Position of singularities and fundamental group of the complement of a union of lines

In this paper we give two examples of complex line arrangements in CP2 with 7 lines, that both have 3 triple points and 12 double points, and their complements have nonisomorphic global fundamental groups. These two line arrangements are, in some sense, a much simpler example of a pair of plane algebraic curves that have the same local topology but have complements with different global topology-compare with the example given by Zariski, or the recent example given by Artal-Bartolo.
