	2.	Price 

  

	2.1	The price for the Services to be rendered by Nortel and for the provision of the Software Enhancement Release and related services are indicated in Exhibit A. All amounts have been
expressed in US Dollars and do not include any taxes that may be levied by any governmental authority for the sale of the Services. 

  

	2.2	If any payment hereunder is to be made in Mexican pesos, the prices in Exhibit A shall be converted to Mexican pesos at the exchange rate published in the Diario Oficial de la

	2.3	Each party shall be responsible for the payment of its own income taxes as they relate to this Agreement. If any authority imposes a tax, duty, levy or fee, excluding those based on
Nortel Networks’ net income, in connection with the Services supplied by Nortel Networks under this Agreement, Customer agrees to pay that amount as specified in the invoice, or provide exemption documentation. 

  

	2.4	If Customer is compelled by law to deduct or withhold any amounts from any payment, then Customer shall pay to Nortel Networks such additional amounts as may be necessary to ensure

	2.5	Customer consents without qualification to the sale of receivables by Nortel Networks, subject to a 30-day prior written notice, and authorizes the disclosure of this Agreement and
any attachments or associated documents as necessary to facilitate such sale. Any tax impact to Customer resulting from such sale and/or assignment shall be borne by Nortel Networks. 

  

	3.	Payment Terms

period. 

  

	3.2	Nortel Networks shall invoice Customer one hundred percent (100%) of the price of Other Services upon completion, unless the Other Service continues beyond thirty days, in which
case Nortel Networks shall invoice Customer at the end of each month for the Other Services performed in that month. 

  

	3.3	Payment for the Services rendered by Nortel Networks shall be within thirty (30) days from the date of invoice is received by Customer.

	4.	Term 

  

	4.1	The term (“Term”) of this Agreement shall start on the Closing Date (as such term is defined in the Restructuring Agreement) and shall continue for the same term as the
Purchase and License Agreement for FWA Equipment of even date herewith, entered into among Nortel Networks Limited, Nortel Networks de Mexico, S.A. de C.V. and Customer (the “FWA Supply Contract”). 


 

	5.	Customer Responsibilities  

  

	5.1	Customer agrees to reasonably cooperate with Nortel Networks in the performance by Nortel Networks of the Services, including, without limitation, providing Nortel Networks with
sufficient and timely access free of charge to facilities, data, information and personnel of Customer in accordance with Customer’s then-current access internal policies, including the recovery by Nortel Networks of any diagnostic or test
equipment, documentation or other items used by Nortel Networks in the performance of the Services. 

  

	5.2	In addition, Customer shall be responsible for the accuracy and completeness of all data and information that it provides or causes to be provided to Nortel Networks. In the event
that there are any delays by Customer in fulfilling its responsibilities as stated above, there is a disagreement between the parties as to the cooperation required from Customer, or there are errors or inaccuracies in the information provided,
Nortel Networks shall be entitled to appropriate schedule and pricing adjustments. 

  

	6.	Personnel 

  

	6.1	Nortel Networks and Customer are each responsible for the supervision, direction, compensation and control of their own employees and subcontractors. Nortel Networks may subcontract
any portion or all of the Services to subcontractors selected by Nortel Networks. 

  

	6.2	Neither party shall knowingly hire, engage as independent contractors or solicit employees of the other party with whom it had contact as a result of the performance of the Services
for a period ending one year after completion of the Services. Neither party shall be precluded from conducting generalized searches for employees (and hiring those employees who respond to generalized searches), through the use of advertisements in
the media or through the use of search firms, provided that searches are not specifically targeted on employees providing Services.

	7.	Patents and Copyrights 

  

	7.1	Nortel shall indemnify and hold harmless Customer, its officers, directors, representatives, agents, employees, contractors, subcontractors, subsidiaries and affiliates against any
actual direct loss, damage, liability, cost, expense, action or claim, including reasonable attorneys’ fees, litigation costs and expenses and amounts paid in settlement, subject to the limitations set forth in the following paragraphs, arising
out of or in connection with any infringement or alleged infringement of patents, copyrights, trademarks, trade secrets, or any other intellectual property right of a third party. Therefore, if a third party claims that any materials manufactured by
Nortel Networks and provided to Customer in the performance of the Services infringe that party’s patent or copyright, Nortel Networks will defend Customer against that claim at Nortel Networks’ expense and pay all costs and damages that a
court finally awards or are agreed to in settlement, provided that Customer (a) promptly notifies Nortel Networks in writing of the claim; and (b) allows Nortel Networks to control, and cooperates with Nortel Networks at Nortel Networks’
expense in, the defense and any related settlement negotiations. If such a claim is made or appears likely to be made, Nortel Networks agrees to secure the right for Customer to continue to use the materials, or to modify them, or to replace them
with materials that are functionally equivalent. If Nortel Networks determines that none of these alternatives is reasonably available, Customer agrees to return the materials upon Nortel Networks’ written request. Nortel Networks will give
Customer a credit equal to the amount paid by Customer to Nortel Networks for the infringing materials returned. Any such claims against the Customer or liability for infringement arising from use of the materials following a request for return by
Nortel Networks are the sole responsibility of Customer. This represents Customer’s sole and exclusive remedy regarding any claim of infringement. 

  

	7.2	Nortel Networks has no obligation regarding any claim based on any of the following: (a) anything Customer provides which is incorporated into the materials; (b) compliance by
Nortel Networks with the Customer’s specifications, designs or instructions; (c) the amount of revenues or profits earned or other value obtained by the use of a product by Customer; (d) Customer’s modification of the materials or
products, provided that Customer is hereby authorized to generate new Software Scripts or modify the existing ones; provided, however, that Nortel Networks shall not be obligated to support such modified Software Scripts; and provided,
further, that Nortel Networks shall not be responsible for any performance issues resulting from such modified Software Scripts; or (e) Customer’s failure to install or have installed changes, revisions or updates as instructed by Nortel
Networks. 

  

	7.3	In case of any infringement caused by any Third Party Vendor Item, Nortel Networks shall reasonably cooperate with Customer and hereby assigns to Customer any of its rights to
request the proper defense and indemnification for such claim to such Third Party Vendor. Nortel Networks shall provide Customer with all necessary contact information and applicable documentation, if available, for those third party vendors.
Furthermore, Nortel Networks shall use its best efforts to provide reasonable assistance to Customer for Customer to be able to obtain from the Third Party Vendor the applicable defense and indemnification for such Third Party Vendor Item
infringement, but only to the extent such assistance does not cause Nortel Networks to incur any out-of-pocket expenses or material additional costs.

	8.	Intellectual Property 

  

	8.1	Nortel Networks, on behalf of itself and its subcontractors, reserves all proprietary rights in and to (i) all methodologies, designs, engineering details, and other data pertaining

developed programs) or as otherwise agreed in writing between the parties, (iii) discoveries, inventions, patents, know-how and techniques arising out of the Services, and (iv) any and all products (including software and equipment) developed as a
result of the Services. The performance by Nortel Networks of Services shall not be deemed work for hire. Nortel Networks grants to Customer a perpetual, non-exclusive, world-wide, paid up license to use, copy and modify the designs, documentation
and other work product prepared by Nortel Networks and delivered to Customer in the performance of Services solely for Customer’s internal business purposes. 

  

	8.2	It is understood between the parties that Nortel Networks will employ its know-how, techniques, concepts, experience and expertise, as well as all other intellectual property to
which it reserves its rights, to perform services the same as or similar to the Services for others. 

  

	9.	Warranty and Disclaimer 

  

	9.1	Nortel Networks will perform the Services in a professional and workmanlike manner. Customer shall notify Nortel Networks in writing of any non-conformance within sixty (60) days of
the date on which the Services are completed. Provided Customer gives written notice to Nortel Networks of any non-conforming Services within the above 60-day period, Nortel Networks will re-perform the non-conforming Services.


  

	9.2	THIS WARRANTY IS CUSTOMER’S EXCLUSIVE WARRANTY. NORTEL NETWORKS HEREBY DISCLAIMS ALL OTHER WARRANTIES AND CONDITIONS, EXPRESS OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
IMPLIED WARRANTIES AND/OR CONDITIONS OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. 

  

	10.	Limitation on Liability  

  

	10.1	In no event shall Nortel Networks or its agents or subcontractors be liable to Customer for more than the greater of the amount of any actual direct damages or the fees paid for
Services that are the subject of the claim, regardless of the cause and whether arising in contract, tort (including negligence) or otherwise. This limitation will not apply to claims for damages for bodily injury (including death) and damage to
real property and tangible personal property for which Nortel Networks is legally liable and payments as set forth in Section 7 - Patents and Copyrights.

AND IN SECTION 7; B) LOSS OF, OR DAMAGE TO, CUSTOMER’S RECORDS, FILES OR DATA; OR C) INDIRECT, SPECIAL, INCIDENTAL, PUNITIVE, OR CONSEQUENTIAL DAMAGES (INCLUDING LOST PROFITS OR LOST SAVINGS), EVEN IF NORTEL NETWORKS IS INFORMED OF THEIR

enactment, issuance, or application of any law, local by-law, regulation, or executive, administrative, or judicial order, acts (including delay or failure to act) of any governmental authority, or any other cause or causes (whether of the
foregoing, nature or not), or any other similar or different occurrence, which cause or occurrence is beyond the reasonable control of the affected party and whether or not foreseeable by such party (“Force Majeure”). However, if the delay
or non-performance due to Force Majeure exceeds 3 (three) months, the party not affected by Force Majeure may terminate this Agreement provided written notice has been given to the other party. 

  

	12.	Independent Contractors 

  

	12.1	The parties herein are independent contracting entities. Nothing herein shall be construed to create a relationship of employer and employee, joint venture, partnership or
association between Customer and Nortel Networks. Except as expressly provided herein, neither party shall have the right to bind or obligate the other party in any manner without the written consent of the other party. 

  

	13.	Termination; Survival

of its property, 

  

 Page 6 









 Technical Assistance Support Services Agreement for FWA Equipment 
  


	 	(ii)	the other party makes a general assignment for the benefit of its creditors, 

  

	 	(iii)	the other party commences a voluntary proceeding under the bankruptcy, insolvency or similar laws relating to relief from creditors generally, 

  

	 	(iv)	the other party fails to contest in a timely or appropriate manner, or acquiesces in writing to, any petition filed against it in an involuntary proceeding under the bankruptcy,
insolvency or similar laws relating to relief from creditors generally, or any application for the appointment of a receiver, custodian, trustee, or liquidator of itself or of all or a substantial part of its property or its liquidation,
reorganization, dissolution or winding-up; or 

  

	 	(v)	the other party materially fails to perform any term or condition under this Agreement or any of its Annexes, which failure continues for a period of thirty (30) days after written
notice has been given to the breaching party; provided, however, that if any party exercises its termination rights as provided in this Section 13.1 after the sale of the FWA Business by any affiliate of Nortel Networks, the FWA Supply
Contract shall automatically be terminated concurrently therewith; and provided, further, that if any party exercises its termination rights as provided in this Section 13.1 prior to the sale of the FWA Business by any affiliate of Nortel
Networks, the three other Replacement Agreements shall automatically be terminated concurrently therewith. 

  

	13.2	In addition, without prejudice to any other rights and remedies provided for hereunder, Nortel Networks may terminate all four Replacement Agreements, effective immediately, upon
written notice to Customer, upon the occurrence of any of the following events or conditions:

Customer, 

  

	 	(ii)	within eighteen (18) months from the date hereof, the identity of Customer’s business materially changes by sale of its business, transfer of control of its capital stock,
merger or otherwise, unless prior written consent therefore has been received from Nortel Networks; or 

  

	 	(iii)	the occurrence of an Event of Default under any one of the Senior Note or the other Replacement Agreements which by the terms of such agreements would allow Nortel Networks to
declare such Senior Note due and payable or to terminate such Replacement Agreement, as the case may be. 

  

	13.3	The respective obligations of each party pursuant to Sections 2, 3, 6, 7, 8, 9, 10, 12, 13, 14 and 15 hereof, and any other obligations of each party pursuant to this Agreement that
by their nature would continue beyond the termination, cancellation, or expiration hereof shall survive such termination, cancellation, or expiration; provided, however, that if 

  

 Page 7 









 Technical Assistance Support Services Agreement for FWA Equipment 
  

 Customer fails to make payment in accordance with the terms and conditions hereof (subject to the
cure period provided in Section 13.2 above), the parties expressly agree that Section 9.1 hereof shall not survive such termination, cancellation, or expiration. 
  

	14.	Confidential Information

restrictive legend of the disclosing party (“Discloser”).

protective order. 

  

	14.4	No obligation of confidentiality applies to any Information that the Recipient: (i) already possesses without obligation of confidentiality; (ii) develops independently; or (iii)
rightfully receives without obligations of confidentiality from a third party. No obligation of confidentiality applies to any Information that is, or becomes, publicly available without breach of this Agreement. 

  

	14.5	Each party’s obligations hereunder shall survive for a period of five (5) years after receipt of Information hereunder from the Discloser, except as otherwise mutually agreed
upon by the parties. 

  

	14.6	THE DISCLOSER MAKES NO REPRESENTATIONS OR WARRANTIES OF ANY NATURE WHATSOEVER WITH RESPECT TO ANY INFORMATION FURNISHED TO THE RECIPIENT, INCLUDING, WITHOUT LIMITATION, ANY
WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE OR AGAINST INFRINGEMENT.

	15.2	If, within thirty (30) days from the date of any notice of dispute from a Party to any other Party, such Parties are unable to resolve the issue, then either Party may initiate the
binding arbitration to resolve such dispute by written notice to such other Party upon expiration of such thirty (30) day period. Any dispute between the Parties arising in connection with this Agreement shall be exclusively resolved by arbitration
pursuant to the Rules of Conciliation and Arbitration of the International Chamber of Commerce then in force. The arbitration proceedings pursuant to this Section 18(c) shall take place in the English language in the City of Miami, State of
Florida, before a panel of three (3) arbitrators appointed in accordance with the aforementioned rules. The decision of the arbitrators shall be final and binding upon the Parties and their respective successors and assigns. The decision and award

	15.3	EACH PARTY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF, OR RELATING TO, THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREIN,
INCLUDING ANY ORDER ISSUED AND ACCEPTED HEREUNDER.

this Agreement. 

  

	15.5	If any of the provisions of this Agreement are found to be invalid under an applicable statute or rule of law, they are to be enforced to the maximum extent permitted by law and
beyond such extent are to be deemed omitted from this Agreement, without affecting the validity of any other provision of this Agreement. 

  

	15.6	The headings and captions in this Agreement are for convenience only and shall not be used to construe the meaning of this Agreement. 

  

	15.7	Customer agrees not to assign or otherwise transfer this Agreement or Customer’s rights under it, or delegate Customer’s obligations, without Nortel Networks’ prior
written consent, and any attempt to do so is void. Notwithstanding the foregoing, Nortel Networks may assign or otherwise transfer this Agreement or its rights under it, or delegate its obligations, to any of its affiliates or to any purchaser of
the FWA Business, under the terms set forth in Section 20 of the FWA Supply Contract.

	 Interim Solution
	 	If a temporary solution is provided that eliminates the customers pain until a permanent solution can be delivered, RQMS requirements allow the case to be set to an “IS” status during
this window of time if approved by the Customer. In calculating case age, this interval will be discounted if the permanent fix was delivered on the negotiated commitment date. If the permanent fix does not resolve the reported problem, case status
shall be changed to Work in Progress (Level 1 or 2). If the case is returned to a Work in Progress (Level 1 or 2) status after using the IS, the IS time period will be added to the RQMS age of the case.	 	Stopped
			
	 Future Deliverable
	 	Customer agrees to live with the problem condition and that the fix will be delivered as part of a future Nortel product release (software release, maintenance release, documentation release or
hardware revision. Requirements to use this status include Customer consent; fix identification, and delivery commitment. This status code does not add time to the RQMS age of the case unless the solution fails and the case is moved back to Work in
Progress (Level 1 or 2) status. If the case is returned to a Work in Progress (Level 1 or 2) status after using the FD, the FD time period will be added to the RQMS age of the case.	 	Stopped

 Exhibit D 
  

FIRST MARKET APPLICATION PROCESS 
  
 FOR ANNUAL FWA SOFTWARE RELEASE 
  

	1.0	Scope. 

  
 Nortel Networks will provide an annual product software release designed to enhance the functionality of the product. The content of the 2003 release
shall be agreed by both parties by contract start date. The content of subsequent years’ releases shall be agreed via bi-monthly Product Enhancement Conferences and by the end of September of the previous year. In the event that the annual
software release requires a software upgrade to the REM, this activity will be carried out by Nortel Networks. This document outlines the process by which the annual software releases and, if applicable, any associated REM upgrade will be made
available to AXtel. 
  

	2.0	Definition of First Market Application. 

  
 Each annual software release will be fully tested and verified by Nortel Networks at its facilities before being made available to AXtel for deployment in
their network. Such testing will be within the constraints of the Nortel Networks FWA R&D captive office environment i.e. testing will be in a simulated “live air” environment which emulates the Customer network in so far as this is
practical. Each release will be accompanied by a “Release Content Description” which will detail the contents of the release, system line up such as switch configuration & software version and if applicable, any limitations. If deemed
necessary by AXtel, Nortel Networks will assist AXtel in verifying the functionality of the annual software release within AXtel’s own FWA network. This activity will be termed “First Market Application”. 
  

	3.0	Responsibilities for First Market Application. 

  
 The primary objective of the First Market Application is to ensure functionality of the annual software release in the AXtel network and as such,
responsibility for the completion of this activity rests wholly with AXtel. Not withstanding the foregoing, Nortel Networks will work in support of AXtel in the First Market Application process. Note, all interaction and communication between Nortel
Networks and AXtel with respect to the First Market Application process will be in English. 
  

	 	3.1	AXtel Responsibilities in the First Market Application Process.
