Under the terms of the transaction, Optimer shareholders will receive only $10.75 in cash and a Contingency Value Right that would entitle shareholders to an additional $5.00 per share if net sales targets for the drug DIFICID are met for each share of Optimer stock they own. The investigation concerns possible breaches of fiduciary duty and other violations of state law by the Board of Directors of Optimer for not acting in the Company’s shareholders' best interests in connection with the sale process. The transaction may undervalue the Company and will result in a loss for many long term Optimer shareholders. Optimer stock traded at $16.18 per share as recently as May 16, 2013 and traded at $16.43 per share on September 6, 2012. In addition, an analyst has set a $25.00 per share price target on Optimer stock.
