Item 1.01 Entry into a Material Definitive Agreement

Question 3

A: No. If an agreement becomes material to the registrant but was not material to the registrant when it entered into, or amended, the agreement, the registrant need not file a Form 8-K under Item 1.01, unless the agreement is material to the registrant at the time of an amendment to that agreement. In any event, the registrant must file the agreement as an exhibit to the periodic report relating to the reporting period in which the agreement became material if, at any time during that period, the agreement was material to the registrant. In this regard, the registrant would apply the requirements of Item 601 of Regulation S-K to determine if the agreement must be filed with the periodic report.
