Subject Company: Orthodontic Centers of America, Inc. Commission File No.: 1-13457 THE FOLLOWING ARE MATERIALS USED IN A PRESENTATION TO PRACTITIONERS 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. 2 PLEASE NOTE THAT THIS DOES NOT CONSTITUTE AN OFFER OF ANY SECURITIES FOR SALE, NOR THE SOLICITATION OF AN OFFER TO BUY ANY SECURITIES. OCA ANTICIPATES THAT IT WILL FILE A REGISTRATION STATEMENT WITH THE SECURITIES AND EXCHANGE COMMISSION RELATING TO THE SHARES OF OCA COMMON STOCK THAT WOULD BE ISSUED UNDER THESE PROGRAMS. THAT REGISTRATION STATEMENT HAS NOT YET BEEN FILED OR BECOME EFFECTIVE. THOSE SHARES OF OCA COMMON STOCK MAY NOT BE SOLD, AND ANY OFFERS TO BUY THE SHARES MAY NOT BE ACCEPTED, UNTIL THE REGISTRATION STATEMENT BECOMES EFFECTIVE, AND ANY SUCH OFFER MAY BE WITHDRAWN OR REVOKED, WITHOUT OBLIGATION OR COMMITMENT OF ANY KIND, AT ANY TIME PRIOR TO NOTICE OF ACCEPTANCE GIVEN AFTER THE EFFECTIVE DATE OF THE REGISTRATION STATEMENT. ANY INDICATION OF INTEREST IN RESPONSE TO THIS COMMUNICATION WILL INVOLVE NO OBLIGATION OR COMMITMENT. NO SECURITIES WILL BE SOLD OR GRANTED IN ANY JURISDICTION IN WHICH THE OFFER, SOLICITATION OR SALE OF SUCH SECURITIES WOULD BE UNLAWFUL PRIOR TO REGISTRATION OR QUALIFICATION UNDER THE SECURITIES LAWS OF SUCH JURISDICTION. 2 3 INCENTIVES FOR AMENDING EXISTING EMPLOYMENT AGREEMENT AND ORTHALLIANCE AGREEMENT, OR ENTERING INTO NEW OCA AGREEMENT OCA may offer shares of its common stock to OrthAlliance Affiliated Practitioners as an incentive for these individuals and their professional entities to, prior to the Merger, either (a) 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 (b) enter into an OCA Business Services Agreement in replacement of their existing OrthAlliance Service or Consulting Agreement, effective as of the proposed Merger with OrthAlliance. These shares may be issued to eligible OrthAlliance Affiliated Practitioners generally on the following terms under OCA's: o Stock Pool Program; o Target Stock Program; o OrthAlliance Stockholder Bonus Program; and o High Participation Bonus Program. 1. STOCK POOL PROGRAM Under OCA's Stock Pool Program, OCA may grant shares of its common stock to eligible OrthAlliance Affiliated Practitioners who, along with their professional entity, no later than July 27, 2001, 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 effective as of the Merger, as follows: ANNUAL SERVICE FEE/TENURE BASED AMOUNT.

EXCEPT, FOR OrthAlliance Affiliated Practitioners who were issued shares of OrthAlliance common stock in connection with entering into their OrthAlliance Service or Consulting Agreement or their sale of assets or capital stock to OrthAlliance, who would instead be granted: (i) 900 shares, PLUS (ii) 200 shares for each additional 20 of those OrthAlliance Affiliated Practitioners who do so from June 30 - July 27, 2001. o June 30 - July 6, 2001: (i) 600 shares, PLUS (ii) 200 shares for each additional 20 of those OrthAlliance Affiliated Practitioners who do so from July 7 - 27, 2001. o July 7 - 13, 2001: (i) 500 shares, PLUS (ii) 200 shares for each additional 20 of those OrthAlliance Affiliated Practitioners who do so from July 14 - 27, 2001. o July 14 - 20, 2001: (i) 400 shares, PLUS (ii) 200 shares for each additional 20 of those OrthAlliance Affiliated Practitioners who do so from July 21 - 27, 2001. o July 21 - 27, 2001: (i) 300 shares. CLINICAL ADVISORY COMMITTEE MEMBERS. In addition, each of the 12 OrthAlliance Affiliated Practitioners who are selected by OCA and OrthAlliance, and agree, to serve on OCA's Clinical Advisory Committee upon the Merger may be granted 2,500 shares of OCA common stock if, by June 22, 2001, that individual and his or her professional entity (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 effective as of the Merger. 4 5 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. However, if that 90% minimum target is not achieved in a particular 12 calendar month period, but is achieved during one of the subsequent 12 calendar month periods prior to the third anniversary of the Merger, then the installment of shares would be issuable at that time. 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. 5 6 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. However, if that 90% minimum target is not achieved in a particular 12 calendar month period, but is achieved during one of the subsequent 12 calendar month periods prior to the eighth anniversary of the Merger, then the installment of the shares would be issuable at that time. 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. 8 9 3. ORTHALLIANCE STOCKHOLDER BONUS PROGRAM Several OrthAlliance Affiliated Practitioners have indicated that they received as consideration a large number of shares of OrthAlliance common stock in connection with originally entering into their OrthAlliance Service or Consulting Agreement or selling assets or capital stock to OrthAlliance, which have declined in value since the date of issuance.
