Entry into Lease Amendment

On August 18, 2010, DexCom, Inc. (DexCom), entered into a First Amendment to Office Lease (the “Agreement”) with Kilroy Realty, L.P. with respect to facilities in the buildings at 6340 Sequence Drive and 6310 Sequence Drive, each in San Diego, California (the “Buildings”).

Under the Agreement, DexCom has leased approximately 102,844 square feet of space in the Buildings, and retains the right and obligation to lease an additional 25,971 square feet in the Buildings. The lease term extends through November 30, 2016. The annual rent payable by DexCom under the Agreement will be as follows:



   Annual Rent

9/1/10 - 8/31/11

   $ 1,870,651.20

9/1/11 - 8/31/12

   $ 1,938,481.32

9/1/12 - 8/31/13

   $ 2,473,509.03

9/1/13 - 8/31/14

   $ 2,561,322.94

9/1/14 - 8/31/15

   $ 2,638,567.92

   $ 2,717,470.63

9/1/16 - 11/30/16

   $ 699,500.88

In addition, under the Agreement, DexCom is obligated to pay a share of the real estate taxes and operating costs for the Buildings. The total obligation for rent under the life of the lease is $14,899,503.93, excluding real estate taxes and operating costs.

Provided DexCom is not in default under the Agreement and the Agreement is still in effect, DexCom generally has the right to extend the lease for an additional five years by giving notice to the landlord prior to the end of the initial term of the lease.


Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned thereunto duly authorized.
