Bulk article submission and SEO

Question

I have an article with me nicely drafted for the end users.

I have a list of directories that publishes articles.

My question is: if I submit the SAME article in all those directories, will it be considered negatively by the Search Engines? Will I get any benefit from SEO perspective? Or I must write 100 unique articles for 100 different directories to get some points back?

Though the same article published at 100 places may bring some good visitors to my site, but I am concerned about the SE factor. Please suggest.
