We detect [O III] emission from a \"low-cool\" DLA at z_abs = 2.9791 (having log N(HI)=21.69+\\-0.10, [Zn/H] = -1.83+\\-0.18) at an impact parameter of, $\\rho$ ~12 kpc. The associated galaxy is compact with a dynamical mass of (1-6)x10^9 M_solar, very high excitation ([O III]/[O II] and [O III]/[H$\\beta$] both greater than 10), 12+[O/H]<=8.5 and moderate star formation rate (SFR <=2 M_solar yr^{-1}).
