Permits have been obtained for 18 of the 28 wells currently proposed to be drilled in the Marcellus Shale primary area, which are disclosed in Appendix A - Information Regarding Currently Proposed Prospects for Atlas Resources Public #18-2008(A) L.P. in the prospectus. With respect to the other 10 wells that are proposed, permits for seven of the wells are currently in the application process and three wells are staked - in process, which is required before filing the drilling application. It has been the managing general partner’s recent experience that once an application is filed, it takes approximately 45 days to receive the permit. More importantly, drilling permits have been obtained for 32 additional wells in the Marcellus Shale area from which the managing general partner can choose well locations for the partnerships.
