4. The TowFLEXX® Advantage! Towing and maneuvering Aircraft with Tow- FLEXX® (powered by Flyer-Truck®) is easy, much safer, and definitely the most advanced Method of handling Fixed Wing and Helicopter Aircraft. Our advanced ROTV's signifi- cantly increase the number of aircraft you can place in any hangar. The highly flexi- ble and versatile equipment can create up to 40% additional hangar space (in average 35% depending on the mix of aircraft), gener- ating additional revenue for the FBO or hangar owner / operator. Irrespective of for- ward or reverse motion, our ROTV's will always be the un- matched tool and solution to create real additional space inside the hangar. Turning the ROTV, turning the nose gear, and moving the aircraft are three different actions. The unique TowFLEXX® 360° technology feature makes the difference. Overall this results in much less space requirements and elevates the hangar and apron utilization. towing Conventional Tow Tug with Towbar Easy Exit Path Exit Path required The conventional method of hangar utilization. The very same hangar utilizing Underutilized Hangar Space Thanks to TowFLEXX®, hangar utilization and revenue can be increased up to 40%. The hangar is under-utilized and not used at full capacity. The hangar owner is losing revenue. 4

5. TowFLEXX® ROTV’s (Remote Operated Tug Vehicle’s) provide many Advantages. One major Benefit is the Ability to generate additional Parking & Hangar Space. Moving an aircraft the conventional way with a tug and towbar, or a traditional towbarless tug, requires a lot of space. In order to steer the aircraft considerable movement is required. Turning the nose gear can only be achieved by moving the air- craft forward or back. Extreme cau- tion is required to prevent nose gear oversteering and to avoid damage to the sensitive nose wheel landing gear. The aircraft must be moved several yards before the nose gear can be turned and to steer in a new direction. This conventional method requires significant space. Area required to turn an aircraft 90° with a conventional tow bar & tug Unmatched flexibility thanks to the revolutionary and proprietary 360° turn feature. You can park and position aircraft by utilizing available space that’s not reachable with a conventional tug.

6. TowFLEXX® ROTV’s (Remote Operated Tug Vehicle’s) are more flexible and simultaneously protect your Aircraft like no other Product in this Category. The TowFLEXX® Difference! Thanks to the unique 4-wheel 360° steering and drive control technology, the advanced TowFLEXX® 600 RC can literally turn any aircraft on the spot. That’s highly innovative, provides more space, additional revenue for the operator, and is un- matched compared to any other product in the market. Area required to turn an aircraft 90° or 360° with Operating in tight areas, and generating addi- tional hangar space is the hallmark of Tow- FLEXX®. Operating conventional tow tractors with towbar, or conventional towbarless tugs is cumbersome and time consuming. Reaching corners or parking an aircraft against a wall is impossible with those old technolo- gies. Conventional tugs also require significant room for an exit path. Hangar Wall Conventional Tow Tug with Towbar Exit Path Towbarless Tug Hangar Wall Exit Path Hangar Wall Additional Hangar Space Exit Path TowFLEXX® is providing unmatched flexibil- ity and generates additional hangar space. Unique and “best-in-class”. The smart 360° steering technology compen- sates rotational resistance and equalizes transverse forces. No gimbal mounted platform and no hydraulic compensators are required. 360° 360° 360° 360° 6
