                                   THE COMPANY

     Apple was founded in July 1996 to provide practice management services to
orthodontic practices in the United States and Canada. The Company's objective
is to provide a full complement of practice management services designed to
drive internal growth by enhancing the ability of Affiliated Practices to: (i)
deliver quality, affordable orthodontic treatment primarily on a fee-for-service
basis; (ii) stimulate demand in their local markets by increasing consumer
awareness of the benefits, availability and affordability of orthodontic
treatment; and (iii) improve the productivity and profitability of their
practices. The Company will also seek to grow through the acquisition of
additional Affiliated Practices and the development of satellite offices that
complement geographic areas served by existing and future Affiliated Practices.
The Company will earn revenue by providing management, administrative,
development and other services to Affiliated Practices.

     The Company has entered into definitive agreements to acquire substantially
all the tangible and intangible assets and assume certain liabilities of, and
provide long-term management services to, the Founding Affiliated Practices. The
Founding Affiliated Practices include 31 orthodontists and 58 offices located in
13 states in the United States and in Calgary, Alberta. The Founding Affiliated
Practices were selected based on a variety of factors, including the competitive
and financial strengths and historical growth of their practices and the
potential for future growth in their markets. Apple also considered the local
and national reputations of the Founding Affiliated Practices within the
orthodontic services industry, their ability to manage multi-location practices
providing high levels of quality care and their desire to grow and improve the
operating efficiency of their respective practices. For the year ended December
31, 1996, the Founding Affiliated Practices had average patient revenues of
approximately $800,000.

     The orthodontic services industry is highly fragmented, with over 90% of
the approximately 9,000 orthodontists in the United States operating as sole
practitioners and less than 2% being affiliated with the only existing public
practice management company specializing in orthodontics. The industry currently
generates approximately $3.5 billion in annual gross revenues, which have grown
steadily at an average rate of 7.5% per year in recent years. Industry data and
management's experience indicate that the need for orthodontics significantly
exceeds the current demand.
    
                                       3
<PAGE>
     The Company's business strategy emphasizes (i) implementing a comprehensive
operating strategy designed to drive internal growth of the Affiliated Practices
and (ii) expanding the Company's network of Affiliated Practices through an
aggressive acquisition program.
   
     The primary elements of the Company's operating strategy are (i)
implementing practice-building and external marketing programs designed to
generate new patient starts through increased referrals from existing and former
patients and the use of multimedia advertising to stimulate demand for treatment
services, (ii) offering more affordable payment plans to patients to broaden the
market for orthodontic services, (iii) increasing the operating efficiency of
the Affiliated Practices by relieving the orthodontists from various
time-consuming administrative responsibilities and realizing economies of scale,
(iv) providing a systems-oriented approach to training and education of clinic
personnel to improve their communications with patients and potential patients
and increase their productivity, (v) developing satellite offices to expand the
geographic markets served by Affiliated Practices and (vi) utilizing customized
management information systems to provide detailed financial and operating data
and related analysis to Affiliated Practices and management. Each of these
elements is intended to drive the internal growth of the Affiliated Practices
while allowing them to maintain high levels of quality care.

     The Company has implemented its operating strategy at a prototype practice
owned and, until June 1996, operated by the Company's Chairman and CEO, John G.
Vondrak, D.D.S. This practice has grown substantially since 1989, when Dr.
Vondrak acquired it, to approximately $1.9 million of revenues in 1996, placing
it among the largest sole-practitioner orthodontic practices in the United
States. Among the factors contributing to this growth have been the Company's
practice-building program (consisting of a complete training and operating
program designed to maximize patient satisfaction levels, generate referrals
from existing and former patients and increase case acceptance rates, and
external marketing efforts, including television advertising focusing on
affordable payment programs offered by that practice. The Company believes this
prototype practice has a higher case acceptance rate than the industry average
and a higher than average percentage of new case starts generated from patient
referrals and multimedia advertising. Management believes that the results of
this practice demonstrate the effectiveness of the Company's operating strategy.
In July 1996, Dr. Vondrak transferred the operation of this practice to an
orthodontist who recently completed her education, so that he could devote his
time fully to the formation of the Company. Since this transfer, the continued
application of the Company's operating strategy has resulted in further
increases in case starts based on a comparison of the six-month period ended
December 31, 1996 to the corresponding period in the prior year.

     The Company also intends to pursue an aggressive expansion program designed
to strengthen its position in its current markets and expand its network of
Affiliated Practices into markets it does not currently serve. The Company
believes that, due to the highly fragmented nature of the industry, there are
numerous orthodontic practices that are attractive candidates to become
Affiliated Practices. Additionally, the Company plans to focus on candidates who
have strong reputations in their local markets and the desire to implement the
Company's operating strategy. The Company intends to leverage the reputations
and relationships of the orthodontists affiliated with the Founding Affiliated
Practices to identify and develop growth opportunities with candidates to become
future Affiliated Practices. Many of these orthodontists hold, or have
previously held, leadership roles in various state, regional and national
associations or are affiliated with or teach at graduate orthodontic programs at
dental schools. The Company believes the visibility and reputation of these
individuals, combined with the acquisition experience of management, will
provide the Company with certain advantages in identifying, negotiating and
consummating future acquisitions.

                   SUMMARY UNAUDITED PRO FORMA FINANCIAL DATA
                (IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA)

     The following summary unaudited pro forma financial information assumes
Apple has acquired the assets and assumed certain liabilities of the Founding
Affiliated Practices, and assumed certain liabilities related to those assets,
executed management service agreements with the Founding Affiliated Practices
pursuant to the Acquisitions and completed the Offering. This information is
derived from the unaudited pro forma consolidated financial statements of Apple
contained elsewhere in this Prospectus.

     The unaudited pro forma consolidated financial statements have been
prepared by the Company based on assumptions deemed appropriate by the Company.
These pro forma financial statements may not be indicative of actual results if
the transactions had occurred on the dates indicated or which may be realized in
the future. Neither expected benefits and cost reductions anticipated by the
Company nor all costs associated with the Company's present or future cost
structure have been reflected in such pro forma financial data. The pro forma
consolidated balance sheet as of December 31, 1996 gives effect to the
Acquisitions and the Offering as if such transactions had occurred on December
31, 1996. The pro forma consolidated statement of operations for the year ended
December 31, 1996 assumes the Company had completed those transactions on
January 1, 1996.

                                  RISK FACTORS

     IN ADDITION TO THE OTHER INFORMATION CONTAINED IN THIS PROSPECTUS,
PROSPECTIVE INVESTORS SHOULD CONSIDER THE FOLLOWING FACTORS IN EVALUATING THE
COMPANY AND ITS BUSINESS BEFORE PURCHASING ANY OF THE SHARES OF THE COMMON STOCK
OFFERED HEREBY. THIS PROSPECTUS CONTAINS FORWARD-LOOKING STATEMENTS THAT INVOLVE
RISKS AND UNCERTAINTIES. ACTUAL RESULTS COULD DIFFER FROM THOSE DISCUSSED IN THE
FORWARD-LOOKING STATEMENTS AS A RESULT OF CERTAIN FACTORS, INCLUDING THOSE SET
FORTH BELOW AND ELSEWHERE IN THIS PROSPECTUS.

ABSENCE OF COMBINED OPERATING HISTORY
   
     The Company was incorporated in July 1996 and has conducted no operations
to date other than in connection with the Offering and the Acquisitions. The
Company has entered into agreements to acquire substantially all the assets and
assume certain liabilities of the Founding Affiliated Practices concurrently
with the closing of the Offering. In connection with the consummation of the
Acquisitions, the Company is entering into agreements to provide management
services ("Service Agreements") to the Founding Affiliated Practices for
initial terms of 20 years (subject to early termination by either party for
"cause," which includes a material default by or bankruptcy of the other
party). The Founding Affiliated Practices have operated as separate independent
entities. There can be no assurance that the process of integrating the
management and administrative functions of the Founding Affiliated Practices
will be successful or that the recently assembled management group will be able
to manage effectively or profitably these operations and successfully implement
the Company's operating or expansion strategies. Failure by the Company to
successfully implement its operating and expansion strategies would have a
material adverse effect on the Company's business, financial condition and
results of operations. See "Business -- Strategy" and "-- Service
Agreements."
    
RELIANCE ON AFFILIATED PRACTICES AND ORTHODONTISTS
   
     The Company will receive fees for management services provided to the
Affiliated Practices under the Service Agreements. It will not employ
orthodontists or control the practice of orthodontics by the orthodontists
employed by the Affiliated Practices, and its management services revenue
generally will depend on revenue generated by the Affiliated Practices. In some
cases, the management fees will be based on the costs and expenses the Company
incurs in connection with providing management services. While the laws of some
states permit the Company to participate in the negotiations by Affiliated
Practices of managed care contracts, preferred provider arrangements and other
negotiated price agreements, the Affiliated Practices are the contracting
parties for all such relationships, and the Company will be dependent on the
Affiliated Practices for the success of those relationships. Accordingly, the
profitability of those payor relationships, as well as the performance of the
individual orthodontists employed by the Affiliated Practices, will affect the
Company's profitability. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations -- Overview" and "Business -- Service
Agreements."

     The revenue of the Affiliated Practices (and, therefore, the success of the
Company) is dependent on fees generated by the orthodontists employed by the
Affiliated Practices. In connection with the Service Agreements, each
orthodontist affiliated with a Founding Affiliated Practice will enter into an
employment agreement, substantially all of which will have a five-year term,
with the professional corporation or association in which that orthodontist owns
an equity interest (and which is a party to a Service Agreement). A substantial
reduction in the number of orthodontists employed by or associated with the
Affiliated Practices could have a material adverse effect on the financial
performance of the Company. The ability of the Affiliated Practices to replace
existing orthodontists by attracting new orthodontists may be constrained by the
limited number of new orthodontists completing post-graduate orthodontic
programs each year. Failure by the Affiliated Practices to employ a sufficient
number of orthodontists (whether by renewals of existing employment agreements
or otherwise) would have a material adverse effect on the Company's business,
financial condition and results of operations. See "Business -- Industry" and
"-- Orthodontist Employment Agreements."

<PAGE>
RISKS ASSOCIATED WITH EXPANSION STRATEGY
   
     The success of the Company's expansion strategy will depend on a number of
factors, including the Company's ability to (i) identify attractive and willing
candidates to become Affiliated Practices in suitable markets and in good
locations within those markets, (ii) affiliate with acceptable Affiliated
Practices on favorable terms, (iii) adapt the Company's structure to comply with
present or future legal requirements affecting the Company's arrangements with
Affiliated Practices and comply with regulatory and licensing requirements
applicable to orthodontists and facilities operated and services offered by
orthodontists, (iv) obtain suitable financing to facilitate its expansion
program and (v) expand the Company's infrastructure and management to
accommodate expansion. Identifying candidates to become Affiliated Practices and
proposing, negotiating and implementing economically feasible affiliations with
such groups can be a lengthy, complex and costly process. A shortage of
available orthodontists with the skills and experience sought by the Company
would have a material adverse effect on the Company's expansion opportunities.
Furthermore, the Company anticipates facing substantial competition from other
companies to establish affiliations with additional orthodontic practices. There
can be no assurance that the Company's expansion strategy will be successful,
that modifications to the Company's strategy will not be required, that the
Company will be able to effectively manage and enhance the profitability of
additional Affiliated Practices or that the Company will be able to obtain
adequate financing on reasonable terms to support its expansion program.
Furthermore, using shares of Common Stock as consideration for (or in order to
provide financing for) future acquisitions could result in significant dilution
to then-existing stockholders. In addition, future acquisitions accounted for as
purchases may result in substantial annual noncash amortization charges for
intangible assets in the Company's statements of operations. See
" -- Competition," " -- Substantial Dilution and Absence of Dividends,"
"Management's Discussion and Analysis of Financial Condition and Results of
Operations -- Overview" and "Business -- Business Strategy."
    
NEED FOR ADDITIONAL FINANCING
   
     The Company's expansion strategy will require substantial capital
resources. Capital is needed not only for the acquisition of the assets of
additional Affiliated Practices, but also for the effective integration,
operation and expansion of the Affiliated Practices. In addition, the Affiliated
Practices may from time to time require capital for renovation and expansion and
for the addition of equipment and technology. The Service Agreements provide for
advances by the Company to the Founding Affiliated Practices for working capital
requirements (including any deficits in cash flows of Founding Affiliated
Practices resulting from, among other things, development of satellite offices)
and other purposes. Such loans will generally bear interest at prime plus one
percent and will be repayable over varying periods of time not to exceed five
years. The extent to which the Company will be able or willing to use shares of
Common Stock to consummate acquisitions or provide future financing will depend
on its market value from time to time and, in the case of acquisitions, the
willingness of owners of potential Affiliated Practices to accept Common Stock
as full or partial payment of acquisition consideration. Using shares of Common
Stock for these purposes may result in significant dilution to then-existing
stockholders. The Company may require additional capital from outside financing
sources in order to continue its expansion program. Although the Company
currently believes it will be able to secure additional financing, there can be
no assurance that the Company will be able to obtain additional funds when
needed on satisfactory terms or at all. Any limitation on the Company's ability
to obtain additional financing could have a material adverse effect on the
Company's business, financial condition and results of operations. See
" -- Substantial Dilution and Absence of Dividends" and "Management's
Discussion and Analysis of Financial Condition and Results of
Operations -- Liquidity and Capital Resources."
    
PROCEEDS OF OFFERING PAYABLE TO AFFILIATES
   
     In connection with the closing of the Acquisitions, the Company will pay,
out of proceeds from the Offering, approximately $6.4 million in cash to the
owners of the Founding Affiliated Practices, including approximately $455,000 to
Dr. Vondrak for the acquisition of his practice. The Company will also use (i)
approximately $3.0 million of the proceeds from the Offering to repay the entire
principal and interest
    
                                       9
<PAGE>
   
amounts outstanding under the Convertible Notes, all of which are held by
TriCap, and to reimburse the expenses incurred by TriCap on behalf of the
Company in connection with the Offering and (ii) approximately $500,000 of such
proceeds to pay a financial advisory fee to TriCap Partners, L.L.C. ("TriCap
Partners"), an affiliate of TriCap, pursuant to a consulting agreement between
Apple and TriCap Partners. The Company has used $230,000 of the funds advanced
to it by TriCap to reimburse John G. Vondrak Apple Orthodontix, Inc., one of the
Founding Affiliated Practices ("JGVAOI"), for a portion of the organizational
expenses of Apple incurred by JGVAOI. The Company intends to reimburse JGVAOI an
additional $70,000 from the proceeds of the Offering to repay the remainder of
such expenses. See "Use of Proceeds" and "Certain Transactions -- Agreements
with TriCap."
    
GOVERNMENT REGULATION

     Various federal and state laws regulate the orthodontic services industry.
Regulatory oversight includes, but is not limited to, considerations of
fee-splitting and corporate practice of orthodontics.

     The laws of many states prohibit business corporations such as the Company
from engaging in the practice of orthodontics or employing orthodontists to
practice orthodontics and prohibit orthodontists from splitting fees with
non-orthodontists. The specific restrictions against the corporate practice of
orthodontics, as well as the interpretation of those restrictions by state
regulatory authorities, vary from state to state. The restrictions are generally
designed to prohibit a non-orthodontic entity (such as the Company) from
controlling the professional assets of an orthodontic practice (such as patient
records and payor contracts), employing orthodontists to practice orthodontics
(or, in certain states, employing dental hygienists or orthodontic assistants),
or controlling the content of an orthodontist's advertising or professional
practice. The laws of many states also prohibit orthodontists from sharing
professional fees with non-orthodontic entities. State orthodontic boards do not
generally interpret these prohibitions as preventing a non-orthodontic entity
from owning non-professional assets used by an orthodontist in an orthodontic
practice or providing management services to an orthodontist for a fee provided
certain conditions are met. The Company believes that its operations will not
contravene any restriction on the corporate practice of orthodontics and that
the management fees it intends to charge for its services are consistent with
the laws and regulations of the jurisdictions in which it will operate
concerning fee-splitting. There can be no assurance, however, that a review of
the Company's business relationships by courts or regulatory authorities will
not result in determinations that could prohibit or otherwise adversely affect
the operations of the Company or that the regulatory environment will not
change, requiring the Company to reorganize or restrict its existing or future
operations. The laws regarding fee-splitting and the corporate practice of
orthodontics and their interpretation are enforced by regulatory authorities
with broad discretion. There can be no assurance that the legality of the
Company's business or its relationship with the Affiliated Practices will not be
successfully challenged or that the enforceability of the provisions of any
Service Agreement will not be limited.
   
CONTROL BY EXISTING MANAGEMENT AND STOCKHOLDERS

     Following the completion of the Acquisitions and the Offering (and assuming
the Convertible Notes will be repaid in full with proceeds from the Offering and
will not be converted into shares of Common Stock), Dr. John G. Vondrak, the
Company's Chairman and Chief Executive Officer, the other executive officers and
directors of the Company as a group, and TriCap will beneficially own
approximately 38.6%, 11.3% and 41.0%, respectively, of the outstanding shares of
Class B Stock (or an aggregate of approximately 91.0%) and    %,    % and none,
respectively, of the outstanding shares of Common Stock (or an aggregate of
approximately ___%). The shares of Common Stock and Class B Stock beneficially
owned by Dr. Vondrak, such officers and directors as a group and TriCap
represent approximately    %,    % and 9.3%, respectively, of the voting power
of the capital stock of the Company (or an aggregate of approximately _____%).
These persons, if acting in concert, will be able to exercise control over the
    
                                       10
<PAGE>
Company's affairs, elect the entire Board of Directors and (subject to Section
203 of the Delaware General Corporation Law ("DGCL")) control the outcome of
any matter submitted to a vote of stockholders. See "Security Ownership of
Certain Beneficial Owners and Management."
   
DEPENDENCE ON KEY PERSONNEL

     The Company's future performance depends in significant part on the
continued service of its senior management and other key personnel. There can be
no assurance the Company's senior management and other key employees will
continue to work for the Company. Loss of services of those employees could have
a material adverse effect on the Company's business, results of operations and
financial condition. The success of the Company's growth strategy will also
depend on the Company's ability to attract and retain additional high quality
personnel. See "Business -- Employees" and "Management."
    
COMPETITION
   
     The Company anticipates facing substantial competition from other companies
to establish affiliations with additional orthodontic practices. The Company is
aware of one public and two private practice management companies focused on
orthodontics and several companies pursuing similar strategies in other segments
of the health care industry (including dentistry). Certain of these competitors
have greater financial and other resources than the Company (including more
established trading histories for their shares of common stock, which may be
used as currency in making acquisitions). Additional companies with similar
objectives may enter the Company's markets and compete with the Company. In
addition, the business of providing orthodontic services is highly competitive
in each market in which the Company will operate. Each of the Founding
Affiliated Practices faces local competition from other orthodontists, general
dentists and pedodontists (dentists specializing in the care of children's
teeth), some of whom have more established practices. Dentists are not
restricted by law or any governmental authority from providing orthodontic
services. Management believes the increase in recent years in dentists providing
orthodontic services has limited the growth of patient case starts performed by
orthodontists. There can be no assurance that the Company or the Affiliated
Practices will be able to compete effectively with their respective competitors,
that additional competitors will not enter their markets or that additional
competition will not have a material adverse effect on the Company. See
"Business -- Competition."

RISK OF PROVIDING ORTHODONTIC SERVICES; ADEQUACY OF INSURANCE COVERAGE

     The Affiliated Practices provide orthodontic services to the public and are
exposed to the risks of professional liability and other claims. Such claims, if
successful, could result in substantial damage awards to the claimants that may
exceed the limits of any applicable insurance coverage. Although the Company
will not control the practice of orthodontics by the Affiliated Practices, it
could be asserted that the Company should be held liable for malpractice of an
orthodontist employed by an Affiliated Practice. Each Affiliated Practice has
undertaken to comply with all applicable regulations and legal requirements, and
the Company maintains liability insurance for itself and it is anticipated that
the Company will be named as an additional insured party on the liability
insurance policies of the Affiliated Practices. The Founding Affiliated
Practices have agreed to maintain comprehensive professional liability
insurance, generally with limits of not less than $1.0 million per claim and
with aggregate policy limits of not less than $3.0 million per orthodontist and
the Founding Affiliated Practices will maintain a separate limit acceptable to
Apple. There can be no assurance, however, that a future claim or claims will
not be successful or, if successful, will not exceed the limits of available
insurance coverage or that such coverage will continue to be available at
acceptable costs. See "Business -- Litigation and Insurance."
    
LITIGATION WITH ORTHODONTIC CENTERS OF AMERICA
   
     On December 10, 1996, Orthodontic Centers of America, Inc. ("OCA") filed
a complaint in the United States District Court for the Eastern District of
Louisiana against Apple, Dr. Vondrak, John G. Vondrak, P.C. and JGVAOI alleging,
among other things, misappropriation of trade secrets and certain breaches of a
confidentiality agreement executed by Dr. Vondrak, on behalf of John Vondrak,
P.C., in favor of OCA. While Apple is not a party to the confidentiality
agreement, OCA has alleged that Apple should be
    
                                       11
<PAGE>
bound by its terms as a result of the relationship between Dr. Vondrak and Apple
(specifically, OCA has alleged that Dr. Vondrak and Apple are alter egos and,
alternatively, that Dr. Vondrak was acting as Apple's agent when he executed the
confidentiality agreement). The Company intends to vigorously defend against the
claims made by OCA, which the Company believes are without merit.

POTENTIAL EFFECT OF SHARES ELIGIBLE FOR FUTURE SALE ON PRICE OF COMMON STOCK

     The market price of the Common Stock of the Company could be adversely
affected by the sale of substantial amounts of the Common Stock in the public
market following the Offering. The shares being sold in the Offering will be
freely tradable unless acquired by affiliates of the Company.
   
     Concurrently with the closing of the Offering, security holders of the
Founding Affiliated Practices will receive, in the aggregate,          shares of
Common Stock as a portion of the consideration for the assets of their
practices. Certain other stockholders of the Company will hold, in the
aggregate, an additional 4,106,852 shares of Class B Stock. Those shares are not
being offered and sold pursuant to this Prospectus. None of those
shares were acquired in the transactions registered under the Securities Act of
1933, as amended (the "Securities Act"), and, accordingly, such shares may not
be sold except in transactions registered under the Securities Act or pursuant
to an exemption from registration. In addition, the holders of          of those
shares have agreed not to sell any shares of Common Stock owned by them
immediately after the consummation of the Acquisitions for a one-year period
following the Offering, subject to their right to exercise certain registration
rights. After the expiration of such restricted period, all of those shares may
be sold in accordance with Rule 144 under the Securities Act, subject to the
applicable volume limitations, holding period and other requirements of Rule
144. Substantially all of the outstanding shares of Class B Stock will become
eligible for resale pursuant to Rule 144 in October 1997, although such shares
will remain subject to a contractual resale restriction during the 180-day
period described in the following paragraph.

     The Company, its directors and executive officers, TriCap and all persons
acquiring shares of Common Stock in connection with the Acquisitions have agreed
not to offer or sell any shares of Common Stock for a period of 180 days (the
"180-Day Lockup Period") following the date of this Prospectus without the
prior written consent of Bear, Stearns & Co. Inc., except that the Company may
issue, subject to certain conditions, Common Stock in connection with
acquisitions and awards under the 1996 Stock Option Plan.

     Following completion of the Offering, the Company intends to register the
issuance of an additional 2,000,000 shares of its Common Stock under the
Securities Act subsequent to completion of the Offering for use by the Company
as all or a portion of the consideration to be paid in future acquisitions.
Those shares will generally be freely tradable by nonaffiliates after their
issuance, unless the sale thereof is contractually restricted. The Company
anticipates that the agreements entered into in connection with its future
acquisitions will contractually restrict the resale of all or a portion of the
shares issued in those transactions for varying periods of time.

     The Company anticipates that, prior to the consummation of the Offering,
the Company will have outstanding under the 1996 Stock Option Plan options to
purchase approximately 760,000 shares of Common Stock. The Company intends to
register the shares issuable upon exercise of options granted under the 1996
Stock Option Plan. See "Management -- 1996 Stock Option Plan" and "Shares
Eligible for Future Sale."
    
NO PRIOR MARKET; POSSIBLE VOLATILITY OF STOCK PRICE
   
     Prior to the Offering, there has been no public market for the Common
Stock, and there can be no assurance that an active trading market will develop
or, if a trading market does develop, that it will continue after the Offering.
The initial public offering price of the Common Stock, which will be determined
through negotiations between the Company and the Underwriters, may not be
indicative of the price at which the Common Stock will trade after the Offering.
The factors considered in making such determination will include the prevailing
market conditions, the financial condition and operating history of the Company

industry in general, the management of the Company and the market price of
securities for companies in businesses similar to that of the Company. The
securities markets have, from time to time, experienced significant price and
volume fluctuations that may be unrelated to the operating performance of
particular companies. These fluctuations often substantially affect the market
price of a company's common stock. The market prices for securities of physician
practice management companies have in the past been, and can in the future be
expected to be, particularly volatile. The market price of the Common Stock may
be subject to volatility from quarter to quarter depending on announcements
regarding the Affiliated Practices and their ability to open new treatment
centers, acquisitions by the Company or its competitors, government relations,
developments or disputes concerning proprietary rights, changes in reimbursement
levels, changes in health care policy in the United States and internationally,
the issuance of stock market analyst reports and recommendations, and economic
and other external factors, as well as operating results of the Company and
fluctuations in the Company's financial results. See "-- Fluctuations in
Operating Results" and "Underwriting."

FLUCTUATIONS IN OPERATING RESULTS

     The Company's results of operations may fluctuate significantly from
quarter to quarter or year to year. Results may fluctuate due to a number of
factors, including the timing of future acquisitions and satellite office
openings, seasonal fluctuations in the demand for orthodontic services and
competitive factors. Accordingly, quarterly comparisons of the Company's
revenues and operating results should not be relied on as an indication of
future performance, and the results of any quarterly period may not be
indicative of results to be expected for a full year. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations."
    
CERTAIN ANTI-TAKEOVER PROVISIONS
   
     Certain provisions of the Company's Restated Certificate of Incorporation
(the "Certificate of Incorporation") and Bylaws and of Delaware law could,
together or separately, discourage potential acquisition proposals, delay or
prevent a change in control of the Company or limit the price that certain
investors might be willing to pay in the future for shares of the Common Stock.
The Certificate of Incorporation provides for "blank check" preferred stock,
which may be issued without stockholder approval, provides for a "staggered"
Board of Directors and provides that stockholders may act only at an annual or
special meeting of stockholders and may not act by written consent. In addition,
certain provisions of the Company's Bylaws restrict the right of the
stockholders to call a special meeting of stockholders, to nominate directors,
to submit proposals to be considered at stockholders' meetings and to adopt
amendments to the Bylaws. The Company also is subject to Section 203 of the
DGCL, which, subject to certain exceptions, prohibits a Delaware corporation
from engaging in any of a broad range of business acquisitions with an
"interested stockholder" for a period of three years following the date such
stockholder became an interested stockholder. See "Description of Capital
Stock."

SUBSTANTIAL DILUTION AND ABSENCE OF DIVIDENDS

     Purchasers of shares of Common Stock offered hereby will experience
immediate and substantial dilution in the net tangible book value of their
shares in the amount of $      per share. See "Dilution." In the event the
Company issues additional Common Stock in the future, including shares that may
be issued in connection with future acquisitions, purchasers of Common Stock in
the Offering may experience further dilution in the net tangible book value per
share of Common Stock. The Company has never paid any cash dividends and does
not anticipate paying cash dividends on its Common Stock or Class B Stock in the
foreseeable future. See "Dividend Policy."

                                   THE COMPANY

     The Company was incorporated in July 1996 and has conducted no operations
to date other than in connection with the Offering and the Acquisitions. The
Company has entered into agreements to acquire substantially all the assets and
assume certain liabilities of the Founding Affiliated Practices concurrently
with the closing of the Offering. The Company's principal executive offices are
located at One West Loop South, Suite 100, Houston, Texas 77027, and its
telephone number is (713) 964-6882.
    
                                 USE OF PROCEEDS
   
     The net proceeds to the Company from the sale of the shares of Common Stock
offered hereby (after deducting the underwriting discounts and commissions and
estimated Offering expenses including the repayment of the entire principal and
interest amounts outstanding under the Convertible Notes issued to TriCap and
the expenses incurred by TriCap on behalf of the Company in connection with the
Acquisitions and the Offering) are estimated to be approximately $18.2 million
(approximately $21.9 million if the Underwriters' over-allotment option is
exercised in full).

     Of the $18.2 million of net proceeds, the Company intends to use (i)
approximately $6.4 million to pay the cash portion of the consideration for the
Acquisitions and (ii) $500,000 to pay a financial advisory fee to an affiliate
of TriCap. The remaining net proceeds will be used for general corporate
purposes, which are expected to include future acquisitions, the development of
satellite offices and future capital expenditures. Other than with respect to
the Acquisitions, the Company currently has no agreement or understanding with
respect to any future acquisitions. Pending such uses, the net proceeds will be
invested in short-term, interest bearing, investment grade securities. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operation -- Liquidity and Capital Resources."

     The Convertible Notes were issued in connection with loans made by TriCap
in the aggregate amount of $2.6 million to fund Apple's organizational and other
expenses incurred prior to the completion of the Offering. The Convertible Notes
bear interest at an average rate of 8.5% per annum and are convertible, at the
option of either Apple or TriCap, into shares of Common Stock at a conversion
price of $11.00 per share. Apple does not currently intend to exercise its
conversion rights with respect to the Convertible Notes and, based on a written
representation received from TriCap, does not expect TriCap to exercise its
conversion rights. Assuming the Convertible Notes are not converted, the
indebtedness represented thereby will mature and become due on the closing of
the Offering.
    
                                 DIVIDEND POLICY

     It is the Company's current intention to retain earnings for the
foreseeable future to support operations and finance expansion. The payment of
any future dividends will be at the discretion of the Company's Board of
Directors and will depend upon, among other things, the Company's earnings,
financial condition, cash flow from operations, capital requirements, expansion
plans, the income tax laws then in effect, the requirements of Delaware law and
restrictions that may be imposed in the Company's future financing arrangements.

                                    DILUTION
   
     The pro forma net tangible book value of the Company as of December 31,
1996 was $____ per share of Common Stock, after giving effect to the
Acquisitions. Pro forma net tangible book value per share is determined by
dividing the pro forma tangible net worth of the Company (pro forma tangible
assets less pro forma total liabilities) by the number of shares of Common Stock
and Class B Stock to be outstanding after giving effect to the Acquistions.
After giving effect to (i) the Acquisitions and (ii) the sale by the Company of
an estimated ____ shares of Common Stock offered at an assumed price of $_____
per share and the application of the estimated net proceeds therefrom as set
forth under "Use of Proceeds," the net pro forma tangible book value of the
Company as of December 31, 1996 would have been $____ per share. This
represents an immediate increase in the net tangible book value of $____ per
share to existing stockholders and an immediate dilution to new investors
purchasing Common Stock in the Offering of $____ per share. The following table
illustrates the per share dilution to new investors purchasing Common Stock in
the Offering:

     The dilution to new investors purchasing shares in the Offering will

the initial public offering price is lower, than $12.00 per share.
   
     The following table sets forth, on a pro forma basis to give effect to the
Acquisitions as of December 31, 1996, the number of shares of Common Stock and
Class B Stock purchased from the Company, the total consideration to the Company

                            SELECTED FINANCIAL DATA
                (IN THOUSANDS, EXCEPT SHARE AND PER SHARE DATA)

     The following selected pro forma financial information assumes Apple has
acquired the assets and assumed certain liabilities of the Founding Affiliated
Practices and assumed certain liabilities related to those assets, executed
Service Agreements with the Founding Affiliated Practices in connection with the
Acquisitions and completed the Offering and applied the net proceeds therefrom
as described under "Use of Proceeds." This information is derived from the
unaudited pro forma consolidated financial statements of Apple and audited
financial statements of Apple included elsewhere in this Prospectus.

     The unaudited pro forma consolidated financial statements have been
prepared by the Company based on data derived from the historical combined
financial statements of the Founding Affiliated Practices included elsewhere in
this Prospectus and assumptions deemed appropriate by the Company. The unaudited
pro forma financial statements may not be indicative of actual results that
might have been obtained if the transactions had occurred on the dates indicated
or that may be realized in the future. Neither expected benefits and cost
reductions anticipated by the Company nor all costs associated with the
Company's present or future cost structure have been reflected in the pro forma
financial data. The unaudited pro forma consolidated balance sheet as of
December 31, 1996 gives effect to the Acquisitions and the Offering as if those
transactions had occurred on December 31, 1996. The pro forma consolidated
statements of operations for the year ended December 31, 1996 assume the Company
had completed the transactions on January 1, 1996.

               MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                      CONDITION AND RESULTS OF OPERATIONS
   
     THE FOLLOWING DISCUSSION AND ANALYSIS CONTAINS CERTAIN STATEMENTS OF A
FORWARD-LOOKING NATURE RELATING TO FUTURE EVENTS OR THE FUTURE FINANCIAL
PERFORMANCE OF THE COMPANY. SUCH STATEMENTS ARE ONLY PREDICTIONS AND THE ACTUAL
EVENTS OR RESULTS MAY DIFFER MATERIALLY FROM THE RESULTS DISCUSSED IN THE
FORWARD-LOOKING STATEMENTS. FACTORS THAT COULD CAUSE OR CONTRIBUTE TO SUCH
DIFFERENCES INCLUDE, BUT ARE NOT LIMITED TO, THOSE DISCUSSED IN "RISK
FACTORS," AS WELL AS THOSE DISCUSSED ELSEWHERE IN THIS PROSPECTUS. THE
HISTORICAL RESULTS SET FORTH IN THIS DISCUSSION AND ANALYSIS ARE NOT INDICATIVE
OF TRENDS WITH RESPECT TO ANY ACTUAL OR PROJECTED FUTURE FINANCIAL PERFORMANCE
OF THE COMPANY. THIS DISCUSSION AND ANALYSIS SHOULD BE READ IN CONJUNCTION WITH
THE FINANCIAL STATEMENTS AND THE RELATED NOTES THERETO INCLUDED ELSEWHERE IN
THIS PROSPECTUS.
    
OVERVIEW
   
     The Company has conducted no significant operations to date but will be
acquiring, in connection with the Acquisitions, tangible and intangible assets
and liabilities of, and entering into Service Agreements with, the Founding
Affiliated Practices. The Company expects that its future growth will come from
(i) implementing a comprehensive operating strategy designed to drive internal
growth of the Affiliated Practices and (ii) entering into Service Agreements
with new Affiliated Practices and developing new orthodontic centers (including
satellite offices) with existing and future Affiliated Practices.

     Through its Service Agreements, the Company will be providing a full
complement of practice management services to the Founding Affiliated Practices
in return for management service fees. In general, the Company's management
service revenue will be based upon the revenue generated by the Founding
Affiliated Practices, less amounts retained by the orthodontic entity. In other
cases, the Company's management fee will be based on a percent of revenue
generated by the Founding Affiliated Practices plus the reimbursement of
expenses. In either case, patient revenue generated by a Founding Affiliated
Practice will be calculated as the total of (i) 24% of the aggregate contract
amounts for new patient contracts entered into by that Founding Affiliated
Practice during that month and (ii) the aggregate of the monthly contract
residuals of that Founding Affiliated Practice's pre-existing patient contracts
(I.E., 76% of each contract amount pro rated on a monthly basis over the
treatment period). This revenue computation methodology is based on the
Company's understanding of accepted industry convention and is only an element
of the service fee calculation. The amount retained by the orthodontic entity
will generally be dependent on its financial performance, based on cash receipts
and disbursements provided in the Service Agreements. Accordingly, orthodontists
affiliated with an Affiliated Practice generally will have a financial incentive
to maximize profits of the Affiliated Practice. For a more complete description
of the Service Agreements, see "Business -- Service Agreements."
    
     The expenses incurred by the Company in fulfilling its obligations under
the Service Agreements are generally of the same nature as the operating costs
and expenses that would have otherwise been incurred by the Founding Affiliated
Practices, including salaries, wages and benefits of practice personnel
(excluding orthodontists and, in some cases, orthodontic assistants and other
professional personnel), orthodontic supplies and office supplies used in
administering their clinic practices, the office (general and administrative)
expenses of the practices and depreciation and amortization of assets acquired
from the Founding Affiliated Practices. In addition to the operating costs and
expenses discussed above, the Company will be incurring personnel and
administrative expenses in connection with establishing and maintaining a
corporate office, which will provide management, administrative, marketing and
development and acquisition services.
   
     In accordance with Staff Accounting Bulletin ("SAB") No. 48, "Transfers
of Nonmonetary Assets by Promoters or Shareholders," published by the
Securities and Exchange Commission (the "Commission"), the acquisition of the
assets and assumption of certain liabilities for all of the Founding Affiliated
Practices pursuant to the Acquisitions are accounted for by the Company at the
transferors' historical cost basis, with the shares of common stock to be issued
in those transactions being valued at the historical cost of the nonmonetary
assets acquired net of liabilities assumed. The cash consideration will be
reflected as a dividend by Apple to the owners of the Founding Affiliated
Practices. SAB No. 48 will not be applicable to any acquisitions made by the
Company subsequent to the Offering. It is currently anticipated that the
Company's future acquisitions of certain of the assets and liabilities of

accounted for using the purchase method of accounting. Future acquisitions
accounted for as purchases may result in substantial annual noncash amortization
charges for intangible assets in the Company's statements of operations.
    
RESULTS OF OPERATIONS

  HISTORICAL
   
     The Company has conducted no significant operations to date and will not
conduct significant operations until the Acquisitions and the Offering are
completed. General and administrative expenses were incurred during the year
ended December 31, 1996 in connection with this Offering. The Company has
incurred and will continue to incur various legal, accounting, travel, personnel
and marketing costs in connection with the Acquisitions and the Offering, $2.6
million of which is being funded through the issuance of Convertible Notes to
TriCap and $0.4 million of which is being funded by other advances from TriCap.
The Convertible Notes are expected to be repaid from the proceeds of the
Offering. See "Use of Proceeds."
    
  PRO FORMA
   
     REVENUES.  It is anticipated that substantially all the Company's revenues
will consist of fees under the Service Agreements. The revenues included in the
unaudited pro forma financial statements are calculated by applying the terms of
the Service Agreements to the historical financial results of the Founding
Affiliated Practices for the year ended December 31, 1996, assuming the
Acquisitions had been completed as of January 1, 1996.

     OPERATING EXPENSES.  The total pro forma operating expenses do not reflect
cost reductions anticipated by the Company or the additional corporate costs
that the Company will incur in the future (which will be material). Furthermore,
the pro forma operating expenses are based on the expenses incurred by Apple for
the period from inception, July 15, 1996, through December 31, 1996. No
adjustment was made for expenses that may have been incurred if the Company was
organized on January 1, 1996. However, the expenses of the Company do reflect
pro forma adjustments to include the costs and expenses of the Founding
Affiliated Practices that will be assumed by Apple.
    
     PROVISION FOR INCOME TAXES.  Pro forma income taxes assume that the Company
had operated as a tax-paying entity for the year ended December 31, 1996,
subject to an effective combined tax rate for state and federal income taxes of
38% for the period.

LIQUIDITY AND CAPITAL RESOURCES
   
     If the Acquisitions had occurred on December 31, 1996, the Company would
have had pro forma working capital of $10.9 million at that date. The
approximately $1.0 million of pro forma indebtedness of the Company as of
December 31, 1996 consists primarily of capital lease obligations, debt of the
practices that Apple has agreed to assume and financing provided by TriCap.

     The Company anticipates making routine capital expenditures for the
Founding Affiliated Practices during the remainder of 1997 of approximately $2.0
million to fund, among other things, the development of satellite offices. The
average cost of developing a satellite office (which may vary by geographic
market) is estimated to be approximately $250,000, including initial working
capital requirements. The Service Agreements provide for advances by the Company
to the Founding Affiliated Practices for working capital requirements (including
any deficits in cash flows of Founding Affiliated Practices resulting from,
among other things, development of satellite offices) and other purposes. Such
loans will generally bear interest at prime plus one percent and will be
repayable over varying periods of time not to exceed five years. It is
anticipated that the foregoing capital expenditures will be funded from the
Company's cash flow from operations. The Company also expects to make
acquisitions of additional orthodontic practices during 1997 that will involve
the use of cash and Common Stock.

     Management believes that the existing cash proceeds of the Offering
combined with its cash flow from operations will be sufficient to fund planned
capital expenditures and ongoing operations of the Company through the end of
1998. The Company is also seeking to establish a revolving bank credit facility
and intends to register two million additional shares of Common Stock which,
when combined with the Company's cash resources, will be used in the Company's
planned acquisition program.

                                    BUSINESS

OVERVIEW
   
     Apple was founded in July 1996 to provide practice management services to
orthodontic practices in the United States and Canada. The Company's objective
is to provide a full complement of practice management services designed to
drive internal growth by enhancing the ability of Affiliated Practices to: (i)
deliver quality, affordable orthodontic treatment primarily on a fee-for-service
basis; (ii) stimulate demand in their local markets by increasing consumer
awareness of the benefits, availability and affordability of orthodontic
treatment; and (iii) improve the productivity and profitability of their
practices. The Company will also seek to grow through the acquisition of
additional Affiliated Practices and the development of satellite offices that
complement existing geographic areas served by existing and future Affiliated
Practices. The Company will earn revenue by providing management,
administrative, development and other services to Affiliated Practices.

     The Company has entered into definitive agreements to acquire substantially
all the tangible and intangible assets and assume certain liabilities of, and
provide long-term management services to, the Founding Affiliated Practices. The
Founding Affiliated Practices include 31 orthodontists and 58 offices located in
13 states in the United States and in Calgary, Alberta. The Founding Affiliated
Practices were selected based on a variety of factors, including the competitive
and financial strengths and historical growth of their practices and the
potential for future growth in their markets. Apple also considered the local
and national reputations of the Founding Affiliated Practices within the
orthodontic services industry, their ability to manage multi-location practices
providing high levels of quality care and their desire to grow and improve the
operating efficiency of their respective practices. For the year ended December
31, 1996, the Founding Affiliated Practices had average patient revenues of
approximately $800,000.
    
INDUSTRY
   
     INDUSTRY OVERVIEW.__The orthodontic services industry is highly fragmented,
with over 90% of the approximately 9,000 orthodontists in the United States
operating as sole practitioners and less than 2% being affiliated with the only
existing public practice management company specializing in orthodontics. The
industry currently generates approximately $3.5 billion in annual gross
revenues, which have grown steadily at an average rate of 7.5% per year in
recent years. Based on published industry data, over 70% of orthodontic
treatments are performed on a private pay, fee-for-service basis, 25% of
treatments are covered by traditional forms of dental insurance (generally with
a 50% or greater co-payment by the patient) and the remaining 5% of treatments
involve other payment methods, including managed care networks. Managed care
represents only a small portion of the payor sources due to the elective nature
of most orthodontic treatments. Most orthodontic practices (including all the
Founding Affiliated Practices) do not accept payment by Medicare or Medicaid.

     Orthodontic treatments are principally provided by orthodontists who have
completed three years of post-graduate studies following graduation from dental
school. The number of orthodontists in the United States has grown slowly since
1990, which management believes can be attributed to the limited number of
schools offering post-graduate orthodontic programs and the small class size at
each of those schools. In addition to orthodontists, a number of dentists
provide various orthodontic services. The industry information set forth in this
Prospectus does not include orthodontic treatments provided by dentists.
    
     The table below summarizes certain information from the 1995 JCO Study
concerning the United States orthodontic services industry for each of the years
presented:

</TABLE>
   
     Based on a 1994 study performed by the Department of Orthodontics,
University of Florida College of Dentistry (the "University of Florida Study")
and management's experience, the Company believes the
    
                                       20
<PAGE>
need for orthodontics significantly exceeds the current demand. The University
of Florida Study, which was funded by a grant from the National Institute of
Dental Research, concluded that only approximately one out of every five
children who need orthodontics receives treatment. The University of Florida
Study also indicated that cost was a barrier to orthodontics. Children in higher
socioeconomic groups received treatment approximately six times more often than
children in lower groups despite no measurable difference in need among the
groups. The University of Florida Study did not address the market potential for
adult patients, which management believes is significant. The Company believes
there is significant opportunity to expand the orthodontic treatment population
through improved public awareness of the benefits, availability and
affordability of orthodontic treatment.
   
     THE TRADITIONAL ORTHODONTIC PRACTICE.__The traditional orthodontic practice
typically involves a single orthodontist, practicing at one primary location or
with an average of less than one satellite office, with a small number of
orthodontic assistants and business office personnel and, in some cases, an
orthodontic associate. According to the 1995 JCO Study, the average orthodontist
initiated treatment of 170 new patients in 1994 and maintained approximately 380
active cases. In addition, the 1995 JCO Study reports that only 1.3% of
orthodontists use television advertising to promote their practices. In the
traditional practice, the orthodontist manages all business aspects of the
practice. The use of third-party management services is not typical.

     On an individual practice basis, the 1995 JCO Study reported median annual
revenues of $475,000 and median operating income of $191,000 in 1994. The median
overhead as a percentage of revenues was 55%, resulting in a 40% median
operating margin before orthodontist compensation, interest and taxes. Median
down payments were equal to approximately 25% of the total treatment cost.
Median case starts and active treatment cases were 170 and 360 per practice,
respectively. Individual practices on average generated over one-half of their
referrals from dentists. Less than 7% of the practices utilized commercial
advertising as a referral source. The median case acceptance rate (number of
case starts divided by the number of examinations) was 60%. Orthodontists
believed they had the ability to increase case starts by 30%, yet the median
case starts have not increased significantly since 1981, the first year of data
presented in the study.

THE APPLE ORTHODONTIX APPROACH

     The Company believes the traditional orthodontic practice is inefficient
and administratively burdensome to orthodontists, and can be financially
burdensome to patients, who traditionally pay approximately 25% of the total
contract amount as a down payment ($875 when applied to the average fee per case
in 1994, according to the 1995 JCO Study). The Company has developed a
comprehensive operating strategy designed to improve efficiency, increase the
number of new case starts and active cases handled by each orthodontist and
relieve orthodontists associated with Affiliated Practices of time-consuming
administrative responsibilities. As part of its operating strategy, the Company
will assist its Affiliated Practices in developing satellite offices to expand
the scope of the geographic areas they serve. The Company will also assist
Affiliated Practices in developing and implementing payment programs designed to
make orthodontic services more affordable to prospective patients, thereby
making their services available to a larger segment of the population in their
respective markets.

     The Company has implemented its operating strategy at a prototype practice
owned and, until June 1996, operated by the Company's Chairman and CEO, John G.
Vondrak, D.D.S. This practice has grown substantially since 1989, when Dr.
Vondrak acquired it, to approximately $1.9 million of revenues in 1996, placing
it among the largest sole-practitioner orthodontic practices in the United
States. Among the factors contributing to this growth have been the Company's
practice-building program (consisting of a complete training and operating
program emphasizing clear, concise and consistent communications to existing and
prospective patients in order to maximize satisfaction levels, generate
referrals and increase new case acceptance rates) and external marketing
efforts, including television advertising focusing on affordable payment plans
offered by that practice. The Company believes this prototype practice has a
higher case acceptance rate than the industry average and a higher than average
percentage of new case starts generated from patient referrals and multimedia
advertising.
    
                                       21
<PAGE>
   
     The Company believes its approach provides unique benefits to orthodontists
who choose to affiliate with it by providing opportunities for the orthodontist
to: (i) drive internal growth by implementing the Company's operating strategy;
(ii) share in the increased profitability resulting from internal growth; (iii)
lower costs through economies of scale; (iv) participate in a cost-effective
national advertising program; (v) focus on patient care; and (vi) enhance
liquidity and diversification.
    
BUSINESS STRATEGY

     The Company's business strategy emphasizes (i) implementing a comprehensive
operating strategy designed to drive internal growth of the Affiliated Practices
and (ii) expanding the Company's network of Affiliated Practices through an
aggressive acquisition program.
   
     OPERATING STRATEGY.__The primary elements of the Company's operating
strategy are (i) implementing practice-building and external marketing programs
designed to generate new patient starts through increased referrals from
existing and former patients and the use of multimedia advertising to stimulate
demand for treatment services, (ii) offering more affordable payment plans to
patients to broaden the market for orthodontic services, (iii) increasing the
operating efficiency of the Affiliated Practices by relieving the orthodontists
from various time-consuming administrative responsibilities and realizing
economies of scale, (iv) providing a systems-oriented approach to training and
education of clinic personnel to improve their communications with patients and
potential patients and increase their productivity, (v) developing satellite
offices to expand the geographic markets served by Affiliated Practices and (vi)
utilizing customized management information systems to provide detailed
financial and operating data and related analysis to Affiliated Practices and
management. Each of these elements is intended to drive the internal growth of
the Affiliated Practices while allowing them to maintain high levels of quality
care.

     Management believes that the results of the prototype practice owned by Dr.
Vondrak demonstrate the effectiveness of the Company's operating strategy. In
July 1996, Dr. Vondrak transferred the operation of this practice to an
orthodontist who recently completed her education, so that he could devote his
time fully to the formation of the Company. Since this transfer, the continued
application of the Company's operating strategy has resulted in further
increases in case starts based on a comparison of the six-month period ended
December 31, 1996 to the corresponding period in the prior year.

     EXPANSION STRATEGY.  The Company intends to pursue an aggressive expansion
strategy designed to strengthen its position in its current markets and expand
its network of Affiliated Practices into markets it does not currently serve.
The Company believes that, due to the highly fragmented nature of the industry,
there are numerous orthodontic practices that are attractive candidates to
become Affiliated Practices. Additionally, the Company plans to focus on
candidates who have strong reputations in their local markets and the desire to
implement the Company's operating strategy. The Company intends to leverage the
reputations and relationships of the orthodontists affiliated with the Founding
Affiliated Practices to identify and develop growth opportunities with
candidates to become future Affiliated Practices. Many of these orthodontists
hold, or have previously held, leadership roles in various state, regional and
national associations or are affiliated with or teach at graduate orthodontic
programs at dental schools. The Company believes the visibility and reputation
of these individuals, combined with the acquisition experience of management,
will provide the Company with certain advantages in identifying, negotiating and
consummating future acquisitions.

     As consideration for future acquisitions, the Company intends to use
various combinations of its Common Stock, cash and notes. The Company intends to
register two million additional shares of Common Stock under the Securities Act
subsequent to completion of the Offering for use in connection with future
acquisitions. These shares will generally be freely tradeable by non-affiliates
after their issuance, unless the sale thereof is contractually restricted. The
Company anticipates that the agreements entered into in connection with its
future acquisitions will contractually restrict the resale of all or a portion
of the shares issued in those transactions for varying periods of time.
    
                                       22
<PAGE>
SERVICES AND OPERATIONS

     The Company will manage all aspects of the Affiliated Practices operations
other than the provision of orthodontic treatment. The Company will employ all
business personnel at the offices of the Affiliated Practices and, where
permitted by applicable law and governmental regulations, also will employ the
orthodontic assistants.

     ADMINISTRATIVE.  The Company will earn revenue by providing management and
other services to the Affiliated Practices, including staffing, education and
training, billing and collections, cash management, purchasing, inventory
management, payroll processing, employee benefits administration, advertising
production and other marketing support, patient scheduling, financial reporting
and analysis, productivity reporting and analysis, associate recruiting and
support for acquisitions, new site development and other capital requirements.
The Company believes the orthodontists at the Affiliated Practices will benefit
from the administrative and management support provided by Apple and that these
services will substantially reduce the amount of time the orthodontists are
required to spend on administrative matters and will enable them to dedicate
more time to the growth of their professional practices. Management believes
that through economies of scale the Company will be able to provide these
services at a lower cost than could be obtained by each of the Affiliated
Practices individually. In addition, the Company believes that, due to its size
and purchasing power, it will be able to negotiate discounts on, among other
things, orthodontic and office supplies, health and malpractice insurance and
equipment.
   
     PRACTICE-BUILDING PROGRAM.  Management believes patient satisfaction
levels, practice productivity and profitability can be substantially enhanced
through a consistent training program emphasizing practice-building techniques.
The Company will implement programs designed to generate growth in case starts
by increasing (i) referrals from existing and former patients and (ii) case
acceptance rates. These programs include a full complement of training,
operating and monitoring techniques emphasizing improvements in communications
with patients and patient satisfaction levels in all facets of operations,
including initial telephone contacts with prospective patients, initial
consultations and case presentations and written or telephonic follow-ups after
office visits. The Company's programs are designed to result in clear, concise
and consistent communications between the patient and the orthodontist and his
or her staff. It is management's belief that these programs will have a positive
effect on the patients' experience and therefore positively impact the number of
patient referrals and case acceptance rates of Affiliated Practices.
    
     EXTERNAL MARKETING.  The Company and the Affiliated Practices will utilize
multimedia advertising in local markets to stimulate demand for orthodontic
treatment and promote name recognition for Apple and the Affiliated Practices.
The general public traditionally has had little information about the
availability of orthodontic services or orthodontic fees prior to an initial
consultation with an orthodontist. The advertisements will address the two
primary barriers to receiving orthodontic treatment, availability and
affordability, by focusing on the availability of orthodontic services and the
more affordable payment plans offered by the Affiliated Practices. The
advertisements will also stress the quality of care available at the Affiliated
Practices and the advantage of receiving orthodontic treatment from a
professionally trained orthodontist as opposed to a general dentist, and will
promote a toll-free number for ease of scheduling an appointment with the local
Affiliated Practice.
   
     Generally, it is anticipated that an Affiliated Practice will spend an
amount equal to between 5% and 7% of its net revenues for advertising and
marketing, which the Company believes is significantly higher than the industry
average for traditional orthodontic practices. The Company will be responsible
for subcontracting the production of all broadcast advertising, which will be
tailored to meet local requirements. Advertisements will generally be 30-second
television commercials and will include the names of the affiliated
orthodontists and the Company. The frequency and airing times for these
television ads will be determined by regional media consultants retained by
Apple and the Affiliated Practice in order to optimize penetration to target
market segments.

     AFFORDABLE PAYMENT PLANS.__Orthodontic services primarily involve private
pay, fee-for-service treatments. As part of its overall marketing strategy for
the Affiliated Practices, the Company intends to encourage the Affiliated
Practices to make orthodontic services available to a larger portion of the
    
                                       23
<PAGE>
population in their respective markets by offering more affordable payment
plans. Many of the Founding Affiliated Practices have historically received a
down payment equal to 25% of the total cost of services, with the remaining
amount paid equally over the term of treatment. It is contemplated that the
typical payment plan utilized after the Offering would consist of a modest
initial down payment and monthly payments thereafter for the duration of the
treatment period, generally between 26 and 34 months. The Company believes that
offering more affordable payment plans combined with the use of advertising will
result in an increase in the number of patients inquiring about orthodontic
treatment. The Company also believes that this anticipated increase combined
with the use of its internal marketing programs will result in an increase in
the number of patients receiving orthodontic treatment at the Affiliated
Practices.

     SATELLITE OFFICES.  The Company intends to develop additional satellite
offices (or branch locations) within selected markets served by the Affiliated
Practices. The Company believes that the satellite offices will increase the
geographic area served by the Affiliated Practices, thereby (i) increasing the
potential market, (ii) leveraging the advertising budget of the Affiliated
Practices and (iii) achieving critical mass within its existing markets. It is
anticipated that the satellite offices will generally be located in high
traffic, retail-oriented areas.
   
     Satellite offices developed by the Company will be staffed either on a
part-time basis by an orthodontist from an Affiliated Practice or on a full-time
basis by a newly recruited orthodontist, depending on the potential for
additional patients. The average cost of developing a satellite office (which
may vary by geographic market) is estimated to be approximately $250,000,
including initial working capital requirements. The Company will provide
management services and capital to develop satellite offices. The Company will
be responsible for selecting the site, negotiating the lease, designing the
office layout and furnishing the satellite office. The Company will also assist
the Affiliated Practices in recruiting orthodontists and support staff for those
satellite offices, which will be open full-time.
    
     TRAINING AND EDUCATION.  Staff and practice development programs are an
integral part of the Company's operating strategy. The Company believes its
programs will (i) increase the motivation and overall performance of the staff,
(ii) improve the level of patient satisfaction achieved by the Affiliated
Practices and (iii) improve the Company's ability to attract and retain
qualified personnel, which will collectively result in increased referrals from
existing and former patients and increased case acceptance rates for the
Affiliated Practices. The Company will provide each Affiliated Practice with
consulting and educational services. These services include a full training
program covering all non-orthodontic aspects of the practice and specific
training designed for the efficient and effective use of the Company's
management information system.
   
     Specifically, the Company's training program will provide each member of
the practice, from the receptionist to the orthodontist, with guidelines for
addressing questions and concerns of prospective and existing patients,
techniques for explaining treatment procedures and length of treatment,
parameters for establishing appropriate financial arrangements with each patient
and a systematic approach to monitoring the success of each area of training.
Training will be conducted both at individual clinics and in group sessions and
will include proprietary manuals, tapes and role playing activities.

     MANAGEMENT INFORMATION SYSTEMS.  The Company believes access to accurate,
relevant and timely financial and operating information is a key element to
providing practice management services to orthodontic practices. The Company
will offer a fully integrated financial reporting, productivity management and
patient management system at each Affiliated Practice. These systems are
designed to increase the productivity of the Affiliated Practices by enabling
the Company and the Affiliated Practices to cost-effectively monitor the
productivity of the Affiliated Practices, identify problem areas and
opportunities for improvement and advise on corrective action in a timely
manner. Productivity measures to be monitored will include case acceptance
rates, treatment times and case starts. In addition, the management information
systems will facilitate optimization of the orthodontists' time through
computerized scheduling and diagnostic and treatment recordkeeping systems. The
Company believes these systems will also improve the productivity of the
Affiliated Practices through benchmarking programs that identify and help
establish the most efficient operational procedures. As of the date of this
Prospectus, seven of the 31 Founding Affiliated
    
                                       24
<PAGE>
Practices have installed the Company's management information system. This
system will be made available to the remaining Affiliated Practices following
the closing of the Acquisitions.

SERVICE AGREEMENTS
   
     Upon consummation of the Acquisitions, the Company will enter into a
Service Agreement with each Founding Affiliated Practice under which the Company
will become the exclusive manager and administrator of non-orthodontic services
relating to the operation of the Founding Affiliated Practice. The following is
intended to be a brief summary of the typical form of Service Agreement the
Company will enter into with each Founding Affiliated Practice. The Company
expects to enter into similar agreements with Affiliated Practices in the
future. The actual terms of the various Service Agreements vary from the
description below on a case-by-case basis, depending on negotiations with the
individual Founding Affiliated Practices and the requirements of applicable law
and governmental regulations.

     The service fees (the "Service Fees") payable to the Company by the
Founding Affiliated Practices under the Service Agreements vary based on the
fair market value, as determined in arm's-length negotiations, for the nature
and amount of services provided. Such fees are payable monthly and will be
calculated pursuant to one of the following formulas: (i) a percentage of
revenues resulting from orthodontist services plus expenses, or (ii) revenues
relating to orthodontist services less an amount to be retained by orthodontists
based on collections resulting from orthodontist services subject to certain
adjustments. In addition, with respect to one of the Founding Affiliated
Practices, the service fees are based on flat fees that are subject to
renegotiation on an annual basis. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations -- Overview."
    
     Pursuant to each Service Agreement, the Company will, among other things,
(i) act as the exclusive manager and administrator of non-orthodontist services
relating to the operation of the Founding Affiliated Practice, subject to
matters reserved to the Founding Affiliated Practice, (ii) administer the
billing of patients, insurance companies and other third-party payors and
collect on behalf of the Founding Affiliated Practice the fees for professional
orthodontic and other services and products rendered or sold by the Founding
Affiliated Practice, (iii) provide, as necessary, clerical, accounting, payroll,

and duplication services and transcribing services, (iv) supervise and maintain
custody of substantially all files and records, (v) provide facilities,
equipment and furnishings for the Founding Affiliated Practice, (vi) prepare, in
consultation with the Affiliated Practice, all annual capital and operating
budgets, (vii) order and purchase inventory and supplies as reasonably requested
by the Founding Affiliated Practice and (viii) implement, in consultation with
the Founding Affiliated Practice, advertising programs.

     Under each Service Agreement, the applicable Founding Affiliated Practice
retains the responsibility for, among other things, (i) hiring, compensating and
supervising orthodontist employees and other licensed dental professionals, (ii)
ensuring that orthodontists have the required licenses, credentials, approvals
and other certifications appropriate to the performance of their duties and
(iii) complying with federal and state laws, regulations and ethical standards
applicable to the practice of orthodontics. In addition, the Founding Affiliated
Practice will be exclusively in control of all aspects of the practice of
orthodontics and the provision of orthodontic services.

     Each Service Agreement is for an initial term of twenty years, with
automatic extensions (unless specified notice is given) of five years. The
Service Agreement may be terminated by either party if the other party (i) files
a petition in bankruptcy or other similar events occur or (ii) defaults in the
performance of a material duty or obligation, which default continues for a
specified term after notice. In addition, the Service Agreement may be
terminated by the Company (i) if the Founding Affiliated Practice or an
orthodontist employee engages in conduct for which the orthodontist employee's
license to practice dentistry is revoked or suspended or is the subject of any
restrictions or limitations by any governmental authority to such an extent that
he, she or it cannot engage in the practice of orthodontics or (ii) upon the
death, disability or retirement of the orthodontist.
    
     During the term of the Service Agreement and, subject to certain
limitations, for a period of two years thereafter, the Founding Affiliated
Practice agrees not to compete with the Company or the other practices for which
the Company provides management services within a specified geographic area. The
Founding Affiliated Practice also agrees not to disclose certain confidential
and proprietary information relating to the Company and the Affiliated
Practices.
   
     The Founding Affiliated Practice is responsible for obtaining professional
liability insurance for the employees of the Founding Affiliated Practice (and
which will name the Company as an additional insured), and the Company is
responsible for obtaining general liability and property insurance for the
Founding Affiliated Practice.

     Upon termination of a Service Agreement, the Founding Affiliated Practice
has the option to purchase and assume, and the Company has the option to require
the Founding Affiliated Practice to purchase and assume, the assets and
liabilities related to the Founding Affiliated Practice (with the assets being
valued for those purposes at the fair market value thereof), except in certain
circumstances where the Founding Affiliated Practice or the Company, as
applicable, was in breach of the Service Agreement.
    
ORTHODONTIST EMPLOYMENT AGREEMENTS
   
     Upon consummation of the Acquisitions, each Founding Affiliated Practice
will be a party to an employment agreement with each orthodontist associated
with its practice (the "Orthodontist Employment Agreements"), including each
orthodontist who will receive cash or Common Stock in the Acquisition of such
Founding Affiliated Practice. Substantially all the Orthodontist Employment
Agreements with orthodontists who will receive cash or Common Stock in the
Acquisitions are for an initial term of five years, and continue thereafter on a
year-to-year basis until terminated under the terms of the agreements. If
employment of an orthodontist is terminated during the initial term for any
reason other than the orthodontist's death or disability or the occurrence of
certain events outside the orthodontist's control, the orthodontist will be
required to pay to the Founding Affiliated Practice liquidated damages. The
Orthodontist Employment Agreements provide that the employee orthodontist will
not compete with the Affiliated Practice during the term of the agreement and
following the termination of the agreement for a term of two years in a
specified geographical area, if termination occurs within the initial term, or
for one year if termination occurs after the initial term.
    
                                       26

COMPETITION
   
     The Company anticipates facing substantial competition from other companies
to establish affiliations with additional orthodontic practices. The Company is
aware of one public and two private practice management companies focused on
orthodontics and several companies pursuing similar strategies in other segments
of the health care industry (including dentistry). Certain of these competitors
have greater financial and other resources than the Company (including more
established trading histories for their shares of common stock, which may be
used as currency in making acquisitions). Additional companies with similar
objectives may enter the Company's markets and compete with the Company. In
addition, the business of providing orthodontic services is highly competitive
in each market in which the Company will operate. Each of the Founding
Affiliated Practices faces local competition from other orthodontists, general
dentists and pedodontists (dentists specializing in the care of children's
teeth), some of whom have more established practices. Dentists are not
restricted by law or any other governmental authority from providing orthodontic
services. Management believes the increase in recent years of dentists providing
orthodontic services has limited the growth of patient case starts performed by
orthodontists. There can be no assurance that the Company or the Affiliated
Practices will be able to compete effectively with their respective competitors,
that additional competitors will not enter their markets or that additional
competition will not have a material adverse effect on the Company.
    
EMPLOYEES
   
     At the date of this Prospectus, the Company employed ten persons and upon
consummation of the Acquisitions, the Company expects that it will have
approximately 284 employees of which approximately 15 will be employed at the
Company's headquarters and approximately 269 will be employed at the locations
of the Founding Affiliated Practices. None of the Company's employees are
represented by collective bargaining agreements. The Company has not experienced
any work stoppages as a result of labor disputes and the Company considers its
employee relations to be good.
    
LITIGATION AND INSURANCE
   
     The Affiliated Practices provide orthodontic services to the public and are
exposed to the risk of professional liability and other claims. Such claims, if
successful, could result in substantial damage awards to the claimants that may
exceed the limits of any applicable insurance coverage. Although the Company
does not control the practice of orthodontics by the Affiliated Practices, it
could be asserted that the Company should be held liable for malpractice of an
orthodontist employed by an Affiliated Practice. Each Affiliated Practice has
undertaken to comply with all applicable regulations and legal requirements, and
the Company maintains liability insurance for itself and it is anticipated that
the Company will be named as an additional insured party on the liability
insurance policies of the Affiliated Practices. The Founding Affiliated
Practices have agreed to maintain comprehensive professional liability
insurance, generally with limits of not less than $1,000,000 per claim and with
aggregate policy limits of not less than $3,000,000 per orthodontist and a
separate limit for each Affiliated Practice acceptable to Apple. There can be no
assurance, however, that a future claim or claims will not be successful or, if
successful, will not exceed the limits of available insurance coverage or that
such coverage will continue to be available at acceptable costs.

     On December 10, 1996, OCA filed a complaint in the United States District
Court for the Eastern District of Louisiana against Apple, Dr. Vondrak, John G.
Vondrak, P.C. and JGVAOI, alleging, among other things, misappropriation of
trade secrets and certain breaches of a confidentiality agreement executed by
Dr. Vondrak, on behalf of John Vondrak, P.C., in favor of OCA. While Apple is
not a party to the confidentiality agreement, OCA has alleged that the Company
should be bound by its terms as a result of the relationship between Dr. Vondrak
and Apple (specifically, OCA has alleged that Dr. Vondrak and Apple are alter
egos and, alternatively, that Dr. Vondrak was acting as Apple's agent when he
executed the confidentiality agreement). The Company intends to vigorously
defend against the claims made by OCA, which the Company believes are without
merit.
    
                                       27
<PAGE>
     The Company is not currently a party to any other claims, suits or
complaints relating to services and products provided by the Company or the
Founding Affiliated Practices, although there can be no assurances that such
claims will not be asserted against the Company in the future. The Company will
become subject to certain pending claims as the result of successor liability in
connection with the Acquisitions; however, it is the opinion of management that
the ultimate resolution of those claims will not have a material adverse effect
on the financial position or operating results of the Company.

     The Founding Affiliated Practices have maintained professional liability
insurance coverage on a claims-made basis. Such insurance provides coverage for
claims asserted when the policy is in effect regardless of when the events that
caused the claim occurred. The Company intends to acquire similar coverage after
the closing of the Acquisitions, since the Company, as a result of the
Acquisitions, will in some cases succeed to the liabilities of the Founding
Affiliated Practices. Therefore, claims may be asserted after the Acquisitions
against the Company for events that occurred prior to the Acquisitions.

GOVERNMENT REGULATION

     The orthodontic services industry is regulated extensively at both the
state and federal levels. Regulatory oversight includes, but is not limited to,
considerations of fee-splitting, corporate practice of orthodontics and state
insurance regulation.

  FEE-SPLITTING; CORPORATE PRACTICE OF ORTHODONTICS

     The laws of many states prohibit business corporations such as the Company
from engaging in the practice of orthodontics or employing orthodontists to
practice orthodontics and prohibit orthodontists from splitting fees with
non-orthodontists. The specific restrictions against the corporate practice of
orthodontics, as well as the interpretation of those restrictions by state
regulatory authorities, vary from state to state. The restrictions are generally
designed to prohibit a non-orthodontic entity (such as the Company) from
controlling the professional assets of an orthodontic practice (such as patient
records and payor contracts), employing orthodontists to practice orthodontics
(or, in certain states, employing dental hygienists or orthodontic assistants),
or controlling the content of an orthodontist's advertising or professional
practice. The Company does not control the practice of orthodontics or employ
orthodontists to practice orthodontics. Moreover, in states in which it is
prohibited, the Company does not employ orthodontic hygienists or orthodontic
assistants. The Company provides management services to the Affiliated
Practices, and believes that the management fees the Company charges for those
services are consistent with the laws and regulations of the jurisdictions in
which it operates. Therefore, the Company believes it would not be regarded as
"owner," "operator" or "manager" of the Affiliated Practices within the
meaning of those terms under the state orthodontic practice acts and believes
that its operations comply with the above-described laws to which it is subject.

     The laws of many states also prohibit orthodontists from sharing
professional fees with non-orthodontic entities. The Company believes that its
operations will not contravene any restriction on the corporate practice of
orthodontics and that the management fees it intends to charge for its services
are consistent with the laws and regulations of the jurisdictions in which it
will operate concerning fee-splitting. There can be no assurance, however, that
a review of the Company's business relationships by courts or regulatory
authorities will not result in determinations that could prohibit or otherwise
adversely affect the operations of the Company or that the regulatory
environment will not change, requiring the Company to reorganize or restrict its
existing or future operations. The laws regarding fee-splitting and the
corporate practice of orthodontics and their interpretation are enforced by
regulatory authorities with broad discretion. There can be no assurance that the
legality of the Company's business or its relationship with the Affiliated
Practices will not be successfully challenged or that the enforceability of the
provisions of any Service Agreement will not be limited.

     State dental boards do not generally interpret these prohibitions as
preventing a non-orthodontic entity from owning non-professional assets used by
an orthodontist in an orthodontic practice or providing management services to
an orthodontist for a fee provided that the following conditions are met: a
licensed dentist has complete control and custody over the professional assets;
the non-orthodontic entity does not

                                       28
<PAGE>
employ or control the orthodontists (or, in some states, orthodontic hygienists
or orthodontic assistants); all orthodontic services are provided by a licensed
dentist; licensed dentists have control over the manner in which orthodontic
care is provided and all decisions affecting the provision of orthodontic care.
State laws generally require that the amount of a management fee be reflective
of the fair market value of the services provided by the management company and
in certain states require that any management fee be a flat fee or cost-plus fee
based on the cost of services performed by the Company. In general, the state
orthodontic practice acts do not address or provide any restrictions concerning
the manner in which companies account for revenues from an orthodontic practice
subject to the above-noted restrictions relating to control over the
professional activities of the orthodontic practice, ownership of the
professional assets of an orthodontic practice and payments for management
services.

  STATE INSURANCE REGULATION

     Although the Company does not anticipate entering into managed care
contracts, there are certain regulatory risks associated with the Company's role
in negotiating and administering managed care contracts. The application of
state insurance laws to other than various types of fee for service arrangements
is an unsettled area of law and is subject to interpretation by regulators with
broad discretion. As the Company or the Affiliated Practices contract with
third-party payors, including self-insured plans, for certain non-fee for
service basis arrangements, the Company may become subject to state insurance
laws. Specifically, in some states, state insurance regulators may determine
that the Company or an Affiliated Practice is engaged in the business of
insurance because some of the managed care contracts to which an Affiliated
Practice may become a party may contain capitation features. The Company is
reviewing, and where appropriate modifying, the terms of certain of its
capitation contracts to reduce the likelihood that they could be characterized
as insurance contracts. In the event that the Company or an Affiliated Practice
is determined to be engaged in the business of insurance, it could be required
either to seek licensure as an insurance company or to change the form of the
relationships with third-party payors and, as a result the Company's revenues
may be adversely affected.

  HEALTH CARE REFORM PROPOSALS

     The United States Congress has considered various types of health care
reform, including comprehensive revisions to the current health care system. It
is uncertain what, if any, legislative proposals will be adopted in the future
or what actions federal or state legislatures or third-party payors may take in
anticipation of or in response to any health care reform proposals or
legislation. Health care reform legislation could have a material adverse effect
on the operations of the Company, and changes in the health care industry, such
as the growth of managed care organizations and provider networks, may result in
lower payment levels for the services of orthodontic practitioners and lower
profitability for Affiliated Practices.

BOARD OF DIRECTORS
   
     The Board of Directors of the Company currently is composed of three
directors. The Company intends to expand the Board of Directors shortly after
the Offering to add two additional directors, neither of whom will be affiliated
with the Company or its affiliates. The Board of Directors will be divided into
three classes with two directors in each class, with the term of one class
expiring at the annual meeting of stockholders in each year, commencing 1998. At
each annual meeting of stockholders, directors of the class the term of which
then expires will be elected by the holders of the Common Stock to succeed those
directors whose terms are expiring.
    
     On closing of the Offering, there will be three committees of the Board:
Audit, Compensation and Executive. The members of the Audit and Compensation
Committees will not be employees of the Company.

     Directors who are employees of the Company do not receive additional
compensation for serving as directors. Each director who is not an employee of
the Company will receive a fee of $2,000 for attendance at each Board of
Directors meeting and $1,000 for each committee meeting (unless held on the same
day as a Board of Directors meeting) and an initial grant of nonqualified
options to purchase 12,500 shares of Common Stock. See " -- 1996 Stock Option
Plan." All directors of the Company are reimbursed for out-of-pocket expenses
incurred in attending meetings of the Board of Directors or committees thereof,
and for other expenses incurred in their capacity as directors of the Company.

EXECUTIVE COMPENSATION
   
     Apple was incorporated in July 1996 and has not conducted any operations to
date other than in connection with the Offering and the Acquisitions. The
Company anticipates that during 1997 its most highly compensated executive
officers will be Dr. Vondrak and Messrs. Syverson, Harlan, Walton and Cook (the
"Named Executive Officers"), each of whom has entered or will enter into an
employment agreement providing for an annual salary of $180,000, $150,000,
$130,000, $130,000 and $120,000, respectively. See " -- Employment
Agreements."

     In addition to base salary, the Named Executive Officers through their
employment agreements are eligible for bonuses based on earnings performance of
the Company, and Mr. Walton is entitled to receive certain commissions upon the
consummation of future acquisitions. Bonuses are capped at 50% of base salary.

     Apple entered into agreements with Messrs. Syverson, Harlan and Cook
pursuant to which the Company sold to such officers 160,502 shares, 94,295
shares and 210,659 shares of Class B Stock, respectively, at a nominal purchase
price. Each holder of such shares is entitled to all rights of ownership of
Common Stock, including the right to vote and receive dividends, subject to
certain restrictions set forth in a subscription agreement entered into by the
Company and each such holder (each a "Subscription Agreement"). Each
Subscription Agreement provides that, until the restrictions affecting such
shares lapse, the holder may not sell, transfer, pledge or otherwise dispose of
the shares subject to the agreement. Each Subscription Agreement also provides
that, in the event of the termination of the employment of such holder (other
than as a result of termination without cause, death, disability or a change in
control of the Company), the Company shall have the right to repurchase any
shares with respect to which the restrictions imposed by the Subscription
Agreement have not lapsed at the price per share paid by the executive officer.
Each Subscription Agreement further provides that, in the event of a change in
control of the Company (defined to include, among other events, the acquisition
by any person or entity of 25% or more of the combined voting power of the
Company's then outstanding securities), the executive officer will be entitled
to put to the Company all shares purchased pursuant to such Subscription
Agreement that such person then owns (provided such shares are then subject to
resale restrictions under federal securities laws), and the Company will be
required to purchase all such shares, at a price equal to the fair market value
thereof at the time the change in control occurs.

     With respect to Messrs. Syverson and Harlan, the Subscription Agreements
provide that the restrictions shall lapse with respect to 50% of each holder's
shares upon consummation of the Offering and that the
    
                                       32
<PAGE>
   
restrictions on such holder's remaining shares will lapse on the first
anniversary of the consummation date of the Offering. The Subscription Agreement
between Apple and Mr. Cook provides that the restrictions will lapse immediately
upon issuance with respect to approximately 24% of his shares and that the
restrictions on the remaining shares shall lapse in two equal installments upon
consummation of the Offering and on the first anniversary of the consummation
date of the Offering.

     In January 1997, the Company granted options to purchase 135,000 shares,
100,000 shares, 90,000 shares and 179,295 shares of Common Stock to Dr. Vondrak,
Mr. Syverson, Mr. Harlan and Mr. Walton, respectively, under the Company's 1996
Stock Option Plan, exercisable at the initial public offering price per share
set forth on the cover page of this Prospectus. See "-- 1996 Stock Option
Plan."
    
EMPLOYMENT AGREEMENTS
   
     The Company has entered into employment agreements with Dr. Vondrak and
Messrs. Syverson, Harlan, Walton and Cook. The following summary of these
agreements, which will be effective on the closing of the Acquisitions and the
Offering, does not purport to be complete and is qualified by reference to such
agreements, copies of which have been filed as exhibits to the Registration
Statement of which this Prospectus is a part. Each of these agreements provides
for an annual base salary in an amount not less than the initial specified
amount and entitles the employee to participate in all the Company's
compensation plans (as defined) in which other executive officers of the Company
participate. Each of these agreements also has a continuous three-year term
subject to the right of the Company and the employee to terminate the employee's
employment at any time. If the employee's employment is terminated by the
Company without cause (as defined) or by the employee with good reason (as
defined), the employee will be entitled, during each of the years in the
three-year period beginning on the termination date, to (i) periodic payments
equal to his average annual cash compensation (as defined) from the Company,
including bonuses, if any, during the two years (or such shorter period of
employment) preceding the termination date, and (ii) continued participation in
all the Company's compensation plans (other than the granting of new awards
under the 1996 Stock Option Plan or any other performance-based plan). Except in
the case of a termination for cause, any stock options previously granted to the
employee under the Incentive Plan that have not been exercised and are
outstanding as of the time immediately prior to the date of his termination will
remain outstanding (and continue to become exercisable pursuant to their
respective terms) until exercised or the expiration of their term, whichever is
earlier. If a change of control (as defined) of the Company occurs, the employee
will be entitled to terminate his employment at any time during the 365-day
period following that change of control and receive a lump-sum payment equal to
three times his highest annual base salary under the agreement (plus such
amounts as may be necessary to hold the employee harmless from the consequences
of any resulting excise or other similar purpose tax relating to "parachute
payments" under the Internal Revenue Code of 1986, as amended (the "Code")).
Each employment agreement contains a covenant limiting the employee's right to
compete against the Company for a period of one year following termination of
employment.
    
     Each Founding Affiliated Practice will enter into an employment agreement
with its orthodontist employees. See "Business -- Orthodontist Employment
Agreements."

1996 STOCK OPTION PLAN
   
     In December 1996, the Board of Directors adopted, and the stockholders of
the Company approved, the 1996 Stock Option Plan. The purpose of the 1996 Stock
Option Plan is to provide employees, non-employee directors, advisors and
orthodontists with practice management contracts with the Company or a
subsidiary with additional incentives by increasing their proprietary interest
in the Company. The Company has reserved 1,000,000 shares of Common Stock for
use in connection with the 1996 Stock Option Plan (which includes 760,000 shares
subject to options previously granted). Beginning with the Company's first
fiscal quarter after the closing of this Offering and continuing each fiscal
quarter thereafter, the number of shares available for use in connection with
the 1996 Stock Option Plan will be the greater of 1,000,000 or 12% of the number
of shares of Common Stock outstanding on the last day of the preceding calendar
quarter.
    
                                       33
<PAGE>
     The 1996 Stock Option Plan provides for the grant of incentive stock
options ("ISOs"), as defined in Section 422 of the Code, and nonqualified
stock options (collectively, "Awards"). Following the consummation of the
Offering, the 1996 Stock Option Plan will be administered by the Compensation
Committee of the Board of Directors, which will be comprised of not less than
two members of the Board of Directors (the "Committee"). Prior to the
consummation of the Offering, the 1996 Stock Option Plan had been administered
by the Company's full Board of Directors. The Committee has, subject to the
terms of the 1996 Stock Option Plan, the sole authority to grant Awards under
the 1996 Stock Option Plan, to interpret the 1996 Stock Option Plan and to make
all other determinations necessary or advisable for the administration of the
1996 Stock Option Plan.
   
     All of the Company's employees, non-employee directors, advisors and
orthodontists with practice management contracts with the Company or a
subsidiary are eligible to receive Awards under the 1996 Stock Option Plan, but
only employees of the Company are eligible to receive ISOs. Awards will be
exercisable during the period specified in each option agreement and will
generally be exercisable in installments pursuant to a vesting schedule to be
designated by the Committee. Notwithstanding the provisions of any option
agreement, options will become immediately exercisable in the event of certain
events including certain merger or consolidation transactions and changes in
control of the Company. No option will remain exercisable later than ten years
after the date of grant (or five years from the date of grant in the case of
ISOs granted to holders of more than 10% of Common Stock).

     The exercise price for ISOs granted under the 1996 Stock Option Plan may be
no less than the fair market value of the Common Stock on the date of grant (or
110% of the fair market value in the case of ISOs granted to employees owning
more than 10% of the Common Stock). The per share exercise price for
nonqualified options granted under the 1996 Stock Option Plan will be in the
discretion of the Committee, but may not be less than the fair market value of a
share of Common Stock on the date of grant.
    
     There are generally no federal income tax consequences upon the grant of an
option under the 1996 Stock Option Plan. Upon exercise of a nonqualified option,
the optionee generally will recognize ordinary income in the amount equal to the
difference between the fair market value of the option shares at the time of
exercise and the exercise price, and the Company is generally entitled to a
corresponding tax deduction. When an optionee sells shares issued upon the
exercise of a non-qualified stock option, the optionee realizes short-term or
long-term capital gain or loss, depending on the length of the holding period,
but the Company is not entitled to any tax deduction in connection with such
sale.
   
     An optionee will not be subject to federal income taxation upon the
exercise of ISOs granted under the 1996 Stock Option Plan, and the Company will
not be entitled to a federal income tax deduction by reason of such exercise. A
sale of shares of Common Stock acquired upon exercise of an ISO that does not
occur within one year after the date of exercise or within two years after the
date of grant of the option generally will result in the recognition of
long-term capital gain or loss by the optionee in an amount equal to the
difference between the amount realized on the sale and the exercise price, and
the Company is not entitled to any tax deduction in connection therewith. If a
sale of shares of Common Stock acquired upon exercise of an ISO occurs within
one year from the date of exercise of the option or within two years from the
date of the option grant (a "disqualifying disposition"), the optionee
generally will recognize ordinary income equal to the lesser of (i) the excess
of the fair market value of the shares on the date of exercise of the options
over the exercise price or (ii) the excess of the amount realized on the sale of
the shares over the exercise price. Any amount realized on a disqualifying
disposition in excess of the amount treated as ordinary income will be long-term
or short-term capital gain, depending upon the length of time the shares were
held. The Company generally will be entitled to a tax deduction on a
disqualifying disposition corresponding to the amount of ordinary income
recognized by the optionee.

     The Company anticipates that upon the consummation of the Offering it will
have (i) outstanding options to purchase a total of approximately 760,000 shares
of Common Stock under the 1996 Stock Option Plan and (ii) options to purchase
240,000 additional shares available for grant under the 1996 Stock Option Plan.
    
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
   
     Prior to December 1996, the Company did not have a Compensation Committee,
and executive compensation has been set by the Company's Board of Directors.

                              CERTAIN TRANSACTIONS

ORGANIZATION OF THE COMPANY
   
     On October 11, 1996, the Company issued to TriCap, Dr. Vondrak, Mr.
Syverson and Mr. Cook (collectively, the "Founding Stockholders"), 1,685,274,
1,667,217, 160,502 and 210,659, respectively, shares of Class B Stock at an
aggregate purchase price of $4.20, $4.16, $0.40 and $0.53, respectively. On
December 9, 1996, the Company issued to Mr. Harlan 94,295 shares of Class B
Stock at an aggregate purchase price of $70.50. In connection with the
Acquisition of JGVAOI, Dr. Vondrak will receive approximately          shares of
Common Stock and $455,000, and will enter into a Service Agreement providing for
service fee payments to the Company. See "Business -- Service Agreements."
Additionally, TriCap has incurred $400,000 of expenses in connection with the
Acquisitions and the Offering, and has advanced to the Company $2.6 million to
fund transaction costs in exchange for the reimbursement of such expenses and
the repayment of such advances plus accrued interest (at the prime rate
announced by NationsBank of Texas, N.A. plus .25%) from the proceeds of the
Offering. The Company has used $230,000 of the funds advanced to it by TriCap to
reimburse JGVAOI for a portion of the organizational expenses of Apple incurred
by JGVAOI. The Company intends to reimburse JGVAOI an additional $70,000 from
the proceeds of the Offering to repay the remainder of such expenses. See "Use
of Proceeds."
    
AGREEMENTS WITH TRICAP
   
     TriCap Partners, an affiliate of TriCap co-owned by Mr. Sherrill, is the
exclusive financial advisor to Apple pursuant to a consulting agreement with an
initial term extending through the date of consummation of the first public
offering of Common Stock (or a security convertible into or exchangeable for
Common Stock) by the Company following the Offering. The consulting agreement
provides for, among other things, the payment by Apple to TriCap Partners of (i)
$500,000 upon consummation of the Offering and (ii) a warrant to purchase
229,500 shares of Common Stock with an exercise price per share equal to the
price to public per share set forth on the cover page of this Prospectus.

     Pursuant to a funding agreement between TriCap and Apple, TriCap has
advanced to Apple approximately $2.6 million to fund transaction costs in
connection with the Acquisitions and the Offering. These advances, which are
evidenced by the Convertible Notes, together with expenses incurred by TriCap on
behalf of the Company estimated at $400,000, will be repaid with proceeds from
the Offering. The funding agreement terminates pursuant to its terms upon
completion of the Offering. See "Use of Proceeds." In connection with this
agreement, Apple granted TriCap and Dr. Vondrak certain piggyback registration
rights. See "Shares Eligible For Future Sale."
    
COMPANY POLICY

     It is anticipated that future transactions with affiliates of the Company
will be minimal, will be approved by a majority of the disinterested members of
the Board of Directors and will be made on terms no less favorable to the
Company than could be obtained from unaffiliated third parties. The Company does
not intend to incur any further indebtedness to, or make any loans to, any of
its executive officers, directors or other affiliates.

                          DESCRIPTION OF CAPITAL STOCK

     The Company's authorized capital stock consists of 50,000,000 shares of
Class A Common Stock, par value $.01 per share, 4,106,852 shares of Class B
Common Stock, par value $0.01 per share, and 10,000,000 shares of preferred
stock, par value $.01 per share (the "Preferred Stock"). At February 28, 1997,
4,106,852 shares of Class B Stock were issued and outstanding and no shares of
Common Stock or preferred stock of the Company were issued and outstanding. The
following summary is qualified in its entirety by reference to the Certificate
of Incorporation, which is included as an exhibit to the Registration Statement
of which this Prospectus is a part.

COMMON STOCK AND CLASS B COMMON STOCK
   
     Holders of the Class B Stock are entitled to elect as a class one member of
the Board of Directors. The Common Stock and Class B Stock possess ordinary
voting rights and vote together as a single class for the election of all other
directors and in respect of all other corporate matters, and, in connection
therewith, holders of shares of Common Stock are entitled to one vote per share
and holders of shares of Class B Stock are entitled to three-tenths ( 3/10ths)
of a vote per share. The Common Stock and Class B Stock afford no cumulative
voting rights, and the holders of a majority of the shares voting for the
election of directors can elect all the directors if they choose to do so. The
Common Stock and Class B Stock carry no preemptive rights, are not convertible,
redeemable, assessable or entitled to the benefits of any sinking fund. The
holders of Common Stock and Class B Stock are entitled to dividends in such
amounts and at such times as may be declared by the Board of Directors out of
funds legally available therefor. The Company intends that, after completion of
the Offering, all future dividends, if any, declared on, or distributions with
respect to, its shares of Common Stock and Class B Stock will be paid on a pro
rata basis to the holders of such shares. See "Dividend Policy" for
information regarding the Company's dividend policy.

     Each share of Class B Stock will automatically convert to Common Stock on a
share-for-share basis (i) in the event of a disposition of such share of Class B
Stock by the holder thereof (excluding dispositions to such holder's
affiliates), (ii) in the event any person acquires beneficial ownership of 15%
or more of the outstanding shares of capital stock of the Company, (iii) in the
event any person offers to acquire 15% or more of the outstanding shares of
capital stock of the Company, (iv) in the event the holder of such share elects
to so convert at any time after the second anniversary of the date of this
Prospectus, (v) on the fifth anniversary of the date of this Prospectus or (vi)
in the event the holders of that number of shares of Common Stock and Class B
Stock, voting together as a single class, constituting a majority of the
outstanding voting power approve such conversion. In addition, the Company may
elect to convert any outstanding shares of Class B Stock into shares of Common
Stock in the event 80% or more of the outstanding shares of Class B Stock as of
the date of this Prospectus have previously been converted into shares of Common
Stock.
    
PREFERRED STOCK

     The Preferred Stock may be issued from time to time by the Board of
Directors as shares of one or more classes or series. Subject to the provisions
of the Certificate of Incorporation and limitations prescribed by law, the Board
of Directors is expressly authorized to adopt resolutions to issue the shares,
to fix the number of shares and to change the number of shares constituting any
series and to provide for or change the voting powers, designations, preferences
and relative, participating, optional or other special rights, qualifications,
limitations or restrictions thereof, including dividend rights (including
whether dividends are cumulative), dividend rates, terms of redemption
(including sinking fund provisions), redemption prices, conversion rights and
liquidation preferences of the shares constituting any class or series of the
Preferred Stock, in each case without any further action or vote by the holders
of Common Stock.

     Although the Company has no present intention to issue shares of Preferred
Stock, the issuance of shares of Preferred Stock, or the issuance of rights to
purchase such shares, could be used to discourage an unsolicited acquisition
proposal. For example, the issuance of a series of Preferred Stock might impede
a business combination by including class voting rights that would enable the
holders to block such a

                                       37
<PAGE>
transaction; or such issuance might facilitate a business combination by
including voting rights that would provide a required percentage vote of the
stockholders. In addition, under certain circumstances, the issuance of
Preferred Stock could adversely affect the voting power of the holders of the
Common Stock. Although the Board of Directors is required to make any
determination to issue such stock based on its judgment as to the best interests
of the stockholders of the Company, the Board of Directors could act in a manner
that would discourage an acquisition attempt or other transaction that some or a
majority of the stockholders might believe to be in their best interests or in
which stockholders might receive a premium for their stock over the then-market
price of such stock. The Board of Directors does not at present intend to seek
stockholder approval prior to any issuance of currently authorized stock, unless
otherwise required by law or the rules of any market on which the Company's
securities are traded.

STATUTORY BUSINESS COMBINATION PROVISION
   
     The Company is a Delaware corporation and is subject to Section 203 of the
DGCL. In general, Section 203 prevents an "interested stockholder" (defined
generally as a person owning 15% or more of a corporation's outstanding voting
stock) from engaging in a "business combination" (as defined) with a Delaware
corporation for three years following the time such person became an interested
stockholder unless (i) before such person became an interested stockholder, the
board of directors of the corporation approved the transaction in which the
interested stockholder became an interested stockholder or approved the business
combination, (ii) upon consummation of the transaction that resulted in the
stockholder's becoming an interested stockholder, the interested stockholder
owned at least 85% of the voting stock of the corporation outstanding at the
time the transaction commenced (excluding stock held by directors who are also
officers of the corporation and by employee stock plans that do not provide
employees with the rights to determine confidentially whether shares held
subject to the plan will be tendered in a tender or exchange offer) or (iii)
following the transaction in which such person became an interested stockholder,
the business combination was approved by the board of directors of the
corporation and authorized at a meeting of stockholders by the affirmative vote
of the holders of two thirds of the outstanding voting stock of the corporation
not owned by the interested stockholder. Under Section 203, the restrictions
described above also do not apply to certain business combinations proposed by
an interested stockholder following the announcement or notification of one of
certain extraordinary transactions involving the corporation and a person who
had not been an interested stockholder during the previous three years or who
became an interested stockholder with the approval of a majority of the
corporation's directors, if such extraordinary transaction is approved or not
opposed by a majority of the directors who were directors prior to any person's
becoming an interested stockholder during the previous three years or were
recommended for election or elected to succeed such directors by a majority of
such directors.
    
OTHER MATTERS
   
     Delaware law authorizes corporations to limit or eliminate the personal
liability of directors to corporations and their stockholders for monetary
damages for breach of a director's fiduciary duty of care. The duty of care
requires that, when acting on behalf of the corporation, directors must exercise
an informed business judgment based on all material information reasonably
available to them. Absent the limitations authorized by Delaware law, directors
are accountable to corporations and their stockholders for monetary damages for
conduct constituting gross negligence in the exercise of their duty of care.
Delaware law enables corporations to limit available relief to equitable
remedies such as injunction or rescission. The Certificate of Incorporation
limits the liability of directors of the Company to the Company or its
stockholders to the fullest extent permitted by Delaware law. Specifically,
directors of the Company will not be personally liable for monetary damages for
breach of a director's fiduciary duty as a director, except for liability (i)
for any breach of the director's duty of loyalty to the Company or its
stockholders, (ii) for acts or omissions not in good faith or which involve
intentional misconduct or a knowing violation of law, (iii) for unlawful
payments of dividends or unlawful stock repurchases or redemptions as provided
in Section 174 of the DGCL or (iv) for any transaction from which the director
derived an improper personal benefit.
    
                                       38
<PAGE>
     The inclusion of this provision in the Certificate of Incorporation may
have the effect of reducing the likelihood of derivative litigation against
directors and may discourage or deter stockholders or management from bringing a
lawsuit against directors for breach of their duty of care, even though such an
action, if successful, might otherwise have benefited the Company and its
stockholders. The Company's Bylaws provide indemnification to the Company's
officers and directors and certain other persons with respect to certain
matters, and the Company has entered into agreements with each of its directors
and executive officers providing for indemnification with respect to certain
matters.
   
     The Certificate of Incorporation provides that stockholders may act only at
an annual or special meeting of stockholders and may not act by written consent.
The Certificate of Incorporation and Bylaws provide that special meetings of the
stockholders can be called only by the Chairman of the Board, the President or a
majority of the Board of Directors.

     The Certificate of Incorporation provides that the Board of Directors shall
consist of three classes of directors serving for staggered terms. As a result,
it is currently contemplated that approximately one-third of the Company's Board
of Directors will be elected each year. The classified board provision could
prevent a party who acquires control of a majority of the outstanding voting
stock of the Company from obtaining control of the Board of Directors until the
second annual stockholders' meeting following the date the acquiror obtains the
controlling interest. See "Management -- Directors and Executive Officers and
Key Employees."
    
     The Certificate of Incorporation provides that the number of directors
shall be as determined by the Board of Directors from time to time, but shall
not be less than three. It also provides that directors may be removed only for
cause, and then only by the affirmative vote of the holders of at least a
majority of all outstanding voting stock entitled to vote. This provision, in
conjunction with the provisions of the Certificate of Incorporation authorizing
the Board of Directors to fill vacant directorships, will prevent stockholders
from removing incumbent directors without cause and filling the resulting
vacancies with their own nominees.

STOCKHOLDER PROPOSALS
   
     The Company's Bylaws contain provisions (i) requiring that advance notice
be delivered to the Company of any business to be brought by a stockholder
before an annual meeting of stockholders and (ii) establishing certain
procedures to be followed by stockholders in nominating persons for election to
the Board of Directors. Generally, such advance notice provisions provide that
written notice must be given to the Secretary of the Company by a stockholder
(i) in the event of business to be brought by a stockholder before an annual
meeting, not less than 90 days prior to the anniversary date of the immediately
preceding annual meeting of stockholders (with certain exceptions if the date of
the annual meeting is different by more than specified amounts from the
anniversary date), and (ii) in the event of nominations of persons for election
to the Board of Directors by any stockholder, (a) with respect to an election to
be held at the annual meeting of stockholders, not less than 90 days prior to
the anniversary date of the immediately preceding annual meeting of stockholders
(with certain exceptions if the date of the annual meeting is different by more
than specified amounts from the anniversary date), and (b) with respect to an
election to be held at a special meeting of stockholders for the election of
directors, not later than the close of business on the seventh day following the
day on which notice of the date of the special meeting was mailed to
stockholders or public disclosure of the date of the special meeting was made,
whichever first occurs. Such notice must set forth specific information
regarding such stockholder and such business or director nominee, as described
in the Company's Bylaws. The foregoing summary is qualified in its entirety by
reference to the Company's Bylaws, which are included as an exhibit to the
Registration Statement of which this Prospectus is a part.

                        SHARES ELIGIBLE FOR FUTURE SALE
   
     Upon consummation of the Acquisitions and the Offering, the Company will
have outstanding (i) _________ shares of Common Stock (_________ if the
Underwriters' over-allotment option is exercised in full) of which the
_________ shares sold in the Offering (_________ if the Underwriters'
over-allotment option is exercised in full) will be freely tradeable without
restriction or further registration under the Securities Act, except for those
held by "affiliates" (as defined in the Securities Act) of the Company, which
shares will be subject to the resale limitations of Rule 144 under the
Securities Act, and (ii) 4,106,852 shares of Class B Stock. The remaining
_________ shares of Common Stock and all of the outstanding shares of Class B
Stock are deemed "restricted securities" under Rule 144 in that they were
originally issued and sold by the Company in private transactions in reliance
upon exemptions under the Securities Act, and may be publicly sold only if
registered under the Securities Act or sold in accordance with an applicable
exemption from registration, such as those provided by Rule 144 promulgated
under the Securities Act as described below.

     In general, under Rule 144 as currently in effect, if a minimum of one year
has elapsed since the later of the date of acquisition of restricted securities
from the issuer or from an affiliate of the issuer, the acquirer or subsequent
holder would be entitled to sell within any three-month period a number of those
shares that does not exceed the greater of one percent of the number of shares
of such class of stock then outstanding or the average weekly trading volume of
the shares of such class of stock during the four calendar weeks preceding the
filing of a Form 144 with respect to such sale. Sales under Rule 144 are also
subject to certain manner of sale provisions and notice requirements and to the
availability of current public information about the issuer. In addition, if a
period of at least two years has elapsed since the later of the date of
acquisition of restricted securities from the issuer or from any affiliate of
the issuer, and the acquirer or subsequent holder thereof is deemed not to have
been an affiliate of the issuer of such restricted securities at any time during
the 90 days preceding a sale, such person would be entitled to sell such
restricted securities under Rule 144(k) without regard to the requirements
described above. Rule 144 does not require the same person to have held the
securities for the applicable periods. The foregoing summary of Rule 144 is not
intended to be a complete description thereof. The Commission has proposed
certain amendments to Rule 144 that would, among other things, eliminate the
manner of sale requirements and revise the notice provisions of that rule. The
SEC has also solicited comments on other possible changes to Rule 144, including
possible revisions to the one- and two-year holding periods and the volume
limitations referred to above.

     As of February 28, 1997, options to purchase an aggregate of approximately
760,000 shares of Common Stock were outstanding under the Company's 1996 Stock
Option Plan. See " Management -- 1996 Stock Option Plan." In general, pursuant
to Rule 701 under the Securities Act, any employee, officer or director of, or
consultant to, the Company who purchased his or her shares pursuant to a written
compensatory plan or contract is entitled to rely on the resale provisions of
Rule 701, which permit non-affiliates to sell such shares without compliance
with the public information, holding period, volume limitation or notice
provisions of Rule 144, and permit affiliates to sell such shares without
compliance with the holding period provisions of Rule 144, in each case
commencing 90 days after the date of this Prospectus. A total of 170,273 shares
of Common Stock will be eligible for resale pursuant to Rule 701 (upon exercise
of options) 90 days following the date of this Prospectus (although the holders
of those shares have agreed not to offer or sell any of those shares during the
180-Day Lockup Period). In addition, the Company intends to file a registration
statement covering the 829,727 additional shares issuable upon exercise of stock
options that may be granted in the future under the 1996 Stock Option Plan, in
which case such shares of Common Stock generally will be freely tradable by
non-affiliates in the public market without restriction under the Securities
Act.
    
     The Company, its executive officers and directors, TriCap and the persons
acquiring shares of Common Stock in connection with the Acquisitions have agreed
not to offer, sell, contract to sell, grant any option or other right for the
sale of, or otherwise dispose of any shares of Common Stock or any securities,
indebtedness or other rights exercisable for or convertible or exchangeable into
Common Stock owned or

                                       40
<PAGE>
   
acquired in the future in any manner prior to the expiration of 180 days after
the date of this Prospectus without the prior written consent of Bear, Stearns &
Co. Inc., except that the Company may issue, subject to certain conditions,
Common Stock in connection with acquisitions and may grant Awards (or Common
Stock upon exercise of Awards) under the 1996 Stock Option Plan. In addition,
the holders of the shares of Common Stock acquired in connection with the
Acquisitions have agreed with the Company that they generally will not sell,
transfer or otherwise dispose of any of their shares for one year following the
closing of the Offering. Substantially all the outstanding shares of Class B
Stock will become eligible for resale pursuant to Rule 144 in October 1997.

     In connection with the Acquisitions, the Company will enter into a
registration rights agreement with former stockholders of the Founding
Affiliated Practices (the "Registration Rights Agreement"), which will provide
certain registration rights with respect to the Common Stock issued to such
stockholders in the Acquisitions. The Registration Rights Agreement will provide
the holders of Common Stock subject to the agreement with the right in the event
the Company proposes to register under the Securities Act any Common Stock for
its own account or for the account of others at any time through November 2001,
subject to certain exceptions, to require the Company to include shares owned by
them in the registration. In addition, pursuant to a separate registration
rights agreement with TriCap and Dr. Vondrak, both TriCap and Dr. Vondrak have
the right, in the event the Company proposes to register under the Securities
Act any Common Stock for its own account or for the account of others at any
time through November 2001, subject to certain exceptions, to require the
Company to include shares owned by them in the registration.
    
     In the case of each registration rights agreement described above, the
Company is generally required to pay the costs associated with such an offering
other than underwriting discounts and commissions and transfer taxes
attributable to the shares sold on behalf of the selling stockholders. Each
registration rights agreement provides that the number of shares of Common Stock
that must be registered on behalf of the selling stockholders is subject to
limitation if the managing underwriter determines that market conditions require
a limitation. Under each agreement, the Company will indemnify the selling
stockholders thereunder, and such stockholders will indemnify the Company,
against certain liabilities in respect of any registration statement or offering
covered by the registration rights agreement.

     Prior to the Offering, there has been no established public market for the
Common Stock. No prediction can be made of the effect, if any, that sales of
shares under Rule 144, or otherwise, or the availability of shares for sale will
have on the market price of the Common Stock prevailing from time to time after
the Offering. The Company is unable to estimate the number of shares that may be
sold in the public market under Rule 144, or otherwise, because such amount will
depend on the trading volume in, and market price for, the Common Stock and
other factors. Nevertheless, sales of substantial amounts of shares in the
public market, or the perception that such sales could occur, could adversely
affect the market price of the Common Stock of the Company. See
"Underwriting."
   
     The Company intends to register 2,000,000 shares of Common Stock under the
Securities Act during the second quarter of 1997 for use in connection with
future acquisitions. These shares generally will be freely tradable after their
issuance by persons not affiliated with the Company unless the Company
contractually restricts their sale. The Company anticipates that the agreements
entered into in connection with its future acquisitions will contractually
restrict the resale of all or a portion of the shares issued in those
transactions for varying periods of time.

     Subject to the terms and conditions of the Underwriting Agreement among the
Company, Bear, Stearns & Co. Inc. and _________________ as the Representatives
of the Underwriters, each of the Underwriters named below has severally agreed
to purchase from the Company, and the Company has agreed to sell to the
Underwriters, the respective number of shares of Common Stock set forth opposite
its name below.

                                           NUMBER OF
              UNDERWRITERS                   SHARES

          Total.........................
                                          ============
    
   
     The Underwriting Agreement provides that the obligations of the several
Underwriters to purchase shares of Common Stock are subject to approval of
certain legal matters by counsel and to certain other conditions precedent. If
any of the shares of Common Stock are purchased by the Underwriters pursuant to
the Underwriting Agreement, all such shares of Common Stock (other than shares
of Common Stock covered by the over-allotment option described below) must be so
purchased.

     The Underwriters propose to offer the shares of Common Stock directly to
the public at the public offering price set forth on the cover page of this
Prospectus, and at such price less a concession not in excess of $____ per
share of Common Stock to certain other dealers who are members of the National
Association of Securities Dealers, Inc. The Underwriters may allow, and such
dealers may reallow, concessions not in excess of $____ per share to certain
other dealers. After the public offering, the offering price and other selling
terms may be changed by the Underwriters. The Company's Common Stock will be
quoted on the Nasdaq National Market.

     The Underwriters have been granted a 30-day over-allotment option to
purchase up to 312,500 additional shares of Common Stock of the Company
exercisable at the public offering price less the underwriting discount. If the
Underwriters exercise such over-allotment option, then each of the Underwriters
will have a firm commitment, subject to certain conditions, to purchase
approximately the same percentage thereof as the number of shares of Common
Stock to be purchased by it as shown in the above table bears to the ________
shares of Common Stock offered hereby. The Underwriters may exercise such option
only to cover over-allotments made in connection with the sale of the shares of
Common Stock offered hereby.

     The officers and directors of the Company and certain holders of the Common
Stock have agreed not to offer, sell, transfer, assign or otherwise dispose of,
any shares of Common Stock owned by them for a period of 180 days after the date
of the final Prospectus relating to the Offering, without the prior written
consent of Bear, Stearns & Co. Inc.

     The Company has agreed that it will not issue, sell or grant options to
purchase or otherwise dispose of any shares of its Common Stock or securities
convertible into or exchangeable for its Common Stock, except, subject to
certain conditions, with respect to acquisitions or pursuant to the 1996 Stock
Option Plan for a period of 180 days after the date of the final prospectus
relating to the Offering without the prior written consent of Bear, Stearns &
Co. Inc.

     The Underwriting Agreement provides that the Company will indemnify the
Underwriters and controlling persons, if any, against certain civil liabilities,
including liabilities under the Securities Act, or will contribute to payments
that the Underwriters or any such controlling persons may be required to make in
respect thereof.
    
                                       42
<PAGE>
   
     The Representatives of the Underwriters have informed the Company that the
Underwriters do not intend to confirm sales in excess of five percent of the
number of shares of Common Stock offered hereby to accounts over which they
exercise discretionary authority.

     Prior to the Offering, there was no public market for the Common Stock of
the Company. Consequently, the initial public offering price for the Common
Stock will be determined by negotiations between the Company and the
Representatives. The factors considered in making such determination will
include the prevailing market conditions, the financial condition and operating
history of the Company and the Affiliated Practices, their prospects and the
prospects for the orthodontic services industry in general, the management of
the Company and the market price of securities for companies in businesses
similar to that of the Company. There can be no assurance, however, that an
active or orderly trading market will develop for the Common Stock or that the
Common Stock will trade in the public market subsequent to the Offering at or
above the initial offering price.

     In connection with this Offering, the Underwriters may engage in
transactions that stabilize, maintain, or otherwise affect the price of the
Common Stock, including over-allotment and other stabilizing transactions, in
accordance with Rule 104 of Regulation M promulgated by the Commission. Such
transactions may be discontinued at any time.

     In connection with this Offering, certain Underwriters and selling group
members, if any, may engage in passive market making transactions in the Common
Stock on the Nasdaq National Market in accordance with Rule 103 of Regulation M
promulgated by the Commission. Passive market making consists of displaying bids
on the Nasdaq National Market limited by the prices of independent market makers
and effecting purchases limited by such prices and in response to order flow.
Rule 103 limits the amount of net purchases that each passive market maker can
make and the displayed size of the bid. Passive market making may stabilize the
market price of the Common Stock at a level above that which might otherwise
prevail and, if commenced, may be discontinued at any time.
    
                                 LEGAL MATTERS
   
     The validity of the shares of Common Stock offered hereby will be passed
upon for the Company by Jackson & Walker, L.L.P., Houston, Texas. Certain legal
matters in connection with the sale of the Common Stock offered hereby will be
passed upon for the Underwriters by Baker & Botts, L.L.P., Houston, Texas.

     After the stock split discussed in Note 2 to the Apple Orthodontix, Inc.'s
financial statements is effected, we expect to be in a position to render the
following audit report.

                                          Arthur Andersen LLP
                                          February 28, 1997

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Board of Directors and Stockholders of
Apple Orthodontix, Inc.:

     We have audited the accompanying balance sheet of Apple Orthodontix, Inc.,
a Delaware corporation, as of December 31, 1996, and the related statements of
operations, changes in stockholders' equity (deficit) and cash flows for the
period from inception, July 15, 1996, through December 31, 1996. These financial
statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audit.

     We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.

     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Apple Orthodontix, Inc., as
of December 31, 1996, and the results of its operations and its cash flows for
the period from inception, July 15, 1996, through December 31, 1996, in
conformity with generally accepted accounting principles.

                         NOTES TO FINANCIAL STATEMENTS

1.  BUSINESS AND ORGANIZATION:
   
     Apple Orthodontix, Inc. (Apple or the Company), was established as a
Delaware corporation on
July 15, 1996, for the purpose of creating an orthodontic practice management
company which will own the assets of and provide management services to
orthodontic practices (see Note 6). The Company's operations to date have
consisted primarily of seeking affiliations with orthodontists, negotiating to
acquire the assets of those professionals' practices and negotiating agreements
to provide management services to those practices (Acquisitions). Apple plans to
complete an initial public offering of its Class A common stock and
simultaneously exchange cash and shares of its Class A common stock for selected
assets and liabilities associated with 31 orthodontic practices (the Founding
Affiliated Practices). The completion of the Acquisitions, public offering and
entry by Apple into service agreements with the owners of the orthodontic
practices will mark the beginning of Apple's operations. The financial
statements have been prepared on the basis that the proposed transactions will
occur although no assurance can be made that the proposed transaction will be
completed.
    
2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

  DEFERRED ISSUANCE COSTS
   
     Substantially all costs incurred to date have been in conjunction with the
Acquisitions and the anticipated initial public offering (Offering) of the
Company's Class A common stock. All costs incurred in connection with those
efforts, excluding certain ongoing costs of the Company, have been capitalized
and will be charged against the proceeds of the initial public offering upon its
successful completion.
    
  ORGANIZATION COSTS

     Organization costs incurred in the formation of the Company are amortized
on a straight-line basis over a five-year period.

  STOCKHOLDERS' EQUITY (DEFICIT)
   
     On October 11, 1996, 3,884,155 shares of Class B common stock were issued
at a total price of $9.68. Management believes that the $.01 per share received
in consideration for those shares represented the fair value of the shares at
that date. On December 9, 1996, 222,697 additional shares were issued in
exchange for $166 of consideration. Management believes that the $3.00 per share
received in consideration for those shares represented the fair value of the
shares at that date. The shares issued through December 31, 1996 have been
restated to reflect the effect of a 4,013-for-one stock split. The Class B
common stock will be entitled to a three-tenths ( 3/10ths) of a vote per share.
The Class B common stock automatically converts to one vote per share in the
event of the disposition of the stock by the stockholder (excluding dispositions
to the holder's affiliates), any person offers to or acquires 15% or more of the
outstanding capital stock of the Company, any person acquires beneficial
ownership of 15% or more of the outstanding shares of capital stock of the
Company, the stockholder elects to convert at any time after the second
anniversary of the effective date of this Offering, the holders of that number
of shares of Class A common stock and Class B common stock, voting together as a
single class, with a majority of the outstanding voting power approve
conversion, or on the fifth anniversary of the effective date of this Offering.
In the event that 80 percent or more of the currently outstanding shares of
Class B common stock have been converted into shares of Class A common stock,
the Company may elect to convert the remaining outstanding shares of Class B
common shares into shares of Class A common stock. The Class A common stock to
be issued to the Founding Affiliated Practices and in the Offering will be
entitled to one vote per share.

     The shares used in calculating net loss per share include all shares of
capital stock outstanding as of February 28, 1997 and the additional shares that
would be outstanding if all options that were issued prior to the Offering were
exercised and the proceeds used to repurchase shares at an assumed offering
price of $12 per share.

                  NOTES TO FINANCIAL STATEMENTS -- (CONTINUED)

  STOCK OPTION PLAN
   
     In December 1996 the board of directors of the Company adopted the 1996
Stock Option Plan (Plan). Employees, non-employee directors and advisors are
eligible to receive awards under the Plan; only employees of the Company are
eligible to receive incentive stock options. The aggregate number of options to
purchase shares of common stock that may granted under the Plan is the greater
of 1,000,000 or 12% of the number of shares of Class A common stock outstanding
on the last day of the preceding calendar quarter. As of December 31, 1996, no
options had been granted under the Plan. The Company anticipates that upon or
shortly after the consummation of its Offering that it will grant options to
purchase approximately 798,000 shares of common stock under the Plan. All of
these options will be at the Offering price except for 20,000 options that were
granted in January 1997 at $3.00 per option, which equaled the fair value of the
common stock of the Company at that date. The Company will account for options
issued to employees and non-employee directors under the Plan in accordance with
APB Opinion No. 25, and accordingly no compensation cost will be recognized. The
Company will provide the pro forma disclosure of net earnings per share in the
notes to the financial statements as if the fair value-based method of
accounting had been applied to awards as required by Statement of Financial
Accounting Standard No. 123, "Accounting for Stock-Based Compensation."
    
  INCOME TAXES

     As reflected in the accompanying statement of operations, the Company
incurred a loss from operations during the period from inception, July 15, 1996,
through December 31, 1996. Due to the limited operations of the Company since
its inception and the pending Offering, a valuation allowance has been recorded
to fully reserve for the deferred tax benefits generated by these net operating
losses. There is no significant difference in the tax and book bases of the
Company's assets or liabilities that would give rise to deferred tax balances.

  USE OF ESTIMATES
   
     The preparation of financial statements in conformity with generally
accepted accounting principles requires the use of estimates and assumptions by
management in determining the reported amounts of liabilities and disclosures of
contingent assets and liabilities at the date of the financial statements and
the reported amounts of expenses during the reporting period. Actual results
could differ from those estimates.
    
3.  FINANCING PROVIDED BY VENTURE CAPITAL INVESTORS:
   
     On November 14, 1996, the Company entered into an agreement with TriCap
Funding I, L.L.C. (TriCap), whereby TriCap agreed to provide $3,000,000 to
finance costs related to the Offering. As of December 31, 1996, the Company had
borrowed $515,000 under this agreement. The $3,000,000, to the extent expended,
will be repaid out of proceeds from the Offering, including interest at a rate
of prime plus .25 percent. The Company also entered into an agreement on such
date with TriCap Partners, L.L.C. (TriCap Partners) that extends through the
date of the consummation of the first public offering of Common Stock (or a
security convertible or exchangeable for Common Stock) by the Company following
the Offering. This agreement provides for (a) the payment by Apple to TriCap
Partners of approximately $500,000 upon consummation of the Offering, and (b)
the issuance to TriCap Partners of a warrant to purchase 229,500 shares of
Common Stock at an exercise price per share equal to the initial offering price
to public per share.
    
4.  RELATED PARTY:
   
     The practice of a founding stockholder of the Company, John G. Vondrak,
D.D.S., has paid for certain costs and expenses on behalf of the Company. Such
payments, net of reimbursement in conjunction with the
    
                                      F-8

financing, have been reflected as amounts due to a Founding Affiliated Practice
in the accompanying balance sheet and will be repaid with proceeds from the
planned Offering.
    
5.  LITIGATION:
   
     On December 10, 1996, Orthodontic Centers of America (OCA) filed a
complaint against Apple, Dr. Vondrak and his practice, alleging misappropriation
of trade secrets and breach of a confidentiality agreement executed by Dr.
Vondrak with OCA. The Company plans to vigorously defend itself in this matter
and does not believe that the results of these proceedings will have a material
adverse effect on the Company's operating results or financial position.
    
6.  PLANNED ACQUISITIONS OF FOUNDING AFFILIATED PRACTICES:
   
     Apple plans to complete, through a series of mergers and asset purchases,
the acquisition of certain assets and assumption of certain liabilities of the
Founding Affiliated Practices (the Acquisitions) concurrently with an initial
public offering of shares of its Class A common stock. The Founding Affiliated
Practices will receive Class A common stock and cash as consideration in the
Acquisitions. In connection with the Acquisitions, the selling orthodontists
will create new professional corporations, professional associations or other
entities (collectively, the New PCs) that will enter into 20-year service
agreements with Apple. Additionally, those orthodontists will enter into
employment and noncompete agreements with the New PCs.
    
     The Company will not employ orthodontists or control the practice of
orthodontics by the orthodontists employed by the New PCs. As Apple will not be
acquiring the future patient revenues earned by the New PCs, the Acquisitions
are not deemed to be business combinations. In accordance with the Securities
and Exchange Commission's Staff Accounting Bulletin (SAB) No. 48, "Transfers of
Nonmonetary Assets by Promoters or Shareholders," the acquired nonmonetary
assets and assumed liabilities will be accounted for at the historical cost
basis of the Founding Affiliated Practices. Any monetary assets included in the
Acquisitions will be recorded at fair value. The resulting value of the net
assets acquired by Apple will be recorded as the value of the stock
consideration tendered. Cash consideration paid to selling orthodontists in
conjunction with the Acquisitions will be reflected as a dividend paid by Apple.

     The selling orthodontists will generally retain the long-term debt
obligations of their respective practices. Capital lease obligations will be
assumed by the Company. In certain cases, Apple has agreed to refinance debt
retained by the selling orthodontists.

     The combined detail of the Founding Affiliated Practices' assets to be
acquired and liabilities to be assumed is as follows:

COMBINED PRESENTATION OF ASSETS TO BE ACQUIRED AND LIABILITIES ASSUMED FROM THE
             FOUNDING AFFILIATED PRACTICES AS OF DECEMBER 31, 1996
   
Cash and cash equivalents............  $  1,177,000

Accounts payable and accrued
  liabilities........................    (1,627,000)
Long-term portion of capital lease
  obligations........................      (312,000)
    

     The management service revenues that will be earned by Apple subsequent to
the Acquisitions and execution of the service agreements are based on various
arrangements. In general, the resulting fee will be substantially based on the
patient revenues and cash collections of the New PCs and the operating expenses
assumed by Apple. Apple's standard form of service agreement (the Standard
Contract) will be applied to

all practices operating in locations where it is not prohibited by law or
governmental regulation. In those instances where the standard contract may not
be permitted, an alternative form of agreement (the Alternative Contract) will
be used.

     Patient revenues are derived from orthodontic care provided to patients
under contract terms agreed to by the patient or other responsible parties. The
contracts vary by practice and by patient, and service often extends over an
eighteen month to six-year period. Revenue is recognized on a
percentage-of-completion basis, with approximately 24 percent being recognized
at the time of initial treatment. The balance of the contract revenue is
realized pro rata each month over the remaining contract period. The 24 percent
estimated cost at the initial treatment date is consistent with industry
standards and includes the estimated costs of diagnosis, treatment plan
development, initial treatment by orthodontic personnel, orthodontic supplies
and associated administrative services.

     The difference in the timing of the recognition of patient revenues and
cash collections results in (i) unbilled receivables in instances where
recognition of revenues precedes the patient's payment plan and (ii) patient
prepayments when payments are made on a more accelerated basis than revenues are
earned. The following table presents the combined uncollected patient
receivables unbilled patient receivables and patient prepayments of the Founding
Affiliated Practices. These amounts are not receivables of the Company, but the
net position of these receivables will be acquired as part of the Acquisitions
and in future periods each New PC will provide the Company with a security
interest in the receivables of the New PC.

     Subsequent to the Acquisitions, the operating expenses of the Founding

the related services to the New PCs. The combined historical expenses of the
Founding Affiliated Practices for the year ended December 31, 1996 that will be

     The combined historical financial information of the Founding Affiliated
Practices presented herein is not related to the financial position or results
of operations of Apple. This information is presented solely for the purpose of
providing disclosures to potential investors regarding the group of entities
with which Apple will be contracting to provide future services. The Founding
Affiliated Practices' financial information is presented on a combined basis to
assist in an understanding of their relationship to the pro forma financial
statements included elsewhere in this registration statement and due to the fact
that their service agreements with the Company will be signed contingent on the
single common event of the completion of the Offering. The Founding Affiliated
Practices were not operated under common control or management during the fiscal
year ended December 31, 1996.

             UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS

     The following unaudited pro forma consolidated financial statements include
the unaudited pro forma consolidated balance sheet of Apple Orthodontix, Inc.
(Apple or the Company) as of December 31, 1996 and the unaudited pro forma
consolidated statement of operations of the Company for the year ended December
31, 1996.
   
     The unaudited pro forma consolidated financial statements have been
prepared as if (a) the acquisitions by Apple, which include the acquisition of
certain assets and assumption of certain liabilities associated with 31
orthodontic practices (the Founding Affiliated Practices) for consideration
consisting of a combination of cash and shares of Class A common stock of the
Company, and the execution of agreements to provide management services to the
Founding Affiliated Practices (collectively, the Acquisitions) and (b) the
initial public offering of the Company's common stock (the Offering), had been
completed. The accompanying unaudited pro forma consolidated balance sheet as of
December 31, 1996 gives effect to the Acquisitions and Offering as if such
transactions had occurred on December 31, 1996. The accompanying unaudited pro
forma consolidated statement of operations for the year ended December 31, 1996
assumes the Company had completed the transactions on January 1, 1996.

     The Company will not employ orthodontists or control the practice of
orthodontics by the orthodontists. As Apple will not be acquiring the future
patient revenues earned by the Founding Affiliated Practices, the Acquisitions
are not deemed to be business combinations. In accordance with the Securities
and Exchange Commission's Staff Accounting Bulletin No. 48, "Transfers of
Nonmonetary Assets by Promoters or Shareholders," the Acquisitions will be
accounted for at the historical cost basis with the shares of Class A common
stock to be issued in those transactions being valued at the historical cost of
the nonmonetary assets acquired net of liabilities assumed. The cash
consideration will be reflected as a dividend by Apple to the owners of the
Founding Affiliated Practices.

     The unaudited pro forma consolidated financial statements have been
prepared by the Company based on the audited historical financial statements of
Apple included elsewhere in this Prospectus, including the audited combined
financial information of the Founding Affiliated Practices included in the notes
to those financial statements, and assumptions deemed appropriate by the
Company. These unaudited pro forma consolidated financial statements may not be
indicative of actual results that might have been obtained if the transactions
had occurred on the dates indicated or which may be realized in the future.
Neither expected benefits and cost reductions anticipated by the Company nor all
costs associated with the Company's present or future cost structure have been
reflected in the accompanying unaudited pro forma consolidated financial
statements. The unaudited pro forma consolidated statement of operations
includes the financial results of Apple for the period from inception, July 15,
1996, through December 31, 1996. Additionally, certain of the Founding
Affiliated Practices made acquisitions or experienced departures of owner
orthodontists or employee orthodontists during the year ended December 31, 1996;
the Company does not consider the net effect of these changes to be significant
for the purposes of these unaudited pro forma consolidated financial statements.

UNAUDITED PRO FORMA CONSOLIDATED BALANCE SHEET ADJUSTMENTS
   
     The accompanying unaudited pro forma consolidated balance sheet as of
December 31, 1996 gives effect to the Acquisitions and the Offering as if those
transactions had occurred on December 31, 1996. The unaudited pro forma
consolidated balance sheet does not represent the historical or future financial
position of Apple.
    
     (A)  Reflects the accrual of estimated offering costs to be incurred
subsequent to December 31, 1996, in conjunction with the Offering to a total of
$5,000.
   
     (B)  Reflects the issuance of 2,083,333 shares of Class A common stock by
the Company in the Offering at an assumed initial public offering price of
$12.00 per share, net of underwriters' commissions of $1,750 and the
reclassification of deferred issuance costs of $6,150 (including estimated
additional fees at closing of $1,150) in total against the Offering proceeds.
The resulting net proceeds of $18,200 are reflected as Class A common stock, par
value of $.01 per share, totaling $21, with the remaining amount recorded as
additional paid-in capital of $17,079.

     (C)  Reflects completion of the Acquisitions, which will involve (1) the
issuance of 2,143,148 shares of Class A Common Stock based on the assumed
initial public offering price of $12 per share and (2) the declaration of an
$6,429 dividend, taken together, as consideration in the Acquisitions for net
assets with a historical net book value as of December 31, 1996 of $2,638
consisting of certain assets and certain liabilities of the Founding Affiliated
Practices.
    
     The assets and liabilities of the Founding Affiliated Practices being
acquired and reflected herein are as follows:
   
Cash and cash equivalents............  $   1,177
Patient receivables, net of
  allowances and patient prepayments.        866

                                       =========
    
     Net assets acquired does not include certain long-term debt of the Founding
Affiliated Practices which will be assumed by the owner orthodontists at or
prior to the Acquisitions.

     This transaction would produce a pro forma deferred tax asset of
approximately $304 which has been fully reserved in these pro forma statements
as the realizability of such asset cannot be determined.

     (D)  Represents property, equipment and improvements separately owned by a
selling orthodontist at December 31, 1996 related to new offices opening in 1997
that will also be acquired as an additional part of the Acquisitions in note
(C).

     (E)  Reflects the estimated amount of financing Apple will provide to the
selling orthodontists to refinance debt which was outstanding and recorded by
the Founding Affiliated Practices as of December 31, 1996 resulting in notes
receivable from the selling orthodontists of $947 offset by approximately $100
of debt which Apple has agreed to assume in conjunction with the Acquisitions.

UNAUDITED PRO FORMA CONSOLIDATED STATEMENT OF OPERATIONS ADJUSTMENTS

     The accompanying unaudited pro forma consolidated statement of operations
for the year ended December 31, 1996 assumes the Company had completed the
Acquisitions and the Offering on January 1, 1996. The pro forma adjustments are
based on the historical financial results of the Founding Affiliated Practices.
This statement does not represent the historical or future results of operations
of the Company.

     (AA)  Represents estimated management service revenues of Apple calculated
in accordance with the management service agreements anticipated to be entered
into with the Founding Affiliated Practices, as applied to the historical
operating results of the individual Founding Affiliated Practices for the year
ended December 31, 1996.
   
     The management service fees earned by the Company will be in accordance
with two general types of service agreements -- the standard form of the service
agreement (Standard Contract) and the alternative form of the service agreement
(the Alternative Contract). The determination of which agreement will be used
for a practice depends on the laws relating to the corporate practice of
dentistry and fee splitting in the state or states in which that practice
operates. The Standard Contract calls for a calculation of the monthly service
fee based on the total revenues earned by the New PCs, which is defined by the
agreement to represent 24% of the total contract value in the initial month of a
patient's treatment with the remainder of the contract balance earned evenly
over the balance of the contract term. From total revenues, the orthodontists
retain a set percentage of the New PC's cash collections. There are adjustments
to the service fee designed to both provide incentives for the orthodontists to
provide efficient patient treatment and to increase the number of patients
treated, as well as to ensure that the orthodontists retain a minimum amount for
payment of their compensation from their respective New PCs on a monthly basis.
The Alternative Contract is currently offered in California. It is a cost plus
fee arrangement, whereby the service fee includes the reimbursement of defined
expenses incurred by Apple in the course of providing services to the New PC
plus a percentage of revenues.

     The pro forma management service fee for practices that have agreed to the
Standard Contract is based on the accrual basis revenues of the Founding
Affiliated Practices ($19,699) less an amount based on the cash collections of
the practices ($6,547) appropriately adjusted for various provisions of the
service fee agreement (taken together, a net increase of $1,327). The resulting
pro forma management service fee for the year ended December 31, 1996 is
$14,479.

     The pro forma management service fee for practices that have agreed to the
Alternative Contract represents a percentage of revenues ($724) and
reimbursement of the operating expenses of those practices ($2,935). The total
pro forma management service revenues would have been:
    
Practices participating under the
  Standard Contract.....................  $  14,479
Practices participating under the
  Alternative Contract..................      3,659
                                          ---------
     Total pro forma management service
      revenues..........................  $  18,138

 NOTES TO UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL STATEMENTS -- (CONTINUED)

     The revenues and cash collections used to calculate the pro forma
management service revenues have not been adjusted for the pro forma effect of
acquisitions and dispositions made by the Founding Affiliated Practices during
the year ended December 31, 1996. Management does not believe that such
adjustments would have a material impact on the calculation of these pro forma
calculations.

     (BB)  Represents an adjustment to reflect certain historical costs of the
Founding Affiliated Practices that will be incurred by the Company in order to
fulfill the Company's obligations under the service agreements with the Founding
Affiliated Practices.

     (CC)  Reflects interest expense attributable to capital lease obligations
expected to be assumed by Apple in connection with the Acquisitions.

     (DD)  Reflects interest income on the notes receivable from orthodontists
related to the refinancing of their long term obligations at a rate of prime
plus one percent less increased interest expense related to debt of the
practices' that the Company has agreed to assume.

     (EE)  Reflects federal and state income taxes the Company would have
incurred on pro forma income before taxes at an assumed income tax rate of 38
percent.

     (FF)  The number of shares used in the pro forma net income per share
calculation are determined as follows:

Estimated outstanding Apple shares after
  the Acquisitions and Offering.........    8,333,333
Net shares that would be outstanding if
  outstanding options were exercised and
  the proceeds were used to repurchase

ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.

  DELAWARE GENERAL CORPORATION LAW

     Section 145(a) of the General Corporation Law of the State of Delaware (the
"DGCL") provides that a corporation may indemnify any person who was or is a
party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding, whether civil, criminal, administrative or
investigative (other than an action by or in the right of the corporation) by
reason of the fact that he is or was a director, officer, employee or agent of
the corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another corporation, partnership, joint
venture, trust or other enterprise, against expenses (including attorney's
fees), judgements, fines and amounts paid in settlement actually and reasonably
incurred by him in connection with such action, suit or proceeding if he acted
in good faith and in a manner he reasonably believed to be in or not opposed to
the best interests of the corporation, and, with respect to any criminal action
or proceeding, had no reasonable cause to believe his conduct was unlawful. The
termination of any action, suit or proceeding by judgment, order, settlement,
conviction, or upon a plea of NOLO CONTENDERE or its equivalent, shall not, of
itself, create a presumption that the person did not act in good faith and in a
manner which he reasonably believed to be in or not opposed to the best
interests of the corporation, and, with respect to any criminal action or
proceeding, had reasonable cause to believe that his conduct was unlawful.

     Section 145(b) of the DGCL states that a corporation may indemnify any
person who was or is a party or is threatened to be made a party to any
threatened, pending or completed action or suit by or in the right of the
corporation to procure a judgment in its favor by reason of the fact that he is
or was a director, officer, employee or agent of the corporation, or is or was
serving at the request or agent of another corporation, partnership, joint
venture, trust or other enterprise against expenses (including attorney's fees)
actually and reasonably incurred by him in connection with the defense or
settlement of such action or suit if he acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
corporation and except that no indemnification shall be made in respect of any
claim, issue or matter as to which such person shall have been adjudged to be
liable to the corporation unless and only to the extent that the Court of
Chancery or the court in which such action or suit was brought shall determine
upon

                                      II-1
<PAGE>
application that, despite the adjudication of liability but in view of all the
circumstances of the case, such person is fairly and reasonably entitled to
indemnity for such expenses which the Court of Chancery or such other court
shall deem proper.

     Section 145(c) of the DGCL provides that to the extent that a director,
officer, employee or agent of a corporation has been successful on the merits or
otherwise in defense of any action, suit or proceeding referred to in
subsections (a) and (b) of Section 145, or in defense of any claim, issue or
matter therein, he shall be indemnified against expenses (including attorney's
fees) actually and reasonably incurred by him in connection therewith.

     Section 145(d) of the DGCL states that any indemnification under
subsections (a) and (b) of Section 145 (unless ordered by a court) shall be made
by the corporation only as authorized in the specific case upon a determination
that indemnification of the director, officer, employee or agent is proper in
the circumstances because he has met the applicable standard of conduct set
forth in subsections (a) and (b). Such determination shall be made (1) by the
board of directors by a majority vote of a quorum consisting of directors who
were not parties to such action, suit or proceeding, or (2) if such a quorum is
not obtainable, or, even if obtainable, a quorum of disinterested directors so
directs, by independent legal counsel in a written opinion, or (3) by the
stockholders.

     Section 145(e) of the DGCL provides that expenses (including attorneys'
fees) incurred by an officer or director in defending any civil, criminal,
administrative or investigative action, suit or proceeding may be paid by the
corporation in advance of the final disposition of such action, suit or
proceeding upon receipt of an undertaking by or on behalf of such director or
officer to repay such amount if it shall ultimately be determined that he is not
entitled to be indemnified by the corporation as authorized in Section 145. Such
expenses (including attorneys' fees) incurred by other employees and agents may
be so paid upon such terms and conditions, if any, as the board of directors
deems appropriate.

     Section 145(f) of the DGCL states that the indemnification and advancement
of expenses provided by, or granted pursuant to, the other subsections of
Section 145 shall not be deemed exclusive of any other rights to which those
seeking indemnification or advancement of expenses may be entitled under any
bylaw, agreement, vote of stockholders or disinterested directors or otherwise,
both as to action in his official capacity and as to action in another capacity
while holding such office.

     Section 145(g) of the DGCL provides that a corporation shall have the power
to purchase and maintain insurance on behalf of any person who is or was a
director, officer, employee or agent of the corporation, or is or was serving at
the request of the corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
against any liability asserted against him and incurred by him in any such
capacity, or arising out of his status as such, whether or not the corporation
would have the power to indemnify him against such liability under the
provisions of Section 145.

     Section 145(j) of the DGCL states that the indemnification and advancement
of expenses provided by, or granted pursuant to, Section 145 shall, unless
otherwise provided when authorized or ratified, continue as to a person who has
ceased to be a director, officer, employee or agent, and shall inure to the
benefit of the heirs, executors and administrators of such a person.

CERTIFICATE OF INCORPORATION

     The Restated Certificate of Incorporation of the Company provides that a
director of the Company shall not be personally liable to the Company or its
stockholders for monetary damages for breach of fiduciary duty as a director,
except for liability (i) for any breach of the director's duty of loyalty to the
Company or its stockholders, (ii) for acts or omissions not in good faith or
which involve intentional misconduct or a knowing violation of law, (iii) under
Section 174 of the DGCL or (iv) for any transaction from which the director
derived an improper personal benefit. If the DGCL is amended to authorize the
further elimination or limitation of the liability of directors, then the
liability of a director of the Company, in addition to the limitation on
personal liability described above, shall be limited to the fullest extent
permitted by the amended DGCL. Further, any repeal or modification of such
provision of the Restated Certificate of Incorporation by the stockholders of
the Company shall be prospective only, and shall not

                                      II-2
<PAGE>
adversely affect any limitation on the personal liability of a director of the
Company existing at the time of such repeal or modification.

BYLAWS

     The Bylaws of the Company provide that the Company will indemnify and hold
harmless any director or officer of the Company to the fullest extent permitted
by applicable law, as in effect as of the date of the adoption of the Bylaws or
to such greater extent as applicable law may thereafter permit, from and against
all losses, liabilities, claims, damages, judgments, penalties, fines, amounts
paid in settlement and expenses (including attorneys' fees) whatsoever arising
out of any event or occurrence related to the fact that such person is or was a
director or officer of the Company and further provide that the Company may, but
is not required to, indemnify and hold harmless any employee or agent of the
Company or a director, officer, employee or agent of any other corporation,
partnership, joint venture, trust, employee benefit plan or other enterprise who
is or was serving in such capacity at the written request of the Company;
provided, however, that the Company is only required to indemnify persons
serving as directors, officers, employees or agents of the Company for the
expenses incurred in a proceeding if such person is a party to and is
successful, on the merits or otherwise, in such proceeding, or if unsuccessful
in the proceeding, but successful as to a matter in such proceeding, the
expenses attributable to such matter and provided further that the Company may,
but is not required to, indemnify such persons who are serving as a director,
officer, employee or agent of any other corporation, partnership, joint venture,
trust, employee benefit plan or other enterprise at the written request of the
Company for the expenses incurred in a proceeding if such person is a party to
and is successful, on the merits or otherwise, in such proceeding. The Bylaws
further provide that, in the event of any threatened, or pending action, suit or
proceeding in which any of the persons referred to above is a party or is
involved and that may give rise to a right of indemnification under the Bylaws,
following written request by such person, the Company will promptly pay to such
person amounts to cover expenses reasonably incurred by such person in such
proceeding in advance of its final disposition upon the receipt by the Company
of (i) a written undertaking executed by or on behalf of such person providing
that such person will repay the advance if it is ultimately determined that such
person is not entitled to be indemnified by the Company as provided in the
Bylaws and (ii) satisfactory evidence as to the amount of such expenses.

ITEM 15.  RECENT SALES OF UNREGISTERED SECURITIES.

     The following information relates to securities of the Company issued or

D.D.S., W. Daniel Cook, Robert J. Syverson, Roxanne Robertson, Wm. Randol
Womack, D.D.S., Duncan Y. Brown, D.D.S., Wanda Rose and Stephen DeOrlow,
Trustee, respectively, the founders of the Company, for $0.01 per share. On

Stock to Michael W. Harlan, LeeAnn Peniche, Orthodontic Investors of Texas II,
Inc. and Allan Benson, respectively, for $3.00 per share. Such issuances were

                                      II-3
<PAGE>
     In March 1997, each outstanding share of Common Stock was reclassified into
4,012.5569 shares of Class B Stock (the "Stock Split"). The Stock Split was
exempt from the registration requirements of the Securities Act as it did not
involve a "sale," as defined in Section 2(3) of the Securities Act.

     Simultaneously with the completion of this Offering, the Company will issue
2,143,148 shares of Common Stock in connection with the acquisition of the

ITEM 17.  UNDERTAKINGS.

     The undersigned registrant hereby undertakes as follows:

     (1)  To provide to the Underwriters at the closing specified in the
Underwriting Agreement certificates in such denominations and registered in such
names as required by the Underwriters to permit prompt delivery to each
purchaser.

     (2)  Insofar as indemnification for liabilities arising under the
Securities Act may be permitted to directors, officers and controlling persons
of the registrant pursuant to the provisions described in Item 14, or otherwise,
the registrant has been advised that in the opinion of the Commission such
indemnification is

                                      II-4
<PAGE>
against public policy as expressed in the Securities Act and is, therefore,
unenforceable. In the event that a claim for indemnification against such
liabilities (other than the payments by the registrant of expenses incurred or
paid by a director, officer or controlling person of the registrant in the
successful defense of any action, suit or proceeding) is asserted by such
director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter
has been settled by controlling precedent, submit to a court of appropriate
jurisdiction the question whether such indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
adjudication of such issue.

     (3)  That, for the purposes of determining any liability under the
Securities Act, the information omitted from the form of prospectus filed as
part of this registration statement in reliance upon Rule 430A and contained in
a form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4)
or 497(h) under the Securities Act shall be deemed to be part of this
registration statement as of the time it was declared effective.

     (4)  That, for the purpose of determining any liability under the
Securities Act, each post-effective amendment that contains a form of prospectus
shall be deemed to be a new registration statement relating to the securities
offered therein, and the offering of such securities at that time shall be
deemed to be the initial bona fide offering thereof.

Apple Common Stock, subject in all cases to any applicable escheat laws. No
interest will be payable with respect to the payment of such dividends or other
distributions or cash for and in lieu of fractional shares on surrender of
outstanding certificates.

               Section 2.06 FRACTIONAL SHARES. Notwithstanding any other
provision herein, no fractional shares of Apple Common Stock will be issued, and

Stock but for this Section 2.06 will have the cash portion of the Merger

1100 Louisiana, Houston, Texas at 10:00 a.m., Houston time, or at such later
time on the IPO Pricing Date as Apple shall specify by written notice to Robert

transactions contemplated by this Agreement to be closed or completed on or
before the IPO Closing Date, including the surrender of the Company Common Stock
in exchange for the Merger Consideration (including a certified check or checks

pursuant to Section 12.01(b)(i).

               (b) CERTAIN CONDITIONS TO THE OBLIGATIONS OF THE COMPANY AND THE
STOCKHOLDERS. The obligations of the Company and the Stockholders with respect

                     COVENANTS FOLLOWING THE EFFECTIVE TIME

               Section 8.01 OF EACH PARTY OTHER THAN THE COMPANY. From and after
the Effective Time, subject to the waiver provisions of Section 11.05, each
party hereto (other than the Company) will comply with each covenant for which

________________.

                                   ARTICLE X.

                           LIMITATIONS ON COMPETITION

               Section 10.01 PROHIBITED ACTIVITIES. Each Stockholder agrees,
severally and not jointly with any other Person, that he will not, during the
period beginning on the date hereof and ending on the fifth anniversary of the
date hereof, directly or indirectly, for any reason, for his own account or on
behalf of or together with any other Person:

               (a) engage as an officer, director or in any other managerial
        capacity or as an owner, co-owner or other investor of or in, whether as
        an employee, independent contractor, consultant or advisor, or as a
        sales representative or distributor of any kind, in any business selling
        any products or providing any services in competition with the Company,
        any Company Subsidiary or Apple or any Subsidiary of Apple (Apple and
        its Subsidiaries collectively being "Apple" for purposes of this Article
        X) within a radius of ____ miles of each location in which any of the
        Company or the Company Subsidiaries was engaged in business on the date
        hereof or immediately prior to the Effective Time (those locations
        collectively being the "Territory");

               (b) call on any natural person who is at that time employed by
        the Company, any Company Subsidiary or Apple with the purpose or intent
        of attracting that person from the employ of the Company, any Company
        Subsidiary or Apple, provided that the Stockholder may call on and hire
        any of his Immediate Family Members;

               (c) call on any Person that at that time is, or at any time
        within one year prior to that time was, a customer of the Company, any
        Company Subsidiary or Apple within the Territory, (i) for the purpose of
        soliciting or selling any product or service in

                                       11
<PAGE>
        competition with the Company, any Company Subsidiary or Apple within the
        Territory and (ii) with the knowledge of that customer relationship; or

               (d) call on any Apple Acquisition Candidate, with the knowledge
        of that Person's status as an Apple Acquisition Candidate, for the
        purpose of acquiring that Person or arranging the acquisition of that
        Person by any Person other than Apple.

Notwithstanding the foregoing, any Stockholder may own and hold as a passive
investment up to 1% of the outstanding Capital Stock of a competing Entity if
that class of Capital Stock is listed on the New York Stock Exchange or included
in the Nasdaq National Market. For purposes hereof and the respective Tax
reporting positions of the parties hereto, each party hereto agrees that the
percentage of the cash portion of the Merger Consideration to be received by
each Stockholder pursuant to Section 2.04 which equals 1% of that Stockholder's
Pro Rata Share of the Transaction Value will represent, and be received as,
consideration for that Stockholder's agreement to observe the covenants in this
Section 10.01.

               Section 10.02 DAMAGES. Because of the difficulty of measuring
economic losses to Apple as a result of any breach by a Stockholder of his
covenants in Section 10.01, and because of the immediate and irreparable damage
that could be caused to Apple for which it would have no other adequate remedy,
each Stockholder agrees that Apple may enforce the provisions of Section 10.01
by injunctions and restraining orders against that Stockholder if he breaches
any of those provisions.

               Section 10.03 REASONABLE RESTRAINT. The parties hereto each agree
that Sections 10.01 and 10.02 impose a reasonable restraint on the Stockholders
in light of the activities and business of Apple on the date hereof, the current
business plans of Apple and the investment by each Stockholder in Apple as a
result of the Merger.

               Section 10.04 SEVERABILITY; REFORMATION. The covenants in this
Article X are severable and separate, and the unenforceability of any specific
covenant in this Article X is not intended by any party hereto to, and shall
not, affect the provisions of any other covenant in this Article X. If any court
of competent jurisdiction shall determine that the scope, time or territorial
restrictions set forth in Section 10.01 are unreasonable as applied to any
Stockholder, the parties hereto, including that Stockholder, acknowledge their
mutual intention and agreement that those restrictions be enforced to the
fullest extent the court deems reasonable, and thereby shall be reformed to that
extent as applied to that Stockholder and any other Stockholder similarly
situated.

               Section 10.05 INDEPENDENT COVENANT. All the covenants in this
Article X are intended by each party hereto to, and shall, be construed as an
agreement independent of any other provision in this Agreement, and the
existence of any claim or cause of action of any Stockholder against Apple,
whether predicated on this Agreement or otherwise, shall not constitute a
defense to the enforcement by Apple of any covenant in this Article X. It is
specifically agreed that the period specified in Section 10.01 shall be computed
in the case of each Stockholder by excluding from that computation any time
during which that Stockholder

                                       12
<PAGE>
is in violation of any provision of Section 10.01. The covenants contained in
this Article X shall not be affected by any breach of any other provision hereof
by any party hereto.

               Section 10.06 MATERIALITY. The Company and each Stockholder,
severally and not jointly with any other Person, hereby agree that this Article
X is a material and substantial part of the transactions contemplated hereby.

                                   ARTICLE XI.

                               GENERAL PROVISIONS

               Section 11.01 TREATMENT OF CONFIDENTIAL INFORMATION. Each party
hereto will comply with each covenant for which provision is made in Section
11.15 of the Uniform Provisions (the text of which Section hereby is
incorporated herein by this reference) to be performed or observed by that
party.

               Section 11.02 RESTRICTIONS ON TRANSFER OF APPLE COMMON STOCK. (a)
During the two-year period ending on the second anniversary of the IPO Closing
Date (the "Restricted Period") (or if the two-year "holding" period for
restricted securities under Rule 144 under the Securities Act is reduced by the
SEC, the Restricted Period will be correspondingly reduced), no Stockholder
voluntarily will, except pursuant to and in accordance with the applicable
provisions of the Registration Rights Agreement: (i) sell, assign, exchange,
transfer, encumber, pledge, distribute, appoint or otherwise dispose of (A) any
shares of Apple Common Stock received by any Stockholder in the Merger or (B)
any interest in (including any option to buy or sell) any of those shares of
Apple Common Stock, in whole or in part, and Apple will have no obligation to,
and shall not, treat any such attempted transfer as effective for any purpose;
or (ii) engage in any transaction, whether or not with respect to any shares of
Apple Common Stock or any interest therein, the intent or effect of which is to
reduce the risk of owning the shares of Apple Common Stock acquired pursuant to
Section 2.04 (including, for example engaging in put, call, short-sale, straddle
or similar market transactions); provided, however, that this Section 11.02
shall not restrict any transfer of Apple Common Stock acquired by a Stockholder
pursuant to Section 2.04 to any of that Stockholder's Related Persons who agree
in writing to be bound by the provisions of Section 11.01 and this Section
11.02. The certificates evidencing the Apple Common Stock delivered to each
Stockholder pursuant to Section 2.05 will bear a legend substantially in the
form set forth below and containing such other information as Apple may deem
necessary or appropriate:

        EXCEPT PURSUANT TO THE TERMS OF THE AGREEMENT AND PLAN OF REORGANIZATION
        AMONG THE ISSUER, THE HOLDER OF THIS CERTIFICATE AND THE OTHER PARTIES
        THERETO, THE SHARES REPRESENTED BY THIS CERTIFICATE MAY NOT BE

        DISTRIBUTED, APPOINTED OR OTHERWISE DISPOSED OF, AND THE ISSUER SHALL
        NOT BE REQUIRED TO GIVE EFFECT TO ANY ATTEMPTED VOLUNTARY SALE,
        ASSIGNMENT, EXCHANGE, TRANSFER, ENCUMBRANCE, PLEDGE, DISTRIBUTION,
        APPOINTMENT

                                       13
<PAGE>
        OR OTHER DISPOSITION OF ANY OF THOSE SHARES, DURING THE TWO-YEAR PERIOD
        ENDING ON __________ [DATE THAT IS THE SECOND ANNIVERSARY OF THE IPO
        CLOSING DATE] (THE "RESTRICTED PERIOD") (OR IF THE TWO YEAR "HOLDING"
        PERIOD FOR RESTRICTED SECURITIES UNDER RULE 144 UNDER THE SECURITIES ACT
        OF 1933 IS REDUCED BY THE SECURITIES AND EXCHANGE COMMISSION, THE
        RESTRICTED PERIOD WILL BE CORRESPONDINGLY REDUCED). ON THE WRITTEN
        REQUEST OF THE HOLDER OF THIS CERTIFICATE, THE ISSUER AGREES TO REMOVE
        THIS RESTRICTIVE LEGEND (AND ANY STOP ORDER PLACED WITH THE TRANSFER
        AGENT) AFTER THE DATE SPECIFIED ABOVE.

               (b) Each Stockholder, severally and not jointly with any other
Person, (i) acknowledges that the shares of Apple Common Stock to be delivered
to that Stockholder pursuant to Section 2.04 have not been and, except pursuant
to the Registration Rights Agreement, if applicable, will not be registered
under the Securities Act and therefore may not be resold by that Stockholder
without compliance with the Securities Act and (ii) covenants that none of the
shares of Apple Common Stock issued to that Stockholder pursuant to Section 2.04
will be offered, sold, assigned, pledged, hypothecated, transferred or otherwise
disposed of except after full compliance with all the applicable provisions of
the Securities Act and the rules and regulations of the SEC and applicable state
securities laws and regulations. All certificates evidencing shares of Apple
Common Stock issued pursuant to Section 2.04 will bear the following legend in
addition to the legend prescribed by Section 11.02(a):

        THE SHARES REPRESENTED HEREBY HAVE NOT BEEN REGISTERED UNDER THE
        SECURITIES ACT OF 1933 AND MAY ONLY BE SOLD OR OTHERWISE TRANSFERRED IF
        THE HOLDER HEREOF COMPLIES WITH THAT LAW AND OTHER APPLICABLE SECURITIES
        LAWS.

In addition, certificates evidencing shares of Apple Common Stock issued
pursuant to Section 2.04 to each Stockholder will bear any legend required by
the securities or blue sky laws of the state in which that Stockholder resides.

               Section 11.03 BROKERS AND AGENTS. Except as disclosed in the
Private Placement Memorandum or in Section 11.03 of the Disclosure Statement,
the Stockholders jointly and severally represent and warrant to Apple that the
Company has not directly or indirectly employed or become obligated to pay any
broker or similar agent in connection with the transactions contemplated hereby,
and agree, without regard to the Threshold Amount limitations set forth in
Article IX, to indemnify Apple against all Damage Claims arising out of claims
for any and all fees and commissions of brokers or similar agents employed or
promised payment by the Company.

               Section 11.04 ASSIGNMENT; NO THIRD PARTY BENEFICIARIES. This
Agreement and the rights of the parties hereunder may not be assigned (except by
operation of law) and shall be binding on and inure to the benefit of the
parties hereto, the successors of Apple, and the heirs and legal representatives
of the Stockholders (and, in the case of any trust, the successor

                                       14
<PAGE>
trustees of that trust). Neither this Agreement nor any other Transaction
Document is intended, or shall be construed, deemed or interpreted, to confer on
any Person not a party hereto or thereto any rights or remedies hereunder or
thereunder, except as provided in Section 6.05(b) or 11.14, in Article IX or as
otherwise provided expressly herein or therein.

               Section 11.05 ENTIRE AGREEMENT; AMENDMENT; WAIVERS. This
Agreement and the documents delivered pursuant hereto constitute the entire
agreement and understanding among the Stockholders, the Company and Apple and
supersede all prior agreements and understandings, both written and oral,
relating to the subject matter of this Agreement. This Agreement may be amended,
modified or supplemented, and any right hereunder may be waived, if, but only
if, that amendment, modification, supplement or waiver is in writing and signed
by the Required Stockholders, the Company and Apple; provided, however, that no
such amendment, modification, supplement or waiver will be effective unless it
is signed by each Stockholder affected thereby to the extent that it (a) changes
the several nature of that Stockholder's representations and warranties (to the
extent they are not already joint and several as provided in Sections 4.01 and
11.03), (b) reduces the amount, or changes the components, of the Merger
Consideration that Stockholder is entitled to receive pursuant to Section 2.04,
as adjusted pursuant to Section 2.05(f), (c) waives the consummation of the IPO
as a condition to consummation of the Merger or (d) amends or waives this
sentence. The waiver of any of the terms and conditions hereof shall not be
construed or interpreted as, or deemed to be, a waiver of any other term or
condition hereof.

               Section 11.06 COUNTERPARTS. This Agreement may be executed in
multiple counterparts, each of which will be an original, but all of which
together will constitute one and the same instrument.

               Section 11.07 EXPENSES. Whether or not the transactions
contemplated hereby are consummated, (a) Apple will pay the fees, expenses and
disbursements of Apple and their Representatives which are incurred in
connection with the subject matter of this Agreement and any amendments thereto,
including all costs and expenses incurred in the performance of and compliance
with all conditions to be performed by Apple under this Agreement, including the
costs of preparing the Registration Statement, and (b) the Stockholders will pay
from personal funds, and not from funds of the Company or any Company
Subsidiary, all sales, use, transfer and other similar taxes and fees
(collectively, "Transfer Taxes") incurred in connection with the transactions
contemplated hereby, and the fees, expenses and disbursements of Counsel for the
Company and the Stockholders incurred in connection with the subject matter of
this Agreement and the Registration Statement on or before the IPO Closing Date;
provided, however, if the Company or the Required Stockholders terminate this
Agreement otherwise than as permitted by Article XII, the Company will, no later
than 10 Houston, Texas business days after Apple makes a written request
therefor, reimburse Apple in the amount equal to the aggregate fees, costs and
other expenses invoiced to Apple by Arthur Andersen LLP in connection with its
audit of the Company's financial statements at December 31, 1996 and for the
12-month period then ended; provided further, however, that a Stockholder's
estate shall not be required to reimburse Apple for such fees, costs and
expenses in the event such termination follows the death of the Stockholder. The
Stockholders will file all necessary documentation and Returns with respect to
all Transfer Taxes. In addition, each Stockholder acknowledges that he, and not
the Company

                                       15
<PAGE>
or Apple or the Surviving Corporation, will pay all Taxes due upon receipt of
the consideration payable to that Stockholder pursuant to Article II.

OF THE STATE OF TEXAS WITHOUT REGARD TO THE CONFLICTS OF LAW PROVISIONS THEREOF.

               Section 11.10 EXERCISE OF RIGHTS AND REMEDIES. Except as
otherwise provided herein, no delay or omission in the exercise of any right,
power or remedy accruing to any party hereto as a result of any breach or
default hereunder by any other party hereto shall impair any such right, power
or remedy, nor shall it be construed, deemed or interpreted as a waiver of or
acquiescence in any such breach or default, or of any similar breach or default
occurring later; nor shall any waiver of any single breach or default be
construed, deemed or interpreted as a waiver of any other breach or default
hereunder occurring before or after that waiver.

               Section 11.11 TIME. Time is of the essence in the performance of 
this Agreement in all respects.

               Section 11.12 REFORMATION AND SEVERABILITY. If any provision of
this Agreement is invalid, illegal or unenforceable, that provision shall, to
the extent possible, be modified in such manner as to be valid, legal and
enforceable but so as to most nearly retain the intent of the parties hereto as
expressed herein, and if such a modification is not possible, that provision
shall be severed from this Agreement, and in either case the validity, legality
and enforceability of the remaining provisions of this Agreement shall not in
any way be affected or impaired thereby.

               Section 11.13 REMEDIES CUMULATIVE. No right, remedy or election
given by any term of this Agreement shall be deemed exclusive, but each shall be
cumulative with all other rights, remedies and elections available at law or in
equity.

               Section 11.14 RESPECTING THE IPO. Each of the Company and the
Stockholders acknowledges and agrees that: (a) no firm commitment, binding
agreement or promise or other assurance of any kind, whether express or implied,
oral or written, exists at the date hereof that the Registration Statement will
become effective or that the IPO will occur at a particular price or within a
particular range of prices or occur at all; (b) neither Apple or any of its
Representatives nor any prospective underwriters in the IPO will have any
liability to the Company, the Stockholders or any of their respective Affiliates
or associates for any failure of (i) the Registration Statement to become
effective (provided, however, that Apple will use its reasonable best efforts to
cause the Registration Statement to become effective prior to December 31, 1997)
or (ii) the IPO to occur at a particular price or within a particular range of
prices or to occur at all; and (c) the decision of Stockholders to enter into
this Agreement, or to vote in favor of or consent to the Merger, has been or
will be made independent of, and without reliance on, any statements, opinions
or other communications of, or due diligence investigations that have been or
will be made or performed by, any prospective underwriter relative to Apple or
the IPO. The Underwriter shall have no obligation to any of the Company and the
Stockholders or with respect to any disclosure contained in the Registration
Statement.

               Section 12.01 TERMINATION OF THIS AGREEMENT. (a) This Agreement
may be terminated at any time prior to the Closing solely:

                    (i)      by the mutual written consent of Apple and the
        Company;

                   (ii) by the Stockholders or the Company, on the one hand, or
        by Apple, on the other hand, if the transactions contemplated by this
        Agreement to take place at the Closing shall not have been consummated
        by December 31, 1997, unless the failure of such transactions to be
        consummated results from the willful failure of the party (or in the
        case of the Stockholders and the Company, any of them) seeking to
        terminate this Agreement to perform or adhere to any agreement required
        hereby to be performed or adhered to by it prior to or at the Closing or
        thereafter on the IPO Closing Date;

                  (iii) by the Stockholders or the Company, on the one hand, or
        by Apple, on the other hand, if a material breach or default shall be
        made by the other party (or in the case of the Stockholders and the
        Company, any of them) in the observance or in the due and timely
        performance of any of the covenants, agreements or conditions contained
        herein; or

                   (iv)      by Apple if it is entitled to do so as provided in
        Section 6.08;

               (b)    This Agreement may be terminated after the Closing solely:

                    (i)      by Apple or the Company if the Underwriting
        Agreement is terminated pursuant to its terms after the Closing and 
        prior to the consummation of the IPO; or

                   (ii) automatically and without action on the part of any
        party hereto if the IPO is not consummated within 15 New York City
        business days after the date of the Closing.

               (c) If this Agreement is terminated pursuant to this Section
12.01, the Merger will be deemed for all purposes to have been abandoned and of
no force or effect. If this Agreement is terminated pursuant to this Section
12.01 after the Certificate of Merger has been filed with the Secretary of State
of the State of _______________, but before the IPO has been consummated, Apple
will take all actions that Counsel for the Company and the Stockholders advises
Apple are required by the applicable laws of the State of _______________ in
order to rescind the Merger.

               Section 12.02 LIABILITIES IN EVENT OF TERMINATION. If this
Agreement is terminated pursuant to Section 12.01, there shall be no liability
or obligation on the part of any party hereto except (a) as provided in Section
11.07 and (b) to the extent that such liability is based on the breach by that
party of any of its representations, warranties or covenants set forth in this
Agreement.

                         liability or is (or will be) subject

                         account of or in respect of any direct
                         or indirect failure by the Company,
                         any Company Subsidiary or any

                         Time directly or indirectly against
                         the Company, any Company Subsidiary,
                         any Stockholder, the Surviving
                         Corporation or Apple with respect to
                         any of those group health plans;

                 (vi)    the Financial Statements as of the
                         Current Balance Sheet Date reflect the
                         approximate total unfunded (or
                         uninsured) pension, medical and other
                         benefit liability for all Plans
                         determined in accordance with
                         accounting principles and actuarial
                         assumptions consistently applied in
                         the ongoing administration of the
                         Plans; and

                (vii)    neither the Company nor any Company Subsidiary has
                         incurred liability under Section 4062 of ERISA.

           (d) MULTIEMPLOYER PLANS. Except as set forth in Section 4.27(d) of
the Disclosure Statement, neither the Company nor any Company Subsidiary, and no
ERISA Affiliate of any of them, is, or at any time during the six-year period
ended on the date hereof was, obligated to contribute to a Multiemployer Plan.
Neither the Company nor any Company Subsidiary, and no ERISA Affiliate of any of
them, has made a complete or partial withdrawal from a Multiemployer Plan so as
to incur withdrawal liability as defined in Section 4201 of ERISA.

           (e) CLAIMS AND LITIGATION. Except as accurately set forth in Section
4.27(e) of the Disclosure Statement, no Litigation or claims (other than routine
claims for benefits) are pending or, to the knowledge of the Company, threatened
against, or with respect to, any of the Plans or with respect to any fiduciary,
administrator or sponsor thereof (in their capacities as such), or any
party-in-interest thereof.

           (f) EXCISE TAXES, DAMAGES AND PENALTIES. No act, omission or

Section 409 of ERISA, (ii) a civil penalty assessed pursuant to subsection (c),
(i) or (l) of Section 502 of ERISA or (iii) any excise tax under applicable
provisions of the Code with respect to any Plan.

             (g) VEBA WELFARE TRUST. Any trust funding a Plan, which is intended
to be exempt from federal income taxation pursuant to Section 501(c)(9) of the
Code, satisfies the requirements of that section and has received a favorable
exemption letter from the IRS

                                       30
<PAGE>
regarding that exempt status and has not, since receipt of the most recent
favorable exemption letter, been amended or operated in a way that would
adversely affect that exempt status. The value of assets of each trust described
in this Section 4.27(g) equals or exceeds the value of benefit liabilities of
such trust (or related Plan) determined in accordance with actuarial assumptions
consistently applied in the ongoing administration of such trust (or related
plan).

Company Subsidiaries have been paid, each Tax payable by the Company or a
Company Subsidiary by assessment has been timely paid in the amount assessed and
adequate reserves have been established on the consolidated books of the Company
and the Company Subsidiaries for all Taxes for which any of the Company and the
Company Subsidiaries is liable, but the payment of which is not yet due. Neither
the Company nor any Company Subsidiary is, or ever has been, liable for any Tax
payable by reason of the income or property of a Person other than the Company
or a Company Subsidiary. Each of the Company and the Company Subsidiaries has
timely filed true, correct and complete declarations of estimated Tax in each
jurisdiction in which any such declaration is required to be filed by it. No
Liens for Taxes exist upon the assets of the Company or any Company Subsidiary
except Liens for Taxes which are not yet due. Neither the Company nor any
Company Subsidiary is, or ever has been, subject to Tax in any jurisdiction
outside of the United States. No Litigation with respect to any Tax for which
the Company or any Company Subsidiary is asserted to be liable is pending or, to
the knowledge of the Company or any Stockholder, threatened and no basis which
the Company or any Stockholder believes to be valid exists on which any claim
for any such Tax can be asserted against the Company or any Company Subsidiary.
There are no requests for rulings or determinations in respect of any Taxes
pending between the Company or any Company Subsidiary and any Taxing Authority.
No extension of any period during which any Tax may be assessed or collected and
for which the Company or any Company Subsidiary is or may be liable has been
granted to any Taxing Authority. Neither the Company nor any Company Subsidiary
is or has been a party to any tax allocation or sharing agreement. All amounts
required to be withheld by any of the Company and the Company Subsidiaries and
paid to governmental agencies for income, social security, unemployment
insurance, sales, excise, use and other Taxes have been collected or withheld
and paid to the proper Taxing Authority. The Company and each Company Subsidiary
have made all deposits required by law to be made with respect to employees'
withholding and other employment taxes.

           (c) Neither the Company, any Company Subsidiary nor any Stockholder
is a "foreign person," as that term is referred to in Section 1445(f)(3) of the
Code.

           (d) Neither the Company, nor any Company Subsidiary, has filed a
consent pursuant to Section 341(f) of the Code or any comparable provision of
any other Tax statute, nor has agreed to have Section 341(f)(2) of the Code or
any comparable provision of any other

                                       31
<PAGE>
Tax statute apply to any disposition of an asset. Neither the Company, nor any
Company Subsidiary, has made, is obligated to make or is a party to any
agreement that could require it to make any payment that is not, or would not
be, deductible under Section 280G of the Code. No asset of the Company or of any
Company Subsidiary is subject to any provision of applicable law which
eliminates or reduces the allowance for depreciation or amortization in respect
of that asset below the allowance generally available to an asset of its type.
No accounting method changes of the Company or of any Company Subsidiary exist
or are proposed or threatened which could give rise to an adjustment under

Stockholder or the Company to comply with or satisfy any covenant, condition or
agreement to be complied with or satisfied by that Person hereunder, provided

the Disclosure Statement, as would be necessary, in the light of the
circumstances, conditions, events and states of facts then known to the Company
or any Stockholder, to make each of those representations and warranties true
and correct as of the Closing and on the IPO Closing Date. For purposes only of
determining whether the conditions to the obligations of Apple which are
specified in Sections 7.04(a)(ii)(A) and 7.04(b)(ii) have been satisfied, and
not for any purpose under Article IX, the Disclosure Statement as of the Closing
and on the IPO Closing Date shall be deemed to be the Disclosure Statement as of
the date hereof as amended or supplemented by the Supplemental Information

Surviving Corporation, as the case may be, Apple will be entitled either (i) to
terminate this Agreement pursuant to Section 12.01(d) or (ii) to treat as Apple

prejudice the right of any Stockholder under Article IX to contest Damage Claims
made by Apple in respect of those Apple Indemnified Losses) all Damages to the
Company or the Surviving Corporation which are attributable to the
circumstances, conditions, events and states of facts first disclosed herein
after the date hereof in the Supplemental Information. Apple will provide the

time during the period in which a prospectus relating to the IPO is required to
be delivered under the Securities Act, any information contained in the then
current Registration Statement prospectus concerning the Company or the
Stockholders becomes incorrect or incomplete in any material respect and (b)
provide Apple with the information needed to correct or complete that
information.

fiscal year ended with that quarter, in each case (i) setting forth in
comparative form the figures for the corresponding portion of the Company's

the Company will, or will cause the applicable Company Subsidiary to, if
permitted by all applicable Governmental Requirements to do so, terminate each
Plan identified in Section 4.26(c) or (d) of the Disclosure Statement as a "Plan
To Be Terminated" (or in the case of Company ERISA Benefit Plans, or Company
ERISA Pension Plans, remove such Plans from the Company and transfer sponsorship
of such Plans to the Orthodontic Entity) prior to the Effective Time.

           Section 6.12 DISPOSITION OF UNWANTED ASSETS. At or prior to the
Closing, the Company will make all arrangements and take all such actions as are
necessary and satisfactory to Apple to convey to the Orthodontic Entity, prior
to the Effective Time, each asset of it or of one or more of the Company
Subsidiaries that by law cannot be acquired by Apple because it relates to the
practice of dentistry, which assets are listed in Section 6.12 of the Disclosure
Statement, and each other asset listed in Section 6.12 of the Disclosure
Statement.

           Section 6.13 HSR ACT MATTERS. If Apple shall determine that filings
pursuant to and under the HSR Act are necessary or appropriate in connection
with the effectuation of the Merger or the consummation of the acquisitions
contemplated by the Other Agreements, and advises the Company in writing of that
determination, the Company promptly will compile and file under the HSR Act such
information respecting it as the HSR Act requires of an Entity to be acquired,
and the expiration or termination of the applicable waiting period and any
extension thereof under the HSR Act shall be deemed a condition precedent set
forth in Section 7.02(b).

           Section 6.14 RETIREMENT OF DEBT. The Company shall repay all of its
outstanding Indebtedness on or prior to the IPO Closing Date.

prospectus and the Stockholder timely provided, in writing, corrected or the
necessary additional information to Apple and its counsel for inclusion in the
Final Prospectus. For purposes of subclause (iv) above, the portion of any Tax
for a taxable period that begins before and ends after the IPO Closing Date that

prospectus relating to the IPO, the Registration Statement or any prospectus
forming a part thereof, or any amendment thereof or supplement thereto, or (B)
any omission or alleged omission to state therein a material fact relating
solely to that Stockholder required to be stated therein or necessary to make
the statements therein not misleading, and not provided to Apple or its counsel
by that Stockholder; provided, however, that no Stockholder shall be obligated
to indemnify any Apple Indemnified Party against any Apple Indemnified Loss to
the extent that such untrue statement (or alleged untrue statement) was made in,
or such omission (or alleged omission) occurred in, any preliminary prospectus
and the Stockholder timely provided, in writing, corrected or the necessary
additional information to Apple and its counsel for inclusion in the Final
Prospectus.

resulting delay is materially prejudicial to the defense of that claim. Within
15 days after receipt of any Claim Notice (the "Election Period"), the
Indemnifying Party shall notify the Indemnified Party (i) whether the
Indemnifying Party disputes its potential liability to the Indemnified Party
under this Article IX with respect to that Third Party Claim and (ii) if the
Indemnifying Party does not dispute its potential liability to the Indemnified
Party with respect to that Third Party Claim, whether the Indemnifying Party
desires, at the sole cost and expense of the Indemnifying Party, to defend the
Indemnified Party against that Third Party Claim.

           (c) If the Indemnifying Party does not dispute its potential
liability to the Indemnified Party and notifies the Indemnified Party within the
Election Period that the Indemnifying Party elects to assume the defense of the
Third Party Claim, then the Indemnifying Party shall have the right to defend,
at its sole cost and expense, that Third Party Claim by all appropriate
proceedings, which proceedings shall be prosecuted diligently by the
Indemnifying Party to a final conclusion or settled at the discretion of the
Indemnifying Party in accordance with this Section 9.05(c) and the Indemnified
Party will furnish the Indemnifying Party with all information in its possession
with respect to that Third Party Claim and otherwise cooperate with the
Indemnifying Party in the defense of that Third Party Claim; provided, however,
that the Indemnifying Party shall not enter into any settlement with respect to
any Third Party Claim that purports to limit the activities of, or otherwise
restrict in any way, any Indemnified Party or any Affiliate of any Indemnified
Party without the prior consent of that Indemnified Party (which consent may be
withheld in the sole discretion of that Indemnified Party). The Indemnified
Party is hereby authorized, at the sole cost and expense of the Indemnifying
Party, to file, during the Election Period, any motion, answer or other
pleadings that the Indemnified Party shall deem necessary or appropriate to
protect its interests or those of the Indemnifying Party.

The Indemnified Party may participate in, but not control, any defense or
settlement of any Third Party Claim controlled by the Indemnifying Party
pursuant to this Section 9.05(c) and will bear its own costs and expenses with
respect to that participation; provided, however, that if the named parties to
any such action (including any impleaded parties) include both the Indemnifying
Party and the Indemnified Party, and the Indemnified Party has been advised by
counsel that there may be one or more legal defenses available to it which are
different from or additional to those available to the Indemnifying Party, then
the Indemnified Party may employ separate counsel at the expense of the
Indemnifying Party, and, on its written notification of that employment, the
Indemnifying Party shall not have the right to assume or continue the defense of
such action on behalf of the Indemnified Party.

           (d) If the Indemnifying Party (i) within the Election Period (A)
disputes its potential liability to the Indemnified Party under this Article IX,
(B) elects not to defend the Indemnified Party pursuant to Section 9.05(c) or
(C) fails to notify the Indemnified Party that the Indemnifying Party elects to
defend the Indemnified Party pursuant to Section 9.05(c) or (ii) elects to
defend the Indemnified Party pursuant to Section 9.05(c) but fails diligently
and promptly to prosecute or settle the Third Party Claim, then the Indemnified
Party shall have the right to defend, at the sole cost and expense of the
Indemnifying Party (if the Indemnified Party is entitled to indemnification
hereunder), the Third Party Claim by all appropriate proceedings, which
proceedings shall be promptly and vigorously prosecuted by the Indemnified Party
to a final conclusion or settled. The Indemnified Party shall have full control
of such defense and proceedings. Notwithstanding the foregoing, if the
Indemnifying Party has delivered a written notice to the Indemnified Party to
the effect that the Indemnifying Party disputes its potential liability to the
Indemnified Party under this Article IX and if such dispute is resolved in favor
of the Indemnifying Party, the Indemnifying Party shall not be required to bear
the costs and expenses of the Indemnified Party's defense pursuant to this
Section 9.05 or of the Indemnifying Party's participation therein at the
Indemnified Party's request, and the Indemnified Party shall reimburse the
Indemnifying Party in full for all reasonable costs and expenses of such
litigation. The Indemnifying Party may participate in, but not control, any
defense or settlement controlled by the Indemnified Party pursuant to this
Section 9.05(d), and the Indemnifying Party shall bear its own costs and
expenses with respect to such participation.

           (e) In the event any Indemnified Party should have a claim against
any Indemnifying Party hereunder that does not involve a Third Party Claim, the
Indemnified Party shall transmit to the Indemnifying Party a written notice (the
"Indemnity Notice") describing in reasonable detail the nature of the claim, an
estimate of the amount of Damages attributable to that claim to the extent
feasible (which estimate shall not be conclusive of the final amount of such
claim) and the basis of the Indemnified Party's request for indemnification
under this Agreement. If the Indemnifying Party does not notify the Indemnified
Party within 15 days from its receipt of the Indemnity Notice that the
Indemnifying Party disputes such claim, the claim specified by the Indemnified
Party in the Indemnity Notice shall be deemed a liability of the Indemnifying
Party hereunder. If the Indemnifying Party has timely disputed such claim, as
provided above, such dispute shall be resolved by proceedings in an appropriate
court of competent jurisdiction if the parties do not reach a settlement of such
dispute within 30 days after notice of a dispute is given.

                                       52

           (f) Payments of all amounts owing by an Indemnifying Party pursuant
to this Article IX relating to a Third Party Claim shall be made within 30 days
after the latest of (i) the settlement of that Third Party Claim, (ii) the
expiration of the period for appeal of a final adjudication of that Third Party
Claim or (iii) the expiration of the period for appeal of a final adjudication
of the Indemnifying Party's liability to the Indemnified Party under this
Agreement. Payments of all amounts owing by an Indemnifying Party pursuant to
Section 9.05(e) shall be made within 30 days after the later of (i) the
expiration of the 30-day Indemnity Notice period or (ii) the expiration of the
period for appeal of a final adjudication of the Indemnifying Party's liability
to the Indemnified Party under this Agreement.

           Section 9.06 REMEDIES NOT EXCLUSIVE. The remedies provided in this
Agreement shall not be exclusive of any other rights or remedies available to
one party against the other, either at law or in equity.

           Section 9.07 LIMITATIONS ON INDEMNIFICATION. (a) Notwithstanding the
provisions of Section 9.03(a), neither the Company nor any of the Stockholders
shall be required to indemnify or hold harmless any of the Apple Indemnified
Parties on account of any Apple Indemnified Loss under Section 9.03(a) unless
the liability of the Company and the Stockholders in respect of that Apple
Indemnified Loss, when aggregated with the liability of the Company and the
Stockholders in respect of all Apple Indemnified Losses under Section 9.03(a),
exceeds, and only to the extent the aggregate amount of all those Apple
Indemnified Losses does exceed, the Threshold Amount. In no event shall (i) the
aggregate joint and several liability of the Company and the Stockholders under
this Agreement, including Section 9.03(a), exceed the Transaction Value or (ii)
the aggregate liability of each Stockholder under this Agreement, including
Sections 9.03(a) and 9.03(b), exceed that Stockholder's Pro Rata Share of the
Transaction Value. For purposes of determining the amount of Apple Indemnified
Losses, no effect will be given to any resulting Tax benefit to any Apple
Indemnified Party.

           (b) Notwithstanding the provisions of Section 9.04, Apple shall not
be required to indemnify or hold harmless any of the Stockholder Indemnified
Parties on account of any Stockholder Indemnified Loss unless the liability of
Apple in respect of that Stockholder Indemnified Loss, when aggregated with the
liability of Apple in respect of all Stockholder Indemnified Losses, exceeds,
and only to the extent the aggregate amount of all those Stockholder Indemnified
Losses does exceed, the Threshold Amount. In no event shall Apple be liable
under this Agreement, including Section 9.04, for any amount in excess of the
Transaction Value. For purposes of determining the amount of Stockholder
Indemnified Losses, no effect will be given to any resulting Tax benefit to any
Stockholder Indemnified Party.

                               GENERAL PROVISIONS

           Section 11.15 TREATMENT OF CONFIDENTIAL INFORMATION. (a) Each of the
Company and the Stockholders, severally and not jointly with any other Person,
acknowledges that it has or may have had in the past, currently has and in the
future may have access to Confidential

                                       53
<PAGE>
Information of the Company and the Company Subsidiaries, the Other Founding
Companies and their Subsidiaries and Apple and its Subsidiaries. Each of the
Company and the Stockholders, severally and not jointly with any other Person,
agrees that it will keep confidential all such Confidential Information
furnished to it and, except with the specific prior written consent of Apple
will not disclose such Confidential Information to any Person except (a)
Representatives of Apple, (b) its own Representatives, provided that these
Representatives (other than counsel) agree to the confidentiality provisions of
this Section 11.15; and provided, further, that Confidential Information shall
not include (i) such information which becomes known to the public generally
through no fault of any Stockholder, (ii) information required to be disclosed
by law or the order of any governmental authority under color of law, provided,
that prior to disclosing any information pursuant to this clause (ii), each
Stockholder shall, if possible, give prior written notice thereof to Apple and
provide Apple with the opportunity to contest such disclosure, or (iii) the
disclosing party reasonably believes that such disclosure is required in
connection with the defense of a lawsuit against the disclosing party. In the
event of a breach or threatened breach by any Stockholder of the provisions of
this Section 11.15 with respect to any Confidential Information, Apple shall be
entitled to an injunction restraining such Stockholder from disclosing, in whole
or in part, that Confidential Information. Nothing herein shall be construed as
prohibiting Apple from pursuing any other available remedy for such breach or
threatened breach, including the recovery of damages.

           (b) Because of the difficulty of measuring economic losses as a
result of the breach of the foregoing covenants in Section 11.15(a), and because
of the immediate and irreparable damage that would be caused to Apple for which
it would have no other adequate remedy, each of the Company and the Stockholders
agrees that Apple may enforce the provisions of Section 11.15(a) by injunctions
and restraining orders against each of them who breaches any of those
provisions.

           (c) The obligations of Apple set forth in Section 6.02(d) are
incorporated in this Section 11.15 by this reference.

           (d) The obligations of the parties under this Section 11.15 shall
survive the termination of this Agreement.

                  include any Exempt Person; provided, however, that a Person
                  shall not be or become an Acquiring Person if such Person,

                  case, such Person, together with all Affiliates and Associates
                  of such Person, is not then the Beneficial Owner of

                  personal injury he has incurred (including illness or injury
                  resulting from any substance abuse), by a Qualified Physician,
                  to be unable to perform, at the time of that determination
                  and, in all reasonable medical likelihood, indefinitely
                  thereafter, the normal duties then most recently assigned,
                  under and in accordance with the terms hereof, to the Employee
                  during the term hereof; provided that, the determination
                  whether the Employee has incurred a Disability shall be made
                  by the Company by it causing the selection of three (3)
                  Qualified Physicians, the majority determination of which
                  shall be binding on the Company (a) one (1) of whom shall be
                  selected by the Employee, (b) one (1) of whom shall be
                  selected by the Company and (c) the remaining one (1) of whom
                  shall be selected by the Qualified Physicians selected by the

                  this proviso and the fees and expenses of whom will be shared
                  and paid in equal amounts by the Employee and the Company, if:
                  (1)(A) the Company has reasonably withheld its consent to the
                  Qualified Physician, if any, selected by the Employee or (B)
                  the Employee has reasonably withheld his consent to the
                  Qualified Physician, if any, selected by the Company and (2)
                  the Qualified Physicians selected by the Employee and the
                  Company disagree as to whether the Employee has incurred a
                  Disability. For purposes of this definition, if the Employee
                  is unable by reason of illness or injury to give an informed
                  consent to the performance of the treatment of that illness or
                  injury, a Qualified Physician selected by any Person who is

                  state without a personal income tax on the date hereof which

                  Employee relocates from a state without a personal income tax
                  to a state having a personal income tax and the highest rate
                  of that tax is six percent (6%) when the Base Salary is
                  $200,000, then the Base Salary will be increased by $8,400
                  (computed at 70% x 6% x $200,000); provided, however, that the
                  obligation of the Company to pay the Base Salary earned by the

                  (c) such other date as the Board in its sole discretion may
                  determine shall be deferred to the last day of that period in
                  such amounts as the Board in its sole discretion may from time
                  to time determine, on which day the Company shall pay in full
                  to the Employee, without interest, the aggregate earned but
                  unpaid amount of the Base Salary for that period. Effective as
                  of the Separation Effective Date, the Base Salary theretofore
                  in effect shall be adjusted as provided in Section 5(E).

                  that are provided for hereunder to be paid to or for the
                  benefit of the Employee be determined or alleged to be subject
                  to an excise or similar purpose tax pursuant to Section 4999
                  of the Code, or any successor or other comparable federal,
                  state or local tax law by reason of being a "parachute
                  payment" (within the meaning of Section 280G of the Code), the
                  Company shall pay to the Employee such additional compensation
                  as is necessary (after taking into account all federal, state
                  and local taxes payable by the Employee as a result of the
                  receipt of such additional compensation) to place the Employee
                  in the same after-tax position (including federal, state and
                  local taxes) he would have been in had no such excise or
                  similar purpose tax (or interest or penalties thereon) been
                  paid or incurred. The Company hereby agrees to pay such
                  additional compensation within the earlier to occur of (i)
                  five (5) business days after the Employee notifies the Company
                  that the Employee intends to file a tax return taking the
                  position that such excise or similar purpose tax is due and
                  payable in reliance on a written opinion of the Employee's tax
                  counsel (such tax counsel to be chosen solely by the Employee)
                  that it is more

                                       11
<PAGE>
                  likely than not that such excise tax is due and payable or
                  (ii) twenty-four (24) hours of any notice of or action by the
                  Company that it intends to take the position that such excise
                  tax is due and payable. The costs of obtaining the tax counsel
                  opinion referred to in clause (i) of the preceding sentence
                  shall be borne by the Company, and as long as such tax counsel
                  was chosen by the Employee in good faith, the conclusions
                  reached in such opinion shall not be challenged or disputed by
                  the Company. If the Employee intends to make any payment with
                  respect to any such excise or similar purpose tax as a result
                  of an adjustment to the Employee's tax liability by any
                  federal, state or local tax authority, the Company will pay
                  such additional compensation by delivering its cashier's check
                  payable in such amount to the Employee within five (5)
                  business days after the Employee notifies the Company of his
                  intention to make such payment. Without limiting the
                  obligation of the Company hereunder, the Employee agrees, in
                  the event the Employee makes any payment pursuant to the
                  preceding sentence, to negotiate with the Company in good
                  faith with respect to procedures reasonably requested by the
                  Company which would afford the Company the ability to contest
                  the imposition of such excise or similar purpose tax;
                  provided, however, that the Employee will not be required to
                  afford the Company any right to contest the applicability of
                  any such excise or similar purpose tax to the extent that the
                  Employee reasonably determines (based upon the opinion of his
                  tax counsel) that such contest is inconsistent with the
                  overall tax interests of the Employee.

      5.    TERMINATION, SEPARATION PERIOD, DISABILITY AND DEATH

            A.    TERMINATION OF EMPLOYMENT BY THE COMPANY.

                  (i) The Company shall be entitled, if acting at the direction
                  of the Required Board Majority, to terminate the Employee's
                  Employment (a) at any time for Cause or (b) subject to the
                  payments obligations of the Separation Period, at any time
                  without Cause. The Company's termination of the Employee's
                  Employment hereunder will be effective on the date the Company
                  delivers a Notice of Termination for Cause to the Employee
                  pursuant hereto. Subject to the payment provisions applicable
                  to the Separation Period, the Employee shall be required to
                  vacate the premises of the Company, with all of the Employee's
                  personal property no later than five (5) business days after
                  the Notice of Termination.

                  (ii) If the Company terminates the Employee's Employment for
                  Cause,

                                       12
<PAGE>
                  the Company promptly thereafter, and in any event within five
                  (5) business days thereafter, shall pay the Employee his Base
                  Salary to and including the the end of the calendar month of
                  the Termination Date and the amount of all compensation
                  previously deferred by the Employee (together with any accrued
                  interest or earnings thereon), in each case to the extent not
                  theretofore paid, and, when that payment is made, the Company
                  shall, notwithstanding Section 3, have no further or other
                  obligations hereunder to the Employee.

                  (iii) If the Company otherwise terminates the Employee's
                  Employment, the respective rights and obligations of the
                  Company and the Employee during the Separation Period will be
                  as set forth in Section 5(E).

            B.    TERMINATION OF EMPLOYMENT BY THE EMPLOYEE.

                  (i) The Employee shall be entitled to terminate his
                  Employment, other than for Disability, at any time after one
                  hundred eighty (180) days after a Notice of Termination, (b)
                  by reason of a Change of Control at any time within three
                  hundred sixty-five (365) days after that Change of Control
                  occurs, or (c) at any time after thirty (30) days after
                  receipt of a Notice of Termination for material breach of any
                  provision of this Agreement, and the Company has not cured
                  that breach during the thirty (30) day period. The Employee's
                  termination of his Employment by reason of a Change of Control
                  will be effective on the first date on which the Change of
                  Control Payment shall have been paid in full to the Employee.
                  The Employee's termination of his Employment pursuant to (a)
                  and (b) above shall be effective on the Termination Date,
                  subject to the payment obligations of the Company during the
                  Separation Period.

                  (ii) If the Employee terminates his Employment by reason of a
                  Change of Control, the Company shall pay to the Employee in a
                  cash lump sum within five (5) business days after the date the
                  Company receives the Employee's Notice of Termination by
                  reason of that Change of Control the amount equal to the sum
                  of (a) the portion of the Base Salary to and including the
                  Termination Date which has not yet been paid, (b) all
                  compensation previously deferred by the Employee (together
                  with any accrued interest and earnings thereon), (c) any
                  accrued but unpaid vacation pay and (d) the Change of Control
                  Payment.

                                       13
<PAGE>
                  (iii) If the Employee terminates his Employment, other than
                  for Disability, the Company shall pay to the Employee, in a
                  cash lump sum within five (5) business days after the
                  Termination Date, the amount equal to the sum of (a) the
                  portion of the Base Salary to and including the Termination
                  Date which has not yet been paid, (b) all compensation
                  previously deferred by the Employee (together with any accrued
                  interest and earnings thereon) which has not yet been paid,
                  (c) any accrued but unpaid vacation pay and (d) the amount
                  equal to fifty percent (50%) of the Base Salary being paid for
                  the calendar year in which the Company receives the Employee's
                  Notice of Termination, and other than for Disability.

            C.    TERMINATION BY REASON OF DISABILITY. If the Employee incurs
                  any Disability during the term hereof, either the Employee or
                  the Company may terminate the Employee's Employment effective
                  on the third (3rd) anniversary of the date the Nonterminating
                  Party receives a Notice of Termination from the Terminating
                  Party pursuant to this Section 5(C). If the Employee's
                  Employment is terminated by reason of the Employee's
                  Disability, the respective rights and obligations of the
                  Company and the Employee during the Separation Period will be
                  as set forth in Section 5(E).

            D.    TERMINATION OF EMPLOYMENT BY DEATH. The Employee's Employment
                  shall terminate during the term hereof automatically at the
                  time of his death. If the Employee's Employment is terminated
                  by reason of the Employee's death, the Company shall pay to
                  the Person the Employee has designated in a written notice
                  delivered to the Company as his beneficiary entitled to such
                  payment, if any, or to the Employee's estate, as applicable,
                  in a cash lump sum within thirty (30) days after the
                  Termination Date, the amount equal to the sum of (i) the
                  portion of the Base Salary through the end of the month in
                  which the Termination Date occurs which has not yet been paid,
                  (ii) all compensation previously deferred by the Employee
                  (together with any accrued interest or earnings thereon) which
                  has not yet been paid, (iii) any accrued but unpaid vacation
                  pay and (iv) (a) the product of the Base Salary being paid for
                  the calendar year of death multiplied by three (3).

            E.    EMPLOYEE'S PAYMENT RIGHTS DURING THE SEPARATION PERIOD.

                  (i) The Company shall pay the Employee a Base Salary, in the
                  intervals consistent with the Company's normal payroll
                  schedules (but in no event less frequently than semi-monthly)
                  from the Separation Effective Date to and including the third
                  anniversiary thereof in the amounts determined from time to
                  time as follows: the Base Salary payable by the Company to the
                  Employee shall be as follows:

                        (a) if the Separation Effective Date occurs as a result
                        of the receipt by the Nonterminating Party of a Notice
                        of Termination other than for Cause, the amount equal to
                        the Average Annual Cash Compensation of the Employee
                        determined as of the Separation Effective Date; and (b)
                        if the Separation Effective Date occurs as a result of
                        the receipt by the Nonterminating Party of a Notice of
                        Termination for Disability pursuant to Section 5(C), the
                        amount equal to the amount by which (1) seventy-five
                        percent (75%) of the Average Annual Cash Compensation of
                        the Employee determined as of the Part-time Employment
                        Effective Date exceeds (2) the aggregate amount of
                        periodic payments the Employee receives during the
                        thirty-six (36) months beginning on that date under
                        Compensation Plans then in effect and providing for the
                        payment to the Employee solely as a result or on account
                        of disability; and

                        (b) on the first and each subsequent anniversary of the
                        Separation Date, the Base Salary payable pursuant to
                        this Section 5(E) shall be increased (but not decreased)
                        by the same percentage increase (if any) in the CPI for
                        the twelve (12) month period immediately preceding that
                        anniversary.

            (ii)  (a) The Employee shall continue to participate in all
                  Compensation Plans from time to time in effect during the
                  Separation Period, provided, however, that: (1) the Employee
                  shall not be entitled to receive any new award or grant under
                  any incentive plan, and any such new award or grant shall be
                  at the sole discretion of the Compensation Committee or the
                  Board, as applicable, with respect to that incentive plan; and
                  (2) if (A) the terms of any such plan preclude the Employee's
                  continued

                                       15
<PAGE>
                  participation therein or (B) his continued participation in
                  any such plan would or reasonably could be expected to
                  disqualify that plan under the Code, the Employee shall not be
                  entitled to participate in that plan, but the Company instead
                  shall provide the Employee with the after-tax equivalent of
                  the benefits that would have been provided to the Employee
                  were a participant in that plan.

                  (b)   For purposes of determining eligibility (including years
                        of service) for retirement benefits payable under any
                        Compensation Plan, the Employee shall be deemed to have
                        retired at the Termination Date.

                  (iii) Subject to the provisions of Section 7, the Employee
                  shall not be prevented from accepting other employment or
                  engaging in (and devoting substantially all his time to) other
                  business activities and shall not be required to perform any
                  regular duties for the Company, and the Employee may seek or
                  accept additional employment with any other Person. If the
                  Employee, at his discretion, shall accept any such additional
                  employment or engage in any such other business activity there
                  shall be no offset, reduction or effect upon any rights,
                  benefits or payments to which the Employee is entitled
                  pursuant to this Agreement. Furthermore, the Employee shall
                  have no obligation to account for, remit, rebate or pay over
                  to the Company any compensation or other amounts earned or
                  derived in connection with such additional employment or
                  business activity.

                        The Employee shall, however, make himself generally
                  available for special projects or to consult with the Company
                  and its employees at such times and at such places as may be
                  reasonably requested by the Company and which shall be
                  reasonably satisfactory to the Employee and consistent with
                  the Employee's regular duties and responsibilities in the
                  course of his then new occupation or other employment, if any.

                  (iv) Unless and until the Employee shall have sustained a
                  Disability, the Company shall continue to provide the Employee
                  with either the same or, at the Company's election, at a
                  different location within thirty-five (35) miles of the
                  Employee's principal residence, in any case reasonably
                  acceptable to the Employee, alternate but comparable office
                  space, furnishings, facilities, reserved parking, supplies,
                  services, equipment, secretarial and administrative assistance
                  that are in each case at least

                                       16
<PAGE>
                  commensurate with the size and quality of that which were
                  provided to the Employee during the calendar year immediately
                  preceding the Separation Effective Date pursuant to Section
                  6(C), but in no event less than are being furnished or
                  provided on the date hereof. The Company and Employee may
                  mutually agree upon an equivalent monthly cash allowance in
                  lieu of the Employee being provided all or any part of these
                  items. (v) The Employee shall remain entitled to the benefits
                  of Section 4(C).

            F.    RETURN OF PROPERTY. On termination of the Employee's
                  Employment, however brought about, the Employee (or his
                  representatives) shall promptly deliver and return to the
                  Company all the Company's property that is in the possession
                  or under the control of the Employee.

            G.    STOCK OPTIONS. Notwithstanding any provision of this Agreement
                  to the contrary: (i) except in the case of a termination of
                  the Employee's Employment for Cause, all stock options
                  previously granted to the Employee under incentive plans that
                  have not been exercised and are outstanding as of the time
                  immediately prior to the Termination Date shall,
                  notwithstanding any contrary provision of any applicable
                  incentive plan, remain outstanding (and continue to become
                  exercisable pursuant to their respective terms) until
                  exercised or the expiration of their term, whichever is
                  earlier; and (ii) in the case of a termination of the
                  Employee's Employment for Cause, all stock options previously
                  granted to the Employee under incentive plans that have not
                  been exercised and are outstanding as of the time immediately
                  prior to the Termination Date shall, notwithstanding any
                  contrary provision of any applicable incentive plan, remain
                  outstanding and continue to be exercisable until exercised or
                  the date that is ten (10) days after the Termination Date,
                  whichever is earlier. No stock option previously granted to
                  the Employee under any incentive plan shall, notwithstanding
                  any contrary provision of that incentive plan, expire or fail
                  to become exercisable or, if exercisable, cease to be
                  exercisable by reason of the occurrence of the Employee's
                  Separation Effective Date.

      6.    OTHER EMPLOYEE IGHTS

            A.    PAID VACATION; HOLIDAYS. The Employee shall be entitled to not
                  less than four (4) weeks of annual vacation and all legal
                  holidays during which times his applicable compensation shall
                  be paid in full. Further, it

                                       17
<PAGE>
                  is understood by the Employee that all paid vacation days
                  shall be taken by or on December 31 of the calender year. Any
                  and all vacation days which were not taken by said date, shall
                  be paid to the Employee on the second pay period of the
                  following January.

            B.    BUSINESS EXPENSES. The Employee is authorized to incur, and
                  will be entitled to receive prompt reimbursement for, all
                  reasonable expenses incurred by the Employee in performing his
                  duties and carrying out his responsibilities hereunder,
                  including business meal, entertainment and travel expenses,
                  provided that the Employee complies with the applicable
                  policies, practices and procedures of the Company relating to
                  the submission of expense reports, receipts or similar
                  documentation of those expenses. The Company shall either pay
                  directly or promptly reimburse the Employee for such expenses
                  not more than twenty (20) days after the submission to the
                  Company by the Employee from time to time of an itemized
                  accounting of such expenditures for which direct payment or
                  reimbursement is sought. Unpaid reimbursements after such
                  twenty (20) day period shall accrue interest in accordance
                  with Section 9(K).

            C.    SUPPORT. During the term hereof, the Employee shall be
                  provided by the Company with office space, furnishings, and
                  facilities, reserved parking, secretarial and administrative
                  assistance, supplies and other support equipment (including a
                  computer, facsimile machine and photocopier). .

      7.    COVENANT NOT TO COMPETE

            A.    The Employee recognizes that in each of the highly competitive
                  businesses in which the Company is engaged, personal contact
                  is of primary importance in securing new orthodontic practices
                  and in retaining the accounts and goodwill of present
                  practices and protecting the business of the Company. The
                  Employee, therefore, agrees that during the term of Employment
                  and for a period of one (1) year after the Termination Date,
                  Employee will not, within fifty (50) miles of the corporate
                  headquarters: (i) accept employment or render service to any
                  Person that is engaged in a business directly competitive with
                  the business then engaged in by the Company or (ii) enter into
                  or take part in or lend Employee's name, counsel or assistance
                  to any business, either as proprietor, principal, investor,
                  partner, director, officer, employee, consultant, advisor,
                  agent,

                                       18
<PAGE>
                  independent contractor, or in any other capacity whatsoever,
                  for any purpose that would be competitive with the business of
                  the Company.

            B.    If the provisions of this Section 7 are violated in any
                  material respect, the Company shall be entitled, upon
                  application to any court of proper jurisdiction, to a
                  temporary restraining order or preliminary injunction (without
                  the necessity of posting any bond with respect thereto) to
                  restrain and enjoin the Employee from that violation. If the
                  provisions of this Section 7 should ever be deemed to exceed
                  the time, geographic or occupational limitations permitted by
                  the applicable law, the Employee and the Company agree that
                  such provisions shall be and are hereby reformed to the
                  maximum time, geographic or occupational limitations permitted
                  by the applicable law.

      8.    CONFIDENTIAL INFORMATION

            A.    The Employee acknowledges that the Employee has had and will
                  continue to have access to various Confidential Information.
                  The Employee agrees, therefore, that Emp oyee will not at any
                  time, either while employed by the Company or afterwards,
                  knowingly make any independent use of, or knowingly disclose
                  to any other person (except as authorized by the Company) any
                  Confidential Information. Confidential Information shall not
                  include (i) information that becomes known to the public
                  generally through no fault of the Employee, (ii) information
                  required to be disclosed by law or legal process or the order
                  of any governmental authority under color of law, provided,
                  that prior to disclosing any information pursuant to this
                  clause (ii), the Employee shall, if possible, give prior
                  written notice thereof to the Company and provide the Company
                  with the opportunity to contest such disclosure, or (iii) the
                  Employee reasonably believes that such disclosure is required
                  in connection with the defense of a lawsuit against the
                  Employee. In the event of a breach or threatened breach by the
                  Employee of the provisions of this Section 8(A) with respect
                  to any Confidential Information, the Company shall be entitled
                  to a temporary restraining order and a preliminary and
                  permanent injunction (without the necessity of posting any
                  bond in connection therewith) restraining the Employee from
                  disclosing, in whole or in part, that Confidential
                  Information. Nothing herein shall be construed as prohibiting
                  the Company from pursuing any other available remedy for that
                  breach or threatened breach, including the recovery of
                  damages.

                                       19
<PAGE>
            B.    The Employee shall disclose promptly to the Company any and
                  all conceptions and ideas for inventions, improvements, and
                  valuable discoveries, whether patentable or not, which are
                  conceived or made by the Employee solely or jointly with any
                  other Person or Persons during the term of Employment and
                  which pertain primarily to the material business activities of
                  the Company, and the Employee hereby assigns and agrees to
                  assign all his interests therein to the Company or to its
                  nominee; whenever requested to do so by the Company, the
                  Employee shall execute any and all applications, assignments
                  or other instruments which the Company shall deem necessary to
                  apply for and obtain Letters of Patent of the United States or
                  any foreign country or to otherwise protect the Company's
                  interest therein. These obligations shall (i) continue beyond
                  the Termination Date with respect to inventions, improvements,
                  and valuable discoveries, whether patentable or not,
                  conceived, made or acquired by the Employee during the term of
                  Employment and (ii) be binding upon the Employee's assigns,
                  executors, administrators and other legal representatives.

      9.    GENERAL PROVISIONS

            A.    SEVERABILITY. If any one or more of the provisions of this
                  Agreement shall, for any reason, be held or found by final
                  judgment of a court of competent jurisdiction to be invalid,
                  illegal or unenforceable in any respect, (i) such invalidity,
                  illegality or unenforceability shall not affect any other
                  provisions of this Agreement, (ii) this Agreement shall be
                  construed as if such invalid, illegal or unenforceable
                  provision had never been contained herein (except that this
                  clause (ii) shall not prohibit any modification allowed under
                  Section 7(B)), and (iii) if the effect of a holding or finding
                  that any such provision is invalid, illegal or unenforceable
                  is to modify to the Employee's detriment, reduce or eliminate
                  any compensation, reimbursement, payment, allowance or other
                  benefit to the Employee intended by the Company and Employee
                  in entering into this Agreement, the Company shall, within
                  thirty (30) days after the date of such finding or holding,
                  negotiate and expeditiously enter into an agreement with the
                  Employee which contains alternative provisions (reasonably
                  acceptable to the Employee) that will restore to the Employee
                  (to the extent lawfully permissible) substantially the same
                  economic, substantive and income tax benefits and legal rights
                  the Employee would have enjoyed had such provision been upheld
                  as legal, valid and enforceable.

                                       20
<PAGE>
            B.    NONEXCLUSIVITY OF RIGHTS. Nothing herein shall prevent or
                  limit the Employee's continuing or future participation in any
                  Compensation Plan or, subject to Section 9(N), limit or
                  otherwise affect such rights as the Employee may have under
                  any other contract or agreement with the Company. Vested
                  benefits and other amounts to which the Employee is or becomes
                  entitled to receive under any Compensation Plan on or after
                  the Termination Date shall be payable in accordance with that
                  Compensation Plan, except as expressly modified hereby.

            C.    FULL SETTLEMENT. The Company's obligations to make the
                  payments provided for in, and otherwise to perform its
                  undertakings in, this Agreement shall not be affected by any
                  right of set-off, counterclaim, recoupment, defense or other
                  action, claim or right the Company may have against the
                  Employee or others. In no event shall the Employee be
                  obligated to seek other employment or take any other action by
                  way of mitigation of the amounts payable to the Employee under
                  any provision hereof, and those amounts shall not be reduced,
                  regardless of whether the Employee obtains other employment or
                  becomes self-employed.

            D.    SUCCESSORS.

                  (i) This Agreement is personal to the Employee and, without
                  the prior written consent of the Company, is not assignable by
                  the Employee otherwise than by will or the laws of descent and
                  distribution. This Agreement shall inure to the benefit and be
                  enforceable by the Employee's legal representatives acting in
                  their capacities as such pursuant to applicable law.

                  (ii) This Agreement shall inure to the benefit of and be
                  binding upon the Company and its successors and assigns. If
                  the Employee is not an Executive Officer, but is an officer of
                  a subsidiary of the Company, the Company shall be entitled to
                  assign all its obligations hereunder to that subsidiary and
                  treat the Employee as an employee of that subsidiary for all
                  purposes, but the Company shall remain liable for the full,
                  timely performance of all the obligations so assigned as if
                  the assignment had not been made.

                  (iii) The Company shall require any successor (direct or
                  indirect and whether by purchase, merger, consolidation, share
                  exchange or otherwise) to the business, properties and assets
                  of the Company substantially as an

<PAGE>
                  entirety expressly to assume and agree to perform this
                  Agreement in the same manner and to the same extent the
                  Company would have been required to perform it had no such
                  succession taken place.

            E.    AMENDMENTS; WAIVERS. This Agreement may not be amended or
                  modified except by a written agreement executed and delivered
                  by the parties hereto or their respective successors or legal
                  representatives acting in their capacities as such pursuant to
                  applicable law.

                  shall not be deemed a waiver of that provision or of any other
                  provision of or right under this Agreement.

            M.    TAX WITHHOLDING. Notwithstanding any other provision hereof,
                  the Company may withhold from amounts payable hereunder all
                  Federal, state, local and foreign taxes that are required to
                  be withheld by applicable laws or regulations.

            N.    ENTIRE AGREEMENT. Except for the Consulting Contract ratified
                  hereby and the agreements related to the IPO, including the
                  Plan and Agreement of Merger, the Company and the Employee (i)
                  acknowledge that this Agreement supersedes all prior written
                  and oral agreements between them with respect to the
                  employment of the Employee by the Company.

      10.   INTENDED BENEFITS TO EMPLOYEE; PAYMENT OF EXPENSES; RESOLUTION OF
            DISPUTES

            A.    INTENDED BENEFITS; PAYMENT OF EXPENSES. In entering into this
                  Agreement the Company intends that the Employee receive
                  without reduction or delay all the intended benefits of this
                  Agreement and that those benefits, and the terms and
                  conditions hereof, be construed in a manner most favorable to
                  the Employee; the Company, therefore, agrees that it will
                  strive expeditiously and in good faith to construe and resolve
                  in the Employee's favor and to his benefit any ambiguities or
                  uncertainties that may be created by the express language
                  hereof. If, however, at any time during the term hereof or
                  afterwards: (i) there should exist a dispute or conflict
                  between the Employee and the Company or another Person as to
                  the validity, interpretation or application of any term or
                  condition hereof, or as to the Employee's entitlement to any
                  benefit intended to be bestowed hereby, which is not resolved
                  to the satisfaction of the Employee, (ii) the Employee must
                  (a) defend the validity of this Agreement, (b) contest any
                  determination by the Company concerning the amounts payable
                  (or reimbursable) by the Company to the Employee, or (c)
                  determine in any tax year of the Employee the tax consequences
                  to the Employee of any amounts payable (or reimbursable) under
                  Section 4(c) or 4(B)(iii), or (iii) the Employee must prepare
                  responses to an Internal Revenue Service ("IRS") audit of, or
                  otherwise defend, his personal income tax return for any year
                  the subject of any such audit, or an adverse determination,
                  administrative proceedings or civil litigation arising
                  therefrom that is occasioned by or related to an audit by the
                  IRS of the Company's income tax returns, then the Company
                  hereby unconditionally agrees: (a) on written demand of the
                  Company by the Employee, to

                                       24
<PAGE>
                  provide sums sufficient to advance and pay on a current basis
                  (either by paying directly or by reimbursing the Employee) not
                  less than thirty (30) days after a written request therefor is
                  submitted by the Employee, the Employee's out of pocket costs
                  and expenses (including attorney's fees, expenses of
                  investigation, travel, lodging, copying, delivery services and
                  disbursements for the fees and expenses of experts, etc.)
                  incurred by the Employee in connection with any such matter;
                  (b) the Employee shall be entitled, upon application to any
                  court of competent jurisdiction, to the entry of a mandatory
                  injunction without the necessity of posting any bond with
                  respect thereto which compels the Company to pay or advance
                  such costs and expenses on a current basis; and (c) the
                  company's obligations under this Section 10(A) will not be
                  affected if the Employee is not the prevailing party in the
                  final resolution of any such matter.

      11.   INDEMNIFICATION

Pursuant to the express terms and conditions of the Certificate of Incorporation
and Bylaws of the Company, the Company hereby ratify and confirm and enter into
an express separate contract to provide that the Employee shall be held harmless
from monetary damages and be fully indemnified by the Company to the maximum
extent permitted by the law of Delaware, the state of the Company's
incorporation, and the law of the state of incorporation of any subsidiary of
the Company of which the Employee is a director or an officer or employee, as
the same may be in effect from time to time.

                              EMPLOYMENT AGREEMENT

      THIS EMPLOYMENT AGREEMENT (this "Agreement"), is entered into on December
9, 1996, by and between APPLE ORTHODONTIX, INC., a Delaware corporation (the
"Company") and ROBERT J. SYVERSON (the "Employee").

                                R E C I T A L S:

      In entering into this Agreement, the Company desires to provide the
Employee with substantial incentives to serve the Company as a senior executive
performing at the highest levels of leadership and stewardship, without
distraction or concern over minimum compensation, benefits or tenure, to develop
and implement the Company's initial development plan and thereafter assist in
managing the Company's future growth and development and maximizing the returns
to the Company's stockholders. Further, the Employee understands and agrees that
prior to the Effective Date, he shall work on behalf of Apple as a full-time
consultant.

      NOW, THEREFORE, in consideration of the foregoing and the mutual
provisions contained herein, and for other good and valuable consideration, the
parties hereto agree with each other as follows:

      1.    CERTAIN DEFINITIONS

            A.    CERTAIN DEFINITIONS. As used herein, the following terms have
                  the meanings assigned to them below:

                  "ACQUIRING PERSON" means any Person who or which, together
                  with all Affiliates and Associates of such Person, is or are
                  the Beneficial Owner of twenty-five percent (25%) or more of
                  the shares of Common Stock then outstanding, but does not
                  include any Exempt Person; provided, however, that a Person
                  shall not be or become an Acquiring Person if such Person,
                  together with its Affiliates and Associates, shall become the
                  Beneficial Owner of twenty-five percent (25%) or more of the
                  shares of Common Stock then outstanding solely as a result of
                  a reduction in the number of shares of Common Stock
                  outstanding due to the repurchase of Common Stock by the
                  Company, unless and until such time as such Person or any
                  Affiliate or Associate of such Person shall purchase or
                  otherwise become the Beneficial Owner of additional shares of
                  Common Stock constituting one percent (1%) or more of the then
                  outstanding shares of Common Stock or any other Person (or
                  Persons) who is (or collectively are) the Beneficial Owner of
                  shares of Common Stock constituting one percent (1%) or more
                  of the then outstanding shares of Common Stock shall become an
                  Affiliate or Associate of such Person, unless, in either such
                  case, such Person, together with all Affiliates and
<PAGE>
                  Associates of such Person, is not then the Beneficial Owner of
                  twenty-five percent (25%) or more of the shares of Common
                  Stock then outstanding.

                  "ACTIVE STATUS" means the Employee's Employment status from

                  the Part-time Employment Effective Date or (b) the Termination
                  Date.

                  "AFFILIATE" has the meaning ascribed to that term in Exchange
                  Act Rule 12b-2.

                  "ANNUAL CASH COMPENSATION" of the Employee for any

                  amounts deferred at the election of the Employee pursuant to a
                  Compensation Plan intended to qualify as a plan under Section
                  401(k) of the Code or otherwise. If salary or bonus is paid in
                  whole or in part in property other than cash (such as Common
                  Stock) the amount so paid shall be the fair market value
                  thereof on the date of payment.

                  "ASSOCIATE" means, with reference to any Person, (a) any
                  corporation, firm, partnership, association, unincorporated
                  organization or other entity (other than the Company or a
                  subsidiary of the Company) of which that Person is an officer
                  or general partner (or officer or general partner of a general
                  partner) or is, directly or indirectly, the Beneficial Owner
                  of 10% or more of any class of its equity securities, (b) any
                  trust or other estate in which that Person has a substantial
                  beneficial interest or for or of which that Person serves as
                  trustee or in a similar fiduciary capacity and (C) any
                  relative or spouse of that Person, or any relative of that
                  spouse, who has the same home as that Person.

                  "AVERAGE ANNUAL CASH COMPENSATION" of the Employee
                  means, as of the Part-time Employment Effective Date, the
                  average of (a) the Annual Cash Compensation earned by the
                  Employee in each of the two (2) Compensation Years next
                  preceding that date or, if less than two (2) Compensation
                  Years have occurred prior to that date and since the Effective
                  Date, (b) the Annual Cash Compensation in each whole
                  Compensation Year, if any, and, restated on an annualized
                  basis, the Annual Cash Compensation in each partial
                  Compensation Year (up to a maximum of two (2) partial
                  Compensation Years) next preceding the Part-time Employment
                  Effective Date.

                  "BASE SALARY" means: (a) prior to the Part-time Employment
                  Effective Date, the guaranteed minimum annual salary payable
                  by the Company to the Employee pursuant to Section 4(A); and
                  (b) on and after

                                        2

                  minimum annual salary payable by the Company to the Employee
                  pursuant to Section 5(E).

                  A specified Person is deemed the "BENEFICIAL OWNER" of, and is
                  deemed to "beneficially own," any securities:

                        (a) of which that Person or any of that Person's
                  Affiliates or Associates, directly or indirectly, is the
                  "beneficial owner" (as determined pursuant to Exchange Act
                  Rule 13d-3) or otherwise has the right to vote or dispose of,
                  including pursuant to any agreement, arrangement or
                  understanding (whether or not in writing); provided, however,
                  that a Person shall not be deemed the "Beneficial Owner" of,
                  or to "beneficially own," any security under this subparagraph
                  (a) as a result of an agreement, arrangement or understanding
                  to vote that security if that agreement, arrangement or
                  understanding: (1) arises solely from a revocable proxy or
                  consent given in response to a public (that is, not including
                  a solicitation exempted by Exchange Act Rule 14a-2(b)(2))
                  proxy or consent solicitation made pursuant to, and in
                  accordance with, the applicable provisions of the Exchange
                  Act; and (2) is not then reportable by such Person on Exchange
                  Act Schedule 13D (or any comparable or successor report);

                        (b) which that Person or any of that Person's Affiliates
                  or Associates, directly or indirectly, has the right or
                  obligation to acquire (whether that right or obligation is
                  exercisable or effective immediately or only after the passage
                  of time or the occurrence of an event) pursuant to any
                  agreement, arrangement or understanding (whether or not in
                  writing) or on the exercise of conversion rights, exchange
                  rights, other rights, warrants or options, or otherwise;
                  provided, however, that a Person shall not be deemed the
                  "Beneficial Owner" of, or to "beneficially own," securities
                  tendered pursuant to a tender or exchange offer made by that
                  Person or any of that Person's Affiliates or Associates until
                  those tendered securities are accepted for purchase or
                  exchange; or

                        (c) which are beneficially owned, directly or
                  indirectly, by (1) any other Person (or any Affiliate or
                  Associate thereof) with which the specified Person or any of
                  the specified Person's Affiliates or Associates has any
                  agreement, arrangement or understanding (whether or not in
                  writing) for the purpose of acquiring, holding, voting (except
                  pursuant to a revocable proxy or consent as described in the
                  proviso to subparagraph (a) of this definition) or disposing
                  of any voting securities of the Company or (2) any group (as
                  that term is used in Exchange Act Rule 13d-5(b)) of which that
                  specified Person is a member; provided, however, that nothing
                  in this definition shall cause a Person engaged in business as
                  an underwriter of securities to be the "Beneficial Owner" of,
                  or to

                                        3
<PAGE>
                  "beneficially own," any securities acquired through such
                  Person's participation in good faith in a firm commitment
                  underwriting until the expiration of forty (40) days after the
                  date of that acquisition. For purposes of this Agreement,
                  "voting" a security shall include voting, granting a proxy,
                  acting by consent, making a request or demand relating to
                  corporate action (including, without limitation, calling a
                  stockholder meeting) or otherwise giving an authorization
                  (within the meaning of Section 14(a) of the Exchange Act) in
                  respect of such security. "BOARD" means the entire Board of
                  Directors of the Company.

                  "BUSINESS REASON" for the Company's termination of the
                  Employee's Employment means any lawful reason other than
                  Cause.

                  "CAUSE" for the Company's termination of the Employee's
                  Employment means: (a) the Employee's final conviction of a
                  felony crime that enriched the Employee at the expense of the
                  Company; or (b) the Employee's deliberate and intentional
                  continuing failure to substantially perform his duties and
                  responsibilities hereunder (except by reason of the Employee's
                  incapacity due to physical or mental illness or injury) for a
                  period of forty-five (45) days after the Required Board
                  Majority has delivered to the Employee a written demand for
                  substantial performance hereunder which specifically
                  identifies the bases for the Required Board Majority's
                  determination that the Employee has not substantially
                  performed his duties and responsibilities hereunder (such
                  period being the "Grace Period"); provided, that for purposes
                  of this clause (b), the Company shall not have Cause to
                  terminate the Employee's Employment unless (1) at a meeting of
                  the Board called and held following the Grace Period in the
                  city in which the Company's principal executive offices are
                  located of which the Employee was given not less than ten (10)
                  days' prior written notice and at which the Employee was
                  afforded the opportunity to be represented by counsel, appear
                  and be heard, the Required Board Majority shall adopt a
                  written resolution which (A) sets forth the Required Board
                  Majority's determination that the failure of the Employee to
                  substantially perform his duties and responsibilities
                  hereunder has (except by reason of his incapacity due to
                  physical or mental illness or injury) continued past the Grace
                  Period and (B) specifically identifies the bases for that
                  determination and (2) the Company, at the written direction of
                  the Required Board Majority, shall deliver to the Employee a
                  Notice of Termination for Cause to which a copy of that
                  resolution, certified as being true and correct by the
                  secretary or any assistant secretary of the Company, is

      2.    EMPLOYMENT

            A.    On the terms and subject to the conditions hereinafter set
                  forth, and beginning as of the Effective Date, the Company
                  will employ the Employee as its President and the Employee
                  will serve in the Company's employ in that position. The
                  Employee shall perform such duties, and have such powers,
                  authority, functions, duties and responsibilities for the
                  Company and corporations affiliated with the Company as are
                  commensurate and consistent with his employment as the
                  Company's President. The Employee also shall have such
                  additional powers, authority, functions, duties and
                  responsibilities as may be assigned to him by the Board;
                  provided that, without the Employee's written consent, such
                  additional powers, authority, functions, duties and
                  responsibilities shall not

                                       11
<PAGE>
                  be inconsistent or interfere with, or detract from, those
                  herein vested in, or otherwise then being performed for the
                  Company by the Employee.

            B.    The Employee shall not, at any time during his Employment,
                  engage in any other activities unless those activities do not
                  interfere materially with the Employee's duties and
                  responsibilities for the Company at that time, except that the
                  Employee shall be entitled, subject to the provisions of
                  Section 7, (a) to continue with such activities as the
                  Employee has carried on prior to the Effective Date, including
                  making and managing his personal investments and participating
                  in other business or civic activities and (b) to serve on
                  corporate or other business, civic or charitable boards or
                  committees and trade association or similar boards or
                  committees.

      3. TERM OF EMPLOYMENT. Subject to the provisions of Section 5, the term of
the Employee's Employment shall be for a continually renewing term of three (3)
years commencing on the Effective Date and renewing each day thereafter for an
additional day without any further action by either the Company or the Employee,
it being the intention of the parties that there shall be continuously a
remaining term of three (3) years' duration of the Employee's Employment until
an event has occurred as described in, or one of the parties shall have made an
appropriate election pursuant to, the provisions of Section 5. When the
Termination Date shall have occurred and the Company shall have paid to the
Employee all the applicable amounts Section 5 provides the Company shall pay as
a result of the termination of the Employee's Employment, including all amounts
accruing during the Part-time Employment Period, if any, this Agreement will
terminate and have no further force or effect, except that Sections 4(C), 8, 9,
10 and 11 shall survive that termination indefinitely and Section 7 shall
survive for the period of time provided for therein.

      4.    COMPENSATION

            A.    BASE SALARY. A Base Salary shall be payable to the Employee by
                  the Company as a guaranteed minimum annual amount hereunder
                  for each Compensation Year during the period from the
                  Effective Date to the first to occur of the Part-time
                  Employment Effective Date or the Termination Date. That Base
                  Salary shall be payable in the intervals consistent with the
                  Company's normal payroll schedules (but in no event less
                  infrequently than semi-monthly), shall be payable initially at
                  the annual rate of $150,000 and shall be increased (but not
                  decreased or adjusted other than as provided in Section 5) as
                  follows:

                  (i) on the first and each subsequent anniversary of the
                  Effective Date, by the same percentage increase (if any) in
                  the CPI for the twelve (12) month period immediately preceding
                  such anniversary;

                  (ii) on the first and each subsequent anniversary of the
                  Effective Date, by such additional amount as shall be
                  determined in the sole discretion of

                                       12
<PAGE>
                  the Compensation Committee, but only in such form and to such
                  extent as the Compensation Committee may from time to time
                  approve, as evidenced by the written minutes or records of the
                  Compensation Committee and its written notices of such
                  determinations or approvals to the Employee; and

                  (iii) if the Employee relocates from a state without a
                  personal income tax at the time of his relocation to a state
                  having a personal income tax, or if the Employee resides in a
                  state without a personal income tax on the date hereof which
                  subsequently adopts a personal income tax, then, in either
                  case, the Base Salary in effect at the time of such relocation
                  or adoption, as applicable, shall immediately be increased by
                  the amount equal to the Base Salary immediately prior to this
                  increase multiplied by seventy percent (70%) of the highest
                  personal income tax rate of such state; for example, if the
                  Employee relocates from a state without a personal income tax
                  to a state having a personal income tax and the highest rate
                  of that tax is six percent (6%) when the Base Salary is
                  $200,000, then the Base Salary will be increased by $8,400
                  (computed at 70% x 6% x $200,000); provided, however, that the
                  obligation of the Company to pay the Base Salary earned by the
                  Employee for his service in the period beginning on the
                  Effective Date and ending on the date that is the first to
                  occur of (a) the IPO Closing Date, (b) the Termination Date or
                  (C) such other date as the Board in its sole discretion may
                  determine shall be deferred to the last day of that period in
                  such amounts as the Board in its sole discretion may from time
                  to time determine, on which day the Company shall pay in full
                  to the Employee, without interest, the aggregate earned but
                  unpaid amount of the Base Salary for that period. Effective as
                  of the Part-time Employment Effective Date, the Base Salary
                  theretofore in effect shall be adjusted as provided in Section
                  5(E).

            B.    OTHER COMPENSATION.

                  (I) The Employee shall be entitled to participate in all
                  Compensation Plans from time to time in effect while he
                  remains on Active Status, regardless of whether the Employee
                  is an Executive Officer. All awards to the Employee under all
                  Incentive Plans shall take into account the Employee's
                  positions with and duties and responsibilities to the Company
                  and its subsidiaries.

                  (ii) The Company shall grant to the Employee 40 shares of
                  it's pre- IPO common stock subject to a subscription
                  agreement.

                                       13

            C.    TAX INDEMNITY. Should any of the payments of Base Salary,
                  other incentive or supplemental compensation, benefits,
                  allowances, awards, payments, reimbursements or other
                  perquisites, or any other payment in the nature of
                  compensation, singly, in any combination or in the aggregate,
                  that are provided for hereunder to be paid to or for the
                  benefit of the Employee be determined or alleged to be subject
                  to an excise or similar purpose tax pursuant to Section 4999
                  of the Code, or any successor or other comparable federal,
                  state or local tax law by reason of being a "parachute
                  payment" (within the meaning of Section 280G of the Code), the
                  Company shall pay to the Employee such additional compensation
                  as is necessary (after taking into account all federal, state
                  and local taxes payable by the Employee as a result of the
                  receipt of such additional compensation) to place the Employee
                  in the same after-tax position (including federal, state and
                  local taxes) he would have been in had no such excise or
                  similar purpose tax (or interest or penalties thereon) been
                  paid or incurred. The Company hereby agrees to pay such
                  additional compensation within the earlier to occur of (I)
                  five (5) business days after the Employee notifies the Company
                  that the Employee intends to file a tax return taking the
                  position that such excise or similar purpose tax is due and
                  payable in reliance on a written opinion of the Employee's tax
                  counsel (such tax counsel to be chosen solely by the Employee)
                  that it is more likely than not that such excise tax is due
                  and payable or (ii) twenty-four (24) hours of any notice of or
                  action by the Company that it intends to take the position
                  that such excise tax is due and payable. The costs of
                  obtaining the tax counsel opinion referred to in clause (I) of
                  the preceding sentence shall be borne by the Company, and as
                  long as such tax counsel was chosen by the Employee in good
                  faith, the conclusions reached in such opinion shall not be
                  challenged or disputed by the Company. If the Employee intends
                  to make any payment with respect to any such excise or similar
                  purpose tax as a result of an adjustment to the Employee's tax
                  liability by any federal, state or local tax authority, the
                  Company will pay such additional compensation by delivering
                  its cashier's check payable in such amount to the Employee
                  within five (5) business days after the Employee notifies the
                  Company of his intention to make such payment. Without
                  limiting the obligation of the Company hereunder, the Employee
                  agrees, in the event the Employee makes any payment pursuant
                  to the preceding sentence, to negotiate with the Company in
                  good faith with respect to procedures reasonably requested by
                  the Company which would afford the Company the ability to
                  contest the imposition of such excise or similar purpose tax;
                  provided, however, that the Employee will not be required to
                  afford the Company any right to contest the applicability of
                  any such excise or similar purpose tax to the extent that the
                  Employee reasonably determines (based upon the opinion of his
                  tax counsel) that such contest is inconsistent with the
                  overall tax interests of the Employee.

      5.    TERMINATION, PART-TIME EMPLOYMENT PERIOD, DISABILITY AND

                  prior to the Part-time Employment Effective Date for Type II
                  Cause or for any Business Reason. If the Employee is neither a
                  member of the Board nor an Executive Officer, the Company
                  shall be entitled, if acting at the direction of the chief
                  executive officer of the Company, to terminate the Employee's
                  Employment at any time prior to the Part-time Employment Date
                  for any Business Reason. The Company's termination of the
                  Employee's Employment for Cause will be effective on the date
                  the Company delivers a Notice of Termination for Cause to the
                  Employee pursuant to this Section 5(A)(I)(together, in the
                  case of a termination for Type II Cause, with the certified
                  resolution referred to in clause (b) of the definition herein
                  of Cause), while the Company's termination of the Employee's
                  Employment for a Business Reason will be effective on the

                  pursuant to this Section 5(A)(I).

                  (ii) If the Company terminates the Employee's Employment for
                  Cause, the Company promptly thereafter, and in any event
                  within five (5) business days thereafter, shall pay the
                  Employee his Base Salary to and including the Termination Date
                  and the amount of all compensation previously deferred by the
                  Employee (together with any accrued interest or earnings
                  thereon), in each case to the extent not theretofore paid,
                  and, when that payment is made, the Company shall,
                  notwithstanding Section 3, have no further or other
                  obligations hereunder to the Employee.

                  (iii) If the Company terminates the Employee's Employment for
                  a Business Reason, the respective rights and obligations of
                  the Company and the Employee during the Part-time Employment
                  Period will be as set forth in Section 5(E).

            B.    TERMINATION OF EMPLOYMENT BY THE EMPLOYEE.

                  (i) The Employee shall be entitled to terminate his Employment
                  (a) for a Good Reason at any time within one hundred eighty
                  (180) days after the facts or circumstances constituting that
                  Good Reason first exist and are known to the Employee, (b) by
                  reason of a Change of Control at any time within three hundred
                  sixty-five (365) days after that Change of Control

                  of Control if it occurs (1) during the thirty (30) day period
                  following the Company's receipt of the Employee's Notice of
                  Termination without Good Reason and other than for Disability
                  pursuant to this Section 5(B)(I), (2) after (A) the receipt by
                  the Nonterminating Party of the Terminating Party's Notice of
                  Termination pursuant to Section 5 (C) or (B) the Employee's
                  receipt of the Company's Notice of Termination for a Business

                  sixty-five (365) days after the Company's receipt of the
                  Employee's Notice of Termination for Good Reason pursuant to
                  this Section 5(B)(I)) or (C) without Good Reason and other
                  than for Disability at any time. The Employee's termination of
                  his Employment for Good Reason will be effective on the third
                  (3rd) anniversary of the date the Employee delivers a Notice
                  of Termination for Good Reason to the Company pursuant to this
                  Section 5(B)(I). The Employee's termination of his Employment
                  by reason of a Change of Control will be effective on the
                  first date on which the Change of Control Payment shall have
                  been paid in full to the Employee. The Employee's termination
                  of his Employment without Good Reason and other than for
                  Disability will be effective on the thirtieth (30th) day
                  following the Employee's delivery of a Notice of Termination
                  without Good Reason and other than for Disability pursuant to
                  this Section 5(B)(I).

                  (ii) If the Employee terminates his Employment for Good
                  Reason, the respective rights and obligations of the Company
                  and the Employee during the Part-time Employment Period will
                  be as set forth in Section 5(E).

                  (iii) If the Employee terminates his Employment by reason of a
                  Change of Control, the Company shall pay to the Employee in a
                  cash lump sum within five (5) business days after the date the
                  Company receives the Employee's Notice of Termination by
                  reason of that Change of Control the amount equal to the sum
                  of (a) the portion of the Base Salary to and including the
                  Termination Date which has not yet been paid, (b) all
                  compensation previously deferred by the Employee (together
                  with any accrued interest and earnings thereon), (C) any
                  accrued but unpaid vacation pay and (d) the Change of Control
                  Payment.

                  (iv) If the Employee terminates his Employment without Good
                  Reason and other than for Disability, the Company shall pay to
                  the Employee, in a cash lump sum within five (5) business days
                  after the Termination Date, the amount equal to the sum of (a)
                  the portion of the Base Salary to and including the
                  Termination Date which has not yet been paid, (b) all
                  compensation previously deferred by the Employee (together
                  with any accrued interest and earnings thereon) which has not
                  yet been paid, (C) any

                                       16
<PAGE>
                  accrued but unpaid vacation pay and (d) the amount equal to
                  fifty percent (50%) of the Base Salary being paid for the
                  Compensation Year in which the Company receives the Employee's
                  Notice of Termination without Good Reason and other than for
                  Disability; provided, however, that if the Employee terminates
                  his Employment without Good Reason and other than for
                  Disability within six (6) months of the theretofore scheduled
                  final day of the Part-time Employment Period, the amount
                  payable pursuant to clause (d) of this sentence shall be the
                  amount determined pursuant to that clause multiplied by a
                  fraction the numerator of which is the number of days from and
                  excluding the date the Company receives the Notice of
                  Termination to and including that final day and the
                  denominator of which is one hundred eighty-two (182). For
                  purposes of this Section 5(B)(iv), if the anniversary of the
                  Effective Date in the Compensation Year in which the Company
                  receives the Notice of Termination without Good Reason and
                  other than for Disability has not occurred on or prior to the
                  date of that receipt, the Base Salary for that Compensation
                  Year will be calculated on the assumption that no increase in
                  the amount thereof would be made effective as of that
                  anniversary pursuant to Section 4(A) or 5(E)(I), as
                  applicable.

            C.    TERMINATION BY REASON OF DISABILITY. If the Employee incurs
                  any Disability while on Active Status, either the Employee or
                  the Company may terminate the Employee's Employment effective
                  on the third (3rd) anniversary of the date the Nonterminating
                  Party receives a Notice of Termination from the Terminating
                  Party pursuant to this Section 5(C). If the Employee's
                  Employment is terminated by reason of the Employee's
                  Disability, the respective rights and obligations of the
                  Company and the Employee during the Part-time Employment
                  Period will be as set forth in Section 5(E).

            D.    TERMINATION OF EMPLOYMENT BY DEATH.  The Employee's
                  Employment shall terminate automatically at the time of his
                  death. If the Employee's Employment is terminated by reason of
                  the Employee's death, the Company shall pay to the Person the
                  Employee has designated in a written notice delivered to the
                  Company as his beneficiary entitled to such payment, if any,
                  or to the Employee's estate, as applicable, in a cash lump sum
                  within thirty (30) days after the Termination Date, the amount
                  equal to the sum of (I) the portion of the Base Salary through
                  the end of the month in which the Termination Date occurs
                  which has not yet been paid, (ii) all compensation previously
                  deferred by the Employee (together with any accrued interest
                  or earnings thereon) which has not yet been paid, (iii) any
                  accrued but unpaid vacation pay (if the Employee dies while on
                  Active Status) and (iv) (a) if the Employee dies while on
                  Active Status, the product of (1) the Base Salary being paid
                  for the Compensation Year in which he dies multiplied by (2)
                  three (3) or (b) if the Employee dies

                                       17
<PAGE>
                  during the Part-time Employment Period, the product of (1)
                  one-twelfth (1/12th) of the Base Salary being paid for the
                  Compensation Year in which the Employee dies multiplied by (2)
                  the number of whole and partial calendar months in the period
                  beginning with the first calendar month after the calendar
                  month in which he dies and ending with the last calendar month
                  in which the Termination Date would have occurred if the
                  Employee's Employment were to have continued to the end of the
                  Part-time Employment Period. For purposes of this Section
                  5(D), if the anniversary of the Effective Date in the
                  Compensation Year in which the Employee dies has not occurred
                  on or before the Termination Date, the Base Salary for that
                  Compensation Year will be calculated on the assumption that no
                  increase in the amount thereof would be made effective as of
                  that anniversary pursuant to Section 4(A) or 5(E)(I), as
                  applicable.

            E.    EMPLOYEE'S RIGHTS DURING THE PART-TIME EMPLOYMENT
                  PERIOD.

                  (i) The Company shall pay the Employee a Base Salary, in the
                  intervals consistent with the Company's normal payroll
                  schedules (but in no event less frequently than semi-monthly)
                  from the Part-time Employment Effective Date to and including
                  the Termination Date in the amounts determined from time to
                  time as follows: Effective as of the Part-time Employment
                  Effective Date, the Base Salary payable by the Company to the
                  Employee for the period from and including that date to and
                  excluding the third (3rd) anniversary of that date shall be as
                  follows:

                        (a) if the Part-time Employment Effective Date occurs as
                        a result of the receipt by the Nonterminating Party of a
                        Notice of Termination for a Business Reason pursuant to
                        Section 5(A) or a Notice of Termination for Good Reason
                        pursuant to Section 5(B)(I), the amount equal to the
                        Average Annual Cash Compensation of the Employee
                        determined as of the Part-time Employment Effective
                        Date; and (b) if the Part-time Employment Effective Date
                        occurs as a result of the receipt by the Nonterminating
                        Party of a Notice of Termination for Disability pursuant
                        to Section 5(C), the amount equal to the amount by which
                        (1) seventy-five percent (75%) of the Average Annual
                        Cash Compensation of the Employee determined as of the
                        Part-time Employment Effective Date exceeds (2) the
                        aggregate amount of periodic payments the Employee
                        receives during the twelve (12) months beginning on that
                        date under Compensation Plans then in effect and
                        providing for the payment to the Employee solely as a
                        result or on account of disability; and

                                       18
<PAGE>
                        (b) on the first and each subsequent anniversary of the
                        Part-time Employment Effective Date, the Base Salary
                        payable pursuant to this Section 5(E) shall be increased
                        (but not decreased) by the same percentage increase (if
                        any) in the CPI for the twelve (12) month period
                        immediately preceding that anniversary.

                  (ii)  (a) The Employee shall continue to participate in all
                        Compensation Plans from time to time in effect during
                        the Part-time Employment Period, provided, however,
                        that: (1) the Employee shall not be entitled to receive
                        any new award or grant under any Incentive Plan, and any
                        such new award or grant shall be at the sole discretion
                        of the Compensation Committee or the Board, as
                        applicable, with respect to that Incentive Plan; and (2)
                        if (A) the terms of any such plan preclude the
                        Employee's continued participation therein or (B) his
                        continued participation in any such plan would or
                        reasonably could be expected to disqualify that plan
                        under the Code, the Employee shall not be entitled to
                        participate in that plan, but the Company instead shall
                        provide the Employee with the after-tax equivalent of
                        the benefits that would have been provided to the
                        Employee were he a participant in that plan.

                        (b) For purposes of determining eligibility (including
                        years of service) for retirement benefits payable under
                        any Compensation Plan, the Employee shall be deemed to
                        have retired at the Termination Date.

                  (iii) Subject to the provisions of Section 7, the Employee
                  shall not be (A) prevented from accepting other employment or
                  engaging in (and devoting substantially all his time to) other
                  business activities or (B) required to perform any regular
                  duties for the Company (except to provide such services
                  consistent with the Employee's educational background,
                  experience and prior positions with the Company as may be
                  acceptable to the Employee) or to seek or accept additional
                  employment with any other Person. If the Employee, at his
                  discretion, shall accept any such additional employment or
                  engage in any such other business activity there shall be no
                  offset, reduction or effect upon any rights, benefits or
                  payments to which the Employee is entitled pursuant to this
                  Agreement. Furthermore, the Employee shall have no obligation
                  to account for, remit, rebate or pay over to the Company any
                  compensation or other amounts earned or derived in connection
                  with such additional employment or business activity.

                        The Employee shall, however, make himself generally
                  available for special projects or to consult with the Company
                  and its employees at such

                                       19
<PAGE>
                  times and at such places as may be reasonably requested by the
                  Company and which shall be reasonably satisfactory to the
                  Employee and consistent with the Employee's regular duties and
                  responsibilities in the course of his then new occupation or
                  other employment, if any.

                  (iv) Unless and until the Employee shall have sustained a
                  Disability, the Company shall continue to provide the Employee
                  with either the same or, at the Company's election, at a
                  different location within thirty-five (35) miles of the
                  Employee's principal residence, in any case reasonably
                  acceptable to the Employee, alternate but comparable office
                  space, furnishings, facilities, reserved parking, supplies,
                  services, equipment, secretarial and administrative assistance
                  that are in each case at least commensurate with the size and
                  quality of that which were provided to the Employee during the
                  Compensation Year immediately preceding the Part-time
                  Employment Effective Date pursuant to Section 6(C), but in no
                  event less than are being furnished or provided on the date
                  hereof. The Company and Employee may mutually agree upon an
                  equivalent monthly cash allowance in lieu of the Employee
                  being provided all or any part of these items.

                  (v)   The Employee shall remain entitled to the benefits of
                  Section 4(C).

            F.    RETURN OF PROPERTY. On termination of the Employee's
                  Employment, however brought about, the Employee (or his
                  representatives) shall promptly deliver and return to the
                  Company all the Company's property that is in the possession
                  or under the control of the Employee.

            G.    STOCK OPTIONS. Notwithstanding any provision of this Agreement
                  to the contrary: (I) except in the case of a termination of
                  the Employee's Employment for Cause, all stock options
                  previously granted to the Employee under Incentive Plans that
                  have not been exercised and are outstanding as of the time
                  immediately prior to the Termination Date shall,
                  notwithstanding any contrary provision of any applicable
                  Incentive Plan, remain outstanding (and continue to become
                  exercisable pursuant to their respective terms) until
                  exercised or the expiration of their term, whichever is
                  earlier; and (ii) in the case of a termination of the
                  Employee's Employment for Cause, all stock options previously
                  granted to the Employee under Incentive Plans that have not
                  been exercised and are outstanding as of the time immediately
                  prior to the Termination Date shall, notwithstanding any
                  contrary provision of any applicable Incentive Plan, remain
                  outstanding and continue to be exercisable until exercised or
                  the date that is ten (10) days after the Termination Date,
                  whichever is earlier. No stock option previously granted to
                  the Employee under any Incentive Plan shall, notwithstanding
                  any contrary provision of that

                                       20
<PAGE>
                  Incentive Plan, expire or fail to become exercisable or, if
                  exercisable, cease to be exercisable by reason of either (I)
                  the occurrence of the Employee's Part-time Employment
                  Effective Date or (ii) the Employee's service during the
                  Employee's Part-time Employment Period being less than
                  full-time.

      6.    OTHER EMPLOYEE RIGHTS

            A.    PAID VACATION; HOLIDAYS. The Employee shall be entitled to not
                  less than four (4) weeks of annual vacation and all legal
                  holidays during which times his applicable compensation shall
                  be paid in full.

            B.    BUSINESS EXPENSES. The Employee is authorized to incur, and
                  will be entitled to receive prompt reimbursement for, all
                  reasonable expenses incurred by the Employee in performing his
                  duties and carrying out his responsibilities hereunder,
                  including business meal, entertainment and travel expenses,
                  provided that the Employee complies with the applicable
                  policies, practices and procedures of the Company relating to
                  the submission of expense reports, receipts or similar
                  documentation of those expenses. The Company shall either pay
                  directly or promptly reimburse the Employee for such expenses
                  not more than twenty (20) days after the submission to the
                  Company by the Employee from time to time of an itemized
                  accounting of such expenditures for which direct payment or
                  reimbursement is sought. Unpaid reimbursements after such
                  twenty (20) day period shall accrue interest in accordance
                  with Section 9(K).

            C.    SUPPORT. While on Active Status, the Employee shall be
                  provided by the Company with office space, furnishings, and
                  facilities, reserved parking, secretarial and administrative
                  assistance, supplies and other support equipment (including a
                  computer, facsimile machine and photocopier). .

      7.    COVENANT NOT TO COMPETE

            A.    The Employee recognizes that in each of the highly competitive
                  businesses in which the Company is engaged, personal contact
                  is of primary importance in securing new orthodontic practices
                  and in retaining the accounts and goodwill of present
                  practices and protecting the business of the Company. The
                  Employee, therefore, agrees that during the term of his
                  Employment and for a period of one (1) year after the
                  Termination Date, he will not, within fifty (50) miles of the
                  geographic location in which the he has devoted substantial
                  attention at such location to the material business interests
                  of the Company: (i) accept employment or render service to any
                  Person that is engaged in a business directly

                                       21
<PAGE>
                  competitive with the business then engaged in by the Company
                  or (ii) enter into or take part in or lend his name, counsel
                  or assistance to any business, either as proprietor,
                  principal, investor, partner, director, officer, employee,
                  consultant, advisor, agent, independent contractor, or in any
                  other capacity whatsoever, for any purpose that would be
                  competitive with the business of the Company.

            B.    If the provisions of this Section 7 are violated in any
                  material respect, the Company shall be entitled, upon
                  application to any court of proper jurisdiction, to a
                  temporary restraining order or preliminary injunction (without
                  the necessity of posting any bond with respect thereto) to
                  restrain and enjoin the Employee from that violation. If the
                  provisions of this Section 7 should ever be deemed to exceed
                  the time, geographic or occupational limitations permitted by
                  the applicable law, the Employee and the Company agree that
                  such provisions shall be and are hereby reformed to the
                  maximum time, geographic or occupational limitations permitted
                  by the applicable law.

      8.    CONFIDENTIAL INFORMATION

            A.    The Employee acknowledges that he has had and will continue to
                  have access to various Confidential Information. The Employee
                  agrees, therefore, that he will not at any time, either while
                  employed by the Company or afterwards, knowingly make any
                  independent use of, or knowingly disclose to any other person
                  (except as authorized by the Company) any Confidential
                  Information. Confidential Information shall not include (i)
                  information that becomes known to the public generally through
                  no fault of the Employee, (ii) information required to be
                  disclosed by law or legal process or the order of any
                  governmental authority under color of law, provided, that
                  prior to disclosing any information pursuant to this clause
                  (ii), the Employee shall, if possible, give prior written
                  notice thereof to the Company and provide the Company with the
                  opportunity to contest such disclosure, or (iii) the Employee
                  reasonably believes that such disclosure is required in
                  connection with the defense of a lawsuit against the Employee.
                  In the event of a breach or threatened breach by the Employee
                  of the provisions of this Section 8(A) with respect to any
                  Confidential Information, the Company shall be entitled to a
                  temporary restraining order and a preliminary and permanent
                  injunction (without the necessity of posting any bond in
                  connection therewith) restraining the Employee from
                  disclosing, in whole or in part, that Confidential
                  Information. Nothing herein shall be construed as prohibiting
                  the Company from pursuing any other available remedy for that
                  breach or threatened breach, including the recovery of
                  damages.

                                       22
<PAGE>
            B.    The Employee shall disclose promptly to the Company any and
                  all conceptions and ideas for inventions, improvements, and
                  valuable discoveries, whether patentable or not, which are
                  conceived or made by the Employee solely or jointly with any
                  other Person or Persons during the period of his Employment
                  and which pertain primarily to the material business
                  activities of the Company, and the Employee hereby assigns and
                  agrees to assign all his interests therein to the Company or
                  to its nominee; whenever requested to do so by the Company,
                  the Employee shall execute any and all applications,
                  assignments or other instruments which the Company shall deem
                  necessary to apply for and obtain Letters of Patent of the
                  United States or any foreign country or to otherwise protect
                  the Company's interest therein. These obligations shall (I)
                  continue beyond the Termination Date with respect to
                  inventions, improvements, and valuable discoveries, whether
                  patentable or not, conceived, made or acquired by the Employee
                  during the period of his Employment and (ii) be binding upon
                  the Employee's assigns, executors, administrators and other
                  legal representatives.

      9.    GENERAL PROVISIONS

            A.    SEVERABILITY. If any one or more of the provisions of this
                  Agreement shall, for any reason, be held or found by final
                  judgment of a court of competent jurisdiction to be invalid,
                  illegal or unenforceable in any respect, (i) such invalidity,
                  illegality or unenforceability shall not affect any other
                  provisions of this Agreement, (ii) this Agreement shall be
                  construed as if such invalid, illegal or unenforceable
                  provision had never been contained herein (except that this
                  clause (ii) shall not prohibit any modification allowed under
                  Section 7(B)), and (iii) if the effect of a holding or finding
                  that any such provision is invalid, illegal or unenforceable
                  is to modify to the Employee's detriment, reduce or eliminate
                  any compensation, reimbursement, payment, allowance or other
                  benefit to the Employee intended by the Company and Employee
                  in entering into this Agreement, the Company shall, within
                  thirty (30) days after the date of such finding or holding,
                  negotiate and expeditiously enter into an agreement with the
                  Employee which contains alternative provisions (reasonably
                  acceptable to the Employee) that will restore to the Employee
                  (to the extent lawfully permissible) substantially the same
                  economic, substantive and income tax benefits and legal rights
                  the Employee would have enjoyed had such provision been upheld
                  as legal, valid and enforceable.

            B.    NONEXCLUSIVITY OF RIGHTS. Nothing herein shall prevent or
                  limit the Employee's continuing or future participation in any
                  Compensation Plan or, subject to Section 9(N), limit or
                  otherwise affect such rights as the Employee may have under
                  any other contract or agreement with the

                                       23
<PAGE>
                  Company. Vested benefits and other amounts to which the
                  Employee is or becomes entitled to receive under any
                  Compensation Plan on or after the Termination Date shall be
                  payable in accordance with that Compensation Plan, except as
                  expressly modified hereby.

            C.    FULL SETTLEMENT. The Company's obligations to make the
                  payments provided for in, and otherwise to perform its
                  undertakings in, this Agreement shall not be affected by any
                  right of set-off, counterclaim, recoupment, defense or other
                  action, claim or right the Company may have against the
                  Employee or others. In no event shall the Employee be
                  obligated to seek other employment or take any other action by
                  way of mitigation of the amounts payable to the Employee under
                  any provision hereof, and those amounts shall not be reduced,
                  regardless of whether the Employee obtains other employment or
                  becomes self-employed.

            D.    SUCCESSORS.

                  (i) This Agreement is personal to the Employee and, without
                  the prior written consent of the Company, is not assignable by
                  the Employee otherwise than by will or the laws of descent and
                  distribution. This Agreement shall inure to the benefit and be
                  enforceable by the Employee's legal representatives acting in
                  their capacities as such pursuant to applicable law.

                  (ii) This Agreement shall inure to the benefit of and be
                  binding upon the Company and its successors and assigns. If
                  the Employee is not an Executive Officer, but is an officer of
                  a subsidiary of the Company, the Company shall be entitled to
                  assign all its obligations hereunder to that subsidiary and
                  treat the Employee as an employee of that subsidiary for all
                  purposes, but the Company shall remain liable for the full,
                  timely performance of all the obligations so assigned as if
                  the assignment had not been made.

                  (iii) The Company shall require any successor (direct or
                  indirect and whether by purchase, merger, consolidation, share
                  exchange or otherwise) to the business, properties and assets
                  of the Company substantially as an entirety expressly to
                  assume and agree to perform this Agreement in the same manner
                  and to the same extent the Company would have been required to
                  perform it had no such succession taken place.

            E.    AMENDMENTS; WAIVERS. This Agreement may not be amended or
                  modified except by a written agreement executed and delivered
                  by the parties hereto or their respective successors or legal
                  representatives acting in their capacities as such pursuant to
                  applicable law.

                  shall not be deemed a waiver of that provision or of any other
                  provision of or right under this Agreement.

            J.    HEADINGS. The headings of Sections and subsections hereof are
                  included solely for convenience of reference and shall not

                  of this Agreement.

            K.    INTEREST. If any amounts required to be paid or reimbursed to
                  the Employee hereunder are not so paid or reimbursed at the
                  times provided herein (including amounts required to be paid
                  by the Company pursuant to Sections 6 and 10, those amounts
                  shall accrue interest compounded daily at the annual
                  percentage rate which is three percentage points (3%) above
                  the interest rate announced by Texas Commerce Bank National
                  Association, Houston, Texas (or its successor), from time to

                  those amounts were required to have been paid or reimbursed to
                  the Employee until those amounts are finally and fully paid or
                  reimbursed; provided, however, that in no event shall the

                  allowed by applicable law.

            L.    PUBLICITY. The Company agrees with the Employee that, except
                  to the extent required by law or legal process (including the

                  publish, without the prior written consent of the Employee,
                  any written or oral statement concerning the terms of the
                  Employee's employment relationship with the Company and will
                  not, if a Notice of Termination is given by either the Company
                  or the Employee for any reason, publish or cause to be
                  published any statement concerning the Employee, including his
                  work-related performance or the reasons or basis for the
                  giving of that Notice of Termination.

            M.    TAX WITHHOLDING. Notwithstanding any other provision hereof,
                  the Company may withhold from amounts payable hereunder all
                  Federal, state, local and foreign taxes that are required to
                  be withheld by applicable laws or regulations.

                  that this Agreement supersedes all prior written and oral
                  agreements between them with respect to the employment of the
                  Employee by the Company.

<PAGE>
            A.    INTENDED BENEFITS; PAYMENT OF EXPENSES. In entering into this
                  Agreement the Company intends that the Employee receive
                  without reduction or delay all the intended benefits of this
                  Agreement and that those benefits, and the terms and
                  conditions hereof, be construed in a manner most favorable to
                  the Employee; the Company, therefore, agrees that it will
                  strive expeditiously and in good faith to construe and resolve
                  in the Employee's favor and to his benefit any ambiguities or
                  uncertainties that may be created by the express language
                  hereof. If, however, at any time during the term hereof or
                  afterwards: (i) there should exist a dispute or conflict
                  between the Employee and the Company or another Person as to
                  the validity, interpretation or application of any term or
                  condition hereof, or as to the Employee's entitlement to any
                  benefit intended to be bestowed hereby, which is not resolved
                  to the satisfaction of the Employee, (ii) the Employee must
                  (a) defend the validity of this Agreement, (b) contest any
                  determination by the Company concerning the amounts payable
                  (or reimbursable) by the Company to the Employee, or (c)
                  determine in any tax year of the Employee the tax consequences
                  to the Employee of any amounts payable (or reimbursable) under
                  Section 4(c) or 4(B)(iii), or (iii) the Employee must prepare
                  responses to an Internal Revenue Service ("IRS") audit of, or
                  otherwise defend, his personal income tax return for any year
                  the subject of any such audit, or an adverse determination,
                  administrative proceedings or civil litigation arising
                  therefrom that is occasioned by or related to an audit by the
                  IRS of the Company's income tax returns, then the Company
                  hereby unconditionally agrees: (a) on written demand of the
                  Company by the Employee, to provide sums sufficient to advance
                  and pay on a current basis (either by paying directly or by
                  reimbursing the Employee) not less than thirty (30) days after
                  a written request therefor is submitted by the Employee, the
                  Employee's out of pocket costs and expenses (including
                  attorney's fees, expenses of investigation, travel, lodging,
                  copying, delivery services and disbursements for the fees and
                  expenses of experts, etc.) incurred by the Employee in
                  connection with any such matter; (b) the Employee shall be
                  entitled, upon application to any court of competent
                  jurisdiction, to the entry of a mandatory injunction without
                  the necessity of posting any bond with respect thereto which
                  compels the Company to pay or advance such costs and expenses
                  on a current basis; and (c) the company's obligations under
                  this Section 10(A) will not be affected if the Employee is not
                  the prevailing party in the final resolution of any such
                  matter.

            B.    RESOLUTION OF DISPUTES. If a dispute of any type referred to
                  in Section 10(A) arises between the Company and the Employee
                  and they fail to resolve that dispute by direct negotiation,
                  the Company and the Employee agree that the next step taken to
                  resolve that dispute, prior to either party initiating any
                  litigation to resolve that dispute (not including any
                  litigation that may be required to enforce the Employee's
                  rights to the

                                       27
<PAGE>
                  payment or advancement of expenses and legal fees on a current
                  basis pursuant to Section 10(A)) shall be to submit the
                  dispute to an agreed Alternative Dispute Resolution ("ADR")
                  process, to which process the parties shall strive diligently
                  in good faith to agree within ten (10) business days after
                  either party has given written notice to the other party that
                  it is unable to concur in the other party's final proposed
                  negotiated resolution of the dispute. If the Company and the
                  Employee are unable to agree in writing to an acceptable ADR
                  process within that ten (10) business day period, then the
                  parties shall submit to a mandatory ADR process by making
                  joint application to the then Chief United States Federal
                  District Judge in the Southern District of Texas for the
                  selection of an ADR process for the parties. The parties shall
                  diligently in good faith participate in the ADR process chosen
                  by that judge. If the parties are unable to resolve their
                  dispute after diligent good faith participation in the ADR
                  process, then either party shall be free to initiate such
                  litigation as that party deems appropriate under the
                  circumstances. Under no circumstances shall the Employee be
                  obligated to pay for the cost of any ADR process or to pay or
                  reimburse the Company for any attorneys' fees, costs or other
                  expenses incurred by the Company in connection with any
                  process undertaken by the Employee to resolve disputes under
                  this Agreement. As used in this Section 10, the term
                  "Employee" includes, if the Employee has died or become
                  incompetent as a matter of applicable law, the Employee's
                  legal representative acting in his capacity as such under
                  applicable law.

      11.   INDEMNIFICATION

 The Employee shall be indemnified by the Company to the maximum extent
permitted by the law of Delaware, the state of the Company's incorporation, and
the law of the state of incorporation of any subsidiary of the Company of which
the Employee is a director or an officer or employee, as the same may be in
effect from time to time.

                             EMPLOYMENT AGREEMENT                   EXHIBIT 10.4

      THIS EMPLOYMENT AGREEMENT (this "Agreement"), is entered into on December
9, 1996, by and between APPLE ORTHODONTIX, INC., a Delaware corporation (the
"Company") and MICHAEL W. HARLAN (the "Employee").

                                    RECITALS:

      In entering into this Agreement, the Company desires to provide the
Employee with substantial incentives to serve the Company as a senior executive
performing at the highest levels of leadership and stewardship, without
distraction or concern over minimum compensation, benefits or tenure, to develop
and implement the Company's initial development plan and thereafter assist in
managing the Company's future growth and development and maximizing the returns
to the Company's stockholders. Further, the Employee understands and agrees that
prior to the Effective Date, he shall work on behalf of Apple as a full-time
consultant subject to certain completions or duties regarding his prior
employment with U. S. A. Waste Services, Inc.

      NOW, THEREFORE, in consideration of the foregoing and the mutual
provisions contained herein, and for other good and valuable consideration, the
parties hereto agree with each other as follows:

      1.    CERTAIN DEFINITIONS

            A.    CERTAIN DEFINITIONS. As used herein, the following terms have
                  the meanings assigned to them below:

                  "ACQUIRING PERSON" means any Person who or which, together
                  with all Affiliates and Associates of such Person, is or are
                  the Beneficial Owner of twenty-five percent (25%) or more of
                  the shares of Common Stock then outstanding, but does not
                  include any Exempt Person; provided, however, that a Person
                  shall not be or become an Acquiring Person if such Person,
                  together with its Affiliates and Associates, shall become the
                  Beneficial Owner of twenty-five percent (25%) or more of the
                  shares of Common Stock then outstanding solely as a result of
                  a reduction in the number of shares of Common Stock
                  outstanding due to the repurchase of Common Stock by the
                  Company, unless and until such time as such Person or any
                  Affiliate or Associate of such Person shall purchase or
                  otherwise become the Beneficial Owner of additional shares of
                  Common Stock constituting one percent (1%) or more of the then
                  outstanding shares of Common Stock or any other Person (or
                  Persons) who is (or collectively are) the Beneficial Owner of
                  shares of Common Stock constituting one percent (1%) or more
                  of the then outstanding shares of Common Stock shall become an
                  Affiliate or Associate of such Person,
<PAGE>
                  unless, in either such case, such Person, together with all
                  Affiliates and Associates of such Person, is not then the
                  Beneficial Owner of twenty-five percent (25%) or more of the
                  shares of Common Stock then outstanding.

                  "ACTIVE STATUS" means the Employee's Employment status from

                  the Part-time Employment Effective Date or (b) the Termination
                  Date.

                  amounts deferred at the election of the Employee pursuant to a
                  Compensation Plan intended to qualify as a plan under Section
                  401(k) of the Code or otherwise. If salary or bonus is paid in
                  whole or in part in property other than cash (such as Common
                  Stock) the amount so paid shall be the fair market value
                  thereof on the date of payment.

                  "ASSOCIATE" means, with reference to any Person, (a) any
                  corporation, firm, partnership, association, unincorporated
                  organization or other entity (other than the Company or a
                  subsidiary of the Company) of which that Person is an officer
                  or general partner (or officer or general partner of a general
                  partner) or is, directly or indirectly, the Beneficial Owner
                  of 10% or more of any class of its equity securities, (b) any
                  trust or other estate in which that Person has a substantial
                  beneficial interest or for or of which that Person serves as
                  trustee or in a similar fiduciary capacity and (c) any
                  relative or spouse of that Person, or any relative of that
                  spouse, who has the same home as that Person.

                  "AVERAGE ANNUAL CASH COMPENSATION" of the Employee
                  means, as of the Part-time Employment Effective Date, the
                  average of (a) the Annual Cash Compensation earned by the
                  Employee in each of the two (2) Compensation Years next
                  preceding that date or, if less than two (2) Compensation
                  Years have occurred prior to that date and since the Effective
                  Date, (b) the Annual Cash Compensation in each whole
                  Compensation Year, if any, and, restated on an annualized
                  basis, the Annual Cash Compensation in each partial
                  Compensation Year (up to a maximum of two (2) partial
                  Compensation Years) next preceding the Part-time Employment
                  Effective Date.

                  "BASE SALARY" means: (a) prior to the Part-time Employment
                  Effective Date, the guaranteed minimum annual salary payable
                  by the Company to the Employee pursuant to Section 4(A); and
                  (b) on and after

                  minimum annual salary payable by the Company to the Employee
                  pursuant to Section 5(E).

                  A specified Person is deemed the "BENEFICIAL OWNER" of, and is
                  deemed to "beneficially own," any securities:

                        (a) of which that Person or any of that Person's
                  Affiliates or Associates, directly or indirectly, is the
                  "beneficial owner" (as determined pursuant to Exchange Act
                  Rule 13d-3) or otherwise has the right to vote or dispose of,
                  including pursuant to any agreement, arrangement or
                  understanding (whether or not in writing); provided, however,
                  that a Person shall not be deemed the "Beneficial Owner" of,
                  or to "beneficially own," any security under this subparagraph
                  (a) as a result of an agreement, arrangement or understanding
                  to vote that security if that agreement, arrangement or
                  understanding: (1) arises solely from a revocable proxy or
                  consent given in response to a public (that is, not including
                  a solicitation exempted by Exchange Act Rule 14a-2(b)(2))
                  proxy or consent solicitation made pursuant to, and in
                  accordance with, the applicable provisions of the Exchange
                  Act; and (2) is not then reportable by such Person on Exchange
                  Act Schedule 13D (or any comparable or successor report);

                        (b) which that Person or any of that Person's Affiliates
                  or Associates, directly or indirectly, has the right or
                  obligation to acquire (whether that right or obligation is
                  exercisable or effective immediately or only after the passage
                  of time or the occurrence of an event) pursuant to any
                  agreement, arrangement or understanding (whether or not in
                  writing) or on the exercise of conversion rights, exchange
                  rights, other rights, warrants or options, or otherwise;
                  provided, however, that a Person shall not be deemed the
                  "Beneficial Owner" of, or to "beneficially own," securities
                  tendered pursuant to a tender or exchange offer made by that
                  Person or any of that Person's Affiliates or Associates until
                  those tendered securities are accepted for purchase or
                  exchange; or

                        (c) which are beneficially owned, directly or
                  indirectly, by (1) any other Person (or any Affiliate or
                  Associate thereof) with which the specified Person or any of
                  the specified Person's Affiliates or Associates has any
                  agreement, arrangement or understanding (whether or not in
                  writing) for the purpose of acquiring, holding, voting (except
                  pursuant to a revocable proxy or consent as described in the
                  proviso to subparagraph (a) of this definition) or disposing
                  of any voting securities of the Company or (2) any group (as
                  that term is used in Exchange Act Rule 13d-5(b)) of which that
                  specified Person is a member; provided, however, that nothing
                  in this definition shall cause a Person engaged in business as
                  an underwriter of securities to be the "Beneficial Owner" of,
                  or to

                                      3
<PAGE>
                  "beneficially own," any securities acquired through such
                  Person's participation in good faith in a firm commitment
                  underwriting until the expiration of forty (40) days after the
                  date of that acquisition. For purposes of this Agreement,
                  "voting" a security shall include voting, granting a proxy,
                  acting by consent, making a request or demand relating to
                  corporate action (including, without limitation, calling a
                  stockholder meeting) or otherwise giving an authorization
                  (within the meaning of Section 14(a) of the Exchange Act) in
                  respect of such security. "BOARD" means the entire Board of
                  Directors of the Company.

                  "BUSINESS REASON" for the Company's termination of the
                  Employee's Employment means any lawful reason other than
                  Cause.

                  "CAUSE" for the Company's termination of the Employee's
                  Employment means: (a) the Employee's final conviction of a
                  felony crime that enriched the Employee at the expense of the
                  Company; or (b) the Employee's deliberate and intentional
                  continuing failure to substantially perform his duties and
                  responsibilities hereunder (except by reason of the Employee's
                  incapacity due to physical or mental illness or injury) for a
                  period of forty-five (45) days after the Required Board
                  Majority has delivered to the Employee a written demand for
                  substantial performance hereunder which specifically
                  identifies the bases for the Required Board Majority's
                  determination that the Employee has not substantially
                  performed his duties and responsibilities hereunder (such
                  period being the "Grace Period"); provided, that for purposes
                  of this clause (b), the Company shall not have Cause to
                  terminate the Employee's Employment unless (1) at a meeting of
                  the Board called and held following the Grace Period in the
                  city in which the Company's principal executive offices are
                  located of which the Employee was given not less than ten (10)
                  days' prior written notice and at which the Employee was
                  afforded the opportunity to be represented by counsel, appear
                  and be heard, the Required Board Majority shall adopt a
                  written resolution which (A) sets forth the Required Board
                  Majority's determination that the failure of the Employee to
                  substantially perform his duties and responsibilities
                  hereunder has (except by reason of his incapacity due to
                  physical or mental illness or injury) continued past the Grace
                  Period and (B) specifically identifies the bases for that
                  determination and (2) the Company, at the written direction of

      2.    EMPLOYMENT

         A.       On the terms and subject to the conditions hereinafter set
                  forth, and beginning as of the Effective Date, the Company
                  will employ the Employee as its Chief Financial Officer (CFO)
                  and Vice-President the Employee will serve in the Company's
                  employ in that position. The Employee shall perform such
                  duties, and have such powers, authority, functions, duties and
                  responsibilities for the Company and corporations affiliated
                  with the Company as are commensurate and consistent with his
                  employment as the Company's Chief Financial Officer and
                  Vice-President. The Employee also shall have such additional
                  powers, authority, functions, duties and responsibilities as
                  may be assigned to him by the Board; provided that, without
                  the Employee's written consent, such

                                      11
<PAGE>
                  additional powers, authority, functions, duties and
                  responsibilities shall not be inconsistent or interfere with,
                  or detract from, those herein vested in, or otherwise then
                  being performed for the Company by the Employee.

         B.       The Employee shall not, at any time during his Employment,
                  engage in any other activities unless those activities do not
                  interfere materially with the Employee's duties and
                  responsibilities for the Company at that time, except that the
                  Employee shall be entitled, subject to the provisions of
                  Section 7, (a) to continue with such activities as the
                  Employee has carried on prior to the Effective Date, including
                  making and managing his personal investments and participating
                  in other business or civic activities and (b) to serve on
                  corporate or other business, civic or charitable boards or
                  committees and trade association or similar boards or
                  committees.

      3. TERM OF EMPLOYMENT. Subject to the provisions of Section 5, the term of
the Employee's Employment shall be for a continually renewing term of three (3)
years commencing on the Effective Date and renewing each day thereafter for an
additional day without any further action by either the Company or the Employee,
it being the intention of the parties that there shall be continuously a
remaining term of three (3) years' duration of the Employee's Employment until
an event has occurred as described in, or one of the parties shall have made an
appropriate election pursuant to, the provisions of Section 5. When the
Termination Date shall have occurred and the Company shall have paid to the
Employee all the applicable amounts Section 5 provides the Company shall pay as
a result of the termination of the Employee's Employment, including all amounts
accruing during the Part-time Employment Period, if any, this Agreement will
terminate and have no further force or effect, except that Sections 4(C), 8, 9,
10 and 11 shall survive that termination indefinitely and Section 7 shall
survive for the period of time provided for therein.

      4.    COMPENSATION

         A.       BASE SALARY. A Base Salary shall be payable to the Employee by
                  the Company as a guaranteed minimum annual amount hereunder
                  for each Compensation Year during the period from the
                  Effective Date to the first to occur of the Part-time
                  Employment Effective Date or the Termination Date. That Base
                  Salary shall be payable in the intervals consistent with the
                  Company's normal payroll schedules (but in no event less
                  infrequently than semi-monthly), shall be payable initially at
                  the annual rate of $130,000 and shall be increased (but not
                  decreased or adjusted other than as provided in Section 5) as
                  follows:

                  (i) on the first and each subsequent anniversary of the
                  Effective Date, by the same percentage increase (if any) in
                  the CPI for the twelve (12) month period immediately preceding
                  such anniversary;

                                      12
<PAGE>
                  (ii) on the first and each subsequent anniversary of the
                  Effective Date, by such additional amount as shall be
                  determined in the sole discretion of the Compensation
                  Committee, but only in such form and to such extent as the
                  Compensation Committee may from time to time approve, as
                  evidenced by the written minutes or records of the
                  Compensation Committee and its written notices of such
                  determinations or approvals to the Employee; and

                  (iii) if the Employee relocates from a state without a
                  personal income tax at the time of his relocation to a state
                  having a personal income tax, or if the Employee resides in a
                  state without a personal income tax on the date hereof which
                  subsequently adopts a personal income tax, then, in either
                  case, the Base Salary in effect at the time of such relocation
                  or adoption, as applicable, shall immediately be increased by
                  the amount equal to the Base Salary immediately prior to this
                  increase multiplied by seventy percent (70%) of the highest
                  personal income tax rate of such state; for example, if the
                  Employee relocates from a state without a personal income tax
                  to a state having a personal income tax and the highest rate
                  of that tax is six percent (6%) when the Base Salary is
                  $200,000, then the Base Salary will be increased by $8,400
                  (computed at 70% x 6% x $200,000); provided, however, that the
                  obligation of the Company to pay the Base Salary earned by the
                  Employee for his service in the period beginning on the
                  Effective Date and ending on the date that is the first to
                  occur of (a) the IPO Closing Date, (b) the Termination Date or
                  (C) such other date as the Board in its sole discretion may
                  determine shall be deferred to the last day of that period in
                  such amounts as the Board in its sole discretion may from time
                  to time determine, on which day the Company shall pay in full
                  to the Employee, without interest, the aggregate earned but
                  unpaid amount of the Base Salary for that period. Effective as
                  of the Part-time Employment Effective Date, the Base Salary
                  theretofore in effect shall be adjusted as provided in Section
                  5(E).

            B.    OTHER COMPENSATION.

                  (i) The Employee shall be entitled to participate in all
                  Compensation Plans from time to time in effect while he
                  remains on Active Status, regardless of whether the Employee
                  is an Executive Officer. All awards to the Employee under all
                  Incentive Plans shall take into account the Employee's
                  positions with and duties and responsibilities to the Company
                  and its subsidiaries.

                                      13
<PAGE>
                  (ii) The Company shall grant to the Employee 23.5 shares of
                  it's pre- IPO common stock subject to a subscription
                  agreement.

         C.       TAX INDEMNITY. Should any of the payments of Base Salary,
                  other incentive or supplemental compensation, benefits,
                  allowances, awards, payments, reimbursements or other
                  perquisites, or any other payment in the nature of
                  compensation, singly, in any combination or in the aggregate,
                  that are provided for hereunder to be paid to or for the
                  benefit of the Employee be determined or alleged to be subject
                  to an excise or similar purpose tax pursuant to Section 4999
                  of the Code, or any successor or other comparable federal,
                  state or local tax law by reason of being a "parachute
                  payment" (within the meaning of Section 280G of the Code), the
                  Company shall pay to the Employee such additional compensation
                  as is necessary (after taking into account all federal, state
                  and local taxes payable by the Employee as a result of the
                  receipt of such additional compensation) to place the Employee
                  in the same after-tax position (including federal, state and
                  local taxes) he would have been in had no such excise or
                  similar purpose tax (or interest or penalties thereon) been
                  paid or incurred. The Company hereby agrees to pay such
                  additional compensation within the earlier to occur of (i)
                  five (5) business days after the Employee notifies the Company
                  that the Employee intends to file a tax return taking the
                  position that such excise or similar purpose tax is due and
                  payable in reliance on a written opinion of the Employee's tax
                  counsel (such tax counsel to be chosen solely by the Employee)
                  that it is more likely than not that such excise tax is due
                  and payable or (ii) twenty-four (24) hours of any notice of or
                  action by the Company that it intends to take the position
                  that such excise tax is due and payable. The costs of
                  obtaining the tax counsel opinion referred to in clause (i) of
                  the preceding sentence shall be borne by the Company, and as
                  long as such tax counsel was chosen by the Employee in good
                  faith, the conclusions reached in such opinion shall not be
                  challenged or disputed by the Company. If the Employee intends
                  to make any payment with respect to any such excise or similar
                  purpose tax as a result of an adjustment to the Employee's tax
                  liability by any federal, state or local tax authority, the
                  Company will pay such additional compensation by delivering
                  its cashier's check payable in such amount to the Employee
                  within five (5) business days after the Employee notifies the
                  Company of his intention to make such payment. Without
                  limiting the obligation of the Company hereunder, the Employee
                  agrees, in the event the Employee makes any payment pursuant
                  to the preceding sentence, to negotiate with the Company in
                  good faith with respect to procedures reasonably requested by
                  the Company which would afford the Company the ability to
                  contest the imposition of such excise or similar purpose tax;
                  provided, however, that the Employee will not be required to
                  afford the Company any right to contest the applicability of
                  any such excise or similar purpose tax to the extent that the
                  Employee

                                      14
<PAGE>
                  reasonably determines (based upon the opinion of his tax
                  counsel) that such contest is inconsistent with the overall
                  tax interests of the Employee.

      5.    TERMINATION, PART-TIME EMPLOYMENT PERIOD, DISABILITY AND
            DEATH

            A.    TERMINATION OF EMPLOYMENT BY THE COMPANY.

                  (i) The Company shall be entitled, if acting at the direction
                  of the Required Board Majority, to terminate the Employee's
                  Employment (a) at any time for Type I Cause or (b) at any time
                  prior to the Part-time Employment Effective Date for Type II
                  Cause or for any Business Reason. If the Employee is neither a
                  member of the Board nor an Executive Officer, the Company
                  shall be entitled, if acting at the direction of the chief
                  executive officer of the Company, to terminate the Employee's
                  Employment at any time prior to the Part-time Employment Date
                  for any Business Reason. The Company's termination of the
                  Employee's Employment for Cause will be effective on the date
                  the Company delivers a Notice of Termination for Cause to the
                  Employee pursuant to this Section 5(A)(i)(together, in the
                  case of a termination for Type II Cause, with the certified
                  resolution referred to in clause (b) of the definition herein
                  of Cause), while the Company's termination of the Employee's
                  Employment for a Business Reason will be effective on the
                  third (3rd) anniversary of the date the Company delivers a
                  Notice of Termination for a Business Reason to the Employee
                  pursuant to this Section 5(A)(i).

                  (ii) If the Company terminates the Employee's Employment for
                  Cause, the Company promptly thereafter, and in any event
                  within five (5) business days thereafter, shall pay the
                  Employee his Base Salary to and including the Termination Date
                  and the amount of all compensation previously deferred by the
                  Employee (together with any accrued interest or earnings
                  thereon), in each case to the extent not theretofore paid,
                  and, when that payment is made, the Company shall,
                  notwithstanding Section 3, have no further or other
                  obligations hereunder to the Employee.

                  (iii) If the Company terminates the Employee's Employment for
                  a Business Reason, the respective rights and obligations of
                  the Company and the Employee during the Part-time Employment
                  Period will be as set forth in Section 5(E).

            B.    TERMINATION OF EMPLOYMENT BY THE EMPLOYEE.

                  (i) The Employee shall be entitled to terminate his Employment
                  (a) for a Good Reason at any time within one hundred eighty
                  (180) days after the

                                      15
<PAGE>
                  facts or circumstances constituting that Good Reason first
                  exist and are known to the Employee, (b) by reason of a Change
                  of Control at any time within three hundred sixty-five (365)
                  days after that Change of Control occurs (provided, however,
                  that the Employee shall not be entitled to terminate his
                  Employment by reason of that Change of Control if it occurs
                  (1) during the thirty (30) day period following the Company's
                  receipt of the Employee's Notice of Termination without Good
                  Reason and other than for Disability pursuant to this Section
                  5(B)(i), (2) after (A) the receipt by the Nonterminating Party
                  of the Terminating Party's Notice of Termination pursuant to
                  Section 5 (c) or (B) the Employee's receipt of the Company's
                  Notice of Termination for a Business Reason (other than in
                  connection with that Change of Control) pursuant to Section
                  5(A) or (3) more than three hundred sixty-five (365) days
                  after the Company's receipt of the Employee's Notice of
                  Termination for Good Reason pursuant to this Section 5(B)(i))
                  or (c) without Good Reason and other than for Disability at
                  any time. The Employee's termination of his Employment for
                  Good Reason will be effective on the third (3rd) anniversary
                  of the date the Employee delivers a Notice of Termination for
                  Good Reason to the Company pursuant to this Section 5(B)(i).
                  The Employee's termination of his Employment by reason of a
                  Change of Control will be effective on the first date on which
                  the Change of Control Payment shall have been paid in full to
                  the Employee. The Employee's termination of his Employment
                  without Good Reason and other than for Disability will be
                  effective on the thirtieth (30th) day following the Employee's
                  delivery of a Notice of Termination without Good Reason and
                  other than for Disability pursuant to this Section 5(B)(i).

                  (ii) If the Employee terminates his Employment for Good
                  Reason, the respective rights and obligations of the Company
                  and the Employee during the Part-time Employment Period will
                  be as set forth in Section 5(E).

                  (iii) If the Employee terminates his Employment by reason of a
                  Change of Control, the Company shall pay to the Employee in a
                  cash lump sum within five (5) business days after the date the
                  Company receives the Employee's Notice of Termination by
                  reason of that Change of Control the amount equal to the sum
                  of (a) the portion of the Base Salary to and including the
                  Termination Date which has not yet been paid, (b) all
                  compensation previously deferred by the Employee (together
                  with any accrued interest and earnings thereon), (c) any
                  accrued but unpaid vacation pay and (d) the Change of Control
                  Payment.

                  (iv) If the Employee terminates his Employment without Good
                  Reason and other than for Disability, the Company shall pay to
                  the Employee, in a cash lump sum within five (5) business days
                  after the Termination Date, the amount equal to the sum of (a)
                  the portion of the Base Salary to and

                                      16
<PAGE>
                  including the Termination Date which has not yet been paid,
                  (b) all compensation previously deferred by the Employee
                  (together with any accrued interest and earnings thereon)
                  which has not yet been paid, (c) any accrued but unpaid
                  vacation pay and (d) the amount equal to fifty percent (50%)
                  of the Base Salary being paid for the Compensation Year in
                  which the Company receives the Employee's Notice of
                  Termination without Good Reason and other than for Disability;
                  provided, however, that if the Employee terminates his
                  Employment without Good Reason and other than for Disability
                  within six (6) months of the theretofore scheduled final day
                  of the Part-time Employment Period, the amount payable
                  pursuant to clause (d) of this sentence shall be the amount
                  determined pursuant to that clause multiplied by a fraction
                  the numerator of which is the number of days from and
                  excluding the date the Company receives the Notice of
                  Termination to and including that final day and the
                  denominator of which is one hundred eighty-two (182). For
                  purposes of this Section 5(B)(iv), if the anniversary of the
                  Effective Date in the Compensation Year in which the Company
                  receives the Notice of Termination without Good Reason and
                  other than for Disability has not occurred on or prior to the
                  date of that receipt, the Base Salary for that Compensation
                  Year will be calculated on the assumption that no increase in
                  the amount thereof would be made effective as of that
                  anniversary pursuant to Section 4(A) or 5(E)(i), as
                  applicable.

         C.       TERMINATION BY REASON OF DISABILITY. If the Employee incurs
                  any Disability while on Active Status, either the Employee or
                  the Company may terminate the Employee's Employment effective
                  on the third (3rd) anniversary of the date the Nonterminating
                  Party receives a Notice of Termination from the Terminating
                  Party pursuant to this Section 5(C). If the Employee's
                  Employment is terminated by reason of the Employee's
                  Disability, the respective rights and obligations of the
                  Company and the Employee during the Part-time Employment
                  Period will be as set forth in Section 5(E).

         D.       TERMINATION OF EMPLOYMENT BY DEATH. The Employee's Employment
                  shall terminate automatically at the time of his death. If the
                  Employee's Employment is terminated by reason of the
                  Employee's death, the Company shall pay to the Person the
                  Employee has designated in a written notice delivered to the
                  Company as his beneficiary entitled to such payment, if any,
                  or to the Employee's estate, as applicable, in a cash lump sum
                  within thirty (30) days after the Termination Date, the amount
                  equal to the sum of (i) the portion of the Base Salary through
                  the end of the month in which the Termination Date occurs
                  which has not yet been paid, (ii) all compensation previously
                  deferred by the Employee (together with any accrued interest
                  or earnings thereon) which has not yet been paid, (iii) any
                  accrued but unpaid vacation pay (if the Employee dies while

                                      17
<PAGE>
                  on Active Status) and (iv) (a) if the Employee dies while on
                  Active Status, the product of (1) the Base Salary being paid
                  for the Compensation Year in which he dies multiplied by (2)
                  three (3) or (b) if the Employee dies during the Part-time
                  Employment Period, the product of (1) one-twelfth (1/12th) of
                  the Base Salary being paid for the Compensation Year in which
                  the Employee dies multiplied by (2) the number of whole and
                  partial calendar months in the period beginning with the first
                  calendar month after the calendar month in which he dies and
                  ending with the last calendar month in which the Termination
                  Date would have occurred if the Employee's Employment were to
                  have continued to the end of the Part-time Employment Period.
                  For purposes of this Section 5(D), if the anniversary of the
                  Effective Date in the Compensation Year in which the Employee
                  dies has not occurred on or before the Termination Date, the
                  Base Salary for that Compensation Year will be calculated on
                  the assumption that no increase in the amount thereof would be
                  made effective as of that anniversary pursuant to Section 4(A)
                  or 5(E)(i), as applicable.

            E.    EMPLOYEE'S RIGHTS DURING THE PART-TIME EMPLOYMENT
                  PERIOD.

                  (i) The Company shall pay the Employee a Base Salary, in the
                  intervals consistent with the Company's normal payroll
                  schedules (but in no event less frequently than semi-monthly)
                  from the Part-time Employment Effective Date to and including
                  the Termination Date in the amounts determined from time to
                  time as follows: Effective as of the Part-time Employment
                  Effective Date, the Base Salary payable by the Company to the
                  Employee for the period from and including that date to and
                  excluding the third (3rd) anniversary of that date shall be as
                  follows:

                        (a) if the Part-time Employment Effective Date occurs as
                        a result of the receipt by the Nonterminating Party of a
                        Notice of Termination for a Business Reason pursuant to
                        Section 5(A) or a Notice of Termination for Good Reason
                        pursuant to Section 5(B)(i), the amount equal to the
                        Average Annual Cash Compensation of the Employee
                        determined as of the Part-time Employment Effective
                        Date; and (b) if the Part-time Employment Effective Date
                        occurs as a result of the receipt by the Nonterminating
                        Party of a Notice of Termination for Disability pursuant
                        to Section 5(C), the amount equal to the amount by which
                        (1) seventy-five percent (75%) of the Average Annual
                        Cash Compensation of the Employee determined as of the
                        Part-time Employment Effective Date exceeds (2) the
                        aggregate amount of periodic payments the Employee
                        receives during the twelve (12) months beginning on that
                        date under Compensation Plans then in

                                      18
<PAGE>
                        effect and providing for the payment to the Employee
                        solely as a result or on account of disability; and

                        (b) on the first and each subsequent anniversary of the
                        Part-time Employment Effective Date, the Base Salary
                        payable pursuant to this Section 5(E) shall be increased
                        (but not decreased) by the same percentage increase (if
                        any) in the CPI for the twelve (12) month period
                        immediately preceding that anniversary.

                (ii)    (a) The Employee shall continue to participate in all
                        Compensation Plans from time to time in effect during
                        the Part-time Employment Period, provided, however,
                        that: (1) the Employee shall not be entitled to receive
                        any new award or grant under any Incentive Plan, and any
                        such new award or grant shall be at the sole discretion
                        of the Compensation Committee or the Board, as
                        applicable, with respect to that Incentive Plan; and (2)
                        if (A) the terms of any such plan preclude the
                        Employee's continued participation therein or (B) his
                        continued participation in any such plan would or
                        reasonably could be expected to disqualify that plan
                        under the Code, the Employee shall not be entitled to
                        participate in that plan, but the Company instead shall
                        provide the Employee with the after-tax equivalent of
                        the benefits that would have been provided to the
                        Employee were he a participant in that plan.

                        (b) For purposes of determining eligibility (including
                        years of service) for retirement benefits payable under
                        any Compensation Plan, the Employee shall be deemed to
                        have retired at the Termination Date.

                  (iii) Subject to the provisions of Section 7, the Employee
                  shall not be (A) prevented from accepting other employment or
                  engaging in (and devoting substantially all his time to) other
                  business activities or (B) required to perform any regular
                  duties for the Company (except to provide such services
                  consistent with the Employee's educational background,
                  experience and prior positions with the Company as may be
                  acceptable to the Employee) or to seek or accept additional
                  employment with any other Person. If the Employee, at his
                  discretion, shall accept any such additional employment or
                  engage in any such other business activity there shall be no
                  offset, reduction or effect upon any rights, benefits or
                  payments to which the Employee is entitled pursuant to this
                  Agreement. Furthermore, the Employee shall have no obligation
                  to account for, remit, rebate or pay over to the Company any
                  compensation or other amounts earned or derived in connection
                  with such additional employment or business activity.

                        The Employee shall, however, make himself generally
                  available for special projects or to consult with the Company
                  and its employees at such times and at such places as may be
                  reasonably requested by the Company and which shall be
                  reasonably satisfactory to the Employee and consistent with
                  the Employee's regular duties and responsibilities in the
                  course of his then new occupation or other employment, if any.

                  (iv) Unless and until the Employee shall have sustained a
                  Disability, the Company shall continue to provide the Employee
                  with either the same or, at the Company's election, at a
                  different location within thirty-five (35) miles of the
                  Employee's principal residence, in any case reasonably
                  acceptable to the Employee, alternate but comparable office
                  space, furnishings, facilities, reserved parking, supplies,
                  services, equipment, secretarial and administrative assistance
                  that are in each case at least commensurate with the size and
                  quality of that which were provided to the Employee during the
                  Compensation Year immediately preceding the Part-time
                  Employment Effective Date pursuant to Section 6(C), but in no
                  event less than are being furnished or provided on the date
                  hereof. The Company and Employee may mutually agree upon an
                  equivalent monthly cash allowance in lieu of the Employee
                  being provided all or any part of these items.

                  (v) The Employee shall remain entitled to the benefits of
                  Section 4(C).

         F.       RETURN OF PROPERTY. On termination of the Employee's
                  Employment, however brought about, the Employee (or his
                  representatives) shall promptly deliver and return to the
                  Company all the Company's property that is in the possession
                  or under the control of the Employee.

         G.       STOCK OPTIONS. Notwithstanding any provision of this Agreement
                  to the contrary: (i) except in the case of a termination of
                  the Employee's Employment for Cause, all stock options
                  previously granted to the Employee under Incentive Plans that
                  have not been exercised and are outstanding as of the time
                  immediately prior to the Termination Date shall,
                  notwithstanding any contrary provision of any applicable
                  Incentive Plan, remain outstanding (and continue to become
                  exercisable pursuant to their respective terms) until
                  exercised or the expiration of their term, whichever is
                  earlier; and (ii) in the case of a termination of the
                  Employee's Employment for Cause, all stock options previously
                  granted to the Employee under Incentive Plans that have not
                  been exercised and are outstanding as of the time immediately
                  prior to the Termination Date shall, notwithstanding any
                  contrary provision of any applicable Incentive Plan, remain
                  outstanding and continue to be exercisable until exercised or
                  the date that is ten (10) days after the Termination Date,
                  whichever is

                                      20
<PAGE>
                  earlier. No stock option previously granted to the Employee
                  under any Incentive Plan shall, notwithstanding any contrary
                  provision of that Incentive Plan, expire or fail to become
                  exercisable or, if exercisable, cease to be exercisable by
                  reason of either (i) the occurrence of the Employee's
                  Part-time Employment Effective Date or (ii) the Employee's
                  service during the Employee's Part-time Employment Period
                  being less than full-time.

      6.    OTHER EMPLOYEE RIGHTS

      ***   A.    PAID VACATION; HOLIDAYS. The Employee shall be entitled to not
                  less than four (4) weeks of annual vacation and all legal
                  holidays during which times his applicable compensation shall
                  be paid in full.

            B.    BUSINESS EXPENSES. The Employee is authorized to incur, and
                  will be entitled to receive prompt reimbursement for, all
                  reasonable expenses incurred by the Employee in performing his
                  duties and carrying out his responsibilities hereunder,
                  including business meal, entertainment and travel expenses,
                  provided that the Employee complies with the applicable
                  policies, practices and procedures of the Company relating to
                  the submission of expense reports, receipts or similar
                  documentation of those expenses. The Company shall either pay
                  directly or promptly reimburse the Employee for such expenses
                  not more than twenty (20) days after the submission to the
                  Company by the Employee from time to time of an itemized
                  accounting of such expenditures for which direct payment or
                  reimbursement is sought. Unpaid reimbursements after such
                  twenty (20) day period shall accrue interest in accordance
                  with Section 9(K).

            C.    SUPPORT. While on Active Status, the Employee shall be
                  provided by the Company with office space, furnishings, and
                  facilities, reserved parking, secretarial and administrative
                  assistance, supplies and other support equipment (including a
                  computer, facsimile machine and photocopier). .

      7.    COVENANT NOT TO COMPETE

            A.    The Employee recognizes that in each of the highly competitive
                  businesses in which the Company is engaged, personal contact
                  is of primary importance in securing new orthodontic practices
                  and in retaining the accounts and goodwill of present
                  practices and protecting the business of the Company. The
                  Employee, therefore, agrees that during the term of his
                  Employment and for a period of one (1) year after the
                  Termination Date, he will not, within fifty (50) miles of the
                  geographic location in which the he has devoted substantial
                  attention at such location to the

                                      21
<PAGE>
                  material business interests of the Company: (i) accept
                  employment or render service to any Person that is engaged in
                  a business directly competitive with the business then engaged
                  in by the Company or (ii) enter into or take part in or lend
                  his name, counsel or assistance to any business, either as
                  proprietor, principal, investor, partner, director, officer,
                  employee, consultant, advisor, agent, independent contractor,
                  or in any other capacity whatsoever, for any purpose that
                  would be competitive with the business of the Company.

            B.    If the provisions of this Section 7 are violated in any
                  material respect, the Company shall be entitled, upon
                  application to any court of proper jurisdiction, to a
                  temporary restraining order or preliminary injunction (without
                  the necessity of posting any bond with respect thereto) to
                  restrain and enjoin the Employee from that violation. If the
                  provisions of this Section 7 should ever be deemed to exceed
                  the time, geographic or occupational limitations permitted by
                  the applicable law, the Employee and the Company agree that
                  such provisions shall be and are hereby reformed to the
                  maximum time, geographic or occupational limitations permitted
                  by the applicable law.

      8.    CONFIDENTIAL INFORMATION

            A.    The Employee acknowledges that he has had and will continue to
                  have access to various Confidential Information. The Employee
                  agrees, therefore, that he will not at any time, either while
                  employed by the Company or afterwards, knowingly make any
                  independent use of, or knowingly disclose to any other person
                  (except as authorized by the Company) any Confidential
                  Information. Confidential Information shall not include (i)
                  information that becomes known to the public generally through
                  no fault of the Employee, (ii) information required to be
                  disclosed by law or legal process or the order of any
                  governmental authority under color of law, provided, that
                  prior to disclosing any information pursuant to this clause
                  (ii), the Employee shall, if possible, give prior written
                  notice thereof to the Company and provide the Company with the
                  opportunity to contest such disclosure, or (iii) the Employee
                  reasonably believes that such disclosure is required in
                  connection with the defense of a lawsuit against the Employee.
                  In the event of a breach or threatened breach by the Employee
                  of the provisions of this Section 8(A) with respect to any
                  Confidential Information, the Company shall be entitled to a
                  temporary restraining order and a preliminary and permanent
                  injunction (without the necessity of posting any bond in
                  connection therewith) restraining the Employee from
                  disclosing, in whole or in part, that Confidential
                  Information. Nothing herein shall be construed as prohibiting
                  the Company from pursuing any other available remedy for that
                  breach or threatened breach, including the recovery of
                  damages.

                                       22
<PAGE>
            B.    The Employee shall disclose promptly to the Company any and
                  all conceptions and ideas for inventions, improvements, and
                  valuable discoveries, whether patentable or not, which are
                  conceived or made by the Employee solely or jointly with any
                  other Person or Persons during the period of his Employment
                  and which pertain primarily to the material business
                  activities of the Company, and the Employee hereby assigns and
                  agrees to assign all his interests therein to the Company or
                  to its nominee; whenever requested to do so by the Company,
                  the Employee shall execute any and all applications,
                  assignments or other instruments which the Company shall deem
                  necessary to apply for and obtain Letters of Patent of the
                  United States or any foreign country or to otherwise protect
                  the Company's interest therein. These obligations shall (i)
                  continue beyond the Termination Date with respect to
                  inventions, improvements, and valuable discoveries, whether
                  patentable or not, conceived, made or acquired by the Employee
                  during the period of his Employment and (ii) be binding upon
                  the Employee's assigns, executors, administrators and other
                  legal representatives.

      9.    GENERAL PROVISIONS

            A.    SEVERABILITY. If any one or more of the provisions of this
                  Agreement shall, for any reason, be held or found by final
                  judgment of a court of competent jurisdiction to be invalid,
                  illegal or unenforceable in any respect, (i) such invalidity,
                  illegality or unenforceability shall not affect any other
                  provisions of this Agreement, (ii) this Agreement shall be
                  construed as if such invalid, illegal or unenforceable
                  provision had never been contained herein (except that this
                  clause (ii) shall not prohibit any modification allowed under
                  Section 7(B)), and (iii) if the effect of a holding or finding
                  that any such provision is invalid, illegal or unenforceable
                  is to modify to the Employee's detriment, reduce or eliminate
                  any compensation, reimbursement, payment, allowance or other
                  benefit to the Employee intended by the Company and Employee
                  in entering into this Agreement, the Company shall, within
                  thirty (30) days after the date of such finding or holding,
                  negotiate and expeditiously enter into an agreement with the
                  Employee which contains alternative provisions (reasonably
                  acceptable to the Employee) that will restore to the Employee
                  (to the extent lawfully permissible) substantially the same
                  economic, substantive and income tax benefits and legal rights
                  the Employee would have enjoyed had such provision been upheld
                  as legal, valid and enforceable.

            B.    NONEXCLUSIVITY OF RIGHTS. Nothing herein shall prevent or
                  limit the Employee's continuing or future participation in any
                  Compensation Plan or, subject to Section 9(N), limit or
                  otherwise affect such rights as the Employee may have under
                  any other contract or agreement with the

                                       23
<PAGE>
                  Company. Vested benefits and other amounts to which the
                  Employee is or becomes entitled to receive under any
                  Compensation Plan on or after the Termination Date shall be
                  payable in accordance with that Compensation Plan, except as
                  expressly modified hereby.

            C.    FULL SETTLEMENT. The Company's obligations to make the
                  payments provided for in, and otherwise to perform its
                  undertakings in, this Agreement shall not be affected by any
                  right of set-off, counterclaim, recoupment, defense or other
                  action, claim or right the Company may have against the
                  Employee or others. In no event shall the Employee be
                  obligated to seek other employment or take any other action by
                  way of mitigation of the amounts payable to the Employee under
                  any provision hereof, and those amounts shall not be reduced,
                  regardless of whether the Employee obtains other employment or
                  becomes self-employed.

            D.    SUCCESSORS.

                  (i) This Agreement is personal to the Employee and, without
                  the prior written consent of the Company, is not assignable by
                  the Employee otherwise than by will or the laws of descent and
                  distribution. This Agreement shall inure to the benefit and be
                  enforceable by the Employee's legal representatives acting in
                  their capacities as such pursuant to applicable law.

                  (ii) This Agreement shall inure to the benefit of and be
                  binding upon the Company and its successors and assigns. If
                  the Employee is not an Executive Officer, but is an officer of
                  a subsidiary of the Company, the Company shall be entitled to
                  assign all its obligations hereunder to that subsidiary and
                  treat the Employee as an employee of that subsidiary for all
                  purposes, but the Company shall remain liable for the full,
                  timely performance of all the obligations so assigned as if
                  the assignment had not been made.

                  (iii) The Company shall require any successor (direct or
                  indirect and whether by purchase, merger, consolidation, share
                  exchange or otherwise) to the business, properties and assets
                  of the Company substantially as an entirety expressly to
                  assume and agree to perform this Agreement in the same manner
                  and to the same extent the Company would have been required to
                  perform it had no such succession taken place.

            E.    AMENDMENTS; WAIVERS. This Agreement may not be amended or
                  modified except by a written agreement executed and delivered
                  by the parties hereto or their respective successors or legal
                  representatives acting in their capacities as such pursuant to
                  applicable law.

            G.    NO WAIVER. The failure of the Company or the Employee to
                  insist on strict compliance with any provision of, or to

                  the Employee to terminate his Employment for Good Reason or by
                  reason of a Change of Control pursuant to Section 5(B) (i))
                  shall not be deemed a waiver of that provision or of any other
                  provision of or right under this Agreement.

            H.    GOVERNING LAW.  THIS AGREEMENT SHALL BE GOVERNED

                  venue of any such action, suit or other legal proceeding in
                  any of such courts.

            J.    HEADINGS. The headings of Sections and subsections hereof are
                  included solely for convenience of reference and shall not

                  of this Agreement.

            K.    INTEREST. If any amounts required to be paid or reimbursed to
                  the Employee hereunder are not so paid or reimbursed at the
                  times provided herein (including amounts required to be paid
                  by the Company pursuant to Sections 6 and 10, those amounts
                  shall accrue interest compounded daily at the annual
                  percentage rate which is three percentage points (3%) above
                  the interest rate announced by Texas Commerce Bank National
                  Association, Houston, Texas (or its successor), from time to
                  time, as its Base Rate (or prime lending rate), from the date
                  those amounts were required to have been paid or reimbursed to
                  the Employee until those amounts are finally and fully paid or
                  reimbursed; provided, however, that in no event shall the
                  amount of interest contracted for, charged or received
                  hereunder exceed the maximum non-usurious amount of interest
                  allowed by applicable law.

            L.    PUBLICITY. The Company agrees with the Employee that, except
                  to the extent required by law or legal process (including the
                  Exchange Act and the Securities Act), it will not make or
                  publish, without the prior written consent of the Employee,
                  any written or oral statement concerning the terms of the
                  Employee's employment relationship with the Company and will
                  not, if a Notice of Termination is given by either the Company
                  or the Employee for any reason, publish or cause to be
                  published any statement concerning the Employee, including his
                  work-related performance or the reasons or basis for the
                  giving of that Notice of Termination.

            M.    TAX WITHHOLDING. Notwithstanding any other provision hereof,
                  the Company may withhold from amounts payable hereunder all
                  Federal, state, local and foreign taxes that are required to
                  be withheld by applicable laws or regulations.

            N.    ENTIRE AGREEMENT. The Company and the Employee (i) acknowledge
                  that this Agreement supersedes all prior written and oral
                  agreements between them with respect to the employment of the
                  Employee by the Company.

<PAGE>
            A.    INTENDED BENEFITS; PAYMENT OF EXPENSES. In entering into this
                  Agreement the Company intends that the Employee receive
                  without reduction or delay all the intended benefits of this
                  Agreement and that those benefits, and the terms and
                  conditions hereof, be construed in a manner most favorable to
                  the Employee; the Company, therefore, agrees that it will
                  strive expeditiously and in good faith to construe and resolve
                  in the Employee's favor and to his benefit any ambiguities or
                  uncertainties that may be created by the express language
                  hereof. If, however, at any time during the term hereof or
                  afterwards: (i) there should exist a dispute or conflict
                  between the Employee and the Company or another Person as to
                  the validity, interpretation or application of any term or
                  condition hereof, or as to the Employee's entitlement to any
                  benefit intended to be bestowed hereby, which is not resolved
                  to the satisfaction of the Employee, (ii) the Employee must

                  attorney's fees, expenses of investigation, travel, lodging,

                  entitled, upon application to any court of competent
                  jurisdiction, to the entry of a mandatory injunction without

                  Section 10(A) will not be affected if the Employee is not the

                  in Section 10(A) arises between the Company and the Employee

                  resolve that dispute, prior to either party initiating any
                  litigation to resolve that dispute (not including any
                  litigation that may be required to enforce the Employee's
                  rights to the

<PAGE>
                  payment or advancement of expenses and legal fees on a current
                  basis pursuant to Section 10(A)) shall be to submit the
                  dispute to an agreed Alternative Dispute Resolution ("ADR")
                  process, to which process the parties shall strive diligently
                  in good faith to agree within ten (10) business days after
                  either party has given written notice to the other party that
                  it is unable to concur in the other party's final proposed
                  negotiated resolution of the dispute. If the Company and the
                  Employee are unable to agree in writing to an acceptable ADR
                  process within that ten (10) business day period, then the
                  parties shall submit to a mandatory ADR process by making
                  joint application to the then Chief United States Federal
                  District Judge in the Southern District of Texas for the
                  selection of an ADR process for the parties. The parties shall
                  diligently in good faith participate in the ADR process chosen
                  by that judge. If the parties are unable to resolve their
                  dispute after diligent good faith participation in the ADR
                  process, then either party shall be free to initiate such
                  litigation as that party deems appropriate under the
                  circumstances. Under no circumstances shall the Employee be
                  obligated to pay for the cost of any ADR process or to pay or
                  reimburse the Company for any attorneys' fees, costs or other
                  expenses incurred by the Company in connection with any
                  process undertaken by the Employee to resolve disputes under
                  this Agreement. As used in this Section 10, the term
                  "Employee" includes, if the Employee has died or become
                  incompetent as a matter of applicable law, the Employee's
                  legal representative acting in his capacity as such under
                  applicable law.

      11.   INDEMNIFICATION

            The Employee shall be indemnified by the Company to the maximum
            extent permitted by the law of Delaware, the state of the Company's
            incorporation, and the law of the state of incorporation of any
            subsidiary of the Company of which the Employee is a director or an
            officer or employee, as the same may be in effect from time to time.

      In entering into this Agreement, the Company desires to provid the
Employee with substantial incentives to serve the Company as a senior executive

distraction or concern over minimum compensation, benefits or tenure, to develop
and implement the Company's initial development plan and thereafter assist in
managing the Company's future growth and development and maximizing the returns
to the Company's stockholders.

      NOW, THEREFORE, in consideration of the foregoing and the mutual prov

                  with all Affiliates and Associates of such Person, is or are

                  the shares of Common Stock then outstanding, but does not
                  include any Exempt Person; provided, however, that a Person
                  shall not be or become an Acquiring Person if such Person,

                  Beneficial Owner of twenty-five percent (25%) or more of the

                  outstanding due to the repurchase of Common Stock by the
                  Company, unless and until such time as such Person or any
                  Affiliate or Associate of such Person shall purchase or
                  otherwise become the Beneficial Owner of additional shares of
                  Common Stock constituting one percent (1%) or more of the then

                  state without a personal income tax on the date hereof which

                  increase multiplied by seventy percent (70%) of the highest

                  Employee relocates from a state without a personal income tax
                  to a state having a personal income tax and the highest rate
                  of that tax is six percent (6%) when the Base Salary is
                  $200,000, then the Base Salary will be increased by $8,400
                  (computed at 70% x 6% x $200,000); provided, however, that the
                  obligation of the Company to pay the Base Salary earned by the

                  occur of (a) the IPO Closing Date, (b) the Termination Date or
                  (c) such other date as the Board in its sole discretion may
                  determine shall be deferred to the last day of that period in
                  such amounts as the Board in its sole discretion may from time
                  to time determine, on which day the Company shall pay in full
                  to the Employee, without interest, the aggregate earned but
                  unpaid amount of the Base Salary for that period. Effective as
                  of the Separation Effective Date, the Base Salary theretofore
                  in effect shall be adjusted as provided in Section 5(E).

                  paid or incurred. The Company hereby agrees to pay such
                  additional compensation within the earlier to occur of (i)
                  five (5) business days after the Employee notifies the Company
                  that the Employee intends to file a tax return taking the
                  position that such excise or similar purpose tax is due and
                  payable in reliance on a written opinion of the Employee's tax
                  counsel

                                       11
<PAGE>
                  (such tax counsel to be chosen solely by the Employee) that it
                  is more likely than not that such excise tax is due and
                  payable or (ii) twenty-four (24) hours of any notice of or
                  action by the Company that it intends to take the position
                  that such excise tax is due and payable. The costs of
                  obtaining the tax counsel opinion referred to in clause (i) of
                  the preceding sentence shall be borne by the Company, and as
                  long as such tax counsel was chosen by the Employee in good
                  faith, the conclusions reached in such opinion shall not be
                  challenged or disputed by the Company. If the Employee intends
                  to make any payment with respect to any such excise or similar
                  purpose tax as a result of an adjustment to the Employee's tax
                  liability by any federal, state or local tax authority, the
                  Company will pay such additional compensation by delivering
                  its cashier's check payable in such amount to the Employee
                  within five (5) business days after the Employee notifies the
                  Company of his intention to make such payment. Without
                  limiting the obligation of the Company hereunder, the Employee
                  agrees, in the event the Employee makes any payment pursuant
                  to the preceding sentence, to negotiate with the Company in
                  good faith with respect to procedures reasonably requested by
                  the Company which would afford the Company the ability to
                  contest the imposition of such excise or similar purpose tax;
                  provided, however, that the Employee will not be required to
                  afford the Company any right to contest the applicability of
                  any such excise or similar purpose tax to the extent that the
                  Employee reasonably determines (based upon the opinion of his
                  tax counsel) that such contest is inconsistent with the
                  overall tax interests of the Employee.

      5.    TERMINATION, SEPARATION PERIOD, DISABILITY AND DEATH

            A.    TERMINATION OF EMPLOYMENT BY THE COMPANY.

                  (i) The Company shall be entitled, if acting at the direction
                  of the Required Board Majority, to terminate the Employee's
                  Employment (a) at any time for Cause or (b) subject to the
                  payments obligations of the Separation Period, at any time
                  without Cause. The Company's termination of the Employee's
                  Employment hereunder will be effective on

                                       12
<PAGE>
                  the date the Company delivers a Notice of Termination for
                  Cause to the Employee pursuant hereto. Subject to the payment
                  provisions applicable to the Separation Period, the Employee
                  shall be required to vacate the premises of the Company, with
                  all of the Employee's personal property no later than five (5)
                  business days after the Notice of Termination.

                  (ii) If the Company terminates the Employee's Employment for
                  Cause, the Company promptly thereafter, and in any event
                  within five (5) business days thereafter, shall pay the
                  Employee his Base Salary to and including the end of the
                  calendar month of the Termination Date and the amount of all
                  compensation previously deferred by the Employee (together
                  with any accrued interest or earnings thereon), in each case
                  to the extent not theretofore paid, and, when that payment is
                  made, the Company shall, notwithstanding Section 3, have no
                  further or other obligations hereunder to the Employee.

                  (iii) If the Company otherwise terminates the Employee's
                  Employment, the respective rights and obligations of the
                  Company and the Employee during the Separation Period will be
                  as set forth in Section 5(E).

            B.    TERMINATION OF EMPLOYMENT BY THE EMPLOYEE.

                  (i) The Employee shall be entitled to terminate his
                  Employment, other than for Disability, at any time after one
                  hundred eighty (180) days after a Notice of Termination, (b)
                  by reason of a Change of Control at any time within three
                  hundred sixty-five (365) days after that Change of Control
                  occurs, or (c) at any time after thirty (30) days after
                  receipt of a Notice of Termination for material breach of any
                  provision of this Agreement, and the Company has not cured
                  that breach during the thirty (30) day period. The Employee's
                  termination of his Employment by reason of a Change of Control
                  will be effective on the first date on which the Change of
                  Control Payment shall have been paid in full to the Employee.
                  The Employee's termination of his Employment pursuant to (a)
                  and (b) above shall be effective on the Termination Date,
                  subject to the payment obligations of the Company during the
                  Separation Period.

                  (ii) If the Employee terminates his Employment by reason of a
                  Change of Control, the Company shall pay to the Employee in a
                  cash lump sum within five (5) business days after the date the
                  Company receives the Employee's Notice of Termination by
                  reason of that Change of Control

                                       13
<PAGE>
                  the amount equal to the sum of (a) the portion of the Base
                  Salary to and including the Termination Date which has not yet
                  been paid, (b) all compensation previously deferred by the
                  Employee (together with any accrued interest and earnings
                  thereon), (c) any accrued but unpaid vacation pay and (d) the
                  Change of Control Payment.

                  (iii) If the Employee terminates his Employment, other than
                  for Disability, the Company shall pay to the Employee, in a
                  cash lump sum within five (5) business days after the
                  Termination Date, the amount equal to the sum of (a) the
                  portion of the Base Salary to and including the Termination
                  Date which has not yet been paid, (b) all compensation
                  previously deferred by the Employee (together with any accrued
                  interest and earnings thereon) which has not yet been paid,
                  (c) any accrued but unpaid vacation pay and (d) the amount
                  equal to fifty percent (50%) of the Base Salary being paid for
                  the calendar year in which the Company receives the Employee's
                  Notice of Termination, and other than for Disability.

            C.    TERMINATION BY REASON OF DISABILITY. If the Employee incurs
                  any Disability during the term hereof, either the Employee or
                  the Company may terminate the Employee's Employment effective
                  on the third (3rd) anniversary of the date the Nonterminating
                  Party receives a Notice of Termination from the Terminating
                  Party pursuant to this Section 5(C). If the Employee's
                  Employment is terminated by reason of the Employee's
                  Disability, the respective rights and obligations of the
                  Company and the Employee during the Separation Period will be
                  as set forth in Section 5(E).

            D.    TERMINATION OF EMPLOYMENT BY DEATH. The Employee's Employment
                  shall terminate during the term hereof automatically at the
                  time of his death. If the Employee's Employment is terminated
                  by reason of the Employee's death, the Company shall pay to
                  the Person the Employee has designated in a written notice
                  delivered to the Company as his beneficiary entitled to such
                  payment, if any, or to the Employee's estate, as applicable,
                  in a cash lump sum within thirty (30) days after the
                  Termination Date, the amount equal to the sum of (i) the
                  portion of the Base Salary through the end of the month in
                  which the Termination Date occurs which has not yet been paid,
                  (ii) all compensation previously deferred by the Employee
                  (together with any accrued interest or earnings thereon) which
                  has not yet been paid, (iii) any accrued but unpaid vacation

                                       14
<PAGE>
                  pay and (iv) (a) the product of the Base Salary being paid for
                  the calendar year of death multiplied by three (3).

            E.    EMPLOYEE'S PAYMENT RIGHTS DURING THE SEPARATION PERIOD.

                  (i) The Company shall pay the Employee a Base Salary, in the
                  intervals consistent with the Company's normal payroll
                  schedules (but in no event less frequently than semi-monthly)
                  from the Separation Effective Date to and including the third
                  anniversiary thereof in the amounts determined from time to
                  time as follows: the Base Salary payable by the Company to the
                  Employee shall be as follows:

                        (a) if the Separation Effective Date occurs as a result
                        of the receipt by the Nonterminating Party of a Notice
                        of Termination other than for Cause, the amount equal to
                        the Average Annual Cash Compensation of the Employee
                        determined as of the Separation Effective Date; and (b)
                        if the Separation Effective Date occurs as a result of
                        the receipt by the Nonterminating Party of a Notice of
                        Termination for Disability pursuant to Section 5(C), the
                        amount equal to the amount by which (1) seventy-five
                        percent (75%) of the Average Annual Cash Compensation of
                        the Employee determined as of the Part-time Employment
                        Effective Date exceeds (2) the aggregate amount of
                        periodic payments the Employee receives during the
                        thirty-six (36) months beginning on that date under
                        Compensation Plans then in effect and providing for the
                        payment to the Employee solely as a result or on account
                        of disability; and

                        (b) on the first and each subsequent anniversary of the
                        Separation Date, the Base Salary payable pursuant to
                        this Section 5(E) shall be increased (but not decreased)
                        by the same percentage increase (if any) in the CPI for
                        the twelve (12) month period immediately preceding that
                        anniversary.

                  (ii)  (a) The Employee shall continue to participate in all
                        Compensation Plans from time to time in effect during
                        the Separation Period, provided, however, that: (1) the
                        Employee shall not be entitled to receive any new award
                        or grant under any incentive plan, and any such new
                        award or grant shall be at the

                                       15
<PAGE>
                        sole discretion of the Compensation Committee or the
                        Board, as applicable, with respect to that incentive
                        plan; and (2) if (A) the terms of any such plan preclude
                        the Employee's continued participation therein or (B)
                        his continued participation in any such plan would or
                        reasonably could be expected to disqualify that plan
                        under the Code, the Employee shall not be entitled to
                        participate in that plan, but the Company instead shall
                        provide the Employee with the after-tax equivalent of
                        the benefits that would have been provided to the
                        Employee were a participant in that plan.

                        (b) For purposes of determining eligibility (including
                        years of service) for retirement benefits payable under
                        any Compensation Plan, the Employee shall be deemed to
                        have retired at the Termination Date.

                  (iii) Subject to the provisions of Section 7, the Employee
                  shall not be prevented from accepting other employment or
                  engaging in (and devoting substantially all his time to) other
                  business activities and shall not be required to perform any
                  regular duties for the Company, and the Employee may seek or
                  accept additional employment with any other Person. If the
                  Employee, at his discretion, shall accept any such additional
                  employment or engage in any such other business activity there
                  shall be no offset, reduction or effect upon any rights,
                  benefits or payments to which the Employee is entitled
                  pursuant to this Agreement. Furthermore, the Employee shall
                  have no obligation to account for, remit, rebate or pay over
                  to the Company any compensation or other amounts earned or
                  derived in connection with such additional employment or
                  business activity.

                        The Employee shall, however, make himself generally
                  available for special projects or to consult with the Company
                  and its employees at such times and at such places as may be
                  reasonably requested by the Company and which shall be
                  reasonably satisfactory to the Employee and consistent with
                  the Employee's regular duties and responsibilities in the
                  course of his then new occupation or other employment, if any.

                  (iv) Unless and until the Employee shall have sustained a
                  Disability, the Company shall continue to provide the Employee
                  with either the same or, at the Company's election, at a
                  different location within thirty-five (35) miles of the
                  Employee's principal residence, in any case reasonably

                                       16
<PAGE>
                  acceptable to the Employee, alternate but comparable office
                  space, furnishings, facilities, reserved parking, supplies,
                  services, equipment, secretarial and administrative assistance
                  that are in each case at least commensurate with the size and
                  quality of that which were provided to the Employee during the
                  calendar year immediately preceding the Separation Effective
                  Date pursuant to Section 6(C), but in no event less than are
                  being furnished or provided on the date hereof. The Company
                  and Employee may mutually agree upon an equivalent monthly
                  cash allowance in lieu of the Employee being provided all or
                  any part of these items. 

                  (v) The Employee shall remain entitled to the benefits of
                  Section 4(C).

            F.    RETURN OF PROPERTY. On termination of the Employee's
                  Employment, however brought about, the Employee (or his
                  representatives) shall promptly deliver and return to the
                  Company all the Company's property that is in the possession
                  or under the control of the Employee.

            G.    STOCK OPTIONS. Notwithstanding any provision of this Agreement
                  to the contrary: (i) except in the case of a termination of
                  the Employee's Employment for Cause, all stock options
                  previously granted to the Employee under incentive plans that
                  have not been exercised and are outstanding as of the time
                  immediately prior to the Termination Date shall,
                  notwithstanding any contrary provision of any applicable
                  incentive plan, remain outstanding (and continue to become
                  exercisable pursuant to their respective terms) until
                  exercised or the expiration of their term, whichever is
                  earlier; and (ii) in the case of a termination of the
                  Employee's Employment for Cause, all stock options previously
                  granted to the Employee under incentive plans that have not
                  been exercised and are outstanding as of the time immediately
                  prior to the Termination Date shall, notwithstanding any
                  contrary provision of any applicable incentive plan, remain
                  outstanding and continue to be exercisable until exercised or
                  the date that is ten (10) days after the Termination Date,
                  whichever is earlier. No stock option previously granted to
                  the Employee under any incentive plan shall, notwithstanding
                  any contrary provision of that incentive plan, expire or fail
                  to become exercisable or, if exercisable, cease to be
                  exercisable by reason of the occurrence of the Employee's

      6.    OTHER EMPLOYEE RIGHTS

                                       17
<PAGE>
            A.    PAID VACATION; HOLIDAYS. The Employee shall be entitled to not
                  less than four (4) weeks of annual vacation and all legal
                  holidays during which times his applicable compensation shall
                  be paid in full. Further, it is understood by the Employee
                  that all paid vacation days shall be taken by or on December
                  31 of the calender year. Any and all vacation days which were
                  not taken by said date, shall be paid to the Employee on the
                  second pay period of the following January.

            B.    BUSINESS EXPENSES. The Employee is authorized to incur, and
                  will be entitled to receive prompt reimbursement for, all
                  reasonable expenses incurred by the Employee in performing his
                  duties and carrying out his responsibilities hereunder,
                  including business meal, entertainment and travel expenses,
                  provided that the Employee complies with the applicable
                  policies, practices and procedures of the Company relating to
                  the submission of expense reports, receipts or similar
                  documentation of those expenses. The Company shall either pay
                  directly or promptly reimburse the Employee for such expenses
                  not more than twenty (20) days after the submission to the
                  Company by the Employee from time to time of an itemized
                  accounting of such expenditures for which direct payment or
                  reimbursement is sought. Unpaid reimbursements after such
                  twenty (20) day period shall accrue interest in accordance
                  with Section 9(K).

            C.    SUPPORT. During the term hereof, the Employee shall be
                  provided by the Company with office space, furnishings, and
                  facilities, reserved parking, secretarial and administrative
                  assistance, supplies and other support equipment (including a
                  computer, facsimile machine and photocopier). 

      7.    COVENANT NOT TO COMPETE

            A.    The Employee re ognizes that in each of the highly competitive
                  businesses in which the Company is engaged, personal contact
                  is of primary importance in securing new orthodontic practices
                  and in retaining the accounts and goodwill of present
                  practices and protecting the business of the Company. The
                  Employee, therefore, agrees that during the term of Employment
                  and for a period of one (1) year after the Termination Date,
                  Employee will not, within fifty (50) miles of the corporate
                  headquarters: (i) accept employment or render service to any
                  Person that is engaged in a business directly competitive with
                  the business then engaged in by the

                                       18
<PAGE>
                  Company or (ii) enter into or take part in or lend Employee's
                  name, counsel or assistance to any business, either as
                  proprietor, principal, investor, partner, director, officer,
                  employee, consultant, advisor, agent, independent contractor,
                  or in any other capacity whatsoever, for any purpose that
                  would be competitive with the business of the Company.

            B.    If the provisions of this Section 7 are violated in any
                  material respect, the Company shall be entitled, upon
                  application to any court of proper jurisdiction, to a
                  temporary restraining order or preliminary injunction (without
                  the necessity of posting any bond with respect thereto) to
                  restrain and enjoin the Employee from that violation. If the
                  provisions of this Section 7 should ever be deemed to exceed
                  the time, geographic or occupational limitations permitted by
                  the applicable law, the Employee and the Company agree that
                  such provisions shall be and are hereby reformed to the
                  maximum time, geographic or occupational limitations permitted
                  by the applicable law.

      8.    CONFIDENTIAL INFORMATION

            A.    The Employee acknowledges that the Employee has had and will
                  continue to have access to various Confidential Information.
                  The Employee agrees, therefore, that Employee will not at any
                  time, either while employed by the Company or afterwards,
                  knowingly make any independent use of, or knowingly disclose
                  to any other person (except as authorized by the Company) any
                  Confidential Information. Confidential Information shall not
                  include (i) information that becomes known to the public
                  generally through no fault of the Employee, (ii) information
                  required to be disclosed by law or legal process or the order
                  of any governmental authority under color of law, provided,
                  that prior to disclosing any information pursuant to this
                  clause (ii), the Employee shall, if possible, give prior
                  written notice thereof to the Company and provide the Company
                  with the opportunity to contest such disclosure, or (iii) the
                  Employee reasonably believes that such disclosure is required
                  in connection with the defense of a lawsuit against the
                  Employee. In the event of a breach or threatened breach by the
                  Employee of the provisions of this Section 8(A) with respect
                  to any Confidential Information, the Company shall be entitled
                  to a temporary restraining order and a preliminary and
                  permanent injunction (without the necessity of posting any
                  bond in connection therewith) restraining the Employee from
                  disclosing, in whole or in part, that Confidential
                  Information. Nothing herein shall be construed as prohibiting
                  the

                                       19
<PAGE>
                  Company from pursuing any other available remedy for that
                  breach or threatened breach, including the recovery of
                  damages.

            B.    The Employee shall disclose promptly to the Company any and
                  all conceptions and ideas for inventions, improvements, and
                  valuable discoveries, whether patentable or not, which are
                  conceived or made by the Employee solely or jointly with any
                  other Person or Persons during the term of Employment and
                  which pertain primarily to the material business activities of
                  the Company, and the Employee hereby assigns and agrees to
                  assign all his interests therein to the Company or to its
                  nominee; whenever requested to do so by the Company, the
                  Employee shall execute any and all applications, assignments
                  or other instruments which the Company shall deem necessary to
                  apply for and obtain Letters of Patent of the United States or
                  any foreign country or to otherwise protect the Company's
                  interest therein. These obligations shall (i) continue beyond
                  the Termination Date with respect to inventions, improvements,
                  and valuable discoveries, whether patentable or not,
                  conceived, made or acquired by the Employee during the term of
                  Employment and (ii) be binding upon the Employee's assigns,
                  executors, administrators and other legal representatives.

      9.    GENERAL PROVISIONS

            A.    SEVERABILITY. If any one or more of the provisions of this
                  Agreement shall, for any reason, be held or found by final
                  judgment of a court of competent jurisdiction to be invalid,
                  illegal or unenforceable in any respect, (i) such invalidity,
                  illegality or unenforceability shall not affect any other
                  provisions of this Agreement, (ii) this Agreement shall be
                  construed as if such invalid, illegal or unenforceable
                  provision had never been contained herein (except that this
                  clause (ii) shall not prohibit any modification allowed under
                  Section 7(B)), and (iii) if the effect of a holding or finding
                  that any such provision is invalid, illegal or unenforceable
                  is to modify to the Employee's detriment, reduce or eliminate
                  any compensation, reimbursement, payment, allowance or other
                  benefit to the Employee intended by the Company and Employee
                  in entering into this Agreement, the Company shall, within
                  thirty (30) days after the date of such finding or holding,
                  negotiate and expeditiously enter into an agreement with the
                  Employee which contains alternative provisions (reasonably
                  acceptable to the Employee) that will restore to the Employee
                  (to the extent lawfully permissible) substantially the same
                  economic,

                                       20
<PAGE>
                  substantive and income tax benefits and legal rights the
                  Employee would have enjoyed had such provision been upheld as
                  legal, valid and enforceable.

            B.    NONEXCLUSIVITY OF RIGHTS. Nothing herein shall prevent or
                  limit the Employee's continuing or future participation in any
                  Compensation Plan or, subject to Section 9(N), limit or
                  otherwise affect such rights as the Employee may have under
                  any other contract or agreement with the Company. Vested
                  benefits and other amounts to which the Employee is or becomes
                  entitled to receive under any Compensation Plan on or after
                  the Termination Date shall be payable in accordance with that
                  Compensation Plan, except as expressly modified hereby.

            C.    FULL SETTLEMENT. The Company's obligations to make the
                  payments provided for in, and otherwise to perform its
                  undertakings in, this Agreement shall not be affected by any
                  right of set-off, counterclaim, recoupment, defense or other
                  action, claim or right the Company may have against the
                  Employee or others. In no event shall the Employee be
                  obligated to seek other employment or take any other action by
                  way of mitigation of the amounts payable to the Employee under
                  any provision hereof, and those amounts shall not be reduced,
                  regardless of whether the Employee obtains other employment or
                  becomes self-employed.

            D.    SUCCESSORS.

                  (i) This Agreement is personal to the Employee and, without
                  the prior written consent of the Company, is not assignable by
                  the Employee otherwise than by will or the laws of descent and
                  distribution. This Agreement shall inure to the benefit and be
                  enforceable by the Employee's legal representatives acting in
                  their capacities as such pursuant to applicable law.

                  (ii) This Agreement shall inure to the benefit of and be
                  binding upon the Company and its successors and assigns. If
                  the Employee is not an Executive Officer, but is an officer of
                  a subsidiary of the Company, the Company shall be entitled to
                  assign all its obligations hereunder to that subsidiary and
                  treat the Employee as an employee of that subsidiary for all
                  purposes, but the Company shall remain liable for the full,
                  timely performance of all the obligations so assigned as if
                  the assignment had not been made.

                                       21
<PAGE>
                  (iii) The Company shall require any successor (direct or
                  indirect and whether by purchase, merger, consolidation, share
                  exchange or otherwise) to the business, properties and assets
                  of the Company substantially as an entirety expressly to
                  assume and agree to perform this Agreement in the same manner
                  and to the same extent the Company would have been required to
                  perform it had no such succession taken place.

            E.    AMENDMENTS; WAIVERS. This Agreement may not be amended or
                  modified except by a written agreement executed and delivered
                  by the parties hereto or their respective successors or legal
                  representatives acting in their capacities as such pursuant to
                  applicable law.

            F.    NOTICES. All notices and other communications under this
                  Agreement shall be in writing and shall be given by hand
                  delivery or by registered or certified mail, return receipt
                  requested, postage prepaid, addressed to the appropriate
                  Person at the address of such Person set forth below (or at

                              Attn:  Corporate Secretary

            G.    NO WAIVER. The failure of the Company or the Employee to
                  insist on strict compliance with any provision of, or to
                  assert any right under, this agreement (including the right of
                  the Employee to terminate his Employment for Good Reason or by
                  reason of a Change of Control pursuant to Section 5(B)(i))
                  shall not be deemed a waiver of that provision or of any other
                  provision of or right under this Agreement.

            H.    GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED

                                       22

                  LAWS.

            I.    JURISDICTION AND VENUE. The Company irrevocably consents with
                  respect to any action, suit or other legal proceeding
                  pertaining directly to this Agreement or to the interpretation
                  or enforcement of any of the Employee's rights hereunder to
                  service of process in the State of Texas and hereby waives any
                  right to contest or oppose receipt of such service of process.

                  or other legal proceeding may be brought in the courts of such
                  state or in the courts of the United States sitting in such
                  state, (ii) consents to the jurisdiction of each such court in
                  any such action, suit or other legal proceeding, and (iii)
                  waives any objection it may have to the laying of venue of any
                  such action, suit or other legal proceeding in any of such
                  courts.

            J.    HEADINGS. The headings of Sections and subsections hereof are

                  the Employee hereunder are not so paid or reimbursed at the
                  times provided herein (including amounts required to be paid
                  by the Company pursuant to Sections 6 and 10, those amounts
                  shall accrue interest compounded daily at the annual
                  percentage rate which is three percentage points (3%) above
                  the interest rate announced by Texas Commerce Bank National
                  Association, Houston, Texas (or its successor), from time to
                  time, as its Base Rate (or prime lending rate), from the date
                  those amounts were required to have been paid or reimbursed to
                  the Employee until those amounts are finally and fully paid or
                  reimbursed; provided, however, that in no event shall the
                  amount of interest contracted for, charged or received
                  hereunder exceed the maximum non-usurious amount of interest
                  allowed by applicable law.

            L.    PUBLICITY. The Company agrees with the Employee that, except
                  to the extent required by law or legal process (including the

                  publish, without the prior written consent of the Employee,
                  any written or oral statement concerning the terms of the
                  Employee's employment relationship with the Company and

                  published any statement concerning the Employee, including his
                  work-related performance or the reasons or basis for the
                  giving of that Notice of Termination.

            M.    TAX WITHHOLDING. Notwithstanding any other provision hereof,
                  the Company may withhold from amounts payable hereunder all
                  Federal, state, local and foreign taxes that are required to

                  Plan and Agreement of Merger, the Company and the Employee (i)

                  and oral agreements between them with respect to the

                  afterwards: (i) there should exist a dispute or conflict
                  between the Employee and the Company or another Person as to
                  the validity, interpretation or application of any term or
                  condition hereof, or as to the Employee's entitlement to any
                  benefit intended to be bestowed hereby, which is not resolved
                  to the satisfaction of the Employee, (ii) the Employee must
                  (a) defend the validity of this Agreement, (b) contest any
                  determination by the Company concerning the amounts payable
                  (or reimbursable) by the Company to the Employee, or (c)
                  determine in any tax year of the Employee the tax consequences
                  to the Employee of any amounts payable (or reimbursable) under
                  Section 4(c) or 4(B)(iii), or (iii) the Employee must prepare
                  responses to an Internal Revenue Service ("IRS") audit of, or
                  otherwise defend, his personal

                  income tax return for any year the subject of any such audit,
                  or an adverse determination, administrative proceedings or
                  civil litigation arising therefrom that is occasioned by or
                  related to an audit by the IRS of the Company's income tax
                  returns, then the Company hereby unconditionally agrees: (a)
                  on written demand of the Company by the Employee, to provide
                  sums sufficient to advance and pay on a current basis (either
                  by paying directly or by reimbursing the Employee) not less
                  than thirty (30) days after a written request therefor is
                  submitted by the Employee, the Employee's out of pocket costs
                  and expenses (including attorney's fees, expenses of
                  investigation, travel, lodging, copying, delivery services and
                  disbursements for the fees and expenses of experts, etc.)
                  incurred by the Employee in connection with any such matter;
                  (b) the Employee shall be entitled, upon application to any
                  court of competent jurisdiction, to the entry of a mandatory
                  injunction without the necessity of posting any bond with
                  respect thereto which compels the Company to pay or advance
                  such costs and expenses on a current basis; and (c) the
                  company's obligations under this Section 10(A) will not be
                  affected if the Employee is not the prevailing party in the
                  final resolution of any such matter.

legal, accounting and other professional advisor services in connection with

those personnel performing patient care services subject to the professional
supervision of Orthodontist while such personnel are performing such patient
care services. If Orthodontist is dissatisfied with the services of any person,

whether the performance of that employee could be brought to acceptable levels
through counsel and assistance, or whether such employee should be reassigned or
terminated. All of Apple's obligations regarding staff shall be governed by the
overriding principle and goal of providing high quality orthodontic care.
Employee assignments shall be made to assure consistent and continued rendering
of high quality orthodontic support services and to ensure prompt availability
and accessibility of individual orthodontic support personnel to orthodontists
in order to develop constant, familiar and routine working relationships between
individual orthodontists and individual members of the orthodontic support
personnel. Apple shall maintain established working relationships wherever
possible and Apple shall make every effort consistent with sound business
practices to honor the specific requests of Orthodontist with regard to the
assignment of its employees. Apple shall provide administrative services such as

Employees. Apple and the Orthodontic Entity shall use their best efforts to
define who are their respective employees for all administrative purposes.

        SECTION 3.8 QUALITY ASSURANCE. Apple shall assist the Orthodontic Entity

such consideration for purposes of determining the amount of revenues received
by the Orthodontic Entity or Orthodontist. From time to time, the Orthodontic

patients which shall be reasonable in relation to fees generally being obtained
in the same or similar market areas. Notwithstanding any provision of this

Agreement, with respect to the Premises, Personal Property and tradenames,
trademarks and other intangible assets of Apple or AOI utilized by the

<PAGE>
               (c) knowingly and willfully make or cause to be made a false
        statement or representation of a material fact for use in determining
        rights to any benefit or payment; and

               (d) fail to disclose knowledge by a claimant of the occurrence of
        any event affecting the initial or continued right to any benefit or

shall not merge or consolidate with any other entity or individual or liquidate
or dissolve or wind-up Orthodontist's or the Orthodontic Entity's affairs or
enter into any partnerships, joint ventures or sale-leaseback transactions or
purchase or otherwise acquire (in one or a series of transactions) any part of
the property or assets of any other person or entity without the prior written
consent of Apple. Apple's consent shall be required for the Orthodontist to
provide orthodontic services at a location other than the Orthodontic Entity or

        SECTION 4.7 PREMISES AND PERSONAL PROPERTY. The Orthodontic Entity and

        SECTION 4.8   ORTHODONTIC ENTITY EMPLOYEE BENEFIT PLANS.

               (a) Effective immediately before the Acquisition Closing Date,
        the Orthodontic Entity and Orthodontist shall freeze or terminate all
        "employee benefit plans" (as that term is defined in Section 3(3) of the
        Employee Retirement Income Security Act of 1974, as amended ("ERISA"))
        that are (i) sponsored or maintained by the Orthodontic Entity or
        Orthodontist and (ii) are set forth on SCHEDULE 4.8(A) (the "Practice
        Plans"). In connection with such actions, all account balances and
        accrued benefits under all tax-qualified Practice Plans (within the
        meaning of Section 401(a) of the Code) shall be made fully vested and
        nonforfeitable.

               (b) Effective on the Acquisition Closing Date, Orthodontist shall
        become a participating employer in AOI's employee benefit plans set
        forth on SCHEDULE 4.8(B) (the "AOI Plans") with respect to
        Orthodontist's employees. Orthodontist acknowledges that AOI will
        sponsor a defined contribution plan and that Orthodontist may be
        precluded by Section 401(k)(2)(B)(i) from paying distributions in
        connection with the termination of

                                       14
<PAGE>
        any Practice Plan that contains a "cash or deferred arrangement" within
        the meaning of Section 401(k) of the Code. Accordingly, AOI shall take
        all actions as it may determine to be reasonable to facilitate the
        merger of the assets and liabilities of any tax-qualified Practice Plan
        into a tax-qualified AOI Plan if such merger of tax-qualified plans is
        requested by Orthodontist.

               (c) With respect to any Practice Plan or AOI Plan, neither
        Orthodontist nor AOI shall take any action or make any contribution to
        such plan that would cause such plan to become disqualified for federal
        tax purposes. Orthodontist shall not adopt, maintain, or continue any
        employee benefit plan after the Acquisition Closing Date without the
        prior written approval of AOI.

               (d) Expenses incurred in connection with Practice Plans,
        including without limitation the compensation of counsel, accountants,
        corporate trustees, and other agents shall be Excluded Orthodontic
        Entity and Orthodontist Expenses.

               (e) The contribution and administration expenses for the
        Orthodontist, Orthodontic Entity Professional Employees (which are not
        expenses payable by the AOI Plans or by the participants in the AOI
        Plans) shall be included in Orthodontist's operating budget.
        Orthodontist and AOI shall not make employee benefit plan contributions
        or payments for their respective employees in excess of such budgeted
        amounts unless required by law or the terms of the AOI Plans. AOI shall
        make contributions or payments with respect to the AOI Plans on behalf
        of eligible Orthodontic Entity Professional Employees and Orthodontic
        Entity Employees and those contributions or payments shall be treated as
        Orthodontic Entity and Orthodontist Expenses, Apple Expenses or Excluded
        Orthodontic Entity and Orthodontist Expenses as elsewhere provided in
        this Agreement.

               (f) AOI shall have the sole and exclusive authority to adopt,
        amend, or terminate any employee benefit plan for the benefit of its
        employees and employees of other entities aggregated with AOI pursuant
        to Section 414(b), (c), (m) (o) of the Code.

        SECTION 4.9 PEER REVIEW. Orthodontist and the Orthodontic Entity agree
to cooperate with Apple in establishing a system of peer review within and among
the orthodontic practices associated with Apple or its Affiliates. In connection
therewith, Orthodontist and the Orthodontic Entity agree to assist in the
formulation of orthodontic provider guidelines for each treatment or modality.

        SECTION 4.10 ADDITIONAL ORTHODONTISTS. The Orthodontic Entity and
Orthodontist shall require, as a condition to an additional orthodontist
becoming a shareholder of the Orthodontic Entity, that such shareholder execute
an agreement in form and substance similar to this Agreement or become a party
to this Agreement by amendment hereto.

        Orthodontist's full business time and attention to rendering
        professional services on behalf of the Orthodontic Entity and in
        furtherance of the Orthodontic Entity's best interest.

               (b) Orthodontist hereby agrees that during the period set forth

        influence any employee of the AOI Group to terminate his or her
        employment, or to hire any such employee, whether or not so induced or
        influenced, except that any such employee may be hired with the prior

         Orthodontist's ability
        to pursue a proper livelihood. Orthodontist agrees that the
        noncompetition restrictions set forth in this Agreement are reasonable
        as to time and geographic area.

        Notwithstanding the foregoing, however, this SECTION shall not prohibit
        Orthodontist or any of his or her Affiliates (including the Orthodontic
        Entity) from purchasing or holding an aggregate publicly traded equity

hereby agrees that during the term of this Agreement, it will not engage or

        SECTION 5.9 REMEDIES. Apple, Orthodontist and the Orthodontic Entity
acknowledge and agree that a remedy at law for any breach or attempted breach of
the provisions of this ARTICLE shall be inadequate, and therefore, either party
shall be entitled to specific performance and injunctive or other equitable
relief in the event of any such breach or attempted breach, in addition to any
other rights or remedies available to either party at law or in equity. Each
party hereto waives any requirement for the securing or posting of any bond in
connection with the obtaining of any such injunctive or other equitable relief.
If any provision of the restrictive covenants contained in the Orthodontic
Entity Professional Employment Agreements or this ARTICLE relating to the
restrictive period, scope of activity restricted and/or the territory described
therein shall be declared by a court of competent jurisdiction to exceed the
maximum time period, scope of activity restricted or geographical area such
court deems reasonable and enforceable under applicable law, the time period,
scope of activity restricted and/or area of restriction held reasonable and
enforceable by the court shall thereafter be the restrictive period, scope of
activity restricted and/or the territory applicable to such provision of the
restrictive covenants or this ARTICLE . The invalidity or non-enforceability of
any provision of the restrictive covenants or this ARTICLE in any respect shall
not affect the validity or enforceability of the remainder of the restrictive
covenants or this ARTICLE or of any other provisions of this Agreement.

                                   ARTICLE VI

                       FINANCIAL AND SECURITY ARRANGEMENTS

        The Orthodontic Entity and Apple agree that the compensation set forth
in this ARTICLE is being paid to Apple in consideration of the services provided
and the substantial commitment and effort made by Apple hereunder and that such
fees have been negotiated at arm's length, and are fair and reasonable and
consistent with fair market value.

        SECTION 6.1 SERVICE FEES. Apple shall charge the Orthodontic Entity for
services on a monthly basis an amount equal to the sum of the following:

        (a) Apple shall receive a base annual fee (the "Base Fee") equal to
thirteen and one-half percent (13.5%) of Orthodontic Entity's and Orthodontist's
gross revenues received from patients for orthodontic services provided ("Cash
Receipts").

        (b) Apple shall receive a fee equal to $____________ to the extent that
Net Operating Amount is less than or equal to $__________.

                                       19
<PAGE>
        (c) Each month Apple shall be reimbursed for the amount of all
Orthodontic Entity and Orthodontist Expenses and all Excluded Orthodontic Entity
and Orthodontist Expenses recorded by Apple in accordance with the terms of this
Agreement.

        For purposes of this SECTION 6.1, "Net Operating Amount" for any month
shall mean the Orthodontic Entity's and Orthodontist's Cash Receipts less
Orthodontic Entity and Orthodontist Expenses on a cash basis.

        SECTION 6.2 EXCLUDED EXPENSES. Any amounts reimbursed to Apple under
Section 6.1(c) shall be available to reduce amounts due to Apple in future
months to the extent the Net Operating Amount for such future month exceeds 45%
of the Orthodontic Entity's and Orthodontist's Cash Receipts so long as the
applicable month to which this Section 6.2 applies is within the same calendar
year as the month in which the obligation to reimburse Apple for amounts under
Section 6.1(c) arose.

        SECTION 6.3 WORKING CAPITAL LOANS. As part of the services provided by
Apple hereunder, Apple may make available loans to assist the Orthodontic Entity
in maintaining reasonable cash flow for the payment of Excluded Orthodontic
Entity and Orthodontist Expenses.

        (a) Initial Working Capital. Apple shall make available to the
Orthodontic Entity an interest free line of credit ("Initial Working Capital
Line") for the initial working capital needs of the Orthodontic Entity, up to a
maximum amount equal to the reduction in Net Operating Amount attributable to
changes in patient payment schedules. The Orthodontic Entity shall be entitled
to draw funds from the Initial Working Capital Line up until six (6) months
after the Acquisition Closing Date ("Loan Termination Date"). The amount, if
any, of the Initial Working Capital Line outstanding on the Loan Termination
Date shall be repaid, in equal monthly installments (without interest) over a
two-year period commencing on the Loan Termination Date.

        (b) Subsequent Working Capital. Apple may make available to the
Orthodontic Entity loans for subsequent working capital requirements in amounts
not to exceed Excluded Orthodontic Entity and Orthodontic Expenses. Such loans
shall accrue interest beginning on the day of the advance at an interest rate
equal to the prime rate then in effect, plus 1%. The loans, if any, shall be
repaid to Apple out of the Net Operating Amount generated in subsequent months
and become immediately due and payable if the Orthodontist terminates his
employment with the Orthodontic Entity, for any reason.

        Any principle or interest paid to Apple by the Orthodontic Entity
pursuant to Sections 6.3(a) or 6.3(b) are Excluded Orthodontic Entity and
Orthodontist Expenses.

        SECTION 6.4 SECURITY AGREEMENT. To secure their obligations hereunder,
the Orthodontic Entity and Orthodontist shall execute a Security Agreement in
substantially the form attached hereto as EXHIBIT 6.4 (the "Security
Agreement"), which Security Agreement grants a security interest in all of the
Orthodontic Entity's and Orthodontist's accounts receivable (as more fully
described in the Security Agreement) to Apple. In addition, the Orthodontic
Entity and Orthodontist shall cooperate with Apple and execute all necessary
documents in connection with the pledge of such accounts receivable to Apple or
at Apple's option, its lenders. All

                                       20

collections in respect of such accounts receivable shall be deposited in a bank
account at a bank designated by Apple. To the extent that the Orthodontic Entity
or Orthodontist comes into possession of any payments in respect of such
accounts receivable, the Orthodontic Entity or Orthodontist shall promptly remit
such payments to Apple.

                                   ARTICLE VII

                                     RECORDS

                             INSURANCE AND INDEMNITY

        SECTION 8.1 INSURANCE TO BE MAINTAINED BY THE ORTHODONTIC ENTITY AND
ORTHODONTIST. During the term of this Agreement, the Orthodontic Entity and
Orthodontist shall maintain comprehensive professional liability insurance with
such carrier as determined jointly by Apple and the Orthodontic Entity, with
limits of not less than $1,000,000 per claim and with aggregate policy limits of
not less than $3,000,000 per orthodontist and a separate limit for the
Orthodontic Entity (each such amount being subject to adjustment every three
years based on cost of living increases during any such period) with such
deductible as is mutually agreeable by Apple and the Orthodontic Entity. All
malpractice premiums and deductibles related thereto that are paid by Apple
shall be included in Orthodontic Entity and Orthodontist Expenses. All costs,
expenses and liabilities incurred by Orthodontic Entity, Orthodontist or Apple
in excess of the limits of such policies shall be included in Excluded
Orthodontic Entity and Orthodontist Expenses. Apple shall have the option of
providing such professional liability insurance through an alternative program,
provided such program meets the requirements of the Insurance Commissioner of
the State of California. If Orthodontist's existing professional liability
insurance program is cancelled and replaced by a professional liability
insurance program initiated by Apple, Apple shall pay over to Orthodontist any
unearned professional liability insurance premiums paid by Orthodontist to the
extent Orthodontist's carrier pays such amounts to Apple.

        SECTION 8.2 INSURANCE TO BE MAINTAINED BY APPLE. During the term of this
Agreement, Apple will use reasonable efforts to provide and maintain, as a
Orthodontic Entity and Orthodontist Expense, comprehensive professional
liability insurance for all professional employees of Apple, and comprehensive
general liability and property insurance covering the Orthodontic Entity
premises and operations with such limits as determined reasonable and
appropriate by Apple and after obtaining the Orthodontic Entity's approval to
purchase any such insurance.

        SECTION 8.3 CONTINUING LIABILITY INSURANCE COVERAGE. The Orthodontic
Entity and Orthodontist shall obtain or require each of Orthodontist and their
Orthodontic Entity Professional Employees to obtain continuing liability
insurance coverage under either a "tail policy" or a "prior acts policy," with
the same limits and deductibles as the insurance coverage provided pursuant to
SECTION for each orthodontist associated with the Orthodontic Entity upon the
termination of such orthodontist's relationship with the Orthodontic Entity for
any reason. In the event that neither the Orthodontic Entity, Orthodontist nor
the Orthodontic Entity Professional Employees obtains such continuing liability
insurance coverage, Apple may do so. The costs of continuing liability insurance
coverage shall be included in Orthodontic Entity and Orthodontist Expenses
unless such cost is borne by Orthodontist or the Orthodontic Entity Professional
Employee.

        SECTION 8.4 ADDITIONAL INSUREDS. The Orthodontic Entity, Orthodontist
and Apple agree to use their reasonable efforts to have each other named as an
additional insured on the other's respective professional liability insurance
programs. The additional cost, if any, associated therewith shall be paid by
Apple and shall be a Orthodontic Entity and Orthodontist Expense.

or consultants of the Orthodontic Entity) harmless, from and against any and all
liabilities, losses, damages, claims, causes of action and expenses (including
reasonable attorneys' fees), whether or not covered by insurance (including

intentional acts, negligent acts or omissions by Orthodontist, the Orthodontic
Entity and/or its shareholders, agents, employees and/or subcontractors (other
than Apple or AOI) during the term of this Agreement. Apple shall indemnify,
defend and hold Orthodontist and the Orthodontic Entity, its officers,

insurance (including self-insured insurance and reserves) that are caused or
asserted to have been caused, directly or indirectly, by or as a result of the

        SECTION 10.1 ASSIGNMENT. Apple shall have the right to assign its rights
hereunder to AOI or any direct or indirect wholly owned subsidiary of Apple or
AOI. The Orthodontic Entity and Orthodontist hereby agree that Apple has the
right to grant a security interest in its rights

                                       26
<PAGE>
hereunder to any lending institution from which Apple or the AOI obtains
financing. The Orthodontic Entity and Orthodontist shall not have the right to
assign their rights or obligations hereunder (i) to any person who is not a
graduate of an accredited orthodontic program or (ii) to any person who is a
graduate of an accredited orthodontic program without the prior written consent
of Apple and AOI, which consent shall not be unreasonably withheld. In the event
the parties are unable to agree upon the reasonableness of any such assignment,
then each of Apple and the Orthodontist shall each promptly thereafter select an
arbitrator and Apple and the Orthodontist shall each give prompt notice to the
other of such appointment in writing. The two arbitrators first appointed under
the terms hereof shall, within five (5) days after receipt of notification of
selection, together select a third arbitrator. The decision of the majority of
arbitrators so appointed shall be final and binding upon the parties hereto and
may be enforced in any court of competent jurisdiction. The expense of the
arbitrators appointed by each party shall be borne by the party appointing such
arbitrator, and the expense of the third arbitrator shall be borne by both
parties equally. The arbitrators shall give prompt notice in writing of their
decision to each party.

        SECTION 10.2 AMENDMENTS. This Agreement shall not be modified or amended
except by a written document executed by both parties to this Agreement, and
such written modification(s) or amendment(s) shall be attached hereto.

        SECTION 10.3 WAIVER OF PROVISIONS. Any waiver of any terms and
conditions hereof must be in writing, and signed by the parties hereto. The
waiver of any of the terms and conditions of this Agreement shall not be
construed as a waiver of any other terms and conditions hereof.

        SECTION 10.4 ADDITIONAL DOCUMENTS. Each of the parties hereto agrees to
execute any document or documents that may be requested from time to time by the
other party to implement or complete such party's obligations pursuant to this
Agreement.

        SECTION 10.5 ATTORNEYS' FEES. If legal action is commenced by either
party to enforce or defend its rights under this Agreement, the prevailing party
in such action shall be entitled to recover its costs and reasonable attorneys'
fees in addition to any other relief granted.

        SECTION 10.6 CONTRACT MODIFICATIONS FOR PROSPECTIVE LEGAL EVENTS. In the
event any state or federal laws or regulations, now existing or enacted or
promulgated after the date hereof, are interpreted by judicial decision, a
regulatory agency or legal counsel in such a manner as to indicate that this
Agreement or any provision hereof may be in violation of such laws or
regulations, the Orthodontic Entity, Orthodontist and Apple shall amend this
Agreement as necessary to preserve the underlying economic and financial
arrangements between the Orthodontic Entity, Orthodontist and Apple and without
substantial economic detriment to either party. To the extent any act or service
required of Apple in this Agreement should be construed or deemed, by any
governmental authority, agency or court to constitute the practice of
orthodontics, the performance of said act or service by Apple shall be deemed
waived and forever unenforceable and the provisions of this SECTION shall be
applicable. Neither party shall claim or assert illegality as a defense to the
enforcement of this Agreement or any provision hereof; instead, any such
purported illegality shall be resolved pursuant to the terms of this SECTION and
SECTION . In the event any governmental authority, agency or

                                       27

        SECTION 10.7 PARTIES IN INTEREST; NO THIRD-PARTY BENEFICIARIES. Except
as otherwise provided herein, the terms and conditions of this Agreement shall
inure to the benefit of and be binding upon the respective heirs, legal

hereunder or thereunder.

        SECTION 10.8 ENTIRE AGREEMENT. This Agreement and the agreements
contemplated hereby constitute the entire agreement of the parties regarding the
subject matter hereof, and supersede all prior agreements and understandings,
both written and oral, among the parties, or any of them, with respect to the
subject matter hereof.

        SECTION 10.9 SEVERABILITY. If any provision of this Agreement is held to
be illegal, invalid or unenforceable under present or future laws effective
during the term hereof, such provision shall be fully severable and this
Agreement shall be construed and enforced as if such illegal, invalid or
unenforceable provision never comprised a part hereof; and the remaining
provisions hereof shall remain in full force and effect and shall not be
affected by the illegal, invalid or unenforceable provision or by its severance
herefrom. Furthermore, in lieu of such illegal, invalid or unenforceable
provision, there shall be added automatically as part of this Agreement a
provision as similar in its terms to such illegal, invalid or unenforceable
provision as may be possible and be legal, valid and enforceable.

        SECTION 10.10 GOVERNING LAW. THIS AGREEMENT AND THE RIGHTS AND

CONFLICTS OF LAWS) OF THE STATE OF CALIFORNIA. THE PARTIES AGREE THAT THIS
AGREEMENT SHALL BE PERFORMABLE IN CALIFORNIA.

        SECTION 10.11 NO WAIVER; REMEDIES CUMULATIVE. Apple shall not by any act
(except by written instrument pursuant to SECTION hereof), delay, indulgence,
omission or otherwise be deemed to have waived any right or remedy hereunder or
to have acquiesced in any default in or breach of any of the terms and
conditions hereof. No failure to exercise, nor any delay in exercising, on the
part of Apple, any right, power or privilege hereunder shall operate as a waiver
thereof. No single or partial exercise of any right, power or privilege
hereunder shall preclude any other or further exercise thereof or the exercise
of any other right, power or privilege. No remedy set forth in this Agreement or
otherwise conferred upon or reserved to any party shall be considered exclusive
of any other remedy available to any party, but the same shall be distinct,
separate and cumulative and may be exercised from time to time as often as
occasion may arise or as may be deemed expedient.

                              EMPLOYMENT AGREEMENT

      THIS EMPLOYMENT AGREEMENT (this "Agreement"), is entered into on March 20,
1997 by and between APPLE ORTHODONTIX, INC., a Delaware corporation (the
"Company") and H. STEVEN WALTON (the "Employee").

                               R E C I T A L S:

      In entering into this Agreement, the Company desires to provide he
Employee with substantial incentives to serve the Company as a senior executive
performing at the highest levels of leadership and stewardship, without
distraction or concern over minimum compensation, benefits or tenure, to develop
and implement the Company's initial development plan and thereafter assist in
managing the Company's future growth and development and maximizing the returns
to the Company's stockholders.

      NOW, THEREFORE, in consideration of the foregoing and the mutual provis
ons contained herein, and for other good and valuable consideration, the parties
hereto agree with each other as follows:

      1.    CERTAIN DEFINITIONS

            A.    CERTAIN DEFINITIONS. As used herein, the following terms have
                  the meanings assigned to them below:

                  "ACQUIRING PERSON" means any Person who or which, together
                  with all Affiliates and Associates of such Person, is or are
                  the Beneficial Owner of twenty-five percent (25%) or more of
                  the shares of Common Stock then outstanding, but does not
                  include any Exempt Person; provided, however, that a Person
                  shall not be or become an Acquiring Person if such Person,
                  together with its Affiliates and Associates, shall become the
                  Beneficial Owner of twenty-five percent (25%) or more of the
                  shares of Common Stock then outstanding solely as a result of
                  a reduction in the number of shares of Common Stock
                  outstanding due to the repurchase of Common Stock by the
                  Company, unless and until such time as such Person or any
                  Affiliate or Associate of such Person shall purchase or
                  otherwise become the Beneficial Owner of additional shares of
                  Common Stock constituting one percent (1%) or more of the then
                  outstanding shares of Common Stock or any other Person (or
                  Persons) who is (or collectively are) the Beneficial Owner of
                  shares of Common Stock constituting one percent (1%) or more
                  of the then outstanding shares of Common Stock shall become an
                  Affiliate or Associate of such Person,
<PAGE>
                  unless, in either such case, such Person, together with all
                  Affiliates and Associates of such Person, is not then the
                  Beneficial Owner of twenty-five percent (25%) or more of the
                  shares of Common Stock then outstanding.

                  "ACQUISITION" shall mean (a) the direct or indirect
                  acquisition (by merger, stock purchase, asset purchase or
                  otherwise), by the Company or any of its Affiliates, of all or
                  substantially all the equity interest in, or assets of, a
                  Person through which any business or enterprise is or is
                  proposed to be conducted or (b) the entry by the Company or
                  any of its Affiliates of any service agreement or similar
                  contract or arrangement (or the amendment of an existing
                  service agreement or similar contract or arrangement that
                  alters the amounts payable to the Company or any of its
                  Affiliates by such agreement, contract or arrangement) through
                  which the Company or such Affiliate shall provide management
                  services or similar assistance to any Person. The term
                  "Acquisition," however, does not include the opening by the
                  Company of a new orthodontic center (de novo start-up), unless
                  the Employee directly participates in the negotiation for the
                  new center and the treatment of such start-up as an
                  "Acquisition" for purposes of this Agreement is approved in
                  advance by the President of the Company; PROVIDED, HOWEVER,
                  THAT if the development of one or more start-up operations or
                  orthodontic or dental centers is an integral part of the basis
                  on which an Acquisition is made (or if revenue from any
                  start-up operations are included in the pro forma analysis
                  which form part of the basis upon which the Company effects an
                  Acquisition), then such start-up shall be considered an
                  "Acquisition."

                  "AFFILIATE" has the meaning ascribed to that term in Exchange
                  Act Rule 12b-2.

                  "ANNUAL CASH COMPENSATION" of the Employee for any calendar
                  year means the sum of the salary, bonus and commissions earned
                  by the Employee during that calendar year, including all
                  amounts deferred at the election of the Employee pursuant to a
                  Compensation Plan intended to qualify as a plan under Section
                  401(k) of the Code or otherwise. If salary, bonus or
                  commissions are paid in whole or in part in property other
                  than cash (such as Common Stock) the amount so paid shall be
                  the fair market value thereof on the date of payment.

                  "AVERAGE ANNUAL CASH COMPENSATION" of the Employee means, as
                  of the Separation Effective Date, the average of (a) the
                  Annual Cash Compensation earned by the Employee in each of the
                  two (2) calendar years next preceding that date or, if fewer
                  than two (2) calendar years have occurred prior to that date
                  and since the Effective Date, (b) the average of the Annual
                  Cash Compensation in any calendar year restated

                                       2
<PAGE>
                  on an annualized basis.

                  "BASE SALARY" means the guaranteed minimum annual salary
                  payable by the Company to the Employee pursuant to Section
                  4(A), plus the amount of commissions paid pursuant to 4(B) to
                  the Employee over the immediately preceding 12 months (or the
                  annualized amount of such commissions, if the determination of
                  Base Salary is made before the first anniversary of the IPO
                  Closing Date).

                  "BENEFICIAL OWNER" is as defined in Exchange Act Rule 13d-3.

                  "CAUSE" to permit the Company to terminate the Employee's
                  Employment pursuant to the terms hereof means: (a) the
                  Employee's final conviction of a felony crime that involved
                  moral turpitude or that enriched the Employee at the expense
                  of the Company; (b) the Employee's deliberate, intentional or
                  highly reckless continuing failure to substantially perform
                  his duties and responsibilities hereunder (except by reason of
                  the Employee's incapacity to perform his duties due to
                  physical or mental illness or injury) for a period of
                  forty-five (45) days after the CEO, Board or President has
                  delivered to the Employee a written demand for substantial
                  performance hereunder which specifically identifies the bases
                  for the determination that the Employee has not substantially
                  performed his duties and responsibilities hereunder (such
                  period being the "Grace Period"); provided that, for purposes
                  of clause (b) the Company shall not have Cause to terminate
                  the Employee's employment unless (1) at a meeting of the Board
                  called and held following the Grace Period in the city in
                  which the Company's principal executive offices are located of
                  which the Employee was given not less than 10 days prior
                  written notice and at which the Employee was afforded the
                  opportunity to appear and be heard, the Required Board
                  Majority shall adopt a written resolution setting forth the
                  Required Board Majority's determination that the Employee has
                  failed to substantially perform his duties hereunder and that
                  such failure has continued up to the end of the Grace Period.

                  "CHANGE OF CONTROL" means the occurrence of any of the
                  following events that occurs after the IPO Closing Date: (a)
                  any Person becomes an Acquiring Person; (b) at any time the
                  then Continuing Directors cease to constitute a majority of
                  the members of the Board; (c) a merger of the Company with or
                  into, or a sale by the Company of its properties and assets
                  substantially as an entirety to, another Person occurs and,

                                       3

                  Exempt Person, together with all Affiliates, shall be the
                  Beneficial Owner of twenty-five percent (25%) or more of the
                  total voting power of the then outstanding Voting Shares of
                  the Person surviving that transaction (in the case or a merger
                  or consolidation) or the Person acquiring those properties and
                  assets substantially as an entirety.

                  "CHANGE OF CONTROL PAYMENT" means at any time the amount equal
                  to three (3) times the Employee's highest Base Salary during

            B.    The Employee shall not, at any time during his Employment,
                  engage in any other activities unless those activities do not
                  interfere materially with the Employee's duties and
                  responsibilities for the Company at that time, except that the
                  Employee shall be entitled, subject to the provisions of
                  Section 7, (a) to continue with such activities as making and
                  managing his personal investments and participating in other
                  business or civic activities and (b) to serve on corporate or
                  other business, civic or charitable boards or committees and
                  trade association or similar boards or committees. The Company
                  shall not assign Employee duties inconsistent in any material
                  respect with the Employee's position as set forth above, or
                  otherwise diminish the Employee's position, duties or
                  responsibilities.

            C.    Pursuant to the terms and conditions of a Consulting Contract
                  dated __, 1996, between the Employee and the Company, the
                  Employee and the Company hereby agree to and ratify the
                  above-referenced Consulting Contract, and the Employee shall
                  serve as a consultant pursuant to that agreement from the date
                  hereof until the Effective Date.

      3. TERM OF EMPLOYMENT. Subject to the provisions of Section 5, the term of
the Employee's Employment shall be for a continually renewing term of three (3)
years commencing on the Effective Date and renewing ach day thereafter for an
additional day without any further action by either the Company or the Employee,
it being the intention of the parties that there shall be continuously a
remaining term of three (3) years' duration of the Employee's Employment until
an event has occurred as described in, or one of the parties shall have made an
appropriate election pursuant to, the provisions of Section 5. When the
Termination Date shall have occurred and the Company shall have paid to the
Employee all the applicable amounts Section 5 provides the Company shall pay as
a result of the termination of the Employee's Employment, including all amounts
accruing during the Separation Period, if any, this Agreement will terminate and
have no further force or effect, except that Sections 4(C), 8, 9, 10 and 11
shall survive that termination indefinitely and Section 7 shall survive for the
period of time provided for therein.

      4.    COMPENSATION

            A.    BASE SALARY. A Base Salary shall be payable to the Employee by
                  the Company as a guaranteed minimum annual amount hereunder
                  for each calendar year during the period from the Effective
                  Date to the the Termination Date, subject to the rights of the
                  Employee during the Separation Period. That Base Salary shall
                  be payable in the intervals consistent with the Company's
                  normal payroll schedules (but in no event less infrequently
                  than semi-monthly), shall be payable initially at the annual
                  rate of $130,000 and shall be increased (but not decreased or
                  adjusted other than as provided in Section 5) as follows:

                  (i) on the first and each subsequent anniversary of the
                  Effective Date, by the same percentage increase (if any) in
                  the CPI for the twelve (12) month period immediately preceding
                  such anniversary;

                  (ii) on the first and each subsequent anniversary of the
                  Effective Date, by such additional amount as shall be
                  determined in the sole discretion of the Compensation
                  Committee, but only in such form and to such extent as the

                                       11
<PAGE>
                  Compensation Committee may from time to time approve, as
                  evidenced by the written minutes or records of the
                  Compensation Committee and its written notices of such
                  determinations or approvals to the Employee; and

                  (iii) if the Employee relocates from a state without a
                  personal income tax at the time of his relocation to a state
                  having a personal income tax, or if the Employee resides in a
                  state without a personal income tax on the date hereof which
                  subsequently adopts a personal income tax, then, in either
                  case, the Base Salary in effect at the time of such relocation
                  or adoption, as applicable, shall immediately be increased by
                  the amount equal to the Base Salary immediately prior to this
                  increase multiplied by seventy percent (70%) of the highest
                  personal income tax rate of such state; for example, if the
                  Employee relocates from a state without a personal income tax
                  to a state having a personal income tax and the highest rate
                  of that tax is six percent (6%) when the Base Salary is
                  $200,000, then the Base Salary will be increased by $8,400
                  (computed at 70% x 6% x $200,000); provided, however, that the
                  obligation of the Company to pay the Base Salary earned by the
                  Employee for his service in the period beginning on the
                  Effective Date and ending on the date that is the first to
                  occur of (a) the IPO Closing Date, (b) the Termination Date or
                  (c) such other date as the Board in its sole discretion may
                  determine shall be deferred to the last day of that period in
                  such amounts as the Board in its sole discretion may from time
                  to time determine, on which day the Company shall pay in full
                  to the Employee, without interest, the aggregate earned but
                  unpaid amount of the Base Salary for that period. Effective as
                  of the Separation Effective Date, the Base Salary theretofore
                  in effect shall be adjusted as provided in Section 5(E).

      B.    COMMISSIONS.

                  (i) The Employee shall be entitled to receive a commission in
                  respect of every Acquisition effected by the Company or its
                  Affiliates. The amount of each such commission shall be equal
                  to the product of (x) $8,125, (y) the Incremental EPS
                  attributable to such Acquisition and (z) a fraction, the
                  numerator of which shall be the fully diluted number of shares
                  outstanding on the date of the closing of such Acquisition and
                  the denominator of which shall be the fully diluted number of
                  shares outstanding on the IPO Closing Date. In no event,
                  however, shall the commission payable to the Employee in
                  respect of any Acquisition effected by the Company or its
                  Affiliates be less than $4,000 (and, if an Acquisition
                  involves more than orthodontic or dental practice, $4,000 per
                  orthodontist or dentist whose practice is directly affected

                                       12
<PAGE>
                  by such Acquisition), which amount, as well as the dollar
                  amount set forth in (x) immediately above, shall be increased
                  on each anniversary of the Effective Date by the same
                  percentage increase (if any) in the CPI for the twelve (12)
                  month period immediately preceding such anniversary.

                  (ii) Each commission due to the Employee pursuant to (i) above
                  shall be paid in cash to the Employee no later than the 20th
                  day following the closing of the Acquisition in respect of
                  which the commission was earned; PROVIDED, HOWEVER, that, with
                  the mutual consent of the Employee and the Company,
                  commissions may be paid on the due date in Common Stock
                  (valued for such purpose at the average closing trading price
                  of such Common Stock over the five trading days ended
                  immediately before the closing date of such Acquisition) or in
                  Options (valued for such purpose using the Black-Shoales
                  formula for valuing stock options and applying such formula as
                  of the date of the closing of such Acquisition; any such
                  Options to have a duration of not less than 10 years and to be
                  fully vested and immediately exercisable on the date of
                  grant).

                  (iii) If in any annual period commencing on the IPO Date or
                  the anniversary of the IPO Date and ending on the day
                  immediately preceding the next anniversary of the IPO Date,
                  the commissions earned by the Employee shall exceed $162,500,
                  then each commission payable to the Employee pursuant to
                  Subsection 4.B.(i) above during the remainder of such annual
                  period shall be increased by 30%.

            C.    OTHER COMPENSATION.

                  (i) From the Effective Date until any Separation Effective
                  date, the Employee shall be entitled to participate in all
                  Compensation Plans, regardless of whether the Employee is an
                  Executive Officer. All awards to the Employee under all
                  Incentive Plans shall take into account the Employee's
                  positions with and duties and responsibilities to the Company
                  and its subsidiaries. The Company acknowledges that the
                  Employee's right to receive commissions under Section 4.B.
                  above is intended to incentivize the Employee to effect
                  profitable acquisitions on behalf of the Company, and to
                  compensate him for effecting such Acquisitions, and further
                  acknowledges that the Employee's commission rights shall not
                  impair the Employee's right to participate in Incentive Plans,
                  or to receive incentive bonuses, in respect of his services as
                  an Executive Officer of the Company.

                  (ii) Effective on the IPO Closing Date, the Company will pay
                  the Employee an amount equal to the sum of (a) $5,416.67 [1/2
                  the $130,000 base salary for the period from February 15 to
                  February 28] and (b) the product of $356.16 and the number of
                  days from February 28, 1997 to and including the IPO Closing
                  Date [the $130,000 base salary from March 1, 1997 to IPO
                  closing].

                  (iii) On the IPO Closing Date, the Company shall grant the
                  Employee the following Options:

                        (a) 85,000 Options with an exercise price equal to the
                        per share net proceeds received by the Company in the
                        IPO. Unless the vesting schedule for these Options is
                        otherwise accelerated pursuant to this Agreement or by
                        action of the Board of Directors of the Company (or an
                        authorized Committee of such Board), 1/4 of these
                        Options shall vest on the IPO Closing Date and 1/4 of
                        these Options shall vest on the first, second and third
                        anniversary of the IPO Closing Date.

                        (b) A number of Options equal to the number shares of
                        Common Stock into which 23.5 shares of such stock
                        outstanding on the date of this Agreement shall be split
                        or converted into as a result of or on completion of the
                        IPO. The exercise price for these options shall be equal
                        to the per share net proceeds received by the Company in
                        the IPO. Unless the vesting schedule for these Options
                        is otherwise accelerated pursuant to this Agreement or
                        by action of the Board of Directors of the Company (or
                        an authorized Committee of such Board), 1/2 of these
                        Options shall vest on the IPO Closing Date and 1/2 of
                        these Options shall vest on the first anniversary of the
                        IPO Closing Date.

                  (iv) During the term of this Agreement, the Employee shall be
                  entitled to receive such number of additional Options on such
                  terms as the Board of Directors of the Company (or an
                  authorized Committee of such Board) shall determine. The
                  Employee's right to receive such Options shall be independent
                  of, and set without regard to, the commission compensation
                  otherwise received by the Employee under this Agreement.

                                       14
<PAGE>
                  (v) Commencing on the IPO Closing Date, the Employee shall be
                  entitled to request and receive from the Company one or more
                  loans in an aggregate principal amount not to exceed the
                  aggregate exercise price of all Options issued to the Employee
                  pursuant to Subsection 4.C.(iv)(B) above. Each loan will be
                  used solely for the purpose of paying the exercise price of
                  Options. Each such loan will have a term of not less than 30
                  years, shall bear no interest, shall permit no recourse to the
                  Employee, the estate or heirs of the Employee or any assets of
                  the Employee or the Employee's estate or heirs and shall not
                  be subject to default or acceleration or any principal
                  amortization until the final maturity date of such loan. Upon
                  the exercise of any Options issued to the Employee pursuant to
                  Subsection 4.C.(iv)(B) above or sale by the Employee of any
                  shares of Common Stock acquired by the Employee upon such
                  exercise, the Company shall reimburse (and gross-up the
                  Employee for any deemed income or additional taxes owing as a
                  result of such reimbursement) the Employee for the state or
                  federal income taxes that result so as to ensure that the net
                  cost to the Employee for taxes, if any, imposed upon the
                  exercise of such Options and sale of such shares of Common
                  Stock shall be identical to the net tax cost the Employee
                  would have borne had the Company issued to the Employee on
                  December 9, 1996, 23.5 shares of Common Stock at a purchase
                  price of $1 per share.

                  TAX INDEMNITY. Should any of the payments of Base Salary,
                  other incentive or supplemental compensation, benefits,
                  allowances, awards, payments, reimbursements or other
                  perquisites, or any other payment in the nature of
                  compensation, singly, in any combination or in the aggregate,
                  that are provided for hereunder to be paid to or for the
                  benefit of the Employee be determined or alleged to be subject
                  to an excise or similar purpose tax pursuant to Section 4999
                  of the Code, or any successor or other comparable federal,
                  state or local tax law by reason of being a "parachute
                  payment" (within the meaning of Section 280G of the Code), the
                  Company shall pay to the Employee such additional compensation
                  as is necessary (after taking into account all federal, state
                  and local taxes payable by the Employee as a result of the
                  receipt of such additional compensation) to place the Employee
                  in the same after-tax position (including federal, state and
                  local taxes) he would have been in had no such excise or
                  similar purpose tax (or interest or penalties thereon) been
                  paid or incurred. The Company hereby agrees to pay such
                  additional compensation within the earlier to occur of (i)
                  five (5) business days after the Employee notifies the Company
                  that the Employee intends to

                                       15
<PAGE>
                  file a tax return taking the position that such excise or
                  similar purpose tax is due and payable in reliance on a
                  written opinion of the Employee's tax counsel (such tax
                  counsel to be chosen solely by the Employee) that it is more
                  likely than not that such excise tax is due and payable or
                  (ii) twenty-four (24) hours of any notice of or action by the
                  Company that it intends to take the position that such excise
                  tax is due and payable. The costs of obtaining the tax counsel
                  opinion referred to in clause (i) of the preceding sentence
                  shall be borne by the Company, and as long as such tax counsel
                  was chosen by the Employee in good faith, the conclusions
                  reached in such opinion shall not be challenged or disputed by
                  the Company. If the Employee intends to make any payment with
                  respect to any such excise or similar purpose tax as a result
                  of an adjustment to the Employee's tax liability by any
                  federal, state or local tax authority, the Company will pay
                  such additional compensation by delivering its cashier's check
                  payable in such amount to the Employee within five (5)
                  business days after the Employee notifies the Company of his
                  intention to make such payment. Without limiting the
                  obligation of the Company hereunder, the Employee agrees, in
                  the event the Employee makes any payment pursuant to the
                  preceding sentence, to negotiate with the Company in good
                  faith with respect to procedures reasonably requested by the
                  Company which would afford the Company the ability to contest
                  the imposition of such excise or similar purpose tax;
                  provided, however, that the Employee will not be required to
                  afford the Company any right to contest the applicability of
                  any such excise or similar purpose tax to the extent that the
                  Employee reasonably determines (based upon the opinion of his
                  tax counsel) that such contest is inconsistent with the
                  overall tax interests of

                  Cause, the Company promptly thereafter, and in any event

                  calendar month of the Termination Date and the amount of all
                  compensation previously deferred by the Employee (together
                  with any accrued interest or earnings thereon), in each case
                  to the extent not theretofore paid, and, when that payment is
                  made, the Company shall, notwithstanding Section 3, have no
                  further or other obligations hereunder to the Employee.

                  Employment, other than for Disability, (a) for Good Reason at
                  any time within one hundred eighty (180) days after facts or
                  circumstances constituting that Good Reason first exist or is
                  known to the Employee, but only after the Employee has given
                  the Company written notice of such Good Reason and it has not
                  been fully cured within 30 days following receipt of such
                  Notice, (b) by reason of a Change of Control at any time
                  within three hundred sixty-five (365) days after that Change
                  of Control occurs, or (c) without Good Reason and other than
                  for Disability at any time.. The Employee's termination of his

                  Period.

                  (ii) If the Employee terminates his Employment by reason of a
                  Change of Control, the Company shall pay to the Employee in a
                  cash lump sum within five (5) business days after the date the
                  Company receives the Employee's Notice of Termination by
                  reason of that Change of Control the amount equal to the sum
                  of (a) the portion of the Base Salary to and including the
                  Termination Date which has not yet been paid, (b) all
                  compensation previously deferred by the Employee (together
                  with any accrued interest and earnings thereon), (c) any
                  accrued but unpaid vacation pay and (d) the Change of Control
                  Payment.

                  (iii) If the Employee terminates his Employment, other than
                  for Disability, the Company shall pay to the Employee, in a
                  cash lump sum within five (5) business days after the
                  Termination Date, the amount equal to the sum of (a) the
                  portion of the Base Salary to and including the Termination
                  Date which has not yet been paid, (b) all compensation
                  previously deferred by the Employee (together with any accrued
                  interest and earnings thereon) which has not yet been paid,
                  (c) any accrued but unpaid vacation pay and (d) the amount
                  equal to fifty percent (50%) of the Base Salary being paid for
                  the calendar year in which the Company receives the Employee's
                  Notice of Termination, and other than for Disability.

                  (iv) If the Employee terminates his Employment for Good
                  Reason, the respective rights and obligations of the Company
                  and the Employee shall be as set forth in Section 5(E).

            C.    TERMINATION BY REASON OF DISABILITY. If the Employee incurs
                  any Disability during the term hereof, either the Employee or
                  the Company may terminate the Employee's Employment effective
                  on the third (3rd) anniversary of the date the Nonterminating
                  Party receives a Notice of Termination from the Terminating
                  Party pursuant to this Section 5(C). If the Employee's
                  Employment is terminated by reason of the Employee's
                  Disability, the respective rights and obligations of the
                  Company and the Employee during the Separation Period will be
                  as set forth in Section 5(E).

            D.    TERMINATION OF EMPLOYMENT BY DEATH. The Employee's Employment
                  shall terminate during the term hereof automatically at the
                  time of his death. If the Employee's Employment is terminated
                  by reason of the Employee's death, the Company shall pay to
                  the Person the Employee has designated in a written notice
                  delivered to the Company as his beneficiary entitled to such
                  payment, if any, or to the Employee's estate, as applicable,
                  in a cash lump sum within thirty (30) days after the
                  Termination Date, the amount equal to the sum of (i) the
                  portion of the Base Salary through the end of the month in
                  which the Termination Date occurs which has not yet been paid,
                  (ii) all compensation previously deferred by the Employee
                  (together with any accrued interest or earnings thereon) which
                  has not yet been paid, (iii) any accrued but unpaid vacation
                  pay and (iv) (a) the product of the Base Salary being paid for

                  (i) The Company shall pay the Employee a Base Salary, in the
                  intervals consistent with the Company's normal payroll
                  schedules (but in no event less frequently than semi-monthly)
                  from the Separation Effective Date to and including the third
                  anniversiary thereof in the amounts determined from time to
                  time as follows: the Base Salary payable by the Company to the
                  Employee shall be as follows:

                        (a) if the Separation Effective Date occurs as a result
                        of the receipt by the Nonterminating Party of a Notice
                        of Termination other than for Cause, the amount equal to
                        the Average Annual Cash Compensation of the Employee
                        determined as of the Separation Effective Date; and (b)
                        if the Separation Effective Date occurs as a result of
                        the receipt by the Nonterminating Party of a Notice of
                        Termination for Disability pursuant to Section 5(C), the
                        amount equal to the amount by which (1) seventy-five
                        percent (75%) of the Average Annual Cash Compensation of
                        the Employee determined as of the Part-time Employment
                        Effective Date exceeds (2) the aggregate amount of
                        periodic payments the Employee receives during the
                        thirty-six (36) months beginning on that date under
                        Compensation Plans then in effect and providing for the
                        payment to the Employee solely as a result or on account
                        of disability; and

                        (b) on the first and each subsequent anniversary of the
                        Separation Date, the Base Salary payable pursuant to
                        this Section 5(E) shall be increased (but not decreased)
                        by the same percentage increase (if any) in the CPI for
                        the twelve (12) month period immediately preceding that
                        anniversary.

                  (ii)  (a) The Employee shall continue to participate in all
                        Compensation Plans from time to time in effect during
                        the Separation Period, provided, however, that: (1) the
                        Employee shall not be entitled to receive any new award
                        or grant under any incentive plan, and any such new
                        award or grant shall be at the sole discretion of the
                        Compensation Committee or the Board, as applicable, with
                        respect to that incentive plan; and (2) if (A) the terms
                        of any such plan preclude the Employee's continued
                        participation therein or (B) his continued participation
                        in any such plan would or reasonably could be expected

                                       19
<PAGE>
                        to disqualify that plan under the Code, the Employee
                        shall not be entitled to participate in that plan, but
                        the Company instead shall provide the Employee with the
                        after-tax equivalent of the benefits that would have
                        been provided to the Employee were a participant in that
                        plan.

                        (b) For purposes of determining eligibility (including
                        years of service) for retirement benefits payable under
                        any Compensation Plan, the Employee shall be deemed to
                        have retired at the Termination Date.

                  (iii) Subject to the provisions of Section 7, the Employee
                  shall not be prevented from accepting other employment or
                  engaging in (and devoting substantially all his time to) other
                  business activities and shall not be required to perform any
                  regular duties for the Company, and the Employee may seek or
                  accept additional employment with any other Person. If the
                  Employee, at his discretion, shall accept any such additional
                  employment or engage in any such other business activity there
                  shall be no offset, reduction or effect upon any rights,
                  benefits or payments to which the Employee is entitled
                  pursuant to this Agreement. Furthermore, the Employee shall
                  have no obligation to account for, remit, rebate or pay over
                  to the Company any compensation or other amounts earned or
                  derived in connection with such additional employment or
                  business activity.

                        The Employee shall, however, make himself generally
                  available for special projects or to consult with the Company
                  and its employees at such times and at such places as may be
                  reasonably requested by the Company and which shall be
                  reasonably satisfactory t the Employee and consistent with the
                  Employee's regular duties and responsibilities in the course
                  of his then new occupation or other employment, if any.

                  (iv) Unless and until the Employee shall have sustained a
                  Disability, the Company shall continue to provide the Employee
                  with either the same or, at the Company's election, at a
                  different location within thirty-five (35) miles of the
                  Employee's principal residence, in any case reasonably
                  acceptable to the Employee, alternate but comparable office
                  space, furnishings, facilities, reserved parking, supplies,
                  services, equipment, secretarial and administrative assistance
                  that are in each case at least commensurate with the size and
                  quality of that which were provided to the Employee during the
                  calendar year immediately preceding the Separation Effective
                  Date pursuant to Section 6(C),

                  the date hereof. The Company and Employee may mutually agree
                  upon an equivalent monthly cash allowance in lieu of the
                  Employee being provided all or any part of these items. (v)
                  The Employee shall remain entitled to the benefits of Section
                  4(D).

            F.    RETURN OF PROPERTY. On termination of the Employee's
                  Employment, however brought about, the Employee (or his
                  representatives) shall promptly deliver and return to the
                  Company all the Company's property that is in the possession
                  or under the control of the Employee.

            G.    STOCK OPTIONS. Notwithstanding any provision of this Agreement
                  to the contrary: (i) except in the case of a termination of
                  the Employee's Employment for Cause, all stock options
                  previously granted to the Employee under this Agreement or
                  under incentive plans that have not been exercised and are
                  outstanding as of the time immediately prior to the
                  Termination Date shall, notwithstanding any contrary provision
                  of any applicable incentive plan, remain outstanding (and
                  continue to become exercisable pursuant to their respective
                  terms) until exercised or the expiration of their term,
                  whichever is earlier; and (ii) in the case of a termination of
                  the Employee's Employment for Cause, all stock options
                  previously granted to the Employee under this Agreement or
                  under incentive plans that have not been exercised and are
                  outstanding as of the time immediately prior to the
                  Termination Date shall, notwithstanding any contrary provision
                  hereof or of any applicable incentive plan, remain outstanding
                  and continue to be exercisable until exercised or the date
                  that is ten (10) days after the Termination Date, whichever is
                  earlier. No stock option previously granted to the Employee
                  under this Agreement or under any incentive plan shall,
                  notwithstanding any contrary provision of that incentive plan,
                  expire or fail to become exercisable or, if exercisable, cease
                  to be exercisable by reason of the occurrence of the
                  Employee's Separation Effective Date.

            A.    PAID VACATION; HOLIDAYS. The Employee shall be entitled to not
                  less than four (4) weeks of annual vacation and all legal
                  holidays during which times his applicable compensation shall
                  be paid in full. Further, it is understood by the Employee
                  that all paid vacation days shall be taken by or on December
                  31 of the calender year. Any and all vacation days which were
                  not taken by said date, shall be paid to the Employee on the

            B.    BUSINESS EXPENSES. The Employee is authorized to incur, and
                  will be entitled to receive prompt reimbursement for, all
                  reasonable expenses incurred by the Employee in performing his
                  duties and carrying out his responsibilities hereunder,
                  including business meal, entertainment and travel expenses,
                  provided that the Employee complies with the applicable
                  policies, practices and procedures of the Company relating to
                  the submission of expense reports, receipts or similar
                  documentation of those expenses. The Company shall either pay

                  Company by the Employee from time to time of an itemized
                  accounting of such expenditures for which direct payment or
                  reimbursement is sought. Unpaid reimbursements after such
                  twenty (20) day period shall accrue interest in accordance

                  apply to all expenses incurred by the Employee on behalf of
                  the Company, regardless of whether incurred before or after
                  the date of this Agreement. If the Company should relocate its
                  executive offices of this Agreement to a location more than 35
                  miles from the Company's then current executive offices, then
                  the Company will reimburse the Employee for all reasonable
                  expenses (and gross up the Employee for the additional income
                  taxes, if any, imposed on the Employee as a result of such
                  reimbursement and such gross up) incurred by the Employee as a
                  result of such relocation, including without limitation, (i)
                  the costs and expenses of moving and temporary housing for up
                  to six (6) months, (ii) the costs and expenses of searching
                  for a new residence, including at least two visits to the
                  metropolitan area of the new executive office by the Employee
                  and his family, (iii) the realtor commissions on the purchase
                  by the Employee of a new residence in the vicinity of the new
                  executive offices and on the disposition of his previous
                  residence in the vicinity of the previous executive
                  officesidence"), (iv) if the Employee should acquire a new
                  residence before he shall have disposed of the Previous
                  Residence, the mortgage payments, property taxes, insurance
                  charges, subdivision and maintenance fees and similar costs

                  residence, accruing until the date on which the Employee
                  disposes of the Previous Residence, but not to exceed six (6)
                  months, and (v) should the Employee sell the Previous
                  Residence following any such relocation for less than the sum
                  of (x) his cost-basis in the Previous Residence and (y) the
                  product of (x) and the average increase in the cost of homes
                  in the metropolitan area in which the Previous Residence is
                  located over the period from the original purchase of the

                  (and, in the case of improvements that are a material part of
                  the cost-basis, the date such improvements are made) to the
                  date of sale, then the difference between the sum of the
                  preceding (x) and (y) and the net sale price for the Previous
                  Residence.

            C.    SUPPORT. During the term hereof, the Employee shall be
                  provided by the Company with office space, furnishings, and
                  facilities, reserved parking, secretarial and administrative
                  assistance, supplies and other support equipment (including a
                  computer, facsimile machine and photocopier). The Company
                  agrees that it, and it's Executive Officers and other
                  employees will provide the Employee with reasonable assistance
                  in pursuing, evaluating and closing Acquisitions. .

      7.    COVENANT NOT TO COMPETE

            A.    The Employee recognizes that in each of the highly competitive
                  businesses in which the Company is engaged, personal contact
                  is of primary importance in securing new orthodontic practices
                  and in retaining the accounts and goodwill of present
                  practices and protecting the business of the Company. The
                  Employee, therefore, agrees that during the term of Employment
                  and for a period of one (1) year after the Termination Date,
                  Employee will not, within fifty (50) miles of the corporate
                  headquarters: (i) accept employment or render service to any
                  Person that is engaged in a business directly competitive with
                  the business then engaged in by the Company or (ii) enter into
                  or take part in or lend Employee's name, counsel or assistance
                  to any business, either as proprietor, principal, investor,
                  partner, director, officer, employee, consultant, advisor,
                  agent, independent contractor, or in any other capacity
                  whatsoever, for any purpose that would be competitive with the
                  business of the Company.

            B.    If the provisions of this Section 7 are violated in any
                  material respect, the Company shall be entitled, upon
                  application to any court of proper jurisdiction, to a
                  temporary restraining order or preliminary injunction (without
                  the necessity of posting any bond with respect thereto) to
                  restrain and enjoin the Employee from that violation. If the
                  provisions of this Section 7 should ever be deemed to exceed
                  the time, geographic or occupational limitations permitted by
                  the applicable law, the Employee and the Company agree that
                  such provisions shall be and are hereby reformed to the
                  maximum time, geographic or occupational limitations permitted
                  by the applicable law.

      8.    CONFIDENTIAL INFORMATION

            A.    The Employee acknowledges that the Employee has had and will
                  continue to have access to various Confidential Information.
                  The Employee agrees, therefore, that Employee will not at any
                  time, either while employed by the Company or afterwards,
                  knowingly make any independent use of, or knowingly disclose
                  to any other person (except as authorized by the Company) any
                  Confidential Information. Confidential Information shall not
                  include (i) information that becomes known to the public
                  generally through no fault of the Employee, (ii) information
                  required to be disclosed by law or legal process or the order
                  of any governmental authority under color of law, provided,
                  that prior to disclosing any information pursuant to this
                  clause (ii), the Employee shall, if possible, give prior
                  written notice thereof to the Company and provide the Company
                  with the opportunity to contest such disclosure, or (iii) the
                  Employee reasonably believes that such disclosure is required
                  in connection with the defense of a lawsuit against the
                  Employee. In the event of a breach or threatened breach by the
                  Employee of the provisions of this Section 8(A) with respect
                  to any Confidential Information, the Company shall be entitled
                  to a temporary restraining order and a preliminary and
                  permanent injunction (without the necessity of posting any
                  bond in connection therewith) restraining the Employee from
                  disclosing, in whole or in part, that Confidential
                  Information. Nothing herein shall be construed as prohibiting
                  the Company from pursuing any other available remedy for that
                  breach or threatened breach, including the recovery of
                  damages.

            B.    The Employee shall disclose promptly to the Company any and
                  all conceptions and ideas for inventions, improvements, and
                  valuable discoveries, whether patentable or not, which are
                  conceived or made by the Employee solely or jointly with any
                  other Person or Persons during the term of Employment and
                  which pertain primarily to the material business activities of
                  the Company, and the Employee hereby assigns and agrees to
                  assign all his interests therein to the Company or to its
                  nominee; whenever requested to do so by the Company, the
                  Employee shall execute any and all applications, assignments
                  or other instruments which the Company shall deem necessary to
                  apply for and obtain Letters of Patent of the United States or
                  any foreign country or to otherwise protect the Company's
                  interest therein. These obligations shall (i) continue beyond
                  the Termination Date with respect to

                                       24
<PAGE>
                  inventions, improvements, and valuable discoveries, whether
                  patentable or not, conceived, made or acquired by the Employee
                  during the term of Employment and (ii) be binding upon the
                  Employee's assigns, executors, administrators and other legal
                  representatives.

      9.    GENERAL PROVISIONS

            A.    SEVERABILITY. If any one or more of the provisions of this
                  Agreement shall, for any reason, be held or found by final
                  judgment of a court of competent jurisdiction to be invalid,
                  illegal or unenforceable in any respect, (i) such invalidity,
                  illegality or unenforceability shall not affect any other
                  provisions of this Agreement, (ii) this Agreement shall be
                  construed as if such invalid, illegal or unenforceable
                  provision had never been contained herein (except that this
                  clause (ii) shall not prohibit any modification allowed under
                  Section 7(B)), and (iii) if the effect of a holding or finding
                  that any such provision is invalid, illegal or unenforceable
                  is to modify to the Employee's detriment, reduce or eliminate
                  any compensation, reimbursement, payment, allowance or other
                  benefit to the Employee intended by the Company and Employee
                  in entering into this Agreement, the Company shall, within
                  thirty (30) days after the date of such finding or holding,
                  negotiate and expeditiously enter into an agreement with the
                  Employee which contains alternative provisions (reasonably
                  acceptable to the Employee) that will restore to the Employee
                  (to the extent lawfully permissible) substantially the same
                  economic, substantive and income tax benefits and legal rights
                  the Employee would have enjoyed had such provision been upheld
                  as legal, valid and enforceable.

            B.    NONEXCLUSIVITY OF RIGHTS. Nothing herein shall prevent or
                  limit the Employee's continuing or future participation in any
                  Compensation Plan or, subject to Section 9(N), limit or
                  otherwise affect such rights as the Employee may have under
                  any other contract or agreement with the Company. Vested
                  benefits and other amounts to which the Employee is or becomes
                  entitled to receive under any Compensation Plan on or after
                  the Termination Date shall be payable in accordance with that
                  Compensation Plan, except as expressly modified hereby.

            C.    FULL SETTLEMENT. The Company's obligations to make the
                  payments provided for in, and otherwise to perform its
                  undertakings in, this Agreement shall not be affected by any
                  right of set-off, counterclaim, recoupment, defense or other
                  action, claim or right the Company may have against the

                                       25
<PAGE>
                  Employee or others. In no event shall the Employee be
                  obligated to seek other employment or take any other action by
                  way of mitigation of the amounts payable to the Employee under
                  any provision hereof, and those amounts shall not be reduced,
                  regardless of whether the Employee obtains other employment or
                  becomes self-employed.

            D.    SUCCESSORS.

                  (i) This Agreement is personal to the Employee and, without
                  the prior written consent of the Company, is not assignable by
                  the Employee otherwise than by will or the laws of descent and
                  distribution. This Agreement shall inure to the benefit and be
                  enforceable by the Employee's legal representatives acting in
                  their capacities as such pursuant to applicable law.

                  (ii) This Agreement shall inure to the benefit of and be
                  binding upon the Company and its successors and assigns. If
                  the Employee is not an Executive Officer, but is an officer of
                  a subsidiary of the Company, the Company shall be entitled to
                  assign all its obligations hereunder to that subsidiary and
                  treat the Employee as an employee of that subsidiary for all
                  purposes, but the Company shall remain liable for the full,
                  timely performance of all the obligations so assigned as if
                  the assignment had not been made.

                  (iii) The Company shall require any successor (direct or
                  indirect and whether by purchase, merger, consolidation, share
                  exchange or otherwise) to the business, properties and assets
                  of the Company substantially as an entirety expressly to
                  assume and agree to perform this Agreement in the same manner
                  and to the same extent the Company would have been required to
                  perform it had no such succession taken place.

            E.    AMENDMENTS; WAIVERS. This Agreement may not be amended or
                  modified except by a written agreement executed and delivered
                  by the parties hereto or their respective successors or legal
                  representatives acting in their capacities as such pursuant to
                  applicable law.

                  insist on strict compliance with any provision of, or to
                  assert any right under, this agreement (including the right of
                  the Employee to terminate his Employment for Good Reason or by

                  shall not be deemed a waiver of that provision or of any other
                  provision of or right under this Agreement.

            H.    GOVERNING LAW. THIS AGREEMENT SHALL BE GOVERNED BY, AND

                  work-related performance or the reasons or basis for the
                  giving of that Notice of Termination.

            M.    TAX WITHHOLDING. Notwithstanding any other provision hereof,
                  the Company may withhold from amounts payable hereunder all
                  Federal, state, local and foreign taxes that are required to
                  be withheld by applicable laws or regulations.

            N.    ENTIRE AGREEMENT. Except for the Consulting Agreement, the
                  Company and the Employee (i) acknowledge that this Agreement
                  supersedes all prior written and oral agreements between them
                  with respect to the employment of the Employee by the Company.

      10.   INTENDED BENEFITS TO EMPLOYEE; PAYMENT OF EXPENSES; RESOLUTION OF
            DISPUTES

            A.    INTENDED BENEFITS; PAYMENT OF EXPENSES. In entering into this
                  Agreement the Company intends that the Employee receive
                  without reduction or delay all the intended benefits of this
                  Agreement and that those benefits, and the terms and
                  conditions hereof, be construed in a manner most favorable

                                       27

                  to the Employee; the Company, therefore, agrees that it will
                  strive expeditiously and in good faith to construe and resolve
                  in the Employee's favor and to his benefit any ambiguities or
                  uncertainties that may be created by the express language
                  hereof. If, however, at any time during the term hereof or
                  afterwards: (i) there should exist a dispute or conflict
                  between the Employee and the Company or another Person as to
                  the validity, interpretation or application of any term or
                  condition hereof, or as to the Employee's entitlement to any
                  benefit intended to be bestowed hereby, which is not resolved
                  to the satisfaction of the Employee, (ii) the Employee must
                  (a) defend the validity of this Agreement, (b) contest any
                  determination by the Company concerning the amounts payable
                  (or reimbursable) by the Company to the Employee, or (c)
                  determine in any tax year of the Employee the tax consequences
                  to the Employee of any amounts payable (or reimbursable) under
                  Section 4(c) or 4(B)(iii), or (iii) the Employee must prepare
                  responses to an Internal Revenue Service ("IRS") audit of, or
                  otherwise defend, his personal income tax return for any year
                  the subject of any such audit, or an adverse determination,
                  administrative proceedings or civil litigation arising
                  therefrom that is occasioned by or related to an audit by the
                  IRS of the Company's income tax returns, then the Company
                  hereby unconditionally agrees: (a) on written demand of the
                  Company by the Employee, to provide sums sufficient to advance
                  and pay on a current basis (either by paying directly or by
                  reimbursing the Employee) not less than thirty (30) days after
                  a written request therefor is submitted by the Employee, the
                  Employee's out of pocket costs and expenses (including
                  attorney's fees, expenses of investigation, travel, lodging,
                  copying, delivery services and disbursements for the fees and
                  expenses of experts, etc.) incurred by the Employee in
                  connection with any such matter; (b) the Employee shall be
                  entitled, upon application to any court of competent
                  jurisdiction, to the entry of a mandatory injunction without
                  the necessity of posting any bond with respect thereto which
                  compels the Company to pay or advance such costs and expenses
                  on a current basis; and (c) the Company's obligations under
                  this Section 10(A) will not be affected if the Employee is not
                  the prevailing party in the final resolution of any such
                  matter.

      11.   INDEMNIFICATION

Pursuant to the express terms and conditions of the Certificate of Incorporation
and Bylaws of the Company, the Company hereby ratify and confirm and enter into
an express separate contract to provide that the Employee shall be held harmless

extent permitted by the law of Delaware, the state of the
