Toyota has launched Corrosion-Resistant Compound (“CRC”) campaigns for particular vehicles
registered in certain cold climate states with high road salt use (“Cold Climate States”) to
address the potential for greater than expected levels of vehicle frame corrosion. This “CRC:
Campaign Process Overview” provides a general description of the process being used by
Toyota dealers to apply CRCs to vehicle frame surfaces.

The CRC Campaigns entail the application of two Class IIIB combustible liquids ("CRCs”) to an
eligible vehicle’s frame — one to the exterior and the other to interior frame surfaces — using a
Vaupel HSDR 3300 spray gun. Toyota has issued dealers 2 of these spray guns, with
instructions to dedicate one to the interior and the other to the exterior CRC and to use these
guns only for the CRC campaigns. The CRC campaigns are occurring indoors in an existing
dealership service area. Dealers have been instructed to comply with fire, zoning, air and
building codes when conducting the CRC campaigns, including to comply with all recordkeeping
and material handling requirements.

The CRC campaigns process consists of three primary steps:
1. Work Area Setup
2. Vehicle Inspection and Preparation
3. CRC Application

Step 1: Work Area Setup. Dealers are conducting the CRC campaigns in a dedicated work
space in the dealership’s service area that has a vehicle lift, is well ventilated, is located away
from other vehicles, is at least 20 feet away from open flames, spark-producing equipment and
drying, curing or fusion apparatuses, has appropriately-rated fire extinguishers in the immediate
vicinity and can be sectioned off with temporary partitions. No physical alteration of the
workspace or installation of new equipment is required for the CRC campaigns.

Step 2: Vehicle Inspection and Preparation. Dealers should employ the following procedures
to prepare their service areas and vehicles for spraying.

> Visually Inspect for Frame Perforation Based On Toyota inspection Criteria. if the vehicle

frame has perforation in excess of Toyota's inspection criteria, then it will be replaced and
CRCs will not be applied.

> Clean Frame. \t may be necessary to clean the frame with mechanical methods, including
pressure washing. No chemicals or solvents will be used to clean the frame.

> Place Vehicle on Lift’ Raise the vehicle using the vehicle lift; remove certain vehicle
components as necessary to apply the CRCs to the vehicle frame (e.g., tires and wheels,
Spare tire, engine under cover, bumper cover, etc.).

>» Work Area Setup. Place tarp beneath vehicle and set up temporary partitions around
vehicle. Tarps are intended to capture limited overspray and to facilitate clean-up.

> Prepare Frame. Manually remove rust from frame using scraper, chisel, and/or
compressed air (e.g., air scalers).
Page 1 of 2

> Clean Frame (Secondary Cleaning). Manually remove any remaining rust or dirt using
wire brush and air nozzle.

~ Secondary Visual inspection. Visually inspect the frame to ensure no perforation meeting
Toyota's criteria was uncovered during the manual rust removal and cleaning process.

> Temperature Measurement. Use an infrared thermometer to ensure the vehicle exhaust
system has sufficiently cooled prior to any spraying.

~ Mask Parts. Mask areas not to be sprayed (e.g., drive shaft, brake/hub assemblies,
exhaust, other electrical components, etc.).

> Attach Plastic Sheet: Attach plastic sheet to frame capture any internal CRC that may drip
through small holes in the frame; use magnets to suspend a plastic sheet underneath the
frame.

Step 3: CRC Application. Dealers should apply the CRCs to vehicle frame surfaces as
follows:

7 Setup Spray Gun for Internal Frame CRC Application. Prepare the Vaupel HSDR 3300
spray gun dedicated to the interior CRC.

~ Apply CRC to Interior of Frame. Insert select spray nozzle a specified distance into holes
in the frame identified in the Technical Instructions for the particular CRC campaign.
Press spray gun trigger and pull out nozzle at fixed speed while spraying interior surface
of frame with the CRC. Complete the number of laps indicated in the Technical
Instructions for each hole. When finished, wipe away any residual CRC on the frame's
exterior with cloths or paper towels.

~ Remove Plastic Sheet Suspended From Frame.

* Install Foam Blocks and Body Plugs. After spraying the CRC to the frame interior, insert
foam blocks and body plugs to keep CRC in the frame's interior and to limit water and
road spray from entering the frame or cross-members.

7 Setup Spray Gun for External Frame CRC Application. Prepare the Vaupel HSDR 3300
spray gun dedicated to the exterior CRC.

> Apply CRC to Frame Exterior. Following spray gun set up, hold the unidirectional
handheld spray nozzle a distances from the frame surface specified in the Technical

Instructions for the particular CRC campaign. Press spray gun trigger and spray the CRC
on the top of portion of the frame by moving spray nozzle at fixed speed across frame
surface.

* Apply External Frame CRC to Lift Contact Points. Lower the vehicle halfway, reinstall
wheels, lower vehicle and apply CRC to the areas where the lift arms touched.

* Raise Vehicle to Facilitate Post Spray Vehicle Restoration. Raise the vehicle and remove
Protective tape and all fire retardant sheeting and plastic coverings.

* Take Final Steps Necessary to Return Vehicle Customer. Reinstall components (such as
the engine undercover); lower vehicle from lift; complete reinstallation of other components.

(such as the rear bumper cover); and place vehicle in a location where CRCs can cure for
24 hours before returning vehicle to customer.

EXTINGUISHING MEDIA: Small Fires: Dry chemical, CO, water spray, or regular foam. Large Fires: Water
spray, fog, or regular foam. Move container from fire area if you can do it without risk. Apply cooling water to sides
of containers that are exposed to flames until well after fire is out. Stay away from ends of tanks. For massive fire in
cargo area, use unmanned hose holder or monitor nozzles. If this is impossible, withdraw from area and let fire burn.
Withdraw immediately in case of rising sound from venting safety device or any discoloration of tank due to fire.

CORROSION-RESISTANT COMPOUND CAMPAIGNS
DEALER INFORMATION PACKET

CRC CAMPAIGN AIR EMISSION CALCULATION SUMMARY

Toyota Motor Sales, U.S.A., Inc. (TMS) has prepared this Summary to support its dealers
conducting the Corrosion-Resistant Compound (“CRC”) campaigns. This Summary explains
the calculation of volatile organic compounds (VOCs) and particulate matter (PM) emissions
from the CRC campaigns.

I EXPLANATION OF VOC & PM EMISSION FACTORS

For CRC campaigns, Toyota dealers will use a Vaupel HSDR 3300 spray gun to apply two
different CRC materials to the vehicle frame surfaces: (1) Noxudol 300 S (exterior frame
surfaces) and (2) 712 AM (interior frame surfaces). Toyota dealers will be supplied with a pre-
packaged “kit” that contains exactly the amount of each CRC needed for the vehicle.

The amount of each CRC needed depends upon the vehicle’s frame dimensions and openings;
due to slight variations among the different makes and model years of vehicles covered by the
CRC campaigns, the amount of each CRC applied will not be the same for all vehicles. For the
CRC campaigns, Toyota dealers will select among 3 different pre-packaged “kits” (each with
different amounts of the CRCs) depending upon the particular make and model year of the
vehicle being processed:

» 00289-TOOKT-DS -- 0.792 gallons (3 liters) of Noxudol 300 S and 0.264 gallons (1 liter) of
712AM

» 00289-SOOKT-DS — 0.792 gallons (3 liters) of Noxudol 300 S and 0.528 gallons (2 liters) of
712AM

+ 00289-T01KT-DS -- 0.528 gallons (2 liters) of Noxudol 300 S and no 712AM

TMS has developed a CRC Campaign Vehicle Production Log (VPL) that dealers can use to
document compliance with air permitting requirements by tracking vehicle processing and
calculating VOC and PM emissions from the CRC campaigns. As explained below, the VPL
incorporates an emissions calculation for each of the three kits that relies on conservative
assumptions. Thus, this calculation likely overstates emissions.

Page 10f5

A. VOC Emissions

The VPL emissions calculation for VOCs assumes that all of the VOCs contained in Noxudol
300 S (0.09 pounds per gallon) and 712AM (0.165 pounds per gallon)! will be emitted to the
ambient air during the CRC application process and/or post-application curing. Accordingly, the
emission factors used in the VPL calculations account for the total quantity of VOCs in each kit
type.

The following table summarizes the VOC emissions calculations for each CRC kit type.
