     Net revenues for the second quarter ended June 30, 2001, increased 5.9% to
$38.2 million compared with $36.1 million reported for the same period in the
prior year period. Net income for the second quarter of 2001 totaled $1.4
million compared with net income of $2.7 million for the second quarter ended
June 30, 2000. Second quarter results included approximately $1.6 million of
costs associated with the Company's strategic alternatives project primarily
related to costs of advisers, legal and professional and other
transaction-related expenses. Earnings per share (diluted) for the second
quarter of 2001 were $0.11 compared with earnings per share (diluted) of $0.21
for the same period in 2000. In addition, the Company's comparative
same-practice growth approximated 6.3% for the second quarter ended June 30,
2001.

     Net revenues for the six months ended June 30, 2001, increased 16.0% to
$76.8 million compared with $66.2 million reported for the same period in the
prior year period. Net income for the six-month period ended June 30, 2001,
totaled $3.2 million compared with net income of $5.3 million for the six months
ended June 30, 2000. Earnings per share (diluted) for the first half of 2001
were $0.26 compared with earnings per share (diluted) of $0.41 for the same
period in 2000.

     As of June 30, 2001, the Company had affiliations with 226 practitioners
operating out of 397 offices in 32 states. Annual patient revenues at
acquisition and before internal growth approximate $192.2 million.

     On May 16, 2001, OrthAlliance entered into a definitive merger agreement
with Orthodontic Centers of America , Inc. (NYSE:OCA). OCA is a leading provider
of integrated business services to orthodontic practices. As of June 30, 2001,
OCA was affiliated with over 400 orthodontists treating over 350,000 patients in
over 600 orthodontic centers throughout the United States and in Japan, Mexico
and Spain. Under the terms of the agreement, a wholly owned subsidiary of OCA
would merger into OrthAlliance in a stock-for-stock transaction, with
OrthAlliance becoming a wholly owned subsidiary of OCA. OrthAlliance and OCA
also subsequently announced that the Company had received signed amendments to
the employment agreements and service or consulting agreements of its affiliated
professionals representing more than the minimum threshold amounts specified as
a condition to OCA's obligation to close the proposed merger with OrthAlliance.
The closing is also subject to approval by OrthAlliance stockholders and other
conditions.

     W. Dennis Summers, chairman of the board of OrthAlliance and interim
president and chief executive officer of the Company, said, "We are pleased to
report that we were able to sustain solid financial performance in the second
quarter - especially in the midst of the transition we are making as a company.
Our progress in the pending merger between OrthAlliance and Orthodontic Centers
of America, Inc. (OCA) is on track. OCA and OrthAlliance recently announced that
OrthAlliance had received from its affiliates more than the minimum number of
signed amendments to employment and service or consulting agreements specified
as a condition to the merger agreement. With this condition met, and
anticipating approval by OrthAlliance shareholders, we currently anticipate the
transaction to close over the next several months. We continue to believe that
this merger is in the best interests of OrthAlliance shareholders, as evidenced
by the strong second quarter results recently announced


                                     -MORE-
