Looks like the deal happened @ April 5th, 2012 for $1.82 in cash and one Contingent Value Right (CVR) per share, given certain criteria were met. Spectrum bought them for $206 million.

In Oct. 2011 prior to the Spectrum deal, another deal was stuck with AMAG Pharmaceuticals to buy Allos for $195 million and $2.44 per share. Shareholders sued, and Allos settled, forgoing the deal which opened the doors for Spectrum.
