in financial, political or
economic conditions in the United States or elsewhere, if the effect of any such
event specified in clause (D) or (E), in the sole judgment of UBS, makes it
impractical or inadvisable to proceed with the public offering or the delivery
of the Shares on the terms and in the manner contemplated in the Registration
Statement, the Preliminary Prospectuses, the Prospectus and the Permitted Free
Writing Prospectuses, if any, or (3) since the time of execution of this
Agreement, there shall have occurred any downgrading, or any notice or
announcement shall have been given or made of: (A) any intended or potential
downgrading or (B) any watch, review or possible change that does not indicate
an affirmation or improvement in the rating accorded any securities of or
guaranteed by the Company or any Subsidiary by any "nationally recognized
statistical rating organization," as that term is defined in Rule 436(g)(2)
under the Act.

          If UBS elects to terminate this Agreement as provided in this Section
10, the Company, the Selling Stockholders and each other Underwriter shall be
notified promptly in writing.

          If the sale to the Underwriters of the Shares, as contemplated by this
Agreement, is not carried out by the Underwriters for any reason permitted under
this Agreement, or if such sale is not carried out because the Company or any
Selling Stockholder, as the case may be, shall be unable to comply with any of
the terms of this Agreement, the Company and the Selling Stockholders shall not
be under any obligation or liability under this Agreement (except to the extent
provided in Sections 7, 8 and 12 hereof), and the Underwriters shall be under no
obligation or liability to the Company or any Selling Stockholder under this
Agreement (except to the extent provided in Section 12 hereof) or to one another
hereunder.

     11. Increase in Underwriters' Commitments. Subject to Sections 9 and 10
hereof, if any Underwriter shall default in its obligation to take up and pay
for the Firm Shares to be purchased by it hereunder (otherwise than for a
failure of a condition set forth in Section 9 hereof or a reason sufficient to
justify the termination of this Agreement under the provisions of Section 10
hereof) and if the number of Firm Shares which all Underwriters so defaulting
shall have agreed but failed to take up and pay for does not exceed 10% of the
total number of Firm Shares, the non-defaulting Underwriters (including the
Underwriters, if any, substituted in the manner set forth below) shall take up
and pay for (in addition to the aggregate number of Firm Shares they are
obligated to purchase pursuant to Section 1 hereof) the number of Firm Shares
agreed to be purchased by all such defaulting Underwriters, as hereinafter
provided. Such Shares shall be taken up and paid for by such non-defaulting
Underwriters in such amount or amounts as you may designate with the consent of
each Underwriter so designated or, in the event no such designation is made,
such Shares shall be taken up and paid for by all non-defaulting Underwriters
pro rata in proportion to the aggregate number of Firm Shares set forth opposite
the names of such non-defaulting Underwriters in Schedule A.

          Without relieving any defaulting Underwriter from its obligations
hereunder, the Company and each Selling Stockholder each agree with the
non-defaulting Underwriters that they will not sell any Firm Shares hereunder
unless all of the Firm Shares are purchased by the


                                      -32-



Underwriters (or by substituted Underwriters selected by you with the approval
of the Company or selected by the Company with your approval).

          If a new Underwriter or Underwriters are substituted by the
Underwriters or by the Company for a defaulting Underwriter or Underwriters in
accordance with the foregoing provision, the Company or you shall have the right
to postpone the time of purchase for a period not exceeding five Business Days
in order that any necessary changes in the Registration Statement and the
Prospectus and other documents may be effected.

          The term "Underwriter" as used in this Agreement shall refer to and
include any Underwriter substituted under this Section 11 with like effect as if
such substituted Underwriter had originally been named in Schedule A hereto.

          If the aggregate number of Firm Shares which the defaulting
Underwriter or Underwriters agreed to purchase exceeds 10% of the total number
of Firm Shares which all Underwriters agreed to purchase hereunder, and if
neither the non-defaulting Underwriters nor the Company shall make arrangements
within the five Business Day period stated above for the purchase of all the
Firm Shares which the defaulting Underwriter or Underwriters agreed to purchase
hereunder, this Agreement shall terminate without further act or deed and
without any liability on the part of the Company or any Selling Stockholder to
any non-defaulting Underwriter and without any liability on the part of any
non-defaulting Underwriter to the Company or to any Selling Stockholder;
provided, however, that, for avoidance of doubt, in the case of such a
termination on account of a default with respect to any Additional Shares, this
Agreement shall not terminate as to the Firm Shares or any Additional Shares
purchased by the Underwriters from the Company or the Selling Stockholders
pursuant to this Agreement prior to such termination. Nothing in this paragraph,
and no action taken hereunder, shall relieve any defaulting Underwriter from
liability in respect of any default of such Underwriter under this Agreement.

     12. Indemnity and Contribution.

          (a) The Company agrees to indemnify, defend and hold harmless each
     Underwriter, its partners, directors and officers, and any person who
     controls any Underwriter within the meaning of Section 15 of the Act or
     Section 20 of the Exchange Act, and the successors and assigns of all of
     the foregoing persons, from and against any loss, damage, expense,
     liability or claim (including the reasonable cost of investigation) which,
     jointly or severally, any such Underwriter or any such person may incur
     under the Act, the Exchange Act, the common law or otherwise, insofar as
     such loss, damage, expense, liability or claim arises out of or is based
     upon (i) any untrue statement or alleged untrue statement of a material
     fact contained in the Registration Statement (or in the Registration
     Statement as amended by any post-effective amendment thereof by the
     Company) or arises out of or is based upon any omission or alleged omission
     to state a material fact required to be stated therein or necessary to make
     the statements therein not misleading, except insofar as any such loss,
     damage, expense, liability or claim arises out of or is based upon any
     untrue statement or alleged untrue statement of a material fact contained
     in, and in conformity with information concerning such Underwriter
     furnished in writing by or on behalf of such Underwriter through UBS to the
     Company expressly


                                      -33-



     for use in, the Registration Statement or arises out of or is based upon
     any omission or alleged omission to state a material fact in the
     Registration Statement in connection with such information, which material
     fact was not contained in such information and which material fact was
     required to be stated in such Registration Statement or was necessary to
     make such information not misleading, or (ii) any untrue statement or
     alleged untrue statement of a material fact included in any Prospectus (the
     term Prospectus for the purpose of this Section 12 being deemed to include
     any Preliminary Prospectus, the Prospectus and any amendments or
     supplements to the foregoing), in any Permitted Free Writing Prospectus, in
     any "issuer information" (as defined in Rule 433 under the Act) of the
     Company, which "issuer information" is required to be, or is, filed with
     the Commission, or in any Prospectus together with any combination of one
     or more of the Permitted Free Writing Prospectuses, if any, or arises out
     of or is based upon any omission or alleged omission to state a material
     fact necessary in order to make the statements therein, in the light of the
     circumstances under which they were made, not misleading, except, with
     respect to such Prospectus or Permitted Free Writing Prospectus, insofar as
     any such loss, damage, expense, liability or claim arises out of or is
     based upon any untrue statement or alleged untrue statement of a material
     fact contained in, and in conformity with information concerning such
     Underwriters furnished in writing by or on behalf of such Underwriter
     through you to the Company expressly for use in, such Prospectus or
     Permitted Free Writing Prospectus or arises out of or is based upon any
     omission or alleged omission to state a material fact in such Prospectus or
     Permitted Free Writing Prospectus in connection with such information,
     which material fact was not contained in such information and which
     material fact was necessary in order to make the statements in such
     information, in the light of the circumstances under which they were made,
     not misleading.

          (b) Each Selling Stockholder agrees to indemnify, defend and hold
     harmless the Company, each Underwriter, their respective partners,
     directors and officers, and any person who controls the Company or any
     Underwriter within the meaning of Section 15 of the Act or Section 20 of
     the Exchange Act, and the successors and assigns of all of the foregoing
     persons, from and against any loss, damage, expense, liability or claim
     (including the reasonable cost of investigation) which, jointly or
     severally, any of the foregoing persons may incur under the Act, the
     Exchange Act, the common law or otherwise, insofar as such loss, damage,
     expense, liability or claim arises out of or is based upon (i) any untrue
     statement or alleged untrue statement of a material fact contained in the
     Registration Statement (or in the Registration Statement as amended by any
     post-effective amendment thereof by the Company), as such Registration
     Statement relates to such Selling Stockholder, or arises out of or is based
     upon any omission or alleged omission to state a material fact required to
     be stated therein or necessary to make the statements therein not
     misleading or (ii) any untrue statement or alleged untrue statement of a
     material fact included in any Prospectus, in any Permitted Free Writing
     Prospectus or in any Prospectus together with any combination of one or
     more of the Permitted Free Writing Prospectuses, if any, in each case as
     such document(s) relate to such Selling Stockholder, or arises out of or is
     based upon any omission or alleged omission to state a material fact
     necessary in order to make the statements therein, in the light of the
     circumstances under which they were made, not misleading, in each of cases
     (i) and (ii) to the extent, but only to the extent, that such untrue
     statement or alleged


                                      -34-



     untrue statement or omission or alleged omission was made in reliance upon
     and in conformity with written information furnished to the Company by such
     Selling Stockholder expressly for use therein; provided, however, that no
     Selling Stockholder shall be responsible, pursuant to this Section 12(b),
     for losses, damages, expenses, liabilities or claims for an amount in
     excess of the aggregate initial public offering price of the Shares sold by
     such Selling Stockholder to the Underwriters pursuant hereto.
     Notwithstanding anything herein to the contrary, in no event shall the
     liability of any Selling Stockholder to provide indemnity pursuant to this
     Section 12(b), or contribution pursuant to Section 12(e), exceed an amount
     equal to the aggregate initial public offering price of the Shares sold by
     such Selling Stockholder to the Underwriters pursuant hereto.

          (c) Each Underwriter severally agrees to indemnify, defend and hold
     harmless the Company, its directors and officers, each Selling Stockholder
     and any person who controls the Company within the meaning of Section 15 of
     the Act or Section 20 of the Exchange Act, and the successors and assigns
     of all of the foregoing persons, from and against any loss, damage,
     expense, liability or claim (including the reasonable cost of
     investigation) which, jointly or severally, the Company, such Selling
     Stockholder or any such person may incur under the Act, the Exchange Act,
     the common law or otherwise, insofar as such loss, damage, expense,
     liability or claim arises out of or is based upon (i) any untrue statement
     or alleged untrue statement of a material fact contained in, and in
     conformity with information concerning such Underwriter furnished in
     writing by or on behalf of such Underwriter through you to the Company
     expressly for use in, the Registration Statement (or in the Registration
     Statement as amended by any post-effective amendment thereof by the
     Company), or arises out of or is based upon any omission or alleged
     omission to state a material fact in such Registration Statement in
     connection with such information, which material fact was not contained in
     such information and which material fact was required to be stated in such
     Registration Statement or was necessary to make such information not
     misleading or (ii) any untrue statement or alleged untrue statement of a
     material fact contained in, and in conformity with information concerning
     such Underwriter furnished in writing by or on behalf of such Underwriter
     through you to the Company expressly for use in, a Prospectus or a
     Permitted Free Writing Prospectus, or arises out of or is based upon any
     omission or alleged omission to state a material fact in such Prospectus or
     Permitted Free Writing Prospectus in connection with such information,
     which material fact was not contained in such information and which
     material fact was necessary in order to make the statements in such
     information, in the light of the circumstances under which they were made,
     not misleading.

          (d) If any action, suit or proceeding (each, a "Proceeding") is
     brought against a person (an "indemnified party") in respect of which
     indemnity may be sought against the Company, a Selling Stockholder or an
     Underwriter (as applicable, the "indemnifying party") pursuant to
     subsection (a), (b) or (c), respectively, of this Section 12, such
     indemnified party shall promptly notify such indemnifying party in writing
     of the institution of such Proceeding and such indemnifying party shall
     assume the defense of such Proceeding, including the employment of counsel
     reasonably satisfactory to such indemnified party and payment of all fees
     and expenses; provided, however, that the omission to so notify such
     indemnifying party shall not relieve such indemnifying party


                                      -35-



     from any liability which such indemnifying party may have to any
     indemnified party or otherwise, except to the extent that the indemnifying
     party has been prejudiced in any material respect by such failure through
     the forfeiture of substantive rights or defenses. The indemnified party or
     parties shall have the right to employ its or their own counsel in any such
     case, but the fees and expenses of such counsel shall be at the expense of
     such indemnified party or parties unless the employment of such counsel
     shall have been authorized in writing by the indemnifying party (or, in the
     case such indemnifying party is a Selling Stockholder, by such Selling
     Stockholder or by the Representative of the Selling Stockholders) in
     connection with the defense of such Proceeding or the indemnifying party
     shall not have, within a reasonable period of time in light of the
     circumstances, employed counsel to defend such Proceeding or such
     indemnified party or parties shall have reasonably concluded that there may
     be defenses available to it or them which are different from, additional to
     or in conflict with those available to such indemnifying party (in which
     case such indemnifying party shall not have the right to direct the defense
     of such Proceeding on behalf of the indemnified party or parties), in any
     of which events such fees and expenses shall be borne by such indemnifying
     party and paid as incurred (it being understood, however, that such
     indemnifying party shall not be liable for the expenses of more than one
     separate counsel (in addition to any local counsel) in any one Proceeding
     or series of related Proceedings in the same jurisdiction representing the
     indemnified parties who are parties to such Proceeding). The indemnifying
     party shall not be liable for any settlement of any Proceeding effected
     without its written consent (or, in the case such indemnifying party is a
     Selling Stockholder, without the written consent of either such Selling
     Stockholder or the Representative of the Selling Stockholders) but, if
     settled with its written consent (or, in the case such indemnifying party
     is a Selling Stockholder, with the written consent of such Selling
     Stockholder or of the Representative of the Selling Stockholders), such
     indemnifying party agrees to indemnify and hold harmless the indemnified
     party or parties from and against any loss or liability by reason of such
     settlement. Notwithstanding the foregoing sentence, if at any time an
     indemnified party shall have requested an indemnifying party (or, where
     such indemnifying party is a Selling Stockholder, requested such Selling
     Stockholder or the Representative of the Selling Stockholders) to reimburse
     the indemnified party for fees and expenses of counsel as contemplated by
     the second sentence of this Section 12(d), then the indemnifying party
     agrees that it shall be liable for any settlement of any Proceeding
     effected without its written consent if (i) such settlement is entered into
     more than 90 Business Days after receipt by such indemnifying party (or,
     where such indemnifying party is a Selling Stockholder, receipt by such
     Selling Stockholder or by the Representative of the Selling Stockholders)
     of the aforesaid request, (ii) such indemnifying party shall not have fully
     reimbursed the indemnified party in accordance with such request prior to
     the date of such settlement, unless there is a bona fide dispute between
     such indemnifying party and indemnified party regarding such reimbursement
     of such fees and expenses and the indemnifying party shall have fully
     reimbursed the indemnified party for the undisputed fees and expenses, and
     (iii) such indemnified party shall have given the indemnifying party (or,
     where such indemnifying party is a Selling Stockholder, given such Selling
     Stockholder or the Representative of the Selling Stockholders) at least 45
     days' prior notice of its intention to settle. No indemnifying party shall,
     without the prior written


                                      -36-



     consent of the indemnified party (or, where such indemnified party is a
     Selling Stockholder, the prior written consent of such Selling Stockholder
     or of the Representative of the Selling Stockholders), effect any
     settlement of any pending or threatened Proceeding in respect of which any
     indemnified party is or could have been a party and indemnity could have
     been sought hereunder by such indemnified party, unless such settlement
     includes an unconditional release of such indemnified party from all
     liability on claims that are the subject matter of such Proceeding and does
     not include an admission of fault or culpability or a failure to act by or
     on behalf of such indemnified party.

          (e) If the indemnification provided for in this Section 12 is
     unavailable to an indemnified party under subsections (a), (b) and (c) of
     this Section 12 or insufficient to hold an indemnified party harmless in
     respect of any losses, damages, expenses, liabilities or claims referred to
     therein, then each applicable indemnifying party shall contribute to the
     amount paid or payable by such indemnified party as a result of such
     losses, damages, expenses, liabilities or claims (i) in such proportion as
     is appropriate to reflect the relative benefits received by the Company and
     the Selling Stockholders on the one hand and the Underwriters on the other
     hand from the offering of the Shares or (ii) if the allocation provided by
     clause (i) above is not permitted by applicable law, in such proportion as
     is appropriate to reflect not only the relative benefits referred to in
     clause (i) above but also the relative fault of the Company and the Selling
     Stockholders on the one hand and of the Underwriters on the other in
     connection with the statements or omissions which resulted in such losses,
     damages, expenses, liabilities or claims, as well as any other relevant
     equitable considerations. The relative benefits received by the Company and
     the Selling Stockholders on the one hand and the Underwriters on the other
     shall be deemed to be in the same respective proportions as the total
     proceeds from the offering (net of underwriting discounts and commissions
     but before deducting expenses) received by the Company and the Selling
     Stockholders, and the total underwriting discounts and commissions received
     by the Underwriters, bear to the aggregate public offering price of the
     Shares. The relative fault of the Company and the Selling Stockholders on
     the one hand and of the Underwriters on the other shall be determined by
     reference to, among other things, whether the untrue statement or alleged
     untrue statement of a material fact or omission or alleged omission relates
     to information supplied by the Company or the Selling Stockholders or by
     the Underwriters and the parties' relative intent, knowledge, access to
     information and opportunity to correct or prevent such statement or
     omission. The amount paid or payable by a party as a result of the losses,
     damages, expenses, liabilities and claims referred to in this subsection
     shall be deemed to include any legal or other fees or expenses reasonably
     incurred by such party in connection with investigating, preparing to
     defend or defending any Proceeding.

          (f) The Company, the Selling Stockholders and the Underwriters agree
     that it would not be just and equitable if contribution pursuant to this
     Section 12 were determined by pro rata allocation (even if the Underwriters
     were treated as one entity for such purpose) or by any other method of
     allocation that does not take account of the equitable considerations
     referred to in subsection (e) above. Notwithstanding the provisions of this
     Section 12, no Underwriter shall be required to contribute any amount in
     excess of the amount by which the total price at which the Shares
     underwritten by such


                                      -37-



     Underwriter and distributed to the public were offered to the public
     exceeds the amount of any damage which such Underwriter has otherwise been
     required to pay by reason of such untrue statement or alleged untrue
     statement or omission or alleged omission. No person guilty of fraudulent
     misrepresentation (within the meaning of Section 11(f) of the Act) shall be
     entitled to contribution from any person who was not guilty of such
     fraudulent misrepresentation. The Underwriters' obligations to contribute
     pursuant to this Section 12 are several in proportion to their respective
     underwriting commitments and not joint.

          (g) The indemnity and contribution agreements contained in this
     Section 12 and the covenants, warranties and representations of the Company
     and the Selling Stockholders contained in this Agreement shall remain in
     full force and effect regardless of any investigation made by or on behalf
     of any Underwriter, its partners, directors or officers or any person
     (including each partner, officer or director of such person) who controls
     any Underwriter within the meaning of Section 15 of the Act or Section 20
     of the Exchange Act, or by or on behalf of the Company or the Selling
     Stockholders, their respective directors or officers or any person who
     controls the Company or any Selling Stockholder within the meaning of
     Section 15 of the Act or Section 20 of the Exchange Act, and shall survive
     any termination of this Agreement or the issuance and delivery of the
     Shares to be sold by the Company pursuant hereto and the delivery of the
     Shares to be sold by the Selling Stockholders pursuant hereto. The Company,
     the Selling Stockholders and each Underwriter agree promptly to notify each
     other of the commencement of any Proceeding against it and, in the case of
     the Company or a Selling Stockholder, against any of their respective
     officers or directors in connection with the issuance and sale of the
     Shares, or in connection with the Registration Statement, any Preliminary
     Prospectus, the Prospectus or any Permitted Free Writing Prospectus.

     13. Information Furnished by the Underwriters. The statements set forth in
the last paragraph on the cover page of the Prospectus and the statements set
forth under the caption (1) ["Underwriting--Commissions and Discounts" regarding
the amount of selling concession and reallowance and (2) "--Price Stabilization,
Short Positions" in the Prospectus, only insofar as such statements relate to
the amount of selling concession and reallowance or to over-allotment and
stabilization activities that may be undertaken by the Underwriters], constitute
the only information furnished by or on behalf of the Underwriters as such
information is referred to in Sections 3, 4 and 12 hereof.

     14. Notices. Except as otherwise herein provided, all statements, requests,
notices and agreements shall be in writing or by telegram or facsimile and, if
to the Underwriters, shall be sufficient in all respects if delivered or sent to
UBS Securities LLC, 299 Park Avenue, New York, New York 10171-0026, Attention:
Syndicate Department and, if to the Company, shall be sufficient in all respects
if delivered or sent to the Company at the offices of the Company at ORBCOMM
Inc., 2115 Linwood Ave., Suite 100, Fort Lee, New Jersey 07024, Attention: Jerry
Eisenberg, President and Chief Executive Officer, and, if to any Selling

Representative of the Selling Stockholders at ORBCOMM Inc., 2115 Linwood Ave.,
Suite 100, Fort Lee, New Jersey 07024, Attention: [             ].


                                      -38-



     15. Governing Law; Construction. This Agreement and any claim, counterclaim
or dispute of any kind or nature whatsoever arising out of or in any way
relating to this Agreement ("Claim"), directly or indirectly, shall be governed
by, and construed in accordance with, the internal laws of the State of New
York. The section headings in this Agreement have been inserted as a matter of
convenience of reference and are not a part of this Agreement.

     16. Submission to Jurisdiction. Except as set forth below, no Claim may be
commenced, prosecuted or continued in any court other than the courts of the
State of New York located in the City and County of New York or in the United
States District Court for the Southern District of New York, which courts shall
have jurisdiction over the adjudication of such matters, and the Company, the
Selling Stockholders and the Underwriters each consent to the jurisdiction of
such courts and personal service with respect thereto. Each Underwriter and the
Company (on its behalf and, to the extent permitted by applicable law, on behalf
of its stockholders and affiliates) and each Selling Stockholder (on its behalf
and, in the case such Selling Stockholder is not an individual, to the extent
permitted by applicable law, on behalf of its stockholders) each waive all right
to trial by jury in any action, proceeding or counterclaim (whether based upon
contract, tort or otherwise) in any way arising out of or relating to this
Agreement. The Company, the Selling Stockholders and the Underwriters each agree
that a final judgment in any such action, proceeding or counterclaim brought in
any such court shall be conclusive and binding upon the Company, each Selling
Stockholder and the Underwriters and may be enforced in any other courts to the
jurisdiction of which the Company, any Selling Stockholder or any Underwriter is
or may be subject, by suit upon such judgment.

     17. Parties at Interest. The Agreement herein set forth has been and is
made solely for the benefit of the Underwriters and the Company and the Selling
Stockholders and to the extent provided in Section 12 hereof the controlling
persons, partners, directors and officers referred to in such section, and their
respective successors, assigns, heirs, personal representatives and executors
and administrators. No other person, partnership, association or corporation
(including a purchaser, as such purchaser, from any of the Underwriters) shall
acquire or have any right under or by virtue of this Agreement.

     18. No Fiduciary Relationship. The Company and the Selling Stockholders
each hereby acknowledge that the Underwriters are acting solely as underwriters
in connection with the purchase and sale of the Company's securities. The
Company and the Selling Stockholders each further acknowledge that the
Underwriters are acting pursuant to a contractual relationship created solely by
this Agreement entered into on an arm's length basis, and in no event do the
parties intend that the Underwriters act or be responsible as a fiduciary to the
Company or any Selling Stockholder, their respective management, stockholders or
creditors or any other person in connection with any activity that the
Underwriters may undertake or have undertaken in furtherance of the purchase and
sale of the Company's securities, either before or after the date hereof. The
Underwriters hereby expressly disclaim any fiduciary or similar obligations to
the Company or any Selling Stockholder, either in connection with the
transactions contemplated by this Agreement or any matters leading up to such
transactions, and the Company and the Selling Stockholders each hereby confirm
their understanding and agreement to that effect. The Company, the Selling
Stockholders and the Underwriters agree that they are each responsible for

UBS Securities LLC
Together with the other Underwriters
Named in Schedule A to the Underwriting Agreement
Referred to herein

c/o UBS Securities LLC
299 Park Avenue
New York, New York 10171-0026

Ladies and Gentlemen:

          This Lock-Up Agreement is being delivered to you in connection with
the proposed Underwriting Agreement (the "Underwriting Agreement") to be entered
into by ORBCOMM Inc., a Delaware corporation (the "Company"), the Selling
Stockholders named therein, you and the other underwriters named in Schedule A
to the Underwriting Agreement (the "Underwriters"), with respect to the public
offering (the "Offering") of common stock, par value $0.001 per share, of the
Company (the "Common Stock").

          In order to induce you to enter into the Underwriting Agreement, the
undersigned agrees that, for a period (the "Lock-Up Period") beginning on the
date hereof and ending on, and including, the date that is 180 days after the
date of the final prospectus relating to the Offering, the undersigned will not,
without the prior written consent of UBS Securities LLC and the Company, (i)
sell, offer to sell, contract or agree to sell, hypothecate, pledge, grant any
option to purchase or otherwise dispose of or agree to dispose of, directly or
indirectly, or file (or participate in the filing of) a registration statement
with the Securities and Exchange Commission (the "Commission") in respect of, or
establish or increase a put equivalent position or liquidate or decrease a call
equivalent position within the meaning of Section 16 of the Securities Exchange
Act of 1934, as amended, and the rules and regulations of the Commission
promulgated thereunder (the "Exchange Act") with respect to, any Common Stock or
any other securities of the Company that are substantially similar to Common
Stock, or any securities convertible into or exchangeable or exercisable for, or
any warrants or other rights to purchase the foregoing (collectively, the
"Company Securities"), (ii) enter into any swap or other arrangement that
transfers to another, in whole or in part, any of the economic consequences of
ownership of Company Securities, whether any such transaction is to be settled
by delivery of Common Stock or such other securities, in cash or otherwise or
(iii) publicly announce an


                                      A-1



intention to effect any transaction specified in clause (i) or (ii). In the
event UBS Securities LLC and the Company consent to release any holder of
Company Securities (a "Released Stockholder") from any restrictions similar to
those set forth in this Lock-Up Agreement, the undersigned shall be similarly
released from this Lock-Up Agreement with respect to the percentage of
securities that is equal to the percentage of securities as to which such
Released Stockholder was released (as determined by dividing the number of
securities released by the aggregate number of securities held by such Released
Stockholder on a fully-diluted basis); provided, however, that the undersigned
shall not be so released from the restrictions set forth in this Lock-Up
Agreement, if holders of Company Securities owning a majority of the Company
Securities (which majority must include PCG Satellite Investments LLC) subject
to lock-up agreements with restrictions similar to those in this Lock-Up
Agreement shall have consented in writing to the release of the Released
Stockholder. The foregoing sentence shall not apply to (a) the registration of
the offer and sale of Common Stock as contemplated by the Underwriting Agreement
and the sale of Common Stock to the Underwriters (as defined in the Underwriting
Agreement) in the Offering, (b) bona fide gifts, (c) dispositions to any trust
for the direct or indirect benefit of the undersigned and/or the immediate
family of the undersigned, (d) distributions to partners, members, shareholders
or affiliates of the undersigned (and to any direct or indirect partner, member,
shareholders or affiliates thereof), (e) the exercise of options or warrants
(including a cashless exercise) or conversion of convertible securities
outstanding on the date hereof, provided that the Common Stock received upon
such exercise or conversion shall be subject to the Terms of this Lock-Up
Agreement, (f) transfers of Common Stock or other securities convertible into or
exchangeable or exercisable for Common Stock by will or intestate succession,
(g) a bona fide pledge of Common Stock, made in the ordinary course of business,
for the sole purpose of obtaining financing for the undersigned or (h)
transactions relating to Common Stock or other securities convertible into or
exchangeable or exercisable for Common Stock acquired in open market
transactions after completion of the Offering, provided no filing is required to
be made with the Commission related to such transaction; provided that in the
case of any gift, disposition, transfer, or pledge pursuant to clause (b), (c),
(d), (f) or (g), such donee, trust, distributee, transferee, pledgee or other
recipient of such Common Stock or securities convertible into or exchangeable or
exercisable for Common Stock agrees in writing with the Underwriters to be bound
by the terms of this Lock-Up Agreement. For purposes of this paragraph,
"immediate family" shall mean the undersigned and the spouse, any lineal
descendent, father, mother, brother or sister of the undersigned.

          Notwithstanding anything herein to the contrary, the restrictions in
the preceding paragraph shall not apply to the sale of Firm Shares or Additional
Shares by any Selling Stockholder to the Underwriters pursuant to the
Underwriting Agreement.

          In addition, the undersigned hereby waives any rights the undersigned
may have to require registration of Common Stock in connection with the filing
of a registration statement relating to the Offering. The undersigned further
agrees that, for the Lock-Up Period, the undersigned will not, without the prior
written consent of UBS Securities LLC, make any demand for, or exercise any
right with respect to, the registration of Common Stock or any securities
convertible into or exercisable or exchangeable for Common Stock, or warrants or
other rights to purchase Common Stock or any such securities.


                                      A-2



          Notwithstanding the above, if (a) during the period that begins on the
date that is fifteen (15) calendar days plus three (3) Business Days before the
last day of the Lock-Up Period and ends on the last day of the Lock-Up Period,
the Company issues an earnings release or material news or a material event
relating to the Company occurs; or (b) prior to the expiration of the Lock-Up
Period, the Company announces that it will release earnings results during the
sixteen (16) day period beginning on the last day of the Lock-Up Period, then
the restrictions imposed by this Lock-Up Agreement shall continue to apply until
the expiration of the date that is fifteen (15) calendar days plus three (3)
Business Days after the date on which the issuance of the earnings release or
the material news or material event occurs.

          In addition, the undersigned hereby waives any and all preemptive
rights, participation rights, resale rights, rights of first refusal and similar
rights that the undersigned may have solely in connection with the Offering or
with any issuance or sale by the Company of any equity or other securities prior
to the date of this Lock-Up Agreement, except for any such rights as have been
heretofore duly exercised.

          The undersigned hereby confirms that the undersigned has not, directly
or indirectly, taken, and hereby covenants that the undersigned will not,
directly or indirectly, take, any action designed, or which has constituted or
will constitute or might reasonably be expected to cause or result in, under the
Exchange Act or otherwise, the stabilization or manipulation of the price of any
security of the Company to facilitate the sale or resale of shares of Common
Stock.

                                      * * *


                                      A-3



          If (i) the Company notifies you in writing that it does not intend to
proceed with the Offering, (ii) the registration statement filed with the
Commission with respect to the Offering is withdrawn, (iii) for any reason the
Underwriting Agreement shall be terminated prior to the "time of purchase" (as
defined in the Underwriting Agreement) or (iv) the Offering is not consummated
prior to December 15, 2006, this Lock-Up Agreement shall be terminated and the
undersigned shall be released from its obligations hereunder.

                                        Yours very truly,
