Simply, economic definitions aside, euribor is calculated as such: 100 - interest rate = 3 month euriobor price. So, if front month 3 mth euribor (March 08) is quoted as 95.670 it implies that the implied interest rate for March 08 is 100 - 95.670 = 4.33%
Obviously there are further out months quoted, so you get the implied rate for the curve. In a nutshell, Interest rate down, euribor up and vice versa.
