Order of Court.

After plenary consideration of this matter, it is found not to satisfy the criteria for the grant of certiorari and the writ is therefore vacated.

dissenting.

I think the agreement in this case is not valid. For other reasons see Smith, J., dissenting in Shankman v. Coastal

Psychiatric Assoc., 258 Ga. 294 (368 SE2d 753) (1988).
