<p style="TEXT-INDENT: 25pt; MARGIN: 0in 0in 0pt;"><font style="FONT-FAMILY: Times New Roman; FONT-SIZE: 10pt;" size="2">In March 2012, the Company entered into a Tax Incentive Agreement with the Massachusetts Life Sciences Center, or MLSC, under the MLSC’s Life Sciences Tax Incentive Program, or the Program, to expand life sciences-related employment opportunities, promote health-related innovations and stimulate research and development, manufacturing and commercialization in the life sciences in the Commonwealth of Massachusetts. The Program was established in 2008 in order to incentivize life sciences companies to create new sustained jobs in Massachusetts. Under the Tax Incentive Agreement, companies receive an award from the MLSC upon attaining job creation commitment. Jobs must be maintained for at least five years, during which time a portion of the grant proceeds can be recovered by the Massachusetts Department of Revenue if the Company does not maintain its job creation commitments. As of December 31, 2012, the Company attained its job creation commitment and earned a $1.1 million job creation tax award and recognized one-fifth of the award as other income. The Company will recognize an equal portion of the award as other income over the five year period the Company maintains its job creation commitments. The unearned portion of the award is included in other liabilities in the consolidated balance sheet.</font></p>
