Adverse Changes In The Financial Condition Of Our Joint Venture Partner, TPL, Could Have A Significant And Adverse Effect On Us.

While we are not privy to the financial condition of our joint venture partner, TPL, several factors could have a negative effect on TPL’s financial condition, such as the continued decline in MMP Portfolio license revenue and increased MMP Portfolio related litigation costs. Additionally, the adverse outcome of known current contract litigation against TPL and other factors to which we are not privy while not impacting us directly, may impact us indirectly to the extent the licensing program is negatively affected. In the event that one or more of the foregoing adversely affects TPL’s financial condition, TPL’s ability to continue to aggressively pursue the licensing of the MMP Portfolio on behalf of PDS could be severely impacted which would in turn adversely affect our revenue and cash flow.
