The Company’s industry is characterized by frequent claims and litigation, including claims regarding intellectual property and product liability. As a result, the Company may be subject to various legal proceedings from time to time. The results of any current or future litigation cannot be predicted with certainty, and regardless of the outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources, and other factors. Any current litigation is considered immaterial and counter claims have been assessed as remote.

The Company has entered into employment agreements or other arrangements with certain named executive officers and various other members of management, which provide salary continuation payments, bonuses and, in certain instances, the acceleration of the vesting of certain equity awards to individuals in the event that the individual is terminated other than for cause, as defined in the applicable agreement.

In the course of operating its business, the Company has entered into, and continues to enter into, separate indemnification agreements with the Company’s directors and executive officers, in addition to the indemnification provided for in the Company’s amended and restated bylaws. These agreements may require the Company to indemnify its directors and executive officers for certain expenses incurred in any action or proceeding arising out of their services as one of the Company’s directors or executive officers.
