Former United States Securities and Exchange Commission attorney Willie
Briscoe and the securities litigation firm of Powers Taylor LLP are
investigating potential claims against the Board of Directors of Medistem,
Inc. (OTCBB: MEDS) related to the acquisition by Intrexon Corporation for
shareholders. Under the terms of the definitive agreement valued at
approximately $26 million, Medistem shareholders will only receive $0.27 in
cash and $1.08 worth of Intrexon common stock for each share of MEDS stock
owned, well below the 52-week high of $2.80.
