Registration. The Common Stock is registered pursuant to Section 12(b) of the Exchange Act and is currently listed and quoted on the Principal Market under the trading symbol “HST”, and the Common Shares have been or will have been listed on the Principal Market prior to the delivery of the first Issuance Notice hereunder, subject to notice of issuance. An “automatic shelf registration statement” as defined under Rule 405 under the Securities Act on Form S-3 (File No. 333-188059), which contains a base prospectus, to be used in connection with the public offering and sale of the Common Shares, has been filed with the Commission not earlier than three years prior to April 25, 2013 and became effective upon filing. Such registration statement, as amended, including the financial statements, exhibits and schedules thereto, at each time of effectiveness under the Securities Act, including any required information deemed to be a part thereof at the time of effectiveness pursuant to Rule 430B under the Securities Act or the Exchange Act, and the base prospectus constituting a part of such registration statement, together with the Prospectus Supplement (as defined in Section 5.01(k)) and any pricing supplement relating to a particular issuance of the Issuance Shares and filed pursuant to Rule 424(b) promulgated by the Commission under the Securities Act (each, an “Issuance Supplement”), including all documents incorporated or deemed to be incorporated therein by reference pursuant to Item 12 of Form S-3 under the Securities Act, in each case, as from time to time amended or supplemented, are referred to herein as the “Registration Statement” and the “Prospectus,” respectively.

As used in this Agreement, the terms “amendment” or “supplement” when applied to the Registration Statement or the Prospectus shall be deemed to include the filing by the Company with the Commission of any document under the Exchange Act after the date hereof that is or is deemed to be incorporated therein by reference.
