(2) In March 1997, an unrelated third party filed a lawsuit against us alleging breach of a written agreement. In April 2002, we settled the dispute and agreed to pay a total of $30.0 million in ten equal annual installments of $3.0 million per year beginning in June 2002. See Note 12 " Legal Proceedings " for further discussion. (3) We had certain purchase obligations as of September 24, 2010 representing non-cancelable commitments to purchase inventory from our manufacturing supply base in fiscal 2011. Rental expenses under operating leases were $7.7 million, $7.9 million and $8.7 million for fiscal 2008, 2009 and 2010, respectively. These amounts include expenses for rent payable to our principal stockholder of $1.4 million, $1.3 million and $1.4 million for fiscal 2008, 2009 and 2010, respectively. We are party to certain contractual agreements under which we have agreed to provide indemnifications of varying scope and duration to the other party relating to our licensed intellectual property. Historically, we have made no payments for these indemnification obligations and no amounts have been accrued in our consolidated financial statements with respect to these obligations. Due to their varying terms and conditions, we are unable to make a reasonable estimate of the maximum potential amount we could be required to pay.
