In determining whether the Holders of the required principal amount of Notes have concurred in any direction, waiver, consent or notice, Notes owned by the Issuers, the Guarantors or any of their respective Affiliates shall be considered as though they are not outstanding, except that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, waiver or consent, only Notes which the Trustee actually knows are so owned shall be so considered. The Issuers and the Guarantors shall notify the Trustee, in writing, when any of the Issuers, the Guarantors or any of their Affiliates repurchases or otherwise acquires Notes and the aggregate principal amount of such Notes so repurchased or otherwise acquired. 23 28 SECTION 2.10. TEMPORARY NOTES. Pending the preparation of definitive Notes, the Issuers may execute, and upon written order in the form of an Officers' Certificate the Trustee shall authenticate and deliver, temporary Notes which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Notes in lieu of which they are issued and with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Notes may determine, as evidenced by their execution of such Notes. If temporary Notes are issued, the Issuers shall cause definitive Notes to be prepared without unreasonable delay. After the preparation of definitive Notes, the temporary Notes shall be exchangeable for definitive Notes upon surrender of the temporary Notes at any office or agency of the Issuers designated pursuant to Section 4.2, without charge to the Holder. Upon surrender for cancellation of any one or more temporary Notes, the Issuers shall execute and the Trustee shall authenticate and deliver in exchange therefor a like tenor and principal amount of definitive Notes of authorized denominations. Until so exchanged, the temporary Notes shall in all respects be entitled to the same rights, benefits and privileges under this Indenture as definitive Notes. SECTION 2.11. CANCELLATION. The Issuers may at any time deliver to the Trustee for cancellation any Notes previously authenticated and delivered hereunder which the Issuers may have acquired in any manner whatsoever. The Registrar and Paying Agent shall forward to the Trustee any Notes surrendered to them for registration of transfer, exchange or payment. The Trustee shall cancel all Notes surrendered for registration of transfer, exchange, replacement or cancellation and shall destroy cancelled Notes (subject to the record retention requirements of the Exchange Act) unless the Company directs the Trustee in writing that such cancelled Notes shall be returned to them. No Notes shall be authenticated in lieu of or in exchange for any Notes cancelled as provided in this Section, except as expressly permitted by this Indenture. SECTION 2.12. PAYMENT OF INTEREST; DEFAULTED INTEREST. Interest on any Note which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name that Note is registered in the Note Register at the close of business on the applicable Record Date. With respect to any payment of Revenue Participation Interest, the Issuers shall deliver to the Trustee, not less than five (5) Business Days prior to the date on which such Revenue Participation Interest is payable, and promptly following a written request therefor made by the Trustee, at any other time, an Officers' Certificate certifying the amount and the calculations with respect thereto. The Trustee shall be entitled to rely conclusively on the information set forth in any such Officers' Certificate and shall have no duty or obligation to recalculate or otherwise verify the amounts or calculations set forth therein. Subject to the foregoing provisions of this Section, each Note delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Note shall carry the rights to interest (including Revenue Participation Interest, if any) accrued and unpaid, and to accrue, which were carried by such other Note. If the Issuers default in a payment of interest (including Revenue Participation Interest, if any) on the Notes, they shall pay the Persons who are Holders on a subsequent special record date, which date shall be the fifteenth day next preceding the date fixed by the Issuers for the payment of defaulted interest, or the next succeeding Business Day if such date is not a Business Day. At least 15 days before the subsequent special record date, the Issuers shall mail to each Holder, as of a recent date selected by the Issuers, with a copy to the Trustee, a notice that states the subsequent special record date, the payment date and the amount of defaulted interest, and interest payable on such defaulted interest, if any, to be paid. SECTION 2.13. CUSIP NUMBER. The Issuers in issuing the Notes shall use a CUSIP number, and the Trustee shall use the CUSIP number in notices of redemption or exchange as a convenience to Holders; provided, however, that no representation is hereby deemed to be made by the Trustee as to the correctness or accuracy of the CUSIP number printed in the notice or on 24 29 the certificates representing the Notes, and that reliance may be placed only on the other identification numbers printed on the certificates representing the Notes. SECTION 2.14. DEPOSIT OF MONEYS. On each Interest Payment Date and each date on which principal of the Notes is payable, the Issuers shall, not later than 11:00 a.m., New York City time, deposit with the Paying Agent in immediately available funds money sufficient to make any cash payments due on such date in a timely manner which permits the Paying Agent to remit payment to the Holders on such date. SECTION 2.15. BOOK-ENTRY PROVISIONS FOR GLOBAL NOTE.

In addition, certificated Notes shall be transferred to all beneficial owners in exchange for their beneficial interests in the Global Note if (i) the Depository notifies the Issuers that it is unwilling or unable to continue as Depository for the Global Note and a successor depositary is not appointed by the Issuers within 90 days of such notice or (ii) an Event of Default has occurred and is continuing and the Registrar has received a request from the Depository to issue certificated Notes. (c) In connection with any transfer or exchange of a portion of the beneficial interest in the Global Note to beneficial owners pursuant to paragraph (b), the Registrar shall (if one or more certificated Notes are to be issued) reflect on its books and records the date and a decrease in the principal amount of the Global Note in an amount equal to the principal amount of the beneficial interest in the Global Note to be transferred, and the Company shall execute, and the Trustee shall authenticate and deliver, one or more certificated Notes of like tenor and amount. (d) In connection with the transfer of the entire Global Note to beneficial owners pursuant to paragraph (b), the Global Note shall be deemed to be surrendered to the Trustee for cancellation, and the Company shall execute, and the Trustee shall authenticate and deliver, to each beneficial owner identified by the Depository in exchange for its beneficial interest in the Global Note, an equal aggregate principal amount of certificated Notes of authorized denominations.

If less than all the Notes are to be redeemed in any redemption, the Notes to be redeemed shall be selected by the Trustee by prorating, as nearly as may be practicable, the principal amount of Notes to be redeemed or in such other manner as the Trustee shall deem fair and appropriate. In any proration pursuant to this Section, the Trustee shall make such adjustments, reallocations and eliminations as it shall deem proper (and in compliance with the requirements of the principal national securities exchange, if any, on which the Notes are listed) to the end that the principal amount of Notes so prorated shall be $1,000 or a multiple thereof, by increasing or decreasing or eliminating the amount which would be allocable to any Holder on the basis of exact proportion by an amount not exceeding $1,000.

The Trustee shall promptly notify the Issuers and each Registrar (if other than the Trustee) in writing of the Notes selected for redemption and, in the case of any Notes selected for partial redemption, the principal amount thereof to be redeemed.

Upon surrender of any such Note for redemption in accordance with said notice, such Note shall be paid by the Issuers at the Redemption Price, together with accrued and unpaid interest (including Revenue Participation Interest, if any) and Liquidated Damages (if any) to the Redemption Date. If any Note called for redemption shall not be so paid upon surrender thereof for redemption, the principal and premium (if any) shall, until paid, bear interest (including Revenue Participation Interest) from the Redemption Date at the rate provided by the Note. SECTION 3.9. NOTES REDEEMED IN PART. Any Note that is to be redeemed only in part shall be surrendered at an office or agency of the Issuers designated for that purpose pursuant to Section 4.2 (with, if the Issuers or the Trustee so require, due endorsement by, or a written instrument of transfer in form satisfactory to the Issuers and the Trustee duly executed by, the Holder thereof or its attorney duly authorized in writing), and the Issuers shall execute, and the Trustee shall authenticate and deliver to the Holder of such Note without service charge, a new Note or Notes of like tenor, of any authorized denomination as requested by such Holder, in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Note so surrendered.

The Trustee or the Paying Agent, as the case may be, shall return to the Issuers no later than five days following the date of payment, any money that exceeds such installment of principal and premium (if any) of, and interest (including Revenue Participation Interest, if any) and Liquidated Damages (if any) payable on, the Notes. The Issuers shall pay, to the extent such payments are lawful, interest on overdue principal and on overdue installments of interest (including Revenue Participation Interest, if any) (without regard to any applicable grace periods) from time to time on demand at the rate borne by the Notes plus 1% per annum. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months. Notwithstanding anything to the contrary contained in this Indenture, the Issuers may, to the extent they are required to do so by law, deduct or withhold income or other similar taxes imposed by the United States of America from principal or interest payments hereunder. SECTION 4.2. MAINTENANCE OF OFFICE OR AGENCY. The Issuers shall maintain the office or agency required under Section 2.3. The Issuers shall give prior written notice to the Trustee of the location, and any change in the location, of such office or agency. If at any time the Issuers shall fail to maintain any such required office or agency or shall fail to furnish the Trustee with the address thereof, such presentations, surrenders, notices and demands may be made or served at the address of the Trustee set forth in Section 11.2. The Issuers may also from time to time designate one or more other offices or agencies where the Notes may be presented or surrendered for any or all such purposes and may from time to time rescind such designations; provided, however, that no such designation or rescission shall in any manner relieve the Issuers of their obligation to maintain an office or agency in the Borough of Manhattan, The City of New York for such purposes. The Issuers shall give prior written notice to the Trustee of any such designation or rescission and of any change in the location of any such other office or agency. The Issuers hereby designate the Corporate Trust Office of the Trustee as such office or agency of the Issuers in accordance with Section 2.3. SECTION 4.3. CORPORATE OR PARTNERSHIP EXISTENCE. Except as otherwise permitted by Articles IV and V, each Credit Party shall do or cause to be done, at its own cost and expense, all things necessary to preserve and keep in full force and effect its corporate or partnership existence and the corporate or partnership existence of each of its Subsidiaries in accordance with the respective organizational documents of each such Credit Party and each such Subsidiary and the material rights (charter and statutory) and franchises of such Credit Party and each such Subsidiary; provided, however, that no Credit Party shall be required to preserve, with respect to itself, any material right or franchise and, with respect to any of its Subsidiaries, any such existence, material right or franchise, if the Board of Directors or other applicable governing body of such Credit Party shall determine in good faith that the preservation thereof is no longer desirable in the conduct of the business of such Credit Party and its Subsidiaries, taken as a whole. SECTION 4.4. PAYMENT OF TAXES AND OTHER CLAIMS. Each Credit Party shall pay or discharge or cause to be paid or discharged, before the same shall become delinquent, (i) all material taxes, assessments and governmental charges (including withholding taxes and any penalties, interest and additions to taxes) levied or imposed upon it or any of its Subsidiaries or its properties or any of its Subsidiaries' properties and (ii) all material lawful claims for labor, materials and supplies that, if unpaid, would by law become a Lien upon its properties or any of its Subsidiaries' properties; provided, however, that no Credit Party shall be required to pay or discharge or cause to be paid or discharged any such tax, assessment, charge or claim whose amount, applicability or validity is being contested in good faith and by appropriate proceedings 30 35 properly instituted and diligently conducted and for which adequate reserves, to the extent required under GAAP, have been taken or where the failure to effect such payment is not adverse in any material respect to the Holders. SECTION 4.5. MAINTENANCE OF PROPERTIES AND INSURANCE. (a) Each Credit Party shall, and shall cause each of its Subsidiaries to, maintain its properties in good working order and condition (subject to ordinary wear and tear) and make all reasonably necessary repairs, renewals, replacements, additions and improvements required for it to actively conduct and carry on its business; provided, however, that nothing in this Section 4.5 shall prevent any Credit Party or any of its Subsidiaries from discontinuing the operation and maintenance of any of its properties if such discontinuance is, in the good faith judgment of the Board of Directors or other governing body of the Credit Party or the Subsidiary concerned, as the case may be, desirable in the conduct of its businesses and is not disadvantageous in any material respect to the Holders. (b) Each Credit Party shall maintain insurance (including appropriate self-insurance) against loss or damage of the kinds that, in the good faith judgment of such Credit Party, are adequate and appropriate for the conduct of the business of such Credit Party and its Subsidiaries in a prudent manner, with reputable insurers or with the government of the United States of America or an agency or instrumentality thereof, in such amounts, with such deductibles, and by such methods as shall be customary, in the good faith judgment of such Credit Party, for companies similarly situated in the industry (provided that insurance with respect to the satellites shall be governed by clause (c) below). (c) In addition to the foregoing, the Issuers shall maintain in full force and effect: (i) on or prior to the date on which at least 26 satellites have been launched and tested and, together with the related ground systems, are reasonably believed by the Company to be ready for commercial operation as part of the ORBCOMM System, at the time of the launch of each such satellite, launch insurance in an amount sufficient to provide for the procurement of a launch vehicle in the event of a launch failure; (ii) at all times following the date a satellite has been successfully launched and deployed and is placed in commercial service, in-orbit insurance with respect to such satellite representing the value of such failed satellite (taking into account the foregone useful life of such satellite) and the pro rata cost of a launch vehicle, payable in the event that such satellite ceases to be used for commercial revenue producing service (provided that such insurance may contain customary provisions for deductible payments and minimum thresholds for satellite failure); and (iii) in the event (1) the Company is required to use four or more of the Company's "ground spare" satellites available under the Procurement Agreement, or (2) the Company loses four or more satellites within any plane of eight satellites, or six or more satellites within any two planes of eight satellites, as a result of a launch failure or in-orbit failure prior to the placement of satellites into commercial service, for the time periods specified in clause (i) above, insurance sufficient to provide for the construction and launch of replacement satellites of equivalent capacity and functionality payable in the event of a loss of four or more satellites within any plane of eight satellites, or six or more satellites within any two planes of eight satellites, as a result of a launch failure or in-orbit failure prior to placement of such satellites into commercial service. Notwithstanding the foregoing, the Company shall not be obligated to obtain launch or in-orbit insurance with respect to the two satellites operational on the Issue Date and the two satellites with respect to which the Company has the option to launch on a Taurus launch vehicle or launch insurance with respect to other launches of up to an aggregate of three additional satellites on a secondary basis. The obligation of the Issuers to maintain insurance pursuant to clause (c) above may be satisfied by any combination of: (i) insurance commitments obtained from any recognized insurance provider; (ii) insurance commitments obtained from any entity other than an entity referred to in clause (i) if the general partners of the Company determine in good faith (evidenced by a unanimous resolution of the general partners of the Company and set forth in an Officers' Certificate delivered to the Trustee) that such entity is credit-worthy and otherwise capable of bearing the financial risk of providing such insurance and making payments in respect of any claims on a timely basis; and (iii) unrestricted cash segregated and maintained by the Company in a segregated account established with an Eligible Institution (the "Insurance Account") solely for disbursement in accordance with the terms of clause (c) above ("Cash Insurance"), and to be held in trust for the sole and express benefit of the Holders. 31 36 Within 30 days following any date on which the Issuers are required to obtain insurance pursuant hereto, the Company will deliver to the Trustee an insurance certificate certifying the amount of insurance then carried, and in full force and effect, and an Officers' Certificate stating that such insurance, together with any other insurance or Cash Insurance maintained by the Issuers, complies with the provisions hereof. In addition, the Issuers will cause to be delivered to the Trustee within 30 days following January 1 of each year, commencing January 1, 1997, an insurance certificate setting forth the amount of insurance then carried, which insurance certificate shall entitle the Trustee to: (i) notice of any claim under any such insurance policy; and (ii) at least 30 days' notice from the provider of such insurance prior to the cancellation of any such insurance. In the event that the Issuers maintain any Cash Insurance in satisfaction of any part of their obligation to maintain insurance pursuant to this covenant, the Issuers shall deliver, in lieu of any insurance certificate otherwise required by this covenant, an Officers' Certificate to the Trustee certifying the amount of such Cash Insurance. In the event that the Issuers receive any proceeds of any insurance that they are required to maintain pursuant to this covenant, the Issuers shall promptly deposit such proceeds into an escrow account established with an Eligible Institution for such purpose. If the Issuers maintain any Cash Insurance in satisfaction of any part of their obligation to maintain insurance pursuant to this covenant, the Issuers shall transfer the cash maintained in the Insurance Account to such escrow account upon the occurrence of the event (e.g., a launch failure) that would have entitled the Issuers to the payment of insurance had the Issuers purchased insurance from a recognized insurance provider. The Company may use monies on deposit in such escrow account for the design, development, construction, procurement, launch and insurance of replacement satellites if: (i) the Company delivers to the Trustee a certificate of the Company's President certifying that such replacement satellites are of comparable or superior technological capability as compared with the satellites being replaced; and (ii) within 30 days following the receipt of such insurance proceeds, the Company delivers to the Trustee an Officers' Certificate certifying that (A) such replacement satellites are scheduled to be launched within 18 months following delivery from the escrow account of such insurance proceeds; and (B) the Company will have sufficient funds to service the Company's projected debt service requirements until the scheduled launch of such replacement satellite and to develop, construct, launch and insure such replacement satellite. In the event (an "Insurance Contingency Event") that (i) four or more satellites within any plane of eight satellites, or six or more satellites within any two planes of satellites, suffer an in-orbit failure prior to such satellites being placed in commercial service, and, as a result thereof, the Company is required to launch its ground spare satellites; and (ii) there are not sufficient insurance proceeds to procure a launch vehicle for the launch of such ground spare satellites (the amount of any such insufficiency being referred to as the "Insurance Launch Deficiency Amount"), then the Company shall be required to draw-down on the Partners' Insurance Contingent Commitment (as defined below) prior to any further borrowings under any Bank Credit Facility if, but only to the extent that, the Company's existing levels of cash and cash equivalents are less than $15 million at any time after the Insurance Contingency Event through the date the Company has 26 satellites in commercial operation (the "Full Deployment Date"). As used herein, "Partners' Insurance Contingent Commitment" shall mean a commitment by Teleglobe and Orbital, each dated August 7, 1996, to provide, in the aggregate, up to the lesser of (x) $15 million less any amounts drawn under the Partners' Insurance Contingent Commitment or (y) the Insurance Launch Deficiency Amount in capital contributions or debt financing expressly subordinated to the Notes (at then prevailing interest rates, which subordinated debt financing shall not mature or be subject to acceleration prior to maturity of the Notes and which shall not provide for cash interest payments prior to maturity of the Notes) from and after an Insurance Contingency Event through the Full Deployment Date. The Company shall maintain the Partners' Insurance Contingent Commitment in full force and effect from the Issue Date through the Full Deployment Date (and the Partners' Insurance Contingent Commitments shall thereafter expire) and the Company shall enforce all obligations under such Partners' Insurance Contingent Commitment in accordance with their terms.

Pending the final application of any such Net Proceeds, the Issuers may temporarily invest such Net Proceeds in any manner that is not prohibited by this Indenture. Any Net Proceeds that are not applied or invested as provided in the first sentence of this paragraph will be deemed to constitute "Excess Proceeds." When the aggregate cumulative amount of Excess Proceeds exceeds $5 million (the "Asset Sale Offer Trigger Date"), the Issuers shall be required to make an offer to all Holders of Notes (an "Asset Sale Offer") to purchase on a date not less than 30 nor more than 45 days following the Asset Sale Offer Trigger Date the maximum principal amount of Notes that may be purchased out of the Excess Proceeds (and not solely the amount in excess of $5 million), at an offer price in cash in an amount equal to 100% of the principal amount thereof, plus accrued and unpaid interest (including Revenue Participation Interest, if any) and Liquidated Damages (if any) thereon to the date of purchase, in accordance with the procedures set forth in clause (b). To the extent that the offer price of the aggregate amount of Notes tendered pursuant to an Asset Sale Offer is less than the Excess Proceeds, the Issuers may use any remaining Excess Proceeds for general business purposes. If the offer price of the aggregate amount of Notes surrendered by Holders thereof exceeds the amount of Excess Proceeds, the Trustee will select the Notes to be purchased on a pro rata basis. 40 45 Upon completion of such offer to purchase, the amount of Excess Proceeds will be reset at zero. The Asset Sale Offer shall remain open for a period of 20 Business Days or such longer period as may be required by law. (b) Each notice of an Asset Sale Offer pursuant to this Section 4.15 shall be mailed or caused to be mailed, by first class mail, by the Company not more than 25 days after the Asset Sale Offer Trigger Date to all Holders at their last registered addresses as of a date within 15 days of the mailing of such notice, with a copy to the Trustee. The notice shall contain all instructions and materials necessary to enable such Holders to tender Notes pursuant to the Asset Sale Offer and shall state the following terms: (1) that the Asset Sale Offer is being made pursuant to Section 4.15 and that all Notes tendered will be accepted for payment; provided, however, that if the aggregate principal amount of Notes tendered in an Asset Sale Offer plus accrued interest (including Revenue Participation Interest, if any) and Liquidated Damages (if any) at the expiration of such offer exceeds the aggregate amount of the Asset Sale Offer, the Trustee shall select the Notes to be purchased on a pro rata basis (with such adjustments as may be deemed appropriate by the Trustee so that only Notes in denominations of $1,000 or multiples thereof shall be purchased); (2) the purchase price (including the amount of accrued interest (including the method by which Revenue Participation Interest, if any, will be calculated)) and the purchase date (which shall be 20 Business Days from the date of mailing of notice of such Asset Sale Offer, or such longer period as required by law) (the "Proceeds Purchase Date"); (3) that any Note not tendered will continue to accrue interest (including Revenue Participation Interest); (4) that, unless the Issuers default in making payment therefor, any Note accepted for payment pursuant to the Asset Sale Offer shall cease to accrue interest (including Revenue Participation Interest) after the Proceeds Purchase Date; (5) that Holders electing to have a Note purchased pursuant to an Asset Sale Offer will be required to surrender the Note, with the form entitled "Option of Holder to Elect Purchase" on the reverse of the Note completed, to the Paying Agent at the address specified in the notice prior to the close of business on the third Business Day prior to the Proceeds Purchase Date; (6) that Holders will be entitled to withdraw their election if the Paying Agent receives, not later than five Business Days prior to the Proceeds Purchase Date, a telegram, telex, facsimile transmission or letter setting forth the name of the Holder, the principal amount of the Notes the Holder delivered for purchase and a statement that such Holder is withdrawing such Holder's election to have such Note purchased; and (7) that Holders whose Notes are purchased only in part will be issued new Notes in a principal amount equal to the unpurchased portion of the Notes surrendered; provided that each Note purchased and each new Note issued shall be in an original principal amount of $1,000 or integral multiples thereof. On or before the Proceeds Purchase Date, the Company shall (i) accept for payment Notes or portions thereof tendered pursuant to the Asset Sale Offer which are to be purchased in accordance with item (b)(1) above, (ii) deposit with the Paying Agent in U.S. dollars, an amount sufficient to pay the purchase price plus accrued interest (including Revenue Participation Interest, if any) and Liquidated Damages (if any) of all Notes to be purchased and (iii) deliver to the Trustee Notes so accepted together with an Officers' Certificate stating the Notes or portions thereof being purchased by the Issuers. The Paying Agent shall promptly mail to the Holders of Notes so accepted payment in an amount equal to the purchase price plus accrued interest (including Revenue Participation Interest, if any) and Liquidated Damages, if any. For purposes of this Section 4.15, the Trustee shall act as the Paying Agent. 41 46 Any amounts remaining after the purchase of Notes pursuant to an Asset Sale Offer shall be returned by the Trustee to the Company. The Company shall comply with the requirements of Rule 14e-1 under the Exchange Act and any other securities laws and regulations thereunder to the extent such laws and regulations are applicable in connection with the repurchase of Notes pursuant to an Asset Sale Offer. To the extent that the provisions of any securities laws or regulations conflict with this Section 4.15, the Company shall comply with the applicable securities laws and regulations and shall not be deemed to have breached its obligations under Section 4.15 by virtue thereof. (c) The foregoing provisions shall not apply to the sale, lease, conveyance or other disposition of all or substantially all of the assets of either of the Issuers, OCC or Teleglobe Mobile, which shall be governed by the provisions of Article V. SECTION 4.16. LIMITATION ON LIENS. The Credit Parties shall not, and shall not cause or permit any of its Subsidiaries to, directly or indirectly, create, incur, assume or suffer to exist any Lien on any asset of any of the Credit Parties whether owned on the Issue Date or acquired after the Issue Date, or any income or profits therefrom, or assign or convey any right to receive income therefrom, except Permitted Liens. SECTION 4.17. ADDITIONAL SUBSIDIARY GUARANTEES. In the event: (i) the Credit Parties or any other Guarantor shall transfer or cause to be transferred, in one transaction or a series of related transactions, any assets, businesses, divisions or other property having a book value determined in accordance with GAAP or a Fair Market Value which, when aggregated with all Investments described in clause (vii) of the definition of "Permitted Investment," would be in excess of the greater of (x) $5 million or (y) 5% of the System Consolidated Net Worth as of the date of transfer to any Restricted Subsidiary that is not a Subsidiary Guarantor; (ii) the Credit Parties or any other Guarantor shall acquire another Restricted Subsidiary with assets having either a book value determined in accordance with GAAP or a Fair Market Value which, when aggregated with all Investments described in clause (vii) of the definition of "Permitted Investment," would be in excess of the greater of (x) $5 million or (y) or 5% of the System Consolidated Net Worth as of the date on which any such acquisition is consummated; or (iii) at any time after the Issue Date, Restricted Subsidiaries of the Credit Parties and any Guarantors which are not Subsidiary Guarantors shall, in the aggregate, hold, own or otherwise control assets, businesses, divisions or property having either a book value determined in accordance with GAAP or a Fair Market Value which, when aggregated with all Investments described in clause (vii) of the definition of "Permitted Investment," would be in excess of the greater or (x) $5 million or (y) 5% of the System Consolidated Net Worth as of any date, then, in each such case, the Credit Parties or the Guarantor shall cause such Restricted Subsidiary or any number of Restricted Subsidiaries, as the case may be, to (i) execute and deliver to the Trustee a supplemental indenture in form reasonably satisfactory to the Trustee pursuant to which such Restricted Subsidiary shall unconditionally guarantee all of the Company's obligations under the Notes and this Indenture on the terms set forth in this Indenture and (ii) deliver to the Trustee an Opinion of Counsel that such supplemental indenture has been duly authorized, executed and delivered by such Restricted Subsidiary and constitutes a legal, valid, binding and enforceable obligation of such Subsidiary. Thereafter, such Restricted Subsidiary shall be a Guarantor for all purposes of this Indenture. SECTION 4.18. CONDUCT OF BUSINESS. The Credit Parties shall not, and shall not permit any of their Restricted Subsidiaries to, engage in any businesses other than that which is related to the design, development, procurement, installation, marketing and operation of telecommunications systems and businesses. Capital shall not own any operating assets or other property or conduct any business other than to serve as Issuer and obligor with respect to the Notes. 42 47 SECTION 4.19. PARTNERS' CONTINGENT COMMITMENT. In the event (a "Contingency Event") that (i) at least 20 satellites have not been placed in commercial service by December 31, 1998 and (ii) the Company's existing levels of cash and cash equivalents are less than $25 million (the amount of any such shortfall at any time prior to the Initial Deployment Date (as defined below) being referred to as the "Deficiency Amount"), then the Company shall draw-down on the Partners' Contingent Commitment from time to time after the Contingency Event through the date the Company has 20 satellites in commercial operation (the "Initial Deployment Date"). The Company shall maintain the Partners' Contingent Commitment in full force and effect from the Issue Date through the Initial Deployment Date (and the Partners' Contingent Commitment thereafter shall expire) and the Company shall enforce all obligations under such Partners' Contingent Commitment in accordance with their terms. Following the Initial Deployment Date, Teleglobe and Orbital shall be permitted to receive a distribution equal to the unused portion of any amounts drawn under the Partners' Contingent Commitment. SECTION 4.20. CONTINGENCY FUND. The Company shall establish a segregated account with a recognized financial institution and shall deposit $13 million into such account from the proceeds of the Notes (the "Contingency Fund"). The Company shall not expend monies in the Contingency Fund unless and until it has already expended all of the remaining proceeds of the offering of the Notes, and shall only expend monies in the Contingency Fund to fund development and deployment of the ORBCOMM System and related operating expenses. The Company may invest amounts in such segregated account comprising the Contingency Fund in cash or Cash Equivalents in accordance with the terms hereof. SECTION 4.21. METLIFE SEGREGATED ACCOUNT. Promptly following the Issue Date, the Company shall establish a segregated account with a recognized financial institution and shall deposit into such account from the proceeds of the Notes an amount sufficient to pay in full when due all remaining scheduled interest and principal payments on the MetLife Note. Interest earned on such account shall be payable to the Company. In the event the funds held in such segregated account exceed the amount sufficient to provide for payment in full of the principal of and interest on the MetLife Note, the Company shall be permitted to receive from such segregated account any such excess amount. At all times that the Company is complying with the terms of this Section 4.21, amounts outstanding under the MetLife Note shall not constitute Indebtedness and amounts held in such segregated account shall not constitute assets of any Credit Party hereunder. ARTICLE 5. MERGER, CONSOLIDATION OR SALE OF ASSETS SECTION 5.1. MERGERS, CONSOLIDATIONS AND CERTAIN SALES OF ASSETS. (a) Neither the Credit Parties nor any Guarantor (to the extent not permitted by the sale provisions under Article X) may, in a single transaction or a series of related transactions, consolidate or merge with or into (whether or not any such Credit Party or such Guarantor, as the case may be, is the surviving Person), or sell, assign, transfer, lease, convey or otherwise dispose of all or substantially all of its properties or assets in one or more related transactions to, another Person (other than any consolidation or merger of a Credit Party or Guarantor with or into, or the sale, assignment, transfer, lease, conveyance or disposal by a Credit Party or Guarantor to, any other Credit Party or Guarantor), unless: (i) such Credit Party or Guarantor, as the case may be, is the surviving Person or the Person formed by or surviving any such consolidation or merger (if other than such Credit Party or Guarantor, as the case may be) or to which such sale, assignment, transfer, lease, conveyance or other disposition shall have been made is a corporation organized and existing under the laws of the United States, any state thereof or the District of Columbia; 43 48 (ii) the Person formed by or surviving any such consolidation or merger (if other than such Credit Party or Guarantor, as the case may be) or the entity or Person to which such sale, assignment, transfer, lease, conveyance or other disposition shall have been made assumes all the obligations of such Credit Party or Guarantor, as the case may be, under the Notes, this Indenture, the Pledge Agreement and the Guarantees pursuant to a supplemental indenture in form reasonably satisfactory to the Trustee; (iii) immediately after such transaction, no Default or Event of Default exists; (iv) such Credit Party or Guarantor, as the case may be, or the Person formed by or surviving any such consolidation or merger (if other than such Credit Party or Guarantor, as the case may be) or to which such sale, assignment, transfer, lease, conveyance or other disposition shall have been made will have Consolidated Net Worth immediately after the transaction equal to or greater than the Consolidated Net Worth of such Credit Party or such Guarantor immediately preceding the transaction; (v) the Issuers will, at the time of such transaction and after giving pro forma effect thereto as if such transaction had occurred at the beginning of the immediately preceding fiscal quarter, be permitted to incur at least $1.00 of additional Indebtedness pursuant to the Indebtedness to Cash Flow Ratio set forth in the first paragraph of Section 4.12; (vi) each Guarantor, unless it is the other party to the transaction, shall have by supplemental indenture in form and substance satisfactory to the Trustee confirmed that after consummation of such transaction its Guarantee shall apply, as such Guarantee applied on the date it was granted, to the obligations of the Issuers under this Indenture and the Notes; and (vii) such Credit Party or Guarantor, as the case may be, and the surviving entity, shall have delivered to the Trustee an Officers' Certificate and an Opinion of Counsel, each stating that such consolidation, merger, sale, assignment, transfer, lease, conveyance or other disposition and, if a supplemental indenture is required in connection with such transaction, such supplemental indenture, comply with all applicable provisions of this Indenture and that all conditions precedent in this Indenture relating to such transaction have been satisfied. (b) For purposes of the foregoing, the transfer (by lease, assignment, sale or otherwise, in a single transaction or series of transactions) of all or substantially all of the properties or assets of one or more Subsidiaries of the Issuers, the Capital Stock of which constitutes all or substantially all of the properties and assets of such Issuer, shall be deemed to be the transfer of all or substantially all of the properties and assets of such Issuer.

ARTICLE 6. EVENTS OF DEFAULT AND REMEDIES SECTION 6.1. EVENTS OF DEFAULT. "Event of Default", wherever used herein, means any one of the following events (whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body): 44 49 (i) default for 30 days in the payment when due of interest (including Revenue Participation Interest, if any) on, or Liquidated Damages (if any) with respect to, the Notes;

or (b) results in the acceleration (which acceleration has not been rescinded) of such Indebtedness prior to its express maturity, and, in each case described in clause (a) and (b) of this paragraph, the principal amount of any such Indebtedness, together with the principal amount of any other such Indebtedness under which there has been a Payment Default or the maturity of which has been so accelerated, aggregates $5 million or more;

(vii) breach by the Issuers of any representation or warranty set forth in the Pledge Agreement, or default by the Issuers in the performance of any covenant set forth in the Pledge Agreement, or repudiation by the Issuers of any of their obligations under the Pledge Agreement or the unenforceability of the Pledge Agreement against the Issuers for any reason which in any one case or in the aggregate results in a material impairment of the rights intended to be afforded thereby; (viii) termination or loss, for any reason, of the FCC License; provided, however, that the transfer of the FCC License to any of the Credit Parties shall not constitute an Event of Default; (ix) the entry by a court having jurisdiction in the premises of (A) a decree or order for relief in respect of any Issuer, Guarantor, Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary, in an involuntary case or proceeding under any applicable Federal or state bankruptcy, insolvency, reorganization or other similar law or (B) a decree or order adjudging any Issuer, Guarantor, Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary, a bankrupt or insolvent, or approving as properly filed a petition seeking reorganization, arrangement, adjustment or composition of or in respect of any Issuer, Guarantor, Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary, under any applicable Federal or state law, or appointing a custodian, receiver, liquidator, assignee, trustee, sequestrator or other similar official of any Issuer, Guarantor, Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would 45 50 constitute a Significant Subsidiary, or of any substantial part of its property, or ordering the winding up or liquidation of its affairs, and the continuance of any such decree or order for relief or any such other decree or order unstayed and in effect for a period of 60 consecutive days; (x) the commencement by any Issuer, Guarantor, Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary, of a voluntary case or proceeding under any applicable Federal or state bankruptcy, insolvency, reorganization or other similar law or of any other case or proceeding to be adjudicated a bankrupt or insolvent, or the consent by it to the entry of a decree or order for relief in respect of any Issuer, Guarantor, Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary, in an involuntary case or proceeding under any applicable Federal or state bankruptcy, insolvency, reorganization or other similar law or to the commencement of any bankruptcy or insolvency case or proceeding against it, or the filing by it of a petition or answer or consent seeking reorganization or relief under any applicable Federal or state law, or the consent by it to the filing of such petition or to the appointment of or taking possession by a custodian, receiver, liquidator, assignee, trustee, sequestrator or other similar official of any Issuer, Guarantor, Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary, or of any substantial part of its property, or the making by it of an assignment for the benefit of creditors, or the admission by it in writing of its inability to pay its debts generally as they become due, or the taking of corporate action by any Issuer, Guarantor, Significant Subsidiary or any group of Restricted Subsidiaries that, taken together, would constitute a Significant Subsidiary, in furtherance of any such action; or (xi) any Guarantee of the Notes shall be held in a judicial proceeding to be unenforceable or invalid or shall cease for any reason to be in full force and effect, or any Guarantor, or any Person acting on behalf of any Guarantor, shall deny or disaffirm its obligations under its Guarantee of any Notes. SECTION 6.2. ACCELERATION. (a) If an Event of Default, other than an Event of Default specified in Section 6.1(ix) or (x), occurs and is continuing and has not been waived pursuant to Section 6.4, then the Trustee or the Holders of at least 25% in principal amount of outstanding Notes may declare the principal of and accrued interest (including Revenue Participation Interest, if any) and Liquidated Damages (if any) on all the outstanding Notes to be due and payable by notice in writing to the Issuers and the Trustee specifying the respective Event of Default, such notice to be deemed a "notice of acceleration" (the "Acceleration Notice"), and the same shall become immediately due and payable. (b) If an Event of Default specified in Section 6.1(ix) or (x) occurs and is continuing, then all unpaid principal of, and premium (if any) and accrued and unpaid interest (including Revenue Participation Interest, if any) and Liquidated Damages (if any) on all of the outstanding Notes shall ipso facto become and be immediately due and payable without any declaration or further act or notice on the part of the Trustee or any Holder. (c) At any time after a declaration of acceleration with respect to the Notes in accordance with Section 6.2(a), the Holders of a majority in principal amount of the Notes may rescind and cancel such declaration and its consequences, but only: (i) if the rescission would not conflict with any judgment or decree, (ii) if all existing Events of Default have been cured or waived except nonpayment of principal or interest (including Revenue Participation Interest, if any) or Liquidated Damages (if any) that has become due solely because of the acceleration, (iii) to the extent the payment of such interest is lawful, interest on overdue installments of interest (including Revenue Participation Interest, if any) and overdue principal, which has become due otherwise than by such declaration of acceleration, has been paid, (iv) if the Issuers have paid the Trustee its reasonable compensation and reimbursed the Trustee for its expenses, disbursements and advances and all other amounts due the Trustee pursuant to Section 7.7, and (v) if the Trustee shall have received an Officers' Certificate that such Event of Default has been cured or waived. No such rescission shall affect any subsequent Default or impair any right consequent thereto. (d) In the case of any Event of Default occurring by reason of any willful action (or inaction) taken 46 51 (or not taken) by or on behalf of the Issuers with the intention of avoiding payment of the premium that the Issuers would have had to pay if the Issuers then had elected to redeem the Notes pursuant to the optional redemption provisions of this Indenture, an equivalent premium shall also become and be immediately due and payable upon the acceleration of the Notes pursuant to Section 6.1(a) or (b). If an Event of Default occurs prior to August 15, 2001 by reason of any such willful action (or inaction) by or on behalf of the Issuers with the intention of avoiding the prohibition on redemption of the Notes prior to August 15, 2001, then the premium specified herein shall also become immediately due and payable to the extent permitted by law upon the acceleration of the Notes pursuant to Section 6.2(a) or (b). SECTION 6.3. OTHER REMEDIES. If an Event of Default occurs and is continuing, the Trustee may pursue any available remedy by proceeding at law or in equity to collect the payment of principal or premium (if any) of or interest (including Revenue Participation Interest, if any) or Liquidated Damages (if any) on the Notes or to enforce the performance of any provision of the Notes or this Indenture. The Trustee may maintain a proceeding even if it does not possess any of the Notes or does not produce any of them in the proceeding. A delay or omission by the Trustee or any Holder in exercising any right or remedy accruing upon an Event of Default shall not impair the right or remedy or constitute a waiver of or acquiescence in the Event of Default. No remedy is exclusive of any other remedy. All available remedies are cumulative to the extent permitted by law. SECTION 6.4. WAIVER OF PAST DEFAULTS. Subject to Sections 2.9, 6.7 and 9.2, the Holders of not less than a majority in principal amount of the outstanding Notes, by notice to the Trustee, may waive an existing Default or Event of Default and its consequences, except a Default in the payment of principal or premium (if any) of or interest (including Revenue Participation Interest, if any) or Liquidated Damages (if any) on any Note as specified in clauses (i) and (ii) of Section 6.1. SECTION 6.5. CONTROL BY MAJORITY. Subject to Section 2.9, the Holders of a majority in principal amount of the outstanding Notes may direct the time, method and place of conducting any proceeding for any remedy available to the Trustee or exercising any trust or power conferred on it, including, without limitation, any remedies provided for in Section 6.3. Subject to Section 7.1, however, the Trustee may refuse to follow any direction that the Trustee reasonably believes conflicts with any law or this Indenture or that the Trustee determines may be unduly prejudicial to the rights of another Holder. Notwithstanding any provision to the contrary herein, the Trustee shall not be obligated to take any action with respect to the provisions of Section 6.2(d) unless directed to do so pursuant to this Section 6.5. SECTION 6.6. LIMITATION ON SUITS. A Holder may not pursue any remedy with respect to this Indenture or the Notes unless: (a) the Holder gives to the Trustee written notice of a continuing Event of Default; (b) Holders of at least 25% in principal amount of the outstanding Notes make a written request to the Trustee to pursue the remedy; (c) such Holders offer to the Trustee indemnity reasonably satisfactory to the Trustee against any loss, liability or expense to be incurred in compliance with such request; (d) the Trustee does not comply with the request within 60 days after receipt of the request and the offer of satisfactory indemnity; and 47 52 (e) during such 60-day period the Holders of a majority in principal amount of the outstanding Notes do not give the Trustee a direction which, in the opinion of the Trustee, is inconsistent with the request. The foregoing limitations shall not apply to a suit instituted by a Holder for the enforcement of the payment of principal and premium (if any) or interest (including Revenue Participation Interest, if any) and Liquidated Damages (if any) on such Note on or after the respective due dates set forth in such Note (including upon acceleration thereof) or the institution of any proceeding with respect to this Indenture or any remedy hereunder, including, without limitation, acceleration, by the Holders of a majority in principal amount of outstanding Notes, provided that upon institution of any proceeding or exercise of any remedy, such Holders provide the Trustee with prompt notice thereof. A Holder may not use this Indenture to prejudice the rights of another Holder or to obtain a preference or priority over such other Holder, it being understood and intended that no one or more Holders shall have any right by virtue of any provision of this Indenture to affect, disturb or prejudice the rights of any other Holders, or to obtain or to seek to obtain priority or preference over any other Holders, or to enforce any right under this Indenture except in the manner herein provided and for the equal and ratable benefit of all the Holders. SECTION 6.7. RIGHTS OF HOLDERS TO RECEIVE PAYMENT. Notwithstanding any other provision of this Indenture, the right of any Holder to receive payment of principal of, and interest (including Revenue Participation Interest, if any) and Liquidated Damages (if any) on a Note, on or after the respective due dates expressed in such Note, or to bring suit for the enforcement of any such payment on or after such respective dates, shall not be impaired or affected without the consent of such Holder. SECTION 6.8. COLLECTION SUIT BY TRUSTEE. If an Event of Default in payment of principal or interest (including Revenue Participation Interest, if any) or Liquidated Damages (if any) specified in clause (i) or (ii) of Section 6.1 occurs and is continuing, the Trustee is authorized to recover judgment in its own name and as trustee of an express trust against the Issuers or any other obligor on the Notes for the whole amount of principal and accrued interest (including Revenue Participation Interest, if any) remaining unpaid and Liquidated Damages, if any, together with interest on overdue principal and, to the extent that payment of such interest is lawful, interest on overdue installments of interest, and such further amount as shall be sufficient to cover the costs and expenses of collection, including the reasonable compensation, expenses, disbursements and advances of the Trustee, its agents and counsel and all other amounts due to the Trustee pursuant to Section 7.7. SECTION 6.9. TRUSTEE MAY FILE PROOFS OF CLAIM. The Trustee may file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for the reasonable compensation, expenses, taxes, disbursements and advances of the Trustee, its agents and counsel and all other amounts due to the Trustee pursuant to Section 7.7) and the Holders allowed in any judicial proceedings relating to the Issuers or any other obligor upon the Notes, any of their respective creditors or any of their respective property and shall be entitled and empowered to collect and receive any monies or other property payable or deliverable on any such claims and to distribute the same, and any custodian, receiver, assignee, trustee, liquidator or other similar official in any such judicial proceedings is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amount due to it for the reasonable compensation, expenses, taxes, disbursements and advances of the Trustee, its agent and counsel, and any other amounts due the Trustee under Section 7.7. The Company's payment obligations to the Trustee under this Section 6.9 shall be secured in accordance with the provisions of Section 7.7. Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the 48 53 Notes or the rights of any Holder thereof, or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding. SECTION 6.10. PRIORITIES. If the Trustee collects any money or property pursuant to this Article VI, it shall pay out the money in the following order: First: to the Trustee for amounts due under Section 7.7; Second: if the Holders are forced to proceed against the Company directly without the Trustee, to the Holders for their collection costs; Third: to Holders for amounts due and unpaid on the Notes for principal and premium (if any) and interest (including Revenue Participation Interest, if any) and Liquidated Damages (if any), ratably, without preference or priority of any kind, according to the amounts due and payable on the Notes for principal and premium, and interest (including Revenue Participation Interest, if any) and Liquidated Damages, respectively; and Fourth: to the Issuers, the Guarantors or any other obligor on the Notes, as their interests may appear, or as a court of competent jurisdiction may direct. The Trustee, upon prior notice to the Company, may fix a record date and payment date for any payment to Holders pursuant to this Section 6.10. SECTION 6.11. UNDERTAKING FOR COSTS. In any suit for the enforcement of any right or remedy under this Indenture or in any suit against the Trustee for any action taken or omitted by it as Trustee, a court in its discretion may require the filing by any party litigant in the suit of an undertaking to pay the costs of the suit, and the court in its discretion may assess reasonable costs, including reasonable attorneys' fees, against any party litigant in the suit, having due regard to the merits and good faith of the claims or defenses made by the party litigant. This Section 6.11 does not apply to a suit by the Trustee, a suit by a Holder pursuant to Section 6.7, or a suit by a Holder or Holders of more than 10% in principal amount of the outstanding Notes.

(b) If a Default or an Event of Default has occurred and is continuing, the Trustee shall exercise such of the rights and powers vested in it by this Indenture and use the same degree of care and skill in its exercise thereof as a prudent person would exercise or use under the circumstances in the conduct of his own affairs.

(f) The Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request, order or direction of any of the Holders pursuant to the provisions of this Indenture including, without limitation, the provisions of Section 6.5 hereof, unless such Holders shall have offered to the Trustee security or indemnity reasonably satisfactory to the Trustee against the costs, expenses and liabilities which may be incurred by it in compliance with such request, order or direction. (g) The Trustee shall not be required to give any bond or surety in respect of the performance of its powers and duties hereunder.

INDIVIDUAL RIGHTS OF TRUSTEE AND AGENTS. Each of the Trustee, any Paying Agent and any Registrar, in its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with the Issuers, the Guarantors, or any of their respective Subsidiaries or Affiliates with the same rights it would have if it were not Trustee or such agent. SECTION 7.4. TRUSTEE'S DISCLAIMER. The Trustee makes no representation as to the validity or adequacy of this Indenture, the Pledge Agreement, the Pledged Securities or the Notes, and it shall not be accountable for the Issuers' use of the proceeds from the Notes, and it shall not be responsible for any statement of the Issuers in this Indenture or the Notes, other than the Trustee's certificate of authentication. SECTION 7.5. NOTICE OF DEFAULT. If a Default or an Event of Default occurs and is continuing and if it is known to the Trustee, the Trustee shall mail to each Holder notice of the uncured Default or Event of Default within 30 days after such Default or Event of Default becomes known to the Trustee. Except in the case of a Default or an Event of Default in payment of principal of, premium, if any, interest (including Revenue Participation Interest, if any) or Liquidated Damages (if any) on any Note, including an accelerated payment and the failure to make payment on the Change of Control Payment Date pursuant to a Change of Control Offer or on to the Proceeds Purchase Date pursuant to an Asset Sale Offer, and, except in the case of a failure to comply with Article V hereof, the Trustee may withhold the notice if and so long as it in good faith determines that withholding such notice is in the interest of the Holders. SECTION 7.6. REPORTS BY TRUSTEE TO HOLDERS. Within 60 days after each May 15, the Trustee shall, to the extent that any of the events described in TIA Section 313(a) occurred within the previous twelve months, but not otherwise, mail to each Holder a report dated as of such date that complies with TIA Section 313(a).

A copy of each report at the time of its mailing to Holders shall be mailed to the Issuers and filed with the Commission and each securities exchange, if any, on which the Notes are listed. The Company shall promptly notify the Trustee if the Notes become listed on any securities exchange and the Trustee shall comply with TIA Section 313(d). SECTION 7.7. COMPENSATION AND INDEMNITY. (a) The Issuers agree: (i) to pay to the Trustee from time to time reasonable compensation for all services rendered by it hereunder (which compensation shall not be limited by any provision of law in regard to the compensation of a trustee of an express trust); (ii) except as otherwise expressly provided herein, to reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with any provision of this Indenture (including the reasonable compensation and the expenses and disbursements of its agents and counsel), except any such expense, disbursement or advance as may be attributable to its negligence or bad faith; and (iii) to indemnify the Trustee for, and to hold it harmless against, any loss, liability or expense (including the reasonable compensation, expenses and disbursements of its agents, accountants, experts and counsel) incurred without negligence or bad faith on its part, arising out of or in connection with the 51 56 acceptance or administration of this trust, including the costs and expenses of enforcing this Indenture against the Issuers (including, without limitation, this Section 7.7) and of defending itself against any claim (whether asserted by any Holder or the Issuers) or liability in connection with the exercise or performance of any of its powers or duties hereunder. (b) The Trustee shall notify the Issuers promptly of any claim asserted against the Trustee for which it may seek indemnity. Failure by the Trustee to so notify the Issuers shall not relieve the Issuers of their obligations hereunder.

(d) To secure the Issuers' payment obligations in this Section 7.7, the Trustee shall have a lien prior to the Notes on all assets or money held or collected by the Trustee, in its capacity as Trustee, except assets or money held in trust to pay principal of, or interest (including Revenue Participation Interest, if any) or Liquidated Damages (if any) on, particular Notes.

(b) The Trustee may resign at any time by giving at least 30 days' advance written notice thereof to the Issuers. If an instrument of acceptance by a successor Trustee shall not have been delivered to the Trustee within 30 days after the giving of such notice of resignation, the resigning Trustee may petition any court of competent jurisdiction for the appointment of a successor Trustee. (c) The Trustee may be removed at any time by notice, in writing, of the Holders of a majority in principal amount of the outstanding Notes, delivered to the Trustee and to the Issuers.

If, within one year after such resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee shall be appointed by Act of the Holders of a majority in principal amount of the outstanding Notes delivered to the Issuers and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment, become the successor Trustee and supersede the successor Trustee appointed by the Issuers. If no successor Trustee shall have been so appointed by the Issuers or the Holders and accepted appointment in the manner herein provided, any Holder may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee. (f) If the Trustee, after written request by the Issuer or by any Holder who has been a Holder for at least six months, fails to comply with Section 7.11 hereof, such Holder may petition any court of competent jurisdiction for the removal of the Trustee or the appointment of a successor Trustee. (g) The Issuers shall give or cause to be given notice of each resignation and each removal of the Trustee and each appointment of a successor Trustee to all Holders in the manner provided herein. Each notice shall include the name of the successor Trustee and the address of its Corporate Trust Office. SECTION 7.9. ACCEPTANCE OF APPOINTMENT BY SUCCESSOR. Every successor Trustee appointed hereunder shall execute, acknowledge and deliver to the Issuers and to the retiring Trustee a written instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee. Upon request of the Issuers or the successor Trustee, the retiring Trustee shall execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder, in each case subject to the lien of the retiring Trustee granted pursuant hereto. Upon request of any such successor Trustee, the Issuers shall execute any and all instruments for more fully and certainly vesting in and confirming to such successor Trustee all such rights, powers and trusts. No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified and eligible under this Article VII. SECTION 7.10. SUCCESSOR TRUSTEE BY MERGER, ETC. If the Trustee consolidates with, merges or converts into, or transfers all or substantially all of its corporate trust business to, another corporation, the resulting, surviving or transferee corporation without any further act shall, if such resulting, surviving or transferee corporation is otherwise eligible hereunder, be the successor Trustee, provided that such corporation shall be otherwise qualified and eligible under this Article VII. In case any Notes shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Notes so authenticated with the same effect as if such successor Trustee had itself authenticated such Notes. SECTION 7.11. TRUSTEE REQUIRED; ELIGIBILITY; DISQUALIFICATION. There shall at all times be a Trustee hereunder which shall be a Person that is eligible pursuant to the TIA to act as such, and has a combined capital and surplus of at least $50,000,000 and its Corporate Trust Office in the Borough of Manhattan, The City of New York, New York. If such Person publishes reports of condition at least annually, pursuant to law or to the requirements of a Federal, state, territorial or District of Columbia supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Person shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section, it shall resign 53 58 immediately in the manner and with the effect specified in this Article VII. If the Trustee has or shall acquire a conflicting interest within the meaning of the TIA, the Trustee shall either eliminate such interest or resign, to the extent and in the manner provided by, and subject to the provisions of, the TIA and this Indenture. SECTION 7.12. PREFERENTIAL COLLECTION OF CLAIMS AGAINST ISSUERS. If and when the Trustee shall be or become a creditor of either of the Issuers (or any other obligor upon the Notes), the Trustee shall be subject to the provisions of the TIA regarding the collection of claims against such Issuer (or any such other obligor). ARTICLE 8. DEFEASANCE AND SATISFACTION AND DISCHARGE SECTION 8.1. SECTION 8.1. DEFEASANCE AND COVENANT DEFEASANCE. (a) Issuers' Option to Effect Defeasance or Covenant Defeasance. The Issuers may at their option, by an appropriate partnership or board resolution evidenced by an Officers' Certificate, at any time (subject to 10-day prior written notification to the Trustee), elect to have the provisions of either Section 8.1(b) or (c) applied to the outstanding Notes upon compliance with the conditions set forth below in this Article VIII. (b) Defeasance and Discharge. Upon the Issuers' exercise of the option provided in Section 8.1(a) applicable to this Section, the Issuers and the Guarantors shall be deemed to have been discharged from their obligations with respect to the outstanding Notes on the date the conditions set forth below are satisfied (hereinafter, "Defeasance"). For this purpose, such Defeasance means that the Issuers shall be deemed to have paid and discharged the entire indebtedness represented by the outstanding Notes and to have satisfied all their other obligations under such Notes and this Indenture insofar as such Notes are concerned (and the Trustee, at the expense of the Issuers, shall execute proper instruments acknowledging the same), except for the following which shall survive until otherwise terminated or discharged hereunder: (i) the rights of Holders of outstanding Notes to receive, solely from the trust fund described in Section 8.1(d) and as more fully set forth in such Section, payments in respect of the principal and premium (if any) of and interest (including Revenue Participation Interest, if any) and Liquidated Damages (if any) on such Notes when such payments are due, (ii) the Issuers' and the Guarantors' obligations with respect to such Notes under Sections 2.4, 2.6, 2.7, 2.10 and 4.2, (iii) the rights, powers, trusts, duties and immunities of the Trustee hereunder and (iv) this Article VIII. Subject to compliance with this Article VIII, the Issuers may exercise their option under this Section 8.1(b) notwithstanding the prior exercise of their option under Section 8.1(c). (c) Covenant Defeasance. Upon the Issuers' exercise of the option provided in Section 8.1(a) applicable to this Section, (i) the Issuers and the Guarantors shall be released from their obligations under Sections 4.5 through 4.18, inclusive and (ii) the occurrence of an event specified in Section 6.1(iv) shall not be deemed to be an Event of Default, on and after the date the conditions set forth below are satisfied (hereinafter, "Covenant Defeasance"). For this purpose, such Covenant Defeasance means that the Issuers may omit to comply with and shall have no liability in respect of any term, condition or limitation set forth in any such covenant, whether directly or indirectly by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other document, but the remainder of this Indenture and such Notes shall be unaffected thereby.

SECTION 8.2. SATISFACTION AND DISCHARGE. In addition to the Issuers' rights under Section 8.1, the Issuers may terminate all of their obligations under this Indenture, and the obligations of the Guarantors shall terminate (subject to Section 8.3), when: (a) all Notes theretofore authenticated and delivered (other than Notes which have been destroyed, lost or stolen and which have been replaced or paid as provided in Section 2.7 and Notes for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Issuers and thereafter repaid to the Issuers or discharged from such trust) have been delivered to the Trustee for cancellation or all such Notes not theretofore delivered to the Trustee for cancellation have become due and payable and the Issuers have irrevocably 55 60 deposited or caused to be deposited with the Trustee as trust funds in trust solely for that purpose an amount of money sufficient to pay and discharge the entire principal and premium (if any) of and interest (including Revenue Participation Interest, if any) and Liquidated Damages (if any) on the Notes not theretofore delivered to the Trustee for cancellation; (b) the Issuers have paid or caused to be paid all other sums payable hereunder; (c) the Issuers have delivered irrevocable instructions to the Trustee to apply the deposited money toward the payment of the Notes at maturity or redemption, as the case may be; and (d) the Issuers have delivered to the Trustee an Officers' Certificate and an Opinion of Counsel, stating that all conditions precedent specified herein relating to the satisfaction and discharge of this Indenture have been complied with.

SECTION 8.5. APPLICATION OF TRUST MONEYS AND GOVERNMENT SECURITIES. Subject to the provisions of Section 2.4, all money and Government Securities (including the proceeds thereof) deposited with the Trustee pursuant to Section 8.1(d)(i) in respect of the Notes shall be held in trust and applied by the Trustee, in accordance with the provisions of such Notes and this Indenture, to the payment, either directly or through any Paying Agent as the Trustee may determine, to the Holders of such Notes, of all sums due and to become due thereon in respect of principal and premium (if any) of and interest (including Revenue Participation Interest, if any) and Liquidated Damages (if any) on the Notes, but such money and Government Securities need not be segregated from other funds except to the extent required by law.

Anything in this Article VIII to the contrary notwithstanding, the Trustee shall deliver or pay to the Issuers from time to time upon request by an Officers' Certificate any money or Government Securities held by it as provided in Section 8.1(d)(i) which, in the opinion of a nationally recognized firm of independent certified public accountants expressed in a written certification thereof delivered to the Trustee, are in excess of the amount thereof which would then be required to be deposited to effect an equivalent defeasance or covenant defeasance. 56 61 SECTION 8.6. REPAYMENT TO THE ISSUERS OR THE GUARANTORS; UNCLAIMED MONEY.

If the Trustee or the Paying Agent is unable to apply any money or Government Securities in accordance with Section 8.1(b) or 8.1(c) by reason of any order or judgment of any court or governmental authority enjoining, restraining or otherwise prohibiting such application, then the Issuers' and the Guarantors' obligations under this Indenture and the Notes shall be revived and reinstated as though no deposit had occurred pursuant to this Article VIII until such time as the Trustee or Paying Agent is permitted to apply all such money or Government Securities in accordance with Section 8.1(b) or 8.1(c); provided, however, that if the Issuers or the Guarantors make any payment of principal and premium (if any) on any Note following the reinstatement of their obligations, the Issuers and the Guarantors shall be subrogated to the rights of the Holders of such Notes to receive such payment from the money held by the Trustee or the Paying Agent.

No amendment, supplement or waiver, including a waiver pursuant to Section 6.4, shall, without the consent of each Holder of each Note affected thereby: (1) reduce the principal amount of Notes whose Holders must consent to an amendment, supplement or waiver of any provision of this Indenture, the Notes, the Guarantee or the Pledge Agreement; (2) reduce the rate of or change or have the effect of changing the time for payment of any interest (including Revenue Participation Interest, if any) on any Note; (3) reduce the principal of or change or have the effect of changing the fixed maturity of any Note, or change the date on which any Notes may be subject to redemption, or reduce the redemption price therefor; (4) make any Note payable in money other than that stated in the Notes; (5) make any change in provisions of this Indenture relating to waivers of past Defaults or the rights of Holders of Notes to receive payments of principal and premium (if any) of, and interest (including Revenue Participation Interest, if any) or Liquidated Damages (if any) on, the Notes; (6) waive a Default or Event of Default in the payment of principal and premium (if any) of, and interest (including Revenue Participation Interest, if any) or Liquidated Damages (if any) on, the Notes (except a recision of acceleration of the Notes by the Holders of at least a majority in aggregate principal amount of the Notes and a waiver of the payment default that resulted from such acceleration); (7) waive a redemption payment with respect to any Note (other than a payment required by Section 4.14 and 4.15); (8) release any Guarantor from any of its obligations under its Guarantee or this Indenture otherwise than in accordance with the terms of this Indenture; or (9) make any change in the amendment and waiver provisions of this Section 9.2. 58 63 Upon the request of the Issuers accompanied by an Officers' Certificate in form satisfactory to the Trustee certifying corporate or partnership resolutions, as the case may be, authorizing the execution of any amended or supplemental Indenture, and upon the filing with the Trustee of evidence satisfactory of the consent of the Holders as aforesaid, and upon receipt by the Trustee of the documents described in Section 11.5 hereof, the Trustee shall join with the Issuers in the execution of such amended or supplemental Indenture unless such amended or supplemental Indenture affects the Trustee's own rights, duties or immunities under this Indenture or otherwise, in which case the Trustee may in its discretion, but shall not be obligated to, enter into such amended or supplemental Indenture. It shall not be necessary for the consent of the Holders under this Section to approve the particular form of any proposed amendment, supplement or waiver, but it shall be sufficient if such consent approves the substance thereof. After an amendment, supplement or waiver under this Section 9.2 becomes effective, the Company shall mail to the Holders affected thereby a notice briefly describing the amendment, supplement or waiver. Any failure of the Company to mail such notice, or any defect therein, shall not, however, in any way impair or affect the validity of any such supplemental indenture. SECTION 9.3. EXECUTION OF SUPPLEMENTAL INDENTURES. In executing, or accepting the additional trusts created by, any supplemental indenture permitted by this Article IX or the modifications thereby of the trusts created by this Indenture, the Trustee shall be entitled to receive, and (subject to Section 7.1) shall be fully protected in relying upon, in addition to the documents required by Section 11.5, an Opinion of Counsel stating that the execution of such supplemental indenture is authorized or permitted by this Indenture. The Trustee may, but shall not be obligated to, enter into any such supplemental indenture which affects the Trustee's own rights, duties or immunities under this Indenture or otherwise. SECTION 9.4. EFFECT OF SUPPLEMENTAL INDENTURES. Upon the execution of any supplemental indenture under this Article IX, this Indenture shall be modified in accordance therewith, and such supplemental indenture shall form a part of this Indenture for all purposes; and every Holder of Notes theretofore or thereafter authenticated and delivered hereunder shall be bound thereby. SECTION 9.5. COMPLIANCE WITH TRUST INDENTURE ACT. Every amendment, waiver or supplement of this Indenture or the Notes shall comply with the TIA as then in effect. SECTION 9.6. REFERENCE IN NOTES TO SUPPLEMENTAL INDENTURES. Notes authenticated and delivered after the execution of any supplemental indenture pursuant to this Article IX may, and shall if required by the Trustee, bear a notation in form approved by the Trustee as to any matter provided for in such supplemental indenture. If the Issuers shall so determine, new Notes so modified as to conform, in the opinion of the Trustee and the Issuers, to any such supplemental indenture may be prepared and executed by the Issuers and authenticated and delivered by the Trustee in exchange for outstanding Notes. SECTION 9.7. REVOCATION AND EFFECT OF CONSENTS. Until an amendment, waiver or supplement becomes effective, a consent to it by a Holder is a continuing consent by the Holder and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder's Note, even if notation of the consent is not made on any Note. Subject to the following paragraph, any such Holder or subsequent Holder may revoke the consent as to such Holder's Note or portion of such Note by notice to the Trustee or the Issuers received before the date on which the Trustee receives an Officers' 59 64 Certificate certifying that the Holders of the requisite principal amount of Notes have consented (and not theretofore revoked such consent) to the amendment, supplement or waiver. The Issuers may, but shall not be obligated to, fix a record date for the purpose of determining the Holders entitled to consent to any amendment, supplement or waiver, which record date , if so fixed, shall be fixed pursuant to Section 11.7(e) hereof. After an amendment, supplement or waiver becomes effective, it shall bind every Holder, unless it makes a change described in any of clauses (1) through (9) of Section 9.2, in which case, the amendment, supplement or waiver shall bind only each Holder of a Note who has consented to it and every subsequent Holder of a Note or portion of a Note that evidences the same debt as the consenting Holder's Note; provided that any such waiver shall not impair or affect the right of any Holder to receive payment of principal of, and interest (including Revenue Participation Interest) and Liquidated Damages (if any) on, a Note, on or after the respective due dates expressed in such Note, or to bring suit for the enforcement of any such payment on or after such respective dates without the consent of such Holder. ARTICLE 10. GUARANTEE SECTION 10.1. UNCONDITIONAL GUARANTEE. Each Guarantor hereby fully and unconditionally guarantees, jointly and severally, to each Holder of a Note authenticated and delivered by the Trustee and to the Trustee and its successors and assigns, irrespective of the validity and enforceability of this Indenture or the Notes or the obligations of the Guarantors under this Indenture or the Notes that: (i) the principal of and premium (if any) and interest (including Revenue Participation Interest, if any) and Liquidated Damages (if any) on the Notes will be paid in full when due, subject to any applicable grace period, whether at maturity, by acceleration or otherwise and interest on the overdue principal, if any, and interest on any interest (including Revenue Participation Interest, if any), to the extent lawful, on the Notes and all other obligations of the Issuers to the Holders or the Trustee hereunder or thereunder will be promptly paid in full or performed, all in accordance with the terms hereof and thereof; and (ii) in case of any extension of time of payment or renewal of any Notes or of any such other obligations, the same will be paid in full when due or performed in accordance with the terms of the extension or renewal, subject to any applicable grace period, whether at stated maturity, by acceleration or otherwise, subject, however, in the case of clauses (i) and (ii) above, to the limitations set forth in Section 10.5. Each Guarantor hereby agrees that its obligations hereunder shall be unconditional, irrespective of the validity, or enforceability of the Notes or this Indenture, the absence of any action to enforce the same, any waiver or consent by any Holder of the Notes with respect to any provisions hereof or thereof, the recovery of any judgment against the Issuers, any action to enforce the same or any other circumstance which might otherwise constitute a legal or equitable discharge or defense of a guarantor. Each Guarantor hereby waives diligence, presentment, demand of payment, filing of claims with a court in the event of insolvency or bankruptcy of the Issuers, any right to require a proceeding first against the Issuers, protest, notice and all demands whatsoever and covenants that this Guarantee will not be discharged (except to the extent released pursuant to Section 8.1) except by complete performance of the obligations contained in the Notes, this Indenture and in this Guarantee. If any Holder or the Trustee is required by any court or otherwise to return to the Issuers, any Guarantor, or any custodian, trustee, liquidator or other similar official acting in relation to the Issuers or any Guarantor, any amount paid by the Issuers or any Guarantor to the Trustee or such Holder, this Guarantee, to the extent theretofore discharged, shall be reinstated in full force and effect (except to the extent released pursuant to Section 8.1). Each Guarantor further agrees that, as between each Guarantor, on the one hand, and the Holders and the Trustee, on the other hand, (x) the maturity of the obligations guaranteed hereby may be accelerated as provided in Article VI for the purposes of this Guarantee, notwithstanding any stay, injunction or other prohibition preventing such acceleration in respect of the obligations guaranteed hereby, and (y) in the event of any acceleration of such obligations as provided in Article VI, such obligations (whether or not due and payable) shall forthwith become due and payable by each Guarantor for the purpose of this Guarantee. 60 65 SECTION 10.2. PRIORITY OF GUARANTEE. The obligations of each Guarantor to the Holders of Notes and to the Trustee pursuant to this Guarantee and this Indenture will rank senior in right and priority of payment to all other indebtedness of such Guarantor that is expressly subordinated to this Guarantee and will rank pari passu in right and priority of payment with all other indebtedness of such Guarantor that is not expressly so subordinated to such Guarantee, except to the extent of any collateral securing such other indebtedness. SECTION 10.3. SEVERABILITY. In case any provision of this Guarantee shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired thereby. SECTION 10.4. RELEASE OF A SUBSIDIARY GUARANTOR. Upon the sale or disposition (whether by merger, stock purchase, asset sale or otherwise) of a Subsidiary Guarantor (or all or substantially all its assets) to a Person which is not a Subsidiary of the Company and which sale or disposition is otherwise in compliance with the terms of this Indenture, such Subsidiary Guarantor shall be deemed released from all obligations under this Article X without any further action required on the part of the Trustee or any Holder. The Trustee shall deliver an appropriate instrument evidencing such release upon receipt of a request by the Issuers accompanied by an Officers' Certificate and Opinion of Counsel certifying as to the compliance with this Section. Any Subsidiary Guarantor not so released shall remain liable for the full amount of principal of and interest (including Revenue Participation Interest) and Liquidated Damages (if any) on the Notes as provided in this Article X. SECTION 10.5. LIMITATION OF SUBSIDIARY GUARANTOR'S LIABILITY. Each Subsidiary Guarantor, and by its acceptance hereof each Holder, hereby confirms that it is the intention of all such parties that the guarantee by such Subsidiary Guarantor pursuant to Section 10.1 not constitute a fraudulent transfer or conveyance for purposes of the Bankruptcy Law, the Uniform Fraudulent Conveyance Act, the Uniform Fraudulent Transfer Act or any similar Federal or state law. To effectuate the foregoing intention, the Holders and each Subsidiary Guarantor hereby irrevocably agree that the obligations of such Subsidiary Guarantor under its Guarantee shall be limited to the maximum amount as will, after giving effect to all other contingent and fixed liabilities of such Subsidiary Guarantor, and after giving effect to any collections from or payments made by or on behalf of any other Subsidiary Guarantor in respect of the obligations of such other Subsidiary Guarantor under its Guarantee or pursuant to Section 10.6, result in the obligations of such Subsidiary Guarantor under this Guarantee not constituting such fraudulent transfer or conveyance. SECTION 10.6. CONTRIBUTION. In order to provide for just and equitable contribution among the Subsidiary Guarantors, the Subsidiary Guarantors agree, inter se, that in the event any payment or distribution is made by any Subsidiary Guarantor (a "Funding Guarantor") under this Guarantee, such Funding Guarantor shall be entitled to a contribution from all other Subsidiary Guarantors in a pro rata amount based on the Adjusted Net Assets of each Subsidiary Guarantor (including the Funding Guarantor) for all payments, damages and expenses incurred by that Funding Guarantor in discharging the Issuers' obligations with respect to the Notes or any other Subsidiary Guarantor's obligations with respect to this Guarantee. "Adjusted Net Assets" of such Subsidiary Guarantor at any date shall mean the lesser of the amount by which (x) the fair value of the property of such Subsidiary Guarantor exceeds the total amount of liabilities, including, without limitation, contingent liabilities (after giving effect to all other fixed and contingent liabilities incurred or assumed on such date (other than liabilities of such Subsidiary Guarantor under Indebtedness of such Subsidiary Guarantor that is subordinated in right of payment to this Guarantee of such Subsidiary Guarantor)), but excluding liabilities under this Guarantee, of such Subsidiary Guarantor at such date and (y) the 61 66 present fair salable value of the assets of such Subsidiary Guarantor at such date exceeds the amount that will be required to pay the probable liability of such Subsidiary Guarantor on its debts (after giving effect to all other fixed and contingent liabilities incurred or assumed on such date and after giving effect to any collection from any Subsidiary of such Subsidiary Guarantor in respect of the obligations of such Subsidiary under this Guarantee), excluding debt in respect of this Guarantee of such Subsidiary Guarantor, as they become absolute and matured. SECTION 10.7. WAIVER OF SUBROGATION. Until all Obligations are paid in full each Guarantor hereby irrevocably waives any claim or other rights which it may now or hereafter acquire against the Issuers that arise from the existence, payment, performance or enforcement of such Guarantor's obligations under this Guarantee and this Indenture, including, without limitation, any right of subrogation, reimbursement, exoneration, indemnification, and any right to participate in any claim or remedy of any Holder of Notes against the Issuers, whether or not such claim, remedy or right arises in equity, or under contract, statute or common law, including, without limitation, the right to take or receive from the Company, directly or indirectly, in cash or other property or by set-off or in any other manner, payment or security on account of such claim or other rights. If any amount shall be paid to any Guarantor in violation of the preceding sentence and the Notes shall not have been paid in full, such amount shall have been deemed to have been paid to such Guarantor for the benefit of, and held in trust for the benefit of, the Holders of the Notes, and shall forthwith be paid to the Trustee for the benefit of such Holders to be credited and applied upon the Notes, whether matured or unmatured, in accordance with the terms of this Indenture. Each Guarantor acknowledges that it will receive direct and indirect benefits from the financing arrangements contemplated by this Indenture and that the waiver set forth in this Section 10.7 is knowingly made in contemplation of such benefits. SECTION 10.8. EXECUTION OF GUARANTEE. This Indenture shall evidence the Guarantee to the Holders as set forth in this Article X. Each Guarantor hereby certifies that this Guarantee has been duly authorized by all requisite partnership or corporate action, as the case may be, and that the execution and delivery of this Indenture to the Trustee shall constitute due delivery of such Guarantee on behalf of such Guarantor. SECTION 10.9. WAIVER OF STAY, EXTENSION OR USURY LAWS. Each Guarantor covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law or any usury law or other law that would prohibit or forgive each such Guarantor from performing its Guarantee as contemplated herein, wherever enacted, now or at any time hereafter in force, or which may affect the covenants or the performance of this Indenture, and (to the extent that it may lawfully do so) each such Guarantor hereby expressly waives all benefit or advantage of any such law, and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted. SECTION 10.10. OBLIGATIONS OF THE GUARANTORS UNCONDITIONAL. Nothing contained in this Indenture is intended to or shall impair, as between the Guarantors and the Holders, the obligation of the Guarantors, which is absolute and unconditional, to pay to the Holders all amounts due and payable under the Guarantees as and when the same shall become due and payable in accordance with their terms, or is intended to or shall affect the relative rights of the Holders and creditors of the Guarantors, nor shall anything herein or therein prevent the Trustee or any Holder from exercising all remedies otherwise permitted by applicable law upon default under this Indenture in respect of cash, property or securities of the Guarantors received upon the exercise of any such remedy. Upon any payment or distribution of assets of any Guarantor referred to in this Article X, the Trustee and the Holders shall be entitled to rely upon any order or decree made by any court of competent jurisdiction in which any dissolution, winding up, liquidation or reorganization proceedings are pending, or a certificate of the receiver, trustee in bankruptcy, liquidating trustee or agent or other Person making any payment or distribution to the Trustee or to the Holders for the purpose of ascertaining the Persons entitled to 62 67 participate in such payment or distribution, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article X. ARTICLE 11. MISCELLANEOUS SECTION 11.1. TRUST INDENTURE ACT CONTROLS. If any provision of this Indenture limits, qualifies or conflicts with a provision of the TIA that is required under the TIA to be a part of and govern this Indenture, such required provision shall control. If any provision of this Indenture modifies or excludes any provision of the TIA that may be so modified or excluded, the provision of the TIA shall be deemed to apply to this Indenture as so modified or excluded, as the case may be. SECTION 11.2. NOTICES TO ISSUERS AND TRUSTEE. Any notices or other communications required or permitted hereunder shall be in writing, and shall be sufficiently given if made by hand delivery, by facsimile, or by registered or certified mail, postage prepaid, return receipt requested, and addressed as follows: If to the Issuers or the c/o ORBCOMM Global, L.P.

SECTION 11.3. NOTICES TO HOLDERS. Where this Indenture provides for notice to Holders, such notice shall be sufficiently given (unless otherwise herein expressly provided) if in writing and: (i) in the case of a Global Note, by facsimile or by overnight 63 68 mail to the Depository; and (ii) in the case of securities other than a Global Note, by first-class mail, postage prepaid, in each case to each Holder affected at his address as it appears in the Note Register, and shall be sufficiently given if sent not later than the latest date (if any) and not earlier than the earliest date (if any) prescribed for the giving of such notice. Neither the failure to mail any such notice nor any defect in any notice so mailed to any particular Holder shall affect the sufficiency of such notice with respect to other Holders. Notice may be waived in writing by any Person entitled to receive such notice, either before or after the event requiring notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver. SECTION 11.4. TRUSTEE, PAYING AGENT AND REGISTRAR PROCEDURES. The Trustee may make reasonable rules in accordance with the Trustee's customary practices for action by or at meetings of Holders, and the Paying Agent and the Registrar may make reasonable rules for their functions. SECTION 11.5. COMPLIANCE CERTIFICATES AND OPINIONS. (a) Upon any application or request by the Issuers to the Trustee to take any action under any provision of this Indenture, the Issuers shall furnish to the Trustee such certificates and opinions as may be required under the TIA and under this Indenture. Each such certificate or opinion required to be made under this Indenture shall be given in the form of an Officers' Certificate, if to be given by the Issuers, or an Opinion of Counsel, if to be given by counsel, and shall comply with the requirements of the TIA and any other requirement set forth in this Indenture. (b) Every certificate or opinion with respect to compliance with a condition or covenant provided for in this Indenture shall include: (i) a statement that each individual signing such certificate or opinion has read such covenant or condition and the definitions herein relating thereto; (ii) a brief statement as to the nature and scope of the examination or investigation upon which the statements or opinions contained in such certificate or opinion are based; (iii) a statement that, in the opinion of each such individual, he has made such examination or investigation as is necessary to enable him to express an informed opinion as to whether or not such covenant or condition has been complied with; and (iv) a statement as to whether, in the opinion of each such individual, such condition or covenant has been complied with. SECTION 11.6. FORM OF DOCUMENTS DELIVERED TO TRUSTEE. (a) In any case where several matters are required to be certified by, or covered by an opinion of, any specified Person, it is not necessary that all such matters be certified by, or covered by the opinion of, only one such Person, or that they be so certified or covered by only one document, but one such Person may certify or give an opinion with respect to some matters and one or more other such Persons as to other matters, and any such Person may certify or give an opinion as to such matters in one or several documents. (b) Any Officers' Certificate may be based, insofar as it relates to legal matters, upon an Opinion of Counsel submitted therewith, unless such officer knows, or in the exercise of reasonable care should know, that the opinion with respect to the matters upon which his certificate is based is erroneous. Any Opinion of Counsel may be based, insofar as it relates to factual matters, upon a certificate of officers of the Issuers submitted therewith stating the information on which such counsel is relying, unless such counsel knows, or in the exercise of reasonable care should know, that the certificate with respect to such matters is erroneous. 64 69 SECTION 11.7. ACTS OF HOLDERS; REGISTERED HOLDERS; RECORD DATES. (a) Any request, demand, authorization, direction, notice, consent, waiver or other action provided by this Indenture to be given or taken by Holders may be embodied in and evidenced by one or more written instruments of substantially similar tenor signed by such Holders in person or by agent duly appointed in writing; and, except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments are delivered to the Trustee and, where it is hereby expressly required, to the Issuers. Such instrument or instruments (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the "Act" of the Holders signing such instrument or instruments. Proof of execution of any such instrument or of a writing appointing any such agent shall be sufficient for any purpose of this Indenture and (subject to Section 7.1) conclusive in favor of the Trustee and the Issuers, if made in the manner provided in this Section. (b) The fact and date of the execution by any Person of any such instrument or writing pursuant to this Section may be proved by the affidavit of a witness of such execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to him the execution thereof. Where such execution is by a signer acting in a capacity other than his individual capacity, such certificate or affidavit shall also constitute sufficient proof of his authority. The fact and date of the execution of any such instrument or writing, or the authority of the Person executing the same, may also be proved in any other manner which the Trustee deems sufficient. (c) The ownership of Notes shall be proved by the Note Register. (d) Any request, demand, authorization, direction, notice, consent, waiver or other Act of the Holder of any Note shall bind every future Holder of the same Note and the Holder of every Note issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee or the Issuers in reliance thereon, whether or not notation of such action is made upon such Note. (e) The Issuers may set any day as a record date for the purpose of determining the Holders of outstanding Notes entitled to give, make or take any request, demand, authorization, direction, notice, consent, waiver or other action provided or permitted by this Indenture to be given, made or taken by Holders of Notes; provided that the Issuers may not set a record date for, and the provisions of this paragraph shall not apply with respect to, the giving or making of any notice, declaration, request or direction referred to in paragraph (f) below. If not set by the Issuers prior to the first solicitation of a Holder made by any Person in respect of any such matter referred to in the foregoing sentence, the record date for any such matter shall be the 30th day (or, if later, the date of the most recent list of Holders required pursuant to Section 2.5) prior to such first solicitation. If any record date is set pursuant to this paragraph, the Holders of outstanding Notes on such record date, and no other Holders, shall be entitled to take the relevant action, whether or not such Holders remain Holders after such record date. Nothing in this paragraph shall be construed to prevent the Issuers from setting a new record date for any action for which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall automatically and with no action by any Person be cancelled and of no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by Holders of the requisite principal amount of outstanding Notes on the date such action is taken. Promptly after any record date is set pursuant to this paragraph, the Issuers, at their own expense, shall cause notice of such record date, the proposed action by Holders to be given to the Trustee in writing and to each Holder of Notes in the manner set forth in Section 11.2. (f) The Trustee may set any day as a record date for the purpose of determining the Holders of outstanding Notes entitled to join in the giving or making of (i) any notice hereunder, (ii) any declaration of acceleration referred to in Section 6.2, (iii) any request to institute proceedings referred to in Section 6.6 or (iv) any direction referred to in Section 6.5. If any record date is set pursuant to this paragraph, the Holders of outstanding Notes on such record date, and no other Holders, shall be entitled to join in such notice, declaration, request or direction, whether or not such Holders remain Holders after such record date. Nothing in this paragraph shall be construed to prevent the Trustee from setting a new record date for any action for which a record date has previously been set pursuant to this paragraph (whereupon the record date previously set shall automatically and 65 70 with no action by any Person be cancelled and of no effect), and nothing in this paragraph shall be construed to render ineffective any action taken by Holders of the requisite principal amount of outstanding Notes on the date such action is taken. Promptly after any record date is set pursuant to this paragraph, the Trustee, at the Issuers' expense, shall cause notice of such record date, the proposed action by Holders to be given to the Issuers in writing and to each Holder of Notes in the manner set forth in Section 11.2. (g) Without limiting the foregoing, a Holder entitled hereunder to take any action hereunder with regard to any particular Note may do so with regard to all or any part of the principal amount of such Note or by one or more duly appointed agents each of which may do so pursuant to such appointment with regard to all or any part of such principal amount. SECTION 11.8. SUCCESSORS AND ASSIGNS. All covenants and agreements of the Issuers and the Guarantors in this Indenture, the Notes and the Guarantees shall bind their successors. All agreements of the Trustee in this Indenture shall bind its successors. SECTION 11.9. SEVERABILITY. In case any one or more of the provisions in this Indenture or in the Notes or in the Guarantees shall be held invalid, illegal or unenforceable in any jurisdiction, in any respect for any reason, the validity, legality and enforceability of any such provision in every other jurisdiction and in every other respect, and of the remaining provisions, shall not in any way be affected or impaired thereby, it being intended that all of the provisions hereof shall be enforceable to the full extent permitted by law. SECTION 11.10. BENEFITS OF INDENTURE. Nothing in this Indenture or in the Notes or in the Guarantees, express or implied, shall give to any Person, other than the parties hereto and their successors hereunder and the Holders of Notes, any benefit or any legal or equitable right, remedy or claim under this Indenture. SECTION 11.11. GOVERNING LAW; JURISDICTION. THIS INDENTURE, THE NOTES AND THE GUARANTEES SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK, AS APPLIED TO CONTRACTS MADE AND PERFORMED ENTIRELY WITHIN THE STATE OF NEW YORK, WITHOUT REGARD TO PRINCIPLES OF CONFLICT OF LAWS. EACH OF THE PARTIES HERETO AGREES TO SUBMIT TO THE JURISDICTION OF THE COURTS OF THE STATE OF NEW YORK IN ANY ACTION OR PROCEEDING ARISING OUT OF OR RELATING TO THIS INDENTURE. SECTION 11.12. LEGAL HOLIDAYS. In any case where any Interest Payment Date, Redemption Date, Proceeds Purchase Date or Change of Control Payment Date of any Note shall not be a Business Day, then, notwithstanding any other provision of this Indenture or of the Notes or the Guarantees, payment of interest (including Revenue Participation Interest, if any) or Liquidated Damages (if any) on or principal and premium (if any) of the Notes need not be made on such date, but may be made on the next succeeding Business Day with the same force and effect as if made on such Interest Payment Date, Redemption Date, Proceeds Purchase Date or Change of Control Payment Date, as the case may be. SECTION 11.13. NO RECOURSE AGAINST OTHERS; LIMITATION ON LIABILITY. Notwithstanding anything contained in this Indenture or the Notes to the contrary, (i) except for the Issuers and the Guarantors to the extent provided in clause (ii) below, no person or entity (including, without limitation, the past, present or future general, limited partners and/or shareholders of OCC and Teleglobe Mobile and the directors, 67 71 officers and employees of the Issuers and the Guarantors) shall have any liability whatsoever with respect to or arising out of this Indenture, the Notes, the Guarantees or any of the Issuers' or the Guarantors' obligations thereunder or any agreements or documents executed by the Issuers or the Guarantors in connection therewith and (ii) claims with respect to this Indenture, the Notes and the Guarantees and any obligations thereunder or under any agreements or documents executed in connection therewith shall be satisfied solely from the assets of the Issuers and the Guarantors. Each Holder, by accepting a Note, waives and releases all such liability. Such waiver and release are part of the consideration for the issuance of the Notes. SECTION 11.14. COUNTERPARTS. This Indenture may be executed in any number of counterparts, each of which so executed shall be deemed to be an original, but all such counterparts shall together constitute but one and the same instrument. 67 72 IN WITNESS WHEREOF, the parties hereto have caused this Amended Indenture to be duly executed as of the day and year first above written, ORBCOMM GLOBAL, L.P.

By: --------------------------------------- Name: Title: ORBCOMM GLOBAL CAPITAL CORP. By: --------------------------------------- Name: Title: Dated: ------------ A-2 75 Trustee's Certificate of Authentication This is one of the 14% Senior Notes due 2004 referred to in the within-mentioned Indenture. MARINE MIDLAND BANK, as Trustee By: ---------------------------------------- Authorized Signatory A-3 76 (REVERSE OF NOTE) 14% Senior Note due 2004 Capitalized terms used herein shall have the meanings ascribed to them in the Indenture (as defined below) unless otherwise indicated. 1. Interest. ORBCOMM Global, L.P., a Delaware limited partnership ("ORBCOMM"), and ORBCOMM Global Capital Corp., a Delaware corporation ("Capital" and, together with ORBCOMM, the "Issuers"), promise to pay interest on the principal amount of this Note at the rate per annum shown above. Interest on the Notes will accrue from the most recent date on which interest has been paid or, if no interest has been paid, from August 7, 1996. The Issuers will pay interest semi-annually in arrears on each Interest Payment Date, commencing February 15, 1997. Interest will be computed on the basis of a 360-day year of twelve 30-day months. The Issuers shall pay interest on overdue principal and on overdue installments of interest (including Revenue Participation Interest, if any) from time to time on demand at the rate borne by the Notes plus 1.0% per annum (without regard to any applicable grace periods) to the extent lawful. In addition, the Notes shall bear Revenue Participation Interest, calculated as described below, from the Issue Date to the date of payment of the Notes. Installments of Revenue Participation Interest accrued through the Accrual Period (as defined below) last ended or previously deferred shall become due and payable semi-annually on each February 15 and August 15 after the Issue Date, commencing on February 15, 1997, to the Holders of record at the close of business on the preceding February 1 or August 1. Additionally, all installments of accrued or deferred Revenue Participation Interest will become due and payable (and may not be further deferred) with respect to any principal amount of the Notes upon maturity (whether at stated maturity, upon acceleration, maturity of repurchase obligation or otherwise) of such principal amount of the Notes. The Issuers, at their option, may defer payment of all or a portion of Revenue Participation Interest then otherwise due if, and only to the extent that, (a) the payment of such portion of Revenue Participation Interest will cause the Credit Parties' Fixed Charge Coverage Ratio for the four consecutive fiscal quarters last completed prior to such interest payment date to be less than 2.0:1 on a pro forma basis after giving effect to the assumed payment of such Revenue Participation Interest (as if such payment were made during such four quarter period) (but may not defer such portion which, if paid, will not cause such Credit Parties' Fixed Charge Coverage Ratio to be less than 2.0:1); provided, however, that for purposes of calculating such Credit Parties' Fixed Charge Coverage Ratio for any period, (x) the amount representing Revenue Participation Interest that has been or will be deferred for such period shall not be included in the calculation of Credit Parties' Fixed Charges for such period and (y) the amount representing Revenue Participation Interest paid in such period (whether relating to such period or any prior period) shall be included in the calculation of Credit Parties' Fixed Charge Coverage for such period, and (b) the principal of the Notes corresponding to such Revenue Participation Interest has not then matured and become due and payable (at stated maturity, upon acceleration, upon maturity of repurchase obligation or otherwise). Revenue Participation Interest that is deferred shall become due and payable on the earlier of (i) the next succeeding Interest Payment Date on which such Revenue Participation Interest is not permitted to be deferred, and (ii) upon the maturity of the corresponding principal of the Notes (whether at stated maturity, upon acceleration, upon maturity of repurchase obligation or otherwise). No interest will accrue on any deferred Revenue Participation Interest that has not yet become due and payable. Each installment of Revenue Participation Interest will be calculated to accrue (an "Accrual Period") from, but not including, the most recent date through which Revenue Participation Interest has been paid or provided for or through which Revenue Participation Interest has been calculated and deferred (or from and including the Issue Date if no installment of Revenue Participation Interest has A-4 77 been paid, provided for or deferred) to, and including, either (a) the last day of the next Semi-annual Period if the corresponding principal of the Notes has not become due and payable (or December 31, 1996 if no installment of Revenue Participation Interest has been paid, provided for or deferred) or (b) the date of payment if the corresponding principal of the Notes has become due and payable (whether at stated maturity, upon acceleration, upon maturity of repurchase obligation or otherwise). With respect to each Accrual Period, Revenue Participation Interest will accrue daily on the principal of each Note outstanding during such period as follows: (i) for each day during each month that ends during such Accrual Period and which month ends at least 25 days prior to the date of payment, an amount equal to 1/30th of the Monthly Revenue Participation Interest on the Note for such month until all of such Monthly Revenue Participation Interest on the Note shall be accrued (and all of such month's Monthly Revenue Participation Interest on the Note shall be accrued by the last day of such month) and (ii) for any day in any remaining period, 1/30th of the prior month's Monthly Revenue Participation Interest on the Notes. For purposes hereof, "Monthly Revenue Participation Interest" means, with respect to any month and any Note, the product of 5.0% of System Revenue for such month times a fraction, the numerator of which is the principal amount outstanding on such Note and the denominator of which is $170,000,000. Any reference in this Note to "accrued and unpaid interest" includes the amount of unpaid Revenue Participation Interest and Liquidated Damages, if any, due and payable thereon. 2. Method of Payment. The Issuers shall pay interest (including Revenue Participation Interest, if any) on the Notes (except defaulted interest) and Liquidated Damages, if any, to the Persons who are the Holders at the close of business on the Record Date immediately preceding the Interest Payment Date even if the Notes are cancelled on registration of transfer or registration of exchange after such Record Date. Holders must surrender Notes to a Paying Agent to collect principal payments. The Issuers shall pay principal and interest in U.S. dollars. The Issuers may pay principal and interest by their check payable in such U.S. dollars or by wire transfer as provided in the Indenture. The Issuers may deliver any such interest payment to the Paying Agent or to a Holder at the Holder's registered address. 3. Paying Agent and Registrar. Initially, Marine Midland Bank, a New York banking corporation and trust company (the "Trustee", which term includes any successor trustee under the Indenture referred to below), will act as Paying Agent and Registrar. The Issuers may change the Paying Agent or Registrar without notice to or consent of the Holders. 4. Indenture and Guarantee. The Issuers issued the Note under an Indenture, dated as of August 7, 1996 (the "Indenture"), among the Issuers, Orbital Communications Corporation, a Delaware corporation ("OCC"), Teleglobe Mobile Partners, a Delaware general partnership ("Teleglobe Mobile"), ORBCOMM USA, L.P., a Delaware limited partnership ("USA"), and ORBCOMM International Partners, L.P., a Delaware limited partnership ("International" and, together with OCC, Teleglobe Mobile and USA, the "Guarantors"), and the Trustee.

The Holders of the Original Notes shall be entitled to receive certain additional interest payments in the event such exchange offer is not consummated and upon certain other conditions, all pursuant to and in accordance with the terms of the Registration Rights Agreement. 10.

Without notice to or consent of any Holder, the parties thereto may make such amendments or supplements to, among other things, cure any ambiguity, defect or inconsistency, provide for uncertificated Notes in addition to or in place of certificated Notes, comply with Article V of the Indenture (dealing with certain mergers and consolidations) or make any other change that does not adversely affect the legal rights of any Holder of a Note. 15.

The Indenture permits, subject to certain limitations therein provided, Holders of a majority in aggregate principal amount of the Notes then outstanding to direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of Notes notice of any continuing Default or Event of Default (except a Default in payment of principal of, or interest (including Revenue Participation Interest, if any) or Liquidated Damages, if any) payable on, the Notes if it determines that withholding notice is in the Holders' interest. 17.

No interest will accrue on any deferred Revenue Participation Interest that has not yet become due and payable. Each installment of Revenue Participation Interest will be calculated to accrue (an "Accrual Period") from, but not including, the most recent date through which Revenue Participation Interest has been paid or provided for or through which Revenue Participation Interest has been calculated and deferred (or from and including the Issue Date if no installment of Revenue Participation Interest has been paid, provided for or deferred) to, and including, either (a) the last day of the next Semi-annual Period if the corresponding principal of the Notes has not become due and payable (or December 31, 1996 if no installment of Revenue Participation Interest has been paid, provided for or deferred) or (b) the date of payment if the corresponding principal of the Notes has become B-3 88 due and payable (whether at stated maturity, upon acceleration, upon maturity of repurchase obligation or otherwise). With respect to each Accrual Period, Revenue Participation Interest will accrue daily on the principal of each Note outstanding during such period as follows: (i) for each day during each month that ends during such Accrual Period and which month ends at least 25 days prior to the date of payment, an amount equal to 1/30th of the Monthly Revenue Participation Interest on the Note for such month until all of such Monthly Revenue Participation Interest on the Note shall be accrued (and all of such month's Monthly Revenue Participation Interest on the Note shall be accrued by the last day of such month) and (ii) for any day in any remaining period, 1/30th of the prior month's Monthly Revenue Participation Interest on the Notes. For purposes hereof, "Monthly Revenue Participation Interest" means, with respect to any month and any Note, the product of 5.0% of System Revenue for such month times a fraction, the numerator of which is the principal amount outstanding on such Note and the denominator of which is $170,000,000. Any reference in this Note to "accrued and unpaid interest" includes the amount of unpaid Revenue Participation Interest and Liquidated Damages, if any, due and payable thereon. 6. Method of Payment. The Issuers shall pay interest (including Revenue Participation Interest, if any) on the Notes (except defaulted interest) and Liquidated Damages, if any, to the Persons who are the Holders at the close of business on the Record Date immediately preceding the Interest Payment Date even if the Notes are cancelled on registration of transfer or registration of exchange after such Record Date. Holders must surrender Notes to a Paying Agent to collect principal payments. The Issuers shall pay principal and interest in U.S. dollars. The Issuers may pay principal and interest by their check payable in such U.S. dollars or by wire transfer as provided in the Indenture. The Issuers may deliver any such interest payment to the Paying Agent or to a Holder at the Holder's registered address. 7. Paying Agent and Registrar. Initially, Marine Midland Bank, a New York banking corporation and trust company (the "Trustee", which term includes any successor trustee under the Indenture referred to below), will act as Paying Agent and Registrar. The Issuers may change the Paying Agent or Registrar without notice to or consent of the Holders. 8. Indenture and Guarantee. The Issuers issued the Note under an Indenture, dated as of August 7, 1996 (the "Indenture"), among the Issuers, Orbital Communications Corporation, a Delaware corporation ("OCC"), Teleglobe Mobile Partners, a Delaware general partnership ("Teleglobe Mobile"), ORBCOMM USA, L.P., a Delaware limited partnership ("USA"), and ORBCOMM International Partners, L.P., a Delaware limited partnership ("International" and, together with OCC, Teleglobe Mobile and USA, the "Guarantors"), and the Trustee. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust Indenture Act of 1939 (15 U.S. Code Sections 77aaa-77bbbb) (the "TIA"), as in effect on the date of the Indenture until such time as the Indenture is qualified under the TIA, and thereafter as in effect on the date on which the Indenture is qualified under the TIA. Notwithstanding anything to the contrary herein, the Notes are subject to all such terms, and Holders of Notes are referred to the Indenture and the TIA for a statement of such terms. The Notes are general obligations of the Issuers limited in aggregate principal amount to $170,000,000. Payment on each Note is guaranteed on an unsecured basis by the Guarantors pursuant to Article X of the Indenture. Each Holder, by accepting a Note, agrees to be bound by all of the terms and provisions of the Indenture, as the same may be amended from time to time. 9. Redemption. (a) Optional Redemption.

Notes to be redeemed shall cease to bear interest from and after the Redemption Date and the only right of the Holders of such Notes will be to receive payment of the Redemption Price plus accrued and unpaid interest (including Revenue Participation Interest, if any) and Liquidated Damages (if any). 12. Offers to Purchase. Sections 4.14 and 4.15 of the Indenture provide that, after certain Asset Sales and upon the occurrence of a Change of Control, and subject to the conditions and limitations contained therein, the Issuers will make an offer to purchase certain amounts of the Notes in accordance with the procedures set forth in the Indenture at a purchase price equal to 101% in the case of a Change of Control and 100% in the case of Asset Sales, of the principal amount thereof plus accrued and unpaid interest (including Revenue Participation Interest, if any) and Liquidated Damages (if any) to the date of purchase. 13. Denomination; Transfer; Exchange. The Notes are issued in fully registered form in denominations of $1,000 and integral multiples of $1,000. A Holder shall register any transfer or exchange of Notes in accordance with the Indenture. The Registrar may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay certain transfer taxes or similar governmental charges payable in connection therewith as provided in the Indenture. The Registrar need not register the transfer of or exchange of any Notes or portions thereof selected for redemption. 14. Persons Deemed Owners. The Holder of a Note shall be treated as the owner of such Note for all purposes. 15. Unclaimed Money. If money for the payment of principal or interest remains unclaimed for two years, the Trustee and the Paying Agent will pay the money back to the Issuers or the Guarantors, as the case may be, after which all liability of the Trustee and Paying Agent with respect to such money shall cease. 16. Discharge Prior to Redemption or Maturity. If the Issuers and/or the Guarantors at any time deposit with the Trustee U.S. dollars or Government Securities sufficient to pay the principal of and interest (including Revenue Participation Interest, if any, and Liquidated Damages, if any) on the Notes to redemption or maturity, and comply with the other provisions of the Indenture relating thereto, the Issuers and the Guarantors will be discharged from certain provisions of the Indenture and the Notes (including certain covenants, but excluding B-5 90 their obligation to pay the principal of, and interest (including Revenue Participation Interest, if any) and Liquidated Damages (if any) payable on, the Notes). 17. Amendment; Supplement; Waiver.

Without notice to or consent of any Holder, the parties thereto may make such amendments or supplements to, among other things, cure any ambiguity, defect or inconsistency, provide for uncertificated Notes in addition to or in place of certificated Notes, comply with Article V of the Indenture (dealing with certain mergers and consolidations) or make any other change that does not adversely affect the legal rights of any Holder of a Note. 18. Restrictive Covenants. The Indenture imposes certain limitations on the ability of the Issuers, the Guarantors and their Restricted Subsidiaries to, among other things, incur additional Indebtedness, pay dividends or make other distributions, repurchase Equity Interests, repay subordinated Indebtedness, make certain other Restricted Payments, create certain Liens, enter into certain transactions with Affiliates, sell assets, issue or sell Equity Interests of the Issuers' Restricted Subsidiaries, or enter into certain mergers or consolidations. Such limitations are subject to important qualifications and exceptions. The Issuers must annually report to the Trustee on compliance with such limitations. 19. Defaults and Remedies. If an Event of Default occurs and is continuing, the Trustee or the Holders of at least 25% in aggregate principal amount of Notes then outstanding may declare all the Notes to be due and payable in the manner, at the time and with the effect provided in the Indenture. Holders of Notes may not enforce the Indenture or the Notes except as provided in the Indenture. The Trustee is not obligated to enforce the Indenture or the Notes unless it has received security or indemnity reasonably satisfactory to the Trustee. The Indenture permits, subject to certain limitations therein provided, Holders of a majority in aggregate principal amount of the Notes then outstanding to direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of Notes notice of any continuing Default or Event of Default (except a Default in payment of principal of, or interest (including Revenue Participation Interest, if any) or Liquidated Damages, if any) payable on, the Notes if it determines that withholding notice is in the Holders' interest. 20. Individual Rights of Trustee. Each of the Trustee, the Paying Agent and the Registrar under the Indenture, in its individual or any other capacity, may become the owner or pledgee of Notes and may otherwise deal with the Issuers, the Guarantors or any of their respective Subsidiaries or Affiliates as if it were not the Trustee or such agent. 21. No Recourse Against Others; Limitation on Liability. Notwithstanding anything contained in the Indenture or the Notes to the contrary, (i) except for the Issuers and the Guarantors to the extent provided in clause (ii) below, no person or entity (including, without limitation, the past, present or future general and limited partners and/or shareholders of OCC and Teleglobe Mobile and the directors, officers and employees of the Issuers and the Guarantors) shall have any liability whatsoever with respect to or arising out of the Indenture, the Notes, the Guarantees or any of the Issuers' or the Guarantors' obligations thereunder or any agreements or documents executed by the Issuers or the Guarantors in connection therewith and (ii) claims with respect to the Indenture, the Notes and the Guarantees and any obligations thereunder or under any agreements or documents executed in connection therewith shall be satisfied solely from the assets of the Issuers and the Guarantors.
