Existence of Extremal Metrics on Almost Homogeneous Manifolds of Cohomogeneity One---III, International Journal of Mathematics, vol 14 (2003), 259--287. The final version before publication Note written on Feb. 14, 2007: The original paper was cut by the referees and the editors. Therefore, some information in the paper was missing. Here I found a pdf copy of an original source which was modified after receiving two preprints from Andrew Spiro and further discussions. It is apparently that the completion of the normal bundle of the exceptional divisor in section 6 is different from the projective normal bundle and our degeneration (if it actually exists) is a little different from that in the recent paper of J. Ross and R. P. Thomas (JDG 72 (2006), 429--466). Our condition is stronger than theirs.
