You are hereby directed to make the following additions or modifications to, or deductions from, the Work

Contractor is to immediately cease all design efforts associated with the supply of the proposed Notifier based fire panel system for use within the terminal process areas and begin the necessary activities to implement a Det-Tronics Eagle Premier Fire and Gas Detection System, as well as Det-Tronics Triple IR Point Gas, Open Path Gas and IR Flame Detectors for the monitoring of all terminal process areas.

The proposed Notifier NFS fire panel has been deemed acceptable by SPLNG for monitoring of the Administration, Warehouse and Control Buildings.

The necessary hardwired cross connections shall be provided to integrate the Det-Tronics and Notifier systems. A Det-Tronics S3 console shall act as the central annunciating console for the combined building and process area fire and gas detection system. A serial interface shall also be provided between the Notifier NFS and the Det-Tronics systems to allow for Notifier data to be passed to, and annunciated via the Det-Tronics S3 console.

SPLNG expects that Bechtel and its subcontractors will work closely with the SPLNG team during the detailed design activities. SPLNG requests that Bechtel assign personnel that are willing to promote a positive, agreeable, and willing attitude in the implementation of this important system.

Compensation for the changes specified in this Change Order is on a time and materials basis as provided in Section 6.1C and 6.2D of the Agreement.

Contractor shall commence with the performance of the change(s) described above by May 1, 2006
