Item 2.  Acquisition or Disposition of Assets

         On February 28, 1998, Gentle Dental Service Corporation (the "Company")
completed the acquisition of substantially all of the assets of Affordable
Dental Care, Inc. ("ADC"), a provider of dental care in western Oregon. The ADC
operations have 19 dentists in 9 offices in the Willamette Valley and
southwestern Oregon. All of ADC's offices are outside of the Portland
metropolitan area, where the Company currently provides dental practice
management services to 13 offices. In addition, the Company has entered into a
definitive agreement to acquire all of the outstanding stock of Managed Dental
Care of Oregon, Inc. ("MDCO"), a dental care organization which has an annually
renewable contract with the state of Oregon to provide care under the Oregon
Health Plan. MDCO in turn contracts with dental care providers, including ADC,
to provide dental care to Oregon Health Plan participants. The acquisition of
MDCO is subject to Oregon State regulatory approval.

         The purchase price paid at closing for ADC's assets consisted of
$7,574,600 in cash. The purchase price to be paid at closing for the stock of
MDCO will consist of $950,000 in cash. In addition, the Company has agreed to
make cash earnout payments equal to .66 times the combined EBITDA of the
acquired businesses for the first 12 months following the ADC closing, .67 times
such EBITDA for the second 12 months following the ADC closing, and .67 times
such EBITDA for the third 12 months following the ADC closing. The cash paid at
closing was borrowed under the Company's credit facility with Imperial Bank.
