OWNER: Rio Grande LNG, LLC
EFFECTIVE DATE OF CHANGE ORDER:
March 10, 2026
CONTRACTOR: Bechtel Energy Inc.
TITLE: LP-HP FUEL GAS SYSTEM MODIFICATIONS - INSTALLATION


BACKGROUND:

Owner previously executed Change Order EC00192_SC0113 for HP Fuel Gas Heaters (1E-5201, and 2E-5201) in Trains 1 and 2. Under this Change Order, the Contractor is responsible for engineering, specifying, procuring, and delivering to site a Fuel Gas Heater for each train.

Additionally, Owner previously executed EC00190_SC0111 for HP Fuel Gas Mixing Drums (1V-5204, and 2V-5204) in Trains 1 and 2. Under such Change Order EC00190_SC0111, the Contractor is responsible for all work required to engineer and specify (including mechanical and process data sheets), procure (including material requisition, purchasing, vendor print review, and resolution of technical queries), and deliver an HP Fuel Gas Mixing Drum based on two high N₂ feed gas scenarios: (a) End Flash Gas (“EFG”) system implemented, with flash gas routed to Boil-off Gas (“BOG”) Compressors and the HP fuel gas system; and (b) EFG not implemented, with rundown and flash in LNG tanks to BOG Compressors and degraded LNG production.

This Change Order EC00235_SC0142 includes installation scope and remaining procurement not included in Change Order EC00192_SC0113 and Change Order EC00190_SC0111 for the following:
1.Installation of new HP Fuel Gas Mixing Drums (1V-5204 and 2V-5204)
2.Installation of new HP Fuel Gas Heaters (1E-5201 and 2E-5201)

CHANGE:

Contractor shall procure the remaining equipment and materials and install HP Fuel Gas Mixing Drums (procured under Change Order EC00190_SC0111), HP Fuel Gas Heaters (procured under Change Order EC00192_SC0113) and incorporate the LP-HP Fuel Gas System Modifications (as originally described in Change Order EC00192_SC0113) into the Facility. This scope includes upsize of PSV-520005A/B and associated piping, and also includes meeting the updated design requirements for the fuel gas system as indicated in the below marked-up Utility Design Basis – Unit 52 – Fuel Gas (26251-100-3DR-V04-52001 / RG-BL-052-PRO-DES-00001):


[***]


This Change Order does not change the basis of design for the feed gas composition for which the Facility is designed as defined in Attachment A, Schedule A-2, Section 7.4.1 Table 3: Feed Gas Composition.

The Work implemented under this Change Order will result in a reduction to certain margins within the existing Train design. This includes, but is not limited to a) reduction in instrument air system margins due to addition of instrument air users, and b) spare capacity of the electrical and control systems such as spare I/O. This Change Order excludes changes to restore margins eroded by this change. Notwithstanding the requirements of section 6.2A, section 6.4 and section 6.8(b) of the Agreement and subject to the requirements of section 6.10, should it be determined, in Contractor’s reasonable opinion, that the cumulative impact of Change Orders result in a material reduction of those margins, then Owner and Contractor shall



mutually determine to execute either a technical deviation for such reduction in margin or a separate Change Order to restore such margins.

Contractor specifically excludes any Warranties or guarantees that implementation of the fuel gas system updates into the Facility as described in the Change section above will have the outcome that Owner intends with respect to enabling the combustion of higher nitrogen fuels, or mitigating risk of future changes to the fuel gas system.

This Change Order does not include any re-rating by Baker Hughes and/or the Licensors; if any assessments are subsequently required by Owner those shall be subject to a separate Change Order.

Notwithstanding the requirements of section 6.2A, 6.4 and section 6.8(b) of the Agreement and subject to the requirements of section 6.10, if the scope performed under this Change Order delays the commencement, prosecution or completion of the Work, Contractor shall be entitled to a separate Change Order for adjustment to the Key Dates, if such delay affects the performance of any Work that is on the critical path of the Monthly Updated CPM Schedule.
