10. Commitments and Contingencies

     In June 2011, we entered into a new lease agreement with 350 Riverwalk LLC. The lease is for a new corporate headquarters to be located in Lawrence, MA. The term of the lease will begin on or before June 1, 2012 and continue for an initial term of eleven years with an early termination provision after seven years, subject to certain terms and conditions. We have two, five year options to extend this lease on substantially the same terms and at rent equal to ninety-five percent of the then fair market value. In addition, we are responsible for the real estate taxes and operating expenses related to this facility. The landlord is providing us a $4.3 million tenant improvement allowance pursuant to the agreement. The future minimum annual rental payments under this agreement are estimated to be $0.8 million, $1.2 million, $1.4 million and $1.6 million, during 2012, 2013, 2014 and 2015, respectively, and $14.6 million thereafter.

     Other significant commitments and contingencies at June 30, 2011 are consistent with those discussed in Note 11 to the consolidated financial statements in our Annual Report on Form 10-K for the fiscal year ended December 31, 2010.
