                Pandanus Partners L.P. ("Pandanus") owns shares of FIL
Limited ("FIL") voting stock. While the percentage of total voting power
represented by these shares of FIL voting stock may fluctuate as a result
of changes in the total number of shares of FIL voting stock outstanding
from time to time, it normally represents more than 25% and less than 50%
of the total votes which may be cast by all holders of FIL voting stock.
Pandanus Associates, Inc. ("PAI") acts as general partner of Pandanus.
Pandanus is owned by trusts for the benefit of members of the family of
Edward C. Johnson 3d but disclaims that any such member is a beneficial
owner of the securities reported on this Schedule 13G.



                This filing reflects the securities beneficially owned, or
that may be deemed to be beneficially owned, by FIL, certain of its
subsidiaries and affiliates, and other companies (collectively, the "FIL
Reporters"). This filing does not reflect securities, if any, beneficially
owned by certain other companies whose beneficial ownership of securities
is disaggregated from that of the FIL Reporters in accordance with
Securities and Exchange Commission Release No. 34-39538 (January 12, 1998).

RULE 13d-1(k)(1) AGREEMENT


                The undersigned persons, on June 9, 2014, agree and consent
