Date: October 10, 2017 Subject: Adelanto Greenhouse project and Power generation requirements Reference: Two FlexEnergy Turbine® , Model GT333S, rated at 333 KW per unit Dear Mr. Khanbeigi, Attached is our proposal with multiple options for Two FlexEnergy gas turbine systems in weatherproof enclosure and Grid parallel for your Greenhouse Facility in Adelanto. The economics of the project for cost of power generation are very attractive, especially when compared with the cost of electricity from the utilities. Our proposal includes the “dual mode” feature that we discussed which provides uninterrupted power for your facility regardless of grid availability. Because the turbines can also load follow, they can modulate with demand, have redundancies and provide power at all the times. As per your requirements, we have not included any cost for heat recovery inclduing absorption chillers, however they can always be added in the future should project require. Many hours per year, we foresee just one turbine operating and thus the operating cost would drop further. Our cost analysis has been based on conservative estimation, and E&E offers the system on a turnkey installation contract. Please note the pricing as listed and itemized on page 22, and a separate financial projections are in the attachments. In brief analysis, the system in operation will offer significant operating cost reduction of $233,000 per year at 350KW per hour production, and cost of electricity at 7.7/KW. At 600 KW out put, the cost of power will be reduced to 6.2 cents per KW and an annual saving of $608,000 per year. The details are depicted in the one page financial overview for each possibility. I must add that, Flex Energy turbines, are a heavy-duty units built for 24 hours operation and highest uptime in the industry. As many of them been operating in the outdoors of Bokken Oilfields. E&E and FlexEnergy Cop. Will be providing full support services as well as field engineering and installation services on a turnkey basis For your information, E&E carries full professional insurance to include General and Product liability as well as Engineering Errors and Omission up $5 Million Dollars per project. We trust that the proposal meets with your approval and look forward to addressing any questions that you may have as you review our information. Sincerely, Amir A. Sardari Amir A.

SCOPE OF SUPPLY

Qty Two (2) Flex Turbine® GT333S Model 333SM Gas turbine(s), Rated at 333 KW at ISO conditions, 60 F, Sea Level

Each GT333S gas turbine has the standard FlexEnergy English language control panel interfaces and markings, and will be configured as follows: 480V/60Hz Generator The GT333S gas turbine will be configured with a 480V, 60Hz synchronous generator, control panel for Grid parallel operation. Grid Parallel Operation The GT333S gas turbine will be configured to operate in parallel with the local utility grid and with option to operate in grid-isolated operation based on the control of the facility’s relay protection and electrical control system (provided by customer). The latter is expected to detect the failure of utility power, disconnect the facility power bus used by the gas turbine from the utility grid, and signal the gas turbine to enter grid-isolated operation. When the facility controls detect the return of utility power, they are expected to perform a synchronized reconnection of the utility grid to the facility power bus used by the gas turbine, and direct the gas turbine to return to grid-parallel operation. Please note that all utility interconnection permits and required protection devices are the responsibility of the customer. Medium Caloric Value Fuel The GT333S gas turbine will be configured for a medium caloric value gas fuel with a Lower Heating Value (LHV) Wobbe Index between 800 and 1900 wBtu/ft3. Please see the detailed project-specific details and other fuel requirements in Section 2 Technical Data “Fuel Delivery Conditions” of this proposal. Utility grade pipeline gas will be used for this application Outdoor Enclosure - With Exhaust Stack The GT333S gas turbine will be rated and configured for outdoor installation and use in non-hazardous locations, and includes a standard exhaust stack. The ambient temperature rating is -10°F to 115°F. Factory Acceptance Test (FAT) FlexEnergy will offer extended project services to include a factory acceptance test (FAT) witnessed by the customer or authorized agent and performed according to FlexEnergy Inspection and Test Plan (ITP). Isolation Mounts The GT333S gas turbine will include a set of twelve (12) isolation mounts and associated base frame attachment hardware. The mounts are designed to help mitigate the forces and shocks experienced when transporting the GT333S between customer sites using a typical, sprung





5

suspension, flatbed trailer. Each isolation mount design includes holes for fasteners to connect the mount to an underlying structure. Integrated Waste Heat Recovery (Cogen) The GT333S gas turbine will be configured with an integral hot water heat exchanger (copper tubing with aluminum fins) suitable for cogeneration applications. CARB Certification The GT333S gas turbine will include a California Air Resources Board emissions certification as part of the Distributed Generation Program. To meet these emission levels, the customer must use pipeline natural gas while utilizing the internal waste heat recovery (co-gen) option. Additionally, the customer must operate in grid-parallel mode or have sufficient electrical load requirements to allow the GT333S gas turbine to maintain 100% power output based on the ambient conditions. Any deviation from these required operating conditions will cause the turbine to violate the CARB emissions requirements.

Ancillary Equipment

Fuel Shutoff Solenoid Valve Each gas turbine will include a ship loose fuel shutoff solenoid valve. Fuel Gas Strainer Each gas turbine will include a ship loose fuel gas strainer.

Fuel Gas Filter Each gas turbine will include a ship loose grade 7 filters. Fuel Gas Liquids Safety Sensor Each gas turbine includes a safety sensor that is designed to detect the presence of liquids (hydrocarbon or water) passing through the fuel gas train. This sensor is intended to be placed near the delivery point to the turbine and is directly integrated into the gas turbine controls.

Generator Braking Resistor (GBR) Each gas turbine will include a separate GBR module designed to facilitate starting and stopping of the GT333S gas turbine by absorbing excess energy through a resistive load bank. IP LAN Customer/Service Remote Communication Kit Each gas turbine includes an IP LAN remote communication kit that will support LAN remote communication. Provides Internet Protocol (IP) communications access to the gas turbine controls through a pre-configured (DNS globally accessible) fixed IP address. Accepts RJ45 connector from either a 10Mbps or 100Mbps Ethernet LAN. Fuel Gas Regulation

Gas pressure regulation upstream of the GT333S gas turbine will be the responsibility of the customer.

Equipment Options Supervisory Control Master (SCM) - Introduction: Supervisory Control Master Supervisory Control Master (SCM) An SCM will be included to provide group management, and import control of the GT333S gas turbines. The SCM provides single point communication and control with customer-provided utility protection relay and electrical control system to facilitate dual mode operation. Please refer to the following page for detailed information.

Tier 2 control for a group of FlexEnergy turbines will be performed by a single Supervisory Control Master (SCM) per site. The Supervisory Control Master (SCM) is used to monitor the state of the gas turbine generation buss and control the gas turbines’ electrical performance as a group. The SCM incorporates the following functions:

• Monitors the power produced by the gas turbines as a set • Import control • Turbine scheduling • Data collection • Communication to operations and service to personnel • Runs service utilities for diagnostics, log retrieval and uploads • Allows the operator to direct whether individual gas turbines operate automatically under the

control of the SCM or manually • When grid-isolated, automatically starts and stops individual gas turbines as directed by control

parameters • Sequences the gas turbine black starting process (if the turbines are equipped with black start

features) • VPN firewall provides a common point for system communications • Interfaces site specific equipment (SCADA/DCS, power meters, gas analyzers, fuel conditioning

equipment, etc.)

The SCM consists of a rack with servers, a VPN firewall, a switch and a UPS as follows: 1. The servers will perform the following functions:

a. Power management – shutting down or starting turbines to optimize the number operating for the load

b. Import control – managing the output power of the turbines to ensure import minimum required by local utility is satisfied

c. Turbine scheduling – starting or stopping turbines based on an operating schedule d. Data collection for billing purposes (if the SCM is attached to such customer-

supplied meters)





7

e. Data storage f. Sending alarm and trip emails to service or operations personnel g. Turbine controller Service Tool h. Generator Protection Unit (GPU) access i. Event log access j. Analysis log access

2. The firewall will provide internet VPN to customer and FlexEnergy headquarters: a. Customer site control b. FlexEnergy service access c. Site status monitoring d. Billing data collector (if the SCM is attached to such customer-supplied meters)

The SCM will communicate with the turbines via Ethernet busing. Scope of Supply FlexEnergy provides the SCM as an external unit in its own enclosure. Control and power connections between the gas turbine and the SCM are provided by the facility. FlexEnergy will provide up to twenty (20) hours of support and engineering services as related specifically to the SCM. If additional time is required, it will be charge at a fixed hourly rate. Assembly Layout The SCM is contained in a server rack. It is a stand-alone package suitable for floor mounting and includes casters. Construction is solid steel. Front door is steel frame with a window and back door is steel mesh. Both are lockable. Dimensions are 23.6” wide x 26.1” tall x 35.4” deep. Maximum weight of the system is 1768 lbs. The rack complies with the following industry standards:

• DIN 41491 Part I • EIA RS310-D • IEC 297-2

The SCM interface is via software accessed through a suitable PC with monitor. Input power requirements are 120VAC / 60Hz. The enclosure is designed for IP20 ingress protection. Interface Connections The SCM communicates with each gas turbine through IP LAN and/or RS485 hardwired connections installed by the customer or others from the SCM to each gas turbine. The SCM is also designed to include a connection for a customer IP LAN. This LAN connection should have a minimum of a T1 level ISP access. A typical T1 access would consist of transfer rates of approximately 1.5 Mbps both up and down regardless of the time of day. Typical Supervisory Control Master
