Pricing for Additional Equipment -------------------------------- In the event that Tricom desires to purchase additional equipment for the CDMA Cellular System, Motorola agrees to provide Tricom with an additional twenty-five percent (25%) discount on the RF equipment in addition to the current discount level for the analog RF equipment which Motorola gives to Tricom's partner, Motorola Network Management Group. 3.5. Future Prices ------------- For a period of five (5) years after the Parties sign this CDMA Amendment, Motorola agrees to extend to Tricom the same prices as specified in Attachment A for Tricom's volume purchases of additional equipment in increments of a minimum of fifty thousand (50,000) lines, based on the same design criteria as the CDMA Cellular System. 4. TECHNICAL SPECIFICATIONS AND PROJECT REQUIREMENTS 4.1. The Parties agree to add the CDMA technical specifications attached hereto and incorporated herein as Attachment B1. 4.2. Motorola agrees to comply with tile following requirements in addition to adhering to the technical specifications in Attachment B1: 4.2.1 Motorola acknowledges that Tricom may use the services of an independent third party to assist Tricom with the CDMA Cellular System including such responsibilities as review and analyze the system design for the Initial CDMA Cellular System and the CDMA Expansion Product. 4.2.2 Motorola warrants the system design, coverage, capacity and call quality of the CDMA Cellular System. This Motorola warranty is based on the CDMA Cellular System capacity verification Utilizing Motorola's propagation tool in conjunction with another independent tool to audit the capacity of the Initial CDMA Cellular System and the CDMA Expansion Product and mutually agreed metric drive tests on the cell site cloisters which Motorola agrees to perform prior to Conditional Acceptance of that cluster. In the event that the Parties determine that the mutually agreed criteria have not been met, Motorola will first attempt to meet such criteria through reviewing the installation and optimization of the CDMA Cellular System. If, after Motorola reviews the installation and optimization of the CDMA Cellular System, the Parties determine that the criteria are still not met, then Motorola agrees to engineer a solution to meet the criteria and provide Motorola-manufactured Fixed Network Equipment, at its own expense, for that solution. 4.2.3 System Reliability Outage Credits. --------------------------------- Motorola agrees to provide Tricomwith an equipment purchase credit of (i) US $40,000.00 (forty thousand US dollars) for any unplanned system outage for a duration of more than sixty (60) minutes and (11) $500.00 (five hundred US dollars) for each additional minute after said sixty (60) minutes. Such outage must (i) render the entire CDMA Cellular System inoperative or make the completion of all outgoing or ingoing calls impossible and (ii) be due solely to the fault of Motorola-supplied equipment or Motorola personnel. The total amount of Motorola's credits shall not exceed US $1,000,000.00 (one million US dollars). At the time when Tricom issues the next valid purchase order for CDMA Expansion Product, Motorola shall apply these credits, at its option, to either future purchases of Motorola equipment or Tricom's open receivables. 4.2.3 Motorola agrees to provide Tricom with the following: (i) an Implementation Development Plan ("IDP") which shall include a list of the personnel assigned to this project, the services which Motorola shall provide, specific locations for the Sites, demarcation of each Party's respective responsibilities, etc., (ii) a progress report on a monthly basis indicating the status of the project, (iii) a list of recommended spare parts which Tricom may purchase at its option; such list is set forth in Attachment A1. The information regarding expanding the major system components (i.e., EMX 5000, CBSCS, and the BTS 4852) is set forth in the Attachment B1 Technical Specifications. 5.
