PFS Overview  PFS Goal: Provide products and services that enable the use of natural gas  Wholly owned subsidiary of Chesapeake Energy – 2 nd largest producer of natural gas in US behind XOM  GE partner company – CNG In A Box™ system 3

Conversion Overview  EPA 2010 ISX15 (MY 2010 – 2012)  Emissions equivalent or less than diesel operation  Capability of operating on 100% diesel retained  65% maximum gas substitution; majority of applicable torque/speed map in 55% - 65% range  Similar aftertreatment duty cycle – i.e. temps, frequency of regen and catalyst degradation 4

Conversion Overview  Mechanically simple system  Single point post turbo injection  Cylinder pressures and engine temperatures similar to diesel-only operation  Comparable BSFC in dual-fuel operation  Identical power map in dual-fuel mode 5

Diesel Displacement Testing – OKC  485 hp/1650 ft-lb  Removable diesel tank weighed before and after each run 4 runs – 2 diesel and 2 dual fuel  Diesel DNG Distance 109.6 mi 109.4 mi Time 1:44 1:43 Diesel Used 131 lbs 66 lbs Diesel Used 18.6 gal 9.4 gal Overall Diesel Displacement – 50%   Assuming $3.95/gal diesel*, $1.69/gge CNG, and 5.9 mpg result in a $20 fuel savings over 110 miles or 26% fuel cost reduction 11 * AAA Daily Fuel Gauge Report – 3/12/13

Diesel Displacement Testing – Phoenix  400 hp/1650 ft-lb  3 rd party independent test  Removable diesel tank weighed before and after each run  4 runs – 2 diesel and 2 dual fuel Diesel DNG Distance 215 mi 215 mi Time 3:28 3:28 Diesel Used 183.1 lb 91.5 lb Diesel Used 26.0 gal 13.0 gal  Overall Diesel Displacement – 50%  Assuming $4.10/gal diesel*, $1.69/gge CNG, and 8.1 mpg result in a $30 fuel savings over 215 miles or 27% fuel cost reduction 12 * AAA Daily Fuel Gauge Report – 3/12/13

Fuel Storage Options  (3) 18.5" x 78" CNG Rack (behind cab) – Approximately 1,300 lbs incremental weight – 45 dge; 500 miles before NG refuel required  (1) 26” x 80” CNG Tank (frame rail mount) – Approximately 350 lbs incremental weight – 38 dge; 420 miles before NG refuel required  (1) 73 gal LNG tank (frame rail mount) – Approximately 650 lbs incremental weight – 38 dge; 420 miles before NG refuel required  (1) 120 gal LNG tank (frame rail mount) – Approximately 985 lbs full – 63 dge; 675 miles before NG refuel required 14

Economics  Turnkey conversion price of $25k - $35k – $0.20 per mile fuel savings* – 12 - 18 month payback*  Warranty – Conversion warranty mirrors Cummins basic mechanical warranty (2yr/250k mile/6,250 hr) – OEM warranty remains intact after conversion – Must be able to link root cause of failure to conversion to void warranty – Dealer relationship important *$1.69 gge CNG; $3.85 gal diesel; 400 miles/day 15
