NETWORK PRODUCTS PURCHASE AGREEMENT Northern Telecom Inc., a Delaware corporation having offices at 5555 Windward Parkway, Suite B, Alpharetta, Georgia 30201-3895 ("Nortel") and Teligent, Inc., a Virginia corporation, having its principal offices and place of business at 8065 Leesburg Pike, Suite 400, Vienna, Virginia 22182 ("Teligent") agree as follows: 1. SCOPE AND TERM 1.1 Certain terms used in this Agreement shall be defined as set forth in Attachment A. In the case of any conflict between the main text of this Agreement and the Attachments hereto, the main text shall govern. 1.2 Scope 1.2.1 This Agreement sets forth the terms and conditions under which Teligent shall purchase and/or license, as applicable, certain Deliverables as set forth herein. [redacted] [redacted] 1.3 This Agreement shall be binding on the Parties from the date executed, except that if on or prior to January 31, 1998 or such other date as Nortel and Teligent may mutually agree upon (the "Determination Date"), Nortel and Teligent have not entered into the Finance Agreement and the security documents contemplated thereby for any reason (a "Termination Event"), either Party shall have the right to terminate all the rights and obligations of both Parties under this Agreement, except those with respect to Core Deliverables ordered by Teligent, by delivery of five (5) days prior written notice of such termination. With respect to such Core Deliverables, Teligent may elect within fifteen (15) days after termination either (a) to keep the Core Deliverables, and in which case, Teligent shall pay Nortel for the purchase price of the Core Deliverables, less [redacted] and Nortel's support obligations shall survive and continue in full force and effect with respect to such Core Deliverables; or (b) to return the Core Deliverables, paying a re-stocking fee of [redacted] of the Core Deliverables returned. If Teligent shall fail to make any such election, Teligent shall be deemed to have elected to return the Core Deliverables to Nortel. Notwithstanding any election by Teligent to keep the Core Deliverables, Teligent may within fifteen (15) days after such election elect to return all Core Deliverables with respect to which it has not yet paid the reduced purchase price described in clause (a) above (such purchase price with respect to any item of Core Deliverables, the "Item Purchase Price") otherwise as provided in clause (b) above. If Teligent fails to pay the Item Purchase Price, or any portion thereof, for any item of Core Deliverables (each an "Item") within thirty (30) days after receipt of Notice from Nortel that such amounts were not paid when due, a "Return Event" shall be deemed to have occurred. At any time after the occurrence and during the continuation of a Return Event, Nortel may demand the return of the Item with respect to which such Return Event has occurred and Teligent shall promptly provide for the return of such Item to Nortel as provided below. Upon the return of any Item to Nortel, Nortel shall promptly refund to Teligent an amount equal to all payments received by it in respect of the Item Purchase Price for such Item [redacted] of such Item Purchase Price. If Teligent shall, for any reason, be required to return any Item under this Section 1. 3, Teligent shall make such Item available for return on the premises or facility where such Item is then located and Nortel shall be entitled to remove such Item during normal business hours or, if requested by Nortel, Teligent shall, at Nortel's sole expense, deliver such Item, or cause such Item to be delivered, to any location in the continental United States requested by Nortel. Except as expressly set forth in this Section 1.3, Teligent shall have no obligation or liability whatsoever in connection with the return of any Core Deliverables (including, without limitation, in connection with a Return Event) arising out of a Termination Event. Unless Teligent expressly elects to keep certain Core Deliverables as provided in this Section 1.3, nothing contained in this Section 1.3 or in Section 4.6 shall constitute, or be deemed to constitute, an obligation of Teligent to purchase any Item or to pay any purchase price in respect of an Item; provided, that if no Termination Event shall have occurred on or prior to the Determination Date, this Section 1.3 shall no longer apply and shall have no further effect. [redacted] [redacted] [redacted] 1.5 Turn-Key Services 1.5.1 Nortel shall offer Buyer the option to purchase from Nortel Services on both a full turn-key (including engineering services but excluding civil works) and a partial turn-key basis as set forth in the Statement of Work, attached hereto as Attachment H. 1.5.2 Buyer shall be responsible for any and all civil works required under this Agreement, including those set forth in the Buyer's Obligation Section of the Statement of Work, as set forth in Attachment H. Nortel and Buyer shall mutually agree upon civil works ready dates when developing detailed Core Deliverables schedules. 1.5.3 Nortel shall use only its own personnel or Nortel-qualified third-party service contractors and Nortel shall warrant their performance as set forth in Section 10. Buyer may reasonably request the removal of any Nortel personnel or third-party service contractor and Nortel shall promptly comply. 1.6 Nortel shall use all reasonable efforts to furnish and install Core Deliverables so that such Core Deliverables shall comply in all material respects with all federal, state and local laws and regulations in force on the date of execution of this Agreement, which directly impose obligations upon the manufacturer, seller or installer thereof. Notwithstanding the foregoing, Buyer acknowledges that certain Core Deliverables have not yet received required type approval from the Federal Communications Commission ("FCC"). Nortel's obligation to furnish Core Deliverables to Buyer is expressly conditioned upon Nortel or its Teligent-Approved Radio Vendor receiving FCC Core Deliverables type approval prior to delivery of such Core Deliverables, unless Buyer can reasonably demonstrate to Nortel that such type approval is not required for operation of such Core Deliverables by Buyer, (e.g., situations where Buyer operates the Core Deliverables under an FCC experimental license). The failure of Nortel or its Teligent-Approved Radio Vendor to receive necessary Core Deliverables type approval from the FCC and to meet other federal, state and local regulatory requirements shall be regarded as a Force Majeure event under Section 13 of this Agreement. Nortel warrants that it and its Teligent-Approved Radio Vendor are vigorously prosecuting the necessary FCC type-approval application(s). Any failure by Nortel or its Teligent-Approved Radio Vendor to use all reasonable efforts to obtain FCC Type-approval prior to the General Availability Dates for such Core Deliverables as specified in Attachment F shall be grounds for Material Breach and give rise to Teligent's right to terminate for cause. 1.7 Term 1.7.1 This Agreement shall be in effect on the date last executed and continue for a period of five (5) years thereafter ("Term"). This Agreement or any part thereof may be terminated in accordance with the express provisions of this Agreement concerning termination or by written agreement of the Parties. 1.7.2 The termination of this Agreement or any part thereof shall not affect the obligations of either Party thereunder which have not been fully performed with respect to any accepted Order, unless such Order is expressly terminated in accordance with this Agreement or by written agreement of the Parties. 2. PURCHASES OF CORE DELIVERABLES 2.1 Deliverables 2.1.1 For purposes of this Agreement, the definition of "Core Deliverables" shall mean any Services, Equipment and Software, including Radio Products, drawings, documents, manuals and training, supplied directly by Nortel including any equipment not Nortel-branded ("OEM Equipment"), even if such OEM Equipment is not part of Nortel's standard product offerings. 2.1.2 For purposes of this Agreement, the definition of "Adjunct Deliverables" shall mean any telecommunications support products supplied by third parties, including ancillary services, directly to Teligent that are in the categories described in Attachment E, attached hereto, and used in connection with Core Deliverables. Teligent shall have the right to acquire and install in its network any Adjunct Deliverable if it is compatible with the Core Deliverables and in compliance with industry standard interfaces, or if Teligent assumes the responsibility for such equipment's non-compliance. 2.1.3 Before procuring any Adjunct Deliverables, [redacted]. In the event Buyer purchases any Adjunct Deliverable from Nortel, such equipment shall be considered to be a Core Deliverable and not an Adjunct Deliverable. Nortel shall provide Buyer support of such equipment as if it were non-OEM Equipment Core Deliverables. 2.1.4 Teligent further agrees that by the end of the twelfth (12th) month from the effective date of this Agreement, as defined in Section 1.7.1 herein, at least [redacted] percent [redacted] of the total purchase price of Deliverables financed by Nortel shall be Core Deliverables. By the end of the [redacted] month of from the effective date of this Agreement and on an annual basis thereafter, Teligent agrees that at least [redacted] of the total purchase price of all Deliverables financed by Nortel from the effective date of this Agreement shall be Core Deliverables. These ratios shall include Core Deliverables then on order for delivery under the Standard Intervals set forth in Section 8. In the event that at the end of the [redacted] month from the effective date of this Agreement, and for any following [redacted] month period thereafter, Teligent has failed to purchase enough Core Deliverables to meet the above required percentages, then Teligent shall issue within ninety (90) days additional Orders for Core Deliverables for delivery within Standard Intervals sufficient so as to meet the required percentages. 2.2 Teligent-Approved Radio Vendor 2.2.1 Microwave transmission Products supplied as Core Deliverables shall be made only by Teligent- Approved Radio Vendors. Nortel shall be responsible for managing Teligent-Approved Radio Vendors in connection with this Agreement. [redacted] 2.2.3 The process for establishing other Teligent- Approved Radio Vendors shall be as follows: - In consultation with Teligent senior engineering staff, Nortel shall propose specific new Microwave Product(s) to add to the Core Deliverables in Attachment G, together with pricing and specifications therefor. - Teligent may elect to trial the equipment, with Nortel and the vendor of the proposed Product, according to mutually-agreed costs, tests and scheduling, or Teligent may reject the proposal. - If, based on the trial results and other investigation of the proposed vendor's processes and capabilities, Teligent is satisfied that the Product should be added to the Core Deliverables list, Teligent shall notify Nortel in writing that the vendor is a Teligent-Approved Radio Vendor for that Product and Attachment G shall accordingly be modified. - Teligent may refuse to certify a vendor or its product in its sole, reasonable discretion and shall provide Nortel the technical and business reasons for such refusal to certify. 2.2.4 If a Teligent-Approved Radio Vendor is added or dropped, the Parties recognize that changes may be necessary to various terms of this Agreement including the Future Deliverables set forth in Attachment F. The Parties shall negotiate in good faith on such changes. 3. FORECASTS, ORDERING AND ADMINISTRATION 3.1 Forecasts 3.1.1 Teligent hereby agrees that within one (1) week of the effective date of this Agreement, Teligent shall provide Nortel an initial forecast covering four (4) quarters of Core Deliverables to be purchased during the first year of this Agreement. Such initial forecast shall also include a firm Order for Teligent's Core Deliverables as required to be purchased under Section 3.1.2. 3.1.2 Teligent shall provide Nortel a rolling twelve (12) month forecast ("Yearly Forecast") covering Core Deliverables to be purchased. Such Yearly Forecast shall detail the Core Deliverables by product and quantities. Teligent shall update the Yearly Forecast on a quarterly basis. Teligent agrees that the first three (3) months of such Yearly Forecast of Core Deliverables shall represent a non-reducible binding purchase commitment, and at least fifty percent (50%) of the second three (3) months of each Yearly Forecast of Core Deliverables shall also be binding. 3.1.3 Nortel shall be obligated to deliver to Buyer up to one hundred ten percent (110%) of the first three (3) months of the Yearly Forecast for each type of Core Deliverable products, if ordered, in accordance with the Standard Intervals set forth in Section 8. Core Deliverables in excess of one hundred ten percent (110%) of the first three (3) months of the Yearly Forecast for such Core Deliverables shall be delivered in accordance with Nortel's usual delivery intervals or as mutually agreed by Nortel and Buyer. 3.2 Orders 3.2.1 All purchases of Core Deliverables pursuant to this Agreement shall be made by means of Orders issued from time to time by Buyer. Such Order shall be accepted or rejected by Nortel in writing within five (5) business days. If not expressly rejected, an acknowledged Order will be deemed accepted. All Orders shall reference this Agreement and shall be governed solely by the terms and conditions set forth herein. 3.2.2 When Buyer desires to order Core Deliverables, if any, Buyer shall submit to Nortel's designated representative as defined in Section 3.3, an Order which shall at a minimum specify the following, if applicable: (i) the name of the Buyer placing the Order; (ii) the types and quantities of Core Deliverables, if any, to be furnished by Nortel; (iii) the applicable prices, charges and fees with respect to such Core Deliverables, if any; (iv) the location or facility to which the Core Deliverables are to be delivered; (v) the incorporation by reference of this Agreement; (vi) the location at which the Core Deliverables are to be installed, if known; (vii) the requested delivery date and/or in- service date; (viii) any other information required under this Agreement to be included in an Order. 3.2.3 Orders shall specify if any Nortel installation Services are required, and Buyer shall provide Nortel all necessary information related to final delivery destination and such installation Services at least two (2) weeks prior to the delivery date set forth in such Order. 3.2.4 An Order submitted pursuant to this Agreement, and which Nortel has accepted, shall constitute a Contract between the Buyer ordering and Nortel. As long as this Agreement is effective, Nortel may only reject an Order if such Order is not in accordance with the provisions of Section 3.2.2 above, and in that event, Nortel shall specifically identify the precise reasons under which it rejects such Order. The foregoing does not limit any rights Nortel may have under Section 3.1.3. 3.2.5 Buyer may at any time request additions, alterations, deductions or deviations to an Order subject to the condition that such changes and any adjustments resulting from such changes including, but not limited to, schedules and prices, shall be mutually agreed upon and, if so agreed, subsequently detailed in a written revision to the applicable Order ("Change Order"). Buyer acknowledges that a premium charge may be applied by Nortel should Nortel agree to process a Change Order outside of its standard Order processing cycle for a Core Deliverable or in the event that a Change Order requires an additional amount of work (such as engineering) to be undertaken to comply with such changes. 3.2.6 Buyer's original Order for each new System shall be so identified. Buyer may place supplemental Orders amending the original Order for each System to add Node Equipment for sixty (60) days from the issuance of the original Order, and to add TAS equipment for ninety (90) days from the issuance of the original Order, as long as the TCO configuration is not changed, unless Nortel shall consent to any configuration change. All such Core Deliverables so ordered shall constitute the System. 3.3 Administration 3.3.1 Each Party shall delegate a Program Manager sufficient authority to administer day-to-day contract administration matters. 3.3.2 Five (5) business days prior to the submission of each quarterly forecast described in Section 3.1.2, Nortel's Program Manager shall submit to Buyer's Program Manager an "Issues and Status Report", identifying issues and matters requiring resolution from Nortel's perspective. Concurrently with the purchase forecasts described in Section 3.1.2, the Buyer's Program Manager shall submit to Nortel's Program Manager an "Issues and Status Report" identifying issues and matters requiring resolution from Buyer's perspective. Within ten (10) business days after receiving this report, both Program Managers shall jointly prepare a report confirming the current forecast and addressing the issues and matters identified in the two (2) reports, proposing specific steps to resolve them. These reports shall be prepared in a manner appropriate for submission to senior management responsible for oversight of the Parties' relationship. 4.

Any future features or functionality developed by Nortel for such Radio Products shall not be used as a basis for a price increase if they are: (a) not used by Buyer, or (b) beyond those identified in Attachment F if alternative Radio Products conforming to the features identified in Attachment F are not available from Nortel. 4.3.4 Buyer may request TCO pricing to include technical support services as set forth in Section 18.4 and Nortel shall offer Buyer TCO pricing including such technical support for a metropolitan area. 4.3.5 [redacted]. 4.4 [redacted] 4.5 Nortel will prepay freight charges and the cost of any insurance requested by Buyer and invoice Buyer for these items at Nortel's [redacted]. These charges will appear as separate line items on Nortel's invoice. 4.6 (a) In order to secure the Return Obligations (as defined below), Buyer hereby grants Nortel a security interest in all of its right, title and interest in and to any item of the Core Deliverables in which it has a right, title and interest. As used in the Section 4.6, "Return Obligations" shall mean the obligations of Teligent to provide for the return of Core Deliverables if a Termination Event shall have occurred and Teligent shall be required pursuant to Section 1.3 to return said Core Deliverables to Nortel. (b) The Buyer shall not sell, lease or otherwise dispose of any such item of Core Deliverables or any portion thereof, except, (i) to any wholly-owned subsidiary of the Buyer or any affiliate of the Buyer that is wholly-owned by the parent of the Borrower, or (ii) without the prior written consent of Nortel. The Buyer shall not permit to exist any liens, security interests or other encumbrances ("Liens") on any item of Core Deliverables, possession of which has been delivered to the Buyer, other than (a) the Liens created or contemplated hereby, (b) Liens for taxes or assessments, (c) any Liens arising by statute or operation of law, (d) Liens of carriers, warehousemen, mechanics, materialmen and repairmen, (e) Liens contemplated by the Finance Agreement, and (f) and other non-consensual Liens arising in the ordinary course of business. (c) Buyer agrees to execute such documents and to take such other action reasonably requested by Nortel to perfect, maintain and preserve Nortel's security interest, including, without limitation, UCC financing statements. (d) If Teligent shall fail to provide for the return of any Core Deliverables as provided in Section 1.3 (a "Default"), Nortel shall have all of the rights and remedies of a secured party under the Uniform Commercial Code ("UCC") consistent with the nature of the Return Obligations. Upon the occurrence of a Default, without limiting the generality of the foregoing, to the extent permitted by, and in accordance with, all applicable laws, Nortel may without demand or notice to the Buyer, collect, receive or take possession of the Core Deliverables or any part thereof and for that purpose Nortel may enter upon any premises on which the Core Deliverables subject to such Default are located and remove the Core Deliverables subject to such Default therefrom. (e) Nortel's security interests in each item of Core Deliverables granted pursuant to Section 4.6(a) above (each such item, a "Secured Item", and such items collectively, the "Secured Items") shall continue until the earlier of (i) the purchase price of such Secured Item is paid, or has been deemed to be paid, in full and (ii) such Secured Item is required to be returned to Nortel pursuant to Section 1.3 and such Secured Item has been returned, at which time, with respect to such Secured Item, (A) the Buyer's obligations and Nortel's rights and remedies under this Section 4.6 shall terminate and be of no further effect, (B) Nortel's security interest in such Secured Item shall terminate and hereby is terminated, and (C) Nortel shall execute and deliver such documents and instruments and take such other actions as may be reasonably requested by Teligent or any lender under the Finance Agreement to effect or evidence the termination of the obligations and security interests under this Section 4.6, including, without limitation, UCC termination statements. In order to provide Teligent with more favorable terms under the Finance Agreement, upon the request of Teligent or any lender under the Finance Agreement, Nortel agrees that it shall use reasonable commercial efforts to accommodate the requests of Teligent or such lender with respect to the priority of its security interests in the Secured Items, and shall cooperate with Teligent and such lender in amending the provisions hereof on such terms as are mutually acceptable to all such Parties. 5. TERMS OF PAYMENT 5.1 Payments shall be due within [redacted] calendar days from the invoice receipt, but penalties for late payment shall not be assessed until [redacted] calendar days from invoice receipt. Past due amounts shall accrue interest at the lending rate made available to Teligent as in the Finance Agreement.

If Buyer can make beneficial use of the facilities in question, then Nortel shall be entitled to payment for those goods or services delivered and performed. 5.5 Where Core Deliverables that are part of a System Order have not been installed at the time of System ATP primarily due to circumstances within Buyer's control, then such Core Deliverables shall be deemed installed for purposes of invoicing and payment. 6. TAXES Unless Buyer furnishes Nortel with tax exemption certificates in a form acceptable to taxing authorities, Buyer shall, at Nortel's direction and pursuant to a valid invoice therefor, promptly pay to Nortel or pay directly to the applicable government or taxing authority, if requested by Nortel, taxes and charges which may be imposed by any federal, state, or local governmental or taxing authority arising hereunder, such as, but not limited to all such taxes and charges relating to the purchase, license, ownership, possession, use, operation and/or relocation of any Equipment, Software, or Services furnished by Nortel pursuant to this Agreement, excluding, however, all taxes computed upon the net income of Nortel. Nortel shall cooperate with the electronic delivery of Software if requested by Teligent. Teligent shall be obligated to pay associated penalties and interest only if such charges are imposed materially due to Teligent's negligent or deliberate failure to pay after being given adequate (at least thirty (30) days) notice of such tax liability. Buyer's obligations pursuant to this Section 6 shall survive any termination of this Agreement. Prices of imported equipment in the Core Deliverables, if any, are destination duty paid and applicable duties, if any, are included in the price. 7. RISK OF LOSS, TITLE AND DELIVERY 7.1 Risk of loss or damage and title to Core Deliverables (excluding Software) shall pass to Buyer upon delivery to the loading dock at the installation site or other delivery location specified by Buyer in its Order, and Buyer shall keep such Core Deliverables fully insured for the total amount then due Nortel for such Core Deliverables.

TAS equipment: [redacted] from acceptance of Order to delivery of complete units; or [redacted] from acceptance of Order to completion of installation, if so specified in the Order, and passage of the TAS ATPs. 8.2 Installation Reschedule 8.2.1 [redacted] 8.2.2 In the event Buyer fails to provide Nortel advance notice of its desire as set forth above, Nortel shall be entitled to warehouse such Core Deliverables and to invoice Buyer for all reasonable and directly associated costs incurred by Nortel for such warehousing associated with such rescheduling. 9. ACCEPTANCE TESTING, TURNOVER AND ACCEPTANCE 9.1 Acceptance Testing 9.1.1 The Parties shall mutually develop acceptance test procedures ("ATP") and pass/fail criteria for Core Deliverables installed by Nortel. Such ATP shall consist of separate test plans for each of the major network elements provided by Nortel hereunder and, with respect to a System, an additional acceptance test plan for the System as an integrated whole ("System ATP"). 9.1.2 [redacted] 9.1.3 [redacted] 9.1.4 [redacted] 9.1.5 If Nortel does not install the Core Deliverables furnished hereunder, Nortel shall, prior to delivery of such, perform factory acceptance tests in order to confirm that such Core Deliverables are in accordance with the applicable Specifications. Nortel shall include with the shipment of any such Core Deliverables a certified copy of the test results demonstrating passage of such factory tests where normally available. Unless Buyer notifies Nortel to the contrary within [redacted] of the delivery of such Core Deliverables, Buyer shall be deemed to have accepted such Core Deliverables based upon such tests and acceptance shall be deemed to have occurred upon the delivery of such Core Deliverables. 9.1.6 Merchandise equipment shall be deemed accepted upon delivery to the Buyer. Services which are purchased separately from a System shall be deemed to be accepted upon completion of such Services. 9.1.7 [redacted] 9.1.8 [redacted] 9.1.9 [redacted] 9.1.10 [redacted] 9.1.11 In the event Buyer notifies Nortel of non- acceptance of a Core Deliverable and Nortel personnel travels to Buyer's installation site to remedy such non-acceptance and determines that non-acceptance is due primarily to a deficiency of the nature described in Section 9.1.10, Nortel may invoice Buyer for investigation of the matter, including the standard labor rate for Nortel's personnel who travel to Buyer's installation site and reasonable travel and living expenses incurred by such personnel. 9.2 Nortel acknowledges that Buyer may from time to time install certain Adjunct Deliverables not purchased through Nortel, and connect such Adjunct Deliverables to Nortel's Core Deliverables through standardized interfaces. Therefore, the Parties hereby agree, that during such situations when Adjunct Deliverables are installed, by either Nortel or Buyer, at the time of acceptance testing, the System ATP shall verify the proper function of the relevant standardized interface; and where it is verified during such System ATP that such Adjunct Deliverables comply with the relevant interface specification, the attachment of such Adjunct Deliverables to Core Deliverables shall not diminish Nortel's warranty on the Core Deliverables. 9.3 [redacted] 9.3.1 [redacted] 9.3.2 [redacted] 9.4 Nortel agrees that the Core Deliverables, [redacted] shall comply with open interface standards TR-08 and TR- 303 and other relevant Bellcore standards for switch interfaces. 9.5 Nortel shall not ship Core Deliverables unless such Core Deliverables have passed Nortel's standard factory tests. Teligent shall have the right to inspect Nortel's manufacturing facility upon reasonable notice. Teligent shall also have the right to request from Nortel an annual quality audit. 10. LIMITED WARRANTIES AND REMEDIES 10.1 Nortel warrants that the Core Deliverables shall meet or exceed the performance Specifications in Attachment L, or if Attachment L is silent, in Nortel's current published specifications, for the lesser of [redacted] from Turnover or [redacted] from delivery ("Warranty Period") under normal use and service such equipment and will be free from defective material and faulty workmanship. The Warranty Period may be extended at Teligent's option for an additional [redacted] upon payment of a warranty extension fee. The foregoing warranty shall not apply to items normally consumed during operation of Core Deliverables such as, but not limited to, lamps and fuses. Any installation Service performed by Nortel will be free from defects in workmanship for a period [redacted] from the completion date of such Service. The performance by Nortel of any of its obligations described herein shall not extend the applicable Warranty Period. 10.2 Subject to Section 10.9, Nortel's obligation under the warranty set forth in Section 10.1 above shall be limited to the replacement or repair, at Nortel's option and expense, of the defective Core Deliverables, or correction of the defective installation Services. Replacement Core Deliverables may be new or reconditioned at Nortel's option, and shall be warranted for the balance of the Warranty Period of the original equipment, or for 90 days, whichever is longer. 10.3 If Core Deliverables are not free from defects in material or workmanship and/or fail to comply with the applicable Specifications during the Warranty Period, Nortel shall repair, replace or modify the Core Deliverables so that they do comply with the applicable Specifications within [redacted] following receipt of such defective Core Deliverables, or within [redacted] on an emergency basis, if requested expressly by Teligent as set forth in Section 18.3. Subject to the provisions of Section 10.9, Nortel's obligation under this Section 10.3 shall be limited to repair, modification or replacement of the defective Core Deliverables or correction of the defective installation Services. 10.4 Nortel warrants that any Software licensed by Nortel to Buyer under this Agreement shall function during the Warranty Period of the Equipment (but in any event not less than [redacted]) with respect to which such Software is furnished without any material, service- affecting nonconformance to the applicable Specifications, provided that Buyer shall have paid all Software support fees. If the Software fails to so function, Buyer's sole remedy and Nortel's sole obligation under this warranty is for Nortel to correct promptly such failure to ensure that the Equipment performs to Specifications, if the Specifications adequately address the service-affecting aspects of the failure, or, if the Specifications do not adequately address the service-affecting failure, Nortel shall correct promptly such failure to Teligent's reasonable satisfaction, through, at Nortel's option, the replacement or modification of the Software or such other actions as Nortel reasonably determines to be appropriate. Any continuing service-affecting Software failure that materially affects the performance of Core Deliverables shall be treated under Section 10.9, below. 10.5 Nortel's warranties in Section 10.4 above shall only apply to the portion of the Software actually developed by Nortel, its Affiliates or Teligent-Approved Radio Vendors. All other Software shall be provided by Nortel "AS IS".

Nortel shall identify any such Software and the extent to which such warranties are assigned prior to shipment. 10.6 Major Outage Warranty 10.6.1 [redacted] During the System Availability Warranty Period, Nortel warrants to Teligent that Major Outages, as defined in Section 10.6.2, not attributable to Teligent or a third party's error, resulting from failures of Nortel's Core Deliverables shall be limited to [redacted] cumulative during any calendar quarter. Scheduled outages for any given System shall not be counted against this limit, as long as: (a) a scheduled outage is of less than [redacted] duration, and (b) there are no more than [redacted] scheduled outages during a given calendar quarter. [redacted] Excluded from this System Availability Warranty are outages due to failure by personnel, not contracted or certified by Nortel, to properly maintain the Core Deliverables or to follow Nortel documents provided to Buyer; third-party events or equipment; and Force Majeure events. Such liquidated damages are to be paid in credits that may be applied against outstanding invoices and/or future Orders placed by Teligent under this Agreement. 10.6.2 For purposes of this Agreement, "Major Outages" shall mean (a) an unscheduled loss of engineered and installed call or data processing capacity (as measured by the most limiting capacity parameter) in excess of [redacted] or (b) or any unscheduled service-affecting failure in [redacted] or more of the Nodes (but at least [redacted] Nodes) at any one time (according to the system logs). 10.6.3 The System Availability Warranty shall apply only to Systems in which the Core Deliverables affected by the Major Outage are purchased according to the models shown in Attachment G, or if the Core Deliverables are of non-standard configurations or have been re-engineered for growth, if the standard recommended spares in connection therewith have been purchased and the engineered redundancy in the Core Deliverables is as recommended by Nortel, such engineered redundancy to be consistent with that reflected in the standard models. 10.6.4 In no event shall Nortel's liability for such penalties pursuant to this Section 10.6 exceed [redacted]. 10.7 Parameter Warranty [redacted] 10.8 Capacity Warranty 10.8.1 During the Term, Nortel warrants the capacity of the Core Deliverables as specified in Attachment L and its published Specifications. For Radio Products, capacity is limited to that specified in Section 10.7(d) minus necessary overhead (i.e., for [redacted] available bandwidth for payload (user data rate) is [redacted].

Additional equipment and costs directly attributable to this breach of this Warranty shall be negotiated by the Parties in good faith. 10.8.2 If Teligent chooses to license a new Software release, such upgrade may require changes to the capacity or purchases of additional Equipment. Each such Software release shall have a revised capacity warranty based on Teligent's new Equipment and Software configurations. The warranty of the capacity of the Core Deliverables shall be contingent upon Buyer having maintenance on such Core Deliverables adequately and properly performed. 10.9 During the Warranty Period, in the event Nortel is unable to repair or replace a defective Core Deliverable which is service affecting, and Nortel's inability to repair or replace such material and service affecting defective Core Deliverable exceeds a period of [redacted] then, at Buyer's election, Nortel shall remove such service affecting defective Core Deliverable, at Nortel's expense, and reimburse Buyer for any costs or expenses Buyer may incur as a result of the reinstallation of equivalent non-defective product or equipment as well as reimburse Buyer the full Order price of the defective Core Deliverable. Buyer shall submit to Nortel an invoice for such reinstallation costs or expenses and Nortel shall pay Buyer for such amounts. The obligations and remedies set forth herein shall be subject to the conditions set forth in Section 12. 10.10 The obligations and remedies set forth in this Section 10 shall be conditional upon: the Buyer having properly installed, repaired and maintained the Equipment using Nortel-qualified personnel; the Software not having been modified; no material failure of Buyer to comply with Buyer's Obligations, as set forth in the Statement of Work, any defect or nonconformance not being the result of mishandling, abuse, misuse, improper storage, maintenance or operation by other than Nortel (including use in conjunction with any product which is incompatible with the applicable Core Deliverables or of inferior performance, except as provided in Section 9.2), and/or any error, act, or omission of Buyer described in Section 12.5; the Core Deliverables not having been damaged by fire, explosion, power failure, power surge, or other power irregularity, lightning, failure to comply with all applicable environmental requirements for the Core Deliverables specified by Nortel or any other applicable supplier, such as but not limited to temperature or humidity ranges, or any act of God, nature or public enemy; and written notice of the defect having been given to Nortel within the applicable Warranty Period. 10.11 The performance by Nortel of any of its obligations in this Section shall not extend the applicable Warranty Period, except as specifically stated otherwise herein. 10.12 Unless Nortel elects to repair or replace defective Equipment at Buyer's facility, all Equipment to be repaired or replaced, whether in or out of warranty, shall be packed by Buyer in accordance with Nortel's instructions and shipped at Buyer's expense and risk of loss to a location designated by Nortel. Replacement Equipment shall be returned to Buyer at Nortel's expense and risk of loss. Buyer shall ship the defective Equipment to Nortel within thirty (30) days of receipt of the replacement Equipment. In the event Nortel fails to receive such defective Equipment within such thirty (30) day period, Nortel shall invoice Buyer for the replacement Equipment at the then-current price in effect therefor. 10.13 If the Core Deliverables returned to Nortel pursuant to the immediately preceding paragraph are determined by Nortel to be beyond repair or are outside the Warranty Period, Nortel shall notify Buyer and if requested Nortel shall sell Buyer replacement Core Deliverables at the then-current contract price between the Parties for such Core Deliverables or if no such contract exists, at Nortel's then-current price for such Core Deliverables. Such repair and replacement Service and notice of any discontinuance of such repair and replacement Service shall be available for a minimum period set forth in Section 18. This provision shall survive the expiration of this Agreement. 10.14 Buyer shall bear risk of loss and shall pay for all transportation charges for Core Deliverables returned to Nortel and Nortel shall bear such risk and pay for transportation charges for repaired or replacement Core Deliverables shipped to Buyer. 10.15 Subject to Section 2.1.3, with respect to any OEM Equipment furnished by Nortel to Buyer pursuant to this Agreement, Nortel shall assign to Buyer on a nonexclusive basis any warranty granted by the party that supplied such OEM Equipment to Nortel to the extent of Nortel's right to do so. 10.16 Neither Nortel nor Nortel's suppliers, as appropriate, shall have any responsibility for warranties offered by Buyer to any of its customers. Buyer shall indemnify Nortel and Nortel's suppliers, as appropriate, with respect thereto. 10.17 THE WARRANTIES AND REMEDIES SET FORTH IN THIS SECTION ----------------------------------------------------- CONSTITUTE THE ONLY WARRANTIES OF NORTEL WITH RESPECT TO -------------------------------------------------------- THE CORE DELIVERABLES AND SERVICES AND BUYER'S EXCLUSIVE -------------------------------------------------------- REMEDIES IN THE EVENT SUCH WARRANTIES ARE BREACHED. -------------------------------------------------- THEY ARE IN LIEU OF ALL OTHER WARRANTIES, WRITTEN OR ---------------------------------------------------- ORAL, STATUTORY, EXPRESS OR IMPLIED, INCLUDING, WITHOUT ------------------------------------------------------- LIMITATION ANY WARRANTY OF MERCHANTABILITY OR FITNESS ----------------------------------------------------- FOR A PARTICULAR PURPOSE.
