 “AMENDMENT AGREEMENT NO. 1”

  
 This Amendment Agreement No. 1 to the FWA PLA, dated as of September 15,
2003 (the “Amendment Agreement No.1”), is entered into among Nortel Networks Limited (“NNL”), Nortel Networks de México, S.A. de C.V. (“NN Mexico” and, together with NNL,
“Nortel Networks”), and Axtel, S.A. de C.V. (the “Customer”). 
  
 WHEREAS, the parties entered into a Purchase and License Agreement for FWA equipment, dated as of March 20, 2003 (the “FWA PLA”), regarding the supply of telecommunications transmission
equipment and related services from Nortel Networks to the Customer; 
  
 WHEREAS, the Customer wants to increase the purchase volume of FWA Equipment (as defined in section 2.1.2 of Annex D of the FWA PLA) as set forth in this Amendment Agreement No. 1; 
  
 WHEREAS, the parties want to amend the FWA PLA exclusively in connection to the
incremental volume for the supply of FWA Equipment and the payment terms applicable to said incremental volume as set forth in this Amendment Agreement No. 1; 
  

NOW, THEREFORE, the parties hereto hereby agree as follows: 
  

	 	1.	The parties hereby agree that under the FWA PLA, the Customer may purchase additional FWA Equipment beyond the minimum purchase commitment established in Annex H of the FWA PLA; in
accordance with the foregoing, the Customer will purchase the FWA Equipment (the “Incremental FWA Equipment”) specified in Attachment A to this Amendment Agreement No.1 (hereinafter Attachment “A”) by placing
incremental Purchase Orders as scheduled in Attachment “A” (hereinafter the “Incremental Orders”). Pursuant the terms set forth in Section 18.4 of the FWA PLA, the Parties hereby agree that such Incremental
FWA Equipment will have special payment and delivery terms, which are set forth in the Attachment “A” of this Amendment Agreement No. 1, therefore, the Parties agree that all the terms and conditions of the FWA PLA shall apply to the
Incremental Orders except for those specific delivery and payment terms referenced in the Attachment A. 

 1.1. Incremental Orders for Incremental FWA Equipment shall only be placed and/or accepted within a given
year after all Purchase Orders for the Total Annual Minimum Commitment of the FWA PLA for that year have been placed. 
  
 1.2. All FWA Equipment Purchase Orders shall clearly state their reference to; a) Orders corresponding to Annex H Purchase Commitment of the FWA PLA, b)
Purchases within the original context of the FWA PLA or c) Orders corresponding to the specific conditions of this Amendment Agreement No. 1. 
  

	 	2.	The parties hereby agree that the payment terms specified in Attachment A will apply exclusively for the Incremental Orders specified in Attachment A; provided, however, that
the Customer: (a) complies with the Purchase Commitment established in Annex H; and (b) places the Incremental Orders according to the schedule specified in Attachment A. 

  

	 	3.	The parties hereby agree that if the Customer fails to place the Incremental Orders as described in Attachment A and/or fails to meet the payment schedule for the Incremental FWA
Equipment as described in Attachment A; this agreement will loose all force and effect fifteen (15) working days after written notification has been provided to the Customer by Nortel Networks, unless Customer cures such breach in the fifteen (15)
working days period; and: 

  

	 	(i)	all the original terms and conditions established in the FWA PLA for the purchase of FWA Equipment will apply. 

  

	 	(ii)	Nortel Networks will not reimburse the payment of the one-time capacity charge specified in section 7 below to the Customer. 

  

	 	(iii)	Nortel Networks will procure from the payments made by Customer to Nortel Networks for the Incremental FWA Equipment, all the proven and confirmed expenses and costs incurred as
well as a reasonable provision for all likely future expenses and costs to be incurred by Nortel Networks in its efforts to achieve the delivery profile in Attachment A (the “Special Expenses”), provided that such expenses
and costs incurred to date shall be proved by Nortel Networks to the 

  

 2 

 Customer by the production of a third party invoice and provided that a list explaining the provision
for future expenses and costs shall be provided by Nortel Networks. 
  

	 	(iv)	Nortel Networks shall, at its sole discretion, deliver to Customer the Incremental FWA Equipment paid and guaranteed by Customer, which can be manufactured by Nortel Networks after
taking the Special Expenses mentioned in section (iii) above or return the outstanding balance after taking the Special Expenses mentioned in section (iii), in such event, Nortel Networks shall return to Customer such outstanding balance in a period
no longer than 180 days after the cure period mentioned in this Section 3. 

  

	 	(v)	After the return of the outstanding balance mentioned in section iv), Nortel Networks will procure from the provision mentioned in section iii) all further proven and confirmed
expenses and costs incurred, provided that such expenses and costs incurred shall be proved by Nortel Networks to the Customer by the provision of a third party invoice. Nortel Networks shall return the outstanding balance of the provision mentioned
in section iii) in a period no longer than 365 days after the cure period mentioned in section 3. 

  

	 	4.	All Incremental Orders shall reference this Amendment Agreement No. 1 and shall comply with the Order Procedure specified in Annex E of the FWA PLA. All Incremental Orders are
totally binding and non-cancelable. 

  

	 	5.	Any change to the Incremental Orders shall be made pursuant the terms set forth in Section 2.7 of the FWA PLA. 

  

	 	6.	Nortel Networks shall make reasonable commercial efforts to deliver the Incremental FWA Equipment in accordance with the delivery schedule set forth in Attachment A of this
Amendment Agreement No.1. Delivery locations shall be as per Annex E of the FWA PLA. 

  

	 	7.	In exchange of Nortel Networks’ considerations set forth in Sections 8 and 9 below, and in order to facilitate the Incremental FWA Equipment delivery profile outlined in
Attachment A, the Customer shall pay Nortel Networks a one-time non-reimbursable capacity charge of six hundred thousand dollars of the United States of America (US$ 600,000) in three installments as per the payment schedule defined in Attachment A.
If after paying the first or first and second of the three installments the Customer fails to make the outstanding installment(s), the RSS delivery profile shall reduce to a volume of no more than 5,000 units per month from April 2004 and the
installment(s) already paid will be forfeited. 

  

 3 

	 	8.	Nortel Networks hereby waives the requirement specified in Annex H Section 1 f) for Customer to purchase 50,000 compact RSS brackets. 

  

	 	9.	Nortel Networks will make available to Customer at no charge approx. 4,000 RPCUs currently at a third party repair facility in Mexico. These units require an unknown level of repair
to return them to a usable state. Nortel Networks will make these units available “as is” with no warranty and accepts no liability for their current or future performance. Customer will be responsible for all repair costs associated with
returning these units to a functional state, disposal costs for units deemed unrecoverable, transportation costs associated with relocating these units to Customer’s premise and any storage charges incurred from September 15th 2003 until these
units are relocated to a Customer premise 

  

	 	10.	This Amendment Agreement applies solely to the Incremental Orders as defined in Attachment A and shall terminate on completion of the delivery of the Incremental FWA Equipment
ordered. This Amendment creates no precedent for any future agreements or amendments with respect to the supply of FWA Equipment or Service. 

  

	 	12.	Except as otherwise provided in this Amendment Agreement, the FWA PLA shall remain in full force and effect, including all terms and conditions in connection to the supply of FWA
Equipment. 

  

	 	13.	Capitalized terms used in this Amendment Agreement shall have the meaning ascribed to those terms in the FWA PLA. 

  
 IN WITNESS WHEREOF, this Amendment Agreement was signed as of the date first above
written.

 Technical Assistance Support Services Agreement for FWA Equipment 
  

	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
Federación on the date of payment; provided, however, that payment may only be made in Mexican pesos as long as the Services are being provided by a Mexican legal entity. 

  

	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
that Nortel Networks receives a net amount equal to the full amount which would have been received had the payment not been subject to such deduction or withholding. 

  

	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 

  

	3.1	Nortel Networks shall invoice Customer for the TAS Services every three (3) months, 30 days in advance of the invoice due date, for TAS Services to be provided within such 3-month
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. 

  

	3.4	All payments shall be made in accordance with the payment instructions contained in the applicable invoice if they are not in conflict with the provisions of this Agreement.

  

 Page 2 

 Technical Assistance Support Services Agreement for FWA Equipment 
  

	3.5	Customer shall pay interest on any late payments at the rate of 18% per annum (1 1⁄2% per month). 

  

	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
to the Services and designs, documentation and other work product prepared by Nortel Networks and delivered to Customer, (ii) all original works, computer programs and updates developed in the course of providing the Services (except Customer’s
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. 

  

 Page 5 

 Technical Assistance Support Services Agreement for FWA Equipment 
  

	10.2	IN NO EVENT SHALL NORTEL NETWORKS OR ITS AGENTS OR SUPPLIERS BE LIABLE FOR ANY OF THE FOLLOWING: A) DAMAGES BASED ON ANY THIRD PARTY CLAIM EXCEPT AS EXPRESSLY PROVIDED FOR HEREIN
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
POSSIBILITY. 

  

	11.	Force Majeure 

  

	11.1	Neither party shall be liable for delays or nonperformance of this Agreement occasioned by fire, casualty, explosion, lightning, accident, strike, lockout, labor unrest, labor
dispute (whether or not, in respect of the foregoing labor-related matters, the affected party is in a position to settle the matter), war (declared or undeclared), armed conflict, civil disturbance, riot, Act of God, delay of common carrier, the
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 

  

	13.1	Without prejudice to any rights and remedies provided for hereunder, either party hereto may terminate this Agreement, effective immediately, upon written notice to any other party,
upon the occurrence of any of the following events or conditions (each, an “Event of Default”): 

  

	 	(i)	the other party applies for or consents to the appointment of, or the taking of possession by a receiver, custodian, trustee or liquidator of itself or of all or a substantial part
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: 

  

	 	(i)	Customer fails to make payment in accordance with the terms and conditions hereof, which failure continues for a period of ten (10) business days (in Mexico) after written notice to
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  

  

	14.1	Confidential information (“Information”) means: (i) software; and (ii) all business, technical, marketing and financial information and data that is clearly marked with a
restrictive legend of the disclosing party (“Discloser”). 

  

	14.2	The party receiving Information (“Recipient”) will use the same care and discretion to avoid disclosure, publication or dissemination of Information as it uses with its
own similar information that it does not wish to disclose, publish or disseminate. The Recipient may disclose Information only to: (i) its employees and employees of its parent, subsidiary or affiliated companies or subcontractors who have a need to
know for purposes of carrying out this Agreement; and (ii) any other party with the Discloser’s prior written consent. Before disclosure to any of the above parties, the Recipient will have a written agreement with such party sufficient to
require that party to treat Information in accordance with this Agreement. 

  

	14.3	The Recipient may disclose Information to the extent required by law. However, the Recipient must give the Discloser prompt notice and make a reasonable effort to obtain a
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.	General Provisions 

  

	15.1	This Agreement will be governed by and construed in accordance with the laws of the State of New York, United States of America, with the exclusions of its conflicts of law
provisions. 

  

 Page 8

	 	•	Perform REM software upgrades 

  
 The terms and conditions for these services are set forth in this Exhibit B. 
  
 Here follows a description of the Services to be provided by Nortel Networks: 
  

	1.1	Technical Support Services 

  
 Technical Support Services, the foundation of the Nortel Networks Support Services portfolio, provides remote support for issues associated with the
operation and maintenance of Nortel Networks products. Technical Support Services includes two levels of service: 
  

	 	•	Remote Technical Assistance 

  

	 	•	Emergency Recovery 

  
 Remote Technical Assistance provides assistance to address network issues that are not classified as emergency priority. Nortel Networks will register and
manage requests for Technical Assistance during normal business days and business hours observed by Nortel Networks in the region where the service is being performed. 
  
 Note: Nortel Networks classifies Technical Assistance case priorities as Business Critical, Major, and
Minor. Please refer to “1.1.6 Technical Support Case Priority Classifications and Examples.” 
  
 Emergency Recovery provides assistance to address emergency network issues. Nortel Networks will register and manage requests for Emergency Recovery 24
hours per day, seven days per week including holidays observed by Nortel Networks in the region where the service is being performed. 
  

 Page 2 

 Note: Nortel Networks classifies Emergency Recovery case priorities as E1 and E2. Please
refer to “1.1.6 Technical Support Case Priority Classifications and Examples.” 
  
 To provide Remote Technical Assistance and Emergency Recovery, Nortel Networks technicians and engineers will provide support primarily by remote means. In a collaborative effort with Axtel’s technical staff,
these personnel will attempt to diagnose and resolve issues related to the hardware, software, and/or documentation supplied by Nortel Networks as explained in this service description. 
  
 For both Remote Technical Assistance and Emergency Recovery, where telephone support, remote diagnosis, and all other means
of restoring product operation have failed, Nortel Networks, upon Axtel’s request, and if Nortel Networks determines that on-site support is necessary and appropriate, will dispatch a trained and qualified technical expert to Axtel’s
premises to facilitate further diagnosis. 
  

	 	•	Notwithstanding Nortel Networks’ determination that on-site support is not necessary, Axtel will nevertheless have the right to require on site support from Nortel Networks,
provided that such on site support required by Axtel shall be at Axtel’s cost unless it is agreed that it was necessary for such support to be provided on site. 

  

	1.1.1	Technical Assistance Deliverables 

  
 Resolution activities, based on typical cases, may include: 
  

	 	•	Remote Troubleshooting problems using diagnostic utilities 

  

	 	•	Providing advice on how to detect and resolve hardware and network-related problems 

  

	 	•	Advising on issues requiring hardware replacement 

  

	 	•	Diagnosing issues related to Nortel Networks products interfacing with non-Nortel Networks products 

  
 Note: Nortel Networks will resolve the issue to the point of demonstrating that the problem is
attributable to the non-Nortel Networks products and, under the coordination of Axtel, a Nortel Networks technician can be available to discuss the fault issue with the appropriate vendor.  
  

	 	•	Analyzing trace/log/dump/Operational Measurement (OM) information 

  

	 	•	Remote telephone and/or email support to Nortel Second Level support (NTS) in troubleshooting, diagnosing and correcting failures by Nortel Networks hardware and/or software to
function as per the relevant Nortel Networks product specifications in Axtel’s network. Providing regular, on-going updates on case progress using an agreed-upon medium 

  

	 	•	Service Restoration and Resolution of the reported cases in accordance with Section 2.2.3 below of this Exhibit. 

  

 Page 3 

	1.1.2	Emergency Recovery Deliverables 

  
 Nortel Networks Emergency Recovery teams respond to customer emergencies 24 hours a day, 365 days a year. Customer emergencies are cases that are
classified as E1 or E2 in accordance with Nortel Networks Case Priority Classification. 
  
 Note: Please refer to “1.1.6 Technical Support Case Priority Classifications and Examples.” 
  
 Nortel Networks strives to immediately assign an engineer upon receipt of the call. Thereupon, Nortel Networks will provide
continuous support as applicable until the service level is restored to pre-incident operation. The Emergency Recovery team will be in constant contact with Axtel throughout this case resolution activity, if requested. 
  
 Note: Please refer to “2.2 Call
Center Access for Technical Support.” 
  
 Following
service restoration, the E1/E2 case will be closed in agreement with Axtel and a follow-up case (Major for E1 and Minor for E2) can be opened, if further investigation or problem resolution activity is needed. Furthermore, Nortel Networks may, where
applicable, conduct a root-cause analysis of the emergency incident, which may be made available to Axtel. 
  

	1.1.3	Axtel Responsibilities for Technical Support Services 

  
 For both Technical Assistance and Emergency Recovery Axtel will be required to: 
  

	 	•	Confirm that the products are installed, commissioned, used and maintained by knowledgeable and skilled people acting in accordance with the applicable product documentation from

diagnosis and maintenance 

  

 Page 4 

 Note: Axtel and Nortel Networks technical personnel will agree on the appropriate type
of data link based on network equipment and configuration as well as the appropriate security measures to prevent unauthorized access. Axtel will be solely responsible for security of the network. Nortel Networks will not connect to Axtel’s
network without prior authorization and such connection will be solely to provide technical support. 
  

	 	•	Excuse Nortel Networks from fault resolution for a period equal to such failure or delay, should Axtel fail or cause delay in providing connectivity 

  

	 	•	Designate and make available competent personnel to aid in problem diagnosis and provide electronic access to the affected product(s) to aid in problem investigation and resolution
for all incidents. For E1/E2 Axtel personnel should be available to work together with Nortel Networks technical expert throughout the process. 

  

	 	•	Axtel should provide their internal escalation process in order to inform all the contacts to Nortel Networks.

	 	•	Axtel’s in-house structure that performs first-line support will need to exhaust internal troubleshooting processes. First-level Operations, Administration, and Maintenance
(OA&M) functions may include, but are not limited to:  

  

	 	•	Performing day-to-day maintenance and network operations 

  

	 	•	Monitoring network and system alarms 

  

	 	•	Performing diagnosis in accordance with instructions provided by Nortel Networks and carrying out initial remedial actions, including remote diagnosis 

  

	 	•	Operating and controlling Axtel’s internal help desk for logging and tracking fault inquiries, prioritizing events, and escalating, as required, to the Nortel Networks
technical support group 

  

	 	•	Providing local time templates and historical actions performed on each event as reference information to the Nortel Networks technical support group (NTS).

Engineer is waiting on a Customer response in order to continue investigation	  	Stopped

  

					
	 Status

	  	 Description

	  	 Nortel Clock

	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
			
	 Solution
 Delivered
	  	Solution Delivered or available for testing and verification. If the delivered solution does not resolve the reported problem, the status will be changed to Work in Progress (Level 1 or 2).

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.
