Feel free to call us at the telephone numbers listed at the end of this letter. General We note the representations in your January 12, 2005, response to our prior comment that the agreement with Nycomed has been terminated; all rights to market and sell Oxygent in Iran and Syria have reverted back to PFC; and Nycomed conducted no commercial activities related to Oxygent in either Iran or Syria prior to termination of the agreement. Please advise us whether PFC has any plans or intentions to sell Oxygent in Iran and /or Syria. Please briefly describe any such plans or intentions, and give us your view as to their materiality to the Company, and whether they constitute a material investment risk to Company security holders, in light of the fact that those countries have been designated state sponsors of terrorism by the U.S. State Department, and are subject to economic sanction administered by the U.S. Treasury Department`s Office of Foreign Assets Control.
