Business Wire, March 20, 2007

EL SEGUNDO, Calif. -- InterDent Service Corporation announced today that it has entered into a First Supplemental Indenture, dated as of March 19, 2007, relating to its 10th% Senior Secured Notes due 2011. As previously disclosed in a press release issued by the Company on March 16, 2007, among other things, the First Supplemental Indenture eliminated the requirement that the Company file reports with the Securities and Exchange Commission. Consequently, the Company filed a Form 15 with the Securities and Exchange Commission today to deregister the Notes and terminate its duty to file reports under Section 15(d) of the Securities Exchange Act of 1934.

In connection with the approval and adoption of the First Supplemental Indenture, the Company will pay to each record holder of its Notes as of March 16, 2007, a one-time fee of one-half of one percent (0.5%) of the outstanding principal amount of the Notes held by such holder.
