Interpretation of interaction effect in negative binomial regression

I am trying to interpret my interaction effects, which are all negative. One example: Experience (variable A) x absolute size of the acquired knowledge base (variable B): B= -0.002, exp(B)= 0.998.

Can I interpret this interaction in the following way: As variable B decreases, the effect of A increases. How can this interaction be interpreted in terms of exp(B)?

When variable A increases by one unit the effect of variable B decreases by a factor .998 or $(.998-1)\times 100\% = -.2\%$.
