Signature of Reporting Person Date
Explanation of Responses:
( 1 )The transactions reported in this Form 4 were effected pursuant to a Rule 10b5-1 trading plan adopted by the reporting person on September 12, 2017.
( 2 )The price reported in Column 4 is a weighted average price. These shares were sold in multiple transactions at prices ranging from $15.05 to $15.65, inclusive. The reporting person undertakes to provide to Lantheus Holdings, Inc., ("LNTH") any security holder of LNTH or the staff of the Securities and Exchange Commission ("SEC"), upon request, full information regarding the number of shares sold at each separate price within the ranges set forth in this footnote (2) to this Form 4.
( 3 )These options were originally granted on April 4, 2008, and originally provided for vesting based on the level of LNTH's satisfaction of certain performance criteria for each of fiscal years 2009, 2010, 2011 and 2012. As previously reported on a Form 4 filed with the SEC on June 25, 2015, these options were amended in connection with LNTH's initial public offering on June 25, 2015 to provide for additional vesting on the third anniversary of the amendment date (or the day before any earlier expiration) of any options that remain unvested at that time. As a result, these options became exercisable on April 3, 2018, one day prior to their expiration on April 4, 2018.
