AFFILIATED WITH ORTHALLIANCE.


                      ORTHODONTIC CENTERS OF AMERICA, INC.

            INCENTIVE PROGRAMS FOR ORTHALLIANCE ALLIED PRACTITIONERS


         Orthodontic Centers of America, Inc. ("OCA") is a party with
OrthAlliance, Inc. ("OrthAlliance") to an Agreement and Plan of Merger, dated
May 16, 2001 (the "Merger Agreement"), which provides for the merger of one of
OCA's wholly-owned subsidiaries with and into OrthAlliance, with OrthAlliance
becoming a wholly-owned subsidiary of OCA (the "Merger"). Completion of this
proposed Merger is subject to a number of conditions, including approval of the
Merger Agreement by OrthAlliance stockholders. Additional information about this
proposed Merger may be obtained from a Registration Statement on Form S-4, and a
related prospectus/proxy statement, that OCA will file with the Securities and
Exchange Commission in connection with the proposed Merger.

         In connection with the proposed Merger, OCA has implemented the
following six programs under which it may offer shares of its common stock to
certain orthodontists and pediatric dentists who are owners and employees
("OrthAlliance Affiliated Practitioners") of professional entities that are
parties to service, management services, consulting or similar long-term
agreements ("OrthAlliance Service or Consulting Agreements") with OrthAlliance
and its subsidiaries:

         o Stock Pool Program;

         o Target Stock Program;

         o OrthAlliance Stockholder Bonus Program;

         o High Participation Bonus Program;

         o Conversion Incentive Program; and

         o Doctors Trust Program.

         The Stock Pool Program, Target Stock Program, OrthAlliance Stockholder
Bonus Program and High Participation Bonus Program provide incentives to
OrthAlliance Affiliated Practitioners who, along with their respective
professional entities, either (a) amend their respective employment agreement
and OrthAlliance Service or Consulting Agreement as contemplated by Sections 2.4
and 7.2(e) of the Merger Agreement, or (b) enter into OCA's customary form of
business services agreement with OCA or its subsidiaries ("OCA Business Services
Agreement"), in replacement of their existing OrthAlliance Service or Consulting
Agreement, effective as of the proposed Merger with OrthAlliance.

         The Conversion Incentive Program and Doctors Trust Program provide
incentives only to those OrthAlliance Affiliated Practitioners who, along with
their respective professional entities, enter into an OCA Business Services
Agreement effective as of the proposed Merger. Each of these programs would be
conditioned upon, and subject to, completion of the proposed Merger and
compliance with federal and state securities laws.

         The amendments to employment agreements and OrthAlliance Service or
Consulting Agreements contemplated by Sections 2.4 and 7.2(e) of the Merger
Agreement would generally involve the following:

         o AMENDMENT TO EMPLOYMENT AGREEMENT. In the amendment to their
respective employment agreement, the OrthAlliance Affiliated Practitioner and
his or her professional entity would agree to include OrthAlliance as a third
party beneficiary and continue the OrthAlliance Affiliated Practitioner's
employment as an orthodontist or pediatric dentist, as applicable, for a period
of at least three years following the proposed Merger.

         o AMENDMENT TO SERVICE OR CONSULTING AGREEMENT. In the amendment to
their respective OrthAlliance Service or Consulting Agreement, the OrthAlliance
Affiliated Practitioner and his or her professional entity would agree to use
OCA's proprietary computer software and business systems in connection with the
business functions of their practice, maintain the current status of the
advertisement or non-advertisement, as the case may be, of their practice to the
general public, unless OCA otherwise agrees, and continue the OrthAlliance
Affiliated Practitioner's employment as an orthodontist or pediatric dentist, as
applicable, for a period of at least three years following the proposed Merger.

         DATES OF GRANTS; CONDITION TO VESTING. Shares granted under this
program would be issuable in three annual installments, with one-third of the
shares to be issued following each of the first, second and third anniversaries
of the Merger if, during the 12 calendar months immediately preceding that
anniversary, the amount of service or consulting fees paid by the OrthAlliance
Affiliated Practitioner and his or her professional entity to OCA or its
subsidiary is at least 90% of the amount of service or consulting fees they paid
to OrthAlliance or its subsidiary during the 12 calendar months immediately
preceding the Merger.

         PRACTICES WITH MULTI-OWNERS. If an OrthAlliance Affiliated
Practitioner's professional entity is partially owned by one or more other
OrthAlliance Affiliated Practitioners, the number of shares to be granted based
on the amount of service or consulting fees paid would be computed on a pro rata
basis. In addition, the co-owner OrthAlliance Affiliated Practitioners would
have to execute and deliver the applicable amendments to their employment
agreement and OrthAlliance Service or Consulting Agreement, or new OCA Business
Services Agreement, as applicable, by July 27, 2001.

         ELIGIBILITY TO PARTICIPATE. To be eligible to participate in this
program, an OrthAlliance Affiliated Practitioner, along with his or her
professional entity, would have to, by the specified dates, either (1) amend
their existing employment agreement and OrthAlliance Service or Consulting
Agreement, as contemplated by Sections 2.4 and 7.2(e) of the Merger Agreement,
or (2) enter into an OCA Business Services Agreement in replacement of their
existing OrthAlliance Service or Consulting Agreement (effective as of the
Merger). Participation would also require the execution of a written
participation agreement between OCA and the OrthAlliance Affiliated Practitioner
that sets forth, or incorporates by reference, the terms of the program.
Participation in and the grant of any shares under this program would also be
conditioned upon, and subject to, completion of the Merger.

         In addition, to be eligible to participate in this program, an
OrthAlliance Affiliated Practitioner, along with his or her professional entity,
may not be a party to any pending or threatened litigation against OrthAlliance,
OCA or their subsidiaries, nor have given notice of termination or intention to
terminate their respective OrthAlliance Service or Consulting Agreement, and
must be in compliance with their obligation to pay service or consulting fees
under their OrthAlliance Service or Consulting Agreement. If such litigation or
notice has been commenced, threatened or given, it would need to have been
dismissed with prejudice or fully withdrawn in a manner acceptable to OCA.

2.       TARGET STOCK PROGRAM

         Under OCA's Target Stock Program, OCA may grant eligible OrthAlliance
Affiliated Practitioners shares of OCA common stock (except as described below)
as follows:

         NEW OCA AGREEMENT. For OrthAlliance Affiliated Practitioners who, along
with their respective professional entities, enter into an OCA Business Services
Agreement prior to the Merger (which would become effective upon the Merger),
OCA may issue them a number of shares of its common stock equal to:

         (a)      3,

                  TIMES

         (b)      70% OF ASSUMED SERVICE FEES IN PRIOR 12 MONTHS. 70% of the
                  amount of service or consulting fees (excluding any center or
                  other expense reimbursement) that would have been payable to
                  OCA or its subsidiary by the OrthAlliance Affiliated
                  Practitioner or his or her professional entity under the OCA
                  Business Services Agreement during the 12 calendar months
                  immediately preceding the Merger (assuming that the OCA
                  Business Services Agreement had been in effect during that
                  period and also assuming that the operating margin of the
                  practice during that period was 5% higher than the actual
                  operating margin for that period),

                  DIVIDED BY

         (c)      AVERAGE CLOSING PRICE AT THIRD ANNIVERSARY. The average
                  closing price of OCA common stock during the 10 trading days
                  immediately preceding the third anniversary of the Merger,

         IF, during the 12 calendar months immediately preceding the third
         anniversary of the Merger:

                  70% INCREASE IN SERVICE FEES IN YEAR 3. The amount of (A)
                  service or consulting fees (excluding any center or other
                  expense reimbursement) paid to OCA or its subsidiary by the
                  OrthAlliance Affiliated Practitioner or his or her
                  professional entity under the OCA Business Services Agreement,
                  is at least 70% greater than (B) service or consulting fees
                  (excluding any center or other expense reimbursement) that
                  would have been payable to OCA or its subsidiary by the
                  OrthAlliance Affiliated Practitioner or his or her
                  professional entity under the OCA Business Services Agreement
                  during the 12 calendar months immediately preceding the Merger
                  (assuming that the OCA Business Services Agreement had been in
                  effect during that period and also assuming that the operating
                  margin of the practice during that period was 5% higher than
                  the actual operating margin for that period).

         PRO RATA AMOUNT. However, if this 70% target increase in service or
         consulting fees is not achieved during the 12 calendar months
         immediately preceding the third anniversary of the Merger, but the
         amount of service or consulting fees paid during that period is at
         least equal to the amount that would have been paid under the OCA
         Business Services Agreement during the 12 calendar months immediately
         preceding




                                       6
   7

         the Merger (based on the assumptions described above), then OCA may
         grant the OrthAlliance Affiliated Practitioner a pro rata amount of the
         shares of OCA common stock that OCA may have granted if the target
         amount had been achieved. For example, if the amount of service or
         consulting fees increased 35% (i.e., one-half of the targeted increase)
         during that period, then the OrthAlliance Affiliated Practitioner may
         be granted one-half of the number of shares issuable if the target had
         been achieved.

         AMENDMENTS. For OrthAlliance Affiliated Practitioners who, along with
their respective professional entities, amend their respective employment
agreement and OrthAlliance Service or Consulting Agreement prior to the Merger
as contemplated by Sections 2.4 and 7.2(e) of the Merger Agreement, OCA may
issue them a number of shares of OCA common stock equal to:

         (a)      3,

                  TIMES

         (b)      70% OF SERVICE FEES IN PRIOR 12 MONTHS. 70% of the amount of
                  service, consulting or management fees (excluding any center
                  or other expense reimbursement) paid by the OrthAlliance
                  Affiliated Practitioner or his or her professional entity to
                  OrthAlliance or its subsidiaries during the 12 calendar months
                  prior to the Merger,

                  DIVIDED BY

         (c)      AVERAGE CLOSING PRICE AT THIRD ANNIVERSARY. The average
                  closing price of OCA common stock during the 10 trading days
                  immediately preceding the third anniversary of the Merger,

         IF, during the 12 calendar months immediately preceding the third
         anniversary of the Merger:

                  70% INCREASE IN SERVICE FEES IN YEAR 3. The amount of (A)
                  service or consulting fees (excluding any center or other
                  expense reimbursement) paid to OCA or its subsidiary by the
                  OrthAlliance Affiliated Practitioner or his or her
                  professional entity under their OrthAlliance Service or
                  Consulting Agreement is at least 70% greater than (B) service
                  or consulting fees (excluding any center or other expense
                  reimbursement) paid to OrthAlliance or its subsidiary by the
                  OrthAlliance Affiliated Practitioner or his or her
                  professional entity under their OrthAlliance Service or
                  Consulting Agreement during the 12 calendar months immediately
                  preceding the Merger.

         PRO RATA AMOUNT. However, if this 70% target amount of increased
         service or consulting fees is not achieved during the 12 calendar
         months immediately preceding the third anniversary of the Merger, but
         the amount of service or consulting fees paid during that period is at
         least equal to the amount paid during the 12 calendar months
         immediately preceding the Merger, then OCA may grant the OrthAlliance
         Affiliated Practitioner a pro rata amount of the shares of OCA common
         stock that OCA may have granted if the target amount had been achieved.
         For example, if the amount of service or consulting fees increased 35%
         (i.e., one-half of the targeted increase) during that period, then the
         OrthAlliance Affiliated Practitioner may be granted one-half of the
         number of shares issuable if the target had been achieved.



                                       7
   8


         OCA MAY CHOOSE TO SUBSTITUTE INTEREST BEARING NOTE. OCA could elect, in
its sole discretion, to issue the OrthAlliance Affiliated Practitioner a
promissory note in an amount equal to that computed as described above, which
would be payable over 5 years and bear interest at the prime rate plus 1.5% per
year, in lieu of shares of OCA common stock. Payments under the note would be
subject to the same condition described in the following paragraph with respect
to issuance of shares of OCA common stock.

         DATES OF GRANTS; CONDITION TO VESTING. Shares granted under this
program would be issuable in four annual installments, with one-fourth of the
shares to be issued following each of the fifth, sixth, seventh and eighth
anniversaries of the Merger if, during the 12 calendar months prior to that
anniversary, the amount of service or consulting fees paid by the OrthAlliance
Affiliated Practitioner and his or her professional entity to OCA or its
subsidiary is at least 90% of the amount of service or consulting fees they paid
to OrthAlliance or its subsidiary during the 12 calendar months prior to the
Merger.

         PRACTICES WITH MULTI-OWNERS. If an OrthAlliance Affiliated
Practitioner's professional entity is partially owned by one or more other
OrthAlliance Affiliated Practitioners, these amounts would be computed on a pro
rata basis. In addition, the co-owner OrthAlliance Affiliated Practitioners
would have to execute and deliver the applicable amendments to their employment
agreement and OrthAlliance Service or Consulting Agreement, or new OCA Business
Services Agreement, as applicable, prior to the Merger.

         ELIGIBILITY TO PARTICIPATE. To be eligible to participate in this
program, an OrthAlliance Affiliated Practitioner, along with his or her
professional entity, prior to the Merger would have to either (1) amend their
existing employment agreement and OrthAlliance Service or Consulting Agreement,
as contemplated by Sections 2.4 and 7.2(e) of the Merger Agreement, or (2) enter
into an OCA Business Services Agreement in replacement of their existing
OrthAlliance Service or Consulting Agreement (effective as of the Merger).
Participation would also require the execution of a written participation
agreement between OCA and the OrthAlliance Affiliated Practitioner that sets
forth, or incorporates by reference, the terms of the program. Participation in
and the grant of any shares under this program would also be conditioned upon,
and subject to, completion of the Merger.

         In addition, to be eligible to participate in this program, an
OrthAlliance Affiliated Practitioner, along with his or her professional entity,
may not be a party to any pending or threatened litigation against OrthAlliance,
OCA or their subsidiaries, nor have given notice of termination or intention to
terminate their respective OrthAlliance Service or Consulting Agreement, and
must be in compliance with their obligation to pay service or consulting fees
under their OrthAlliance Service or Consulting Agreement. If such litigation or
notice has been commenced, threatened or given, it would need to have been
dismissed with prejudice or fully withdrawn in a manner acceptable to OCA.

         In addition, to be eligible to participate in this program, an
OrthAlliance Affiliated Practitioner, along with his or her professional entity,
may not be a party to any practice improvement performance guarantee agreement
with OrthAlliance or its subsidiary.

         DUE DILIGENCE TO DETERMINE OPERATING MARGIN. To permit OCA to determine
the appropriate operating margin for computing the number of shares to be
granted under this program with respect to a new OCA Business Services
Agreement, the OrthAlliance Affiliated Practitioner would provide OCA with
financial information OCA reasonably requests about his or her practice.

                           her professional entity under the OCA Business
                           Services Agreement during the 12 calendar months
                           immediately preceding the Merger (assuming that the
                           OCA Business Services Agreement had been in effect
                           during that period and also assuming that the
                           operating margin of the practice during that period

2.       DOCTORS TRUST PROGRAM

         Under OCA's Doctors Trust Program, for eligible OrthAlliance Affiliated
         Practitioners:

         TWO YEAR OPTION TO PURCHASE SHARES. At anytime during the two years
immediately following the Merger, the OrthAlliance Affiliated Practitioner could
elect, by giving OCA written notice, to purchase a number of shares of OCA
common stock equal to (A) $60,000, divided by (B) the average closing sales
price per share of OCA common stock reported for the 10 trading days immediately
prior to the Merger.

         INSTALLMENT PAYMENTS OF PURCHASE PRICE. The purchase price of the
shares would equal $40,000 and would be payable by the OrthAlliance Affiliated
Practitioner in 40 equal quarterly installments of $1,000 each over a period of
10 years, beginning on the second anniversary of the Merger.

         RESTRICTIONS ON TRANSFER. These shares would be subject to contractual
restrictions on transfer. No shares could be sold or transferred prior to the
eleventh anniversary of the Merger. Beginning on that eleventh anniversary,
one-seventh of the shares would become eligible for sale or transfer during each
of the following seven years.

         FORFEITURE OF SHARES. Shares that are not then granted or eligible for
sale or transfer would be forfeited if the OrthAlliance Affiliated Practitioner:

         (a)      Ceases to be employed full-time as an orthodontist or
                  pediatric dentist, as applicable, in his or her respective
                  practice prior to the tenth anniversary of the Merger, or

         (b)      Ceases to own an equity interest in the professional entity
                  that is a party to the OCA Business Services Agreement prior
                  to the tenth anniversary of the Merger, or

         (c)      And his or her professional entity's OCA Business Services
                  Agreement terminates, or

         (d)      Or his or her professional entity fails to utilize OCA's
                  proprietary computer software and business systems in
                  connection with the business functions of their practice, or

         (e)      Or his or her professional entity fails to comply with OCA's
                  policies, procedures and systems, including a productive
                  working relationship with OCA's corporate office staff and
                  other orthodontists and dental professionals who are
                  affiliated with OCA, fulfil his or her financial obligations
                  to OCA or its subsidiaries, or breaches his or her OCA
                  Business Services Agreement.

         NO RETURN OF PURCHASE PRICE. If shares acquired under this program are
forfeited, any purchase price previously paid would not be returned, but further
obligations to pay the quarterly installments would be canceled.

         DEATH OR DISABILITY. If the OrthAlliance Affiliated Practitioner dies
or becomes permanently disabled (and ceases to practice orthodontics or
pediatric dentistry, as applicable), a proportionate number of shares for which
quarterly installments of purchase price had then been paid (that is,
one-fortieth of the number of shares for each quarterly installment of purchase
price that had been paid) would not be forfeited due to those events, and
one-seventh of that proportionate amount would become eligible for sale or
transfer during each of the following seven years.

   19

         TRANSFER OF PRACTICE AFTER 10 YEARS. If the OrthAlliance Affiliated
Practitioner remains employed full-time as an orthodontist or pediatric dentist,
as applicable, in his or her respective practice, owns an equity interest in the
professional entity that is a party to the OCA Business Services Agreement,
remains a party to an OCA Business Services Agreement and otherwise complies
with the terms and conditions of this program through the tenth anniversary of
the Merger, then the OrthAlliance Affiliated Practitioner could thereafter
transfer his practice to another orthodontist or pediatric dentist, as
applicable, acceptable to OCA who assumes all of the OrthAlliance Affiliated
Practitioner's obligations under the OCA Business Services Agreement and,
subject to continued compliance with his or her covenant not to compete, a
proportionate number of shares for which quarterly installments of purchase
price had then been paid would not be forfeited due to those events, and
one-seventh of that proportionate amount would become eligible for sale or
transfer during each of the following seven years.

         ELIGIBILITY TO PARTICIPATE. To be eligible to participate in this
program, an OrthAlliance Affiliated Practitioner, along with his or her
professional entity, would have to, prior to the Merger, enter into an OCA
Business Services Agreement in replacement of their existing OrthAlliance
Service or Consulting Agreement (effective as of the Merger). Participation
would also require the execution of a written participation agreement between
OCA and the OrthAlliance Affiliated Practitioner that sets forth, or
incorporates by reference, the terms of the program. Participation in and
purchase of shares under this program would also be conditioned upon, and
subject to, completion of the Merger.

         In addition, to be eligible to participate in this program, an
OrthAlliance Affiliated Practitioner, along with his or her professional entity,
may not be a party to any pending or threatened litigation against or involving
OrthAlliance, OCA or their subsidiaries, nor have given notice of termination or
intention to terminate their respective OrthAlliance Service or Consulting
Agreement, and must be in compliance with their obligation to pay service or
consulting fees under their OrthAlliance Service or Consulting Agreement. If
such litigation or notice has been commenced, threatened or given, it would need
to have been dismissed with prejudice or fully withdrawn in a manner acceptable
to OCA.

         PRACTICES WITH MULTI-OWNERS. If an OrthAlliance Affiliated
Practitioner's professional entity is partially owned by one or more other
OrthAlliance Affiliated Practitioners, the co-owner OrthAlliance Affiliated
Practitioners would have to execute and deliver the new OCA Business Services
Agreement prior to the Merger.

         ISSUANCE TO PROFESSIONAL CORPORATION. Shares of OCA common stock
issued under this program may be issued to the participant's professional
corporation or other entity, rather than to the individual participant. If the
professional corporation is conveyed to a successor practitioner in accordance
with the applicable OCA Business Services Agreement, the shares of OCA common
stock would not be forfeited due to that event, but rather would continue as an
asset of the professional corporation under the ownership of the successor
practitioner. For purposes of the minimum number of years of full-time
employment and ownership of the professional corporation required under this
program, the successor would be credited with those of the original owner of
the professional corporation.
