(b) 401(k) Profit Sharing Plan

Employees are offered the opportunity to participate in the Company’s 401(k) Profit Sharing Plan ("the 401(k) Plan"), which is intended to be a tax-qualified defined contribution plan under Section 401(k) of the Internal Revenue Code. Under the 401(k) Plan, employees are eligible to participate on the first day of the month following the date of hire. Eligible employees may contribute up to 60% of their salary to the 401(k) Plan. Subject to certain limitations, the Company may make a discretionary profit sharing contribution at an amount determined by the board of directors of the Company.

The Company more often than not indemnifies its customers against damages and costs resulting from claims of patent, copyright, or trademark infringement associated with use of the Company’s products. The Company historically has not been required to make any payments under such indemnifications. However, the Company continues to monitor the circumstances that are subject to the indemnifications to identify whether it is probable that a loss has occurred, and would recognize any such losses under the indemnifications when those losses are estimable.

In addition, the Company warrants to customers that the Company’s products operate substantially in accordance with the software product’s specifications. Historically, no costs have been incurred related to software product warranties and none are expected in the future, and as such no accruals for software product warranty costs have been made. Additionally, the Company is involved in various claims arising in the ordinary course of business. In the opinion of management, the ultimate disposition of these matters will not have a material adverse effect on the financial position or results of operations of the Company.
