                                    EXHIBIT A

         On March 19, 2001, the Registrant announced that it had defaulted on
its obligation to pay an approximately $4.4 million interest payment on its 4.5%
Convertible Subordinated Debentures due 2003 (the "Notes"). The default resulted
in a corresponding default under the Registrant's bank credit facility. In
addition, any acceleration of the Notes will cause a default under the Series A
Zero Coupon Convertible Subordinated Notes due 2014 held by affiliates of
Warburg, Pincus & Co. (the "Warburg Notes"). The Registrant has obtained limited
forbearance agreements from a majority of the holders of the Notes and Warburg
Pincus & Co., subject to certain conditions, and is seeking a waiver from its
senior lenders of the default under the credit facility. Because the Registrant
is still in the process of analyzing the potential ramifications of these
various defaults, and because of the decreased staffing levels of the Registrant
resulting from its current financial condition, the Registrant has been unable
to complete its Annual Report on Form 10-K for the year ended December 31, 2000
within the prescribed period without unreasonable effort or expense. The
Registrant expects to be able to complete its Annual Report on Form 10-K for the
year ended December 31, 2000 no later than April 17, 2001.

                                    EXHIBIT B

         The financial statements for the year ended December 31, 2000 will
reflect the effect of the charges to earnings incurred by the Registrant
throughout 2000 related primarily to the write-off of assets in the
multi-specialty clinic management and IPA management divisions, the effect of
the sale of the majority of the Registrant's assets related to its
multi-specialty management division, and the effect of the Registrant's defaults
under the Notes and its bank credit facility and the possible default under the
Warburg Notes. Because the Registrant is still in the process of analyzing the
potential ramifications of these various defaults, and because of the decreased
staffing levels of the Registrant resulting from its current financial
condition, the Registrant has been unable to complete its Annual Report on Form
10-K for the year ended December 31, 2000 within the prescribed period without
unreasonable effort or expense.
