First want to clarify that the note covenants use EBIDTA not cash EBIDTA. Second, I took a look at what will happen to trailing 12 month EBIDTA going forward using Seitel's guidance of an improvement in Q2 (given Apr 01) and through the rest of the year. Looking back at revenue per quarter for 2001, Q1 and Q4 were the highest at about $38 million each. This leaves 60 million of revenue contribution from Q2 and Q3. Assuming that this is split 50/50 by quarter you get a 30 million revenue number per quarter. If you buy into the guidance provided by the company, trailing 12 month EBIDTA shouldn't decrease significantly when Q2 02 is included.
