Rigrodsky & Long, P.A. announces that it is investigating potential claims against the board of directors of Adolor Corporation (“Adolor” or the “Company”) (Nasdaq: ADLR) concerning possible breaches of fiduciary duty and other violations of law related to the Company’s entry into an agreement to be acquired by Cubist Pharmaceuticals, Inc. (“Cubist”) in a transaction with an approximate value up to $415 million.

Under the proposed agreement, Cubist will acquire all of the outstanding shares of Adolor for $4.25 per share in cash, or approximately $190 million on a fully-diluted basis, net of Adolor’s third quarter 2011 cash balance.  In addition to the upfront cash payment, each Adolor stockholder will receive one Contingent Payment Right (“CPR”), entitling the holder to receive additional cash payments of up to $4.50 for each share they own if certain regulatory approvals and/or commercialization milestones for ADL5945 are achieved.  The total transaction is valued at up to $415 million, net of Adolor’s third quarter 2011 cash balance.  Under the proposed agreement, Cubist will commence a tender offer to purchase all of the outstanding shares of Adolor for the upfront cash payment and a CPR.

The investigation concerns whether Adolor’s board of directors adequately shopped the Company to obtain the best price possible for Adolor’s shareholders before entering into the agreement with Cubist.  Indeed, according to Yahoo! Finance, at least one analyst has set an $8.00 per share stock price for Adolor stock.
