("Progenics") of the Company's 50% ownership interest in PSMA Development Company LLC (the "Joint Venture"). On April 20, 2006, the Company entered into a Membership Interest Purchase Agreement with Progenics providing for the sale to Progenics of the Company's 50% ownership interest in the Joint Venture. In addition, the Company entered into an Amended and Restated PSMA/PSMP License Agreement with Progenics and the Joint Venture pursuant to which the Company licensed the Joint Venture certain rights in PSMA technology. Under the terms of such agreements, the Company sold its 50% interest in the Joint Venture for an upfront cash payment of $13.2 million, potential future milestone payments totaling up to $52 million payable upon regulatory approval and commercialization of the Joint Venture products, and an undisclosed royalty on future product sales of the Joint Venture. The following selected unaudited pro forma balance sheet information of the Company reflects the disposition of the Joint Venture as if it had occurred on December 31, 2005. The accompanying unaudited pro forma statement of operations information for the year December 31, 2005 reflects the disposition of the Joint Venture as if the sale had occurred on January 1, 2005. The pro forma adjustments are based on the operations of the Joint Venture during the period presented and the impact from the sale of the Joint Venture. Consequently, the pro forma financial information presented is not necessarily indicative of the results that would have been reported had the transactions actually occurred on the date specified. The pro forma adjustments do not include any gain the Company may record in connection with this transaction. The pro forma adjustments for the years ended December 31, 2005 from the sale of the Company's 50% ownership interest in the Joint Venture would have reduced license and contract revenue by $185,000, equity in loss of Joint Venture by $3.2 million, and operating loss by $3.0 million, or $0.18 per basic and diluted share. In addition, the pro forma adjustments as of December 31, 2005 from the sale of the Company's 50% ownership interest in the Joint Venture would have increased cash and cash equivalents by $13.2 million, reduced other assets by $379,000 and reduced accumulated deficit by $12.8 million.
