MBF Healthcare Acquisition Corp. (AMEX: MBH) has again revised the terms of its pending buyout of Critical Homecare Solutions Holdings Inc., which it originally agreed to acquire from Kohlberg & Co. back in February. The original cut was from $534 million to $479 million, and came after a financing commitment letter from Jefferies Finance expired on July 31. Now, MBF said in an SEC filing that the cash paid at closing will be reduced by another $12 million. It also has made additional alterations, including the sale of new unregistered shares to the sellers. www.criticalhs.com
