Such notice shall set forth the aggregate number of Additional Shares as to which the option is being exercised and the date and time, as reasonably determined by you, when the Additional Shares are to be delivered (such date and time being herein sometimes referred to as the "Additional Closing Date"); provided, however, that the Additional Closing Date shall not be earlier than the Closing Date or earlier than the second full business day after the date on which the option shall have been exercised nor later than the eighth full business day after the date on which the option shall have been exercised (unless such time and date are postponed in accordance with the provisions of Section 9 hereof).

The Company will permit you to examine and package such certificates for delivery at least one full business day prior to the Additional Closing Date. The number of Additional Shares to be sold to each Underwriter shall be the number which bears the same ratio 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 I hereto (or such number increased as set forth in Section 9 hereof) bears to the total number of Firm Shares being purchased from the Company, subject, however, to such adjustments to eliminate any fractional shares as you in your sole discretion shall make. Payment for the Additional Shares shall be made by wire transfer in same day funds at the offices of Bear, Stearns & Co. Inc., or such other location as may be mutually acceptable, upon delivery of the certificates for the Additional Shares to you for the respective accounts of the Underwriters.

To the extent that such Directed Shares are not orally confirmed for purchase by such eligible employees of ORBCOMM and certain affiliates by the end of the first day of this Agreement, such Directed Shares may be offered to the public as part of the public offering contemplated hereby. Offers and sales of Directed Shares to eligible employees of ORBCOMM and certain affiliates in the Provinces of Quebec, British Columbia, Ontario or Nova Scotia, Canada will be effected by the Underwriters or their affiliates at the request of and as agent of the Company pursuant to prospectus exemptions available in Quebec, British Columbia, Ontario or Nova Scotia. 3.

(a) The Company and ORBCOMM, jointly and severally, agree to indemnify and hold harmless each Underwriter and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Act or Section 20(a) of the Exchange Act, against any and all losses, liabilities, claims, damages and expenses whatsoever as incurred (including but not limited to attorneys' fees and any and all expenses whatsoever incurred in investigating, preparing or defending against any litigation, commenced or threatened, or any claim whatsoever, and any and all amounts paid in settlement of any claim or litigation), joint or several, to which they or any of them may become subject under the Act, the Exchange Act or otherwise, insofar as such losses, liabilities, claims, damages or expenses (or actions in respect thereof) arise out of or are based upon any (i) untrue statement or alleged untrue statement of a material fact contained in the registration statement for the registration of the Shares, as originally filed or any amendment thereof, or any related preliminary prospectus or the Prospectus, or in any supplement thereto or amendment thereof, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, (ii) the violation of any applicable laws or regulations of foreign jurisdictions where Shares have been offered and (iii) any untrue statement or alleged untrue statement of a material fact included in the supplement or prospectus wrapper material distributed in connection with the reservation and sale of the Directed Shares to eligible employees of ORBCOMM and certain affiliates or otherwise or the omission or alleged omission therefrom of a material fact necessary to make the statements therein, when considered in conjunction with the Prospectus or preliminary prospectus, not misleading; provided, however, that the Company and ORBCOMM will not be liable in any such case to the extent but only to the extent that any such loss, liability, claim, damage or expense arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Company or ORBCOMM by or on behalf of any Underwriter through you expressly for use therein; and provided, further, that neither ORBCOMM nor the Company will be liable to an Underwriter with respect to any preliminary prospectus to the extent that ORBCOMM or the Company shall sustain the burden of proving that any such loss, liability, claim, damage or expense resulted from the fact that such Underwriter in contravention of a requirement of this Agreement or applicable law, sold Shares to a person to whom such Underwriter failed to send or give, at or prior to the Closing Date, a copy of the Prospectus as then amended or supplemented if the Company has previously furnished copies thereof (sufficiently in advance of the Closing Date to allow - 26 - 27 for distribution by the Closing Date) to the Underwriter and the loss, liability, claim, damage or expense of such Underwriter resulted from an untrue statement or omission or alleged untrue statement or omission of a material fact contained in or omitted from the preliminary prospectus which was corrected in the Prospectus as, if applicable, amended or supplemented prior to the Closing Date. This indemnity agreement will be in addition to any liability which the Company or ORBCOMM may otherwise have including under this Agreement. (b) Each Underwriter severally, and not jointly, agrees to indemnify and hold harmless the Company and ORBCOMM, each of the directors of the Company, each of the officers of the Company who shall have signed the Registration Statement, and each other person, if any, who controls the Company within the meaning of Section 15 of the Act or Section 20(a) of the Exchange Act, against any losses, liabilities, claims, damages and expenses whatsoever as incurred (including but not limited to attorneys' fees and any and all expenses whatsoever incurred in investigating, preparing or defending against any litigation, commenced or threatened, or any claim whatsoever, and any and all amounts paid in settlement of any claim or litigation), jointly or several, to which they or any of them may become subject under the Act, the Exchange Act or otherwise, insofar as such losses, liabilities, claims, damages or expenses (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of a material fact contained in the registration statement for the registration of the Shares, as originally filed or any amendment thereof, or any related preliminary prospectus or the Prospectus, or in any amendment thereof or supplement thereto, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that any such loss, liability, claim, damage or expense arises out of or is based upon any such untrue statement or alleged untrue statement or omission or alleged omission made therein in reliance upon and in conformity with written information furnished to the Company by or on behalf of any Underwriter through you expressly for use therein; provided, however, that in no case shall any Underwriter be liable or responsible for any amount in excess of the underwriting discount applicable to the Shares purchased by such Underwriter hereunder. This indemnity will be in addition to any liability which any Underwriter may otherwise have including under this Agreement. The Company and ORBCOMM each acknowledge that the statements set forth in the last paragraph of the cover page, the first paragraph of text on the inside front cover page of the Prospectus (regarding stabilization), and the third and eleventh paragraphs of text under the caption "Underwriting" in the Prospectus constitute the only information furnished in writing by or on behalf of any Underwriter expressly for use in the registration statement relating to the Shares as originally filed or in any amendment thereof, any related preliminary prospectus or the Prospectus or in any amendment thereof or supplement thereto, as the case may be. (c) Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify each party against whom indemnification is to be sought in writing of the commencement thereof (but the failure so to notify an indemnifying party shall not relieve it - 27 - 28 from any liability which it may have under this Section 7). In case any such action is brought against any indemnified party, and it notifies an indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein, and to the extent it may elect by written notice delivered to the indemnified party promptly after receiving the aforesaid notice from such indemnified party, to assume the defense thereof with counsel satisfactory to such indemnified party. Notwithstanding the foregoing, 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 (i) the employment of such counsel shall have been authorized in writing by one of the indemnifying parties in connection with the defense of such action, (ii) the indemnifying parties shall not have employed counsel to have charge of the defense of such action within a reasonable time after notice of commencement of the action, or (iii) such indemnified party or parties shall have reasonably concluded that there may be defenses available to it or them which are different from or additional to those available to one or all of the indemnifying parties (in which case the indemnifying parties shall not have the right to direct the defense of such action on behalf of the indemnified party or parties), in any of which events such fees and expenses shall be borne by the indemnifying parties; provided, however, that in connection with any one such action, or separate but substantially similar or related actions in the same jurisdiction arising out of the same general allegations or circumstances, the indemnifying parties shall be liable at any time only for the fees and expenses of any (A) one principal firm and (B) one local counsel in each jurisdiction in which it is deemed necessary to retain such local counsel for the indemnified parties unless, in either of (A) or (B) above, the representations of all indemnified parties by the same counsel would be inappropriate in light of actual or potential differing interests among them. Anything in this subsection to the contrary notwithstanding, an indemnifying party shall not be liable for any settlement of any claim or action effected without its written consent; provided, however, that such consent was not unreasonably withheld. (d) In connection with the offer and sale of the Directed Shares, each of the Company and ORBCOMM jointly and severally agrees, promptly upon a request in writing, to indemnify and hold harmless the Underwriters from and against any and all losses, liabilities, claims, damages and expenses incurred by them as a result of (i) the failure of eligible employees of ORBCOMM or its affiliates to pay for and accept delivery of Directed Shares which, following the effectiveness of the Registration Statement, were subject to a properly confirmed agreement to purchase and (ii) the violation of any securities laws of foreign jurisdictions in connection with any offer and/or sale of Directed Shares. 8. Contribution. In order to provide for contribution in circumstances in which the indemnification provided for in Section 7 hereof is for any reason held to be unavailable from any indemnifying party or is insufficient to hold harmless a party indemnified thereunder, the Company and ORBCOMM, on the one hand, and the Underwriters, on the other hand, shall contribute to the aggregate losses, claims, damages, liabilities and expenses of the nature contemplated by such indemnification provision (including any investigation, legal and other expenses incurred in connection with, and any amount paid in settlement of, any action, suit or proceeding or any claims asserted, but after - 28 - 29 deducting in the case of losses, claims, damages, liabilities and expenses suffered by the Company or ORBCOMM any contribution received by the Company or ORBCOMM from persons, other than the Underwriters, who may also be liable for contribution, including persons who control the Company or ORBCOMM within the meaning of Section 15 of the Act or Section 20(a) of the Exchange Act, officers of the Company who signed the Registration Statement and directors of the Company) as incurred to which the Company and ORBCOMM and one or more of the Underwriters may be subject, in such proportions as is appropriate to reflect the relative benefits received by the Company and ORBCOMM, on the one hand, and the Underwriters, on the other hand, from the offering of the Shares or, if such allocation is not permitted by applicable law or indemnification is not available as a result of the indemnifying party not having received notice as provided in Section 7 hereof, in such proportion as is appropriate to reflect not only the relative benefits referred to above but also the relative fault of the Company and ORBCOMM, on the one hand, and the Underwriters, on the other hand, in connection with the statements or omissions which resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative benefits received by the Company and ORBCOMM, on the one hand, and the Underwriters, on the other hand, shall be deemed to be in the same proportion as (x) the total proceeds from the offering (net of underwriting discounts and commissions but before deducting expenses) received by the Company and ORBCOMM and (y) the underwriting discounts and commissions received by the Underwriters, respectively, in each case as set forth in the table on the cover page of the Prospectus. The relative fault of the Company and ORBCOMM, on the one hand and of the Underwriters, on the other hand, 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 Company or ORBCOMM by the Underwriters and the parties' relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Company, ORBCOMM and the Underwriters agree that it would not be just and equitable if contribution pursuant to this Section 8 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 which does not take account of the equitable considerations referred to above. Notwithstanding the provisions of this Section 8, (i) in no case shall any Underwriter be liable or responsible for any amount in excess of the underwriting discount applicable to the Shares purchased by such Underwriter hereunder, and (ii) 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. Notwithstanding the provisions of this Section 8 and the preceding sentence, 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 it and distributed to the public were offered to the public exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. For purposes of this Section 8, each person, if any, who controls an Underwriter within the meaning of Section 15 of the Act or Section 20(a) of the Exchange Act shall have the same rights to contribution as such Underwriter, and each person, if any, who controls the Company or ORBCOMM within the meaning of Section 15 of the Act or Section 20(a) of the Exchange Act, each officer of the Company who shall have - 29 - 30 signed the Registration Statement and each director of the Company shall have the same rights to contribution as the Company and ORBCOMM, subject in each case to clauses (i) and (ii) of this Section 8. Any party entitled to contribution will, promptly after receipt of notice of commencement of any action, suit or proceeding against such party in respect of which a claim for contribution may be made against another party or parties, notify each party or parties from whom contribution may be sought, but the omission to so notify such party or parties shall not relieve the party or parties from whom contribution may be sought from any obligation it or they may have under this Section 8 or otherwise. No party shall be liable for contribution with respect to any action or claim settled without its consent; provided, however, that such consent was not unreasonably withheld. 9. Default by an Underwriter. (a) If any Underwriter or Underwriters shall default in its or their obligation to purchase Firm Shares or Additional Shares hereunder, and if the Firm Shares or Additional Shares with respect to which such default relates do not (after giving effect to arrangements, if any, made by you pursuant to subsection (b) below) exceed in the aggregate 10% of the number of Firm Shares or Additional Shares, to which the default relates shall be purchased by the non-defaulting Underwriters in proportion to the respective proportions which the numbers of Firm Shares set forth opposite their respective names in Schedule I hereto bear to the aggregate number of Firm Shares set forth opposite the names of the non-defaulting Underwriters. (b) In the event that such default relates to more than 10% of the Firm Shares or Additional Shares, as the case may be, you may in your discretion arrange for yourself or for another party or parties (including any non-defaulting Underwriter or Underwriters who so agree) to purchase such Firm Shares or Additional Shares, as the case may be, to which such default relates on the terms contained herein. In the event that within 5 calendar days after such a default you do not arrange for the purchase of the Firm Shares or Additional Shares, as the case may be, to which such default relates as provided in this Section 9, this Agreement or, in the case of a default with respect to the Additional Shares, the obligations of the Underwriters to purchase and of the Company to sell the Additional Shares shall thereupon terminate, without liability on the part of the Company with respect thereto (except in each case as provided in Section 5, 7(a) and 8 hereof) or the Underwriters, but nothing in this Agreement shall relieve a defaulting Underwriter or Underwriters of its or their liability, if any, to the other Underwriters and the Company for damages occasioned by its or their default hereunder. (c) In the event that the Firm Shares or Additional Shares to which the default relates are to be purchased by the non-defaulting Underwriters, or are to be purchased by another party or parties as aforesaid, you or the Company shall have the right to postpone the Closing Date or Additional Closing Date, as the case may be for a period, not exceeding five business days, in order to effect whatever changes may thereby be made necessary in the Registration Statement or the Prospectus or in any other documents and arrangements, and the Company agrees to file promptly any amendment or supplement to the Registration Statement or the Prospectus which, in the opinion of Underwriters' Counsel, may thereby be made necessary or advisable. The term "Underwriter" as used in this Agreement shall - 30 - 31 include any party substituted under this Section 9 with like effect as if it had originally been a party to this Agreement with respect to such Firm Shares and Additional Shares. 10. Survival of Representations and Agreements. All representations and warranties, covenants and agreements of the Underwriters, the Company and ORBCOMM contained in this Agreement, including the agreements contained in Section 5, the indemnity agreements contained in Section 7 and the contribution agreements contained in Section 8, shall remain operative and in full force and effect regardless of any investigation made by or on behalf of any Underwriter or any controlling person thereof or by or on behalf of the Company and ORBCOMM, any of its officers and directors or any controlling person thereof, and shall survive delivery of and payment for the Shares to and by the Underwriters. The representations contained in Section 1 and the agreements contained in Sections 5, 7, 8 and 11(d) hereof shall survive the termination of this Agreement, including termination pursuant to Section 9 or 11 hereof. 11. Effective Date of Agreement; Termination. (a) This Agreement shall become effective, upon the later of when (i) you and the Company shall have received notification of the effectiveness of the Registration Statement or (ii) the execution of this Agreement. If either the initial public offering price or the purchase price per Share has not been agreed upon prior to 5:00 P.M., New York time, on the fifth full business day after the Registration Statement shall have become effective, this Agreement shall thereupon terminate without liability to the Company or the Underwriters except as herein expressly provided. Until this Agreement becomes effective as aforesaid, it may be terminated by the Company by notifying you or by you notifying the Company. Notwithstanding the foregoing, the provisions of this Section 11 and of Sections 1, 5, 7 and 8 hereof shall at all times be in full force and effect. (b) You shall have the right to terminate this Agreement at any time prior to the Closing Date or the obligations of the Underwriters to purchase the Additional Shares at any time prior to the Additional Closing Date, as the case may be, if (i) any domestic or international event or act or occurrence has materially disrupted, or in your opinion will in the immediate future materially disrupt, the market for the Company's or ORBCOMM's securities or securities in general; or (ii) if trading on the New York or American Stock Exchanges or Nasdaq National Market shall have been suspended, or minimum or maximum prices for trading shall have been fixed, or maximum ranges for prices for securities shall have been required, on the New York or American Stock Exchanges or Nasdaq National Market by the New York or American Stock Exchanges or the National Association of Securities Dealers Automated Quotation System, Inc. or by order of the Commission or any other governmental authority having jurisdiction; or (iii) if a banking moratorium has been declared by a state or federal authority or if any new restriction materially adversely affecting the distribution of the Firm Shares or the Additional Shares, as the case may be, shall have become effective; or (iv) if any downgrading in the rating of ORBCOMM's debt securities by any "nationally recognized statistical rating-organization" (as defined for purposes of Rule 436(g) under the Act; or (v) (A) if the United States becomes engaged in hostilities or there is an escalation of hostilities involving the United States or there is a declaration of a - 31 - 32 national emergency or war by the United States or (B) if there shall have been such change in political, financial or economic conditions if the effect of any such event in (A) or (B) as in your judgment makes it impracticable or inadvisable to proceed with the offering, sale and delivery of the Firm Shares or the Additional Shares, as the case may be, on the terms contemplated by the Prospectus. (c) Any notice of termination pursuant to this Section 11 shall be by telephone, telex, or telegraph, confirmed in writing by letter. (d) If this Agreement shall be terminated pursuant to any of the provisions hereof (otherwise than pursuant to (i) notification by you as provided in Section 11(a) hereof or (ii) Section 9(b) or 11(b) hereof), or if the sale of the Shares provided for herein is not consummated because any condition to the obligations of the Underwriters set forth herein is not satisfied or because of any refusal, inability or failure on the part of the Company or ORBCOMM to perform any agreement herein or comply with any provision hereof, the Company and ORBCOMM jointly and severally will, subject to demand by you, reimburse the Underwriters for all out-of-pocket expenses (including the fees and expenses of their counsel), incurred by the Underwriters in connection herewith. 12.
