We present the results of X-ray spectral analysis of the superbubble (SB) around the OB association LH9 in the H II complex N11 in the Large Magellanic Cloud. Using observations from Suzaku, we have modeled the X-ray emission over the energy range 0.2-7.5 keV. We constrained the thermal spectrum below 2 keV using a thermal plasma model found in a previous XMM-Newton study of the N11 region. We find that the hard X-ray emission (>2 keV) requires a nonthermal power-law component. The photon index of this component was found to be Γ = 1.72±0.15. We performed an energy budget analysis for N11 using the known stellar content of LH9. We found that the observed thermal and kinetic energy in the SB is only half of the expected mechanical energy injected by stars.
