Support and Maintenance

Maintenance Support § § § Remote Maintenance, Monitoring and Support Note: This service requires that the mine has and maintains high speed data radios on all equipment to be monitored Technical Support Service: Email and phone access to Terralite XPS product support personnel to troubleshoot hardware and software related issues. Remote Access Service: Terralite XPS product support personnel can monitor customer systems remotely to assist customers with troubleshooting hardware and software issues Application support such as system configuration, installation and operational procedures

Software Maintenance § Software/Firmware Maintenance: Software/firmware service packs are available to update customer’s current major version of Terralite XPS products. Service packs include release notes and are provided as Ethernet and USB files. Service packs do not include upgrades to the next major version of the product which upgrades are offered and sold separately.

Data Review § § Log Files and Event Review: Review of data, including information on voltage, temperature, RTK, communication and XPS signal transmission, collected using Terralite constellation components. Note: This service requires that the mine has and maintains high speed data radios on all equipment to be monitored.

Constellation Review § Proactive Alignment of Constellation and Mine Plan: Trimble engineers will work with Customer to direct possible constellation changes to ensure proper coverage maximizing XPS signal utilization. Customer must supply a 3 -D short range (3 -6 month) mine plan in order to use this service. This service does not include labor or any on-site services; on-site service is available at then current daily service rate. Alignment and relocation service does not include moving the constellation to a new coverage area.

Quarterly Reports § Quarterly Status Reports: To include current constellation status, availability and any outstanding issues. These reports will outline the current status of the constellation including any equipment failures that may have happened. Key operational variables such as voltage, temperature, communications and availability will be included in this report.

On-Site Support § Quarterly Site Inspection/Service (three (3) days per visit maximum): On a scheduled quarterly basis, a Terralite XPS product support specialist will visit the site to inspect and/or service equipment covered under maintenance support. If any defects are found during the inspection, the support specialist will attempt to repair the defect. A purchase order may be required for parts or supplies used to accomplish the repair. The support specialist may deliver a quote for any items that need to be ordered and installed by the site. A report will be generated detailing what was found during the visit and inspection. If additional days over the allotted three (3) days per visit are required, they will be billed at then current daily service

Extended Hardware Warranty § § Site Spares: Trimble will stock the site with sufficient IX-100 and TX-100 units to ensure replacements for equipment covered by the Extended Hardware Warranty. The site is responsible for returning non-working equipment to Trimble via the RMA process in a prompt manner. Delays in returning equipment for repairs may affect the availability of site spares. Equipment Replacement for Products not Covered by the Extended Hardware Warranty: During the term of the maintenance support period, damaged hardware Products that are not covered under the Extended Hardware Warranty and are covered under the support agreement may be replaced by the Customer at the current list price for such Product less any site discount.

Response Times § § Response Times: All defects must be promptly communicated to Trimble’s account manager via e-mail. - Severity Level: Defects reported by Customer shall include a Severity Level designation as determined by Customer. If, within Trimble’s reasonable discretion, Customer’s Severity Level determination is inaccurate, said change shall be entered and Trimble shall notify Customer via e-mail. In the event that Trimble utilizes resources towards the response and/or resolution of a defect and it is later determined that said defect: (a) was not caused by the Products; or (b) is otherwise excluded from coverage under this Agreement; Trimble may charge Customer for all efforts and expenses incurred in responding and resolving said § Product defect, on a fee for service basis. § Severity Level designations consist of the five (5) classifications defined below:

Severity Levels

Response Times § Target Response Time and Target Resolution Time: Each Severity Level designation shall have an accompanying Target Response Time and Target Resolution Time as summarized in the tables below.
