The Company’s warranty policy provides for the replacement of defective parts.  In certain large contracts, the Company has agreed to negotiate in good faith a product warranty in the event that an epidemic failure of its parts was to take place. To date there have been no significant occurrences.  Warranty expense historically has been immaterial.

The Company provides a limited indemnification for certain customers against intellectual property infringement claims related to the Company's products. In certain cases, there are limits on and exceptions to the Company's potential liability for indemnification relating to intellectual property infringement claims.  To date, the Company has not incurred any significant indemnification expenses relating to intellectual property infringement claims.  The Company cannot estimate the amount of potential future payments, if any, that the Company might be required to make as a result of these agreements, and accordingly, the Company has not accrued any amounts for its indemnification obligations.
