                 ORTHODONTIC CENTERS OF AMERICA AND ORTHALLIANCE
                  ANNOUNCE STATUS OF MERGER RELATED AMENDMENTS

         METAIRIE, Louisiana (June 28, 2001) - Orthodontic Centers of America,
Inc. (NYSE: OCA) and OrthAlliance, Inc. (NASDAQ/NM: ORAL) announced today that
they have received signed amendments to the employment agreements and service or
consulting agreements of OrthAlliance affiliated professionals representing more
than the minimum threshold amounts specified as a condition to OCA's obligation
to close its proposed merger with OrthAlliance. As previously announced, OCA and
OrthAlliance entered into a definitive merger agreement on May 16, 2001, whereby
a wholly-owned subsidiary of OCA would merge into OrthAlliance in a
stock-for-stock transaction, with OrthAlliance becoming a wholly-owned
subsidiary of OCA.

         Under the terms of the merger agreement, OCA's obligation to complete
the merger is conditioned upon, among other things, at least 56 of 184
designated OrthAlliance affiliated professionals, and a number of those
OrthAlliance affiliated professionals representing at least 30% of
OrthAlliance's annual service fees, amending their respective employment
agreement and OrthAlliance service or consulting agreement on terms specified in
the merger agreement. Completion of the proposed merger is subject to a number
of other conditions, including approval by stockholders of OrthAlliance. The
merger is anticipated to close in the third quarter of 2001 and to be accounted
for as a purchase.

         W. Dennis Summers, Chairman of the Board and interim President and
Chief Executive Officer of OrthAlliance, said, "We are not surprised to have
received so many amendments this quickly, and we expect to continue the brisk
pace of OrthAlliance allied professionals willing to amend their applicable
agreements in accordance with terms described in the merger agreement.
Increasingly, these professionals are recognizing the wisdom in receiving the
full suite of OCA's powerful package of business services as a clear, proven
vehicle for practice growth."
