**One graduate research assistant for two years.

**$2,000 for software to analyze data

**$12,000 for hardware (i.e., special computer processor and other equipment)

**A nine-month salary at the 25th percentile.  However, For every high-quality refereed journal article, I will give you a bonus equivalent to +10 percentile, and for each conference presentation, I will give you a bonus equivalent to +3 percentile.   Your minimum salary will be the 25th percentile, but you can max out at the 98th percentile.

**Required to teach two summer sessions, none of which count toward your teaching load

**Three-day-a-week teaching schedule.

Welcome to our university!"

Critique: 

What techniques did you use to reach this agreement? 

What techniques did the dean use? 

You got above-average outcomes for software and hardware and you got a graduate student research assistant for more than one year.  The "salary + bonus" system will give you the opportunity to maximize your income, but it will require a lot of "output" for you to do that.  Perhaps you want to try again to see if you can get a better deal.
