ROCKVILLE, Md., Aug 4, 2008 (PrimeNewswire via COMTEX) ----Nabi Biopharmaceuticals (Nasdaq:NABI) announced today a settlement of an arbitration proceeding against Inhibitex, Inc., effective August 1, 2008. Under the terms of the settlement, Inhibitex agreed to pay Nabi a total of $2.2 million, $1.7 million in connection with the execution of settlement and $0.5 million by October 15, 2008 with 5% interest from August 1, 2008.

In 2006, Nabi recorded $4.5 million of other biopharmaceutical revenue for contract manufacturing, consisting of $1.2 million for product manufactured under a manufacturing agreement with Inhibitex., Inc and $3.3 million for penalties recorded in conjunction with the termination of the agreement. Inhibitex disputed the amounts due. Nabi arbitrated this dispute and, in early 2007, received a favorable ruling from the arbitrator awarding the full $4.5 million. Subsequently, Nabi moved to confirm the award in the Supreme Court of New York and Inhibitex moved to vacate the award. In late 2007, the court issued a decision denying Nabi's petition with respect to $3.3 million in cancellation fees, but affirmed the arbitrator's award in the amount of $1.2 million which was received in January 2008. Nabi filed an appeal in February 2008 with respect to the portion of the decision vacating the $3.3 million portion of the award. This settlement effectively terminates the appeal process.

"We are pleased to reach this settlement which will result in the payment to Nabi of most of the disputed amount and the end of future costs associated with our appeal," stated Dr. Raafat Fahim, President and Chief Executive Officer of Nabi Biopharmaceuticals.
