[1] Operating leases are primarily facility lease related obligations, as well as equipment lease obligations with third party vendors. The Company recognized rent expenses of $335,991, $315,134, and $324,536 in 2014, 2013 and 2012, respectively.

[2] Employment agreements include management contracts which have been revised from time to time. The employment agreement for the Company's President and Chief Executive Officer provides for a minimum salary level, which is adjusted annually at the discretion of the Company's Compensation Committee, as well as for minimum bonuses that are payable. New employment agreements for the Company's other executive officers are usually entered into annually or biennially.

[3] Research and development obligations relate primarily to clinical trials. Most of these purchase obligations are cancelable.
