I worked for RSA back in the 1990s. Back then at least, the sales staff's pay was based heavily on commission. It has a sliding structure that meant that people who sold more got a higher percentage. $10m might not have been a lot to EMC, but to the sales guy it probably meant over $50k, maybe over $100k. That one sale alone would have blasted him/her past the quota and bumped up the commission percentage.
