I underdeveloped a 120 roll of Neopan 400 in PMK by about 2 minutes or so. Is there any way to intensify such a negative perhaps using selenium toner?

Selenium works great as an intensifier. You'll gain about 1 grade of contrast, without any increase in grain or loss of sharpness.

Dilute it 1:2 with distilled water. Process the film in the solution for 10 minutes using standard 10sec/min agitation. Wash it normally, 5-10 minutes.

John, take a look at David Vestal's book, The Craft of Photography. He talks about Kodak Chromium Intensifier as giving a wide intensification latitude. You bleach the film and then redevelop it in the light, taking it out a bit before it reaches a good density. I'm dying to see how well this works. But for all I know, this technique may be way outdated- the book was written in the 70's.
