Such meeting shall be attended by individuals with decision-making authority to attempt, in good faith, to negotiate a resolution of the dispute prior to pursuing other available remedies. If, within fourteen (14) days after such meeting, the parties have not succeeded in negotiating a resolution of the dispute, then either party may commence arbitration under Subsection 7.3.2, below, by delivering a written demand for arbitration to the other party. MASTER PURCHASE AND LICENSE AGREEMENT PAGE 9 * CONFIDENTIAL MATERIAL OMITTED - FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION 7.3.2 If either party commences arbitration in the manner described above, the dispute will be subjected to binding arbitration before a panel of three (3) independent arbitrators.

The parties agree that the System shall be deemed accepted for purposes of this Agreement if the arbitrators conclude that the System is materially performing in accordance with the applicable Acceptance Test Plan. A judgment upon the award rendered by the arbitrators may be entered in any court having jurisdiction thereof and shall constitute a final adjudication of all matters submitted to arbitration. The arbitrators shall, as part of their written decision, award attorneys' fees and related expenses in accordance with Subsection 16.11, below. The costs of all arbitration services, however, shall be shared equally by the parties. 7.4 APPLICATION TO SUBSEQUENT INSTALLATIONS.

[*] Market Areas Licensee Name - ------------ ------------- [* * * * * * * * * *] MASTER PURCHASE AND LICENSE AGREEMENT PAGE 27 * CONFIDENTIAL MATERIAL OMITTED - FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION SCHEDULE D TO MASTER PURCHASE AND LICENSE AGREEMENT SPECIFICATIONS This Schedule contains the functional Specifications for a System as required by the Master Purchase and License Agreement between CTS and Customer (the "Agreement"). All undefined capitalized terms used in this Schedule shall have the meanings ascribed to such terms as set forth in the Agreement. Each overall System is comprised of one or more Regional Processor Systems and Cell Site Systems. BLACKBIRD-Registered Trademark- PLATFORM AND PRETECT-TM- APPLICATION FUNCTIONAL OVERVIEW Together, the Blackbird-Registered Trademark- Platform and PreTect-TM- form a home market cloning prevention solution, in which the Blackbird-Registered Trademark- Platform collects cellular phone data that PreTect-TM- measures and uses to interdict analog cellular phone cloning attempts in real time. BLACKBIRD-Registered Trademark- PLATFORM OVERVIEW The Blackbird-Registered Trademark- Platform is the data collection and storage platform for CTS's real time cellular fraud prevention applications. Using hardware and software at the Cell Site System (CSS) and Regional Processor (RP), the Blackbird-Registered Trademark- Platform collects and stores the following cellular call data that form a cellular call event signature, or "fingerprint": - Radio frequency (RF) transmission characteristics: The subtle differences between different cellular phones' RF signatures. - Mobile Identification Number (MIN): The unique phone number assigned a cellular phone. - Electronic Serial Number (ESN): The unique number programmed into a cellular phone during the manufacturing process. - [*] CTS designed the Blackbird-Registered Trademark- Platform as a platform for delivery of a modular system of cellular fraud prevention applications. The Blackbird-Registered Trademark- Platform Application Programming Interface (API) facilitates seamless integration of current and future CTS products to meet the changing fraud prevention requirements of its customers. PRETECT-TM- OVERVIEW PreTect-TM- is the real time cloning detection and interdiction application designed to function on the Blackbird-Registered Trademark- Platform. PreTect-TM- works to prevent cloning fraud. Over time, PreTect-TM- uses the information collected and stored by the Blackbird-Registered Trademark- Platform to build a unique fingerprint for each analog cellular phone. PreTect-TM- also measures each call attempt transmitted to a cell site against this fingerprint. This real time measurement process allows PreTect-TM- to quickly determine whether the attempt originated from a cloned analog cellular phone. MASTER PURCHASE AND LICENSE AGREEMENT PAGE 28 * CONFIDENTIAL MATERIAL OMITTED - FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION Users access PreTect-TM- through a Graphical User Interface on Hewlett Packard X-terminals or IBM PC-compatible computers running X-terminal emulation software. Through the graphical user interface, users can [*] Through the graphical user interface, users can configure PreTect-TM- to meet the needs of daily operations on their cellular network: - [*] Finally, [*]. This allows customer service and fraud prevention departments to better utilize the data storage and analysis capabilities of the Blackbird-Registered Trademark- Platform/PreTect-TM- system: - [*] SYSTEM HARDWARE OVERVIEW The Blackbird-Registered Trademark- Platform/PreTect-TM- system includes the following hardware systems: The Regional Processor(s) complex consists of one or more Regional Processors, routers and other hardware necessary to store cellular call data and maintain connectivity between the Cell Site System and regional processor system. - Regional Processor: Typically a Hewlett Packard 9000 series processor running the HP-UX operating system. - Router: Typically a CISCO 7000 series router used to provide TCP/IP Ethernet connectivity between the regional processor and each cell site. The Blackbird-Registered Trademark- Platform and PreTect-TM- software work with the regional processor system to provide real-time call data collection, storage and reporting. In addition, the Blackbird-Registered Trademark- Platform's distributed real-time message processing allows distribution of fingerprint data among multiple regional processor systems in large markets. The Cell Site System (CSS) consists of the cell site processor, radios and other equipment necessary to collect cellular call data, communicate with the regional processor system and shut down, or interdict, cloning attempts. One CSS is required for each cell site that uses the Blackbird-Registered Trademark- Platform/PreTect-TM- system. - Cell Site Processor (CSP): An industry-standard PC housed in an industrial-grade metal enclosure, with a cellular modem for remote network troubleshooting. - Radio: Cellular radios which collect cellular call data directly from the cell site antenna and transmit that data to the CSP without interrupting cell site call traffic. - Interdiction module: Hardware unit that performs interdiction of cloning attempts upon command from the CSP. The interdiction module will vary depending on the carrier's infrastructure type. Blackbird-Registered Trademark- and PreTect-TM- software work with the CSS to gather home market cellular call characteristics, relay information regarding those characteristics to the regional processor when necessary, and perform interdiction of cloning attempts.
