Route Notes	The summit team of Martine Bakker, Ronald Naar, Mark Van den Berg along with Kaji, Nuru Jangbu and Pasang departed C3 (7500m) on 21 May. Naar, Van den Berg and Kaji reached 7830m with Martine and Nuru Jangbu slightly back at 7800m. At 4:30 pm after 8 hours of climbing, they decided to turn back due to the lateness of the day; the weather also was deteriorating. The next day 22 May the team descended down. Since Naar did not feel well, he and Kaji started down immediately ahead of the other members towards C1. But at around 6800m Naar collapsed and died of apparent altitude sickness. Bert De Jong, Klaas Klein, Remco Loewensteyn, Annette Meesters and Ben Verbree left the expedition early due to various illnesses and/or fatique. The leader Jan Midde managed the expedition from ABC.
