Exudate of neutrophils and fibrin with dying RBCs describes which pneumonia stage?

In lobar pneumonia, the gray hepatization stage is defined by alveolar spaces filled with a fibrinopurulent exudate and neutrophils, while the red blood cells have been destroyed. The breakdown of RBCs gives the lung a grayish appearance, hence the name gray hepatization. This stage comes after the red hepatization phase, which has a red appearance from intact RBCs, and before resolution, when macrophages clear the exudate. So the description—exudate of neutrophils and fibrin with dying RBCs—fits gray hepatization exactly.
