Melanie:

Per your request of last week, please find attached pricing information for servicing the John Deere T4i exhaust DOC/DPF (brick) equipment.

Marsh Creek used the community of Nikolski for this quote, as they are currently traveling to Nikolski for service work and have current travel cost information for that community. Nikolski is slightly further out the Aleutian Chain than the community of Chignik, Alaska (one of the three representative communities used as an example in our letter of last week to you), and therefore the travel costs (and cost of brick service) for Nikolski are slightly higher than for our three sample communities.

please contact me if you need any further information

Subject: Nikolski Brick Replacement Estimate

The following is an estimate of what the cost would be to replace an exhaust Catalyst/ DPF assembly (brick) on a John Deere IT4 diesel generator set engine. This estimate will include the cost of the job, along with pricing for the three different sizes of bricks that would be used on AEA specified generator set engines.

Labor (Estimated with (2) days travel) 40 x $125.00 per hr.: $ 5,000.00 Airfare (At cost + $50.00, off season): $ 1,500.00 Lodging (3 nights @ $150.00/ night): $ 450.00 Per Diem (4 days @$60/day): $ 240.00 Other Direct Costs (Parking, excess baggage, etc.) $ 40 0.00

Subtotal minus parts: $ 7,590.00

Brick for 117kW engine (includes freight to Anchorage): $ 2,710.00 Total for replacement of 117kW brick: $10,300.00

Brick for 229kW engine (includes freight to Anchorage): $ 7,000.00 Total for replacement of 229kW brick: $14,590.00

Brick for 372kW engine (includes freight to Anchorage): $ 8,700.00 Total for replacement of 372kW brick: $16,290.00

Total to replace all three bricks in one trip: $26,000.00

Please keep in mind that this is a theoretical estimate of what the described work would cost. Nikolski is served by aircraft only a few days out of the week, and the duration of time spent onsite is based solely upon the cooperation of weather conditions, which tend to be marginal at best in the Aleutians. Any standby time experienced due to weather delays will be billed at 8hrs labor per day plus expenses.2000 E. 88 Ave. ● Anchorage, AK 99507 ● Tel - (907) 258-0050 ● Fax - (907) 279-5710 MARSH CREEK, LLC, a certified ANC 8(a) Company Furthermore, please note that this estimate is for travel to Nikolski during the off season. Travel during the fishing season will cost $1000-$1500 more for airfare, and advance notice will be required as well for reserving a seat on the flight, as all flights tend to be overbooked during the fishing season.

Please feel free to contact me with any questions or concerns that you may have.

Thank You,
