SECTION 2.03. LIMITATIONS ON EXCHANGE. (a) The Company shall be required to effect, or take any action to effect, any exchange of Partnership Units for Common Stock only to the extent that the sum of the number of Partnership Units requested to be exchanged pursuant to this Agreement (the "EXCHANGE UNITS") do not exceed the following amounts: (i) following the first fiscal quarter in which ORBCOMM has achieved positive earnings before interest, taxes, depreciation and amortization, as determined in accordance with generally accepted accounting principles, each Holder shall have the right, and the Company shall be required, to exchange up to 25% of such Holders' 4 6 Partnership Units (excluding, for the purpose of this calculation, any Partnership Units previously exchanged pursuant to this Section 2.03) for Common Stock; (ii) following the date on which ORBCOMM has launched a total of 28 satellites, each Holder shall have the right, and the Company shall be required, to exchange up to 25% of such Holders' Partnership Units (excluding, for the purpose of this calculation, any Partnership Units previously exchanged pursuant to this Section 2.03) for Common Stock; and (iii) following the earlier of: (A) the date on which ORBCOMM has launched a total of 36 satellites, provided that ORBCOMM has achieved positive earnings before interest, taxes, depreciation and amortization, as determined in accordance with generally accepted accounting principles for at least one full fiscal quarter; or (B) December 31, 2000, each Holder shall have the right, and the Company shall be required, to exchange up to 100% of such Holders' Partnership Units for Common Stock (such limitations from time to time, the "APPLICABLE LIMIT"). Each Holder may exchange up to 50% of such Holders' Partnership Units for Common Stock provided the conditions set forth in both clauses: (i) and (ii) of this Section 2.03(a) have been met. Notwithstanding the foregoing, each Holder is permitted to exchange up to 100% of such Holder's Partnership Units for Common Stock at any time, provided, that such exchange does not cause material adverse tax consequences for any other Holder (except if the effected Holder otherwise consents) and provided further, that shares of Common Stock received in exchange for Partnership Units pursuant to this sentence may not be registered pursuant to Article IV prior to the date such shares would have eligible for registration had they been received in an exchange conducted pursuant to the previous sentence. (b) If the Exchanging Holders request to exchange a number of Partnership Units in excess of the Applicable Limit, at the next meeting of the ORBCOMM Committee following the expiration of the Exchange Period, the ORBCOMM Committee shall determine whether to authorize the exchange of the Partnership Units in excess of the Applicable Limit requested to be exchanged pursuant to the Election Notices received during such Exchange Period. Authorization of the exchange of Partnership Units in excess of the Applicable Limit pursuant to this Section 2.03(b) shall require the affirmative vote of ORBCOMM Committee Members representing at least 66 2/3% of the ORBCOMM Committee Members, including at least one of the Independent Company Members. (c) Each Exchanging Holder shall have 10 Business Days from the last day of the Exchange Period to countersign and return to ORBCOMM the Notice of Exchange Authorization attached hereto as Exhibit C. Any Exchanging Holder that fails to so countersign and return its notice shall lose its exchange rights with respect to that Exchange Period. SECTION 2.04. EXCHANGE OF PARTNERSHIP UNITS. At the Closing described in Section 2.05, the Company shall issue and deliver to such Exchanging Holder shares of Common Stock in an amount equal to the Exchange Rate multiplied by the number of Exchange Units requested by a Holder in such Holders' Election Notice; provided, however, that number of Exchange Units shall not exceed the greater of: (a) the Applicable Limit or (b) the number of Partnership Units authorized for exchange by the ORBCOMM Committee pursuant to Section 2.03(b). SECTION 2.05. CLOSING. The closing of the transactions contemplated by this Article II shall take place at such specific time and place as shall be mutually agreed on by the Company, ORBCOMM and the Exchanging Holder(s) involved (the "CLOSING"). At the Closing, the Exchanging Holder(s) shall relinquish to the Company certificates representing such Partnership Units as are to be exchanged accompanied by such instruments of transfer as shall reasonably be required by the Company and ORBCOMM, and the Company shall deliver to such Exchanging Holder(s) shares of Common Stock in an amount determined pursuant to Section 2.04, registered in the name of such Exchanging Holder(s). The Company shall present to ORBCOMM such Partnership Units for transfer and ORBCOMM shall deliver replacement certificates representing the number of Partnership Units transferred to the Company in the name of the Company or its designee and ORBCOMM shall make corresponding notations in its books and records. In addition, each Exchanging Holder shall deliver to the Company and ORBCOMM 5 7 a letter of representation substantially in the form of Exhibit A attached hereto and such other certificates and documents as may reasonably be requested by the Company or ORBCOMM (including, without limitation, evidence of receipt of all required approvals and consents and compliance with all applicable securities and tax laws). No fractional interest in a share of Common Stock shall be issued by the Company on the exchange of Partnership Units. Any fractional interest in a share of Common Stock resulting from the exchange of any Partnership Units shall be paid by ORBCOMM in cash (computed to the nearest cent) based on the Closing Price of the Common Stock on the last Trading Day prior to the date on which such Partnership Units are surrendered for exchange in the manner set forth above. The Exchanging Holder will pay any and all documentary stamp or similar issue or transfer taxes payable in respect of the issue or delivery of shares of Common Stock on exchange of Partnership Units pursuant hereto, and the Company may withhold delivery until such charge is paid or offset against the number of shares to be delivered. SECTION 2.06. DISTRIBUTIONS WITH RESPECT TO PARTNERSHIP UNITS. Any payment or distribution (for purposes of this Section 2.06, a "distribution") received by an Exchanging Holder with respect to Partnership Units exchanged pursuant to this Article II by such Exchanging Holder allocable to any period after the Closing shall be forwarded immediately by the Exchanging Holder to the Company. ORBCOMM is hereby instructed to and agrees to pay or cause to be paid such portions of any distribution owed to the Company directly to the Company and thereafter shall be discharged of any obligation to such Exchanging Holder with respect to such portion of such distribution. SECTION 2.07. RESTRICTED SECURITIES. Any Common Stock issued by the Company to any Holder prior to the effectiveness of a registration statement filed with the Commission pursuant to Article IV below shall be "restricted securities" and any Holder receiving such "restricted securities" by execution and delivery of an Election Notice shall, at the time of issuance of such securities, execute and deliver a certificate in the form of Exhibit B attached hereto. The certificates evidencing such "restricted securities" shall bear a restrictive legend to the effect that the shares of Common Stock represented thereby have not been registered under the Securities Act, and may not be sold except pursuant to an effective registration statement under the Securities Act or pursuant to an applicable exemption from the registration requirements thereof. SECTION 2.08. SALE BY HOLDER. Each Holder, by execution and delivery of an Election Notice, shall be deemed to have agreed that it will not, directly or indirectly, transfer, sell, assign, pledge, hypothecate, encumber or otherwise dispose of, to any person, in one or a series of transactions, any shares of Common Stock received pursuant to this Agreement, except pursuant to an effective registration statement or an applicable exemption from the registration requirements of the Securities Act. SECTION 2.09. COMPANY COVENANTS. The Company covenants that: (a) all shares of Common Stock that may be issued on exchange of Partnership Units will, on issue, be duly and validly issued, fully paid and non-assessable (no further sums will be required to be paid by the holders of the shares in connection with the issue of such shares), free of all liens and charges and not subject to any preemptive rights; and (b) it will at all times reserve and keep available, free from preemptive rights, out of the aggregate of its authorized but unissued shares of Common Stock, for the purpose of effecting the exchange of Partnership Units hereunder, the full number of shares of Common Stock deliverable on the exchange of all outstanding Partnership Units not theretofore converted. SECTION 2.10. EXCHANGE DEFERRAL RIGHTS. At any time prior to the Closing either ORBCOMM or the Company shall have the right to defer an exchange hereunder for a period of up to 90 6 8 days if either ORBCOMM or the Company, as the case may be, determines that such a deferral is in the best interests of ORBCOMM or the Company, as the case may be, in light of possible or pending financing or other transactions. Such a deferral shall be effected by the furnishing by ORBCOMM or the Company to the Exchanging Holders of a written notice of an executive officer of ORBCOMM or the Company, as the case may be, stating that: (a) the Holders' right to exchange Partnership Units for Common Stock pursuant to this Agreement is deferred for a period of time; (b) the number of days, up to 90, of such deferral; and (c) that such deferral is being implemented pursuant to this Section 2.10. This right may not be utilized by either ORBCOMM or the Company more than once in any twelve month period. ARTICLE III. EXCHANGE DATE AND EXCHANGE RATE ADJUSTMENTS SECTION 3.01. EXCHANGE RATE ADJUSTMENTS -- COMPANY ACTIONS. The Exchange Rate shall be adjusted from time to time as follows: (a) In case the Company shall pay or make a dividend or other distribution on any class of capital stock of the Company in Common Stock, the Exchange Rate in effect at the opening of business on the day following the date fixed for the determination of stockholders entitled to receive such dividend or other distribution shall be adjusted by multiplying such Exchange Rate by a fraction the numerator of which shall be the sum of the number of shares of Common Stock outstanding at the close of business on the date fixed for such determination plus the total number of shares constituting such dividend or other distribution and the denominator of which shall be such number of shares of Common Stock outstanding at the close of business on the date fixed for such determination. The adjusted Exchange Rate shall be effective immediately after the opening of business on the day following the date fixed for such determination. For the purposes of this subsection (a), the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company. The Company agrees not to pay any dividend or make any distribution on shares of Common Stock held in its treasury. (b) In case the Company shall issue rights or warrants to all holders of any class of capital stock of the Company entitling them to subscribe for, purchase or acquire shares of Common Stock at a price per share less than the current market price per share (determined as provided in subsection (f) below) of the Common Stock on the date fixed for the determination of holders entitled to receive such rights or warrants, the Exchange Rate in effect at the opening of business on the day following the date fixed for such determination shall be adjusted by multiplying such Exchange Rate by a fraction the numerator of which shall be the sum of number of shares of Common Stock outstanding at the close of business on the date fixed for such determination plus the number of shares of Common Stock so offered for subscription, purchase or acquisition, and the denominator of which shall be the number of shares of Common Stock outstanding at the close of business on the date fixed for such determination plus the number of shares of Common Stock that could be purchased at the current market price with the aggregate offering price of the total number of shares of Common Stock so offered for subscription, purchase or acquisition. The adjusted Exchange Rate shall be effective immediately after the opening of business on the day following the date fixed for such determination. For the purposes of this subsection (b), the number of shares of Common Stock at any time outstanding shall not include shares held in the treasury of the Company. (c) In case the outstanding shares of Common Stock shall be multiplied or subdivided into a greater or smaller number of shares of Common Stock, the Exchange Rate in effect at the opening of business on the day following the day on which such subdivision becomes effective shall 7 9 be proportionately adjusted. The adjusted Exchange Rate shall be effective immediately after the opening of business on the day following the day on which such subdivision or combination becomes effective. (d) In case the Company shall, by dividend or otherwise, distribute to all holders of its Common Stock evidences of its indebtedness or assets (including securities but excluding: (i) any rights or warrants referred to in subsection (b) above; (ii) any dividend or distribution referred to in subsection (a) above; and (iii) any dividend or distribution paid in cash out of current or accumulated earnings), then in each case, the Exchange Rate in effect at the opening of business on the day following the date fixed for the determination of holders of Common Stock or other class of Common Stock entitled to receive such distribution shall be adjusted by multiplying such Exchange Rate by a fraction of which the numerator shall be such current market price per share (determined as provided in subsection (f) below) and the denominator shall be such current market price per share of the Common Stock on such date of determination (or, if earlier, on the date on which the Common Stock goes "ex-dividend" in respect of such distribution) less the then fair market value as determined by the Company Board (whose determination shall be conclusive) of the portion of the assets or evidences of indebtedness so distributed (and for which an adjustment to the Exchange Rate has not previously been made pursuant to the terms of this Section 3.01) applicable to one share of Common Stock on such date of determination. The adjusted Exchange Rate shall be effective immediately after the opening of business on the day following such date of determination. (e) The reclassification or change of Common Stock into securities including securities other than Common Stock (other than any reclassification on a consolidation or merger to which subsection (i) below applies) shall be deemed to involve: (i) a distribution of such securities other than Common Stock to all holders of Common Stock (and the effective date of such reclassification shall be deemed to be "the date fixed for the determination of holders of Common Stock entitled to receive such distribution" within the meaning of subsection (d) above); and, in the case of Common Stock (ii) a subdivision or combination, as the case may be, of the number of shares of Common Stock outstanding immediately prior to such reclassification into the number of shares of Common Stock outstanding immediately thereafter (and the effective date of such reclassification shall be deemed to be "the day on which such subdivision becomes effective" or "the day on which such combination becomes effective," as the case may be, and "the day on which such subdivision or combination becomes effective" within the meaning of subsection (c) above). (f) For the purpose of any computation under subsection (b) or (d) above, the current market price per share of Common Stock on any day shall be deemed to be the average of the Closing Prices of the Common Stock for the 20 consecutive Trading Days selected by the Company Board commencing no more than 30 Trading Days before and ending no later than the second Trading Day before the day in question; provided, that, in the case of subsection (d), if the period between the date of the public announcement of the dividend or distribution and the date for the determination of holders of Common Stock or other class of Common Stock entitled to receive such dividend or distribution (or, if earlier, the date on which the Common Stock goes "ex-dividend" in respect of such dividend or distribution) shall be less than 20 Trading Days, the period shall be such lesser number of Trading Days but, in any event, not less than five Trading Days. (g) No adjustment in the Exchange Rate pursuant to this Section 3.02 shall be required unless such adjustment would require an increase or decrease of at least 1% in such rate; provided, however, that any adjustments that by reason of this clause (g) are not required to be made shall be carried forward and taken into account in any subsequent adjustment and provided, further, that 8 10 adjustments shall be required and made in accordance with the provisions of this Section 3.01 (other than this clause (g)) not later than such time as may be required in order to preserve the tax free nature of a distribution to the holders of shares of Common Stock. Anything in this clause (g) to the contrary notwithstanding, the Company shall be entitled, at its option, to make such increases in the Exchange Rate, in addition to those required by this Section 3.01, as it in its discretion shall determine to be advisable in order that any stock dividend, subdivision or combination of shares, distribution of capital stock or rights or warrants to purchase stock or securities, or distribution of evidences of indebtedness or assets (other than cash dividends or distributions paid from current or accumulated earnings) or other event shall be a tax free distribution to holders for United States federal income tax purposes. All calculations under this clause (g) shall be made to the nearest cent. (h) Whenever the Exchange Rate is adjusted as provided in this Section 3.01, the Company shall provide written notice of such adjustment to ORBCOMM and the Holders, which notice shall include the Exchange Rate after such adjustment and shall set forth a brief statement of the facts requiring such adjustment and the manner of computing the same. (i) In case of any consolidation of the Company with, or merger of the Company into, any other entity, any merger of another entity into the Company (other than a merger that does not result in any reclassification, conversion, exchange or cancellation of outstanding shares of Common Stock) or any sale or transfer of all or substantially all of the assets of the Company, the Holders shall have the right thereafter to exchange Partnership Units only into the kind and amount of securities, cash and other property receivable on such consolidation, merger, sale or transfer by a holder of the number of shares of Common Stock into which such Partnership Units might have been exchanged immediately prior to such consolidation, merger, sale or transfer, assuming such holder of Common Stock is not the entity with which the Company consolidated or into which the Company merged or that merged into the Company or to which such sale or transfer was made, as the case may be (a "constituent person"), or an affiliate of a constituent person and such holder shall have failed to exercise its rights of election, if any, as to the kind or amount of securities, cash or other property receivable on such consolidation, merger, sale or transfer (provided, that if the kind or amount of securities, cash and other property receivable on such consolidation, merger, sale or transfer is not the same for each share of Common Stock held immediately prior to such consolidation, merger, sale or transfer by other than a constituent entity or an affiliate thereof and in respect of which such rights of election shall not have been exercised ("non-electing share"), then for the purpose of this subsection (i) the kind and amount of securities, cash and other property receivable on such consolidation, merger, sale or transfer by each non-electing share shall be deemed to be the kind and amount so receivable per share by a plurality of the non-electing shares. If necessary, appropriate adjustment shall be made in the application of the provisions set forth herein with respect to the rights and interests thereafter of the Holders, so that the provisions set forth herein shall thereafter be applicable, as nearly as may reasonably be practicable, to any shares of stock or other securities or property thereafter deliverable on the exchange of the Partnership Units. Any adjustment under this subsection (i) shall be evidenced by written notice of such adjustment in the manner set forth in subsection (h). The above provisions shall similarly apply to successive consolidations, mergers, sales or transfers. In case: (x) the Company shall take any action that would result in an adjustment to the Exchange Rate; (y) of any consolidation or merger to which the Company is a party and for which approval of any stockholders of the Company is required, or of the sale or transfer of all or substantially all of the assets of the Company; or (z) of the voluntary or involuntary dissolution, liquidation or winding-up of the Company; then the Company shall provide to ORBCOMM, at least 15 days prior to the applicable record or effective date hereinafter specified, a notice stating: (i) the date on which a 9 11 record is to be taken for the purpose of such actions, or, if the record is not to be taken, the date as of which the holders of Common Stock of record are to be determined; or (ii) the date on which such adjustment, consolidation, merger, sale, transfer, dissolution, liquidation or winding-up is expected to become effective, and the date as of which it is expected that holders of Common Stock of record shall be entitled to exchange their shares of Common Stock for securities, cash or other property deliverable on such consolidation, merger, sale, transfer, dissolution, liquidation or winding-up. Neither the failure to give such notice nor any defect therein shall affect the legality or validity of the proceedings described in clauses (x) through (z) above. SECTION 3.02. EXCHANGE RATE ADJUSTMENTS -- ORBCOMM ACTIONS. The Exchange Rate shall be adjusted from time to time as follows: (a) In case ORBCOMM shall pay or make a dividend or other distribution on any class of Partnership Units in Partnership Units, the Exchange Rate in effect at the opening of business on the day following the date fixed for the determination of the Holders entitled to receive such dividend or other distribution shall be adjusted by multiplying such Exchange Rate by a fraction the numerator of which shall be such number of Partnership Units outstanding at the close of business on the date fixed for such determination and the denominator of which shall be the sum of the number of Partnership Units outstanding at the close of business on the date fixed for such determination and the total number of Partnership Units constituting such dividend or other distribution. The adjusted Exchange Rate shall be effective immediately after the opening of business on the day following the date fixed for such determination. (b) In case ORBCOMM shall issue rights or warrants to all holders of any class of Partnership Units entitling them to subscribe for, purchase or acquire Partnership Units at a price per Partnership Unit less than the current market price per share (determined as provided in subsection (f) below) of Common Stock multiplied by the Exchange Rate on the date fixed for the determination of Holders entitled to receive such rights or warrants, the Exchange Rate in effect at the opening of business on the day following the date fixed for such determination shall be adjusted by multiplying such Exchange Rate by a fraction the numerator of which shall be the number of Partnership Units outstanding at the close of business on the date fixed for such determination plus the number of Partnership Units so offered for subscription, purchase or acquisition, and the denominator of which shall be the number of Partnership Units outstanding at the close of business on the date fixed for such determination plus the number of Partnership Units that the aggregate of the offering price of the total number of Partnership Units so offered for subscription, purchase or acquisition would purchase at a price per Partnership Units equal to the market price per share of Common Stock multiplied by the Exchange Rate in effect at the opening of business on the day following the date fixed for the determination of Holders entitled to receive such rights or warrants. The adjusted Exchange Rate shall be effective immediately after the opening of business on the day following the date fixed for such determination. (c) In case the outstanding Partnership Units shall be multiplied or subdivided into a greater or smaller number of Partnership Units, the Exchange Rate in effect at the opening of business on the day following the day on which such subdivision becomes effective shall be proportionately adjusted. The adjusted Exchange Rate shall be effective immediately after the opening of business on the day following the day on which such subdivision or combination becomes effective. (d) In case ORBCOMM shall, by dividend or otherwise, distribute to all Holders evidence of its indebtedness or assets (including securities but excluding: (i) any rights or warrants referred to in subsection (b) above; (ii) any dividend or distribution referred to in subsection: (a) 10 12 above; and (iii) any dividend or distribution paid in cash out of current or accumulated earnings), then in each case, the Exchange Rate in effect at the opening of business on the day following the date fixed for the determination of Holders entitled to receive such distribution shall be adjusted by multiplying such Exchange Rate by a fraction of which the numerator shall be the product of: (A) the current market price per share (determined as provided in subsection (f) below) of the Common Stock on such date of determination multiplied by the Exchange Rate (or, if earlier, on the date on which the Common Stock go "ex-dividend" in respect of such distribution); less (B) the then fair market value as determined by the ORBCOMM Committee (whose determination shall be conclusive and binding) of the portion of the assets or evidences of indebtedness so distributed (and for which an adjustment to the Exchange Rate has not previously been made pursuant to the terms of this Section 3.02) applicable to one Partnership Unit, and the denominator shall be such current market price per share of the Common Stock multiplied by the Exchange Rate, such adjustment to become effective immediately after the opening of business on the day following such date of determination. (e) The reclassification or change of Partnership Units into interests or securities including any interests in ORBCOMM other than Partnership Units shall be deemed to involve: (i) a distribution of such interests or securities other than Partnership Units to all Holders (and the effective date of such reclassification shall be deemed to be "the date fixed for the determination of Holders entitled to receive such distribution" within the meaning of subsection (d) above); and (ii) a subdivision or combination, as the case may be, of the number of shares of Partnership Units outstanding immediately prior to such reclassification into the number of Partnership Units outstanding immediately thereafter (and the effective date of such reclassification shall be deemed to be "the day on which such subdivision becomes effective" or "the day on which such subdivision becomes effective," as the case may be, and "the day on which such subdivision or combination become effective" within the meaning of subsection (c) above). (f) For the purpose of any computation under subsection (b) or (d) above, the current market price per share of Common Stock on any day shall be deemed to be the average of the Closing Prices of the Common Stock for the 20 consecutive Trading Days selected by the Company Board commencing no more than 30 Trading Days before and ending no later than the second Trading Day before the day in question. (g) No adjustment in the Exchange Rate pursuant to this Section 3.02 shall be required unless such adjustment would require an increase or decrease of at least 1% in such rate; provided, however, that any adjustments that by reason of this clause (g) are not required to be made shall be carried forward and taken into account in any subsequent adjustment and provided, further, that adjustments shall be required and made in accordance with the provisions of this Section 3.02 (other than this clause (g)) not later than such time as may be required in order to preserve the tax-free nature of a distribution to the Holders. Anything in this clause (g) to the contrary notwithstanding, ORBCOMM shall be entitled, at its option, to make such decreases in the Exchange Rate, in addition to those required by this Section 3.02, as it in its discretion shall determine to be advisable in order that any interest dividend, subdivision or combination of interests, distribution of interests or rights or warrants to purchase interests, or distribution of evidences of indebtedness or assets (other than cash dividends or distributions paid from current or accumulated earnings) or other event shall be a tax free distribution to holders of Partnership Units for United States federal income tax purposes. All calculations under this clause (g) shall be made to the nearest cent. (h) Whenever the Exchange Rate is adjusted as provided in this Section 3.02, ORBCOMM shall provide written notice of such adjustment to the Company and the Holders, 11 13 which notice shall include the Exchange Rate after such adjustment and shall set forth a brief statement of the facts requiring such adjustment and the manner of computing the same. SECTION 3.03. EXCHANGE RATE ADJUSTMENTS -- GENERAL. Anything in this Article III to the contrary notwithstanding, it is the intent of the parties that the Exchange Rate be adjusted to reflect events affecting the capital structure of ORBCOMM and the Company, including those events described in this Article III, as necessary or appropriate to place the parties to this Agreement in the same relative position that they would have been had such events not occurred, and the parties hereby agree that the Exchange Rate in effect at any time shall reflect such intent. ARTICLE IV. REGISTRATION RIGHTS At any time from and after the satisfaction of the milestones set forth in Section 2.03 hereof, the Company shall, after a written request (a "REGISTRATION REQUEST") from holders requesting registration under the Securities Act of an aggregate number of Registerable Securities representing not less than 5% of the Deemed Outstanding Shares, promptly notify all Holders in writing of the receipt of such request and each such Holder may elect (by written notice (a "REGISTRATION NOTICE") delivered to the Company within 10 Business Days after receipt by such Holder of the aforementioned notice from the Company, as the case may be), to join in the Registration Request and to have the Registerable Securities specified in its notice included in such registration pursuant to this Article IV. The Registration Notice to the Company must be in substantially the form of Exhibit D hereto and must be executed by the Holder.

Such six month period shall be extended by: (A) the period that any Suspension Notice is in effect under Section 5.01(c), (B) the period of any deferral under Section 5.03 during such period; and (C) if the registration covers Common Stock to be issued on exchange of Partnership Units which cannot be exchanged because of a deferral of exchanges pursuant to Section 2.10, by the period of any such deferral. The Company further agrees that if permitted by the rules and regulations of the Commission, the registration contemplated by this Article IV shall be a Shelf Registration. ARTICLE V.

(vi) use its reasonable best efforts to obtain the withdrawal of any order suspending the effectiveness of such registration statement or any post-effective amendment thereto at the earliest practicable date;

(viii) furnish to each Registering Holder and to each underwriter and selling agent, if any, at the expense of the Registering Holders, as many copies of the prospectus, including each preliminary prospectus, and any amendment or supplement thereto and such other documents as such Registering Holder or managing underwriter may reasonably request, in order to facilitate the public sale or other disposition of the Common Stock;

provided, that neither the Company nor ORBCOMM shall be required for any such purpose to: (w) qualify as a foreign corporation or foreign limited liability company in any jurisdiction wherein it would not otherwise be required to qualify but for the requirements of this paragraph 5.01(a)(ix); (x) file a general consent to service of process in any such jurisdiction; (y) subject itself to taxation in any jurisdiction where it is not already subject to taxation; or (z) make any changes to its Certificate of Incorporation, Bylaws or the Partnership Agreement, as the case may be, or any agreement between it and its stockholders or partners, as the case may be;

(xi) furnish to each Registering Holder, without charge, at least one conformed copy of such registration statement and any post-effective amendment thereto (without documents incorporated therein by reference or exhibits thereto, unless requested); (xii) cooperate with the Registering Holders and the managing underwriters, if any, to facilitate the timely preparation and delivery of certificates 14 16 representing the Common Stock to be sold, which shall not bear any restrictive legends; and, in the case of an underwritten offering, enable such Common Stock to be in such denominations and registered in such names as the managing underwriters may request at least two Business Days prior to any sale of the Common Stock; and (xiii) enter into and deliver all such customary agreements (including underwriting or purchase agreements), documents and take such other actions (including causing the delivery of opinions of counsel and "comfort" letters of independent certified public accountants) as are reasonably requested of the Company or ORBCOMM to expedite or facilitate the disposition of the Common Stock. (b) ORBCOMM hereby agrees to provide the Company with all assistance reasonably necessary for the Company to comply with its obligations under Section 5.01(a). (c) Each Registering Holder, by execution and delivery of a Registration Notice, shall be deemed to have agreed that, on receipt of any: (i) notice from the Company of the happening of any event of the kind described in Section 5.01(a)(iv)(B), (C) or (D); (ii) notice from the Company that it is in possession of material information that has not been disclosed to the public and the Company reasonably deems it to be advisable not to disclose such information in a registration statement or prospectus; or (iii) notice from the Company that it is in the process of a registered offering of securities and the Company reasonably deems it to be advisable to have Registering Holders temporarily discontinue disposition of Common Stock pursuant to the registration statement (in each case, such notice being hereinafter referred to as a "SUSPENSION NOTICE"), such Registering Holder will forthwith discontinue disposition of Common Stock pursuant to any registration statement and shall not be entitled to the benefits provided under Article VIII hereof with respect to any sales made by it in contravention of this subsection, until such Registering Holder's receipt of the copies of the supplemented or amended prospectus contemplated by Section 5.01(a)(v) or a notice in accordance with Section 5.01(a)(vi) hereof that any order suspending the effectiveness of the registration statement has been withdrawn, or, in the case of (ii) or (iii) above, until further notice from the Company that disposition of Registerable Securities may resume. Any Suspension Notice must be based on a good faith determination of the Company Board that such Suspension Notice is necessary. In the case of a Suspension Notice, if so directed by the Company, each Registering Holder by execution and delivery of a Registration Notice, shall be deemed to have agreed to deliver to the Company all copies in its possession, other than permanent file copies then in such Registering Holder's possession, of the prospectus covering such Common Stock that is current at the time of receipt of such notice. If the Company shall issue a Suspension Notice to suspend the disposition of Common Stock pursuant to any registration statement, the Company shall extend the period during which such registration statement shall be maintained effective pursuant to this Agreement by the number of days during the period from and including the date of the giving of a Suspension Notice to and including the date when the Registering Holders shall have received copies of the supplemented or amended prospectus necessary to resume such dispositions or received notice that any order suspending dispositions of the Common Stock has been withdrawn. (d) By execution and delivery of a Registration Notice, each Registering Holder shall be deemed to have agreed that the Company may require such Registering Holder to: (i) furnish in writing to the Company such information regarding such Registering Holder and such Registering Holder's intended method of distribution of its Common Stock as the Company may from time to time reasonably request in writing, but only to the extent that such information is required in order to comply with the Securities Act; and (ii) enter into and deliver all such customary agreements (including underwriting or purchase agreements) and documents (including legal opinions) as are 15 17 reasonably requested of such Registering Holder to expedite or facilitate the disposition of its Common Stock. Each such Registering Holder, by execution and delivery of a Registration Notice, shall be deemed to have agreed to notify the Company as promptly as practicable of any inaccuracy or change in information previously furnished by such Registering Holder to the Company or of the occurrence of any event in either case as a result of which any prospectus relating to such registration contains or would contain an untrue statement of a material fact regarding such Registering Holder or such Registering Holder's intended method of distribution of its Common Stock or omits to state any material fact regarding such Registering Holder or such Registering Holder's intended method of distribution of its Common Stock required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances then existing, and promptly to furnish to the Company any additional information required to correct and update any previously furnished information or required so that such prospectus shall not contain, with respect to such Registering Holder or the distribution of its Common Stock, an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in light of the circumstances then existing. Each such Registering Holder, by execution and delivery of a Registration Notice, shall be deemed to have agreed to comply with the provisions of the Securities Act and the Exchange Act applicable to such Registering Holder with respect to the disposition by such Registering Holder of Common Stock covered by such registration statement in accordance with the intended methods of disposition by such Registering Holder set forth in such registration statement. SECTION 5.02. REGISTRATION OF ADDITIONAL SHARES. The registration statement filed pursuant to this Article V, may, in addition to the shares of Common Stock subject to registration rights set forth in Article IV above, include other securities for sale for the Company's own account or for the account of any other person. SECTION 5.03. REGISTRATION DEFERRAL PERIOD. Notwithstanding the foregoing, if the Company shall furnish to the Registering Holders a certificate (the "COMPANY CERTIFICATE") signed by the Chief Executive Officer of the Company stating that, in the good faith judgment of the Company Board, acting reasonably and in the best interest of the Company, it would be detrimental to the Company and its stockholders for such registration statement to be filed or for the Registering Holders to sell Common Stock exchanged pursuant to this Agreement under any such effective registration statement and it is therefore necessary to defer the filing of the registration statement or suspend the ability of the Registering Holders to sell Common Stock exchanged pursuant to this Agreement under an effective registration statement, each Registering Holder, by execution and delivery of a Registration Notice, hereby agrees that the filing of the registration statement shall be deferred, or the ability of such Registering Holder to sell Common Stock acquired pursuant to this Agreement under an effective registration statement shall be suspended, for a period of not more than an aggregate of 90 days from the date of the Company Certificate; provided however, that the Company may not utilize this right more than one time in any twelve-month period and the 90-day period shall be reduced by any period of time in the prior six months covered by a Suspension Notice as to such Registering Holders under Section 5.01(c). On any delivery of a Company Certificate pursuant to this Section 5.03, each Registering Holder, by execution and delivery of a Registration Notice, shall be deemed to have agreed that it shall not dispose of its Common Stock covered by the registration statement during the above-stated 90-day period other than pursuant to the limitations applicable to "restricted securities" within the meaning of Rule 144 under the Securities Act ("RULE 144") and that any sale by such Registering Holder or its designee of such Common Stock during this period shall be made only to a person who has agreed to comply with the provisions of this Section 5.03 for the balance of the 90-day period. SECTION 5.04. EXPENSES. By execution and delivery of a Registration Notice, each Registering Holder shall be deemed to have agreed that: (a) all registration expenses incurred in 16 18 connection with any registration, qualification or compliance pursuant to this Article V, including without limitation, all registration and filing fees, printing expenses, fees and disbursements of counsel for the Company and of the Company's accountants, blue sky fees and expenses and the expenses of any special audits incident to or required by any such registration, shall be borne by such Registering Holder pro rata on the basis of the number of shares of Common Stock of such Registering Holder included in such registration; and (b) such Registering Holder shall pay its own selling expenses. Selling expenses shall mean all costs and commissions applicable to the sale of the Common Stock and all fees and disbursements of counsel and other professionals. To the extent that the Company registers for primary offering additional securities pursuant to Section 5.02, the Company shall bear its pro rata share of the above referenced registration expenses and its own selling expenses. SECTION 5.05. LISTING. The Company shall use its reasonable best efforts to list all Common Stock covered by a registration statement filed pursuant to this Article V on each securities exchange or automated quotation system on which any of the Common Stock is then listed unless the Company and ORBCOMM agree not to have the Company do so. ARTICLE VI. RULE 144 INFORMATION With a view to making available to the Holders the benefits of Rule 144 and any other rule or regulation of the Commission that may at any time permit a Holder to sell restricted securities or securities subject to Rule 145 under the Securities Act, of the Company to the public without registration, the Company agrees to: (a) make and keep public information available, as required by Rule 144; (b) use its reasonable best efforts to file with the Commission in a timely manner all reports and other documents required of the Company under the Securities Act and the Exchange Act; and (c) furnish to any Holder forthwith on request: (i) a written statement by the Company that it has complied with the reporting requirements of Rule 144, the Securities Act and the Exchange Act; (ii) a copy of the most recent annual or quarterly report of the Company and such other reports and documents so filed by the Company; and (iii) such other information as may be reasonably requested in availing any Holder of any rule or regulation of the Commission that permits the selling of any Common Stock without registration. ARTICLE VII. EQUAL TREATMENT Nothing contained in this Agreement shall prohibit the Company, following the first exchange of Partnership Units for Common Stock pursuant to this Agreement, from offering to purchase Partnership Units held by a Holder for cash or any other consideration, or to exchange additional shares of its Common Stock for Partnership Units held by a Holder, all on such terms and conditions as the Company and such Holder may agree, provided that the Company shall offer to purchase or exchange on such terms and conditions equally pro rata to all the other Holders. Except as set forth in Article II hereof, the Company shall not permit any other exchanges or purchases with any Holder. ARTICLE VIII. INDEMNIFICATION SECTION 8.01. INDEMNIFICATION BY ORBCOMM. ORBCOMM will indemnify and hold harmless each Indemnified Person against any losses, claims, damages or liabilities, joint or several, to which such Indemnified Person may become subject, under the Securities Act or otherwise, that directly or indirectly arise out of or are based on an untrue statement or alleged untrue statement of a material fact contained in any preliminary prospectus, the registration statement or the prospectus, or any amendment or supplement thereto, or arise out of or are based on the omission or alleged omission to 17 19 state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, prepared pursuant to the transactions contemplated by this Agreement, and will reimburse such Indemnified Person for any legal or other expenses reasonably incurred by such Indemnified Person in connection with investigating or defending any such action or claim as such expenses are incurred; provided, however, that ORBCOMM shall not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based on: (a) in the case of indemnification of the Company or its officers and directors, an intentional act or omission of the Company or any such officers, directors or any employee of the Company that was contrary to any written instruction or request of ORBCOMM or that amounted to willful misconduct on the part of such officer, director, employee or agent of the Company who is not also an employee of ORBCOMM; and (b) in the case of a party other than the Company or its officers and directors, an untrue statement or alleged untrue statement or omission or alleged omission made in any preliminary prospectus, the registration statement or the prospectus or any such amendment or supplement in reliance on and in conformity with written information furnished to the Company by such Indemnified Person expressly for use therein. SECTION 8.02. INDEMNIFICATION BY REGISTERING HOLDERS. Each Registering Holder, by execution and delivery of a Registration Notice, shall: (a) be deemed to have agreed that it will indemnify and hold harmless each Indemnified Person against any losses, claims, damages or liabilities to which such Indemnified Person may become subject, under the Securities Act or otherwise, that directly or indirectly arise out of or are based on an untrue statement or alleged untrue statement of a material fact contained in any preliminary prospectus, the registration statement or the prospectus, or any amendment or supplement thereto, or arise out of or are based on 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 such untrue statement or alleged untrue statement or omission or alleged omission was made in any preliminary prospectus, the registration statement or the prospectus or any such amendment or supplement in reliance on and in conformity with written information furnished to the Company by such Registering Holder expressly for use therein; and (b) reimburse each Indemnified Person for any legal or other expenses reasonably incurred by such Indemnified Person in connection with investigating or defending any such action or claim as such expenses are incurred. SECTION 8.03. PROCEEDINGS. Promptly after receipt by an Indemnified Person of notice of the commencement of any action, suit or proceeding as to which a claim in respect thereof is to be made under this Article VIII, the Indemnified Person shall notify the party against whom the Indemnified Person intends to assert a claim for indemnification (an "INDEMNIFYING PERSON") in writing of the commencement thereof, but the omission so to notify the Indemnifying Person shall not relieve the Indemnifying Person from any liability that it may have to any Indemnified Person otherwise than under this Article, unless the Indemnifying Person is materially prejudiced thereby. In case any such action shall be brought against any Indemnified Person and it shall notify the Indemnifying Person of the commencement thereof, the Indemnifying Person shall be entitled to participate therein and, to the extent that it shall wish, to assume the defense thereof, with counsel reasonably satisfactory to such Indemnified Person, and, after notice from the Indemnifying Person to such Indemnified Person of its election so to assume the defense thereof, the Indemnifying Person shall not be liable to such Indemnified Person under such section for any legal expenses of other counsel or any other expenses, in each case subsequently incurred by such Indemnified Person, in connection with the defense thereof other than reasonable costs of investigation. The Indemnifying Person shall not, without the written consent of the Indemnified Person, effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution may be sought hereunder (whether or not the Indemnified Person is an actual or potential party to such action or claim) unless such settlement, compromise or judgment: (a) includes an unconditional release 18 20 of such Indemnified Person from all liability arising out of such action or claim; and (b) does not include a statement as to or an admission of fault, culpability or a failure to act, by or on behalf of such Indemnified Person. No Indemnified Person shall effect the settlement or compromise of, or consent to the entry of any judgment with respect to, any pending or threatened action or claim in respect of which indemnification or contribution has been or may be sought hereunder without the prior written consent of the Indemnifying Person. By execution and delivery of a Registration Notice, each Registering Holder shall be deemed to have agreed to the provisions of this Section 8.03. SECTION 8.04. CONTRIBUTION. In order to provide for just and equitable contribution in circumstances in which the indemnity agreement provided for in this Article VIII is for any reason held to be unenforceable by an Indemnified Person although applicable in accordance with its terms, the Indemnified Person on the one hand and the Indemnifying Person on the other hand shall contribute to the aggregate losses, liabilities, claims, damages and expenses of the nature contemplated by such indemnity agreement incurred by the Indemnified Person; provided, however, that no Person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. As between the Indemnifying Person and each Indemnified Person, such parties shall contribute to the aggregate losses, liabilities, claims, damages and expenses of the nature contemplated by such indemnity agreement in such proportion as shall be appropriate to reflect: (a) the relative benefits received by the Indemnifying Person on the one hand and the Indemnified Person on the other hand, from the offering of the Common Stock included in such offering; and (b) the relative fault of the Indemnifying Person on the one hand and the Indemnified Person on the other hand, with respect to the statements or omissions that resulted in such loss, liability, claim, damage or expense, or action in respect thereof, as well as any other relevant equitable considerations. It is agreed that it would not be just and equitable if contribution pursuant to this Article VIII were to be determined by pro rata allocation or by any other method of allocation that does not take into account the relevant equitable considerations set forth herein. For purposes of this Article VIII, each Person, if any, who controls a party covered by the indemnity provisions of this Article VIII within the meaning of Section 15 of the Securities Act shall have the same rights to contribution as such party. By execution and delivery of a Registration Notice, each Registering Holder shall be deemed to have agreed to the foregoing contribution provisions. ARTICLE IX.

XII. MISCELLANEOUS SECTION 12.01. SUCCESSORS AND ASSIGNS.
