MEDICINOVA INC

In December 2017, we executed a sublease agreement for our San Diego headquarters (Sublease) with Cardinal Health 127 Inc., the sublessor, to which Irvine Company, the master lessor, had provided its consent. The Sublease was for approximately 4,400 square feet and had a term of four years and one month. We have extended this Sublease for an additional 5 years through January 31, 2027.

In June 2005, we leased office space in Tokyo, Japan under a non-cancelable operating lease with an original expiration date of May 2013 and an auto-renewal two-year extension. The lease was renewed in May 2023 and has a term of two years with an auto-renewal, two year extension. We have no laboratory, research or manufacturing facilities, and we currently do not plan to purchase or lease any such facilities, as such services are provided to us by third-party service providers. We believe that our current facilities are adequate for our needs for the immediate future and that, should it be needed, suitable additional space will be available to accommodate expansion of our operations on commercially reasonable terms.
