This shall also include operating and maintaining the Facilities to ensure that CNG vehicles can be fueled within the fueling window without interruption or delay. This shall also include provision of all scheduled and unscheduled maintenance and repairs, as well as all consumables, parts, labor, rebuilds, component replacements and materials as may be required to maintain and ensure each facility's operation and ability to fuel on demand.

b.Opal Fuels is to provide all necessary operating and maintenance support in order to meet the fueling performance requirements set forth by UPS. In order to perform the work UPS will grant the proposer access to the site and the right to utilize approved areas of the facilities and related equipment during the term of the Contract for the purpose of operating and maintaining each facility. Included in this right is the proposer's right to complete limited modifications or enhancements of the equipment as agreed upon by the proposer and UPS. Such agreement shall not be unreasonably withheld. Modifications may be made to optimize each station's ability to meet UPS's fueling performance requirements for the station and/or to improve the operating economics of each station without sacrificing its performance under these requirements.

c.Opal Fuels shall be responsible for the complete operation and maintenance of each entire facility, including fuel hoses and nozzles, methane-detection and other safety systems, throughout the duration of the Contract.

d.Opal Fuels shall be responsible for maintaining all permanent stationary fire suppression equipment, including all re-certification as required by the fire department, NFPA and any other industry standard- setting or governmental bodies. Said responsibilities shall be limited to each CNG Facility, including fueling islands.

Maintenance, Generally

a.During the term of this Operations and Maintenance Agreement, Opal Fuels shall perform Preventive and Remedial Maintenance as described herein. Repair work shall be coordinated with site personnel so as not to impede normal operations or fueling of CNG vehicles.

b.Critical service calls (those service calls reporting any disabled, impaired or malfunctioning safety system, or a natural gas leak in excess of acceptable industry standards) must be responded to and made safe within 1 hours following notification of the problem by UPS, 24 hours a day, 7 days a week, 365 days a year. For purposes of this provision, safety systems shall include, but not be limited to, fire suppression/detection systems, gas/methane detection systems, and the emergency shutdown systems.

c.Critical service call is also defined as the station running at less than 66% of the designed fueling capacity, and must be responded to within 2 hours for sites producing 800,000 GGE or greater annually and 3 hours for sites producing less than 800,000 GGE annually following

SMRH:4887-3023-7253.2 -12-

notification of the problem by UPS, 24 hours a day, 7 days a week, 365 days a year. Every effort shall be made to bring the station up to full design capacity with minimal delay to the UPS fueling operation.

d.Non-Critical service calls (those calls which do not meet the criteria of "Critical" calls) must be responded to within 4 hours following notification of problem by UPS. As long as fueling is not impacted.

e.A copy of maintenance records shall be kept at the site and must be updated on a daily basis. Should the maintenance records be kept electronically, UPS shall be allowed unrestricted access to the file, and Opal Fuels shall at all times maintain at least one current back-up copy of said file.

f.Opal Fuels shall permit trained UPS personnel to enter the compressor compound to perform routine or emergency inspections and take routine or emergency readings. It will be the responsibility of UPS to report its findings in such circumstances to the proposer.

g.Opal Fuels shall provide all tools, test equipment, replacement parts, materials, consumables, labor, and expertise, including qualified field service technicians necessary to provide the services detailed herein.

h.All maintenance and repair work shall be performed by personnel trained to do so, including training by component and system manufacturers as appropriate. All such work shall be performed in a manner consistent with the practices and procedures prescribed and recommended by the respective manufacturers.

i.Opal Fuels shall provide UPS with Internet access to the remote monitoring information and any on-site cameras installed, the pager number of the on-site technicians, and telephone contact and access to the proposer's remote c o n t r o l center.

Preventive Maintenance

a.Opal Fuels shall perform such Preventive Maintenance (PM) services as required to maintain the CNG Fueling Facility equipment in the best possible working order and in compliance with all performance and fuel- availability requirements specified herein.

b.PM services shall include, but not be limited to, calibration; diagnostics; testing; any necessary adjustments, cleaning and lubrication; replacement of worn, defective or questionable parts; minor circuit updating and modifications in accordance with the manufacturers' specifications; and handling, storage and disposal of all waste generated during PM activities in full compliance with all federal, state and local laws, as well as best industry practices.

c.Opal Fuels shall determine the scope and frequency of PM. PM shall be performed in a manner so as to ensure no disruption to the normal fueling window of the Depot, or other operations of the Depot. PM shall, at a minimum, comply with either the manufacturer's recommendations for each item of CNG equipment, or generally accepted industry standards, whichever is more stringent. The proposer shall provide UPS with a Summary List of scheduled maintenance within one month of commencing maintenance duties under the Contract. All PM schedules shall be adhered to.

Remedial Maintenance

a.Opal Fuels shall perform Remedial Maintenance (RM) when any CNG fueling facility equipment component is operating improperly or is not operating at all. Remedial maintenance shall include, at a minimum: all electrical, electronic, or mechanical adjustments; troubleshooting; alignment; and replacement of parts and/or assemblies, as required to cause failed component(s) to operate within the manufacturer's or this Contract's original equipment operating specifications and meet the performance and availability requirements of the Facility. The proposer's RM responsibilities shall also include handling, storage and disposal of all waste generated during RM activities in full compliance with all federal, state and local laws, as well as best industry practices.

b.In case any component or system fails repetitively or affects safety or critical operations, at the request of UPS, the failure or failed component(s) shall be submitted for failure analysis by the respective manufacturer(s) or an unaffiliated failure analysis company, at Opal Fuels expense.

Continued Investment/Life Cycle Replacement of CNG Station Components

Equipment components have a useful life expectancy that varies from 7 years to 25 years depending on type of component and daily use. The chart below identifies the various equipment located at existing UPS CNG stations requiring replacement through 2032 as required by each OEM based on current use (Appendix A). As part of this all-inclusive agreement, OPAL Fuels will replace the equipment below along with the normal ongoing daily maintenance required to operate each station.

Any additional equipment that has a major unforeseen failure not listed below that requires full replacement during this agreement period will be repaired or replaced to continue normal day to day operations as part of the all-inclusive price.

Based on current operations, there will not be any additional capital by UPS required to replace or upgrade existing equipment at each site location. This Life Cycle clause is in addition to the O&M agreement for consumables, parts, labor, rebuilds, component replacements and materials required to maintain and ensure each facilities operation and ability to fuel on demand during the agreement term as each site ages.
