Safe Harbor

The foregoing presentation contains forward-looking statements that involve risks and uncertainties which could cause the company’s plans,

actions and results to differ materially from its current expectations. Such risks and uncertainties include, but are not limited to, the following: (i)

general economic, business and market conditions; (ii) the company’s ability to source and procure needed goods and services in accordance with

customer demand and at competitive prices; (iii) changes in capital availability or costs, including increases in the company’s costs of borrowing,

the amount of the company’s debt, the ability of the company to access capital markets at favorable rates, and the credit ratings of the company’s

debt; (iv) changes in consumer preferences and changes in automotive and commercial vehicle manufacturers’ production rates and their actual

and forecasted requirements for the company’s products; (v) the overall highly competitive nature of the automobile and commercial vehicle parts

industry, and any resultant inability to realize the sales represented by the company’s awarded book of business which is based on anticipated

pricing for the applicable program over its life; (vi) the loss of any of our large original equipment manufacturer (“OEM”) customers, or the loss of

market shares by these customers if we are unable to achieve increased sales to other OEMs; (vii) workforce factors such as strikes or labor

interruptions; (viii) increases in the costs of raw materials, including the company’s ability to successfully reduce the impact of any such cost

increases; (ix) the negative impact of higher fuel prices on logistics costs and discretionary purchases of vehicles or aftermarket products; (x) the

cyclical nature of the global vehicular industry, including the performance of the global aftermarket sector and longer product lives of automobile

parts; (xi) the company’s continued success in cost reduction and cash management programs and its ability to execute and realize anticipated

benefits from these plans; (xii) product warranty costs; (xiii) the cost and outcome of legal proceedings, and the impact of changes in and

compliance with laws and regulations, including environmental laws and regulations and the adoption of the current mandated timelines for

worldwide emissions regulations; (xiv) economic, exchange rate and political conditions in the countries where we operate or sell our products;

(xv) the company’s ability to develop and profitably commercialize new products and technologies; (xvi) changes by the Financial Accounting

Standards Board or other accounting regulatory bodies to authoritative generally accepted accounting principles or policies; (xvii) changes in

accounting estimates and assumptions, including changes based on additional information; (xviii) governmental actions, including the ability to

receive regulatory approvals and the timing of such approvals, as well as the impact of changes to and compliance with laws and regulations

pertaining to environmental concerns, pensions or other regulated activities; (xix) acts of war, riots or terrorism, including, but not limited to the

events taking place in the Middle East and the impact of these acts on economic, financial and social conditions in the countries where the

company operates; (xx) the timing and occurrence (or non-occurrence) of transactions and events which may be subject to circumstances beyond

the control of the company. Additional information regarding these risk factors and uncertainties is detailed from time to time in the company’s

SEC filings, including but not limited to its report on Form 10-K.

DRiVTM

Digital Valve

• Digital, not analog

– Only 16 positions, but able to switch in microseconds

• Damper– Twin tube configuration

• Valves configured in rod guide

• Otherwise uses standard components

– On-board electronics• Valve drivers, Diagnostics, Communication

– Can be configured for multiple applications• Continuously variable

• Driver-selectable, multi-position

• Electronics Control Unit (ECU)– Valve drivers located at the damper

• Control algorithm located in an integrated ECU

• The ultimate in ride and comfort

• Power actuator instead of passive damper

• Components

– Electric pump (power pack)

– Switch valve switches to compression or rebound side

– Electronic valves to regulate compression/rebound force

• Advantages

– Ability to lift or push wheel against natural direction of travel

– Greatly improved secondary ride, including reduced head toss

– Maintain desired tire to road contact under all conditions

– Vehicle load leveling and ride height management
