{1}------------------------------------------------

There are two models of Scooters in the Panther series. These are the Panther LX - 4 and the Panther MX - 4. A brief description of each is as follows.

#### Panther LX - 4

The Panther LX - 4 scooter is basically the same as the Lynx LX - 3 scooter except that the Panther LX -4 is a four wheeled vehicle whereas the Lynx LX - 3 is a three wheeled vehicle. It includes the same transaxle motor drive system, braking system, adjustable seat, upholstery, covers, tiller handle and throttle control as the Lynx LX - 3. Additionally, it incorporates the same Penny & Giles "Solo 60" motor controller and the Lynx version and it has an on board battery charger.

Because the Panther LX - 4 is a four wheel vehicle, the welded steel frame is slightly different than the Lynx version. While the rear section of the frame is basically the same, the front portion differs such that it can accept two front wheels as opposed to one wheel on the Lynx. With these exceptions, the Panther LX - 4 is basically the same as the Lynx LX - 3.

#### Panther MX - 4

The Panther MX - 4 is the largest scooter in the Invacare Lynx/Panther. Like the Panther LX -4 , the Panther MX - 4 is a four wheeled vehicle. It has the same intended function and use as the others, and consists of the same technology and construction. Like the others, it basically consists of a welded steel frame, transaxle drive mechanism. braking system and seat assembly. Also, it includes a tiller handle for steering, and a throttle control to engage and disengage scooter motion in both the forward and reverse directions.

The Panther MX - 4 differs from the others in the Lynx/Panther series in that it is designed as a heavy duty, more durable scooter with a recommended weight limitation of 400 lbs. maximum. It is larger and heavier than the others, and includes more options and features. As such the frame, transaxle drive and braking system are different from the others and , the Panther MX - 4 scooter is powered using a Penny & Giles model "Solo 110" motor controller.

#### Substantial Equivalence

Products which are substantially equivalent to the Invacare Action Cat three wheeled scooter (K962583, 12/18/96) the Mega Motions Inc. Mega 4 scooter (K982144, 4/14/99), and the Pride Mobility Inc. Celebrity (K944939, 11/7/94). Each of these products are motorized, three and four wheeled scooters with the same intended function and use of providing mobility to persons limited to a seated position. All are all constructed from the same basic materials and components, all have the same basic operational principles and all use DC batteries as their source of power. Drive mechanisms and braking systems are also similar as are performance specifications for speed, acceleration, deceleration, turning radius and braking.
