In March 2014, the Company entered into an office lease (the "Lease") for its corporate headquarters located at 600 W. Germantown Pike, Suite 100, in Plymouth Meeting, Pennsylvania, and occupied the space in June 2014. The initial term of the Lease is 11.5 years and the Company plans to use the facility for office purposes.

The base rent adjusts periodically throughout the 11.5 year term of the Lease, with monthly payments ranging from $0 to $58,000. In addition, the Company will pay the landlord for its share of operating expenses and a property management fee and have paid a security deposit of $49,000. In July 2015, the Company amended the lease to increase the total leased space. The commencement of the amended lease is estimated to be in the first quarter of 2016 and will increase monthly lease payments by approximately $16,000.

The Company has capitalized $933,000 of tenant improvements to the Plymouth Meeting headquarters which have been recorded as a leasehold improvement within fixed assets on the consolidated balance sheet, offset by a corresponding amount recorded in deferred rent.

In August 2015, the Company entered into a sublease for its previous facility and completely vacated the premises.

The Company's corporate office in San Diego is located at 10480 Wateridge Circle in San Diego, California. This lease was signed in April 2013 and the building was occupied in early December 2013. The term of the Lease runs through December 1, 2023. The base rent adjusts periodically throughout the ten year term of the Lease, with monthly payments ranging from $0 to $83,000. In addition, the Company will pay the landlord its share of operating expenses and a property management fee and has paid a security deposit of $64,000.

In June 2015, the Company amended the lease for its corporate office in San Diego, California to increase the total leased space and occupy the entire building. The amendment requires the lessor to complete and pay for certain improvements to the additional space before the commencement of the amended lease which occurred in January 2016. The amended lease will increase monthly lease payments by approximately $13,000.

The Company has capitalized $773,000 of tenant improvements during the year ended December 31, 2015 on the additional corporate office space in San Diego which have been recorded as a leasehold improvement within fixed assets on the consolidated balance sheet, offset by a corresponding amount recorded in deferred rent.

Rent expense was $1.3 million, $1.2 million and $444,000 for the years ended December 31, 2015, 2014 and 2013, respectively. Future minimum lease payments under non-cancelable operating leases as of December 31, 2015 are as follows:



2016	$	1,578,000
2017	1,689,000
2018	1,661,000
2019	1,890,000
2020	1,932,000
Thereafter	9,731,000

In the normal course of business, the Company is a party to a variety of agreements pursuant to which they may be obligated to indemnify the other party. It is not possible to predict the maximum potential amount of future payments under these types of agreements due to the conditional nature of our obligations and the unique facts and circumstances involved in each particular agreement. Historically, payments made by us under these types of agreements have not had a material effect on our business, consolidated results of operations or financial condition.
