NOTE 10. COMMITMENTS AND CONTINGENCIES Leases In April 2012, the Company entered into an office and laboratory lease agreement to lease approximately 52,500 rentable square feet in Newark, California commencing on December 1, 2012. The Company was obligated to lease approximately 8,000 additional rentable square feet commencing no later than December 1, 2015. The Lease will expire on November 30, 2022. However, the Company has the right to renew the lease for one additional five year term, provided that written notice is made to the landlord no later than 12 months prior to the lease expiration. The Company will have the one-time right to terminate the lease in its entirety effective as of November 30, 2017 by delivering written notice to the landlord on or before December 1, 2016. In the event of such termination, the Company will pay the landlord the unamortized portion of the tenant improvement allowance, specified additional allowances made by the landlord, waived base rent and leasing commissions, in each case amortized at 8% interest. Our previous lease in Menlo Park, California ended in January 2013. The Company was allowed to control physical access to the premises upon signing the lease. Therefore, in accordance with the applicable accounting guidance, the lease term was deemed to have commenced in April 2012. Accordingly, the rent free periods and the escalating rent payments contained within the lease are being recognized on a straight-line basis from April 2012. The Company will pay approximately $12.1 million in aggregate rent over the remaining term of the lease for the above premises. Deferred rent for the years ended December 31, 2014 and 2013 was approximately $1.7 million and $1.5 million, respectively. In December 2013, the Company entered into an operating lease agreement with Enterprise FM Trust (Enterprise) for the lease of vehicles to be used by the Company's sales force. The Company began receiving vehicles in the second quarter of 2014, with the lease terms ranging from 18 to 36 months. T
