(7) COMMITMENTS AND CONTINGENCIES (a) Lease Obligations Since 1983 our headquarters has been near South Station in downtown Boston at 201 and 207 South Street. In December 2006, the Company sold its owned headquarters buildings in Boston, Massachusetts and leased back 25,200 square feet for two years expiring December 2008. In November 2008 the Company signed a lease amendment for its headquarters’ offices in Boston in the existing building for approximately 14,400 square feet for three years with a six month termination option starting July 1, 2010. In May 2010 we signed a second lease amendment extending the term of the lease to April 30, 2016 with a six month termination option starting December 1, 2011. In August 1996 we entered into a lease for a 77,428 square feet manufacturing and warehousing facility at 645 Summer Street, Boston, MA. The term of this lease expired in August 2006 and we began the planned move of our manufacturing and warehousing facility to Tijuana, Mexico. In August 2006 we signed a lease for a 35,575 square foot manufacturing and warehousing facility in Tijuana, Mexico with an initial lease term from October 2006 to May 2007, with five two-year options thereafter. In February, 2007 we renegotiated the first renewal term and signed a one-year extension starting in May 2007, with five two-year options thereafter. We signed another one-year extension starting in May 2008. In March 2009 we signed a one-year lease with one one-year option for a smaller facility for lower cost. In March 2011 we signed a one-year lease extension starting May 1, 2011, with three one-year renewal options thereafter. In September 2005 the Company entered into a two year office lease consisting of 2,400 square feet at 2 Kings Road, Fleet, Hants, U.K for its U.K. sales office. In September 2007 the lease was continued on a month-to-month basis with a 3 month cancellation notice required by the Company or the landlord. In September, 2008 the Company signed an Office Service Agreement, which is an office rental agreement, rather than a lease. The rent is paid monthly, with a three month cancellation notice period. Rent expense for all of the Company's leases was $438,815 in 2009 and $363,843 in 2010. As of December 31, 2010, the Company's estimated future minimum committed rental payments, excluding executory costs, under the operating leases described above to their expiration or the earliest possible termination date, whichever is sooner, are $325,710 for 2011 and $291,806 for 2012. (b) Contingencies The Company is party to various lawsuits and administrative proceedings arising in the ordinary course of business. The Company evaluates such lawsuits and proceedings on a case-by-case basis, and its policy is to vigorously contest any such claims which it believes are without merit. The Company's management believes that the ultimate resolution of such matters will not materially and adversely affect the Company's business, financial position, results of operations or cash flows. In February 2009 the Company was named as one of 15 defendants in a patent infringement lawsuit filed in the United States District Court for the Eastern District of Texas by Finoc Design Consulting Oy of Oulu, Finland. The complaint claimed that the Company had been and was then infringing on U.S. patent 6,850,560, dated February 1, 2005, by offering for sale, selling, and providing service and support to customers of its wireless xDSL products. The Company believes that the basis for the infringement charge relates to certain chipsets in the Company's wireless xDSL products that were obtained from Conexant Systems, Inc (“Conexant”). All of the Company’s wireless xDSL products use Conexant ADSL chipsets. The lawsuit was dismissed with prejudice on August 26, 2009.
