Momenta Pharmaceuticals, Inc. (MNTA)

[DewDiligence]

Before the transaction posted by floblu, Shea had 108,800 options exercisable at $0.61/sh that were obtained in 2003 when MNTA was still a private company. You can see the schedule of options owned by each executive officer (as of 12/31/11) on page 34 of Form DEF-14A (the proxy for the most recent annual meeting) at: http://www.sec.gov/Archives/edgar/data/1235010/000104746912004605/a2208989zdef14a.htm .

After the latest transaction, Shea still has 62,072 of these options (and 245,650 options in all).

As floblu noted, these options did not expire until Oct 2013, and hence the exercise-and-hold maneuver is a bona fide bullish signal.
