Commitments and Contingencies

The Company leases its new corporate headquarters, continuing laboratory facility and operations centers under operating leases which expire in various years through 2018. These leases generally contain renewal options and require the Company to pay all executory costs (such as property taxes, maintenance and insurance). The Company also leases copiers and other miscellaneous equipment. These leases expire in various years through 2017.

The Company is still the primary lessee under operating leases for 16 Portamedic branch offices, which are subleased by the acquirer of the former Portamedic business. The acquirer pays 100% of the rent and other executory costs for these 16 offices in the form of a contractual obligation for the remaining lease term. If the Company is unable to assign these leases to the acquirer of the former Portamedic business, the Company will let the leases expire with no intent of renewal.

In addition, the Company is still the primary lessee under 21 operating leases related to former Portamedic offices not utilized for continuing operations and as such related costs are recorded in the reporting for discontinued operations. The Company has recorded a branch closure obligation of $0.3 million as of December 31, 2013 related to these leases.

The table below presents future minimum lease payments for operating leases (with initial or remaining terms in excess of one year) as of December 31, 2013 and includes leases from both continuing and discontinued operations, as described above.

Rental expense under operating leases of continuing operations totaled$0.7 million, $2.0 million and $1.9 million in 2013, 2012 and 2011, respectively. Rental expense in 2013 is net of sublease rental income from the acquirer of the former Portamedic operations of $0.2 million.

The Company has employment retention or change in control agreements with the executive officers of the Company for a one year period from the date a change in control occurs as further defined in the agreements.

In the past, some federal and state agencies have claimed that the Company improperly classified its health professionals as independent contractors for purposes of federal and state unemployment and/or worker's compensation tax laws and that the Company was therefore liable for taxes in arrears, or for penalties for failure to comply with their interpretation of the laws.  There are no assurances that the Company will not be subject to similar claims in the future.
