                Pediatrix Provides Update on Stock Option Review

    Announces Closing of FTC Investigation, With No Action Taken On
                 Pediatrix's 2001 Magella Acquisition



    FORT LAUDERDALE, Fla.--(BUSINESS WIRE)--Dec. 6, 2006--Pediatrix
Medical Group, Inc. (NYSE:PDX) today announced an update with respect
to its previously disclosed internal voluntary review of its
historical stock option practices and the closing by the Federal Trade
Commission of its investigation of the Company's 2001 acquisition of
Magella Healthcare Corporation.

    Stock Option Review

    The Company's review of its historical stock option practices is
being conducted by Pediatrix's Audit Committee with the assistance of
independent outside legal counsel and forensic accountants and with
the full cooperation of the Company's management. The review covers
all stock options granted from the date of the Company's initial
public offering in 1995 through the year to date in 2006. Although the
Committee has not completed its work or reached final conclusions, on
December 5, 2006, the Company's Board of Directors received a
preliminary oral status report from the Committee regarding its
activities to date. Among other things, this report noted that, based
on evidence reviewed to date, the Committee expects to conclude that
there were deficiencies in the process by which options were granted
at the Company, including instances of backdating of option grants as
well as inadequate procedures which resulted in or permitted the
misdating of option grants.

    The Audit Committee also reported that it has not yet completed
its analysis of the financial impact of the improper dating of the
Company's stock options, including possible equity compensation
charges to the Company's income statements and related tax effects.
The Committee told the Board, however, that its tentative calculations
indicate that the Company may have to recognize additional
compensation expense of approximately $28 million, in the aggregate,
on a pre-tax basis for the 1995 through 2006 period. The Audit
Committee emphasized, however, that this amount reflects preliminary
consideration of appropriate financial reporting measurement dates for
improperly dated stock options and, accordingly, these amounts are
subject to further review and could change significantly. Moreover,
this estimate and the underlying analysis of the stock option grants
have not yet been reviewed by the Company's independent public
accountants or the Company's management. The Company has also not yet
determined whether any restatement of the Company's historical
financial statements will be required.

    The Company also announced that Lawrence M. Mullen has resigned
from Pediatrix's Board of Directors following the Audit Committee's
preliminary report. Mr. Mullen, a member of the Audit Committee,
recused himself from its independent stock option review. During his
tenure as Chief Financial Officer of the Company from 1995 to 1998,
Chief Operating Officer from August, 1998 to May, 2000 and thereafter
as a Vice President in charge of special projects until his retirement
in April, 2001, Mr. Mullen had a significant role in the
administration of the Company's stock option program and practices. To
fill the vacancy on the Audit Committee created by Mr. Mullen's
resignation, the Board of Directors has appointed Waldemar A.
Carlo, M.D., a Director of the Company since June 1999.

    The Company voluntarily contacted the staff of the Securities and
Exchange Commission regarding the Committee review and is cooperating
with an informal investigation by the staff regarding this matter. The
Committee is working to complete its review and to take or recommend
appropriate remedial measures, including enhanced stock option
granting procedures, as soon as possible.

    FTC Investigation Completed

    Pediatrix also announced that it has been notified that the
Federal Trade Commission has closed its investigation of Pediatrix's
2001 acquisition of Magella Healthcare Corporation with a finding that
no further action is warranted by the Commission. The FTC had
initiated a retrospective review of the Magella acquisition in June
2002.
