In this paper we establish the existence of solutions for elliptic equations of the form -div(vertical bar del u vertical bar(n-2)del u)+V(x)vertical bar u vertical bar(n-2)u = g(x, u)+lambda h in R-n with n >= 2. Here the potential V(x) can change sign and the nonlinearity g(x, u) is possibly discontinuous and may exhibit exponential growth. The proof relies on the application of a fixed point result and a version of the Trudinger-Moser inequality.
