A developer seeking to build student housing on former Interstate-195 land in Providence has a clause that would allow them to back out on the deal.  Texas-based Friendship and Clifford can withdraw from the project if they are unable to reach a deal with the city on tax breaks.  The developer is seeking a 12-year tax abatement agreement, which is the standard term for this type of project.  The sides have until March 1st to finalize the deal.
